Referring to fig. 1 to 5, an embodiment of the invention provides a pair of body-building mirrors 100, including: a main body support 10, a mirror display module 20, a guide module 30, and a driving module 40.

The mirror display module 20 is mounted on the front surface of the main body frame 10.

The guide module 30 includes a first guide assembly 31 and a second guide assembly 32, the first guide assembly 31 and the second guide assembly 32 are respectively installed at left and right sides of the main body support 10, and the first guide assembly 31 is used for winding the first tension member 50, and the second guide assembly 32 is used for winding the second tension member 51.

Referring to fig. 6 to 8, the driving module 40 is installed inside the body frame 10, and includes a driving motor 41, two sets of tension adjusting mechanisms 42, a first reel 43, and a second reel 44.

First and

second reels

43, 44 are provided on opposite sides of the drive motor 41, respectively, the first reel 43 serving to provide a motion resistance to the first tension member 50, and the second reel 44 serving to provide a motion resistance to the second tension member 51.

Two sets of tension adjustment mechanisms 42 are provided between the first reel 43 and the drive motor 41 and between the second reel 44 and the drive motor 41, respectively, for adjusting the torque output by the drive motor 41 to the first reel 43 and the second reel 44.

The body-building mirror 100 in the embodiment of the present invention can be applied to a home, a gymnasium, a public place, and the like, and specifically includes a main body frame 10 and a mirror display module 20 installed on the front surface of the main body frame 10.

As shown in fig. 4 and 5, the main body frame 10 has a middle frame structure for mounting the respective modules, for example, the mirror display module 20 is mounted on the front surface of the main body frame 10, the guide modules 30 are mounted on the left and right sides thereof, and the driving module 40 is mounted inside thereof.

In one embodiment, as shown in fig. 1, the mirror display module 20 includes a display 21 and a mirror 22. The mirror 22 includes a total reflection area 221 and a partial reflection area 222. The partial reflection area 222 is disposed in front of the display 21, and is used for transmitting a video played by the display 21 and simultaneously reflecting a motion gesture image of the user when the display 21 is turned on, and is also used for reflecting a motion gesture image of the user when the display 21 is turned off. The total reflection region 221 is a mirror surface region other than the partial reflection region 222.

In the present embodiment, the mirror display module 20 includes a display 21 for displaying video contents and a mirror 22 for reflecting a user's movement posture.

Specifically, when the display 21 is turned on, the partially reflective region 222 transmits a video played by the display 21 while reflecting the motion gesture image of the user. The user's motion gesture image is displayed in the partially reflective region 222 overlaid with video content at this time to guide the user to take a correct gesture for fitness. When the display 21 is turned off, the partially reflective region 222 is hardly visible, and can totally reflect the motion gesture image of the user and block components (such as the driving module 40) inside the exercise mirror 100. The total reflection region 221 is used for totally reflecting the movement posture image of the user and shielding components inside the exercise mirror 100.

In addition, the exercise glass 100 has a speaker so that the user can listen to audio while watching video contents.

As shown in fig. 1, in one embodiment, the exercise mirror 100 further includes an embedded camera 70, and the embedded camera 70 is disposed in the main body frame 10 and corresponds to the partially reflective area 222 for capturing a video image through the partially reflective area 222.

Specifically, the embedded camera 70 is installed in the main body stand 10, for example, at a lower position or an upper position of the display module 20, and corresponds to the partial reflection area 222. Since the partially reflective region 222 is a semi-transparent structure, external light enters the embedded camera 70 through the partially reflective region 222, thereby forming a video image of the current user.

Further, in order to prevent the main body support 10 from shielding the embedded camera 70, the main body support 10 is provided with a collecting through hole corresponding to the embedded camera 70, and the embedded camera 70 is installed and fixed at the back of the main body support 10 and exposed from the collecting through hole, so that the external light of the exercise goggles 100 can sequentially penetrate through the partial reflection area 222 and pass through the collecting through hole to enter the embedded camera 70, and a video image of the current user is formed.

As shown in fig. 5 to 8, the drive module 40 is mounted inside the body frame 10, and the first and

second reels

43, 44 are steplessly regulated by the tension adjusting mechanism 42 so that the first and

second reels

43, 44 respectively apply the movement resistance to the first and

second tension members

50, 51, thereby finely adjusting the one-sided movement resistance.

Specifically, the first tensile member 50 and the second tensile member 51 each include a tensile cord. The fixed end of the tensile rope is connected with the driving module 40, and the free end can be formed with a tensile ring or provided with a tensile ring with certain rigidity, and the tensile ring or the tensile ring is held by a user to perform stretching movement. In this embodiment, the tensile cord is a steel cord having high tenacity, and the steel cord is not easily broken and can be used repeatedly.

It is understood that the motion resistance in the present embodiment is a driving force (also referred to as a load force) applied by the driving module 40 on the first or

second tension member

50 or 51, which is opposite to the pulling force applied by the user on the first or

second tension member

50 or 51. The exercise mirror 100 of this embodiment may have a plurality of preset resistance to movement, either in a factory setting or in a field setting (e.g., user field input). Through setting up a plurality of different preset movement resistance, can form multiple different body-building modes to carry out different strength to user's same muscle crowd and take exercise, thereby reach the purpose of body-building.

In actual use, a user holds the tension ring, and the driving module 40 applies movement resistance to the first tension member 50 and the second tension member 51 respectively. In the starting stage, when the force exerted on the tensile rope by the user is larger than the applied motion resistance, the tensile rope can be pulled; in the stationary phase, when the force applied to the tensile cord by the user is less than the applied movement resistance, for example, the user is relaxed, the tensile cord is retracted due to the driving module 40 continuously outputting the movement resistance to the tensile cord until the user applies the force greater than the movement resistance again, and the tensile cord is pulled out, and the process is repeated, so that the user continues to exercise.

For example, assuming that the preset total motion resistance is 100N, the total motion resistance of the driving module 40 exerted on the first tension member 50 and the second tension member 51 is 100N. If the total pulling force applied by the user to the first pulling force element 50 and the second pulling force element 51 is 120N and is greater than 100N of the preset total movement resistance, both the first pulling force element 50 and the second pulling force element 51 are pulled outwards by the user. When the user relaxes, for example, performs stretching exercise or rest, since the driving module 40 continues to output 100N of total exercise resistance to the first and

second tension members

50 and 51, the first and

second tension members

50 and 51 will retract until the user applies a force greater than the total exercise resistance again, the first and

second tension members

50 and 51 will not be pulled out, and so on, the user can continue to perform 100N of total exercise.

Further, the guide module 30 is used to change the tension direction and the stroke of the first tension member 50 and the second tension member 51 so as to exercise different muscle groups of the user, thereby achieving the purpose of exercise.

Specifically, as shown in fig. 3 and 4, the guide module 30 includes two sets of guide components: the first guide assembly 31 and the second guide assembly 32, two sets of guide assemblies are respectively arranged at the left and right sides of the main body support 10, and the first guide assembly 31 is wound around the first tension piece 50, and the second guide assembly 32 is wound around the second tension piece 51, so as to match the left and right hand exercise of the user.

Still further, as shown in fig. 6 to 8, the drive module 40 includes a drive motor 41, two sets of tension adjustment mechanisms 42, a first reel 43, and a second reel 44.

In the present embodiment, the number of the drive motors 41 is one, and the driving force of the drive motors 41 is distributed to the first reels 43 and the second reels 44 so that the first reels 43 provide the first tension member 50 with the motion resistance and the second reels 44 provide the second tension member 51 with the motion resistance, ensuring that the magnitude of the load is constant. The first reel 43 and the second reel 44 are independent of each other, and can rotate in the normal direction at the same time, rotate in one side without rotating, or rotate in the normal direction and reverse direction at one side, and both sides do not interfere with each other when being pulled by the same load.

Specifically, as shown in fig. 7, two output shafts of the drive motor 41 are drivingly connected to the first reel 43 and the second reel 44, respectively, to distribute the torque output from the drive motor 41 to the first reel 43 and the second reel 44 through the two output shafts thereof, independently. In one sub-embodiment, the drive motor 41 is a dc brushless motor. By precisely controlling the phase currents, it is ensured that the torque dynamics of the drive motor 41 are constant.

Further, two sets of tension adjusting mechanisms 42 are provided on the two output shafts of the drive motor 41, and the two sets of tension adjusting mechanisms 42 are provided between the first reel 43 and the drive motor 41 and between the second reel 44 and the drive motor 41, respectively. When the drive motor 41 drives the first and

second reels

43, 44 to rotate, the tension adjustment mechanism 42 also follows the rotation of the first and

second reels

43, 44, thereby independently applying a preset degree of friction torque to the first and

second reels

43, 44 to adjust the output torque distributed by the drive motor 41 to the first and

second reels

43, 44. In other words, the drive motor 41 and the tension adjustment mechanism 42 are each capable of applying output torques to the first reel 43 and the second reel 44, which may be superimposed.

It will be appreciated that, in order to meet different strength training requirements of users, such as training with the same strength for both hands, or training with different strengths for the difference in strength between both hands, the preset friction torque applied to the first reel 43 by the two sets of tension adjusting mechanisms 42 may be the same as or different from the preset friction torque applied to the second reel 44; in addition, the preset friction torque of the two sets of tension adjusting mechanisms 42 can be adjusted according to the requirements of users, so that the movement resistance can be accurately graded.

For example, one stage provides a base drive force of 10kg for the drive module 40. The second order is that each set of the tension adjusting mechanisms 42 applies a friction torque corresponding to 2kg on the basis of a driving force corresponding to 10kg, thereby adding a running resistance corresponding to 2kg to the first reel 43 or the second reel 44. Three stages are that each set of the tension adjusting mechanism 42 applies a friction torque corresponding to 4kg on the basis of a driving force corresponding to 10kg, thereby adding a running resistance corresponding to 4kg to the first reel 43 or the second reel 44. By parity of reasoning, grading of the motion resistance is realized.

During a specific operation, when the drag adjustment mechanism 42 does not apply a friction torque to the first reel 43 and the second reel 44, the output torque distributed to the first reel 43 and the output torque distributed to the second reel 44 by the drive motor 41 are generally the same, regardless of the loss, due to the symmetrical arrangement.

Illustratively, assuming that the total driving force of the driving module 40 is 50kg of driving force, the driving force applied to the first reel 43 is similar to the driving force applied to the second reel 44, for example, the first reel 43 provides 25kg of motion resistance to the first pull member 50, and the second reel 44 provides 25kg of motion resistance to the second pull member 51.

After the tension adjustment mechanism 42 applies the preset friction torque to the first reel 43 and the second reel 44, the output torque finally applied to the first reel 43 and the output torque finally applied to the second reel 44 may be the same or different, thereby satisfying different strength training requirements of users, since the two sets of preset friction torques applied by the two sets of tension adjustment mechanisms 42 may be the same or different, regardless of losses.

For example, assume that the total driving force of the driving module 40 is still 50kg of corresponding driving force.

In one embodiment, if the two sets of tension adjusting mechanisms 42 apply the same preset friction torque, the driving force ultimately applied to the first reel 43 is the same as the driving force applied to the second reel 44. For example, if both sets of tension adjusting mechanisms 42 apply a friction torque corresponding to 3kg, the first reel 43 provides a motion resistance corresponding to 28kg to the first tension member 50, and the second reel 44 provides a motion resistance corresponding to 28kg to the second tension member 51. For another example, if the two sets of tension adjusting mechanisms 42 each apply a friction torque corresponding to 5kg, the first reel 43 provides a motion resistance corresponding to 30kg to the first tension member 50, and the second reel 44 provides a motion resistance corresponding to 30kg to the second tension member 51.

In another embodiment, if the two sets of tension adjustment mechanisms 42 apply different preset friction torques, the driving force ultimately applied to the first reel 43 is different from the driving force applied to the second reel 44. For example, if the force intensity of the right hand of the user is greater than that of the left hand, and the left tension adjustment mechanism 42 applies a friction torque corresponding to 3kg and the right tension adjustment mechanism 42 applies a friction torque corresponding to 5kg, the first reel 43 provides a motion resistance corresponding to 28kg to the first tension member 50, and the second reel 44 provides a motion resistance corresponding to 30kg to the second tension member 51. For example, if the left tension adjustment mechanism 42 applies a friction torque corresponding to 7kg and the right tension adjustment mechanism 42 applies a friction torque corresponding to 3kg, the force intensity of the left hand of the user is greater than that of the right hand, the first reel 43 provides a motion resistance corresponding to 32kg to the first tension member 50, and the second reel 44 provides a motion resistance corresponding to 28kg to the second tension member 51.

Thus, before strength training, a user can pre-select a training mode (including a training object and training strength), for example, training the same strength of both hands or training different strengths of both hands, and then by setting the total output torque of the driving motor 41 and the preset friction torque applied by the two sets of tension adjusting mechanisms 42, various strength training matching with the fitness requirements of the user can be made, and the training application scenarios are wide.

In summary, the exercise mirror 100 provided by the present invention is provided with the tension adjusting mechanisms 42 on the two output shafts of the driving motor 41, respectively, and the two sets of tension adjusting mechanisms 42 can adjust the torque output by the driving motor 41 to the first reel 43 and the second reel 44, so as to achieve the grading of the motion resistance provided by the first reel 43 to the first tension member 50 and/or the motion resistance provided by the second reel 44 to the second tension member 51. Thus, the user can precisely grade the movement resistance by presetting the total output torque of the driving motor 41 and the preset friction torque applied by the two groups of tension adjusting mechanisms 42, and can make various strength exercises matching with the fitness requirements of the user.

In the present embodiment, the two sets of tension adjusting mechanisms 42 each include a servo motor 421, a transmission assembly 422, and a friction assembly 423.

The adjusting nut 4234 is drivingly connected with the transmission assembly 422, and is configured to move along the output shaft of the driving motor 41 upon receiving a driving torque from the transmission assembly 422, so as to adjust the pressing force between the friction member 4232 and the friction fixed disk 4231 and the friction movable disk 4233, respectively, and thereby apply a friction torque to the first reel 43 or the second reel 44.

In the present embodiment, the servo motor 421, the transmission assembly 422, the friction fixed disk 4231, the friction member 4232, the friction movable disk 4233 and the adjusting nut 4234 together form a stepless speed regulating structure.

During operation, each time the servo motor 421 rotates by a preset angle, the transmission assembly 422 applies a corresponding preset torque to the adjusting nut 4234. Under the action of the corresponding preset torque, the adjusting nut 4234 moves inwards or outwards along the output shaft of the driving motor 41 according to a preset stroke, so that the degree of squeezing of the friction movable disc 4233 by the adjusting nut 4234 is adjusted. Further, since the friction member 4232 is disposed between the friction fixing plate 4231 and the friction movable plate 4233, and the friction fixing plate 4231 and the friction movable plate 4233 cooperate to apply pressure to the friction member 4232 to adjust the friction torque applied to the first reel 43 and the second reel 44, the output torque of the first reel 43 or the second reel 44 is 1/2, which is the output torque of the drive motor 41 + the friction torque of the corresponding group tension adjustment mechanism 42, thereby achieving stepless torque adjustment.

Specifically, when the adjustment nut 4234 is moved inward along the output shaft of the drive motor 41 upon receiving the drive torque of the transmission assembly 422, the degree of pressing of the friction movable disk 4233 by the adjustment nut 4234 is increased, and the degree of pressing of the friction movable disk 4233 against the friction members 4232 is increased under the restriction of the friction fixed disk 4231, in other words, the pressing force between the friction members 4232 and the friction fixed disk 4231 and the friction movable disk 4233, respectively, becomes greater, increasing the friction torque applied to the first reel 43 and the second reel 44. The first reel 43 and the second reel 44 in the present embodiment are each capable of outputting greater motion resistance than the drive motor 41 alone would output to the first reel 43 and the second reel 44.

When the adjustment nut 4234 is moved outward along the output shaft of the drive motor 41 upon receiving the driving torque of the transmission assembly 422, the degree of pressing of the friction movable disk 4233 by the adjustment nut 4234 is reduced, and the degree of pressing of the friction movable disk 4233 against the friction members 4232 is reduced under the restriction of the friction fixed disk 4231, in other words, the pressing force between the friction members 4232 and the friction fixed disk 4231 and the friction movable disk 4233, respectively, is reduced, reducing the friction torque applied to the first reel 43 and the second reel 44. The first reel 43 and the second reel 44 in the present embodiment are still able to output a larger motion resistance than the drive motor 41 alone would output a motion resistance to the first reel 43 and the second reel 44.

In this way, the present embodiment precisely drives the adjusting nut 4234 to move on the output shaft of the driving motor 41 through the stepless speed regulating structure, specifically, the servo motor 421, and adjusts the degree of squeezing of the adjusting nut 4234 against the friction movable disk 4233, and further adjusts the degree of friction between the friction fixed disk 4231, the friction member 4232 and the friction movable disk 4233, so as to adjust the friction torque against the first reel 43 and the second reel 44, and achieve the highest one-sided movement resistance of the first tension member 50 and the second tension member 51. In addition, since the frictional torque applied to the first and

second reels

43 and 44 can be finely adjusted by controlling the driving motor 41, the exercise mirror 100 of the present embodiment can achieve precise grading of the exercise resistance, thereby satisfying different strength training needs of the user.

Referring to fig. 8, in a sub-embodiment, the tension adjusting mechanism 42 further includes a friction bearing 425, and the first reel 43 and the second reel 44 are each provided on both output shafts of the drive motor 41 through the friction bearing 425.

Referring to fig. 6, in one embodiment, the transmission assembly 422 includes a first timing pulley 422a and a timing belt 422 c. The first synchronous pulley 422a is in transmission connection with an output shaft of the servo motor 421, and the synchronous belt 422c is sleeved on the first synchronous pulley 422a and the adjusting nut 4234. Wherein, the transmission ratio of the first synchronous pulley 422a and the adjusting nut 4234 corresponds to the moving stroke of the adjusting nut 4234.

In one sub-embodiment, the threads on the output shaft of the drive motor 41 are high precision threads. The adjusting nut 4234 is a large-diameter nut with high-precision threads, and is provided with a high-precision threaded hole matched with the high-precision threads. Where high accuracy includes the micron scale or sub-micron scale.

In the embodiment, the movement resistance of the first tension member 50 and the second tension member 51 is adjusted by moving the large-diameter nut with high-precision threads and accurately adjusting the pressure applied to the friction member 4232.

In a specific operation process, when the servo motor 421 rotates by a preset angle, the first synchronous pulley 422a rotates by a corresponding preset angle, so that the adjusting nut 4234 moves at a level below a micron level or a micron level, the friction member 4232 is pressed by fine adjustment, and finally the movement resistance of the first tension member 50 and the second tension member 51 is adjusted at a gram level, so that stepless torque adjustment is realized.

It will be appreciated that the dimensions of the first timing pulley 422a and the adjustment nut 4234 can be specifically sized and geared to meet the output of the servomotor 421 corresponding to the travel of the adjustment nut 4234.

Referring to fig. 6, in other embodiments, the transmission assembly 422 further includes a second synchronous pulley 422b, the second synchronous pulley 422b is in synchronous transmission connection with the adjusting nut 4234, and the synchronous belt 422c is sleeved on the first synchronous pulley 422a and the second synchronous pulley 422 b. Wherein the transmission ratio of the first synchronous pulley 422a and the second synchronous pulley 422b corresponds to the moving stroke of the adjusting nut 4234.

In the present embodiment, the first timing pulley 422a transmits the driving torque of the servo motor 421 to the second timing pulley 422b, and the second timing pulley 422b is synchronized to the adjusting nut 4234.

It is understood that the size of the first synchronous pulley 422a and the size of the second synchronous pulley 422b can be designed to have a specific size and transmission ratio according to specific situations so that the output of the servo motor 421 corresponds to the moving stroke of the adjusting nut 4234.

In one sub-embodiment, the drive motor 41 comprises a dc brushless motor.

The present embodiment can make the torque dynamics of the driving motor 41 constant by precisely controlling the phase current of the dc brushless motor. Meanwhile, the strokes of the first tension member 50 and the second tension member 51 can be accurately controlled through a PID (proportion integration differentiation) adjusting method, so that the first tension member 50 and the second tension member 51 can reach the designated positions and lock the positions, the situation that the hands of a user shake the first tension member 50 or the second tension member 51 to hurt the user due to collision with the exercise mirror 100 is prevented, and the safety performance of the exercise mirror 100 is improved.

Referring to fig. 7 and 8, in one embodiment, the friction member 4232 includes an indexing ring 4232a, a plurality of indexing bearings 4232b and a plurality of elastic wheels 4232 c. The index ring 4232a is disposed between the friction fixed disk 4231 and the friction movable disk 4233, a plurality of index bearings 4232b are uniformly distributed along the circumferential direction of the index ring 4232a, and a plurality of elastic wheels 4232c are correspondingly disposed on the plurality of index bearings 4232 b.

The embodiment adopts the annular indexing ring 4232a to fix the elastic wheel 4232c, so that the running stability is improved. Meanwhile, the annular indexing ring 4232a is circumferentially and uniformly provided with a plurality of indexing bearings 4232b, and the plurality of indexing bearings 4232b can reduce the friction coefficient of the outer surfaces of the plurality of elastic wheels 4232c when pressed by the friction fixed disc 4231 and the friction movable disc 4233.

Further, in an actual exercise room, when a user exercises the exercise apparatus, parts of the components collide with each other or rub against each other to generate harsh noise, which seriously affects the hearing effect of the user.

In order to solve the above problems, the present embodiment can not only achieve accurate movement resistance classification by using the elastic wheel 4232c as the friction member 4232, but also extend the service life of the tension adjusting mechanism 42 due to the small friction between the elastic wheel 4232c and the friction fixed disk 4231 and the friction movable disk 4233, and more importantly, can achieve a mute effect, thereby improving the use effect of the user in practicing the exercise mirror 100 of the present embodiment.

In one sub-embodiment, the resilient wheel 4232c comprises a rubber wheel or a composite elastomer.

In this embodiment, the elastic wheel 4232c has high rigidity, can bear the pressure of the friction fixed disk 4231 and the friction movable disk 4233, and has a large noise reduction coefficient, so that it is possible to avoid harsh noise when the friction fixed disk 4231 and the friction movable disk 4233 press the friction fixed disk 4231 and the friction movable disk 4233. The rubber wheel or the composite elastomer in this embodiment all meet the above criteria.

Of course, it is understood that the rigidity standard and the noise reduction coefficient standard of the elastic wheel 4232c are set according to actual situations, for example, only a material with a high noise reduction coefficient is used, or a material with a low noise reduction coefficient is used, and other noise reduction devices are additionally configured to perform noise reduction, and are not particularly limited herein.

In one sub-embodiment, the indexing bearing 4232b comprises a needle bearing.

The friction coefficient of the needle bearing is smaller than that of the sliding bearing, the transmission efficiency is high, the needle bearing has higher mechanical performance and longer service life, and can bear radial load and axial load at the same time, so that the structure of the bearing support can be simplified, and the structural load can be reduced. In addition, because the inner clearance of the needle bearing is small, the processing precision of each part is high, and therefore the running precision is high, so that the fine adjustment of the movement resistance of the first tension piece 50 and the second tension piece 51 is realized, and further, the accurate movement resistance grading is realized.

Referring to fig. 9, in one embodiment, the elastic wheel 4232c includes a first pressing surface 4235, a second pressing surface 4236 and a pressing side surface 4237, the pressing side surface 4237 connects the first pressing surface 4235 and the second pressing surface 4236, and an included angle between the first pressing surface 4235 and/or the second pressing surface 4236 and a horizontal plane is an acute angle. The friction fixed disc 4231 and the friction movable disc 4233 are both provided with friction grooves 4238 matched with the elastic wheel 4232c in shape.

Referring to fig. 8, in the present embodiment, the pressing surfaces of the elastic wheel 4232c of the friction member 4232 and the friction fixed disk 4231 and the friction movable disk 4233 are a first pressing surface 4235 and a second pressing surface 4236. The extent of pressing of the friction member 4232 against the friction fixed disk 4231 and the friction movable disk 4233 is the sum of the extent of pressing of the first pressing surface 4235 and the second pressing surface 4236 of the plurality of elastic wheels 4232c on the index ring 4232a against the friction groove 4238.

Further, an included angle between the first pressing surface 4235 and the horizontal plane is an acute angle, and the second pressing surface 4236 is parallel to the horizontal plane; or the included angle between the second pressing surface 4236 and the horizontal plane is an acute angle, and the first pressing surface 4235 is parallel to the horizontal plane; alternatively, the included angle between the first pressing surface 4235 and the horizontal plane and the included angle between the second pressing surface 4236 and the horizontal plane are both acute angles.

It is understood that the distance that the elastic wheel 4232c enters the friction groove 4238 is positively correlated with the friction torque of the two, and the larger the distance that the elastic wheel 4232c enters the two friction grooves 4238, the larger the friction torque between the elastic wheel 4232c and the two friction grooves 4238.

In the embodiment, the pressing surfaces of the elastic wheel 4232c, the friction fixed disc 4231 and the friction movable disc 4233 are designed into inclined surfaces, so that the contact area between the elastic wheel 4232c and the friction fixed disc 4231 and the contact area between the elastic wheel 4232c and the friction movable disc 4233 can be increased, the adjustable stroke of the elastic wheel 4232c entering the friction groove 4238 is prolonged, and finer movement resistance grading is realized.

In a specific operation, for example, the servo motor 421 rotates forward by a predetermined angle, and the first synchronous pulley 422a rotates by a corresponding predetermined angle, so that the adjusting nut 4234 moves inward by a micrometer, and the distance between the elastic wheels 4232c of the friction member 4232 and the two friction grooves 4238 increases, the pressure between the friction member 4232 and the friction fixed disk 4231 and the friction movable disk 4233 respectively increases, and the friction torque applied to the first reel 43 and the second reel 44 increases.

Correspondingly, when the servo motor 421 reversely rotates by a predetermined angle, the first synchronous pulley 422a rotates by a corresponding predetermined angle to move the adjusting nut 4234 outward in a micrometer scale, so that the distance between the plurality of elastic wheels 4232c of the friction member 4232 and the two friction grooves 4238 is reduced, and the pressure between the friction member 4232 and the friction fixed disk 4231 and the friction movable disk 4233 is reduced, thereby reducing the friction torque applied to the first reel 43 and the second reel 44.

Therefore, the movement resistance of the first tension member 50 and the second tension member 51 is finally adjusted in the gram level by pressing the elastic wheel 4232c to be finely adjusted, so that stepless torque adjustment is realized.

In a sub-embodiment, the first and/or second

pressing surfaces

4235, 4236 are at an angle of 50 degrees to the horizontal.

The friction member 4232 in the above embodiment may adopt structures other than the structure of the index ring 4232a, the plurality of index bearings 4232b and the plurality of elastic wheels 4232c, for example, the structure of the friction plate 4232e and the friction disk, and the structure of the friction plate 4232e and the friction disk will be described in detail with reference to the drawings.

Referring to fig. 10 to 14, in one embodiment, the friction member 4232 further includes a fixed ring 4232d and a plurality of friction plates 4232e, the fixed ring 4232d is disposed between the friction fixed disc 4231 and the friction movable disc 4233, and the plurality of friction plates 4232e are uniformly distributed along a circumferential direction of the fixed ring 4232 d.

In the embodiment, the annular fixing ring 4232d is used for fixing the plurality of friction plates 4232e, so that the operation stability is improved. Meanwhile, a plurality of friction plates 4232e are uniformly distributed on the annular fixing ring 4232d in the circumferential direction.

In a specific operation, for example, the servo motor 421 rotates forward by a predetermined angle, and the first synchronous pulley 422a rotates by a corresponding predetermined angle, so that the adjusting nut 4234 moves inward by a micrometer, and the friction plates 4232e of the friction member 4232 are pressed against the friction fixed plate 4231 and the friction movable plate 4233 to increase the friction torque applied to the first reel 43 and the second reel 44.

Correspondingly, the servo motor 421 reversely rotates by a predetermined angle, and the first synchronous pulley 422a rotates by a corresponding predetermined angle to move the adjusting nut 4234 outward on a micrometer scale, so that the friction plates 4232e of the friction member 4232 are pressed against the friction fixed disk 4231 and the friction movable disk 4233 to a reduced degree, thereby reducing the friction torque applied to the first reel 43 and the second reel 44.

Therefore, the friction plate 4232e is pressed by fine adjustment, and finally the movement resistance of the first tension member 50 and the second tension member 51 is adjusted in gram level, so that stepless torque adjustment is realized.

Referring to fig. 3 and 5, in one embodiment, the exercise mirror 100 further includes a pressure sensing module 60, and the driving module 40 further includes a controller.

The pressure sensing module 60 is arranged on the moving loop of the first tension member 50 and the second tension member 51, and is used for acquiring the tension of the first tension member 50 and the second tension member 51 and sending the acquired result to the controller. The controller is disposed in the driving housing 45 and electrically connected to the driving motor 41 and the servo motor 421 respectively, for controlling the output torque of the driving motor 41 and the output torque of the servo motor 421 according to the collected result.

In this embodiment, the pressure sensing module 60 is used to collect the magnitudes of the tension forces of the first tension member 50 and the second tension member 51, so as to monitor the movement resistance of the driving module 40 exerted on the first tension member 50 and the second tension member 51, respectively. The controller judges whether the preset movement resistance is the same as the preset movement resistance according to the result acquired by the pressure sensing module 60, and if the preset movement resistance is the same as the preset movement resistance, the output torque of the driving motor 41 and the output torque of the servo motor 421 are continuously maintained; if the difference is not the same, the tension error is calculated, and the output torque of the driving motor and the output torque of the servo motor are further adjusted, so that the same movement resistance as the preset movement resistance is applied to the first tension member 50 and/or the second tension member 51.

Specifically, since the guide assemblies are two sets, please refer to fig. 15 and 16, the pressure sensing module 60 includes a fixed frame 61, a double force bearing assembly 62 and a double pressure sensor 63.

As shown in fig. 3, the fixing frame 61 is provided at the center above the main body frame 10.

As shown in fig. 15 and 16, one of the force bearing assemblies 62 is disposed at the left side of the fixed frame 61 and is used for penetrating the first tension member 50 together with the first guide assembly 31, so as to change the tension direction of the first tension member 50. Wherein, the force bearing component 62 comprises a guide plate and a fixed pulley arranged on the guide plate. The pressure sensor 63 is arranged on the force bearing component 62 and used for acquiring the tension of the first tension member 50 and sending the acquired result to the controller. The controller then determines whether to adjust the output torque of the drive motor 41 and the output torque of the servo motor 421 according to the acquisition result.

Similarly, the other force bearing component 62 is arranged on the right side of the fixed frame 61 and is used for penetrating the first tension member 50 together with the first guide component 31, so that the tension direction of the first tension member 50 is changed. Wherein, the force bearing component 62 comprises a guide plate and a fixed pulley arranged on the guide plate. The pressure sensor 63 is arranged on the force bearing component 62 and used for acquiring the tension of the first tension member 50 and sending the acquired result to the controller. The controller then determines whether to adjust the output torque of the drive motor 41 and the output torque of the servo motor 421 according to the acquisition result.

Referring to fig. 3, 4 and 17, in one embodiment, the first guiding assembly 31 includes a first rotating arm 311, a first sliding member 312, a first gear adjusting member 313 and a plurality of first fixed pulleys 314. The first swing arm 311 is disposed on the left side of the main body frame 10 along the height direction of the main body frame 10, and is provided with a plurality of first position limiting holes 315. The first sliding member 312 is disposed on the first radial arm 311, and the first gear adjusting member 313 is disposed on the first sliding member 312 and is used to be limited on any one of the first gear limiting holes 315. At least one first fixed pulley 314 is fixedly installed on the top of the first radial arm 311, at least one first fixed pulley 314 is fixedly installed on the first sliding member 312, and the plurality of first fixed pulleys 314 are guided in different directions and are used together to guide the first tension member 50 to the outside of the body frame 10.

The second guiding assembly 32 includes a second radial arm 321, a second sliding member 322, a second gear adjusting member 323, and a plurality of second fixed pulleys 324. The second swing arm 321 is disposed on the right side of the main body frame 10 along the height direction of the main body frame 10, and is provided with a plurality of second gear position limiting holes 325. The second sliding member 322 is disposed through the second radial arm 321, and the second gear adjusting member 323 is disposed on the second sliding member 322 and is used to be limited on any one of the second gear limiting holes 325.

In the present embodiment, the plurality of first fixed pulleys 314 and the plurality of second fixed pulleys 324 are used for passing through the corresponding tension member, so as to change the tension direction of the tension member.

Specifically, as shown in fig. 17, at least one second fixed pulley 324 is fixedly installed on the top of the second radial arm 321 for guiding the second pulling member 51, which is extended out from the main body frame 10, to a direction parallel to the second radial arm 321. At least one second fixed pulley 324 is fixedly installed on the second sliding member 322 for guiding the second pulling member 51 parallel to the second radial arm 321 to the outside of the exercise bike 100, so that the user can hold the pulling ring or pulling ring on the second pulling member 51.

Similarly, at least one first fixed pulley 314 is fixedly installed on the top of the first radial arm 311 for guiding the first pulling member 50 extending out from the main body frame 10 to a direction parallel to the first radial arm 311. At least one first fixed pulley 314 is fixedly installed on the first sliding member 312 for guiding the first pulling member 50 parallel to the first radial arm 311 to the outside of the exercise mirror 100, so that the user can hold the pulling ring or pulling ring on the first pulling member 50.

In addition, the first slider 312 can also realize multi-shift adjustment of the first tension member 50 on the first radial arm 311, and the second slider 322 can also realize multi-shift adjustment of the second tension member 51 on the second radial arm 321.

Specifically, the first gear adjuster 313 is a tab that can be inserted into any one of the first gear limiting holes 315 to limit the position of the first sliding member 312 on the first radial arm 311; when the position of the first sliding member 312 needs to be changed, the first gear adjusting member 313 is pulled out of the first gear limiting hole 315 and then inserted into another first gear limiting hole 315, so as to change the stroke of the first tension member 50 in the height direction of the main body bracket 10. Thus, by changing the position of the first slider 312 on the first radial arm 311, various modes of exercise can be achieved.

Similarly, the second gear adjusting element 323 is a pull buckle, and can be inserted into any one of the second gear limiting holes 325 to limit the position of the second sliding element 322 on the second radial arm 321; when the position of the second sliding member 322 needs to be changed, the second gear adjusting member 323 is pulled out of the second gear limiting hole 325 and then inserted into another second gear limiting hole 325, so as to realize the stroke change of the second tension member 51 in the height direction of the main body bracket 10. Thus, by changing the position of the second slider 322 on the second radial arm 321, various modes of exercise can be achieved.

With continued reference to fig. 1-5, in one embodiment, the first guiding assembly 31 further includes a first leg 316 and a third fixed pulley 317. The first leg 316 is detachably coupled to a bottom side of the main body frame 10 and extends toward a front side of the main body frame 10. The third fixed pulley 317 is disposed at one end of the first leg 316 far from the bottom of the main body support 10, and is used for penetrating the first tension member 50 to change the tension direction of the first tension member 50.

Second guide assembly 32 also includes a second leg 326 and a fourth fixed sheave 327. The second leg 326 is detachably connected to the other side of the bottom of the main body frame 10 and extends toward the front of the main body frame 10. The fourth fixed pulley 327 is disposed at an end of the second leg 326 far away from the bottom of the main body frame 10, and is used for penetrating the second tension member 51 to change the tension direction of the second tension member 51.

In the above embodiment, the first slider 312 can move to the bottom of the first radial arm 311 at most, and the second slider 322 can move to the bottom of the second radial arm 321 at most, which cannot match the user to perform the strength training of lifting upward.

In the embodiment, the first leg 316 and the third fixed pulley 317 are used for changing the pulling direction of the first pulling member 50, so that the first pulling member 50 can be pulled upwards after passing through the third fixed pulley 317. Similarly, the second leg 326 and the fourth fixed pulley 327 are used to change the pulling direction of the second pulling member 51, so that the second pulling member 51 can be pulled upward after passing through the third fixed pulley 317.

Thus, by adding the first leg 316, the third fixed pulley 317, the second leg 326 and the fourth fixed pulley 327 to the bottom of the main body frame 10, it is possible to provide a user with various modes of exercise.

Referring to fig. 1 to 5, in one embodiment, the first swing arm 311 and the second swing arm 321 can be folded toward the back of the main body frame 10 relative to the main body frame 10.

Compared with the existing exercise mirror, the first radial arm 311 and the second radial arm 321 which are large in volume are installed on the two sides of the main body support 10 in the embodiment, so that the original volume of the exercise mirror 100 can be increased.

In order to solve the above problem, the present embodiment further designs the first radial arm 311 and the second radial arm 321 to be foldable toward the back of the main body support 10 through a smart folding design, and when the exercise mirror 100 is not used, the first radial arm 311 and the second radial arm 321 can be folded toward the back of the main body support 10 from the left and right sides of the main body support 10. As shown in fig. 3, the first swing arm 311 has been folded to the back of the main body frame 10, and the second swing arm 321 is held at the side of the main body frame 10. Thus, the floor space of the fitness mirror 100 is reduced, and the household strength training is easy to realize.

Specifically, as shown in fig. 17, in a sub-embodiment, each of the first guide assembly 31 and the second guide assembly 32 further includes a rotary seat 33 and a rotary seat bearing 34, and the main body support 10 is provided with the moment arm rotating shaft 11. The rotary seats 33 are respectively fixedly installed at opposite ends of the first swing arm 311 and opposite ends of the second swing arm 321. The swivel bearing 34 is disposed on the swivel base 33 and sleeved on the arm rotation axis 11, so that the first swing arm 311 and the second swing arm 321 can rotate around the corresponding arm rotation axis 11 relative to the main body frame 10.

When the user needs to perform strength training, the first swing arm 311 and the second swing arm 321 are rotated to the left and right sides of the main body support 10 around the corresponding arm rotation shafts 11 for the user to perform tension training. When the user does not need to do strength training, the first radial arm 311 and the second radial arm 321 are rotated to the back of the main body support 10 around the corresponding moment arm rotating shaft 11, so that the first radial arm 311 and the second radial arm 321 can be folded and stored, and the whole floor area of the fitness mirror 100 is reduced; meanwhile, the beauty of the fitness mirror 100 is improved after the fitness mirror 100 is folded and stored, so that the fitness mirror 100 can be used as a common mirror 22.

In a specific scenario, taking the first tension member 50 as an example, when the first tension member 50 is pulled outwards, since the first reel 43 is mainly driven by the first tension member 50, the driving motor 41 and the servo motor 421 rotate against the preset rotation direction, and at this time, the rotor rotates against the magnetic force lines, i.e., the rotor rotates reversely, the relative movement between the rotor and the magnetic force lines is large, and the rotor cuts the magnetic force lines to a large extent. According to the law of electromagnetism, a large counter electromotive force is generated inside the driving motor 41 and the servo motor 421, and a large induced current is generated, so that the movement resistance of the driving motor 41 and the servo motor 421 on the first tension member 50 is further increased, and therefore the movement resistance of the driving motor 41 and the servo motor 421 on the first tension member 50 is actually larger than the preset movement resistance.

When the user releases the first pulling force piece 50, the first pulling force piece 50 can retract, in the retracting process, as the first reel 43 is mainly driven by the driving motor 41 and the servo motor 421, the driving motor 41 and the servo motor 421 rotate along the preset rotating direction, at the moment, the rotor rotates along the direction of the magnetic force lines, namely, the rotor rotates forwards, the relative movement between the rotor and the magnetic force lines is small, and the degree of cutting the magnetic force lines by the rotor is small. According to the law of electromagnetism, the driving motor 41 and the servo motor 421 generate a small back electromotive force, and thus a small induced current, so that the movement resistance of the driving motor 41 and the servo motor 421 exerted on the first tension member 50 is actually slightly smaller than the preset movement resistance.

It can be seen that, in the process of drawing and returning, the driving motor 41 and the servo motor 421 do not exert the same motion resistance on the first tension member 50 and the second tension member 51, that is, the pulling moment and the returning moment are not consistent, which affects the user to perform a strict strength training.

In order to solve the above problem, referring to fig. 3, in one embodiment, the exercise mirror 100 further includes a compensation module 80, and the compensation module 80 is disposed on the moving loop of the first tension member 50 and the second tension member 51 and is used for performing tension compensation on the first tension member 50 and the second tension member 51.

Specifically, referring to fig. 18 to 21, the compensation module 80 includes a first compensation mechanism 81 and a second compensation mechanism 82.

The first compensation mechanism 81 comprises a first supporting component 811 and a first swing angle pressing component 812, the first supporting component 811 and the first swing angle pressing component 812 are oppositely arranged on the main body bracket 10, and the first swing angle pressing component 812 is used for matching with the first supporting component 811 to unidirectionally press the first tension member 50.

The second compensation mechanism 82 includes a second support component 821 and a second swing angle pressing component 822, the second support component 821 and the second swing angle pressing component 822 are oppositely disposed on the main body support 10, and the second swing angle pressing component 822 is used for cooperating with the second support component 821 to press the second pulling member 51 in a single direction.

In the embodiment, the first swing angle pressing assembly 812 is matched with the first support assembly 811 to unidirectionally press the first tension member 50, and the second swing angle pressing assembly 822 is matched with the second support assembly 821 to unidirectionally press the second tension member 51, so that the first tension member 50 and the second tension member 51 are respectively subjected to return tension compensation.

Specifically, when the first tension member 50 is pulled out, the first swing angle pressing assembly 812 and the first supporting assembly 811 do not perform unidirectional pressing on the first tension member 50, and the tension experienced by the user is the movement resistance applied to the first tension member 50 by the driving motor 41 and the servo motor 421. When the first tension member 50 returns, the first swing angle pressing assembly 812 cooperates with the first supporting assembly 811 to perform unidirectional pressing on the first tension member 50, so as to increase the resistance when the first tension member 50 retracts, which is superimposed on the motion resistance exerted on the first tension member 50 by the driving motor 41 and the servo motor 421, so that the user experiences that the motion resistance of the first tension member 50 during the return stroke is substantially consistent with the motion resistance of the outward pulling.

Illustratively, it is assumed that the preset current applied to the driving motor 41 and the servo motor 421 is 3A in order to keep the rotation speeds of the driving motor 41 and the servo motor 421 constant. When the first pulling force member 50 is pulled outwards, the induced current generated by the driving motor 41 and the servo motor 421 is 1A, and the resistance of 1A is superimposed on the movement resistance of the preset current 3A, so that the pulling force experienced by the user is the movement resistance corresponding to 4A. When the first tension member 50 returns, the first swing angle pressing component 812 and the first supporting component 811 perform unidirectional pressing on the first tension member 50, and generate a movement resistance corresponding to approximately 1A, and the resistance of 1A is superposed on the movement resistance of the preset current 3A, so that the user experiences the movement resistance corresponding to 4A as well, and the pull moment and the return moment are consistent.

Similarly, when the second pulling force member 51 is pulled outwards, the second swing angle pressing assembly 822 and the second supporting assembly 821 do not perform unidirectional pressing on the second pulling force member 51, and the pulling force experienced by the user is the movement resistance applied to the second pulling force member 51 by the driving motor 41 and the servo motor 421. When the second tension member 51 returns, the second swing angle pressing assembly 822 cooperates with the second support assembly 821 to perform unidirectional pressing on the second tension member 51, so as to increase the retraction resistance of the second tension member 51, which is superimposed on the movement resistance of the driving motor 41 and the servo motor 421 applied to the second tension member 51, so that the user experiences that the movement resistance of the second tension member 51 returning and the movement resistance of the outward pulling are substantially the same. Therefore, the requirement of the user for strict strength training is met.

The magnitude of the induced current is related to the degree of magnetic line cutting (related to the rotation speed of the rotor, the magnetic field strength, etc.), that is, the magnitude of the induced current changes every time the rotor is pulled out. For example, when the first and second pulling

members

50 and 51 are pulled outward by a user, the greater the rotation speeds of the driving motor 41 and the servo motor 421, the greater the induced current generated, and the induced current magnitude of 1A above is only exemplified.

In summary, in the fitness mirror 100 provided by the invention, the compensation module 80 is additionally arranged on the moving loops of the first tension member 50 and the second tension member 51, and the compensation module 80 can respectively perform unidirectional compression on the first tension member 50 and the second tension member 51, so that the first tension member 50 and the second tension member 51 are not compressed when being pulled out, but are compressed when returning, thereby realizing return tension compensation, and enabling the pull moment and the return moment to be consistent, thereby providing accurate strength training for a user.

Referring to fig. 18 to 21, in one embodiment, each of the first supporting component 811 and the second supporting component 821 includes a fixing shaft 830, a supporting bearing 831 and a roller 832, the fixing shaft 830 is disposed on the main body frame 10, and the roller 832 is sleeved on the corresponding fixing shaft 830 through the supporting bearing 831.

In this embodiment, the roller 832 can rotate around the fixed shaft 830, so that the first pulling member 50 and the second pulling member 51 are not jammed during outward pulling and backward pulling. Meanwhile, under the radial limitation of the fixed shaft 830, the roller 832 may cooperate with the first and second swing

angle pressing assemblies

812 and 822 to press the first and

second tension members

50 and 51 together to compensate for the resistance of the return stroke.

Referring to fig. 19 and 20, in one embodiment, each of the first supporting component 811 and the second supporting component 821 further includes two supporting and limiting plates 833 respectively, and the two supporting and limiting plates 833 are disposed on the main body frame 10 and are respectively used for axially limiting the corresponding roller 832.

It will be appreciated that the rollers 832 are easily slid out of the ends of the fixed shaft 830 when rolling without limitation.

In this embodiment, the supporting stopper plates 833 are respectively disposed at both axial sides of the roller 832 to restrict axial displacement of the roller 832 during rolling, thereby preventing the roller 832 from slipping out of both ends of the fixed shaft 830.

Referring to fig. 19 to 20, in one embodiment, the first swing angle pressing assembly 812 and the second swing angle pressing assembly 822 respectively include a swing angle fixing plate 840, a swing angle rotating shaft 841, a compensation motor 842, and a swing angle moving plate 843.

The swing angle fixing plate 840 is disposed on the body frame 10 and inclined upward with respect to a horizontal line, and the first and second support assemblies 811 and 821 are each disposed above the corresponding swing angle fixing plate 840.

The swing angle rotating shaft 841 and the compensation motor 842 are respectively arranged at two ends of the swing angle fixing plate 840, the swing angle movable plate 843 is relatively rotatably arranged with the swing angle fixing plate 840 through the swing angle rotating shaft 841, an output through hole 843a is further formed on the swing angle movable plate 843, and an output shaft of the compensation motor 842 penetrates out of the output through hole 843a and is respectively opposite to the corresponding first supporting component 811 or the corresponding second supporting component 821.

In the present embodiment, the first swing angle pressing assembly 812 and the second swing angle pressing assembly 822 are both swing angle structures and are inclined upward with respect to the horizontal line.

The swing angle fixing plate 840 is installed on the main body bracket 10, and is used to install the compensation motor 842 and the swing angle moving plate 843.

The compensation motor 842 is disposed on the swing angle fixing plate 840 at a position close to the first support assembly 811 or the second support assembly 821 for applying a return resistance to the tension member sandwiched between the output end of the compensation motor 842 and the first support assembly 811 or the second support assembly 821.

Specifically, when the first tension member 50 is pulled out, the driving motor 41 and the servo motor 421 apply a movement resistance to the first tension member 50, and the compensation motor 842 is not operated, and the movement resistance of the first tension member 50 is actually greater than the preset movement resistance. When the first tension member 50 returns, the driving motor 41 and the servo motor 421 apply a movement resistance to the first tension member 50, and the compensation motor 842 operates and cooperates with the roller 832 of the first support assembly 811 to unidirectionally press the first tension member 50, so as to increase a resistance when the first tension member 50 retracts, which is superimposed on the movement resistance applied to the first tension member 50 by the driving motor 41 and the servo motor 421, so that a user experiences that the movement resistance of the same first tension member 50 when returning is substantially consistent with the movement resistance of pulling.

Similarly, when the second pulling member 51 is pulled outwards, the driving motor 41 and the servo motor 421 apply a movement resistance to the second pulling member 51, and the compensation motor 842 does not operate, and the movement resistance of the second pulling member 51 is actually greater than the preset movement resistance. When the second pulling force member 51 returns, the driving motor 41 and the servo motor 421 apply a movement resistance to the second pulling force member 51, and the compensation motor 842 operates and cooperates with the roller 832 of the second support assembly 821 to perform unidirectional compression on the second pulling force member 51, so as to increase a resistance when the second pulling force member 51 retracts, which is superposed with the movement resistance applied to the second pulling force member 51 by the driving motor 41 and the servo motor 421, so that a user experiences that the movement resistance of the same second pulling force member 51 for returning is substantially consistent with the movement resistance of pulling.

Further, the current of the compensation motor 842 can be set to generate a return resistance to the first tension member 50 and the second tension member 51, so as to compensate the motion resistance corresponding to the currents induced by the driving motor 41 and the servo motor 421.

For example, it is assumed that the preset current applied to the driving motor 41 and the servo motor 421 is 3A. When the first pulling member 50 is pulled outwards, the compensation motor 842 does not operate, the induced current generated by the operation of the driving motor 41 and the servo motor 421 is 1A, and the resistance of 1A is superimposed on the movement resistance of the preset current 3A, so that the user experiences the movement resistance corresponding to the pull-out resistance of 4A. When the first pulling member 50 returns, the compensation motor 842 operates and cooperates with the roller 832 to generate a motion resistance corresponding to approximately 1A, and the resistance of 1A is superposed on the motion resistance of the preset current 3A of the driving motor 41 and the servo motor 421, so that the user experiences the motion resistance corresponding to the return resistance of 4A, and the pulling moment and the return moment are consistent.

It can be understood that, since the magnitude of the induced current in each pulling-out process changes, when the change of the induced current in each pulling-out process is large, the magnitude of the induced current in each pulling-out process can be measured, so as to adjust the magnitude of the current of the compensation motor 842 in the return process; the current of the compensation motor 842 can be a fixed value (e.g., set to 1A) when the change of the induced current during each pull-out is small, so that the magnitude of the induced current does not need to be measured each time, and thus the magnitude of the current of the compensation motor 842 during the return stroke can be adjusted, and the pull-out torque and the pull-back torque are substantially the same.

In addition, since the swing angle fixing plate 840 is inclined upward with respect to the horizontal line, the swing angle moving plate 843 is also inclined upward with respect to the horizontal line. Thus, during the return stroke, when the compensation motor 842 is operated, the swing angle movable plate 843 applies a return stroke resistance to the first tension member 50 or the second tension member 51; meanwhile, the swing angle movable plate 843 can also rotate relative to the swing angle fixing plate 840 around the swing angle rotating shaft 841, so that the swing angle movable plate 843 cannot press the first tension member 50 or the second tension member 51 when being pulled outwards, and the effect of preventing the clamping stagnation of the pulling outwards is achieved.

Referring to fig. 19 to fig. 21, in an embodiment, each of the first swing angle pressing assembly 812 and the second swing angle pressing assembly 822 further includes a one-way bearing 844, an output shaft of the compensation motor 842 penetrates through the output through hole 843a and is in transmission connection with the one-way bearing 844, and the one-way bearing 844 is respectively opposite to the corresponding first supporting assembly 811 or the second supporting assembly 821.

In this embodiment, the output shafts of the compensation motors 842 of the first swing angle pressing assembly 812 and the second swing angle pressing assembly 822 are respectively provided with a one-way bearing 844.

When the first pulling member 50 or the second pulling member 51 is pulled out, the compensation motor 842 is not operated, and the first pulling member 50 or the second pulling member 51 directly drives the one-way bearing 844 to rotate, at this time, the one-way bearing 844 is in the direction of tangential resultant force at the contact point. When the first pulling member 50 or the second pulling member 51 returns, the first pulling member 50 or the second pulling member 51 also drives the one-way bearing 844 to rotate, but at this time, to realize the return pulling force compensation, the compensation motor 842 operates to drive the one-way bearing 844 to rotate reversely, so that the one-way bearing 844 is downward in the direction of tangential resultant force at the contact point.

In this embodiment, the one-way bearing 844 is installed on the output shaft of the compensation motor 842, so that no clamping stagnation occurs when the first support assembly 811 or the second support assembly 821 is pulled out or returned.

Referring to fig. 19 to 21, in one embodiment, each of the first and second swing

angle pressing assemblies

812 and 822 further includes a limiting post 845, the limiting post 845 is fixedly disposed on the swing angle fixing plate 840, a limiting through hole 843b is disposed on the swing angle movable plate 843, and the limiting post 845 penetrates through the limiting through hole 843 b.

It can be appreciated that when the compensation motor 842 is operated, the compensation motor 842 applies a torque to the swing angle movable plate 843 such that the swing angle movable plate 843 is offset.

In order to avoid the situation that the offset position of the swing angle movable plate 843 is large, and the output shaft of the compensation motor 842 cannot be directly opposite to the corresponding first supporting component 811 or the corresponding second supporting component 821, the limiting column 845 is added in the embodiment, when the swing angle movable plate 843 is offset, the limiting through hole 843b is also offset accordingly, at this time, under the limiting action of the limiting column 845, the swing angle movable plate 843 is not offset any more, and the output shaft of the compensation motor 842 is always directly opposite to the corresponding first supporting component 811 or the corresponding second supporting component 821.

Referring to fig. 19, in one embodiment, the swing angle fixing plate 840 and the swing angle movable plate 843 are both rounded rectangles.

In this embodiment, the swing angle fixing plate 840 and the swing angle movable plate 843 are designed to be rounded rectangles, so as to avoid the clamping stagnation phenomenon caused by hooking the first tension member 50 or the second tension member 51 when the edges of the swing angle fixing plate 840 and the swing angle movable plate 843 are right angles.

Referring to fig. 18 to 21, in one embodiment, each of the first compensation mechanism 81 and the second compensation mechanism 82 further includes two compensation position limiting plates 85, the two compensation position limiting plates 85 are respectively disposed on two opposite sides of the first compensation mechanism 81 or two opposite sides of the second compensation mechanism 82, and both have a position limiting through hole 851, and the two position limiting through holes 851 are opposite and are used for penetrating the first tension member 50 or the second tension member 51.

In this embodiment, two opposite sides of the first compensation mechanism 81 and two opposite sides of the second compensation mechanism 82 are respectively provided with a compensation limiting plate 85, and each compensation limiting plate 85 is provided with a limiting through hole 851.

When the first tension member 50 is clamped between the first supporting component 811 and the first swing angle pressing component 812, the two opposite limiting through holes 851 limit the two sides of the first tension member 50 respectively, so that the first tension member 50 is not easy to be separated from the clamping of the first supporting component 811 and the first swing angle pressing component 812, and the reliability of unidirectional pressing is improved.

Similarly, when the second pulling force member 51 is clamped between the second supporting component 821 and the second swing angle pressing component 822, the two opposite limiting through holes 851 limit the two sides of the second pulling force member 51 respectively, so that the second pulling force member 51 is not easy to be separated from the clamping of the second supporting component 821 and the second swing angle pressing component 822, and the reliability of unidirectional pressing is improved.

In addition, the present embodiment can also accurately calculate the pulling-out strokes of the first pulling force member 50 and the second pulling force member 51 corresponding to a whole set of strength training according to the total power consumed by the driving motor 41 and the total power consumed by the two sets of pulling force adjusting mechanisms 42, so as to calculate the calories consumed by the user in the whole set of strength training. Compared with the prior art, the calorie calculation method provided by the embodiment of the invention can accurately calculate the calorie consumed by the user.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
