Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described and illustrated below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden on the person of ordinary skill in the art based on the embodiments provided herein, are intended to be within the scope of the present application.

As shown in fig. 1 to 16, the present embodiment provides a deformable saddle conforming to the ergonomics, which includes a base mounting portion 100 and a seat body 300 mounted on the base mounting portion 100 through a frame unit 200, wherein a support tube 110 is fixedly disposed on a lower end surface of the base mounting portion 100, and the support tube 110 is inserted into a frame of a bicycle, the frame unit 200 includes a pair of frame bodies 210 arranged in a left-right mirror image manner, and a middle portion of the frame bodies 210 is mounted on the base mounting portion 100, and front and rear ends of the frame bodies 210 are mounted on the seat body 300, thereby forming the saddle.

In other words, the frame unit 200 is combined with the seat body 300 as a seat body, and the seat body is combined with the base mounting portion 100 through the middle portion of the frame body 210, and the saddle body is combined with the frame of the bicycle through the support tube 110 of the lower end surface of the base mounting portion 100.

Specifically, the base 300 includes a body unit 310 to support the body weight of the user; the front end of the bottom of the body unit 310 is fixedly provided with a front mounting block 320, the rear end of the bottom of the body unit 310 is fixedly provided with a pair of rear mounting blocks 330, the front ends of the pair of skeleton bodies 210 are all mounted in the front mounting blocks 320, and the rear ends of the pair of skeleton bodies 210 are respectively mounted in the pair of rear mounting blocks 330.

It should be noted that, in order to facilitate the assembly of the framework 210 with the base mounting portion 100 and the base 300, the framework 210 includes a middle horizontal section 211, a front end bending portion 212 located at one end of the middle horizontal section 211, and a rear end bending portion 213 located at the other end of the middle horizontal section 211, where the front end bending portion 212 is bent upward inside, and the rear end bending portion 213 is bent upward outside to adapt to the overall structure of the base 300.

It will be appreciated that in conventional bicycle saddles, the skeletal unit 200 is in a rigid configuration and the overall configuration of the body unit 310 of the seat body 300 is not deformed. However, the clamping force of the legs to the saddle becomes large at a specific moment during riding, particularly when the body is straightened or slightly leaned backward, resulting in increased compression of the saddle 200 to a part of the human body, giving a sense of discomfort.

In order to eliminate the above-mentioned drawbacks, the deformable saddle of the present embodiment is configured such that the body unit 310 is provided with a wide slit 311 in the middle, and the front ends of the wide slit 311 are formed into the thin waist portions 312 of the body unit 310, whereby the body unit 310 is bent inward when the saddle is clamped by the legs; accordingly, the frame body 210 is rotatably installed in the base installation part 100.

In other words, the front and rear ends of the wide seam 311 are respectively provided with the front coupling piece 313 and the rear coupling piece 314, and the front coupling piece 313 and the rear coupling piece 314 are structurally weakened members, so that the body unit 310 can be bent and deformed inward. The base mounting part 100 is provided with hinge mounting holes 101 penetrating front and rear, and a middle horizontal section 211 of the skeleton body 210 is rotatably mounted in the hinge mounting holes 101.

The fixed shaft 120 is further fixedly disposed above the base mounting portion 100, the inner pipe unit 400 is fixedly disposed on opposite sides of the pair of rear mounting blocks 330, the outer pipe unit 500 is hinged on the fixed shaft 120, and the inner pipe unit 400 can stretch and retract with respect to the outer pipe unit 500, in which case the inner pipe unit 400 can stretch and retract with respect to the outer pipe unit 500, and in which case the inner pipe unit 400 cannot stretch and retract with respect to the outer pipe unit 500.

In this way, when the clamping force of the user's legs against the saddle increases, the body unit 310 is forced to deform inward, and the pair of frame bodies 210 swings inward about the middle horizontal section 211 as a rotation fulcrum, respectively, and a force is generated to retract the inner pipe body unit 400 relative to the outer pipe body unit 500. In one case, the inner tube body unit 400 can be contracted relative to the outer tube body unit 500, and the body unit 310 is deformed inward, relieving the partial pressure of the saddle on the human body; in another case, as the body unit 310 is deformed, the clamping force of the legs to the saddle becomes smaller, and at this time, the inner tube unit 400 cannot be expanded and contracted with respect to the outer tube unit 500, so that the body unit 310 is in the most comfortable form for the human body.

Through the above arrangement, when the clamping force of the user's legs to the saddle is increased, the body unit 310 is naturally stressed to generate inward deformation, and the inner pipe body unit 400 can be contracted relative to the outer pipe body unit 500, thus relieving the partial compression of the saddle to the human body; as the body unit 310 is deformed, the clamping force of the legs to the saddle naturally becomes small, and the inner pipe body unit 400 cannot be extended and contracted with respect to the outer pipe body unit 500, so that the body unit 310 automatically stops being deformed and is in a most comfortable form for the human body. The whole deformation process of the body unit 310 is unconsciously adjusted in the riding process of the user, and is always in the most comfortable form, so that the body unit is in accordance with human engineering, and the use experience is greatly improved.

In other words, the side of the inner pipe unit 400 remote from the outer pipe unit 500 is provided with the first flange 410 so that the inner pipe unit 400 is fixedly mounted to the rear mounting block 330; the side of the outer pipe unit 500 remote from the inner pipe unit 400 is fixedly provided with a second flange 510, and the side of the second flange 510 remote from the inner pipe unit 400 is provided with a hinge ring 511 matched with the fixed shaft 120 so that the outer pipe unit 500 is rotatably installed to the fixed shaft 120.

Specifically, the end surface of the inner pipe body unit 400 facing the outer pipe body unit 500 extends outwards to form a rectangular plugging portion 420, the end surface of the outer pipe body unit 500 facing the inner pipe body unit 400 is provided with a rectangular plugging hole 520, and the rectangular plugging hole 520 is matched with the rectangular plugging portion 420, so that the inner pipe body unit 400 and the outer pipe body unit 500 can stretch relatively. Wherein, a side wall of the rectangular plugging hole 520 is provided with a plurality of tooth grooves 521 which are continuously arranged, a side surface of the rectangular plugging portion 420 is provided with elastic teeth 430, the elastic teeth 430 are matched with the tooth grooves 521, and the number of the teeth of the elastic teeth 430 is smaller than that of the tooth grooves 521.

In this way, when the clamping force of the user's legs to the saddle increases, a force is generated that the inner pipe body unit 400 contracts with respect to the outer pipe body unit 500. In one case, the elastic teeth 430 can be fully contracted, continuously from one tooth slot 521 to the next tooth slot 521, so that the inner pipe body unit 400 can be contracted with respect to the outer pipe body unit 500; in another case, the clamping force of the both legs to the saddle becomes small, the elastic teeth 430 cannot be fully contracted, the elastic teeth 430 are held in one of the tooth grooves 521, and the inner pipe body unit 400 cannot be expanded and contracted with respect to the outer pipe body unit 500.

Through the above arrangement, when the clamping force of the user's legs to the saddle is increased, the body unit 310 is naturally stressed to generate inward deformation, the elastic teeth 430 can be completely contracted, and the compression of the saddle to the local part of the human body is relieved from one tooth slot 521 to the next tooth slot 521 continuously; as the body unit 310 is deformed, the clamping force of the legs to the saddle naturally becomes small, the elastic teeth 430 cannot be completely contracted, and the elastic teeth 430 are held in one of the tooth grooves 521, so that the body unit 310 automatically stops being deformed and is in the most comfortable form for the human body.

In this embodiment, a rectangular stepped hole 421 is formed in one side of the rectangular plugging portion 420, the elastic teeth 430 include a toothed plate 431 and a plurality of teeth 432 fixedly disposed on an upper end surface of the toothed plate 431, the toothed plate 431 is located at a small diameter portion of the rectangular stepped hole 421, a slidable guide plate 440 is disposed in a large diameter portion of the rectangular stepped hole 421, and a lower end of the toothed plate 431 is detachably connected with an upper end of the guide plate 440. Thus, the guide plate 440 slides up and down in the large diameter portion of the rectangular stepped hole 421 so that the elastic teeth 430 can be extended and also retracted into the rectangular stepped hole 421.

For elastic expansion and contraction, a configuration cavity 422 is further formed in the rectangular plug-in part 420, and an elastic expansion plate 450 is slidably arranged in the configuration cavity 422; a spring element 460 is also disposed within the deployment chamber 422, and the spring element 460 is positioned below the resilient extension plate 450 to apply a resilient force to the resilient extension plate 450; an action coupling block 470 is also disposed in the deployment chamber 422, and the action coupling block 470 is located above the elastic expansion plate 450 to achieve an action coupling of the elastic teeth 430 with the elastic expansion plate 450. Thus, the elastic teeth 430 operatively coupled to the elastic expansion plate 450 can elastically expand and contract by the spring element 460 acting on the elastic expansion plate 450.

The action coupling block 470 includes a main body 471 and a guide connection portion 472 disposed at one side of the main body 471, wherein the guide connection portion 472 penetrates through the rectangular insertion portion 420 to enter the rectangular stepped hole 421, and is configured such that an upper end of the guide connection portion 472 is detachably connected with a lower end of the guide plate 440; an inclined surface 473 is arranged below the main body 471, and the inclined surface 473 contacts the elastic expansion board 450.

In this way, when the clamping force of the user's legs to the saddle increases, a force is generated that the inner pipe body unit 400 contracts with respect to the outer pipe body unit 500. In one case, the transmission of the clamping force through the force can completely overcome the elastic force of the spring element 460 so that the elastic teeth 430 can be completely contracted, continuously from one tooth slot 521 to the next tooth slot 521 so that the inner pipe unit 400 can be contracted with respect to the outer pipe unit 500; in another case, as the clamping force of the both legs to the saddle becomes smaller, the clamping force is not completely overcome the elastic force of the spring member 460 through the force conduction, the elastic teeth 430 are not completely contracted, the elastic teeth 430 are held in one of the tooth grooves 521, and the inner pipe body unit 400 is not expanded and contracted with respect to the outer pipe body unit 500.

Through the above arrangement, when the clamping force of the user's legs to the saddle is increased, the body unit 310 is naturally stressed to generate inward deformation, the clamping force can completely overcome the elasticity of the spring element 460 through force conduction, the inner pipe body unit 400 can be contracted relative to the outer pipe body unit 500, and the partial pressure of the saddle to the human body is relieved; as the body unit 310 is deformed, the clamping force of the legs to the saddle naturally becomes small, the clamping force cannot completely overcome the elastic force of the spring element 460 through the force conduction, and the inner tube body unit 400 cannot be contracted with respect to the outer tube body unit 500, so that the body unit 310 automatically stops being deformed and is in the most comfortable form for the human body.

It should be noted that, after the inner pipe unit 400 is assembled, the action coupling block 470 presses the guide plate 440 to move upward in the rectangular stepped hole 421 under the action of the spring member 460, and is limited by the top surface of the large diameter portion, i.e., the spring member 460 always presses the action coupling block 470 and the guide plate 440 together. The inner tubular unit 400 is assembled into the outer tubular unit 500, and the elastic teeth 430 are always kept not to be separated from the guide plate 440 or to be pressed together with the guide plate 440 by the restraining and/or pressing action of the tooth grooves 521.

In other words, the detachable connection between the elastic teeth 430 and the guide plate 440, and the detachable connection between the action coupling blocks 470 and the guide plate 440, ensure that the guide plate 440 is conveniently positioned and matched during assembly, and do not need to consider that the guide plate 440 is separated from the elastic teeth 430 and the action coupling blocks 470. Specifically, the toothed plate 431 and the guide plate 440 are provided with positioning blocks on the lower end surfaces thereof, and the guide plate 440 and the guide connection portion 472 are provided with positioning grooves on the upper end surfaces thereof, which are matched with the positioning blocks. Preferably, a manner of quick connection and disassembly such as a magic tape or a magnet can be configured between the lower end surface of the positioning block and the bottom surface of the positioning groove, so that the connection stability of the guide plate 440, the elastic teeth 430 and the action joint block 470 is improved in the assembly process of the inner pipe body unit 400.

It should be noted that, the spring element 460 of the present embodiment is configured as an active spring, so that a user can adjust the elastic coefficient of the spring element 460 according to his own use experience, so that when the clamping force of the user's legs to the saddle is increased, the critical point of the body unit 310 for automatically stopping deformation is matched with the requirements of different users, and the applicability of the product is improved.

Specifically, the roller 451 is mounted on the upper end surface of the elastic expansion plate 450, and the inclined surface 473 is provided with the roller groove 474 for relative movement between the elastic expansion plate 450 and the action coupling block 470.

The spring element 460 includes a mechanical spring 461 and an adjustable spring 462 connected in series, specifically, the adjustable spring 462 is fixedly installed at the bottom of the configuration cavity 422, one end of the mechanical spring 461 is connected with the adjustable spring 462, and the other end is connected with the lower end surface of the elastic expansion plate 450, so that the elastic state of the whole spring element 460 is changed by adjusting the elastic coefficient of the adjustable spring 462.

It will be appreciated that the adjustable spring 462 is electrically adjustable and that the interior of the inner tubular unit 400 is configured with a battery module (not shown).
