In one embodiment of the invention, the drive assembly includes a motor 121; two ends of the motor 121 respectively extend out of a worm 122; the worm 122 is meshed with the driving teeth 123; the transmission teeth 123 are double-layer gears, one layer is a worm wheel and is used for being meshed with the worm 122, and the other layer is a straight gear and is used for being meshed with the driving teeth 124 to drive the driving teeth 124 to rotate; the driving teeth 124 are provided with an output shaft 125; the output shaft 125 passes through the through hole 112 provided on the upper shell 110 and is connected with the deflection wheel 210 in a rotation-stopping way; the upper end of the output shaft 125 is a flat head 126; the deflection wheel 210 is provided with a connecting hole 211 matched with the flat head 126; the deflection wheel 210 is connected with the flat head 126 through a connecting hole 211 to realize the rotation stopping connection between the output shaft 125 and the deflection wheel 210;

It should be noted that, the connection between the output shaft 125 and the deflection wheel 210 is to realize eccentric rotation of the deflection wheel 210; thus, in an embodiment, the output shaft 125 may be disposed at the center of the driving gear 124, and the deflection wheel 210 is an eccentric wheel, and the eccentric rotation of the deflection wheel 210 may be achieved by the connection of the output shaft 125 and the deflection wheel 210, where the center of the eccentric rotation is the center of the deflection wheel 210; in another embodiment, the output shaft 125 may be disposed at the eccentric position of the driving tooth 124, and the connection hole 211 on the deflection wheel 210 may be located at the center or eccentric position of the deflection wheel 210, so that the eccentric rotation of the deflection wheel 210 may be achieved, where the center of the eccentric rotation is the center of the driving tooth 124, and the through hole 263 may be disposed larger or in a ring shape due to the eccentric arrangement of the output shaft 125, so as to satisfy the movement of the output shaft 125; when the output shaft 125 is eccentrically disposed, and the coupling hole 211 of the deflection wheel 210 is also eccentrically disposed, the rotation track of the deflection wheel 210 is relatively complex, and the effects of the present invention can be achieved as well.

In an embodiment of the present invention, a limit rib 212 of a limit swing seat 220 is disposed on the top of the deflection wheel 210; the swing seat 220 can be limited below the limit flange 212 through the limit flange 212, so that the swing seat 220 is prevented from being separated from the eccentric wheel; in another embodiment, the effect of limiting the swinging seat 220 can be achieved by using the edge of the massage head 230 by fixedly connecting the massage head 230 to the eccentric wheel, so that the structure of the limiting flange 212 can be omitted; in another embodiment, the massage head 230 is fixedly connected to the swing base 220; the massage heads 230 are driven by the deflection wheels 210 or the swinging seat 220 to do eccentric reciprocating motion, the motion track is similar to ellipse, when two massage heads 230 are arranged, the massage heads 230 can be mutually close to or far away from each other, thereby realizing the effect of massage kneading; in another embodiment, the massage head 230 may be provided with a split structure, including a fixing seat 231 and a rubber sleeve 232 sleeved outside the fixing seat 231; the fixed seat 231 is fixedly connected with the swing seat 220 or the deflection wheel 210; the rubber sleeve 232 can improve the comfort level during massage;

It should be noted that, the massaging head 230 of the present invention is also an optional structure, the non-uniform massaging of the present invention is mainly implemented by the massaging portion 261 of the massaging arm 260, the massaging portion 261 can also act on the human body to perform massaging when working alone, but the massaging area and the working mode are relatively single; for a larger massage area and a kneading effect, a combined structure of the massage head 230 and the massage arm 260 is preferably adopted, and two massage heads 230 and two massage arms 260 are respectively arranged; that is, the driving component drives the two massage components to work; the massage assembly includes a massage head 230 and a massage arm 260; the massage head 230 moves at a uniform speed in its own motion path, and the massage part 261 of the massage arm 260 moves at a non-uniform speed in its own motion path;

In an embodiment of the present invention, the housing 100 includes an upper case 110 and a lower case 120; the driving assembly is arranged in the accommodating middle formed by the upper shell 110 and the lower shell 120;

In an embodiment of the present invention, the chute assembly includes a chute 221 provided on the swing seat 220 and a limit post 111 fixedly provided on the housing 100 and engaged with the chute 221; the sliding groove 221 may be a long straight groove or an arc groove; the limit post 111 may be integrally formed with the upper case 110 or may be fixedly disposed on the upper case 110 by a screw; the limit posts 111 are inserted into the slide grooves 221, and the width of the slide grooves 221 is generally equal to the size of the limit posts 111, so that the movement track of the swing seat 220 is ensured to be relatively fixed; in another embodiment, a limit retainer ring 224 located on the upper end surface of the chute 221 is fixedly connected to the top of the limit post 111; the sliding groove 221 can be prevented from being separated from the limiting column 111 by the limiting retainer ring 224; in another embodiment, the chute 221 of the chute assembly may be disposed on the upper shell 110, and the limit post 111 is disposed on the swing seat 220, so as to limit the movement track of the swing seat 220;

as shown in fig. 1-2, in one embodiment of the present invention, the swing seat 220 includes a collar 223 that is sleeved on the deflection wheel 210; the swing seat 220 is movably connected with the swing pull rod 240 through a connecting column 222; the connecting column 222 is positioned below the swing seat 220; the upper shell 110 is also provided with a yielding groove 113; the swing pull rod 240 is arranged in the abdication groove 113 and connected with the connecting column 222; the flat setting position of the swing pull rod 240 is ensured through the abdication groove 113, and the connecting column 222 is accommodated; in another embodiment, the connection post 222 may be disposed above the swing seat 220;

In an embodiment of the present invention, the swing link 240 is movably connected to the middle of the massage arm 260 through a connection block 250; one end of the connecting block 250 is hinged with the swing pull rod 240, and the other end is connected with a connecting groove 262 arranged in the middle of the massage arm 260 through a bolt 251; by adding the connection block 250 to connect with the massage arm 260, the swing of the massage arm 260 can be stabilized; as shown in fig. 3-4, the end of the massage arm 260 away from the massage part 261 is rotatably connected with the housing 100, and through the indirect connection of the connection block 250, the rotation of the swing pull rod 240 during operation only acts on the connection post 222 and the connection block 250, but is not directly transmitted to the massage arm 260, and the massage arm 260 can swing up and down reciprocally in fig. 3-4;

As shown in fig. 1, in an embodiment, the connecting groove 262 is a long waist groove, and one end of the massage arm 260 away from the massage portion 261 is rotatably connected with the housing 100, so that when the swing pull rod 240 pulls the massage arm 260 to swing rotationally, the connection position between the swing pull rod 240 and the massage arm 260 has a change in height, and when the connecting groove 262 is a long waist groove, the change in height can be counteracted, so that the swing pull rod 240 always moves in a plane where the bottom surface of the abdication groove 113 is located;

If the swing pull rod 240 is directly hinged with the massage arm 260, the swing pull rod 240 is driven to move in a direction away from the bottom surface of the abdication groove 113 by a certain up-down fluctuation when in operation, when the swing pull rod 240 is connected with the swing seat 220 through the connecting column 222, the swing pull rod 240 is also interfered with the connecting column 222 under the driving of the massage arm 260, so that the operation is unstable, the long-time use of the swing pull rod 240 is not facilitated, the massage arm 260 can be prevented from driving the swing pull rod 240 to move by setting the connecting groove 262 as a long waist groove, and the operation stability of the swing pull rod 240 is ensured;

In another embodiment, the swing link 240 and the swing seat 220 may be connected by using a universal ball, so that the connection part has more degrees of freedom, the other end of the swing link 240 is hinged to the middle part of the massage arm 260, and the swing link 240 does not influence the smooth operation of the swing link 240 due to the fluctuation formed by the swing ball when the swing seat 220 and the swing link 240 swing the massage arm 260, but the structure of the embodiment is more complex, the difficulty in installation and manufacturing is higher, each connection structure of the massage machine core is usually a plastic piece, and if the universal ball is replaced by a plastic piece, the precision and the service life are reduced; if a metal piece is used, the cost is quite higher;

In an embodiment of the present invention, a through hole 263 is disposed at an end of the massage arm 260 away from the massage portion 261; a rotating shaft 264 rotatably connected with the casing 100 is arranged in the through hole 263; the rotating shaft 264 is matched with the clamping groove 127 arranged on the lower shell 120; thereby effecting rotation of the massage arm 260; the massage arm 260 rotates around the rotation shaft 264, and makes non-uniform reciprocating swing motion under the pulling of the swing pull rod 240; in another embodiment, the massage arm 260 may be connected to the housing 100 by a universal ball, and the massage range of the massage arm 260 is correspondingly increased under the action of the swing lever 240;

Working principle: see fig. 3-5; in fig. 3, the left swing seat 220 is illustrated, and the leftmost end of the sliding slot 221 is matched with the limit post 111, and the connecting post 222 is located at the rightmost end of the first movement track a; in fig. 4, the rightmost end of the sliding slot 221 is matched with the limiting post 111, and the connecting post 222 is located at the leftmost end of the first movement track a; the inclined elliptical-like line in fig. 3-4 is the first motion profile a of the link 222, similar to the inclined elliptical profile; the connecting column 222 moves along the first movement track a and drives the swing pull rod 240 to move, so as to pull the massage arm 260 to rotate around the rotating shaft 264, in particular to reciprocate along the Y-axis direction in fig. 3-4; the swing link 240, when in motion, approaches or moves away from the output shaft 125;

Referring to fig. 5, a specific analysis is performed by dividing the first motion track a of the connecting column 222 into a first section A1, a second section A2, and a third section A3, where the motion direction of the connecting column 222 is counterclockwise, that is, the first section A1 returns to the first section A1 for circulation after passing through the second section A2 and the third section A3 in sequence; the movement speed of the connecting column 222 in the first section A1, the second section A2 and the third section A3 is the same, and the connecting column moves at a uniform speed; the connecting column 222 has the slowest movement speed of the massage part 261 when the first section A1 moves, has the slightly faster movement speed of the massage part 261 when the second section A2 moves, and has the fastest movement speed of the massage part 261 when the third section A3 moves; thereby forming non-uniform reciprocating motion of the massage part 261;

in fig. 3 to 4, the directions in which the arrows of the X axis and the Y axis point are defined as the X axis forward direction and the Y axis forward direction, the directions opposite to the X axis forward direction are the X axis reverse direction, and the directions opposite to the Y axis forward direction are the Y axis reverse direction;

When the connecting column 222 moves along the first section A1, analysis is started from the leftmost side of the first section A1, at this time, the position of the swing rod 240 in fig. 3 should be a vertical position (parallel to the Y axis), and the position of the swing rod 240 is on a straight line with the massage arm 260, that is, the position of the swing rod 240 represented by a dashed line in fig. 5, the connecting column 222 further moves to the position of fig. 3, during the process, the connecting column 222 has a small first displacement S1 in the reverse direction along the Y axis during the track movement of the first section A1, the swing rod 240 rotates clockwise by a certain angle, when the swing rod 240 rotates clockwise, it is assumed that the swing rod 240 rotates around the other end fixed point, the joint of the swing rod 240 and the connecting column 222 also generates a small second displacement S2 in the reverse direction along the Y axis, and the directions of the two displacements are the same, that is, after the first displacement S1 needs to subtract the actual displacement in the reverse direction along the Y axis generated when the swing rod 240 rotates, the swing rod 240 acts on the massage arm 260, the actual distance of the massage arm 260 is driven; since the rotation of the swing link 240 is not fixed during the actual movement, the actual displacement along the Y-axis direction generated when the swing link 240 rotates is not well calculated;

for convenience of analysis, it is assumed that the second displacement S2 is a displacement along the Y-axis that occurs after the swing link 240 rotates by a certain angle during the track movement of the first segment A1;

when the first displacement S1 is equal to the second displacement S2, the difference between the two is zero, that is, the distance along the reverse direction of the Y axis during the movement of the connecting column 222 is offset by the distance along the reverse direction of the Y axis during the clockwise rotation of the swing link 240, the swing link 240 does not directly push the massage arm 260 to generate displacement along the Y axis, the movement distance of the massage arm 260 is zero, the movement speed of the massage portion 261 is zero, and the massage portion 261 is relatively stationary;

When the first displacement S1 is greater than the second displacement S2, since the swing link 240 is connected to the connection post 222, the swing link 240 moves along with the connection post 222, in this case, the distance along the Y-axis reverse movement cannot be offset by the first displacement S1 when the swing link 240 rotates by a certain angle, so that the connection post 222 moves to push the massage arm 260 reversely along the Y-axis by the swing link 240 by a certain distance, but the distance along the Y-axis reverse movement of the massage arm 260 is offset by a part of the rotation of the swing link 240, so that the speed of the massage arm 260 during the movement of this section is still slower;

When the first displacement S1 is smaller than the second displacement S2, since the swing link 240 is connected to the connection post 222, the swing link 240 moves along with the connection post 222, and the movement of the connection post 222 pulls the massage arm 260 forward to the Y-axis by a certain distance through the swing link 240; in this case, for convenience of understanding, it may be assumed that the first displacement S1 is zero, that is, the motion track of the connection post 222 moves forward along the X axis, when the connection post 222 moves, the swing pull rod 240 is necessarily driven to rotate clockwise, and since the swing pull rod 240 moves along the connection post 222, the connection point of the swing pull rod 240 and the connection post 222 moves forward along the X axis, the second displacement S2 generated after the rotation of the swing pull rod 240 is transferred to the massage arm 260, so that the massage arm 260 drives to pull forward along the Y axis for a certain distance;

Similarly, when the connecting column 222 moves in the second section A2, the connecting column 222 has a displacement along the positive Y axis, and the swing link 240 rotates counterclockwise, the swing link 240 rotates from the position of fig. 3 to the position of fig. 4, and the displacement of the swing link 240 in the Y axis direction due to rotation has a positive direction and a negative direction, so that after the displacement of the connecting column 222 along the positive Y axis is superimposed, the movement distance in the Y axis direction acting on the massage arm 260 also changes constantly, thereby realizing non-uniform movement of the massage arm 260;

Further, when the connecting column 222 moves in the third section A3, the connecting column 222 starts to move from the position shown in fig. 4, and finally the position of the swing link 240 becomes parallel to the Y axis, in this process, the connecting column 222 has a larger displacement along the reverse direction of the Y axis, and the displacement generated by clockwise rotation of the swing link 240 from the position shown in fig. 4 is superimposed with the displacement of the connecting column 222 along the reverse direction of the Y axis, so that the moving distance of the massage arm 260 is rapidly increased, the moving speed of the massage arm 260 is increased, and after the connecting column 222 moves further into the track of the first section A1, the moving speed of the massage arm 260 is rapidly reduced, thereby forming an obvious speed change;

meanwhile, as the swing pull rod 240 is movably connected with the middle part of the massage arm 260, one end of the massage arm 260 away from the massage part 261 is movably connected with the shell 100, when the swing pull rod 240 pulls the massage arm 260 to swing reciprocally, the massage arm 260 actually makes reciprocal circular motion, the massage part 261 serves as the far end of the massage arm 260, the massage part 261 has larger linear velocity, namely, the displacement variation in the Y-axis direction generated by the rotation of the swing pull rod 240 can be amplified by the massage part 261 finally, larger linear velocity is generated, and when the massage part acts on human body massage, the non-uniform motion of the massage part 261 can be more easily felt, and the massage area of the massage part 261 can be correspondingly increased;

It should be noted that the above-described movement process and the change of the movement speed have universality; when the swing link 240 approaches or departs from the output shaft 125 under the limit of the chute assembly, the motion path of the connecting post 222 is similar to the inclined ellipse structure shown in fig. 5, and the swing link 240 is driven to rotate in such motion path, and the rotation of the swing link 240 and the motion of the connecting post 222 produce the non-uniform motion effect of the massage arm 260;

When the motion track of the connecting post 222 reciprocates along the Y-axis direction, the swing pull rod 240 also reciprocates along the Y-axis direction, and the swing pull rod 240 does not rotate with the massage arm 260 during the motion process, so that the massage arm 260 and the connecting post 222 form synchronous motion, and the motion speed of the massage arm 260 becomes uniform, which is not in the protection scope of the present invention; therefore, the invention specifically defines that one end of the swing pull rod 240 far away from the swing seat 220 is movably connected with the middle part of the massage arm 260 and can relatively rotate during operation, when the swing pull rod 240 and the massage arm 260 relatively rotate, the displacement in the Y-axis direction caused by the rotation of the swing pull rod 240 can influence the displacement in the actual Y-axis direction of the massage arm 260, so that the massage part 261 can continuously perform non-uniform reciprocating motion under the uniform driving of the motor 121, and the intermittent motion of manual massage is truly simulated, thereby achieving better massage effect.

When the output shaft 125 is eccentrically disposed, the connection hole 211 on the deflection wheel 210 is also eccentrically disposed, the rotating track of the deflection wheel 210 is relatively complex, which also causes the motion track of the connection post 222 to be more complex, but since the swing pull rod 240 moves close to or far from the output shaft 125 under the limit of the chute assembly, the motion track of the second section A2 and the third section A3 is necessarily present in the motion track, and meanwhile, the swing pull rod 240 and the massage arm 260 relatively rotate, so that the massage portion 261 can be ensured to perform continuous non-uniform reciprocating motion under the uniform speed driving of the motor 121.

Referring to fig. 6 to 7, when the connection post 222 is located at the rightmost end, the distance between the massage heads 230 is the shortest, so that the massage can be effectively performed, and meanwhile, the distance between the massage part 261 and the massage heads 230 is larger;

When the connecting column 222 is positioned at the leftmost end, the distance between the massage heads 230 is the largest, so that the muscles can be relaxed after kneading, and meanwhile, the distance between the massage part 261 and the massage heads 230 is smaller;

When the massage head 230 performs a kneading action during the reciprocating massage, the massage part 261 relaxes the muscles in the vertical direction; when the massage head 230 relaxes the muscles, the massage part 261 performs a kneading action in the vertical direction; that is, the kneading and relaxing of the massage head 230 and the massage part 261 are alternately performed, and the kneading-relaxing action of the massage part 261 is performed at a non-uniform speed, so that the massage head has better use experience when being used for shoulder and neck massage, does not exert force and release force simultaneously, and realizes the persistence of the kneading action by alternately kneading and relaxing two parts.

The massage head 230 also has small-amplitude rotation in the motion process, the shape of the massage head 230 is designed into a hand shape, and the massage head 230 has better massage experience along with the small-amplitude rotation and kneading effect.

The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent changes made by the specification and drawings of the present invention, or direct or indirect application in the relevant art, are included in the scope of the present invention.
