The rotation of the transmission shaft 7 can drive the annular groove 10a to rotate synchronously, and the movement track of the annular groove 10a is in the shape of a wave swinging back and forth in the vertical plane, due to the resistance of the shoulder support surface sleeve or the shoulder of the passenger, the massage swing arm 11 is forced to move reciprocally along the axial direction of the transmission shaft 7 under the driving action of the oblique side walls of the annular groove 10a, so as to make the massage head 3 at the distal end swing reciprocally, thereby simulating the kneading massage on the shoulder of the passenger and relieving the fatigue of the passenger's shoulder.

[0043] Further, the driving assembly B further includes a motor 4 fixedly installed at the middle position inside the shoulder support framework 2, the output end of the motor 4 is connected with a worm 5 extending in the vertical direction, the worm 5 is meshingly connected with a worm wheel 6, and the worm wheel 6 is fixedly sleeved on the transmission shaft 7, so as to convert the power transmission from the longitudinal direction to the horizontal direction, thereby greatly reducing the overall thickness of the shoulder support 1.

[0044] In this embodiment, the positioning wheel 8 is also fixedly installed in the shoulder support frame 2 by the positioning sleeve 9. The positioning wheel 8 is provided with two, which are symmetrically distributed on the left and right sides of the worm wheel 6. The transmission shaft 7 is rotatably supported in the positioning wheel 8. In this way, the stable meshing transmission of the worm wheel 6 and the worm 5 can be ensured.

[0045] Further, as shown in Figure 5 and Figure 6 , the eccentric wheel 10 is fixedly installed at both ends of the transmission shaft 7, and the annular groove 10a is formed on the eccentric wheel 10. The massage swing arm 11 includes the annular part 11a rotatably installed in the annular groove 10a, and the rod-shaped part 11b provided on the upper end of the annular part 11a. The extension direction of the rod-shaped part 11b is consistent with the inclination direction of the annular groove 10a. The massage head 3 is fixedly installed at the top front end position of the rod-shaped part 11b. In this way, the massage head 3 can be ensured to be in the backward folding state in the non-use state of the massage assembly A.

[0046] As shown in Figure 3 , the retracting control mechanism C is also installed in the shoulder support 1. The retracting control mechanism C is used to switch the massage head 3 between protruding from the surface of the shoulder support 1 and folding in the inside of the shoulder support 1.

[0047] Specifically, as shown in Figures 7 to 11As shown, the contraction control mechanism C comprises a slider 13 and a driving member 12 for reciprocating the slider 13 inside the shoulder support framework 2. In this embodiment, the driving member 12 can be a cylinder or a lead screw motor. A recess 13a is formed on the top of the slider 13. A guide rod 11c is formed on the end of the annular part 11a away from the massage head 3, and is located in the recess 13a. The recess 13a has a guide slope 13b on one side. In this embodiment, the slider 13 is in a long strip shape and is arranged parallel to the transmission shaft 7. The recess 13a is arranged on the end close to the annular recess 10a, and the guide slope 13b extends towards the outside rear end of the shoulder support framework 2. A mounting block 13c extending downward is formed on the slider 13, and the output end of the driving member 12 is fixedly connected to the mounting block 13c. When the driving member 12 drives the slider 13 to move towards the middle position of the shoulder support framework 2, the transmission action of the guide slope 13b and the guide rod 11c can make the massage swing arm 11 swing forward, thereby realizing the forward unfolding of the massage assembly A. The hanging part 11d extends outward on the side of the rod-shaped part 11b, and the first elastic element 14 is connected to the rear end of the shoulder support framework 2. In this embodiment, the first elastic element 14 is a tension spring, which can continuously exert a rearward pulling force on the massage swing arm 11. In this way, the shoulder kneading massage device can be stably folded during non-use, thereby avoiding the feeling of foreign matter to the passenger and affecting the riding comfort. When the shoulder kneading massage device is used, the guide rod 11c can rely on the pulling force of the first elastic element 14 to abut against the recess 13a again, thereby completing the folding of the massage assembly A.

[0048] In combination with the above structure, the specific working principle of the shoulder kneading massage device is as follows:

[0049] When the shoulder kneading massage device is not in use, the massage arm 11 is in a retracted state due to the pulling force of the first elastic element 14, and the guide rod 11c is located in the groove 13a. When the shoulder kneading massage device needs to be used, the drive component 12 drives the slider 13 to slide towards the middle position of the shoulder support frame 2. At this time, under the transmission action of the guide inclined surface 13b and the guide rod 11c, the massage arm 11 can rotate forward as a whole, and the massage head 3 can be pressed against the shoulder support cover. Then, the motor 4 runs, and the power is transmitted through the worm gear 6 and worm 5, causing the transmission shaft 7 to rotate. The massage head 3 is blocked by the seat cover and the occupant's shoulder, and cannot rotate forward synchronously. Under the transmission action of the inclined side wall of the annular groove 10a, the massage head can be driven to swing back and forth along the axis of the transmission shaft 7, thereby simulating a kneading massage on the occupant's shoulder and effectively relieving shoulder fatigue. When the shoulder kneading massage device is finished, the drive component 12 drives the slider 13 to slide toward the side of the shoulder support frame 2. Under the pulling force applied by the first elastic element 14, the upper end of the massage arm 11 rotates backward, thereby causing the massage head 3 to fold. The guide rod 11c is affected by the rotational force of the massage arm 11 and rests against the groove 13a again.

[0050] Example 2:

[0051] like Figure 15 As shown, a car seat includes a seat back 15, and a shoulder kneading massage device as described in Embodiment 1 is integrated and installed at the shoulder position of the seat back 15.

[0052] like Figures 12 to 14 As shown, the shoulder support 1 is mounted on the shoulder position of the seat back 15 in a flip-forward configuration. A second elastic element 20 is installed between the shoulder support 1 and the seat back 15. The second elastic element 20 applies a thrust that causes the shoulder support 1 to flip forward relative to the seat back 15. A drive mechanism is also installed between the shoulder support 1 and the seat back 15. The drive mechanism is used to actively control the shoulder support 1 to rotate and fold backward against the resistance of the second elastic element 20. When the shoulder support 1 is in the forward-extended state, the thrust from the occupant's shoulder can force the shoulder support 1 to passively rotate and fold backward against the resistance of the second elastic element 20.

[0053] Specifically, the drive mechanism includes a drive motor 16 fixedly installed at the rear end of the seat back 15, a lead screw 17 installed at the output end of the drive motor 16, the lead screw 17 being arranged along the length of the seat back 15, a moving block 18 being threaded onto the lead screw 17, the lower ends of the shoulder support 1 being rotatably installed on the seat back 15, and a rearwardly extending swing arm 19 being fixedly installed on the shoulder support 1, the swing arm 19 being formed with a locking groove 19a, the locking groove 19a being open upward, and the lower end of the moving block 18 abutting against the locking groove 19a, the second elastic element 20 being a pneumatic spring, the two ends of which are respectively rotatably installed on the middle of the swing arm 19 and the base of the drive motor 16.

[0054] In combination Figure 12 And Figure 13 , the automobile seat is in the state of non-use, the moving block 18 is at the lowermost end of the screw rod 17, and the second elastic element 20 is in the force storage state through the swing arm 19, when the driving motor 16 drives the moving block 18 to move upwards along the screw rod 17, the second elastic element 20 can be unloaded upwards, thereby pushing the swing arm 19 to move upwards, so that the shoulder support 1 rotates forward to meet the needs of passengers of different body types for the shoulder support 1, and the locking groove 19a is always below the end of the moving block 18 throughout the process. In combination Figure 14 , when the shoulder support 1 is in the forward unfolded state, the swing arm 19 is forced to move downwards by overcoming the upward thrust of the second elastic element 20 under the thrust from the shoulder of the passenger, the locking groove 19a moves downwards and separates from the moving block 18, thereby making the shoulder support 1 passively fold backwards, so that when the automobile is subjected to a collision, the shoulder support 1 can collapse backwards to slow down the impact force on the shoulder of the passenger, and the pneumatic spring 20 further slows down the impact force on the passenger, thereby ensuring the safety of the passenger. Throughout the collapsing process, no force is applied to the moving block 18, thereby ensuring that the screw rod 17 is not damaged and the service life of the entire driving mechanism is ensured.

[0055] Finally, it should be noted that the above description is only the preferred embodiment of the present application, and those skilled in the art can make various similar representations under the inspiration of the present application without departing from the purpose and claims of the present application, and such changes fall within the protection scope of the present application.
