[0030] In addition, the self-adjusting structure of the massage movement of the massage chair can also include a lifting motor. The body of the lifting motor can be hinged on the bracket 5, and the sides of the connecting block 15 of the two unit massage mechanisms 1 are provided with protrusions, the two protrusions 151 are opposite, and an axis can be connected between the two protrusions 151. The output shaft of the lifting motor is connected to the axis, so that the lifting motor can drive the axis to move, thereby changing the position of the connecting block 15, that is, changing the height of the connecting block 15, thereby changing the height of the massage wheel 11.

[0031] The bracket 5 is provided with a plurality of through holes 51. In the present embodiment, the number of the through holes 51 is equal to the number of the unit massage mechanisms 1, that is, there are preferably two through holes 51. The movable arms 12 of the two unit massage mechanisms 1 pass through the two through holes 51 one by one. The through holes 51 can limit the movable range of the movable arms 12 to prevent the movable arms 12 from moving beyond expectations and causing damage to themselves or other structures.

[0032] The utility model can be used in a massage chair, and by starting the travel motor 41, the travel motor 41 can drive the driving shaft 43 to rotate, thereby driving the driving roller 42 to rotate, and the driving roller 42 can move along the guide rail 22 to change the position of the utility model, so as to facilitate the utility model to massage different parts of the user, and when the utility model moves, the driven roller 44 can rotate accordingly to assist the movement of the utility model.

[0033] Furthermore, the connecting block 15 can be driven to swing by starting the lifting motor, thereby changing the height of the connecting block 15, thereby changing the height of the massage wheel 11, so that the massage wheel 11 can fit the position where the user needs to massage as much as possible, avoiding discomfort or ineffective contact with the user during massage, resulting in no sensation.

[0034] When the tapping massage of the present utility model is required, the tapping motor 21 can be started. The tapping motor 21 can drive the driving wheel 22 to rotate. The rotation of the driving wheel 22 can drive the rotating shaft 23 to rotate. Then, the rotating member 13 on the rotating shaft 23 follows the movement. And since the connection between the connecting member 14 and the movable arm 12 is a ball head, the movement of the rotating member 13 can drive the movable arm 12 to swing to a certain extent through the connecting member 14. Thus, by operating and changing the forward and reverse rotation of the output shaft of the tapping motor 21, the movable arm 12 can be effectively swung back and forth within a certain range, so that the massage wheel 11 connected to the movable arm 12 can perform tapping massage on the user.

[0035] When the kneading massage of the present utility model is required, the kneading motor 31 can be started. The kneading motor 31 can drive the worm 33 to rotate. The rotation of the worm 33 causes the worm wheel to rotate accordingly. And the lead screw 34 can rotate along with the rotation of the worm wheel. The nut 35 can move linearly along the lead screw 34 accordingly, and the two nuts 35 can move in opposite directions. And the movable arm 12 can move along with the movement of the nut 35. Thus, by operating and changing the forward and reverse operation of the kneading motor 34, the two movable arms 12 can move away from each other and then approach each other from time to time, so that the massage wheel 11 connected to the movable arm 12 can perform kneading massage on the user.

[0036] For the convenience of automatic control, the tapping motor 2, the kneading motor 3, the walking motor 4, the lifting motor, etc. on the self-adjusting structure of the massage chair massage mechanism can all be controlled by an external control device and driven by a MOS tube.

[0037] Preferably, the control device can count the operation of the tapping motor 21 to facilitate recording the number of taps, etc., and can report a fault correspondingly if no counting pulse is detected when starting the tapping motor 21.

[0038] Preferably, the control device can correspondingly control the operation of the kneading motor 31 by presetting the working parameters of the kneading motor 31 so that the two movable arms 12 are in a specific position to obtain a specific distance, and can be correspondingly counted as positions such as wide, medium, and narrow. And a sensor can be correspondingly set to be connected to the control device. When the sensor does not sense that the movable arm 12 is not in a specific position at a specific time, an error will be reported correspondingly.

[0039] Preferably, a position detection device can be set to be connected to the control device to feedback the real-time position of the self-adjusting structure of the massage chair massage mechanism so that the control device can control the operation of the walking motor 41, enabling the self-adjusting structure of the massage chair massage mechanism to stop at a specific position. And a limit switch can be correspondingly set, which can be connected to the control device so that when the self-adjusting structure of the massage chair massage mechanism moves to the position where the limit switch is located, the control device can timely stop the continuous operation of the walking motor 41.

[0040] Therefore, the utility model can effectively realize massage actions such as knocking and kneading, as well as the adjustment of walking positions. It has a variety of action types and is suitable for automatic control, which can conveniently meet the needs of different users for massage positions and different massage action requirements. It has high comfort, strong flexibility in use, and high market competitiveness.

[0041] The above are only some embodiments of the utility model. For those of ordinary skill in the art, without departing from the creative concept of the utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model.
