The output end of the reduction motor 301 is installed with a driving gear 311. The chassis 302 is provided with a plurality of chassis fixing holes 322. The reduction motor 301 is installed on the chassis 302. The chassis 302 is provided with a gear hole 321 for setting the driving gear 311. The center of the chassis 302 is provided with a bearing hole 323. The bearing seat 303 is installed inside the bearing hole 323. The bearing seat 303 is rotatably connected to the chassis transmission gear 304 that meshes with the driving gear 311. The upper surface of the chassis transmission gear 304 is fixedly connected with an eccentric shaft 341. The eccentric shaft 341 is rotatably connected to The motion gear 306 has a guide internal gear 305 on its periphery which is concentric with the chassis transmission gear 304. The guide internal gear 305 is meshed with the motion gear 306. A number of gear fixing holes 351 are evenly arranged on the edge of the guide internal gear 305. The gear fixing holes 351 are fixedly connected to the chassis fixing holes 322 on the chassis 302 through bolts and straight threaded sleeves. The upper rotation connection of the motion gear 306 is provided with a crank 361. The top of the guide internal gear 305 is fixedly connected to the slide rail bottom cover 104. The slide rail bottom cover 104 is arranged in a disc shape. The gear fixing hole 351 is connected to the slide rail bottom cover fixing hole 142 by bolts. One end of the crank 361 is fixedly connected with a transmission eccentric shaft 362. The transmission eccentric shaft 362 passes through the output slot 141 and is rotationally connected to the input hole 131.

[0039] Example 1: (Small Scale) During specific implementation, when the gear drive mechanism 3 is driving, the reduction motor 301 works, the reduction motor 301 drives the driving gear 311 to rotate, the driving gear 311 engages the chassis transmission gear 304, and the chassis transmission gear 304 rotates. The chassis transmission gear 304 drives the moving gear 306 on the eccentric shaft 341 to rotate, and the moving gear 306 engages with the guide internal gear 305. The moving gear 306 drives the crank 361 and the transmission eccentric shaft 362 to rotate, so that the transmission eccentric shaft 362 moves linearly inside the output slot 141, and drives the linear motion push rod 103 to move linearly between the two slider guide rails 101 through the transmission eccentric shaft 362.

[0040] At this time, the movement stroke of the linear motion push rod 103 is smaller than the diameter of the guide internal gear 305 .

[0041] For further reference, Figures 7 to 10 The lower surface of the slide rail bottom cover 104 is fixedly connected to a guide plate 308 located directly above the guide internal gear 305. A cross guide groove 381 is provided in the middle of the guide plate 308. The crank 361 is arranged in a long strip shape. The middle part of the crank 361 is rotatably connected to the moving gear 306. The other end of the crank 361 is rotatably connected to an eccentric pulley 363. The eccentric pulley 363 and the transmission eccentric shaft 362 are movably connected to the cross guide groove 381.

[0042] Example 2: (Large range) During specific implementation, when the gear drive mechanism 3 is driving, the reduction motor 301 works, the reduction motor 301 drives the driving gear 311 to rotate, the driving gear 311 engages the chassis transmission gear 304, and the chassis transmission gear 304 rotates, and the chassis transmission gear 304 drives the moving gear 306 on the eccentric shaft 341 to rotate, and the moving gear 306 engages with the guide internal gear 305. The moving gear 306 drives the crank 361 and the eccentric pulley 363 to drive the eccentric shaft 362 to rotate, so that the eccentric pulley 363 and the transmission eccentric shaft 362 move inside the cross guide groove 381, and the transmission eccentric shaft 362 moves linearly inside the output groove 141, and the linear motion push rod 103 is driven by the transmission eccentric shaft 362 to move linearly between the two slider guide rails 101.

[0043] At this time, the movement stroke of the linear motion push rod 103 is equal to the diameter of the chassis transmission gear 304 + the diameter of the motion gear 306 + the length of the crank 361.

[0044] At this time, the movement stroke of the linear motion push rod 103 is greater than the diameter of the guide internal gear 305 .

[0045] Furthermore, the diameter of the driving gear 311 is smaller than the diameter of the chassis transmission gear 304 , the diameter of the chassis transmission gear 304 is smaller than the diameter of the guide inner gear 305 , the diameter of the moving gear 306 is smaller than the diameter of the chassis transmission gear 304 , and the diameter of the moving gear 306 is larger than the diameter of the driving gear 311 .

[0046] In a specific implementation, the diameter of the driving gear 311 is smaller than the diameter of the chassis transmission gear 304, forming a labor-saving driving mechanism, so that the reduction motor 301 can be driven with a smaller power. The diameter of the chassis transmission gear 304 is smaller than the diameter of the guide inner gear 305, so that the chassis transmission gear 304 can rotate inside the guide inner gear 305. The diameter of the moving gear 306 is smaller than the diameter of the chassis transmission gear 304, so that the moving gear 306 can just engage the guide inner gear 305 when rotating following the eccentric shaft 341 of the chassis transmission gear 304.

[0047] Preferably, reference Figures 11 to 13 The sprocket drive mechanism 4 includes: a worm motor 401, a fixed chassis 402, a worm gear 403, a sprocket 404, a chain 405 and a chain extension connecting rod 406. The worm motor 401 is fixed to the edge of the fixed chassis 402. A worm 411 is installed at the output end of the worm motor 401. A worm gear 403 that meshes with the worm 411 is rotatably connected to the fixed chassis 402. A sprocket 404 is coaxially fixedly connected to the worm gear 403. The fixed chassis The other end of 402 is rotatably connected to a sprocket 404, a chain 405 is provided between the two sprockets 404, a chain extension link 406 is rotatably connected to the chain 405, and the other end of the chain extension link 406 is rotatably connected to a link output shaft 461. The slide rail bottom cover 104 is arranged in a long strip shape, and the slide rail bottom cover 104 is fixedly connected to the fixed chassis 402 by bolts and straight threaded sleeves. The output shaft 461 passes through the output slot 141 and is rotatably connected to the input hole 131.

[0048] Embodiment 3: (The worm motor 401 drives the worm 411 to drive the chain 405) During specific implementation, the worm motor 401 drives the worm 411 to rotate, so that the worm 411 drives the worm gear 403 to rotate, so that the worm gear 403 drives the sprocket 404 to rotate, and then drives another sprocket 404 to rotate through the chain 405, so that the chain extension link 406 on the chain 405 moves with the chain 405, so that the connecting rod output shaft 461 moves with the chain extension link 406, so that the connecting rod output shaft 461 drives the linear motion push rod 103 to move linearly between the two slider guide rails 101 through the input hole 131.

[0049] Since the driving worm gear 403 cannot drive the worm 411 to rotate, when the linear motion push rod 103 is extended, an effective support structure can be formed. At this time, the sprocket drive mechanism 4 can only be driven by the worm motor 401.

[0050] Furthermore, the diameter of the worm gear 403 is greater than the diameter of the sprocket 404 .

[0051] During specific implementation, the gear drive mechanism 3 and the sprocket drive mechanism 4 can be selectively assembled and combined in different ways according to different requirements.

[0055] Both sides of the lower calf frame 9 are slidably connected to both sides of the upper calf frame 8 through sliding grooves.

[0056] When the gear located between the front end center of the massage chair base frame 5 and the front end center of the massage chair seat frame 6 repeatedly links the push rod to work, the linear motion push rod 103 is extended and retracted, so that the front end of the massage chair seat frame 6 rises upward, and the massage chair seat frame 6 as a whole rotates around the rotating shaft 601, thereby realizing the rocking function.

[0057] Example 2: A massage chair (massage chair seat 6 can be shaken up and down) Preferably, reference Figures 14 and 15 , both sides of the middle part of the massage chair base frame 5 are fixedly connected with a gantry 502, and the inner side of the gantry 502 is rotatably connected with two gantry rollers 503, and both sides of the massage chair seat frame 6 are fixedly connected with a roller slide groove 603, and the roller slide groove 603 is arranged in an arc shape.

[0058] During specific implementation, when the gear linearly and repeatedly linked push rod located between the lower calf frame 9 and the upper calf frame 8 is working, the linear motion push rod 103 extends and contracts, causing the lower calf frame 9 to slide up and down on the upper calf frame 8, causing the lower calf frame 9 to extend upward and contract upward.

[0059] Both sides of the lower calf frame 9 are slidably connected to both sides of the upper calf frame 8 through sliding grooves.
