[0042] By providing the side seat 28 and the massage roller 29, the body position of the elderly can be limited. When the volunteer pushes the push handle 26 to drive the entire device and the elderly to move on the road, the volunteer manually rotates the push handle 26 to drive the second threaded rod 39 to rotate. Under the threaded cooperation between the second threaded rod 39 and the inflation tube 38, the piston rod can be driven to move along the inflation tube 38, so that the air in the inflation tube 38 is repeatedly squeezed into the cylinder 37, driving the cylinder 37 to continuously expand and contract.

[0043] See also Figure 1-Figure 8 As another preferred embodiment of the present application, the auxiliary mechanical device also includes a deceleration component for monitoring the moving speed of the moving wheel 2 and adjusting the speed of the moving wheel 2 when the moving speed of the moving wheel 2 reaches an expected value.

The detection module is arranged on the other wheel axle 3 and is electrically connected to the reducer 40, and is used to detect the rotation speed of the moving wheel 2 and control the operation of the reducer 40.

[0045] When the volunteer pushes the push handle 26 to drive the entire device to move, it can drive the wheel axle 3 to rotate, and then drive the turntable 44 to rotate. During the rotation of the turntable 44, due to the action of centrifugal force, the third magnetic block 45 can be driven to move outward relative to the turntable 44, thereby reducing the distance between the third magnetic block 45 and the magnetic slide 43. Under the action of the repulsive force between the two, the magnetic slide 43 can be driven to move relative to the detection cover 41. The moving distance of the magnetic slide 43 can be monitored in real time through the detector 42. When the volunteer loses control on the downhill section, the rotation speed of the wheel axle 3 is accelerated, thereby further reducing the distance between the third magnetic block 45 and the magnetic slide 43. At this time, the detector 42 can control the reducer 40 to reduce the rotation speed of the moving wheel 2, thereby ensuring the safety of the downhill section of the entire device.

[0046] How this application works:

[0047] When the elderly stand on the lifting platform 12, under the action of the elderly's gravity, the lifting platform 12 moves down and the sliding column is inserted into the matching groove on the swing rod. When the volunteer pushes the push handle 26 to drive the entire device to move, the moving wheel 2 and the wheel shaft 3 can be driven to rotate. When the wheel shaft 3 rotates, the first gear 11 can be driven to rotate. Under the meshing action between the first gear 11 and the first rack 21, the moving seat 20 and the first rack 21 can be driven to move in the horizontal direction. When the moving distance of the moving seat 20 reaches the set value, the electric telescopic rod 24 The extension drives the first rack 21 to move up relative to the moving seat 20, so that the first rack 21 and the first gear 11 are disengaged, and then the gear frame 22 is driven to reciprocate. Under the meshing action between the gear frame 22 and the third gear 23, the third gear 23 can be driven to rotate repeatedly, and then the swing rod is driven to swing repeatedly, and the foot seat 13 is driven to move in the horizontal direction, and the movement directions of the two foot seats 13 are opposite. Due to the arrangement of the first magnetic block 14 and the second magnetic block 15, the foot seat 13 can be moved along the path of the guide groove 18, so that it is convenient for the elderly to follow The normal walking action exercises the lower limbs. By setting the side seat 28 and the massage roller 29, the body position of the elderly can be limited. When the volunteer pushes the push handle 26 to drive the entire device and the elderly to move on the road, the volunteer manually rotates the push handle 26 to drive the second threaded rod 39 to rotate. Under the thread cooperation between the second threaded rod 39 and the inflation tube 38, the piston rod can be driven to move along the inflation tube 38, so that the air in the inflation tube 38 is repeatedly squeezed into the cylinder 37, driving the cylinder 37 to continuously expand and contract. During the continuous extension and retraction process, the second rack 35 can be driven to reciprocate. Under the meshing action between the second rack 35 and the second gear 36, the second gear 36 and the clamping shaft 34 are driven to rotate, and then the bidirectional screw 31 is driven to rotate. Under the threaded cooperation between the bidirectional screw 31 and the sleeve, the lifting block and the side seat 28 can be driven to reciprocate along the vertical direction, and then the massage roller 29 has a resistance massage effect on the waist and thigh of the human body, thereby strengthening the blood flow function of the lower body of the elderly, making the lower limb exercise effect of the elderly better.

[0048] When the volunteer pushes the push handle 26 to drive the entire device to move, it can drive the wheel axle 3 to rotate, and then drive the turntable 44 to rotate. During the rotation of the turntable 44, due to the action of centrifugal force, the third magnetic block 45 can be driven to move outward relative to the turntable 44, thereby reducing the distance between the third magnetic block 45 and the magnetic slide 43. Under the action of the repulsive force between the two, the magnetic slide 43 can be driven to move relative to the detection cover 41. The moving distance of the magnetic slide 43 can be monitored in real time through the detector 42. When the volunteer loses control on the downhill section, the rotation speed of the wheel axle 3 is accelerated, thereby further reducing the distance between the third magnetic block 45 and the magnetic slide 43. At this time, the detector 42 can control the reducer 40 to reduce the rotation speed of the moving wheel 2, thereby ensuring the safety of the downhill section of the entire device.
