AI Technical Summary
Existing mirror reciprocating motion devices require a large clearance to achieve smooth movement when reciprocating in one direction in the vertical direction, but this results in high noise and severe structural wear, affecting the performance.
The rotating column is driven by a drive component, which in turn drives two guides to perform mirror reciprocating motion. The motor output torque is amplified by a reduction gearbox. The guides are slidably connected to the guide rail shaft and slidably engaged with the annular guide groove. The guides are made of flexible material to avoid leaving large clearances.
It achieves noiseless and stable reciprocating motion, extending the service life of the equipment and improving the stability and flexibility of the motion.

Description
Technical Field
[0001] The utility model relates to the technical field of motion devices, in particular to a mirror image reciprocating motion device. Background Art
[0002] The mirror reciprocating motion machine is a device that can produce mirror motion. For example, it can produce left-right or up-down symmetrical reciprocating motion. This kind of motion machine can be applied in many fields. For example, it has a very positive effect on the rehabilitation of patients with stroke. Compared with the traditional unilateral motion device, the mirror reciprocating motion device can synchronously train the patient's affected side according to the patient's healthy side information, making full use of the patient's self-assessment ability and his own force perception ability, avoiding the hidden danger of injury to the patient's affected limb when training the unilateral motion device.
[0003] However, most of the existing mirror image reciprocating motion devices adopt unidirectional reciprocating motion in the vertical direction, and the moving parts of this type of motion device are all mounted on the outer shell. Devices with this structure must reserve a relatively large fitting clearance to achieve smooth reciprocating motion. However, if a large fitting clearance is reserved, it will not only easily generate loud noise, but also accelerate the wear between the structures, affecting the actual use effect.

[0011] Furthermore, a guide rail shaft is arranged on the inner wall of the shell, and the two guide members are both slidably connected to the guide rail shaft.

[0018] Furthermore, one end of each guide member close to the corresponding annular guide groove is crescent-shaped, and one end of each guide member close to the corresponding annular guide groove is slidably matched with the annular guide groove.
[0019] Through the above technical solution, smooth reciprocating motion can be achieved without reserving a large fitting gap, and one end of the guide member that slides with the annular guide groove is made of flexible material, which will not produce loud noise and can also delay wear and tear, thereby extending the service life of the mirror reciprocating motion device.
