The EMS circuit does not need to set up other circuit structures, which simplifies the overall structure, reduces the production cost of the product, and improves the durability and safety of the EMS circuit of the product during exercise.

[0036] In this embodiment, please refer to Figure 1 The shell includes a base 101, a mounting seat 102 and an upper cover 103 which are connected in sequence; the working unit 500 is movably connected to the base 101, and the driving member 300 and the transmission assembly are installed on the mounting seat 102; the upper cover 103 covers the mounting seat 102 to protect the driving member 300 and the transmission assembly.

[0037] In one embodiment of the present application, please refer to Figure 2 and Figure 3 The transmission assembly includes an input gear 401, a transmission gear and multiple output gears 405; the input gear 401 is connected to the driving member 300; the transmission gear is meshed with the input gear 401; the multiple output gears 405 are respectively meshed with the transmission gears, and the output gears 405 are arranged in a one-to-one correspondence with the working units 500.

[0038] In this embodiment, the multiple output gears 405 are all meshed with the transmission gear, so that the transmission gear can drive the multiple output gears 405 to rotate synchronously. The output gears 405 and the working units 500 are arranged one by one, so that the multiple working units 500 can move synchronously.

[0039] In this embodiment, the transmission gear includes a plurality of reduction gears meshing in sequence. By providing a plurality of reduction gears, the rotation speed of the transmission component can be reduced and the output torque of the transmission component can be increased.

[0041] In this embodiment, by providing conductive spring pins and fixing hardware, the main board 200 and the output gear 405 can always maintain an electrically conductive state; the conductive spring pins are electrically connected to the fixing hardware, thereby reducing the circuit interruption phenomenon caused by the rotation of the output gear 405. For example, the fixing hardware can be a bearing, the inner ring of the bearing is connected to the rotating shaft of the output gear 405, and the outer ring of the bearing is electrically connected to the conductive spring pin; the bearing and the rotating shaft are both made of conductive materials.

[0042] In one embodiment of the present application, the fixing hardware of the two output gears 405 are electrically connected via a wire (not shown).

[0050] It is understandable that the eccentric column 451 is a columnar structure protruding from the cross section of the output gear 405 and has a certain distance from the rotation center of the output gear 405. The output gear 405 is made of conductive plastic material, such as POK material.
