Example Embodiment
[0018] Example 1:
[0019] Such as figure 1 As shown, the present invention includes a prosthetic foot plate 1, an ankle joint 2 arranged on the top surface of the prosthetic foot plate 1, and a calf prosthesis 3 fixedly connected to the ankle joint 2, and may also include a prosthetic foot plate 1 的脚套4.
[0020] The prosthetic foot board 1 of the present invention includes an upper foot board 11 and a heel elastic sheet 12 made of carbon fiber board. The front part of the heel elastic sheet 12 is fixedly connected to the middle of the bottom surface of the upper foot board 11, and the rear part of the heel elastic sheet 12 is between the upper foot board 11. There is a space for elastic activity, and the front part of the upper foot plate 11 and the lower surface of the heel elastic sheet 12 are both provided with a wear-resistant layer. The prosthetic foot board 1 of the present invention can also adopt other existing technology foot boards, or foot boards made of other structura...
Example Embodiment
[0025] Example 2:
[0026] Such as Figure 5 As shown, this embodiment is basically the same as embodiment 1, and its difference from embodiment 1 is that in the swing frame 23, a magnetorheological fluid tank 32 is provided on the other side of the reducer 24 opposite to the motor 26. The magnetorheological fluid tank 32 is provided with a magnetorheological fluid, and an impeller 33 is immersed in the magnetorheological fluid. The rotating shaft of the impeller 33 passes through the magnetorheological fluid tank 32 and is connected to the output shaft of the incomplete gear 31. Around the rotating shaft of the impeller 33, a coil 34 connected to the power supply device is provided outside the magnetorheological fluid tank 32.
[0027] In the foregoing embodiments, the motor 26 has an independent power supply device, and the output end of the motor 26 can rotate in a forward or reverse direction. In addition, in addition to the above-mentioned structure, the number of reduction ...
