The joint angle identification unit 52 is electrically connected to the shooting unit 51, and is used to identify the stepping image to obtain a hip joint angle data, a knee joint angle data and an ankle joint angle data.

In this embodiment, the photographing unit 51 is a full-color camera; the joint angle recognition unit 52 is a computing model generated by training using a deep learning method, which is common knowledge in the relevant field to which the present invention belongs.

It is worth mentioning that the image of the pedal closer to the shooting direction at the bottom dead center position is used as the standard for joint angle judgment.

After the processor unit 42 controls the lifting kit 31 and/or the front-rear displacement kit 32 to move the seat cushion 12 to one of the matching setting positions, and when the user is using the sports device of the present invention, the processor unit 42 synchronously compares the hip joint angle data, the knee joint angle data, and the ankle joint angle data with the corresponding hip joint angle range θ1, knee joint angle range θ2, and ankle joint angle range θ3, respectively. If the comparison results match, no additional action is required; if the comparison results do not match, the lifting kit 31 and/or the front-rear displacement kit 32 are controlled to move the seat cushion 12 to another matching setting position. In this way, the effect of dynamically adjusting the seat cushion setting position during use can be achieved.

Specifically, after the processor unit 42 moves the seat cushion 12 to one of the matching setting positions, the hip joint angle data, the knee joint angle data and the ankle joint angle data are compared with the corresponding hip joint angle range θ1, the knee joint angle range θ2 and the ankle joint angle range θ3 respectively. If the comparison results match, no additional action is required; if the comparison results do not match, the lifting kit 31 and/or the fore-and-aft displacement kit 32 are controlled to move the seat cushion 12 to another matching setting position.
