When the knee protector is used by a user, the shifting block is shifted to drive the second knee protecting ring to slide, and when the shifting block reaches the right end (left end) of the window, the magnetic sheet on the shifting block and the magnetic sheet on the window are attracted to lock the first knee protecting ring and the second knee protecting ring, so that the knee is wrapped; when the knee protection component is not used, the poking block is poked reversely, the second knee protection ring automatically shrinks into the interlayer under the action of the spring, and the knee protection component returns to the opening state.

In addition, the elastic member 15 can be omitted in the above-described aspect, and the closing and opening of the knee pad assembly can be similarly achieved.

Referring to fig. 10, the knee protecting assembly includes a first knee protecting ring 11 and a second knee protecting ring 12, the right end of the first knee protecting ring 11 is connected with the left end of the second knee protecting ring 12, and when the left end of the first knee protecting ring 11 is connected with the right end of the second knee protecting ring 12, the knee protecting assembly is in a closed state; when the left end of the first knee bolster 11 is disconnected from the right end of the second knee bolster 12, the knee pad assembly is in an open state.

The right end of the first knee protection ring 11 and the left end of the second knee protection ring 12 can be connected in a rotatable connection mode through a sliding rod, a bearing and the like.

The left end of the first knee protection ring 11 is movably connected with the right end of the second knee protection ring 12, for example, a snap-in type, a latch type, a nested type, etc.

Of course, the knee pad assembly may be provided with only the first knee pad ring, which is shaped to fit the knee region of the human body.

To be more ergonomic and to prevent injury to the user from the shaking of the lower leg during standing, the knee pad assembly can have a certain angle of inclination.

Referring to fig. 11, a walking aid device (only a part of which is shown) using the adjustable knee protecting device of the previous embodiment is fixed with the stepping training unit 3 unit in the walking aid device.

Different quantities of knee protection devices can be arranged according to actual requirements in the using process. For example, in the stepping rehabilitation training, the knee protection devices and the stepping plates are symmetrically arranged at the left and right sides, and the knee protection devices can be adjusted at multiple angles and have a large adjustable range, so that when a user needs to exercise, the left and right pedals and the knee protection devices are controlled by the braking device to alternately move up and down, back and forth and left and right, so that the lower limbs of the user are driven to reciprocate, and the purpose of stepping rehabilitation training is achieved.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for the person skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, which all fall within the protection scope of the present invention.
