Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0029] The following further describes the present utility model in detail with reference to the accompanying drawings:

[0030] A walking aid footrest assembly 3, as Figures 1-4 shown, includes a base 33, a curved rod 31, and a pedal 32. The pedal 32 is installed at one end of the curved rod 31, and a connecting member 312 is provided at the other end of the curved rod 31. A sliding groove 331 is provided on the side wall of the base 33, and a limiting groove 332 extending downward is provided on the sliding groove 331; the connecting member 312 is rotatably installed inside the base 33; a sliding block 311 matching with the sliding groove 331 is provided on the side wall of the connecting member 312.

[0031] When rotating the connecting member 312 and the curved rod 31, the sliding block 311 moves in the sliding groove 311 to fold the curved rod 31 and the pedal 32; when the sliding block 311 enters the limiting groove 332, the rotation angle of the curved rod 31 is restricted, facilitating stepping on the pedal 32; when the curved rod 31 is pulled upward, the curved rod 31 can be rotated again. The folding of the footrest assembly can be conveniently performed.

[0032] An activity groove 333 is provided inside the base 33, and a return spring 335 is provided in the activity groove 333; one end of the return spring 335 is connected to the base 33, and the other end is connected to the connecting member 312. When the curved rod 31 rotates to the limiting groove 322, the sliding block 311 enters the limiting groove through the return spring 335, and the gear can be automatically locked. The return spring 335 provides an operating damping and a force for the curved rod to return to the locked gear.

[0033] Among them, limiting grooves 332 extending downward are respectively provided on both sides of the sliding groove 331, corresponding to the footrest gear and the folding gear (not shown in the figure). A reinforcing rod can also be provided on the curved rod.

[0034] In a specific design, a V-shaped spring buckle 313 is further provided on the lower side of the connecting member 312, and the free end of the V-shaped spring buckle 313 extends towards the sliding groove 331, which can play a role in rotational limiting.

[0035] As Figure 1 and Figure 4, one end of the curved rod 31 is provided with a mounting member 321, one side of the pedal 32 is provided with a hinge member 322, and the hinge member 322 is hinged on the mounting member 321; a limiting boss 323 that cooperates with the pedal 32 is provided on the lower side of the mounting member 321. The pedal 32 can be folded simultaneously.

[0036] As Figure 5 , the base 33 is mounted on the front fork 13 of the walking aid 1. A mounting seat 131 is provided at the front end of the front fork 13, and the base 33 is fixed on the mounting seat 131. More specifically, the walking aid 1 further includes a support frame 11, a handle 12 is provided on the upper side of the support frame 11; a first support rod 21 is provided on the support frame 11, a folding armrest assembly 2 and a second support rod 22 are provided on the front side of the first support rod 21, and the front fork 13 is mounted at the front end of the second support rod 22; driving wheels 14 are respectively provided on the lower side of the front fork 13 and the lower side of the support frame 11.

[0037] The present invention solves the problems of complex footrest storage operation and exposure of the mounting structure, and can conveniently fold the footrest assembly and the pedal. The curved rod and the pedal are folded to one side of the walking aid. The folding operation method is: pull up the curved rod and rotate it to one side, release it after rotating to the end, and the footrest automatically falls into the locked gear. The connecting member 312 is provided with a certain rotation angle, and a greater distance between the driving wheel 14 and the pedal 32 can be obtained after folding, avoiding interference between the pedal 32 and the driving wheel 14.

[0038] The rotation angle range of the curved rod is 80 - 160°, and the preferred angle is 135°; the rotation angle range of the pedal is 80 - 90°, and the preferred angle is 85°, but it is not limited thereto.

[0039] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
