[0023] The present invention will now be described in detail with reference to various embodiments. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0024] This invention involves installing an adjustable-width orthopedic leg on an electric wheelchair. The width of the orthopedic leg can be adjusted simply by loosening the adjusting nut on the back of the seat frame. After adjusting to the most comfortable width, the nut can be tightened. When the orthopedic leg is no longer in use, it can be easily detached, resulting in a wheelchair with no external attachments and a more aesthetically pleasing appearance.

[0025] like Figure 1 As shown, one embodiment of this utility model provides an orthopedic leg mechanism 100, which includes an orthopedic leg assembly 10 and a connecting seat 20. The orthopedic leg assembly 10 is a structure that supports the lower limbs of a user undergoing orthopedic surgery. The orthopedic leg assembly 10 is slidably and detachably connected to an electric wheelchair 200 via the connecting seat 20.

[0026] Therefore, when the locking element is released, the orthopedic leg mechanism 100 can be adjusted along its width; and when locked, the orthopedic leg mechanism 100 can be locked and fixed, thereby improving the user's comfort and convenience. Furthermore, the orthopedic leg mechanism 100 of this utility model can also be completely separated from the electric wheelchair 200, so that it can be easily separated and stored when not in use, ensuring the overall aesthetics of the electric wheelchair 200.

[0027] Specifically, one end of the connecting seat 20 can be movably inserted into the electric wheelchair 200 along its width and can be locked by a locking member 30. In one embodiment, one end of the connecting seat 20 is a plug-in member with a guide groove 21; the electric wheelchair 200 has a slot 201 that mates with the plug-in member. In this case, the plug-in member is slidably connected to the slot 201, and the slot 201 has a protruding rib that mates with the guide groove 21. Thus, when the connecting seat 20 slides along the slot 201, the width between the orthopedic leg mechanism 100 and the electric wheelchair 200 can be adjusted.

[0028] like Figure 2 As shown, the orthopedic leg assembly 10 includes: an orthopedic leg 11, a connecting frame 12, and a buckle plate 13.

[0029] The orthopedic leg 11 includes a support 111, a foot pedal 112, and a backrest 113. The foot pedal 112 is pivotally connected to the bottom end of the support 111, and the backrest 113 is pivotally connected to one side of the support 111. In one embodiment, the foot pedal 112 is pivotally connected to the bottom end of the support 111 via a pin, and the backrest 113 is pivotally connected to one side of the support 111 via a hinge. Thus, in use, the foot pedal 112 and the backrest 113 can be flipped out, allowing the user to step on the foot pedal 112 and rest their leg against the backrest 113.

[0030] The connecting frame 12 is mounted on the orthopedic leg 11, and the other end of the connecting seat 20 forms a pivot connection end. At this time, the connecting frame 12 is pivotally connected to the pivot connection end of the connecting seat 20. In one embodiment, the connecting frame 12 is a vertical tube, and two hinges arranged vertically on one side of the vertical tube are pivotally connected to the connecting seat 20. Correspondingly, the connecting seat 20 is provided with hinge holes that mate with the hinges.

[0031] like Figure 3 , 4 As shown, when needed, the orthopedic leg assembly 10 can be pulled out and pivoted to a suitable position. When not in use, the orthopedic leg assembly 10 can be pushed back and pivoted and folded to one side of the electric wheelchair 200. Alternatively, the orthopedic leg assembly 10 can be removed and stored, ensuring the overall aesthetics of the electric wheelchair 200.

[0032] As described above, the connecting seat 20 can be locked by a locking member 30. This facilitates the locking and securing of the orthopedic leg assembly 11 after it has been pulled out to a suitable width. In one embodiment, the locking member 30 is a nut. In this case, the connecting seat 20 is locked to the electric wheelchair 200 by the nut.

[0033] like Figure 5As shown, another embodiment of the present invention also provides an electric wheelchair 300, which includes a frame 301 and an orthopedic leg mechanism 100 as described above. The orthopedic leg assembly 100 is detachably connected to the frame 301 via a connecting seat.

[0034] In summary, the orthopedic leg mechanism of this embodiment can be slidably connected to the electric wheelchair along its width and locked in place by a locking device. Thus, when the locking device is released, the orthopedic leg mechanism can be adjusted along its width; when locked, it is securely attached, thereby improving user comfort and convenience. Furthermore, the orthopedic leg mechanism of this embodiment can also be completely detached from the electric wheelchair, allowing for easy separation and storage when not in use, ensuring the overall aesthetics of the electric wheelchair.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
