The front leg foldable frame shown in fig. 1-10 has a foldable state and an unfolded state, and comprises a handrail frame 1, a front leg frame 2, a front wheel frame 3, a bottom frame 4 and a rear leg frame 10 which can be mutually folded or unfolded, and a first connecting member 5, wherein the first connecting member 5 is respectively hinged with the front leg frame 2 and the front wheel frame 3, the bottom frame 4 is respectively hinged with the front leg frame 2 and the front wheel frame 3, the handrail frame 1 is hinged with one end of the front leg frame 2 far away from the front wheel frame 3, and the rear leg frame 10 is respectively hinged with the handrail frame 1 and the bottom frame 4. The first connecting piece 5, the front foot rest 2, the front wheel frame 3 and the underframe 4 form a frame front foot folding structure. The first connecting member 5 enables the front wheel frame 3 to be folded downwards relative to the bottom frame 4 when the handrail frame 1 drives the front foot frame 2 to be folded downwards.

Specifically, when the armrest frame 1, the front foot frame 2, the front wheel frame 3, the bottom frame 4 and the rear foot frame 10 are folded, the first connecting member 5 enables the front wheel frame 3 to be folded downward relative to the bottom frame 4.

Specifically, when the armrest frame 1, the front foot frame 2, the front wheel frame 3, the bottom frame 4 and the rear foot frame 10 are unfolded, the first connecting member 5 enables the front wheel frame 3 to be turned upwards and unfolded relative to the bottom frame 4.

In summary, when the frame is folded, the front wheel frame can be folded relative to the underframe when the front foot stool is folded through the front foot stool folding structure of the frame, so that the folded frame is more compact and occupies less space.

Further, as a preferred embodiment of the present invention, but not limited thereto, a sliding rod 6 is hinged on the first connecting member 5, a strip-shaped hole 31 for inserting the sliding rod 6 is formed on the front wheel frame 3, and the sliding rod 6 slides along the strip-shaped hole 31 when the front wheel frame 3 is folded and turned downward relative to the bottom frame 4. The arrangement realizes that the first connecting piece 5 enables the front wheel frame 3 to be downwards overturned and folded relative to the bottom frame 4 when the handrail frame 1 drives the front foot frame 2 to be downwards overturned and folded, and the structure is simple and the implementation is convenient.

Further, as a preferred embodiment of the present invention, but not limited thereto, a positioning mechanism 9 is provided between the front foot frame 2 and the front wheel frame 3, and the positioning mechanism 9 restricts the front foot frame 2 from being tilted up with respect to the front wheel frame 3 after the front foot frame 2 and the front wheel frame 3 are tilted up and unfolded into position. This arrangement enables the front foot rest 2 and the front wheel frame 3 to be positioned after being unfolded in place.

Specifically, the positioning mechanism 9 includes a second inserting portion 92 disposed on the front foot rest 2 and an inserting groove 91 disposed on the front wheel frame 3, and the inserting groove 91 and the second inserting portion 92 are engaged with each other after the front foot rest 2 and the front wheel frame 3 are unfolded in place. The arrangement realizes the positioning of the front foot stool 2 and the front wheel frame 3, and has simple structure and convenient implementation.

Further, as a preferred embodiment of the present invention, but not limited thereto, a locking mechanism 8 is provided between the armrest frame 1 and the front foot frame 2, and the locking mechanism 8 locks the armrest frame 1 and the front foot frame 2 after the armrest frame 1, the front foot frame 2, and the front wheel frame 3 are folded up and unfolded in place. This arrangement achieves locking of the front foot frame 2 and the armrest frame 1 after deployment in place.

Specifically, the locking mechanism 8 includes a first insertion portion 81 disposed on the armrest frame 1 and capable of moving relative to the armrest frame 1, and an insertion hole 82 disposed on the front foot frame 2, wherein the insertion hole 82 and the first insertion portion 81 are inserted and matched after the armrest frame 1, the front foot frame 2 and the front wheel frame 3 are flipped up and unfolded in place. The arrangement realizes the locking of the front foot rest 2 and the handrail frame 1, and has simple structure and convenient implementation.

Further, as a preferred embodiment of the present invention, but not limited thereto, a second connecting member 7 is fixedly connected to the base frame 4, and the second connecting member 7 is hinged to the front foot frame 2 and the front wheel frame 3, respectively. As can be seen, in the expanded state, the second link 7 is in surface contact with the front frame 2 and the front wheel frame 3. This arrangement can improve the tightness of the assembly of the second connecting member 7 with the front foot frame 2 and the front wheel frame 3.

Further, as a preferred embodiment of the present invention, but not limited thereto, a positioning surface (not shown) is formed on the second connecting member 7, and abuts against the first connecting member 5 after the front foot stool 2 and the front wheel frame 3 are folded up and unfolded into position. This arrangement can improve the stability of the rotation, and prevent the first connecting member 5 from excessively rotating.

Further, as a preferred embodiment of the present invention, but not limited thereto, the second connector 7 is formed with a positioning groove 72 into which the chassis 4 is inserted. This arrangement can improve the stability of the connection.
