The cross-bracing assembly between the brackets 100, the side brackets 100 on each side includes a plurality of bracket bars that can be relatively rotatably connected. When the cart frame is in a folded state, the plurality of bracket bars on each side bracket 100 are rotated and folded together. Afterwards, the side brackets 100 on both sides can be respectively turned over relative to the cross brace assembly to realize the lateral folding of the cart frame.

The cart frame also includes an armrest frame 9 . The armrest frame 9 includes two armrest bars 91 respectively arranged on the left and right sides and extending in the front-rear direction, and an armrest cross bar 92 connected between the front portions of the two armrest bars 91 . , the end of the armrest cross bar 92 and the armrest bar 91 are rotatably connected by the armrest rotating shaft 93, and the armrest bars 91 can be respectively arranged in a vertical direction opposite to the side brackets 100 to be turned and folded. When the cart frame is folded, the handrail bar 91 is first folded with the side bracket 100 on the same side, and then the handrail bar 91 on both sides is turned over and retracted relative to the handrail cross bar 92 around the handrail rotation axis 93 with the turning of the side bracket 100 relative to the cross brace assembly. Folding, the cart frame with armrest frame 9 can be folded horizontally.

Specifically, referring to the drawings, in this embodiment, the side brackets 100 on each side at least include a front support rod 1 , a rear support rod 2 , a side link 3 , a push rod 4 , and a rear connecting rod extending in the up-down direction. The rod 5, and the bottom link 6 extending in the front-rear direction, the upper part of the front support rod 1, the upper part of the rear support rod 2 and the lower part of the side link 3 are mutually rotatably connected by a rotating joint 10, and the side link The upper part of the rear link 5 is pivotally connected to the push rod 4, the upper part of the rear link 5 is pivotally connected to the lower part of the push rod 4, and the lower part of the rear link 5 is pivotally connected to the rear support rod 2, and its lower part also has a rearward The front part of the extension part 5a is pivotally connected to the rear part of the bottom link 6 , and the front part of the bottom link 6 is pivotally connected to the front pole 1 .

On the left and right sides of the cart frame, the rear part of the handle bar 91 is pivotally connected to the rear link 5 , and a sliding member 94 is rotatably provided on the side link 3 , and the sliding member 94 extends along the length of the handle bar 91 . The direction sliding is provided on the handrail 91 , and the sliding member 94 here is a sliding sleeve slidably sleeved on the handrail 91 . When the cart frame is folded, the rear link 5 and the side link 3 in each side bracket 100 are folded relative to each other, so that the armrest bar 91 opposite the side link 3 and the rear link 5 are turned upward and folded in the side link Front side of rod 3.

The side brackets 100 on each side also include a seat post 7 extending in the front-rear direction, the seat post 7 being located below the arm bar 91, the rear portion of the seat post 7 is pivotally connected to the rear link 5, and the seat post 7 is slidably on A sliding sleeve 8 is provided, and the sliding sleeve 8 is pivotally connected to the side link 3 . When the cart frame is folded, the rear link 5 in each side bracket 100 and the side link 3 are folded relative to each other, which also drives the seat post 7 to be turned upward and folded with the side link 3 .

Referring to the drawings, the cross-bracing assembly includes a plurality of cross-bracing rods extending in the left-right direction, including cross-bracing rods 21 provided between the lower parts of the front support rods 1 on both sides, and rear support rods 2 provided on both sides. The transverse strut 22 between the lower parts, the transverse strut 23 between the lower parts of the rear connecting rods 5 on both sides, the transverse strut 24 between the upper parts of the push rods 4 on both sides, the transverse strut 21/22/ One end of 23/24 is pivotally connected to the left side bracket 100 through the first shaft 101 , and the other end of the cross strut 21/22/23/24 is pivotally connected to the right side through the second shaft 102 on the stand 100. When the cart frame is folded, the front strut 1, the rear strut 2, the side link 3, the push rod 4 and the rear link 5 on the same side are rotated and folded relative to each other, as shown in Figure 3, all the first axis The axis lines of the shafts 101 extend collinearly or parallel to each other, and the axis lines of all the second shafts 102 also extend collinearly or parallel to each other.
