[0013] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Embodiment 1:

[0015] refer to Figures 1 to 4A walker that is easy to fold includes a frame body 1 and wheels 2. The frame body includes a left front leg tube 111 and a right front leg tube 121, a left rear leg tube 131 and a right rear leg tube 141. The left front leg tube, the right front leg tube, the left rear leg tube and the right rear leg tube are supported on the wheels respectively, wherein the left front leg tube 111 and the left rear leg tube 131 are hinged, the right front leg tube 121 and the right rear leg tube 141 are hinged, the left front leg tube 111 and the right front leg tube 121 are fixed together by a cross bar to form a front frame body 13, and the left rear leg tube 131 and the right rear leg tube 141 are fixed together by a connecting rod. The rear frame 14 is formed by the seat cushion 5, which is rotatably mounted on the front frame. The walking aid vehicle further comprises a left first folding piece 3 and a left second folding piece 4 which are hinged together. The left first folding piece is rotatably mounted on the front frame 13, and the left second folding piece is rotatably mounted on the rear frame 14. The left first folding piece extends a first lever 31. When the seat cushion 5 rotates, the first lever drives the left first folding piece to rotate, so that the left first folding piece performs a folding action relative to the left second folding piece, pulling the front frame 13 and the rear frame 14 to fold, so that the walking aid vehicle is in a folded state. The left second folding piece is provided with a limit piece for limiting its opening angle relative to the left first folding piece. The walker also includes a right first folding piece 6 and a right second folding piece 7 which are hinged together. The right first folding piece is rotatably mounted on the front frame 13, and the right second folding piece is rotatably mounted on the rear frame 14. When the right first folding piece and the right second folding piece are folded, the front frame 13 and the rear frame 14 are pulled to fold. The right first folding piece extends a second lever 61, and the second lever is connected to the first lever through a connecting rod 8. When the seat cushion 5 rotates in the upright direction, it drives the connecting rod 8 to simultaneously drive the left first folding piece and the right first folding piece to rotate, and they respectively fold relative to the left second folding piece and the right second folding piece, pulling the front frame 13 and the rear frame 14 to fold, so that the folding and folding of the walker is more stable. The seat cushion 5 of the utility model is in a flat state when the frame body is opened. When the seat cushion 5 rotates from the flat state to the vertical direction, it is linked with the folding of the frame body, which greatly facilitates the folding of the walker. The right second folding piece of the walker is provided with a limit piece 71 for limiting its opening angle relative to the right first folding piece. The right second folding piece is provided with a locking column 72. The right first folding piece is equipped with a sheet-shaped vehicle collection hook 62 with elasticity. When the right first folding piece and the right second folding piece are folded to a predetermined position, the vehicle collection hook can be locked on the locking column. The end of the vehicle collection hook is provided with an introduction part 621 with an inclined surface. When the right first folding piece is folded to a predetermined position relative to the right second folding piece, the introduction part guides the locking column into the locking position of the vehicle collection hook, so that the vehicle collection hook is conveniently locked on the locking column, so that the walker is in a stable folded state.

[0016] Example 2

[0017] refer to Figure 5The difference between Example 2 and Example 1 is that Example 2 adds a flexible cloth bag 9.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
