DETAILED DESCRIPTION

[0040] The preferred embodiments of the present application will be described in detail with reference to the drawings, so that the advantages and features of the present application can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation of the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0041] In this paper, the terms "upper", "lower", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings based on the vehicle in the unfolded state, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0042] Figures 1 to 5 The drawings are drawn to scale, and in order to maintain the brevity of the specification, the proportions of the elements are not listed one by one, but the proportions and positions of the elements should be considered as part of the content of the specification.

[0043] Referring to Figures 1 to 5 A vehicle is shown, which has an unfolded state and a folded state, and the vehicle has a foldable carrying body, which mainly provides carrying support, such as for children to ride or for placing articles, etc.

[0044] The bearing main body comprises a frame assembly, a connecting frame assembly and a support assembly. The frame assembly comprises a first frame 1 and a second frame 2 arranged oppositely, and one end of the first frame 1 is rotatably connected to one end of the second frame 2. The connecting frame assembly comprises a first connecting frame 3 and a second connecting frame 4, one end of the first connecting frame 3 is rotatably connected to one end of the second connecting frame 4, the other end of the first connecting frame 3 is rotatably connected to the first frame 1, and the other end of the second connecting frame 4 is rotatably connected to the second frame 2. The support assembly comprises a first support 5 and a second support 6, one end of the first support 5 is rotatably connected to the first connecting frame 3, and one end of the second support 6 is rotatably connected to the second connecting frame 4.

[0045] In the unfolded state, the first frame 1 and the second frame 2 are unfolded oppositely, and the first connecting frame 3 and the second connecting frame 4 are unfolded oppositely below the first frame 1 and the second frame 2, so that a containing space is formed between the frame assembly and the connecting frame assembly. By arranging a cloth cover or other supporting components in the containing space, the child or the article can be carried. The first support 5 and the second support 6 extend in the up-down direction and are supported below the connecting frame assembly. When the carrier is in the folded state, the first frame 1, the second frame 2, the first connecting frame 3 and the second connecting frame 4 are folded and located between the first support 5 and the second support 6, so that the folded carrier structure is very compact and flat.

[0046] Specifically, one end of the first frame 1 is rotatably connected to one end of the second frame 2 about a first center line X1, one end of the first connecting frame 3 is rotatably connected to one end of the second connecting frame 4 about a second center line X2, the second center line X2 is parallel to the first center line X1, and the second center line X2 is located directly below the first center line X1. In the unfolded state, the first frame 1 and the second frame 2 extend in the first direction and extend in the same horizontal direction. The connecting frame assembly has two groups of connecting frames spaced apart in the second direction, and each side of the first connecting frame 3 and the second connecting frame 4 extends in the up-down direction and is located below the first frame 1 and the second frame 2. Each group of connecting frame assemblies and the first frame 1 and the second frame 2 form a triangle, and the first direction and the second direction are perpendicular to each other, corresponding to the length direction and the width direction of the bearing main body. In the process of converting from the unfolded state to the folded state, the first center line X1 and the second center line X2 move downward and the distance between them gradually decreases, so that the first frame 1, the second frame 2, the first connecting frame 3 and the second connecting frame 4 are folded, and the first frame 1 and the second frame 2 are folded between the first connecting frame 3 and the second connecting frame 4.

[0047] The first linkage structure is capable of driving one of the first frame 1 and the first support 5 to rotate relative to the first connecting frame 3 when the other one rotates relative to the first connecting frame 3, so as to make the first frame 1, the first connecting frame 3 and the first support 5 fold towards each other; the second linkage structure is capable of driving one of the second frame 2 and the second support 6 to rotate relative to the second connecting frame 4 when the other one rotates relative to the second connecting frame 4, so as to make the second frame 2, the second connecting frame 4 and the second support 6 fold towards each other. In this way, when the carrier is folded, only the first frame 1 and the second frame 2 need to be driven to rotate and fold towards each other, or the first support 5 and the second support 6 need to be driven to move towards each other, so as to make each rod of the carrier body rotate and fold towards each other.

[0048] In the embodiment, the carrier body further comprises a first connecting rod 7 and a second connecting rod 8, the first connecting rod 7 is rotatably connected between the first frame 1 and the first support 5, and the second connecting rod 8 is rotatably connected between the second frame 2 and the second support 6, so that the first frame 1, the first connecting rod 7, the first connecting frame 3 and the first support 5 form a four-bar linkage mechanism, and the second frame 2, the second connecting rod 8, the second connecting frame 4 and the second support 6 form another four-bar linkage mechanism. When the first frame 1 and the first connecting frame 3 move towards each other, the first support 5 can be driven by the first connecting rod 7 to move towards the second support 6; when the second frame 2 and the second connecting frame 4 move towards each other, the second support 6 can be driven by the second connecting rod 8 to move towards the first support 5. The first connecting rod 7 not only serves as the first linkage structure to drive the first frame 1 and the first support 5 to rotate relative to the first connecting frame 3 simultaneously during unfolding and folding of the carrier, but also serves as an auxiliary support between the first support 5 and the first frame 1, so that the structure of the carrier body is more stable when the carrier is in an unfolded state; similarly, the second connecting rod 8 not only serves as the second linkage structure to drive the second frame 2 and the second support 6 to rotate relative to the second connecting frame 4 simultaneously during unfolding and folding of the carrier, but also serves as an auxiliary support between the second support 6 and the second frame 2.

[0049] In the embodiment, referring to the drawings, the connecting position c of the first connecting rod 7 on the first frame 1 is closer to the second frame 2 than the connecting position a of the first connecting frame 3 on the first frame 1, the connecting position g of the second connecting rod 8 on the second frame 2 is closer to the first frame 1 than the connecting position e of the second connecting frame 4 on the second frame 2; the rotating position d between the first connecting rod 7 and the first support 5 is below the rotating connecting position b between the first support 5 and the first connecting frame 3; the rotating connecting position h between the second connecting rod 8 and the second support 6 is below the rotating connecting position f between the second support 6 and the second connecting frame 4. This also makes the first connecting rod 7 and the first connecting frame 3 cross each other, and the second connecting rod 8 and the second connecting frame 4 cross each other, playing a reinforcing role on the side of the accommodation space; at the same time, this also makes the angle between the first connecting rod 7 and the horizontal plane and the angle between the second connecting rod 8 and the horizontal plane both be about 90°±10° when the carrier is in the unfolded state, that is, the first connecting rod 7 and the second connecting rod 8 are both in an approximately vertical state when the carrier is in the unfolded state, which makes the carrier have good load-bearing performance in the unfolded state.

[0050] The carrier of the embodiment is a multifunctional vehicle, which further comprises a first wheel assembly 20 arranged at the lower part of the first support 5 and a second wheel assembly 30 arranged at the lower part of the second support 6, and the carrier is supported on the ground and walks by the first wheel assembly 20 and the second wheel assembly 30 in the unfolded state. During the process of converting the carrier from the unfolded state to the folded state, the first wheel assembly 20 and the second wheel assembly 30 approach each other gradually and make the folded carrier stand on the ground by the first wheel assembly 20 and the second wheel assembly 30.

[0051] The carrier further comprises a push-pull frame 9, one end of the push-pull frame 9 is rotatably connected to the second support 6 around the rotating center line X0, and a connecting structure is further arranged between the push-pull frame 9 and the carrier body, and the connecting structure is arranged at intervals with the rotating center line X0 in the length extension direction of the push-pull frame 9.

[0052] In the embodiment, the connecting structure is detachably connected between the push-pull frame 9 and the carrier body, so that when the push-pull frame 9 is connected to the carrier body through the connecting structure, the push-pull frame 9 is fixed relative to the carrier body, and the user can push the push-pull frame 9 to drive the carrier to walk, at this time the carrier is used as a cart; when the connecting structure is not connected to the push-pull frame 9 and the carrier body, the push-pull frame 9 can rotate around the rotating center line X0, and the user can pull the push-pull frame 9 to drag the carrier to walk, at this time the carrier is used as a trailer.

[0053] In this embodiment, the connecting structure is arranged between the second frame 2 and the push-pull frame 9, and the push-pull frame 9 is rotatably connected to the second frame 2 through the connecting structure. During the conversion of the carrier from the unfolded state to the folded state, the second frame 2 and the second support 6 are respectively folded relative to the push-pull frame 9, that is, the push-pull frame 9 is rotatably connected to the second frame 2 through the connecting structure, and the push-pull frame 9 is also rotatably connected to the rod in the carrier body to jointly participate in the folding of the carrier. In other embodiments, the connecting structure can also be arranged to slide relative to the push-pull frame 9. When the carrier is converted from the unfolded state to the folded state, the push-pull frame 9 remains connected to the carrier body, and the second frame 2 drives the connecting structure to slide along the length extension direction of the push-pull frame 9, so that the push-pull frame 9 is folded relative to the second frame 2. Of course, in some other embodiments, the push-pull frame 9 can be first separated from the carrier body, and then the push-pull frame 9 is folded with the folded carrier body, and the connecting structure is connected to fix the push-pull frame 9 on one side of the carrier body.

[0054] Here, the push-pull frame 9 includes a lower push rod 91 and an upper push rod 92, and a handle rod 93 fixed to the top of the upper push rod 92. The lower push rod 91 and the upper push rod 92 both extend in the up-down direction and are slidably connected. The lower part of the lower push rod 91 is rotatably connected to the second support 6 about the rotation center line X0, and the upper push rod 92 can slide through the rod cavity of the lower push rod 91 along the length direction of the upper push rod 92, so that the length of the push-pull frame 9 is as small as possible. The connecting structure is a connecting piece 10 slidably arranged on the upper part of the lower push rod 91. The connecting piece 10 has a clamping part 101 capable of being clamped on the second frame 2. The clamping part 101 can also rotate relative to the second frame 2 after being clamped on the second frame 2. In other embodiments, the connecting structure can be arranged on the push-pull frame to be detachably connected with the second frame 2.
