[0002] A camper, also known as a beach cart or a portable outdoor cart, is a foldable handcart. It is widely used in family life because of its small size when folded and large loading space when unfolded. It is often used in outdoor leisure and entertainment to load various leisure and entertainment and daily necessities. It is also used in people's daily life such as setting up stalls on the street and moving short distances.

[0003] As the use scope and application areas of camper vans continue to expand, camper van design manufacturers have designed and produced camper vans with more styles and more novel shapes to meet their greater usage needs.

[0004] However, the frame structure of camper in the prior art generally adopts a matching mode of directly hingedly connecting multiple connecting rods with the base. This means that when designing and manufacturing camper with more styles and more novel shapes, it is necessary to design and manufacture various different bases and their connection modes with connecting rods according to different camper shapes, such as strips, squares, rectangles or other shapes. This increases the update and iteration cost of camper and makes the design and manufacturing versatility of camper frame poor. In addition, the connection between the base and connecting rod of the existing camper frame is easy to loosen, causing the base and connecting rod to separate easily after the camper is used for a period of time. Furthermore, the wheel width of the camper is single, and the wheel width of the camper cannot be adaptively changed according to different use sites. Utility Model Content

[0031] A base 1, arranged at the bottom of the camper; and

[0032] A plurality of connecting members 2 are arranged around the base 1, one end of the plurality of connecting members 2 is hinged to the base 1, the connecting members 2 are used to swing in a horizontal plane, and the other end of the plurality of connecting members 2 is connected one-to-one with a plurality of connecting rods 41 at the bottom of the camper.

[0033] It should be noted that the base 1 here can be an integrally formed part, such as a shell structure, a spherical structure, or a rectangular structure, as mentioned later in this embodiment, in which a support portion 13 is used to connect the top plate 11 and the bottom plate 12 together, or it can be other structural forms, as long as it can be hinged with multiple connecting parts 2 and allow the connecting parts 2 to swing in a horizontal plane.

[0034] In addition, the connecting member 2 and the connecting rod 41 here can be hinged or fixedly connected, as long as the use requirements of the camping vehicle for the connecting rod 41 and the connecting member 2 can be met.

[0035] In this embodiment, a plurality of connecting members 2 are arranged around the base 1, and the connecting members 2 are hinged to the base 1, so that the connecting members 2 can swing relative to the base 1 in a horizontal plane. In the process of connecting the connecting rod 41 connected to the connecting member 2 with the frame 42 of the camper, the position of the connecting rod 41 relative to the frame 42 can be adjusted according to different shapes of the camper. For example, for a long camper, the connecting member 2 swings in the horizontal plane, so that the angle between the two connecting rods 41 located at the front or rear of the vehicle can be smaller, so as to ensure that the corners of the connecting rod 41 and the frame 42 can be smoothly connected. For a square or round camper, the connecting member 2 swings in the horizontal plane, so that the angle between the two adjacent connecting rods 41 is larger and more uniform than the above-mentioned situation of the long camper. Therefore, the seat body connection structure in this embodiment can meet the design and manufacturing needs of various different camper shapes. Thereby improving the versatility of design and manufacturing of the frame 42 of the camper, and reducing the update and iteration cost of the camper.

[0036] Furthermore, the base 1 includes a top plate 11 and a bottom plate 12, the top plate 11 and the bottom plate 12 are arranged at a distance, one end of the connecting member 2 is clamped between the top plate 11 and the bottom plate 12, and one end of the connecting member 2 is hinged to the top plate 11 and the bottom plate 12 respectively.

[0037] The plate-like structure is used to reduce the volume of the base 1 and ensure the hinge strength of the multiple connecting members 2.
