[0052] The disclosure below provides many different embodiments or examples to realize different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.

[0053] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0054] See also Figure 1 to Figure 6 As shown, the present invention provides a multifunctional camping vehicle, comprising:

[0055] The chassis 100 has a pair of front wheels 110 and a pair of rear wheels 120;

[0056] The folding mechanism 200 is disposed between the front wheel 110 and the rear wheel 120; and

[0057] The top frame 300 is disposed on the bottom frame 100 and is used to form a storage cavity with the folding mechanism 200 as the bottom and the area surrounded by the top frame 300 as the entrance;

[0058] Among them, a pair of support mechanisms 400 arranged at intervals along the width direction are detachably connected to the top frame 300, which are used to install a table top 500 for users to have picnics and entertainment activities; after removing the support mechanism 400, the middle part of the folding mechanism 200 is lifted to fold the two ends of the top frame 300 in the length direction downward, and the front wheels 110 can be retracted between the rear wheels 120 to achieve folding.

[0059] See also Figure 5 and Figure 6As shown, each supporting mechanism 400 includes a first rod 410 and a second rod 420 for placing a table top 500. The first rod 410 and the second rod 420 are connected by a hinge 430 to achieve folding and storage. One end of the first rod 410 away from the hinge 430 is detachably connected to one end of the top frame 300, and one end of the second rod 420 away from the hinge 430 is detachably connected to the other end of the top frame 300. Specifically, the cross-sections of the first rod 410, the second rod 420 and the hinge 430 are all L-shaped structures. The horizontal side of the L-shaped structure constitutes the support part of the bottom surface of the table board 500 to prevent the table board 500 from falling, and the vertical side of the L-shaped structure constitutes the blocking part of the short side of the table board 500 to allow the table board 500 to slide on the support part along the length direction of the top frame 300 and limit the movement of the table board 500 along the width direction of the top frame 300; the hinge 430 can make the first rod 410 and the second rod 420 located at the same height plane when unfolded, and when the ends of the first rod 410 and the second rod 420 are in contact with each other, it can limit their further downward rotation and folding. Through the hinge 430, the stability of the connection between the first rod 410 and the second rod 420 can be effectively ensured, so that the support mechanism 400 can be kept in a horizontally unfolded state, thereby achieving stable support for the table board 500. Of course, in other embodiments, the support mechanism 400 may also have three or four or more rods extending along the length direction of the top frame 300, and any adjacent rods are hingedly connected to make the size of the support mechanism 400 smaller after storage.

[0060] When in use, the user can directly use the camper as a supporting carrier, and then set up the table top 500 between a pair of supporting mechanisms 400 for use. The assembly is simple and convenient, and the amount of camping tools carried can also be reduced. Moreover, the detachable supporting mechanism 400 does not affect the folding of the camper, and is highly practical. After folding, the front wheels 110 can be stored between the rear wheels 120, occupying a small volume and providing a good user experience.

[0061] In this embodiment, the first rod 410 and the second rod 420 have the same structure, and their length is greater than the width of the table top 500, so as to facilitate the placement of multiple table tops 500. Specifically, in order to improve the adaptability between the table top 500 and the support mechanism 400 and reduce the production cost to improve the promotion of the camper, the table top 500 is a standardized component with a width of about 250 mm; the length of the first rod 410 and the second rod 420 is about 375 mm, and the length after being connected by a pair of hinges 430 is about 756 mm, so three table tops 500 can be placed between the pair of support mechanisms 400 at the same time.

[0062] See also Figure 5 and Figure 6As shown, the end of the first rod 410 away from the hinge 430 is connected to the first connector 440, the first connector 440 is provided with a first plug connector 441 and a first plug board 442 connected thereto, and the first plug board 442 is plug-connected to the first plug slot 301 set at one end of the top frame 300; the end of the second rod 420 away from the hinge 430 is connected to the second connector 450 which is symmetrical with the first connector 440, the second connector 450 is provided with a second plug connector 451 and a second plug board 452 connected thereto, and the second plug board 452 is plug-connected to the second plug slot 302 set at the other end of the top frame 300; the first plug connector 441 and the second plug connector 451 are arranged opposite to each other, and are used to block the long side of the table top 500 to limit the sliding of the table top 500 on the support portion. After unfolding the support mechanism 400, the first plug-in board 442 is inserted into the first plug-in slot 301, and the second plug-in board 452 is inserted into the second plug-in slot 302, so that the support mechanism 400 can be quickly installed on the top frame 300, and the table top 500 can be placed in between for use; when the camping car needs to be folded, the table top 500 is folded, and the support mechanism 400 is pulled up to disengage the first plug-in board 442 from the first plug-in slot 301, and the second plug-in board 452 from the second plug-in slot 302 to complete the disassembly of the support mechanism 400.

[0063] The top frame 300 includes a first C-shaped frame 310 and a second C-shaped frame 320 with the same structure. The first C-shaped frame 310 and the second C-shaped frame 320 are connected by a pair of adapters 330 to achieve folding and storage. The first C-shaped frame 310 and the second C-shaped frame 320 each include a cross bar 311 and a pair of connecting rods 313 vertically connected to the two ends of the cross bar 311 through corner pieces 312, respectively. The first plug-in slot 301 is opened on the side of the corner piece 312 of the first C-shaped frame 310 away from the cross bar 311, and the second plug-in slot 302 is opened on the side of the corner piece 312 of the second C-shaped frame 320 away from the cross bar 311. Specifically, the corner pieces 312 of the first C-shaped frame 310 and the second C-shaped frame 320 together form the four corners of the top frame 300; the adapter 330 is an inverted isosceles trapezoidal structure (i.e., the upper base is at the bottom and the lower base is at the top), the connecting rod 313 of the first C-shaped frame 310 is hinged to the upper left end of the adapter 330 (i.e., one end of the lower base of the isosceles trapezoid), and the connecting rod 313 of the second C-shaped frame 320 is hinged to the upper right end of the adapter 330 (i.e., the other end of the lower base of the isosceles trapezoid); when folded, the first C-shaped frame 310 and the second C-shaped frame 320 are respectively folded downward around the hinge points of the connecting rod 313 and the adapter 330. The inverted setting of the adapter 330 of the isosceles trapezoidal structure can reduce the space occupied by the first C-shaped frame 310 and the second C-shaped frame 320 after being folded downward, thereby further reducing the volume of the camper after being stored.

[0064] See also Figure 3As shown, an expansion socket 303 is reserved at the top of the corner piece 312 for plugging in a C-shaped top rod 340; see Figure 4 As shown, the front and rear push rods 340 are arranged along the width direction of the top frame 300, and are used to install a ceiling (not shown in the figure) to transform the camping car into a stroller for infants and young children; the first plug connector 441 and the second plug connector 451 are respectively provided with a first avoidance notch 443 and a second avoidance notch 453, which are used to expose the expansion socket 303 to facilitate the insertion of the push rod 340.

[0065] See also Figure 1 and Figure 2 As shown, the folding mechanism 200 includes a first folding rod 210 and a second folding rod 220, both of which are C-shaped structures. The first folding rod 210 and the second folding rod 220 are connected by a pair of traction members 230 to achieve folding and storage; the two ends of the first folding rod 210 are respectively hingedly connected to the rear side of the front bridge 111 of the pair of front wheels 110, and the two ends of the second folding rod 220 are respectively hingedly connected to the front side of the rear bridge 121 of the pair of rear wheels 120; the two ends of the rear side of the front bridge 111 are respectively fixedly connected with the first support rod 112, the first support rod 112 extends obliquely upward, and its upper end is hinged to the lower left end of the adapter 330 (i.e., one end of the upper bottom of the isosceles trapezoid mentioned above), and the first support rod 112 is close to the left end of the adapter 330. A first curved plate 113 is hinged on the rod body near the adapter 330, the first curved plate 113 is bent toward the adapter 330, and its upper end is hinged to one end of the connecting rod 313 of the first C-shaped frame 310 close to the adapter 330; the second support rod 122 is fixedly connected to the two ends of the front side of the rear bridge 121, the second support rod 122 extends obliquely upward, and its upper end is hinged to the right end of the lower part of the adapter 330 (that is, the other end of the upper base of the above-mentioned isosceles trapezoid), and a second curved plate 123 is hinged on the rod body of the second support rod 122 close to the adapter 330, the second curved plate 123 is bent toward the adapter 330, and its upper end is hinged to one end of the connecting rod 313 of the second C-shaped frame 320 close to the adapter 330. When the camper is unfolded, the inclined first support rod 112 and the second support rod 122 form an eight-shaped support structure, and the first curved plate 113 and the second curved plate 123 stably support the first C-shaped frame 310 and the second C-shaped frame 320, thereby ensuring the stability of the top frame 300; when the camper is folded, the traction member 230 is lifted up, so that the side of the first folding rod 210 and the second folding rod 220 that is close to each other moves upward and the other side that is facing away from each other is folded downward, driving the front The bridge 111 and the rear bridge 121 move toward the middle, and drive the first C-shaped frame 310 and the second C-shaped frame 320 to fold downward through a quadrilateral structure composed of the connecting rod 313 of the first C-shaped frame 310 (and / or the connecting rod 313 of the second C-shaped frame 320), the adapter 330, the first support rod 112 (and / or the second support rod 122) and the first curved plate 113 (and / or the second curved plate 123), thereby retracting the front wheel 110 between the rear wheels 120 to achieve folding.
