Description

Technical Field

[0001] The utility model belongs to the technical field of camping vehicles, and particularly relates to a camping trolley. Background Art

[0002] A camping vehicle is a transportation tool designed specifically for outdoor activities, usually used to carry camping equipment such as tents, sleeping bags, cooking utensils and other necessities, facilitating campers to conduct long-term activities outdoors. A foldable camping vehicle is usually designed to be light, easy to carry and store, and can be quickly unfolded during camping to provide necessary space and functions.

[0003] However, the opening and closing processes of the folding frames of most camping vehicles are relatively complex, requiring multi-step operations, and cannot achieve quick folding and unfolding. Moreover, the complex folding frames will also increase the risk of failure, especially during frequent use or in harsh outdoor environments. Summary of the Utility Model

[0004] The utility model provides a camping trolley, aiming to solve the problem of the complex structure of the folding frame of camping vehicles in the prior art.

[0005] To solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0006] A camping trolley includes four corner seats and four columns, and the four columns are respectively arranged on the four corner seats; four foldable side frames are arranged between the four columns, wherein two side frames are parallel and opposite to each other, and the other two side frames are parallel and opposite to each other; each side frame includes two sliding ends and two connecting ends, a sliding seat is slidably arranged on each column, the two sliding ends of each side frame are respectively hinged to the corresponding adjacent two sliding seats, and the two connecting ends of each side frame are respectively rotatably connected to the corresponding adjacent two corner seats;

[0007] The side frame includes a folded state and an unfolded state. When the sliding seat is far away from the corner seat, the side frame is in the folded state, and when the sliding seat is close to the corner seat, the side frame is in the unfolded state.

[0008] Preferably, the side frame is a telescopic side frame, and the telescopic side frame is composed of a plurality of X-shaped side frames hinged end to end in sequence.

[0009] Preferably, the side frame includes a left side frame, a right side frame, a front side frame and a rear side frame. The left side frame and the right side frame are both composed of three X-shaped side frames hinged end to end in sequence, and the front side frame and the rear side frame are both composed of two X-shaped side frames hinged end to end in sequence.

[0010] Based on the above solution, the telescopic side frame can adjust its length according to requirements, which can maximize the space utilization efficiency and save space both during storage and transportation. Secondly, the X-shaped side frame has high structural stability, can provide strong support, and ensure the stability and safety of the camping vehicle during use.

[0011] In a preferred solution, both the left side frame and the right side frame include an upper left hinge end, a lower left hinge end, an upper right hinge end, and a lower right hinge end. The upper left hinge end and the upper right hinge end of the left side frame are respectively hinged to the sliding seats on the two left columns, and the lower left hinge end and the lower right hinge end of the left side frame are respectively hinged to the angle seats on the two left columns. The upper right hinge end and the upper right hinge end of the right side frame are respectively hinged to the sliding seats on the two right columns, and the lower right hinge end and the lower right hinge end of the right side frame are respectively hinged to the angle seats on the two right columns.

[0012] Both the front side frame and the rear side frame include a front upper hinge end, a front lower hinge end, a rear upper hinge end, and a rear lower hinge end. The front upper hinge end and the upper right hinge end of the front side frame are respectively hinged to the sliding seats on the two front columns, and the front lower hinge end and the lower right hinge end of the front side frame are respectively hinged to the angle seats on the two front columns. The rear upper hinge end and the upper right hinge end of the rear side frame are respectively hinged to the sliding seats on the two rear columns, and the rear lower hinge end and the lower right hinge end of the rear side frame are respectively hinged to the angle seats on the two rear columns.

[0013] Based on the above solution, the hinge design of the side frame enables the camping vehicle to be folded up when not in use, saving space and facilitating storage and transportation. In addition, by connecting the hinge ends to the sliding seats and angle seats of the columns, the side frame can provide additional support, increasing the structural stability of the entire camping vehicle and enabling it to withstand greater weights and different loads.

[0014] In a preferred solution, an armrest is provided on the front side of the front side frame.

[0015] Based on the above solution, when deploying or folding the camping vehicle, the user can apply force through the armrest to assist in completing the unfolding and folding actions of the side frame.

[0016] In a preferred solution, it further includes a bottom frame, and the bottom frame is in an X shape and is provided with a folding seat in the middle; when the folding seat is lifted, the bottom frame is folded up; when the folding seat is pressed down, the bottom frame is unfolded.

[0017] Based on the above solution, the X-shaped bottom frame can be quickly folded up by lifting or pressing down the folding seat when not in use, achieving rapid deployment, greatly reducing the occupied space, facilitating carrying and storage, and improving the use efficiency.

[0018] Preferably, the chassis includes four bottom bars, each of the four bottom bars includes a hinged end and a connecting end, the hinged ends of the four bottom bars are all hinged to the folding seat, and the connecting ends of the four bottom bars are respectively hinged to four corner seats; a limiting stop block for restricting the bottom bar to be horizontal when the folding seat is pressed down is provided on the folding seat.

[0019] Based on the above solution, the chassis is connected to the folding seat through the hinged ends of the bottom bars, so that the chassis can be conveniently folded and unfolded, facilitating the storage and transportation of the camping cart. In addition, the limiting stop block restricts the bottom bar to be in a horizontal position when the folding seat is pressed down, ensuring the stability of the chassis in the unfolded state, preventing the bottom bar from falling due to gravity, and at the same time ensuring the tightness of the chassis when folding.

[0020] Preferably, it further includes a limiting member for restricting the position of the sliding seat, and the limiting member is sleeved on the upper end of the column.

[0021] Based on the above solution, the limiting member prevents the sliding seat from moving excessively during unfolding or use by restricting the moving range of the sliding seat, so that the sliding seat will not exceed the predetermined range, preventing the side frame from separating from the column due to excessive movement of the sliding seat.

[0022] Preferably, it further includes four groups of wheel assemblies, and the four corner seats are respectively arranged on the four groups of wheel assemblies.

[0023] Preferably, the wheel assembly includes a wheel and a wheel seat, the wheel is rotatably arranged below the wheel seat, and the corner seat is arranged above the wheel seat.

[0024] Based on the above solution, the corner seat is located above the wheel seat, providing a stable support point for the vehicle, making the vehicle more stable when parked or in use.

[0025] The beneficial effects of the present utility model are as follows:

[0026] The present utility model provides a camping cart. Through the design of the corner seat and the sliding seat, the side frame can quickly switch between the folded state and the unfolded state according to the movement of the sliding seat. Since the side frame is connected into one body through four columns and four side frames, users only need to perform simple lifting or pressing actions to achieve the rapid unfolding and folding of the entire support frame, greatly reducing the operation complexity. At the same time, the simplified folding mechanism reduces potential failure points, making the camping cart more reliable under frequent use or harsh environments. Compared with the prior art, after the camping cart of the present utility model is folded, the height of the side frame will not exceed the height of the column, avoiding the problem of inconvenient carrying caused by the increase in the height of the side frame after folding in the traditional design. Therefore, the camping cart of the present utility model has a smaller volume after folding, facilitating carrying and storage. Description of the Drawings

Each group of wheel members 10 is composed of a wheel 10 and a wheel seat 11. The wheel 10 can rotate below the wheel seat 11, and the corner seat 1 is located above the wheel seat 11. The wheel 10 provides stable support and mobility at the bottom of the support frame, and at the same time, the combination of the wheel seat 11 and the corner seat 1 ensures the integrity and stability of the structure.

[0054] The following further explains and illustrates the present invention in combination with the working principle:

[0055] When unfolding, by moving the sliding seat 4 on the upright column 2, the sliding end of the side frame 3 slides downward along the sliding seat 4 on the upright column 2, approaching the corner seat 1. Or the user can lift the folding seat 7 in the middle of the chassis 6, making the sliding end of the side frame 3 slide downward along the sliding seat 4 on the upright column 2, approaching the corner seat 1, so that the X-shaped chassis 6 unfolds to form the side support of the vehicle; when folding, the user presses down the sliding seat, making the sliding end of the side frame 3 slide upward, away from the corner seat 1. Then the side frame 3 folds to the central position, and the chassis 6 is folded by pressing down the folding seat 7 to ensure that the chassis 6 fits closely, reducing the space occupied.

[0056] The present utility model is not limited to the above optional embodiments. On the premise of not conflicting with each other, various solutions can be arbitrarily combined; anyone can obtain other various forms of products under the inspiration of the present utility model.
