Description

Technical Field

[0001] This utility model belongs to the field of camping vehicle technology, specifically relating to a foldable camping vehicle. Background Technology

[0002] A foldable camping vehicle is a powerful tool for outdoor camping, primarily used for easily transporting heavy equipment such as tents, sleeping bags, tables, chairs, and cooking utensils, freeing up your hands. It's especially suitable for long-distance transport from parking lots to campsites, and its wide tires easily handle complex terrains such as beaches, grasslands, and gravel. When folded, its compact size makes it easy to store in a car trunk or a corner of your home.

[0003] However, most products currently have obvious shortcomings: the folding structure is complex, the operation takes a long time, and frequent folding can easily lead to damage or detachment of parts. Utility Model Content

[0004] This invention provides a foldable camping vehicle, which aims to solve the problem that existing foldable camping vehicles have complex structures and large volumes after folding.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a foldable camping vehicle, including a folding assembly. The folding assembly includes a first telescopic rod and a second telescopic rod, which are connected by a connecting seat. The first telescopic rod includes a first outer rod and a first inner rod. The first telescopic rod has a folded state and an unfolded state. When the first telescopic rod is in the unfolded state, the axis of the first inner rod intersects the axis of the first outer rod, and one end of the first inner rod abuts against the connecting seat. When the first telescopic rod is in the folded state, the axes of the first inner rod and the first outer rod are parallel, and the first inner rod is inserted into the first outer rod.

[0007] The second telescopic rod includes a second outer rod and a second inner rod. The second telescopic rod has a folded state and an unfolded state. When the second telescopic rod is in the unfolded state, the axis of the second inner rod intersects with the axis of the second outer rod, and the two ends of the second inner rod abut against the connecting seat. When the second telescopic rod is in the folded state, the axis of the second inner rod is parallel to the axis of the second outer rod, and the second inner rod is inserted into the second outer rod.

[0008] The folding assembly includes a folded state and an unfolded state. When the folding assembly is in the folded state, both the first telescopic rod and the second telescopic rod are folded, and the axis of the first outer rod is parallel to the axis of the second outer rod. When the folding assembly is in the unfolded state, both the first telescopic rod and the second telescopic rod are unfolded, and the first telescopic rod and the second telescopic rod are in an X-shape.

[0009] In a preferred embodiment, the connecting seat is provided with a first insertion tube for inserting the first inner rod and a second insertion tube for inserting the second inner rod, and the connecting seat further includes a first limiting part for limiting the first inner rod and a second limiting part for limiting the second inner rod;

[0010] When the first telescopic rod is in the extended state, the first inner rod is inserted into the first insertion tube and abuts against the first limiting part, and the second inner rod is inserted into the second insertion tube and abuts against the second limiting part;

[0011] When the second telescopic rod is in the folded state, the first limiting part releases its restriction on the first inner rod, and the first inner rod passes through the first insertion tube and is inserted into the first outer rod; the second limiting part releases its restriction on the second inner rod, and the second inner rod passes through the second insertion tube and is inserted into the second outer rod.

[0012] Based on the above scheme, after the first inner rod and the second inner rod are inserted into the corresponding insertion tube, their ends press against the limiting part to form a three-point force structure: insertion tube wall + limiting surface + outer rod interface, which reduces the stress at the hinge point and improves the torsional stiffness. The limiting part physically blocks the displacement of the inner rod, avoiding the swaying problem of the traditional pure hinge structure.

[0013] In a preferred embodiment, both the first insertion tube and the second insertion tube are fixed to the connecting seat; both the first outer rod and the second outer rod are fixed to the connecting seat.

[0014] Based on the above solution, traditional structures require additional bolts to fix each member. This solution uses an integrated connector to reduce the number of fasteners, reducing weight while avoiding the risk of screws loosening. Moreover, there is no relative movement between the connector and the outer rod, reducing folding failures.

[0015] In a preferred embodiment, the first limiting part is a first limiting plate disposed on the connecting seat, and the second limiting part is a second limiting plate disposed on the connecting seat, wherein the first limiting plate and the second limiting plate are rotatably connected.

[0016] Based on the above solution, when the inner rod needs to slide into the outer rod for folding, the limiting plate rotates to avoid it, eliminating the restriction on the linear movement path of the rod. Traditional fixed limiting plates will collide with the end of the inner rod, causing folding to jam. This solution eliminates the need for manual adjustment of the limiting plate during folding, completing the storage in one step. When the inner rod is pulled out to the unfolded position, the limiting plate automatically rotates back, precisely abutting against the end face of the inner rod, thereby restricting the movement of the inner rod.

[0017] In a preferred embodiment, the connecting seat includes a first part and a second part, with the first telescopic rod and the second telescopic rod located between the first part and the second part, and the first part and the second part being rotatably connected.

[0018] In a preferred embodiment, the first outer rod is fixed to the first part, and the second outer rod is fixed to the second part.

[0019] Based on the above solution, when the first part and the second part rotate, they drive the outer rod to rotate together, thereby achieving folding. The campervan can be folded simply by moving any one of the outer rods, which is simple, convenient, and not prone to malfunction.

[0020] In a preferred embodiment, the first part and the second part are connected by a connecting shaft, the first limiting plate and the second limiting plate are connected by a connecting shaft, and the connecting shaft connecting the first part and the second part is the same shaft as the connecting shaft connecting the first limiting plate and the second limiting plate; the end of the first limiting plate away from the connecting shaft is fixed to the second part of the connecting seat by bolts, and the end of the second limiting plate away from the connecting shaft is fixed to the first part of the connecting seat by bolts.

[0021] Based on the above solution, the limiting part and the connecting seat are coaxial, which can realize that the first telescopic rod and the second telescopic rod rotate synchronously when folding, and the limiting plate can limit the inner rod in time when unfolding and release the limit on the inner rod in time when unfolding, so as to realize synchronous rotation. Moreover, coaxiality can reduce the probability of failure.

[0022] In a preferred embodiment, the first part is provided with a first arc-shaped portion for fixing the first outer rod and a second arc-shaped portion for fixing the second insertion tube, and the second part is provided with a third arc-shaped portion for fixing the second outer rod and a fourth arc-shaped portion for fixing the first insertion tube.

[0023] Based on the above solution, the arc-shaped part can increase the area of ​​wrapping and fixing the outer rod and fit the outer surface of the outer rod, thereby achieving the effect of enhancing stability.

[0024] In a preferred embodiment, the folding assembly comprises two sets, namely a left folding assembly and a right folding assembly. The first telescopic rod of the left folding assembly is connected to the first telescopic rod of the right folding assembly via a crossbar, and the second telescopic rod of the left folding assembly is connected to the second telescopic rod of the right folding assembly via a crossbar.

[0025] In a preferred embodiment, the upper end of the first inner rod constituting the left folding assembly is connected to the upper end of the first inner rod constituting the right folding assembly via a first crossbar, and the lower end of the first outer rod constituting the left folding assembly is connected to the lower end of the first outer rod constituting the right folding assembly via a second crossbar.

[0026] The upper end of the second inner rod that makes up the left folding assembly is connected to the upper end of the second inner rod that makes up the right folding assembly via a third crossbar, and the lower end of the second outer rod that makes up the left folding assembly is connected to the lower end of the second outer rod that makes up the right folding assembly via a fourth crossbar.

[0027] Based on the above solution, the left and right folding components are connected by a crossbar to form a more stable frame structure, which can effectively disperse and bear external forces, improve the stability of the campervan during use, and reduce accidental folding caused by accidental collisions or external forces.

[0028] The beneficial effects of this utility model are as follows:

[0029] This invention provides a foldable camping vehicle. Traditional camping vehicles typically require a separate, relatively complex rectangular or frame-type chassis to support the vehicle body and connect the wheels. In this invention, the X-shaped folding assembly directly supports the vehicle body and connects the wheels. In the unfolded state, the inner rod directly rests against the connecting seat, and the load is directly transferred to the telescopic rod through the connecting seat, and then to the wheels. This allows the foldable camping vehicle, even without a chassis, to provide good support, ensuring the stability and load-bearing capacity of the camping vehicle in the unfolded state. In the folded state, the first and second inner rods are inserted into their respective outer rods, bringing the telescopic rods to their shortest possible position. The two folded outer rods, along with their inner rods, are arranged parallel to each other, forming a narrow, long, and compact strip structure after folding. This eliminates the need for an additional frame for storage, significantly simplifying the overall structure and reducing the overall weight, making it easier to carry and fit into narrow spaces such as car trunks and storage cabinets. In addition, the assembly process of the foldable camping vehicle provided by this utility model is simpler, mainly focusing on the connection between the folding components and the wheels, without the need to assemble the base frame and install other parts.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0039] See Figures 1-5This embodiment provides a foldable camping vehicle, including a folding assembly. The folding assembly includes a first telescopic rod 1 and a second telescopic rod 2. The first telescopic rod 1 and the second telescopic rod 2 are connected by a connecting seat 3. The first telescopic rod 1 includes a first outer rod 12 and a first inner rod 11. The first telescopic rod 1 has a folded state and an unfolded state. When the first telescopic rod 1 is in the unfolded state, the axis of the first inner rod 11 intersects the axis of the first outer rod 12, and one end of the first inner rod 11 abuts against the connecting seat 3. When the first telescopic rod 1 is in the folded state, the axis of the first inner rod 11 is parallel to the axis of the first outer rod 12, and the first inner rod 11 is inserted into the first outer rod 12.

[0040] The second telescopic rod 2 includes a second outer rod 22 and a second inner rod 21. The second telescopic rod 2 has a folded state and an unfolded state. When the second telescopic rod 2 is in the unfolded state, the axis of the second inner rod 21 intersects the axis of the second outer rod 22, and the two ends of the second inner rod 21 abut against the connecting seat 3. When the second telescopic rod 2 is in the folded state, the axis of the second inner rod 21 is parallel to the axis of the second outer rod 22, and the second inner rod 21 is inserted into the second outer rod 22.

[0041] The folding assembly includes a folded state and an unfolded state. When the folding assembly is in the folded state, both the first telescopic rod 1 and the second telescopic rod 2 are folded, and the axis of the first outer rod 12 is parallel to the axis of the second outer rod 22. When the folding assembly is in the unfolded state, both the first telescopic rod 1 and the second telescopic rod 2 are unfolded, and the first telescopic rod 1 and the second telescopic rod 2 are X-shaped.

[0042] The connecting seat 3 is provided with a first insertion tube 4 for inserting the first inner rod 11 and a second insertion tube 5 for inserting the second inner rod 21. The connecting seat 3 also includes a first limiting part 6 for limiting the first inner rod 11 and a second limiting part 7 for limiting the second inner rod 21.

[0043] When the first telescopic rod 1 is in the extended state, the first inner rod 11 is inserted into the first insertion tube 4 and abuts against the first limiting part 6, and the second inner rod 21 is inserted into the second insertion tube 5 and abuts against the second limiting part 7.

[0044] When the second telescopic rod 2 is in the folded state, the first limiting part 6 releases the restriction on the first inner rod 11, and the first inner rod 11 passes through the first insertion tube 4 and is inserted into the first outer rod 12; the second limiting part 7 releases the restriction on the second inner rod 21, and the second inner rod 21 passes through the second insertion tube 5 and is inserted into the second outer rod 22.

[0045] Specifically, when both the first telescopic rod 1 and the second telescopic rod 2 are in the extended state, the first inner rod 11 is inserted into the first insertion tube 4 and abuts against the first limiting part 6, while the second inner rod 21 is inserted into the second insertion tube 5 and abuts against the second limiting part 7. At this time, the limiting part provides a stop to ensure stable support for the inner rods at the extended angle. When folding is required, the first limiting part 6 releases the limiting constraint on the first inner rod 11, allowing the first inner rod 11 to move along the axial direction, so that it passes through the first insertion tube 4 and is finally fully inserted into the first outer rod 12; similarly, the second limiting part 7 releases the limiting constraint on the second inner rod 21, allowing the second inner rod 21 to pass through the second insertion tube 5 and be fully inserted into the second outer rod 22, thereby achieving the compact state of the entire telescopic rod retraction and folding assembly.

[0046] Additionally, see Figure 1-3 The first insertion tube 4 and the second insertion tube 5 are both fixed to the connecting seat 3; the first outer rod 12 and the second outer rod 22 are both fixed to the connecting seat 3.

[0047] The first limiting part 6 is a first limiting plate disposed on the connecting seat 3, and the second limiting part 7 is a second limiting plate disposed on the connecting seat 3. The first limiting plate and the second limiting plate are rotatably connected.

[0048] The connecting seat 3 includes a first part 31 and a second part 32. The first telescopic rod 1 and the second telescopic rod 2 are located between the first part 31 and the second part 32, and the first part 31 and the second part 32 are rotatably connected.

[0049] The first outer rod 12 is fixed to the first part 31, and the second outer rod 22 is fixed to the second part 32.

[0050] Furthermore, the first part 31 and the second part 32 are connected by a connecting shaft 8, and the first limiting plate and the second limiting plate are connected by a connecting shaft 8. The connecting shaft 8 connecting the first part 31 and the second part 32 is the same shaft as the connecting shaft 8 connecting the first limiting plate and the second limiting plate. The end of the first limiting plate away from the connecting shaft 8 is fixed to the second part 32 of the connecting seat 3 by bolts, and the end of the second limiting plate away from the connecting shaft 8 is fixed to the first part 31 of the connecting seat 3 by bolts.

[0051] Specifically, when the folding assembly is unfolded, the first inner rod 11 is inserted into and fixed in the first insertion tube 4, with its end abutting against the first limiting plate. Simultaneously, the second inner rod 21 is inserted into and fixed in the second insertion tube 5, with its end abutting against the second limiting plate. At this time, the first and second limiting plates are in a locked position, working together with the connecting seat 3 to constrain the movement of the inner rods, keeping the telescopic rods unfolded and forming a stable X-shaped structure. When folding is required, rotating the first part 31 and the second part 32 of the connecting seat 3 causes the first and second limiting plates, being coaxial, to simultaneously release their abutment on the inner rods, causing the first outer rod 12 and the second outer rod 22 fixed thereon to move closer together. Simultaneously, the first inner rod 11 passes through the first insertion tube 4 and inserts into the first outer rod 12, and the second inner rod 21 passes through the second insertion tube 5 and inserts into the second outer rod. Finally, both telescopic rods are fully retracted and their axes are parallel, achieving overall folding. During this process, the split rotation of the connecting seat 3 directly drives the change in the position of the outer rods, combined with the unlocking of the limiting plates and the synchronous sliding and retraction of the inner rods.

[0052] In order to fix the outer rod with the connecting part, based on any of the above solutions, the first part 31 is provided with a first arc-shaped part 9 for fixing the first outer rod 12 and a second arc-shaped part 10 for fixing the second insertion tube 5, and the second part 32 is provided with a third arc-shaped part for fixing the second outer rod 22 and a fourth arc-shaped part for fixing the first insertion tube 4.

[0053] Specifically, the first part 31 of the connecting seat 3 fixes the first outer rod 12 through its first arc-shaped portion 9, and fixes the second insertion tube 5 through its second arc-shaped portion 10; while the second part 32 fixes the second outer rod 22 through its third arc-shaped portion, and fixes the first insertion tube 4 through its fourth arc-shaped portion. The first part 31 and the second part 32 of the connecting seat 3 rotate relative to each other. The first arc-shaped portion 9 drives the first outer rod 12 and the second arc-shaped portion 10 drives the second insertion tube 5 to rotate synchronously, while the fourth arc-shaped portion drives the first insertion tube 4 and the third arc-shaped portion drives the second outer rod 22 to move in opposite directions, so that the two sets of telescopic rods come closer to each other; finally, a compact folded state is achieved in which the outer rod and inner rod are fully retracted and arranged in parallel.

[0054] The folding assembly includes two sets, namely a left folding assembly and a right folding assembly. The first telescopic rod 1 of the left folding assembly and the first telescopic rod 1 of the right folding assembly are connected by a crossbar, and the second telescopic rod 2 of the left folding assembly and the second telescopic rod 2 of the right folding assembly are connected by a crossbar.

[0055] The upper end of the first inner rod 11 that forms the left folding assembly is connected to the upper end of the first inner rod 11 that forms the right folding assembly through a first crossbar 11, and the lower end of the first outer rod 12 that forms the left folding assembly is connected to the lower end of the first outer rod 12 that forms the right folding assembly through a second crossbar 12.

[0056] The upper end of the second inner rod 21 that forms the left folding assembly is connected to the upper end of the second inner rod 21 that forms the right folding assembly via a third crossbar 13, and the lower end of the second outer rod 22 that forms the left folding assembly is connected to the lower end of the second outer rod 22 that forms the right folding assembly via a fourth crossbar 14.

[0057] Specifically, referring to Figure 4, the upper ends of all inner rods and the lower ends of all outer rods are fastened to the corresponding crossbars with U-shaped clamps and bolts, forming a rigid frame. In the unfolded state, the two sets of X-shaped folding components open synchronously. The first crossbar 11 and the third crossbar 13 form the upper support surface, and the second crossbar 12 and the fourth crossbar 14 form the lower support surface. At this time, a cloth bag can be placed on the frame to form a carrying platform. The load is transferred to the crossbars through the cloth bag, and then distributed to each telescopic rod through the U-shaped clamps. Finally, it is transmitted to the wheels by the rigid structure composed of the welded and fixed outer rod, the insertion pipe, and the connecting seat 3. When folding, the constraint of the limiting plate is released synchronously, and the first and second parts 32 of the connecting seat 3 are rotated to drive the two sets of telescopic rods to retract synchronously: each inner rod passes through the insertion pipe and retracts into the coaxial outer rod. At the same time, the first crossbar 11 and the third crossbar 13 move down with the retraction of the inner rod, and the second crossbar 12 and the fourth crossbar 14 move closer with the rotation of the outer rod. Finally, all the crossbars and the retracted telescopic rods are stacked in parallel to form a compact strip structure, realizing the overall folding.

[0058] In addition, four wheels are provided below the second crossbar 12 and the fourth crossbar 14. The four wheels are evenly distributed at the four ends of the second crossbar 12 and the fourth crossbar 14. The second outer rod 22 of the left folding assembly and the right folding assembly are also connected to a handle assembly for pushing the campervan.

[0059] The following explanation, based on the working principle, further illustrates this utility model:

[0060] When unfolded for use, the two sets of symmetrical X-shaped folding components are fixed and unfolded through the first part 31 and the second part 32 of the connecting seat 3. At this time, the first limiting plate and the second limiting plate lock the first inner rod 11 and the second inner rod 21 to the corresponding limiting plates respectively. At the same time, the first inner rod 11 is inserted into the first insertion tube 4, and the second inner rod 21 is inserted into the second insertion tube 5. The first crossbar 11 is simultaneously fixed to the upper end of the left and right first inner rods 11, and the third crossbar 13 is fixed to the upper end of the left and right second inner rods 21, forming an upper support surface. The second crossbar 12 is connected to the lower end of the left and right first outer rods 12, and the fourth crossbar 14 is connected to the lower end of the left and right second outer rods 22, forming a lower support surface, forming a carrying frame that can be fitted with a cloth bag. The load is transmitted to the crossbar frame through the cloth bag, and the force is transmitted to the connecting seat 3 through the inner rod. Finally, it is transmitted to the wheel by the welded and fixed outer rod and insertion tube. At this time, the X-shaped structure and the welded joint form a stable load-bearing system.

[0061] When folding and storing, first rotate to release the constraint of the limiting plate on the inner rod, then rotate the first part 31 and the second part 32 of the connecting seat 3 relative to each other, driving the first outer rod 12 and the second insertion tube 5 welded to the first part 31, and the right second outer rod 22 and the left first insertion tube 4 welded to the second part 32 to move synchronously, so that the two sets of folding components are gathered towards the center line; during this process, the first inner rod 11 passes through the first insertion tube 4 and retracts into the coaxial first outer rod 12, the second inner rod 21 passes through the second insertion tube 5 and retracts into the second outer rod 22, at the same time the first crossbar 11 and the third crossbar 13 move down with the inner rod as it retracts, and the second crossbar 12 and the fourth crossbar 14 gather with the outer rod as it rotates, and finally all the telescopic rods are completely stored and the four crossbars are stacked in parallel into a compact single-layer structure, realizing overall folding.

[0062] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
