[0006] To overcome the shortcomings of existing technologies, this utility model provides a camping vehicle with a quick-release structure to solve technical problems such as inconvenient storage and troublesome wheel replacement.
[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows:
[0008] A campervan with a quick-release structure, including
[0009] The folding frame includes four uprights, a bottom folding assembly, two sets of first folding enclosure assemblies, and two sets of second folding enclosure assemblies mounted on the four uprights. The first folding enclosure assemblies, second folding enclosure assemblies, and bottom folding assemblies together form a box-type frame structure with an opening.
[0010] The cloth bag is equipped with multiple fasteners. Each of the uprights has a fastening seat that mates with the fasteners. The fasteners engage with their corresponding fastening seats.
[0011] The travel wheel assemblies are installed at the bottom of each of the columns. Each column has a locking structure at its bottom for detachable fixing of the travel wheel assemblies.
[0012] A lever assembly is mounted on one side of the folding frame. The user moves the campervan by applying pressure to the lever assembly.
[0013] Furthermore, the walking wheel assembly includes a wheel body, a mounting base, and a connector. The wheel body is rotatably connected to the bottom of the mounting base. The connector is fixed to the top of the mounting base and inserted into the bottom of the corresponding column.
[0014] The locking structure includes a locking element and a reset assembly. When the user applies pressure to the reset assembly, the locking element releases the locking of the connector. When the user removes the applied pressure, the locking element locks the connector.
[0015] Furthermore, the connector is divided into a guide portion, a locking portion, and a connecting portion from top to bottom. The outer force surface of the guide portion is provided with a guide slope that cooperates with the locking component; the diameter of the locking portion is smaller than the diameter of the bottom of the adjacent guide portion and the connecting portion, thereby forming a locking groove on the locking portion that cooperates with the locking component.
[0016] Furthermore, the locking element is slidably connected to the mounting bracket, and the sliding direction is perpendicular to the insertion direction of the connector. The locking element has a locking hole to lock the inserted connector.
[0017] Furthermore, the reset assembly includes a button and a reset spring. The button and reset spring are respectively located at both ends of the locking member. The column has a clearance through hole that mates with the button. In the initial state, the button protrudes to the outside from the clearance through hole.
[0018] Furthermore, the pull rod assembly includes a handle body, a mounting link, a connecting bracket, and two diagonal connecting rods. The inner ends of the two diagonal connecting rods are rotatably connected to the corresponding uprights, and the outer ends are rotatably connected to the connecting bracket. The handle body is detachably fixed to the connecting bracket via the mounting link.
[0019] Furthermore, the mounting rod is a hollow tube structure. The connecting bracket is provided with a plug-in portion that mates with the mounting rod. The inner end of the mounting rod is plugged into the connecting bracket.
[0020] Furthermore, a locking hole is provided at one end near the connecting bracket. A spring-loaded assembly is provided on the connecting bracket to mate with the locking hole. The spring-loaded assembly includes a ball and an elastic reset component. The ball can move inward or outward under the combined action of external force and the elastic reset component.
[0021] Furthermore, both the first folding enclosure assembly and the second folding enclosure assembly include multiple X-shaped cross-hinged rod groups connected end to end; the upper ends of both sides of the first folding enclosure assembly and the second folding enclosure assembly are hinged to the fastening seat, and the lower ends of both sides are respectively hinged to the corresponding hinged sleeve.
[0022] Furthermore, the bottom folding assembly includes a fixed base and multiple supporting rods. Each supporting rod is rotatably connected to the fixed base. The outer end of each supporting rod is rotatably connected to a corresponding column. When each supporting rod is extended outward, it forms an X-shaped structure.
[0023] Compared with the prior art, the present invention has the following advantages:
[0024] 1. This utility model provides a connector on the wheel body and a locking structure at the bottom of each column that cooperates with the connector to lock or unlock the connector. This facilitates the replacement of the wheel body in the camping vehicle while reducing the space occupied by the camping vehicle frame when folded.
[0025] 2. This utility model divides the connector into a guide part, a locking part, and a connecting part. A guide slope that cooperates with the locking part is provided on the outer surface of the guide part. This allows the locking part to automatically slide inward under the push of the guide slope as it extends into the locking hole. When the locking part is aligned with the locking part, it can be inserted into the locking groove of the locking part under the push of the return spring, thereby achieving automatic locking between the connector and the locking part.

Therefore, they should not be construed as limitations on this utility model.
[0037] The present invention will be further described below with reference to the accompanying drawings.
[0038] like Figure 1 and 2 As shown, a campervan with a quick-release structure includes a folding frame 1, a cloth bag 2, a pull rod assembly 3, and multiple wheel assemblies 4. The folding frame 1 includes four uprights 1-1, a bottom folding assembly 1-2, two sets of first folding enclosure assemblies 1-3, and two sets of second folding enclosure assemblies 1-4. The four uprights 1-1 are spaced apart at the corners of the same rectangle. Each wheel assembly 4 is detachably fixed to the bottom of its corresponding upright 1-1.
[0039] The bottom folding assembly 1-2 is mounted on four uprights 1-1 and rotatably connected to each upright 1-1. Two sets of first folding enclosure assemblies 1-3 are spaced apart relative to each other along the width of the rectangle and connected to their respective uprights 1-1. Two sets of second folding enclosure assemblies 1-4 are spaced apart relative to each other along the length of the rectangle and connected to their respective uprights 1-1. The first folding enclosure assemblies 1-3, second folding enclosure assemblies 1-4, and bottom folding assembly 1-2 together form an open box-shaped vehicle frame structure. A cloth bag 2 is disposed within the formed box-shaped vehicle frame structure for storing the goods to be transported. A pull rod assembly 3 is mounted on one side of one of the second folding enclosure assemblies 1-4. The user moves the campervan by applying pressure to the pull rod assembly 3.
[0040] like Figure 1 Therefore, fasteners 5 are fixed at the four corners of the top of the cloth bag 2. Each upright 1-1 has a fastening seat 6 at its top that mates with the fasteners 5. Through the insertion and engagement between the fasteners 5 and the fastening seats 6, the cloth bag 2 can be quickly installed when the folding frame 1 is unfolded and quickly disassembled when the folding frame 1 is folded up.
[0041] In practical use, pressing down the bottom folding assembly 1-2 unfolds the campervan, forming a box-like structure. The cloth bag 2 is fitted inside the box structure, and the four corners at the top are secured to the corresponding uprights 1-1 via fasteners 5, allowing it to store transported goods. After use, the cloth bag 2 can be separated from the box structure by removing the fasteners 6 from each upright 1-1. Lifting the bottom folding assembly 1-2 causes the first folding enclosure assembly 1-3 and the second folding enclosure assembly 1-4 to fold towards the center, forming a bundle for easy storage and carrying.
[0042] like Figure 2 and 9 As shown, both the first and second folding fencing assemblies include multiple X-shaped cross-hinged rod groups connected end-to-end. Each column has a hinged sleeve fixed to its center, which mates with the X-shaped cross-hinged rod group. Specifically, the lower ends of the X-shaped cross-hinged rod groups located on both sides of the first and second folding fencing assemblies are hinged to their corresponding hinged sleeves; the upper ends are hinged to their corresponding fasteners 6.
[0043] In this embodiment, there are three folding rod groups in the first folding enclosure assembly 1-3 and two folding rod groups in the second folding enclosure assembly 1-4.
[0044] like Figure 3As shown, the bottom folding assembly 1-2 includes a fixed base 1-2-1 and multiple supporting rods 1-2-2. Each supporting rod 1-2-2 is rotatably connected to the fixed base 1-2-1. When each supporting rod 1-2-2 is extended outward, it forms an X-shaped structure. The bottom of each column 1-1 is provided with a connector that mates with each supporting rod 1-2-2. The outer end of each supporting rod 1-2-2 is rotatably connected to its respective connector.
[0045] When the campervan needs to be deployed, pressing down the fixed base 1-2-1 causes the supporting rods to extend outwards, simultaneously pushing the uprights 1-1 outwards. With the cooperation of the first folding enclosure assembly 1-3 and the second folding enclosure assembly 1-4, an open box structure is formed. When the campervan needs to be folded up, lifting the fixed base 1-2-1 causes the supporting rods 1-2-2 to retract inwards, which in turn causes the uprights 1-1 to retract inwards, facilitating storage for the user.
[0046] like Figure 2 and 4 As shown, the walking wheel assembly 4 includes a wheel body 4-1, a mounting base 4-2, and a connector 4-3. The wheel body 4-1 is rotatably connected to the bottom of the mounting base 4-2. The connector 4-3 is fixed to the top of the mounting base 4-2 for connection and fixation with the column 1-1.
[0047] A mounting bracket is provided on the column 1-1, and a locking structure 7 is provided on its top to cooperate with the connector 4-3. The locking structure 7 includes a locking element 7-1 and a reset assembly. When the connector 4-3 is inserted into the mounting bracket, it can be quickly locked by the locking element 7-1. When the user applies pressure to the reset assembly, the locking element 7-1 is unlocked, allowing the connector 4-3 to be easily disengaged, facilitating the removal of the wheel body 4-1.
[0048] The specific structure is as follows: Figure 5 , 6 As shown in Figure 7, the locking element 7-1 is slidably connected to the mounting bracket, and the sliding direction is perpendicular to the insertion direction of the connector 4-3. The locking element 7-1 has a locking hole for locking the inserted connector 4-3. The reset assembly includes a button 7-2 and a reset spring 7-3. The button 7-2 and the reset spring 7-3 are respectively located at both ends of the locking element 7-1. The column 1-1 has a clearance through hole that mates with the button 7-2. In the initial state, the button 7-2 protrudes from the clearance through hole. The outer end of the reset spring 7-3 abuts against the inner wall of the mounting bracket.
[0049] During use, when the user applies pressure to button 7-2, it will cause locking member 7-1 to slide inward, and return spring 7-3 will deform. Locking member 7-1 slides inward to its end, and the locking hole on locking member 7-1 is aligned with the plug 4-3, so that plug 4-3 can be smoothly disengaged from the locking hole.
[0050] The connector 4-3 is divided into a guide portion 4-3-1, a locking portion 4-3-2, and a connecting portion 4-3-3 from top to bottom. The diameter of the locking portion 4-3-2 is smaller than the diameter of the bottom of the adjacent guide portion 4-3-1 and the connecting portion 4-3-3, thereby forming a locking groove on the locking portion 4-3-2 that mates with the locking member 7-1.
[0051] When the locking member 7-1 slides inward and the locking hole on the locking member 7-1 aligns with the connector 4-3, the connector 4-3 can be smoothly inserted into the locking hole. When the connector 4-3 slides until the locking part 4-3-2 is flush with the locking member 7-1, the locking member 7-1 resets, causing it to embed into the locking groove, thus locking the connector 4-3 in the vertical direction.
[0052] Furthermore, the outer surface of the guide part 4-3-1 is provided with a guide slope that mates with the locking hole of the locking member 7-1. When the guide slope extends into the locking hole, the locking member 7-1 will automatically slide inward under the push of the guide slope, thereby realizing automatic locking between the plug-in part 4-3 and the locking member 7-1.
[0053] like Figure 8 As shown, the pull rod assembly 3 includes a handle body, a mounting link 3-1, a connecting bracket 3-2, and two diagonal connecting rods 3-3. The inner ends of both diagonal connecting rods 3-3 are rotatably connected to the connectors on the corresponding uprights 1-1, and their outer ends are rotatably connected to the connecting brackets 3-2. The handle body is detachably fixed to the connecting brackets 3-2 via the mounting link 3-1. Users can assemble and disassemble the handle body according to their needs.
[0054] In this embodiment, the mounting rod 3-1 is a hollow tube structure. The connecting bracket 3-2 is provided with a plug-in part that mates with the mounting rod 3-1. The inner end of the mounting rod 3-1 is plugged into the connecting bracket 3-2 to fix the mounting rod 3-1 and the connecting bracket 3-2.
[0055] Furthermore, a locking hole is provided at one end of the mounting rod 3-1 near the connecting bracket 3-2. A spring-loaded assembly that mates with the locking hole is provided on the insertion part of the connecting bracket 3-2. The spring-loaded assembly includes a ball 3-4 and a spring-loaded reset member 3-5. The insertion part has a mounting hole that mates with the ball 3-4. The ball 3-4 is disposed within the mounting hole and can move inward or outward under the combined action of external force and the spring-loaded reset member 3-5.
[0056] In use, when the mounting rod 3-1 is inserted into the connector, it pushes the ball 3-4 into the mounting hole, causing the elastic reset member 3-5 to deform. When the locking hole on the mounting rod 3-1 aligns with the position of the ball 3-4, the elastic reset member 3-5 pushes the ball 3-4 back into place, allowing it to extend into the locking hole and lock the position of the mounting rod 3-1. When the user needs to disassemble the support rod, pressure is applied to the ball 3-4 to retract it inward and disengage it from the locking hole. The user can then disassemble the mounting rod 3-1 by pulling it outward.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
