Traditional camping crates typically employ a rigid box and lid structure, offering limited functionality and primarily serving as storage for items. This fails to meet users' needs for versatility and flexibility during outdoor activities.

[0003] More importantly, in existing camping crates, the side panels have fixed functions, serving only to enclose space. The entire structure and function of the product are fixed at the factory, and users cannot customize the structure to their own needs. This rigid design makes camping crates unsuitable for diverse usage scenarios. For example, when a desktop, shelf, or other functions are needed, users often need to carry additional equipment, which not only increases the burden of carrying but also reduces the convenience of the camping experience.

[0004] Therefore, there is an urgent need in this field for an innovative camping crate solution that can fundamentally solve the above problems, enabling the reuse of component functions and flexible adjustment of structural dimensions, thereby greatly improving the adaptability and practicality of the product without excessively increasing cost and weight. Existing technologies urgently need improvement to address these issues. Summary of the Invention

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Outdoor camping is becoming increasingly popular, and camping crates, as essential tools for storing and carrying equipment, directly impact user experience through their functionality and convenience. Traditional camping crates typically consist of a rigid body and lid, offering limited functionality solely for storage. More importantly, the side panels of existing camping crates are rigid, merely serving to enclose space; the entire product's structure is fixed at the factory, preventing users from customizing the structure to their needs. Therefore, there is an urgent need for an innovative camping crate solution that fundamentally addresses these issues, enabling component reuse and flexible dimensional adjustments, thereby significantly improving product adaptability and practicality without excessively increasing cost and weight.

[0023] For example, suppose a camping enthusiast finds that their traditional camping crate can only store items and cannot provide a convenient platform for eating or other activities. When they need to prepare food or engage in other activities, they have to take their belongings out of the crate and find or set up an additional table. This not only increases the burden of carrying items but also reduces the convenience of camping. If these problems are not addressed, the limited functionality of camping crates will severely restrict their application in outdoor activities, significantly diminishing the user experience and potentially leading to users abandoning their use altogether due to inconvenience.

[0024] In this regard, such as Figures 1 to 6 The camping box shown has a load-bearing base, which is configured as the main support structure of the camping box; The plate-shaped assembly consists of two detachable plate-shaped assemblies mounted on opposite sides of a support base. The plate-shaped assemblies are configured to perform at least two different structural functions on the camping box by changing their mounting positions on the support base. An adjustment unit, located on the side wall of the supporting substrate, is used to determine the size of the plate-shaped assembly.

[0025] Specifically, the support base can take various structural forms, such as being made of metal profiles, composite materials, or high-strength plastics, to ensure that it has sufficient strength and stability to support the entire structure of the camping box and its internal items. The design of the support base can be an open frame structure or a semi-enclosed structure with partial enclosure, depending on the specific purpose of the camping box and the required load-bearing capacity. As a preferred implementation, the support base can be designed as a modular frame, which is convenient for users to assemble and disassemble according to their needs.

[0026] The panel components are the core of this camping crate's versatility. Two panel components are detachably mounted on either side of the support base. These components can be made of lightweight, high-strength materials such as aluminum alloy, carbon fiber composites, or high-density polyethylene sheets. Crucially, by changing their mounting position on the support base, the panel components can achieve at least two different structural functions. For example, when mounted on the side of the support base, they serve as side walls, protecting and enclosing the contents of the camping crate. When these panel components are detached and horizontally reinstalled on one side of the support base, or unfolded using specific connection methods, they can transform into a tabletop, shelf, or work surface. This design allows the camping crate to flexibly switch functions according to changing usage scenarios without adding extra components, greatly enhancing the product's practicality.

[0027] The adjustment unit is set on the side wall of the support base. Its main function is to determine the size of the plate assembly. The plate assembly of suitable size can be designed according to the installation position of the adjustment unit to adapt to different functional requirements or space constraints.

[0028] When designing this camping crate, the installation positions of the units can be adjusted to determine the appropriate size of the plate-like components. When using this camping crate, users can flexibly adjust its functions according to different camping scenarios and needs. For example, during transportation and storage, two plate-like components can serve as side walls supporting the base, forming a compact crate that effectively protects the contents. Upon arrival at the campsite, if a work surface is needed for preparing food or storing items, users can easily detach one or two plate-like components from the side walls, unfolding them into a stable tabletop. This flexible functional switching transforms the camping crate from merely a storage tool into a multifunctional piece of equipment integrating storage, operation, and leisure, greatly enhancing the convenience and comfort of outdoor activities.

[0029] As one embodiment of this utility model, the supporting base is composed of multiple rods with square cross-sections; The adjustment unit is a rod with a square cross-section. The adjustment unit is set vertically, and both the upper and lower ends of the adjustment unit are fixedly connected to the rod of the supporting base. Both the support base rod and the adjustment unit rod are equipped with positioning units, each including a positioning groove 1 formed on the rod.

[0030] The load-bearing base consists of multiple square-cross-section rods. This means the main support structure is no longer a single, monolithic structure, but rather composed of interconnected rods with square cross-sections. These rods can be made of metal, high-strength plastic, or other composite materials. Their square cross-sections provide uniform bending and torsional resistance in multiple directions, thus enhancing the overall structural rigidity and stability. The adjustment unit is also a square-cross-section rod, vertically positioned, with its upper and lower ends fixedly connected to the load-bearing base rods. This means the adjustment unit itself adopts a similar structural form to the load-bearing base rods. Its vertical positioning and secure connection to the load-bearing base further enhance the camping box's lateral support and overall frame stability. The positioning unit includes positioning slots 1 formed on the rods. These slots, pre-machined on both the load-bearing base rods and the adjustment unit rods, are used for positioning and connecting other components. These positioning slots 1 can be through-hole or blind-slot designs, with their dimensions and positions precisely calculated to ensure the accuracy and strength of connections with plate-like components or other accessories. This standardized connection method not only simplifies the assembly and disassembly process of the camping box, but also ensures a tight fit between the components, further enhancing the overall integrity and stability of the structure.

[0031] As one embodiment of this utility model, the supporting base also includes a bottom plate and two enclosure plates 2. The bottom plate and the two enclosure plates 2 are formed by opening slots around their perimeter to form a first protruding plate. The first protruding plate is inserted into the positioning slot 1 on the supporting base rod.

[0032] The introduction of the base plate and the enclosure plate 2 is intended to provide the camping box with solid bottom support and lateral enclosure, thereby forming a relatively enclosed storage space. The first protruding plate refers to a protruding structure integrally formed or formed by other connection methods at the edge of the base plate and the enclosure plate 2, the shape and size of which match the positioning groove 1 on the supporting base pole. The first protruding plate is inserted into the positioning groove 1, which means that the first protruding plate is precisely inserted into the preset groove on the pole, realizing a tight fit and fixed connection between the base plate, the enclosure plate 2 and the supporting base pole.

[0033] The solution proposed in this application effectively solves the structural openness problem that may exist when the camping box is composed only of poles by adding a bottom plate and a protective plate 2 to the load-bearing base and utilizing the interlocking fit between the first convex plate and the positioning groove 1. Specifically, the bottom plate makes the bottom of the camping box form a complete flat surface, which can stably support the items inside the box and prevent small items from falling out from the bottom; the two protective plates 2 enclose the internal space of the box from both sides, effectively preventing items from sliding sideways or falling out. The interlocking method of the first convex plate and the positioning groove 1 not only simplifies the installation process, but also significantly enhances the connection strength and overall stability between the bottom plate and the protective plate 2 and the load-bearing base poles through the interlocking of the structures, avoiding the structural weaknesses or installation inconveniences that may be caused by traditional bolt or welding methods.

[0034] As one embodiment of the present invention, the plate-shaped assembly includes a panel 3. One end of the plate-shaped assembly forms a second protruding plate by opening a slot, and the second protruding plate is inserted into the positioning slot 1 on the supporting base rod. The other end of the plate-shaped assembly is connected to the positioning slot 1 on the adjusting unit rod through a connector 15.

[0035] The second protruding plate refers to a protruding structure formed at one end of the plate-shaped assembly. Its size and shape are adapted to the positioning groove 1 on the supporting base rod. By inserting the second protruding plate into the positioning groove 1, the plate-shaped assembly and the supporting base can be quickly connected and fixed. The connector 15 is used to connect the other end of the plate-shaped assembly to the positioning groove 1 on the adjusting unit rod, further enhancing the stability of the connection. Figure 2 The size of the plate-shaped component does not require an adjustment unit. The connector 15 on the plate-shaped component can be directly connected to the positioning groove 1 on the rod of the supporting base. Through the above technical solution, the connection strength and stability between the plate-shaped component and the supporting base can be improved, and the impact resistance and service life of the camping box can be enhanced. In addition, the connection structure also has the advantages of convenient installation and quick disassembly, which makes it convenient for users to adjust the position and function of the plate-shaped component according to actual needs.

[0036] As one embodiment of this utility model, two corresponding planar wooden board connectors 4 are respectively installed on the ends of the two panels 3 away from the connector 15. At least one panel 3 has folding and telescopic table legs 5 mounted on its surface.

[0037] The planar wood connector 4 refers to a prior art connecting device for connecting two planar wood boards. It can take various forms such as dovetail joints and butterfly snaps. This application does not make a specific limitation on it, as long as it can achieve a stable connection when the two panels 3 are joined. The folding telescopic table leg 5 refers to a table leg that can be rotated, folded for storage, and telescopically adjusted in height. It can be made of various materials such as aluminum alloy and stainless steel. This application does not make a specific limitation on it either, as long as it can support the panel 3 and adjust the height.

[0038] Specifically, when the camping box needs to be used as a tabletop, the two panels 3 are first connected together using the flat wooden board connector 4 to form a larger tabletop. Then, the folding telescopic table legs 5 are unfolded and adjusted to a suitable height to form a stable tabletop. Since the flat wooden board connector 4 effectively prevents wobbling between the two panels 3, and the folding telescopic table legs 5 provide stable support, this solution can significantly improve the stability of the camping box when used as a tabletop.

[0039] As one embodiment of this utility model, a support member 6 is provided on one side of the upper part of the support base. One end of the support member 6 is fixed in the positioning groove 1 on the support base rod. The support member 6 is used to support the panel 3 in the unfolded state and maintain the stability of the panel 3 in the unfolded state.

[0040] The load-bearing component 6 refers to a structural member capable of bearing weight and providing support. Its specific form can be selected according to actual needs; for example, it can be made of metal rods, plastic sheets, or other materials with sufficient strength. The main function of the load-bearing component 6 here is to provide additional support for the unfolded panel 3, preventing it from tilting or swaying.

[0041] Specifically, one end of the support member 6 is fixed in the positioning groove 1 on the support base rod by means of embedding or snap-fit, thereby forming a stable connection with the support base. The other end of the support member 6 extends to the bottom of the panel 3 to support the panel 3. When the panel 3 is in the unfolded state, the support member 6 can effectively distribute the weight borne by the panel 3, preventing the panel 3 from deforming or tilting due to excessive force.

[0042] As one embodiment of this utility model, the upper side wall of the enclosure panel 2 is provided with an opening 7.

[0043] The enclosure panel 2, as a component of the load-bearing base, primarily provides lateral protection and support, and also serves as the side wall of the camping box. The opening 7 refers to a hole or notch provided on the upper side wall of the enclosure panel 2; its size and shape should be suitable for human hand insertion to facilitate gripping and lifting of the camping box.

[0044] Understandably, the shape of the opening 7 can be designed according to actual needs, such as being circular, elliptical, rectangular, or irregular. The size of the opening 7 should be moderate, ensuring that hands can be inserted smoothly while avoiding an opening that is too large and would affect the strength and stability of the enclosure panel 2. As a preferred embodiment, to improve user comfort, the edges of the opening 7 can be chamfered or rounded to avoid scratching hands.

[0045] As one embodiment of this utility model, a bearing strip 8 is symmetrically arranged in the positioning groove 1 on the inner surface of the upper rod of the bearing base, and an IGT module function board is arranged on the bearing strip 8. The IGT module function board is embedded in the upper part of the bearing base.

[0046] The supporting strip 8 is a structural component used to support the IGT module functional panels. It is symmetrically arranged within the positioning groove 1 on the inner surface of the upper rod of the supporting base, ensuring the stability and balance of the IGT module functional panels during installation. The IGT module functional panels are modular panels integrating multiple functions, such as stoves, tea trays, and storage boxes. Users can choose different IGT module functional panels for installation and replacement according to their needs, thus achieving functional customization of the camping box. As a preferred implementation, the IGT module functional panels can be installed in an embedded manner, flush with the upper part of the supporting base, thereby ensuring the overall aesthetics and safety of the camping box.

[0047] As one embodiment of this utility model, it also includes: The outer frame 9 and drawer 10 are arranged in a sliding manner inside the outer frame 9. Multiple outer frames 9 are stacked. Multiple positioning posts are provided at the bottom of the outer frame 9. Positioning holes corresponding to the positioning posts are provided on the bottom plate and the top of the outer frame 9. The position of the adjustment unit corresponds to the width of the outer frame 9.

[0048] The outer frame 9 serves as the housing structure for the drawer 10. Multiple positioning posts at its bottom engage with positioning holes on the bottom plate and the top of the outer frame 9, ensuring stable stacking of multiple outer frames 9. The drawer 10 stores various camping equipment and slides within the outer frame 9 for easy access. The position of the adjustment unit corresponds to the width of the outer frame 9, ensuring the correct installation position of the outer frame 9 within the camping box and preventing interference.

[0049] This application's solution integrates previously scattered camping equipment through the combination of outer frame 9 and drawer 10, achieving categorized storage and allowing users to quickly find the items they need. Simultaneously, the stacking design between outer frames 9 fully utilizes the vertical space of the camping box, improving space utilization. The cooperation of positioning posts and positioning holes ensures the stability of the stacked structure, avoiding the risk of tipping over. The correspondence between the adjustment unit and the width of the outer frame 9 ensures the accuracy of the outer frame 9 installation and the overall integrity of the structure.

[0050] A trailer includes a chassis 11, a steering plate 12 mounted on the bottom of the chassis 11 via a steering bearing, two front wheels mounted on the bottom of the steering plate 12 via a front bracket, two rear wheels mounted on the bottom of the chassis 11 via a rear bracket, and a pulling unit 16 provided on the steering plate 12 via a connecting assembly, the pulling unit 16 being configured to pull the steering plate 12 to rotate.

[0051] In this application, a steering plate 12 is installed at the bottom of the chassis 11, with two front wheels installed at the bottom of the steering plate 12 and two rear wheels installed at the bottom of the chassis 11, thereby enabling the trailer function. By pulling the pulling unit 16, the steering plate 12 can be rotated, thereby changing the direction of the front wheels and turning the trailer. This, in turn, can also turn the camping box, saving time and effort. The pulling unit 16 is a telescopic iron rod, and magnets are installed on the surface of the enclosure 2 near the pulling unit 16. By using the magnets to attract the iron rod, it is convenient to vertically attract the iron rod to one side of the enclosure 2 when outdoors, preventing one end of the iron rod from dragging to the ground and affecting the aesthetics.

[0052] As one embodiment of the present invention, the connecting component includes two lifting lugs installed at the bottom front end of the chassis 11. The chassis 11 has a clearance opening 13 located between the two lifting lugs. The pulling unit 16 is rotatably connected between the two lifting lugs, and the clearance opening 13 is used to allow clearance for the rod of the pulling unit 16.

[0053] By providing a clearance opening 13, the pull unit 16 can be rotated. When placing and storing the unit, the pull unit 16 can be rotated to the bottom of the chassis 11 for placement, reducing storage space.

[0054] As one embodiment of this utility model, a plurality of positioning pins 14 are provided above the chassis 11, and the positioning pins 14 are located in the positioning groove 1 of the bottom rod of the bearing base.

[0055] By setting a positioning pin 14 on the chassis 11, when the camping box is placed on the chassis 11, the positioning pin 14 will be inserted into the positioning groove 1 of the bottom rod of the supporting base, thereby limiting the camping box and achieving stable placement of the camping box.

[0056] Working principle of this utility model: In designing this camping box, an adjustment unit is incorporated into the supporting base. Based on the installation position of the adjustment unit, a panel 3 of suitable size is selected as the side panel of the camping box for installation. The connector 15 on the panel 3 is engaged with the positioning groove 1 on the adjustment unit rod or with the positioning groove 1 on a nearby rod in the supporting base, thus achieving stable installation of the panel 3 as the side panel of the camping box. The IGT module functional panel at the top of the supporting base refers to a modular panel integrating multiple functions, such as a stove, a drain tray, and a storage box. Users can choose different IGT module functional panels for installation and replacement according to their needs, thereby achieving functional customization of the camping box. When camping, the camping box is moved onto the chassis 11 in the trailer, allowing the positioning pin 14 on the chassis 11 to be inserted into the positioning groove 1 on the bottom rod of the supporting base. This limits the placement of the camping box, ensuring its stability. The user then pulls the pulling unit 16 on the trailer to move the camping box. The pulling unit 16 also rotates the steering plate 12, changing the direction of the front wheels and turning the trailer, saving time and effort. Upon reaching the camping location, the two panels 3 are removed from the support base and horizontally connected using the flat wooden board connector 4 to form a large tabletop. One end of the connected panels 3 is placed on the two support members 6. The connector 15 at the bottom of the panels 3 is then connected to the positioning groove 1 of the adjacent rod above the support base, improving the stability of the connection between the panels 3 and the support base and enabling the panels 3 to be used as a tabletop. The folding telescopic table legs 5 are then unfolded and adjusted to a suitable height, forming a stable tabletop for camping use.
