Description

Technical Field

[0001] This invention relates to the field of outdoor products and camping vehicle technology, and in particular to a foldable camping vehicle. Background Technology

[0002] With the increasing popularity of camping, fishing, outdoor photography, outdoor vending, and other outdoor recreational activities, users typically need to carry tents, tarps, tables and chairs, lights, photography equipment, fishing gear, food, power banks, and other auxiliary equipment. Because these items are numerous, heavy, and irregularly shaped, relying solely on manual transport is not only labor-intensive but also inconvenient to move in sandy, grassy, ​​gravelly, and campsite terrain. Therefore, foldable camping vehicles are widely used for transporting outdoor supplies.

[0003] Most existing campervans only have load-bearing and towing functions, and their structure typically includes a foldable frame, a cloth bag or carrying platform, wheels, and handles. While these campervans can meet basic transportation needs, they still have the following shortcomings in actual outdoor use: First, existing campervans have limited functional expansion capabilities. Users often need to install lighting, contour lights, photography fill lights, ambient lights, tarpaulin supports, fishing oxygenation equipment, second-level storage structures, fishing bags, or other accessories during outdoor activities. However, traditional campervans lack a stable installation base and standardized accessory connection points, resulting in external equipment having to be temporarily tied up or placed separately, leading to poor stability and inconvenience in use.

[0004] Secondly, existing campervans typically lack adequate power supply integration capabilities. Outdoor lighting, supplemental lighting for photography, ambient lighting, oxygen supply equipment, and mobile device charging all require power support, often necessitating users to carry separate power banks. The lack of a reliable connection between the power bank and the vehicle body makes it prone to shaking, collisions, or falling during transport, and also hinders cable management and centralized equipment control.

[0005] Third, the existing accessories for campervans are not convenient to assemble and disassemble. Outdoor usage scenarios change rapidly, and users may switch between transportation, lighting, fishing, shooting, and setting up a stall. If the installation of accessories relies on bolts, cable ties, or complicated fixing methods, not only is the installation inefficient, but disassembly and storage are also inconvenient.

[0006] Fourth, the existing wheel structure of campervans is not adaptable enough to different terrains. Campervans may travel on grass, mud, sand, gravel roads, or paved campground roads, and different scenarios have different requirements for wheel load-bearing capacity, diameter, width, and traction. Traditional wheels are usually fixed structures, which cannot be quickly replaced and are not convenient to adjust according to the usage environment.

[0007] Fifth, the existing campervans lack sufficient handle angle adjustment capabilities. Different users have different heights, and their posture and direction of pulling the vehicle also differ. Fixed handles or handles with limited adjustment range are inconvenient when turning, towing, and storing, affecting the overall vehicle's operational comfort. Summary of the Invention

[0008] The present invention aims to at least partially solve one of the technical problems in the related art.

[0009] Therefore, the purpose of this invention is to propose a foldable camping vehicle to solve the problems of existing camping vehicles, such as weak functional expansion capabilities, inconvenient installation of power supply modules, low efficiency in disassembling and assembling accessories, insufficient wheel adaptability, and limited handle angle.

[0010] To achieve the above objectives, the present invention proposes a foldable camping vehicle, comprising a base frame, a hollow column, a quick-release clamp, a support clamp, quick-release load-bearing wheels, a rotatable handle, and a power battery; the hollow column is mounted on the base frame, the quick-release clamp is mounted on the upper end of the hollow column, the support clamp is mounted on the hollow column, the quick-release load-bearing wheels are detachably mounted on the lower part of the base frame, the rotatable handle is connected to the base frame, and the power battery is mounted at the rear of the vehicle body.

[0011] The present invention discloses a foldable camping vehicle, which forms a foldable load-bearing base through a bottom frame, provides installation positions for outdoor accessories and power supply extensions through hollow columns, enables quick installation and removal of accessories through quick-release clamps, holds external support components through support clamps, improves wheel replacement and adaptability to different terrains through quick-release load-bearing wheels, enhances the convenience of towing angle adjustment through rotatable handles, and provides power support for outdoor electrical equipment through a power battery installed at the rear of the vehicle.

[0012] Specifically, the bottom frame is a foldable load-bearing frame. When unfolded, it is used to carry camping supplies, fishing gear, outdoor equipment, or stall items. When folded, it reduces the overall storage volume of the vehicle. As the basic load-bearing structure of the vehicle, the bottom frame can provide a stable space for placing items when unfolded, and can be folded when not in use for easy storage in the vehicle's trunk, storage compartment, or other storage space.

[0013] Specifically, the hollow column is a circular hollow column, used to install power supply modules, telescopic tubes, lamp brackets, or outdoor extension accessories. The hollow column can serve as a vertical support foundation, and its internal hollow structure can be used to reduce weight, accommodate connecting structures, or facilitate power line layout. Its exterior can provide installation positions for quick-release clamps and support fixtures.

[0014] Specifically, the hollow column can be connected to a telescopic tube, which can extend or retract relative to the hollow column to form a height-adjustable support structure. In use, the telescopic tube extends upward to raise the installation height of the accessory; when stored, the telescopic tube retracts to a position close to the hollow column, thereby reducing the space occupied.

[0015] Specifically, multiple telescopic tubes can be configured, each with an independently adjustable height. Once extended, they are used to hang outdoor lighting, supplemental lighting for photography, canopies, oxygenation equipment, ambient lighting, or other outdoor electrical equipment. With multiple height-adjustable support positions, the needs for nighttime lighting, supplemental lighting for photography, campsite atmosphere setup, power supply for fishing oxygenation, and the installation of other outdoor equipment can be met.

[0016] Specifically, the quick-release chuck includes a clamping part and a locking part. The clamping part is used to clamp external accessories, and the locking part is used to enable quick installation and quick removal of external accessories relative to the hollow column. The quick-release chuck is located at the upper end of the hollow column, which can make full use of the vertical height of the hollow column to provide stable support for lamps, supports, or other accessories at a higher position.

[0017] Specifically, the quick-release chuck is a replaceable structure, capable of being replaced with chucks, fasteners, or accessory connectors of different specifications to adapt to second-layer storage structures, fishing bags, lamp brackets, or other outdoor accessories. By changing different types of quick-release chucks, users can switch between different accessories according to actual scenarios without changing the main structure of the bottom frame or hollow column, improving the overall vehicle versatility.

[0018] Specifically, the support clamp is located on the side of the hollow column. The support clamp is used to hold the central support rod of the canopy, external hardware brackets, storage platform brackets, or barbecue support accessories to improve the stability of the external structure. Since the support clamp is installed on the hollow column, its clamping direction and height can be arranged around the installation position of the hollow column, thereby forming a relatively stable connection between the external support components and the vehicle body.

[0019] Specifically, the quick-release load-bearing wheel includes a wheel body, an axle connector, and a quick-release locking mechanism. The quick-release locking mechanism allows for quick assembly and disassembly of the wheel body relative to the base frame, and enables the replacement of different specifications of load-bearing wheels according to the usage scenario. Users can select appropriate specifications of quick-release load-bearing wheels based on different ground environments such as sand, grass, hardened roads, or gravel roads to improve passability and load-bearing stability.

[0020] Specifically, the rotatable handle includes a handle body, a rotating connector, and a locking mechanism. The handle body can adjust the pulling angle relative to the base frame via the rotating connector and is fixed at a predetermined angle by the locking mechanism to accommodate different heights, different pulling directions, and different usage postures. The rotatable handle facilitates users in adjusting the force angle when dragging and also makes it easy to rotate to a position close to the base frame when storing, reducing space occupation.

[0021] Specifically, the power battery is a detachable battery installed at the rear of the vehicle body and used to power lighting, drone charging, outdoor cooking, ambient lighting, or other outdoor electrical equipment. Installing the power battery at the rear of the vehicle body avoids occupying the main load-bearing space of the bottom frame, while also facilitating installation, removal, charging, or connection of external electrical equipment by the user from the rear of the vehicle.

[0022] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: 1. This invention, by setting hollow columns on the bottom frame, enables the campervan to not only have a transport function, but also a vertical expansion installation foundation, which can be used for the installation of outdoor lighting fixtures, supplementary lighting equipment, canopy support components, oxygenation equipment and other accessories.

[0023] 2. This invention, by installing a quick-release clamp on the upper end of the hollow column, facilitates users to quickly install or remove external accessories from a higher position, reducing cumbersome operations such as bolt fixing and binding, and improving outdoor use efficiency.

[0024] 3. By installing the support clamp on the hollow column, the present invention can clamp and support the central support rod of the canopy, the external hardware bracket, the storage platform bracket or the barbecue support accessory, thereby improving the stability between the external structure and the vehicle body.

[0025] 4. By installing the power battery at the rear of the vehicle body, this invention can provide power support for outdoor power needs such as lighting, shooting, fishing, cooking, and atmosphere setting without significantly occupying the main load-bearing space of the bottom frame.

[0026] 5. By setting up quick-release load-bearing wheels, the present invention allows users to quickly change the wheel body to fit different terrain environments, improving the camper's ability to pass through sand, grass, mud, gravel roads and campsite roads. By setting up a rotatable handle, the angle can be adjusted according to the user's height, pulling direction and storage needs, improving towing comfort and storage convenience.

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0029] like Figures 1 to 5 As shown in the accompanying drawings, a foldable campervan according to an embodiment of the present invention is described below. It mainly includes a base frame 1, a hollow column 2, a quick-release clamp 3, a support clamp 4, quick-release load-bearing wheels 5, a rotatable handle 6, and a power battery 7. The base frame 1 serves as the load-bearing foundation of the entire vehicle. The hollow column 2 is mounted on the base frame 1. The quick-release clamp 3 is mounted on the upper end of the hollow column 2. The support clamp 4 is mounted on the hollow column 2. The quick-release load-bearing wheels 5 are detachably mounted below the base frame 1. The rotatable handle 6 is connected to the base frame 1. The power battery 7 is mounted at the rear of the vehicle body.

[0030] In one embodiment of the invention, the base frame 1 is a foldable support frame. When unfolded, the base frame 1 forms a support area for placing camping supplies, fishing gear, outdoor equipment, stall supplies, or other items. This support area can be used to place commonly used outdoor items such as tents, tarps, tables and chairs, lamps, fishing tackle, food boxes, storage boxes, and power accessories. Folding the base frame 1 reduces the overall size of the campervan, making it easier to store and transport. When not in use, the user can fold the base frame 1, allowing the entire vehicle to be placed in the trunk, storage cabinet, or campsite storage space.

[0031] The base frame 1 needs to have sufficient load-bearing strength in its unfolded state to ensure that the entire vehicle is not easily deformed after loading items. In practice, the base frame 1 can be made of metal tubing, profiles, or other high-strength materials. The folding method of the base frame 1 can be set according to the overall structural needs of the campervan, as long as it can form a stable load-bearing state when unfolded and reduce the storage volume when folded. The base frame 1 not only serves as a place for items but also provides a mounting base for the hollow column 2, quick-release load-bearing wheels 5, and rotatable handle 6. Therefore, the base frame 1 should have reliable connection strength with the above structures.

[0032] In one embodiment of the present invention, the hollow column 2 is mounted on the base frame 1. The hollow column 2 is preferably a circular hollow column. A circular hollow column has good structural stability when the direction of force changes and is easy to integrate with clamping structures. The hollow column 2 serves as the vertical extension base for the campervan, and can be used to install quick-release clamps 3, support clamps 4, and can be used in conjunction with telescopic tubes, lamp holders, or outdoor extension accessories.

[0033] The hollow column 2 has an internal cavity structure, which reduces the overall weight of the vehicle and provides space for power lines, plug-in structures, or other power supply module-related structures. The hollow column 2 can also accommodate a quick-release battery module for powering outdoor lighting, outdoor photography outline lights, fishing oxygenation equipment, ambient lighting, and other electrical devices. By integrating the power supply-related structures with the hollow column 2, the power supply equipment can be better integrated with the campervan body, reducing the inconvenience of users carrying and storing power supplies separately.

[0034] In one embodiment of the invention, the hollow column 2 can be connected to a telescopic tube. The telescopic tube can extend or retract relative to the hollow column 2 to form a height-adjustable support structure. When the user needs to install lighting, supplementary lighting, ambient lighting, or other accessories requiring a certain height, the telescopic tube can extend from the hollow column 2, placing the accessories at a higher position, thereby obtaining a better lighting range or support effect. When the user needs to transport or store the campervan, the telescopic tube can be retracted to lower the overall vehicle height, avoiding the protruding structure occupying space or causing collisions.

[0035] One or more telescopic tubes can be installed. When multiple telescopic tubes are installed, each tube can be adjusted in height independently. Users can arrange different accessories at different heights according to the actual usage scenario. For example, when camping at night, lighting can be installed at a higher position to expand the lighting range; when taking outdoor photos, fill lights or contour lights can be installed at an appropriate height to meet shooting needs; when fishing, oxygenation equipment or related pipelines can be supported in an easy-to-operate position; when setting up a campsite, ambient lights can be arranged at different heights to improve the user experience.

[0036] In one embodiment of the present invention, a quick-release clamp 3 is installed at the upper end of the hollow column 2. The quick-release clamp 3 is used to clamp external accessories and quickly fixes the external accessories relative to the hollow column 2 by locking. Since the quick-release clamp 3 is located at the upper end of the hollow column 2, it can install accessories at a higher position, which is suitable for installing light fixture brackets, supplementary lights, canopy auxiliary supports, or other outdoor accessories that need to be raised.

[0037] The quick-release clamp 3 enables rapid installation and removal. When used outdoors, users can easily install the corresponding accessories onto the upper end of the hollow column 2 without the need for complex tools; when changing usage scenarios or storing the device, the clamp can also be quickly released. The quick-release clamp 3 can be configured with different clamping methods according to the shape and specifications of the accessories to adapt to different external attachments. This structure reduces the instability and inefficiency caused by traditional bolt fixing, strap fixing, or temporary binding.

[0038] In one embodiment of the invention, the quick-release clamp 3 is a replaceable structure. Users can replace the quick-release clamp 3 with clamps, fasteners, or accessory connectors of different specifications as needed to adapt to second-layer storage structures, fishing bags, lamp holders, or other outdoor accessories. For example, in transport mode, the quick-release clamp 3 can be used to secure lighter auxiliary accessories; in lighting mode, it can be used to secure lamps; and in fishing mode, it can be used to secure fishing-related accessories. By replacing and adapting the quick-release clamp 3, the campervan can achieve multi-purpose conversion without altering its main structure.

[0039] In one embodiment of the present invention, the support clamp 4 is mounted on the hollow column 2. The support clamp 4 can be disposed on the side of the hollow column 2 and is used to clamp the central support rod of the canopy, external hardware brackets, storage platform brackets, or barbecue support accessories. Since the hollow column 2 is connected to the bottom frame 1, after the support clamp 4 clamps the external support component, the external structure can form a more stable force relationship with the bottom frame 1 through the hollow column 2, thereby improving the support stability.

[0040] The clamping force of the support clamp 4 should meet the outdoor support requirements. During use, the user can place the poles or brackets requiring support into the clamping area of ​​the support clamp 4 and tighten them to prevent them from wobbling or falling off. The support clamp 4 is installed on the hollow column 2, so that the clamping position is at a certain height relative to the bottom frame 1, which is beneficial for supporting canopies, storage platforms, or other external structures. Compared with temporary binding, the support clamp 4 provides a more stable and orderly connection method.

[0041] In one embodiment of the present invention, the quick-release road wheels 5 are detachably mounted below the base frame 1. The quick-release road wheels 5 support the base frame 1 and drive the entire vehicle. Because outdoor ground environments are complex and different surfaces have different requirements for the wheels, the quick-release road wheels 5 are designed to be detachable, allowing users to replace them with different specifications depending on the environment. For example, on sand or grass, wider or larger diameter quick-release road wheels 5 can be used to improve passability; on paved roads, quick-release road wheels 5 with lower resistance can be used to improve towing efficiency.

[0042] The quick-release road wheel 5's quick-release connection allows users to change wheels without complicated disassembly and assembly. In use, the quick-release road wheel 5 is installed and locked under the base frame 1, enabling it to bear the weight of the base frame 1 and the loaded items. To remove it, simply release the lock to detach the quick-release road wheel 5 from the base frame 1. This design not only facilitates wheel replacement according to terrain but also makes maintenance, cleaning, and storage easier.

[0043] In one embodiment of the invention, a rotatable handle 6 is connected to the base frame 1. The rotatable handle 6 is used by a user to pull the campervan. The rotatable handle 6 can rotate relative to the base frame 1 to adjust the pulling angle. Users of different heights require different handle heights and angles when towing the campervan; when turning, going uphill, downhill, or around obstacles, the handle angle also needs to be adjusted according to the direction of force. By adjusting the angle of the rotatable handle 6, the user can tow the campervan in a more comfortable and effortless manner.

[0044] The rotatable handle 6 can be fixed at a predetermined angle. After the user adjusts the rotatable handle 6 to a suitable angle, it can be locked to keep it stable during towing and prevent vehicle shaking or inconvenience caused by angle changes. When storing, the rotatable handle 6 can be rotated to a position close to the bottom frame 1, thereby reducing the overall size of the vehicle and facilitating placement and transportation.

[0045] In one embodiment of the invention, the power battery 7 is installed at the rear of the vehicle body. The power battery 7 is used to power outdoor electrical equipment. Compared with placing the battery arbitrarily inside the bottom frame 1, installing the power battery 7 at the rear of the vehicle body reduces the occupation of the main load-bearing space of the bottom frame 1, allowing the bottom frame 1 to still be used to place camping items and outdoor equipment. At the same time, the rear position of the vehicle body makes it easier for users to access the power battery 7 from the outside, thereby facilitating the removal, charging, maintenance, and connection of electrical equipment.

[0046] The power battery 7 can be used to power lighting, drone charging, outdoor cooking, ambient lighting, or other outdoor electrical equipment. In camping scenarios, the power battery 7 can power lights mounted on the hollow column 2 or quick-release clamp 3; in outdoor photography scenarios, the power battery 7 can power fill lights or contour lights; in fishing scenarios, the power battery 7 can power aeration equipment for outdoor fishing; and in campsite recreation scenarios, the power battery 7 can power ambient lighting or other small electrical equipment. Because the power battery 7 is mounted on the vehicle body, the risk of shaking and scattering during movement is reduced.

[0047] The usage process of this invention is as follows: Before use, the user unfolds the folded base frame 1 to create a stable load-bearing configuration. Then, depending on the ground conditions, install and lock the appropriate size quick-release load-bearing wheels 5 under the base frame 1. If towing a campervan is required, rotate the rotatable handle 6 to a suitable angle and secure it in an easy-to-pull position. At this point, the user can place tents, tarps, tables and chairs, fishing gear, storage boxes, food, lights, or other outdoor items on the base frame 1.

[0048] When lighting, photography, fishing, or camping setup is required, users can expand the functionality of the hollow column 2. For higher installation positions, the telescopic tube that mates with the hollow column 2 can be extended and adjusted to a suitable height. Then, the quick-release clamp 3, installed at the upper end of the hollow column 2, can be used to clamp and lock light fixtures, supplementary lighting equipment, awning support components, or other accessories. Because the quick-release clamp 3 allows for rapid fixing and disassembly, users can quickly switch accessories according to different usage needs.

[0049] When it is necessary to support the central support rod of the canopy, external hardware brackets, storage platform brackets, or barbecue support accessories, the user can place the corresponding support components into the support clamp 4 and clamp them in place. Since the support clamp 4 is installed on the hollow column 2, the support components can form a connection with the bottom frame 1 through the hollow column 2, thereby improving the stability of the external structure and reducing swaying caused by outdoor wind, personnel collisions, or uneven ground.

[0050] When power is needed, the user can use the power battery 7 installed at the rear of the vehicle. The power battery 7 can provide power to lighting, photography fill lights, ambient lights, fishing oxygenation equipment, drone charging equipment, outdoor cooking equipment, or other outdoor electrical equipment. Because the power battery 7 is installed at the rear of the vehicle, it facilitates connection to external devices and avoids occupying the main loading space on the bottom frame 1. During vehicle movement, the power battery 7 moves with the vehicle body, facilitating centralized management of outdoor electrical equipment.

[0051] After use, the user can first disconnect the power battery 7 from the external electrical equipment, then remove the accessories installed on the quick-release clamp 3, release the support clamp 4 from the external support, and retract the telescopic tube. Next, rotate the rotatable handle 6 to the storage angle, remove the quick-release load-bearing wheels 5 if necessary, and finally fold the bottom frame 1. The folded campervan has a smaller overall size, making it easier to load and store.

[0052] The technical solution in the above-described embodiments of this application utilizes a base frame 1 for supporting and folding the campervan; a hollow column 2 to form a foundation for outdoor accessories and power supply expansion; quick-release clamps 3 for rapid installation and removal of accessories; support clamps 4 for stable clamping of external support components; quick-release load-bearing wheels 5 for quick wheel replacement in different terrains; a rotatable handle 6 for adjustable pulling angle; and a power battery 7 for powering outdoor equipment. The coordinated operation of these structures enables the invention to meet the needs of both transporting items and various usage scenarios such as camping, fishing, photography, lighting, power supply, and outdoor vending, demonstrating high practicality and promotional value.
