Description

Technical Field

[0001] This utility model relates to the field of campervan technology, and in particular to an expandable campervan. Background Technology

[0002] With the increasing popularity of outdoor camping, campervans, as mobile vehicles integrating transportation, accommodation, and leisure functions, have gained favor among camping enthusiasts. In recent years, family camping and long-distance self-driving camping have gradually emerged, leading users to place higher demands on the functionality and space utilization of campervans. During camping, people not only need comfortable resting areas but also sufficient space to store camping equipment, food, outdoor tools, and other items. They also hope that vehicles can flexibly expand their functionality according to different scenarios, such as quickly setting up temporary tables and storage platforms at campsites. Therefore, developing campervans with good expandability and ample storage space has become an important direction for industry development, meeting diverse camping needs while enhancing the convenience and comfort of the camping experience.

[0003] Existing campervans typically employ a fixed cabin layout in their structural design, featuring basic infrastructure such as simple storage compartments, folding seats, and beds. Their expansion capabilities are primarily achieved through external attachments like roof racks and rear racks. Some models include simple, outward-folding platforms on the sides of the cabin, but these platforms are often single-structure components with limited load-bearing capacity and restricted usage scenarios. Technically, these expansion structures rely heavily on hinge connections for folding and are secured with clips or bolts. The overall design is relatively simple, primarily considering structural stability and basic load-bearing requirements, without being specifically optimized for diverse item placement and multi-functional scene transformations. This results in a limited range of expansion methods, making it difficult to adapt to the flexible spatial and functional needs of different camping scenarios.

[0004] However, existing campervans suffer from limited functionality and storage space, as well as poor expandability. Because the fixed structures occupy most of the interior space, the area available for storing different types of items is very limited, often resulting in cluttered and inconveniently accessible camping equipment, food, and tools. Furthermore, their expandable structures lack flexibility, failing to quickly transform into platforms with different functions according to actual needs. For example, it's difficult to simultaneously create multiple shelves of varying heights for categorized storage, and the expanded space utilization is low, failing to meet users' diverse storage and functional needs during camping. This significantly limits the practicality of the campervan and the user's camping experience. Therefore, an expandable campervan is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an expandable campervan, which aims to improve the problems of limited functionality and storage space, and poor expandability of existing campervans.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An expandable campervan includes a campervan, a push rod rotatably connected to one side of the campervan's outer wall, a pull rod rotatably connected to the other side of the campervan, wheels fixedly connected to the bottom of the campervan, and an expansion assembly provided on the top of the campervan;

[0008] The extended components include a canopy, a second-layer panel, and a third-layer panel. The four corners of the canopy are slidably connected to the interior of the campervan. Multiple elastic blocks are fixedly connected to the top of the campervan. A flat-folding table and an egg roll table are provided on the top of the campervan. Multiple connecting rods are fixedly connected to the bottom of the flat-folding table and the egg roll table. The outer walls of the connecting rods are slidably connected to the interior of the elastic blocks. The second-layer panel and the third-layer panel are located inside the campervan. A disassembly assembly is fixedly connected to the outer wall of the campervan. The rear door is used to close the bottom.

[0009] As a further description of the above technical solution:

[0010] The assembly / disassembly components include a mounting bracket and a locking post, with the outer wall of the mounting bracket fixedly connected to the outer wall of the campervan.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the card post is slidably connected to the inside of the fixing frame, and the outer wall of the card post is slidably connected to the inside of the canopy.

[0013] As a further description of the above technical solution:

[0014] A stop block is fixedly connected to the inner wall of the fixed frame, and a knob is fixedly connected to one end of the locking post.

[0015] As a further description of the above technical solution:

[0016] A limiting post is fixedly connected to the outer wall of the locking post, and the limiting post is in contact with the stop block.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the locking pin is rotatably connected to a limiting ring, and the outer wall of the limiting ring is slidably connected inside the fixing frame.

[0019] As a further description of the above technical solution:

[0020] A spring is fitted on the outer wall of the locking post. One end of the spring is fixedly connected to the outer wall of the limiting ring, and the other end of the spring is fixedly connected to the inner wall of the fixing frame.

[0021] As a further description of the above technical solution:

[0022] The campervan's outer wall is equipped with a support assembly, which includes multiple support rods. One end of each support rod is rotatably connected to the campervan's outer wall, and the other ends of the support rods on both sides are connected to each other to form a V-shaped structure for stable support. The connection point is connected to the bottom side of the second-layer panel.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, different shelves are formed by the flat folding tabletop, the second-layer board, the third-layer board and the egg roll table, which can hold different items and increase the storage capacity. Furthermore, the flat folding tabletop and the egg roll table can be easily replaced by connecting rods and elastic blocks. At the same time, the canopy can provide shelter, which solves the problem of limited functions and storage space and poor expansion effect of traditional campervans, and improves the expandability of campervans.

[0025] 2. In this utility model, the locking post achieves its sliding function by pulling the knob. When the knob is pulled, the knob drives the locking post and the limiting ring, and in conjunction with the spring, the locking post slides inside the canopy, thereby facilitating the disassembly and assembly of the canopy. This makes it convenient for maintenance, replacement, and movement, and solves the problem that existing canopy disassembly and assembly require multiple tools and cannot be easily disassembled, thus improving the convenience of canopy disassembly and assembly.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-4 This utility model provides one embodiment: an expandable campervan, including a campervan 1. The campervan 1 is constructed entirely of a high-strength aluminum alloy frame and ABS engineering plastic panels. The aluminum alloy frame enhances the overall load-bearing capacity and deformation resistance of the structure, while the ABS panels are wear-resistant and waterproof, adaptable to complex outdoor environments (this is common knowledge and will not be elaborated further here). A push rod 2 is rotatably connected to one side of the outer wall of the campervan 1. The push rod 2 is made of retractable stainless steel and has an anti-slip rubber sleeve on its surface to increase the user's grip. The friction during gripping prevents slippage during pushing and improves operational stability. A pull rod 5 is rotatably connected to the other side of the campervan 1. The pull rod 5 is made of high-strength carbon fiber, which is lightweight and has a strong load-bearing capacity, making it easy for users to pull the campervan 1. The bottom of the campervan 1 is fixedly connected to rollers 8, which are rubber inflatable wheels. The rubber material has a good shock absorption effect, and the inflatable structure can adapt to the bumps on different road surfaces. Together with the push rod 2 and pull rod 5, the campervan 1 is more stable and effortless to move in campsites or outdoor areas. An extension component is set on the top of the campervan 1.

[0035] The expansion components include a canopy 3, a second-layer panel 6, and a third-layer panel 7. The canopy 3 is slidably connected to the interior of the campervan 1 at all four corners. The canopy 3 is made of Oxford cloth, which is waterproof, sun-proof, and wear-resistant, providing shade and shelter for the campervan 1 and preventing camping items from getting wet or exposed to direct sunlight. Multiple elastic clips 11 are fixedly connected to the top of the campervan 1. Each elastic clip 11 consists of a high-strength elastic plate and a wear-resistant plastic shell. The elastic plate provides elastic clamping force, while the plastic shell provides protection and guidance, achieving a stable clamping effect on the connecting rods 10. The top of the campervan 1 is equipped with a flat-folding tabletop 4 and an egg roll table 9. Multiple connecting rods 10 are fixedly connected to the bottom of both the flat-folding tabletop 4 and the egg roll table 9. The folding tabletop 4 is made of bamboo composite board. Bamboo is environmentally friendly and has high hardness. Its surface is coated with waterproof paint and is used to temporarily place small items such as water cups and snacks. The egg roll table 9 consists of an aluminum alloy frame and an Oxford cloth tabletop. The aluminum alloy frame is lightweight and sturdy, and the Oxford cloth tabletop can be folded for storage. It is used to place tableware and food when dining outdoors. The connecting rod 10 is slidably connected to the elastic block 11 inside. The second-layer board 6 and the third-layer board 7 are installed inside the campervan 1. The campervan 1 is fixedly connected to the outer wall with disassembly and assembly components. The rear door 20 is used to close the bottom. The outer layer is made of 3mm thick aluminum alloy, and the middle is filled with polyurethane foam material. The aluminum alloy is used to improve the overall structural strength and impact resistance. The PVC board has good waterproof properties. One side of the rear door 20 is connected to the rear of the campervan 1 by a hinge. The hinge is made of stainless steel and has good rust resistance, which can ensure that the rear door 20 can rotate freely for a long time. The rear door 20 is used to close the bottom space of the campervan 1. When the campervan 1 is moved or not in use, closing the rear door 20 can prevent items inside from falling out and reduce unnecessary losses. Simultaneously, when the campervan 1 is placed horizontally, longer items can be placed, increasing storage space. The outer wall of the campervan 1 is equipped with a support assembly, which includes multiple support rods 19. The support rods 19 are hollow cylindrical structures made of high-strength aluminum alloy. The hollow design ensures load-bearing capacity while reducing weight, and the aluminum alloy material combines corrosion resistance and high strength, adapting to the changing outdoor environment. One end of the multiple support rods 19 is rotatably connected to the outer wall of the campervan 1, and the other ends of the two support rods 19 are connected to each other, forming a V-shaped structure. They are connected to each other by bolts, forming a symmetrical V-shaped structure. The triangular structure utilizes the stability principle of triangles to distribute the pressure transmitted by the second-layer panel 6, providing stable support and preventing it from bending or breaking due to excessive load. The connection point is made of zinc alloy, which has good load-bearing capacity and wear resistance, and connects to the bottom side of the second-layer panel 6. When the second-layer panel 6 is unfolded, the support rod 19 works with the hinge to adjust the angle, ensuring that the second-layer panel 6 remains horizontal. This achieves stable support for the second-layer panel 6, enhancing its load-bearing capacity and allowing it to safely hold a large number of items, such as camping cookware and food.When the second-layer panel 6 is not needed, the support rod 19 can be rotated to store it on the outer wall of the campervan 1, reducing space occupation.

[0036] Reference Figure 1 and Figure 5 The assembly / disassembly system includes a mounting bracket 13 and locking posts 16. The outer wall of the mounting bracket 13 is fixedly connected to the outer wall of the campervan 1. The mounting bracket 13 is a rectangular steel structure with high strength and good stability, providing an installation foundation and support for the entire assembly / disassembly system, ensuring that the components do not shake or shift during operation. The outer wall of the locking posts 16 is slidably connected to the inside of the mounting bracket 13. The outer wall of the locking posts 16 is slidably connected to the inside of the canopy 3 through locking holes at the four corners of the canopy 3. The locking holes cooperate with the locking posts 16 to fix the canopy 3 and prevent it from falling off during use. The inner wall of the mounting bracket 13 is fixedly connected to a stop block 18, which is made of metal. It has a rectangular structure and is used to cooperate with the limiting post 17 to limit the locking post 16 and prevent the locking post 16 from sliding out of the fixed frame 13. One end of the locking post 16 is fixedly connected to a knob 12. The knob 12 is made of circular plastic and has anti-slip texture on its surface. The anti-slip texture is used to increase the friction when the user turns the knob 12 for easy operation. The limiting post 17 is fixedly connected to the outer wall of the locking post 16. The limiting post 17 is in contact with the stop block 18. The outer wall of the locking post 16 is rotatably connected to a limiting ring 15. The outer wall of the limiting ring 15 is slidably connected to the inside of the fixed frame 13. A spring 14 is sleeved on the outer wall of the locking post 16. One end of the spring 14 is fixedly connected to the outer wall of the limiting ring 15, and the other end of the spring 14 is fixedly connected to the inner wall of the fixed frame 13.

[0037] Working principle: When using the campervan 1, its movement is very flexible. With the help of the push rod 2 and pull rod 5, the user can easily push or pull the vehicle, making it convenient to adjust its position within the campsite or to transport items over short distances. The second and third shelves 6 and 7 inside the vehicle form multiple storage spaces, allowing for the categorized storage of various camping items. For example, food can be placed on the second shelf 6, and outdoor tools on the third shelf 7. This not only increases the overall storage capacity but also makes the items more organized and improves the overall usability.

[0038] Depending on the usage scenario, the flat-folding tabletop 4 and the egg roll table 9 can be flexibly combined. Simply insert the connecting rod 10 into the elastic clip 11 to quickly fix the flat-folding tabletop 4 or the egg roll table 9. If outdoor dining is required, installing the egg roll table 9 provides a larger dining area; if it is just for temporarily placing small items, the flat-folding tabletop 4 saves more space, fully adapting to diverse usage needs. When the campervan 1 is not in use, it can be folded up, greatly reducing its footprint and making it easy to move and store, saving storage space. In addition, the awning 3 can effectively block rain and sun, providing a comfortable shaded and rain-protected space for camping activities and enhancing the camping experience.

[0039] When it is necessary to disassemble or assemble the canopy 3, the operation steps are simple and convenient. First, pull the knob 12. The knob 12 will cause the locking post 16 to slide inside the fixing frame 13, so that the locking post 16 slides out of the canopy 3. At the same time, it will cause the limiting ring 15 to move, compressing the spring 14. At this time, the limiting post 17 will move to the other side of the stop block 18. Then, turn the knob 12 to make the limiting post 17 contact and engage with the stop block 18, thus maintaining the stability of the structure. Then the canopy 3 can be removed for movement or maintenance. When it is necessary to reinstall the canopy 3, turn the knob 12 back to release the limiting post 17 from the stop block 18. The spring 14 will rebound and cause the locking post 16 to slide back into the canopy 3, thus fixing the canopy 3 and ensuring its stability during use.
