Description

TECHNICAL FIELD

[0001] The utility model relates to a camping equipment, concretely relates to a camping folding car. BACKGROUND

[0002] At present, the camping folding car is widely used in the outdoor camping activities, but the existing camping folding car has certain deficiency in the structural design. The common camping folding car usually only has the basic folding car body, the function is relatively single, and lacks the flexible auxiliary support structure. For example, when the camping folding car needs to be used in some specific scene, such as placing articles on uneven ground or as a simple work platform, stable and reliable support cannot be provided.

[0003] In addition, the storage and fixing mode of the support part is not convenient and reasonable enough. In the prior art, there can be no special part for storing the disassembled support part, so that the support part is easy to lose or placed disorderly during carrying. Moreover, the fixing mode of the folding frame is relatively simple, and the folding frame can shake during use due to insecure fixing, which affects the use safety and stability. At the same time, for some parts related to support, such as the bottom of the support rod and the contact area of the ground, the design is unreasonable, and the support effect is affected when used on soft ground. In terms of material and structural design, the existing camping folding car also has optimization space, for example, the material selection can not be durable enough, and the structural strength is insufficient, which affects the service life and overall performance of the folding car. SUMMARY

[0004] The utility model aims at the above-mentioned problems existing in the prior art, and provides a camping folding car.

[0005] In order to realize the above-mentioned application purpose, the utility model adopts the following technical scheme: a camping folding car includes a folding car body, and further includes:

[0006] A first folding frame is rotatably connected to the bottom of one end of the folding car body, can be turned from a horizontal state to a vertical state, and can be fixed on the folding car body by a first clamping piece in the vertical state;

[0007] A second folding frame is rotatably connected to the end of the first folding frame away from the folding car body, can be parallel and perpendicular to the first folding frame and turned and adjusted between the two states;

[0008] A support rod can be screw-connected and installed on the first folding frame and the second folding frame, and is used as a support piece;

[0009] A second clamping piece can be detachably installed on the first folding frame or the second folding frame or the folding car body, and is used for installing the support rod disassembled from the first folding frame and the second folding frame.

[0010] Furthermore, the second fastener has a locking hole, and the locking hole is interference-fitted with the support rod to fix the support rod.

[0011] Furthermore, the locking hole and the support rod are magnetically engaged.

[0012] Furthermore, the bottom of the support rod is equipped with a detachable base to increase the contact area between the support rod and the ground.

[0013] Furthermore, the base is an adjustable height base, and the height can be adjusted by rotating to adjust the length of the screw connection between the base and the support rod.

[0014] Furthermore, the folding frame is also equipped with a rotatable hook, and the first folding frame is equipped with a hanging shaft that cooperates with the hook. When the first folding frame is in a vertical position, the hanging shaft can be hooked by the hook to further fix the first folding frame.

[0015] Furthermore, the support rod is made of stainless steel.

[0016] Furthermore, the cross-section of the support rod is circular.

[0017] Furthermore, the first folding frame is welded together from multiple square or round tubes, and the first folding frame is provided with at least two reinforcing ribs.

[0018] Furthermore, a limiting link is provided between the first folding frame and the folding vehicle body, which limits the flipping angle of the first folding frame. The limiting link is provided with a sliding groove, and the first folding frame is provided with a slider that cooperates with the sliding groove.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Flexible support structure: By setting up a first folding frame that can be flipped and fixed, a second folding frame that can be flipped and adjusted parallel and perpendicular to the first folding frame, and a support rod that can be screwed onto both, the camping folding bike can flexibly adjust the support structure according to different usage scenarios and needs, which enhances the functionality and adaptability of the camping folding bike, such as providing stable support on uneven ground.

[0021] 2. Convenient storage of support rods: The second fastener can be detachably installed on the first folding frame, the second folding frame, or the folding vehicle body. The fastener has a locking hole that fits the support rod with an interference fit. The locking hole and the support rod can even be magnetically attached. This provides a convenient and reliable way to store the disassembled support rods, effectively preventing the support rods from being lost or misplaced during transport.

[0022] 3. Optimized support rod bottom design: The bottom of the support rod features a detachable base, increasing the contact area between the support rod and the ground. This effectively prevents the support rod from sinking on soft surfaces, improving support stability. Furthermore, the base is height-adjustable; the height can be adjusted by rotating and changing the length of the screw connection between the base and the support rod, further enhancing adaptability to different ground conditions.

[0023] 4. Stable folding frame fixation: The folding frame is equipped with a rotatable hook, and the first folding frame is equipped with a hanging shaft that cooperates with the hook. When the first folding frame is in a vertical position, the hook hooks onto the hanging shaft, thereby further fixing the first folding frame. This greatly improves the stability of the folding frame during use, avoids shaking due to insecure fixing, and ensures safe use.

[0024] 5. Excellent Material and Structural Design: The support rod is made of stainless steel, ensuring its strength and durability and extending its service life. The support rod has a circular cross-section, which facilitates processing and installation while ensuring support strength. The first folding frame is welded from multiple square or round tubes and has at least two reinforcing ribs, which improves the structural strength of the first folding frame and further enhances the overall stability and reliability of the camping folding vehicle.

[0025] 6. Reasonable limiting design: A limiting link is provided between the first folding frame and the folding vehicle body. The limiting link restricts the flipping angle of the first folding frame. The limiting link is provided with a sliding groove, and the first folding frame is provided with a slider that cooperates with the sliding groove. This design not only ensures the accuracy and controllability of the flipping angle of the first folding frame, but also disperses the force to a certain extent and improves the stability of the entire structure.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0036] Example 1: Basic Structure Demonstration

[0037] In this embodiment, as Figures 1-6 As shown, the folding frame 7 of the camping folding vehicle is made of high-strength aluminum alloy to ensure sufficient strength while reducing overall weight for easy carrying. The main structure of the folding frame 7 is existing technology, such as its foldable structure, the wheels at the bottom, and the retractable handlebars. These are all existing technologies and their structures and principles will not be elaborated here. The improvements of this utility model are as follows:

[0038] The first folding frame 1 is welded from multiple round or square tubes, and one end of it is rotatably connected to the bottom of one end of the folding vehicle body 7 via a high-strength rotating shaft. This connection method allows the first folding frame 1 to easily flip from a horizontal to a vertical position. When the first folding frame 1 is flipped to the vertical position, it is fixed to the folding vehicle body 7 by the first fastener 3. The first fastener 3 can adopt a snap-on design, which is simple and convenient to operate. It can be fixed with just a light press, and can be quickly released by reversing the operation.

[0039] The second folding frame 2 is also rotatably connected to the end of the first folding frame 1 furthest from the folding vehicle body 7 via a rotating shaft (or a dedicated rotating shaft connector, allowing the second folding frame 2 to stop and start; the specific structure is existing technology and not limited in this invention), enabling the second folding frame 2 to flexibly rotate and adjust between parallel and perpendicular states to the first folding frame 1. In practical use, for example, when the camping folding vehicle needs to be used as a large storage platform, the second folding frame 2 can be adjusted to be perpendicular to the first folding frame 1 to expand the support area.

[0040] The support rod 4 is made of stainless steel with a circular cross-section and a diameter of 20mm. This design ensures that the support rod 4 has sufficient strength to support heavy objects while facilitating screw connection with the first folding frame 1 and the second folding frame 2. Both the first folding frame 1 and the second folding frame 2 are provided with threaded holes that match the support rod 4, allowing for quick installation and removal by rotating the support rod 4.

[0041] The second fastener 5 is a metal plate with a locking hole 51, which is interference-fitted with the support rod 4. The second fastener 5 is detachably installed on the side of the folding vehicle body 7 by bolts. When the support rod 4 is removed, it can be inserted into the locking hole 51 of the second fastener 5 to achieve stable storage of the support rod 4.

[0042] Preferably, such as Figure 7 As shown, a garbage bag holder 9 can also be installed on the first folding frame 1, and garbage bags can be installed on the garbage bag holder 9.

[0043] Example 2: Base 6 and magnetic design

[0044] In this embodiment, based on embodiment 1, the bottom end of the support rod 4 and the second fastener 5 have been further optimized.

[0045] The support rod 4 has a detachable base 6 at its bottom. The base 6 is made of rubber, is circular in shape, and has a diameter of 80mm, which greatly increases the contact area with the ground compared to the diameter of the support rod 4. The base 6 and the support rod 4 are connected by threads. This connection method not only facilitates the disassembly and replacement of the base 6, but also ensures a firm connection during installation.

[0046] Furthermore, the base 6 is a height-adjustable base. The length of the threaded connection between the base 6 and the support rod 4 can be adjusted by rotating the base 6, thus achieving height adjustment. In practical use, when encountering uneven ground, the height of the support rod 4 can be adjusted by rotating the base 6 according to the ground level, ensuring the camping folding vehicle remains level and stable. Preferably, the thread size of the base 6 can be set to match the thread size of the support rod 4. This allows the base 6 to be detached and installed in the mounting holes on the first folding frame 1 and the second folding frame 2 after the support rod 4 is disassembled, facilitating placement of the base 6 and preventing loss.

[0047] For the second fastener 5, in addition to the interference fit between the locking hole 51 and the support rod 4, a magnetic attraction device is also provided on the inner wall of the locking hole 51 and the corresponding part of the support rod 4. Specifically, a ring magnet is embedded in the inner wall of the locking hole 51, and a metal piece that can be attracted by the magnet is placed at the corresponding position of the support rod 4. In this way, when the support rod 4 is inserted into the locking hole 51, the magnetic attraction can further enhance the fixing effect of the support rod 4, and even in a bumpy environment, the support rod 4 is not easy to fall out of the locking hole 51.

[0048] Example 3: Hook 71 and Limiting Design

[0049] In this embodiment, based on Embodiments 1 and 2, the design and application of hook 71 and limiting link 8 are highlighted.

[0050] A rotatable hook 71 is installed on the folding frame 7. The hook 71 is fixed to the side of the folding frame 7 via a small rotating shaft and can rotate freely within a certain angle range. A hanging shaft 11, which engages with the hook 71, is a 10mm diameter metal cylinder welded to the side of the first folding frame 1 closest to the folding frame 7. When the first folding frame 1 is flipped to a vertical position, the hook 71 is rotated to hook onto the hanging shaft 11, thereby further securing the first folding frame 1. This double-fixing method greatly improves the stability of the first folding frame 1 during use and effectively avoids safety hazards caused by shaking.

[0051] A limiting link 8 is provided between the first folding frame 1 and the folding body 7. The limiting link 8 is a metal rod with an adjustable length. One end of the rod is connected to the folding body 7 via a pin, and the other end is provided with a groove 81. A slider 13 that mates with the groove 81 is welded onto the first folding frame 1. The slider 13 can slide freely within the groove 81. Through this design, the limiting link 8 can effectively limit the flipping angle of the first folding frame 1. In actual use, when the first folding frame 1 flips upward from a horizontal position, the slider 13 slides within the groove 81. When the predetermined flipping angle is reached, the slider 13 will touch the end of the groove 81, thereby preventing the first folding frame 1 from continuing to flip, ensuring the accuracy and controllability of the flipping angle of the first folding frame 1. At the same time, when the first folding frame 1 is subjected to external forces, the limiting link 8 can also play a certain supporting role, distributing the force and improving the stability of the entire structure.

[0052] The parts of this utility model not described in detail are existing technologies, therefore, this utility model does not describe them in detail.

[0053] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0054] Although this document frequently uses terms such as first folding frame 1, second folding frame 2, first fastener 3, support rod 4, second fastener 5, base 6, folding vehicle body 7, limiting link 8, garbage bag bracket 9, hanging shaft 11, reinforcing rib 12, slider 13, locking hole 51, hook 71, and groove 81, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.

[0055] This utility model is not limited to the above-described preferred embodiment. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to this utility model falls within the protection scope of this utility model.
