Description

Technical Field

[0001] This utility model relates to the field of campervan accessories, specifically a load-bearing front wheel structure and a campervan. Background Technology

[0002] Campervans are widely used for outdoor activities such as camping, picnics, and travel. A campervan typically consists of a frame and a basket. The frame includes a chassis and wheels, which are welded together. All weight is borne by these welded joints. Due to vibrations during operation, and the fact that these welds are prone to incomplete welds that are difficult to detect, they can detach during use, affecting the product's lifespan and user experience. Utility Model Content

[0003] The purpose of this invention is to provide a load-bearing front wheel structure and a campervan to solve the problem of poor load-bearing performance of campervans.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a load-bearing front wheel structure, comprising: Install beams, A square tube with a support lug on one side, the mounting beam being secured between the two support lugs; A top sleeve and a bottom sleeve, wherein the top sleeve is disposed at the top of the square tube and the bottom sleeve is disposed at the bottom of the square tube; A connecting rod is provided with a wheel frame at its lower part, and a roller is rotatably mounted on the wheel frame. The connecting rod extends into the bottom sleeve and the top sleeve in sequence. A locking ring is movably installed inside the top sleeve, and the neck of the connecting rod is engaged in the locking ring.

[0005] Preferably, a welded layer is provided between the mounting beam and the square tube.

[0006] Preferably, the square tube is made by bending a metal sheet.

[0007] Preferably, a locking spring is provided at one end of the locking ring.

[0008] Preferably, the top sleeve is composed of a left cavity and a right cavity.

[0009] This utility model also discloses a campervan, including: a frame body and the aforementioned load-bearing front wheel structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention features a support ear on a square tube, which supports the mounting beam, improving the load-bearing capacity. The support ear also distributes some of the load, significantly reducing stress fatigue at the weld joint, enhancing safety, and effectively extending the service life. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating orientation or position, are based on the orientation or positional relationships shown in the accompanying drawings. They are used 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, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] 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.

[0017] like Figures 1 to 5 As shown, the load-bearing front wheel structure of this embodiment includes: Install beam 1, The square tube 2 has a support lug 21 on one side, and the mounting beam 1 is clamped between the two support lugs 21. It should be noted that the support lugs 21 are generally straight, but can also be angled or reinforced (by adding reinforcing ribs, thickening, etc.). The length and thickness of the upper and lower support lugs 21 can be different (e.g., the lower support lug is longer than the upper support lug, and the lower support lug is thicker than the lower support lug). The mounting beam 1 and the support lugs 21 should be welded together for reinforcement to avoid unsafe conditions caused by clamping gaps.

[0018] Top sleeve 3 and bottom sleeve 4, the top sleeve 3 is set at the top of the square tube 2 and the bottom sleeve 4 is set at the bottom of the square tube 2; The connecting rod 5 has a wheel frame 6 at its lower part, and a roller 7 is rotatably mounted on the wheel frame 6. The connecting rod 5 extends sequentially into the bottom sleeve 4 and the top sleeve 3. The connecting rod 5 and the wheel frame 6 are usually shipped as a single unit after assembly, but can also be assembled by the user (the connection method is usually threaded). The roller 7 is mounted on the wheel frame 6 via a connecting shaft, and movement is achieved by rotating either the connecting shaft or the roller 7 (rotation is achieved by installing bearings).

[0019] The locking ring 8 is movably installed inside the top sleeve 3, and the neck of the connecting rod 5 is engaged in the locking ring 8.

[0020] A welded layer is provided between the mounting beam 1 and the square tube 2. The support lugs only serve as auxiliary supports; the main connection relies on the fixed connection of the welded layer. Therefore, it is necessary to weld the mounting beam 1 and the square tube 2.

[0021] The square tube 2 is made by bending a metal sheet. Using a single metal sheet results in a uniform thickness for the support ears; however, by cutting the sheet to different lengths, the lengths of the upper and lower support ears can be varied.

[0022] A locking spring 9 is provided at one end of the locking ring 8. The locking spring 9 is used to push the locking ring 8 to one side, so that it can restrict the up and down movement of the connecting rod 5 (mainly to prevent it from falling off). When replacing the wheel frame, simply press the locking ring 8 to compress the locking spring 9, release the locking ring 8 from the limiting position of the connecting rod 5, and the connecting rod 5 can be detached from the sleeve. Then, the new wheel frame 6 with the connecting rod 5 can be installed.

[0023] The top sleeve 3 is composed of a left cavity 31 and a right cavity 32. It adopts a split design for easy installation of the locking ring 8. The split structure of the top sleeve 3 is secured by a square tube 2. The top sleeve 3 can be pulled out to replace its internal components. When the elasticity of the locking spring 9 deteriorates, the user can replace the spring to ensure safety.

[0024] like Figure 6 and Figure 7 As shown, the campervan of this embodiment includes: a frame body 10 and a load-bearing front wheel structure.

[0025] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics of the solutions is not described in detail here. For those skilled in the art, this utility model is obviously not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
