Description

Technical Field

[0001] This utility model relates to the technical field of chassis structure design and manufacturing of beach buggies (or all-terrain vehicles), specifically a bridge-box integrated connection mechanism for beach buggies. Background Technology

[0002] Traditional ATVs (or all-terrain vehicles) often use a large crossbeam structure to connect the front and rear axles, which has the following drawbacks:

[0003] 1. Structural redundancy: The independent crossbeam and battery box design result in component duplication, increasing the overall vehicle weight (by about 15%-20%) and affecting power efficiency and range;

[0004] 2. Complex assembly: The crossbeam and battery box need to be welded in steps, which increases the labor cost (adds 2-3 hours to the assembly time of a single unit) and is prone to positioning deviation due to welding deformation;

[0005] 3. Maintenance difficulties: When the integrated chassis is damaged, the entire chassis needs to be replaced, resulting in high repair costs. Although existing patents propose modular battery boxes, they do not solve the integration problem between the wheel assembly connectors and the load-bearing structure, and still rely on auxiliary support frames.

[0006] To address this, those skilled in the art have proposed an integrated bridge-box connection mechanism for ATVs. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model proposes an integrated bridge and box connection mechanism for beach buggies, which aims to directly form a load-bearing chassis by connecting the battery box and wheel assembly, eliminating traditional crossbeams, reducing redundant parts, and lowering weight.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An integrated bridge and box connection mechanism for a beach buggy includes a battery box and wheel assembly connectors; the front and rear ends of the battery box are respectively fixedly connected to the wheel assembly connectors, and the battery box and the front and rear wheel assembly connectors are connected to form the overall load-bearing chassis structure of the beach buggy.

[0010] Furthermore, the battery box is composed of two short side plates, two long side plates, an upper cover plate, and a lower base plate; the wheel assembly connectors are respectively fixedly connected to the sides of the short side plates, and the connecting surfaces of the two short side plates are provided with several through holes for installation and connection.

[0011] Furthermore, the wheel assembly connector includes a front connector and a rear connector, both of which are integrally formed. The front connector has a connection surface for fixed connection with the battery box, and the rear connector has a mounting surface for fixed connection with the wheel assembly.

[0012] Furthermore, the connecting surface of the wheel assembly connector is provided with a fixing hole corresponding to the position of the through hole. By passing fasteners through the through hole and the fixing hole in sequence, the wheel assembly connector and the battery box are locked in a front-to-back two-way connection.

[0013] Furthermore, the front and rear connecting surfaces of the upper cover plate and the lower base plate are provided with several through holes for installation and connection.

[0014] Furthermore, the upper and lower connecting surfaces of the wheel assembly connector are provided with fixing holes two corresponding to the positions of the through holes two. By passing fasteners through the through holes two and fixing holes two in sequence, the wheel assembly connector and the battery box are locked together in both directions.

[0015] Furthermore, the short side plate, long side plate, upper cover plate, and lower bottom plate are made of aluminum alloy.

[0016] Compared with existing technologies, this invention offers the following advantages: It provides an integrated axle-box connection mechanism for ATVs, including a battery box and wheel assembly connectors. The front and rear ends of the battery box are fixedly connected to the wheel assembly connectors, and the connection between the battery box and the front and rear wheel assembly connectors constitutes the overall load-bearing chassis structure of the ATV. The battery box and wheel assembly connectors directly form the load-bearing chassis, eliminating the traditional large crossbeam structure, reducing redundant components, and lowering the overall weight of the ATV. Simultaneously, modular connections enable rapid assembly, reducing labor time and costs, simplifying the assembly process, and achieving rapid assembly of the ATV's load-bearing chassis.

[0024] 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.

[0025] Please see Figure 1-6 This utility model provides a technical solution: an integrated bridge and box connection mechanism for ATVs, including a battery box 1 and wheel assembly connectors 2; the front and rear ends of the battery box 1 are respectively fixedly connected to the wheel assembly connectors 2, and the battery box 1 and the front and rear wheel assembly connectors 2 are connected to form the overall load-bearing chassis structure of the ATV. The battery box 1 and the wheel assembly connectors 2 directly form the load-bearing chassis, eliminating the traditional large crossbeam structure, reducing redundant parts, and lowering the overall weight of the ATV. At the same time, modular connection enables rapid assembly, reducing labor time and labor costs, simplifying the assembly process, and realizing the rapid assembly of the ATV load-bearing chassis.

[0026] Please see Figure 3-4 The battery box 1 is composed of two short side plates 10, two long side plates 11, an upper cover plate 12, and a lower base plate 13; the short side plates 10, long side plates 11, upper cover plate 12, and lower base plate 13 are made of aluminum alloy. Aluminum alloy reduces weight while being corrosion resistant, making it suitable for harsh environments such as frequent water crossings and sandstorms encountered by ATVs.

[0027] The wheel assembly connectors 2 are fixedly connected to the sides of the short side plates 10, and the connecting surfaces of the two short side plates 10 are provided with several through holes 100 for installation and connection. The battery box 1 is composed of multiple panels, which facilitates separate production and transportation, and reduces manufacturing complexity. The through holes 100 on the short side plates 10 provide precise positioning for the wheel assembly connectors 2 and avoid misalignment during installation.

[0028] Please see Figure 5 The wheel assembly connector 2 includes a front connector 20 and a rear connector 21, both of which are integrally formed. The front connector 20 has a connection surface that is fixedly connected to the battery box 1, and the rear connector 21 has a mounting surface that is fixedly connected to the wheel assembly. The front connector 20 and the rear connector 21 are integrally formed, reducing welding or splicing steps and improving structural strength; the mounting surface is directly adapted to the wheel assembly, reducing the need for secondary adjustments.

[0029] Please see Figure 4-5The connecting surface of the wheel assembly connector 2 is provided with a fixing hole 200 corresponding to the position of the through hole 100. Fasteners are used to sequentially pass through the through hole 100 and the fixing hole 200 to achieve a front-rear bidirectional locking connection between the wheel assembly connector 2 and the battery box 1. The corresponding design of the through hole 100 and the fixing hole 200, achieved through fasteners, enhances connection stability and prevents axial loosening during vehicle operation.

[0030] Please see Figure 3 , Figure 5 The upper cover plate 12 and the lower base plate 13 have several through holes 110 on their front and rear connecting surfaces for installation and connection. The upper and lower connecting surfaces of the wheel assembly connector 2 have fixing holes 210 corresponding to the positions of the through holes 110. By having fasteners pass through the through holes 110 and fixing holes 210 in sequence, the wheel assembly connector 2 and the battery box 1 are locked together vertically. The cooperation between the upper and lower through holes 110 and fixing holes 210 forms a vertical lock, which, together with the front and rear locks, constitutes a three-dimensional stable system to distribute the load-bearing stress.
