Description

Technical Field

[0001] The present invention relates to the technical field of the chassis structure design and manufacturing of beach buggies (or all-terrain vehicles), and specifically to an integrated connection mechanism for the axle housing of a beach buggy. Background Art

[0002] The chassis of traditional beach buggies (or all-terrain vehicles) mostly uses a large crossbeam structure to connect the front and rear axles, and has the following defects: 1. Structural redundancy: The separate design of the independent crossbeam and the battery box results in duplicate components, increasing the weight of the whole vehicle (by about 15% - 20%), and affecting power efficiency and endurance. 2. Complex assembly: It is necessary to weld the crossbeam and the battery box step by step, with high labor cost (the assembly time per unit increases by 2 - 3 hours), and it is easy to cause positioning deviation due to welding deformation. 3. Difficult maintenance: When the integrated chassis is damaged, it needs to be replaced as a whole, with high maintenance costs. Although existing patents have proposed modular battery boxes, they have not solved the integration problem of the wheel group connectors and the load-bearing structure, and still rely on auxiliary support frames.

[0003] Therefore, technicians in this field have proposed an integrated connection mechanism for the axle housing of a beach buggy. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the present invention proposes an integrated connection mechanism for the axle housing of a beach buggy, aiming to directly form a load-bearing chassis through the battery box and the wheel group connectors, cancel the traditional crossbeam, reduce redundant components, and reduce the weight.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: An integrated connection mechanism for the axle housing of a beach buggy, comprising a battery box and wheel group connectors; the front end and the rear end of the battery box are respectively fixedly connected with the wheel group connectors, and the battery box and the wheel group connectors at the front and rear ends are connected to form the overall load-bearing chassis structure of the beach buggy.

[0006] Further, the battery box is composed of two short-side side plates, two long-side side plates, an upper cover plate and a lower bottom plate; the wheel group connectors are respectively fixedly connected to the sides of the short-side side plates, and a plurality of through holes one for installation connection are provided on the connection surfaces of the two short-side side plates.

Further, the connection surface of the wheel group connectors is provided with fixing holes one corresponding to the positions of the through holes one, and the wheel group connectors and the battery box are locked and connected in both the front and rear directions by sequentially passing fasteners through the through holes one and the fixing holes one.

[0008] Further, a number of through holes two for installation and connection are provided on the front and rear connection surfaces of the upper cover plate and the lower bottom plate.

[0009] Further, fixing holes two corresponding to the positions of the through holes two are provided on the upper and lower connection surfaces of the wheel set connecting piece, and the wheel set connecting piece and the battery box are locked and connected in both the up and down directions by sequentially passing fasteners through the through holes two and the fixing holes two.

[0010] Further, the short side side plate, the long side side plate, the upper cover plate and the lower bottom plate are made of aluminum alloy material.

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0015] Please refer to Figure 1-6 , the present invention provides a technical solution: a beach buggy bridge and box integrated connection mechanism, including a battery box 1 and a wheel group connecting member 2; the front end and the rear end of the battery box 1 are respectively fixedly connected with the wheel group connecting member 2, and the battery box 1 and the wheel group connecting members 2 at the front and rear ends are connected to form the overall load-bearing chassis structure of the beach buggy. The battery box 1 and the wheel group connecting member 2 directly form the load-bearing chassis, canceling the traditional large crossbeam structure, reducing redundant components, and reducing the overall weight of the beach buggy. At the same time, through modular connection, rapid assembly is realized, reducing working hours and labor costs, simplifying the assembly process, and realizing the rapid assembly of the beach buggy load-bearing chassis.

[0016] Please refer to Figure 3-4 , the battery box 1 is composed of two short-side side plates 10, two long-side side plates 11, an upper cover plate 12, and a lower bottom plate 13; the short-side side plates 10, long-side side plates 11, upper cover plate 12, and lower bottom plate 13 are made of aluminum alloy materials. The aluminum alloy material reduces weight while having corrosion resistance, adapting to harsh environments such as high-frequency wading and sand and dust of the beach buggy.

[0017] The wheel group connecting members 2 are respectively fixedly connected to the sides of the short-side side plates 10, and a plurality of through holes one 100 for installation connection are provided on the connecting surfaces of the two short-side side plates 10. The battery box 1 is composed of multiple panels, which is convenient for separate production and transportation, reducing manufacturing complexity. The short-side side plates 10 are provided with through holes one 100 to provide accurate positioning for the wheel group connecting members 2 and avoid installation misalignment.

[0018] Please refer to Figure 5 , the wheel group connecting member 2 includes a front connecting body 20 and a rear connecting body 21 of an integral structure. The front connecting body 20 is provided with a connecting surface fixedly connected to the battery box 1, and the rear connecting body 21 is provided with an installation surface fixedly connected to the wheel group. The front connecting body 20 and the rear connecting body 21 are integrally formed, reducing welding or splicing links and improving structural strength; the installation surface is directly adapted to the wheel group, reducing the need for secondary adjustment.

[0019] Please refer to Figure 4-5, on the connecting surface of the wheel set connecting member 2, there is a first fixing hole 200 corresponding to the position of the first through hole 100. The wheel set connecting member 2 and the battery box 1 are locked and connected in both the front and rear directions by sequentially passing fasteners through the first through hole 100 and the first fixing hole 200. The corresponding design of the first through hole 100 and the first fixing hole 200 enables two-way fixation in the front and rear directions through fasteners, enhancing the connection stability and avoiding axial loosening during vehicle driving.

[0020] Please refer to Figure 3 , Figure 5 , on the front and rear connecting surfaces of the upper cover plate 12 and the lower bottom plate 13, there are several second through holes 110 for installation and connection; on the upper and lower connecting surfaces of the wheel set connecting member 2, there are second fixing holes 210 corresponding to the positions of the second through holes 110. The wheel set connecting member 2 and the battery box 1 are locked and connected in both the upper and lower directions by sequentially passing fasteners through the second through holes 110 and the second fixing holes 210. The cooperation of the upper and lower second through holes 110 and the second fixing holes 210 forms a vertical lock, which together with the front and rear locks constitutes a three-dimensional stable system to disperse the bearing stress.
