[0024] The following is combined with Figure 1-2 The utility model is described in further detail.

[0025] The embodiment of the utility model discloses an electric all-terrain vehicle frame.

[0026] Reference Figure 1 、 Figure 2An electric all-terrain vehicle frame includes a frame body 1, on which a rear sub-frame 8 is arranged, and the rear sub-frame 8 includes a left rear sub-frame 8 and a right rear sub-frame 8. The frame body 1 also includes a rear lifting bar 9 and a frame cross beam 10. Sub-frame mounting parts 11 are provided on both sides of the frame cross beam 10. The left rear sub-frame 8 and the right rear sub-frame 8 are respectively arranged on the left and right sides of the sub-frame mounting part 11. The left rear sub-frame 8 and the right rear sub-frame 8 are respectively fixedly connected to the rear lifting bar 9 and the frame cross beam 10 to form a fixed frame, so that the electric all-terrain vehicle frame has a strong carrying capacity, and the lifting bar can smoothly transmit the force (XYZ direction) to the frame body 1 after being subjected to force, and has good anti-collision performance; the tail box 19 is very convenient to disassemble and assemble.

[0027] In this embodiment, the vehicle frame 1 utilizes a conventional all-terrain vehicle frame, comprising a rear lift bar 9 and a frame cross member 10. In this embodiment, the frame cross member 10 includes a shock-absorbing mounting portion 12 and a trunk positioning mounting portion 13, integrating shock-absorbing and subframe mounting, achieving a high level of integration and conserving space. Specifically, the shock-absorbing mounting portion 12 and trunk positioning mounting portion 13 are formed by openings in the frame cross member 10 and secured by bolts. Two trunk mounting portions 19 and two shock-absorbing mounting portions 12 are provided, each located inside the two shock-absorbing mounting portions 12.

[0028] In this embodiment, the rear subframe 8 includes a left rear subframe 8 and a right rear subframe 8. A subframe mounting portion 11 is provided on both sides of the frame crossbeam 10. The left rear subframe 8 and the right rear subframe 8 are respectively arranged on the left and right sides of the subframe mounting portion 11. The left rear subframe 8 and the right rear subframe 8 are respectively fixedly connected to the rear lift bar 9 and the frame crossbeam 10 to form a fixed frame 1. The rear subframe 8 has a rear rack mounting portion 18. The rear subframe 8 forms a stable frame with the rear lift bar 9 and the frame crossbeam 10, and the tail box 19 is very convenient to assemble and disassemble (assembly order: frame body 1 → left rear subframe 8 / right rear subframe 8 → tail box 19 → rear lift bar 9). With the above structure, the fixed frame 1 can effectively improve the carrying capacity of the rear rack, improve the rear end anti-collision performance, increase the space of the tail box 19, and improve practicality.

[0029] In this embodiment, the mounting portion of the rear subframe 8 is located on the outer end surface of the frame cross member 10 , which can maximize the space of the trunk 19 and provide a large space.

[0030] In this embodiment, the bottom of the battery mounting portion is hollowed out, and the outer contour of the battery mounting portion is larger than the outer contour of the battery 5, so that the battery can be installed from bottom to top, which is convenient for assembly. The battery and the entire vehicle can be transported separately, greatly reducing transportation costs.

[0031] In this embodiment, the frame body 1 is provided with an outwardly bent portion, which forms the battery mounting portion. The provision of the bent portion can increase the size of the battery mounting portion, thereby accommodating larger batteries and improving applicability. Specifically, the frame body 1 also includes an upper beam and a lower beam. The upper beam is connected to the top of the mounting frame 2, and the lower beam is connected to the bottom of the mounting frame 2. The bent portion is provided on the lower beam, and the lower beam is located at the battery mounting position and is bent outward to form the battery mounting portion.

[0032] In this embodiment, the frame body 1 is provided with an upper sheet metal part and a lower sheet metal part. The upper sheet metal part and the lower sheet metal part are formed by bending the sheet metal into one piece. The upper sheet metal part and the lower sheet metal part are special-shaped structures. The openings of the upper sheet metal part and the lower sheet metal part are buckled together to form a battery 5 support frame with a closed structure. The upper sheet metal part and the lower sheet metal part are buckled together to form a closed structure. As a part of the frame body, it has high rigidity and strength. The structure integrates the power battery installation function, has good sheet metal forming consistency, high positioning accuracy, and the battery can be installed from bottom to top, which is convenient to assemble.

[0033] In this embodiment, a mounting bracket 2 is fixedly mounted on the vehicle frame body 1. Mounting bracket 2 is provided on the vehicle frame body 1 and includes a rear suspension arm mounting portion 3 and a rear stabilizer bar mounting portion 4. Mounting bracket 2, constructed from a single sheet metal component of the vehicle frame, integrates the mounting functions of the upper and lower rear suspension arms and stabilizer bar. This provides a high level of functional integration and highly accurate mounting point positioning, improving the accuracy and consistency of suspension installation positioning, simplifying the manufacturing process, and achieving a certain degree of lightweighting.

[0034] Furthermore, mounting bracket 2 is formed from a single piece of sheet metal (in other embodiments, multiple pieces of sheet metal may be joined together). Two mounting brackets 2 are provided, one on each side of the vehicle frame 1. The rear suspension arm mounting portion 3, comprised of an upper and lower rear suspension arm mounting portion, is a single sheet metal component of the vehicle frame. Mounting bracket 2 integrates the mounting functions of the upper and lower rear suspension arms and stabilizer bar, resulting in a high level of functional integration and precise mounting point positioning. By replacing the conventional "tube and lug assembly welding" method with a single piece of sheet metal, the accuracy and consistency of suspension mounting and positioning are improved, while simplifying the manufacturing process and achieving a certain degree of lightweighting.

[0035] In this embodiment, the upper sheet metal component has an approximately M-shaped longitudinal cross-section, with a support plate integrally formed at one end of the M-shape. The support plate and the vertical plate of the M-shape are connected to form an L-shape, while the lower sheet metal component has an approximately C-shaped longitudinal cross-section. The support frame for battery 5 includes a battery mounting portion. Specifically, the battery mounting portion comprises a threaded post 7 installed in a hole in the upper sheet metal component. The upper and lower sheet metal components are fastened together to form a closed structure, which serves as part of the vehicle frame 1 and has high rigidity and strength. This structure integrates the power battery 5 mounting function, achieves consistent sheet metal forming, and achieves high positioning accuracy. The power battery 5 can be installed from the bottom up, making assembly convenient. Furthermore, the power battery 5 and the vehicle can be transported separately, significantly reducing transportation costs and reducing weight.

[0036] In other embodiments, the mounting bracket 2 may be connected to the vehicle frame body 1 by a fixed method such as steel plate welding or riveting.

[0037] The frame body 1 is provided with a front subframe, which includes a connecting tube 14 fixed to the frame body 1 and a left transverse tube 15 and a right transverse tube 16 fixed to the connecting tube 14. The left transverse tube 15 and the right transverse tube 16 are respectively provided on the left and right sides of the frame body 1. A fixed frame 2 is formed between the left transverse tube 15, the right transverse tube 16, the connecting tube 14 and the frame body 1. The fixed frame 2 has a receiving cavity for accommodating an electrical box. The connecting tube 14 has a front rack mounting portion 17. The longitudinal section of the connecting tube 14 is approximately U-shaped. The two ends of the connecting tube 14 form the front rack mounting portion 17. The frame body 1 also has two front rack mounting portions 17. The four front rack mounting portions 17 of the frame body 1 and the connecting tube 14 together provide mounting points for the front rack. The internal space formed by the fixed frame 2 is large, which improves the load-bearing capacity of the front rack, improves the front anti-collision performance, and increases the space for the electrical box. In this embodiment, the left cross tube 15, the right cross tube 16, and the connecting tube 14 are welded together to form a stable fixed frame 2 with the frame body 1. The structure is simple and the load-bearing capacity is strong. When the bumper is subjected to force (in any XYZ direction), the force can be smoothly transmitted to the frame body 1, and the anti-collision performance is good.

[0038] A pedal bracket 6 is provided on the frame body 1. The frame body 1 has two frame risers, and the frame risers are provided with support ears. The pedal bracket 6 is fixedly connected to the support ears. The pedal bracket 6 is located on the left and right sides of the frame body 1, respectively corresponding to the left auxiliary foot pedal and the right auxiliary foot pedal, so that the left auxiliary foot pedal and the right auxiliary foot pedal bracket 6 are integrated into one, with a simple structure. In this embodiment, there are only two mounting points between the frame and the frame, and the assembly is simple. The provision of the support ears widens the mounting plane of the pedal bracket 6 and the frame body 1. When the auxiliary foot pedal is subjected to vertical force, the strength still meets the requirements, the number of fasteners is reduced, and the assembly is simplified.

[0039] The utility model integrates the subframe mounting portion 11 on the end face of the crossbeam, and integrates the tail box 19 mounting portion and the shock-absorbing mounting portion 12 on the side face of the crossbeam, thereby improving the functionality of the frame crossbeam 10, reducing the number of fasteners, and simplifying assembly.

[0040] The present invention also provides an electric all-terrain vehicle comprising the above-mentioned electric all-terrain vehicle frame. Since the electric all-terrain vehicle adopts all of the above-mentioned technical solutions, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, has a high degree of integration, simplifies the manufacturing process, reduces the number of fasteners, and simplifies assembly.

[0041] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. The above is only a preferred implementation method of the present invention. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without improvement, should be regarded as the scope of protection of the present utility model.
