Description

Technical Field

[0001] The utility model relates to the field of electric vehicles, in particular to a lightweight and high-strength electric vehicle frame. Background Art

[0002] Electric vehicles are powered by electricity and are an important means of transportation for people's daily travel. The frame of an electric vehicle is an important structure in an electric vehicle. In order to improve the endurance of an electric vehicle, a lightweight and high-strength electric vehicle frame is needed. Among them, the "high-strength lightweight frame" disclosed in the application number "CN202321257582.2" is also an increasingly mature technology. It "is fixed at the bottom of the inner wall of the support box by a carbon fiber frame and a first carbon fiber cross rod to increase its strength and support. The carbon fiber has excellent strength and rigidity and is very light. Several mounting holes are arranged on the inner wall of the support box for easy fixation with other components and batteries. The installation space is large, which improves the convenience of using the support box. The two triangular frames increase the frame The stability of the support is generally based on the principle that triangles are relatively strong. Furthermore, it can be made of polymer composite materials. The two triangular frames are fixed by connecting rods, and second carbon fiber cross bars are installed at the bottom ends of the two triangular frames. This can greatly improve the strength and durability of the frame and reduce the overall weight of the vehicle body. However, during use, this frame still has the following drawbacks: The carbon fiber cross bars, combined with the triangular frames and support frames, can indeed reduce the overall weight of the electric vehicle frame. However, the frame structure is complex, the inherent protective performance is not significant, and the high cost of carbon fiber limits its widespread use. Therefore, it is necessary to provide a frame that can reduce vehicle weight, save manufacturing costs, and improve protective effectiveness. Utility Model Content

[0003] The embodiment of the utility model provides a lightweight and high-strength electric vehicle frame, which aims to solve the problems of the existing frame having a complex overall structure, a heavy weight and insufficient protection effect.

[0004] To achieve the above-mentioned object, the utility model provides a lightweight and high-strength electric vehicle frame, comprising a frame assembly;

[0005] The frame assembly includes a main shaft, a main frame is installed at the end of the main shaft, a crossbeam is fixedly connected to the lower end of the main frame, two tail plates are fixedly connected to the side surface of the crossbeam, two support rods are fixedly connected to the front end of the main frame, a plurality of reinforcing rods are fixedly connected to the inside of the main frame, dampers are hinged between the main frame and the two tail plates, and buffer springs are sleeved on the side surfaces of the dampers.

[0006] As a preferred solution of the present invention, a plurality of first support rods are fixedly connected between the two support rods.

[0007] As a preferred solution of the present invention, a plurality of second support rods are installed on both sides of the lower end of the main frame.

[0008] As a preferred solution of the present invention, the lower end of the main frame and the upper ends of the two tail plates are fixedly connected to hinge shafts, the upper and lower ends of the damper are fixedly connected to hinge seats, and the hinge shafts and hinge seats are hinged to each other.

[0009] As a preferred solution of the present invention, the front end of the main shaft is fixedly connected with a connecting pipe.

[0010] As a preferred solution of the present invention, the main shaft, main frame, cross beam and reinforcing rod are all hollow structures.

[0011] As a preferred solution of the present invention, the main shaft, main frame, cross beam and reinforcing rod are all made of high carbon steel, and the tail plate is an I-beam.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] When the electric vehicle frame is in use, the frame structure only includes a main shaft structure made of high carbon steel, which is combined with the main frame, crossbeam and reinforcement rod. It can not only enhance its overall strength, but also has a simple structure. The above-mentioned structure made of high carbon steel can initially reduce its own weight. In addition, the first and second support rods arranged in a triangular structure can improve the overall stability of the frame and further enhance its own compressive strength. At the same time, since the main shaft, main frame, crossbeam and reinforcement rod are all hollow structures, the overall weight of the frame can be further reduced. In addition, the tail plate of the I-beam structure can enhance the compressive strength while reducing consumables. Finally, the damper and buffer spring can improve the overall seismic performance of the frame. Compared with the frame in the prior art "a high-strength lightweight frame", the present invention not only has a simple structure through the mutual cooperation of the above structures, but also greatly reduces the overall weight of the frame through the selection of materials and the hollow structure of each component. In addition, the triangular structure between the components combined with the damper and buffer spring can improve the shock absorption performance, thereby enhancing the practicality of the frame for easy promotion and use.
