Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to an electric vehicle frame rear support tube assembly and an electric vehicle. Background Art

[0002] The frame is the main structure of an electric vehicle, supporting and connecting components such as the battery, motor, and controller. It is crucial to the vehicle's stability, safety, and overall performance. Common frame structures include tubular and plate frames. The tubular frame is a common structure for electric vehicles. Made from welded steel tubes, it offers advantages such as simplicity, light weight, and high strength. The tubular frame is formed by welding steel tubes into a single structure. This design reduces weight while maintaining high strength, improving the vehicle's handling and range. Tubular frames are typically suitable for sports and high-performance electric vehicles, meeting the strength and lightweight requirements of these models. In addition to their simple structure and light weight, tubular frames also offer high strength, capable of withstanding the various forces and impacts encountered during driving, ensuring vehicle stability and safety. The support tube portion of existing electric vehicle frames is welded together from multiple sets of steel tubes and reinforcement plates. Due to manufacturing instability, the steel tubes are prone to interference or gaps between the support reinforcement plates. This also makes it difficult to maintain the correct angle between the tubes, leading to poor or even impossible welding. In addition, the existing support tubes have many welding points, and slight differences will lead to the inability to produce and the quality cannot be guaranteed, resulting in a long trial production cycle for the entire vehicle and affecting the progress of vehicle development.
