Description

Technical Field

[0001] The utility model relates to the technical field of vehicle frame assemblies, and in particular to a lightweight vehicle frame assembly for a new energy electric vehicle. Background Art

[0002] The frame is a framework structure that spans the front and rear axles of the car, commonly known as the beam. It is the base of the car and is generally composed of two longitudinal beams and several cross beams. It is supported on the wheels via the suspension device, the front axle and the rear axle. The frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels. The function of the frame is to support and connect the various assemblies of the car, keep the assemblies in a relatively correct position, and withstand various loads inside and outside the car.

[0003] At present, when adopting lightweight structural design, automobile frame assemblies on the market usually achieve the purpose by reducing the use of materials. To a certain extent, this will lead to insufficient structural strength and rigidity of the frame. At the same time, the Chinese utility model with authorization announcement number CN212738278U discloses a new energy frame assembly. When in use, the device uses L-shaped blocks, limit grooves, limit plates and limit springs to position and limit the installation of the reinforcement component plate frame. However, in specific use, there are certain defects in limiting the reinforcement component frame through the reaction force of spring compression. Long-term use will cause fatigue of the spring, which will affect its elasticity and limiting effect, and may eventually cause the spring to fail and be unable to effectively provide reaction force for limiting. Therefore, it is necessary to redesign a lightweight frame assembly for new energy electric vehicles in response to the above problems. Utility Model Content
