Problems solved by technology

[0004] 1. The fixed structure of the battery pack is obtained by casting. On the one hand, it increases the production cost and the yield is low. On the other hand, it has the disadvantage of being too heavy;
[0005] 2. The fixed structure of the battery pack adopts an L-shaped structure. Due to the heavy weight of the battery pack, this fixed structure is easily deformed, resulting in extremely low connection reliability.

Abstract

The present invention relates to the technical field of electric vehicles and particularly relates to a battery fixing structure, an electric vehicle chassis and an electric vehicle. The battery fixing structure comprises a pair of suspension plates extending longitudinally along a vehicle body, and a battery installation space is formed between the pair of suspension plates. Side beam receiving cavities and reinforcing member receiving cavities are formed in the suspension plates, support assemblies and a plurality of reinforcing members are formed in the reinforcing member receiving cavities, the support assemblies provide support in the suspension plates, the reinforcing members fixedly pass through the support assemblies, the reinforcing members are provided with threaded holes, and the suspension plates are provided with first through holes. The electric vehicle chassis comprises the battery fixing structure. The electric vehicle comprises the electric vehicle chassis. According to the battery fixing structure, the electric vehicle chassis and the electric vehicle, the battery fixing structure has the advantages of simple structure and easy manufacture, the production cost canbe greatly reduced, the structural strength of the suspension plates is high, the distortion and deformation are prevented, a battery module and the suspension plates are screwed together, and the connection reliability is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a battery fixing structure, an electric vehicle chassis and an electric vehicle. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Its vehicle-mounted power supply usually includes multiple batteries, and multiple batteries form a battery pack to meet the power requirements of the vehicle. [0003] However, due to the weight and volume of the battery pack composed of multiple batteries, the battery pack usually needs to be fixed under the vehicle body. The existing battery pack fixing methods have the following disadvantages: [0004] 1. The fixed structure of the battery pack is obtained by casting. On the one hand, it increases the production cost and the yield is low. On the other hand, it ha...
