Problems solved by technology

[0004] At present, battery boxes in the industry are mostly produced by aluminum alloy casting, sheet metal, and stamping. Cast aluminum parts are prone to casting defects, and the process is complicated. The product consistency of sheet metal and stamping is poor.
The above-mentioned battery boxes all have the problems of heavy structural weight, scrap rate, high cost, and poor sealing, which cannot well meet the development trend of lightweight and low-cost electric vehicles.

Abstract

The invention discloses a metal and composite material combined battery box in the technical field of automobile parts. The battery box is composed of a high-strength metal frame, an upper shell madeof a composite material, a middle shell made of a composite material, a lower shell made of a composite material, a sealing rubber layer and a sealing rubber strip. According to the structural characteristics and technical requirements of the battery box, different materials are applied to different positions of the battery box, and the advantages of the materials are brought into full play, so the production cost is reduced, the rigidity requirement of the battery box is met, meanwhile, the frame weight is reduced to the maximum extent, the local stress is dispersed, and the connection reliability is improved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a battery box combined with metal and composite materials. Background technique [0002] With the adjustment of the country's policy on the electric vehicle industry, higher requirements are put forward for the lightweight and cost of electric vehicles. As an important part of electric vehicles, the battery box requires lower manufacturing cost and a The weight is lighter, and at the same time, the structural strength and other performances of the battery box cannot be affected. [0003] The basic function of the battery box is to accommodate and protect the battery pack. The structure must ensure sufficient strength on the basis of retaining the largest accommodation space, taking into account the saving of layout space. And to meet the changing operating environment of the car, it is recommended to use a frame structure for the design of the battery box, that is, the frame ...
