Automobile door framework structure

Abstract

The invention provides an automobile door framework structure which comprises a door lower portion framework and a window frame structure connected to the lower portion framework. The lower portion framework comprises a lower door framework, the front end of the lower door framework is connected to the lower end of a front door framework, the upper end of the front door framework is connected with an outer door window beam, a door outside handle reinforcing plate and a door lock installation plate are arranged under the outer door window beam, and he lower door framework, the front door framework and the outer door window beam are all of a hollow aluminum alloy profile structure. The automobile door framework structure is simple in structure, convenient to produce and manufacture and low in cost; a door assembly can be formed only by installing a plastic outer covering part on the door framework, a door model is conveniently replaced, and the adjustability and the plasticity are high; the light weight requirement of an electric car can be met, the endurance mileage of the electric car can be lengthened, the structural stability is good, and a good application prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of new energy automobiles, and more specifically relates to an automobile door frame structure. Background technique [0002] As a new energy vehicle, electric vehicles have the advantages of energy saving and environmental protection. Electric vehicles are becoming more and more research hotspots in the automotive field. At present, the common problem in the field of electric vehicles is that the battery life of electric vehicles is limited, which limits the popularization and application of electric vehicles. [0003] Most of the car doors used in existing electric vehicles are steel stamping parts, which have a single structure. To change the shape, they must be replaced as a whole. The production, assembly and maintenance costs of parts are relatively high, which is not conducive to cost reduction and cannot meet the requirements of energy conservation and environmental protection.
