Electric vehicles are becoming more and more a hot topic in the automotive field. At present, the common problem in the electric vehicle field is that the battery life of electric vehicles is limited, which restricts the promotion and application of electric vehicles. The traditional door assembly is stamped with steel plates, and the outer door panel and the inner door panel are assembled and electrophoretically painted after the edge is wrapped. The overall weight of the door is heavy, the fixed investment cost is high, and the electrophoretic painting pollution is large, which is not suitable for the green environmental protection requirements advocated by the electric vehicle industry. In order to reduce the weight of the door, the outer door panel of the door is currently also made of plastic outer panels. The plastic outer door panel and the inner door panel are mostly formed by bonding to form the door assembly, which has dimensional stability problems and is not easy to install, disassemble and repair.

[0003] For example, Chinese patent CN 219339156U discloses a composite door system, including: a composite door inner panel assembly, which is formed by injection molding a composite door inner panel substrate integral mold insert with a composite door reinforcement insert assembly; a metal main body load-bearing frame assembly, which is assembled and welded by a door hinge area sheet metal reinforcement, an outer waistline reinforcement, a door lock B-pillar side sheet metal reinforcement, a door rearview mirror triangle window area reinforcement and a door anti-collision beam; a composite door outer panel assembly, which is formed by bonding a composite door outer panel bracket and a composite door outer panel; the door outer panel assembly and the door inner panel assembly are also bonded and composited, and there is a problem of poor dimensional stability.

[0007] Further:

[0008] The outer panel reinforcement plate is a frame structure, and the vehicle door outer panel and the outer panel reinforcement plate are bonded and connected by polyurethane adhesive.

[0009] The bonding inner sides of the vehicle door outer panel and the outer panel reinforcement plate form a cavity structure, and the fasteners on the outer panel reinforcement plate are arranged corresponding to the cavity.

[0010] The edge of the door outer panel is arranged to cover the edge of the outer panel reinforcement plate.

[0011] The upper edge of the door outer panel corresponds to the window sill position and is connected by snapping with the inner panel sheet metal structure.

[0012] The lower edge of the door outer panel and the side edge corresponding to the hinge are both provided with a flange structure.

[0013] A clip is arranged at the upper edge of the door outer panel corresponding to the window sill position, and a clip groove matched with the clip is arranged on the inner panel sheet metal structure.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] The door assembly has a reasonable structural design. The plastic door outer panel and the outer panel reinforcement plate are bonded together. The outer panel reinforcement plate and the door inner panel assembly are connected by fasteners. Through the internal and external connection of the reinforcement plate, the dimensional stability can be well controlled, and the installation and disassembly are simple.
