Light-weight all-plastic tail door assembly

Abstract

The invention belongs to the technical field of plastic tail doors, and provides a light-weight all-plastic tail door assembly which comprises an inner plate, a spoiler, an outer plate, tail window glass and an air window decorating part. The inner plate, the spoiler and the outer plate are attached into a whole. The spoiler, the tail window glass and the inner plate form a sandwich type gluing structure. The side, inside a vehicle, of the inner plate is provided with a tail light installing U-shaped cavity, a left side main reinforcing beam, a right side main reinforcing beam, a left side auxiliary reinforcing beam, a right side auxiliary reinforcing beam, a door lock installing hole area, a left tail light maintaining hole area, a right tail light maintaining hole area, a left side buffer block installing position and a right side buffer block installing position. The light-weight all-plastic tail door assembly has the advantages that the quantizable data basis is provided for subsequent plastic tail door products, the scheme can be easily transplanted, the good plastic tail door mechanical performance is realized, and therefore the development difficulty and development cost ofthe plastic tail door product are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of plastic tailgates, and relates to a plastic tailgate, in particular to a lightweight all-plastic tailgate assembly. Background technique [0002] With the wave of electrification of automobiles, how to carry out lightweight design of the car itself has become an important means to improve the battery life of electric vehicles under the condition that the battery life of the existing battery is slowly improved. As an emerging lightweight technology solution, the all-plastic tailgate is favored by major OEMs because of its excellent lightweight effect. However, compared with the traditional metal tailgate, the all-plastic tailgate is made of thermoplastic materials for its inner and outer panels, and the forming method is quite different from the stamping and welding of the traditional metal tailgate. All of them are quite different from the traditional metal tailgate. In the design and development proces...

Problems solved by technology

And there are often many interfaces that overlap each other, which complicates the design of the tailgate structure. The disadvantages of the existing all-plastic tailgate are: the space required for the glue application area is large, the most shape design, the glue application track layout, and the glue application effect are all good. Restrictions, the layout of high brake lights is limited, the assembly size of the spoiler is difficult to control, and the local rigidity is difficult to meet. In addition, there are generally two solutions for the design of the inner panel of the tailgate: 1. Add a large number of ribs to the B side of the product for reinforcement; The disadvantage of this solution is that too many ribs lead to shrinkage on the surface of the product, and on the other hand, it also increases the difficulty of product demoulding; 2. Partially increase the metal inserts or composite material reinforcements for gluing and strengthening. The disadvantage of this solution is that it increases Product quantity and production cycle time, cost rise
