Description

Technical Field

[0001] The utility model belongs to the technical field of automobile tailgates and relates to an improved bonding structure for an automobile composite material tailgate outer panel. Background Art

[0002] For example, in order to meet the demoulding direction of the inner panel and the outer panel, the current composite tailgate is usually designed with a doghouse-shaped bonding structure in the upper area of ​​the outer panel taillight slot. One side of the doghouse-shaped structure is on the back of the root of the taillight slot, and the other side is on the back of the outer panel appearance surface. The outer panel is a painted part, which is prone to appearance shrinkage defects. In addition, the doghouse-shaped bonding structure cannot be designed with a rounded corner at the root on the back side of the appearance surface, resulting in excessive glue application. Therefore, the glue may not be completely filled to the root, causing water leakage. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an improved bonding structure of an automobile composite material tailgate outer panel, which does not need to worry about appearance shrinkage and ensures uniform glue application, in view of the current status of the prior art.

[0004] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: an improved bonding structure of an automobile composite material tailgate outer panel, comprising an inner panel and an outer panel, the outer panel having a taillight groove, characterized in that the outer panel is formed with a doghouse-type bonding portion, the doghouse-type bonding portion is integrally extended upward with a rear windshield bonding portion, the inner panel has a rear windshield glass bonding surface and an inner panel bonding surface, the doghouse-type bonding portion is located on the upper area of ​​the taillight groove, one side of the doghouse-type bonding portion is bonded to the inner panel bonding surface, and the rear windshield bonding portion on the other side is bonded to the back of the rear windshield glass bonding surface.

[0005] In the above-mentioned improved bonding structure of the tailgate outer panel of an automobile composite material, arc angle transition portions are provided at the connection between the roots of both sides of the doghouse-shaped bonding portion and the inner panel.

[0006] In the above-mentioned improved bonding structure of the tailgate outer panel of a composite material for an automobile, glue is filled between the inner panel and the outer panel.

[0007] Compared with the prior art, the advantage of the utility model is that the position of the entire doghouse-type bonding is raised, one side of the doghouse-type bonding part is bonded to the inner panel bonding surface, and the rear windshield bonding part on the other side is bonded to the back of the rear windshield glass bonding surface, which can be covered by the rear windshield glass. Both sides are non-appearance areas, and there is no need to worry about appearance shrinkage. At the same time, the roots of both sides of the doghouse-type bonding part are arc-angle transition parts, which can ensure that the gap with the inner panel bonding structure is uniform, and the thickness of the bonding glue between the inner panel and the outer panel is uniform, which will not cause water leakage, thereby ensuring the overall quality of the entire tailgate. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 The invention is a schematic diagram of the improved bonding structure of the automobile composite material tailgate outer panel. DETAILED DESCRIPTION

[0009] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0010] In the description of the present invention, it is necessary to understand that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0011] In the figure, inner panel 100, outer panel 200, tail light groove 300, doghouse-shaped bonding portion 400, rear windshield bonding portion 500, rear windshield glass bonding surface 600, inner panel bonding surface 700, rear windshield glass 800, arc angle transition portion 900, and glue 1000.

[0012] like Figure 1As shown, the improved bonding structure of the composite material tailgate outer panel of the automobile comprises an inner panel 100 and an outer panel 200, wherein the outer panel 200 is provided with a taillight groove 300. In order to facilitate bonding of the inner panel 100 and the outer panel 200 and ensure a beautiful appearance, the outer panel 200 is formed with a doghouse-type bonding portion 400, wherein the doghouse-type bonding portion 400 is integrally extended upward with a rear windshield bonding portion 500, and the inner panel 100 is provided with a rear windshield glass bonding surface 600 and an inner panel bonding surface 700, wherein the doghouse-type bonding portion 400 is located on the upper area of ​​the taillight groove 300, wherein one side of the doghouse-type bonding portion 400 is bonded to the inner panel bonding surface 700, and the rear windshield bonding portion 500 on the other side is bonded to the back of the rear windshield glass bonding surface 600, The main innovation of this patent is to stick one side of the entire doghouse-type adhesive part 400 to the back of the rear windshield glass adhesive surface 600. Since the rear windshield glass 800 will be installed on the rear windshield glass adhesive surface 600, it can be covered by the rear windshield glass 800. Both sides are non-appearance areas, and there is no need to worry about appearance shrinkage. In addition, there is an arc-angle transition part 900 at the connection between the roots of both sides of the doghouse-type adhesive part 400 and the inner panel 100, and glue 1000 is filled between the inner panel 100 and the outer panel 200, which can ensure that the gap between the bonding structure with the inner panel 100 is uniform, and the thickness of the bonding glue between the inner panel 100 and the outer panel 200 is uniform, and no water leakage will occur, thereby ensuring the overall quality of the entire tailgate.

[0013] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
