[0002] The headlight guard plate is made of hard glue and soft glue. Due to the limitations of the guard plate material (usually PP-T20+TPV or ABS+TPE) and structure, the guard plate is usually deformed greatly. The guard plate and the body sheet metal need to fit with zero gap. After the guard plate is deformed, the zero gap fitting requirement cannot be met, which affects the lighting effect and life of the headlight. Utility Model Content

[0003] In order to solve the above problems existing in the prior art, the utility model provides a pre-deformation structure for optimizing the matching between the guard plate and the body sheet metal, and solves the poor matching problem caused by the deformation of the guard plate by optimizing the pre-deformation structure of the guard plate.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pre-deformation structure for optimizing the matching of a guard plate with a vehicle body sheet metal, comprising a guard plate, an opening at the bottom of the guard plate, the guard plate comprising a guard plate body and soft glue, the soft glue being located on the guard plate body, the soft glue comprising pre-deformed soft glue and the pre-deformed soft glue being located at the bottom opening of the guard plate body, the pre-deformed soft glue being located on the left and right sides and the upper side of the guard plate body, the pre-deformed soft glue and the bottom opening of the guard plate body being inclined outward, and the pre-deformed soft glue and the soft glue at the bottom opening of the guard plate body being connected with each other with rounded corners.

[0005] Furthermore, the pre-deformed soft rubber is inclined outward at an angle m, and the bottom opening of the guard plate body is inclined outward at an angle n, where m<n.

[0006] Furthermore, the outward inclination angle m of the pre-deformed soft rubber is 10° smaller than the outward inclination angle n of the bottom opening of the guard plate body.

[0007] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure, optimizes the guard plate structure, and designs a pre-deformed soft rubber structure, so that the guard plate can meet the requirement of zero fit with the body sheet metal even when deformed.

[0012] 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 of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0013] The material of the guard plate 1 on the headlight is usually PP-T20+TPV or ABS+TPE, which usually has a large deformation. After the deformation, the guard plate 1 cannot achieve a zero gap fit with the body sheet metal, which does not meet the requirements.

[0014] See also Figure 1-3 The technical solution provided by the utility model is: a pre-deformed structure for optimizing the matching of the guard plate with the body sheet metal, including a guard plate 1, the bottom of the guard plate 1 is open, the guard plate 1 includes a guard plate body 2 and a soft glue 3, the soft glue 3 is located on the guard plate body 2, the soft glue 3 is spliced ​​on the guard plate body 2 according to the surface shape of the guard plate body 2, and the area of ​​the soft glue 3 is larger than the area of ​​the guard plate body 2, the soft glue 3 includes a pre-deformed soft glue 4, and the pre-deformed soft glue 4 is located at the bottom opening of the guard plate body 2, the part of the soft glue 3 that is larger than the area of ​​the guard plate body 2 is the pre-deformed soft glue 4 part, the guard The pre-deformed soft glue 4 on the plate 1 is bonded to the body sheet metal, and the pre-deformed soft glue 4 is located on the left and right sides and the upper side of the guard plate body 2. The pre-deformed soft glue 4 and the bottom opening of the guard plate body 2 are both inclined outward, but the inclination direction of the pre-deformed soft glue 4 is based on the outward inclination of the bottom opening of the guard plate body 2 and is inclined toward the inside of the bottom opening of the guard plate body 2, thus forming a pre-deformed structure. The pre-deformed soft glue 4 is connected to the soft glue 3 at the bottom opening of the guard plate body 2 with a rounded corner, so that the guard plate 1 is easy to fit with the body sheet metal, and the overall length of the guard plate 1 is also guaranteed to remain unchanged; Figure 4 When the guard plate 1 is fitted with the body sheet metal, due to the pre-deformation structure designed in the utility model at the pre-deformation soft glue 4, when the guard plate 1 is not deformed, the pre-deformation soft glue 4 and the body sheet metal are in an interference state, but during assembly, due to the deformation of the guard plate 1, the pre-deformation soft glue 4 and the body sheet metal are in zero fit.

[0015] Specifically, the outward inclination angle of the pre-deformed soft glue 4 is m, and the outward inclination angle of the bottom opening of the guard plate body 2 is n, m<n, but the original soft glue 3 at the bottom opening of the guard plate body 2 has the same inclination angle as the guard plate body 2, but when the guard plate 1 is deformed, the guard plate 1 and the body sheet metal cannot meet the requirement of zero fit. Therefore, the utility model sets the outward inclination angle of the pre-deformed soft glue 4 to be smaller than the outward inclination angle of the bottom opening of the guard plate body 2.

[0016] Specifically, the outward inclination angle m of the pre-deformed soft rubber 4 is 10° smaller than the outward inclination angle n of the bottom opening of the guard plate body 2 .

[0017] The utility model rotates the pre-deformed soft glue 4 at the bottom opening of the guard plate body 2 by 10° to the inside of the bottom opening of the guard plate body 2 with the inclination angle of the bottom opening of the guard plate body 2 as the boundary, and then connects the pre-deformed soft glue 4 with the rounded corner of the soft glue 3 at the bottom opening of the guard plate body 2, and ensures that the pre-deformed guard plate 1 is consistent with the original length. When the guard plate 1 is fitted with the body sheet metal, due to the deformation of the guard plate 1, the pre-deformed soft glue 4 on the guard plate 1 is zero fit with the body sheet metal.

[0018] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
