Description

Technical Field

[0001] The utility model relates to the field of automobiles, in particular to a mounting structure for a front bumper skin of an automobile. Background Art

[0002] With the development of the automobile industry, automobile bumpers, as an important safety device, have also embarked on the road of innovation. In addition to maintaining the original protection function, today's front and rear bumpers of automobiles also pursue harmony and unity with the body shape, and pursue their own lightweight and aesthetics. In order to achieve this goal, the front and rear bumpers of automobiles are usually made of plastic. Due to the material characteristics of plastic, the front and rear bumpers of plastic materials are prone to deformation during assembly, resulting in poor dimensions such as gap surface difference between the bumper and its matching related parts during loading, and obvious appearance problems, affecting the overall appearance of the car body. In particular, the sharp corner area of ​​the front bumper skin (the sharp corner area here refers to the cantilever area where the two ends of the front bumper skin meet the hood) is prone to deformation and collapse due to the lack of effective internal support, resulting in obvious appearance surface gaps between the front bumper skin and the hood in the adjacent sharp corner area, and manual debugging is required at the loading site.

[0017] 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, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more features.

[0019] See also Figure 1 As shown, an embodiment of the utility model provides a mounting structure for a front bumper skin of an automobile, comprising a front bumper skin 1 and a front center bracket 2 for supporting and fixing the front bumper skin 1, the upper edge of the front bumper skin 1 is provided with a flange 3 for connecting with the front center bracket 2, the flange 3 overlaps the front center bracket 2 and is fastened to the front center bracket 2 by bolts.

[0020] Specifically, Figure 2 As shown, the upper surface of the front center support 2 is provided with a plurality of first mounting holes 4 at intervals along its length direction, and the flange 3 is provided with a second mounting hole 5 corresponding to the first mounting hole 4, and the bolt can pass through the corresponding first mounting hole 4 and the second mounting hole 5 to fasten the flange 3 to the front center support 2. Further, the upper surface of the front center support 2 is also provided with a plurality of buckles 6 at intervals along its length direction, and the flange 3 is provided with a plurality of bayonet holes 7 for the buckles 6 to be snapped into, and the flange 3 and the front center support 2 can be first snapped and positioned by the buckles 6 and the bayonet holes 7 during assembly, and then the two can be fastened and connected by bolts. In addition, the embodiment of the utility model is also provided with a plurality of support blocks 8 at intervals along its length direction on the front side of the front center support 2 (i.e., the side facing the front protection skin 1), and the front side of the support block 8 is provided with a reinforcing rib 9 that abuts against the front protection skin 1, which can effectively support the front protection skin 1 internally.

[0021] The two ends of the upper surface of the front center support 2 are symmetrically provided with supporting ribs 10, such as Figure 3 As shown, the support rib 10 extends along the length direction of the front center support bracket 2, and the upper surface of the support rib 10 is formed with a support slope 11 inclined upward toward its outer end (i.e., the end close to the outer edge of the front center support bracket 2). Figure 4 As shown, during assembly, the support rib 10 abuts against the lower surface of the flange 3. As the bolts are tightened, the flange 3 gradually abuts against the upper surface of the support rib 10. The sharp corner area ( Figure 2 , Figure 4 B in the figure) can be slightly tilted up under the action of the supporting slope 11, thereby reducing the appearance surface gap between the sharp corner area and the hood, ensuring a good appearance effect.

[0022] Furthermore, in order to ensure the supporting effect of the supporting ribs 10, the embodiment of the utility model is provided with two supporting ribs 10 at both ends of the upper surface of the front center bracket 2.
