Description

Technical Field

[0001] The invention relates to the technical field of automobile design, and in particular to a mounting bracket of a bumper and an automobile. Background Art

[0002] At present, the competition in the automobile industry is becoming increasingly fierce. Consumers not only require cars to have excellent mechanical properties, but also require them to have beautiful shapes and good comfort. The matching effect of the car's bumper and adjacent parts directly affects the overall effect of the car's appearance and has attracted the attention of consumers. Therefore, automobile manufacturers have high requirements for the matching of the car bumper and its adjacent parts. The bumper and fender are adjacent, and the matching and fixing of the two must be firm and reliable, otherwise it will affect the matching quality of the bumper and fender.

[0003] In the related art, the mounting bracket is fixed on the folded edge of the fender side, and the bumper bracket is provided with a card with a protrusion on the side close to the fender body. The card is connected to the bumper flange by the protrusion to fix and constrain the bumper. During the installation process, in order for the bumper to smoothly enter the assembly position, the bumper is assembled perpendicular to the direction of the mounting bracket. During the assembly process, the protrusion on the card is squeezed and deformed by the bumper flange until the bumper reaches the assembly position. The protrusion on the card pops up and enters the bumper flange mounting hole position, the card loses the squeeze, and the protrusion pops up and enters the mounting hole to form an assembly constraint. However, the applicant found that in order to ensure that the bumper can be assembled smoothly during use, the rigidity of the card cannot be too large to avoid being unable to be squeezed and causing excessive assembly force. However, if the rigidity of the card is too small, the bumper will have a pull-out force, and the bumper flange will squeeze the card in the opposite direction, and the bumper will easily fall out. Therefore, the design problem of the bumper mounting bracket has become a difficult problem that practitioners need to solve urgently. Summary of the invention

[0032] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings. Figure 1 , Figure 2 and Figure 5 As shown, the present application provides a mounting bracket for a car bumper, which comprises: a bracket body 1 and a slide bar 2; wherein,
