Description

Side support structure of automobile front bumper
Technical Field
The invention relates to an automobile body, in particular to an automobile front bumper side bracket structure.
Background
The vehicle needs to be repaired before leaving a factory, and a bumper needs to be disassembled; in the process of disassembly, the flanging of the bumper is easy to break, so that the bumper is scrapped. When the vehicle is used by a customer, due to a slight accident or collision, individual parts of the bumper need to be replaced, and the bumper also needs to be detached at the moment. During the disassembly process, the flanging of the bumper is easy to break, and customers complain about damage to parts during the disassembly process of the 4s shop. If the bumper with the broken flanging is arranged on the original vehicle, the gap between the bumper and the vehicle body can be increased, the appearance is influenced, and abnormal sound can be seriously caused. Therefore, an improvement of the existing automobile front bumper mounting structure is urgently required.
CN 213413716U discloses a "front bumper side bracket", which comprises a bracket body, wherein the front surface of the bracket body is provided with a plurality of main mounting holes, and the bottom surface is provided with an auxiliary mounting hole; and a clamping hook matched with the front bumper side wall mounting clamping groove is arranged on the side surface of the bracket body. Still disclose "an mounting structure of front bumper and automobile body", including front bumper, front fender welt and front bumper collateral branch frame, the front fender welt is located the front fender below, the vertical rigid coupling of front bumper collateral branch frame is in front bumper side reason with the turn-ups's of front fender cooperation position department, front bumper collateral branch frame bottom surface with front fender welt fixed connection. The automobile shock absorber is simple in structure, stable in installation, not prone to sliding and capable of enduring vehicle shock.
CN 205601766U discloses a "side bracket of front bumper" for fixing the side wall of bumper on the fender. Support itself is fixed on the turn-ups that has first turn-ups and second, characterized by: two mounting holes are arranged in the X direction of the bracket, and one mounting hole is arranged in the Y direction; a clamping hook matched with the mounting clamping groove of the side wall of the front bumper is arranged in the X direction; for convenience in installation, the X-direction installation hole is a circular first installation hole and an oblong second installation hole, and the circle center of the first installation hole and the long axis of the second installation hole are on the same straight line; the support is fixed on the flange of the fender through the matching of a bolt and a rivet nut on the flange of the fender, wherein the X-direction mounting hole corresponds to the first flange, and the Y-direction mounting hole corresponds to the second flange. The support can be more stably installed, is not easy to slide, can bear the vibration of a vehicle, and keeps the appearance neat.
The technical solutions disclosed in the above two patent documents are a useful attempt in the technical field. But the problem that the existing automobile front bumper exists in the disassembling process is not solved.
