Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, and more specifically, to an automobile rear floor reinforcement beam reinforcement component assembly. Background Art
[0002] With the continuous development of the automobile industry, product competition is becoming increasingly fierce, and people's requirements for automobile safety are getting higher and higher. In the process of rear-end collision, due to the high collision speed, the rear floor rigidity is relatively weak. During the collision, the seat and the floor installation are prone to deformation, causing the seat to flip over, the passenger's torso to move forward as a whole, causing injuries to the passenger's head and chest. Therefore, strengthening the floor strength is an urgent matter.
[0003] For example, a car rear floor reinforcement beam with publication number CN205149998U includes a reinforcement beam body formed by a bottom wall and two side walls, which has a U-shaped cross-section and an overall arc shape, and outward flanges are provided on both sides of the opening of the reinforcement beam body, and a nut and four positioning holes are provided in the middle position of the bottom wall of the reinforcement beam body, and the positioning holes are symmetrically arranged on the left and right sides of the nut in pairs; the reinforcement beam can be used to strengthen the strength of the rear floor, prevent the seat and the floor from flipping over in a collision, and improve the safety performance. It has the advantages of reasonable structural design, good strength, convenient positioning and convenient installation.
[0004] However, based on the working principle proposed in the above patent, the applicant believes that although the above device can be installed and positioned conveniently to a certain extent, in actual use, the rear floor reinforcement beam bears the main vibration impact and collision impact during the use of the car. In the event of a rear-end collision, the impact force is large, which will cause great harm to the user. The above device lacks effective buffering and shock absorption capabilities and there are certain safety hazards when used.
[0005] Therefore, in view of the above problems, an automobile rear floor reinforcement beam reinforcement assembly is proposed. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] 1. The utility model provides an outer beam frame as the main structure of the whole, so that the strength of the whole assembly is greatly improved. The reinforcement block is provided to provide a site for the installation of the abutment plate. After the installation of the whole device is completed, the abutment plate is located at the rearmost of the rear of the vehicle. When a rear-end collision occurs, the abutment plate is the primary collision target and can absorb the vibration impact generated by the collision in the first time.
