Abstract
The utility model provides an automobile rear anti-collision beam assembly with low maintenance cost and good protecting effect. The rear anti-collision beam assembly comprises an anti-collision beam body and a mounting frame fixed on the rear anti-collision beam body, wherein, the rear anti-collision beam body is formed through cold-punching, and a crash box with a gradation section is mounted on one side of the rear anti-collision beam body in the position close to the auto body. The rear anti-collision beam body is formed by a high strength steel plate through punching, so that the weight is light, the intensity is high, and energy can be easily transmitted and absorbed in case of collision; and the rear anti-collision beam body first transmits the energy to the crash box in case of a collision,, so that the crash box is crumpled and deformed, and absorbs the collision energy; and once the collision energy is too great, the rear anti-collision beam body is deformed once again. Therefore, only the rear anti-collision beam assembly is required to be replaced in case of a low-speed collision, so as to reduce the maintenance cost; and the rear anti-collision beam body absorbs the collision energy by complete deformation in case of a high-speed collision,, so as to protect the oil tank.
Description
Technical field
The utility model belongs to field of automobile, specially refers to the rear anti-crash beam assembly of automobile.
Background technology
The anticollision beam assembly of automobile rear bumper plays when rear-end collision takes place, and the effect of protection automotive safety when vehicle generation low speed collision, can absorb collision energy as far as possible, guarantees that main structure of vehicle body is not damaged, to reduce service expenditure; When vehicle generation high-speed crash, utilize and self fully be out of shape the absorption collision energy, with protection fuel tank safety.
The anticollision beam assembly of present automobile rear bumper is mostly formed by punching press, rolling forming process manufacturing, the intensity at its each position is all bigger, and balanced, is unfavorable for absorbing collision, when bumping, can all deform even damage, cause maintenance cost to improve.
The utility model content
The purpose of this utility model is the rear anti-crash beam assembly that proposes the automobile that a kind of maintenance cost is low, protection is effective.
Rear anti-crash beam assembly of the present utility model comprises rear anti-crash beam body and the mounting bracket that is fixed on the rear anti-crash beam body, key is that described rear anti-crash beam body is cold stamping shaped, and rear anti-crash beam body also is equipped with the energy-absorbing box that the cross section is gradual change near a side of vehicle body.
Rear anti-crash beam body adopts high tensile steel plate cold stamping shaped, light weight, intensity height, collision helps transmission of energy and absorption when taking place, when bumping, rear anti-crash beam body at first transfers energy to the energy-absorbing box, impels energy-absorbing box crumple distortion, absorbs collision energy, when collision energy was excessive, rear anti-crash beam body self deformed again.Like this when low speed collision takes place; only need to change rear anti-crash beam assembly and get final product, protected the safety of main structure of vehicle body, reduced maintenance cost; and rear anti-crash beam body utilizes and self fully is out of shape the absorption collision energy when high-speed crash takes place, and has protected fuel tank safety.
In order to make energy-absorbing box generation crumple distortion better, avoid damage main structure of vehicle body when low speed collision, preferably be furnished with on the described energy-absorbing box be parallel to rear anti-crash beam body direction induce the distortion groove.
Described energy-absorbing box has two at least, and left-right symmetric is installed on the rear anti-crash beam body, and is comprehensive to the protection of main structure of vehicle body to guarantee.
The end of described energy-absorbing box is welded with adapter plate, and the profile of described adapter plate is greater than the cross section of energy-absorbing box, and adapter plate is provided with bolt hole; The position of corresponding adapter plate bolt hole is provided with corresponding through hole on the described rear anti-crash beam body.Energy-absorbing box and vehicle body main body can be installed together by bolt like this, make the fixing more firm of rear anti-crash beam assembly, when maintenance, also be convenient to dismounting.
Described energy-absorbing box is welded by upper and lower two parts, convenient production.
Rear anti-crash beam assembly of the present utility model has only energy-absorbing box generation crumple distortion and collision prevention girders body distortion when low speed collision takes place; therefore service expenditure is low; and the abundant crumple distortion of this physical efficiency of rear anti-crash beam when high-speed crash takes place; effectively absorb collision energy, thereby realize the function of protection fuel tank and main structure of vehicle body.
Description of drawings
Fig. 1 is the structural representation of rear anti-crash beam assembly of the present utility model;
Fig. 2 is the structure exploded perspective view of rear anti-crash beam assembly of the present utility model.
The specific embodiment
Describe the utility model in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
As shown in Figure 1, 2, the rear anti-crash beam assembly of present embodiment comprise rear anti-crash beam body 1 and and be fixed on two mounting brackets 2 on the rear anti-crash beam body 1, rear anti-crash beam body 1 adopts high tensile steel plate cold stamping shaped, the energy-absorbing box 3 that it is gradual change that a side of rear anti-crash beam body 1 close vehicle body also is symmetrically installed with two cross sections.
In order to make energy-absorbing box generation crumple distortion better, avoid damage main structure of vehicle body when low speed collision, be furnished with on the described energy-absorbing box 3 be parallel to rear anti-crash beam body direction induce distortion groove 33.
The end of energy-absorbing box 3 is welded with adapter plate 4, the profile of adapter plate 4 is greater than the cross section of energy-absorbing box 3, adapter plate 4 is provided with bolt hole, the position of corresponding adapter plate 4 bolts hole is provided with corresponding through hole 11 on the rear anti-crash beam body 1, energy-absorbing box 3 and vehicle body main body can be installed together by bolt like this, make the fixing more firm of rear anti-crash beam assembly, when maintenance, also be convenient to dismounting.
Energy-absorbing box 3 is welded by upper and lower two parts 31,32, convenient production.
When producing, be welded into energy-absorbing box 3 at first with rear anti-crash beam body 1 and mounting bracket 2 spot welding, and with upper and lower two parts 31,32 of energy-absorbing box 3, then with energy-absorbing box 3 and adapter plate 4 welding, at last again with rear anti-crash beam body 1 and energy-absorbing box 3 weld togethers.
