Abstract
本实用新型涉及一种车辆前碰撞横梁结构，它具有一个弧形的由内外板组成的第一横梁焊接总成，在第一横梁焊接总成的两端设有左右前碰撞盒焊接总成，前碰撞盒焊接总成由左右两个前碰撞盒、前端采用保护焊焊接的第一横梁侧锁板和后端焊接的前碰撞盒安装支架组成，前碰撞盒的前端通过焊接第一横梁侧锁板与第一横梁焊接总成连接，其后端焊接前碰撞盒安装支架，前碰撞盒安装支架与车辆纵梁通过螺栓进行连接。本实用新型将原来碰撞横梁总成同车架纵梁的焊接连接改为活动连接，解决汽车在低速碰撞发生时，不会损坏车身主体结构，便于维修更换，并通过对高速碰撞时的变形方向的设计，提高了车辆碰撞时的吸能效果。
The utility model relates to a vehicle front collision crossbeam structure, which has an arc-shaped first crossbeam welding assembly composed of inner and outer plates, and left and right front collision box welding assemblies are arranged at both ends of the first crossbeam welding assembly. The front crash box welding assembly is composed of two left and right front crash boxes, the first beam side lock plate welded by shielded welding at the front end and the front crash box mounting bracket welded at the rear end. The front end of the front crash box is welded by welding the first beam side lock plate The plate is connected with the welding assembly of the first beam, and its rear end is welded with the mounting bracket of the front crash box, and the mounting bracket of the front crash box is connected with the longitudinal beam of the vehicle through bolts. The utility model changes the welding connection between the original collision beam assembly and the frame longitudinal beam into a movable connection, which solves the problem that the main body structure of the vehicle body will not be damaged when the automobile collides at a low speed, which is convenient for maintenance and replacement, and can be used to adjust the deformation direction during high-speed collisions. The design improves the energy absorption effect when the vehicle collides.
Description
Technical field
The utility model belongs to the vehicular spare parts technical field, is specifically related to collide beam structure before a kind of vehicle.
Background technology
Auto against is recurrent traffic accident, even if all be difficult to return to original state by maintenance behind the vehicle collision, the safety of automobile low speed collision (5Km/h) is the requirement of mandatory rules of law institute, in this collision laws and regulations requirement automobile design an energy-absorbing district should be arranged, in a single day Shi Buhui damages vehicle body bumping.
Existing automobile has all designed collision crossbeam assembly, and it in case collided, when keeping in repair, tends to be corrupted to the longeron of vehicle frame with the autobody stringpiece weld together.The big cost height of Wei Xiu work capacity like this.In addition, existing collision crossbeam assembly lacks the design in energy-absorbing district, and is not strong to the protection of automobile.
Summary of the invention
The purpose of this utility model is the defective at the prior art existence, before being provided, a kind of vehicle collides beam structure, changed collide the crossbeam assembly originally as flexible connection into being welded to connect of chassis side rail, solve automobile when low speed collision takes place, can not damage main structure of vehicle body, be convenient to maintain and replace, and the design of the deformation direction by to high-speed crash the time, the energy-absorbing effect when improving vehicle collision.
The technical solution of the utility model is as follows:
Collision beam structure before the vehicle; first crossbeam of being made up of inner and outer plates that it has an arc welds assembly; be characterized in: collision box welding assembly before about the two ends of first crossbeam welding assembly are provided with; before collision box welding assembly by about collide box before two; front end adopts the first crossbeam side chain plate of protection weldering welding and the preceding collision box mounting bracket of rear end welding to form; the front end of preceding collision box is connected by welding first crossbeam side chain plate and first crossbeam welding assembly; collision box mounting bracket before the welding of its rear end, preceding collision box mounting bracket is connected by bolt with the vehicle longeron.
Further, the collision beam structure also has inside compression muscle in the design of the middle part of preceding collision box before this vehicle.
The advantage of present technique is:
1, because preceding collision crossbeam is connected with car body by the bolted connection that welds the activity of fixedly changing into, makes it when low speed collision is damaged, can discharge replacing very easily, can not damage vehicle body, have good maintainability, shorten maintenance time and reduce the dimension cost.
2, preceding collision crossbeam is a camber, when low speed collision, can absorb energy effectively, and it is simple and practical.
3, at the inside compression muscle of the middle part of preceding collision box design, when height collides, can determine deformation direction, improve the energy-absorbing effect of vehicle collision.
Description of drawings
Fig. 1 is the structural representation of collision beam structure before this vehicle;
Fig. 2 is a design-calculated compression muscle structural representation on the preceding collision box.
The specific embodiment
Referring to Fig. 1; it has first crossbeam welding assembly 1 that a camber inner and outer plates is formed to collide beam structure before this vehicle; collision box welding assembly before about the two ends of first crossbeam welding assembly are welded with; preceding collision box welding assembly by about collision box 2 before two; 3; front end adopts the first crossbeam side chain plate 4 and 5 of protection weldering welding; form with the preceding collision box mounting bracket 6 and 7 of rear end welding; before just forming vehicle, assembly that these several parts are welded into and 1 welding of first crossbeam welding assembly collide crossbeam; it is connected by bolt with the vehicle longeron with 7 by preceding collision box mounting bracket 6, promptly forms easy-to-dismount structure.Simultaneously, referring to Fig. 2, inside compression muscle 8 is arranged in the design of the position, middle part of preceding collision box 2,3.
