Abstract
The utility model relates to a vehicle front collision beam structure, which is provided with an arc-shaped first beam welded assembly composed of an inner plate and an outer plate. Both ends of the first beam welded assembly are provided with a left and a right front collision box welded assemblies. Each of the front collision box welded assembly is composed of a left and a right front collision boxes, a first beam side locking plate, the front end of which is welded by a protecting welder and a front collision box installation bracket welded on the back end of the first beam side locking plate. The front end of the front collision box is connected with the first beam welded assembly by welding the first beam side locking plate, and the back end of the front collision box is connected with the front collision box installation bracket. The front collision box installation bracket is connected with a vehicle longitudinal beam through a screw bolt. The utility model changes the welded connection between an original collision beam assembly and a vehicle frame longitudinal beam into a moving connection. The utility model solves the problem of the damage of the main body structure of a vehicle body when a vehicle collides at a low speed and has the advantage of convenient maintenance and replacement. An energy absorption effect is enhanced during vehicle collision through the design of a deformation direction during high speed collision.
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.
Claims (2)
1, collision beam structure before the vehicle; it has first crossbeam welding assembly (1) of being made up of inner and outer plates; it is characterized in that: first crossbeam welding assembly (1) is arc; collision box welding assembly before about the two ends of first crossbeam welding assembly (1) have; before collision box welding assembly by about collide box (2,3), front end before two and adopt first crossbeam side chain plate (4,5) of protection weldering welding and the preceding collision box mounting bracket (6,7) that welds the rear end to form, preceding collision box mounting bracket (6,7) is connected by bolt with the vehicle longeron.
2, collision beam structure before the vehicle according to claim 1 is characterized in that: in the design of the middle part of preceding collision box (2,3) inside compression muscle (8) is arranged.
