Abstract
The invention discloses a front anticollision beam device for a vehicle and relates to the technical field of vehicles. The front anticollision beam for the vehicle is characterized by comprising a front anticollision beam, two energy absorption boxes, mounting plates and mounting longitudinal beams, wherein the two energy absorption boxes are symmetrically arranged on the back sides of the two end parts of the front anticollision beam respectively; the mounting plates are fixedly arranged on the back end sides of the energy absorption boxes respectively; and the mounting longitudinal beams are fixedly arranged on the back sides of the mounting plates respectively. The front anticollision beam device for the vehicle has simple structure and good efficiency and effect, is convenient in use and can carry out oriented deformation after collision so as to lower damages.
Description
Technical field:
The present invention relates to automobile technical field, specifically a kind of automobile front anti-collision boom device.
Background technology:
The meaning of front and back collision prevention girders is exactly device vehicle first time bearing impact, has an important idea to be exactly that a bit stressed whole body is stressed in vehicle body passive security.The some positions being exactly plainly car body receive shock, and iff allowing this position go holding capacity, the protected effect so reached can be very poor.If when certain is a bit subject to power, allow whole skeleton structure go holding capacity, then can reduce the intensity of the power suffered by a point to greatest extent, particularly, crashproof girder steel just plays effect clearly here.
In this structure, what collision prevention girders two ends connected is the low speed energy-absorption box that yield strength is very low, is then connected on car body longeron by the form of bolt.Energy when low speed energy-absorption box can effectively absorb low speed impact when vehicle generation low speed collision by crumple, reduces impact as far as possible to the infringement of chassis runner, can reduce maintenance cost like this.The structure of existing energy-absorption box is comparatively simple, outside mostly is flush type, after being subject to nondirectional power when colliding, the crumple direction of energy-absorption box is uncontrolled, the upwards crumple of very possible energy-absorption box, thus cause collision prevention girders to be upturned stretching directly flying to automotive front, very large threat is caused to life, in prior art, the energy-absorbing effect of front bumperette is except the structure of front anti-collision beam itself and energy-absorption box effect, do not have other energy-absorbing effect, the effect of energy-absorbing is poor, impulsive force in the short time after colliding is caused greatly to increase, the damage that causes may be caused heavier.
Summary of the invention:
Technical matters to be solved by this invention is to provide a kind of structure simple, and easy to use, usefulness is effective, can directional deformation after colliding, and reduces the automobile front anti-collision boom device of infringement.
Technical matters to be solved by this invention realizes by the following technical solutions:
A kind of automobile front anti-collision boom device, it is characterized in that: comprise front anti-collision beam, energy-absorption box, adapter plate and installation longeron, described energy-absorption box is two and is symmetricly set on the both ends rearward position of front anti-collision beam respectively, described adapter plate is fixedly installed on the rear end side of energy-absorption box respectively, and described installation longeron is fixedly installed on the rearward position of adapter plate respectively.
Described front anti-collision beam camber and protruding to front side.Direct hard collision can be reduced, both sides can be transferred to by collision, be conducive to reducing damage.
Described energy-absorption box comprises outside plate and inner panel, and described outside plate is fixedly installed on two side positions of inner panel, and described outside plate is wave-shape board.In the present invention, this structure can make front anti-collision beam after colliding, and energy-absorption box more easily directedly can carry out crumple to both sides, and make front anti-collision beam be unlikely to be upturned or to fly out, after reducing basin dress, front anti-collision beam is to the installation hidden danger caused in vehicle.
Described inner panel is dull and stereotyped.Ensure that energy-absorption box after an impact can not both direction crumple up and down as much as possible.
The inside of described installation longeron is hollow, and the both sides positional symmetry installing longeron is provided with energy-absorbing groove, and the spacing between described energy-absorbing groove is thinning gradually from front to back.The present invention is except collision prevention girders and energy-absorption box have certain buffering energy-absorbing function, installation longeron in the present invention itself also has certain usefulness effect, the energy-absorbing groove installed on longeron has the ability of micro-deformation, and the spacing of front side energy-absorbing groove is narrower, then the spacing of side draught energy groove is wider, make the deformability of front side be greater than the deformability of rear side, after making the front of installing longeron suffer impulsive force, impulsive force has the effect weakened gradually under the effect in energy-absorbing hole.
Described adapter plate and installation longeron are respectively arranged with mounting hole.Fixing for installing.
The invention has the beneficial effects as follows: structure of the present invention is simple, and easy to use, usefulness is effective, can directional deformation after colliding, reduce infringement.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 1, a kind of automobile front anti-collision boom device, comprise front anti-collision beam 1, energy-absorption box 2, adapter plate 3 and longeron 4 is installed, energy-absorption box 2 is two and is symmetricly set on the both ends rearward position of front anti-collision beam 1 respectively, adapter plate 3 is fixedly installed on the rear end side of energy-absorption box 2 respectively, installs the rearward position that longeron 4 is fixedly installed on adapter plate 3 respectively.Front anti-collision beam 1 camber and protruding to front side.Energy-absorption box 2 comprises outside plate 21 and inner panel 22, and outside plate 21 is fixedly installed on two side positions of inner panel 22, and outside plate 21 is wave-shape board.Inner panel 22 is dull and stereotyped.The inside of installing longeron 4 is hollow, and the both sides positional symmetry installing longeron 4 is provided with energy-absorbing groove 5, and the spacing between energy-absorbing groove 5 is thinning gradually from front to back.Adapter plate 3 and installation longeron 4 are respectively arranged with mounting hole 6.
More than show and describe groundwork of the present invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
