Technical field
The utility model relates to automobile collision preventing technical field, particularly relates to a kind of front anticollision beam of automobile.
Background technology
Front anticollision beam of automobile is mounted in the front end of the vehicle frame of automobile, when automobile generation frontal collisions time, it can be used for opposing shock, absorbed and dispersion collision energy by the conquassation of itself, it is key parts of automobile, play an important role in vehicle passive safety, therefore, the quality of front anticollision beam of automobile design will directly affect the safety of the entirety of automobile.Front anticollision beam of automobile assembly is formed primarily of collision prevention girders main body and energy-absorption box, in auto against, crumple mainly through energy-absorption box absorbs collision energy, collision can be divided into from big to small according to energy: one-level collision, secondary collision, three grades of collisions, level Four are collided, when generation three grades collision, level Four collision, when being not enough to because collision energy is less make energy-absorption box crumple, present energy-absorption box is for this kind of crash energy absorption weak effect.
Chinese patent Authorization Notice No.: CN203402106U, authorized announcement date on January 22nd, 2014, disclose a kind of front anticollision beam of automobile assembly mounting structure and automobile, wherein, front anticollision beam of automobile assembly mounting structure comprises front anticollision beam assembly and two front side members, front anticollision beam assembly comprises front anti-collision beam body, a left side for the rear surface of front anti-collision beam body, right both sides connect front anti-collision beam energy absorbing box respectively, the rear surface of two front anti-collision beam energy absorbing boxes is connected with the front surface of a front anti-collision beam adapter plate respectively, the rear surface of two front anti-collision beam adapter plates is connected with the front end of two front side members respectively.In high-speed crash, front anticollision beam assembly can effectively absorb and energy dispersive, at utmost reduces the injury to crew module.Its weak point is that existing front anticollision beam of automobile is effective for one-level, secondary crash energy absorption, and three grades, level Four collision cannot cause energy-absorption box crumple, therefore for three grades, level Four crash energy absorption weak effect.
Utility model content
The utility model, in order to solve the aforementioned problems in the prior, provide one and according to collision energy size, can adopt different energy-absorbing modes, the better multistage energy-absorption type front anticollision beam of automobile of energy-absorbing effect.
To achieve these goals, the utility model adopts following technical scheme:
A kind of multistage energy-absorption type front anticollision beam of automobile, comprise collision prevention girders body and one-level energy-absorption box, one-level energy-absorption box is vertically fixed on the two ends of anti-collision beam homonymy, also comprise secondary energy-absorption box, described one-level energy-absorption box is set in outside secondary energy-absorption box, two sides that described one-level energy-absorption box is relative are provided with some waist shaped hole A, waist shaped hole B, bolt A runs through secondary energy-absorption box from waist shaped hole A and passes through nut locking, bolt B runs through secondary energy-absorption box from waist shaped hole B and passes through nut locking, the diameter of described bolt A is greater than the diameter of bolt B, the length of waist shaped hole A is greater than the length of waist shaped hole B.
In time there is level Four collision, collision energy is consumed by the relative movement friction between one-level energy-absorption box, secondary energy-absorption box, when there is three grades of collisions, consumed by the friction force between the shearing force of bolt B and two energy-absorption boxes, when there is secondary collision, consumed by friction force between the shearing force of bolt A and two energy-absorption boxes, when there is one-level collision, one-level energy-absorption box, the crumple of secondary energy-absorption box absorb collision energy; Therefore this structure can according to collision energy size, and adopt different energy-absorbing modes, energy absorbing efficiency is good.
As preferably, the described curved structure of collision prevention girders intrinsic single, its cross section is order font.Arc can increase the bulk strength of collision prevention girders body, and order shaped sections is also to gain in strength.
As preferably, interference fit between described one-level energy-absorption box, secondary energy-absorption box, the outer end of described secondary energy-absorption box is provided with butt flange.Interference fit, when one-level energy-absorption box, the relative movement of secondary energy-absorption box, friction force is comparatively large, and energy-absorbing effect is good.
Therefore, the utility model has can be different according to collision energy, adopt different energy-absorbing mode multiple stage energy-absorbings, the better beneficial effect of energy-absorbing effect.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the connection structure schematic diagram of one-level energy-absorption box and secondary energy-absorption box.
In figure: collision prevention girders body 1 one-level energy-absorption box 2 secondary energy-absorption box 3 waist shaped hole A4 waist shaped hole B 5 bolt A 6 bolt B 7 butt flange 8.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
The multistage energy-absorption type front anticollision beam of automobile of one as shown in Figure 1, comprise collision prevention girders body 1 and one-level energy-absorption box 2, the overall curved structure of collision prevention girders body 1, its cross section is order font, one-level energy-absorption box is vertically fixed on the two ends of anti-collision beam homonymy, also comprise secondary energy-absorption box 3, one-level energy-absorption box is set in outside secondary energy-absorption box, one-level energy-absorption box 2, interference fit between secondary energy-absorption box 3, the outer end of secondary energy-absorption box is provided with butt flange 8, butt flange is connected with the front terminal bolt of the vehicle frame of automobile, as shown in Figure 2, two sides that one-level energy-absorption box 3 is relative are provided with some waist shaped hole A4, waist shaped hole B5, bolt A6 runs through secondary energy-absorption box from waist shaped hole A and passes through nut locking, bolt B 7 runs through secondary energy-absorption box from waist shaped hole B and passes through nut locking, the diameter of bolt A is greater than the diameter of bolt B, the length of waist shaped hole A is greater than the length of waist shaped hole B, bolt A, after bolt B connects, all be positioned at waist shaped hole A, the low order end of waist shaped hole B, such guarantee is when collision prevention girders body collides, one-level energy-absorption box, secondary energy-absorption box can along waist shaped hole synchronizing moving, friction energy-absorbing, the length of waist shaped hole A is greater than the length of waist shaped hole B simultaneously, ensure that the maximum moving distance of bolt A is greater than the maximum moving distance of bolt B, when colliding, the bolt B that diameter is little is first subject to shearing force and cuts off.
