Compared with the prior art, the front anti-collision beam assembly has the advantages that the nut box is arranged on the energy absorption box, positions of the nuts in the nut box are adjustable, and the positions of the nuts can be adjusted at any time as required in an installation process of the front anti-collision beam assembly, so that the connection with a frame can be completed, both the installation and the disassembly of the front anti-collision beam assembly can be facilitated.
Description
Technical field
The present invention relates to automotive technology, specifically, the present invention relates to a kind of front anticollision beam of automobile assembly.
Background technology
Front anticollision beam of automobile assembly is a key components and parts of automobile, in automotive safety index, play the part of an important role, the quality of front anticollision beam assembly design directly affects the safety performance of car load, in low speed collision accident, front anticollision beam assembly can absorb energy completely, protect important and expensive parts to be without prejudice, reduce property damage; In high-speed crash, front anticollision beam assembly will absorb and energy dispersive, the injury of the minimizing of maximum degree to crew module.
Current most automobile front anti-collision beam assembly is due to the reason of the aspects such as material or structure, front anti-collision beam assembly often can not meet Collision test requirement, energy-absorbing effect is bad, and due to the habitual fixedly welded nut assembling of front anti-collision beam assembly, is unfavorable for Assembly &Disassembly.
Summary of the invention
The invention provides a kind of front anticollision beam of automobile assembly, object is to be easy for installation and removal.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of front anticollision beam of automobile assembly, comprise collision prevention girders body and energy-absorption box, and energy-absorption box is provided with the nut box of the adjustable nut of embedded position.
Described nut box comprises the box body of rectangle, and the surface of box body is provided with the elongated hole running through, and described nut is placed in the cavity in box body, and the tapped bore of nut is positioned at the region of elongated hole, and on box body, at least three sides are provided with flange.
Described energy-absorption box is provided with two nut boxes.
The hollow structure that described collision prevention girders body is rectangle for the cross section that formed by outside plate and inner plate welding.
Described collision prevention girders body adopts the high tensile steel plate that phosphorates to make.
The present invention adopts technique scheme, compared with prior art, this front anticollision beam assembly by arranging nut box on energy-absorption box, nut location in nut box is adjustable, setting nut position at any time as required in front anticollision beam assembly process is installed, to complete and being connected of vehicle frame, thereby can facilitate the installation of front anticollision beam assembly, equally also facilitate the dismounting of front anticollision beam assembly.

Fig. 4 is B-B cutaway view in Fig. 1;
Mark in above-mentioned figure is: 1, collision prevention girders body; 2, energy-absorption box; 3, nut box; 31, box body; 32, nut; 33, elongated hole; 34, flange.
The specific embodiment
As shown in Figures 1 to 4, a kind of front anticollision beam of automobile assembly of the present invention, what comprise that collision prevention girders body 1 and 2, two energy-absorption boxes 2 of two energy-absorption boxes parallel is fixedly mounted on collision prevention girders body 1 respectively the position near two ends.Energy-absorption box 2 is provided with nut box 3, in nut box 3, be built-in with the nut 32 of position-adjustable, for being connected with the bolt of vehicle frame junction, guaranteeing under the prerequisite of front anticollision beam assembly performance intensity, due to nut 32 position-adjustable in nut box 3, when this front anticollision beam assembly is installed, only need setting nut 32 that it is alignd with the bolt on vehicle frame, easy for installation simple, equally also can facilitate the dismounting of front anticollision beam assembly.
Specifically, nut box 3 comprises the box body 31 of rectangle, the bottom opening of box body 31, the top surface of box body 31 is provided with the elongated hole 33 that is through to box body 31 inside, elongated hole 33 extends along the length direction of energy-absorption box 2, nut 32 is the cavity in bottom opening is positioned over box body 31, and the tapped bore of nut 32 will be positioned at the region of elongated hole 33, thereby the bolt on vehicle frame can insert in tapped bore and be connected with nut 32 through elongated hole 33 all the time.
On three sides of box body 31, be provided with flange 34, flange 34 is to start to stretch out toward the outer side from the bottom of box body 31, nut box 3 is weldingly fixed on the upper surface of energy-absorption box 2 by these flange 34, close bottom opening, thereby nut 32 is limited in the cavity of box body 31.
On two energy-absorption boxes 2, be respectively provided with two nut boxes 3, respectively energy-absorption box 2 for the end that is connected with chassis runner with near the position at middle part.
Because nut 32 is born the connection of front anticollision beam assembly and vehicle frame, so its hardness and load-carrying capacity have strict demand, and nut 32 needs tempered, its tempered sorbite Vickers hardness: 272-353HV; Guarantee load: under the effect of 60300N power, keep 15S, screw thread is without extremely, and can screw out with hand or by torque spanner, but must not surpass half button.
The structure of front anticollision beam assembly and material can be related to its final performance.And because front anticollision beam assembly is in the special role of car load, structurally, the hollow structure that collision prevention girders body 1 has adopted suspension welding gun spot welding blanked part outside plate and inner panel to form, as shown in Figure 3, the cross-sectional plane of collision prevention girders body 1 is rectangle, what collision prevention girders body 1 two ends connected is the energy-absorption box 2 that yield strength is lower, and as shown in Figure 4, the cross-sectional plane of energy-absorption box 2 is also rectangle.Can not be too large as the strength of material of making collision prevention girders body 1, can not be too little, so the choice for use high tensile steel plate (B250P1, B210P1 etc.) that phosphorates, existing higher intensity has again good toughness.So the collision prevention girders body 1 of special construction and material can absorb in a large number decomposition Impact energy when vehicle high-speed collides, and energy-absorbing effect is good, can farthest reduce the damage of clashing into vehicle body.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
