Abstract

The utility model relates to a shock-absorber upper bracket. The shock-absorber upper bracket comprises a bottom plate, a left vertical edge and a right vertical edge, a round hole A, a round hole B and a plurality of round holes C, wherein the left vertical edge and the right vertical edge are formed by bending relatively to the bottom plate; the round hole A and the round hole B are respectively arranged at the upper ends of the left vertical edge and the right vertical edge; the plurality of round holes C are arranged on the bottom plates; the left vertical edge and the right vertical edge are obliquely arranged relatively to the bottom in a splayed manner, and an opening at the upper end is smaller than that at the lower end; and the round hole A and the round hole B are coaxial. The shock-absorber upper bracket has the advantages that the shock absorber bracket is fixed on a frame by utilizing a bolt B through the plurality of round holes C on the bottom plate, a bolt A penetrates through the coaxial round hole A, a front shock absorber and the round hole B, and then the front shock absorber can be fixed by utilizing a nut. The left vertical edge and the right vertical edge are formed by stamping, and compared with the welding mode, not only is the strength of the bracket improved, but also the manufacturing procedure is reduced and the weight is reduced.

Description

A kind of bumper upper bracket

Technical field

The utility model relates to a kind of link, is specifically related to a kind of bumper upper bracket.

Background technology

as everyone knows, the bumper lower fulcrum of heavy motor vehicle is usually placed on propons in order to accelerate the decay of vehicle frame and vehicle body, because propons is beated and the reason such as wheel steering, the lower fulcrum of bumper is not that in the vertical direction moves, but certain pendulum angle can appear, the traditional bumper upper bracket of modern heavy-duty automobile mostly is the sheet material bending and is welded into the U-shaped structure, in order to reserve enough swing spaces to bumper, larger with support Design often, simultaneously also need to be at two clamping plate of upper bracket top interior welds of U-shaped with fixing bumper, therefore weight and the Fabrication procedure of support have been increased.And the modern heavy-duty automobile is more and more pursued self lightweight and low-cost design.

Summary of the invention

The utility model is in order to overcome the deficiency of above technology, and a kind of one time punching molded and bumper upper bracket that lightweight cost is low is provided.

The technical scheme that its technical matters that overcomes the utility model adopts is:

This bumper upper bracket, the left stile that comprises base plate, forms with respect to the base plate bending and right stile, be arranged at circular hole A and the circular hole B of left stile and right stile upper end and be arranged at some circular hole C on base plate respectively, described left stile and right stile are splayed with respect to base plate and are obliquely installed its upper end open less than lower ending opening, and described circular hole A and circular hole B are coaxial.

Be arranged at respectively on left stile and right stile outer rim and crooked crimp A and crimp B laterally in order to improve upper bracket intensity, also to comprise.

For expendable weight, also comprise profiled holes C, the profiled holes A and the profiled holes B that are arranged at respectively on base plate, left stile and right stile.

The beneficial effects of the utility model are: utilize bolt B that this shock absorber support is fixed on vehicle frame by the some circular hole C on base plate, bolt A utilizes nut namely front shock absorber can be fixed after passing two coaxial circular hole A, front shock absorber and circular hole B.Left stile and right stile form by punching press, with respect to welding manner not only improved support intensity, reduced Fabrication procedure but also alleviated weight.By calculating the pendulum angle of bumper, left stile and right stile can be splayed with respect to base plate and be obliquely installed its upper end open less than lower ending opening, therefore can reserve the pendulum angle space of bumper, can maximized minimizing material weight by rational structure design, reduce manufacturing cost.

The specific embodiment

Be described further below in conjunction with accompanying drawing 1,2 pairs of the utility model of accompanying drawing.

This bumper upper bracket, the left stile 1.2 that comprises base plate 1.1, forms with respect to base plate 1.1 bendings and right stile 1.3, be arranged at circular hole A 1.6 and the circular hole B 1.7 of left stile 1.2 and right stile 1.3 upper ends and be arranged at some circular hole C 1.11 on base plate 1.1 respectively, described left stile 1.2 and right stile 1.3 are splayed with respect to base plate 1.1 and are obliquely installed its upper end open less than lower ending opening, and described circular hole A 1.6 and circular hole B 1.7 are coaxial.Utilize bolt B 5 that this shock absorber support is fixed on vehicle frame 6 by the some circular hole C 1.11 on base plate 1.2, bolt A 3 utilizes nut 4 namely front shock absorber 2 can be fixed after passing two coaxial circular hole A 1.6, front shock absorber 2 and circular hole B 1.7.Left stile 1.2 and right stile 1.3 form by punching press, with respect to welding manner not only improved support intensity, reduced Fabrication procedure but also alleviated weight.By calculating the pendulum angle of bumper, left stile 1.2 and right stile 1.3 can be splayed with respect to base plate 1.1 and be obliquely installed its upper end open less than lower ending opening, therefore can reserve the pendulum angle space of bumper, can maximized minimizing material weight by rational structure design, reduce manufacturing cost.

Also comprise and be arranged at respectively on left stile 1.2 and right stile 1.3 outer rims and crooked crimp A 1.4 and crimp B 1.5 laterally.Crimp A 1.4 and crimp B 1.5 can play the effect of reinforced rib, have effectively improved the intensity of this bumper upper bracket, have extended service life.

Also comprise profiled holes C 1.10, the profiled holes A 1.8 and the profiled holes B 1.9 that are arranged at respectively on base plate 1.1, left stile 1.2 and right stile 1.3.Can process the weight that profiled holes A 1.8, profiled holes B 1.9 and profiled holes C 1.10 can effectively alleviate this bumper upper bracket by modes such as punching presses before to this bumper upper bracket bending manufacturing, meet the trend of modern automobile light-weight design.
