Abstract

The invention relates to a front and back bumper device for ensuring vehicle safety, which comprises a bumper frame and a decorative cover and is characterized in that at least two springs are arranged at the middle parts of a connecting plate and the bumper frame; one ends of the springs are fixedly connected with the bumper frame through bolts or in a welding way, and the other ends of the springs are fixedly connected with the connecting plate through bolts or in a welding way; the coarseness and the hardness of the springs are larger than the coarseness and the hardness of general springs; the heights of the three springs at the front part of the bumper frame are inconsistent, wherein the heights of the springs at the two sides are lower than that of the spring at the middle part; the front parts of the springs at the two sides are in an inclined surface shape and are fixedly connected with the connecting plate; and the connecting plate has a certain radian and is designed in a concave-convex way to be used as a bottom bracket of the decorative cover. The invention has the advantages of simple structure, low manufacturing cost, strong impact resistance and convenient maintenance.

Description

A kind of front and back bumper device for ensuring vehicle safety
Technical field
The present invention relates to a kind of front and back bumper device for ensuring vehicle safety.
Background technology
At present, known automobile impact-reducing device is made up of two poles that are fixed on frame lug and be through on the bearing.Be respectively installed with stage clip and top spring on two poles, when stage clip is hit when being compressed, can eject by the former top spring that is in compressive state of percussion, its drawback is, complex structure, the power that is hit is poor, the known technology that also has is, between bumper/spoiler skeleton 1 and cover of upholstery (3) deformable foam (2) is set, and its drawback is, when vehicle has bigger bump, after deformable foam (2) is crushed, will cause the distortion of bumper/spoiler skeleton (1), the damaged vehicle degree is strengthened, can cause bigger economic loss, hidden danger also can improve.
Summary of the invention
Deficiency at above-mentioned technical matters exists the purpose of this invention is to provide a kind of front and back bumper device for ensuring vehicle safety.
Technical scheme of the present invention is as follows:
A kind of front and back bumper device for ensuring vehicle safety, comprise bumper/spoiler skeleton, cover of upholstery, it is characterized in that: the middle part at connecting panel and bumper/spoiler skeleton is provided with at least two springs, described spring one end is connected and fixed by bolt or welding manner and dangerous thick stick skeleton, and the other end is connected and fixed by bolt or welding manner and connecting panel.
Be provided with three springs at the middle part of connecting panel and bumper/spoiler skeleton.
Described spring is to have than thick rugosity of general spring and the hardness harder than general spring.
The height of three springs of described bumper/spoiler skeleton front portion is inconsistent, the spring in the middle of the height of its both sides spring is lower than.
The front portion of described both sides spring takes the form of inclined plane and connecting panel is connected and fixed.
Described connecting panel has certain radian, as the bottom bracket concave-convex design of cover of upholstery.
Described bumper/spoiler frame design has certain radian.
Spring should design the arc inclined-plane of spring with the radian of bumper/spoiler skeleton.
Spring one end and bumper/spoiler skeleton are connected and fixed the back other end and connecting panel is fixed, and mount the cover of upholstery of constant weight on connecting panel.
The invention has the beneficial effects as follows: simple in structure, cost is low, and anti-impact force is strong, and is easy to maintenance.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present invention;
Fig. 2 is a known technology structural representation of the present invention.
Among the figure: 1 bumper/spoiler skeleton, 2 deformable foam, 3 cover of upholstery, 4 springs, 5 connecting panels.
The specific embodiment
As shown in Figure 1, middle part at connecting panel 5 and bumper/spoiler skeleton 1 is provided with three springs 4 or at least two springs 4, one end of described spring 4 is connected and fixed by bolt or welding manner and dangerous thick stick skeleton 1, and the other end is connected and fixed by bolt or welding manner and connecting panel 5.Inside in cover of upholstery 3 is provided with buckle, in order to block connecting panel 5.
The deformable foam 2 that spring 4 of the present invention replaces in the known technology when vehicle is subjected to clashing into, plays buffer action, to guarantee personal safety.
The height of three springs 4 of described bumper/spoiler skeleton 1 front portion is inconsistent, the spring 4 in the middle of the height of its both sides spring 4 is lower than.The front portion of described both sides spring 4 takes the form of inclined plane and connecting panel 5 is connected and fixed.
Described spring 4 has than the thick rugosity of general spring and has the hardness harder than general spring, because of being connected and fixed the back other end, spring 4 one ends and bumper/spoiler skeleton 1 fix with connecting panel 5, and mount the cover of upholstery 3 (comprising: what have is provided with light fixture etc.) of constant weight, like this, after described spring 4 has the cover of upholstery 3 that an end mounts tens kilogram weights, do not have any rocking or labile factor, when several tons impulsive force is arranged again, described spring 4 just plays flexible buffer action, thereby has reduced the damage of the miscellaneous part on bumper/spoiler skeleton 1 and the bumper/spoiler skeleton 1.
Described connecting panel 5 has certain radian, as the bottom bracket concave-convex design of cover of upholstery 3.
In order to make bumper/spoiler skeleton 1 have stronger anti-impact force, when design insurance thick stick skeleton 1, also certain radian should be arranged.If bumper/spoiler skeleton 1 has certain radian, when the spring 4 on both sides was set, the contact surface of spring 4 and bumper/spoiler skeleton 1 also should design the inclined-plane of spring 4 with the radian of bumper/spoiler skeleton 1.
