Abstract
The utility model relates to a bumper which comprises a beam arranged in the width direction of an automobile. Energy absorption boxes arranged in the longitudinal direction of the automobile are arranged at the two ends of the beam, connecting columns extending in the longitudinal direction of the automobile are arranged at the two ends of the beam, one end of each connecting column is inserted in the rear middle portion of the corresponding energy absorption box to be in sliding fit with the corresponding energy absorption box, a buffer space is reserved between the end portion of the end, inserted into the corresponding energy absorption box, of each connecting column and the box wall surface, opposite to the end of the corresponding connecting column, of each energy absorption box, and blind holes are formed in the axial direction of the connecting columns, one end of a supporting spring is inserted into the corresponding blind hole, and the other end of the supporting spring is connected with the box wall surface of the corresponding energy absorption box. The bumper can absorb vibration impact energy after collision so as to reduce injury to persons and damage to the automobile.
Description
Technical field
The utility model relates to the protective device on a kind of car body, is specifically related to bumper/spoiler.
Background technology
Bumper damper meets study plot and is arranged on front and rear side in automobile, to absorb the collision energy of less collision process, thereby does not damage as much as possible supporting structure of automobile itself.Bumper damper consists of crossbeam conventionally, and it can fix transverse to the longeron of automobile frame in the situation that packing collision energy absorbing box into.Crossbeam, for the energy being caused by impact is imported to collision energy absorbing box, is transformed into distortion by collision energy there.
Known various heteroid bumper damper.By US6,349,521B1, the bumper damper with crossbeam rigidity, that be configured to box girder belongs to prior art.The cross-sectional plane of crossbeam along it length and change, to give it, bear suitable load and high energy absorption capacity.
Summary of the invention
For above-mentioned technical matters, main purpose of the present utility model is for a kind of bumper/spoiler is provided, to colliding absorbing vibration impact energy afterwards.
Bumper/spoiler, comprise a crossbeam of arranging along vehicle width direction, in two ends of crossbeam, be provided with the energy-absorption box of arranging along automobile longitudinal, two ends of described crossbeam are equipped with along the joint pin of car body longitudinal extension, one end of this joint pin is inserted into rear in energy-absorption box and energy-absorption box formation bearing fit, joint pin is inserted into the end of the one end in energy-absorption box, between the box wall relative with energy-absorption box, leave the spacing of buffering, along joint pin axial arranged, there is blind hole, one end of a support spring is inserted in blind hole, the other end of support spring is connected with the box wall of energy-absorption box.
The cross-sectional configuration of described crossbeam becomes U-shaped or square shape.
Described crossbeam is provided with reinforcing profile towards the one side of car body, and this reinforcing profile is T-shaped, and extends along the longitudinal direction of car body.
Adopted such scheme, when the front of car body or side are subject to impacting, be delivered to joint pin after beam force, joint pin passes to support spring.If impulsive force is little, directly by support spring, absorbed and stored, can not impact car body.If impulsive force is excessive, side support spring absorbs most of impulsive force to store, and the impulsive force of fraction is transmitted to the longeron on car body by energy-absorption box, because the supported spring of most impulsive force absorbs, therefore, the impulsive force of fraction can not produce large impact to the longeron of car body.Therefore, the utility model is by the effect of joint pin, support spring and energy-absorption box, all can reduce the injury that impulsive force causes car or people.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the section-drawing along A-A line in Fig. 1;
1 is crossbeam, and 2 is energy-absorption box, and 3 is joint pin, and 4 is support spring, and 5 is reinforcing profile.
The specific embodiment
See figures.1.and.2, a kind of bumper/spoiler of the present utility model, comprises a crossbeam 1 of arranging along vehicle width direction, is provided with the energy-absorption box 2 of arranging along automobile longitudinal in two ends of crossbeam 1.Two ends of described crossbeam are equipped with the joint pin 3 along car body longitudinal extension, one end of this joint pin 3 is inserted into rear in energy-absorption box and energy-absorption box formation bearing fit, joint pin is inserted into the end of the one end in energy-absorption box, leaves the spacing of buffering between the box wall relative with energy-absorption box.Along joint pin 3 axial arranged, have blind hole, one end of a support spring 4 is inserted in blind hole, and the other end of support spring is connected with the box wall of energy-absorption box.The cross-sectional configuration of described crossbeam 1 becomes U-shaped or square shape.Described crossbeam is provided with reinforcing profile 5 towards the one side of car body, and this reinforcing profile is T-shaped, and extends along the longitudinal direction of car body.
