Abstract
The invention relates to an energy absorbing type bumper which comprises a bumper body and a frame. At least one energy absorbing mechanism is installed between the bumper body and the frame. Each energy absorbing mechanism comprises a front connecting plate, a pressure spring shaft, a protecting pressure spring, a rear connecting plate, a pre-tightening nut, a folded plate, a retaining spring, an alloy retaining block and a retaining spring gland. The bumper has the advantages that by means of the energy absorbing mechanisms installed between the bumper and the frame, when the bumper is collided, the pressure spring shafts retreat to compress disc springs, and energy generated by collision can be absorbed by the disc springs. Compared with a traditional bumper, the security coefficient of the bumper is greatly improved; the bumper is wide in application field, and can be applied to motor vehicles such as a truck or a car.
Description
Technical field
The present invention relates to a kind of bumper/spoiler, particularly a kind of energy absorbing bumper.
Background technology
No matter is at present lorry, family-sized car, at present because the reasons such as Impact energy is limited are offset in the bumper/spoiler crumple of automobile product front end, effectively can not offset the personnel and vehicle that shock produces when shock accident occurs before, trailing arm is out of shape personnel and property damage.
Summary of the invention
For overcoming the defect of prior art, the invention provides a kind of energy absorbing bumper, technical scheme of the present invention is: a kind of energy absorbing bumper, comprise bumper body and vehicle frame, at least one energy absorber is installed between described bumper body and vehicle frame, each energy absorber includes front gusset piece, compression spring axis, protection stage clip, rear gusset piece, pre-load nut, fold plate, retaining spring, alloy retreat stop block and retaining spring capping, side and the bumper body of described front gusset piece link together, opposite side is provided with compression spring axis, the other end of this compression spring axis is arranged on vehicle frame through what slide after rear gusset piece, the periphery being arranged on the compression spring axis of one end of vehicle frame is provided with the multistage convex slope coordinated with alloy retreat stop block, described protection compression spring sleeve is contained on compression spring axis, between front gusset piece and rear gusset piece, this rear gusset piece is arranged on vehicle frame by fold plate, and described pre-load nut is arranged on compression spring axis, is positioned at the inner side of rear gusset piece, and spacing by rear gusset piece, described retaining spring capping is arranged on vehicle frame, one end of retaining spring is arranged on the side of retaining spring capping, the other end is provided with alloy retreat stop block, and what described alloy retreat stop block slided is arranged on retaining spring capping, and described retaining spring is vertical with compression spring axis to be arranged.
Described protection stage clip comprises several disc spring unit, and each disc spring whole unit is olive shape structure, comprises the disc spring that two structures are identical, is formed being combined by two disc springs; Wherein, the disc spring thickness more close to bumper body is thicker.
Described energy absorber is four, and every two is one group, being arranged in bumper body of two groups of energy absorber symmetries.
Described energy absorber is two, and symmetrical is arranged in bumper body.
Advantage of the present invention is: as product of the present invention being arranged on the middle part of driving engine or driving compartment, protection is formed to driving engine and driving compartment, the effect that superpower shock offsets last one Impact energy afterwards can be reached, can offsetting according to automobile impacting energy cascade, therefore can becoming the last safety curtain to driving people.

Fig. 2 is the agent structure schematic diagram (energy absorber is two) of the second embodiment of the present invention;
Fig. 3 is the P place enlarged drawing of Fig. 1.
Detailed description of the invention
Further describe the present invention below in conjunction with specific embodiment, advantage and disadvantage of the present invention will be more clear along with description.But these embodiments are only exemplary, do not form any restriction to scope of the present invention.It will be understood by those skilled in the art that and can modify to the details of technical solution of the present invention and form or replace down without departing from the spirit and scope of the present invention, but these amendments and replacement all fall within the scope of protection of the present invention.
See Fig. 1 to Fig. 3, the present invention relates to a kind of energy absorbing bumper, comprise bumper body 1 and vehicle frame 2, between described bumper body 1 and vehicle frame 2, at least one energy absorber is installed, as shown in Figure 1, described energy absorber is four, every two is one group, two groups of energy absorber symmetries be arranged in bumper body 1, each energy absorber includes front gusset piece 2, compression spring axis 6, protection stage clip 3, rear gusset piece 4, pre-load nut 7, fold plate 5, retaining spring 10, alloy retreat stop block 11 and retaining spring capping 9, side and the bumper body 1 of described front gusset piece 2 link together, opposite side is provided with compression spring axis 6, the other end of this compression spring axis 6 is arranged on vehicle frame 12 through what slide after rear gusset piece 4, the periphery being arranged on the compression spring axis 6 of one end of vehicle frame 12 is provided with the multistage convex slope 8 coordinated with alloy retreat stop block 11, described protection stage clip 3 is sleeved on compression spring axis 6, between front gusset piece 2 and rear gusset piece 4, this rear gusset piece 4 is arranged on vehicle frame 12 by fold plate 5, and described pre-load nut 7 is arranged on compression spring axis 6, is positioned at the inner side of rear gusset piece 4, and spacing by rear gusset piece 4, described retaining spring capping 9 is arranged on vehicle frame 12, one end of retaining spring 10 is arranged on the side of retaining spring capping 9, the other end is provided with alloy retreat stop block 11, what described alloy retreat stop block 11 slided is arranged on retaining spring capping 9, described retaining spring 10 is vertical with compression spring axis 6 to be arranged, and namely retaining spring is arranged along the radial direction of compression spring axis.
Described protection stage clip 3 comprises several disc spring unit, and each disc spring whole unit is olive shape structure, comprises the disc spring that two structures are identical, is formed being combined by two disc springs; Wherein, the disc spring thickness more close to bumper body is thicker.
The difference of Fig. 2 and Fig. 1 is only that the quantity of energy absorber is different, and described energy absorber is two, and symmetrical is arranged in bumper body.
Principle of work of the present invention is: after bumper body is clashed into, compression spring axis moves backward, moving down of compression spring axis makes protection stage clip be extruded, produce antagonistic force, the convex slope extruded alloy retreat stop block simultaneously on compression spring axis, makes alloy retreat stop block move to side, after shock completes, alloy retreat stop block resets under the effect of retaining spring, again coordinates with other convex slope, completes fixing compression spring axis.
