Abstract
The utility model discloses a kind of truck rear bumper, including side plate, side cushion hole, rubber pneumatic bag, induction hole, bearing pin, positive plate, installing plate, cushioning supportive plate and spring, the side plate fixes the top side and bottom side for being welded in installing plate, the side plate is provided with side cushion hole, the positive plate is provided with positive cushion hole, the rubber pneumatic bag is located at the front side of positive plate, the bearing pin is through being connected between positive plate and installing plate, the spring on bearing pin, fix and be welded between positive plate and installing plate by the cushioning supportive plate.The truck rear bumper buffering energy-absorbing effect is obvious, when the less rear-end collision of vehicle generation impulsive force, only there is less deformation, and most of power is absorbed by the rubber pneumatic bag being arranged on positive plate, because rubber pneumatic bag is flexible material, larger damage will not be caused to rear car, when vehicle occurs the larger rear-end collision of impulsive force, the truck rear bumper can fully occur degeneration, and impact force is absorbed.
Description
Technical field
The utility model is related to technical field of automobile components, specially a kind of truck rear bumper.
Background technology
Bumper is to absorb to relax foreign impacts power, the safety device of protection vehicle body front and rear part.When colliding, protect
Dangerous thick stick can protect vehicle body, it is to avoid vehicle body is directly collided.For low speed collision, it can play protection and make by dispersing impact forces
With, but it is poor to the protectiveness of the car body component of rear car, and during the collision of existing bumper generation speed, shock resistance
Lack in ability, buffering effect is poor, protective effect also has limitation.
Existing truck rear bumper is mainly and is rigidly attached on chassis, and its own occurs during rear-end impact can be with
Some energy are absorbed, but quite a few is then delivered in rear car, so as to cause rear car casualties, therefore how to provide one kind
The bumper of good buffer effect, it has also become problem demanding prompt solution.
Utility model content
The purpose of this utility model is to provide a kind of truck rear bumper, to solve to be proposed in above-mentioned background technology
Existing truck rear bumper occur less rear-end collision when it is poor to the protectiveness of rear car, and generation it is larger
During rear-end collision, the problem of degeneration energy-absorbing can not be well carried out again.
To achieve the above object, the utility model provides following technical scheme：A kind of truck rear bumper, including side
Plate, side cushion hole, rubber pneumatic bag, induction hole, bearing pin, positive plate, installing plate, cushioning supportive plate and spring, the side plate fix weldering
The top side and bottom side of installing plate are connected to, the side plate is provided with side cushion hole, and the positive plate is provided with positive cushion hole, the rubber
, located at the front side of positive plate, the bearing pin is through being connected between positive plate and installing plate, and the spring is described on bearing pin for air bag
Cushioning supportive plate is fixed and is welded between positive plate and installing plate.
Preferably, the side plate and positive plate are the integral structure being stamped and formed out.
Preferably, the side plate forms U-shape structure with the section of positive plate.
Preferably, the cushioning supportive plate is wavy shaped configuration.
Preferably, the rubber pneumatic bag is symmetrical above and below altogether is provided with two.
Compared with prior art, the beneficial effects of the utility model are：The truck rear bumper being capable of fully conquassation
Deformation, buffering energy-absorbing effect is obvious；So as to reduce injury during car rear-end to rear car, when vehicle occurs that impulsive force is less chases after
During tail accident, only there is less deformation in the truck rear bumper, and most of power is by the rubber gas that is arranged on positive plate
Capsule absorbs, and because rubber pneumatic bag is flexible material, larger damage will not be caused to rear car, when vehicle generation impulsive force is larger
During rear-end collision, the truck rear bumper can fully occur degeneration, and impact force is absorbed, and cushioning supportive plate is subject in moment
Extruding, fully deforms upon, and the induction hole being arranged on positive plate can make the deformation of cushioning supportive plate more abundant, while side plate
Can deform upon, spring further absorbs to impact force, by a series of deformation by the maximized absorption of impact force.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the utility model Section A-A schematic diagram.
In figure：1st, side plate, 2, side cushion hole, 3, rubber pneumatic bag, 4, induction hole, 5, bearing pin, 6, positive plate, 7, installing plate, 8,
Cushioning supportive plate, 9, spring.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of truck rear bumper, including side plate
1st, side cushion hole 2, rubber pneumatic bag 3, induction hole 4, bearing pin 5, positive plate 6, installing plate 7, cushioning supportive plate 8 and spring 9, side plate 1 are consolidated
Surely the top side and bottom side of installing plate 7 are welded in, side plate 1 is provided with side cushion hole 2, and positive plate 6 is provided with positive cushion hole 4, rubber gas
Located at the front side of positive plate 6, through being connected between positive plate 6 and installing plate 7, spring 9 buffers branch to bearing pin 5 to capsule 3 on bearing pin 5
Fagging 8 is fixed and is welded between positive plate 6 and installing plate 7.
In above-described embodiment, specifically, side plate 1 is the integral structure being stamped and formed out with positive plate 6, meanwhile, survey cushion hole 2
Obtained also by punching press with induction hole 4, side plate 1 forms U-shape structure with the section of positive plate 6, forms good supporting construction.
In above-described embodiment, specifically, cushioning supportive plate 8 is wavy shaped configuration, corrugated structure makes cushioning supportive plate 8
Can fully be deformed upon when extruding is received, and by deformation energy-absorbing.
In above-described embodiment, specifically, rubber pneumatic bag 3 is symmetrical above and below be altogether provided with two, because rubber pneumatic bag 3 is flexible material
Material, when the less rear-end collision of the power that collides, can preferably protect rear vehicle body not damage.
Operation principle：When using the truck rear bumper, need have one to whole truck rear bumper first
