Description
Technical field
The utility model belongs to automobile technical field, specifically, and the particularly afterbody collision protection structure on the manned vehicle.
Background technology
When manned vehicle is knocked into the back, how to reduce injury and automobile tail damage to back row personnel, be the proposition that the automobile design personnel pay close attention to always.Existing manned vehicle afterbody collision protection structure is made up of rear bumper, bump rubber and collision prevention girders, and rear bumper is installed on the manned vehicle tail end, and collision prevention girders is set in rear bumper, fills bump rubber between collision prevention girders and the rear bumper.Though above structure can play certain crashproof effect, the strength that the buffering automobile afterbody is hit is limited, and is not good enough to the protective effect of ride personnel and automobile tail.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of manned vehicle afterbody collision protection structure that can effectively improve crashproof effect.
The technical solution of the utility model is as follows: a kind of manned vehicle afterbody collision protection structure, collision prevention girders (2) is set in rear bumper (1), be filled with bump rubber (3) between this collision prevention girders (2) and the rear bumper (1), the middle part of described bump rubber (3) be provided with a notch preceding bottom land after groove (4), the notch of this groove (4) is towards collision prevention girders (2) upper rear end face, middle part at described bump rubber (3) is embedded with a steel pipe (5) along left and right directions, this steel pipe (5) is positioned at the rear of groove (4), the front end face of steel pipe (5) exceeds the bottom land of groove (4) forward, and has the gap between the aft end face of steel pipe (5) and collision prevention girders (2).
The utility model is set up a steel pipe in bump rubber, this steel pipe is along lateral arrangement, and is positioned at the middle part of rear bumper.When manned vehicle is knocked into the back rear bumper when being subjected to clashing into, at first stressed is bump rubber and steel pipe, and this moment, bump rubber was compressed, steel pipe generation crumple, steel pipe and bump rubber hard-soft energy-absorbing buffering after, just impulsive force can be passed to collision prevention girders, make the stressed generation distortion of collision prevention girders.This shows, the steel pipe energy-absorbing buffering of the utility model by setting up, the buffering automobile afterbody strength of being hit greatly, thus effectively improved the crashproof effect of manned vehicle afterbody, protect personnel's by bus safety and reduced the damage of automobile tail.
Described steel pipe (5) is pipe, draws materials so conveniently, and cost is low.Steel pipe (5) wall thickness is 0.8-1mm, and the wall thickness of steel pipe is too little, and one is impacted is out of shape or damage immediately, and the effect of crumple energy-absorbing is limited; The wall thickness of steel pipe is too big, is difficult to realize distortion, does not have the effect of crumple energy-absorbing.Therefore, the wall thickness of steel pipe is advisable with 0.8-1mm, can reach good energy-absorbing effect.
Have an arc groove (6) over against the position of steel pipe (5) along left and right directions at described collision prevention girders (2) aft end face, the arc radius of described arc groove (6) is slightly larger than the radius of steel pipe (5).Above structure makes collision prevention girders and steel pipe contact position attenuate, like this behind the pipe deformation to the arc groove sunken inside, make the attenuate place of collision prevention girders begin the energy-absorbing that caves in, when pipe deformation sinks in the arc groove fully, just make the stressed generation distortion of whole collision prevention girders, delay the time that impact is delivered to collision prevention girders thus, further improved the effect of energy-absorbing buffering.
Described bump rubber (3) is made by foam, and energy-absorbing function is remarkable like this, and in light weight, and productive costs is low.
In order to ensure structural strength, described collision prevention girders (2) is made by aluminum alloy.
Beneficial effect: the utility model is by setting up a steel pipe in bump rubber; the buffering automobile afterbody strength of being hit greatly; thereby protect the personnel's of riding safety and the damage of minimizing automobile tail, have characteristics such as design is ingenious, simple in structure, transformation is easy, improvement cost is low, applied widely.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, the utility model is made of rear bumper 1, collision prevention girders 2, bump rubber 3 and steel pipe 5 etc.Wherein, rear bumper 1 is installed in the afterbody of manned vehicle, and collision prevention girders 2 is set in rear bumper 1, and this collision prevention girders 2 is made by aluminum alloy.Be filled with bump rubber 3 between collision prevention girders 2 and rear bumper 1, bump rubber 3 is made by foam.Described rear bumper 1, collision prevention girders 2 and bump rubber 3 that form is set is same as the prior art, do not give unnecessary details at this.
As shown in Figure 1 and Figure 2, the middle part of bump rubber 3 be provided with a notch preceding bottom land after groove 4, the notch of this groove 4 is towards collision prevention girders 2 upper rear end faces.Middle part at described bump rubber 3 is embedded with a steel pipe 5 along left and right directions, and this steel pipe 5 is over against the middle part of rear bumper 1 aft end face, and steel pipe 5 parallels with ground.Described steel pipe 5 is positioned at the rear of groove 4, and steel pipe 5 is pipe, and wall thickness is 0.8-1mm, the front end face of this steel pipe 5 exceeds the bottom land of groove 4 forward, and have certain clearance between the aft end face of steel pipe 5 and collision prevention girders 2, the concrete size in this gap is determined according to actual needs, and can be regulated.Steel pipe 5 can be positioned at by bonding mode on the bump rubber 3, also can be positioned on the bump rubber 3 by flush fit or other similar mode.Have an arc groove 6 over against the position of steel pipe 5 along left and right directions at described collision prevention girders 2 aft end faces, the arc radius of described arc groove 6 is slightly larger than the radius of steel pipe 5 cylindricals, and steel pipe 5 can be absorbed in the arc groove 6 fully.
Principle of work of the present utility model is as follows:
When manned vehicle is knocked into the back rear bumper 1 when being subjected to clashing into, at first stressed is bump rubber 3 and steel pipe 5, this moment, bump rubber 3 was compressed, crumple takes place in steel pipe 5, behind steel pipe 5 and bump rubber 3 hard-soft energy-absorbing bufferings, the attenuate place of collision prevention girders 2 (arc groove 6) just begins the energy-absorbing that caves in, and when steel pipe 5 distortion sink in the arc groove 6 fully, just makes whole collision prevention girders 2 stressed generation distortion.
