Abstract
The utility model relates to a double-layer shock-absorbing bumper for automobiles. The bumper is double-layered. At least three shock-absorbing devices (3) are uniformly loaded between two layers of bumpers (1, 2). A motor power cut mechanism and an automatic brake mechanism are also arranged on the double layers of bumpers. When an automobile generates accidental collision, the double-layer shock-absorbing bumper for automobiles can simultaneously finish motor stopping, braking and multi-energy buffer shock absorption process in moment, and can effectively absorb huge impact force and farthest reduce the loss of collision accident.
Description
The utility model relates to a kind of anticollision damping device that is used for automobile, more specifically says, is the double-deck Shockproof type bumper/spoiler of a kind of automobile.
At present, known Federal bumper is to make a long thick stick with metal sheet or plastics, is connected with screw on the front cross rail of automobile.When automobile met accident collision, this bumper/spoiler effect was little, the enormous impact power that produces when it can't absorb collision.In order to alleviate the heaviness loss that car accident is brought to people, rubber block or spring are installed in existing research additional on Federal bumper, and what have installs liquid damper additional, but effect is unsatisfactory.
The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art, when providing a kind of automobile to meet accident collision, not only can pass through multi-buffer, damping in moment, and can in time make motor outage, self-stopping double-deck Shockproof type bumper/spoiler.
The purpose of this utility model is achieved in that before automobile crossbeam foremost, and the double-layer safety thick stick is installed in the position of former bumper/spoiler, evenly installs at least three Shock absorbers that are made of spring and hydraulic actuating cylinder between two-layer bumper/spoiler additional.The motor power cutoff mechanism is set on the double-layer safety thick stick, it is near on the second layer bumper/spoiler of car body at least one dragline type cut-off switch to be set, stay cord is tied up to the lower end of a corresponding pull bar, the upper end of this pull bar is vertically fixed on the ground floor bumper/spoiler, and pass circular hole on the second layer, bearing fit between pull bar and the circular hole.On the double-layer safety thick stick, automatic brake mechanism is set, it is on the ground floor bumper/spoiler, at least vertically fix a push rod, accordingly on second layer bumper/spoiler, fix an annulus fulcrum, have an end and the push rod of a connecting rod hinged accordingly, the other end passes annulus and is connected with the brake backguy, and is hinged between annulus and the connecting rod.
The utility model has been compared following advantage and good effect with prior art: owing to adopt the double-layer safety thick stick, and a plurality of Shock absorbers are set between two-layer bumper/spoiler, therefore, when automobile meets accident collision, at first contact with the ground floor bumper/spoiler, impulsive force absorbs through a plurality of Shock absorbers then, reach second layer bumper/spoiler again, through multistage absorption, buffering, slow down impact widely like this, alleviated economic loss and driver and conductor's injures and deaths effectively.Owing to also be provided with motor power cutoff mechanism and automatic brake mechanism on the double-layer safety thick stick, after bumper/spoiler is collided impulsive force, pull bar fixed thereon, push rod are bounced back with bumper/spoiler, and pulling motor cut-off switch and brake backguy, make the driving engine viscous motion, the brake more and more tighter, in a moment, finish motor viscous motion, brake, multi-buffer, damping process simultaneously like this, absorb huge impact effectively, farthest reduce the loss of car accident.
Below in conjunction with accompanying drawing, structure of the present utility model is further described by embodiment.
Fig. 1 is a structural representation of the present utility model;
As shown in Figure 1, the double-deck Shockproof type bumper/spoiler of a kind of automobile, its bumper/spoiler is same as the prior art, synthesizes strip shape by rubber, metallic support, horizontal front end at automobile.Different with prior art is to adopt the double-layer safety thick stick, and between ground floor bumper/spoiler 1 and the second layer (near car body) bumper/spoiler 2, evenly installs the Shock absorber 3 that is made of spring and hydraulic actuating cylinder additional.The volume cost embodiment of Shock absorber has provided three, also can be 4 to 6, and effect can be better.
As shown in the figure, the motor power cutoff mechanism also is set on the double-layer safety thick stick, it is near on the second layer bumper/spoiler 2 of car body a dragline type cut-off switch 4 to be set, stay cord 5 is tied up to the lower end of a pull bar 6, the upper end of pull bar 6 is vertically fixed on the ground floor bumper/spoiler 1, and pass the circular hole of second layer bumper/spoiler 2, and pull bar and circular hole bearing fit, motor power line 11 installs around on second layer bumper/spoiler.For the purpose of reliable, the said motor power cutoff mechanism can be provided with a plurality of simultaneously on the double-layer safety thick stick, generally needs one to three cover.Backguy 5 has two kinds, and the one, there is not elasticity, be mainly used in the vehicle of direct cable formula brake gear, promptly motor cuts out the vehicle that the back brake is still worked.The 2nd, flexible, pulling force is just arranged after extending 2 times, be mainly used in the vehicle that brake must just be worked when motor is opened.
As shown in the figure, automatic brake mechanism also is set on the double-layer safety thick stick, it is push rod 7 of vertical fixing on ground floor bumper/spoiler 1, correspondingly on second layer bumper/spoiler 2, fix an annulus fulcrum 8, connecting rod 9 one end pass annulus and push rod is hinged, the other end is connected with brake backguy 10, and annulus 8 is hinged with connecting rod 9.For the purpose of reliable, above-mentioned automatic brake mechanism can be provided with two covers simultaneously on the double-layer safety thick stick, and effect can be better.
Above-mentioned double-deck Shockproof type bumper/spoiler is not only applicable to various automobile, is applicable to other four-wheel motor vehicless simultaneously yet.
Working process of the present utility model:
When automobile met accident collision, ground floor bumper/spoiler 1 was impacted, and absorbs impact first; Pass to after bumper/spoiler is stressed on the Shock absorber 3, absorb impact for the second time; Last subsequently impulsive force passes to again on the second layer bumper/spoiler 2, absorbs impact once more.Like this, through multistage slowing down, huge impact major part is absorbed by bumper/spoiler, thereby reduced the damage rate of vehicle and personnel's injures and deaths widely.When ground floor bumper/spoiler 1 was subjected to impulsive force, pull bar 6 fixed thereon bounced back automatically.Be the also stressed Drawing switch 4 of stay cord 5 thereon simultaneously, can make the driving engine viscous motion by power cut-off.When ground floor bumper/spoiler 1 was subjected to impulsive force, push rod 7 fixed thereon was subjected to its pressure, promoted and its pivotally attached connecting rod 9, and connecting rod 9 is by annulus fulcrum 8 pulling brake backguys 10 drags.
