Description

Vehicle collision impairment device

The utility model can alleviate personnel when being a kind of collision happens, and the safety device of article damage and loss specially refers to a kind of vehicle collision impairment device.

The vehicle of prior art 1. all is fixed on vehicle body because of the front and back bumper/spoiler or is connected as a single entity with vehicle body, and when car and car or other objects, car and people do not have buffering leeway when colliding; 2. the power that can not break automatically during vehicle collision starts braking, this in driver's moment of desperation mistake with throttle when braking, the consequence of generation is more serious; 3. the alarm free ring when having an accident and break down of existing vehicle is shown, preceding vehicle has had an accident or the fault back vehicle is not but also known when poor visibility, collision accident so several of easy generations even up to a hundred cars knock into the back. although at present the traffic accident that is caused by automobile is had many countrmeasures, cause personnel, damage to property every year thus still is startling.The utility model will to a certain degree address the above problem.

The purpose of this utility model just is to alleviate above-mentioned various deficiencies of the prior art: one, when before and after vehicle takes place, colliding, 1. can alleviate impact strength, 2. can the self-opening chimes of doom and the double jump Warning light, in time take to dodge or the rescue measure with personnel around reminding and vehicle. two: when vehicle generation frontal collisions, 1. startup brake equipment: 2. disconnected power, to alleviate the accident degree. (if collision starts braking and disconnected power may increase impact strength behind the car)

The purpose of this utility model is achieved in that it comprises bumper/spoiler, strut bar before and after the vehicle, is enclosed within spring on the strut bar, the shim between strong and weak spring, strut bar chute, strut bar baffle plate alarm speaker and the various device and the configuration of vehicle in the technology at present.It is characterized in that: the front and back bumper/spoiler of vehicle is not fixed on the vehicle body or with vehicle body and connects together, but the strut bar (being with spring on the strut bar) by the bumper/spoiler inboard, strut bar penetrates the chute on the vehicle chassis, and gets in touch with vehicle body; Bumper/spoiler can vertically move with vehicle body within the specific limits; When bumper/spoiler when the vehicle body direction moves, spring resistibility behind the bumper/spoiler plays the effect of damp impacts dynamics, starts to report to the police by bumper/spoiler and by parts such as the strut bar displacement that its drives simultaneously and blows a trumpet, the caution of double jump lamp, disconnected power, starts braking to reduce the loss.Further specify particular case of the present utility model below in conjunction with example.

Each parts installation order of vehicle collision impairment device and using method are as follows:

Chute among Fig. 4 (it also can be more than two and two that chute can be one), the strut bar baffle plate among Fig. 5 all is fixed on vehicle chassis or the crossbeam; Strut bar puts the more weak spring of elasticity earlier and puts shim (shape such as plain washer) again, the spring that elasticity is stronger, strut bar is inserted in Fig. 4 chute hole then, insert strut bar pinhole (Fig. 1 with pin again, in 2 2), chock among Fig. 3 is positioned at strut bar band tooth and (sees Fig. 1, in 2 1) that section, when utilizing elastic force or gravity, strut bar chock when the vehicle body direction bounces back falls into that tooth paddy is blocked strut bar in case bumper/spoiler rebounds in the weak spring moving region, one blows a trumpet thereby can keep vehicle to be in warning, open the caution of double jump lamp, disconnected power, start braking mode, (when chock is mentioned, bumper/spoiler resets and promptly stops described state); Two can prevent being injured by the secondary of collision body by weak tendencies such as the persons of thrusting into.

Strut bar baffle plate among Fig. 5 is in order to stop strut bar and institute's bar carrier thereof to bounce back without end, thereby guarantees vehicle body and occupant, and article are suffered a loss less.

Strut bar thickness among Fig. 1 will match with the chute bore among Fig. 6, move otherwise too tightly can block strut bar, thereby Tai Song easily causes the shake (between long more or two chutes of chute length distance draw money on credit more strut and bumper/spoiler are not easy more to shake) of strut bar and bumper/spoiler because of the vehicle ' moderately gusty air again influences result of use.Another function by the chute of spring is: so it plays the supporting role of spring recoil because of chute one end and spring join.The bumper/spoiler of vehicle should be by the big material of intensity, otherwise damage vehicle body and occupant easily can be because of the little object of collision electric pole and so on hard striking face the time so also can make this device more reliable in addition.Thereby strut bar is that sensitivity in order to ensure this device more in time start above-mentioned every safety device with elasticity than weak spring by an end of bumper/spoiler, can alleviate in addition the people, weak tendencies such as bicycle are hit the damage of thing, and the strong spring of elasticity is the main force of vehicle self-protection, and the strut bar baffle plate then is the last preventive means in this device.

Can bounce back in vehicle body because of the vehicle collision back support rod with said apparatus, so can utilize moving of bumper/spoiler and strut bar upwards to withstand throttle or power supply, power pedals such as air feed are depressed brake pedal.Concrete method and principle and uncomplicated are as requirement as described in reaching by methods such as fluid power, gear, cam, bent axle, lever transmissions.Only lift wherein the simplest a kind of being illustrated below, all the other repeat no more.Round dot 1 among Fig. 6 is a balance pivot, and lever rotates when strut bar bump lever 2 parts, and its other end 3 can counter motion remove to withstand the power pedal, in like manner as long as above-mentioned lever also can be depressed brake pedal by straight change is curved.The continuation retraction moves and also can unrestrictedly not push lever, (wherein 1 is strut bar, and 2 is lever) as shown in Figure 7 after strut bar pushes up desired location with lever.As for how starting behind the vehicle collision caution of chimes of doom and double jump lamp is also very simple, same because bumper/spoiler retraction drive strut bar and even chock shown in Figure 3 displacement therein any one parts connect described device switch just.For example, on strut bar, establish a rectangle material, one section is an insulating material, another section be for conduction, annunciator generally speaking, and two joints of double jump lamp lead contact insulator simultaneously, thereby these two joints contact current-carrying part simultaneously and finish described function after the strut bar displacement, just a cover switch of establishing in addition in the switch that opens and closes of collision back and the car can independently separately use, so that under the non-collision situation, as the vehicle et out of order and stagnation of movement or send and repair use in the way.

Certainly bumper/spoiler does not fixedly make it flexible, thereby the method for buffering collision of closed dynamics uses spring a kind of incessantly, other method is also just like external pasting in the bumper/spoiler or filled rubber, sponge, air bag elastomeric material or springing, but from the volume of material, weight and result of use each side is spring the best relatively still.

Very easily causing catastrophic injury to alleviate this problem to the outer personnel of car and dilly during the bumper/spoiler of full size vehicle of the prior art is liftoff higher getting into an accident can 1, the reduction bumper height, to prevent that hitting the tragedy that afterwards rolls earlier takes place again; Can prevent that also the dilly fore-and-aft direction from piercing at the bottom of the car; 2, increase the bumper/spoiler width, thereby when bump, reduce being hit the pressure at position.The device for reducing collision damage that Oversize vehicle adopts is as described below:

Fig. 8 is an Oversize vehicle device for reducing collision damage structural representation, 1 chute that is equivalent in noted earlier wherein, and 2 is strut bar, and 3 is strong spring, and 4 is the spring shim, and 5 is weak spring, and 6 for connecting the chassis hole, and 7 for connecting the bumper/spoiler hole, and 8 is pinhole; Fig. 9 is the bumper/spoiler lateral plan, and wherein 1 is bumper/spoiler and body contact hole, the 2nd, and bumper/spoiler and strut bar connecting bore are opened strip shape openning supply and marketing and are moved on the chute, also limit the strut bar motion simultaneously.Bumper/spoiler all is connected as hinge with chassis with bumper/spoiler, chute with vehicle body, strut bar, when bumper/spoiler is that fulcrum is when direction changes in car with 1, strut bar and spring behind the bumper/spoiler play buffer action, all the other functions and using method and similar no longer repetition noted earlier.

Since vehicle bumper can after move and must stay certain space, so bumper/spoiler two rear flank ends must shortage one section, also have the slit in addition between bumper/spoiler and vehicle body, thereby not attractive in appearance.The method that solves these two problems is: 1, the part of bumper/spoiler shortage peace " bumper/spoiler sheath ", its outward appearance, material, color and bumper/spoiler will be coordinated, hide bumper/spoiler shortage part with it, when bumper/spoiler bounced back, bumper/spoiler two sides can contract in " bumper/spoiler sheath "; 2, place, the slit between bumper/spoiler and vehicle body establishes decorative moulding, covers even beautification function to rise.
