Abstract

The utility model relates to a vehicle-protecting safety anti-collision device, which can lighten damage of passengers when a vehicle generates accidental collision. The vehicle-protecting safety anti-collision device is suitable for being assembled by light-type passenger cars, microbuses or cars. The device is assembled at the lower part of a vehicle front bumper, is mutually assembled by an anti-collision bumper, an elastic push post, an aggravated push spring, a push-and-pull piston and a fixed mount; a suit of electric pushing-out or retracting anti-collision bumper device is additionally added. The anti-collision bumper and the elastic push post are led out of the vehicle for a definite distance. When a collision occurs, the aggravated push spring is used as the soft absorption of vehicle collision gravity for achieving that collision strength is reduced or lightened; the personnel safety or economic loss of drivers and passengers is ensured.

Description

Protect car formula anticollision device

The utility model relates to a kind of automotive safety collision prevention device, particularly a kind ofly is used for various vehicles and is used for the anticollision device of preventing collision protection.

We know; automobile is being turned; descending; culvert or brake failure; stop partially; and for example meet strong wind; dense fog; because ground-surface situation difference; or rain; it is icing to snow; adhesion of tyres significantly reduces; wheel takes place slippery easily; these can cause the automobile accident that collides; according to the pertinent data introduction; at present external expert wants computer is used for the vehicle anticollision aspect; but impracticable, it mainly is that the time that bumps is too fast, and is too unexpected; in order to solve this difficult problem; brainstrust is made the car front bumper with the insurance cylinder that is full of air in the elastomeric material, utilizes air compression elasticity to cushion, and still this compression cylinder hits easily and bursts; with collision gas leakage; safety effect to protection chaufeur and passenger is not too obvious, and a kind of anti-impact bumper and for example also all is housed on the car of home market cash and carry sales or the lorry, but this bumper/spoiler is to be fixed on below the car chassis; nestle up the car front; too near from the driver, just in case crash, the driver is subjected to its evil earlier; sometimes you do not hit others; others wilfully hits with you, makes your anti-fat very, causes the accident.

The purpose of this utility model is that a kind of improved anti-collision device for automobile will be provided; it can be when automobile bumps; alleviate because of car to car impact produces violent bump vibrations and the life security and the property damage of bringing for driver or passenger, can protect life security and reduce traffic accident by actv..

The utility model is to realize like this, below car chassis or on the axletree or below a fixed body frame is housed, the push-and-pull piston is housed in the frame, piston links to each other with the low speed clockwise and anticlockwise motor, its objective is the release or the withdrawal that can allow this utility model accomplish to realize the full automatic control anti-impact bumper by electric energy, inside the push-and-pull piston, be equipped with and increase the weight of to push away spring, pushing away spring the inside is equipped with elastic force and pushes away post, pushing away post adorns mutually with anti-impact bumper, when vehicle collides, produce buffering by increasing the weight of to push away spring, impact force is absorbed by increasing the weight of to push away spring, thereby alleviate because of two cars collide the violent shock impacts that produces and give the driver or the personal casualty that the passenger brings and the loss of property, can be used with the used safety air bag of automobile again.

The utility model only needs to install additional a switch current distributor on the ignition lock of automobile; when the driver starts last retaining with key; control the low speed clockwise and anticlockwise motor afterwards for electricity by current distributor and push ahead the push-and-pull piston; together with increasing the weight of to push away spring; elastic force pushes away post and anti-impact bumper is released together; when shifting the summit onto, the top disconnects outage deeply concerned source, makes connecting rod push up connecting rod dieback point; if at this moment there is thing to bump against before the car; absorb hitting power by increasing the weight of to push away spring, reduce the impulsive contact force of automobile, become buffering; so can protect personnel's safety; when the driver will stop working, at this moment the counter-rotating ignition lock transferred negative pole power supply anyway by purpose made switch current distributor; cause motor to spur downwards; make push-and-pull piston and elastic force push rod regain the original place, (near automobile body) is suitable for car like this; micro-bus, being used for motorcoach or lorry can be motor and connecting rod; circuit is all dismantled; (dismounting automatic system); fixed its push-and-pull piston by piston location silk, made permanently effective being contained on the various vehicles of this device, more convenient effective.

Below with reference to accompanying drawing the utility model is described in further detail.

Section-drawing when Fig. 1 is the vertical release work of concrete structure of the present utility model.

Fig. 2 is side automatic drawing back figure of the present utility model.

Fig. 3 is an automobile side running chart of the present utility model.

Fig. 4 is automobile side parking automatic drawing back figure of the present utility model.

Fig. 5 is left right-hand part figure of the present utility model.

Fig. 6 be of the present utility model by piston location silk the structure diagram after fixing.

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6.

The fixed mount made from metal according to the bottom size of automobile (16), be secured in check screw (17) on the chassis or axletree thick stick of automobile, push-and-pull piston (5) is housed below fixed mount (16), piston pin (6) and connecting rod (7) are equipped with in push-and-pull piston (5) back, (7) connecting rod pin (8) and lever (9) are equipped with in the back, be used as power by low speed clockwise and anticlockwise motor (10), this motor (10) is powered by storage battery (15), through purpose made switch current distributor (14) distribution, this switch current distributor (14) and ignition lock (13) adapted, when ignition lock (13) instruction positive pole connects positive pole, when motor (10) will be released piston arrives connecting rod dead point (12), last top disconnects closes (11) outage, thereby allow motor (10) stall, when auto against arrives anti-impact bumper (1), elastic force pushes away post (2) and moves backward, increasing the weight of to push away spring (4) following of the effect that pushes away spring pin (3) cushions backward, head on fixed mount (16) by insuring top cover (20) when thrust is overweight, reach the buffering absorption and alleviate the violent bump of car to car impact generation and the loss of personal casualty or property.

Needs for convenience of driver's storage of cars or warehouse-in, with ignition lock (13) reversing, change power supply extreme direction, make connecting rod (7) to moving down, thereby push-and-pull piston (5) is pulled back, form anti-impact bumper like this near operator's compartment (21),, can also remove motor (10) or connecting rod (7) in order to promote the use of this device more easily, as shown in Figure 6, push-and-pull piston (5) is pushed away forward, tighten with piston location silk (19) and fix, do also very convenient and practical like this.If break anti-impact bumper (1), can pull down left and right sides thick stick body screw (18) and change, more convenient like this and durable.
