Abstract

The utility model belongs to a safety brake for motor vehicle, in particular to an emergency brake device which is used for braking and decreasing the collision impact when the motor vehicle meets with the obstacle. The utility model is produced by the originally bumper being added with wider movable bumpers; when the motor vehicle meets with the obstacle, the emergency brake device uses the bumpers to push the piston-rods to contact with the contactor, the magnetic force is produced by connecting the electromagnetic circuit, which causes the electromagnet to pull the brake pump, so the aim of the auto brake is achieved; besides, a damper spring and a rubber packing are arranged between two bumpers, which avoids of the malignant traffic accident.

Description

Safety brake for motor vehicle

The utility model belongs to a kind of brake device for car, braking and subdue the insurance brake equipment of collision impact power when particularly a kind of automobile runs into obstacle.

In the common traffic accident, automobile directly clashes into object (as house, trees, cliff) or collision is uncommon, but accident generation in a single day, its result is quite serious.Trace it to its cause, except that minority because the brake system fault causes, cause by manual handling owing to brake system is moving mostly, as tired driver excessively or driving a car under the influence of alcohol, the speed of a motor vehicle is crossed under the high situation and the device of automatic brake and buffering after the auto against object is not installed, can not in time brake or brake to come into force at once, thereby cause heavy losses even harm personal safety.Therefore, the moving guarantee driving safety fully of existing manual brake system.

The purpose of this utility model provides a kind of motor insurance brake equipment, can self-actuating brake under the situation that it is not braked during object on auto against, and can slow down the impulsive force of auto against.

Its solution is: in original bumper/spoiler front, install a movable bumper/spoiler additional, a piston rod is respectively loaded onto on two limits about it, and they communicate with contactless switch, forms the switch of an electromagnetism circuit, when automobile knocks object, bumper/spoiler is length of spring compressed, and piston rod advanced contacts switch on contactless switch, produce magnetic force and make electromagnet pulling master cylinder, automobile is stopped thereby drive whole brake system action.Rubber buffer also is housed on former bumper/spoiler, between two bumper/spoilers recoil spring is housed, to subdue the impulsive force of auto against.

Accompanying drawing has been described an embodiment of the present utility model, and it and pneumatic brake matched with devices are used, in fact also can with the supporting use of the brake equipment of fluid pressure type or other pressure types.Fig. 1 is this device overall schematic, and Fig. 2 is the electromagnetism conspectus, is described further below in conjunction with accompanying drawing:

1 is movable bumper/spoiler among Fig. 1, its limit broad, can accept the impact that direction shown in the arrow is come before the thick stick from figure, piston rod 6 usefulness permanent seats are connected on the bumper/spoiler, and as the upholder of bumper/spoiler 1, it is a guide rod, the end is spherical, former bumper/spoiler 4 is passed by conduit 5 in the centre, about on the bumper/spoiler, a piston rod and contactless switch 7 are housed respectively, can both compression spring 2 when stressed with assurance thick stick 1 from all angles, and promote piston rod and contact with the contact of contactless switch, make circuit 11 conductings, produce very strong magnetic force, at this moment electromagnet 12 adhesives, the backward stick action of drive master cylinder 13, pressure gas arrow direction from figure flows into wheel cylinder and makes the front and back wheel braking.

2 is recoil springs among the figure, and being installed on the former bumper/spoiler 4 is that its effect has two: one between two bumper/spoilers, buffering inertial impaction power, and the 2nd, make bumper/spoiler and piston rod under normal circumstances keep original position or return after the releasing accident; The 3rd, the buffer rubber gasket of certain thickness and elastic force is arranged, be installed on the former bumper/spoiler; The 8th, radiator; The 9th, automotive frame; The 10th, driving engine; The 14th, original artificial brake pedal; The 15th, why former master brake cylinder acts on respectively with two master brake cylinder, is the action in order to make it to be independent of each other separately; The 16th, pressure container is used air tank in the present embodiment.In addition, contactless switch is made of the guide rod of a contact-carrying and shell and pull back spring, and this spring guarantees that contact contacts and make the guide rod return with piston rod good when crashing; Piston rod also is a conductor; In the electromagnetic circuit scheme drawing of Fig. 2, a normally closed switch 1a is arranged, amperemeter/ammtr 2a, buzzer phone or read out instrument 3a and insurance 4a, thermally dependent resistor 5a and diode 6a, after the circuit connection work, buzzer phone generation sound or shows signal remind chaufeur after automobile stops, disconnect normally closed switch rapidly, the reason work-hours is long and burn out to guarantee the electromagnet circuit, if do not cut off the electricity supply, when the electromagnet winding temperature surpasses 70 ℃, the insurance circuit that thermally dependent resistor and diode and insurance are formed promptly produces reaction, blown fuse is cut off the electricity supply automatically, thereby guarantees that the electromagnetism circuit can not burn, simultaneously, also only after cut-off switch is cut off the electricity supply, could eliminate braking, make the automobile reversing that starts to walk again.It should be noted, except should be on the correct position of former bumper/spoiler perforate so that install the piston conduit, also former bumper/spoiler should be moved be contained in and be on the conplane crossbeam, and will draw and link up with the below that moves to bumper/spoiler with louver.

After automobile is installed this device, will produce following effect: when automobile meets barrier and driver when having little time to brake, its can automatic brake; Automobile still continues to travel with very big inertia force behind the clobber when having implemented to brake in short distance, except its energy automatic brake, buffer spring and rubber blanket can make impact and reaction force thereof subdue, make automobile further obtain buffering, stop under brake force and the cushioning effect rather than under the reaction in strikes obstacles, thereby avoiding the generation of the great serious accident of car crash. This device is easy to manufacture, and is easy for installation, need change hardly and can install existing automobile.
