Abstract
The utility model relates to an automatic braking device for an automobile, which is formed by that the present pull rod of the braking master pump of the automobile is connected with an isolator composed of a return spring and the connective bar of the pull rod of the braking master pump in series; a special electromagnetic switch is arranged beside a sound insulator or a braking pedal; after energized, the special electromagnetic switch generates action of force on the braking master pump, and then the special electromagnetic switch is locked; locks used for locking the braking are arranged on each switch; when the automobile has an accident, the electromagnetic switches are energized; moving punches in the switches apply force on the braking master pump via the connective bar of the pull rod of the braking master pump or the braking pedal, and consequently the automobile is automatically braked; simultaneously, the lock acts; the electromagnetic switches are switched off; the automobile is still in the state of automatic braking.
Description
The utility model relates to a kind of electric automatization, particularly a kind of have in case of emergency need not artificial and can make the device of automobile automatic brake.
When automobile when crashing, the automobilist often loses thinking, control ability, this moment, most broken-down vehicles also can continue to travel, and the car that causes the accident is not to go out highway to cause outward and overturn and cause passenger's injures and deaths to continue exactly to clash into other vehicles or pedestrians and cause second accident.For fear of above-mentioned second accident, I have invented a kind of " automatic brake for vehicles " by name, and applied for patent to Patent Office of the People's Republic of China on August 9th, 1, application number is: 951093282, and its design-calculated scheme is: string is loaded onto decelostat in pushing away between automobile brake general pump and brake pedal (drawing) bar.Brake is by locking column, the energising back produces the coil in magnetic field, fixing suction nozzle, the electromagnetism push rod, compositions such as movable ram, when automobile meets accident, can make the automatic contactor action of coil electricity, making in the coil that produces magnetic field has electric current to pass through, this moment movable ram, fixedly suction nozzle is magnetized and attracts each other, movable ram is under the attraction of fixing suction nozzle, push away the motion of (drawing) bar by the electromagnetism push rod, and make master cylinder action back automobile autobrake, reached self-stopping purpose, but by practice, I find that " automatic brake for vehicles " also exists following deficiency: first is because decelostat is to go here and there to be contained in pushing away between master cylinder and the brake pedal (drawing) bar, and decelostat just takes regular exercise together in company with the brake push rod, makes the joint of coil in the brake or lead electric leakage cause danger easily; Second is the restriction that the suction of this kind decelostat is subjected to winding volume, and when automobile met accident, braking effect was undesirable; Thirdly be that this kind decelostat is not provided with pull back spring, during normal brake application, brake resets unhappy, and influence is quickened again.
The purpose of this utility model provides a kind of self brake device for car, makes automobile when meeting accident, not only make automobile energy automatic brake, avoid the generation of second accident, and can make that electromagnetic switch is static with respect to automobile when normal braking, brake resets very fast during normal brake application.
The purpose of the utility model work is to realize like this, in self brake device for car, comprise: brake push rod, pull bar, master cylinder, wheel cylinder etc., it is characterized in that: string is loaded onto an isolator in the master cylinder of vapour braking vehicle and the pull bar between the brake pedal, the isolator pull back spring that the brake return is used is housed in the isolator, the master cylinder pull bar pitman that master cylinder pull bar and brake pedal pull bar are isolated also is housed in the isolator when meeting accident the automobile automatic brake; On the isolator next door two circuit being housed is parallel connection method, and the energising back produces the electromagnetic switch of power effect to master cylinder; Passing through the brake lever arm-tie directly produces the power effect again to master cylinder to the brake pedal rod application of force electromagnetic switch with the other energising back of loading onto of the braking automobile pedal of oil brake; An electromagnetic switch action back outage at once is housed on each electromagnetic switch, and automobile also is in the lock for lock brake of braking state; Confession locking arm-tie usefulness and diameter are arranged than the little circular hole of brake lever arm-tie fixed orifice diameter on the movable suction nozzle of electromagnetic switch; Producing has one to make and be tightened in push rod in the movable suction nozzle with non-permeable material in the electromagnetic switch of thrust.
Working process of the present utility model is as follows, when automobile crashes, be contained in the automatic contactor action on bumper/spoiler and the operator's compartment, make the coil of the electromagnetic switch in the self brake device for car have electric current to pass through, fixedly suction nozzle and movable suction nozzle in the electromagnetic switch are magnetized and attract each other, movable suction nozzle applies an application force to master cylinder, thereby make the automobile automatic brake, when this movable suction nozzle moves to range, the lock action, this moment, safety fuse cutout blew, perhaps other reasons outage, and automobile also is in braking state.
The detailed operation principle of concrete structure of the present utility model is described below in conjunction with accompanying drawing.
