Abstract
The utility model relates to a hand-braking safety device for an automobile, which is composed of a hand brake, a travel switch, a battery cell and a door lock, wherein, a circuit is composed of the travel switch, the battery cell and the door lock; when the hand brake is not pulled, the travel switch is closed, and the door lock is closed; thus, the utility model can avoid that a driver gets off when the hand brake is not pulled, preventing accidents from happening.
Description
The utility model relates to a kind of automobile hand brake safety device.
Automobile hand brake is a kind of device of locking wheel behind the automobile flameout.According to the vehicle drive regulation, the driver must be with the hand braking latched position that is put into behind switch-off.But the driver forgets the handle drg sometimes, particularly works as car and is parked on the acclive position, will lead to a disaster from line slip because of automobile.
The patent that Decree of Patent Office of China CN2223704Y name is called " automobile hand brake safety alarm device " provides a kind of and has reminded the chaufeur back device of tension hand lever in time that stops in the language alarm mode, and it connects post travel switch, storage battery and annunciator by the ignition lock of setting up a binding post, four and forms.Because of annunciator adopts phonetic alarm, if the annunciator et out of order, the driver might forget and draw drg that unavoidable accident takes place.
The purpose of this utility model provides a kind of automobile hand brake safety device, can avoid occurring driver's situation that drg driver or member just can get off of not shaking hands.
The purpose of this utility model is achieved in that the automobile hand brake safety device is made up of hand brake, travel switch, storage battery, door lock.
Door lock is made up of magnet coil, lock pin and retracing spring, and inserting a T sections core in magnet coil is lock pin, on an end of lock pin retracing spring is installed, and bores a lock hole on pairing door case of lock pin head and car door.Hand brake is connected with travel switch, and travel switch, storage battery and door lock constitute a circuit.When not shaking hands drg, the travel switch closure, electric current produces magnetic field after by coil, and magnetic field promotes iron core and inserts lock hole, doors locked.When the driver locked hand brake, travel switch was opened, and coil current is cut off, and magnetic field disappears, and iron core withdraws from lock hole under the effect of retracing spring, car door opening.
The utility model has the advantages that hand brake and door lock oppositely link, hand braking locking, door lock is opened, otherwise then closes.The driver with the hand brake locking, just can't not open the door and get off, and has avoided the generation of accident.
Accompanying drawing 1 is the circuit block diagram of the utility model automobile hand brake safety device
Accompanying drawing 2 is the utility model automobile hand brake safety device front elevations
The present invention is further detailed explanation below in conjunction with accompanying drawing:
The utility model automobile hand brake safety device is made up of hand brake 1, travel switch 3, storage battery 5 and door lock 6, and door lock 6 is made up of magnet coil 10, lock pin 12 and retracing spring 11.A coil 10 is installed on automobile door frame 9, is inserted a T sections core in coil, promptly lock pin 12, and retracing spring 11 is installed on lock pin, bore a through hole on pairing door case 9 of lock pin head and car door 7, and promptly lock hole 8.One stroke switch 3 is installed near the car body the hand brake 1, and hand brake is connected with steel wire 2 with travel switch, and travel switch, automobile storage battery and coil form a circuit.Behind automobile flameout, driver's tighten hand brake 1, steel wire draws back travel switch, and circuit is for off state, and the electric current of coil 4 is cut off, and magnetic field disappears, and lock pin 12 withdraws from lock hole 8 under the effect of retracing spring 11, and door lock is opened.When the driver had forgotten tighten hand brake, travel switch 3 effect of retracing spring within it was down closed, and electric current flows to coil 10 by switch, produces magnetic field, and under the effect in magnetic field, lock pin 12 inserts calm hole 8, and car door 7 is locked, under the driver not car.
Door lock of the present utility model can a plurality ofly be connected, and links to each other with storage battery with travel switch.
Use the utility model automobile hand brake safety device can avoid driver's drg of not shaking hands just to get off, prevent the generation of accident.
