The utility model solves the defects that the taxi driver cannot unfasten the safety belt in time or cannot unfasten the safety belt because of hurry and tension under the special situation that taxi driver is robbed or the taxi is burning etc. The utility model has the advantages that the utility model basically retains the lock catch device of the original automobile safety belt, the only requirement is to replace the safety belt lock catch during installation and to connect three wires, the utility model can still ensure the automatic unfastening of the safety belt simultaneously while the automobile door is opened under the condition that the automobile keeps unmoved, thereby to gain valuable time for the driver under the special situation.

Description

Automatic releasing device of automobile safety belt

Technical field

The utility model relates to a kind of automobile safety belt device, particularly a kind of snap close automatic releasing device of car belt.

Background technology

Since the invention car belt, it is bringing into play important safety effect in car accedent, becomes the passive type safety apparatus of automobile indispensability already.

Before the present utility model, the snap close of various car belts is all manually freed, no matter vehicle, class, brand and price how, do not have the safety strap of a automobile to thread off automatically.When people's steering vehicle, all must fasten one's safety belt according to the traffic law regulation, unfasten one's seat-belt when getting off, walk out automobile then.But under some special case, people need walk out automobile rapidly, and but the safety strap that is hitched ties down, and must later unfasten one's seat-belt and just can walk out automobile.Meet with to plunder as taxi-man, often open the door when fleeing from because of having little time to free safety strap the driver, feasible chaufeur of fleeing from is fully if having time controled oneself because of safety strap and is killed or injures in car; And for example, run in the automobile and catch fire, the driver forgets among in a great rush and unfastens one's seat-belt, and can't flee from or in a great rush, in the anxiety, can't unfasten one's seat-belt all the time, and be scorched to death or burn in automobile.

Summary of the invention

The purpose of this utility model just is to overcome above-mentioned defective, designs a kind of device that can free safety strap automatically.

The technical solution of the utility model is:

Automatic releasing device of automobile safety belt, comprise support, manually trip, its major technique is characterised in that electrical motor connects push rod by gear, and push rod is connected with the driving lever contact, and the driving lever other end is connected with the locking bar contact, locking bar is in L shaped slideway, push pedal is arranged on the safety strap eye-splice position, and push pedal and starting switch are connected, and starting switch is communicated with microcontroller power supply, micro controller system is communicated with electrical motor, and door lamp switch is communicated with the input end of micro controller system.

Advantage of the present utility model and effect are to keep former car belt latching system substantially, only need change safety belt lock catch during installation, connect three wires.Automobile is opened car door as long as under actionless situation, and apparatus of the present invention will be unfastened one's seat-belt simultaneously automatically, and the driver must not use manually to trip and just can walk out car door, for the driver wins the quality time under special case.

The utility model is simple in structure, and electronic circuit is provided with comprehensively, can respond to from impact or vibrations on any one direction of three dimensional space, to prevent the kickoff mechanism misoperation, makes it more reliable.

The specific embodiment

Shown in Fig. 1,2,3,4,5,6:

On support 2, have and manually trip 1, the position or the groove that also have safety strap eye-splice 7 to insert also are provided with a L shaped slideway 3 in support 2, and locking bar 4 is in L shaped slideway 3, and these are that prior art has.Electrical motor 10 connects push rod 9 by

gear

11,12,15,13, and push rod 9 is connected with driving lever 8 contacts, and driving lever 8 is connected with reset switch 18 contacts, and driving lever 8 other ends are connected with locking bar 4 contacts; Push pedal 16 is arranged on the position of safety strap eye-splice 7 insertions, and push pedal 16 is connected by reverse lever 14 and starting switch 17, and starting switch 17 is communicated with micro controller systems 19, and micro controller system 19 is communicated with electrical motors 10, and door lamp switch 20 is communicated with the input end of micro controller system 19.Switch comprises starting switch 17, reset switch 18, and reverse lever 14 is connected starting switch 17 downwards, and reverse lever 14 upwards makes push rod 9 counter motions of rising disconnect up to reset switch 18, and electrical motor 10 shuts down.

When shutting automotive door, door lamp switch 20 on the automobile disconnects, when the driver inserts the groove of supports 2 or position with safety strap eye-splice 7, safety strap eye-splice 7 is caught on by the buckle on the support 25, because safety strap eye-splice 7 promotes push pedal 16, push pedal 16 promotes reverse lever 14 simultaneously, during reverse lever 14 contact start switches 17 (being K3 among Fig. 6), make starting switch 17 closures, connect the power supply of micro controller system 19, micro controller system 19 begins to retrieve the signal of door lamp switch 20.

When vehicle stationary (parking), the driver opens automotive door, door lamp switch 20 is just connected, pass to micro controller system 19 by input end, micro controller system 19 just sends instruction, actuating motor 10, electrical motor 10 is by

gear

11,12,15,13 drive push rod 9 pushes up pushing tow driving lever 8 left, when promoting driving lever 8, driving lever 8 breaks away from the contact of reset switch 18, and reset switch 18 is switched on (being K2 among Fig. 6), and driving lever 8 is lever constructions, its other end moves down, force locking bar 4 from the top down along L shaped slideway 3, from left to right move, roll into unlocked position, thereby the buckle 5 that catches on safety strap eye-splice 7 is lifted to the right, discharge safety strap eye-splice 7, support 2 is ejected in safety strap eye-splice 7 under the effect of spring 6 and push pedal 16, thereby opens safety strap such as Fig. 3,1 does not open safety strap eye-splice 7 and must not press in addition manually to trip with hand.

When automobile in the process of moving, if accident is opened car door, will cause safety strap eye-splice 7 to break away from supports 2, thereby open safety strap.In order to address this problem, acceleration pick-up 22 is set on the circuit of micro controller system 19, and is three-dimensional, make it to respond to the acceleration/accel on any direction.When automobile is bumping or produces under the situation such as jolt, even car door is opened, micro controller system 19 detects above-mentioned signal (being that automobile does not stop), then can not connect electrical motor 10 all the time, electrical motor 10 can not move, and then safety strap eye-splice 7 is just caught on by buckle 5 all the time, can't break away from support 2, thereby make automatic releasing device produce misoperation, guarantee safety at the automobile Shi Buhui that bumps or jolt.

In case safety strap eye-splice 7 breaks away from support 2, then push pedal 16 and reverse lever 14 reset, make starting switch 17 be in closed condition such as Fig. 4 again, but this moment, reset switch 18 still was in conducting state, so electrical motor continues rotation, reverse lever 14 resets gear 12 and makes push rod 9 begin to retreat as Fig. 4 and shows simultaneously, and reset switch 18 disconnects as Fig. 5, and 19 of micro controller systems restPose.

If the driver does not open car door, unfasten one's seat-belt, then can press and manually trip 1, make locking bar 4 be rolled into unlocked position along L shaped slideway 3, force buckle 5 to discharge safety strap eye-splice 7, safety strap eye-splice 7 still can break away from support 2, thereby opens safety strap.
