Abstract
The present invention relates to a device of a lap-belt which can automatically unfasten a buckle when encountering with water. The structure of the present invention includes a bracket and a manually unfastening buckle. A motor is connected with a mandril by gears; the mandril is contacted and connected with a deflector rod, another end of which is contacted and connected with a locking rod inside a L-shaped slideway; a push pedal is arranged at the position for a life belt to inserting the buckle; the push pedal is in linkage connection with a start switch by a reversing yoke; the start switch communicates with an electrical source of an operation amplifying circuit; a water induction sensor is output to an input end of the operation amplifying circuit, and an output end of the operation amplifying circuit communicates with the motor. The device solves the defect that when the automobile falls into the river, the driver in fluster forgets unfastening or can not touch the buckle or other unknown reasons cause that the life belt can not be unfastened in time, and the driver can not escape from the automobile and is drowned inside the automobile. The present invention only need changing the buckle of the life belt and putting an electrical wire through, then the life belt can promptly and automatically unfasten for a safe escape, when the automobile falls into the river, the lake and the water ditch. The present invention has simple structure and reliable electronic circuit.
Description
Technical field
The present invention relates to a kind of automobile safety belt device, particularly a kind of car belt is the snap close automatic releasing device when meeting water.
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 invention, 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 escape from automobile rapidly, but owing to flurried and accident occur in moment, steerman can't manually be unfastened one's seat-belt, and particularly automobile crashes into the korneforos, navigating mate has been forgotten to open or touch less than snap close or other not bright reasons among in a hurry makes safety strap fail in time to open, fixed onboard by safety strap, can't escape from automobile, be drowned in automobile.
Summary of the invention
Purpose of the present invention just is to overcome above-mentioned defective, designs a kind of device that water can be freed safety strap automatically of meeting.
Technical scheme of the present invention is:
Automobile lap-belt automatic water-encountering disconnection device, comprise support, manually trip, it is characterized in that electrical motor connects push rod by gear, 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 is connected by reverse lever and starting switch, and starting switch is communicated with the power supply of operational amplification circuit, the water induction sensor exports the input end of operational amplification circuit to, and operational amplification circuit output is communicated with electrical motor.
Advantage of the present invention and effect are to keep former car belt latching system substantially, only need change safety belt lock catch during installation, connect a wire, and when automobile dropped in river, lake, the ditch, safety strap was untied safety at once automatically and fled for life when automobile is met water.
The present invention is simple in structure, and electronic circuit is 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, push pedal 16 is connected by reverse lever 14 and starting switch 17, starting switch 17 is communicated with the power supply of operational amplification circuit 19, operational amplification circuit 19 outputs connect electrical motor 10, and two electrodes of water induction sensor 20 are communicated with operational amplification circuit 19 input ends.
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, simultaneously because safety strap eye-splice 7 promotes push pedal 16, push pedal 16 promotes reverse lever 14, when reverse lever 14 is connected starting switch 17 (being K3 among Fig. 6) downwards, make starting switch 17 closures, thereby connect the power supply of operational amplification circuit 19.
At this moment, the use of safety strap and the using method of original safety strap are just the same, free safety strap if desired, only need press and manually trip 1, and then support 2 is ejected in safety strap eye-splice 7 under the effect of spring 6 and push pedal 16, thereby opens safety strap.
When vehicle crashes into the korneforos, two electrodes of water induction sensor 20 are by the water conducting, make the output of operational amplification circuit 19 reverse this moment, electrical motor 10 starts, electrical motor 10 is by gear 11,12,15,13 drive push rod 9 left, pushing tow driving lever 8, when promoting driving lever 8, driving lever 8 breaks away from the contact of reset switch 18, reset switch 18 is switched on (being K2 among Fig. 6), and driving lever 8 is lever constructions, and 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 as shown in Figure 3.
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 again, but this moment, reset switch 18 still was in conducting state, so electrical motor 10 continues rotation, reverse lever 14 resets gear 12 and makes push rod 9 begin to retreat as Fig. 4 and shows simultaneously, when driving lever 8 is got back to initial position, reset switch 18 disconnects as Fig. 5, and 19 of operational amplification circuits restPose.
