Abstract

The utility model provides a car safety belt lock with a power switch. The power switch is fixed on the connecting steel plate of the car safety belt lock, the switch is provided with a fixing contact, a movable contact, a spring and a spring lifting movable contact, and the switch is connected between a power and a key electric door in series. When the head of the belt is inserted to the hole of the lock during tying the safety belt, the movable contact is contacted with the fixing contact under the action of the spring, the power is conducted, and when the head of the belt is pulled out during disconnecting the safety belt, the movable contact of the power switch makes the power disconnect under the action of the spring. Therefore, an engine can be started only after drivers tie the safety belt so as to avoid happening the safety hazard due to drivers not tying the safety belt.

Description

A kind of automotive safety of double source switch is with lock

It is with lock that the utility model relates to a kind of automotive safety, can be switched on or switched off the device of key electric switch power supply when fastening or unfastening one's seat-belt.

At present, normally used car belt and electric switch power supply are unrelated, and the personnel that drive, especially fresh driver owing to carelessness has been forgotten to fasten the safety belt, bring hidden danger for the personnel's that drive safety when driving.

For fear of these potential safety hazards, could fire an engine after the personnel of driving must be fastened one's safety belt, improve the personnel's that drive safety factor, this is practical to provide a kind of device that can be switched on or switched off the electric switch power supply when pinning or unfastening one's seat-belt.

The technical scheme that its technical matters that solves the utility model adopts is: pull at safety (prior art) with lock connection steel and set up two fixed screw holes, source switch is fixed on the connection steel plate, the push-button socket alignment of a hole of the switch spring bearing of unblanking, insert in the seat hole lower end of spring bearing, and switch series is connected between power supply and the key electric switch power lead.During operation, press safety red button with lock, the spring bearing of unblanking is to moving down, and button to the source switch of the lower end compressing source switch of spring bearing is in off-state, and safety strap also locates to untie state simultaneously.The source switch that essential conducting safety strap is locked before driving, ability electricity consumption door key fire an engine.When chaufeur took the lead safety to insert lockhole, in the interlock of mechanism for locking up, the spring bearing of unblanking will move up, and source switch is energized under the effect of spring.At this moment but the electricity consumption door key is with regard to fire an engine.

The beneficial effects of the utility model are: chaufeur will be fastened seat belts earlier before start a car, otherwise with regard to the fail to start driving engine, avoids the carelessness of chaufeur and the potential safety hazard that causes.

Below in conjunction with drawings and Examples the utility model progress is illustrated:

Fig. 1 is schematic circuit diagram of the present utility model.

Fig. 2 is the scheme drawing of safety (prior art) with lock.

Fig. 3 is the utility model source switch constructional drawing.

1 safety strap lock body, 2 source switchs, 3 automobile key switch, 4 actuating motors, 5 safety button with lock, 6 connect steel plate, 7 and unblank to play Wang Zhu, 8 source switch fixed screw holes, 9 power switch buttons, 10 push-button socket holes, 11 springs, 12 moving contacts, 13 fixed contacts, 14 screw holes, 15 binding posts, 16 binding posts among the figure

The specific embodiment:

The connection steel plate (6) of safety (prior art) with lock is set up two fixed orifices (8) in Fig. 2, source switch among Fig. 3 (2) is fixed in the above, the spring bearing (7) of unblanking is aimed in the seat hole (10) of shift knob, insert in the seat hole (10) lower end of spring bearing (7), binding post (15) on the source switch (2) connects power supply, binding post 16 connects key switch (3), when before driving safety being taken the lead to insert lockhole, in the interlock of mechanism for locking up, spring bearing (7) will move up, power switch button (9) is under the effect of spring (11), move up, be fixed on the moving contact (12) on the button (9), be moved upward to fixed contact (13) thereupon and contact, key electric switch power connection, simultaneously safety strap is also located the state fastened.Chaufeur is with regard to available electric switch key start a car.

After the parking, the online structure safety of button (5) of pressing safety strap drives the spring bearing (7) of unblanking and moves down to lower compression power switch button (9), be fixed on button (9) go up moving contact (12) thereupon downwards and fixed contact (13) break away to power supply and disconnect, at this moment safety strap is in the state of untiing, as need start a car once more, just must fasten one's safety belt, thus the purpose that must fasten seat belts before realizing driving.
