Abstract

The utility model discloses an automotive ignition switch key untaken-off alarm device, comprising an ignition switch, a power supply, an automotive door lock, a door control ceiling lamp switch and an alarm device. The alarm device is composed of a key insertion linked switch which is installed in an ignition switch lock body, a rotary switch linked with a door lock button, and a sounder. Two linked switches are connected in series, and the two linked switches are connected with an automotive trumpet and the power supply. When the ignition switch key is forgotten to take out, the automotive door is opened. When the door lock button is pressed down, the alarm device sends out the sound. A driver is reminded to take off the key on the ignition switch.

Description

Automotive ignition lock's key untake-off alarm device

The utility model relates to the warning device that does not take off when ignition key locks door in the pass behind a kind of automobile flameout.

Existing automobile door lock key and ignition key are shared, but often occur such problem in actual use: human pilot is forgotten because of having much to do and is taken off the key that is inserted on the ignition switch with on the car door lock, key is locked in the car, the safe-guard door lock of automobile reenters the obstruction personnel of driving in the car, thereby influences the normal use of vehicle.

In order to address this problem, common way is that human pilot must descend automobile-used key operated safe-guard door lock closed door.But under the situation that night, rainy day, car door are overhead higher, both hands are held article, close the inconvenience that locked door with key.

The purpose of this utility model provides a kind of warning device that prevents that ignition key from not taking off and car door is shut, it can open the door to get off and press door lock knob and prepare to close and to send alarm sound when locking door at human pilot, reminds human pilot to dial down the key that is inserted on the ignition switch.

The purpose of this utility model is achieved in that it is made up of ignition switch, power supply, automobile door lock, gate ceiling light switch and warning device, warning device is the rotary switch that is inserted linked switch and linked with door lock knob by the key that is installed in the ignition switch lock body, and sounder constitutes.Two linked switches are connected, and link with car horn, power supply.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.

Fig. 1 is the ignition switch structure synoptic diagram.

Fig. 2 is the rotary switch structure synoptic diagram.

Fig. 3 is an elementary diagram.

Referring to accompanying drawing, the utility model includes ignition switch K ₂, power supply 2, automobile door lock, gate ceiling light K switch ₁And warning device, warning device is to insert linked switch K by the key that is installed in the ignition switch lock body 1 ₂With with the rotary switch K of door lock knob interlock ₃, and the sounder formation, sounder adopts former car loudspeaker or hummer, and two linked switches are connected, and link with car horn, power supply 2, and power supply adopts former car power supply.

As can be seen from Figure 1, it is on ignition switch lock body 1 that key inserts linked switch, the axis direction that inserts along key 6 bores a circular hole, the insulating knockout pin 5 of packing in the hole, it can be free to slide along axis direction, push rod 5 one ends contact or disconnect with inserting key 6, and the other end passes lock body insulator foot 4 and contacts with the conductive reed 3 that resets or disconnect, and reset conductive reed 3 and conductive reed are fixed on the lock body insulator foot 4 by binding post.When key 6 inserted, the slip by insulating knockout pin 5 was in contact with one another reed, during taking-up, utilizes the elastic force of reed, disconnects voluntarily, realizes its switching function.

The rotary switch K of shown in Figure 2 and door lock knob interlock ₃Be to constitute by insulation crust 7, elastic copper sheet 8, binding post 9, on copper sheet 9, be pressed with a boss 10, when copper sheet is rotated can with two binding post conducting or disconnections, the centre hole axis of this interlock rotary switch is coaxial with the door lock axle, the rocking bar interlock of copper sheet and door lock safety button, shell is fixed on the car door lock by the door lock nut, thereby realizes its linked switch function.

Fig. 3 is an elementary diagram, and the main devices on this circuit has: power supply 2, sounder, ignition switch K ₂, rotary switch K ₃With gate ceiling light K switch ₁Whole unit Series have only when human pilot door to be opened and press door lock knob, and ignition key is forgotten and dialled following time, whole switch connections, and sounder sends alarm sound.This device is equally applicable to motor vehicles such as motorcycle.

Outstanding effect of the present utility model has following 2 points:

When 1, reminding driver is closed the door from car, take the key on the ignition switch away.

2, be convenient to promote, because this device can make improvements at the situation end that does not affect former car ignition switch structure and function, at the equipped linkage rotation switch of latch position, all the other can directly use former car parts, so simple in structure, easy for installation.
