Description

Multi-functional anti-theft lock for automobile

The utility model belongs to the automotive accessory field, particularly a kind ofly can pin automotive ignition system simultaneously, the multifunction anti-theft lock of cover before storage battery and the car in the car.

Existing alarms and security systems for automobiles is to adopt special lockset that bearing circle and gear lever lock are fixed on structure on the car body mostly, though it is easy to be inexpensive, but the high burglar that plants for unblanking can't take precautions against, and the premium-quality satellite positioning recognition system anti-joyride device that has also reaches the price that can popularize far away, therefore it is a kind of antitheft reliable to press for design, cheap, as to be easy to install onboard anti-joyride device.

It is a kind of cheap, easy for installation that the purpose of this utility model will provide exactly, can pin ignition device simultaneously, the anti-theft column lock of the dependable performance of storage battery and car protecgulum.

The purpose of this utility model is realized by following proposal: multi-functional anti-theft lock for automobile, include lock control mechanism 1, the lock head component 2 and the anti-theft remote controller that match, described lock head component 2 is installed on the preceding cover inwall of automobile, is made up of tapered end bar 21, lockhole cover of dust 22, holddown spring 23, installation tube 24, the fastening block 25 that connects with loam cake and coupling nut 27; Described lock control mechanism 1 is installed in vehicle body sidewall in the automobile cover, has the lockhole 126 that inserts for tapered end in the mechanism, its installation site keeps lockhole corresponding with tapered end, in the shell 111 of latch mechanism 1, dc micro-motor 11 is housed, by retarder 12 driven gears 13 on the support 19 of being installed in that link with it, tooth bar 14 makes dead bolt 15 translations by pipe link 17, the control strip 132 that is installed in the micro-switch 16 on the removable and fastening tooth bar baffle plate 18 of tooth bar top links with pitman, its lead-in wire 114 is connected to high-tension coil or is connected to storage battery, and mechanism's loam cake 120 is screwed on shell 111.Lock control mechanism and the lock head component that matches have two covers, are installed in respectively on the front truck cover and arranged on left and right sides inwall.The lead-in wire (14) of the micro-switch of two cover lock control mechanism is connected to high-tension coil and storage battery respectively.

Accompanying drawing 1 is the utility model installation site scheme drawing;

Accompanying drawing 2 is structural representations of the present utility model;

Accompanying drawing 3 is section-drawings of accompanying drawing 2;

Accompanying drawing 4 is the utility model dead bolt fundamental diagrams;

Accompanying drawing 5 is micro-switch control circuit schematic diagrams.

Below in conjunction with description of drawings embodiment, cover 3 inwalls before lock head component 2 is installed in as shown in Figures 1 to 4, the lock control mechanism 1 of hole with lock and dead bolt is installed in vehicle body sidewall in this preceding cover, and the tapered end 21 of the two is corresponding with lockhole 126 positions to coincide.By to circuit control lock car or unblank, control circuit part can link with commercially available any anti-theft remote controller (but also self-organizing system).In the time of on controlling Door Lock with remote controller, the electronic circuit of this device of signal triggering by Car Burglar Alarm output, again by drive motor 11 power supplies of lock electrical equipment in this mechanism, driving dead bolt 15 by gear 13-gear 14-moves to lockhole 126 directions, dead bolt 15 will be fixed on the cover after about 2 seconds lock and tapered end 21 are locked, and electronic circuit also cuts off the power supply simultaneously.Before dead bolt 15 is reached home, tooth bar 14 overwhelms micro-switch 16 control strips 132 with the pipe link 17 of dead bolt 15, cause the relay coil dead electricity of control ignition system switching and control storage battery or other electrical equipment and discharge, thereby cut off ignition system and storage battery or other electrical equipment path, as shown in Figure 5, micro-switch is connected, and J coil losing electricity releasing activity contact separates with black contact, cut off ignition power, reached the purpose of outage lock car.When engine operation, this device dead electricity, the reason mistake is not bumped remote controller key and is caused parking.

The utility model since will all install (comprising the circuit control part) all be contained in before in the cover, except that the car owner, if other people will open, and preceding cover is very difficult, thereby has a multiple function, it is very reliable to work, and apparatus structure is firm, and makes advantage easy to maintenance.
