Description

Electronic automobile door child lock

The utility model relates to a kind of electronic automobile door child lock.

Existing automobile, particularly household small-size automobile (car) except that the car door external lock is installed, all are equipped with child lock in car door on its car door.The effect of child lock is that car door can't be opened internally when its locking, can only could be with car door opening by the outside.The purpose of design of child lock is to prevent that children from causing danger when running car or without the guardian agrees to open car door without authorization.Along with the development of control technology, at present automobile various automatons such as automobile door lock central control unit etc. quite general, but with regard to child lock because the particularity of its installation site, there all do not have electronic automobile door child to lock out to be existing always.

The purpose of this utility model just provides a kind of electronic automobile door child lock to overcome the deficiencies in the prior art.

The purpose of this utility model is achieved in that electric lock engine and the child lock for automobile pull bar of original lock of utilizing existing automobile door lock central control unit, it is characterized in that on the lock pull bar, slide block being set, fluted on the slide block, in electric lock engine end rigidity fixture block is set, chute is arranged on the fixture block, slide block place in the chute of fixture block and the groove on the slide block towards the chute bottom of fixture block.

So-called electronic automobile door child lock is characterized in that slide block and fixture block made by aluminium alloys or engineering plastics.

The course of work of the present utility model is: when opening or closing child lock, the lock pull bar of child lock can axially-movable, thereby the lock pull bar can drive slide block and moves in the chute of fixture block.When child lock was in the unlatching shape, slide block can move along chute in the chute of fixture block; When needs are closed child lock, make the action of electric lock engine by the automobile door lock central control unit, thereby driving fixture block moves, fixture block is fallen in the groove of slide block, because the electric lock engine is fixed on the car door, therefore by slide block the lock pull bar is fixed and can not axially-movable, thereby can't be opened child lock, also just can't in car, open car door.The utlity model has simple in structurely, safe and reliable, can make all various door locks of automotive door realize central electric control operation.

Below by embodiment, in conjunction with the accompanying drawings the utility model is further described.

Fig. 1 is a kind of example structure schematic diagram of the utility model;

Fig. 2 is an embodiment slide block structure schematic diagram;

Fig. 3 is an embodiment fixture block structural representation.

Among the figure, 1. be slide block, 2. for fixture block, 3. for groove, 4. for chute, 5. for the electric lock engine, 6. for the lock pull bar.Wherein slide block 1., 2. fixture block is made with engineering plastics.6. slide block is set 1. at the lock pull bar on, 3. 1. slide block gone up fluted, the electric lock engine end 5. rigidity fixture block is set 2., 4. fixture block has chute on 2., slide block 1. place fixture block chute 2. 4. in and the groove 1. gone up of slide block 3. towards fixture block chute 2. 4. bottom.When opening or closing child lock, the lock pull bar of child lock 6. can axially-movable, thereby 6. the lock pull bar can drive slide block and 1. move in 4. at fixture block chute 2..When child lock is in when opening shape, 4. 1. slide block can move along chute in 4. at fixture block chute 2.; When needs are closed child lock, by the automobile door lock central control unit 5. the electric lock engine is moved, thereby driving fixture block 2. moves, make fixture block 2. fall into slide block groove 1. 3. in, because 5. the electric lock engine is fixed on the car door, therefore 1. make the lock pull bar 6. fixing and can not axially-movable by slide block, thereby can't open child lock, also just can't in car, open car door.
