Description

Remote-controlled automobile door lock

The utility model relates to a kind of remote-controlled automobile door lock, specifically be a kind of can remote-control car door lock forced locking device.

Invented at present and can carry out central controlled automobile door lock each door lock of automobile.But because building block is many, thereby structure is comparatively complicated, and as a kind of automotive door electronic lock that the patent CN2120157U that announces on the Chinese patent communique provides, its drive disk assembly needs three grades to slow down and clutch, and is comparatively cumbersome.

The purpose of this utility model is to provide a kind of building block few, and is simple in structure easy for installation, compatible good, applicable to the remote-controlled automobile door lock of all types of automobiles.

This door lock comprises: a box body, and a lid, a direct current micro machine has fastened a gear, two deceleration column generating gears, a tooth bar balladeur train, a cone pulley support, a dust cover and circuit control box on its axle; It is characterized in that: the direct current micromotor axis normal is placed in tooth bar sledge movements direction in (1) box body, the lid, (2) two deceleration column generating gears are measure-alike, (3) the both sides tooth bar balladeur train that has a gathering sill is done rectilinear motion by the turriform gear driven, and (4) are with bellows between tooth bar balladeur train and box body; Circuit control box is by power regulator, pulse trigger, and the trigger delay circuit promotes circuit, executive circuit, holding circuit is formed.

The utility model has the advantages that parts are few, simple in structure, cost is low, and it is easy for installation not influence primary car structure, can with remote control on the market and other automatic device compatibility, applicable to all kinds of automobile door locks.

Accompanying drawing 1 is the utility model structural representation, and accompanying drawing 2 is a lateral view.

Wherein: 1, direct current micromotor; 2, gear; 3, turriform gear I; 4, box body; 5, turriform gear II; 6, dust cover; 7, the tooth bar balladeur train; 8, lid; 9, the cone pulley support.

The utility model is described in further detail below in conjunction with accompanying drawing:

At box body 4 and lid 8 built-in direct current micro machines 1, when control box provides a delay pulse signal, motor 1 is gone up fixing gear 2 with it and is rotated, drive double reduction turriform gear 3,5 and do rectilinear motion by cone pulley II driven gear balladeur train 7, thereby the action of driving automobile first wife mechanical door lock realizes opening/locking door function.

In the utility model, direct current micromotor axis direction and tooth bar sledge movements direction are perpendicular, adopt two identical turriform gears to carry out double reduction simultaneously, two cone pulleys are individually fixed on box body locating slot and the cone pulley support, install easy to adjust, simple in structure, realized the most quickly and easily by former gyration to straight-line conversion.Because two turriform gear size are identical, thereby make overall dimensions be kept to minimum, it is good to have saved the installing space compatibility, help installing, between tooth bar balladeur train and lock box, be with bellows in addition, prevent that effectively dust, foreign matter from going in, improved the running environment of remote-controlled automobile door lock, improved durability, increased reliability, had gathering sill in tooth bar balladeur train both sides simultaneously and carry out rectilinear motion along the guide pad on box body, the lid to guarantee the tooth bar balladeur train.

Circuit control box is by power regulator, pulse trigger, and the trigger delay circuit promotes circuit, executive circuit, holding circuit is formed.

Power supply stabilization circuit is made up of R13, E6, Z1, D3, E5, and automobile+12V power supply is by the input of P8 mouth, and through E5 filtering, D3 is a reverse-phase protection, through the R13 current limliting, and the Z1 voltage stabilizing, protective circuit of voltage regulation is formed in E6 filtering.

The input circuit pulse trigger is by triode, and BG3, BG4 and resistance, electric capacity are formed, and input is P9, P1, P3, P4, P2, P10; Wherein P9, P10 are just triggering effectively for the remote control input receives remote control circuit; P1, P2 trigger effectively for remote control input reception remote control circuit is negative, and P3, P4 are that normal open is born triggering effectively.

The trigger delay circuit is made up of C1, R1, IC1, C2, R2, R3, R4, and IC integrated circuit nor gate IC1A, IC1B, IC1C, IC1D receive trigger impulse, triggers output through C1, R1, C2, R2 time-delay.

Promote circuit and be made up of R5, BG1, R6, BG2, executive circuit is made up of J1, D5, E4, J2, D4, E3, and holding circuit is made up of BHQ.Trigger output and amplify output, carry out, output to motor through BHQ again, make the motor positive and inverse motion, thereby make mechanical door lock realize opening/locking door function through J1J2 through R5, BG1, R6, BG2 switch.

Because the utility model adopts digital timing circuit, has replaced the part discrete component, has improved circuit reliability, has reduced fault rate.
