Abstract

The utility model relates to a controller for electric door locks of automobiles, which is composed of a casing, a motor, a micro switch, a slide block, a transmission gear set, etc. The utility model changes the top-bottom switching structure of traditional casings, and adopts a right-left switching scarf joint structure which switches along the radial directions of a gear shaft and a motor shaft. A shaft bed and other moving elements and associated elements thereof are arranged through integral forming on one side of a casing cover so as to improve the installation rigidity of the gear shaft and the motor shaft and guarantee the assembly precision and the meshing precision of a gear set and a rack of the motor, and simultaneously also enhance the capability of anti-extrusion of the slide block and improve the entire safety performance of door locks of automobiles.

Description

The electric door lock for vehicle controller

The utility model relates to the control setup of electric door lock for vehicle, particularly the improvement of assembly structure.

At present, automobile door lock control setup commonly used mainly is made of elements such as housing, lift component, sliding bar, motor, micro-switch, slide block, driving gear set, briquettings, the assembly of its housing adopts the structure of folding up and down, and promptly assembly direction and motor shaft and gear cluster is axially consistent.Such assembly mode is higher to the formed precision and the assembly accuracy requirement of housing, because the axle bed of mounting teeth wheels and motor shaft lays respectively in the loam cake and lower cover of housing, if axle bed has skew slightly when installing, gear cluster after the installation or motor shaft just can inclination and offsets, make the engagement overbalance between gear, the back lash can not reach designing requirement, is easy to generate the fault that collapses tooth or latch; On the other hand, have relatively high expectations in the gap of slide block and housing, and the slide block of opening-closing structure just in time is in the position of upper and lower covers joint up and down, and the rigidity of housing joint is relatively poor, in case slide block is squeezed, joint is difficult to extenuate the degree of slide block distortion.

The purpose of this utility model is the weak point that overcomes above-mentioned prior art, and a kind of assembly precision of gear cluster and motor shaft, electric door lock for vehicle controller of enhancing element rigidity of improving is provided.

The purpose of this utility model is achieved by the following technical solution: the electric door lock for vehicle controller, include housing, be loaded on the lower housing portion cavity motor 1, be loaded on rear, housing top micro-switch 2, be loaded on the slide block 3 in the place ahead, housing top, the driving gear set 4,5,6 that drives by motor 1 etc., special feature is that housing is divided into left cap 8 and right cap 7, two caps 7,8 are along the radial direction folding assembly of gear wheel shaft 9 and motor shaft 10, and the axle bed 11,12,16 of assembling gear axle 9 and motor shaft 10 takes shape on the cap 8 of single side.

Fig. 1 is a schematic perspective view of the present utility model;

Fig. 2 is the utility model schematic top plan view;

Fig. 3 is the front elevational schematic after the utility model is removed a side cap.

Referring to Fig. 1, Fig. 2 and Fig. 3, principle of work of the present utility model and orthodox car electric door lock control setup are roughly the same, promptly by motor 1 drive gear set 4,5,6, by the tooth bar 13 on the gear 6 drive slide blocks 3, making slide block 3 do front and back in chute 17 slides, thereby drive lift component 14 and press strip 15 motions, realize the unlatching or the locking of automotive door.And the difference of essence is housing is designed to the radially assembly folding along gear wheel shaft 9, motor shaft 10 of left cap 8 and right cap 7, two caps 7,8, and the axle bed 11,12,16 of assembling gear 4,5,6 all takes shape on the left cap 8.Make all moulding or be installed on the cap 8 of single side such as all movable parties such as motor 1, micro-switch 2, slide block 3, driving gear set 4,5,6, press strip 15 and associated components thereof.Such structure advantage is tangible: 1. because axle bed 11,12,16 standards are one-body molded, the assembly precision of gear cluster 4,5,6, motor 1 and slide block 3 is guaranteed, and has guaranteed the quality of gear mesh; 2. axle bed 11,12,16 is shaped on the left cap 8, and rigidity intensity is good, has guaranteed the rigidity of axle mounting; 3. the rigging position of slide block 3 is in the chute 17 of left cap 8 sidewalls, and the gap between slide block 3 and the cap is easy to adjust, and also helps slide block 3 to extenuate the degree that is subjected to gear crimp.4. because the pilot pin of chute 17 and micro-switch takes shape on the cap 8 of a single side left side, make the installation of press strip 15 and micro-switch 2 accurate, guaranteed that micro-switch moves smoothly.

Claims

1, electric door lock for vehicle controller, include housing, be loaded on the lower housing portion cavity motor, be loaded on rear, housing top micro-switch, be loaded on the slide block in the place ahead, housing top, by motor-driven driving gear set etc., it is characterized in that: housing is divided into left and right sides cap, two caps are along the radial direction folding assembly of gear wheel shaft and motor shaft, and the axle bed of assembling gear axle and motor shaft takes shape on the cap of single side.
