Abstract
The utility model discloses an electric actuator of an automobile door lock. The electric actuator comprises a box body and a motor, a worm, a first transmission gear and a second transmission gear mounted in the box body; a power output shaft of the motor is connected with the worm; the worm is meshed with the first transmission gear; the first transmission gear is meshed with the second transmission gear; the box body is also provided with a wiring end; a wire is led out from the inside of the wiring end; one end of the wire is electrically connected with an external power supply; and the other end of the wire is electrically connected with the motor. An internal circuit of the electric actuator of the automobile door lock is connected by the wire; compared with the prior art, the electric actuator has the advantages that the wires can be arranged at will without spatial restriction, and short circuit caused by possible poor plastic coating effect and incomplete punching in the production procedures and production process can be reduced, thereby improving the quality stability of the product.
Description
Technical field
The utility model relates to a kind of automobile door lock assembly, especially relates to a kind of electric actuator for gate lock of automobile.
Background technology
At present, existing electric actuator for gate lock of automobile is connected with the actuator interface by external power source when work; The actuator internal transmission needs first punching press copper sheet to adopting copper sheet to connect between motor or the microswitch when producing, carry out plastic then; The contact between each copper sheet is cut off in punching press again after plastic, because the gap is little between the copper sheet; And sheet material is thinner, so very easily distortion in the manufacturing process, can produce in the plastic process that plastic bag puts in place or copper sheet and copper sheet between form short circuit; And be prone to produce the phenomenon of not cutting off during final cutting, form short circuit, cause the YE fault.
Obviously, the external power source of existing electric actuator for gate lock of automobile is connected with the actuator interface, and the actuator internal transmission exists installation procedure loaded down with trivial details, poor stability, the shortcoming of security reliability difference to the connected mode between motor or the microswitch.
The utility model content
To the problems referred to above, the purpose of the utility model is to provide a kind of electric actuator for gate lock of automobile, its have simple in structure, be easy to process and characteristics that security reliability is good, to solve the problem of existing electric actuator for gate lock of automobile.
The purpose of the utility model is to realize through following technical scheme:
A kind of electric actuator for gate lock of automobile, it comprises box body and is installed on the motor in the box body, worm screw; First, second travelling gear, wherein, the power output shaft of said motor connects worm screw; Said worm screw and the engagement of first travelling gear, said first travelling gear and the engagement of second travelling gear, and also be provided with terminals on the said box body; Draw lead in the said terminals, an end of said lead electrically connects external power source, and the other end electrically connects motor.
Especially, on said second travelling gear power transmission shaft is installed, on the said power transmission shaft cam is installed.
The beneficial effect of the utility model does; The internal circuit of said electric actuator for gate lock of automobile adopts lead to connect; Compared with prior art can discretionary wiring (method), do not receive the constraint in space, reduced simultaneously possibly occur in production process and the manufacturing process plastic bad and die-cut imperfect; Cause the phenomenon of short circuit, improve product quality stability.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the utility model electric actuator for gate lock of automobile.
Among the figure:
1, box body; 2, motor; 3, worm screw; 4, first travelling gear; 5, second travelling gear; 6, power transmission shaft; 7, cam; 8, terminals; 9, lead.
The specific embodiment
Please with reference to shown in Figure 1, Fig. 1 is the structural representation of the utility model electric actuator for gate lock of automobile.In the present embodiment, a kind of electric actuator for gate lock of automobile comprises box body 1 and is installed on the motor 2 in the box body 1, worm screw 3; First travelling gear 4 and second travelling gear 5; The power output shaft of said motor 2 connects worm screw 3, said worm screw 3 and 4 engagements of first travelling gear, said first travelling gear 4 and 5 engagements of second travelling gear; And also be provided with terminals 8 on the said box body 1; Draw lead 9 in the said terminals 8, an end of said lead 9 electrically connects external power source, and the other end electrically connects motor 2.
During work; The external control electric current gets into motor 2 through lead 9; Motor 2 rotatablely moves under the effect of electric current and drives motor worm 3, and worm screw 3 drives first travelling gear, 4, the first travelling gears 4 and drives 5 motions of second travelling gear; Second travelling gear 5 drives cam 7 motions through power transmission shaft 6, promotes the operate outside part by cam 7 and carries out work.
The internal circuit of above-mentioned electric actuator for gate lock of automobile adopts lead 9 to connect; Can discretionary wiring (method), do not receive the constraint in space, reduced simultaneously possibly occur in production process and the manufacturing process plastic bad and die-cut imperfect; Cause the phenomenon of short circuit, improve product quality stability.
