Abstract
The utility model discloses an electric actuator for an automobile door lock, which comprises a shell. A motor is arranged in the shell. An output end of the motor is connected with a motor gear. The motor gear is meshed with a worm gear. A worm of the worm gear is provided with a sliding block. The sliding block is connected with an ejector rod. The other side of the worm gear relative to the worm is provided with a positioning sleeve. A buffer reset spring is arranged between the worm gear and the sliding block. The buffer reset spring is arranged between the worm gear and the sliding block, and thus, the sliding block decelerates under the action of the spring after completing the function so as to greatly reduce the action noise of the whole electric actuator. The electric actuator for the automobile door lock has the advantages of simple structure, small volume, convenient and rapid installation, low actuation noise and good universality.
Description
Technical field
The utility model relates to the car door auxiliary opening device, particularly relates to a kind of electric actuator for gate lock of automobile.
Background technology
At present, along with expanding economy, automobile becomes people's instrument used in everyday, the customer is by the demand of originally demand of automobile function being brought up to gradually performance, need manually to come the inconvenient people of opening automobile door lock to design various autonomous driving vehicle door lock opening devices before being directed to, opening executer is an important assembly in autonomous driving vehicle door lock opening device, but there is complex structure in traditional opening executer, volume is big, install loaded down with trivial details, the shortcoming that noise is bigger requires the epoch of rising day by day the customer to the automobile overall performance, is easy to cause customer's complaint and complaint.
The utility model content
The purpose of this utility model is to provide a kind of electric actuator for gate lock of automobile, and it has simple in structure, and volume is little, installs convenient and the little characteristics of execution noise.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of electric actuator for gate lock of automobile, it comprises housing, be provided with motor, transmission component and push rod in the described housing, the output of described motor connects motor gear, wherein, described transmission component comprises and the intermeshing gear on worm of motor gear that the worm screw of described gear on worm is provided with slide block, described slide block connects push rod, and is provided with the buffering resetting means between described gear on worm and the slide block.
Described buffering resetting means is a spring.
Described gear on worm is provided with positioning sleeve with respect to the opposite side of worm screw.
The beneficial effects of the utility model are, described electric actuator for gate lock of automobile is provided with the buffering back-moving spring between gear on worm and slide block, slide block is slowed down under the effect of spring after finishing function, greatly reduce the action noise of whole YE, not only simple in structure, volume is little, and it is convenient to install, and it is little to carry out noise, and versatility is good.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the sectional drawing of the utility model electric actuator for gate lock of automobile.
Among the figure:
1, housing; 2, motor; 3, motor gear; 4, gear on worm; 5, slide block; 6, worm screw; 7, push rod; 8, positioning sleeve; 9, buffering back-moving spring.
The specific embodiment
See also shown in Figure 1, Fig. 1 is the sectional drawing of the utility model electric actuator for gate lock of automobile, in present embodiment, a kind of electric actuator for gate lock of automobile, described electric actuator for gate lock of automobile comprises housing 1, be provided with motor 2 in the described housing, the output of described motor 2 connects motor gear 3, described motor gear 3 intermeshes with the gear on worm 4 that is arranged at motor 2 one sides, the worm screw 6 of described gear on worm 4 is provided with slide block 5, described slide block 5 connects push rod 7, so that slide block 5 drives push rod 7 motions under the effect of gear on worm 4, described gear on worm 4 is provided with positioning sleeve 8 with respect to the opposite side of worm screw 6, and be provided with buffering back-moving spring 9 between described gear on worm 4 and the slide block 5, described buffering back-moving spring 9 slows down slide block 5 under its effect after finishing function, greatly reduce the action noise of whole YE.
During work, the external control electric current enters motor 2 by connector, and motor 2 rotatablely moves under the effect of electric current and drives motor gear 3, and motor gear 3 drives scroll bar gear 4, and scroll bar gear 4 drives slide block 5 motions, and slide block 5 drives push rod 7 motions.When slide block 5 moved to certain position, buffering back-moving spring 9 was up to the final position, and at this moment because push rod 7 and slide block 5 are elastic connection ways, push rod 7 and slide block 5 break away from does counter motion.
