Abstract
The utility model discloses an automobile door lock actuator, comprising a housing. The utility model is characterized in that a motor is disposed in the housing; the output end of the motor is connected to a motor gear engaging with a worm gear; the worm of the worm gear is provided with a sliding block, and the center of the worm is provided with a strengthening core rod; the sliding block is connected to a top rod; a positioning sleeve is disposed at the other side of the worm gear corresponding to the worm; a buffer return spring is disposed between the worm gear and the sliding block. The utility model is advantageous in that the noise of the electric actuator is reduced; the impact resistance of a worm gear is strengthened; the structure is simple, volume is small, installation is convenient, generality is good and service life is long.
Description
Technical field
The utility model relates to the car door auxiliary opening device, particularly relates to a kind of automobile door lock actuator.
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, noise short shortcoming in application life big and that cause because of the frequent bump of actuator internal component, the customer automobile overall performance is required the epoch of rising day by day, be easy to cause customer's complaint and complaint.
The utility model content
The purpose of this utility model is to provide a kind of automobile door lock actuator, and it has simple in structure, and volume is little, and it is convenient to install, and carries out the characteristics of the little and long service life of noise.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of automobile door lock actuator, it comprises housing, be provided with motor in the described housing, the output of described motor connects motor gear, and a described motor gear and a gear on worm intermesh, and the worm screw of described gear on worm is provided with slide block, described slide block connects push rod, and be provided with the buffering resetting means between described gear on worm and the slide block, wherein, the center of the worm screw of described gear on worm is provided with the reinforcement plug.
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 automobile door lock actuator is provided with the buffering back-moving spring between gear on worm and slide block, reduced the action noise of whole YE, and is provided with the reinforcement plug in the center of the worm screw of gear on worm, improved the impact strength of scroll bar gear greatly, improved the application life of whole YE, not only simple in structure, volume is little, it is convenient to install, and it is little to carry out noise, and versatility is good, long service life.
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 a kind of automobile door lock actuator of the utility model.
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; 10, strengthen plug.
The specific embodiment
See also shown in Figure 1, Fig. 1 is the sectional drawing of a kind of automobile door lock actuator of the utility model, in present embodiment, a kind of automobile door lock actuator, 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, and the center of described worm screw 6 is provided with strengthens plug 10, the impact strength of gear on worm 4 is improved greatly, thereby improved the application life of whole actuator, 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 this moment, push rod 7 and slide block 5 broke away from, because push rod 7 and slide block 5 are elastic connection ways, made push rod 7 do counter motion by the return elastic force that cushions back-moving spring 9.
Claims (3)
