Problems solved by technology

At present, the door lock electric actuators on the market are divided into two types: rotary type and push-pull type. The rotary type can only perform locking and unlocking functions, and the push-pull type can perform electric unlocking functions. There is no actuator that can perform rotation and linear motion. two functions

Abstract

The invention discloses an electrodynamic actuator, which comprises a housing, wherein an electric machine is disposed in a chamber of the housing; an output shaft of the electric machine is connected with a worm; the worm is engaged with a worm wheel at the upper end of the worm; a mid gear is fixedly connected to the worm wheel shaft of the worm wheel; the mid gear is engaged with a transmitting gear at the right end of the mid gear; the transmission gear is connected with a power take-off by a transmission shaft; and the power take-off is a cam. By using the cam as the power take-off, the electrodynamic actuator can make rotational movement, and the rotational movement of the actuator can be converted into lineal movement, thereby achieving the two rotational and linear functions of the actuator. In addition, by adopting the cam as a power transmission device, the transmission can be smooth, without impact, and has small noise.

Description

technical field [0001] The invention relates to an electric actuator. Background technique [0002] Electric actuator, also known as electric actuator; it is a driving device that can provide linear or rotary motion, which uses a certain driving energy and works under the action of a certain control signal. The advantages of electric actuators are convenient energy access, fast signal transmission speed, long transmission distance, convenient centralized control, high sensitivity and precision, convenient cooperation with electric regulating instruments, and simple installation and wiring. At present, the door lock electric actuators on the market are divided into two types: rotary type and push-pull type. The rotary type can only perform locking and unlocking functions, and the push-pull type can perform electric unlocking functions. There is no actuator that can perform rotation and linear motion. Two functions. Contents of the invention [0003] The object of the pres...
