Description

Technical Field

[0001] The utility model relates to the technical field of electric actuators, in particular to a novel electric actuator. Background Art

[0002] The broadest definition of an actuator is: a drive device that can provide linear or rotary motion, which uses some kind of drive energy and works under some kind of control signal; the actuator uses liquid, gas, electricity or other energy and converts it into a drive action through a motor, cylinder or other device.

[0003] The invention proposed by the Chinese patent announcement number CN109723878A provides a new type of electric actuator, including a power supply, a motor, a control system, a drive system and an intelligent protection system. The intelligent protection system includes an information collection unit, a protection control unit, a position sensing unit and an alarm unit. The alarm unit includes a buzzer alarm and a wireless remote alarm module. When the environment is dangerous, the sensor in the information collection unit collects information and transmits it to the protection control unit. Once the protection control unit finds a risk, it sends an instruction to the position sensing unit. The position sensing unit controls the entire actuator to move to a safe position, and then sends information to the alarm unit. The buzzer alarm alerts the on-site staff, and the wireless remote alarm module alerts the command center. The present invention can quickly move the electric actuator to a safe position in dangerous situations, saving the time of background feedback and effectively protecting the electric actuator.

[0004] When implementing the above scheme, the applicant found that the existing electric actuators are usually installed on outdoor pipes. When the electric actuators are exposed to the sun for a long time, they will generate high temperatures, thereby reducing the service life of the electric actuators and affecting the normal use of the device. Based on this, the present utility model designs a new electric actuator to solve the above problems. Utility Model Content

Therefore, starting the servo motor 5 can drive the sun visors 8 to move closer to or farther away from each other.
