Description

Technical Field

[0001] The utility model relates to an electric actuator, in particular to an electric actuator with a guide support structure. Background Art

[0002] Patent document CN220488151U discloses a locking assembly of an electric actuator, including an actuator body and a locking mechanism, wherein the locking mechanism is installed inside the actuator body, and the locking mechanism includes a screw, a motor, a worm, a worm wheel, a gear, an electric push rod, a chuck and a tooth groove. A screw connected to the control end of the actuator assembly is installed vertically inside the actuator body, and a gear is installed on the surface of the screw. Under normal use, the chuck at the power end of the electric push rod is away from the gear on the outer periphery of the screw. When the screw operates normally and reaches a certain position that needs to be locked, the operation of the electric push rod can be controlled so that the chuck fits against the gear surface and meshes with the gear. The chuck can further lock the screw to keep its position stable. The gear is long, so that the screw can be locked by the chuck under different operating conditions.

[0003] However, the force output by the electric actuator is a rotational output force. When a linear output force is required, it is difficult for the electric actuator to adapt to a device that converts the rotational force into a linear thrust, which is very inconvenient. Therefore, it is necessary to improve such a structure to overcome the above defects. Utility Model Content
