Abstract

The invention provides a micro actuator for an oil filler cap and a charging cap. The micro actuator comprises a lock bracket assembly and a lock rod. The lock bracket assembly comprises a base, a locking plate and a motor. A motor cavity and a locking cavity are formed in the base. The motor cavity is sealed. One end of the locking cavity is opened. The locking plate and a resetting piece are mounted in the locking cavity. A lock hole and lock lugs are arranged at the center of the locking plate. The motor, a gear, a gear sleeve and a positioning pin are mounted in the motor cavity. A slide block at one end of the positioning pin is arranged in an arc-shaped groove in the end surface of the gear sleeve. The other end of the positioning pin extends into the locking cavity. The resetting piece is locked at the other end of the positioning pin. A first slope, a second slope, a first guiding groove, a second guiding groove, a yielding groove and a locking groove are formed in the outer wall of the lock rod. When the lock rod is inserted in the lock hole, the lock lugs enter a part between the first slope and the second slope along the second guiding groove and are locked in the locking groove under the resetting action of the resetting piece. The motor drive way and the pressing drive way are integrated, the micro actuator is simple and compact in structure, and small in size, the design space is saved, operation is convenient, and locking is reliable.

Description

technical field [0001] The invention relates to a micro-actuator for a small door for refueling and a small door for charging. Background technique [0002] The refueling wicket at the refueling port of the automobile or the charging wicket at the charging port of the electric vehicle all have the effect of respectively protecting the refueling port or the charging port and beautifying. In order to prevent the refueling small door or the charging small door from being opened, a locking device is arranged between the fueling small door or the charging small door and the vehicle body for fixing. The current locking device not only has an extremely complicated structure and takes up a lot of space, but also has the disadvantages of not being tightly closed, and is easy to open under the action of an external force, which is extremely inconvenient to use. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings in the prior art, the present inv...
