The DC motor 303 is used as the driving power source. Under the action of the transmission structure composed of the drive helical gear 305 and the worm gear 501, the actuator can have a high output torque. In addition, by integrating the micro switch 302 and the DC motor 303 on the circuit board 301, the micro switch 302 can be triggered by the locking extension movement of the locking tongue 505 to realize the locking signal feedback function.

[0024] In addition, it should be noted that the circuit board 301 is a PCB board. The motor insert, micro switch 302 and cable 304 are soldered onto the PCB board, and then the DC motor 303 is inserted into the motor insert. At this time, the assembly of the circuit board assembly 3 is completed.

[0025] When the circuit board assembly 3 is installed into the lower housing 2, the circuit board assembly 3 is inserted into the lower housing 2, the DC motor 303 is inserted into the U-shaped mounting groove pre-set in the lower housing, and the cable 304 of the circuit board assembly 3 passes through the silicone plug 306 at the tail of the lower housing 2, thus completing the fixed assembly of the circuit board assembly 3.

[0026] In one embodiment, the emergency unlocking component 4 includes a plastic bracket 401 disposed on one side of the circuit board assembly 3.

A wire sleeve 404 is disposed on the outside of the pull cable 403, and one end of the wire sleeve 404 is connected to the side wall of the lower housing 2. A U-shaped groove 4011 that cooperates with the outside of the worm gear 501 is opened at the top of the side of the plastic bracket 401 away from the reaction spring 402, which allows the locking tongue 505 of the actuator to retract by pulling the pull cable 403. The emergency unlocking component 4 does not move with the locking tongue 505 during the locking process, and the pull cable 403 can automatically reset after the emergency unlocking operation is completed.

[0027] In addition, it should be noted that when installing the emergency unlocking component 4, firstly, insert the ball end of the pull cable 403 into the slot at the bottom of the plastic bracket 401, insert the reaction spring 402 into the cylinder of the plastic bracket 401, then pass the pull cable 403 out through the cylindrical hole at the tail of the lower housing 2, and then install the plastic bracket 401 and the reaction spring 402 together in the slot of the lower housing 2.

The other end of the worm gear 501 and located on one side of the driven helical gear 503 is provided with a connecting block 504, and a locking tongue 505 is provided on one side of the connecting block 504. The cross-section of the connecting block 504 is square, and a metal rod 5041 is provided on one side wall of the connecting block 504.

[0029] In addition, it should be noted that when installing the transmission lock tongue assembly 5, firstly, insert the metal rod 5041 into the cylindrical groove on one side of the square structure connecting block 504 of the worm gear 501, then embed the exposed part of the metal rod 5041 into the Z-shaped sliding groove 5051 of the lock tongue 505, and first rotate one cylindrical end of the worm gear 501 into the driven helical gear 503, and then install it into the lower housing 2, thus completing the assembly of the transmission lock tongue assembly 5.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In practical applications, the novel charging socket actuator of this utility model realizes the functions of opening and closing lock, locking signal feedback, and emergency unlocking. When the voltage is applied to drive the DC motor 303, it drives the driven helical gear 503 to rotate clockwise through the helical gear 305. The worm gear 501 pushes the locking tongue 505 to extend vertically along the locking horizontal direction to complete the locking. When the locking tongue 505 extends vertically to the locking position at 90 degrees, the protrusion on the side of the locking tongue 505 will press the micro switch 302, so that the two pins of the micro switch 302 will become a circuit, that is, to realize the feedback locking signal.

[0032] The emergency unlocking function works as follows: pulling the cable 403 causes the plastic bracket 401 to move horizontally along the unlocking position. The U-shaped groove 4011 of the plastic bracket 401 engages with the cylindrical boss 502 at one end of the worm gear 501, causing the worm gear 501 to move horizontally along the unlocking direction, and the locking tongue 505 retracts accordingly. After releasing the cable 403, the plastic bracket 401 and the cable 403 are reset under the action of the reaction spring 402.

[0033] In summary, with the help of the above-mentioned technical solutions of this utility model, the structure of this utility model is simple, reasonable and reliable. It simultaneously achieves the locking function of the actuator, and the locking force is large, preventing accidental dislodgement of the charging gun. The emergency unlocking component 4 enables easy activation of the emergency unlocking function. By setting up the circuit board component 3, using the DC motor 303 as the driving power source, and under the action of the transmission structure composed of the driving helical gear 305 and the worm gear 501, the actuator can have high output torque. Furthermore, by integrating the micro switch 302 and the DC motor 303 onto the circuit board 301, it is possible to... The locking extension movement of the latch 505 triggers the micro switch 302, realizing the locking signal feedback function. By setting the emergency unlocking component 4, the latch 505 of the actuator can be retracted by pulling the cable 403. The emergency unlocking component 4 does not move with the latch 505 during the locking process, and the cable 403 can automatically reset after the emergency unlocking operation is completed. By setting the transmission latch component 5, and under the action of the Z-shaped slide groove 5051 of the latch 505, not only is the locking function of the actuator realized, but the latch 505 also has a huge holding force after locking, thereby preventing the charger from accidentally coming off.
