The gear set includes a first-stage gear, a second-stage double gear, a third-stage double gear, and a transmission shaft gear that mesh sequentially. The motor is installed inside the motor base, and its output shaft is connected to the first-stage gear.

[0005] The transmission shaft gear includes an integrally formed shaft, sector teeth, and rack; the shaft is axially connected between the motor base and the side plate, and both ends are respectively provided with an emergency unlocking rib connected to the emergency unlocking assembly and a locking trigger for triggering the locking confirmation micro switch; the rack meshes with the locking rack, and one side of the locking rack is provided with an unlocking trigger for triggering the unlock confirmation micro switch.

[0006] The emergency unlocking component includes an unlocking slider, a pull rope assembly that pulls the unlocking slider backward, and a reset spring that drives the unlocking slider forward. The unlocking slider is connected to the emergency unlocking rib through a long groove at the bottom.

[0007] The unlocking trigger part is provided with a positioning groove and an arc-shaped unlocking surface located in the positioning groove.

[0008] The transmission shaft gear is provided with an unlocking limit rib in the middle, and the housing is provided with an unlocking limit step that cooperates with the unlocking limit rib.

[0009] Both the motor mount and the side plate have screw holes on their sides.

[0010] The locking rack has slide rails on both sides, and the housing has a first slide groove that is adapted to the slide rails.

[0011] A second groove is formed between the side plate and the housing, and the unlocking slider is disposed in the second groove.

[0012] The motor mount is riveted to the side plate via a riveting post.

[0013] The advantages of this stable new energy vehicle charging dock's European standard electronic lock are as follows: 1. The integrated design of the gear transmission structure results in a small product size, high thrust, and good stability; 2. Dual position signal feedback is added to meet higher requirements; 3. The transmission shaft gear is reinforced with an unlocking limit rib to prevent over-unlocking and emergency unlocking failure; 4. The electronic lock transmission structure does not drive the emergency unlocking component during operation, effectively avoiding the problem of normal locking and unlocking failure caused by the pull rope being stuck in the body.

[0022] Reference Figure 1-7As shown, the European standard electronic lock for a stable new energy vehicle charging dock of this utility model includes a housing 1, a motor 2 housed within the housing 1, a PCB board 3 connected to the motor 2, a retractable locking rod 4 located at the front end of the housing 1, and an emergency unlocking assembly 5 located on one side of the housing 1. A locking rack 6 is provided at the rear end of the locking rod 4. A locking confirmation microswitch 7 and an unlocking confirmation microswitch 8 are provided on the PCB board 3. The motor 2 drives the extension and retraction of the locking rod 4 through a gearbox assembly 9. The gearbox assembly 9 includes a motor mount 10, a side plate 11 located on one side of the motor mount 10, and a gear set 12 located between the motor mount 10 and the side plate 11. The gear set 12 includes a first-stage gear 13, a second-stage double gear 14, a third-stage double gear 15, and a transmission shaft gear 16 that mesh sequentially. The second-stage double gear 14 and the third-stage double gear 15 are both axially connected between the motor mount 10 and the side plate 11 via a gear shaft 36. The motor 2 is installed inside the motor base 10, and its output shaft is connected to the first-stage gear 13. The transmission shaft gear 16 includes an integrally formed shaft portion 17, sector teeth 18, and rack 19. The shaft portion 17 is axially connected between the motor base 10 and the side plate 11, and its two ends are respectively provided with emergency unlocking ribs 20 connected to the emergency unlocking assembly 5 and locking trigger members 21 for triggering the locking confirmation micro switch 7. The rack 19 meshes with the locking rack 6, and one side of the locking rack 6 is provided with an unlocking trigger part 22 for triggering the unlocking confirmation micro switch 8. The sector teeth 18 mesh with the third-stage double gear 15. Thus, by rotating the motor 2 forward and reverse, the locking rod 4 is extended and retracted, thereby achieving locking or unlocking. When locked, the locking trigger member 21 presses against the locking confirmation micro switch 7 to confirm the locking signal; when unlocked, the unlocking trigger part 22 presses against the unlocking confirmation micro switch 8 to confirm the unlocking signal.

[0023] Preferably, the emergency unlocking component 5 includes an unlocking slider 23, a pull rope assembly 24 that pulls the unlocking slider 23 backward, and a return spring 25 that moves the unlocking slider 23 forward. The unlocking slider 23 is connected to the emergency unlocking rib 20 through a long groove 26 at its bottom. With this structure, when in the unlocked state, the emergency unlocking rib 20 is located at the rear end of the long groove 26, ensuring that when the gearbox assembly 9 is locked, the emergency unlocking component does not move synchronously, thus effectively preventing the normal locking / unlocking from failing due to the pull rope being stuck by the machine body.

[0024] Preferably, the unlock trigger 22 is provided with a positioning groove 27 and an arc-shaped unlocking surface 28 located within the positioning groove 27. The button lever of the unlock confirmation micro switch 8 is placed within the positioning groove 27 to ensure stability.

[0025] Preferably, the transmission shaft gear 16 has an unlocking limiting rib 29 in the middle, and the housing 1 has an unlocking limiting step 30 that cooperates with the unlocking limiting rib 29. When unlocked, the unlocking limiting rib 29 is positioned at the end face of the unlocking limiting step 30.

[0026] Preferably, both the motor mount 10 and the side plate 11 are provided with screw holes 31 on their sides. Screws are inserted into the screw holes 31 to fix them into the housing 1 to ensure stability.

[0027] Preferably, the locking rack 6 is provided with slide rails 32 on both sides, and the housing 1 is provided with a first slide groove 33 that adapts to the slide rails 32, so as to ensure the stability of the sliding of the locking rack 6.

[0028] Preferably, a second groove 34 is formed between the side plate 11 and the housing 1, and the unlocking slider 23 is disposed within the second groove 34. This ensures the stability of the sliding of the unlocking slider 23, while also providing a reasonable layout and minimizing space occupation.

[0029] Preferably, the motor mount 10 is riveted to the side plate 11 via a riveting post 35 for easy assembly.
