In this embodiment, the unlocking gear 61 includes a gear portion 611 and a toothless portion 612. When the second end of the pull rope 62 moves away from the housing 1, the pull rope 62 drives the unlocking gear 61 to rotate. The unlocking gear 61 engages with the gear assembly 2 for transmission. The gear assembly 2 is connected to the screw assembly 4 for transmission. The screw assembly 4 drives the locking rod assembly 5 to unlock.

[0035] Please see Figure 5 The second drive assembly 6 also includes a pull cord storage component 63. The pull cord storage component 63 is disposed inside the housing 1 and on the unlocking gear 61, and the first end of the pull cord 62 is connected to the pull cord storage component 63. Specifically, the pull cord storage component 63 is fixedly connected to the unlocking gear 61, and the first end of the pull cord 62 is fixedly connected to the pull cord storage component 63.

[0036] Please see Figure 5The pull cord storage component 63 is provided with a receiving groove 631. The first end of the pull cord 62 is provided with a fixing part 621. The fixing part 621 is embedded in the receiving groove 631, thereby realizing the fixed connection between the first end of the pull cord 62 and the pull cord storage component 63.

[0037] Please see Figures 1-3 and Figure 5 The second drive assembly 6 also includes: a sheath 64, a first buckle 65, a second buckle 66, a protective element 67, and a pull ring 68.

[0038] The sheath 64 is disposed outside the housing 1 and fitted onto the pull rope 62, thereby protecting the pull rope 62.

[0040] Please see Figure 1 The charging dock opener also includes a seal 9. The seal 9 is fitted onto the locking rod 51 to ensure the seal between the locking rod 51 and the housing 1.

[0041] Please see Figure 1 The charging dock opening and closing device also includes a cover plate 10. The cover plate 10 is disposed on the housing 1 and is used to protect the structure inside the housing 1.

[0042] Please see Figure 3In this application, the motor 31 of the first drive assembly 3 drives the worm 32 to rotate. The worm 32 meshes with the worm wheel 21 of the gear assembly 2. The worm 32 drives the worm wheel 21 to rotate, which in turn drives the first gear 22 to rotate. The first gear 22 meshes with the screw gear 42 of the screw assembly 4, which in turn drives the screw gear 42 to rotate. The screw gear 42 then drives the screw 41 to rotate, causing the connecting piece 52 to slide on the thread 412 of the screw 41. The connecting piece 52 then drives the locking rod 51 to descend and lock, thus achieving locking of the locking rod assembly 5 using the first drive assembly 3. It is worth noting that during the locking process of the locking rod assembly 5 using the first drive assembly 3, neither the gear part 611 nor the toothless part 612 is connected to the gear assembly 2. In other words, the unlocking gear 61 does not rotate with the gear assembly 2. The charging dock opener of this application has a large self-locking force, making it difficult to pull out the charging gun and increasing safety.

[0043] Please see Figure 3 In this application, the motor 31 of the first drive assembly 3 drives the worm 32 to rotate. The worm 32 meshes with the worm wheel 21 of the gear assembly 2. The worm 32 drives the worm wheel 21 to rotate, which in turn drives the first gear 22 to rotate. The first gear 22 meshes with the screw gear 42 of the screw assembly 4, which in turn drives the screw gear 42 to rotate. The screw gear 42 then drives the screw 41 to rotate, causing the connecting piece 52 to slide on the thread 412 of the screw 41. The connecting piece 52 then drives the locking rod 51 to rise and unlock, thus achieving the unlocking of the locking rod assembly 5 by driving the locking rod assembly 5 with the first drive assembly 3. It is worth noting that during the unlocking process of the locking rod assembly 5 by driving the locking rod assembly 5 with the first drive assembly 3, neither the gear part 611 nor the toothless part 612 is connected to the gear assembly 2. In other words, the unlocking gear 61 does not rotate with the gear assembly 2.

[0044] Please see Figure 3 When the second end of the pull cord 62 is pulled away from the housing 1, the pull cord 62 drives the unlocking gear 61 to rotate. The unlocking gear 61 meshes with the second gear 23 of the gear assembly 2. The second gear 23 drives the first gear 22 to rotate. The first gear 22 meshes with the screw gear 42 of the screw assembly 4. The first gear 22 drives the screw gear 42 to rotate. The screw gear 42 drives the screw 41 to rotate, causing the connecting piece 52 to slide on the thread 412 of the screw 41. The connecting piece 52 drives the locking rod 51 to rise and unlock, thus realizing the unlocking of the locking rod assembly 5 by driving the second drive assembly 6. It is worth noting that the unlocking gear 61 meshes with the second gear 23 of the gear assembly 2, specifically in the form of a transmission connection between the gear part 611 and the second gear 23 of the gear assembly 2. Therefore, in emergency situations such as power failure, the second drive assembly 6 can be used to drive the locking rod assembly 5 to unlock, avoiding the phenomenon that the charging gun cannot be pulled out due to the inability to unlock due to power failure, which could lead to product damage.

[0045] Please seeFigure 3 When the pull rope drives the unlocking gear to rotate, thereby unlocking the locking rod assembly, the motor 31 of the first drive assembly 3 drives the worm 32 to rotate. The worm 32 meshes with the worm wheel 21 of the gear assembly 2. The worm 32 drives the worm wheel 21 to rotate, which in turn drives the first gear 22 to rotate. The first gear 22 meshes with the screw gear 42 of the screw assembly 4. The first gear 22 drives the screw gear 42 to rotate, which in turn drives the screw 41 to rotate. This causes the connecting piece 52 to slide on the thread 412 of the screw 41. The connecting piece 52 then drives the locking rod 51 to descend and lock, thus achieving the locking of the locking rod assembly 5 using the first drive assembly 3. It is worth noting that during the process of re-locking the locking rod assembly 5 using the first drive assembly 3, the gear assembly 2 engages with the unlocking gear 61. The unlocking gear 61 rotates, causing the second end of the pull rope 62 to move towards the housing 1. Specifically, the gear assembly 2 engages with the gear portion 611 of the unlocking gear 61.

[0046] The second drive assembly 6 of the charging dock opener of this application uses a pull rope 62 to drive the unlocking gear 61 to rotate. The unlocking gear 61 meshes with the gear assembly 2 for transmission. The gear assembly 2 is connected to the screw assembly 4 for transmission. The screw assembly 4 drives the locking rod assembly 5 to unlock. The traditional unlocking handle is eliminated, and the unlocking gear 61 is set inside the housing 1. The structure is more compact, which can reduce the space occupied and improve the installation adaptability of the charging dock opener.

[0047] The charging dock opener provided in this application has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this application. The description of the above embodiments is only for the purpose of helping to understand the core idea of ​​this application. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this application. Therefore, the content of this specification should not be construed as a limitation of this application.
