Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle charging technology, and in particular to an electronic lock for a charging gun motor. Background Technology

[0002] With the continuous development of new energy vehicles (such as electric vehicles and hybrid vehicles that use electricity as power or auxiliary power), the charging demand for new energy vehicles is also constantly increasing. When charging a vehicle using a charging gun, one end of the charging gun is connected to the charging pile, and the other end is mounted on the vehicle. After charging is complete, the charging gun is removed from the vehicle or simultaneously disconnected from both the charging pile and the vehicle. Because the charging gun carries a large current and high voltage during the charging process, plugging and unplugging while the power is on will pose a serious safety hazard. Therefore, how to protect the charging gun located between the vehicle and the charging pile is particularly important, and charging safety issues have gradually attracted people's attention.

[0003] Currently, to prevent safety issues such as hot plugging and unplugging, various electronic locks are added to charging guns on the market. These electronic locks generally include a housing, a motor, a locking pin, a first microswitch, and a second microswitch. During assembly, the second microswitch is assembled separately from the housing, and the second microswitch needs to protrude from the top of the housing. Therefore, a through hole needs to be made separately on the housing for the second microswitch to pass through, and it must be ensured that the size of the microswitch matches the through hole (as shown in the attached diagram). Figure 9 Therefore, the assembly stability between the second micro switch and the housing is poor, and the structure is complex, as shown in Chinese Patent: 2021225912257. At the same time, due to the use of separate assembly, there will be a certain gap between the second micro switch and the housing, which will reduce the overall dustproof and waterproof effect of the electronic lock. If it is exposed to water, dust and other substances for a long time, it will easily cause mechanical failure of the electronic lock and reduce the service life of the electronic lock.

[0030] See also Figures 1 to 8 An electronic lock for a charging gun motor includes a housing 100, a drive motor 200, a locking member 300, a first micro switch 400, and a second micro switch 500 disposed inside the housing 100. The locking member 300 is connected to the output end of the drive motor 200. The first micro switch 400 is located on one side of the drive motor 200 and cooperates with the locking member 300. The second micro switch 500 is disposed at the end away from the locking member 300, and the housing 510 of the second micro switch 500 is integrally designed with the housing 100. The top of the housing 510 of the second micro switch 500 protrudes from the housing 100. Both the first micro switch 400 and the second micro switch 500 are waterproof micro switches, and sealing caps 600 are respectively provided at the push points of the first micro switch 400 and the second micro switch 500.

[0031] Specifically, in this embodiment, both the first micro switch 400 and the second micro switch 500 are waterproof micro switches, which can improve the overall dustproof and waterproof performance of the electronic lock. The first micro switch 400 and the second micro switch 500 have the same structure, both including a housing, a base, a terminal assembly, and a button. The housing 510 of the second micro switch 500 is integrally designed with the housing 100. Therefore, there is no need to drill holes in the housing 100, allowing the second micro switch 500 to be directly assembled with the housing 100. This improves the assembly stability between the second micro switch 500 and the housing 100 and simplifies the overall structure of the electronic lock. Furthermore, due to the integral molding design, there are no gaps between the second micro switch 500 and the housing 100, effectively improving the dustproof effect on the housing 100, thereby reducing the probability of mechanical failure and extending the service life of the electronic lock.

[0032] Meanwhile, to ensure the waterproof performance of the first micro switch 400 and the second micro switch 500, sealing caps 600 are respectively provided at the buttons of the first micro switch 400 and the second micro switch 500. The bottom of the sealing cap 600 is provided with a fixing part 610. The fixing part 610 can bond or heat-melt the bottom of the sealing cap 600 to the rubber shell of the micro switch. A limiting part 620 is provided on the inner wall of the sealing cap 600. The limiting part 620 is inserted into the groove on the peripheral wall of the button, so that the sealing cap 600 can cover the button. By covering the button with the sealing cap 600, the waterproof performance of the first micro switch 400 and the second micro switch 500 is improved.

[0033] In addition, to facilitate the assembly of the electronic lock, the housing 100 in this embodiment includes a bottom shell 110 and a top cover 120. The housing 510 of the second micro switch 500 and the top cover 120 are integrally molded. The top cover 120 is connected to the bottom shell 110. The connection between the top cover 120 and the bottom shell 110 can be achieved by heat fusion, laser welding, or ultrasonic welding. By connecting the top cover 120 and the bottom shell 110 in the above manner, the connection stability between the top cover 120 and the bottom shell 110 can be improved compared with the snap-fit ​​connection in the prior art, thereby making the overall assembly of the electronic lock more robust.

[0034] Furthermore, in this embodiment, the drive motor 200, locking member 300, first micro switch 400, and second micro switch 500 are respectively disposed within the housing 100. The locking member 300 is connected to the output terminal of the drive motor 200 and cooperates with the first micro switch 400 after connection. When the electronic lock is working, it supplies power to the drive motor 200, which in turn drives the locking member 300 to rotate, thereby achieving locking and unlocking. During the rotation, the locking member 300 acts on the first micro switch 400, causing the first micro switch to... The 400 feedback signal provides feedback on the locking and unlocking status of the electronic lock, thereby ensuring the security of the electronic lock. The second micro switch 500 provides feedback on the charging gun button signal. In order for the locking member 300 to realize the locking function and cooperate with the first micro switch 400, the locking member 300 includes a locking part 310 and a triggering part 320. When the drive motor 200 drives the locking member 300 to rotate, the locking part 310 can realize locking / unlocking, and at the same time, the triggering part 320 acts on the first micro switch 400 to realize signal feedback.

[0035] Please see Figure 4 and Figure 5 To waterproof the drive motor 200, a sealing box 700 is wrapped around the drive motor 200. The conveying end of the drive motor 200 extends from one end of the sealing box 700 and connects to the locking member 300. A sealing ring 730 is fitted at the extension. A cover 710 is sealed at the other end of the sealing box 700. The sealing box 700, the sealing ring 730, and the cover 710 achieve a complete seal for the drive motor 200, thereby ensuring the waterproof performance of the drive motor 200 and improving the waterproof effect of the electronic lock.

[0036] Finally, please see Figure 3 and Figure 4 In order to assemble the electronic lock, a positioning post 720 is provided at the bottom of the sealing box 700, and a positioning hole 130 corresponding to the positioning post 720 is provided at the bottom of the housing 100. After the drive motor 200 is sealed and installed in the sealing box 700, the sealing box 700 is then installed into the housing 100, and the positioning post 720 at the bottom of the sealing box 700 is inserted into the positioning hole 130 at the bottom of the housing 100. This achieves the positioning of the sealing box 700 and ensures the assembly stability between the drive motor 200, the locking component 300 and the housing 100.

[0037] Meanwhile, in this embodiment, a limiting protrusion 740 is provided on one side of the sealing box 700. When the sealing box 700 is assembled into the housing 100, the limiting protrusion 740 on the side wall of the sealing box 700 will form a limiting groove 800 with the inner wall of the housing 100. The first micro switch 400 is installed in the limiting groove 800, thereby ensuring that the first micro switch 400 can cooperate with the locking member 300 to realize signal feedback.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
