By referring to these contents, ordinary technicians in this field should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] According to an embodiment of the present utility model, a charging gun electronic lock is provided.

[0025] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-Figure 5 As shown, the electronic lock of the charging gun according to the embodiment of the present invention includes a lower shell 1, an upper shell 2 is provided on the top of the lower shell 1, a lock pin 3, a motor shell 4 and a plug 5 are sequentially provided inside the lower shell 1, and a micro switch 6 is provided on one side of the motor shell 4; multiple sliding lock mechanisms 7 are provided on both sides of the lower shell 1, a manual keyhole 8 is provided at one end of the lower shell 1, and a pin connector 9 is provided at the other end of the lower shell 1, and the pin connector 9 is connected to the S switch 10 through a cable.

[0026] With the help of the above technical solution, the electronic lock, through the design of an electronic pin-type connection structure, can be quickly installed and connected to the charging gun. A sealing structure is designed to prevent water and dust from entering the charging gun plug. At the same time, the S switch 10, a consumable part of the charging gun, is integrated into the pin-type connector 9 of the electronic lock. This allows for quick replacement and repair of the charging gun even if the S switch 10 is damaged. This has the advantages of simple and sophisticated design and low production process requirements. The electronic lock is compact and can effectively reduce subsequent operating and maintenance costs. By using a reduction DC motor as the driving element to drive the rotation of the lock pin 3, the electronic lock can achieve locking, mechanical unlocking, and signal feedback functions. At the same time, the pin-type connector structure design and the use of electronic pins can achieve plug-in connection between the electronic lock and the charging gun circuit, thereby realizing rapid replacement of the electronic lock. In addition, the sliding lock mechanism 7 can effectively ensure the connection strength between the upper and lower shells, and can be quickly disassembled and replaced during replacement, reducing maintenance difficulty.

[0027] In one embodiment, for the above-mentioned lower shell 1, a placement rack 11 that cooperates with the motor shell 4 is provided at the bottom of the lower shell 1, a switch rack 12 that cooperates with the micro switch 6 is provided on one side of the bottom of the lower shell 1, and a plurality of side strips 13 are provided on the side of the lower shell 1 away from the locking pin 3, and a buffer strip 14 is provided at the top of the motor shell 4, so that the motor shell 4 inside the lower shell 1 can be firmly clamped and fixed to prevent the reduction motor 15 inside the motor shell 4 from shaking or offsetting during operation.

[0028] In one embodiment, for the above-mentioned motor housing 4, a reduction motor 15 is provided inside the motor housing 4, and a driving sealing ring 16 is provided on the side of the motor housing 4 close to the lock pin 3. The output end of the reduction motor 15 is connected and matched with the lock pin 3, and the reduction motor 15 and the micro switch 6 are both connected to the pin connector 9 through a cable, thereby realizing the communication connection of the internal electronic devices, and reading and transmitting the signals of the reduction motor 15 and the micro switch 6 through the pin connector 9 to realize the automatic locking and signal feedback of the electronic lock.

[0029] In one embodiment, for the upper shell 2 described above, a lock pin hole 17 cooperating with the lock pin 3 is provided on the top of the upper shell 2 , and mounting ears 18 are provided on both sides of the upper shell 2 , so that the lock pin 3 can work normally.

[0030] In one embodiment, for the above-mentioned sliding lock mechanism 7, the sliding lock mechanism 7 includes two arched slide rails 701 arranged on one side of the lower shell body 1, an embedded slider 702 is arranged between the upper and lower arched slide rails 701, an elastic buckle plate 703 is arranged on the top of the embedded slider 702, and a buckle tooth 704 is arranged on the inner side of the top of the elastic buckle plate 703, and a buckle groove 705 that cooperates with the buckle tooth 704 is opened on one side of the upper shell body 2. The vertical section of the buckle tooth 704 is a right-angled trapezoidal structure, and the cross-section of the buckle groove 705 is a right-angled trapezoidal structure, and the length of the buckle groove 705 is smaller than the length of the arched slide rail 701, so that the embedded slider 702 can slide in the horizontal direction to drive the elastic buckle plate 703 and the buckle tooth 704 to move in translation, and the buckle tooth 704 and the buckle groove 705 are engaged with each other to achieve a fixed connection between the upper shell body 2 and the lower shell body 1, thereby improving the stability of the electronic lock.

[0031] The operating principle of the sliding lock mechanism 7 is that in the fixed state, the locking tooth 704 is located within the sliding groove 705, and the embedded slider 702 is located on one side of the arched slide rail 701. The embedded slider 702 is a convex structure that can be restrained up and down within the arched slide rail 701. Its surface is equipped with anti-slip protrusions that the operator can press and slide. During the unlocking process, by sliding the embedded slider 702 to the other side, the locking tooth 704 gradually slides within the sliding groove 705. Since the sliding groove 705 is a trapezoidal structure with one side inclined until it is flush with the side surface of the upper shell 2, the locking tooth 704 is now free from the sliding groove 705, and the upper shell 2 is no longer restrained, and can be dragged upward to be removed. In addition, the upper surface of the latch 704 is a slope, and the elastic latch plate 703 provides an elastic force inward. When the upper shell 2 is installed downward, the elastic latch plate 703 can be gradually pushed outward by contacting the upper slope of the latch 704 until it contacts the lower shell 1, and then the embedded slider 702 is driven to fasten and lock it.

[0032] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0033] In actual application, the lock pin 3 and the micro switch 6 together form a locking and signal feedback component, which is assembled as follows: a D-shaped hole is designed on the mounting surface of the lock pin 3 to embed the output shaft of the reduction motor 15, thereby assembling the lock pin 3 and the output shaft of the reduction motor 15 into one. Then assemble it together with the micro switch 6 into the lower shell 1, and the cables of the reduction motor 15 and the micro switch 6 are led out from the tail of the lower shell 1, and then the upper shell 2 is fastened together by ultrasonic welding, thereby completing the locking and signal feedback component. The reduction motor 15 is connected to a positive direction DC power, and the motor output shaft will drive the lock pin 3 to rotate clockwise and counterclockwise. The lock pin 3 has a stop structure in the lower shell 1, which will limit the rotation angle of the lock pin 3 to 45°. When the lock pin 3 rotates counterclockwise by 45°, the electronic lock is locked, and the lock pin 3 will trigger the micro switch 6 to close and complete the signal feedback output; otherwise, it is an unlocking operation. At the same time, a manual lock hole 8 is provided at one end of the lower shell 1, and a tool can be inserted into the interior to rotate the lock pin 3 to complete manual unlocking.

[0034] The electronic lock cable and the S-switch 10 cable are then soldered to the electronic plug-in. This plug-in is then inserted into the pin connector 9 and potted with epoxy resin to seal the solder joints. This completes the pin connector assembly. This pin connector assembly can be plugged into the charging gun circuitry, allowing for quick replacement if the electronic lock becomes damaged, saving maintenance time.

[0035] In summary, with the help of the above-mentioned technical solutions of the present invention, the electronic lock with an electronic pin-type connection structure can be quickly installed and connected to the charging gun. A sealing structure is designed to prevent water and dust from entering the charging gun plug. At the same time, the S switch 10, a consumable part of the charging gun, is integrated into the pin-type connector 9 of the electronic lock, so that even if the S switch 10 is damaged, the charging gun can be quickly replaced and repaired. This has the advantages of simple and sophisticated design and low production process requirements. The electronic lock is compact and can effectively reduce subsequent operating and maintenance costs. By using a reduction DC motor as the driving element to drive the lock pin 3 to rotate, the electronic lock can achieve locking, mechanical unlocking and signal feedback functions. At the same time, through the pin-type connector structure design and the use of electronic pins, the electronic lock and charging gun circuit can be plugged together, thereby realizing rapid replacement of the electronic lock. In addition, in conjunction with the sliding lock mechanism 7, the connection strength between the upper and lower shells can be effectively guaranteed, and replacement can be quickly disassembled and replaced during replacement, reducing maintenance difficulty.
