Specific implementation mode

[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present utility model.

[0024] The specific embodiments of the present utility model will be described below with reference to the drawings. Specific embodiment one:

[0026] Refer to Figures 1-7, A lead-acid charging port with a safety performance-enhanced structure including a gun body 1 and a charging female head 3. The end of the gun body 1 is provided with a charging male head 2. The lead-acid charging port is the charging port of the charging gun, that is, the charging port on the charging male head 2. The charging male head 2 is docked with the charging female head 3 to achieve power transmission. Sliding grooves 4 are opened on the surfaces of both the gun body 1 and the charging male head 2. The sliding grooves 4 provide a track for the movement of the slider 7. The surface of the sliding groove 4 is provided with a slider 7. The movement of the safety cover 8 is controlled by sliding the slider 7. The shape of the slider 7 is T-shaped and is adapted to the sliding groove 4. Fixed grooves 14 are opened on both sides of the slider 7. The safety cover 8 is hinged to the surface of the slider 7. The safety cover 8 plays a role in dust prevention, waterproofing and safety protection. An electromagnet 10 is provided on the surface of the safety cover 8. An iron block 11 is embedded in the surface of the charging male head 2. The electromagnet 10 realizes energization and de-energization through communication with the control main board 9. When de-energized, the iron block 11 is released, allowing the safety cover 8 to be opened. When energized, the iron block 11 is adsorbed, firmly fixing the safety cover 8. An NFC reading area 15 is provided on the surface of the safety cover 8. Through the setting of the NFC reading area 15, NFC technology is supported. By reading NFC tags or device information, rapid authentication is realized to ensure that only authorized users can open the safety cover 8. A fingerprint recognition area 16 is provided on the surface of the safety cover 8. Through the setting of the fingerprint recognition area 16, it is convenient to identify the fingerprint information of the user and verify the user's identity to ensure that only authorized users can open the safety cover 8. A control main board 9 is provided inside the charging male head 2. The fingerprint recognition area 16 and the NFC reading area 15 are respectively electrically connected to the control main board 9. The control main board 9 is responsible for receiving the identity verification information from the NFC reading area 15 and the fingerprint recognition area 16 and controlling the energization and de-energization of the electromagnet 10 according to the verification result.

[0027] Moving grooves 12 are opened on both sides of the sliding groove 4. A fixing component 13 is provided inside the moving groove 12. The fixing component 13 includes a spring 1301 and a fixing block 1302. The end of the spring 1301 is provided with the fixing block 1302. The two end faces of the fixing block 1302 are both inclined. The shape and position of the fixing block 1302 are adapted to the fixed groove 14. When the slider 7 moves, since the two sides of the fixing block 1302 are inclined planes, the fixing block 1302 is squeezed into the moving groove 12 by the slider 7, squeezing the spring 1301. When reaching near the fixed groove 14, the fixing block 1302 is snapped into the fixed groove 14 under the push of the spring 1301, realizing the fixation of the slider 7 and the locking of the safety cover 8. A travel switch 5 is provided on the surface of the gun body 1. An indicator light 6 is provided on the surface of the gun body 1. The travel switch 5 is electrically connected to the indicator light 6, and the position of the travel switch 5 is adapted to the slider 7. When the slider 7 moves to a specific position, the travel switch 5 is triggered, thereby lighting up the indicator light 6, sending a signal to the user that the charging is ready.

[0028] When charging, the staff only need to long-press the fingerprint recognition area 16 with their finger or use an NFC device to scan it once in the NFC reading area 15 to quickly verify the identity information. Once the verification is passed, the control main board 9 immediately sends an instruction to cut off the power supply of the electromagnet 10, so that the safety cover 8 can be opened. Then, the slider 7 slides along the preset chute 4. Finally, the slider 7 slides to the designated position, and the fixed block 1302 is squeezed into the movable slot 12 by the slider 7, squeezing the spring 1301. When it reaches near the fixed slot 14, the fixed block 1302 is pushed by the spring 1301 and snaps into the fixed slot 14, realizing the fixation of the slider 7 and the locking of the safety cover 8. At the same time, the slider 7 will trigger the travel switch 5, and then the indicator light 6 will be lit, conveying a signal that charging is possible to the user. Then the user can insert the charging male head 2 into the charging female head 3 for charging. After charging is completed, slide the slider 7 in the reverse direction. Since both sides of the fixed block 1302 are inclined planes, the fixed block 1302 is squeezed into the movable slot 12 by the slider 7, squeezing the spring 1301, releasing the slider 7 from the fixing assembly 13, and returning it to its original position along the chute 4 to close the safety cover 8. The staff only need to tap the fingerprint recognition area 16 twice continuously or swipe the NFC reading area 15 twice continuously to trigger another instruction of the control main board 9, that is, to energize the electromagnet 10, and tightly fix the safety cover 8 and the charging male head 2 through the suction force between the electromagnet 10 and the iron block 11, effectively preventing unauthorized personnel from randomly opening the cover of the charging port, and significantly enhancing the safety performance of the charging port with a cover structure. Specific Embodiment 2:

[0030] On the premise of meeting the above structure, a wireless communication module can be set in the control main board 9 to realize remote control between the control main board 9 and the mobile phone APP. Users can remotely unlock the charging port, view the charging status, receive charging completion notifications, etc. through the mobile phone APP. At the same time, the system can also monitor the safety status of the charging port in real time. When it detects an attempt by unauthorized personnel to open the charging port, the system will automatically send a text message notification to notify the management staff to handle it in time.

[0031] In summary:

[0032] 1. The NFC reading area 15, fingerprint recognition area 16, electromagnet 10, slider 7, fixed component 13, travel switch 5 and indicator light 6 are adopted. When charging, the staff only needs to long-press the fingerprint recognition area 16 with a finger or use an NFC device to scan the NFC reading area 15 once, then the rapid verification of identity information can be completed. Once the verification is passed, the control main board 9 immediately sends an instruction to cut off the power supply of the electromagnet 10, so that the safety cover 8 can be opened. Subsequently, the slider 7 slides along the preset chute 4. Finally, the slider 7 slides to the specified position and is fixed by the fixed component 13. At the same time, the slider 7 triggers the travel switch 5, and then the indicator light 6 is lit to convey a signal to the user that charging is possible. After charging is completed, the slider 7 is released from the fixed component 13 and returns to its original position along the chute 4 to close the safety cover 8. The staff only needs to tap the fingerprint recognition area 16 twice continuously or swipe the NFC reading area 15 twice continuously to trigger another instruction of the control main board 9, that is, to energize the electromagnet 10. Through the suction force between the electromagnet 10 and the iron block 11, the safety cover 8 and the charging male head 2 are tightly fixed, effectively preventing unauthorized personnel from randomly opening the cover of the charging port, and significantly enhancing the safety performance of the charging port with a cover structure.
