The heat-conducting box 9 is made of a heat-conducting material, such as polyetheretherketone (PEEK), which is existing technology; the heat-conducting coating 18 is made of a heat-conducting material, such as alumina, which is existing technology; the heat-conducting adhesive 15 is a curable silicone heat-conducting adhesive, which is existing technology.

[0026] Specifically, after the device has been running for a certain period of time, the heat generated by the control unit 17 is conducted through the thermally conductive adhesive 15 to the thermally conductive coating 18 on the inner wall of the heat-conducting box 9, and then the thermally conductive coating 18 conducts the heat to the heat-conducting box 9. The heat is then radiated outwards through the thermally conductive coating 18 on the outer wall of the heat-conducting box 9, and the heat dissipation efficiency is improved through the heat dissipation fins 10. The vent 12 balances the internal and external pressures, further assisting in the heat dissipation of the control unit 17.

[0027] The cooling fan 5 draws out air and heat from inside the handle housing 6, while fresh air enters through the air inlet 20, achieving rapid airflow and improving heat dissipation efficiency. This addresses the issue of overheating and subsequent disconnection of the charging gun due to poor heat dissipation caused by prolonged high-current charging of the internal electronic components.

[0028] ReferenceFigure 1 A terminal housing 3 is fixedly connected to the left side of the handle housing 6, and a connector 1 and a locking component 2 are fixedly connected to the right side of the terminal housing 3. The outer wall of the connector 1 passes through the left side of the terminal housing 3, and the locking component 2 is located above the connector 1.

[0029] Specifically, the locking component 2 is a mechanical structure, which is existing technology; the connector 1 is used to engage with the car charging port for power supply; when the connector 1 is inserted into the car charging port, the left side of the locking component 2 slides into the groove of the car charging port, thus completing the fixation and locking of the device; when charging is started, the charging function of the device is realized.

[0030] Reference Figure 1 A locking button 4 is provided on the upper side of the terminal housing 3. The outer wall of the locking component 2 passes through the left side of the terminal housing 3, the outer wall of the locking button 4 passes through the upper side of the terminal housing 3, and the right side of the locking component 2 is connected to the lower side of the locking button 4.

[0031] Specifically, after charging is complete, pressing the locking button 4 causes the left side of the locking component 2 to lift up, releasing the device from the car charging port. Pulling the device outwards then unlocks the device.

[0032] Reference Figure 1 A cable 7 is provided on the right side of the handle housing 6, and the outer wall of the cable 7 passes through the right side of the handle housing 6.

[0033] Specifically, the device is powered via cable 7, which helps to enable the device to be charged.

The lower end of the fixing bolt 14 is threaded to the inner wall of the handle housing 6.

[0036] Reference Figure 3 The control unit 17 is provided with a fixing bolt 2 16, the lower end of which is threaded to the inner bottom wall of the heat conduction box 9.

[0037] Specifically, the control unit 17 is fixed inside the heat-conducting box 9 by fixing bolt 2 16, thereby achieving the fixation of the control unit 17.

[0038] Reference Figure 5The outer wall of the handle housing 6 is provided with a breathable membrane 19, which is fixedly connected to the inner wall of the air inlet 20.

[0039] Specifically, the breathable membrane 19 has breathable, waterproof, and dustproof functions and can be made of polytetrafluoroethylene. When external air enters the handle housing 6 through the air inlet 20, large particles such as dust in the air are intercepted by the breathable membrane 19, thereby achieving the effects of dustproof, waterproof, and breathable inside the handle housing 6.

[0040] Reference Figures 1-3 Connector 1 and terminal interface 8 are electrically connected. Terminal interface 8, lower interface 11, and cooling fan 5 are all electrically connected to control unit 17. Lower interface 11 is electrically connected to cable 7.

[0041] Specifically, when using this device, connector 1 is inserted into the car's charging port, and power is supplied to control unit 17 through cable 7 and lower interface 11. After processing by control unit 17, power is transmitted to connector 1 through terminal interface 8, and then the car is charged through connector 1. Control unit 17 controls the operation of cooling fan 5, which allows the air inside handle housing 6 to circulate quickly and carry away heat, thereby achieving the heat dissipation effect of the device.

[0042] Working principle: When using this device, insert connector 1 into the car charging port, and locking component 2 locks the car charging port; power is supplied to control unit 17 through cable 7 and lower interface 11; after processing by control unit 17, power is transmitted to connector 1 through terminal interface 8, and then the car is charged through connector 1.

[0043] After the device has been running for a certain period of time, the heat generated by the control unit 17 is conducted through the thermally conductive adhesive 15 to the thermally conductive coating 18 on the inner wall of the heat-conducting box 9, and then through the thermally conductive coating 18 to the heat-conducting box 9. The heat is then radiated outwards through the thermally conductive coating 18 on the outer wall of the heat-conducting box 9, and the heat dissipation area is increased by the heat dissipation fins 10. The vent 12 balances the pressure inside and outside the heat-conducting box 9, protecting the seal of the thermally conductive adhesive 15 on the control unit 17.

[0044] Simultaneously, the control unit 17 controls the operation of the cooling fan 5, and through the air intake vent 20, enables rapid airflow inside the handle housing 6, carrying away the heat inside the handle housing 6. This improves the problem of the charging gun's internal electronic components overheating during prolonged high-current charging and the resulting disconnection due to poor heat dissipation.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
