The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and thus are only examples and cannot be used to limit the protection scope of the present application.

In the description of the embodiments of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0036] Please refer to Figure 1 , Figure 1Schematic diagram of the structure of a charging temperature measurement module 01 provided by an embodiment of the present application. The charging temperature measurement module 01 is used for a charging gun and includes: a thermistor temperature sensor 10;

[0037] The thermistor temperature sensor 10 and the micro switch 20 are integrated on the same circuit board, and the thermistor temperature sensor 10 is electrically connected to the charging pile main board.

[0038] Among them, the thermistor temperature sensor 10 can be implemented by a metal thermistor (for example, a platinum thermistor or a copper thermistor, etc.) or a semiconductor thermistor (for example, a negative temperature coefficient thermistor or a positive temperature coefficient thermistor, etc.). When the charging gun is successfully inserted into the charging interface of the charging vehicle, the micro switch 20 can be activated and send a signal to start charging to the charging pile; when charging is completed or the charging gun is pulled out, the micro switch 20 can notify the charging pile to stop charging to ensure the safety of the charging vehicle and the charging device. The electrical connection between the thermistor temperature sensor 10 and the charging pile main board can be achieved through a conventional wire. By welding one end of the wire to one end of the thermistor temperature sensor 10, the electrical connection between one end of the wire and the thermistor temperature sensor 10 is realized, and then the other end of the wire is welded to the temperature monitoring port on the charging pile main board to realize the electrical connection between the other end of the wire and the charging pile main board; thus, the electrical connection between the thermistor temperature sensor 10 and the charging pile main board is realized based on this wire.

[0039] Among them, the micro switch 20 is usually arranged at the gun head position of the charging gun. The present application ingeniously integrates the thermistor temperature sensor 10 and the micro switch 20 on the same circuit board, thereby reducing the installation complexity of the corresponding charging gun and improving the production efficiency of the charging gun.

[0040] It can be seen that the charging temperature measurement module 01 provided by the embodiment of the present application includes a thermistor temperature sensor 10, and the thermistor temperature sensor 10 and the micro switch 20 are integrated on the same circuit board; based on this charging temperature measurement module 01, the installation of the thermistor temperature sensor 10 can be realized while installing the micro switch 20; then, the electrical connection between the thermistor temperature sensor 10 and the charging pile main board is realized through a wire. It is convenient for the charging pile main board to monitor the temperature of the gun head pin of the charging gun based on the thermistor temperature sensor 10, and when the charging temperature is too high, adjust the charging parameters based on the charging pile main board to ensure the safety and efficiency of the charging process. Therefore, the installation process of the charging temperature measurement module 01 provided by the present application is simpler, the installation difficulty of the corresponding charging gun can be reduced, and the production efficiency can be improved. It solves the technical problem that the installation of the existing charging temperature measurement module is cumbersome, resulting in low production efficiency of the charging gun.

[0041] In addition, based on the existing installation method of the temperature sensor, after crimping the end of the thermocouple temperature measurement wire, sleeving it with a heat shrink tube, and then plugging it into the charging pile main board, a micro switch still needs to be assembled. However, the technical solution provided in this application can simultaneously install the thermistor temperature sensor 10 and the micro switch 20. Based on the charging temperature measurement module 01 provided in this application, the installation production line working hours of the thermistor temperature sensor 10 and the micro switch 20 can be significantly reduced, and the production efficiency of the corresponding charging gun can be improved.

[0042] Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of another charging temperature measurement module 01 provided by an embodiment of this application. It should be noted that Figure 2 The left side specifically shows a schematic structural diagram of the charging temperature measurement module 01 on the welding surface of the circuit board, Figure 2 and the right side specifically shows a schematic structural diagram of the charging temperature measurement module 01 on the component surface of the circuit board.

[0043] In some optional embodiments, the charging temperature measurement module 01 further includes: a first socket 30; the first socket 30 is plugged into the welding surface of the circuit board, and the first socket 30 is electrically connected to the thermistor temperature sensor 10; wherein, the thermistor temperature sensor 10 is configured to be electrically connected to the charging pile main board based on a signal wire inserted into the first socket 30.

[0044] Among them, the first socket 30 can be implemented by a socket into which one or more circuit wiring can be inserted. Through the first socket 30, a signal wire can be inserted, and the electrical connection between the thermistor temperature sensor 10 and the charging pile main board can be realized based on the inserted signal wire. By plugging the first socket 30 into the welding surface of the circuit board and electrically connecting the first socket 30 to the thermistor temperature sensor 10, it is convenient to connect the thermistor temperature sensor 10 to other circuits (in this application, it is the charging pile main board). The circuit board can include a component surface and a welding surface. The component surface refers to the side of the circuit board used to install components, and the welding surface refers to the side used for wiring and realizing the electrical connection between components.

[0045] Among them, the thermistor temperature sensor 10 and the signal wire inserted into the first socket can be electrically connected through the first socket 30, and then the signal wire inserted into the first socket 30 is electrically connected to the charging pile main board, thereby realizing the electrical connection between the thermistor temperature sensor 10 and the charging pile main board. Based on the first socket 30, the installation process of the charging temperature measurement module 01 can be made simpler, and the production efficiency of the charging gun can be further improved.

[0046] In some alternative embodiments, the charging temperature measurement module 01 further includes: a CC resistor 40 integrated on the same circuit board; one end of the CC resistor 40 is electrically connected to the common terminal of the microswitch 20, the middle end is electrically connected to the normally open / normally closed terminal of the microswitch 20, and the other end is electrically connected to the CC pin.

[0047] Among them, the microswitch 20 is usually implemented by a three-pin microswitch, specifically including three pin terminals, namely a common terminal, a normally open terminal, and a normally closed terminal. The CC resistor 40 can be implemented by a sliding rheostat or by two first resistors and a second resistor connected in series. Exemplarily, in the case where the CC resistor 40 is implemented by a sliding rheostat, the sliding end of the sliding rheostat can be used as the middle end of the CC resistor 40 and electrically connected to the normally open / normally closed terminal of the microswitch 20; the two fixed ends of the sliding rheostat are respectively electrically connected to the common terminal of the microswitch 20 and the CC pin. By integrating the CC resistor 40 and the microswitch 20 on the same circuit board, the installation of the thermistor temperature sensor 10 and the CC resistor 40 can be realized while installing the microswitch 20; further reducing the installation difficulty of the corresponding charging gun and improving the production efficiency.

[0048] In some alternative embodiments, the charging temperature measurement module 01 further includes: a second socket 50; the second socket 50 is plugged into the welding surface of the circuit board, and the second socket 50 is electrically connected to the other end of the CC resistor 40; wherein, the other end of the CC resistor 40 is configured to be electrically connected to the CC pin based on the signal line inserted into the second socket 50.

[0049] Among them, the specific implementation manner of the second socket 50 and the specific implementation manner of the first socket 30 may be the same or different. The second socket 50 can be implemented by a socket into which one or more circuit wiring can be inserted. The signal line can be inserted through the second socket 50, and the electrical connection between the other end of the CC resistor 40 and the CC pin can be realized based on the inserted signal line. By plugging the second socket 50 into the welding surface of the circuit board and electrically connecting the second socket 50 to the other end of the CC resistor 40, it is convenient to connect the other end of the CC resistor 40 to other circuits (the CC pin in this application). The other end of the CC resistor 40 and the signal line inserted into the second socket 50 can be electrically connected through the second socket 50, and then the electrical connection between the other end of the CC resistor 40 and the CC pin can be realized by electrically connecting the signal line inserted into the second socket 50 to the CC pin. Based on the second socket 50, the installation process of the charging temperature measurement module 01 can be made simpler, further improving the production efficiency of the charging gun.

[0050] In some alternative embodiments, the CC resistor 40 includes a first resistor 401 and a second resistor 402; one end of the first resistor 401 is electrically connected to the common terminal of the microswitch 20, and the other end is electrically connected to one end of the second resistor 402; one end of the second resistor 402 is also electrically connected to the normally open / normally closed terminal of the microswitch 20, and the other end is electrically connected to the CC pin.

[0051] Wherein, the resistance value of the first resistor 401 can be 220Ω or other reasonable values. Correspondingly, the resistance value of the second resistor 402 can be 3300Ω or other reasonable values. When the microswitch 20 is closed, both the first resistor 401 and the second resistor 402 are connected to the CC signal circuit. When the microswitch 20 is open, only the first resistor 401 is connected to the CC signal circuit. Therefore, by toggling the microswitch 20, the resistance value of the CC resistor 40 connected can be changed, that is, the electrical signal at the CC pin can be changed. Furthermore, the switch state of the microswitch 20 can be associated with the charging mode of the charging pile (exemplarily, it can include fast charging mode and slow charging mode), that is, the charging mode can be switched by toggling the microswitch 20. Since the resistance value of the CC resistor connected to the CC signal circuit will also change when the switch state of the microswitch 20 changes, the change of the CC signal can be sent to the CC port of the charging vehicle through the CC pin, so that the charging vehicle can identify the current charging mode according to the change of the CC signal.

[0052] In some alternative embodiments, the thermistor temperature sensor 10 includes an NTC thermistor.

[0053] Among them, the NTC thermistor has good stability, low drift and good long-term stability; even in a high-temperature environment, the NTC thermistor can maintain stable performance and can achieve long-term and reliable monitoring of the temperature of the pin of the charging gun head.

[0054] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of a charging gun 02 provided by an embodiment of the present application. As Figure 3 shown, an embodiment of the present application further provides a charging gun 02, including: a charging housing 021, a plurality of gun head pins 022 arranged in the charging housing 021, and a charging temperature measurement module 01 as described in any one of the above first aspects arranged in the charging housing 021.

[0055] Among them, the gun head pin 022 can specifically include a CC pin terminal (responsible for charging connection and confirmation of the charging mode), a CP terminal (used to confirm the maximum charging current that the current power supply device can support), an L terminal (representing the AC power supply), an N terminal (representing the neutral line), a PE terminal (protective ground wire, used to ensure the safety of the charging process), etc. It can be understood that the number of gun head pins 022 can be adjusted according to actual application requirements. The number of gun head pins 022 included in different types of charging guns 02 can be the same or different. The charging temperature measurement module 01 can be specifically arranged around the gun head pin 022 or between multiple gun head pins 022. This application does not make specific limitations in this regard. It should be understood that this charging gun 02 corresponds to the above-mentioned embodiment of the charging temperature measurement module 01. The specific implementation method of this charging gun 02 can refer to the relevant description of the charging temperature measurement module 01 in the above text. To avoid repetition, the detailed description is appropriately omitted here.

[0056] In some alternative embodiments, the charging temperature measurement module 01 is specifically arranged around the gun head pin 022, and the component surface of the circuit board integrating the thermistor temperature sensor 10 and the micro switch 20 is arranged close to the gun head pin 022.

[0057] Among them, by arranging the charging temperature measurement module 01 around the gun head pin 022 and arranging the component surface of the circuit board integrating the thermistor temperature sensor 10 and the micro switch 20 close to the gun head pin 022, the installation difficulty of the charging temperature measurement module 01 can be reduced while the distance between the thermistor temperature sensor 10 and the gun head pin 022 of the charging gun 02 can be shortened as much as possible to improve the temperature perception sensitivity of the thermistor temperature sensor 10 to the gun head pin 022 of the charging gun 02.

[0058] Please refer to Figure 4 , Figure 4 which is a schematic structural diagram of another charging gun 02 provided by the embodiment of the present application. It should be noted that Figure 4 shows a partial structural diagram of the charging gun 02, and specifically shows a partial structural diagram in the case where the charging temperature measurement module 01 is inserted into the temperature measurement installation groove 023.

[0059] In some alternative embodiments, a temperature measurement installation groove 023 is provided on the inner side wall of the charging housing 021; the charging temperature measurement module 01 is configured to be inserted into the temperature measurement installation groove 023 to achieve the installation of the charging temperature measurement module 01.

[0060] Among them, the temperature measurement installation groove 023 can be fixed on the inner side wall of the charging housing 021 by a snap - connection method; or the charging housing 021 with the temperature measurement installation groove 023 provided on its inner side wall can be directly produced by an integral injection molding method; this application does not make specific limitations in this regard. The size of the inner space of the temperature measurement installation groove 023 can be adjusted according to the size of the actual charging temperature measurement module 01. By providing the temperature measurement installation groove 023 on the inner side wall of the charging housing 021, only by inserting the charging temperature measurement module 01 into the temperature measurement installation groove 023, the installation of the charging temperature measurement module 01 can be achieved, further reducing the installation difficulty of the corresponding charging gun 02 and improving the production efficiency.

[0061] In some alternative embodiments, a temperature measurement opening is provided on the side of the temperature measurement installation groove 023 close to the gun head pin 022; when the charging temperature measurement module 01 is installed, the thermistor temperature sensor 10 of the charging temperature measurement module 01 is configured to be in the opening area of the temperature measurement opening.

[0062] Among them, "when the charging temperature measurement module 01 is installed, the thermistor temperature sensor 10 of the charging temperature measurement module 01 is configured to be in the opening area of the temperature measurement opening" means that: when the charging temperature measurement module 01 is installed, the thermistor temperature sensor 10 can directly measure the charging temperature of the corresponding gun head pin 022 through the temperature measurement opening, and the groove wall of the temperature measurement installation groove 023 will not affect the temperature measurement of the thermistor temperature sensor 10. The opening position or the opening size of the temperature measurement opening can be adjusted according to parameters such as the setting position of the thermistor temperature sensor 10 on the actual charging temperature measurement module 01 or the actual size of the thermistor temperature sensor 10. By providing a temperature measurement opening on the side of the temperature measurement installation groove 023 close to the gun head pin 022 and placing the thermistor temperature sensor 10 in the opening area of the temperature measurement opening when the charging temperature measurement module 01 is installed, the thermistor temperature sensor 10 can sensitively sense the temperature change of the gun head pin of the charging gun 02, facilitating the charging pile main board to react promptly to the abnormal charging temperature situation and improving the safety of the charging process.
