Furthermore, the long-term exposure of charging cables to the environment can shorten their lifespan. In special circumstances, because the charging cable operates at a non-safe voltage, insulation damage can lead to insulation abnormalities and other safety hazards, potentially causing electric shocks if undetected.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0032] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0033] Figure 1 This is a schematic diagram of the structure of an automatic charging gun cable retraction and extension control system provided in an embodiment of this utility model, as shown below. Figure 1As shown, the automatic rewind and unwind control system for the charging gun cable includes: a manual mode signal output module 10, an automatic mode signal output module 20, a communication module 30, a cable winding control module 40, a motor module 50, and a motor Hall signal detection module 60; the manual rewind and unwind trigger signal output terminal of the manual mode signal output module 10 is electrically connected to the manual rewind and unwind trigger signal receiving terminal of the cable winding control module 40; the Hall signal output terminal of the motor Hall signal detection module 60 is connected to the Hall signal detection terminal of the cable winding control module 40; the Hall signal detection terminal of the motor Hall signal detection module 60 is electrically connected to the motor module 50; the automatic rewind and unwind trigger signal output terminal of the automatic mode signal output module 20 is connected to the automatic rewind and unwind trigger signal receiving terminal of the cable winding control module 40 through the communication module 30; the output terminal of the cable winding control module 40 is electrically connected to the drive terminal of the motor module 50.

[0034] Among them, the manual mode signal output module 10 is a module that converts and outputs signals according to different operation commands of the user; the automatic mode signal output module 20 is a module that converts and outputs signals according to automatically received commands; the automatically received commands can be the sensor signal commands after the charging gun is inserted into the charging dock; or the sensor signal commands after the charging gun is plugged into or unplugged from the charging dock; the cable reel control module 40 can be a cable reel controller.

[0035] Specifically, the control process of the automatic rewinding and unwinding control system for the charging gun cable is as follows: when the charging gun is placed in the charging base, the automatic mode signal output module 20 outputs an automatic rewinding trigger signal, and the rewinding control module 40 drives the motor module 50 to work according to the received automatic rewinding trigger signal, thereby driving the rewinding spool to rewind the cable; or after the manual mode signal output module 10 outputs a manual rewinding trigger signal, the rewinding control module 40 drives the motor module 50 to work according to the received manual rewinding trigger signal, thereby driving the rewinding spool to rewind the cable.

[0036] When the charging gun is removed from the charging dock, the automatic mode signal output module 20 outputs an automatic cable release trigger signal. The cable reel control module 40 then drives the motor module 50 to operate based on the received automatic cable release trigger signal, thereby causing the motor module 50 to drive the cable reel to release the cable to a preset length. Alternatively, the manual mode signal output module 10 outputs a manual cable release trigger signal. The cable reel control module 40 then drives the motor module 50 to operate based on the received manual cable release trigger signal, thereby causing the motor module 50 to drive the cable reel to release the cable to a preset length. If the charging gun is still some distance from the charging port after cable release stops, the user may pull the charging cable, causing the motor module 50 to rotate. In this case, the Hall signal detection module 60 can detect the Hall signal output by the motor module 50, and the cable reel control module... The 40th module controls the motor module 50 to drive the reel for wire winding and unwinding, as well as the length of the winding and unwinding, based on the Hall signal to meet the charging port distance requirements. Specifically, when the Hall signal changes from small to large, the motor module 50 drives the reel to continue unwinding and controls the unwinding length; when the Hall signal changes from large to small, the motor module 50 drives the reel to wind up and controls the winding length. This achieves manual and automatic multi-mode automatic winding and unwinding of the charging gun cable. Furthermore, after the preset unwinding length, the motor Hall signal detection module 60 flexibly adjusts the winding and unwinding, meeting the efficient and convenient charging requirements of the charging pile, improving the intelligence level of the charging pile, and avoiding the problems of low charging gun cable life and electric shock accidents caused by the inability to automatically wind up cables in existing technologies.

[0037] Optionally, the control process can be further optimized in the above embodiments. Figure 2 This is a schematic diagram of another automatic charging cable retraction and extension control system provided in this embodiment of the utility model, as shown below. Figure 2 As shown, the manual start / stop control signal output terminal of the manual mode signal output module 10 is electrically connected to the manual start / stop control signal receiving terminal of the winding control module 40; the automatic start / stop control signal output terminal of the automatic mode signal output module 20 is electrically connected to the automatic start / stop control signal receiving terminal of the winding control module 40 through the communication module 30; and the speed signal adjustment output terminal of the automatic mode signal output module 20 is electrically connected to the speed adjustment signal receiving terminal of the winding control module 40 through the communication module.

[0038] In the above embodiment, during the cable winding and unwinding process, a start / stop control signal can be output to the cable winding control module 40 via the manual mode signal output module 10 or the automatic mode signal output module 20. This allows the cable winding control module 40 to drive the motor module 50 to stop working. Alternatively, a speed adjustment signal can be output to the cable winding control module 40 via the automatic mode signal output module 20. This allows the cable winding control module 40 to control the winding and unwinding speed of the motor module 50 driving the cable reel. This addition of multi-mode start / stop control and speed adjustment control further enhances the automatic winding and unwinding function of the charging cable, increases the flexibility of automatic winding and unwinding, meets different user needs, and provides a better user experience.

[0039] Optionally, the modules in the above embodiments can be further refined. Figure 3 This is a schematic diagram of another automatic charging cable retraction and extension control system provided in this embodiment of the utility model, as shown below. Figure 3 As shown, the manual mode signal output module 10 includes: a switching unit 11; the switching unit 11 is used to switch the signal content of the manual retraction trigger signal output terminal and the manual start / stop control signal output terminal of the manual mode signal output module.

[0040] The switching unit 11 can be a push-button switch or a proximity switch. The winding control module 40 can receive manual start / stop control signals and manual winding / unwinding trigger signals according to the different switching port states of the switching unit 11. The winding control module 40 controls the motor module 50 to start and stop the winding reel according to the manual start / stop control signal, and controls the motor module 50 to wind and unwind the winding reel according to the manual winding / unwinding trigger signal, thus realizing the winding and unwinding function in manual mode.

[0041] Optional, continue to refer to Figure 3 The automatic mode signal output module 20 includes a host computer, a charging pile ECU unit, or a mobile application device (not shown). The host computer, charging pile ECU unit, or mobile application device can function as the automatic mode signal output module 20, outputting automatic start / stop control signals, manual winding / unwinding trigger signals, and speed adjustment signals. These signals are then transmitted to the winding control module 40 via the communication module 30. The winding control module 40, based on the automatic start / stop control signals, manual winding / unwinding trigger signals, and speed adjustment signals, controls the motor module 50 to start / stop the winding reel, controls the motor module 50 to wind and unwind the wire, and controls the motor module 50 to wind and unwind the wire at a preset speed. It is understood that this embodiment does not limit the specific type of the automatic mode signal output module 20.

[0042] Optional, continue to refer to Figure 3When the automatic mode signal output module 20 includes a host computer or a charging pile ECU unit, the communication module 30 includes an RS485 communication unit or a CAN communication unit. When the automatic mode signal output module 20 includes a mobile application device (such as a mobile phone, iPad, or smartwatch), as an optional embodiment, the communication module 30 may include a wireless communication unit (such as a WiFi module, Bluetooth, or cellular network); as another optional embodiment, instructions issued by the mobile application device may also be transmitted to the cable reel control module 40 via the host computer or the charging pile ECU unit. It is understood that this embodiment does not limit the specific type of the communication module 30.

[0043] Optionally, based on the above embodiments, the control system can be further optimized. Figure 4 This is a schematic diagram of another automatic charging cable retraction and extension control system provided in this embodiment of the utility model, as shown below. Figure 4 As shown, the control system also includes: a power conditioning module 70; the input terminal of the power conditioning module 70 is electrically connected to the constant voltage power supply module VCC; the output terminal of the power conditioning module 70 is electrically connected to the power supply terminal of the winding control module 40, the power supply terminal of the motor module 50, and the power supply terminal of the communication module 30.

[0044] The power adjustment module can adjust the output voltage of the constant voltage power supply module VCC according to the power supply voltage of the winding control module 40, motor module 50 and communication module 30 in different control systems. This enables compatible access to control systems with different power supply requirements, thereby driving the winding reel to rotate and realizing automatic winding and unwinding of the cable. This avoids the problem of incompatibility between different control systems in the prior art. For example, a 9-32V control system can be developed using the power adjustment module.

[0045] Optional, continue to refer to Figure 4 The control system also includes a braking module 80; the braking module 80 is connected in parallel with the power conditioning module 70 to absorb the back electromotive force of the motor module 50.

[0046] The braking module 80 can be a braking resistor component or a braking capacitor component. The braking module 80 can absorb the voltage output from the power regulation module 70 to the motor module 50, thereby reducing or eliminating the back electromotive force generated by the motor module 50. This reduces the back electromotive force generated by the motor module 50 from damaging or falsely triggering other related power supply equipment (such as the communication module 30 and the winding control module 40).

[0047] Optional, continue to refer to Figure 4The control system also includes: a motor current signal detection module 90; the input terminal of the motor current signal detection module 90 is electrically connected to the motor module 50; the current signal output terminal of the motor current signal detection module 90 is electrically connected to the current signal detection terminal of the winding control module 40; and the fault detection output terminal of the winding control module 40 is electrically connected to the fault receiving terminal of the automatic mode signal output module 20 through the communication module 30.

[0048] The winding control module 40 can store and output an alarm signal based on whether the current signal exceeds a preset current threshold, and upload the fault signal to the automatic mode signal output module 20 through the communication module 30. Alternatively, it can calculate the rotation speed based on the Hall signal, and store and output an alarm signal to the automatic mode signal output module 20 when the rotation speed exceeds a preset rotation speed threshold. This allows users to monitor the working status at any time, quickly lock the status of the winding reel, and help with the analysis and troubleshooting of problems.

[0049] Optional, Figure 5 This is a schematic diagram of another automatic charging cable retraction and extension control system provided in this embodiment of the utility model, as shown below. Figure 5 As shown, the control system also includes a remote upgrade module 100; the remote upgrade module 100 is electrically connected to the winding control module 40.

[0050] Specifically, in some embodiments, the remote upgrade module 100 communicates with the winding control module 40 via a serial port, or connects to the winding control module 40 via communication interfaces such as USB, SPI, IIC, and CAN. The remote upgrade module 100 loads the latest application or firmware and loads it into the winding control module 40 through the Bootload within the winding control module 40 according to a customized communication handshake process; thus realizing the OTA remote method.

[0051] In other embodiments, the remote upgrade module 100 may be integrated into the communication module 20, and the automatic mode signal output module 20 may also load the latest application or firmware. The control system obtains the latest application or firmware from the automatic mode signal output module 20 through the communication module 30, and loads it into the cable control module 40 according to a customized communication handshake process through the Bootload in the cable control module 40. This realizes the OTA remote mode. This embodiment does not limit the implementation of the OTA remote mode.

[0052] In this way, the software of the reel control module 40 distributed in different regions can be upgraded through the remote upgrade module 100, avoiding the need for after-sales personnel to travel back and forth; at the same time, firmware upgrades and vulnerability fixes of the reel control module 40 can also be performed to achieve iterative upgrades of the reel function, further improving the intelligence level of the control system.

[0053] Based on the same inventive concept, this utility model embodiment also provides a charging gun cable reel. Figure 6 This is a top view of a charging gun cable reel provided in an embodiment of the present invention; Figure 7 This is a side view of a charging gun cable reel according to an embodiment of the present invention; as shown. Figure 6-7 As shown, the charging gun cable reel 001 includes the automatic charging gun cable winding and unwinding control system 01 and the reel body 02 described in the above embodiment; the drive end of the motor module in the automatic charging gun cable winding and unwinding control system 01 is electrically connected to the reel body 02. Since this embodiment includes an automatic charging gun cable winding and unwinding control system, it also has the beneficial effects of the above embodiments, which will not be described again here.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
