[0057] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0058] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0059] The applicant of this application found in the actual research process that with the rapid development of electric vehicles in recent years, large-scale fast charging and super charging systems are also constantly developing. These systems require the use of thicker and heavier charging cables to connect charging piles to meet the needs of high charging power.

[0060] In the prior art, there are two ways to store charging cables. One is to hang the charging cable on the charging pile take-up rack, and the user manually adjusts the required length of the charging cable. The other is that the charging pile is equipped with an automatic cable retracting device. When the user uses it, the automatic cable retracting device automatically controls the retraction and extension of the charging cable through the plug-in and unplugging signals of the charging gun.

[0061] However, the charging cables required for large-scale fast charging or supercharging systems are heavy and difficult to store manually. Moreover, the outer periphery of the charging cables becomes very hard at low temperatures, which is not conducive to the user's storage. In addition, the charging cables are often placed on the ground, which not only causes chaos at the charging site, but also causes pollution and wear of the charging cables, thereby increasing the operating and maintenance costs. In addition, the charging piles with automatic retractable wire devices can only automatically retract and release the wires according to the plug-in and unplug signals at this stage, and cannot release the wires according to the distance between the electric vehicle and the charging pile, or the distance between the user and the charging pile. In this way, the automatic retractable wire device of the charging pile has the problem of too much charging cable falling to the ground or too much tightening, and cannot provide users with a good charging experience according to the specific application environment of the electric vehicle. Therefore, users have a poor charging experience when charging electric vehicles with charging piles.

[0062] In view of this, an embodiment of the present application provides a charging pile, which includes a charging pile body, a gun plug seat, a distance detection part, a retractable wire assembly, a charging gun, a charging gun wire and a control part. By arranging the gun plug seat, the distance detection part and the retractable wire assembly on the charging pile body, the retractable wire assembly and the distance detection part are electrically connected to the control part. When the user removes the charging gun from the gun plug seat, the distance detection part detects the distance between the user and the charging pile body in real time, and the control part controls the retractable wire assembly to retract and release the charging gun wire in real time according to the distance detected by the distance detection part, thereby improving the accuracy of the retractable wire assembly of the charging pile in retracting and releasing the charging gun wire, improving the intelligence level of the charging pile, and improving the performance of the charging pile. In addition, the charging pile solves the problem of the retractable wire assembly of the charging pile releasing more gun wires at one time, avoids the user adjusting the retractable length of the charging gun wire multiple times, avoids the problem of the charging gun wire dragging and wearing, improves the safety of the charging gun wire, improves the service life of the charging pile, and reduces the maintenance cost of the charging pile.

[0063] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0064] Reference Figures 1 to 4As shown, the present application provides a charging pile for charging a vehicle, the charging pile comprising a charging pile body 100, a gun socket 200, a distance detection component 300, a retractable wire assembly 400, a charging gun 500, a charging gun wire 600 and a control component 700, the gun socket 200, the distance detection component 300 and the retractable wire assembly 400 are all arranged on the charging pile body 100; the first end of the charging gun 500 is plug-in connected to the gun socket 200, and the second end of the charging gun 500 is connected to the charging pile body 100 through the charging gun wire 600.

[0065] The retractable wire assembly 400 and the distance detection component 300 are both electrically connected to the control component 700 ; the distance detection component 300 is configured to detect the distance between the user and the charging pile body 100 .

[0066] When the user removes the charging gun 500 from the gun socket 200 , the distance detection member 300 is configured to detect the distance between the user and the charging pile body 100 , and the control member 700 is configured to control the retractable wire assembly 400 to retract and release the charging gun wire 600 according to the distance.

[0067] For example, when a user uses a charging pile to charge a vehicle, when the user holds the charging gun 500 and moves away from the charging pile body 100, that is, when the user moves towards the vehicle, the distance detection component 300 obtains the real-time distance between the user and the charging pile body 100, and the control component 700 releases the charging gun line 600 of the corresponding length in real time according to the distance detected by the distance detection component 300, without the user returning to the charging pile body 100 to adjust the charging gun line 600; when the vehicle is charged, the user holds the charging gun 500 and moves it towards the charging pile body 100, that is, the user moves away from the vehicle. When moving in the direction, the distance detection component 300 obtains the distance between the user and the charging pile body 100, and the control component 700 retracts the charging gun line 600 of the corresponding length according to the distance detected by the distance detection component 300, without the need for the user to manually wind the charging gun line 600 onto the storage device. In this way, the control component 700 controls the retractable wire assembly 400 to retract and release the wire according to the distance detected by the distance detection component 300, thereby improving the accuracy of the charging pile retractable wire assembly 400 in retracting and releasing the charging gun wire 600, improving the user's charging efficiency, improving the intelligence level of the charging pile, and improving the performance of the charging pile.

[0068] When the user holds the charging gun 500 and moves away from or close to the charging pile body 100, the control component 700 controls the retractable wire assembly 400 to retract and release the charging gun wire 600 in real time according to the detection distance of the distance detection component 300, thereby avoiding the problem of the charging pile retractable wire assembly 400 releasing too many gun wires at one time, avoiding the problem of the charging gun wire 600 being worn out by dragging on the ground, and improving the safety of the charging gun wire 600. At the same time, it avoids the user from adjusting the retracted and released length of the charging gun wire 600 multiple times, thereby improving the service life of the charging gun wire 600 and reducing the maintenance cost of the charging gun wire 600.

[0069] For example, the control unit 700 may be a microcontroller unit (MCU), which is a microcontroller, a processor, capable of controlling the main components of the charging pile. The MCU includes a kernel, which can execute an operating system, some memory, and some interfaces for external devices.

[0070] Universal Asynchronous Receiver / Transmitter (UART) is a part of computer hardware that converts data between serial communication and parallel communication. It can be an independent modular chip or a peripheral device integrated into a microprocessor. Fig.12 As shown, Fig.12 This is the UART communication circuit diagram of the distance detection device. Fig.12 The dotted box 1 plays a role in stabilizing and filtering the input voltage. Fig.12 The dashed box 2 part monitors the output voltage. Fig.12 The dotted line frame 3 is the information exchange part of the distance detection element 300, wherein one branch can be used for the distance detection element 300 to read the signal, and the other branch can be used for the distance detection element 300 to output a corresponding signal according to the read signal.

[0071] As a feasible implementation method, refer to Figures 1 to 5 As shown, the retractable wire assembly 400 includes a push rod motor 401, a push rod 402 and at least one limit trigger component 403. The push rod 402 is connected to the push rod motor 401. The push rod motor 401 is used to drive the push rod 402 to move along a preset direction. The limit trigger component 403 is arranged on the charging pile body 100 and is located on the moving path of the push rod 402, and is used to limit the moving position of the push rod 402.

[0072] The charging gun wire 600 is movably connected to the push rod 402 and moves in conjunction with each other.

[0073] The limit trigger 403 and the push rod motor 401 are both electrically connected to the control component 700. When the limit trigger 403 is configured to contact the push rod 402, it sends a stop push rod movement signal to the control component 700. The control component 700 controls the push rod motor 401 to stop moving the push rod 402 according to the stop push rod movement signal.

[0074] In some embodiments, the retractable wire assembly 400 includes a push rod motor 401, a push rod 402 and a limit trigger 403. Among them, the push rod motor 401 is fixed to the bottom of the charging pile body 100, the push rod motor 401 and the first end of the push rod 402 are connected through a bearing, the second end of the push rod 402 extends along a preset direction, and the second end of the push rod 402 is movably connected to the charging gun line 600. In this way, when the charging gun 500 drives the push rod 402 to move along a preset direction, the charging gun line 600 movably connected to the second end of the push rod 402 moves toward or away from the vehicle to realize the retraction and release of the charging gun line 600.

[0075] By arranging a limit trigger component 403 on the charging pile body 100, and arranging the limit trigger component 403 on the moving path of the push rod 402, wherein the limit trigger component 403 can be arranged near the bottom of the charging pile body 100, when the push motor drives the push rod 402 to move along the preset direction, when the push rod 402 contacts the limit trigger component 403, the limit contact component sends a stop push rod movement signal to the control component 700, and the control component 700 controls the push rod motor 401 to stop moving the push rod 402 according to the stop push rod movement signal. In this way, the maximum value of the length of the charging gun line 600 that the retractable line assembly 400 retracts and releases is limited, and excessive release of the charging gun line 600 is avoided, thereby ensuring the effective connection between the charging gun line 600 and the charging pile body 100, avoiding damage to the charging gun line 600 and the charging pile body 100 caused by artificial pulling of the charging gun line 600, and reducing the maintenance cost of the charging pile.

[0076] For example, the preset direction may be a vertical direction or other directions, and the present application does not limit the moving direction of the push rod 402 .

[0077] In other embodiments, the retractable wire assembly 400 includes a roller motor, a roller, and at least one limit trigger 403, wherein the charging gun wire 600 is wound around the outer peripheral wall of the roller. In the process of retracting and releasing the charging gun wire 600 of the retractable wire assembly, the roller motor drives the roller to rotate, for example, when the roller motor drives the roller to rotate clockwise, the roller releases the charging gun wire 600, and when the roller motor drives the roller to rotate counterclockwise, the roller retracts the charging gun wire 600, thereby achieving the purpose of automatically retracting and releasing the charging gun wire 600.

[0078] As a feasible implementation, a wire hole is provided on the push rod 402, and at least part of the charging gun wire 600 passes through the wire hole; the preset direction is the vertical direction, and the wire hole is located at the top of the push rod 402 along the vertical direction.

[0079] For example, when the wire retracting and releasing assembly 400 includes a push rod motor 401 and a push rod 402, and when the push rod 402 moves in a vertical direction, when the user holds the charging gun 500 and moves in different directions away from the charging pile body 100, the wire passing hole limits the movement range of the charging gun wire 600, thereby avoiding large-angle movement of the charging gun wire 600 connected to the second end of the push rod 402; by providing a wire passing hole at the second end of the push rod 402 and passing the wire passing hole through the middle section of the charging gun wire 600, the stability of the charging gun wire 600 during the retraction and releasing process is improved.

[0080] As a feasible implementation, the limit trigger component 403 includes two, namely a first limit trigger component 411 and a second limit trigger component 412. The first limit trigger component 411 and the second limit trigger component 412 are arranged on the charging pile body 100 at intervals along a preset direction, and a space for the push rod 402 to move is formed between the first limit trigger component 411 and the second limit trigger component 412.

[0081] For example, when the wire retracting assembly 400 includes a push rod motor 401 and a push rod 402, and the push rod 402 moves in the vertical direction, wherein the first limit trigger 411 is arranged near the bottom of the charging pile body 100, and the second limit trigger 412 is arranged near the top of the charging pile body 100, when the push rod motor 401 drives the push rod to move in the vertical direction, the push rod 402 moves in the vertical direction, and the first limit trigger 411 is arranged near the bottom of the charging pile body 100, and the second limit trigger 412 is arranged near the top of the charging pile body 100. Figure 1 When moving in the X1 direction, when the top of the push rod 402 contacts the first limit trigger 411, the first limit contact sends a stop push rod moving signal to the control component 700, and the control component 700 controls the push rod motor 401 to stop moving according to the stop push rod moving signal. At this time, the charging gun line 600 released by the retractable wire assembly 400 is the longest releasable charging gun line 600. By setting the first limit trigger 411 at a position close to the bottom of the charging pile body 100, it is avoided that the user pulls the charging gun line 600 due to the vehicle being too far away from the charging pile, thereby increasing the service life of the charging gun line 600 and reducing the management and maintenance costs of the charging pile.

[0082] When the push rod motor 401 drives the push rod 402 along Figure 1When moving in the X2 direction, when the top of the push rod 402 contacts the second limit trigger 412, the second limit contact sends a stop push rod movement signal to the control component 700, and the control component 700 controls the push rod motor 401 to stop moving according to the stop push rod movement signal. At this time, the retracting and releasing wire assembly 400 stores the charging gun wire 600. By setting the second limit trigger 412 on the top of the charging pile body 100, the charging gun wire 600 is stored, the space of the charging pile body 100 is reasonably utilized, and the problem of the charging gun wire 600 being idle on the ground after use is solved, and the loss caused by the friction between the charging gun wire 600 and the ground is avoided, the service life of the charging gun wire 600 is increased, and the cleanliness of the charging pile is improved.

[0083] For example, the first limit triggering member 411 may be a contact limit switch, and the second contact member may be a contact limit switch.

[0084] As a feasible implementation method, refer to Figure 2 and Figure 6 As shown, the charging pile further includes a gun seat light emitting component 800 , a light sensor 202 and a gun return detection component 201 , and the gun seat light emitting component 800 , the light sensor 202 and the gun return detection component 201 are all electrically connected to the control component 700 .

[0085] The light sensor 202 is configured to detect the ambient light brightness at the location of the charging pile body 100 .

[0086] The gun return detection member 201 is configured to detect whether the charging gun 500 is inserted into the gun socket 200 .

[0087] When the gun return detection component 201 detects that the charging gun 500 is inserted into the gun insertion seat 200, the distance detected by the distance detection component 300 is less than the preset distance value, and the light sensor 202 detects that the ambient light brightness is less than the preset brightness value, the control component 700 is configured to control the gun seat light emitting component 800 to emit light.

[0088] In some embodiments, reference Figure 7As shown, when the charging pile is in the night working state, when the user parks the vehicle at the designated location and is ready to use the charging pile to charge the vehicle, when the user gets off the vehicle and walks over to the charging pile body 100, the charging pile is in the original state, waiting to charge the vehicle. At this time, the charging gun 500 is inserted into the gun plug seat 200, and the gun return detection part 201 transmits the information that the charging gun 500 is located in the gun plug seat 200 to the control part 700; the light sensor 202 detects the ambient light brightness in real time and transmits the ambient light brightness information to the control part 700 in real time; the distance detection part 300 detects the distance between the user and the charging pile body 100 in real time, and transmits the distance information between the user and the charging pile body 100 to the control part 700 in real time. When the straight-line distance between the user and the charging pile body 100 is less than the preset distance value, and the ambient light brightness is less than the preset brightness value, the control part 700 controls the gun seat light emitting part 800 to emit light, thus avoiding the problem that the user cannot accurately find the charging gun 500 due to the dim ambient light brightness when using the charging pile at night, thereby improving the user experience. The ambient light brightness is sensed by the light sensor 202, the distance detection component 300 detects the distance between the user and the charging pile body 100, and the gun return detection component 201 detects whether the charging gun 500 is inserted into the gun socket 200. When the ambient light brightness is less than the preset brightness value, the distance between the user and the charging pile is less than the preset distance value, and the charging gun 500 is located in the gun socket 200, the gun socket luminous component 800 will emit light. In this way, while ensuring lighting for the user, the situation where the gun socket luminous component 800 is always on is avoided, saving electric energy.

[0089] In other embodiments, when the charging pile is in the night working state, when the charging pile completes charging the vehicle, the user needs to pull out the charging gun 500 from the vehicle charging port and insert it into the gun socket 200. At this time, the gun return detection component 201 transmits the information that the charging gun 500 is located in the gun socket 200 to the control component 700; the light sensor 202 detects the ambient light brightness in real time and transmits the ambient light brightness information to the real-time control component 700; the distance detection component 300 detects the distance between the user and the charging pile body 100 in real time and transmits the distance information between the user and the charging pile body 100 to the control component 700 in real time. When the straight-line distance between the user and the charging pile body 100 is less than the preset distance value and the ambient light brightness is lower than the preset brightness value, the control component 700 controls the gun socket light emitting component 800 to emit light, so that the user can be prompted to confirm that he has inserted the charging gun 500 into the gun socket 200 through the light of the gun socket light emitting component 800, thereby improving the user experience.

[0090] For example, the gun mount light emitting element 800 may be at least one of an incandescent lamp, a fluorescent lamp, a halogen tungsten lamp, a high pressure mercury lamp, and an LED (Light-Emitting Diode Light) lamp.

[0091] For example, the preset distance value may be 0.5 m.

[0092] Reference Fig.13 As shown, Fig.13 It is the Digital input (DI) detection circuit of the gun return detection component. Fig.13 The dotted line frame 1 and the dotted line frame 2 are connected via a photoelectric coupler. When the charging gun 500 is inserted into the gun socket 200, Fig.13 The voltage at DI11 in the dotted box 1 is 0V, the circuit in the dotted box 1 is a closed loop, and the photoelectric coupler performs electrical-optical-electrical signal conversion. In this way, the circuit in the dotted box 2 is also a closed loop, and DIGI-IN11 in the dotted box 2 outputs a signal to the control component 700. Fig.13 The dotted frame 1 can stabilize the voltage and filter the circuit.

[0093] When the charging gun 500 is not inserted into the gun socket 200, Fig.13 The voltage at DI11 in the dotted box 1 is 24V, the circuit in the dotted box 1 is a non-closed loop, and the photoelectric coupler cannot perform electrical-optical-electrical signal conversion. In this way, the circuit in the dotted box 2 is also a non-closed loop, and DIGI-IN11 in the dotted box 2 cannot output signals to the control component 700.

[0094] As a feasible implementation manner, the gun seat light emitting member 800, the optical sensor 202 and the gun return detection member 201 are all arranged on the gun insertion seat 200, and the gun seat light emitting member 800 and the optical sensor 202 are arranged at intervals.

[0095] For example, by setting the gun seat light emitting member 800 on the gun plug seat 200, when the gun seat light emitting member 800 emits light, the light first illuminates the gun plug seat 200, so as to effectively illuminate the location of the charging gun 500 and the user's field of vision, which is conducive to the user removing the charging gun 500.

[0096] By arranging the light sensor 202 and the gun holder light emitting member 800 at intervals, the interference of the light emitted by the gun holder light emitting member 800 on the light sensor 202 is avoided during the light emission process of the gun holder light emitting member 800, thereby improving the accuracy of the light sensor 202 in detecting the brightness of the ambient light. By arranging the gun return detection member 201 on the gun plug seat 200, when the charging gun 500 is inserted into the gun plug seat 200, the gun return detection member 201 detects the state of the charging gun 500 in real time and transmits information to the control member 700, so that the control member 700 controls the functions of the remaining components according to the state signal of the charging gun 500.

[0097] As a feasible implementation method, refer to Figure 3 and Figure 6 As shown, the charging pile further includes a gun head light emitting component 900 , which is disposed on the charging gun 500 , and the gun head light emitting component 900 is electrically connected to the control component 700 .

[0098] When the gun return detection component 201 detects that the charging gun 500 is separated from the gun socket 200 and the light sensor 202 detects that the ambient light brightness is less than the preset brightness value, the control component 700 is configured to control the gun head light emitting component 900 to emit light.

[0099] For example, the gun head light-emitting element 900 is arranged on the charging gun 500. When the charging gun 500 is separated from the gun socket 200, the gun return detection element 201 transmits the information that the charging gun 500 is separated from the gun socket 200 to the control element 700; the light sensor 202 transmits the ambient light brightness to the control element 700. When the ambient light brightness is less than the preset brightness value, the control element 700 controls the gun head light-emitting element 900 to light up according to the information obtained from the gun return detection element 201 and the light sensor 202.

[0100] By setting the gun head light-emitting element 900 on the charging gun 500, when the user holds the charging gun 500 and moves, the gun head light-emitting element 900 always illuminates the road ahead of the user and illuminates the direction of the user's advance, which is helpful for the user to match the charging gun 500 with the charging port of the vehicle, avoids friction between the charging gun 500 and the charging port of the vehicle, and avoids the charging gun 500 from scratching the vehicle.

[0101] Reference Fig.14 As shown, Fig.14 It is the Digital Output (DO) detection circuit of the gun mount light emitting element. When the control element 700 sends a light signal to the gun mount light emitting element 800, Fig.14 The voltage at CTRL-S2 in the dotted frame 1 is 0V, the circuit in the dotted frame 1 is a closed loop, and current flows through the inductor in the dotted frame 1. Under the action of electromagnetic induction, the switch in the dotted frame 2 is closed, the circuit in the dotted frame 2 is a closed loop, and the gun mount light emitting element 800 in the dotted frame 2 lights up. Fig.14 The dotted frame 1 can stabilize the voltage and filter the circuit.

[0102] When the control unit 700 does not send out a signal for the gun mount light emitting unit 800 to emit light, Fig.14 The voltage at CTRL-S2 in the dotted box 1 is 12V, the circuit in the dotted box 1 is a non-closed loop, no current flows through the inductor in the dotted box 1, the switch in the dotted box 2 is in the open state, the circuit in the dotted box 2 is a non-closed loop, and the gun mount light emitting part 800 in the dotted box 2 cannot light up.

[0103] As a feasible implementation mode, the charging pile further includes a charging detection component 1000, which is electrically connected to the control component 700, and the charging detection component 1000 is used to detect the charging status of the charging gun 500 and the charging port of the vehicle.

[0104] When the gun return detection component 201 detects that the charging gun 500 is detached from the gun socket 200, the charging detection component 1000 detects that the charging gun 500 is not connected to the charging port of the vehicle for charging, the distance detected by the distance detection component 300 is less than the preset distance value, and the light sensor 202 detects that the ambient light brightness is less than the preset brightness value, the control component 700 is configured to control the gun socket light-emitting component 800 to emit light.

[0105] When the charging detection component 1000 detects that the charging gun 500 is connected to the charging port of the vehicle for charging, the control component 700 is configured to control the light emitting component 900 at the gun head to emit light.

[0106] For example, refer to Figure 8 As shown, when the charging pile is in the night working state, after the charging pile completes charging the vehicle, when the user walks towards the charging pile body 100 holding the charging gun 500, at this time, the charging detection component 1000 transmits the uncharged information to the control component 700, and the gun return detection component 201 transmits the information that the charging gun 500 is not inserted into the gun socket 200 to the control component 700; the light sensor 202 detects the ambient light brightness in real time, and transmits the ambient light brightness to the control component 700 in real time; the distance detection component 300 detects the distance between the user and the charging pile body 100 in real time, and transmits the distance information to the control component 700. When the ambient light brightness is less than the preset brightness value and the distance between the user and the charging pile is less than the preset distance value, the control component 700 controls the gun socket light emitting component 800 to emit light, so that the user can insert the charging gun 500 into the gun socket 200 after use, thereby improving the docking efficiency of the charging gun 500 and the gun socket 200 and improving the user experience.

[0107] For example, the charging detection component 1000 may be a current detector.

[0108] As a feasible implementation manner, the gun head light emitting member 900 includes a first light emitting member 901 and a second light emitting member 902 , and the first light emitting member 901 and the second light emitting member 902 are arranged on the charging gun 500 at an interval.

[0109] When the gun return detection component 201 detects that the charging gun 500 is separated from the gun socket 200 and the light sensor 202 detects that the ambient light brightness is less than the preset brightness value, the control component 700 is configured to control the first light emitting component 901 to emit light.

[0110] When the charging detection element 1000 detects that the charging gun 500 is connected to the charging port of the vehicle for charging, the control element 700 is configured to control the second light emitting element 902 to emit light.

[0111] For example, refer to Figure 3 and Fig. 9As shown, the first light-emitting component 901 is arranged on the charging gun 500. When the charging gun 500 is separated from the gun socket 200 and the ambient light brightness is less than the preset brightness value, the control component 700 controls the first light-emitting component 901 to emit light according to the information that the ambient light brightness is lower than the preset brightness value transmitted by the light sensor 202 and the charging gun 500 is separated from the gun socket 201.

[0112] For example, refer to Fig.10 The second light-emitting element 902 is also provided on the charging gun 500. When the charging gun 500 is connected to the charging port of the vehicle for charging, the charging detection element 1000 transmits the charging information to the control element 700, and the control element 700 controls the second light-emitting element 902 to emit light.

[0113] By arranging the first light-emitting element 901 and the second light-emitting element 902 at intervals on the charging gun 500, when the user holds the charging gun 500 and moves, the light-emitting element 900 at the gun head always illuminates the road ahead of the user, which is helpful for the user to match the charging gun 500 with the charging port of the vehicle; when the charging gun 500 charges the vehicle, the second light-emitting element 902 prompts the user that the vehicle is charging.

[0114] By setting the gun mount light-emitting member 800, the first light-emitting member 901 and the second light-emitting member 902, the control member 700 controls the gun mount light-emitting member 800, the first light-emitting member 901 and the second light-emitting member 902 to emit light according to different information, thereby improving the light in the user's charging environment and irradiating in different areas, thereby improving the utilization rate of electric energy and improving the user's use effect.

[0115] For example, the first light emitting element 901 may be at least one of an incandescent lamp, a fluorescent lamp, a halogen tungsten lamp, a high pressure mercury lamp, and an LED (Light-Emitting Diode Light) lamp. The second light emitting element 902 may also be at least one of an incandescent lamp, a fluorescent lamp, a halogen tungsten lamp, a high pressure mercury lamp, and an LED (Light-Emitting Diode Light) lamp.

[0116] Reference Fig.11 As shown, Fig.11 This is the electrical contact definition diagram of the charging pile MCU. Fig.11 As shown in the dotted box 1, the J1 port is connected to the CAN communication of the external charging main control board, where the CAN communication is the controller area network; refer to Fig.11 As shown in the dashed box 2, the J2 port is used as a data signal output port, connecting the first light-emitting component 901, the second light-emitting component 902 and the gun base light-emitting component 800; Fig.11 As shown in the dotted box 3, the J3 port is connected to the external push rod motor 401; Fig.11As shown in the dotted box 4, the J4 port is connected to the gun detection component 201, the first limit trigger component 411 and the second limit trigger component 412 as an external input signal. Fig.11 As shown in the dashed box 5, the J5 port is connected to the light sensor 202; Fig.11 As shown in the dotted box 6 , the J6 port is connected to the distance detection component 300 .

[0117] As a feasible implementation, the distance detection element 300 includes at least one of a laser radar distance sensor, a laser rangefinder and an ultrasonic distance sensor.

[0118] For example, the distance detection component 300 can be any one of a lidar ranging sensor, a laser rangefinder and an ultrasonic distance sensor, the distance detection component 300 can also be any two of the lidar ranging sensor, the laser rangefinder and the ultrasonic distance sensor, or the distance detection component 300 can also be three of the lidar ranging sensor, the laser rangefinder and the ultrasonic distance sensor.

[0119] In some embodiments, at night, as shown in FIG7 , after the user parks the vehicle near the charging pile, the user gets off the vehicle and walks toward the charging pile body 100 . At this time, the light sensor 202 detects the ambient light brightness in real time, and transmits the ambient light brightness information to the control component 700 ; the distance detection component 300 detects the distance between the user and the charging pile body 100 in real time, and transmits the distance between the user and the charging pile to the control component 700 in real time; the gun return detection component 201 transmits the information of the charging gun 500 being inserted into the gun socket 200 to the control component. When the distance between the user and the charging pile body 100 is less than the preset distance value, for example, when the preset distance value is 0.5m, when the distance between the user and the charging pile body 100 is less than 0.5m, the control component 700 analyzes and obtains the information that the ambient light brightness is lower than the preset brightness value, the distance detection component 300 transmits that the distance between the user and the charging pile body 100 is less than the preset distance value, and the charging gun 500 is inserted into the gun socket 200, the control component 700 controls the gun socket light-emitting component 800 to light up, and the gun socket light-emitting component 800 illuminates the area near the gun socket 200.

[0120] When the user holds the charging gun 500 and moves away from the charging pile body 100, that is, the user holds the charging gun 500 and moves closer to the vehicle, at this time, the light sensor 202 detects the ambient light brightness in real time and transmits the ambient light brightness information to the control component 700; the distance detection component 300 detects the distance between the user and the charging pile body 100 in real time, and transmits the distance between the user and the charging pile to the control component 700 in real time; the return gun detection component 201 transmits the information that the charging gun 500 is separated from the gun socket 200 to the control component 700. When the control component 700 processes and obtains that the ambient light brightness is less than the preset brightness value and the charging gun 500 is separated from the gun socket 200, refer to Fig. 9As shown, the control member 700 is configured to control the first light-emitting member 901 to emit light, and the first light-emitting member 901 illuminates the direction in which the user is moving. In addition, the control member 700 controls the push rod motor 401 to start according to the distance between the user and the charging pile body 100, and the push rod motor 401 drives the push rod 402 to move in the vertical direction toward the bottom of the charging pile body 100, so that the charging gun line 600 is released, and the charging gun line 600 approaches the vehicle direction.

[0121] Reference Fig.10 As shown, when the user inserts the charging gun 500 into the charging port of the vehicle, the charging detection component 1000 transmits the charging information that the charging gun 500 is connected to the charging port of the vehicle to the control component 700, and then the control component 700 controls the second light-emitting component 902 to emit light. In this way, the second light-emitting component 902 is used to remind the user that the vehicle is charging, and the user does not need to get on the vehicle to confirm the charging status of the vehicle, thereby improving the user's comfort. In addition, during the process of the charging gun 500 charging the vehicle, the control component 700 controls the push rod motor 401 to turn off, and the push rod motor 401 no longer drives the push rod 402 to move, so as to avoid the shaking of the charging gun line 600 affecting the charging safety during the charging of the vehicle by the charging pile.

[0122] When the charging gun 500 is still inserted in the charging port, the charging detection component 1000 detects that the charging gun 500 and the charging port of the vehicle are not charged, and the charging detection component 1000 transmits the charging information that the charging gun 500 and the charging port of the vehicle are not connected to each other to the control component 700. The control component 700 is configured to control the second light-emitting component 902 to turn off. In this way, the user can directly confirm the charging status of the vehicle based on the lighting status of the second light-emitting component 902, thereby improving the performance of the charging pile.

[0123] When the user pulls out the charging gun 500 from the charging port, the user holds the charging gun 500 and moves it toward the charging pile body 100, that is, the user holds the charging gun 500 and moves away from the vehicle. At this time, the light sensor 202 detects the ambient light brightness in real time and transmits the ambient light brightness information to the control component 700; the distance detection component 300 detects the distance between the user and the charging pile body 100 in real time, and transmits the distance between the user and the charging pile to the control component 700 in real time; the return gun detection component 201 transmits the information that the charging gun 500 is separated from the gun socket 200 to the control component 700. When the ambient light brightness is less than the preset brightness value, the charging gun 500 is separated from the gun socket 200, and the control component 700 controls the first light-emitting component 901 to emit light. The first light-emitting component 901 illuminates the direction in which the user is moving. At this time, the distance detection component 300 detects the distance between the user and the charging pile body 100 in real time. The control component 700 controls the push rod motor 401 to start according to the distance between the user and the charging pile. The push rod motor 401 drives the push rod 402 to move along the vertical direction toward the top of the charging pile body 100, and then the charging gun line 600 is stored, and the charging gun line 600 approaches the charging pile body 100.

[0124] When the user inserts the charging gun 500 into the gun socket 200, the gun return detection member 201 detects that the charging gun 500 is inserted into the gun socket 200, and the control member 700 controls the first light-emitting member 901 to turn off, and the control member 700 controls the push rod motor 401 to turn off, and the push rod motor 401 no longer drives the push rod 402 to move.

[0125] When the user inserts the charging gun 500 into the gun socket 200, the gun return detection component 201 transmits the information that the charging gun 500 is inserted into the gun socket 200 to the control component 700, the light sensor 202 detects the ambient light brightness in real time, and the distance detection component 300 detects the distance between the user and the charging pile body 100 in real time. When the distance between the user and the charging pile body 100 is less than the preset distance value, the control component 700 determines that the ambient light brightness transmitted by the light sensor 202 is lower than the preset brightness value signal, the distance detection component 300 transmits the distance between the user and the charging pile body 100 is less than the preset distance value, and the charging gun 500 is inserted into the gun socket 200, and the control component 700 controls the gun socket light emitting component 800 to emit light.

[0126] In other embodiments, the control unit 700 has a timing function, and the control unit 700 can perform timing for the first time period and the second time period. During the first time period of timing by the control unit, if the distance detection unit 300 detects that the distance between the user and the charging pile body 100 is always less than the preset distance value, and the gun return detection unit 201 detects that the charging gun 500 is always inserted into the gun plug seat 200, the control unit 700 controls the gun seat light-emitting unit 800 to turn off, and then the control unit enters the second time period timing, and the distance detection unit 300 detects the distance between the user and the charging pile body 100 after the second time period, thereby controlling the on and off of the gun seat light-emitting unit 800. This can reasonably save electric energy.
