[0055] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0057] The present invention provides an intelligent charging system for an autonomous driving vehicle.

[0058] Please refer to Figures 1 to 3 In an embodiment of the present invention, a smart charging system for an autonomous driving vehicle includes:

[0059] A power access module, a central processing module, a human-computer interaction module, two charging gun modules, and an AI detection module. The power access module is signal-connected to the central processing module, the human-computer interaction module is signal-connected to the central processing module, and both charging gun modules are signal-connected to the central processing module. The AI detection module is signal-connected to the power access module, the central processing module, the human-computer interaction module, and the two charging gun modules, respectively.

[0060] The AI detection module includes an AI learning unit, a current detection unit, a temperature detection unit, an abnormality alarm unit, and an abnormality decision unit. The AI learning unit is used to learn the safe fluctuation range of the current and temperature of the charging gun module when charging different types of vehicles. The AI learning unit also performs intelligent analysis based on the data detected by the current detection unit and the temperature detection unit, and sends decision information to the abnormality alarm unit and the abnormality decision unit based on the analysis results, so as to realize automatic alarm and automatic decision-making when the charging gun module data is abnormal.

[0061] After the detection data of the charging gun module is abnormal and an alarm is automatically issued, if the maintenance personnel cancel the alarm information but do not make a corresponding decision, the AI learning unit automatically updates the safe fluctuation range of current and temperature of the vehicle type based on the current vehicle type and detection data.

[0062] In this embodiment, the decision information may be to send only an alarm message without autonomously shutting off the power and waiting for maintenance personnel to perform maintenance operations;

[0063] The decision information may also be an alarm message sent, which automatically cuts off the power and waits for maintenance operations by maintenance personnel.

[0064] In this embodiment, the power access module is used to connect the input power to the system, and after processing the input power, distribute it to the central processing module, the human-computer interaction module, the two charging gun modules and the AI detection module to provide support for the system's operating power supply and the power supply of the charging gun module.

[0065] In this embodiment, the central processing module is used to process data, and the AI detection module is integrated into the central processing module to realize intelligent identification, analysis, updating and decision-making processing of data; the AI detection module is used in a network to facilitate online transmission of data and provide technical support for online management and monitoring of smart charging.

[0066] The human-computer interaction module is used for manual selection operations by users / maintenance personnel, facilitating manual selection of charging time and fee payment.

[0067] After the detection data of the charging gun module is abnormal and the alarm time reaches the preset time range, if there is no maintenance personnel to cancel the maintenance, the AI learning unit automatically disconnects the power supply of the charging gun module and continues to detect the abnormal data area after power failure; if the abnormal data returns to normal, the AI learning unit continues to supply power to the charging gun module; if the abnormal data does not return to normal, the AI learning unit issues an emergency alarm and disconnects all charging gun modules of the current device.

[0068] The AI detection module performs real-time detection of the temperature and current during vehicle charging. The temperature and current data are analyzed based on the recorded vehicle type. When the temperature or current data exceeds the safe range allowed by the vehicle type, the AI detection module automatically issues an alarm. When the alarm time is within the preset time range and the maintenance personnel cancel the alarm without performing a power-off operation, the AI detection module automatically updates the safe range of the temperature or current data for the vehicle type, realizing automatic update and maintenance of the intelligent charging detection data of autonomous driving vehicles, reducing downtime maintenance time and manual maintenance costs, and improving the autonomous learning ability of the charging system.

[0069] Example: When vehicle A is DC charging, the current range is 50A~500A and the temperature range is ≤50℃:

[0070] After vehicle A is connected to the charging gun module, it enters the charging state;

[0071] When the current detection unit detects that the constant current of the charging gun module is 480A and the temperature detection unit detects that the temperature of the charging gun module is 55°C, the abnormal alarm unit sends an alarm message to the maintenance personnel, indicating that the charging temperature is abnormal, and records the duration of the alarm message sending;

[0072] If maintenance personnel arrive at the scene within five minutes and manually disable the alarm without stopping charging, the AI learning unit automatically updates the temperature range for DC charging of the vehicle type to ≤55°C.

[0073] If the maintenance personnel have not arrived at the scene after five minutes, the abnormal decision unit will cut off the power to the charging gun module and continue to monitor the temperature changes after the power outage; when the temperature returns to normal within 2 minutes after the power outage, the abnormal decision unit will turn on the power to the charging gun module and continue to charge the autonomous driving vehicle; when the temperature does not return to normal within 2 minutes after the power outage, the power is maintained off, and the abnormal alarm unit sends an emergency alarm message to notify the maintenance personnel to deal with it urgently to avoid charging accidents.

[0074] In this embodiment, the AI learning unit also records and analyzes the number of temperature abnormality alarms of the charging gun module. When the charging gun module is charging continuously and more than three vehicle temperature abnormality alarms are issued, the AI learning unit will feedback the charging abnormality of the charging gun module to the maintenance personnel and automatically stop the use of the charging gun module until the maintenance personnel checks and authorizes continued use, and then allow the charging gun module to continue to be used; or after the maintenance personnel replaces the charging gun module, the charging gun module at this workstation is allowed to be powered on.

[0075] Please refer again Figure 2The human-computer interaction module includes a touch display unit, a charging selection unit, a charging payment unit, a vehicle identification unit, a wireless communication unit and an ETC identification unit. The touch display unit is used to display data and select touch operations; the charging selection unit is used to provide a selection of charging time; the charging payment unit is used to provide a selection of payment mode; the vehicle identification unit is used to scan and identify the vehicle type and license plate; the wireless communication unit is used to communicate with the terminal device of the maintenance personnel; the ETC identification unit provides the charging vehicle with ETC identification and automatic payment functions.

[0076] It is convenient to provide users with a variety of charging payment methods. When the vehicle has the ETC payment function, it provides support for intelligent identification and intelligent unlocking of the charging gun module, which facilitates the automatic unlocking and use of the charging gun module after ETC identification; after unlocking, the charging gun module can be inserted into the charging port of the autonomous driving vehicle. After insertion, the charging gun module starts to automatically supply power until charging is completed; after charging is completed, the ETC identification unit automatically deducts the fee from the ETC.

[0077] The touch display unit is used to display system prompt information, charging vehicle information, charging selection and payment information, and current and temperature information monitored in real time during the charging process.

[0078] The charging selection unit selects the charging time through the touch display unit, and the charging payment unit automatically generates the charging order amount according to the charging selection unit, and does not provide the user with different charging payment methods; when the charging payment is completed, the charging gun module is automatically unlocked, and after the charging gun module is inserted into the autonomous driving vehicle, the charging gun module starts to supply power and start; the vehicle identification unit is used to visually detect and identify the vehicle type and license plate information, which facilitates the registration and identification of the charging vehicle. According to the registered vehicle type, the preset charging current and charging temperature safety range are selected to provide support for current and temperature abnormality detection.

[0079] The wireless communication unit is used for online communication management of maintenance personnel, which facilitates sending alarm information to the maintenance personnel's management equipment, and the management equipment can be a computer, monitoring equipment and mobile phone.

[0080] The ETC identification unit is used to identify the vehicle ETC, and can automatically deduct fees through the vehicle ETC according to the fees generated by the current vehicle charging, facilitating smart charging and payment, and simplifying the payment and charging process of ETC vehicles.

[0081] Furthermore, after the vehicle identification unit identifies the license plate information of the autonomous vehicle, the ETC identification unit matches the license plate information with the identified vehicle ETC information and extracts the remaining amount in the vehicle's ETC. The AI learning unit analyzes whether the remaining amount meets the requirement of fully charging based on the vehicle type and the remaining power.

[0082] If the conditions are met, the charging gun module is automatically unlocked. After the charging gun module is inserted into the autonomous vehicle, charging is automatically performed until the autonomous vehicle is fully charged / the charging gun module is unplugged, and ETC payment is automatically performed without human-computer interaction.

[0083] If the requirements are not met, ETC automatic payment cannot be performed, and the charging time and payment method must be manually selected with the human-computer interaction module; after the payment is completed, the charging gun module is unlocked, and after the charging gun module is inserted into the vehicle, charging is automatically performed. After charging is completed, the unused amount will be refunded.

[0084] The working principle of the intelligent charging system for autonomous driving vehicles provided in this embodiment is as follows:

[0085] A1: The autonomous driving vehicle is identified through the human-computer interaction module. When it is identified that the vehicle has ETC automatic payment, the charging gun module is automatically unlocked;

[0086] A2: When the user inserts the charging gun module into the charging port of the autonomous driving vehicle, the charging gun module starts to supply power;

[0087] A3: During the autonomous driving charging process, the AI detection module performs real-time detection and analysis of the temperature and current of the charging gun module;

[0088] A4, automatically analyzes and decides whether to alarm and power off based on the current and temperature of the charging gun module to maintain safe operation of the system.

[0089] The present invention also provides an intelligent charging device for an autonomous driving vehicle.

[0090] Please refer to Figure 4 、 Figure 5 and Figure 6 , an intelligent charging device for an autonomous driving vehicle, integrated with the intelligent charging system for the autonomous driving vehicle, comprising:

[0091] A chassis 1 is provided with an air inlet window 10 and an air outlet window 11, wherein the air inlet window 10 is provided on the back side of the chassis 1, and the air outlet window 11 is provided on the side of the chassis 1;

[0092] The switch mechanism 4 includes a first telescopic member 41, a connecting frame 42, and a first switch plate 43. The two ends of the first telescopic member 41 are fixedly connected to the connecting frame 42 and the chassis 1. The top of the first switch plate 43 is fixedly connected to the bottom of the connecting frame 42. The first switch plate 43 is slidably mounted on the chassis 1 and is located within the opening range of the air outlet window 11.

[0093] A second switch plate 5, the top of which is fixedly connected to the bottom of the connecting frame 42, and the second switch plate 5 is slidably mounted on the chassis 1 and located within the opening range of the air inlet window 10;

[0094] A ventilation and cooling device 6, wherein the ventilation and cooling device 6 is installed in the chassis 1, and an output end of the ventilation and cooling device 6 faces the range of the air outlet window 11;

[0095] The first telescopic member 41 is used to drive the connecting frame 42 to rise and fall. When the connecting frame 42 is in a downward state, the first switch plate 43 and the air outlet window 11 are closed, and the second switch plate 5 and the air inlet window 10 are closed; when the connecting frame 42 is in an upward state, the first switch plate 43 and the air outlet window 11 are opened, and the second switch plate 5 and the air inlet window 10 are opened.

[0096] In this embodiment, the connecting frame 42 includes two usage states:

[0097] Combine Figure 6 (b) and Figure 7 In (b), in the downward pressure state, the air outlet of the first switch plate 43 is staggered with the air outlet of the air outlet window 11, and the air outlet of the second switch plate 5 is staggered with the air outlet of the air inlet window 10. This facilitates closing the air outlet window 11 and the air inlet window 10 when the device is not charging, thereby reducing the ingress of wind and sand into the interior of the chassis 1 and extending the service life of the device outdoors;

[0098] Combine Figure 8 (b) and Figure 9 In (b), in the lifted state, the air outlet of the first switch plate 43 is horizontally connected to the air outlet of the air outlet window 11, and the air outlet of the second switch plate 5 is horizontally connected to the air outlet of the air inlet window 10, so that when the device is charging, the air outlet window 11 and the air inlet window 10 are opened synchronously, which is convenient for ventilation and cooling when the device is charging.

[0099] In this embodiment, the ventilation and cooling device 6 is used to provide support for ventilation and cooling inside the chassis 1 after the first switch board 43 and the second switch board 5 are opened.

[0100] When the chassis 1 does not need to be charged, the first telescopic member 41 is used to drive the connecting frame 42 to move downward, so that the connecting frame 42 is adjusted to a downward-pressed state, maintaining the first switch plate 43 and the second switch plate 5 closed, and reducing the entry of external dust into the interior of the chassis 1; when it is necessary to provide charging support for the autonomous driving vehicle, the first telescopic member 41 is used to drive the connecting frame 42 to move upward, so that the connecting frame 42 is adjusted to an upward-lifting state, maintaining the first switch plate 43 and the second switch plate 5 open, so as to facilitate ventilation and cooling of the chassis 1 during use.

[0101] In this embodiment, the first telescopic member 41 may be an electric telescopic rod, and the first telescopic member 41 is used to directly drive the connecting frame 42 to rise and fall, so as to facilitate the independent driving of the first switch plate 43 and the second switch plate 5 .

[0102] Please refer to Figure 4 、 Figure 5 and Figure 6 , the chassis 1 is also provided with a power supply module 12 and a plug-in module 13, and the power supply module 12 is distributed above the plug-in module 13;

[0105] The locking mechanism 3 includes a motor 31 and a cam 32. The motor 31 is fixed in the chassis 1. The cam 32 is fixed on the drive shaft of the motor 31. The bottom of the connecting frame 42 abuts against the top of the cam 32.

[0106] When the cam 32 is in a locked state, the cam 32 is inserted into the range of the locking groove 231 and locks the charging gun head 23; when the cam 32 is in an unlocked state, the cam 32 is out of the range of the locking groove 231 and the charging gun head 23 is unlocked.

[0107] In this embodiment, the cam 32 includes two usage states:

[0108] like Figure 6 As shown in (a), in the locked state, the surface of the cam 32 is inserted into the range of the locking groove 231, and the charging gun head 23 is locked and cannot be pulled out;

[0109] like Figure 8 As shown in (a), in the unlocked state, the surface of the cam 32 is out of the range of the locking groove 231, and the charging gun head 23 can be pulled out after being unlocked.

[0110] When the charging gun head 23 needs to be used, the motor 31 is started, and the motor 31 drives the cam 32 , and the cam 32 rotates counterclockwise, and the cam 32 disengages from the locking groove 231 , so that the charging gun head 23 is unlocked.

[0111] Please refer to Figure 11 (a) and Figure 12 In (a), the power supply connector 21 includes a connector 211, a conductive ring 210, a protective tube 212 and a third telescopic member 213. One end of the connector 211 is connected to the cable 22. The conductive ring 210 is integrally mounted on the connector 211. The protective tube 212 is slidably mounted on the connector 211. The third telescopic member 213 elastically connects the connector 211 and the protective tube 212. When the protective tube 212 is opened, the conductive ring 210 is exposed. When the protective tube 212 is closed, the conductive ring 210 is retracted within the protective range of the protective tube 212.

[0112] In this embodiment, the protective tube 212 includes two usage modes:

[0113] In the open mode, the protective tube 212 is retracted and the conductive ring 210 is exposed, which facilitates the docking or separation of the conductive portion of the conductive docking device 73 and the conductive ring 210;

[0114] In the closed state, the protective tube 212 is extended and the conductive ring 210 is retracted within the protective tube 212 . The protective tube 212 shields and protects the conductive ring 210 , facilitating the protection of the conductive ring 210 after the connector 211 is separated from the power supply module 12 .

[0115] By providing the protective tube 212 on the connector 211, the protective tube 212 can conveniently shield and protect the conductive ring 210 when the connector 211 is not in use, so that the detachable charging gun mechanism 2 has a safety protection function before installation; when the connector 211 is in use, the protective tube 212 can be opened, and the conductive ring 210 is exposed, providing support for the docking of the conductive docking device 73 with the conductive ring 210.

[0116] In an optional implementation of this embodiment, the third telescopic member 213 may be an electric telescopic rod for directly driving the protective tube 212 to telescope relative to the connecting head 211 , thereby facilitating independent driving and adjustment of the protective tube 212 .

[0117] In another optional implementation of this embodiment, please refer to Figure 6 and Figure 11 In (a), the third telescopic member 213 is a spring telescopic tube member, and the third telescopic member 213 elastically connects the connector 211 and the protective tube 212;

[0118] The intelligent charging device for the autonomous vehicle further includes a quick-connect locking mechanism 7, which includes a second telescopic member 71, a synchronization frame 72, and a conductive docking device 73. The second telescopic member 71 is fixedly connected to the chassis 1 and the synchronization frame 72. One side of the conductive docking device 73 is fixedly mounted on the bottom of the synchronization frame 72, and the other side of the conductive docking device 73 passes through the power supply module 12 and abuts against the conductive ring 210 on the surface of the power supply connector 21.

[0119] When the connector 211 is inserted into the power supply module 12 , the protective tube 212 abuts against the conductive docking device 73 to maintain the protective tube 212 open.

[0120] In this embodiment, when the conductive docking device 73 is in contact with the conductive ring 210, the conductive docking device 73 can also provide a locking limit for the connector 211 after it is inserted. During this period, the connector 211 cannot be pulled out from the power supply module 12; when the conductive docking device 73 is separated from the conductive ring 210, the conductive docking device 73 is separated from the withdrawal range of the connector 211, providing support for the rapid removal of the connector 211 from the power supply module 12.

[0121] In this embodiment, the conductive docking device 73 includes two usage modes:

[0122] like Figure 11 As shown in (a), in the docking state, the conductive end of the conductive docking device 73 abuts against the conductive ring 210, the conductive docking device 73 abuts against the protective tube 212, the protective tube 212 is in the open state, and the conductive docking device 73 and the connector 211 are locked and limited, which facilitates the locking of the connector 211 after installation;

[0123] like Figure 11 As shown in (b), in the separated state, the conductive end of the conductive docking device 73 is separated from the conductive ring 210, the conductive docking device 73 is in contact with the protective tube 212, the protective tube 212 is in the open state, and the conductive docking device 73 is unlocked from the connector 211, facilitating the quick release of the connector 211.

[0124] The protective tube 212 is elastically mounted on the connector 211 through the third telescopic member 213. When the connector 211 is inserted into the power supply module 12, the protective tube 212 will preferentially abut against the edge of the conductive docking device 73, so that when the connector 211 is fully inserted into the power supply module 12, the protective tube 212 automatically opens relative to the connector 211, so that the conductive ring 210 is automatically exposed, facilitating the automatic opening of the conductive ring 210.

[0125] Please refer to Figure 11 (a) and Figure 12 In (a), the conductive docking device 73 includes a locking slide 731, a buffer slide 732, an elastic member 733 and a conductive member 734. One side of the locking slide 731 is fixedly connected to the synchronization frame 72, and the other side of the locking slide 731 passes through the power supply module 12 and abuts against one end of the protective tube 212. The buffer slide 732 is slidably installed in the locking slide 731. The two ends of the elastic member 733 elastically connect the buffer slide 732 and the locking slide 731. One end of the conductive member 734 is fixed on the buffer slide 732, and the other end of the conductive member 734 passes through the locking slide 731 and abuts against the conductive ring 210.

[0126] In this embodiment, there are at least nine conductive members 734 , which are arranged in a one-to-one correspondence with the conductive rings 210 , and two adjacent conductive members 734 are arranged at intervals, and two adjacent conductive rings 210 are arranged at intervals to adapt to the number of lines of the charging gun.

[0127] The elastic member 733 elastically connects the buffer slide 732 and the locking slide 731, providing elastic buffering support for the buffer slide 732 and the conductive member 734 thereon; the input end of the conductive member 734 is electrically connected to the power supply circuit of the system; so that when the conductive member 734 abuts against the conductive ring 210, it can provide power supply support when the charging gun head 23 is started and used.

[0128] The conductive part 734 and the conductive ring 210 are connected in an elastic abutment manner, which on the one hand prevents rigid collision damage when the conductive part 734 and the conductive ring 210 abut against each other; on the other hand, it prevents the connection between the fixed structure from being loose or separated after repeated use, thereby ensuring the stability of the equipment during long-term operation.

[0129] In this embodiment, the second telescopic member 71 is an electric telescopic cylinder, which provides a power source for the movement and adjustment of the synchronization frame 72, so as to facilitate the synchronous movement and adjustment of the synchronization frame 72 and the conductive docking device 73, thereby providing a separate adjustment power for the use mode switching of the conductive docking device 73.

[0130] Furthermore, a high-definition camera is integrated in the chassis 1, and the high-definition camera visually recognizes the vehicle outside the chassis through a transparent plate.

[0131] By installing a high-definition camera, it is easy to identify the vehicle type and license plate information, so as to facilitate visual recognition of the vehicle.

[0132] The working principle of the intelligent charging system for autonomous driving vehicles provided in this embodiment is as follows:

[0133] like Figure 6 (a) in Figure 7 (a) in Figure 11 (a) and Figure 12 As shown in (a), it may be defined that in the initial state, the power connector 21 is in a non-charging state, the cam 32 is inserted into the range of the locking groove 231, the charging gun head 23 is locked and installed on the plug-in module 13, the first switch plate 43 and the second switch plate 5 are closed, the locking slide 731 is inserted into the power module 12 and abuts against the connector 211 to limit its position, and the conductive member 734 abuts against the conductive ring 210 and is electrically connected;

[0134] See also Figure 6 (a) and Figure 8 In (a), when the charging gun head 23 needs to be used for power supply, the motor 31 is started, and the motor 31 drives the cam 32 to rotate counterclockwise. When the cam 32 rotates counterclockwise, it gradually moves out of the range of the locking groove 231, thereby automatically unlocking the charging gun head 23. After the charging gun head 23 is unlocked, it is convenient to insert the charging gun head 23 into the interface of the autonomous driving vehicle to power the autonomous driving vehicle;

[0135] Please refer to Figure 8 and Figure 9 After the charging gun head 23 is unlocked, the first telescopic member 41 is activated, and the first telescopic member 41 drives the connecting frame 42 to move upward, so that the connecting frame 42 drives the first switch plate 43 and the second switch plate 5 to move upward synchronously, so that the first switch plate 43 and the second switch plate 5 are opened synchronously, so that the first switch plate 43 and the second switch plate 5 can be automatically opened when the charging gun head 23 is used;

[0136] Please combine Figure 8 (a) and Figure 10 When the charging gun head 23 needs to be quickly replaced, the second telescopic member 71 is activated while the charging gun head 23 is unlocked. The second telescopic member 71 drives the synchronization frame 72 to move leftward. The synchronization frame 72 moves leftward and drives the locking slide 731 to move. When the locking slide 731 moves, it drives the elastic member 733, the buffer slide 732 and the conductive member 734 to move synchronously, so that the conductive member 734 is separated from the conductive ring 210.

[0137] When the conductive member 734 is separated from the conductive ring 210 , the surface of the locking slide 731 is out of the plugging and unplugging range of the connector 211 , thereby facilitating the quick removal of the connector 211 .

[0138] Ultimately, modular connection and disassembly of the charging gun mechanism 2 is facilitated, so as to facilitate rapid maintenance and replacement of the charging gun mechanism 2 .

[0139] When the connector 211 is pulled out from the power supply module 12 , the third telescopic member 213 adaptively drives the protective tube 212 to close, so as to fold and protect the conductive ring 210 when not in use, thereby extending the service life of the modular charging gun mechanism 2 .

All equivalent structural transformations made by using the contents of the present invention description and drawings under the concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
