[0040] The upper end of the foundation 100 is provided with a mark to demarcate the parking area, so that the user can directly see and quickly park the car; the charging pile body 101 can charge the electric car; the user can input the car information, control the charging switch and payment functions through the operation panel; the charging cable and the charging head can both transmit electricity to charge the battery inside the electric car; a wire reel assembly is installed inside the storage slot 102, and the wire reel assembly can reel in the excess charging cable to prevent the charging cable from being dragged to the ground, thereby causing wear of the charging cable and affecting the charging effect of the electric car; the L-shaped support rod 103 can be installed with the vertical rod 104 and the adjustment assembly, and the L-shaped support rod 103 is fixed to the charging pile body 101, which can increase the stability of the L-shaped support rod 103 installed on the foundation 100 and prevent the front end of the L-shaped support rod 103 from tilting The vertical rod 104 cooperates with the baffle 105 to fall naturally, which can prevent the car from driving directly into the parking area; the adjustment component can drive the vertical rod 104, the baffle 105 and the camera 107 to rotate, which can not only allow the electric car to enter the parking range of the foundation 100, but also change the shooting direction of the camera 107; the camera 107 after changing the shooting direction cooperates with the monitoring head at the upper right corner of the front end of the charging pile body 101 to alternately capture the state between the charging line and the ground, so that the charging line is not damaged; the groove 106 can accommodate the installation of the camera 107, so that the camera 107 is in the middle position of the baffle 105, which is convenient for directly capturing the license plate of the car; the control module can process the image information captured by the camera 107 and the monitoring head, and control the opening or closing of the adjustment component and the winding component according to these data information.

[0041] The first servo motor 200, as a power source, can drive the threaded rod 202 to rotate; the installation groove 201 can not only facilitate the installation of the first servo motor 200 and the threaded rod 202, but also reduce the weight of the upper part of the L-shaped support rod 102, and prevent the L-shaped support rod 103 from tilting forward; the threaded rod 202 can drive the moving block 203 to move inside the installation groove 201, and also drive the connecting block 205 and the connecting rod 206 to move. Relying on the moving traction of the connecting rod 206, the vertical rod 104 can be rotated, so that the electric vehicle can enter and exit;

[0042] Among them, the rear end of the threaded rod 202 is fixedly connected to the output end of the first servo motor 200, and the front end of the threaded rod 202 is rotatably connected to the installation groove 201. This not only makes the installation of the threaded rod 202 more stable, but also does not affect the rotation of the threaded rod 202.

[0043] The front and rear sets of limiters limit the travel of the moving block 203 in the installation slot 201. When the moving block 203 contacts and presses any of the front and rear touch switches 208, the first servo motor 200 can be stopped, thereby protecting the adjustment component from damage.

[0044] When the moving block 203 is pressed and abutted against the touch switch 208 on the front side, the vertical rod 104 and the baffle 105 are in a naturally drooping state; when the moving block 203 is pressed and abutted against the touch switch 208 on the rear side, the vertical rod 104 and the baffle 105 are parallel to the upper part of the L-shaped support rod 103.

[0045] The take-up reel 300 can reel the charging cable into the storage slot 102; the two V-shaped brackets 301 make it convenient for the staff to install or replace and repair the take-up reel 300; the collector ring 302 can fix one end of the charging cable and wrap the other end around the take-up reel 300, so that electricity can be transmitted, and the charging switch can also be controlled through the operation panel; the transmission assembly can drive the rotation of the take-up reel 300 to reel the charging cable, and when the user pulls out the charging cable, the transmission assembly will not be damaged.

[0046] The protective groove 304 can install and protect the second servo motor 303; the second servo motor 303 provides power for the entire transmission assembly; the rotating rod 305 transmits the power of the second servo motor 303 to the ratchet 306, so that the ratchet 306 rotates; one end of the metal block 308 is inserted into the tooth groove of the ratchet 306, so the ratchet 306 can drive the metal block 308 to rotate, and because one end of the metal block 308 is rotatably connected to the limit plate 307, and the other end is inserted into the tooth groove of the ratchet 306; the control module energizes the electromagnet 309 to generate magnetic force, which can adsorb the metal block 308 and disengage the metal block 308 from the tooth groove of the ratchet 306; the spring piece 310 abuts against the upper surface of the metal block 308, so that the metal block 308 can be always inserted into the tooth groove of the ratchet 306, thereby allowing the transmission rod assembly to operate.

[0047] Initially: the vertical rod 104 and the baffle 105 are in a naturally hanging state, and the vertical rod 104 and the baffle 105 are perpendicular to the L-shaped support rod 103, blocking the vehicle from directly parking in the parking area on the foundation 100.

[0048] When the car reverses into the front of the parking area on the foundation 100, the camera 106 will capture the tendency of the car to enter the parking area and the license plate of the car. The image data captured by the camera 107 is transmitted to the control module, and the control module determines that

[0049] When the license plate is not green, the control module will not allow the car to pass, and the vertical rod 104 and the baffle 105 will prevent the car from parking.

[0050] When the license plate is green: the control module determines that it is an electric car. At this time, the control module will send a start command to the first servo motor 200, and the first servo motor 200 will start. The output shaft of the first servo motor 200 drives the threaded rod 202 to rotate, and the threaded rod 202 drives the moving block 203 to move backward along the installation groove 201, and the moving block 203 drives the connecting block 205 and the connecting rod 206 to move backward. Since the upper end of the vertical rod 104 is hinged to the lower end of the L-shaped support rod 103, and the connecting rod 206 is hinged to the lower side of the rear end of the vertical rod 104, the vertical rod 104, the baffle 105 and the camera 107 will be driven to rotate backward under the traction of the connecting rod 206 until the moving block 203 is pressed against the touch switch 208 on the rear side, and the first servo motor 200 will stop. At this time, the vertical rod 104, the baffle 105 and the camera 107 will be parallel to the upper part of the L-shaped support rod 103, so that the electric car can be parked inside the parking area on the foundation 100.

[0051] When charging an electric vehicle: the user first removes the charging head and connects it to the charging port of the electric vehicle, then enters the relevant information of the vehicle through the operation panel, and finally turns on the charging mode through the operation panel. During this process:

[0052] When the charging cable pulled out by the user is separated from the ground: the charging cable is in a suspended state.

[0053] When the charging cable pulled out by the user touches the ground: the charging cable is in a mopping state. At this time, the images taken by the camera 107 in coordination with the monitoring head can be transmitted to the control module, and the control module sends a start command to the second servo motor 303. The output shaft of the second servo motor 303 drives the rotating rod 305 to rotate, the rotating rod 305 drives the ratchet 306 to rotate, the ratchet 306 drives the metal block 308 to rotate, the metal block 308 drives the limit plate 307 to rotate, and the limit plate 307 drives the take-up reel 300 to rotate, so that the mopping charging cable can be rolled up into the storage slot 102.

[0054] Among them, the metal block 308 is initially adsorbed by the electromagnet 309, so that when the charging cable is pulled out, the take-up drum 300 will rotate counterclockwise. Since there is no contact between the metal block 308 and the ratchet 306, it will not affect the second servo motor 303. When the camera 107 and the monitoring head detect that the charging cable is in contact with the ground, the control module will disconnect the power of the electromagnet 309. Since the spring piece 310 abuts against the upper surface of the metal block 308, after the electromagnet 309 loses its magnetism, the spring piece 310 will push the metal block 308 to be stuck in the tooth groove of the ratchet 306. In this way, when the ratchet 306 rotates clockwise, it will also push the metal block 308, the limit plate 307 and the take-up drum 300 to rotate, thereby realizing the winding function of the charging cable.

[0055] When the electric car is finished charging: the user needs to pay through the operation panel to terminate the settlement of the charging amount.

[0056] When the electric car leaves the parking area; after the camera 107 captures the electric car leaving, the control module will start the first servo motor 200, and the first servo motor 200 will drive the threaded rod 202 to rotate in the opposite direction, and push the moving block 203 to move forward until the moving block 203 is pressed against the touch switch 208 on the front side, at which time the first servo motor 200 will stop running, and the vertical rod 104 and the baffle 105 will be perpendicular to the L-shaped support rod 103, and once again block non-electric vehicles from docking.

[0057] In this embodiment, by setting up an inclined camera 107, not only can the car be identified when entering the parking area, and electric vehicles can be screened out to prevent other types of cars from occupying the parking area and affecting the charging of the electric vehicle, but also when charging the electric vehicle, it can be monitored in real time whether the charging cable is dragged on the ground. By relying on the mutual cooperation of the take-up assembly and the transmission assembly, the charging cable can be kept away from the ground to prevent the charging cable from being worn and affecting the transmission of electricity.

[0058] Embodiment 2:

[0059] like Figure 2-Figure 9 As shown, based on the first embodiment, other components of a charging monitoring system for an electric vehicle are further described. A through groove 400 is provided on the upper surface of the connecting rod 206, and a plurality of interception blocks 401 are evenly distributed between the left and right inner walls of the through groove 400.

[0060] A U-shaped ring 402 is provided in the middle of the right end of the charging pile body 101 , a notch is provided on the front side of the U-shaped ring 402 , the charging line is arranged inside the U-shaped ring 402 , and a fixing block 403 matching the ring opening of the U-shaped ring 402 is wrapped around the outside of the charging line.

[0061] In this embodiment, the through slot 400 can accommodate the lines for telecommunication connection between the camera 107 and the control module, and each interception block 401 can prevent the lines from being exposed from the through slot 400, thereby avoiding damage to the lines and affecting the data transmission captured by the camera 107.

[0062] The U-shaped ring 402 can be used to conveniently place the charging cable and the charging head, and the fixing block 403 can be inserted into the notch of the U-shaped ring 402 to keep the charging head away from the ground to prevent damage to the charging head;

[0063] The U-shaped ring 402 is located in the middle of the charging pile body 101, which not only prevents the charging cable from being dragged on the ground when the user pulls out the charging cable, but also makes it easier for the user to take it.

[0064] The user can insert the charging cable into the notch of the U-shaped ring 402 through the notch of the U-shaped ring 402, which is convenient for the user to use.

[0065] Embodiment three:

[0066] like Figure 1-9 As shown, the specific operation steps based on the above embodiment are:

[0067] S1: When the car reverses into the range of the foundation 100, the camera 107 can aim at the license plate of the car to take a picture, and the graphic information taken by the camera 107 will be transmitted to the control module, and the control module will judge the license plate of the car. When the license plate of the car is green, the control module determines that the car is an electric car, and the control module will send a command to the first servo motor 200; start the first servo motor 200, the output shaft of the first servo motor 200 drives the threaded rod 202 to rotate, and the threaded rod 202 drives the moving block 203 in the installation groove 201 The first servo motor 200 moves backward, and the moving block 203 drives the connecting block 205 and the connecting rod 206 to move backward. Since the lower end of the connecting rod 206 is hinged to the vertical rod 104, and the vertical rod 104 is hinged to the L-shaped support rod 103, the connecting rod 206 will drive the vertical rod 104 and the baffle 105 to rotate backward until the moving block 203 abuts against and presses the touch switch 208 to stop the first servo motor 200. At this time, the vertical rod 104 and the baffle 105 will be parallel to the upper part of the L-shaped support rod 103, so that the electric car can drive into the middle of the foundation 100.

[0068] Among them, the front end of the L-shaped support rod 103 is located above the front half of the parking area of ​​the foundation 100, which can avoid the camera 107 from making misdetection when the car passes through the entrance of the foundation 100. Only when the car enters the front half of the foundation 100 can the camera 107 monitor the trend of the car wanting to enter the parking area and perform detection.

[0069] S2: After the user gets off the vehicle, he first removes the charging head and connects it to the charging port of the electric vehicle, then inputs the information of the electric vehicle through the operation panel, and then the electric vehicle can be charged; while pulling the charging line, the camera 107 will change the shooting angle under the rotation of the vertical rod 104 and the baffle 105, so that the shooting direction of the camera 107 is facing downward, so that the camera 107 can monitor the status between the charging line and the ground in real time in cooperation with the monitoring head;

[0070] When the charging line contacts the ground, the control module determines that this is an abnormal state. At this time, the control module will send a command to the second servo motor 303. At the same time, the power supply to the electromagnet 309 will be disconnected. After the second servo motor 303 is started, the output shaft of the second servo motor 303 drives the rotating rod 305 to rotate, and the rotating rod 305 drives the ratchet 306 to rotate. Since the electromagnet 309 no longer absorbs the metal block 308, the spring 310 will clamp the metal block 308 into the ratchet 306. , so that the ratchet 306 can drive the metal block 308, the limit plate 307 and the take-up reel 300 to rotate clockwise, thereby winding up the charging cable. After the camera 107 and the monitoring head detect that the charging cable is off the ground, the control module will stop the second servo motor 303 and let the electromagnet 309 absorb the metal block 308 again, so that the metal block 308 is separated from the tooth groove of the ratchet 306, thereby preventing the user from pulling out the charging cable and causing damage to the charging cable.

[0071] S3: When the electric vehicle is fully charged, the user removes the charging head and pays the charging fee of the electric vehicle on the operation panel through WeChat or other supported methods on the mobile phone. Only then will the charging pile body 101 disconnect the charging billing of the electric vehicle.

[0072] S4: When the electric car leaves, the camera 107 detects that there is no vehicle inside the foundation 100 area, and the control module will issue a command to the first servo motor 200 to rotate the threaded rod 202 and push the moving block 203 to move forward. The moving block 203 pushes the vertical rod 104 to rotate forward until the front end of the moving block 203 abuts against the touch switch 208 on the front side, and the vertical rod 104 will be perpendicular to the L-shaped support rod 103, thereby realizing a new round of interception of the car.
