[0034] The surface of the base 1 is provided with a blocking assembly 4, which includes a license plate recognition camera 41, a bottom plate 42, a positioning block 43, a blocking plate 44, a hinge rod 45, a threaded plate 46, a screw rod 47, a motor 48 and a slide rail 49;

[0035] A license plate recognition camera 41 is fixed to the front surface of the charging pile body 2, and a bottom plate 42 is symmetrically fixed on both sides of the surface of the base 1.

[0036] The present invention also provides a ground-locked intelligent charging pile and a method for using the same, comprising the following steps:

[0037] S1. When the vehicle drives to the position of the base 1 for charging, the license plate recognition camera 41 performs license plate recognition and comparison on the vehicle. If the license plate recognition result is an authorized vehicle, the motor 48 is automatically started to drive the blocking plate 44 to gradually lower, so that the vehicle can freely enter and exit the charging area for charging. If the license plate recognition result is an unauthorized vehicle, the motor 48 drives the blocking plate 44 to gradually rise to form a barrier to the vehicle;

[0038] S2. When the vehicle enters the warehouse and needs to be charged and the charging gun 21 is pulled out, an unlocking command is input on the control panel 31. The control system in the control panel 31 will compare the input unlocking command. If the unlocking command is correct, the control electromagnet 311 is energized to attract the armature plate 312 to drive the locking rod 314 to retract from the locking slot of the charging gun 21, thereby unlocking the charging gun 21.

[0039] S3, after unlocking the charging gun 21, the electric push rod 39 is started to extend and push the wedge-shaped top block 2 38 to slide in the slide groove 3, thereby driving the latch seat 310 to move synchronously, completely releasing the restriction on the charging gun 21, allowing the charging gun 21 to be pulled out for charging. On the contrary, if the unlocking instruction is wrong, the charging gun 21 will always be in a locked state and cannot be pulled out for charging;

[0040] S4. When the vehicle is fully charged, the charging gun 21 is inserted into the slot of the self-locking socket 32, thereby squeezing the squeezing plate 33 to compress the spring 1 34, and driving the wedge-shaped top block 1 35 to move, and finally driving the wedge-shaped top block 2 38 and the locking seat 310 and the internal locking rod 314 thereof to move toward the surface of the charging gun 21;

[0041] S5. As the charging gun 21 is continuously inserted, when the locking groove on the surface of the charging gun 21 is opposite to the end of the locking rod 314, under the elastic force of the spring 2 313, the locking rod 314 will be inserted into the locking groove to complete the locking of the charging gun 21, thereby preventing the private charging pile from being stolen by unauthorized personnel.

[0042] Working principle: When the vehicle drives to the position of the base 1 and needs to be charged, the license plate recognition camera 41 recognizes the license plate of the vehicle entering the area of ​​the charging pile body 2, and compares it with the preset authorized vehicle information through the control system in the control panel 31. If the license plate recognition result is an authorized vehicle, the motor 48 is automatically started to rotate forward to drive the screw rod 47 to rotate on the surface of the bottom plate 42, and then drive the threaded plate 46 to move linearly under the restriction of the slide rail 49. As the threaded plate 46 moves, it can drive the hinge rod 45 to push the blocking plate 44 to rotate around the hinge point with the positioning block 43, and then drive the blocking plate 44 to gradually lower, so that the vehicle can freely enter and exit the charging area for charging operations. If the license plate recognition result is determined to be an unauthorized vehicle, the motor 48 is started in the reverse direction, and the screw rod 47 rotates in the reverse direction, causing the threaded plate 46 to move in the reverse direction The hinge rod 45 moves, thereby driving the hinge rod 45 to pull the blocking plate 44 up, forming a barrier to the vehicles, preventing unauthorized vehicles from entering the charging area, ensuring that only authorized vehicles can use the charging pile, avoiding the charging pile being occupied by unrelated vehicles, ensuring the reasonable allocation and safe use of charging pile resources, and to a certain extent reducing the potential safety hazards caused by foreign vehicles entering the charging area, avoiding collisions and damages to the charging equipment caused by unauthorized vehicles forcibly entering, reducing the risk of accidental damage to the equipment, extending the service life of the charging pile, reducing maintenance costs, reducing interference with the charging area by unrelated vehicles, ensuring that the charging pile operates in a relatively stable environment, and helping to maintain its normal charging function and performance. The entire process does not require manual intervention, which provides great convenience for the charging operation of authorized vehicles and improves the management efficiency of the charging pile.

[0043] When the vehicle enters the warehouse and needs to be charged and the charging gun 21 is pulled out, an unlocking instruction is input on the control panel 31, and the control system in the control panel 31 will compare the input unlocking instruction. If the unlocking instruction is correct, the control system in the control panel 31 will first control the electromagnet 311 to be energized, generate a magnetic field and attract the armature plate 312 to compress the spring 2 313 and drive the locking rod 314 to move, so that the locking rod 314 can be retracted from the locking slot of the charging gun 21. After the charging gun 21 is unlocked, the electric push rod 39 is started to extend and push the wedge-shaped top block 2 38 to slide in the slide groove 3, thereby driving the locking seat 310 to move synchronously, which can drive the locking rod 314 to completely detach from the surface of the charging pile body 2, release the restriction on the charging gun 21, and allow the charging gun 21 to be pulled out for charging. On the contrary, if the unlocking instruction is wrong, the charging gun 21 will always be in a locked state and cannot be pulled out for charging.

[0044] Furthermore, when the vehicle is fully charged and the charging gun 21 needs to be inserted into the slot of the self-locking socket 32, the charging gun 21 is inserted into the socket of the self-locking socket 32 ​​by aligning the gun head of the charging gun 21 with the socket of the self-locking socket 32. Then, the charging gun 21 will squeeze the squeezing plate 33. After the squeezing plate 33 is subjected to pressure, it will compress the spring 34 and slide into the self-locking socket 32. As the squeezing plate 33 moves, the wedge-shaped top block 35 fixed on the squeezing plate 33 will also move. The inclined end surface of the wedge-shaped top block 35 abuts against the trapezoidal top block 36, pushing the trapezoidal The top block 1 36 slides in the slide groove 1, and the trapezoidal top block 1 36 pushes the trapezoidal top block 2 37 to slide in the slide groove 2 through its inclined end surface, and the trapezoidal top block 2 37 then pushes the wedge-shaped top block 2 38 to slide in the slide groove 3. At this time, the electric push rod 39 is in an unactivated state, and the wedge-shaped top block 2 38 can move freely, thereby driving the latch seat 310 fixed on the wedge-shaped top block 2 38 to move synchronously. Through the movement of the latch seat 310, the latch rod 314 can be driven to move synchronously and approach the surface of the charging gun 21. When the latch seat 310 moves, the latch rod 314 can move synchronously and approach the surface of the charging gun 21. After the locking rod 314 contacts the surface of the charging gun 21, the spring 2 313 will be deformed and generate elastic force through the armature plate 312, so that there is a certain squeezing force between the locking rod 314 and the charging gun 21. As the charging gun 21 is continuously inserted, when the locking groove opened on the surface of the charging gun 21 is opposite to the end of the locking rod 314, under the elastic force of the spring 2 313, the locking rod 314 will be inserted into the locking groove to complete the locking of the charging gun 21. This not only effectively prevents the private charging pile from being stolen by unauthorized personnel, protects the rights and interests of the charging pile owner, prevents others from using the charging pile for charging without permission, and avoids illegal use of energy, but also effectively prevents unauthorized personnel from accidentally pulling out the charging gun 21, avoids possible safety accidents such as electric shock and equipment damage, and ensures the safety of charging operation. At the same time, the whole process does not require complicated manual operation, which is convenient for the normal use of users, ensures the standardization and safety of charging operation, improves the reliability of the use of the charging pile body 2, and extends its service life.

[0045] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.

When the vehicle is fully charged, the charging gun (21) is inserted into the slot of the self-locking socket (32), thereby squeezing the squeezing plate (33) to compress the spring 1 (34), and driving the wedge-shaped top block 1 (35) to move, and finally driving the wedge-shaped top block 2 (38) and the locking seat (310) and the internal locking rod (314) thereof to move toward the surface of the charging gun (21); S5. As the charging gun (21) is continuously inserted, when the locking groove provided on the surface of the charging gun (21) faces the end of the locking rod (314), under the elastic force of the second spring (313), the locking rod (314) will be inserted into the locking groove to complete the locking of the charging gun (21), thereby preventing the private charging pile from being stolen by unauthorized personnel.
