Description

Technical Field

[0001] This invention relates to the field of new energy vehicle charging pile technology, specifically to an anti-drag new energy vehicle charging pile. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the scale of charging infrastructure construction continues to expand, and charging piles have become an indispensable supporting equipment for the daily use of electric vehicles. Currently, common charging piles are mainly divided into two categories: AC slow charging piles and DC fast charging piles. Their basic structure includes the charging pile body, charging cable, and charging gun. During charging, the user inserts the charging gun into the vehicle's charging port, and the charging head at the front of the charging gun connects with the charging terminals inside the vehicle's charging port to achieve power transfer. To prevent the charging gun from accidentally falling off during charging, existing charging piles generally have a mechanical locking mechanism inside the charging gun. This mechanism uses a locking hook to engage with a locking groove inside the vehicle's charging port to ensure a stable connection between the charging gun and the vehicle.

[0003] However, in real-world usage scenarios, it is not uncommon for new energy vehicles to move unexpectedly or for the charging gun to be dragged by external forces during charging. For example, if a user leaves the vehicle while charging, if someone else accidentally starts the vehicle, or if the charging cable is run over or snagged by a pedestrian or vehicle, the charging gun and charging cable may be subjected to abnormal dragging. Because the charging gun is mechanically locked to the vehicle's charging port through a locking mechanism, when the dragging force exceeds the structural limits of the cable and charging gun, it can lead to minor issues such as damage to the insulation layer of the charging cable and breakage of the internal conductors, or even damage to the vehicle's charging port, breakage of electrical connection components inside the charging pile, or even serious safety accidents such as electric shock or short circuit fires due to exposed conductors.

[0004] In the prior art, such as the anti-towing car charging pile disclosed in CN115503529B, there is a fixed support block. A charging cable is fixedly installed on the right side of the car charging pile. The end of the charging cable away from the car charging pile is fixedly connected to the fixed support block. A charging plug is provided on the front of the fixed support block. Anti-pull straps are fixedly connected to the left and right sides of the charging plug. The ends of the two anti-pull straps away from the charging plug are fixedly connected to the fixed support block. A charging support block is fixedly connected to the back of the charging plug. Two short support blocks are fixedly connected to the back of the charging support block. This anti-towing car charging pile, by setting anti-pull straps and fixed support blocks, and through the cooperation between the fixed support block component and the anti-pull strap component, allows the fixed support block component to pull the charging plug through the anti-pull straps, thereby achieving the effect of pulling the plugged-in charging plug out of the charging slot.

[0005] However, this anti-towing car charging station has the following drawbacks in that it uses a pull strap to drag the charging plug: First, the anti-pull strap directly applies force to the charging plug, which may result in slow separation of the charging plug from the vehicle's charging port and easy damage to the charging plug. Furthermore, during the pulling process, the charging plug and the vehicle's charging port are in a state of electrical separation, which may pose a risk of electric shock and fire. Secondly, the exposed pull belt structure is prone to aging and wear over long-term use, making it difficult to guarantee reliability.

[0006] Therefore, there is an urgent need to design a drag-resistant new energy vehicle charging pile that can quickly separate the charging plug from the vehicle charging port and ensure reliability, so as to overcome the above-mentioned defects. Summary of the Invention

[0007] The technical solution of this invention is: an anti-drag new energy vehicle charging pile, comprising a charging pile body, a charging cable, a charging gun, and a locking mechanism. The charging gun is connected to the charging pile body via the charging cable. One end of the charging gun is a charging end, and the other end is a holding end. A charging head is slidably mounted on the charging end of the charging gun, and the charging gun is connected to the vehicle's charging port via the charging head. A locking mechanism is provided inside the charging gun. When the charging gun is connected to the vehicle, the locking mechanism locks the connection between the charging gun and the vehicle to ensure a stable connection. A power cut-off mechanism is also provided, which is used to cut off the connection between the charging head and the charging cable. The power cut-off mechanism includes a connecting pipe, a power socket, a moving base, a guide block, and a coupling rod. A power socket is fixedly mounted inside the charging pile body, and the power socket is electrically connected to the charging cable. A connecting tube is provided at the end of the charging head facing away from its charging port. The connecting tube slides through the power socket. A movable seat is provided at the end of the connecting tube away from the charging head. The movable seat is electrically connected to the charging head via a wire placed inside the connecting tube. Guide blocks are symmetrically provided on both sides of the power socket. The movable seat slides into the guide blocks. Coupling rods and coupling slots are provided on the opposite sides of the power socket and the movable seat. When the movable seat is tightly attached to the power socket, the coupling rods and coupling slots are engaged. The power socket and the movable seat are electrically connected through the engagement of the coupling rods and coupling slots. The charging cable is electrically connected to the charging head through the power socket, the movable seat, and the wire inside the connecting tube. When the movable seat is away from the power socket, the coupling rods and coupling slots are separated. At this time, there is no circuit between the charging cable and the charging head.

[0008] It also includes a release mechanism and an AI intelligent monitoring camera. The charging pile itself is equipped with an AI intelligent monitoring camera, which is used to monitor whether the vehicle connected to the charging gun has moved. When the AI ​​intelligent monitoring camera detects that the vehicle connected to the charging gun has moved, the release mechanism drives the charging head to disengage from the vehicle's charging port and simultaneously releases the locking mechanism, so that the charging gun is separated from the vehicle.

[0009] Furthermore, the locking mechanism includes a locking plate, a rotating shaft, a locking hook, and a return spring. The rotating shaft is rotatably mounted on the charging gun, and the locking plate is fixedly connected to the rotating shaft. The locking plate is located inside the charging gun, and a locking hook is provided at one end of the locking plate. The locking hook is located near the charging head and is used to lock with the locking groove in the vehicle's charging port to ensure a stable connection between the charging gun and the vehicle. A return spring is provided between the locking plate and the inner wall of the charging gun.

[0010] Furthermore, the release mechanism includes a cylinder and a wedge block. The cylinder is installed inside the charging gun, and the piston rod of the cylinder is connected to the charging head. The cylinder is used to push the charging head to slide along the inner cavity of the charging gun so that the charging head is separated from or connected to the vehicle charging port. A wedge block is provided on the locking plate, and an inclined surface is provided on the charging head. The wedge surface of the wedge block and the inclined surface are pressed together.

[0011] Furthermore, the charging pile is also equipped with a protection mechanism, which includes a second rotating shaft, a swing plate, a mounting plate, a roller limit group, a positioning seat, a magnetic block, and a photoelectric sensor. The second rotating shaft is rotatably mounted on the back of the charging pile body, and a swing plate is mounted on the second rotating shaft. Multiple sets of roller limit groups are set on the swing plate, and the charging cable passes through the roller limit groups. A mounting plate is set on the side of the swing plate facing the charging pile body, and a positioning seat adapted to the mounting plate is set on the side of the charging pile body facing the swing plate. Magnetic blocks that magnetically attract each other are set on the positioning seat and the mounting plate, and a photoelectric sensor is set on the positioning seat.

[0012] Furthermore, a fixing rod is provided on the side of the swing plate opposite to the charging pile body, which is vertically offset. A sleeve is sleeved on the fixing rod, and a return spring is provided between the sleeves.

[0013] Furthermore, a pressing block is provided at the end of the locking plate away from the locking hook, and the pressing block is located on the gripping end side.

[0014] Furthermore, the charging station itself is also equipped with an audible and visual alarm.

[0015] The beneficial effects are as follows: 1. The present invention is equipped with a release mechanism and an AI intelligent monitoring camera protection mechanism. When the AI ​​intelligent monitoring camera detects that the vehicle connected to the charging gun has moved, the control system controls the cylinder to move, so that the cylinder piston rod contracts and drives the charging head to retract, thereby realizing the physical separation of the charging head from the vehicle charging port and unlocking the locking mechanism, thus realizing the efficient separation of the charging gun from the vehicle.

[0016] 2. As the charging head retracts, it drives the moving base to separate from the power socket via the connecting tube, and the coupling rod disengages from the coupling slot. This achieves the goal of cutting off the electrical connection between the charging head and the charging cable at the same time as the charging head is removed from the vehicle's charging port, thus ensuring the safety of the separation process.

[0017] 3. When the cylinder drives the charging head to retract, the pressing action between the inclined end of the charging head and the wedge block causes the locking plate to rotate around the pivot, thereby separating the locking hook from the locking groove in the vehicle's charging port. This releases the physical lock of the locking mechanism on the connection between the charging gun and the vehicle, facilitating the separation of the charging gun from the vehicle.

Detailed Implementation

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0029] Example 1: A towing-resistant charging pile for new energy vehicles, such as Figure 1 and Figure 2 As shown, the device includes a charging pile body 1, a charging cable 2, and a charging gun 3. The charging gun 3 is connected to the charging pile body 1 via the charging cable 2. One end of the charging gun 3 is a charging end, and the other end is a gripping end 31. A charging head 32 is slidably mounted on the charging end of the charging gun 3, and the charging gun 3 connects to the vehicle's charging port through the charging head 32. Under normal conditions, the charging gun 3 is inserted into the gun holder of the charging pile body 1. When charging is needed, the charging gun 3 is removed from the gun holder and then inserted into the vehicle's charging port, so that the charging head 32 aligns with the vehicle's charging port. The charging pile body 1 can then charge the new energy vehicle via the charging cable 2 and the charging gun 3.

[0030] Furthermore, such as Figure 3 and Figure 4 As shown, a locking mechanism is provided inside the charging gun 3. When the charging gun 3 is connected to the vehicle, the locking mechanism locks the charging gun 3 to ensure a stable connection between the charging gun 3 and the vehicle. Specifically, the locking mechanism includes a locking plate 4, a rotating shaft 40, a locking hook 41, and a return spring 6. The rotating shaft 40 is rotatably mounted on the charging gun 3, and the locking plate 4 is fixedly connected to the rotating shaft 40. The locking plate 4 is located inside the charging gun 3, and a locking hook 41 is provided at one end of the locking plate 4. The locking hook 41 is positioned close to the charging head 32 and is used to lock with the locking groove in the vehicle's charging port to ensure a stable connection between the charging gun 3 and the vehicle. It is worth noting that the end of the locking plate 4 away from the locking hook 41 is fixedly connected to the rotating shaft 40; a return spring 6 is provided between the locking plate 4 and the inner wall of the charging gun 3. The return spring 6 is a compression spring, and its two ends are respectively connected to the top wall of the inner cavity of the charging gun 3 and the top of the locking plate 4. The return spring 6 in its natural state is as follows: Figure 3 As shown, the return spring 6 is used to keep the locking hook 41 locked to the locking groove in the vehicle charging port.

[0031] Furthermore, this charging station also includes a release mechanism, an AI intelligent monitoring camera 22, and a control system. The charging station body 1 is equipped with the AI ​​intelligent monitoring camera 22 and the control system (not shown in the figure). The AI ​​intelligent monitoring camera 22 is used to monitor whether the vehicle connected to the charging gun 3 has shifted. The control system is electrically connected to the AI ​​intelligent monitoring camera and has built-in algorithms and programs for the AI ​​intelligent monitoring camera 22. The charging gun 3 is equipped with a release mechanism, which drives the charging head 32 to disengage from the vehicle's charging port and simultaneously releases the locking mechanism, thus detaching the charging gun 3 from the vehicle. In use, when the charging head 32 in the charging gun 3 is inserted into the vehicle's charging port, the AI ​​intelligent monitoring camera 22 is powered on and records the position of the charging vehicle; when the charging head 32 is disengaged from the vehicle's charging port, the AI ​​intelligent monitoring camera 22 is powered off. Therefore, when the charging gun 3 is connected to the vehicle, the AI ​​intelligent monitoring camera 22 can continuously monitor the vehicle connected to the charging gun 3. When the vehicle connected to the charging gun 3 is detected to be displaced, the control system controls the release mechanism to act, thereby driving the charging head 32 to disengage from the vehicle's charging port and simultaneously releasing the locking mechanism, so that the charging gun 3 actively disengages from the vehicle.

[0032] Specifically, such as Figures 3-5 As shown, the release mechanism includes a cylinder 8 and a wedge block 7. The cylinder 8 is installed inside the charging gun 3. The piston rod of the cylinder 8 is connected to the charging head 32. The cylinder 8 is used to push the charging head 32 to slide along the inner cavity of the charging gun 3, causing the charging head 32 to separate from or connect to the vehicle's charging port. When the charging gun 3 is connected to the vehicle's charging port, the control system controls the piston rod of the cylinder 8 to extend, causing the charging head 32 to be positioned at the charging end of the charging gun 3 (e.g., ...). Figure 3 As shown in the diagram, this ensures that the charging head 32 can connect with the vehicle's charging port, achieving an electrical connection and charging the vehicle. When the charging gun 3 separates from the vehicle's charging port, the control system controls the piston rod of the cylinder 8 to retract, causing the charging head 32 to retract into the inner cavity of the charging gun 3. A wedge-shaped block 7 is provided on the bottom wall of the locking plate 4, and an inclined surface 321 is provided on the charging head 32. The wedge-shaped surface of the wedge-shaped block 7 and the inclined surface 321 are pressed together. When the piston rod of the cylinder 8 retracts, the charging head 32 retracts into the inner cavity of the charging gun 3, and the inclined surface 321 of the charging head 32 presses against the wedge-shaped block 7, causing the locking plate 4 to rotate away from the charging head 32 around the pivot 40. This causes the locking hook 41 to move away from the locking groove of the vehicle's charging port, thereby releasing the locking of the locking hook 41 and the locking groove, thus releasing the connection between the charging gun 3 and the vehicle, and facilitating the separation of the charging gun 3 from the vehicle.

[0033] In addition, a pressing block 42 is provided at the end of the locking plate 4 away from the locking hook 41. The pressing block 42 is located on the side of the grip end 31. By pressing the pressing block 42 downward, the locking plate 4 is rotated around the rotating shaft 40, so as to separate the locking hook 41 from the locking groove at the vehicle charging port, thereby facilitating the separation of the charging gun 3 from the vehicle.

[0034] Furthermore, such as Figure 1 As shown, the charging pile body 1 is also equipped with an audible and visual alarm 21. The audible and visual alarm 21 is electrically connected to the control system. When the protection mechanism detects that the charging cable 2 and the charging gun 3 are being dragged, the control system controls the audible and visual alarm 21 to issue an audible and visual alarm.

[0035] When charging a new energy vehicle, the user inserts the charging gun 3 into the vehicle's charging port, and the charging head 32 aligns with the vehicle's charging port; the locking plate 4 in the locking mechanism, under the elastic force of the return spring 6, remains as follows. Figure 3 As shown, the locking hook 41 is engaged in the locking groove inside the vehicle's charging port, thereby achieving mechanical locking between the charging gun 3 and the vehicle. The charging pile body 1 then charges the new energy vehicle normally through the charging cable 2 and the charging gun 3.

[0036] During charging, the AI ​​intelligent monitoring camera 22 monitors the vehicle connected to the charging gun 3 in real time. When the AI ​​intelligent monitoring camera 22 detects that the vehicle has moved, the control system sends an action command to the cylinder 8. The piston rod of the cylinder 8 performs a contraction movement, causing the charging head 32 to retract along the inner cavity of the charging gun 3 towards the gripping end 31, thus physically separating the charging head 32 from the vehicle's charging port. During the retraction of the charging head 32, the inclined surface 321 on the charging head 32 and the wedge block 7 on the locking plate 4 engage in a pressing fit, forcing the locking plate 4 to overcome the elastic force of the return spring 6 and rotate around the pivot 40 in a direction away from the charging head 32. This causes the locking hook 41 to disengage from the locking groove in the vehicle's charging port, releasing the locking mechanism from locking the charging gun 3. At this time, there is neither an electrical connection nor a mechanical lock between the charging gun 3 and the vehicle. The charging gun 3 can be smoothly separated from the vehicle under external force, thus effectively avoiding damage to the charging cable 2, the charging gun 3, and even the charging pile body 1 due to dragging.

[0037] At the same time, the control system controls the audible and visual alarm 21 to emit an audible and visual alarm signal to alert surrounding personnel to safety and to stay away from dangerous areas.

[0038] Example 2: Based on Example 1, this charging station is further equipped with a protection mechanism. This mechanism monitors whether the charging cable 2 and charging gun 3 are being dragged. When the charging gun 3 and charging cable 2 connected to the vehicle are dragged, the protection mechanism is triggered. After the protection mechanism is triggered, the control system controls the piston rod of the cylinder 8 in the release mechanism to retract, thereby driving the charging head 32 to disengage from the vehicle's charging port and releasing the locking mechanism. Specifically, as shown... Figures 7-9 As shown, the protection mechanism includes a second rotating shaft 14, a swing plate 15, a mounting plate 151, a roller limit group 16, a positioning seat 17, a magnetic block 18, and a photoelectric sensor 19. The second rotating shaft 14 is rotatably arranged on the back of the charging pile body 1. The swing plate 15 is mounted on the second rotating shaft 14. The swing plate 15 is provided with no less than two sets of roller limit groups 16. The charging cable 2 passes through the roller limit group 16. The roller limit group 16 is used to limit the charging cable 2. Each set of roller limit groups 16 includes two rotatably arranged limit rollers. The charging cable 2 passes between the two limit rollers. A mounting plate 151 is provided on the side of the swing plate 15 facing the charging pile body 1. A positioning seat 17 adapted to the mounting plate 151 is provided on the side of the charging pile body 1 facing the swing plate 15. Magnetic blocks 18 are provided on the positioning seat 17 and the mounting plate 151, and a photoelectric sensor 19 is provided on the positioning seat 17. When the charging gun 3 and the charging cable 2 are in a normal state, the swing plate 151 is within the range monitored by the photoelectric sensor 19. When the charging gun 3 is dragged without detaching from the vehicle charging port, the charging gun 3 drives the swing plate 151 to rotate around the axis via the charging cable 2. When the swing plate 151 deviates from the monitoring range of the photoelectric sensor 19, the control system controls the cylinder 8 to move. The piston rod of the cylinder 8 retracts, thereby separating the charging head 32 from the vehicle charging port. At the same time, the inclined surface 321 of the charging head 32 and the wedge block 7 are pressed together, causing the locking plate 4 to rotate around the pivot 40, thereby separating the locking hook 41 from the locking groove at the vehicle charging port. This effectively separates the charging gun 3 from the vehicle, preventing the charging gun 3 and the charging cable 2 from being dragged and damaged. This provides passive protection for the charging gun 3 and the charging cable 2.

[0039] Furthermore, such as Figure 8 and Figure 9 As shown, a fixed rod 200 is provided on the lower part of the swing plate 15 facing the charging pile body 1, and a fixed rod 200 is also provided on the upper part of the charging pile body 1 facing the swing plate 15. A sleeve 201 is fitted onto each of the two fixed rods 200, and the sleeve 201 can rotate freely around the fixed rod 200. A second return spring 20 is provided between the two sleeves 201. The second return spring 20 is a tension spring, and its natural state is as follows: Figure 8 and Figure 9 As shown. When dragging occurs, the charging cable 2 drives the swing plate 15 to swing around the rotating shaft 14 against the elastic force of the second reset spring 20 and the magnetic attraction between the magnetic block 18; when the dragging force disappears, the second reset spring 20 drives the swing plate 15 to rotate around the rotating shaft 14 to reset, and the swing plate 15 is limited and fixed by the cooperation of the magnetic block 18.

[0040] When the vehicle moves unexpectedly due to misoperation and the AI ​​intelligent monitoring camera 22 fails to recognize the vehicle's displacement due to a malfunction, or when the charging gun 3 is dragged by an external force, the dragging force is transmitted to the swing plate 15 through the charging cable 2. This causes the swing plate 15 to overcome the elastic force of the return spring 20 and the magnetic attraction between the magnetic blocks 18, and to deflect around the rotating shaft 14. The mounting plate 151 deflects with the swing plate 15. When the deflection range of the mounting plate 151 exceeds the monitoring range of the photoelectric sensor 19 on the positioning seat 17, the control system controls the cylinder 8 to retract, causing the piston rod of the cylinder 8 to retract into the charging gun 3. The release mechanism then actuates, separating the charging gun 3 from the vehicle's charging port, thereby preventing damage to the charging gun 3 and the charging cable 2 due to the vehicle's dragging.

[0041] When the external drag force disappears, the swing plate 15 rotates in the opposite direction around the rotating shaft 14 under the elastic restoring force of the second reset spring 20. At the same time, the swing plate 15 is limited and fixed in the initial position by the mutual magnetic attraction between the magnetic blocks 18. The mounting plate 151 exits the detection area of ​​the photoelectric sensor 19, the resistance value of the photoelectric sensor 19 returns to the normal range, the system automatically resets, and waits for the next charging operation.

[0042] Example 3: Based on Example 2, such as Figures 3-6 As shown, this charging station is also equipped with a power cut-off mechanism, which is used to cut off the connection between the charging head 32 and the charging cable 2. The power cut-off mechanism includes a connecting pipe 5, a power base 9, a movable base 10, a guide block 11, and a coupling rod 12. The power base 9 is fixedly installed inside the charging station body 1. The power base 9 is electrically connected to the charging cable 2. The end of the charging head 32 facing away from its charging port is provided with a connecting pipe 5. The connecting pipe 5 slides through the power base 9. The end of the connecting pipe 5 away from the charging head 32 is provided with a movable base 10. The movable base 10 is electrically connected to the charging head 32 through a wire. The connecting wire is placed inside the connecting tube 5; guide blocks 11 are symmetrically arranged on both sides of the power base 9, and the movable seat 10 slides with the guide blocks 11. The power base 9 and the movable seat 10 are respectively provided with a coupling rod 12 and a coupling slot 13 on the opposite side. When the movable seat 10 is tightly attached to the power base 9, the coupling rod 12 and the coupling slot 13 are inserted and engaged. The power base 9 and the movable seat 10 are electrically connected through the insertion and engagement of the coupling rod 12 and the coupling slot 13. The charging cable 2 is electrically connected to the charging head 32 through the wires in the power base 9, the movable seat 10 and the connecting tube 5.

[0043] As the charging head 32 retracts, the charging head 32 drives the moving seat 10 to slide away from the power supply seat 9 along the guide block 11 through the connecting tube 5, so that the moving seat 10 separates from the power supply seat 9, and the coupling rod 12 disengages from the coupling slot 13, thereby cutting off the electrical connection between the charging head 32 and the charging cable 2, ensuring that physical power is cut off at the same time as the charging head 32 separates from the vehicle charging port, further ensuring the safety and reliability of the separation process.
