Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and particularly to a vehicle wireless charging pile that uses the principle of wireless charging for charging. Background Art

[0002] A charging pile refers to a charging device that provides energy replenishment for electric vehicles. Its function is similar to that of a fuel dispenser in a gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential community parking lots or charging stations, and can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is usually equipped with a charging plug for charging electric vehicles.

[0003] With the development of technology, a charging method similar to wireless charging of mobile phones has gradually been extended to the field of new energy vehicles. For the wireless charging pile of new energy vehicles, its charging part usually includes a wireless charging head fixedly installed on the ground of the parking space, and a wireless charging receiving module matching the wireless charging head is arranged on the chassis part of the new energy vehicle. Since the length of the electric energy transmission line affects the loss, in order to reduce the loss, the wireless charging receiving module is arranged on the vehicle chassis battery. When charging, the driver adjusts and adjusts the vehicle parking position according to the position of the wireless charging head so that the vehicle stops above the wireless charging head, making the wireless charging receiving module of the vehicle correspond to the position of the wireless charging head, and relying on the cooperation of the wireless charging head and the wireless charging receiving module to perform wireless charging. However, when charging using the above method, there are the following disadvantages: 1) In order to reduce the loss during wireless charging, the wireless charging receiving module is usually located at the position of the vehicle chassis battery to reduce the transmission distance and lower the loss. Due to the differences in vehicle types, the positions of the batteries on the vehicle chassis are different. In addition, the position of the wireless charging head fixedly installed on the ground of the parking space is not fixed either. Therefore, during wireless charging, the wireless charging head and the battery cannot be well position-matched, resulting in poor adaptability of wireless charging to different vehicle models. When charging under poor adaptability, the charging efficiency is low under the same power, thus affecting the overall charging effect; 2) For the same type of vehicle, due to different driving habits of drivers, such as different ways of driving in or reversing when parking, there is still a situation of position correspondence deviation for the fixed wireless charging head, and the driver needs to make adjustments, resulting in a poor driving experience for the driver; 3) For drivers with poor driving skills, when parking, it is easy to have a large distance between the central axis of the vehicle and the central axis of the parking space. In this case, in order to ensure better charging, the driver needs to frequently adjust the vehicle, resulting in a long parking time, a cumbersome process, and a poor experience. Therefore, it is urgently necessary to design a vehicle wireless charging pile that uses the principle of wireless charging to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is as follows: By providing a wireless charging head that can adapt to the position of the vehicle chassis battery capable of wireless charging and having a wireless charging receiving module, the charging efficiency can be ensured. At the same time, it can be adjusted according to different driving habits to improve the driving experience during wireless charging. In the case where the parking position is relatively off, there is no need for the driver to frequently adjust the vehicle position, reducing the parking time and improving the experience.

[0005] The technical solution adopted by the present invention to solve the technical problem is: A vehicle wireless charging pile that uses the principle of wireless charging, including: a housing, an internal charging pile body, a wireless charging mobile vehicle, a vehicle storage box, a retracting component, and an identification component:

[0006] The housing is buried below the parking ground of the parking space, and the internal charging pile body and the retracting component are arranged in the housing;

[0007] The vehicle storage box is located at the end of the parking space. The vehicle storage box has a through structure with openings at both ends. The two openings of the through structure of the vehicle storage box are respectively communicated with the upper part of the parking ground of the parking space and the housing. An identification camera for identifying the vehicle license plate is arranged on the parking ground of the parking space, and the identification camera is located on the side of the vehicle storage box away from the center of the parking space;

[0008] A deflection box and an angle adjustment mechanism for drivingly connecting with the deflection box to adjust the deflection angle of the deflection box are arranged in the vehicle storage box. The deflection box has a through structure with openings at both ends. The two openings of the through structure of the deflection box are respectively communicated with the upper part of the parking ground of the parking space and the housing. When the angle adjustment mechanism drives the deflection box to deflect, the two openings of the deflection box are always located inside the vehicle storage box, and the wireless charging mobile vehicle is located inside the deflection box;

[0009] The retracting component is arranged in the housing. A retracting rope is connected to the output end of the retracting component. The retracting rope sequentially passes through the openings of the vehicle storage box, the deflection box, and the housing that are communicated, and is connected to the wireless charging mobile vehicle.

[0012] When a vehicle drives into the parking space, the identification camera recognizes the vehicle license plate and transmits the license plate information to the controller. The thermal imaging detector recognizes the vehicle chassis to determine the battery position and transmits the battery position information to the controller. When the controller determines that the vehicle is an electric vehicle based on the license plate information, the angle adjustment mechanism adjusts the angle of the deflection box so that the wireless charging mobile vehicle faces the battery position. The wireless charging mobile vehicle passes through the deflection box and moves out from the opening where the deflection box and the parking box communicate with the parking ground above the parking space, and moves to the battery position. The built-in charging pile body transmits electric energy to the wireless charging mobile vehicle. When the charging is completed and the vehicle drives away from the parking space, the identification camera cannot recognize the license plate information and transmits the no-license-plate information signal to the controller, and the retracting assembly drives the wireless charging mobile vehicle to retract into the deflection box.

The other end of the retracting rope passes through the parking box and the opening where the deflection box communicates with the housing in sequence and is connected to the wireless charging mobile vehicle. The controller is electrically connected to the retracting motor.

[0015] As a preferred technical solution of the present invention, the angle adjustment mechanism includes a deflection angle adjustment motor. A motor chamber is opened at the bottom inside the parking box. The deflection angle adjustment motor is arranged in the motor chamber. The output end of the deflection angle adjustment motor is connected to the deflection box. A partition block is arranged inside the deflection box near the opening communicating with the housing. A deflection box guide wheel is arranged at the position of the partition block inside the deflection box. Both the retracting rope and the electric wire are guided by the deflection box guide wheel. A limiting guide wheel is arranged at the opening where the deflection box communicates with the parking ground above the parking space. The controller is electrically connected to the deflection angle adjustment motor.

[0016] As a preferred technical solution of the present invention, a wire guiding lifting cylinder is arranged inside the housing. The output end of the wire guiding lifting cylinder is connected to a wire guiding lifting push rod. A wire guiding motor is arranged at the end of the wire guiding lifting push rod. The output end of the wire guiding motor is connected to a wire guiding bottom wheel. A wire guiding top wheel is arranged above the wire guiding bottom wheel inside the housing. The wire passes through between the wire guiding top wheel and the wire guiding bottom wheel. The controller is electrically connected to the wire guiding lifting cylinder and the wire guiding motor.

[0017] As a preferred technical solution of the present invention, a fixing plate is arranged inside the housing. A sealing cylinder is arranged on the fixing plate. The output end of the sealing cylinder is connected to a sealing push rod. A sealing plate is arranged at the end of the sealing push rod. The sealing plate passes through the parking ground of the parking space to seal the opening communicating with the upper part of the parking ground of the parking space between the storage box and the parking space. The controller is electrically connected to the sealing cylinder.

[0018] As a preferred technical solution of the present invention, a water pump and a water tank are arranged inside the housing. Parking stop bars are arranged on the parking ground on both sides of the storage box. A cavity is formed inside the parking stop bars. The input end of the water pump is communicated with the water tank. The controller is electrically connected to the water pump.

[0019] As a preferred technical solution of the present invention, a heat dissipation water pipe is wound around the upper part of the built-in charging pile body. One end of the heat dissipation water pipe is communicated with the output end of the water pump. The other end of the heat dissipation water pipe is communicated with the cavity of the parking stop bar. One end of a return water pipe is connected to the water tank. The other end of the return water pipe is communicated with the cavity of the parking stop bar.

[0020] As a preferred technical solution of the present invention, a water inlet pipe is arranged on the water tank. The water inlet pipe penetrates through the parking ground of the parking space. A water tank cover is detachably installed on the water inlet pipe. The water tank cover is located in the parking ground of the parking space.

[0021] As a preferred technical solution of the present invention, a transparent protection plate is arranged at a position above the thermal imaging detector in the parking ground of the parking space.

[0022] The beneficial effects of the present invention are embodied in:

[0023] By setting up an identification camera, it is possible to judge the object moving to the parking space to determine whether it is an electric vehicle. By setting up a thermal imaging detector, it is used to determine the position of the vehicle chassis battery with a wireless charging module. Since the length of the power transmission line is correlated with the power loss, in order to ensure low loss, the wireless charging receiving module is located at the position of the vehicle chassis battery. Thus, by determining the battery position, the position of the wireless charging receiving module can be determined. Due to the setting of the wireless charging mobile vehicle, the deflection box, and the angle adjustment mechanism, according to the determined battery position, the angle adjustment mechanism adjusts the orientation of the wireless charging mobile vehicle. Subsequently, the wireless charging mobile vehicle moves to the position below the battery for wireless charging. After the charging is completed, the wireless charging mobile vehicle moves into the storage box to avoid obstructing other vehicles from parking on the parking ground of the parking space. Due to the existence of the wireless charging mobile vehicle that can move to adapt to the position of the vehicle chassis battery and the angle adjustment mechanism that can adjust the orientation of the wireless charging mobile vehicle, it is possible to adapt to different vehicle models, ensure the charging efficiency, and at the same time be able to adapt to different driving habits. After the vehicle is parked, wireless charging can be carried out without readjusting the vehicle again, thereby improving the charging experience of the driver. Moreover, in the case of a relatively remote parking position, the driver does not need to frequently adjust the vehicle position, reducing the parking time and further improving the experience.

[0024] Due to the setting of the lifting cylinder, it is possible to make the wireless charging head closer to the vehicle chassis, thereby further reducing the energy loss caused by the distance and improving the charging efficiency.

[0025] By setting up the wire guiding bottom wheel and the wire guiding top wheel that have driving ability and can move up and down, it is possible to assist in retracting the wire and prevent part of the wire from being left on the parking ground of the parking space after the wireless charging mobile vehicle moves into the storage box.

[0026] By setting up a movable sealing plate, when charging, the sealing plate releases the sealing of the opening connecting the storage box and the space above the parking ground of the parking space. After the charging is completed, the sealing plate seals the opening connecting the storage box and the space above the parking ground of the parking space to prevent impurities from entering.

[0027] By setting up a water pump, in cooperation with the heat dissipation water pipe, the return water pipe, and the parking block with a cavity, it can play a role in heat dissipation. Description of the Drawings

[0047] Combined with the attached Figure 1-6, as shown in FIGS. 8, 10 - 16, a vehicle wireless charging pile that charges using the principle of wireless charging includes: a housing 1, an internal charging pile body 12, a wireless charging mobile vehicle 4, a vehicle storage box 3, a retracting assembly, and an identification assembly. The housing 1 is buried below the parking ground of the parking space. The internal charging pile body 12 and the retracting assembly are arranged inside the housing 1. The vehicle storage box 3 is located at the end of the parking space. The vehicle storage box 3 has a through - structure with openings at both ends. The two openings of the through - structure of the vehicle storage box 3 are respectively communicated with the upper part of the parking ground of the parking space and the housing 1. Preferably, the vehicle storage box 3 is arranged in an inclined form at the end of the parking ground of the parking space. The end of the parking space is based on the length direction of the parking space. Among them, the connection line between the bottom of the opening of the vehicle storage box 3 communicated with the upper part of the parking ground of the parking space and the top of the opening communicated with the housing 1 is parallel to the horizontal plane. An identification camera 36 for identifying the vehicle license plate is arranged on the parking ground of the parking space. Preferably, the identification camera 36 is higher than the parking ground of the parking space. The identification camera 36 is located on the side of the vehicle storage box 3 away from the center of the parking space. Preferably, with the center of the parking space as the origin, the vehicle storage box 3 and the identification camera 36 are sequentially arranged on the central axis extension line extending from the center of the parking space to both ends. A deflection box 39 and an angle adjustment mechanism for drivingly connecting with the deflection box 39 to adjust the deflection angle of the deflection box 39 are arranged inside the vehicle storage box 3. The deflection box 39 has a through - structure with openings at both ends. The two openings of the through - structure of the deflection box 39 are respectively communicated with the upper part of the parking ground of the parking space and the housing 1. When the angle adjustment mechanism drives the deflection box 39 to deflect, the two openings of the deflection box 39 are always located inside the vehicle storage box 3. The wireless charging mobile vehicle 4 is located inside the deflection box 39. A wire 13 is connected to the wireless charging mobile vehicle 4. The wire 13 sequentially passes through the deflection box 39 and the openings of the vehicle storage box 3 and the housing 1 that are communicated, and is connected to the internal charging pile body 12. Preferably, the wire 13 has a certain elasticity. The wireless charging mobile vehicle 4 includes a vehicle body 401, a lifting cylinder 5, a wireless charging head 6, and driving wheels 7. The lifting cylinder 5 is arranged on the vehicle body 401. The output end of the lifting cylinder 5 is connected to the wireless charging head 6. The wireless charging head 6 is electrically connected to the wire 13 through the vehicle body 401. The driving wheels 7 are arranged at the bottom of the vehicle body 401. Preferably, the number of the driving wheels 7 is four, and the four driving wheels are evenly arranged at the bottom of the vehicle body 401. The driving wheel 7 includes a mobile driving motor and a wheel body. The mobile driving motor drives the wheel body to rotate, so as to achieve the purpose of moving the wireless charging mobile vehicle 4. The retracting assembly is arranged inside the housing 1. The output end of the retracting assembly is connected to a retracting rope 11. The retracting rope 11 sequentially passes through the vehicle storage box 3 and the openings of the deflection box 39 and the housing 1 that are communicated, and is connected to the wireless charging mobile vehicle 4, so that the retracting assembly can retract the wireless charging mobile vehicle 4 into the deflection box 39. Specifically, the retracting assembly includes a retracting motor 9,An installation frame 8 is provided inside the housing 1. The retraction motor 9 is arranged on the installation frame 8. The output end of the retraction motor 9 is connected to a retraction roller 10. One end of the retraction rope 11 is connected to the retraction roller 10. The other end of the retraction rope 11 sequentially passes through the opening where the storage box 3, the deflection box 39 and the housing 1 communicate, and is connected to the wireless charging mobile vehicle 4. Preferably, the retraction motor 9 is a motor without braking ability. During operation, the rotor of the retraction motor 9 rotates relative to the stator. When not working, the stator of the retraction motor 9 does not generate a braking force on the rotor, and the rotor can rotate relative to the stator when subjected to an external force. The angle adjustment mechanism includes a deflection angle adjustment motor 38. A motor chamber 37 is opened at the bottom inside the storage box 3. The deflection angle adjustment motor 38 is arranged in the motor chamber 37. The output end of the deflection angle adjustment motor 38 is connected to the deflection box 39. A partition block 33 is arranged inside the deflection box 39 near the opening communicating with the housing 1. Under the action of the partition block 33, the wireless charging mobile vehicle 4 can be supported to prevent the wireless charging mobile vehicle 4 from falling from the deflection box 39 into the housing 1. A deflection box guide wheel 30 is arranged at the position of the partition block 33 inside the deflection box 39. Both the retraction rope 11 and the wire 13 are guided by the deflection box guide wheel 30. A limit guide wheel 40 is arranged at the opening where the deflection box 39 communicates with the parking ground above the parking space. The identification component includes a thermal imaging detector 15 for performing thermal imaging on the vehicle chassis to judge the battery position. The thermal imaging detector 15 is arranged inside the parking ground of the parking space. Preferably, the thermal imaging detector 15 uses a thermal imager. The thermal imaging detector 15 is located at the middle position of the parking space. A transparent protection plate 31 is arranged at the position above the thermal imaging detector 15 in the parking ground of the parking space. A controller 14 is arranged inside the housing 1. The controller 14 is electrically connected to the thermal imaging detector 15, the built-in charging pile body 12, the wireless charging mobile vehicle 4, the retraction component, the identification camera 36 and the angle adjustment mechanism respectively. Specifically, the controller 14 is electrically connected to the lifting cylinder 5, the wireless charging head 6 and the drive wheel 7 respectively. The controller 14 is electrically connected to the retraction motor 9. The controller 14 is electrically connected to the deflection angle adjustment motor 38. First, the vehicle capable of wireless charging is an electric vehicle and is equipped with a wireless charging receiving module. When the vehicle drives into the parking space, the identification camera 36 identifies the license plate of the vehicle and transmits the license plate information to the controller 14. The license plate information is judged in the controller 14. The judgment method of the license plate information can be carried out by using the method of license plate recognition at the entrance and exit of the parking lot in the prior art. Since the identification camera 36 is arranged on the parking space, during identification, when the license plate of the vehicle appears within the identification range of the identification camera 36, the identification starts. Preferably, the identification range angle of the identification camera 36 is 100°-150°. When the vehicle is at a certain distance from the identification camera 36 when driving towards the parking space, the license plate information is transmitted to the controller 14.The range of a certain distance is between 40 cm and 80 cm. With the cooperation of the recognition range angle and distance range of the recognition camera 36, even when the vehicle parking position is relatively off, the license plate can still be recognized, while avoiding misrecognition when the vehicle has not entered. Under the action of the thermal imaging detector 15, thermal imaging of the vehicle chassis is performed. Since during the use of electric vehicles, there is an obvious difference in temperature between the vehicle chassis battery and other surrounding components, and the area projected by the battery onto the ground is usually large, the position of the battery can be effectively recognized with the help of the thermal imaging detector 15. Further, based on the thermal imaging map of the battery, the center position of the battery thermal imaging map is used as the position determination point. At the same time, since the length of the line affects the power loss when the current is transmitted in the line, in order to reduce the power loss during the transmission of the current, a wireless charging receiving module is installed at the position of the chassis battery of the vehicle capable of wireless charging. Thus, once the battery position is recognized, the position of the wireless charging receiving module can be determined. After the thermal imaging detector 15 determines the battery position based on the thermal imaging result, it transmits the battery position information to the controller 14. Under the action of the controller 14, when it is determined to be an electric vehicle based on the license plate information, the deflection angle adjustment motor 38 drives the deflection box 39 to deflect, so that the wireless charging mobile vehicle 4 moves towards the battery position. The wireless charging mobile vehicle 4 moves out of the deflection box 39 through the opening connecting the storage box 3 and the deflection box 39 with the parking ground above the parking space, and moves below the determined vehicle chassis battery. Subsequently, the lifting cylinder 5 drives the wireless charging head 6 to move upward close to the battery, reducing the distance to the vehicle chassis to further reduce losses and improve efficiency. With the cooperation of the wireless charging head 6 and the wireless charging receiving module at the position of the vehicle chassis battery, wireless charging starts. When the charging is completed, the vehicle drives away from above the parking ground of the parking space, and the recognition camera 36 cannot recognize the license plate information and transmits the no-license-plate information signal indicating that the license plate information cannot be recognized to the controller 14. Under the action of the controller 14, the lifting cylinder 5 drives the wireless charging head 6 to move downward, and the retracting motor 9 pulls the wireless charging mobile vehicle 4 to move into the deflection box 39. The deflection angle adjustment motor 38 drives the deflection box 39 to reset the deflection angle, so that the deflection box 39 returns to the angle position before the wireless charging mobile vehicle 4 moves out. Since the deflection box 39 is located at the end of the parking ground of the parking space, a small-angle deflection of the deflection box 39 can adapt to the vehicle chassis. During the above process, the built-in charging pile body 12 can always be in a working state or can be opened and closed according to the movement timing of the wireless charging mobile vehicle 4. The wireless charging mobile vehicle 4 can adapt to the position of the vehicle chassis battery and at the same time adapt to the wireless charging receiving module at the position of the vehicle chassis battery, thereby ensuring the charging efficiency and avoiding the situation where the driver needs to adjust due to different vehicle parking positions caused by driving habits, improving the charging experience. Under the action of the deflection angle adjustment motor 38, the deflection angle of the deflection box 39 is adjusted.Thus, the deflection angle of the wireless charging mobile vehicle 4 is adjusted so that the wireless charging mobile vehicle 4 faces the vehicle chassis battery position before moving out of the deflection box 39, in order to cope with the situation where the parking position is relatively off. By setting the limit guide wheels 40, when the wireless charging mobile vehicle 4 moves to the deflection box 39, the wireless charging mobile vehicle 4 can be guided and limited, so that the wireless charging mobile vehicle 4 can move into the deflection box 39 better. When the wireless charging mobile vehicle 4 enters and exits the storage box 3 and the deflection box 39, since there is a certain gap between the storage box 3 and the deflection box 39, preferably, the bottom of the opening of the storage box 3 communicating with the parking ground above the parking space is of an inclined structure, so that the transition between the bottom of the opening of the storage box 3 and the parking ground of the parking space is smooth. At the same time, the bottom of the opening of the deflection box 39 communicating with the parking ground above the parking space is of an inclined structure, so that the transition between the bottom of the opening of the deflection box 39 and the corresponding bottom of the opening of the storage box 3 is smooth, thus avoiding affecting the entry and exit of the wireless charging mobile vehicle 4. Regarding the charging and payment problem, since the identification camera 36 is set to identify the license plate, it can be combined with the parking charging terminal of the parking lot through the controller 14, and the charging fee can be paid together when paying the parking fee. Regarding the setting of the thermal imaging detector 15, a thermal imager that can perform thermal imaging setting can be directly selected, or it can be set by removing the transparent protection plate 31 and connecting it to an external computer and then setting it.

[0048] Combined with the attached Figure 1-6 As shown in FIGS. 8-9 and 12, a wire guiding lifting cylinder 26 is arranged in the housing 1. The output end of the wire guiding lifting cylinder 26 is connected to a wire guiding lifting push rod 27. The end of the wire guiding lifting push rod 27 is provided with a wire guiding motor 28. Preferably, a groove is formed at the top of the wire guiding lifting push rod 27, and the wire guiding motor 28 is arranged on the groove wall of the groove. The output end of the wire guiding motor 28 is connected to a wire guiding bottom wheel 29. A wire guiding top wheel 25 is arranged above the wire guiding bottom wheel 29 in the housing 1. The wire 13 passes between the wire guiding top wheel 25 and the wire guiding bottom wheel 29. The controller 14 is electrically connected to the wire guiding lifting cylinder 26 and the wire guiding motor 28. When the wireless charging mobile vehicle 4 moves out of the deflection box 39, under the action of the controller 14, the wire guiding lifting cylinder 26 drives the wire guiding bottom wheel 29 to move downward, releasing the clamping of the wire 13 when cooperating with the wire guiding top wheel 25. When the wireless charging mobile vehicle 4 moves to the deflection box 39, the wire guiding lifting cylinder 26 drives the wire guiding bottom wheel 29 to move upward, cooperating with the wire guiding top wheel 25 to clamp the wire 13. At the same time, the wire guiding motor 28 works to drive the wire guiding bottom wheel 29 to rotate, assisting the wire 13 to be retracted into the housing 1.

[0049] Combined with the attached Figure 1-4As shown, a fixing plate 18 is arranged inside the housing 1. A sealing cylinder 19 is arranged on the fixing plate 18. The output end of the sealing cylinder 19 is connected with a sealing push rod 20. A sealing plate 21 is arranged at the end of the sealing push rod 20. The sealing plate 21 passes through the parking ground of the parking space to seal the opening communicating the storage box 3 with the upper part of the parking ground of the parking space. The controller 14 is electrically connected with the sealing cylinder 19. Before the wireless charging mobile vehicle 4 moves out of the deflection box 39, under the action of the controller 14, the sealing cylinder 19 drives the sealing plate 21 to move downward, so that the opening communicating the storage box 3 with the upper part of the parking ground of the parking space is in an open state. After the wireless charging mobile vehicle 4 moves to the deflection box 39, the sealing cylinder 19 drives the sealing plate 21 to move upward to seal the opening communicating the storage box 3 with the upper part of the parking ground of the parking space, thereby blocking external impurities.

[0050] Combined with the attached Figure 1-7 As shown, a water pump 22 and a water tank 23 are arranged inside the housing 1. Stop bars 2 are arranged on the parking ground of the parking spaces on both sides of the storage box 3. A cavity is formed inside the stop bars 2. The input end of the water pump 22 is communicated with the water tank 23. The controller 14 is electrically connected with the water pump 22. A heat dissipation water pipe 24 is wound around the built-in charging pile body 12. One end of the heat dissipation water pipe 24 is communicated with the output end of the water pump 22. The other end of the heat dissipation water pipe 24 is communicated with the cavity of the stop bar 2. One end of a return water pipe 34 is connected to the water tank 23. The other end of the return water pipe 34 is communicated with the cavity of the stop bar 2. An inlet pipe 35 is arranged on the water tank 23. The inlet pipe 35 penetrates through the parking ground of the parking space. A water tank cover 32 is detachably installed on the inlet pipe 35. The water tank cover 32 is located in the parking ground of the parking space. By disassembling the water tank cover 32, the coolant in the water tank 23 can be replaced. During the charging process, under the action of the controller 14, the water pump 22 works to pump the coolant in the water tank 23 into the heat dissipation water pipe 24. The heat generated by the built-in charging pile body 12 is absorbed through the heat dissipation water pipe 24. Then the coolant in the heat dissipation water pipe 24 enters the cavity in the stop bar 2, and heat exchange is carried out with the outside of the housing 1 through the stop bar 2, so as to achieve the heat dissipation effect. The heat-dissipated coolant flows back to the water tank 23 through the return water pipe 34. Preferably, the stop bar 2 is made of metal material.

[0051] Combined with the attached Figure 1-4As shown, a wireless repeater 17 and a picture / video camera 16 are also provided inside the housing 1. Both the wireless repeater 17 and the picture / video camera 16 are electrically connected to the controller 14. Preferably, the picture / video camera 16 is located below the transparent protection plate 31. The wireless repeater 17 interacts with the driver's mobile phone through wireless interaction. The wireless interaction method can be selected as Bluetooth or Wi-Fi. The driver controls the controller 14 through the mobile phone and the wireless repeater 17, so that the picture / video camera 16 captures pictures and videos of the vehicle chassis, and judges the positions of the vehicle chassis battery and the wireless charging receiving module according to the captured results, so as to manually locate the vehicle chassis battery for the wireless charging mobile vehicle 4 to perform wireless charging.

[0052] Working principle: When wireless charging is required and the vehicle drives into the parking space, the identification camera 36 identifies the license plate information of the vehicle and transmits the license plate information to the controller 14. The thermal imaging detector 15 performs thermal imaging on the vehicle chassis to judge the battery position and transmits the battery position information to the controller 14. Under the coordination of the controller 14, when the identification camera 36 identifies an electric vehicle, the sealing plate 21 releases the seal of the opening connecting the storage box 3 and the space above the parking ground of the parking space. The wire guiding lifting cylinder 26 drives the wire guiding bottom wheel 29 to move downward, and the retracting motor 9 is in an idle state. The deflection angle adjustment motor 38 drives the deflection box 39 to adjust the angle. The wireless charging mobile vehicle 4 moves out of the deflection box 39 and moves below the battery. The lifting cylinder 5 drives the wireless charging head 6 to move upward, and then wireless charging can be carried out. After the wireless charging is completed and the vehicle drives away, the identification camera 36 cannot identify the license plate information, and the controller 14 obtains a signal of no license plate information. The lifting cylinder 5 drives the wireless charging head 6 to move downward, and the wire guiding lifting cylinder 26 drives the wire guiding bottom wheel 29 to move upward, cooperating with the wire guiding top wheel 25 to clamp the wire 13. The retracting motor 9 starts to work to pull the wireless charging mobile vehicle 4 into the deflection box 39. The wire guiding motor 28 works to assist in retracting the wire 13 into the housing 1. After the wireless charging mobile vehicle 4 moves into the deflection box 39, the deflection angle adjustment motor 38 resets the deflection box 39, and the sealing plate 21 seals the opening connecting the storage box 3 and the space above the parking ground of the parking space. During the charging process, the water pump 22 works to dissipate heat from the built-in charging pile body 12.
