Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a vehicle wireless charging pile that performs charging by utilizing the wireless charging principle. 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 gas pump in a gas station. It can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It 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, charging methods similar to wireless charging of mobile phones have gradually expanded to the field of new energy vehicles. For wireless charging piles of new energy vehicles, the charging part usually includes a wireless charging head fixedly installed on the ground of the parking space, and a wireless charging receiving module that matches the wireless charging head is set on the chassis of the new energy vehicle. Since the length of the power transmission line affects the loss, in order to reduce the loss, the wireless charging receiving module is set on the battery of the vehicle chassis. When charging, the driver adjusts and adjusts the parking position of the vehicle according to the position of the wireless charging head, so that the vehicle is parked above the wireless charging head, so that the position of the vehicle's wireless charging receiving module corresponds to the position of the wireless charging head, and the wireless charging head and the wireless charging receiving module cooperate with each other to perform wireless charging. However, when using the above method for wired charging, there are the following disadvantages: 1) In order to reduce losses during wireless charging, the wireless charging receiving module is usually located at the battery position of the vehicle chassis to reduce the transmission distance and reduce losses. Due to different types of vehicles, the battery position of the vehicle chassis is different. In addition, the position of the wireless charging head fixedly installed on the ground of the parking space is also not fixed. Therefore, when wireless charging is performed, the wireless charging head and the battery cannot be well matched in position, resulting in poor adaptability of wireless charging for different models. Charging under poor adaptability leads to low charging efficiency 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 parking or reverse parking, there is still a position correspondence deviation for the fixed centerless charging head, which requires the driver to adjust, resulting in a poor driver experience; 3) For drivers with poor driving skills, when parking, it is easy for the center axis of the vehicle to be far away from the center axis of the parking space. In this case, in order to ensure better charging, the driver needs to adjust the vehicle frequently, resulting in more parking time, a more cumbersome process, and a poor experience. Therefore, it is urgent to design a wireless charging pile for a car that uses the principle of wireless charging to solve the above problems. Summary of the invention

A deflection box 39 and an angle adjustment mechanism drivingly connected to the deflection box 39 for adjusting the deflection angle of the deflection box 39 are arranged in the parking box 3. The deflection box 39 is a through structure with openings at both ends. The two openings of the through structure of the deflection box 39 are respectively connected to The parking space is connected to the parking ground above and the shell 1. When the angle adjustment mechanism drives the deflection box 39 to deflect, the two openings of the deflection box 39 are always located in the parking box 3. The wireless charging mobile vehicle 4 is located in the deflection box 39. The wireless charging mobile vehicle 4 is connected to an electric wire 13. The electric wire 13 passes through the deflection box 39 and the opening connecting the parking box 3 and the shell 1 in turn, and is connected to the built-in charging pile body 12. Preferably, the electric 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 a driving wheel 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 mobile driving motor drives the wheel body to rotate, thereby achieving the purpose of moving the wireless charging mobile vehicle 4. The retraction component is arranged in the shell 1, and the output end of the retraction component is connected to a retraction rope 11. The retraction rope 11 passes through the storage box 3 and the opening connecting the deflection box 39 and the shell 1 in sequence, and is connected to the wireless charging mobile vehicle 4, so that the retraction component can retract the wireless charging mobile vehicle 4 into the deflection box 39. Specifically, the retraction component includes a retraction motor 9,The shell 1 is provided with a mounting frame 8, the retracting motor 9 is arranged on the mounting frame 8, the output end of the retracting motor 9 is connected to the retracting roller 10, one end of the retracting rope 11 is connected to the retracting roller 10, the other end of the retracting rope 11 passes through the storage box 3 and the openings communicating with the deflection box 39 and the shell 1 in sequence, and is connected to the wireless charging mobile vehicle 4. Preferably, the retracting motor 9 adopts a motor without braking capability. When working, the rotor of the retracting motor 9 rotates relative to the stator. When not working, the stator of the retracting motor 9 will not generate braking force on the rotor. The rotor can rotate relative to the stator when subjected to external force. The angle adjustment mechanism includes a deflection angle adjustment motor 38, and a motor compartment is provided at the bottom of the storage box 3. 37, the deflection angle adjustment motor 38 is arranged in the motor compartment 37, and the output end of the deflection angle adjustment motor 38 is connected to the deflection box 39. A partition block 33 is arranged in the deflection box 39 near the opening connected to the shell 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 shell 1. A deflection box guide wheel 30 is arranged at the position of the partition block 33 in the deflection box 39. The retrieval rope 11 and the wire 13 are guided by the deflection box guide wheel 30. A limited guide wheel 40 is arranged at the opening of the deflection box 39 connected to the parking ground above the parking space. The identification component includes a thermal imaging probe for thermal imaging of the vehicle chassis to determine the battery position. The thermal imaging detector 15 is arranged in the parking ground of the parking space. Preferably, the thermal imaging detector 15 adopts a thermal imager, and the thermal imaging detector 15 is located in the middle of the parking space. A transparent protective plate 31 is arranged above the thermal imaging detector 15 in the parking ground of the parking space. A controller 14 is arranged in the shell 1, and 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 driving wheel 7 respectively, and the controller 14 is electrically connected to the retraction motor 9, and the controller 14 is electrically connected to the deflection angle The motor 38 is electrically connected to adjust the 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 enters the parking space, the recognition camera 36 recognizes 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 license plate information can be judged by the method of recognizing the license plate at the entrance and exit of the parking lot in the prior art. Since the recognition camera 36 is set on the parking space, when recognizing, when the vehicle license plate appears in the recognition range of the recognition camera 36, ​​recognition begins. Preferably, the recognition range angle of the recognition camera 36 is 100°-150°. When the vehicle drives to the parking space at a certain distance from the recognition camera 36, ​​the license plate information is transmitted to the controller 14.The range of a certain distance is 40cm-80cm. With the cooperation of the recognition range angle and the distance range of the recognition camera 36, ​​the license plate can still be recognized when the parking position of the vehicle is relatively biased, and at the same time, it can avoid the situation of misidentification when the vehicle has not entered. The chassis of the vehicle is thermally imaged by the thermal imaging detector 15. During the use of electric vehicles, the temperature of the vehicle chassis battery is significantly different from the temperature of other surrounding components, and the area of ​​the battery projected onto the ground is usually large. Therefore, with the help of the thermal imaging detector 15, the position of the battery can be effectively identified. Furthermore, the battery thermal image can be used as the position determination point based on the battery thermal image, and the battery thermal image can be close to the center position as the position determination point. At the same time, since the current is transmitted in the line When the length of the line affects the loss of electric energy, in order to reduce the loss of current during the transmission process, the wireless charging receiving module is installed at the battery position of the chassis of the car that can be wirelessly charged, so that the position of the wireless charging receiving module can be determined by identifying the battery position. After the thermal imaging detector 15 determines the battery position according to the thermal imaging result, the battery position information is transmitted to the controller 14. Under the action of the controller 14, when it is determined to be an electric car according to the license plate information, the deflection angle adjustment motor 38 drives the deflection box 39 to deflect the angle, so that the wireless charging mobile car 4 faces the battery position, and the wireless charging mobile car 4 passes through the car storage box 3 and the opening of the deflection box 39 connected to the parking ground above the parking space, and moves out of the deflection box 39 to the determined car. The lifting cylinder 5 drives the wireless charging head 6 to move upwards close to the battery, and by reducing the distance to the vehicle chassis, the loss is further reduced and the efficiency is improved. With the cooperation of the wireless charging head 6 and the wireless charging receiving module at the battery position of the vehicle chassis, wireless charging begins. When charging is completed, the vehicle drives away from the parking ground above the parking space. The recognition camera 36 cannot recognize the license plate information and transmits the license plate information-free signal to the controller 14. Under the action of the controller 14, the lifting cylinder 5 drives the wireless charging head 6 to move downwards, and the motor 9 is retracted to pull the wireless charging mobile vehicle 4 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 The angle position before the wireless charging mobile vehicle 4 is moved out is restored. Since the deflection box 39 is located at the end of the parking ground of the parking space, the deflection box 39 can be adapted to the vehicle chassis by a small deflection. In the above process, the built-in charging pile body 12 can always be in a working state, and can also be opened and closed according to the timing of the movement of the wireless charging mobile vehicle 4. The position of the vehicle chassis battery can be adapted through the wireless charging mobile vehicle 4, and the wireless charging receiving module at the position of the vehicle chassis battery can be adapted at the same time, so as to ensure the charging efficiency and avoid the situation where the driver needs to adjust the different parking positions of the vehicle due to driving habits, thereby improving the charging experience. Under the action of the deflection angle adjustment motor 38, the deflection angle of the deflection box 39 is adjusted.The deflection angle of the wireless charging mobile vehicle 4 is thereby adjusted so that the wireless charging mobile vehicle 4 is directed toward the battery position of the vehicle chassis before moving out of the deflection box 39, in order to cope with the situation where the parking position is relatively biased. By setting a limiting guide wheel 40, the wireless charging mobile vehicle 4 is guided and limited when the wireless charging mobile vehicle 4 moves to the deflection box 39, so that the wireless charging mobile vehicle 4 can be better moved into the deflection box 39. 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 connected to the parking ground above the parking space is in an inclined structure, so that the bottom of the opening of the storage box 3 is close to the parking space. The transition between the parking ground is smooth. At the same time, the bottom of the opening of the deflection box 39 connected to the parking ground above the parking space is inclined, so that the transition between the bottom of the opening of the deflection box 39 and the corresponding bottom of the opening of the parking box 3 is smooth, thereby avoiding affecting the entry and exit of the wireless charging mobile car 4. For the problem of charging after charging, since the recognition camera 36 is set to recognize the license plate, it can be combined with the parking fee payment end of the parking lot through the controller 14, and the charging fee can be paid together when the parking fee is paid. Regarding the setting of the thermal imaging detector 15, a thermal imager capable of thermal imaging setting can be directly selected, or it can be set by removing the transparent protective plate 31 and connecting it with an external computer.

Preferably, a groove body is provided on the top of the wire guiding lifting push rod 27, and the wire guiding motor 28 is provided on the groove wall of the groove body. The output end of the wire guiding motor 28 is connected to a wire guiding bottom wheel 29, and a wire guiding top wheel 25 is provided above the wire guiding bottom wheel 29 in the shell 1, and 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 from 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, thereby assisting the wire 13 to be retracted into the shell 1.

[0026] Combined with Figure 1-4As shown, a fixing plate 18 is arranged in the shell 1, and a sealing cylinder 19 is arranged on the fixing plate 18.

The sealing plate 21 passes through the parking ground of the parking space and is used to seal the opening connecting the storage box 3 with the parking ground above the parking space. The controller 14 is electrically connected to 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 connecting the storage box 3 with the parking ground above 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, and seals the opening connecting the storage box 3 with the parking ground above the parking space, thereby blocking external impurities.

By removing 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, and the heat generated by the built-in charging pile body 12 is absorbed by the heat dissipation water pipe 24. Subsequently, the coolant in the heat dissipation water pipe 24 enters the cavity in the car stopper 2, and heat is exchanged between the car stopper 2 and the outside of the shell 1, so as to achieve the effect of heat dissipation. The coolant after heat dissipation flows back to the water tank 23 through the reflux water pipe 34. Preferably, the car stopper 2 is made of metal material.

Under the coordination of the controller 14, when the recognition camera 36 identifies it as an electric car, the sealing plate 21 releases the seal of the opening connecting the storage box 3 and the parking ground above the parking space, and the wire guide lifting cylinder 26 drives the wire guide bottom wheel 29 to move downward, and the retraction motor 9 is in a non-working state. The deflection angle adjustment motor 38 drives the deflection box 39 to adjust the angle, and the wireless charging mobile car 4 moves out of the deflection box 39 and moves to the bottom of the battery. The lifting cylinder 5 drives the wireless charging head 6 to move online, and then it can Wireless charging is performed. After the wireless charging is completed and the vehicle leaves, the recognition camera 36 cannot recognize 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 guide lifting cylinder 26 drives the wire guide bottom wheel 29 to move upward, and cooperates with the wire guide top wheel 25 to clamp the wire 13. The retraction motor 9 starts working to pull the wireless charging mobile vehicle 4 to move into the deflection box 39, and the wire guide motor 28 works to assist in retracting the wire 13 into the shell 1.
