Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a vehicle wireless charging pile based on 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 matching the wireless charging head is arranged 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 arranged 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 wireless charging receiving module of the vehicle 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 the loss during wireless charging, the wireless charging The power receiving module is usually located at the battery position of the vehicle chassis to reduce the transmission distance and reduce the loss. Due to different vehicle types, the battery position of the vehicle chassis is different. In addition, the position of the wireless charging head fixedly installed on the parking space floor 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 at 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 reversing, there is still a position correspondence deviation for the fixed centerless charging head, which requires the driver to make adjustments, resulting in a poor driver experience.

[0045] Combined with Figure 1-6, 8, 10-14, a car wireless charging pile based on the wireless charging principle, comprising: a shell 1, a built-in charging pile body 12, a wireless charging mobile car 4, a storage box 3, a retrieval component and an identification component, the shell 1 is buried under the parking ground of the parking space, the built-in charging pile body 12 and the retrieval component are arranged in the shell 1, the storage box 3 is located at the end of the parking space, the storage box 3 is a through structure with openings at both ends, preferably, the storage box 3 is a rectangular structure, the two openings of the through structure of the storage box 3 are respectively connected to the upper parking ground of the parking space and the shell 1, preferably, the storage box 3 is arranged at the end of the parking ground of the parking space in an inclined form, and the end of the parking space is based on the length direction of the parking space, wherein the storage box The line between the bottom of the opening connected to the parking ground above the parking space 3 and the top of the opening connected to the shell 1 is parallel to the horizontal plane. The storage box 3 is provided with an identification camera 36 for identifying the vehicle license plate on one side of the opening connected to the parking ground above the parking space. The wireless charging mobile car 4 is located in the storage box 3. The wireless charging mobile car 4 is connected with a wire 13. The wire 13 passes through the opening of the storage box 3 connected to the shell 1 and is connected to the built-in charging pile body 12. The wireless charging mobile car 4 includes a car body 41, a lifting cylinder 5, a wireless charging head 6 and a driving wheel 7. The lifting cylinder 5 is arranged on the car body 41. The output end of the lifting cylinder 5 is connected to the wireless charging head 6. The wireless charging head 6 is connected to the wire 13 through the car body 41. The driving wheel 7 is electrically connected, and is arranged at the bottom of the vehicle body 41. 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 41. The driving wheel 7 includes a mobile driving motor and a wheel body. 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 is connected to the wireless charging mobile vehicle 4 through an opening that is connected to the shell 1 through the storage box 3, so that the retraction component can retract the wireless charging mobile vehicle 4 into the storage box 3. Specifically, the retraction component includes a retraction motor 9, and a mounting frame 8 is arranged in the shell 1. The retraction motor 9 is arranged on the mounting frame 8, the output end of the retracting motor 9 is connected to a retracting roller 10, one end of the retracting rope 11 is connected to the retracting roller 10, and the other end of the retracting rope 11 passes through the opening of the storage box 3 connected to the shell 1 and is connected to the wireless charging mobile vehicle 4. Preferably, the retracting motor 9 adopts a motor without braking ability. 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. A partition block 33 is provided in the storage box 3 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 storage box 3 into the shell 1.A storage box guide wheel 30 is arranged at the position of the partition block 33 in the storage box 3, and the retrieval rope 11 and the wire 13 are guided by the storage box guide wheel 30. The identification component includes a thermal imaging detector 15 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 respectively connected to the thermal imaging detector 15, the built-in charging pile body 12, the wireless charging mobile car 4, the retrieval component and the identification camera The camera 36 is electrically connected. Specifically, the controller 14 is electrically connected to the lifting cylinder 5, the wireless charging head 6 and the driving wheel 7 respectively. The controller 14 is electrically connected to the retracting motor 9. First, the vehicle that can be wirelessly charged is an electric vehicle and has 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 box 3, when recognizing, the vehicle license plate appears in the recognition range of the recognition camera 36. It starts to be recognized. Preferably, the recognition camera 3 The recognition range angle of the camera 36 is 60°-100°. When the vehicle approaches the parking space at a certain distance from the recognition camera 36, ​​the license plate information is transmitted to the controller 14. The certain distance range is 10cm-30cm. With the cooperation of the recognition range angle and the distance range of the recognition camera 36, ​​the license plate can be recognized when the vehicle is parked in a relatively correct position, so as to avoid misidentification when the vehicle has not entered or the parking position is relatively biased. 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, so the position of the battery can be effectively detected with the help of the thermal imaging detector 15. At the same time, since the length of the line affects the loss of electric energy when the current is transmitted in the line, in order to reduce the loss of current during the transmission process, the wireless charging receiving module is installed at the chassis battery position 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 wireless charging mobile car 4 is moved out of the storage box 3 through the opening connecting the storage box 3 and the parking ground above the parking space, and moved to the bottom of the determined vehicle chassis battery. Then, the lifting cylinder 5 drives the wireless charging head 6 to move upward close to the battery.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 signal 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 parking box 3. Preferably, the bottom of the opening of the parking 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 parking box 3 and the parking ground of the parking space are smooth, thereby avoiding affecting the entry and exit of the wireless charging mobile vehicle 4. In the above process, the built-in charging pile body 1 2 can always be in working state, and can also be turned on and off according to the timing of the movement of the wireless charging mobile vehicle 4. The wireless charging mobile vehicle 4 can adapt the position of the vehicle chassis battery, and at the same time adapt the wireless charging receiving module of the vehicle chassis battery position, so as to ensure the charging efficiency, and at the same time avoid the situation that the driver needs to adjust the parking position of the vehicle due to driving habits, thereby improving the charging experience. 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 terminal of the parking lot through the controller 14, and the charging fee can be paid together when the parking fee is paid. For 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. ,

[0046] Combined with Figure 1-6, 8-9, and 12, a wire guiding lifting cylinder 26 is provided in the shell 1, and a wire guiding lifting push rod 27 is connected to the output end of the wire guiding lifting cylinder 26, and a wire guiding motor 28 is provided at the end of the wire guiding lifting push rod 27. Preferably, a groove body is provided on 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 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 through between the wire guiding top wheel 25 and the wire guiding bottom wheel 29. The controller 14 is electrically connected to the wire guide lifting cylinder 26 and the wire guide motor 28. When the wireless charging mobile vehicle 4 moves out of the storage box 3, under the action of the controller 14, the wire guide lifting cylinder 26 drives the wire guide bottom wheel 29 to move downward, releasing the clamping of the wire 13 when cooperating with the wire guide top wheel 25. When the wireless charging mobile vehicle 4 moves to the storage box 3, the wire guide lifting cylinder 26 drives the wire guide bottom wheel 29 to move upward, cooperating with the wire guide top wheel 25 to clamp the wire 13. At the same time, the wire guide motor 28 works to drive the wire guide bottom wheel 29 to rotate, thereby assisting the wire 13 to be retracted into the shell 1.

[0047] Combined with Figure 1-4 As shown, a fixing plate 18 is arranged in the shell 1, and a sealing cylinder 19 is arranged on the fixing plate 18. The output end of the sealing cylinder 19 is connected to a sealing push rod 20, and a sealing plate 21 is arranged at the end of the sealing push rod 20. The sealing plate 21 passes through the parking floor of the parking space and is used to seal the opening connecting the storage box 3 with the parking floor above the parking space. The controller 14 is electrically connected to the sealing cylinder 19. Before the wireless charging mobile vehicle 4 is moved out of the storage box 3, 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 floor above the parking space is in an open state. After the wireless charging mobile vehicle 4 moves to the storage box 3, the sealing cylinder 19 drives the sealing plate 21 to move upward, and seals the opening connecting the storage box 3 with the parking floor above the parking space, thereby blocking external impurities.

[0048] Combined with Figure 1-7As shown, a water pump 22 and a water tank 23 are arranged in the shell 1, and a car blocking rod 2 is arranged on the parking ground of the parking space on both sides of the storage box 3, and a cavity is opened in the car blocking rod 2, and the input end of the water pump 22 is connected with the water tank 23, and the controller 14 is electrically connected with the water pump 22, and a heat dissipation water pipe 24 is coiled on the built-in charging pile body 12, and one end of the heat dissipation water pipe 24 is connected with the output end of the water pump 22, and the other end of the heat dissipation water pipe 24 is connected with the cavity of the car blocking rod 2, and one end of a reflux water pipe 34 is connected to the water tank 23, and the other end of the reflux water pipe 34 is connected with the cavity of the car blocking rod 2, and a water inlet pipe 35 is arranged on the water tank 23, and the water inlet pipe 35 passes through the parking ground of the parking space, and the inlet pipe 35 passes through the parking ground of the parking space. A water tank cover 32 is detachably mounted on the water pipe 35, and the water tank cover 32 is located on the parking surface of the parking space. 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.

[0049] Combined with Figure 1-4 As shown, a wireless relay 17 and a picture and video camera 16 are also provided in the shell 1, and the wireless relay 17 and the picture and video camera 16 are both electrically connected to the controller 14. Preferably, the picture and video camera 16 is located below the transparent protective plate 31, and the wireless relay 17 interacts with the driver's mobile phone through wireless interaction, and the wireless interaction method selects Bluetooth mode, and can also select a wireless network mode. The driver controls the controller 14 through the mobile phone and the wireless relay 17, so that the picture and video camera 16 takes pictures and videos of the vehicle chassis, and determines the position of the vehicle chassis battery and the wireless charging receiving module according to the intake results, so as to manually position the vehicle chassis battery so that the wireless charging mobile vehicle 4 can perform wireless charging.

[0050] Working principle: When wireless charging is required and the vehicle enters the parking space, the recognition camera 36 recognizes the license plate information of the vehicle and transmits the license plate information to the controller 14, and the thermal imaging detector 15 performs thermal imaging of the vehicle chassis to determine the battery position and transmits the battery position information to the controller 14. 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 retracting motor 9 is in a non-working state. The wireless charging mobile car 4 is moved out of the storage box 3 and moved under the battery. The lifting cylinder 5 drives the wireless charging head 6 to move online, and then it can be started. 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.
