Description

Technical Field

[0001] This invention relates to the field of wireless charging technology for new energy vehicles, and in particular to a charging device and charging method for wireless intelligent charging of new energy vehicles. Background Technology

[0002] With the rapid development of the new energy vehicle industry, wireless charging technology has gradually become an important way to charge new energy vehicles due to its advantages such as no physical contact and convenient operation, especially suitable for outdoor parking lots, public charging stations and other scenarios.

[0003] Currently, most existing wireless charging devices for new energy vehicles are fixed in place, with the wireless charging transmitter in a fixed position. This makes it impossible to move and adjust the device according to the different charging positions on the floor of different new energy vehicles. As a result, drivers need to park precisely to achieve proper alignment, which is difficult to operate and inefficient. Moreover, if the wireless charging device were designed as a movable structure (such as moving and adjusting along the length and width of the vehicle) to solve the alignment problem, it would bring even more significant waterproofing challenges. Summary of the Invention

[0004] The purpose of this invention is to provide a charging device and charging method for wireless intelligent charging of new energy vehicles, addressing the problems of existing wireless charging for new energy vehicles, such as the inability to move and align properly, and poor waterproofing.

[0014] This invention also provides a charging method for a wireless intelligent charging device for new energy vehicles, comprising the following steps: Step 1: The vehicle drives into the wireless charging area and aligns its tires with the water-blocking platforms on both sides. The tires are all parked on the surface of the water-blocking platforms. The pressure sensors on the surface of the water-blocking platforms detect the tire pressure signal and transmit the signal to the controller. The controller confirms that the vehicle has been parked in place. Step two: After receiving the position signal from the pressure sensor, the controller activates the vision sensor. The vision sensor captures and identifies the charging position on the car floor in real time and transmits the position data to the controller. Based on the identification results, the controller synchronously controls the wireless charging component, the stacked longitudinal moving waterproof component, and the stacked lateral moving waterproof component to work together. Through the longitudinal movement of the wireless charging plate and the lateral movement of the entire vehicle, the wireless charging transmitter is aligned with the charging position on the car floor. After the longitudinal and lateral alignment is completed, the distance between the wireless charging transmitter and the charging position on the car floor is adjusted until the optimal wireless charging distance is reached, thus completing the overall alignment operation. Step 3: After alignment, activate the wireless charging transmitter to transmit power to the charging coil on the car floor and begin wireless charging. Step 4: During the charging process, water level sensor 1 and water level sensor 2 monitor the water level in the middle groove and the side groove in real time, respectively. Water level sensor 3 monitors the water level in the temporary storage cavity in real time. Water level sensor 4 monitors the water level in the leakage temporary storage tank in real time. Water level sensor 5 monitors the water level in the temporary storage cavity in real time. When the water level reaches the preset threshold, the main controller immediately issues an emergency power-off command and the controller cuts off the charging power.

[0015] The advantages and positive effects of the wireless intelligent charging device and charging method for new energy vehicles described in this invention are as follows: 1. Effectively adapts to the differences in charging positions of different car models, reduces the difficulty of alignment and improves the alignment efficiency. No need for precise parking by the driver. The charging position on the car floor is monitored in real time through a visual sensor. The longitudinal movement of the wireless charging component and the lateral movement of the vehicle are coordinated to achieve automatic and precise alignment between the wireless charging transmitter and the charging position on the car floor. At the same time, the spacing is adjusted by lifting to ensure stable wireless charging effect. 2. It solves the waterproofing problem of mobile wireless charging devices. Through the coordinated setting of stacked vertical moving waterproof components, stacked horizontal moving waterproof components, and stacked lifting moving waterproof components, a multi-layered protective structure is designed for the movement characteristics of each moving component. This effectively prevents rainwater from seeping into the device from the moving gaps, protects the core electrical and mechanical components, extends the service life of the device, and improves the safety of use. 3. Comprehensive water accumulation monitoring: Five water level sensors monitor the water levels in the central groove, side groove, bellows-style protective cover storage chamber, lifting protective cover leakage storage tank, and leakage storage box storage chamber, respectively. This allows for timely detection of potential water accumulation hazards, preventing electrical short circuits and other safety accidents caused by water accumulation, and further improving charging safety. 4. A wired charging backup function is added. A charging gun is installed on the support column. When the wireless charging system fails, the vehicle's emergency charging needs can be met through wired charging, improving the adaptability and practicality of the device.

[0020] In this application, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. In case of any inconsistency, the meaning set forth in this specification or derived from the content described herein shall prevail. Furthermore, the terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit the scope of this application.

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] Example: like Figure 1 As shown, the present invention discloses a wireless intelligent charging device for new energy vehicles, comprising a wireless charging area 1, with a rain shelter 2 disposed above the wireless charging area 1. The rain shelter 2 is fixed above the wireless charging area 1 by a support column 3 disposed on the wireless charging area 1, and the rain shelter 2 has a rainproof function, preventing rainwater from directly washing over the wireless charging area 1. A charging gun for wired charging of vehicles can be disposed on the support column 3, so that new energy vehicles can be charged via wired charging when wireless charging is unavailable.

[0023] A wireless charging component is positioned in the center of the wireless charging area 1. The component includes a mounting base 4, on which a wireless charging transmitter 5 and a vision sensor 6 are mounted. The vision sensor 6 monitors the charging position on the vehicle's floor in real time. The wireless charging component moves longitudinally along the length of the vehicle, coordinating with the vehicle's lateral movement along its width to align the wireless charging transmitter 5 with the charging position on the vehicle's floor. The distance between the wireless charging transmitter 5 and the charging position on the vehicle's floor can be adjusted by raising and lowering the component.

[0024] like Figure 2 , Figure 3, Figure 4 , Figure 5 As shown, the wireless charging assembly has stacked longitudinally moving waterproof components at both ends. The stacked longitudinally moving waterproof components include, from top to bottom, a water-blocking plate 7, a accordion-style protective cover 8, and a water-blocking plate 9. The widths of the water-blocking plate 7, the accordion-style protective cover 8, and the water-blocking plate 9 increase sequentially along the width of the vehicle (the width of the accordion-style protective cover 8 along the width of the vehicle is greater than the width of the water-blocking plate 7 along the width of the vehicle, and the width of the water-blocking plate 9 along the width of the vehicle is greater than the width of the accordion-style protective cover 8 along the width of the vehicle). The top of the wireless charging area 1 is a hardened plate 24, and the water-blocking plate 7 covers the hardened plate 24 and is slidably connected to the wireless charging area 1. The water-blocking plates 7 are symmetrically arranged at both ends of the wireless charging assembly, and the ends of the symmetrically arranged water-blocking plates 7 that are close to each other are fixed together by a water-blocking strip 10. A slider 12 is provided at the bottom of the water-blocking plate 7 and the water-blocking strip 10. A groove adapted to the slider 12 is provided on the hardened plate 24, and the slider 12 is inserted into the groove and slidably connected to the groove. A central groove 13 is provided below the water baffle 7, and the accordion-style protective cover 8 and the water baffle 9 are located in the central groove 13.

[0025] from Figure 1 As can be seen, the length of the water baffle 7 extends to both ends to accommodate the displacement of the water baffle 7 as it slides to both ends when the wireless charging component moves longitudinally. Figure 1 In this invention, the central rectangular area and the two extra small rectangular areas at both ends are the wireless charging area 1. The water-blocking plate 9 is located inside the groove, and its two ends extend outwards, similar to the water-blocking plate 7. The water-blocking plate 9 is slidably connected to the extended wireless charging area 1. One end of the accordion-style protective cover 8 is connected to the lifting protective cover 19, and the other end of the accordion-style protective cover 8 abuts against the inner end of the extended wireless charging area 1. Its extension and retraction will compress the internal temporary storage cavity 14, but its length design will not completely compress it, leaving a certain margin, which can fully store the small amount of water that leaks out. Its water inlet 15 will not be completely blocked by compression.

[0026] The accordion-style protective cover 8 is entirely enclosed, with its four sides retractable and its two ends sealed by a single piece of material (the accordion-style protective cover 8 and the end seals are integrally formed). The interior of the accordion-style protective cover 8 has a temporary storage cavity 14 for storing rainwater leaking from the baffle 7. The top side of the accordion-style protective cover 8 is concave in an arc shape, and several water inlets 15 communicating with the temporary storage cavity 14 are located in the center of the top side of the accordion-style protective cover 8. These water inlets 15 are arranged along the retraction direction of the accordion-style protective cover 8. A side groove is provided within the central groove 13, and the two sides of the accordion-style protective cover 8 are inserted into and slidably connected to the side groove. A side slot is provided within the central groove 13, and the two sides of the water-blocking plate 9 are inserted into and slidably connected to the side slot. A lifting opening 11 is provided in the center of the water-blocking plate 9. A waterproof platform 16 is provided at the bottom of the interior of the central groove 13, and a longitudinally moving seat 17 with longitudinal movement function is provided on the waterproof platform 16. The longitudinal moving seat 17 is driven to move by a lead screw structure, and the longitudinal moving seat 17 is connected to the bottom end of the mounting seat 4 through a lifting element 18.

[0027] The bottom of the wireless charging component is equipped with a layered, lifting, movable, waterproof component. This layered, laterally movable, waterproof component includes a lifting protective cover 19, which covers the outside of the mounting base 4. The lifting protective cover 19 and the mounting base 4 are connected as one unit by waterproof adhesive 20. A leakage storage groove 21 is provided inside the lifting protective cover 19 (used to temporarily store leaked water, preventing the waterproof adhesive 20 of the lifting protective cover 19 from aging, and allowing water to flow into the central groove 13 through gaps). The lifting protective cover 19 passes through the lifting opening 11 and is slidably connected to the water baffle 7, water baffle strip 10, accordion-style protective cover 8, water blocking plate 9, and central groove 13. Waterproof adhesive strip 22 is provided at the end of the water baffle 7, water baffle strip 10, accordion-style protective cover 8, and water blocking plate 9 that contacts the lifting protective cover 19. Several waterproof adhesive strips 23 are provided on the side of the central groove 13 that contacts the lifting protective cover 19. While not affecting the lifting and lowering of the protective cover 19, it prevents water from flowing into the middle groove 13 through the gaps, thus protecting the power components and other components inside the middle groove 13.

[0028] The longitudinal moving seat 17 is driven to move by a symmetrically arranged lead screw structure located on the waterproof platform 16. The motor of the lead screw structure drives the lead screw to rotate, thereby causing the longitudinal moving seat 17 to slide on the waterproof platform 16, realizing the longitudinal movement of the longitudinal moving seat 17. The lifting element 18 can be a hydraulic cylinder, and the related device providing hydraulic power is set on the waterproof platform 16.

[0029] like Figure 6 , Figure 7As shown, stacked horizontally moving waterproof components are symmetrically arranged on both sides of the wireless charging area 1 with respect to the wireless charging components. The stacked horizontally moving waterproof components include, from top to bottom, a water-blocking horizontal moving platform 25, a leak-proof storage box 26, and a water-blocking horizontal moving plate 27. The water-blocking horizontal moving platform 25 has inwardly recessed horizontal moving grooves on both sides. The hardened plate 24 of the wireless charging area 1 is inserted into the horizontal moving grooves and slidably connected to them. A hollow groove 29 is provided below the water-blocking horizontal moving platform 25, and a side groove 28 is provided below the hollow groove 29. The leak-proof storage box 26 and the water-blocking horizontal moving plate 27 are both located within the hollow groove 29 and above the side groove 28. The bottom end of the water-blocking horizontal moving plate 27 is slidably connected to the hollow groove 29 and covers the side groove 28. The leak-proof storage box 26 is located at the top of the water-blocking horizontal moving plate 27, and the top end of the leak-proof storage box 26 is connected to the bottom end of the water-blocking horizontal moving platform 25 via a support block 32. The leak storage tank 26 has a temporary storage cavity 30 for temporarily storing leaked water. The top of the leak storage tank 26 is concave in an arc shape. Several leak holes 31, communicating with the temporary storage cavity 30, are located in the center of the top of the leak storage tank 26. The leak holes 31 are arranged along the length of the leak storage tank 26 and are offset from the support block 32. The widths of the water-blocking transverse platform 25, the leak storage tank 26, and the water-blocking transverse plate 27 increase sequentially (the width of the leak storage tank 26 along the width of the vehicle is greater than the width of the water-blocking transverse platform 25 along the width of the vehicle, and the width of the water-blocking transverse plate 27 along the width of the vehicle is greater than the width of the leak storage tank 26 along the width of the vehicle).

[0030] A second waterproof platform 33 is installed inside the empty slot 29. A lateral moving seat 34 with lateral movement function is installed on the second waterproof platform 33. The lateral moving seat 34 is moved by a lead screw structure, and its top end is connected to the bottom end of the water-blocking transverse sliding plate 27. The lateral moving seat 34 is moved by symmetrically arranged lead screw structures located on the second waterproof platform 33. The motor of the lead screw structure drives the lead screw to rotate, thereby causing the lateral moving seat 34 to slide on the second waterproof platform 33, realizing the lateral movement of the lateral moving seat 34.

[0031] It also includes a controller, which is electrically connected to water level sensors 1, 2, 3, 4, and 5, a pressure sensor, lifting element 18, a lead screw structure, a wireless charging transmitter board 5, and a vision sensor 6. Water level sensors 1 and 2 are respectively located on the sides of waterproof platform 1 16 and waterproof platform 2 33. The pressure sensor is located on the upper surface of the water-blocking transverse platform 25 and is used to monitor the pressure of the vehicle tires on the water-blocking transverse platform 25. Water level sensors 1 and 2 are respectively used to monitor... The water level in the middle groove 13 and the side groove 28 is monitored by a water level sensor 3 located in the temporary storage cavity 14 of the bellows-style protective cover 8, a water level sensor 4 located in the leakage storage tank 21 of the lifting protective cover 19, and a water level sensor 5 located in the temporary storage cavity 30 of the leakage storage box 26 (the controller automatically cuts off the power after the target water level is reached). The wireless charging transmitter 5 and the vision sensor 6 are mounted on the mounting platform, and their surfaces are all waterproof.

[0032] Three controllers can be set, and the installation is as follows: Main controller (1 unit): Installed on the waterproof platform 16 inside the middle groove 13, with a separate sealed waterproof mounting box (fixed together with the waterproof platform 16), responsible for coordinating the collaborative work of the three controllers, controlling the wireless charging components (mounting base 4, wireless charging transmitter 5, vision sensor 6), controlling the longitudinal movement components (longitudinal movement base 17, lead screw structure), controlling the lifting components (lifting element 18, lifting protective cover 19), as well as summarizing and monitoring the water level and equipment status of all areas and issuing emergency power-off commands; Left-side controller (1 unit): Installed on the waterproof platform 23 inside the left-side groove 28, with a matching sealed waterproof mounting box (fixed together with the left-side waterproof platform 23). It is responsible for: controlling and monitoring the status of the left-side lateral movement component (left-side lateral movement seat 34, screw structure), left-side water-blocking lateral movement platform 25, left-side leakage temporary storage box 26, left-side pressure sensor, and left-side water level sensor 2, and feeding back working data to the main controller in real time.

[0033] Right-side controller (1 unit): Installed on the side wall of waterproof platform 23 inside the right-side groove 28, with a matching sealed waterproof mounting box (integratedly fixed with right-side waterproof platform 23), symmetrically arranged with the left-side controller. It is responsible for controlling and monitoring the status of the right-side lateral movement assembly (right-side lateral movement seat 34, lead screw structure), right-side water-blocking lateral movement platform 25, right-side leakage temporary storage box 26, right-side pressure sensor, and right-side water level sensor 2, and provides real-time feedback of working data to the main controller.

[0034] The system employs a collaborative mode of centralized control by a main controller and decentralized control by side controllers. Data exchange is achieved through waterproof CAN bus communication, ensuring synchronized commands and inter-state linkage. This not only solves the control inconvenience caused by recessed isolation but also improves the operational stability of the device. Furthermore, the wiring of all components is equipped with a waterproof layer and has sufficient length and a well-planned spatial layout, ensuring that the movement of each component is not hindered.

[0035] The charging method of the wireless intelligent charging device for new energy vehicles according to the present invention includes the following steps: Step 1: Slowly drive the vehicle into the wireless charging area 1, align the vehicle tires with the side flood control platforms 25 on both sides, and ensure that all four tires are stably placed on the surface of the flood control platforms 25. The vehicle is roughly parked in the middle of the wireless charging area 1 (precise alignment is not required). Then, the driver turns off the vehicle engine, gets out of the vehicle, and confirms that the vehicle is in the parked state.

[0036] At this time, the pressure sensor on the surface of the water-blocking transverse platform 25 detects the tire pressure signal and transmits the signal to the controller, which confirms that the vehicle has stopped in place.

[0037] Step two: After receiving the arrival signal from the pressure sensor, the controller activates vision sensor 6. Vision sensor 6 captures and identifies the charging position on the car floor in real time and transmits the position data to the controller. Based on the identification results, the controller synchronously controls the wireless charging component, the stacked longitudinal moving waterproof component, and the stacked lateral moving waterproof component to work together to achieve precise alignment between the wireless charging transmitter 5 and the charging position on the car floor, as detailed below: Lateral alignment (vehicle width direction): After receiving the arrival signal from the pressure sensor, the main controller activates the vision sensor 6. The vision sensor 6 captures and identifies the charging position on the car floor in real time and transmits the position data to the main controller. Based on the identification results, the main controller sends lateral movement commands to the left and right side controllers, synchronously controlling the lateral movement components on both sides to work together to align the vehicle width. The left side controller activates the screw structure on the left waterproof platform 2 33, and the right side controller activates the screw structure on the right waterproof platform 2 33. The two lateral movement seats 34 slide laterally along the waterproof platform 2 33, causing the water-blocking transverse plates 27 and leakage storage tanks 26 at their respective tops to move synchronously. Since the vehicle tires are parked on the two water-blocking transverse platforms 25, the water-blocking transverse platforms 25 move laterally along with the water-blocking transverse plates 27, thereby causing the entire vehicle to move laterally passively until the charging position on the car floor is aligned with the wireless charging transmitter 5 in the vehicle width direction.

[0038] During this process, the water-blocking horizontal movement platform 25 is slidably connected to the hardened plate 24 of the wireless charging area 1 via the horizontal movement groove, the water-blocking horizontal movement plate 27 is slidably connected to the empty groove 29, and the leakage temporary storage box 26 moves synchronously with the water-blocking horizontal movement platform 25. Its design, with a width greater than that of the water-blocking horizontal movement platform 25, effectively prevents rainwater from seeping from the edge of the water-blocking horizontal movement platform 25 into the empty groove 29 and the side groove 28. At the same time, the controller receives feedback signals from the vision sensor 6 in real time and dynamically adjusts the lateral movement distance to ensure alignment accuracy.

[0039] Longitudinal alignment (vehicle length direction): After lateral alignment is completed, the main controller sends a "lock command" to the side controllers on both sides to ensure that the lateral moving components on both sides remain stationary. Then, the screw mechanism on the waterproof platform 16 is activated, causing the longitudinal moving seat 17 to slide longitudinally along the platform 16. The longitudinal moving seat 17, through the lifting element 18, drives the top mounting base 4, wireless charging transmitter 5, and vision sensor 6 to move longitudinally in sync, enabling the wireless charging component to move along the vehicle's length. Simultaneously, the stacked longitudinal moving waterproof components connected to both ends of the wireless charging component move synchronously. The water baffle 7 slides along the groove on the hardened plate 24 via the slider 12 at the bottom. The accordion-style protective cover 8 extends and retracts with the longitudinal movement of the wireless charging component, and the water-blocking plate 9 slides along the side groove within the central groove 13, ensuring that the longitudinal waterproof barrier remains intact during the movement of the wireless charging component, preventing rainwater from seeping into the central groove 13.

[0040] The design of the water baffle 7 extending at both ends accommodates the displacement of the wireless charging component during vertical movement. The symmetrically arranged water baffles 7 are connected as one unit by the water baffle strip 10, further enhancing the vertical water-blocking effect. One end of the accordion-style protective cover 8 is connected to the lifting protective cover 19, and the other end abuts against the end of the extension of the wireless charging area 1. Sufficient length is reserved during the extension and retraction process to prevent the temporary storage cavity 14 from being completely compressed, ensuring that the water inlet 15 is unobstructed.

[0041] Spacing adjustment (height direction): After the longitudinal and lateral alignment is completed, the controller controls the lifting element 18 to start (using a hydraulic cylinder or electric telescopic rod, etc.). The lifting element 18 drives the mounting base 4 and the wireless charging transmitter 5 to rise and fall, adjusting the distance between the wireless charging transmitter 5 and the charging position on the car floor until the optimal wireless charging distance is reached (the optimal distance parameter can be preset), thus completing the overall alignment operation.

[0042] During this process, the lifting protective cover 19 rises and falls together with the mounting base 4. The lifting protective cover 19 is slidably connected with the water baffle 7, the bellows-style protective cover 8, the water blocking plate 9 and the middle groove 13. The waterproof rubber strip 1 22 and the waterproof rubber strip 23 at the contact parts can effectively prevent rainwater from seeping into the middle groove 13 through the gaps, protecting the internal power components. The leakage temporary storage groove 21 in the lifting protective cover 19 can temporarily store a small amount of leaked rainwater, preventing rainwater from seeping into the middle groove 13 after the waterproof adhesive 20 ages.

[0043] Step 3: After alignment, the controller confirms that the wireless charging transmitter 5 is correctly aligned with the charging position of the car floor, that there is no abnormal water accumulation in each waterproof area, and that the spacing meets the requirements. It then automatically starts the wireless charging transmitter 5 to transmit power to the charging coil of the car floor and begin wireless charging. At the same time, the controller monitors the working status of the wireless charging transmitter 5 in real time to ensure that the charging power and voltage are stable.

[0044] Step four: During the charging process, the controller continuously receives feedback signals from various sensors to achieve comprehensive monitoring and protection. Five water level sensors monitor the water level in their respective areas in real time. The water level in the central recess (13, sensor 1), the temporary storage chamber (14, accordion-style protective cover 8, sensor 3), and the leakage storage tank (21, lifting protective cover 19, sensor 4) are directly monitored by the main controller. The water level in the side recesses (28, sensor 2) and the temporary storage chamber (30, leakage storage tank 26, sensor 5) are monitored by the corresponding side controllers. The monitoring data is transmitted to the main controller in real time. When the water level reaches a preset threshold, the main controller immediately issues an emergency power-off command. All three controllers execute this command simultaneously, cutting off the charging power and issuing an alarm to prevent short circuits caused by water immersion in electrical components.

[0045] Pressure monitoring: The pressure sensors of the two side water-blocking transverse platforms 25 are monitored by the corresponding side controllers and the pressure data is fed back to the main controller in real time. If an abnormal pressure is detected (such as vehicle slippage or tires coming off the water-blocking transverse platform 25), the corresponding side controller immediately sends an abnormal signal to the main controller. The main controller issues an instruction to stop charging and lock all moving parts. The three controllers execute synchronously and issue an alarm to avoid equipment damage or charging failure.

[0046] Equipment status monitoring: The main controller monitors the working status of the longitudinal movement component, the lifting component, and the wireless charging component. The two side controllers monitor the working status of their respective lateral movement components. All equipment status data are summarized to the main controller in real time. If jamming or malfunction occurs, the corresponding controller immediately sends a fault signal to the main controller. The main controller issues a pause charging command, and all three controllers execute synchronously and issue an alarm prompt, which facilitates the maintenance of each area by the staff.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
