Description

Technical Field

[0001] The present invention relates to the technical field of wireless charging, and in particular to a wireless charging device with adjustable vehicle position for parking spaces. 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 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 of the vehicle chassis There are differences in the positions. 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, thereby 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 entry, there is still a position correspondence deviation for the fixed wireless charging head, which requires the driver to adjust, resulting in a poor driver experience. 3) For drivers with poor driving skills, it is easy for the center axis of the vehicle to be far away from the center axis of the parking space when parking. In this case, in order to ensure better charging, the driver needs to adjust the vehicle frequently, which results in more parking time, a more cumbersome process, and a poor experience. Therefore, it is urgent to design a wireless charging device with adjustable vehicle position for parking spaces. Summary of the invention

[0035] Combined with Figure 1-7As shown, the movable plate 2 moves along the direction consistent with the length direction of the vehicle on the parking space under the action of the corresponding movable plate driving mechanism, and the four movable plates 2 are each provided with a lower groove 5, and a pressure sensor 9 is arranged in the lower groove 5. Specifically, the pressure sensor 9 is arranged on the bottom groove wall of the lower groove 5, and the pressure sensor 9 is provided with a plurality of rollers 6 for carrying the wheels of the vehicle on the parking space. The central controller 8 is electrically connected to the movable plate driving mechanism and the pressure sensor 9. Specifically, the lower groove 5 is opened on the corresponding movable plate 2 along the direction consistent with the width direction of the vehicle on the parking space. Preferably, the lower groove 5 is a rectangle when viewed from top to bottom, and the straight line where the long side of the rectangle is located is parallel to the parking space. The width direction of the vehicles on the parking space is consistent, and the length of the lower groove 5 is long enough to meet the parking needs of vehicles of different widths. Preferably, the length value of the lower groove 5 is one-quarter of the width of the parking space to two-fifths of the width of the parking space, and the lower groove 5 is a downwardly concave V-shaped structure. Specifically, the side sectional view of the lower groove 5 is a V-shaped structure with the tip facing downward. A plurality of rollers 6 are arranged in an arranged manner on the corresponding pressure sensor 9, and the extension direction of the projection of the axis of the roller 6 on the horizontal plane is consistent with the length direction of the vehicle located in the parking space. A load-bearing bin 10 is provided at the position of the opening 1, and the load-bearing bin 10 extends to the bottom of the parking space. The opening 1 is connected to the inside of the load-bearing bin 10, and the movable plate driving mechanism It is arranged in the bearing bin 10, and the mobile plate driving mechanism includes a mobile plate driving cylinder 11, and the mobile plate driving cylinder 11 is arranged in the bearing bin 10. The output end of the mobile plate driving cylinder 11 is connected with a mobile plate driving push rod 12, and the mobile plate driving push rod 12 is connected to the mobile plate 2. The mobile plate driving cylinder 11 is electrically connected to the central controller 8. A plurality of rollers 13 are arranged at the bottom of the mobile plate 2, and a plurality of the rollers 13 are fitted with the bottom bin wall of the bearing bin 10 corresponding to the corresponding mobile plate 2. In the initial state, the lower groove 5 on the mobile plate 2 is located at the farthest position away from the center of the parking space. For example, after a vehicle enters the parking space, one of the wheels of the vehicle enters the corresponding lower groove 5. When the vehicle enters the parking space, one of the wheels of the vehicle enters one of the moving When the movable plate 2 is in the lower groove 5 of the plate 2, for example, the vehicle enters the parking space in a forward manner, one of the front wheels of the vehicle enters the lower groove 5 at the corresponding position and is carried by the corresponding roller 6 and maintained for a period of time, preferably, the holding time is 10s-30s. At this time, the pressure sensor 9 located below the roller 6 in the lower groove 5 carrying the wheel continues to obtain the pressure signal and transmits the pressure signal to the central controller 8. At this time, the movable plate 2 is in a stationary state, and the remaining movable plates 2 begin to adjust their positions. The specific adjustment method is to transmit a single plate control signal to the movable plate drive cylinder 11 corresponding to the corresponding movable plate 2 through the central controller 8, and then the corresponding movable plate drive cylinder 11 pushes the corresponding movable plate 2, thereby adjusting the position of the corresponding movable plate 2.Since the upper and lower grooves 5 of the movable plate 2 are located at the farthest position away from the center of the parking space in the initial state, the remaining movable plates 2 drive the corresponding lower grooves 5 to move in the direction close to the center of the parking space until all the wheels move into the corresponding lower grooves 5. After the rollers 6 in the lower grooves 5 corresponding to the remaining movable plates 2 carry the remaining wheels, the corresponding pressure sensors 9 obtain the pressure signal and transmit the pressure signal to the central controller 8. At this time, the corresponding movable plate driving cylinder 11 stops working, and the corresponding movable plate 2 is in a stationary state. The vehicle wheels are all in the lower grooves 5 and are carried by the corresponding rollers 6. At this time, all pressure sensors 9 obtain the pressure signal and transmit the pressure signal to the central controller 8, and the four movable plates 2 are all in a stationary state. Similarly, when two or three wheels of the vehicle enter the corresponding lower grooves 5, the mobile plates 2 corresponding to the remaining wheels are also adjusted in position until the lower grooves 5 corresponding to the four mobile plates 2 are all moved to the bottom of the four wheels. When the four wheels of the vehicle are in the lower grooves 5 corresponding to the four mobile plates 2 after entering the parking space, all pressure sensors 9 obtain pressure signals and transmit the pressure signals to the central controller 8. At this time, the four mobile plates 2 are all in a stationary state. By setting the rollers 13 to cooperate with the bearing compartment 10, the weight of the vehicle can be ensured when the vehicle is in the lower grooves 5. Regarding the setting of the pressure size that the pressure sensor 9 bears when obtaining the pressure signal, preferably, when the pressure sensor 9 bears a weight of 80KG-300KG, it is used as a node for obtaining the pressure signal, so as to avoid the corresponding mobile plate 2 from erroneously working when the non-vehicle is located on the roller 6. ,

[0036] Combined with Figure 1-7As shown, a vehicle translation adjustment mechanism is provided at the position of the lower groove 5, and the vehicle translation adjustment mechanism is used to apply a force to the wheel carried by the roller 6 in a direction consistent with the vehicle width direction. Specifically, a vertical plate 7 is provided on the movable plate 2 at the side corresponding to the lower groove 5. Preferably, the vertical plate 7 is located on the side of the lower groove 5 away from the symmetry axis of the parking space width, and the vertical plates 7 located on both sides of the symmetry axis of the parking space width are symmetrically arranged compared to the symmetry axis of the parking space width. The vehicle translation adjustment mechanism includes a vehicle translation adjustment cylinder 14, and the vehicle translation adjustment cylinder 14 is provided on the vertical plate 7. The output end of the vehicle translation adjustment cylinder 14 is connected to a vehicle translation adjustment push rod 15. The output direction of the vehicle translation adjustment cylinder 14 is consistent with the vehicle width on the parking space. The directions of the degrees are consistent, the end of the vehicle translation adjustment push rod 15 is connected to the vehicle translation adjustment plate 16, the vehicle translation adjustment cylinder 14 is electrically connected to the central controller 8, and a camera 25 is also arranged on the parking space, the camera 25 is electrically connected to the central controller 8, the camera 25 is located near the wide side of the parking space, and is located on the symmetric axis of the wide side of the parking space, the camera 25 is used to judge whether the vehicle is centered after entering the parking space, when the four wheels of the vehicle are all located in the lower groove 5, the four pressure sensors 9 all obtain the pressure signal and transmit it to the central controller 8, then the central controller 8 transmits the signal to the thermal imaging detector 4 and the camera 25, the camera 25 judges whether the position of the vehicle is centered, and adjusts the position to the center, left or right The information is transmitted to the central controller 8, and the thermal imaging detector 4 performs thermal imaging of the vehicle chassis to obtain the battery position, thereby obtaining the corresponding position of the wireless charging receiving module, and then the battery position is transmitted to the central controller 8. The central controller 8 transmits the vehicle adjustment signal to the mobile plate driving cylinder 11 and the vehicle translation adjustment cylinder 14 according to the battery position. The mobile plate driving cylinder 11 adjusts the corresponding mobile plates 2, and the four mobile plates 2 move synchronously, so that the vehicle is adjusted relative to the front and rear of the parking space. According to the judgment of whether the vehicle is centered by the camera 25, when the vehicle is centered, the vehicle translation adjustment cylinders 14 on the left and right sides of the parking space do not need to push the vehicle wheels. When the vehicle is to the left, the vehicle translation adjustment cylinder 14 on the left side of the parking space The wheel on the same side is pushed to move the vehicle toward the middle of the parking space so that the vehicle can adjust its position relative to the left and right of the parking space. When the vehicle is positioned to the right, the vehicle translation adjustment cylinder 14 located on the right side of the parking space pushes the wheel on the same side to move the vehicle toward the middle of the parking space so that the vehicle can adjust its position relative to the left and right of the parking space. By adjusting the position of the vehicle relative to the front, back, left and right of the parking space, the vehicle battery moves toward the wireless charging head 3, thereby moving the vehicle wireless charging receiving module above the wireless charging head 3. The charging pile seat 18 is electrically connected to the central controller 8. When the vehicle position adjustment is completed, the central controller 8 transmits a charging signal to the charging pile seat 18, and the charging pile seat 18 starts to transmit power to the wireless charging head 3.So that the wireless charging head 3 cooperates with the vehicle's wireless charging receiving module to replenish the vehicle with electric energy. For the adjustment of the left and right positions of the vehicle relative to the parking space, since the working node of the vehicle translation adjustment cylinder 14 is after the vehicle wheels are all located in the corresponding lower grooves 5, at this time the wheels are all in the lower grooves 5, the vehicle translation adjustment cylinder 14 drives the vehicle translation adjustment plate 16 to move horizontally through the vehicle translation adjustment push rod 15, and cooperates with the roller 6 located under the wheel, so as to adjust the left and right positions of the vehicle relative to the parking space.

[0037] For the case where a non-electric vehicle is parked in a parking space, when the vehicle enters the parking space, the movable plate 2 is also adjusted in position so that the wheels are all located in the corresponding lower grooves 5. Since the thermal imaging detector 4 cannot identify the battery position, the corresponding subsequent vehicle position adjustment and the operation of the charging pile seat 18 are not performed. Alternatively, the camera 25 determines whether it is an electric vehicle or a gasoline vehicle by recognizing the vehicle license plate. A warning device is also provided on the parking space. When the camera 25 recognizes the license plate of a gasoline vehicle, a signal is transmitted to the warning device, and the warning device issues a voice reminder. The surface material of the movable plate 2 Epoxy floor paint is selected. When the vehicle wheels are not all located in the corresponding lower grooves 5, the vehicle is not in a charging state, and the vehicle is not in a braking state. Since the vehicle wheels are not braked, the movable plate 2 can move smoothly. If the vehicle wheels are in a braking state, since the surface material of the movable plate 2 is epoxy floor paint, the friction coefficient between the epoxy floor paint and the wheel rubber is small, so that the movable plate 2 can still be moved in the wheel braking state. When the vehicle wheels are all located in the lower grooves 5, due to the structure of the lower grooves 5 themselves, it can be ensured that the vehicle is in a relatively stationary state.

[0038] Combined with Figure 1-3 As shown, a stand 19 is provided in the setting bin 17, and a blower motor 20 is provided on the stand 19. The output end of the blower motor 20 is connected to a blower shaft 21, and the blower shaft 21 is connected to a blower fan blade 22. The blower motor 20 is electrically connected to the central controller 8. When the charging pile seat 18 starts to supply power, the central controller 8 transmits a signal to the blower motor 20, and the blower motor 20 drives the blower fan blade 22 to rotate through the blower shaft 21. The rotating blower fan blade 22 blows air to the charging pile seat 18, thereby cooling the charging pile seat 18. A plurality of ventilation ports 23 connected to the setting bin 17 are provided on the parking space. The ventilation ports 23 are provided to ensure the airflow in the setting bin 17. A filter screen 24 is detachably installed on the ventilation port 23. Since the filter screen 24 is provided, impurities are prevented from entering the setting bin 17. When there are many impurities on the filter screen 24, the filter screen 24 is replaced.

[0039] Working principle: Take the front, back, left, and right of the vehicle as references for the front, back, left, and right of the parking space. When the vehicle enters the parking space, take the example of the left front wheel of the vehicle first entering the lower groove 5 at the left front of the parking space. At this time, the pressure sensors 9 corresponding to the movable plates 2 located at the right front, left rear, and right rear of the parking space do not obtain pressure signals. The movable plate driving cylinders 11 located at the right front, left rear, and right rear of the parking space drive the corresponding movable plates 2 to move. The movable plate 2 located at the right front of the parking space moves toward the rear of the parking space, and the movable plate 2 located at the left rear of the parking space and the movable plate 2 located at the right rear of the parking space move toward the front of the parking space, until the lower grooves 5 corresponding to the movable plates 2 located at the right front, left rear, and right rear of the parking space move to under the right front, left rear, and right rear wheels respectively. At this time, the four pressure sensors 9 all obtain pressure signals, and the camera 25 determines that the vehicle Whether it is centered, the thermal imaging detector 4 starts to judge the battery position, and then transmits the vehicle battery position information to the central controller 8. The central controller 8 transmits the vehicle adjustment signal to four movable plate driving cylinders 11 and the corresponding four vehicle translation adjustment cylinders 14. The movable plate driving cylinder 11 adjusts the position of the vehicle relative to the front and rear of the parking space through the corresponding movable plate 2. According to the judgment result of whether the vehicle is centered, the vehicle translation adjustment cylinder 14 adjusts the position of the vehicle relative to the left and right of the parking space by applying force to the wheels, so that the battery of the vehicle corresponds to the wireless charging head 3, so that the wireless charging receiving module of the vehicle moves to the top of the wireless charging head 3. When the vehicle position adjustment is completed, the charging pile seat 18 starts to supply power, and the vehicle battery is replenished through the wireless charging head 3 and the wireless charging receiving module of the vehicle.
