The existing wireless charging technology is difficult to solve the technical problem of charging electric vehicles that are not equipped with a wireless power receiving device.

[0009] In addition, since the wireless transceiver controller supplies power to the mobile wireless transceiver through the cable, and the mobile wireless transceiver then transfers the power to the electric vehicle, the charging speed is fast and the mobile wireless transceiver is guaranteed to have sufficient power, thus avoiding the problem of insufficient power in the mobile wireless transceiver during the power supply process and ensuring that the mobile wireless transceiver can charge the electric vehicle to the ideal power in one charge.

[0012] Optionally, the control component includes a left wire pulley and a right wire pulley rotatably disposed in the cable storage box, a channel for the cable to pass through is formed between the left wire pulley and the right wire pulley, and the left wire pulley and the right wire pulley are both in contact with the cable.

[0013] By adopting the above technical solution, the cable is located in the cable storage box and passes through and out through the channel between the left wire pulley and the right wire pulley.

The wireless transceiver 6 is then connected to the wireless transceiver equipment 24; thereafter, the wireless transceiver controller 1 supplies power to the wireless transceiver through the cable 5, and after the power passes through the mobile wireless transceiver 6, the wireless transceiver equipment 24 and the charging gun 22 in turn, the power is passed into the electric car 3 to charge the electric car 3; thereafter, the mobile wireless transceiver 6 communicates with the wireless charging and discharging gun 21, and the mobile wireless transceiver 6 obtains the power information of the electric car 3; when the mobile wireless transceiver 6 obtains the charging completion information of the electric car 3, the mobile wireless transceiver 6 is disconnected from the wireless transceiver equipment 24, and the mobile wireless transceiver 6 drives the cable 5 to return to the initial position.

[0050] In summary, when the electric car 3 itself is not equipped with a wireless power receiving device, a wireless charging and discharging gun 21 can be obtained, and the charging gun 22 can be inserted into the charging interface of the electric car 3, so that the mobile wireless transceiver 6 can automatically find the electric car 3, thereby charging the electric car 3 that is not equipped with a wireless power receiving device. The existing wireless charging technology is difficult to solve the technical problem of charging the electric car 3 that is not equipped with a wireless power receiving device.

[0051] This application creatively designs a technical solution of "wireless charging and discharging gun 21", which solves the technical problem of fully automatic wireless charging for the majority of new energy vehicle owners. With the help of the wireless transceiver equipment 24 of the "wireless gun" and the "power bank", new energy vehicles can make an appointment for door-to-door automatic wireless charging, which completely solves the problem of difficulty in charging electric vehicles 3.

[0052] The mobile wireless transceiver device 6 of the present application solves the problem of bidirectional double-sided charging and discharging, so that the intelligent mobile charging equipment can not only charge the fixed wireless charging receiving end, but also charge and discharge the "wireless gun" equipment, meeting the needs of various users.

[0053] The mobile flippable transceiver of the present application can not only charge a fixed wireless charging receiving end, but also flip the wireless charging and discharging plate over to charge and discharge the "wireless gun" equipment.

[0054] The double storage box for the first and second cables 5 of the present application can ensure that the stored cables 5 will not be stuck under the wheels of the vehicle, and at the same time can store longer cables 5 than a single storage box, ensuring that the mobile wireless transceiver 6 can serve a larger parking range across multiple parking spaces and serve more electric vehicles 3 parked near the parking spaces.

[0055] Wireless charging big data analysis and artificial intelligence AI algorithm software regularly analyze users' battery performance and power usage characteristics, providing each user with intelligent and fully automatic wireless charging services.

[0056] The intelligent charging service based on the wireless charging artificial intelligence AI algorithm provided by this application has opened up a new situation in the wireless intelligent charging market, completely solving all the pain points of "difficult charging" of electric vehicles 3, and solving the "charging anxiety" and "range anxiety" of electric vehicle 3 users.

[0057] Example 2 The difference between Example 2 and Example 1 is that: Figure 7 and Figure 8 A first receiving groove 27 and a second receiving groove 28 are provided at the bottom of the lifting bracket 12. The lawn mower 14 includes a mowing blade 29 rotatably arranged in the first receiving groove 27. A mowing motor 30 is installed in the first receiving groove 27. A driving ring 31 is coaxially fixedly connected to the output shaft of the mowing motor 30. The driving ring 31 is fixed with multiple mowing blades 29 at intervals along the circumferential direction.

[0058] The second receiving groove 28 is located at the rear side of the first receiving groove 27 . A grass scraping box 32 is slidably disposed in the second receiving groove 28 . A grass scraping box 32 is provided with a grass inlet 33 communicating with the outside on a side facing the mowing blade 29 .

[0059] A plurality of vertically arranged push springs 34 are arranged at the bottom of the movable bracket, one end of the push spring 34 is fixed to the movable bracket, and the other end is fixed to the grass scraping box 32. Through the arrangement of the push spring 34, the grass scraping box 32 always has a tendency to move in a direction close to the ground.

[0060] An arc hook plate 35 connected to the bottom plate of the grass scraping box 32 is arranged at the grass inlet 33, and a ball 36 for contacting the ground is arranged at the bottom of the arc hook plate 35.

[0061] The implementation principle of Example 2 is as follows: the movement of the mobile wireless transceiver 6 drives the mowing blade 29 and the scraper box 32 to move, and the mowing blade 29 rotates while following the movement of the mobile wireless transceiver 6, thereby realizing the cutting of greening grass plants. When the scraper box 32 follows the mobile wireless transceiver 6 to move to the position of the greening grass plants to be cut, the cut greening grass plants enter the scraper box 32 through the grass inlet 33, and the cut greening grass plants are collected by the scraper box 32; during the movement of the scraper box 32, under the action of the push spring 34, the ball 36 contacts the ground and rolls, so that the movement of the scraper box 32 is more flexible and smooth, and avoids large dry friction between the bottom of the scraper box 32 and the ground, thereby causing wear of the scraper box 32 and reducing the service life of the scraper box 32. When there is an obstacle on the ground during the movement of the scraper box 32, the arc hook plate 35 first contacts the obstacle and can smoothly pass over the obstacle, thereby allowing the scraper box 32 to pass over the obstacle more smoothly, thereby avoiding collision between the scraper box 32 and the obstacle; when the scraper box 32 passes over the obstacle, the push spring 34 is compressed, and after the scraper box 32 passes over the obstacle, the ball 36 will continue to contact the ground under the action of the push spring 34 rebounding.

[0062] Example 3 Embodiment 3 of the present application discloses a wireless gun transceiver method for automatically wirelessly charging an electric vehicle, using a wireless gun transceiver device for automatically wirelessly charging an electric vehicle in Embodiment 1. The wireless gun transceiver method is applicable to an electric vehicle 3 that is not equipped with a wireless charging device, and specifically includes the following steps: S1: The user registers the vehicle information on the wireless charging SAAS background through the mobile phone APP. When using it for the first time, it is necessary to provide the license plate number, address, phone number and other information of the vehicle to be charged. When the electric car 3 of the "wireless gun" user needs to be charged, the user can purchase the "wireless gun" charging service on the mobile phone APP, or rent the charging service by paying a deposit. Each user account can register multiple electric car 3 license plates and purchase or rent multiple "wireless gun" equipment; After purchase, you only need to insert the charging gun 22 on the wireless charging gun 21 into the charging gun 22 socket of the electric car 3. After insertion, the indicator light on the wireless charging gun 21 starts to flash, and the wireless charging gun 21 automatically detects and obtains the current location information of the vehicle, automatically contacts the wireless charging SAAS background and verifies whether the vehicle is within the range of the wireless charging service area 2 of the parking lot. If it is within the range of the wireless charging service area 2, the wireless charging SAAS background notifies the wireless transceiver controller 1, and the location information of the electric car 3 is transmitted to the mobile wireless transceiver device 6 through the background; S2: The user's mobile phone APP or client applet shows that the scheduled charging is successful, and the wireless transceiver controller 1 supplies power to the mobile wireless transceiver device 6 through the cable 5; After the scheduled charging process is started, the mobile wireless transceiver 6 first starts the running wheels 11 and the first cable collection box 4 and the second cable collection box 15 according to the vehicle position and parking space information provided by the wireless charging SAAS background. After the mobile wireless transceiver 6 finds the vehicle and the wireless charging and discharging gun 21, under the guidance of the ultrasonic probe, the camera 9 is used to scan the positioning QR code 25 on the wireless charging and discharging gun 21 to obtain information, and then the double-sided transmitting and receiving plate 7 is aligned with the wireless transceiver equipment 24 on the wireless charging and discharging gun 21, and the charging process is started to start wireless charging; S3: During the wireless charging process, the mobile wireless transceiver 6 communicates with the wireless charging and discharging gun 21 through the double-sided transmitting and receiving board 7, and both parties enter the wireless charging process; S4: After the wireless charging is completed, the mobile wireless transceiver 6 starts the running wheels 11 and the first cable retracting box 4 and the second cable retracting box 15 again, retracts the cable 5 according to the original return process, and returns to the initial position.

[0063] In step S4, after the wireless charging is completed, the second cable wire collection box 15 starts to collect the cable wire 5 first, following the same route and opposite direction of the cable wire 5, until the cable wire 5 reaches the first turn starting from the first cable wire collection box 4. After the turn, the second cable wire collection box 15 stops collecting the cable wire 5, and the first cable wire collection box 4 is responsible for continuing to collect the cable wire 5. The collecting and releasing speed of the cable wire 5 is the same as the driving speed of the mobile wireless transceiver 6, until all the released cables 5 are collected and reach the initial position, ensuring that the cable wire 5 will not be stuck under the wheels of the vehicle. During the process of paying out or collecting the cables, if the camera 9 or other sensors detect that the vehicle is moving, the lifting bracket 12 of the mobile wireless transceiver 6 immediately descends and enters the pressure-resistant mode, and sends the vehicle movement information to the wireless charging SAAS background. The wireless charging SAAS background forwards the vehicle movement information to the user, and continues the paying out or collecting operation after receiving the user's reply confirming that the vehicle has left or is no longer moving.

[0064] It should be explained that in this embodiment, when the wireless charging and discharging gun 21 is in the state shown in the figure, it corresponds to the mobile wireless transceiver 6 with a flippable double-sided transmitting and receiving plate 7. The specific matching steps are roughly the same as the above steps. The difference is that in S2, when the mobile wireless transceiver 6 finds the location of the vehicle and the wireless charging and discharging gun 21 according to the vehicle location and parking space information provided by the wireless charging SAAS background, the flip control motor controls the double-sided transmitting and receiving plate 7 to flip, and then the lifting bracket 12 is raised so that the camera 9 can scan the positioning QR code 25 on the wireless charging and discharging gun 21 to obtain information, and then the double-sided transmitting and receiving plate 7 is aligned with the wireless transmitting and receiving equipment 24 on the wireless charging and discharging gun 21, and the charging process is started to start wireless charging.

[0065] The wireless transceiver controller 1 and the first cable retracting box 4 in the embodiment of the present application can be installed on a mobile charging robot 26, and the wireless transceiver controller 1 and the first cable retracting box 4 are driven to move by the mobile charging robot 26. The wireless transceiver controller 1 can also be directly fixed on the wall, or fixedly installed on a bracket on the ground.

[0066] Example 4 The difference between Example 4 and Example 1 is that: Fig. 9 A wireless charging device is fixedly installed at the bottom of the electric vehicle 3. The fixed wireless charging device 16 includes a wireless charging transceiver board, a charging control unit, an intelligent control unit, a wireless communication unit and a wireless positioning unit.

[0067] Among them, the wireless positioning unit is selected as the Beidou GPS positioning unit.

[0068] The implementation principle of Example 4 is as follows: the fixed wireless charging device 16 can be installed and fixed on the bottom of the electric vehicle 3. When the electric vehicle 3 equipped with the fixed wireless charging device 16 is parked in the parking space, the fixed wireless charging device 16 obtains the location information of the electric vehicle 3 through the wireless positioning unit, and the wireless communication unit transmits the location information of the electric vehicle 3 to the background, and the background transmits the location information of the electric vehicle 3 to the mobile wireless transceiver 6; the mobile wireless transceiver 6 receives the location information of the electric vehicle 3, and the mobile wireless transceiver 6 moves to the position of the electric vehicle 3 and communicates with the wireless transceiver through the wireless charging transceiver board. The equipment 24 is electrically connected, the wireless transceiver controller 1 supplies power to the mobile wireless transceiver 6 through the cable 5, the mobile wireless transceiver 6 supplies power to the wireless charging transceiver board through the cable 5, and the power is charged into the electric vehicle 3 through the wireless charging transceiver board; in this process, the mobile wireless transceiver 6 communicates with the wireless charging transceiver board, and the mobile wireless transceiver 6 obtains the power information of the electric vehicle 3; when the mobile wireless transceiver 6 obtains the charging completion information of the electric vehicle 3, the mobile wireless transceiver 6 is disconnected from the wireless charging transceiver board, and the mobile wireless transceiver 6 drives the cable 5 to return to the initial position.

The wireless gun transceiver method is applicable to an electric vehicle 3 with a wireless charging device installed and fixed thereon, and comprises the following steps: S1: The user registers the vehicle information on the wireless charging SAAS background through the mobile phone APP. When using it for the first time, the user needs to provide the license plate number, address, telephone number and other information of the vehicle to be charged. The wireless charging SAAS background checks the fixed installation position information of the fixed wireless charging device 16 of the vehicle to be charged on the vehicle chassis from the car manufacturer or vehicle registration department based on the relevant vehicle information provided by the user and saves it to the wireless charging SAAS background database. When the vehicle needs to be charged, an appointment can be made on the mobile phone APP to inform the wireless charging SAAS background of the license plate number of the vehicle to be charged (multiple selections can be made during registration) and the current parking space number (if any); The wireless charging SAAS backend verifies whether the user is in the wireless charging service area 2 in the parking lot based on the vehicle information. If the user is in the wireless charging service area 2, the reservation charging process is started; if the user's vehicle is not in the wireless charging service area 2, the user is reminded to charge in the nearest wireless charging service area 2; S2: After the scheduled charging process is started, the mobile wireless transceiver 6 finds the fixed wireless charging device 16, and the wireless charging SAAS background notifies the wireless transceiver controller 1 closest to the user's electric car 3 to control the mobile wireless transceiver 6 to move. When the vehicle to be charged stops at the parking space covered by the mobile wireless transceiver 6, according to the vehicle position and parking space information provided by the wireless charging SAAS background, and the relative installation position information of the fixed wireless charging device 16 of the vehicle on the vehicle chassis, the mobile wireless transceiver 6 walks to the side of the vehicle and lowers the height of the lifting bracket 12, so that the mobile wireless transceiver 6 can progress to the bottom of the car, and starts the walking wheel 11 and the first cable collection box 4 and the second cable collection box 15, so that the mobile wireless transceiver 6 moves under the car chassis, and finds the fixed wireless charging device 16 of the vehicle and adjusts the height of the lifting bracket 12 to align with it according to the positioning information sent by the fixed wireless charging device 16 or the positioning information set under the car chassis, and starts the charging process for wireless charging; S3: The mobile wireless transceiver 6 starts the wireless charging process and communicates with the fixed wireless charging device 16 of the vehicle, and both parties enter the wireless charging process; S4: After the wireless charging is completed, the mobile wireless transceiver 6 adjusts the height of the lifting bracket 12 downward, starts the walking wheel 11 and the first cable collection box 4 and the second cable collection box 15 to move out from under the car chassis, and then retracts the cable 5 according to the original return process and returns to the initial position.

[0070] In step S2, when the mobile wireless transceiver 6 moves, the first cable retracting box 4 is responsible for the retracting and releasing of the cable 5 of the mobile wireless transceiver 6 in the parking space or before turning; when the mobile wireless transceiver 6 needs to turn again, the first cable retracting box 4 stops releasing the cable, and then the second cable retracting box 15 is responsible for continuing to retract and release the cable 5, and the retracting and releasing speed of the cable 5 is the same as the driving speed of the mobile wireless transceiver 6 until it reaches the target position.

[0071] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
