[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example 1, by Figures 1-8 The present invention relates to a wireless charging device for electric vehicles, comprising a base frame 1 and an electric vehicle body 7. The base frame 1 has a through hole 6 in the middle of its top. The electric vehicle body 7 is located on the top of the base frame 1. A wireless charging receiver 5 located directly above the through hole 6 is fixedly connected to the bottom of the electric vehicle body 7. Two receiving slots 9 are symmetrically arranged on the top of the base frame 1. An infrared sensor 8 is installed in each of the two receiving slots 9. An adjustment mechanism 2 is provided inside the base frame 1. The adjustment mechanism 2 is provided with a dustproof mechanism 3 and a blowing mechanism 4. When the electric vehicle body 7 is driving on the top of the base frame 1, such that the wheels of the electric vehicle body 7 are located on the two receiving slots 9, the infrared sensor 8 can sense the position of the electric vehicle body 7.

[0021] In Embodiment Two, based on Embodiment One, the adjusting mechanism 2 includes a U-shaped frame 201 fixed inside the base frame 1. Two inner rods 202 are symmetrically fixedly connected to the inner side of the U-shaped frame 201. A movable frame 207 is movably sleeved between the two inner rods 202. Three U-shaped round rods 2017 are fixedly sleeved at equal intervals on the movable frame 207. Lifting plates 208, 204, and 3019 are movably sleeved sequentially from left to right on the outer sides of the three U-shaped round rods 2017. The top of the second lowering plate 208 is fixedly connected to the second connecting post 2013, and the top of the second connecting post 2013 is fixedly connected to the wireless charging transmitter 2014. The top of the first lifting plate 204 is fixedly connected to the first connecting post 203, the top of the first connecting post 203 is fixedly connected to the first sealing plate 2016, and the top of the first sealing plate 2016 is fixedly connected to the first sealing ring 2015. The top of the third lifting plate 2019 is equipped with a brush 2018, and the top of the third lifting plate 2019 is fixedly installed with... A rotary motor 2020 has a rotating shaft 2022 fixedly connected to it. A top plate 2021 is fixedly connected to the top of the rotating shaft 2022. A brush 2018 is fixed to the top of the top plate 2021. A drive motor 2011 is fixedly installed on the inner side of a U-shaped frame 201. A screw 2012 is fixedly connected to the drive motor 2011. The end of the screw 2012 away from the drive motor 2011 is rotatably connected to the U-shaped frame 201. A movable frame 207 is movably sleeved on the screw 2012. On the outside of 012, two support columns 2010 are symmetrically fixedly connected between the bottom of the U-shaped frame 201 and the inner bottom wall of the base frame 1. A base plate 209 is movably sleeved between the two support columns 2010. Two L-shaped round rods 206 are symmetrically fixedly connected to the outside of the base plate 209. The tops of the two L-shaped round rods 206 are located below the lifting plate 204. An electric push rod 205 is fixedly installed on the inner bottom wall of the base frame 1. The bottom of the base plate 209 is fixed to the output end of the electric push rod 205. When the drive motor 2011 is started, it drives the screw 2012 to rotate and causes the movable frame 207 to slide along the two inner rods 202, thereby realizing the horizontal movement of the wireless charging transmitter 2014, the sealing disc 1 2016 and the brush 2018. When the electric push rod 205 is activated, it drives the base plate 209 to slide upward along the two support columns 2010, thereby raising the two L-shaped round rods 206. When the movable frame 207 moves the lifting plate 204 above the two L-shaped rods 206, the electric push rod 205 drives the two L-shaped rods 206 to rise and push the lifting plate 204. The connecting column 203 drives the sealing plate 2016 to move upward until the sealing ring 2015 is in contact with the inner top wall of the bottom frame 1, thereby sealing the through hole 6 and preventing people or objects from falling. When the movable frame 207 moves the lifting plate 2019 above the two L-shaped rods 206, the electric push rod 205 drives the two L-shaped rods 206 to rise and push the lifting plate 2019, causing the top plate 2021 to rise and pass through the through hole 6 until the brush 2018 contacts the wireless charging receiver 5. Then the rotary motor 2020 can be started to drive the rotating shaft 2022 to rotate, and drive the top plate 2021 and brush 2018 to rotate, thereby cleaning the wireless charging receiver 5. When the movable frame 207 moves the lifting plate 208 above the two L-shaped rods 206, the electric push rod 205 drives the two L-shaped rods 206 to rise and push the lifting plate 208. The connecting column 2013 drives the wireless charging transmitter 2014 to rise, so that the wireless charging transmitter 2014 passes through the through hole 6 until it is in contact with the wireless charging receiver 5, and finally realizes the fast wireless charging of the electric vehicle body 7.

[0022] In Example 3, based on Example 1, the dustproof mechanism 3 includes a sealing disc 2 301 located above the lifting plate 3 2019. A sealing telescopic cover 303 is fixedly connected between the sealing disc 2 301 and the lifting plate 3 2019. A rotary motor 2020 is located inside the sealing telescopic cover 303. A rotating shaft 2022 passes through the sealing disc 2 301. A sealing ring 2 302 is fixedly connected to the top of the sealing disc 2 301. Two guide rods 306 are symmetrically fixedly connected to the bottom of the sealing disc 2 301. A guide cylinder 304 is movably sleeved on the outer side of each of the two guide rods 306. The bottom ends of the two guide cylinders 304 are fixed to the top of the lifting plate 3 2019. A spring 305 is fixedly connected between the two guide cylinders 304 and the sealing disc 2 301. The two springs 305 are respectively sleeved on the outer side of the two guide rods 306. When the lifting plate 3 2019 slides upward along the corresponding U-shaped rod 2017, it drives the sealing plate 2 301 and the brush 2018 to rise, so that the brush 2018 extends out of the outside of the bottom frame 1 from the through hole 6. When the sealing ring 2 302 contacts the inner top wall of the bottom frame 1, the brush 2018 does not contact the wireless charging receiver 5 at this time. Then the lifting plate 3 2019 continues to rise until the brush 2018 contacts the wireless charging receiver 5. During this process, the distance between the sealing plate 2 301 and the lifting plate 3 2019 changes. The two guide rods 306 slide along the two guide cylinders 304 respectively, and the two springs 305 are deformed, so that the sealing ring 2 302 is tightly attached to the bottom frame 1 under the action of the elastic force of the two springs 305, thus sealing the through hole 6. Finally, it prevents the dust that falls during the cleaning of the wireless charging receiver 5 from entering the bottom frame 1 through the through hole 6.

[0023] In Example 4, based on Example 1, the purging mechanism 4 includes a bellows 401 fixed to the top of the sealing plate 2 301, a rotating shaft 2022 passing through the bellows 401, a filter screen 402 installed on the bellows 401, and multiple blades 406, all located inside the bellows 401, fixedly connected at equal angles to the outer side of the rotating shaft 2022. Connecting pipes 405 are fixedly connected to both sides of the bellows 401, and an arc-shaped pipe 403 located at the top of the top plate 2021 is fixedly connected to the end of each of the two connecting pipes 405 away from the bellows 401. Multiple exhaust ports 404 are provided on the outer side of each of the two arc-shaped pipes 403. By setting the filter screen 402, it is convenient to filter the gas entering the bellows 401. The filter screen 402 is fixed to the bellows 401 by bolts, which is convenient for disassembling and cleaning the filter screen 402. When the shaft 2022 rotates, it drives the blades 406 to rotate, causing outside air to enter the air box 401 after being filtered by the filter screen 402. Then, the air enters the two arc-shaped pipes 403 through the two connecting pipes 405 and is discharged from each exhaust port 404, blowing away the bottom of the wireless charging receiver 5 and removing the dust that has fallen on the brush 2018 and the top plate 2021, thus improving the cleaning effect of the wireless charging receiver 5.
