[0002] With the decreasing fossil energy and increasingly stringent emission regulations, new energy vehicles such as hybrid vehicles and electric vehicles have received more and more attention. In order to reduce dependence on fossil energy, reduce pollution to the environment, and achieve the goal of energy conservation and emission reduction, my country is vigorously developing electric vehicles. New energy vehicles generally use lithium batteries. For electric vehicles, the most important factors restricting their development are their driving range and their price. The driving range of electric vehicles involves the charging problem of electric vehicles. In order to accelerate the development of electric vehicles, my country has formulated various policies and regulations to promote the construction of electric vehicle charging infrastructure.

[0003] There are different types of charging devices for electric vehicles. Among them, the magnetic charging device is a contactless charging device. A receiving electromagnetic coil is set on the chassis of the electric vehicle. The charging device is located on the ground. An electromagnetic coil responsible for transmission is set in the charging device. A signal is sent to the electric vehicle through the electromagnetic coil responsible for transmission. The electromagnetic coil responsible for receiving on the chassis receives the signal and starts charging the electric vehicle.

At the same time, the inclined upper side of the rain shield will allow the rain to flow down. When the electric vehicle is charging, the wheels will move to the upper side of the two first sliding grooves, and then the two first sliding grooves will start to move downward. Then the two first sliding grooves will drive the sliding blocks to move backward through the transmission mechanism, and then the sliding blocks will drive the rain shield to move, so that the charger will be exposed to charge the electric vehicle. At this time, the electric vehicle will block the rain from falling onto the upper side of the charger.

[0027] (2) In the electric vehicle magnetic charging device, when the wheel of the electric vehicle moves to the upper side of the sliding plate, the sliding plate starts to move downward, and then the spring starts to become compressed, and then the meshing groove drives the meshing first gear to start rotating counterclockwise. After a series of transmissions, the first gear drives the rain shield to move backward, and then the charger is exposed to work. After the electric vehicle completes charging and drives away, the spring starts to reset from the compressed state. According to the above, the rain shield moves backward to block the installation groove. After the electric vehicle moves to the upper side of the charging device, the rain shield can be automatically moved away, and the installation groove can be automatically blocked after the electric vehicle leaves. No manual operation is required, making the charging device more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

The upper side of the plate extends out of the upper side of the external shell 1 through the mounting groove 5, and the upper side of the vertical plate of the sliding block 10 is fixedly connected with a rain shield 9, which is arranged on the upper side of the mounting groove 5. The rain shield 9 is a right-angled triangle. When it starts to rain, rainwater will fall on the upper side of the rain shield 9 instead of falling into the inside of the mounting groove 5, so that the charger 6 will not be damaged. At the same time, the inclined upper side of the rain shield 9 will cause rainwater to flow down. When the tram is charging, the wheels will move to the upper side of the two first sliding grooves 2, and then the two first sliding grooves 2 will start to move downward, and then the two first sliding grooves 2 will drive the sliding block 10 to move to the rear side through the transmission mechanism, and then the sliding block 10 will drive the rain shield 9 to move, and then the charger 6 will be exposed to charge the tram. At this time, the tram will block rainwater from falling on the upper side of the charger 6. In this way, the rain shield 9 can be opened when charging and closed when not charging, so that the charger 6 itself will not be drenched by rainwater, thereby avoiding leakage of the charging device and improving the safety of the charging device.

[0035] The transmission mechanism includes two meshing grooves 11, and the two meshing grooves 11 are respectively opened on the left sides of the two sliding plates 3. The right walls of the two meshing grooves 11 extend out of the right sides of the two sliding plates 3. A transmission rod 12 is rotatably connected to the right wall of the first sliding groove 2 on the right side, and the left end of the transmission rod 12 extends into the interior of the external shell 1 through the meshing groove 11. A connecting groove 8 is opened on the bottom wall of the second sliding groove 7, and the connecting groove 8 is opened on the right side of the mounting groove 5. The left end of the transmission rod 12 rotates and penetrates into the interior of the connecting groove 8. The left end of the transmission rod 12 is rotatably connected to the left wall of the connecting groove 8. The outer surface of the transmission rod 12 located in a part of the inner part of the meshing groove 11 is fixedly sleeved with a first gear 13, and the first gear 13 is meshed and connected with the front side of the meshing groove 11. The outer surface of the transmission rod 12 located in a part of the inner part of the connecting groove 8 is fixedly sleeved with a second gear 14, and the second gear 14 is meshed and connected with the lower side of the sliding block 10. The left wall of the first sliding groove 2 on the left side is similarly rotatably connected with the transmission rod 12. The left and right transmission rods 1 2 connection structure is the same and is arranged in a mirror image. When working, when the tram wheel moves to the upper side of the sliding plate 3, the sliding plate 3 starts to move downward, and then the spring 4 starts to become compressed, and then the meshing groove 11 will drive the meshing connected first gear 13 to start rotating counterclockwise, and the first gear 13 drives the transmission rod 12 to start rotating synchronously, and the transmission rod 12 drives the second gear 14 to start rotating synchronously, and then the second gear 14 drives the meshing connected sliding block 10 to start moving to the rear side, and then the sliding block 10 drives the rain shield 9 to move, and then the charger 6 will be exposed to work. After the tram completes charging and drives away, the spring 4 starts to reset from the compressed state. According to the above, it can be seen that the rain shield 9 moves backward to block the installation groove 5. In this way, the rain shield 9 can be automatically removed after the tram moves to the upper side of the charging device, and the installation groove 5 can be automatically blocked after the tram leaves, without manual operation, making the charging device more convenient to use.

[0036] Working principle: when it starts to rain, rainwater will fall on the upper side of the rain shield 9 instead of falling into the inside of the mounting groove 5, so that the charger 6 will not be damaged. At the same time, the inclined upper side of the rain shield 9 will allow rainwater to flow down. When the tram is charging, the wheels will move to the upper side of the two first sliding grooves 2, and then the two first sliding grooves 2 will start to move downward, and then the two first sliding grooves 2 will drive the sliding block 10 to move toward the rear through the transmission mechanism, and then the sliding block 10 will drive the rain shield 9 to move, and then the charger 6 will be exposed to charge the tram. At this time, the tram will prevent rainwater from falling on the upper side of the charger 6.

[0037] When starting to work, when the tram wheel moves to the upper side of the sliding plate 3, the sliding plate 3 starts to move downward, and then the spring 4 starts to become compressed, and then the meshing groove 11 will drive the meshing connected first gear 13 to start rotating counterclockwise, and the first gear 13 drives the transmission rod 12 to start rotating synchronously, and the transmission rod 12 drives the second gear 14 to start rotating synchronously, and then the second gear 14 drives the meshing connected sliding block 10 to start moving toward the rear side, and then the sliding block 10 drives the rain shield 9 to move, and then the charger 6 will be exposed to work. After the tram completes charging and drives away, the spring 4 starts to reset from the compressed state. According to the above, it can be seen that the rain shield 9 moves toward the rear side to block the mounting groove 5.
