[0002] Wireless charging equipment for new energy vehicles is a high-power charging device that replenishes the high-voltage power battery of electric vehicles. This device does not rely on charging cables, but achieves non-contact power transmission through electromagnetic induction, electromagnetic resonance, radio frequency and other methods, avoiding safety hazards such as leakage and electric current leakage.

[0003] Most existing wireless charging devices are buried underground, with a small portion located on the ground. The portion located on the ground, lacking any protective devices, is susceptible to damage from being run over by cars or impacted by external objects. Over time, dust accumulates on the surface of the wireless charging devices, potentially reducing their charging performance. Utility Model Content

[0004] The purpose of this utility model is to address the problems of existing wireless charging devices, such as the ground-facing portion being damaged by cars or impacts from foreign objects, and the accumulation of dust on the surface of the wireless charging device after prolonged use, which may degrade the charging effect. Therefore, this utility model proposes a protective device for wireless charging devices for new energy vehicles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective device for wireless charging equipment for new energy vehicles includes a fixed box, a fixed box connected to the top of the fixed box, a second through slot on both sides of the fixed box, and the same wireless charging device is attached to the inner wall of the two second through slots. A protective mechanism is provided inside the fixed box, and two first through slots are provided on one side of the inner wall of the fixed box.

[0007] The protective mechanism includes a threaded sleeve and two support blocks. One end of the threaded sleeve is connected to the bottom of the wireless charging device. One side of the support block is connected to the bottom of the fixed box, and the other side of the support block is connected to the inner wall of the fixed box. A threaded rod is threadedly connected to the inner wall of the threaded sleeve. A gear is connected to one end of the threaded rod. A rack is meshed on both sides of the gear. A connecting plate is connected to the other side of the rack. The outer wall of the connecting plate is slidably connected to the inner wall of the first through groove. A protective plate is connected to one side of the connecting plate. The outer wall of the protective plate is slidably connected to the inner wall of the fixed box.

[0008] As a further description of the above technical solution:

[0009] Furthermore, the two support blocks are connected by the same fixing plate, and a motor is connected to the bottom of the fixing plate. The output shaft of the motor passes through the bottom of the fixing plate and is connected to one side of the gear.

[0010] As a further description of the above technical solution:

[0011] A sealing mechanism is provided on one side of the protective plate. The sealing mechanism includes a groove, which is formed on one side of the protective plate.

[0012] As a further description of the above technical solution:

[0013] An installation plate is slidably connected to the inner wall of the chute, and a sealing strip is connected to one side of the installation plate. The outer wall of the sealing strip is in contact with the inner wall of the chute.

[0014] As a further description of the above technical solution:

[0015] Two sliding rods are connected to one side of the mounting plate. Springs are fitted around the sliding rods, and the two ends of the springs are connected to one side of the mounting plate and the inner wall of the sliding groove, respectively.

[0016] As a further description of the above technical solution:

[0017] Two sliding grooves are provided on one side of the slide rail, and the inner wall of the sliding groove is slidably connected to the outer wall of the slide rod.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by setting up a protective mechanism, the rotation of the motor output shaft drives the gear and threaded rod to rotate, thereby driving the threaded sleeve and wireless charging device to move downward, so that the wireless charging device can be retracted into the fixed box. At the same time, the gear can drive the connecting plates and protective plates on both sides to move towards each other through the racks on both sides, thereby blocking the second through slot and preventing the wireless charging device from being run over by a car or damaged by an impact from a foreign object, thus improving the service life of the wireless charging device.

[0020] 2. In this utility model, by setting a sealing mechanism, when the protective plates on both sides are closed, the two sealing strips will be squeezed against each other, causing the mounting plate and slide rod to move and the spring to be compressed, so that the spring generates elastic force. The elastic force of the spring can make the two sealing strips fit tightly together, thereby improving the sealing effect of the sealing strips and preventing dust from entering the fixed box from the gap between the two protective plates. This keeps the wireless charging device clean and improves the charging effect of the wireless charging device. After prolonged use, the sealing strips will undergo irreversible deformation, causing gaps to appear between the two sealing strips. The spring can use its elastic force to make the two sealing strips fit tightly together, allowing the sealing strips to continue to be used, thereby improving the service life of the sealing strips.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model provides a technical solution: a protective device for wireless charging equipment of new energy vehicles, including a fixed box 3, a fixed box 2 connected to the top of the fixed box 3, a second through groove 7 on both sides of the fixed box 2, and the same wireless charging device 1 is attached to the inner wall of the two second through grooves 7, a protective mechanism 4 is provided inside the fixed box 3, and two first through grooves 6 are opened on one side of the inner wall of the fixed box 2.

[0029] The protective mechanism 4 includes a threaded sleeve 401 and two support blocks 405. One end of the threaded sleeve 401 is connected to the bottom of the wireless charging device 1. One side of the support block 405 is connected to the bottom of the fixed box 2, and the other side of the support block 405 is connected to the inner wall of the fixed box 3. A threaded rod 409 is threadedly connected to the inner wall of the threaded sleeve 401. One end of the threaded rod 409 is connected to a gear 402. Both sides of the gear 402 are meshed with racks 406. The other side of the racks 406 is connected to a connecting plate 407. The outer wall of the connecting plate 407 is slidably connected to the inner wall of the first through groove 6. A protective plate 408 is connected to one side of the connecting plate 407. The outer wall of the protective plate 408 is slidably connected to the inner wall of the fixed box 2. The two support blocks 405 are connected to the same fixed plate 404. A motor 403 is connected to the bottom of the fixed plate 404. The output shaft of the motor 403 passes through the bottom of the fixed plate 404 and is connected to one side of the gear 402.

[0030] The specific implementation method is as follows: By setting up a protective mechanism 4, the output shaft of the motor 403 rotates to drive the gear 402 to rotate, and the rotation of the gear 402 drives the threaded rod 409 to rotate. Since the threaded sleeve 401 is threaded, when the threaded rod 409 rotates in the threaded sleeve 401, it can drive the threaded sleeve 401 to move downward. The downward movement of the threaded sleeve 401 drives the wireless charging device 1 to move downward, so that the wireless charging device 1 can be retracted into the fixed box 3. At the same time, the gear 402 can drive the racks 406 on both sides to move. Since the two racks 406 are symmetrically distributed on both sides of the gear 402, the racks 406 can drive the connecting plates 407 on both sides to move towards each other in the first through groove 6, thereby driving the protective plates 408 on both sides to move towards each other in the fixed box 2, thus blocking the second through groove 7, preventing the wireless charging device 1 from being run over by a car or damaged by an impact from a foreign object, and improving the service life of the wireless charging device 1.

[0031] A sealing mechanism 5 is provided on one side of the protective plate 408. The sealing mechanism 5 includes a slide groove 504, which is opened on one side of the protective plate 408. An installation plate 502 is slidably connected to the inner wall of the slide groove 504. A sealing strip 501 is connected to one side of the installation plate 502. The outer wall of the sealing strip 501 is in contact with the inner wall of the slide groove 504. Two slide rods 505 are connected to one side of the installation plate 502. A spring 503 is sleeved on the slide rod 505. The two ends of the spring 503 are respectively connected to one side of the installation plate 502 and the inner wall of the slide groove 504. Two sliding grooves 506 are opened on one side of the slide groove 504. The inner wall of the sliding groove 506 is slidably connected to the outer wall of the slide rod 505.

[0032] The specific implementation method is as follows: By setting the sealing mechanism 5, when the protective plates 408 on both sides are closed, the two sealing strips 501 will be squeezed against each other and move into the slide groove 504. The movement of the sealing strips 501 drives the mounting plate 502 to move, and the movement of the mounting plate 502 drives the slide rod 505 to move in the slide groove 506. At the same time, the mounting plate 502 can also drive the spring 503 to compress, so that the spring 503 generates elastic force. The elastic force of the spring 503 can make the two sealing strips 501 fit tightly together, thereby improving the sealing effect of the sealing strips 501 and preventing dust from entering the fixed box 3 from the gap between the two protective plates 408. This keeps the wireless charging device 1 clean and improves the charging effect of the wireless charging device 1. When the sealing strips 501 undergo irreversible deformation after prolonged use, a gap will be generated between the two sealing strips 501. At this time, the spring 503 can use its elastic force to make the two sealing strips 501 fit tightly together, so that the sealing strips 501 can continue to be used, thereby improving the service life of the sealing strips 501.

[0033] Working principle: When in use, the motor 403 is started. The output shaft of the motor 403 rotates, driving the gear 402 and the threaded rod 409 to rotate. Since the threaded sleeve 401 has threads, the threaded rod 409 can drive the threaded sleeve 401 to move downward when it rotates inside the threaded sleeve 401. The downward movement of the threaded sleeve 401 drives the wireless charging device 1 to move downward, allowing the wireless charging device 1 to be retracted into the fixed box 3. At the same time, the gear 402 can drive the racks 406 on both sides to move. Since the two racks 406 are symmetrically distributed on both sides of the gear 402, the racks 406 can drive the connecting plates 407 on both sides and the protective plates 408 on both sides to move towards each other, thereby blocking the second through slot 7. To prevent the wireless charging device 1 from being run over by a car or impacted by foreign objects, when the protective plates 408 on both sides are closed, the two sealing strips 501 will be squeezed against each other and move into the slide groove 504. The movement of the sealing strips 501 drives the mounting plate 502 and the slide rod 505 to move, and drives the spring 503 to compress, so that the spring 503 generates elastic force. The elastic force of the spring 503 can make the two sealing strips 501 fit tightly together, preventing dust from entering the fixed box 3 from the gap between the two protective plates 408. And when the sealing strips 501 undergo irreversible deformation after prolonged use, the spring 503 can use its elastic force to make the two sealing strips 501 fit tightly together, so that the sealing strips 501 can continue to be used.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
