[0002] Mobile charging carts, which provide temporary charging services for various mobile devices, are increasingly widely used in modern society. Whether in public places such as shopping malls, airports, and train stations, or in some specific workplaces, mobile charging carts have solved the problem of insufficient power for mobile devices.

[0003] Most mobile charging carts use a press-and-release mechanism to open or close their charging port protection devices. However, in the event of an accidental impact, the charging port may open unexpectedly, potentially leading to contamination. Furthermore, mobile charging carts are typically used in various environments where dust may be present, making effective protection difficult. This can allow dust to enter the charging port, accumulate on the electrode surface, and affect the conductivity of the charging process. Utility Model Content

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1-7As shown, this utility model provides a charging port protection mechanism for a mobile charging cart, including a charging cart body 1, a limiting protection component, and a square frame plate 2. A rolling cleaning component is installed inside the square frame plate 2. The limiting protection component includes an L-shaped plate 4, with a U-shaped plate 5 slidably connected inside the L-shaped plate 4. A first groove 8 is formed on the outer surface of the L-shaped plate 4, and a slider 20 is slidably connected inside the first groove 8. The outer surface of the slider 20 is fixedly connected to the outer surface of the U-shaped plate 5. A placement plate 6 is slidably inserted into the end of the U-shaped plate 5 away from the L-shaped plate 4. A connecting groove rod 7 is movably connected inside the placement plate 6, and a protective plate 3 is fixedly connected to the outer surface of the connecting groove rod 7. The outer surface of the protective plate 3 corresponds to the opening end of the square frame plate 2. A charging port is provided on the outside of the main body 1 of the car. The charging port is located inside the square plate 2. By setting an L-shaped plate 4, any U-shaped plate 5 can be pulled and the protective plate 3 can be rotated to make the connecting groove bar 7 rotate inside the placement plate 6, thereby opening the square plate 2. This prevents the square plate 2 from opening in case of accidental impact and facilitates the maintenance and replacement of the protective plate 3. A first spring 9 is fixedly connected to the inside of the first slide groove 8. The end of the first spring 9 away from the first slide groove 8 is fixedly connected to the outer surface of the slider 20, so that the U-shaped plate 5 can slide on the L-shaped plate 4 and apply pressure to the first spring 9. The slots on both sides of the connecting groove bar 7 correspond to the outer ends of the U-shaped plate 5, so that the U-shaped plate 5 can slide into the slots on both sides of the connecting groove bar 7 and limit its movement.

[0021] The rolling cleaning assembly includes a dust roller 14, a hand-operated rod 15 rotatably connected to the outer surface of a square frame plate 2, a first gear 16 fixedly connected to the outer end of the hand-operated rod 15, and symmetrically arranged second grooves 10 on the inner side of the square frame plate 2. A square plate 12 is slidably connected inside the second groove 10, and its outer surface is rotatably connected to the outer end of the dust roller 14. A rotating rod 19 is rotatably connected to the inner side of the second groove 10, a take-up wheel 18 is fixedly connected to the outer surface of the rotating rod 19, and a second gear 17 is fixedly connected to the outer end of the rotating rod 19. By setting the dust roller 14, it can roll and clean inside the square frame plate 2. At the same time, under the elastic force of the second spring 13, the dust roller 14 can be reset, thereby enabling secondary cleaning of the square frame plate 2 and preventing... Dust may enter the interior of the square plate 2. A second spring 13 is fixedly connected to the inner side of the second slide 10. The end of the second spring 13 away from the second slide 10 is fixedly connected to the outer surface of the square plate 12. Moving the square plate 12 can pull the second spring 13. A pull rope 11 is fixedly connected to the outer surface of the take-up reel 18. The end of the pull rope 11 away from the take-up reel 18 is fixedly connected to the outer surface of the square plate 12. During the winding process, the pull rope 11 will pull the square plate 12 to move along the interior of the second slide 10. The outer surfaces of the first gear 16 and the second gear 17 mesh. Rotating the first gear 16 can drive the second gear 17 to rotate. The outer surface of the sticky roller 14 contacts the charging port end face. Rotating the sticky roller 14 can clean the charging port end face.

[0022] Working principle: When the charging port is needed, the operator pulls any U-shaped plate 5. The U-shaped plate 5 moves along the L-shaped plate 4 under force. The movement of the U-shaped plate 5 drives the slider 20 to move along the inside of the first slide groove 8. The movement of the slider 20 will apply pressure to the first spring 9. The first spring 9 will contract under force until the U-shaped plate 5 slides out of the placement plate 6 and no longer limits the connecting groove bar 7. Then, the protective plate 3 is flipped, so that the side of the protective plate 3 that is limited by the U-shaped plate 5 rotates. The rotation of the protective plate 3 drives the connecting groove bar 7 to rotate inside the placement plate 6, thereby opening the square plate 2. This prevents the square plate 2 from opening in the event of an accidental impact and facilitates the maintenance and replacement of the protective plate 3, improving the practicality of the device.

[0023] When the charging port is not in use, the operator can rotate the hand crank 15. The rotation of the hand crank 15 drives the first gear 16 to rotate, which in turn drives the second gear 17 to rotate. The rotation of the second gear 17 drives the rotating rod 19 to rotate, which in turn drives the take-up reel 18 to rotate. The rotation of the take-up reel 18 will tighten the pull rope 11. During the tightening process, the pull rope 11 will pull the square plate 12 to move along the inside of the second slide groove 10. The movement of the square plate 12 will cause the sticky roller 14 to roll inside the square frame plate 2 to remove dust from the charging port end. When the sticky roller 14 becomes less sticky, it can be replaced. While the square plate 12 is moving, it will apply a pulling force to the second spring 13. The second spring 13 will be stretched and generate elastic force until the sticky roller 14 moves to the other end of the square frame plate 2. Then, the operator can release the hand crank 15. Under the action of the elastic force of the second spring 13, the sticky roller 14 can be reset, thereby enabling a secondary cleaning of the square frame plate 2 and preventing dust from possibly entering the inside of the charging port end.
