[0002] A carry-on suitcase is a type of luggage designed specifically for travelers. It not only has the storage functions of a traditional carry-on suitcase, but also has a built-in electric drive system, allowing users to move around easily in large transportation hubs such as airports and train stations. The driven wheels of a carry-on suitcase are wheels that do not provide power or output torque. In a carry-on suitcase, the driven wheels are usually used in conjunction with the drive wheels to achieve stable movement and turning of the suitcase.

[0003] A search revealed that Chinese Patent CN210248747U discloses a suitcase with a transportation function. The patent addresses the issue that when people are in a rush at airports or train stations, or are tired from their journeys, suitcases often fail to provide effective convenience and instead become a burden, slowing down movement and affecting travel plans and mood. Therefore, this patent is designed to be simple to operate, highly practical, and optimize suitcase functionality to help people save time and improve travel efficiency during their journeys.

[0004] The aforementioned carry-on suitcase is easy to use. However, existing carry-on suitcases typically have wheels mounted on the bottom with multiple screws. This means that if the wheels are damaged during use, a screwdriver is needed to unscrew them. Since screwdrivers are often hard to find, it is difficult to disassemble and replace the wheels, increasing the complexity and difficulty of the replacement process and resulting in low replacement efficiency.

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.

[0032] As attached Figure 1-6 As shown, one embodiment of this utility model is provided: a replaceable and detachable driven wheel for a personal carry-on suitcase, including two wheel bodies 1, with a disassembly and assembly assembly provided between the two wheel bodies 1;

[0033] The assembly and disassembly assembly includes a mounting box 2, which is positioned between two wheel bodies 1. Two connecting grooves 3 are formed on the lower surface of the mounting box 2. A bidirectional screw 4 is rotatably connected inside the mounting box 2. A first bevel gear 5 is fixedly connected to the middle of the bidirectional screw 4. A second bevel gear 6 is rotatably connected to one side of the inner wall of the mounting box 2. The first bevel gear 5 and the second bevel gear 6 are meshed. A throttle 7 is fixedly connected to the middle of the second bevel gear 6. The connecting grooves 3 are used for the movement of the connecting block 9. The outside of the bidirectional screw 4 is set with threads in opposite directions. The arrangement of the first bevel gear 5 and the second bevel gear 6 facilitates the rotation of the bidirectional screw 4 by the throttle 7.

[0034] As attached Figure 3 As shown, the external thread of the bidirectional screw 4 has two moving blocks 8. The two moving blocks 8 are slidably connected inside the mounting box 2. A connecting block 9 is fixedly connected to the lower surface of the moving block 8. The connecting block 9 is slidably connected inside the connecting groove 3. A limiting block 10 is fixedly connected to one side of the connecting block 9. A first locking block 11 is fixedly connected to one side of the limiting block 10. When the two moving blocks 8 are close to each other, it is easy to drive the two second locking blocks 14 out of the groove 15. When the two moving blocks 8 are far apart, it is easy to limit one side of the wheel body 1. The limiting block 10 is easy to limit one side of the wheel body 1.

[0035] As attached Figure 4 As shown, mounting brackets 12 are fixedly connected to both sides of the upper surface of mounting box 2. A rotating shaft 13 is rotatably connected to one side of mounting bracket 12. A second locking block 14 is fixedly connected to one end of the rotating shaft 13. The rotating shaft 13 facilitates the rotation of wheel 1, and the second locking block 14 facilitates the installation and limiting of the other side of wheel 1.

[0036] As attached Figure 5 As shown, a slot 15 is provided in the middle of the wheel body 1 for the installation of the first locking block 11 and the second locking block 14.

[0037] As attached Figure 1 As shown, two fixing plates 16 are fixedly connected to the upper surface of the mounting box 2. The two fixing plates 16 are arranged between the two mounting brackets 12. The fixing plates 16 facilitate the installation of the whole on the suitcase through the connectors.

[0038] As attached Figure 6As shown, the inner wall of the mounting frame 12 is provided with a cleaning component, which includes two fixed shells 17. The two fixed shells 17 are fixedly connected to the inner wall of the mounting frame 12. Two springs 18 are fixedly connected to the inner wall of the mounting frame 12. The springs 18 are located inside the fixed shells 17. One end of the spring 18 is fixedly connected to a sliding plate 19. The sliding plate 19 is slidably connected to the inside of the fixed shells 17. A connecting post 20 is fixedly connected to the lower surface of the sliding plate 19. A scraper 21 is fixedly connected to one end of the two connecting posts 20. A plurality of cleaning bristles 22 are provided on the lower surface of the scraper 21. The springs 18 are used to push the connecting posts 20 through the sliding plate 19, so that the cleaning bristles 22 are in contact with the wheel body 1.

[0039] Working principle: After the entire unit is installed at the bottom of the transportation box using the fixing plate 16, when the wheel 1 needs to be disassembled and replaced, turn the handle 7. When the handle 7 drives the second bevel gear 6 to rotate, the second bevel gear 6 drives the first bevel gear 5 to rotate, which in turn drives the first bevel gear 5 to rotate, thereby driving the bidirectional screw 4 to rotate. The external of the bidirectional screw 4 is set with threads in opposite directions, which causes the two moving blocks 8 to slide closer to each other inside the mounting box 2, causing the connecting block 9 connected to it to move. This causes the two connecting blocks 9 to move closer to each other, which causes the limiting block 10 to open up the distance from one side of the wheel 1, and the first locking block 11 to disengage from the corresponding slot 15. At this time, one side of the wheel 1 is released from the limiting position. Then, the wheel 1 is taken out from the side where the limiting position is released, so that the second locking block 14 disengages from the slot 15, thereby disassembling the wheel 1 for replacement. The operation is reversed during installation.

[0040] As the wheel 1 rolls, after the outer surface of the wheel 1 contacts the ground, the lower surface in contact with the ground will rotate to the upper surface due to the rotation of the wheel 1. Then, under the action of the spring 18 pushing the sliding plate 19 and the connecting column 20, the scraper 21 is pushed to stick to the surface of the driven wheel. Then, as the wheel 1 rotates, the cleaning bristles 22 will scrape away the small stones and branches connected to the wheel 1, thus cleaning the wheel 1.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
