Description

Technical Field

[0001] This utility model relates to the field of vacuum tire hubs, specifically to a hub for an electric skateboard wheel. Background Technology

[0002] Electric scooters are a common mode of transportation. They consist of a handlebar, pole, front and rear wheels, and pedals. The front and rear wheels include rims and pneumatic tires. During riding, pneumatic tires often lack elasticity and wear resistance, and are prone to punctures when encountering nails or small stones. Therefore, to improve elasticity, wear resistance, and safety, tubeless tires are used to replace traditional tires. However, these tubeless tires require special disassembly and assembly equipment, and the disassembly and assembly process is time-consuming and laborious. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an electric skateboard wheel hub that has a simple structure, saves time and effort in disassembly and assembly, and has better sealing performance.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] An electric scooter wheel hub includes a left hub, a right hub, and fasteners. The inner sides of both the left and right hubs are provided with inner rings, and the inner rings on the left and right hubs are fixedly connected by fasteners. At least one annular groove is provided on the opposite side of the left and right hubs, and a sealing ring is built into the annular groove on the left and / or right hubs.

[0006] A further technical solution is that the inner rings on the inner sides of the left and right hubs are evenly distributed with through holes for fasteners to pass through and lock in place.

[0007] A further technical solution is that locking rings are also distributed along the upper edge of the left and right hub components, and the left and right edges of the vacuum tire are restricted between the locking rings and the outer ends of the left and right hub components, thus restricting the movement of the vacuum tire edges.

[0008] A further technical solution is that a vent is fixed on the left or right hub for inflating the vacuum tire.

[0009] The beneficial effects of this utility model are as follows: This utility model provides an electric skateboard wheel hub, which achieves quick assembly and disassembly through a detachable connection between the left and right hub components, making it more convenient, time-saving, and labor-saving; and more than one sealing ring is built into the left and right hub components, which can effectively prevent gas from escaping from the gap between the left and right hub components after inflation, thereby increasing the sealing effect. Attached Figure Description

[0016] The preferred embodiments of this utility model will be described in detail below so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of this utility model.

[0017] See Figures 1 to 4 As shown, an electric skateboard wheel hub includes a left hub 1, a right hub 3, and a fastener 4. The inner sides of both the left hub 1 and the right hub 3 are provided with inner rings 6, and the inner rings 6 on the left hub 1 and the right hub 3 are fixedly connected by the fastener 4. At least one annular groove 8 is provided on the opposite sides of the left hub 1 and the right hub 3, and a sealing ring 7 is built into the annular groove 8 on the left hub 1 and / or the right hub 3.

[0018] The inner rings 6 on the inner sides of the left hub 1 and right hub 3 have evenly distributed through holes 9 for fasteners 4 to pass through and lock in place. Locking rings 2 are also distributed along the upper rings of the left hub 1 and right hub 3, restricting the left and right edges of the tubeless tire between the locking rings 2 and the outer ends of the left and right hub 1 and right hub 3, thus limiting edge movement of the tubeless tire. A vent 5 is fixed to either the left hub 1 or the right hub 3 for inflating the tubeless tire.

[0019] In this embodiment, the fastener 4 is a bolt, nut, or other commonly used fastener, while there are 12 through holes 9 (six of which are used for fastening and fixing the left hub 1 and the right hub 3 to each other, and the other six through holes 9 are distributed alternately with the through holes 9 used for fastening the hubs, for fixing the electric scooter drive motor). There are two annular grooves 8 on the left hub 1 and the right hub 3, one large and one small. The sealing ring 7 is made of rubber, but it can also be made of other materials. The sealing ring 7 is placed in the annular groove 8 on either the left hub 1 or the right hub 3. Alternatively, sealing rings 7 can be placed in the annular grooves 8 on either the left hub 1 or the right hub 3. During installation, place the sealing rings 7 in the annular grooves 8 on either the left hub 1 or the right hub 3, then align the through holes 9 on the left hub 1 and the right hub 3, and then tighten them by using fasteners through the through holes 9. The sealing rings 7 prevent gas from escaping from the gap between the left hub 1 and the right hub 3. To disassemble, simply loosen the fasteners 4. When using, put the vacuum tire on the outer circumference of the left hub 1 and the right hub 3, and inflate it by connecting the air nozzle 5 with an inflation device.

[0020] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that are conceived without creative effort should be covered by the protection scope of this utility model.
