Abstract
Claims
1. An electric wheelchair hub comprising a rim (1) and spokes (2), said rim (1) being in the form of a ring structure, said rim (1) having fixed therein spokes (2), characterized in that: The spokes (2) are provided with hollow holes (3), which are evenly distributed on the spokes (2). The hollow holes (3) are a gradient polymorphic structure, with the empty area gradually increasing from the center of the spokes (2) towards the edge. The spoke (2) is provided with a connecting flange (5) at its center. The connecting flange (5) is fixedly installed on one side of the spoke (2) by a detachable connecting structure. The side of the connecting flange (5) is provided with several mounting grooves. The mounting grooves are provided with elastic blocks (9). The elastic blocks (9) are provided with anti-slip textures.
2. The electrically powered wheelchair hub of claim 1, wherein: The hollow holes (3) on the spokes (2) are in the shape of a gradually changing hexagon, and the hollow holes (3) are centrally symmetrically distributed on the spokes (2).
3. The electrically motorized wheelchair hub of claim 1, wherein: The elastic block (9) is made of rubber material with a diamond-shaped anti-slip pattern, and the elastic block (9) is embedded in the side of the connecting flange (5).
4. The electrically motorized wheelchair hub of claim 1, wherein: The rim (1), spokes (2) and connecting flange (5) are all made of high-strength aluminum alloy, and the rim (1) and spokes (2) are integrated.
5. The electric wheelchair hub according to claim 1, characterized in that: The detachable connection structure is connected by a nut (6) and a bolt (7). A fixing hole (4) is provided on the spoke (2). The fixing hole (4) is aligned with the connecting hole on the connecting flange (5). The bolt (7) passes through the fixing hole (4) and the connecting flange (5) and is connected to the nut (6), thus forming a fixing structure for the spoke (2) and the connecting flange (5).
6. The electric wheelchair hub of claim 1, wherein: The connecting flange (5) has a central hole (8) in the middle, and mounting holes (10) are provided around the central hole (8). The mounting holes (10) and the elastic locking block (9) are spaced apart.
