[0018] The utility model is further explained in connection with the drawings and specific implementation.

[0019] A kind of anti-deformation aluminum alloy hub with shock-absorbing and buffering structure, as shown in Figures 1-5As shown, the device includes a hub body 1, a main shaft 5, elastic spokes 2, a rotating shaft 3, a rotating ring 4, a hydraulic assembly, a non-Newtonian fluid 51, fixed spokes 6, and an elastic body 7. The hub body 1 is made of aluminum alloy. The main shaft 5 is installed inside the hub body 1. At least six elastic spokes 2 are circumferentially spaced on both the front and rear sides of the inner wall of the hub body 1. The ends of the elastic spokes 2 away from the inner wall of the hub body 1 are rotatably connected to the rotating shaft 3. Rotating rings 4 are connected between the rotating shafts 3. The rotating rings 4 are rotatably connected to the main shaft 5. The rotating rings 4 are hollow inside. A hydraulic assembly is connected between the main shaft 5 and the rotating rings 4. The main shaft 5 is hollow inside, and a non-Newtonian fluid is installed in the hollow part of the main shaft 5. Fluid 51, a non-Newtonian fluid, behaves like an ordinary liquid at low speeds, but hardens rapidly under larger impacts, exhibiting solid-like properties. This allows the non-Newtonian fluid 51 to instantly increase damping when encountering sudden impacts, effectively protecting the main shaft 5 and its internal structure, and further reducing the vibration load transmitted to key components such as the motor and battery. It can achieve intelligent vibration reduction without the need for sensors or control systems, resulting in high reliability and low maintenance costs. At least four arched fixed spokes 6 are connected between the main shaft 5 and the inner wall of the hub body 1. Elastic spokes 2 are located on the front and rear sides of the fixed spokes 6. Each fixed spoke 6 has an elastic body 7 connected inside, and the elastic body 7 is made of highly elastic silicone.

[0020] like Figure 1 , Figure 2 and Figure 5 As shown, the hydraulic assembly includes a fixed ring 8, a pressure block 9, a fixed block 10, and hydraulic oil 11. Fixed rings 8 are connected to both the front and rear sides of the outer wall of the main shaft 5, and fixed blocks 10 are connected to both the front and rear sides of the inner wall of the rotating ring 4. The side of the fixed ring 8 closest to the fixed block 10 is open. Hydraulic oil 11 is provided inside each fixed ring 8. A pressure block 9 for preventing leakage of hydraulic oil 11 is slidably connected inside the fixed ring 8. The fixed blocks 10 are in contact with the pressure block 9.

[0021] When the battery car passes through the pit, the hub body 1 is subjected to a large impact force, so that the elastic spokes 2 are slightly rotated along the rotating shaft 3, so that the rotating ring 4 is slightly rotated along the main shaft 5, and the rotating ring 4 rotates and drives the fixed block 10 to extrude the pressing block 9, the pressing block 9 is slid into the fixed ring 8 and extrudes the hydraulic oil 11, so that the pressure in the fixed ring 8 rises, when the battery car completely walks out of the pit, under the pressure of the hydraulic oil 11, the pressing block 9 is reversely slid and reset, the pressing block 9 is reset to make the fixed block 10 reversely move, so that the fixed ring 8 is reversely reset, and the original state is automatically restored, which can effectively relieve the rigid collision between the elastic spokes 2, the rotating ring 4 and the main shaft 5, reduce the wear and fatigue damage, thereby prolonging the service life of the hub as a whole and improving the riding comfort, when the battery car normally drives, the arched structure of the fixed spoke 6 can provide excellent bending deformation resistance for the aluminum alloy hub, the elastomer 7 in the fixed spoke 6 can absorb and dissipate the impact energy from the road, and can also provide stable connection support between the main shaft 5 and the hub body 1, so that the aluminum alloy hub is more solid and reliable, even if the elastic spoke 2 deforms or buffers, it can also maintain the basic mechanical stability, under the action of the elastomer 7, the fixed spoke 6 can also absorb the high-frequency vibration of the hub body 1 to a certain extent, thereby prolonging the service life of the aluminum alloy hub.
