AI Technical Summary
Existing pneumatic tires are inadequate in terms of drainage performance and grip, and are prone to slipping, especially in rainy weather, thus failing to meet usage requirements.
A tire body was designed with multiple alternating drainage grooves on its outer surface, including a first arc-shaped groove, a middle connecting groove, and a second arc-shaped groove, forming an arc-shaped connected structure. Anti-slip protrusions are also extended on the outer surface to enhance drainage performance and grip.
The arc-shaped guide channel structure accelerates the water flow, improves drainage performance, and increases the drainage area. The raised structure provides intermediate support to prevent slippage, enhances grip, and ensures driving safety and comfort.

Abstract
Claims
1. A non-pneumatic tire comprising a tire body having an inner tread and an outer tread disposed opposite each other on the inner and outer sides of the tire body, the inner tread encircling a mounting cavity for receiving a wheel hub, characterized in that, The tread pattern of the tire is formed by multiple guide grooves arranged alternately. The guide grooves include a first arc-shaped groove, a middle connecting groove, and a second arc-shaped groove arranged sequentially from the outer edge of the tire tread inward. The first arc-shaped groove is formed by bending and extending inward from the outer edge of the tire tread, and the second arc-shaped groove is formed by bending and extending inward from the outer edge of the tire tread. The first arc-shaped groove and the second arc-shaped groove are connected by the middle connecting groove. The tire tread surrounded by the first arc-shaped groove, the middle connecting groove, and the second arc-shaped groove protrudes outward to form a raised structure for anti-skid purposes.
2. The non-pneumatic tire of claim 1, wherein, The cross-section of the protruding structure is a circle, a rectangle, or a triangle.
3. The non-pneumatic tire of claim 1, wherein, The protruding structure is provided in multiple ways, and the multiple protruding structures are evenly arranged on the outer tire surface surrounded by the first arc-shaped groove, the intermediate connecting groove and the second arc-shaped groove.
4. The non-pneumatic tire of claim 1, wherein, The guide grooves are arranged alternately on the left and right sides along the direction of the outer tire tread.
5. The non-pneumatic tire of claim 1, wherein, The length of the second arc-shaped groove is greater than the length of the first arc-shaped groove. The second arc-shaped groove is arranged wrappingly outside the first arc-shaped groove. The first arc-shaped groove, the intermediate connecting groove and the second arc-shaped groove together form an "H"-shaped structure.
6. The non-pneumatic tire of claim 1, wherein, The sidewall between the inner and outer tire treads is recessed downwards to form a right-angled stepped structure, and the side of the stepped structure closest to the inner tire tread has a reinforcing rib.
7. The non-pneumatic tire of claim 6, wherein, The reinforcing rib is a long, raised structure.
8. The non-pneumatic tire of claim 6, wherein, The reinforcing ribs are arranged at equal intervals along the direction of the circumference of the side tread.
9. The non-pneumatic tire of claim 1, wherein, The inner tube surface is provided with at least two rebound grooves. All the rebound grooves are arranged at equal intervals along the direction of the inner tube surface. A support portion for abutting the wheel hub is formed between two adjacent rebound grooves. There is a gap between the bottom groove wall of the rebound groove and the outer tire surface.
10. The non-pneumatic tire of claim 9, wherein, The cross-section of the rebound groove includes a first arc and a second arc connected in sequence. The first arc and the second arc are concave inward near the inner tube surface to form a concave structure. The connection between the first arc and the second arc is concave inward to form a concave structure.
