Detailed Description

The technical scheme protected by the utility model is specifically described below with reference to the accompanying drawings.

Referring to fig. 1 and 2, the present utility model provides a tire for an all-purpose electric vehicle, which comprises a tread, wherein a first zigzag pattern groove 11 and a second zigzag pattern groove 31 are arranged on the tread, and the first shoulder pattern area and the second shoulder pattern area are staggered and symmetrical left and right along the center of the tread. The tread is divided into a first shoulder pattern area 1, a central tread pattern area 2 and a second shoulder pattern area 3 by the first zigzag pattern groove 11 and the second zigzag pattern groove 31 in sequence. The central tread pattern area 2 is designed as a smooth tread, which gives the tire a strong rigidity and a low creep loss.

The first shoulder pattern area 11 is provided with an 'h' -shaped pattern groove 12 and an anti-skid tread 13, the 'h' -shaped pattern groove 12 is communicated with the first sawtooth-shaped pattern groove 11, the anti-skid tread surrounded by the 'h' -shaped pattern groove on the tread is provided with diamond particle patterns 15, the anti-skid tread 13 is provided with wavy anti-skid patterns 45 degrees with the center of the tread, and the patterns are staggered, so that the high aesthetic value is brought. The design of the wavy patterns increases the anti-skid performance and the grip of the tire, reduces the vibration of the tire in the running process, greatly improves the running safety, and can effectively prevent the vehicle from sideslip in the running process. The h-shaped groove 12 has excellent drainage performance, and can increase resistance and reduce extrusion force between the blocks. The irregular square pattern blocks 14 are arranged between the anti-skid tread 12 and the first-number zigzag pattern grooves 11, and the irregular square pattern blocks 14 can play a role in protecting wavy anti-skid patterns and diamond particle patterns 15.

In one embodiment, the groove depth of the first zigzag groove 11 and the second zigzag groove 31 is 4.5mm, the groove width is 5.1mm, and the groove width is wider than the groove width arranged on the tread of a common tire, so that the tire has better functions of draining water and discharging mud, the rolling resistance of the tire can be reduced, the sizing material used by the tread can be reduced, the purpose of reducing the weight of the tire carcass is achieved, meanwhile, the sliding distance is reduced by adopting irregular zigzag grooves on two sides, and the service life of the tire is prolonged.

In another embodiment, the diamond grain pattern 15 has a grain height of 1.5mm, and the diamond grain of a common tire has a grain height of 1mm, and the diamond grain of the tire is designed to be larger than the diamond grain of the common tire, so that the tire tread of the present utility model has better skid resistance, better shock absorption effect and more beautiful appearance.

The first serrated pattern groove 11 is communicated with the side, close to the central tread pattern area 2, provided with the auxiliary groove 16, and the main groove is provided with the functional auxiliary groove, so that a water film can be effectively broken, and the tire tread has certain aesthetic property while the running safety performance is improved.

The steel wire layer designed in the tire adopts the car-grade steel wire, so that the puncture-proof capability of the tire is greatly improved, the inner tube can be greatly protected from being punctured, the tire burst-proof effect is achieved, the tire can run on a road section with broken stone such as a mountain area more safely, and the risk of broken stone to burst the tire tread is avoided.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
