Tire-burst-proof and anti-puncture durable electric vehicle outer tire structure

Abstract

The present invention relates to a tire-burst-proof and anti-puncture durable electric vehicle outer tire structure, wherein the tire body is filled with an elastomer made by carrying out mixing forming on plastic particles and a foaming agent, a layer of a rubber layer is embedded between the elastomer and the inner edge of the tire body, a cavity is arranged at the lower end position of the rubber layer, and the partial space of the cavity is filled with an explosion-proof rubber. According to the present invention, the plastic particles and the foaming agent are light, the whole body is light, the rubber layer and the tire body are integrally compounded, and the cavity on the lower end is filled with the explosion-proof rubber, such that the hole can be automatically blocked when the outer tire is punctured by the foreign matter; the two layers of the strengthened rubber layers and the hard rubber layer provide the further anti-puncture strengthening effect, such that the layered structure cannot be punctured by the general small nail and the small sharp objects; and the actual use results prove that the whole outer tire has characteristics of light weight, good elasticity, explosion resistance, and tire-burst resistance.

Description

technical field [0001] The invention belongs to the field of tire structures in vehicles such as electric bicycles or electric tricycles, in particular to a durable electric vehicle outer tire structure for run-flat and puncture-proof tires. Background technique [0002] The electric bicycle is a popular means of transportation. Its main structure is the frame, and the two wheels are installed on the front and rear ends of the frame respectively. The battery installed on the frame provides power for the motor, thus realizing In addition to the riding of electric bicycles, due to the large force of the motor, electric bicycles have the characteristics of fast riding speed and large load capacity. Electric tricycles are also a common means of transportation. The difference is that they are equipped with three wheels. The structure of the above-mentioned wheel includes a rim, an outer tire and an inner tube. The bead made on the outer tire is stuck in the groove made by the rim...

AI Technical Summary

Problems solved by technology

The structure of the above-mentioned wheel includes a rim, an outer tire and an inner tube. The bead made on the outer tire is stuck in the groove made by the rim, the outer edge of the outer tire is made with tread patterns or particles, and the inner tube is equipped with an air nozzle and can be filled with gas. The structure of the inner tube has the following problems: 1. There is air in the inner tube. When the inner tube is punctured, the air leaks, which makes the electric vehicle unable to continue riding; 2. The inner tube and the outer tire are in close contact, and there will be certain wear and tear after long-term use , prone to air leakage

[0003] Many manufacturers have invested manpower and material resources in research and development, and developed a variety of non-inflatable tires. The common structures include: the outer tire and inner tube are integrated rubber structure or the inner tube is a structure in which multiple rubber sections are bonded to each other. The first type is integrated. The overall weight is large, and the riding resistance is relatively large; the elasticity of the joint between the second multi-section rubber is different from that of the rest, resulting in uneven elasticity
