Self-supporting, self-inflating and self-adapting tire device and method

Abstract

The invention relates to a self-supporting, self-inflating and self-adapting tire device for a scooter; with a vacuum tire structure, a peristaltic pump for inflating is arranged at a bead on at least one side. The peristaltic pump is a sealed long pipe which is the same as a bamboo joint or is made of a cup-shaped elastic pipe, an inclined opening is formed in each bamboo joint air pipe joint, and a one-way ventilation flap valve is formed. And the pump pipe is arranged around the tire. A pipe orifice of the peristaltic pump is used as an air inlet and leads to an outer rim opening; a one-way inflation valve is arranged at the tail of the tube and leads to a tire according to the invention, the tires are inflated in a rolling mode according to the weight of a rider, so that the inflation pressure is automatically adjusted, the phenomenon that inflation is too sufficient is avoided, the situation of under-pressure is avoided, the problem of bumping of the scooter is ingeniously solved through self-adaption, the performance of reducing rolling resistance is considered, and the continuous mileage of the electric scooter is increased by 10%. The three functions of self-supporting, self-inflating and self-adapting are perfectly achieved.

Description

technical field [0001] The present invention relates to a pneumatic tire, more particularly to an adaptive self-inflating tire device for a scooter. Background technique [0002] Personal means of transport on the market are mainly two-wheeled vehicles, such as bicycles and kick scooters. In particular, the social ownership of scooters has grown rapidly, and a large number of them are electric scooters. The tires used are mainly divided into two categories; one is inflatable tires, which need to be inflated frequently, which is very cumbersome; the second is non-inflatable tires. It is a solid core tire, and there are also foam materials or hollow structures, but it has high rolling resistance, heavy weight, poor shock absorption effect, high sliding resistance, and poor user experience. [0003] Vacuum tires have good airtightness, but in order to ensure the self-sealing performance of self-expanding, usually vacuum tires often require tires with thicker bead; if the bead ...

Problems solved by technology

In particular, the social ownership of scooters has grown rapidly, and a large number of them are electric scooters. The tires used are mainly divided into two categories; one is inflatable tires, which need to be inflated frequently, which is very cumbersome; the second is non-inflatable tires. It is a solid core tire, and there are also foam materials or hollow structures, but it has high rolling resistance, heavy weight, poor shock absorption effect, high sliding resistance, and poor user experience.

[0003] Vacuum tires have good airtightness, but in order to ensure the self-sealing performance of self-expanding, usually vacuum tires often require tires with thicker bead; if the bead is thicker than 4mm, it will cause media loss due to rolling deformation Larger, greater resistance, will shorten the driving distance of electric scooters by about 10%

[0004] If you need to improve efficiency and reduce rolling resistance, you need a very thin bead tire, such as a thickness of less than 2mm. If it is made into a vacuum tire, you will encounter insufficient outward support of the bead, and the initial state after installation cannot guarantee self-sufficiency. tightness, the initial inflation function cannot be realized

[0005] In addition, the tires of scooters and bicycles are small in size and have little air in the tire volume, so they need to be replenished frequently, and an additional pump is required, which brings inconvenience to users.

[0006] For electric scooters, no matter what kind of pneumatic tires are used, because the wheel hub is occupied by the motor, there is no place for traditional air nozzles to be placed at all.

In addition, the diameter of the scooter wheel is small, and the contradiction between inflating too much at one time and not being able to ride without pressure
