Abstract

The invention discloses an airbag device for a wheel, which relates to the field of vacuum tire safety devices. A tire pressure monitoring device is installed on a hub of a wheel, a gas generator is arranged on a rim of the hub, a supporting airbag capable of being filled in a tire after being inflated and expanded is connected to the gas generator, the tire pressure monitoring device is connectedwith an electronic controller, and the electronic controller is connected with a starting device of the gas generator. The gas generator is structurally characterized in that a barrel-shaped outer shell with an opening in the front end is arranged, propellant is contained in the outer shell, an igniter of the propellant is arranged in the outer shell, and a supporting airbag is installed at the front end of the outer shell; the supporting airbags are stacked in a fragile airbag shell when not inflated and expanded, and the airbag shell is fixedly connected with the outer shell. The appearanceof the tire can be recovered when the tire is damaged, so that a vehicle can normally run and brake, and secondary accidents caused by sudden tire burst are avoided.

Description

technical field

[0001] The invention relates to the field of safety devices for vacuum tires, in particular to a vacuum tire applied to the fields of new energy vehicles, ordinary cars, electric vehicles, motorcycles, etc., which can restore the shape of the tire when it is damaged, so that the vehicle can run normally and brake, and avoid sudden An airbag device for the wheel of a secondary accident caused by a flat tire. Background technique

[0002] We know that with the development and progress of society, the number of various vehicles has increased rapidly, and the driving safety of vehicles has received more and more attention from OEMs and consumers. At present, major automobile manufacturers are actively exploring and developing their own safety systems for automobile run-flat tires. The current plan is to use special tires, strengthen the tire wall thickness, and can run for dozens of kilometers under a certain speed, or use tire pressure sensors. Prevention in ad...
