Problems solved by technology
At present, major automobile manufacturers are actively exploring and developing their own safety systems for automobile run-flat tires. The current solution 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 advance, but there are certain defects, special reinforced tires, difficult installation, poor driving noise and comfort, tire pressure sensor can only prevent early warning of high or low tire pressure, unexpected accidents when the tire hits or pushes against sharp objects If the tire blows out, it will not work at all and will not play a safe role

Embodiment Construction
[0015] Such as figure 1 , 2 The shown airbag device for the wheel is equipped with a tire pressure monitoring device on the wheel hub 16 (at the rim or the valve), and a gas generator is installed on the rim of the wheel hub 16 inside the tire, and the gas generator is connected with a After being inflated, the supporting air bag can be filled in the tire, the tire pressure monitoring device is connected with an electronic controller, and the electronic controller is connected with the starting device of the gas generator. from image 3 It can be seen from the figure that the structure of the gas generator is as follows: a barrel-shaped outer casing 8 with an open front end is provided, the outer casing 8 is a pressure-resistant steel cylinder, and the outer casing 8 contains a propellant 11. 11 is a gas generating agent, select sodium azide NaN3 and other substances that can decompose in a short time (30 milliseconds) and release a large amount of gas. The igniter 10 of pr...

The invention discloses an airbag device for a wheel, and relates to the field of safety devices for vacuum tires. A tire pressure monitoring device is installed on a wheel hub of the wheel, a gas generator is arranged on a wheel rim of the wheel hub, a supporting airbag which can be filled in a tire after inflation is connected to the gas generator, the tire pressure monitoring device is connected with 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 open front end is arranged, a propellant is contained in the outer shell, an igniter of the propellant is arranged in the outer shell, and the supporting airbag is arranged at the front end of the outer shell; and the supporting airbag is stacked in a fragile airbag shell when not inflated, and the airbag shell is fixedly connected with the outer shell. According to the airbag device,when the tire is damaged, the shape of the tire can be restored, so that a vehicle can normally run and brake, and secondary accidents caused by sudden tire burst can be 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...
