Preferably, described inflation inlet is connected by connecting tube is fixing with high-pressure pump.
Compared with prior art, the invention has the beneficial effects as follows: this inventive structure is scientific and reasonable, safe and convenient to use, by speed
Degree sensor detects the travel speed of vehicle in real time, and passes information to micro-computer controlling apparatus, when automobile in the process of moving
When crashing, micro-computer controlling apparatus controls the ejection speed of air bag according to speed, makes the power that air bag ejects
Degree minimizes, and reduces and gives driver or occupant the injury brought because the dynamics of air bag ejection is excessive.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely retouched
State, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the present invention
In embodiment, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise,
Broadly fall into the scope of protection of the invention.
Referring to Fig. 1 and Fig. 2, the present invention provides a kind of technical scheme: a kind of air bag with velocity sensor, including
Eject speed control unit 2 and velocity sensor 7, eject speed control unit 2 and be arranged on the top of control chamber 3, and eject
Speed control unit 2 be provided above air bag 1, the lower section of air bag 1 is provided with inflation inlet 10, control chamber 3
Right side is provided with installation sheet 4, and the inner bottom of control chamber 3 is respectively arranged with high-pressure pump 8 and micro-computer controlling apparatus 9, speed
