Embodiment Construction
[0031] The present invention will be further described below in conjunction with accompanying drawing.
[0032] Such as figure 1 with 2 As shown, a fast driving device based on an airbag includes a housing 111, a reactive airbag 106, an ignition module, a thrust module, a material delivery gas circuit and a controller. The reaction airbag 106 has a cylindrical shape with both ends open. The ignition module includes a sealing cover 101 , an airbag front fixing ring 102 , an airbag front fixing sleeve 103 and a discharge electrode 104 . The sealing cover 101 is fixed to the inner end of the inner chamber of the casing 111 . Internal threads are provided on the inner side wall of the sealing cover 101 . The front fixing sleeve 103 of the airbag is in the shape of a hollow two-stage stepped shaft. The inner end of the shaft section with a larger shaft diameter of the front fixing sleeve 103 of the airbag is provided with an external thread. The inner end of the reaction airb...

The invention discloses a rapid driving device based on a gas bag and a driving method thereof. At present, the generation of the instant force mostly needs a solenoid coil with large power or a complex hydraulic system, and the cost is high. The rapid driving device comprises a shell, a reaction gas bag, an ignition module, a thrust module and a material conveying air path. The ignition module includes a sealing cover and a discharge electrode. The sealing cover is fixed in the shell. The inner end of the reaction gas bag is fixed with the sealing cover. The sealing cover is provided with a material inlet and is fixed with the discharge electrode. The thrust module comprises a rear fixing outer sleeve, a tail nozzle, a nozzle fixing sleeve and an elastic telescopic buffer rod. According to the rapid driving device of the invention, after the gas capable of reacting is introduced into the reaction gas bag, the gas is enabled to react violently and expand rapidly through discharge of the electrode, and then a large reverse thrust can be transmitted to the outside of the nozzle rapidly. The rapid driving device of the invention can be applied to occasions such as acceleration beforetakeoff of manned or unmanned aircrafts or quick escape in distress and the like.
Description
technical field [0001] The invention belongs to the technical field of power generating devices, and in particular relates to an airbag-based fast driving device and a driving method thereof. Background technique [0002] At present, in some occasions, it is often necessary to generate a large force in an instant to meet some special requirements (requiring a higher initial velocity): such as the speed before the drone takes off, or the escape velocity of the underwater robot when it is in danger. Wait. However, at present, the generation of these instantaneous forces mostly requires high-power electromagnetic coils or complex hydraulic systems, and the cost is relatively high. Contents of the invention [0003] The object of the present invention is to provide a fast driving device based on an airbag and a driving method thereof. [0004] The invention relates to a fast driving device based on an air bag, which comprises a casing, a reaction air bag, an ignition module,...
