Abstract
The invention discloses a quick-triggering automatic gas cylinder puncturing device which mainly comprises a steering engine, a steering engine arm, a prying rod, a limiting sleeve cover, a high-rigidity spring, a sleeve, a puncturing needle and a gas cylinder. The steering engine drives the steering engine arm to rotate, the pry bar is not limited to the position of the puncture needle after the rotation angle of the steering engine arm changes, and elastic potential energy stored by the compressed high-stiffness spring in the limiting sleeve cover pushes the puncture needle to move towards the bottle opening of the gas cylinder to puncture the bottle opening, so that automatic puncture and deflation of the gas cylinder are realized. The automatic puncturing device for the gas cylinder has the characteristic of quick triggering, and the steering engine can trigger the puncturing device only by driving the steering engine arm to rotate by a very small angle. The device is suitable for portable quick inflation systems.
Description
Technical Field
The invention belongs to the technical field of gas cylinder triggering of rapid inflation systems such as human body safety protection airbags and relates to a rapid-triggered gas cylinder automatic puncturing device.
Background
In the sports safety of old people and the safety protection of motorcycle drivers, a human body safety airbag is needed to form a buffer layer between a human body and the ground, so that the protection effect is achieved. For such portable human body airbags, a corresponding fast-triggering automatic cylinder puncturing device is required to fill the airbag with gas in time.
The existing chemical explosion triggering device is not portable, and meanwhile, most micro-electromechanical triggering devices are poor in rapidity.
Disclosure of Invention
The invention realizes the quick triggering of the device by deeply researching and designing the automatic puncturing device of the gas cylinder, can be applied to portable human body safety airbags, and solves the problems mentioned in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme:
a quick-triggering automatic gas cylinder puncturing device comprises a steering engine, a steering engine arm, a prying rod, a limiting sleeve cover, a high-rigidity spring, a sleeve, a puncturing needle and a gas cylinder. The steering engine drives the steering engine arm to rotate, so that the pry bar with one end in contact with the steering engine arm is disturbed and does not limit the position of the puncture needle any more, and elastic potential energy stored by the compressed high-stiffness spring in the limiting sleeve cover pushes the puncture needle to move towards the opening of the gas cylinder and puncture the opening of the gas cylinder, so that rapid deflation is realized.
As a further scheme of the invention, the limiting sleeve cover is connected with the sleeve through threads, the puncture needle can slide in a cylindrical cavity in the sleeve, the high-stiffness spring is positioned between the limiting sleeve cover and the puncture needle base, and the high-stiffness spring is compressed to store elastic potential energy when the limiting sleeve cover is screwed with the sleeve.
As a further scheme of the invention, a rectangular groove is formed in the side face of the sleeve, one end of a prying bar can slide in the rectangular groove and limit the position of a pricking pin, and the other end of the prying bar can be in contact with the steering engine arm.
As a further scheme of the invention, when the steering engine drives the steering engine arm to rotate, one end of the prying rod is not contacted with the steering engine arm any more, and the prying rod can rotate freely after the limitation is lost, i.e. the position of the puncture needle is not limited any more. At the moment, the energy stored by the large-stiffness spring can push the puncture needle to move towards the opening of the gas cylinder and puncture the gas cylinder.
As a further scheme of the invention, the steering engine further comprises a fixing frame which can fix the positions of the steering engine and the sleeve.
As a further scheme of the invention, the gas cylinder and the sleeve are connected through threads, and compressed liquid CO2 is stored in the gas cylinder.
As a further scheme of the invention, the system also comprises a power supply and driving circuit of the steering engine.
The invention adopts the technical scheme that the method has the advantages that:
the characteristic of quick triggering is that the trigger of the puncture device can be realized only by rotating the rudder horn by a tiny angle. The steering engine drives the steering engine arm to rotate, so that the pry bar with one end in contact with the steering engine arm is disturbed and does not limit the position of the puncture needle any more, and elastic potential energy stored by the compressed high-stiffness spring in the limiting sleeve cover pushes the puncture needle to move towards the opening of the gas cylinder and puncture the opening of the gas cylinder, so that rapid deflation is realized.
Drawings
FIG. 1 is a schematic view of the overall apparatus of the present invention.
In the figure, 1-steering engine, 2-steering engine arm, 3-pry bar, 4-limiting sleeve cover, 5-large-stiffness spring, 6-felting needle, 7-sleeve, 8-gas cylinder and 9-fixing frame.
Detailed Description
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.
As shown in fig. 1, this example provides a technical solution: a quick-triggering automatic gas cylinder puncturing device comprises a steering engine 1, a steering engine 2, a steering engine arm 3, a pry bar 4, a limiting sleeve cover 4, a large-stiffness spring 5, a puncturing needle 6, a sleeve 7, a gas cylinder 8, a fixing frame 9 and the like.
The device installation process: install steering wheel and sleeve on the fixed bolster, wherein the steering wheel contains its steering wheel arm, and the sleeve is inside to contain the felting needle, and another pinch bar one end contacts with the steering wheel arm this moment, then can not slide in the rectangular channel of sleeve side owing to the position restriction other end. The spring with large rigidity is placed in the sleeve and is in contact with the base of the puncture needle, and the spring is in the original long state. The limiting sleeve cover is slowly screwed with the sleeve thread pair, and the pry bar limits the position of the puncture needle due to the fact that the other end of the pry bar is in contact with the steering engine arm, so that the large-stiffness spring is compressed.
The device triggering process comprises the following steps: the electric signal automatically makes the steering engine rotate a small angle, the pry bar is not in contact with the steering engine arm any more, and the limitation on the position of the puncture needle is removed. The elastic potential energy stored by the compressed high-rigidity spring in the limiting sleeve cover pushes the puncture needle to move towards the opening of the gas cylinder and puncture the opening of the gas cylinder, so that the gas cylinder is punctured and quickly deflated.
The above-mentioned embodiments are preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, and the equivalent changes in shape and structure according to the present invention are within the protection scope of the present invention.
