Description

Technical Field

[0001] The invention belongs to the technical field of protection and life-saving, and in particular to an active separation device for an integrated helmet and an ejection seat during ejection life-saving and a use method thereof. Background Art

[0002] The integrated helmet is a new type of helmet that integrates AR technology. It integrates the optical system into the protective helmet and connects to the seat socket through a cable plug to achieve data interaction with the aircraft's electronic components. Therefore, compared with ordinary protective helmets, during the ejection lifesaving process, the integrated helmet needs to first separate the cable plug from the seat socket to ensure the normal separation between the subsequent pilot and the ejection seat.

[0003] The traditional integrated helmet cable separation adopts a passive separation method, that is, the cable plug is connected to the pilot's clothing through a steel cable hook. When the pilot's seat is not completely separated, the speed difference between the pilot and the ejection seat is used to pull the cable plug to separate it from the ejection seat socket. This traditional method is greatly affected by the posture of the pilot's seat and the separation angle during separation, and it is impossible to accurately control the separation timing; in daily use, the cable hook needs to be hooked with the pilot's clothing, which is not convenient for daily use.

[0004] Therefore, it is necessary to study the separation method of the pilot and the ejection seat and determine a new separation method that is convenient for daily use and ensures the smooth separation of the cable plug and the ejection seat socket during ejection and life-saving. Summary of the invention

[0005] Purpose of the Invention

[0006] In order to overcome the above-mentioned shortcomings of the traditional integrated helmet cable separation method, the present invention provides an active separation device for the integrated helmet and the ejection seat during ejection lifesaving and a use method thereof.

[0007] Inventing technical solutions

[0008] The invention discloses an active separation device for an integrated helmet and an ejection seat during ejection lifesaving, comprising an anti-loosening connector, a lever clamping mechanism, an electrically excited gunpowder gas mechanism, and a socket fixing mechanism, all of which are fixed on the ejection seat; the fulcrum of the lever clamping mechanism is connected to the socket fixing mechanism, the power end of the lever clamping mechanism is aligned with the electrically excited gunpowder gas mechanism, the resistance end of the lever clamping mechanism corresponds to the spring self-locking mechanism on the anti-loosening connector of the anti-loosening connector; the socket of the anti-loosening connector is fixed by the socket fixing mechanism; a pull-out steel cable is installed on the unlocking mechanism of the plug, and when the plug is inserted into the socket, the resistance end of the lever clamping mechanism is pressed between the plug and the socket by the unlocking mechanism of the plug and is fixed by the unlocking mechanism of the plug and cannot rotate freely.

[0009] Preferably, the pull-off steel cable is fixed along the cable axis by a steel cable fixing ring.

[0010] Preferably, the power end of the lever clamping mechanism is flat and has a sufficient force-bearing area.

[0011] Preferably, the lever clamping mechanism includes a long arm and a short arm, which are fixed and rotatably arranged on a rotating shaft, the rotating shaft is fixed on the ejection seat, the nozzle of the electrically excited gunpowder gas mechanism is aligned with the long arm, and the short arm can be clamped on the spring self-locking mechanism on the plug.

[0012] Preferably, sufficient space is left on the upper part of the pull-off cable for hand operation.

[0013] Preferably, the electrically-activated gunpowder gas mechanism can be triggered by an ejection seat program controller.

[0014] Preferably, the plug has a plug alignment and positioning mark.

[0015] Preferably, the socket has a socket alignment and positioning mark.

[0016] The invention discloses a method for using a device for actively separating an integrated helmet and an ejection seat during ejection lifesaving. When a plug needs to be inserted into a socket, the plug is placed above a lever clamping mechanism, and then the plug is inserted into the socket, and a spring self-locking device is activated to firmly fix the plug, the lever clamping mechanism, and the socket; when release is required, the upper part of a pull-out steel cable is pulled, and the pull-out steel cable moves axially, driving the spring self-locking device to unlock, and further driving the plug to move axially along the cable, so that the plug is separated from the socket, thereby realizing the separation of the integrated helmet and the ejection seat for daily use.

[0017] Preferably, during ejection life-saving, the ejection speed and posture are judged by the ejection seat program controller, and when in a suitable state, the electrically excited gunpowder gas mechanism installed on the ejection seat is excited through the circuit, so that the gunpowder in the electrically excited gunpowder gas mechanism burns and generates gas. The erupted gas impacts the power end of the lever clamping mechanism, causing the power end to fall and the resistance end of the lever clamping mechanism to tilt up. The movement of the resistance end of the lever clamping mechanism pushes the spring self-locking mechanism of the anti-loosening connector to move upward, overcome the unlocking force, and further push the plug upward, so that the plug is separated from the socket, thereby realizing the active separation of the integrated helmet and the ejection seat for emergency ejection.

[0018] The advantages of the present invention are as follows: during ejection life-saving, the technology of active separation of integrated helmet and seat is a blank in the domestic life-saving field. The present invention performs ejection life-saving by active separation, and can artificially control the speed and posture of separation between person and chair during life-saving, thereby effectively improving the success rate of ejection life-saving in complex life-saving environments, and has great practical value and prospects.

DETAILED DESCRIPTION

[0024] The present invention is achieved through the following technical solutions.

[0025] An active separation device for an integrated helmet and an ejection seat during ejection lifesaving, including an anti-loosening connector. A suitable anti-loosening connector should be selected according to the use requirements of the integrated helmet circuit. The anti-loosening connector includes a plug 4 and a socket 7, wherein a pull-out steel cable 1 is installed on the unlocking mechanism of the plug 4, and the pull-out steel cable 1 is fixed along the axis of the cable 3 through a steel cable fixing ring 2, and sufficient space is left on the upper part of the pull-out steel cable 1 for hand operation.

[0026] With the ejection seat 8 as a fixed reference, the electrically excited gunpowder gas mechanism 9 is fixed to the ejection seat 8, the socket 7 can be connected to the ejection seat 8 through the socket fixing mechanism 11, and is firmly fixed to the designed position of the ejection seat 8, a rotatable lever clamping mechanism 10 is installed in the middle of the socket fixing mechanism 11, the fulcrum of the lever clamping mechanism 10 is connected to the socket fixing mechanism 11, forming a lever structure, the power end of the lever clamping mechanism 10 is aligned with the electrically excited gunpowder gas mechanism 9, and the resistance end of the lever clamping mechanism 10 corresponds to the spring self-locking mechanism on the plug 4 of the anti-loosening connector, so that when the plug 4 is inserted into the socket 7, the resistance end of the lever clamping mechanism 10 can be pressed into the space between the plug 4 and the socket 7 by the unlocking mechanism, and is fixed by the unlocking mechanism of the plug 4, and cannot rotate freely. The power end should be flat and have a certain force-bearing area.

[0027] The plug 4 has a plug alignment and positioning mark 5 , and the socket 7 has a socket alignment and positioning mark 6 .

[0028] The lever mechanism 10 includes a long arm and a short arm, which are fixed and rotatably arranged on a rotating shaft, the rotating shaft is fixed on the ejection seat, the nozzle of the electrically excited gunpowder gas mechanism 9 is aimed at the long arm, and the short arm is clamped on the spring self-locking mechanism.

[0029] In daily use, when insertion is required, place the plug above the clamping mechanism with one hand, adjust the alignment and positioning marks, then insert the plug into the socket, and the spring self-locking device will be activated to firmly fix the plug, the clamping mechanism and the socket; when release is required, pull the upper part of the steel cable with one hand, the steel cable will move axially, driving the spring self-locking device to unlock, and further driving the plug to move axially along the cable, so that the plug is separated from the socket, realizing the daily separation of the integrated helmet and the ejection seat.

[0030] During ejection life-saving, the ejection speed and posture are judged by the ejection seat program controller. When in a suitable state, the electrically excited gunpowder and gas mechanism installed on the seat is stimulated through the circuit, so that the gunpowder therein burns and generates gas. The erupted gas impacts the free end of the clamping mechanism, causing the free end to fall and the clamping end to tilt. The length difference between the long arm and the short arm of the lever is used to further enhance the thrust of the clamping end. The movement of the clamping end pushes the socket spring self-locking mechanism to move upward, overcomes the unlocking force, and further pushes the plug upward, so that the plug is separated from the socket, thereby realizing the active separation of the integrated helmet and the ejection seat for emergency ejection.
