Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the template herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0046] like Figures 1 to 4 As shown, some embodiments of the utility model provide a handle device, which is mainly aimed at an emergency parachute system for quickly opening parachutes of heavy-weight (over 500kg) manned aircraft such as fixed-wing, tilt-rotor, and multi-rotor aircraft. The safety of the onboard personnel and property is effectively protected by relying on the onboard personnel to autonomously activate the parachute opening.

[0047] The handle device includes a connecting rod 200 , a handle body 100 , a latch 300 , a striker 400 , an electric contact 500 and a connecting structure 600 .

[0048] The connecting rod 200 defines a first connecting channel 210 , and the first connecting channel 210 penetrates the connecting rod 200 along the axial direction of the connecting rod 200 .

[0049] One end of the handle body 100 is at least partially slidably disposed in the first connection channel 210. It is understandable that a portion of one end of the handle body 100 is disposed in the first connection channel 210 and is slidably connected to the inner wall of the first connection channel 210, so that the handle body 100 can be pulled out of the first connection channel 210, reducing the friction between the handle body 100 and the inner wall of the first connection channel 210, so as to ensure the smoothness of the handle body 100 being pulled out of the first connection channel 210.

[0050] Along an axial direction perpendicular to the connecting rod 200, the latch 300 is penetrated through the connecting rod 200 and the handle body 100. Specifically, one end of the latch 300 is penetrated through the connecting rod 200 and a portion of the handle body 100 arranged in the first connecting channel 210, so that the connecting rod 200 and the handle body 100 are connected by the latch 300 to form a limiting structure to ensure the stability of the connection between the connecting rod 200 and the handle body 100.

[0051] It should be noted that the connecting rod 200 is connected to the handle body 100 by the latch 300 to prevent the handle body 100 from being pulled out of the first connecting channel 210 of the connecting rod 200, which not only ensures the stability of the connection between the connecting rod 200 and the handle body 100, but also improves the convenience of the connection between the connecting rod 200 and the handle body 100. In addition, the latch 300 can be removed to release the limiting effect between the connecting rod 200 and the handle body 100, so that the connecting rod 200 can be pulled out of the handle body 100.

[0052] The striker 400 is slidably disposed in the first connecting channel 210 , that is, the axis of the striker 400 coincides with the axis of the first connecting channel 210 , so as to ensure the smoothness and stability of the striker 400 during sliding in the first connecting channel 210 .

[0053] Specifically, the electric contact 500 is arranged at one end of the connecting rod 200 away from the handle body 100. It should be noted that in this embodiment, the electric contact of the electric contact 500 faces the striker 400, so that the striker 400 can contact the electric contact of the electric contact 500, thereby forming a circuit conduction.

[0054] In this embodiment, the electric contact 500 is used to be electrically connected to the timer. When the striker 400 contacts the electric contact 500, current conduction is formed, thereby triggering the timer, and a pulse current can be sent to the gas generator through the timer.

[0055] In addition, the connection structure 600 is slidably disposed in the first connection channel 210, one end of the connection structure 600 is connected to the handle body 100, and the other end of the connection structure 600 is connected to the striker 400, so that the handle body 100 and the striker 400 are connected through the connection structure 600. It can be understood that when the handle body 100 moves in a direction away from the connecting rod 200, the striker 400 can be driven to move synchronously through the connection structure 600, so that the connection structure 600 is pulled out of the first connection channel 210.

[0056] Furthermore, one end of the striker 400 away from the connection structure 600 is elastically connected to the connection rod 200 , so that the striker 400 can move toward the direction close to the electric contact 500 under the action of elastic force.

[0057] In this embodiment, the handle device has a first state and a second state.

[0058] Specifically, when the handle device is in the first state, there is a gap between the striker 400 and the electric contact 500. At this time, the handle body 100 is connected to the connecting rod 200 through the latch 300, thereby ensuring the stability of the handle device.

[0059] In addition, when the handle device is in the second state, the striker 400 contacts the electrical contact 500 to form current conduction and activate the timer.

[0060] Specifically, when the bolt 300 is pulled out from the handle body 100 and the connecting rod 200, and the handle body 100 is pulled, when the handle body 100 moves a preset distance along the axis direction of the striker 400 in a direction away from the electric contact 500, the striker 400 is driven to move synchronously through the connecting structure 600, thereby pulling the connecting structure 600 out of the first connecting channel 210. At this time, the connecting structure 600 is separated from the striker 400, so that the striker 400 moves in a direction close to the electric contact 500 under the action of elastic force and strikes the electric contact 500, so that the striker 400 forms a current conduction at the moment of striking the electric contact 500, thereby stimulating the timer.

[0061] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the handle body 100 includes a grip 110 and a pull rod 120 .

[0062] Specifically, one end of the pull rod 120 is connected to the handle 110 , wherein the connection between the handle 110 and the pull rod 120 includes any one of threaded connection, bolt connection, clamping, bonding or integral molding.

[0063] In addition, the other end of the pull rod 120 is at least partially accommodated in the first connecting channel 210 and is connected to one end of the connecting structure 600. The other end of the connecting structure 600 is movably connected to the firing pin 400, so that when the handle body 100 moves away from the firing pin 400, the connecting structure 600 is separated from the firing pin 400 when the connecting structure 600 is moved out of the first connecting channel 210.

[0064] like Figure 2 and Figure 4 As shown, in some embodiments of the present invention, the connection structure 600 includes a connection block 610 and a sphere 620 , and the connection block 610 is slidably disposed in the first connection channel 210 .

[0065] The connection block 610 defines a first clearance groove 611 on one side facing the striker 400, and the connection block 610 defines a through hole 612 on one side facing the handle body 100 that communicates with the first clearance groove 611. It should be noted that the axial direction of the through hole 612 is parallel to or coincides with the axial direction of the first connection channel 210.

[0066] Along the axial direction perpendicular to the through hole 612 , two opposite sides of the connecting block 610 are respectively provided with connecting holes 613 communicating with the first giving way groove 611 , and a part of the ball 620 is received in the connecting hole 613 .

[0067] In this embodiment, the number of the spheres 620 is two, and one sphere 620 is correspondingly received in one connecting hole 613 .

[0068] Specifically, the ball 620 contacts the inner wall of the first connecting channel 210 , and another part of the ball 620 is received in the first evacuation groove 611 .

[0069] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, one end of the firing pin 400 close to the handle body 100 is inserted into the first clearance groove 611, and the outer wall of the firing pin 400 contacts the groove wall of the first clearance groove 611 to limit the firing pin 400 and prevent the firing pin 400 from shaking in the first clearance groove 611.

[0070] The side wall of the striker 400 is provided with an annular groove 410 communicating with the connecting hole 613, and the ball 620 is at least partially received in the annular groove 410. It can be understood that one side of the ball 620 contacts the inner wall of the first connecting channel 210, so that the inner wall of the first connecting channel 210 forms a limit on the ball 620 in a direction perpendicular to the axis of the first connecting channel 210, and the side of the ball 620 away from the inner wall of the first connecting channel 210 abuts against the groove wall of the annular groove 410, so that the groove wall of the annular groove 410 forms a limit on the ball 620, thereby ensuring the stability of the ball 620 in the connecting hole 613, and at the same time, the connecting block 610 and the striker 400 can be movably connected through the ball 620.

[0071] It should be noted that, since the ball 620 movably connects the connecting block 610 and the firing pin 400, that is, when the handle device moves from the first state to the second state, the connecting block 610 and the ball 620 are pulled out from the first connecting channel 210. At this time, the side of the ball 620 facing away from the firing pin 400 has an unlimited effect on the ball 620, so that the ball 620 is detached from the connecting block 610 and the firing pin 400, thereby separating the connecting block 610 from the firing pin 400.

[0072] like Figure 2 As shown, in some embodiments of the present invention, a limiting ring 211 is provided on the inner wall of the first connecting channel 210, and one end of the limiting ring 211 facing the handle body 100 abuts against the connecting block 610, so as to limit the connecting block 610 along the axial direction of the first connecting channel 210 through the limiting ring 211.

[0073] Among them, a connecting platform 420 is provided at the end of the firing pin 400 away from the handle body 100. The connecting platform 420 is a disc-shaped structure, and the side wall of the connecting platform 420 is in contact with the inner wall of the first connecting channel 210, so as to form a limiting effect on the connecting platform 420 through the inner wall of the first connecting channel 210 to prevent the firing pin 400 from shaking in the first connecting channel 210, thereby ensuring the smoothness and stability of the sliding of the firing pin 400 in the first connecting channel 210.

[0074] In addition, an elastic member 800 is provided in the first connecting channel 210. It should be noted that the elastic member 800 may be a spring or an elastic rubber ring. Preferably, in this embodiment, the elastic member 800 is a spring.

[0075] Specifically, the elastic member 800 is sleeved on the striker 400 , one end of the elastic member 800 abuts against the limiting ring 211 , and the other end of the elastic member 800 abuts against the connecting platform 420 , so that the elastic member 800 is limited by the limiting ring 211 and the connecting platform 420 .

[0076] It should be noted that when the handle device is in the first state, the elastic member 800 is in a compressed state, that is, along the axial direction of the first connecting channel 210, the elastic member 800 has an elastic effect on the limiting ring 211 and the connecting platform 420, so that the connecting platform 420 tends to move toward a square close to the electric contact 500 under the elastic force of the elastic member 800.

[0077] When the handle device changes from the first state to the second state, the elastic member 800 is gradually compressed and stores elastic potential energy. When the ball 620 falls off from the annular groove 410, the striker 400 moves toward the electric contact 500 under the elastic force of the elastic member 800. When the striker 400 hits the electric contact 500, it is the second state of the handle device.

[0078] like Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the electric contact 500 includes a first electric contact 510 and a second electric contact 520 which are arranged at intervals, and the first electric contact 510 and the second electric contact 520 are respectively used to connect to the timer.

[0079] The distances from one end of the first electrical contact 510 and the second electrical contact 520 respectively close to the connecting platform 420 to the connecting platform 420 are equal, so that when the striker 400 moves in a direction close to the electrical contact, the striker 400 can simultaneously contact the first electrical contact 510 and the second electrical contact 520, thereby electrically connecting the first electrical contact 510 and the second electrical contact 520 through the striker 400.

[0080] Along the axis direction of the striker 400 , the projections of the first electric contact 510 and the second electric contact 520 on the plane where the connecting platform 420 is located are placed on the connecting platform 420 , and the striker 400 can simultaneously connect the first electric contact 510 and the second electric contact 520 during the process of moving toward the electric contact 500 .

[0081] like Figure 3 and Figure 4 As shown, in some embodiments of the present invention, a receiving groove 121 is provided on the side of the pull rod 120 away from the handle, and the end portion of the connecting block 610 close to the handle is received in the receiving groove 121, so that the inner wall of the receiving groove 121 forms a limiting effect on the connecting block 610.

[0082] The pull rod 120 defines a second connection channel 122, and the second connection channel 122 and the receiving groove 121 are connected through a limiting hole 123. In this embodiment, the limiting hole 123 is connected to the through hole 612, and the axis of the limiting hole 123, the axis of the through hole 612 and the axis of the second connection channel 122 coincide with each other, so as to ensure the smoothness of the user in the process of pulling the handle body 100.

[0083] In addition, the pull rod 120 is connected to the connection structure 600 via a connection piece 700 , so that when a user pulls the pull rod 120 , the connection structure 600 is driven to move synchronously via the connection piece 700 , and the striker 400 is driven to move synchronously via the connection structure 600 .

[0084] Specifically, the connecting member 700 includes a first limiting portion 710, a connecting portion 720, and a second limiting portion 730. In this embodiment, the first limiting portion 710 and the second limiting portion 730 can be limiting balls or limiting blocks, respectively.

[0085] Among them, the first limiting portion 710 is accommodated in the second connecting channel 122, the first limiting portion 710 can slide in the second connecting channel 122, the second limiting portion 730 is accommodated in the first giving way groove 611, the second limiting portion 730 abuts against the striker 400, and the side of the second limiting portion 730 away from the striker 400 abuts against the bottom wall of the first giving way groove 611 to avoid the second limiting portion 730 from shaking in the first giving way groove 611, thereby ensuring the stability of the second limiting portion 730 in the first giving way groove 611.

[0086] In addition, one end of the connecting portion 720 is passed through the second connecting channel 122 and connected to the first limiting portion 710, and the other end of the connecting portion 720 is passed through the limiting hole 123 and connected to the second limiting portion 730, thereby connecting the first limiting portion 710 and the second limiting portion 730 through the connecting portion 720.

[0087] It should be noted that the diameter of the first limiting portion 710 and the diameter of the second limiting portion 730 are both larger than the diameter of the limiting hole 123 to prevent the first limiting portion 710 and the second limiting portion 730 from passing through the limiting hole 123 .

[0088] It should be noted that the connection part 720 can be any one of a connection rod 200, a connection line or a connection rope, and can be specifically set according to actual conditions.

[0089] In this embodiment, the connecting portion 720 is a connecting rope.

[0090] like Figure 1 As shown, in some embodiments of the present invention, a detection switch 900 is provided on a side wall of the connecting rod 200 , and the detection switch 900 is a metal spring, so that the state of the handle body can be detected by the detection switch 900 .

[0091] Specifically, the detection switch 900 detects whether the handle device is in the first state or the second state.

[0092] like Figure 2 and Figure 3 As shown, in some embodiments of the utility model, an annular groove is provided at one end of the pull rod 120 close to the connecting structure 600, and the annular groove is connected to the first connecting channel 210. A sealing ring 1000 is provided in the annular groove, and the side of the sealing ring 1000 facing away from the pull rod 120 abuts against the inner wall of the first connecting channel 210, so as to form a sealed connection structure 600 between the pull rod 120 and the connecting rod 200 through the sealing ring 1000, thereby preventing external liquid, dust or other impurities from entering the first connecting channel 210.

[0093] Some other embodiments of the present invention provide a parachute, comprising the handle device described in any of the above embodiments. It should be noted that the parachute has the structure and beneficial effects of the handle device in any of the above embodiments, which will not be described in detail here.

[0094] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0095] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0096] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention.
