Description

Technical Field

[0001] The utility model relates to the technical field of parachute release, in particular to an automatic release device for a parachute bag. Background Art

[0002] In aerospace and skydiving, the automatic release device of the parachute bag is one of the key devices to ensure the safety of the skydiver. Traditional release devices mostly rely on manual pull ring operation. For example, the patent scheme with publication number CN212448116U shows a release ring design composed of large, medium and small steel rings connected to each other. The release ring serves as a connection device between the main parachute control belt and the auxiliary parachute control belt. By pulling the pull ring, the connection is quickly cut off, thereby achieving the separation of the main parachute and the skydiver and triggering the deployment of the auxiliary parachute. The defect of the existing technology is that in an emergency, such as when the skydiver loses consciousness, injures his hand or the pull ring device fails, manual release becomes impossible, thereby increasing the safety risk of the skydiver. Therefore, there is a need for an automatic release device that can automatically separate the parachute from the skydiver in an emergency. Utility Model Content

For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0026] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] like Figures 1 to 3 As shown, an automatic release device for a parachute bag comprises: a release ring 1, comprising a small ring, a middle ring and a large ring which are sleeved in sequence, the small ring being connected to the main parachute control belt of the parachute bag through a three-ring blocking rope 11, and the large ring being connected to the auxiliary parachute control belt of the parachute bag; a release assembly 2, comprising a shell, the interior of which is provided with a first chamber 3, a second chamber 4 and a third chamber 5; a piston 6 is provided in the first chamber 3, one side of the piston 6 and the first chamber forming a fuel chamber 7 for storing fuel, the other side of the piston 6 is connected to a push rod 8, the push rod 8 passes through the first chamber 3 and extends to the second chamber 4; a slider 24 is provided in the second chamber 4, one side of the slider 24 is connected to the push rod 8, and the other side is connected to the cutter 9, the shell is provided with a rope hole 10 which passes through the second chamber 4 for the three-ring blocking rope 11 to pass through; an ignition needle 12 is provided in the third chamber 5, one end of the ignition needle 12 extends into the fuel chamber 7; a controller 13 is provided on the auxiliary parachute control belt and is connected to the release assembly for driving the ignition needle 12 to ignite.

[0028] The main parachute control strap connects the parachute lines to the jumper's harness. When the main and reserve parachute control straps are tightly connected via the release ring 1, they form a stable connection system, tightly binding the jumper to the parachute. The release ring 1 is the connecting device between the main and reserve parachute control straps. It consists of large, medium, and small steel rings that fit together. Pulling the ring quickly disconnects the main and reserve parachute control straps.

[0029] In an emergency, such as when a skydiver needs to quickly detach from the parachute, this can be achieved by cutting the three-ring blocking rope 11. Specifically, the controller 13 generates or receives instructions to control the ignition needle 12 to ignite, causing a small explosion of fuel in the fuel chamber 7. The thrust of the explosion pushes the piston 6 to move linearly. The piston 6 drives the slider 24 and the cutter 9 to move linearly through the push rod 8. The cutter 9 cuts the three-ring blocking rope 11 as it passes through the rope hole 10, separating the detachment ring 1 from the main parachute control belt, thereby separating the main parachute control belt from the auxiliary parachute control belt, and finally separating the skydiver from the parachute bag.

[0030] The automatic release device provided in this embodiment serves as an emergency response measure. When the conventional pull ring release device fails, the three-ring blocking rope 11 of the pull ring is automatically cut off by setting the release component 2. The three-ring blocking rope 11 connecting the pull ring can be automatically cut off, and the connection between the main parachute and the parachutist can be automatically cut off in an emergency, and the auxiliary parachute can be triggered to deploy to ensure the safety of the parachutist.

[0031] The controller 13 can generate or receive instructions to automatically control the ignition of the ignition needle, eliminating the need for the parachutist to perform complex operations, thereby simplifying the separation process.

[0032] The thrust generated by the fuel explosion is large and rapid, which can ensure that the cutter cuts the three-ring blockade rope in a very short time, thereby improving the reliability of the device.

[0033] It should be noted that the fuel in the fuel chamber 7 is a mixture of combustible materials such as aluminum powder, boron powder, etc., oxidizers such as ammonium perchlorate, ammonium nitrate, etc., and adhesives such as polyurethane, epoxy resin, etc. It can burn rapidly under controlled conditions to generate high-temperature and high-pressure gas, providing powerful thrust, which is existing technology.

[0034] In some embodiments, the housing is provided with a fuel inlet 14, the inner side of which is connected to the fuel chamber 7, and the outer side of which is connected to a cover 15. In actual use, when fuel needs to be added to the fuel chamber of the trip assembly, the cover 15 can be opened and the fuel can be injected into the third chamber 5 through the fuel inlet 14. After the fuel is added, the cover is replaced to ensure the sealing of the fuel chamber 7.

[0035] In some embodiments, a pulse igniter 16 is provided within the controller 13. The pulse igniter 16 is connected to an ignition wire 17, which is connected to the third chamber 5 and the ignition pin 12. When the fuel needs to be ignited, the controller issues a command, and the pulse igniter 16 immediately generates a high-voltage electrical pulse. This electrical pulse is rapidly transmitted to the ignition pin 12 via the ignition wire. Upon receiving the electrical pulse, the tip of the ignition pin 12 generates a high-temperature spark, thereby igniting the fuel in the third chamber.

[0036] In some embodiments, a sleeve 18 is connected between the controller 13 and the trip assembly to enclose the ignition wire 17. After exiting the controller 13, the ignition wire 17 passes through the sleeve 18 and then connects to the third chamber 5 of the trip assembly 2 and the ignition pin 12. The use of the sleeve 18 protects the ignition wire 17 from environmental damage during transmission, ensuring stable transmission of the ignition signal.

[0037] In some embodiments, the controller 13 is equipped with a battery 19 and a circuit board 20. The battery 19 is electrically connected to the circuit board 20 and the pulse igniter 16, respectively. The circuit board 20 is used to control the battery 19 to start the pulse igniter 16. The battery 19 is connected to the circuit board 20 and the pulse igniter 16 via wires, forming a complete circuit. When the ignition process needs to be initiated, the circuit board 20 receives the corresponding command and controls the battery 19 to provide power to the pulse igniter 16, thereby triggering the ignition action.

[0038] In some embodiments, the circuit board 20 is connected to a wireless communication module for receiving wireless signals and controlling the battery 19 to start powering the pulse igniter 16. When an external ignition signal is sent, the wireless communication module receives the ignition signal, and the circuit board 20 quickly responds by controlling the battery 19 to supply power to the pulse igniter 16, thereby initiating the ignition process. This allows the ignition operation to be performed remotely, improving operational flexibility and convenience.

[0039] In some embodiments, a buffer block 21 is provided at one end of the second chamber 4 away from the cutter 9 to cushion the cutter 9. After the cutter 9 has completed its cutting task, it will continue to move forward due to inertia and generate vibrations. The provision of the buffer block 21 can effectively absorb the kinetic energy of the cutter 9, reducing its vibrations and ensuring the stability and safety of the cutter 9 after cutting.

[0040] In some embodiments, the sidewall of the second chamber 4 is provided with a mounting groove 22, within which a resilient tab 23 is disposed. A groove is provided on the sidewall of the slider 24. When the slider 24 is in its initial position, the raised portion of the resilient tab 23 engages within the groove to position the slider 24. The design of the resilient tab 23 and the groove can reduce shaking and wear of the slider 24 in its initial position. The cooperation between the resilient tab 23 and the groove ensures the positioning accuracy of the slider 24 in its initial position, thereby improving the operational stability and reliability of the trip assembly.

[0041] In some embodiments, the automatic release device includes two release components 2, which are respectively connected to the three-ring blocking ropes 11 of the main parachute control belts on both sides. The controller 13 is connected to the two release components 2 and is used to control the two release components 2 to synchronously cut the two three-ring blocking ropes 11.

[0042] Specifically, the two ignition wires 17 connected in the controller 13 ignite the ignition pins 12 in the two tripping assemblies 2 respectively, accurately control the synchronous action of the two tripping assemblies 2, and cut the three-ring blocking rope 11 of the two main parachute control belts to ensure that the parachutist can escape from the main parachute in an emergency.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
