Description

Technical Field

[0001] The utility model belongs to the technical field of parachutes, and in particular relates to an automatic parachute opening device based on a titanium wire electric-controlled lock. Background Art

[0002] Marine observation equipment plays a vital role in marine safety, scientific research, climate change, and marine economic development. The deployment of small equipment such as buoys and gliders is suitable for airdrop. During airdrop, parachutes are usually used to slow down the marine observation equipment so that it enters the water at a safe speed to ensure that it is not damaged during airdrop.

[0003] Automatic parachute opening can greatly improve the efficiency of airdrop deployment. In the existing technology, the opening methods of parachutes with automatic parachute opening function can be divided into two types: spring-pushed type and gas-driven type. They are generally used for drones to prevent accidental crashes of drones.

[0004] Gas-driven parachute capsules are expensive and dangerous, and are usually used for fixed-wing drones. The drones themselves are not heavy, and gravity is not enough to pull out the main parachute. When opening the parachute, high-pressure gas is used to push the parachute as high as possible to keep it away from the propeller to prevent entanglement. Ocean observation equipment has no propellers and most of them have a certain weight (usually ranging from 20 to 50 kg). When opening the parachute, it is usually only necessary to eject the guide parachute from the parachute capsule. After the guide parachute is deployed, the resistance of the guide parachute and the gravity of the observation equipment are enough to pull out the main parachute. Therefore, airdrop parachutes for ocean observation equipment are not suitable for gas-driven opening.

[0005] Spring-pull automatic parachute deployment mechanisms typically utilize the spring force of the guide parachute and the hatch torsion spring to deploy the parachute. The canopy is typically opened and closed by a motor (servo) driving a latch. The motor pulls out the latch, automatically opening the canopy. After closing the canopy, the motor rotates to insert the latch, retracting the parachute. This mechanism deactivates the motor to release the latch, requiring another motor action after the canopy automatically opens to retract the parachute. This makes parachutes easy to deploy but difficult to retract, reducing deployment efficiency when used for airdropping ocean observation equipment.

[0006] Therefore, how to provide a parachute automatic opening device based on titanium wire electric control lock suitable for deploying ocean observation equipment is a technical problem that urgently needs to be solved. Utility Model Content

[0007] In response to the shortcomings of the existing technology, the utility model provides an automatic parachute opening device based on a titanium wire electric-controlled lock, which controls the opening or closing of the parachute cover through the titanium wire electric-controlled lock, providing a more efficient, safe and economical solution for the airdrop deployment of ocean observation equipment.

[0008] The utility model provides a parachute automatic opening device based on a titanium wire electric-controlled lock, comprising:

[0009] Main parachute;

[0010] guide parachute;

[0011] The parachute cabin includes a cabin body, a parachute cabin cover, and a stacking seat, and is used to store the main parachute and the pilot parachute. The cabin body is hinged to the parachute cabin cover, and the cabin body is fixedly connected to the stacking seat. The main parachute is installed on the stacking seat, and the pilot parachute is stored above the main parachute.

[0012] The titanium wire electric lock is fixed to one end of the cabin body close to the parachute cover and is movably connected to the parachute cover to control the opening or closing of the parachute cover. When the titanium wire electric lock is opened, the parachute cover and the titanium wire electric lock are released from the constraints, the guide parachute automatically pops out and pulls the main parachute to unfold.

[0013] This technical solution controls the opening or closing of the parachute canopy through a titanium wire electric lock, providing a more efficient, safe and economical solution for the airdrop deployment of ocean observation equipment.

[0014] In some embodiments, the titanium wire electric lock's lock buckle is fixedly connected to the umbrella canopy, while the titanium wire electric lock's lock tongue is movably connected to the lock buckle. When the titanium wire electric lock is opened, the lock tongue retracts and releases the lock buckle, causing the umbrella canopy to automatically spring open. This technical solution simplifies the operation process of opening and closing the umbrella through a simple structure, which can improve the device's response speed.

[0015] In some embodiments, the lock is connected to the umbrella cover with bolts. In this technical solution, the lock is connected to the umbrella cover by bolts, forming a strong connection between the lock and the umbrella cover, ensuring a tight fit of the umbrella cover in the closed state.

[0016] In some embodiments, first pads are provided on both the inner and outer sides of the connection between the titanium wire electric lock and the cabin. The first pads include a first outer pad and a first inner pad. The inner surface of the first outer pad mates with the outer surface of the cabin, while the outer surface of the first inner pad mates with the inner surface of the cabin. This technical solution ensures a secure connection and good sealing between the lock body and the cabin by designing the pads on both sides of the connection between the titanium wire electric lock and the cabin.

[0017] In some embodiments, a torsion spring hinge is installed at the hinged connection between the cabin and the canopy; when the canopy is closed, the torsion spring hinge is in the closed position. This technical solution uses the preload of the torsion spring hinge to provide elastic force during parachute deployment, helping the canopy to open quickly and ensuring the parachute is released quickly.

[0018] In some embodiments, a second pad is provided at the connection between the torsion spring hinge and the cabin. The second pad includes a second outer pad and a second inner pad. The inner surface of the second outer pad mates with the outer surface of the cabin, while the outer surface of the second inner pad mates with the inner surface of the cabin. This technical solution ensures a tight fit and stability between the torsion spring hinge and the cabin through the provision of the second pad, while also providing additional cushioning to reduce the impact of vibration and shock on the device.

[0019] In some embodiments, the pilot parachute is equipped with a spring, mounted between the pilot parachute and the main parachute. When the canopy is closed, the spring is compressed. This technical solution utilizes the spring to rapidly release its force when the canopy is opened, thereby rapidly ejecting the pilot parachute and deploying the main parachute, effectively improving the parachute system's responsiveness and airdrop deployment efficiency.

[0020] In some embodiments, the cabin and the folding seat are fixedly connected by screws. The technical solution uses screw connection structure to be stable and reliable, which not only enhances the structural strength of the entire parachute system.

[0021] In some embodiments, a cylindrical wedge is provided around the outer periphery of the screw for reinforcement. This technical solution improves the structural reliability of the entire parachute system through the reinforcement of the cylindrical wedge, and helps prevent the screw from loosening under severe vibration or impact.

[0022] In some embodiments, there are multiple screws, and the multiple screws are evenly distributed on the periphery of the folding umbrella base. This technical solution ensures uniform force and stable connection between the folding umbrella base and the cabin by evenly arranging multiple screws on the periphery of the folding umbrella base.

[0023] Based on the above scheme, the automatic parachute opening device based on the titanium wire electric lock in the embodiment of the present invention restrains the parachute cover through the titanium wire electric lock. When the titanium wire electric lock is opened, the parachute cover and the titanium wire electric lock are released from the restraint, the guide parachute automatically pops out, and under the action of the air resistance of the guide parachute and the gravity of the observation equipment, the main parachute is pulled out and unfolded to complete the parachute opening; opening the parachute through the titanium wire electric lock can make the parachute cover open quickly, and the guide parachute and the main parachute can be quickly unfolded, thereby shortening the airdrop deployment time; at the same time, compared with gas-driven parachute opening, the titanium wire electric lock unlocking parachute opening device provided by the utility model can avoid the use of high-pressure gas, reducing costs and potential safety risks. It should also be noted that the automatic parachute opening device based on the titanium wire electric control lock in this embodiment, when folding the parachute, stores the guide parachute in the parachute cabin, closes the parachute cabin cover and presses it down hard, so that the titanium wire electric control lock and the parachute cabin cover are locked and constrained, and the parachute can be folded. Compared with the conventional spring-pushing parachute opening device, the present invention controls the opening or closing of the parachute cabin cover through the titanium wire electric control lock. When folding the parachute, just press the parachute cabin cover down, and there is no need to send instructions to the titanium wire electric control lock. This can simplify the parachute folding steps and improve the efficiency of airdrop deployment. In summary, the automatic parachute opening device based on the titanium wire electric control lock in the embodiment of the present invention provides a more efficient, safe and economical solution for the airdrop deployment of ocean observation equipment.

[0038] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0041] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can 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 these terms in this utility model based on the specific circumstances.

[0042] The terms "system", "unit" and "module" used in this document are a method for distinguishing different components, elements, parts, portions or assemblies at different levels, and these terms may be replaced by other expressions that can achieve the same purpose.

[0043] like Figure 1-Figure 7 As shown, in one embodiment of the parachute automatic opening device based on the titanium wire electric lock of the present invention, the parachute automatic opening device based on the titanium wire electric lock includes a main parachute 1, a guide parachute 2, a parachute cabin 3 and a titanium wire electric lock 4; wherein, the parachute cabin 3 includes a cabin body 301, a parachute cabin cover 302 and a folding parachute seat 303, which is used to store the main parachute 1 and the guide parachute 2; the cabin body 301 is hinged to the parachute cabin cover 302, and the cabin body 301 is fixedly connected to the folding parachute seat 303, the main parachute 1 is installed on the folding parachute seat 303, and the guide parachute 2 is stored above the main parachute 1; the titanium wire electric lock 4 is fixed to one end of the cabin body 301 close to the parachute cabin cover 302, and is movably connected to the parachute cabin cover 302, for controlling the opening or closing of the parachute cabin cover 302; when the titanium wire electric lock 4 is opened, the parachute cabin cover 302 and the titanium wire electric lock 4 are released from the constraints, the guide parachute 2 automatically pops out and pulls the main parachute 1 to unfold.

[0044] In the above-mentioned schematic embodiment, the automatic parachute opening device based on the titanium wire electric lock restrains the parachute cover 302 through the titanium wire electric lock 4. When the titanium wire electric lock 4 is opened, the parachute cover 302 and the titanium wire electric lock 4 are released from the restraint, the guide parachute 2 automatically pops out, and under the action of the air resistance of the guide parachute 2 and the gravity of the observation equipment, the main parachute 1 is pulled out and unfolded to complete the parachute opening; opening the parachute through the titanium wire electric lock 4 can quickly open the parachute cover 302, and the guide parachute 2 and the main parachute 1 can be quickly unfolded, thereby shortening the airdrop deployment time; at the same time, compared with the gas-driven parachute opening, the device for unlocking the parachute with the titanium wire electric lock 4 provided by the utility model can avoid the use of high-pressure gas, reduce costs and potential safety risks. It should also be noted that the automatic parachute opening device based on the titanium wire electric control lock in this embodiment, when folding the parachute, after the guide parachute 2 is stored in the parachute compartment 3, the parachute compartment cover 302 is closed and pressed down with force, so that the titanium wire electric control lock 4 and the parachute compartment cover 302 are locked and constrained, and the parachute can be folded. Compared with the conventional spring 8 push-out parachute opening device, the present invention controls the opening or closing of the parachute compartment cover 302 through the titanium wire electric control lock 4. When folding the parachute, the parachute compartment cover 302 can be pressed down without sending instructions to the titanium wire electric control lock 4. This can simplify the folding steps and improve the efficiency of airdrop deployment. In summary, the automatic parachute opening device based on the titanium wire electric control lock in the embodiment of the present invention provides a more efficient, safe and economical solution for the airdrop deployment of ocean observation equipment.

[0045] In some embodiments, as Figure 1 As shown, the lock buckle 402 of the titanium wire electric lock 4 is fixedly connected to the umbrella cabin cover 302, and the lock tongue 401 of the titanium wire electric lock 4 is movably connected to the lock buckle 402. When the titanium wire electric lock 4 is opened, the lock tongue 401 is retracted and released from the lock buckle 402, and the umbrella cabin cover 302 automatically pops open. By fixing the lock buckle 402 of the titanium wire electric lock 4 to the umbrella cabin cover 302, as shown in FIG. Figure 6-Figure 7 As shown, when opening the umbrella, the constraints of the lock tongue 401 and the lock buckle 402 of the titanium wire electric lock 4 are released, and the umbrella cover 302 can be automatically opened; when closing the umbrella, the umbrella cover 302 is pressed down hard to lock the lock tongue 401 and the lock buckle 402 of the titanium wire electric lock 4, and the umbrella is closed; the simple structure simplifies the operation process of opening and closing the umbrella, and can improve the response speed of the device.

[0046] Furthermore, the lock buckle 402 is bolted to the umbrella cover 302. Through the bolt connection, a strong connection is formed between the lock buckle 402 and the umbrella cover 302, ensuring that the umbrella cover 302 fits tightly when closed; in addition, the bolt connection facilitates disassembly and replacement, making maintenance work easier.

[0047] In some embodiments, as Figure 1As shown, first pads 5 are installed on both the inner and outer sides of the connection between the titanium wire electric lock 4 and the cabin 301. These pads 5 include a first outer pad 501 and a first inner pad 701502. The inner surface of the first outer pad 501 mates with the outer surface of the cabin 301, while the outer surface of the first inner pad 701502 mates with the inner surface of the cabin 301. The double-sided pad design at the connection between the titanium wire electric lock 4 and the cabin 301 ensures a secure connection and a good seal between the lock body and the cabin 301. The mutual fit of the first outer pad 501 and the first inner pad 701502 not only enhances the structural integrity and durability, but also helps absorb the vibration and impact that may occur during the airdrop process, thereby improving the reliability and safety of the parachute system. Furthermore, it facilitates the rapid replacement or repair of the electric lock when needed, improving maintenance efficiency.

[0048] In some embodiments, as Figure 1 As shown, a torsion spring hinge 6 is installed at the hinged joint between the cabin 301 and the parachute cover 302. When the parachute cover 302 is closed, the torsion spring hinge 6 is in the closed position. The preload of the torsion spring hinge 6 provides elastic force during parachute deployment, helping the parachute cover 302 to open quickly and ensuring the rapid release of the parachute. This not only improves the efficiency of airdrop deployment but also enhances the reliability of the entire system.

[0049] In some embodiments, as Figure 1 As shown, second pads 7 are provided at the connection between the torsion spring hinge 6 and the cabin 301. These second pads 7 include a second outer pad and a second inner pad 702. The inner surface of the second outer pad mates with the outer surface of the cabin 301, while the outer surface of the second inner pad 702 mates with the inner surface of the cabin 301. The provision of second pads 7 ensures a tight fit and stability between the torsion spring hinge 6 and the cabin 301, while also providing additional cushioning, reducing the effects of vibration and shock on the equipment and enhancing the durability and reliability of the entire structure. Furthermore, maintenance and replacement of the torsion spring hinge 6 become more convenient and quicker.

[0050] In some embodiments, as Figure 1 As shown, the pilot parachute 2 is provided with a spring 8, which is installed between the pilot parachute 2 and the main parachute 1. When the parachute canopy 302 is closed, the spring 8 is compressed. By configuring the spring 8, the elastic force of the spring 8 is quickly released when the parachute canopy 302 is opened, thereby pushing the pilot parachute 2 to quickly pop out and drive the main parachute 1 to deploy. This effectively improves the parachute system's response speed and airdrop deployment efficiency, while also reducing mechanical complexity and potential failure points, enhancing the reliability of the entire system and simplifying operation.

[0051] In some embodiments, as Figure 1As shown, the cabin 301 and the folding seat 303 are fixedly connected by screws 9. The screw connection structure 9 is stable and reliable, which not only enhances the structural strength of the entire parachute system, but also facilitates rapid disassembly and maintenance when needed. In addition, the reversibility of the screw connection means that it can be repeatedly assembled and disassembled without damage, thereby improving the maintenance efficiency and service life of the equipment, while also ensuring the stability and safety of the parachute system in extreme environments.

[0052] In some embodiments, as Figure 1 As shown, a cylindrical wedge 10 is provided around the outer periphery of the screw 9 for reinforcement. The reinforcement of the cylindrical wedge 10 improves the structural reliability of the entire parachute system, helps prevent the screw 9 from loosening under severe vibration or impact, and ensures the safety of the ocean observation equipment during the airdrop process.

[0053] In some embodiments, multiple screws 9 are provided, and the multiple screws 9 are evenly distributed around the periphery of the folding umbrella base 303. By evenly arranging multiple screws 9 around the periphery of the folding umbrella base 303, uniform force and stable connection between the folding umbrella base 303 and the cabin 301 are ensured.

[0054] In some embodiments, the automatic parachute deployment device based on the titanium wire electric lock further includes a controller, which is in communication with the titanium wire electric lock 4 and is configured to send an unlocking signal to the titanium wire electric lock 4 to control the opening of the titanium wire electric lock 4. The controller ensures the timely opening of the parachute canopy 302 and the rapid deployment of the parachute. This intelligent automatic control method greatly improves the efficiency and safety of airdrop deployment while also reducing the complexity and error rate of manual operation.

[0055] Furthermore, the controller is equipped with an accelerometer to detect whether the parachute is in a weightless state. When the parachute is in a weightless state, the controller sends an unlocking signal to the titanium wire electronic lock 4. By integrating the accelerometer into the controller, the controller intelligently detects whether the parachute is in a weightless state and automatically sends an unlocking signal to the titanium wire electronic lock 4 at the appropriate time, thereby quickly opening the parachute canopy 302 and releasing the parachute. This not only improves the accuracy and efficiency of airdrop deployment, but also enhances operational safety, reduces reliance on human intervention, and makes the entire airdrop process more reliable and efficient.

[0056] The specific structure and working process of an embodiment of the parachute automatic opening device based on the titanium wire electric control lock of the utility model are described below:

[0057] (1) Parachute opening process

[0058] When the acceleration sensor detects that the parachute is in a weightless state, the controller sends an unlocking signal to the titanium wire electric control lock 4; after the titanium wire electric control lock 4 receives the unlocking signal, Figure 1As shown, the lock tongue 401 and the lock buckle 402 of the titanium wire electric lock 4 are released, the titanium wire electric lock 4 is opened, and the umbrella cover 302 automatically pops open under the elastic force of the torsion spring hinge 6; the spring 8 quickly releases the elastic force when the umbrella cover 302 is opened, pushing the guide parachute 2 to pop out quickly and drive the main parachute 1 to unfold, realizing automatic umbrella opening.

[0059] (2) Umbrella folding process

[0060] like Figure 1 As shown, the main parachute 1 and the guide parachute 2 are stored in the parachute compartment 3 in sequence, and the guide parachute 2 is pressed down to compress the spring 8; while closing the parachute compartment cover 302, press down hard to lock the lock tongue 401 and the lock buckle 402 of the titanium wire electric lock 4 to close the parachute compartment cover 302 and complete the folding of the parachute.

[0061] Through the description of multiple embodiments of the automatic parachute opening device based on titanium wire electric control lock of the present invention, it can be seen that the embodiments of the automatic parachute opening device based on titanium wire electric control lock of the present invention have at least one or more of the following advantages:

[0062] 1.

[0063] 2.

[0065] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0066] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for which protection is requested in the present invention.
