Abstract
Description
Technical Field
[0001] This application relates to the field of drone accessory design and manufacturing technology, specifically a reusable drone airbag compartment. Background Technology
[0002] In recent years, with the rapid development of drone technology, it has been widely used in aerial photography, logistics transportation, agricultural plant protection and other fields. However, in actual operation, due to the complex and changeable flight environment, drones often encounter sudden situations that lead to emergency landings. This may not only cause equipment damage, but also affect the efficiency of mission completion and even bring safety hazards.
[0003] An existing patent (publication number: CN219406903U) discloses a drone anti-sinking device. The anti-sinking device includes an anti-sinking device body, an air cylinder, a triggering component, and a striker component. The anti-sinking device body has a ventilation chamber, and a first through hole, a second through hole, and an air guide nozzle connected to the ventilation chamber. The air guide nozzle is used to connect to the air bag. The air cylinder is installed at the first through hole, the triggering component is installed at the second through hole, and the striker component is installed in the ventilation chamber. One end of the striker component corresponds to the opening of the air cylinder, and the other end of the striker component corresponds to one end of the triggering component. By using the triggering component to act on the striker component, the striker component punctures the air cylinder, and the air cylinder inflates the air bag, causing the drone to float on the water surface, thus facilitating retrieval.
[0004] However, in actual use, airbags are usually used to absorb impact energy to reduce damage to the body. However, traditional airbags have the problem of not being reusable. Airbags are prone to rupture, or their performance deteriorates after multiple inflation and deflation cycles. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a reusable UAV airbag compartment, which has the advantages that both the airbag compartment body and the airbag body can be reused. This solves the problems of traditional airbags being unable to be reused, being easily damaged, or having their performance degraded after multiple inflation and deflation cycles.
[0006] To achieve the above objectives, this application provides the following technical solution: a reusable drone airbag housing, comprising an airbag housing body, the outer surface of which is hardened, and an airbag body installed on the inner wall of which the airbag housing body is located. The airbag body comprises an outer layer, a middle layer, and an inner layer. The outer layer comprises a fiber layer, the material of which is nylon, the material of which is glass fiber, the material of which is nitrile rubber, and the material of which is thermoplastic polyurethane.
[0007] Through the above scheme, in order to achieve the reusability of the airbag chamber and airbag body, a hardening treatment is applied to the outer surface of the airbag chamber to enhance its wear resistance, impact resistance, and corrosion resistance. This reduces wear and allows for reuse. The airbag body adopts a three-layer design: an outer layer made of nylon with an inner fiber layer made of glass fiber to withstand stronger impacts. The reinforced nylon layer effectively prevents damage to the airbag body. The middle layer is made of nitrile rubber, which prevents harmful substances from penetrating the outer layer and entering the airbag body, thus protecting the overall performance of the airbag. The elasticity of the nitrile rubber also provides cushioning, working in conjunction with the inner layer. The inner layer is made of thermoplastic polyurethane, ensuring the stability of the airbag body during inflation and deflation. This ensures stable performance across multiple inflation and deflation cycles, enhancing durability and reliability, extending service life, and enabling both the airbag chamber and airbag body to be reused.
[0008] Furthermore, a drone body is located above the airbag compartment, and a frame is fixedly installed on the bottom surface of the drone body. Two connecting rods are fixedly installed on the inner wall of the frame.
[0009] The above solution places the main body of the drone above the airbag chamber. The main body of the drone is an existing component, consisting of a shell, tail fin, side wings, propellers, and drive components, enabling the main body of the drone to take off, move, and land. The frame is installed on the bottom of the main body of the drone, and the connecting rod is installed on the inner wall of the frame. The frame and connecting rod provide support for the main body of the drone after landing.
[0010] Furthermore, a trigger module is fixedly installed on the bottom surface of the frame, and a gas cylinder is fixedly connected to the right side of the trigger module.
[0011] The above solution involves placing the trigger module on the bottom of the frame. The trigger module is an existing component that can detect whether the airbag needs to be opened during the descent or movement of the drone body. The gas cylinder is connected to the trigger module. When the trigger module is activated, the gas inside the gas cylinder can be transmitted to the airbag body to open it.
[0012] Furthermore, a connecting pipe is fixedly installed on the bottom surface of the trigger module, the outer surface of the connecting pipe is fixedly connected to the inner wall of the airbag body, and the bottom end of the connecting pipe is fixedly connected to the interior of the airbag body.
[0013] The above solution involves installing the connecting tube on the bottom surface of the trigger module. The connecting tube facilitates the transmission of gas from the gas cylinder. The outer surface of the connecting tube is connected to the main body of the airbag to limit its movement. The bottom end of the connecting tube is connected to the inside of the airbag, allowing gas to quickly fill the airbag.
[0014] Furthermore, the outer surface of the gas cylinder is provided with two limiting frames, and the inner wall of each limiting frame is fixedly installed with two bolts, and the outer surface of each bolt is fixedly installed with the inner wall of the frame.
[0015] The above method involves placing the limit frame on the outer surface of the gas cylinder and installing bolts on the inner wall of the corresponding limit frame. The limit frame is then connected to the frame via the bolts, thus enabling the installation of the gas cylinder.
[0016] Furthermore, each of the limiting frames has two mounting rods fixedly connected to its outer surface, and the bottom end of each mounting rod is fixedly connected to the upper surface of the airbag chamber body.
[0017] By fixing the mounting rod to the outer surface of the limiting frame and connecting the bottom end of the mounting rod to the upper surface of the airbag compartment body, the stability of the airbag compartment body after installation can be improved.
[0018] Furthermore, an air extraction tube is fixedly connected to the outer surface of the airbag body, a solenoid valve is fixedly installed on the outer surface of the air extraction tube, and a miniature air extraction pump is fixedly installed at the other end of the air extraction tube.
[0019] The above scheme involves installing a suction tube on the outer surface of the airbag body and connecting them. The suction tube facilitates the discharge of gas from inside the airbag body. A solenoid valve is installed on the outer surface of the suction tube, which controls the closure of the suction tube. A miniature suction pump is connected to the suction tube. Through the cooperation of the miniature suction pump and the suction tube, gas inside the airbag body can be extracted.
[0020] Furthermore, an exhaust pipe is fixedly installed at the output end of the micro air pump, and the bottom surface of the micro air pump is fixedly connected to the upper surface of the airbag chamber body.
[0021] The above solution involves installing the exhaust pipe at the output end of the miniature air pump, allowing gas to be discharged quickly. The bottom surface of the miniature air pump is connected to the upper surface of the airbag body in a fixed connection, thus enabling the installation of the miniature air pump. Through the air extraction pipe, the miniature air pump, and the exhaust pipe, the gas inside the airbag body can be quickly extracted, allowing for more thorough deflation and preventing gas residue inside the airbag body.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] This reusable drone airbag compartment, through the design of the airbag compartment body and other components, features a hardened airbag compartment body to enhance its wear resistance, impact resistance, and corrosion resistance, thereby reducing wear. It employs a nylon outer layer with an internal fiber layer of glass fiber, a nitrile rubber middle layer, and a thermoplastic polyurethane inner layer to ensure stable performance during multiple inflation and deflation cycles, enhancing durability and reliability, extending service life, and achieving reusability. The inclusion of an air extraction pipe, solenoid valve, micro air pump, and exhaust pipe allows for rapid gas discharge from the airbag body, preventing gas residue inside.

[0040] This embodiment presents a reusable drone airbag compartment. By setting up components such as an airbag compartment body 1 and an airbag body 2, the airbag compartment body 1 is hardened to enhance its wear resistance, impact resistance, and corrosion resistance, thereby reducing wear. It adopts an outer layer 201 made of nylon and adds a fiber layer 2011 made of glass fiber inside it. It adopts an intermediate layer 202 made of nitrile rubber and an inner layer 203 made of thermoplastic polyurethane to ensure that the airbag body 2 can maintain stable performance in multiple inflation and deflation cycles, enhancing durability and reliability, extending service life, and achieving the effect of reuse. The air extraction pipe 12, solenoid valve 13, micro air extraction pump 14, and exhaust pipe 15 are set up to allow the gas inside the airbag body 2 to be quickly discharged, preventing gas residue inside the airbag body 2.
[0041] It should be noted that the main body 3 of the drone and the trigger module 6 are existing components, and their internal structures will not be described in detail here.
[0042] The working principle of the above embodiments is as follows:
[0043] When the drone body 3 descends or encounters an emergency, the trigger module 6 causes the gas cylinder 7 to discharge gas, which is then transmitted to the airbag body 2 through the connecting pipe 8, causing the airbag body 2 to inflate rapidly. Because the exterior of the airbag body 1 is hardened and the airbag body 2 is configured with an outer, middle, and inner layer, using a nylon outer layer 201, a glass fiber layer 2011 inside, a nitrile rubber middle layer 202, and a thermoplastic polyurethane inner layer 203, the airbag body 2 can maintain stable performance during multiple inflation and deflation cycles, enhancing the durability and reliability of the airbag body 2, extending its service life, and achieving the effect that both the airbag body 1 and the airbag body 2 can be reused. When deflation is required, the solenoid valve 13 is opened, and the micro air pump 14 is started. The gas inside the airbag body 2 is extracted through the air extraction pipe 12 and then discharged through the exhaust pipe 15, allowing the gas inside the airbag body 2 to be discharged quickly and preventing gas residue inside the airbag body 2.
