Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV with an emergency self-rescue mechanism. Background Technology

[0002] Drones are a general term for unmanned aerial vehicles. The characteristic of drones is that they have no cockpit. In existing drone designs, the parachute self-rescue system is an important safety device that can provide emergency landing when the drone is out of control or malfunctions, protecting the drone and its carried equipment from damage.

[0003] The parachute self-rescue system consists of a parachute compartment and a parachute body. In case of an emergency, the parachute compartment can eject the parachute body to achieve an emergency landing. However, existing parachute compartments are usually fixed to the drone with straps. This fixing method is prone to insecure installation. In this case, the huge impact force of the parachute compartment ejecting the parachute body can easily damage the drone, greatly reducing the safety of drone use. Utility Model Content

[0004] The purpose of this invention is to provide a drone with an emergency self-rescue mechanism to solve the problem mentioned in the background art, where the parachute compartment is usually fixed to the drone with straps. This fixing method is prone to insecure installation. In this case, the huge impact force of the parachute compartment popping out the parachute body can easily damage the drone, greatly reducing the safety of drone use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drone with an emergency self-rescue mechanism, comprising a drone body, a self-rescue mechanism provided on the surface of the drone body, the self-rescue mechanism including a positioning frame, the positioning frame fixedly connected to the surface of the drone body, a buffer pad fixedly connected to the surface of the drone body, a parachute compartment engaged with the inner side of the positioning frame, and the bottom of the parachute compartment in contact with the buffer pad, a limit block fixedly connected to the surface of the parachute compartment, a guide rod fixedly connected to the surface of the positioning frame, a first spring fixedly connected to the surface of the guide rod, a first limiting rod fixedly connected to the surface of the first spring, an operating block fixedly connected to the surface of the first limiting rod, the first limiting rod and the operating block slidably connected to the surface of the guide rod, and a parachute body provided at the top of the positioning frame.

[0006] Preferably, the bottom of the drone body is provided with a landing mechanism, the landing mechanism includes a mounting rail, the mounting rail is fixedly connected to the bottom of the drone body, a mounting slide rod is slidably connected to the surface of the mounting rail, a landing gear is fixedly connected to the bottom of the mounting slide rod, a limit frame is fixedly connected to the bottom of the mounting rail, a second spring is fixedly connected to the surface of the limit frame, a second limit rod is fixedly connected to the surface of the second spring, and the second limit rod is slidably connected to the surface of the limit frame.

[0007] Preferably, the bottom area of ​​the parachute compartment is the same as the surface area of ​​the cushioning pad, and the positioning frame completely restricts the bottom of the parachute compartment to the surface of the cushioning pad, which is made of polyurethane foam.

[0008] Preferably, when a guide groove is formed on the surface of the guide rod and a guide hole is formed on one side of the guide groove, the first limiting rod slides on the guide groove of the guide rod and the operating block slides on the guide hole of the guide rod.

[0009] Preferably, a limiting hole is formed on the surface of the limiting block, the first spring is located on the guide groove of the guide rod, and the first spring causes the first limiting rod to slide into the limiting hole of the limiting block through its elastic force.

[0010] Preferably, the surface of the mounting rail is provided with a guide hole, and the guide hole is in the shape of a "T". The mounting slide rod slides in the guide hole of the mounting rail in the shape of a "T".

[0011] Preferably, a limiting groove is provided at the bottom of the mounting slide rod, the limiting frame is in the shape of an "L", the elastic force of the second spring acts on the second limiting rod, and the second limiting rod is inserted into the limiting groove at the bottom of the mounting slide rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This drone uses a positioning frame to position the parachute compartment on the surface of the buffer pad. At this time, the limiting hole of the limiting block aligns with the guide groove of the guide rod. The elastic force of the first spring causes the first limiting rod to slide on the guide groove of the guide rod, so that the first limiting rod is inserted into the limiting hole of the limiting block. The first limiting rod restricts the limiting block on the guide rod, thereby realizing the installation of the parachute compartment on the drone body. This avoids the phenomenon of loosening when the parachute compartment is installed on the top of the drone body. Furthermore, when the parachute body is ejected from the parachute compartment, it is cushioned by the buffer pad at the bottom of the drone body, thereby avoiding damage to the drone body and improving the safety of drone use.

[0014] 2. The UAV slides the mounting rod into the guide hole of the mounting rail until the mounting rod drives the landing gear to slide and contact the surface of the limiting frame. At this time, the mounting rail is fully slid into the guide hole of the mounting rail, and the second limiting rod is aligned with the limiting groove at the bottom of the mounting rod. The elastic force of the second spring acts on the second limiting rod, so that the second limiting rod is inserted into the limiting groove at the bottom of the mounting rod. The first spring restricts the position of the mounting rod on the mounting rail, thereby realizing the installation of the landing gear at the bottom of the mounting rod. The disassembly principle is the same, which facilitates the replacement of the landing gear on the UAV body and greatly improves the convenience of landing gear maintenance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6One embodiment provided by this utility model:

[0024] A drone with an emergency self-rescue mechanism includes a drone body 1. A self-rescue mechanism is provided on the surface of the drone body 1. The self-rescue mechanism includes a positioning frame 2, which is fixedly connected to the surface of the drone body 1. The connection between the positioning frame 2 and the drone body 1 is achieved using laser welding. A buffer pad 21 is fixedly connected to the surface of the drone body 1. A parachute compartment 22 is engaged with the inner side of the positioning frame 2, and the bottom of the parachute compartment 22 contacts the buffer pad 21. A limit block 23 is fixedly connected to the surface of the parachute compartment 22. A guide rod 24 is fixedly connected to the surface of the positioning frame 2. A first spring 25 is fixedly connected to the surface of the guide rod 24. A [missing information - likely a device or mechanism] is fixedly connected to the surface of the first spring 25. The first limiting rod 26 has an operating block 27 fixedly connected to its surface. The first limiting rod 26 and the operating block 27 are slidably connected to the surface of the guide rod 24. The top of the positioning frame 2 is provided with a parachute body 28, which is made of high-strength nylon fabric. The parachute compartment 22 is equipped with a triggering device. When the drone malfunctions, the automatic ejection mechanism is triggered, causing the parachute body 28 to be ejected. This self-rescue mechanism avoids using straps to fix the parachute compartment 22, and instead adopts a more secure fixing method. At the same time, a buffer pad 21 is used for cushioning, thereby preventing the impact on the parachute compartment 22 from damaging the drone body 1 and ensuring the safety of the self-rescue mechanism of the drone body 1.

[0025] Furthermore, a landing mechanism is provided at the bottom of the UAV body 1. The landing mechanism includes a mounting rail 3, which is fixedly connected to the bottom of the UAV body 1. A mounting slide rod 31 is slidably connected to the surface of the mounting rail 3. A landing gear 32 is fixedly connected to the bottom of the mounting slide rod 31. A limit frame 33 is fixedly connected to the bottom of the mounting rail 3. A second spring 34 is fixedly connected to the surface of the limit frame 33. A second limit rod 35 is fixedly connected to the surface of the second spring 34. The second limit rod 35 is slidably connected to the surface of the limit frame 33. This landing mechanism enables the landing gear 32 to be quickly replaced, greatly improving the convenience of maintaining the landing gear 32.

[0026] Furthermore, the bottom area of ​​the parachute compartment 22 is the same as the surface area of ​​the cushioning pad 21. The positioning frame 2 completely restricts the bottom of the parachute compartment 22 to the surface of the cushioning pad 21. The cushioning pad 21 is made of polyurethane foam. The cushioning pad 21 can effectively cushion the parachute compartment 22. The cushioning pad 21 is durable, can withstand multiple impacts, and is lightweight and low in cost, making it suitable for various environments and conditions.

[0027] Furthermore, a guide groove is provided on the surface of the guide rod 24, and a guide hole is provided on one side of the guide groove. The first limiting rod 26 slides on the guide groove of the guide rod 24, and the operating block 27 slides on the guide hole of the guide rod 24. The operating block 27 protrudes from the surface of the guide rod 24 to facilitate user operation. By operating the operating block 27 on the surface of the guide rod 24, the first limiting rod 26 can be driven to slide on the guide groove of the guide rod 24.

[0028] Furthermore, a limiting hole is formed on the surface of the limiting block 23, the bottom of the limiting block 23 is in contact with the positioning frame 2, and the side of the limiting block 23 is in contact with the guide rod 24. The first spring 25 is located on the guide groove of the guide rod 24. The first spring 25 causes the first limiting rod 26 to slide into the limiting hole of the limiting block 23 through the elastic force. The first limiting rod 26 restricts the position of the parachute compartment 22 on the positioning frame 2 and the buffer pad 21 through the limiting block 23, thereby realizing the positioning of the parachute compartment 22 on the UAV body 1. Its installation method is more reliable and avoids the problem of easy loosening of the strap installation.

[0029] Furthermore, a guide hole is provided on the surface of the mounting rail 3, and the guide hole is in the shape of a "T". The mounting slide rod 31 slides in the guide hole of the mounting rail 3 in the shape of a "T". The UAV body 1 can support the mounting slide rod 31 through the mounting rail 3, and the mounting slide rod 31 can support the landing gear 32, thereby facilitating the installation of the landing gear 32. The limiting frame 33 restricts the extreme position of the mounting slide rod 31 sliding on the mounting rail 3 at the bottom of the mounting slide rod 31. The mounting slide rod 31 and the mounting rail 3 have the same length. When the mounting slide rod 31 slides completely to the guide hole of the mounting rail 3, the limiting frame 33 restricts the mounting slide rod 31 from continuing to slide, thereby positioning the landing gear 32 at the installation position at the bottom of the mounting slide rod 31.

[0030] Furthermore, a limiting groove is provided at the bottom of the mounting slide bar 31, and the limiting frame 33 is in an "L" shape. The elastic force of the second spring 34 acts on the second limiting rod 35. The second limiting rod 35 is inserted into the limiting groove at the bottom of the mounting slide bar 31. When the mounting slide bar 31 cannot slide on the mounting guide rail 3, the second limiting rod 35 is aligned with the limiting groove at the bottom of the mounting slide bar 31, and the second limiting rod 35 can be quickly inserted into the limiting groove of the mounting slide bar 31, thereby limiting the mounting slide bar 31 on the mounting guide rail 3. The mounting slide bar 31 also restricts the position of the landing gear 32 at the bottom of the UAV body 1, thus completing the installation of the landing gear 32.

[0031] Working principle: The parachute compartment 22 is positioned on the surface of the buffer pad 21 by the positioning frame 2. At this time, the limiting hole of the limiting block 23 is aligned with the guide groove of the guide rod 24. The elastic force of the first spring 25 causes the first limiting rod 26 to slide on the guide groove of the guide rod 24, so that the first limiting rod 26 is inserted into the limiting hole of the limiting block 23. The first limiting rod 26 restricts the limiting block 23 on the guide rod 24, thereby realizing the installation of the parachute compartment 22 on the drone body 1. This avoids the phenomenon of the parachute compartment 22 being loose when installed on the top of the drone body 1. When the parachute body 28 is ejected from the parachute compartment 22, it is cushioned by the buffer pad 21 at the bottom of the drone body 1, thereby avoiding damage to the drone body 1 and improving the safety of drone use.

[0032] The mounting slide bar 31 is slid into the guide hole of the mounting rail 3 until the mounting slide bar 31 drives the landing gear 32 to slide and contact the surface of the limiting frame 33. At this time, the mounting rail 3 is fully slid into the guide hole of the mounting rail 3. The second limiting rod 35 is aligned with the limiting groove at the bottom of the mounting slide bar 31. The elastic force of the second spring 34 acts on the second limiting rod 35, so that the second limiting rod 35 is inserted into the limiting groove at the bottom of the mounting slide bar 31. The first spring 25 restricts the position of the mounting slide bar 31 on the mounting rail 3, thereby realizing the installation of the landing gear 32 at the bottom of the mounting slide bar 31. The disassembly principle is the same, which makes it convenient to replace the landing gear 32 on the UAV body 1 and greatly improves the convenience of maintenance of the landing gear 32.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
