Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicles (UAVs), and more specifically, to a UAV landing gear protection structure. Background Technology

[0002] The landing gear of a drone is a critical component that comes into direct contact with the ground during takeoff, landing, and parking. Its main functions are to support the drone's body, absorb the impact of landing, and protect the drone's internal equipment from vibration and impact damage.

[0003] Currently, the mainstream drone tripod design mainly relies on rigid structures. Although the rigid materials themselves have high strength, if the drone lands at too high a speed, the rigid tripod will come into direct contact with the ground, and the tripod will be prone to bending, deformation or breakage. Once the tripod is deformed or broken, the drone body will collide with the ground, causing damage to the drone. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a drone landing gear protection structure, including: a landing gear, a protective airbag, a mounting base, and a pump assembly; the landing gear is used to contact the ground; the mounting base is disposed on the landing gear, and the mounting base has multiple slots for placing the protective airbag, with at least one slot facing the ground; the protective airbag has an air inlet; the pump assembly is disposed on the landing gear, and the output end of the pump assembly is connected to the air inlet, the pump assembly being used to inject gas into the protective airbag.

[0006] Furthermore, the tripod is provided with a first fixing ring; the first fixing ring is provided with a through groove; a locking part is provided between two adjacent locking grooves; the locking part extends toward the through groove; the locking part is engaged and fixed with the through groove.

[0007] Furthermore, on a projection perpendicular to the horizontal plane, the projected area of ​​the first fixing ring is larger than the projected area of ​​the protective airbag before it inflates.

[0008] Furthermore, the extension direction of the slot is parallel to the horizontal plane.

[0009] Furthermore, the protective structure also includes: a second fixing ring, a connecting rod, a third fixing ring, and a fixing bolt; one end of the connecting rod is connected to the second fixing ring, and the other end of the connecting rod is connected to the third fixing ring; the diameter of the second fixing ring is larger than the diameter of the third fixing ring; the mounting base has a protrusion at one end away from the locking part, and the protrusion has an external thread; the second fixing ring is sleeved on the mounting base, and the second fixing ring abuts against the protective airbag; the third fixing ring is sleeved on the protrusion, and when the fixing bolt is threadedly connected to the protrusion, the fixing bolt abuts against the third fixing ring.

[0010] Furthermore, the diameter of the second fixing ring is the same as the diameter of the first fixing ring.

[0011] Furthermore, the protective structure also includes: an air supply pipe and a transition joint; the air supply pipe is mounted on the bracket, and the air supply pipe has a first connection port and a second connection port connected to the pump body assembly; one end of the transition joint is connected to the first connection port, and the other end of the transition joint is connected to the air inlet.

[0013] Furthermore, four card slots are provided.

[0014] Furthermore, both the first fixing ring and the second fixing ring are made of rubber.

[0015] The beneficial effects of this application are as follows:

[0016] When a drone lands at high speed, the pump assembly can inject air into the protective airbag. The protective airbag can make contact with the ground first and absorb the impact force during landing through its own elasticity, thereby reducing the impact force directly borne by the rigid landing gear. This effectively prevents the rigid landing gear from bending, deforming or breaking due to high-speed landing, which could lead to damage to the drone fuselage. Attached Figure Description

[0033] Reference Figure 1-6 ,

[0034] A protective structure for a drone tripod 1 includes: a tripod 1, a protective airbag 2, a mounting base 3, and a pump assembly 4; the pump assembly 4 is a mini air pump or a micro air pump, preferably a micro air pump in this embodiment. The mounting base 3 is made of plastic. A fixed seat is provided on the tripod 1, and the pump assembly 4 is disposed within the fixed seat. The tripod 1 is used to contact the ground; the mounting base 3 is disposed on the tripod 1, and the mounting base 3 has multiple slots 31 for placing the protective airbags 2, with at least one slot 31 facing the ground. In this embodiment, four slots 31 are provided. The multiple slots 31 are used to install multiple protective airbags 2. After contact with the ground, the protective airbags 2 facing the ground cannot be reused due to their inherent elasticity, even if the gas in the protective airbags 2 is expelled. Therefore, after use, the user can replace the protective airbags 2 in other slots 31 with those facing the ground. The protective airbag 2 has an air inlet 211; the pump assembly 4 is mounted on the landing gear 1, and its output end is connected to the air inlet 211. The pump assembly 4 is used to inject gas into the protective airbag 2. When the drone lands at high speed, the pump assembly 4 can inject air into the protective airbag 2, allowing the protective airbag 2 to make contact with the ground first. Through its elasticity, the airbag absorbs the impact force during landing, reducing the impact force directly borne by the rigid landing gear 1. This effectively prevents the rigid landing gear 1 from bending, deforming, or breaking during high-speed landing, thus preventing damage to the drone fuselage. The triggering mechanism of the protective airbag 2 is existing technology and will not be described in detail here.

[0035] Specifically, the tripod 1 is provided with a first fixing ring 11; the first fixing ring 11 is provided with a through groove 111; a locking part 32 is provided between two adjacent locking grooves 31, and the locking part 32 is fixedly connected to the mounting base 3. The locking part 32 is a flexible plate-like structure. A locking surface is provided at the end of the locking part 3 facing away from the mounting base 3. The locking part 32 extends towards the through groove 111; the locking part 32 is engaged and fixed with the through groove 111. In this embodiment, the drone tripod 1 is cylindrical, and the interior of the tripod 1 is a hollow structure. The outer wall surface of the cylindrical tripod 1 is used to contact the ground. The inner diameter of the mounting base 3 is the same as the diameter of the drone tripod 1. During use, the end of the mounting base 3 with the locking part 32 faces the first fixing ring 11, and the mounting base 3 is placed on the stand 1. The locking part 32 is pressed so that it can pass through the through groove 111. After the locking part 32 passes through the through groove 111, the locking surface will contact the side of the first fixing ring 11 that is away from the mounting base 3, thereby fixing the mounting base 3 to the stand 1. In this embodiment, four locking parts 32 are provided. In other embodiments, the stand 1 is a cuboid or a right-angled triangular prism.

[0036] Specifically, on a projection perpendicular to the horizontal plane, the projected area of ​​the first fixing ring 11 is larger than the projected area of ​​the protective airbag 2 before inflation. The first fixing ring 11 is made of rubber. Some people with drone control experience can choose not to deploy the protective airbag 2 when landing the drone, and instead use the first fixing ring 11 to make contact with the ground to land the drone.

[0037] Specifically, the extension direction of the slot 31 is parallel to the horizontal plane. Specifically, the protective airbag 2 includes a mounting plate 22 and an airbag body 21. The airbag body 21 is glued to the mounting plate 22, and an air inlet 211 is provided on the airbag body 21, which is made of polyester fiber. A protrusion is provided on the side of the mounting plate 22 facing away from the airbag body 21, and the protrusion engages and is fixed with the slot 31. During installation, the user can insert the protrusion into the slot 31 along the extension direction of the mounting plate 22 and the airbag body, so that the end of the mounting plate 22 facing the first fixing ring 11 abuts against the first fixing ring 11, thereby installing the protective airbag 2 on the mounting base 3. The operation is simple. In other embodiments, the protective airbag 2 is fixed to the mounting base 3 in a direction perpendicular to the slot 31.

[0038] Specifically, the protective structure also includes: a second fixing ring 5, a connecting rod 6, a third fixing ring 7, and a fixing bolt 8; the second fixing ring 5 is made of rubber. One end of the connecting rod 6 is connected to the second fixing ring 5, and the other end of the connecting rod 6 is connected to the third fixing ring 7; the diameter of the second fixing ring 5 is larger than the diameter of the third fixing ring 7; the mounting base 3 has a protrusion 33 at the end opposite to the locking part 32, and the protrusion 33 is a block structure. The protrusion 33 has external threads; the second fixing ring 5 is sleeved on the mounting base 3, and the second fixing ring 5 abuts against the protective airbag 2, so that the protective airbag 2 is located between the first fixing ring 11 and the second fixing ring 5. Specifically, the second fixing ring 5 has protrusions that are adapted to multiple locking slots 31. When the second fixing ring 5 is sleeved on the mounting base 3, the protrusions are located in the locking slots 31 to prevent the second fixing ring 5 from rotating on the mounting base 3. The third fixing ring 7 is fitted onto the protrusion 33. When the fixing bolt 8 is threadedly connected to the protrusion 33, the fixing bolt 8 abuts against the third fixing ring 7, thereby completely fixing the protective airbag 2 onto the mounting base 3.

[0039] Specifically, the diameter of the second fixing ring 5 is the same as the diameter of the first fixing ring 11. Without deploying the protective airbag 2, the first fixing ring 11 and the second fixing ring 5 simultaneously contact the ground, which increases the stability of the drone during landing.

[0040] Specifically, the protective structure also includes: an air supply pipe 9 and a transition joint 10; the air supply pipe 9 is mounted on the bracket 1, and has a first connection port and a second connection port for connecting to the pump body assembly 4; one end of the transition joint 10 is connected to the first connection port, and the other end of the transition joint 10 is connected to the air inlet 211. Specifically, the end of the transition joint 10 facing away from the air supply pipe 9 is connected to the air inlet 211 of the protective airbag 2 facing the ground, while other air inlets 211 not connected to the transition joint 10 are provided with plugs to prevent dust from entering the air inlet 211. The first fixing ring 11 also has a straight hole, the diameter of which matches the diameter of the air inlet 211. When the end of the mounting plate 22 facing the first fixing ring 11 abuts against the first fixing ring 11, the air outlet will pass through the straight hole, at which time the user can connect the transition joint 10 to the air inlet 211.

[0041] Specifically, the protective airbag 2 has a gripping part 221 at one end facing the second fixing ring 5 for hand gripping, so that the user can remove or replace the used protective airbag 2. Specifically, the gripping part 221 is fixedly mounted on the mounting plate 22. The gripping part 221 has a plate-like structure.
