[0063] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0064] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0065] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0066] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0067] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0068] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0069] The embodiment of the present application provides a drone that can land smoothly when it crashes out of control. Figure 1 and Figure 2 As shown, the UAV includes a main body 1 , a parachute assembly 2 and a tripod assembly 3 , and the tripod assembly 3 is arranged on the main body 1 .

[0070] In this embodiment, if Figure 1 As shown, when the drone is flying or landing normally, the parachute 21 is stored in the box 22 on the main body 1. Figure 2 As shown, a control circuit and an acceleration sensor are provided in the tripod assembly 3 of the drone or in the main body 1 of the drone. When the drone loses control and falls, the acceleration sensor sends a signal to the control circuit, and the control circuit controls the parachute assembly 2 to be in an open state, thereby reducing the descent speed of the out-of-control drone, preventing the falling drone from being damaged, and reducing the loss of the drone owner.

[0071] The present application embodiment provides a tripod assembly, such as Figures 1 to 4As shown, the tripod assembly 3 is used to be set on the main body 1 of the drone, and the tripod assembly 3 includes a tripod shell 31 and an airbag assembly 32, wherein the tripod shell 31 has a first inner cavity 35, and the airbag assembly 32 is accommodated in the first inner cavity 35 in a non-opened state.

[0072] In this embodiment, if Figures 1 to 4 As shown, when the drone is flying or landing normally, the airbag 322 is stored in the tripod. When the drone loses control and falls, the airbag assembly 32 is in an open state. The airbag assembly 32 can reduce the impact of the drone and the ground when it lands, prevent the falling drone from causing damage to people and objects on the ground, and keep the internal structure of the drone intact, reducing the loss of the drone owner.

[0073] Furthermore, the tripod housing 31 defines a first inner cavity 35, within which the airbag assembly 32 is housed, reducing the size of the drone. Furthermore, the airbag assembly 32 does not occupy the space below the main body 1, allowing food or cargo to be attached below the main body 1 without affecting the drone's food and delivery capabilities. The tripod housing 31 also includes a second mounting hole 311, through which the main body 1 of the drone can be connected to the tripod housing 31, specifically by riveting.

[0074] Specifically, all tripods of the drone can be set to the tripod assembly 3 provided in this application, or only some of the tripods can be set to the tripod assembly 3 provided in this application, and the other tripods can be ordinary tripods without airbag assemblies 32.

[0075] In a specific embodiment, Figures 4-6 As shown, the airbag assembly 32 includes a gas generator 321 and an airbag 322 . The first end 322 a of the airbag 322 is connected to the gas generator 321 . When the airbag 322 is in the open state, the second end 322 b of the airbag 322 is out of the first inner cavity 35 .

[0076] In this embodiment, if Figures 4-6 As shown, a gas generator 321 and an airbag 322 are located within the first inner cavity 35. The gas generator 321 is connected to a control circuit, and the first end 322a of the airbag 322 is in communication with the gas generator 321. If the drone loses control and crashes, the control circuit controls the gas generator 321 to generate a large amount of gas. This large amount of gas enters the airbag 322, causing the second end 322b of the airbag 322 to escape from the first inner cavity 35 and inflate the airbag 322. The drone has multiple legs, and the inflated airbags 322 contact the ground, thereby reducing the impact of the ground on the drone and ensuring a smooth landing.

[0077] In a specific embodiment, Figure 4 and Figure 6As shown, the airbag assembly 32 further includes a first shell 323 , and the gas generator 321 is located inside the first shell 323 . The first shell 323 is limited by the inner wall of the tripod shell 31 .

[0078] In this embodiment, if Figure 4 As shown, the first housing 323 protects the gas generator 321, preventing gas from entering the airbag 322 and damaging the gas generator 321 and the tripod housing 31 during inflation, thereby affecting the normal deployment of the airbag 322. The first housing 323 cooperates with the inner wall of the tripod housing 31 to position the gas generator 321 relative to the tripod housing 31, ensuring the structural stability of the airbag assembly 32 and improving its reliability.

[0079] In addition, the airbag assembly 32 may not include the first shell 323 , and the airbag assembly 32 may be directly placed in the first inner cavity 35 .

[0080] In a specific embodiment, Figure 4 and Figure 6 As shown, the airbag assembly 32 further includes a second shell 324 , which covers the first end 322 a of the airbag 322 , and the second shell 324 cooperates with the inner wall of the tripod shell 31 to limit position.

[0081] In this embodiment, if Figure 4 As shown, the second housing 324 covers the first end 322a of the airbag 322. Because the second housing 324 is relatively rigid relative to the airbag 322, the airbag 322 is less likely to expand toward the end where the gas generator 321 is located. This ensures that deployment of the airbag 322 does not damage the gas generator 321 or the drone's main body 1. The second housing 324 cooperates with the inner wall of the tripod housing 31 to secure the airbag 322 relative to the tripod housing 31, ensuring the structural stability of the airbag assembly 32 and improving its reliability.

[0082] In a specific embodiment, Figure 3 and Figure 4 As shown, the tripod shell 31 includes a first section 314 and a second section 315. The diameter of the second section 315 gradually decreases from close to the first section 314 to away from the first section 314. The first shell 323 and the second shell 324 are both limited by the inner wall of the second section 315.

[0083] In this embodiment, if Figure 3 and Figure 4As shown, the first section 314 of the tripod housing 31 is connected to the drone's main body 1, and the second section 315 is used to accommodate the airbag assembly 32. The diameter of the second section 315 gradually decreases from near the first section 314 to away from the first section 314. This allows the first and second housings 323, 324 to cooperate with the inner wall of the second section 315 to limit their position. The first and second housings 323, 324 cannot move downward relative to the second section 315, keeping the gas generator 321 in the first housing 323 and the airbag 322 connected to the second housing 324 fixed relative to the second section 315, thereby ensuring the structural stability of the airbag assembly 32 and improving its reliability.

[0084] In a specific embodiment, Figure 4 and Figure 6 As shown, the diameter of at least a portion of the first shell 323 gradually increases from the airbag 322 toward the gas generator 321 , so that the first shell 323 and the second section 315 cooperate to limit the position.

[0085] In this embodiment, if Figure 4 As shown, the position where the first housing 323 has the largest diameter cooperates with the second section 315 to limit its position, preventing the first housing 323 and gas generator 321 from moving relative to the second section 315 toward the airbag 322. This prevents the connection between the gas generator 321 and the control circuit from being severed due to insufficient length, thereby ensuring that the gas generator 321 can function properly in the event of a drone crash and improving the reliability of the airbag assembly 32. The position where the first housing 323 has the smallest diameter cooperates with the gas generator 321 to limit its position, thereby limiting its movement relative to the second section 315 in a direction perpendicular to the height of the tripod housing 31, keeping the gas generator 321 in a fixed position and improving its reliability.

[0086] In a specific embodiment, Figure 4 and Figure 6 As shown, the diameter of the second shell 324 gradually increases from the gas generator 321 to the airbag 322, so that the second shell 324 and the second section 315 are matched and limited.

[0087] In this embodiment, if Figure 4As shown, the location of the second housing 324 with the largest diameter cooperates with the second section 315 to limit its position, preventing the second housing 324 from moving relative to the second section 315 toward the airbag 322. This prevents the airbag 322 from being compressed and stacked, which could affect its deployment in the event of a loss of control and a crash of the drone, thereby improving the reliability of the airbag assembly 32. The location of the second housing 324 with the smallest diameter is connected to the first housing 323 and cooperates with the first end 322a of the airbag 322 to ensure a secure connection between the gas generator 321 and the airbag 322, ensuring that the gas generated by the gas generator 321 can smoothly enter the airbag 322, and thus improving the reliability of the airbag assembly 32.

[0088] In a specific embodiment, Figure 4 and Figure 6 As shown, the tripod assembly 3 also includes a damper assembly 33 near the second end 322b and a foot 34 connected to the damper assembly 33. When the airbag assembly 32 is in the non-open state, at least a portion of the damper assembly 33 is accommodated in the first inner cavity 35, and the damper assembly 33 is fixed to the tripod shell 31. When the airbag assembly 32 is in the open state, the damper assembly 33 and the foot 34 can be detached from the tripod shell 31.

[0089] In this embodiment, the damper assembly 33 and the foot 34 are used for landing of the drone during normal operation, so as to reduce the impact of the ground on the drone body 1 and ensure that the drone is not damaged during landing. Figure 4 As shown, at least a portion of the damper assembly 33 is housed within the first inner cavity 35, which reduces the size of the drone and makes it more lightweight during flight. The damper assembly 33 and the foot 34 can be detached from the tripod housing 31, ensuring the normal deployment of the airbag 322, allowing the airbag 322 to reduce the impact of the ground on the drone during landing.

[0090] In a specific embodiment, Figure 4 and Figure 6 As shown, the damper assembly 33 includes a damping cylinder 331, a movable member 332, an elastic member 333, and a connecting member 334. The damping cylinder 331 has a second inner chamber 331a for containing damping fluid and a first movable chamber 331b communicating with the second inner chamber 331a. The movable member 332 is movable within the second inner chamber 331a along the height direction of the tripod assembly 3. The elastic member 333 is sleeved on the movable member 332. The connecting member 334 is sleeved on the damping cylinder 331 and connected to the tripod housing 31. The foot 34 is provided with a second movable chamber 341. One end of the movable member 332 extends through the second inner chamber 331a into the first movable chamber 331b, and the second end of the movable member 332 extends into the second movable chamber 341.

[0091] In this embodiment, if Figure 4As shown, the movable member 332 is capable of moving up and down within the second inner cavity 331a, the first movable cavity 331b, and the second movable cavity 341 along the height of the tripod housing 31. When the drone lands normally, the foot 34 contacts the ground. Since one end of the movable member 332 extends into the second movable cavity 341, the foot 34 pushes the movable member 332 upward along the height of the tripod housing 31. This reduces the space between the movable member 332 and the first movable cavity 331b, compressing the elastic member 333 attached to the movable member, converting the ground's impact on the foot 34 into elastic force within the elastic member 333. The damping fluid in the second inner cavity 331a flows through the second inner cavity 331a, converting the energy of the ground's impact on the foot 34 into heat through friction and dissipating it, thereby preventing the ground's impact from directly impacting the drone's main body 1 and damaging its internal structure. Furthermore, the movable member 332 can be reset by the restoring force of the elastic member 333, eliminating the need for manual operation or external drive components, thus improving the user experience. Therefore, the damper assembly 33 and the foot 34 ensure a safe landing of the drone.

[0092] In addition, a slide rail is provided on the damping cylinder 331 , and the connecting member 334 is slidably sleeved on the damping cylinder 331 , and the annular protrusion at the bottom of the damping cylinder 331 can limit the connecting member 334 to prevent the connecting member 334 from sliding off the damping cylinder 331 .

[0093] In a specific embodiment, Figure 4 and Figure 7 As shown, the movable member 332 is provided with a leakage hole 332b for the damping fluid to pass through.

[0094] In this embodiment, if Figure 7 As shown, the end surface and circumferential side wall of the movable part 332 are provided with leakage holes 332b, so as to realize the alternating flow of the damping fluid in the second inner cavity 331a on both sides of the movable part 332, thereby preventing the excessive pressure of the damping fluid from affecting the movement of the movable part 332 during the movement of the movable part 332. Figure 7 As shown, the movable part 332 is further provided with a weight-reducing hole 332 a , which can reduce the weight of the movable part 332 , thereby reducing the weight of the drone itself, allowing the drone to carry more food or cargo.

[0095] In addition, if Figure 4 and Figure 6 As shown, the damper assembly 33 also includes an end cover 336 and a seal 337. The end cover 336 is installed at the bottom of the damping cylinder 331 and a through hole is provided on the end cover 336. One end of the movable part 332 extends out of the damping cylinder 331 through the through hole and is connected to the foot 34. The seal 337 seals the connection between the movable part 332 and the end cover to prevent the damping fluid in the second inner cavity 331a from leaking from the through hole.

[0096] In a specific embodiment, Figure 3 、 Figure 4 and Figure 8 As shown, the damper assembly 33 is further provided with a dust cover 335 . The dust cover 335 is corrugated and is provided on the outside of the tripod housing 31 .

[0097] In this embodiment, if Figure 4 As shown, the foot 34 is provided with an annular groove 342, and the dust cover 335 is connected to the foot 34 through the annular groove 342. The dust cover 335 also prevents the foot 34 from falling off the tripod housing 31 after the drone takes off. The dust cover 335 can prevent external dust and water from coming into contact with the movable part 332, thereby preventing dust and water from damaging the seal between the end cover and the movable part 332 and affecting the operation of the damper assembly 33, thereby improving the reliability of the damper assembly 33 and extending the life of the damper assembly 33.

[0098] In addition, the side wall of the dust cover 335 is in a corrugated structure, which is easy to deform and has little effect on the movement of the movable part 332 and the foot 34 along the height direction of the tripod shell 31.

[0099] In a specific embodiment, Figure 8 As shown, the dust cover 335 is provided with a vent hole 335a.

[0100] In this embodiment, if Figure 8 As shown, the bottom of the dust cover 335 is provided with a first mounting hole 335b, and the first mounting hole 335b is engaged with the annular groove 342 of the foot 34 to achieve the connection between the foot 34 and the dust cover 335. Figure 4 and Figure 8 As shown, vent holes 335a are provided on the sidewall of the dust cover 335. When the foot 34 contacts the ground and moves upward along the height direction of the tripod housing 31, the distance between the damper and the tripod housing 31 decreases, compressing the dust cover 335. When the drone takes off, the foot 34 moves downward along the height direction of the tripod housing 31 under the action of gravity, increasing the distance between the damper and the tripod housing 31 and stretching the dust cover 335. During the compression or stretching process of the dust cover 335, the air pressure inside the dust cover 335 increases or decreases. The vent holes 335a enable the interior of the dust cover 335 to communicate with the outside world, thereby balancing the air pressure inside the dust cover 335 and preventing the air pressure inside the dust cover 335 from being too high or too low, which may affect the operation of the damper assembly 33.

[0101] In addition, the damper assembly 33 is not limited to the above forms, and other forms of dampers can also be applied to the drone provided in this application.

[0102] In a specific embodiment, Figure 4As shown, the tripod housing 31 is provided with a clamping portion 312 , and the tripod housing 31 is connected to the connecting member 334 via the clamping portion 312 .

[0103] In this embodiment, if Figure 4 As shown, the connecting member 334 is provided with an annular protrusion 334a, which can be engaged with the engaging portion 312 of the tripod shell 31, thereby fixing the damper assembly 33 in the first inner cavity 35 of the tripod shell 31 and reducing the volume of the tripod assembly 3.

[0104] In a specific embodiment, Figure 4 and Figure 6 As shown, the tripod shell 31 is provided with a notch 313 near the clamping portion 312. The notch 313 can be broken when the airbag assembly 32 is converted from a non-opening state to an opening state, so that the damper assembly 33, the ground foot 34 and the clamping portion 312 are separated from the tripod shell 31.

[0105] In this embodiment, when the drone loses control and crashes, the airbag assembly 32 is converted from a non-opening state to an opening state, and the airbag 322 expands rapidly. The impact force generated by the expansion of the airbag 322 directly acts on the damper assembly 33 below the airbag 322. Since the damper assembly 33 is clamped to the tripod shell 31 and the notch 313 of the tripod shell 31 is the thinnest and most susceptible to breakage, the impact force generated by the expansion of the airbag 322 will act on the clamping portion 312 of the tripod shell 31 and cause the tripod shell 31 to break at the notch 313, thereby causing the damper assembly 33, the ground foot 34 and the clamping portion 312 to fall off from the tripod shell 31, and the second end 322b of the airbag 322 to fall out of the first inner cavity 35. The airbag assembly 32 is converted to the opening state, thereby reducing the impact of the ground and protecting the main body 1 of the drone from damage.

[0106] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
