Description

Technical Field

[0001] The utility model relates to the technical field of police drones, in particular to a police drone with an anti-fall protection mechanism. Background Art

[0002] A police drone is a type of drone system designed and used specifically for law enforcement agencies. It combines drone technology with police operational needs and is equipped with various professional police equipment to perform police duties.

[0003] A public announcement (publication) number: CN216509129U discloses a police drone with an anti-fall protection mechanism. This technology discloses "including a drone body, an air duct installed inside the drone body, the air duct extending to the outside of the drone body, an airbag installed inside the drone body, the airbag and the air duct communicating with each other, a sealing cover hingedly connected to the upper surface of the drone body, the sealing cover located directly above the airbag, an opening and closing mechanism provided inside the drone body, the opening and closing mechanism provided on one side of the air duct, and an internal sliding sleeve of the air duct provided with a sealing ball fixedly connected to one end of the opening and closing mechanism, etc. The invention has the technical effects of automatically turning on the alarm and warning light when the drone body is low on power, and simultaneously inflating the airbag to slow down the drone body's descent, thereby allowing the drone body to land smoothly."

[0004] However, although the aforementioned comparative documents can control the sealing ball and the airbag through the opening and closing mechanism when the drone body is low on power, the flight of the drone is uncertain. The drone may encounter unexpected situations during flight, which may cause it to fall suddenly. In this case, the drone may flip when it falls, and air may not be able to pass through the holes of the drone and control the airbag, which may cause the drone to crash.

[0005] To solve the above problems, this application proposes a police drone with an anti-fall protection mechanism. Utility Model Content

[0006] The utility model aims to solve the technical problems existing in the prior art and provides a police drone with an anti-fall protection mechanism.

[0007] The technical solution of the utility model to solve the above technical problems is as follows: a police drone with an anti-fall protection mechanism, comprising a drone housing, wherein a protective structure is provided inside the drone housing;

[0008] The protective structure includes an electric telescopic rod fixedly connected to the inside of the drone shell, a rotating rod rotatably connected to the inside of the drone shell, one end of the rotating rod is located outside the drone shell, and the end of the rotating rod located outside the drone shell is fixedly connected to a handle. The telescopic tube of the electric telescopic rod and the end of the rotating rod away from the handle are clamped with each other, the outer wall of the rotating rod is fixedly connected to a steel wire rope, one end of the steel wire rope is movably connected to a pull ring, and the bottom of the pull ring is fixedly connected to a weight block, an airbag is provided inside the drone shell, a protective plate is rotatably connected to the drone shell, a sensor is provided inside the drone shell, and a buffer structure is provided at the bottom of the drone shell.

[0009] The buffer structure includes a support rod fixedly connected to the bottom of the drone shell, a round block fixedly connected to the bottom of the support rod, an extension rod fixedly connected to the outer wall of the support rod, a fixed tube sleeved on the outer side of the extension rod, a spring fixedly connected to the inner wall of the fixed tube, one end of the spring fixedly connected to one end of the extension rod. By setting up the buffer structure, the drone is buffered to avoid a large impact when the drone falls and damage.

[0010] A sealing gasket is fixedly connected to the weight block, and one side of the sealing gasket is in contact with the outer wall of the drone shell. By providing the sealing gasket, the contact between the weight block and the drone shell is sealed, thereby preventing the airbag from expanding when the drone is flying stably.

[0011] The rotating rod is fixedly connected with a baffle, and the baffle is provided to limit the position of the handle to avoid affecting the downward movement of the weight block.

[0012] A first magnetic block is provided on the drone shell, and a second magnetic block is provided on the protective plate. One side of the second magnetic block is in contact with one side of the first magnetic block. By providing the first magnetic block and the second magnetic block, the initial positioning of the protective plate is achieved to avoid affecting the release of the airbag.

[0013] The drone shell is provided with a protective ring, which is sleeved on the outside of the wings of the drone shell. By providing the protective ring, the wings of the drone are protected to prevent the wings of the drone from being damaged when the drone falls.

[0014] The beneficial effects of the utility model are:

[0015] When a drone encounters an emergency during flight and falls, the sensor will detect the drone's situation and transmit a signal to the electric telescopic rod, causing the electric telescopic rod to move, thereby causing the weight block to fall under the action of gravity. At this time, the falling of the weight block will cause the through holes opened on the drone's shell to leak out, causing the protective structure of the drone shell to expand due to air, thereby protecting the drone. At the same time, when the weight block falls, the weight of the weight block will cause the drone to maintain a relatively stable state when falling, thereby preventing the drone from tilting, thereby avoiding affecting the use of the airbag.

[0016] By setting up a buffer structure, the drone can be cushioned. When the drone falls to the ground, the round block first contacts the ground. At this time, the round block is deformed outward under the force of gravity. At this time, the extension rod will limit the deformation of the support rod under the action of the spring, thereby preventing the drone from being hit hard when it falls and causing damage.

[0030] Reference Figure 1-3 , a police drone with an anti-fall protection mechanism, comprising a drone housing 1, wherein a protection structure 2 is provided inside the drone housing 1;

[0031] The protective structure 2 includes an electric telescopic rod 203 fixedly connected to the inside of the drone shell 1, and a rotating rod 204 is rotatably connected to the inside of the drone shell 1. The electric telescopic rod 203 is used to fix the rotating rod 204 to prevent the rotating rod 204 from rotating unnecessarily. One end of the rotating rod 204 is located outside the drone shell 1, and the end of the rotating rod 204 located outside the drone shell 1 is fixedly connected to a handle 205. The handle 205 can facilitate the user to control the rotating rod 204. The telescopic tube of the electric telescopic rod 203 is mutually clamped with the end of the rotating rod 204 away from the handle 205. The outer wall of the rotating rod 204 is fixedly connected to a steel wire rope 206. One end of the steel wire rope 206 The end is movably connected with a pull ring 207, and the bottom of the pull ring 207 is fixedly connected with a weight block 208. The coordinated use of the wire rope 206, the pull ring 207 and the weight block 208 can realize the falling of the weight block 208. The falling of the weight block 208 will increase the stability of the drone, thereby avoiding the tilting of the drone when falling. An airbag 201 is provided inside the drone shell 1, and the airbag 201 is used to slow down the falling speed of the drone. A protective plate 202 is rotatably connected to the drone shell 1, and a sensor 4 is provided inside the drone shell 1. The sensor 4 is set as an acceleration sensor 4, and a buffer structure 3 is provided at the bottom of the drone shell 1.

[0032] Reference Figure 1 and Figure 4 The buffer structure 3 includes a support rod 301 fixedly connected to the bottom of the drone shell 1. The support rod 301 is set to a soft material that can be shaped. A round block 302 is fixedly connected to the bottom of the support rod 301. The support rod 301 is used to prevent the support rod 301 from deflecting when the drone shell 1 falls. An extension rod 303 is fixedly connected to the outer wall of the support rod 301. A fixed tube 304 is sleeved on the outer side of the extension rod 303. A spring 305 is fixedly connected to the inner wall of the fixed tube 304. One end of the spring 305 is fixedly connected to one end of the extension rod 303. By cooperating with the extension rod 303 and the spring 305, the deformation of the support rod 301 can be limited, thereby preventing the drone from being damaged due to a large impact when it falls.

[0033] Reference Figure 3 A sealing gasket 209 is fixedly connected to the weight block 208, and one side of the sealing gasket 209 is in contact with the outer wall of the drone shell 1. The sealing gasket 209 is used to achieve a seal between the weight block 208 and the drone shell 1 to prevent gas from flowing into the interior of the drone shell 1 through the connection between the weight block 208 and the drone shell 1 when the drone is flying, thereby preventing the airbag 201 from expanding when the drone is flying stably.

[0034] Reference Figure 3A baffle 5 is fixedly connected to the rotating rod 204, and the baffle 5 is used to limit the handle 205 to prevent the handle 205 from leaving the range of the rotating rod 204 when the rotating rod 204 is retracting the handle 205, thereby avoiding affecting the downward movement of the weight block 208.

[0035] Reference Figure 5 A first magnetic block 6 is provided on the drone housing 1, and a second magnetic block 7 is provided on the protective plate 202. One side of the second magnetic block 7 is in contact with one side of the first magnetic block 6. The first magnetic block 6 and the second magnetic block 7 are used in conjunction to achieve the initial positioning of the protective plate 202, thereby preventing the protective plate 202 from flipping over when not in use, thereby avoiding affecting the release of the airbag 201.

[0036] Reference Figure 1 A protective ring 8 is provided on the drone shell 1, and the protective ring 8 is sleeved on the outside of the wing of the drone shell 1. The protective ring 8 is used to protect the wings of the drone to prevent the wings of the drone from being damaged when the drone falls.

[0037] Working principle:

[0038] The police drone with an anti-fall protection mechanism, when the drone encounters an emergency during flight and falls, the sensor 4 will detect the drone's situation and transmit a signal to the electric telescopic rod 203. After receiving the signal, the electric telescopic rod 203 will separate the telescopic end from the rotating rod 204. At this time, the rotating rod 204 will rotate under the action of the weight block 208. At the same time, the weight block 208 will fall. The falling of the weight block 208 will cause the through hole opened on the drone shell 1 to leak out, so that the air bag 201 will be expanded by air, thereby achieving the purpose of protecting the drone. The falling speed of the drone is slowed down. At the same time, after the weight block 208 falls, the weight of the weight block 208 will make the drone maintain a relatively stable state when falling, thereby preventing the drone from tilting, thereby avoiding affecting the use of the airbag 201. When the drone falls to the ground, the round block 302 first contacts the ground. At this time, the round block 302 is deformed outward by gravity. At this time, the extension rod 303 will limit the deformation of the support rod 301 under the action of the spring 305, thereby preventing the drone from being hit hard when falling and being damaged.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0040] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention.
