Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, specifically relating to a gimbal structure for unmanned aerial vehicles (UAVs). Background Technology

[0002] The gimbal structure of a drone mainly consists of the gimbal body, stabilization system, drive motor, sensors, and control unit. The gimbal body is usually made of lightweight materials such as aluminum alloy or carbon fiber to ensure light weight and high strength. The stabilization system uses sensors such as gyroscopes and accelerometers to detect the drone's attitude in real time and adjusts the motors to drive the gimbal to keep the camera level and stable.

[0003] Chinese patent publication number CN115447781A discloses an airborne gimbal structure for a drone, including a mounting plate and a nozzle. The nozzle is fixed to a platform plate, and the platform plate is connected to the mounting plate via an attitude adjustment mechanism. The attitude adjustment mechanism is used to adjust the orientation of the nozzle relative to the mounting plate. The structure also includes a hanger fixedly connected to the mounting plate. The hanger has a tube located behind the nozzle. One end of the tube is a first inlet for connecting a fire hose, and the other end is a second inlet for connecting a connecting pipe. The water inlet of the nozzle is a third inlet for connecting the connecting pipe. This structure can reduce the impact of adjusting the water spray direction on the drone's position and attitude stability.

[0004] However, the current gimbal structure has the following problems: the existing gimbal structure installation method is very limited and cannot meet the portable installation and disassembly of airborne gimbals, and the installation structure is not stable enough. Therefore, we propose an unmanned aerial vehicle (UAV) gimbal structure. Utility Model Content

[0005] The purpose of this utility model is to provide a UAV-borne gimbal structure that can solve the problems of the limited installation methods of existing gimbal structures in related technologies, which cannot meet the requirements of portable installation and disassembly of airborne gimbals, and the insufficient stability of the installation structure.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A drone gimbal structure includes a drone body, four supports fixedly connected to the sides of the drone body, and flight devices fixedly connected to the sides of each support. A fixing device is provided at the bottom of the drone body, the fixing device including two vertical plates, the tops of the two vertical plates being fixedly connected to the bottom of the drone body, and two fixing plates fixedly connected between the two vertical plates. A drive assembly is provided at the bottom of the drone body, the drive end of the drive assembly being hinged to a hinge rod, and the end of the hinge rod away from the drone body being hinged to the same cone block.

[0008] The drive assembly includes a bidirectional threaded rod, the top of which is rotatably connected to the bottom of the drone body, and a rotating rod fixedly connected to the bottom of the bidirectional threaded rod. Two threaded sleeves are threadedly connected to opposite circumferential surfaces of the bidirectional threaded rod. A limiting rod is fixedly connected to the bottom of the drone body, and the two threaded sleeves pass through and slide on the circumferential surface of the limiting rod. The two threaded sleeves are the drive ends of the drive assembly.

[0009] The fixing plate is located on the movement trajectory of the cone block, and the end of the cone block near the fixing plate is provided with a spike.

[0010] An auxiliary device is provided on the circumferential surface of the rotating rod. The auxiliary device includes a friction wheel, the inner wall of which is fixedly connected to the circumferential surface of the rotating rod. An auxiliary frame is slidably connected to the bottom of the vertical plate. The same C-shaped rod is fixedly connected to the sides of the two vertical plates. A gimbal protrusion is rotatably connected to the circumferential surface of the C-shaped rod.

[0011] The auxiliary frame has a rough surface on the side near the friction wheel, and the circumferential surface of the friction wheel has a rough surface.

[0012] The rough surface of the friction wheel is in contact with the rough surface of the auxiliary frame, and the auxiliary frame is in contact with the main body of the UAV.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention, through the setting of a fixing device, enables the vertical plate, fixing plate, bidirectional threaded rod, threaded sleeve, hinge rod, cone block, limit rod, and rotating rod to cooperate. Before the UAV body flies, the operator twists the rotating rod, which drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod causes the threaded sleeve to move in opposite directions under the restriction of the limit rod. The opposite movement of the threaded sleeve causes the cone block to penetrate into the fixing plate under the force of the hinge rod, thereby enhancing stability. This avoids the limitations of existing gimbal structure installation methods, which cannot meet the portable installation and disassembly requirements of airborne gimbals and have insufficient structural stability.

[0015] This invention, through the setting of an auxiliary device, enables the friction wheel, auxiliary frame, C-shaped rod, and gimbal protrusion to cooperate. At the same time, the rotation of the rotating rod drives the rotation of the friction wheel. The friction generated by the rotation of the friction wheel and the contact of the rough surface of the auxiliary frame causes the auxiliary frame to move. The movement of the auxiliary frame enhances the alignment of the airborne gimbal with the UAV body during flight, ensuring the stable operation of the UAV body and the airborne gimbal.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-5 As shown, a UAV gimbal structure includes a UAV body 1. Four supports 2 are fixedly connected to the sides of the UAV body 1, and flight devices 3 are fixedly connected to the sides of each support 2. A fixing device 4 is provided at the bottom of the UAV body 1. The fixing device 4 includes two vertical plates 41, the tops of which are fixedly connected to the bottom of the UAV body 1. Two fixing plates 42 are fixedly connected between the two vertical plates 41. A drive assembly is provided at the bottom of the UAV body 1. A hinge rod 45 is hinged to the drive end of the drive assembly. A cone block 46 is hinged to the end of the hinge rod 45 away from the UAV body 1. The drive assembly includes... The device includes a bidirectional threaded rod 43, the top of which is rotatably connected to the bottom of the drone body 1. A rotating rod 48 is fixedly connected to the bottom of the bidirectional threaded rod 43. Two threaded sleeves 44 are threadedly connected to the opposite circumferential surface of the bidirectional threaded rod 43. A limiting rod 47 is fixedly connected to the bottom of the drone body 1. The two threaded sleeves 44 pass through and slide on the circumferential surface of the limiting rod 47. The two threaded sleeves 44 are the driving ends of the drive assembly. The fixed plate 42 is located on the movement trajectory of the cone block 46. The end of the cone block 46 near the fixed plate 42 is provided with a spike. The spike design can be easily inserted into the fixed plate 42 to enhance stability.

[0025] According to the above structure, before the main body 1 of the UAV flies, the staff twists the rotating rod 48. The rotation of the rotating rod 48 drives the rotation of the bidirectional threaded rod 43. The rotation of the bidirectional threaded rod 43 drives the threaded sleeve 44 to move towards each other under the restriction of the limiting rod 47. The movement of the threaded sleeve 44 towards each other causes the cone block 46 to penetrate into the fixed plate 42 under the force of the hinge rod 45, thereby enhancing stability and avoiding the limitations of the existing gimbal structure installation method, which cannot meet the portable installation and disassembly of the airborne gimbal, and the insufficient stability of the installation structure.

[0026] like Figures 1-5 As shown, an auxiliary device 5 is provided on the circumferential surface of the rotating rod 48. The auxiliary device 5 includes a friction wheel 51. The inner wall of the friction wheel 51 is fixedly connected to the circumferential surface of the rotating rod 48. An auxiliary frame 52 is slidably connected to the bottom of the vertical plate 41. The same C-shaped rod 53 is fixedly connected to the sides of the two vertical plates 41. A gimbal protrusion 54 is rotatably connected to the circumferential surface of the C-shaped rod 53. The side of the auxiliary frame 52 near the friction wheel 51 is rough. The circumferential surface of the friction wheel 51 is rough. The rough surface of the friction wheel 51 contacts the rough surface of the auxiliary frame 52. When the two friction surfaces are in contact, the auxiliary frame 52 can be moved. The auxiliary frame 52 contacts the main body 1 of the UAV.

[0027] According to the above structure, the rotation of the rotating rod 48 drives the rotation of the friction wheel 51. The friction generated by the rotation of the friction wheel 51 and the contact of the rough surface of the auxiliary frame 52 causes the auxiliary frame 52 to move. The movement of the auxiliary frame 52 enhances the alignment of the airborne gimbal with the UAV body 1 during flight, ensuring the stable operation of the UAV body 1 and the airborne gimbal.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
