Description

Technical Field

[0001] The utility model relates to the technical field of UAV mapping, in particular to an anti-shake device for a UAV mapping camera. Background Technique

[0002] In the process of geospatial mapping, the method of aerial photogrammetry is generally adopted, that is, the UAV flies, and at the same time, the camera inside the UAV takes pictures of the ground. Then, the surveying and mapping personnel mark on the topographic map according to the captured pictures to achieve geospatial mapping. In the process of UAV mapping, an anti-shake device is usually required to limit and fix the camera, so that the camera is not interfered by the tilt and shake of the UAV during flight, so as to ensure the accurate mapping of the geospatial.

[0003] Patent CN214930624U proposes an anti-shake device for a UAV mapping camera. When the UAV body flies and generates left-right micro-tilt and shake, the camera body tilts along the inside of the installation frame under the action of the first connecting rod and the support shaft. At this time, under the action of the gravity of the counterweight, the counterweight will drive the second connecting rod and the camera body fixed to it to always remain vertically downward. Then, under the cooperation of the hinged first connecting rod and the second connecting rod, the camera body can be adjusted adaptively in multiple directions, so that the camera body always shoots vertically downward on the plane, and the camera body will not follow the shake or jitter when the UAV body tilts and shakes, so as to achieve the purpose of anti-shake.

[0004] In the above scheme, the camera is rotatably installed relative to the UAV, and the gravity of the counterweight is used to keep the camera vertical when the UAV shakes. The disadvantage of this structure is that the rotatable installation of the camera may be affected by environmental factors and shake, and the camera cannot be locked and installed with the UAV according to the situation, and then unlocked to the rotatable connection state when anti-shake is required. Content of the Utility Model

The structure of the utility model is novel. The camera is installed at the bottom of the UAV through the installation component. Through the connection of the horizontal shaft rod and the vertical rotating shaft seat and the gravity of the counterweight ring, when encountering air flow, the UAV shakes and the camera can be kept facing down. The locking of the horizontal shaft rod can be completed by inserting the second electric push rod, thereby restricting the relative rotation of the camera and the UAV, so as to keep the fixed installation of the camera and the UAV, and the adjustment is more convenient.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: an anti-shake device for a drone mapping camera, comprising a drone body, landing gears are fixed on both sides of the bottom of the drone body, and a mounting assembly is provided in the middle position of the bottom of the drone body, the mounting assembly comprises a top plate, a camera is installed at the bottom of the top plate, a counterweight ring is fixed on the surface of the top plate located on the outer circle of the camera, a vertical rotating shaft seat is installed on the top of the top plate, and a horizontal shaft rod is inserted at the center of the vertical rotating shaft seat, the bottom of the drone body is located on the periphery of the top plate and a protective assembly is provided, the protective assembly comprises a multi-section frame, the multi-section frame is composed of a plurality of groups of slidably connected circular ring frames, and the mounting assembly and the camera are located inside the multi-section frame.

[0007] Furthermore, the mounting assembly also includes a telescopic rod, two telescopic rods are built into the bottom of the drone body, and the extended ends of the telescopic rods are rotatably connected to the two ends of the transverse shaft through a rotating shaft.

[0008] Furthermore, two groups of clamps are symmetrically provided on the inner side of the counterweight ring, and the clamps are clamped on the surface of the camera. A locking bolt is threadedly inserted into the outer side of the counterweight ring, and the other end of the locking bolt is rotatably connected to the clamp via a bearing.

[0009] Furthermore, a wire threading groove is provided at the center of the top plate, and the camera is connected to the system end of the drone body through the wire threading groove.

[0010] Furthermore, a second electric push rod is fixed on both sides of the corresponding wire threading groove inside the top plate, and the extended end of the second electric push rod is connected to a plug rod. Plug holes are opened on the two end surfaces of the transverse shaft, and the plug rod of the second electric push rod can pass through the plug holes and lock with the bottom of the drone body.

[0011] Furthermore, the enclosure assembly also includes a first electric push rod, which is fixed to both sides of the drone body, and a connecting plate is fixed to the extended end of the first electric push rod, and the connecting plate is fixedly connected to both sides of the bottom of the multi-section frame.

[0012] Furthermore, an anti-collision ring is fixed on the outer ring surface of the lowest section of the multi-section casing.

When encountering airflow, the drone can keep the camera facing downward by shaking. The transverse shaft rod can be locked by plugging in the second electric push rod, thereby limiting the relative rotation of the camera and the drone, thereby maintaining a fixed installation of the camera and the drone, and adjusting more conveniently.

Specific embodiments

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: an anti-shake device for a UAV mapping camera, including a UAV body 1, landing gears 11 are fixed on both sides of the bottom of the UAV body 1, and a mounting component 4 is arranged at the middle position of the bottom of the UAV body 1. The mounting component 4 includes a top plate 41, a camera 2 is installed at the bottom of the top plate 41, a counterweight ring 42 is fixed on the surface of the top plate 41 outside the camera 2, a vertical rotating shaft seat 46 is installed at the top of the top plate 41, and a horizontal shaft rod 44 is inserted at the center of the vertical rotating shaft seat 46. An enclosing component 3 is arranged at the periphery of the top plate 41 at the bottom of the UAV body 1. The enclosing component 3 includes a multi-section sleeve frame 33. The multi-section sleeve frame 33 is composed of multiple groups of sliding-connected circular frames, and the mounting component 4 and the camera 2 are located inside the multi-section sleeve frame 33. When using the device, the camera 2 is installed on the mounting component 4. When the UAV is in use, the mounting component 4 is locked to the bottom of the UAV to keep the camera 2 stable. When the UAV shakes due to air flow, the mounting component 4 and the UAV are changed to a rotationally connected state, and the camera 2 is kept vertically downward through the counterweight ring 42, and the enclosing component 3 is used to surround and protect the periphery of the camera 2.

[0027] In this embodiment, the mounting assembly 4 further includes a telescopic rod 45. Two telescopic rods 45 are built into the bottom of the UAV body 1, and the extended ends of the telescopic rods 45 are rotatably connected to both ends of the transverse shaft rod 44 through a rotating shaft. A wire slot 49 is opened at the center of the top plate 41, and the camera 2 is connected to the system end of the UAV body 1 through the wire slot 49. Second electric push rods 47 are fixed on both sides of the top plate 41 corresponding to the wire slot 49, and the extended ends of the second electric push rods 47 are connected with inserting rods. Insertion holes 48 are opened on the surfaces of both ends of the transverse shaft rod 44, and the inserting rods of the second electric push rods 47 can pass through the insertion holes 48 to lock with the bottom of the UAV body 1. When the inserting rods of the second electric push rods 47 are retracted, the transverse shaft rod 44 can rotate with the telescopic rod 45 and the vertical rotating shaft seat 46. At this time, when the UAV sways forward and backward or left and right, the connection with the top plate 41 is maintained by changing the length of the telescopic rod 45 and the angle of the vertical rotating shaft seat 46. At the same time, the top plate 41 keeps vertically downward through the counterweight ring 42. When the inserting rods of the second electric push rods 47 are inserted into the insertion holes 48, the transverse shaft rod 44 cannot rotate at this time. The second electric push rod 47 is locked with the UAV body 1 by means of electromagnetic adsorption, or insertion holes 48 are also opened at the bottom of the UAV body 1. After the inserting rod is inserted into the insertion hole 48 at the bottom of the UAV body 1, it is restricted from rotating and maintains the locked connection between the mounting assembly 4 and the bottom of the UAV body 1.

[0028] In this embodiment, two groups of clamping plates 410 are symmetrically arranged on the inner side of the counterweight ring 42, and the clamping plates 410 clamp the surface of the camera 2. A locking bolt 43 is threadedly inserted on the outer side of the counterweight ring 42, and the other end of the locking bolt 43 is rotatably connected to the clamping plate 410 through a bearing. The camera 2 is fixedly installed through the locking bolt 43, which is convenient for disassembly and assembly.

[0029] In this embodiment, the enclosure assembly 3 further includes a first electric push rod 31. The first electric push rods 31 are fixed on both sides of the UAV body 1, and the extended ends of the first electric push rods 31 are fixed with connecting plates 32. The connecting plates 32 are fixedly connected to both sides of the bottommost part of the multi-section sleeve frame 33. An anti-collision ring 34 is fixed on the outer surface of the bottommost section of the multi-section sleeve frame 33. A space for the camera 2 and the mounting assembly 4 to rotate is provided inside the multi-section sleeve frame 33. In windy weather, the first electric push rod 31 drives the multi-section sleeve frame 33 to unfold through the connecting plate 32 to wrap the camera 2 and the mounting assembly 4 inside, preventing the external airflow from destroying the balance of the mounting assembly 4. The space inside the multi-section sleeve frame 33 can meet the requirement that when the UAV sways, the camera 2 generates an angular deviation from the UAV through the action of the counterweight ring 42. At the same time, the enclosure assembly 3 can also be used when the UAV lands. The anti-collision ring 34 at the bottom can prevent the camera 2 from colliding with the ground.

[0030] When using the device, the camera 2 is installed on the installation component 4. When the insertion rod of the second electric push rod 47 retracts, the transverse shaft rod 44 can rotate with the telescopic rod 45 and the vertical rotating shaft seat 46. At this time, when the drone sways forward and backward or left and right, the connection with the top plate 41 is maintained by changing the length of the telescopic rod 45 and the angle of the vertical rotating shaft seat 46. At the same time, the top plate 41 maintains a vertical downward direction through the counterweight ring 42. When the insertion rod of the second electric push rod 47 inserts into the jack 48, the transverse shaft rod 44 cannot rotate at this time. The second electric push rod 47 is locked to the drone body 1 by means of electromagnetic adsorption. Alternatively, a jack 48 is also provided at the bottom of the drone body 1. After the insertion rod inserts into the jack 48 at the bottom of the drone body 1, it is restricted from rotating, maintaining the locked connection between the installation component 4 and the bottom of the drone body 1. When encountering weather with strong airflow, the first electric push rod 31 drives the multi-section sleeve frame 33 to expand through the connecting plate 32 to wrap the camera 2 and the installation component 4 inside, preventing the external airflow from destroying the balance of the installation component 4. The space inside the multi-section sleeve frame 33 can meet the requirement that when the drone sways, the camera 2 generates an angular deviation from the drone through the action of the counterweight ring 42. At the same time, the enclosure component 3 can also be used when the drone lands. The camera 2 can be prevented from colliding with the ground through the anti-collision ring 34 at the bottommost part.

For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic features of the present utility model, the present utility model can be implemented in other specific forms.

This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
