Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) surveying and mapping, and in particular to a camera surveying and mapping fixing device for an UAV based on surveying and mapping services. Background Art

[0002] Surveying and mapping refers to measuring and drawing. When conducting surveying and mapping, it is sometimes necessary to observe the geographical environment. In order to facilitate the observation of the geographical environment, people generally use drones equipped with cameras. The drones are flown to place the cameras at high altitudes to photograph the geographical environment.

[0003] For example, Chinese patent CN219668508U discloses a camera surveying and fixing device for drones based on surveying and mapping services, which includes a fixing ring, a threaded rod, a nut, a connecting block, a fixing rod and a placement frame, etc.; the left and right sides of the placement frame are symmetrically connected to the fixing rods in a front-to-back manner.

[0004] However, in the existing technology, in traditional drone mapping, the camera fixing method is often relatively simple, which to a certain extent increases the risk of the camera loosening during flight. The single fixing method usually means that the camera is only connected to the drone platform through a few fixing points or slots. Such a design is sufficient in simple application scenarios, but under the influence of complex and changeable flight environments and external factors such as wind resistance, airflow fluctuations, temperature changes, etc., the fixing structure will become loose or deformed, thereby affecting the stability of the camera and the shooting quality. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that the fixed structure may become loose or deformed under the influence of complex and changeable flight environments and external factors, and to propose a camera surveying and fixing device for drones based on surveying and mapping services.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a camera surveying and mapping fixing device for a drone based on surveying and mapping services, comprising a mounting plate, fixing brackets fixedly connected to both sides of the bottom of the mounting plate, a positioning mechanism installed at the bottom of the fixing bracket, and a clamping mechanism installed between the two fixing brackets;

[0007] The positioning mechanism includes a fixed splint and a movable splint, the top of the fixed splint is fixedly connected to the bottom of the fixed frame, one side of the fixed splint is rotatably connected to a threaded rod, the top and bottom ends of the threaded rod pass through the fixed splint, and the outer surface of the bottom end of the threaded rod is threadedly connected to the movable splint;

[0008] The clamping mechanism includes a mounting frame, two sliding plates are installed on the inner side of the mounting frame, a rack is fixedly connected to the top of the mounting frame, a special-shaped gear is meshed with the top of the rack, and the top of the special-shaped gear is rotatably connected to the inner wall of the mounting frame.

[0009] Preferably, both sides of the fixed splint are fixedly connected with a first connecting block, and both ends of the movable splint are fixedly connected with a second connecting block.

[0010] Preferably, one end of the first connecting block and one end of the second connecting block are both rotatably connected to a linkage rod, and the two linkage rods are both rotatably connected.

[0011] Preferably, the top end of the threaded rod passes through the fixing frame, and the top end of the threaded rod is fixedly connected to a handle.

[0012] Preferably, a cylinder is installed on the top of the mounting frame, the bottom end of the cylinder passes through the mounting frame, and both sides of the bottom end of the mounting frame are fixedly connected with fixed blocks.

[0013] Preferably, one end of the fixing block is rotatably connected to a transmission rod, and one end of the transmission rod is rotatably connected to a connecting rod.

[0014] Preferably, the bottom end of the connecting rod is fixedly connected to the special-shaped gear, the inner side of the mounting frame is fixedly connected to a slide rail, the slide rail is slidably connected to the sliding plate, and the bottom of the sliding plate is fixedly connected to a movable plate.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:

[0016] 1. In the present invention, when the threaded rod rotates, it drives the movable clamping plate to gradually approach the fixed clamping plate, thereby firmly clamping the camera. At the same time, the rotation of the special-shaped gear cooperates with the rack to push the two sliding plates to move synchronously in the mounting frame. The two sliding plates drive the movable plate to clamp the camera from both sides, forming a double-layer positioning with the fixed clamping plate and the movable clamping plate. This design not only ensures the stability of the camera clamping, but also greatly improves the firmness of the fixation through the double-layer positioning. Even in complex environments, it can ensure that the camera is stably fixed on the drone, ensuring the smooth progress of the shooting mission.

[0017] 2. In the utility model, the handle is simply designed, which makes it easy for the user to rotate the threaded rod to drive the movable splint to move toward the fixed splint. The two linkage rods are connected between the fixed splint and the movable splint to ensure that the movable splint is stable and does not shake during lifting. The cylinder drives the fixed block to move in the mounting frame, thereby driving the transmission rod to move. The transmission rod rotates the special-shaped gear through the connecting rod, and the gear engages with the rack, thereby driving the two sliding plates to move synchronously on the preset track. The movement of the sliding plate drives the movable plate connected to it to clamp the camera from both sides, forming a double-layer clamping structure with the fixed splint and the movable splint, ensuring that the camera can be stably fixed on the drone even in complex environments. The entire operation process is simple and efficient, and the clamping is firm and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: Figures 1-4 As shown, the utility model provides a camera surveying and mapping fixing device for drones based on surveying and mapping services, comprising a mounting plate 1, with fixing brackets 2 fixedly connected to both sides of the bottom of the mounting plate 1, a positioning mechanism 3 installed at the bottom of the fixing brackets 2, and a clamping mechanism 4 installed between the two fixing brackets 2;

[0026] The positioning mechanism 3 includes a fixed clamping plate 32 and a movable clamping plate 34. The top of the fixed clamping plate 32 is fixedly connected to the bottom of the fixed frame 2. A threaded rod 33 is rotatably connected to one side of the fixed clamping plate 32. The top and bottom ends of the threaded rod 33 pass through the fixed clamping plate 32, and the outer surface of the bottom end of the threaded rod 33 is threadedly connected to the movable clamping plate 34.

[0027] The clamping mechanism 4 includes a mounting frame 41, two sliding plates 47 are installed inside the mounting frame 41, a rack 471 is fixedly connected to the top of the mounting frame 41, and the top of the rack 471 is meshed with a special-shaped gear 43, and the top of the special-shaped gear 43 is rotatably connected to the inner wall of the mounting frame 41.

[0028] The following describes the specific configuration and function of this embodiment. When the threaded rod 33 begins to rotate, due to the tight threaded connection between it and the movable clamping plate 34, this rotational motion is directly converted into linear movement of the movable clamping plate 34. As the threaded rod 33 continues to rotate, the movable clamping plate 34 gradually moves toward the fixed clamping plate 32.

[0029] As the movable clamping plate 34 and the fixed clamping plate 32 approach each other, the space between them gradually decreases, forming a stable clamping area. This clamping area is used to secure the camera. Because the surfaces of the fixed clamping plate 32 and the movable clamping plate 34 have been specially treated, they ensure sufficient friction with the camera surface, preventing the camera from slipping during the clamping process.

[0030] At the same time, when the special-shaped gear 43 begins to rotate, its teeth mesh with the grooves of the rack 471, exerting a horizontal force on the rack 471. This force propels the rack 471 horizontally within the mounting frame 41. The mounting frame 41 is designed with two symmetrical racks 471 and a sliding plate 47. This means that when one rack 471 moves, the other also moves simultaneously at the same speed and in the same direction. This simultaneous movement and proximity of the two sliding plates 47 provide an additional level of camera fixation.

[0031] As the two sliding plates 47 approach each other, they each drive their connected movable plates 44 to move. These two movable plates 44 clamp the camera from both sides, creating a double-layered positioning system with the fixed clamping plate 32 and movable clamping plate 34. This double-layered positioning design significantly enhances the camera's secure hold, ensuring it remains stably fixed to the drone even in complex flight environments.

[0032] Example 2: Figures 2-4As shown, both ends of the fixed splint 32 are fixedly connected to first connecting blocks 321, and both ends of the movable splint 34 are fixedly connected to second connecting blocks 341. A linkage rod 35 is rotatably connected to one end of the first connecting block 321 and one end of the second connecting block 341, and both linkage rods 35 are rotatably connected. The top end of the threaded rod 33 passes through the fixed frame 2 and is fixedly connected to the handle 31. A cylinder 42 is mounted on the top of the mounting frame 41, and the bottom end of the cylinder 42 passes through the mounting frame 41. Fixed blocks 45 are fixedly connected to both sides of the bottom end of the mounting frame 41. One end of the fixed block 45 is rotatably connected to a transmission rod 46, and one end of the transmission rod 46 is rotatably connected to a connecting rod 431. The bottom end of the connecting rod 431 is fixedly connected to the special-shaped gear 43. A slide rail 411 is fixedly connected to the inside of the mounting frame 41. The slide rail 411 is slidably connected to the sliding plate 47, and the bottom of the sliding plate 47 is fixedly connected to the movable plate 44.

[0033] The effect achieved by the whole embodiment is that, first, the handle 31 is designed to be easy for the user to operate, so that the user can easily rotate the threaded rod 33. When the threaded rod 33 rotates, it pushes the movable clamping plate 34 to move toward the fixed clamping plate 32 along a preset track.

[0034] To stably control the lifting and lowering of the movable clamping plate 34 and ensure smoothness during the clamping process, two linkage rods 35 are cleverly designed and installed between the fixed clamping plate 32 and the movable clamping plate 34. These linkage rods 35 are connected to a first connecting block 321 on the fixed clamping plate 32 and a second connecting block 341 on the movable clamping plate 34, respectively. When the movable clamping plate 34 is pushed by the threaded rod 33, the linkage rods 35 move accordingly, ensuring that the movable clamping plate 34 remains stable during the lifting and lowering process, preventing shaking or tilting.

[0035] The piston rod of the cylinder 42 is connected to the fixing block 45 . When the cylinder 42 is running, it drives the fixing block 45 to move inside the mounting frame 41 .

[0036] The movement of the fixed block 45 will drive the transmission rod 46 connected to it to move. The transmission rod 46 is connected to the special-shaped gear 43 through the connecting rod 431. The design of the special-shaped gear 43 allows it to rotate with its top as the center when it is subjected to the force of the connecting rod 431. The force is transmitted to the rack 471 that cooperates with the special-shaped gear 43. The rack 471 is fixed on the two sliding plates 47. When the rack 471 is subjected to the force of the special-shaped gear 43, it will drive the two sliding plates 47 to move simultaneously on the preset track, approaching or moving away from each other. The two sliding plates 47 are connected to the movable plate 44, so when the sliding plate 47 moves, the movable plate 44 will also move accordingly.

[0037] The device's usage and working principle are as follows: The handle 31 conveniently rotates the threaded rod 33, which in turn drives the movable clamping plate 34 to move, gradually bringing the movable clamping plate 34 closer to the fixed clamping plate 32. With the coordinated action of the fixed clamping plate 32 and the movable clamping plate 34, the camera is securely fixed.

[0038] During the process of the fixed splint 32 and the movable splint 34 approaching each other, the movement of the two linkage rods 35 ensures the coordinated work of the first connecting block 321 and the second connecting block 341, thereby stably controlling the lifting and lowering of the movable splint 34 and ensuring the stability of the clamping.

[0039] Furthermore, when the cylinder 42 operates, it drives the fixed block 45 within the mounting frame 41, thereby driving the movement of the transmission rod 46. The transmission rod 46 applies a force to the special-shaped gear 43 via the connecting rod 431, causing the special-shaped gear 43 to rotate about its top end. The rotation of the special-shaped gear 43 applies a force to the rack 471, causing it to move the two sliding plates 47 simultaneously within the mounting frame 41, bringing them closer together. In this way, the two moving plates 44 clamp and secure the camera on both sides, achieving double-layer positioning and enhancing the secure fixation.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
