Description

Technical Field

[0001] The present invention relates to the field of unmanned aerial vehicles (UAVs), and in particular to a fixing bracket for a camera carried by an UAV. Background Art

[0002] The camera mounting bracket of the drone is used to fix the camera and adjust the camera at multiple angles to meet the shooting requirements in different scenes. The existing technology uses a fixed bracket structure in which the base arm and the load arm are hinged (such as Figure 7 As shown in the figure, one end of the base arm is connected to the drone body, and the other end is connected to the payload arm through a hinge point. The end of the payload arm is installed with a camera. The relative rotation of the base arm and the payload arm at the hinge point can achieve the angle adjustment of the camera in the pitch, roll and other directions, thereby changing the shooting angle. However, this fixed bracket still has certain defects:

[0003] The base arm and payload arm structures also have limitations in terms of load capacity. Their overall rigidity is entirely dependent on the material and structural strength of the base arm and payload arm. When carrying a heavy camera, the base arm and payload arm must withstand large torques, which can easily cause deformation. Long-term heavy-load use can lead to increased wear at the hinge points, and even problems such as bending and breaking of the arms, which can cause the camera angle to shift and affect shooting accuracy. In addition, when adjusting the camera angle, the force points of the base arm and payload arm will change with the angle, further reducing the stability of the structure. This makes it difficult to maintain a reliable fixation when the bracket bears heavy loads or has a large angle adjustment range.

[0004] In terms of stability, its anti-shake ability is relatively weak, and it mainly relies on the damping parts at the hinge points for passive buffering. Since the drone will be affected by various external forces such as vibrations generated by the rotation of the propeller and airflow disturbances during flight, these vibrations will be directly transmitted to the camera through the base arm and the load arm. The buffering effect of the damping parts is limited and cannot actively offset vibrations of different frequencies and intensities, causing the pictures taken by the camera to be prone to shaking and blurring. Especially in high-speed flight or complex airflow environments, the stability of the picture is difficult to guarantee. Summary of the Invention

[0005] In view of the problem mentioned above or in the prior art that the overall rigidity depends on the material and structural strength of the base arm and the load arm, the present invention is proposed.

[0006] Therefore, an object of the present invention is to provide a camera fixing bracket for an unmanned aerial vehicle.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a camera fixing bracket for a drone, used for installing and fixing a camera, comprising:

[0008] The drone itself;

[0009] A fixing portion provided on the drone body, the fixing portion comprising:

[0010] An adjustment component for installing and adjusting the camera, a three-dimensional locking component is arranged between the adjustment component and the drone body, and the three-dimensional locking component is used to construct a three-dimensional locking and fixing structure for the camera between the adjustment component and the drone body; an adjustment reinforcement component for limiting and reinforcing the camera angle adjustment is arranged between the adjustment component and the camera, and the adjustment reinforcement component is locked and connected with the three-dimensional locking and fixing structure to form an integrated fixing structure of the three-dimensional locking component, the adjustment component and the adjustment reinforcement component.

[0011] As a preferred solution of the present invention, a fixing bracket for a camera mounted on a drone, wherein: a base groove is opened on the drone body, the adjustment component includes a base fixedly installed in the base groove, and a rotating frame is rotatably installed on the side of the base away from the drone body.

[0012] As a preferred solution of the camera fixing bracket for an unmanned aerial vehicle of the present invention, two mounting heads that are symmetrical to each other along the axial direction of the base are fixedly mounted on the rotating frame, a rotating seat is rotatably mounted between the two mounting heads, and the camera is fixedly mounted between the two rotating seats.

[0013] As a preferred solution of a camera fixing bracket for an unmanned aerial vehicle of the present invention, the three-dimensional locking assembly includes two hinged rods hinged on the outside of the mounting head and symmetrical to each other along the axial direction of the mounting head, an annular groove is provided on the outside of the base, and a slider is slidably installed in the annular groove.

[0014] As a preferred solution of a camera fixing bracket for an unmanned aerial vehicle of the present invention, a connecting rod is fixedly installed on the side of the slider away from the annular groove, a threaded hole is provided at the end of the connecting rod, and the ends of the two corresponding hinged rods on the two mounting heads are fixed to the threaded holes by short bolts.

[0015] As a preferred solution of the camera fixing bracket for an unmanned aerial vehicle of the present invention, the three-dimensional locking assembly also includes two long bolts, which sequentially pass through the ends of the hinge shafts of the hinged rods on the two mounting heads and are fastened and fixed by nuts to form a three-dimensional triangular locking and fixing structure.

[0016] As a preferred solution of the camera fixing bracket for a drone of the present invention, the adjustment reinforcement component includes a slide rail fixedly mounted on a side of the rotating frame away from the drone body, and a slider 2 is slidably mounted in the slide rail.

[0018] As a preferred solution of the camera fixing bracket for a drone of the present invention, the long bolt also passes through the end of the slide rail to form an integrated interlocking fixing structure of the hinge rod, the long bolt and the slide rail.

[0019] The beneficial effects of the camera fixing bracket for a drone of the present invention are as follows:

[0020] In the present application, a three-dimensional triangular locking and fixing structure is constructed through the coordinated design of the adjustment component, the three-dimensional locking component and the adjustment reinforcement component. The long bolt passes through the end of the hinge shaft of the hinged rod and through the through hole at the end of the slide rail. After being locked by the nut, the slide rail, the hinged rod and the long bolt are tightly connected as a whole, forming a triangular stable structure to form a force transmission closed loop. When the camera is subjected to vibration or load, the force can be transmitted to the long bolt through the reinforcement rod, the slider 2, and the slide rail, and then dispersed to the hinge rod and the base by the long bolt, realizing multi-path transmission of force in the entire bracket system. At the same time, this integrated locking effectively avoids the gap between the adjustment reinforcement component and other components due to angle adjustment, ensuring that when the camera angle changes, the components can still maintain a rigid connection, jointly resist deformation, and maintain the stability of the overall structure.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Reference Figures 1 to 6 The present embodiment provides a camera fixing bracket for a drone, which can achieve the effect of multi-path force transmission in the entire bracket system and is used to install and fix a camera 3. The bracket includes a drone body 1; a fixing portion 2 is provided on the drone body 1, and the fixing portion 2 includes an adjustment component 21 for installing and adjusting the camera 3. A three-dimensional locking component 22 is provided between the adjustment component 21 and the drone body 1. The three-dimensional locking component 22 is used to construct a three-dimensional locking and fixing structure for the camera 3 between the adjustment component 21 and the drone body 1; an adjustment reinforcement component 23 is provided between the adjustment component 21 and the camera 3 for limiting and reinforcing the angle adjustment of the camera 3, and the adjustment reinforcement component 23 is locked and connected to the three-dimensional locking and fixing structure to form an integrated fixing structure of the three-dimensional locking component 22, the adjustment component 21 and the adjustment reinforcement component 23.

[0032] Reference Figures 1 to 6 A base groove 4 is provided on the drone body 1 , and the adjustment component 21 includes a base 211 fixedly installed in the base groove 4 , and a rotating frame 212 is rotatably installed on a side of the base 211 away from the drone body 1 .

[0033] Reference Figures 1 to 6 Two mounting heads 213 symmetrical to each other along the axial direction of the base 211 are fixedly mounted on the rotating frame 212 , a rotating seat 214 is rotatably mounted between the two mounting heads 213 , and the camera 3 is fixedly mounted between the two rotating seats 214 .

[0034] It should be noted that the base groove 4 is a groove machined into the surface of the drone body 1, preferably a circular groove with a depth designed to accommodate the installation of the base 211. The base 211 is a rigid support component that matches the shape of the base groove 4. Specifically, it is made of aluminum alloy and is fixed to the base groove 4 by a snap-fit ​​mechanism. The rotating frame 212 is a C-shaped frame structure with a rotating shaft, which is used to support the camera 3.

[0035] The mounting head 213 is a supporting structure arranged on both sides of the rotating frame 212. The mounting head 213 has a built-in rotating motor for driving the rotating seat 214 to rotate to adjust the shooting angle of the camera 3. Specifically, an aluminum alloy casting can be used. Its symmetrical arrangement can form a more stable support base to disperse the load of the camera 3.

[0036] Reference Figures 1 to 6 The three-dimensional locking assembly 22 includes two hinged rods 221 hinged on the outside of the mounting head 213 and symmetrical to each other along the axial direction of the mounting head 213. An annular groove 222 is provided on the outside of the base 211, and two sliders 223 are slidably installed in the annular groove 222.

[0037] Reference Figures 1 to 6 A connecting rod 224 is fixedly installed on the side of the slider 223 away from the annular groove 222. A threaded hole 226 is opened at the end of the connecting rod 224. The ends of the two corresponding hinged rods 221 on the two mounting heads 213 are fixed to the threaded holes 226 through short bolts 225.

[0038] It should be noted that the hinged rod 221 is a rod-shaped component connected to the outside of the mounting head 213 by a hinged manner, and is used to form an adjustable support connection between the mounting head 213 and the base 211; the annular groove 222 is an annular groove structure opened on the outside of the base 211, which is used to provide a sliding path for the slider 223 to adapt to mutual angle adjustment and greatly improve the support and stability of the rotating frame 212. The slider 223 is a block-shaped component that slides with the annular groove 222. Specifically, a metal block with a protrusion or roller can be embedded in the annular groove 222 to slide, so as to establish a movable connection point between the base 211 and the hinged rod 221.

[0039] The connecting rod 224 is a rigid component connecting the slider 223 and the hinged rod 221. It can be made of aluminum alloy and is used to transmit the locking force and construct a multi-directional force structure. The threaded hole 226 is a threaded interface set at the end of the connecting rod 224, which is used to cooperate with the short bolt 225 to form a detachable mechanical locking connection. The short bolt 225 is screwed into the threaded hole 226 to fix the end of the hinged rod 221 and the connecting rod 224 as a whole.

[0040] Reference Figures 1 to 6The three-dimensional locking assembly 22 also includes two long bolts 227, which sequentially penetrate the ends of the hinge shafts of the hinge rods 221 on the two mounting heads 213 and are fastened and fixed by nuts to form a three-dimensional triangular locking and fixing structure.

[0041] It should be noted that the long bolt 227 is a rod-shaped fastener with a thread at the end, which is used to pass through the hinge shafts of multiple hinged rods 221 and apply axial pressure through a nut to form a rigid connection; the end of the hinge shaft of the hinged rod 221 is machined into a through hole for the long bolt 227 to pass through; the nut is locked and fixed by rotating the nut so that it engages with the thread of the long bolt 227. Specifically, a anti-loosening nut can be used to eliminate the connection gap and maintain the locking force.

[0042] Reference Figures 1 to 6 The adjustment reinforcement component 23 includes a slide rail 231 fixedly mounted on the side of the rotating frame 212 away from the drone body 1, and a slider 232 is slidably mounted in the slide rail 231.

[0043] Reference Figures 1 to 6 A reinforcing rod 233 is fixedly installed on the side of the slider 232 away from the drone body 1, and the end of the reinforcing rod 233 is fixedly connected to the camera 3.

[0044] Reference Figures 1 to 6 The long bolt 227 also passes through the end of the slide rail 231, forming an integrated mutually locking and fixing structure of the hinge rod 221, the long bolt 227 and the slide rail 231.

[0045] It should be noted that the slide rail 231 is a rail arranged along the extension direction of the rotating frame 212. Specifically, it can be made of aluminum alloy and processed into a guide rail with a T-slot, which is used to provide a sliding path for the slider 232 and limit its freedom of movement. The direction of the slide groove on the slide rail 231 is consistent with the direction in which the rotating seat 214 drives the camera 3 to adjust the angle.

[0046] Slider 232 is a sliding component that cooperates with the slide rail 231. Specifically, a sliding block structure with a ball bearing can be adopted. The balls embedded inside can reduce the sliding friction resistance while maintaining close contact with the slide rail 231. The end of the slide rail 231 is also provided with a through hole for cooperating with the long bolt 227 to form an integrated locking fixation.

[0047] During specific use, first place the camera 3 to be fixed between the two rotating seats 214, and firmly connect the camera 3 to the rotating seat 214 through the matching fixing parts to ensure that the camera 3 will not loosen or deviate during subsequent operations. Then, rotate the slider 223 in the annular groove 222 on the outer side of the base 211 so that the connecting rod 224 is parallel to the ground; then rotate the hinge rod 221 so that the ends of the corresponding two hinge rods 221 are aligned with the threaded holes 226 at the ends of the connecting rod 224; after alignment, pass the short bolt 225 through the ends of the hinge rod 221 and screw it into the threaded hole 226, and tighten the short bolt 225 to achieve rigid fixation of the hinge rod 221 and the connecting rod 224, completing the preliminary connection between the three-dimensional locking assembly 22 and the adjustment assembly 21;

[0048] Then, the end of the reinforcing rod 233 is connected to the camera 3 to ensure that the reinforcing rod 233 forms a stable support for the camera 3; at this time, the slider 232 can slide freely in the slide rail 231 to adapt to the position change during the subsequent angle adjustment of the camera 3; then take two long bolts 227, and vertically pass the long bolts 227 through the ends of the two hinge shafts and the through holes at the end of the slide rail 231 in turn. After passing through, the long bolts 227 are threaded and fixed with nuts to form a triangular locking and fixing structure integrating the three-dimensional locking component 22, the adjustment component 21 and the adjustment reinforcement component 23.

[0049] When the camera 3 is adjusted in pitch via the swivel mount 214 or in roll with the turret 212, the second slider 232 slides synchronously within the slide rail 231. The slide rail 231's positional limiter, aligning with the camera 3's angular trajectory, ensures that the reinforcing rod 233 maintains a stable connection to the camera 3, creating an additional support point in addition to the swivel mount 214. When the camera 3 generates torque due to its own weight or flight vibrations, the reinforcing rod 233 transfers some of the force to the second slider 232, which then transmits it to the turret 212 via the slide rail 231, distributing it throughout the adjustment assembly 21 and effectively reducing the load on the swivel mount 214. Even during camera 3 angle adjustment, the second slider 232's synchronous movement with the slide rail 231 allows the length and angle of the reinforcing rod 233 to dynamically adapt to changes in the camera 3's position, maintaining rigid support for the camera 3 and preventing support failure due to angular deviation. This enhances the stability of the camera 3 in various shooting postures.

[0050] In addition, the long bolt 227 is designed to pass through the end of the slide rail 231. The long bolt 227 not only passes through the end of the hinge axis of the hinge rod 221, but also extends through the through hole at the end of the slide rail 231. After being tightened by the nut, the slide rail 231, the hinge rod 221 and the long bolt 227 are tightly connected as a whole, so that the adjustment reinforcement assembly 23 is no longer an independent supporting structure, but forms a force transmission closed loop with the triangular stable structure of the three-dimensional locking assembly 22. When the camera 3 is subjected to vibration or load, the force can be transmitted to the long bolt 227 through the reinforcement rod 233, the slider 232, and the slide rail 231, and then dispersed to the hinge rod 221 and the base 211 by the long bolt 227, thereby realizing multi-path transmission of force in the entire bracket system. At the same time, this integrated locking effectively avoids the gap between the adjustment reinforcement assembly 23 and other components due to angle adjustment, ensuring that when the angle of the camera 3 changes, the various components can still maintain a rigid connection, jointly resist deformation, and maintain the stability of the overall structure.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
