Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) supporting equipment technology, and in particular to a lift-stabilized three-axis zoom night vision gimbal. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control devices or onboard computer control systems. UAV aerial imagery offers advantages such as high definition, large scale, small area coverage, and high timeliness, making it particularly suitable for acquiring aerial images of strip-shaped areas, such as highways, railways, rivers, and reservoirs. However, in practical applications, due to their relatively light weight, UAVs experience vibrations during takeoff and landing, resulting in shaky footage, ghosting, and affecting the recording of aerial images. Furthermore, existing technologies often require cameras suitable for capturing clear images with automatic zoom and night vision capabilities to be mounted independently, raising questions about how to integrate them onto UAVs. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a stable three-axis zoom night vision gimbal. By setting a top plate and connecting screw holes at the top of the fixed frame, the entire fixed frame is fixed to the lower side of the drone, supporting the three-axis gimbal and zoom night vision camera. The three-axis gimbal is detachably connected to the fixed frame, facilitating user assembly and disassembly. The fixed frame is equipped with upper and lower shock-absorbing plates connected by springs, which alleviate the inertia and potential energy generated during lifting, thus providing shock absorption and improving the stability of the entire night vision platform. Correspondingly, the three-axis gimbal itself, used to fix the zoom night vision camera, also plays a role in stabilizing the viewing angle, automatically adjusting the camera's position according to acceleration and center of gravity shift. A lifting counterweight is also provided on the side of the fixed frame, adjusting the center of gravity of the fixed frame during lifting to ensure the balance of the entire gimbal.

[0005] This utility model provides a lifting and stabilizing three-axis zoom night vision gimbal, including a fixed frame with a top plate and an extension plate, a shock-absorbing component disposed within the fixed frame, a three-axis gimbal sandwiched between the shock-absorbing components, and a detachable zoom night vision camera disposed on the three-axis gimbal.

[0006] The top plate is provided with fixing screw holes, and an L-shaped extension plate extends downward from the side of the top plate. The top plate and the extension plate cooperate to form a U-shaped structure. The shock absorption assembly includes an upper shock absorption plate, a lower shock absorption plate, and springs. Several springs are provided on the lower side of the top plate, and the top plate is connected to the upper shock absorption plate through the springs. Several springs are also provided on the bottom side of the extension plate, and the extension plate is connected to the lower shock absorption plate through the springs. The upper and lower shock absorption plates are both located within the fixed frame, and the three-axis gimbal is sandwiched between the upper and lower shock absorption plates.

[0007] The included mounting holes allow for screw connection to a drone, securing it to the bottom for night vision monitoring. The top plate and extension plate form a U-shaped structure, providing support for the three-axis gimbal. Since the drone vibrates during ascent and descent, causing shaky footage, a buffer component is added. Springs alleviate the inertia and potential energy generated during ascent and descent, thus reducing vibration and improving the overall stability of the night vision platform. The three-axis gimbal, sandwiched between these damping components, stabilizes the zoom night vision camera, ensuring stable footage. The zoom night vision camera is a pre-existing technology; its internal structure is described in detail here.

[0008] In some embodiments, the upper shock absorber plate has a through hole in the middle, and the position of the fixing screw hole corresponds to the through hole. The spring on the upper shock absorber plate is arranged around the through hole. The through hole provides space for the operator to install screws to fix the top plate. The operator can pass through the through hole and fix the top plate to the bottom of the drone with screws. At the same time, the through hole reduces the weight of the entire upper shock absorber plate, making it easier for the drone to carry and fly. The spring arranged around the through hole makes the upper shock absorber plate elastic, which plays a role in cushioning and shock absorption.

[0009] In some embodiments, a pressing plate extends upward from the side of the lower shock absorber, and the pressing plate has a pressing surface that is parallel to the bottom side of the extension plate and extends beyond the fixed frame. The pressing plate and pressing surface facilitate the operator in securing the three-axis gimbal in the middle of the shock absorber assembly. By pressing down on the pressing plate, the operator lowers it and inserts the battery compartment between the upper and lower shock absorbers. After rebounding, the two shock absorbers automatically fix the three-axis gimbal. When the three-axis gimbal needs to be removed, the pressing plate is pressed down again, and the battery compartment can be moved out from the side plate.

[0010] In some embodiments, the lower damping plate is provided with a lower through hole, and the extension plate has a groove on its bottom side. The position of the lower through hole corresponds to the position of the groove, and the spring on the bottom side of the extension plate is disposed on both sides of the groove. The lower through hole and the groove are both used to reduce weight and facilitate carrying by the drone. The spring disposed around the groove makes the lower damping plate elastic, realizing downward pressure and rebound.

[0011] In some embodiments, a sliding groove is provided on the side of the extension plate, and a movable lead screw is provided in the sliding groove. A movable counterweight is slidably connected to the movable lead screw, and the movable counterweight extends outside the fixed frame. The sliding groove is provided to accommodate the movable lead screw and the movable counterweight. The movable counterweight is used to balance the weight on both sides of the fixed frame. Since the three-axis gimbal and the carried zoom night vision camera are relatively heavy, imbalance often occurs during lifting. Therefore, a liftable counterweight is provided on the other side. The center of gravity of the entire fixed frame is adjusted by lifting and moving the counterweight, thereby maintaining stability during lifting and lowering. It should be understood that controlling when the movable counterweight lifts and lowers and the height of lifting and lowering can be obtained through multiple experiments, which will not be elaborated here.

[0012] In some embodiments, the three-axis gimbal includes a battery compartment, a three-axis moving rod, and a telescopic frame. The three-axis moving rod is located on the side of the battery compartment, and the telescopic frame is located at the end of the three-axis moving rod. The battery compartment is secured in the shock-absorbing assembly, and the zoom night vision camera is secured within the telescopic frame. The battery compartment is electrically connected to the three-axis moving rod to supply power to it. The specific structure and rotation direction of the three-axis moving rod can refer to existing technologies. The telescopic frame at the end of the three-axis moving rod is used to fix the zoom night vision camera. The telescopic design facilitates the loading and unloading of the zoom night vision camera by operators.

[0013] In some embodiments, the battery compartment is provided with a magnetic adsorption strip on the side near the fixed frame, and the side of the extension plate is provided with a corresponding metal strip, or the extension plate itself is made of metal. The magnetic adsorption strip is used to improve the stability of the connection between the three-axis gimbal and the fixed frame. The extension plate can be provided with a metal strip at the corresponding position for adsorption, or the extension plate can be made of a metal material that facilitates adsorption.

[0014] In some embodiments, the three-axis moving rod includes a first electrically driven rotary axis, a first support rod, a second electrically driven rotary axis, a second support rod, a third electrically driven rotary axis, and a third support rod. The first electrically driven rotary axis is disposed between the battery compartment and the first support rod; the second electrically driven rotary axis is disposed between the first support rod and the second support rod; and the third electrically driven rotary axis is disposed between the second support rod and the third support rod. The telescopic frame is disposed on the third support rod. The above-described specific structure of the three-axis moving rod is prior art. The three-axis moving rod is also provided with other components such as an accelerometer and a gyroscope. By sensing changes in acceleration and angular deviations of the gyroscope, the corresponding electrically driven rotary axis is adjusted to achieve stable shooting of the camera in the air and improve the overall operational stability of the gimbal.

[0015] In some embodiments, a left-side fixing frame extends from one end of the third support rod. A telescopic spring is installed inside the third support rod, with one end connected to the inside of the third support rod and the other end connected to a telescopic rod. The third support rod is sleeved on the outside of the telescopic rod, and the end of the telescopic rod is connected to a right-side fixing frame. The left fixing frame is located near the third electric drive rotating shaft, while the right fixing frame is located on the other side of the third support rod. A telescopic rod, fixed by a spring, is installed inside the third support rod. When it cooperates with the right fixing frame, it enables the extension and retraction of the right fixing frame, thereby securing the camera.

[0016] In some embodiments, both the left and right fixed frames are provided with L-shaped load-bearing brackets extending downwards. Since the zoom night vision camera is relatively heavy, fixing it solely with the side fixed frames can easily cause the camera to tilt during lifting and lowering. Therefore, adding auxiliary L-shaped load-bearing brackets limits the position of the zoom night vision camera, thereby improving stability.

[0017] By adopting the above technical solution, the beneficial effects of this utility model are:

[0018] This invention uses a top plate with screw holes at the top of a fixed frame to fix the entire frame to the underside of the drone, supporting a three-axis gimbal and a zoom night vision camera. The three-axis gimbal is detachably connected to the fixed frame for easy installation and removal. The fixed frame is equipped with upper and lower shock-absorbing plates connected by springs to mitigate the inertia and potential energy generated during lifting, thus reducing vibration and improving the stability of the entire night vision platform. Correspondingly, the three-axis gimbal used to fix the zoom night vision camera also stabilizes the viewing angle and can automatically adjust the position of the camera according to acceleration and center of gravity shift. The fixed frame also has lifting counterweights on the side to adjust the center of gravity of the fixed frame during lifting, ensuring the balance of the entire gimbal.

[0043] Reference Figure 1 , Figure 1 This is a disassembly diagram of the various parts of the night vision gimbal in some embodiments of this utility model.

[0044] According to some embodiments of the present invention, the present invention provides a lifting and stabilizing three-axis zoom night vision gimbal, including a fixed frame 1 with a top plate 11 and an extension plate 12, a shock-absorbing component 2 disposed in the fixed frame 1, a three-axis gimbal 3 sandwiched between the shock-absorbing components 2, and a zoom night vision camera 4 detachably disposed on the three-axis gimbal 3.

[0045] The top plate 11 is provided with fixing screw holes, and an L-shaped extension plate 12 extends downward from the side of the top plate 11. The top plate 11 and the extension plate 12 cooperate to form a U-shaped structure. The shock absorption assembly 2 includes an upper shock absorption plate 21, a lower shock absorption plate 22 and springs 23. Several springs 23 are provided on the lower side of the top plate 11. The top plate 11 is connected to the upper shock absorption plate 21 through the springs 23. Several springs 23 are also provided on the bottom side of the extension plate 12. The extension plate 12 is connected to the lower shock absorption plate 22 through the springs 23. The upper shock absorption plate 21 and the lower shock absorption plate 22 are both located in the fixed frame 1. The three-axis gimbal 3 is sandwiched between the upper shock absorption plate 21 and the lower shock absorption plate 22.

[0046] The fixed screw holes are designed to be screwed in with screws for docking with and fixing the drone to the bottom, enabling night vision monitoring via the drone. The top plate 11 and the extension plate 12 cooperate to form a U-shaped structure, which serves to fix and support the three-axis gimbal 3. Since the drone body will shake during the ascent and descent, resulting in corresponding shaking of the captured image, a buffer component is added. The spring 23 alleviates the inertia and potential energy generated during the ascent and descent, thereby playing a shock-absorbing role and improving the stability of the entire night vision platform. The three-axis gimbal 3, sandwiched between the shock-absorbing component 2, plays a role in stabilizing and fixing the zoom night vision camera 4, making its captured image stable. The zoom night vision camera 4 is a camera that already exists in the prior art. The specific internal structure can be referred to in the prior art, and will not be described in detail here.

[0047] The extension plate 12 has a sliding groove 14 on its side, and a movable lead screw is installed in the sliding groove 14. A movable counterweight 15 is slidably connected to the movable lead screw, and the movable counterweight 15 extends outside the fixed frame 1. The sliding groove 14 is used to accommodate the movable lead screw and the movable counterweight 15. The movable counterweight is used to balance the weight on both sides of the fixed frame 1. Since the three-axis gimbal 3 and the carried zoom night vision camera 4 are relatively heavy, imbalance often occurs during lifting and lowering. Therefore, a liftable counterweight is set on the other side to adjust the center of gravity of the entire fixed frame 1 by lifting and lowering, thereby maintaining stability during lifting and lowering. It should be understood that controlling when the movable counterweight 15 lifts and lowers and the height of lifting and lowering can be obtained through multiple experiments, which will not be elaborated here.

[0048] The three-axis gimbal 3 includes a battery compartment 31, a three-axis moving rod 32, and a telescopic frame 33. The three-axis moving rod 32 is located on the side of the battery compartment 31, and the telescopic frame 33 is located at the end of the three-axis moving rod 32. The battery compartment 31 is fitted into the shock-absorbing assembly 2, and the zoom night vision camera 4 is fitted inside the telescopic frame 33. The battery compartment 31 is electrically connected to the three-axis moving rod 32 to supply power to the three-axis moving rod 32. The specific structure and rotation direction of the three-axis moving rod 32 can refer to the prior art. The telescopic frame 33 at the end of the three-axis moving rod 32 is used to fix the zoom night vision camera 4. The telescopic design facilitates the loading and unloading of the zoom night vision camera 4 by the operator.

[0049] The battery compartment 31 is provided with a magnetic adsorption strip 34 on the side near the fixed frame 1, and the extension plate 12 is provided with a metal strip on its side, or the extension plate 12 itself is made of metal. The magnetic adsorption strip 34 is used to improve the stability of the connection between the three-axis gimbal 3 and the fixed frame 1. The extension plate 12 can be provided with a metal strip at the corresponding position for adsorption, or the extension plate 12 can be made of a metal material that is easy to adsorb.

[0050] The three-axis moving rod 32 includes a first electric drive rotary axis, a first support rod, a second electric drive rotary axis, a second support rod, a third electric drive rotary axis, and a third support rod. The first electric drive rotary axis is disposed between the battery compartment 31 and the first support rod; the second electric drive rotary axis is disposed between the first support rod and the second support rod; and the third electric drive rotary axis is disposed between the second support rod and the third support rod. The telescopic frame 33 is disposed on the third support rod. The above-described specific structure of the three-axis moving rod 32 is prior art. The three-axis moving rod 32 is also provided with other components such as an accelerometer and a gyroscope. By sensing changes in acceleration and angular deviations of the gyroscope, the corresponding electric drive rotary axis is adjusted to achieve stable shooting of the camera in the air and improve the overall operational stability of the gimbal.

[0051] The third support rod extends to one end and is equipped with a left-side fixing frame 331. A telescopic spring is installed inside the third support rod, with one end connected to the inside of the third support rod and the other end connected to a telescopic rod. The third support rod is fitted over the telescopic rod, and the end of the telescopic rod is connected to a right-side fixing frame 332. The left fixing frame is located near the third electric drive rotating shaft, while the right fixing frame is located on the other side of the third support rod. A telescopic rod, fixed by a spring 23, is installed inside the third support rod. When this telescopic rod cooperates with the right fixing frame, it allows the right fixing frame to extend and retract, thereby securing the camera.

[0052] Both the left fixed frame 331 and the right fixed frame 332 have L-shaped load-bearing frames extending downwards. Because the zoom night vision camera 4 is quite heavy, fixing it only with the side fixed frames can easily cause the camera to tilt during lifting. Therefore, an auxiliary L-shaped load-bearing frame is added to limit the position of the zoom night vision camera 4, thereby improving stability.

[0053] Reference Figure 2 , Figure 2 This is a schematic diagram of the internal structure of the fixed frame in some embodiments of the present invention.

[0054] According to some embodiments of this utility model, optionally, the upper shock-absorbing plate 21 has an upper through hole 24 in the middle, and the position of the fixing screw hole corresponds to the upper through hole 24. The spring 23 on the upper shock-absorbing plate 21 is arranged around the upper through hole 24. The upper through hole 24 provides space for the operator to install screws to fix the top plate 11. The operator can pass through the upper through hole 24 and fix the top plate 11 to the bottom of the drone with screws. At the same time, the upper through hole 24 reduces the weight of the entire upper shock-absorbing plate 21, making it easier for the drone to carry and fly. The spring 23 arranged around the through hole makes the upper shock-absorbing plate 21 elastic, playing a role in buffering and shock absorption.

[0055] A pressing plate 25 extends upward from the side of the lower shock absorber 22. The pressing plate 25 has a pressing surface that is parallel to the bottom side of the extension plate 12 and extends beyond the fixed frame 1. The pressing plate 25 and pressing surface allow operators to easily position the three-axis gimbal 3 within the shock absorber assembly 2. By pressing down on the pressing plate 25, the operator lowers it and inserts the battery compartment 31 between the upper and lower shock absorbers 22. After rebounding, the two shock absorbers automatically secure the three-axis gimbal 3. To remove the three-axis gimbal 3, the pressing plate 25 is pressed down again, allowing the battery compartment 31 to be moved out from the side plate.

[0056] The lower damping plate 22 is provided with a lower through hole 26, and the extension plate 12 has a groove 13 on its bottom side. The position of the lower through hole 26 corresponds to the position of the groove 13. The spring 23 on the bottom side of the extension plate 12 is provided on both sides of the groove 13. The lower through hole 26 and the groove 13 are both provided to reduce weight and facilitate the carrying of the drone. The spring 23 provided around the groove 13 makes the lower damping plate 22 elastic, realizing downward pressure and rebound.

Therefore, phrases or "embodiments" appearing in various places throughout the specification do not necessarily refer to the same embodiment.
