Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle (UAV) technology, and in particular relates to a UAV lifting gimbal. Background Technology

[0002] In a wide range of applications such as drone aerial photography, geological surveying, power line inspection, and agricultural plant protection, the gimbal, as a core component carrying precision shooting and sensing equipment such as cameras and lidar, directly determines the quality and effectiveness of the acquired data. However, during drone flight, especially when encountering complex airflow, performing maneuvers, or cruising at high speeds, the operation of the drone's engine and aerodynamic effects cause continuous vibrations in the aircraft. These vibrations are transmitted to the gimbal through the fuselage structure, resulting in blurred and shaky images, distorted sensor data, and severely impacting operational effectiveness.

[0003] While existing drone gimbal vibration reduction devices offer some protection, they still suffer from several shortcomings that require further investigation. First, the transmission and support structures of some devices are poorly designed, failing to effectively optimize the transmission path of vibration energy. This results in significant vibration still being transmitted to the camera, leading to inadequate vibration reduction. Second, many gimbal devices prioritize structural strength, resulting in an overall bulky design. This increases flight time and maneuverability, negatively impacting the drone's payload capacity and flight performance.

[0004] Therefore, a drone lifting gimbal is proposed. Summary of the Invention

[0010] In the drone lifting gimbal of the present invention, at least one adjustment slot for installing the tension wheel shaft is provided on the star-shaped connecting plate. The tension wheel shaft is fixedly installed in the adjustment slot by a locking nut. A tension wheel is coaxially rotatably connected to the tension wheel shaft, and the outer edge of the tension wheel abuts against the belt. The tension wheel shaft is locked in different positions in the adjusting slot by tightening the lock nut, so as to adjust the tension of the belt by the tension wheel.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 7 The present invention discloses a drone lifting gimbal, comprising: a gimbal outer frame 100, a transmission lifting mechanism 200, and a shock absorption mechanism 300; The transmission lifting mechanism 200 includes a star-shaped connecting plate 7, a drive assembly, and multiple lifting assemblies 400. The multiple lifting assemblies 400 are circumferentially spaced on the star-shaped connecting plate 7. The star-shaped connecting plate 7 is fixedly connected to the outer frame 100 of the gimbal. The drive assembly is located on the star-shaped connecting plate 7 and is connected to the input end of the multiple lifting assemblies 400. The lifting assembly 400 includes a lead screw 16 and a nut 17; the lead screw 16 is connected to the drive assembly for transmission; the nut 17 is threadedly engaged with the lead screw 16, and multiple nuts 17 are connected to the shock absorber mounting plate 21. The shock absorption mechanism 300 includes a pod base 23 and multiple shock absorption elements 20; the pod base 23 is mounted on the shock absorber fixing plate 21 and is used to mount the photoelectric pod 24; the multiple shock absorption elements 20 are disposed between the shock absorber fixing plate 21 and the pod base 23. The outer frame 100 of the gimbal has a hollow structure to reduce weight.

[0021] When the height of the optoelectronic pod 24 needs to be adjusted, the drive assembly is activated, driving the lead screws 16 of multiple lifting components 400 to rotate synchronously. Nuts 17, threaded to the lead screws 16, then move linearly. Since multiple nuts 17 are connected to the shock absorber mounting plate 21, this drives the entire shock absorber mechanism 300 and the optoelectronic pod 24 to rise and fall smoothly. During this process, multiple shock absorber elements 20 positioned between the shock absorber mounting plate 21 and the pod base 23 effectively buffer vibrations from all directions. This invention achieves stable lifting and lowering of the gimbal through an integrated transmission lifting mechanism 200. The shock absorber mechanism 300 acts directly on the load-bearing platform, providing effective vibration isolation. Simultaneously, the hollow structure on the outer frame 100 of the gimbal reduces the overall weight while maintaining strength.

[0022] In one alternative embodiment, the drive assembly includes a motor 13, which is fixedly mounted on a star-shaped connecting plate 7. The output end of the motor 13 is coaxially fixed to a drive wheel 8. The drive wheel 8 is driven by a belt 14 to a plurality of driven wheels 9. The plurality of driven wheels 9 are rotatably connected to the star-shaped connecting plate 7 and are circumferentially spaced. The top ends of a plurality of lead screws 16 are correspondingly and coaxially fixed to the plurality of driven wheels 9.

[0023] In use, the motor 13 drives the drive wheel 8 to rotate, which in turn drives multiple driven wheels 9 arranged at equal intervals around the circumference to rotate synchronously via the belt 14. This drives multiple lead screws 16 that are coaxially fixed to the driven wheels 9 to rotate, ensuring that the power is transmitted evenly and synchronously to all lifting components 400, thus achieving the smoothness and consistency of the lifting process.

[0024] In one alternative embodiment, the lifting assembly 400 further includes a guide rail 19, with two bearing seats 25 fixedly connected to one side of the guide rail 19. The two bearing seats 25 are located at both ends of the guide rail 19 respectively. The lead screw 16 is rotatably connected to the two bearing seats 25 through two bearings 12. A slider 18 is slidably connected to the guide rail 19, and the slider 18 is fixedly connected to the nut 17 through a U-shaped block 15.

[0025] When the lead screw 16 rotates and drives the nut 17 to move, the nut 17 drives the slider 18 to slide along the fixed guide rail 19 via the U-shaped block 15. The guide rail 19 and the bearing seat 25 that supports the lead screw 16 via the bearing 12 work together to provide precise guidance and stable rotational support for the lifting motion, effectively preventing the nut 17 and slider 18 from deflecting or jamming during the movement, and ensuring the linearity and stability of the lifting.

[0026] In one alternative, the shock absorber mounting plate 21 has multiple shock absorber holes 26, which are evenly spaced around the periphery. The top of the shock absorber element 20 is installed in the shock absorber hole 26, and the bottom of the multiple shock absorber elements 20 is connected to the pod base 23.

[0027] When the gimbal is in operation, vibration energy is transmitted to the damper mounting plate 21, causing the damping elements 20 within the circumferentially spaced damping holes 26 to undergo elastic deformation. This arrangement ensures that the damping elements 20 are evenly stressed, more effectively absorbing and dissipating vibration energy from multiple directions, thereby significantly improving the damping effect and stability of the optoelectronic pod 24. The damping holes 26 not only serve to mount the damping elements 20, but their hollow structure also helps reduce the weight of the damper mounting plate 21 and generates a certain air damping effect, thus providing auxiliary damping.

[0028] In one alternative, the star-shaped connecting plate 7 is provided with at least one adjusting slot for mounting the tension wheel shaft 11. The tension wheel shaft 11 is fixedly mounted in the adjusting slot by a locking nut. A tension wheel 10 is coaxially rotatably connected to the tension wheel shaft 11, and the outer edge of the tension wheel 10 abuts against the belt 14. The tension wheel shaft 11 is locked in different positions of the adjusting slot by tightening the lock nut, so as to adjust the tension of the tension wheel 10 on the belt 14.

[0029] By adjusting and locking the position of the tension wheel shaft 11 in the adjustment slot of the star-shaped connecting plate 7, the pressure of the tension wheel 10 on the belt 14 can be changed, making it convenient to adjust the tension of the belt 14. This effectively prevents slippage or loosening during transmission, ensuring the stability and reliability of the transmission system during long-term use, thereby ensuring the reliability and efficiency of the motor 13 in transmitting power to the driven wheel 9.

[0030] In one alternative embodiment, the gimbal outer frame 100 includes an outer frame 1, and a star-shaped connecting plate 7 is fixedly installed inside the outer frame 1.

[0031] The outer frame 1 is made of carbon fiber, and the outer frame 1 has a triangular hollow structure.

[0032] The star-shaped connecting plate 7 is fixedly installed inside the outer frame 1, forming a rigid support base for the entire transmission lifting mechanism 200. This ensures the stability of the relative positions of each component during transmission, and allows the forces from the drive assembly and lifting assembly 400 to be reliably transmitted through the star-shaped connecting plate 7 and distributed to the robust outer frame 1.

[0033] In one alternative, the outer frame 1 is also equipped with a control module 4, a limit switch 6, and an electric speed controller 3. The control module 4 is connected to the electric speed controller 3 by signal, and the electric speed controller 3 is connected to the motor 13 by electrical connection. The limit switch 6 is configured to detect the position of the shock absorber mounting plate 21 and is connected to the control module 4 by signal.

[0034] The control module 4 sends signals to the electronic speed controller 3 according to the instructions, and the electronic speed controller 3 precisely controls the operation of the motor 13. At the same time, the limit switch 6 detects the position of the shock absorber fixing plate 21 in real time and feeds it back to the control module 4, thus forming a closed-loop control system to realize automatic control and precise limit of the gimbal lifting stroke, improving the automation level and safety of operation.

[0035] In one alternative, the outer frame 1 is also equipped with a lidar 5 and an edge computing card 2. The lidar 5 is located at the bottom of one side of the outer frame 1, and the edge computing card 2 is connected to the control module 4 for signal processing of the lidar 5.

[0036] The LiDAR 5, mounted at the bottom of the external frame 1, collects environmental data in real time, which is then processed locally and rapidly by the edge computing card 2. The processed information is sent to the control module 4, providing data support for intelligent decision-making such as obstacle avoidance and path planning for the UAV, thereby enhancing the environmental awareness and autonomous operation capabilities of the gimbal and UAV system.

[0037] In one alternative, a baffle plate 22 is fixedly connected to one side of the shock absorber mounting plate 21, and the baffle plate 22 is configured to correspond to the limit switch 6.

[0038] The baffle 22, which moves up and down with the shock absorber mounting plate 21, triggers the limit switch 6 when it moves to the preset position, converting the mechanical position of the shock absorber mounting plate 21 into an electrical signal, providing direct and reliable position feedback to the control module 4.

[0039] In one alternative, the damping element 20 is a sphere made of an elastic material.

[0040] The shock-absorbing element 20 is made of an elastic material and its spherical structure gives it isotropic elastic properties. Regardless of the direction of vibration, the shock-absorbing element 20 can deform accordingly to absorb kinetic energy, thereby providing excellent all-round buffering effect for the optoelectronic pod 24.

[0041] When the drone enters take-off, landing, or high-speed cruise mode and needs to retract the gimbal, the control module 4 issues a command, and the ESC 3 starts and drives the motor 13 to run. The output shaft of the motor 13 drives the drive wheel 8, which is fixed to it on the same axis, to rotate. The power is transmitted through the belt 14. The belt 14 meshes and transmits power in the transmission circuit consisting of the drive wheel 8, multiple driven wheels 9 arranged at equal intervals in the circumference, and the tension wheel 10. The tension wheel 10 is mounted on the star-shaped connecting plate 7 through the tension wheel shaft 11, and its tension on the belt 14 can be adjusted by adjusting the slot and locking nut to prevent slippage. The rotation of the driven wheel 9 drives the corresponding lead screw 16, which is coaxially fixed to it, to rotate. Each lead screw 16 is supported by bearings 12 at both ends on bearing seats 25 fixed to one side of the guide rail 19, thereby converting the rotational motion into the precise linear motion of the nut 17 threadedly engaged with the lead screw 16. The nut 17 is fixedly connected to the slider 18 through a U-shaped block 15, and the slider 18 is constrained to slide on the guide rail 19 fixed to the outer frame 1 of the gimbal outer frame 100. Therefore, the linear motion of the nut 17 drives the slider 18, the U-shaped block 15, and the nut 17 to rotate. The shock absorber mounting plate 21 rises smoothly along the guide rail 19. This rise, in turn, causes the pod base 23 and the optoelectronic pod 24, connected to the shock absorber element 20, to be retracted into the gimbal outer frame 100. During this process, the baffle 22 fixed to one side of the shock absorber mounting plate 21 moves upward. When it reaches the preset position, it triggers the limit switch 6 installed on the outer frame 1. The limit switch 6 sends a signal back to the control module 4, and the system determines that the gimbal is in position and commands the motor 13 to stop. During UAV flight and gimbal operation... During this process, the multi-directional vibrations generated by the aircraft are transmitted to the star-shaped connecting plate 7 via the structure. The vibrations are then buffered and absorbed by the spherical damping elements 20 made of elastic material installed in the damping holes 26 that are equally spaced around the periphery of the damper fixing plate 21. At the same time, the lidar 5 installed on the external frame 1 continuously collects environmental data, which is processed in real time by the edge computing card 2 located nearby, and the results are sent to the control module 4 to provide decision support for the intelligent operation of the UAV. Ultimately, this achieves a comprehensive technical effect of smooth gimbal lifting, efficient vibration reduction, intelligent control, and lightweight structure.

[0042] In summary, this invention achieves multi-point synchronous drive and ensures the smoothness of lifting by coordinating the design of the star-shaped connecting plate 7 and the circumferentially arranged transmission lifting mechanism 200; it achieves efficient multi-directional vibration reduction by placing the shock-absorbing element 20 between the shock absorber fixing plate 21 and the pod base 23 and combining it with the shock-absorbing hole 26; it ensures the long-term reliability of power transmission through the adjustable belt tensioning structure 14; and it combines the lightweight gimbal outer frame 100 and the integrated intelligent control system to form a compact, reliable, and suitable UAV lifting gimbal device for harsh flight environments, effectively overcoming the shortcomings of traditional gimbals such as poor vibration reduction, bulky structure, and unstable transmission.
