Description

Technical Field

[0001] The present invention relates to the technical field of aircraft, and in particular to a wireless controller for an aerial photography aircraft. Background Art

[0002] An aerial photography aircraft is an unmanned aircraft controlled by a radio remote control device and a self - contained program control device. It is mainly used in fields such as aerial photography and videography. It can obtain unique perspectives and images from the air. A wireless controller is a device used to remotely control the flight of an aerial photography aircraft. It communicates with the aircraft through wireless signals, enabling the operator to conveniently control the flight attitude, flight path of the aircraft, and related functions of the shooting device on the ground.

[0003] After retrieval, the remote controller of an unmanned aircraft of Chinese patent with the publication number CN110972502A includes a main body and a holding device. The holding device is movably connected to the main body. The holding device can be in a retracted state relative to the main body, and the holding device can be in an extended state relative to the main body for clamping a terminal. An avoidance hole is provided on the holding device. The avoidance hole is used to expose the operation keys of the terminal when the holding device clamps the terminal. The holding device can be in an extended state relative to the main body to clamp the terminal, so that the terminal is stably connected to the remote controller. An avoidance hole is provided on the holding device. When the holding device clamps the terminal, the operation keys of the terminal are exposed from the avoidance hole. Therefore, the user can operate the operation keys of the terminal without removing the terminal from the remote controller, which greatly facilitates the user to operate the terminal when the terminal is clamped. However, when the above - mentioned technical solution is implemented, there are still the following deficiencies: Most of the current mainstream wireless controllers adopt an integrated fixed joystick design, with a constant length, fulcrum, and movement trajectory. As a result, the pushing distance and output angle of the joystick show a fixed transmission ratio. However, there are differences among operators in physiological characteristics, operating habits, and flight experience. The fixed transmission ratio is difficult to adapt to diverse requirements. Operators with small hands may have difficulty in precise control due to the long joystick travel, while users accustomed to large - scale operations will be restricted by the short travel. The fixed - type design violates the principles of ergonomics, not only reducing the operation efficiency, increasing the risk of misoperation, but also affecting flight safety and the performance of the device, and unable to meet the differentiated requirements of professional operations for control sensitivity and accuracy. Therefore, it is necessary to design a wireless controller for an aerial photography aircraft to solve the above problems. Summary of the Invention

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Referring to Figures 1 to 10 as shown, a wireless controller for an aerial photography aircraft includes a remote control unit and an adjustment unit; The remote control unit includes a housing 11. A display screen 12 is embedded in the upper surface of the housing 11. A folding antenna 13 is provided on the side of the housing 11. A seat groove 14 is formed on the upper surface of the housing 11. A pivot joint 15 is arranged inside the seat groove 14. When using this wireless controller to remotely control the aircraft, the folding antenna 13 is unfolded to optimize the signal transmission performance by its mechanical structure.

[0020] As Figures 2 to 7 As shown, the adjusting unit includes an outer cylinder 21 fixedly connected to the top end of the pivot joint 15. A rocker 22 is slidably connected inside the outer cylinder 21. An inner rod 23 is rotatably connected inside the rocker 22. A positioning component is arranged on the outer surface of the outer cylinder 21. The bottom end of the inner rod 23 is fixedly connected with a turntable 24. An arc groove 25 is formed through the outer surface of the turntable 24. A clamping block 26 is movably inserted through the outer surface of the rocker 22. The clamping block 26 is movably connected inside the arc groove 25. A clamping groove 27 is formed on the inner wall of the outer cylinder 21. The position of the clamping groove 27 corresponds to that of the clamping block 26, and each clamping groove 27 is linearly and evenly distributed along the inner wall of the outer cylinder 21. The clamping block 26 is clamped inside the clamping groove 27. A torsion spring 28 is sleeved on the outer surface of the inner rod 23. One end of the torsion spring 28 away from the inner rod 23 is fixedly connected to the inner wall of the rocker 22; Rotating the inner rod 23 drives the turntable 24 to rotate. During this process, the torsion spring 28 is compressed to store elastic potential energy. The clamping block 26 arranged on the outer periphery of the turntable 24 slides radially along the arc groove 25 and disengages from the clamping groove 27 fixed on the outer cylinder 21 of the rocker 22. At this time, the rocker 22 can be lifted upward, and linear sliding is achieved by the guiding cooperation between the inner rod 23 and the inner wall of the outer cylinder 21 to complete the height adjustment. After releasing the inner rod 23, the elastic potential energy stored in the torsion spring 28 is converted into a rotational driving force, driving the inner rod 23 to rotate back to its original position, and then pushing the clamping block 26 to radially extend from inside the rocker 22 along the arc groove 25 and snap into the corresponding clamping groove 27, realizing the locking of the rocker 22, achieving the purpose of adjusting the height of the rocker 22, enabling the operator to optimize the operation stroke according to their own operation habits, and improving the operation sensitivity and control accuracy.

[0021] As Figures 2 to 4 As shown, the positioning component includes a positioning ring 31 fixedly sleeved on the outer surface of the rocker 22. An upper pull rod 32 is hinged on the outer surface of the positioning ring 31. A lower pull rod 33 is hinged on the outer surface of the outer cylinder 21. A connecting rod 34 is hinged at the connection of the upper pull rod 32 and the lower pull rod 33. A top block 35 is fixedly connected to the outer surface of the connecting rod 34. Grooves 36 are annularly and arrayed on the outer surface edge of the seat groove 14. The top block 35 is clamped inside the grooves 36; When the rocker 22 rises, the upper pull rod 32 and the lower pull rod 33 will contract correspondingly. By pulling the connecting rod 34, the top block 35 is moved out of the groove 36. The upper pull rod 32 and the lower pull rod 33 distributed in an annular array can improve the stability and movement intensity of the rocker 22. Similarly, when the rocker 22 is lowered to the lowest position, the top block 35 will be clamped in the groove 36, playing an effect of locking the rocker 22 and effectively preventing abnormal operations caused by accidental touch after the aircraft lands.

[0022] As Figure 2 , Figure 8 , Figure 9 and Figure 10 shown, the protection unit includes a light-shielding component arranged on the outer surface of the display screen 12, a cleaning component arranged on the upper surface of the housing 11, and a docking component arranged on the outer surface of the folding antenna 13; The light-shielding component includes a support 41 fixedly connected to the rear side of the housing 11. The top end of the support 41 is rotatably connected to a connecting seat 42. The front end of the connecting seat 42 is fixedly connected to a light-shielding plate 43. The end of the light-shielding plate 43 is fixedly connected to an extension plate 44. The outer surface of the extension plate 44 is provided with a side plate 45. The outer surface of the side plate 45 is fixedly connected to a track 47. A side shaft 46 is arranged on the side of the extension plate 44. The track 47 is movably sleeved on the outer surface of the side shaft 46. A strip-shaped groove 48 is formed on the outer surface of the extension plate 44. A support plate 49 is limited and slid in the strip-shaped groove 48. One end of the support plate 49 away from the strip-shaped groove 48 is hinged to the outer surface of the side plate 45; Push the light-shielding plate 43 upward to rotate around the support 41, so that the light-shielding plate 43 and the extension plate 44 form an initial light-shielding plane, effectively blocking direct light. Then, the side plate 45 can be pushed to slide along the outer surface of the extension plate 44. The track 47 will slide along the side shaft 46 and cooperate with the sliding of the support plate 49 in the strip-shaped groove 48 to ensure the smooth movement of the side plate 45. When the side plate 45 slides to the target position, it rotates around the side shaft 46. The side plate 45 and the extension plate 44 form a trapezoidal light-shielding structure, significantly expanding the light-shielding range and reducing the reflection interference of environmental strong light on the display screen 12, thereby improving the visual comfort and operation accuracy of users in outdoor environments.

[0023] As Figure 3 and Figure 8 shown, the cleaning component includes an inclined pull rod 51 hinged to the outer surface of the light-shielding plate 43. One end of the inclined pull rod 51 away from the light-shielding plate 43 is hinged to a slider 53. Two chutes 54 are formed on the upper surface of the housing 11 and are symmetrically distributed on both sides of the display screen 12. The slider 53 is limited and slid in the chute 54. The opposite sides of the slider 53 are rotatably connected to a cleaning roller 52. The cleaning roller 52 covers the outer surface of the display screen 12; During the deployment and retraction of the light shield 43, under the action of the diagonal tie rod 51, the slider 53 is pulled to slide inside the chute 54, which in turn drives the cleaning roller 52 to move. During the movement of the cleaning roller 52, the display screen 12 is cleaned, achieving the effect of cleaning the dust attached to the surface of the display screen 12 and ensuring the clarity of the display image.

[0024] As Figure 2 , Figure 3 and Figure 10 shown, the docking assembly includes a collar 61 movably sleeved on the outer surface of the folding antenna 13. A docking rod 62 is movably inserted through the inside of the collar 61. A ring 63 is movably sleeved on the outer surface of the collar 61. The ring 63 is fixedly connected to the docking rod 62. A docking plate 64 is fixedly sleeved at the end of the folding antenna 13. Docking holes 65 are annularly arrayed on the outer surface of the docking plate 64. The docking rods 62 inside the collars 61 on the outer surfaces of the two folding antennas 13 are staggeredly distributed, ensuring that they can be staggeredly snapped into the docking holes 65 during docking. A locking ring 66 is fixedly sleeved at the tail end of the folding antenna 13. Locking holes 67 are annularly arrayed on the outer surface of the locking ring 66; When the folding antenna 13 is deployed, the collar 61 is pushed towards the locking ring 66 until the collar 61 covers the bent part of the folding antenna 13. The ring 63 is pushed to insert the docking rod 62 into the locking hole 67, achieving the effect of protecting the bent part of the folding antenna 13 and ensuring the stability of the folding antenna 13 after deployment. When the folding antenna 13 is retracted, the collar 61 is pushed towards the docking plate 64. After they are fitted together, the ring 63 is pushed to make the docking rod 62 penetrate through the docking plate 64 and insert into the opposite docking hole 65, so that the two folding antennas 13 are docked and placed under the connecting seat 42, realizing the firm fixation of the antenna through mechanical plugging, achieving the compact storage of the antenna, and restricting the flipping of the connecting seat 42 through the mechanical limiting principle to ensure that the light shielding component always maintains effective protection for the display screen 12.

[0025] When using the wireless controller to remotely control the aircraft, the technical solution provided by the present invention first unfolds the folding antenna 13, optimizes the signal transmission performance by using its mechanical structure, and pushes the collar 61 towards the locking ring 66 until the collar 61 covers the bent part of the folding antenna 13. Then, the circular ring 63 is pushed so that the docking rod 62 is inserted into the locking hole 67, which has the effect of protecting the bent part of the folding antenna 13 and ensuring the stability of the folding antenna 13 after unfolding. Then, the light-shielding plate 43 is pushed upward to rotate around the support 41 and stopped at a suitable position, so that the light-shielding plate 43 and the extension plate 44 form an initial light-shielding plane, effectively blocking direct light. Then, the side plate 45 can be pushed to slide along the outer surface of the extension plate 44. The track 47 will slide along the side axis 46 to cooperate with the sliding of the support plate 49 in the strip-shaped groove 48 to ensure the stable movement of the side plate 45. When the side plate 45 slides to the target position, it rotates around the side axis 46. During this process, the support plate 49 deflects through the lever principle, and the mechanical stop structure is used to support and limit the side plate 45. The side plate 45 and the extension plate 44 form a trapezoidal light-shielding structure, significantly expanding the light-shielding range and reducing the reflection interference of environmental strong light on the display screen 12, thereby improving the visual comfort and operation accuracy of the user in the outdoor environment. And during the unfolding process of the light-shielding plate 43, under the action of the inclined pull rod 51, the slider 53 is pulled to slide inside the chute 54, and then the cleaning roller 52 is driven to move. During the movement of the cleaning roller 52, the display screen 12 is cleaned, which has the effect of cleaning the dust attached to the surface of the display screen 12; Before starting to operate the device after the light shield 43 is unfolded, the height of the joystick 22 can be adjusted according to personal needs. First, rotate the inner rod 23 to drive the turntable 24 to rotate. During this process, the torsion spring 28 is compressed to store elastic potential energy. The clamping block 26 arranged on the outer circumference of the turntable 24 slides radially along the arc-shaped groove 25 and disengages from the clamping groove 27 fixed on the outer cylinder 21 of the joystick 22, releasing the locking state of the joystick 22. At this time, the joystick 22 can be lifted upward, and linear sliding is achieved by the guiding cooperation between the inner rod 23 and the inner wall of the outer cylinder 21 to complete the height adjustment. When the joystick 22 rises to a height suitable for the operator to operate, release the inner rod 23. The elastic potential energy stored in the torsion spring 28 is converted into a rotational driving force, driving the inner rod 23 to rotate back to its original position, and then pushing the clamping block 26 to radially extend from the inside of the joystick 22 along the arc-shaped groove 25. If the clamping block 26 is not completely aligned with the clamping groove 27 of the outer cylinder 21, the operator slightly moves the joystick 22 up and down, and uses the inclined plane guiding structure of the clamping block 26 to automatically fall into the corresponding clamping groove 27 during the sliding process, realizing the locking of the joystick 22, achieving the purpose of adjusting the height of the joystick 22, enabling the operator to optimize the operation stroke according to personal operation habits, and improving the operation sensitivity and control accuracy. The outer surfaces of the joystick 22 and the outer cylinder 21 are provided with a positioning component. When the joystick 22 rises, the upper pull rod 32 and the lower pull rod 33 will contract correspondingly. By pulling the connecting rod 34, the top block 35 is moved out of the groove 36. The upper pull rod 32 and the lower pull rod 33 distributed in a circular array can improve the stability and movement strength of the joystick 22; After the operation is completed, similarly, operate the joystick 22 to descend to the lowest position. At this time, the top block 35 will be clamped in the groove 36, playing an effect of locking the joystick 22, effectively preventing abnormal operations caused by accidental touches after the aircraft lands. During the process of closing the light shielding component, the cleaning roller 52 also cleans the display screen 12 to remove the dust that has fallen on it during the operation process. The light shield 43 and the extension plate 44 cover the display screen 12 to provide physical protection for the display screen 12. Finally, rotate the folding antenna 13 and push the collar 61 towards the docking plate 64. After the two are fitted, push the circular ring 63 so that the docking rod 62 penetrates the docking plate 64 and inserts into the opposite docking hole 65, making the two folding antennas 13 dock and placed under the connecting seat 42, realizing the stable fixation of the antenna through a mechanical plug-in method. This structure not only realizes the compact storage of the antenna, but also restricts the flipping of the connecting seat 42 through the mechanical limiting principle, ensuring that the light shielding component always maintains effective protection for the display screen 12.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
