[0004] However, during the use process, since the unmanned aerial vehicle will swing during flight, causing the rangefinder to swing along with the unmanned aerial vehicle, a gimbal is usually selected for stable adjustment. However, the gimbal is greatly affected by wind during use, affecting the use of the rangefinder, and the production and use costs are relatively high. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantages in the prior art that a gimbal is used for stable adjustment, but the gimbal is greatly affected by wind during use, affecting the use of the rangefinder, and the production and use costs are relatively high, and to propose a ranging device carried by an unmanned aerial vehicle.

[0006] To achieve the above purpose, the present invention adopts the following technical solution:

[0007] A ranging device carried by an unmanned aerial vehicle, comprising: a frame and four rotary wings arranged on the sides of the frame.

The side magnetic ring is fixedly connected inside the side offset groove. The lower pushing ring is fixedly connected inside the bottom slot opening of the installation groove, and the magnetic pole of the side close to the side magnetic ring is the same as that of the side magnetic ring.

[0014] Preferably, the energization adjustment component includes a control ring, an upper energized solenoid, a lower energized solenoid and a bottom ring. The control ring is fixedly installed in the middle of the installation groove. The upper energized solenoid is fixedly connected to the upper side of the control ring and is fixedly connected to the iron core ring. The lower energized solenoid is fixedly installed at the bottom end of the control ring. The bottom ring is fixedly connected to the bottom end of the lower energized solenoid.

[0015] Preferably, an air guide groove is arranged on the upper side of the installation column. A wind force detection component is arranged in the middle of the air guide groove. The wind force detection component is used to detect the wind force at the position of the distance measuring component.

[0016] Preferably, the wind force detection component includes a driving detection ring, a plurality of rotating shafts and a plurality of blades. The driving detection ring is rotatably arranged in the middle of the installation column. A plurality of rotating openings are arranged on the side of the driving detection ring. The plurality of rotating shafts are respectively rotatably installed inside the rotating openings. The plurality of blades are respectively fixedly connected to the sides of the plurality of rotating shafts.

[0017] Preferably, a downward pressure assembly is provided between the rotating shaft and the core ring, and the downward pressure assembly includes a plurality of pressure blocks and a pressure ring. The plurality of pressure blocks are respectively fixedly connected to the sides of the rotating shaft, and the pressure ring is rotatably connected to the sides of the core ring, and is made of graphite material and is used to move the pressure blocks downward.

[0018] Preferably, a sliding groove is provided at the bottom end of the mounting column, a sliding cover is provided inside the sliding groove, the sliding cover is slidably arranged inside the sliding groove, and a plurality of air guide ports are annularly arranged at the bottom of the sliding cover, two sliding openings are symmetrically opened on the side of the mounting column, the side of the sliding cover is fixedly connected to the side of the bottom ring through a connecting strip, and the connecting strip is slidably arranged inside the sliding opening.

The multiple cleaning strips are fixedly connected to the inner side of the protective sheet and are in contact with the spherical outer shell.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. When the power-on adjustment component is not powered on, the upper magnetic ring fixed on the limit ball is pushed by the upper push ring to suspend and limit the position of the limit ball. When wind force and swing are generated, the power-on adjustment component is powered on to generate a magnetic field on the core ring, thereby strengthening the repulsive force between the limit ball and the limit ball. Since the center of gravity position of the distance measuring component remains unchanged and there is a swinging gap between the distance measuring component and the mounting groove, it is ensured that when the frame swings, the distance measuring component can be guaranteed not to swing. The present invention can ensure the normal use of the distance measurement while reducing the influence of external factors on the distance measuring device, and at the same time optimizes the balance structure to ensure the distance measurement effect;

[0022] 2. Since the entire distance measuring component will be affected by wind during the distance measuring process, dust is likely to adhere to the distance measuring camera, and it is also likely to cause the distance measuring camera to swing. By setting a transparent spherical shell for protection on the outside of the distance measuring camera, the wind force received can be deflected to both sides while ensuring the normal operation of the distance measuring camera, thereby reducing the impact of wind on the distance measuring camera;

[0023] 3. There is a repulsive force between the side magnetic ring and the lower push ring, which plays a role in radial adjustment of the connecting rod. When the connecting rod swings radially, the adjustment is pushed by this contactless repulsive force, so as to ensure that the position of the connecting rod will not deviate greatly when subjected to force, thereby ensuring the distance measurement effect;

[0024] 4. According to the usage requirements, the current flowing into the upper and lower energized solenoids can be controlled, so as to change the magnitude of the generated magnetic field under different wind force conditions, ensuring stable support for the ranging component;

[0025] 5. When the ranging component is not in use, the sliding cover will block the entire air guide groove, thereby protecting the internal wind force detection component. When ranging is required, the energization of the lower energized solenoid will drive the bottom ring to move upward, thereby driving the entire sliding cover to move upward, transferring the air guide opening to the position of the air guide groove, ensuring that the wind force acts on the blades, changing the blockage according to the change of the working state, reducing the internal working components, and ensuring the use effect;

[0026] 6. Since dust will adhere to the spherical shell during use, affecting the normal use of the ranging camera, during the upward movement of the protective sheet, multiple cleaning strips arranged inside the protective sheet will clean the surface of the spherical shell, thereby ensuring the cleanliness of the spherical shell and not affecting the normal ranging of the ranging camera.

Detailed implementation manners

[0038] 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 the embodiments.

[0039] Terms such as "upper", "lower", "left", "right", "middle", and "one" cited in the present invention are only for the convenience of clear narration, rather than to limit the scope of implementation of the present invention. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope of implementation of the present invention.

[0040] Refer to Figures 1-10 , a ranging device carried by a drone, including: a frame 1 and four rotary wings 2 arranged on the side of the frame 1. An installation opening is provided at the bottom of the frame 1, and a mounting assembly 3 is arranged inside the installation opening. The mounting assembly 3 includes a mounting post 31;

[0041] The mounting post 31 is arranged inside the installation opening, and an installation groove is provided at the bottom. A ranging assembly 4 is arranged inside the installation groove. The ranging assembly 4 includes a limiting ball 41. The top of the installation groove is spherical, and the limiting ball 41 is arranged inside the top of the installation groove;

[0042] A limiting component 5 is arranged inside the installation groove. The limiting component 5 includes a plurality of upper magnetic rings 51, an upper pushing ring 52 and an iron core ring 53. A plurality of the upper magnetic rings 51 are fixedly connected to the limiting ball 41. The upper pushing ring 52 is fixedly connected inside the iron core ring 53. One side of the upper magnetic ring 51 close to the upper pushing ring 52 has the same magnetism, which is used for magnetically supporting the limiting ball 41.

[0043] An energization adjustment component 6 is arranged below the iron core ring 53. The energization adjustment component 6 is used to generate a magnetic field on the iron core ring 53 and directly generate a repulsive force with the magnetic ring.

[0044] In the embodiment applying the above technical solution, since the ranging component 4 is easily interfered by the swing of the frame 1 and wind during use, affecting the stability of the ranging component 4, it is necessary to ensure that the position of the ranging component 4 does not shift during the flight of the drone.

[0045] When the energization adjustment component 6 is not energized, the upper magnetic ring 51 fixed on the limiting ball 41 is repulsively pushed by the upper pushing ring 52 to suspend and limit the position of the limiting ball 41. When wind force and swing occur, the energization adjustment component 6 is energized to generate a magnetic field on the iron core ring 53, thereby strengthening the repulsive force with the limiting ball 41. Since the center of gravity position of the ranging component 4 remains unchanged and there is a swinging gap between the ranging component 4 and the installation groove, it is ensured that when the frame 1 swings, the ranging component 4 can be ensured not to swing.

[0046] The present invention can ensure the normal use of ranging while reducing the influence of external factors on the ranging device, and at the same time optimizing the balance structure to ensure the ranging effect.

[0047] The preferred technical solution in this embodiment:

[0048] Refer to Figures 1-2 , the installation component 3 further includes a connecting wire 33 and a control module 32. The control module 32 is arranged inside the fuselage. The installation column 31 is vertically and fixedly installed at the bottom end of the control module 32. The connecting wire 33 is arranged inside the installation groove and is fixedly connected to the limiting ball 41 at the bottom end.

[0049] When not working, the entire ranging component 4 is assisted and pulled for support through the connecting wire 33, and the lower upper pushing ring 52 also supports the limiting ball 41. When working, the entire ranging component 4 is magnetically supported by the limiting component 5. And when the upper pushing ring 52 magnetically pushes the upper magnetic ring 51, since the length of the connecting wire 33 is greater than the distance between the top of the installation groove and the limiting ball 41, it is ensured that the center of gravity of the entire ranging component 4 will not be affected by the upper pulling. An outer layer with high toughness and high wear resistance is arranged on the outer side of the connecting wire 33 to ensure the service life of the connecting wire 33.

[0050] The control module 32 is used to receive signals inside the entire invention, so as to make corresponding controls to ensure the stability of the entire ranging component 4.

[0051] Refer to Figures 1-4 , the ranging component 4 further includes a connecting rod 42, a ranging camera 43 and a spherical housing 44. The connecting rod 42 is fixedly connected below the limiting ball 41. The spherical housing 44 is fixedly installed at the bottom end of the connecting rod 42. The ranging camera 43 is rotatably installed inside the spherical housing 44 for ranging. The spherical housing 44 is made of a transparent material and is provided with a weight at the bottom end.

[0052] Since the entire ranging component 4 will be affected by wind force during the ranging process, it is easy for dust to adhere to the ranging camera 43, and at the same time, it is easy for the ranging camera 43 to swing. By setting a transparent spherical housing 44 for protection outside the ranging camera 43, while ensuring the normal operation of the ranging camera 43, the wind force received can be deflected to both sides, reducing the influence of the wind force on the ranging camera 43.

[0053] Refer to Figure 3 , the limiting component 5 further includes a side magnetic ring 54 and a lower pushing ring 55. An offset ring groove is provided in the middle of the connecting rod 42. The side magnetic ring 54 is fixedly connected inside the side offset groove. The lower pushing ring 55 is fixedly connected inside the bottom slot of the installation slot, and the magnetic pole on the side close to the side magnetic ring 54 is the same as that of the side magnetic ring 54.

[0054] There is a repulsive force between the side magnetic ring 54 and the lower pushing ring 55, thus playing a role in radially adjusting the connecting rod 42. When the connecting rod 42 swings radially, through this non-contact repulsive force push adjustment, it is ensured that when stressed, the position of the connecting rod 42 will not deviate greatly, ensuring the ranging effect.

[0055] Refer to Figure 4 , the energization adjustment component 6 includes a control ring 61, an upper energized solenoid 62, a lower energized solenoid 63 and a bottom ring 64. The control ring 61 is fixedly installed in the middle of the installation slot. The upper energized solenoid 62 is fixedly connected to the upper side of the control ring 61 and is fixedly connected to the iron core ring 53. The lower energized solenoid 63 is fixedly installed at the bottom end of the control ring 61. The bottom ring 64 is fixedly connected to the bottom end of the lower energized solenoid 63.

[0056] There are two power supplies inside the control ring 61, which are respectively used to control the upper energized solenoid 62 and the lower energized solenoid 63. When the surveying and mapping component is working, first the lower energized solenoid 63 is energized, and then the upper energized solenoid is energized. After the upper energized solenoid 62 is energized, a magnetic field with the same magnetism as the upper magnetic ring 51 will be generated on the side of the iron core ring 53 close to the upper magnetic ring 51, which will strengthen the repulsive force between the upper magnetic ring 51 and the iron core ring 53, so as to ensure the magnetic suspension support for the ranging component 4.

[0057] At the same time, according to the usage requirements, the current flowing into the upper energized solenoid 62 and the lower energized solenoid 63 can be controlled, so as to change the magnitude of the generated magnetic field under different wind force conditions and ensure the stable support for the ranging component 4.

[0058] After the bottom ring 64 is energized to generate a magnetic field, it will also generate a repulsive force with the magnetic field generated by the side magnetic ring 54, magnetically limit the middle part of the connecting rod 42, and reduce the shaking of the ranging component 4 caused by the wind force and the swing of the frame 1 through the magnetic suspension in the radial and axial directions at the upper and lower ends.

[0059] Refer to Figures 4-5 As shown in the figure, a wind guide groove is opened on the upper side of the mounting column 31, and a wind force detection component 7 is arranged in the middle of the wind guide groove. The wind force detection component 7 is used to detect the wind force at the position of the ranging component 4;

[0060] The wind force detection component 7 includes a driving detection ring 71, a plurality of rotating shafts 72 and a plurality of blades 73. The driving detection ring 71 is rotatably arranged in the middle of the mounting column 31. A plurality of rotating openings are opened on the side of the driving detection ring 71. A plurality of the rotating shafts 72 are respectively rotatably installed in the rotating openings, and a plurality of the blades 73 are respectively fixedly connected to the sides of the plurality of rotating shafts 72.

[0061] Since the wind force acting on the ranging component 4 is different in different wind force environments, in order to ensure the precise regulation of the energized regulation component and avoid waste of electricity, the wind force detection component 7 can be set to accurately detect the intensity of the wind force.

[0062] When not in use, the fan blades are vertically arranged and clamped in the wind guide groove to avoid affecting the transfer and carrying of the drone. When in use, the blades 73 are horizontally unfolded. The driving detection ring 71 drives the blades 73 to rotate. The magnitude of the wind force is detected by the rotation speed of the blades 73. The detection of the wind force is transmitted to the control module 32 through the transmitter inside the driving detection ring 71, and then the control module 32 emits a signal to the inside of the control ring 61 to accurately control the magnitude of the magnetic field.

[0063] Refer to Figure 5, a pressing component 8 is arranged between the rotating shaft 72 and the iron core ring 53. The pressing component 8 includes a plurality of pressing blocks 81 and a pressing ring 82. The plurality of pressing blocks 81 are respectively fixedly connected to the side of the rotating shaft 72. The pressing ring 82 is rotatably connected to the side of the iron core ring 53 and is made of graphite material for pressing down the pressing blocks 81.

[0064] When the distance measuring component 4 is working, since the upper energized solenoid 62 will expand and contract after being energized, the upper energized solenoid 62 will drive the iron core ring 53 to move downward, thereby driving the pressing ring 82 fixed below the iron core ring 53 to move downward. The downward moving pressing ring 82 will drive the pressing blocks 81 to deflect downward, and the blade 73 connected to the rotating shaft 72 on the other side will deflect upward, keeping the blade 73 horizontal, increasing the wind force receiving surface of the blade 73, and ensuring the rotation of the blade 73.

[0065] Only when the distance measuring camera 43 is working, the blade 73 will be unfolded. When not working, the blade 73 can be retracted, reducing the floor area of the entire drone, avoiding damage to the blade 73 at the same time, and ensuring the normal use of the blade 73.

[0066] Refer to Figures 6-7 , a sliding groove is arranged at the bottom end of the mounting post 31. A sliding cover 10 is arranged inside the sliding groove. The sliding cover 10 is slidably arranged inside the sliding groove, and a plurality of air guide openings are annularly arranged at the bottom of the sliding cover 10.

[0067] When the distance measuring component 4 is not in use, the sliding cover 10 will block the entire air guide groove, thereby protecting the internal wind force detecting component 7. When distance measurement is required, the lower energized solenoid 63 is energized to drive the bottom ring 64 to move upward, thereby driving the entire sliding cover 10 to move upward, transferring the air guide openings to the position of the air guide groove, ensuring that the wind force acts on the blade 73, changing the block according to the change of the working state, reducing the internal working components, and ensuring the use effect.

[0068] Refer to Figure 8 , a protection component 9 is arranged at the bottom of the sliding cover 10. The protection component 9 includes a plurality of elastic shafts 91, a plurality of protection pieces 92 and a plurality of cleaning strips 93. The plurality of elastic shafts 91 are annularly and fixedly connected to the bottom of the sliding cover 10. The plurality of protection pieces 92 are respectively fixedly connected below the plurality of elastic shafts 91 to form a spherical cover. The plurality of cleaning strips 93 are fixedly connected to the inner side of the protection pieces 92 and are in contact with the spherical outer shell 44.

[0069] After the lower energized solenoid 63 is energized to drive the bottom ring 64 to move upward, the protection component 9 installed on the bottom ring 64 moves upward. The protection pieces 92 will move upward along the outer side of the spherical outer shell 44, exposing the internal spherical outer shell 44, so as to facilitate the distance measurement work of the distance measuring camera 43 and protect the distance measuring camera 43 usually.

[0070] Since the spherical housing 44 will adhere to dust during use, affecting the normal use of the ranging camera 43, during the upward movement of the protective sheet 92, a plurality of cleaning strips 93 provided inside the protective sheet 92 will clean the surface of the spherical housing 44, thereby ensuring the cleanliness of the spherical housing 44 and not affecting the normal ranging of the ranging camera 43.

[0071] 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 substitutions or changes, and should be covered within the protection scope of the present invention.
