[0011] Preferably, an air guide groove is provided on the upper side of the mounting column, a wind force detection component is provided in the middle of the air guide groove, and the wind force detection component is used to detect the wind force at the position of the ranging component.

[0012] Preferably, the wind force detection assembly includes a drive detection ring, multiple rotating shafts and multiple blades. The drive detection ring is rotatably set in the middle of the mounting column. Multiple rotating openings are opened on the side of the drive detection ring.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 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; 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; 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; 4. According to the needs of use, the current passing through the upper and lower powered spiral tubes can be controlled, so as to change the size of the generated magnetic field under different wind strengths to ensure stable support for the ranging component; 5. When the distance measuring component is not in use, the sliding cover will block the entire air guide slot, thereby shielding and protecting the internal wind force detection component. When distance measurement is required, the lower powered spiral tube is energized to drive the bottom ring to move upward, thereby driving the entire sliding cover to move upward, and transferring the air guide port to the position of the air guide slot to ensure that the wind force acts on the blades. The blocking changes according to the change of working status, reducing the internal working components and ensuring the use effect; 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 that the spherical shell is clean and will not affect the normal ranging of the ranging camera.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0021] Reference Figure 1-Figure 10 A distance measuring device carried by a drone comprises: a frame 1 and four rotating wings 2 arranged on the sides of the frame 1, a mounting opening is provided at the bottom of the frame 1, a mounting assembly 3 is arranged inside the mounting opening, and the mounting assembly 3 comprises a mounting column 31; The mounting column 31 is arranged inside the mounting opening, and a mounting groove is opened at the bottom. A distance measuring component 4 is arranged inside the mounting groove. The distance measuring component 4 includes a limiting ball 41. The top of the mounting groove is spherical, and the limiting ball 41 is arranged inside the top of the mounting groove. A limiting assembly 5 is arranged inside the installation groove, and the limiting assembly 5 includes a plurality of upper magnetic rings 51, an upper push ring 52 and an iron core ring 53. The plurality of upper magnetic rings 51 are fixedly connected to the limiting ball 41, and the upper push ring 52 is fixedly connected inside the iron core ring 53. The upper magnetic ring 51 and the upper push ring 52 have the same magnetic properties on one side close to each other, and are used to magnetically support the limiting ball 41. An energized regulating component 6 is disposed below the core ring 53 , and the energized regulating component 6 is used to enable the core ring 53 to generate a magnetic field and directly generate a repulsive force with the magnetic ring.

[0022] In the embodiment of the above technical solution, since the ranging component 4 is easily disturbed by the swing of the frame 1 and the wind during use, which affects 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.

[0023] When the power-on adjustment component 6 is not energized, the upper magnetic ring 51 fixed on the limiting ball 41 is repelled by the upper pushing ring 52, so as to suspend and limit the position of the limiting ball 41. When wind force and swinging are generated, the power-on adjustment component 6 is energized to generate a magnetic field on the core ring 53, thereby strengthening the repulsive force between the limiting ball 41 and 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 mounting groove, it is ensured that when the frame 1 swings, the ranging component 4 can be guaranteed not to swing.

[0024] The present invention can ensure the normal use of distance measurement, reduce the influence of external factors on the distance measurement device, optimize the balance structure and ensure the distance measurement effect.

[0025] The preferred technical solution in this embodiment is: Reference Figure 1-Figure 2 The installation component 3 also includes a connecting wire 33 and a control module 32. The control module 32 is arranged inside the body. The installation column 31 is vertically fixedly installed at the bottom of the control module 32. The connecting wire 33 is arranged inside the installation groove, and the bottom end is fixedly connected to the limiting ball 41.

[0026] When not working, the entire distance measuring assembly 4 is auxiliary pulled and supported by the connecting wire 33, and the upper push ring 52 below also supports the limiting ball 41. When working, the entire distance measuring assembly 4 is magnetically supported by the limiting assembly 5, and when the upper push ring 52 magnetically pushes the upper magnetic ring 51, the connecting wire 33 is longer than the distance between the top of the installation slot and the limiting ball 41, thereby ensuring that the center of gravity of the entire distance measuring assembly 4 will not be affected by the pulling of the upper end, and an outer ring layer with high toughness and high refractory material is set on the outside of the connecting wire 33 to ensure the service life of the connecting wire 33.

[0027] The control module 32 is used to receive signals within the entire invention, thereby making corresponding controls to ensure the stability of the entire distance measuring component 4.

[0028] Reference Figure 1-Figure 4 The ranging assembly 4 also includes a connecting rod 42, a ranging camera 43 and a spherical shell 44. The connecting rod 42 is fixedly connected below the limiting ball 41. The spherical shell 44 is fixedly installed at the bottom end of the connecting rod 42. The ranging camera 43 is rotatably installed inside the spherical shell 44 for ranging. The spherical shell 44 is made of transparent material and a weight is arranged at the bottom.

[0029] Since the entire ranging assembly 4 is affected by wind during the ranging process, dust may easily adhere to the ranging camera 43, and the ranging camera 43 may easily swing. By providing a transparent spherical shell 44 for protection on the outside of the ranging camera 43, the wind force received can be deflected to both sides while ensuring the normal operation of the ranging camera 43, thereby reducing the impact of the wind on the ranging camera 43.

[0030] Reference Figure 3 The limit assembly 5 also includes a side magnetic ring 54 and a lower push 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 push ring 55 is fixedly connected inside the notch at the bottom end of the installation groove, and the magnetic pole on one side close to the side magnetic ring 54 is the same as the side magnetic ring 54.

[0031] There is a repulsive force between the side magnetic ring 54 and the lower push ring 55, which plays a role in radial adjustment of the connecting rod 42. When the connecting rod 42 swings radially, the adjustment is pushed by this contactless repulsive force, thereby ensuring that the position of the connecting rod 42 will not deviate significantly when subjected to force, thereby ensuring the distance measurement effect.

[0032] Reference Figure 4 The power-on adjustment component 6 includes a control ring 61, an upper power-on spiral tube 62, a lower power-on spiral tube 63 and a bottom ring 64. The control ring 61 is fixedly installed in the middle of the installation groove, the upper power-on spiral tube 62 is fixedly connected to the upper side of the control ring 61 and is fixedly connected to the core ring 53, the lower power-on spiral tube 63 is fixedly installed at the bottom end of the control ring 61, and the bottom ring 64 is fixedly connected to the bottom end of the lower power-on spiral tube 63.

[0033] Two power supplies are provided inside the control ring 61, which are respectively used to control the upper powered spiral tube 62 and the lower powered spiral tube 63. When the surveying and mapping component is working, the lower powered spiral tube 63 is powered on first, and then the upper powered spiral tube is powered on. After the upper powered spiral tube 62 is powered on, a magnetic field with the same magnetic properties as the upper magnetic ring 51 will be generated on the side of the core ring 53 close to the upper magnetic ring 51, which will strengthen the repulsive force between the upper magnetic ring 51 and the core ring 53, thereby ensuring the magnetic suspension support for the ranging component 4.

[0034] At the same time, according to the needs of use, the current passing through the upper powered spiral tube 62 and the lower powered spiral tube 63 can be controlled, so as to change the size of the generated magnetic field under different wind speeds to ensure stable support for the ranging component 4.

[0035] After the bottom ring 64 is energized to generate a magnetic field, a repulsive force is generated between the bottom ring 64 and the magnetic field generated by the side magnetic ring 54, thereby magnetically limiting the middle of the connecting rod 42. The radial and axial magnetic suspension at the upper and lower ends reduces the shaking of the ranging component 4 caused by the wind force and the swing of the frame 1.

[0036] Reference Figure 4-Figure 5 The upper side of the mounting column 31 is provided with an air guide groove, and the middle part of the air guide groove is provided with a wind force detection component 7, and the wind force detection component 7 is used to detect the wind force at the position of the distance measuring component 4; The wind force detection component 7 includes a driving detection ring 71, multiple rotating shafts 72 and multiple blades 73. The driving detection ring 71 is rotatably set in the middle of the mounting column 31. Multiple rotating openings are opened on the side of the driving detection ring 71. The multiple rotating shafts 72 are respectively rotatably installed inside the rotating openings, and the multiple blades 73 are respectively fixedly connected to the sides of the multiple rotating shafts 72.

[0037] Since the wind force acting on the distance measuring component 4 is different in different wind environments, in order to ensure accurate control of the power-on control component and avoid waste of electricity, the wind force detection component 7 can be set to accurately detect the strength of the wind force.

[0038] When not in use, the fan blades are arranged vertically and stuck inside the wind guide groove to avoid affecting the transfer and carrying of the drone. When in use, the blades 73 are unfolded horizontally and driven by the detection ring 71 to rotate the blades 73. The size of the wind force is detected by the rotation speed of the blades 73. The wind force detection is transmitted to the control module 32 through the transmitter inside the drive detection ring 71, and then the control module 32 transmits a signal to the control ring 61, thereby accurately controlling the size of the magnetic field.

[0039] Reference Figure 5 A pressing assembly 8 is provided between the rotating shaft 72 and the core ring 53. The pressing assembly 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 sides of the rotating shaft 72. The pressing ring 82 is rotatably connected to the sides of the core ring 53 and is made of graphite material for moving the pressing blocks 81 downward.

[0040] When the ranging component 4 is working, since the upper energized spiral tube 62 will expand and contract after being energized, the upper energized spiral tube 62 will drive the iron core ring 53 to move downward, thereby driving the pressure ring 82 fixed under the iron core ring 53 to move downward, and the downward moving pressure ring 82 will drive the pressure block 81 to deflect downward, and the blade 73 connected to the rotating shaft 72 on the other side will deflect upward, so that the blade 73 remains horizontal, increasing the wind force bearing surface of the blade 73 and ensuring the rotation of the blade 73.

[0041] The blades 73 are unfolded only when the ranging camera 43 is working, and can be folded when not working, thereby reducing the footprint of the entire drone and avoiding damage to the blades 73, thereby ensuring the normal use of the blades 73.

[0042] Reference Figure 6-7 A sliding groove is provided at the bottom end of the mounting column 31, a sliding cover 10 is provided inside the sliding groove, the sliding cover 10 is slidably provided inside the sliding groove, and a plurality of air guide ports are provided in an annular shape at the bottom of the sliding cover 10.

[0043] When the distance measuring component 4 is not in use, the sliding cover 10 will block the entire air guide groove, thereby shielding and protecting the internal wind detection component 7. When distance measurement is required, the lower energized spiral tube 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 port to the position of the air guide groove, ensuring that the wind force acts on the blade 73, and the blocking changes according to the change of working status, reducing the internal working components and ensuring the use effect.

[0044] Reference Figure 8 A protective component 9 is provided at the bottom of the sliding cover 10, and the protective component 9 includes multiple elastic shafts 91, multiple protective sheets 92 and multiple cleaning strips 93. The multiple elastic shafts 91 are fixedly connected to the bottom of the sliding cover 10 in an annular shape, and the multiple protective sheets 92 are respectively fixedly connected under the multiple elastic shafts 91 to form a spherical cover. The multiple cleaning strips 93 are fixedly connected to the inner side of the protective sheet 92 and are in contact with the spherical shell 44.

[0045] When the powered spiral tube 63 is powered on to drive the bottom ring 64 to move upward, the protective assembly 9 installed on the bottom ring 64 moves upward, and the protective sheet 92 moves upward along the outer side of the spherical shell 44 to expose the internal spherical shell 44, thereby facilitating the ranging camera 43 to perform ranging work and protecting the ranging camera 43 at ordinary times.

[0046] Since dust will adhere to the spherical shell 44 during use, affecting the normal use of the ranging camera 43, during the upward movement of the protective sheet 92, multiple cleaning strips 93 arranged inside the protective sheet 92 will clean the surface of the spherical shell 44, thereby ensuring that the spherical shell 44 is clean and will not affect the normal ranging of the ranging camera 43.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
