[0025] The following combines Figures 1 - 21 , and details some embodiments of the present invention. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0026] In a first aspect, the present invention provides a mounting fixing device 2 for mounting instruments on a drone. As Figure 2 shown, it includes a box body 3 and a fixing bracket 4; the box body 3 is connected to the fixing bracket 4 and can be fixedly arranged on the drone under the action of the fixing bracket 4; a positioning structure is provided on the box body 3, and the positioning structure is used to fix the mounted instrument inside the box body 3.

[0027] In this embodiment, the box body 3 is a cuboid, that is, it is composed of a top plate 15, a bottom plate 7, a front plate, a rear plate 5, a left plate, and a right plate.

[0028] Among them, the fixed bracket 4 is arranged outside the box body 3 and located on the top plate 15; the positioning structure is partially located inside the box body 3 and is connected to the left plate or the right plate. When the number of the positioning structures is one, it is arranged on the left plate or the right plate, and the carried instrument is pushed with the left plate or the right plate as the reference to press the instrument, so as to realize the positioning of the instrument inside the box body 3 and ensure the stability of the instrument during the flight of the unmanned aerial vehicle. When the number of the positioning structures is even and they are arranged in pairs, they are respectively arranged on the left plate and the right plate, and both can press the carried instrument towards the middle to ensure the stability of the instrument inside the box body 3.

[0029] In this embodiment, the positioning of the instrument in the box body 3 is realized by pressing the instrument through the positioning structure, so that the positioning of the instrument has a certain universality and can be applied to most instruments.

[0030] In this embodiment, one end of the fixed bracket 4 is connected to the top plate 15, and the other end is connected to the rotor bracket or the fixed frame of the unmanned aerial vehicle, so that it can be matched with different models of unmanned aerial vehicles, improving the adaptability of the carrying and fixing device 2.

[0031] Specifically, in this embodiment, the number of the fixed brackets 4 is multiple, and the multiple fixed brackets 4 are symmetrically arranged to ensure that the balance of the unmanned aerial vehicle is not affected when connecting with the unmanned aerial vehicle.

[0032] In an optional implementation manner, the positioning structure includes a positioning plate 10, a guiding structure, and an adjusting structure 6; the positioning plate 10 is arranged inside the box body 3 through the guiding structure; the adjusting structure 6 connects the box body 3 and the positioning plate 10 and can adjust the position of the positioning plate 10 inside the box body 3.

[0033] In this embodiment, the positioning plate 10 is a rigid plate, which can effectively push the instrument to move. To protect the safety of the instrument, a flexible layer can be arranged on the surface of the positioning plate 10 in contact with the instrument.

[0034] In this embodiment, the carried instrument and the positioning plate 10 can both move along the set direction under the action of the guiding structure, which not only ensures the convenience of movement but also limits the instrument to a certain extent, thus ensuring the stability of the instrument when installed inside the box body 3.

[0035] In this embodiment, taking the adjusting structure 6 installed on the left plate as an example to illustrate the application of the positioning structure.

[0036] Specifically, in this embodiment, through holes are provided on the left plate. A part of the positioning structure passes through the through holes and is connected to the positioning plate 10, and the other part is exposed outside the left plate. The part outside the left plate can be used to adjust the part inside the box body 3, so as to drive the positioning plate 10 to move along the set gauge of the guiding structure, realizing the pressing or loosening of the instrument.

[0037] When a positioning structure is also provided on the right plate, the two positioning plates 10 are arranged opposite to each other and can press the instrument from the left and right sides respectively, enabling the instrument to be centered, that is, arranged in the middle of the box body 3, thereby ensuring the balance of the drone during flight.

[0038] In an alternative embodiment, as Figures 7 - 13 shown, the adjusting structure 6 includes a first adjusting sleeve 622, a first adjusting bolt 623, a locking structure 621, and an adjusting knob 61. One end of the first adjusting sleeve 622 is fixedly connected to the positioning plate 10, and the other end of the first adjusting sleeve 622 has internal threads. One end of the first adjusting bolt is threadedly connected to the first adjusting sleeve 622, and the other end of the first adjusting bolt has the adjusting knob 61. The locking structure 621 connects the first adjusting bolt to the box body 3 and can limit the rotation of the first adjusting bolt.

[0039] In this embodiment, the first adjusting sleeve 622 and the first adjusting bolt are threadedly connected. By driving the first adjusting bolt to rotate through the adjusting knob 61, the distance between the positioning plate 10 and the left plate or the right plate can be adjusted, so as to adjust the position of the instrument and the pressure between the positioning plate 10 and the instrument, and finally realize the positioning and fixing of the instrument.

[0040] After the instrument is adjusted in place, the locking structure 621 is used to fix the first adjusting bolt 623 to prevent the first adjusting bolt 623 from rotating during use, thereby affecting the stability of the instrument.

[0041] Specifically, in this embodiment, the locking structure 621 is as Figure 10 and Figure 11As shown, it includes a locking block 625 with a T-shaped vertical cross-section and a locking spring 626. One end of the locking spring 626 abuts against the adjusting knob 61, and the other end abuts against the large head end of the locking block 625. The locking block 625 has a regular polygon-shaped limiting hole 6251, and the cross-sectional shape of the end of the first adjusting bolt 623 connected to the adjusting knob 61 is a corresponding regular polygon, so that the locking block 625 can be sleeved on the first adjusting bolt 623 and axially move along the first adjusting bolt 623; the outer contour of the small head end of the locking block 625 is a regular polygon, and the shape of the through hole on the left plate or the right plate is a regular polygon hole that matches it, so that the small head end of the locking block 625 can be pressed into the through hole under the action of the locking spring 626, and under the action of the through hole, the rotation of the locking block 625 is restricted, thereby achieving the effect of restricting the rotation of the first adjusting bolt 623.

[0042] When it is necessary to adjust the position of the positioning plate 10, pull the locking block 625 outwards. After pulling the locking block 625 out of the through hole, rotate the adjusting knob 61, and the first adjusting bolt 623 rotates synchronously with the locking block 625. A baffle 624 is fixed on the first adjusting bolt 623, and the baffle 624 is arranged inside the left plate or the right plate. At this time, the locking block 625 and the baffle 624 are respectively arranged inside and outside the left plate or the right plate, which can restrict the axial movement of the first adjusting bolt 623, so that the first adjusting bolt 623 can only rotate, and further can drive the first adjusting sleeve 622 to axially move, achieving the purpose of driving the positioning plate 10 to perform a linear displacement; when the adjustment is completed, finely adjust the rotation angle of the first adjusting bolt 623, release the locking block 625, so that the locking block 625 can enter the through hole to complete the rotation limit of the first adjusting bolt 623.

[0043] It can be understood that in this embodiment, the locking structure 621 is the above structure, but it is not limited to this setting method, and it can also be other locking methods, such as the snap button method, the nut locking method, etc. That is to say, as long as the rotation limit of the first adjusting bolt 623 can be achieved.

[0044] In an alternative embodiment, as Figure 4 、 Figure 5 and Figure 6 shown, the guiding structure includes a guiding groove provided inside the box body 3 and a guiding strip provided on the positioning plate 10; the guiding strip is slidably arranged in the guiding groove.

[0045] Specifically, in this embodiment, the bottom plate 7 of the box body 3 has guiding grooves, and there are two guiding grooves, respectively located near the front plate and the rear plate 5, which can ensure the balance of the positioning plate 10 during movement.

[0046] More specifically, in this embodiment, a rubber layer 71 is provided on the bottom plate 7. Through the provision of the rubber layer 71, sufficient friction is provided for the instrument, so as to achieve the positioning of the instrument together with the positioning plates 10 on the left and right sides, ensuring the stability of the instrument positioning.

[0047] In an alternative embodiment, as Figure 2 shown, the positioning structure further includes a memory foam board 11; the memory foam board 11 is provided on the side of the positioning plate 10 away from the adjustment structure 6.

[0048] In this embodiment, through the provision of the memory foam board 11, the shape of the instrument can be adapted, which can not only avoid the damage caused by the direct extrusion of the hard positioning plate 10 to the instrument, but also further ensure the positioning stability of the instrument.

[0049] In an alternative embodiment, as Figure 14 and Figure 15 shown, the fixing bracket 4 includes a rotating base 16, a length adjuster 17 and a hoop adjuster 18; the rotating base 16 is fixedly provided on the outer wall of the box body 3; one end of the length adjuster 17 is connected to the rotating base 16, and the other end is connected to the hoop adjuster 18; the hoop adjuster 18 is used to connect the length adjuster 17 to the unmanned aerial vehicle.

[0050] In this embodiment, the rotating base 16 is fixed outside the top plate 15 of the box body 3, the hoop adjuster 18 is fixedly connected to the bracket or rotor arm of the unmanned aerial vehicle, and the length adjuster 17 is used to connect the hoop adjuster 18 and the rotating base 16. After adjusting the length according to different types of unmanned aerial vehicles and the connection positions, the box body 3 is fixed on the unmanned aerial vehicle.

[0051] In this embodiment, the provision of the length adjuster 17 enables the box body 3 to be installed on different unmanned aerial vehicles, improving the selectivity of instrument carrying.

[0052] In an alternative embodiment, as Figures 16 - 19 shown, the rotating base 16 includes a lower base 162, an upper base 161 and a base connector 14; the base connector 14 is used to connect the lower base 162 to the box body 3; the upper base 161 is rotatably provided on the lower base 162 and is used to connect the length adjuster 17.

[0053] In this embodiment, the rotating base 16 is composed of an upper base 161, a lower base 162, a base angle fixing bolt 163, a steering limit gear 164, and a fixing nut 165. A length adjuster 17 is fixed on the upper side of the upper base 161. The upper base 161 is provided with an opening for the inner bolt of the length adjuster 17 to pass through. The lower side of the upper base 161 is connected to the lower base 162 through the base angle fixing bolt 163. The lower end of the base angle fixing bolt 163 has the lower base 162. There is a nut on the top of the lower base 162. The steering limit gear 164 is fixed to the bottom of the lower base 162. The steering limit gear 164 is connected to the base connector 14. The fixing nut 165 is used to tighten the bolt of the base connector 14 passing through the steering limit gear 164 and the lower base 162.

[0054] The lower end of the base connector 14 has a limit portion. One side of the limit portion close to the lower base 162 has a gear groove matching the steering limit gear 164. The steering limit gear 164 is fixed on the lower base 162. The limit portion of the base connector 14 is fixed on the top plate 15 of the box body 3. After passing through the steering limit gear 164 and the lower base 162, it is fixed by the fixing nut 165. At this time, the steering limit gear 164 falls into the gear groove, which can prevent the lower base 162 from rotating.

[0055] When it is necessary to adjust the angle of the lower base 162, after loosening the fixing nut 165, lift the rotating base 16 upward to drive the steering limit gear 164 to disengage from the gear groove of the base connector 14, so that the rotating base 16 can be rotated to adjust the angle. After the angle adjustment is completed, let the steering limit gear 164 fall into the gear groove of the base connector 14, and then fix it with the fixing nut 165.

[0056] In an alternative embodiment, as Figure 14 and Figure 15 shown, the length adjuster 17 includes a second adjusting bolt 172, a second adjusting sleeve 171, and a connecting structure; one end of the second adjusting sleeve 171 is fixedly connected to the rotating base 16, one end of the second adjusting bolt 172 is threadedly connected to the second adjusting sleeve 171, and the connecting structure is arranged at the other end of the second adjusting bolt 172. The connecting structure is used to connect the hoop adjuster 18.

[0057] Specifically, in this embodiment, the length adjuster 17 is adjusted in the way of a threaded sleeve. The upper base 161 is connected through the second adjusting sleeve 171. The hoop adjuster 18 is connected through the connecting structure on the second adjusting bolt 172. The distance between the hoop adjuster 18 and the rotating base 16 is realized by the threaded connection between the second adjusting bolt 172 and the second adjusting sleeve 171.

[0058] In this embodiment, asFigure 20 and Figure 21 As shown in and

[0059] , the connection structure includes a steering gear 173 and a steering fixator 174.

[0059] Specifically, in this embodiment, the steering gear 173 is a combination of a spherical structure and a connecting rod. The end of the connecting rod has an external thread and can be threadedly connected to the hoop adjuster 18. The other end of the connecting rod is integrally provided with the spherical structure to form an integral structure.

[0060] Specifically, in this embodiment, the steering fixator 174 is cylindrical, with internal threads provided therein, and a hole structure through which the connecting rod passes is provided at the bottom of the cylindrical structure.

[0061] More specifically, the aperture of the hole structure is larger than the diameter of the connecting rod and smaller than the diameter of the spherical structure, which can not only prevent the steering gear 173 from disengaging from the steering fixator 174, but also enable the steering gear 173 to rotate within a limited range in the steering fixator to adjust the angle between the connecting rod and the second adjusting bolt 172.

[0062] During installation, the connecting rod passes through the hole structure and is threadedly connected to the connection threaded hole 183 on the hoop adjuster 18. The spherical structure is restricted inside the cylindrical steering fixator 174. The steering fixator 174 is threadedly connected to the end of the second adjusting bolt 172 away from the second adjusting sleeve 171 through the internal threads. When the end of the second adjusting bolt 172 does not abut against the spherical structure, the steering gear 173 can be angle-adjusted. When the end of the second adjusting bolt 172 abuts against the spherical structure, the locking of the steering gear 173 is achieved.

[0063] In an alternative embodiment, as shown in Figure 22 , the hoop adjuster 18 includes a hoop band 184, a connection block 181, and a hoop tightening knob 182; both ends of the hoop band 184 are inserted into the connection block 181 and fixed by the hoop tightening knob 182 to achieve the diameter adjustment of the hoop band 184; a connection hole is provided on the side of the connection block 181 away from the hoop band 184, and the length adjuster 17 is fixedly connected to the connection block 181 through the connection hole. Figure 22 As shown in Figure 22 , the hoop adjuster 18 includes a hoop band 184, a connection block 181, and a hoop tightening knob 182; both ends of the hoop band 184 are inserted into the connection block 181 and fixed by the hoop tightening knob 182 to achieve the diameter adjustment of the hoop band 184; a connection hole is provided on the side of the connection block 181 away from the hoop band 184, and the length adjuster 17 is fixedly connected to the connection block 181 through the connection hole.

[0064] In this embodiment, the hoop adjuster 18 includes three parts: a connection block 181, a hoop tightening knob 182, and a hoop band 184. Among them, the connection block 181 has a threaded hole and can be threadedly connected to the connecting rod on the steering gear 173; the connection block 181 also has a locking hole. After both ends of the hoop band 184 are inserted into the locking hole, the hoop band 184 is locked by the hoop tightening knob 182.

[0065] When it is necessary to adjust the diameter of the hoop band 184, the hoop band 184 can be loosened by the hoop tightening knob 182 for adjustment. After adjusting to the appropriate position, it can be locked.

[0066] As can be seen from the above, the box body 3 is mainly composed of an adjusting structure 6, a positioning plate 10, a memory sponge plate 11, a rubber paving layer 71 and six panels. Both the bottom plate 7 and the top plate 15 have two first reserved grooves 8. The bottom plate 7 protrudes to form a fixed bottom support 12 for the front plate. The bottom of the front plate is placed in the second reserved groove 9 on the fixed bottom support 12 to limit the downward movement of the front panel. There are two lateral fixing devices 13 for the front plate on each adjacent side plate 51 to limit the lateral movement of the front panel, thereby fixing the front panel. The front panel can be supported and removed to provide a better detection environment.

[0067] In this embodiment, the installation process of the entire mounting and fixing device 2 is as follows: First, cover the buttons of the carried instrument to prevent the buttons from being squeezed during the fixing process. For instruments that cannot be remotely controlled, they need to be turned on at this time.

[0068] Secondly, pull out the front plate of the box body 3, then place the instrument on the rubber paving layer 71 inside the box body 3 and straighten its posture. Then, turn the adjustment knobs 61 respectively to adjust the position of the positioning plate 10. The adjustment progress of the two first adjustment bolts 623 is kept consistent, which not only ensures that the instrument can be placed in the center, but also avoids a certain first adjustment bolt 623 from sliding out of the first adjustment sleeve 622 due to being too long.

[0069] After that, the first adjustment sleeve 622 drives the rigid positioning plate 10 to move. The positioning plate 10 as a whole squeezes the flexible memory sponge plate 11, and the memory sponge plate 11 further squeezes the carried instrument. Under the action of the mutual force, the flexible memory sponge plate 11 will be squeezed into a shape close to the contour of the carried instrument. Then, by continuously adjusting the position of the positioning plate 10 and timely straightening the direction of the instrument, it is ensured that under the combined action of the two memory sponge plates 11 and the rubber paving layer 71, the instrument is stabilized without interfering with the normal operation of the detection end of the instrument. Then, the first adjustment bolt 623 is fixed through the locking structure 621.

[0070] Next, install the front plate of the box body 3 as needed. Installing the front plate of the box body 3 can improve the safety of the instrument, but it may affect the detection / measurement accuracy of the instrument.

[0071] Then, place the box body 3 on the multi-rotor UAV 1. The process is as follows: First, place the box body 3 flat on the ground, and then adjust the horizontal angle, inclination angle and the length of the adjusting rod of the fixed bracket 4.

[0072] Specifically, the horizontal angle of the fixing bracket 4 can be changed by adjusting the gear under the rotating base 16 at the bottom of the fixing bracket 4. After unscrewing the nut of the lower base 162, lift the fixing bracket 4 as a whole, and then rotate the bracket around the vertical direction until the angle is suitable for the hoop to overlap the rotor arm. Then lower the fixing bracket 4, and let the horizontal turning gear of the lower platform fall into the base connector 14 at the upper part of the box body 3, ensuring that the bolts in the base connector 14 can pass through the lower base 162, and then tighten the passed-through bolts with bolts to achieve the fixation of the horizontal angle.

[0073] Specifically, the inclination angle between the upper and lower platforms of the base can be changed by adjusting the upper and lower platform angle fixing bolts in the middle of the rotating base 16. First, lift the upper base 161 part, loosen the upper and lower platform angle fixing bolts, and then rotate the upper platform around the bolt axis until the angle is suitable for the hoop to overlap the rotor arm. Then fix the angle at this time, and then tighten the upper and lower platform angle fixing bolts to achieve the angle fixation.

[0074] Specifically, the length of the fixing bracket 4 can be changed by turning the length adjuster 17 in the middle of the bracket. The length of the length adjuster 17 is changed by turning the bolt inside the adjuster. There is a matching thread on the inner side of the adjuster housing, which restricts the movement of the bolt inside the adjuster along the axial direction while realizing the length adjustment. In addition, there is a base with a diameter larger than the opening diameter on the inner side of the adjuster housing at the bottom of the bolt inside the adjuster, ensuring that the bolt inside the adjuster will not break away from the adjuster housing.

[0075] Specifically, the change of the hoop orientation is realized by adjusting the steering gear 173 at the connection between the length adjuster 17 and the hoop. Put the steering gear 173 into the hole of the steering fixer 174, and then screw the threaded cylinder part into the threaded hole reserved on the hoop platform through the opening of the hole of the steering fixer 174. Then screw the steering fixer 174 together with the internal steering gear 173 onto the thread reserved at the end of the bolt inside the adjuster. Before tightening, ensure that the steering gear 173 is adjusted to an angle suitable for the hoop to overlap.

[0076] Then, loosen the bolts to open the four hoops respectively. Put one of the hoops on the rotor arm of the drone, and then tighten it by turning the bolt. At this time, keep the hoop hanging and do not tighten it temporarily. Then, adjust the length, inclination angle and horizontal angle of the adjuster by adjusting the telescopic rod and the adjusting platform in turn, so that the four hoops are hung on the rotor arms of the drone that are symmetrically arranged in pairs. Then adjust the hoop orientation and tighten the bolts to make the hoop clamp the rotor arm.

[0077] Finally, conduct a connection check to ensure that the drone, the box body 3, and the instrument and equipment are tightly connected.

[0078] In the second aspect, the present invention provides a drone, as Figure 1 shown, including the carrying and fixing device 2 described in any one of the foregoing embodiments.

[0079] For a quadrotor UAV, the fixing bracket 4 can be fixed to the rotor arm by adjusting the fixing bracket 4, the horizontal angle, the inclination angle, the length and the hoop orientation. The general operation process is the same as that of the foregoing embodiment.

[0080] For a hexarotor UAV, four rotor arms that are symmetric in pairs need to be selected for connecting the fixing bracket 4. The general operation process is the same as that of the foregoing embodiment.

[0081] For the large-bracket multi-rotor UAV 1, its bracket is likely to affect the fixing of the box body 3. Therefore, the carried device can be fixed on the rotor arm or the landing bracket. If it is fixed on the rotor arm, four rotor arms that are symmetric in pairs need to be selected, and the fixing operation is completed through the space between the landing brackets. The general operation process is the same as that of the foregoing embodiment.

[0082] If it is fixed on the landing bracket, a suitable fixing position needs to be selected first to ensure that the carried device does not loosen after being fixed. The general operation process is the same as that of the foregoing embodiment.

[0083] The beneficial effects of the embodiments of the present invention are as follows: The carried instrument is fixed on the box body 3 through the positioning structure, so that it can better adapt to different carried instruments. The box body 3 is fixed on the UAV through the fixing bracket 4, and the fixing bracket 4 can adapt to different UAVs, thereby improving the utilization rate of the UAV.

[0084] The foregoing is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
