Description

Technical Field

[0001] The utility model relates to the technical field of remote sensing unmanned aerial vehicles, in particular to a remote sensing unmanned aerial vehicle cabin. Background Art

[0002] Remote sensing drones, that is, drones use sensors to collect electromagnetic wave information of target objects, identify the target objects after processing and analysis, and reveal their geometric and physical properties, relationships and laws of change. It is a modern scientific technology. It is mainly used for disaster monitoring, early warning, assessment, emergency rescue command systems, and civil fields. Current remote sensing drones often need to be equipped with cabin devices to carry and protect remote sensing equipment because they have to carry remote sensing equipment. However, most cabins in the existing technology are not convenient for rapid storage and release of remote sensing equipment, which makes it easy for remote sensing equipment to be accidentally damaged during takeoff and landing of the drone, which is not conducive to the normal operation of telemetry.

[0003] There are also existing technologies for storing remote sensing equipment, such as a mobile geographic information remote sensing mapping device and its use method with publication number CN117485614A, which includes a protective shell, which is fixed on the lower side of the fixed seat, and a mapping component is movably arranged in the protective shell. A driving component for driving the mapping component to rise and fall is arranged in the protective shell. When the drone is not performing mapping work, the mapping component is stored, and the mapping component is protected by the protective shell and the protective plate. However, the main components of the driving mapping component are basically located in the protective shell and need to be equipped with multiple motors, which occupy the internal space, and the protective plate needs to be opened and closed separately.

Moreover, one transmission shaft can be used to drive two sets of first transmission components to move simultaneously, thereby driving a pair of the screw rods to rotate, and then driving a pair of the vertical plates to rise and fall synchronously. This arrangement structure can reduce the number of transmission shafts and motors and ensure the synchronization of movement. 4. When the vertical plate lowers the support plate, the position and pitch angle of the remote sensing unit can also be adjusted.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] like Figure 1 to Figure 3 As shown, a remote sensing UAV cabin comprises a cabin 2 arranged below the UAV body 1, a liftable support plate 5 is provided below the cabin 2, and a remote sensing unit 6 is provided on the support plate 5; a pair of oppositely arranged side walls of the cabin 2 are respectively provided with slide grooves 3, and liftable vertical plates 4 are provided in the slide grooves 3, and the lower ends of a pair of vertical plates 4 extend from the side walls and are connected to the support plate 5; the cabin 2 is respectively provided with first chambers 8 above the slide grooves 3, and first transmission assemblies are respectively provided in the first chambers 8, and a pair of the first transmission assemblies are connected with a transmission shaft 10, and one end of the transmission shaft 10 is connected to a first motor 12 arranged outside the cabin 2; and the lower part of the first transmission assembly is respectively connected and driven with a screw rod 7, and the screw rod 7 penetrates into the slide groove 3 and is threadedly connected with the vertical plate 4.

[0027] The utility model improves the cabin of the remote sensing UAV so that the support plate 5 at the opening below the cabin 2 can be raised and lowered to quickly release the remote sensing unit 6 from the storage box, thereby preventing the UAV from causing accidental collision and damage to the remote sensing unit that is always exposed to the outside during takeoff or landing, so as not to affect the normal operation of the telemetry work.

[0028] The support plate 5 is matched with the opening below the cabin 2 to close the cabin; the space inside the cabin 2 is also matched with the remote sensing unit 6 to ensure that the cabin 2 can normally accommodate the remote sensing unit 6 when the support plate 5 is raised and closed.

[0029] The coordinated arrangement of the slide groove 3 and the vertical plate 4 avoids the need to arrange lifting components outside or inside the cabin, thereby avoiding the exposure of lifting components, transmission components, etc. and also avoiding their occupying space inside the cabin.

[0030] By utilizing the threaded connection between the screw rod 7 and the vertical plate 4 and cooperating with the limit of the slide groove 3, the rotational movement of the screw rod 7 can be converted into the lifting linear movement of the vertical plate. This structure is simple and practical. The design of the first chamber 8 can better accommodate the first transmission component, and the first transmission component can be used to convert the rotational movement of the transmission shaft into the rotational movement of the screw rod. Moreover, one transmission shaft can be used to drive two sets of first transmission components to move simultaneously, thereby driving a pair of the screw rods to rotate, and then driving a pair of the vertical plates to rise and fall synchronously, thereby realizing the lifting movement of the support plate. This arrangement structure can not only reduce the number of transmission shafts and motors, but also ensure the synchronization of movement.

[0031] Furthermore, a threaded hole 401 is provided in the vertical plate 4, and the lower end of the screw rod 7 is connected to the threaded hole 401, so that the screw rod and the vertical plate form a structure similar to a screw rod sleeve; the length of the screw rod 7 is greater than the length of the slide groove 3, ensuring that the screw rod 7 is still connected to the threaded hole 401 at the lower limit position, and the end of the vertical plate 4 is still in the slide groove 3.

[0032] Furthermore, guide limit grooves 301 are respectively provided on the inner walls on both sides of the slide groove 3 , and sliders 402 are respectively provided on both sides of the vertical plate 4 , and the sliders 402 are slidably disposed in the guide limit grooves 301 .

[0033] The guide limiting groove 301 and the slide block 402 can prevent the vertical plate 4 from being separated from the slide groove, and at the same time guide and limit the lifting movement of the vertical plate 4, which is beneficial to improving the stability and accuracy of its movement.

[0034] Furthermore, the first transmission assembly includes a first bevel gear 9 disposed on the upper end of the screw rod 7 , and a second bevel gear 11 sleeved on the transmission shaft 10 , and the second bevel gear 11 is meshedly connected with the first bevel gear 9 .

[0035] A pair of mutually cooperating bevel gear structures can effectively convert horizontal rotational motion into vertical rotational motion. In other embodiments, the first transmission assembly can also be a worm gear transmission form, and the worm gear is respectively installed on the lead screw and the transmission shaft.

[0036] For the cabin, a second through hole is penetrated between the two first chambers 8, and the transmission shaft 10 rotates and penetrates the second through hole. By setting the second through hole and the bearing, it is convenient to support and limit the transmission shaft 10. A third through hole is penetrated on the inner wall of one side of one of the first chambers 8, and the output shaft of the first motor 12 rotates and penetrates the third through hole. By setting the third through hole and the bearing, the output shaft of the first motor 12 is limited and supported. A fourth through hole is penetrated between the slide groove 3 and the corresponding first chamber 8, and the screw rod 7 rotates and penetrates the fourth through hole. By setting the fourth through hole and the bearing, it is convenient to support and limit the screw rod 7.

[0037] In some embodiments, Figure 4 and Figure 5 As shown, the vertical plate 4 is arranged at the middle position of the side wall, and the support plate 5 is rotatably arranged between a pair of the vertical plates 4, so that the support plate 5 can be rotated, thereby realizing the pitch and roll position control of the remote sensing unit.

[0038] Furthermore, a first through hole 13 is provided at the bottom of the vertical plate 4, and a rotating shaft 14 is provided on both sides of the vertical plate 4, and one end of the rotating shaft 14 is rotatably installed in the first through hole 13; a second chamber 15 is also provided at the bottom of one of the vertical plates 4, and the second chamber 15 is connected to the first through hole 13, and a second transmission assembly connected to the rotating shaft is provided in the second chamber 15, and a second motor 17 connected to and drives the second transmission assembly is provided on the outer side of the vertical plate 4.

[0039] Through the above arrangement, when the vertical plate 4 lowers the support plate 5, the position and pitch angle of the remote sensing unit 6 can also be adjusted. On the one hand, it can prevent the closed structure of the cabin 2 from blocking the remote sensing unit, and on the other hand, it can also improve the viewing angle range of the remote sensing unit, which is conducive to remote sensing operations.

[0040] For the vertical plate 4, a circular hole is penetrated on the inner wall of one side of the second chamber 15, and the output shaft of the second motor 17 rotates and penetrates the circular hole. By setting the circular hole and the bearing, it is convenient to limit and support the output shaft of the second motor 17; similarly, a bearing can also be set in the first through hole to support the rotating shaft; the rotating shaft can be two short shafts respectively connected to the two ends of the support plate, or it can be a long shaft running through the support plate.

[0041] Furthermore, the second transmission assembly includes a first gear 16 sleeved on the rotating shaft 14, and a second gear 18 connected to the output end (such as the output shaft) of the second motor 17, and the first gear 16 is meshed and connected with the second gear 18. Transmission can be achieved through the meshing of a pair of gears, or in the form of a coupling or a synchronous pulley.

[0042] Furthermore, a main controller and a power supply are also provided in the drone body 1, and the first motor 12 and the second motor 17 are electrically connected to the main controller respectively, so that the drone operator can control the two motors to realize the functions of lifting and rotating adjustment; the power supply can be a lithium battery configured for the drone, which is connected to the first motor 12 and the second motor 17 to power them.

[0043] When the cabin of the remote sensing UAV is in use, the remote sensing unit 6 is first installed above the support plate 5, and then the first motor 12 is turned on. The output shaft of the first motor 12 drives the corresponding second bevel gear 11 to rotate, and the second bevel gear 11 drives the transmission shaft 10 to rotate, and the transmission shaft 10 drives another second bevel gear 11 to rotate, and the two second bevel gears 11 respectively drive the corresponding first bevel gear 9 to rotate, and the first bevel gear 9 drives the screw rod 7 to rotate, and the screw rod 7 drives the corresponding vertical plate 4 to slide into the slide groove 3, so that the support plate 5 is driven up by the two vertical plates 4 until it contacts the bottom of the cabin 2, and at the same time, the support plate 5 drives the remote sensing unit 6 to enter the cabin 2, so that the remote sensing unit 6 is stored and protected. Through this arrangement, it is convenient to quickly operate the remote sensing equipment. The storage box is released quickly, so as to prevent accidental collision and damage to the remote sensing equipment during the take-off or landing phase of the drone, which is conducive to the normal operation of the remote sensing work. When the remote sensing equipment is released from the cabin 2, the second motor 17 is turned on, and the output shaft of the second motor 17 drives the second gear 18 to rotate in the second chamber 15, so that the first gear 16 is driven to rotate, and the first gear 16 drives the corresponding rotating shaft 14 to rotate, so that the support plate 5 is driven to rotate, and at the same time, the support plate 5 drives another rotating shaft 14 and the remote sensing unit 6 to rotate, so that the remote sensing unit 6 is rotated under the support plate 5, and then the terrain information can be collected. Through such a setting, it is convenient to rotate and adjust the remote sensing equipment, so as to prevent the closed structure of the cabin 2 from blocking the remote sensing equipment, and thus facilitate the remote sensing operation.
