Vehicle-mounted drones can quickly reach various work sites with the high maneuverability of the vehicle, and are widely used in many key areas, such as drones for high-altitude glass cleaning.

[0003] The sizes of existing drone storage devices are designed according to the size of the drone. For large drones, the on-board storage space is even more limited. In actual operation, when the drone lands and stops after performing a mission, it is difficult to accurately stop at the designated position of the storage device due to the influence of various factors such as wind, terrain, and sensor errors. The drone often deviates from the target position, which requires manual position adjustment to accurately place the drone in the storage device for subsequent closing operations. For this reason, a vehicle-mounted storage device for drones is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] Reference Figure 1-6As shown, a vehicle-mounted storage device for a drone comprises a storage box 1 with an open top and a box cover 2, wherein both outer walls of the storage box 1 are provided with slide grooves 11, and both inner walls of the box cover 2 are connected with a pair of slide bars 21, which are slidably connected with the two slide grooves 11. A driving mechanism is installed on the outer side of the storage box 1 for controlling the opening and closing of the box cover 2, and a position adjustment mechanism 3 is provided in the storage box 1 for automatically adjusting the storage position of the drone body 4 and limiting the movement of the drone body 4, and a roller 41 is provided on the bracket of the drone body 4 for facilitating position adjustment.

[0026] In this embodiment, the driving mechanism includes a pair of cylinders 22, which are installed on the outer walls of both sides of the storage box 1. The movable end of each cylinder 22 is rotatably connected to a gear 13. The outer walls of both sides of the storage box 1 are connected to a first straight rack 14 with a tooth surface facing upward, and the bottom surfaces of both sides of the box cover 2 are connected to a second straight rack 15 with a tooth surface facing downward. The gear 13 is engaged with the first straight rack 14 and the second straight rack 15 at the same time.

[0027] In this embodiment, the position adjustment mechanism 3 includes a movable plate 32, two parallel and symmetrical slide rails 31 are installed on the bottom inner wall of the storage box 1, the movable plate 32 is slidably connected to the slide rails 31, and a first motor 33 is installed on the bottom inner wall of the storage box 1. The output shaft of the first motor 33 is coaxially connected to a threaded rod 331, and the threaded rod 331 is connected to the movable plate 32 by a thread. A movable groove 321 is opened in the middle of the top surface of the movable plate 32, and the movable groove 321 is vertically distributed with the slide rail 31. The groove walls at both ends of the movable groove 321 are A rotating shaft 34 is connected for common rotation, and two threaded sections 342 are provided on the rotating shaft 34. Two moving blocks 35 are slidably connected in the moving groove 321. The two moving blocks 35 are respectively connected to the two threaded sections 342 on the rotating shaft 34 through threads. A hook plate 351 is connected to the top of the two moving blocks 35. A second motor 341 is installed on the side of the moving plate 32. One end of the rotating shaft 34 passes through the moving plate 32 and is coaxially connected to the output shaft of the second motor 341. A control unit for controlling the output direction of the first motor 33 is also provided in the storage box 1.

[0028] In this embodiment, the control unit includes two control boxes 36, and the two control boxes 36 are symmetrically mounted on the inner box wall on the same side of the storage box 1. A slider 361 is slidably connected in each of the control boxes 36, and a spring 362 is connected to the bottom of the slider 361. The lower end of the spring 362 is connected to the bottom box wall of the control box 36, and a pull rope 37 is connected to the bottom of the slider 36. A rope hole is provided at the bottom of the control box 36, and the end of the pull rope 37 away from the slider 361 passes through the rope hole and is connected to the inner box wall of the storage box 1 away from the control box 36. A conductive sheet 363 is embedded in the slider 361, and a conductive strip 364 is embedded on the inner box wall of one side of the control box 36. The conductive sheets 363 and the conductive strip 364 in the two control boxes 36 are electrically connected to the control circuit of the first motor 33 through wires, such as Figure 1 As shown, when the conductive sheet 363 near the upper control box 36 contacts the conductive bar 364 and is energized, the first motor 33 will be driven to rotate forward and the movable plate 32 will be driven to slide in the direction away from the first motor 33. When the conductive sheet 363 near the lower control box 36 contacts the conductive bar 364 and is energized, the first motor 33 will be driven to flip and the movable plate 32 will be driven to slide in the direction close to the first motor 33. The distance between the two pull ropes 37 is greater than the length of the bracket on the drone body 4. The bracket of the drone body 4 can only be in contact with one pull rope 37 at the same time.

[0029] In this embodiment, a limiting plate 38 is connected to the bottom of each control box 36 and located on the side of the rope hole away from the other control box 36. A limiting groove 381 is provided on each limiting plate 38. The pull rope 37 is connected to a limiting ball 371. When the pull rope 37 is not subjected to external force, the limiting ball 371 is just against the bottom surface of the control box 36.

[0030] In this embodiment, the two threaded segments 342 on the rotating shaft 34 have opposite thread rotation directions and the same length, and the notches of the hook plates 351 on the two moving blocks 35 face opposite directions and are away from each other.

[0031] The width of the limiting groove 381 is larger than the diameter of the limiting ball 371 and smaller than the diameter of the pull rope 37, so that the pull rope 37 can pass through the limiting groove 381 while the limiting ball 371 cannot pass through. The shape of the limiting plate 38 is as follows: Figure 4 As shown, when the pull rope 37 is pulled vertically, the limit plate 38 will not contact the limit ball 371. When the pull rope 37 is pulled horizontally, the pull rope 37 just enters the limit groove 381, and the limit ball 371 is against the limit plate 38, so that the pull rope 37 cannot continue to be pulled, and the spring 362 is always in a compressed state.

[0032] The working process and principle of the present invention are as follows:

[0033] During use, the entire storage box 1 is installed on the roof. When the drone body 4 is to be lowered and stopped, the cylinder 12 is first controlled to push the gear 13 to move. Through the engagement of the first spur rack 14, the gear 13 and the second spur rack 15, the box cover 2 is pushed to slide on the slide groove 11 so that the top of the storage box 1 becomes open. At this time, the operator can control the drone body 4 to fall so that the bracket of the drone body 4 falls on the movable plate 32.

[0034] After the drone is finished falling, the second motor 341 can be turned on to drive the rotating shaft 34 to rotate, and the two moving blocks 35 are controlled by the thread to slide in the direction away from each other, so that the two hook plates 351 move to both sides. If there is a lateral deviation of the drone body 4, one of the hook plates 351 will first contact the bracket of the drone body 4 during the movement, pushing the drone body 4 to move lateral. When the lateral deviation is corrected by movement, the stop position of the two hook plates 351 just hooks the two brackets of the drone body 4, thereby limiting the lateral displacement of the drone body 4; if there is a longitudinal deviation of the drone body 4, during the falling stage of the drone body 4, the bracket will press on the pull rope 37 on the deviation side, and the pull rope 37 will pull the control box after being pressed down. The slider 361 in 36 slides down, causing the conductive sheet 363 to contact the conductive strip 364, and the circuit of the first motor 33 is connected, driving the threaded rod 331 to rotate. The movable plate 32 is controlled by the thread to slide toward the other side of the compressed pull rope 37 to adjust the longitudinal deviation. When the movable plate 32 moves, the pull rope 37 will slide out from the bottom gap of the drone body 4 bracket. After the pull rope 37 is no longer compressed, the spring 362 will push the slider 361 to slide up to cut off the power to the first motor 33 and pull the pull rope 37 to return to a horizontal state. After the movable plate 32 stops sliding, it indicates that the drone body 4 has achieved the correction of the longitudinal deviation. At this time, the cylinder 12 can be controlled to work to make the box cover 2 slide back, and the storage box 1 can be closed to complete the storage of the drone body 4.

[0035] During the driving of the vehicle, there are two hook plates 351 horizontally to limit the drone body 4, and there are two pull ropes 37 on the longitudinal sides of the drone body 4. When the drone body 4 has a tendency to move longitudinally due to the driving of the vehicle, the bracket will horizontally squeeze the pull rope 37 on one side. When the pull rope 37 is pulled horizontally, the pull rope 37 will enter the limiting groove 381 of the limiting plate 38, but the limiting ball 371 is blocked by the limiting plate 38 to limit the pull rope 37 from being further pulled. At this time, the restricted pull rope 37 will play a role in limiting the longitudinal movement of the drone body 4, and provide better limiting protection for the vehicle-mounted drone body 4.

[0036] It is understood from common technical knowledge that the present invention may be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
