Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted drone technology, specifically a vehicle-mounted drone device for road-based drone patrol. Background Technology

[0002] Road surface drone patrol refers to the activity of using drones equipped with high-definition cameras, infrared thermal imagers, multispectral sensors, and other equipment to conduct aerial inspections and checks on traffic infrastructure such as highways, urban roads, and bridges. Its main purpose is to monitor road conditions in real time, promptly detect abnormalities such as road surface damage, traffic congestion, and violations, and provide accurate information for traffic management and decision-making. With its efficiency, flexibility, and intelligence, road surface drone patrol technology is gradually becoming an important tool in the field of traffic management, which requires the use of vehicles to carry drones and move them through cities.

[0003] A search revealed problems with existing vehicle-mounted drone devices. Due to the curvature of some vehicle roofs, mounting the drone take-off and landing platform can be difficult. Therefore, a common practice is to use brackets to secure the drone to the roof rack. However, this method is cumbersome, and some vehicles lack roof racks, resulting in poor installation and hindering subsequent use by staff. Therefore, based on the above research and existing technologies, this paper proposes a road-based vehicle-mounted drone patrol device to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle-mounted device for unmanned aerial vehicle (UAV) patrol based on road surface, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vehicle-mounted device for road-based drone patrol includes: a housing with a lid rotatably connected to its top surface, a support frame slidably connected inside the housing, a support platform for supporting the drone mounted on the bottom surface of the support frame, two support plates slidably connected to the bottom surface of the support platform, and clamps for limiting the drone's movement fixedly mounted on the top surface of the support plates; and an installation structure disposed on the bottom surface of the housing for mounting the housing on a vehicle roof.

[0007] Furthermore, the mounting structure includes a movable plate, the bottom surface of which is rotatably connected to two connecting rods, and the bottom surface of the housing is slidably connected to two snap-fit ​​plates. One end of each connecting rod is rotatably connected to the bottom surface of the snap-fit ​​plate. An electric push rod is installed on the bottom surface of the housing to drive the snap-fit ​​plates to move. Two mounting slots are symmetrically opened on both sides of the housing. A support rod is fixedly installed inside the mounting slot. An mounting block is slidably connected to the outer circular wall of the support rod. A snap-fit ​​post is fixedly installed on the bottom surface of the mounting block. The snap-fit ​​post is movably snapped into the snap-fit ​​plate. A spring is sleeved on the outer circular wall of the support rod. A suction cup is universally connected to the bottom surface of the snap-fit ​​post.

[0008] Furthermore, mounting bases are fixedly installed on both sides of the housing, and a support box is rotatably connected inside the mounting base. A connecting plate is slidably connected inside the support box, and a suction cup is universally connected to the bottom surface of the connecting plate. A screw for locking the position of the connecting plate is threadedly connected to one side of the support box.

[0009] Furthermore, a positioning frame is fixedly installed on one side of the housing, and a magnet for limiting the position of the support box is fixedly installed on the inner side of the positioning frame.

[0010] Furthermore, a bidirectional lead screw is rotatably connected to one side of the bearing platform, and the bidirectional lead screw is threadedly connected to the support plate. A drive motor for driving the bidirectional lead screw to rotate is fixedly installed on one side of the bearing platform. A limiting strip is fixedly installed on the bottom surface of the support frame, and the support plate is slidably connected to the limiting strip.

[0011] Furthermore, an electric push rod for driving the support frame to move is fixedly installed on the inner bottom surface of the box. Restriction holes are opened on both sides of the inner side of the box, and restriction blocks are fixedly installed on both sides of the support frame. The restriction blocks are slidably connected to the restriction holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By using the box, snap-fit ​​post, suction cup 2, mounting block, mounting groove, support rod and spring in combination, it can adapt to the roof with different curvatures and the height of the snap-fit ​​post and suction cup 2 can also adapt to the body.

[0014] By using the box, suction cup 2, electric push rod 2, snap-fit ​​plate, connecting rod, movable plate and snap-fit ​​in a coordinated manner, the suction cup 2 can be kept attached to the roof of the vehicle.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In one typical implementation of this application, please refer to Figures 1-6A vehicle-mounted device for road-based drone patrol includes a housing 1. A cover 2 is rotatably connected to the top surface of the housing 1 via a hinge. A support frame 5 is slidably connected inside the housing 1. A support platform 6 for supporting the drone is installed on the bottom surface of the support frame 5 via multiple columns. Two support plates 26 are slidably connected to the bottom surface of the support platform 6. A clamp 27 for limiting the drone is fixedly installed on the top surface of the support plate 26. Notches are provided on both sides of the support platform 6. The support plates 26 are slidably connected to the notches. After the support plates 26 and clamp 27 move into the notches, they can continue to move inward until the clamp 27 contacts the drone. An installation structure 4 is set on the bottom surface of the housing 1 for mounting the housing 1 on the roof of a vehicle.

[0024] The mounting structure 4 includes a movable plate 18, which is rotatably connected to the bottom surface of the housing 1 via bearings. Two connecting rods 21 are rotatably connected to the bottom surface of the movable plate 18 via a rotating shaft. Two snap-fit ​​plates 20 are slidably connected to the bottom surface of the housing 1. Multiple snap-fit ​​teeth are provided on one side of the snap-fit ​​plates 20. One end of the connecting rod 21 is rotatably connected to the bottom surface of the snap-fit ​​plates 20 via a rotating shaft. An electric push rod 29 for driving the snap-fit ​​plates 20 to move is installed on the bottom surface of the housing 1. One end of the telescopic shaft of the electric push rod 29 is fixedly connected to one side of the snap-fit ​​plate 20 located on the left side.

[0025] Among them, the telescopic axis of the electric push rod 19 moves outward, causing the left snap-fit ​​plate 20 to move outward. The outward movement of the left snap-fit ​​plate 20, through the cooperation of the movable plate 18 and the connecting rod 21, causes the right snap-fit ​​plate 20 to move outward.

[0026] Two mounting slots 29 are symmetrically opened on both sides of the housing 1. A support rod 31 is fixedly installed inside the mounting slot 29. A mounting block 30 is slidably connected to the outer circular wall of the support rod 31. A snap-fit ​​post 22 is fixedly installed on the bottom surface of the mounting block 30. The snap-fit ​​post 22 is movably snapped into the snap-fit ​​plate 20. Multiple slots are opened on one side of the snap-fit ​​post 22. The snap-fit ​​post 22 and the snap-fit ​​plate 20 are snapped into each other through snap teeth and slots.

[0027] A spring 32 is fitted on the outer circular wall of the support rod 31. The spring 32 can provide elastic force to the mounting block 30. One end of the spring 32 is fixedly connected to the top surface of the mounting block 30, and the other end of the spring 32 is fixedly connected to the inner top surface of the mounting groove 29. The bottom surface of the snap-fit ​​post 22 is connected to a suction cup 23 through a universal joint. The suction cup 23 can be adsorbed onto the roof of the vehicle. The connection between the snap-fit ​​post 22 and the suction cup 23 through the universal joint makes it convenient for the suction cup 23 to adhere to the curved roof of the vehicle.

[0028] When the box body 1 and the box cover 2 are placed on the roof of the vehicle, the suction cup 23 is attached to the roof of the vehicle by the action of the universal joint. At the same time, the box body 1 moves downward, which compresses the spring 32. At this time, the electric push rod 19 drives the two locking plates 20 to move outward and lock with the locking post 22, thus determining the position of the locking post 22 and the suction cup 23.

[0029] Two sliding grooves 10 are provided on the bottom surface of the housing 1. A slider 11 is slidably connected to the top surface of the snap-fit ​​plate 20. The slider 11 is wider at the top and narrower at the bottom. The slider 11 is slidably connected to the sliding grooves 10. When the snap-fit ​​plate 20 moves, it will cause the slider 11 to slide inside the slider 11 on the bottom surface of the housing 1. The sliding grooves 10 and the slider 11 cooperate to restrict the movement of the snap-fit ​​plate 20, thereby achieving the effect of restricting the snap-fit ​​plate 20. A PLC controller is fixedly installed on one side of the housing 1. The electric push rod 19 is electrically connected to the PLC controller.

[0030] Preferably, the housing 1 is installed on the roof of a vehicle during road patrol using a drone. When the staff places the housing 1 on the roof, the suction cup 23 on the bottom of the snap-fit ​​post 22 will adhere to the roof and be attached to it under the action of the universal joint. At the same time, the weight of the housing 1 will also cause the housing 1 to move downward. The downward movement of the housing 1 causes the mounting block 30 to move along the support rod 31 inside the mounting groove 29 and the spring 32 to be compressed. Due to the curvature of the roof, the height of different parts of the roof is not consistent. The cooperation of the mounting block 30, the support rod 31, the spring 32, the snap-fit ​​post 22 and the suction cup 23 allows multiple sets of snap-fit ​​posts 22 and suction cup 23 to move to different heights to adapt to the different heights of different positions on the roof. Moreover, the suction cup 23 has a high degree of freedom and can adapt to different curvatures on the roof, making it highly adaptable.

[0031] Furthermore, after the housing 1 is attached to the roof of the vehicle by multiple suction cups 23, the PLC controller activates the electric push rod 19. The telescopic axis of the electric push rod 19 moves outward, causing the left-side locking plate 20 to move outward. The outward movement of the left-side locking plate 20 causes the left-side connecting rod 21 to move outward, while simultaneously causing the movable plate 18 to rotate. The rotation of the movable plate 18 causes the right-side connecting rod 21 and locking plate 20 to move outward. The two locking plates 20 move outward and engage with the locking post 22, preventing the locking post 22 from moving due to vehicle bumps and the action of the spring 32. This ensures that the suction cups 23 are always attached to the roof of the vehicle, thus ensuring a firm installation even when the roof is curved. This achieves the desired installation effect for the housing 1, making it convenient for staff to use any vehicle to carry the housing 1 and drones for road patrols.

[0032] In addition, when the roof is flat, multiple suction cups 23 will directly adhere to it, and the snap-fit ​​plate 20 will also snap into the snap-fit ​​post 22.

[0033] Mounting bases 12 are fixedly installed on both sides of the housing 1. A support box 3 is rotatably connected inside the mounting base 12 via a rotating shaft. A connecting plate 13 is slidably connected inside the support box 3. A suction cup 17 is connected to the bottom surface of the connecting plate 13 via a universal joint. The suction cup 17 can be used to adsorb the roof of the vehicle. A screw 16 for locking the position of the connecting plate 13 is threadedly connected to one side of the support box 3.

[0034] In this process, after the box 1 is installed on the roof, the suction cup 17 is moved outward to a suitable position by moving the connecting plate 13 outward. Then, the suction cup 17 is adjusted so that it is attached to the roof. The connecting plate 13 and the support box 3 can support the box 1 and improve its stability.

[0035] The support box 3 has several round holes on one side, and the connecting plate 13 has a threaded groove on one side. One end of the screw 16 passes through the round holes and is threaded to the inner wall of the threaded groove.

[0036] The operator moves the connecting plate 13 along with the suction cup 17 outward to a suitable position, then puts the screw 16 into the appropriate round hole and rotates the screw 16 so that one end of the screw 16 enters the thread groove, thus determining the position of the connecting plate 13.

[0037] Preferably, after the box 1 is installed on the roof of the vehicle, the operator rotates the support box 3 outward and moves the connecting plate 13 along with the suction cup 17 to a suitable position. Then, the operator places the screw 16 on the support box 3 to determine the position of the connecting plate 13 and the suction cup 17. The operator then rotates the suction cup 17 below the connecting plate 13 so that the suction cup 17 is attached to the roof of the vehicle. At this time, the support box 3, the connecting plate 13, and the suction cup 17 form a triangle with the box 1, which is more stable and reduces the shaking of the box 1 on the roof of the vehicle.

[0038] A positioning frame 14 is fixedly installed on one side of the housing 1. A magnet 15 for limiting the position of the support box 3 is fixedly installed on one side inside the positioning frame 14. The support box 3 has a hollow rectangular iron structure and an open bottom. The magnet 15 can attract the support box 3 and limit its rotation.

[0039] Preferably, when the housing 1 is not in use, the operator can rotate the support box 3 and the connecting plate 13 inwards so that the support box 3 enters the interior of the positioning frame 14. At this time, the magnet 15 inside the positioning frame 14 can attract the support box 3, preventing the support box 3 from rotating randomly and facilitating the storage of the support box 3 and the connecting plate 13.

[0040] A double-acting lead screw 25 is rotatably connected to the inside of the bearing platform 6 via a bearing. The double-acting lead screw 25 is threadedly connected to the support plate 26. A drive motor 24 for driving the double-acting lead screw 25 is fixedly installed on the inside of the bearing platform 6. One end of the drive shaft of the drive motor 24 is connected to one end of the double-acting lead screw 25 via a coupling. The drive motor 24 is electrically connected to the PLC controller.

[0041] The drive motor 24 drives the bidirectional lead screw 25 to rotate. The rotation of the bidirectional lead screw 25 causes the two sets of support plates 26 and clamping plates 27 to move inward until they abut against the bracket on the bottom of the drone. A limiting strip 28 is fixedly installed on the inner bottom surface of the support frame 5. The bottom surface of the limiting strip 28 has a groove that matches the limiting strip 28. The groove is slidably connected to the support plate 26.

[0042] Preferably, with the provided support platform 6, after the drone lands on the support platform 6, the PLC controller starts the drive motor 24. The drive shaft of the drive motor 24 rotates, causing the bidirectional lead screw 25 to rotate. The rotation of the bidirectional lead screw 25 causes the two sets of support plates 26 and clamping plates 27 to move inward along the limiting strip 28 into the notch on the support platform 6 and continue to move inward until they abut against the support on the bottom of the drone. The limiting strip 28 can restrict the movement of the support plates 26 and clamping plates 27, thereby using the clamping plates 27 to restrict the drone and prevent the drone from falling off the support platform 6.

[0043] An electric push rod 9 for driving the support frame 5 to move is fixedly installed on the bottom surface of the inner side of the housing 1. The top surface of the telescopic shaft of the electric push rod 9 is fixedly connected to the bottom surface of the support frame 5. The electric push rod 9 is electrically connected to the PLC controller. Limiting holes 7 are opened on both sides of the inner side of the housing 1. Limiting blocks 8 are fixedly installed on both sides of the support frame 5. The limiting blocks 8 are slidably connected to the limiting holes 7.

[0044] Preferably, when the drone is recovered using the support platform 6, the telescopic axis of the electric push rod 9 moves outward, causing the support frame 5 and the support platform 6 to move outward. The outward movement of the support frame 5 causes the limiting block 8 to slide inside the limiting hole 7 on the inner side of the housing 1. The limiting hole 7 and the limiting block 8 cooperate to restrict the movement of the support frame 5. The electric push rod 9 moves the support platform 6 above the housing 1. After the drone lands on the support platform 6, the electric push rod 9 drives the support platform 6 and the drone to reset and enter the interior of the housing 1, which facilitates the recovery of the drone used for road patrol.

[0045] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
