Description

Technical Field

[0001] This utility model belongs to the field of radar scanning technology, specifically relating to a high-precision radar scanning device mounted on an unmanned aerial vehicle. Background Technology

[0002] With the rapid development of drone technology and radar scanning technology, drones equipped with radar scanning capabilities are being used more and more widely. Radar is also known as radio positioning. Radar is an electronic device that uses electromagnetic waves to detect targets. Radar emits electromagnetic waves to illuminate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the rate of change of distance, azimuth, and altitude.

[0003] However, the radar scanners on existing drones are all fixed in position, making it inconvenient to disassemble and reassemble them. Furthermore, the angle of the radar scanner is fixed after installation, so changing the radar monitoring angle requires adjusting the drone's flight angle, which is inconvenient in operation. To address this, we propose a high-precision radar scanning device mounted on a drone. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision radar scanning device for drones, in order to solve the problems mentioned in the background art, where the radar scanning heads on existing drones are fixed in position, making it inconvenient to disassemble and reassemble them. Furthermore, the angle of the radar scanning head is fixed after installation, so changing the radar monitoring angle requires adjusting the drone's flight angle, which is inconvenient in operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-precision radar scanning device mounted on a drone includes a protective cover. Mounting rings are provided on both the left and right sides of the protective cover. Each mounting ring includes two opposing semi-circular fixing rings. Fixing bolts are threaded onto both ends of each semi-circular fixing ring. An assembly base is fixedly mounted on the outer surface of one of the semi-circular fixing rings. Assembly plates are fixedly mounted on both the left and right sides of the protective cover. An assembly groove is formed on the surface of the assembly base for the assembly plate to be inserted. The lower surface of the protective cover has an opening. An upper mounting plate is provided on the inner wall of the protective cover. Sliding grooves are formed on both the left and right sides of the inner wall of the protective cover. An assembly plate is fixedly mounted on both the left and right sides of the upper mounting plate. A sliding plate is slidably mounted on the inner wall of a sliding groove on the same side. A motor is fixedly mounted on the inner wall of one side of the sliding groove. A threaded rod is fixedly mounted on the end of the output shaft of the motor. A sliding plate on the same side as the threaded rod is threaded onto the outer surface of the threaded rod. A motor is fixedly mounted on the surface of an upper mounting plate. An upper mounting plate is fixedly mounted on the end of the output shaft of the motor. Two lower mounting plates are fixedly mounted on the lower surface of the upper mounting plate. A rotating shaft is rotatably mounted between the two lower mounting plates. A motor is fixedly mounted on the side of one of the lower mounting plates. The output shaft of the motor is fixedly connected to the rotating shaft. A mounting seat is fixedly mounted on the outer surface of the rotating shaft. A radar scanning head is fixedly mounted on the lower surface of the mounting seat.

[0006] The above scheme uses two semi-circular fixing rings to form a mounting collar, which is then fitted onto the outside of the UAV's leg support. The protective cover and mounting collar are assembled using an assembly base and assembly plate with a clamping plate, facilitating convenient assembly of the radar scanner head and subsequent disassembly. The radar scanner head is located inside the protective cover; when the radar scanner head moves downwards out of the cover, the cover provides installation protection. When not in use, the radar scanner head is retracted, preventing external interference with the UAV's takeoff and landing. By using motor two in conjunction with motor three, motor two drives the upper mounting plate to rotate horizontally, which in turn drives the radar scanner head to rotate horizontally via the lower mounting plate and mounting base. Motor three drives the mounting base to rotate the radar scanner head vertically, allowing for multi-angle and multi-directional scanning operations without changing the UAV's flight direction.

[0007] In the above scheme, it should be noted that motor one, motor two, motor three, contact switch and radar scanning head are all electrically connected to the UAV's built-in power supply.

[0008] In a preferred embodiment, the side of the assembly plate is provided with a groove, and a spring is fixedly installed on the inner wall of the groove. A retaining plate is fixedly installed at the end of the spring, and a retaining hole is provided on the side of the assembly base for the retaining plate to be inserted.

[0009] By using the above solution, the groove, the elasticity of the spring, and the use of the locking plate can be used to lock and unlock the assembly base and the assembly plate by locking or unlocking the locking plate into or out of the locking hole. The structure is simple and the operation is convenient.

[0010] In a preferred embodiment, the inner wall of the spring is provided with a telescopic rod, and the two ends of the telescopic rod are fixedly connected to the inner wall of the groove and the side of the card plate, respectively.

[0011] Using the above solution, the telescopic rod can support and guide the movement of the card plate, improve the stability of the movement, prevent shaking, and ensure good assembly stability between the assembly base and the assembly plate.

[0012] In a preferred embodiment, the side of the card plate has an inclined surface.

[0013] By adopting the above solution and setting an inclined surface, when the assembly plate is inserted into the assembly slot on the assembly base, the card plate will move into the groove on its own due to the presence of the inclined surface, thus improving the convenience of the assembly operation.

[0014] In a preferred embodiment, a plurality of guide rods are fixedly installed on the inner wall of the sliding groove of the protective cover, and the sliding plate is slidably installed on the outer surface of the plurality of guide rods at the same position.

[0015] By adopting the above scheme, the guide rod can support and guide the sliding plate during its up and down sliding process, improve the stability of the movement, and prevent wobbling.

[0016] In a preferred embodiment, a support shaft is fixedly installed at the end of the threaded rod, and the support shaft is rotatably installed on the inner wall of the sliding groove at the same position.

[0017] By adopting the above scheme, the support shaft can provide stable support for the rotation of the threaded rod, and prevent the threaded rod end from shaking during rotation.

[0018] In a preferred embodiment, the upper surface of the upper mounting plate is provided with a plurality of arc-shaped sliders arranged in a circular array, and the lower surface of the upper mounting plate is provided with an annular groove. The arc-shaped sliders are slidably mounted on the inner wall of the annular groove. The cross-sections of the arc-shaped sliders and the annular groove are both trapezoidal.

[0019] By adopting the above scheme, the sliding of the arc-shaped slider in the annular groove can ensure the stable rotation of the upper mounting plate and improve stability. By setting the arc-shaped slider with a trapezoidal cross section and the annular groove, the phenomenon of up and down movement of the upper mounting plate during rotation can be avoided.

[0020] In a preferred embodiment, a contact plate is fixedly installed on the outer surface of the rotating shaft, a mounting ring is fixedly installed on the lower surface of the upper mounting plate, and two contact switches are fixedly installed on the inner wall of the mounting ring. The contact switches are used in conjunction with the contact plate and are electrically connected to the motor.

[0021] Using the above scheme, the contact plate is used in conjunction with the mounting ring. When the shaft rotates, it drives the contact plate to rotate synchronously. When the contact plate touches the contact switch on one side, the contact switch controls the motor to reverse three times, realizing repeated oscillation within an arc range to achieve scanning within a certain range.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The high-precision radar scanning device on this drone uses two semi-circular fixing rings to form a mounting collar. The mounting collar is fitted onto the outside of the drone's leg support. The protective cover can be assembled with the mounting collar using an assembly base and assembly plate with a clamping plate. This facilitates the convenient assembly and disassembly of the radar scanning head. The radar scanning head is located inside the protective cover. When the radar scanning head moves downward out of the protective cover, the protective cover provides a protective installation effect. When not in use, the radar scanning head can be retracted, which also prevents the external radar scanning head from affecting the drone's take-off and landing.

[0024] The high-precision radar scanning device on this drone uses a combination of motor two and motor three. Motor two drives the upper mounting plate to rotate horizontally, which in turn drives the radar scanning head to rotate horizontally through the lower mounting plate and mounting base. Motor three drives the mounting base to drive the radar scanning head to rotate vertically. This allows the drone to perform multi-angle and multi-directional scanning operations without changing its flight direction. Attached Figure Description

[0032] Please see Figure 1-6 This utility model provides a high-precision radar scanning device for use on a drone, including a protective cover 1. Mounting collars are provided on both the left and right sides of the protective cover 1. Each mounting collar includes two opposing semi-circular fixing rings 2. Fixing bolts 3 are threaded onto both ends of each semi-circular fixing ring 2. An assembly base 4 is fixedly mounted on the outer surface of one of the semi-circular fixing rings 2. Assembly plates 5 are fixedly mounted on both the left and right sides of the protective cover 1. Assembly slots for the assembly plates 5 to be inserted are provided on the surface of the assembly base 4. The lower surface of the protective cover 1 has an opening. An upper mounting plate 6 is provided on the inner wall of the protective cover 1. Sliding grooves are provided on both the left and right sides of the inner wall of the protective cover 1. Sliding plates 7 are fixedly mounted on both the left and right sides of the upper mounting plate 6, and the sliding plates 7 are slidably mounted on the same side. The inner wall of the sliding groove is fixedly installed with a motor 8 on one side. A threaded rod 9 is fixedly installed at the end of the output shaft of the motor 8. A sliding plate 7 on the same side as the threaded rod 9 is threaded onto the outer surface of the threaded rod 9. A motor 10 is fixedly installed on the surface of the upper mounting plate 6. An upper mounting plate 11 is fixedly installed at the end of the output shaft of the motor 10. Two lower mounting plates 12 are fixedly installed on the lower surface of the upper mounting plate 11. A rotating shaft 13 is rotatably installed between the two lower mounting plates 12. A motor 14 is fixedly installed on the side of one of the lower mounting plates 12. The output shaft of the motor 14 is fixedly connected to the rotating shaft 13. A mounting seat 15 is fixedly installed on the outer surface of the rotating shaft 13. A radar scanning head 16 is fixedly installed on the lower surface of the mounting seat 15.

[0033] Two semi-circular fixing rings 2 are used to form a mounting collar, which is then fitted onto the outside of the UAV's leg support. The protective cover 1 and the mounting collar can be assembled using the assembly base 4 and assembly plate 5 with the clamping plate 19, thus facilitating the convenient assembly of the radar scanning head 16 and making subsequent disassembly and assembly easier. The radar scanning head 16 is located inside the protective cover 1. When the radar scanning head 16 moves downward out of the protective cover 1, the protective cover 1 provides a protective installation effect. When not in use, the radar scanning head 16 can be retracted, preventing external interference with the UAV's take-off and landing. By using motor 2 10 in conjunction with motor 3 14, motor 2 10 drives the upper mounting plate 11 to rotate horizontally, which in turn drives the radar scanning head 16 to rotate horizontally via the lower mounting plate 12 and mounting base 15. Motor 3 14 drives the mounting base 15 to rotate the radar scanning head 16 vertically, allowing for multi-angle and multi-directional scanning operations without changing the UAV's flight direction.

[0034] The side of the assembly plate 5 has a groove, and a spring 17 is fixedly installed on the inner wall of the groove. A locking plate 19 is fixedly installed at the end of the spring 17. The side of the assembly base 4 has a locking hole for the locking plate 19 to be inserted. By using the groove in conjunction with the elasticity of the spring 17 and the locking plate 19, the locking plate 19 can be inserted into or released from the locking hole to achieve convenient locking and unlocking between the assembly base 4 and the assembly plate 5. The structure is simple and the operation is convenient.

[0035] The inner wall of the spring 17 is provided with a telescopic rod 18. The two ends of the telescopic rod 18 are fixedly connected to the inner wall of the groove and the side of the clamping plate 19, respectively. The telescopic rod 18 can support and guide the movement of the clamping plate 19, improve the movement stability, prevent shaking, and ensure good assembly stability between the assembly base 4 and the assembly plate 5.

[0036] The side of the card plate 19 has an inclined surface. By setting the inclined surface, when the assembly plate 5 is inserted into the assembly slot on the assembly base 4, the card plate 19 will move into the groove by itself due to the existence of the inclined surface, which improves the convenience of assembly operation.

[0037] Several guide rods 20 are fixedly installed on the inner wall of the sliding groove of the protective cover 1. The sliding plate 7 is slidably installed on the outer surface of several guide rods 20 at the same position. The guide rods 20 can support and guide the sliding plate 7 during the up and down sliding process, improve the stability of the movement, and prevent shaking.

[0038] A support shaft 21 is fixedly installed at the end of the threaded rod 9. The support shaft 21 is rotatably installed on the inner wall of the sliding groove at the same position. The support shaft 21 can provide stable support for the rotation process of the threaded rod 9 and prevent the end of the threaded rod 9 from shaking during rotation.

[0039] The upper surface of the upper mounting plate 11 is equipped with several arc-shaped sliders 22 in a circular array. The lower surface of the upper mounting plate 6 is provided with an annular groove. The arc-shaped sliders 22 are slidably installed on the inner wall of the annular groove. The cross-section of the arc-shaped sliders 22 and the cross-section of the annular groove are both trapezoidal. By using the arc-shaped sliders 22 to slide in the annular groove, the stable rotation of the upper mounting plate 11 can be ensured, and the stability can be improved. By setting the arc-shaped sliders 22 with trapezoidal cross-sections and the annular groove, the phenomenon of up and down movement during the rotation of the upper mounting plate 11 can be avoided.

[0040] A contact plate 24 is fixedly installed on the outer surface of the rotating shaft 13, and a mounting ring 23 is fixedly installed on the lower surface of the upper mounting plate 11. Two contact switches 25 are fixedly installed on the inner wall of the mounting ring 23. The contact switches 25 are used in conjunction with the contact plate 24. The contact switches 25 are electrically connected to the motor 14 using the contact plate 24 and the mounting ring 23. When the rotating shaft 13 rotates, it drives the contact plate 24 to rotate synchronously. When the contact plate 24 touches the contact switch 25 on one side, the contact switch 25 controls the motor 14 to reverse, realizing repeated oscillation within an arc range to achieve scanning within a certain range.

[0041] In use, the semi-circular fixing ring 2 is placed on the outside of the UAV leg bracket and fixed with the fixing bolts 3. Then, the assembly plate 5 is inserted into the assembly slot on the assembly base 4. Due to the inclined surface of the clamping plate 19, the clamping plate 19 will compress the spring 17 and deform when the assembly plate 5 is inserted into the assembly slot, and enter the groove. When the assembly plate 5 is fully inserted into the assembly slot, the elastic force of the spring 17 will push the clamping plate 19 into the locking hole, completing the assembly and locking of the assembly base 4 and the assembly plate 5, realizing the installation of the protective cover 1. Then, the UAV is started and flies in the air. The motor 8 drives the threaded rod 9 to rotate, which in turn drives the upper mounting plate 11 to move downward. Thus, through the upper mounting plate 11, the lower mounting plate 12 and the mounting base 15, the radar scanning head 16 moves downward out of the protective cover 1. Then, the motor 8 is stopped and the radar scanning head 16 is started to perform radar scanning operations. Motor 2 10 drives the upper mounting plate 11 to rotate horizontally, which in turn drives the radar scanning head 16 to rotate horizontally through the lower mounting plate 12 and mounting base 15. Motor 3 14 drives the mounting base 15 to drive the radar scanning head 16 to rotate vertically. During the rotation of the rotating shaft 13 driven by motor 3 14, the contact plate 24 moves synchronously. When the contact plate 24 rotates to touch the contact switch 25 on one side, the contact switch 25 controls motor 3 14 to reverse. The two contact switches 25 work together with the contact plate 24 to make motor 3 14 continuously rotate forward and backward, so that scanning operations can be carried out from multiple angles and directions without changing the flight direction of the UAV. After the monitoring is completed, control motor 1 8 to start and retract the radar scanning head 16 into the protective cover 1 to avoid the radar scanning head 16 being external and affecting the take-off and landing process of the UAV.
