A security radar for drone take-off and landing

Abstract

This utility model discloses a security radar for UAV take-off and landing, relating to the field of UAV radar. It includes a mounting base with a main connecting arm rotatably connected to its bottom. A first rotating seat is rotatably connected to the main connecting arm, and two secondary connecting arms are connected to the outer side of the first rotating seat. A radar body is rotatably connected between the two secondary connecting arms. A first elastic abutment pad is telescopically connected to the top of the inner part of the main connecting arm. When the radar body completes rotation, a first and second electric push rod can extend, causing the first and second elastic abutment pads to abut against the outer side of the radar body, forming a fixed abutment. This establishes a connection between the main connecting arm and the radar body, preventing the radar body from swaying and rotating due to wind and flight influences, thus improving stability. When the radar body rotates, the first and second electric push rods retract to avoid affecting the rotation.

Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) radar, and in particular to a security radar applied to the take-off and landing of UAVs. Background Technology

[0002] With the rapid development of drone technology, its applications in logistics, power line inspection, and emergency rescue are becoming increasingly widespread. The safety of drones during takeoff and landing has become a core concern for the industry. Currently, security in drone takeoff and landing areas mainly relies on fixed radar monitoring, visual recognition, or manual surveillance.

[0003] For example, a patent entitled "A Radar Device for Unmanned Aerial Vehicles" (patent application number: CN202321151972.1) discloses a radar device for unmanned aerial vehicles. The radar measuring mechanism is mounted on a gimbal and can rotate at any angle while keeping the lens stable, which is convenient for directional and angle measurement of the flow velocity of objects at corresponding positions. It can achieve a stable measurement attitude and realize roll, pitch and 360° horizontal rotation. However, after the radar measuring mechanism completes a rotation of an angle, there is a certain space between the radar measuring mechanism and the connecting arm. The radar measuring mechanism is only connected by the auxiliary arms on both sides. When the wind force is large, it is easy to affect the stability of the radar measuring mechanism.

[0004] Therefore, it is necessary to propose a security radar for UAV take-off and landing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a security radar for UAV take-off and landing, in order to solve the problem that after the radar measuring mechanism completes a rotation of an angle, there is a certain space between the radar measuring mechanism and the connecting arm, and the radar measuring mechanism is only connected by the auxiliary arms on both sides. When the wind force is strong, the stability of the radar measuring mechanism is easily affected.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a security radar for take-off and landing of unmanned aerial vehicles, including a mounting base, a main connecting arm rotatably connected to the bottom end of the mounting base, a first rotating seat rotatably connected to the main connecting arm, two auxiliary connecting arms connected to the outer side of the first rotating seat, and a radar body rotatably connected between the two auxiliary connecting arms.

[0007] The main connecting arm has a first elastic abutment pad telescopically connected to its inner top end, and the first rotating seat has a second elastic abutment pad telescopically connected to the side of the radar body near the radar body.

[0008] A damping telescopic rod is fixed to the bottom end of the main connecting arm, and a supporting base plate is fixedly connected to the bottom end of the damping telescopic rod. The supporting base plate is located below the radar body.

[0009] Preferably, the main connecting arm is L-shaped, a first electric push rod is provided between the main connecting arm and the first elastic abutment pad, and a second electric push rod is provided between the first rotating seat and the second elastic abutment pad.

[0010] Preferably, a first motor is provided at the top of the mounting base, the drive shaft of the first motor is connected to the main connecting arm, a second motor is provided inside the auxiliary connecting arm, one end of the second motor is connected to a second rotating seat, the second rotating seat is fixedly connected to the side of the radar body, and a third motor is provided at the bottom of the main connecting arm, the drive shaft of the third motor is connected to the first rotating seat.

[0011] Preferably, the radar body is internally provided with a signal transmitting module, a signal receiving module, a target detection and identification unit, and a data processing and control module. The signal transmitting module and the signal receiving module are connected by signals, and the data processing and control module is connected to the target detection and identification unit.

[0012] According to the claim, a security radar for drone take-off and landing is characterized in that: the mounting base has a mounting hole, and the mounting hole is connected to the drone by a fixing bolt.

[0013] Preferably, the radar body is provided with an outer shell, and the outer shell has heat dissipation grooves.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. The main connecting arm is designed with an L-shaped hollow structure. The length of the horizontal section is adapted to the detection radius from the edge to the center of the UAV take-off and landing platform. The end of the vertical section is connected to the support base plate through a damping telescopic rod. This design ensures structural strength while reducing overall weight through the hollow design. When the UAV descends, the support base plate will make contact with the ground or obstacles first, avoiding direct collision between the ground or obstacles and the radar body, which could cause damage. In the event of a collision, the damping telescopic rod can act as a buffer.

[0016] 2. In the actual operation of this utility model, after the radar body has completed its rotation, the first electric push rod and the second electric push rod can be extended, so that the first elastic abutment pad and the second elastic abutment pad abut against the outside of the radar body to form abutment fixation, thereby forming a connection between the main connecting arm and the radar body. This avoids the radar body from shaking and rotating due to wind and flight influences, thus improving stability. When the radar body rotates, the first electric push rod and the second electric push rod return to avoid affecting the rotation.

[0017] 3. Driven by the first motor, the second motor, and the third motor, the main connecting arm and the auxiliary connecting arm can rotate, thereby enabling the radar body to rotate and detect in all directions, eliminating the detection blind spots of traditional fixed radar, and effectively identifying obstacles such as intruding birds and drones with different frequencies.

[0022] This utility model provides, for example Figures 1-3 The security radar shown includes a mounting base 1, a main connecting arm 2 rotatably connected to the bottom of the mounting base 1, a first rotating seat 3 rotatably connected to the main connecting arm 2, two auxiliary connecting arms 4 connected to the outside of the first rotating seat 3, and a radar body 6 rotatably connected between the two auxiliary connecting arms 4.

[0023] Mounting base 1 has mounting holes, which are connected to the UAV by fixing bolts, facilitating installation and subsequent disassembly. The radar body 6 has an outer shell with heat dissipation grooves to improve heat dissipation efficiency.

[0024] A first motor is installed inside the mounting base 1, and the drive shaft of the first motor is connected to the main connecting arm 2. A second motor is installed inside the auxiliary connecting arm 4, and one end of the second motor is connected to a second rotating seat 5, which is fixedly connected to the side of the radar body 6. A third motor is installed at the bottom inside the main connecting arm 2, and the drive shaft of the third motor is connected to the first rotating seat 3.

[0025] A damping telescopic rod 7 is fixed to the bottom end of the main connecting arm 2, and a support base plate 8 is fixedly connected to the bottom end of the damping telescopic rod 7. The support base plate 8 is located below the radar body 6.

[0026] Driven by the first motor, the second motor, and the third motor, the main connecting arm 2 and the auxiliary connecting arm 4 can rotate, thereby enabling the radar body 6 to rotate and detect in all directions, eliminating the detection blind spots of traditional fixed radar, and effectively identifying obstacles such as intruding birds and drones operating at different frequencies.

[0027] Mounting base 1 is made of high-strength aluminum alloy casting and integrates a first motor (selected as a servo motor). Its drive shaft is rigidly connected to the main connecting arm 2 through a coupling, which can drive the main connecting arm 2 to achieve 360-degree horizontal rotation. The main connecting arm 2 is designed with an L-shaped hollow structure. The length of the horizontal section is adapted to the detection radius from the edge to the center of the UAV take-off and landing platform. The end of the vertical section is connected to the support base plate 8 through a damping telescopic rod 7. This design ensures structural strength while reducing overall weight through hollow design. When the UAV descends, the support base plate 8 will first contact the ground or an obstacle, avoiding direct collision between the ground or obstacle and the radar body 6, which could cause damage. In the event of a collision, the damping telescopic rod 7 can act as a buffer.

[0028] The main connecting arm 2 has a first elastic abutment pad 10 telescopically connected to its inner top end, and the first rotating seat 3 has a second elastic abutment pad 12 telescopically connected to the side near the radar body 6.

[0029] The main connecting arm 2 is L-shaped, and a first electric push rod 9 is provided between the main connecting arm 2 and the first elastic abutment pad 10. A second electric push rod 11 is provided between the first rotating seat 3 and the second elastic abutment pad 12.

[0030] In the actual operation of this utility model, after the radar body 6 has completed its rotation, the first electric push rod 9 and the second electric push rod 11 can be extended, so that the first elastic abutment pad 10 and the second elastic abutment pad 12 abut against the outside of the radar body 6 to form abutment fixation, thereby avoiding the shaking and rotation of the radar body 6 after rotation due to wind force and flight influence, and improving stability.

[0031] Since both the first elastic contact pad 10 and the second elastic contact pad 12 are elastic, they can be adapted to fit the shape of the outer side of the radar body 6.

[0032] The radar body 6 is equipped with a signal transmitting module for transmitting radar signals at a specific frequency, a signal receiving module, a target detection and identification unit, and a data processing and control module. The signal transmitting module and the signal receiving module are connected by signals.

[0033] The signal receiving module is used to receive radar signals reflected back by the UAV or surrounding obstacles. The target detection and identification unit analyzes and detects the position and speed of potential obstacles near the UAV during take-off and landing based on the received reflected signals. It also obtains the target's speed information by analyzing the Doppler frequency shift of the reflected signals and identifies the target's size and category using signal strength and reflected wave characteristics.

[0034] The data processing and control module is connected to the target detection and recognition unit. It processes the detected data, determines the safety of the UAV during take-off and landing based on preset safety thresholds and algorithms, and generates corresponding control commands.

[0035] The communication interface module is used to interact with the UAV control system and external monitoring equipment, transmitting the monitoring data of the security radar to the UAV control system to assist its take-off and landing decisions, while receiving control commands from the external monitoring equipment.
