Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) detection radar, and in particular to an angle adjustment mechanism for UAV detection radar. Background Technology

[0002] Drone detection radar is an electronic device specifically designed to detect and track drones. Its core function is to identify drone targets flying at low or ultra-low altitudes and output key information such as their distance, speed, and azimuth to provide support for countermeasures or control.

[0003] However, traditional drone detection radars have limited tilt angles, resulting in significant blind spots and an inability to comprehensively monitor the surrounding environment. This makes them unsuitable for timely detection when drones attack from behind. Furthermore, traditional drone detection radars cannot quickly adjust to the required angle, making them ineffective in handling complex and ever-changing situations.

[0004] Therefore, this utility model proposes an angle adjustment mechanism for UAV detection radar. Utility Model Content

The tilting assembly includes housings fixed to both sides of the mounting frame; a rotating rod is rotatably connected between the two housings; the rotating rod is fixed to the lower end of the radar; one end of the rotating rod is connected to a gear; a slide rail is fixed to the bottom of one housing; a rack is slidably connected to the slide rail; the rack meshes with the gear. The support assembly, located between the radar and the tilting assembly, reinforces the radar. The fuselage is rotatably mounted at the lower end of the mounting frame; a motor is located inside the fuselage; the drive end of the motor is connected to the lower end of the mounting frame. The support assembly, located at the lower end of the fuselage, provides support for the radar.

[0008] Preferably, a cylinder is provided on one side of the slide rail; a connecting block is connected to the telescopic end of the cylinder; the connecting block is fixedly connected to the rack.

[0009] Preferably, a sleeve is fixedly provided at the lower end of the radar; the sleeve is fixedly sleeved on the outside of the rotating rod; a bracket is fixedly provided at the upper end of the mounting bracket; a fitting groove is opened at the upper end of the bracket; the sleeve is fitted and disposed in the fitting groove.

[0010] Preferably, multiple balls are evenly hinged in the fitting groove; all the balls abut against the sleeve.

[0011] Preferably, the support assembly includes a fixed seat that is fixedly mounted on the upper end of each of the two housings; a connecting shaft 1 is fixedly mounted on the side wall of the fixed seat; a connecting rod is provided at the other end of the connecting shaft 1; a slot is provided at the lower end of the connecting rod, and the connecting rod is rotatably connected to the connecting shaft 1 through the slot; a connecting shaft 2 is provided at the upper end of the connecting rod; a fixed frame is fixedly mounted between the two connecting shafts 2; and the fixed frame is fixedly connected to the radar.

[0013] Preferably, multiple protrusions are evenly provided on the side wall of the connecting shaft; multiple grooves are provided on the wall of the slot at the lower end of the connecting rod; the multiple grooves and the multiple protrusions are engaged and locked together.

[0014] Preferably, the support assembly includes multiple legs rotatably disposed at the lower end of the body; the multiple legs are arranged in a circular array around the body.

[0016] Preferably, the lower ends of the multiple support legs are rotatably equipped with foot pads.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] (1) The UAV detection radar uses an angle adjustment mechanism, including housings fixedly mounted on both sides of the mounting frame; a rotating rod is rotatably connected between the two housings; the rotating rod is fixedly mounted at the lower end of the radar; a gear is connected to one end of the rotating rod; a slide rail is fixedly mounted at the bottom of one housing; a rack is slidably connected to the slide rail; the rack is meshed with the gear. A cylinder is activated via a remote control terminal, causing the rack to slide along the slide rail, thereby rotating the gear and the rotating rod, which in turn causes the radar to flip. Compared to traditional UAV detection radars, the flipping component further expands the radar's flipping angle range. On the one hand, it allows the radar to cover a wide area from front to back, forming an all-around detection capability. On the other hand, facing dynamic threats, such as rapidly changing UAV swarms, the flipping component can adjust the detection direction in real time, improving response flexibility.

[0019] (2) The angle adjustment mechanism for the UAV detection radar includes fixed seats respectively fixedly mounted on the upper ends of two housings; a connecting shaft one is fixedly mounted on the side wall of the fixed seat; a connecting rod is provided at the other end of the connecting shaft one; a slot is opened at the lower end of the connecting rod, and the connecting rod is rotatably connected to the connecting shaft one through the slot; a connecting shaft two is provided at the upper end of the connecting rod; a fixed frame is fixedly mounted between the two connecting shaft twos; the fixed frame is fixedly connected to the radar. When the radar flips, the connecting shaft two and the fixed frame will drive the connecting rod to rotate with the radar, and then the protrusion and the groove will engage to position the connecting rod, thereby providing support to the radar in the opposite direction. This avoids insufficient support for the radar from a single point connection, which could cause the radar to shake or tip over due to the shift of the center of gravity when flipping.

[0020] (3) The UAV detection radar uses an angle adjustment mechanism, including multiple legs rotatably mounted on the lower part of the fuselage; the multiple legs are arranged in a ring array around the fuselage. By opening the multiple legs outward and supporting them on the ground, the device can be quickly erected. By distributing the force among the multiple legs, stability is enhanced, effectively reducing the shaking of the radar caused by uneven ground or vibration, ensuring that the radar can work stably in complex terrains such as mountains and wilderness. Furthermore, the multiple legs can be retracted, facilitating movement and deployment, making it convenient to transport the device to different locations and quickly set it up for use.

[0028] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0029] like Figure 1-5 As shown in the figure, an angle adjustment mechanism for a UAV detection radar provided in this embodiment of the present invention includes a mounting frame 1, a radar 4, a flipping assembly 5, a support assembly 6, a body 2, and a support assembly 3. The radar 4 is mounted above the mounting frame 1. The flipping assembly 5 is positioned between the mounting frame 1 and the radar 4, and is used to drive the radar 4 to flip. The flipping assembly 5 includes housings 51 fixedly mounted on both sides of the mounting frame 1; a rotating rod 52 is rotatably connected between the two housings 51; the rotating rod 52 is fixedly mounted at the lower end of the radar 4; one end of the rotating rod 52 is connected to a gear 53; a slide rail 54 is fixedly mounted at the bottom end of one housing 51; a rack 55 is slidably connected to the slide rail 54; the rack 55 meshes with the gear 53. The support assembly 6 is positioned between the radar 4 and the flipping assembly 5, and is used to reinforce the radar 4. The body 2 is rotatably mounted at the lower end of the mounting frame 1; a motor 21 is installed inside the body 2; the drive end of the motor 21 is connected to the lower end of the mounting frame 1. By starting the motor 21, the radar 4 can be rotated, expanding the detection range of the radar 4. Support component 3 is located at the lower end of the fuselage 2 and is used to support radar 4.

[0030] To further explain, a cylinder 56 is provided on one side of the slide rail 54; a connecting block 57 is connected to the telescopic end of the cylinder 56; the connecting block 57 is fixedly connected to the rack 55. By activating the cylinder 56, the rack 55 slides along the slide rail 54, thereby driving the gear 53 and the rotating rod 52 to rotate, which in turn causes the radar 4 to flip. Compared with traditional UAV detection radars, the flipping component 5 can further expand the flipping angle range of the radar 4. On the one hand, it allows the radar 4 to cover a wide area from front to back, forming an all-round detection capability. On the other hand, in the face of dynamic threats, such as a swarm of UAVs that change direction rapidly, the flipping component 5 can adjust the detection direction in real time, improving response flexibility.

[0031] Further explanation: A sleeve is fixedly installed at the lower end of the radar 4; the sleeve is fixedly fitted onto the outside of the rotating rod 52; a bracket 58 is fixedly installed at the upper end of the mounting bracket 1; a fitting groove is opened at the upper end of the bracket 58; the sleeve is fitted into the fitting groove. Multiple balls 59 are evenly hinged within the fitting groove; all balls 59 abut against the sleeve. The bracket 58 provides some support for the radar 4 and the rotating rod 52, and the balls 59 prevent interference with the rotation of the radar 4.

[0032] Further explanation: The support assembly 6 includes fixed seats 61 respectively fixedly mounted on the upper ends of the two housings 51; a connecting shaft 62 is fixedly mounted on the side wall of the fixed seat 61; a connecting rod 65 is mounted on the other end of the connecting shaft 62; a slot is opened at the lower end of the connecting rod 65, and the connecting rod 65 is rotatably connected to the connecting shaft 62 through the slot; a connecting shaft 67 is mounted on the upper end of the connecting rod 65; a fixing frame 68 is fixedly mounted between the two connecting shafts 67; the fixing frame 68 is fixedly connected to the radar 4. A sliding groove 66 is opened at the upper end of the connecting rod 65; the connecting shaft 67 is slidably mounted in the sliding groove 66. Multiple protrusions 63 are evenly provided on the side wall of the connecting shaft 62; multiple grooves 64 are opened on the wall of the slot at the lower end of the connecting rod 65; the multiple grooves 64 and the multiple protrusions 63 engage and lock together. The support assembly 6 can further support the radar 4, avoiding insufficient support for the radar 4 from a single point connection, which could cause the radar 4 to shake or tip over due to a shift in the center of gravity when it is flipped.

[0033] Further explanation: The support assembly 3 includes multiple legs 31 rotatably mounted on the lower end of the body 2; the multiple legs 31 are arranged in a circular array around the body 2. A sliding rod 33 is fixedly mounted on the lower end of the body 2; a sliding sleeve 34 is slidably mounted on the sliding rod 33; multiple connecting rods 35 are hinged to the side wall of the sliding sleeve 34; the multiple connecting rods 35 are arranged one-to-one with the multiple legs 31; the other end of the multiple connecting rods 35 is hinged to the corresponding leg 31. Each of the multiple legs 31 has a foot pad 32 rotatably mounted on its lower end. By distributing the force through multiple legs 31, stability can be enhanced, effectively reducing the shaking of the radar caused by uneven ground or vibration, ensuring that the radar can work stably even in complex terrain such as mountains and fields. Moreover, the multiple legs 31 can be retracted, facilitating movement and deployment, making it convenient to transport the device to different locations and quickly set it up for use.

[0034] To further explain, the angle adjustment mechanism of the UAV detection radar is controlled by a remote operating system, which includes a remote control terminal. In this application, the remote control terminal is used to control the cylinder 56 and the motor 21. It is evident that both the cylinder 56 and the motor 21 are locally equipped with signal receiving modules; these modules remotely receive signals from the remote control terminal, thereby enabling the start and stop of the cylinder 56 and the motor 21.

[0035] The working principle of this utility model is as follows: During operation, multiple support legs 31 are opened outwards, and multiple foot pads 32 are placed on the ground, allowing the device to be quickly erected. Then, the motor 21 is started via a remote control terminal to rotate the radar 4 for detecting drones. When the tilt angle of the radar 4 needs to be adjusted, the cylinder 56 is started via the remote control terminal, causing the rack 55 to slide along the slide rail 54, thereby rotating the gear 53 and the rotating rod 52, which in turn causes the radar 4 to tilt. When the radar 4 tilts, the connecting shaft 67 and the fixing frame 68 cause the connecting rod 65 to rotate with the radar 4. Subsequently, the protrusion 63 and the groove 64 engage to position the connecting rod 65, thus providing support to the radar 4 in the opposite direction.

[0036] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
