Description

Technical Field

[0001] This utility model belongs to the field of radar antenna technology and relates to a multi-angle adjustable antenna for radar. Background Technology

[0002] The main drawbacks of existing radar antennas in terms of their inability to be multi-angle adjustable lie in their coverage and flexibility. Since fixed-angle antennas can only cover a specific area, this limits the monitoring capabilities of radar systems, especially when monitoring multiple directions or wide areas is required. Fixed-angle radar antennas may fail to continuously track fast-moving targets, leading to data loss or inaccuracies. These shortcomings stem from the physical structure and design of the antennas, which are designed to operate at specific, typically single azimuth and elevation angles to optimize signal transmission and reception in a particular direction. Conventional solutions include using multiple fixed-angle radar antennas to cover different areas or using mechanically scanned antennas, which change the antenna's pointing direction through physical rotation. However, these methods are costly and complex. While mechanically scanned antennas offer some flexibility, their moving parts have insufficient torque, are prone to wear, and have high maintenance costs. Therefore, there is an urgent need for a multi-angle adjustable radar antenna to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-angle adjustable antenna for radar, thereby solving the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a multi-angle adjustable radar antenna, including: a top cover and a lower protective shell, wherein the top cover has three sets of fixing holes for connecting and fixing the top cover, and the three sets of fixing holes are evenly distributed at equal angles inside the top cover; and the lower end of the top cover has a radar antenna body for signal release.

[0005] The radar antenna body includes an antenna body, radar feed lines, a rotating mount, and an internal transmitting network. The radar antenna body has a set of antenna bodies for signal release in the middle. The front side of the antenna body has two sets of radar feed lines for transmitting, controlling, and distributing radio frequency electromagnetic signal energy. Each set of radar feed lines is distributed in a rectangular structure.

[0006] In a preferred embodiment, the two sets of radar feed lines are arranged side by side, and a set of support seats is provided on the outer side of the rear end of the antenna body for supporting it. The lower end of the support seat is provided with a set of inner fitting grooves for fitting and connecting with the rotating mount.

[0007] In a preferred embodiment, the inner fitting groove is provided with a set of rotating seats for active rotation, and several sets of insert strips for corresponding fitting are evenly distributed on the outer side of the rotating seats, and the several sets of insert strips are correspondingly fitted into the inner fitting groove.

[0008] In a preferred embodiment, the lower end of the rotating mount is provided with a set of gears for supporting it, and the rotating mount is located at the upper end of the middle position of the gears. The outer side of the gears is provided with teeth for meshing with the power gear. When the operator needs to adjust the orientation angle of the antenna body, the operator first starts the motor, which drives the power gear to rotate. The rotation of the power gear drives the gears to rotate. During the rotation of the gears, the rotating mount rotates, and at the same time, the rotating mount drives the support base and the antenna body to adjust the angle. The radar signal is then released through the internal transmission network, radar feed line and antenna body.

[0009] In a preferred embodiment, a set of power gears for providing rotational power to the gear disk is provided on the right side of the gear disk, and the inner diameter of the power gear in top view is one-sixth of the inner diameter of the gear disk cross-section.

[0010] In a preferred embodiment, the lower end of the power gear is provided with a set of motors for providing power to it, and the center of the antenna body is provided with a set of internal transmitting nets for releasing electromagnetic signals. Since the inner diameter of the power gear's top-view cross-section is one-sixth the length of the inner diameter of the gear disk's cross-section, when the motor rotates, the power gear drives the gear disk to rotate, which can increase the rotational torque of the gear disk, so as to drive the heavy antenna body to adjust the rotation angle. At the same time, the waterproof dust cover and waterproof gasket can protect the outside of the radar antenna body, so that external dust and air moisture can damage the radar antenna body.

[0011] In a preferred embodiment, the outer side of the radar antenna body is provided with a set of waterproof dust covers for dust and water protection, the lower end of the waterproof dust covers is provided with a set of waterproof gaskets for sealing connection with the base, and the lower end of the waterproof gaskets is provided with a set of bases for supporting it.

[0012] In a preferred embodiment, the lower end of the base is provided with a set of lower support frames for supporting its load, and a set of lower protective shells for wrapping the outside of the equipment cavity is provided in the middle of the lower support frames. The lower protective shells are sealed to the inside of the lower support frames.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the staff needs to adjust the orientation angle of the antenna body, the staff first starts the motor, which drives the power gear to rotate. The rotation of the power gear drives the gear disk to rotate. During the rotation of the gear disk, the rotating mount rotates. At the same time, the rotating mount drives the support base and the antenna body to adjust the angle, and releases the radar signal through the internal transmitting network, radar feed line and antenna body.

[0014] Since the inner diameter of the top-view cross-section of the power gear is one-sixth the length of the inner diameter of the toothed disc cross-section, when the motor rotates, the power gear drives the toothed disc to rotate, which can increase the rotation torque of the toothed disc, so as to drive the heavy antenna body to adjust the rotation angle. At the same time, the waterproof dust cover and waterproof gasket can protect the outside of the radar antenna body, so that external dust and air moisture can damage the radar antenna body.

At the same time, the waterproof dust cover 120 and the waterproof gasket 130 can protect the outside of the radar antenna body, so that external dust and air moisture can damage the radar antenna body.
