Description

TECHNICAL FIELD

[0001] The present application relates to the field of motorized anti-UAV systems, in particular to a vehicle-mounted antenna array folding and unfolding mechanism. BACKGROUND

[0002] In the field of motorized anti-UAV systems, the adjustment and storage of high-power jamming antenna arrays are of great importance. In the past, the common implementation scheme is to use a combination of a two-dimensional servo turntable and a lifting mechanism. The two-dimensional servo turntable is mainly responsible for the adjustment of the azimuth and elevation of the antenna array, achieving the adjustment of the angle of the antenna array within a certain range. The lifting mechanism is responsible for lifting the servo turntable and the antenna array, and when the antenna array is working, it lifts them to a specified height to ensure that the antenna array is in the appropriate working position, so as to achieve good signal transmission effect. In practical applications, many anti-UAV systems around military bases and important facilities use such architecture, such as defense facilities in some border control areas. This traditional architecture has met the basic functional requirements in the past, but with the development of technology and the diversification of practical application scenarios, its limitations have gradually emerged.

[0003] The traditional combination scheme of two-dimensional servo turntable and lifting mechanism uses multiple motion mechanisms to cooperatively realize lifting and azimuth, elevation adjustment. Its connection and debugging are complex, the manufacturing difficulty is great, and component failure can easily cause system failure, which takes a long time to repair and troubleshoot. In terms of use and maintenance, due to the complex structure, high requirements for personnel professional skills, tedious daily maintenance operations, difficult fault location and repair, and the need for professional equipment and technical support, the cost is high. For vehicles, the lifting mechanism has high bearing requirements, which limits the selection of vehicles, often needs to be reinforced and modified, increases the purchase and modification cost, and affects the mobility and flexibility. SUMMARY

[0004] Therefore, the present application proposes a vehicle-mounted antenna array mechanism, which is characterized by comprising a base, a turntable base, an azimuth turntable, an elevation support arm, a jamming antenna array, and a high-power transmitter. The base is suitable for being installed on the mounting surface at the tail of the vehicle. The turntable base is installed on the base and has a preset height. The side opposite to the side in contact with the mounting surface of the base extends upward to support the azimuth turntable and the elevation support arm. The azimuth turntable is installed on the turntable base and is fixedly connected with the turntable base. One end of the elevation support arm is connected with the azimuth turntable through a rotary support. The elevation support arm can be adjusted in elevation relative to the azimuth turntable and can rotate in the horizontal direction. The elevation support arm is connected with the high-power transmitter. When the elevation support arm performs the elevation and rotation actions, the vehicle-mounted antenna array mechanism adjusts the height and angle of the antenna array within a certain range.

[0005] Preferably, the rotation and elevation angle range of the elevation support arm installed on the azimuth turntable is 0-180°.

[0006] Preferably, the azimuth turntable can rotate 360°, thereby driving the support arm structure to rotate 360°.

[0007] Preferably, the vehicle-mounted antenna array mechanism flips and lifts the antenna array surface from the rear of the vehicle compartment to the top of the vehicle compartment during operation, and the pitch support arm can adjust the angle of the antenna array surface within a range of 0-90°, while adjusting the height of the antenna array surface.

[0008] Preferably, the azimuth turntable has a rotating motor and a pitch movement motor inside.

[0009] Preferably, the pitch support arm mounting surface is fixedly installed with the interference antenna array and the high-power transmitter in an eccentric mounting manner, and the interference antenna array is installed above the high-power generator.

[0010] Preferably, the vehicle-mounted antenna array mechanism is in a folded state when it is not in operation, at which time the pitch support arm is at 180°.

[0011] Preferably, the height of the eccentric mounting manner is variable, and the limit height is 95% of the total height of the antenna folding and unfolding mechanism carrier.

[0012] Preferably, the pitch mechanism of the azimuth turntable flips and lifts the antenna array surface from the rear of the vehicle compartment to the top of the vehicle compartment, and then the pitch mechanism of the azimuth turntable adjusts the azimuth angle and the pitch angle of the antenna array surface according to the target position.

[0013] Preferably, the height of the base is such that the height of the antenna folding and unfolding mechanism combined with the rear compartment of the carrier is 80-90% of the overall passing height of the carrier.

[0014] The beneficial effects of the utility model are as follows:

[0015] The lifting mechanism in the traditional scheme is cancelled, and the number of components is greatly reduced. Compared with the combination of a complex two-dimensional servo turntable and a lifting mechanism, it is more simple, reduces the difficulty of overall design and manufacturing, reduces the connection and cooperation problems between parts, and improves the stability and reliability of the system.

[0016] The design complexity of the antenna array control system is significantly reduced. During development, there is no need to consider the complex control logic and mechanical cooperation between the lifting mechanism and the two-dimensional servo turntable, which reduces a large amount of system development and debugging work, shortens the research and development cycle, and reduces the research and development cost.

[0017] Under the premise of meeting the normal passing performance of the vehicle, the antenna array can be flipped back and stored in the rear of the vehicle compartment in a non-working state, effectively reducing the height of the antenna array, so that its highest position is lower than the passing height of the vehicle, avoiding occupying too much vehicle space, improving the space utilization of the vehicle, and facilitating the vehicle to carry other equipment or perform other tasks during transportation.

[0018] By reducing the number of components and the complexity of the structure, the probability of failure is lowered. Compared with traditional solutions, the present invention has fewer mechanical parts, reducing potential failure points. At the same time, the simplified structure makes maintenance more convenient, enabling timely detection and problem solving, thereby improving the reliability of the vehicle-mounted antenna array adjustment mechanism and ensuring the stable operation of the anti-drone system.
