[0002] A communication antenna is equipped with a feed, which serves as the primary radiator of a high-gain antenna. It converts high-frequency currents or bound electromagnetic waves into radiated electromagnetic energy. Multiple feeds can be installed on a communication antenna, each capable of receiving and transmitting signals in different frequency bands. To ensure optimal retraction and extension of a feed, it must be positioned at the antenna's center, requiring adjustment.

[0003] Currently, traditional feed switching methods can require a long time to precisely adjust the feed position to ensure optimal signal transmission, affecting the antenna system's rapid response and resulting in low feed switching efficiency. Complex feed switching mechanisms and drive systems can increase maintenance difficulty and costs, reducing overall system reliability and increasing maintenance costs. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0021] The utility model is an electric feed-changing system, which is a system with multiple feed sources and can change the position of the feed sources.

[0022] The system includes a feed source, which generally has multiple feed sources. By setting up multiple different feed sources, the antenna of the system can receive or transmit signals in different frequency bands. The feed source in this technical solution is a conventional setting, and the focus is on the feed switching structure.

[0023] The system also includes a feed-changing structure for moving and changing the position of the feed source. Figure 1 、 Figure 2 As shown, the feed structure includes a support rail 1, a ball screw 2 and a drive member 3. The support rail 1 plays a role of support and as a guide rail. The feed source 5 is slidingly set on the support rail 1, and the feed source 5 can slide on the support rail 1 to move its position. The support rails 1 are usually set in parallel with two spaced distances, and connecting beams are provided at both ends of the two support rails 1. The two support rails 1 and the two connecting beams form a support skeleton. The ball screw 2 is rotatably set on the support skeleton. One end of the ball screw 2 is rotatably connected to the connecting beam through a bearing, and the other end is dynamically connected to the drive member 3. In addition, the ball screw 2 also passes through the feed source 5, thereby forming a ball screw pair with the feed source 5. When the ball screw 2 rotates, it can drive the feed source 5 to move its position.

[0024] When the linear position of the feed source needs to be moved, the driving member 3 drives the ball screw 2 to rotate, and the ball screw 2 drives the feed source 5 to slide on the support guide rail 1.

[0025] The electric feed-changing system has a feed support rod interface 4 fixedly provided at the bottom of the support rail 1, and the feed support rod is connected via a ball screw 2, thereby realizing the installation of the system.

[0026] In this system, the driving member 3 drives the ball screw 2 to rotate. The driving member 3 can be a motor combined with a worm gear reducer. The driving member 3 includes a motor and a worm gear reducer, and the output end of the motor is connected to the input end of the worm gear reducer, and the output end of the worm gear reducer is connected to the end of the ball screw 2. The motor can realize the rotational drive of the ball screw 2 through the worm gear reducer. The electric feed adopts a combination of a ball screw, a guide rail and a feed source slider. The motor drives the worm gear reducer to drive the ball screw to rotate, thereby ensuring that the feed source can be driven to perform translational motion stably and reliably. The worm gear reducer has mechanical self-locking properties. After the feed structure stops running, it can ensure that the relative position of the feed source and the antenna is stable, which simplifies the structure and reduces costs.

[0027] Furthermore, the ball screw, drive motor, and worm gear reducer combination can be replaced with a linear motor module. This offers higher acceleration and deceleration capabilities, shortening feed switching time and improving feed position accuracy. The linear motor module's compact size and light weight can significantly reduce the burden on the antenna drive system and lower antenna drive power consumption.

[0028] The system is also provided with a position sensor. The position sensor is provided on the feed source to detect whether the position of feed sources 1, 2, 3, and 4 is at the center of the antenna and whether they have reached the predetermined position.

[0029] When in use, the driving component drives the ball screw to rotate, thereby allowing multiple feed sources to move relative to the antenna center position so that different feed sources can be relative to the center position, allowing the antenna to receive or transmit signals in different frequency bands.

[0030] In this technical solution, a plurality of feed sources 5 are usually provided, and these feed sources 5 are all provided on the support rail 1 , and these feed sources 5 are all penetrated and matched with the ball screw 2 . Figure 1 Four feed sources are provided in the system. Limiting mechanisms or limiting members are provided at both ends of the support rail 1 to prevent the feed source from exceeding a preset range and ensure the safety of the feed switching system operation.

[0031] The utility model discloses an electric feed switching system, in which multiple feed sources are slidingly arranged on a supporting guide rail. The feed sources and a ball screw form a ball screw pair. The electric drive mechanism is connected to the ball screw to realize rotational drive. The position of the feed source is automatically adjusted by electric means, so that the antenna can continuously align with the optimal signal direction, thereby improving the efficiency and stability of signal reception.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
