Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of multi-feed source vehicle antenna, concretely relates to a multi-feed source vehicle antenna system. BACKGROUND

[0002] Vehicle antennas, especially multi-feed source vehicle antennas, play a crucial role in modern communication systems. By integrating multiple feeds, multi-feed source vehicle antennas can receive and transmit signals in different directions or frequencies, thereby enhancing the flexibility and efficiency of communication systems. The feeds of multi-feed source vehicle antennas need to be replaced or maintained regularly due to long-term use or technological upgrading requirements.

[0003] There has been some research on multi-feed source vehicle antenna systems in the prior art. Referring to patent document No. 201911031258.7, an antenna feed folding mechanism is disclosed, which includes a mounting base, an antenna, and a feed support rod. The flip wings are connected to the two outer sides of the mounting base. The drive motor is connected to the flip wings. The antenna is fixedly connected to the feed connector through connecting bolts. The feed support rod is installed with a feed at the end away from the feed connector. The support frame is fixed to the bottom of the slope on the mounting base. The antenna feed folding mechanism drives the antenna to move downward through the drive motor. The feed and feed connector also move downward with the motor. When the feed rod and the support frame come into contact, the feed rod no longer moves downward. The antenna continues to move downward and the torsion spring is compressed until the antenna moves to the horizontal position. When the antenna moves upward, the feed rod automatically returns to its original angle due to the action of the torsion spring, thereby achieving automatic folding and automatic unfolding of the antenna feed.

[0004] As can be seen, when replacing the feed, the antenna needs to be folded to the horizontal position by the drive motor first, so that the feed support rod contacts and is relatively fixed with the support frame. At this time, a certain operation space is formed between the feed and the antenna main body, and the technician can safely disassemble the connecting bolts, disconnect the connection between the feed connector and the antenna, and then replace the feed. However, during the feed replacement process, the antenna needs to be in a shutdown state. The feed replacement process of the antenna feed folding mechanism is complex, and the time required for replacing the feed is long. The antenna in the shutdown state for a long time is prone to communication interruption, affecting the continuity and stability of communication, and thus affecting user experience and business operation.
