Description

Technical Field

[0001] This invention relates to an antenna, specifically a foldable array cage antenna and a communication vehicle. Background Technology

[0002] Cage antennas typically have directivity and a wide bandwidth, and are mainly used for broadband low-frequency communication. They are widely used in communication fields such as UHF (Ultra High Frequency) and VHF (Very High Frequency). Cage antennas are generally used for high-reliability long-distance low-speed communication.

[0003] Existing cage antennas are relatively large. When used for directional communication, their signal transmission direction is fixed after installation. Changing the direction requires a bulky and complex structure. Moreover, to achieve higher gain, the antennas need to be arranged in an array. Since cage antennas are already large, arrays make them even larger, leading to difficulties in installation and relocation, as well as the inability to dynamically adjust the signal transmission direction. Summary of the Invention

The lower end of the first antenna slide 75 is hinged to the second antenna slide 78 via a long rod 710, which is used to pull the second antenna slide 78 during the deployment process so that both of them approach the Z-direction extension rod 63 at the same time; each first antenna slide 75 is hinged to the second Z-direction slide 71 via a first antenna slide drive rod 76; each Y-direction cage antenna extension rod 77 and the Z-direction extension rod 63 are hinged to the cage antenna support rod 73; the cage antenna rods 79 are divided into two groups, each group having eight rods, one end of each group of cage antenna rods 79 is hinged to one end of the antenna support 74, and the other end is hinged to the end of the second antenna slide 78;

[0074] Each cage antenna mast 79 is composed of a first section, a second section, and a third section that are hinged in sequence, wherein the second sections of all cage antenna masts 79 are parallel to each other; before the drive motor 32 rotates, the Y-direction cage antenna extension rod 77, the first section, the second section, and the third section of each cage antenna mast 79 are all in contact with the Z-direction extension rod 63;

[0075] When the drive motor 32 rotates, the first antenna sliding sleeve drive rod 76, the second Z-axis sliding sleeve 71, and the first antenna sliding sleeve 75 on each side form a planar triangular structure; the Y-axis cage antenna extension rod 77 and the cage antenna support rod 73 on each side form a planar triangular structure with the Z-axis extension rod 63; the second section of each cage antenna rod 79 is parallel to the Y-axis cage antenna extension rod 77 on the corresponding side, the first and third sections of each cage antenna rod 79 are at obtuse angles to the second section, and the figure formed by connecting the midpoints of the second sections of all cage antenna rods 79 on each side is a regular octagon.

[0076] Also see Figures 4-6 This invention also provides a communication vehicle, including a front end and a frame 1, and the aforementioned foldable array cage antenna mounted on the frame 1; the lower end of the lifting rod 2 in the foldable array cage antenna is fixedly connected to the frame 1. The communication vehicle is easy to move.

[0077] The specific working process of this embodiment is as follows:

[0078] First, the communication vehicle drives to the preset location, the lifting rod 2 rises, and the upper surface of the antenna support 31 tilts to a preset angle. Then, the antenna assembly 9 begins to unfold. The drive motor 32 in the power unit 3 on the antenna support 31 uses the electrical energy provided by the communication vehicle to directly drive the drive gear 34 to rotate. The drive gear 34 drives the driven gear 35 to rotate. When the drive gear 34 and the driven gear 35 rotate, they drive the X-direction extension rods 42 on both sides to unfold horizontally. At the same time, the X-direction support rod 44 drives the X-direction sliding sleeve 43 to move along the X-direction extension rod 42 towards the drive motor 32.

[0079] When the X-axis sliding sleeve 43 moves, it sequentially pulls the Y-axis driving rod 53 and the Y-axis extending rod 54. At this time, the first Y-axis sliding sleeve 55, which is sleeved on the Y-axis extending rod 54, rotates under the drive of the Y-axis support rod 56, driving the Y-axis extending rod 54 to unfold in a direction perpendicular to the X-axis extending rod 42.

[0080] During the unfolding of the Y-direction extension rod 54, the first Y-direction sliding sleeve 55 or the second Y-direction sliding sleeve 84 fitted on it moves away from the X-direction extension rod 42, respectively driving the ground antenna support rod 87 and the fourth Y-direction rod 86 to push all the ground antenna rods 89 to unfold in a direction perpendicular to the Y-direction extension rod 54. At the same time, the Z-direction extension rod 63 also unfolds in a direction perpendicular to both the X-direction extension rod 42 and the Y-direction extension rod 54 due to the pull of the ground antenna connecting rod 810. The second Z-direction sliding sleeve 71 fitted on it slides away from the Y-direction extension rod 54. Through the cage antenna support rod 73 and the first antenna sliding sleeve drive rod 76, while unfolding the Y-direction cage antenna extension rod 77, the first antenna sliding sleeve 75 and the second antenna sliding sleeve 78 are pulled in sequence to slide towards the Z-direction extension rod 63 (the first antenna sliding sleeve 75 and the second antenna sliding sleeve 78 are linked by the long rod 710). At the same time, the cage antenna rod 79 bends into three sections (first section, second section, and third section), and the unfolding is completed.
