Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and more particularly to a portable, fast-folding antenna. Background Technology

[0002] With the development of satellite communication, antennas, as the means of transmitting and receiving signals, have become increasingly important in terms of their structure, performance, and manufacturing cost. Miniaturization and portability of antennas are particularly key areas of research.

[0003] Some foldable antennas on the market use hydraulic or motor-driven mechanisms, resulting in a large folding diameter, large antenna size and weight, and a complex structure, which is not conducive to later maintenance and makes it difficult to meet the requirements of lightweight, portable, and fast-folding antennas. Others have small size and light weight folding structures, but their folding structure has low locking accuracy, and its lifespan and reliability are low in harsh mechanical and climatic environments, making these structures unsuitable for antenna applications.

[0004] Most modern antennas are complex in structure, large in size, and heavy in weight, making them inconvenient to carry and lacking a good resonant structure. Many components are exposed outside the cavity during use, requiring multiple parts to be assembled. Initial installation and debugging takes a long time, operation is cumbersome, and use is extremely inconvenient. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a portable, quick-folding antenna that is quick and easy to fold, has a simple structure, high portability, is easy to set up, and is convenient to maintain. It can meet the requirements of small-diameter, lightweight, portable folding antennas that are easy to install, use, and maintain.

[0006] The technical solution adopted in this invention is as follows:

[0007] A portable, quick-folding antenna includes n antenna subarrays, n rotating shafts, a base, an unfolding button, and a linkage transmission mechanism. The antenna subarrays are mounted on the top and / or bottom surfaces of the base via rotating shafts and can rotate with the rotating shafts. The unfolding button is connected to the linkage transmission mechanism, which is located inside the base and connected to the rotating shafts via mechanical limiting walls and tension springs. The unfolding button, through the linkage transmission mechanism and rotating shafts, enables the n antenna subarrays to rotate and unfold to a vertical working state, and all antenna subarrays can be simultaneously folded up when any one antenna subarray is closed.

[0008] Furthermore, the linkage transmission mechanism includes a slide rod, a tension spring, a left connecting rod, a right connecting rod, a rotating disk, a left rotating disk, and a right rotating disk. The slide rod connects the unfolding button and the rotating disk. The rotating disk connects the left connecting rod, the right connecting rod, and a rotating shaft on one side. The left rotating disk connects the left rotating shaft on the other side and the left connecting rod. The right rotating disk connects the right rotating shaft on the other side and the right connecting rod. Tension springs are provided on both the left and right rotating disks.

[0009] Furthermore, one end of the slide rod is inserted into the corresponding shaft hole of the unfold button, and the other end is fixed to the rotating disk by screws. The slide rod is provided with a horizontal sliding groove, and the up and down movement of the unfold button is converted into the rotational movement of the rotating disk through the slide rod.

[0010] Furthermore, mechanical limiting arms are provided on the left and right rotating disks to limit the rotation angle of the antenna subarray. Pressing the unfold button causes the rotating disk to rotate the right rotating disk 90° clockwise and simultaneously rotate the left rotating disk 90° counterclockwise. At this time, the antenna subarray rotates 90° to achieve a vertical working state; when one antenna subarray is closed, the other antenna subarrays can be simultaneously and quickly folded together.

[0011] Furthermore, the antenna subarray includes a microstrip sheet, a threaded block, a mounting plate, an radome, and a connector, wherein the microstrip sheet is fixed to the mounting plate by the threaded block, the connector is screwed onto the bottom end of the mounting plate, and the radome is connected to the mounting plate.

[0012] Furthermore, the connector includes an SMP-J type RF coaxial connector.

[0013] Furthermore, the rotating shaft includes a rotating seat rod, a cover, and a sealing ring, wherein the cover is fixed on the rotating seat rod, the sealing ring is provided on the corresponding groove of the rotating seat rod, and the rotating seat rod is connected and fixed to the antenna subarray.

[0014] Furthermore, the antenna subarray is connected to a sum and difference converter via a cable assembly for signal input, and the sum and difference converter is connected to an RF quick-connect connector via the same cable assembly for signal output. The entire folding antenna includes RF interfaces for sum, difference, and omnidirectional channels, enabling dual-channel directional transmission and reception for sum and difference, as well as omnidirectional transmission and reception.

[0015] Furthermore, it also includes a pickup truck rail, which is fixed to the side of the base to enable rapid installation of the antenna subarray.

[0016] Furthermore, it also includes a front cover plate, a rear cover plate, and a small cover plate. The front cover plate is located in front of the base, the rear cover plate is located behind the base, and the small cover plate is located above both ends of the base. The front cover plate, rear cover plate, and small cover plate are connected to the base to achieve sealing protection.

[0017] The beneficial effects of this invention are as follows:

[0018] (1) This invention uses a linkage transmission mechanism to achieve linkage of multiple antenna arrays. The linkage transmission mechanism is equipped with mechanical limit walls and tension springs. With one press of the unfold button, multiple antenna arrays can automatically rotate 90° to achieve a vertical working state, without the need to manually swing the antennas, and have a good inherent state. When one of the subarrays is closed, multiple subarrays can be closed simultaneously and quickly.

[0019] (2) When communication is not required, the portable quick-folding antenna of the present invention can be folded into the base, which occupies little space; the base, cover plate, antenna cover and other components are made of non-metallic materials, and the mounting surface of the antenna array is plated with metal to ensure conductivity. The entire antenna weighs only 600g, which is lightweight and small in size; all cover plates and antenna covers are sealed with silicone rubber to ensure overall sealing and adapt to various harsh environments.

[0020] (3) The portable quick-folding antenna of the present invention has a pickup rail installed on the side of the base, which can realize the antenna quick fixation, with good human-machine efficiency and convenient use; the antenna is easy to set up, wear and fold up, and can be completed independently by a single person.
