Description

Technical Field

[0001] This application relates to the field of antenna technology, specifically to a flexible patch antenna protection device and a flexible patch antenna having the same. Background Technology

[0002] Flexible patch antennas are a more flexible form of patch antennas. Their core structure inherits the traditional three-layer architecture of "metal-dielectric-metal," but utilizes flexible materials to achieve bendability and stretchability. A typical structure includes a radiating patch, a flexible dielectric layer, a ground plane, and a protective layer. Flexible patch antennas connect to the feed line via soldering or coaxial connectors. However, due to the inherently low structural strength of flexible patch antennas, the following problems can easily occur when the feed line is dragged: 1. The connection between the feed line and the patch antenna is broken, or the connection is stretched and bulges, causing the patch antenna to deform. 2. The power supply connection cable itself is broken.

[0003] Therefore, it is necessary to design a protective device that can effectively protect the flexible patch antenna. Summary of the Invention

[0004] A flexible patch antenna protection device for protecting a flexible patch antenna, comprising a mounting base, a clamping assembly, an adjustment device, and a holding device; The mounting base is positioned above the flexible patch antenna. The mounting base includes a main base, a base chamber, and side bases. The base chamber includes a rear circular hole behind the main base, a central fine hole at the front end of the rear circular hole, and a front circular hole at the front end of the central fine hole. The inner wall of the central fine hole has radially distributed slots circumferentially. The inner wall of the front circular hole has spacer rings. The front end of the main base also has a front circular tube, and the front end of the front circular tube has a front circular ring. The front circular ring has circumferentially distributed through holes. The side bases are located on the outer wall of the main base. Each side base corresponds to one of the radial slots. Each side base includes a side end block, a side inner cavity located within the side end block and communicating with the radial slots, and a perforated baffle located within the side inner cavity. The main base includes a circular portion at the top and connecting portions on both sides below the circular portion. A lower stop ring is also provided behind the inner wall of the rear circular hole.

[0005] An adjustment device, located at the front end of the mounting base, is used to drive the clamping assembly to move radially inward. The adjustment device includes a rotating assembly and a telescopic assembly. The rotating assembly includes a rotatable internally threaded tube inside the front circular tube, a front torsion ring at the front end of the internally threaded tube, upper locking teeth evenly distributed circumferentially at the rear end of the front torsion ring, and a rotating convex ring formed on the outer wall of the internally threaded tube and rotatably engaged with the portion of the front circular hole located in front of the spacer ring. The telescopic assembly includes an externally threaded tube meshing inside the internally threaded tube, a telescopic front ring located behind the externally threaded tube, and telescopic branch rods evenly distributed circumferentially behind the telescopic front ring and corresponding to radial slots one by one. Active inclined blocks are evenly distributed on the inner side of the telescopic branch rods, and a telescopic rear ring is provided at the rear end of the telescopic branch rods. A clamping assembly is disposed within the mounting base; the clamping assembly corresponds one-to-one with the radial slots, and the clamping assembly includes a clamping slider that is slidably disposed radially within the radial slot, a clamping through hole disposed within the clamping slider for accommodating the telescopic branch rod, a driven inclined block disposed on the inner wall of the clamping through hole and corresponding one-to-one with the active inclined block, a clamping insert disposed on the side of the clamping through hole and inserted into the side cavity, an insert inner hole disposed within the clamping insert for accommodating the insert with a perforated baffle, and a spring spindle disposed within the insert inner hole and inserted into the round hole of the insert with the perforated insert. The spring spindle is also provided with a clamping compression spring for driving the clamping assembly to move outward. The retaining device includes a sliding locking ring sleeved on the outer wall of the internally threaded tube, lower locking teeth evenly distributed circumferentially on the front end face of the sliding locking ring and cooperating with the upper locking teeth, a perforated longitudinal rod evenly distributed circumferentially on the rear end face of the sliding locking ring and passing through the through hole on the ring, a driven threaded ring disposed at the rear end of the perforated longitudinal rod, a driving threaded tube screwed to the outer wall of the driven threaded ring, a tube rear end ring disposed at the rear end of the driving threaded tube, and a rear rotating tube disposed behind the tube rear end ring. A torsion spring that drives the rotation of the rear rotating tube is also wound around it.

[0006] This case also discloses a flexible patch antenna, including an antenna body, a feed connection line connected to the antenna body, and a reinforcing plate disposed on the upper surface of the antenna body, wherein the aforementioned flexible patch antenna protection device is disposed on the reinforcing plate.

[0007] The power supply connection line is fixed to the antenna body by welding or by using a coaxial connector.

[0008] The technical solution of the present invention has the following technical effects: The flexible patch antenna protection device described in this case is installed on the reinforcing plate of the flexible patch antenna to effectively clamp and fix the feed connection line, avoiding breakage of the feed connection line caused by sudden dragging.

[0009] The flexible patch antenna protection device described in this case is simple to operate. It only requires rotating the rotating component to drive the telescopic component downward, which in turn drives the clamping component to move radially inward to clamp and fix the feed connection line.

[0010] The flexible patch antenna protection device described in this case, when not in use, can effectively lock the rotational degree of freedom of the rotating component, thereby preventing the telescopic component from moving downward and the clamping component from moving inward, so that the gap between the clamping components remains large enough to facilitate the installation of the feed connection line.

S2, Unlock adjustment device 2: Rotating the active threaded tube 45, the rear end ring 46, and the rear rotating tube 47 causes them to rotate against the resistance of the torsion spring 48. The active threaded tube 45 drives the driven threaded ring 44, the perforated longitudinal rod 43, the sliding locking ring 41, and the lower locking tooth 42 to move downward. The lower locking tooth 42 disengages from the upper locking tooth 213, and the rotational degree of freedom of the rotating component 21 and the movement degree of freedom of the telescopic component 22 are unlocked. Rotating the rotating component 21 causes the internal threaded tube 211 to act on the external threaded tube 221, thereby driving the telescopic component 22 to move downward. The active inclined block 224 acts on the driven inclined block 33, thereby driving the clamping assembly 3 to move inward against the damping of the clamping spring 37, and multiple clamping sliders 31 clamp and fix the power supply connection line 92.
