Description

Technical Field

[0001] The utility model relates to the technical field of antennas, and in particular to a conformable and coated antenna structure. Background Art

[0002] The internal structure of the patch antenna is a zigzag line, also known as a serpentine line. Because of its special zigzag structure, the surface current length can be effectively increased, and the overall length of the antenna is reduced. Therefore, it is the favorite for antenna miniaturization and has become a hot topic of research. The patch antenna uses patch technology and can be directly attached to the circuit board. It does not need to be installed independently like traditional antennas. The patch antenna has the advantages of small size, light weight, low cost, and easy integration. It has become a new choice in the field of wireless communications.

[0003] Existing patch antennas are often directly pasted on the surface of a circuit board. Although this is very convenient, the adhesion effect between the patch antenna and the circuit board may be reduced over a long period of use, resulting in a loose bond between the patch antenna and the circuit board, or even falling off the circuit board. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the patch antenna is not firmly bonded to the circuit board after long-term use, and proposes a conformable coated antenna structure.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a conformable covered antenna structure, including a circuit board, an antenna body is arranged at the top of the circuit board, a conformable film is arranged at the top of the antenna body, an adhesive layer is arranged at the bottom end of the conformable film, a waterproof layer is arranged at the top of the conformable film, four through holes are opened through the top of the conformable film, four threaded holes are opened at the top of the circuit board, and two fixing mechanisms are arranged at the top of the circuit board.

[0006] Preferably, the fixing mechanism comprises a fixing block, an outer wall of the fixing block is provided with a sliding groove, and an inner wall of the sliding groove is movably provided with a threaded screw.

[0007] Preferably, the outer wall of the threaded screw is threadedly connected with a slider, the slider is movably inserted in the inner wall of the slide groove, and a pressing plate is fixedly installed on the bottom end of the slider.

[0008] Preferably, the top end of the pressing plate is fixed with two threaded sleeves, the inner walls of the two threaded sleeves are threadedly connected with screws, and the output ends of the two screws pass through the pressing plate.

[0009] Preferably, a rotating disk is fixedly mounted on the top ends of the two screw rods, and the outer surface wall of the rotating disk is provided with anti-slip stripes.

[0010] Preferably, a rotating rod is movably inserted into the top of the fixed block, the output end of the rotating rod passes through the inner wall of the slide groove and is fixedly connected to one end of the outer wall of the threaded screw, and a rotating plate is fixedly installed on the top of the rotating rod.

[0011] Preferably, the two fixing blocks are fixedly connected to the circuit board, and the four threaded holes are matched with four screw rods respectively.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when the laminating film is pasted to the surface of the circuit board, in order to make the laminating film more firmly, the rotating plate can be rotated, and the rotating plate drives the rotating rod and the threaded screw to rotate. The threaded screw drives the slider to move downward during the rotation process, and the slider drives the pressing plate to move downward until the pressing plate squeezes the laminating film, thereby making the laminating film more firmly. When the pressing plate is tightly fitted with the laminating film, the rotating disk is rotated, and the rotating disk drives the screw to rotate inside the threaded sleeve. The screw moves downward and passes through the through hole during the rotation process, and then enters the threaded hole and is threadedly connected to the circuit board, thereby improving the stability of the pressing plate, and then improving the squeezing and fixing effect of the pressing plate on the laminating film.

[0014] 2. In the utility model, a bonding film is bonded on the top of the antenna body. The bonding film can protect the antenna body and prevent the antenna body from being damaged by the external environment, thereby increasing the service life of the antenna body. At the same time, a waterproof layer is arranged on the surface of the bonding film. The waterproof layer can prevent external moisture from passing through the bonding film and causing damage to the antenna body. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The effect achieved by the entire embodiment 1 is that when the antenna body 2 needs to be fixed, the antenna body 2 is first placed on the surface of the circuit board 1, and then the laminating film 3 is laminating on the surface of the circuit board 1. An adhesive layer 5 is provided at the bottom of the laminating film 3, and the adhesive layer 5 can bond the laminating film 3 and the circuit board 1. The laminating film 3 can protect the antenna body 2 and prevent the antenna body 2 from being damaged by the external environment, thereby improving the service life of the antenna body 2. A waterproof layer 6 is provided on the surface of the laminating film 3, and the waterproof layer 6 can prevent external moisture from passing through the laminating film 3 to damage the antenna body 2.

[0024] Embodiment 2, as Figure 1-Figure 4As shown, the fixing mechanism 7 includes a fixing block 701, the outer wall of the fixing block 701 is provided with a slide groove 702, and the inner wall of the slide groove 702 is movably inserted with a threaded screw 703. The outer wall of the threaded screw 703 is threadedly connected with a slider 704, and the slider 704 is movably inserted in the inner wall of the slide groove 702, and a pressing plate 705 is fixedly installed at the bottom end of the slider 704. The top of the pressing plate 705 is fixed with two threaded sleeves 706, and the inner walls of the two threaded sleeves 706 are both threadedly connected with screws 707, and the output ends of the two screws 707 both penetrate the pressing plate 705. The tops of the two screws 707 are fixedly installed with a rotating disk 708, and the outer wall of the rotating disk 708 is provided with anti-slip stripes. A rotating rod 709 is movably inserted at the top of the fixed block 701, and the output end of the rotating rod 709 passes through the inner wall of the slide slot 702 and is fixedly connected to one end of the outer wall of the threaded screw 703.

[0025] The effect achieved by the entire embodiment 2 is that when the bonding film 3 is pasted to the surface of the circuit board 1, in order to make the bonding film 3 more secure, the rotating plate 710 can be rotated, and the rotating plate 710 drives the rotating rod 709 and the screw rod 703 to rotate. The screw rod 703 drives the slider 704 to move downward during the rotation process, and the slider 704 drives the pressing plate 705 to move downward until the pressing plate 705 squeezes the bonding film 3, thereby making the bonding film 3 more secure.

When the laminating film 3 is pasted to the surface of the circuit board 1, in order to make the laminating film 3 more firm, the rotating plate 710 can be rotated. The rotating plate 710 drives the rotating rod 709 and the threaded screw 703 to rotate. The threaded screw 703 drives the slider 704 to move downward during the rotation. The slider 704 drives the pressing plate 705 to move downward until the pressing plate 705 squeezes the laminating film 3. This makes the laminating film 3 more secure. When the pressing plate 705 is tightly fitted with the laminating film 3, the rotating disk 708 is rotated, and the rotating disk 708 drives the screw 707 to rotate inside the threaded sleeve 706. The screw 707 moves downward and passes through the through hole 4 during the rotation, and then enters the threaded hole 8 and is threadedly connected to the circuit board 1, thereby improving the stability of the pressing plate 705, and further improving the squeezing and fixing effect of the pressing plate 705 on the laminating film 3. At the same time, the laminating film 3 can protect the antenna body 2 and prevent the antenna body 2 from being damaged by the external environment, thereby improving the service life of the antenna body 2.
