[0028] As shown in Figures 1-3 A wireless bridge built-in antenna, comprising:

[0029] The frame 1 is arranged side by side with two;

[0030] The antenna body 4 is arranged between the two frames 1, and the side edges of the antenna body 4 are detachably connected with the frames 1;

[0031] The elastic connecting piece is arranged between the two frames 1, and the two ends thereof are detachably connected with the two frames 1, respectively;

[0032] The adhesive part 101 is arranged on the bottom surface of the frame 1 in the extension direction of the frame 1.

[0033] The PCB board antenna can be used as the built-in antenna of the wireless bridge, and is used for signal transmission of the wireless bridge. In the above built-in antenna of the wireless bridge, the antenna body 4 is a PCB board, the frame 1 is arranged on the opposite side edges of the antenna body 4, the two frames 1 are connected through the elastic connecting piece, and the frame 1 is tightly attached to the antenna body 4 under the elastic action of the elastic connecting piece, so as to ensure the firmness of the connection between the antenna body 4 and the frame 1. The frame 1 is provided with the adhesive part 101 on the bottom surface, and the frame 1 is fixed on the mounting surface through the adhesive part 101, so as to connect the antenna body 4 with the mounting surface. The thickness of the frame 1 is greater than the thickness of the antenna body 4, and the antenna body 4 can be lifted upward under the support action of the frame 1, so as to have a certain interval between the antenna body 4 and the mounting surface. In this way, the two side surfaces of the antenna body 4 can be in contact with air, and heat dissipation of the antenna body 4 is realized through the circulation of air. Compared with the double-sided adhesive tape pasted on the bottom surface of the antenna body 4 in the prior art, the mounting mode of the above antenna body 4 makes the antenna body 4 have a larger heat dissipation area, improves the heat dissipation effect of the antenna, and thus improves the stability of the antenna work.

[0034] The two frames 1 are connected through the elastic connecting piece, the distance between the two frames 1 can be adjusted according to the size of the antenna, so that the frame 1 can be suitable for fixing antennas of different sizes. The adhesive part 101 can be double-sided adhesive tape or quick-drying glue, so as to improve the convenience of the connection between the frame 1 and the mounting surface.

[0035] Further improvement is, as shown in Figure 2 and 4 , the opposite sides of the two frames 1 are provided with slots 102 along the direction of their own extension, and the side edges of the antenna body 4 are inserted into the slots 102.

[0036] Specifically, the length of the frame 1 is greater than the length of the side edge of the antenna body 4, so that the antenna body 4 can be completely wrapped between the two frames 1, thereby the frame 1 can better protect the antenna body 4, and the contact area between the frame 1 and the antenna body 4 can be increased, thereby improving the firmness of the connection between the frame 1 and the antenna body 4; the insertion connection can make the connection between the frame 1 and the antenna body 4 more convenient, and improve the convenience of antenna installation.

[0037] Further improvement is, as shown in Figure 2 , the elastic connecting piece is an elastic rope 3.

[0038] Specifically, compared with the spring, the elastic rope 3 has better softness, which can effectively protect the antenna body 4 and reduce the wear between the antenna body 4 and the elastic rope 3; secondly, the elastic rope does not have a spiral structure, so it is thinner and occupies less space, which can reduce the overall volume of the antenna and make the installation of the antenna more convenient.

[0039] Further improvement is, as shown in Figure 2 , the opposite sides of the two frames 1 are provided with hooks 104, and the end of the elastic rope 3 is provided with a rope sleeve connected with the hook 104.

[0040] Specifically, the frame 1 is provided with a plurality of hooks, the number of hooks 104 on the two frames 1 is equal, and the two ends of an elastic rope 3 are respectively connected with one of the hooks 104 on the two frames 1; in this way, a plurality of elastic ropes 3 can be arranged between the two frames 1 to ensure the firmness of the connection between the frame 1 and the antenna body 4; compared with other connection methods, the end of the elastic rope 3 is provided with a rope sleeve connected with the hook 104, which is more convenient and fast, and does not need tools, which can improve the convenience of antenna installation.

[0041] Further improvement is, as shown in Figure 3 , the top and bottom surfaces of the two frames 1 are provided with elastic ropes 3.

[0042] Specifically, the elastic ropes 3 can be distributed above and below the antenna body 4, so that the tension of the elastic ropes 3 on the frame 1 can be balanced in the direction perpendicular to the antenna body 4, thereby improving the stability of the connection between the antenna body 4 and the frame 1.

[0043] Further improvement is, as shown in Figure 5As shown, the frame 1 is provided with a mounting ring 105 for passing bolts.

[0044] Through the connection mode of double-sided tape or glue, the adhesion will gradually decrease over time during long-term use, especially under the influence of environmental factors such as temperature and humidity, the aging speed will accelerate; In view of the above problems, the mounting ring 105 can be used to pass the bolts, and the corresponding threaded holes are opened on the mounting surface, and the frame 1 is installed on the mounting surface through the bolts, which can maintain the firmness of long-term installation.

[0045] Further improvement is, as shown in the drawings, Figure 3 The dust screen 2 is located on the top side and / or bottom side of the antenna body 4.

[0046] During long-term use of the antenna, dust will fall on the surface of the antenna body 4, and the accumulation of a large amount of dust will affect the heat dissipation of the antenna; By setting the dust screen 2, the dust can be blocked, and the accumulation of dust on the antenna body 4 can be reduced, thereby improving the heat dissipation effect of the antenna.

[0047] Further improvement is, as shown in the drawings, Figure 4 The frame 1 is provided with a mounting ring 105 for passing bolts.

[0048] Specifically, the compression part 106 can be rubber material, the end of the dust screen 2 passes through the slot 103 and is wound to the side of the compression part 106 away from the frame 1, and is attached to the compression part 106; During installation of the elastic rope 3, the compression part 106 and the dust screen 2 can be compressed by the elastic rope 3, and since the friction coefficient of rubber is large, the friction between the dust screen 2 and the compression part 106 can be increased to improve the firmness of the connection between them; And the rubber has good elasticity, when disassembling the dust screen 2, the compression part 106 can be pulled away from the frame 1, so as to expand the slot 103, which facilitates the taking and placing of the dust screen 2; The setting of the dust screen 2 can block dust and reduce the accumulation of dust on the antenna body 4, thereby improving the heat dissipation performance of the antenna; Since the slot 103 and the slot 102 have a spacing, the dust screen 2 and the antenna body 4 also have a certain distance, so that the dust screen 2 and the antenna body 4 can maintain air circulation and also block dust, thereby improving the heat dissipation effect of the antenna.
