[0043] Please refer to Figure 1 , Figure 1 the three-dimensional schematic diagram of the antenna fixing device 100 according to an embodiment of the present invention. The antenna fixing device 100 includes an antenna module 110 and a bracket structure 120, and the bracket structure 120 is used to fix the antenna module 110. The antenna module 110 includes a substrate 111 and a connection line 112. The substrate 111 is provided with radiation elements (not shown in the figure), and the connection line 112 is used to connect the substrate 111 and a processing device (not shown in the figure). In Figure 1 the embodiment, the antenna module 110 can be a Digital Enhanced Cordless Telecommunications (DECT) antenna, and the substrate 111 can be a PCB board, but the present invention is not limited thereto.

[0044] Please also refer to Figure 1 , Figure 2 andFigure 3 , wherein Figure 2 shows a three-dimensional schematic diagram of the bracket structure 120 according to Figure 1 the embodiment; and Figure 3 shows a top view of the bracket structure 120 according to Figure 2 the embodiment. The bracket structure 120 includes a body 121, two retaining walls 122, at least one first stop top 124, and at least one second stop top 125. The two retaining walls 122 are respectively connected to two ends of the body 121, and a receiving groove 123 is respectively formed between the retaining walls 122 and the body 121. The first stop top 124 is disposed on the body 121, and at least one second stop top 125 is disposed on at least one of the retaining walls 122.

[0045] The receiving groove 123 is used to receive the antenna module 110. Specifically, a virtual connection line A extends between the two receiving grooves 123 (specifically, Figure 1 in the embodiment, the virtual connection line A extends along the long side direction of the body 121), the first stop top 124 protrudes from the body 121 toward the virtual connection line A, the second stop top 125 protrudes from the retaining wall 122 toward the virtual connection line A, and the first stop top 124 and the second stop top 125 are provided in pairs. In Figure 1 the embodiment, the number of the first stop top 124 and the second stop top 125 is two, and the two retaining walls 122 are respectively provided with the second stop top 125, but the present invention is not limited thereto.

[0046] Specifically, the first stop top 124 and the second stop top 125 are spaced apart by a squeezing space B along a direction p, and the direction p is perpendicular to the virtual connection line A. When the antenna module 110 is received in the receiving groove 123, the first stop top 124 and the second stop top 125 squeeze the substrate 111 of the antenna module 110 from opposite directions toward the squeezing space B to tighten the antenna module 110.

[0047] Thereby, the first stop top 124 and the second stop top 125 can squeeze the substrate 111 from opposite directions by adopting a paired squeezing design with micro-interference, so as to avoid having a shaking gap between the substrate 111 and the receiving groove 123, thereby preventing the antenna module 110 from generating shaking abnormal noise and maintaining the transmission quality of the antenna module 110.

[0048] Please refer to Figures 1 to 4 , wherein Figure 4 shows a cross-sectional schematic diagram of the antenna fixing device 100 according to Figure 1 the embodiment. The bracket structure 120 may further include at least one hook 126 for fixing the antenna module 110. The hook 126 is disposed on the top of the body 121 and includes a hook portion 1261 and an elastic arm 1262, and the elastic arm 1262 connects the hook portion 1261 and the body 121. In Figure 1In the embodiment, the number of the hooks 126 is two, and they are arranged at intervals along the long side direction of the body 121, but the present invention is not limited thereto.

[0049] The engaging portion 1261 is used to fix the antenna module 110 to the receiving groove 123. The engaging portion 1261 has an engaging length c, and the engaging length c is the maximum engaging depth of the engaging portion 1261. The engaging length c is between 0.5 mm and 2.5 mm. One end of the engaging portion 1261 close to the receiving groove 123 has a guiding angle R, and the guiding angle R is a rounded angle. The guiding angle R is used to increase the guiding property when the antenna module 110 is assembled onto the body 121. The elastic arm 1262 has an elastic arm aspect ratio, and the elastic arm aspect ratio is the ratio (h / t) of the long side h to the short side t of the elastic arm 1262. The elastic arm aspect ratio is between 2.7 and 8.0.

[0050] Specifically, when assembling the antenna module 110 to the bracket structure 120, after aligning the two ends of the substrate 111 of the antenna module 110 with the receiving groove 123, it is placed downward through the engaging portion 1261 of the hook 126, so that the substrate 111 is placed into the receiving groove 123 and is simultaneously clamped by the engaging portion 1261. When the substrate 111 is placed downward, it will abut against the engaging portion 1261. The guiding angle R of the engaging portion 1261 can prevent the substrate 111 from interfering with the engaging portion 1261, so that the antenna module 110 can enter the receiving groove 123 more smoothly.

[0051] In addition, the parameter design of the engaging length c of the engaging portion 1261 and the elastic arm aspect ratio of the elastic arm 1262 can enable the substrate 111 to have a good assembly feeling of paragraphs when inserted into the receiving groove 123, which is beneficial to judging whether the assembly is in place.

[0052] Furthermore, the parameter design of the elastic arm aspect ratio can prevent the elastic arm 1262 from breaking when the substrate 111 abuts against the engaging portion 1261.

[0053] Thereby, the bracket structure 120 fixes the antenna module 110 by the clamping of the engaging portion 1261 and the squeezing of the first stop portion 124 and the second stop portion 125. In addition to effectively fixing the antenna module 110 without using any fixing elements (such as screws, back glue, adhesive or curing glue), it is also easy for users to disassemble and recycle, which meets the green design goal.

[0054] Please refer to Figures 1 to 3 , the antenna module 110 may further include a notch 113, and the notch 113 is opened on the substrate 111. The bracket structure 120 may further include an anti-fooling member 127, and the anti-fooling member 127 corresponds to the notch 113. The anti-fooling member 127 is connected to the first stop portion 124 and protrudes from the first stop portion 124 toward the virtual connection line A.

[0055] The anti-fooling part 127 is used to limit the assembly direction of the antenna module 110. The anti-fooling part 127 has an anti-fooling part height b, and the retaining wall 122 of the bracket structure 120 has a retaining wall height L. The ratio (b / L) of the anti-fooling part height b to the retaining wall height L is between 0.2 and 0.8.

[0056] Specifically, since the radiation of the antenna module 110 is directional, the anti-fooling part 127 can define the direction in which the antenna module 110 is fixed to the bracket structure 120. In addition, the parameter design of the ratio of the anti-fooling part height b to the retaining wall height L can ensure the correctness of the assembly direction of the antenna module 110, and at the same time avoid the substrate 111 from breaking due to the notch 113 of the antenna module 110 being set too long.

[0057] Please refer to Figures 1 to 3 , the bracket structure 120 may further include a wire management buckle 128 connected to the body 121. In Figure 1 In the embodiment, the body 121, the retaining wall 122, the first stop top 124, the second stop top 125, the hook 126, the anti-fooling part 127, and the wire management buckle 128 of the bracket structure 120 are integrally formed structures. The wire management buckle 128 includes a wire buckle hole 1281 and an opening 1282. The wire buckle hole 1281 is used to limit the connection wire 112 of the antenna module 110, and the connection wire 112 enters the wire buckle hole 1281 through the opening 1282.

[0058] Specifically, the connection wire 112 of the antenna module 110 has a wire diameter (not shown in the figure). The wire buckle hole 1281 has an aperture d and an outer diameter D, and the opening 1282 has a width w. The wire diameter of the connection wire 112 is denoted as d cable , the ratio (d / d cable ) of the aperture d to the wire diameter is between 1.1 and 1.4, the ratio (w / d cable ) of the width w to the wire diameter is between 0.70 and 0.95, and the ratio (D / d) of the outer diameter D to the aperture d is between 1.5 and 3.0.

[0059] As can be seen from the above embodiments, the bracket structure and the antenna fixing device provided by the present invention have the following advantages:

[0060] First, through the paired squeezing design of the first stop top and the second stop top, the substrate can be squeezed from opposite directions, preventing the antenna module from generating shaking abnormal sounds due to shaking gaps, and thus maintaining the transmission quality of the antenna module.

[0061] Second, the bracket structure fixes the antenna module by the clamping of the hook part and the squeezing of the first stop top and the second stop top. In addition to being able to fix the antenna module without using any fixing elements (such as screws, back glue, adhesive, or curing glue), it is also easy for users to disassemble and recycle, meeting the green design goal.

[0062] Thirdly, the bracket structure is designed with parameters such as guiding angles, engaging lengths, slender ratios of elastic arms, and heights of anti-fooling parts, which is more conducive to the assembly of the antenna module.

[0063] Although the present invention has been disclosed as above in embodiments, it is not intended to limit the present invention. Any person skilled in the art should be able to make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the invention should be defined by the scope of the appended claims.
