[0025] The illustrative embodiments of this application include, but are not limited to, an antenna device. To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this application are described below in conjunction with specific embodiments.

[0026] In scenarios where two metal components in an antenna device need to be installed close together, excessive spacing between the metal components may lead to insufficient coupling and reduced signal transmission efficiency, while insufficient spacing may lead to excessive coupling and affect the antenna's radiation performance. As mentioned earlier, existing antenna devices do not have scenarios requiring small gaps between metal components, and existing metal component installation methods cannot achieve precise control over the gaps between the metal components.

[0027] To address the aforementioned technical problems, this application provides an antenna device comprising an insulating mounting bracket, metal terminals, and an antenna. The insulating mounting bracket includes a base, a first latch, and a second latch. The first and second latches are disposed on a first side of the base along a first direction. The first latch includes a first surface facing the base and a second surface facing away from the base, and is used to latch the metal terminal between the base and the first surface. The second latch includes a third surface facing the base, which is spaced apart from the second surface along the first direction and located on a first side of the second surface. The second latch is used to latch the antenna between the second and third surfaces.

[0028] It can be understood that the distance between the first surface and the second surface is the spacing between the metal terminal and the antenna.

[0029] Thus, by controlling the size of the first latch in the first direction, the distance between the first surface and the second surface can be controlled, thereby enabling precise control of the gap between the metal terminal and the antenna.

[0030] The technical solution of this application will be further described in detail below with reference to the accompanying drawings.

[0031] Figure 1 An exemplary structure of an antenna device 100 provided in an embodiment of this application is shown. (See reference...) Figure 1The antenna device 100 includes an antenna 1, a metal terminal 2, and an insulating mounting bracket 3, with both the antenna 1 and the metal terminal 2 fixed to the insulating mounting bracket 3. For example, the antenna 1 may be a loop radiating antenna. The metal terminal 2 can be used to couple and feed the loop radiating antenna.

[0032] In some embodiments, the antenna device 100 may include at least one antenna 1 and at least two metal terminals 2. For example, the antenna device 100 may include two antennas 1, namely antenna 11 and antenna 12, and may include four metal terminals 2, namely metal terminal 21, metal terminal 22, metal terminal 23 and metal terminal 24.

[0033] In some embodiments, the insulating mounting bracket 3 includes a base 31, a first latch 32 and a second latch 33. The first latch 32 and the second latch 33 are disposed on a first side of the base 31 along the Z direction (as an example of the first direction). The Z direction can be the thickness direction of the antenna device 100, and when the antenna device 100 is in normal use, the direction from the bottom to the top can be the positive Z direction. The first side can be the side of the base 31 facing the positive Z direction.

[0034] The following is for reference. Figure 2A and Figure 2B and combined Figure 4 and Figure 5 This paper introduces an exemplary structure of the first latch 32 and the second latch 33. Figure 2A for Figure 1 A sectional view (AA) of the antenna device 100 shown; Figure 2B This is a magnified view of the dashed area in the AA sectional view; Figure 4 for Figure 1 CC cross-sectional view of the antenna device 100 shown; Figure 5 This is a magnified view of region P1 in the CC section view.

[0035] refer to Figure 2A and Figure 2B The first latch 32 may include a first surface 32a facing the base 31 and a second surface 32b facing away from the base 31. The first latch 32 is used to snap the metal terminal 21 between the base 31 and the first surface 32a. The second latch 33 includes a surface 33a facing the base 31 (as an example of a third surface). Surface 33a and the second surface 32b may be spaced apart along the Z direction, and surface 33a is located on the first side of the second surface 32b. The second latch 33 is used to snap the antenna 12 between the second surface 32b and surface 33a. In this way, the first latch 32 and the second latch 33 can jointly restrict the position of the antenna 12, thereby allowing the antenna 12 to be stably mounted on the insulating mounting bracket 3.

[0036] In some embodiments, the base 31 further includes a fourth surface 31a facing the first side and a boss 311 provided on the fourth surface 31a. A first latch 32 is used to latch the metal terminal 21 between the first surface 32a and the boss 311. In this way, the first latch 32 and the boss 311 can jointly restrict the position of the metal terminal 21, thereby allowing the metal terminal 21 to be stably mounted on the insulating mounting bracket 3.

[0037] It is understood that when the metal terminal 21 and the antenna 12 are mounted on the insulating mounting bracket 3, the antenna 12 is located on the first side of the metal terminal 21 along the Z direction.

[0038] In some embodiments, the installation method of the metal terminal 23 can be the same as that of the metal terminal 21. Correspondingly, the structure of the first latch 32 and the second latch 33 at the installation position of the metal terminal 23 on the insulating mounting bracket 3 can also be the same as the structure of the first latch 32 and the second latch 33 at the installation position of the metal terminal 21.

[0039] In some embodiments, the first latch 32 may include a first hook-shaped portion 321 and a first connecting arm 322, the first connecting arm 322 being connectable to the fourth surface 31a, and, along the Z direction, the first hook-shaped portion 321 being located at the end of the first connecting arm 322 away from the fourth surface 31a. (See reference) Figure 2B The surface of the first hook portion 321 facing the base 31 can form a first surface 32a, and the surface of the first hook portion 321 facing away from the base 31 can form a second surface 32b.

[0040] In some embodiments, there may be two first latches 32, which may be arranged opposite each other along the Y direction (as an example of a second direction), and the Y direction may be perpendicular to the Z direction. Along the Y direction, the two first hook-shaped portions 321 of the two first latches 32 are located between the two first connecting arms 322, and the metal terminal 21 is located between the two first connecting arms 322.

[0041] In some implementations, reference Figure 5 The base 31 may have a first groove 312, which extends along the Z direction and includes at least a first opening 312a facing a first side. For example, the first groove 312 may also include an opening 312b facing a second side, wherein the second side may be a side pointing in the positive X direction, the X direction may be perpendicular to the Y direction, and the X direction may be perpendicular to the Z direction.

[0042] In some embodiments, the metal terminal 21 may include a first portion 211 and a second portion 212 connected together. The first portion 211 of the metal terminal 21 may be snapped between the first surface 32a and the boss 311, and the second portion 212 of the metal terminal 21 may be inserted into the first groove 312.

[0043] In some embodiments, a third latch 313 may also be provided on the base 31, the third latch 313 being used to engage the second part 212 of the metal terminal 21 in the first groove 312.

[0044] In some implementations, reference Figure 2B The projection shape of the metal terminal 21 on the first plane can be T-shaped, wherein the first plane can be parallel to both the Z and Y directions, or in other words, the first plane can be a plane formed by the Z and Y directions. That is to say, the dimension of the first part 211 of the metal terminal 21 in the Y direction is larger than the dimension of the second part 212 in the Y direction, so that the two first latches 32 can easily engage the first part 211 of the metal terminal 21 between the first surface 32a and the boss 311.

[0045] In some implementations, reference Figure 2B , Figure 4 and Figure 5 The second buckle 33 may include a second hook-shaped portion 331 and a second connecting arm 332. The second connecting arm 332 may be connected to the boss 311. The second hook-shaped portion 331 may be provided at the end of the second connecting arm 332 away from the boss 311. Furthermore, the side surface 33a of the second hook-shaped portion 331 facing the base 31 may form a third surface.

[0046] In some embodiments, the cross-section of the second connecting arm 332 may be U-shaped, and this cross-section may be parallel to the Z direction. For example, this cross-section may be located on the plane formed by the X and Z directions, or in other words, this cross-section may be perpendicular to the base 31 and parallel to the X direction.

[0047] The following is for reference. Figure 3A and Figure 3B and combined Figure 4 and Figure 6 This section introduces another exemplary structure for the first latch 32 and the second latch 33.

The second latch 33 may include a surface 34a facing the base 31 (as another example of a third surface). Surface 34a and the second surface 32b may be spaced apart along the Z direction, and surface 34a is located on the first side of the second surface 32b. The second latch 33 is used to snap the antenna 11 between the second surface 32b and surface 34a. In this way, the first latch 32 and the second latch 33 can jointly restrict the position of the antenna 11, thereby allowing the antenna 11 to be stably mounted on the insulating mounting bracket 3.

[0050] In some embodiments, the installation method of the metal terminal 24 can be the same as that of the metal terminal 22. Correspondingly, the structure of the first latch 32 and the second latch 33 at the installation position of the metal terminal 24 on the insulating mounting bracket 3 can also be the same as the structure of the first latch 32 and the second latch 33 at the installation position of the metal terminal 22.

Along the Y direction, the two first hook-shaped portions 321 of the two first latches 32 are located between the two first connecting arms 322, and the metal terminal 21 is located between the two first connecting arms 322.

[0053] In some implementations, reference Figure 3B , Figure 4 and Figure 6The base 31 may further include a connecting portion 314, which may be spaced apart from the boss 311 along the X direction (as an example of a third direction). It is understood that the third direction may be perpendicular to both the second and first directions. The connecting portion 314 may extend along the Y direction and may connect two first connecting arms 322.

Furthermore, the side surface 34a of the third hook-shaped portion 341 facing the metal terminal 22 may form a third surface.

[0056] In some embodiments, the boss 311 may include a support portion 311a and an extension portion 311b connected together. The extension portion 311b may be connected to the fourth surface 31a of the base 31, and the support portion 311a may be connected to the side surface of the extension portion 311b facing the connecting portion 314.
