Description

BACKGROUND Technical Field

[0001] The present disclosure relates to a bracket structure, and in particular to a bracket structure and an antenna fixing device that can avoid mutual influence between two antenna modules. Description of Related Art

[0002] In general products where a Wi-Fi antenna and a Digital Enhanced Cordless Telecommunications (DECT) antenna coexist, the DECT antenna needs to be as far away from the Wi-Fi antenna as possible. If the DECT antenna is located too close to the Wi-Fi antenna, due to insufficient antenna clearance area between the DECT antenna and the Wi-Fi antenna, they will interact with each other and reduce the antenna efficiency.

[0003] In the design of the DECT antenna position, if the Wi-Fi antenna and the DECT antenna are to be placed on the same base, the base needs a huge volume to keep the DECT antenna and the Wi-Fi antenna as far away as possible. However, the large base is not complied with cost considerations. If the DECT antenna is placed on the heat dissipation structure of the product, although it can be far away from the Wi-Fi antenna, being too close to the heat dissipation structure will also cause the DECT antenna characteristics to be affected by the metal parts of the heat dissipation structure.

[0004] In view of this, there is currently a lack of a structure in the market that can make one of the antenna modules away from the other antenna module and metal parts at the same time when two different antenna modules coexist, so the relevant industry is looking for its solution. SUMMARY

[0035] Referring to FIG. 1. FIG. 1 is a schematic view of an electronic device 100 according to an embodiment of the present disclosure. The electronic device 100 includes two first antenna modules 110, a communication base 120, a heat dissipation structure 130, two second antenna modules 140, and two connection structures 150. The heat dissipation structure 130 is disposed on a base (reference number is omitted) and is disposed below the communication base 120. The communication base 120 is configured for the first antenna module 110 to be disposed on. The second antenna module 140 is detachably connected to the communication base 120 through the connection structure 150. Each of the second antenna modules 140 are respectively disposed below each of the first antenna modules 110, and are respectively disposed on two sides of the heat dissipation structure 130. In the embodiment of FIG. 1, the first antenna module 110 can be a Wi-Fi antenna, and the second antenna module 140 can be a Digital Enhanced Cordless Telecommunications (DECT) antenna, but the present disclosure is not limited thereto. It is noted that the electronic devices in other embodiments of the present disclosure, the number of the first antenna modules and the second antenna modules may be one or more than three respectively, and may be disposed on the same side of the electronic device in pairs, and is not limited to FIG. 1. Subsequent descriptions will be given of the first antenna module 110 and the second antenna module 140 corresponding to the same side.

[0036] Referring to FIG. 1 and FIG. 2. FIG. 2 is a partial enlarged view of the electronic device 100 according to the embodiment of FIG. 1. A first distance d1 is between the second antenna module 140 and the first antenna module 110. A second distance d2 is between the antenna module 140 and the heat dissipation structure 130. Specifically, the first distance d1 can be at least 30 mm. The second distance d2 can be at least 10 mm. More specifically, the first distance d1 can be between 60 mm and 70 mm. The second distance d2 can be between 20 mm and 25 mm.

[0037] Therefore, it helps to increase the antenna clearance area of the second antenna module 140 and avoids interference between the second antenna module 140 and the first antenna module 110, which affects the antenna efficiency. It also avoids metal parts of the heat dissipation structure 130 affecting the radiation characteristics of the second antenna module 140. In addition, the second antenna module 140 is designed on the connection structure 150 to be detachably connected to the communication base 120, which can greatly reduce the volume of the communication base 120, thereby reducing the unit price of parts and molding costs.

[0038] Referring to FIG. 1 to FIG. 4 for further explanations. FIG. 3 is a three-dimensional schematic view of the connection structure 150 according to the embodiment of FIG. 1. FIG. 4 is a front view of the connection structure 150 according to FIG. 3. The connection structure 150 is in the shape of lightning (Qoppa Z-shaped) and has an extension direction L. The connection structure 150 is configured for detachably connect to the second antenna module 140 and the communication base 120 along the extension direction L, resulting in the second antenna module 140 being separated from the first antenna module 110 by the first distance d1 and separated from the heat dissipation structure 130 by the second distance d2. The first distance d1 is approximately parallel to the extension direction L, and the second distance d2 is approximately perpendicular to the extension direction L.

[0039] The connection structure 150 includes a fitting part 151, a fixing part 152, and a turning part 153. The turning part 153 is connected between the fitting part 151 and the fixing part 152, and is inclined relative to the fitting part 151 and the fixing part 152. The fitting part 151 is configured to be detachably connected to the communication base 120 along the extension direction L. The fixing part 152 is configured to fix the second antenna module 140. In the embodiment of FIG. 3, the fitting part 151, the fixing part 152, and the turning part 153 are integrally formed.

[0040] The fitting part 151 includes two joint surfaces 1511. The fixing part 152 includes a surface 1521. One of the two joint surfaces 1511 faces the same direction as the surface 1521. An offset distance d3 is between the joint surface 1511 and the surface 1521 along a direction vertical to the extension direction L. Specifically, the turning part 153 is inclined at a first angle 01 relative to the fitting part 151 towards the fixing part 152, and is inclined at a second angle 02 relative to the fixing part 152 towards the fitting part 151. By inclining the two-step deflection structure in which the turning part 153 is inclined at the first angle 01 and the second angle 02, an offset distance d3 can be generated between the joint surface 1511 and the surface 1521, so that when the second antenna module 140 is fixed to the fixing part 152, it can maintain a distance from the heat dissipation structure 130. In the embodiment of FIG. 4, the first angle 01 is equal to the second angle 02. The surface 1521 is parallel to the joint surface 1511. The offset distance d3 can be between 3 mm and 50 mm, such as about 8.67 mm, but the present disclosure is not limited thereto. Without considering the rest of the factors such as the overall configuration, the offset distance d3 can be increased to obtain better antenna isolation.

[0041] Referring to FIG. 1 and FIG. 3 to FIG. 6. FIG. 5 is a bottom view of the communication base 120 according to the embodiment of FIG. 1. FIG. 6 is a schematic view of the connection between the fitting part 151 of the connection structure 150 and the socket structure 121 of the communication base 120 according to the embodiment of FIG. 1. The communication base 120 includes two socket structures 121 (as shown in FIG. 5) configured to be fastened by the fitting part 151. It is noted that, the number of socket structures 121 corresponds to the number of the connection structures 150. The number of the socket structures may be one or more than three in the electronic device in other embodiments of the present disclosure, and is not limited to FIG. 5. The fitting part 151 can further include two engagement portions 1512 and at least one restrictive portion 1513. The engagement portion 1512 is connected to an end of the joint surface 1511 away from the turning part 153. At least one restrictive portion 1513 is connected to at least one of the two joint surfaces 1511, and is adjacent to at least one of the two engagement portions 1512. In the embodiment of FIG. 3, the number of the restrictive portions 1513 is two, but the present disclosure is not limited thereto. As shown in FIG. 6, the engagement portion 1512 corresponds to the socket structure 121 of the communication base 120. The engagement portion 1512 is configured to extend into and fasten the top of the socket structure 121, and is detachably connected to the second antenna module 140 and the communication base 120 along the extension direction L. When the engagement portion 1512 is fastened to the socket structure 121, the restrictive portion 1513 is configured to be embedded in two sides of the socket structure 121 to prevent the engagement portion 1512 from falling off from the socket structure 121 due to external force factors such as bending or shaking.

[0042] Therefore, the disassembly design of connecting the socket structure 121 of the communication base 120 through the fitting part 151 of the connection structure 150 can greatly reduce the complexity of the assembly operation of the second antenna module 140, thereby reducing the assembly man-hours and thus the assembly cost. In addition, by fastening the fitting part 151 on the socket structure 121, the connection structure 150 and the communication base 120 are assembled without the use of screws or gluing, making it easy to disassemble and facilitate recycling, which complies with the sustainable recycling goals of green design.

[0043] Referring to FIG. 1 to FIG. 4, FIG. 7 and FIG. 8. FIG. 7 is a schematic view of the second antenna module 140 fixed by the fixing part 152 of the connection structure 150 according to the embodiment of FIG. 1. FIG. 8 is another schematic view of the second antenna module 140 fixed by the fixing part 152 of the connection structure 150 according to the embodiment of FIG. 1. The fixing part 152 may further include a fixing surface 1522, two retaining walls 1523, at least one hook 1524, at least one first stop part 1526, and at least one second stop part 1527. The fixing surface 1522 is opposite to the surface 1521. The two retaining walls 1523 are connected to two ends of the surface 1521 respectively, and respectively form an accommodating groove 1525 with the fixing surface 1522. The at least one hook 1524 is disposed on the fixing surface 1522 and is between the two retaining walls 1523. The at least one first stop part 1526 is disposed on the fixing surface 1522. The at least one second stop part 1527 is disposed on the retaining wall 1523. In the embodiment of FIG. 3, the number of the at least one hook 1524, the number of the at least one first stop part 1526 and the number of the at least one second stop part 1527 are two, but the present disclosure is not limited thereto.

[0044] As shown in FIG. 7 and FIG. 8, the accommodating groove 1525 is configured to accommodate a substrate (reference number is omitted). The hook 1524 is configured to fix the second antenna module 140 to the accommodating groove 1525. The first stop part 1526 and the second stop part 1527 are configured to tighten the second antenna module 140. Specifically, the first stop part 1526 and the second stop part 1527 are disposed in pairs. The first stop part 1526 protrudes from the fixing surface 1522, and the second stop part 1527 protrudes from the retaining wall 1523 towards the fixing surface 1522. When the second antenna module 140 is accommodated in the accommodating groove 1525, the second antenna module 140 can be fastened and fixed in the accommodating groove 1525 through the hooks 1524. At the same time, the first stop part 1526 and the second stop part 1527 can clamp and slightly bend the substrate of the second antenna module 140 from opposite direction to press and tighten the second antenna module140.

[0045] Therefore, the first stop part 1526 and the second stop part 1527 can clamp and slightly bend the second antenna module 140 from opposite directions through a micro-interference clamping pair design, thereby avoiding the shaking gap between the second antenna module 140 and the accommodating groove 1525 so as to prevent the second antenna module 140 from producing shaking noise, and thus maintaining the transmission quality of the second antenna module 140.

[0046] From the above embodiment, the connection structure and the electronic device provided by the present disclosure have the following advantages:

[0047] First, the antenna clearance area of the second antenna module can be increased through the connection structure, and the second antenna module is far away from the first antenna module and the heat dissipation structure at the same time, so that in addition to avoiding the interaction between the first antenna module and the second antenna module, the radiation characteristics of the antenna module can also be avoided from being affected by metal parts.

[0048] Second, by designing the second antenna module on the connection structure to detachably connect the communication base, the volume of the communication base can be greatly reduced, the unit price of parts and the molding costs can be reduced, and the complexity of the assembly operation of the second antenna module can be greatly reduced, thereby reducing the assembly man-hours and thus the assembly cost.

[0049] Third, the assembly of the connection structure and the communication base can be connected without the use of any fixing components (e.g., screws, backing adhesive, adhesive, or curing glue) and is also easy for users to disassemble and recycle, which is complied with the green design goal.
