Abstract
Description
Technical Field
[0001] The present invention relates to a connection structure, and particularly to a connection structure and an electronic device that can avoid mutual influence between two antenna modules. Background Art
[0002] In products where a general 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 position of the DECT antenna is too close to the Wi-Fi antenna, due to insufficient antenna clearance between the DECT antenna and the Wi-Fi antenna, they will influence each other and cause a decrease in antenna efficiency.
[0003] In the design of the position of the DECT antenna, if the Wi-Fi antenna and the DECT antenna are to be jointly disposed on the same base, the base needs to have a very large volume to keep the DECT antenna as far away from the Wi-Fi antenna as possible. However, a large-volume base does not meet cost considerations. If the DECT antenna is disposed 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 characteristics of the DECT antenna to be affected by the metal parts of the heat dissipation structure.
[0004] In view of this, there is currently a lack in the market of a structure that can keep one antenna module away from another antenna module and metal parts simultaneously when two different antenna modules coexist, so relevant industries are seeking solutions thereto.
[0005] Therefore, a connection structure and an electronic device are needed to solve the above problems. Summary of the Invention
[0006] An object of the present invention is to provide a connection structure and an electronic device, which, through the inclined design of the connection structure, can not only avoid mutual influence between different two antenna modules in the electronic device, but also avoid the antenna characteristics of the antenna module being affected by metal parts.

Wherein, one of the two joint surfaces of the fitting and the surface of the fixing member face the same direction, and there is a misalignment distance along the vertical extension direction between one of the two joint surfaces and the surface.
[0008] Another embodiment according to the structural aspect of the present invention provides an electronic device, which includes a first antenna module, a communication base, a heat dissipation structure, a second antenna module, and a connection structure. The communication base is used for setting the first antenna module. The heat dissipation structure is disposed below the communication base. The second antenna module is disposed below the first antenna module and on one side of the heat dissipation structure, wherein there is a first distance between the second antenna module and the first antenna module, and a second distance between the second antenna module and the heat dissipation structure. The connection structure has an extending direction. The connection structure is used for detachably connecting the second antenna module and the communication base along the extending direction, and the connection structure includes a fitting, a fixing member, and a turning member. The fitting includes two engaging surfaces. The fixing member includes a surface.

[0044] Please refer to Figure 1 as shown Figure 1Schematic diagram of an electronic device 100 according to an embodiment of the present invention. 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 (not labeled separately) and is disposed below the communication base 120. The communication base 120 is used for the first antenna module 110 to be disposed. The second antenna module 140 is detachably connected to the communication base 120 through the connection structure 150. Each second antenna module 140 is respectively disposed below each first antenna module 110 and is respectively disposed on two sides of the heat dissipation structure 130. In Figure 1 the embodiment, the first antenna module 110 can be a Wi-Fi antenna; the second antenna module 140 can be a Digital Enhanced Cordless Telecommunications (DECT) antenna, but the present invention is not limited thereto. It should be noted that in the electronic devices of other embodiments of the present invention, the number of the first antenna module and the second antenna module can each be one or more than three, and can be disposed in pairs on the same side of the electronic device, not limited to Figure 1 the disclosed content. Subsequently, the first antenna module 110 and the second antenna module 140 corresponding to the same side will be described.
[0045] Please refer to Figure 1 and Figure 2 As shown, there is a first distance d1 between the second antenna module 140 and the first antenna module 110, and there is a second distance d2 between the second 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.
[0046] Thereby, it helps to increase the antenna clearance area of the second antenna module 140, and avoids the mutual influence of the antenna efficiency between the second antenna module 140 and the first antenna module 110. At the same time, it also avoids the metal parts of the heat dissipation structure 130 from affecting the radiation characteristics of the second antenna module 140. In addition, designing the second antenna module 140 on the connection structure 150 to be detachably connected to the communication base 120 can greatly reduce the volume of the communication base 120, and can reduce the unit price of parts and the mold opening cost.
[0047] For further illustration, please refer to Figures 1 to 4 as shown, in which Figure 3 shows a three-dimensional schematic diagram of the connection structure 150 in the embodiment according to Figure 1 ; and Figure 4 shows a three-dimensional schematic diagram of the connection structure 150 in the embodiment according to Figure 3Front view of the connection structure 150. The connection structure 150 is generally in a lightning shape (Qoppa Z-shaped) and has an extending direction L. The connection structure 150 is used to detachably connect the second antenna module 140 and the communication base 120 along the extending direction L, so that the second antenna module 140 is separated from the first antenna module 110 by a first distance d1 and from the heat dissipation structure 130 by a second distance d2, where the first distance d1 is substantially parallel to the extending direction L and the second distance d2 is substantially perpendicular to the extending direction L.
[0048] The connection structure 150 includes a fitting 151, a fixing member 152, and a turning member 153. The turning member 153 is connected between the fitting 151 and the fixing member 152 and is inclined relative to the fitting 151 and the fixing member 152. The fitting 151 is used to detachably connect the communication base 120 along the extending direction L, and the fixing member 152 is used to fix the second antenna module 140. In Figure 3 the embodiment, the fitting 151, the fixing member 152, and the turning member 153 are integrally formed structures.
[0049] The fitting 151 includes two engaging surfaces 1511, and the fixing member 152 includes a surface 1521. One of the two engaging surfaces 1511 and the surface 1521 face the same direction, and there is a misalignment distance d3 between the engaging surface 1511 and the surface 1521 along the direction perpendicular to the extending direction L. Specifically, the turning member 153 is inclined relative to the fitting 151 towards the fixing member 152 by a first angle θ1 and relative to the fixing member 152 towards the fitting 151 by a second angle θ2. By means of the secondary deflection structure of the turning member 153 inclining by the first angle θ1 and the second angle θ2, a misalignment distance d3 can be generated between the engaging surface 1511 and the surface 1521, so that when the second antenna module 140 is fixed to the fixing member 152, it can maintain a distance from the heat dissipation structure 130. In Figure 4 the embodiment, the first angle θ1 is equal to the second angle θ2, the surface 1521 is parallel to the engaging surface 1511, and the misalignment distance d3 can be between 3 mm and 50 mm, for example, about 8.67 mm, but the present invention is not limited thereto. Without considering other factors such as the overall configuration, the misalignment distance d3 can be increased to obtain better antenna isolation.
[0050] Please refer to Figure 1 and Figures 3 to 6 as shown, where Figure 5 shows a bottom view of the communication base 120 in the embodiment according to Figure 1 ; and Figure 6 shows a schematic diagram of the fitting 151 of the connection structure 150 connecting the socket structure 121 of the communication base 120 in the embodiment according to Figure 1 . The communication base 120 includes two socket structures 121 (as Figure 5As shown, it is used for the fitting 151 to engage. It should be noted that the number of the socket structures 121 corresponds to the number of the connection structures 150. In the electronic devices of other embodiments of the present invention, the number of the socket structures can be one or more than three respectively, not limited to Figure 5 the disclosed content. The fitting 151 may further include two engaging portions 1512 and at least one limiting portion 1513. The engaging portions 1512 are connected to one end of the joint surface 1511 away from the turning member 153, and at least one limiting portion 1513 is connected to at least one of the two joint surfaces 1511, adjacent to at least one of the two engaging portions 1512. In Figure 3 the embodiment, the number of the limiting portions 1513 is two, but the present invention is not limited thereto. As Figure 6 shown, the engaging portions 1512 correspond to the socket structures 121 of the communication base 120. The engaging portions 1512 are used to extend into and engage with the tops of the socket structures 121, and detachably connect the second antenna module 140 and the communication base 120 along the extending direction L. When the engaging portions 1512 are engaged with the socket structures 121, the limiting portions 1513 are used to be embedded on two sides of the socket structures 121 to prevent the engaging portions 1512 from falling off the socket structures 121 due to external force factors such as bending or shaking.
[0051] Thus, through the detachable design of the fitting 151 of the connection structure 150 connecting the socket structures 121 of the communication base 120, the complexity of the assembly operation of the second antenna module 140 can be greatly reduced, the assembly man-hours can be reduced, and further the assembly cost can be reduced. In addition, by using the fitting 151 to be snap-fitted and positioned in the socket structures 121, the assembly of the connection structure 150 and the communication base 120 does not require the use of screws or gluing, is easy to disassemble and is conducive to recycling, meeting the goal of green design and sustainable cycle.
[0052] Please refer to Figures 1 to 4 and Figures 7 to 8 shown, wherein Figure 7 it shows a schematic diagram of the fixing member 152 of the connection structure 150 fixing the second antenna module 140 in the embodiment according to Figure 1 ; and Figure 8 it shows another schematic diagram of the fixing member 152 of the connection structure 150 fixing the second antenna module 140 in the embodiment according to Figure 1 . The fixing member 152 may further include a fixing surface 1522, two retaining walls 1523, at least one hook 1524, at least one first stopping top 1526 and at least one second stopping top 1527. The fixing surface 1522 is opposite to the surface 1521. The two retaining walls 1523 are respectively connected to two ends of the fixing surface 1522, and respectively form a receiving groove 1525 with the fixing surface 1522. The hook 1524 is arranged on the fixing surface 1522 and is located between the two retaining walls 1523. The first stopping top 1526 is arranged on the fixing surface 1522, and the second stopping top 1527 is arranged on the retaining wall 1523. InFigure 3 In the embodiment, the number of the hooks 1524, the number of the first stopping tops 1526, and the number of the second stopping tops 1527 are all two, but the present invention is not limited thereto.
[0053] As Figure 7 and Figure 8 shown, the receiving groove 1525 is used to receive a substrate (not labeled separately) of the second antenna module 140. The hook 1524 is used to fix the second antenna module 140 in the receiving groove 1525. The first stopping top 1526 and the second stopping top 1527 are used to press the second antenna module 140 tightly. Specifically, the first stopping top 1526 and the second stopping top 1527 are arranged in pairs. The first stopping top 1526 protrudes from the fixing surface 1522, and the second stopping top 1527 protrudes from the retaining wall 1523 toward the fixing surface 1522. When the second antenna module 140 is received in the receiving groove 1525, the second antenna module 140 can be fixed in the receiving groove 1525 by the engagement of the hook 1524. At the same time, the first stopping top 1526 and the second stopping top 1527 can squeeze the substrate of the second antenna module 140 from opposite directions to press the second antenna module 140 tightly.
[0054] Thereby, through the paired squeezing design with micro-interference of the first stopping top 1526 and the second stopping top 1527, the second antenna module 140 can be squeezed from opposite directions, so as to avoid having a shaking gap between the second antenna module 140 and the receiving groove 1525, and further prevent the second antenna module 140 from generating shaking abnormal sounds, so as to maintain the transmission quality of the second antenna module 140.
[0055] It can be seen from the above embodiments that the connection structure and the electronic device provided by the present invention have the following advantages:
[0056] First, connecting through the connection structure can increase the antenna clearance area of the second antenna module, and make the second antenna module away from the first antenna module and the heat dissipation structure at the same time. In addition to being able to avoid the mutual influence between the first antenna module and the second antenna module, it can also avoid the radiation characteristics of the antenna module being affected by metal parts.
[0057] Second, by designing the second antenna module on the connection structure and detachably connecting it to the communication seat body, the volume of the communication seat body can be greatly reduced, the unit price of parts and the mold opening cost can be reduced, and the complexity of the assembly operation of the second antenna module can be greatly reduced, so as to reduce the assembly man-hours, and further reduce the assembly cost.
[0058] Third, the assembly of the connection structure and the communication seat body can be connected without using any fixing elements (such as screws, back glue, adhesive or curing glue), and is also easy for users to disassemble and recycle, which meets the green design goal.
[0059] 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 modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the protection scope of the invention should be determined by the scope defined in the appended claims.
