Description

Technical Field

[0001] The invention relates to an antenna, and in particular to an antenna arranged in a heat dissipation port. Background Art

[0002] In addition to pursuing small size and light weight, mobile terminal devices also require high performance. Whether in business or consumer use, except for handheld mobile phones (cell phones) which are limited by the size of the device and cannot have the same performance as desktop computers, other types of mobile terminals such as notebook computers, laptop computers and tablet computers can have performance similar to that of desktop computers.

[0003] However, strong performance means higher power consumption, and higher performance means higher power consumption, and more waste heat is generated when the electronic components are in operation. In order to reduce the component temperature caused by waste heat generated when the electronic device is working, active air convection heat dissipation is usually used. In addition to using a fan inside the device, at least one heat dissipation port is required to discharge the hot air outside the device. Existing heat sink devices usually only integrate visual aesthetics for the appearance of the device, and do not have other functions for device performance. Summary of the invention

[0004] In view of the above-mentioned defects of the prior art, the task of the present invention is to provide an antenna disposed in a heat dissipation port, so as to solve the problem of single function of the heat sink and improve the integration degree of the heat sink and the antenna assembly.

[0005] The technical solution of the present invention is as follows: an antenna arranged in a heat dissipation port, comprising: The heat dissipation frame has a plurality of first openings and a plurality of second openings; A main antenna body having a main antenna pattern and a plurality of first alignment openings, wherein the first alignment openings are aligned with the first openings and are attached to the heat dissipation frame; and The auxiliary antenna body has an auxiliary antenna pattern and a plurality of second alignment openings, wherein the second alignment openings are aligned with the second openings and are attached to the heat dissipation frame.

[0006] Furthermore, the heat dissipation frame is used to be installed on a notebook computer, a laptop computer or a tablet computer.

[0007] Furthermore, the first opening and the second opening are used to allow heat dissipation airflow to pass through.

[0008] Furthermore, the main antenna body and the auxiliary antenna body are both laser engraved components.

[0009] Furthermore, the main antenna pattern has a first feeding point, which is connected to a first coaxial cable; the auxiliary antenna pattern has a second feeding point, which is connected to a second coaxial cable.

[0010] Furthermore, the first coaxial cable and the second coaxial cable are both fastened to the heat dissipation frame by using fasteners.

[0011] Furthermore, the antenna includes an isolator having a grounded metal pattern for improving antenna isolation between the main antenna body and the auxiliary antenna body, and the grounded metal pattern shares a common ground with the first coaxial cable and the second coaxial cable.

[0012] Furthermore, the main antenna body and the auxiliary antenna body are both joined to the heat dissipation frame by hot-melt method.

[0013] Furthermore, the main antenna body and the auxiliary antenna body are used to operate in a wireless wide area network, a wireless local area network and a 5G sub-6 frequency band, including a frequency range of 617MHz to 960MHz, a frequency range of 1710MHz to 2690MHz, a frequency range of 3300MHz to 4900MHz, and a frequency range of 5100MHz to 5900MHz.

[0014] Furthermore, the heat dissipation frame has a first inner side and a second inner side, and the first inner side and the second inner side are perpendicular to each other, so that the first inner side and the second inner side are L-shaped.

[0015] The advantages of the present invention compared with the prior art are: The present invention integrates the antenna, which takes up a considerable space and is used as an electromagnetic energy transmitting and receiving port (or transmitting and receiving area), into the interior of the radiator, thereby improving the degree of component integration and having the effect of improving the overall integration of the necessary components of the device itself. In addition, by utilizing the large space of the heat dissipation port, the shielding effect of the metal of the device body itself can be reduced, thereby improving the antenna performance.

[0027] The present invention will be further described below in conjunction with the embodiments, but are not intended to limit the present invention.

[0028] Please refer to Figures 1 to 11 The antenna disposed in the heat dissipation port provided in the embodiment of the present invention is illustrated as follows with the accompanying icons. Figure 1 Schematic diagram of the heat dissipation vent position 100 of a laptop provided in an embodiment of the present invention. The heat dissipation vent is usually located where the user's hands will not touch during operation so as not to affect the user experience. For example, it may usually be located near the connection between the host's hinge and the screen, but the present invention is not limited to this. Figure 1 The X-axis is parallel to the edge of the case and parallel to the axis of rotation; the positive Y-axis direction (+Y) is equivalent to the direction from the heat dissipation port to the outside (from the heat dissipation port away from the body), that is, the direction of the heat dissipation airflow output; in addition, the Z-axis is defined based on the XY axis using the right-hand rule. Fig.11 Schematic diagram of a heat dissipation frame 1 of an antenna provided in a heat dissipation port according to an embodiment of the present invention. The heat dissipation frame 1 is usually non-metallic and non-conductive. Figure 2 , Figure 3 and Fig.11 , Figure 2 This is the top view. Figure 3The antenna disposed in the heat dissipation port includes a heat dissipation frame 1 , a main antenna body 2 and an auxiliary antenna body 3 . Figure 2 The top surface shown is the inner surface of the heat dissipation frame 1 when it is installed in the housing. Figure 3 The positions of two antenna bodies and corresponding feed lines in the heat dissipation frame 1 are shown, which will be described later. The heat dissipation frame 1 is used to be installed in a notebook computer, a laptop computer or a tablet computer. The antenna placed in the heat dissipation port of the embodiment of the present invention is particularly suitable for notebook computers, laptop computers or tablet computers with a metal casing. The antenna as a transceiver of electromagnetic wave signals is integrated into the interior of the heat sink (heat dissipation frame 1), so the antenna design does not need to use other blocks of the casing, and the casing does not need to be specially designed with a non-metallic antenna window (for electromagnetic wave transmission and reception).

[0029] in addition, Figure 4 It is a schematic diagram of the left side of the antenna arranged in the heat dissipation port, that is, it corresponds to the schematic diagram of the left side of the heat dissipation frame 1. Figure 5 It is a right side schematic diagram of the antenna disposed in the heat dissipation port, that is, it corresponds to the right side schematic diagram of the heat dissipation frame 1. The heat dissipation frame 1 has a first inner side 13 and a second inner side 14, and the first inner side 13 and the second inner side 14 are perpendicular to each other, so that the first inner side 13 and the second inner side 14 are L-shaped.

[0030] refer to Figure 2 and Figure 6 , Figure 6 This is a bottom view, which is the part exposed on the surface of the case after the heat dissipation frame 1 is installed in the laptop computer. In other words, the top surface of the heat dissipation frame 1 is located on the body component and after the assembly is fitted, the bottom surface of the heat dissipation frame 1 becomes a part of the case (integrated with the case). Figure 6 The bottom view shows that the bottom surface of the heat dissipation frame 1 (equivalent to the bottom surface of the antenna disposed in the heat dissipation port) has a plurality of first openings 11 and a plurality of second openings 12. These openings are usually open spaces facing the user's use state, such as near the connection between the hinge and the screen, and away from the user. When used in a tablet computer, these openings are changed according to the user's hand-holding method, but because the screen and the main body are combined, no matter which direction the opening is, it will not be blocked by the screen, and the direction toward the outside of the casing is open space. It is worth mentioning that Figure 6 As the bottom view of the antenna, it is actually combined with the housing. Figure 1 The laptop user mode is the side facing away from the user.

[0031] Furthermore, refer to Figures 7 to 9 , Figure 7 This is a schematic diagram of the back side, which is actually the bottom side of the main body of the notebook computer after being combined with the casing. Figure 8It is a three-dimensional schematic diagram of an antenna disposed in a heat dissipation port provided by an embodiment of the present invention, viewed from an oblique front angle. Fig. 9 1 is a three-dimensional schematic diagram of an antenna disposed in a heat dissipation port provided by an embodiment of the present invention, viewed from an oblique angle from the back.

Figure 2 and Fig.10 The main antenna body 2 has a main antenna pattern 21 and a plurality of first alignment openings 22, the plurality of first alignment openings 22 are aligned with the plurality of first openings 11 and fit the heat dissipation frame 1. The auxiliary antenna body 3 has an auxiliary antenna pattern 31 and a plurality of second alignment openings 32, the plurality of second alignment openings 32 are aligned with the plurality of second openings 12 and fit the heat dissipation frame 1.

[0033] The aforementioned plurality of first openings 11 and the aforementioned plurality of second openings 12 are used to allow heat dissipation airflow to pass through. The shapes of the aforementioned plurality of first openings 11 and the aforementioned plurality of second openings 12 can be the same as each other to simplify the process or to match the design of the structural appearance, but this is not limited to this. The number of the first openings 11 and the number of the second openings 12 are, for example, 5 to 10 each, and the number of the first openings 11 and the number of the second openings 12 can be the same as each other, but this is not limited to this.

Fig.10 The corresponding relationship between the main antenna body 2 and the first coaxial cable 4 is shown, and the corresponding relationship between the auxiliary antenna body 3 and the second coaxial cable 5 is shown. Fig.10The main antenna body 2 and the auxiliary antenna body 3 are both laser engraved components, which can be designed to match the shape of the heat dissipation frame 1 to improve the integration of the antenna product and the heat dissipation frame 1, and even to optimize or reduce the structure. In this embodiment, the main antenna body 2 and the auxiliary antenna body 3 are both joined to the heat dissipation frame 1 by hot melting, but the assembly method is not limited to this. The main antenna pattern 21 is Fig.10 The oblique line block shown indicates that there is a first feed point 211, and the first feed point 211 is connected to the first coaxial cable 4.
