Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of terminal technology, and in particular to a structural component and electronic equipment integrated with an antenna. Background Art
[0002] Currently, electronic devices are trending towards narrow screen bezel designs, which can enhance the visual experience. However, this also limits the structural space in the screen area, making it difficult to accommodate traditional antenna systems.

To address this issue, antennas can be placed on the system side of the electronic device. However, when placed on the system side, the antenna is closer to the electromagnetic noise source, increasing the noise reduction cost on the system side. Utility Model Content

[0026] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.
[0027] Figure 1 FIG. 1 shows a schematic diagram of the structure of a structural component integrated with an antenna according to an embodiment of the present disclosure. Figure 1 As shown, the structural component includes: a coupling feed branch 1, an electronic device housing 2 and a wireless radiation branch 3; wherein, the coupling feed branch 1 is arranged on the inner surface of the electronic device housing 2, and is used to transmit the electrical signal transmitted by the radio frequency cable 4 to the wireless radiation branch 3 by coupling; the wireless radiation branch 3 is arranged on the outer surface of the electronic device housing 2, and is used to convert the electrical signal transmitted by the coupling feed branch 1 into electromagnetic waves for radiation.
[0028] Among them, the electronic device housing 2 is a supporting structure for the coupling feed branch 1 and the wireless radiation branch 3, and can specifically be a structure such as the top cover of a laptop computer or the back cover of a tablet computer. The coupling feed branch 1 is arranged on the inner surface of the electronic device housing 2, and is used to transmit the electrical signal from the radio frequency cable 4 to the wireless radiation branch 3 by coupling. The coupling method can be achieved by utilizing the change of the electromagnetic field, and the coupling method is not limited here. Specifically, the coupling feed branch 1 can be prepared by materials such as PCB (Printed Circuit Board), FPC (Flexible Printed Circuit), FFC (Flat Flexible Cable) or metal. The wireless radiation branch 3 is a metal sheet or strip with a special shape. The specific shape can be set according to the specific situation and is not specifically limited in this disclosure. The wireless radiation branch 3 is made on the outer surface of the electronic device housing 2 by printing or spraying, and is used to convert the electrical signal received from the coupling feed branch 1 into electromagnetic waves and radiate them into the surrounding space. This allows other wireless devices to receive these electromagnetic waves, thereby realizing wireless communication between devices.
[0029] The wireless devices of electronic devices are usually set around the screen. If the wireless devices take up a large space, it will make it difficult for the electronic device to achieve the design requirements of the narrow screen frame. The present disclosure realizes the antenna function by adopting the coupling feeding method on the inner and outer surfaces of the electronic device casing, which greatly optimizes the internal space of the electronic device and can meet the design requirements of the narrow frame of the electronic device. Compared with the printed antenna in the prior art, the present disclosure adopts the out-of-plane coupling feeding method, which does not require perforation, welding and other operations on the electronic device casing, making the casing of the electronic device more beautiful. Compared with the method of setting the antenna on the system end in the prior art, the structure of the present disclosure sets the antenna on the screen side of the electronic device, which does not require SAR (Specific Absorption Rate) testing of the electronic device, and can save SAR certification costs.
[0030] In one embodiment of the present disclosure, the electronic device housing 2 is non-metallic.
[0031] Because metal is conductive, it shields electromagnetic waves, limiting the ability of wireless radiation branch 3 to radiate electromagnetic waves outward and potentially interfering with the signal received by coupled feed branch 1. Therefore, the electronic device housing 2 in this disclosure is made of a non-metallic material. In one embodiment, materials such as plastic and basalt may be used.
[0032] In one embodiment of the present disclosure, Figure 2As shown, the coupled feed branch 1 includes a first feed branch 11 and a second feed branch 12. There is no direct electrical connection between the first feed branch 11 and the second feed branch 12; instead, they interact through coupling. This design significantly reduces the size of the coupled feed branch 1, thereby addressing the limited internal space issues associated with narrow-frame designs for electronic devices.
[0033] In one embodiment of the present disclosure, Figure 2 As shown, the RF cable 4 includes an inner conductor 42 and an outer conductor 41, and the inner conductor 42 and the outer conductor 41 are concentrically arranged; the inner conductor 42 of the RF cable 4 is connected to the second feeding branch 12 for transmitting the electrical signal transmitted by the RF cable 4 to the wireless radiation branch 3; the outer conductor 41 of the RF cable 4 is connected to the first feeding branch 11 for the return of the electrical signal.
[0034] RF cable 4 is a coaxial cable used to transmit RF signals. It includes at least an inner conductor 42 and an outer conductor 41. These conductors are typically concentric, with the inner conductor 42 located at the center of the cable and the outer conductor 41 surrounding it as a shield. Inner conductor 42 is connected to the second feed branch 12 and transmits the RF signal generated by the signal source to the second feed branch 12, while also receiving the RF signal radiated by the antenna. Outer conductor 41 prevents external electromagnetic interference from affecting the signal and provides a return path for current, ensuring current balance in the antenna system.
[0035] In one embodiment of the present disclosure, the structural member further includes a paint layer, and the paint layer covers the wireless radiation branch.
[0036] After the wireless radiation branch 3 is arranged on the outer surface of the electronic device housing 2, the outer surface is sprayed with paint to form a spray paint layer on the surface. The spray paint layer can make the electronic device surface more beautiful and can protect the wireless feeding branch 3.
[0037] In one embodiment of the present disclosure, the thickness of the electronic device housing 2 is greater than or equal to 0.8 mm and less than or equal to 1.8 mm. The thickness of the electronic device housing 2 affects the performance of the antenna. The smaller the thickness, the better the antenna performance. To achieve a high level of antenna performance, the electronic device housing 2 preferably has a thickness of 0.8 mm to 1.8 mm.
[0038] In one embodiment of the present disclosure, the coupling feed branch 1 is 40 mm long and 2 mm wide. The present disclosure does not specify the specific material, shape, quantity, etc. of the coupling feed branch 1, and the material, shape, and quantity can be selected based on actual application requirements. To meet the design requirements of narrow bezels for electronic devices, the present disclosure preferably uses a coupling feed branch 1 with a length of 40 mm and a width of 2 mm.
[0039] like Figure 3 As shown, in one embodiment of the present disclosure, the wireless radiation branch 3 is 40 mm long and 12 mm wide. Similarly, the present disclosure does not specifically limit the specific material, shape, and number of the wireless radiation branch 3, and can be selected based on actual application requirements. To meet the design requirements of achieving high transmission efficiency with the feeding coupling branch 1 and realizing a narrow frame of the electronic device, the present disclosure preferably uses a wireless feeding branch 3 with a length of 40 mm and a width of 12 mm.
[0040] Another aspect of the present disclosure discloses an electronic device, which includes the structural member with integrated antenna function in the above embodiment. The electronic device can be a laptop, a tablet computer, a smart phone, etc. For example, the electronic device is a laptop. In this case, the electronic device housing is the top cover of the laptop. Figure 4 A schematic diagram of the inner surface of an electronic device housing according to an embodiment of the present disclosure is shown. Figure 4 As shown, the inner surface of the top cover of the notebook computer is provided with a coupling feeding branch 1 , which is connected to the radio frequency cable 4 . Figure 5 A schematic diagram of the outer surface of an electronic device housing according to an embodiment of the present disclosure is shown. Figure 5 As shown, the outer surface of the top cover of the notebook computer is provided with wireless radiation branches 3.
[0041] Figure 6 A schematic diagram of a process flow for manufacturing a structural member according to an embodiment of the present disclosure is shown. Figure 6 As shown, continuing with the example of a laptop computer, a plastic structural member for the laptop's top cover is first obtained. Wireless radiation branches 3 are then formed on the outer surface of the plastic structural member using printing or spraying techniques, resulting in a semi-finished product having wireless radiation branches 3 on the outer surface. Paint is then sprayed on the outer surface to form a paint layer, resulting in a finished plastic structural member. The finished plastic structural member is then assembled with the feed coupling branch 1 and the RF cable 4 to obtain a structural member with an integrated antenna.
[0042] Through experimental comparison, it was found that, on the one hand, the out-of-plane coupling antenna system disclosed in the present invention can save a certain amount of manufacturing costs and has better antenna performance compared to the traditional antenna system. In addition, it is smaller in size, which can save internal space of electronic devices and meet the design requirements of narrow bezels of electronic devices. On the other hand, the out-of-plane coupling antenna system disclosed in the present invention can be set on the side of the screen, eliminating the need for SAR certification of electronic devices, saving SAR certification costs. There is also no need to take additional noise reduction measures on the system side because the antenna is set on the system side, saving the cost of noise reduction on the system side.
[0043] It should be understood that the various forms of processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this disclosure can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions of this disclosure can be achieved, and this document is not limited here.
[0044] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout the present disclosure, "plurality" means two or more, unless otherwise specifically defined.
[0045] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
