Abstract
Description
[Technical Field]
[0001] This invention relates to an electronic device and antenna assembly, particularly an electronic device and antenna assembly in which an antenna is housed in a housing sealed by a cover plate. [Background Technology]
[0002] Most current electronic devices still use antennas based on fourth-generation mobile communication technology (4G). Because 4G antennas do not require a power supply, their waterproofing requirements are lower, and they are placed in areas around the device's casing where waterproofing is less effective, thus maintaining the efficiency of signal transmission and reception. With the development of communication technology, the latest generation of mobile communication technology has evolved from fourth-generation to fifth-generation mobile communication technology (5G). 5G features high data transmission rates, reduced latency, energy savings, low cost, increased system capacity, and massive device connectivity, making it an inevitable technology for future electronic devices.
[0003] However, 5G antennas require a power supply, thus necessitating both high waterproofing and excellent signal transmission and reception efficiency compared to 4G antennas. However, 5G antennas cannot be placed within the waterproof area surrounded by the metal components of electronic devices, otherwise the signal will be blocked. Therefore, the adoption of 5G antennas in electronic devices currently faces challenges. [Summary of the Invention]
[0004] The present invention provides an electronic device and antenna assembly to solve the problems encountered by prior art electronic devices in using 5G antennas.
[0005] An embodiment of the present invention discloses an electronic device comprising: a body and an antenna assembly; the body having a waterproof area and a peripheral area, the peripheral area being located around the waterproof area; the antenna assembly being located in the peripheral area, the antenna assembly comprising: a housing, a circuit board, an antenna and a cover plate; the housing having a receiving groove; the circuit board being located in the receiving groove; the antenna being located in the receiving groove and electrically connected to the circuit board; the cover plate being mounted on the housing and closing the receiving groove.
[0006] Another embodiment of the present invention discloses an antenna assembly comprising: a housing, a circuit board, an antenna, and a cover plate; the housing having a receiving groove; the circuit board being located in the receiving groove; the antenna being located in the receiving groove and electrically connected to the circuit board; and the cover plate being mounted on the housing and closing the receiving groove.
[0007] According to the electronic device and antenna assembly disclosed in the above embodiments, the housing's receiving groove is sealed by a cover plate to prevent water or moisture from entering the housing's receiving groove, thereby ensuring the housing's airtightness. Therefore, even if the antenna assembly is located in the peripheral area around the waterproof zone of the device, it still ensures that water or moisture does not easily enter the housing, thus reducing the probability of damage to the antenna and circuit board inside the housing.

[0015] Figure 7 for Figure 6 A schematic diagram of its breakdown. 【Detailed Implementation Methods】
[0016] Please see Figures 1 to 3 As shown, Figure 1 This is a top view schematic diagram of the electronic device disclosed according to the first embodiment of the present invention. Figure 2 for Figure 1 Partial 3D schematic diagram, Figure 3 for Figure 2 A schematic diagram of its breakdown.
[0017] In this embodiment, the electronic device 1 is, for example, the screen or display of a ruggedized laptop or gaming laptop. One side of the electronic device 1 is pivotally connected to an input device, such as a keyboard. However, in other specific embodiments, the electronic device 1 is a mobile phone, a tablet computer, or a mobile electronic device without a keyboard. The electronic device 1 includes a body 10 and an antenna assembly 20. In this embodiment or other embodiments, the electronic device 1 also includes a seal 30 and two fasteners 40.
[0018] Next, please refer to the following: Figures 2 to 5 As shown, Figure 4 for Figure 2 Another perspective on the breakdown diagram, Figure 5 for Figure 2 A cross-sectional view.
[0019] The casing 10 is, for example, the screen housing of a laptop computer. The casing 10 has a waterproof area 11 and a peripheral area 12. The waterproof area 11 is formed, for example, by a metal plate surrounding it. The peripheral area 12 is located around the waterproof area 11, and its outer surface is covered by a plastic shell. That is, the peripheral area 12 is outside the area formed by the metal plate, making its waterproof effect less than that of the waterproof area 11, and the signal shielding effect on electronic components within the peripheral area 12 less severe than that within the waterproof area 11. Therefore, the waterproof area 11 is used to house electronic components requiring waterproofing or electromagnetic interference protection, such as the motherboard. The peripheral area 12 is used to house electronic components with low waterproofing requirements or those requiring wireless signal transmission and reception.
[0020] The antenna assembly 20 includes a housing 21, a circuit board 22, an antenna 23, and a cover plate 24. The housing 21 is, for example, made of a thermally conductive material and has a receiving groove 211. The receiving groove 211 has a first receiving section 2111 and a second receiving section 2112. The depth D1 of the first receiving section 2111 is greater than the depth D2 of the second receiving section 2112. The circuit board 22 and the antenna 23 are, for example, attached to the housing 21 by double-sided adhesive tapes 25 and 26 and respectively fixed to the first receiving section 2111 and the second receiving section 2112. The antenna 23 is, for example, a 5G antenna. The antenna 23 is electrically connected to the circuit board 22 and thermally coupled to the housing 21. The heat generated by the antenna 23 is conducted to the body 10 through the housing 21, and the body 10 exchanges heat with the outside environment. The cover plate 24 is, for example, Mylar and is made of a transparent material. The cover plate 24 is fixed to the housing 21 by means of adhesive, thereby sealing the receiving groove 211 of the housing 21. This prevents water or moisture from entering the receiving groove 211 from outside the housing 21.
[0021] In this embodiment, the transparent material of the cover plate 24 allows visual inspection of the components inside the housing 21 (such as the circuit board 22 and antenna 23) to determine whether the assembly of these components is correct. Furthermore, the arrangement of fixing the antenna 23 and circuit board 22 to the housing 21 with double-sided adhesive, and fixing the cover plate 24 to the housing 21 by adhesive, facilitates the removal of the cover plate 24, circuit board 22, and antenna 23 from the housing 21 when an assembly error is found. During reassembly, only the double-sided adhesive fixing the circuit board 22 and antenna 23 and the adhesive fixing the cover plate 24 need to be rearranged, thus fixing the circuit board 22, antenna 23, and cover plate 24, thereby reducing the cost of correcting assembly errors in the circuit board 22 and antenna 23.
[0022] In this embodiment, the circuit board 22 has a power connector 221, and the housing 21 also has a through hole 212. The through hole 212 communicates with the first receiving section 2111 of the receiving groove 211 of the housing 21. The seal 30 is, for example, rubber, and the seal 30 has a through hole 31. The through hole 31 is used for the power cable to pass through, so that the power cable engages with the power connector 221 of the circuit board 22.
[0023] In this embodiment, the peripheral region 12 of the body 10 has two assembly structures 121, and the housing 21 of the antenna assembly 20 also has two assembly parts 213. The two assembly parts 213 of the housing 21 are located on opposite sides of the receiving groove 211. The two assembly structures 121 have, for example, two screw holes 1211, and each of the two assembly parts 213 has a through hole 2131. The two fasteners 40 are, for example, screws. The two fasteners 40 are respectively passed through the two through holes 2131 and screwed into the two screw holes 1211, thereby fixing the antenna assembly 20 to the peripheral region 12 of the body 10.
[0024] In this embodiment, the receiving groove 211 of the housing 21 is sealed by the cover plate 24 to prevent water or moisture from entering the receiving groove 211 of the housing 21, thus ensuring the airtightness of the housing 21. Therefore, even though the antenna assembly 20 is located in the peripheral area 12 around the waterproof area 11 of the body 10, it is still ensured that water or moisture does not easily enter the housing 21, thereby reducing the probability of damage to the antenna 23 and circuit board 22 inside the housing 21.
[0025] Furthermore, in this embodiment, the gap between the perforation 31 of the seal 30 and the power cord is filled with waterproof adhesive to prevent water or moisture from entering the receiving groove 211 of the housing 21 through the gap between the perforation 31 and the power cord, thereby further ensuring the sealing performance of the housing 21. However, the fact that the seal 30 is made of rubber is not intended to limit the invention. In other embodiments, the seal is made of waterproof adhesive.
[0026] In this embodiment, the height of the two-assembly structure 121 of the peripheral area 12 of the body 10 is adjusted according to actual needs to adjust the position of the antenna assembly 20 so that the antenna assembly 20 is suitable for electronic devices of different models.
[0027] Next, please refer to Figure 6 and Figure 7 As shown, Figure 6 This is a partial perspective view of the electronic device disclosed in the second embodiment of the present invention. Figure 7 for Figure 6 A schematic diagram of its breakdown.
[0028] In this embodiment, the electronic device 1a is similar to Figure 1 The following description will focus on electronic device 1a and electronic device 1a. Figure 1 The differences between the electronic devices 1 and those that are the same or similar will not be described in detail.
[0029] In this embodiment, the two-assembly structure 121a of the peripheral region 12a of the body 10a has a slope 1212a. Thus, after the two assembly portions 213a of the housing 21a of the antenna assembly 20a are respectively stacked and fixed to the slope 1212a of the two-assembly structure 121a, the signal transmission and reception angle of the antenna 23a is compared to... Figure 1 The signal transmission and reception angles of the antenna 23 are different to meet different usage requirements. However, the two-assembly structure 121a of the peripheral region 12a of the body 10a is not limited to having a slope. In other embodiments, the surface on which the assembly parts of the housing are stacked in the assembly structure of the peripheral region of the body is a horizontal surface. In this configuration, when the portion between the two assembly parts of the housing is twisted relative to the two assembly parts at an angle, so that the two assembly parts of the housing are stacked and fixed on the horizontal surface of the two-assembly structure, the signal transmission and reception angle of the antenna is also different compared to the previous configuration. Figure 1 The signal transmission and reception angles of antenna 23 are different.
[0030] In the above embodiments, the antenna assembly housing has two assembly parts, but is not limited thereto. In other embodiments, the antenna assembly housing has only one assembly part. In this way, the antenna assembly housing can be fixed to the peripheral area of the body with only one fastener.
[0031] Furthermore, in the above embodiments, the casing is exemplified by the main body of a laptop computer, but this is not a limitation. In other embodiments, the casing is the main body of a laptop computer.
[0032] According to the electronic device and antenna assembly disclosed in the above embodiments, the housing's receiving groove is sealed by a cover plate, preventing water or moisture from entering the housing's receiving groove and ensuring the housing's airtightness. Therefore, even if the antenna assembly is located in the peripheral area around the waterproof zone of the device, it still ensures that water or moisture does not easily enter the housing, thereby reducing the probability of damage to the antenna and circuit board inside the housing.
[0033] Although the present invention has been disclosed above with reference to the preferred embodiments described above, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the claims defined in the appended patent application.
