[0003] Wireless access devices include components such as a housing, circuit board, and antenna. The circuit board handles various network protocols and management tasks to ensure the normal operation of the wireless network. The wireless access device has a built-in antenna that amplifies the signals received or transmitted by the device.

[0004] However, the more functions a wireless access device has, the higher its power consumption becomes, leading to increased heat generation on the circuit board. Without a heat dissipation component, the heat dissipation capacity of a wireless access device will be relatively low, impacting its performance. Furthermore, the built-in antenna is obstructed by the casing, reducing the strength and range of the transmitted signal. Summary of the Invention

[0049] Wireless access devices consist of a housing, circuit board, radio frequency module, and antenna. The circuit board handles various network protocols and management tasks to ensure the normal operation of the wireless network. As wireless access devices become more functional, their power consumption and heat generation also increase, and the heat dissipation of the circuit board affects the performance of the wireless access device. To prevent the circuit board from overheating and causing performance degradation or damage to the wireless access device, a heat dissipation module is typically added. This design increases the weight and size of the wireless access device.

[0050] In addition, to enhance signal strength and coverage, wireless access devices can be equipped with external antennas, which can strengthen the received or transmitted signal. However, external antennas reduce the aesthetics of wireless access devices. External antennas are also susceptible to physical damage such as impacts, which can lead to antenna damage or breakage, affecting the normal operation of the device.

[0051] This application provides a wireless access device, including a housing, a circuit board, and an antenna. The housing includes a signal reflector. By reflecting the signal emitted by the antenna through the signal reflector, the signal strength and coverage of the antenna can be improved, thereby enhancing the signal strength and coverage of the wireless access device. Furthermore, the housing has an accommodating space within which the circuit board is disposed. By attaching the signal reflector to the circuit board, heat from the circuit board is conducted to the larger signal reflector for dissipation, thus increasing the heat dissipation area and improving the heat dissipation efficiency of the wireless access device.

[0052] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0053] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0054] Reference Figure 1 As shown in the illustration, the wireless access device 1 of this application embodiment can be applied to various fields such as homes, businesses, and public places. The wireless access device 1 can serve as a transmission medium, providing users with fixed or mobile terminal access services. The wireless access device 1 (e.g., a wireless router or wireless AP) communicates with wireless devices (such as computers, mobile phones, tablets, etc.) through a wired network (such as fiber optic cable) to achieve data transmission and reception.

[0055] The wireless access device 1 may include a circuit board 20. The circuit board 20 can perform signal transmission, data processing, and control functions. The circuit board 20 may include components such as a substrate, resistors, inductors, chips, and radio frequency modules. Resistors, inductors, and chips generate considerable heat during operation, resulting in significant heat generation on the circuit board 20.

[0056] Reference Figure 2 As shown, the wireless access device 1 may include an antenna 30. The antenna 30 is responsible for radiating and receiving radio signals, which can improve the transmission distance and signal strength of the wireless access device 1. The antenna 30 can radiate radio frequency signals from the circuit board 20 and receive radio frequency signals from the external environment.

[0057] Antenna 30 may include omnidirectional antennas and directional antennas. An omnidirectional antenna exhibits similar radiation and reception capabilities in all directions on the horizontal plane, meaning it displays omnidirectional or near-omnidirectional radiation characteristics on the horizontal plane. A directional antenna has high radiation and reception capabilities in a specific direction, while its radiation is relatively weak or almost nonexistent in other directions. This type of antenna is suitable for scenarios requiring long-distance communication or interference suppression, such as radar, satellite communication, and base stations.

[0058] The wireless access device 1 may include a housing 10. The housing 10 can protect the internal components of the wireless access device 1, such as the circuit board 20 and the antenna 30, from physical damage (such as impact), ensuring stable operation of the device over a long period of time.

[0059] Reference Figure 3 As shown, a receiving space 110 is further formed inside the housing 10. The antenna 30 and the circuit board 20 are disposed within the receiving space 110. The antenna 30 and the circuit board 20 can be fixed and installed within the receiving space 110. This ensures the stability and reliability of the connection between the antenna 30 and the circuit board 20.

[0060] The housing 10 includes a signal reflector 120. The signal reflector 120 may be part of the housing 10. The signal reflector 120, or a portion thereof, may be used to reflect signals (such as electromagnetic waves). The surface of the signal reflector 120 facing the receiving space 110 is defined as the first surface of the signal reflector 120. A distance may be provided between the signal reflector 120 and the antenna 30, which allows adjustment of the signal reflection effect of the signal reflector 120 to meet the needs of different frequency band signals.

[0061] For example, the signal reflector 120 can be made of metal. Metal can reflect wireless signals, reducing signal loss. Furthermore, metal has high strength, which helps protect the antenna 30 and circuit board 20 inside the housing space 110.

[0062] For example, the signal reflector 120 can be made of glass, and applying a reflective coating to the surface of the glass can enhance signal strength. Compared to metal, glass is lighter, which helps to reduce the overall weight of the wireless access device 1.

[0063] When the antenna 30 is working, it can emit signals to the surrounding area. Some of the signals are emitted toward the signal reflector 120, and some of the signals are reflected back by the signal reflector 120 due to its reflection characteristics. This can enhance the signal in the area on the side where the antenna 30 is located, thereby enhancing the signal strength and coverage of the wireless access device 1.

[0064] Furthermore, the circuit board 20 is attached to the first surface of the signal reflector 120. When the circuit board 20 is operating, the heat generated by the circuit board 20 is transferred to the signal reflector 120 via thermal conduction. The signal reflector 120, as part of the housing 10, radiates the heat into the air. The signal reflector 120 has a large area, increasing the heat dissipation area and thus improving the heat dissipation efficiency of the circuit board 20, thereby improving the heat dissipation efficiency of the wireless access device 1.

[0065] Therefore, the wireless access device 1 provided in this application embodiment includes a signal reflector 120 in its housing 10. The signal reflector 120 reflects the signal emitted by the antenna 30, increasing the antenna signal gain and enhancing the signal strength and coverage of the wireless access device 1. Furthermore, by attaching the signal reflector 120 to the circuit board 20, the heat from the circuit board 20 is dissipated through the larger area of ​​the signal reflector 120, thereby increasing the heat dissipation area and improving the heat dissipation efficiency of the wireless access device 1.

[0066] In some embodiments, the portion of the signal reflector 120 used for reflecting the signal from the antenna 30 and the portion of the signal reflector 120 used for heat dissipation by attaching to the circuit board 20 can be made of the same material.

[0067] In some embodiments, the signal reflector 120 can be made of metal. The conductivity of the metal material allows the signal reflector 120 to reflect the wireless signal emitted by the antenna 30 more efficiently, reducing signal loss and increasing signal gain. Simultaneously, the good thermal conductivity of the metal material helps to quickly conduct heat generated on the circuit board 20 to the signal reflector 120, improving the heat dissipation performance of the wireless access device 1. Furthermore, making the signal reflector 120 of metal can reduce the impact of external electromagnetic interference on the internal circuitry of the wireless access device 1, improving the reliability of the wireless access device 1.

[0068] Specifically, the signal reflector 120 can be made of aluminum alloy. Aluminum alloy has good electrical conductivity, which can efficiently reflect the wireless signal emitted by the antenna 30, reducing signal loss and improving signal strength and coverage. Aluminum alloy has excellent thermal conductivity, which can quickly conduct the heat generated by the circuit board 20 to the signal reflector 120, helping to dissipate heat from the wireless access device 1. Furthermore, a dense oxide film easily forms on the surface of the aluminum alloy, which has good corrosion resistance, protecting the signal reflector 120 from environmental corrosion and extending the lifespan of the wireless access device 1.

[0069] In some embodiments, the portion of the signal reflector 120 used for reflecting the signal from the antenna 30 and the portion of the signal reflector 120 used for attaching to the circuit board 20 for heat dissipation may be made of different materials.

[0070] For example, the strongest signal is emitted by the area where the antenna 30 projects onto the signal reflector 120. The signal reflector 120 can be made of glass, and a reflective coating can be added to the surface of a portion of the area where the antenna 30 projects onto the signal reflector to meet the requirements of enhancing signal strength and heat dissipation.

[0071] In some embodiments, the area on the signal reflector 120 where the antenna 30 is orthographically projected onto the signal reflector 120 is made of glass material with a surface coated with a metal film. Signals emitted by the antenna 30 toward this area are reflected by the metal film, increasing the signal strength and coverage directly in front of the antenna 30, thereby improving the signal strength and coverage of the wireless access device 1. The circuit board 20 is attached to the surface of the signal reflector 120. A portion of the signal reflector 120 used for heat dissipation by attaching the circuit board 20 can be made of metal. Heat generated by the circuit board 20 is transferred to the signal reflector 120 through thermal conduction. Since the signal reflector 120 has a large area, increasing the heat dissipation area improves the heat dissipation efficiency of the circuit board 20, thus improving the heat dissipation efficiency of the wireless access device 1.

[0072] In addition, the signal reflector 120 can also be used to fix the wireless access device 1. For example, one or more mounting holes are machined in the signal reflector 120, through which the wireless access device 1 is fixed to the device or wall.

[0073] In some embodiments, the signal reflector 120 is provided with a mounting port 121 through which optical fibers, cables and connecting devices of the external network can be connected to the internal components of the wireless access device 1.

[0074] For example, the mounting port 121 can be set to an 86×86mm size port. This size of mounting port 121 is a commonly used interface standard, which can improve the compatibility with external network optical fibers, cables and connection devices, and make the application range of wireless access device 1 more extensive.

[0075] Reference Figure 4 As shown, in addition to the signal reflector 120, the housing 10 may include a main body 130. A receiving space 110 is formed by the main body 130 to mount components such as the circuit board 20. The main body 130 has a first opening 131 and a second opening 132, which are the two end ports of the main body 130. That is, both the first opening 131 and the second opening 132 are connected to the receiving space 110. Components such as the circuit board 20 can be mounted into the receiving space 110 through the first opening 131 and the second opening 132.

[0076] The signal reflector 120 covers the second opening 132 to enclose the receiving space 110. By separating the signal reflector 120 from the main body 130, the manufacturing difficulty of the signal reflector 120 and the main body 130 can be reduced. In this case, the signal reflector 120 and the main body 130 are made of different materials, reducing the cost of the wireless access device 1.

[0077] For example, the signal reflector 120 is made of metal, and the main body 130 is made of plastic. Making the main body 130 of plastic reduces the cost of the wireless access device 1. Furthermore, the main body 130 can be manufactured into a complex structure using processes such as injection molding.

[0078] Specifically, the signal reflector 120 is connected to the main body 130 by fasteners so that the signal reflector 120 covers the second opening 132.

[0079] The housing 10 also includes a cover plate 140. The cover plate 140 covers the first opening 131 to close the receiving space 110. By separating the cover plate 140 from the main body 130, it is convenient to install components such as the circuit board 20 through the first opening 131.

[0080] For example, the cover plate 140 is made of plastic material, which can reduce the cost of the wireless access device 1. The cover plate 140 is disposed opposite to the signal reflector 120. After being reflected by the signal reflector 120, part of the signal propagates towards the cover plate 140. The use of plastic material for the cover plate 140 can reduce signal reflection and avoid reducing signal strength and coverage.

[0081] Specifically, the cover plate 140 and the main body 130 can be connected by snap-fit, so that the cover plate 140 covers the first opening 131. This facilitates the installation of the cover plate 140 and improves the assembly efficiency of the cover plate 140 and the main body 130.

[0082] The cover plate 140 is disposed opposite to the signal reflector 120. That is, the cover plate 140 and the signal reflector 120 are disposed on both sides of the main body 130. This facilitates the installation and maintenance of components such as the circuit board 20 through the first opening 131 and the second opening 132.

[0083] Reference Figure 5 As shown, to improve the space utilization of the accommodating space 110, a partition 134 is provided inside the main body 130. The partition 134 divides the accommodating space 110 into a first chamber 111 and a second chamber 112. The first chamber 111 and the second chamber 112 can be arranged according to the characteristics of different devices (such as size, power consumption, electromagnetic compatibility, etc.). This avoids mutual interference between devices and improves the reliability of the wireless access device 1.

[0084] The partition 134 may be provided with a communication port 1341 so that the first chamber 111 can communicate with the second chamber 112.

[0085] In some embodiments, the wireless access device 1 may include a power adapter (not shown). The power adapter converts external power into the current and voltage required by the circuit board 20, providing a stable power supply to the wireless access device 1. The power adapter may have functions such as overvoltage protection and overcurrent protection.

[0086] The first chamber 111 can be used to install devices such as power adapters, optical fibers, cables, and optical fiber protection boxes, thereby improving the applicability of the wireless access device 1.

[0087] The first chamber 111 communicates with the outside of the wireless access device 1 via a mounting port 121. The power adapter has a connection end exposed through the mounting port 121 and connected to an external interface of the wireless access device 1. This avoids exposing the power adapter to the outside of the wireless access device 1, improving its overall aesthetics. For example, the power adapter's connection end can be connected to a socket via the mounting port 121 to provide power to the wireless access device 1.

[0088] The antenna 30 is placed inside the first chamber 111, and the circuit board 20 is located inside the second chamber 112. This avoids electromagnetic interference between the antenna 30 and the circuit board 20, which could affect the signal transmitted by the antenna 30. This also allows for meeting the different needs of the antenna 30 and the circuit board 20. For example, since the circuit board 20 is located inside the second chamber 112, the heat dissipation structure of the second chamber 112 can be designed according to heat dissipation requirements.

[0089] Furthermore, the antenna 30 can be mounted on the side wall inside the first chamber 111 to avoid occupying too much space in the first chamber 111. This can reduce the size of the wireless access device 1.

[0090] In some embodiments, the first chamber 111 is provided with a plurality of antennas 30 to improve the signal strength and coverage of the wireless access device 1.

[0091] In some embodiments, antennas 30 are respectively provided on the side walls on both sides of the first chamber 111. For example, the wireless access device 1 is fixed to the wall at the entrance of the room by a signal reflector 120. The antennas 30 emit signals to the surroundings. The signals are reflected by the signal reflector 120, which improves the signal strength and coverage in the room.

[0092] Reference Figure 6As shown, in some embodiments, the main body 130 is provided with multiple heat dissipation holes 133. When the circuit board 20 and other devices are operating, the circuit board 20 and other devices dissipate some heat into the housing space 110. The housing space 110 is connected to the outside of the housing 10 through the heat dissipation holes 133, dissipating some of the heat dissipated by the circuit board 20 and other devices to the outside of the housing 10 through natural convection or forced convection (such as natural wind). This can reduce the internal temperature of the wireless access device 1, prevent the circuit board 20 from overheating and causing performance degradation or damage, and improve the heat dissipation efficiency of the wireless access device 1.

[0093] The multiple heat dissipation holes 133, depending on their location, include a first heat dissipation hole 1331 and a second heat dissipation hole 1332. The first heat dissipation hole 1331 is connected to the first chamber 111, and the heat of the first chamber 111 can be dissipated to the outside of the housing 10 through natural thermal convection, thereby improving the heat dissipation efficiency of the wireless access device 1.

[0094] Similarly, by connecting the second heat dissipation hole 1332 to the second chamber 112, the heat of the second chamber 112 can be dissipated to the outside of the housing 10 through natural heat convection or forced convection (such as natural wind), thereby improving the heat dissipation efficiency of the wireless access device 1.

[0095] As mentioned above, the partition 134 is provided with a connecting port 1341, through which the first chamber 111 communicates with the second chamber 112. The connecting port 1341 can be configured as a grid to connect the first chamber 111 and the second chamber 112, which improves the aesthetics of the connecting port. The connecting port 1341 can balance the heat distribution between the two chambers, allowing heat transfer between them. This allows heat to be dissipated from the chamber with higher heat to the chamber with lower heat, and then dissipated through the heat dissipation holes of the chamber with lower heat, thereby increasing the heat dissipation pathways. The partition 134 is provided with multiple parallel connecting ports 1341 to allow for faster heat flow between the first chamber 111 and the second chamber 112. For example, the connecting port 1341 and the partition 134 can also be integrally formed, improving the production efficiency of the main body 130.

[0096] In some embodiments, the wireless access device 1 is installed vertically, with the first chamber 111 located above the second chamber 112. In this case, a first heat dissipation hole 1331 is provided on the side wall of the first chamber 111 of the main body 130, and a second heat dissipation hole 1332 is provided at the bottom of the second chamber 112. The hot air in the second chamber 112, being less dense, rises, causing cool air to enter the housing 10 from the outside through the second heat dissipation hole 1332. Then, the rising hot air can reach the first chamber 111 from the second chamber 112 through the connecting port 1341, and then dissipate to the outside of the housing 10 through the first heat dissipation hole 1331 of the first chamber 111, thus forming natural convection. This arrangement makes it easier for the hot air of the wireless access device 1 to rise and escape, improving the heat dissipation efficiency of the wireless access device 1.

[0097] Reference Figure 5 As shown, factors such as the bending radius, connection method, and fiber length of an optical fiber affect its transmission performance. During fiber optic cabling, it is necessary to ensure that the bending radius of the fiber is not less than its minimum bending radius to avoid fiber bending, which could lead to signal attenuation or loss. Therefore, the main body 130 is equipped with multiple guide posts 135, the outer sides of which are used to wrap the optical fiber connected to the circuit board 20. Wrapping the optical fiber on the outer sides of the guide posts 135 reduces interference and mutual compression between fibers, ensuring neatness and orderliness, and making the cabling process more standardized.

[0098] Multiple guide posts 135 are arranged around the mounting port 121, and optical fibers are arranged around the outer area of ​​the mounting port 121. Other devices can be set in the area of ​​the mounting port 121, improving the utilization rate of the accommodating space 110.

[0099] Specifically, the main body 130 may be provided with four guide posts 135. The top of the guide post 135 is provided with a bent extension 1351 that extends away from the mounting port 121. The extension 1351 can prevent the optical fiber from coming off the guide post 135, causing the optical fiber to bend and be damaged.

[0100] The wireless access device 1 provided in this application embodiment divides a receiving space 110 into a first chamber 111 and a second chamber 112. The second chamber 112 can fix the circuit board 20 and the power adapter. A guide post 135 is provided in the first chamber 111 for laying optical fibers. This configuration can improve the integration of the wireless access device 1, improve the assembly efficiency of the wireless access device 1, and reduce the manufacturing cost of the wireless access device 1.

[0101] Reference Figure 7 As shown, the main body 130 is provided with a fixing part 136, which is used to fix the circuit board 20 to ensure that the circuit board 20 remains stable during equipment operation and to prevent it from loosening due to vibration or external force.

[0102] Specifically, the fixing part 136 is provided with a plurality of support columns 1361. The support columns 1361 are machined with threaded holes. Fasteners (such as screws) are screwed into the support columns 1361 through the circuit board 20 to fix the circuit board 20 to the fixing part 136.

[0103] The fixing part 136 is spaced apart from the signal reflector 120. That is, there is a distance between the fixing part 136 and the signal reflector 120. The space between the fixing part 136 and the signal reflector 120 is used to mount the circuit board 20. When maintaining the device through the first opening 131, the fixing part 136 can protect the circuit board 20 from impacts.

[0104] The circuit board 20 is installed into the second chamber 112 through the second opening 132 and is fixedly connected to the fixing part 136.

[0105] In some embodiments, components such as resistors and chips that generate a lot of heat on the circuit board 20 are placed on the side of the circuit board 20 away from the fixing part 136. By attaching the surface of the circuit board 20 with the components that generate a lot of heat to the signal reflector 120, a large amount of heat is conducted to the signal reflector 120. The signal reflector 120 is larger than the size of the circuit board, increasing the heat dissipation area and thus improving the heat dissipation efficiency of the wireless access device 1.

[0106] Reference Figure 8 As shown, the signal reflector 120 is provided with one or more contact portions 122. The contact portions 122 are attached to the circuit board 20, transferring heat from the circuit board 20 to the contact portions 122 through thermal conduction. The heat from the contact portions 122 is then quickly transferred to the entire signal reflector 120, thereby increasing the heat dissipation area and improving the heat dissipation efficiency of the wireless access device 1. For example, components on the circuit board 20 that generate a lot of heat, such as resistors and chips, can be attached to the contact portions 122 to improve the heat dissipation efficiency of the wireless access device 1.

[0107] The circuit board 20 houses components that generate significant heat, as well as other components (such as an RF module). These other components may be taller than the heat-generating components. If the entire signal reflector 120 is flat, it might touch the taller components first when it is attached to the circuit board 20, preventing the heat-generating components from properly attaching to the signal reflector 120. Therefore, the signal reflector 120 can be provided with a contact portion 122 that protrudes towards the circuit board 20, allowing it to contact and attach with the heat-generating components.

[0108] When the signal reflector 120 is made of metal, the contact portion 122 can be processed by stamping the signal reflector 120 to improve the processing efficiency of the signal reflector 120 and reduce the processing cost of the signal reflector 120.

[0109] In some embodiments, a thermally conductive layer is provided between the surface of the circuit board 20 and the contact surface of the signal reflector 120 to improve the thermal conductivity between the surface of the circuit board 20 and the signal reflector 120.

[0110] For example, the thermally conductive layer can be made of materials such as thermally conductive adhesive or thermally conductive grease. Materials such as thermally conductive adhesive and thermally conductive grease have good thermal conductivity and adhesion, which can bond the circuit board 20 and the signal reflector 120 together and provide a stable heat conduction path.

[0111] For example, the thermally conductive layer can be set as a thermally conductive silicone pad. The thermally conductive silicone pad usually has a certain elasticity and thickness, which can fill the uneven area between the circuit board 20 and the signal reflector 120, ensuring close contact between the two and providing stable thermal conductivity.
