Description

Technical Field

[0001] The utility model relates to the technical field of computer networks, in particular to a router. Background Art

[0002] A router, also known as a gateway device, is used to connect multiple logically separate networks. A so-called logical network represents a single network or a subnet. When data is transmitted from one subnet to another, the routing function of the router can be used to complete it. Routers usually run 24 hours a day, and a large amount of heat is generated during their operation. Especially for the chip, the heat generation is the largest. If this heat cannot be dissipated in time, it will affect the normal operation of the router.

[0003] In the existing routers, heat dissipation fins are installed near the main components of the router to increase the heat dissipation area and improve the heat transfer efficiency. The heat dissipation fins are usually made of metal materials, such as aluminum heat dissipation fins, which can quickly dissipate the heat generated by the components into the surrounding air.

[0004] Although this technology can dissipate heat from the router and reduce the power consumption of the router, during the actual operation of the router, all the components on the entire PCB board are running. Not only the components with high power consumption generate heat, but some other components also generate heat. The heat accumulated by many components cannot be dissipated in time, resulting in problems such as disconnection or frequency reduction when the router is used for a long time.

[0005] Therefore, the above technical problems need to be solved. Summary of the Utility Model

[0006] In order to overcome the deficiencies of the prior art, the utility model provides a router, aiming to solve the technical problems that in the existing routers, due to the working duration, the power consumption of the components generates heat, and the existing routers only set radiators on the components with high power consumption, resulting in poor heat dissipation effect.

[0007] In order to solve the above technical problems, the basic technical solution proposed by the utility model is as follows:

[0008] A router includes a housing, and a PCB board and a heat dissipation member are arranged in the housing. A plurality of heat generating parts are arranged on the PCB board;

[0009] Since the heights of the heat generating parts are different, the heat dissipation member is in close contact with each heat generating part, and the heat dissipation member covers the PCB board and is parallel to the PCB board in the longitudinal direction.

[0010] Furthermore, the heat generating part is in contact connection with the heat dissipation member through a heat conduction medium;

[0011] After each of the heating parts is combined with the heat-conducting medium, the heights of each of the heating parts are equal.

[0012] Furthermore, the heat sink has mounting holes;

[0013] The mounting holes are arranged corresponding to the special-shaped components on the PCB board, and the special-shaped components are exposed from the mounting holes.

[0014] Furthermore, the heat sink has guiding holes;

[0015] The other side of the heat sink facing away from the PCB board has a built-in antenna;

[0016] The guiding holes are used to guide the connecting wires extending from the PCB board to the built-in antenna.

[0017] Furthermore, the heat sink also has fixing holes;

[0018] The fixing holes are used to assemble the built-in antenna.

[0019] Furthermore, the PCB board has a control unit;

[0020] The control unit is electrically connected to a first functional unit and a second functional unit;

[0021] The first functional unit and the second functional unit do not work simultaneously and can be arbitrarily switched under the control of the control unit.

[0022] Furthermore, a power management module is also provided in the housing; the power management module is electrically connected to the PCB board.

[0023] Furthermore, a WPS button is also included;

[0024] One end of the WPS button is exposed on the surface of the housing, and the other end of the WPS is arranged inside the housing and connected to the PCB board.

[0025] Furthermore, a reset button is also included;

[0026] One end of the reset button is exposed outside the housing, and the other end of the reset button is arranged inside the housing and connected to the PCB board.

[0027] Furthermore, a multimedia processor is also included; the multimedia processor is connected to the PCB board.

[0028] The beneficial effects of the present utility model are:

[0029] A router provided by this technical solution includes a housing. There is a PCB board and a heat sink inside the housing. There are several heat-generating parts on the PCB board. Since the heights of the heat-generating parts are different, the heat sink is in close contact with each heat-generating part. The heat sink covers the PCB board and is parallel to the PCB board in the longitudinal direction. Since the heat sink covers the entire PCB board, during the operation of the entire PCB board, the heat generated by each heat-generating part with different heights can be conducted to the surface of the heat sink, and then the heat on the surface of the heat sink is taken away through the convection effect of air, thereby realizing the heat dissipation of the entire PCB board, so as to solve the technical problem that in the prior art, radiators are only provided on components with high power consumption in the router, and the overall heat dissipation effect is not good.

Detailed Embodiment

[0035] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely in conjunction with the attached Figure 1 to the attached Figure 3 The technical solutions in the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0036] A router, also known as a gateway device, is used to connect multiple logically separate networks. A logical network represents either a single network or a subnet. When data is transmitted from one subnet to another, the routing function of the router can be used to complete the transfer. Therefore, a router has the functions of judging network addresses and selecting IP paths. It can establish flexible connections in a multi-network interconnection environment and connect various subnets using completely different data packets and media access methods. A router only accepts information from the source station or other routers and is an interconnection device at the network layer.

[0037] Routers usually run 24 hours a day, and a large amount of heat is generated during their operation. In particular, the chips generate the most heat. If this heat cannot be dissipated in time, it will affect the normal operation of the router.

[0038] The heat dissipation of the router mainly relies on the radiator. However, currently, the radiators applied to routers are only locally arranged on components with high power consumption, and there is generally a problem of poor heat dissipation effect, and the heat of the entire functional module cannot be quickly dissipated in time. Therefore, it is necessary to improve the current router radiator.

[0039] The inventor provides a router, aiming to solve the problem that the existing routers only dissipate heat for local components, resulting in poor heat dissipation effect for the entire functional module as a whole.

[0040] Specifically, as Figures 1 to 3 shown, a router of the present technical solution includes a housing 1. The housing 1 has a PCB board 11 and a heat dissipation member 12 inside. The heat dissipation member 12 is made of a metal material with good thermal conductivity, such as copper, aluminum, etc. The housing 1 also has a built-in antenna 13 and a multimedia processor 14 inside. Among them, the multimedia processor 14 is the chip MT7976CN.

[0041] Among them, the PCB board 11 has a chip MT7981B, which is used to process the various operating tasks of the router. The PCB board 11 has several heat generating parts 111. The heights of the several heat generating parts 111 are different, so the heat dissipation member 12 is in close contact with each heat generating part 111. The heat dissipation member 12 covers the PCB board 11 and is parallel to the PCB board 11 in the longitudinal direction.

[0042] The PCB board 11 also has several special-shaped components 112, connection lines 113, a control unit 114, a first functional unit 115, and a second functional unit 116.

[0043] It should be noted that the heating part 111 and the special-shaped component 112 are both components with specific functions. Components with a lower height, high power consumption, and high heat generation are defined as the heating part 111, and components with a higher height, low power consumption, and low heat generation are defined as the special-shaped component 112.

[0044] The connection line 113 is a flexible wire. One end of the connection line 113 is connected to the frequency modulation module 15 connected to the PCB board 11. In this embodiment, the frequency modulation module 15 uses the chip MT7976CN. The other end of the connection line 113 passes through the surface of the heat dissipation part 12 until the built-in antenna 13 and is connected to the built-in antenna 13.

[0045] In addition, the heat dissipation part 12 covers the PCB board 11, and the heat dissipation part 12 is in close contact with the heating part 111.

[0046] It should be understood that such a design is because there are many components and various functional units on the PCB board 11. During the normal operation of the router, the many components and various functional units will generate heat radiation due to power consumption. When the heat accumulated by the heat radiation of the PCB board 11 is too high, problems such as frequency reduction or disconnection of the router will occur. Therefore, the heat dissipation part 12 is covered on the PCB board 11, and the heat of the PCB board 11 is conducted to the heat dissipation part 12 through heat conduction. In this embodiment, the heat dissipation part 12 is covered above the PCB board 11, and the heat dissipation part 12 and the PCB board 11 are fixed by screws. The heat dissipation part 12 is in close contact with the heating part 111, so that the heat generated by the heating part 111 can be conducted to the surface of the heat dissipation part 12 faster.

[0047] Furthermore, one side of the heat dissipation part 12 facing the PCB board 11 has a heat conduction medium 121; the heat conduction medium 121 is arranged corresponding to the heating part 111. It should be noted that the heat conduction medium 121 is some heat-conducting silicone in this embodiment, and other media with the performance of heat-conducting silicone are within the protection scope of the present invention. This heat-conducting silicone plays a role in connecting the heating part 111 and the heat dissipation part 12, so that the heat generated by the heating part 111 can be conducted to the heat dissipation part 12 better.

[0048] For example, in this embodiment, the heating parts 111 have different heights. In order to enable the heating part 111 at a lower position to conduct heat to the heat sink 12 well, the thicker heat-conducting medium 121 is used to fill the lower heating part 111, so that the lower heating part 111 can also be connected to the heat sink 12 through the heat-conducting medium 121 to conduct the heat generated by the heating part 111 to the heat sink 12.

[0049] Furthermore, the heat sink 12 has mounting holes 122 ; the mounting holes 122 are through holes arranged on the heat sink 12 , the mounting holes 122 are arranged corresponding to the special-shaped parts 112 on the PCB board 11 , and the special-shaped parts 112 are exposed from the mounting holes 122 .

[0050] It should be understood that in order to dissipate heat for most components and not excessively occupy the limited space of the housing 1, the distance between the heat sink 12 and the PCB board 11 is limited. For some of the higher-positioned special-shaped components 112, the heat sink 12 will be pressed against, so that the heat sink 12 cannot dissipate heat well. In this regard, the mounting holes 122 are dug on the heat sink 12. The mounting holes 122 are some through holes on the heat sink 12. The shape of the mounting holes 122 is adapted to the outer contour of the special-shaped component 112. For example, the special-shaped component 112 in this embodiment is an inductor, which is generally in the shape of a cuboid, and the mounting holes 122 are rectangular holes. After the special-shaped component 112 is exposed from the mounting holes 122, it is surrounded by the heat sink 12. The heat radiation generated by the special-shaped component 112 can be absorbed by the heat sink 12 to the surface of the heat sink 12, thereby achieving cooling of the special-shaped component 112.

[0051] Furthermore, the heat sink 12 has a guide hole 123; the other side of the heat sink 12 facing away from the PCB board 11 has a built-in antenna 13; the guide hole 123 is used to guide the connecting wire 113 extending from the PCB board 11 to the built-in antenna 13, and the connecting wire 113 and the built-in antenna 13 can have multiple ones according to the actual usage scenario, and the number of the connecting wires 113 and the built-in antenna 13 corresponds one to one.

[0052] It should be understood that in this embodiment, one side of the heat sink 12 faces the PCB board 11, and the other side of the heat sink 12 has the built-in antenna 13. When the PCB board 11 and the heat sink 12 are assembled in the housing 1, the built-in antenna 13 is in the upward direction of the housing 1, so that the built-in antenna 13 can better receive and acquire network signals.

[0053] However, the connecting wire 113 extending from the PCB board 11 is guided to the built-in antenna 13. On the one hand, since the straight-line distance is the shortest, this wiring method enables the connecting wire 113 to be connected to the built-in antenna 13 at the shortest distance; on the other hand, it can also make the wiring neat and tidy, avoiding cumbersome winding and affecting production efficiency.

[0054] Furthermore, the heat sink 12 also has a fixing hole 124 ; the fixing hole 124 is used to assemble the built-in antenna 13 .

[0055] It should be understood that the built-in antenna 13 can be welded to the heat sink 12 through the fixing hole 124. By fixing the built-in antenna 13 on the surface of the heat sink 12, the heat generated by the built-in antenna 13 during operation can be conducted to the heat sink 12, which can effectively prevent the built-in antenna 13 from overheating during operation and causing signal reception or transmission failure.

[0056] In this embodiment, the built-in antenna 13 is arranged in multiple numbers, including two, three, four, six, etc., depending on the actual situation. Preferably, five are used, two of the five built-in antennas 13 are 2.4G antennas, and the other three are 5G antennas. The signal wavelength of the 2.4G frequency band is longer and has better penetration ability. It can pass through obstacles such as walls and furniture relatively easily, and can still maintain a certain signal strength in an environment with many obstacles. For example, in a home environment, even if the router is placed in the living room, the 2.4G signal can better cover the bedroom, bathroom and other locations, especially those areas separated by several walls from the router. For some old devices or devices that do not require high signal strength, such as smart sockets, some smart home sensors, etc., the 2.4G network can meet their basic connection needs.

[0057] The signal frequency of the 5G band is high and the wavelength is short, which can provide higher transmission speed and lower latency. When the signal is not interfered with, faster data download and upload can be achieved, which can meet the application scenarios with high network speed requirements such as high-definition video playback and online games. There is relatively less interference with 5G signals because there are relatively few devices using the 5G band at present. This enables 5G networks to provide more stable and faster connections in some densely populated environments or with many wireless devices. For example, in an office environment, when multiple people use the wireless network at the same time, 5G networks can provide a better network experience for devices that require high-speed transmission, such as laptops, tablets, etc. In addition, multiple antennas work together to transmit and receive signals in different directions at the same time. This enhances the strength of the signal in all directions and reduces the impact of signal attenuation.

[0058] It should also be noted that the configuration of multiple built-in antennas 13 constitutes a MU-MIMO system. With the MU-MIMO system, the device can send data to multiple devices simultaneously or receive data from multiple devices simultaneously.

[0059] Specifically in use, the multimedia processor 14, i.e., the chip MMT7976CN, outputs a 2.4G or 5G network signal under the control of the chip MT7981B on the PCB board 11. Then, the 2.4G or 5G network signal is transmitted from the built-in antenna 13 through the connecting line 113 to meet the connection requirements of corresponding devices. In another usage scenario, the multimedia processor 14 can also output 2.4G and 5G network signals simultaneously to meet the connection requirements of multiple different devices in the same usage environment.

[0060] Furthermore, the PCB board 11 has a control unit 114; the control unit 114 is electrically connected to a first functional unit 115 and a second functional unit 116; the first functional unit 115 and the second functional unit 116 do not work simultaneously and can be arbitrarily switched under the control of the control unit 114.

[0061] It should be noted that when the first functional unit 115 works, it makes the router have rich functions and high integration. It integrates multiple functions such as wireless access, routing, DHCP server, NAT, and security protection. For example, in a small office or home network, when the first functional unit works, it can independently complete the establishment and management of a wireless network without other additional devices.

[0062] When the second functional unit 116 works, the router has relatively single functions and is mainly responsible for receiving and sending wireless signals. In this application scenario, it usually needs to cooperate with a wireless controller (AC), and the AC centrally manages and controls multiple routers with the thin AP functional unit 116 as the main working state.

[0063] In use, the user can remotely control the control unit 114 through a terminal device to switch the router to the first functional unit 115 or the second functional unit 116. This design method is convenient and fast, making the use of the router more flexible and capable of being transformed into the required working mode according to the actual application scenario.

[0064] In order for the terminal device to remotely control the control unit 114 to switch the working mode of the router, the terminal device should establish a signal connection with the router, such as connecting to the router through the 2.4G or 5G network described above, and then establish a connection with the control unit 114, and set the router through the setting information displayed by the router on the display interface of the terminal device.

[0065] Further, a power management module 15 is also provided in the housing 1; the power management module 15 is electrically connected to the chip MT7981B in the PCB board 11. In this embodiment, the power management module 15 is the chip MP8001DS, which can automatically detect whether there is a power supply signal conforming to the IEEE 802.3af standard on the Ethernet cable connected to the router. When accessing the Ethernet network, it will communicate and negotiate with the power supply equipment (PSE) to determine the feasibility and parameters of power supply, such as power supply voltage, current, etc. In addition, it also has overcurrent and overheat protection functions to maintain the normal operation of the router.

[0066] Further, a WPS button 16 is also included; one end of the WPS button 16 is exposed on the surface of the housing 1, and the other end of the WPS button 16 is provided inside the housing 1 and connected to the PCB board 11.

[0067] When in use, press the WPS button 16 on the router, and then start the WPS button 16 connection function on the new device, and the device and the router will automatically perform connection pairing without manually entering the password.

[0068] Further, a reset button 17 is also included; one end of the reset button 17 is exposed outside the housing 1, and the other end of the reset button 17 is provided inside the housing 1 and connected to the PCB board 11.

[0069] It should be understood that this step can be performed when the router has operating errors or troubleshooting problems, etc., by pressing the reset button 17 to restore the router to its factory settings to facilitate re-setting the router.

[0070] For the router described above, the heat dissipation member 12 covers the PCB board 11 and is attached to the heat generating part through the heat conducting medium. While effectively dissipating the heat of the router, it can also save space, making the router more compact and portable. In addition, this router also complies with the next-generation Wi-Fi 6 (IEEE 802.11ax) standard, supports the WPA3 wireless security protocol to ensure network security, and supports multiple functions such as general repeater, multi-SSID, WPS, intelligent QoS, Wi-Fi scheduler, etc.

Therefore, the present utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present utility model should also fall within the protection scope of the claims of the present utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present utility model.
