[0028] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0031] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after the connection remains unchanged. In addition, the directional terms mentioned in the embodiments of the present application, such as "inside", "outside", etc., are only references to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0032] In the description of the embodiments of the present application, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0033] In the related art, with the development of wireless communication technology, multiple antennas are usually required in wireless network extenders to meet the wireless network extender's demand for guaranteed network speed. When the operating frequency bands of multiple antennas are the same, the signal received by the antenna may include the signal sent by another antenna. And this part of the signal is obviously not needed to be received by the wireless network extender, so this part of the signal is an invalid signal for the operation of the antenna. In other words, if multiple antennas with the same operating frequency band work at the same time, there may be an impact between the two antennas, thereby reducing the wireless communication efficiency of the antenna. In addition, in order to be easy to carry, the wireless network extender makes the overall size of the wireless network extender smaller, which makes the mutual interference between multiple antennas more obvious, thereby reducing the performance of the wireless network extender.

[0034] In order to solve the above technical problems, this application provides a wireless network extender. Figure 1 , Figure 1 Schematic diagram of a wireless network extender provided in some embodiments of the present application. The wireless network extender 100 may include a circuit board 1 , a first shielding component 2 , a first antenna 3 and a second antenna 4 .

[0035] Exemplarily, the circuit board 1 may be a PCB (Printed Circuit Board).

[0036] The first shielding assembly 2 may include a shielding cover body 21 and a heat sink 22. The shielding cover body 21 may be disposed on the circuit board 1. The shielding cover body 21 may reduce the impact of external electromagnetic interference on the circuit board 1, and may prevent the components on the circuit board 1 from interfering with the operation of other devices. It may also protect the circuit board 1 and prevent dust and other debris from causing damage or corrosion to the circuit board 1.

[0037] The heat sink 22 can be disposed on one side of the shielding cover body 21. The heat sink 22 can dissipate heat from the circuit board 1, so that the circuit board 1 can be kept at a normal operating temperature, which is beneficial to improving the safety and reliability of the operation of the circuit board 1.

[0038] The first antenna 3 and the second antenna 4 are electrically connected to the circuit board 1. In the first direction parallel to the circuit board 1, the first antenna 3 and the second antenna 4 can be located on opposite sides of the first shielding component 2. Thus, the first shielding component 2 can play an isolating role between the first antenna 3 and the second antenna 4, and can block the radiation signal between the first antenna 3 and the second antenna 4, so that the isolation between the first antenna 3 and the second antenna 4 can be increased, which is beneficial to reduce the mutual interference between the first antenna 3 and the second antenna 4, and further beneficial to improve the performance indicators of the first antenna 3 and the second antenna 4. In addition, the setting of the positions of the first antenna 3 and the second antenna 4 can improve the rationality of the layout of the wireless network extender 100, and can avoid the wireless network extender 100 from being too large.

[0039] Here, "isolation" refers to the ratio of the signal transmitted by one antenna to the signal received by another antenna and the signal of the transmitting antenna.

[0040] It should be noted that the wireless network extender 100 may further include other antennas, and the positions and layouts of the other antennas may refer to the layouts of the first antenna 3 and the second antenna 4 .

[0041] According to the wireless network extender 100 of the embodiment of the present application, by arranging the first antenna 3 and the second antenna 4 on opposite sides of the first shielding component 2 connected to the circuit board 1, the radiation signal between the first antenna 3 and the second antenna 4 can be blocked by the first shielding component 2, so that the isolation between the first antenna 3 and the second antenna 4 can be increased, which is conducive to reducing the mutual interference between the first antenna 3 and the second antenna 4, and further conducive to improving the radiation performance of the wireless network extender 100. In addition, the first antenna 3 and the second antenna 4 can make the layout of the wireless network extender 100 reasonable, which is conducive to the portability of the wireless network extender 100.

[0042] Please continue reading Figure 1In some embodiments, in the first direction, two opposite sides of the circuit board 1 may have a first groove 111 and a second groove 112. The first shielding component 2 may be located between the first groove 111 and the second groove 112. The first antenna 3 is disposed in the first groove 111, and the second antenna 4 is disposed in the second groove 112. Specifically, the first antenna 3 may be disposed in the first groove 111, and the first antenna 3 may be connected to the circuit board 1 from the side of the circuit board 1. The second antenna 4 may be disposed in the second groove 112, and the second antenna 4 may be connected to the circuit board 1 from the side of the circuit board 1. Thus, the structural layout of the wireless network extender 100 can be optimized while ensuring that the first shielding component 2 shields the radiation between the first antenna 3 and the second antenna 4, thereby reducing the volume of the wireless network extender 100, which is beneficial to improving the portability of the wireless network extender 100.

[0043] Exemplarily, the positions of the first groove 111 and the second groove 112 may overlap in the first direction, for example, the first groove 111 and the second groove 112 may face each other in the first direction, or the first groove 111 and the second groove 112 may partially overlap in the first direction. This arrangement can optimize the structural layout of the wireless network extender 100.

[0044] As another example, the positions of the first groove 111 and the second groove 112 may also be staggered in the first direction.

[0045] Please continue reading Figure 1 In some embodiments, the first groove 111 and the second groove 112 may be disposed at the top of the circuit board 1. The “top” refers to the end of the circuit board 1 away from the connector 7. Thus, the first groove 111 and the second groove 112 may form openings at the side and top of the circuit board 1, thereby facilitating the assembly of the first antenna 3 and the second antenna 4, which is beneficial to improving the assembly efficiency of the wireless network extender 100.

[0046] Please continue reading Figure 1In some embodiments, the wireless network extender 100 may further include a second shielding component 5. The circuit board 1 may further include a first portion 11 and a second portion 12. The second portion 12 may be connected to the first portion 11. The first groove 111 and the second groove 112 may be provided on the first portion 11. The second shielding component 5 may be provided on the second portion 12. Specifically, the second portion 12 may extend from the edge of the first portion 11 in a direction away from the first groove 111, and the remaining components connected to the circuit board 1 may be provided on the second portion 12. The second shielding component 5 provided at the same time may also have a shielding and heat dissipation function, thereby shielding and dissipating the heat of the second portion 12. In this way, the use area of ​​the circuit board 1 may be expanded, so that the circuit board 1 may have more space for arranging components, and the design of the circuit board 1 may be more flexible. At the same time, a larger circuit board 1 may also improve the heat dissipation capacity of the circuit board 1, which is conducive to improving the service life of the circuit board 1.

[0047] Please continue reading Figure 1 The first shielding component 2 and the second shielding component 5 are an integral part. Therefore, the connection strength between the first shielding component 2 and the second shielding component 5 can be improved, which is also beneficial to improving the assembly efficiency of the wireless network extender 100.

[0048] Please continue reading Figure 1 In some embodiments, there may be a spacing W between the first antenna 3 and the second antenna 4, and the spacing W is ≥ 20 mm. Specifically, the spacing W between the first antenna 3 and the second antenna 4 may be in the range of 20 mm, 20.5 mm, 21 mm, 21.5 mm, 22 mm, 22.5 mm, 23 mm, 23.5 mm, 24 mm, 24.5 mm or 25 mm, etc. Therefore, by limiting the range of the spacing between the first antenna 3 and the second antenna 4, it is possible to avoid the spacing between the first antenna 3 and the second antenna 4 being too small, so that the first shielding component 2 cannot shield the radiation signal between the first antenna 3 and the second antenna 4, thereby facilitating the radiation performance of the wireless network extender 100.

[0049] The distance W between the first antenna 3 and the second antenna 4 may be the shortest distance between the first antenna 3 and the second antenna 4 .

[0050] Please continue reading Figure 1 In some embodiments, a heat dissipation hole (not shown) may be provided on one side of the shielding cover body 21 away from the circuit board 1, and the heat sink 22 includes heat dissipation fins, which are provided at the heat dissipation holes. The heat dissipation fins can enhance the conduction and dissipation of heat by increasing the surface area. Thus, the heat dissipation efficiency of the circuit board 1 can be improved by the heat dissipation fins, and the service life of the circuit board 1 can be better extended, which is conducive to improving the reliability and stability of the wireless network extender 100.

[0051] Exemplarily, the heat sink 22 may also be thermally conductive silicone.

[0052] Please continue reading Figure 1 In some embodiments, at least one of the first antenna 3 and the second antenna 4 is a PiFa (Planar Inverted F Antenna) antenna. Specifically, the first antenna 3 may be a PiFa antenna, the second antenna 4 may be a PiFa antenna, or both the first antenna 3 and the second antenna 4 may be PiFa antennas. Since the PiFa antenna has a wider operating frequency band and lower design and manufacturing costs, it is beneficial to reduce the use cost of the wireless network extender 100 while ensuring the working performance of the wireless network extender 100.

[0053] Please continue reading Figure 1 In some embodiments, the wireless network extender 100 may further include a connector 7. The connector 7 enables the wireless network extender 100 to be connected to an external power supply device. The connector 7 may be any one of a Type-C interface, a Micro-USB interface, and a Mini-USB interface, which are not specifically limited herein.

[0054] Therefore, the wireless network extender 100 can be used directly through the connector 7 , which is beneficial to improving the convenience of using the wireless network extender 100 .

[0055] Please continue reading Figure 1 The connector 7 can be arranged on a side of the circuit board 1 away from the first antenna 3. This arrangement can reduce the shielding of the first antenna 3 and the second antenna 4 when the wireless network extender 100 is in use, which is conducive to ensuring the working performance of the wireless network extender 100.

[0056] Please continue reading Figure 1 In some embodiments, the wireless network extender 100 may further include an extender body 6. The extender body 6 may have a receiving cavity 61. The circuit board 1, the first shielding component 2, the first antenna 3, and the second antenna 4 may all be disposed in the receiving cavity 61. Thus, the circuit board 1, the first shielding component 2, the first antenna 3, and the second antenna 4 may be protected by the extender body 6, and the influence of dust on the components in the receiving cavity 61 may be reduced.

[0057] Please continue reading Figure 1In some embodiments, a heating element (not shown) may be provided on the circuit board 1, and the shielding cover body 21 is provided to cover the outside of the heating element. Specifically, the heating element may be an electronic component, which includes but is not limited to resistors, capacitors, inductors, potentiometers, electron tubes, connectors, semiconductor discrete devices, electroacoustic devices, laser devices, electronic display devices, optoelectronic devices, sensors, relays, integrated circuit devices, etc., and the electronic components may be electrically connected through the circuit board 1. The shielding cover body 21 may be fixed on the surface of the circuit board 1, and covered on the outside of the heating element. The shielding cover body 21 may be fixed on the surface of the circuit board 1 by welding or bonding.

[0058] In this way, the circuit inside the shielding cover body 21 can be prevented from radiating electromagnetic waves outward, and the electromagnetic waves outside the shielding cover body 21 can be prevented from entering the shielding cover body 21, thereby preventing the electronic components inside the shielding cover body 21 from causing electromagnetic interference to the electronic components outside the shielding cover body 21. At the same time, the heat sink 22 can also directly dissipate the heat of the heating element, which is beneficial to improving the heat dissipation efficiency of the heat sink 22, thereby improving the heat dissipation capacity of the wireless network extender 100.

[0059] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0060] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
