All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present disclosure.

Referring to fig. 1, fig. 1 is a schematic view of an application environment of a network device according to an embodiment of the present disclosure. The network device 1 is a Customer Premises Equipment (CPE). The network device 1 communicates with the base station 3, receives a first network signal sent by the base station 3, and converts the first network signal into a second network signal. The second network signal can be used by terminal equipment 5 such as a tablet computer, a smart phone, a notebook computer and the like. The first network signal may be, but is not limited to, a fifth generation mobile communication technology (5G) signal, and the second network signal may be, but is not limited to, a Wireless Fidelity (WiFi) signal. The CPE can be widely applied to rural areas, towns, hospitals, factories, cells and the like, and the first network signals which can be accessed by the CPE can be wireless network signals, so that the cost of laying a line network can be saved.

Referring to fig. 2, fig. 3 and fig. 4 together, fig. 2 is a schematic structural diagram of a network device according to an embodiment of the present application; FIG. 3 is a schematic diagram of the network device of FIG. 2 with the housing removed; fig. 4 is a circuit block diagram of a network device according to another embodiment of the present application. The network device 1 comprises a housing 220. The housing 220 may be in the shape of a multi-sided cylindrical barrel, or a cylindrical barrel. The material of the housing 220 may be, but is not limited to, an insulating material such as plastic. It is understood that in other embodiments, the network device 1 may not include the housing 220.

The network device 1 further comprises a first signal receiving antenna 110 and a signal conversion device 120. The first signal receiving antenna 110 is rotatable to receive the first network signals from different directions, and the signal conversion device 120 converts the first network signal with the strongest signal from the first network signals received by the first signal receiving antenna 110 from different directions into the second network signal.

When the network device 1 includes a housing 220, the first signal receiving antenna 110 and the signal conversion apparatus 120 may be disposed in the housing 110.

The first signal receiving antenna 110 may be, but is not limited to, a millimeter wave signal receiving antenna or a terahertz signal receiving antenna. Accordingly, the first network signal may be, but is not limited to, a millimeter wave signal or a terahertz signal. Currently, in the fifth generation mobile communication technology (5th generation wireless systems, 5G), according to the specification of the 3gpp ts 38.101 protocol, a New Radio (NR) of 5G mainly uses two sections of frequencies: FR1 frequency band and FR2 frequency band. Wherein, the frequency range of the FR1 frequency band is 450 MHz-6 GHz, also called sub-6GHz frequency band; the frequency range of the FR2 frequency band is 24.25 GHz-52.6 GHz, and belongs to the millimeter Wave (mm Wave) frequency band. The 3GPP Release 15 specification specifies that the current 5G millimeter wave frequency band includes: n257(26.5 to 29.5GHz), n258(24.25 to 27.5GHz), n261(27.5 to 28.35GHz) and n260(37 to 40 GHz). Millimeter wave or terahertz signal have transmission speed advantage such as fast, however, millimeter wave or terahertz signal are sheltered from by external object easily. When there is an object block between the first signal receiving antenna 110 and the base station 3, the signal strength of the first network signal received by the first signal receiving antenna 110 is weak, and at this time, if the first network signal with weak signal strength is converted into the second network signal, the signal strength of the obtained second network signal may also be weak.

For the network device 1 placed at a certain position, the signal strength of the first network signal in each direction of the first signal receiving antenna 110 is different. In the network device 1 provided in this embodiment, the first signal receiving antenna 110 is rotatable, and when the first signal receiving antenna 110 is located in the direction in which the signal strength of the first network signal is strongest, the first signal receiving antenna 110 stays in the direction in which the signal strength of the first network signal is strongest. The signal conversion device 120 converts the first network signal with the strongest signal received by the first signal receiving antenna 110 into the second network signal. The signal conversion device 120 in the network device 1 in this embodiment converts the first network signal with the strongest signal into the second network signal, so as to ensure the signal strength of the second network signal, and further ensure the communication quality when communicating by using the second network signal.

In one embodiment, the first signal receiving antenna 110 can be rotated manually or automatically, as long as the first signal receiving antenna 110 can be rotated. In this application, a device for driving the first signal receiving antenna 110 to rotate automatically will be described later, taking as an example that the first signal receiving antenna 110 can be rotated automatically.

Optionally, in an embodiment, the network device 1 further includes a controller 130. The controller 130 is configured to determine a direction of the strongest signal strength according to the signal strength of the first network signal, and control the first signal receiving antenna 110 to rotate to the direction of the strongest first network signal.

Specifically, the controller 130 is electrically connected to the first signal receiving antenna 110, when the first signal receiving antenna 110 rotates, the first signal receiving antenna 110 can receive the first network signals in each direction, and the controller 130 compares the strength of the first network signals in each direction and determines the direction with the strongest signal strength. In this embodiment, the controller 130 controls the first signal receiving antenna 110 to rotate to the direction in which the first network signal is the strongest, so as to realize the automatic control of the rotation of the first signal receiving antenna 110.

Referring to fig. 5 and fig. 6 together, fig. 5 is a schematic structural diagram of a network device according to another embodiment of the present application; FIG. 6 is a schematic diagram of a driver according to an embodiment. Only the components of the network device 1 related to the first signal receiving antenna 110 and driving said first signal receiving antenna 110 are illustrated in fig. 5, while other components of said network device 1 are omitted. The network device 1 further comprises a base 140, a bracket 150, and a driver 160. The base 140 is rotatably connected to the bracket 150, the first signal receiving antenna 110 is disposed on the bracket 150, and the driver 160 is configured to receive a control signal from the controller 130 and drive the bracket 150 to rotate to a direction in which the first network signal is strongest relative to the base 140 under the control of the control signal.

The base 140 is stationary, for example, the base 140 may be directly or indirectly fixed to a housing 220 (see fig. 2) of the network device 1. The bracket 150 is rotatably connected to the base 140, and when the first signal receiving antenna 110 is disposed on the bracket 150, and the driver 160 drives the bracket 150 to rotate, the bracket 150 drives the first signal receiving antenna 110 to rotate. The driver 160 may include, but is not limited to including, a motor, etc. The base 140 forms an enclosure and the driver 160 is disposed within the enclosure formed by the base 140.

The first signal receiving antenna 110 includes a plurality of receiving units 112 to form an antenna array. In the present embodiment, the number of the receiving units 112 is 2 as an example. The receiving unit 112 is disposed on a substrate 113. The substrate 113 may be, but not limited to, a circuit board or the like.

In one embodiment, referring to fig. 6, the driver 160 includes a driving motor 161 and a reducer 162. The driving motor 161 is fixed on the base 140, the driving motor 161 is controlled by the control signal to rotate, the step angle of the driving motor 161 is a first angle, the speed reducer 162 is engaged with the output shaft of the driving motor 161 and the speed reducer 162 is rotationally connected to the support 150, and the speed reducer 162 is used for converting the first angle into a second angle, wherein the second angle is smaller than the first angle.

The driver 160 further includes a driving shaft 165, the driving shaft 165 is fixedly connected to the driving gear 164, and the driving shaft 165 is further fixedly connected to the bracket 150. When the driving gear 164 rotates, the driving shaft 165 rotates to drive the bracket 150 to rotate, and when the bracket 150 rotates, the first signal receiving antenna 110 disposed on the bracket 150 is driven to rotate.

Further, the driver 160 further includes a bearing 166, the bearing 166 is sleeved on the driving shaft 165, and the driving gear 164 is connected to the driving shaft 165 through the bearing 166.

The network device 1 further comprises a circuit board 180. The signal conversion device 120 and the controller 130 in the network device 1 are both disposed on the circuit board 180. The circuit board 180 is also referred to as a platelet. The components for driving the first signal receiving antenna 110 to operate are mainly disposed on the circuit board 180. For example, the circuit board 180 may further be provided with a power supply circuit, a protection circuit, and the like, so as to assist the signal conversion device 120 to convert the first network signal into the WiFi signal.

The step angle is a mechanical angle that the output shaft of the drive motor 161 rotates for one pulse of the control signal. The pitch angle of the drive motor 161 may be, but is not limited to, 3 °, 1.5 °, 0.75 °, 3.6 °, or 1.8 °. The larger the step angle is, the larger the angle of rotation of the output shaft of the driving motor 161 caused by one pulse of the control signal is, the larger the angle of rotation of the first signal receiving antenna 110 is driven to be; conversely, the smaller the step angle, the smaller the angle by which the output shaft of the driving motor 161 is rotated by one pulse of the control signal, and the smaller the angle by which the first signal receiving antenna 110 is rotated. When the step angle is larger, one pulse of the control signal causes the output shaft of the driving motor 161 to rotate by a larger angle, and the output shaft of the driving motor 161 needs to rotate by one circle with fewer pulses; conversely, when the step angle is smaller, one pulse of the control signal causes the output shaft of the drive motor 161 to rotate by a smaller angle, and the output shaft of the drive motor 161 needs to rotate by one turn more pulses. For example, for a drive motor 161 with a step angle of 1.8 °, the number of pulses required for one revolution is 360/1.8 — 200. Generally speaking, the step angle of the driving motor 161 is larger, if the reducer 162 is not used, and if the driving motor 161 is directly used to drive the bracket 150, the angle of each rotation of the bracket 150 is larger, then the angle of each rotation of the first signal receiving antenna 110 disposed on the bracket 150 is larger, which further results in that the number of the first network signals received by the first signal receiving antenna 110 during one rotation cycle is smaller, and further may cause inaccurate subsequent judgment of the first network signal with the strongest signal according to the signal strength of each acquired first network signal. For example, when the step angle of the rotation of the driving motor 161 is a first angle and the reducer 162 is not used, one pulse of the control signal causes the bracket 150 to rotate from the position a to the position B, and the direction of the first network signal with the strongest signal is located at the position C between the position a and the position B, so that the driving motor 161 cannot drive the first signal receiving antenna 110 to rotate to the point C because the step angle is too large, and the judgment of the first network signal with the strongest signal according to the signal strength of each acquired first network signal is inaccurate.

The speed reducer 162 is arranged in the network device 1, the first angle is converted into a smaller second angle, and when the driving motor 161 drives the support 150 through the speed reducer 162, the support 150 can rotate for a circle for a plurality of times. In other words, compared to the network device 1 without using the reducer 162, the reducer 162 in this embodiment may enable the first signal receiving antenna 110 to receive the first network signals in more directions, so as to improve the accuracy of determining the first network signal with the strongest signal according to the signal strength of each acquired first network signal.

In one embodiment, the reducer 162 includes a P-speed gear set 163 and a drive gear 164. Each stage of gear set 163 includes a first gear 1631 and a second gear 1632 that are coaxially and fixedly connected. The radius of the first gear 1631 in each stage of gear set 163 is greater than the radius of the second gear 1632 in the same stage of gear set 163. A first gear 1631 of the first gear set 163 of the P-gear set 163 engages the output shaft of the motor, and a second gear 1632 of the first gear set 163 engages the first gear 1631 of the second gear set 163. A first gear 1631 of the Q-th stage gear set 163 engages a second gear 1632 of the Q-1 th stage gear set 163, and a second gear 1632 of the Q-th stage gear set 163 engages a first gear 1631 of the Q +1 th stage gear set 163. The second gear 1632 of the P-th gear set 163 engages the driving gear 164, and the driving gear 164 is fixedly connected to the bracket 150. Q and P are positive integers, Q is greater than 1 and Q is less than P, the radius of the first gear 1631 in the Q-th gear set 163 is less than the radius of the first gear 1631 in the Q + 1-th gear set 163, and the radius of the first gear 1631 in the P-th gear set 163 is less than the radius of the driving gear 164.

In the present embodiment, the reduction gear 162 is illustrated as including a 2-stage gear set 163. It will be appreciated that reducer 162 may also include a stage 1 gear set 163, a stage 2 gear set 163, a stage 3 gear set 163, or even more stage gear sets 163.

In the present embodiment, the decelerator 162 includes a 2-stage gear set 163. Each stage of gear set 163 includes a first gear 1631 and a second gear 1632 that are coaxially and fixedly connected. The radius of the first gear 1631 in each stage of gear set 163 is greater than the radius of the second gear 1632 in the same stage of gear set 163. For purposes of this description, the 2-stage gear sets are designated as first stage gear set 163a and second stage gear set 163b, respectively. A first gear 1631 of the first stage gear set 163a engages the output shaft of the driving motor 161, and a second gear 1632 of the first stage gear set 163a engages the first gear 1631 of the second stage gear set 163 b. The second gear 1632 of the second stage gear set 163b engages the drive gear 164. The radius of the first gear 1631 in the first stage gear set 163a is smaller than the radius of the first gear 1631 in the second stage gear set 163, and the radius of the first gear 1631 in the second stage gear set 163b is smaller than the radius of the driving gear 164.

In this embodiment, when the speed reducer 162 includes the 1-stage gear set 163, the gear set 163 includes a first gear 1631 and a second gear 1632 which are coaxially and fixedly connected, and the radius of the first gear 1631 is larger than that of the second gear 1632; the first gear 1631 and an output shaft of the driving motor 161, and the second gear 1632 engages with the driving gear 164.

Referring to fig. 10, fig. 10 is a schematic structural diagram of a speed reducer according to another embodiment of the present application. In the present embodiment, when the speed reducer 162 includes the 3-stage gear set 163, each stage of the gear set 163 includes a first gear 1631 and a second gear 1632 which are coaxially and fixedly connected. The radius of the first gear 1631 in each stage of gear set 163 is greater than the radius of the second gear 1632 in the same stage of gear set 163. For purposes of the description, 3-stage gear set 163 is named first stage gear set 163a, second stage gear set 163b, and third stage gear set 163c, respectively. A first gear 1631 of the first stage gear set 163a engages the output shaft of the motor, and a second gear 1632 of the first stage gear set 163a engages the first gear 1631 of the second stage gear set 163 b. The second gear 1632 of the second stage gear set 163b engages the first gear 1631 of the third gear set 163, and the second gear 1632 of the third gear set 163 engages the drive gear 164. The driving gear 164 is fixedly connected to the bracket 150. The radius of first gear 1631 in first stage gear set 163a is smaller than the radius of first gear 1631 in second stage gear set 163b, the radius of first gear 1631 in second stage gear set 163b is smaller than the radius of first gear 1631 in third stage gear set 163c, and the radius of first gear 1631 in third stage gear set 163c is smaller than the radius of drive gear 164.

When the number of the gear sets 163 is larger, the smaller the second angle is, the more the accurate control of the rotation angle of the bracket 150 is facilitated, the more the first network signals in more directions are received, and the accuracy of judging the first network signal with the strongest signal according to the signal strength of each acquired first network signal is further facilitated. However, the more gear sets 163, the more time is required for installation of the gear sets 163, and the more space is occupied by the gear sets 163. Therefore, the number of the rotating gear sets 163 can be comprehensively considered in consideration of the accuracy of the rotational angle control of the carrier 150, the time taken to install the gear sets 163, and the space occupied by the gear sets 163.

In the present embodiment, the decelerator 162 includes 3 sets of gear sets 163. The driving motor 161 is fixed to the base 140, P is 3, and the first gear 1631 of the first-stage gear set 163 is disposed away from the base 140 compared with the second gear 1632 of the first-stage gear set 1631 and the gear set 163; a first gear 1631 of the second gear 1632 gear set 163 is disposed away from the base 140 as compared to a second gear 1632 of the second gear 1632 gear set 163; the first gear 1631 of the third gear set 163 is disposed adjacent to the base 140 compared to the second gear 1632 of the third gear set 163. In this embodiment, the gear set 163 is disposed in a manner such that the gear set 163 occupies a small volume, which is beneficial to improving the integration level of the speed reducer 162.

In this embodiment, the driver 160 drives the bracket 150 to rotate, so as to drive the first signal receiving antenna 110 to rotate in the first plane. In other embodiments, the driver 160 can further drive the bracket 150 to rotate to drive the first signal receiving antenna 110 to rotate in a first plane, and can further drive the bracket 150 to drive the first signal receiving antenna 110 to rotate in a second plane, where the first plane is different from the second plane. For example, the first plane may be an XY plane and the second plane may be a YZ plane.

When the driver 160 drives the bracket 150 to rotate to drive the first signal receiving antenna 110 to rotate in the first plane and the second plane, the first signal receiving antenna 110 can receive the first network signals in more directions. And the accuracy of judging the first network signal with the strongest signal according to the signal strength of the acquired first network signals is improved.

Referring to fig. 15 and 16 together, fig. 15 is a schematic structural diagram of a network device according to another embodiment of the present application; fig. 16 is a top view of fig. 15. The network device 1 of the present embodiment further includes a heat sink 190. The network device 1 comprising the heat sink 190 may be incorporated into the network device 1 provided in any of the previous embodiments. The first signal receiving antenna 110 comprises a receiving face 111 for receiving the first network signal. The network device 1 further comprises a heat dissipation element 190, wherein the heat dissipation element 190 is directly or indirectly disposed on a surface of the first signal receiving antenna 110 facing away from the receiving surface 111.

The heat sink 190 may be made of, but not limited to, metal with good thermal conductivity. The heat dissipation member 190 is used for dissipating heat when the first signal receiving antenna 110 operates, so as to prevent the first signal receiving antenna 110 from being unstable in performance due to overheating when the first signal receiving antenna 110 operates. In the present embodiment, the heat sink 190 further includes a plurality of heat dissipation fins 191, and the plurality of heat dissipation fins 191 are spaced apart from each other to improve a heat dissipation effect. Further, the size of the heat radiating fins 191 adjacent to the rotational axis of the first signal receiving antenna 110 is larger than the size of the heat radiating fins 191 away from the rotational axis.

Since there is a gap between the two ends of the first signal receiving antenna 110 and the housing 220 of the network device 1, the two ends of the first signal receiving antenna 110 are more easily heat-dissipated than the portion of the first signal receiving antenna 110 close to the rotation axis. In the network device 1 of the present application, the size of the heat radiation fins 191 adjacent to the rotation axis of the first signal receiving antenna 110 is set larger than the size of the heat radiation fins 191 distant from the rotation axis, and therefore, the uniformity of the heat radiation effect at each portion of the first signal receiving antenna 110 can be improved.

Further, in one embodiment, the length of the heat sink 191 is increased in the direction of the rotation axis from the end of the first signal receiving antenna 110. Such arrangement of the heat sink 191 can improve uniformity of heat dissipation effect at each portion of the first signal receiving antenna 110, and on the other hand, the heat sink does not easily touch other components in the network device 1 when the first signal receiving antenna 110 rotates.

Further, the heat sink 190 further includes a heat sink body 192, and the heat sink body 192 is attached to a surface of the first signal receiving antenna 110 away from the receiving surface 111. The plurality of fins 191 are provided on a surface of the heat dissipating body 192 facing away from the receiving surface 111. The heat dissipating body 192 may be, but is not limited to, rectangular in shape.

When the heat sink 190 further includes a heat sink body 192, the contact area between the heat sink body 192 and the first signal receiving antenna 110 is large, so that the heat of the first signal receiving antenna 110 can be rapidly dissipated.

The fan 240 is disposed corresponding to the first signal receiving antenna 110 for dissipating heat. The fan 240 is used to accelerate the air circulation near the first signal receiving antenna 110, so as to further improve the heat dissipation effect.

Further, a heat dissipation hole 221 is disposed on the housing 220 of the network device 1. The heat dissipation hole 221 communicates with a receiving space formed by the housing 220. When the fan 240 rotates, the air in the housing 220 is driven to interact with the air outside the housing 220 through the heat dissipation hole 221 to dissipate heat.

The network device 1 may include, but is not limited to, 8 second signal receiving antennas 210. Alternatively, two second signal receiving antennas 210 may constitute an antenna group 210a, which is disposed on the same substrate.

Due to the uncertainty of the position of the base station 3 transmitting the third network signal, there is also an uncertainty of the direction of transmission of the third network signal. The plurality of second signal receiving antennas 210 are fixed in position and are not rotatable. By distributing the second signal receiving antennas 210 along the circumference of the network device 1, a third network signal in multiple directions can be detected. And further, the accuracy of judging the third network signal with the strongest signal according to the signal strength of each acquired third network signal can be improved.

When the number of the selected second signal receiving antennas 210 is N, the sum of the signal strengths of the selected N second signal receiving antennas 210 is greater than the sum of the strengths of the third network signals received by any remaining N second signal receiving antennas 210 of the M second signal receiving antennas 210.

In an embodiment, the network device 1 further includes a driver 160 and a controller 130, when the first signal receiving antenna 110 receives a test command, the controller 130 controls the driver 160 to drive the bracket 150 to rotate at least one circle compared to the base 140 to obtain signal strengths of the first network signals in various directions, the controller 130 determines a direction with the strongest signal strength according to the signal strengths of the first network signals in various directions, and the controller 130 controls the driver 160 to drive the bracket 150 to rotate to a direction with the strongest signal strength.

The network device 1 has a test state and an operating state, the test state being located before the operating state. When the network device 1 is in the test state, the first signal receiving antenna 110 in the network device 1 receives the test signal and determines the direction in which the strength of the first network signal is strongest. And when the network device 1 determines the direction of the strongest first network signal in the test state, entering the working state. In other words, when the network device 1 is in an operating state, the first signal receiving antenna 110 is located at a predetermined position compared to the base 140, and at this time, the strength of the first network signal received by the first signal receiving antenna 110 is greater than the strength of the first network signal when the first signal receiving antenna 110 is located at other positions compared to the base 140.

Specifically, the network device 1 further includes a driver 160 and a controller 130. When the network device 1 is in a test state, the first signal receiving antenna 110 receives a test instruction, the controller 130 controls the driver 160 to drive the bracket 150 to rotate at least one circle compared with the base 140 to obtain the signal strength of the first network signal in each direction, the controller 130 determines the direction with the strongest signal strength according to the signal strength of the first network signal in each direction, and the controller 130 controls the driver 160 to drive the bracket 150 to rotate to the direction with the strongest signal strength.

In one embodiment, the network device 1 has a test state and an operating state, the test state preceding the operating state. The network device 1 further includes a memory 230, where the memory 230 stores a comparison table, where the comparison table includes a correspondence between the location of the network device 1 and a direction in which a first network signal strength corresponding to the location of the network device 1 is strongest, when the network device 1 is in a test state, the first signal receiving antenna 110 receives a test instruction, the controller 130 compares the current location of the network device 1 with the comparison table, and when the current location of the network device 1 matches the location of the network device 1 in the comparison table, the controller 130 controls the driver 160 to operate according to the comparison table, so that the first signal receiving antenna 110 is located in the direction in which the first network signal strength corresponding to the matched location is strongest.

Referring to fig. 26, 27 and 28 together, fig. 26 is a perspective view of a network device according to an embodiment of the present application; FIG. 27 is a cross-sectional perspective view of FIG. 26 taken along line A-A; FIG. 28 is a plan view of a section taken along line A-A of FIG. 26 in accordance with an embodiment; fig. 29 is an enlarged view of B in fig. 28. The network device 1 includes a key switch 310, a first circuit board 320, and a housing 220. The key switch 310 is disposed on the first circuit board 320. The housing 220 has a receiving space 300a, and the receiving space 300a is used for receiving the key switch 310 and the first circuit board 320. The housing 220 includes a sidewall 231, and the sidewall 231 includes a pressing portion 2311 and a sidewall body 2312 extending from the pressing portion 2311. The pressing portion 2311 is disposed corresponding to the key switch 310, and when the pressing portion 2311 is pressed and deformed, the key switch 310 is pressed.

The first circuit board 320 may be a small board or a large board, and in this embodiment, the first circuit board 320 is illustrated as a small board. The small board is a concept opposite to the large board, and both the small board and the large board are one of the circuit boards. From the appearance size, the small plate is close to a square, and the size of the small plate is generally 24.4cm x24.4 cm. The large panel is generally referred to as a standard ATX main panel, and is approximately rectangular in appearance size, and the size of the large panel is generally 30.5 cmx24.4cm. The small and large panels differ in that the large panel has greater dimensional and expansion properties than the small panel. For example, a large board usually has 4 memory slots, and a small board usually has only 2 memory slots, so the small board has less memory capacity than the large board. The number of interfaces of the large board is also larger than the number of interfaces of the small board. Generally speaking, the larger the number of interfaces, the more hard disks, optical drives, etc. can be accessed. The interface may be, but is not limited to, a Universal Serial Bus (USB) interface, etc. Generally, the number of USB interfaces on a small board is 4, and the number of USB interfaces on a large board is 8.

The key switch 310 is disposed on the first circuit board 320 by soldering, but not limited to soldering on the first circuit board 320. When the key switch 310 is pressed, the network device 1 may be triggered to turn on or off, or the network device 1 may be automatically connected to the end point device 5. The function performed when the key switch 310 is pressed is not limited in the present application.

In this embodiment, the side wall 231 is an integral structure, and there is no gap or opening at the position of the side wall 231 corresponding to the key switch 310, so that the structural design of the network device 1 can prevent moisture outside the network device 1 from entering the key switch 310 and the small plate through the gap or opening corresponding to the key switch 310.

The housing 220 of the network device 1 may be in the shape of a multi-sided cylindrical barrel, or a cylindrical barrel. The network device 1 includes a top wall 220a, a bottom wall 220b, and a peripheral side wall 220 c. The top wall 220a is disposed opposite to the bottom wall 220b, and the peripheral side wall 220c is connected between the top wall 220a and the bottom wall 220b and connected to the peripheral edges of the top wall 220a and the bottom wall 220 b. The side wall 231 is a peripheral side wall 220c of the network device 1 or a top wall 220a of the network device 1 or a bottom wall 220b of the network device 1. In view of the convenience of the pressing portion 2311 when a user presses and presses, the side wall 231 is the peripheral side wall 220c or the top wall 220a of the network device 1, and in the present embodiment, the side wall 231 is the top wall 220a of the network device 1 as an example.

In order to facilitate the pressing of the user, an indication pattern is generally disposed on the pressing portion 2311 to guide the user to press the key switch 310.

Further, the side wall 231 includes an inner wall 2314 and an outer wall 2316. The inner wall 2314 has a through hole 2315. The elasticity of the outer wall 2316 is greater than that of the inner wall 2314, the outer wall 2316 is connected with the inner wall 2314, the outer wall 2316 is arranged on the outer side of the inner wall 2314, the outer wall 2316 is provided with an outer wall body 2317 and an extension 2318, the extension 2318 extends from the inner side of the outer wall body 2317 to the inner wall 2314 and penetrates through the through hole 2315, and the extension 2318 is at least partially opposite to the key switch 310.

The portion of the outer wall body 2317 of the outer wall 2316 corresponding to the through hole 2315 and the extension 2318 form the pressing portion 2311. The material of the outer wall 2316 may be, but is not limited to, soft rubber such as Thermoplastic Polyurethane (TPU), Thermoplastic Elastomer (TPE), Thermoplastic polyester Elastomer (TPEE), and the like. The inner wall 2314 may be made of, but not limited to, plastic. The inner wall 2314 is harder than the outer wall 2316, such that the inner wall 2314 supports the outer wall 2316, and the side wall 231 has greater strength and rigidity. The inner wall 2314 has a smaller elasticity than the outer wall 2316, so that the key portion is easily deformed and pressed to the key switch 310. The outer wall 2316 may be combined with the inner wall 2314 by, but not limited to, forming an integral structure with the inner wall 2314 by two-shot molding or oil pressure molding. Since the material of the outer wall 2316 is different from that of the inner wall 2314, the outer wall 2316 has a good texture when used as an appearance surface.

Referring to fig. 29, the extension 2318 and the key switch 310 being at least partially opposite to each other includes the extension 2318 and the key switch 310 being completely opposite to each other and the extension 2318 and the key switch 310 being partially opposite to each other. When the extension 2318 and the key switch 310 are completely aligned, the center of the orthographic projection of the key switch 310 on the plane where the extension 2318 is located coincides with the center of the area where the extension 2318 is located. At this time, when the extension portion 2318 is completely aligned with the key switch 310, when the pressing portion 2311 is pressed, each portion of the extension portion 2318 contacts the key switch 310 more uniformly, so that the key switch 310 can be effectively pressed to a certain extent.

Referring to fig. 30 and 31, fig. 30 is a plan view of fig. 26 taken along line a-a in another embodiment; fig. 31 is an enlarged schematic view at C in fig. 30. In this embodiment, the extension 2318 is partially opposite to the key switch 310. In other words, the orthographic projection of the key switch 310 on the plane where the extension 2318 is located partially coincides with the area where the extension 2318 is located, and the center of the key switch 310 on the plane where the extension 2318 is located does not coincide with the center of the area where the extension 2318 is located. Whether the extension portion 2318 is completely opposite to the key switch 310 or not, it is only required to ensure that at least part of the extension portion 2318 contacts the key switch 310 when the pressing portion 2311 is pressed, and the key switch 310 is effectively pressed.

The effective pressing means that when the key switch 310 is pressed, the key switch 310 can trigger the first circuit board 320 to perform corresponding actions. The valid pressing is a concept opposite to the invalid pressing, and when the key switch 310 is pressed, but the key switch 310 is not pressed to a position, so that the key switch 310 does not trigger the first circuit board 320 to perform a corresponding action, the key switch 310 is pressed but is an invalid pressing.

In one embodiment, the extension 2318 and the inner wall 2314 form a gap between the walls of the through hole 2315 (see fig. 29, 31). The gap is an escape space of the extension portion 2318, so that a large enough deformation space is provided when the pressing portion 2311 is pressed, and further, when the pressing portion 2311 is pressed, the extension portion 2318 can touch the key switch 310, so that the key switch 310 is effectively pressed. Further, when there is a gap between the extension 2318 and the wall of the inner wall 2314 forming the through hole 2315, the pressing portion 2311 has a better pressing touch when pressed.

Referring to fig. 32 and 33, fig. 32 is a plan view of fig. 26 taken along line a-a in another embodiment; fig. 33 is an enlarged view of D in fig. 32. In the present embodiment, the extension portion 2318 and the hole wall of the inner wall 2314 forming the through hole 2315 do not have a gap therebetween, in other words, the extension portion 2318 and the hole wall of the inner wall 2314 forming the through hole 2315 abut against each other. In this embodiment, there is no gap between the extension 2318 and the wall of the inner wall 2314 forming the through hole 2315, and compared with the gap between the extension 2318 and the wall of the inner wall 2314 forming the through hole 2315, the deformation space of the extension 2318 is smaller, but the key switch 310 can be effectively pressed, and meanwhile, the wall of the inner wall 2314 forming the through hole 2315 positions the extension 2318, so that the extension 2318 is prevented from shaking and being unable to press the key switch 310.

In some embodiments (see fig. 29, 31, 33), the extension 2318 abuts the key switch 310. The extension portion 2318 abuts against the key switch 310, so that when the pressing portion 2311 is pressed to drive the extension portion 2318 to press the key switch 310, the key switch 310 can be effectively pressed by small deformation of the extension portion 2318.

Referring to fig. 34 and 35, fig. 34 is a plan view of fig. 26 taken along line a-a in another embodiment; fig. 35 is an enlarged view at E in fig. 34. In one embodiment, the extension 2318 has a gap with the key switch 310. When a gap exists between the extension portion 2318 and the key switch 310, the size of the gap between the extension portion 2318 and the key switch 310 may be, but is not limited to, 0.1mm, and although the gap exists between the extension portion 2318 and the key switch 310, since the housing may deform, when the pressing portion 2311 is pressed to drive the extension portion 2318 to press the key switch 310, the key switch 310 may still be effectively pressed.

In an embodiment, an orthographic projection of the key switch 310 in a plane of the outer wall 2316 falls within a region of the extension 2318, and an area of the orthographic projection of the key switch 310 in the plane of the outer wall 2316 is smaller than an area of the region of the extension 2318.

In other words, the lateral dimension of the key switch 310 is smaller than the lateral dimension of the extension 2318, and the extension 2318 protrudes laterally beyond the key switch 310. The structure of the key switch 310 and the extension 2318 according to this embodiment can enable the extension 2318 to be pressed onto the key switch 310 even if the extension 2318 is partially offset from the key switch 310 when the pressing portion 2311 is pressed.
