Description

Technical Field

[0001] The utility model relates to the technical field of communications, and in particular to a CPE device and a communication system. Background Art

[0002] Customer Premises Equipment (CPE) is a wireless broadband access device that converts analog signals received from base stations or other network devices into Wi-Fi signals. Due to limitations in space and hardware, existing CPE antennas operate in less-than-ideal signal environments. This can lead to poor antenna signal quality in scenarios with weak wireless signals, impacting the normal operation of the CPE. Utility Model Content

[0003] The present invention aims to solve at least one of the problems existing in the prior art. To this end, the present invention provides a CPE device and a communication system. The CPE device can improve the antenna environment when the wireless signal in the scene is weak, thereby improving the quality of the antenna signal and ensuring the normal use of the CPE device.

[0004] In order to achieve the above objectives, the present invention provides a CPE device, including:

[0005] The shell is provided with at least two windows spaced apart along the circumference, each of the windows being connected to the accommodating cavity of the shell;

[0006] At least two cover plates, each of which is disposed correspondingly at one of the window openings, and each of which has a mounting portion on a side facing the accommodating cavity;

[0007] A CPE mainboard is installed in the accommodating cavity;

[0008] At least two antenna units, each of the antenna units is mounted on a corresponding mounting portion of the cover plate, and each of the antenna units is connected to the CPE mainboard; and

[0009] a driving mechanism mounted on the housing and connected to each of the cover plates;

[0010] In which, the driving mechanism is used to drive each of the cover plates to extend outward relative to the shell to open the window corresponding to the cover plate and move each of the antenna units away from the CPE mainboard, or to drive each of the cover plates to retract inward relative to the shell to close the window corresponding to the cover plate and move each of the antenna units close to the CPE mainboard.

[0011] In one embodiment, when the driving mechanism drives each of the cover plates to extend outward relative to the shell until the corresponding window of the cover plate is opened, each of the antenna units is away from the CPE mainboard and at least partially exposed to the shell through the window.

[0012] In one embodiment, the entirety of each antenna unit is exposed outside the housing through the corresponding window.

[0013] In one embodiment, the at least two windows are symmetrically distributed about the axis of the shell.

[0014] In one embodiment, each of the windows extends along the axial direction of the housing.

[0015] In one embodiment, the window has a first end and a second end opposite to each other in the axial direction of the housing, and the first end of each window extends to the same end that passes through the housing in the axial direction.

[0016] In one embodiment, the driving mechanism is used to drive each of the cover plates to extend outward relative to the housing along a first motion trajectory, or to drive each of the cover plates to retract inward relative to the housing along a second motion trajectory;

[0017] The first motion trajectory is a motion trajectory away from the shell along the radial direction of the shell, and the second motion trajectory is a motion trajectory approaching the shell along the radial direction of the shell.

[0018] In one embodiment, the driving mechanism is used to drive each of the cover plates to extend outward relative to the housing along a first motion trajectory, or to drive each of the cover plates to retract inward relative to the housing along a second motion trajectory;

[0019] Among them, the first motion trajectory is a trajectory that moves away from the shell along the radial direction of the shell and moves toward the first end of the shell along the axial direction of the shell, and the second motion trajectory is a trajectory that approaches the shell along the radial direction of the shell and moves toward the second end of the shell along the axial direction of the shell.

[0020] In one embodiment, the driving mechanism includes a driving motor and at least two groups of connecting components, each group of the connecting components is connected between the driving motor and a corresponding cover plate, and the rotation of the driving motor drives the connecting components to move, thereby driving the corresponding cover plate to move along the first motion trajectory or the second motion trajectory.

[0021] On the other hand, the present invention further provides a communication system, comprising the CPE device as described in any of the above embodiments.

[0022] In the CPE device and communication system provided by the present invention, the driving mechanism drives each of the cover plates to extend or retract relative to the shell, so that the CPE device can switch between different working states, so that it can be applied in different scenarios. When the wireless signal (such as 5G signal) in the scene where the CPE device is located is weak, the driving mechanism drives each of the cover plates to extend relative to the shell to make the CPE device work in the first working state, so that each of the antenna units is away from the CPE mainboard, which can increase the clearance area of the antenna unit, thereby reducing the electromagnetic influence of the electrical components on the CPE mainboard on the antenna signal, improving the environment of the antenna unit, and improving the quality of the antenna signal, thereby ensuring the normal use of the CPE device. Furthermore, each of the antenna units is away from the CPE mainboard, that is, all of the antenna units are away from the CPE mainboard. The units are far away from each other, which can also improve the isolation between the antenna units of the same frequency, which is beneficial to compensate for the polarization mismatch loss; on the contrary, when the wireless signal coverage of the scene where the CPE device is located is perfect, the driving mechanism drives each of the cover plates to retract relative to the shell to make the CPE device work in the second working state, so that the cover plate closes the corresponding window, and each of the antenna units is close to the CPE mainboard and accommodated in the accommodating cavity of the shell, which not only ensures that the CPE device can be used normally, but also reduces the volume of the CPE device and reduces the space occupancy of the CPE device.

[0023] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0035] Please also refer to Figures 1 to 5 The embodiment of the present invention provides a CPE device 100, including a housing 10, at least two cover plates 20, a CPE mainboard 30, at least two antenna units 40, and a driving mechanism 50. Specifically, as Figure 2 and Figure 4As shown, the housing 10 has a receiving cavity 11 and at least two windows 12 spaced apart along the circumference, each of the windows 12 being connected to the receiving cavity 11; Figures 2 to 5 As shown, each of the cover plates 20 is correspondingly arranged at one of the windows 12, and a mounting portion 21 is provided on a side of each of the cover plates 20 facing the accommodating cavity 11 (see FIG. Figure 4 and Figure 5 );like Figure 2 and Figure 4 As shown, the CPE mainboard 30 is installed in the accommodating cavity 11; Figure 5 As shown, each of the antenna units 40 is mounted on a mounting portion 21 of the cover plate 20, and each of the antenna units 40 is connected to the CPE mainboard 30 (see Figure 4 The driving mechanism 50 is mounted on the housing 10 and connected to each of the cover plates 20, so that each of the cover plates 20 is connected to the housing 10 via the driving mechanism 50. The specific structure of the driving mechanism 50 will be described below with examples.

[0036] It is important to note that, in the embodiment of the present invention, the driving mechanism 50 is used to drive each of the cover plates 20 to extend relative to the housing 10 (i.e., move in a direction away from the housing 10) to open the window 12 corresponding to the cover plate 20 and move each of the antenna units 40 away from the CPE mainboard 30 (see FIG. Figure 4 ), at which point the CPE device 100 operates in the first operating state; alternatively, the driving mechanism 50 is used to drive each cover plate 20 to retract relative to the housing 10 (i.e., move toward the housing 10), thereby closing the corresponding window 12 of the cover plate 20 and bringing each antenna unit 40 closer to the CPE mainboard 30. In other words, by driving each cover plate 20 to extend or retract relative to the housing 10 by the driving mechanism 50, the CPE device 100 can be switched between the first and second operating states, thereby enabling application in different scenarios.

[0037] It is not difficult to understand that in the embodiment of the present invention, when the wireless signal (not limited to 5G signal) in the scene where the CPE device 100 is located is weak, the driving mechanism 50 drives each of the cover plates 20 to extend relative to the shell 10 so that the CPE device 100 operates in the first working state, so that each of the antenna units 40 is away from the CPE mainboard 30, which can increase the clearance area of the antenna unit 40, thereby reducing the electromagnetic influence of the electrical components on the CPE mainboard 30 on the antenna signal, improving the environment of the antenna unit 40, and improving the quality of the antenna signal, thereby ensuring the normal use of the CPE device 100. Furthermore, each of the antenna units 40 is away from the CPE mainboard 30, that is, the entire antenna unit 40 is away from the CPE mainboard 30. The antenna units 40 are kept away from each other, and the isolation between the antenna units 40 of the same frequency can be improved, which is beneficial to compensating for the polarization mismatch loss; on the contrary, when the wireless signal coverage of the scene in which the CPE device 100 is located is perfect, the driving mechanism 50 drives each of the cover plates 20 to retract relative to the shell 10 so that the CPE device 100 works in the second working state, so that the cover plate 20 closes the corresponding window 12, and each of the antenna units 40 is close to the CPE mainboard 30 and accommodated in the accommodating cavity 11 of the shell 10, which not only ensures that the CPE device 100 can be used normally, but also reduces the volume of the CPE device 100 and reduces the space occupancy rate of the CPE device 100.

[0038] Preferably, see Figure 5 In an embodiment of the present invention, when the driving mechanism 50 drives each of the cover plates 20 to extend relative to the housing 10 until the corresponding window 12 of the cover plate 20 is opened, each of the antenna units 40 is away from the CPE mainboard 30 and at least partially exposed to the housing 10 through the window 12. At least a portion of the antenna unit 40 can be exposed outside the housing 10 without being restricted by the housing 10, which can further increase the clearance area of the antenna unit 40, thereby further improving the quality of the antenna signal. More preferably, in Figure 5 In the example, each antenna unit 40 is exposed to the shell 10 through the corresponding window 12. In this way, not only can the clearance area of the antenna unit 40 be maximized to improve the quality of the antenna signal as much as possible, but the accommodating cavity 11 of the shell 10 can also be connected with the external space, which is beneficial to improving the heat dissipation efficiency of the CPE device 100.

[0039] Please refer again Figures 2 to 5 In one embodiment of the present invention, the shell 10 is a cylindrical shell with a hexagonal axial cross-section. The shell 10 has six side planes in the circumference, and a window 12 is provided in the connecting area between each two adjacent side planes.

[0040] In other embodiments, the shell 10 may also directly open the window 12 on the side plane, and one window 12 may be opened between every two side planes, or one window 12 may be opened between every three side planes, as long as the shell 10 has at least two windows 12 spaced circumferentially.

[0041] In other embodiments, the housing 10 may be a cylindrical housing with an axial cross-section having a circular or elliptical shape, or other shapes, without limitation. Of course, the housing 10 may also be other shapes besides a cylindrical shape, such as, but not limited to, a block-shaped housing, as long as at least two windows 12 are provided spaced apart in the circumferential direction. This is also not a limitation.

[0042] Preferably, Figures 2 to 5 In the example, each of the windows 12 extends along the axial direction of the housing 10. It is understood that when the housing 10 needs to have a certain number of windows 12, compared to extending the windows 12 along the circumferential direction or other non-axial directions of the housing 10, setting the windows 12 to extend along the axial direction of the housing 10 can reduce the radial dimension of the housing 10, thereby facilitating a lightweight design of the CPE device 100.

[0043] wherein, optionally, Figures 2 to 5 In the example, the window 12 has a first end and a second end opposite to each other in the axial direction of the housing 10, and the first end of each window 12 extends to the same end (for example, Figure 4 The upper end shown in FIG. In other words, in this embodiment, the window 12 is a window with one end open and the other closed. By setting the first end of the window 12 to extend through the same axial end of the housing 10, the difficulty of manufacturing the window 12 can be reduced, while also reducing the weight of the housing 10. Of course, in other embodiments, the window 12 may not extend through the same axial end of the housing 10; that is, the window 12 may be a window with both ends closed.

[0044] like Figures 2 to 5 As shown, in one embodiment of the present invention, the cover plate 20 is a substantially rectangular plate, and the shape of the cover plate 20 is adapted to the shape of the window 12 to ensure that the cover plate 20 can be moved from the outside of the housing 10 toward the housing 10 to cover the window 12 under the drive of the driving mechanism 50. Figures 2 to 5In the example, the mounting portion 21 on the cover plate 20 is a pair of mounting posts extending toward the accommodating cavity 11 of the housing 10. The antenna unit 40 can be mounted on the corresponding mounting portion 21 of the cover plate 20 by, but is not limited to, winding. Of course, in other embodiments, the mounting portion 21 can also be other structures, such as, but not limited to, a mounting frame provided on the side of the cover plate 20 facing the accommodating cavity 11. The antenna unit 40 is embedded in the mounting frame and can also be mounted on the corresponding mounting portion 21 of the cover plate 20.

[0045] Preferably, Figure 5 As shown, in one embodiment of the present invention, the at least two windows 12 on the shell 10 are symmetrically distributed about the axis of the shell 10. In this way, the at least two cover plates 20 corresponding to the at least two windows 12 are also symmetrically distributed about the axis of the shell 10, so that the at least two antenna units 40 installed on the mounting portions 21 of the at least two cover plates 20 are symmetrically distributed, which is beneficial to improving the uniformity of the at least two antenna units 40 when receiving or sending signals, thereby improving the performance of the CPE device 100.

[0046] Please also refer to Figure 4 and Figure 6 In one embodiment of the present invention, the drive mechanism 50 includes a drive motor (not shown) and at least two sets of connecting assemblies. Each set of connecting assemblies is connected between the drive motor and a corresponding cover plate 20. The rotation of the drive motor drives the connecting assemblies to move the corresponding cover plate 20 along a first motion trajectory to extend relative to the housing 10, or to move the corresponding cover plate 20 along a second motion trajectory to retract relative to the housing 10. The first motion trajectory and the second motion trajectory are opposite motion trajectories.

[0047] It is understandable that when the connecting assembly adopts different combinations of existing components such as push rods, swing rods, cams, etc., the first motion trajectory and the second motion trajectory of the cover plate 20 will also be different.

[0048] Specifically, in Figure 4 and Figure 6In the example, the driving mechanism 50 may include a plurality of driving motors and a plurality of connecting components that are the same in number as the windows 12, each of the connecting components including two pairs of swinging rods 51, wherein the two pairs of swinging rods 51 are spaced apart along the axial direction of the shell 10, and each pair of the swinging rods 51 are respectively arranged on opposite sides of the cover plate 20 along the circumference of the shell 10, one end of each swinging rod 51 is rotationally connected to the side wall of the corresponding side of the cover plate 20, and the other end of each swinging rod 51 is rotationally connected to the portion of the shell 10 adjacent to the window 12, and the other end of one of the swinging rods 51 connected to the cover plate 20 is connected to the output shaft of the corresponding driving motor, so that the cover plate 20 is connected to the shell 10 through the two pairs of swinging rods 51, and the rotation of the driving motor can drive the connected swinging rod 51 to swing, thereby realizing the extension or retraction of the cover plate 20 relative to the shell 10. More specifically, in Figure 4 and Figure 6 In the example, when the driving mechanism 50 drives each of the cover plates 20 to extend relative to the shell 10 along the first motion trajectory, the first motion trajectory is a trajectory that moves away from the shell 10 in the radial direction of the shell 10 and moves toward the first end of the shell 10 (for example, the upper end shown in the figure) along the axial direction of the shell 10; when the driving mechanism 50 drives each of the cover plates 20 to retract relative to the shell 10 along the second motion trajectory, the second motion trajectory is a trajectory that moves closer to the shell 10 in the radial direction of the shell 10 and moves toward the second end of the shell 10 (for example, the lower end shown in the figure) along the axial direction of the shell 10. That is, in Figure 4 and Figure 6 In the example, when the driving mechanism 50 adopts a driving motor and a connecting assembly composed of multiple pairs of swing rods 51, the driving mechanism 50 can drive each of the cover plates 20 to extend or retract relative to the shell 10 in an oblique swinging motion.

[0049] In other embodiments, each of the connecting components may also include three or more pairs of swing rods 51, which is not limited to this.

[0050] Of course, in other embodiments, the driving mechanism 50 may include a driving motor and a plurality of connecting assemblies having the same number as the windows 12, the output shaft sleeve of the driving motor is provided with a cam in the form of a plum blossom pile, the cam having flanges corresponding to the at least two windows 12 one by one, the connecting assembly includes a push rod, a spring and a plurality of telescopic rods, each of the cover plates 20 is connected to the housing 10 through a plurality of telescopic rods of the corresponding connecting assembly, and each of the cover plates 20 is connected to one end of the push rod of the corresponding connecting assembly, and the other end of the push rod is connected to a corresponding one on the cam. The flanges are in sliding contact, and the extension and retraction direction of each telescopic rod and the movement direction of the push rod under the limitation of the limiting structure are both radially of the housing 10. The spring is connected between the cover plate 20 and the housing 10 to provide a pulling force to pull the cover plate 20 toward the housing 10. In this way, under the action of the spring, the drive motor is controlled to rotate forward or reverse as needed to drive the cam to rotate, and the flange of the cam can drive the corresponding push rod to retract and retract along the radial direction of the housing 10, thereby achieving the extension or retraction of the cover plate 20 relative to the housing 10. More specifically, in this embodiment, when the drive mechanism 50 drives each cover plate 20 to extend relative to the housing 10 along a first motion trajectory, the first motion trajectory is a motion trajectory away from the housing 10 along the radial direction of the housing 10; when the drive mechanism 50 drives each cover plate 20 to retract relative to the housing 10 along a second motion trajectory, the second motion trajectory is a motion trajectory approaching the housing 10 along the radial direction of the housing 10. In other words, when the driving mechanism 50 adopts a driving motor with a cam and a connecting assembly composed of a push rod, a spring and multiple telescopic rods, the driving mechanism 50 can drive each of the cover plates 20 to extend or retract relative to the shell 10 in a linear reciprocating motion.

[0051] It can also be understood that in other embodiments, the driving mechanism 50 can also adopt other component combinations, such as but not limited to a combination of a cylinder and multiple connecting rods. The telescopic movement of the telescopic rod of the cylinder can also achieve the purpose of extending or retracting the cover plate 20 relative to the shell 10, which will not be elaborated.

[0052] It should be noted that, similar to existing CPE devices, in the CPE device 100 provided by the present invention, the antenna unit 40 may include one or more combinations of existing antennas such as a WiFi antenna, an LTE antenna, and a 5G antenna, which will not be described in detail. The driving mechanism 50 can receive a control signal sent by the CPE mainboard 30, or receive a control signal sent by a controller independent of the CPE mainboard 30, and then drive each of the cover plates 20 to extend or retract relative to the housing 10 according to different control signals. The CPE mainboard 30 or the controller can send different control signals based on the strength of the wireless signal in the scene where the CPE device 100 is located. The specific working principle can adopt existing technology and will not be described in detail. In addition, in the embodiment of the present invention, the CPE mainboard 30 can adopt an existing CPE circuit mainboard, and the specific structure and electrical component composition are not limited.

[0053] It should also be noted that in the embodiment of the present invention, similar to the existing CPE device, the CPE device 100 also includes components such as an indicator light 13, a functional interface 14 and a switch 15, which are arranged in the shell 10 and connected to the CPE mainboard 30. Other structures are also provided in the shell 10, such as but not limited to an installation structure for installing the CPE mainboard 30, which will not be elaborated on.

[0054] Furthermore, an embodiment of the present invention provides a communication system including a CPE device. The CPE device may be the CPE device 100 described in any of the aforementioned embodiments, and thus has at least all the beneficial effects of the technical solutions of the aforementioned embodiments.

[0055] It is understandable that, similar to the existing communication system, the communication system may further include other components such as a network device connected to the CPE device 100, which will not be described in detail.
