Description

Wireless communication device

Technical Field

The present invention relates to a communication device, and more particularly, to a wireless communication device.

Background

A Wireless Local Area Network (WLAN) is a Local Area Network that uses radio waves to transmit data without using a cable connection. Electronic devices such as computers and mobile phones used by wlan users need to connect to the wlan through radio waves transmitted by one or more Wireless Access points (Wireless APs). Currently, wireless local area networks are widely used in work, teaching, and various public and traffic areas.

However, in the space used by the user, there is a blind spot (blind spot) where the radio wave transmitted by the wireless receiver is difficult to reach, so that the transmission efficiency of the electronic device at this position is low, or even the electronic device cannot be connected to the wireless local area network. In order to improve the wireless local area network signal in the blind spot region, the conventional wireless receiver adds extra antennas, uses a Multi-input Multi-output (MIMO) technique, or enhances radiation. However, the above solution increases the overall power consumption and cannot further adjust the signal distribution. On the other hand, the high-power antenna is also easy to cause damage to the adjacent human body and organism.

It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, the "first element," "first part," "first region," "first layer," or "first portion" discussed below can be referred to as a "second element," "second part," "second region," "second layer," or "second portion" without departing from the teachings herein.

Referring to fig. 1, in the first embodiment of the present invention, the wireless communication device 100 includes a host module 110, a sub-module 120A, a sub-module 120B, a sub-module 120C, and a sub-module 120D. The host module 110 includes a first housing 112, and the first housing 112 has a carrying surface 111. The handset module 120A includes a second housing 122A; the handset module 120B includes a second housing 122B; the sub-machine module 120C includes a second housing 122C; the sub-module 120D includes a second housing 122D. The four sub-modules 120A-120D are taken as an example in the embodiment, but the invention is not limited thereto. In other embodiments of the present invention, the number of the sub-modules in the wireless communication device can be adjusted according to the requirement and the energy consumption.

In the first embodiment of the invention, when the sub-machine module 120A, the sub-machine module 120B, the sub-machine module 120C and the sub-machine module 120D are disposed on the host machine module 110, the carrying surface 111 of the first housing 112 can carry the second housing 122A, the second housing 122B, the second housing 122C and the second housing 122D. In other words, the first housing 112 of the host module 110 provides a carrying surface 111 for the sub-modules 120A, 120B, 120C, and 120D to be placed on the host module 110.

In the wireless communication device 100 of the present embodiment, the host module 110 sends a host signal 113; the handset module 120A sends out a handset signal 121A; the handset module 120B sends out a handset signal 121B; the sub-machine module 120C sends out a sub-machine signal 121C; the handset module 120D sends a handset signal 121D.

Specifically, the host signal 113 sent by the host module 110 of the present embodiment is, for example, the host signal 113 sent towards the periphery. When the

sub-machine modules

120A, 120B, 120C, 120D are placed in the master machine module, the sub-machine module 120A is fixed to transmit the sub-machine signal 121A along the first direction D1; the handset module 120B is fixed to transmit the handset signal 121B along the first direction d 2; the handset module 120C is fixed to transmit the handset signal 121C along the first direction d 3; the handset module 120D is fixed to transmit the handset signal 121D along the first direction D4. Therefore, the sub-modules 120A, 120B, 120C, and 120D can further enhance the signal strength around the host module 110, so as to provide better signal quality in the wireless communication range (not shown), i.e. around the wireless communication device 100 of the embodiment.

When the

sub-machine modules

120A, 120B, 120C, and 120D of the present embodiment are far away from the carrying surface 111, by selectively adjusting the distances between the

sub-machine modules

120A, 120B, 120C, and 120D and the host machine module 110, and the respective first directions D1, D2, D3, and D4 of the sub-machine signals 120A, 120B, 120C, and 120D, the wireless communication range of the wireless communication device 100 can change the distribution area according to the environment, thereby providing good signal quality.

Fig. 2 is a schematic diagram of a host module and a sub-module according to a first embodiment of the invention. Referring to fig. 2, in the wireless communication device 100 of the present embodiment, the host module 110 includes a host communication unit 114, and the host communication unit 114 is disposed in the first housing 112; the handset module 120A includes a handset communication unit 124A, and the handset communication unit 124A is disposed in the second housing 122A. It should be noted that, the sub-machine module 120A is taken as an example and is not intended to limit the present invention; those skilled in the art can apply to other sub-modules. On the other hand, for the sake of clarity of the embodiment of the present invention, fig. 2 is only schematically illustrated in the drawings, and the size of the elements is not intended to limit the present invention.

Referring to fig. 2, in the first embodiment of the present invention, since the host communication unit 114 is disposed on the first housing 112 and the sub-machine communication unit 124A is disposed on the second housing 122A, the sub-machine module 120A can be disposed on the host module 110 or can be removed from the host module 110. Therefore, the wireless communication device 100 can further adjust the wireless network range by the host signal 113 and the slave signal 121A.

On the other hand, the handset signal 121A of the present embodiment can be converted from the host signal 113, for example. Further, the data transmission between the host communication unit 114 and the sub-unit communication unit 124A can be achieved by, for example, the host signal 113 sent by the host communication unit 114, and the sub-unit communication unit 124A converts the host signal 113 into the sub-unit signal 121A and sends the sub-unit signal, but the invention is not limited thereto. In other embodiments, other wireless transmission methods can be used to achieve the data transmission between the host module 110 and the sub-module 120A.

Referring to fig. 1, the

sub-machine modules

120A, 120B, 120C, and 120D according to the first embodiment of the invention further include

indication units

123A, 123B, 123C, and 123D, respectively. In detail, referring to fig. 1, in the first embodiment of the present invention, the indication unit 123A of the sub-machine module 120A indicates the first direction d 1; the indicating unit 123B of the child module 120B indicates the first direction d 2; the indicating unit 123C of the child module 120C indicates the first direction d 3; the instruction unit 123D of the child module 120D indicates the first direction D4. Since the sub-device signals 121A, 121B, 121C, 121D of the

sub-device modules

120A, 120B, 120C, 120D are substantially respectively sent along the first directions D1, D2, D3, D4 in the first embodiment of the present invention, the

indication units

123A, 123B, 123C, 123D can clearly indicate the first directions D1, D2, D3, D4, so that the user can clearly adjust the transmission directions of the sub-device signals 121A, 121B, 121C, 121D. Here, the

indication units

123A, 123B, 123C and 123D are exemplarily illustrated according to the embodiment, which is not intended to limit the present invention, and a person skilled in the art can also use, for example, an arrow or a character to indicate the direction of the first direction as required.

Further, when the wireless communication device 100 of the embodiment includes the plurality of

sub-machine modules

120A, 120B, 120C, 120D and a plurality of receiving slots, and the

sub-machine modules

120A, 120B, 120C, 120D are disposed in the receiving slots, the

sub-machine modules

120A, 120B, 120C, 120D transmit the sub-machine signals 121A, 121B, 121C, 121D in a 360 degree direction with respect to the host machine module 110, that is, the

sub-machine modules

120A, 120B, 120C, 120D transmit the sub-machine signals 121A, 121B, 121C, 121D to the outside with respect to the host machine module 110, so as to substantially form an omni-directional communication range coverage. However, the invention is not limited thereto, and in other embodiments of the invention, the handset signals 121A, 121B, 121C, 121D can also be transmitted along a specific direction on the host module 110, so as to achieve a specific requirement or cover a specific range.

Fig. 3A and fig. 3B are schematic diagrams of a wireless communication device according to a second embodiment of the invention. Referring to fig. 3A, the wireless communication device 200 according to the embodiment of the invention includes a host module 210 and at least one sub-module (here, the sub-module 220 is taken as an example).

The host module 210 of the present embodiment includes a first housing 212, a processing unit 216, an omnidirectional antenna 218, and a host communication unit 214. The first housing 212 has a bearing surface (not shown in fig. 3A) similar to the first housing 112, and the first electrical interface 215 is disposed on the bearing surface. The processing unit 216 is connected to the first power interface 215, and the host communication unit 214 generates the host signal 213.

The handset module 220 of the present embodiment includes a second housing 222, a first directional antenna 226, a second directional antenna 228, and a handset communication unit 224. The second housing 222 has a second power interface 225 adapted to electrically connect with the first power interface 215 of the host module 210.

Referring to fig. 3A, when the carrying surface carries the second housing 222, the processing unit 216 determines a connection status of the first electrical interface 215 and the second electrical interface 225. When the processing unit 216 determines that the first power interface 215 is connected to the second power interface 225, the host signal 213 provided by the host communication unit 214 can be transmitted to the handset communication unit 224 through the first power interface 215 and the second power interface 225 in sequence, in addition to being transmitted through the omnidirectional antenna 218. The handset communication unit 224 converts the host signal 213 into a handset signal 221, and transmits the handset signal 221 through the first directional antenna 226. The first directional antenna 226 of the present embodiment, for example, emits the handset signal 221 along the first direction d5, that is, the strength of the handset signal 221 emitted by the first directional antenna 226 in the first direction d5 is higher than that in other directions.

Referring to fig. 3B, when the sub-module 220 is far away from the carrying surface (i.e. the first power interface 215 and the second power interface 225 are not in contact with each other), the host signal 213 is transmitted through the omni-directional antenna 218 and received by the second directional antenna 228. The handset communication unit 224 receives the host signal 213 and converts it into a handset signal 221, which is transmitted by the first directional antenna 226. In detail, for example, when detecting that there is no electrical connection between the first power interface 215 and the second power interface 225, the processing unit 216 of the embodiment controls the host communication unit 214 to send the host signal 213 to be transmitted to the sub-module 220 through the omnidirectional antenna 218, so that the sub-module 220 can receive the host signal 213 through the second directional antenna 228.

Fig. 4 is a schematic diagram of a host module and a sub-module of a wireless communication device according to a third embodiment of the invention. Referring to fig. 4, the host module 310 of the wireless communication device 300 according to the third embodiment of the present invention includes a processing unit 316, a host communication unit 314, and an omnidirectional antenna 318 similar to the above-mentioned embodiments. The host module 310 of the present embodiment further includes a first power unit 315 and a connection detection unit 317, wherein the first power unit 315 is connected to the external power source 50. The connection detecting unit 317 provides a first electrical interface on the carrying surface. The processing unit 316 is connected to the first power unit 315 and the connection detection unit 317.

The handset module 320 of the present embodiment includes a handset communication unit 324, a first directional antenna 326 and a second directional antenna 328, similar to the handset modules of the previous embodiments. The handset module 320 of the present embodiment further includes a second power unit 329, a handset display unit 325 and an antenna control unit 327.

In detail, the second power unit 323 of the present embodiment is disposed in the second casing 322, and the second power unit 323 has a second power interface disposed on a surface of the second casing 322. The second housing 322 further includes a first directional antenna 326, a second directional antenna 328, and a handset communication unit 324. The second power unit 323 is electrically connected to the first directional antenna 326, the second directional antenna 328 and the handset communication unit 324.

For example, the second power interface can be implemented as the second power interface 225 in the second embodiment, but the invention is not limited thereto, and is represented by the power connection 302 for simplifying the drawing. In other words, when the daughter module 320 of the present embodiment is disposed on the host module 310, the power connection 302 of the present embodiment is implemented by the second power interface.

When the sub-machine module 320 of the present embodiment is placed on the carrying surface, the first power interface is electrically connected to the second power interface (i.e. the power connection 302 is formed); the connection detecting unit 317 transmits a connection signal to the processing unit 316; the processing unit 316 conducts the electrical connection between the first power interface and the first power unit 315 according to the connection signal. The second power unit 323 obtains and stores power from the external power source 50 through the second power interface, the first power interface, and the first power unit 315. In other words, when the processing unit 316 receives the connection signal, the processing unit 316 conducts the first power interface and the first power unit 315 to form the power connection 302 between the host module 310 and the sub-module 320. Fig. 4 does not show the first power interface and the second power interface, but the connection relationship thereof can refer to the above embodiments, which will be further exemplified below, and will not be described herein again.

On the other hand, the sub-unit display unit 325 of the present embodiment is used to display the power status stored in the second power unit 323 and the intensity of the host signal 313 provided by the host communication unit 314 at the position of the sub-unit module 320. The sub-Display unit 325 may include a Liquid Crystal Display (LCD) Module, a Light Emitting Diode (LED) Module, and other Display modules, for example, but the invention is not limited thereto. The sub-device display unit 325 is used for displaying images or indication marks (Indicating Symbols) outside the second housing 322 of the sub-device module 320, so that the user can clearly know the power of the sub-device module 320 and the intensity of the host signal 313. In other words, in the embodiments of the present invention, the sub-module may include the indicating unit (for example, implemented by a lamp with a specific symbol) or the sub-display unit (for example, implemented by a specific display module), and in some embodiments, the sub-module may further include both the indicating unit and the sub-display unit, which is not limited in the present invention. Or, the indicating unit includes at least one of a sub-machine display unit (for example, implemented by a specific display module) and a unit module with indicating function implemented by a lamp number of a specific symbol, for example.

As the host module 210 in the second embodiment, the host module 310 in the third embodiment of the invention further includes an omnidirectional antenna 318. The host communication unit 314 transmits the host signal 313 via the omni-directional antenna 318. In other words, for the plane on which the host module 210 is placed, the host signal 313 emitted by the omni-directional antenna 318 of the host module 210 is substantially uniformly radiated on the plane, and the intensity is not concentrated in any one direction.

In the embodiment, when the sub-host module 320 is placed on the host module 310, the signal connection 301 between the host module 310 and the sub-host module 320 can be implemented by the first power contact of the host module 310 and the second power contact of the sub-host module 320. Therefore, when the sub-unit module 320 is placed on the main unit module 310, the main unit signal 313 can be transmitted to the sub-unit module 320 through the first power contact and the second power contact, and then the sub-unit communication unit 324 converts the main unit signal into the sub-unit signal 321 to be transmitted through the first directional antenna.

On the other hand, when the sub-unit module 320 is far away from the host unit 310, the signal connection 301 between the host unit 310 and the sub-unit module 320 can be implemented by the omni-directional antenna 318 and the second directional antenna 328. In other words, the host signal 313 can be received by the second directional antenna 328 and transmitted to the handset communication unit 324, and then converted into the handset signal 321 by the handset communication unit 324 and transmitted through the first directional antenna 326.

On the other hand, the antenna control unit 327 of the wireless communication device 300 according to the third embodiment of the present invention can also change the directions of the first directional antenna 326 and the second directional antenna 328. Specifically, the first directional antenna 326 of the present embodiment can substantially transmit the handset signal 326 along the first direction d6, and the second directional antenna 328 can substantially receive the host signal 313 along the second direction. The antenna control unit 327 is connected to the first directional antenna 326 and the second directional antenna 328, and can change an angle between the two directional antennas, so as to further adjust a receiving direction of the host signal 313 and a transmitting direction of the handset signal 321.

The following will further refer to the wireless communication module 100 in the first embodiment. Fig. 5A is a schematic diagram of a sub-unit module according to a first embodiment of the invention. Referring to fig. 5A, the handset module 120A includes the second housing 122A and the handset communication unit 124A. The sub-module 120A of the present embodiment further includes a display surface 1201A and a connection surface 1202A in the second housing 122A, wherein the display surface 1201A1 of the present embodiment faces away from the connection surface 1202A, but the invention is not limited thereto. In other embodiments, the display surface of the second housing of the sub-assembly module can be adjusted to face different directions according to the requirement, depending on the shape of the second housing 122A of the sub-assembly module 120A.
