[0003] 1. Bluetooth transmission with 2.4G transmission;

[0004] 2.Bluetooth transmission combined with wired USB transmission.

[0005] However, the first design is mainly designed to be small and easy to carry because the 2.4G wireless receiver is convenient to place in the keyboard and mouse, but the disadvantage is that it is easy to lose. In addition, the 2.4G wireless receiver has always been directly plugged into the USB connection port of the computer device, which makes the radio frequency of the 2.4G wireless receiver interfered by USB3.0, resulting in the attenuation of the receiving distance and the problem of radio frequency packet loss. As for the second design, the keyboard and mouse must have built-in wired USB wired connection units, and the price will also increase. In view of this, an improved input device set and a system using the input device set are urgently needed. Summary of the invention

[0040] Figure 1A Schematic diagram of the input device set and the system 1 using the input device set provided by the present invention. Figure 1B for Figure 1A Block diagram of an input device group and a system 1 that applies the input device group. FIG. 2A to FIG. 2C It is a schematic diagram of an input device set and a system 1 using the input device set switching from a first connection mode to a second connection mode according to an embodiment of the present invention. FIG. 3A to FIG. 3C It is a schematic diagram of an input device set and a system 1 using the input device set switching from a first connection mode to a second connection mode according to another embodiment of the present invention.

[0041] See also Figure 1A The system 1 using the input device set of the present invention includes: a first input device 10 , a second input device 20 , a computer device 30 and a wireless receiver 40 .

[0042] Please read further Figure 1BThe first input device 10 includes a first control element 11, and the first control element 11 has a first wireless connection unit 111, a wired connection unit 112, a pre-built-in program 113, and a first identification code 114. The second input device 20 includes a second control element 21, and the second control element 21 has a second wireless connection unit 211 and a pre-built-in second identification code 212. The first identification code 114 and the second identification code 212 are unique identification codes representing the first input device 10 and the second input device 20. The first identification code 114 and the second identification code 212 are set to match each other, and can be set to be the same, for example: the first identification code 114 is 1234, and the second identification code 212 is also 1234. They can also be set in a group, for example: the first identification code is 1234, and the second identification code is 5678, but it is not limited thereto. In this embodiment, the first input device 10 is a keyboard, the second input device 20 is a mouse, the first control element 11 and the second control element 21 are microcontrollers (MCU), the first wireless connection unit 111 and the second wireless connection unit 211 are Bluetooth wireless connection units, the wired connection unit 112 is a USB wired connection unit, and the program 113 is used to convert the first input device 10 from a peripheral device to a central (Central / Master) device, so that the first input device 10 can receive the wireless signal transmitted by the second input device 20. Although this embodiment only proposes that the first input device 10 is a keyboard and the second input device 20 is a mouse, in actual application, the first input device 10 and the second input device 20 can also be other known input device combinations, such as: a keyboard with a touchpad, or a handwriting tablet with a mouse.

[0043] The computer device 30 includes an electrical interface 31, and the wireless receiver 40 is detachably installed on the electrical interface 31, but is not limited to this. In actual application, the wireless receiver 40 can also be built into the computer device 30, wherein the electrical interface 31 is a universal serial bus (USB) connection port, and the wireless receiver 40 is a Bluetooth receiver. In this embodiment, the computer device 30 is a desktop computer or a laptop computer, but is not limited to this.

[0044] Please also read Figure 1B and FIG. 2A to FIG. 2C The system 1 of the present invention using the input device group has a first connection mode and a second connection mode. FIG. 2A to FIG. 2C A schematic diagram of switching from a first connection mode to a second connection mode. Figure 2AThis is the first connection mode. In the first connection mode, the first input device 10 communicates with the computer device 30 via wireless signals through the first wireless connection unit 111 and the wireless receiver 40, and the second input device 20 communicates with the computer device 30 via wireless signals through the second wireless connection unit 21 and the wireless receiver 40. In this way, the user can directly control the computer device 30 using the wireless signals output by the first input device 10 and the second input device 20.

[0045] like Figure 2B As shown, when the wireless receiver 40 is removed from the electrical interface 31, the first input device 10 and the second input device 20 terminate the wireless signal communication with the computer device 30. The user couples the first input device 10 to the electrical interface 31 with a transmission line, and the first input device 10 communicates with the computer device 30 through the wired connection unit 112. At the same time, the first control unit 11 executes the program 113 to convert the first input device 10 from a peripheral device to a central device, so that the first input device 10 can receive the wireless signal transmitted by the second input device 20. After the first input device 10 and the second input device 20 complete the pairing by exchanging the first identification code 114 and the second identification code 212, the two communicate with the first wireless connection unit 111 through the second wireless connection unit 211. In this way, Figure 2C As shown, the present invention enters the second connection mode. In the second connection mode, the first input device 10 directly controls the computer device 30 with a wired signal, and the second input device 20 first sends a wireless signal to the first input device 10, and then controls the computer device 30 with a wired signal through the first input device 10.

[0046] Please also read Figure 1B and Figure 2C , the first control element 11 further includes a first input module 115, and the second control element 21 further includes a second input module 213. The first input module 115 is used to allow the user to operate to input control signals such as text and numbers to the computer device 30, and the second input module 213 is used to allow the user to operate to input control signals such as XYZ axis and scrolling to the computer device 30. When the system 1 of the input device group of the present invention is applied in the second connection mode, the wired control signal of the first input device 10 will be transmitted to the computer device 30 through the wired connection unit 112 and controlled, and the second input device 20 will first transmit the wireless control signal to the first input device 10 through the second wireless connection unit 211 and the first wireless connection unit 111, and then converted into a wired control signal by the first control element 11, and further transmitted to the computer device 30 through the wired connection unit 112 and controlled.

[0047] Please also read Figure 1B and FIG. 3A to FIG. 3C , FIG. 3A to FIG. 3C Schematic diagram of an input device set and a system 1 using the input device set switching from a first connection mode to a second connection mode according to another embodiment of the present invention. The present embodiment is substantially similar to the previous embodiment in structure, with the only difference being that in the present embodiment, the second input device 20 further includes a switch 22, the switch 22 is coupled to the second control element 21, and the computer device 30 is a desktop computer or a laptop computer with a built-in wireless receiver 40. Figure 3A This is the first connection mode of this embodiment. Similar to the previous embodiment, the first input device 10 communicates with the computer device 30 via the first wireless connection unit 111 and the wireless receiver 40, and the second input device 20 communicates with the computer device 30 via the second wireless connection unit 21 and the wireless receiver 40. Figure 3B When the user couples the first input device 10 to the electrical interface 31 with a transmission line, the first input device 10 stops communicating with the computer device 30 through wireless signals, and instead communicates with the computer device 30 through wired signals via the wired connection unit 112. At the same time, the first control unit 11 executes the program 113 to convert the first input device 10 from a peripheral device to a central / master device, so that the first input device 10 can receive the wireless signal transmitted by the second input device 20. At this time, the second input device 20 still maintains wireless signal communication with the computer device 30. The first input device 10 and the second input device 20 exchange the first identification code 114 and the second identification code 212 to complete pairing. The user can further operate the switch 22 to allow the second input device 20 to selectively communicate with the first input device 10 through the second wireless connection unit 211 and the first wireless connection unit 111. In this way, Figure 3C As shown, the system 1 using the input device group of this embodiment enters the second connection mode. The advantage of this embodiment is that when the computer device 30 communicates with multiple peripheral devices (such as wireless headphones, wireless mice, wireless keyboards, etc.) through the wireless receiver 40 at the same time, there is often a response delay due to processing too many signals at the same time. At this time, the signal communication path of some peripheral devices can be changed through the method of this embodiment, thereby improving the delay problem.

[0048] Although the present invention only proposes an implementation mode in which the first wireless connection unit 111 and the second wireless connection unit 211 are Bluetooth wireless connection units and the wired connection unit 112 is a USB wired connection unit, in actual applications, the first wireless connection unit 111 and the second wireless connection unit 211 may also be other known wireless connection units, and the wired connection unit 112 may also be other known wired connection units, and the implementation mode is not limited to the implementation mode proposed by the present invention.

[0049] In summary, the input device set and the system using the input device set provided by the present invention have the following advantages:

[0050] 1. First, since the first input device 10 and the second input device 20 no longer need to be connected to the computer device 30 via an additional 2.4G wireless receiver, the user no longer needs to worry about losing the 2.4G wireless receiver. In addition, since there is no need to transmit data via 2.4G wireless transmission technology, the first input device 10 and the second input device 20 do not need to establish a 2.4G wireless transmission protocol in the device, effectively reducing costs.

[0051] 2. Furthermore, since there is no 2.4G wireless receiver plugged into the USB connection port, and the first input device 10 is separated from the USB connection port by a transmission line, the problem of shielding interference is solved.

[0052] 3. The input device set of the present invention only needs to select one of the input devices to be added to the USB wired connection unit, which not only effectively reduces the cost but also simplifies the complexity of the device.

[0053] The present invention effectively solves the problem that when multiple input devices communicate with a computer device, an additional receiver needs to be connected and data packets are lost, which causes inconvenience.

[0054] However, the above is only a preferred embodiment of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. That is, all simple equivalent changes and modifications made according to the claims of the present invention and the content of the invention description are still within the scope of the patent of the present invention. In addition, any embodiment or claim of the present invention does not have to achieve all the purposes, advantages or features disclosed in the present invention. In addition, the abstract and the title are only used to assist in the search of patent documents, and are not used to limit the scope of rights of the present invention. In addition, the terms "first", "second", etc. mentioned in this specification or claims are only used to name the name of the element or distinguish different embodiments or scopes, and are not used to limit the upper or lower limit of the number of elements.
