[0044] Please also see Figures 1 to 5 , the present invention provides a preferred embodiment of a wired tablet keyboard.

[0045] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown, a wired tablet keyboard 11 provided by the present invention comprises: a keyboard assembly 1, a protective shell 2, a first connection interface 3, a second connection interface 4 and an electrical connection assembly 5. The keyboard assembly 1 and the protective shell 2 are detachably connected through the electrical connection assembly 5; the first connection interface 3 is arranged on one side of the protective shell 2 and connected to the electrical connection assembly 5, and the first connection interface 3 is used to connect to the connection interface of a tablet computer; the second connection interface 4 is arranged on one side of the protective shell 2 and connected to the electrical connection assembly 5, and the second connection interface 4 is used to extend the function of the connection interface of the tablet computer.

[0046] In this embodiment, the wired tablet keyboard 11 is composed of two major parts: a keyboard assembly 1 and a protective shell 2. The keyboard assembly 1 uses standard USB communication. The keyboard assembly 1 is connected to the tablet computer through the electrical connection assembly 5 and the first connection interface for USB communication, and the second connection interface 4 is connected to the tablet computer through the electrical connection assembly 5. When in use, the tablet computer can be placed in the protective shell 2, and the protective shell 2 is connected to the keyboard assembly 1 through the electrical connection assembly 5. The protective shell 2 and the keyboard assembly 1 can be disassembled to facilitate the removal of the keyboard assembly 1 from the protective shell 2 when the keyboard 11 is not needed.

[0047] Generally speaking, the connection interface of a tablet computer is a TYPE-C female connector. Accordingly, the first connection interface 3 is a TYPE-C male connector; the second connection interface 4 is a TYPE-C female connector. The first connection interface 3 and the second connection interface 4 are both arranged on the side of the protective shell 2 and connected to the electrical connection component 5. In a specific implementation, the tablet computer is placed in the protective shell 2, and the connection interface of the tablet computer is connected to the first connection interface 3, so that the keyboard component 1 can be connected to the tablet computer through the electrical connection component 5, thereby realizing signal transmission between the keyboard component 1 and the tablet computer. In addition, the second connection interface 4 is connected to the electrical connection component 5, so that the connection with the tablet computer can be achieved through the electrical connection component 5. In this way, when the tablet computer needs to use the connection interface thereon to connect the keyboard 11, that is, when the connection interface of the tablet computer is occupied by the keyboard 11, the second connection interface 4 on the protective shell 2 can also be used as an extension of the connection interface of the tablet computer, thereby extending all the functions of the connection interface of the original tablet computer. For example, when the connection interface of the tablet computer is a TYPE-C connector socket, the second connection interface 4 is a TYPE-C connector socket, and the second connection interface 4 serves as an extension of the TYPE-C connector socket of the tablet computer.

[0048] In some embodiments, Figure 4 As shown, the electrical connection component 5 includes: a first flexible circuit board 51, a second flexible circuit board 52, a third flexible circuit board 53, an adapter board 54, a keyboard control board 55 and a Pogo pin component 56. The adapter board 54 is arranged on the protective shell 2 and connected to the Pogo pin component 56 through the second flexible circuit board 52; the keyboard control board 55 is arranged on the keyboard component 1 and connected to the Pogo pin component 56 through the third flexible circuit board 53; the first connection interface 3 is connected to the adapter board 54 through the first flexible circuit board 51; and the second connection interface 4 is connected to the adapter board 54.

[0049] In this embodiment, the first connection interface 3 is connected to the first flexible circuit board 51, and the second connection interface 4 is connected to the adapter board 54. The Pogo pin assembly 56 includes a Pogo pin female socket 561 and a Pogo pin male connector 562. The Pogo pin female socket 561 is installed on the protective shell 2 and connected to the adapter board 54 through the second flexible circuit board 52. The Pogo pin male connector 562 is installed on the keyboard assembly 1 and connected to one end of the third flexible circuit board 53. The other end of the third flexible circuit board 53 is connected to the keyboard control board 55.

[0050] The adapter board 54 is used as the main control board, on which a hub is integrated, and is mainly used to realize signal transfer. The keyboard control board 55 is electrically connected to the keyboard assembly 1, and can feed back the signal of the keyboard assembly 1 to the tablet computer. When the first connection interface 3 is connected to the tablet computer, the signal of the keyboard control board 55 reaches the adapter board 54 after passing through the third flexible circuit board 53, the Pogo pin assembly 56 and the second flexible circuit board 52 in sequence, and then further passes through the first flexible circuit board 51 and is transmitted to the tablet computer through the first connection interface 3. If an external device needs to be connected to the tablet computer at this time, it can be connected to the second connection interface 4 and realize data transmission through the adapter board 54, so that the second connection interface 4 can be used to achieve the purpose of extending all functions of the connection interface of the tablet computer.

[0051] In some embodiments, Figure 2 and Figure 4 As shown, the keyboard assembly 1 includes a keyboard 11 and a keyboard bracket 12. The keyboard 11 is arranged on the keyboard bracket 12; the third flexible circuit board 53 and the keyboard control board 55 are arranged on the keyboard bracket 12; and the keyboard 11 and the keyboard control board 55 are electrically connected.

[0056] In some embodiments, Figure 1 As shown, the protective shell 2 is provided with a third mounting groove 24 for mounting the adapter plate 54 , and the third mounting groove 24 is communicated with the second mounting groove 23 .

[0057] In this embodiment, a third mounting groove 24 is provided on the protective shell 2, and the adapter plate 54 is accommodated in the third mounting groove 24. Since the second connection interface 4 is connected to the adapter plate 54, the third mounting groove 24 is connected to the second mounting groove 23 to facilitate the connection between the second connection interface 4 and the adapter plate 54.

[0058] In this embodiment, a first mounting groove 22 and a second mounting groove 23 are provided on the side of the protective shell 2. The first mounting groove 22 can provide a mounting space for the first connection interface 3, and the second mounting groove 23 can provide a mounting space for the second connection interface 4. It should be noted that the first mounting groove 22 and the second mounting groove 23 are located on the same side of the protective shell 2, or on different sides of the protective shell 2.

[0059] In some embodiments, Figure 4 and Figure 5 As shown, the protective shell 2 is provided with a camera avoidance hole 25 , so that when the tablet computer is placed in the protective shell 2 , the camera of the tablet computer can also be used normally.

[0060] According to a further configuration of the present invention, the protective shell 2 is made of a plastic material. In this embodiment, the protective shell 2 is a plastic shell, which can prevent scratches from being generated between the tablet computer and the protective shell 2 due to contact.

[0061] In some embodiments, Figure 6 As shown, the present invention also provides a method for using a wired tablet keyboard, comprising the steps of:
