Description

Technical Field

[0001] This utility model relates to the field of computer accessories technology, specifically to a multi-functional keyboard based on a spring. Background Technology

[0002] A keyboard is a data input device used to operate a computer system. Through the keyboard, English letters, numbers, punctuation marks, etc., can be entered into the computer, thereby issuing commands and inputting data.

[0003] When a traditional keyboard is subjected to external impact or prolonged use, the circuit board may shift slightly in its mounting position due to insecure mounting. This movement can cause additional stress on connected wires or connectors, increasing the risk of damage. Furthermore, an unstable circuit board can affect the tactile feedback of the keys, degrading the user experience. Therefore, this invention proposes a multi-functional keyboard based on a spring-loaded contact. Utility Model Content

[0004] The purpose of this invention is to provide a multi-functional keyboard based on a spring-loaded contact spring, addressing the issue raised in the background section where, in traditional keyboards, the circuit board may experience slight movement in its mounting position due to insecure fixation when subjected to external impact or prolonged use. This movement can cause additional stress on connected wires or connectors, increasing the risk of damage. Furthermore, an unstable circuit board can affect the tactile feedback of the keys, reducing the user experience.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-functional keyboard based on a spring sheet includes a keyboard body, which includes an upper shell and a bottom shell that are detachably connected. An irregular encapsulation groove is formed on the inner side of the upper shell, a first mounting hole is formed on the bottom side of the bottom shell, and a mounting groove is formed on the other side of the bottom shell opposite to the first mounting hole. A circuit board is installed inside the bottom shell, and a plurality of unevenly distributed positioning rods are provided on the upper surface of the circuit board. A positioning plate of the same size is installed above the circuit board.

[0007] Optionally, the positioning plate is provided with several mounting ears on its upper and lower sides, and the bottom of the mounting ears is provided with a rod. The end face of the positioning plate is provided with a positioning hole that cooperates with the positioning rod.

[0008] Optionally, a support column is installed on the first mounting hole, and a fixing plate is pressed on the support column.

[0009] Optionally, the insertion rod is detachably connected to the bottom shell by passing through a fixing plate and a support column.

[0010] Optionally, a plastic part is installed on the side of the bottom shell in relation to the mounting groove. The upper side of the plastic part is provided with a second mounting hole arranged in the same manner as the first mounting hole. The second mounting hole is provided with a support column and a fixing plate of the same components.

[0011] Optionally, the insertion rod on the other side of the positioning plate is fixedly connected to the plastic part through a support column and a fixing plate installed on the second mounting hole.

[0012] Optionally, the outer surface of the bottom shell is fitted with a ribbon.

[0013] The beneficial effects of this utility model are:

[0014] 1. In this utility model, by using the positioning rod and positioning hole between the positioning plate and the circuit board, and the fixing method of the fixing plate and support column through the insertion rod on the upper and lower sides of the positioning plate, the circuit board is stably fixed inside the keyboard. This structure can not only effectively prevent the minor movement of the circuit board when the keyboard is subjected to external impact or long-term use, but also greatly reduce the additional stress caused by the shaking of the circuit board to the wires or connectors, thereby significantly improving the overall durability and service life of the keyboard.

[0015] 2. The keyboard structure of this utility model adopts a detachable upper shell and lower shell design, as well as a quick fixing method between the circuit board and the positioning plate through the plug rod and support column. This not only makes the keyboard assembly process simpler and faster, but also makes it convenient for users to disassemble and maintain the keyboard when needed. Attached Figure Description

The upper shell 101 and the bottom shell 102 are detachably connected. An irregular encapsulation groove 1011 is provided on the inner side of the upper shell 101. A first mounting hole 1021 is provided on the bottom side of the bottom shell 102. A mounting groove 1022 is provided on the other side of the bottom shell 102 about the first mounting hole 1021. A circuit board 3 is installed inside the bottom shell 102. Several unevenly distributed positioning rods 301 are provided on the upper surface of the circuit board 3. A positioning plate 2 of the same size is installed on the top of the circuit board 3.

[0027] Furthermore, the upper and lower sides of the positioning plate 2 are provided with several mounting ears 201, the bottom of the mounting ears 201 is provided with a rod 202, and the end face of the positioning plate 2 is provided with a positioning hole 203 that cooperates with the positioning rod 301.

[0028] Furthermore, a support column 4 is installed on the first mounting hole 1021, and a fixing piece 5 is pressed on the support column 4.
