Embodiment 1

[0031] Embodiment one, with reference to Figure 1-3As shown, this embodiment provides a mechanical key, including a keycap 10, a shaft core 40, a housing 30, and a lower cover 21, the keycap 10 is assembled above the shaft core 40, and the housing 30 surrounds the Around the shaft core 40 and limit the shaft core 40, the lower cover 21 is arranged below the shaft core 40, and a micro-motion sensing sheet 70 is laid above the lower cover 21, and the micro-motion sensing sheet An elastic piece is arranged above the 70, and the elastic piece adopts a trumpet-shaped spring 50 with a thin upper part and a thicker lower part. The positioning plate 60 is provided with a positioning hole for the spring to pass through, and the lower end of the housing 30 presses against the positioning plate 60 . According to the above-mentioned technical scheme, the micro-motion sensing sheet 70 is used to transmit the button action signal, and the micro-motion sensing sheet 70 sends the signal thr...

Embodiment 2

[0037] Embodiment two, refer to Figure 1-3 As shown, the present embodiment adopts the above-mentioned mechanical keys and provides a keyboard, including an upper cover 2 and a middle plate 3. The shell 30 is arranged on the middle plate 3 according to the distribution of the keyboard keys. The positioning plate 60 of the button, the micro-motion sensing sheet 70, the light guide plate 80, the weight plate 90 and the lower cover 21 are connected as a whole to form a plate-shaped integral assembly, forming the positioning plate assembly 6, the micro-motion induction sheet assembly 7, and the light guide plate assembly 8 , the weight plate assembly 9 and the lower cover assembly 20. According to the above technical solution, by integrating the outer shell 30 with the middle plate 3, a new combination mode is formed, which eliminates the need for positioning and installation of the shaft core components one by one in the prior art . The shells 30 are connected as a whole, and ...

Embodiment 3

[0041] Embodiment three, refer to image 3 and Figure 4 As shown, the present invention also provides a method for assembling a keyboard, using the mechanical keys and the components in the keyboard, and a top plate needs to be prepared as an assembly aid before assembly, such as Figure 4 As shown, the top board has protrusions corresponding to the housing on the middle board, and the assembly steps are:

[0042] S1, turn the middle plate 3 over, put the shaft core 40 into the shell 30 on the middle plate 3 after turning it over, make the upper part of the shaft core 40 pass through the through hole in the upper part of the shell 30, exposing the top of the shaft core 40;

[0043] S2, align the protrusion of the top plate with the lower part of the shaft core 40 to jack up the shaft core 40, then turn the top plate together with the shaft core 40 and the middle plate 3 by 180 degrees, and then place the keycap 10 Wear the shaft core 40 to expose the top of the shell 30, c...

Abstract

The invention provides a mechanical key which comprises a key cap, a central spindle, a shell and a lower cover. The key cap is assembled above the central spindle, the periphery of the central spindle is enclosed by the shell, the central spindle is limited by the shell, the lower cover is arranged below the central spindle, a micro-movement sensing sheet is laid above the lower cover, an elastic element is arranged above the micro-movement sensing sheet, the upper side of the elastic element is connected with the central spindle, a positioning plate is arranged on the upper side of the micro-movement sensing sheet, a positioning hole is formed in the positioning plate, the elastic element can penetrate the positioning hole, and the lower end of the shell is butted to the positioning plate. The mechanical key has the advantages that action signals of the key can be transmitted by the micro-movement sensing sheet, a variable generated by the action signals can be used as a command to be outwardly transmitted, consideration on continuous pushing of a pushing component is omitted, accordingly, continuous pushing running spaces can be provided for the elastic element, and hand feel effects of the mechanical key can be realized.

Description

technical field [0001] The invention belongs to the technical field of keys for electronic command input devices, and in particular relates to mechanical keys, keyboards and assembly methods thereof. Background technique [0002] At present, computer keyboards mostly use a combination structure of a single key switch. A single key is usually composed of a keycap, a push rod, a silicone elastic piece and a thin film circuit. The thin-film circuit is set under the silicone elastic piece. When in use, the push rod is pressed down by pressing the keycap, and then pressed down on the thin-film circuit through the silicone elastic piece, so that the thin-film circuit is turned on, thereby When the input effect is reached, let go of the keycap, and under the elastic force of the silicone elastic piece, the push rod goes up to disconnect the membrane circuit. The button with this structure has only two states, one is off and the other is on. After the push rod is turned on, there i...
