[0034] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.
[0035] Please see Figures 1 to 5 This utility model discloses a key with dynamic display function, including keycaps, switches, PCB board 30, terminals 40 and metal springs 41.
[0036] like Figure 1 and Figure 2 As shown, the keycap includes an outer keycap layer 10, an inner keycap layer 11, and a display screen 12. The top of the outer keycap layer 10 has a display section 101, and the display screen 12 is sandwiched between the top surface of the outer keycap layer 10 and the top surface of the inner keycap layer 11, with the display section 101 and the display screen 12 facing each other vertically.
[0037] The switch includes a switch cover 20, a switch seat 21, a switch core, and a resilient reset element 23. The switch cover 20 and the switch seat 21 are fastened together and together form an assembly cavity. The resilient reset element 23 is disposed in the assembly cavity and can extend and retract in the vertical direction. The top end of the switch core is embedded in the inner layer 11 of the keycap, and the bottom end of the switch core moves through the switch cover 20 and abuts against the top end of the resilient reset element 23. The side wall of the switch core is provided with a trigger part 224. The PCB board 30 is detachably electrically connected to the display screen 12 through the screen cable 121. The PCB board 30 is embedded with a switch connector 31. The terminal 40 and the metal spring 41 are disposed opposite each other in the assembly cavity. The pins 42 of the terminal 40 and the metal spring 41 are fixedly inserted through the switch seat 21 and snapped into the switch connector 31. The contact point 43 of the terminal 40 and the contact point 43 of the metal spring 41 are connected or disconnected under the drive of the trigger part 224 of the switch core to complete the transmission of the key signal.
[0038] This invention discloses a button with dynamic display function. A display screen 12 is installed between the outer layer 10 and the inner layer 11 of the keycap. The display screen 12 is electrically connected to the PCB board 30, giving the button a dynamic display function. This allows users to intuitively and conveniently obtain the characters, shortcut keys, and icon information represented by the button according to different usage scenarios. Compared with traditional static buttons, this greatly improves the button's functionality and user interaction experience. The pins 42 of the terminal 40 and the metal spring 41 are snapped into the shaft connector 31, achieving a detachable connection. This allows users to easily replace or upgrade the button according to their needs, thereby extending the button's lifespan and providing users with space for personalized customization.
[0039] In the embodiments of this utility model, the display unit 101 is non-transparent when the display screen 12 is in a power-off and screen-off state, and is transparent when the display screen 12 is powered on and the screen is lit. Specifically, the display unit 101 adopts a liquid crystal dimming film. The display unit 101 becomes transparent after the display screen 12 is lit, thereby clearly revealing the content of the display screen 12. When the display screen 12 is off, it is black. The display unit 101 with this feature can completely hide the input content of the buttons in public places when the screen is off, effectively protecting the user's privacy information and avoiding information leakage.
[0040] In this embodiment of the invention, a light-shielding sheet 13 is also sandwiched between the top surface of the outer layer 10 of the keycap and the top surface of the inner layer 11 of the keycap. The light-shielding sheet 13 covers the non-effective display area of the display screen 12, so that the effective pixel area of the display unit 101 and the non-effective display area are physically isolated from each other. This effectively reduces the light leakage phenomenon in the non-effective display area of the display screen 12, improves the contrast and clarity of the display screen, and makes the display effect of the display unit 101 purer and more beautiful, bringing users a better visual experience.
[0041] In the embodiments of this utility model, a positioning pin 211 is provided at the center of the bottom surface of the shaft seat 21, and a positioning hole 301 that cooperates with the positioning pin 211 is provided at the center of the PCB board 30. By cooperating with the positioning pin 211 and the positioning hole 301, the relative position between the shaft and the PCB board 30 can be ensured to be accurate and error-free, thus ensuring the accuracy and stability of the installation.
[0042] like Figure 2As shown in Figure 5, in this embodiment of the present invention, the spindle includes a spindle body 221, guide strips 222 fixed on both sides of the spindle body 221, and an anti-rotation insertion part 223 fixed on the top of the spindle body 221. The anti-rotation insertion part 223 is a cross-shaped protrusion. The inner side of the top of the keycap inner layer 11 is provided with a connecting groove 111 that engages with the anti-rotation insertion part 223. The connecting groove 111 is a cross-shaped groove structure. The cross-shaped protrusion and the cross-shaped groove structure are connected to the spindle and the keycap as a whole by an interference fit. The spindle seat 21 is provided with two guide grooves 213 that slide with the two guide strips 222. By cooperating with the guide strips 222 and the guide grooves 213, it is ensured that the spindle can only move in a preset manner, thereby ensuring the consistency and stability of the key trigger action and effectively improving the key feel and reliability.
[0043] like Figure 3 and Figure 4 As shown, in an embodiment of the utility model, the trigger portion 224 of the shaft core is located on the side wall between the two guide bars 222. The specific structures of the terminal 40, the metal spring 41, and the trigger portion 224 are all prior art and will not be described in detail here.
[0044] In an embodiment of this utility model, a first guide post 225 is provided at the center of the bottom surface of the shaft core body 221, and a second guide post 212 is provided in the assembly cavity and coaxial with the first guide post 225. The elastic reset element 23 is a compression spring, and the two ends of the compression spring are respectively sleeved on the first guide post 225 and the second guide post 212. The first guide post 225 and the second guide post 212 limit and guide the compression spring, effectively preventing the compression spring from shifting or twisting during compression and reset.
[0045] In an embodiment of the utility model, the two outer sides of the shaft cover 20 are provided with downwardly extending elastic buckles 201, and the two outer sides of the shaft seat 21 are provided with side bosses 214.
