Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 This utility model provides a key vibration feedback keyboard, including a keyboard body 1, which is composed of an aluminum alloy back shell 4 and a touch panel 2. The touch panel 2 is disposed on the aluminum alloy back shell 4 and is a glass touch panel. The surface of the touch panel 2 is provided with a character pressing area 3, and a pressure sensor is provided for each character in the character pressing area 3. A linear motor is provided on the keyboard body 1. A protective shell 6 and a protective shell 7 are respectively installed on both sides of the aluminum alloy back shell 4. Both the protective shell 6 and the protective shell 7 are detachably installed on both sides of the aluminum alloy back shell 4.

[0028] See Figure 1 A keyboard circuit is set between the aluminum alloy back shell 4 and the touch panel 2. A status display screen 5 is set on the keyboard body 1.

The keyboard body 1 is equipped with dual-mode Bluetooth, a keyboard power button and a keyboard backlight brightness adjustment button.

[0029] The keyboard circuit includes a pressure sensor, memory, processor, backlight, and battery. Multiple characters are correspondingly set in the character pressing area. These characters refer to English letters, numbers, and symbols on a traditional keyboard. Each character pressing area 107 has a pressure sensor that can recognize the pressing action of the character pressing area. That is, when a user presses a character in the pressing area, the corresponding pressure sensor will recognize the pressing action and generate the corresponding key value. Generating corresponding key values ​​based on pressing actions is existing technology and will not be elaborated further. The pressure sensor is an electromagnetic pressure sensor, which is also existing technology and will not be elaborated further.

[0030] The status display screen is used to show the keyboard battery level, letter Caps Lock status, and keyboard backlight brightness level. The status display screen is an OLED display, capable of showing the keyboard battery level, letter Caps Lock status, and keyboard backlight brightness level, etc. In addition to displaying information, the status display screen 104 can also be used for handwriting input. The status display screen allows the keyboard to display more information. The internal circuit uses a rechargeable battery with a Type-C charging interface, a charging power of 10W, and a battery capacity of 500mAh. Specifically, the portable foldable keyboard of this invention has a built-in rechargeable battery with a capacity of 500mAh. The keyboard enters sleep mode when not in use for fixed time intervals; sleep mode refers to a low-power state. The user can wake it up by pressing a key. Dual-mode Bluetooth is a common type of Bluetooth, which can simultaneously support traditional Bluetooth and Bluetooth Low Energy, providing better compatibility. A linear motor is used to vibrate when a pressing action is performed.

[0031] See Figure 1-4Both protective shell 6 and protective shell 7 have an L-shaped connecting plate 8 fixedly installed at one end facing the keyboard body 1. Both ends of the L-shaped connecting plate 8 have protruding round rods 9. Two mounting slots 10 are formed inside the L-shaped connecting plate 8, and connecting rods 11 connecting the round rods 9 are installed in the mounting slots 10. A reset assembly is fixed between the other end of the connecting rod 11 and the inner wall of the mounting slot 10. A snap-fit ​​plate 19 is fixedly installed at the top of protective shell 6 with screws. A secondary snap-fit ​​plate 20 is fixedly installed at the top of protective shell 7 with screws. A protruding secondary round rod 21 is installed on the snap-fit ​​plate 19. A secondary mounting slot is formed inside the snap-fit ​​plate 19, and a secondary reset assembly is installed in the secondary mounting slot. The secondary reset assembly connects to the secondary round rod 21. Both the secondary reset assembly and the reset assembly include a reset spring 12 and a telescopic rod 13. The telescopic rod 13 is located inside the reset spring 12. Both ends of the reset spring 12 and the telescopic rod 13 are fixedly installed with... A fixed plate is fixed to the end of the connecting rod 11 and the inner wall of the setting groove 10. A vertical rod 14 is fixed to the bottom end of the connecting rod 11, and a vertical rod 25 is fixed to the top end of the connecting rod 11. A horizontal sliding groove 16 is opened at the bottom end of the setting groove 10. The bottom of the vertical rod 14 extends into the horizontal sliding groove 16. A secondary horizontal sliding groove 17 is opened on the L-shaped connecting plate 8. The top of the vertical rod 25 extends into the secondary horizontal sliding groove 17. A manual push plate 18 is fixed to the top end of the vertical rod 25. The manual push plate 18 is slidably set on the top surface of the snap-fit ​​plate 19 and the outer surface of the L-shaped connecting plate 8. An insertion round hole is opened on the end face of the secondary snap-fit ​​plate 20 facing the secondary round rod 21. Two square blocks 22 are fixed on both sides of the keyboard body 1. A secondary insertion round hole is opened on the square blocks 22. Soft rubber sealing gaskets 23 are pasted on the bottom end face and the opposite end face of the protective shell 1 6 and the protective shell 2 7.

[0032] When installing protective shell 1 (6), protective shell 2 (7), and the corresponding block 22, personnel can manually press and hold the manual push plate 18 and push it to move on the outer surface of the L-shaped connecting plate 8. Figure 3 By pushing the two manual push plates 18 closer together, the vertical rods 15 move in the same direction. The two vertical rods 15 then compress the connected return spring 12, causing the round rods 9 to retract inwards. This allows the L-shaped connecting plate 8 to insert between the two blocks 22. Releasing the manual push plates 18 resets the return spring 12, ultimately causing the round rods 9 to move and insert into the secondary insertion hole of the block 22. This allows the protective shells 6 and 7 to be installed at both ends of the keyboard. When the keyboard is not in use, the protective shells 6 and 7 can be flipped over, merging to form a single protective shell that covers the keyboard surface, effectively preventing dust. Furthermore, subsequent disassembly also provides good protection for the touch keys, preventing them from being bumped or damaged. Figure 3The diagram only shows one setting slot 10, which has two setting slots 10, each containing a reset component connected to a corresponding round rod 9. A manual push plate 18 is not connected to the second vertical rod 15; this is to avoid obstructing the view of the secondary horizontal slide groove 17. The secondary reset component and the reset component have the same design. Through the same operation described above, the secondary round rod 21 can be inserted into the insertion hole of the secondary snap-fit ​​plate 20. Therefore, the first protective shell 6 and the second protective shell 7 form a complete protective shell, which also has a carrying handle, ensuring convenient keyboard portability. The rubber sealing gasket 23 ensures a good seal on the panel, providing excellent dust protection. The joint of the protective shell also has a rubber sealing gasket 23, ensuring a good seal after connection. The soft rubber sealing gasket 23 better conforms to the touch panel. When the keyboard has a keyboard cable, it can also be stored inside the closed protective shell. Even if the keyboard cable is squeezed by the soft rubber sealing gasket 23, it will not damage the keyboard cable.

[0033] In use, pressure sensors are set for the characters corresponding to the character pressing area 3. The pressure sensors are used to identify the pressing action of the character pressing area. That is, when the user presses the character pressing area, the corresponding pressure sensor will identify the pressing action and generate the corresponding key value. A linear motor is used to vibrate when the pressing action is effective. The character pressing area is set on the glass touch panel. When the user presses the character pressing area, if the pressing action is effective, the linear motor will vibrate to provide operation feedback. Through the design of protective shell 6 and protective shell 7, protective shell 6 and protective shell 7 can be combined to form a complete protective shell, which effectively covers the character pressing area 3 on the glass touch panel, that is, the entire glass touch panel. Therefore, the keyboard is easy to protect against dust. When placed for a long time, the keyboard surface is not easy to accumulate dust, and it does not affect the use of subsequent users. This utility model has a simple design and effectively provides better protection for the keyboard panel.

[0034] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
