Description

Technical Field

[0001] This utility model relates to the field of magnetic induction scissor-switch keyboards, and particularly to a scissor-switch magnetic axis keyboard with a silicone cap as the key reset element. Background Technology

[0002] Existing scissor-switch keyboards are membrane keyboards. Firstly, they cannot achieve full key rollover. If backlighting is required, a membrane circuit for backlighting must be added, and communication with the keys is necessary for interactive backlighting and key presses. This is extremely inconvenient, and assembly is complex, increasing the overall height of the keyboard. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and to provide a scissor-switch magnetic axis keyboard with a silicone cap as the key reset element.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A scissor-switch magnetic keypad with silicone caps as key reset elements includes a scissor-switch mechanism, an overall fixing plate, keycaps, silicone caps, and a single-sided FPC made of several magnetic induction integrated circuit chips. The bottom of the scissor-switch mechanism is fixed to the overall fixing plate, and the top is fixed to the keycaps. A magnetic element is fixed below the keycaps. The silicone cap is located in the hollow part of the scissor-switch mechanism and directly below the magnetic element, used for resetting the scissor-switch mechanism and the keys. The single-sided FPC is tightly attached to the lower surface of the overall fixing plate, and the bottom of the silicone cap is supported on the upper surface of the overall fixing plate.

[0006] Pressing the keycap simultaneously compresses the magnetic component downwards, as well as the scissor-switch mechanism and silicone cap. As the keycap is pressed down, the magnetic component passes through the magnetic induction surface of the magnetic induction integrated circuit chip, causing the polarity of the chip to change. Releasing the keycap simultaneously raises the magnetic component, and the scissor-switch mechanism and silicone cap return to their original positions.

[0007] A scissor-switch magnetic keypad with a silicone cap as the key reset element includes a scissor-switch structure, an overall fixing plate, keycaps, a silicone cap with a through hole in the middle, and a single-sided FPC made of several magnetic induction integrated circuit chips. The bottom of the scissor-switch structure is fixed to the overall fixing plate, and the top is fixed to the keycap. A magnetic element is fixedly installed below the keycap. The silicone cap is located in the hollow part of the scissor-switch structure, and the magnetic element passes through the through hole of the silicone cap when not pressed. The silicone cap is used for the reset of the scissor-switch structure and the keycaps. The single-sided FPC is tightly attached to the lower surface of the overall fixing plate, and the bottom of the silicone cap is supported on the upper surface of the overall fixing plate.

[0008] Pressing the keycap simultaneously compresses the magnetic component downwards, as well as the scissor-switch mechanism and silicone cap. As the keycap is pressed down, the magnetic component passes through the magnetic induction surface of the magnetic induction integrated circuit chip, causing the polarity of the chip to change. Releasing the keycap simultaneously raises the magnetic component, and the scissor-switch mechanism and silicone cap return to their original positions.

[0009] A scissor-switch magnetic keypad with silicone caps as key reset elements includes a scissor-switch mechanism, an overall fixing plate, keycaps, silicone caps, and a single-sided FPC made of several magnetic induction integrated circuit chips.

[0012] Pressing the keycap simultaneously compresses the magnetic component downwards, as well as the scissor-switch mechanism and silicone cap. As the keycap is pressed down, the magnetic component passes through the magnetic induction surface of the magnetic induction integrated circuit chip, causing the polarity of the chip to change. Releasing the keycap simultaneously raises the magnetic component, and the scissor-switch mechanism and silicone cap return to their original positions.

[0013] Magnetic components are used as switches in magnetic induction integrated circuit chips, i.e., the outputs of digital logic 1 or 0.

[0014] The magnetic induction integrated circuit chip on a single-sided FPC uses a MagSeriLux chip. The MagSeriLux chip has built-in RGB LEDs, and its signal input and output lines are cascaded end to end, using a serial communication method. The MagSeriLux chip integrates a magnetic induction circuit and a RGB circuit. Several magnetic induction integrated circuit chips are cascaded. Each magnetic induction integrated circuit chip includes a power pin, a ground pin, a data input pin, and a data output pin. The data output pin of the magnetic induction integrated circuit chip is connected to the data input pin of the next adjacent magnetic induction integrated circuit chip, and the data input pin of the magnetic induction integrated circuit chip is connected to the data output pin of the previous adjacent magnetic induction integrated circuit chip. The connection between the data input and data output pins of several magnetic induction integrated circuit chips forms a data line. The power network VCC, ground network GND, data input network DI(1), and data output network DO(n) on the FPC are connected to an external MCU to process data information.

[0015] The magnetic induction integrated circuit chip on a single-sided FPC uses MagSyncLux chips. These chips have built-in RGB LEDs, and their power, ground, and signal lines are connected in parallel, employing addressable serial communication. Each MagSyncLux chip integrates a magnetic induction circuit and a RGB color-coding circuit. Each chip includes a power pin, a ground pin, and a data pin. The power pins of several chips are connected in parallel, sharing a common power network VCC; the ground pins are connected in parallel, sharing a common ground network GND; and the data pins are connected in parallel, sharing a common data network DIO. Data is transmitted on the data network DIO. These three networks—VCC, GND, and DIO—are connected to an external MCU for data processing on the FPC.

[0016] The magnetic induction integrated circuit chip on a single-sided FPC uses a MagVoltLux chip, which integrates RGB LEDs and uses power line carrier communication for addressable serial communication over the power line. The MagVoltLux chip integrates magnetic induction circuitry and RGB lighting circuitry. Several MagVoltLux chips are connected in parallel to the MCU on the PCB. Each MagVoltLux chip includes a power pin and a ground pin. The power pins of several MagVoltLux chips are connected in parallel to share a common power network VCC, and the ground pins are connected in parallel to share a common ground network GND. Data is modulated onto the power network VCC for transmission. The power network VCC (DIO) and the ground network GND, these two networks on the FPC, are connected to an external MCU for data processing.

[0017] Several of the aforementioned silicone caps are attached to the overall fixing plate.

[0018] The scissor-switch magnetic axis keyboard with silicone caps as key reset elements also includes a whole film, with several silicone caps distributed on the whole film. The film is provided with a first clearance hole, which is used to avoid the scissor-switch fixing slot on the overall fixing plate.

[0019] When a single-sided FPC is tightly attached to the upper surface of the overall fixing plate, the lower surface of the entire film is provided with a groove to avoid the magnetic induction integrated circuit chip.

[0020] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0021] 1. The X-type scissor-switch key is a mature key structure that is widely used in laptop keyboards or similar ultra-thin independent keyboards. This utility model improves upon it by combining a silicone cap with magnetic components, and uses a single-sided FPC (Flexible Printed Circuit) made of a magnetic color-changing magnetic induction chip, a magnetic color-changing magnetic induction chip, or a magnetic color-changing magnetic induction chip to simplify the mechanical keyboard structure, simplify the manufacturing process, and facilitate assembly.

[0022] 2. The single-sided FPCs made of magnetic color-changing magnetic induction chips, magnetic color-changing magnetic induction chips, and magnetic color-changing magnetic induction chips of this utility model all enable full key rollover of the magnetic induction keyboard, which is determined by its inherent properties.

[0023] 3. The single-sided FPC made of the magnetic color induction chip, magnetic color induction chip or magnetic color induction chip is easier to assemble, maintain and service if it is pasted on the lower surface of the overall fixing plate.

[0024] 4. This utility model's magnetic induction scissor-switch key with built-in magnetic induction element is well compatible with existing scissor-switch layouts, while transforming the keyboard keys into a magnetic induction method with changing polarity, greatly extending the key lifespan. The modular structure of this utility model's magnetic induction scissor-switch key is flexible and versatile, resulting in keyboards that are not only long-lasting but also available in various forms.

[0025] 5. When the keycap is pressed, the magnet passes through the horizontal induction critical surface of the unipolar magnetic induction chip. The induction polarity of the magnetic element relative to the magnetic induction chip is reversed, and the high level output by the magnetic induction chip becomes a low level. The corresponding digital logic changes from 1 to 0. It has natural switching properties and is a digital magnetic induction method with good anti-interference.

[0026] 6. The magnetic induction integrated circuit chip of this invention has a built-in RGB color function, which makes the lighting indication effect dreamlike, and the logical communication between the button and the lighting indication will be more efficient and simple.

[0027] 7. The present invention uses magnetic color-changing magnetic induction chip, magnetic color-changing magnetic induction chip and magnetic color-carrying magnetic induction chip respectively to make a single-sided FPC scissor-angle keyboard with very few wires between components, which can be naturally made into a split keyboard or a folding keyboard.

[0043] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.

[0044] Example 1

[0045] like Figure 1 A scissor-switch magnetic keypad with a silicone cap 5 as the key reset element includes a scissor-switch structure 1, an overall fixing plate 2, keycaps 3, silicone caps 5, and a single-sided FPC 7 made of several magnetic induction integrated circuit chips 6. The bottom of the scissor-switch structure 1 is fixed to the overall fixing plate 2, and the top is fixed to the keycaps 3. A magnetic element 4 is fixedly installed below the keycaps 3. The silicone cap 5 is located in the hollow part of the scissor-switch structure 1 and directly below the magnetic element 4, used for resetting the scissor-switch structure 1 and the keys. The single-sided FPC 7 is tightly attached to the lower surface of the overall fixing plate 2, and the bottom of the silicone cap 5 is supported on the upper surface of the overall fixing plate 2.

[0046] Pressing keycap 3 simultaneously causes magnetic component 4 to press down, and scissor-switch mechanism 1 and silicone cap 5 are also compressed downwards. As keycap 3 is pressed down, magnetic component 4 passes through the magnetic induction surface of magnetic induction integrated circuit chip 6, and the polarity of magnetic induction integrated circuit chip 6 is reversed. Releasing keycap 3 simultaneously causes magnetic component 4 to rise, and scissor-switch mechanism 1 and silicone cap 5 are reset.

[0047] Magnetic components are used as switches in magnetic induction integrated circuit chips, i.e., the outputs of digital logic 1 or 0.

[0048] like Figure 5 Only one magnetic induction integrated circuit chip 6 needs to be set on a single-sided FPC7. Multiple magnetic induction integrated circuit chips 6 can be cascaded and connected to an external MCU through 4 lines.

[0049] like Figure 2 , 5The magnetic induction integrated circuit chip 6 on a single-sided FPC7 uses a MagSeriLux chip. The MagSeriLux chip has built-in RGB LEDs, and its signal input and output lines are cascaded end to end, using a serial communication method. The MagSeriLux chip integrates a magnetic induction circuit and a RGB circuit. Several magnetic induction integrated circuit chips 6 are cascaded. Each magnetic induction integrated circuit chip 6 includes a power pin, a ground pin, a data information input pin, and a data information output pin. The data information output pin of the magnetic induction integrated circuit chip 6 is connected to the data information input pin of the next adjacent magnetic induction integrated circuit chip 6, and the data information input pin of the magnetic induction integrated circuit chip 6 is connected to the data information output pin of the previous adjacent magnetic induction integrated circuit chip 6. The connection between the data information input pins and data information output pins of several magnetic induction integrated circuit chips 6 forms a data line. The power network VCC, ground network GND, data information input network DI(1), and data information output network DO(n) on the FPC are connected to an external MCU to process data information. The FPC has four connection pins.

[0050] Several silicone caps 5 are attached to the overall fixing plate 2.

[0051] like Figure 12 In the initial state, the bottom of the magnetic element 4 below the keycap 3 is above the horizontal magnetic induction surface of the magnetic induction chip, meaning the N pole of the magnetic element 4 is close to the S pole of the magnetic induction chip (assuming different polarities are defined as high level output and the same polarity as low level output). Therefore, the magnetic induction chip outputs a high level at this time. Figure 13 As the key is pressed down to the bottom, the bottom of the magnetic element 4 below the keycap 3 is below the horizontal magnetic induction surface of the magnetic induction chip, and the top of the magnetic element 4 is above the horizontal magnetic induction surface. The N pole of the magnetic element 4 is close to the N pole of the magnetic induction chip, and the S pole of the magnetic element 4 is close to the S pole of the magnetic induction chip. According to the definition (assuming that different induction polarities are defined as high level and the same induction polarity is defined as low level), the magnetic induction integrated circuit chip 6 (magnetic induction chip) outputs a low level at this time. This method of changing the induction polarity of the magnetic induction integrated circuit chip 6 (magnetic induction chip) by the displacement of the magnetic element 4, thereby making the magnetic induction chip output high and low levels, has better reliability and stronger stability.

[0053] This embodiment is the same as Embodiment 1 except for the following content:

[0054] like Figure 3 , 6The magnetic induction integrated circuit chip 6 on each single-sided FPC7 uses a MagSyncLux chip. The MagSyncLux chip has built-in RGB LEDs, and its power lines, ground lines, and signal lines are connected in parallel, using an addressable serial communication method. The MagSyncLux chip integrates magnetic induction circuitry and RGB color circuitry. Each magnetic induction integrated circuit chip 6 includes a power pin, a ground pin, and a data pin. The power pins of several magnetic induction integrated circuit chips 6 are connected in parallel to share a common power network VCC, the ground pins are connected in parallel to share a common ground network GND, and the data pins are connected in parallel to share a common data line network DIO. Data information is transmitted on the data line network DIO. The power network VCC, the ground network GND, and the data input / output network DIO on the FPC are connected to an external MCU for data processing.

[0056] This embodiment is the same as Embodiment 1 except for the following content:

[0057] like Figure 4 , 7 The magnetic induction integrated circuit chip 6 on a single-sided FPC7 uses a MagVoltLux chip, which integrates RGB LEDs and uses power line carrier communication for addressable serial communication over the power line. The MagVoltLux chip integrates magnetic induction circuitry and RGB lighting circuitry. Several MagVoltLux chips 6 are connected in parallel to the MCU on the PCB. Each MagVoltLux chip 6 includes a power pin and a ground pin. The power pins of several MagVoltLux chips 6 are connected in parallel to share a common power network VCC, and the ground pins are connected in parallel to share a common ground network GND. Data is modulated onto the power network VCC for transmission. The power network VCC (DIO) and the ground network GND, these two networks on the FPC, are connected to an external MCU for data processing.

[0058] Example 4

[0059] This embodiment is the same as Embodiment 1 except for the following content:

[0060] A single-sided FPC7 sheet is tightly attached to the upper surface of the overall fixing plate 2, and the bottom of the silicone cap 5 is supported on the upper surface of the overall fixing plate 2.

[0061] Example 5

[0062] like Figure 8A scissor-switch magnetic keypad with a silicone cap 5 as the key reset element includes a scissor-switch structure 1, an overall fixing plate 2, keycaps 3, a silicone cap 5 with a through hole 8 in the middle, and a single-sided FPC 7 made of several magnetic induction integrated circuit chips 6. The bottom of the scissor-switch structure 1 is fixed to the overall fixing plate 2, and the top is fixed to the keycap 3. A magnetic element 4 is fixedly installed below the keycap 3. The silicone cap 5 is located in the hollow part of the scissor-switch structure 1, and the magnetic element 4 passes through the through hole 8 of the silicone cap 5 when not pressed. When the keycap 3 is assembled, a portion of the magnetic element 4 passes through the through hole 8 of the silicone cap 5; that is, when the keycap 3 is in a stationary state / not pressed state, the magnetic element 4 is in a state of passing through the through hole 8 of the silicone cap 5. When the keycap 3 is pressed down, the magnetic element 4 passes through the magnetic induction surface of the magnetic induction integrated circuit chip 6; the silicone cap 5 is used for the reset of the scissor-switch structure 1 and the key; a single-sided FPC 7 is tightly attached to the lower surface of the overall fixing plate 2, and the bottom of the silicone cap 5 is supported on the upper surface of the overall fixing plate 2;

[0063] Pressing keycap 3 simultaneously causes magnetic component 4 to press down, and scissor-switch mechanism 1 and silicone cap 5 are also compressed downwards. As keycap 3 is pressed down, magnetic component 4 passes through the magnetic induction surface of magnetic induction integrated circuit chip 6, and the polarity of magnetic induction integrated circuit chip 6 is reversed. Releasing keycap 3 simultaneously causes magnetic component 4 to rise, and scissor-switch mechanism 1 and silicone cap 5 are reset.

[0064] The magnetic induction integrated circuit chip 6 can be a magnetic color chip, a magnetic color collection chip, or a magnetic color carrier chip.

[0065] Example 6

[0066] This embodiment is the same as embodiment 5 except for the following content:

[0067] A single-sided FPC7 sheet is tightly attached to the upper surface of the overall fixing plate 2, and the bottom of the silicone cap 5 is supported on the upper surface of the overall fixing plate 2.

[0068] In embodiments 1 to 6, the scissor-switch magnetic axis keyboard using silicone caps 5 as key reset elements further includes a single sheet of film 9, with several silicone caps 5 distributed on the single sheet of film 9. The film 9 has a first clearance hole 10, which is used to avoid the scissor-switch fixing slot on the overall fixing plate 2. Placing all the silicone caps 5 on a single sheet of film 9 makes assembly more convenient. Figure 9 The silicone cap 5 does not have a through hole 8 in the middle, corresponding to embodiments 1 to 4. Figure 10 , 11 The silicone cap 5 has a through hole 8 in the middle, corresponding to embodiments 5 and 6.

[0069] In embodiment 4 or 6, when a single-sided FPC7 is tightly attached to the upper surface of the overall fixing plate 2, the single-sided FPC7 is provided with a second clearance hole; the lower surface of the entire film 9 is provided with a groove to avoid the magnetic induction integrated circuit chip 6.

[0070] In embodiments 4 or 6, the lower surface of the entire thin film 9 may not have a groove for accommodating / avoiding the magnetic induction integrated circuit chip 6, because the entire thin film 9 is relatively soft, and the overall structure after assembly can still remain flat.

[0071] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
