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 that uses a spring 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 spring as the key reset element.

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

The bottom of the scissor-switch mechanism is fixed to the overall fixing plate, and the top is fixed to the keycaps. Spring-loaded elements are located in the hollow portion of the scissor-switch mechanism for resetting both the mechanism and the keys. A magnetic element is fixed below the keycaps. The single-sided FPC is tightly attached to the lower surface of the overall fixing plate. A second clearance hole is provided on the spring-loaded elements directly below the magnetic element and on the overall fixing plate. This second clearance hole allows the magnetic element to move up and down and to avoid the magnetic induction integrated circuit chips on the single-sided FPC.

[0006] When the keycap is pressed, the spring is simultaneously pressed down, and the magnetic element passes through the magnetic induction surface of the magnetic induction integrated circuit chip as the keycap is pressed down, causing the induction polarity of the magnetic induction integrated circuit chip to change.

The bottom of the scissor-switch mechanism is fixed to the overall fixing plate, and the top is fixed to the keycaps. A spring-loaded element is located in the hollow part of the scissor-switch mechanism for resetting the mechanism and the keys. A magnetic element is located below the spring-loaded element. The single-sided FPC is tightly attached to the lower surface of the overall fixing plate. The overall fixing plate directly below the magnetic element has a second clearance hole, which allows the magnetic element to move up and down and to avoid the magnetic induction integrated circuit chips on the single-sided FPC.

[0008] Pressing the keycap simultaneously causes the spring to press down, and the magnetic element passes through the magnetic induction surface of the magnetic induction integrated circuit chip as the spring is pressed down, causing the induction polarity of the magnetic induction integrated circuit chip to change.

[0010] When the keycap is pressed, the spring is simultaneously pressed down, and the magnetic element passes through the magnetic induction surface of the magnetic induction integrated circuit chip as the keycap is pressed down, causing the induction polarity of the magnetic induction integrated circuit chip to change.

[0011] A scissor-switch magnetic keypad with a spring-loaded key reset element includes a scissor-switch mechanism, an overall fixing plate, keycaps, spring-loaded elements, 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. The spring-loaded elements are located in the hollow part of the scissor-switch mechanism and are used for resetting the scissor-switch mechanism and the keys. A magnetic element is located below the spring-loaded elements. The single-sided FPC is tightly attached to the upper surface of the overall fixing plate. A second clearance hole is provided on the single-sided FPC directly below the magnetic element, allowing the magnetic element to move up and down.

[0012] Pressing the keycap simultaneously causes the spring to press down, and the magnetic element passes through the magnetic induction surface of the magnetic induction integrated circuit chip as the spring is pressed down, causing the induction polarity of the magnetic induction integrated circuit chip to change.

[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 spring clips are attached or snapped onto the overall fixing plate.

[0018] The scissor-switch magnetic axis keyboard with springs as key reset elements also includes a whole film, with several springs 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 spring sheet 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, 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 with not only long lifespans but also diverse 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.

[0044] 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.

[0045] Example 1

[0046] like Figure 1 , 12 A scissor-switch magnetic keypad with a spring 5 as the key reset element includes a scissor-switch structure 1, an overall fixing plate 2, keycaps 3, spring 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. The spring 5 is located in the hollow part of the scissor-switch structure 1 and is 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. A magnetic element 4 is located below the spring 5, and the overall fixing plate 2 directly below the magnetic element 4 has a second clearance hole 8 for the up-and-down movement of the magnetic element 4. Figure 5 There is no need to set a second clearance hole and a first clearance hole on a single-sided FPC. Only a magnetic induction integrated circuit chip is needed. Multiple magnetic induction integrated circuit chips are cascaded and connected to an external MCU through 4 lines.

[0047] Pressing keycap 3 simultaneously causes spring 5 to press down, and magnetic element 4 passes through the magnetic induction surface of magnetic induction integrated circuit chip 6 as spring 5 is pressed down, causing the polarity of magnetic induction integrated circuit chip 6 to change.

[0048] Magnetic element 4 is used as a switch for the magnetic induction integrated circuit chip 6, i.e., the output of digital logic 1 or 0.

[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] like Figure 11 The scissor-switch magnetic keypad also includes a single sheet of film 9, with spring pieces 5 distributed on the single sheet of film 9, and a second clearance hole 8 for the magnetic element 4 to move up and down is opened at the corresponding position of the single sheet of film 9 directly below the magnetic element 4.

[0051] Or, such as Figure 14 Several spring clips 5 are directly distributed (e.g., snapped) on the overall fixing plate 2.

[0052] When the single-sided FPC 7 is tightly attached to the lower surface of the overall fixing plate 2, the corresponding position of the overall fixing plate 2 above the magnetic induction integrated circuit chip 6 is set as an empty slot. In this way, the FPC does not occupy extra space when it is attached to the bottom of the fixing plate, and the overall height of the keyboard becomes thinner.

[0053] First of all Figure 11 The entire film 9 with the spring sheet 5 shown is placed... Figure 12 As shown, fix the entire assembly onto plate 2, then install keycaps 3 on each key, and then... Figure 5 The single-sided FPC7 made of the magnetic color chip shown is adhered to... Figure 12 The lower surface of the overall fixing plate 2 forms the main frame for the scissor-leg mechanism of the spring piece 5 and the magnetic color chip FPC. During assembly, the thin film 9 is provided with first clearance holes 10 at the points of conflict. The first clearance holes 10 are used to avoid the scissor-leg fixing slots on the overall fixing plate 2.

[0054] like Figure 12The overall fixing plate 2 is provided with a second clearance hole 8, which is used to prevent the magnetic element 4 on the spring piece 5 from passing through the second clearance hole 8 when pressed, and at the same time to avoid the magnetic induction chip on the FPC board, thus saving more space.

[0055] like Figure 9 In the initial state, the bottom of the magnetic element 4 inside the spring 5 is above the horizontal magnetic induction surface of the magnetic induction chip, that is, the N pole of the magnetic element 4 is close to the S pole of the magnetic induction chip (assuming that 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 10 As the button is pressed down to the bottom, the bottom of the magnetic element 4 inside the spring 5 is below the horizontal magnetic induction surface of the Magnetic Color 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 Color Induction Chip, and the S pole of the magnetic element 4 is close to the S pole of the Magnetic Color 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 output of the Magnetic Color Induction Integrated Circuit Chip 6 (Magnetic Color Chip) is low level at this time. This method of changing the induction polarity of the Magnetic Color Induction Integrated Circuit Chip 6 (Magnetic Color Chip) by the displacement of the magnetic element 4, thereby making the Magnetic Color Chip output high and low levels, has better reliability and stronger stability.

[0056] Example 2

[0057] This embodiment is the same as Embodiment 1 except for the following content:

[0058] like Figure 3 , 6 13. The magnetic induction integrated circuit chip 6 on the 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 a magnetic induction circuit and a RGB color circuit. 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 power network VCC, the ground pins are connected in parallel to share a ground network GND, and the data pins are connected in parallel to share a 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 information input / output network DIO on the FPC are connected to an external MCU to process data information.

[0059] Here's an explanation of the working principle of the MagSyncLux chip: The MagSyncLux chip has a built-in RGB LED, and its power, ground, and signal lines can be connected in parallel. It uses an addressable serial communication method for magnetic induction sensors. Each magnetic induction chip includes a power pin, a ground pin, and a data pin. The power pins of several magnetic induction integrated circuit chips are connected in parallel to share the power network VCC, the ground pins are connected in parallel to share the ground network GND, and the data pins are connected in parallel to share the data line network DIO. Data information is transmitted on the data line network DIO.

[0060] Each magnetic color chip device is sorted and encoded after being installed in the FPC, so that its address code corresponds to its actual sequence code on the FPC. Figure 3 In this configuration, the first MagSyncLux chip has the first serial number and the corresponding address code is 1; the second MagSyncLux chip has the second serial number and the corresponding address code is 2; the third MagSyncLux chip has the third serial number and the corresponding address code is 3; and so on, up to the nth MagSyncLux chip, which has the nth serial number and the corresponding address code is n. Data operations on the address codes are operations on the corresponding MagSyncLux chips. This data includes magnetic button information, magnetic parameter settings (magnetic induction polarity settings, magnet BOP, BRP settings), and RGB color grayscale information. The FPC connection has 3 pins.

[0061] like Figure 6 , 13 There is no need to set a second clearance hole and a first clearance hole on a single-sided FPC. Only a magnetic induction integrated circuit chip is needed. Multiple magnetic induction integrated circuit chips are connected in parallel and connected to an external MCU through 3 lines.

[0062] Example 3

[0063] This embodiment is the same as Embodiment 1 except for the following content:

[0064] like Figure 4 , 7The 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 the power network VCC, and the ground pins are connected in parallel to share the 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. The FPC has only two connection pins, making it simpler.

[0065] like Figure 7 There is no need to set a second clearance hole and a first clearance hole on a single-sided FPC. Only a magnetic induction integrated circuit chip is needed. Multiple magnetic induction integrated circuit chips are connected in parallel and connected to an external MCU through two lines.

[0066] Example 4

[0067] This embodiment is the same as Embodiment 1 except for the following content:

[0068] like Figure 8 A magnetic element 4 is fixedly installed below the keycap 3; the spring 5 directly below the magnetic element 4 and the overall fixing plate 2 are provided with a second clearance hole 8, which is used for the magnetic element 4 to move up and down and to avoid the magnetic induction integrated circuit chip 6 on the single-sided FPC 7.

[0069] The scissor-switch magnetic key also includes a single sheet of film 9, with spring contacts 5 distributed on the single sheet of film 9, and a second clearance hole 8 is opened at the corresponding position of the single sheet of film 9 directly below the magnetic element 4 to allow the magnetic element 4 to move up and down.

[0070] Alternatively, several spring clips 5 can be directly distributed (e.g., snapped together) on the overall fixing plate 2.

[0071] At this time, there is no magnetic element 4 below the spring 5; the magnetic element 4 is located below the keycap 3.

[0072] Example 5

[0073] This embodiment is the same as Embodiment 1 except for the following content:

[0074] A single-sided FPC sheet is tightly attached to the upper surface of the overall fixing plate; the single-sided FPC sheet directly below the magnetic element is provided with a second clearance hole, which is used for the magnetic element to move up and down.

[0075] Example 6

[0076] This embodiment is the same as Embodiment 1 except for the following content:

[0077] A magnetic element is fixedly installed below the keycap; the spring, single-sided FPC, and overall fixing plate directly below the magnetic element 4 are provided with a second clearance hole.

[0078] In embodiments 1 to 6, the scissor-switch magnetic axis keyboard with spring contacts as key reset elements further includes a single sheet of film, with several spring contacts distributed on the film. A first clearance hole is provided on the film to allow clearance from the scissor-switch fixing slots on the overall fixing plate. Placing all spring contacts on a single sheet of film makes assembly more convenient.

[0079] In embodiment 5 or 6, when a single-sided FPC is tightly attached to the upper surface of the overall fixing plate, a groove is provided on the lower surface of the entire film to avoid the magnetic induction integrated circuit chip.

[0080] In embodiment 5 or 6, the lower surface of the entire thin film may not have a groove for accommodating / avoiding the magnetic induction integrated circuit chip, because the entire thin film is relatively soft and the overall structure after assembly can still remain flat.

[0081] 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.
