According to the magnetic axis keyboard, the magnetic sensor corresponding to each magnetic axis key on the magnetic axis keyboard does not need to be continuously kept in a high-power-consumption working state, but the magnetic sensor corresponding to the magnetic axis key is activated only when one magnetic axis key is pressed down, so that the power consumption of the magnetic axis keyboard is greatly reduced.

Description

Technical Field

[0001] The utility model relates to a method for reducing energy consumption of electronic equipment. By controlling the state of a magnetic sensor in the electronic equipment, the power consumption of the electronic equipment is significantly reduced. The utility model is particularly suitable for related equipment using magnetic axis keys and magnetic axis keyboards. Background Art

[0002] With the continuous advancement of electronic device control technology, in addition to traditional mechanical switches, technologies utilizing optical and magnetic induction control have gradually been adopted. For example, in the field of mechanical keyboards, starting in the 1980s, product types have emerged, including mechanical switch keyboards (around 1984), optical switch keyboards (around 2014), and magnetic switch keyboards (around 2019). Magnetic switch keyboards are favored by users for their faster response speed and more stable input quality. Each key in a magnetic switch keyboard has a magnet and a corresponding magnetic sensor. When the key is not pressed, the magnet remains at a certain distance from the magnetic sensor. When the key is pressed, the magnet moves closer to the magnetic sensor as the key is depressed. The magnetic sensor senses the change in the magnetic field and generates a corresponding sensing output. While magnetic switch keyboards offer many advantages, the fact that each key requires a corresponding magnetic sensor, which must be constantly active, results in high energy consumption and high heat generation. Consequently, magnetic switch keyboards require larger batteries. This additional battery not only increases cost but also takes up more space on the keyboard, making heat dissipation more difficult. Even on non-portable devices with sufficient power, magnetic induction sensitivity can decrease over time, leading to instability in keyboard input and the entire electronic device. Battery-powered portable devices also face issues such as low space utilization and excessive energy consumption, making magnetic switch keyboards unsuitable for portable devices such as laptops. Utility Model Content

[0003] On one hand, the present invention provides a method for controlling the operating state of a magnetic sensor, which is applied to a magnetic axis keyboard. The magnetic axis keyboard includes a magnetic axis key and a magnetic sensor corresponding to the magnetic axis key. The method is characterized in that when the key is not pressed, the magnetic sensor is in a non-operating state, and when the key is pressed, the magnetic sensor switches to an operating state. The magnetic sensor of the present invention includes various Hall elements, magnetoresistive elements (including but not limited to AMR, GMR, TMR), etc., which are referred to in the industry as any element that can cooperate with a magnetic part to form a magnetic induction effect (or Hall effect). The non-operating state is a power-off state or a dormant state in which the power consumption is far less than the normal operating power consumption. At this time, the power consumption of the magnetic sensor itself is 0 or almost 0.

[0004] Furthermore, when the button is not pressed, the power supply circuit of the magnetic sensor is in an off-circuit state, and when the magnetic axis button is pressed, the power supply circuit of the magnetic sensor is switched to a on-circuit state. The power supply circuit mentioned in the present invention is a circuit in a broad sense. How to implement a power supply circuit for a magnetic sensor is also common knowledge in the field. As long as it is a circuit that can be used to power a magnetic sensor, it can be an integrated circuit, an electronic component combination, or a combination of multiple types of circuits. The control of the power supply circuit can be mechanical physical control or control through programs, software, etc. Unless otherwise specified in the specific solution, the specific implementation form of the circuit is not limited to hardware, control logic, etc.

[0005] Furthermore, when the button is not pressed, the power supply circuit of the magnetic sensor inputs an electrical signal so that the magnetic sensor cannot be turned on normally. When the magnetic axis button is pressed, the power supply circuit of the magnetic sensor inputs another electrical signal so that the magnetic sensor switches to the working state.

[0006] Furthermore, the magnetic axis button is provided with a switch for controlling the working state of the magnetic sensor. When the magnetic axis button is pressed, the on / off state of the switch is switched, so that the magnetic sensor is switched to the working state.

[0007] Furthermore, the switch is a normally open switch. When the button is not pressed, the switch remains open. When the magnetic axis button is pressed, the switch closes, causing the magnetic sensor to switch to a working state.

[0008] Furthermore, the switch is a normally closed switch. When the button is not pressed, the switch remains closed. When the magnetic axis button is pressed, the switch is opened, so that the magnetic sensor switches to a working state.

[0009] Furthermore, when the button is pressed beyond a certain distance, the magnetic sensor switches to an active state. Since users are accustomed to triggering input signals at a certain pressing position when using buttons, to adapt to users' actual usage habits and prevent accidental activation of the magnetic sensor due to accidental touches, the button is configured to switch the magnetic sensor to an active state when pressed beyond a certain distance of 0.03mm. This ensures the user's actual usage feel and increases the button's sensitivity.

[0010] Furthermore, when the sensor switches to an active state, the keyboard provides a visual or audible prompt. To facilitate player feedback, increase playability, and facilitate maintenance, the keyboard is equipped with a built-in indicator light and / or speaker to provide visual and / or audible prompts when the magnetic sensor switches to an active state.

The present invention does not limit the specific structure of the magnetic axis key. As long as the magnetic axis key can realize input using the magnetic induction principle, the present invention can be used to improve it, which can achieve energy consumption reduction and structural improvement. Since the mass production of products in 2019, the realization of the magnetic axis key itself has been roughly finalized, and the specific structural realization of the magnetic axis key is already common sense. Unless otherwise specified in the present invention, it is not limited to a specific implementation method. Moreover, even if it is an improvement on the magnetic axis key itself, it does not affect the application of the logic of controlling the working state of the magnetic sensor in the present invention.

[0012] Furthermore, when the magnetic axis button is not pressed, the switch is in an open or closed state, at which time the magnetic sensor is in a non-working state.

The switch is located within the accommodation space. The magnetic sensor is soldered to the PCB. The top cover snaps into place with the base. The elastic member is a spring. The upper portion of the shaft core is a cross-shaped shaft (also known as a cross bone in the industry). The magnetic member is a magnet. The elastic member is mounted outside the guide ring and guide post. The magnetic sensor can be located on the same side of the PCB as the magnetic axis button or on the opposite side.

DETAILED DESCRIPTION

[0065] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0066] On one hand, the utility model provides a method for controlling the operating state of a magnetic sensor, which is applied to a magnetic axis keyboard. The magnetic axis keyboard includes a magnetic axis key and a magnetic sensor corresponding to the magnetic axis key: when the key is not pressed, the magnetic sensor is in a non-operating state; when the key is pressed, the magnetic sensor switches to an operating state. When the magnetic axis key is not pressed, the magnetic sensor is in a non-operating state, which is a power-off state or a dormant state in which power consumption is far less than that of normal operation. In this state, the power consumption of the magnetic sensor itself is zero or almost zero. When the magnetic axis key is pressed, the magnetic sensor can switch from the non-operating state to the operating state, and the power consumption of the magnetic sensor is normal to ensure the normal implementation of magnetic induction. The magnetic sensor corresponding to each magnetic axis button on the magnetic axis keyboard does not need to be in a high-power consumption working state in real time. Instead, the magnetic sensor corresponding to the magnetic axis button is activated only when one of the magnetic axis buttons is pressed, which greatly reduces the power consumption of the magnetic axis keyboard. At the same time, the heat generated by the magnetic axis keyboard is also greatly reduced, and the magnetic axis button will not experience high-temperature sensing failure, affecting the input stability. At the same time, for portable magnetic axis keyboards or electronic devices that rely on batteries, it not only solves the heating problem caused by large-capacity batteries, but also increases the usage time of a single charge or a single battery replacement, greatly improving the usage scenarios of magnetic axis buttons or magnetic axis keyboards, and can be widely adapted to portable electronic devices.

[0067] Furthermore, in one embodiment, when the button is not pressed, the power supply circuit of the magnetic sensor is in an off-circuit state. When the magnetic axis button is pressed, the power supply circuit of the magnetic sensor is switched on. In the off-circuit state, the magnetic sensor is not connected to the power supply circuit, and thus does not consume power or generate heat.

[0068] Furthermore, in one embodiment, when the button is not pressed, the power supply circuit of the magnetic sensor inputs an electrical signal that prevents the magnetic sensor from turning on normally. When the magnetic axis button is pressed, the power supply circuit of the magnetic sensor inputs another electrical signal, causing the magnetic sensor to switch to an operating state. The inability to turn on normally indicates that the magnetic sensor is disconnected or in a low-power sleep state. In this embodiment, the power supply of the magnetic sensor can be controlled by a chip. When the button is not pressed, the chip outputs a low level, and the magnetic sensor does not work. When the magnetic axis button is pressed, the chip outputs a high level, and the magnetic sensor works.

[0069] Furthermore, in one embodiment, the magnetic axis button is provided with a switch for controlling the working state of the magnetic sensor. When the magnetic axis button is pressed, the on / off state of the switch is switched, so that the magnetic sensor switches to the working state. A switch is provided in the magnetic axis button in linkage with the magnetic axis button, and the switch controls the working state of the magnetic sensor. Figure 1 and Figure 2 As shown in the figure, SW1 and SW2 represent switches, which can be normally open switches, that is, the switches are disconnected in the initial state and closed when the magnetic axis button is pressed. Figure 7 and Figure 8 As shown in the figure, SW3 and SW4 represent switches, which can also be normally closed switches. Initially, the switches are closed and open when the magnetic axis button is pressed. Whether they are normally open or closed, when the magnetic axis button is pressed, the switch switches between open and closed states, and the magnetic sensor enters the operating state. When the magnetic axis button is reset, the switch switches between open and closed states again, and the magnetic sensor returns to the non-operating state.

[0070] Furthermore, in one embodiment, the switch is a normally open switch, such as Figure 1 and Figure 2 ,for Figure 1 or Figure 2 With a slight modification to the existing circuit, the normally open switch can be connected to either the power supply GND or VDD. When the button is not pressed, the switch remains open. When the magnetic axis button is pressed, the switch closes, switching the magnetic sensor to the working state. Figure 1 SW1 represents a switch, U1 represents a magnetic sensor 10, and the switch is a normally open switch. When the magnetic axis button is not pressed, the switch remains open, and when the magnetic axis button is pressed, the switch is closed. Figure 2 In the figure, SW2 represents a switch, U3 represents the magnetic sensor 10, and U2 represents the control chip. The switch is a normally open switch. When the magnetic axis button is not pressed, the switch remains open. When the magnetic axis button is pressed, the switch closes. U2 can be an MCU, or other chips or other electronic components that can perform the corresponding functions. For magnetic sensors with an EN terminal (enable terminal), the normally open switch described above can directly input a switch closing or opening signal to the EN terminal of the magnetic sensor. In other words, when the switch is open, the magnetic sensor is in a low-power standby state. When the switch is closed, the magnetic sensor exits the standby state and begins operation.

[0071] Furthermore, in one embodiment, the switch is a normally closed switch, such as Figure 7 and Figure 8 ,for Figure 7 or Figure 8, the existing circuit is slightly changed, the normally closed switch is connected to the power supply GND and VDD, when the key is not pressed, the switch remains closed, when the magnetic shaft key is pressed, the switch is opened, and the magnetic sensor is switched to the working state. Figure 7 In the circuit, U4 is a magnetic sensor, R1 is a resistor, and SW3 is a switch. Figure 7 In the circuit, U6 is a magnetic sensor, U5 is a control chip, and SW4 is a switch. Figure 8 In the circuit, U6 is a magnetic sensor, U5 is a control chip, and SW4 is a switch.

[0072] Further, in an embodiment, when a user uses a key, the user is accustomed to triggering an input signal at a certain pressing position, in order to adapt to the actual use habit of the user and prevent the magnetic sensor from being mistakenly opened due to mistaken touch, in the embodiment, when the key is set to be pressed by more than 0.03 mm, the magnetic sensor is switched to the working state.

[0073] Further, in an embodiment, when the magnetic sensor is switched to the working state, the keyboard gives a visual prompt or an audible prompt.

[0074] The utility model discloses a magnetic shaft keyboard, including: PCB8 and magnetic shaft key, magnetic shaft key with PCB8 is connected, install with the magnetic sensor 10 corresponding with the key on PCB8, its characterized in that: magnetic shaft key includes the switch of control magnetic sensor 10 working condition.

[0075] In the magnetic axis keyboard of this embodiment, when the magnetic axis button is not pressed, the switch is in an open or closed state, at which time the magnetic sensor 10 is in a non-working state. When the magnetic axis button is pressed, the switch is switched between open and closed states, at which time the magnetic sensor 10 is switched to a working state.

[0076] In a further embodiment, the magnetic axis key can include a base 5, an upper cover 1, an elastic member 4, and a shaft core 2. A magnetic sensor 10 is mounted on the PCB 8. The bottom end of the base 5 is connected to the PCB 8. A guide ring 6 is provided on the inner surface of the base 5. The upper cover 1 and the base 5 are connected to form an accommodating space. The elastic member 4 is disposed in the accommodating space. A guide post is provided at the lower end of the shaft core 2 to cooperate with the guide ring 6. The lower portion of the shaft core 2 abuts the elastic member 4. The upper portion of the shaft core 2 can slide out of the upper cover 1. The shaft core 2 is connected to a magnetic member 3. The accommodating space also contains the switch for controlling the working state of the magnetic sensor 10. The magnetic sensor 10 is welded to the PCB 8. The upper cover 1 is buckled with the base 5. The elastic member 4 is a spring. The upper portion of the shaft core 2 is a cross shaft that can be used to connect a keycap or other components. The magnetic member 3 is a magnet. The elastic member 4 is sleeved on the outside of the guide ring 6 and the guide post.

[0077] Furthermore, in one embodiment, Figure 3 and Figure 4 As shown, in the magnetic axis keyboard provided in this embodiment, the switch is a normally open switch. When the magnetic axis key is not pressed, the switch remains open. When the magnetic axis key is pressed, the switch is closed. The switch includes a first insulating block 11 provided on the shaft core 2, and two first conductive plates 7 provided on the base 5. The first conductive plates 7 pass through the base 5 and are electrically connected to the PCB 8 via an elastic card 9. When the shaft core 2 is not pressed, the first insulating block 11 is located between the two first conductive plates 7. At this time, the switch is in an open state. When the shaft core 2 moves downward, the first insulating block 11 moves downward with the shaft core 2, and the two first conductive plates 7 abut against each other. At this time, the switch is in a closed state. At least one of the first conductive plates 7 is an elastic metal plate. The elastic card 9 is also a prior art, and its specific structure, installation, and connection method are not repeated here.

[0078] Furthermore, in one embodiment, Figure 5 、 Figure 6As shown, in the magnetic axis keyboard provided in this embodiment, the switch includes two second conductive sheets arranged on the base 5, and the second conductive sheets pass through the base 5 and are electrically connected to the PCB8. In this embodiment, the second conductive sheets are also connected to the PCB8 through the elastic card 9. Figure 3 and Figure 4 The connection method shown is similar, one of the second conductive pieces is a fixed piece 12, and the other second conductive piece is a spring piece 13. When the shaft core 2 is not pressed, the spring piece 13 is not in contact with the fixed piece 12, and the switch is in an open state. When the shaft core 2 moves downward, the spring piece 13 abuts against the fixed piece 12, and the switch is in a closed state. Figure 5 and Figure 6 As shown, in this embodiment, when the shaft core 2 moves downward, it pushes the spring piece 13 to move partially and abut against the fixed piece 12. Of course, the abutment can also be achieved by blocking the spring piece 13 from moving toward the fixed piece 12 before the shaft core 2 moves downward, and no longer blocking the spring piece 13 from moving toward the fixed piece 12 after the shaft core 2 moves downward, or other connection forms for achieving abutment are not specifically limited in the present utility model.

[0079] Furthermore, in one embodiment, Figure 1 As shown, in the magnetic axis keyboard provided in this embodiment, the switch SW1 is a normally open switch and is connected in series to the power supply circuit of the magnetic sensor 10. When the axis core 2 is not pressed, the power supply circuit of the magnetic sensor 10 is in an open state. When the magnetic axis key is pressed, the power supply circuit of the magnetic sensor 10 switches to an open state. In the open state, the magnetic sensor 10 is not connected to the power supply circuit, and thus does not consume power and generate heat.

[0080] Furthermore, in one embodiment, Figure 2 As shown, in the magnetic axis keyboard provided in this embodiment, the switch SW2 is a normally open switch. The switch SW2 is electrically connected to one end of a control chip U2. When the switch SW2 is closed, the end of the control chip U2 electrically connected to the magnetic sensor 10 outputs a signal, switching the magnetic sensor 10 into an operating state. Alternatively, the signal output by U2 can be used to control the on / off of the magnetic sensor's operating voltage via a transistor or field-effect transistor.

[0081] Furthermore, in one embodiment, in the magnetic axis keyboard provided in this embodiment, the switch is a normally closed switch. When the axis core 2 is not pressed, the switch remains closed, and when the axis core 2 is pressed, the switch is opened.

[0082] Furthermore, in one embodiment, Figure 9 、 Figure 10As shown, the switch includes a second insulating block 14 arranged on the shaft core 2, and two third conductive plates 15 arranged in the base 5. The third conductive plates 15 pass through the base 5 and are electrically connected to the PCB 8. When the shaft core 2 is not pressed, the second insulating block 14 is located above the two third conductive plates 15, and the two third conductive plates 15 are in contact. At this time, the switch is in a closed state. When the shaft core 2 moves downward, the second insulating block 14 moves downward with the shaft core 2, separating the two third conductive plates 15. At this time, the switch is in an open state. In some embodiments, the second insulating block 14 can also be initially set between the two third conductive plates 15. When the insulating block 14 moves downward, the third conductive plates 15 can also be separated to realize the on-off switching of the switch. At least one of the third conductive plates 15 is an elastic metal plate.

[0083] In one embodiment, as Figure 11 and Figure 12 As shown, the switch includes two fixed conductive plates 17 arranged relatively spaced apart on the base 5, and a movable conductive member 16 provided on the shaft core 2. The fixed conductive plates 17 pass through the base 5 and are electrically connected to the PCB 8. When the shaft core 2 is not pressed, the movable conductive member 16 is located between the two fixed conductive plates 17 and contacts the two fixed conductive plates 17 respectively, and the switch is in a closed state. When the shaft core 2 moves downward, the movable conductive member 16 moves downward with the shaft core 2 and separates from the two fixed conductive plates 17, and the switch is in an open state. The fixed conductive plates 17 are elastic metal plates.

[0084] Furthermore, in one embodiment, Figure 7 As shown, when the switch SW3 is closed, the control element Q2 in the power supply circuit of the magnetic sensor 10 is not conducting, and the power supply circuit cannot normally supply power to the magnetic sensor 10. When the switch SW3 is open, the control element Q2 is conducting, allowing the power supply circuit to normally supply power to the magnetic sensor 10. Q2 can be a transistor or a field effect transistor, or other components that can achieve corresponding control functions, and there is no need to specifically limit it in the present invention.

[0085] In one embodiment of this embodiment, Figure 8 As shown, the switch SW4 is electrically connected to one end of a control element U5. When the switch is disconnected, the end of the control element U5 electrically connected to the magnetic sensor 10 outputs a signal, switching the magnetic sensor 10 into operation. Alternatively, the signal output by U5 can be used to control the on / off switching of the magnetic sensor's operating voltage via a transistor or field-effect transistor. In this embodiment, the control element can be a control chip MCU, or other forms of control element.

[0086] The utility model provides a notebook computer, which uses the magnetic axis keyboard provided by the utility model, can greatly reduce energy consumption and heat generation, and greatly improve the performance and battery life of the notebook computer.

[0087] The utility model also provides a magnetic axis button, such as Figures 1 to 12 As shown, the magnetic axis button includes: a base 5, a guide ring 6 is provided on the inner surface of the base 5, an upper cover 1, the upper cover 1 is connected to the base 5 to form an accommodating space, an elastic member 4, the elastic member 4 is arranged in the accommodating space, a shaft core 2, the lower end of the shaft core 2 is provided with a guide column that cooperates with the guide ring 6, the lower part of the shaft core 2 abuts the elastic member 4, the upper part of the shaft core 2 can slide out of the upper cover 1, the shaft core 2 is connected to a magnetic member 3, and a switch for controlling the working state of the magnetic sensor 10 is also provided in the accommodating space.

[0088] In this embodiment, the upper cover 1 is fastened to the base 5, the elastic member 4 is a spring, the upper portion of the shaft core 2 is a cross shaft, the magnetic member 3 is a magnet, and the elastic member 4 is sleeved on the outside of the guide ring 6 and the guide column. The cross shaft can be used to connect keycaps or other components.

[0089] In this embodiment, the movement of the shaft core 2 can drive the switch to switch between open and closed states. When the shaft core 2 is not pressed, the switch is in an open or closed state. When the shaft core 2 is pressed, the switch switches between open and closed states. The switch can be a normally open switch or a normally closed switch. Whether it is a normally open switch or a normally closed switch, when the shaft core 2 is pressed, the switch switches between open and closed states, and the magnetic sensor 10 enters the working state. When the shaft core 2 is reset, the switch switches between open and closed states again, and the magnetic sensor 10 returns from the working state to the non-working state. The non-working state can be a power-off state or a low-power sleep state.

[0090] like Figure 1 and Figure 2 As shown in the figure, SW1 and SW2 both represent switches, U1 and U3 represent magnetic sensors 10, and U2 represents a control chip. The switches are normally open switches. When the shaft core 2 is not pressed, the switches remain open. When the shaft core 2 is pressed, the switches are closed. Figure 3 and Figure 4As shown, the switch includes a first insulating block 11 arranged on the shaft core 2, and two first conductive plates 7 arranged on the base 5. When the shaft core 2 is not pressed, the first insulating block 11 is located between the two first conductive plates 7. At this time, the switch is in an open state. When the shaft core 2 moves downward, the first insulating block 11 moves downward with the shaft core 2, and the two first conductive plates 7 abut against each other. At this time, the switch is in a closed state. In this embodiment, at least one of the first conductive sheets 7 is an elastic metal sheet. In the initial state, the first insulating block 11 separates the two first conductive sheets 7. At this time, the switch is in the off state. The switch is connected in series to the power supply circuit of the magnetic sensor 10 corresponding to the magnetic axis button. When the switch is off, the magnetic sensor 10 is in an unpowered state, so no power consumption and heat are generated. When the shaft core 2 is pressed, the first insulating block 11 moves downward with the shaft core 2 and no longer separates the two first conductive sheets 7. At this time, under the action of the elastic force, the two first conductive sheets 7 are pressed against each other, and the switch is switched from the off state to the closed state. After releasing the shaft core 2, the shaft core 2 is reset, and the first insulating block 11 moves upward with the shaft core 2 to separate the two first conductive sheets 7 again, and the switch is switched from the closed state to the off state.

[0091] Furthermore, in one embodiment, Figure 5 and Figure 6 As shown, the switch includes two second conductive sheets arranged on the base 5, one of which is a fixed sheet 12 and the other is a spring sheet 13. When the shaft core 2 is not pressed, the spring sheet 13 is not in contact with the fixed sheet 12, and the switch is in an open state. When the shaft core 2 moves downward, the spring sheet 13 contacts the fixed sheet 12, and the switch is in a closed state. Figure 5 and Figure 6 As shown, in this embodiment, when the shaft core 2 moves downward, it pushes the spring piece 13 to move partially and abut against the fixed piece 12. Of course, the abutment can also be achieved by blocking the spring piece 13 from moving toward the fixed piece 12 before the shaft core 2 moves downward, and no longer blocking the spring piece 13 from moving toward the fixed piece 12 after the shaft core 2 moves downward, or other connection forms for achieving abutment are not specifically limited in the present utility model.

[0092] Furthermore, in one embodiment, Figure 1 As shown, SW1 is a switch, one end of SW1 is connected to the positive pole of the power supply and the other end is connected to the VDD power supply pin of the magnetic sensor 10 . SW1 is a normally open switch, and the SW1 is connected in series to the power supply circuit of the magnetic sensor 10 . Figure 1Alternatively, connect one end of SW1 to the GND pin of the magnetic sensor 10 and the other end of SW1 to the GND pin of the power supply. This directly connects the VDD pin of the magnetic sensor 10 to the VDD pin of the power supply. When the button is not pressed, the power supply circuit of the magnetic sensor 10 is disconnected. When the magnetic axis button is pressed, the power supply circuit of the magnetic sensor 10 is switched on. Figure 1 The circuit can also be changed to use a normally open switch to control the B pole of the transistor (or the G pole of the field effect transistor), and then the transistor (or field effect transistor) controls the on and off of VDD or GND of the magnetic sensor 10.

[0093] Furthermore, in one embodiment, Figure 2 As shown, SW2 is a switch, U2 is a control chip, and U3 is a magnetic sensor 10. SW2 is a normally open switch, electrically connected to U2's INPUT terminal, and U2's OUTPUT terminal is connected to the VDD terminal of magnetic sensor 10. When SW2 is closed, U2's OUTPUT terminal, electrically connected to magnetic sensor 10, outputs a signal. In this embodiment, this signal is a voltage signal, which provides an operating voltage to magnetic sensor 10 (U3), switching magnetic sensor 10 into operation. Similarly, with a slight change to the circuit, U2's OUTPUT terminal can be modified to control the GND terminal of magnetic sensor 10 (U3). In this case, magnetic sensor 10 (U3) only operates when U2's OUTPUT terminal outputs a low level, and does not operate when it outputs a high level. Alternatively, U2's OUTPUT terminal can also control the VDD terminal or GND terminal of U3 through a transistor or field-effect transistor.

[0094] Furthermore, in one embodiment, Figure 9 and Figure 10As shown, the switch is a normally closed switch. When the shaft core 2 is not pressed, the switch remains closed. When the shaft core 2 is pressed, the switch is open. The switch includes a second insulating block 14 disposed on the shaft core 2 and two third conductive plates 15 disposed within the base 5. When the shaft core 2 is not pressed, the second insulating block 14 is located above the two third conductive plates 15, and the two third conductive plates 15 abut against each other, and the switch is in a closed state. When the shaft core 2 moves downward, the second insulating block 14 moves downward with the shaft core 2, separating the two third conductive plates 15, and the switch is in an open state. In this embodiment, at least one of the third conductive plates 15 is an elastic metal plate. In the initial state, the third conductive plates 15 abut against each other due to elastic force. When the shaft core 2 moves downward, the second insulating block 14 moves between the two third conductive plates 15 to separate them, opening the switch. In some embodiments, in addition to setting the second insulating block 14 above the third conductive sheet 15, it can also be initially set at a position between the two third conductive sheets 15. When the insulating block 14 moves downward, the third conductive sheets 15 can also be separated to achieve on-off switching of the switch.

[0095] Furthermore, in one embodiment, Figure 11 and Figure 12 As shown, the switch is a normally closed switch, and the switch includes two fixed conductive plates 17 arranged at relative intervals on the base 5, and a movable conductive member 16 arranged on the shaft core 2. When the shaft core 2 is not pressed, the movable conductive member 16 is located between the two fixed conductive plates 17 and contacts the two fixed conductive plates 17 respectively. At this time, the switch is in a closed state. When the shaft core 2 moves downward, the movable conductive member 16 moves downward with the shaft core 2 and separates from the two fixed conductive plates 17. At this time, the switch is in an open state. In this embodiment, the function of the movable conductive member 16 is to connect the two fixed conductive plates 17. After the movable conductive member 16 moves downward with the shaft core 2, the movable conductive member 16 separates from the two fixed conductive plates 17, and the switch is disconnected. Furthermore, in order to ensure that the movable conductive member 16 can smoothly contact the two fixed conductive plates 17, as shown Figure 11 and 12 As shown, the movable conductive member 16 can be in a sheet shape, such as an arch shape. Furthermore, the fixed conductive sheet 17 can be an elastic metal sheet to reduce the requirements for assembly accuracy and processing accuracy.

[0096] The utility model provides a magnetic axis keyboard and a laptop computer, both of which use the magnetic axis keys provided by the utility model, which can greatly reduce energy consumption and heat generation, and greatly improve the performance and battery life of the magnetic axis keyboard and the laptop computer.

[0097] According to one aspect, a method for reducing the power consumption of a magnetic axis keyboard is also provided. When a key of the magnetic axis keyboard is not pressed, the magnetic sensor 10 corresponding to the key is in a non-working state. When a key is pressed, the magnetic sensor 10 corresponding to the key switches to a working state, and the magnetic sensors 10 corresponding to other keys that have not been pressed remain in a non-working state.

[0098] In one embodiment, when the button is not pressed, the power supply circuit of the magnetic sensor 10 corresponding to the button is in an off-circuit state. At this time, the magnetic sensor 10 is in a zero power consumption state. When the magnetic axis button is pressed, the power supply circuit of the magnetic sensor 10 corresponding to the button is switched to a connected state. At this time, the magnetic sensor 10 is in a normal working power consumption state.

[0099] In one embodiment, when the button is not pressed, the power supply circuit of the magnetic sensor 10 corresponding to the button inputs an electrical signal that disables the magnetic sensor 10 from turning on normally. At this time, the magnetic sensor 10 is in a zero power consumption state or an extremely low power consumption standby state. When the button is pressed, the power supply circuit of the magnetic sensor 10 inputs another electrical signal, causing the magnetic sensor 10 to switch to an operating state.

[0100] Furthermore, in one embodiment, the button is provided with a switch for controlling the working state of the magnetic sensor 10. When the button is pressed, the on / off state of the switch is switched, so that the magnetic sensor 10 corresponding to the button is switched to the working state. The switch can be a normally open switch or a normally closed switch.

[0101] When the switch is a normally open switch, when the button is not pressed, the switch remains open, and when the button is pressed, the switch closes, so that the magnetic sensor 10 corresponding to the button is switched to a working state.

[0102] When the switch is a normally closed switch, when the button is not pressed, the switch remains closed, and when the button is pressed, the switch is opened, so that the magnetic sensor 10 corresponding to the button is switched to a working state.

[0103] Furthermore, in one embodiment, when a user uses a button, he or she is accustomed to triggering an input signal at a certain pressing position. In order to adapt to the user's actual usage habits and prevent the magnetic sensor 10 from being mistakenly activated due to accidental touch, in this embodiment, when the button is pressed more than 0.03 mm, the magnetic sensor 10 switches to the working state.

[0104] Furthermore, in one embodiment, when the magnetic sensor 10 switches to an active state, the keyboard provides a visual or audible prompt. Since each magnetic switch on a magnetic keyboard is an independent switch, to facilitate DIY maintenance, in this embodiment, the keyboard includes built-in indicators and / or speakers to provide visual and / or audible prompts when the magnetic sensor 10 switches to an active state.

[0105] In addition, the present invention also provides an electronic device that uses the magnetic axis key or magnetic axis keyboard of the present invention, such as home appliances, kitchen utensils, etc., and is particularly suitable for portable devices such as mice and laptops.

[0106] The above are merely preferred embodiments of the present invention. It should be noted that these preferred embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope of the claims. Persons skilled in the art will appreciate that improvements and modifications may be made without departing from the spirit and scope of the present invention, and such improvements and modifications shall also be considered within the scope of protection of the present invention.
