Description

Technical Field

[0001] The utility model relates to an optimization method for controlling the energy consumption of computer equipment, and in particular to controlling the working state of a magnetic sensor therein, so as to significantly reduce the power consumption of the computer equipment. For example, the utility model can be applied to computer equipment with magnetic axis buttons, and is particularly suitable for portable computer equipment. Background Art

[0002] With the advancement of computer technology, in addition to pursuing computing performance, many scenarios also require minimizing power consumption. Computer keyboards are frequently used and consume a lot of energy. As keyboard technology advances, a variety of keyboards have emerged, and mechanical keyboards are popular with consumers due to their superior tactile feel. Mechanical keyboards have evolved from traditional mechanical keys to those utilizing light and magnetic sensing. For example, starting in the 1980s, mainstream products included mechanical switch keyboards (around 1984), optical switch keyboards (around 2014), and magnetic switch keyboards (around 2019). Magnetic switch keyboards are popular for their faster response and more stable input quality. Magnetic switch keyboards offer more agile key activation, significantly improving typing and gaming speeds. Each magnetic switch key in a magnetic switch keyboard typically includes a magnet and a corresponding magnetic sensor, which detects whether the key is pressed based on the magnetic field and the Hall effect. When the key is not pressed, the magnet maintains a certain distance from the magnetic sensor. When the key is pressed, the magnet approaches the magnetic sensor as the key shaft is pressed down. The magnetic sensor senses the change in the magnetic field and generates a corresponding sensing output. Although magnetic axis keys have excellent performance, on the one hand, the axis structure is large, and if they are to be used in portable computer devices, their space occupancy needs to be optimized. Relevant manufacturers have already made improvements in this regard, such as the improvements made in Chinese patent publication document CN117894621A; on the other hand, in addition to optimizing the structure, each key of the magnetic axis keyboard needs to be configured with a corresponding magnetic sensor. In the existing technology, the magnetic sensor needs to be kept in working state at all times, which makes the magnetic axis keyboard high in energy consumption and heat generation, and requires a larger power supply battery. The increase in the power supply battery not only increases the cost, but also further occupies the overall space of the keyboard and the entire computer device, and will further increase the difficulty of heat dissipation. Therefore, the power consumption of the magnetic axis keys and the entire computer device is high, making the magnetic axis keys not well used on portable computer devices such as laptops. Even on non-portable devices, as the continuous working time increases, the magnet is prone to reduced magnetic induction sensitivity and unstable input. If the heat is severe, it will cause instability of the entire computer device and even significantly shorten its service life. Utility Model Content

[0003] In view of this, the utility model discloses a kind of method for reducing the power consumption of computer equipment, which is used for the computer equipment with magnetic shaft keyboard, characterized in that when the key of magnetic shaft keyboard is not pressed, the magnetic sensor corresponding to the key is in non-working state, when a certain key is pressed, the magnetic sensor corresponding to the key switches to working state, and the magnetic sensor corresponding to other keys not pressed remains in non-working state. This can greatly reduce the power consumption of computer equipment, while also maintaining the high performance advantage of magnetic shaft key. The method of the utility model can be used for various forms of computer equipment, unless specified in the specific scheme, the specific type and structure of computer equipment, magnetic shaft key, magnetic shaft keyboard, control method and the like are not limited. The magnetic sensor of the utility model includes various Hall elements, magnetoresistance elements (including but not limited to AMR, GMR, TMR) and the like in the industry, which refers to any element that can cooperate with a magnetic part to form a Hall effect (or magnetic sensing effect). The specific structure of the key in the utility model can not be limited, as long as the magnetic shaft key that can realize input using magnetic sensing effect can be improved using the utility model, which can realize energy consumption reduction and structure improvement. The realization of magnetic shaft key itself has been common knowledge since mass production products appeared in 2019, unless specifically limited in the utility model, it is not limited to a specific implementation method. Moreover, even for the improvement of magnetic shaft key itself, it does not affect the application of the logic of the control of the working state of the magnetic sensor in the utility model.

[0004] Further, when the key is not pressed, the power supply circuit of the magnetic sensor corresponding to the key is in open circuit state, and when the magnetic shaft key is pressed, the power supply circuit of the magnetic sensor corresponding to the key switches to on-state.

[0005] Further, when the key is not pressed, the power supply circuit of the magnetic sensor corresponding to the key inputs an electric signal to make the magnetic sensor unable to normally start, and when the magnetic shaft key is pressed, the power supply circuit of the magnetic sensor inputs another electric signal to make the magnetic sensor switch to working state.

[0006] Further, the key is provided with a switch for controlling the working state of the magnetic sensor, and when the key is pressed, the on-off state of the switch is switched to make the magnetic sensor corresponding to the key switch to working state.

[0007] Further, when the key is pressed by a distance of more than 0.03mm, the magnetic sensor corresponding to the key switches to working state. When using the key, users are used to triggering input signal at a certain pressing position, so as to adapt to the actual use habit of users and prevent false triggering of the magnetic sensor. This can not only ensure the actual use feeling of users, but also increase the sensitivity of the key.

[0008] Furthermore, when the sensor corresponding to the button switches to a working state, the computer device gives a visual prompt or a sound prompt. For example, a prompt may be given on the keyboard or other location, or a corresponding prompt may be given in the operating system. In order to facilitate the player's operation feedback, increase playability, and also facilitate player maintenance, the keyboard has a built-in indicator light and / or speaker to give visual and / or sound prompts when the magnetic sensor switches to a working state.

The switch can be a normally closed switch, and when the button is not pressed, the switch remains closed, and when the button is pressed, the switch opens, so that the magnetic sensor corresponding to the button switches to the working state. In the present invention, there is no limitation on the specific structure of the normally open or normally closed switch, as long as it can cooperate with the magnetic axis button to realize normally open or normally closed and switch the open and closed states.

[0011] On the other hand, the present invention provides a computer device, including a PCB and a magnetic axis button, wherein the magnetic axis button is connected to the PCB, and a magnetic sensor corresponding to the magnetic axis button is installed on the PCB, characterized in that the magnetic axis button includes a switch for controlling the working state of the magnetic sensor, and 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, and when the magnetic axis button is pressed, the switch is switched between the open and closed states, at which time the magnetic sensor is switched to a working state. In this way, the power consumption of the computer device can be greatly reduced, while the high performance advantage of the magnetic axis button can be maintained. The computer device of the present invention can be a computer device of various forms, and unless otherwise specified in a specific solution, the specific type, structure, control method, etc. of the computer device and the magnetic axis button are not limited.

[0012] Furthermore, the computer device may be a portable computer device, such as a laptop computer. The magnetic axis key comprises a base, an upper cover, an elastic member, and a shaft core. The bottom end of the base is connected to the PCB. A guide ring is provided on the inner surface of the base. The upper cover and the base are connected to form an accommodating space. The elastic member is disposed within the accommodating space. The lower end of the shaft core is provided with a guide post that cooperates with the guide ring.

The upper portion of the shaft core is a cross shaft. The magnetic member is a magnet. The elastic member is sleeved around the guide ring and guide post. The magnetic sensor can be located on the same side of the PCB as the magnetic axis key or on the opposite side. The magnetic sensor can be located directly below or around the magnetic member. The structure of the magnetic axis key itself is currently well known and will not be further described here. Except for special limiting schemes in the present invention, there is no limitation on the type and specific structure of the magnetic axis key, because under the conception of the utility model, the specific structure of the magnetic axis key can be implemented in a variety of ways.

[0014] Furthermore, 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.

[0015] The power supply circuit mentioned in the present invention is a circuit understood in a broad sense.

[0020] Further, the switch can be a normally closed switch, when the magnetic shaft key is not pressed, the switch remains closed, when the magnetic shaft key is pressed, the switch is opened.

[0021] Further, when the switch is closed, a control element in a power supply circuit of the magnetic sensor is not conductive, and the power supply circuit cannot normally supply power to the magnetic sensor, when the switch is opened, the control element is conductive, so that the power supply circuit normally supplies power to the magnetic sensor.

[0022] Further, the switch can be electrically connected with one end of a control element, when the switch is opened, the end of the control element electrically connected with the magnetic sensor outputs a signal, so that the magnetic sensor switches to a working state.

DETAILED DESCRIPTION

[0041] The present invention provides a method for reducing power consumption of a computer device. The method is used for a computer device having a magnetic axis keyboard. The magnetic axis keyboard described herein can be, for example, Figure 13 A single magnetic axis keyboard as shown in Figure 14 As shown in FIG, a magnetic axis keyboard integrated into a portable computer device (a laptop computer) is shown. In conjunction with other corresponding figures, when a key on the magnetic axis keyboard is not pressed, the magnetic sensor 10 corresponding to the key is in a non-operating state. When a key is pressed, the magnetic sensor 10 corresponding to the key switches to an operating state, while the magnetic sensors 10 corresponding to the other unpressed keys remain in a non-operating state. The non-operating state is a power-off state or a dormant state where power consumption is significantly less than 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 switches from the non-operating state to the operating state, where the power consumption of the magnetic sensor is normal, ensuring normal magnetic induction. This significantly reduces the power consumption of the computer device and the heat generated by the computer device, thereby reducing the occurrence of high-temperature sensor failure and instability. Furthermore, for portable battery-powered computers, this solves the heating problem caused by large-capacity batteries and increases the operating time between a single charge or battery replacement. This significantly expands the use cases of magnetic axis keys or magnetic axis keyboards, making them more easily adaptable to portable computer devices.

[0042] One implementation method is as follows Figure 1As shown, when the key is not pressed, the power supply circuit of the magnetic sensor 10 corresponding to the key is in an open state, at this time, the magnetic sensor 10 is in a 0 power consumption state, when the magnetic key is pressed, the power supply circuit of the magnetic sensor 10 corresponding to the key is switched to a closed state, at this time, the magnetic sensor 10 is in a normal working power consumption state. In the open state, the magnetic sensor is not connected to the power supply circuit, at this time the magnetic sensor will not produce power consumption and will not produce heat.

[0043] Further, in one embodiment, as shown in Figure 1 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 in the power supply circuit of the magnetic sensor 10. Figure 1 SW1 can also be connected to the GND pin of the magnetic sensor 10, and the other end of SW1 is connected to the GND of the power supply, at this time the VDD of the magnetic sensor 10 is directly connected to the VDD of the power supply. When the key is not pressed, the power supply circuit of the magnetic sensor 10 is in an open state, when the magnetic key is pressed, the power supply circuit of the magnetic sensor 10 is switched to a closed state. Figure 1 The circuit of the magnetic sensor 10 can also be changed to use a normally open switch to control the B electrode of the triode (or the G electrode of the field effect tube), and then the triode (or field effect tube) controls the VDD or GND of the magnetic sensor 10.

[0044] In one embodiment, as shown in Figure 2 When the key is not pressed, the power supply circuit of the magnetic sensor 10 corresponding to the key inputs an electrical signal to make the magnetic sensor 10 unable to normally start, at this time the magnetic sensor 10 is in a 0 power consumption state or an extremely low power consumption standby state, and the heat generated is greatly reduced. When the key is pressed, the power supply circuit of the magnetic sensor 10 inputs another electrical signal to make the magnetic sensor 10 switch to a working state.

[0045] Further, in one embodiment, as shown in Figure 2As 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.

[0046] 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.

[0047] 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.

[0048] 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 2In 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.

[0049] 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.

[0050] Furthermore, in one embodiment, the switch is a normally closed switch, such as Figure 7 and Figure 8 ,for Figure 7 or Figure 8 With a slight modification to the existing circuit, the normally closed switch can be connected to either the power supply GND or VDD. When the button is not pressed, the switch remains closed. When the magnetic axis button is pressed, the switch opens, switching the magnetic sensor to the working state. Figure 7 In this example, U4 is a magnetic sensor, R1 is a resistor, and SW3 is a switch. SW3 is electrically connected to one end of the transistor or field-effect transistor Q2. Normally, SW3 is closed, Q2 is cut off, and U4's GND pin is disconnected from the power supply GND, so it does not work. When SW3 is disconnected, Q2 is turned on, U4's GND pin is connected to the power supply GND, and U4 operates normally. Figure 7 With a slight modification to the circuit, SW3 can also be changed to control the on and off of U4's VDD through a transistor or field effect transistor. Figure 8In this circuit, U6 is the magnetic sensor, U5 is the control chip, and SW4 is the switch. SW4 is electrically connected to one of U5's input terminals, and one of U5's output terminals is electrically connected to U6's VDD terminal. Normally, when SW4 is closed, U5's output terminal outputs a low level, and U6 does not operate. When SW4 is open, U5's output terminal outputs a high level, and U6 operates normally. Similarly, with a slight change in the circuit, U5's output terminal can be changed to control the GND terminal of magnetic sensor U6. In this case, magnetic sensor U6 only operates when U5's output terminal outputs a low level, and does not operate when it outputs a high level. U5's output terminal can also control the on / off of U6's VDD or GND through a field-effect transistor or transistor. U5 can be an MCU, or other chip or other electronic component that can perform the corresponding function. For magnetic sensors with an EN terminal (enable terminal), the normally closed switch described above can directly input a switch closing or opening signal to the EN terminal of the magnetic sensor. That is, when the switch is closed, the magnetic sensor is in a low-power standby state. When the switch is opened, the magnetic sensor exits the standby state and starts working.

[0051] 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.

[0052] Furthermore, in one embodiment, when the magnetic sensor 10 is switched to the working state, the computer device may give a visual prompt or a sound prompt, for example, an element on the keyboard may give a visual or sound prompt.

[0053] Furthermore, the computer device is preferably a portable computer device, such as a laptop computer, which uses the method of the present invention to greatly reduce energy consumption and heat generation, and greatly improve the performance and battery life of the laptop computer.

[0054] Another aspect of the present invention provides a computer device comprising: a PCB 8 and a magnetic axis key, the magnetic axis key being connected to the PCB 8, a magnetic sensor 10 corresponding to the key being mounted on the PCB 8, and the magnetic axis key including a switch for controlling the operating state of the magnetic sensor 10. When the magnetic axis key is not pressed, the switch is in an open or closed state, and the magnetic sensor 10 is in an inoperative state. When the magnetic axis key is pressed, the switch switches between an open and closed state, and the magnetic sensor 10 is switched to an operative state.

[0055] In a further embodiment, the computer device may be a portable computer device, and the portable computer device may be a notebook computer.

[0056] To illustrate the implementation of the key structure of the present invention, 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 a housing. The elastic member 4 is disposed in the housing. 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 housing is also provided with 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. The magnetic sensor 10 can be arranged on the same side or the opposite side of the PCB 8 and the magnetic axis button. The magnetic sensor 10 can be arranged directly below the magnetic component 4 or at a peripheral position of the magnetic component 4.

[0057] Furthermore, in one embodiment, Figure 3 and Figure 4 As shown, in the computer device provided in this embodiment, 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 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.

[0058] Furthermore, in one embodiment, Figure 5 、 Figure 6As shown, in the computer device provided in this embodiment, the switch is also a normally open switch. The switch includes two second conductive plates arranged on the base 5. The second conductive plates pass through the base 5 and are electrically connected to the PCB 8. In this embodiment, the second conductive plates are also connected to the PCB 8 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.

[0059] In order to demonstrate the implementation of the circuit of the present utility model, in one embodiment, as Figure 1 As shown, in the computer device 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 shaft core 2 is not pressed, the power supply circuit of the magnetic sensor 10 is in an open state. When the magnetic shaft button 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.

[0060] Furthermore, in one embodiment, Figure 2 As shown, in the computer device 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 operation.
