Description

Technical Field

[0001] This utility model relates to the field of mouse technology, and in particular to a mouse scroll wheel device and a mouse. Background Technology

[0002] As one of the most important human-computer interaction devices, the mouse's scroll wheel is primarily responsible for vertical scrolling of documents, web pages, and other content. Traditional mouse scroll wheels mostly use mechanical encoders or optical sensors to achieve stepped (toothed) scrolling detection. When browsing long documents or quickly turning pages, if the scroll wheel is in toothed mode, it needs to slide up and down with resistance, and each rotation slides several increments. To achieve fast page turning, multiple forceful flicks are required, making the operation inconvenient and inefficient.

[0003] The applicant has researched a method for implementing a rapid scroll wheel. In addition to the standard mouse buttons, a function button is provided. When this function button is released, the mouse wheel functions as a standard mouse wheel. When the function button is pressed, the process is as follows: Step 1: The scroll wheel enters the default rapid mode state. Step 2: In the default rapid mode state, when the user triggers the first scroll up or down event, the event is reported normally. Afterward, the scroll up or down event is automatically repeated at a set frequency, i.e., entering the rapid mode repetition state. Step 3: The rapid mode repetition state automatically stops when the user triggers any of the following situations: Situation 3-1: The user scrolls one notch in the opposite direction, the automatic repetition stops, and the system returns to the default rapid mode state, i.e., returns to Step 1, continuously detecting subsequent user input; Situation 3-2: The user releases the function button, the automatic repetition stops, the system leaves rapid mode, and returns to the standard mouse wheel function.

[0004] In other words, in rapid scroll wheel mode, you need to hold down the function button. However, many users are still accustomed to scrolling the mouse while browsing.

[0005] In addition, some mice integrate left and right tilt click functions into the scroll wheel, but these are usually only used as a simple on / off switch. The triggering effect and speed are fixed, and they cannot achieve fine linear control. The functionality is limited, and the user experience needs to be improved.

[0006] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

When the roller is turned, different toothed grooves are switched to adapt to the third horizontal arm.

[0016] As a preferred embodiment, it further includes: a sway sensing module; the sway sensing module is electrically connected to the MCU; the front and rear ends of the roller bracket have swing shafts, and the left and right sides of the front or rear ends of the roller bracket have swing triggering parts; the swing triggering parts are adapted to the sway sensing module;

[0017] The MCU is also configured to output left and right movement commands, page turning commands, or task switching commands based on the lateral movement signal fed back by the lateral movement sensing module.

[0040] Please refer to Figures 1 to 12 As shown, it illustrates a specific embodiment of the present invention.

[0041] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] like Figures 1 to 4 As shown, a mouse scroll wheel device, specifically a mouse scroll wheel device with scroll wheel mode switching and side swing triggering functions, includes: scroll wheel bracket 10, scroll wheel 20, MCU, scroll wheel detection sensor 40, and mode switching switch 50.

[0043] The roller 20 is rotatably mounted on the roller bracket 10. The roller 20 includes a roller shaft (with grids), a roller outer ring (made of metal or plastic, etc.), a sliding bearing core, and a sliding bearing sleeve. The sliding bearing sleeve is fitted around the outer circumference of the sliding bearing core and passes through the center of the roller shaft in the left-right direction. The roller outer ring is mounted on the roller shaft. The roller detection sensor 40 is disposed on the roller bracket 10 and is used to detect the rotation of the roller 20 and generate a rolling signal. The roller detection sensor 40 and the mode switch 50 are electrically connected to the MCU. The signal output terminal of the mode switch 50 can be connected to a GPIO pin (general purpose input / output) of the MCU. The MCU is configured to detect the trigger signal of the mode switching switch, and generate a switching command when the number of triggers reaches a preset threshold N within a preset time interval (e.g., within 2 seconds, typically measured by a built-in timer / counter in the MCU), where N ≥ 2 (in this embodiment, the preset threshold N = 3). In actual operation, the mode switching switch 50 is clicked N times rapidly. Each time the mode switching switch 50 is pressed and released, a potential change (from high level to low level or from low level to high level) is generated, and the MCU counts by detecting this signal. The MCU is also configured to respond to the switching command and enter a multiplier scrolling mode; in the multiplier scrolling mode, the MCU outputs (e.g., sends to a computer) a scrolling command amplified by M times based on the scrolling signal emitted by the scroll detection sensor, where M ≥ 2.

[0044] To switch to standard mode, simply tap the mode switch 50 times.

[0045] The mode switching switch 50 is mounted on the scroll wheel bracket 10 and faces upwards. The mode switching switches 50 are spaced apart on the front or rear side of the scroll wheel 20. The structure is compact, the layout is reasonable, and the operation is convenient. For example, when using a mouse with the right hand, it is very convenient to click the mode switching switch 50 and scroll the scroll wheel 20, which conforms to the operating habits and provides a good user experience.

[0046] In this embodiment, as Figure 4As shown, the roller bracket 10 is an integral injection molded part. The roller bracket 10 has a first mounting cavity 101 and a second mounting cavity 102. The roller 20 is located in the first mounting cavity 101, and the mode switch 50 is located in the second mounting cavity 102. Vertical guide grooves 103 are provided on the left and right side walls of the second mounting cavity 102. Correspondingly, guide blocks 51 are provided on the left and right sides of the mode switch 50. The guide blocks 51 are adapted to the corresponding vertical guide grooves 103. When the mode switch 50 is clicked / pressed, the guide blocks 51 move up and down along the vertical guide grooves 103. The mode switch 50 automatically resets elastically after being clicked downwards. In this embodiment, an elastic connection is formed by an elastic link 80. The elastic link 80 is generally made of metal and is S-shaped, including a first horizontal arm 81, a first oblique arm 82, a second horizontal arm 83, a second oblique arm 84, and a third horizontal arm 85 connected in sequence. The first horizontal arm is engaged with the mode switch 50 to provide an elastic force for the mode switch 50 to reset upwards. The second horizontal arm is mounted on the roller bracket 10 to form a relatively fixed relationship. The third horizontal arm is adapted to the toothed groove on the outer circumference of the roller shaft. When the roller 20 is turned, different toothed grooves are switched to adapt to the third horizontal arm. The positions of the first horizontal arm and the third horizontal arm are both higher than the second horizontal arm. In the elastic structure formed by the first horizontal arm, the first oblique arm, and the second horizontal arm, the first horizontal arm is equivalent to a free end, and the second horizontal arm is equivalent to a fixed end. In the elastic structure formed by the second horizontal arm, the second oblique arm, and the third horizontal arm, the third horizontal arm is equivalent to a free end, and the second horizontal arm is equivalent to a fixed end.

[0047] like Figure 9As shown, the roller detection sensor 40 is used to detect the rotational movement and number of rotations of the roller 20. The roller detection sensor can adopt an infrared phototransistor (IR PT) scheme or a linear Hall sensor scheme. If an infrared phototransistor (IR PT, infrared emitter and receiver) is used, the roller detection sensor 40 includes an FPC and an infrared phototransistor 41 disposed on the FPC 40, and its output terminal is connected to the GPIO pin of the MCU. The FPC is provided with a clearance hole for the side post where the vertical guide groove 103 is located to pass through. The FPC extends into the second mounting cavity 102. Furthermore, a stop block 104 is provided on the side post where the other vertical guide groove 103 is located, protruding towards the second mounting cavity 102, to stop the top surface of the FPC. The top of the stop block 104 is an inclined guide surface, so that the FPC nests from top to bottom into the side post where the vertical guide groove 103 is located, passes over the stop block 104, and is locked into the second mounting cavity 102. Multiple electrical connection points are provided on the FPC for corresponding electrical connections to the pins at the lower end of the mode switching switch 50. The FPC is electrically connected to the PCB board 30. When the roller 20 rotates, the grid blocks the infrared light, and the receiving tube outputs a continuous pulse signal to the GPIO pin of the MCU, outputting a pulse sequence. The MCU determines the number of scrolls by the number of pulses. If a linear Hall sensor is used, its output is connected to one of the analog-to-digital converter (ADC) pins of the MCU. The rotation of the magnet on the roller shaft causes the analog voltage generated by the Hall element to change periodically. This analog voltage signal is connected to the MCU's analog-to-digital converter (ADC) pin, outputting a periodically changing analog voltage. That is, the MCU determines the number of scrolls and the speed by sampling and calculating the voltage change period through the ADC. In the multiplier scrolling mode, the MCU is configured to multiply the original scrolling signal collected by the roller detection sensor; that is, for every physical scroll of one row, the MCU sends a scrolling command of M rows (M≥2, such as 3, 5, 10, etc.) to the computer host, thereby achieving rapid page turning.

[0048] Based on the aforementioned mouse scroll wheel device, a scroll wheel mode switching recognition process is provided, including the following steps:

[0049] Step S101: System initialization, clear counter N, and turn off timer.

[0050] Step S102: The MCU continuously detects whether the mode switching switch 50 is pressed.

[0051] Step S103: Once the mode switching switch 50 is detected to be pressed, the MCU first determines whether a preset timer (e.g., a timer for determining the interval between consecutive clicks) is still running (i.e., whether it is within the preset time window).

[0052] Step S104: If the timer is still running, it means that this click is a continuous operation, so increment the counter N by 1.

[0053] Step S105: If the timer has not run or has timed out, it indicates that this is a new operation sequence. In this case, the counter N is reset to 1, and the timer is restarted.

[0054] Step S106: Determine whether the value of counter N has reached the preset threshold (e.g., 3 times).

[0055] Step S107: If the threshold is reached, the MCU performs a switching action, changes the working mode of the scroll wheel 20 (e.g., switching between standard mode and multiplier mode), then clears the counter N and turns off the timer.

[0056] Step S108: If the threshold is not reached, the process ends and the system waits for the next triggering of mode switching switch 50.

[0057] Based on the aforementioned mouse scroll wheel device, a processing flow for scroll wheel scrolling signals is provided, including the following steps:

[0058] Step S201: The MCU detects the number of scrolls of the roller 20 through the roller detection sensor 40.

[0059] Step S202: The MCU determines whether it is currently in the multiplier scrolling mode.

[0060] Step S203: If in the multiplier scrolling mode, the MCU will multiply the actual number of scrolling grids detected by the MCU by a preset multiplier coefficient M (M≥2) to generate the final scrolling instruction.

[0061] Step S204: If not in multiplier scrolling mode, the MCU will use the actual number of scrolls as the final scrolling instruction.

[0062] Step S205: The MCU sends the final scrolling command to the computer via the USB interface. Alternatively, it sends the final scrolling command to the computer via a wireless communication module.

[0063] Based on the aforementioned mouse wheel device, a mouse wheel speed control process is provided, including the following steps:

[0064] Step S301 (Detection Step): Detect the number of times the mode switching switch 50 is triggered within a preset time interval;

[0065] Step S302 (Mode Switching Step): When the number of triggers reaches a preset threshold N times, control the scroll wheel to enter the multiplier scrolling mode;

[0066] Step S303 (Signal Processing Step): In the multiplier scrolling mode, based on the received scrolling signal, a scrolling command amplified by M times (M≥2) is sent to the computer.

[0067] like Figure 9 As shown, this mouse scroll wheel device further includes: a side-sway sensing module; the side-sway sensing module is electrically connected to the MCU; the scroll wheel bracket 10 has a swing shaft 11 at its front and rear ends, the swing shaft 11 is mounted on the mouse body, so that the scroll wheel bracket 10 can swing left and right relative to the mouse body around the swing shaft 11; the left and right sides of the front or rear end of the scroll wheel bracket 10 are each extended with a swing trigger part 12, the swing trigger part 12 can be two legs extending outward from the left and right sides of the scroll wheel bracket 10; the swing trigger part 12 is adapted to the side-sway sensing module; the MCU is also configured to output left and right movement or page turning commands based on the side-sway signal fed back by the side-sway sensing module.

[0068] like Figure 10 As shown, the side-swing sensing module includes two push switches, such as tactile switches 60, which are provided on the left and right sides of the swing trigger part 12. Tactile switches are technically mature, low-cost, reliable in structure, and highly durable. While achieving powerful functions, they do not put significant pressure on the overall cost and manufacturing process of the product. The push switch is electrically connected to the MCU (e.g., the signal output terminal of the tactile switch is electrically connected to another GPIO pin of the MCU). When the user applies lateral pressure to the roller 20, it can overcome the resistance of the internal reset mechanism (such as a spring or rubber pad). The roller 20 swings laterally under the action of external force, deflecting at a certain angle, so that the swing trigger 12 physically presses the push switch, making it conduct and sending a low-level (or high-level) signal to the GPIO pin of the MCU. The MCU only needs to detect whether there is this level signal. The MCU is also configured to output a preset left and right movement or page turning command when the push switch is triggered. Specifically, when the signal of the tactile switch being triggered is detected, a preset command is output to the computer host. This command can be mapped to the left and right scrolling or forward and backward page turning function of a webpage or document, or any function such as task switching.

[0069] A PCB board 30 is disposed below the scroll wheel bracket 10. The MCU and the tactile switch 60 of the side-swing sensing module are respectively disposed on the PCB board 30. Of course, the MCU is not limited to being disposed on the PCB board 30, as long as the MCU is electrically connected to the PCB board. A scroll wheel press switch 70 is also disposed on the PCB board 30. A press trigger part 13 extends below the swing shaft 11 at one end (e.g., the front end) of the scroll wheel bracket 10 for triggering the scroll wheel press switch 70 downward. The mode switching switch 50 is disposed above the swing shaft 11 at the other end (e.g., the rear end). Typically, a power management module is also configured on the PCB board 30. For wired mice, it draws power from the computer's USB interface (USB_VBUS) and converts it into a stable operating voltage (e.g., 3.3V) required by the various components of the system (especially the MCU and various sensors). At the same time, the USB interface is responsible for communicating with the computer and transmitting the final instruction data generated by the MCU to the computer. For wireless mice, they communicate wirelessly with the computer and have a built-in power supply connected to a power management module.

[0070] like Figures 6 to 8 As shown, the lateral swing sensing module is an analog sensor, and its signal output terminal is electrically connected to the MCU (for example, its signal output terminal is electrically connected to the analog-to-digital converter (ADC) pin of the MCU). When the roller 20 is subjected to an external force and swings laterally, the larger the swing angle, the larger the voltage at the signal output terminal. The MCU outputs a left or right movement command or a page-turning command with a corresponding speed based on the detected voltage value, and the larger the voltage value, the greater the speed.

[0071] in, Figure 6 and Figure 7 This demonstrates the magnet-Hall scheme, combined with Figure 11 As shown, specifically: the swing trigger unit 12 is equipped with a magnet 62, and a recessed cavity matching the shape of the magnet is recessed at the top of the support leg (the lower end is a blind end). The magnet 62 is inserted into the cavity from top to bottom. The side swing sensing module includes two linear Hall elements 61 corresponding to the left and right sides of the swing trigger unit 12. When the roller 20 is subjected to an external force and swings laterally, it causes its magnet 62 to move closer to or away from a fixed linear Hall element 61. The change in distance causes a change in magnetic field strength, resulting in a change in the analog voltage output by the Hall element 61. This voltage is connected to the ADC pin of the MCU. The larger the swing angle, the closer the magnet 62 is to the Hall element 61, and the larger the voltage at the signal output terminal.

[0072] Figure 8 The pressure sensor solution was shown, combined with Figure 12As shown, specifically: the side swing sensing module includes two pressure sensors 63 corresponding to the left and right swing trigger parts 12; when the roller 20 is subjected to external force and swings laterally, the swing trigger part 12 squeezes a pressure sensor 63. The larger the swing angle, the greater the pressure on the pressure sensor 63, and the higher the analog voltage output by the pressure sensor 63; this voltage is connected to the ADC pin of the MCU.

[0073] Similarly, the magnet-Hall effect and pressure sensor solutions both have advantages such as mature technology, reliable structure, high durability, and controllable cost. Therefore, while achieving powerful functions, they will not put significant pressure on the overall cost and manufacturing process of the product.

[0074] Based on the aforementioned mouse scroll wheel device, a processing flow for the scroll wheel oscillation signal is provided, including the following steps:

[0075] Step S401 (Data Acquisition Step): The MCU continuously acquires analog voltage values ​​from the linear Hall sensor 61 or the pressure sensor 63 through its ADC pin.

[0076] Step S402 (Speed ​​Mapping Step): The MCU calculates / maps the collected voltage value to the corresponding left and right scrolling speed. The higher the voltage value, the faster the speed.

[0077] Step S403 (Instruction Output Step): The MCU sends a left / right movement command or page-turning command at the specified speed to the computer via the USB interface. Alternatively, it sends the left / right movement command or page-turning command at the specified speed to the computer via the wireless communication module. This achieves intuitive and precise control, where "a larger deflection results in a faster speed, and a smaller deflection results in a slower speed."

[0078] In practical applications, this mouse wheel device, which can sense the lateral tilt amplitude and output linear speed, has great potential demand in scenarios such as video editing timeline zooming, horizontal browsing of large tables, rotation of 3D design software models, and horizontal browsing of long web pages. It is of great significance to improving the efficiency of human-computer interaction in professional fields. Users can steplessly and precisely control the horizontal scrolling speed by controlling the tilt angle, and the operating experience is far superior to the traditional on / off lateral tilt mechanism.

[0079] Furthermore, a mouse is provided that incorporates a mouse scroll wheel device as described in any of the preceding claims. The mouse scroll wheel device used in the mouse may have the aforementioned scroll wheel mode switching function and / or side-swing trigger function (left and right sway function).

[0080] The key design feature of this invention lies in its use of an MCU, a scroll wheel detection sensor, and a mode switching switch to enable a multi-scroll mode through a specific interaction method: clicking the switch N times in quick succession. This method is intuitive, efficient, and highly recognizable, effectively preventing accidental triggering. It also caters to the needs of many users who still prefer to scroll while browsing. In multi-scroll mode, even slight physical scrolling by the user is transformed into rapid scrolling of screen content, greatly improving the efficiency of browsing long documents and web pages. This addresses the user pain point of inconvenient and inefficient fast scrolling, enhancing the user experience.

[0081] Secondly, the side-swing trigger function provides additional programmable buttons, enriching the mouse's operational dimensions. In particular, the side-swing sensor module is designed as an analog sensor, with its signal output terminal electrically connected to the MCU. When the scroll wheel is subjected to external force and swings sideways, the larger the swing angle, the greater the voltage at the signal output terminal. The MCU outputs corresponding left and right movement or page-turning commands based on the detected voltage value. In this way, efficient fast scrolling and convenient side-swing trigger function are integrated into one, fully meeting the ultimate pursuit of mouse operation efficiency in modern office, programming, and entertainment, resulting in a leapfrog improvement in user experience.

[0082] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
