[0002] With the current consumer market's continuous pursuit of personalized design and application, mouse manufacturers are driven to continuously improve and enhance the various functions of the mouse.

[0003] Currently, DPI mice on the market offer adjustable sensitivity, allowing users to select or set sensitivity parameters based on their needs using a DPI button or the driver. However, in practice, most users are unable to quickly and accurately select or set the appropriate sensitivity, and even more difficult to adjust based on their own usage habits, resulting in less than ideal user experience. Summary of the Invention

[0004] In response to the problems existing in the above-mentioned prior art, the present invention provides a mouse scroll wheel sensitivity adjustment mechanism, an adjustment method and a mouse with adjustable scroll wheel feel. The mechanism can automatically change the magnitude of the axial magnetic force applied to the scroll wheel to achieve the purpose of changing the scroll wheel rotation resistance and automatically adjusting the scroll wheel speed, thereby achieving the purpose of quickly changing the scroll wheel sensitivity, meeting the personalized usage needs of the same user in different application scenarios or different users in the same application scenario, and improving the control feel.

[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is as follows:

[0006] A mouse wheel sensitivity adjustment mechanism is installed in a mouse housing. A circuit board and a positioning shaft are mounted in the mouse housing. A roller is provided in the middle of the positioning shaft. The roller extends to the outside of the mouse housing. Both ends of the positioning shaft extend axially outward from the roller. A first sensor capable of sensing the rotation of the roller is provided on one or both sides of the roller. The first sensor is electrically connected or signal-connected to a main control IC on the circuit board. The mouse wheel sensitivity adjustment mechanism is provided in the mouse housing and includes a first magnetic component and a second magnetic component that can magnetically attract or repel each other, wherein:

[0007] The first magnetic attraction component is fixed on the roller;

[0008] The second magnetic component is mounted on the axial side of the first magnetic component and a second sensor is provided thereon. The second magnetic component is connected to a driving device through a transmission device. The driving device can drive the second magnetic component to approach or move away from the first magnetic component axially to enhance or weaken its magnetic attraction to the scroll wheel and increase or decrease the rotational resistance of the scroll wheel. The transmission device and the driving device are both installed in the mouse housing, and the driving device and the second sensor are both electrically connected or signal-connected to the main control IC.

[0009] As a further elaboration of the above technical solution:

[0010] In the above technical solution, the driving device is a circular motion driving device, and the transmission device can convert the circular motion driving force into a linear motion driving force.

[0011] In the above technical solution, the transmission device is a screw-nut transmission pair, a helical gear transmission pair, or a rack and pinion transmission pair.

[0012] In the above technical solution, the roller is formed with an outer ring, an inner ring and an axial ring that are integrally formed and coaxially arranged, the first magnetic component is matched and embedded on the inner wall of the inner ring, and the positioning shaft is matched and sleeved in the axial ring.

[0013] In the above technical solution, the inner wall of the inner ring and the outer wall of the first magnetic component are both matching wave structures, and the axial thickness of the first magnetic component is smaller than the axial width of the inner ring.

[0014] Another technical solution adopted in the present invention is as follows:

[0015] A method for adjusting the sensitivity of a mouse wheel is provided on a mouse, wherein the mouse wheel sensitivity adjustment mechanism described in the above technical solution is provided. The method for adjusting the sensitivity of a mouse wheel comprises the following steps:

[0016] Step S1 - Tracking the roller speed: The first sensor continuously collects the roller speed V within a recording period t during the roller working period and feeds it back to the main control IC;

[0017] Step S2 - Forward Sensitivity Adjustment: When the V value increases for n consecutive times, the main control IC instructs the driving device to drive the second magnetic component away from the first magnetic component to reduce the rotational resistance of the roller and improve the rotational sensitivity of the roller;

[0018] Step S3 - reverse sensitivity adjustment: when n consecutive V values continue to decrease, the main control IC instructs the driving device to drive the second magnetic attraction component closer to the first magnetic attraction component to increase the rotation resistance of the roller and reduce the rotation sensitivity of the roller.

[0019] As a further elaboration of the above technical solution:

[0020] The above technical solution also includes:

[0021] Step S4 - tracking the position of the second magnetic component: the second sensor feeds back the real-time position Pt of the second magnetic component to the main control IC;

[0022] Step S5 - Recording the habitual position: When the second magnetic component remains stationary for 2n consecutive recording cycles t, the main control IC records the position information of the second magnetic component at this time as the habitual position P1. This continues in this manner until the habitual position Pz is recorded. When the z+1th habitual position is recorded, the first habitual position P1 is deleted and all subsequent habitual positions are replaced with the previous habitual position in sequence.

[0023] Step S6 - calling the habitual position: when the distance between the real-time position Pt of the second magnetic component and the recorded habitual position Px is less than or equal to the deviation value Δ, the main control IC instructs the driving device to drive the second magnetic component to move to the habitual position Px.

[0024] In the above technical solution, the recording period t, the continuous number n, the number of recording times z and the deviation value △ can all be set through the APP and output to the main control IC as logical variables.

[0025] Another technical solution adopted in the present invention is as follows:

[0026] A mouse with an adjustable scroll wheel feel is provided with a scroll wheel and is internally provided with the mouse scroll wheel sensitivity adjustment mechanism described in the above two technical solutions.

[0027] Compared with the prior art, the beneficial effects of the present invention are: by setting a magnetic component, a driving device and a transmission device, the magnitude of the axial magnetic force applied to the roller can be changed, thereby achieving the purpose of changing the roller rotation resistance and automatically adjusting the roller speed, and then achieving the purpose of quickly changing the roller sensitivity to meet the needs of different application scenarios; by setting two sensors, the main control IC can continuously receive the roller speed data and the relative position relationship of the magnetic component, and then accurately analyze and judge the current user's usage needs and usage habits, and quickly execute its judgment results through the driving device, thereby meeting the personalized usage needs of the same user in different application scenarios or different users in the same application scenario, and improving its control feel.

[0035] like Figure 1As shown, the mouse wheel sensitivity adjustment mechanism is installed in the mouse housing. The mouse housing is provided with a circuit board 10 and a positioning shaft 20. A roller 30 is provided in the middle of the positioning shaft 20. The roller 30 extends to the outside of the mouse housing. Both ends of the positioning shaft 20 extend axially outward from the roller 30. A first sensor 40 capable of sensing the rotation of the roller 30 is provided on one side or both sides of the roller 30. The first sensor 40 is electrically connected or signal-connected to the main control IC 50 on the circuit board 10. The mouse wheel sensitivity adjustment mechanism is provided in the mouse housing and includes a first magnetic component 1 and a second magnetic component 2 that can magnetically attract or repel each other, wherein:

[0036] The first magnetic component 1 is fixed on the roller 30;

[0037] The second magnetic component 2 is mounted on the axial side of the first magnetic component 1 and a second sensor 80 is provided thereon. The second magnetic component 2 is connected to a driving device 70 through a transmission device 60. The driving device 70 can drive the second magnetic component 2 to approach or move away from the first magnetic component 1 axially to enhance or weaken its magnetic attraction to the scroll wheel 30 and increase or decrease the rotational resistance of the scroll wheel 30. The transmission device 60 and the driving device 70 are both installed in the mouse housing, and the driving device 70 and the second sensor 80 are both electrically connected or signal-connected to the main control IC 50.

[0038] In this embodiment, the drive device 70 is a micromotor, and the transmission device 60 is capable of converting circular motion driving force into linear motion driving force. It includes a meshing driving bevel gear 61 and a transmission bevel gear 62. The driving bevel gear 61 is in transmission connection with the drive device 70, and the transmission bevel gear 62 is coaxially sleeved in the middle of a transmission shaft 63. The transmission shaft 63 is arranged parallel to and radially adjacent to the positioning shaft 20. A first sensor 40 is provided at one end of the transmission shaft 63. The first magnetic component 1 is a magnet or iron member with an annular structure, and the second magnetic component 2 is a magnet disposed radially inwardly of the first magnetic component 1. In practice, other suitable circular motion driving devices may be selected, and a suitable reversing transmission mechanism such as a screw-nut transmission pair or a rack-and-pinion transmission pair may be selected as the transmission device.

[0039] like Figure 2-3As shown, in this embodiment, the roller 30 is formed with an outer ring 31, an inner ring 32, and a shaft collar 33 that are integrally formed and coaxially arranged. The inner wall of the inner ring 32 is matched with an annular first magnetic component 1, and the shaft collar 33 is matched with a positioning shaft 20. To ensure relative rotation between the first magnetic component 1 and the roller 30 during use and to precisely control the rotation of the roller 30 by the magnetic force, the inner wall of the inner ring 32 and the outer wall of the first magnetic component 1 both have matching wave structures. The axial thickness of the first magnetic component 1 is less than the axial width of the inner ring 32. During assembly, the first magnetic component 1 can be pushed to slide axially on the inner ring 32 to lock it in place within the inner ring 32.

[0040] During use, the movable second magnetic component 2 moves axially toward or away from the first magnetic component 1, increasing or decreasing the axial magnetic attraction force thereon. However, since the roller 30 cannot slide axially on the positioning shaft 20, an equal amount of frictional force is generated between the roller 30 and the positioning shaft 20 or the roller support frame as a reaction force. Under the same external force, this frictional force directly affects the rotational speed of the roller 30 on the positioning shaft 20. By varying the magnitude of the axial magnetic attraction force applied to the roller 30, the present invention can adjust the rotational speed of the roller 30 when the operator applies the same radial external force, thereby achieving the purpose of rapidly changing the sensitivity of the roller and changing the operating feel.

[0041] In order to automatically adjust the magnetic attraction quickly according to the usage situation, such as Figure 4 As shown, the present invention discloses an adjustment method of the above-mentioned adjustment mechanism, comprising the following steps:

[0042] Step S1 - tracking the rotation speed of the roller 30: the first sensor 40 continuously collects the rotation speed V of the roller 30 within a recording period t during the working time and feeds it back to the main control IC 50;

[0043] Step S2 - Forward Sensitivity Adjustment: When n consecutive V values continue to increase, the main control IC 50 instructs the driving device 70 to drive the second magnetic component 2 away from the first magnetic component 1 to reduce the rotational resistance of the roller 30 and improve the rotational sensitivity of the roller 30;

[0044] Step S3 - reverse sensitivity adjustment: when n consecutive V values continue to decrease, the main control IC 50 instructs the driving device 70 to drive the second magnetic component 2 closer to the first magnetic component 1 to increase the rotation resistance of the roller 30 and reduce the rotation sensitivity of the roller 30.

[0045] It is understandable that when the rotation speed of the roller 30 continues to increase, it often means that the user needs to increase the control driving force of the roller to meet his current usage needs. Therefore, the sensitivity of the current roller 30 needs to be improved to reduce the operator's finger fatigue and improve his feel, and vice versa; by continuously receiving and processing the rotation speed data fed back by the first sensor 40 through the main control IC50, it can achieve accurate analysis and judgment of the user's current usage needs, and quickly execute its judgment results through the drive device 70.

[0046] In order to further improve the efficiency of sensitivity adjustment, the present invention further installs a second sensor 80 on the second magnetic component 2, which is electrically connected or signal-connected to the main control IC 50, and performs the following steps with the main control IC 50:

[0047] Step S4 - tracking the position of the second magnetic component 2: the second sensor 8 feeds back the real-time position Pt of the second magnetic component 2 to the main control IC 50;

[0048] Step S5 - Recording the habitual position: When the second magnetic component 2 is stationary for 2n consecutive recording periods t, the main control IC 50 records the position information of the second magnetic component 2 at this time as the habitual position P1. This is repeated until the habitual position Pz is recorded. When the z+1th habitual position is recorded, the first habitual position P1 is deleted and all subsequent habitual positions are replaced with the previous habitual position.

[0049] Step S6 - calling the usual position: when the distance between the real-time position Pt of the second magnetic component 2 and the recorded usual position Px is less than or equal to the deviation value Δ, the main control IC 50 instructs the driving device 70 to drive the second magnetic component 2 to move to the usual position Px.

[0050] During application, the main control IC 50 can record the different needs of the same user for the roller sensitivity in different application scenarios, or different users in the same application scenario, and quickly call the record when it is used next time and instruct the drive device 70 to quickly adjust the second magnetic component 2 into position, so as to quickly respond to the current user and meet his current needs.

[0051] In this embodiment, the recording period t, the continuous number n, the number of recording times z and the deviation value Δ can all be set through the APP and output to the main control IC 50 as logical variables.

[0052] The present invention further discloses a mouse with an adjustable scroll wheel feel. The mouse is provided with a scroll wheel 30 and the mouse scroll wheel sensitivity adjustment mechanism of the above embodiment is provided inside the mouse.

[0053] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
