A circuit board and a positioning shaft are mounted inside the mouse housing. A roller is located in the middle of the positioning shaft, extending to the outside of the mouse housing. Both ends of the positioning shaft extend axially outwards from the roller. A first sensor capable of sensing the rotation of the roller is located on one or both sides of the roller. The first sensor is electrically or signal-connected to the main control IC on the circuit board. The mouse wheel sensitivity adjustment mechanism, located inside the mouse housing, includes a first magnetic attraction component and a second magnetic attraction component that can magnetically attract or repel each other, wherein: The first magnetic attraction component is fixed on the roller; The second magnetic suction component is mounted on the axial side of the first magnetic suction component and has a second sensor mounted on it. The second magnetic suction component is connected to a driving device via a transmission device.

[0016] like Figure 1 As shown, the mouse wheel sensitivity adjustment mechanism is installed inside the mouse housing. A circuit board 10 and a positioning shaft 20 are mounted inside the mouse housing. A roller 30 is located in the middle of the positioning shaft 20, extending to the outside of the mouse housing. Both ends of the positioning shaft 20 extend axially to the outside of the roller 30. A first sensor 40, capable of sensing the rotation of the roller 30, is located on one or both sides of the roller 30. The first sensor 40 is electrically or signal-connected to the main control IC 50 on the circuit board 10. The mouse wheel sensitivity adjustment mechanism, located inside the mouse housing, includes a first magnetic attraction component 1 and a second magnetic attraction component 2 that can magnetically attract or repel each other. The first magnetic attraction component 1 is fixed on the roller 30; The second magnetic suction component 2 is mounted on the axial side of the first magnetic suction component 1 and a second sensor 80 is mounted on it. The second magnetic suction component 2 is connected to a driving device 70 via a transmission device 60. The driving device 70 can drive the second magnetic suction component 2 to move closer to or further away from the first magnetic suction component 1 along the axial direction to enhance or weaken its magnetic attraction to the roller 30 and increase or decrease the rotational resistance of the roller 30. Both the transmission device 60 and the driving device 70 are installed inside the mouse housing. The driving device 70 and the second sensor 80 are both electrically or signal connected to the main control IC 50.

[0017] In this embodiment, the drive device 70 is a micro motor, and the transmission device 60 can convert the circular motion driving force into the linear motion driving force. It includes a meshing drive helical gear 61 and a transmission helical gear 62. The drive helical gear 61 is connected to the drive device 70, and the transmission helical gear 62 is coaxially sleeved in the middle of the transmission shaft 63. The transmission shaft 63 is parallel to the positioning shaft 20 and located radially to its side. A first sensor 40 is located at one end of the transmission shaft 63. The first magnetic attraction component 1 is a ring-shaped magnet or iron piece, and the second magnetic attraction component 2 is a magnet located radially inside the first magnetic attraction component 1. In application, other suitable circular motion drive devices can also be selected, or suitable reversing transmission mechanisms such as lead screw and nut transmission pairs or gear and rack transmission pairs can be selected as the transmission device.

[0018] like Figure 2-3As shown, in this embodiment, the roller 30 has an integrally formed and coaxially arranged outer ring 31, inner ring 32, and shaft collar 33. The inner wall of the inner ring 32 is fitted with a first magnetic attraction component 1 with a ring structure, and the shaft collar 33 is fitted with a positioning shaft 20. In order to ensure that the first magnetic attraction component 1 rotates relative to the roller 30 during use and to accurately control the magnetic attraction force on the rotation of the roller 30, the inner wall of the inner ring 32 and the outer wall of the first magnetic attraction component 1 are both matched with a wave structure. The axial thickness of the first magnetic attraction component 1 is less than the axial width of the inner ring 32. During assembly, the first magnetic attraction component 1 can be pushed to slide axially on the inner ring 32 to lock and fix it in the appropriate position of the inner ring 32.

[0019] During use, the movable second magnetic attraction component 2 moves axially closer to or further away from the first magnetic attraction component 1, generating an increasing or decreasing axial magnetic attraction force. 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 under the same external force. This invention adjusts the rotational speed of the roller 30 by changing the magnitude of the axial magnetic attraction force applied to the roller 30, under the same radial external force applied by the operator, thereby achieving the purpose of quickly changing the roller sensitivity and the operating feel.

[0020] In practical applications, when the rotational speed of the roller 30 continuously increases, it often means that the user needs to increase the driving force of the roller to meet their current usage needs. Therefore, it is necessary to increase the sensitivity of the roller 30 to reduce the operator's finger fatigue and improve their feel, and vice versa. By continuously receiving and processing the rotational speed data fed back by the first sensor 40 through the main control IC 50, the user's current usage needs can be accurately analyzed and judged, and the judgment result can be quickly executed through the drive device 70. Alternatively, the second sensor 80 can provide feedback and the main control IC 50 can record the common position of the second magnetic component 2 to record the different needs of the same user for roller sensitivity in different application scenarios, or different users in the same application scenario. When the user uses the roller 30 again, the record can be quickly recalled and the drive device 70 can be instructed to quickly adjust the second magnetic component 2 into position to respond quickly to the current user and meet their current needs.

[0021] This utility model also discloses a mouse with adjustable scroll wheel feel, wherein the mouse is provided with a scroll wheel 30 and the mouse wheel sensitivity adjustment mechanism of the above embodiment is provided inside the mouse.

[0022] The above does not limit the technical scope of this utility model in any way. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the technical scope of this utility model.
