Description

TECHNICAL FIELD

[0001] The utility model relates to a technical field of input device, especially relates to a scroll wheel device and mouse. BACKGROUND

[0002] Mouse is the input device commonly used in computer equipment at present, can pass through its with computer equipment and carry out interaction, and then control pointer movement and page scrolling etc., wherein the realization of page scrolling is through the scroll wheel on the mouse, the mouse used at present is usually provided with encoder, the scroll wheel is connected to the encoder and drives the rotator to rotate to produce control signal, the rotator type encoder will have paragraph feeling when rotating due to its structure, and there is resistance when rotating, need to realize only through fast operation scroll wheel when quickly scrolling the page, there is the problem of slow response speed, and the process of fast operation will bring greater noise, the paragraph feeling in the scroll wheel of the mouse of the prior art can guarantee the accurate operation of the user, but when quickly scrolling, the purpose is to quickly browse the page, at this moment, paragraph feeling will affect efficiency, and the existence of damping is not convenient for continuous quick browsing.

[0003] If a scroll wheel device and mouse capable of automatically switching paragraph damping and dampingless can be provided, the user can be provided with better use experience. UTILITY MODEL CONTENT

[0004] The utility model solves the technical problem that the prior art is lack of, and provides a scroll wheel device and mouse capable of automatically switching paragraph damping and dampingless, and having fast response speed and good working stability.

[0005] The utility model adopts the technical scheme that the scroll wheel device includes base, scroll wheel assembly and sensor group, the scroll wheel assembly includes inner wheel and outer wheel, the base is provided with mounting shaft, the inner wheel and the outer wheel are all rotationally fitted on the mounting shaft, the inner edge of the outer wheel is provided with gear ring, the gear ring is transmissionally fitted with the main gear provided on the inner wheel through planetary gear set, at least two groups of first magnetic bodies are sequentially arranged on the mounting shaft along the circumferential direction, a plurality of sliding grooves are arranged in the circumferal array on the inner wheel, and each sliding groove is slidably fitted with second magnetic body, the second magnetic body is magnetically attracted to the adjacent first magnetic body, the polarity installation direction of all the first magnetic bodies along the circumferential direction of the mounting shaft is same, the polarity installation direction of all the second magnetic bodies along the circumferential direction of the inner wheel is same, and the sensor group is magnetically inducted to the second magnetic body.

[0006] As can be seen from the above scheme, the transmission between the inner wheel and the outer wheel is realized by cooperation of the gear ring, the planetary gear set and the main gear, and the main gear with a small diameter is driven to rotate by the gear ring with a large diameter, thereby realizing amplification of the rotating speed. The user can adjust the rotating speed of the inner wheel by controlling the rotating speed of the outer wheel, the inertia force borne by the second magnetic bodies changes with the change of the rotating speed, and when the rotating speed increases, the inertia force increases, so that the inertia force is greater than the magnetic force from the first magnetic bodies, thereby enabling the second magnetic bodies to move away from the first magnetic bodies. After moving away, the magnetic force between the second magnetic bodies and the first magnetic bodies decreases, and the paragraph feeling damping is eliminated due to the magnetic attraction between the second magnetic bodies and the first magnetic bodies. The inner wheel and the outer wheel enter a high-speed rotating state without damping. When switching, the user only needs to adjust the speed and force applied to the roller to switch, which is more convenient. In the slow state, the paragraph feeling damping can be realized by the magnetic attraction cooperation between the second magnetic bodies and the first magnetic bodies, thereby enabling the user to perform accurate operation. The high-sensitivity roller signal feedback is realized by the magnetic induction detection of the second magnetic bodies and the sensor group. The polarity distribution of the first magnetic bodies and the second magnetic bodies can ensure that the overall damping of the inner wheel is consistent and uniform at any angle.

[0022] In the stationary state, the plurality of second magnetic bodies 213 are close to the mounting shaft 11 under the magnetic attraction of the adjacent first magnetic bodies 12.

[0023] As Figure 7 shown, when the outer wheel 22 is slowly rolled, the inner wheel 21 rotates under the drive of the planetary gear set, and the second magnetic bodies 213 are kept close to the mounting shaft 11 under the magnetic attraction and cooperate with the first magnetic body 12 to generate paragraph damping; as Figure 8 shown, when the outer wheel 22 is quickly rolled, the inner wheel 21 rotates under the drive of the planetary gear set, and the inertia force of the second magnetic bodies 213 is greater than the magnetic force between the second magnetic bodies 213 and the first magnetic body 12 when rotating at high speed, so that the second magnetic bodies 213 are all away from the rotating shaft 11, at this time the roller assembly 2 enters the fast rotating state without paragraph damping;

When rotating without damping, the roller assembly 2 will exist inertia under the action of the second magnetic body 213 distribution, and the user does not need to repeatedly push the roller assembly 2. Whether in high speed or low speed, the noise generated by the internal interference is small.
