Description

Illuminated Wheel Module

technical field

The invention relates to a wheel module, in particular to a luminous wheel module applied to a mouse.

Background technique

The mouse is used to control the cursor on the computer screen and thereby operate the computer or computer. In addition to the left and right buttons, the scroll wheel of the mouse is the button most commonly used by ordinary users, for example: use the scroll wheel to browse web pages or move the cursor, or use the scroll wheel to output the middle button signal, or switch between different function modes .

And in order to allow the user to operate the mouse more comfortably, many ergonomic designs are also widely used in the housing of the mouse, as in Figure 1, the mouse 9 includes: a housing 91 and a roller 92, the housing 91 It includes an upper cover 911 and a base 912 , and the control end of the upper cover 911 has an inclination design from upper right to lower left, which makes it more comfortable for users to place their fingers. In addition, in order to improve the convenience of mouse operation in a dark environment and attract consumers' attention, the scroll wheel 92 usually has a light-emitting function. As in Fig. 2A and Fig. 2B, the roller 92 has a groove 921, and the bottom surface of the groove protrudes a rotating shaft 922; The light makes the scroll wheel 92 produce a luminous visual effect; and the middle key switch module 94 is arranged below the rotating shaft 922 .

In the prior art, when the light emitting module 93 is disposed above the rotating shaft 922 (as shown in FIG. 2A ), the light emitting module 93 will be too close to the upper cover 911 , which affects the tilt design of the upper cover 911 . When the roller 92 is pressed, since the light-emitting module 93 does not descend together with the roller 92, the light-emitting unit 932 is too close to the inner peripheral surface of the groove 921, so that the brightness of the roller 92 changes, or even light leakage occurs. When the light emitting module 93 is disposed under the rotating shaft 922 (as shown in FIG. 2B ), the rotating shaft 922 will block the light emitted by the light emitting unit 932 , resulting in a decrease in the brightness of the roller 92 . On the other hand, since the rotating shaft 922 will lean against the middle key switch module 94, when the roller 922 rotates, the rotating shaft 922 which rotates thereupon will constantly rub the middle key switch module 94, making abnormal noise when the roller 92 is operated.
