Description

Luminous roller structure

The present invention relates to a scroll wheel structure, in particular to a luminous scroll wheel structure applied to a mouse.

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 most commonly used button by ordinary users, for example: use the scroll wheel to browse the webpage or move the cursor, or use the scroll wheel to output the middle key 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 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 allows users to place fingers more comfortably. 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. 2A and 2B, the roller 92 has a groove 921, and the bottom surface of the groove 921 protrudes a rotating shaft 922; the light emitting module 93 includes a circuit board 931 and a light emitting unit 932, and the light emitting unit 932 is used to face the roller 92 emits light so that the scroll wheel 92 produces 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 fall 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. In addition, since the light-emitting module 93 is located above the rotating shaft 922, when the light-emitting unit 932 emits light, the light cannot effectively irradiate the area below the rotating shaft 922, so that the partial area of the roller 92 will appear dark. 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 . In addition, as shown in FIG. 2A and FIG. 2B , the circuit board 931 of the light emitting module 93 needs to penetrate into the groove 921 of the roller 92 , which will increase the difficulty of assembly. Furthermore, as shown in FIG. 2A and FIG. 2B , the circuit board 931 of the light source module 93 will be exposed from the gap between the roller 92 and the upper cover 911, which will cause the circuit board 931 of the light source module 93 to suffer from electrostatic discharge (ESD). The chances of destruction are greatly increased.

Therefore, how to improve the above problems is actually the focus of attention of relevant people in the field.
