Description

Luminous roller structure

The present invention relates to a roller structure, and in particular to a luminous roller 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 mouse wheel is the most commonly used button by ordinary users. For example, using the wheel to browse web pages or move the cursor, or pressing the wheel to output the middle button signal, or switching between different function modes. .

In order to make the user more comfortable when operating the mouse, many ergonomic designs are also widely used in the mouse casing. As shown in Figure 1, the mouse 9 includes: a casing 91 and a roller 92. The casing 91 includes an upper cover 911 and a base 912, and the control end of the upper cover 911 has an inclined design from upper right to lower left, allowing the user to place their fingers more comfortably. In addition, in order to improve the convenience of mouse operation in dark environments and attract consumers' attention, the scroll wheel 92 usually has a light-emitting function. As shown in Figure 2A and Figure 2B, the roller 92 has a groove 921, and a rotating shaft 922 protrudes from the bottom surface of the groove 921; 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, causing the roller 92 to produce a glowing 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 and affect 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, causing the brightness of the roller 92 to change, or even causing light leakage. 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 illuminate the area below the rotating shaft 922, so that the local area of the roller 92 will be dark. When the light-emitting module 93 is disposed below the rotating shaft 922 (as shown in FIG. 2B ), the rotating shaft 922 blocks the light emitted by the light-emitting unit 932 , causing the brightness of the roller 92 to decrease. In addition, as shown in the designs of FIG. 2A and FIG. 2B , the circuit board 931 of the light-emitting module 93 needs to be inserted into the groove 921 of the roller 92 , which will increase the difficulty of assembly. Furthermore, as shown in the designs of FIGS. 2A and 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 electrostatic discharge (ESD). The chance of destruction is greatly increased.

Therefore, how to improve the above problems has become the focus of relevant people in this field.
