Description

Roller module

Technical Field

The present disclosure relates to a wheel module, and more particularly, to a wheel module for a mouse.

Background

The mouse is used to control a cursor on a computer screen and thereby operate the computer. In addition to the left and right buttons, the mouse wheel is the most commonly used button by the average user, for example: the rotary roller is used for browsing the web page or moving a cursor, or the roller is pressed to output a middle key signal, or different functional modes are switched.

In order to make the mouse more comfortable for the user to operate, many ergonomic designs are widely used for the housing of the mouse, such as the mouse 9 shown in fig. 1, which includes: the housing 91 and the roller 92, the housing 91 includes a top cover 911 and a base 912, and the control end of the top cover 911 is inclined from top right to bottom left, so that the fingers of the user can be more comfortably placed. In addition, in order to improve the convenience of operating the mouse in a dark environment and to attract the attention of the consumer, the roller 92 usually has a light-emitting function. As shown in fig. 2A and 2B, the roller 92 has a groove 921, and a rotating shaft 922 protrudes from the bottom of the groove; the light emitting module 93 includes: a circuit board 931 and a light emitting unit 932, wherein the light emitting unit 932 is disposed in the groove 921 and is configured to emit light toward the roller 92, so that the roller 92 generates a luminous visual effect. The middle key switch module 94 is disposed below the rotating shaft 922.

In the prior art, when the light emitting module 93 is disposed above the rotation shaft 922 (as shown in fig. 2A), the light emitting module 93 is too close to the top cover 911, which affects the tilt design of the top cover 911. When the roller 92 is pressed, the light-emitting module 93 does not descend along with the roller 92, so that the light-emitting unit 932 is too close to or contacts the inner circumferential surface of the groove 921, and the brightness of the roller 92 is changed, or even light leakage occurs. If the light emitting unit 932 is too close to or contacts the inner circumferential surface of the groove 921, a rubber bump (not shown) is additionally disposed on the circuit board 931 close to the light emitting unit 932, so as to prevent Electrostatic Discharge (ESD) from damaging the light emitting unit 932.

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, resulting in a decrease in brightness of the roller 92 when emitting light.

Therefore, the technical problem to be solved by the present invention is how to provide a roller module, so that the relative arrangement of the rotating shaft and the light emitting module does not affect the inclined design of the control end of the mouse, and how to prevent the rotating shaft from shielding the light emitted by the light emitting module.

The control end of the top cover 101 has a roller through hole 1011, and the roller module 20 is partially exposed and protruded from the roller through hole 1011. On the other hand, the second support 1022 is located on the same side as the key switch module 40. In the present embodiment, the light emitting module 30 includes: the circuit board 301 and the light emitting unit 302 disposed at one end of the circuit board 301, wherein one end of the circuit board 301 opposite to the light emitting unit 302 is fixed on the second support 1022 in a locking manner, and one end of the circuit board 301 having the light emitting unit 302 is disposed in the roller module 20. The light emitting unit 302 may be: a light emitting diode unit, an organic light emitting diode unit, a quantum dot light emitting diode unit, or an electroluminescent unit.

The electrical connector 70 is electrically connected to the main circuit board 60, and may be a usb interface, such as: USB 2.0, USB 3.0, or USB 3.1, and is used to output a key signal, a middle key signal, or a wheel signal to an electronic device or a computer (not shown in the figure, such as a notebook computer or a personal computer) connected to the mouse 1. Although the embodiment of the present invention is only provided for connecting the electronic device or the computer with the wired electrical connector 70, in practical applications, the electrical connector 70 may be replaced by the existing wireless connection module, and the embodiment of the present invention is not limited thereto.

When the user dials the roller module 20, the roller module 20 will drive the encoder 50, and the encoder 50 can sense the rotation distance, the rotation direction and the rotation speed of the roller module 20 to output a corresponding roller signal; when the user presses the wheel module 20, the wheel module 20 moves downward along the slide hole 10211 and presses the middle key switch module 40 to output a corresponding middle key signal.

Referring to fig. 4A and 4B, fig. 4A is an exploded perspective view of a roller module according to an embodiment of the present invention; fig. 4B is an exploded perspective view of another perspective of the roller module provided by the present invention. The roller module 20 includes: a roller 21, a rim 22, a rotating member 23, a circular shade 24 and an annular shade 25.

The roller 21 includes: a groove 211 and an annular groove 214. The bottom surface of the recess 211 has a through shaft hole 212 and one or more positioning holes 213 disposed around the shaft hole 212. The annular groove 214 is disposed on the outer circumferential surface of the roller 21 and is for the rim 22 to be sleeved therein. In the present embodiment, the rim 22 can be made of a light-tight elastic material, so as to increase the friction force on the surface of the roller 21 and provide a good pressing feeling.

The rotation member 23 includes: a turntable 231, a first rotation shaft 23111, a second rotation shaft 23121 and one or more positioning protrusions 23122. The turntable 231 has a first surface 2311 and a second surface 2312 opposite to each other, the first rotating shaft 23111 is disposed at the axial center position of the first surface 2311, the second rotating shaft 23121 is disposed at the axial center position of the second surface 2312, the positioning protrusions 23122 are disposed on the second surface 2312 and surround the second rotating shaft 23121, and the disposition positions, shapes or number of the positioning protrusions 23122 correspond to the disposition positions, shapes or number of the positioning holes 213 at the bottom surface of the groove 211. When the rotating member 23 is installed in the groove 211, the second surface 2312 of the rotating disc 231 faces the bottom surface of the groove 211, the second rotating shaft 23121 and the positioning protrusion 23122 are respectively inserted through the shaft hole 212 and the positioning hole 213, and the rotating disc 231 is fixed on the bottom surface of the groove 211 by the combination of the positioning protrusion 23122 and the positioning hole 213. Although the embodiment of assembling the rotating member 23 and the roller 21 by combining the protrusion 23122 and the positioning hole 213 is only proposed in the present embodiment, in practical applications, the positioning protrusion 23122 may be disposed on the bottom surface of the groove 211, and the positioning hole 213 may be disposed on the turntable 231. Alternatively, the bottom surface of the recess 211 does not need to be provided with the positioning hole 213, and the second surface 2312 of the turntable 231 does not need to be provided with the corresponding positioning protrusion 23122, but the turntable 231 is fixed on the bottom surface of the recess 211 by glue adhesion or clamping.

The second rotating shaft 23121 has a polygonal shaft portion 231211 that corresponds to the polygonal shaft hole 501 (shown in fig. 3) of the encoder 50. When the roller 21 is installed, the second rotating shaft 23121 sequentially penetrates through the sliding hole 10211 of the supporting member 1021 and the polygonal shaft hole 501 of the encoder 50, and the polygonal shaft portion 231211 penetrates through and is fixed in the polygonal shaft hole 501, so that when the roller module 20 rotates, the encoder 50 can be driven to rotate by the rotating member 23.

With reference to fig. 4A and 4B, the rotating member 23 may be integrally formed and made of a transparent material for light to penetrate. In another possible embodiment, the first rotating shaft 23111 and the second rotating shaft 23121 are integrally formed and then penetrate through the axis of the rotating disc 231, and the first rotating shaft 23111 and the second rotating shaft 23121 are made of transparent materials; the turntable 231 is made of a non-light-tight material. In another possible embodiment, the first rotating shaft 23111 is made of a transparent material and is fixed to the first surface 2311 of the rotating disc 231 at the axial center; the turntable 231 is made of a non-light-tight material.

The circular light shielding member 24 is used for covering the other surface corresponding to the groove 211 and has a central opening 241 corresponding to the second rotating shaft 23121; the ring-type light shielding member 25 is disposed around the recess 211 and is used to partially cover the edge of the recess 211.

Referring to fig. 5, fig. 5 is a schematic view illustrating the light emission of the roller module. One end of the circuit board 301 is partially disposed in the recess 211, and the light emitting unit 302 of the light emitting module 30 is located below the first rotation axis 23111. The light emitting unit 302 is used for emitting light L, and then the light L can pass through the first rotating shaft 23111 and be transmitted to the roller 21. The circular light-shielding member 24 and the annular light-shielding member 25 are used for shielding two opposite sides of the roller 21 to prevent or reduce the light L from escaping from the two opposite sides of the roller 21. After the light L is transmitted to the roller 21, the light L can be transmitted out from the area not shielded by the circular light shielding member 24, the annular light shielding member 25 and the rim 22, so that the roller module 20 generates a luminous visual effect. In order to improve the light emitting efficiency of the roller module 20, in a possible embodiment, a light diffusing agent or titanium dioxide may be added during the manufacturing of the roller 21, so as to improve the brightness and uniformity of the roller 21 during light emitting. In another possible embodiment, the rim 22 can be made of a transparent elastic material, so that the light L can be transmitted to the roller 21 and then can be transmitted out from the position where the rim 22 is disposed, thereby increasing the range of the roller 21 emitting light.

Compared with the mouse roller structure in the prior art, the rotating shaft of the roller module provided by the invention has light penetrability, and when the light-emitting module is arranged below the rotating shaft, light generated by the light-emitting module can penetrate through the rotating shaft with light penetrability and then is transmitted to the roller, so that the light-emitting brightness and the light-emitting uniformity of the roller module can be maintained. The light-emitting module is arranged below the rotating shaft, so that the inclined design of the mouse control end is not influenced. In addition, the light-emitting unit of the light-emitting module can be far away from the inner circumferential surface of the roller groove, so that the light-emitting unit can be effectively prevented from being damaged by electrostatic discharge; therefore, the present invention is an invention with great industrial value.

The invention may be modified in various ways by anyone skilled in the art without however departing from the scope of the appended claims.
