Description

mouse

The present invention relates to a mouse, in particular to a mouse that can improve the operating feel and reduce the assembly gap.

With the advancement and development of technology, computers have been widely used in everyone's daily life. In terms of current personal computer usage habits, the mouse is one of the indispensable input devices. Generally speaking, the scroll wheel of the mouse produces a sense of paragraph when scrolling, so as to increase the user's operating feel. In addition, the scroll wheel of the mouse will trigger a switch when pressed down to perform input functions. In order to realize the requirements of scrolling and up and down movement of the scroll wheel at the same time, the scroll wheel of the conventional mouse needs to be assembled with many components, and the mechanism design is relatively complicated. Since there are many gaps between the components after assembly, when the roller rolls, some of the components will be driven by the roller and collide with the surrounding structure, thereby affecting the operating feel and generating noise.

One of the objectives of the present invention is to provide a mouse that can improve the operating feel and reduce the assembly gap, so as to solve the above-mentioned problems.

According to an embodiment, the mouse of the present invention includes a base, a micro switch, a scroll wheel, a shaft member, an elastic member, and an arc surface. The base has a supporting part. The micro switch is arranged on the base and opposite to the supporting part. The roller has an accommodating space and a through hole, and the accommodating space is surrounded by a plurality of protrusions. The shaft has a free end, an accommodating groove and a coupling end, wherein the accommodating groove is located between the free end and the coupling end. The free end is arranged relative to the micro switch, the coupling end passes through the through hole to be coupled with the support part, and the accommodating groove is located in the accommodating space. The elastic piece is arranged in the accommodating groove. The arc surface body is arranged on the elastic member and abuts between two adjacent protrusions among the plurality of protrusions.

In summary, in the present invention, the roller is sleeved on the shaft, so as to realize the requirements of rolling and up and down movement of the roller at the same time. Since the coupling end of the shaft is combined with the supporting part, when the roller rolls, the shaft will be restricted by the supporting part and will not roll. In addition, when the scroll wheel is rolling, the arc surface will be pushed by the protrusion of the scroll wheel to produce a sense of paragraph. When the roller is pressed, the joint end of the shaft will rotate with the supporting part as a fulcrum, so that the free end of the shaft triggers the micro switch to perform the input function. In the present invention, the elastic element is arranged in the accommodating groove of the shaft element, the roller is sleeved on the shaft element, and the coupling end of the shaft element is combined with the supporting part to complete the assembly. Thereby, the present invention can effectively reduce the assembly gap, so as to avoid noise when the roller is rolling. In addition, because the assembly gap is reduced, the roller is less likely to shake when rolling. Thereby, the present invention can effectively improve the operating feel.

The advantages and spirit of the present invention can be further understood from the following detailed description of the invention and the accompanying drawings.

In this embodiment, the mouse 1 may further include a grating structure 26, wherein the grating structure 26 may be connected to the side wall of the wheel frame 14a (that is, the grating structure 26 may extend outward from the side wall of the wheel frame 14a). At this time, the through hole 142 penetrates the center of the grating structure 26.

The shaft 16 has a free end 160, a receiving groove 162 and a connecting end 164, wherein the receiving groove 162 is located between the free end 160 and the connecting end 164. The coupling end 164 of the shaft 16 can pass through the through hole 142 of the roller 14 to be coupled with the supporting portion 100 of the base 10. When the roller 14 is sleeved on the shaft 16, the accommodating groove of the shaft 16 162 is located in the accommodating space 140 of the roller 14.

As shown in FIG. 5, the connecting member 22 has a special-shaped hole 220, and the shape of the connecting end 164 of the shaft 16 corresponds to the shape of the special-shaped hole 220. In this embodiment, the irregular hole 220 may be a square hole, and the coupling end 164 of the shaft 16 may be a square, but it is not limited thereto. The shape of the joint end 164 of the special-shaped hole 220 and the shaft 16 can be determined according to actual applications. Therefore, the user can set the coupling end 164 of the shaft 16 in the special-shaped hole 220 of the coupling 22, and set the coupling 22 on the support portion 100 of the base 10, so that the coupling end 164 of the shaft 16 passes through the coupling 22 is combined with the supporting part 100 of the base 10. At this time, the free end 160 of the shaft 16 is set relative to the micro switch 12 and the auxiliary supporting portion 102 of the base 10. When the roller 14 is pressed, the joint end 164 of the shaft 16 will rotate with the supporting portion 100 as a fulcrum, so that the free end 160 of the shaft 16 triggers the micro switch 12 to perform the input function. In addition, when the roller 14 is pressed, the auxiliary support portion 102 can support the free end 160 of the shaft 16 to prevent the shaft 16 from rotating excessively.

As shown in FIG. 7, the elastic member 18 is disposed in the receiving groove 162 of the shaft member 16. In this embodiment, the elastic member 18 can be a spring, but it is not limited to this. In addition, the arcuate body 20 is disposed on the elastic member 18. When the roller 14 is sleeved on the shaft 16, the arcuate body 20 abuts between two adjacent protrusions 144 of the plurality of protrusions 144 and compresses the elastic member 18. In this embodiment, the arcuate body 20 can be an object with an arcuate surface, including but not limited to a sphere, a roller, or an arc slider with a smooth surface.

When assembling the above-mentioned components, the assembler can first set the elastic member 18 in the receiving groove 162 of the shaft member 16. Then, the assembler can set the arc body 20 on the elastic member 18 and set the roller 14 on the accommodating groove 162 of the shaft member 16. At this time, the elastic member 18 is compressed by the arcuate body 20 to push the arcuate body 20 toward the protrusion 144 of the roller 14, and then confine the arcuate body 20 between two adjacent protrusions 144. Then, the assembler can insert the coupling end 164 of the shaft 16 into the special-shaped hole 220 of the coupling 22. At this time, the coupling member 22 abuts against the grating structure 26. The coupling end 164 of the shaft 16 and the special-shaped hole 220 of the coupling 22 can be tightly fitted and fixed. Thereby, the shaft 16 will not fall off from the roller 14. Then, the assembler can combine the connecting member 22 with the supporting part 100 of the base 10 to complete the assembly. It should be noted that the assembler can first install the roller 14, the shaft 16, the elastic member 18, The arcuate body 20 and the connecting member 22 are assembled into a roller module, and then the connecting member 22 is combined with the supporting part 100 of the base 10. In this way, the assembly efficiency can be effectively improved.

As shown in FIGS. 2 and 3, the mouse 1 may further include an optical transmitter 28 and an optical receiver 30. When the roller 14 is assembled to the base 10 in the above manner, the grating structure 26 of the roller 14 is located between the light emitter 28 and the light receiver 30. Therefore, when the scroll wheel is rolling, the grating structure 26, the light transmitter 28, and the light receiver 30 can cooperate with each other to perform the corresponding scrolling function. Since the coupling end 164 of the shaft 16 is coupled with the supporting portion 100 of the base 10 through the coupling 22, when the roller 14 rolls, the shaft 16 is restricted by the supporting portion 100 and does not roll. In addition, when the roller 14 rolls, the arcuate body 20 is pushed by the protrusion 144 of the roller 14 to produce a sense of paragraph.
