The roller module on the top surface of the mouse is mainly used for controlling the rolling of a computer screen picture, and the rotating speed of a user operating the roller by fingers is directly related to the rolling speed of the screen picture and the picture range which can be browsed by the user in unit time.
The rolling speed of the roller is generally detected by an encoder.

Detailed Description
The foregoing and other features, aspects and advantages of the present invention will become more apparent from the following detailed description of a preferred embodiment, which proceeds with reference to the accompanying drawings. The directional terms mentioned in the following embodiments are, for example: upper, lower, left, right, front or rear, etc., are merely references to the directions of the attached drawings. Thus, the directional terminology is used for purposes of illustration and is not intended to be limiting of the invention.
Referring to fig. 1 to 4, fig. 1 is a schematic view of an external appearance of a mouse 1 according to an embodiment of the present invention, fig. 2 is an exploded view of elements of a mouse wheel device 10 according to a first embodiment of the present invention, and fig. 3 and 4 are schematic views of the mouse wheel device 10 according to the first embodiment of the present invention at different viewing angles. The mouse wheel device 10 of the mouse 1 may be partially exposed from the opening of the housing 2 for touch operation by a user. The mouse wheel device 10 may mainly include a base 12, a wheel module 14, a shading element 16, and a light detecting module 18. The kettle-shaped supporting piece 20 of the base 12 is open at the top side and is used for bearing the roller module 14; the support 20 is pivotally connected to the front bracket 12a and the rear bracket 12b of the base 12 along the longitudinal direction Y, so that the roller module 14 and the support 20 can rotate laterally in the yaw direction R. The base 12 may include a circuit board (not shown), or at least a portion of the surface of the base 12 may have electrical circuitry.
The roller module 14 may be formed by combining a wheel shaft 22 with a hollow roller member 24. The axle 22 may include a tread 26, a pivot 28, and a plurality of ribs 30. A rib 30 may be coupled to the pivot shaft 28 and disposed within the tread 26. The pivot 28 is rotatably disposed on the support 20 along an axis D, and the pivot 28 is a cylindrical bearing including a ratchet 28a in this embodiment, wherein the pivot 28 is connected to a plurality of ribs 30, and extends to the outside of the axle 22 along the axis D to connect with the ratchet 28a, and the ratchet 28a can cooperate with additional adjustment elements for switching the rolling mode and the operating feel of the roller module 14. For example, in some embodiments, the wheel surface 26 portion of the wheel axle 22 may be formed of a metallic material that is capable of high-speed inertial rotation when the mouse wheel assembly 10 is operated, providing a large scroll through range for applications such as screen scrolling. The wheel member 24 is disposed on the periphery of the wheel surface 26 for the user to operate the mouse wheel device 10.
The light detecting module 18 may include a light emitter 36 and a light receiver 38 disposed on a first side and a second side of the roller module 14 opposite to each other. The arrangement of the optical transmitter 36 and the optical receiver 38 is not limited to that shown in fig. 2 to 4, meaning that the positions of the optical transmitter 36 and the optical receiver 38 may be interchanged. The support 20 may have a hole 40. The opening direction of the broken hole 40 is not limited to that shown in fig. 2 to 4. The light signal S projected by the light emitter 36 passes through the hole 40 of the supporting member 20, the roller module 14 and the shading element 16, and is received by the light receiver 38. As the roller module 14 rotates, the light signal S is intermittently stopped by the light shielding region 32 or passes through the light transmitting region 34. The light receiver 38 can obtain the behavior information to be expressed by the user operating the roller module 14 according to the receiving condition, the receiving frequency and the receiving time of the optical signal S.
The light shielding element 16 is used for providing a grating structure, and may be composed of a plurality of light shielding regions 32 and a plurality of light transmitting regions 34 arranged alternately on the wheel shaft 22 or the roller member 24 around the axis direction D. Generally, the light shielding region 32 may be perpendicular to the pivot axis 28. The shading element 16 may further comprise an outer annular region 42 and an inner annular region 44. The outer annular region 42 may be connected to the outer end of each of the light shielding regions 32, and the inner annular region 44 may be connected to the inner end of each of the light shielding regions 32. In this embodiment, the light shielding element 16 may be an independent opaque sheet, that is, the light shielding region 32, the outer ring region 42 and the inner ring region 44 are made of opaque materials, and the light transmitting region 34 is a hollow region between the light shielding region 32, the outer ring region 42 and the inner ring region 44. The shading element 16 will be fixed to the wheel axle 22 side. Specifically, the outer ring region 42 of the light shielding element 16 may be attached to the side edge of the tread 26 and/or the connection between the outer end side edge of each spoke 30 and the tread 26; a portion of the light shielding regions 32 of the light shielding element 16 are attached to each of the ribs 30, such that the light shielding regions 32 and the light transmitting regions 34 can be alternately disposed on the axle 22 or the roller member 24 around the axial direction D; the inner ring area 44 may be attached to the side edge of the pivot shaft 28 and/or the connection between the inner end edge of each rib 30 and the pivot shaft 28. The ribs 30 do not have to have a light-transmitting property, and the thickness of each rib 30 is preferably equal to or smaller than the width of each light-shielding region 32 of the light-shielding element 16, so that the transmission of the optical signal S is simply controlled by the light-shielding regions 32 and the light-transmitting regions 34 of the light-shielding element 16, and is not interfered by the ribs 30.
In the first embodiment, the light shielding element 16 may be selectively attached to one side of the wheel shaft 22 and/or the roller member 24. If the light shielding element 16 is attached to the axle 22, the light shielding element 16 can be attached to the edge of the spoke rib 30 by at least one of the light shielding region 32, the outer ring region 42 or the inner ring region 44, and the light signal S output by the light emitter 36 can pass through the gap between the light transmitting region 34 of the light shielding element 16 and the spoke rib 30 and be transmitted to the light receiver 38; the material of the roller member 24 is not limited. If the light shielding element 16 is attached to the roller element 24, the light shielding element 16 may be attached to the side surface of the roller element 24 by at least one of the light shielding region 32, the outer ring region 42 or the inner ring region 44, and the roller element 24 is preferably made of transparent material; in this embodiment, the light shielding element 16 may be directly formed on the side or inside of the roller element 24, and the variation thereof may be determined according to the design requirement.
The number of ribs 30 is not limited to the embodiment of fig. 2-4, as long as it is sufficient to stably support the tread 26 on the pivot 28 in accordance with the design requirements of the present invention. The number of the light shielding regions 32 and the light transmitting regions 34 can be designed according to the sampling frequency or the identification accuracy of the light detection module 18. The light shielding regions 32 and the light transmitting regions 34 should have the same number, and the number of light shielding regions 32 and light transmitting regions 34 may be greater than or equal to the number of ribs 30. However, the roller with the grating structure is usually manufactured by opening a mold, so that the cost is expensive and the number of gratings is difficult to adjust. Since the number of ribs 30 of the axle 22 is limited by the molding technique, the number of optical signals that affect the rolling operation detected by the optical detection module 18 by one rotation of the roller module 14 and the axle 22 is limited. The significance of the present embodiment is that the rib 30 is not used as the grating structure, and when the number of times of the light signal receivable by each rotation is not limited by the rib 30, the roller module 14 and the wheel axle 22 with higher manufacturing cost can be shared in different functional types of mouse products, and the benefit of sharing the wheel axle 22 and customizing the grating structure can be realized by adjusting and modifying the light shielding element 16 with low cost.
Referring to fig. 5 to 7, fig. 5 to 7 are schematic views of the light shielding element 16 combined with the wheel axle 22 according to various embodiments of the present invention. In the embodiment shown in fig. 5, the light shielding element 16 may have a light shielding region 32, a light transmitting region 34, an outer ring region 42, and an inner ring region 44; the outer ring region 42 is disposed on the side of the tread 26 of the axle 22, the inner ring region 44 is disposed on the side of the pivot 28 of the axle 22, and the light shielding region 32 is connected between the outer ring region 42 and the inner ring region 44 and can be used to shield the rib 30. In the embodiment shown in fig. 6, the light shielding element 16 may have only the light shielding region 32, the light transmitting region 34, and the outer ring region 42; the outer annular region 42 is disposed on the side of the tread 26, and the light shielding region 32 extends inwardly from the outer annular region 42, wherein the light shielding region 32 is capable of shielding the rib 30, and a portion of the light shielding region 32 is not capable of shielding the rib 30. In the embodiment shown in fig. 7, the light shielding element 16 may have only the light shielding region 32, the light transmitting region 34 and the inner ring region 44; the inner ring region 44 is disposed on the side of the pivot 28, the light shielding region 32 extends outwardly from the inner ring region 44, the light shielding region 32 is capable of shielding the rib 30, and a portion of the light shielding region 32 is not capable of shielding the rib 30.

In the second embodiment, elements having the same numbers as those in the first embodiment have the same structure and function, and the description thereof will not be repeated. The difference between the second embodiment and the first embodiment is that the mouse wheel device 10' further includes a light emitting element 50, and the light emitting element 50 is electrically connected to a circuit board (not shown) on the base 12; in addition, the wheel module 14 'of the mouse wheel device 10' may include a wheel shaft 52 and a transparent wheel member 54.

In addition, when the axle 52 is made of transparent material, the light shielding region 32 of the light shielding element 16 may be a light shielding ink layer formed on the light guiding surface 58, the wall surface 60 or the inside of the axle 52; alternatively, the light shielding region 32 may be a laser-etched modified layer that is opaque and formed inside the light guiding surface 58, the wall surface 60 or the axle 52. Accordingly, the light shielding region 32 of the light shielding element 16 may also be a light shielding ink layer or an opaque laser etched modified layer formed by partially processing the transparent roller element 54.
As shown in fig. 8 to 11, the light shielding element 16 of the second embodiment can also have various modifications correspondingly. When the light shielding element 16 includes the light shielding region 32, the light transmitting region 34, the outer ring region 42 and the inner ring region 44 are respectively disposed at the outer edge and the inner edge of the side surface of the axle 52 or the transparent roller 54, the light shielding region 32 is connected between the outer ring region 42 and the inner ring region 44, and the light transmitting region 34 is a gap between adjacent light shielding regions 32. When the light shielding element 16 only includes the light shielding region 32, the light transmitting region 34 and the outer ring region 42, the outer ring region 42 is disposed at the outer edge of the side surface of the axle 52 or the transparent roller member 54, the light shielding region 32 extends inward from the outer ring region 42, and the light transmitting region 34 is a hollow region between adjacent light shielding regions 32. When the light shielding element 16 only includes the light shielding region 32, the light transmitting region 34 and the inner ring region 44, the inner ring region 44 is disposed at the inner edge of the side surface of the axle 52 or the transparent roller member 54, the light shielding region 32 extends outwards from the inner ring region 44, and the light transmitting region 34 is a gap between adjacent light shielding regions 32. When the light shielding element 16 only includes the light shielding region 32 and the light transmitting region 34, the light shielding region 32 is disposed on the side surface of the axle 52 or the transparent roller member 54.
Referring to fig. 15 to 20, fig. 15 to 17 are schematic views of the light shielding element 16 combined with the axle 52 according to various embodiments of the present invention, and fig. 18 to 20 are schematic views of the light shielding element 16 combined with the hollow transparent roller 54 according to various embodiments of the present invention. As shown in fig. 15, the light shielding region 32 of the light shielding element 16 can be disposed on the wall 60 of the axle 52 in the form of a light shielding ink layer or a light-proof laser engraving modification layer, and the light shielding region 32 is perpendicular to the pivot 56. As shown in fig. 16, the light shielding region 32 of the light shielding element 16 can be disposed on the light guiding surface 58 of the axle 52 in a light shielding ink layer or a light-proof laser engraving modification layer, and the light shielding region 32 is not perpendicular to the pivot 56. As shown in fig. 17, the light shielding region 32 of the light shielding element 16 can be disposed inside the axle 52 in a light-tight laser engraving modification, for example, between the light guiding surface 58 and the wall surface 60, and the light shielding region 32 can be optionally perpendicular or non-perpendicular to the pivot 56.
As shown in fig. 18, the light shielding region 32 of the light shielding element 16 may be disposed adjacent to the wall 60 of the transparent roller member 54 or on a first side facing the light emitter 36 in the form of a light shielding ink layer or an opaque laser engraving layer, where the light shielding region 32 is perpendicular to the pivot 56. As shown in fig. 19, the light shielding region 32 of the light shielding element 16 may be disposed on a second side of the transparent roller member 54 facing the light receiver 38 or adjacent to the light guiding surface 58 in a manner of a light shielding ink layer or a light-tight laser engraving modification layer, wherein the first side is opposite to the second side, and the light shielding region 32 is perpendicular to the pivot 56. As shown in fig. 20, the light shielding region 32 of the light shielding element 16 can be disposed inside the transparent roller member 54 in a manner of opaque laser engraving modification layer, that is, between the first side and the second side, where the light shielding region 32 can be optionally perpendicular or non-perpendicular to the pivot 56. In the above embodiments, the light-transmitting region 34 of the light-shielding element 16 is a region between adjacent light-shielding regions 32.
Referring to fig. 21, fig. 21 is a schematic diagram illustrating a portion of a mouse wheel device 10' according to a second embodiment of the invention. The wall 60 of the axle 52 is perpendicular to the pivot 56 and thus serves to conceal one side of the hollow extent of the transparent roller member 54. The light guiding surface 58 of the axle 52 is accommodated in the hollow area of the transparent roller member 54, so that the illumination light outputted from the light emitting element 50 can generate a light emitting effect on the transparent roller member 54 through the reflection of the light guiding surface 58. In the second embodiment, the light guiding surface 58 is designed as a cone structure, and the height, width, and inclination angle of the cone structure are not limited to the configuration shown in fig. 21, and may be determined according to the design requirements. The shape of the light guiding surface 58 is not limited to the conical structure shown in fig. 21, as long as the cross-sectional shape of the light guiding surface 58 capable of uniformly reflecting the illumination light to the top surface of the transparent roller member 54 meets the design requirement of the light guiding surface 58 of the present invention. In general, the axle 52 and the transparent roller 54 lacking the hollow area cannot be used as a grating structure. In the present embodiment, when the light shielding element 16 is disposed on the wall 60 of the axle 52, the light emitter 36 and the wall 60 of the light detecting module 18 are disposed on the same side (first side) of the roller module 14, and the light receiver 38 and the light guiding surface 58 are also disposed on the same side (second side) of the roller module 14. The light signal S projected by the light emitter 36 sequentially passes through the wall 60, the light guide surface 58 and the light shielding element 16 of the axle 52, or sequentially passes through the wall 60, the light shielding element 16 and the light guide surface 58, or sequentially passes through the light shielding element 16, the wall 60 and the light guide surface 58, and is received by the light receiver 38. That is, the light signal S enters from the wall 60 and exits from the light guiding surface 58, so that the wheel axle 52 lacking the hollow area and having the light guiding surface 58 which is not easy to penetrate can also be combined with the light shielding element 16 to serve as a grating structure.
Referring to fig. 22 to 24, fig. 22 is an exploded view of a mouse wheel device 10 "according to a third embodiment of the present invention, and fig. 23 and 24 are schematic views of the mouse wheel device 10" according to the third embodiment of the present invention at different viewing angles. In the third embodiment, elements having the same numbers as those in the previous embodiment have the same structure and function, and the description thereof will not be repeated. The difference between the third embodiment and the previous embodiments is that the roller module 14 "of the mouse roller device 10" may include a first half axle 62, a second half axle 64, and a hollow roller member 66. The first half axle 62 and the second half axle 64 are rotatably disposed on the support 20. The first half axle 62 and the second half axle 64 have a first light guiding surface 68 and a second light guiding surface 70, respectively. The roller member 66 is made of transparent material and is disposed between the first half axle 62 and the second half axle 64. The light-emitting element 72 of the mouse wheel device 10″ is selectively extended into the wheel member 66 by at least one of the first half axle 62 and the second half axle 64. At least a portion of the illumination light outputted from the light emitting element 72 can be reflected by the first light guiding surface 68 and the second light guiding surface 70 and pass through the roller member 66, so that the mouse roller device 10″ has a light emitting function.
In addition, the supporting member 20 may further have a hole 74, and the optical signal S output by the optical transmitter 36 is received by the optical receiver 38 through the hole 74. Furthermore, the first half axle 62 may have a first wheel wall 76 perpendicular to the axial direction D and the second half axle 64 may have a second wheel wall 78 perpendicular to the axial direction D. The first light guiding surface 68 may be an inner surface of the first wheel wall 76, and the second light guiding surface 70 may be an inner surface of the second wheel wall 78. The first wheel wall 76 may further extend beyond a pivot 80, and a ratchet 82 is disposed on the pivot 80. The second wheel wall 78 may then extend out of a hub 86 having a through hole 84. The first wheel wall 76 and the second wheel wall 78 are used to clamp two sides of the roller member 66, respectively, and are rotatably disposed on the support member 20 by means of a pivot 80 and/or a shaft frame 86. The ratchet 82 may be provided with additional adjustment elements for switching the rolling mode and the operating feel of the roller module 14. The light emitting element 72 may enter the hollow region of the interior of the roller member 66 via the through hole 84.
The shading elements 16 of the mouse wheel device 10 "may be formed directly on the wheel face, side and/or inside of the transparent wheel member 66; as shown in fig. 22 to 24, the roller member 66 has the light shielding element 16 on both the wheel surface and the side surface. The shading area 32 of the shading element 16 can be formed by shading ink layer or opaque laser engraving modification layer, and is formed on the roller element 66 made of transparent material, so that a part of the area of the transparent roller element 66 can achieve the shading purpose. The light-transmitting region 34 of the light-shielding element 16 is the other region of the transparent roller member 66 that does not belong to the light-shielding region 32.
Alternatively, the roller module 14 "may further include a wheel cover 88 disposed over a ring groove 90 on the tread of the roller member 66. The wheel cover 88 may have elasticity, and may cooperate with the axial clamping force of the first half wheel axle 62 and the second half wheel axle 64 on the roller member 66 to provide a tightening force on the roller member 66 in the radial direction; alternatively, the same common roller member 66 can be provided with different user finger feel or friction differences in combination with different microstructures or surface treatments on the wheel cover 88. Preferably, the width W1 of the wheel cover 88 is smaller than the width W2 of the roller member 66, i.e., the roller member 66 partially covers the wheel cover 88 with the ring groove 90 such that the outer surface of the wheel cover 88 is aligned with the outer edge of the roller member 66. If the roller module 14 "mounts the wheel cover 88 in the ring groove 90 of the roller member 66, the light shielding element 16 of the mouse roller device 10" may be formed not only directly on the wheel surface, side surface and/or inside the roller member 66, but also in the ring groove 90; in this embodiment, the light shielding region 32 of the light shielding element 16 may be a light shielding ink layer or an opaque laser etched modified layer.
In the third embodiment, the arrangement angle of the light emitting element 72 is not limited to the arrangement shown in fig. 22 to 24, and the inclination angle thereof can be adjusted according to the position of the mouse wheel device 10″ on the housing 2 of the mouse 1. Referring to fig. 23 and 25, fig. 25 is a schematic diagram of a mouse wheel device 10″ according to a third embodiment of the present invention. In the embodiment shown in fig. 23, the planar normal vector of the upper surface of the light emitting element 72 is directed straight upward, meaning that the illumination light provided by the light emitting element 72 is directed directly above the roller member 66. In the embodiment shown in fig. 25, the plane normal vector of the upper surface of the light emitting element 72 is inclined at an angle (toward the left of the drawing), so that the mouse wheel device 10″ is exposed from the inclined opening of the front half of the housing 2, in other words, the plane normal vector of the upper surface (light emitting surface) of the light emitting element 72 is perpendicular to the inclined opening of the housing 2, so that the illumination light provided by the light emitting element 72 preferably passes through the inclined opening of the housing 2 directly via the roller member 66 or the side edge thereof, and the area of the roller member 66 protruding out of the housing 2 can provide better light emitting effect. It should be noted that the inclination direction and the angle of the light emitting element 72 are not limited to the embodiment shown in fig. 25, and may be determined according to design requirements. In addition, although not shown, the light shielding element 16 may be a separate opaque sheet attached to one side of the roller member 66 for rotation therewith. In general, the first half axle 62, the second half axle 64 and the roller member 66, which lack the hollow area, cannot be used as a grating structure, and in particular, the hollow axle frame 86 must be used to dispose the light emitting element 72. In this embodiment, the light shielding element 16 is directly formed on the wheel surface, the side surface and/or the inside of the transparent roller element 66, so that the light signal S projected by the light emitter 36 can pass through the transparent roller element 66 with the light shielding element 16 and be received by the light receiver 38, so that the roller module 14″ lacking the hollowed-out area can also be combined with the light shielding element 16 to serve as a grating structure. Furthermore, in addition to the grating structure for shielding the light signal S, the light shielding element 16 may also rotate along with the roller element 66, and intermittently shield the illumination light passing through the roller element 66 through the light shielding region 32 formed on the wheel surface, the side surface and/or the inside of the transparent roller element 66, and simultaneously provide intermittent illumination light effect to the roller element 66.
In summary, the wheel shaft or the wheel member of the mouse wheel device of the present invention is provided with the light shielding element with low cost, so as to form the staggered light shielding area and the light transmitting area for intermittently blocking the detection light path of the light detection module to obtain the rotation information of the wheel module and the input command represented by the rotation information. The shading area and the light transmitting area of the shading element can provide various implementations according to whether the shading area and the light transmitting area are matched with the outer ring area and the inner ring area, and the material and the manufacturing mode of the shading area can be correspondingly changed according to the positions of the shading area and the light transmitting area. Therefore, the shape and position of the shading element can be adaptively modified according to different requirements, so that not only can the customized service of the grating structure with better elasticity be provided, but also the high-cost wheel axle can be used for mice with different function types.
The above detailed description of the preferred embodiments is intended to more clearly describe the features and spirit of the present invention, but is not intended to limit the scope of the present invention by the above disclosed preferred embodiments. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the scope of the invention as defined by the appended claims. The scope of the invention is therefore to be construed in its broadest sense in view of the foregoing description and is instead intended to cover all possible modifications and equivalent arrangements.
