Description

mouse wheel device

technical field

The invention relates to a mouse wheel device, in particular to a mouse wheel device which uses optical technology to read rotation information.

Background technique

The scroll wheel module on the top of the mouse is mainly used to control the scrolling of the computer screen. The rotation speed of the scroll wheel operated by the user with fingers is directly related to the scrolling speed of the screen and the range of pictures that the user can browse per unit time.

The scrolling speed of the scroll wheel is generally detected by an encoder. The most widely used on the mouse is the mechanical encoder. Compared with the grating encoder, the mechanical encoder has a simple structure, easy master control programming and a mechanical scale feel. The mechanical encoder has a turntable. When the mouse wheel rotates to drive the turntable of the mechanical encoder, multiple contacts on the turntable and fixed contacts on the base come into electrical contact with each other, thereby generating intermittent conduction signals.

The grating encoder uses a group of optical transceiver modules to be installed on both sides of the grating structure. When the scroll wheel is rolling, the grating structure blocks and conducts the optical signal, which can be used to detect the rotation speed of the mouse wheel. The external optical code disc linked with the gear or pivot and the roller can be used as a grating structure, so that the optical transceiver module can generate intermittent signals corresponding to the rotation speed of the roller as the optical code disc rotates.

At the same time, the need for the scroll wheel on the top surface of the mouse to be able to emit light brings new challenges to the mouse that uses a grating encoder to detect the rotation speed of the scroll wheel.

Detailed ways

The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the drawings. The directional terms mentioned in the following embodiments, such as: up, down, left, right, front or back, etc., are only directions referring to the attached drawings. Accordingly, the directional terms used are for the purpose of illustration and not for the purpose of limiting the invention.

Please refer to FIGS. 1 to 4. FIG. 1 is a schematic view of the appearance of a mouse 1 according to an embodiment of the present invention. FIG. 2 is an exploded view of components of a mouse wheel device 10 according to a first embodiment of the present invention. A schematic diagram of the mouse wheel device 10 in different viewing angles according to an embodiment.

In this embodiment, the pivot 28 is a cylindrical bearing including a ratchet 28a, wherein the pivot 28 is connected to a plurality of spoke ribs 30, Extending to the outside of the wheel shaft 22 to connect with the ratchet 28a, the ratchet 28a can cooperate with additional adjustment elements for switching the scrolling mode and operation feel of the roller module 14 . For example, in some embodiments, the wheel surface 26 of the wheel shaft 22 can be made of metal material, which can rotate at high speed when the mouse wheel device 10 is operated, and can provide a larger scrolling range in applications such as screen scrolling. The wheel member 24 can be on the periphery of the wheel surface 26 as a contact interface for the user to operate the mouse wheel device 10 .

The light detection module 18 may include a light emitter 36 and a light receiver 38 respectively disposed on a first side and a second side of the roller module 14 opposite to each other. The arrangement of the light emitter 36 and the light receiver 38 is not limited to that shown in FIGS. 2 to 4 , which means that the positions of the light emitter 36 and the light receiver 38 can be interchanged. The support 20 may have perforations 40 . The opening direction of the perforated hole 40 is not limited to that shown in FIGS. 2 to 4 . The light signal S projected by the light transmitter 36 passes through the perforation 40 of the support member 20 , the roller module 14 and the light shielding element 16 , and is received by the light receiver 38 . As the roller module 14 rotates, the optical signal S is intermittently blocked by the light-shielding area 32 or passes through the light-transmitting area 34 . According to whether the optical signal S is received or not, the receiving frequency and the receiving time, the optical receiver 38 can obtain the behavior information that the user intends to express by operating the scroll wheel module 14 .

The light-shielding element 16 is used to provide a grating structure, which can be composed of a plurality of light-shielding regions 32 and multiple light-transmitting regions 34 arranged in an arrangement, and can be alternately arranged on the wheel shaft 22 or the roller member 24 around the axial direction D. Generally speaking, the light shielding area 32 can be perpendicular to the pivot 28 . The light shielding element 16 may further include an outer ring area 42 and an inner ring area 44 . The outer ring area 42 can connect the outer ends of the light-shielding areas 32 , and the inner ring area 44 can connect the inner ends of the light-shielding areas 32 . In this embodiment, the light-shielding element 16 can be an independent opaque sheet, which means that the light-shielding area 32, the outer ring area 42 and the inner ring area 44 are all made of opaque materials, and the light-transmitting area 34 is the light-shielding area 32, The hollow area between the outer ring area 42 and the inner ring area 44 . The shading element 16 will be fixed on one side of the axle 22 . Specifically, the outer ring area 42 of the shading element 16 can be attached to the side edge of the wheel surface 26, and/or the junction of the outer end side edge of each spoke rib 30 and the wheel surface 26; the partial shading area 32 of the shading element 16 is attached On each spoke rib 30, a plurality of light-shielding areas 32 and a plurality of light-transmitting areas 34 can be alternately arranged on the wheel shaft 22 or the roller member 24 around the axial direction D; the inner ring area 44 can be attached to the side edge of the pivot shaft 28 , and/or the junction of the inner edge of each spoke rib 30 and the pivot 28 . The radial ribs 30 do not necessarily have light-transmitting properties. The thickness of each radial rib 30 is preferably equal to or smaller than the width of each light-shielding area 32 of the light-shielding element 16, so that the transmission of the optical signal S is only affected by the light-shielding area 32 of the light-shielding element 16. Controlled with the light-transmitting area 34 without being interfered by the radial ribs 30 .

In the first embodiment, the light-shielding element 16 can be selectively attached to one side of the axle 22 and/or the roller member 24 . If the shading element 16 is attached to the axle 22, the shading element 16 can be attached to the edge of the radial rib 30 with at least one of the shading area 32, the outer ring area 42 or the inner ring area 44, and the optical signal S output by the light transmitter 36 can pass through Through the gap between the light-transmitting area 34 of the light-shielding element 16 and the radial ribs 30 , it is transmitted to the light receiver 38 ; at this time, the material of the roller member 24 is not limited. If the shading element 16 is attached to the roller part 24, the shading element 16 can be attached to the side of the roller part 24 by using at least one of the shading area 32, the outer ring area 42 or the inner ring area 44, and the roller part 24 is preferably made of transparent Material manufacturing; in this embodiment, the shading element 16 can be directly formed on the side or inside of the roller member 24, and the change can be determined according to the design requirements.

The number of spoke ribs 30 is not limited to the embodiments shown in FIGS. 2 to 4 , as long as it is sufficient to stably support the wheel surface 26 on the pivot 28 , it meets the design requirements of the present invention. The number of the light-shielding area 32 and the light-transmitting area 34 can be designed according to the requirements of the sampling frequency and recognition accuracy of the light detection module 18 . The number of light-shielding regions 32 and light-transmitting regions 34 should be the same, and the number of light-shielding regions 32 and light-transmitting regions 34 may be greater than or equal to the number of radial ribs 30 . However, a roller with a grating structure usually requires a mold to be manufactured, so the cost is relatively expensive and it is difficult to adjust the number of gratings. Since the manufacturing cost and yield of the spoke ribs 30 of the wheel shaft 22 are often limited by the molding technology, it will affect the rolling operation that the light detection module 18 can detect when the wheel module 14 and the wheel shaft 22 make one revolution. the number of optical signals. The significance of not using the spoke ribs 30 as the grating structure in this embodiment is that when the number of optical signals that can be received per revolution is not limited to the spoke ribs 30, the roller module 14 and the wheel shaft 22, which are relatively expensive, can be shared. For mouse products with different functions, only by adjusting and modifying the light-shielding element 16 at low cost, the benefits of sharing the wheel shaft 22 and highly customizing the grating structure can be realized.
