Description

Technical Field

[0001] This invention relates to a mouse device, and more particularly to a light-emitting mouse device. Background Technology

[0002] A mouse is used to control the cursor on a computer screen and thus operate the computer. Since the world's first mouse was created in the United States in 1968, it has become an indispensable part of computer devices, used in text processing, video game competitions, industrial drafting, design drafting, and media production. Early mice used trackballs to detect mouse movement. With technological advancements and to improve efficiency, this evolved into the optical or laser modules used for movement detection. Furthermore, to enhance functionality and convenience, mice have evolved from the earliest wired single-button mice to today's wireless multi-button scroll wheel mice. To meet the needs of different industries and individual preferences, electronics manufacturers have also begun producing mice with various shapes and sizes to suit the different operational needs of users.

[0003] In recent years, due to the popularity of e-sports games, manufacturers have developed a considerable number of e-sports mice specifically designed for gaming. Besides high sensitivity and precision, e-sports mice must also be ergonomically designed and possess a trendy and eye-catching appearance. To enhance the visual appeal of e-sports mice, optical elements and light-emitting components are typically integrated into the shell to generate various colors of light, creating a dazzling visual effect. However, existing e-sports mice with optical effects only emit light in thin strips on the shell, or in fixed patterns, or only at the bottom. Furthermore, the optical elements on the mouse shell are injection-molded 3D structures, resulting in larger and thicker components. This not only prevents achieving a thinner profile but also increases manufacturing costs. Therefore, addressing these issues is a key focus for those in the field. Summary of the Invention

[0004] One of the objectives of this invention is to provide a mouse device that uses an aspherical light guide plate to guide the light emitted by a light source, so that the mouse device emits light from its entire surface.

[0005] Other objects and advantages of the present invention can be further understood from the technical features disclosed herein.

[0006] To achieve one or more of the above-mentioned objectives, or other objectives, the present invention provides a mouse device, including a housing, at least one aspherical light guide plate, and a light source. The housing includes a top cover and a base assembled together. The top cover includes at least one side surface. The aspherical light guide plate is disposed on the side surface of the top cover. The aspherical light guide plate includes an incident light surface and an exit light surface, which are not parallel to each other, and the exit light surface is opposite to the side surface of the housing. The light source is disposed on the incident light surface of the aspherical light guide plate. The light source emits light, which enters the aspherical light guide plate from the incident light surface and exits through the exit light surface.

[0007] In one embodiment of the present invention, the housing further includes a button plate, which covers the upper cover. The upper cover is located between the button plate and the base, and at least one side of the upper cover is exposed to the button plate. The button plate is used to be pressed to cause the mouse device to output a button signal.

[0008] In one embodiment of the present invention, the light incident surface of the at least one aspherical light guide plate includes a first light incident surface and a second light incident surface. The first light incident surface is adjacent to the second light incident surface. The first light incident surface and the second light incident surface are not parallel to each other. The first light incident surface is far away from the base, and the second light incident surface is close to the base.

[0009] In one embodiment of the present invention, the light source described above is disposed on the first light-incident surface.

[0010] In one embodiment of the present invention, the light source described above is disposed on the second light-incident surface.

[0011] In one embodiment of the present invention, the light source described above is disposed on a first light-incident surface and a second light-incident surface.

[0012] In one embodiment of the present invention, the at least one aspherical light guide plate further includes a bottom surface, which is adjacent to the light incident surface and opposite to the light emitting surface, and the bottom surface has a plurality of diffusion microstructures.

[0013] In one embodiment of the present invention, the above-mentioned top cover further includes a recessed portion recessed from at least one side, and at least one aspherical light guide plate is located in the recessed portion.

[0014] In one embodiment of the present invention, the number of the above-mentioned at least one aspherical light guide plate is two, and the number of at least one side of the top cover is two, these sides are opposite to each other, and these aspherical light guide plates are respectively disposed on the corresponding side.

[0015] In one embodiment of the present invention, the top cover further includes a first recess and a second recess that are recessed from these sides, and the aspherical light guide plates are located in the first recess and the second recess, respectively.

[0016] In one embodiment of the present invention, the light source includes a plurality of light-emitting elements and a flexible circuit board, the light-emitting elements being electrically connected to the flexible circuit board, and the flexible circuit board being electrically connected to the main circuit board of the mouse device.

[0017] In one embodiment of the present invention, the light-emitting elements described above are light-emitting diode chips or miniature light-emitting diode chips.

[0018] In one embodiment of the present invention, the material of the at least one aspherical light guide plate includes polycarbonate, polymethyl methacrylate or polystyrene.

[0019] The mouse device of this invention features an aspherical light guide plate disposed on one side or opposite two sides of the housing. The aspherical light guide plate guides the light emitted by the light source, resulting in overall surface illumination on one side or opposite two sides of the housing. Furthermore, the overall surface illumination of the aspherical light guide plate can guide the light to extend to the bottom of the housing, creating an underglow effect. Moreover, because the aspherical light guide plate is thin and has a flat surface, the mouse device of this invention uses an aspherical light guide plate as the optical element for guiding light, achieving space saving and product thinning, and further reducing manufacturing costs.

[0048] Please see Figures 1 to 5 , Figure 1 This is a schematic diagram of the external structure of a mouse device according to an embodiment of the present invention. Figure 2 for Figure 1 The diagram shows an exploded view of the components of a mouse device. Figure 3 for Figure 1 The diagram shows an exploded view of the mouse device from another perspective.

Figure 5 For along Figure 4 The diagram shows a cross-sectional view of line segment AA.

[0049] like Figures 1 to 5 As shown, the mouse device 1 of this embodiment includes a housing 11, at least one aspherical light guide plate 12, and a light source 13. The housing 11 includes a top cover 111 and a base 112 assembled together, and the top cover 111 of the housing 11 includes at least one side surface 1111. The aspherical light guide plate 12 is disposed on the side surface 1111 of the top cover 111, and the aspherical light guide plate 12 includes a light-incident surface 121 and a light-exiting surface 122. The light-incident surface 121 and the light-exiting surface 122 of the aspherical light guide plate 12 are not parallel to each other, and the light-exiting surface 122 is approximately parallel to the side surface 1111 of the housing 11 relative to the side surface 1111 of the housing 11. The light source 13 is disposed on the light-incident surface 121 of the aspherical light guide plate 12. The light source 12 is used to emit light, and the light is incident from the light-incident surface 121 into the aspherical light guide plate 12 and exits through the light-emitting surface 122.

[0050] It should be noted that, in this embodiment, the number of aspherical light guide plates 12 is, for example, two, and these two aspherical light guide plates 12 are respectively disposed on one side 1111 of the upper cover 111 and the other opposite side 1112. However, the present invention does not limit the number of aspherical light guide plates 12. The number of aspherical light guide plates 12 can be increased or decreased according to the actual needs. For example, aspherical light guide plates 12 can be disposed on only one side of the upper cover 111 or aspherical light guide plates 12 can be disposed on three different sides of the upper cover 111.

[0051] The following is a further description of other detailed structures of the mouse device 1 in this embodiment.

[0052] like Figures 1 to 3 As shown, the housing 11 of the mouse device 1 in this embodiment also includes a button plate 113. The button plate 113 covers the upper cover 111, and the upper cover 111 is located between the button plate 113 and the base 112. When the button plate 113 covers the upper cover 111, two opposite sides 1111 and 1112 of the upper cover 111 are exposed on the button plate 113. The button plate 113 has a plurality of buttons 1130, which are used for user operation and pressing. When any button 1130 is pressed by the user, the switch (not shown in this figure) corresponding to any button 1130 is triggered, thereby enabling the main circuit board (e.g., a switch that can be electrically connected to the switch) to activate the switch. Figure 4 The main circuit board 100 shown generates a key signal and outputs this key signal to a computer device (not shown in this figure) connected to the mouse device 1, thereby causing the computer device 1 to execute the corresponding instruction or function.

[0053] like Figures 1 to 3As shown, the upper cover 111 of the housing 11 in this embodiment further includes a first recess 1113 and a second recess 1114. The first recess 1113 and the second recess 1114 are recessed from the side surface 1111 and the side surface 1112, respectively, and the two aspherical light guide plates 12 are located in the first recess 1113 and the second recess 1114, respectively. It should be noted that when the two aspherical light guide plates 12 are located in the first recess 1113 and the second recess 1114, respectively, the light emitting surfaces 122 of the two aspherical light guide plates 12 will be coplanar with the side surface 1111 and the side surface 1112, respectively.

[0054] like Figures 1 to 5 As shown, the light-incident surface 121 of the aspherical light guide plate 12 in this embodiment includes a first light-incident surface 1211 and a second light-incident surface 1212. The first light-incident surface 1211 is adjacent to the second light-incident surface 1212. The first light-incident surface 1211 and the second light-incident surface 1212 are not parallel to each other. In this embodiment, the first light-incident surface 1211 and the second light-incident surface 1212 are approximately perpendicular to each other. In this case, the first light-incident surface 1211 is located away from the base 112, while the second light-incident surface 1212 is located close to the base 112. In this embodiment, the light source 13 is disposed only on the first portion of the light incident surface 1211 of the aspherical light guide plate 12. However, the present invention is not limited thereto. In other embodiments, the light source 13 may be disposed only on the second portion of the light incident surface 1212 or on both the first portion of the light incident surface 1211 and the second portion of the light incident surface 1212. Furthermore, in this embodiment, the material of the aspherical light guide plate 12 may be, for example, polycarbonate (PC), polymethyl methacrylate (PMMA), or polystyrene (PS). However, the present invention is not limited thereto.

[0055] like Figure 4As shown, the light source 13 in this embodiment includes a plurality of light-emitting elements 131 and a flexible circuit board 132. These light-emitting elements 131 are electrically connected to the flexible circuit board 132, and the flexible circuit board 132 is electrically connected to the main circuit board 100 of the mouse device 1. Specifically, the main circuit board 100 of the mouse device 1 is housed within the accommodating space formed between the upper cover 111 and the base 112 of the housing 11. These light-emitting elements 131 are electrically connected to the main circuit board 100 via the flexible circuit board 132. The flexible circuit board 132, electrically connected to the main circuit board 100, can be powered via the main circuit board 100, and when the flexible circuit board 100 is powered, these light-emitting elements 131 output light into the aspherical light guide plates 12. In this embodiment, these light-emitting elements 131 are, for example, light-emitting diode chips or miniature light-emitting diode chips.

[0056] In this embodiment, these light-emitting elements 131 are packaged in groups of three. The light-emitting elements 131 located in the same package can be red light-emitting diode chips, green light-emitting diode chips, and blue light-emitting diode chips, that is, light sources of the three primary colors of RGB. Through the structure of the package, the light emitted by the three light-emitting elements of RGB can be mixed in the package to generate light of different color temperatures or to achieve the effect of gradient light emission by using the changes of light of different color temperatures.

[0057] like Figures 1 to 5 As shown, the aspherical light guide plate 12 of this embodiment also includes a bottom surface 123. The bottom surface 123 of the aspherical light guide plate 12 is adjacent to the light-incident surface 121 and opposite to the light-outceasing surface 122. That is, the bottom surface 123 is located on the side closer to the housing 11, while the light-outceasing surface 122 is located on the other side away from the housing 11. In this embodiment, the bottom surface 123 of the aspherical light guide plate 12 has a plurality of diffusion microstructures 14. The diffusion microstructures 14 are, for example, dots or other microstructures that can diffuse light, but the present invention is not limited thereto. Furthermore, the distribution density of the multiple diffusion microstructures 14 can be adjusted according to different design requirements or different optical effect requirements. For example, in order to further improve the light emission effect of the side of the light-emitting surface 122 away from the light-incident surface 121 (that is, the position close to the base 112 of the housing 11), the distribution density of these diffusion microstructures 14 can gradually become denser from the direction close to the light-incident surface 121 to the direction away from the light-incident surface 121. Under such a structural design, the aspherical light guide plate 12 can uniformly guide the light emitted by the light source 13 to the bottom position of the housing 11, thereby creating a light emission effect such as under glow.

[0058] Please see Figure 6 This is a schematic diagram of the external structure of a mouse device according to another embodiment of the present invention. Figure 6As shown, the mouse device 1a in this embodiment and Figure 1 Similar to the mouse device 1 shown, the difference is that the aspherical light guide plate 12a in this embodiment is, for example, in a U-shaped configuration. The U-shaped aspherical light guide plate 12a is positioned to cover not only the two opposite sides of the housing 11, but also the surface between the two opposite sides (that is, the surface of the tail of the housing 11).

[0059] It should be noted that the above-mentioned aspherical light guide plate configuration is only one of the embodiments listed in this invention. This invention does not limit the configuration of the aspherical light guide plate. The configuration of the aspherical light guide plate can vary according to the actual needs. For example, it can be made to present the configuration of the manufacturer's trademark according to the manufacturer's requirements, or the configuration of the aspherical light guide plate can be changed to match the grip of the mouse device.

[0060] In summary, the mouse device of this invention has an aspherical light guide plate disposed on one side or opposite two sides of the housing. The aspherical light guide plate guides the light emitted by the light source, resulting in overall surface illumination on one side or opposite two sides of the housing. Furthermore, the overall surface illumination of the aspherical light guide plate can guide the light to extend to the bottom of the housing, creating an underglow effect. Moreover, because the aspherical light guide plate is thin and has a flat surface, the mouse device of this invention uses an aspherical light guide plate as the optical element for guiding light, achieving space saving and product thinning, and further reducing manufacturing costs.

[0061] However, the above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the invention are still within the scope of this patent. Furthermore, no embodiment or claim of the present invention needs to achieve all the objectives, advantages, or features disclosed in the invention. In addition, the abstract and headings are merely for assisting in patent document searches and are not intended to limit the patent scope of the present invention. Furthermore, the terms "first," "second," etc., mentioned in this specification or claims are only used to name elements or distinguish different embodiments or scopes, and are not used to limit the upper or lower limit of the number of elements.
