Description

Technical Field

[0001] The present invention relates to the field of input devices, and particularly to a mouse device. Background Art

[0002] A mouse is used to control the cursor on a computer screen and thus operate the computer. Since the first mouse in the world was made in the United States in 1968, the mouse has become an indispensable part of computer equipment in text processing, video game competitions, industrial drawing, design drawing, or media production. In the early days, the mouse used a trackball for detecting mouse displacement. With the progress of technology and to improve its working efficiency, it has gradually evolved into the form of using an optical or laser module for displacement detection today. In addition, to enhance the functionality and convenience of the mouse, the mouse has evolved from the earliest wired single-button mouse to the current wireless multi-button scroll wheel mouse. In order to meet the needs of different industries or personal preferences, various electronics manufacturers have also started to manufacture various mouse shapes to meet the operating requirements of different users. In addition, how to improve the comfort and sensitivity of mouse buttons such as the left and right buttons, scroll wheel, or operations has gradually attracted people's attention.

[0003] In the current mouse designs on the market, the scroll wheel of the mouse is used for forward and backward rotation operations and pressing trigger operations. When the user rotates the scroll wheel of the mouse forward and backward, the encoder can be driven to rotate by the scroll wheel to generate a sense of paragraph to achieve the function of controlling the scrolling and page turning of the window operation interface. However, the limitation is that the scroll wheel cannot be rotated quickly. Therefore, there are also mouse scroll wheels developed on the market that can simultaneously have a sense of paragraph and fast rotation function, but it is necessary to drive and control the rotation speed of the scroll wheel through an additional motor, which will greatly increase the manufacturing cost. Therefore, how to improve the above problems has become the focus of attention of relevant personnel in this field. Summary of the Invention

[0004] One of the purposes of the present invention is to provide a mouse device, in which the scroll wheel module combines a magnetic ratchet and a permanent magnet to achieve an operation means with both a sense of paragraph and fast rotation.

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

[0006] To achieve one or some or all of the above purposes or other purposes, the present invention provides a mouse device, including a housing and a roller module. The roller module is disposed in the housing. The roller module includes a roller, a carrier, a magnetic ratchet, and at least one permanent magnet. The carrier is used to carry the roller. The carrier includes a first carrying portion and a second carrying portion which are opposite to each other. The roller is pivotally connected between the first carrying portion and the second carrying portion, such that the roller can rotate relative to the carrier. The magnetic ratchet is disposed between the roller and the first carrying portion. The roller can drive the magnetic ratchet to rotate, and the magnetic ratchet includes a plurality of ratchet teeth portions arranged at intervals. The permanent magnet is disposed on the first carrying portion of the carrier. The permanent magnet corresponds to one of these ratchet teeth portions of the magnetic ratchet, and there is a spacing between the permanent magnet and the corresponding ratchet tooth portion. During the process that the roller drives the magnetic ratchet to rotate, magnetic suction forces are generated between these ratchet teeth portions and the permanent magnet respectively.

[0007] In an embodiment of the present invention, the spacing between the permanent magnet and one of these ratchet teeth portions is between 0.05 mm and 1.5 mm.

[0008] In an embodiment of the present invention, the above-mentioned carrier further includes a receiving groove. The receiving groove is disposed on the first carrying portion. The permanent magnet is disposed in the receiving groove, and a part of the permanent magnet protrudes out of the receiving groove.

[0009] In an embodiment of the present invention, the number of the above-mentioned permanent magnets is multiple. These permanent magnets include a first permanent magnet and a second permanent magnet. The carrier further includes a first receiving groove and a second receiving groove. The first receiving groove and the second receiving groove are respectively disposed on the first carrying portion. The first permanent magnet is disposed in the first receiving groove and partially protrudes out of the first receiving groove. The second permanent magnet is disposed in the second receiving groove and partially protrudes out of the second receiving groove. The first permanent magnet corresponds to one of these ratchet teeth portions of the magnetic ratchet, and the second permanent magnet corresponds to another one of these ratchet teeth portions of the magnetic ratchet.

[0010] In an embodiment of the present invention, the above-mentioned first receiving groove is located in a first radial direction of the magnetic ratchet, and the second receiving groove is located in a second radial direction of the magnetic ratchet. There is an included angle between the first radial direction and the second radial direction, and the angle of the included angle is between 45 degrees and 180 degrees.

[0011] In an embodiment of the present invention, the number of the above-mentioned permanent magnets is multiple. A part of these permanent magnets forms a first Halbach array magnetic group, and another part of these permanent magnets forms a second Halbach array magnetic group. The carrier seat further includes a first accommodation groove and a second accommodation groove. The first accommodation groove and the second accommodation groove are respectively arranged on the first bearing part. The first Halbach array magnetic group is arranged in the first accommodation groove and a part of the first Halbach array magnetic group exposes outside the first accommodation groove. The second Halbach array magnetic group is arranged in the second accommodation groove and a part of the second Halbach array magnetic group exposes outside the second accommodation groove. The first Halbach array magnetic group corresponds to one of these ratchet teeth parts of the magnetic ratchet, and the second Halbach array magnetic group corresponds to the other of these ratchet teeth parts of the magnetic ratchet.

[0012] In an embodiment of the present invention, the number of the above-mentioned permanent magnets is multiple. The carrier seat further includes a plurality of accommodation grooves. These accommodation grooves are arranged on the first bearing part. These permanent magnets are respectively arranged in the corresponding accommodation grooves, and these accommodation grooves are respectively located in different radial directions of the magnetic ratchet and are arranged in a radial pattern.

[0013] In an embodiment of the present invention, the above-mentioned housing includes an upper cover and a base assembled with each other. An accommodation space is defined between the upper cover and the base. The roller module is arranged on the base and is located in the accommodation space.

[0014] In an embodiment of the present invention, the above-mentioned roller further includes a rotating shaft. The magnetic ratchet is arranged on the rotating shaft, and these ratchet teeth parts surround the rotating shaft. The roller is pivotally connected between the first bearing part and the second bearing part through the rotating shaft, so that the roller can rotate relative to the carrier seat. During the rotation of the roller, the magnetic ratchet rotates synchronously with the roller.

[0015] In an embodiment of the present invention, the material of the above-mentioned magnetic ratchet is iron, cobalt, nickel or any magnetic metal material.

[0016] The mouse device according to the embodiment of the present invention has a scroll wheel module with a structural design that combines a single permanent magnet or multiple permanent magnets with a magnetically permeable ratchet, so as to achieve an operation means that combines the sense of paragraph and fast rotation when the scroll wheel is rotated. When the user rotates the scroll wheel of the scroll wheel module, the scroll wheel drives the magnetically permeable ratchet to rotate, so that the multiple spaced teeth of the magnetically permeable ratchet respectively pass through the permanent magnet and generate magnetic suction force with the permanent magnet, giving the user a magnetic floating continuous suction and release tactile feeling during the process of rotating the scroll wheel. In addition, an appropriate distance is maintained between the permanent magnet of the scroll wheel module and these tooth portions of the magnetically permeable ratchet, so that the permanent magnet and these tooth portions do not interfere with each other. Under such a structural design, when the user rotates the scroll wheel at a relatively fast speed, an operation tactile feeling like a shuttle rolling can still be generated. The mouse device according to the embodiment of the present invention has a simple structural design for the scroll wheel module, and there is no need to drive and control the rotation speed of the scroll wheel through an additional motor, greatly reducing the manufacturing cost.

[0055] The foregoing 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 accompanying drawings. The directional terms mentioned in the following embodiments, such as: up, down, left, right, front, or back, etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are for illustration and not for limiting the present invention.

[0056] Please refer to Figures 1 to 4 , Figure 1 , which is a three-dimensional structural schematic diagram of a mouse device according to an embodiment of the present invention. Figure 2 is Figure 1 a three-dimensional structural schematic diagram of the mouse device shown in Figure 3 is Figure 2 an exploded schematic diagram of the components of the roller module shown in Figure 4 is a cross-sectional schematic diagram along the Figure 2 AA line segment shown in

[0057] As Figures 1 to 4 shown, the mouse device 1 of this embodiment includes a housing 10 and a roller module 11. The roller module 11 is disposed within the housing 10. Specifically, the housing 10 of this embodiment includes an upper cover 101 and a base 102 that are assembled with each other, and a receiving space is defined between the upper cover 101 and the base 102 of the housing 10. The roller module 11 is disposed on the base 102 of the housing 10 and is located within the receiving space. The surface of the housing 10 of the mouse device 1 has a through hole to communicate with the receiving space of the housing 10, and a part of the roller 110 of the roller module 11 passes through the through hole of the housing 10, so that a part of the roller 110 is exposed outside the housing 10 for the user to operate. The mouse device 1 can be operated or held and moved by the user's hand to control an electronic computer. For example, the cursor displayed on the screen can be moved or the roller 110 can be scrolled to control the up and down movement of the vertical scroll bar of the window operation interface. The other specific implementation manners and operating principles of the user controlling the electronic computer through the mouse device 1 are well known to those skilled in the art, so they will not be elaborated herein.

[0058] As Figures 1 to 4As shown in the figure, the roller module 11 of this embodiment includes a roller 110, a carrier seat 111, a magneto - conductive ratchet 112, and at least one permanent magnet 113. The carrier seat 111 is used to carry the roller 110, and the carrier seat 111 includes a first carrying portion 1111 and a second carrying portion 1112 that face each other. The roller 110 is pivotally connected between the first carrying portion 1111 and the second carrying portion 1112 of the carrier seat 111, so that the roller 110 rotates relative to the carrier seat 111 according to the operation of the user. The magneto - conductive ratchet 112 is disposed between the roller 110 and the first carrying portion 1111 of the carrier seat 111, and the magneto - conductive ratchet 112 includes a plurality of ratchet teeth portions 1120 arranged at intervals. The roller 110 can drive the magneto - conductive ratchet 112 to rotate, that is, during the rotation of the roller 110, the magneto - conductive ratchet 112 rotates synchronously with the roller 110. The permanent magnet 113 is disposed on the first carrying portion 1111 of the carrier seat 111. The permanent magnet 113 corresponds to one of these ratchet teeth portions 1120 of the magneto - conductive ratchet 112, and there is a spacing D between the permanent magnet 113 and the corresponding ratchet tooth portion 1120.

[0059] In this embodiment, when the user rotates the roller 110 of the roller module 11 to make the roller 110 rotate, the magneto - conductive ratchet 112 rotates synchronously with the roller 110. During the synchronous rotation of the magneto - conductive ratchet 112 and the roller 110, these ratchet teeth portions 1120 of the magneto - conductive ratchet 112 will sequentially pass through the permanent magnet 113 respectively and generate magnetic suction force with the permanent magnet 113. It should be particularly noted that the magnetic pole of the permanent magnet 113 facing the ratchet teeth portions 1120 of the magneto - conductive ratchet 112 is, for example, the N - pole, and the magnetic pole of the permanent magnet 113 facing away from the ratchet teeth portions 1120 of the magneto - conductive ratchet 112 is, for example, the S - pole, but the present invention is not limited thereto.

[0060] In this embodiment, the material of the magneto - conductive ratchet 112 is, for example, iron, cobalt or nickel, but the present invention is not limited thereto. In the case where the magneto - conductive ratchet 112 can generate magnetic suction force with the permanent magnet 113, the magneto - conductive ratchet 112 can be any magnetic metal material.

[0061] In this embodiment, the spacing D between the permanent magnet 113 and one of these ratchet teeth portions 1120 of the magneto - conductive ratchet 112 is, for example, between 0.05 mm and 1.5 mm, but the present invention is not limited thereto. When these ratchet teeth portions 1120 of the magneto - conductive ratchet 112 sequentially pass through the permanent magnet 113 respectively, the permanent magnet 113 will maintain the spacing D of 0.05 mm to 1.5 mm with each ratchet tooth portion 1120, thereby enabling the user to generate a magnetic - floating continuous suction and release paragraph feel during the rotation of the roller 110.

[0062] It should be specifically noted that since the permanent magnet 113 of this embodiment is fixed to the first bearing portion 111 of the bearing seat 111, the distance D between the permanent magnet 113 and the ratchet teeth portion 1120 of the magnetic ratchet 112 can maintain a fixed distance under different operating states. Even after long-term use, the user can still feel a consistent paragraph feel when rotating the roller 110. In addition, when the form of the roller module 11 belongs to the structural design of a tilt wheel, when the roller 110 performs a left-right tilting operation, the distance D between the permanent magnet 113 and the ratchet teeth portion 1120 of the magnetic ratchet 112 can still be maintained at a fixed distance, so that the paragraph feel felt when rotating the roller 110 remains consistent.

[0063] The following will further describe other detailed structures of the roller module 11 of this embodiment.

[0064] As Figures 1 to 4 shown, the roller 110 of this embodiment further includes a rotating shaft 1100. The rotating shaft 1100 extends from the center of the roller 110 towards opposite sides. The magnetic ratchet 112 is disposed on the rotating shaft 1100 and is located on one side of the roller 110, and these ratchet teeth portions 1120 of the magnetic ratchet 112 surround the rotating shaft 1100. The roller 110 is pivotally connected between the first bearing portion 1111 and the second bearing portion 1112 of the bearing seat 111 through the rotating shaft 1100, so that the roller 110 can rotate relative to the bearing seat 111 and further drive the magnetic ratchet 112 to rotate simultaneously.

[0065] As Figure 3 And Figure 4 shown, the bearing seat 111 of this embodiment further includes a receiving groove 1113. The receiving groove 1113 is disposed on the first bearing portion 1111 and corresponds to the magnetic ratchet 112. The permanent magnet 113 is disposed in the receiving groove 1113 of the first bearing portion 1111, and a part of the permanent magnet 113 is exposed outside the receiving groove 1113, and the part of the permanent magnet 113 exposed outside the receiving groove 1113 corresponds to one of the ratchet teeth portions 1120 of the magnetic ratchet 112.

[0066] It is worth mentioning that as Figure 4As shown, in this embodiment, a plurality of receiving grooves 1113 can be formed in advance on the first receiving portion 1111 of the carrier base 111. For example, four receiving grooves 1113 are formed on the first receiving portion 1111. These receiving grooves 1113 are arranged radially in different radial directions of the magnetic ratchet 112, but the present invention does not limit the number of receiving grooves 1113. The number of receiving grooves 1113 can be increased or decreased according to actual requirements. In this embodiment, since the number of permanent magnets 113 is one, a single permanent magnet 113 can be placed in one of these receiving grooves 1113. In other embodiments, in order to make the paragraph feel more distinct when rotating the roller 110, the number of permanent magnets 113 can be increased to two or more, and these permanent magnets 113 are placed in the corresponding receiving grooves 1113 to enhance the magnetic attraction force on the magnetic ratchet 12.

[0067] The actuation method of the roller module 11 of the embodiment of the present invention will be further described in detail below.

[0068] As Figures 2 to 4 shown, the ratchet teeth 1120 of the magnetic ratchet 112 in this embodiment are arranged at intervals, that is, there is a gap G between two adjacent ratchet teeth 1120 among these ratchet teeth 1120. When the user rotates the roller 110 of the roller module 11 to drive the magnetic ratchet 112 to rotate, each ratchet tooth 1120 of the magnetic ratchet 112 and the gap G between two adjacent ratchet teeth 1120 will sequentially pass through the permanent magnet 113. When the ratchet tooth 1120 moves to the position corresponding to the permanent magnet 113, a magnetic attraction force will be generated between the permanent magnet 113 and the ratchet tooth 1120. When the gap G between two adjacent ratchet teeth 1120 moves to the position corresponding to the permanent magnet 113, a very weak magnetic attraction force or no magnetic attraction force will be generated between the permanent magnet 113 and the gap G. In the case where each ratchet tooth 1120 and each gap G alternately pass through the permanent magnet 113, a magnetic floating continuous suction and release paragraph feel is generated for the user during the process of rotating the roller 110, and the function of controlling the scrolling and paging of the window operation interface or other related operations is further achieved.

[0069] It is worth mentioning that an appropriate distance D is maintained between the permanent magnet 113 and the ratchet teeth 1120 of the magnetic ratchet 112 in this embodiment. That is to say, during the process of the roller 110 driving the magnetic ratchet 112 to rotate, the permanent magnet 113 and these ratchet teeth 1120 will not interfere with each other. Therefore, when the user rotates the roller 110 at a relatively high speed, an operation feel like a shuttle rolling can still be generated.

[0070] Please refer to Figure 5With Figure 6 , Figure 5 is a schematic cross-sectional view of the mouse device according to another embodiment of the present invention with some components omitted. Figure 6 is Figure 5 an exploded schematic view of the components of the roller module shown in. As Figure 5 With Figure 6 shown, the mouse device 1a of this embodiment is similar to the mouse device 1 shown in Figures 1 to 4 , the difference being that the number of permanent magnets of the roller module 11a of the mouse device 1a of this embodiment is two. The roller module 11a of this embodiment includes a first permanent magnet 1131 and a second permanent magnet 1132. The first permanent magnet 1131 is placed in the first receiving groove 11131, and a part of the first permanent magnet 1131 is exposed outside the first receiving groove 11131. The second permanent magnet 1132 is placed in the second receiving groove 11132, and a part of the second permanent magnet 1132 is exposed outside the second receiving groove 11132. When the roller 110 is not rotated and is in a stationary state, the first permanent magnet 1131 corresponds to one of these tooth portions 1120 of the magnetic ratchet 112, and the second permanent magnet 1132 corresponds to another one of these tooth portions 1120 of the magnetic ratchet 112.

[0071] It is worth mentioning that, in this embodiment, the first receiving groove 11131 for placing the first permanent magnet 1131 is located in the first radial direction D1 of the magnetic ratchet 112, and the second receiving groove 11132 for placing the second permanent magnet 1132 is located in the second radial direction D2 of the magnetic ratchet 112, and there is an included angle θ between the first radial direction D1 and the second radial direction D2. In this embodiment, the angle of the included angle θ between the first radial direction D1 and the second radial direction D2 is, for example, 90 degrees. With such a structural design, the arrangement positions of the first permanent magnet 1131 and the second permanent magnet 1132 are evenly distributed on the periphery of the magnetic ratchet 112, so as to generate magnetic attraction between the first permanent magnet 1131 and the second permanent magnet 1132 and the magnetic ratchet 112 at appropriate positions.

[0072] It should be specifically noted that the angle of the included angle θ between the above-mentioned first radial direction D1 and the second radial direction D2 being 90 degrees is only one of the embodiments of the present invention, but the present invention is not limited thereto. In other embodiments, the angle of the included angle θ between the first radial direction D1 and the second radial direction D2 is, for example, 45 degrees, 125 degrees, 180 degrees or greater than 180 degrees.

[0073] As described above, the mouse device 1a of this embodiment increases the number of permanent magnets of the roller module 11a to two. With such a structural design, in addition to providing the user with a magnetic floating continuous suction and release paragraph feel, the roller 110 can also rotate more smoothly and the paragraph feel is clearer and more distinct. It should be particularly noted that the number of the above-mentioned permanent magnets being two is only one of the embodiments of the present invention, but the present invention is not limited thereto. In other embodiments, the number of permanent magnets can be increased to more than two according to actual requirements.

[0074] Please refer to Figure 7 and Figure 8 , Figure 7 which is a schematic cross-sectional view of a mouse device according to another embodiment of the present invention with some components omitted. Figure 8 is Figure 7 an exploded schematic view of the components of the roller module shown. As Figure 7 and Figure 8 shown, the mouse device 1b of this embodiment is similar to the mouse device 1a shown in Figure 5 , Figure 6 . The difference is that a part of the multiple permanent magnets of the roller module 11b of the mouse device 1b of this embodiment forms a first Halbach array magnetic group 1133, and another part of these permanent magnets forms a second Halbach array magnetic group 1134. In this embodiment, the first Halbach array magnetic group 1133 is placed in the first receiving groove 11131, and a part of the first Halbach array magnetic group 1133 is exposed outside the first receiving groove 11131. The second Halbach array magnetic group 1134 is placed in the second receiving groove 11132, and a part of the second Halbach array magnetic group 1134 is exposed outside the second receiving groove 11132. When the roller 110 is not rotated and is in a stationary state, the first Halbach array magnetic group 1133 corresponds to one of these tooth portions 1120 of the magnetic ratchet 112, and the second Halbach array magnetic group 1134 corresponds to the other of these tooth portions 1120 of the magnetic ratchet 112.

[0075] Specifically, in this embodiment, the first Halbach array magnetic group 1133 and the second Halbach array magnetic group 1134 respectively include a first part of permanent magnets P1, a second part of permanent magnets P2, and a third part of permanent magnets P3. The first part of permanent magnets P1 is stacked above the second part of permanent magnets P2, the third part of permanent magnets P3 is stacked below the second part of permanent magnets P2, and the second part of permanent magnets P2 is located between the first part of permanent magnets P1 and the third part of permanent magnets P3. In addition, the magnetic pole arrangement of the first Halbach array magnetic group 1133 and the second Halbach array magnetic group 1134 is such that the first part of permanent magnets P1 are N poles and S poles in sequence in the longitudinal arrangement direction (vertical arrangement direction), and the S pole of the first part of permanent magnets P1 faces the second part of permanent magnets P2. The second part of permanent magnets P2 are S poles and N poles in sequence in the transverse arrangement direction (horizontal arrangement direction), and the S pole of the second part of permanent magnets P2 is adjacent to one of the tooth portions 1120 of the magnetic conduction ratchet 112. The third part of permanent magnets P3 are S poles and N poles in sequence in the longitudinal arrangement direction (vertical arrangement direction), and the S pole of the third part of permanent magnets P3 faces the second part of permanent magnets P2. With the structural design of these permanent magnets as Halbach array magnetic groups, the magnetic attraction force between these permanent magnets and the tooth portions 1120 of the magnetic conduction ratchet 112 can be further increased. It should be particularly noted that the above magnetic pole arrangement of the Halbach array magnetic group is only one of the implementation manners of the present invention, and the present invention is not limited thereto. The magnetic pole arrangement of the Halbach array magnetic group can be different according to actual requirements.

[0076] As can be seen from the above, the mouse device 1b of this embodiment increases the number of permanent magnets of the roller module 11b to a plurality, and these permanent magnets respectively form a first Halbach array magnetic group 1133 and a second Halbach array magnetic group 1134. With such a structural design, in addition to providing the user with a magnetic floating continuous suction and release paragraph feel, the roller 110 can also rotate more smoothly and the paragraph feel is more clear and distinct. It should be particularly noted that the above design of the permanent magnets as two Halbach array magnetic groups is only one of the embodiments of the present invention, but the present invention is not limited thereto. In other embodiments, the number of Halbach array magnetic groups can be increased to more than two according to actual requirements.

[0077] It is worth mentioning that, in other embodiments, it is also possible to Figure 5 , Figure 6 shown single permanent magnet and Figure 7 , Figure 8 shown Halbach array magnetic group are used in combination, that is, the single permanent magnet and the Halbach array magnetic group are respectively placed in different accommodation grooves of the carrier.

[0078] In summary, for the mouse device according to the embodiments of the present invention, the scroll wheel module is designed with a structure in which a single permanent magnet or multiple permanent magnets are combined with a magnetically permeable ratchet, so as to achieve an operation means that combines the sense of paragraph and fast rotation when the scroll wheel is rotated. When the user rotates the scroll wheel of the scroll wheel module, the scroll wheel drives the magnetically permeable ratchet to rotate, so that the multiple spaced ratchet teeth of the magnetically permeable ratchet respectively pass through the permanent magnet and generate magnetic attraction with the permanent magnet, giving the user a magnetic floating continuous suction and release tactile feeling during the process of rotating the scroll wheel. In addition, an appropriate distance is maintained between the permanent magnet of the scroll wheel module and these ratchet teeth of the magnetically permeable ratchet, so that the permanent magnet and these ratchet teeth do not interfere with each other. With such a structural design, when the user rotates the scroll wheel at a relatively high speed, an operation tactile feeling like a shuttle rolling can still be generated. For the mouse device according to the embodiments of the present invention, the structural design of the scroll wheel module is simple, and there is no need to drive and control the rotation speed of the scroll wheel through an additional motor, greatly reducing the manufacturing cost.

[0079] However, as described above, it is only a preferred embodiment of the present invention, and the scope of implementation of the present invention cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the claims of the present invention and the content of the invention description still fall within the scope covered by the patent of the present invention.
