Description

Technical Field

[0001] This application relates to the field of mouse technology, and in particular to a scroll wheel module and a mouse device. Background Technology

[0002] With the rapid development of technology and the advent of the multimedia and computer age, people's dependence on computer devices has increased. Therefore, peripheral input devices play a very important role between computer systems and users. These peripheral input devices include: mouse, keyboard and microphone. Since the mouse can be held by the user to control the movement of the mouse cursor, and the movement trajectory of the mouse cursor is output by the computer screen, this operation method is close to human usage habits, making the mouse the most common peripheral input device.

[0003] However, the roller structure in the related technology is relatively complex, and the operation of switching between smooth mode and paragraph mode is relatively complicated, which makes it prone to failure under frequent use. Utility Model Content

[0004] Therefore, it is necessary to provide a mouse device with a simple structure, convenient operation, and reduced malfunction issues, including a scroll wheel module and a mouse device.

[0005] A scroll wheel module for a mouse device, comprising:

[0006] A roller, comprising a rolling element and a rotating shaft, wherein the rotating shaft is connected to the rolling element and the rolling element is provided with annular teeth;

[0007] A passive member, the passive member including an abutment portion and a first magnetic member, the abutment portion being configured to move following the first magnetic member, and the abutment portion being separated from or abutting against the annular tooth portion;

[0008] An active component, comprising a magnetic conversion component and a second magnetic component, wherein the second magnetic component is disposed opposite to the first magnetic component, and the magnetic conversion component is used to cause the polarity of the second magnetic component to be reversed, so as to control the second magnetic component to attract or repel the first magnetic component;

[0009] When the second magnetic element attracts the first magnetic element, it can drive the passive element to move away from the annular teeth, so that the abutting part separates from the annular teeth, and the roller is in a smooth mode.

[0010] When the second magnetic element repels the first magnetic element, it can drive the passive element to move in a direction close to the annular teeth so that the abutting part abuts against the annular teeth, thereby putting the roller in a segmented mode.

[0011] In one embodiment, the magnetic conversion element includes a driving element connected to the second magnetic element. The driving element is used to drive the second magnetic element to rotate, so that the polarity of the second magnetic element relative to the first magnetic element is reversed.

[0012] In one embodiment, when the roller is in segment mode, the first magnetic element and the second magnetic element are spaced apart in a vertical direction perpendicular to the axis of rotation.

[0013] In one embodiment, when the roller is in segment mode, the first magnetic element and the second magnetic element are spaced apart in a horizontal direction perpendicular to the axis of rotation.

[0014] In one embodiment, the scroll wheel module of the mouse device further includes a fixed shaft, and the passive member further includes a connector hinged to the fixed shaft. The abutment portion and the first magnetic member are respectively disposed at opposite ends of the connector, and the abutment portion and the first magnetic member are located on the same side of the connector.

[0015] In one embodiment, the end of the connector away from the first magnetic element has the abutting portion protruding toward the annular toothed portion.

[0016] In one embodiment, the abutting portion has an arcuate surface that abuts against the annular toothed portion.

[0017] In one embodiment, the annular toothed portion includes a plurality of teeth disposed on the inner peripheral wall of the roller, the plurality of teeth being evenly spaced along the axial direction of the roller, and a groove being formed between adjacent teeth.

[0018] This application also provides a mouse device, characterized in that it includes a housing and a scroll wheel module of the mouse device as described above, wherein the scroll wheel module of the mouse device is disposed within the housing, and the scroll wheel extends at least partially out of the housing.

[0019] In one embodiment, the housing is provided with a mounting bracket for supporting the rotating shaft, and the rotating shaft is rotatable on the mounting bracket.

[0020] In the above solution, by setting a passive component and an active component, the magnetic conversion component can cause the polarity of the second magnetic component to change, thereby controlling whether the second magnetic component attracts or repels the first magnetic component. When the second magnetic component attracts the first magnetic component, it can drive the passive component to move away from the annular teeth, so that the contact part separates from the annular teeth, making the roller operate in a smooth mode. When the second magnetic component repels the first magnetic component, it can drive the passive component to move towards the annular teeth, so that the contact part abuts against the annular teeth, making the roller operate in a segmented mode. This application has a simple structure. By controlling the magnetic conversion component to cause the polarity of the second magnetic component to change, it can control whether the second magnetic component attracts or repels the first magnetic component, thereby controlling the roller to switch between smooth and segmented modes. It is also easy to operate and reduces the problem of malfunctions. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0032] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The embodiments of this application relate to a scroll wheel module 10 of a mouse device, including a scroll wheel 100, a passive component 200 and an active component 300. The scroll wheel 100 is rotatably configured, and the passive component 200 and the active component 300 cooperate with each other to switch the rotation of the scroll wheel 100 between a smooth mode and a segmented mode.

[0035] The roller 100 includes a rolling element 110 and a rotating shaft 120. The rotating shaft 120 is connected to the rolling element 110, and a bearing 130 is provided between the rotating shaft 120 and the rolling element 110. The rolling element 110 rotates around the rotating shaft 120. The rolling element 110 is provided with annular teeth 111. More specifically, the rolling element 110 is operable by a user. When the user moves the rolling element 110, the annular teeth 111 rotate synchronously with the rolling element 110.

[0036] The outer wall of the rolling element 110 is provided with skin-friendly silicone 140. Skin-friendly silicone 140 is typically very soft, with a texture similar to human skin, a smooth and delicate surface, providing a comfortable tactile experience and avoiding skin irritation and friction. Skin-friendly silicone 140 has good elasticity, quickly returning to its original shape after being subjected to external force, allowing it to adapt to different shapes and pressures when in contact with the skin, providing a close fit. Skin-friendly silicone 140 has excellent biocompatibility, is non-toxic to human tissues, does not cause allergic reactions, and will not cause skin inflammation or other adverse reactions; therefore, it can be in contact with the skin for extended periods without causing harm.

[0037] The passive member 200 includes an abutment portion 210 and a first magnetic member 220. The abutment portion 210 is configured to move with the first magnetic member 200, and the abutment portion 210 is either separated from or abuts against the annular toothed portion 111. Specifically, the abutment portion 210 moves synchronously with the first magnetic member 200.

[0038] The active component 300 includes a magnetic conversion component 310 and a second magnetic component 320. The second magnetic component 320 is disposed opposite to the first magnetic component 220. The magnetic conversion component 310 is used to cause the polarity of the second magnetic component 320 to be reversed, so as to control the second magnetic component 320 to attract or repel the first magnetic component 220.

[0039] When the second magnetic element 320 attracts the first magnetic element 220, it can drive the passive element 200 to move away from the annular toothed portion 111, so that the abutting portion 210 separates from the annular toothed portion 111, and the roller 100 is in a smooth mode. Specifically, when the second magnetic element 320 attracts the first magnetic element 220, the polarity of the end of the second magnetic element 320 near the first magnetic element 220 is opposite to the polarity of the end of the first magnetic element 220 near the second magnetic element 320.

[0040] When the second magnetic element 320 repels the first magnetic element 220, it drives the passive element 200 to move in the direction close to the annular toothed portion 111, so that the abutting portion 210 abuts against the annular toothed portion 111, causing the roller 100 to be in a segmented mode. Specifically, when the second magnetic element 320 repels the first magnetic element 220, the polarity of the end of the second magnetic element 320 near the first magnetic element 220 is the same as the polarity of the end of the first magnetic element 220 near the second magnetic element 320. The repulsion between the second magnetic element 320 and the first magnetic element 220 provides the user with a smoother tactile feel, and the smooth damping does not produce a strong sense of abruptness or stickiness, thus improving the user experience.

[0041] It should be noted that the second magnetic element 320 has a first end and a second end that are arranged opposite to each other. The end of the first magnetic element 220 closer to the second magnetic element 320 is the N pole or the S pole. The first end of the second magnetic element 320 is the N pole, and the second end of the second magnetic element 320 is the S pole. By controlling the magnetic conversion element 310 to make the second magnetic element 320 change polarity, it is possible to control the attraction or repulsion between the second magnetic element 320 and the first magnetic element 220, thereby controlling the roller 100 to switch between smooth mode and segment mode. The structure is simple.

[0042] Please see Figure 1 , Figure 2 and Figure 3According to some embodiments of this application, optionally, the magnetic conversion element 310 includes a driving element connected to the second magnetic element 320. The driving element drives the second magnetic element 320 to rotate, thereby reversing the polarity of the second magnetic element 320 relative to the first magnetic element 220. Specifically, the driving element is a motor, and its power output end is connected to the second magnetic element 320. The driving element drives the second magnetic element 320 to rotate, so that the first end and the second end of the second magnetic element 320 are respectively positioned opposite to the end of the first magnetic element 220 closest to the second magnetic element 320.

[0043] In one embodiment, when the roller 100 is in segment mode, the first magnetic element 220 and the second magnetic element 320 are spaced apart in a vertical direction perpendicular to the axis of rotation 120. That is, the first magnetic element 220 is located above or below the second magnetic element 320. In this embodiment, the first magnetic element 220 is located above the second magnetic element 320.

[0044] In another embodiment, when the roller 100 is in segment mode, the first magnetic element 220 and the second magnetic element 320 are spaced apart in a horizontal direction perpendicular to the axial direction of the rotating shaft 120. That is, the first magnetic element 220 is located to the left or right of the second magnetic element 320. In this embodiment, the first magnetic element 220 is located to the left of the second magnetic element 320.

[0045] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the scroll wheel structure 10 of the mouse device further includes a fixed shaft 400, and the passive member 200 further includes a connector 230 hinged to the fixed shaft 400. An abutment portion 210 and a first magnetic member 220 are respectively disposed at opposite ends of the connector 230, and the abutment portion 210 and the first magnetic member 220 are located on the same side of the connector 230. The connector 230 is rotatable relative to the fixed shaft 400. Specifically, the abutment portion 210 and the first magnetic member 220 are respectively disposed at both ends of the connector 230 in the length direction, and the abutment portion 210 and the first magnetic member 220 are located on the same side of the connector 230 in the width direction.

[0046] When the second magnetic element 320 attracts the first magnetic element 220, the first magnetic element 220 disposed at one end of the connector 230 moves in a direction closer to the second magnetic element 320, and the abutting portion 210 disposed at the other end of the connector 230 moves in a direction away from the annular tooth portion 111.

[0047] When the second magnetic element 320 repels the first magnetic element 220, the first magnetic element 220 disposed at one end of the connector 230 moves away from the second magnetic element 320, and the abutting portion 210 disposed at the other end of the connector 230 moves towards the annular tooth portion 111.

[0048] Specifically, the connector 230 includes a first connecting portion, a second connecting portion, and a third connecting portion disposed between the first connecting portion and the second connecting portion. An abutment portion 210 is disposed on the first connecting portion. A first magnetic element 220 is disposed on the second connecting portion. The third connecting portion is hinged to the fixed shaft 400. To ensure that the abutment portion 210 and the first magnetic element 220 are located on the same side of the connector 230, bending portions are provided between the first connecting portion and the third connecting portion, and between the second connecting portion and the third connecting portion.

[0049] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the end of the connector 230 away from the first magnetic member 220 is provided with an abutment portion 210 protruding toward the annular tooth portion 111. Specifically, the abutment portion 210 has an arcuate surface that abuts against the annular tooth portion 111.

[0050] By setting an arc-shaped surface, the jerking and sticking sensations caused by the contact part 210 abutting against the annular toothed part 111 on the roller 100 can be effectively reduced, thus improving the user experience.

[0051] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, the annular toothed portion 111 includes a plurality of teeth disposed on the inner peripheral wall of the roller 100, the plurality of teeth being evenly spaced along the axial direction of the roller 100, and a groove being formed between adjacent teeth.

[0052] Specifically, the rotating shaft 120 is connected to the middle of the rolling element 110, and the annular toothed part 111 is disposed on the inner peripheral wall of the roller 100. There is a cavity between the rotating shaft 120 and the annular toothed part 111. The abutting part 210 disposed at the other end of the connecting member 230 is located in the cavity. The structure is simple and does not require a complicated structure. At the same time, it can make reasonable use of space and reduce the area occupied. Moreover, the cavity between the rotating shaft 120 and the annular toothed part 111 can play a role in weight reduction, making the roller 100 structure lighter.

[0053] Please see Figure 1 , Figure 2 and Figure 3This application also provides a mouse device, including a housing 500 and a scroll wheel structure 10 of the mouse device. The scroll wheel structure 10 of the mouse device is disposed inside the housing 500, and the scroll wheel 100 extends at least partially out of the housing 500 for user operation.

[0054] Please see Figure 1 , Figure 2 and Figure 3 According to some embodiments of this application, optionally, a mounting bracket 510 is provided on the housing 500. The mounting bracket 510 is used to support the rotating shaft 120, and the rotating shaft 120 is rotatable on the mounting bracket 510. Specifically, the mounting bracket 510 includes a first sidewall 511, a second sidewall, a third sidewall 512, and a fourth sidewall connected in sequence. The first sidewall 511, the second sidewall, the third sidewall 512, and the fourth sidewall together enclose a receiving space.

[0055] Both the first sidewall 511 and the opposite third sidewall 512 are provided with support frames 520. Each support frame 520 has a rotating groove 521, in which a rotating shaft 120 is rotatably disposed. At least partially, the rolling element 110 is disposed within the receiving space. The third sidewall 512 is also provided with a fixing frame 530, on which a fixing shaft 400 is disposed. Exemplarily, the fixing shaft 400 is disposed at the top of the fixing frame 530.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
