Abstract

According to the mouse mainboard assembly and the mouse, when a user pokes a mouse wheel in the axial direction of the mouse wheel, an installation frame can swing under the action of the poking force, so that a first pressing piece and a second pressing piece swing along with the installation frame, the first pressing piece can press a first trigger switch in the swing process, and the second pressing piece can press a second trigger switch in the swing process. The second pressing piece can press the second trigger switch in the swinging process, so that the mouse wheel is additionally provided with two key functions on the basis of the original rolling control function. Due to the fact that the first pressing piece and the second pressing piece are arranged on the installation frame in the protruding mode, the acting force transmitted to the first pressing piece and the second pressing piece from the mouse wheel is more stable and controllable, and the movement stroke of the first pressing piece and the movement stroke of the second pressing piece are easier to control. Therefore, the first pressing piece and the second pressing piece can effectively press the first trigger switch and the second trigger switch every time, so that the side pressing control sensitivity of the mouse roller is improved, and the use effect of the mouse is improved.

[0048] With the popularization of computers, the mouse, an important input device at this stage, has a basic form of left and right buttons, and a middle scroll wheel to realize functions such as page turning. Among them, the mouse scroll wheel is connected to the mouse encoder to drive it to rotate to realize the use function. In the related technology, the mouse adopts a left and right swinging method to increase the multi-button function, but the existing scroll wheel swinging structure is complicated, and the actual product is prone to the problem of scroll wheel deviation. At the same time, the swing angle is large and the response is not sensitive enough, which affects the use effect of the mouse.

[0049] The utility model provides a mouse mainboard component, aiming to solve the technical problem of how to improve the use effect of the mouse.

[0050] In the embodiment of the present utility model, Figures 1 to 6 As shown, Figure 1 This is a structural schematic diagram of an embodiment of a mouse motherboard assembly of the utility model; Figure 2 This is a structural schematic diagram of another embodiment of the mouse motherboard assembly of the utility model; Figure 3 This is a structural exploded view of an embodiment of a mouse motherboard assembly of the utility model; Figure 4 This is a structural exploded view of another embodiment of the mouse motherboard assembly of the utility model; Figure 5 It is a structural cross-sectional view of an embodiment of a mouse motherboard assembly of the utility model; Figure 6 This is a structural cross-sectional view of another embodiment of the mouse motherboard assembly of the present invention.

[0051] The mouse mainboard assembly comprises: a mainboard 10; a first trigger switch 11 and a second trigger switch 12, wherein the first trigger switch 11 and the second trigger switch 12 are mounted on the mainboard 10 and are spaced apart along the width direction of the mainboard 10. A mounting frame 20, wherein the mounting frame 20 is swingably mounted between the first trigger switch 11 and the second trigger switch 12, and the swing axis of the mounting frame 20 extends along the length direction of the main board 10; the mounting frame 20 is provided with a first pressing member 21 and a second pressing member 22 on both side walls along the width direction, respectively, the first pressing member 21 is used to press the first trigger switch 11 as the mounting frame 20 swings, and the second pressing member 22 is used to press the second trigger switch 12 as the mounting frame 20 swings; a grating encoder 30, wherein the grating encoder 30 is mounted on the mounting frame 20 and is electrically connected to the main board 10; a mouse wheel 40, wherein the mouse wheel 40 is rotatably mounted on the mounting frame 20, and the mouse wheel 40 includes a wheel body 41 and a rotating shaft 42, and the rotating shaft 42 is connected to the grating encoder 30.

[0052] In this embodiment, the mouse further includes a housing, the main board 10 and the grating encoder 30 are arranged in the housing, the wheel body 41 of the mouse wheel 40 is partially located in the housing and partially located outside the housing, and the part of the wheel body 41 located outside the housing is used for the user to turn. The main board 10 is a circuit board, specifically a hard circuit board, and the main board 10 can provide power to the grating encoder 30 and transmit control signals.

[0053] Specifically, Figure 7 and Figure 8 As shown, Figure 7 It is a structural exploded view of an embodiment of a grating encoder 30 in the utility model; Figure 8 It is a structural exploded view of another embodiment of the grating encoder 30 in the present invention.

[0054] The grating encoder 30 includes a housing 31, a grating component and a circuit board 35. The housing 31 is provided with an installation cavity and a fixing hole 311. The installation cavity is communicated with the fixing hole 311, and the fixing hole 311 is connected to the rotating shaft 42. The grating component can be rotatably installed in the installation cavity. The grating component includes a rotating cylinder 321 and a grating disk 322 sleeved on the outside of the rotating cylinder 321. The rotating cylinder 321 is coaxially arranged with the fixing hole 311 for connection with the rotating shaft 42 of the mouse wheel 40. The grating disk 322 has a plurality of light-transmitting grooves 323 distributed at intervals along the circumferential direction. The circuit board 35 is installed in the installation cavity. The circuit board 35 is electrically connected with a light emitter and a light receiver. The circuit board 35 is electrically connected with the main board 10. The light emitter and the light receiver are connected to form an optical path. When the rotating cylinder 321 rotates, the grating disk 322 is driven by the rotating cylinder 321 so that the grating disk 322 blocks or exposes the optical path.

[0055] By manually turning the mouse wheel 40, a force is generated to drive the grating component to rotate (because the rotating shaft 42 of the mouse wheel 40 is plugged into the rotating cylinder 321). The circuit board 35 is electrically connected to the main board 10 to achieve a conductive state, and then the rotating shaft 42 of the mouse wheel 40 is inserted into the rotating cylinder 321 from the fixing hole 311. At this time, the mouse wheel 40 and the grating component are in a coaxial state. Therefore, when the mouse wheel 40 is turned by the user, the mouse wheel 40 can drive the grating disk 322 connected thereto to rotate synchronously through the rotating shaft 42. At this time, the grating disk 322 can first block the optical path formed between the optical transmitter and the optical receiver and then expose the optical path again. The circuit board 35 can detect that the optical signal of the optical path changes first, and then identify the rolling state of the mouse wheel 40, so that the mouse can complete the corresponding command input work according to the rolling of the mouse wheel 40.

[0056] It is worth noting that, in some embodiments, the optical receiver may be two units integrated on the same component, namely, a first receiving unit and a second receiving unit, wherein the first receiving unit corresponds to "clockwise rotation of the grating disk 322", and the second receiving unit corresponds to "counterclockwise rotation of the grating disk 322". When the mouse wheel 40 is driven by the user to rotate counterclockwise, the mouse wheel 40 can drive the grating disk 322 connected thereto to rotate synchronously. At this time, the grating disk 322 can first block the second optical path formed between the optical transmitter and the second receiving unit and then expose the optical path again. The circuit board 35 can detect the change in the optical signal of the second optical path, and then identify the counterclockwise rotation of the mouse wheel 40, so that the mouse can complete the corresponding command input work according to the counterclockwise rolling of the mouse wheel 40.

[0057] The shell 31 may be made of plastic, metal, or a combination of plastic and metal. The shell 31 made of plastic is relatively light and helps to reduce the overall volume of the mouse, making it easier for users to use it. The shell 31 made of metal has relatively strong strength and helps to extend the service life of the shell 31. Therefore, in some embodiments, part of the material may be metal and part of the material may be plastic.

[0058] The light emitter and the light receiver can be fixed to the circuit board 35 by welding, so as to realize electrical connection while realizing mechanical connection. Of course, in some embodiments, the light emitter and the light receiver can also be fixedly connected to the circuit board 35 by plugging. The grating encoder 30 uses infrared to send and receive signals, and there is no substantial contact when the roller works, so it has good stability and long life.

[0059] The first trigger switch 11 and the second trigger switch 12 are electrically connected to the mainboard 10. By electrically connecting the first trigger switch 11 and the second trigger switch 12 to the preset control circuit on the mainboard 10, the preset control function of the computer can be realized when the first trigger switch 11 and the second trigger switch 12 are pressed, such as turning the page forward and turning the page backward of the document. Thus, the mouse wheel 40 can add two button functions on the basis of the original scrolling control.

[0060] The mouse wheel 40 and the grating encoder 30 are installed on the mounting frame 20, and the mounting frame 20 can swing relative to the mainboard 10. Therefore, when the part of the wheel body 41 exposed outside the outer shell is subjected to an axial thrust, the thrust can drive the mounting frame 20 to swing around the swing axis, and the grating encoder 30 and the mouse wheel 40 will also swing with the mounting frame 20 to keep the connection state of the mouse wheel 40 and the grating encoder 30 stable.

[0061] The first pressing member 21 and the second pressing member 22 are respectively protruded from the left and right side walls of the mounting frame 20, and are respectively located above the first trigger switch 11 and the second trigger switch 12. When the mounting frame 20 swings, the first pressing member 21 and the second pressing member 22 use the mounting frame 20 as a lever to move one of them away from the mainboard 10 and the other closer to the mainboard 10. For example, the first pressing member 21 is close to the mainboard 10 and the second pressing member 22 is away from the mainboard 10. At this time, the first pressing member 21 close to the mainboard 10 will press the first trigger switch 11 to start the functional circuit controlled by the first trigger switch 11.

[0062] Specifically, Figures 3 to 5As shown, the mouse motherboard assembly also includes a first support member 51 and a second support member 52, and the first support member 51 and the second support member 52 are respectively located on the front and rear sides of the mounting frame 20, and the first support member 51 is provided with a first connecting hole 53, and the second support member 52 is provided with a second connecting hole 54; the front and rear end walls of the mounting frame 20 are respectively provided with a first connecting shaft 23 and a second connecting shaft 24, the first connecting shaft 23 and the first connecting hole 53 are rotatably matched, and the second connecting shaft 24 and the second connecting hole 54 are rotatably matched; the first connecting shaft 23 and the second connecting shaft 24 are coaxially arranged with the swing axis of the mounting frame 20.

[0063] The front and rear sides of the mounting frame 20 are the sides in the length direction of the mounting frame 20, and the left and right sides of the mounting frame 20 are the sides in the width direction of the mounting frame 20. The swing axis of the mounting frame 20 is the axis of the first connecting hole 53 and the second connecting hole 54. By rotating the first connecting shaft 23 and the first connecting hole 53, and rotating the second connecting shaft 24 and the second connecting hole 54, the first support member 51 and the second support member 52 can support the mounting frame 20 to rotate, thereby improving the swing stability of the mounting frame 20.

[0064] The first supporting member 51 and the second supporting member 52 can be connected to the mainboard 10 or to the bottom shell of the mouse, which is not limited here.

[0065] Specifically, Figure 3 and Figure 4 As shown, the mouse motherboard assembly also includes a support plate 50, the motherboard 10 is installed on the support plate 50, and the first support member 51 and the second support member 52 are connected to the support plate 50 and pass through the side of the motherboard 10 away from the support plate 50. The support plate 50 is located below the motherboard 10, and the support plate 50 can be used for the motherboard 10 to be installed and fixed, so as to improve the installation stability of the motherboard 10 in the mouse housing. The first support member 51 and the second support member 52 are protruding from the motherboard 10, so as to prevent the motherboard 10 from being subjected to the force of the first support member 51 and the second support member 52, that is, to prevent the motherboard 10 from being subjected to the gravity of structures such as the mouse wheel 40, the mounting frame 20 and the grating encoder 30, so as to prevent the motherboard 10 from being damaged due to excessive force, so as to improve the structural stability of the motherboard 10.

[0066] In practical applications, the support plate 50 can be used as a part of the bottom shell of the mouse, that is, as the bottom plate of the mouse, so that the internal structure of the mouse can be simpler and more compact.

[0067] For example, Figure 3 and Figure 5As shown, the first connecting hole 53 is a strip hole and extends along the height direction of the first supporting member 51, and the first connecting axis 23 is slidably matched with the first connecting hole 53; the mouse motherboard assembly also includes a third trigger switch 13 installed on the motherboard 10, and the third trigger switch 13 is opposite to the first connecting axis 23; when the mouse wheel 40 is pressed toward the motherboard 10, the first connecting axis 23 is used to move in a direction close to the motherboard 10 to press the third trigger switch 13.

[0068] The third trigger switch 13 is electrically connected to the mainboard 10. The third trigger switch 13 can be used as a start switch for a preset control circuit on the mainboard 10, so that when the third trigger switch 13 is pressed, the preset functions of the computer can be controlled, such as the functions of selecting all documents, copying or pasting text shortcut keys, etc. When the user presses the mouse wheel 40 toward the mainboard 10, the first connecting shaft 23 slides along the first connecting hole 53 toward the mainboard 10, and finally presses the third trigger switch 13, so that the user can indirectly press the third trigger switch 13. In this way, the button function of the mouse wheel 40 can be further increased.

[0069] The distance between the wheel body 41 and the first support member 51 and the distance between the wheel body 41 and the second support member 52 may be the same or different.

[0070] Specifically, Figure 5 As shown, the distance between the wheel body 41 and the first support member 51 is smaller than the distance between the wheel body 41 and the second support member 52. That is to say, the wheel body 41 is relatively closer to the first support member 51. Since the second connecting shaft 24 cannot slide, when the wheel body 41 is pressed toward the mainboard 10, the movement amplitude of the mounting frame 20 gradually decreases from the front end to the rear end; and when the wheel body 41 is close to the first support member 51, the wheel body 41 can be close to the front end of the mounting frame 20, so that when the wheel body 41 is pressed, the pressing force can be more transmitted to the front end of the mounting frame 20, so as to drive the front end of the mounting frame 20 and the first connecting shaft 23 to move toward the mainboard 10, so that the first connecting shaft 23 can more easily press the third trigger switch 13. As a result, when the user presses the third trigger switch 13 through the wheel body 41, it can be more convenient and labor-saving, so as to improve the use effect of the mouse.

[0071] The first pressing member 21 and the second pressing member 22 may be located in the middle of the mounting frame 20 , or may be located near the front end or the rear end of the mounting frame 20 .

[0072] In practical applications, such as Figure 5As shown, the first pressing member 21 and the second pressing member 22 are convexly arranged at one end of the mounting frame 20 close to the second supporting member 52, and the positions of the first trigger switch 11 and the second trigger switch 12 correspond to the first pressing member 21 and the second pressing member 22 respectively. When the wheel body 41 is pressed toward the mainboard 10, the movement amplitude of the mounting frame 20 gradually decreases from the front end to the rear end, that is, the rear end of the mounting frame 20 hardly changes position. Therefore, the first pressing member 21, the second pressing member 22, the first trigger switch 11 and the second trigger switch 12 are all arranged at a position close to the rear end of the mounting frame 20, so that the first pressing member 21 and the second pressing member 22 can maintain a stable position when the wheel body 41 is pressed toward the mainboard 10, thereby avoiding the first trigger switch 11 and the second trigger switch 12 from being accidentally touched, so as to improve the functional stability of the mouse.

[0073] Exemplarily, the first trigger switch 11, the second trigger switch 12 and the third trigger switch 13 are provided at the same height on the main board 10, so that the manufacturer can adjust the installation height of the mounting bracket 20 higher or lower based on the same height reference, ensuring that after each adjustment, the pressing process of the first trigger switch 11 and the second trigger switch 12 will not accidentally touch the third trigger switch 13, and the pressing process of the third trigger switch 13 will not accidentally touch the first trigger switch 11 and the second trigger switch 12, so as to ensure the functional stability of the mouse.

[0074] Each time the mounting bracket 20 swings, the first connecting shaft 23 will also rotate. If the side of the first connecting shaft 23 facing the third trigger switch 13 is a plane, the third trigger switch 13 may be accidentally triggered during the rotation process.

[0075] Specifically, a side of the first connecting shaft 23 facing the third trigger switch 13 is set to a convex arc surface, for example, it can be a cylindrical surface. The convex arc surface can make the distance between the first connecting shaft 23 and the third trigger switch 13 gradually decrease from both sides toward the axis center, and when the first connecting shaft 23 rotates, the distance between its axis center and the third trigger switch 13 remains unchanged; therefore, when the mounting frame 20 swings each time to make the first pressing member 21 press the first trigger switch 11, or the second pressing member 22 press the second trigger switch 12, the first connecting shaft 23 will not accidentally touch the third trigger switch 13 as the mounting frame 20 swings, so as to further ensure the functional stability of the mouse.

[0076] For example, Figure 1 , Figures 9 to 11 As shown, Fig. 9 It is a projection diagram of an embodiment of a state switching structure 60 in the present utility model; Fig.10 It is a projection diagram of another embodiment of the state switching structure 60 in the utility model; Fig.11 It is a structural diagram of an embodiment of the state switching structure 60 in the present utility model.

[0077] The mouse motherboard assembly also includes a state switching structure 60 installed on the mounting frame 20, and the state switching structure 60 is located between the mouse scroll wheel 40 and the second support member 52; the state switching structure 60 includes a self-locking snap switch 61 and an anti-rotation member 62, the self-locking snap switch 61 has a switchable switching state, and the anti-rotation member 62 is connected to the self-locking snap switch 61 to have a stop position and a disengagement position that are switched with the switching state switching of the self-locking snap switch 61; when the anti-rotation member 62 is in the stop position, the anti-rotation member 62 is used to abut against the mouse scroll wheel 40 to increase the resistance of the mouse scroll wheel 40; when the anti-rotation member 62 is in the disengagement position, the anti-rotation member 62 is used to disengage from the mouse scroll wheel 40 to reduce the resistance of the mouse scroll wheel 40.

[0078] The state switching structure 60 can make the mouse wheel 40 have a switchable frictionless mode and a friction mode. The self-locking buckle switch 61 is used for the user to switch the position of the anti-rotation member 62. Each time the self-locking buckle switch 61 is switched, the anti-rotation member 62 can be switched and locked between the stop position and the disengaged position. When the anti-rotation member 62 is in the stop position, it will abut against the mouse wheel 40 and cause resistance to the mouse wheel 40, so that the mouse wheel 40 will automatically stop under the action of the resistance every time the user turns the mouse wheel 40. When the anti-rotation member 62 is in the disengaged position, the mouse wheel 40 is not affected by the resistance of the anti-rotation member 62, so that the mouse wheel 40 will continue to roll every time the user turns the mouse wheel 40.

[0079] The user can switch the use effect of the mouse wheel 40 by himself through the state switching structure 60; when the mouse wheel 40 needs to be automatically stopped and have a friction feel, the self-locking buckle switch 61 can be operated to switch the anti-rotation member 62 to the stop position, so that the anti-rotation member 62 abuts against the mouse wheel 40 to increase the resistance of the mouse wheel 40; when the mouse wheel 40 needs to resume frictionless scrolling, the self-locking buckle switch 61 can be operated to switch the anti-rotation member 62 to the disengagement position, so that the anti-rotation member 62 disengages from the mouse wheel 40 to reduce the resistance of the mouse wheel 40. In this way, when using the mouse, the user can switch the friction mode and the frictionless mode of the mouse wheel 40 through the state switching structure 60, so that the mouse user who has just switched from a mechanical encoder to a grating encoder can freely switch the mode of the mouse wheel 40 during the adaptation period, thereby improving the use experience of the mouse.

[0080] Specifically, the state switching structure 60 further includes an elastic member 65 mounted on the mounting frame 20, one end of the elastic member 65 abuts against the anti-rotation member 62, so that when the anti-rotation member 62 is in the anti-rotation position, an elastic force is applied to the anti-rotation member 62 so that the anti-rotation member 62 abuts against the mouse wheel 40. In this way, the anti-rotation member 62 can generate sufficient resistance to the mouse wheel 40 at the anti-rotation position under the action of the elastic member 65, so as to ensure the self-stopping and friction feel effect of the mouse wheel 40.

[0081] The self-locking buckle switch 61 can be a toggle-type self-locking buckle or a push-button self-locking switch, which is not limited here.

[0082] In actual application, the self-locking buckle switch 61 is a button-type self-locking switch, so that when pressed, the anti-rotation member 62 switches between the anti-rotation position and the disengaged position. By pressing to switch the switch state of the self-locking buckle switch 61, that is, switching the position of the anti-rotation member 62, and thus switching the scrolling mode of the mouse wheel 40, the switching process of the scrolling mode of the mouse wheel 40 can be simplified, and the convenience of using the mouse can be further improved.

[0083] For example, Fig.11 As shown, the self-locking buckle switch 61 includes a fixed seat 63 and a pressing portion 64 movably connected to the fixed seat 63, and the pressing portion 64 is used to switch between a position close to the main board 10 and a position away from the main board 10 when pressed; the anti-rotation member 62 includes a transmission portion 622, a lever portion 623 and a stop portion 621, and the transmission portion 622 and the stop portion 621 are respectively connected to the two ends of the lever portion 623; the transmission portion 622 moves with the pressing portion 64, and the lever portion 623 is rotatably connected to the mounting frame 20 and abuts against the elastic member 65; when the pressing portion 64 approaches the main board 10, the lever portion 623 compresses the elastic member 65, and the stop portion 621 moves toward the disengaged position; when the pressing portion 64 is away from the main board 10, the elastic member 65 extends and pushes the lever portion 623, and the stop portion 621 moves toward the anti-rotation position.

[0084] When the mouse motherboard assembly is installed in the mouse housing, the pressing portion 64 is partially exposed from the mouse housing for the user to press. The pressing portion 64 has a first position and a second position, and the first position is closer to the motherboard 10 than the second position. Each time the pressing portion 64 is pressed into place, it switches and locks between the first position and the second position. Each time the pressing portion 64 switches positions, it drives the transmission portion 622 to move, and the transmission portion 622 then drives the stop portion 621 to move through the lever portion 623, so that the stop portion 621 can switch and lock between the stop position and the disengagement position. Due to the action of the lever portion 623, the movement direction of the stop portion 621 is opposite to the movement direction of the pressing portion 64, that is, when the pressing portion 64 is close to the motherboard 10, the stop portion 621 is away from the motherboard 10 and releases the contact with the mouse wheel 40; when the pressing portion 64 is away from the motherboard 10, the stop portion 621 is close to the motherboard 10 and contacts the mouse wheel 40. In this way, the anti-rotation member 62 can switch between the stop position and the disengagement position by rotating, so that the anti-rotation member 62 and the self-locking buckle switch 61 are connected at two locations, namely, the abutment or connection of the transmission part 622 and the rotatable connection of the lever part 623, thereby increasing the installation stability of the anti-rotation member 62.

[0085] The lever portion 623 is provided with an abutting portion, and one end of the elastic member 65 abuts against the abutting portion, so as to drive the stopper 621 to return to the anti-rotation position when the pressing portion 64 is away from the main board 10. The elastic member 65 may be a spring. When the pressing portion 64 is close to the main board 10, the stopper 621 moves to the disengaged position, and the abutting portion is pressed against the elastic member 65 to compress the elastic member 65; when the pressing portion 64 is away from the main board 10, the elastic member 65 recovers its deformation and releases kinetic energy, so as to drive the stopper 621 to return to the anti-rotation position by driving the abutting portion.

[0086] Specifically, Fig.11 As shown, the mounting frame 20 is provided with a first mounting groove 25 and a second mounting groove 26, the bottoms of the first mounting groove 25 and the second mounting groove 26 pass through the bottom of the mounting frame 20, the fixing seat 63 is partially installed in the first mounting groove 25, the elastic member 65 is partially installed in the second mounting groove 26, and the lever portion 623 abuts against the portion of the elastic member 65 extending out of the notch of the second mounting groove 26; the mouse motherboard 10 assembly also includes a bottom cover plate 70, and the bottom cover plate 70 covers the bottom openings of the first mounting groove 25 and the second mounting groove 26.

[0087] The bottom cover plate 70 is connected to the mounting frame 20 and covers the bottom openings of the first mounting groove 25 and the second mounting groove 26. The bottom cover plate 70 can support the fixing seat 63 to prevent the fixing seat 63 from falling out of the first mounting groove 25 when subjected to a pressing force. The elastic member 65 can be installed into the second mounting groove 26 from the bottom opening of the second mounting groove 26, and then the bottom cover plate 70 presses the elastic member 65 against the lever portion 623, thereby simplifying the installation process of the elastic member 65 and improving assembly efficiency.

[0088] For example, Fig.12 As shown, the mounting frame 20 is also provided with a third mounting groove, and a clamping hole 27 is opened at the bottom of the third mounting groove; the grating encoder 30 is installed in the third mounting groove, and the grating encoder 30 is provided with a fixed foot 36, and the fixed foot 36 is clamped and fixed with the clamping hole 27, so that the grating encoder 30 can be fixedly installed on the mounting frame 20.

[0089] Specifically, Fig.13 As shown, the rotating shaft 42 includes a first shaft body 421 and a second shaft body 422, the first shaft body 421 and the second shaft body 422 are respectively connected to the opposite sides of the wheel body along the axial direction, the first shaft body 421 is connected to the grating encoder 30, and the end wall of the second shaft body 422 away from one end of the wheel body is convexly provided with a positioning convex bump 423, and the mounting frame 20 is provided with a positioning portion 28, and the positioning portion 28 is opposite to the terminal end wall of the second shaft body 422, and the positioning portion 28 is used to abut against the positioning convex bump 423 to limit the axial displacement of the mouse wheel 40.

[0090] The side of the positioning convex bump 423 facing the positioning portion 28 can be set to a convex arc surface or a spherical surface. The grating encoder 30 and the positioning portion 28 can jointly limit the left and right deviation of the mouse wheel 40 along the axial direction to achieve the center positioning of the mouse wheel 40. By abutting the positioning convex bump 423 with the positioning portion 28, the specific shape of the second shaft body 422 can be simplified, and the contact area between the second shaft body 422 and the positioning portion 28 can be reduced to reduce the friction force on the rotating shaft 42, thereby ensuring the rotation effect of the mouse wheel 40.

[0091] The utility model also proposes a mouse, which includes a mouse motherboard assembly. The specific structure of the mouse motherboard assembly refers to the above embodiment. Since the mouse adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the mouse includes a shell, the mouse motherboard assembly is installed in the shell, and the mouse wheel 40 is partially exposed from the shell. The mouse may also include a switch button, which is connected to the top of the pressing portion 64 of the state switching structure 60, and the switch button is exposed from the shell, so that the user can switch the working mode of the mouse wheel 40 by pressing the switch button.

[0092] In the technical solution of the mouse motherboard assembly of the utility model, the mouse wheel 40 and the mouse encoder are mounted on the mounting frame 20, and the mounting frame 20 is swingably mounted above the motherboard 10, so that the mounting frame 20 can swing relative to the motherboard 10. When the user moves the mouse wheel 40 along the axial direction (left-right direction) of the mouse wheel 40, the mounting frame 20 can swing under the action of the moving force, so that the first pressing member 21 and the second pressing member 22 swing with the mounting frame 20, so that the first pressing member 21 can press the first trigger switch 11 during the swinging process, and the second pressing member 22 can press the second trigger switch 12 during the swinging process, so that the mouse wheel 40 adds two button functions on the basis of the original scrolling control function. Since the first pressing member 21 and the second pressing member 22 are protruding from the mounting frame 20, the force transmitted from the mouse wheel 40 to the first pressing member 21 and the second pressing member 22 is more stable and controllable, so that the movement stroke of the first pressing member 21 and the second pressing member 22 is easier to control, so that the first pressing member 21 and the second pressing member 22 can effectively press the first trigger switch 11 and the second trigger switch 12 each time, so as to improve the side-press control sensitivity of the mouse wheel 40, thereby improving the use effect of the mouse.
