State switching structure, mouse mainboard assembly and mouse

Abstract

The utility model discloses a state switching structure, a mouse mainboard assembly and a mouse. A user can automatically switch the using effect of a mouse wheel through the state switching structure. When the mouse roller needs to stop rotating automatically and has the friction hand feeling, the self-locking buckle switch can be operated to switch the rotation stopping piece to the rotation stopping position, so that the rotation stopping piece abuts against the mouse roller to increase the resistance borne by the mouse roller; and when the mouse roller needs to recover friction-free rolling, the self-locking buckle switch can be operated to switch the rotation resisting piece to the separation position, so that the rotation resisting piece is separated from the mouse roller to reduce the resistance borne by the mouse roller. Therefore, when a user uses the mouse, the friction mode and the friction-free mode of the mouse roller can be switched through the state switching structure, so that the mouse user just switching from a mechanical encoder to a grating encoder can freely switch the mode of the mouse roller in the adaptation period, and the use experience of the mouse is improved.

[0002] 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; the current mouse encoder is divided into two types: grating encoder and mechanical encoder.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel solutions, taking "A and / or B as an example", including solution A, or solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0043] With the popularization of computers, the mouse, an important input device at this stage, has the basic form of left and right buttons, and the middle scroll wheel realizes functions such as page turning. Among them, the mouse scroll wheel realizes the use function by connecting to the mouse encoder to drive it to rotate; the current mouse encoders are divided into two types: grating encoders and mechanical encoders. The grating encoder uses infrared rays to send and receive signals, and there is no substantial contact when the scroll wheel is working, so it has good stability and long life, but it has certain requirements for the mouse master programming. The other is the mechanical encoder, which is currently widely used on the mouse. Compared with the grating structure scroll wheel, the mechanical encoder has the advantages of good mechanical scale feel, simple structure, and easy master programming. For mouse users who have just switched from mechanical encoders to grating encoders, they will not be accustomed to the fact that the scroll wheel cannot stop rotating by itself and has no friction feel in the early stage, resulting in a poor user experience.

[0044] The utility model provides a state switching structure 40 for switching the rotation mode of the mouse wheel 30, aiming to solve the technical problem of how to improve the use effect of the mouse.

[0045] In the embodiment of the present utility model, Figures 1 to 4 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 It is a projection diagram of an embodiment of a mouse motherboard assembly of the utility model; Figure 4 It is a projection diagram of another embodiment of the mouse motherboard assembly of the utility model.

[0046] The state switching structure 40 includes: a self-locking snap switch 41, which has a switchable switch state; a rotation-blocking member 42, which is connected to the self-locking snap switch 41 to have a stop position and a disengagement position that are switched as the switch state of the self-locking snap switch 41 is switched; when the rotation-blocking member 42 is in the stop position, the rotation-blocking member 42 is used to abut against the mouse scroll wheel 30 to increase the resistance applied to the mouse scroll wheel 30; when the rotation-blocking member 42 is in the disengagement position, the rotation-blocking member 42 is used to disengage from the mouse scroll wheel 30 to reduce the resistance applied to the mouse scroll wheel 30.

[0047] The state switching structure 40 can make the mouse wheel 30 have a switchable frictionless mode and a friction mode. The self-locking buckle switch 41 is used for the user to switch the position of the anti-rotation member 42. Each time the self-locking buckle switch 41 is switched, the anti-rotation member 42 can be switched and locked between the stop position and the disengaged position. When the anti-rotation member 42 is in the stop position, it will abut against the mouse wheel 30 and cause resistance to the mouse wheel 30, so that the mouse wheel 30 will automatically stop rotating under the action of the resistance every time the user turns the mouse wheel 30. When the anti-rotation member 42 is in the disengaged position, the mouse wheel 30 is not affected by the resistance of the anti-rotation member 42, so that the mouse wheel 30 will continue to roll every time the user turns the mouse wheel 30.

[0048] The user can switch the use effect of the mouse wheel 30 by himself through the state switching structure 40; when the mouse wheel 30 needs to be automatically stopped and have a friction feel, the self-locking buckle switch 41 can be operated to switch the anti-rotation member 42 to the stop position, so that the anti-rotation member 42 abuts against the mouse wheel 30 to increase the resistance of the mouse wheel 30; when the mouse wheel 30 needs to resume frictionless scrolling, the self-locking buckle switch 41 can be operated to switch the anti-rotation member 42 to the disengagement position, so that the anti-rotation member 42 disengages from the mouse wheel 30 to reduce the resistance of the mouse wheel 30. In this way, when using the mouse, the user can switch the friction mode and the frictionless mode of the mouse wheel 30 through the state switching structure 40, 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 30 during the adaptation period, thereby improving the use experience of the mouse.

[0049] For example, Figure 5 As shown, Figure 5 The schematic cross-sectional view of an embodiment of the mouse motherboard assembly of the utility model. The state switching structure 40 further includes an elastic member 45 installed on the self-locking buckle switch 41, one end of the elastic member 45 abuts against the anti-rotation member 42, so that when the anti-rotation member 42 is in the anti-rotation position, an elastic force is applied to the anti-rotation member 42 so that the anti-rotation member 42 abuts against the mouse wheel 30. In this way, the anti-rotation member 42 can generate sufficient resistance to the mouse wheel 30 at the anti-rotation position under the action of the elastic member 45, so as to ensure the self-stopping and friction feel effect of the mouse wheel 30.

[0050] The self-locking buckle switch 41 can be a toggle-type self-locking buckle or a push-button self-locking switch, which is not limited here.

[0051] Specifically, the self-locking buckle switch 41 is a button-type self-locking switch, so that when pressed, the anti-rotation member 42 switches between the anti-rotation position and the disengaged position. By pressing to switch the switch state of the self-locking buckle switch 41, that is, switching the position of the anti-rotation member 42, and thus switching the scrolling mode of the mouse wheel 30, the switching process of the scrolling mode of the mouse wheel 30 can be simplified, and the convenience of using the mouse can be further improved.

[0052] For example, Figures 5 to 7 As shown, Figure 6 It is a structural diagram of an embodiment of a state switching structure 40 in the present utility model; Figure 7 It is a structural diagram of another embodiment of the state switching structure 40 in the present invention.

[0053] The anti-rotation member 42 includes a transmission part 422, a lever part 423 and a stop part 421, and the transmission part 422 and the stop part 421 are respectively connected to the two ends of the lever part 423; the self-locking buckle switch 41 includes a fixed seat 43 and a pressing part 44 that can move relative to the fixed seat 43, the transmission part 422 moves with the pressing part 44, and the lever part 423 is rotatably connected to the fixed seat 43; when the pressing part 44 approaches the fixed seat 43, the stop part 421 moves toward the disengagement position; when the pressing part 44 moves away from the fixed seat 43, the stop part 421 moves toward the anti-rotation position.

[0054] When the mouse motherboard assembly is installed in the mouse housing, the pressing portion 44 is partially exposed from the mouse housing for the user to press. The pressing portion 44 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 44 is pressed into place, it switches and locks between the first position and the second position. Each time the pressing portion 44 switches positions, it drives the transmission portion 422 to move, and the transmission portion 422 then drives the stop portion 421 to move through the lever portion 423, so that the stop portion 421 can switch and lock between the stop position and the disengagement position. Due to the action of the lever portion 423, the movement direction of the stop portion 421 is opposite to the movement direction of the pressing portion 44, that is, when the pressing portion 44 is close to the motherboard 10, the stop portion 421 is away from the motherboard 10 and releases the contact with the mouse wheel 30; when the pressing portion 44 is away from the motherboard 10, the stop portion 421 is close to the motherboard 10 and contacts the mouse wheel 30. In this way, the anti-rotation member 42 can switch between the stop position and the disengagement position by rotating, so that the anti-rotation member 42 and the self-locking buckle switch 41 are connected at two locations, namely, the abutment or connection of the transmission part 422 and the rotatable connection of the lever part 423, thereby increasing the installation stability of the anti-rotation member 42.

[0055] The rotation axis 32 of the lever portion 423 may extend along the length direction thereof or may be perpendicular to the length direction thereof.

[0056] Specifically, Figure 6 and Figure 7As shown, the rotation axis 32 of the lever part 423 extends along its length direction, the fixing seat 43 is provided with a matching piece 431, the matching piece 431 is provided with a matching groove, and the lever part 423 is rotatably matched with the matching groove. The stopper 421 can be parallel to the lever part 423, and the stopper 421 and the lever part 423 are connected by a first connecting part, so that the contact area between the stopper 421 and the mouse wheel 30 can be increased to improve the contact stability, thereby maintaining the resistance stability to the mouse wheel 30. The transmission part 422 can also be parallel to the lever part 423, and the transmission part 422 and the lever part 423 are connected by a second connecting part, so that the connection or contact area between the transmission part 422 and the pressing part 44 can be increased to improve the stability of the motion transmission between the pressing part 44 and the transmission part 422.

[0057] The number of the matching pieces 431 may be two or more, and the multiple matching pieces 431 are arranged at intervals along the length direction of the lever portion 423 , so as to increase the matching positions with the lever portion 423 and improve the rotation stability of the lever portion 423 .

[0058] For example, Figure 6 and Figure 7 As shown, the lever portion 423 and the matching groove are detachably matched; the pressing portion 44 is provided with a pushing rib 441, and the pushing rib 441 abuts against the transmission portion 422 to push the transmission portion 422 when the pressing portion 44 is close to the fixing seat 43. In this way, when assembling the state switching structure 40, if the position of the stopper 421 does not match the position of the groove 33 provided on the wheel body 31, the corresponding anti-rotation member 42 can be replaced by disassembling the anti-rotation member 42, thereby improving the assembly convenience of the state switching structure 40. The number of the pushing ribs 441 can be two or more, and the plurality of pushing ribs 441 are arranged at intervals along the length direction of the transmission portion 422, so that the abutment position of the transmission portion 422 can be increased to improve the pushing stability of the transmission portion 422.

[0059] Specifically, Figures 5 to 7As shown, in combination with the embodiment of the elastic member 45, the lever portion 423 is provided with an abutting portion 424, and one end of the elastic member 45 abuts against the abutting portion 424, so as to drive the stopper 421 to return to the anti-rotation position when the pressing portion 44 is away from the fixing seat 43. The elastic member 45 can be a spring. When the pressing portion 44 approaches the fixing seat 43, the stopper 421 moves to the disengaged position, and the abutting portion 424 is pressed against the elastic member 45 to compress the elastic member 45; when the pressing portion 44 is away from the fixing seat 43, the elastic member 45 recovers the deformation and releases the kinetic energy, so as to drive the stopper 421 to return to the anti-rotation position by driving the abutting portion 424. The fixing seat 43 can be provided with an installation groove, and the elastic member 45 is partially installed in the installation groove, and one end of the elastic member 45 abuts against the groove bottom of the installation groove, and the other end extends out of the installation groove and abuts against the abutting portion 424, so that the installation stability of the elastic member 45 can be improved.

[0060] In practical applications, such as Figure 6 and Figure 7 As shown, the pressing portion 44 is provided with a guide rib 442, and the fixing seat 43 is provided with a guide rail 432, and the guide rib 442 and the guide rail 432 can be slidably matched. The guide rib 442 extends along the movement direction of the pressing portion 44, and the shape of the guide rail 432 is adapted to the guide rib 442. The guide rib 442 and the guide rail 432 are slidably matched, so that the movement process of the pressing portion 44 when being pressed can be more stable, so as to improve the structural stability of the state switching structure 40.

[0061] The state switching structure 40 and the mainboard 10 can be fixed by plugging or snapping.

[0062] Exemplarily, the main board 10 is provided with a card hole, and the self-locking card switch 41 is provided with a card fastener 45, and the card fastener 45 is used to be detachably engaged with the card hole on the mouse main board 10. When producing and processing the main board 10, a card hole can be reserved on the main board 10 first. In the subsequent production and processing of the mouse main board assembly, if the state switching structure 40 needs to be installed, the card fastener 45 of the self-locking card switch 41 can be directly engaged with the card hole reserved on the main board 10; if the state switching structure 40 does not need to be installed, the main board 10 can also be directly used in the mouse main board assembly with a grating encoder without a state switching structure 40. In other words, by reserving a card hole on the main board 10, the same main board 10 can be applied to the production and processing of a mouse with a state switching structure 40 and a mouse without a state switching structure 40, thereby improving the production and processing efficiency of the mouse and reducing the material preparation cost.

[0063] Specifically, Figure 8 As shown, Figure 8It is a cross-sectional schematic diagram of an embodiment of the self-locking buckle switch in the utility model. The self-locking buckle switch 41 also includes a self-locking switch 46 installed on the fixing seat 43, the self-locking switch 46 is provided with a buckle position, and the pressing portion 44 is provided with an elastic hook, and the elastic hook is engaged with the buckle position. After the pressing portion 44 is pressed into place each time, the self-locking switch 46 can be driven to switch between the open state and the closed state. In this way, the pressing portion 44 can be switched between the open and closed states by pressing within the elastic travel range of the self-locking switch 46. The self-locking switch 46 can be a push-type self-locking switch, a button-type self-locking switch, or a key-type self-locking switch. The self-locking switch 46 is a standard part, so that the acquisition method of the self-locking switch 46 can be simplified to reduce the production and processing difficulty of the state switching structure 40. The height and shape of the pressing portion 44 can be adjusted according to the actual application scenario to adapt to mice of different shapes and sizes.

[0064] The utility model also proposes a mouse motherboard assembly, which includes a motherboard 10, a grating encoder 20, a mouse wheel 30 and a state switching structure 40. The specific structure of the state switching structure 40 refers to the above embodiment. Since the mouse motherboard assembly 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 grating encoder 20 and the state switching structure 40 are installed on the motherboard 10, the mouse wheel 20 includes a wheel body 31 and a rotating shaft 32, and the rotating shaft 32 is connected to the grating encoder 20. The anti-rotation member 42 of the state switching structure 40 abuts against the mouse wheel 30 when it is in the stop position, and is separated from the mouse wheel 30 when it is in the disengaged position.

[0065] In this embodiment, the main board 10 is a circuit board, specifically a hard circuit board, and the main board 10 can provide power and transmit signals to the grating encoder 20. The grating encoder 30 is a bearing type grating encoder.

[0066] Specifically, Fig. 9 and Fig.10 As shown, Fig. 9 It is a structural exploded diagram of an embodiment of a grating encoder 20 in the present utility model; Fig.10 It is a structural explosion diagram of another embodiment of the grating encoder 20 in the utility model.

[0067] The grating encoder 20 includes a housing 21, a grating component and a circuit board 25. The housing 21 is provided with an installation cavity and a connecting hole 211. The installation cavity is communicated with the connecting hole 211, and the connecting hole 211 is connected to the rotating shaft 32. The grating component can be rotatably installed in the installation cavity. The grating component includes a rotating cylinder 221 and a grating disk 222 sleeved on the outside of the rotating cylinder 221. The rotating cylinder 221 is coaxially arranged with the connecting hole 211 for connection with the rotating shaft 32 of the mouse wheel 30. The grating disk 222 has a plurality of light-transmitting grooves 223 distributed at intervals along the circumferential direction. The circuit board 25 is installed in the installation cavity. The circuit board 25 is electrically connected with a light emitter and a light receiver. The circuit board 25 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 221 rotates, the grating disk 222 is driven by the rotating cylinder 221 so that the grating disk 222 blocks or exposes the optical path.

[0068] By manually turning the mouse wheel 30, a force is generated to drive the grating component to rotate (because the rotating shaft 32 of the mouse wheel 30 is plugged into the rotating cylinder 221). The circuit board 25 is electrically connected to the main board 10 to achieve a conductive state, and then the rotating shaft 32 of the mouse wheel 30 is inserted into the rotating cylinder 221 from the connecting hole 211. At this time, the mouse wheel 30 and the grating component are in a coaxial state. Therefore, when the mouse wheel 30 is turned by the user, the mouse wheel 30 can drive the grating disk 222 connected thereto to rotate synchronously through the rotating shaft 32. At this time, the grating disk 222 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 25 can detect that the optical signal of the optical path changes first, and then identify the rolling state of the mouse wheel 30, so that the mouse can complete the corresponding command input work according to the rolling of the mouse wheel 30.

[0069] 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 222", and the second receiving unit corresponds to "counterclockwise rotation of the grating disk 222". When the mouse wheel 30 is driven by the user to rotate counterclockwise, the mouse wheel 30 can drive the grating disk 222 connected thereto to rotate synchronously. At this time, the grating disk 222 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 25 can detect the change in the optical signal of the second optical path, and then identify the counterclockwise rotation of the mouse wheel 30, so that the mouse can complete the corresponding command input work according to the counterclockwise rolling of the mouse wheel 30.

[0070] The material of the shell 21 can be plastic, metal, or a combination of plastic and metal. The shell 21 made of plastic is relatively light and is conducive to reducing the overall volume of the mouse, which is convenient for users to use. The shell 21 made of metal has relatively strong strength and is conducive to extending the service life of the shell 21. Therefore, in some embodiments, part of the material can be metal and part of the material can be plastic.

[0071] The optical transmitter and the optical receiver can be fixed to the circuit board 25 by welding, so as to realize the electrical connection while realizing the mechanical connection. Of course, in some embodiments, the optical transmitter and the optical receiver can also be fixedly connected to the circuit board 25 by plugging.

[0072] In practical applications, such as Figures 2 to 5 As shown, the grating encoder 20 is located on one side of the wheel body 31 in the axial direction, and a groove 33 is provided on the other side surface of the wheel body 31 in the axial direction. The groove 33 is arranged in an annular manner on the rotating shaft 32, and a plurality of mating teeth 331 are arranged on the groove wall of the groove 33. The plurality of mating teeth 331 are arranged along the circumference of the rotating shaft 32; the anti-rotation member 42 includes a stop portion 421, and when the stop portion 421 is in the anti-rotation position, it can be reset to enter the interval between two adjacent mating teeth 331 to increase the resistance applied to the mating teeth 331.

[0073] The grating encoder 20 is located on one side of the wheel body 31 in the axial direction, and the groove 33 is opened on the surface of the other side of the wheel body 31 in the axial direction, so that the grating encoder 20 can be prevented from causing obstruction to the contact between the anti-rotation member 42 and the matching tooth 331. The matching tooth 331 is arranged on the groove wall of the groove 33, so as to avoid protruding additional structures on the wheel body 31 to prevent affecting the overall appearance and installation of the mouse wheel 30. While preventing the user from being affected, it can also effectively and compactly cooperate with the state switching structure 40 to switch the working mode. When the state switching structure 40 switches the mouse wheel 30 to the friction mode, the matching tooth 331 needs to squeeze the stopper 421 when passing through the stopper 421 to overcome the resistance caused by the stopper 421. The squeezing force will squeeze the stopper 421 out of the gap between two adjacent matching teeth 331. The resistance caused by the stopper 421 to the mating tooth 331 will be fed back to the user through the mouse wheel 30, so that the user can perceive the mechanical paragraph feel through touch. Combined with the change of the page on the display screen as the mouse wheel 30 rotates, the user can obtain the change amplitude of the page each time the mouse wheel 30 pauses, which is convenient for the user to control the page change through the mouse wheel 30 more accurately, thereby improving the use effect of the mouse and improving the user experience.

[0074] For example, Fig.11 and Fig.12 As shown, Fig.11This is a schematic structural diagram of an embodiment of a mouse of the utility model; Fig.12 It is a cross-sectional schematic diagram of an embodiment of a mouse of the present utility model.

[0075] 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 30 is partially exposed from the shell. The mouse may also include a switch button 50, the switch button 50 is connected to the top of the pressing portion 44 of the state switching structure 40, and the switch button 50 is exposed from the shell, so that the user can switch the working mode of the mouse wheel 30 by pressing the switch button 50.

[0076] In the technical solution of the mouse mainboard assembly of the utility model, the user can switch the use effect of the mouse wheel 30 by himself through the state switching structure 40; when the mouse wheel 30 needs to have friction and paragraph feel, the self-locking buckle switch 41 can be operated to switch the anti-rotation member 42 to the stop position, so that the anti-rotation member 42 abuts against the mouse wheel 30 to increase the resistance of the mouse wheel 30; when the mouse wheel 30 needs to resume frictionless scrolling, the self-locking buckle switch 41 can be operated to switch the anti-rotation member 42 to the disengagement position, so that the anti-rotation member 42 disengages from the mouse wheel 30 to reduce the resistance of the mouse wheel 30. In this way, after the state switching structure 40 is added to the mouse using the shuttle scroll wheel, the mouse wheel 30 has both the paragraph friction mode and the frictionless mode, and can be switched arbitrarily through the state switching structure 40. The user can freely select the state mode of the mouse wheel 30 according to his own usage habits. For the mouse user who converts from the traditional mechanical encoder to the grating encoder, the mode of the mouse wheel 30 can be freely switched during the adaptation period, thereby improving the use experience of the mouse.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
