[0002] The present application relates to the field of keyboards, and in particular to a keyboard and electronic equipment. Background Art

[0003] With the development of science and technology and the demand of the electronic equipment market, keyboards, as the main way to input information, are increasingly attracting the attention of manufacturers. In a traditional keyboard, all the keys move horizontally up and down during the tapping process, and each row of keys has the same tilt angle, which can easily cause wrist fatigue after long-term use. In another traditional keyboard, although the tapping angles of each row of keys are different, and the long-term use feels good, the unreasonable structural setting causes a waste of space, and it cannot be used on thin tablets or laptops, and the appearance is untidy. Therefore, it is urgent to provide a keyboard that is ergonomic, has a good long-term use feel, and can improve the utilization rate of keyboard space.

[0004] Summary of the Invention

[0005] The purpose of the present application is to provide a keyboard and an electronic device that are ergonomic, have a good feel for long-term use, and can improve the utilization rate of keyboard space.

[0006] In a first aspect, the present application provides a keyboard. The keyboard includes a housing, a circuit board, and a plurality of keys, wherein the circuit board is mounted on the housing, and the plurality of keys are mounted on the circuit board, wherein the plurality of keys each include an unpressed state and a triggered state;

[0007] The plurality of buttons include a first button and a second button, wherein a first central axis of the first button is perpendicular to a top surface of the first button and passes through a center of the top surface of the first button, and a second central axis of the second button is perpendicular to a top surface of the second button and passes through a center of the top surface of the second button;

[0008] When both the first button and the second button are in the unpressed state, the included angle between the first central axis and the second central axis is a, and a satisfies 0° ≤ a < M1; where 0° < M1 ≤ 10°. Exemplarily, M1 can be equal to 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9° or 10°, etc. For example, 0° ≤ a < 3°.

[0009] When both the first button and the second button are in the triggered state, the included angle between the first central axis and the second central axis is b, and b satisfies: b satisfies: b ≥ M1. For example, b ≥ 3°.

[0010] It can be understood that by setting that when both the first button and the second button are in the unpressed state, a satisfies: 0° ≤ a < M1; where 0° < M1 ≤ 10°, so that when both the first button and the second button are in the unpressed state, the first central axis of the first button and the second central axis of the second button are substantially parallel. At this time, when both the first button and the second button are in the unpressed state, the top surface of the first button and the top surface of the second button are substantially parallel, and the orientations of the top surface of the first button and the top surface of the second button are substantially the same. In this way, compared with the scheme where the top surface of the first button and the top surface of the second button have different orientations when both the first button and the second button are in the unpressed state, in this embodiment, since the orientations of the top surface of the first button and the top surface of the second button are substantially the same when both the first button and the second button are in the unpressed state, the occupied spaces of the first button and the second button in the Z-axis direction are relatively consistent. The first button and the second button are not easily wasted in the Z-axis direction due to the unevenness of their respective top surfaces, which is beneficial to the thin design of the keyboard.

[0011] In addition, since the orientations of the top surface of the first button and the top surface of the second button are substantially the same when both the first button and the second button are in the unpressed state, the appearance consistency of the first button and the second button is better, and the appearance of the keyboard is cleaner, which is beneficial to improving the user experience of the keyboard.

[0012] It can be understood that, by setting it so that when the first button and the second button are both in the triggered state, b satisfies: b≥M1, so that when the first button and the second button are both in the triggered state, the first central axis of the first button and the second central axis of the second button are intersecting. At this time, when the first button and the second button are both in the triggered state, the top surface of the first button and the top surface of the second button are intersecting (that is, they are not parallel), that is, the top surface of the first button and the top surface of the second button are in different directions. In this way, compared to the solution in which the top surface of the first button and the top surface of the second button face the same direction when the first button and the second button are both in the triggered state, in this embodiment, since the top surface of the first button and the top surface of the second button face in different directions, the first button and the second button can not only meet the user's tapping feel at different positions, but also solve the problem of fatigue of the user's wrist due to the same degree of bending at different positions. At this time, the setting method of the first button and the second button can meet ergonomic theory, and the user experience is better.

[0013] In one possible implementation, when both the first and second buttons are not pressed, the top surface of the first button is flush with the top surface of the second button. In this way, the space occupied by the first and second buttons in the Z-axis direction is relatively consistent, thereby facilitating a thinner keyboard.

[0014] In a possible implementation, the central axis of the circuit board is perpendicular to the top surface of the circuit board and passes through the center of the top surface of the circuit board, and the top surface of the circuit board is the surface of the circuit board facing the key;

[0015] When both the first button and the second button are in the trigger state, the top surface of the second button is tilted toward the first button, and the angle between the first central axis and the central axis is A1, and the angle between the second central axis and the central axis is A2, and A1 and A2 satisfy: A2>A1.

[0016] It can be understood that by setting the top surface of the second button to be inclined toward the direction close to the first button when both the first button and the second button are in the triggered state, and A2>A1, the user's wrist is not easily fatigued when tapping different positions on the keyboard, thereby greatly improving the user experience.

[0017] In one possible implementation, A1 and A2 satisfy the following conditions: 0° ≤ A1 < 3°, and A2 ≥ 3°. This ensures that A2 > A1. Furthermore, because A1 satisfies the following conditions: 0° ≤ A1 < 3°, the first central axis of the first key is approximately parallel to the central axis of the circuit board. This prevents the first key from occupying significant space along the Z axis, thereby improving keyboard space utilization.

[0018] In a possible implementation, the multiple keys further include a third key, and the third key is spaced apart from both the first key and the second key;

[0019] The third central axis of the third key is perpendicular to the top surface of the third key and passes through the center of the top surface of the third key;

[0020] When both the first key and the third key are in the unpressed state, the included angle between the third central axis and the first central axis is c, and c satisfies: 0° ≤ c < M2, where 0° < M2 ≤ 10°. Exemplarily, M2 can be equal to 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9° or 10°, etc. For example, 0° ≤ c < 3°;

[0021] When both the first key and the third key are in the triggered state, the included angle between the third central axis and the first central axis is d, and d satisfies: d ≥ M2. For example, d ≥ 3°.

[0022] It can be understood that by setting that when both the first key and the third key are in the unpressed state, c satisfies: 0° ≤ c < M2, where 0° < M2 ≤ 10°, so that when both the first key and the third key are in the unpressed state, the first central axis of the first key and the third central axis of the third key are substantially parallel. At this time, when both the first key and the third key are in the unpressed state, the top surface of the first key and the top surface of the third key are substantially parallel, that is, the orientations of the top surface of the first key and the top surface of the third key are substantially the same. In addition, since when both the first key and the second key are in the unpressed state, the orientations of the top surface of the first key and the top surface of the second key are substantially the same. Thus, when the first key, the second key and the third key are all in the unpressed state, the orientations of the top surface of the first key, the top surface of the second key and the top surface of the third key are substantially the same. The occupied spaces of the first key, the second key and the third key in the Z-axis direction are relatively consistent. The first key, the second key and the third key are not likely to cause space waste in the Z-axis direction due to the unevenness of their respective top surfaces, which is beneficial to the thin design of the keyboard.

[0023] In addition, since when the first key, the second key and the third key are all in the unpressed state, the orientations of the top surface of the first key, the top surface of the second key and the top surface of the third key are substantially the same, the appearance consistency of the first key, the second key and the third key is relatively good, and the appearance of the keyboard is relatively neat, which is beneficial to improving the user experience of the keyboard.

[0024] It can be understood that, by setting it so that when the first button and the third button are both in the triggered state, d satisfies: d≥M2, so that when the first button and the third button are both in the triggered state, the first central axis of the first button and the third central axis of the third button are intersected. At this time, when the first button and the third button are both in the triggered state, the top surface of the first button and the top surface of the third button are intersected (that is, they are not parallel), that is, the top surface of the first button and the top surface of the third button are in different directions. The first button and the third button can not only satisfy the user's tapping feel at different positions, but also solve the problem of fatigue of the user's wrist due to the same degree of bending at different positions. The setting method of the first button and the third button can meet the theory of ergonomics, and the user experience is better.

[0025] For example, when the first button and the third button are both in an unpressed state, the top surface of the first button is flush with the top surface of the third button. In this way, the space occupied by the first button and the third button in the Z-axis direction is relatively consistent, which is conducive to the thinning of the keyboard.

[0026] In a possible implementation, the third button is located on a side of the second button away from the first button;

[0027] When the first button, the second button and the third button are all in the triggered state, the top surface of the third button is inclined toward the direction close to the first button, and b and d satisfy: d>b.

[0028] It can be understood that because b and d satisfy: d > b, the inclination angle of the third button is greater than the inclination angle of the second button. In this case, when the first button is close to the user and the third button is set away from the user, or when the first button is far from the user and the third button is set close to the user, the first, second, and third buttons can both meet the user's typing feel at different distances and prevent wrist fatigue caused by the same degree of bending at different distances. The configuration of the first and third buttons meets ergonomic principles and provides a better user experience.

[0029] In a possible implementation, the central axis of the circuit board is perpendicular to the top surface of the circuit board and passes through the center of the top surface of the circuit board, and the top surface of the circuit board is the surface of the circuit board facing the key;

[0030] When both the second and third buttons are in the triggered state, the angle between the second central axis and the central axis is A2, and the angle between the third central axis and the central axis is A3. A2 and A3 satisfy: A3 > A2. Thus, the inclination angle of the third button is greater than the inclination angle of the second button. In this case, when the first button is close to the user and the third button is set away from the user, or when the first button is set away from the user and the third button is set close to the user, the first, second, and third buttons can satisfy the user's tapping feel at different distances while also solving the problem of wrist fatigue caused by the same degree of bending at different distances. The configuration of the first and third buttons meets ergonomic principles and provides a better user experience.

[0031] In a possible implementation, the third button is located on a side of the first button away from the second button;

[0032] When the first button and the third button are both in the trigger state, the top surface of the third button is tilted toward the first button, the angle between the first central axis and the central axis is A1, and the angle between the third central axis and the central axis is A3. A1 and A3 satisfy: A3>A1.

[0033] It can be understood that because A1 and A3 satisfy the condition A3 > A1, the inclination angle of the third button is greater than that of the first button. In this case, when the third button is positioned closer to the user or farther away from the user, the first, second, and third buttons can satisfy the user's typing feel at different distances while also addressing wrist fatigue caused by the same degree of bending at different distances. This arrangement of the first and third buttons meets ergonomic principles and provides a better user experience.

[0034] In a possible implementation, the first button includes a first keycap, a first connecting member, and a second connecting member;

[0035] The first connecting member includes a first rotating end and a first movable end, the first rotating end of the first connecting member is rotatably connected to the circuit board, and the first movable end of the first connecting member is movably connected to the first keycap; the second connecting member includes a second rotating end and a second movable end, the second rotating end of the second connecting member is rotatably connected to the circuit board, and the second movable end of the second connecting member is movably connected to the first keycap;

[0036] The first rotating end of the first connecting member includes a first gear portion, and the second rotating end of the second connecting member includes a second gear portion, and the first gear portion of the first connecting member is meshed with the second gear portion of the second connecting member, wherein the pitch circle diameter of the first gear portion of the first connecting member is a first diameter, and the pitch circle diameter of the second gear portion of the second connecting member is a second diameter, when the first diameter and the second diameter are not equal, the ratio of the maximum value to the minimum value of the first diameter and the second diameter is a first value, and when the first diameter and the second diameter are equal, the ratio of the first diameter to the second diameter is the first value;

[0037] The second key includes a second keycap, a third connecting member, and a fourth connecting member, the third connecting member includes a first rotating end and a first movable end, the first rotating end of the third connecting member is rotatably connected to the circuit board, the first movable end of the third connecting member is movably connected to the second keycap, the fourth connecting member includes a second rotating end and a second movable end, the second rotating end of the fourth connecting member is rotatably connected to the circuit board, and the second movable end of the fourth connecting member is movably connected to the second keycap;

[0038] The first rotating end of the third connecting member includes a first gear portion, and the second rotating end of the fourth connecting member includes a second gear portion. The first gear portion of the third connecting member is meshed with the second gear portion of the fourth connecting member. The diameter of the pitch circle of the first gear portion of the third connecting member is a third diameter, and the diameter of the pitch circle of the second gear portion of the fourth connecting member is a fourth diameter. The third diameter is not equal to the fourth diameter. The ratio of the maximum value to the minimum value of the third diameter and the fourth diameter is a second value, and the second value is greater than the first value.

[0039] It is understood that the pitch circle diameter of the first gear portion of the first connector of the first button is the first diameter. The pitch circle diameter of the second gear portion of the second connector of the first button is the second diameter. When the first and second diameters are unequal, the ratio of the maximum to minimum values ​​of the first and second diameters is the first value. For example, if the first diameter is 2 mm and the second diameter is 5 mm, the first diameter is the minimum value and the second diameter is the maximum value. In this case, the first value is the ratio of 5 to 2, or 2.5. When the first and second diameters are equal, the ratio of the first to second diameters is the first value. This embodiment is described using the example of the first and second diameters being equal. Furthermore, the pitch circle diameter of the first gear portion of the third connector of the second button is the third diameter. The pitch circle diameter of the second gear portion of the fourth connector is the fourth diameter. If the third and fourth diameters are unequal, the ratio of the maximum to minimum values ​​of the third and fourth diameters is the second value. For example, if the third diameter is 2 mm and the fourth diameter is 6 mm, the third diameter is the minimum value and the fourth diameter is the maximum value. At this time, the second value is a ratio of 6 to 2, that is, 3. In this embodiment, the second value is greater than the first value.

[0040] It is understood that by setting the second value to be greater than the first value, when both the first and second buttons are in the triggered state, the first and second buttons have different inclination angles relative to the circuit board, with the second button having a larger inclination angle than the first button. This increases the angle b between the first central axis of the first button and the second central axis of the second button, thereby achieving a different orientation of the top surface of the first button and the top surface of the second button. In this way, when both the first and second buttons are in the triggered state, the arrangement of the first and second buttons meets ergonomic principles and provides a better user experience. It is understood that the greater the difference between the second value and the first value, the greater the inclination angle of the second button relative to the first button. This increases the angle b between the first central axis of the first button and the second central axis of the second button. The smaller the difference between the second value and the first value, the closer the inclination angles of the first and second buttons become. This decreases the angle b between the first central axis of the first button and the second central axis of the second button.

[0041] In a possible implementation, the first diameter is equal to the second diameter, and the third diameter is smaller than the fourth diameter.

[0042] In a possible implementation, the first connecting member is provided with a first avoidance hole, and the first avoidance hole divides the first gear portion of the first rotating end of the first connecting member into a first sub-gear portion and a second sub-gear portion;

[0043] The second connecting member is provided with a second avoidance hole, and the second avoidance hole divides the second gear portion of the second rotating end of the second connecting member into a first sub-gear portion and a second sub-gear portion;

[0044] The first avoidance hole of the first connecting member is communicated with the second avoidance hole of the second connecting member, the first sub-gear portion of the first connecting member is meshed with the first sub-gear portion of the second connecting member, and the second sub-gear portion of the first connecting member is meshed with the second sub-gear portion of the second connecting member.

[0045] It can be understood that the space enclosed by the first avoidance hole and the second avoidance hole can be used to provide avoidance space for other components of the first key or other components of the keyboard, thereby avoiding interference between other components of the first key, other components of the keyboard and the first connecting member and the second connecting member.

[0046] In one possible implementation, the first sub-gear portion of the first connecting member includes a first tooth and a second tooth, the second tooth of the first connecting member is located on a side of the first tooth of the first connecting member close to the second sub-gear portion of the first connecting member, and the first sub-gear portion of the second connecting member includes a first tooth and a second tooth, the second tooth of the second connecting member is located on a side of the first tooth of the second connecting member close to the second sub-gear portion of the second connecting member;

[0047] The first tooth of the first connecting member is engaged with the first tooth of the second connecting member, the second tooth of the first connecting member is engaged with the second tooth of the second connecting member, and the line connecting the first tooth and the second tooth of the first connecting member and the line connecting the first tooth and the second tooth of the second connecting member are arranged to intersect.

[0048] In a possible implementation, the first sub-gear portion of the first connecting member includes a first tooth, and the first sub-gear portion of the second connecting member includes a first tooth and a second tooth that are spaced apart and arranged opposite to each other;

[0049] The first tooth of the first connecting member is located between the first tooth and the second tooth of the second connecting member.

[0050] It is understood that by arranging the line connecting the first and second teeth of the first connecting member and the line connecting the first and second teeth of the second connecting member to intersect, the first gear portion of the first connecting member and the second gear portion of the second connecting member are arranged in a staggered structure. In this way, the thickness of the first gear portion of the first connecting member and the second gear portion of the second connecting member is smaller in the Z-axis direction, thereby facilitating a thinner configuration of the first button.

[0051] In a possible implementation, the first connecting member includes a first connecting section, and the first connecting section of the first connecting member connects the first rotating end of the first connecting member and the first movable end of the first connecting member;

[0052] The second connecting member includes a second connecting section, and the second connecting section of the second connecting member is connected to the second rotating end of the second connecting member and the second movable end of the second connecting member;

[0053] The first button further includes a first elastic member, the first elastic member is connected to the first connecting section of the first connecting member and the second connecting section of the second connecting member, and the first elastic member is in a stretched state.

[0054] It is understandable that the first elastic member can be used to apply a pulling force to the first connecting member and the second connecting member. When the first button switches from an unpressed state to a triggered state, the first elastic member can apply a force along the positive direction of the Z axis to the first keycap through the first connecting member and the second connecting member. At this time, in the process of pressing the first keycap to move along the negative direction of the Z axis, it is necessary to first overcome the force applied by the first elastic member to the first keycap, which is conducive to improving the user's feel in the process of pressing the first keycap. Even when the first button is in an unpressed state, the first elastic member can be in a stretched state, and the first elastic member can apply a force along the positive direction of the Z axis to the first keycap through the first connecting member and the second connecting member. At this time, when the user accidentally touches the first keycap, the first keycap will not immediately move along the negative direction of the Z axis and squeeze the trigger end of the circuit board to cause the circuit board to generate an electrical signal.

[0055] In a possible implementation, the first center line of the first elastic member passes through the center of the first elastic member and is parallel to the length extension direction of the first elastic member;

[0056] When the first button is in a triggered state, the first center line is set at an angle to the top surface of the circuit board, and the top surface of the circuit board is the surface of the circuit board facing the button.

[0057] It is understood that because the first centerline of the first elastic member is not parallel to the top surface of the circuit board, the elastic force exerted by the first elastic member on the first and second connecting members can generate a force component in the positive direction of the Z-axis. In this case, this force component can cause the first rotating end of the first connecting member to rotate relative to the first and second fixing bases, and the second rotating end of the second connecting member to rotate relative to the first and second fixing bases, thereby switching the first button from the triggered state to the unpressed state.

[0058] In a possible implementation, the first movable end of the first connecting member is slidably connected to the first keycap and is relatively rotatable.

[0059] The center of rotation of the first connecting member relative to the circuit board is a first rotation center, the center of rotation of the first connecting member relative to the first keycap is a second rotation center, the distance between the first rotation center and the bottom surface of the circuit board is a first height H1, and the distance between the second rotation center and the bottom surface of the circuit board is a second height H2, wherein the bottom surface of the circuit board is the surface of the circuit board facing away from the key;

[0060] When the first button is in the trigger state, H1 and H2 meet the following conditions: H1 <H2。

[0061] It can be understood that when the first button is in the triggered state, the first height H1 is less than the second height H2, that is, H1 and H2 satisfy: H1 < H2. At this time, the elastic force exerted by the first elastic member on the first connecting member can generate a component force in the positive direction of the Z axis. This component force can cause the first rotating end of the first connecting member to rotate relative to the first fixed seat and the second fixed seat. Since the first gear portion of the first rotating portion of the first connecting member meshes with the second gear portion of the second rotating portion of the second connecting member, the first rotating end of the first connecting member and the second rotating portion of the second connecting member can rotate synchronously, that is, the second rotating end of the second connecting member can rotate relative to the first fixed seat and the second fixed seat, so that the first button can be switched from the triggered state to the unpressed state.

[0062] In a possible implementation, the keyboard includes a first fixed seat and a second fixed seat, and the first fixed seat and the second fixed seat are fixedly arranged on the circuit board at intervals;

[0063] The first rotating end of the first connecting member includes a first rotating portion and a second rotating portion. The first rotating portion of the first connecting member protrudes from the first end surface of the first gear portion of the first connecting member, and the second rotating portion of the first connecting member protrudes from the second end surface of the first gear portion of the first connecting member. The first end surface and the second end surface of the first gear portion of the first connecting member are arranged back to back;

[0064] The first rotating portion of the first rotating end of the first connecting member is rotatably connected to the first fixed seat, and the second rotating portion of the first rotating end of the first connecting member is rotatably connected to the second fixed seat.

[0065] It can be understood that the first connecting member can be rotatably connected to the circuit board through the first fixed seat and the second fixed seat. The second connecting member can be rotatably connected to the circuit board through the first fixed seat and the second fixed seat. Among them, the first connecting member and the second connecting member can be first assembled to the first fixed seat and the second fixed seat, and then the first fixed seat and the second fixed seat are fixed on the circuit board. In this way, the assembly process between the first connecting member, the second connecting member and the circuit board is simpler.

[0066] In a possible implementation, the first rotating end of the first connecting member includes a first stop portion. The first stop portion of the first connecting member protrudes from the first end surface of the first gear portion of the first connecting member, and the first fixed seat is provided with a first stop groove;

[0067] When the first button is in the unpressed state, at least a part of the first stop portion of the first connecting member is located in the first stop groove and abuts against the bottom wall of the first stop groove;

[0068] When the first button is in the triggered state, the first stop portion is separated from the bottom wall of the first stop groove.

[0069] It can be understood that the bottom wall of the first stopping groove can be used to limit the first connecting member from continuing to rotate relative to the first fixing seat when the first button is in an unpressed state.

[0070] In a possible implementation, the first stop portion of the first connecting member is located on a side of the first rotating portion of the first connecting member away from the first movable end of the first connecting member.

[0071] In one possible implementation, the circuit board includes a plurality of trigger terminals;

[0072] The keyboard also includes multiple triggering members, which are located between multiple keys and multiple triggering ends in a one-to-one correspondence. When the key is in the trigger state, the key squeezes the triggering end of the circuit board through the triggering member, and the circuit board generates an electrical signal.

[0073] It can be understood that, compared with the solution in which the button directly presses the trigger end of the circuit board, the button of this embodiment presses the trigger end of the circuit board through the trigger member, which can simplify the structure of the button.

[0074] In one possible implementation, multiple triggering members are fixed to multiple triggering ends in a one-to-one correspondence. This ensures that the triggering members accurately trigger the triggering ends of the circuit board, thus preventing the triggering members from failing to accurately press the triggering ends when a key is pressed.

[0075] In a possible implementation, the trigger member is an elastic member, and when the button is in the trigger state, the trigger member is in a compressed state.

[0076] It is understood that when the first key switches from the triggered state to the unpressed state, since the first keycap is no longer subjected to pressing force, the elastic force exerted by the triggering member on the first keycap can cause the first keycap to move along the positive direction of the Z axis. At this time, the first keycap can exert a force on the first connecting member and the second connecting member, thereby causing the first rotating end of the first connecting member to rotate relative to the first and second fixing seats, and the second rotating end of the second connecting member to rotate relative to the first and second fixing seats. In this way, the first key can switch from the triggered state to the unpressed state.

[0077] In a second aspect, the present application provides an electronic device comprising a display device and the keyboard according to the first aspect, wherein the keyboard is communicatively connected to the display device.

[0078] It is understandable that a keyboard that is ergonomic, feels good for long-term use, and can improve keyboard space utilization makes electronic devices provide a better user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0117] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0118] In the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," "connected," and "connected" should be understood broadly. For example, "connected" can mean removable or non-removable; directly or indirectly through an intermediary; electrically or mechanically. "Fixed connection" refers to a connection in which the relative positional relationship remains unchanged after connection. "Moveable connection" refers to a connection in which the relative positional relationship can be changed after connection. "Rotational connection" refers to a connection in which the connection allows relative rotation. "Sliding connection" refers to a connection in which the connection allows relative sliding. Furthermore, two components forming an integrated structure through an integral molding process mean that during the formation of one of the two components, that component is connected to the other without requiring further processing (such as bonding, welding, snap-fit ​​connection, or screw connection) to connect the two components. To ensure that the basic parameters of a gear are standardized and deterministic, a circle must be specified as a reference for calculation in gear calculations. This circle is called the pitch circle. The diameter of the pitch circle is equal to the module multiplied by the number of teeth. The module is equal to the ratio of the tooth pitch to π.

[0119] The directional terms mentioned in the embodiments of the present application, such as "top", "bottom", "inside", "outside", "left", "right", "distal end", "proximal end", etc., are only used to refer to the directions in the drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the embodiments of the present application. For those skilled in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0120] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0121] FIG1 is a schematic structural diagram of an electronic device 1000 provided in accordance with an embodiment of the present application.

[0122] As shown in FIG1 , the present application provides an electronic device 1000. The electronic device 1000 may be a device with a keyboard, such as a notebook computer or a personal computer.

[0123] For example, electronic device 1000 includes a keyboard 100 and a display device 200. Keyboard 100 can serve as an input device for display device 200. Display device 200 can be a device with a display function, such as a display screen, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), or a mobile phone.

[0124] It is understandable that the keyboard 100 can be communicatively connected to the display device 200. In this way, the user can input instructions to the display device 200 through the keyboard 100, so that the display device 200 displays according to the input instructions. Among them, the communication connection includes a wired communication connection and a wireless communication connection. "Wired communication connection" can be understood as a physical contact and electrical conduction between multiple components; it can also be understood as a form in which multiple components in a circuit structure are connected through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit signals. "Wireless communication connection" can be understood as multiple components achieving signal transmission in an airless / non-contact manner. For example, multiple components can use short-range communication technology (for example, Bluetooth, wireless local area network (WiFi, Wireless Fidelity) or short-range communication (NFC, Near Field Communication), etc.).

[0125] For ease of description, the thickness direction of the keyboard 100 is defined as the Z-axis, and the width direction of the keyboard 100 is defined as the Y-axis. The direction perpendicular to the Y-axis and the Z-axis is defined as the X-axis, that is, the length direction of the keyboard 100 is defined as the X-axis. It is understood that the coordinate system of the keyboard 100 can also be flexibly configured according to specific needs.

[0126] FIG. 2 is a partially exploded schematic diagram of the keyboard 100 shown in FIG. 1 in one embodiment.

[0127] As shown in Figures 1 and 2, the keyboard 100 includes a housing 1, a circuit board 2, and a plurality of keys 3. It is understood that Figures 1 and 2 only schematically illustrate a certain number of keys 3, and the specific number, size, etc. of the keys 3 are not specifically limited in this application.

[0128] In one embodiment, the housing 1 includes a top panel 11 and a bottom panel 12 disposed oppositely, a distal side panel 13 (also referred to as a first side panel 13) and a proximal side panel 14 (also referred to as a second side panel 14) disposed oppositely, and a left side panel 15 (also referred to as a third side panel 15) and a right side panel 16 (also referred to as a fourth side panel 16) disposed oppositely. The distal side panel 13 and the proximal side panel 14 are connected between the top panel 11 and the bottom panel 12. The left side panel 15 and the right side panel 16 are connected between the top panel 11 and the bottom panel 12, and further connected between the distal side panel 13 and the proximal side panel 14. It will be understood that the distal side panel 13 of the housing 1 may be the side panel of the housing 1 that is away from the user when the user is using the keyboard 100. The proximal side panel 14 of the housing 1 may be the side panel of the housing 1 that is closer to the user when the user is using the keyboard 100. The left side panel 15 of the housing 1 may be the side panel of the housing 1 that is closer to the user's left hand when the user is using the keyboard 100. The right side panel 16 of the housing 1 may be the side panel of the housing 1 close to the right hand of the user when the user is using the keyboard 100 .

[0129] The top plate 11 , the bottom plate 12 , the distal side plate 13 , the proximal side plate 14 , the left side plate 15 and the right side plate 16 of the housing 1 may enclose an accommodation space 17 .

[0130] As shown in Figures 1 and 2, the top plate 11 of the housing 1 is provided with a plurality of through holes 18. Through holes 18 communicate with the accommodation space 17. It is understood that this application does not impose specific limitations on the size, shape, or arrangement of through holes 18. Furthermore, the size and shape of each through hole 18 may be the same or different.

[0131] It is understandable that, although the foregoing describes a specific structure of the housing 1 , in other embodiments, the housing 1 may also adopt other structures, which is not specifically limited in this application.

[0132] As shown in Figure 2, the circuit board 2 includes a plurality of trigger terminals 21. Figure 2 schematically shows the trigger terminal 21 through a dotted box. The trigger terminal 21 is used to generate an electrical signal when the button 3 is pressed, and the information or instruction composed of the electrical signal can be transmitted to the display device 200. It is understandable that this application does not make specific restrictions on the size, shape, and arrangement of the trigger terminal 21. Specifically, it can be flexibly set according to needs. In addition, the connection method between the button 3 and the trigger terminal 21 will be described in detail below in conjunction with the relevant drawings, and will not be repeated here.

[0133] FIG3 is a partial cross-sectional view of the keyboard 100 shown in FIG1 taken along line AA according to an embodiment of the present invention.

[0134] Referring to Figure 3 , in conjunction with Figures 1 and 2 , the circuit board 2 is located within the housing space 17 of the housing 1 and is mounted on the housing 1. For example, the circuit board 2 can be attached to the top plate 11 of the housing 1 by welding, screwing, bonding, or other fixing methods. In other embodiments, the circuit board 2 can also be fixed to the bottom plate 12 of the housing 1.

[0135] In one embodiment, the multiple triggering ends 21 of the circuit board 2 can be arranged in a one-to-one correspondence with the multiple through holes 18 of the housing 1 .

[0136] Referring to Figure 3 , in conjunction with Figures 1 and 2 , multiple buttons 3 are exemplarily mounted on the circuit board 2 . A portion of the buttons 3 may be located within the through-hole 18 , while a portion may be located outside the housing 1 . In other embodiments, the buttons 3 may extend from the accommodating space 17 through the through-hole 18 to the exterior of the housing 1 . In this case, a portion of the buttons 3 may be located within the accommodating space 17 , a portion within the through-hole 18 , and a portion outside the housing 1 .

[0137] It is understandable that multiple buttons 3 include an unpressed state (also called a starting state) and a triggered state (also called a terminal state). Among them, Figures 1 to 3 schematically show the structure of the button 3 in the unpressed state. When the button 3 is in the unpressed state, the button 3 does not trigger the trigger end 21 of the circuit board 2, and the circuit board 2 does not generate an electrical signal. When the button 3 is in the triggered state, the button 3 triggers the trigger end 21 of the circuit board 2, and the circuit board 2 can generate an electrical signal. It is understandable that the button 3 can directly press the trigger end 21 of the circuit board 2, or press the trigger end 21 of the circuit board 2 through other components. Specifically, this application does not limit it.

[0138] It is understandable that the button 3 may also include an intermediate state. The intermediate state of the button 3 may be any state between the unpressed state and the triggered state of the button 3.

[0139] As shown in FIGS. 1 to 3, the multiple keys 3 include a first key 3a and a second key 3b. It can be understood that FIGS. 1 to 3 illustrate that the first key 3a and the second key 3b are arranged along the positive Y-axis direction. In other embodiments, the first key 3a and the second key 3b can be arranged arbitrarily on the X-Y plane. For example, the first key 3a and the second key 3b can be arranged along the negative Y-axis direction, the positive X-axis direction, or the negative X-axis direction, etc. Specifically, the present application does not make a limitation.

[0140] FIG. 4 is a partial structural schematic diagram of the keyboard 100 shown in FIG. 1 in an embodiment.

[0141] As shown in FIG. 4, the first key 3a includes a top surface 30a. The top surface 30a of the first key 3a is the surface of the first key 3a facing away from the circuit board 2. The top surface 30a of the first key 3a can be a flat surface or a curved surface. The first key 3a includes a first central axis L1. The first central axis L1 of the first key 3a can be perpendicular to the top surface 30a of the first key 3a and pass through the center of the top surface 30a of the first key 3a.

[0142] As shown in FIG. 4, the second key 3b includes a top surface 30b. The top surface 30b of the second key 3b is the surface of the second key 3b facing away from the circuit board 2. The top surface 30b of the second key 3b can be a flat surface or a curved surface. The second key 3b includes a second central axis L2. The second central axis L2 of the second key 3b can be perpendicular to the top surface 30b of the second key 3b and pass through the center of the top surface 30b of the second key 3b.

[0143] As shown in FIG. 4, when both the first key 3a and the second key 3b are in the un-pressed state, the included angle between the first central axis L1 of the first key 3a and the second central axis L2 of the second key 3b is a. a satisfies: 0° ≤ a < M1; where, 0° < M1 ≤ 10°. Exemplarily, M1 can be equal to 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, or 10°, etc. For example, 0° ≤ a < 3°. It can be understood that, in order to clearly illustrate the included angle a, FIG. 4 shows the first central axis L1 and the second central axis L2 moved to the top of the first key 3a and the second key 3b and combined to form the included angle a. For similar settings that may appear hereinafter, the explanations here can be referred to. Specifically, it will not be elaborated hereinafter. In addition, the included angle a between the first central axis L1 and the second central axis L2 refers to the magnitude and does not include the direction. The relevant angles hereinafter can also be referred to the explanations here. Specifically, it will not be elaborated hereinafter.

[0144] It can be understood that when the first button 3a and the second button 3b are both in the unpressed state, a satisfies: 0°≤a<M1; where 0°<M1≤10°, so that when the first button 3a and the second button 3b are both in the unpressed state, the first central axis L1 of the first button 3a and the second central axis L2 of the second button 3b are substantially parallel. At this time, when the first button 3a and the second button 3b are both in the unpressed state, the top surface 30a of the first button 3a and the top surface 30b of the second button 3b are substantially parallel, and the orientations of the top surface 30a of the first button 3a and the top surface 30b of the second button 3b are substantially the same. In this way, compared with the solution where the top surface 30a of the first button 3a and the top surface 30b of the second button 3b have different orientations when the first button 3a and the second button 3b are both in the unpressed state, in this embodiment, since the top surface 30a of the first button 3a and the top surface 30b of the second button 3b have substantially the same orientation when the first button 3a and the second button 3b are both in the unpressed state, the occupied space of the first button 3a and the second button 3b in the Z-axis direction is relatively consistent. The first button 3a and the second button 3b are not easily wasted in the Z-axis direction due to the unevenness of their respective top surfaces, which is beneficial to the thin design of the keyboard 100.

[0145] In addition, since the top surface 30a of the first button 3a and the top surface 30b of the second button 3b have substantially the same orientation when the first button 3a and the second button 3b are both in the unpressed state, the appearance consistency of the first button 3a and the second button 3b is better, and the appearance of the keyboard 100 is cleaner, which is beneficial to improving the user experience of the keyboard 100.

[0146] Exemplarily, when the first button 3a and the second button 3b are both in the unpressed state, the top surface 30a of the first button 3a and the top surface 30b of the second button 3b are flush. In this way, the occupied space of the first button 3a and the second button 3b in the Z-axis direction is relatively consistent, which is beneficial to the thin design of the keyboard 100.

[0147] Figure 5 is a partial structural schematic diagram of an embodiment when the keyboard 100 shown in Figure 4 is in a triggered state.

[0148] As shown in Figure 5, when the first button 3a and the second button 3b are both in the triggered state, the included angle between the first central axis L1 of the first button 3a and the second central axis L2 of the second button 3b is b. b satisfies: b≥M1. For example, b≥3°.

[0149] It can be understood that by setting b to satisfy b ≥ M1 when both the first button 3a and the second button 3b are in the triggered state, the first central axis L1 of the first button 3a and the second central axis L2 of the second button 3b intersect when both the first button 3a and the second button 3b are in the triggered state. In this case, when both the first button 3a and the second button 3b are in the triggered state, the top surface 30a of the first button 3a and the top surface 30b of the second button 3b intersect (i.e., are not parallel), that is, the top surface 30a of the first button 3a and the top surface 30b of the second button 3b face different directions. Thus, compared to a solution in which the top surfaces 30a of the first button 3a and the top surfaces 30b of the second button 3b face the same direction when both the first button 3a and the second button 3b are in the triggered state, in this embodiment, because the top surfaces 30a of the first button 3a and the top surfaces 30b of the second button 3b face different directions, the first button 3a and the second button 3b can satisfy the user's tapping feel at different positions and solve the problem of wrist fatigue caused by the same degree of bending at different positions. In this way, the arrangement of the first button 3a and the second button 3b meets ergonomic theory and provides a better user experience.

[0150] It is understandable that when both the first button 3a and the second button 3b are in the triggered state, the orientations of the top surface 30a of the first button 3a and the top surface 30b of the second button 3b can be set in various ways, which will be described in detail below with reference to the relevant drawings.

[0151] FIG6 is a partially exploded schematic diagram of an embodiment of the keyboard 100 shown in FIG1 in a triggered state.

[0152] 6 , the second button 3b is located between the first button 3a and the distal side plate 13 of the housing 1. In other words, compared to the first button 3a, the second button 3b is located closer to the distal side plate 13 of the housing 1.

[0153] In one embodiment, when both the first button 3a and the second button 3b are in the triggered state, the top surface 30b of the second button 3b is tilted toward the first button 3a, and the angle A2 between the second central axis L2 of the second button 3b and the central axis L0 of the circuit board 2 is greater than the angle A1 between the first central axis L1 of the first button 3a and the central axis L0 of the circuit board 2, i.e., A2 > A1. The central axis L0 of the circuit board 2 is perpendicular to the top surface 22 of the circuit board 2 and passes through the center of the top surface 22 of the circuit board 2. The top surface 22 of the circuit board 2 is the surface of the circuit board 2 facing the button 3.

[0154] It can be understood that by setting the top surface 30b of the second button 3b to be inclined toward the direction close to the first button 3a when the first button 3a and the second button 3b are in the triggered state, and A2>A1, the user is not likely to get tired when typing the key 3 away from the user on the keyboard 100, thereby greatly improving the user experience.

[0155] In one embodiment, A1 can satisfy the following: 0° ≤ A1 < 3°. A2 can satisfy the following: A2 ≥ 3°. This ensures that A2 > A1. Furthermore, because A1 satisfies the following: 0° ≤ A1 < 3°, the first central axis L1 of the first key 3a is substantially parallel to the central axis L0 of the circuit board 2. In this case, the first key 3a does not occupy much space in the Z-axis direction, thereby improving the space utilization of the keyboard 100.

[0156] In other embodiments, A1 may also satisfy: A1 ≥ 3°, which can be flexibly set according to needs.

[0157] FIG7 is a partially exploded schematic diagram of another embodiment of the keyboard 100 shown in FIG1 in a triggered state.

[0158] 7 , the second button 3b is located between the first button 3a and the proximal side plate 14 of the housing 1. In other words, compared to the first button 3a, the second button 3b is disposed closer to the proximal side plate 14 of the housing 1.

[0159] In one embodiment, when the first button 3a and the second button 3b are both in the triggered state, the top surface 30b of the second button 3b is inclined toward the first button 3a, and the angle A2 between the second central axis L2 of the second button 3b and the central axis L0 of the circuit board 2 is greater than the angle A1 between the first central axis L1 of the first button 3a and the central axis L0 of the circuit board 2, that is, A2>A1.

[0160] It can be understood that by setting that when the first button 3a and the second button 3b are both in the triggered state, the top surface 30b of the second button 3b is inclined toward the direction close to the first button 3a, and A2>A1, the user's wrist is not easily fatigued when typing the key 3 close to the user on the keyboard 100, thereby greatly improving the user experience.

[0161] In one embodiment, A1 can satisfy: 0° ≤ A1 < 3°. A2 can satisfy: A2 ≥ 3°. In this way, on the one hand, it can ensure that A2 > A1; on the other hand, since A1 can satisfy: 0° ≤ A1 < 3°, the first central axis L1 of the first key 3a is arranged substantially parallel to the central axis L0 of the circuit board 2. At this time, the first key 3a does not occupy much space in the Z-axis direction, which is beneficial to improving the space utilization rate of the keyboard 100.

[0162] In other embodiments, A1 can also satisfy: A1 ≥ 3°. Specifically, it can be flexibly set according to requirements.

[0163] FIG. 8 is a partial structural schematic diagram of the keyboard 100 shown in FIG. 1 in another embodiment.

[0164] As shown in FIG. 8, exemplarily, the plurality of keys 3 may further include a third key 3c. The third key 3c is spaced apart from both the first key 3a and the second key 3b.

[0165] As shown in FIG. 8, the third key 3c includes a top surface 30c. The top surface 30c of the third key 3c is the surface of the third key 3c facing away from the circuit board 2. The top surface 30c of the third key 3c can be a flat surface or a curved surface. The third key 3c includes a third central axis L3. The third central axis L3 of the third key 3c is perpendicular to the top surface 30c of the third key 3c and passes through the center of the top surface 30c of the third key 3c.

[0166] As shown in FIG. 8, when both the first key 3a and the third key 3c are in the unpressed state, the included angle between the third central axis L3 of the third key 3c and the first central axis L1 of the first key 3a is c. c satisfies: 0° ≤ c < M2, where 0° < M2 ≤ 10°. Exemplarily, M2 can be equal to 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9° or 10°, etc. For example, 0° ≤ c < 3.

[0167] It can be understood that when the first key 3a and the third key 3c are both in the non-pressed state, c satisfies: 0°≤c<M2, where 0°<M2≤10°. Thus, when the first key 3a and the third key 3c are both in the non-pressed state, the first central axis L1 of the first key 3a and the third central axis L3 of the third key 3c are substantially parallel. At this time, when the first key 3a and the third key 3c are both in the non-pressed state, the top surface 30a of the first key 3a and the top surface 30c of the third key 3c are substantially parallel, that is, the orientations of the top surface 30a of the first key 3a and the top surface 30c of the third key 3c are substantially the same. In addition, since when the first key 3a and the second key 3b are both in the non-pressed state, the orientations of the top surface 30a of the first key 3a and the top surface 30b of the second key 3b are substantially the same. In this way, when the first key 3a, the second key 3b, and the third key 3c are all in the non-pressed state, the orientations of the top surface 30a of the first key 3a, the top surface 30b of the second key 3b, and the top surface 30c of the third key 3c are substantially the same. The occupied spaces of the first key 3a, the second key 3b, and the third key 3c in the Z-axis direction are relatively consistent. The first key 3a, the second key 3b, and the third key 3c are not easily wasted in the space in the Z-axis direction due to the unevenness of their respective top surfaces, which is beneficial to the thin-type setting of the keyboard 100.

[0168] In addition, since when the first key 3a, the second key 3b, and the third key 3c are all in the non-pressed state, the orientations of the top surface 30a of the first key 3a, the top surface 30b of the second key 3b, and the top surface 30c of the third key 3c are substantially the same, the appearance consistency of the first key 3a, the second key 3b, and the third key 3c is relatively good, and the appearance of the keyboard 100 is cleaner and more beautiful, which is beneficial to improving the user experience of the keyboard 100.

[0169] Exemplarily, when the first key 3a and the third key 3c are both in the non-pressed state, the top surface 30a of the first key 3a and the top surface 30c of the third key 3c are flush. In this way, the occupied spaces of the first key 3a and the third key 3c in the Z-axis direction are relatively consistent, which is beneficial to the thin-type setting of the keyboard 100.

[0170] Figure 9 is a partial structural schematic diagram of an implementation manner when the keyboard 100 shown in Figure 8 is in a triggered state.

[0171] As shown in Figure 9, when the first key 3a and the third key 3c are both in the triggered state, the included angle between the first central axis L1 of the first key 3a and the third central axis L3 of the third key 3c is d, and d satisfies: d≥M2. For example, d≥3°.

[0172] It can be understood that by setting it so that when the first button 3a and the third button 3c are both in the triggered state, d satisfies: d≥M2, so that when the first button 3a and the third button 3c are both in the triggered state, the first central axis L1 of the first button 3a and the third central axis L3 of the third button 3c are intersected. At this time, when the first button 3a and the third button 3c are both in the triggered state, the top surface 30a of the first button 3a and the top surface 30c of the third button 3c are intersected (that is, they are not parallel), that is, the top surface 30a of the first button 3a and the top surface 30c of the third button 3c are in different directions. The first button 3a and the third button 3c can not only satisfy the user's tapping feel at different positions, but also solve the problem of fatigue of the user's wrist due to the same degree of bending at different positions. The setting method of the first button 3a and the third button 3c can meet ergonomic theory and provide better user experience.

[0173] It can be understood that when the first button 3a, the second button 3b and the third button 3c are all in the trigger state, the angle d between the third central axis L3 and the first central axis L1 is greater than the angle b between the second central axis L2 and the first central axis L1, that is, b and d satisfy: d>b.

[0174] It is understood that when the second button 3b and the third button 3c are both in the triggered state, the angle e between the second central axis L2 of the second button 3b and the third central axis L3 of the third button 3c can satisfy the following conditions: e ≥ 3° or 0° ≤ e < 3°. This application does not impose any specific limitations.

[0175] The following will describe in detail several arrangements of the third button 3c, the first button 3a and the second button 3b with reference to the relevant drawings.

[0176] FIG10 is a partially exploded schematic diagram of another embodiment of the keyboard 100 shown in FIG1 in a triggered state.

[0177] As shown in Figure 10, the third button 3c is located on the side of the second button 3b that is farther from the first button 3a. That is, the second button 3b is located between the first button 3a and the third button 3c. Furthermore, the third button 3c is located between the second button 3b and the distal side panel 13 of the housing 1. In other words, the third button 3c is located closer to the distal side panel 13 of the housing 1 than the first button 3a and the second button 3b.

[0178] As shown in Figure 10, when the first, second, and third buttons 3a, 3b, and 3c are all in the triggered state, the top surfaces 30b, 30c, and 30b of the second and third buttons 3b, 3c are tilted toward the first button 3a. Furthermore, the angle A2 between the second central axis L2 of the second button 3b and the central axis L0 of the circuit board 2 is greater than the angle A1 between the first central axis L1 of the first button 3a and the central axis L0 of the circuit board 2, i.e., A2 > A1. Furthermore, the angle A3 between the third central axis L3 of the third button 3c and the central axis L0 of the circuit board 2 is greater than the angle A2 between the second central axis L2 of the second button 3b and the central axis L0 of the circuit board 2, i.e., A3 > A2. This reduces wrist fatigue when a user presses the third button 3c, significantly improving the user experience. The arrangement of the first, second, and third buttons 3a, 3b, and 3c meets ergonomic principles and provides a superior user experience.

[0179] FIG11 is a partially exploded schematic diagram of another embodiment of the keyboard 100 shown in FIG1 in a triggered state.

[0180] As shown in Figure 11, the first button 3a is located between the second button 3b and the third button 3c. The second button 3b is located between the first button 3a and the distal side panel 13 of the housing 1. The third button 3c is located between the first button 3a and the proximal side panel 14 of the housing 1. In other words, the second button 3b is located closer to the distal side panel 13 of the housing 1 than the first button 3a. The third button 3c is located closer to the proximal side panel 14 of the housing 1 than the first button 3a.

[0181] In one embodiment, when the first button 3a and the second button 3b are both in the triggered state, the top surface 30b of the second button 3b is inclined toward the first button 3a, and the angle A2 between the second central axis L2 of the second button 3b and the central axis L0 of the circuit board 2 is greater than the angle A1 between the first central axis L1 of the first button 3a and the central axis L0 of the circuit board 2, that is, A2>A1.

[0182] It can be understood that by setting the top surface 30b of the second button 3b to be inclined toward the first button 3a when both the first button 3a and the second button 3b are in the triggered state, and A2>A1, the user's wrist is not easily fatigued when typing the second button 3b away from the user on the keyboard 100, thereby greatly improving the user experience.

[0183] In one embodiment, when the first button 3a and the third button 3c are both in the triggered state, the top surface 30c of the third button 3c is inclined toward the direction close to the first button 3a, and the angle A3 between the third central axis L3 of the third button 3c and the central axis L0 of the circuit board 2 is greater than the angle A1 between the first central axis L1 of the first button 3a and the central axis L0 of the circuit board 2, that is, A3>A1.

[0184] It can be understood that by setting that when the first button 3a and the third button 3c are in the triggered state, the top surface 30c of the third button 3c is inclined toward the direction close to the first button 3a, and A3>A1, so that when the user taps the third button 3c close to the user on the keyboard 100, the wrist will not become fatigued due to the large degree of bending, thereby greatly improving the user experience.

[0185] In this embodiment, the angle A3 between the third central axis L3 of the third button 3c and the central axis L0 of the circuit board 2 can be greater than, less than, or equal to the angle A2 between the second central axis L2 of the second button 3b and the central axis L0 of the circuit board 2. This application does not limit this specifically.

[0186] It is understandable that when both the second button 3b and the third button 3c are in the triggered state, the top surface 30b of the second button 3b tilts toward the first button 3a, and the top surface 30c of the third button 3c tilts toward the first button 3a, causing the top surface 30b of the second button 3b and the top surface 30c of the third button 3c to face different directions. In this way, the interaction between the second button 3b and the third button 3c can satisfy the user's tapping feel at different positions and solve the problem of wrist fatigue caused by the same degree of bending at different positions. The configuration of the first button 3a and the third button 3c can meet ergonomic principles and provide a better user experience.

[0187] It is understood that the multiple keys 3 may further include a fourth key, a fifth key, ..., and an Mth key. Here, M ≥ 4. Relative to the first key 3a, the Mth key may be positioned closer to the distal side panel 13 or closer to the proximal side panel 14. For example, the Mth key may be positioned similarly to the third key 3c. Specifically, the Mth key may be positioned flexibly according to needs. In this way, more keys 3 of the keyboard 100 can be positioned at different angles.

[0188] Fig. 12 is a partially exploded view of another embodiment of the keyboard 100 shown in Fig. 1. Fig. 13 is a partially cross-sectional view of another embodiment of the keyboard 100 shown in Fig. 1 taken along line AA.

[0189] As shown in Figures 12 and 13, the keyboard 100 further includes a plurality of trigger members 5. The trigger members 5 can be elastic members, such as rubber caps, springs, or springs. In other embodiments, the trigger members 5 can also be structural members of other forms.

[0190] The trigger members 5 are positioned between the buttons 3 and the trigger ends 21 in a one-to-one correspondence. For example, one trigger member 5 is positioned between one button 3 and one trigger end 21. It is understood that by pressing the button 3, the button 3 compresses the trigger member 5, causing the trigger member 5 to deform and compress the trigger end 21 of the circuit board 2, thereby causing the circuit board 2 to generate an electrical signal.

[0191] In one embodiment, multiple trigger members 5 are fixed to the multiple trigger ends 21 on the circuit board 2 in a one-to-one correspondence. This ensures that the trigger members 5 accurately trigger the trigger ends 21 of the circuit board 2, thereby preventing the trigger members 5 from failing to accurately press the trigger ends 21 when the button 3 presses the trigger members 5. In other embodiments, multiple trigger members 5 may also be fixed to the button 3, and the multiple trigger members 5 are arranged opposite the multiple trigger ends 21 in a one-to-one correspondence. When the button 3 is pressed, the button 3 can drive the trigger members 5 to move, and the trigger members 5 press the trigger ends 21 of the circuit board 2, causing the circuit board 2 to generate an electrical signal.

[0192] As shown in Figures 12 and 13, illustratively, the keyboard 100 further includes a reinforcement plate 4. The reinforcement plate 4 can be a steel sheet, an aluminum sheet, a titanium alloy sheet, or the like.

[0193] For example, the reinforcing plate 4 can be fixed to the surface of the circuit board 2 facing the key 3. The reinforcing plate 4 can be used to increase the strength of the circuit board 2. The reinforcing plate 4 is provided with a plurality of avoidance holes 41. The avoidance holes 41 are arranged in a one-to-one correspondence with the plurality of trigger ends 21. The trigger member 5 can be exposed relative to the reinforcing plate 4 through the avoidance holes 41. In other embodiments, multiple trigger members 5 can also be fixed to the reinforcing plate 4, and the multiple trigger members 5 can be arranged in a one-to-one correspondence relative to the plurality of trigger ends 21 through the avoidance holes 41.

[0194] In other embodiments, the reinforcing plate 4 can also be fixed to the surface of the circuit board 2 facing away from the button 3. In this case, the reinforcing plate 4 no longer interferes with the trigger 5. The reinforcing plate 4 does not need to be provided with the avoidance hole 41.

[0195] Fig. 14A is a partial structural diagram of another embodiment of the keyboard 100 shown in Fig. 1. Fig. 14B is a structural diagram of another embodiment of the first fixing base 32 and the second fixing base 33 shown in Fig. 14A at another angle.

[0196] As shown in FIG. 14A and FIG. 14B , the keyboard 100 further includes a plurality of first fixing seats 32 and a plurality of second fixing seats 33 .

[0197] Exemplarily, the first fixing seat 32 includes a first side surface 321 and a second side surface 322 disposed opposite to each other, and a first top surface 323 and a first bottom surface 324 disposed opposite to each other. The first side surface 321 and the second side surface 322 of the first fixing seat 32 are respectively connected between the first top surface 323 and the first bottom surface 324 of the first fixing seat 32.

[0198] As shown in Figures 14A and 14B, the first fixing seat 32 may be provided with a first rotation axis slot 325 and a second rotation axis slot 326 spaced apart from each other. For example, the first rotation axis slot 325 and the second rotation axis slot 326 may extend through the first top surface 323 and the first side surface 321 of the first fixing seat 32. In other embodiments, the first rotation axis slot 325 and the second rotation axis slot 326 may also extend through the second side surface 322 of the first fixing seat 32.

[0199] As shown in Figures 14A and 14B, the first fixing seat 32 is provided with a first stop groove 327. The first stop groove 327 can be located between the first rotation shaft groove 325 and the second rotation shaft groove 326. For example, the first stop groove 327 can pass through the first top surface 323 and the first side surface 321 of the first fixing seat 32.

[0200] It is understood that the second fixing base 33 and the first fixing base 32 of this embodiment can have the same or similar structures, symmetrical or partially symmetrical structures, or different structures. In this embodiment, the second fixing base 33 and the first fixing base 32 have the same structure. The basic design of the component structure of the second fixing base 33, the design of the connection relationship between the components, and the design of other connection relationships between components and assemblies can all refer to the relevant solutions of the first fixing base 32. For example, the second fixing base 33 is provided with a third rotating shaft groove 335, a fourth rotating shaft groove 336, and a second stop groove 337. The second stop groove 337 is located between the third rotating shaft groove 335 and the fourth rotating shaft groove 336. At the same time, the second fixing base 33 and the first fixing base 32 can have slight differences in the detailed structure or position arrangement of the components. The details will not be repeated here.

[0201] 14A and 14B , the first fixing bases 32 and the second fixing bases 33 are disposed on both sides of the triggering ends 21 in a one-to-one correspondence. In other words, one first fixing base 32 and one second fixing base 33 are disposed on both sides of one triggering end 21 .

[0202] For example, the first fixing seat 32 and the second fixing seat 33 are fixed to the reinforcing plate 4. The plurality of first fixing seats 32 and the plurality of second fixing seats 33 are arranged one-to-one on both sides of the plurality of avoidance holes 41. In this case, the first fixing seat 32 and the second fixing seat 33 can be fixed to the circuit board 2 via the reinforcing plate 4.

[0203] For example, the first fixing seat 32 and the second fixing seat 33 can be fixed to the reinforcing plate 4 by snapping, welding or bonding. In other embodiments, the first fixing seat 32 and the second fixing seat 33 can also form an integral structure with the reinforcing plate 4.

[0204] In other embodiments, the first fixing seat 32 and the second fixing seat 33 may also be directly fixed on the circuit board 2, or form an integral structure with the circuit board 2. This application does not limit this in detail.

[0205] The above description specifically describes the configuration of the button 3 in the unpressed state and the triggered state, as well as the arrangement of the multiple buttons 3, in conjunction with the relevant drawings. The following description specifically describes the structure of the button 3 in conjunction with the relevant drawings.

[0206] FIG. 15 is a partially exploded view of the first button 3 a shown in FIG. 2 in one embodiment.

[0207] As shown in Figure 15, the first button 3a includes a first keycap 31a, a first connecting member 34a, a second connecting member 35a, and a first elastic member 36a. The first elastic member 36a may be a spring, a spring, or other elastic structural member. There may be two first elastic members 36a. It is understood that the present application does not specifically limit the number, size, and shape of the first elastic members 36a.

[0208] FIG16 is a schematic structural diagram of the first connecting member 34a and the second connecting member 35a shown in FIG15 at another angle.

[0209] As shown in FIG. 16 , the first connecting member 34 a includes a first rotating end 341 a , a first connecting section 342 a , and a first movable end 343 a , which are sequentially connected.

[0210] Illustratively, the first rotating end 341 a of the first connecting member 34 a includes a first gear portion 344 a , a first rotating portion 345 a , a second rotating portion 346 a , and a first stopping portion 347 a .

[0211] Illustratively, the first gear portion 344a of the first connecting member 34a includes a first end surface 3441a and a second end surface 3442a disposed in opposite directions.

[0212] For example, the first rotating portion 345a and the second rotating portion 346a of the first connecting member 34a can be block-shaped structures. The first rotating portion 345a of the first connecting member 34a is protruded from the first end surface 3441a of the first gear portion 344a. The second rotating portion 346a of the first connecting member 34a is protruded from the second end surface 3442a of the first gear portion 344a.

[0213] For example, the first stop portion 347a of the first connector 34a can be a block-shaped structure. The first stop portion 347a of the first connector 34a is protruding from the first end surface 3441a of the first gear portion 344a and is spaced apart from the first rotating portion 345a of the first connector 34a. In one embodiment, the first stop portion 347a of the first connector 34a is located on a side of the first rotating portion 345a of the first connector 34a that is away from the first movable end 343a of the first connector 34a.

[0214] As shown in FIG16 , the first connecting member 34a is exemplarily provided with a first avoidance hole 3421a. The first avoidance hole 3421a may extend from the first rotation end 341a of the first connecting member 34a to the first connecting section 342a of the first connecting member 34a. In other embodiments, the first avoidance hole 3421a may be provided only at the first rotation end 341a of the first connecting member 34a.

[0215] Exemplarily, the first avoidance hole 3421a divides the first gear portion 344a of the first rotating end 341a of the first connecting member 34a into a first sub-gear portion 3443a and a second sub-gear portion 3444a spaced apart from each other. The first rotating portion 345a protrudes from a surface of the first sub-gear portion 3443a that is distal to the second sub-gear portion 3444a. The second rotating portion 346a protrudes from a surface of the second sub-gear portion 3444a that is distal to the first sub-gear portion 3443a.

[0216] For example, the first sub-gear portion 3443a of the first connecting member 34a includes a first tooth 3445a and a second tooth 3446a. The second tooth 3446a is located on a side of the first tooth 3445a close to the second sub-gear portion 3444a. There is a height difference between the second tooth 3446a and the first tooth 3445a.

[0217] For example, the structure of the second sub-gear portion 3444a of the first connecting member 34a may refer to the structure of the first sub-gear portion 3443a of the first connecting member 34a, and details thereof will not be repeated here.

[0218] As shown in Figure 16, the first connecting section 342a of the first connecting member 34a includes a first connecting shaft 3422a. The number of first connecting shafts 3422a can be two. The number of first connecting shafts 3422a can be the same as the number of first elastic members 36a. In other embodiments, the number, size, and shape of the first connecting shafts 3422a are not specifically limited in this application.

[0219] For example, the first connecting section 342a of the first connecting member 34a is provided with a first mounting hole 3423a. The first mounting hole 3423a is spaced apart from the first avoidance hole 3421a. The portion between the first mounting hole 3423a and the first avoidance hole 3421a can be used to form the first connecting shaft 3422a.

[0220] As shown in FIG. 16 , the first movable end 343 a of the first connecting member 34 a includes a first main body portion 348 a , a first movable portion 3491 a , and a second movable portion 3492 a .

[0221] For example, the first main body portion 348a of the first movable end 343a may be plate-shaped and include a first side surface 3481a and a second side surface 3482a disposed opposite to each other.

[0222] For example, the first movable portion 3491a and the second movable portion 3492a may be block-shaped structures. The first movable portion 3491a is protruded from the first side surface 3481a of the first main body portion 348a. The second movable portion 3492a is protruded from the second side surface 3482a of the first main body portion 348a.

[0223] As shown in FIG. 16 , the second connecting member 35 a includes a second rotating end 351 a , a second connecting section 352 a , and a second movable end 353 a , which are sequentially connected.

[0224] Illustratively, the second rotating end 351a of the second connecting member 35a includes a second gear portion 354a, a third rotating portion 355a, a fourth rotating portion 356a, and a second stop portion 357a. In one embodiment, the pitch circle diameter of the second gear portion 354a of the second connecting member 35a is the same as the pitch circle diameter of the first gear portion 344a of the first connecting member 34a.

[0225] Illustratively, the second gear portion 354a of the second connecting member 35a includes a first end surface 3541a and a second end surface 3542a disposed in opposite directions.

[0226] For example, the third rotating portion 355a and the fourth rotating portion 356a of the second connecting member 35a can be block-shaped structures. The third rotating portion 355a of the second connecting member 35a is protruded from the first end surface 3541a of the second gear portion 354a. The fourth rotating portion 356a of the second connecting member 35a is protruded from the second end surface 3542a of the second gear portion 354a. In other embodiments, the third rotating portion 355a and the fourth rotating portion 356a of the second connecting member 35a can also be through-hole structures.

[0227] Exemplarily, the second stop portion 357a of the second connector 35a can be a block-shaped structure. The second stop portion 357a of the second connector 35a is protruding from the second end surface 3542a of the second gear portion 354a and is spaced apart from the fourth rotating portion 356a of the second connector 35a. In one embodiment, the second stop portion 357a of the second connector 35a is located on a side of the fourth rotating portion 356a of the second connector 35a that is away from the second movable end 353a of the second connector 35a.

[0228] As shown in FIG16 , the second connecting member 35a is exemplarily provided with a second avoidance hole 3521a. The second avoidance hole 3521a can extend from the second rotation end 351a of the second connecting member 35a to the second connecting section 352a of the second connecting member 35a. In other embodiments, the second avoidance hole 3521a can also be provided only at the second rotation end 351a of the second connecting member 35a.

[0229] Exemplarily, the second avoidance hole 3521a divides the second gear portion 354a of the second rotating end 351a of the second connecting member 35a into a first sub-gear portion 3543a and a second sub-gear portion 3544a spaced apart from each other. The third rotating portion 355a protrudes from a surface of the first sub-gear portion 3543a that is distal to the second sub-gear portion 3544a. The fourth rotating portion 356a protrudes from a surface of the second sub-gear portion 3544a that is distal to the first sub-gear portion 3543a.

[0230] Exemplarily, the first sub-gear portion 3543a of the second connecting member 35a includes a first tooth 3545a and a second tooth 3546a. The second tooth 3546a is located on a side of the first tooth 3545a closer to the second sub-gear portion 3544a. The second tooth 3546a is at a height difference from the first tooth 3545a. In other words, the first teeth 3545a and the second teeth 3546a of the second connecting member 35a are staggered in the thickness direction of the second connecting member 35a.

[0231] For example, the structure of the second sub-gear portion 3544a of the second connecting member 35a may refer to the structure of the first sub-gear portion 3543a of the second connecting member 35a, and will not be further described herein.

[0232] As shown in Figure 16, the second connecting section 352a of the second connecting member 35a includes a second connecting shaft 3522a. The number of second connecting shafts 3522a can be two. The number of second connecting shafts 3522a can be the same as the number of first elastic members 36a. In other embodiments, the number, size, and shape of the second connecting shafts 3522a are not specifically limited in this application.

[0233] For example, the second connecting section 352a of the second connecting member 35a is provided with a second mounting hole 3523a. The second mounting hole 3523a is spaced apart from the second avoidance hole 3521a. The portion between the second mounting hole 3523a and the second avoidance hole 3521a can be used to form the second connecting shaft 3522a.

[0234] As shown in FIG. 16 , the second movable end 353 a of the second connecting member 35 a includes a second main body portion 358 a , a third movable portion 3591 a , and a fourth movable portion 3592 a .

[0235] For example, the second body portion 358a of the third movable end 353a may be plate-shaped and include a first side surface 3581a and a second side surface 3582a disposed opposite to each other.

[0236] For example, the third movable portion 3591a and the fourth movable portion 3592a may be block-shaped structures. The third movable portion 3591a is protruded from the first side surface 3581a of the second main body portion 358a. The fourth movable portion 3592a is protruded from the second side surface 3582a of the second main body portion 358a.

[0237] It is understood that the second connector 35a and the first connector 34a of this embodiment may have the same or similar structures, symmetrical or partially symmetrical structures, or different structures. In this embodiment, the second connector 35a and the first connector 34a have the same structure. The basic design of the component structure of the second connector 35a, the connection relationship design between the components, and the design of other connection relationships between components and assemblies can all refer to the relevant solutions of the first connector 34a. At the same time, the second connector 35a and the first connector 34a may have slight differences in the detailed structure or position arrangement of the components. The details will not be repeated here.

[0238] Fig. 17 is a schematic diagram of a portion of the structure of the keyboard 100 shown in Fig. 1 in one embodiment. Fig. 18 is a schematic diagram of a portion of the keyboard 100 shown in Fig. 17 taken along line BB in one embodiment.

[0239] As shown in Figures 17 and 18, the first connecting member 34a can be movably connected to the first fixing seat 32 and the second fixing seat 33. For example, the first rotating end 341a of the first connecting member 34a can be rotatably connected to the first fixing seat 32 and the second fixing seat 33. As shown in Figure 14A, since the first fixing seat 32 and the second fixing seat 33 are fixed to the circuit board 2, the first connecting member 34a can be rotatably connected to the circuit board 2 via the first fixing seat 32 and the second fixing seat 33 (see Figure 14A). In other embodiments, when the first button 3a does not include the first fixing seat 32 and the second fixing seat 33, or when the first fixing seat 32 and the second fixing seat 33 are integrally formed with the circuit board 2, the first connecting member 34a is directly rotatably connected to the circuit board 2 (see Figure 14A).

[0240] For example, the first rotating portion 345a of the first rotating end 341a of the first connecting member 34a can be located within the first rotating shaft groove 325 of the first fixing seat 32. The first rotating portion 345a of the first rotating end 341a of the first connecting member 34a can rotate within the first rotating shaft groove 325 of the first fixing seat 32. In other embodiments, the structure of the first rotating portion 345a of the first connecting member 34a and the structure of the first rotating shaft groove 325 of the first fixing seat 32 can be reversed, that is, the first rotating portion 345a of the first connecting member 34a can adopt a rotating shaft groove structure or a rotating shaft hole structure. The first fixing seat 32 can be provided with a rotating shaft protrusion structure.

[0241] For example, the second rotating portion 346a of the first rotating end 341a of the first connecting member 34a can be located within the third rotating shaft groove 335 of the second fixing seat 33. The second rotating portion 346a of the first rotating end 341a of the first connecting member 34a can rotate within the third rotating shaft groove 335 of the second fixing seat 33. In other embodiments, the structure of the second rotating portion 346a of the first connecting member 34a and the structure of the third rotating shaft groove 335 of the second fixing seat 33 can be reversed, that is, the second rotating portion 346a of the first connecting member 34a can adopt a rotating shaft groove structure or a rotating shaft hole structure. The second fixing seat 33 can be provided with a rotating shaft protrusion structure.

[0242] As shown in Figures 17 and 18, the second connecting member 35a can be movably connected to the first fixing base 32 and the second fixing base 33. For example, the second rotating end 351a of the second connecting member 35a can be rotatably connected to the first fixing base 32 and the second fixing base 33. It is understood that the second connecting member 35a can be rotatably connected to the circuit board 2 via the first fixing base 32 and the second fixing base 33 (see Figure 14A). In other embodiments, when the first button 3a does not include the first fixing base 32 and the second fixing base 33, the second connecting member 35a can also be directly connected to the circuit board 2 (see Figure 14A).

[0243] For example, the third rotating portion 355a of the second rotating end 351a of the second connecting member 35a can be located in the second rotating shaft groove 326 of the first fixing seat 32. The third rotating portion 355a of the second rotating end 351a of the second connecting member 35a can rotate in the second rotating shaft groove 326 of the first fixing seat 32.

[0244] For example, the fourth rotating portion 356a of the second rotating end 351a of the second connecting member 35a can be located in the fourth rotating shaft groove 336 of the second fixing seat 33. The fourth rotating portion 356a of the second rotating end 351a of the second connecting member 35a can rotate in the fourth rotating shaft groove 336 of the second fixing seat 33.

[0245] FIG19 is a partial cross-sectional schematic diagram of an embodiment of a portion of the keyboard 100 shown in FIG17 at line CC.

[0246] 19 , in combination with FIG. 17 and FIG. 18 , the first gear portion 344a of the first rotating end 341a of the first connecting member 34a may be engaged with the second gear portion 354a of the second rotating end 351a of the second connecting member 35a.

[0247] In one embodiment, the first sub-gear portion 3443a of the first connecting member 34a can mesh with the first sub-gear portion 3543a of the second connecting member 35a. For example, the first tooth 3445a of the first sub-gear portion 3443a of the first connecting member 34a meshes with the first tooth 3545a of the first sub-gear portion 3543a of the second connecting member 35a. The second tooth 3446a (see FIG. 16 ) of the first sub-gear portion 3443a of the first connecting member 34a meshes with the second tooth 3546a of the first sub-gear portion 3543a of the second connecting member 35a. Furthermore, the line connecting the first tooth 3445a and the second tooth 3446a (see FIG. 16 ) of the first connecting member 34a and the line connecting the first tooth 3545a and the second tooth 3546a of the first sub-gear portion 3543a of the second connecting member 35a are arranged to intersect. In other words, the first teeth 3445a and second teeth 3446a (see FIG. 16 ) of the first sub-gear portion 3443a of the first connecting member 34a can interlock and mesh with the first teeth 3545a and second teeth 3546a of the first sub-gear portion 3543a of the second connecting member 35a. Thus, the first sub-gear portion 3443a of the first connecting member 34a and the first sub-gear portion 3543a of the second connecting member 35a can be mutually restrained in the X-axis direction, thereby preventing the first sub-gear portion 3443a of the first connecting member 34a and the first sub-gear portion 3543a of the second connecting member 35a from disengaging in the X-axis direction.

[0248] Referring to FIG. 19 , and in conjunction with FIG. 17 and FIG. 18 , the second sub-gear portion 3444a of the first connecting member 34a also meshes with the second sub-gear portion 3544a of the second connecting member 35a. It will be appreciated that the meshing method of the second sub-gear portion 3444a of the first connecting member 34a and the second sub-gear portion 3544a of the second connecting member 35a can be similar to the meshing method of the first sub-gear portion 3443a of the first connecting member 34a and the first sub-gear portion 3543a of the second connecting member 35a. Details will not be repeated here.

[0249] It is understood that the first gear portion 344a of the first rotating end 341a of the first connecting member 34a and the second gear portion 354a of the second rotating end 351a of the second connecting member 35a are engaged, so that the rotational movements of the first connecting member 34a and the second connecting member 35a can be synchronized, that is, they can move toward or away from each other synchronously. In addition, because the diameter of the pitch circle of the second gear portion 354a of the second connecting member 35a is the same as the diameter of the pitch circle of the first gear portion 344a of the first connecting member 34a, that is, the ratio of the diameter of the pitch circle of the second gear portion 354a of the second connecting member 35a to the diameter of the pitch circle of the first gear portion 344a of the first connecting member 34a is 1, the rotation angles of the first connecting member 34a and the second connecting member 35a can be the same.

[0250] It is understood that although this embodiment describes a structure of the first gear portion 344a of the first rotating end 341a of the first connecting member 34a and the second gear portion 354a of the second rotating end 351a of the second connecting member 35a, in other embodiments, the first gear portion 344a of the first rotating end 341a of the first connecting member 34a and the second gear portion 354a of the second rotating end 351a of the second connecting member 35a may also adopt other structures. For example, the shape and size of the first gear portion 344a of the first rotating end 341a of the first connecting member 34a and the second gear portion 354a of the second rotating end 351a of the second connecting member 35a can be designed according to the specific form, size, etc. of the product.

[0251] As shown in Figures 17 to 19, when the first button 3a is not pressed, the angle between the first connecting member 34a and the second connecting member 35a is a first angle. The first angle can be in the range of 120° to 160°. For example, the first angle can be 120°, 125°, 145°, 150°, or 160°. At this time, the first connecting member 34a and the second connecting member 35a are roughly in a "scissor" shape.

[0252] Furthermore, when the first button 3a is not pressed, the first avoidance hole 3421a of the first connector 34a communicates with the second avoidance hole 3521a of the second connector 35a. The space enclosed by the first avoidance hole 3421a and the second avoidance hole 3521a can be used to provide avoidance space for other components of the first button 3a or other components of the keyboard 100, thereby preventing interference between the first connector 34a and the second connector 35a.

[0253] As shown in Figures 17 and 18 in conjunction with Figure 14B , when the first button 3a is in the unpressed state, at least a portion of the first stop portion 347a of the first rotating end 341a of the first connecting member 34a can be located within the first stop groove 327 of the first fixing seat 32 and abut against the bottom wall of the first stop groove 327. The bottom wall of the first stop groove 327 can be used to limit the first connecting member 34a from further rotation relative to the first fixing seat 32 when the first button 3a is in the unpressed state. Furthermore, at least a portion of the second stop portion 357a of the second rotating end 351a of the second connecting member 35a can be located within the second stop groove 337 of the second fixing seat 33 and abut against the bottom wall of the second stop groove 337. The bottom wall of the second stop groove 337 can be used to limit the second connecting member 35a from further rotation relative to the second fixing seat 33 when the first button 3a is in the unpressed state.

[0254] Fig. 20 is a schematic structural diagram of a portion of the keyboard 100 shown in Fig. 17 in a triggered state. Fig. 21 is a cross-sectional view of a portion of the keyboard 100 shown in Fig. 20 taken along line DD of an embodiment.

[0255] As shown in Figures 20 and 21, when the first button 3a is in the triggered state, the angle between the first connecting member 34a and the second connecting member 35a is a second angle. The second angle is greater than the first angle. For example, the second angle can be in the range of 160° to 180°. For example, the second angle can be 160°, 170°, or 180°. In this case, when the second angle is 180°, the first connecting member 34a and the second connecting member 35a can form a "straight" shape.

[0256] In addition, when the first button 3 a is in the triggered state, the first stopping portion 347 a can be separately provided from the bottom wall of the first stopping groove 327 , and the second stopping portion 357 a can be separately provided from the bottom wall of the second stopping groove 337 .

[0257] FIG. 22 is a second schematic diagram of a partial structure of the keyboard 100 shown in FIG. 1 in one embodiment.

[0258] As shown in Figure 22, the first elastic member 36a connects the first connecting member 34a and the second connecting member 35a. The first elastic member 36a is in a stretched state. At this time, the first elastic member 36a can be used to apply tension to the first connecting member 34a and the second connecting member 35a.

[0259] For example, the first elastic member 36a may be a spring. The first end 361a of the first elastic member 36a (see FIG. 15 ) may pass through the first mounting hole 3423a of the first connecting member 34a and be hooked onto the first connecting shaft 3422a of the first connecting member 34a (see FIG. 16 ). The second end 362a of the first elastic member 36a (see FIG. 15 ) may pass through the second mounting hole 3523a of the second connecting member 35a and be hooked onto the second connecting shaft 3522a of the second connecting member 35a (see FIG. 16 ). In this embodiment, the connection method between the first elastic member 36a and the first and second connecting members 34a, 35a is relatively simple. In other embodiments, when the first elastic member 36a employs other structural forms, the connection method between the first elastic member 36a and the first and second connecting members 34a, 35a is not specifically limited. In other embodiments, the first button 3a may also not employ the first elastic member 36a, but instead utilize other drive mechanisms to drive the movement of the first and second connecting members 34a, 35a.

[0260] As shown in FIG. 22 , when the first button 3 a is in an unpressed state, at least a portion of the first elastic member 36 a may be located in a space surrounded by the first avoidance hole 3421 a of the first connecting member 34 a and the second avoidance hole 3521 a of the second connecting member 35 a .

[0261] FIG. 23 is a schematic structural diagram of the first keycap 31 a shown in FIG. 15 at another angle.

[0262] As shown in Figure 23, the first keycap 31a includes a first pressing plate 311a and a first frame 312a. The first pressing plate 311a includes a top surface 313a and a bottom surface 314a, which are disposed in opposite directions. The top surface 313a of the first pressing plate 311a serves as the top surface 30a of the first key 3a (see Figures 4 to 11). The first frame 312a is fixed to the bottom surface 314a of the first pressing plate 311a. The first pressing plate 311a and the first frame 312a enclose a first receiving slot 315a.

[0263] Exemplarily, the first keycap 31a further includes a first guide rail block 3161a, a second guide rail block 3162a, a third guide rail block 3163a, and a fourth guide rail block 3164a. The first guide rail block 3161a, the second guide rail block 3162a, the third guide rail block 3163a, and the fourth guide rail block 3164a are all protruded from the bottom surface 314a of the first pressing plate 311a and are all located in the first receiving groove 315a.

[0264] In addition, the first guide rail block 3161a, the second guide rail block 3162a, the third guide rail block 3163a, and the fourth guide rail block 3164a are all provided with guide grooves 3165a. The guide grooves 3165a of the first guide rail block 3161a are arranged opposite to the guide grooves 3165a of the second guide rail block 3162a. The guide grooves 3165a of the third guide rail block 3163a are arranged opposite to the guide grooves 3165a of the fourth guide rail block 3164a.

[0265] For example, the guide grooves 3165a of the first guide rail block 3161a, the second guide rail block 3162a, the third guide rail block 3163a, and the fourth guide rail block 3164a may all be in a strip shape.

[0266] As shown in Figure 23, the first keycap 31a also includes a first stopper 3171a and a second stopper 3172a. The first stopper 3171a and the second stopper 3172a can be in the shape of a cuboid, a cylinder, or other shapes. This embodiment is described using the first stopper 3171a and the second stopper 3172a in the shape of a cuboid as an example. The first stopper 3171a and the second stopper 3172a are both protruding from the bottom surface 314a of the first pressing plate 311a and are both located within the first receiving groove 315a. The first stopper 3171a is located on the same side of the first guide rail block 3161a and the second guide rail block 3162a, and the first stopper 3171a is directly opposite the space between the first guide rail block 3161a and the second guide rail block 3162a. The second stopper 3172a is located on the same side of the third guide rail block 3163a and the fourth guide rail block 3164a, and the second stopper 3172a is aligned with the space between the third guide rail block 3163a and the fourth guide rail block 3164a.

[0267] As shown in Figure 23, the first keycap 31a is also provided with an avoidance groove 318a. The opening of the avoidance groove 318a is located at the bottom surface 314a of the first pressing plate 311a. It can be understood that the avoidance groove 318a can be used to provide avoidance space for other components of the first key 3a or other components of the keyboard 100, thereby avoiding interference between other components of the first key 3a, other components of the keyboard 100 and the first keycap 31a, that is, preventing other components of the first key 3a or other components of the keyboard 100 from colliding with the first keycap 31a, resulting in dislocation, wear and even breakage, thereby extending the service life of the first key 3a. In addition, Figure 23 only schematically shows some avoidance grooves 318a. Regarding the number, shape, size and position of the avoidance grooves 318a, this application does not make specific restrictions. For example, it can be designed according to the specific form and size of the product.

[0268] Fig. 24 is a partial structural diagram of an embodiment of the first key 3a shown in Fig. 2. Fig. 25 is a partial cross-sectional diagram of an embodiment of a portion of the first key 3a shown in Fig. 24 taken along line EE.

[0269] As shown in Figures 24 and 25, the first movable end 343a of the first connecting member 34a is movably connected to the first keycap 31a. For example, the first movable end 343a of the first connecting member 34a is slidably connected to the first keycap 31a and can rotate relative to each other.

[0270] Exemplarily, the first body portion 348a of the first movable end 343a of the first connecting member 34a is positioned between the first guide rail block 3161a and the second guide rail block 3162a of the first keycap 31a. The first movable portion 3491a of the first movable end 343a of the first connecting member 34a is positioned within the guide groove 3165a of the first guide rail block 3161a of the first keycap 31a and can slide and rotate within the guide groove 3165a of the first guide rail block 3161a. The second movable portion 3492a of the first movable end 343a of the first connecting member 34a is positioned within the guide groove 3165a of the second guide rail block 3162a of the first keycap 31a and can slide and rotate within the guide groove 3165a of the second guide rail block 3162a.

[0271] As shown in Figure 25, the second movable end 353a of the second connecting member 35a is movably connected to the first keycap 31a. Exemplarily, the second movable end 353a of the second connecting member 35a is slidably connected to the first keycap 31a and can rotate relative to each other.

[0272] Exemplarily, the second body portion 358a of the second movable end 353a of the second connecting member 35a is positioned between the third guide rail block 3163a and the fourth guide rail block 3164a of the first keycap 31a. The third movable portion 3591a of the second movable end 353a of the second connecting member 35a is positioned within the guide groove 3165a of the third guide rail block 3163a of the first keycap 31a and can slide and rotate within the guide groove 3165a of the third guide rail block 3163a. ​​The fourth movable portion 3592 of the second movable end 353a of the second connecting member 35a is positioned within the guide groove 3165a of the fourth guide rail block 3164a of the first keycap 31a and can slide and rotate within the guide groove 3165a of the fourth guide rail block 3164a.

[0273] As shown in Figure 25, when the first button 3a is in an unpressed state, the first movable portion 3491a of the first connecting member 34a abuts against the wall surface of the guide groove 3165a of the first guide rail block 3161a, the second movable portion 3492a of the first connecting member 34a abuts against the wall surface of the guide groove 3165a of the second guide rail block 3162a, the third movable portion 3591a of the second connecting member 35a abuts against the wall surface of the guide groove 3165a of the third guide rail block 3163a, and the fourth movable portion 3592 of the second connecting member 35a abuts against the wall surface of the guide groove 3165a of the fourth guide rail block 3164a. It is understood that the interaction between the walls of the guide groove 3165a of the first guide rail block 3161a and the walls of the guide groove 3165a of the second guide rail block 3162a can restrict the first connecting member 34a from continuing to slide and rotate relative to the first keycap 31a when the first key 3a is not pressed. In addition, the interaction between the walls of the guide groove 3165a of the third guide rail block 3163a and the walls of the guide groove 3165a of the fourth guide rail block 3164a can restrict the second connecting member 35a from continuing to slide and rotate relative to the first keycap 31a when the first key 3a is not pressed.

[0274] Figure 26 is a schematic structural diagram of a portion of the first button 3a shown in Figure 24 in a triggered state. Figure 27 is a cross-sectional view of a portion of the first button 3a shown in Figure 26 at line FF in an embodiment.

[0275] As shown in Figures 26 and 27, when the first button 3a is in the triggered state, the first movable portion 3491a of the first connecting member 34a and the wall surface of the guide groove 3165a of the first guide rail block 3161a are separately arranged in the positive direction of the Y-axis, the second movable portion 3492a of the first connecting member 34a and the wall surface of the guide groove 3165a (please refer to Figure 25) of the second guide rail block 3162a are separately arranged in the positive direction of the Y-axis, the third movable portion 3591a of the second connecting member 35a and the wall surface of the guide groove 3165a of the third guide rail block 3163a are separately arranged in the negative direction of the Y-axis, and the fourth movable portion 3592 of the second connecting member 35a and the wall surface of the guide groove 3165a of the fourth guide rail block 3164a are separately arranged in the negative direction of the Y-axis.

[0276] As shown in Figures 26 and 27, when the first button 3a is in the triggered state, the first body portion 348a of the first movable end 343a of the first connecting member 34a abuts against the first stopper 3171a, and the second body portion 358a of the second movable end 353a of the second connecting member 35a abuts against the second stopper 3172a. It will be appreciated that the first stopper 3171a can be used to stop the first connecting member 34a when the first button 3a is in the triggered state, preventing the first movable end 343a of the first connecting member 34a from moving out of the guide groove 3165a of the first guide rail block 3161a and the second guide rail block 3162a. The second stopper 3172a can be used to stop the second connecting member 35a when the first button 3a is in the triggered state, preventing the second movable end 353a of the second connecting member 35a from moving out of the guide groove 3165a of the third guide rail block 3163a and the fourth guide rail block 3164a.

[0277] FIG28 is a partial cross-sectional view of a portion of the keyboard 100 shown in FIG1 at line GG according to an embodiment.

[0278] As shown in Figure 28, when the first key 3a is not pressed, the first connecting member 34a and the second connecting member 35a support the first keycap 31a. In the Z-axis direction, the distance between the first keycap 31a and the trigger end 21 of the circuit board 2 is a first distance D1.

[0279] For example, when the first button 3a is not pressed, the first elastic member 36a (see FIG. 22 ) can be in a stretched state. This allows the first elastic member 36a to apply a force along the positive Z-axis to the first keycap 31a via the first connector 34a and the second connector 35a. In this case, if a user accidentally touches the first keycap 31a, the first keycap 31a will not immediately move along the negative Z-axis, and the first keycap 31a will not press against the trigger terminal 21 of the circuit board 2 to generate an electrical signal.

[0280] FIG29 is a partial cross-sectional view of an embodiment of a portion of the keyboard 100 shown in FIG28 in a triggered state.

[0281] As shown in FIG29 , when the first key 3a is in the triggered state, the distance between the first keycap 31a and the trigger end 21 of the circuit board 2 in the Z-axis direction is a second distance D2. The second distance D2 is smaller than the first distance D1 (see FIG28 ). At this time, the distance between the first keycap 31a and the trigger end of the circuit board is relatively short.

[0282] As shown in Figures 28 and 29, when the first button 3a switches from the unpressed state to the triggered state, the first keycap 31a is pressed, causing it to move along the negative direction of the Z-axis. The first keycap 31a squeezes the first connecting member 34a and the second connecting member 35a, allowing the first rotating end 341a of the first connecting member 34a and the second rotating end 351a of the second connecting member 35a to rotate relative to the first fixed seat 32 and the second fixed seat 33. Furthermore, the first movable end 343a of the first connecting member 34a can slide and rotate relative to the first keycap 31a, and the second movable end 353a of the second connecting member 35a can slide and rotate relative to the first keycap 31a. This causes the first movable end 343a of the first connecting member 34a and the second movable end 353a of the second connecting member 35a to move away from each other, and the first connecting member 34a and the second connecting member 35a to open, thereby increasing the angle between the first connecting member 34a and the second connecting member 35a. Furthermore, the first elastic member 36a is stretched and in a tensioned state. It will be appreciated that when the first keycap 31a moves in the negative direction of the Z-axis, the distance between the first keycap 31a and the trigger end 21 of the circuit board 2 decreases. In this way, the first keycap 31a can indirectly or directly compress the trigger end 21 of the circuit board 2, causing the circuit board 2 to generate an electrical signal.

[0283] It is understood that when the first button 3a switches from the unpressed state to the triggered state, the first elastic member 36a can apply a force along the positive direction of the Z-axis to the first keycap 31a through the first connecting member 34a and the second connecting member 35a. In this case, when the first keycap 31a is pressed and moves along the negative direction of the Z-axis, the force applied by the first elastic member 36a on the first keycap 31a must first be overcome, thereby improving the user's feel when pressing the first keycap 31a.

[0284] In one embodiment, the keyboard 100 includes a trigger member 5, which is an elastic member. The following description uses the trigger member 5 as an example, wherein the trigger member 5 is fixed to the trigger end 21 of the circuit board 2. Thus, when the first keycap 31a moves into contact with the trigger member 5, the first keycap 31a can compress the trigger member 5. The trigger member 5 can deform and enter a compressed state. The trigger member 5 can use its own elastic force to compress the trigger end 21 of the circuit board 2, causing the circuit board 2 to generate an electrical signal.

[0285] In one embodiment, the keyboard 100 does not include the trigger member 5. At this time, as the distance between the first keycap 31a and the trigger end 21 of the circuit board 2 decreases, the first keycap 31a can directly contact the trigger end 21 of the circuit board 2 and press the trigger end 21 of the circuit board 2, causing the circuit board 2 to generate an electrical signal.

[0286] It can be understood that because the pitch circle diameter of the second gear portion 354a of the second connecting member 35a is the same as the pitch circle diameter of the first gear portion 344a of the first connecting member 34a, when the second gear portion 354a of the second connecting member 35a meshes with the first gear portion 344a of the first connecting member 34a, the rotation angle of the second connecting member 35a is the same as the rotation angle of the first connecting member 34a. At this time, the movement speed of the portion of the first keycap 31a connected to the first connecting member 34a is the same as the movement speed of the portion of the first keycap 31a connected to the second connecting member 35a. When the first key 3a is in the triggered state, the first keycap 31a is arranged substantially parallel to the circuit board 2. That is, the angle A1 between the first central axis L1 of the first key 3a and the central axis L0 of the circuit board 2 is relatively small. For example, A1 can satisfy the following: 0°≤A1<3°.

[0287] As shown in Figures 28 and 29, when the first key 3a switches from the triggered state to the unpressed state, a force is applied to the first connecting member 34a and the second connecting member 35a, causing the first rotating end 341a of the first connecting member 34a and the second rotating end 351a of the second connecting member 35a to rotate relative to the first fixed base 32 and the second fixed base 33. The first movable end 343a of the first connecting member 34a and the second movable end 353a of the second connecting member 35a can both slide relative to the first keycap 31a and rotate relative to each other. In this way, the first movable end 343a of the first connecting member 34a and the second movable end 353a of the second connecting member 35a approach each other, and the first connecting member 34a and the second connecting member 35a move closer to each other, that is, the angle between the first connecting member 34a and the second connecting member 35a decreases. The first connecting member 34a and the second connecting member 35a can compress the first keycap 31a, allowing the first keycap 31a to move along the positive direction of the Z axis. It is understandable that when the first keycap 31a moves along the positive direction of the Z-axis, the distance between the first keycap 31a and the trigger end 21 of the circuit board 2 increases. In this way, the first keycap 31a no longer directly or indirectly compresses the trigger end 21 of the circuit board 2, and the circuit board 2 does not generate an electrical signal.

[0288] It is understandable that when the first button 3a switches from the triggered state to the unpressed state, there are multiple ways to apply force to the first connecting member 34a and the second connecting member 35a. Two embodiments will be described in detail below with reference to the relevant drawings.

[0289] FIG30 is a partially exploded schematic diagram of the keyboard 100 shown in FIG1 in another embodiment.

[0290] As shown in FIG30 , the first elastic member 36a has a first centerline La. The first centerline La passes through the center of the first elastic member 36a and is parallel to the longitudinal extension direction of the first elastic member 36a. It will be appreciated that when the first elastic member 36a is a spring, the first centerline La of the first elastic member 36a may be the central axis of the spring.

[0291] When the first button 3a is in the triggered state, the first center line La of the first elastic member 36a is arranged at an angle to the top surface 22 of the circuit board 2. That is, the first center line La of the first elastic member 36a is not parallel to the top surface 22 of the circuit board 2. The top surface 22 of the circuit board 2 is the surface of the circuit board 2 facing the first button 3a.

[0292] It is understood that because the first centerline La of the first elastic member 36a is not parallel to the top surface 22 of the circuit board 2, the elastic force exerted by the first elastic member 36a on the first connecting member 34a and the second connecting member 35a can generate a force component in the positive direction of the Z-axis. In this case, this force component can cause the first rotating end 341a of the first connecting member 34a to rotate counterclockwise relative to the first fixing seat 32 and the second fixing seat 33, and the second rotating end 351a of the second connecting member 35a to rotate clockwise relative to the first fixing seat 32 and the second fixing seat 33, thereby switching the first button 3a from the triggered state to the unpressed state.

[0293] In other embodiments, when the first button 3a is in the triggered state, the first center line La of the first elastic member 36a may be arranged parallel to the circuit board 2. In this case, other embodiments (such as the embodiments described below) may be adopted to enable the first button 3a to switch from the triggered state to the unpressed state.

[0294] FIG31 is a partial cross-sectional view of another embodiment of the keyboard 100 shown in FIG28 in a triggered state.

[0295] As shown in Figure 31, the center of rotation of the first connecting member 34a relative to the first fixing base 32 is the first rotation center O1. The center of rotation of the first connecting member 34a relative to the first keycap 31a is the second rotation center O2. The distance between the first rotation center O1 and the bottom surface 23 of the circuit board 2 is the first height H1. The distance between the second rotation center O2 and the bottom surface 23 of the circuit board 2 is the second height H2. The bottom surface 23 of the circuit board 2 is the surface of the circuit board 2 facing away from the first keycap 31a.

[0296] When the first button 3a is in the triggered state, the first height H1 is less than the second height H2, that is, H1 and H2 satisfy: H1 < H2. At this time, the elastic force exerted by the first elastic member 36a on the first connecting member 34a can generate a component force in the positive direction of the Z-axis. This component force can cause the first rotating end 341a of the first connecting member 34a to rotate counterclockwise relative to the first fixed seat 32 and the second fixed seat 33. As shown in FIG. 19, since the first gear portion 344a of the first rotating end 341a of the first connecting member 34a meshes with the second gear portion 354a of the second rotating end 351a of the second connecting member 35a, the first rotating end 341a of the first connecting member 34a and the second rotating portion 355a of the second connecting member 35a can rotate synchronously, that is, the second rotating end 351a of the second connecting member 35a can rotate clockwise relative to the first fixed seat 32 and the second fixed seat 33, so that the first button 3a can be switched from the triggered state to the unpressed state.

[0297] Similarly, the distance between the center O3 of the second connecting member 35a rotating relative to the first fixed seat 32 and the bottom surface 23 of the circuit board 2 is the third height H3. The distance between the center O4 of the second connecting member 35a rotating relative to the first keycap 31a and the bottom surface 23 of the circuit board 2 is the fourth height H4. When the first button 3a is in the triggered state, the third height H3 is less than the fourth height H4, that is, H3 and H4 satisfy: H3 < H4. In this way, the elastic force exerted by the first elastic member 36a on the second connecting member 35a can generate a component force in the positive direction of the Z-axis. This component force can cause the first button 3a to be switched from the triggered state to the unpressed state.

[0298] In other embodiments, when the first button 3a is in the triggered state, the second height H2 may also be equal to the first height H1, and the fourth height H4 may also be equal to the third height H3. At this time, other embodiments (such as the embodiments below) can be adopted to make the first button 3a be switched from the triggered state to the unpressed state.

[0299] As shown in FIGS. 28 and 29, the keyboard 100 includes a trigger member 5, and the trigger member 5 is an elastic member. Taking the trigger member 5 being fixed on the trigger end 21 of the circuit board 2 as an example for description. When the first button 3a is in the triggered state, the trigger member 5 is in a compressed state, and the trigger member 5 can use its own elastic force to squeeze the trigger end 21 of the circuit board 2 to cause the circuit board 2 to generate an electrical signal.

[0300] When the first button 3a switches from the triggered state to the unpressed state, since the first keycap 31a is no longer subjected to pressing force, the elastic force exerted by the trigger member 5 on the first keycap 31a causes the first keycap 31a to move in the positive direction of the Z-axis. At this point, the first keycap 31a exerts a force on the first connecting member 34a and the second connecting member 35a, causing the first rotating end 341a of the first connecting member 34a to rotate counterclockwise relative to the first fixing seat 32 and the second fixing seat 33, and the second rotating end 351a of the second connecting member 35a to rotate clockwise relative to the first fixing seat 32 and the second fixing seat 33. In this way, the first button 3a can switch from the triggered state to the unpressed state.

[0301] The structure of the first button 3a is described in detail above with reference to the relevant drawings. An assembly method of the first button 3a is described below with reference to the relevant drawings.

[0302] As shown in FIG. 22 , first, one end of the first elastic member 36a is connected to the first connecting member 34a, and the other end is connected to the second connecting member 35a.

[0303] 19 , secondly, the first gear portion 344a of the first rotating end 341a of the first connecting member 34a is meshed with the second gear portion 354a of the second rotating end 351a of the second connecting member 35a.

[0304] 18 , secondly, the first rotating end 341a of the first connecting member 34a is rotatably connected to the first fixed seat 32 and the second fixed seat 33, and at least a portion of the first stop portion 347a of the first rotating end 341a of the first connecting member 34a is located in the first stop groove 327 of the first fixed seat 32 and is abutted against the bottom wall of the first stop groove 327, and the second rotating end 351a of the second connecting member 35a is rotatably connected to the first fixed seat 32 and the second fixed seat 33, and at least a portion of the second stop portion 357a of the second rotating end 351a of the second connecting member 35a is located in the second stop groove 337 of the second fixed seat 33 and is abutted against the bottom wall of the second stop groove 337.

[0305] 14A and 14B , the first fixing base 32 and the second fixing base 33 are fixed on the circuit board 2 , and are respectively on two sides of the trigger end 21 .

[0306] 23 to 25 , finally, the first movable end 343a of the first connecting member 34a and the second movable end 353a of the second connecting member 35a are both movably connected to the first keycap 31a.

[0307] It is understandable that when the keyboard 100 includes the trigger member 5 , the trigger member 5 can be installed on the first keycap 31 a in advance, or installed on the trigger end 21 , etc.

[0308] The above description specifically describes several implementations of the first button 3a switching from the triggered state to the unpressed state in conjunction with the relevant drawings. The following description specifically describes other structures of the first connecting member 34a and the second connecting member 35a in conjunction with the relevant drawings.

[0309] FIG32 is a schematic structural diagram of the first connecting member 34 a and the second connecting member 35 a shown in FIG15 in another embodiment.

[0310] As shown in Figure 32, the first connecting member 34a is provided with a first avoidance hole 3421a that divides the first gear portion 344a of the first rotating end 341a of the first connecting member 34a into a first sub-gear portion 3443a and a second sub-gear portion 3444a that are spaced apart.

[0311] For example, the first sub-gear portion 3443a of the first connecting member 34a includes a first tooth 3445a, and the second sub-gear portion 3444a of the first connecting member 34a includes a second tooth 3446a and a third tooth 3447a that are spaced apart and arranged opposite to each other.

[0312] As shown in Figure 32, the second connecting member 35a is provided with a second avoidance hole 3521a that divides the second gear portion 354a of the second rotating end 351a of the second connecting member 35a into a first sub-gear portion 3543a and a second sub-gear portion 3544a that are spaced apart.

[0313] For example, the first sub-gear portion 3543a of the second connecting member 35a includes a first tooth 3545a and a second tooth 3546a that are spaced apart and opposite to each other, and the second sub-gear portion 3544a of the second connecting member 35a includes a third tooth 3547a.

[0314] FIG33 is a schematic diagram of the assembly of the first connecting member 34 a and the second connecting member 35 a shown in FIG32 .

[0315] As shown in Figures 32 and 33, the first sub-gear portion 3443a of the first connecting member 34a can mesh with the first sub-gear portion 3543a of the second connecting member 35a. The first tooth 3445a of the first connecting member 34a can be located between the first tooth 3545a and the second tooth 3546a of the second connecting member 35a.

[0316] As shown in Figures 32 and 33, the second sub-gear portion 3444a of the first connecting member 34a can be engaged with the second sub-gear portion 3544a of the second connecting member 35a. The third tooth 3547a of the second connecting member 35a can be located between the second tooth 3446a and the third tooth 3447a of the first connecting member 34a.

[0317] It can be understood that by setting the first sub-gear portion 3443a of the first connecting member 34a to mesh with the first sub-gear portion 3543a of the second connecting member 35a, and the second sub-gear portion 3444a of the first connecting member 34a to mesh with the second sub-gear portion 3544a of the second connecting member 35a, the first rotating end 341a of the first connecting member 34a is meshed with the second rotating end 351a of the second connecting member 35a.

[0318] It can be understood that compared with the staggered tooth structure of the first gear portion 344a of the first connecting member 34a and the second gear portion 354a of the second connecting member 35a shown in Figures 16 and 17, the first gear portion 344a of the first connecting member 34a and the second gear portion 354a of the second connecting member 35a in this embodiment are longer in the X-axis direction, so that the structural strength of the first gear portion 344a of the first connecting member 34a and the second gear portion 354a of the second connecting member 35a is better and not easily damaged.

[0319] It can be understood that compared with the tooth structure of the first gear portion 344a of the first connecting member 34a and the second gear portion 354a of the second connecting member 35a as shown in Figures 32 and 33, the staggered tooth structure of the first gear portion 344a of the first connecting member 34a and the second gear portion 354a of the second connecting member 35a as shown in Figures 16 and 17 has a smaller thickness in the Z-axis direction, which is conducive to the thinning setting of the first button 3a.

[0320] The above text describes the structure of the first button 3a in detail in conjunction with the relevant drawings. The following text describes the structure of the second button 3b in detail in conjunction with the relevant drawings. It can be understood that most of the structures of the second button 3b in this embodiment are the same as the structures of the first button 3a. The basic design of the component structure of the second button 3b, the connection relationship design between the components, and other connection relationship designs other than components and assemblies can all refer to the relevant schemes of the first button 3a. At the same time, the second button 3b and the first button 3a are allowed to be slightly different in the detailed structure or position arrangement of the components. The details will not be repeated here. The technical content that the second button 3b has in common with the first button 3a will not be repeated here. The following text will focus on the differences between the second button 3b and the first button 3a.

[0321] Figure 34 is a partially exploded view of one embodiment of the second key 3b shown in Figure 2. Figure 35 is a partial cross-sectional view of one embodiment of the keyboard 100 shown in Figure 1 at line HH. Figure 36 is a partial cross-sectional view of one embodiment of the second key 3b of the keyboard 100 shown in Figure 35 in a triggered state.

[0322] As shown in Figures 34 to 36 , the second key 3b includes a second keycap 31b, a third connecting member 34b, a fourth connecting member 35b, and a second elastic member 36b. The basic structural design of the second keycap 31b, the third connecting member 34b, the fourth connecting member 35b, and the second elastic member 36b, as well as the design of the connections between the components and other connections between the components and the assembly, can all be referenced to the related schemes for the first keycap 31a, the first connecting member 34a, the second connecting member 35a, and the second elastic member 36b of the first key 3a. For example, the third connecting member 34b includes a first rotating end 341b and a first movable end 343b. The first rotating end 341b of the third connecting member 34b is rotatably connected to the circuit board 2, and the first movable end 343b of the third connecting member 34b is movably connected to the second keycap 31b. The fourth connecting member 35b includes a second rotating end 351b and a second movable end 353b. The second rotating end 351b of the fourth connecting member 35b is rotatably connected to the circuit board 2, and the second movable end 353b of the fourth connecting member 35b is movably connected to the second keycap 31b. The first rotating end 341b of the third connecting member 34b includes a first gear portion 344b, and the second rotating end 351b of the fourth connecting member 35b includes a second gear portion 354b. The first gear portion 344b of the third connecting member 34b meshes with the second gear portion 354b of the fourth connecting member 35b. It is understood that the structure of the first gear portion 344b of the third connecting member 34b and the second gear portion 354b of the fourth connecting member 35b is not limited to the structure shown in Figures 34 to 36, and the structure shown in Figure 16 may also be adopted. At this time, the first gear portion 344b of the third connecting member 34b and the second gear portion 354b of the fourth connecting member 35b may be arranged in a staggered meshing manner.

[0323] In this embodiment, the pitch circle diameter of the first gear portion 344b of the third connecting member 34b of the second key 3b is not equal to the pitch circle diameter of the second gear portion 354a of the fourth connecting member 35b. In other words, the ratio of the pitch circle diameter of the first gear portion 344b of the third connecting member 34b to the pitch circle diameter of the second gear portion 354a of the fourth connecting member 35b is not equal to 1. Consequently, when the first gear portion 344b of the third connecting member 34b meshes with the second gear portion 354b of the fourth connecting member 35b, the rotation angle of the third connecting member 34b and the rotation angle of the fourth connecting member 35b differ. In this case, the movement speed of the portion of the second keycap 31b connected to the third connecting member 34b differs from the movement speed of the portion of the second keycap 31b connected to the fourth connecting member 35b. When the second key 3b is in the activated state, the second keycap 31b is tilted relative to the circuit board 2. The angle A2 between the second central axis L2 of the second key 3b and the central axis L0 of the circuit board 2 is large. For example, A2 can satisfy the following: A2 ≥ 3°. In the foregoing description of Figures 15 to 33 , the pitch circle diameter of the first gear portion 344a of the first connector 34a of the first button 3a is equal to the pitch circle diameter of the second gear portion 354a of the second connector 35a of the first button 3a. That is, the ratio of the pitch circle diameter of the first gear portion 344a of the first connector 34a of the first button 3a to the pitch circle diameter of the second gear portion 354a of the second connector 35a of the first button 3a is 1. Thus, when the first gear portion 344a of the first connector 34a and the second gear portion 354a of the second connector 35a are engaged, the rotation angle of the first connector 34a and the rotation angle of the second connector 35a can be the same. At this point, regardless of whether the first button 3a is in an unpressed state or in an activated state, the angle between the first central axis L1 of the first button 3a and the circuit board 2 remains substantially constant. At this time, when the first button 3a is in the triggered state, the angle A1 between the first central axis L1 of the first button 3a and the central axis L0 of the circuit board 2 is relatively small. Therefore, when both the first button 3a and the second button 3b are in the triggered state, the angle A2 between the second central axis L2 of the second button 3b and the central axis L0 of the circuit board 2 is larger than the angle A1 between the first central axis L1 of the first button 3a and the central axis L0 of the circuit board 2, that is, A2 > A1. The angle b between the first central axis L1 of the first button 3a and the second central axis L2 of the second button 3b is also relatively large. For example, b satisfies the following: b ≥ 3°.

[0324] Exemplarily, the pitch circle diameter of the first gear portion 344b of the third connecting member 34b is smaller than the pitch circle diameter of the second gear portion 354a of the fourth connecting member 35b. Specifically, the ratio of the pitch circle diameter of the first gear portion 344b of the third connecting member 34b to the pitch circle diameter of the second gear portion 354a of the fourth connecting member 35b is less than 1. Thus, when the first gear portion 344b of the third connecting member 34b meshes with the second gear portion 354b of the fourth connecting member 35b, the rotation angle of the third connecting member 34b is greater than the rotation angle of the fourth connecting member 35b. Specifically, the first gear portion 344b of the third connecting member 34b is closer to the first key 3a than the second gear portion 354b of the fourth connecting member 35b. At this time, when both the first key 3a and the second key 3b are in the triggered state, the second keycap 31b of the second key 3b tilts toward the first key 3a. It is understood that by adjusting the ratio of the diameter of the pitch circle of the first gear portion 344b of the third connecting member 34b to the diameter of the pitch circle of the second gear portion 354a of the fourth connecting member 35b, different degrees of inclination of the second keycap 31b of the second key 3b can be achieved. In other words, when the difference between the diameter of the pitch circle of the first gear portion 344b of the third connecting member 34b and the diameter of the pitch circle of the second gear portion 354a of the fourth connecting member 35b is larger, the degree of inclination of the second keycap 31b of the second key 3b is greater.

[0325] It is understood that the pitch circle diameter of the first gear portion 344a of the first connecting member 34a of the first button 3a is the first diameter. The pitch circle diameter of the second gear portion 354a of the second connecting member 35a of the first button 3a is the second diameter. When the first diameter and the second diameter are not equal, the ratio of the maximum to the minimum of the first and second diameters is the first value. For example, the first diameter is 2 mm and the second diameter is 5 mm. Thus, the first diameter is the minimum value and the second diameter is the maximum value. In this case, the first value is the ratio of 5 to 2, or 2.5. When the first diameter and the second diameter are equal, the ratio of the first diameter to the second diameter is the first value. This embodiment is described using the example of the first diameter and the second diameter being equal (i.e., the first value is equal to 1). Furthermore, the pitch circle diameter of the first gear portion 344b of the third connecting member 34b of the second button 3b is the third diameter. The pitch circle diameter of the second gear portion 354a of the fourth connecting member 35b is the fourth diameter. The third diameter and the fourth diameter are not equal, and the ratio of the maximum to the minimum of the third and fourth diameters is a second value. For example, the third diameter is 2 mm and the fourth diameter is 6 mm. Thus, the third diameter is the minimum value, and the fourth diameter is the maximum value. In this case, the second value is the ratio of 6 to 2, or 3. In this embodiment, the second value is greater than the first value.

[0326] In this embodiment, by setting the second value to be greater than the first value, when both the first button 3a and the second button 3b are in the triggered state, the first keycap 31a of the first button 3a and the second keycap 31b of the second button 3b have different inclination angles relative to the circuit board 2, with the second keycap 31b of the second button 3b having a larger inclination angle than the first keycap 31a of the first button 3a. This increases the angle b between the first central axis L1 of the first button 3a and the second central axis L2 of the second button 3b, thereby achieving different orientations of the top surfaces 30a, 30b of the first button 3a and the second button 3b. In this case, when both the first button 3a and the second button 3b are in the triggered state, the configuration of the first button 3a and the second button 3b meets ergonomic principles and provides a better user experience. It is understood that the greater the difference between the second value and the first value, the greater the inclination angle of the second keycap 31b of the second button 3b compared to the first keycap 31a of the first button 3a. In this way, the included angle b between the first central axis L1 of the first button 3a and the second central axis L2 of the second button 3b increases. As the difference between the second value and the first value decreases, the inclination angles of the first keycap 31a of the first button 3a and the second keycap 31b of the second button 3b become closer. As a result, the included angle b between the first central axis L1 of the first button 3a and the second central axis L2 of the second button 3b decreases.

[0327] It can be understood that when the keyboard 100 includes a third key 3c, the structure of the third key 3c and its relationship with the structure of the first key 3a can refer to the structure of the second key 3b and its relationship with the structure of the first key 3a, so that when the first key 3a and the third key 3c are both in the triggered state, the top surface 30a of the first key 3a and the top surface 30c of the third key 3c are oriented differently.

[0328] As shown in FIG36 , the second movable end 353b of the fourth connector 35b further includes a stopper 3531b. The stopper 3531b protrudes from the bottom surface of the second body portion 358b of the second movable end 353b of the fourth connector 35b. The bottom surface of the second body portion 358b of the fourth connector 35b is the surface of the second body portion 358b of the fourth connector 35b that is away from the second keycap 31b.

[0329] It is understood that when the second key 3b is in the triggered state, the stopper 3531b can abut against the reinforcement plate 4, thereby maintaining the shape of the second keycap 31b on the one hand, and preventing the fourth connecting member 35b from being over-bent, which would cause the second gear portion 354b of the fourth connecting member 35b and the first gear portion 344b of the third connecting member 34b to break, thereby ensuring the reliability of the third connecting member 34b and the fourth connecting member 35b.
