Description

Technical Field

[0001] This application relates to the field of keyboards, and particularly to a keyboard and an electronic device. Background Art

[0002] With the development of technology and the demands of the electronic device market, the keyboard, as the main way of information input, has attracted more and more attention from manufacturers. In a traditional keyboard, all the keys move vertically up and down during pressing, and the inclination angle of each row of keys is the same. After long-term use, it is easy to cause wrist fatigue. In another traditional keyboard, although the pressing angles of each row of keys are different and the feel is good after long-term use, due to unreasonable structural settings, it causes waste of space, cannot be used on thin tablets or laptops, and the appearance is not tidy. Therefore, it is urgent to set up a keyboard that can not only conform to ergonomics, have a good feel after long-term use, but also improve the space utilization rate of the keyboard. Summary of the Invention

[0003] The purpose of this application is to provide a keyboard and an electronic device that can not only conform to ergonomics, have a good feel after long-term use, but also improve the space utilization rate of the keyboard.

[0004] In a first aspect, this application provides a keyboard. The keyboard includes a housing, a circuit board, and a plurality of keys. The circuit board is installed in the housing, and the plurality of keys are installed on the circuit board. The plurality of keys all include an unpressed state and a triggered state;

[0005] The plurality of keys include a first key and a second key. The first central axis of the first key is perpendicular to the top surface of the first key and passes through the center of the top surface of the first key. The second central axis of the second key is perpendicular to the top surface of the second key and passes through the center of the top surface of the second key;

[0006] When both the first key and the second key 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°.

[0007] When both the first key and the second key 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°.

[0008] It can be understood 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 solution where the top surfaces of the first button and 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 top surfaces of the first button and the second button have substantially the same orientation when both the first button and the second button are in the unpressed state, the occupied space of the first button and the second button in the Z-axis direction is relatively consistent. The first button and the second button 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.

[0009] In addition, since the top surfaces of the first button and the second button have substantially the same orientation 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.

[0010] It can be understood that when both the first button and the second button are in the triggered state, b satisfies: b≥M1, so that when both the first button and the second button are 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 both the first button and the second button are in the triggered state, the top surface of the first button and the top surface of the second button are intersecting (that is, not parallel), that is, the orientations of the top surface of the first button and the top surface of the second button are different. In this way, compared with the solution where the top surfaces of the first button and the second button have the same orientation when both the first button and the second button are in the triggered state, in this embodiment, since the top surfaces of the first button and the second button have different orientations, the first button and the second button can not only meet the user's tapping feel at different positions, but also solve the problem that the user's wrist gets fatigued due to the same bending degree at different positions. At this time, the setting method of the first button and the second button can meet the ergonomic theory, and the user experience is better.

[0011] In a possible implementation, when both the first button and the second button are in the unpressed state, the top surface of the first button is flush with the top surface of the second button. In this way, the occupied space of the first button and the second button in the Z-axis direction is relatively consistent, which is beneficial to the thin design of the keyboard.

[0012] 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 keys.

[0013] When both the first key and the second key are in the triggered state, the top surface of the second key inclines towards the first key, 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.

[0014] It can be understood that by setting that when both the first key and the second key are in the triggered state, the top surface of the second key inclines towards the first key, and A2 > A1, it is possible to prevent the user's wrist from getting easily fatigued when hitting different positions on the keyboard, thereby greatly improving the user experience.

[0015] In a possible implementation, A1 and A2 satisfy: 0° ≤ A1 < 3°, A2 ≥ 3°. In this way, on the one hand, it can ensure A2 > A1; on the other hand, since A1 can satisfy: 0° ≤ A1 < 3°, the first central axis of the first key is arranged substantially parallel to the central axis of the circuit board. At this time, the first key does not occupy much space in the Z-axis direction, which is conducive to improving the space utilization rate of the keyboard.

[0016] 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;

[0017] 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;

[0018] When both the first key and the third key are in the un-pressed state, the 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°;

[0019] When both the first key and the third key are in the triggered state, the angle between the third central axis and the first central axis is d, and d satisfies: d ≥ M2. For example, d ≥ 3°.

[0020] It can be understood that when the first button and the third button are both in the unpressed state, c satisfies: 0° ≤ c < M2, where 0° < M2 ≤ 10°. Thus, when the first button and the third button are both in the unpressed state, the first central axis of the first button is substantially parallel to the third central axis of the third button. At this time, when the first button and the third button are both in the unpressed state, the top surface of the first button and the top surface of the third button are substantially parallel, that is, the orientations of the top surface of the first button and the top surface of the third button are substantially the same. In addition, since when the first button and the second button are both in the unpressed state, 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, when the first button, the second button and the third button are all in the unpressed state, the orientations of the top surface of the first button, the top surface of the second button and the top surface of the third button are substantially the same. The occupied spaces of the first button, the second button and the third button in the Z-axis direction are relatively consistent. The first button, the second button and the third button 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.

[0021] In addition, since when the first button, the second button and the third button are all in the unpressed state, the orientations of the top surface of the first button, the top surface of the second button and the top surface of the third button are substantially the same, the appearance consistency of the first button, the second button and the third button is better, and the appearance of the keyboard is cleaner, which is beneficial to improving the user experience of the keyboard.

[0022] It can be understood 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 intersects with the third central axis of the third button. 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 intersect (that is, are not parallel), that is, the orientations of the top surface of the first button and the top surface of the third button are different. The first button and the third button can not only meet the user's tapping feel at different positions, but also solve the problem that the user's wrist gets fatigued due to the same bending degree at different positions. The setting method of the first button and the third button can meet the ergonomic theory, and the user experience is better.

[0023] Exemplarily, when the first button and the third button are both in the unpressed state, the top surface of the first button is flush with the top surface of the third button. In this way, the occupied spaces of the first button and the third button in the Z-axis direction are relatively consistent, which is beneficial to the thin design of the keyboard.

[0024] In a possible implementation, the third button is located on the side of the second button away from the first button;

[0025] When the first button, the second button and the third button are all in the trigger 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.

[0026] It can be understood that, since b and d satisfy: d>b, the inclination angle of the third button is greater than the inclination angle of the second button. At this time, when the first button is close to the user and the third button is set away from the user, or the first button is far from the user and the third button is set close to the user, the first button, the second button and the third button can not only satisfy the user's tapping feel at different distances, but also solve the problem of fatigue of the user's wrist due to the same bending degree at different distances. The setting method of the first button and the third button can meet the ergonomic theory and provide better user experience.

[0027] 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;

[0028] When the second button and the third button are both in the trigger 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, and A2 and A3 satisfy: A3>A2. In this way, the inclination angle of the third button is greater than the inclination angle of the second button. At this time, when the first button is close to the user and the third button is set away from the user, or the first button is far away from the user and the third button is set close to the user, the first button, the second button and the third button can not only satisfy the user's tapping feel at different distances, but also solve the problem of fatigue of the user's wrist due to the same degree of bending at different distances. The setting method of the first button and the third button can meet the ergonomic theory, and the user experience is better.

[0029] In a possible implementation, the third button is located on a side of the first button away from the second button;

[0030] When the first button and the third button are both in the trigger state, the top surface of the third button is inclined toward the first button, the angle between the first central axis and the central axis is A1, the angle between the third central axis and the central axis is A3, and A1 and A3 satisfy: A3>A1.

[0031] It can be understood that, since A1 and A3 satisfy: A3>A1, the inclination angle of the third button is greater than the inclination angle of the first button. At this time, when the third button is close to the user, or the third button is set far away from the user, the first button, the second button and the third button can not only satisfy the user's tapping feel at different distances, but also solve the problem of fatigue of the user's wrist due to the same bending degree at different distances. The setting method of the first button and the third button can meet the ergonomic theory, and the user experience is better.

[0032] In a possible implementation, the first key includes a first key cap, a first connecting member, and a second connecting member;

[0033] 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, the first movable end of the first connecting member is movably connected to the first key cap, 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 key cap;

[0034] 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 diameter of the pitch circle of the first gear portion of the first connecting member is a first diameter, and the diameter of the pitch circle of the second gear portion of the second connecting member is a second diameter, when the first diameter is not equal to the second diameter, 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 is equal to the second diameter, the ratio of the first diameter to the second diameter is a first value;

[0035] The second key comprises a second keycap, a third connecting member and a fourth connecting member, the third connecting member comprises 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 comprises 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;

[0036] 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, and 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.

[0037] It can be understood that the diameter of the pitch circle of the first gear part of the first connecting member of the first button is the first diameter. The diameter of the pitch circle of the second gear part of the second connecting member of the first button is the second diameter. Wherein, when the first diameter is not equal to the second diameter, the ratio of the maximum value to the minimum value of the first diameter and the second diameter is the first value. For example, the first diameter is 2 mm and the second diameter is 5 mm. In this way, the first diameter is the minimum value. The second diameter is the maximum value. At this time, the first value is the ratio of 5 to 2, that is, 2.5. When the first diameter is equal to the second diameter, the ratio of the first diameter to the second diameter is the first value. This embodiment is described by taking the first diameter and the second diameter as an example. In addition, the diameter of the pitch circle of the first gear part of the third connecting member of the second button is the third diameter. The diameter of the pitch circle of the second gear part of the fourth connecting member is the fourth diameter. The third diameter is not equal to the fourth diameter, and the ratio of the maximum value to the minimum value of the third diameter and the fourth diameter is the second value. For example, the third diameter is 2 mm and the fourth diameter is 6 mm. In this way, the third diameter is the minimum value. 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.

[0038] It is understandable that by setting the second value to be greater than the first value, when both the first button and the second button are in the trigger state, the first button and the second button have different inclination angles relative to the circuit board, and the inclination angle of the second button is greater than that of the first button. In this way, the angle b between the first central axis of the first button and the second central axis of the second button is larger, thereby achieving different orientations of the top surface of the first button and the top surface of the second button. At this time, when both the first button and the second button are in the trigger state, the setting mode of the first button and the second button can meet the ergonomic theory, and the user experience is better. It is understandable that when the difference between the second value and the first value is greater, the inclination angle of the second button is greater than that of the first button. In this way, the angle b between the first central axis of the first button and the second central axis of the second button is greater. When the difference between the second value and the first value is smaller, the inclination angle of the first button is closer to the inclination angle of the second button. In this way, the angle b between the first central axis of the first button and the second central axis of the second button is smaller.

[0039] In a possible implementation, the first diameter is equal to the second diameter, and the third diameter is smaller than the fourth diameter.

[0040] 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;

[0041] 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;

[0042] 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.

[0043] 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.

[0044] In a 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, the first sub-gear portion of the second connecting member includes a first tooth and a second tooth, and 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;

[0045] The first tooth of the first connecting member meshes with the first tooth of the second connecting member, the second tooth of the first connecting member meshes 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 crosswise.

[0046] 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;

[0047] The first tooth of the first connecting member is located between the first tooth and the second tooth of the second connecting member.

[0048] It can be understood that by setting the connecting line between the first tooth and the second tooth of the first connecting member and the connecting line between the first tooth and the second tooth of the second connecting member to be cross-arranged, the first gear part of the first connecting member and the second gear part of the second connecting member are arranged in a staggered structure. In this way, in the Z-axis direction, the thickness of the first gear part of the first connecting member and the second gear part of the second connecting member is smaller, which is conducive to the thinning of the first button.

[0049] 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;

[0050] The second connecting member includes a second connecting section, and the second connecting section of the second connecting member connects the second rotating end of the second connecting member and the second movable end of the second connecting member;

[0051] The first button also 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.

[0052] 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 in 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 in 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.

[0053] 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;

[0054] When the first button is in a triggered state, the first center line is arranged at an angle with 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.

[0055] It is understandable that, since the first center line of the first elastic member is not parallel to the top surface of the circuit board, the elastic force applied by the first elastic member to the first connecting member and the second connecting member can generate a component force in the positive direction of the Z axis. At this time, the component force can make the first rotating end of the first connecting member rotate relative to the first fixing seat and the second fixing seat, and the second rotating end of the second connecting member rotate relative to the first fixing seat and the second fixing seat, so that the first button can be switched from the triggered state to the unpressed state.

[0056] In a possible implementation, the first movable end of the first connecting member is slidably connected to the first key cap and relatively rotates;

[0057] The center of rotation of the first connecting member relative to the circuit board is the first rotation center, the center of rotation of the first connecting member relative to the first key cap is the second rotation center, the distance between the first rotation center and the bottom surface of the circuit board is the first height H1, and the distance between the second rotation center and the bottom surface of the circuit board is the second height H2, wherein the bottom surface of the circuit board is the surface of the circuit board facing away from the key;

[0058] When the first button is in the triggered state, H1 and H2 satisfy: H1 < H2.

[0059] 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 un-pressed state.

[0060] 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;

[0061] 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 face 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 face of the first gear portion of the first connecting member. The first end face and the second end face of the first gear portion of the first connecting member are arranged back to back;

[0062] 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.

[0063] 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.

[0064] In a possible implementation, the first rotating end of the first connecting member includes a first stopping portion, and the first stopping portion of the first connecting member protrudes from the first end face of the first gear portion of the first connecting member, and the first fixed seat is provided with a first stopping groove;

[0065] When the first button is in the un-pressed state, at least a part of the first stopping portion of the first connecting member is located in the first stopping groove and abuts against the bottom wall of the first stopping groove;

[0066] When the first button is in a triggered state, the first stop portion is separately arranged from the bottom wall of the first stop groove.

[0067] It can be understood that the bottom wall of the first stop 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.

[0068] In a possible implementation manner, 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.

[0069] In a possible implementation, the circuit board includes a plurality of trigger terminals;

[0070] The keyboard also includes a plurality of triggering members, which are located between the plurality of keys and the plurality of triggering ends in a one-to-one correspondence. When the keys are in a triggering state, the keys squeeze the triggering ends of the circuit board through the triggering members, and the circuit board generates an electrical signal.

[0071] 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.

[0072] In a possible implementation, multiple triggering members are fixed on multiple triggering ends in a one-to-one correspondence, so that the triggering member can accurately trigger the triggering end of the circuit board, that is, it is avoided that when the key presses the triggering member, the triggering member cannot be accurately pressed to the triggering end.

[0073] In a possible implementation, the trigger member is an elastic member, and when the key is in the trigger state, the trigger member is in a compressed state.

[0074] It can be understood that when the first key is switched from the triggered state to the unpressed state, since the first keycap is no longer subjected to the pressing force, the elastic force applied by the trigger member to 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 apply a force to the first connecting member and the second connecting member, so that the first rotating end of the first connecting member can rotate relative to the first fixing seat and the second fixing seat, and the second rotating end of the second connecting member can rotate relative to the first fixing seat and the second fixing seat. In this way, the first key can be switched from the triggered state to the unpressed state.

[0075] In a second aspect, the present application provides an electronic device, which includes a display device and the keyboard according to the first aspect, wherein the keyboard is communicatively connected to the display device.

[0076] It is understandable that since the keyboard can be ergonomic, have a good feel for long-term use, and can improve the utilization rate of keyboard space, the user experience of the electronic device is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0115] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0116] In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "install", "connect", "connect", and "connect" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be an electrical connection or a mechanical connection. Among them, "fixed connection" means that the relative position relationship after connection does not change. "Active connection" means that the relative position relationship after connection can change. "Rotational connection" means that the two components are connected to each other and can rotate relative to each other after connection. "Sliding connection" means that the two components are connected to each other and can slide relative to each other after connection. In addition, the two components are obtained by an integrated molding process. The integrated structure means that in the process of forming one of the two components, the component is connected to the other component, and the two components do not need to be connected together by reprocessing (such as bonding, welding, snap connection, screw connection). In order to make the basic parameters of the gear have a unified certainty, a circle must be specified as the basis for calculation in the gear calculation. 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 pitch to π.

[0117] 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 referenced to the directions of the drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0118] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0119] Figure 1 It is a schematic diagram of the structure of an electronic device 1000 provided in accordance with an embodiment of the present application.

[0120] like Figure 1 As shown, 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.

[0121] Exemplarily, the electronic device 1000 includes a keyboard 100 and a display device 200. The keyboard 100 can be used as an input device for the display device 200. The 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.

[0122] 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 realizing signal transmission in an airless / non-contact manner. For example, multiple components can use short-range communication technology (for example, Bluetooth, wireless LAN (WiFi, Wireless Fidelity) or short-range communication (NFC, Near Field Communication), etc.).

[0123] For ease of description, illustratively, the thickness direction of the keyboard 100 is defined as the Z-axis direction, and the width direction of the keyboard 100 is defined as the Y-axis direction. The direction perpendicular to the Y-axis direction and the Z-axis direction is the X-axis direction, that is, the length direction of the keyboard 100 is the X-axis. It is understandable that the coordinate system of the keyboard 100 can also be flexibly set according to specific needs.

[0124] Figure 2 yes Figure 1 The keyboard 100 is shown in a partially exploded schematic diagram in one embodiment.

[0125] like Figure 1 and Figure 2 As shown, the keyboard 100 includes a housing 1, a circuit board 2 and a plurality of keys 3. It is understandable that Figure 1 and Figure 2 A certain number of keys 3 are only provided schematically, but the present application does not make any specific limitation on the specific number, specific size, etc. of the keys 3.

[0126] In one embodiment, the housing 1 includes a top plate 11 and a bottom plate 12 that are relatively arranged, a distal side plate 13 (also called a first side plate 13) and a proximal side plate 14 (also called a second side plate 14) that are relatively arranged, and a left side plate 15 (also called a third side plate 15) and a right side plate 16 (also called a fourth side plate 16) that are relatively arranged. Among them, the distal side plate 13 and the proximal side plate 14 are connected between the top plate 11 and the bottom plate 12. The left side plate 15 and the right side plate 16 are connected between the top plate 11 and the bottom plate 12, and are also connected between the distal side plate 13 and the proximal side plate 14. It can be understood that the distal side plate 13 of the housing 1 can be the side plate of the housing 1 away from the user during the user's use of the keyboard 100. The proximal side plate 14 of the housing 1 can be the side plate of the housing 1 close to the user during the user's use of the keyboard 100. The left side plate 15 of the housing 1 can be the side plate of the housing 1 close to the user's left hand during the user's use of 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 .

[0127] 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 shell 1 may enclose an accommodation space 17 .

[0128] like Figure 1 and Figure 2 As shown, the top plate 11 of the housing 1 is provided with a plurality of through holes 18. The through holes 18 are connected to the accommodating space 17. It is to be understood that the present application does not specifically limit the size, shape, and arrangement of the through holes 18. In addition, the size and shape of each through hole 18 may be the same or different.

[0129] It is understandable that, although the foregoing text introduces 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.

[0130] like Figure 2 As shown, the circuit board 2 includes a plurality of trigger terminals 21 . Figure 2 The trigger terminal 21 is schematically shown by the dotted box. The trigger terminal 21 is used to make the circuit board 2 generate an electrical signal when the button 3 is pressed, and the information or instructions composed of the electrical signal can be transmitted to the display device 200. It is understandable that the size, shape, and arrangement of the trigger terminal 21 are not specifically limited in this application. 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.

[0131] Figure 3 yes Figure 1 The keyboard 100 is shown as a partial cross-sectional schematic diagram of an embodiment at line AA.

[0132] See also Figure 3 , and combined with Figure 1 and Figure 2 As shown, the circuit board 2 is located in the accommodating space 17 of the housing 1 and is mounted on the housing 1. For example, the circuit board 2 can be connected to the top plate 11 of the housing 1 by welding, screw locking, bonding, etc. In other embodiments, the circuit board 2 can also be fixed to the bottom plate 12 of the housing 1.

[0133] In one implementation, the multiple triggering ends 21 of the circuit board 2 may be disposed in a one-to-one correspondence with the multiple through holes 18 of the housing 1 .

[0134] See also Figure 3 , and combined with Figure 1 and Figure 2 As shown, exemplarily, a plurality of buttons 3 are mounted on the circuit board 2. A portion of the button 3 may be located in the through hole 18, and a portion may be located outside the housing 1. In other embodiments, the button 3 may also extend from the accommodating space 17 through the through hole 18 to the outside of the housing 1. In this case, a portion of the button 3 may be located in the accommodating space 17, a portion may be located in the through hole 18, and a portion may be located outside the housing 1.

[0135] It is understandable that the plurality of buttons 3 include an unpressed state (also referred to as a start state) and a triggered state (also referred to as a stop state). Figures 1 to 3The structure of the button 3 in the unpressed state is schematically shown. 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. This application does not specifically limit this.

[0136] 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.

[0137] like Figures 1 to 3 As shown, the plurality of keys 3 include a first key 3a and a second key 3b. It can be understood that Figures 1 to 3 It is shown that the first button 3a and the second button 3b are arranged along the positive direction of the Y axis. In other embodiments, the first button 3a and the second button 3b can be arranged arbitrarily on the XY plane. For example, the first button 3a and the second button 3b can be arranged along the negative direction of the Y axis, the positive direction of the X axis, or the negative direction of the X axis. This application does not make any specific restrictions.

[0138] Figure 4 yes Figure 1 The keyboard 100 shown is a schematic diagram of a partial structure in one embodiment.

[0139] like Figure 4 As shown, 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 plane 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.

[0140] like Figure 4 As shown, 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 plane 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.

[0141] like Figure 4As shown, when both the first button 3a and the second button 3b are in the unpressed 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 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 indicate the included angle a, Figure 4 by moving the first central axis L1 and the second central axis L2 to the tops of the first button 3a and the second button 3b and combining them to form the included angle a. For similar settings that may appear below, the explanations here can be referred to. Specifically, it will not be elaborated further below. 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 below can also be referred to the explanations here. Specifically, it will not be elaborated further below.

[0142] It can be understood that by setting that when both the first button 3a and the second button 3b are in the unpressed state, a satisfies: 0° ≤ a < M1; where 0° < M1 ≤ 10°, so that when both the first button 3a and the second button 3b are 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 both the first button 3a and the second button 3b are 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 scheme where the top surface 30a of the first button 3a and the top surface 30b of the second button 3b have different orientations when both the first button 3a and the second button 3b are 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 both the first button 3a and the second button 3b are in the unpressed state, the occupied spaces of the first button 3a and the second button 3b in the Z-axis direction are 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.

[0143] 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 both the first button 3a and the second button 3b are 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 neater, which is beneficial to improving the user experience of the keyboard 100.

[0144] For example, when the first key 3a and the second key 3b are both in an unpressed state, the top surface 30a of the first key 3a is flush with the top surface 30b of the second key 3b. In this way, the occupied spaces of the first key 3a and the second key 3b in the Z-axis direction are relatively consistent, which is conducive to the thinning of the keyboard 100.

[0145] Figure 5 yes Figure 4 The keyboard 100 shown is a partial structural diagram of an implementation manner when in a triggered state.

[0146] like Figure 5 As shown, when the first button 3a and the second button 3b are both in the trigger state, the 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°.

[0147] It can be understood that, by setting that when the first button 3a and the second button 3b are both in the triggered state, b satisfies: b≥M1, so that when the first button 3a and the second button 3b are both 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 are intersectingly arranged. At this time, when the first button 3a and the second button 3b are both in the triggered state, the top surface 30a of the first button 3a and the top surface 30b of the second button 3b are intersectingly arranged (that is, not parallelly arranged), that is, the top surface 30a of the first button 3a and the top surface 30b of the second button 3b are in different directions. In this way, compared with the solution in which the top surface 30a of the first button 3a and the top surface 30b of the second button 3b face the same direction when both the first button 3a and the second button 3b are in the trigger state, in this embodiment, since the top surface 30a of the first button 3a and the top surface 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 fatigue of the user's wrist due to the same bending degree at different positions. At this time, the setting method of the first button 3a and the second button 3b can meet the ergonomic theory and provide better user experience.

[0148] It is understandable that when the first button 3a and the second button 3b are both in the trigger state, the orientation of the top surface 30a of the first button 3a and the top surface 30b of the second button 3b can be set in a variety of ways, which will be described in detail below with reference to the relevant drawings.

[0149] Figure 6 yes Figure 1 The keyboard 100 shown is a partially exploded schematic diagram of an embodiment when in a triggered state.

[0150] like Figure 6As shown, 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 with the first button 3a, the second button 3b is disposed closer to the distal side plate 13 of the housing 1.

[0151] In one embodiment, when the first button 3a and the second button 3b are both in the trigger state, the top surface 30b of the second button 3b is inclined toward the direction close to 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. 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.

[0152] It can be understood that, by setting that when the first button 3a and the second button 3b are 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 is not prone to fatigue problems when typing the key 3 away from the user on the keyboard 100, thereby greatly improving the user experience.

[0153] In one embodiment, A1 can satisfy: 0°≤A1<3°. A2 can satisfy: A2≥3°. In this way, on the one hand, A2>A1 can be ensured; 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 will not occupy much space in the Z-axis direction, which is conducive to improving the space utilization of the keyboard 100.

[0154] In other implementations, A1 may also satisfy: A1 ≥ 3°. Specifically, it may be flexibly set according to requirements.

[0155] Figure 7 yes Figure 1 The keyboard 100 shown is a partially exploded schematic diagram of another embodiment when in a triggered state.

[0156] like Figure 7 As shown, 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 with the first button 3a, the second button 3b is disposed closer to the proximal side plate 14 of the housing 1.

[0157] In one embodiment, when the first button 3a and the second button 3b are both in a triggered state, the top surface 30b of the second button 3b is inclined toward the direction close to 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.

[0158] 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 is not prone to wrist fatigue when typing the key 3 close to the user on the keyboard 100, thereby greatly improving the user experience.

[0159] In one embodiment, A1 can satisfy: 0°≤A1<3°. A2 can satisfy: A2≥3°. In this way, on the one hand, A2>A1 can be ensured; 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 will not occupy much space in the Z-axis direction, which is conducive to improving the space utilization of the keyboard 100.

[0160] In other implementations, A1 may also satisfy: A1 ≥ 3°. Specifically, it may be flexibly set according to requirements.

[0161] Figure 8 yes Figure 1 The keyboard 100 shown is a partial structural schematic diagram in another embodiment.

[0162] like Figure 8 As shown, illustratively, the plurality of buttons 3 may further include a third button 3c. The third button 3c is spaced apart from the first button 3a and the second button 3b.

[0163] like Figure 8 As shown, 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 plane 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.

[0164] like Figure 8As shown, when both the first button 3a and the third button 3c are in the unpressed state, the angle between the third central axis L3 of the third button 3c and the first central axis L1 of the first button 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°.

[0165] It can be understood that by setting that when both the first button 3a and the third button 3c are in the unpressed state, c satisfies: 0° ≤ c < M2, where 0° < M2 ≤ 10°, so that when both the first button 3a and the third button 3c are in the unpressed state, the first central axis L1 of the first button 3a and the third central axis L3 of the third button 3c are substantially parallel. At this time, when both the first button 3a and the third button 3c are in the unpressed state, the top surface 30a of the first button 3a and the top surface 30c of the third button 3c are substantially parallel, that is, the orientations of the top surface 30a of the first button 3a and the top surface 30c of the third button 3c are substantially the same. In addition, since when both the first button 3a and the second button 3b are in the unpressed state, 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, when the first button 3a, the second button 3b and the third button 3c are all in the unpressed state, the orientations of the top surface 30a of the first button 3a, the top surface 30b of the second button 3b and the top surface 30c of the third button 3c are substantially the same. The occupied spaces of the first button 3a, the second button 3b and the third button 3c in the Z-axis direction are relatively consistent. The first button 3a, the second button 3b and the third button 3c 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 100.

[0166] In addition, since when the first button 3a, the second button 3b and the third button 3c are all in the unpressed state, the orientations of the top surface 30a of the first button 3a, the top surface 30b of the second button 3b and the top surface 30c of the third button 3c are substantially the same, the appearance consistency of the first button 3a, the second button 3b and the third button 3c is better, and the appearance of the keyboard 100 is cleaner and more beautiful, which is beneficial to improving the user experience of the keyboard 100.

[0167] Exemplarily, when both the first button 3a and the third button 3c are in the unpressed state, the top surface 30a of the first button 3a is flush with the top surface 30c of the third button 3c. In this way, the occupied spaces of the first button 3a and the third button 3c in the Z-axis direction are relatively consistent, which is beneficial to the thin design of the keyboard 100.

[0168] Fig. 9 Yes Figure 8The keyboard 100 shown is a partial structural diagram of an implementation manner when in a triggered state.

[0169] like Fig. 9 As shown, when the first button 3a and the third button 3c are both in the trigger state, the angle between the first central axis L1 of the first button 3a and the third central axis L3 of the third button 3c is d, and d satisfies: d≥M2. For example, d≥3°.

[0170] It can be understood that, by setting that when the first button 3a and the third button 3c are both in the trigger state, d satisfies: d≥M2, so that when the first button 3a and the third button 3c are both in the trigger 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 trigger 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 bending degree at different positions. The setting method of the first button 3a and the third button 3c can meet the ergonomic theory, and the user experience is better.

[0171] 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.

[0172] It is understandable that when the second button 3b and the third button 3c are both in the trigger state, the angle between the second central axis L2 of the second button 3b and the third central axis L3 of the third button 3c is e, and e can satisfy: e≥3°, or can satisfy: 0°≤e<3°. This application does not make any specific limitation.

[0173] The following will describe in detail several arrangements of the third button 3c, the first button 3a and the second button 3b in conjunction with the relevant drawings.

[0174] Fig.10 yes Figure 1 The keyboard 100 shown is a partially exploded schematic diagram of another embodiment when in a triggered state.

[0175] like Fig.10As shown, the third button 3c is located on the side of the second button 3b away from the first button 3a, that is, the second button 3b is located between the first button 3a and the third button 3c. In addition, the third button 3c is located between the second button 3b and the distal side plate 13 of the housing 1. In other words, compared with the first button 3a and the second button 3b, the third button 3c is arranged closer to the distal side plate 13 of the housing 1.

[0176] like Fig.10 As shown, when the first button 3a, the second button 3b and the third button 3c are all in the trigger state, the top surface 30b of the second button 3b and the top surface 30c of the third button 3c are both inclined in the direction close to 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. In addition, 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, that is, A3>A2. In this way, when the user presses the third button 3c, the user's wrist is not prone to fatigue, thereby greatly improving the user experience. The arrangement of the first button 3a, the second button 3b and the third button 3c can meet the ergonomic theory and provide better user experience.

[0177] Fig.11 yes Figure 1 The keyboard 100 shown is a partially exploded schematic diagram of another embodiment when in a triggered state.

[0178] like Fig.11 As shown, 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 plate 13 of the housing 1. The third button 3c is located between the first button 3a and the proximal side plate 14 of the housing 1. In other words, compared with the first button 3a, the second button 3b is arranged closer to the distal side plate 13 of the housing 1. Compared with the first button 3a, the third button 3c is arranged closer to the proximal side plate 14 of the housing 1.

[0179] In one embodiment, when the first button 3a and the second button 3b are both in a triggered state, the top surface 30b of the second button 3b is inclined toward the direction close to 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.

[0180] 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 second button 3b away from the user on the keyboard 100, thereby greatly improving the user experience.

[0181] In one embodiment, when the first button 3a and the third button 3c are both in a 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.

[0182] 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, when the user taps the third button 3c close to the user on the keyboard 100, the wrist will not feel fatigued due to the large degree of bending, thereby greatly improving the user experience.

[0183] 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 may 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.

[0184] It is understandable that, when the second button 3b and the third button 3c are both in the trigger state, the top surface 30b of the second button 3b is inclined toward the direction close to the first button 3a, and the top surface 30c of the third button 3c is inclined toward the direction close to the first button 3a, so that the top surface 30b of the second button 3b and the top surface 30c of the third button 3c face different directions. In this way, through the cooperation between the second button 3b and the third button 3c, it 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 bending degree at different positions. The setting method of the first button 3a and the third button 3c can meet the ergonomic theory and provide better user experience.

[0185] It is understandable that the multiple keys 3 may also include a fourth key, a fifth key, ..., an Mth key. Where M≥4. Relative to the first key 3a, the Mth key may be arranged closer to the distal side plate 13, or closer to the proximal side plate 14. For example, the Mth key may refer to the arrangement of the third key 3c. Specifically, it may be flexibly arranged according to requirements. In this way, more keys 3 of the keyboard 100 may be arranged at different angles.

[0186] Fig.12 yes Figure 1 The keyboard 100 is shown in a partially exploded view in another embodiment. Fig.13 yes Figure 1 The keyboard 100 shown is a partial cross-sectional schematic diagram of another embodiment at line AA.

[0187] like Fig.12 and Fig.13 As shown, the keyboard 100 further includes a plurality of trigger members 5. The trigger member 5 may be an elastic member, such as a rubber cap, a spring or a spring, etc. In other embodiments, the trigger member 5 may also be a structural member in other forms.

[0188] The plurality of trigger members 5 are located between the plurality of buttons 3 and the plurality of trigger ends 21 in a one-to-one correspondence. For example, one trigger member 5 is located between one button 3 and one trigger end 21. It is understandable that by pressing the button 3, the button 3 squeezes the trigger member 5, the trigger member 5 is deformed, and squeezes the trigger end 21 of the circuit board 2, so that the circuit board 2 generates an electrical signal.

[0189] In one embodiment, a plurality of trigger members 5 are fixed on a plurality of trigger ends 21 on the circuit board 2 in a one-to-one correspondence. In this way, it can be ensured that the trigger member 5 accurately triggers the trigger end 21 of the circuit board 2, that is, it is prevented that when the button 3 squeezes the trigger member 5, the trigger member 5 cannot accurately squeeze the trigger end 21. In other embodiments, a plurality of trigger members 5 can also be fixed on the button 3, and the plurality of trigger members 5 are arranged relative to the plurality of trigger ends 21 in a one-to-one correspondence. When the button 3 is pressed, the button 3 can drive the trigger member 5 to move, and the trigger member 5 squeezes the trigger end 21 of the circuit board 2, so that the circuit board 2 generates an electrical signal.

[0190] like Fig.12 and Fig.13 As shown, exemplarily, the keyboard 100 further includes a reinforcing plate 4. The reinforcing plate 4 can be a steel sheet, an aluminum sheet, a titanium alloy sheet, or the like.

[0191] Exemplarily, the reinforcing plate 4 can be fixed on the surface of the circuit board 2 facing the key 3. The reinforcing plate 4 can be used to improve the strength of the circuit board 2. The reinforcing plate 4 is provided with a plurality of avoidance holes 41. The plurality of avoidance holes 41 are arranged one-to-one 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, the plurality of trigger members 5 can also be fixed on the reinforcing plate 4, and the plurality of trigger members 5 are arranged one-to-one with the plurality of trigger ends 21 through the avoidance holes 41.

[0192] In other embodiments, the reinforcing plate 4 may 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 member 5. The reinforcing plate 4 may not be provided with the avoidance hole 41.

[0193] Fig.14A yes Figure 1 A partial structural schematic diagram of another embodiment of the keyboard 100 is shown. Fig. 14B yes Fig.14A The structure diagram of an implementation mode of the first fixing seat 32 and the second fixing seat 33 shown in another angle.

[0194] like Fig.14A and Fig. 14B As shown, the keyboard 100 further includes a plurality of first fixing seats 32 and a plurality of second fixing seats 33 .

[0195] 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.

[0196] like Fig.14A and Fig. 14B As shown, the first fixed seat 32 may be provided with a first rotation axis groove 325 and a second rotation axis groove 326 which are arranged at intervals. Exemplarily, the first rotation axis groove 325 and the second rotation axis groove 326 may penetrate the first top surface 323 and the first side surface 321 of the first fixed seat 32. In other embodiments, the first rotation axis groove 325 and the second rotation axis groove 326 may also penetrate the second side surface 322 of the first fixed seat 32.

[0197] like Fig.14A and Fig. 14B As shown, the first fixing seat 32 is provided with a first stop groove 327. The first stop groove 327 may be located between the first shaft groove 325 and the second shaft groove 326. Exemplarily, the first stop groove 327 may pass through the first top surface 323 and the first side surface 321 of the first fixing seat 32.

[0198] It is understandable that the second fixed seat 33 and the first fixed seat 32 of this embodiment can be the same or similar structure, symmetrical or partially symmetrical structure, or different structure. In this embodiment, the second fixed seat 33 and the first fixed seat 32 have the same structure, and the basic design of the component structure of the second fixed seat 33, the connection relationship design between the components, and other connection relationship designs outside the components and assemblies can all refer to the relevant schemes of the first fixed seat 32. For example, the second fixed seat 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 fixed seat 33 and the first fixed seat 32 are allowed to be slightly different in the detailed structure or position arrangement of the components. The details will not be repeated here.

[0199] like Fig.14A and Fig. 14B As shown, a plurality of first fixing seats 32 and a plurality of second fixing seats 33 are disposed on both sides of a plurality of triggering ends 21 in a one-to-one correspondence. In other words, one first fixing seat 32 and one second fixing seat 33 are disposed on both sides of one triggering end 21.

[0200] Exemplarily, the first fixing seat 32 and the second fixing seat 33 are fixed on the reinforcing plate 4. A plurality of first fixing seats 32 and a plurality of second fixing seats 33 are arranged one by one on both sides of the plurality of avoidance holes 41. At this time, the first fixing seat 32 and the second fixing seat 33 can be fixed on the circuit board 2 through the reinforcing plate 4.

[0201] Exemplarily, the first fixing seat 32 and the second fixing seat 33 may 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 may also form an integral structure with the reinforcing plate 4.

[0202] 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. The present application does not make any specific limitation.

[0203] The above text specifically describes the state of the button 3 in the unpressed state and the triggered state, and the arrangement of the multiple buttons 3 in combination with the relevant drawings. The following text specifically describes the structure of the button 3 in combination with the relevant drawings.

[0204] Fig.15 yes Figure 2 The first button 3 a is shown in a partially exploded view in one embodiment.

[0205] like Fig.15As shown, the first key 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 can be a spring, a spring sheet or other elastic structural member. The number of the first elastic members 36a can be two. It is understood that the number, size and shape of the first elastic members 36a are not specifically limited in this application.

[0206] Fig.16 yes Fig.15 The structure diagram of the first connecting member 34a and the second connecting member 35a shown is at another angle.

[0207] like Fig.16 As shown, the first connecting member 34a includes a first rotating end 341a, a first connecting section 342a and a first movable end 343a which are connected in sequence.

[0208] Exemplarily, the first rotating end 341a of the first connecting member 34a includes a first gear portion 344a, a first rotating portion 345a, a second rotating portion 346a and a first stopping portion 347a.

[0209] Exemplarily, the first gear portion 344a of the first connecting member 34a includes a first end surface 3441a and a second end surface 3442a that are arranged in opposite directions.

[0210] For example, the first rotating portion 345a and the second rotating portion 346a of the first connecting member 34a may be block structures. The first rotating portion 345a of the first connecting member 34a is convexly disposed on the first end surface 3441a of the first gear portion 344a. The second rotating portion 346a of the first connecting member 34a is convexly disposed on the second end surface 3442a of the first gear portion 344a.

[0211] Exemplarily, the first stop portion 347a of the first connecting member 34a may be a block-shaped structure. The first stop portion 347a of the first connecting member 34a is convexly disposed on the first end surface 3441a of the first gear portion 344a, and is spaced apart from the first rotating portion 345a of the first connecting member 34a. In one embodiment, the first stop portion 347a of the first connecting member 34a is located on a side of the first rotating portion 345a of the first connecting member 34a away from the first movable end 343a of the first connecting member 34a.

[0212] like Fig.16 As shown, illustratively, the first connecting member 34a is provided with a first avoidance hole 3421a. The first avoidance hole 3421a can extend from the first rotating 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 can also be only provided at the first rotating end 341a of the first connecting member 34a.

[0213] 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 arranged at intervals. The first rotating portion 345a is convexly arranged on the surface of the first sub-gear portion 3443a away from the second sub-gear portion 3444a. The second rotating portion 346a is convexly arranged on the surface of the second sub-gear portion 3444a away from the first sub-gear portion 3443a.

[0214] Exemplarily, 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.

[0215] 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 will not be described in detail here.

[0216] like Fig.16 As shown, the first connecting section 342a of the first connecting member 34a includes a first connecting shaft 3422a. The number of the first connecting shafts 3422a can be two. The number of the first connecting shafts 3422a can be the same as the number of the 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.

[0217] Exemplarily, the first connecting section 342a of the first connecting member 34a is provided with a first mounting hole 3423a. The first mounting hole 3423a and the first avoidance hole 3421a are arranged at intervals. The portion between the first mounting hole 3423a and the first avoidance hole 3421a can be used to form the first connecting shaft 3422a.

[0218] like Fig.16 As shown, the first movable end 343a of the first connecting member 34a includes a first main body portion 348a, a first movable portion 3491a and a second movable portion 3492a.

[0221] like Fig.16 As shown, the second connecting member 35a includes a second rotating end 351a, a second connecting section 352a and a second movable end 353a which are connected in sequence.

[0222] Exemplarily, 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 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.

[0223] Illustratively, the second gear portion 354a of the second connecting member 35a includes a first end surface 3541a and a second end surface 3542a that are arranged in opposite directions.

[0224] Exemplarily, the third rotating portion 355a and the fourth rotating portion 356a of the second connecting member 35a may be block structures. The third rotating portion 355a of the second connecting member 35a is convexly disposed on the first end surface 3541a of the second gear portion 354a. The fourth rotating portion 356a of the second connecting member 35a is convexly disposed on 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 may also be through-hole structures.

[0225] Exemplarily, the second stop portion 357a of the second connecting member 35a can be a block-shaped structure. The second stop portion 357a of the second connecting member 35a is convexly arranged on the second end surface 3542a of the second gear portion 354a, and is spaced apart from the fourth rotating portion 356a of the second connecting member 35a. In one embodiment, the second stop portion 357a of the second connecting member 35a is located on a side of the fourth rotating portion 356a of the second connecting member 35a away from the second movable end 353a of the second connecting member 35a.

[0226] like Fig.16 As shown, illustratively, the second connecting member 35a is 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 only provided at the second rotation end 351a of the second connecting member 35a.

[0227] 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 arranged at intervals. The third rotating portion 355a is convexly arranged on the surface of the first sub-gear portion 3543a away from the second sub-gear portion 3544a. The fourth rotating portion 356a is convexly arranged on the surface of the second sub-gear portion 3544a away from the first sub-gear portion 3543a.

[0228] 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 close to the second sub-gear portion 3544a. The second tooth 3546a and the first tooth 3545a have a height difference. In other words, the first tooth 3545a and the second tooth 3546a of the second connecting member 35a are staggered in the thickness direction of the second connecting member 35a.

[0229] For example, the structure of the second sub-gear portion 3544a of the second connecting member 35a can refer to the structure of the first sub-gear portion 3543a of the second connecting member 35a, and the details will not be repeated here.

[0230] like Fig.16 As shown, the second connecting section 352a of the second connecting member 35a includes a second connecting shaft 3522a. The number of the second connecting shafts 3522a can be two. The number of the second connecting shafts 3522a can be the same as the number of the 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.

[0231] Exemplarily, the second connecting section 352a of the second connecting member 35a is provided with a second mounting hole 3523a. The second mounting hole 3523a and the second avoidance hole 3521a are arranged at intervals. The portion between the second mounting hole 3523a and the second avoidance hole 3521a can be used to form a second connecting shaft 3522a.

[0232] like Fig.16 As shown, the second movable end 353a of the second connecting member 35a includes a second body portion 358a, a third movable portion 3591a and a fourth movable portion 3592a.

[0233] For example, the second body portion 358a of the third movable end 353a may be plate-shaped. The second body portion 358a includes a first side surface 3581a and a second side surface 3582a which are arranged opposite to each other.

[0234] Exemplarily, the third movable portion 3591a and the fourth movable portion 3592a may be block structures. The third movable portion 3591a is protruded from the first side surface 3581a of the second body portion 358a. The fourth movable portion 3592a is protruded from the second side surface 3582a of the second body portion 358a.

[0235] It is understandable that the second connecting member 35a and the first connecting member 34a of this embodiment can be the same or similar structure, symmetrical or partially symmetrical structure, or different structure. In this embodiment, the second connecting member 35a and the first connecting member 34a have the same structure, and the basic design of the component structure of the second connecting member 35a, the connection relationship design between the components, and the design of other connection relationships outside the components and assemblies can all refer to the relevant scheme of the first connecting member 34a. At the same time, the second connecting member 35a and the first connecting member 34a are allowed to be slightly different in the detailed structure or position arrangement of the components. The details will not be repeated here.

[0236] Fig.17 yes Figure 1 The keyboard 100 shown in FIG. Figure 1 . Fig.18 yes Fig.17 The shown schematic diagram is a partial cross-section of a keyboard 100 according to an embodiment of the present invention, taken along line BB.

[0237] like Fig.17 and Fig.18 As shown, 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. Fig.14A As shown, 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 through the first fixing seat 32 and the second fixing seat 33 (see Fig.14A In other embodiments, when the first button 3a does not include the first fixing seat 32 and the second fixing seat 33, or 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 Fig.14A ).

[0238] Exemplarily, the first rotating portion 345a of the first rotating end 341a of the first connecting member 34a may be located in 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 may rotate in the first rotating shaft groove 325 of the first fixing seat 32. In other embodiments, the structural form of the first rotating portion 345a of the first connecting member 34a and the structural form of the first rotating shaft groove 325 of the first fixing seat 32 may be swapped, that is, the first rotating portion 345a of the first connecting member 34a may adopt a rotating shaft groove structure or a rotating shaft hole structure. The first fixing seat 32 may be provided with a rotating shaft protrusion structure.

[0239] Exemplarily, the second rotating portion 346a of the first rotating end 341a of the first connecting member 34a may be located in 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 may rotate in the third rotating shaft groove 335 of the second fixing seat 33. In other embodiments, the structural form of the second rotating portion 346a of the first connecting member 34a and the structural form of the third rotating shaft groove 335 of the second fixing seat 33 may be swapped, that is, the second rotating portion 346a of the first connecting member 34a may adopt a rotating shaft groove structure or a rotating shaft hole structure. The second fixing seat 33 may be provided with a rotating shaft protrusion structure.

[0240] like Fig.17 and Fig.18 As shown, the second connecting member 35a can be movably connected to the first fixing seat 32 and the second fixing seat 33. For example, the second rotating end 351a of the second connecting member 35a can be rotatably connected to the first fixing seat 32 and the second fixing seat 33. It can be understood that the second connecting member 35a can be rotatably connected to the circuit board 2 through the first fixing seat 32 and the second fixing seat 33 (see Fig.14A In other embodiments, when the first button 3a does not include the first fixing seat 32 and the second fixing seat 33, the second connecting member 35a may also be directly connected to the circuit board 2 (see Fig.14A ).

[0241] Exemplarily, the third rotating portion 355a of the second rotating end 351a of the second connecting member 35a may 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 may rotate in the second rotating shaft groove 326 of the first fixing seat 32.

[0242] Exemplarily, the fourth rotating portion 356a of the second rotating end 351a of the second connecting member 35a may 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 may rotate in the fourth rotating shaft groove 336 of the second fixing seat 33.

[0243] Fig.19 yes Fig.17 The partial cross-sectional schematic diagram of a partial keyboard 100 at line CC of an embodiment is shown.

[0244] See also Fig.19 , and combined with Fig.17 and Fig.18 As shown, the first gear portion 344a of the first rotating end 341a of the first connecting member 34a can be meshed with the second gear portion 354a of the second rotating end 351a of the second connecting member 35a.

[0245] In one embodiment, the first sub-gear portion 3443a of the first connecting member 34a may be meshed 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 is meshed with the first tooth 3545a of the first sub-gear portion 3543a of the second connecting member 35a. The second tooth 3446a of the first sub-gear portion 3443a of the first connecting member 34a (see Fig.16 ) is meshed with the second tooth 3546a of the first sub-gear portion 3543a of the second connecting member 35a. In addition, the first tooth 3445a of the first connecting member 34a is meshed with the second tooth 3446a (see Fig.16 ) 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 tooth 3445a and the second tooth 3446a of the first sub-gear portion 3443a of the first connecting member 34a (see Fig.16 ) can be staggeredly meshed with the first teeth 3545a and the second teeth 3546a of the first sub-gear portion 3543a of the second connecting member 35a. In this way, 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 limited 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 being disengaged from the X-axis direction.

[0246] See also Fig.19 , and combined with Fig.17 and Fig.18As shown, the second sub-gear portion 3444a of the first connecting member 34a is also meshed with the second sub-gear portion 3544a of the second connecting member 35a. It can be understood that the meshing mode 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 refer to the meshing mode 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. The details are not repeated here.

[0247] It can be 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 meshed, so that the rotational motions of the first connecting member 34a and the second connecting member 35a can be kept synchronous, that is, they are synchronously approaching or moving away from each other. In addition, since 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 angle of the first connecting member 34a and the rotation angle of the second connecting member 35a can be the same.

[0248] It is understandable that, although the present embodiment introduces 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, size, etc. 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 may be designed according to the specific form, size, etc. of the product.

[0249] like Figures 17 to 19 As shown, when the first button 3a is in an unpressed state, the angle between the first connecting member 34a and the second connecting member 35a is a first angle. The first angle may be in the range of 120° to 160°. For example, the first angle may be 120°, 125°, 145°, 150° or 160°, etc. At this time, the first connecting member 34a and the second connecting member 35a are roughly in a "scissor" shape.

[0250] In addition, when the first key 3a is not pressed, the first avoidance hole 3421a of the first connecting member 34a is connected to the second avoidance hole 3521a of the second connecting member 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 key 3a or other components of the keyboard 100, thereby avoiding interference between other components of the first key 3a and other components of the keyboard 100 and the first connecting member 34a and the second connecting member 35a.

[0251] Combination Fig. 14B ,like Fig.17 and Fig.18 As shown, 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 may be located in the first stop slot 327 of the first fixing seat 32 and abut against the bottom wall of the first stop slot 327. The bottom wall of the first stop slot 327 may be used to limit the first connecting member 34a from continuing to rotate relative to the first fixing seat 32 when the first button 3a is in the unpressed state. In addition, at least a portion of the second stop portion 357a of the second rotating end 351a of the second connecting member 35a may also be located in the second stop slot 337 of the second fixing seat 33 and abut against the bottom wall of the second stop slot 337. The bottom wall of the second stop slot 337 may be used to limit the second connecting member 35a from continuing to rotate relative to the second fixing seat 33 when the first button 3a is in the unpressed state.

[0252] Fig. 20 yes Fig.17 The structure diagram of the partial keyboard 100 shown is in a triggered state. Fig.21 yes Fig. 20 The cross-sectional view of a portion of the keyboard 100 taken along line DD is shown in one embodiment.

[0253] like Fig. 20 and Fig.21 As shown, when the first button 3a is in the trigger state, the angle between the first connecting member 34a and the second connecting member 35a is the second angle. The second angle is greater than the first angle. Exemplarily, the second angle can be in the range of 160° to 180°. For example, the second angle can be 160°, 170° or 180°, etc. At this time, when the second angle is 180°, the first connecting member 34a and the second connecting member 35a can be in the shape of a "one".

[0254] In addition, when the first button 3 a is in the trigger state, the first stop portion 347 a can be separately disposed from the bottom wall of the first stop groove 327 , and the second stop portion 357 a can be separately disposed from the bottom wall of the second stop groove 337 .

[0255] Fig. 22 yes Figure 1 The keyboard 100 shown in FIG. Figure 2 .

[0256] like Fig. 22 As shown, 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.

[0257] For example, the first elastic member 36a may be a spring. The first end 361a of the first elastic member 36a (see Fig.15 ) can pass through the first mounting hole 3423a of the first connecting member 34a and be hooked on 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 ) can pass through the second mounting hole 3523a of the second connecting member 35a and be hooked on the second connecting shaft 3522a of the second connecting member 35a (see Fig.16 ). The connection method of the first elastic member 36a with the first connecting member 34a and the second connecting member 35a in this embodiment is relatively simple. In other embodiments, when the first elastic member 36a adopts other forms of structure, the connection method of the first elastic member 36a with the first connecting member 34a and the second connecting member 35a is not specifically limited. In other embodiments, the first button 3a may not adopt the first elastic member 36a, but drive the first connecting member 34a and the second connecting member 35a to move through other driving mechanisms.

[0258] like Fig. 22 As shown, when the first button 3a is in an unpressed state, at least a portion of the first elastic member 36a may be located in a space surrounded by the first avoidance hole 3421a of the first connecting member 34a and the second avoidance hole 3521a of the second connecting member 35a.

[0259] Fig.23 yes Fig.15 The structure diagram of the first key cap 31a shown is shown at another angle.

[0260] like Fig.23 As shown, the first key cap 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 disposed in opposite directions. The top surface 313a of the first pressing plate 311a is 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 surround a first receiving groove 315a.

[0261] Exemplarily, the first keycap 31a further includes a first guide block 3161a, a second guide block 3162a, a third guide block 3163a and a fourth guide block 3164a. The first guide block 3161a, the second guide block 3162a, the third guide block 3163a and the fourth guide 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.

[0262] In addition, the first guide block 3161a, the second guide block 3162a, the third guide block 3163a and the fourth guide block 3164a are all provided with guide grooves 3165a. The guide grooves 3165a of the first guide block 3161a are arranged opposite to the guide grooves 3165a of the second guide block 3162a. The guide grooves 3165a of the third guide block 3163a are arranged opposite to the guide grooves 3165a of the fourth guide block 3164a.

[0263] Exemplarily, 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.

[0264] like Fig.23 As shown, the first keycap 31a also includes a first stopper 3171a and a second stopper 3172a. The shapes of the first stopper 3171a and the second stopper 3172a can be a cuboid, a cylinder or other shapes. This embodiment is described by taking the shape of the first stopper 3171a and the second stopper 3172a as an example. Among them, the first stopper 3171a and the second stopper 3172a are both convexly arranged on the bottom surface 314a of the first pressing plate 311a, and are both located in the first receiving groove 315a. The first stopper 3171a is located on the same side of the first guide block 3161a and the second guide block 3162a, and the first stopper 3171a is directly opposite to the space between the first guide block 3161a and the second guide block 3162a. The second stopper 3172a is located on the same side of the third guide block 3163a and the fourth guide block 3164a, and the second stopper 3172a is directly opposite to the space between the third guide block 3163a and the fourth guide block 3164a.

[0265] like Fig.23As shown, 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, Fig.23 Only some avoidance grooves 318a are schematically provided. The number, shape, size and position of the avoidance grooves 318a are not specifically limited in this application, and can be designed according to the specific form and size of the product, for example.

[0266] Fig.24 yes Figure 2 The diagram shown is a partial structural diagram of a first button 3a in one embodiment. Fig.25 yes Fig.24 The shown diagram is a partial cross-sectional view of a first key 3a in one embodiment at line EE.

[0267] like Fig.24 and Fig.25 As shown, the first movable end 343a of the first connecting member 34a is movably connected to the first key cap 31a. Exemplarily, the first movable end 343a of the first connecting member 34a is slidably connected to the first key cap 31a and can rotate relative to each other.

[0268] Exemplarily, the first body portion 348a of the first movable end 343a of the first connecting member 34a is located 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 located in the guide groove 3165a of the first guide rail block 3161a of the first keycap 31a, and can slide and rotate in 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 located in the guide groove 3165a of the second guide rail block 3162a of the first keycap 31a, and can slide and rotate in the guide groove 3165a of the second guide rail block 3162a.

[0269] like Fig.25 As shown, the second movable end 353a of the second connecting member 35a is movably connected to the first key cap 31a. Exemplarily, the second movable end 353a of the second connecting member 35a is slidably connected to the first key cap 31a and can rotate relative to each other.

[0270] Exemplarily, the second body portion 358a of the second movable end 353a of the second connecting member 35a is located between the third guide rail block 3163a and the fourth guide rail block 3164a of the first key cap 31a. The third movable portion 3591a of the second movable end 353a of the second connecting member 35a is located in the guide groove 3165a of the third guide rail block 3163a of the first key cap 31a, and can slide and rotate in 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 located in the guide groove 3165a of the fourth guide rail block 3164a of the first key cap 31a, and can slide and rotate in the guide groove 3165a of the fourth guide rail block 3164a.

[0271] like Fig.25 As shown, 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 can be understood that, by the mutual cooperation of the wall surface of the guide groove 3165a of the first guide rail block 3161a and the wall surface of the guide groove 3165a of the second guide rail block 3162a, the first connecting member 34a can be restricted from continuing to slide and rotate relative to the first key cap 31a when the first key 3a is in a non-pressed state. In addition, by the mutual cooperation of the wall surface of the guide groove 3165a of the third guide rail block 3163a and the wall surface of the guide groove 3165a of the fourth guide rail block 3164a, the second connecting member 35a can be restricted from continuing to slide and rotate relative to the first key cap 31a when the first key 3a is in a non-pressed state.

[0272] Fig.26 yes Fig.24 The structure diagram of part of the first button 3a shown is in the triggered state. Fig. 27 yes Fig.26 The cross-sectional view of a portion of the first key 3a at line FF is shown in one embodiment.

[0273] like Fig.26 and Fig. 27 As shown, when the first button 3a is in the trigger 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 separated in the positive direction of the Y axis, and the second movable portion 3492a of the first connecting member 34a and the guide groove 3165a of the second guide rail block 3162a (see Fig.25 ) 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.

[0274] like Fig.26 and Fig. 27 As shown, when the first button 3a is in the trigger 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 can be understood that the first stopper 3171a can be used to stop the first connecting member 34a when the first button 3a is in the trigger state, so as to prevent the first movable end 343a of the first connecting member 34a from moving out of the guide groove 3165a of the first guide block 3161a and the second guide block 3162a. The second stopper 3172a can be used to stop the second connecting member 35a when the first button 3a is in the trigger state, so as to prevent the second movable end 353a of the second connecting member 35a from moving out of the guide groove 3165a of the third guide block 3163a and the fourth guide block 3164a.

[0275] Fig.28 yes Figure 1 A partial cross-sectional view of one embodiment of a portion of keyboard 100 is shown at line GG.

[0276] like Fig.28 As shown, when the first key 3a is in an unpressed state, the first connecting member 34a and the second connecting member 35a support the first key cap 31a. In the Z-axis direction, the distance between the first key cap 31a and the trigger end 21 of the circuit board 2 is a first distance D1.

[0277] Exemplarily, when the first button 3a is in an unpressed state, the first elastic member 36a (see Fig. 22 ) can be in a stretched state. In this way, 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. At this time, when the user accidentally touches the first keycap 31a, the first keycap 31a will not immediately move along the negative direction of the Z axis, and the first keycap 31a will not squeeze the trigger end 21 of the circuit board 2 to cause the circuit board 2 to generate an electrical signal.

[0278] Fig.29 yes Fig.28 A partial cross-sectional view of an embodiment of a portion of the keyboard 100 is shown in a triggered state.

[0279] like Fig.29 As shown, when the first key 3a is in the trigger state, in the Z-axis direction, the distance between the first key cap 31a and the trigger end 21 of the circuit board 2 is the second distance D2. The second distance D2 is smaller than the first distance D1 (see Fig.28 ). At this time, the distance between the first key cap 31a and the trigger end of the circuit board is relatively short.

[0280] like Fig.28 and Fig.29 As shown, when the first key 3a switches from the unpressed state to the triggered state, the first key cap 31a is pressed so that the first key cap 31a can move along the negative direction of the Z axis, and the first key cap 31a squeezes the first connecting member 34a and the second connecting member 35a, and the first rotating end 341a of the first connecting member 34a and the second rotating end 351a of the second connecting member 35a can both rotate relative to the first fixed seat 32 and the second fixed seat 33. In addition, the first movable end 343a of the first connecting member 34a can slide relative to the first key cap 31a, and there is relative rotation, and the second movable end 353a of the second connecting member 35a can slide relative to the first key cap 31a, and there is relative rotation. 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 are separated from each other, and the first connecting member 34a and the second connecting member 35a are opened, that is, the angle between the first connecting member 34a and the second connecting member 35a increases. In addition, the first elastic member 36a is elongated and is in a stretched state. It is understandable that when the first key cap 31a moves along the negative direction of the Z axis, the distance between the first key cap 31a and the trigger end 21 of the circuit board 2 decreases. In this way, the first key cap 31a can indirectly or directly press the trigger end 21 of the circuit board 2 to make the circuit board 2 generate an electrical signal.

[0281] It is understandable that when the first key 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. At this time, in the process of pressing the first keycap 31a to move along the negative direction of the Z axis, the force applied by the first elastic member 36a to the first keycap 31a needs to be overcome first, which is conducive to improving the user's hand feeling in the process of pressing the first keycap 31a.

[0282] In one embodiment, the keyboard 100 includes a trigger member 5, and the trigger member 5 is an elastic member. The trigger member 5 is fixed to the trigger end 21 of the circuit board 2 as an example for description. In this way, when the first key cap 31a moves to contact the trigger member 5, the first key cap 31a can squeeze the trigger member 5. The trigger member 5 can be deformed and in a compressed state. The trigger member 5 can use its own elastic force to squeeze the trigger end 21 of the circuit board 2, so that the circuit board 2 generates an electrical signal.

[0283] In one embodiment, the keyboard 100 does not include the trigger member 5. At this time, as the distance between the first key cap 31a and the trigger end 21 of the circuit board 2 decreases, the first key cap 31a can directly contact the trigger end 21 of the circuit board 2 and press the trigger end 21 of the circuit board 2, so that the circuit board 2 generates an electrical signal.

[0284] It can be understood that, since 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, when the second gear portion 354a of the second connecting member 35a is meshed 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 trigger 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 small. Exemplarily, A1 can satisfy: 0°≤A1<3°.

[0285] like Fig.28 and Fig.29 As shown, when the first key 3a switches from the trigger state to the unpressed state, a force is applied to the first connecting member 34a and the second connecting member 35a, so that the first rotating end 341a of the first connecting member 34a and the second rotating end 351a of the second connecting member 35a can rotate relative to the first fixed seat 32 and the second fixed seat 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 slide relative to the first keycap 31a, and there is relative rotation. 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 are close to each other, and the first connecting member 34a and the second connecting member 35a are close to each other, that is, the angle between the first connecting member 34a and the second connecting member 35a is reduced. The first connecting member 34a and the second connecting member 35a can squeeze the first keycap 31a, so that the first keycap 31a can move along the positive direction of the Z axis. It is understandable that when the first key cap 31a moves along the positive direction of the Z axis, the distance between the first key cap 31a and the trigger end 21 of the circuit board 2 increases. In this way, the first key cap 31a no longer directly or indirectly presses the trigger end 21 of the circuit board 2, and the circuit board 2 does not generate an electrical signal.

[0286] 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 specifically described below in conjunction with the relevant drawings.

[0287] Fig.30 yes Figure 1 The keyboard 100 shown is a partially exploded schematic diagram in another embodiment.

[0288] like Fig.30 As shown, the first elastic member 36a has a first center line La. The first center line La passes through the center of the first elastic member 36a and is parallel to the length extension direction of the first elastic member 36a. It can be understood that when the first elastic member 36a is a spring, the first center line La of the first elastic member 36a can be the central axis of the spring.

[0289] When the first button 3a is in the trigger state, the first center line La of the first elastic member 36a is set at an angle with 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.

[0290] It can be understood that, since 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 elastic force applied by the first elastic member 36a to the first connecting member 34a and the second connecting member 35a can generate a component force in the positive direction of the Z axis. At this time, the component force can make the first rotating end 341a of the first connecting member 34a 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 can rotate clockwise relative to the first fixing seat 32 and the second fixing seat 33, so that the first button 3a can switch from the triggered state to the unpressed state.

[0291] 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 also 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.

[0292] Fig.31 yes Fig.28 A partial cross-sectional view of another embodiment of a partial keyboard 100 is shown in a triggered state.

[0293] like Fig.31As shown, the center of rotation of the first connecting member 34a relative to the first fixed seat 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. Among them, 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. Among them, the bottom surface 23 of the circuit board 2 is the surface of the circuit board 2 facing away from the first keycap 31a.

[0294] When the first key 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. Combined with Fig.19 As shown, 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 key 3a can be switched from the triggered state to the unpressed state.

[0295] Similarly, the distance between the center O3 of rotation of the second connecting member 35a 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 rotation of the second connecting member 35a relative to the first keycap 31a and the bottom surface 23 of the circuit board 2 is the fourth height H4. When the first key 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 key 3a to be switched from the triggered state to the unpressed state.

[0296] In other embodiments, when the first key 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 key 3a switch from the triggered state to the unpressed state.

[0297] As Fig.28 and Fig.29As shown, the keyboard 100 includes a trigger member 5, and the trigger member 5 is an elastic member. The trigger member 5 is fixed on the trigger end 21 of the circuit board 2 as an example for description. When the first key 3a is in the trigger 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, so that the circuit board 2 generates an electrical signal.

[0298] When the first key 3a switches from the trigger state to the unpressed state, since the first key cap 31a is no longer subjected to the pressing force, the elastic force applied by the trigger member 5 to the first key cap 31a can make the first key cap 31a move along the positive direction of the Z axis. At this time, the first key cap 31a can apply a force to the first connecting member 34a and the second connecting member 35a, so that the first rotating end 341a of the first connecting member 34a can 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 can rotate clockwise relative to the first fixing seat 32 and the second fixing seat 33. In this way, the first key 3a can switch from the trigger state to the unpressed state.

[0299] The structure of the first key 3a is described in detail above with reference to the relevant drawings. An assembly method of the first key 3a is described below with reference to the relevant drawings.

[0300] Combination Fig. 22 As shown, 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.

[0301] Combination Fig.19 As shown, 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.

[0302] Combination Fig.18 As shown, 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.

[0303] Combination Fig.14A and Fig. 14BAs shown, the first fixing seat 32 and the second fixing seat 33 are fixed on the circuit board 2 and respectively trigger the two sides of the end 21 .

[0304] Combination Figure 23 to Figure 25 As shown, 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 key cap 31a.

[0305] It is understandable that when the keyboard 100 includes the trigger member 5 , the trigger member 5 can be installed on the first key cap 31 a in advance, or installed on the trigger end 21 , etc.

[0306] The above text describes in detail several implementations of the first button 3a switching from the triggered state to the unpressed state in conjunction with the relevant drawings. The following text describes in detail other structures of the first connecting member 34a and the second connecting member 35a in conjunction with the relevant drawings.

[0307] Fig.32 yes Fig.15 The structure diagram of the first connecting member 34a and the second connecting member 35a in another embodiment is shown.

[0308] like Fig.32 As shown, the first connecting member 34a is provided with a first avoidance hole 3421a. 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 which are arranged at intervals.

[0309] Exemplarily, the first sub-gear portion 3443a of the first connecting member 34a includes a first tooth 3445a. The second sub-gear portion 3444a of the first connecting member 34a includes a second tooth 3446a and a third tooth 3447a which are spaced apart and arranged opposite to each other.

[0310] like Fig.32 As shown, the second connecting member 35a is provided with a second avoidance hole 3521a. 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 which are arranged at intervals.

[0311] 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 arranged opposite to each other. The second sub-gear portion 3544a of the second connecting member 35a includes a third tooth 3547a.

[0312] Fig.33 yes Fig.32 FIG. 1 is a schematic diagram of assembling the first connecting member 34 a and the second connecting member 35 a.

[0313] like Fig.32 and Fig.33 As shown, the first sub-gear portion 3443a of the first connecting member 34a may mesh with the first sub-gear portion 3543a of the second connecting member 35a. The first tooth 3445a of the first connecting member 34a may be located between the first tooth 3545a and the second tooth 3546a of the second connecting member 35a.

[0314] like Fig.32 and Fig.33 As shown, the second sub-gear portion 3444a of the first connecting member 34a may mesh with the second sub-gear portion 3544a of the second connecting member 35a, wherein the third tooth 3547a of the second connecting member 35a may be located between the second tooth 3446a and the third tooth 3447a of the first connecting member 34a.

[0315] 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.

[0316] It is understandable that compared to Fig.16 and Fig.17 The first gear portion 344a of the first connecting member 34a and the second gear portion 354a of the second connecting member 35a are arranged in an alternating tooth structure. In this embodiment, the first gear portion 344a of the first connecting member 34a and the second gear portion 354a of the second connecting member 35a are longer in the X-axis direction, so that the first gear portion 344a of the first connecting member 34a and the second gear portion 354a of the second connecting member 35a have better structural strength and are not easily damaged.

[0317] It is understandable that compared to Fig.32 and Fig.33 The toothed 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 is shown. Fig.16 and Fig.17 The staggered tooth structures of the first gear portion 344a of the first connecting member 34a and the second gear portion 354a of the second connecting member 35a have a smaller thickness in the Z-axis direction, which is conducive to the thinning of the first key 3a.

[0318] The structure of the first button 3a is described in detail above in conjunction with the relevant drawings. The structure of the second button 3b will be described in detail below in conjunction with the relevant drawings. It can be understood that most of the structures of the second button 3b of 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 outside the 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 is the same as the first button 3a in the second button 3b will not be repeated here. The following will focus on the differences between the second button 3b and the first button 3a.

[0319] Fig.34 yes Figure 2 The second button 3 b is shown in a partially exploded view in one embodiment. Fig.35 yes Figure 1 The keyboard 100 is shown as a partial cross-sectional schematic diagram of an embodiment at line HH. Fig.36 yes Fig.35 The illustrated embodiment is a partial cross-sectional view of an embodiment in which the second key 3 b of the keyboard 100 is in a triggered state.

[0320] like Figure 34 to Figure 36 As shown, 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 design of the component structure of the second keycap 31b, the third connecting member 34b, the fourth connecting member 35b and the second elastic member 36b, the connection relationship design between the components, and other connection relationship designs outside the components and assemblies can all refer to the related schemes of 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, 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, the second rotating end 351b of the fourth connecting member 35b includes a second gear portion 354b, and the first gear portion 344b of the third connecting member 34b is meshed with the second gear portion 354b of the fourth connecting member 35b. It can be 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 Figure 34 to Figure 36 The structure shown can also be Fig.16 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 can be arranged in a staggered meshing manner.

[0321] In this embodiment, the diameter of the pitch circle of the first gear portion 344b of the third connecting member 34b of the second key 3b is not equal to the diameter of the pitch circle of the second gear portion 354a of the fourth connecting member 35b, that is, 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 is not equal to 1. In this way, when the first gear portion 344b of the third connecting member 34b is meshed 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 are different in size. At this time, the movement speed of the part of the second keycap 31b connected to the third connecting member 34b is different from the movement speed of the part of the second keycap 31b connected to the fourth connecting member 35b. When the second key 3b is in the trigger 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 may satisfy: A2 ≥ 3°. Figures 15 to 33 In the foregoing, the diameter of the pitch circle of the first gear portion 344a of the first connecting member 34a of the first button 3a is equal to the diameter of the pitch circle of the second gear portion 354a of the second connecting member 35a of the first button 3a, that is, the ratio of the diameter of the pitch circle of the first gear portion 344a of the first connecting member 34a of the first button 3a to the diameter of the pitch circle of the second gear portion 354a of the second connecting member 35a of the first button 3a is 1. In this way, when the first gear portion 344a of the first connecting member 34a is meshed with the second gear portion 354a of the second connecting member 35a, the rotation angle of the first connecting member 34a and the rotation angle of the second connecting member 35a can be the same. At this time, whether the first button 3a is in an unpressed state or in a triggered state, the angle between the first central axis L1 of the first button 3a and the circuit board 2 is substantially unchanged. At this time, when the first button 3a is in a 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 small. Therefore, when both the first button 3a and the second button 3b are in the trigger 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 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, and 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 greater. Exemplarily, b satisfies: b≥3°.

[0322] Exemplarily, the diameter of the pitch circle of the first gear portion 344b of the third connecting member 34b is smaller than the diameter of the pitch circle of the second gear portion 354a of the fourth connecting member 35b, that is, 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 is smaller than 1. In this way, when the first gear portion 344b of the third connecting member 34b is meshed 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. Among them, compared with the second gear portion 354b of the fourth connecting member 35b, the first gear portion 344b of the third connecting member 34b is closer to the first key 3a. At this time, when the first key 3a and the second key 3b are both in the trigger state, the second keycap 31b of the second key 3b is tilted in the direction close to the first key 3a. It is understandable that by setting 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 large, the inclination of the second keycap 31b of the second key 3b is greater.

[0323] It can be understood that the diameter of the pitch circle of the first gear part 344a of the first connecting member 34a of the first button 3a is the first diameter. The diameter of the pitch circle of the second gear part 354a of the second connecting member 35a of the first button 3a is the second diameter. Wherein, when the first diameter is not equal to the second diameter, the ratio of the maximum value to the minimum value of the first diameter and the second diameter is the first value. For example, the first diameter is 2 mm and the second diameter is 5 mm. In this way, the first diameter is the minimum value and the second diameter is the maximum value. At this time, the first value is the ratio of 5 to 2, that is, 2.5. When the first diameter is equal to the second diameter, the ratio of the first diameter to the second diameter is the first value. This embodiment is described by taking the first diameter and the second diameter as an example of being equal (that is, the first value is equal to 1). In addition, the diameter of the pitch circle of the first gear part 344b of the third connecting member 34b of the second button 3b is the third diameter. The diameter of the pitch circle of the second gear part 354a of the fourth connecting member 35b is the fourth diameter. The third diameter is not equal to the fourth diameter, and the ratio of the maximum value to the minimum value of the third diameter and the fourth diameter is the second value. For example, the third diameter is 2 mm, and the fourth diameter is 6 mm. In this way, the third diameter is the minimum value. The fourth diameter is the maximum value. At this time, the second value is the ratio of 6 to 2, that is, 3. In this embodiment, the second value is greater than the first value.

[0324] 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 trigger 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, and the inclination angle of the second keycap 31b of the second button 3b is larger than that of the first keycap 31a of the first button 3a. In this way, 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 larger, thereby achieving different orientations of the top surface 30a of the first button 3a and the top surface 30b of the second button 3b. At this time, when both the first button 3a and the second button 3b are in the trigger state, the setting mode of the first button 3a and the second button 3b can meet the ergonomic theory, and the user experience is better. It can be understood that when the difference between the second value and the first value is larger, the inclination angle of the second keycap 31b of the second button 3b is larger than that of 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 key 3a and the second central axis L2 of the second key 3b is larger. When the difference between the second value and the first value is smaller, the inclination angle of the first keycap 31a of the first key 3a and the inclination angle of the second keycap 31b of the second key 3b are closer. In this way, the included angle b between the first central axis L1 of the first key 3a and the second central axis L2 of the second key 3b is smaller.

[0325] 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 a triggered state, the top surface 30a of the first key 3a and the top surface 30c of the third key 3c are oriented differently.

[0326] like Fig.36 As shown, illustratively, the second movable end 353b of the fourth connecting member 35b further includes a stopper 3531b. The stopper 3531b is protruded from the bottom surface of the second body portion 358b of the second movable end 353b of the fourth connecting member 35b. The bottom surface of the second body portion 358b of the fourth connecting member 35b is the surface of the second body portion 358b of the fourth connecting member 35b away from the second keycap 31b.

[0327] It is understandable that when the second key 3b is in the trigger state, the limit block 3531b can be abutted against the reinforcement plate 4, thereby maintaining the shape of the second keycap 31b on the one hand, and preventing the second gear portion 354b of the fourth connection member 35b and the first gear portion 344b of the third connection member 34b from being broken due to over-bending of the fourth connection member 35b, thereby ensuring that the third connection member 34b and the fourth connection member 35b have better reliability. In other embodiments, when the reinforcement plate 4 is not provided on the circuit board 2, or the reinforcement plate 4 is not provided on the top surface 22 of the circuit board 2, the limit block 3531b can be directly abutted against the circuit board 2. This application does not make any specific limitations.

[0328] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of the present application. In other words, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0329] It should be noted that all the above drawings are illustrative illustrations of the present application and do not represent the actual size of the product. And the dimensional ratio relationship between the components in the drawings does not serve as a limitation on the actual product of the present application. The above are only some embodiments and implementation methods of the present application. The scope of protection of the present application is not limited to this. Any technician familiar with the field can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be based on the scope of protection of the claims.
