Description

Technical Field

[0001] The present application relates to the field of keyboard technology, and in particular to a keyboard, an electronic device, and a keyboard cover. Background Art

[0002] With the advancement of science and technology, electronic devices such as laptops are moving towards being thinner and lighter. As the main way to input information, the keyboard of a laptop is frequently used, and the experience of using the keyboard will affect the experience of using electronic devices such as laptops. Therefore, the thin and light design of the keyboard is conducive to improving the experience of using electronic devices such as laptops. Utility Model Content

[0003] The purpose of the embodiments of the present application is to provide a keyboard, an electronic device and a keyboard cover. The keyboard of the embodiments of the present application can have a thinner size and a lighter weight, and a good user experience.

[0004] In a first aspect, an embodiment of the present application provides a keyboard, which includes a base plate and a plurality of keys, wherein the plurality of keys are fixed to one side of the base plate; the base plate has a plurality of key switches; the keys include keycaps, support members and elastic members, the keycaps are spaced apart and arranged relative to the base plate, the first end of the support member is fixedly connected to the keycaps, the second end of the support member is fixedly connected to the base plate, the elastic member is located on the inner side of the support member, the first end of the elastic member is fixedly connected to the keycaps, the second end of the elastic member is fixedly connected to the base plate, and both the support member and the elastic member are flexible members; the elastic member is arranged corresponding to the key switches, and the elastic member is used to trigger the key switches when the keycaps are pressed.

[0005] Exemplarily, one button may be provided with one button switch, or one button may be provided with multiple button switches.

[0006] Exemplarily, the elastic member can contact or press the key switch by deformation to trigger the key switch.

[0007] Among them, since the support member and the elastic member are both flexible members, when the user presses the key, the support member and the elastic member are deformed by force, so that the keycap moves toward the bottom plate. At this time, when the elastic member is deformed, part of its structure moves toward the bottom plate, and the elastic member can contact the key switch of the bottom plate, thereby triggering the key switch and realizing the triggering of the key; when the user releases the key, since the elastic member and the support member have elastic restoring force, the elastic member and the support member can be used to drive the keycap to reset, so that the keycap moves in the direction away from the bottom plate until it returns to the height when it is not pressed. It can be understood that the support member can also have elastic deformation ability.

[0008] In this embodiment, by providing a flexible support member and an elastic member, the support member and the elastic member can both have strong compression deformation capabilities, so that the structure between the key cap and the bottom plate can have sufficient deformation capabilities. When the support member and the elastic member have a relatively low height, the key can also have a sufficient key travel to achieve triggering, which is conducive to the thin design of the key. Since the support member has a simple structure, light weight and low cost, it is conducive to the overall thin design of the keyboard, has a relatively low cost, and has a good user experience.

[0009] In some embodiments, the elastic member includes an annular portion and a trigger portion, the annular portion having a first end and a second end, the first end of the annular portion is fixedly connected to the keycap, the second end of the annular portion is fixedly connected to the base plate, the trigger portion is located on the inner side of the annular portion and fixed to the first end of the annular portion, and the trigger portion is spaced apart from the corresponding key switch.

[0010] In this embodiment, the annular portion can be the main deformation structure of the elastic member after being stressed, and the side wall of the annular portion can be arranged at an angle to facilitate deformation after being stressed, thereby improving the user's pressing feel. The trigger portion is arranged at a distance from the corresponding key switch to prevent the trigger portion from triggering the key switch when the key is not pressed and causing an accidental touch.

[0011] In some embodiments, the hardness of the elastic member is greater than the hardness of the support member.

[0012] Among them, the support member is more likely to deform than the elastic member. When the keycap is under pressure, the elastic member will mainly provide an elastic reaction force acting on the keycap. The elastic force curve of the elastic member after being stressed will mainly affect the pressing feel of the key. After the key is pressed and the pressing force is lost, the support member applies elastic force to the keycap to restore the keycap to its initial position. When the key is not pressed, the support member can be the main supporting structure of the keycap.

[0013] In this embodiment, by setting the hardness of the elastic member and the support member, it is helpful to design the shape of the elastic member so that the elastic force curve of the elastic member after being pressed is more in line with the user's feel, which is helpful to improve the user's experience.

[0014] In some embodiments, the compression ratios of the support member and the elastic member are respectively greater than or equal to 2.

[0015] In this embodiment, both the support member and the elastic member have a strong deformation ability, so that the support member and the elastic member can have a large displacement in the height direction when they have a relatively low height, that is, the key can have a relatively large key travel. At this time, the height of the key can be as low as less than 1 mm, which greatly reduces the thickness and weight of the keyboard, and does not require a complex supporting structure to support the key, making the cost of the keyboard lower. Of course, the height of the key can also be higher than 1 mm. For example, the thickness of the key can be 3 mm, taking into account the user's feel. In this example, by setting the compression ratio of the support member and the elastic member, it is convenient to set the height of the key lower, which can further make the key thinner and lighter, thereby facilitating the thin and light design of the keyboard.

[0016] In some embodiments, the compression ratio of the support member is greater than the compression ratio of the elastic member.

[0017] In this embodiment, when the key is compressed, the compression degree of the support member is greater than that of the elastic member, so as to avoid the support member limiting the pressing degree of the key, thereby avoiding the support member having too great an impact on the pressing feel when the key is pressed.

[0018] In some embodiments, the support member is disposed around the elastic member.

[0019] In this embodiment, there may be a gap between the support member and the elastic member, and the support members are distributed around the elastic member, so that the keycap is equivalent to having a two-layer support structure, namely an inner elastic member and an outer support member, which has a better supporting capacity for the keycap.

[0020] In some embodiments, a through hole is formed in the side wall of the support member.

[0021] In this embodiment, by providing a through hole in the support member, the support member is more easily compressed when subjected to force, thereby improving the compressibility of the support member and reducing the supporting force of the support member on the keycap, thereby reducing the influence of the support member on the pressing feel of the user when pressing the key. In addition, the through hole can allow air to circulate inside and outside the support member, preventing pressure difference between the inside and outside of the support member when pressing the key, which is conducive to the deformation of the support member and improves the pressing feel of the user.

[0022] In some embodiments, the side wall of the support member is arranged in an arc shape, and the middle portion of the side wall of the support member protrudes in a direction away from the elastic member relative to both ends.

[0023] Among them, since the middle part of the side of the support member protrudes outward, when the keycap is subjected to force, the middle part of the side wall of the support member will deform first, and by making the middle part deform in the direction away from the elastic member, the overall deformation direction of the support member is made in the height direction of the keyboard.

[0024] In this embodiment, since the support member itself is bent, the support member does not need a large force to deform. When the key is pressed, the reaction force of the support member on the keycap is small, and the impact on the pressing feel is small. It is only necessary to design the elastic member to determine the pressing feel of the key, thereby simplifying the complexity of the key design. In addition, part of the structure of the support member is deformed in a direction away from the support member, which is conducive to making the support member have a larger compression ratio in the height direction of the keyboard, thereby facilitating the thin design of the key, that is, facilitating the thin design of the keyboard.

[0025] In some embodiments, the side wall of the support member includes a first wall panel and a second wall panel, one end of the first wall panel is fixedly connected to the keycap, and the other end is fixedly connected to the base plate, one end of the second wall panel is fixedly connected to the keycap, and the other end is fixedly connected to the base plate, and the first wall panel and the second wall panel are cross-arranged.

[0026] In this embodiment, since the first wall panel and the second wall panel of the support member cross each other, the side wall of the support member has a wider width, and the force exerted by the key on the support member is easy to overlap with the support member, so that the support member has better anti-deflection ability, that is, the support member has better deformation ability in the height direction of the keyboard, and is not easy to deflect or move in the height direction perpendicular to the keyboard, thereby improving the pressing feel and enhancing the user experience.

[0027] In some embodiments, the side wall of the support member includes a third wall panel and a fourth wall panel, one end of the third wall panel is fixedly connected to the keycap, and the other end is fixedly connected to the base plate, one end of the fourth wall panel is connected to the third wall panel, and the other end is fixedly connected to the base plate, and the fourth wall panel is located on a side of the third wall panel close to the elastic member.

[0028] In this embodiment, since the support member is connected to the bottom plate through the third wall plate and the fourth wall plate, the connection width between the support member and the bottom plate is relatively wide, and the support member is not easy to deflect when deformed; since the support member is connected to the key cap through the third wall plate, the support member is easy to deform. The support member of this embodiment has both moderate anti-deflection ability and easy pressing ability, and has a good user experience.

[0029] In some embodiments, the keycap has a stiffness greater than the stiffness of the support member.

[0030] When the key is subjected to force, the deformation of the keycap is smaller than that of the support member. In some examples, the keycap can be a rigid structure, and when the keycap is subjected to force, the pressing force can be applied to the support member and the elastic member simultaneously, thereby pressing the support member and the elastic member simultaneously.

[0031] In this embodiment, the force of the keycap on the support member and the elastic member, as well as the force on different parts of the support member are basically consistent, which can make the deformation of the support member and the elastic member more consistent, which is beneficial to moving the keycap in a direction perpendicular to the base plate, thereby preventing the keycap from deflecting when pressed, and also beneficial to improving the user's feel.

[0032] In some implementations, the keycap is made of hard plastic or fiberglass; the support member and / or the elastic member is made of rubber, silicone rubber or a flexible polymer material.

[0033] In this embodiment, the key cap is easily formed into a structure with high strength by setting the material of the key cap, and the support member and the elastic member are easily formed into a structure that is easily deformed by setting the materials of the support member and the elastic member.

[0034] In some embodiments, the keycap and the support member are integrally formed structural members.

[0035] In this embodiment, the support member and the key cap can be reliably fixedly connected, and the service life of the key is extended.

[0036] In a second aspect, an embodiment of the present application provides an electronic device, the electronic device comprising a keyboard provided in any embodiment of the first aspect.

[0037] In this embodiment, the electronic device with the keyboard can achieve a lightweight and thin design and provide a good user experience.

[0038] Exemplarily, the electronic device includes a housing device, a display screen, and a keyboard as provided in any embodiment of the first aspect, wherein the keyboard and the display screen are both mounted on the housing device, and both the keyboard and the display screen are exposed relative to the housing device.

[0064] The housing device 100 may include a top shell 1001 and a bottom shell 1002. The top shell 1001 and the bottom shell 1002 are rotatably connected, so that the top shell 1001 can rotate relative to the bottom shell 1002, so that the top shell 1001 can be opened and closed relative to the bottom shell 1002. The shapes of the top shell 1001 and the bottom shell 1002 can be substantially the same, so that the top shell 1001 and the bottom shell 1002 are more tightly fastened when they are fastened.

[0065] For example, the top shell 1001 and the bottom shell 1002 may be rotatably connected via a rotating shaft, or the top shell 1001 and the bottom shell 1002 may be rotatably connected via a hinge. For example, the maximum angle of the top shell 1001 relative to the bottom shell 1002 may be in the range of 90° to 360°, such as 150°, 180°, 270° or 360°, etc., which is not strictly limited in this embodiment.

When the first connection portion 1003 and the second connection portion 3001 are separated, the display screen 300 and the host 500 may be used as two devices, and the display screen 300 and the host 500 may be placed in different places for use according to the usage scenario.

[0085] Exemplarily, the display screen 300 can be connected to the host 500 for communication.

The plurality of keys 20 may be arranged at intervals from each other, so that the plurality of keys 20 are arranged independently from each other, so as to facilitate the operation of different keys 20. In some other embodiments, a plurality of key switches may also be arranged corresponding to one key 20.

[0097] The shape of the key 20 may be roughly rectangular, and in some other embodiments, the shape of the key 20 may also be circular. The sizes of different keys 20 may be different. The number of keys 20 may be greater than 60, for example, 61, 86, 101, 104, etc. The shape, size and number of the keys 20 may be adaptively set according to the requirements, and are not strictly limited in this embodiment.

[0098] The frame 30 may be fixedly connected to the bottom plate 10. For example, the frame 30 may be a substantially plate-shaped member, the frame 30 may be located on the same side of the bottom plate 10 as the plurality of keys 20, the frame 30 may be provided with a plurality of avoidance holes, the keys 20 may be located in the avoidance holes, and the avoidance holes are used to provide a movable space for the keys 20. The number of avoidance holes may be the same as the number of keys 20, and the plurality of avoidance holes may be arranged in a one-to-one correspondence with the plurality of keys 20. In some other examples, the frame 30 may be a cover structure, and the bottom plate 10 may be arranged inside the frame 30 to protect the bottom plate 10.

[0099] In some other embodiments, the keyboard 200 may not include the frame 30, or the frame 30 may be formed by a housing structure of the electronic device.

[0100] Please refer to Figures 6 to 8 , Figure 6 yes Figure 5 The schematic cross-sectional view of the keyboard 200 is a partial structure cut along AA. Figure 7 yes Figure 6 The exploded schematic diagram of the partial structure of the keyboard 200 is shown, Figure 8 yes Figure 6 The structure diagram of the keyboard 200 in some embodiments is shown. Figure 8 The key 20 in is in a pressed state.

[0101] In some embodiments, the bottom plate 10 may include a support plate 101, a thin film circuit board 102, and a backlight plate 103. The thin film circuit board 102 and the backlight plate 103 are respectively arranged on both sides of the support plate 101, and the button 20 may be arranged on the side of the thin film circuit board 102 away from the support plate 101.

[0102] The support plate 101 may be, but is not limited to, a hard metal plate such as a steel plate, so as to support the thin film circuit board 102 , the backlight plate 103 and the button 20 .

[0103] A switch circuit may be provided on the film circuit board 102, and the switch circuit has a key switch 1021. When the key 20 is pressed, the key switch 1021 of the film circuit board 102 may be changed from an open state to a closed state to trigger the pressed key 20, thereby realizing the input function corresponding to the key 20.

[0104] The backlight plate 103 may have a light emitting element to emit light. The light emitted by the backlight plate 103 may pass through the support plate 101 and the thin film circuit board 102 in sequence, thereby realizing the luminous effect of the keyboard 200, so that the user can clearly see the letters and symbols on the keys 20 even when the light environment is poor.

[0105] In some other examples, the bottom plate 10 may not have the backlight plate 103. In this case, the keyboard 200 may not have the lighting function, or each key 20 of the keyboard 200 may have an independent lighting function, which may be set according to actual needs and is not strictly limited in this embodiment.

[0106] In some embodiments, the key 20 may include a key cap 1, a support member 2 and an elastic member 3. The key cap 1 and the base plate 10 are spaced apart and arranged opposite to each other, and the support member 2 and the elastic member 3 are located between the key cap 1 and the base plate 10.

[0107] The support member 2 may have a first end 21 and a second end 22. The first end 21 of the support member 2 is fixedly connected to the keycap 1, and the second end 22 of the support member 2 is fixedly connected to the base plate 10. The elastic member 3 is arranged corresponding to the key switch 1021, and the elastic member 3 is used to trigger the key switch 1021 when the keycap 1 is pressed. The elastic member 3 may be located on the inner side of the support member 2. The elastic member 3 may have a first end 33 and a second end 34, and the first end 33 of the elastic member 3 is fixedly connected to the keycap 1, and the second end 34 of the elastic member 3 is fixedly connected to the base plate 10. The support member 2 and the elastic member 3 may both be flexible members. The elastic member 3 is used to trigger the key switch 1021 when the keycap 1 is pressed; that is, the elastic member 3 can be deformed to contact or press the key switch 1021 to trigger the key switch 1021, so that the key switch 1021 of the thin film circuit board 102 is changed from an open circuit state to a pass state.

[0108] Exemplarily, one button 20 may have one elastic member 3 , and a plurality of elastic members 3 may correspond one-to-one to a plurality of button switches 1021 .

[0109] In some other examples, a plurality of key switches 1021 may be provided corresponding to one elastic member 3 of a key 20, and the plurality of key switches 1021 may be used to trigger the key 20. Alternatively, a key 20 may have a plurality of elastic members 3, and each of the plurality of elastic members 3 may be provided with a key switch 1021, so that a key 20 is equivalent to being provided with a plurality of key switches 1021, and the plurality of key switches 1021 may be used to trigger the key 20. At this time, when the key 20 is longer, the key 20 can be more easily triggered.

[0110] The elastic member 3 may be located inside the support member 2. The elastic member 3 may be fixedly connected to the middle of the keycap 1, and the support member 2 may be fixedly connected to the edge of the keycap 1. At this time, the keycap 1 may be connected to the base plate 10 through the support member 2 and the elastic member 3, and each part of the keycap 1 has a supporting structure, so that the keycap 1 can be reliably fixed in the keyboard 200, with little shaking and good stability.

[0111] Exemplarily, the elastic member 3, the key cap 1 and the base plate 10 may be fixedly connected by bonding.

[0112] Exemplarily, the support member 2 and the keycap 1 and the base plate 10 can be fixedly connected by bonding. For example, the first end 21 of the support member 2 is bonded to the keycap 1, and the second end 22 of the support member 2 is bonded to the base plate 10. In other examples, the support member 2 can be formed with the keycap 1 by integral molding. In this case, the first end 21 of the support member 2 is fixedly connected to the keycap 1, so that the support member 2 and the keycap 1 can be reliably fixedly connected, and the service life of the key 20 is longer.

[0113] Among them, since the support member 2 and the elastic member 3 are both flexible members, when the user presses the key 20, the support member 2 and the elastic member 3 are deformed by force, so that the keycap 1 moves toward the bottom plate 10. At this time, when the elastic member 3 is deformed, part of its structure moves toward the bottom plate 10, and the elastic member 3 can contact the key switch 1021 of the bottom plate 10, thereby triggering the key switch 1021 and triggering the key 20; when the user releases the key 20, since the elastic member 3 and the support member 2 have elastic restoring force, the elastic member 3 and the support member 2 can be used to drive the keycap 1 to reset, so that the keycap 1 moves in the direction away from the bottom plate 10 until it returns to the height when it is not pressed. It can be understood that the support member 2 can also have elastic deformation ability.

[0114] Exemplarily, the material of the support member 2 may be silica gel, silicone rubber or a flexible polymer material. For example, the flexible polymer material may include SBS (Styrenic Block Copolymers, styrene-butadiene-styrene block copolymer), SIS (Styrene-Isoprene-Styrene, styrene-isoprene-styrene block copolymer), SEBS (Styrene Ethy l ene Buty l ene Styrene, hydrogenated styrene-butadiene block copolymer), EPDM (Ethylene Propy lene Diene Monomer, ethylene propylene diene monomer), POE (Polyolefin elastomer, polyolefin elastomer), TPE (Thermoplastic Elastomer, thermoplastic elastomer), TPV (Thermoplastic Vulcanizate, thermoplastic vulcanizate), TPO (Thermoplastic polyolef in, thermoplastic polyolefin), TPU (Thermoplastic polyurethanes, thermoplastic polyurethane elastomer rubber), TREE (thermoplastic polyester elastomer), PPE (polypheny lene ether, polyphenylene ether) etc. At this time, the support member 2 is easy to form a deformable structure.

[0115] Exemplarily, the material of the elastic member 3 may be silicone, silicone rubber or a flexible polymer material. For example, flexible polymer materials may include SBS (Styrenic Block Copolymers), SIS (Styrene-Isoprene-Styrene), SEBS (Styrene Ethylene Buty lene Styrene), EPDM (Ethylene Propy lene Diene Monomer), POE (Polyolefin elastomer), TPE (Thermoplastic Elastomer), TPV (Thermoplastic Vulcanizate), TPO (Thermoplastic polyolef in), TPU (Thermoplastic polyurethanes), TREE (Thermoplastic polyester elastomer), PPE (polyphenylene ether), etc. At this time, the elastic member 3 is easy to form a deformable structure.

[0116] In some examples, the materials of the elastic member 3 and the supporting member 2 may be the same or different, which is not strictly limited in this embodiment.

[0117] In some examples, when the materials of the support member 2 and the keycap 1 are different, the support member 2 and the keycap 1 can be formed independently, and the two can be integrally formed by in-mold injection molding, so that the connection between the support member 2 and the keycap 1 is more stable and reliable, thereby extending the life of the key 20.

[0118] In this embodiment, by providing a flexible support member 2 and an elastic member 3, the support member 2 and the elastic member 3 can both have strong compression deformation capabilities, so that the structure between the keycap 1 and the base plate 10 can have sufficient deformation capabilities. When the support member 2 and the elastic member 3 have a relatively low height, the key 20 can also have a sufficient key travel to achieve triggering, which is conducive to the thin design of the key 20. Since the support member 2 has a simple structure, light weight, and low cost, it is conducive to the overall thin and light design of the keyboard 200, has a relatively low cost, and has a good user experience.

[0119] When the keyboard 200 of the embodiment of the present application is applied to Figures 1 to 3 In any electronic device of the embodiment or Figure 4In the keyboard cover, the electronic device or the keyboard cover can achieve a thin and light design, with lower cost and good user experience.

[0120] In some embodiments, the rigidity of the keycap 1 may be greater than the rigidity of the support member 2. When the key 20 is subjected to force, the deformation of the keycap 1 is smaller than the deformation of the support member 2. In some examples, the keycap 1 may be a rigid structure, and when the keycap 1 is subjected to force, the pressing force can be applied to the support member 2 and the elastic member 3 synchronously, thereby pressing the support member 2 and the elastic member 3 synchronously. At this time, the force of the keycap 1 on the support member 2 and the elastic member 3, as well as the force on different parts of the support member 2 are basically consistent, which can make the deformation of the support member 2 and the elastic member 3 more consistent, which is conducive to moving the keycap 1 in a direction perpendicular to the base plate 10, thereby preventing the keycap 1 from deflecting when being pressed, and is also conducive to improving the user's feel. It can be understood that when the keycap 1 is subjected to force, the keycap 1 can produce a small rigid deformation, and the deformation of the keycap 1 can be much smaller than the deformation of the support member 2 or the elastic member 3.

[0121] For example, the keycap 1 may be made of hard plastic such as PC (Polycarbonate); or, the keycap 1 may be made of fiberglass. This embodiment does not strictly limit the material of the keycap 1. At this time, by setting the material of the keycap 1, the keycap 1 is easy to form a high-strength structure.

[0122] For example, the keycap 1 can be a roughly rectangular plate-like structure. The thickness of the keycap 1 can be relatively thin to reduce the height space occupied by the key 20. A flat plate can be formed in the middle of the keycap 1, and the flat plate can be used to fix the elastic member 3 and the support member 2. At this time, the heights of the elastic member 3 and the support member 2 can be basically the same, so that the flat plate is basically parallel to the base plate 10. A flange 11 facing the base plate 10 can be formed at the edge of the keycap 1 of the elastic member 3 and the support member 2, and the flange 11 surrounds the flat plate. The flange 11 can wrap around the end of the support member 2, and the side of the support member 2 can be fixed to the side wall of the flange 11, so that the connection between the keycap 1 and the support member 2 is tighter and more stable.

[0123] In some embodiments, the elastic member 3 may include an annular portion 31 and a trigger portion 32. The trigger portion 32 is located inside the annular portion 31 and is fixedly connected to the annular portion 31.

[0124] Among them, the annular portion 31 can be a roughly truncated cone-shaped cover structure, and the cover structure can form a cover space. The annular portion 31 can have a first end 311 and a second end 312. The first end 311 of the annular portion 31 is fixedly connected to the keycap 1, and the second end 312 of the annular portion 31 is fixedly connected to the base plate 10. The first end 311 of the annular portion 31 can be formed by a closed end of the annular portion 31, and the second end 312 of the annular portion 31 can be formed by an open end of the annular portion 31. The opening of the second end 312 of the annular portion 31 is set toward the base plate 10, and the second end 312 of the annular portion 31 can be set corresponding to the key switch 1021 of the base plate 10, and surround the peripheral side of the key switch 1021. In some examples, the first end 311 of the annular portion 31 can form the first end 33 of the elastic member 3, and the second end 312 of the annular portion 31 can form the second end 34 of the elastic member 3. Figure 8 As shown, the annular portion 31 can be the main deformation structure of the elastic member 3 after being subjected to force, and the side wall of the annular portion 31 can be arranged at an angle so as to deform after being subjected to force, thereby improving the user's pressing feel. It is understandable that the deformation of the annular portion 31 under force will affect the user's pressing feel, and the user's pressing feel can be improved by setting the shape of the annular portion 31.

[0125] The trigger portion 32 may be located in the cover space of the annular portion 31 and fixedly connected to the first end 311 of the annular portion 31. When the button 20 is not pressed, the trigger portion 32 may be located at the top side of the button switch 1021, and the trigger portion 32 may be spaced apart from the corresponding button switch 1021, that is, the trigger portion 32 does not contact the corresponding button switch 1021, so as to prevent the trigger portion 32 from triggering the button switch 1021 and causing an accidental touch when the button 20 is not pressed. The trigger portion 32 may be generally cylindrical in structure. Exemplarily, the trigger portion 32 may deform the button switch 1021 by pressing the button switch 1021, thereby realizing the conduction of the button switch 1021, that is, the triggering of the button 20. In some other examples, the surface of the trigger portion 32 facing the button switch 1021 may be conductive, and the trigger portion 32 may electrically conduct the button switch 1021, thereby realizing the conduction of the button switch 1021, that is, the triggering of the button 20.

[0126] In some examples, the annular portion 31 and the trigger portion 32 may be integrally formed. For example, the elastic member 3 is formed by a process such as injection molding, thereby directly forming the annular portion 31 and the trigger portion 32 .

[0127] In some embodiments, the hardness of the elastic member 3 may be greater than the hardness of the support member 2. At this time, the support member 2 is more likely to deform relative to the elastic member 3. When the keycap 1 is under pressure, the elastic member 3 will mainly provide an elastic reaction force acting on the keycap 1. The elastic force curve of the elastic member 3 after being stressed will mainly affect the pressing feel of the key 20. After the key 20 is pressed and loses the pressing force, the support member 2 applies an elastic force to the keycap 1 to restore the keycap 1 to its initial position. When the key 20 is in an unpressed state, the support member 2 can be the main supporting structure of the keycap 1. In this example, by setting the hardness of the elastic member 3 and the support member 2, it is beneficial to design the shape of the elastic member 3 so that the elastic force curve of the elastic member 3 after being pressed is more in line with the user's feel, which is beneficial to improving the user's experience.

[0128] For example, the hardness of the elastic member 3 may be 40 degrees Shore hardness, and the hardness of the support member 2 may be 20 degrees Shore hardness, but it is not strictly limited thereto. At this time, the elastic member 3 and the support member 2 have good deformation ability and support ability.

[0129] In some embodiments, the compression ratios of the support member 2 and the elastic member 3 may be greater than or equal to 2. The compression ratio of the support member 2 refers to the ratio of the height of the support member 2 when not pressed to the height when compressed to the lowest point, and the compression ratio of the elastic member 3 refers to the ratio of the height of the elastic member 3 when not pressed to the height when compressed to the lowest point.

[0130] For example, the compression ratio of the support member 2 and the elastic member 3 can be 2.5, 3, 3.5, 4, etc. The compression ratios of the support member 2 and the elastic member 3 can be the same or different, and this embodiment will not list them one by one. Among them, the compression ratio of the support member 2 and the elastic member 3 can be obtained under a pressing force close to that in actual use, for example, the pressing force is 1.5N (Newton).

[0131] In the present embodiment, both the support member 2 and the elastic member 3 have a strong deformation ability, so that the support member 2 and the elastic member 3 can have a large displacement in the height direction (i.e., the Z direction) when they have a relatively low height, that is, the key 20 can have a relatively large key travel. At this time, the height of the key 20 can be as low as less than 1 mm, which greatly reduces the thickness and weight of the keyboard 200, and does not require a complex supporting structure to support the keycap 1, so that the cost of the keyboard 200 is relatively low. Of course, the height of the key 20 can also be higher than 1 mm. For example, the thickness of the key 20 can be 3 mm, so as to take into account the user's feel. In this example, by setting the compression ratio of the support member 2 and the elastic member 3, it is convenient to set the height of the key 20 to be relatively low, which can further make the key 20 more lightweight and thin, thereby facilitating the lightweight design of the keyboard 200.

[0132] In some embodiments, the compression ratio of the support member 2 may be greater than the compression ratio of the elastic member 3. At this time, when the key 20 is compressed, the compressibility of the support member 2 is greater than the compressibility of the elastic member 3, so as to avoid the support member 2 from limiting the pressing degree of the key 20, thereby avoiding the support member 2 from having too much influence on the pressing feel when the key 20 is pressed. It can be understood that, since the compression ratio of the support member 2 can be greater than the compression ratio of the elastic member 3, when the height of the support member 2 and the elastic member 3 are similar, the maximum compression amount of the support member 2 can be greater than the maximum compression amount of the elastic member 3, but when the key 20 is pressed, since the support member 2 and the elastic member 3 support the keycap 1 at the same time, the heights of the support member 2 and the elastic member 3 after compression can be the same.

[0133] In some embodiments, the support member 2 is disposed around the elastic member 3. In this case, there may be a gap between the support member 2 and the elastic member 3, and the support member 2 is distributed around the elastic member 3, so that the keycap 1 is equivalent to having a two-layer support structure, i.e., the inner elastic member 3 and the outer support member 2, which has a better support capacity for the keycap 1.

[0134] Exemplarily, the ring formed by the support member 2 can be set corresponding to the shape of the keycap 1. The support member 2 is set corresponding to the edge of the keycap 1, so that the edge of the keycap 1 is evenly supported by the support member 2, so that when the keycap 1 is pressed and rebounds, the keycap 1 is not easy to deviate.

[0135] Exemplarily, the side wall of the support member 2 may be provided with a through hole 23. The through hole 23 connects the inner side and the outer side of the support member 2. There may be multiple through holes 23, and the shapes and sizes of the multiple through holes 23 may be the same, and the through holes 23 may be evenly distributed on the support member 2. For example, the support member 2 has four side walls connected in sequence, and each side wall may have three through holes 23 evenly arranged side by side. In this example, by providing the through holes 23 on the support member 2, the support member 2 is more easily compressed when subjected to force, thereby improving the compressibility of the support member 2, and reducing the supporting force of the support member 2 on the keycap 1, thereby reducing the influence of the support member 2 on the pressing feel when the user presses the key 20. In addition, the through holes 23 enable air to circulate inside and outside the support member 2, thereby preventing a pressure difference between the inside and outside of the support member 2 when the key 20 is pressed, which is beneficial to the deformation of the support member 2 and improves the pressing feel of the user.

[0136] In some examples, the shape of the through hole 23 may be substantially elliptical. An ellipse has a major axis and a minor axis. For example, the major axis of the through hole 23 may be perpendicular to the height direction of the keyboard 200, and the minor axis of the through hole 23 may be parallel to the height direction of the keyboard 200. In this case, the structure at the through hole 23 is more likely to deform along the minor axis direction of the through hole 23, so that the support member 2 is more likely to deform along the height direction of the keyboard 200, reducing deformation perpendicular to the height direction of the keyboard 200, thereby reducing the displacement of the key 20 during the pressing process.

[0137] Please refer to Fig. 9 and Fig.10 , Fig. 9 yes Figure 5 The structure diagram of the keyboard 200 shown in FIG. 2 is a partial structure of the keyboard 200 in other embodiments. Fig.10 yes Figure 5 The partial structure of the keyboard 200 is shown in the structural diagram of some other embodiments. Fig. 9 and Fig.10 The keyboard 200 shown in the embodiment may include Figure 6 Most of the technical features of the keyboard 200 shown in the embodiment are described below mainly in terms of the differences between the two, and most of the common technical contents between the two are not repeated.

[0138] In some embodiments, Fig. 9 Example Fig.10 The keyboard 200 shown in the embodiment is Figure 6 The main difference of the keyboard 200 shown in the embodiment is the shape of the through hole 23.

[0139] In some embodiments, Fig. 9 As shown, the shape of the through hole 23 can be roughly rectangular. Exemplarily, the length direction of the rectangular through hole 23 can be parallel to the height direction of the keyboard 200. The length of the rectangular hole can be greater than or equal to half the height of the key 20, but is not strictly limited to this. The number of through holes 23 can refer to Figure 6 Description of the embodiments.

[0140] In some embodiments, Fig.10 As shown, the shape of the through hole 23 can be roughly circular. For example, the center of the circular through hole 23 can be located at the upper half of the support member 2, so that the upper part of the support member 2 is more likely to deform when a force is applied to the support member 2. The number of through holes 23 can refer to Figure 6 Description of the embodiments.

[0141] See also Fig.11 , Fig.11 yes Figure 5 Part of the structure of the keyboard 200 is shown in the structural diagram of some other embodiments. Fig.11 The keyboard 200 shown in the embodiment may include Figure 6 Most of the technical features of the keyboard 200 shown in the embodiment are described below mainly in terms of the differences between the two, and most of the common technical contents between the two are not repeated.

[0142] In some embodiments, Fig.11 The keyboard 200 shown in the embodiment is Figure 6The main difference of the keyboard 200 shown in the embodiment is the arrangement of the support member 2. The side wall of the support member 2 is arranged in a curved surface, and the middle part of the side wall of the support member 2 protrudes in a direction away from the elastic member 3 relative to the two ends. It can be understood that in the height direction of the keyboard 200 (i.e., the Z direction), the middle part of the support member 2 is located between the two ends thereof.

[0143] Among them, the middle part and both ends of the support member 2 are smoothly connected, and the cross section of the side wall of the support member 2 is roughly in a "C" shape. Since the middle part of the side of the support member 2 protrudes outward, when the key cap 1 is subjected to force, the middle part of the side wall of the support member 2 will be deformed first, and the deformation direction of the middle part is in the direction away from the elastic member 3, so that the overall deformation direction of the support member 2 is in the height direction of the keyboard 200. At this time, since the support member 2 is bent, the support member 2 does not need a large force to deform. When the key 20 is pressed, the reaction force of the support member 2 on the key cap 1 is small, and the impact on the pressing feel is small. It is only necessary to mainly design the elastic member 3 to determine the pressing feel of the key 20, thereby simplifying the complexity of the design of the key 20. In addition, the partial structure of the support member 2 is deformed in the direction away from the support member 2, which is conducive to making the support member 2 have a larger compression ratio in the height direction of the keyboard 200, thereby facilitating the thin design of the key 20, that is, facilitating the thin design of the keyboard 200.

[0144] For the material, position and connection method of the support 2 and other parts of the support 2, please refer to Figure 6 The relevant descriptions in the embodiments are not repeated in this embodiment.

[0145] See also Fig.12 , Fig.12 yes Figure 5 The structure of the keyboard 200 is shown in some other embodiments. Fig.12 The keyboard 200 shown in the embodiment may include Figure 6 Most of the technical features of the keyboard 200 shown in the embodiment are described below mainly in terms of the differences between the two, and most of the common technical contents between the two are not repeated.

[0146] In some embodiments, Fig.12 The keyboard 200 shown in the embodiment is Figure 6 The main difference of the keyboard 200 shown in the embodiment lies in the arrangement of the support member 2 .

[0147] The side wall of the support member 2 includes a first wall plate 24 and a second wall plate 25. One end of the first wall plate 24 is fixedly connected to the keycap 1, and the other end is fixedly connected to the bottom plate 10. One end of the second wall plate 25 is fixedly connected to the keycap 1, and the other end is fixedly connected to the bottom plate 10. The first wall plate 24 and the second wall plate 25 are arranged crosswise.

[0148] At this time, the cross-section of the side wall of the support member 2 parallel to the Z direction is roughly in the shape of an "X". In the height direction of the keyboard 200, the intersection of the first wall panel 24 and the second wall panel 25 is located in the middle of the support member 2. In the upper and lower parts of the intersection, a "V"-shaped structure can be formed between the first wall panel 24 and the second wall panel 25, respectively. When the keycap 1 is subjected to force, the intersection of the support member 2 hardly deforms, and the upper and lower parts of the support member 2 (that is, the two "V"-shaped structures) can both deform to compress the support member 2. Among them, the upper and lower parts of the support member 2 can mainly undergo bending deformation.

[0149] For the material, position and connection method of the support 2 and other components, please refer to Figure 6 The relevant descriptions in the embodiments are not repeated in this embodiment.

[0150] In the present embodiment, since the first wall panel 24 and the second wall panel 25 of the support member 2 intersect with each other, the side wall of the support member 2 has a wider width, and the force exerted by the key 20 on the support member 2 is easy to overlap with the support member 2, so that the support member 2 has a better anti-deflection ability, that is, the support member 2 has a better deformation ability in the height direction of the keyboard 200, and is not easy to deflect or move in the height direction perpendicular to the keyboard 200, thereby improving the pressing feel and enhancing the user experience.

[0151] See also Fig.13 , Fig.13 yes Figure 5 The partial structure of the keyboard 200 shown is a schematic diagram of the structure of some other embodiments. Fig.13 The keyboard 200 shown in the embodiment may include Figure 6 Most of the technical features of the keyboard 200 shown in the embodiment are described below mainly in terms of the differences between the two, and most of the common technical contents between the two are not repeated.

[0152] In some embodiments, Fig.13 The keyboard 200 shown in the embodiment is Figure 6 The main difference of the keyboard 200 shown in the embodiment lies in the arrangement of the support member 2 .

[0153] The side wall of the support member 2 includes a third wall plate 26 and a fourth wall plate 27. One end of the third wall plate 26 is fixedly connected to the keycap 1, and the other end is fixedly connected to the bottom plate 10. One end of the fourth wall plate 27 is connected to the third wall plate 26, and the other end is fixedly connected to the bottom plate 10. The fourth wall plate 27 is located on a side of the third wall plate 26 close to the elastic member 3.

[0154] At this time, the cross section of the side wall of the support member 2 may be roughly in an inverted "Y" shape. In the height direction of the keyboard 200, the connection between the third wall plate 26 and the fourth wall plate 27 may be located in the middle of the support member 2, and an inverted "V" shape may be formed between the third wall plate 26 and the fourth wall plate 27 at the lower part of the connection. When the keycap 1 is subjected to force, the upper half of the connection of the support member 2 may mainly undergo compression deformation, and the lower half of the connection may mainly undergo compression deformation and bending deformation.

[0155] For the material, position and connection method of the support 2 and other parts of the support 2, please refer to Figure 6 The relevant descriptions in the embodiments are not repeated in this embodiment.

[0156] In this embodiment, since the support member 2 is connected to the bottom plate 10 through the third wall plate 26 and the fourth wall plate 27, the connection width between the support member 2 and the bottom plate 10 is relatively wide, and the support member 2 is not easy to deflect when deformed; since the support member 2 is connected to the keycap 1 through the third wall plate 26, the support member 2 is easy to deform. Fig.12 The support member 2 of the embodiment has both moderate anti-deflection capability and easy pressing capability, and provides a good user experience.
