[0001] This application relates to the field of computer equipment technology, and more specifically, to an input device and an electronic device. Background Technology

[0002] In the design and development of laptops, thinness and lightness have always been core development trends. As a core input component of laptops, the structural design of the input device directly affects the overall thickness and user experience. In current laptop input device designs, to ensure normal input operation, a 1.6~1.8mm key travel height must be reserved for the keycaps. Combined with the thickness of the input device itself, the overall vertical thickness of the input device module in the system is approximately 4.0mm. This part of the structure occupies a certain amount of space inside the laptop, becoming a significant factor restricting further thinness and lightness of the entire machine.

[0005] According to an embodiment of this application, when the ramp surface slides close to the guide wall, the keycap slides into the keycap hole, and the side of the keycap away from the base plate is flush with the side of the panel away from the base plate; when the ramp surface slides away from the guide wall, the keycap slides out of the keycap hole, and the side of the keycap away from the base plate protrudes from the side of the panel away from the base plate.

[0006] According to an embodiment of this application, the driving mechanism includes: an eccentric shaft sleeved on a rotating shaft, the axis of the eccentric shaft coinciding with the axis of the rotating shaft; a slider in contact with the circumferential sidewall of the eccentric shaft, wherein when the eccentric shaft rotates around its axis, the slider is driven by the eccentric shaft to reciprocate along a first direction; and a receiving seat connected to the slider and a base plate, configured to drive the base plate to reciprocate along the first direction under the drive of the slider.

[0007] According to an embodiment of this application, the circumferential sidewall of the eccentric shaft has at least a first position, a second position, and a third position; from the first position to the second position, the eccentric radius gradually increases; from the second position to the third position, the eccentric radius remains unchanged.

[0008] According to an embodiment of this application, the driving mechanism further includes: a first elastic member extending along a first direction, one end of which is connected to the side of the slider away from the eccentric axis, and the other end is fixed to a fixed seat, configured to provide a force toward the eccentric axis to the slider; a second elastic member disposed in a receiving seat along the first direction, one end of which is connected to a base plate, and the other end of which is connected to a panel, configured to provide a tension force to the base plate; a connecting member connecting the slider and the receiving seat in the first direction; and a slide rail for providing a track for the slider to move along the first direction.

[0009] According to an embodiment of this application, the keycap is connected to the base plate via a support member. When the keycap slides into the keycap hole, the support member is compressed in the second direction; when the keycap slides out of the keycap hole, the support member extends in the second direction.

[0010] According to an embodiment of this application, the side of the panel facing the base plate has a buffer layer, and the guide wall is located on the buffer layer.

[0011] According to an embodiment of this application, a slide groove is provided on the side of the panel facing the base plate, and a buffer member is provided on the side of the receiving seat facing the slide groove.

When the keycap slides into the keycap hole, the keycap can be flush with or lower than the panel, so that the electronic device no longer needs to reserve extra vertical space for the key press stroke when closed, significantly reducing the overall thickness of the device when closed, which is conducive to the realization of a thin and light design of the device; at the same time, after the keycap slides out of the keycap hole, it can still ensure that the keycap has sufficient press stroke and support stability, ensuring a good input operation experience.

Detailed Implementation

[0026] The embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of this application. In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the embodiments of this application for ease of explanation. However, it will be apparent that one or more embodiments may be implemented without these specific details. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0027] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0028] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0029] When using expressions such as "at least one of A, B and C", they should generally be interpreted in accordance with the meaning that is commonly understood by those skilled in the art (e.g., "a system having at least one of A, B and C" should include, but is not limited to, a system having A alone, a system having B alone, a system having C alone, a system having A and B, a system having A and C, a system having B and C, and / or a system having A, B and C, etc.).

[0030] In related technologies, two solutions have been proposed to address the problem of excessive vertical space occupied by input devices: 1. Reduce the key travel height of the input device keycaps, for example, reducing the key travel from 1.6mm to 1.2mm. However, shortening the key travel results in insufficient key feedback and unclear key triggering, reducing the typing feel and experience. Furthermore, the key trigger point is too close to the key travel, increasing the probability of accidental touches. Insufficient key rebound force can also lead to incomplete pressing and inaccurate input. In addition, users need to exert extra force to confirm whether the key has been successfully triggered, which can easily cause hand fatigue. 2. Adopt an ultra-thin input device structure. By changing the structural form of the input device body, the overall thickness of the input device can be further reduced. However, the dust-holding capacity of the ultra-thin input device structure is greatly reduced. During use, dust and debris can easily enter, causing key jamming and malfunction. Moreover, this type of ultra-thin structure has a high degree of integration, is difficult to disassemble and repair, and has a significantly higher overall failure rate compared to traditional input devices.

[0031] According to an embodiment of this application, the input device includes: a key assembly including a base plate and a plurality of keycaps, the base plate being located on a first plane, the keycaps being connected to the base plate in a second direction, the second direction being perpendicular to the first plane; a panel being arranged parallel to the base plate, the panel having a plurality of keycap holes for accommodating the plurality of keycaps; a drive mechanism having one end connected to a rotating shaft and the other end connected to the base plate, the drive mechanism being configured to drive the base plate to reciprocate along a first direction in the first plane in response to rotation of the rotating shaft; wherein, the keycaps have a ramp surface, the keycap hole and the opposite surface of the ramp surface have a guide wall, when the base plate reciprocates along the first direction, the ramp surface and the guide wall slide relative to each other along the first direction, so that the keycap slides into / out of the keycap hole.

[0032] According to the embodiments of this application, the input device, by setting the base plate on a first plane and connecting the keycaps to the base plate along a second direction perpendicular to the first plane, combined with the sliding fit structure of the ramp surface and the guide wall, enables the keycaps to move up and down relative to the keycap holes during the horizontal movement of the base plate along the first direction. When the keycaps slide into the keycap holes, the keycaps can be flush with or lower than the panel, so that the electronic device no longer needs to reserve extra vertical space for the key pressing stroke in the closed state, significantly reducing the overall thickness of the device in the closed state, which is conducive to the realization of a thin and light design of the device; at the same time, after the keycaps slide out of the keycap holes, the keycaps can still be guaranteed to have sufficient pressing stroke and support stability, ensuring a good input operation experience.

[0033] Figure 1 A schematic front view of an input device according to an embodiment of this application is shown. Figure 2 A schematic top view illustrating the connection between the drive mechanism and the base plate according to an embodiment of this application is shown. Figure 3 A side view of the drive mechanism according to an embodiment of this application is shown schematically. Figure 4A schematic side view of an eccentric shaft sleeved on a rotating shaft according to an embodiment of the present application is shown.

[0034] According to an embodiment of this application, the input device includes a button assembly, a panel 1, and a drive mechanism. The button assembly includes components located on a first plane (…). Figure 1 The base plate 2 (shown in the XY plane) is connected to the drive mechanism.

[0035] According to an embodiment of this application, the drive mechanism includes an eccentric shaft 31, a slider 32, a receiving seat 33, a first elastic element 34, a second elastic element 35, a connecting element 36, and a slide rail 37.

[0036] According to an embodiment of this application, an eccentric shaft 31 is sleeved on a rotating shaft 4, the axis of the eccentric shaft 31 coincides with the axis of the rotating shaft 4, and the eccentric shaft 31 and the rotating shaft 4 rotate synchronously. Figure 4 As shown, the circumferential sidewall of the eccentric shaft 31 has at least a first position 311, a second position 312, and a third position 313. From the first position 311 to the second position 312, the eccentric radius gradually increases; from the second position 312 to the third position 313, the eccentric radius remains unchanged. Before the rotating shaft 4 rotates, the first position 311 of the eccentric shaft 31 is in contact with the slider 32; the rotating shaft 4 rotates counterclockwise until the second position 312 of the eccentric shaft 31 contacts the slider 32. Because the eccentric radius gradually increases during the rotation, the eccentric shaft 31 pushes the slider 32 along the first direction (…). Figure 3 (As shown in the Y-axis direction); the rotating shaft 4 rotates counterclockwise until the third position 313 of the eccentric shaft 31 contacts the slider 32. Since the eccentric radius remains unchanged during the rotation, the relative position of the eccentric shaft 31 and the slider 32 remains unchanged. In some embodiments, the angle between the first position 311 and the second position 312 can be 90°, and the angle between the second position 312 and the third position 313 can be 45°. It is understood that the angle between the first position 311, the second position 312, and the third position 313 can be other angles; the circumferential sidewall of the eccentric shaft 31 can also have other positions besides the first position 311, the second position 312, and the third position 313, which can be set according to the movement path of the slider 32. The difference between the eccentric radius of the second position 312 and the first position 311 can be set according to the actual situation. For example, the eccentric radius of the first position 311 can be 4mm, the eccentric radius of the second position 312 can be 7mm, and the difference between the two can be 3mm.

[0037] According to an embodiment of this application, in a first direction, one end of the slider 32 contacts the circumferential sidewall of the eccentric shaft 31, and the other end is connected to the first elastic member 34. The first elastic member 34 extends along the first direction, and its end away from the slider 32 is fixed to the fixed seat 38, presenting a compressed state. As the eccentric radius gradually increases during the rotation of the eccentric shaft 31, the slider 32 is driven by the eccentric shaft 31 to move away from the eccentric shaft 31 along the first direction; as the eccentric radius gradually decreases during the rotation of the eccentric shaft 31, the first elastic member 34 provides a force to the slider 32 toward the eccentric shaft 31, so that the slider 32 always abuts against the eccentric shaft 31, thereby enabling the slider 32 to reciprocate along the first direction as the eccentric shaft 31 rotates. During this process, the maximum moving distance of the slider 32 depends on the difference between the eccentric radius of the second position 312 and the first position 311 of the eccentric shaft 31. For example, when the difference is 3mm, the maximum moving distance of the slider 32 is 3mm.

[0038] According to an embodiment of this application, the position of the slide rail 37 is fixed, which provides a track for the slider 32 to move in a first direction, so that the slider 32 can reciprocate in the first direction without deviating under the limit of the slide rail 37.

[0039] According to an embodiment of this application, the receiving seat 33 and the slider 32 are connected by a connector 36. When the slider 32 moves back and forth in the first direction, the receiving seat 33 can be moved back and forth in the first direction synchronously through the connector 36. In addition, the receiving seat 33 is also connected to the base plate 2, thereby synchronously driving the base plate 2 to move back and forth in the first direction.

[0040] According to an embodiment of this application, a second elastic member 35 is disposed in the receiving seat 33 along a first direction, with one end connected to the base plate 2 and the other end connected to the panel 1. The second elastic member 35 is in a stretched state and can provide tension to the base plate 2.

[0041] According to an embodiment of this application, a groove 13 is provided on the side of the panel 1 facing the base plate 2, and a buffer member 39 is provided on the side of the receiving seat 33 facing the groove 13. The buffer member 39 can move synchronously with the receiving seat 33 in the groove 13 along the first direction. The buffer member 39 is made of a material with a low coefficient of friction, such as polyoxymethylene. On the one hand, the buffer member 39 can effectively reduce the sliding friction coefficient between the receiving seat 33 and the inner wall of the groove 13, ensuring that when the receiving seat 33 moves back and forth with the base plate 2 along the first direction, the movement process in the groove 13 is smooth without jamming or abnormal noise, avoiding impact and scratching wear between the two, and effectively improving the movement stability and overall service life of the sliding fit structure; on the other hand, it can form a movement guide for the receiving seat 33, and further form a movement guide for the base plate 2, limiting it to only moving in a straight line along the first direction, avoiding deviation.

[0042] Figure 5A schematic top view of a support plate according to an embodiment of this application is shown.

[0043] like Figure 1 As shown, the input device also includes a support plate 5, located on the side of the base plate 2 away from the panel 1. The support plate 5 is fixedly connected to the panel 1 by fasteners 6. Figure 5 As shown, the support plate 5 has a first direction ( Figure 5 An arc-shaped portion 50 extending in the Y-axis direction (as shown), and multiple arc-shaped portions 50 in Figure 5 The arrangement is spaced apart along the X-axis as shown.

[0044] According to an embodiment of this application, the arc-shaped portion 50 bends from the support plate 5 toward the side closer to the base plate 2 to support the base plate 2. The arc-shaped portion 50 can reduce the contact area between the support plate 5 and the base plate 2, thereby reducing the friction between the support plate 5 and the base plate 2 when the base plate 2 reciprocates along the first direction, making the movement of the base plate 2 smoother.

[0045] Figure 6 A schematic side view of a keycap sliding into a keycap hole according to an embodiment of this application is shown. Figure 7 A schematic side view of a keycap sliding out of a keycap hole according to an embodiment of this application is shown.

[0046] According to an embodiment of this application, the button assembly includes a base plate 2 and a plurality of keycaps 7, the keycaps 7 being in a second direction ( Figure 7 The keycap 7 is connected to the base plate 2 via a support member 8 along the Z-axis direction. In some embodiments, the support member 8 is an X-shaped cross-hinged linkage structure, with one end hinged to the keycap 7 and the other end slidably hinged to the base plate 2, which can limit the pressing and rebounding movement of the keycap 7 in the second direction, ensuring the pressing force stroke and uniform pressing feel of the keycap 7.

[0047] According to an embodiment of this application, the panel 1 and the base plate 2 are arranged parallel to each other, and the panel 1 has a plurality of keycap holes 10 for accommodating a plurality of keycaps 7. When the base plate 2 is along a first direction ( Figure 6 When the keycap 7 reciprocates in the Y-axis direction (as shown), it can slide into / out of the keycap hole 10 along the first direction, for example, as Figure 6 As shown, when the base plate 2 along Figure 6 When the keycap 7 moves in the positive Y-axis direction, as shown, it slides into the keycap hole 10, and the support 8 is compressed in the second direction; as shown Figure 7 As shown, when the base plate 2 along Figure 7 When the keycap 7 moves in the negative Y-axis direction, as shown, the keycap 7 slides out of the keycap hole 10, and the support member 8 extends in the second direction. During this process, the support member 8 can prevent the keycap 7 from shifting or loosening, achieving structural stability of the keycap 7 in the sliding-in / sliding-out state. In addition, the X-shaped cross-hinged linkage structure of the support member 8 is adapted to the low space occupation requirements when the input device is stored, while taking into account the overall thin and light design.

[0048] According to an embodiment of this application, the keycap 7 has a ramp surface 70 with an inclination angle of θ; the keycap hole 10 and the opposite surface of the ramp surface 70 have a guide wall 12. When the base plate 2 reciprocates along the first direction, the ramp surface 70 and the guide wall 12 maintain abutment and slide relative to each other along the guide wall 12. By utilizing the mechanical guidance and force transmission of the ramp surface, the horizontal displacement of the base plate 2 is converted into the vertical displacement of the keycap 7 along the second direction, so that the keycap 7 can slide into / out of the keycap hole 10, realizing the switching between the use state of the keycap 7 extending out of the keycap hole 10 and the hidden state of being stored in the keycap hole 10.

[0049] According to the embodiments of this application, in the hidden state where the keycap 7 is housed within the keycap hole 10, the side of the keycap 7 away from the base plate 2 can be flush with or lower than the side of the panel 1 away from the base plate 2; in the used state where the keycap 7 extends out of the keycap hole 10, the side of the keycap 7 away from the base plate 2 protrudes beyond the side of the panel 1 away from the base plate 2. During this process, the maximum movement distance of the keycap 7 in the second direction depends on the maximum movement distance of the keycap 7 in the first direction and the inclination angle θ of the ramp surface 70. That is, the inclination angle θ of the ramp surface 70 can be designed based on the maximum movement distance of the keycap 7 in the first and second directions. For example, the maximum movement distance of the keycap 7 in the first direction is the same as that of the slider 32, which can be 3mm; the maximum movement distance of the keycap 7 in the second direction can be 1.6mm; and the inclination angle θ can be... .

[0050] According to an embodiment of this application, the side of panel 1 facing the base plate 2 has a buffer layer 11, and a guide wall 12 is located on the buffer layer 11. The buffer layer 11 is made of a material with a low coefficient of friction, such as polyoxymethylene, which can reduce the friction between the ramp surface 70 and the guide wall 12 during relative sliding, ensuring a smooth sliding process.

[0051] According to embodiments of this application, the keycap 7 can be made of a material with a low coefficient of friction, such as polyoxymethylene; or it can be made of acrylonitrile-butadiene-styrene copolymer as a substrate, with a polytetrafluoroethylene dry lubricating coating formed on its surface, in order to reduce the coefficient of friction between the keycap 7 and the guide wall 12 and improve the surface wear resistance.

[0052] The working principle of the input device provided in the embodiments of this application is as follows:

[0053] In the initial state, the first position 311 of the eccentric shaft 31 is in contact with the slider 32, such as... Figure 6 As shown, at this time, the keycap 7 is stored in the keycap hole 10, and the side of the keycap 7 away from the base plate 2 is flush with the side of the panel 1 away from the base plate 2.

[0054] Next, refer to Figure 4 As shown, the rotating shaft 4 rotates counterclockwise until the second position 312 of the eccentric shaft 31 contacts the slider 32. Because the eccentric radius gradually increases during rotation, the eccentric shaft 31 pushes the slider 32 along the first direction (…). Figure 3 (As shown in the Y-axis direction) moving away, slider 32 drives base plate 2 to move, and keycap 7 slides out of keycap hole 10 under the action of base plate 2, as shown. Figure 7 As shown, keycap 7 is in use at this time.

[0055] Next, refer to Figure 4 As shown, the rotating shaft 4 continues to rotate counterclockwise until the third position 313 of the eccentric shaft 31 contacts the slider 32. Since the eccentric radius remains unchanged during the rotation, the relative position of the eccentric shaft 31 and the slider 32 remains unchanged, and the keycap 7 remains in the position of the slider. Figure 7 The usage status is shown.

[0056] Understandably, when the rotating shaft 4 rotates clockwise, the third position 313 and the second position 312 of the eccentric shaft 31 successively contact the slider 32. During this process, the eccentric radius remains unchanged, and the keycap 7 is in a position... Figure 7 The usage state is shown below; when the rotating shaft 4 continues to rotate clockwise until the first position 311 of the eccentric shaft 31 contacts the slider 32, the eccentric radius gradually decreases during this process. The slider 32 is subjected to a force provided by the first elastic element 34 towards the eccentric shaft 31, so that the slider 32 always abuts against the eccentric shaft 31, causing the slider 32 to move closer to the eccentric shaft 31. At the same time, it drives the base plate 2 to move closer to the eccentric shaft 31. The keycap 7 slides into the keycap hole 10 under the action of the base plate 2, as shown. Figure 6 As shown, the keycap 7 is housed in the keycap hole 10, with the side of the keycap 7 away from the base plate 2 flush with the side of the panel 1 away from the base plate 2.

[0057] Embodiments of this application also provide an electronic device, including a first body, a second body, and an input device, wherein the input device is the input device described above, and specific details can be found in the description of the input device described above. Figures 1-7 The description will not be repeated here.

[0058] According to the embodiments of this application, referring to Figure 2 As shown, the first body is provided with a fixing member 9, and the second body is connected to the rotating shaft 4. The fixing member 9 is connected to the rotating shaft 4, thus the first body and the second body are rotatably connected via the rotating shaft 4. The first body and the second body can open and close relative to each other around the rotating shaft 4 to form an opening and closing angle. When the first body and the second body are in the closed state, the side of the keycap 7 away from the base plate 2 is flush with the side of the panel 1 away from the base plate 2. When the first body and the second body open and close relative to each other around the rotating shaft, driven by the driving mechanism, the keycap 7 slides out of the keycap hole 10, causing the side of the keycap 7 away from the base plate 2 to protrude beyond the side of the panel 1 away from the base plate 2.
