Various modifications and changes may be made in the details of the present description without departing from the spirit of the application, which is also based on different perspectives and applications. In particular, the relative proportions and positions of the various elements in the drawings are exemplary only, and are not intended to represent the actual conditions in which the present application is practiced.
As shown in fig. 1 to 5, fig. 1 is a partial schematic structural diagram of an embodiment of an electronic device 3 and a keyboard 1 thereof. Fig. 2 to 4 are partial schematic structural diagrams of the electronic device 3 and the keyboard 1 thereof according to other embodiments of the present application. Fig. 5 is a partial perspective view of the electronic device 3 and the keyboard 1 thereof according to another embodiment of the present application, and the section a-a may show a partial sectional structure shown in fig. 1 to 4.
As shown in fig. 5, the electronic device 3 of the present application mainly includes a casing (partially shown, not labeled), a keyboard 1, and a motherboard (not shown; usually including a processor, a memory, an input/output bus, necessary hardware components, a firmware installed with a bios, application software, and driving hardware components, etc.); in some examples, the electronic device 3 further includes a screen electrically connected to the main board. The housing comprises an upper device shell 31 and a lower device shell (disposed below the upper device shell 31, not shown); the device top case 31 has one or more second key caps 121 or 121' (or at least one second key cap) and a through hole array 35, and the through hole array 35 includes a plurality of through holes 32 located within the dotted line labeled 35 in fig. 5. The second key cap 121 or 121' is located outside the perforated array 35. The keyboard 1 is installed below a device upper shell 31 of the electronic device 3, and the keyboard 1 mainly includes a plurality of first keys 11, one or more second keys 12 (or 12'), and a keyboard circuit board 13.
As shown in fig. 1 to 5, the keyboard circuit board 13 has a substrate, a first trigger circuit 131, a second trigger circuit 132, a plurality of switch pads 133, and a single or a plurality of proximity sensors 134 (or at least one proximity sensor 134), which are respectively disposed on the substrate of the keyboard circuit board 13 with a single-layer or multi-layer structure (in the embodiment of fig. 1 to 4, the keyboard circuit board 13 is a single-layer substrate, and in other embodiments, the keyboard circuit board 13 may include a multi-layer substrate). Wherein, each switch pad 133 is located below the first trigger 113 of each first button 11 and electrically connected to the first trigger circuit 131; the first trigger circuit 131 may be, for example, a key matrix circuit, which generates a keyboard input signal output according to a scanning result of a key matrix formed by all the first keys 11. In the present application, at least a portion of the proximity sensor 134, the substrate and the second trigger circuit 132 extends below the second keycap 121/121', refer to the proximity sensor 134 and the second trigger circuit 132 in the right half of fig. 1-4, and the substrate of the keyboard circuit board 13 in fig. 5 exceeds the area of the through hole array 35 (the edge of the substrate of the keyboard circuit board 13 is shown by the dashed outer circle line in fig. 5). The proximity sensor 134 is located under the second key cap 121/121 'or the second trigger 123 of the second key 12/12', and is electrically connected to the second trigger circuit 132. The keypad Circuit board 13 may have a single-layer or multi-layer Circuit structure, such as a rigid Printed Circuit Board (PCB), a film Circuit board (film Circuit), or a flexible Circuit board (FPC). In the present application, the second trigger circuit 132 may be electrically connected to a power wake-up circuit or a component start-up circuit (light emitting/wireless/body recognition … component) on the main board of the electronic device 3 alone, or a function-specific trigger circuit, or be electrically connected to the main board of the electronic device 3 together with the first trigger circuit 131 through the keyboard interface. The proximity sensor may be implemented by a capacitive, resistive, magnetic sensor or other sensor, which senses the capacitance change, resistance change, and magnetic flux change between the second trigger 123 and the proximity sensor 134 during the pressing process of the second key cap 121/121'. In other embodiments, multiple sensor applications may be provided simultaneously.
Each first key 11 has a first key cap 111, a first reset member 112 and a first trigger member 113. If necessary, the first key 11 further comprises a support mechanism 20, and the keyboard 1 further comprises a bottom plate 17; the support mechanism 20 comprises two supports (no symbols are assigned independently) which are each rotatably and/or movably connected between the first key cap 111 and the base 17. The support mechanism 20 may keep the first key cap 111 balanced during lowering, but is not absolutely necessary to realize the present application. The first key caps 111 are covers with a substantially planar upper surface, and each of the first key caps 111 may have the same or different size, but all protrude from each of the through holes 32 of the through hole array 35 of the device upper shell 31 to be exposed on the upper surface of the device upper shell 31. The first reset member 112 (e.g., a rubber cylinder or a vertical spring) is disposed between the first key cap 111 and the keyboard circuit board 13, and is used for supporting the first key cap 111 when the first key cap 111 moves toward or away from the keyboard circuit board 13, and providing a reset force to make the first key 11/the first key cap 111 move upward to return to the original height/position after being released by the pressing force. Although the frame mechanism 20 is shown in fig. 1-4 as an X-shaped (scissors foot) structure in which the middle sections of the two frames are pivotally connected to each other, the connecting section 21 at the bottom side of the two frames of the frame mechanism 20 is rotatably and/or movably connected to the connecting section 170 of the bottom plate 17. The bottom plate 17 may be made of metal, and the connecting portion 170 is a hook formed by punching and bending the bottom plate 17, and both are made of the same material. In other examples, the connection portion 170 and its attachment may be of different materials of construction, for example the same connection portion 170 may be provided on the metal chassis 17 or the keyboard circuit board 13 by insert-molding or hot-melting. In other embodiments, the two brackets of the bracket mechanism 20 may also constitute a V-shaped (butterfly-shaped) or inverted V-shaped (bat-shaped) architecture. In other embodiments, the first restoring member 112 may comprise a horizontal spring between two legs of the V-shape or inverted V-shape of the leg mechanism 20, or the first restoring member 112 may comprise a pair of magnetic members that attract or repel each other, also providing the restoring force. Furthermore, the first triggering member 113 is a downwardly extending protruding structure, and may be integrally formed at the bottom of the first restoring member 112, or the downwardly protruding first triggering member 113 is selectively disposed on the bottom surface of the first key cap 111 (as shown in fig. 1 to 4) or on the bottom surface of any one of the supports (not shown) of the support mechanism 20.
The second key 12 includes a second key cap 121, a second reset element 122 and a second trigger element 123. In addition to the second keycap 121, as shown in fig. 5, another set of second keycap 121' and second trigger (not shown) may be disposed on the device upper shell 31, and another second reset (not shown) and another portion of the proximity sensor, the keyboard circuit board 13 and the second trigger circuit 132 mentioned above (another set) on the keyboard 1 extend to below the second keycap 121', so as to form another operable second key 12 '. The second key cap 121/121 'and the second trigger 123 are part of the device upper shell 31, for example, in fig. 1 to 5, at least a part of the periphery of the second key cap 121/121' is integrally fixed to the device upper shell 31. One of the realization modes is as follows: a single groove 310 (fig. 1/3/4) or a plurality of grooves 310 (fig. 2) (upper and lower surfaces may be separated and not overlapped with each other; or both upper and lower surfaces may be provided on the surface (upper and/or lower surface) of the device upper shell 31 outside the through-hole array 35 around the periphery of the second key cap 121/121', so that the device upper shell 31 (i.e. the periphery of the second key cap 121/121') at the groove 310 has a smaller thickness and structural strength, and the second key cap 121 defined by the groove 310 can have a certain upper and lower deformation margin. The second restoring member 122 is, for example, a rubber cylinder, a non-metal spring (made of materials such as polyurethane, rubber, plastic, carbon fiber, etc.), other non-conductive elastic bodies, or a combination thereof (for example, the rubber cylinder is sleeved outside the tower-shaped non-metal spring), and is used for supporting the second key cap 121 when the second key cap 121 moves toward or away from the keyboard circuit board 13, and buffering and absorbing a portion of the pressing force, so as to prevent the second key cap 121 on the device upper housing 31 from being broken at the groove 310 and prolong the operating life thereof. In the embodiment shown in fig. 1 to 3, the second triggering element 123 is a second sensing layer disposed on the bottom surface of the second key cap 121, and the second sensing layer is made of a second sensing material corresponding to the proximity sensor 134, such as a second conductive material or a second ferromagnetic material. The second triggering member 123 is disposed between the second key cap 121 and the second resetting member 122, but not limited thereto, in other embodiments, the second triggering member 123 may also be disposed on the top surface of the second key cap 121 (as shown in fig. 4). In various embodiments, device housing 31 and second keycap 121/121' can be formed of a first inductive material, such as a first conductive material or a first ferromagnetic material that can be the same or different than a second inductive material. In other words, the second trigger member 123 and the device top case 31 and the second key cap 121/121' may be the same uniform sensing material or different sensing materials. If necessary, a support mechanism 20 may be disposed between the second key cap 121/121' and the bottom plate 17 (connected to the connecting portion 170) to balance the second key cap 121/121' during the pressing and descending process and provide more supporting force to prevent the second key cap 121/121' from breaking and deforming, but it is not absolutely necessary to implement the present invention.
In the present embodiment, the second key 12 is, for example, each key (e.g., ESC key, F1 key, etc.) in the function keypad of the keyboard 1, or a power key on the keyboard 1. Furthermore, leather or fabric may be disposed above the first key cap 111 or the second key cap 121 to improve the aesthetic feeling and the operation touch feeling.
When the first key 11 is operated, the first key cap 111 is moved downwards by performing a first pressing action on the first key cap 111, so that the first reset member 112 is deformed by moving from the high position to the low position in a direction approaching the keyboard circuit board 13, and the first trigger member 113 presses the switch pad 133 located therebelow along with the first key cap 111 moving downwards synchronously, so as to generate a keyboard input signal (for example, a signal including an alphanumeric/symbolic character, a text editing instruction, a function key, or a combination key instruction on a keyboard) in the first trigger circuit 131 by making the first trigger member 113 physically contact with the switch pad 133, thereby executing an instruction operation of the first key 11. When the operation of the first key 11 is released, that is, the first pressing action is released, the deformed first resetting member 112 provides a restoring force upwards (i.e., in a direction away from the keyboard circuit board 13) to reset the first key cap 111 (i.e., the first key cap 111 moves from the low position to the high position).
Furthermore, when the second key 12 is operated, the second key cap 121 can be moved downward by performing a second pressing action on the second key cap 121, and the second trigger 123 disposed on the top surface or the bottom surface of the second key cap 121 moves toward the proximity sensor 134 along with the movement of the second key cap 121, so that the relative position between the second trigger 123 and the proximity sensor 134 changes, and further the capacitance, the resistance, the magnetic flux or other induction quantity between the two changes, and in this state, the second reset 122 is compressed and deformed by the downward movement of the second key cap 121. Furthermore, when the proximity sensor 134 senses that the capacitance, resistance, magnetic flux or other sensing quantity changes to reach a certain sensing quantity threshold difference, the second trigger circuit 132 generates a device function signal to execute the command operation of the second button 12. When the second button 12 is released, i.e. the second pressing action is released, the deformed second reset element 122 provides an upward restoring force to reset the second key cap 121. In addition, in the present application, the whole circle of the sidewall of the second reset element 122 can provide an upward restoring force (feedback force), which not only can improve the sectional feeling of the second button 12, but also can shorten the stroke of the second button 12 to increase the operation feeling of the user. In a multi-sensor application, the second key cap 121/121' and the device housing 31 may be made of a first sensing material, and the (first) proximity sensor senses the pressing thereof to trigger a first signal, and the second triggering member 123 may be made of a second sensing material different from the first sensing material, and the (second) proximity sensor senses the pressing thereof to trigger a second signal, for example, the two sets a specific sensing threshold difference, so that the second key cap 121/121' can trigger different functions of the electronic device 3 at different pressing force/pressing displacement distances, and the second key cap 121/121' can be single-bonded to provide functions such as power-on, keyboard backlight-on, sleep-on, and reboot …. For example, when the second key cap 121 is pressed to move to the first key stroke, the power supply is started when the (first) proximity sensor (e.g., a capacitance sensor) senses that the second key cap 121 is pressed to the first key stroke (reaching the capacitance change threshold difference); when the second key cap 121 is pressed to move to the second key stroke, the (second) proximity sensor (e.g., magnetic sensor) senses that the second key cap 121 is pressed to the second key stroke (reaching the magnetic flux change threshold difference), and the power supply is turned on. In a multi-sensor application, another second trigger circuit may also be required for another sensor.
In other embodiments, the keyboard 1 of the present application may be designed as a light-emitting keyboard, and specifically, as shown in fig. 2 to 4, the first key 11 further has a first transparent region 114, and the second key 12 also has a second transparent region 124. In the present application, the first transparent region 114 and the second transparent region 124 are, for example, micro-perforations formed on the first key cap 111 and the second key cap 121.
Meanwhile, the keyboard 1 is further provided with a light emitting module 16, and can generate light passing through the first transparent area 114 and the second transparent area 124, so that the first keycap 111 and the second keycap 121 emit light. In the present application, the light emitting module 16 is, for example, an LED lamp.
In addition, a second through hole 1231 is formed at a position of the second trigger 123 disposed on the second key cap 121 corresponding to the second light-transmitting region 124, and the second through hole 1231 can allow light generated by the light-emitting module 16 to pass through.
In the embodiment of the present application, the light emitting module 16 may be disposed above the keyboard circuit board 13 (fig. 2), but not limited thereto, in the embodiment shown in fig. 3 and fig. 4, the light emitting module 16 is disposed below the keyboard circuit board 13, wherein a through hole 135 is further formed at a position of the keyboard circuit board 13 corresponding to the second light-transmitting region 124, and light provided by the light emitting module 16 located below the keyboard circuit board 13 can sequentially pass through the keyboard circuit board 13 and the second light-transmitting region 124 through the through hole 135 to enable the second key 12 to emit light. In addition, a through hole 135 may be formed in the keyboard circuit board 13 corresponding to the first transparent region 114, so that the light provided by the light emitting module 16 sequentially passes through the keyboard circuit board 13 and the first transparent region 114 to make the first key 12 emit light.
