Description

TECHNICAL FIELD

[0001] The present invention relates to a keyboard and a key structure capable of displaying real-time images, in particular to a keyboard and a key structure capable of displaying real-time images, in which an elastic member is arranged at one side of a key cap, so that a display unit at the bottom can present images upward through the key to a user. BACKGROUND

[0002] The scissors structure of the prior art keyboard has two cross-shaped support frames, in which the top end of one support frame is pivotally connected to the bottom of the key cap, and the bottom end is slidably arranged on the bottom plate. The top end of the other support frame is slidably arranged on the bottom of the key cap, and the bottom end is pivotally connected to the bottom plate. In addition, the two support frames are also pivotally connected to each other at the intersection. The "pivotally connected" above means that only rotation is allowed and movement relative to the key cap is not allowed. In addition, the elastic member is arranged in the middle of the key cap.

[0003] The key structure above cannot make light or images pass upward from the bottom to the top surface of the key cap. In addition, because the intersection of the two support frames is pivotally connected to each other, the linkage between the support frames is limited. In particular, when the user applies force to a corner of the key cap, the key cap is easily deflected, and the key cap cannot be smoothly lowered, affecting the user's operation touch.

[0004] In order to provide a key with the function of emitting light or displaying images, the elastic member is arranged at one side of the key cap, and the key cap is made of light-transmitting material. However, because the elastic force of the elastic member acts on one side of the key cap when the user applies force to the key cap, in combination with the existing scissors structure, the key cap may be unevenly stressed and deflected. In addition, each support frame of the existing scissors structure is annular, and the bottom of the support frame blocks some light or images.

[0005] Therefore, how to improve the key structure capable of displaying real-time images through structural design to overcome the above-mentioned defects has become a problem to be solved in this technical field. SUMMARY

[0006] The technical problem to be solved by the present invention is to provide a key structure capable of displaying real-time images to solve the problem of uneven stress and deflection of the key cap, so that the key cap can be smoothly lowered in the pressing stroke.

[0007] To solve the above technical problems, one of the technical solutions adopted by the present application is to provide a key structure capable of displaying real-time images, which comprises a display unit, a key seat arranged above the display unit, a first support frame, a second support frame and a light-transmitting key cap. The key seat forms a hollow accommodating portion. The first support frame has two first arm portions and two shaft portions, each first arm portion forms a shaft portion, and the bottom ends of the two first arm portions are rotatably connected in the accommodating portion. The second support frame has two second arm portions and two connecting holes, the second support frame intersects with the first support frame, each second arm portion of the second support frame forms a connecting hole, and the bottom ends of the two second arm portions are slidably arranged in the accommodating portion; wherein the connecting hole is long and narrow, the two shaft portions of the two first arm portions are slidably located in the two connecting holes of the two second arm portions, and the width of the connecting hole along the longitudinal direction of the second arm portion is greater than the height perpendicular to the longitudinal direction of the second arm portion. The top end of the first support frame and the top end of the second support frame are slidably connected to the two sides of the light-transmitting key cap, respectively; wherein the image of the display unit passes through the accommodating portion and is transmitted outward through the light-transmitting key cap. When the light-transmitting key cap is in an unpressed state, the shaft portion of the first arm portion abuts against one hole end of the connecting hole; when the light-transmitting key cap is in a pressed state, the shaft portion of the first arm portion abuts against the other hole end of the connecting hole.

[0008] According to an embodiment of the present application, the key structure capable of displaying real-time images further comprises a circuit film arranged above the display unit and an elastic member arranged on the circuit film, the elastic member being close to one side of the accommodating portion; one side of the light-transmitting key cap is provided with a pressing protrusion corresponding to the elastic member, the circuit film has a conducting portion, and the elastic member abuts against the conducting portion.

[0009] According to an embodiment of the present application, the accommodating portion of the key seat has a front side, a back side and two opposite side sides, the back side forms a conducting groove, the elastic member is arranged in the conducting groove, the bottom of the front side forms a limiting groove and a stop flange located above the limiting groove, and the other side of the light-transmitting key cap has a limiting protrusion extending outward in the opposite direction of the pressing protrusion, the limiting protrusion is movably located in the limiting groove.

[0010] According to an embodiment of the present application, the accommodating portion has two sliding protrusions protruding inward from the two side sides, respectively, and the bottom ends of the two first arm portions of the first support frame are slidably arranged in the two sliding protrusions, respectively.

[0011] According to an embodiment of the present application, the first support frame has a first horizontal rod, the two first arm portions are connected to the two sides of the first horizontal rod, respectively, the first side of the light-transmitting key cap forms a first side groove located above the pressing protrusion, and the first horizontal rod is arranged in the first side groove.

[0012] According to an embodiment of the present application, the accommodating portion has two pivot members respectively located at two sides, each pivot member forms an upward connecting hole, and the bottom end of each second arm of the second support frame has a pivot rod rotatably connected to the connecting hole.

[0013] According to an embodiment of the present application, the accommodating portion has two grooves respectively formed at two sides, and the two pivot members are respectively arranged in the two grooves.

[0014] According to an embodiment of the present application, the second support frame has a second horizontal rod, and the two second arms are respectively connected to two sides of the second horizontal rod. The second side of the light-transmitting keycap opposite to the first side forms a second side groove, and the second horizontal rod is arranged in the second side groove.

[0015] According to an embodiment of the present application, the front side and the rear side of the accommodating portion each has at least one stopper. When the light-transmitting keycap is in the pressed state, the at least one stopper stops the first support frame and the second support frame.

[0016] To solve the above technical problems, another technical scheme of the present application provides a keyboard comprising at least one key structure capable of displaying real-time images. The key structure capable of displaying real-time images comprises a display unit, a key seat arranged above the display unit, a first support frame, a second support frame, and a light-transmitting keycap. The key seat forms a hollow accommodating portion. The first support frame has two first arms and two shafts, each first arm forms a shaft, and the bottom end of each first arm is rotatably connected to the accommodating portion. The second support frame has two second arms and two connecting holes, the second support frame crosses the first support frame, each second arm of the second support frame forms a connecting hole, and the bottom end of each second arm is slidably arranged in the accommodating portion. The connecting hole is long and narrow, the two shafts of the two first arms are slidably arranged in the two connecting holes of the two second arms, the width of the connecting hole along the longitudinal direction of the second arm is greater than the height of the connecting hole perpendicular to the longitudinal direction of the second arm. The top end of the first support frame and the top end of the second support frame are slidably connected to two sides of the light-transmitting keycap. The image of the display unit is transmitted through the accommodating portion and the light-transmitting keycap to the outside. When the light-transmitting keycap is in the unpressed state, the shaft of the first arm abuts against one hole end of the connecting hole, and when the light-transmitting keycap is in the pressed state, the shaft of the first arm abuts against the other hole end of the connecting hole.

[0017] One of the beneficial effects of this invention is that the key structure capable of displaying real-time images, through "the top ends of the first support frame and the top ends of the second support frame being slidably connected to both sides of the backlit keycap," prevents the backlit keycap from tilting due to rotation. Furthermore, "the connecting holes are elongated, and the two shaft portions of the two first arms are slidably located in the two connecting holes of the two second arms; the width of the connecting holes along the longitudinal direction of the second arms is greater than the height perpendicular to the longitudinal direction of the second arms." During the downward stroke of the backlit keycap, the elongated connecting holes allow the first arms to smoothly slide laterally and gradually lower, thereby stably supporting the downward stroke of the backlit keycap. This provides the user with a stable and non-tilting pressing feel.

[0027] See Figures 1-2The present application provides a keyboard 1, which comprises a plurality of key structures 100 capable of displaying real-time images. The keyboard 1 comprises a display unit 11, an additional circuit board 13, a circuit membrane 14, a plurality of elastic members 20, a key base 30, a plurality of supporting units 50, a plurality of light-transmitting key caps 60, and a cover plate 70. The display unit 11 can be a liquid crystal display screen. The additional circuit board 13 forms a plurality of first through holes 130. The circuit membrane 14 is disposed above the display unit 11. The circuit membrane 14 has a plurality of membrane through holes 140 and a plurality of conductive portions 142. The conductive portions 142 protrude inwardly from an edge of the membrane through holes 140. The membrane through holes 140 correspond in shape to the first through holes 130. Image information of the display unit 11 can pass through the first through holes 130, the membrane through holes 140, and the key base 30 and be transmitted outwardly through the light-transmitting key caps 60. However, the present application is not limited thereto, and the circuit membrane 14 can also omit the membrane through holes 140, for example, the uppermost layer is transparent and has no through holes, one side can prevent dust, and the other side can still transmit image information of the display unit 11 upwardly.

[0028] Referring to Figure 3 and Figure 4 The plurality of elastic members 20 are respectively disposed on the plurality of conductive portions 142. When the light-transmitting key caps 60 are pressed, the circuit of the conductive portions 142 is pressed by the elastic members 20 to provide a conductive signal. The plurality of elastic members 20 can be separate components or integrally formed in a one-piece structure, and the shape of the one-piece structure can correspond to the shape of the circuit membrane 14. The elastic members of the present embodiment can be rubber domes, which provide elastic force to return the key caps to the original position and conduct the conductive portions 142 of the circuit membrane 14 downwardly. However, the present application is not limited thereto, and the elastic members can be other components capable of returning the key caps to the original position, such as springs, metal springs, and the like. In addition, the present application is not limited to using the elastic members to conduct the signal, and the present application can also conduct the conductive portions 142 of the circuit membrane 14 by a protruding portion of the key cap downwardly. The additional circuit board 13 is screwed upwardly and positioned with the circuit membrane 14 and the key base 30 from the bottom by screws S (see Figure 5 ) to provide support force. However, the present application is not limited to the above-mentioned conductive mode, and for example, the elastic members 20 can directly press the surface of the display unit 11 to form a conductive state.

[0029] The following is described with respect to a single key structure 100. The key structure 100 includes a display unit 11, a circuit film 14 disposed above the display unit 11, an elastic member 20 disposed on the circuit film 14, a key seat 30 disposed on the circuit film 14, a support unit 50, and a light-transmissive key cap 60. The key seat 30 forms a hollow accommodating portion 31 through which an image of the display unit 11 passes, and the elastic member 20 is close to one side of the accommodating portion 31. The support unit 50 has a first support frame 51 and a second support frame 52.

[0030] The first support frame 51 and the second support frame 52 of the present embodiment are substantially U-shaped. The first support frame 51 is assembled crosswise on the second support frame 52. The bottom of the U-shape does not block the image of the display unit 11. Specifically, the first support frame 51 has a first horizontal bar 511, two first arm portions 513, and two shaft portions 515. The two first arm portions 513 are connected to the two sides of the first horizontal bar 511, respectively. Each of the first arm portions 513 forms a shaft portion 515, and the bottom ends 5132 of the two first arm portions 513 are rotatably connected in the accommodating portion 31. The second support frame 52 has a second horizontal bar 521, two second arm portions 523, and two connecting holes 525. The two second arm portions 523 are connected to the two sides of the second horizontal bar 521, respectively. Each of the second arm portions 523 forms a connecting hole 525. The bottom ends of the two second arm portions 523 are disposed in the accommodating portion 31 in a manner of fixed-point rotation, or in other words, are pivotally connected to the two sides of the accommodating portion 31, respectively. The first support frame 51 and the second support frame 52 of the present embodiment can be metal pieces formed by stamping. The shaft portions 515 can be another component connected to the first arm portions 513. However, the present application is not limited thereto, and the first support frame 51 as a whole can also be a component integrally formed. That is, the shaft portions 515 can be integrally formed with the first support frame 51. For example, the first support frame 51 and the shaft portions 515 can be metal pieces formed by stamping, and the shaft portions 515 protrude outward from the first arm portions 513 by local stamping; or, for example, the first support frame 51 and the second support frame 52 can be formed by plastic injection molding.

[0031] One feature of the present embodiment is that the connecting holes 525 are elongated, and the two shaft portions 515 of the two first arm portions 513 are slidably located in the two connecting holes 525 of the two second arm portions 523, respectively. As shown in Figure 5 more specifically, the connecting holes 525 are capsule-shaped or oval-shaped, and the width W along the longitudinal direction of the second arm portions 523 of the connecting holes 525 is greater than the height H perpendicular to the longitudinal direction of the second arm portions 523.

[0032] The light-transmissive key cap 60 is made of a light-transmissive material, the top end of the first support frame 51 and the top end of the second support frame 52 are slidably connected to the two sides of the light-transmissive key cap 60, respectively, and the light-transmissive key cap 60 is provided with a pressing protrusion 61 (see FIG. 2).Figure 4 and Figure 6 The pressing protrusion 61 corresponds to the elastic member 20.

[0033] As shown in Figure 5 , when the light-transmitting keycap 60 is in the unpressed state, the shaft portion 515 of the first arm portion 513 abuts against one hole end 5251 (or the initial hole end) of the connecting hole 525. As shown in Figure 7 , when the light-transmitting keycap 60 is in the pressed state, the shaft portion 515 of the first arm portion 513 abuts against the other hole end 5252 (or the terminal hole end) of the connecting hole 525. Specifically, the longitudinal direction of the connecting hole 525 is not parallel to the longitudinal direction of the second arm portion 523, and the longitudinal direction of the connecting hole 525 is slightly parallel to the bottom surface, or the horizontal surface, of the key seat 30. During the pressing of the light-transmitting keycap 60, the connecting hole 525 moves along the hole end 5251 as the center, and the other hole end 5252 is slightly higher than the hole end 5251, and moves to be slightly lower than the hole end 5251. In other words, during the pressing of the light-transmitting keycap 60 of the present embodiment, the shaft portion 515 can be guided by the elongated connecting hole 525 at all times, and the light-transmitting keycap 60 will not be deflected along the first support frame 51 or the second support frame 52, so that the downward pressing stroke of the light-transmitting keycap 60 can be smooth and not deflected, to provide a better pressing touch for the user. More details are described below.

[0034] As shown in Figure 3 and Figure 4 , the accommodating portion 31 of the key seat 30 has a front side 311, a rear side 312, and two opposite side sides 313. The rear side 312 forms a through groove 3120, and the elastic member 20 is arranged in the through groove 3120. The bottom of the front side 311 forms a limiting groove 3110, and a stop flange 3112 is formed above the limiting groove 3110. The other side of the light-transmitting keycap 60 has a limiting protrusion 62 extending outwardly in the opposite direction of the pressing protrusion 61 (see Figure 3 ). Specifically, the light-transmitting keycap 60 has opposite first and second sides 601 and 602. The bottom of the first side 601 extends downwardly and outwardly to form the pressing protrusion 61, and the bottom of the second side 602 extends downwardly and outwardly to form the limiting protrusion 62. The limiting protrusion 62 is movably arranged in the limiting groove 3110. As shown in Figure 6 , when the light-transmitting keycap 60 is in the unpressed state, the cover plate 70 stops the pressing protrusion 61 of the light-transmitting keycap 60, and the stop flange 3112 stops the limiting protrusion 62, to limit the light-transmitting keycap 60 to be in the unpressed state.

[0035] Referring to Figure 6 and Figure 8The first side 601 of the light-transmitting key cap 60 is formed with a first side recess 612 above the pressing protrusion 61, and the first horizontal rod 511 is arranged in the first side recess 612. The second side 602 of the light-transmitting key cap 60 opposite to the first side 601 is formed with a second side recess 622 above the limiting protrusion 62, and the second horizontal rod 521 is arranged in the second side recess 622.

[0036] Referring to Figure 3 and Figure 4 The support unit 50 is connected to the accommodating portion 31 as follows. The accommodating portion 31 has two sliding protrusions 35 protruding inwardly from the two sides 313, respectively. The bottom ends of the two first arm portions 513 of the first support frame 51 are slidably arranged in the two sliding protrusions 35, respectively. However, the present application is not limited thereto, and the sliding protrusions can be another plate arranged on the bottom of the key base 30.

[0037] The accommodating portion 31 has two pivot members 32 arranged on the two sides 313, respectively. Each pivot member 32 is formed with an upwardly-opening pivot hole 320. The bottom ends of the two second arm portions 523 of the second support frame 52 are each provided with a pivot rod 5232 rotatably connected to the pivot hole 320 of the pivot member 32. Specifically, the accommodating portion 31 has two rectangular recesses 3130 formed on the two sides 313, respectively. The two pivot members 32 are arranged in the two recesses 3130, respectively. In the present embodiment, the pivot members 32 can be formed in the recesses 3130 by plastic injection molding. However, the present application is not limited thereto, and the pivot members 32 can be integrally formed with the accommodating portion 31.

[0038] It is to be noted that Figure 4 and Figure 7 The front side 311 and the rear side 312 of the accommodating portion 31 are each provided with two stop blocks 36. When the light-transmitting key cap 60 is in the pressed state, the stop blocks 36 can stop the first support frame 51 and the second support frame 52.

[0039] [Advantages of the Embodiment]

[0040] Compared with the scissors structure of the known keyboard, the top end of one support frame of the scissors structure is pivoted to the bottom of the keycap, and the top end of the other support frame is slidably arranged on the bottom of the keycap. In addition, the two support frames are pivoted to each other. Wherein, the "pivoted" means that only rotation is limited and movement relative to the keycap is not limited. If this mode is applied to the key structure 100 capable of displaying real-time images of the present application, since the elastic member 20 is located on one side of the light-transmitting keycap 60, in the process of pressing the light-transmitting keycap 60 under force, the elastic member 20 forms an upward elastic force acting on one side of the light-transmitting keycap 60, which is easy to cause the keycap to rotate around the "pivoted" position as the fulcrum, and is easy to cause deflection and unevenness.

[0041] The key structure 100 capable of displaying real-time images of the present application avoids the deflection of the light-transmitting keycap 60 due to rotation by "the top end of the first support frame and the top end of the second support frame being slidably connected to the two sides of the light-transmitting keycap, respectively". In addition, "the connecting hole is long and narrow, the two shaft portions of the two first arm portions are slidably located in the two connecting holes of the two second arm portions, respectively; the width of the connecting hole along the longitudinal direction of the second arm portion is greater than the height perpendicular to the longitudinal direction of the second arm portion". When the light-transmitting keycap is pressed under force, the long and narrow connecting hole can provide smooth lateral sliding of the first arm portion and gradually reduce, so as to smoothly support the pressing stroke of the light-transmitting keycap. Thus, the user can have a smooth and non-deflection pressing touch.

[0042] The above is only the preferred and feasible embodiment of the present application, and any equivalent changes and modifications made according to the claims of the present application shall be within the scope of the present application.
