Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.
Fig. 1A is a schematic view of an electronic device in an unfolded state according to an embodiment of the invention. Fig. 1B is a partial cross-sectional schematic view of the electronic device of fig. 1A. Fig. 2A is a schematic view of an electronic device in a closed state according to an embodiment of the invention. Fig. 2B is a partial cross-sectional schematic view of the electronic device of fig. 2A. Referring to fig. 1A and fig. 2A, in the present embodiment, the electronic device 100 may be a notebook computer, and includes a host 110 and a display 120. The display 120 is pivotally connected to the host 110, and is configured to be unfolded relative to the host 110, or to be covered on the host 110.
Referring to fig. 1A, fig. 1B and fig. 2B, the electronic device 100 further includes a sliding plate 130 and a keyboard 140, wherein the sliding plate 130 is slidably disposed in the host 110, and the display 120 is mechanically coupled to the sliding plate 130. In the process of opening and closing the display 120 relative to the main frame 110, the sliding plate 130 is driven by the display 120 to slide along a specific direction to and fro relative to the main frame 110. The keyboard 140 is integrated with the host 110, wherein the keyboard 140 includes a plurality of key structures 140 a.
Specifically, the key structure 140a includes a key cap 141 and a reciprocating member 142, wherein the main body 110 has an operation surface 111, and the key cap 141 is exposed on the operation surface 111 for a user to operate the key structure 140 a. The reciprocating member 142 is disposed between the key cap 141 and the sliding plate 130, and is used for supporting the key cap 141 and providing a restoring force to the key cap 141. Further, the reciprocating member 142 may include a first end 142a and a second end 142b, the first end 142a is connected to the key cap 141, and the second end 142b contacts the sliding plate 130.
For example, the reciprocating member 142 may comprise a spring and a telescopic cover, and the spring is disposed in the telescopic cover, wherein one end of the telescopic cover is connected to the key cap 141, and the other end of the telescopic cover contacts the sliding plate 130. On the other hand, one end of the spring contacts the key cap 141, and the other end of the spring contacts the bottom of the telescopic cover.
In the present embodiment, the sliding plate 130 includes a platform portion 131 and a plurality of recessed portions 132 arranged in parallel, wherein the number of the recessed portions 132 may be a plurality, and the number of the recessed portions 132 is equal to the number of the key structures 140 a. In detail, the reciprocating member 142 is located on the sliding path between the platform portion 131 and the recess portion 132, as shown in fig. 1B, when the display 120 is unfolded relative to the host 110, the reciprocating member 142 contacts the platform portion 131, and the key cap 141 is higher than the operating surface 111, so that a sufficient pressing stroke can be provided for a user to improve the operating experience of the user.
As shown in fig. 2B, when the display 120 covers the operation surface 111 of the host 110, the sliding plate 130 slides, so that the second end 142B of the reciprocating member 142 moves away from the platform 131 and moves into the recess 132. Meanwhile, the key cap 141 sinks along with the reciprocating member 142, so that the key cap 141 is lower than the operation surface 111, and the pressing of the key structure 140a by the display 120 covering the operation surface 111 of the main frame 110 can be avoided, thereby prolonging the service life of the product.
Specifically, the key cap 141 is perpendicular to the sliding direction of the sliding plate 130 along with the sinking direction of the reciprocating member 142.
Referring to fig. 1A and fig. 1B, in the present embodiment, the electronic device 100 further includes a rotating shaft 150, and the display 120 is pivotally connected to the host 110 through the rotating shaft 150. In detail, the hinge 150 includes a driving portion 151 located in the main unit 110, and the driving portion 151 is mechanically coupled to the sliding plate 130. On the other hand, the sliding plate 130 further includes a driven portion 133 adjacent to the rotation shaft 150, and the driving portion 151 is mechanically coupled to the driven portion 133. For example, the driving part 151 is a gear, and the driven part 133 is a rack that engages with the gear 151. In the process of opening and closing the display 120 relative to the main frame 110, the driving part 151 rotates relative to the main frame 110 and drives the rack, so that the sliding plate 130 slides.
Referring to fig. 1B and fig. 2B, the recessed portion 132 has a slope 132a and a bottom surface 132B connected to the slope 132a, and the slope 132a is connected to the platform portion 131. When the sliding plate 130 slides, the second end 142b of the reciprocating member 142 moves from the platform 131 through the inclined surface 132a and stops moving after contacting the bottom surface 132 b. Alternatively, when the sliding plate 130 slides, the second end 142b of the reciprocating member 142 moves from the bottom surface 132b through the inclined surface 132a and stops moving after contacting the platform 131.
Because there is a height difference between the terrace portion 131 and the bottom surface 132b of the recess 132, the height of the key cap 141 changes as the second end 142b of the reciprocating member 142 contacts the terrace portion 131 or the bottom surface 132b of the recess 132. On the other hand, the platform portion 131 is parallel to the bottom surface 132b of the recess portion 132, so as to avoid the situation that the keycap 141 and the reciprocating member 142 are deflected.
In this embodiment, the keyboard 140 further includes a carrier 143 fixed in the main body 110, and the carrier 143 is disposed on the sliding plate 130. That is, during the opening and closing process of the display 120 relative to the main unit 110, the carriage 143 is fixed, but the sliding plate 130 slides relative to the carriage 143. On the other hand, the key cap 141 is disposed above the carriage 143, wherein the carriage 143 has a through hole 143a, and the second end 142b of the reciprocating member 142 passes through the through hole 143a to contact the sliding plate 130. The number of the through holes 143a of the carrier 143 is equal to the number of the key structures 140 a.
The key structure 140a further includes a scissor mechanism 144, and the scissor mechanism 144 is disposed between the key cap 141 and the carrier 143 for stabilizing the moving direction of the key cap 141 when the key cap 141 is pressed by a force or the moving direction of the key cap 141 when the key cap 141 is reset. On the other hand, both ends of the scissor mechanism 144 contact the key cap 141 and the carriage 143, respectively, and the movement direction of the key cap 141 is perpendicular to the sliding direction of the slide plate 130 based on the guidance of the scissor mechanism 144.
In summary, in the electronic device of the present invention, the height of the key cap of the key structure changes with the opening and closing of the display relative to the host. Furthermore, when the display is unfolded relative to the host, the keycap of the key structure is higher than the operation surface of the host, so that a sufficient pressing stroke can be provided for a user, and the operation experience of the user is improved. On the contrary, when the display covers the operation surface of the host, the keycap of the key structure is lower than the operation surface of the host, so that the key structure can be prevented from being extruded by the display covering the operation surface of the host, and the service life of the product is prolonged.
