DETAILED DESCRIPTION
Referring to FIGS. 1-2, an electronic device 1 according to an exemplary embodiment is disclosed. The electronic device 1 includes a main body 10 and a lid 20 rotatably connected to the main body 10. The main body 10 includes a lower housing 11, an upper housing 12, a keyboard 13, a driving mechanism 14 (see FIG. 4), and a cover 15. The keyboard 13 and the cover 15 are both disposed on the upper housing 12. The driving mechanism 14 is received between the lower housing 11 and the upper housing 12.
FIG. 1 shows the main body 10 in a first state that part of the first keyboard 130 is shielded by the cover 15. FIG. 2 shows the main body 10 in a second state that the first keyboard 130 and the second keyboard 132 is moved to be totally exposed as driven by the driving mechanism 14.
Referring to FIGS. 3-4, the lower housing 11 and the upper housing 12 are both rectangular and coupled to each other. Electronic components, e.g., a central processing unit (CPU), a printed circuit board (PCB), and a fan, can be received between the lower housing 11 and the upper housing 12. The upper housing 12 includes a bottom surface 121 and an opposite top surface 122. The upper housing 12 defines two first slots 123 and two second slots 124 spanning through from the bottom surface 121 to the top surface 122. Each first slot 123 is L shaped and includes a first end 1231, a second end 1232, and a transition 1233 between the first end 1231 and the second end 1232. Each second slot 124 is substantially straight and includes a third end 1241 and a fourth end 1242. The upper housing 12 includes a bar 125 on an edge of the top surface 122 to prevent the keyboard 13 from disengaging from the main body, and a guide block 126 and a guide plate 127 on the bottom surface 121. The guide block 126 and the guide plate 127 both extend parallel to the second slots 124. The guide block 126 includes a first guide edge 1260 and an opposite guide edge 1262. The guide plate 127 includes a third guide edge 1270 facing toward the second guide edge 1262.
The keyboard 13 includes a first keyboard 130 and a second keyboard 132 coupled to each other. In the embodiment, the edges of the first keyboard and the second keyboard to connect each other are both step shaped.
Referring also to FIG. 5, the driving mechanism 14 includes a first mechanism 14a and a second mechanism 14b. The first mechanism 14a is connected to the first keyboard 130 through the first slots 123, and the second mechanism 14b is connected to the second keyboard 132 through the second slots 124.
The first mechanism 14a includes a motor 141, a first gear 142, a first driving member 143, and a first slider 144. The motor 141 is disposed on the bottom surface 121 of the upper housing 12. The first gear 142 is connected to a motor shaft (not shown) of the motor 141 and can rotate together with the motor shaft.
The first driving member 143 is elongated shaped and includes a first end 1430 and an opposite second end 1432. One side of the first end 1430 also includes a first rack 1434 for engaging the first gear 142, which converts the rotation of the first gear 142 into sliding movement of the first driving member 143. The opposite side stays in contact with the first guide edge 1260 of the upper housing 12, such that the first driving member 143 can slide along the first guide edge 1260. The second end 1432 defines a first guide slot 1436.
The first slider 144 includes a first portion 1441 and a second portion 1442 connected to each other. The second portion 1442 includes a guide bar 1443 and defines a second guide slot 1444. The guide bar 1443 slopes to the first portion 1441. The guide bar 1443 is slidably connected to the first guide slot 1436 of the first driving member 143. The second guide slot 1444 extends substantially perpendicular to the first portion 1441. The first slider 144 is fastened to the first keyboard 130 by screws (not labeled) passing through the first slots 123. The first slider 144 and the first keyboard 130 can slide together along the first slots 123.
The second mechanism 14b includes a second gear 145, a second driving member 146, and a second slider 147. The second gear 145 engages the second driving member 146 and the second slider 147 to transmit the sliding movement from the first slider 144 to the second slider 147.
The second driving member 146 is elongated shaped and includes a third end 1460 and an opposite fourth end 1462. One side of the third end 1460 includes a second rack 1464, which engages the second gear 145, and an opposite side stays in contact with the second guide edge 1262 of the guide block 126, such that the second driving member 146 can slide along the second guide edge 1262. The second end 1462 includes a protrusion 1466 slidably received in the second guide slot 1444 of the first slider 144.
The second slider 147 includes a third portion 1470 and a fourth portion 1472 connected to each other. The third portion 1470 is fastened to the second keyboard 132 by screws (not labeled) passing through the second slots 124. One side of the fourth portion 1472 includes a third rack 1474, and an opposite side stays in contact with the third guide edge 1270 of the guide plate 127, such that the second slider 147 can slide along the third guide edge 1270.
Referring again to FIGS. 1 and 5, the first slider 144 is fastened to the first keyboard 130 by screws passing though the first end 1231 of the first slot 123, and the second keyboard 132 is fastened to the second slider 147 by screws passing though the third end 1241 of the second slot 124. As shown in FIG. 1, in the first state, part of the keyboard 13 is shielded by the cover 15.
Referring also to FIGS. 6 and 7, when the motor 141 rotates the first gear 142, the first slider 143 slides along the first guide edge 1260 of the guide block 126. First, the first slider 144 will slide from the first end 1231 to the transition 1233 of the first slot 123 and the second slider 147 slides from the third end 1241 to the fourth end 1242 of the second slot 124, as driven by the second driving member 146. Secondly, the first guide slot 1436 of the first driving member 143 slides along the guide bar 1443 of the first slider 144 causing the first slider 144 to slide from the transition 1233 to the second end 1232 of the first slot 123. Thus, the main body 10 is switched to the second state.
Referring to FIGS. 2 and 8, in the second state, the first slider 144 is fastened to the first keyboard 130 by screws passing though the second end 1232 of the first slot 123, and the second keyboard 132 is fastened to the second slider 147 by screws passing though the fourth end 1242 of the second slot 124. As shown in FIG. 2, in the second state, the keyboard 13 is totally exposed.
Finally, while the present disclosure has been described with reference to particular embodiments, the description is illustrative of the disclosure and is not to be construed as limiting the disclosure. Therefore, various modifications can be made to the embodiments by those of ordinary skill in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
