DESCRIPTION OF THE EMBODIMENTS
FIG. 1A is a schematic diagram of an electronic apparatus according to an embodiment of the invention, FIG. 1B is a cross-sectional diagram of the electronic apparatus of FIG. 1A along line I-I and FIG. 2A is a cross-sectional diagram of the electronic apparatus of FIG. 1B in a folded state. Referring to FIGS. 1A-2A, an electronic apparatus 100 of the embodiment includes a first body 110, a second body 120 and a keyboard 130. The first body 110 has a display surface 112 and an appearance surface 114 opposite to the display surface 112. The second body 120 is pivoted to the first body 110 and has an accommodating opening E and a first surface 122 and a second surface 124 opposite to the first surface 122. When the first body 110 is closed to the second body 120, the first surface 122 faces the display surface 112. The keyboard 130 uses at least one rotation-shaft 140 to be pivoted at the accommodating opening E. In the embodiment, there are two rotation-shafts 140 in total respectively disposed at both opposite sides of the keyboard 130. FIG. 2B is a cross-sectional diagram of the electronic apparatus of FIG. 1B in another folded state. Referring to FIGS. 1B and 2B again, when the first body 110 is unfolded from the second body 120 and turned over, the keyboard 130 is able to be turned over relatively to the second body 120 to make the first body 110 cover a plurality of keys 133 of the keyboard 130 when the second surface 124 faces the appearance surface 114 (as shown in FIG. 2B).
In more details, in the embodiment, the keyboard 130 has a first side-wall 134 and a second side-wall 135 opposite to each other, and the first side-wall 134 and the second side-wall 135 are the two opposite side-walls 134 and 135 in the keyboard 130, wherein the side-walls 134 and 135 are not pivoted to the second body 120. In other words, when the keyboard 130 gets turned over relatively to the second body 120 around the axis of the rotation-shaft 140, the first side-wall 134 and the second side-wall 135 facing into the accommodating opening E would be altered along with the turning-over-angle of the keyboard 130. For example, in the second body 120, there are a first accommodating side-wall 126 and a second accommodating side-wall 128 opposite to each other and surrounding the accommodating opening E. When the first body 110 moves from the state of FIG. 1B to the state of FIG. 2A, the first surface 122 faces the display surface 112, and the first side-wall 134 and the second side-wall 135 respectively face the first accommodating side-wall 126 and the second accommodating side-wall 128; when the first body 110 moves from the state of FIG. 1B to the state of FIG. 2B, the keyboard 130 gets turned over relatively to the second body 120 so that the second surface 124 faces the appearance surface 114 and the first side-wall 134 and the second side-wall 135 respectively face the second accommodating side-wall 128 and the first accommodating side-wall 126. The invention does not limit the rotation direction of the keyboard 130.
In the embodiment, the first body 110 can be unfolded from the second body 120 and turned over to the back of the second body 120, and the keyboard 130 of the electronic apparatus 100 can be rotatively disposed in the accommodating opening E of the second body 120. The keyboard 130 can rotate relatively to the second body 120 through the rotation-shaft 140, so that the first body 110 in different folded states (as shown by FIGS. 2A and 2B) can cover the keyboard 130. In this way, the electronic apparatus 100 of the embodiment can avoid the keys 133 of the keyboard 130 from exposure to make the keys 133 scratched or fall off when the first body 110 is turned over to the back of the second body 120.
In addition, in the embodiment, the keyboard 130 can be turned over relatively to the second body 120, and accordingly, the accommodating opening E and the keyboard 130 are not closely matched entirely to each other. For example, both the first side-wall 134 and the second side-wall 135 of the keyboard 130 and both the first accommodating side-wall 126 and the second accommodating side-wall 128 in the accommodating opening E keep a gap D therebetween (as shown in FIG. 1A) to avoid the corners of the keyboard 130 and the second body 120 from interference therebetween when the keyboard 130 is turned over relatively to the second body 120. For keeping the appearance unaffected by an excessive gap D between the keyboard 130 and the accommodating opening E, both the first side-wall 134 and the second side-wall 135 are respectively an arc surface C1, and the arc surfaces C1 are surfaces which are convex respectively from the centers of the two side-walls 134 and 135 up and then gradually shrunk towards the upper side and the lower side of each of the side-walls 134 and 135 so as to decrease the gap D between the keyboard 130 and the accommodating opening E. In addition, the first accommodating side-wall 126 and the second accommodating side-wall 128 of the accommodating opening E facing the side-walls 134 and 135 can respectively be a dent C2, in which the arc surfaces C1 and the dents C2 are complementary to each other. However, the invention does not limit the shape of the side-wall. In other unshown embodiments, the upper and lower two sides can respectively be a chamfer, which functions also to avoid the corners of the keyboard and the second body from interference therebetween.
FIG. 3A is a schematic diagram of the electronic apparatus of FIG. 1A around a rotation-shaft thereof. Referring to FIGS. 1A, 1B and 3A, for better showing the structure around the rotation-shaft 140, the second body 120 is marked in hidden lines, and partial structures of the keyboard 130 and the second body 120 are omitted as well. In the embodiment, the keyboard 130 can be pivoted in the accommodating opening E of the second body 120 through at least one rotation-shaft 140. For example, two rotation-shafts 140 are respectively disposed at the left and right two sides of the keyboard 130, and each of the rotation-shafts 140 is located at the center of the side-edge of the keyboard 130. The design that the rotation-shaft 140 is located at the center of the keyboard 130 can avoid an excessive accommodating opening E due to an excessive moving range of the keyboard 130 when the keyboard 130 is turned over. In addition, for fixing the turning-over-angle of the keyboard 130 relatively to the body, in the embodiment, the rotation-shaft 140 has a torsional part 140a for fixing the turning-over-angle of the keyboard 130 relatively to the second body 120. The torsional part 140a surrounds the rotation-shaft 140 and is located in a recess 132 of the keyboard 130. The torsional part 140a is, for example, implemented with a damper, which the invention is not limited to.
FIG. 3B is a schematic diagram showing the chute in FIG. 3A moves to a fixing position relatively to the rotation-shaft. Referring to FIGS. 3B and 3A, in the embodiment, in addition to being turned over relatively to the second body 120, the keyboard 130 further can slide relatively to the second body 120, so that after the keyboard 130 rises up with turning relatively to the second body 120, the keyboard 130 slides to a fixed position to facilitate the operation of the user. For example, the keyboard 130 in FIG. 3A further includes at least one sliding portion 136, and the number of the sliding portions 136 is corresponding to the number of the rotation-shafts 140. Each of the sliding portions 136 is corresponding to a rotation-shaft 140 and disposed at a side of the keyboard 130 pivoted to the second body 120. The sliding portion 136 includes at least one chute 136a, and the rotation-shaft 140 goes through the chute 136a to be pivoted to the keyboard 130. In the embodiment, the number of the chute 136a of the sliding portion 136 is two and they are parallel to each other and respectively disposed on the side-walls at both sides of the recess 132. The extending direction of the recess 132 and the extending direction of the chute 136a are the same, so that the torsional part 140a can move with the rotation-shaft 140. When the keyboard 130 rises up with turning relatively to the second body 120, the keyboard 130 can move relatively to the rotation-shaft 140 through the chute 136a and thus move relatively to the second body 120.
In the embodiment, the sliding portion 136 further includes a first retaining portion 136b, and the first retaining portion 136b is a bump in the chute 136a. The rotation-shaft 140 further has a second retaining portion 140b correspondingly. The second retaining portion 140b is disposed around the rotation-shaft 140 and can move in the chute 136a. When the keyboard 130 slides to a fixed position relatively to the second body 120, the first retaining portion 136b and the second retaining portion 140b get interference by each other so as to fix the position of the keyboard 130 relatively to the second body 120. The invention however does not limit the shapes of the retaining portions 136b and 140b. In other unshown embodiments of the invention, the first retaining portion can be also a protrusive point and the second retaining portion can be correspondingly a recess where the body portion and the fixing portion are positioned by each other through the protrusive point and the recess are positioned by each other.
In summary, the electronic apparatus of the invention can adjust the angle of the keyboard in different operation modes by means of the keyboard able to be turned over, and thus, the keys can be covered and protected. When the first body is closed to the second body to make the display surface face the first surface, the keys on the keyboard are covered by the first body. When the first body is turned over relatively to the second body, the keyboard can be also turned over relatively to the second body, and when the appearance surface of the first body faces the second body to get closed, the keys of the keyboard and the second surface can be located at the same side so that the first body can still cover the keys on the keyboard. In addition, the body portion of the keyboard can slide relatively to the fixing portion, so that when the second body is unfolded from the first body, a good operation angle is provided to the user. As a result, the electronic apparatus of the embodiments can avoid the keys of the keyboard from exposure to make the keys scratched or fall off when the first body is turned over to the back of the second body.
It will be apparent to those skilled in the art that the descriptions above are several preferred embodiments of the invention only, which does not limit the implementing range of the invention. Various modifications and variations can be made to the structure of the invention without departing from the scope or spirit of the invention. The claim scope of the invention is defined by the claims hereinafter.
