Description

  The present invention relates to an electronic device in which a main body housing and a display housing are connected to each other so as to be rotatable by a hinge mechanism.

  In recent years, tablet personal computers (tablet PCs) having a touch panel type liquid crystal display and no physical keyboard are rapidly spreading. The tablet PC is easy to carry and input operations can be easily performed using a touch panel.

  However, since the tablet PC does not have a physical keyboard, for example, it may hinder long text input operations. In view of this, a convertible tablet personal computer (convertible PC) has been proposed in which a display housing having a display can be rotated from 360 degrees to 360 degrees with respect to a main body housing having a keyboard (for example, a patent). Reference 1). A convertible PC can be used in two ways: a normal notebook personal computer (notebook PC) and a tablet PC, so that it is very convenient for the user.

JP2013-155874A

  By the way, a sub device such as a camera module facing the back surface or an antenna module for wireless communication may be mounted on an upper portion of a display housing in a general notebook type PC. In some cases, a sub-device such as a camera module facing the front at the top of the display or an antenna module for wireless communication may be mounted on the top of the housing of the tablet PC.

  However, in the convertible PC according to the prior art, when the display casing is rotated up to 360 degrees and used as a tablet PC, the other end of the main body casing and the display casing having one end connected by a hinge mechanism. (Open end) has a structure that overlaps at the same position. For this reason, when a sub device is mounted on the display housing, the sub device is covered by the main body housing when used in a tablet PC. Then, when the sub device is a camera module, photographing cannot be performed, and when the sub device is an antenna module, the transmission / reception sensitivity may be lowered by a metal member or the like in the main body housing.

  The present invention has been made in consideration of the above-described problems of the prior art, and can effectively function the sub-device provided in the display casing regardless of the rotation angle of the display casing with respect to the main body casing. It is an object to provide an electronic device that can be used.

  The electronic device according to the present invention is configured such that one end of a main body housing having a keyboard and one end of a display housing having a display are rotatably connected by a hinge mechanism, and the main body housing, the display housing, This is an electronic device that can be rotated from a 0 degree position where the display and the keyboard face each other through a 180 degree position where the display and the keyboard face in the same direction and parallel to each other and to a 360 degree position where the back faces of the display and the keyboard face each other. In the 360 degree position, the open end of the main body casing opposite to the one end to which the hinge mechanism is connected is opposite to the one end of the display casing to which the hinge mechanism is connected. The open end on the side is displaced from each other, and one open end protrudes from the other open end, and has the one open end. The main body housing or the display housing is characterized by having a sub-device portion protruding than the other open end.

  According to such a configuration, even when the display housing is rotated to the 360 degree position, the sub-device such as the camera module and the antenna module provided in the display housing is covered by the main body housing. Is avoided. For this reason, a subdevice can be functioned effectively regardless of the rotation angle of the display housing with respect to the main body housing.

  The 360 degree position may be configured such that the open end of the display casing protrudes beyond the open end of the main body casing.

  In this case, if the sub device is a camera module provided facing the back surface of the display housing, the camera module is used as a rear camera in a notebook PC usage pattern, and further a tablet PC usage pattern. It can be used effectively as a front camera.

  If the sub device is an antenna module provided in the display housing, the antenna module can be prevented from being covered by the main body housing, so that the transmission / reception sensitivity can always be kept good.

  The hinge mechanism has a first shaft connected to the display housing and a second shaft connected to the main body housing, and the first shaft and the 360 ° position at the 0 degree position and the 360 degree position. The second shaft may be arranged offset from each other in a direction along the open end from the one end of the main body casing. If it does so, the front-back direction position of the end surface in the open end part of the display housing | casing in a 0 degree position and a main body housing | casing can be made to correspond, and the external appearance quality in a closed form can be improved, and also this end surface in 360 degree position The sub-device can be made to function effectively by shifting the position.

  The hinge mechanism has a biaxial structure in which the second axis starts rotating after the first axis rotates to the rotation end point position, and the first axis rotates from the 0 degree position to the 180 degree position. If the second axis rotates from the 180 degree position to the 360 degree position, the subdevice always remains in the main body case at the 360 degree position regardless of the situation of the rotation operation of the display case by the user. Covering with the body can be avoided, and high operability and functionality are ensured.

  According to the present invention, even when the display housing is rotated to the 360 degree position, it is avoided that the sub-device such as the camera module and the antenna module provided in the display housing is covered by the main body housing. Is done. For this reason, a subdevice can be functioned effectively regardless of the rotation angle of the display housing with respect to the main body housing.

  The electronic device 10 according to the present embodiment can be suitably used as a notebook PC in a state where the display housing 14 is rotated to an angular position of about 90 degrees with respect to the main body housing 16 (see FIGS. 1 and 3). ), A so-called convertible PC that can be suitably used as a tablet PC when the display casing 14 is rotated to a position of 360 degrees with respect to the main casing 16 (see FIG. 6). The present invention can be suitably applied to any electronic device capable of rotating the display housing up to a position of 360 degrees with respect to the main body housing, such as a mobile phone, a smartphone, or an electronic notebook, other than such a convertible PC. .

  The touch pad 19 and keyboard provided on the upper surface 16a of the main body housing 16 while visually recognizing the display 18 provided on the front surface 14a of the display housing 14 on the basis of the usage form in the notebook PC shown in FIG. 20, the front side is referred to as the front side (front), the back side is referred to as the rear side (rear), the thickness direction of the main body casing 16 is referred to as the up-down direction, and the width direction is referred to as the left-right direction. explain.

  Further, for convenience of explanation, regarding the angular positions of the main body casing 16 and the display casing 14 by the hinge mechanism 12, the display casing 14 is completely closed with respect to the main body casing 16, and the display 18 is connected to the main body casing 16. The posture facing the upper surface 16a is called a 0-degree position (see FIG. 2), and the description will be made with the angle in the opening direction while rotating the display housing 14 with the 0-degree position as a reference. That is, the posture in which the display housing 14 and the main body housing 16 are substantially orthogonal is called a 90-degree position (see FIGS. 1 and 3), and the display 18 and the upper surface 16a of the main body housing 16 face the same direction (upward). The postures parallel to each other are called 180-degree positions (see FIG. 4). Further, the posture in which the display housing 14 is substantially orthogonal to the lower surface (rear surface) 16b side of the main body housing 16 is called a 270 degree position (see FIG. 5), and the rear surface 14b of the display housing 14 and the lower surface 16b of the main body housing 16 are called. The posture where and face each other is called a 360-degree position (see FIG. 6). For the 0 degree position, 90 degree position, 180 degree position, 270 degree position, and 360 degree position, the exact angle indicated by the angle number depends on the structure of the main body housing 16, the display housing 14, or the hinge mechanism 12. Naturally, the angular position slightly deviates from the position, and the angular position including these deviated angular positions is also referred to as a 0 degree position in the present embodiment.

  As shown in FIGS. 1 to 6, the electronic device 10 includes one end (rear end) of a main body casing 16 having a keyboard 20 and one end (lower end) of a display casing 14 having a display 18. The left and right hinge mechanisms 12 and 12 are pivotally connected.

  The display housing 14 is configured to be thinner and flatter than the main body housing 16, and is connected to the main body housing 16 by a hinge mechanism 12 provided at the lower end portion of the display housing 14 and passes through the hinge mechanism 12 (not shown). The main body housing 16 is electrically connected by a cable. The display 18 is configured by, for example, a touch panel type liquid crystal display device.

  A camera module 22 is provided on the back surface 14b of the upper end (open end 14c) opposite to the lower end (connection end) to which the hinge mechanism 12 of the display housing 14 is connected. The camera module 22 is provided facing the back surface 14 b of the display housing 14, and is a camera capable of photographing the rear of the display housing 14, and the photographed image can be displayed on the display 18. Although not shown, a camera module facing the front surface 14a of the open end 14c of the display housing 14 may be added.

  The main body housing 16 is formed in a flat box shape, and is connected to the display housing 14 by a hinge mechanism 12 provided at the rear end thereof. Input means such as a touch pad 19 and a keyboard 20 are provided on the upper surface 16 a of the main body housing 16, and various electronic components such as a board, a computing device, and a memory (not shown) are provided inside the main body housing 16. ing.

  As shown in FIGS. 2 to 6, the hinge mechanism 12 enables the display housing 14 to be rotated from the 0 degree position to the 360 degree position by the biaxial structure. The hinge mechanism 12 includes a first shaft 24 that is non-rotatably connected to the display housing 14, a second shaft 26 that is non-rotatably connected to the main body housing 16, and the first shaft 24 and the first shaft 24. And a hinge housing 28 for rotatably holding the two shafts 26. The hinge housing 28 is inclined with respect to the direction in which the main body housing 16 and the display housing 14 overlap at the 0 degree position and the 360 degree position, that is, at the 0 degree position (360 degree position). The first shaft 24 on the body 14 side is offset rearward (front) from the second shaft 26 on the main body housing 16 side.

  The hinge mechanism 12 in this embodiment has a structure according to a specific example described later, for example, and the first shaft 24 rotates and the second shaft 26 does not rotate from the 0 degree position to the 180 degree position (FIGS. 2 to 4). The second shaft 26 rotates and the first shaft 24 does not rotate from the 180-degree position to the 360-degree position (see FIGS. 4 to 6).

  In such an electronic device 10, an end surface 16 d serving as an edge of the front end portion (open end portion 16 c) opposite to the rear end portion (connection end portion) to which the hinge mechanism 12 of the main body housing 16 is connected, and a display The position in the front-rear direction coincides with the end surface 14d which is the edge of the open end 14c of the housing 14 at the 0 degree position shown in FIG. At this time, the rear end portion of the main body casing 16 is at a position offset forward from the lower end portion (rear end portion in this case) of the display casing 14, that is, the length of the main body casing 16 in the front-rear direction is the display casing. It is shorter than 14.

  And since the 1st axis | shaft 24 and the 2nd axis | shaft 26 are offset in the front-back direction as mentioned above, since the hinge mechanism 12 is 360 degree position shown in FIG. 6, the front-back direction position of the end surfaces 14d and 16d is displaced. . Specifically, at the 360 degree position illustrated in FIG. 6, the open end 14 c of the display housing 14 protrudes forward from the open end 16 c of the main body housing 16, and the end surface 14 d is forward of the end surface 16 d. It is in the position shifted. Accordingly, the camera module 22 is not covered by the open end portion 16c of the main body housing 16 even in the usage form as the tablet PC shown in FIG. 6, and the camera module 22 is used as the front camera of the tablet PC. can do. In other words, the camera module 22 is provided at a portion (open end portion 14c) where the display housing 14 protrudes with a position shifted forward from the end surface 16d of the main body housing 16 at the 360 degree position shown in FIG. Therefore, it can be used regardless of the rotational angle position of the display housing 14.

  Next, a specific configuration example of the hinge mechanism 12 will be described.

  FIG. 7 is an operation explanatory view schematically showing a turning operation of the display housing 14 with respect to the main body housing 16 using the hinge mechanism 12, and FIG. 7 (A) is a diagram showing a 0 degree position. 7B is a diagram showing a 90-degree position, FIG. 7C is a diagram showing a 180-degree position, and FIG. 7D is a diagram showing a 270-degree position. (E) is a figure which shows a 360-degree position.

  As shown in FIGS. 7A to 7E, the hinge mechanism 12 includes a first shaft 24 extending in the left-right direction, a second shaft 26 installed in parallel with the first shaft 24, A hinge housing 28 that rotatably supports the first shaft 24 and the first shaft 26 is provided. At a position sandwiched between the first shaft 24 and the second shaft 26 inside the hinge housing 28, a float pin 30 supported so as to be reciprocally movable and rotatable between the first shaft 24 and the second shaft 26. Is provided.

  The first shaft 24 is coupled to the display housing 14 in a non-rotatable state by inserting and fixing both ends of the first shaft 24 in fitting holes (not shown) provided in the display housing 14. The second shaft 26 is coupled to the main body housing 16 in a non-rotatable state by fitting and fixing both ends of the second shaft 26 into fitting holes (not shown) provided in the main body housing 16. The first shaft 24 and the second shaft 26 are rotatably held by a hinge housing 28 and protrude from the left and right side surfaces of the hinge housing 28 to be connected to the display housing 14 and the main body housing 16, respectively. . Accordingly, the display housing 14 is supported so as to be rotatable with respect to the hinge housing 28 together with the first shaft 24, and the main body housing 16 is supported so as to be rotatable relative to the hinge housing 28 together with the second shaft 26. A stopper piece 32 protrudes from one outer surface of the hinge housing 28. The stopper piece 32 is a member that comes into contact with the display housing 14 that is positioned 180 degrees by the opening operation and restricts further rotation (see FIGS. 7C to 7E).

  The float pin 30 is movable along a long hole (not shown) formed in the hinge housing 28. On the outer peripheral surfaces of the first shaft 24 and the second shaft 26, arc-shaped grooves 24a and grooves 26a into which a part of the float pin 30 can be fitted are formed. As shown in FIG. 7A, the groove portions 24 a and 26 a are formed at positions that face obliquely upward in a state where the display housing 14 is at a 0 degree position with respect to the main body housing 16. Accordingly, at the 0 degree position shown in FIG. 7A, the float pin 30 is fitted into the groove 26a of the second shaft 26 by gravity. The float pin 30 is a member that is fitted into the groove portion 24a or the groove portion 26a according to the rotation angle of the display housing 14 and restricts the rotation of the fitted first shaft 24 or second shaft 26. .

  A rotation operation of the display housing 14 and the main body housing 16 by the hinge mechanism 12 will be described.

  When the display housing 14 is rotated in the opening direction from the main body housing 16, first, the float pin 30 is in the first position between the 0 degree position and the 180 degree position shown in FIGS. 7A to 7C. The two shafts 26 are fitted in the grooves 26a. For this reason, the rotation of the second shaft 26 is restricted, and the main body housing 16 and the second shaft 26 and the hinge housing 28 are integrated. Accordingly, the display housing 14 rotates with the first shaft 24 and the first shaft 24 as a rotation axis with respect to the main body housing 16, the second shaft 26, and the hinge housing 28. For example, FIG. And it can be used as a notebook PC as shown in FIG.

  7C, the back surface 14b of the display housing 14 abuts against a stopper piece 32 provided on the hinge housing 28, and the rotation about the first shaft 24 as a rotation shaft is restricted. The In this state, the groove portion 24a of the first shaft 24 faces obliquely downward so as to face the groove portion 26a of the second shaft 26, and the float pin 30 can be received.

  If the display housing 14 is rotated further in the opening direction than the 180 ° position, the display housing 14 and the first shaft 24 are now connected via the stopper piece 32 as shown in FIG. The hinge housing 28 is integrated with the hinge housing 28 and starts rotating about the second shaft 26 as a rotation axis. Along with this rotation, the float pin 30 is detached from the groove portion 26a of the second shaft 26 and fits into the groove portion 24a of the first shaft 24, so that the main body housing 16, the second shaft 26 and the hinge housing 28 are integrated. Is released. Accordingly, as shown in FIGS. 7D and 7E, in the opening direction from the 180 degree position, the display housing 14, the first shaft 24, and the hinge housing 28 are integrated, and the main body housing 16 is rotated with the second shaft 26 as a rotation axis.

  Finally, as shown in FIG. 7 (E), when the display housing 14 turns around to the lower surface 16b side of the main body housing 16 and the stopper piece 32 contacts the lower surface 16b of the main body housing 16, the rotation is restricted. Thus, the position becomes 360 degrees, and the tablet PC can be used as shown in FIG.

  As described above, in the electronic device 10 according to the present embodiment, when the display housing 14 is opened with respect to the main body housing 16 and is set to the 360 degree position, the hinge mechanism 12 of the main body housing 16 is connected. The open end portion 16c opposite to the one end portion and the open end portion 14c opposite to the one end portion to which the hinge mechanism 12 of the display housing 14 is connected are displaced from each other, and the display housing 14 The open end portion 14 c protrudes from the open end portion 16 c of the main body housing 16. Here, the display housing 14 has a camera module 22 as a sub device at a portion (open end portion 14 c) protruding from the open end portion 16 c of the main body housing 16.

  As a result, even when the display housing 14 is rotated and changed to the usage form as the tablet PC shown in FIG. 6, the camera module 22 provided on the back surface 14 b of the display housing 14 is mounted on the main body housing. Covering with the body 16 is avoided. For this reason, the camera module 22 used as the rear camera in the usage pattern of the notebook PC can be effectively used as the front camera in the usage pattern of the tablet PC. In addition, as a subdevice mounted in the display housing | casing 14, the antenna module 22a for wireless communication other than the camera module 22, various function switches 22b, etc. can be illustrated (refer FIG. 6). Even when the antenna module 22a and the function switch 22b are provided, the electronic device 10 allows these subdevices to function effectively regardless of the rotation angle of the display housing 14 with respect to the main body housing 16. Can do. That is, when the antenna module 22a is provided, it is avoided that the antenna module 22a is covered with the main body housing 16 in the usage form of the tablet PC and the transmission / reception sensitivity is lowered, and the function switch 22b is provided. In this case, it is avoided that the function switch 22b is covered with the main body housing 16 in the usage form of the tablet PC and cannot be operated.

  In the electronic apparatus 10, the first shaft 24 and the second shaft 26 are open in the front-rear direction, that is, from one end of the main body housing 16 on the hinge mechanism 12 side at the 0 degree position and the 360 degree position of the display housing 14. The hinge mechanisms 12 are used that are offset from each other in the direction toward 16c. As a result, as shown in FIG. 2, the front-rear direction positions of the end surfaces 14d and 16d of the display housing 14 and the main body housing 16 at the 0 degree position can be matched to improve the appearance quality in the closed configuration, and 360 At the angular position, the end surfaces 14d and 16d can be displaced so that the sub-device functions effectively.

  As shown in FIGS. 8 and 9, the first shaft 24 and the second shaft 26 are not offset in the front-rear direction at the 0-degree position and the 360-degree position, and the positions in the front-rear direction are the same. A hinge mechanism 34 may be used. However, when this hinge mechanism 34 is used, as shown in FIG. 8, the front and rear positions of the end surfaces 14d and 16d of the display housing 14 and the main body housing 16 at the 0 degree position are displaced, and the open end portion 14c. Projecting forward from the open end 16c. As a result, even at the 360-degree position shown in FIG. 9, the open end portion 14c of the display housing 14 can be protruded forward from the open end portion 16c of the main body housing 16, and the sub-device such as the camera module 22 can be effectively used. Can be made to function.

  In the case of this embodiment, the hinge mechanism 12 has a two-axis structure in which the second shaft 26 starts rotating after the first shaft 24 rotates to the rotation end point position. The first shaft 24 rotates, and the second shaft 26 rotates from the 180 degree position to the 360 degree position. That is, if the hinge mechanism 12 has a biaxial structure in which the first shaft 24 and the second shaft 26 are freely rotatable at any angular position from the 0 degree position to the 360 degree position, the 360 degree shown in FIG. Since the first shaft 24 and the second shaft 26 are freely rotatable at the position, the display housing 14 can be moved in the front-rear direction. Accordingly, depending on the situation of the user's rotation operation, the end surface 14d of the display housing 14 and the end surface 16d of the main body housing 16 may coincide with each other at the 360 ° position in substantially the same manner as the 0 ° position shown in FIG. 22 may be covered by the main housing 16.

  On the other hand, in the present embodiment, since the first shaft 24 and the second shaft 26 use the hinge mechanism 12 configured to be selectively rotatable according to the rotation angle, the display is displayed at the 360-degree position. The end surface 14d of the housing 14 and the end surface 16d of the main housing 16 are always displaced as shown in FIG. 6, and only the display housing 14 cannot be moved in the front-rear direction from this state. For this reason, the camera module 22 is always exposed at the 360-degree position regardless of the state of the user's rotation operation, and high operability and functionality are ensured. Of course, depending on the specifications of the electronic device 10, a hinge mechanism having a structure in which the two axes are always freely rotatable may be used.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.

  In the above embodiment, the open end portion 14c of the display housing 14 projects forward from the open end portion 16c of the main body housing 16 at the 360-degree position, and the camera module 22, antenna module 22a, etc. A configuration for mounting a sub-device is illustrated. On the other hand, the open end portion 16c of the main body housing 16 projects forward from the open end portion 14c of the display housing 14 at the 360-degree position, and the sub-device provided in the main body housing 16 is rotated. It is good also as a structure which can be made to function effectively in an angular position.
