Description
Technical Field
The invention relates to a portable electronic device.
Background
Portable electronic devices such as palm top computers, hand held computers, notebook computers, personal computer tablets, and Personal Digital Assistants (PDAs) are becoming more and more popular. Generally, portable computing devices employ a base unit and a display assembly configured for display of the base unit to accommodate user operation and viewing. Particularly, touch display technology and time have increased, and touch screens have become increasingly basic equipment for these portable computers.
Taking a notebook computer as an example, a rotating shaft (hinge) is used as a mechanism for causing movement between two machine bodies, however, once the notebook computer is matched with a touch screen, the rotating shaft needs to meet the force enough to support a user to press the touch screen while the machine bodies are unfolded. Meanwhile, the cables connected between the machine bodies also need to pass through the rotating shaft structure, so how to have the supporting force and the structural strength of the rotating shaft and meet the operation requirements of users becomes a problem required by related designers.
Furthermore, the existing rotating shaft structure often causes a significant gap between the screen and the system of the notebook computer, thereby causing poor visual effect. Therefore, how to provide a portable electronic device with supporting force, structural strength and visual habit of the user is a problem that needs to be considered and solved by the related technicians.
Disclosure of Invention
The invention is directed to a portable electronic device, which provides an angle change of a machine body during rotary opening and closing through an eccentric connecting rod between two rotating shafts so as to compensate a gap between the machine bodies.
According to an embodiment of the invention, a portable electronic device includes a first body, a second body, a first rotating shaft, a second rotating shaft and a connecting rod. The first rotating shaft is connected with the first machine body, and the second rotating shaft is connected with the second machine body. The connecting rod is provided with a first end and a second end which are opposite to each other, and the first end is pivoted to the first rotating shaft and eccentric to the rotating shaft of the first rotating shaft. The second end is pivoted to the second rotating shaft and eccentric to the rotating shaft of the second rotating shaft. The first body and the second body are moved away from or close to each other in the relative rotation opening and closing process through the first rotating shaft, the second rotating shaft and the connecting rod.
Based on the above, the body of the portable electronic device is provided with the double rotating shafts as the mechanism for rotating and opening and closing each other, and is further connected to the double rotating shafts by connecting rods, and the pivoting positions of the opposite ends of the connecting rods and the double rotating shafts are eccentric to the rotating shafts of the double rotating shafts respectively. Accordingly, when the first body and the second body are rotated to open and close, the structures of the bodies at the adjacent positions of the rotating shafts can be changed in relative positions due to the arrangement of the connecting rods, so that the bodies can be moved away from or moved close to each other, and the fixed distance between the bodies caused by the double rotating shafts can be compensated when the bodies are moved close to each other, so that the bodies can be maintained in a state that the rotating shafts are abutted against each other when being unfolded, and further, a user can have a better visual effect when operating the portable electronic device.

Detailed Description
Reference will now be made in detail to the exemplary embodiments of the present 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. 1 is a schematic diagram of a portable electronic device according to an embodiment of the invention. Fig. 2A and 2B are exploded views of the portable electronic device of fig. 1, respectively. Referring to fig. 1, fig. 2A and fig. 2B, in the present embodiment, the portable electronic device 100, for example, a notebook computer, includes a first body 110, a second body 120 and a rotating shaft module 130, wherein the rotating shaft module 130 is connected between the first body 110 and the second body 120, so that the first body 110 and the second body 120 can be opened and closed by rotating relatively. The rotation shaft module 130 includes a first rotation shaft A1, a second rotation shaft A2, and a link 138. The first rotating shaft A1 is connected to the first body 110, and the second rotating shaft A2 is connected to the second body 120. The connecting rod 138 has a first end E1 and a second end E2 opposite to each other, where the first end E1 is pivotally connected to the first rotation axis A1 and eccentric to the rotation axis X1 of the first rotation axis A1. The second end E2 is pivotally connected to the second rotating shaft A2 and eccentric to the rotating shaft X2 of the second rotating shaft A2. The first body 110 and the second body 120 are moved away from or close to each other in the process of relatively rotating the opening and closing by the first rotation axis A1, the second rotation axis A2 and the connection rod 138.
Fig. 2A shows a pair of rotary shaft modules 130 connected between the first body 110 and the second body 120, and since the constituent members of the pair of rotary shaft modules 130 are identical and for ease of recognition, reference numerals are only concentrated on the rotary shaft modules 130 on the right side. Further, the first rotating shaft A1 has a first shaft portion 131 and a first head 132 coaxially disposed with each other, and the first shaft portion 131 is connected to the first body 110 to be driven by the first body 110. The first head 132 has first eccentric holes 132b, 132c, and a first end E1 of the link 138 is pivotally connected to the first eccentric holes 132b, 132c. In this embodiment, the outer diameter of the first head 132 is larger than the outer diameter of the first shaft 131, the first head 132 further has a first notch 132a, and the first end E1 of the connecting rod 138 is substantially located in the first notch 132a and pivoted between the first eccentric holes 132b and 132c. Similarly, the second rotating shaft A2 has a second shaft portion 133 and a second head portion 134 coaxially disposed with each other, the second shaft portion 133 is connected to the second body 120 to be driven by the second body 120, the second head portion 134 has second eccentric holes 134b and 134c, and the second end E2 of the connecting rod 138 is pivotally connected to the second eccentric holes 134b and 134c. In the present embodiment, the outer diameter of the second head 134 is larger than that of the second shaft 133, the second head 134 further has a second notch 134a, and the second end E2 of the connecting rod 138 is located in the second notch 134a and pivotally connected between the second eccentric holes 134b and 134c.
In addition, the portable electronic device 100 further includes a torsion assembly composed of the components 135, 136 and 137, wherein the first rotation axis A1 and the second rotation axis A2 are inserted in parallel to each other in the torsion assembly, that is, the rotation axis X1 is parallel to the rotation axis X2.
Fig. 3 to 6 show partial side views of the portable electronic device in different states. Rectangular coordinates X-Y-Z are provided herein for ease of component description, with the aforementioned axes of rotation X1, X2 being parallel to the X axis. Referring to fig. 2B and fig. 3, further, the eccentricity d1 of the pivot point of the first end E1 and the first rotation axis A1 relative to the rotation axis X1 of the first rotation axis A1 is larger than the eccentricity d2 of the pivot point of the second end E2 and the second rotation axis A2 relative to the rotation axis X2 of the second rotation axis A2, in this embodiment, the eccentricity d1 is 1.87mm, and the eccentricity d2 is 1.38mm. In other words, the opposite ends of the link 138 have different movement strokes, and the eccentric state prevents the link from being in the same line with the connection line between the first rotation axis A1 and the second rotation axis A2, so as to prevent the first body 110 from sinking into the dead point of the link mechanism during movement and being unable to actuate.
Fig. 7 shows a schematic view of a shaft travel of the portable electronic device, which schematically illustrates the above related components, wherein the dashed circles represent the first shaft A1 and the second shaft A2, respectively, and the rotation axes X1 and X2 are taken as examples herein, and the solid circles represent the pivot points of the connecting rod 138 (at the opposite ends thereof) and the first shaft A1 and the second shaft A2, respectively. Next, please refer to fig. 3 to 6 in sequence and compare fig. 7, which shows a schematic stroke of combining the pivot points of the first rotating shaft A1 and the connecting rod 138 with the first rotating shaft A1 and the second rotating shaft A2 respectively based on the second body 120 and the second rotating shaft A2 in fig. 7, wherein the first timing T1 shown in fig. 7 is an illustration of the state shown in fig. 3, the second timing T2 is an illustration of the state shown in fig. 4, the third timing T3 is an illustration of the state shown in fig. 5, and the fourth timing T4 is an illustration of the state shown in fig. 6.
In detail, the period from the first timing T1 to the third timing T3 in the process of fig. 3 to fig. 6 is defined as the first stage of the relative rotation and expansion of the first body 110 and the second body 120, and the first body 110 and the second body 120 in the process have the motion characteristics of moving away from each other. In contrast, the period from the third timing T3 to the fourth timing T4 is defined as the second stage of the relative rotation and expansion of the first body 110 and the second body 120, and the first body 110 and the second body 120 in the process have the action feature of moving closer to each other. Therefore, the third timing T3 is regarded as a state transition formed between the first stage and the second stage, which represents a point at which the first body 110 and the second body 120 are shifted from each other to be shifted closer to each other. In the present embodiment, the angle (expansion angle) between the first body 110 and the second body 120 at the state transition is substantially 78% to 88% of the maximum expansion angle of the first body 110 and the second body 120 corresponding to the relationship between the eccentric distances d1, d2 of the connecting rod 138 and the first and second axes A1, A2. For example, the maximum deployment angle of the present embodiment is 140 degrees, and the deployment angle at the state transition is 115.3 degrees.
Referring to fig. 3 to 6, in the present embodiment, the first body 110 has a first surface 111 and a second surface 112 adjacent to the first rotation axis A1, wherein the second surface 112 is substantially in the same plane with the display surface of the portable electronic device 100, and the second body 120 has a third surface 121 and a fourth surface 122 adjacent to the second rotation axis A2, and during the process from closing to opening of the first body 110 and the second body 120, the first surface 111 is moved away from the third surface 121, and the second surface 112 is moved away from the fourth surface 122.
Furthermore, the first surface 111 is adjacent to the second surface 112 to form an (L-shaped) recess, the third surface 121 is adjacent to the fourth surface 122 to form a (wedge-shaped) protrusion, when the first body 110 and the second body 120 are closed, the protrusion faces and is located substantially in the recess, and when the first body 110 and the second body 120 are relatively unfolded, the protrusion moves away from the recess and the recess is limited to move below the second body 120.
In addition, when the first body 110 and the second body 120 are closed, the first surface 111 and the third surface 121 maintain a distance, that is, a space G11 shown in fig. 3, and when the first body 110 and the second body 120 are unfolded, the second surface 112 contacts the third surface 121. In other words, in the unfolding process from fig. 3 to fig. 6, the first rotating shaft A1, the second rotating shaft A2 and the connecting rod 138 are configured eccentrically with respect to the rotating shafts, so that the first body 110 and the second body 120 have a relative displacement at the rotating shaft module 130 to cause a moving-close effect, that is, the space G11 between the convex portion and the concave portion of fig. 3 between the first body 110 and the second body 120 is gradually transformed into the space G12 shown in fig. 4 and the space G13 shown in fig. 5 along with the unfolding of the rotation of the bodies, so that the third surface 121 of fig. 6 is abutted against the second surface 112 of the first body 110 without space. Here, the spaces G11, G12 and G13 are described with reference to the third surface 121 of the second body 120. The two broken lines representing the second surface 112 and the third surface 121 are treated separately so that they can be clearly identified, but the abutting relationship between the second surface 112 and the third surface 121 is not affected.
Referring to fig. 7 again, in the present embodiment, the axis center (the rotation axis X1) of the first rotation axis A1 and the axis center (the rotation axis X2) of the second rotation axis A2 form a first straight line L1 (shown by a solid line), the pivot point between the first end E1 and the first rotation axis A1 and the pivot point between the second end E2 and the second rotation axis A2 form a second straight line L2 (shown by a dot chain line), when the first body 110 and the second body 120 are closed, the first straight line L1 and the second straight line L2 intersect, and when the first body 110 and the second body 120 are unfolded (to the maximum unfolding angle), the first straight line L1 and the second straight line L2 do not intersect. In this embodiment, the correspondence between the eccentric link 138 and the first and second rotation axes A1 and A2 is shown.
It should be noted that, although the above description only describes the unfolding process of the first body 110 and the second body 120, it is expected that the closing process of the first body 110 and the second body 120 can be easily understood by reversing the above sequence.
In summary, in the above embodiment of the present invention, the body of the portable electronic device is provided with the dual-axis as the mechanism for rotating and opening/closing each other, and is further connected to the dual-axis by the connecting rod, and the pivot points of the opposite ends of the connecting rod and the dual-axis are eccentric to the rotation axes of the dual-axis respectively. Accordingly, when the first body and the second body are rotated to open and close, the structures of the bodies at the adjacent positions of the rotating shafts can be changed due to the arrangement of the connecting rods, namely, the space of the first body and the space of the second body at the adjacent positions are changed, so that the corresponding relation of mutual moving or approaching is caused, the fixed distance between the bodies caused by the fixed distance of the double rotating shafts can be compensated when the first body and the second body are mutually moved, the bodies can be maintained in a mutually propped state at the rotating shafts when being unfolded, and further, a user can have a better visual effect when operating the portable electronic device.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
