Description

Portable electronic device

Technical Field

The invention relates to a portable electronic device.

Background

Portable electronic devices such as palm top computers, portable computers, notebook computers, personal computer tablets, and Personal Digital Assistants (PDAs) have become increasingly popular. Typically, portable computing devices use a base unit and a display assembly configured for display of the base unit to fit user operation and viewing. Especially, the technology and time of touch display are increasing, and for these portable computers, the touch screen has become the basic equipment.

Taking a notebook computer as an example, a hinge (hinge) is used as a mechanism for causing movement between two bodies, however, once a touch screen is used, the hinge must be sufficient to support the force applied by a user on the touch screen while the bodies are unfolded. Meanwhile, the cables connected between the bodies also pass through the rotating shaft structure, so how to combine the supporting force and the structural strength of the rotating shaft to meet the operation requirements of users becomes a problem for the related designers.

Furthermore, the conventional hinge structure often causes a significant gap between the screen and the system of the notebook computer, thereby resulting in poor visual effect. Therefore, how to provide a portable electronic device with supporting force, structural strength and meeting the visual habits of users is a subject to be considered and solved by related technicians.

Disclosure of Invention

The invention relates to a portable electronic device, which provides angle change of a machine body during rotary opening and closing through an eccentric connecting rod between double rotating shafts so as to compensate a gap between the machine bodies.

According to an embodiment of the present 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 on the first rotating shaft and is eccentric to the rotating shaft of the first rotating shaft. The second end is pivoted to the second rotating shaft and is eccentric to the rotating shaft of the second rotating shaft. The first body and the second body move away from or close to each other in the process of relative rotation and opening and closing 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 dual rotating shafts as the mechanisms for rotating and opening/closing each other, and the connecting rods are connected to the dual rotating shafts, and the pivot joints between the two opposite ends of the connecting rods and the dual rotating shafts are respectively eccentric to the rotating shafts of the dual rotating shafts. Accordingly, when the first body and the second body are rotatably opened and closed, the structures of the bodies adjacent to the rotating shaft can be changed in relative positions due to the arrangement of the connecting rods so as to move away from or close to each other, and when the structures move close to each other, the fixed distance between the bodies due to the double rotating shafts can be compensated, so that the bodies can be maintained in a state of mutual abutting at the rotating shafts when being unfolded, and a user can have a better visual effect when operating the portable electronic device.

Detailed Description

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. 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. Referring to fig. 1, fig. 2A and fig. 2B, in the present embodiment, a portable electronic device 100, such as a notebook computer, includes a first body 110, a second body 120 and a hinge module 130, wherein the hinge 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 relative rotation. The hinge module 130 includes a first hinge A1, a second hinge A2, and a connecting rod 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 link 138 has a first end E1 and a second end E2 opposite to each other, and the first end E1 is pivoted to the first rotating shaft a1 and is eccentric to the rotating shaft X1 of the first rotating shaft a 1. The second end E2 is pivotally connected to the second rotation axis a2 and is eccentric to the rotation axis X2 of the second rotation axis a 2. The first body 110 and the second body 120 move away from or close to each other during the relative rotation and opening/closing process through the first rotation axis a1, the second rotation axis a2 and the connecting rod 138.

Fig. 2A shows a pair of hinge modules 130 connected between the first body 110 and the second body 120, and since the components of the pair of hinge modules 130 are the same and for identification, the reference numerals are only shown on the right side of the hinge module 130. Further, the first rotating shaft a1 has a first shaft portion 131 and a first head portion 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 the first end E1 of the connecting rod 138 is pivotally connected to the first

eccentric holes

132b, 132 c. 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 pivotally connected between the first

eccentric holes

132b and 132 c. Similarly, the second 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 134 c. In this embodiment, the outer diameter of the second head portion 134 is larger than the outer diameter of the second shaft portion 133, the second head portion 134 further has a second gap 134a, and the second end E2 of the connecting rod 138 is located in the second gap 134a and pivotally connected between the second

eccentric holes

134b and 134 c.

In addition, the portable electronic device 100 further includes a torsion assembly composed of the

components

135, 136 and 137, wherein the first rotating shaft a1 and the second rotating shaft a2 are inserted in the torsion assembly in parallel, i.e. the rotating shaft X1 is parallel to the rotating shaft X2.

Fig. 3 to 6 are partial side views of the portable electronic device in different states. Orthogonal coordinates X-Y-Z are also provided herein to facilitate component description, and the aforementioned axes of rotation X1, X2 are parallel to the X axis. Referring to fig. 2B and fig. 3, further, an eccentricity d1 of a pivot joint of the first end E1 and the first rotating shaft a1 with respect to a rotating shaft X1 of the first rotating shaft a1 is greater than an eccentricity d2 of a pivot joint of the second end E2 and the second rotating shaft a2 with respect to a rotating shaft X2 of the second rotating shaft a2, in the embodiment, the eccentricity d1 is 1.87mm, and the eccentricity d2 is 1.38 mm. In other words, the opposite ends of the connecting rod 138 have different moving strokes, and due to the eccentric state, the connecting line between the first rotating shaft a1 and the second rotating shaft a2 is prevented from being in the same straight line, so as to prevent the first body 110 from sinking into the dead point of the connecting rod mechanism and being unable to operate during the moving process.

Fig. 7 is a schematic diagram of the pivot stroke of the portable electronic device, which schematically illustrates the above related components, wherein the dashed circles represent the first pivot a1 and the second pivot a2, respectively, and the rotation axes X1 and X2 are used as examples, and the solid circles represent the pivot joints of (the two opposite ends of) the link 138 and the first pivot a1 and the second pivot a2, respectively. Next, referring to fig. 3 to 6 in sequence and referring to fig. 7, it is shown that the first body 110 and the second body 120 rotate and unfold gradually from the closed state of fig. 3 to the unfolded state shown in fig. 6, it should be noted that fig. 7 is a stroke schematic diagram in which the second body 120 and the second rotating shaft a2 thereof are used as a reference, and the first rotating shaft a1 and the connecting rod 138 are respectively combined with the pivot joints of the first rotating shaft a1 and the second rotating shaft a2 to form rotating shafts, wherein the first timing T1 shown in fig. 7 is an example of the state shown in fig. 3, the second timing T2 is an example of the state shown in fig. 4, the third timing T3 is an example of the state shown in fig. 5, and the fourth timing T4 is an example of the state shown in fig. 6.

In detail, in the process of fig. 3 to 6, the period from the first timing T1 to the third timing T3 is defined as a first phase of the relative rotation and unfolding of the first body 110 and the second body 120, in which the first body 110 and the second body 120 have an action characteristic of moving away from each other. In contrast, the period from the third timing T3 to the fourth timing T4 is defined as a second stage of the relative rotation and unfolding of the first body 110 and the second body 120, in which the first body 110 and the second body 120 have motion characteristics of moving close to each other. Accordingly, the third timing T3 is regarded as a state transition formed between the first phase and the second phase, which represents that the first body 110 and the second body 120 are switched from moving away to moving close to each other. In the present embodiment, corresponding to the eccentric distances d1 and d2 between the connecting rod 138 and the first and second rotating shafts a1 and a2, an included angle (unfolding angle) of the portable electronic device 100 at the turning point of the first and

second bodies

110 and 120 in the state is substantially 78% to 88% of the maximum unfolding angle of the first and

second bodies

110 and 120. 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 rotating axis a1, wherein the second surface 112 is substantially on the same plane as 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 rotating axis a2, and in the process of closing the first body 110 and the second body 120 to unfolding, the first surface 111 moves away from the third surface 121, and the second surface 112 moves away from the fourth surface 122.

Furthermore, the first surface 111 adjoins the second surface 112 to form an (L-shaped) recess, the third surface 121 adjoins the fourth surface 122 to form a (wedge-shaped) protrusion, when the first body 110 and the second body 120 are closed to each other, the protrusion faces and is substantially located in the recess, when the first body 110 and the second body 120 are relatively unfolded, the protrusion moves away from the recess, and the recess moves 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, i.e., 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 process of switching from fig. 3 to fig. 6 to the unfolding process, the first rotating shaft a1, the second rotating shaft a2 and the connecting rod 138 are eccentrically arranged with respect to the rotating shafts, so that the structures of the first body 110 and the second body 120 at the rotating shaft module 130 are relatively displaced to cause the approaching effect, that is, the space G11 between the convex portion and the concave portion of the first body 110 and the second body 120 shown in fig. 3 is gradually switched to the space G12 shown in fig. 4 and the space G13 shown in fig. 5 along with the rotation and unfolding of the bodies, so that the third surface 121 shown in fig. 6 is abutted against the second surface 112 of the first body 110 and no space exists. Here, the spaces G11, G12 and G13 are descriptions based on the third surface 121 of the second body 120. In order to clearly identify the second surface 112 and the third surface 121, two dotted lines representing the two surfaces are separately processed, 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, a first straight line L1 (shown by a solid line) is formed by an axis of the first rotating shaft a1 (the rotating shaft X1) and an axis of the second rotating shaft a2 (the rotating shaft X2), a second straight line L2 (shown by a dotted chain line) is formed at a pivot joint of the first end E1 and the first rotating shaft a1 and a pivot joint of the second end E2 and the second rotating shaft a2, when the first body 110 and the second body 120 are closed, the first straight line L1 intersects the second straight line L2, and when the first body 110 and the second body 120 are unfolded (to a maximum unfolding angle), the first straight line L1 does not intersect the second straight line L2. In the present embodiment, the corresponding relationship between the eccentric link 138, the first rotating shaft a1 and the second rotating shaft a2 is illustrated.

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 embodiments of the present invention, the body of the portable electronic device is further connected to the dual rotating shafts by the connecting rods, in addition to the dual rotating shafts as the mechanisms for mutually rotating and opening/closing, and the pivot points of the two opposite ends of the connecting rods and the dual rotating shafts are respectively eccentric to the rotating shafts of the dual rotating shafts. Accordingly, when the first body and the second body are rotatably opened and closed, the structures of the bodies adjacent to the rotating shaft can be changed in relative positions due to the arrangement of the connecting rod, that is, the spaces of the first body and the second body adjacent to each other are changed, so as to cause a corresponding relationship of mutual moving away or moving close, so that a fixed distance between the bodies due to the fixed distance of the double rotating shafts can be compensated when the bodies are moved close to each other, the bodies can be maintained in a state of mutual abutting at the rotating shaft when being unfolded, and 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 used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
