This application claims the priority benefit of Taiwan application serial no. 108133419, filed on Sep. 17, 2019. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
The disclosure relates to a hinge module and a portable electronic device.
Portable computing devices, such as palmtop computers, portable computers, notebook computers, and personal digital assistants (PDAs) have become more and more popular. In general, a portable electronic device includes a base and a display assembly configured for the display of the base to comply with user operation and viewing purposes. In particular, as touch display technology advances through time, for portable computers, touch screens have gradually become the basic equipment.
In general, to provide the user with a favorable visual effect as well as designing notebook computers to be lighter, thinner, more compact, and smaller, pursuing a higher screen-to-body ratio or a slim bezel has now become the trend in notebook computer design. Accordingly, the hinge of notebook computers needs to adopt a sunken design to cope with such needs. In other words, the hinge is designed to generate a motion of moving downward relative to the device body while simultaneously rotating the device body as well as moving the screen toward the device body where the system is located.
However, limited by the rotating radius of the hinge, if the above needs are to be coped with, interference between device bodies may easily occur during the rotating process, making it difficult to achieve a favorable effect.
Embodiments of the disclosure provide a hinge module and a portable electronic device having a flexible hinge so that device bodies of the portable electronic device are relatively movable during a rotating process.
A hinge module according to an embodiment of the disclosure includes a first bracket, a first rotating shaft, a connecting rod, a second bracket, and a second rotating shaft. The first rotating shaft is disposed on the first bracket. The linking rod has a first end and a second end opposite to each other. The first end is pivoted to the first rotating shaft. A second rotating shaft is disposed on the second bracket and movably and pivotably connected to the first bracket. The second end of the linking rod is pivoted to the second bracket. In a process where the first bracket and the second bracket are rotated relatively, the first rotating shaft and the second rotating shaft are moved close to or away from each other.
A portable electronic device according to an embodiment of the disclosure includes a first device body, a first rotating shaft, a second device body, a second rotating shaft, a first bracket, a second bracket, and a connecting rod. The first rotating shaft is disposed on the first bracket. The linking rod has a first end and a second end opposite to each other. The first end is pivoted to the first rotating shaft. A second rotating shaft is disposed on the second bracket and movably and pivotably connected to the first bracket. The second end of the linking rod is pivoted to the second bracket. In a process where the first device body and the second device body are rotated relatively, the first bracket and the second bracket are rotated relatively following the first device body and the second device body, and the first rotating shaft and the second rotating shaft are moved close to or away from each other.
Based on the above, by disposing the hinge structure in the portable electronic device, the first device body and the second device body can be moved close to or away from each other through the corresponding relationship among the first rotating shaft, the second rotating shaft, and the linking rod of the hinge module when the first device body and the second device body are rotated relatively. In other words, the hinge module forms a configuration similar to a linkage mechanism. In this way, the second rotating shaft can be moved close to or away from the first rotating shaft when the second bracket is rotated relative to the first bracket. Accordingly, in the process where the first device body is rotated relative to the second device body to be opened or closed, the mechanical interference between the device bodies due to limitation of a fixed-type hinge or a fixed distance between rotating shafts can be avoided, and the device bodies can be opened or closed smoothly through rotation.
To make the above features and advantages of the disclosure more comprehensible, embodiments accompanied with drawings are described in detail as follows.
The accompanying drawings are included to provide a further understanding of the disclosure, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the disclosure and, together with the description, serve to explain the principles of the disclosure.
Reference will now be made in detail to the present preferred embodiments of the disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
The second racket 120 includes a bottom plate 121 and an extending part 122 standing below the bottom plate 121. A pivot hole 122b and a shaft hole 122a are disposed on the extending part 122. The second rotating shaft 133 has a moving part 133b, a pressing part 133c, and a shaft part 133a. The shaft part 133a penetrates through the shaft hole 122a. In addition, in the embodiment, the extending part 122 is considered as being located on the X-Z plane, and the shaft direction (Y-axis direction) of the second rotating shaft 133 is orthogonal to the X-Z plane.
Moreover, the moving part 133b is movably and pivotably coupled to the track 112a of the first bracket 110, and the pressing part 133c abuts against the standing plate 112 of the first bracket 110 along Y-axis. At the second end 134b, the linking rod 134 is arranged as a coupling structure and pivoted to the pivot hole 122b of the extending part 122 through a connecting assembly 132 (including components 132a and 132b riveted to each other). In addition, the extending part 122 is substantially pivotably sandwiched in the coupling structure.
Moreover, the hinge module 100 further includes a torque assembly 135 including a pressing member 135a, torque members 135b and 135c, and a locking member 135d. After the shaft part 133a of the second rotating shaft 133 penetrates through the shaft hole 122a, the pressing member 135a, the torque members 135b and 135c, and the locking member 135d are sequentially disposed on the shaft part 133a of the second rotating shaft 133 and abut against the extending part 122 of the second bracket 120. Accordingly, a torque force is provided between the second bracket 120 and the second rotating shaft 133 by the torque assembly 134 through the friction force which the torque assembly 135 can generate when the second bracket 120 and the second rotating shaft 133 are relatively pivotally rotated on Y-axis.

Then, referring to
Comparatively, when the first device body 200 and the second device body 300 are relatively rotated and closed from the expanded state shown in
In view of the foregoing, in the embodiment of the disclosure, by disposing the hinge structure in the portable electronic device, the first device body and the second device body can be moved close to or away from each other through the corresponding relationship among the first rotating shaft, the second rotating shaft, and the linking rod of the hinge module when the first device body and the second device body are rotated relatively. In other words, the hinge module forms a configuration similar to a linkage mechanism. In this way, the second rotating shaft can be moved close to or away from the first rotating shaft when the second bracket is rotated relative to the first bracket. Accordingly, in the process where the first device body is rotated relative to the second device body to be opened or closed, the mechanical interference between the device bodies due to limitation of a fixed-type hinge or a fixed distance between rotating shafts can be avoided, and the device bodies can be opened or closed smoothly through rotation.
