Description

Rotating shaft module and portable electronic device

Technical Field

The invention relates to a rotating shaft module and a portable electronic device.

Background

Portable computing devices such as palm top computers, laptop 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.

Generally, in order to provide better visual effects for users, and to meet the trend of notebook computers toward being light, thin and small, the requirement for providing a larger screen area or a thin frame has become the current design trend of notebook computers. Accordingly, the hinge of the notebook computer must be designed in a sink type to meet the above requirement, that is, the hinge can generate a movement mode of moving downward relative to the body while providing the body with a relative rotation, and at the same time, the screen can approach the body where the system is located.

However, if the rotation radius of the rotating shaft is required to meet the above requirement, the mutual interference between the machine bodies is often caused during the rotation process, and the desired effect is not easily achieved.

Disclosure of Invention

The invention provides a rotating shaft module and a portable electronic device, which are provided with a movable rotating shaft so that a machine body of the portable electronic device can move relatively in the rotating process.

The rotating shaft module comprises a first support, a first rotating shaft, a connecting rod, a second support and a second rotating shaft. The first rotating shaft is arranged on the first bracket. 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 with the first rotating shaft. The second rotating shaft is arranged on the second support, the second rotating shaft is movably and pivotally connected with the first support, and the second end of the connecting rod is pivotally connected with the second support. In the process of relative rotation of the first bracket and the second bracket, the first rotating shaft and the second rotating shaft move close to or away from each other.

The invention relates to a portable electronic device, which comprises a first machine body, a first rotating shaft, a second machine body, a second rotating shaft, a first support, a second support and a connecting rod. The first rotating shaft is arranged on the first bracket. 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 with the first rotating shaft. The second rotating shaft is arranged on the second support, the second rotating shaft is movably and pivotally connected with the first support, and the second end of the connecting rod is pivotally connected with the second support. In the process of relative rotation of the first body and the second body, the first support and the second support rotate relative to the first body and the second body, and the first rotating shaft and the second rotating shaft move close to or move away from each other.

Based on the above, when the portable electronic device is configured with the rotating shaft module and the first body and the second body rotate relatively, the first body and the second body can move closer to or away from each other through the corresponding relationship between the first rotating shaft and the connecting rod of the rotating shaft module. In other words, the hinge module forms a linkage mechanism, so that the second hinge can move closer to or away from the first hinge as the second frame rotates relative to the first frame. Therefore, in the process of opening and closing along with the relative rotation of the first machine body relative to the second machine body, the machine bodies are prevented from being limited by fixed rotating shafts or rotating shafts with fixed intervals to easily cause mechanism interference, so that the machine bodies can be smoothly rotated to open and close.

In order to make the aforementioned and other features and advantages of the invention more comprehensible, embodiments accompanied with figures are described in detail below.

Detailed Description

Fig. 1 is a schematic diagram of a portable electronic device according to an embodiment of the invention. Fig. 2A and 2B are schematic views of the hinge module of fig. 1 from different viewing angles. Orthogonal coordinates X-Y-Z are also provided herein to facilitate component description. Referring to fig. 1, fig. 2A and fig. 2B, in the present embodiment, the portable electronic device 10 includes a first body 200, a second body 300, and a hinge module 100 connected to the first body 200 and the second body 300, so that the first body 200 and the second body 300 can be rotated and opened relative to each other through the hinge module 100. Herein, the hinge module 100 includes a first bracket 110, a second bracket 120, a first hinge 131, a second hinge 133 and a connecting rod 134, wherein the first hinge 131 is disposed on the first bracket 110, the second hinge 133 is disposed on the second bracket 120, the first bracket 110 is assembled to the first body 200, and the second bracket 120 is assembled to the second body 300.

Fig. 2A and 2B are schematic views of the hinge module of fig. 1 from different viewing angles. Referring to fig. 2A and 2B, in the present embodiment, the first bracket 110 includes a bottom plate 111 and a vertical plate 112, wherein the bottom plate 111 is located on an X-Y plane and assembled to the first body 200, and the vertical plate 112 is located on an X-Z plane and has a rail 112A and a positioning hole 112B. The first rotating shaft 131 has a positioning portion 131b, an abutting portion 131a and a shaft portion 131c, wherein the positioning portion 131b is embedded in the positioning hole 112b to be positioned on the X-Z plane, and abuts against the vertical plate 112 along the Y axis by the abutting portion 131a abutting against the vertical plate 112. The connecting rod 134 includes a first end 134a and a second end 134b opposite to each other, which are pin-jointed holes, respectively, wherein the first end 134a is pin-jointed to the shaft portion 131c of the first rotating shaft 131.

The second bracket 120 includes a bottom plate 121 and an extending portion 122 standing below the bottom plate 121, and the extending portion 122 is provided with a pivot hole 122b and a shaft hole 122 a. The second shaft 133 has a moving portion 133b, an abutting portion 133c and a shaft portion 133a, wherein the shaft portion 133a is disposed through the shaft hole 122a, and in the embodiment, the extending portion 122 is regarded as being located on the X-Z plane, and the axial direction (Y-axis direction) of the second shaft 133 is orthogonal to the X-Z plane.

Furthermore, the moving portion 133b is movably and pivotally coupled to the rail 112a of the first bracket 110, and the abutting portion 133c abuts against the vertical plate 112 of the first bracket 110 along the Y-axis. The connecting rod 134 presents a coupling structure at the second end 134b and is pivoted with the pivoting hole 122b of the extension portion 122 by the connecting component 132 (including the

components

132a and 132b riveted to each other), and the extension portion 122 is substantially pivotally clamped (clamped) in the coupling structure.

In addition, the hinge module 100 further includes a torsion assembly 135 including an abutting member 135a,

torsion members

135b and 135c, and a locking member 135 d. After the shaft 133a of the second rotating shaft 133 passes through the shaft hole 122a, the abutting member 135a, the

torsion members

135b, 135c and the locking member 135d are sequentially disposed on the shaft 133a of the second rotating shaft 133 and abut against the extending portion 122 of the second bracket 120, so that when the second bracket 120 and the second rotating shaft 133 pivot relatively along the Y-axis through the torsion member 135, the torsion force generated by the torsion member 135 provides a torsion force between the second bracket 120 and the second rotating shaft 133.

Fig. 4A to 4D are side views showing the hinge module in different states. Referring to fig. 4A, based on the above configuration of the components, the first rotating shaft 131, the second rotating shaft 133, the connecting member 132, the connecting rod 134 and the torsion member 135 of the present embodiment form the torsion link mechanism 130, wherein the axial direction of the first rotating shaft 131 and the axial direction of the second rotating shaft 133 are parallel to each other, so that the torsion link mechanism 130 performs link motion on substantially the same plane (X-Z plane) as shown in fig. 4A. Here, fig. 4A is as shown in fig. 1, that is, the first body 200 and the second body 300 are in a state of being folded and closed, and in this state, the distance between the second rotating shaft 133 and the first rotating shaft 131 is the maximum.

Next, referring to fig. 4B to 4D, as the first body 200 pivots and expands relative to the second body 300, that is, the second body 300 rotates clockwise based on the first body 200, at this time, due to the connection relationship of the members of the torsion link mechanism 130, the first rotating shaft 131 rotates counterclockwise, the second rotating shaft 133 rotates clockwise, the link 134 rotates counterclockwise and simultaneously drives the second rotating shaft 133 to slide along the track 112a toward the negative X-axis direction, so as to gradually lean against the first rotating shaft 131 at one end of the track 112a, until the second rotating shaft 133 approaches the first rotating shaft 131 and the distance therebetween is the minimum as shown in fig. 4D.

Conversely, when the first body 200 and the second body 300 are gradually rotated and closed relatively from the unfolded state shown in fig. 4D, as shown in fig. 4D, the state of fig. 4A is sequentially switched, and the second rotating shaft 133 moves along the track 112a toward the positive X-axis direction and is away from the first rotating shaft 131 due to the rotation of the second bracket 120, until the position is reset to the position shown in fig. 4A.

In summary, in the above embodiments of the invention, the portable electronic device configures the hinge module such that when the first body and the second body rotate relatively, the first body and the second body can move closer to or away from each other through the corresponding relationship between the first hinge, the second hinge and the connecting rod of the hinge module. In other words, the hinge module forms a linkage mechanism, so that the second hinge can move closer to or away from the first hinge as the second frame rotates relative to the first frame. Therefore, in the process of opening and closing along with the relative rotation of the first machine body relative to the second machine body, the machine bodies are prevented from being limited by fixed rotating shafts or rotating shafts with fixed intervals to easily cause mechanism interference, so that the machine bodies can be smoothly rotated to open and close.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
