Description

Portable electronic device

Technical Field

The invention relates to a portable electronic device.

Background

In the electronic products of the prior art, in order to avoid overheating of high power electronic components such as microprocessors, display chips, etc., heat dissipation devices (such as fans) are often disposed to reduce the temperature thereof, and flip-top electronic devices (such as notebook computers) are no exception. Meanwhile, for the notebook computer, in order to consider the feeling of the user during the operation and avoid the air outlet of the fan facing the user or the places where the user places his or her hands, the air outlet of the fan is generally placed behind the main unit to avoid the hot air from directly blowing to the user.

However, as the electronic products are increasingly thinned, the screen of the flip-top electronic device is often lifted relative to the host via the hinge structure, and then a part of the flip-top is moved to the rear of the host, so as to reduce the thickness of the host and achieve a more beautiful appearance. However, this operation conflicts with the aforementioned heat dissipation device, that is, after the cover is opened, the portion of the cover behind the main unit blocks the air outlet effect of the fan, which is not favorable for heat dissipation.

Based on the above, how to consider and solve the problem of the related people while considering both the light and thin appearance and the effective heat dissipation effect.

Disclosure of Invention

The invention provides a portable electronic device, wherein one machine body is pivoted to be close to or far away from the other machine body through a rotating shaft.

The invention relates to a portable electronic device, which comprises a first body, a second body, a cam and a connecting rod. The first body has a counterbore. The second machine body is provided with a rotating shaft, and movably and rotatably penetrates through the hole expanding. The cam is assembled on the side surface of the rotating shaft to rotate coaxially with the rotating shaft. The connecting rod has opposite first and second ends. The first end is pivoted to the cam, and the second end is pivoted to the first body. When the second body pivots relative to the first body through the rotating shaft, the cam rotates along with the rotating shaft and drives the cam and the rotating shaft to move along the reaming hole through the connecting rod, so that the second body moves close to or away from the first body.

Based on the above, the portable electronic device movably pivots the rotating shaft of the second body in the hole-expanding hole of the first body, and further assembles the cam and the connecting rod in a matching manner on the side surface of the rotating shaft, and meanwhile, the other end of the connecting rod is pivoted with the fixing position of the first body. Therefore, when the second body rotates relative to the first body through the rotating shaft, one end of the connecting rod pivoted on the cam moves along with the cam, while the other end of the connecting rod is still pivoted at the fixed position of the first body and cannot correspondingly move, so that the second body can be pushed through pushing the rotating shaft, namely, the second body is pushed, and relative movement is generated between the second body and the first body. Accordingly, the portable electronic device can achieve the effect of relative displacement while the body pivots relatively, so as to facilitate the change of the appearance of the body or the matching of corresponding functions.

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. Referring to fig. 1, in the present embodiment, a portable electronic device 100 is, for example, a notebook computer, and includes a first body 110 (e.g., a host), a second body 120 (e.g., a screen), and a rotating shaft structure, where the rotating shaft structure is configured to allow the first body 110 and the second body 120 to pivot relatively, and further cause the first body 110 and the second body 120 to generate a relative displacement, so as to change a relative position of the bodies before and after pivoting, and facilitate changing an appearance of the bodies and achieving a specific function, where relevant components constituting the rotating shaft structure are respectively disposed in the first body 110 and the second body 120, and only a part P of the rotating shaft structure is partially enclosed in fig. 1, which will be further described later.

Fig. 2 to 4 are partial component schematic diagrams of the portable electronic device of fig. 1 in different states, which are used to illustrate internal component schematic diagrams of the portable electronic device 100 in fig. 1 at a portion P, wherein the state shown in fig. 4 corresponds to fig. 1, which is used to describe a fully unfolded state of the portable electronic device 100, but the invention is not limited to the unfolded angle thereof. Fig. 2 is a diagram illustrating the portable electronic device 100 in a fully closed state, and fig. 3 is a diagram illustrating the portable electronic device 100 in one of states between the fully closed state and the fully opened state. Meanwhile, rectangular coordinates are provided in the present embodiment to facilitate the description of the members. Moreover, fig. 2 to 4 only show a part of the components in a perspective cross-sectional view, and for the sake of easy recognition, the first body 110 and the second body 120 are not shown in the same cross-section.

Referring to fig. 2 to fig. 4, in the present embodiment, the first body 110 has a hole 112, and the second body 120 has a rotating shaft 122, and the rotating shaft 122 movably and rotatably penetrates through the hole 112. Furthermore, the portable electronic device 100 further includes a cam 130 and a link 140, wherein the cam 130 is assembled on a side surface of the rotating shaft 122 to rotate coaxially with the rotating shaft 122. Here, the shaft 122 rotates about the axis a1 to open and close the second body 120 relative to the first body 110, and the axis a1 is substantially parallel to the X axis of the rectangular coordinate, and drives the cam 130 to rotate about the axis a 1. The link 140 has a first end E1 and a second end E2 opposite to each other, wherein the first end E1 is pivotally connected to the cam 130, and the second end E2 is pivotally connected to the fixed portion of the first body 110, that is, the link 140 only rotates along the Y-Z plane (or other plane parallel to the Y-Z plane) with the second end E2 relative to the first body 110 without causing relative displacement between the second end E2 and the first body 110.

Based on the above structure, when the second body 120 pivots relative to the first body 110 through the rotating shaft 122, the cam 130 rotates along with the rotating shaft 122, and the connecting rod 140 drives the cam 130 and the rotating shaft 122 to move along the enlarged hole 112, so that the second body 120 moves closer to or away from the first body 110. As shown in fig. 2 to 4, it represents that the second body 120 is far from the first body 110, and conversely, the process from fig. 4 to fig. 2 represents that the second body 120 is close to the first body 110.

In detail, the portable electronic device 100 of the present embodiment further includes a moving element 150 and a first fixed shaft 160, which are fixedly connected to the rotating shaft 122 and located in the first body 110, wherein the moving element 150 has a first guiding groove 152. The first fixing shaft 160 is fixed in the first body 110 by a structural member 162, the first fixing shaft 160 and the first guiding groove 152 are movably coupled together, and the extending direction of the first guiding groove 152 is consistent with the extending direction of the enlarged hole 112, wherein the extending direction is parallel to the Y axis, so that the moving member 150 can move along the Y axis. In addition, the first end E1 of the link 140 is pivotally connected to the convex portion 132 of the cam 130, and the second end E2 is pivotally connected to the first fixed shaft 160. Here, the first fixed shaft 160 extends along the X axis (toward the positive X axis direction), passes through the first guiding groove 152, and is pivotally connected to the second end E2 of the connecting rod 140.

For the connecting rod 140, since the second end E2 is substantially fixed on the first body 110 (pivotally connected to the fixed position of the first body 110, i.e. the first fixed shaft 160), when the first end E1 of the connecting rod 140 rotates along with the convex portion 132 of the cam 130, the first end E1 moves toward or away from the second end E2, whereas the connecting rod 140 is a rigid body, the relative distance between the first end E1 and the second end E2 is fixed, and only the moving member 150 and the rotating shaft 122 (both of which may be considered as a whole) of the above-mentioned members can move due to the enlarged hole 112 and the first guiding groove 152, so that the moving member 150 and the rotating shaft 122 move relative to the first body 110 due to the above-mentioned relative movement, so as to enable the first end E1 of the connecting rod 140 to move toward or away from the direction of the second end E2 smoothly. That is, when the second body 120 and the rotating shaft 122 thereof pivot, the cam 130 and the connecting rod 140 are driven (and the second body 120 and the rotating shaft 122 thereof are in a movable state), so as to push the second body 120 and the rotating shaft 122 thereof by a reaction force.

Accordingly, when the second body 120 is closed relative to the first body 110, the axis a1 of the shaft 122 is substantially located between the first end E1 and the second end E2, as shown in fig. 2; when the second body 120 is unfolded relative to the first body 110, the first end E1 is substantially located between the axis a1 of the rotating shaft 122 and the second end E2, as shown in fig. 4.

Referring to fig. 3 and 4 and fig. 2, in the present embodiment, the portable electronic device 100 further includes a heat dissipation component (e.g., a fan 180), and the side surface of the first body 110 further has a plurality of air outlets 114, which are opposite to the air outlet of the fan 180. Here, since the enlarged hole 112 and the first guiding groove 152 respectively extend along the Y axis, the rotating shaft 122 and the second body 120 also generate relative displacement along the Y axis during the pivoting process, and in the state shown in fig. 3, the side portion 124 of the second body 120 and the air outlet 114 on the side surface of the first body 110 generate a gap G1, and similarly, when the second body 120 is further unfolded relative to the first body 110, the side portion 124 of the second body 120 and the air outlet 114 on the side surface of the first body 110 generate a gap G2, wherein the gap G2 is greater than the gap G1. That is, the side portion 124 of the second body 120 and the fan 180 are opposite to each other across the side surface of the first body 110, but the body pivots to generate the gap G1 or G2, so that the heat dissipation airflow with heat discharged from the fan 180 through the air outlet 114 can be smoothly discharged out of the first body 110, thereby providing a better heat dissipation effect.

On the other hand, the moving member 150 of the embodiment further has a second guiding groove 154, and the portable electronic device 100 further includes a second fixing shaft 170 fixedly disposed on the first body 110. The second guide groove 154 and the second fixing shaft 170 are movably coupled to each other, wherein the second guide groove 154 extends in the same direction as the first guide groove 152 (both extending along the Y-axis), and the second fixing shaft 170 (extending along the Z-axis) is orthogonal to the first fixing shaft 160 (extending along the X-axis). Here, the second fixing shaft 170 includes a connecting portion 172 and a stopping top portion 174, wherein the connecting portion 172 passes through the second guiding groove 154 and is fixedly connected between the reference surface a2 of the first body 110 and the stopping top portion 174. In the embodiment, the outer diameter of the stopping top 174 is substantially larger than the width of the second guiding groove 154 along the X axis, so that the stopping top 174 can abut against a portion of the moving member 150 at the second guiding groove 154 to generate a limiting effect on the moving member 150 along the Z axis. That is, the stopping top 174 can provide a Z-axis restraining force during the moving process of the moving member along the Y-axis, so as to prevent the moving member 150 from falling off or overturning or toppling over when the moving member 150 pivots along with the second body 120 and the rotating shaft 122 relative to the first body 110 (in the process of unfolding the bodies, the rotating shaft 122 is substantially away from the pivot point of the connecting rod 140 and the first fixing shaft 160, i.e. the moment arm of the second body 120 and the rotating shaft 122 relative to the pivot point is gradually increased, thereby causing an increase in torque, so as to offset these newly increased torques, the moving member 150 is fixed on the first body 110 along the Z-axis by the second fixing shaft 170, thereby achieving the desired effect). Meanwhile, when the second body 120 is a touch screen, this can also avoid the second body 120 shaking (wobbble) when the user operates the touch screen.

Fig. 5 and fig. 6 are respectively equivalent schematic views of a portable electronic device in a hinge structure according to another embodiment of the invention. For example, the changing state of the rotating shaft structure is shown by taking the negative X-axis direction in fig. 2 to 4 as the viewing angle, and the same components between different embodiments are shown by the same reference numerals and are not described again. Referring to fig. 5 and 6, different from the previous embodiments, in the previous embodiments of fig. 2 to 4, the counterbore 112 and the first guide groove 152 both extend along the Y axis, and in the embodiments of fig. 5 and 6, the extension direction of the counterbore 212 and the extension direction of the first guide groove 252 have the same slope with respect to the reference plane A3 of the first body, so that the second body can be lifted relative to the reference plane A3 (parallel to the X-Y plane) while being unfolded relative to the first body, as in the pivoting process of the bodies of fig. 5 to 6 (corresponding to fig. 2 to 4), the moving member 250 and the rotating shaft can generate displacement along the Z axis in addition to displacement along the Y axis, so that other structural appearance changes can be generated while the bodies are pivoted, thereby improving the variability of the portable electronic device during operation to attract users. It is not limited to what the slope is, and it can be determined according to the structural design requirement.

Fig. 7 is an equivalent schematic view of a portable electronic device in a hinge structure according to another embodiment of the invention. Unlike the previous embodiments shown in fig. 5 and 6, the moving element 350 of the present embodiment further has an inclined surface 351 located at the periphery of the second guiding groove 354 and abutting against the stop top portion 374, and the slope of the inclined surface 351 with respect to the reference surface a4 of the first body is the same as the slope of the extension direction of the counterbore 312 with respect to the reference surface a4 and the slope of the extension direction of the first guiding groove 352 with respect to the reference surface a 4. This allows the moving member 350 to increase the contact area with the second fixing shaft 370 by providing the inclined surface 351, so that the lifting action of the moving member 350 caused by the relative expansion of the machine body can be more stable. Similarly, in the embodiment shown in fig. 5 to 7, the lifting movement of the second body relative to the first body while the second body is unfolded can also make the heat dissipation airflow blown out by the fan through the air outlet more unobstructed, thereby facilitating heat dissipation.

In summary, in the above embodiments of the invention, the rotating shaft of the second body is movably pivoted to the enlarged hole of the first body, and the cam and the connecting rod are further assembled on the side surface of the rotating shaft in a matching manner, and the other end of the connecting rod is pivoted to the fixed position of the first body. Therefore, when the second body rotates relative to the first body through the rotating shaft, one end of the connecting rod pivoted on the cam moves along with the cam, while the other end of the connecting rod is still pivoted at the fixed position of the first body and cannot correspondingly move, so that the second body can be pushed through pushing the rotating shaft, namely, the second body is pushed, and relative movement is generated between the second body and the first body. Accordingly, the portable electronic device can achieve the effect of relative displacement while the body pivots relatively, so as to facilitate the change of the appearance of the body or the matching of corresponding functions.

In addition, in different embodiments, by changing the slopes of the counterbores and the first guide groove, and the plane where the moving member abuts against the top of the stop at the second guide groove, the second body and the rotating shaft can perform relative motions such as lifting and the like relative to the first body while pivoting, so that the variability of the body of the portable electronic device can be improved to attract the eyes of a user.

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 as defined in the appended claims.
