Description

portable electronic device

technical field

The invention relates to a portable electronic device, in particular to a portable electronic device capable of reducing structural interference or local friction between different components.

Background technique

Generally, a portable electronic device with a clamshell-like design is mainly composed of two parts pivoted to each other. Taking a notebook computer as an example, in design, the display end with the display screen is pivotally connected to the host end by a pivot component, so that the display end can rotate relative to the host end to switch to an open or a closed state.

Most of the existing notebook computers protrude the pivot assembly on the surface of the host end so that the display end is correspondingly pivoted. In order to meet different design specifications, some notebook computers have improved the pivot joint between the display end and the host end, such as adjusting the pivot joint position to be lower than the surface of the host end, so as to reduce the overall thickness of the computer or improve the streamlined overall appearance. However, for this type of design, if the pivot joint between the two is not properly designed, when the display end is rotated toward the host end to switch to the closed state, the display end and the host end will easily have a partial structural appearance. Friction will affect the smoothness of the rotation of the display end relative to the host end if it is light, and cause damage to the display end and the host end if it is severe, and bring users a bad experience.

Therefore, how to improve the shortcomings of the existing portable electronic devices and reduce the structural interference or local friction phenomenon generated when different components rotate relative to each other is really a topic worthy of research.

Please refer to Figure 1 and Figure 2 together. FIG. 1 is an overall schematic diagram of a portable electronic device 1 of the present invention; FIG. 2 is an exploded view of a partial structure of the portable electronic device 1 of the present invention. In one embodiment of the present invention, the portable electronic device 1 can be a notebook computer, or a combination of a tablet computer and its docking station, etc., but the present invention is not limited thereto, and can also be applied to a similar clamshell structure. Other portable electronic devices designed. In the following embodiments, the portable electronic device 1 of the present invention is described by taking a notebook computer as an example, but the present invention is not limited thereto.

As shown in Figures 1 and 2, the portable electronic device 1 of the present invention includes a base 10, a first component 20, a second component 30, two action components 40, two first pivot modules 50 and two second pivot modules. Connect to module 60. The base 10 includes two side surfaces 13 , a front end 11 and a rear end 12 opposite to each other. The first component 20 is pivotally connected to the front end 11 of the base 10 through two first pivot modules 50, and the second component 30 is pivotally connected to the rear end 12 of the base 10 through two second pivot modules 60, so that the first component 20 and the second component 30 can each rotate relative to the base 10 . In an embodiment of the present invention, the base 10 can be a base or a main frame structure of a device, the first component 20 is a display module, and the second component 30 is a keyboard module, but the present invention is not limited thereto.

The two action components 40 are symmetrically disposed on the two side surfaces 13 of the base 10 , so that each side 13 is correspondingly provided with an action component 40 . Each action assembly 40 includes a rod 41 and a biaxial rotation module 42. The rod 41 includes a first end 411 and a second end 412; Between, and the biaxial rotation module 42 is fixed on the side surface 13 of the base 10 . Here, the dual-axis rotation module 42 is a rotation module that can rotate based on two rotation axes that are substantially perpendicular to each other. Accordingly, the rod 41 can use the biaxial rotating module 42 as a fulcrum to generate rotational displacement along different planes relative to the base 10 .

Each action assembly 40 further includes an elastic assembly 43 , which is used to provide the reset function of the rod 41 after being rotated relative to the base 10 through its own elastic restoring force. Here the elastic component 43 is combined with the biaxial rotation module 42 to respond to the rotation of the biaxial rotation module 42 . In addition, each action component 40 further includes a damping component 44 . The damping component 44 is disposed on the second end 412 of the rod 41 , and the clamping effect on the second component 30 is provided by the damping component 44 .

The two first pivot modules 50 are respectively disposed on two sides of the base 10 . Each first pivot module 50 includes a main pivot component 51 , a driving component 52 and a shaft component 53 . The main pivotal member 51 is pivotally connected to the first part 20 through the shaft member 53, and one end of the main pivotal member 51 is fixed to the base 10, wherein the main pivotal member 51 may include a shaft corresponding to the same pivot L (that is, the shaft of the pivotal member 53 center) of the first cam 511 and the second cam 512; when the first component 20 is rotated to a specific angle (for example, greater than 90 degrees) relative to the base 10, the structural design of the two cams can provide the first component 20 Positioning effects that remain at that particular angle. Since the above-mentioned relevant settings for the two cams belong to the positioning function design of common pivotal components, no further details are given here.

The driving member 52 includes a protrusion 521 , and the driving member 52 also corresponds to the same pivot L, so that when the first component 20 rotates relative to the base 10 , the driving member 52 and its protrusion 521 also rotate accordingly. The setting position of the driver 51 corresponds to the first end 411 of the rod 41 of the action assembly 40, so as to achieve the purpose of driving the rod 41 by the rotation of the driver 51 within a certain rotation angle; and the driver 52 itself is also designed as A cam structure, and the protruding portion 521 is disposed on a side of the cam structure facing the first end 411 of the rod 41 .

In this embodiment, the protruding portion 521 is designed as a curved bump, so that the protruding portion 521 extends inward from the outer peripheral edge of the driving member 52 to near the center. In this way, when the driving member 52 rotates, it can not only drive the rod member 41 to rotate, but also change the position where the protrusion 521 contacts the first end 411 of the rod member 41 as the rotation angle of the driving member 52 changes. The invention is not limited thereto.

Please refer to FIG. 3 to FIG. 4B together. 3 is a schematic diagram of the first part 20 of the portable electronic device 1 of the present invention in an open state; FIG. 4A is a side view of the first part 20 of the portable electronic device 1 of the present invention in an open state; FIG. 4B is A top view of the first part 20 of the portable electronic device 1 in an open state of the present invention.

As shown in FIG. 3 , the rod 41 of the action assembly 40 can use the biaxial rotating module 42 as a fulcrum, and respectively use a first axis L1 substantially perpendicular to the side 13 of the base 10 as a rotation axis to move along the side 13 Rotate relative to the base 10 ; and use the second axis L2 substantially perpendicular to the first plane P as the rotation axis to rotate along the first plane P relative to the base 10 . Here, the first plane P is a plane that is substantially perpendicular to the side surface 13 and passes through the biaxial rotation module 42 .

As shown in FIG. 3 and FIG. 4A, when the portable electronic device 1 of the present invention is in an open state, an included angle θ is formed between the first part 20 and the base 10, and the included angle θ is an appropriate angle at this time. The user can perform corresponding input operations on the first component 20 and/or the second component 30 , and display image data through the first component 20 for the user to watch. For example, at this time, the angle range of the included angle θ is approximately between 70 degrees and 180 degrees, and the preferred appropriate angle is approximately between 90 degrees and 120 degrees, but it is not limited to this embodiment .

As shown in FIGS. 4A and 4B, when the first component 20 rotates in the aforementioned angular range relative to the base 10, the protrusion 521 of the driving member 52 has not yet contacted the rod 41 of the action assembly 40; that is to say , in this state, the driving member 52 will not produce any corresponding linkage operation on the rod 41, so that the rod 41 remains at the initial position.

Please refer to FIG. 5A and FIG. 5B together. 5A is a side view when the angle θ between the first part 20 and the second part 30 is smaller than the first angle when the first part 20 of the portable electronic device 1 of the present invention rotates from the open state to the closed state; 5B is a top view when the angle θ between the first part 20 and the second part 30 is smaller than the first angle when the first part 20 of the portable electronic device 1 rotates from the open state to the closed state. As shown in Figure 5A and Figure 5B, when the user wants to rotate the first part 20 of the portable electronic device 1 of the present invention from the open state to the closed state, the first part 20 needs to be rotated from the open state of Figure 5A Taking the first pivot module 50 as a fulcrum, it rotates relative to the base 10 in the direction of the arrow in the figure, so that the first part 20 can finally be superimposed on the base 10 and the second part 30 to be in a closed state.

During the rotation of the first component 20 relative to the base 10, since the shaft member 53 of the first pivot module 50 is connected to the first component 20, the rotation of the first component 20 will also drive the driving member 52 to rotate, Furthermore, the position of the protruding portion 521 of the driving member 52 relative to the first end 411 of the rod 41 is changed. And when the first component 20 rotates relative to the base 10 so that the angle θ formed between the first component 20 and the base 10 is a first angle, the protrusion 521 of the driver 52 (closer to the driver 52 The outer peripheral edge of the base 10) begins to contact the first end 411 of the rod 41, and pushes against the first end in the direction of the arrow in FIG. 411. In an embodiment of the present invention, the first angle corresponding to the included angle θ is about 60 degrees to 80 degrees, and the preferred first angle is about 70 degrees, but not in this embodiment limit.

The pushed rod 41 will rotate around the second axis L2, so that the second end 412 of the rod 41 moves toward the side 13 of the base 10 and passes through the through hole 131 on the side 13, The clamped second component 30 is clamped until the second end 412 ; and the clamped position of the second component 30 is away from the end where it is pivotally connected to the second pivot module 60 . The moving distance of the first end 411 of the rod 41 being pushed against is not less than the distance between the second end 412 of the rod 41 and the second component 30 . Accordingly, after the first end 411 of the rod 41 is pushed against by the protrusion 521 of the driving member 52 , the second end 412 of the rod 41 can be tightly pressed against the second component 30 .

Since the action assembly 40 is provided with a damping assembly 44 on the second end 412 of the rod 41, when the second end 412 contacts the second component 30, a greater frictional resistance is generated through the damping assembly 44, and the second end 412 can be provided more tightly. The effect of pressing against the second part 30 . In the present invention, action components 40 are provided on both symmetrical sides 13 of the base 10, so that when the angle θ between the first part 20 and the base 10 is smaller than the first angle during the rotation, it directly passes through the base 10. The rods 41 of the action components 40 on both sides respectively clamp the second component 30 .

Please refer to FIG. 5A to FIG. 6 together. FIG. 6 is a side view of the first part 20 of the portable electronic device 1 rotated to the closed state of the present invention. When the first part 20 continues to rotate toward the base 10 from the state shown in FIG. 521 continues to push against and withstand the first end 411 of the rod 41, so that the first end 411 of the rod 41 will rotate along the side 13 with the first axis L1 as the rotation axis of the driving member 52, and the rod 41 The second end 412 of the second end moves toward the bottom of the base 10 . At this time, the rotation direction of the first component 20 is the same as the rotation direction of the rod 41 along the side surface 13 . In addition, the protruding portion 521 of the driving member 52 is designed to have a sufficient length so that the first member 20 can continuously contact and push against the first end 411 of the rod 41 through the driving member 52 within a specific rotation angle. In this embodiment, the protruding portion 521 of the driving member 52 can provide the first component 20 between the first angle and 0 degrees, keeping the protruding portion 521 in contact with and pushing against the first end 411 of the rod 41 , But the present invention is not limited thereto.

Because the second part 30 is clamped by the second end 412 of the rod 41 on both sides, the second part 30 will also be driven by the rotating rod 41, and the second pivot module 60 is used as the fulcrum relative to the base. The seat 10 rotates, so that the other end of the second part 30 away from the second pivot module 60 moves toward the bottom of the base 10 ; finally, after the first part 20 is rotated to the closed state, it presents a shape as shown in FIG. 6 .

Accordingly, during the process of the first part 20 rotating from the open state relative to the base 10 to the closed state, through the interlocking operation between the first pivot module 50 and the second action assembly 40, the second part 30 is further driven The end away from the second pivot module 60 moves downward toward the base 10 to prevent the second component 30 from interfering with the rotation of the first component 20 or causing friction between the two.

Please refer to FIG. 7A to FIG. 7B together. Fig. 7A is the process of the second embodiment of the portable electronic device 1a of the present invention when the first part 20a rotates from the open state to the closed state, the angle θ between the first part 20a and the second part 30a is equal to the second angle 7B is a side view of the second embodiment of the portable electronic device 1a of the present invention after the first part 20a is rotated to the closed state.

This embodiment is a variation of the aforementioned first embodiment. As shown in FIG. 7A , in this embodiment, by changing the design of the driving member 52a of the first pivot module 50a, the first contact with the protrusion 521a of the driving member 52a and pushing against the rod 41a of the action assembly 40a is reduced. Rotation action angle of end 411a.

Similar to the aforementioned first embodiment, after the first component 20a is rotated so that the angle θ formed between it and the base 10a is smaller than the first angle, the protrusion 521a of the driver 52a will continue to contact and push against the rod The first end 411a of 41a. However, when the first component 20a continues to rotate toward the base 10a, so that the angle θ formed between the first component 20a and the base 10a is a second angle, the protrusion 521a of the driving member 52a is displaced with the rotation. Then, the pushing state of the first end 411a of the rod 41a is gradually released; and after the first end 411a of the rod 41a is no longer pushed by the external force, the rod 41a takes the biaxial rotation module 42a as the fulcrum and passes the elastic The component 43a returns to its original position first, so the clamping state of the second component 30a by the second end 412a of the rod 41a passing through the through hole 131a on the side 13a is also released, as shown in FIG. 7B . In an embodiment of the present invention, the second angle corresponding to the included angle θ is larger than 0 degrees and smaller than the first angle, and the preferred second angle is approximately between 0 degrees and 20 degrees, but not This example is limited.

At this time, although the clamping state of the second part 30a has been released by the rods 41a, the second part 30a will be blocked by the first part 20a approaching the base 10a or in the closed state, but still remains toward the base 10a. displacement below. After the first part 20a is reversely rotated to a certain angle from the closed state, and the second part 30a is no longer pressed by external force, it will return to its original position through another elastic component disposed inside the second pivot module 60a.

Certainly, the present invention also can have other various embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes All changes and modifications should belong to the protection scope of the claims of the present invention.
