Description

Foldable electronic device

The present invention relates to a foldable electronic device, and in particular to a foldable electronic device with a lifting mechanism.

Foldable electronic devices, such as notebook computers, have a large number of users due to their advantages of portability and wide application. Traditional foldable electronic devices simply allow two bodies to be pivoted to each other through a pivot structure. Since foldable electronic devices are small in size, the height of the screen of the foldable electronic device after unfolding is not very high, which is not conducive to for users to view. Therefore, foldable electronic devices with lifting mechanisms appear on the market.

Figure 1 is a schematic diagram of a conventional foldable electronic device. It should be noted that, for the sake of clarity, the lifting mechanism 13 is drawn at an exaggerated scale in FIG. 1 . In actual product, the distance between the first pivot point P1 and the fourth pivot point P2 is not so large. As shown in FIG. 1 , the foldable electronic device 10 includes a first body 11 , a second body 12 and a lifting mechanism 13 . The second body 12 is movably disposed on the first body 11 through the lifting mechanism 13 . The lifting mechanism 13 is a four-bar linkage mechanism, including a first link 13a, a second link 13b, a third link 13c and a fourth link 13d that are pivoted in sequence. The middle lifting mechanism 13 defines a first pivot point P1, a second pivot point P2, a third pivot point P3 and a fourth pivot point P. The first link 13a is provided on the first body 11, the second link 13b is pivotally connected to the first link 13a through the first pivot point P1, and the third link 13c is pivotally connected to the second link 13b through the second pivot point P2. The fourth link 13d is pivotally connected to the first link 13a through the third pivot point P3, and the fourth link 13d is pivotally connected to the third link 13c through the fourth pivot point P4. However, under the premise of pursuing thinning and narrowing the frame of the foldable electronic device 10, the distance between the second pivot point P2 and the fourth pivot point P4 will be too close. When the second body 12 is forced to move relative to the first pivot point, When the body 11 is opened to a specific angle, the external force F exerted by the second body 12 on the fourth link 13d will pass through the second pivot point P2 and the fourth pivot point P4 at the same time, causing the lifting mechanism 13 to be stuck and unable to operate. Therefore, the third The second body 12 cannot be further deployed relative to the first body 11 .

Therefore, when the existing foldable electronic device uses the above-mentioned lifting mechanism 13, the distance between the second pivot point P2 and the fourth pivot point P4 cannot be too close, which results in the lifting mechanism 13 occupying a relatively large area of the second body 12. There is too much space, so the second body 12 cannot effectively narrow the frame, which is not conducive to the thinning of the foldable electronic device 10. In addition, if the distance between the second pivot point P2 and the fourth pivot point P4 is shortened, although It can effectively achieve the narrow frame of the second body 12 and the thinning of the foldable electronic device 10 , but it will cause the lifting mechanism 13 to get stuck at the above-mentioned dead center and cannot operate.

Please refer to Figures 4 and 5. In order to clearly explain the operating principle of the lifting mechanism 130, the lifting mechanism 130 is defined here as a first pivot point P1, a second pivot point P2, a third pivot point P3, and a fourth pivot point. Pivot point P4 and a fifth pivot point P5.

The first link 131 and the second link 132 are pivotally connected to each other through the first pivot point P1. The second link 132 and the third link 133 are pivotally connected to each other through the second pivot point P2.

When the first rod 334a rotates relative to the first connecting rod 331, the second elastic member 352 can push the third rotating shaft 337 to slide toward the bottom side of the groove seat 351, pushing the first rod 334a further. Keeping this movement margin can further ensure that the lifting mechanism 330 is stuck at the dead center of the mechanism, which helps to increase the smoothness of the lifting mechanism 330's operation. Please further refer to FIG. 14 . When the lifting mechanism 330 moves further, the second elastic member 352 will push the third rotating shaft 337 to move to the upper side of the groove base 351 , for example, back to the original position.
