Description

Foldable electronic device

This new creation is about a folding electronic device.

With the continuous advancement of technology, folding electronic devices using flexible screens have gradually become the future development trend, and the component configuration of such devices, such as smart phones, usually allows the flexible screen to be installed in two bodies In the above, when the two bodies are relatively rotated by the rotating shaft to be folded or unfolded, the flexible screen can be switched between the bent and folded state and the unfolded and flattened state.

However, when the flexible screen is bent, there is a difference in the inner and outer dimensions (such as the arc length of the bend) at the bending place due to the thickness, so it is necessary to change the change when designing the rotating shaft mechanism Listed as considerations to avoid damage to the flexible screen during bending or unfolding.

The novel creation provides a foldable electronic device which provides a response mechanism to compensate for the difference in the length of the flexible screen during the state of bending and unfolding the flexible screen, so that the process operates smoothly and avoids damage to the flexible screen .

The folding electronic device created by the novel includes a first body, a second body, a pivoting chain, a plurality of airbags, and a flexible screen. The pivot link is pivotally connected between the first body and the second body. The pivot chain includes a plurality of pivot pieces that are pivotally connected to each other, a groove exists between two adjacent pivot pieces, and the airbag is correspondingly disposed in the groove. The flexible screen connects the first body and the second body, and part of the flexible screen bears on the airbag to undulate with the airbag.

Based on the above, based on the above, the foldable electronic device has a hinged chain connected between the two bodies and an airbag provided at the groove of the hinged chain to allow the flexible screen to remove the portion connecting the first body and the second body In addition, there are also parts that depend on the airbag and can fluctuate as the air pressure of the airbag changes. According to this, whether the airbag is inflated or not can produce different bending states for the pivot chain, and accordingly, the first body and the second body can be switched between the folded state and the expanded state, thereby adjusting the relative opening and closing angle between the bodies .

At the same time as the above-mentioned opening and closing, the state of the airbag can also provide size compensation for the flexible screen, that is, the flexible screen can correspond to the different shapes and contours of the airbag when inflating or deflating, and also generates relative to the pivotal connection. Whether the chain is recessed or not, where the flexible screen in the folded state can be recessed relative to the pivoting member as the airbag deflates, so that the flexible screen can provide further retracted space when folded, correspondingly, in In the flat state, the flexible screen fills the grooves due to the inflation of the airbag. In addition to allowing the airbag to support the flexible screen, the airbag inflation will also provide support for the flexible screen during the transition to the deployed state. 3. Flattening to avoid wrinkling or even damage to the flexible screen. In other words, the folding electronic device can provide the corresponding adjustment force required for the flexible screen to be converted between bending and flattening by the inflation of the airbag, to overcome (compensate) the different states of the flexible screen due to the thickness The difference between the inside and outside dimensions.

4 is a partial side view of the folding electronic device of FIG. 1. 5 is a partial side view of the folding electronic device of FIG. 2. Please refer to FIG. 1, FIG. 3 and FIG. 4 firstly, in this embodiment, the controller unit 170 drives the gas driving unit 160 to deflate the airbag 150 to gather the pivot chain 140 to form a bend and make the first body 110 The second body 120 and the second body 120 are folded by the pivotal link 140 to form a folded state. Conversely, please refer to FIG. 2, FIG. 3 and FIG. 5, the control unit 170 drives the gas driving unit 160 to inflate the airbag 150 to relax the pivotal link 140 to form a flattening, and to make the first body 110 and the second body 120 The flattened pivot link 140 forms the unfolded state.

In other words, the control unit 170 can adjust the air pressure of the airbag 150 by the gas driving unit 160 to control the bending degree of the pivot chain 140 and the opening angle of the first body 110 and the second body 120. In this way, the user can adjust the folding electronic device 100 to an opening angle suitable for operation accordingly.

In detail, please refer to FIGS. 2 and 5 again, the flexible screen 130 is divided into a first part 131, a second part 132 and a third part 133, wherein the third part 133 is connected to the first part 131 and the second part 132 In between, the first part 131 is disposed on the first body 110, the second part 132 is disposed on the second body 120, and the third part 133 is attached to the surface of the airbag 150 exposed to the groove 141, so when the airbag 150 is placed as described above When inflated or inflated, the third portion 133 of the flexible screen 130 will be recessed into the groove 141 or fill the groove 141 as the airbag 150 rises and falls. As shown in FIG. 5, the airbag 150 will drive the first body 110, the second body 120 and the pivot chain 140 to assume a deployed state due to the above-mentioned inflation action. At this time, the surface of the airbag 150 is substantially in contact with the adjacent pivot members A1-A7 Flush, that is, the state where the groove 141 is filled, so the third portion 133 of the flexible screen 130 can smoothly bear on the surface of the inflated airbag 150, which is equivalent to the weathered airbag 150 to the flexible screen 130 Provides pulling and spreading forces, so that the surface of the flexible screen 130 can be flat without wrinkles.
