Description

Foldable electronic device

This new creation is about an electronic device, and especially about a folding electronic device.

With the continuous advancement of technology, folding electronic devices with flexible screens have gradually become the future development trend, and in such devices, such as smart phones, flexible screens are usually installed on two bodies, and when the 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 state and the unfolded flat state.

However, when the flexible screen is bent, there are changes in the circumference of the inside and outside of the bend. Therefore, when designing the mechanism of the shaft, the changes need to be taken into consideration to avoid the bend of the flexible screen. Or damage in the process of unwinding.

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 shaft assembly, a second body, a sliding assembly, and a flexible screen. The rotating shaft assembly is pivotally connected between the first body and the sliding assembly. The sliding component is slidably coupled to the second body. The flexible screen is arranged on the first body and the second body. The first body and the second body are switched between the unfolded state and the folded state by the rotating shaft assembly. During the transition from the folded state to the unfolded state, the rotating shaft assembly and the sliding assembly drive the first body and the second body to generate relative displacement to compensate for the difference in length between the folded state and the unfolded state of the flexible screen.

Based on the above, by the corresponding arrangement of the sliding assembly and the second body, and the pivot assembly is pivotally connected between the sliding assembly and the first body, when the body of the folding electronic device is switched from the folded state to the unfolded state , The rotating shaft component and the sliding component drive the first body and the second body to produce relative displacement, that is, the second body is moved away from the sliding component and the rotating shaft component, and the relative distance between the first body and the second body is stretched accordingly, so that The relative distance of the stretching can correspond to the size (length change) of the flexible screen during the transition from the folded state to the unfolded state.

In this way, by the relative displacement of the above-mentioned components, the motion consistency between the flexible screen and the first body and the second body is maintained, that is, the flexible screen and the first body and the second body are not moved relative to each other In the case of interference, it can avoid the situation that the flexible screen that should be flattened will still be deformed or wrinkled due to the dimensional changes caused by bending and unfolding.

The link A1 of the assembly 140 is pivotally connected to the extending shaft portion 131e of the slider 131. The lock attachment 133 passes through the rail 131d and is locked to the cylinder 121a positioned on the inner surface of the component 121, so that the sliding member 131 can slide relative to the second body 120 by the lock attachment 133 being movably fitted to the rail 131d.

Further, the sliding member 131 has a first portion 131a and a second portion 131b, the connecting rod A1 of the rotating shaft assembly 140 is pivotally positioned on the extending shaft portion 131e on the first portion 131a, and the second portion 131b is oriented from the first portion 131a The second body 120 extends, and the second portion 131b has the above-mentioned rail 131d.

FIG. 4A is a schematic diagram of the folding electronic device of FIG. 1A in another state. 4B is a partial side view of the folding electronic device of FIG. 4A. Please refer to FIG. 1A and FIG. 4A first. Based on the arrangement of the shaft assembly 140, the first body 110 and the second body 120 can be rotated from the folded state (as shown in FIG. 1A) and unfolded state (as shown in FIG. 4A) by the shaft assembly 140. Switch between. In the expanded state, the aforementioned path L1 changes to be a straight line.

Next, please refer to FIG. 1B, FIG. 2A and FIG. 4B again. It is worth noting that in the connecting rods 143 of the rotating shaft assembly 140, one end of each connecting rod 143 is pivotally connected to the central position of the rotating shaft 142, and each connecting rod The other end of 143 is an eccentric position pivotally connected to the rotating shaft 142, wherein the eccentric position is different from the central position, and the axis of each rotating shaft 142 passes through the central position. Further, the rotating shaft assembly 140 achieves the difference between the eccentric position and the center position by the cam 144. In other words, these cams 144 are substantially provided on the rotating shaft 142 and rotate simultaneously with the rotating shaft 142 taking the above center position as its rotating shaft, that is, the axis of the rotating shaft 142 is also the rotating axis of the cam 144. Furthermore, the cam 144 has an eccentric position different from the center position, and the link 143 is pivotally connected in the eccentric position. For the sliding assembly 130 and the first body 110, and also have another rotating shaft and another cam, as shown in FIG. 2A, the first body 110 has an extension shaft portion 111 and the above-mentioned extension shaft portion 131e, and the extension shaft The portion 111 and the extension shaft portion 131e also have a structure similar to the rotating shaft 142, and as shown in FIG. 1B or FIG. 4B, at the same time, each is equipped with a cam 144, and then forms a pivotal relationship with the links A1, A2, and the links A1, A2 are also It is pivotally connected to the eccentric position of the cam 144.

As a result, the rotating shaft assembly 140 will have an eccentric rotating motion, that is, during the relative rotation from the folded state of FIG. 1B to the unfolding state of FIG. 4B, the rotating shaft assembly 140 is generated along the path due to the eccentric rotating motion The relative displacement of L1, and the relative displacement is used to compensate for the difference in the length of the rotation displacement of the shaft assembly 140 (which can also be regarded as an eccentric link mechanism).

At the same time, please refer to FIG. 1A again, the folding electronic device 100 further includes a limiting component, which is composed of limiting members 161 and 162, wherein the limiting member 161 is disposed on the first body 110, and the limiting member 162 is disposed on the first The two bodies 120, and the limiting component are used to allow the first body 110 and the second body 120 to be combined with each other in a folded state without being easily separated. For example, the limiting component is, for example, a magnetic member/permeable member that can magnetically attract each other or a magnetic member that can magnetically attract each other, or a latch structure that can be latched with each other, so that the first body 110 The second body 120 is maintained in a folded state, and the second body 120 is not moved away from the sliding component 130. As the configuration of the torsion spring 134 described above, the constant driving of the second body 120 and the sliding member 131 are relatively separated. Therefore, when the folding electronic device 100 is to be converted into the unfolded state, the user needs to apply force to the first body 110 or/and The second body 120 releases the limiting capability of the limiting component, and then, the torsion spring 134 can drive the cylinder 121a to move toward the negative Y axis to move the second body 120 and the slider 131 relatively away, so that the second body 120 is substantially relatively away from the first body 110. Here, the relative displacement of the sliding member 131 and the second body 120 is used to compensate for the difference in size of the flexible screen 150 when it is switched from the folded state to the unfolded state. According to this, while the first body 110 and the second body 120 are in a state transition by the shaft assembly 140, in addition to the above-mentioned eccentric rotation movement to move the sliding assembly 130 away from the second body 120, it is more important to The torsion spring 134 is driven to achieve the effect that the sliding assembly 130 and the second body 120 are away from each other.

FIG. 5 illustrates a partial cross-sectional view of the folding electronic device of FIG. 4A from another perspective. Please refer to FIGS. 3 and 5 at the same time. It can be clearly seen that the rotational eccentric motion of the rotating shaft assembly 140 and the driving force of the torsion spring 134 are the main reasons for the sliding assembly 130 and the second body 120 to move away from each other. During this process, the displacement of the sliding component 130 relative to the second body 120 is due to the difference in size between the folded screen 150 and the unfolded flattened state of the flexible screen 150. Here, in the folded state, the path L1 of the rotating shaft assembly 140 is bent, and the flexible screen 150 is located outside the first body 110 and the second body 120. That is, as shown in FIG. A body 110, a shaft assembly 140, a second body 120 and a sliding assembly 130 cover. Conversely, in the unfolded state, the path L1 of the rotating shaft assembly 140 is linear, and the flexible screen 150 is located on the same side of the first body 110, the second body 120, the rotating shaft assembly 140, and the sliding element 130, thereby ensuring the flexible screen 150 In a state of flattening.

In summary, in the above-mentioned embodiment of the present invention, the sliding component and the second body are provided correspondingly, and the rotating shaft component is pivotally connected between the sliding component and the first body, so it is a folding electronic device During the transition of the body from the folded state to the unfolded state, the rotating shaft assembly and the sliding assembly can drive the second body and the first body to produce relative displacement, that is, to move away from each other to stretch the first body and the second body The relative distance, and thus the relative distance of the stretching, can correspondingly compensate for the difference in the length of the sliding component from the arc to the straight line, and compensate for the change in the size (length) of the flexible screen during the process.

In this way, by the relative displacement of the above-mentioned components, the motion consistency between the flexible screen and the first body and the second body is maintained, that is, the flexible screen and the first body and the second body are not moved relative to each other In the case of interference, it can avoid the situation that the flexible screen that should be flattened will still be deformed or wrinkled due to the dimensional changes caused by bending and unfolding.
