Description

Folding electronic device

Technical Field

The present invention relates to an electronic device, and more particularly, to a foldable electronic device.

Background

As technology is continuously advanced, a foldable electronic device using a flexible screen is becoming a future development trend, and in such a device, for example, a smart phone, a flexible screen is usually disposed on two bodies, and when the two bodies are rotated relatively by a rotating shaft to be folded or unfolded, the flexible screen can be switched between a folded state and an unfolded and flattened state.

However, when the flexible screen is bent, the inner and outer circumferential lengths of the bent portion of the flexible screen change, and therefore the change needs to be considered when designing the mechanism of the rotating shaft, so as to prevent the flexible screen from being damaged during the bending or unfolding process.

SUMMERY OF THE UTILITY MODEL

The utility model provides a folding electronic device, which provides the length difference of the flexible screen compensated by the mechanism in the status switching process of bending and unfolding the flexible screen, so as to make the process act smoothly and avoid the damage of the flexible screen.

The utility model discloses a foldable electronic device, including first organism, pivot subassembly, second organism, sliding assembly and flexible screen. The rotating shaft assembly is pivoted between the first machine body and the sliding assembly. The sliding assembly is slidably coupled to the second body. The flexible screen is disposed on the first body and the second body. The first body and the second body are switched between an unfolded state and a folded state by the rotating shaft assembly. In the process of converting from the folded state to the unfolded state, the rotating shaft assembly and the sliding assembly drive the first machine body and the second machine body to generate relative displacement so as to compensate the length difference of the flexible screen between the folded state and the unfolded state.

Based on the above, by the corresponding arrangement of the sliding component and the second body, and the rotating shaft component is pivoted between the sliding component and the first body, when the foldable electronic device is converted 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 generate relative displacement, that is, the second body is moved away from the sliding component and the rotating shaft component, so as to stretch the relative distance between the first body and the second body, and further enable the stretched relative distance to be changed in response to the size (length) of the flexible screen in the process of converting from the folded state to the unfolded state.

Therefore, the flexible screen and the first and second bodies are kept consistent in movement by the relative displacement of the members, that is, the flexible screen and the first and second bodies are not interfered in movement, so that the flexible screen can be prevented from being deformed and folded even if the flexible screen is in a flat state due to size change caused by bending and unfolding.

In order to make the aforementioned and other features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Detailed Description

Fig. 1A is a schematic view of a foldable electronic device according to an embodiment of the present invention. Fig. 1B is a partial side view of the folding electronic device of fig. 1A. Fig. 2A is an exploded view of the folding electronic device of fig. 1A. Referring to fig. 1A, fig. 1B and fig. 2A, in the present embodiment, the foldable electronic device 100 includes a first body 110, a rotating shaft assembly 140, a second body 120, a sliding assembly 130 and a flexible screen 150. The rotating shaft assembly 140 is pivotally connected between the first body 110 and the sliding assembly 130. The sliding assembly 130 is slidably coupled to the second body 120. The flexible screen 150 is disposed on the first body 110 and the second body 120. The first body 110 and the second body 120 are switched between an unfolded state and a folded state by the rotation shaft assembly 140.

Further, the flexible screen 150 includes a first region S1, a second region S2, and a third region S3, wherein the first region S1 is disposed on the surface S4 of the second body 120, the second region S2 is disposed on the surface S5 of the first body 110, and the third region S3 is connected between the first region S1 and the second region S2 and corresponds to the spindle assembly 140.

Referring to fig. 1B and fig. 2A, in the present embodiment, the rotating shaft assembly 140 includes a plurality of torsion members 141, a plurality of rotating shafts 142 and a plurality of connecting rods 143, wherein the torsion members 141 are arranged between the first body 110 and the second body 120 along a path L1, the rotating shafts 142 respectively penetrate through the torsion members 141 and are parallel to each other (parallel to the X axis), and the connecting rods 143 are correspondingly pivoted to the rotating shafts 142, the first body 110 or the sliding assembly 130.

In detail, the connecting rods 143 are pivotally connected to the rotating shafts 142 at intervals, as shown in fig. 1B and fig. 2A, except that the connecting rod a1 is pivotally connected to the sliding assembly 130 and the rotating shaft 142 adjacent to the sliding assembly 130, and except that the connecting rod a2 is pivotally connected to the first body 110 and the rotating shaft 142 adjacent to the first body 110, the remaining connecting rods 143 are respectively pivotally connected between two adjacent rotating shafts 142, and as shown in fig. 2A, the connecting rods 143 are arranged in a left-right interval staggered manner on a path L1 arranged along the torsion member 141 and the rotating shaft 142. For example, in fig. 2A, if the path L1 is regarded as being on the Y-Z plane, the links 143 are staggered left and right to represent that the partial links 143 are located in the right negative X-axis space and the partial links 143 are located in the left positive X-axis space, when the viewing angle is from left to right (toward the negative Y-axis). Here, the foldable electronic device 100 of fig. 1A, 1B and 2A is substantially in a folded state.

Fig. 3 is a partial cross-sectional view of the foldable electronic device of fig. 1A from another perspective. Referring to fig. 2A, fig. 2B and fig. 3, in the present embodiment, the second body 120 is composed of

components

121 and 122, the sliding assembly 130 includes a sliding member 131 and a locking accessory 133, the sliding member 131 has a track 131d, and the connecting rod a1 of the rotating shaft assembly 140 is pivotally connected to the extending shaft portion 131e of the sliding member 131. The locking member 133 is locked to the cylinder 121a at the inner surface of the member 121 through the rail 131d, so that the sliding member 131 can slide relative to the second body 120 by the locking member 133 being movably fitted to the rail 131 d.

Further, the sliding member 131 has a first portion 131a and a second portion 131b, the link a1 of the spindle assembly 140 is pivotally connected to the extending shaft 131e on the first portion 131a, the second portion 131b extends from the first portion 131a toward the second body 120, and the second portion 131b has the track 131 d. Furthermore, the sliding assembly 130 further includes a torsion spring 134, one end of which is disposed on the second portion 131b and the other end of which is connected between the second portion 131b of the sliding member 131 and the locking attachment 133, and which is also equivalent to the cylinder 121a and the locking attachment 133 connected to the member 121, and can be regarded as being connected between the second body 120 and the sliding assembly 130. In this embodiment, the torsion spring 134 constantly drives the locking accessory 133 (and the cylinder 121a) to move toward one end of the rail 131d, which is substantially away from the pivot of the link A1 and the extending shaft 131 e. In other words, the torsion spring 134 of the present embodiment is substantially used for pushing the sliding member 131 and the second body 120 away from each other.

In addition, the sliding assembly 130 further includes a coupling member 132 disposed in the second body 120, wherein the sliding member 131 further has a guide post 131c extending toward the second body 120, and the coupling member 132 has a corresponding guide hole 132a, and the guide post 131c is movably disposed through the guide hole 132a of the coupling member 132, so as to ensure that the sliding member 131 can smoothly move relative to the second body 120 along the Y-axis.

Fig. 4A is a schematic diagram illustrating the foldable electronic device of fig. 1A in another state. Fig. 4B is a partial side view of the folding electronic device of fig. 4A. Referring to fig. 1A and fig. 4A, based on the arrangement of the rotating shaft assembly 140, the first body 110 and the second body 120 can be switched between a folded state (as shown in fig. 1A) and an unfolded state (as shown in fig. 4A) by the rotating shaft assembly 140. In the unfolded state, the path L1 is changed to be a straight line.

Referring to fig. 1B, fig. 2A and fig. 4B, it is noted that, in the connecting rods 143 of the rotating shaft assembly 140, one end of each connecting rod 143 is pivoted to a central position of the rotating shaft 142, and the other end of each connecting rod 143 is pivoted to an eccentric position of the rotating shaft 142, wherein the eccentric position is different from the central position, and an axis of each rotating shaft 142 passes through the central position. Further, the rotating shaft assembly 140 is driven by the cam 144 to achieve the difference between the eccentric position and the central position. That is, the cams 144 are substantially disposed on the rotating shaft 142 and rotate simultaneously with the rotating shaft 142 and the rotating shaft 142 at the above-mentioned central position, i.e., the axis of the rotating shaft 142 is also the rotation axis of the cams 144. Furthermore, the cam 144 has an eccentric position different from the central position, so that the link 143 is pivoted at the eccentric position. As shown in fig. 2A, the first body 110 has an extending shaft 111 and an extending shaft 131e, and the extending shaft 111 and the extending shaft 131e have structures similar to the rotating shaft 142, and as shown in fig. 1B or fig. 4B, the first body 110 and the cam 144 are respectively engaged to form a pivot connection with the links a1 and a2, and the links a1 and a2 are pivoted at an eccentric position of the cam 144.

In this way, the rotating shaft assembly 140 generates an eccentric rotating motion, that is, during the relative rotation from the folded state shown in fig. 1B to the unfolded state shown in fig. 4B, the rotating shaft assembly 140 generates a relative displacement along the path L1 due to the eccentric rotating motion, and the relative displacement is used to compensate the length difference of the self rotating displacement of the rotating shaft assembly 140 (which can also be regarded as an eccentric link mechanism).

Meanwhile, referring to fig. 1A, the foldable electronic device 100 further includes a limiting component, which is composed of limiting

parts

161 and 162, wherein the limiting part 161 is disposed on the first body 110, the limiting part 162 is disposed on the second body 120, and the limiting component is used to enable the first body 110 and the second body 120 to be combined with each other and not easily separated when folded. For example, the position-limiting component is, for example, a magnetic component/magnetic-conductive component that can be magnetically attracted to each other or a magnetic component that can be magnetically attracted to each other, or can be a latch (latch) structure that can be fastened to each other, so as to maintain the first body 110 and the second body 120 in the folded state, and also to keep the second body 120 from moving away from the sliding component 130. As the aforementioned configuration of the torsion spring 134, the second body 120 and the sliding member 131 are constantly driven to be separated from each other, so when the foldable electronic device 100 is to be converted into the unfolded state, a user needs to apply a force to the first body 110 or/and the second body 120 to release 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 relatively move the second body 120 and the sliding member 131 away from each other, so that the second body 120 is substantially relatively far away from the first body 110. Here, the relative movement distance between the sliding member 131 and the second body 120 is used to compensate the size difference of the flexible screen 150 from the folded state to the unfolded state. Accordingly, when the first body 110 and the second body 120 perform state conversion through the rotating shaft element 140, in addition to the above-mentioned moving the sliding element 130 away from the second body 120 through the eccentric rotation motion, what is more important is to achieve the effect of moving the sliding element 130 and the second body 120 away from each other through the driving of the torsion spring 134.

Fig. 5 is a partial cross-sectional view of the foldable electronic device of fig. 4A from another perspective. As can be clearly understood by referring to fig. 3 and fig. 5, the eccentric rotation 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. In the process, the displacement of the sliding element 130 relative to the second body 120 is generated in response to the size difference between the folded state and the unfolded 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. 1A, the flexible screen 150 covers the first body 110, the rotating shaft assembly 140, the second body 120, and the sliding assembly 130. 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 assembly 130, thereby ensuring that the flexible screen 150 is in the flat state.

In summary, in the above embodiments of the present invention, the sliding element and the second body are correspondingly disposed, and the rotating shaft element is pivotally connected between the sliding element and the first body, so that when the foldable electronic device is converted from the folded state to the unfolded state, the rotating shaft element and the sliding element can drive the second body and the first body to generate relative displacement, that is, move away from each other to stretch the relative distance between the first body and the second body, so that the stretched relative distance can correspondingly compensate the length difference of the sliding element from the arc-shaped straight line, and compensate the size (length) change of the flexible screen in the process.

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.
