The second axis is disposed on the second body, and the third axis is disposed on the first body. Both the second axis and the third axis are located on the back side relative to the flexible screen. When the second body unfolds from a folded state to a first angle position relative to the first body, the rotation limiting mechanism causes the second body to rotate with the second axis. When the second body unfolds from the first angle position to a second angle position relative to the first body, the rotation limiting mechanism causes the second body and the second axis to rotate together around the third axis.

[0010] In one possible implementation, the outer diameter D1 of the first shaft is greater than the outer diameter D2 of the second shaft, and / or, the outer diameter D1 of the first shaft is greater than the outer diameter D3 of the third shaft.

[0024] The support member has a first stop and a second stop;

[0025] When the switching member is disengaged from the first radial groove and engaged with the second radial groove, it is in the first state. In the first state, the first stop portion is limited to rotating within the first circumferential groove. When the switching member is engaged with the first radial groove and disengaged from the second radial groove, it is in the second state.

Detailed Implementation

[0042] In the following description, numerous details are provided to enable a thorough understanding of this disclosure. However, those skilled in the art will appreciate that the following description merely illustrates alternative embodiments of this disclosure by way of example, and that this disclosure can be implemented without one or more of these details. Furthermore, to avoid confusion with this disclosure, some technical features well-known in the art have not been described in detail.

[0043] The following combination Figures 1 to 11 The electronic devices described in the embodiments of this disclosure will be described in detail.

[0044] like Figure 1 and Figure 2 As shown, the electronic device includes a first body 10, a second body 20, a connecting device 30, and a flexible screen 40. The connecting device 30 connects the first body 10 and the second body 20, enabling the second body 20 and the first body 10 to be folded together (e.g., ...). Figure 1As shown, at this time, the second body 20 and the first body 10 are in a folded state (i.e., the electronic device is in a folded state) or unfolded (e.g. Figure 2 As shown, at this time, the second body 20 and the first body 10 are in an unfolded state (i.e., the electronic device is in an unfolded state), see reference. Figure 10 and Figure 11 The flexible screen 40 covers the first body 10 and the second body 20, and has a display side 401 and a back side 402 opposite to the display side 401. The display side 401 is the side of the electronic device that faces the user when in use.

[0045] In the embodiments disclosed herein, the structure of the electronic device is not limited. For example, the electronic device may be an all-in-one computer, a television, or a laptop computer.

[0046] In the embodiments of this disclosure, the structure of the first body 10 is not limited. For example, the first body 10 can be a block structure, or it can be a plate structure. Alternatively, the first body 10 can be a support structure with a base. Based on the base, the first body 10 allows the electronic device to be placed on a supporting surface, which can be a desktop or the ground. The structure of the second body 20 is not limited. For example, the second body 20 can be a block structure, or it can be a plate structure.

[0047] The following will take a laptop computer as an example to describe the connection device 30 in detail. It should be understood that the structure of the connection device 30 is the same as that of a laptop computer for electronic devices such as all-in-one computers and televisions, so it will not be described in detail here.

[0048] As an example, such as Figure 1 and Figure 2 As shown, the first body 10 is located at the keyboard end of the laptop, and the second body 20 is located at the screen end of the laptop. Here, the connecting device 30 enables the electronic device to open and close between a folded state and an unfolded state. Here, the first body 10 can be the D-shell of the laptop, and the second body 20 can be the A-shell of the laptop.

[0049] like Figure 3 As shown, in one embodiment of this disclosure, the connecting device 30 includes a first shaft 31, a second shaft 32, a third shaft 33, and a rotation limiting mechanism 34 (the rotation limiting mechanism 34 can be seen in...). Figure 6A first axis 31 is disposed on the first body 10 and abuts against the display surface side 401 of the flexible screen 40. The first axis 31 may be supported on the first body 10 by a support frame (not shown in the figure), forming a gap between the first body 10 and the first body 10 for the flexible screen 40 to pass through. A second axis 32 is disposed on the second body 20 and has a first rotation center. A third axis 33 is disposed on the first body 10 and has a second rotation center. Both the second axis 32 and the third axis 33 are located on the back side 402 relative to the flexible screen 40. Here, the second axis 32 and the third axis 33 are arranged side by side with intervals and satisfy the parallel condition. The parallel condition here means that the second axis 32 and the third axis 33 are parallel to each other within the tolerance range.

[0050] See also Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In one embodiment of the present disclosure, the connecting device 30, the second axis 32 and the third axis 33 can be alternately locked and rotated by a rotation limiting mechanism 34, so that the electronic device opens and closes along a specified trajectory. Taking the unfolding of the electronic device as an example, the rotational division of the second axis 32 and the third axis 33 and the opening and closing state of the electronic device are as follows:

[0051] 1. In the initial 0-degree state, the angle between the first body 10 and the second body 20 is 0 degrees, that is, the electronic device is in a folded state. The second body 20 is fixed to the second shaft 32 through the connecting plate 36, and the second shaft 32 can rotate around the first rotation center (e.g., Figure 3 ).

[0052] 2. With the electronic device in its initial 0-degree state, rotate it by a first specified angle (e.g., 75 degrees). During the rotation from 0 degrees to 75 degrees, the second body 20 rotates 75 degrees around the first rotation center (e.g., ...). Figure 4 ).

[0053] 3. When the electronic device is in the first angle (open 75 degrees) state, the second axis 32 is restricted from rotating around the first rotation center.

[0054] 4. When the electronic device is in the first angle (open 75 degrees) state, and then rotates to the second specified angle (e.g., 60 degrees), during the rotation from 75 degrees to 135 degrees, the second body 20 and the second shaft 32 together rotate 60 degrees around the second rotation center (e.g., ...). Figure 5 ).

[0055] Here, the second axis 32 and the third axis 33 can be two axes on a dual-axis hinge. Unlike commonly used dual-axis hinges, the connecting device 30 in this embodiment also has a first axis 31 and a rotation limiting mechanism 34 (the rotation limiting mechanism 34 can adopt a commonly used cam-slider structure or the structure described later). When the second body 20 unfolds from the folded state to the first angle position relative to the first body 10, the rotation limiting mechanism 34 causes the second body 20 to rotate with the second axis 32. When the second body 20 unfolds from the first angle position to the second angle position relative to the first body 10, the rotation limiting mechanism 34 causes the second body 20 to rotate around the third axis 33. In this way, the first axis 31 abuts against the flexible screen 40, and the second axis 32 and the third axis 33 cause the device to move along a predetermined trajectory during the opening process, preventing the flexible screen 40 from deforming abnormally during the opening process.

[0056] It should be noted that the above angle positions are for illustrative purposes only. In actual applications, the rotation switching position can be adjusted according to actual needs, but the rotation method and switching principle are basically the same, so we will not go into details here.

[0057] In order to avoid interference between each axis and the flexible screen 40 during the opening process of the electronic device from the first angle position to the second angle position, causing the screen to be lifted, in one embodiment of this disclosure, the outer diameter D1 of the first axis 31 is greater than the outer diameter D2 of the second axis 32, and / or, the outer diameter D1 of the first axis 31 is greater than the outer diameter D3 of the third axis 33.

[0058] Furthermore, in one embodiment of this disclosure, the outer diameter D2 of the second shaft 32 is smaller than the outer diameter D3 of the third shaft 33.

[0059] To ensure that the electronic device can be perfectly closed, in one embodiment of this disclosure, when the second body 20 is in a folded state relative to the first body 10, the flexible screen 40 has a bending radius R. The relationship between the outer diameter D1 of the first shaft 31 and the bending radius R of the flexible screen 40 is: D1 = 2R. It should be understood that this is not an absolute two-fold relationship, and a certain error is allowed. In other words, within the tolerance range, the outer diameter D1 of the first shaft 31 and the bending radius R of the flexible screen 40 satisfy a two-fold relationship.

[0060] See also Figure 3 and Figure 10 As shown, the second axis 32 has a proximal portion 323 near the third axis 33. When the second body 20 is folded relative to the first body 10, the back side 402 of the flexible screen 40 is tangent to the proximal portion 323 of the second axis 32. This further ensures that the electronic device can be perfectly closed.

[0061] In order to avoid increasing the overall thickness of the electronic device, the third axis 33 has a bottom 333 that is away from the second axis 32, and the first body 10 is tangent to the bottom 333.

[0062] like Figure 11 As shown, the second body 20 unfolds relative to the first body 10 to a first angular position (e.g., Figure 11 When the β angle position is reached, the angle between the common tangent of the second axis 32 and the third axis 33 and the first body 10 is equal to the first angle. This ensures that the electronic device can move along the desired trajectory without abnormalities during any process from the folded state to the open state.

[0063] See also Figure 3 , Figure 6 and Figure 7 In one embodiment of this disclosure, the connecting device 30 and the rotation limiting mechanism 34 include a first wheel 341, a second wheel 342, a switching member 343, and a support member 344. The first wheel 341 is mounted on a second shaft 32 and remains relatively fixed to the second shaft 32. The second shaft 32 includes a first shaft body 321 and a first sleeve 322. Both the first wheel 341 and the first sleeve 322 are fitted onto the first shaft body 321. The outer diameter D2 of the second shaft 32 corresponds to the diameter of the first sleeve 322. The second wheel 342 is mounted on a third shaft 33 and remains relatively fixed to the third shaft 33. The third shaft 33 includes a second shaft body 331 and a second sleeve 332. Both the second wheel 342 and the second sleeve 332 are fitted onto the second shaft body 331. The outer diameter D3 of the third shaft 33 corresponds to the diameter of the second sleeve 332. A switching element 343 is disposed between the first wheel 341 and the second wheel 342, and is movable between the two. A support element 344 has its first end connected to the second shaft 32 and its second end connected to the third shaft 33. The support element 344 supports the second and third shafts 32 and 33 to maintain their parallel arrangement, and also limits the rotation angle during the opening of the electronic device. Through the cooperation of the first wheel 341, the second wheel 342, the switching element 343, and the support element 344, the switching element 343 has a first state and a second state. In the first state, the switching element 343 supports the second shaft 32 to rotate by a first angle. In the second state, the switching element 343 supports the second shaft 32 to rotate by a second angle around the third shaft 33 along with the support element 344.

[0064] Here, the first wheel 341 has a first circumferential groove 3411 and a first radial groove 3412, the second wheel 342 has a second circumferential groove 3421 and a second radial groove 3422, and the support member 344 has a first stop portion 3441 and a second stop portion 3442. When the switching member 343 is disengaged from the first radial groove 3412 and engaged with the second radial groove 3422, it is in a first state. In the first state, the first stop portion 3441 is limited to rotating within the first circumferential groove 3411. When the switching member 343 is engaged with the first radial groove 3412 and disengaged from the second radial groove 3422, it is in a second state. In the second state, the second stop portion 3442 is limited to rotating within the second circumferential groove 3421.

[0065] In one embodiment of this disclosure, the connecting device 30 and the rotation limiting mechanism 34 further include a blocking member 345. The first end of the blocking member 345 is connected to the second shaft 32, and the second end is connected to the third shaft 33. The blocking member 345 supports the second shaft 32 and the third shaft 33 to maintain their parallel arrangement. It also works with the support member 344 to axially limit the switching member 343. To achieve this axial limitation, the support member 344 is provided with a limiting groove 3443, and the blocking member 345 is provided with a blocking groove (not shown in the figure) corresponding to the limiting groove 3443. The limiting groove 3443 and the blocking groove form a guide space, confining the switching member 343 within this guide space. The switching member 343 can move along the guide space towards the second shaft 32 or towards the third shaft 33, enabling it to achieve state switching.

[0066] Here, the connecting device 30 can also be combined with a torque assembly to maintain the parallel arrangement between the second shaft 32 and the third shaft 33. The torque assembly can be a combination of a torsion spring and a nut, which will not be described in detail here.

[0067] During the process of unfolding the second body 20 relative to the first body 10 from a folded state to a second angular position, the operating principle of the connecting device 30 is as follows: When the second body 20 is in a folded state relative to the first body 10, the first end of the switching member 343 disengages from the first radial groove 3412, and the second end engages with the second radial groove 3422. The second shaft 32 can rotate, while the third shaft 33 cannot rotate. Thus, when unfolding the electronic device, the second body 20 can rotate around the first rotation center. During this process, the first wheel 341 rotates relative to the support member 344, and the rotation angle is limited by the first stop 3441 and the first circumferential groove 3411. When unfolded to the first angular position, the first end of the switching member 343 engages with the first radial groove 3422. When the switch 343 is engaged, the second end of the switch 343 disengages from the second radial groove 3422. At this time, the first wheel 341 rotates to the edge of the first stop 3441 and the first circumferential groove 3411 and can no longer rotate. When the electronic device continues to be deployed, the rotation of the first wheel 341 is restricted due to the engagement. The first wheel 341 and the support member 344 cannot rotate with each other due to the engagement between the first stop 3441 and the edge of the first circumferential groove 3411. Thus, the second body 20 will rotate around the third axis 33 together with the second shaft 32 and the support member 344. During this process, the support member 344 rotates relative to the second wheel 342, and the rotation angle is limited by the second stop 3442 and the second circumferential groove 3421.

[0068] To prevent the second shaft 32, the third shaft 33, and the rotation limiting mechanism 34 from being exposed, the connecting device 30 also includes a shielding member 35, such as... Figure 8 As shown, a first accommodating space 351 and a second accommodating space 352 are respectively formed on the two opposite ends of the shielding member 35. A third shaft 33 is disposed in the first accommodating space 351, and a second shaft 32 is disposed in the second accommodating space 352. Here, the shielding member 35 may include a plate-shaped body. The plate-shaped body is bent at the first end to form an arc-shaped first accommodating space 351, and the third shaft 33 is disposed in the arc-shaped first accommodating space 351. The plate-shaped body is also bent at the second end to form an arc-shaped second accommodating space 352, and the second shaft 32 is disposed in the arc-shaped second accommodating space 352.

[0069] In one embodiment of this disclosure, the connecting device 30 further includes a connecting plate 36, such as... Figure 9 As shown, the connecting plate 36 is fixed on the second body 20, and the connecting plate 36 has a cylindrical hinge portion 361. The cylindrical hinge portion 361 is fixedly connected to the second shaft 32. The outer diameter of the cylindrical hinge portion 361 is equal to the outer diameter D2 of the second shaft 32. In this way, it can further prevent the flexible screen 40 from abnormally deforming in the area of ​​the connecting device 30 and losing the correct movement trajectory during the unfolding or folding of the electronic device.

[0070] In the description of this disclosure, it should be understood that the orientation or positional relationship indicated by directional terms is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this disclosure and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this disclosure; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0071] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," and "above" are used herein to describe the spatial positional relationship between one or more components or features shown in the figures and other components or features. It should be understood that spatial relative terms include not only the orientation of the component as depicted in the figures but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0072] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this disclosure.

[0073] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in sequences other than those illustrated or described herein.

[0074] This disclosure has been described through the above embodiments; however, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit this disclosure to the described embodiments. Furthermore, those skilled in the art will understand that this disclosure is not limited to the above embodiments, and many more variations and modifications can be made based on the teachings of this disclosure, all of which fall within the scope of protection claimed by this disclosure.
