[0009] An adjustment device is connected to the display screen, and the adjustment device moves based on a predetermined trajectory to switch the display screen between a flattened state and a curved state.

[0010] in,

[0011] When the adjustment device is in the first position, the display screen is in a flattened state;

[0019] Optionally, in the above-mentioned electronic device, the number of the adjustment devices is at least two, including a first adjustment device and a second adjustment device;

[0020] The first adjustment device and the second adjustment device are symmetrically arranged with respect to the display screen;

[0021] Specifically, by moving the first adjustment device and the second adjustment device relatively far apart, the display screen is switched to the flat state; by moving the first adjustment device and the second adjustment device relatively close together, the display screen is switched to the curved state.

[0022] Optionally, the above-mentioned electronic device further includes a transmission mechanism that drives the first adjustment device and the second adjustment device to move synchronously;

[0023] The transmission mechanism enables the first adjustment device and the second adjustment device to move synchronously closer and further apart.

[0046] This application discloses an electronic device for adjusting the state of a display screen.

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] like Figures 1-8 As shown, this application provides an electronic device including a display screen and an adjustment device. The adjustment device is connected to the display screen and slides along a predetermined trajectory, causing the display screen to switch between a flattened state and a curved state. When the adjustment device is in a first position, the display screen is in a flattened state; when the adjustment device slides along the predetermined trajectory from the first position to a second position, the display screen is relatively curved.

[0049] The electronic device provided in this application embodiment can move between a first position and a second position by sliding an adjustment device along a predetermined trajectory. Furthermore, since the adjustment device is connected to the display screen, it can change the structural state of the display screen. When the adjustment device is in the first position, the display screen is in a flat state; when the adjustment device is in the second position, the display screen is relatively curved. This configuration facilitates adjusting the state of the display screen, allowing it to switch between a flat and curved state. Switching the display screen to a flat state makes it more convenient to carry; while switching it to a curved state during use improves the user experience.

[0050] It should be noted that, in Figure 1 and Figure 2 The image shows two displays: one in a flat state and the other in a bent state.

[0051] By switching between a flattened and a bent state, the display screen can have at least two usage states, allowing users to choose the appropriate state according to their actual needs.

[0052] The electronic device also includes a slide rail arranged along a predetermined trajectory. The adjustment device slides in conjunction with the slide rail. This arrangement guides the adjustment device, allowing it to switch between a first and second position, and consequently, the display screen to switch between a flat and curved state. The slide rail can be a groove or a solid protrusion, with the adjustment device acting as a slider, and the slide rail's structure restricting the sliding direction of the adjustment device.

[0053] In this embodiment, the adjustment device can also be used as a support component for the display screen, which will not be described in detail here and is within the scope of protection.

[0054] Of course, multiple positioning devices capable of positioning the adjustment device can also be arranged along a predetermined trajectory. Among the multiple positioning devices, there is at least a first positioning device that enables the adjustment device to be located in a first position and a second positioning device that enables the adjustment device to be located in a second position. Through the positioning cooperation between the adjustment device and the first positioning device and the positioning cooperation between the adjustment device and the second positioning device, the display screen can be switched between a flattened state and a curved state.

[0055] Specifically, the positioning device can be a groove or an opening, and the adjusting device is a plug-in component that can be inserted into the positioning device. The positioning device can also be a snap-fit ​​structure, which can be used to position and adjust the device. The positioning device can also have other structures, which will not be described in detail here and are all within the scope of protection.

[0056] In embodiments where the adjustment device slides in conjunction with the slide rail, in order to ensure that the display screen can remain in a flat or curved state, the electronic device further includes a first limiting part for positioning the adjustment device in a first position and a second limiting part for positioning the adjustment device in a second position.

[0057] Preferably, the adjusting device can be positioned by engaging with the first limiting part and the second limiting part in a concave-convex fit.

[0058] like Figure 8 As shown, taking the first adjusting device 310 as an example, the first adjusting device 310 slides in conjunction with the first slide rail 330. In this embodiment, both the first limiting part 331 and the second limiting part 332 are groove structures, and the first adjusting device 310 has a protruding structure. The protruding structure of the first adjusting device 310 can engage with the first limiting part 331 and the second limiting part 332 in a concave-convex fit.

[0059] In this embodiment, the protruding structure of the first adjusting device 310 is disposed at the bottom of the first adjusting device 310. Since the first adjusting device 310 has a protruding structure, when the first adjusting device 310 is in a position other than the first position and the second position, the protruding structure contacts the bottom surface of the first slide rail 330, reducing the contact area between the first slide rail 330 and the bottom of the first adjusting device 310, minimizing friction loss, and facilitating the movement of the first adjusting device 310 within the first slide rail 330.

[0060] Alternatively, a groove structure can be provided on the first adjusting device 310, and both the first limiting part 331 and the second limiting part 332 are protruding structures, which can also achieve positioning through the interlocking of concave and convex parts.

[0061] Taking the first limiting part 331 as an example, when the first limiting part 331 is a protruding structure, the first adjusting device 310 has a groove structure that mates with the protruding structure; when the first limiting part 331 is a groove structure, the first adjusting device 310 has a protruding structure that mates with the groove structure. Similarly, taking the second limiting part 332 as an example, when the second limiting part 332 is a protruding structure, the first adjusting device 310 has a groove structure that mates with the protruding structure; when the second limiting part 332 is a groove structure, the first adjusting device 310 has a protruding structure that mates with the groove structure.

[0062] The adjustment device includes a sliding part that slides with a slide rail and a connecting part for connecting to the display screen; the interior of the adjustment device has a channel for cables to pass through, with one end of the channel opening in the sliding part and the other end opening in the connecting part. This design facilitates internal cable routing and prevents cables from rubbing against other components during the switching between bent and flattened states of the display screen. Specifically, in the first embodiment, at least two adjustment devices are used, including a first adjustment device 310 and a second adjustment device 320.

[0063] like Figure 8 As shown, taking the first adjustment device 310 as an example, the first adjustment device 310 includes a first sliding part 311 that slides in conjunction with the first slide rail 330 and a first connecting part 312 for connecting to the display screen; the interior of the first adjustment device 310 has a first channel 313 through which the cable 400 passes, one end of the first channel 313 is located in the first sliding part 311, and the other end of the first channel 313 is located in the first connecting part 312. Therefore, the cable 400 can pass through the first channel 313, and the cable connector of the cable 400 can be connected to the display screen.

[0064] Similarly, the second adjustment device includes a second sliding part that slides with the second slide rail and a second connecting part for connecting to the display screen; the interior of the second adjustment device has a second channel for cables to pass through, with the two ends of the second channel opening at the second sliding part and the other two ends of the second channel opening at the second connecting part. Therefore, cables can pass through the second channel, and the cable connectors can be connected to the display screen.

[0065] Furthermore, the first adjustment device 310 and the second adjustment device 320 are symmetrically arranged relative to the display screen. Specifically, by moving the first adjustment device 310 and the second adjustment device 320 relatively apart, the display screen switches to a flat state; by moving the first adjustment device 310 and the second adjustment device 320 relatively closer, the display screen switches to a curved state. It can be understood that by adjusting the position of the adjustment devices, the distance between the first adjustment device 310 and the second adjustment device 320 is changed. Specifically, when either the first adjustment device or the second adjustment device slides along a predetermined trajectory, the distance between the first adjustment device and the second adjustment device changes. Since the first adjustment device is connected to the first part of the display screen and the second adjustment device is connected to the second part of the display screen, changing the distance between the first adjustment device and the second adjustment device changes the distance between the first part and the second part of the display screen, thereby enabling the display screen to switch between a flat state and a curved state.

[0066] like Figure 7 As shown, when the display screen is in a flat state (dashed line position in the figure), the distance between the first adjustment device 310a and the second adjustment device 320a is L1; when the display screen is in a curved state (solid line position in the figure), the distance between the first adjustment device 310b and the second adjustment device 320b is L2. Wherein, L1 is greater than L2.

[0067] The first adjustment device 310 and the second adjustment device 320 are symmetrically arranged with respect to the display screen, that is, the first adjustment device 310 and the second adjustment device 320 are symmetrical with respect to the vertical center line of the display screen, so that the first adjustment device 310 and the second adjustment device 320 are symmetrically arranged on both sides of the vertical center line of the display screen. With the above arrangement, when the first adjustment device 310 and the second adjustment device 320 move to the same relative position, the display screen can form a curved screen symmetrical along its center line, further improving the user experience.

[0068] To facilitate the adjustment of the first adjustment device 310 and the second adjustment device 320, thereby achieving symmetrical bending of the display screen to form a curved screen symmetrical along its centerline, the electronic device provided in this embodiment also includes a transmission mechanism that drives the first adjustment device 310 and the second adjustment device 320 to move synchronously. Through the transmission mechanism, synchronous movement of the first adjustment device 310 and the second adjustment device 320 towards each other and away from each other can be achieved. With the above arrangement, the distance between the first adjustment device 310 and the second adjustment device 320 is adjusted to facilitate the adjustment of the display screen's state.

[0069] like Figure 5 As shown, the transmission mechanism includes a transmission gear 350, a first rack 370, and a second rack 380. The transmission gear 350 is rotatable; the first rack 370 meshes with the transmission gear 350, and a first adjusting device 310 is connected to the first rack 370; the second rack 380 is parallel to and symmetrically arranged on both sides of the transmission gear 350, meshes with the transmission gear 350, and a second adjusting device 320 is connected to the second rack 380.

[0070] The rotation of the transmission gear 350 drives the first rack 370 and the second rack 380 to rotate synchronously, thereby driving the first adjusting device 310 and the second adjusting device 320 to move synchronously.

[0071] Alternatively, the transmission mechanism can be configured as a transmission belt, transmission gear set, or linkage structure, as long as it can ensure that the first adjustment device 310 and the second adjustment device 320 can move synchronously.

[0072] In this embodiment, the transmission mechanism has a transmission mechanism housing 300, and the transmission gear 350, the first rack 370 and the second rack 380 are all located inside the transmission mechanism housing 300. The first slide rail 330 and the second slide rail 340 are directly provided on the transmission mechanism housing 300.

[0073] Specifically, the first slide rail 330 and the second slide rail 340 are elongated holes. Taking the first slide rail 330 as an example, the extension direction of the first slide rail 330 is the predetermined trajectory direction of the movement of the first adjusting device 310. The first adjusting device 310 passes through the elongated hole, with one end located inside the transmission mechanism housing 300 connected to the first rack 370, and the other end located outside the transmission mechanism housing 300 connected to the display screen.

[0074] In this embodiment, it is preferable to manually adjust the display screen to switch between a flattened state and a bent state. Therefore, the transmission mechanism also includes a hand-twisting component 360 located outside the transmission mechanism housing 300. The hand-twisting component 360 is connected to the transmission gear 350, and the axis of the hand-twisting component 360 coincides with the axis of the transmission gear 350. The rotation of the hand-twisting component 360 drives the transmission gear 350 to rotate.

[0075] Preferably, the hand-twisting component 360 is provided with a raised strip to facilitate gripping by a hand on both sides of the raised strip. Furthermore, a countersunk hole can be provided on the outside of the transmission mechanism housing 300, into which the hand-twisting component 360 is rotatably positioned.

[0076] Alternatively, a toggle component can be provided, with one end of the toggle component contacting the teeth of the transmission gear 350, and the other end of the toggle component being able to be held by hand, so as to drive the toggle component to move and cause one end of the toggle component to move the teeth of the transmission gear 350, thereby realizing the rotation of the transmission gear 350. In this embodiment, the transmission gear 350 can be rotatably disposed within the transmission mechanism housing 300.

[0077] An electrically adjustable display screen can also be used to switch between flattened and bent states. For example, a rotary drive device such as a motor can be installed, with its drive end connected to the center of the transmission gear 350.

[0078] Alternatively, only one adjustment device can be used to achieve full or partial bending of the display screen. Specifically, the display screen has a first region and a second region, with the second region in a flattened state; the adjustment device is connected to the first region; the adjustment device slides along a predetermined trajectory, allowing the first region to switch between a flattened state and a bent state. In this embodiment, the second region of the display screen can be a non-flexible structure, while only the first region is a flexible structure. To ensure the state adjustment of the first region, the connection point between the first and second regions, or the second region, has a support component that fixes and supports the display screen.

[0079] In this embodiment, the electronic device also includes a first body 200 and a second body 100. The first body 200 includes a display screen. The first body 200 and the second body 100 are rotatably connected to realize the relative folding and relative unfolding of the first body 200 and the second body 100.

[0080] In this embodiment, the first body 200 and the second body 100 are rotatably connected by a rotating shaft.

[0081] Specifically, the transmission mechanism housing 300 is located at the connection between the first body 200 and the second body 100, and the rotating shaft is located at the end of the transmission mechanism housing 300. The transmission components (first rack 370 and second rack 380) inside the transmission mechanism housing 300 are connected to the adjustment device, and the connection between the adjustment device and the display screen is achieved through the connection between the adjustment device and the first body 200. Furthermore, the rotating shaft is rotatably connected to the second body 100, thus achieving a rotatable connection between the first body 200 and the second body 100.

[0082] In this embodiment, since the rotating shaft is located at the end of the transmission mechanism housing 300, the transmission mechanism housing 300 rotates relative to the second body 100. To prevent interference between the protrusion of the hand-twisting component 360 and the second body 100, the second body 100 is provided with a clearance groove to avoid the protrusion. Furthermore, the combination of the protrusion and the clearance groove allows for positioning after the first body 200 and the second body 100 are folded relative to each other, preventing excessive folding of the first body 200 and the second body 100.

[0083] like Figure 8 As shown, the rotating shaft can be a rotating shaft cylinder, i.e., it has a channel inside. A cable 400 connects the second body 100 and the first body 200. One end of the cable 400 is connected to the second body 100, and the other end of the cable 400 (the cable connector of the cable 400) can enter the interior of the transmission mechanism housing 300 through the end of the rotating shaft cylinder away from the transmission mechanism housing 300, and then enter the first channel 313 through the opening at the first sliding part 311, and exit through the opening at the other end of the first channel 313 located at the first connecting part 312. The cable connector of the cable 400 is connected to the first body 200. With the above arrangement, the part of the cable 400 located between the second body 100 and the first body 200 is protected in the channel of the rotating shaft, inside the transmission mechanism housing 300, and in the first channel 313. During the relative rotation of the second body 100 and the first body 200, the friction between this part of the cable 400 and other components is small, avoiding wear of the cable 400 and effectively improving the service life of the cable 400.

[0084] Alternatively, the rotating shaft can be set on the second body 100, and the first body 200 and the second body 100 can be rotated through the rotating shaft and the transmission mechanism housing 300.

[0085] A separate rotating shaft can also be provided to achieve a rotatable connection between the first body 200 and the second body 100. The transmission mechanism and the rotating shaft are independent of each other.

[0086] Of course, the electronic device having the first body 200 and the second body 100 is preferably a laptop computer. Specifically, the first body 200 and the second body 100 can rotate 360°, so that the laptop computer can have at least three states:

[0087] In the first state, the first body 200 and the second body 100 are folded relative to each other, with the side of the first body 200 having a display screen facing the side of the second body 100 having an operation panel (keyboard and touchpad).

[0088] In the second state, the first body 200 and the second body 100 are folded relative to each other, with the side of the first body 200 having a display screen facing away from the side of the second body 100 having an operation panel (keyboard and touchpad).

[0089] In the third state, the first body 200 and the second body 100 unfold relative to each other.

[0090] Preferably, the display screen is adjusted to a curved state in the third state. In the first and second states, the display screen is preferably flattened. This arrangement facilitates portability of the electronic device in the first state, making it easy to carry and reducing its footprint. Furthermore, it facilitates use as a tablet in the second state, reducing the size required for hand grip and improving user convenience. Of course, the display screen can also be curved in the second state, but this will not be specifically described here. Additionally, the third state improves user comfort.

[0091] When the electronic device is a desktop computer or a standalone display device, the electronic device can have a support structure, and the support structure has a matching structure, so that the adjustment device can move along a predetermined trajectory.

[0092] The first body 200 also includes a housing 210 for supporting the display screen; the housing 210 includes a plurality of sub-housings that are hinged in sequence, the plurality of sub-housings are arranged along the bendable edge direction of the display screen and connected to the display screen; by changing the connection angle between two adjacent sub-housings, the bending and flattening operations of the display screen and its corresponding connected area are realized.

[0093] like Figure 4 and Figure 5 As shown, to achieve the bending effect, preferably, the sub-shells near the middle region of the housing (middle sub-shell 212) have a smaller width, while the sub-shells near the edge region of the housing (first sub-shell 211 and second sub-shell 213) have a larger width. The width direction of the sub-shells is the arrangement direction of the multiple sub-shells. The length direction of the sub-shells is perpendicular to the width direction. The adjustment device is preferably located at one end edge of the sub-shell along its length direction.

[0094] In embodiments where there are at least two adjusting devices (such as a first adjusting device 310 and a second adjusting device 320), one adjusting device is connected to one sub-housing. That is, the first adjusting device is connected to one sub-housing, and the second adjusting device is connected to another sub-housing.

[0095] like Figure 4 , Figure 5 and Figure 6As shown, the housing includes a first sub-housing 211, an intermediate sub-housing 212, and a second sub-housing 213 arranged sequentially. The number of intermediate sub-housing 212 can be multiple (e.g., four or six), and adjacent sub-housings are hinged together. A first adjusting device 310 is connected to the first sub-housing 211, and a second adjusting device 320 is connected to the second sub-housing 213. Movement of the adjusting devices causes the first sub-housing 211 and the second sub-housing 213 to move, and also causes the multiple intermediate sub-housing 212 to move relative to each other.

[0096] When the first adjustment device 310 and the second adjustment device 320 are relatively far apart, the housing composed of multiple sub-housings flattens out. The side of the multiple sub-housings facing the display screen is located in the same plane, which effectively supports the display screen, so that the display screen switches to the flattened state.

[0097] When the first adjusting device 310 and the second adjusting device 320 are close to each other, the housing composed of multiple sub-housings bends. The side of the multiple sub-housings facing the display screen forms a bending surface composed of multiple planes, which supports the bent display screen and allows the display screen to switch to the bent state. When the display screen bends to form a smooth transition arc surface, the display screen is preferably partially connected to the sub-housing. Alternatively, the display screen can be bent to form a bending surface composed of multiple plane segments.

[0098] Of course, the housing can also have other structures. In another embodiment, the housing includes a winding plate and an elastic reset member connected to the back of the winding plate, the winding plate flattening under the restoring force of the elastic reset member. The display screen is connected to the winding plate or the display screen serves as the winding plate. With the above configuration, the reset and flattening function of the display screen can be achieved. The adjustment device only needs to be positioned when the display screen is bent.

[0099] like Figure 4 and Figure 5 As shown, adjacent sub-shells are hinged together by a connecting piece 214. The connecting piece 214 has two connecting holes, located at its ends. One end of the connecting piece 214 is embedded in one of the adjacent sub-shells, and the other end is embedded in the other. Each sub-shell has a long-length opening aligned with the connecting hole on the connecting piece 214. A connecting shaft or pin passes through the opening and connecting hole, thus achieving the hinge between the sub-shell and the connecting piece 214, and consequently, the hinge between the two adjacent sub-shells. The number of connecting pieces 214 can be multiple or a single piece, depending on the specific requirements.

[0100] Of course, other structures are also possible. For example, a hinged connector can be provided on the side of two adjacent sub-shells facing away from the display screen. This hinged connector may include a first connecting rod hinged to one of the two adjacent sub-shells; a second connecting rod hinged to the other of the two adjacent sub-shells; and a hinged connecting shaft hinged between the first and second connecting rods. Specifically, the hinged connecting shaft may be a connecting tube, and the inner hole of the connecting tube may be a channel for cables to pass through.

[0101] Specifically, the hinged connector further includes: a first auxiliary rod hinged at one end to one of the two adjacent sub-shells, the other end of which is hinged to a second connecting rod; and a second auxiliary rod hinged at one end to the other of the two adjacent sub-shells, the other end of which is hinged to the first connecting rod. The addition of auxiliary rods improves the stability of the hinged connector.

[0102] Two adjacent sub-shells can also be connected by hinges or similar components, which will not be specifically described here and are all within the scope of protection.

[0103] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0104] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
