Description

Technical Field

[0001] This application belongs to the field of foldable electronic device technology, and specifically relates to an electronic device. Background Technology

[0002] As people's demand for electronic devices increases, foldable electronic devices are gradually being promoted and used.

[0003] Foldable electronic devices can switch between large and small screens to meet users' needs in different scenarios. However, frequent folding can affect the lifespan of the display, causing creases or even breakage. Summary of the Invention

[0004] This application aims to provide an electronic device with a resizable screen, which at least solves the problem of damage to the display caused by frequent folding of the foldable screen.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides an electronic device, including:

[0007] substrate;

[0008] A first housing and a second housing, the first housing and / or the second housing being slidably connected to the substrate, so that the electronic device can switch between an extended state and a retracted state;

[0009] The first rotating shaft and the second rotating shaft are respectively disposed in the first housing and the second housing, with the first rotating shaft rotatably connected to the first housing and / or the second rotating shaft rotatably connected to the second housing;

[0010] A flexible display screen, with its two ends fixed to a first rotating shaft and a second rotating shaft respectively, the first rotating shaft and / or the second rotating shaft being used to wind up the flexible display screen;

[0011] The driving component is mounted on the substrate;

[0012] The transmission component is connected to the driving component, and the driving component is used to drive the transmission component to rotate;

[0013] The transmission wheel is connected to the transmission component, which drives the transmission wheel to rotate.

[0014] A lever, located on the drive wheel, can move the corresponding housing when connected to the first housing and / or the second housing.

[0015] In the embodiments of this application, when the lever is connected to the first housing, the rotation of the lever is converted into linear motion of the first housing; that is, the lever can drive the first housing to move. When the transmission wheel drives the lever to rotate in the first direction, the lever can generate a pushing force on the first housing, causing the first housing to move away from the second housing. When the transmission wheel drives the lever to rotate in the second direction, the lever can generate a pulling force on the first housing, causing the first housing to move closer to the second housing. One of the first and second directions is clockwise, and the other is counterclockwise.

[0016] By moving the first housing using a lever, the electronic device can switch between an extended and retracted state, enabling it to switch between large and small screen modes. Considering the limited installation space in electronic devices, converting rotation into linear motion reduces the space occupied by the drive structure, thus facilitating miniaturization.

[0017] By setting a transmission component between the drive component and the transmission wheel, the transmission ratio between the transmission component and the transmission wheel can be reasonably set, and the rotational speed of the transmission wheel can be controlled within a set range, which helps to improve the stability of electronic equipment when switching states.

[0018] Furthermore, when electronic devices switch between unfolded and retracted states, the flexible display screen does not need to be folded. Therefore, the problem of folding of the flexible display screen is avoided, which prevents damage and breakage caused by frequent folding. This helps to improve the service life of the flexible display screen and enhance the functional stability of electronic devices.

[0036] The following is combined Figures 1-10 This application describes an electronic device according to an embodiment of the present application.

[0037] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to some embodiments of this application, the electronic device includes: a substrate 100, a first housing 200, a second housing 300, a first rotating shaft, a second rotating shaft (not shown in the figure), a flexible display screen 400, a driving member 510, a transmission member 520, a transmission wheel 530, and a lever 540. The first housing 200 and / or the second housing 300 are slidably connected to the substrate 100 so that the electronic device can switch between an unfolded state and a retracted state. The first rotating shaft and the second rotating shaft are respectively disposed within the first housing 200 and the second housing 300, and the first rotating shaft is rotatably connected to the first housing 200 and / or the second rotating shaft is rotatably connected to the second housing 300. The two ends of the flexible display screen 400 are respectively fixed to the first rotating shaft and the second rotating shaft, and the first rotating shaft and / or the second rotating shaft are used to roll up the flexible display screen 400. A driving member 510 is disposed on the base plate 100. A transmission member 520 is connected to the driving member 510. The driving member 510 is used to drive the transmission member 520 to rotate. A transmission wheel 530 is connected to the transmission member 520. The transmission member 520 is used to drive the transmission wheel 530 to rotate. A lever 540 is disposed on the transmission wheel 530. When the lever 540 is connected to the first housing 200 and / or the second housing 300, the lever 540 can drive the corresponding housing to move.

[0038] The first housing 200 and the second housing 300 are mounted on the substrate 100, and the first housing 200 and / or the second housing 300 are slidable relative to the substrate 100.

[0039] In one possible application, the first housing 200 is slidably connected to the substrate 100, and the second housing 300 is fixed to the substrate 100. After the first housing 200 slides on the substrate 100, the distance between the first housing 200 and the second housing 300 changes, and the first housing 200 and the second housing 300 can approach each other or move away from each other.

[0040] In one possible application, the first housing 200 is slidably connected to the substrate 100, and the second housing 300 is also slidably connected to the substrate 100. The first housing 200 and the second housing 300 can be close to or far from each other.

[0041] A first rotating shaft is installed inside a first housing 200, and a second rotating shaft is installed inside a second housing 300. The first rotating shaft is rotatably connected to the first housing 200 and / or the second rotating shaft is rotatably connected to the second housing 300.

[0042] In one possible application, a first rotating shaft is rotatably connected to a first housing 200, and a second rotating shaft is fixedly connected to a second housing 300. The two ends of the flexible display screen 400 are respectively fixed to the first and second rotating shafts. When the first housing 200 and the second housing 300 move away from each other, the flexible display screen 400 wound around the first rotating shaft gradually separates from it. When the first housing 200 and the second housing 300 move closer to each other, the flexible display screen 400 gradually winds back onto the first rotating shaft.

[0043] In one possible application, a first rotating shaft is rotatably connected to a first housing 200, and a second rotating shaft is rotatably connected to a second housing 300. The two ends of the flexible display screen 400 are respectively fixed to the first and second rotating shafts. When the first housing 200 and the second housing 300 are moving away from each other, the portion of the flexible display screen 400 wound on the first rotating shaft gradually separates from the first rotating shaft, and the portion of the flexible display screen 400 wound on the second rotating shaft gradually separates from the second rotating shaft. When the first housing 200 and the second housing 300 are approaching each other, the flexible display screen 400 gradually winds around the first and second rotating shafts.

[0044] The electronic device also includes a drive unit that drives the first and / or second rotating shafts to rotate. The drive unit can be a motor with a gear set.

[0045] In the retracted state, the distance between the first housing 200 and the second housing 300 is L1, and in the extended state, the distance between the first housing 200 and the second housing 300 is L2, where L2 > L1. When the electronic device is extended, the flexible display screen 400 has a larger display area, and when the electronic device is retracted, the flexible display screen 400 has a smaller display area, thus meeting users' needs for both large and small screens in different usage scenarios.

[0046] The driving component 510 is mounted on the base plate 100 and is connected to the transmission component 520. Therefore, the driving component 510 can drive the transmission component 520 to move. The transmission component 520 is connected to the transmission wheel 530, so that the transmission component 520 can drive the transmission wheel 530 to rotate. The lever 540 is disposed on the transmission wheel 530 and can rotate together with the transmission wheel 530.

[0047] When the lever 540 is connected to the first housing 200, the rotation of the lever 540 is converted into linear motion of the first housing 200, that is, the lever 540 can drive the first housing 200 to move. When the transmission wheel 530 drives the lever 540 to rotate in the first direction, the lever 540 can generate a pushing force on the first housing 200, causing the first housing 200 to move away from the second housing 300. When the transmission wheel 530 drives the lever 540 to rotate in the second direction, the lever 540 can generate a pulling force on the first housing 200, causing the first housing 200 to move towards the second housing 300. One of the first direction and the second direction is clockwise, and the other is counterclockwise.

[0048] The lever 540 moves the first housing 200, allowing the electronic device to switch between an extended and retracted state, thus enabling the device to switch between a large and small screen. Considering the limited installation space in the electronic device, converting rotation into linear motion reduces the space occupied by the drive structure, which is beneficial for miniaturizing the electronic device.

[0049] By setting a transmission component 520 between the drive component 510 and the transmission wheel 530, the transmission ratio between the transmission component 520 and the transmission wheel 530 can be reasonably set, and the rotational speed of the transmission wheel 530 can be controlled within a set range, which is beneficial to improving the stability of the electronic equipment when switching states.

[0050] Furthermore, when the electronic device switches between the unfolded and retracted states, the flexible display screen 400 does not need to be folded. Therefore, the flexible display screen 400 will not be folded, which avoids the problem of damage or breakage caused by frequent folding. This helps to improve the service life of the flexible display screen 400 and enhance the functional stability of the electronic device.

[0051] Combination Figure 3 , Figure 4 and Figure 6 As shown, in one possible embodiment, the lever 540 extends along the axial direction of the transmission wheel 530, and a groove is provided on the housing connected to the lever 540. At least a portion of the lever 540 extends into the groove and can slide within the groove so that the lever 540 can drive the housing to move.

[0052] The slide groove 210 is provided as an example in the first housing 200. Since the lever 540 extends along the axial direction of the drive wheel 530, the opening of the slide groove 210 is located at the top or bottom of the slide groove 210 so that the lever 540 can slide in the slide groove 210. Therefore, the lever 540 can extend into the slide groove 210 when rotating.

[0053] When the lever 540 slides within the groove 210, the lever 540 can pull or push the inner wall of the groove 210, thereby driving the first housing 200 to move.

[0054] In one possible application, the groove 210 extends along the length of the transmission member 520. Alternatively, the groove 210 may be an arc-shaped groove that bends away from the second housing 300, and the radius of the arc-shaped groove needs to be larger than the radius of the transmission wheel 530.

[0055] The principle of the slide groove 210 being set in the second housing 300 is the same as described above, and will not be repeated here.

[0056] In one possible embodiment, transmission wheels 530 are provided on both sides of the transmission member 520. The transmission wheels 530 on both sides of the transmission member 520 rotate in opposite directions. The transmission wheels 530 on both sides of the transmission member 520 drive the first housing 200 and the second housing 300 to slide respectively through the lever 540.

[0057] By using a single transmission component 520 to simultaneously move two sets of transmission wheels 530, it is possible to ensure that the first housing 200 and the second housing 300 move at the same speed and with the same amount of movement within the same time period, thereby improving the stability of the flexible display screen 400 when switching between different states. Moreover, by using only one transmission component 520 to move two sets of transmission wheels 530 simultaneously, the number of drive components 510 can be reduced, simplifying the structure of the electronic device.

[0058] In one possible application, the number of transmission wheels 530 located on both sides of the transmission member 520 is at least two, so that the first housing 200 and the second housing 300 have at least two force points, which is beneficial to improving the smoothness of movement of the first housing 200 and the second housing 300.

[0059] In one possible embodiment, the transmission element 520 includes a worm gear, and the transmission wheel 530 includes a turbine.

[0060] The worm gear can drive the turbine to rotate, and the lever 540 is set on the turbine.

[0061] In one possible application, the drive element 510 is a motor.

[0062] In other embodiments, the transmission member 520 includes a drive gear and a rack, the drive gear meshing with the rack, the drive member 510 can drive the drive gear to rotate, the drive gear drives the rack to move, the transmission wheel 530 is a driven gear, and the rack can drive the driven gear to rotate.

[0063] like Figure 4 As shown, in one possible embodiment, at least one of the first housing 200 and the second housing 300 is slidably connected to the substrate 100. The electronic device further includes: an elastic component 600 connected to the substrate 100, and a housing slidably connected to the substrate 100 is connected to the elastic component 600. In a contracted state, the elastic component 600 is in an elastically deformed state, and in an unfolded state, the elastic component 600 is in its original state.

[0064] In the first housing 200 and the second housing 300, the housing that is slidably connected to the substrate 100 is connected to the elastic component 600. It is possible that one of the first housing 200 and the second housing 300 is connected to the elastic component 600, or the first housing 200 and the second housing 300 are respectively connected to different elastic components 600. Since the mating structure of the first housing 200 connected to the elastic component 600 and the mating structure of the second housing 300 connected to the elastic component 600 are the same, the following embodiments will be exemplarily described with the first housing 200 slidably connected to the substrate 100 and the second housing 300 slidably connected to the substrate 100.

[0065] The elastic component 600 is connected to the substrate 100 and the first housing 200. When the electronic device is in a retracted state, the elastic component 600 is in an elastic deformation state, at which time the elastic component 600 accumulates elastic potential energy. When the electronic device is in an extended state, the elastic component 600 is in its original state. Therefore, when the electronic device switches from a retracted state to an extended state, the elastic component 600 can push the first housing 200. During this process, the elastic component 600 can push the first housing 200 together with the lever 540.

[0066] By adding the elastic component 600 to push the first housing 200, it is beneficial to improve the smoothness of the movement of the electronic device from the retracted state to the unfolded state.

[0067] In one possible application, there are two elastic components 600. The two first elastic components 600 are arranged at intervals. The two elastic components 600 can be located on both sides of the length direction of the electronic device. By arranging the two elastic components 600, the two sides of the first housing 200 can be balanced by force, and the first housing 200 can be prevented from shifting.

[0068] like Figure 5As shown, in one possible embodiment, the elastic component 600 includes a fixing block 610, an elastic element (not shown), and a push rod 630. The fixing block 610 is disposed on the substrate 100 and has a mounting cavity, in which the elastic element is located. The first end of the push rod 630 is connected to a housing that is slidably connected to the substrate 100, and the second end of the push rod 630 extends into the mounting cavity and contacts the elastic element.

[0069] The elastic element is installed in the mounting cavity. Its two ends are connected to a fixing block 610 and a push rod 630, respectively. The fixing block 610 is mounted on the substrate 100, so its position relative to the substrate 100 remains unchanged, allowing the elastic element to push the push rod 630. Since a portion of the push rod 630 extends into the mounting cavity, the cavity guides the push rod 630, preventing it from deflecting and ensuring that the push rod 630 can stably push the first housing 200.

[0070] In one possible application, the elastic element can be a compression spring.

[0071] Combination Figure 5 , Figure 6 and Figure 7 As shown, in one possible embodiment, the electronic device further includes a guide groove 110 and a slider 230. The guide groove 110 is disposed on the side wall of the substrate 100, and the slider 230 is disposed in a housing that is slidably connected to the substrate 100, and the slider 230 can slide within the guide groove 110.

[0072] When the first housing 200 is slidably connected to the substrate 100, the slider 230 is located in the guide groove 110. The guide groove 110 guides the slider 230, ensuring that the slider 230 can move in a straight line stably. The slider 230 is set on the first housing 200, thereby ensuring that the first housing 200 can move in a straight line stably, avoiding the first housing 200 from deviating, and improving the stability of the movement of the first housing 200.

[0073] The principle of the second housing 300 slidingly connected to the substrate 100 is the same as described above, and will not be repeated here.

[0074] Combination Figure 5 , Figure 6 and Figure 7 As shown, in one possible embodiment, the electronic device further includes a limiting post 120, which is disposed on the substrate 100 and located in the guide groove 110. In the unfolded state, the slider 230 contacts the limiting post 120.

[0075] When the first housing 200 is slidably connected to the substrate 100, it is necessary to limit the extreme positions of the movement of the first housing 200. Similarly, when the second housing 300 is slidably connected to the substrate 100, it is necessary to limit the extreme positions of the movement of the second housing 300.

[0076] Specifically, when the first housing 200 is slidably connected to the substrate 100, a limiting post 120 is provided in the guide groove 110. When the electronic device is in the unfolded state, the slider 230 contacts the limiting post 120. At this time, the limiting post 120 restricts the slider 230 from continuing to move away from the second housing 300, thereby limiting the first housing 200 to the extreme position.

[0077] By limiting the extreme position of the first housing 200 by the limiting post 120, it is possible to avoid the problem of excessive movement of the first housing 200 causing stretching of the flexible display screen 400, and also to ensure that the first housing 200 can move stably from the unfolded state to the retracted state.

[0078] The second housing 300 is slidably connected to the substrate 100 at a distance from the same location as described above, and will not be repeated here.

[0079] Combination Figure 9 and Figure 10 As shown, in one possible embodiment, the electronic device includes a support plate 800 and an elastic reset assembly 900. The support plate 800 is slidably connected to the first housing 200 and the second housing 300. A drive wheel 530 can push the support plate 800 to move away from the substrate 100. In the unfolded state, the support plate 800 supports the flexible display screen 400. The support plate 800 and the substrate 100 are connected to the elastic reset assembly 900. When the drive wheel 530 rotates to a first position, the elastic reset assembly 900 is in a first elastic deformation state, and the support plate 800 supports the flexible display screen 400. When the drive wheel 530 rotates to a second position, the elastic reset assembly 900 is in either the original state or the second elastic deformation state. The support plate 800 and the flexible display screen 400 are spaced apart. The deformation of the elastic reset assembly 900 in the first elastic deformation state is greater than the deformation in the second elastic deformation state.

[0080] During the rotation of the drive wheel 530, the drive wheel 530 can push the support plate 800. Specifically, when the electronic device is in the unfolded state, the support plate 800 supports the flexible display screen 400.

[0081] When the electronic device is in the unfolded state, the first housing 200 and the second housing 300 are far apart, which causes part of the flexible display screen 400 to be suspended in the air. Therefore, the flexible display screen 400 is supported by the support plate 800 to prevent the flexible display screen 400 from collapsing due to user pressure, thus protecting the flexible display screen 400 and ensuring the user experience when pressing the flexible display screen 400.

[0082] An elastic reset component 900 is provided between the support plate 800 and the substrate 100. During the process of the drive wheel 530 pushing the support plate 800, the elastic component undergoes elastic deformation. When the support plate 800 moves to a position supporting the flexible display screen 400, the elastic component is in a first elastic deformation state. When the electronic device switches from an unfolded state to a retracted state, the drive wheel 530 moves away from the support plate 800, and the elastic reset component 900 pulls the support plate 800 with elastic force, automatically realizing the reset function of the support plate 800.

[0083] When the electronic device is in the deployed state, the drive wheel 530 is in the first position; when the electronic device is in the retracted state, the drive wheel 530 is in the second position.

[0084] When the transmission wheel 530 is in the second position, the elastic reset component 900 can be in its original state, that is, in a state without elastic deformation. Of course, when the transmission wheel 530 is in the second position, the elastic reset component 900 can also be in a second elastic deformation state. The deformation in the second elastic deformation state is less than the deformation in the first elastic deformation state, ensuring that the elastic reset component 900 can stably pull the support plate 800 back to its original position.

[0085] In one possible application, the elastic reset component 900 can be a tension spring.

[0086] Combination Figure 8 and Figure 9 As shown, in one possible embodiment, a first inclined slider 531 is provided on the transmission wheel 530, and the first inclined slider 531 is arranged circumferentially along the transmission wheel 530. A second inclined slider 810 is provided on the support plate 800, and the first inclined slider 531 can push the second inclined slider 810 along the axial direction of the transmission wheel 530.

[0087] The first inclined slider 531 and the second inclined slider 810 have a gradually changing thickness. During the rotation of the transmission wheel 530, the first inclined slider 531 on the transmission wheel 530 rotates. As the first inclined slider 531 rotates, it slides relative to the second inclined slider 810, allowing the first inclined slider 531 to push the second inclined slider 810, thereby pushing the support plate 800. By cooperating with the first inclined slider 531 and the second inclined slider 810, the transmission wheel 530 can directly push the support plate 800, eliminating the need for a separate drive structure for the support plate 800 and further simplifying the structure of the electronic device.

[0088] In one possible embodiment, one end of the slide groove 210 is provided with a slide outlet (not shown in the figure), and the lever 540 can extend out of the slide groove 210 from the first slide outlet. When the slider 230 is in contact with the limiting post 120, the lever 540 extends out of the slide groove 210, and the first inclined slider 531 is in contact with the second inclined slider 810. When the slider 230 is located in the slide groove 210, the first inclined slider 531 and the second inclined slider 810 separate.

[0089] During the process of pushing the first housing 200, when the lever 540 pushes the first housing 200 to its limit position, the limiting post 120 limits the slider 230, preventing the first housing 200 from moving further, while the transmission wheel 530 can continue to rotate, thereby pushing the support plate 800. To avoid interference between the slide groove 210 and the lever 540, a sliding outlet is provided on the side wall of the slide groove 210, through which the lever 540 can extend out of the slide groove 210. When the electronic device switches from a retracted state to an extended state, the lever 540 can extend into the slide groove 210 from the sliding outlet, allowing the lever 540 to engage with the inner wall of the slide groove 210, thereby pulling the first housing 200.

[0090] like Figure 5 As shown, in one possible embodiment, the first housing 200 and / or the second housing 300 are provided with receiving cavities. When the lever 540 extends out of the slide groove, the support plate 800 extends out of the receiving cavity. When the lever 540 is located in the slide groove, a portion of the support plate 800 is located in the receiving cavity.

[0091] When the electronic device is in a retracted state, the receiving cavity 240 accommodates the support plate 800, preventing the movement of the first housing 200 and / or the second housing 300 from interfering with the support plate 800.

[0092] In one possible application, the electronic device could be a mobile phone, television, tablet computer, e-book reader, or projector.
