Description

Technical Field

[0001] This application relates to the field of display technologies, and particularly to a sliding screen support mechanism and a display device. Background Art

[0002] Compared with traditional display screens, flexible screens have the characteristics of being thin, light, low-power, bendable, and having good flexibility. Therefore, flexible screens are increasingly used in terminal devices. With the development of flexible screens, sliding screens that achieve screen expansion and contraction through sliding have emerged, enabling smaller personal terminals to obtain a larger screen display ratio. However, current sliding screens have the problem of poor touch feel. Summary of the Invention

[0003] Based on this, it is necessary to provide a sliding screen support mechanism and a display device for the problem of poor touch feel of sliding screens.

[0004] According to one aspect of the present application, a sliding screen support mechanism is provided, including: a first support plate having a first side; and a second support plate slidably connected to the second side of the first support plate along a first direction; the first side and the second side are oppositely arranged; wherein, along the first direction, the second support plate is configured to be movable relative to the first support plate between a first critical position and a second critical position; the second support plate has a first surface and a second surface that are located on the same side of the second support plate and are in different planes; at the first critical position, the first surface is flush with the surface of the first side of the first support plate, and the second surface is located below the surface of the second side of the first support plate; at the second critical position, both the first surface and the second surface are located below the surface of the second side of the first support plate.

[0005] The sliding screen support mechanism provided by the embodiments of the present application configures the second support plate to be movable relative to the first support plate between the first critical position and the second critical position, and the same side of the second support plate has a first surface and a second surface in different planes, so that after the second support plate moves relative to the first support plate, the first surface can be flush with the surface of the first side of the first support plate or hidden below the surface of the second side of the first support plate. In this way, when the second support plate moves to the first critical position, the first surface of the second support plate and the surface of the first side of the first support plate can simultaneously support the flexible display screen to achieve a larger-size screen display. When the second support plate moves to the second critical position, the first surface of the second support plate can move below the surface of the second side of the first support plate, and the surface of the first side of the first support plate is used to separately support the flexible display screen to achieve a smaller-size flat display. Since the flexible display screen can be well supported in both sizes, the touch feel of the screen is improved.

[0006] In some embodiments, the second support plate includes a support section, a transition section, and a connection section that are sequentially connected along the first direction; the first surface is disposed on the support section, and the second surface is disposed on the connection section. The support section and the connection section are connected by the transition section, so that the first surface and the second surface are separated, and the first surface and the second surface are located on different planes respectively.

[0007] Optionally, the support section and the connection section are arranged in parallel, and the transition section is configured to be inclined relative to the support section and the connection section, so that the first surface and the second surface are in different planes. Since the transition section is inclined relative to the support section and the connection section, when the second support plate moves relative to the first support plate, the movement of the transition section includes a component movement parallel to the support section and a component movement perpendicular to the support section. In this way, it can drive the support section to move up and down in a direction perpendicular to the extending direction of its own length, so as to change the height of the first surface, and realize that the first surface is flush with the first side surface of the first support plate or hidden below the first side surface of the first support plate.

[0008] Optionally, the transition section is provided with a transition surface that smoothly transitions with the first surface and the second surface. In this way, during the process of the second support plate moving relative to the first support plate, when the transition section passes through the end of the first support plate, the transition section can move smoothly.

[0009] Optionally, the cross-sectional contour line of the transition surface is a curve.

[0010] Optionally, the cross-sectional contour line of the transition surface is in an arc shape.

[0011] In some embodiments, at the first critical position, the support section extends out of the first support plate along the first direction, and at least a part of the transition section extends out of the first support plate; at the second critical position, the support section and the transition section are completely located below the surface on the second side of the first support plate. In this way, when the second support plate moves to the first critical position, the support section completely extends out of the first support plate, so that the transition section can be fully utilized to support the flexible display screen; when the second support plate moves to the second critical position, the support section is completely hidden below the first support plate, so that on the premise that the display area corresponding to the second critical position is determined, the size of the display device is reduced as much as possible.

[0012] In some embodiments, the thickness of the support section is 0.1 mm to 0.2 mm; the height difference between the connection section and the support section in the thickness direction is 0.2 mm to 0.3 mm. In this way, the overall thickness of the sliding screen support mechanism is relatively small.

[0013] In some embodiments, the sliding screen support mechanism is used to support a flexible display screen; the flexible display screen includes a first display portion and a second display portion connected to each other. At the first critical position, the first display portion and the second display portion are supported on the surface of the first side of the first support plate and the first surface of the second support plate; at the second critical position, the first display portion is supported on the surface of the first side of the first support plate, and at least a part of the second display portion is located below the surface of the second side of the first support plate. Based on this, when the position of the second display portion changes, the support area is changed by the relative movement of the second support plate with respect to the first support plate, so as to ensure good support in different display states.

[0014] In some embodiments, the flexible display screen further includes a winding portion connected to the second display portion; the sliding screen support mechanism further includes a rotating shaft disposed beside the first support plate along the first direction; the winding portion is wound around the rotating shaft to guide at least a part of the second display portion to be located on the second side of the first support plate during the movement of the second support plate. By guiding the second display portion to the second side of the first support plate for storage through the rotating shaft, the stored part can be kept flat under the support of the rotating shaft, thereby avoiding wrinkles in the flexible display screen during the storage process.

[0015] In some embodiments, the sliding screen support mechanism further includes a roller that can rotate around its own axis; the roller is located on the side of the second support plate facing away from the first support plate, and a first tooth pattern is provided on the outer surface of the roller; a second tooth pattern that can mesh with the first tooth pattern is provided on the side of the second support plate facing away from the first support plate, so as to drive the second support plate to move along the first direction during the rotation of the roller. Based on this, when the roller rotates around its own axis, it will drive the second support plate to move along the first direction, realizing the conversion between small-size display and large-size display.

[0016] In some embodiments, the sliding screen support mechanism further includes a driving member, and the driving end of the driving member is connected to the roller to drive the roller to rotate around its own axis. The relative movement between the second support plate and the first support plate is realized by driving the roller to rotate through the driving member.

[0017] Optionally, the driving end of the driving member is further connected to the flexible display screen, so that when the second support plate moves relative to the first support plate, at least a part of the second display portion rotates around the rotating shaft to the second side of the first support plate. In this way, the driving member can not only drive the movement of the second support plate, but also drive the movement of the flexible display screen, saving the space for additionally arranging a driving device.

[0018] In some embodiments, a guiding groove extending along the first direction is provided on the second side of the first support plate; the second support plate is slidably connected to the guiding groove. Through the arrangement of the guiding groove, the movement of the second support plate is guided, making the movement process of the second support plate relative to the first support plate smoother and more stable.

[0019] Optionally, two guiding members are oppositely arranged along the second direction on the second side of the first support plate, and the guiding groove is arranged on the two opposite sides of the two guiding members; the first direction is perpendicular to the second direction. By arranging two opposite guiding members along the second direction and arranging the guiding groove on the guiding members, the structure of the first support plate can be prevented from being damaged, thereby ensuring the structural strength of the first support plate.

[0020] Optionally, each guiding member includes a plurality of guiding blocks arranged at intervals along the first direction, and the plurality of guiding blocks of the two guiding members are arranged in one-to-one correspondence; sub-guiding grooves are respectively provided on one side of the two one-to-one corresponding guiding blocks facing each other. In this way, the total weight of the guiding members can be reduced.

[0021] According to another aspect of the present application, a display device is further provided, including: a flexible display screen, the flexible display screen includes adjacent first and second display portions; the sliding screen support mechanism as described above; at the first critical position, the first and second display portions are supported on the surface of the first side of the first support plate and the first surface of the second support plate; at the second critical position, the first display portion is supported on the surface of the first side of the first support plate, and at least part of the second display portion is located below the surface of the second side of the first support plate. Based on this, the sliding screen support mechanism can play a good supporting role in different display states of the flexible display screen, thereby improving the touch feel of the display device.

[0034] In order to make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0035] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0036] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0037] In this application, unless otherwise clearly defined and limited, terms such as "installed", "connected", "joined", "fixed", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] In this application, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or just means that the first feature is at a higher horizontal level than the second feature.

[0039] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be a middle element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a middle element at the same time. The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0040] A sliding screen generally includes a flexible screen body and a support mechanism. When the sliding screen is in a contracted state, part of the flexible screen body is hidden. When the sliding screen is in an extended state, the hidden part of the flexible screen body expands, and the expanded part needs to be supported by the support mechanism. For example, in the related art, the support mechanism of the sliding screen is a transmission belt, and the expanded flexible screen body of the sliding screen is supported by the transmission belt. However, since the transmission belt used is usually in the shape of a comb or a tank chain, there are hollow areas on the support surface of the support mechanism in the extended state, that is, the support surface of the support mechanism for the flexible screen body is uneven, resulting in a concave-convex feeling when touching the sliding screen after it is unfolded, and even bulging may occur, affecting the user experience.

[0041] To solve the above problems, the present application provides a sliding screen support mechanism. By the relative movement of two relatively movable support plates, the support area for the flexible display panel is changed, so that the exposed flexible display panel can be well supported under different support areas, and the flexible display panel remains flat after being unfolded, thereby improving the user experience.

[0042] The sliding screen support mechanism provided by the embodiments of the present application can be used in mobile phones, tablet computers, laptop computers, in-vehicle display devices, etc.

[0043] Figure 1 The structural schematic diagram of the sliding screen support mechanism in an embodiment of the present application is shown. Figure 2 The structural schematic diagram of the first support plate of the sliding screen support mechanism in an embodiment of the present application is shown. Figure 3 The structural schematic diagram of the second support plate of the sliding screen support mechanism in an embodiment of the present application is shown.

[0044] Referring to Figures 1 to 3 , the sliding screen support mechanism provided by an embodiment of the present application includes a first support plate 21 and a second support plate 22. The first support plate 21 has a first side 21a and a second side 21b that are oppositely arranged. The second support plate 22 is slidably connected to the second side 21b of the first support plate 21 along the first direction X; along the first direction X, the second support plate 22 is configured to be able to move relative to the first support plate 21 between a first critical position and a second critical position; the second support plate 22 has a first surface 22a and a second surface 22b that are located on the same side of the second support plate 22 and are in different planes; at the first critical position, the first surface 22a is flush with the surface of the first side 21a of the first support plate 21, and the second surface 22b is located below the surface of the second side of the first support plate 21; at the second critical position, both the first surface 22a and the second surface 22b are located below the surface of the second side 21b of the first support plate 21. When the sliding screen support mechanism is applied to a display device, the first support plate 21 can be fixed to the housing of the display device.

[0045] The sliding screen support mechanism provided by the embodiment of the present application configures the second support plate 22 to be movable relative to the first support plate 21 between a first critical position and a second critical position, and the same side of the second support plate 22 has a first surface 22a and a second surface 22b in different planes. After the second support plate 22 moves relative to the first support plate 21, the first surface 22a can be flush with the surface of the first side 21a of the first support plate 21 or hidden below the surface of the second side 21b of the first support plate 21. Thus, when the second support plate 22 moves to the first critical position, the first surface 22a of the second support plate 22 and the surface of the first side 21a of the first support plate 21 can simultaneously support the flexible display screen 10 to achieve a larger-size screen display. When the second support plate 22 moves to the second critical position, the first surface 22a of the second support plate 22 can move below the surface of the second side 21b of the first support plate 21, and the surface of the first side 21a of the first support plate 21 is used to separately support the flexible display screen 10 to achieve a smaller-size flat display. Since the flexible display screen 10 can be well supported in both size states, the touch feel of the screen is improved.

[0046] Exemplarily, considering that the shape of a commonly used display device is rectangular, the first support plate 21 is set as a rectangular plate, and the second support plate 22 includes two rectangular plates with different heights and a connecting plate connected between the two rectangular plates with different heights; preferably, the two rectangular plates with different heights and the connecting plate of the second support plate 22 are integrally formed to ensure that the second support plate 22 has strong structural strength. In other embodiments, according to the shape of the display device, the shapes of the first support plate 21 and the second support plate 22 can be adjusted.

[0047] In some embodiments, the second support plate 22 includes a support section 221, a transition section 222, and a connection section 223 connected in sequence along the first direction X. The first surface 22a is disposed on the support section 221, and the second surface 22b is disposed on the connection section 223. Thus, the support section 221 and the connection section 223 are connected by the transition section 222 to separate the first surface 22a and the second surface 22b, so that the first surface 22a and the second surface 22b are located in different planes respectively.

[0048] Optionally, the support segment 221 and the connection segment 223 are arranged in parallel, and the transition segment 222 is configured to be inclined with respect to the support segment 221 and the connection segment 223, so that the first surface 22a and the second surface 22b are in different planes. Since the transition segment 222 is inclined with respect to the support segment 221 and the connection segment 223, when the second support plate 22 moves relative to the first support plate 21, the movement of the transition segment 222 includes a component movement parallel to the support segment 221 and a component movement perpendicular to the support segment 221. In this way, it can drive the support segment 221 to move up and down in a direction perpendicular to the extension direction of its own length, so as to change the height of the first surface 22a, realizing that the first surface 22a is flush with the surface of the first side 21a of the first support plate 21 or hidden below the surface of the first side 21a of the first support plate 21. Further, both the support segment 221 and the connection segment 223 are parallel to the first direction X, so that the movement of the second support plate 22 in the first direction X is smooth.

[0049] Optionally, the transition segment 222 is provided with a transition surface that smoothly transitions with the first surface 22a and the second surface 22b. In this way, during the process of the second support plate 22 moving relative to the first support plate 21, when the transition segment 222 passes through the end of the first support plate 21, the transition segment 222 can move smoothly. Among them, the cross-sectional contour line of the transition surface can be set as a curve, so that the transition segment 222 forms a smooth transition surface. The curve can be further set as an arc, so that the transition segment 222 needs to bypass fewer curves during the process of passing through the end of the first support plate 21.

[0050] In some embodiments, when the second support plate 22 moves to the first critical position, the support segment 221 extends out of the first support plate 21 in the first direction X, and at least a part of the transition segment 222 extends out of the first support plate 21. In this way, when the second support plate 22 moves to the first critical position, the support segment 221 completely extends out of the first support plate 21, so that the transition segment 222 can be fully utilized to support the flexible display screen 10. When the second support plate 22 moves to the second critical position, the support segment 221 and the transition segment 222 are completely located below the surface of the second side of the first support plate 21. In this way, when the second support plate 22 moves to the second critical position, the support segment 221 is completely hidden under the first support plate 21, so as to minimize the size of the display device on the premise that the display area corresponding to the second critical position is determined.

[0051] In some embodiments, the thickness of the support section 221 is 0.1 mm to 0.2 mm. Optionally, the thickness of the support section 221 is 0.1 mm, 0.12 mm, 0.14 mm, 0.16 mm, 0.18 mm, or 0.2 mm. The height difference in the thickness direction between the connecting section 223 and the support section 221 is 0.2 mm to 0.3 mm. Optionally, the height difference in the thickness direction between the connecting section 223 and the support section 221 is 0.2 mm, 0.22 mm, 0.24 mm, 0.26 mm, 0.28 mm, or 0.3 mm. Considering that the smaller the thickness of the support section 221 and the height difference in the thickness direction between the connecting section 223 and the support section 221, the smaller the total thickness of the sliding screen support mechanism. At the same time, considering that the support section 221 needs to have a certain structural strength to ensure a good support effect, in this embodiment, the thickness of the support section 221 is set to 0.1 mm to 0.2 mm, and the height difference in the thickness direction between the connecting section 223 and the support section 221 is set to 0.2 mm to 0.3 mm, so as to ensure the structural strength of the sliding screen support mechanism while ensuring a relatively small overall thickness of the sliding screen support mechanism.

[0052] Figure 4 FIG. 4 shows a schematic structural view of a first state in which the sliding screen support mechanism supports the flexible display screen according to an embodiment of the present application. Figure 5 FIG. 5 shows a schematic structural view of a second state in which the sliding screen support mechanism supports the flexible display screen according to an embodiment of the present application.

[0053] Referring to Figure 4 and Figure 5 , optionally, the sliding screen support mechanism is used to support the flexible display screen 10. The flexible display screen 10 includes a first display portion A1 and a second display portion A2. When the second support plate 22 moves to the first critical position, the first display portion A1 and the second display portion A2 are supported on the first side 21a of the first support plate 21 and the first surface 22a of the second support plate 22. When the second support plate 22 moves to the second critical position, the first display portion A1 is supported on the surface of the first side 21a of the first support plate 21, and at least a part of the second display portion A2 is located below the surface of the second side 21b of the first support plate 21. Based on this, when the position of the second display portion A2 changes, by moving the second support plate 22 relative to the first support plate 21, the support area is changed, so as to ensure good support in different display states.

[0054] Optionally, the flexible display screen 10 further includes a winding portion A3 connected to the second display portion A2; the sliding screen support mechanism further includes a rotating shaft 24 disposed beside the first support plate 21 along the first direction X; the winding portion A3 is wound around the rotating shaft 24 to guide at least a part of the second display portion A2 to be located on the second side 21b of the first support plate 21 during the movement of the second support plate 22. The second display portion A2 is guided to the second side 21b of the first support plate 21 for storage through the rotating shaft 24, so that the stored part can be kept flat under the support of the rotating shaft 24, thereby avoiding wrinkles in the flexible display screen 10 during the storage process.

[0055] In some embodiments, the sliding screen support mechanism further includes a roller 23 capable of rotating about its own axis. The roller 23 is located on the side of the second support plate 22 away from the first support plate 21, and the outer surface of the roller 23 is provided with first tooth lines. The side of the second support plate 22 away from the first support plate 21 is provided with second tooth lines capable of meshing with the first tooth lines to drive the second support plate 22 to move along the first direction X during the rotation of the roller 23. Based on this, when the roller 23 rotates about its own axis, it will drive the second support plate 22 to move along the first direction X to realize the conversion between small-size display and large-size display.

[0056] Exemplarily, the material of the second support member is aluminum alloy or stainless steel. Based on this, the second support member has a certain elasticity, so that during the movement of the second support plate 22 between the first critical position and the second critical position, the roller 23 can closely adhere to the second support plate 22, playing a good supporting and guiding role for the second support plate 22, and at the same time avoiding the second support plate 22 from getting stuck during movement.

[0057] In some embodiments, the sliding screen support mechanism further includes a driving member (not shown in the figure). The driving end of the driving member is connected to the roller 23 to drive the roller 23 to rotate about its own axis. Exemplarily, the driving member is a motor, and the power output by the motor is transmitted to the roller through gears and racks to drive the roller to rotate. The relative movement between the second support plate 22 and the first support plate 21 is realized by driving the roller 23 to rotate through the driving member.

[0058] Optionally, the driving end of the driving member is also connected to the flexible display screen 10, so that when the second support plate 22 moves relative to the first support plate 21, at least a part of the second display portion A2 rotates around the rotating shaft 24 to the second side 21b of the first support plate 21. In this way, the driving member can not only drive the movement of the second support plate 22, but also drive the movement of the flexible display screen 10, saving the space for additionally arranging a driving device. Exemplarily, a connecting piece is provided at the end of the flexible display screen 10, and is connected to the driving end of the driving member through the connecting piece, so that the driving force generated by the driving member is evenly dispersed, avoiding excessive local stress on the flexible display screen 10. Wherein, the connecting piece and the driving member can be further connected through a transmission mechanism, and the specific structure of the transmission mechanism can refer to the transmission mechanism in the related art, which will not be elaborated here.

[0059] In other embodiments, the movement of the flexible display screen 10 and the rotation of the roller 23 can be driven by separate independent driving devices respectively. Exemplarily, in the case of a relatively large space such as in-vehicle display, the movement of the flexible display screen 10 and the rotation of the roller 23 are independently driven by their respective corresponding driving devices, while in the case of a relatively small space such as a mobile phone, the movement of the flexible display screen 10 and the rotation of the roller 23 share the same driving device.

[0060] Refer to Figure 1 and Figure 2 , in some embodiments, a guiding groove 212 extending along the first direction X is provided on the second side 21b of the first support plate 21, and the second support plate 22 is slidably connected to the guiding groove 212. Through the arrangement of the guiding groove 212, the movement of the second support plate 22 is guided, making the movement process of the second support plate 22 relative to the first support plate 21 smoother and more stable.

[0061] Optionally, two guiding members 211 are oppositely arranged along the second direction Y on the second side 21b of the first support plate 21, and the guiding groove 212 is arranged on the opposite sides of the two guiding members 211 facing each other, and the first direction X and the second direction Y are perpendicular to each other. By arranging two opposite guiding members 211 along the second direction Y and arranging the guiding groove 212 on the guiding members 211, the structure of the first support plate 21 can be prevented from being damaged, thus ensuring the structural strength of the first support plate 21.

[0062] Wherein, the guiding member 211 can be a long strip-shaped structure extending along the first direction X, or a plurality of block-shaped structures arranged at intervals along the first direction X. Exemplarily, each guiding member 211 includes a plurality of guiding blocks arranged at intervals along the first direction X, and the plurality of guiding blocks of the two guiding members 211 are arranged in one-to-one correspondence, and sub-guiding grooves 212 are respectively provided on the opposite sides of the two one-to-one corresponding guiding blocks facing each other. The plurality of sub-guiding grooves 212 can cooperate to form a long guiding groove 212, realizing the guiding of the movement process of the second support plate 22, and at the same time being able to reduce the total weight of the guiding member 211.
