Abstract

This application provides a flexible screen support device and a display device. During operation, the flexible screen support device has a first state and a second state. When the flexible screen support device enters the second state, the support mechanism can support the flexible screen under the drive of the transmission mechanism. When the flexible screen support device transitions from the second state to the first state, the support mechanism can detach from the flexible screen under the drive of the transmission mechanism. When supporting the flexible screen, the support mechanism can support the stress points of the flexible screen.

Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a flexible screen support device and a display device. Background Technology

[0002] Flexible display devices, with their unique form factors such as folding, large-angle bending, and rolling, are finding increasing applications. For example, foldable display devices offer a larger display area when unfolded and a smaller, more portable size when folded, thus attracting widespread attention.

[0003] In related technologies, a display device may include a mounting base and a flexible screen. The flexible screen is mounted on the mounting base, which has mechanical strength and can support the flexible screen.

[0004] However, the aforementioned flexible screens are prone to collapse and deformation, affecting the lifespan of the display device. Summary of the Invention

[0005] In view of the above problems, this application provides a flexible screen support device and a display device, which can reduce the collapse and deformation of the flexible screen, thereby ensuring the normal service life of the display device.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A first aspect of this application provides a flexible screen support device for supporting a flexible screen of a display device. The flexible screen support device has a first state and a second state.

[0008] The flexible screen support device includes a drive mechanism, a transmission mechanism, and a support mechanism. The drive mechanism is connected to the support mechanism through the transmission mechanism. The drive mechanism is configured to drive the support mechanism to move closer to or further away from the flexible screen through the transmission mechanism.

[0009] The support mechanism is configured to support the flexible screen under the drive of the transmission mechanism when the flexible screen support device is in the second state, and is configured to detach from the flexible screen under the drive of the transmission mechanism when the flexible screen support device is in the first state.

[0010] The flexible screen support device provided in this application embodiment has a first state and a second state during operation. When the flexible screen support device enters the second state, the support mechanism can support the flexible screen under the drive of the transmission mechanism. When the flexible screen support device transitions from the second state to the first state, the support mechanism can detach from the flexible screen under the drive of the transmission mechanism. When the support mechanism supports the flexible screen, it can support the stress points of the flexible screen. Therefore, when the stress points of the flexible screen are subjected to gravity and pressing force during click operations, the presence of the support mechanism can greatly reduce the deformation of the stress points of the flexible screen, thereby ensuring the service life of the flexible screen.

[0011] In one possible implementation, a base is also included, and the drive mechanism includes a drive wheel and a driven wheel. The drive wheel and the driven wheel are linked and both are mounted on the base, and the driven wheel is connected to the transmission mechanism.

[0012] In this way, the transmission structure of the drive wheel and driven wheel is simple and reliable, easy to install on the base, and can reduce installation and maintenance costs.

[0013] In one possible implementation, the support mechanism includes a support member with a support plane on the side facing the flexible screen, and the support member moves in a direction perpendicular to the support plane under the drive of the transmission mechanism.

[0014] The transmission mechanism includes a first transmission rod, the first end of which is connected to the axle of the driven wheel, and the second end of which is slidably connected to the support member; the sliding direction of the second end of the first transmission rod is parallel to the extension direction of the support plane.

[0015] Thus, the existence of the first transmission rod simplifies the structure of the transmission mechanism and makes the transmission process simple and reliable.

[0016] In one possible implementation, the transmission mechanism further includes a slide groove disposed on the base. The transmission mechanism includes a first auxiliary rod, the first end of which is slidably disposed in the slide groove, and the second end of which is rotatably connected to the second end of the first transmission rod, and both are slidably connected to the support member.

[0017] In this way, the first auxiliary rod can cooperate with the movement of the first transmission rod and provide auxiliary support for the first transmission rod, sharing the force on the first transmission rod, thereby extending the service life of the first transmission rod.

[0018] In one possible implementation, the transmission mechanism further includes an auxiliary transmission component, the driven wheel is linked to the auxiliary transmission component, and at least part of the auxiliary transmission component is slidably connected to the support member; the auxiliary transmission component is configured to be driven by the driven wheel when the driven wheel rotates, so as to drive the support member to move.

[0019] Preferably, the auxiliary transmission assembly includes a support rod, which is connected to the driven wheel. The first end of the support rod is slidably connected to the support member, and the sliding direction of the first end of the support rod is collinear with the sliding direction of the second end of the first transmission rod relative to the support member.

[0020] Preferably, the first end of the support rod and the second end of the first transmission rod are slidably connected to different positions of the support member.

[0021] In this way, the auxiliary transmission component can provide auxiliary support to the support rod, thereby enhancing the support capacity of the support rod.

[0022] In one possible implementation, the transmission mechanism includes a second transmission rod and a third transmission rod. The first end of the second transmission rod is fixedly mounted on the axle of the driven wheel, the second end of the second transmission rod is rotatably connected to the first end of the third transmission rod, and the second end of the third transmission rod is rotatably connected to the support rod.

[0023] In this way, the driven wheel can drive the second transmission rod to rotate, the second transmission rod can drive the third transmission rod connected to it to move, and the third transmission rod can drive the support rod to move.

[0024] In one possible implementation, the auxiliary transmission assembly further includes a second auxiliary rod, the first end of which is rotatably connected to the slide groove, and the second end of which is rotatably connected to the first end of the support rod, both of which are slidably connected to the support member.

[0025] In this way, the second auxiliary rod can cooperate with the movement of the support rod and provide auxiliary support for the support rod, sharing the force on the support rod, thereby extending the service life of the first transmission rod.

[0026] In one possible implementation, the slide includes a first slide and a second slide that are spaced apart; the first end of the first auxiliary rod is slidably disposed in the first slide, and the second end of the third transmission rod is rotatably connected to the second end of the support rod, and both are slidably disposed in the second slide;

[0027] The first end of the second slide is rotatably connected to the base, and the second end of the second slide is a movable end.

[0028] The second auxiliary rod works in conjunction with the support rod to provide support to the support component;

[0029] Preferably, the flexible screen support device further includes an elastic support device disposed on the base, and the elastic support device is connected to the second end of the second slide groove.

[0030] In this way, the elastic support device can provide support for the second slide, reduce the force on the second slide, and extend its service life.

[0031] In one possible implementation, the second end of the third transmission rod is rotatably connected to the first end of the support rod, and both are slidably connected to the support member; the second end of the support rod is slidably disposed in the groove.

[0032] The first end of the second auxiliary rod and the first end of the first auxiliary rod are located at different positions in the slide.

[0033] Thus, driven by the third transmission rod, the second end of the support rod slides in the groove, and the first end of the support rod slides on the support member, causing the support member to move.

[0034] In one possible implementation, the auxiliary transmission assembly includes an auxiliary wheel, with the driven wheel and the auxiliary wheel forming a transmission; the second end of the support rod is fixedly mounted on the axle of the auxiliary wheel, and the auxiliary wheel is configured to drive the support rod to rotate under the drive of the driven wheel;

[0035] Preferably, the auxiliary transmission assembly includes a second auxiliary rod, the first end of which is slidably connected to the slide groove, and the second end of which is rotatably connected to the first end of the support rod, and both are slidably connected to the support member;

[0036] Preferably, the slide includes a first slide and a second slide that are spaced apart, the first end of the first auxiliary rod is slidably disposed in the first slide, and the first end of the second auxiliary rod is slidably connected in the second slide.

[0037] In this way, the driven wheel can drive the auxiliary wheel to rotate, and the auxiliary wheel can drive the support rod to rotate. During the rotation of the support rod, the first end of the support rod can slide relative to the support member and apply a supporting force to the support member.

[0038] In one possible implementation, the support mechanism further includes a slider connected to the support member. The slider is slidably mounted on the base, and the sliding direction of the slider relative to the base is the same as the moving direction of the support member.

[0039] In this way, when the first transmission rod rotates, it can drive the sliding component to slide relative to the base, and at the same time, the support component will move accordingly; the transmission structure is simple and reliable, and easy to install.

[0040] A second aspect of this application provides a display device, including a flexible screen and a flexible screen support device according to any of the embodiments of the first aspect described above.

[0041] The display device provided in this application embodiment includes a flexible screen support device. When the flexible screen support device enters a second state, the support mechanism can support the flexible screen under the drive of the transmission mechanism. When the flexible screen support device transitions from the second state to the first state, the support mechanism can detach from the flexible screen under the drive of the transmission mechanism. When the support mechanism supports the flexible screen, it is in direct contact with the flexible screen and can support the stress points of the flexible screen. Therefore, when the stress points of the flexible screen are subjected to gravity and pressing forces during click operations, the presence of the support mechanism can greatly reduce the deformation of the stress points of the flexible screen, thereby ensuring the service life of the flexible screen.

[0063] In related technologies, a display device may include a mounting base and a flexible screen. The flexible screen is mounted on a support, and the mounting base has mechanical strength and can support the flexible screen. The flexible screen mounted on the mounting base typically has two states: a first state (rolled up) and a second state (unrolled). When in use, the flexible screen is in the second state.

[0064] However, rollable display devices using flexible screens still have some problems. Due to the nature of the flexible screen material, when a rollable display device with a flexible screen is unfolded, it is affected by gravity and the pressing force during click operations. The stressed areas of the flexible screen will collapse, and prolonged use will cause irreversible deformation of the flexible screen, affecting its use. Therefore, how to avoid or mitigate this deformation of flexible screens has always been an urgent problem to be solved.

[0065] To address the aforementioned issues, this application provides a flexible screen support device and a display device. The flexible screen support device is applied in the display device and includes a driving mechanism, a transmission mechanism, and a support mechanism. The driving mechanism is connected to the support mechanism via the transmission mechanism and is configured to move the support mechanism closer to or further away from the flexible screen via the transmission mechanism. During operation, the flexible screen support device has a first state and a second state. When the flexible screen support device enters the second state, the support mechanism supports the flexible screen under the drive of the transmission mechanism. When the flexible screen support device transitions from the second state to the first state, the support mechanism detaches from the flexible screen under the drive of the transmission mechanism. When the support mechanism supports the flexible screen, it provides support to the stress points of the flexible screen. Therefore, when the stress points of the flexible screen are subjected to gravity and pressing forces during click operations, the presence of the support mechanism can significantly reduce the deformation of the stress points, thereby ensuring the service life of the flexible screen.

[0066] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, 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.

[0067] like Figure 1 As shown, the display device includes a flexible screen 500 and a flexible screen support device, with the flexible screen 500 located on the support surface of the flexible screen support device. The support surface of the flexible screen support device can contact the flexible screen 500, providing support for the flexible screen 500.

[0068] In the display device, multiple flexible screen support devices can be set up, so that multiple support surfaces of multiple flexible screen support devices can contact and support the flexible screen 500. This is because in actual use, there will be multiple stress points on the flexible screen 500, and the support effect of a single flexible screen support device on the flexible screen 500 is limited.

[0069] The display device uses a rollable flexible screen 500, which is mounted on a mounting bracket 600. The rollable flexible screen 500 mainly includes a bending area 510 and two planar areas. The two planar areas are a first planar area 520 and a second planar area 530, and the first planar area 520 and the second planar area 530 are connected by the bending area 510.

[0070] The first planar region 520 and the second planar region 530 of the flexible screen 500 can be planar; the first planar region 520 and the second planar region 530 can be arranged parallel to each other, and the bending region 510 of the flexible screen 500 can be bent. During the rolling process of the flexible screen 500, the bending region 510 can transform into a planar region, and the planar region can also transform into a bending region 510.

[0071] It should be noted that the display area of ​​the first plane region 520 is the main display area of ​​the display device. Pressing operations can be performed in this area to enable the use of the display device. Compared to the second plane region 530, the first plane region 520 is the main stress-bearing area. Therefore, the flexible screen support device needs to support the stress points on the first plane region 520 to reduce the deformation of the flexible screen 500 at these stress points, thus not affecting the normal service life of the flexible screen 500. Therefore, in the following description, descriptions of actions such as "supporting," "moving away from," or "moving closer to" the components in the flexible screen support device are based on the first plane region 520 of the flexible screen 500 as the reference point.

[0072] It should be noted that after force is applied to the flexible screen 500, the flexible screen 500 can be rolled in two different directions; thus, during the rolling process of the flexible screen 500, the flexible screen support device will have two different states: the first state and the second state.

[0073] When the second planar region 530 curls towards the first planar region 520, the area of ​​the second planar region 530 decreases, while the area of ​​the first planar region 520 increases. At this time, driven by the flexible screen 500, the transmission mechanism 200 can drive the support mechanism 300 to directly contact the flexible screen 500, thereby supporting the flexible screen 500. During this process, the flexible screen support device is in the second state.

[0074] When the first planar region 520 curls towards the second planar region 530, the area of ​​the first planar region 520 decreases, and the area of ​​the second planar region 530 increases. At this time, driven by the flexible screen 500, the transmission mechanism 200 can drive the support mechanism 300 to separate from the flexible screen 500, and the support mechanism 300 can no longer support the flexible screen 500. During this process, the flexible screen support device is in the first state.

[0075] The technical solution of this application and how it solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0076] The following combination Figures 1-4The flexible screen support device provided in the embodiments of this application will be described in detail.

[0077] The flexible screen support device includes a drive mechanism 100, a transmission mechanism 200, and a support mechanism 300. The drive mechanism 100 is connected to the support mechanism 300 via the transmission mechanism 200, and the drive mechanism 100 is configured to drive the support mechanism 300 to move via the transmission mechanism 200. The power for the drive mechanism 100 can come from the winding action of the flexible screen 500. During the winding and unfolding process, the flexible screen 500 provides power to the drive mechanism 100, which transmits the power through the transmission mechanism 200 to the support mechanism 300, causing the support mechanism 300 to move and thus supporting the flexible screen 500.

[0078] Specifically, the support mechanism 300 is provided with a support surface, which is used to support the flexible screen 500. When the drive mechanism 100 drives the support mechanism 300 to move through the transmission mechanism 200, the support surface on the support mechanism 300 will also move accordingly, thereby enabling the support member 310 to support the flexible screen 500.

[0079] As described above, when the flexible screen support device is used to support the flexible screen 500 of the display device, the flexible screen support device has two states: a first state and a second state. These two states have been described above and will not be repeated here.

[0080] The support mechanism 300 is configured to support the flexible screen 500 under the drive of the transmission mechanism 200 when the flexible screen support device is in the second state, and is configured to disengage from the flexible screen 500 under the drive of the transmission mechanism 200 when the flexible screen support device is in the first state.

[0081] When the flexible screen support device moves from the first state to the second state, during the unfolding of the flexible screen 500, the transmission mechanism 200 can drive the support mechanism 300 to move, and make the support mechanism 300 gradually approach the flexible screen 500 and come into contact with the flexible screen 500, thereby achieving support for the stress points of the flexible screen 500.

[0082] like Figure 1 As shown in the figure, the flexible screen support device is in the second state, and the support mechanism 300 comes into contact with the flexible screen 500 and supports the flexible screen 500.

[0083] When the flexible screen support device moves from the second state to the first state, during the winding process of the flexible screen 500, the transmission mechanism 200 can drive the support mechanism 300 to move, causing the support mechanism 300 to separate from the flexible screen 500 and gradually move away from the flexible screen 500. At this time, the support mechanism 300 removes its support for the stress points of the flexible screen 500.

[0084] like Figure 2 As shown in the figure, the flexible screen support device is in the first state, and the support mechanism 300 has detached from the flexible screen 500.

[0085] Below, in conjunction with Figures 1-4 The structure of the flexible screen support device provided in the embodiments of this application will be further described.

[0086] In this embodiment of the application, the flexible screen support device also includes a base 400, a drive mechanism 100, a transmission mechanism 200 and a support mechanism 300 of the flexible screen support device, which are mounted on the base 400. The base 400 provides support for these mechanisms, and the base 400 is mounted on the mounting frame 600.

[0087] In addition, the drive mechanism 100 includes a drive wheel 110 and a driven wheel 120. The drive wheel 110 and the driven wheel 120 are linked and both are mounted on the base 400. The driven wheel 120 is connected to the transmission mechanism 200. The drive wheel 110 mounted on the base 400 can drive the driven wheel 120 to rotate, and the driven wheel 120 can provide power to the transmission mechanism 200.

[0088] With this configuration, the transmission structure of the drive wheel 110 and the driven wheel 120 is simple and reliable, which facilitates installation on the base 400 and reduces installation and maintenance costs.

[0089] It should be noted that the drive wheel 110 can be installed corresponding to the bending area 510 of the flexible screen 500. The drive wheel 110 can form a transmission structure with the flexible screen 500, and the drive wheel 110 can be directly driven by the winding action of the flexible screen 500. Specifically, during the winding process, the flexible screen 500 drives the drive wheel 110 to rotate, which in turn drives the driven wheel 120 to rotate. Specifically, the drive wheel 110 and the driven wheel 120 can be connected by a transmission belt or a transmission chain.

[0090] Furthermore, the support mechanism 300 includes a support member 310, which has a support plane 311 on the side facing the flexible screen 500. The support member 310 moves in a direction perpendicular to the support plane 311 under the drive of the transmission mechanism 200. Thus, when the support member 310 approaches the flexible screen 500, the support plane 311 can contact and support the flexible screen 500. Optionally, a flexible pad can be installed on the support plane 311 to ensure that the support member 310 does not damage the flexible screen 500 when supporting it.

[0091] Furthermore, in the transmission structure, the transmission mechanism 200 includes a first transmission rod 210, the first end of which is connected to the axle of the driven wheel 120, and the second end of which is slidably connected to the support member 310; the sliding direction of the second end of the first transmission rod 210 is parallel to the extension direction of the support plane 311.

[0092] With this configuration, when the driven wheel 120 rotates, the first transmission rod 210 connected to the axle of the driven wheel 120 also rotates accordingly. The second end of the first transmission rod 210 rotates around its first end. During rotation, the second end of the first transmission rod 210 slides relative to the support member 310, causing the support member 310 to move closer to or further away from the flexible screen 500. Specifically, when the first transmission rod 210 rotates around its first end, its second end moves closer to or further away from the flexible screen 500. When the second end of the first transmission rod 210 moves away from the flexible screen 500, the first transmission rod 210 also moves away from the flexible screen 500; when the second end of the first transmission rod 210 moves closer to the flexible screen 500, the first transmission rod 210 also moves closer to the flexible screen 500. The presence of the first transmission rod 210 simplifies the structure of the transmission mechanism 200 and makes the transmission process simple and reliable.

[0093] Additionally, a mounting groove 312 can be provided on the support member 310, and the second end of the first transmission rod 210 is located in the mounting groove 312, and can slide in the mounting groove 312 along the extension direction of the support plane 311. Specifically, a roller can be installed on the second end of the first transmission rod 210 and placed in the mounting groove 312. In this way, the second end of the first transmission rod 210 is mounted in the mounting groove 312 through the roller, thereby reducing wear during the sliding process when the second end of the first transmission rod 210 slides in the mounting groove 312, and extending the service life of the first transmission rod 210 and the support member 310.

[0094] For example, the support mechanism 300 further includes a slider 320, which is connected to the support member 310. The slider 320 is slidably mounted on the base 400, and the sliding direction of the slider 320 relative to the base 400 is the same as the moving direction of the support member 310. The sliding direction of the slider 320 relative to the base 400 determines the moving direction of the support member 310. The base 400 may be provided with a sliding groove, and the slider 320 may be placed in the sliding groove, thereby limiting the sliding direction of the slider 320 relative to the base 400; in addition, the support member 310 may be symmetrically arranged on both sides of the sliding groove with the sliding groove as the center of symmetry.

[0095] With this configuration, the support member 310 is mounted on the base 400 via the sliding member 320. When the first transmission rod 210 rotates, it can drive the sliding member 320 to slide relative to the base 400, and at the same time, the support member 310 will move accordingly. The transmission structure is simple, reliable, and easy to install.

[0096] Furthermore, the transmission mechanism 200 also includes a slide groove 230, which is disposed on the base 400. The transmission mechanism 200 includes a first auxiliary rod 220, the first end of which is slidably disposed in the slide groove 230, and the second end of which is rotatably connected to the second end of the first transmission rod 210, and both are slidably connected to the support member 310.

[0097] With this configuration, the first end of the first auxiliary rod 220 can slide relative to the slide groove 230, and the second end of the first auxiliary rod 220 can slide relative to the support member 310. The first auxiliary rod 220 can cooperate with the movement of the first transmission rod 210 and provide auxiliary support for the first transmission rod 210, sharing the force on the first transmission rod 210, thereby extending the service life of the first transmission rod 210.

[0098] Furthermore, the extension direction of the slide groove 230 can be parallel to the extension direction of the support plane 311; the position height of the slide groove 230 can be consistent with the position height of the center of the driven wheel 120; and the length of the first auxiliary rod 220 can be consistent with the length of the first transmission rod 210. This arrangement ensures that the first auxiliary rod 220 and the first transmission rod 210 are subjected to uniform force.

[0099] Furthermore, the transmission mechanism 200 also includes an auxiliary transmission assembly 240. As the main support member 310, the support rod 241 needs to withstand a certain amount of pressure. If only the first transmission rod 210 applies support force to the support rod 241, the support capacity of the support rod 241 cannot be adequately guaranteed. Therefore, an auxiliary transmission assembly 240 is added, which cooperates with the first transmission rod 210. With this configuration, the auxiliary transmission assembly 240 can provide auxiliary support to the support rod 241, thereby enhancing its support capacity.

[0100] The following is combined Figures 1-4 The structure of the auxiliary transmission assembly 240 will be described.

[0101] The driven wheel 120 is linked to the auxiliary transmission assembly 240, and at least a portion of the auxiliary transmission assembly 240 is slidably connected to the support member 310. The auxiliary transmission assembly 240 is configured to be driven by the driven wheel 120 when the driven wheel 120 rotates, thereby moving the support member 310. Thus, when the driven wheel 120 rotates, the auxiliary transmission assembly 240 can generate corresponding movement and drive the support member 310 to move.

[0102] Specifically, the auxiliary transmission assembly 240 includes a support rod 241, which is connected to the driven wheel 120. The first end of the support rod 241 is slidably connected to the support member 310, and the sliding direction of the first end of the support rod 241 is collinear with the sliding direction of the second end of the first transmission rod 210 relative to the support member 310.

[0103] With this configuration, when the driven wheel 120 rotates, the support rod 241 can slide relative to the support member 310 and apply a corresponding supporting force to the support member 310; in addition, a mounting groove 312 can be provided on the support rod 241, and the first end of the support rod 241 and the second end of the first transmission rod 210 can slide simultaneously in the mounting groove 312.

[0104] Specifically, the first end of the support rod 241 and the second end of the first transmission rod 210 are slidably connected to different positions of the support member 310.

[0105] With this configuration, the first end of the support rod 241 and the second end of the first transmission rod 210 can support two different positions of the support member 310, ensuring that the support member 310 is subjected to uniform force and improving the support capacity of the support rod 241.

[0106] In one embodiment, such as Figure 2 and Figure 3 As shown, the transmission mechanism 200 also includes a second transmission rod 250 and a third transmission rod 260. The first end of the second transmission rod 250 is fixedly mounted on the axle of the driven wheel 120. The second end of the second transmission rod 250 is rotatably connected to the first end of the third transmission rod 260. The second end of the third transmission rod 260 is rotatably connected to the support rod 241.

[0107] With this configuration, when the driven wheel 120 rotates, it can drive the second transmission rod 250 to rotate, which in turn drives the connected third transmission rod 260 to move. The third transmission rod 260 can then drive the support rod 241 to move, causing the first end of the support rod 241 to slide relative to the support member 310, thereby enabling the support rod 241 to provide support for the support member 310.

[0108] Furthermore, the auxiliary transmission assembly 240 also includes a second auxiliary rod 242. The first end of the second auxiliary rod 242 is rotatably connected to the slide groove 230, and the second end of the second auxiliary rod 242 is rotatably connected to the first end of the support rod 241, and both are slidably connected to the support member 310.

[0109] With this configuration, the second auxiliary rod 242 can rotate relative to its first end, and its second end can slide relative to the support member 310. Therefore, the second auxiliary rod 242 can cooperate with the movement of the support rod 241 and provide auxiliary support for the support rod 241, sharing the force on the support rod 241, thereby extending the service life of the first transmission rod 210.

[0110] like Figure 2 As shown, the slide 230 includes a first slide 231 and a second slide 232 that are spaced apart; the first end of the first auxiliary rod 220 is slidably disposed in the first slide 231, and the second end of the third transmission rod 260 is rotatably connected to the second end of the support rod 241, and both are slidably disposed in the second slide 232.

[0111] The first slide groove 231 and the second slide groove 232 can be arranged collinearly, and the first slide groove 231 and the second slide groove 232 can be located on both sides of the sliding rod respectively; the first slide groove 231 and the second slide groove 232 are used to install the rod, thereby restricting the movement of the rod and providing support for the rod.

[0112] The first end of the second slide groove 232 is rotatably connected to the base 400, and the second end of the second slide groove 232 is a movable end. The first end of the second auxiliary rod 242 can coincide with the position of the first end of the second slide groove 232. The second slide groove 232 can rotate relative to its first end. During rotation, the second slide groove 232 can constrain the position of the support rod 241 and also provide support for the support rod 241.

[0113] The second auxiliary rod 242 and the support rod 241 cooperate to provide support for the support member 310. It should be noted that... Figure 1 and Figure 2 The auxiliary transmission component 240 in the middle can only support the support member 310 in the cooperation of the second auxiliary rod 242 and the support rod 241. Neither of them can be missing.

[0114] Furthermore, the flexible screen support device also includes an elastic support device 243 disposed on the base 400, and the elastic support device 243 is connected to the second end of the second slide groove 232. One end of the elastic support device 243 is rotatably connected to the base 400, while the other end is connected to the second end of the second slide groove 232.

[0115] With this configuration, the elastic support device 243 can provide support for the second slide 232, reduce the force on the second slide 232, and extend its service life.

[0116] Specifically, the elastic support device 243 may be equipped with a pull rod or a spring, which is connected to the second end of the second slide groove 232 to provide support for the second slide groove 232.

[0117] like Figure 3 As shown, the second end of the third transmission rod 260 is rotatably connected to the first end of the support rod 241, and both are slidably connected to the support member 310; the second end of the support rod 241 is slidably disposed in the slide groove 230; the first end of the second auxiliary rod 242 and the first end of the first auxiliary rod 220 are respectively located at different positions in the slide groove 230.

[0118] With this configuration, driven by the third transmission rod 260, the second end of the support rod 241 slides in the slide groove 230, and the first end of the support rod 241 slides on the support member 310, thus driving the support member 310 to move.

[0119] It should be noted that the second auxiliary rod 242 and the first auxiliary rod 220 can share a slide groove 230; in addition, the slide groove 230 can also be composed of two collinear first slide grooves 231 and second slide grooves 232.

[0120] In another embodiment, such as Figure 4 As shown, the auxiliary transmission assembly 240 includes an auxiliary wheel 244, with the driven wheel 120 forming a transmission with the auxiliary wheel 244. The second end of the support rod 241 is fixedly mounted on the axle of the auxiliary wheel 244. The auxiliary wheel 244 is configured to drive the support rod 241 to rotate under the drive of the driven wheel 120. The driving wheel, driven wheel 120, and auxiliary wheel 244 can be arranged collinearly, and the driven wheel 120 and the auxiliary wheel 244 can be driven by a transmission belt or transmission chain.

[0121] With this configuration, the driven wheel 120 can drive the auxiliary wheel 244 to rotate, and the auxiliary wheel 244 can drive the support rod 241 to rotate. During the rotation of the support rod 241, the first end of the support rod 241 can slide relative to the support member 310 and apply a supporting force to the support member 310.

[0122] Specifically, the auxiliary transmission assembly 240 includes a second auxiliary rod 242, the first end of which is slidably connected to the slide groove 230, and the second end of which is rotatably connected to the first end of the support rod 241, and both are slidably connected to the support member 310.

[0123] Specifically, the slide 230 includes a first slide 231 and a second slide 232 that are spaced apart. The first end of the first auxiliary rod 220 is slidably disposed in the first slide 231, and the first end of the second auxiliary rod 242 is slidably connected in the second slide 232.

[0124] This application also provides a display device, including the aforementioned flexible screen support device. The display device can be a mobile or fixed terminal device with a flexible screen support device, such as an electronic paper device, mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, supercomputer, or navigator.
