Description

Technical Field

[0001] This application relates to the technical field of flexible screen rolling equipment, and in particular to a rolling device for the flexible screen of an electronic device. Background Art

[0002] Due to the adoption of the flexible screen structure, in the scenario of single flexible screen repair and replacement at service outlets, after the new flexible screen is attached to the mobile phone middle frame, it is necessary to activate the back glue between the inner screen of the flexible screen and the middle frame through a rolling tool to achieve the adhesion of the inner screen and the middle frame and ensure the repair quality.

[0003] In the existing methods for activating the inner screen of the flexible screen, it is usually necessary to use different rolling tools at different workstations. For example, four sets of rolling tools with different sizes are used for rolling at four workstations respectively. However, in this case, the electronic device needs to be continuously switched among different workstations, and the adaptability of the rollers for special models is not high, which affects the rolling efficiency and increases the rolling cost.

[0004] Therefore, there is an urgent need for a rolling tool that can improve the rolling efficiency and reduce the rolling cost. Summary of the Utility Model

This not only solves the problem of multiple devices participating in the current flexible screen rolling operation. Moreover, the position of the roller can be adjusted in three phases, which is applicable to the back glue areas at different positions, and can avoid weak positions such as the rotating shaft hinge mechanism and the flexible circuit board, effectively improving the rolling accuracy, saving the rolling time, and thus reducing the rolling cost.

[0015] In some feasible implementation manners, the bottom plate is provided with a first scale and a second scale; the first scale and the second scale both extend along the first direction; along the projection direction of the first support onto the bottom plate, the projection of the first nut falls on the first scale; along the projection direction of the second support onto the bottom plate, the projection of the second nut falls on the second scale. In this way, when adjusting the second nut, the adjustment distance and the final adjustment position of the second nut can be accurately determined through the second scale located below.

[0016] In some feasible implementations, the base plate is provided with a first slide rail and a second slide rail, which are arranged on a side of the base plate away from the sliding bracket and both extend in a first direction. The bottom of the first support passes through the first slide slot and is located on the first slide rail; the bottom of the second support passes through the second slide slot and is located on the second slide rail. In this way, when the sliding bracket is moved by the handle, the bottom of the first support and the bottom of the second support can move synchronously, ensuring stability during movement and improving performance.

[0017] In some feasible implementations, the flexible screen rolling device of an electronic device further includes: a first reset component and a second reset component; the first reset component is arranged in the first support, and the first reset component and the first connecting rod are arranged relative to each other, and the first reset component is configured to be squeezed by the protruding end and to move synchronously with the first connecting rod; the second reset component is arranged in the second support, and the second reset component and the second connecting rod are arranged relative to each other, and the second reset component is configured to be squeezed by the protruding end and to move synchronously with the second connecting rod; when the handle is driven to be pressed down, the first reset component and the second reset component are compressed and deformed from the initial form to the compressed form. In this way, when the driving force of the handle disappears, the handle can automatically return to its initial state, thereby improving the convenience of operation.

[0018] In some feasible implementations, the first return assembly includes a first shaft and a first return spring, the first shaft being parallel to the first connecting rod and the first return spring being sleeved on the first shaft; the second return assembly includes a second shaft and a second return spring, the second shaft being parallel to the second connecting rod and the second return spring being sleeved on the second shaft; the first return spring and the second return spring are both configured to return from a compressed state to an initial state when the drive is removed, thereby pushing the handle back to its initial state.

[0021] In some feasible implementations, the fixing assembly includes a fixing member and an adjusting member, the fixing member is located on the third slide rail, and the adjusting member is located on the fixing member; the adjusting member includes a first end, a second end, and an elastic portion; along the third direction, the elastic portion is located between the first end and the second end, and the adjusting member is connected to the fixing member via the elastic portion; the fixing assembly is configured to adjust or fix the position of the roller bracket along the second direction; in an initial state where the first end is not subjected to pressure, the first end is provided with a first distance from the surface of the fixing member, and the second end abuts against the first surface of the rolling slide bar for fixing the position of the roller bracket; in a compressed state where the first end is subjected to pressure, the first distance is reduced, the elastic portion is compressed toward one side of the first end, the elastic portion is pulled toward one side of the second end, and the second end is provided with a second distance from the first surface of the rolling slide bar for adjusting the position of the roller bracket. In this way, by providing the fixing assembly, the roller position can be adjusted along the second direction.

[0022] In some feasible implementations, the rolling bar is provided with a third scale, which is disposed on the second surface of the rolling bar. The third scale extends in the same direction as the third rail, and the first and second surfaces are opposite surfaces of the rolling bar. This allows the roller to align with the adhesive-backed area, achieving precise positioning.

[0023] In some feasible implementations, a mounting plate is provided on the sliding bracket, the mounting plate being parallel to the rolling slide bar, and the rolling slide bar being positioned between the mounting plate and the roller. An adjustment assembly comprises a knob, a screw, and an extrusion end, the extrusion end being located at the end of the screw facing away from the knob. The screw passes through the mounting plate, the knob being located at the top of the mounting plate, and the extrusion end being located at the bottom of the mounting plate. The adjustment assembly is configured to adjust the distance between the roller and the base plate under the action of a rotational force. Thus, the coordination of the mounting plate and the adjustment assembly can simplify the force transmission process.

[0024] In some feasible implementations, the central axis of the screw coincides with the central axis of the mounting plate. This way, when the knob is actuated, the force of the extrusion end acts on the center of the mounting plate, ensuring force balance on the mounting plate and effectively maintaining the stability of the entire electronic device flexible screen rolling device.

[0026] In some feasible implementation manners, at least one elastic member includes two first springs and two second springs. The two first springs are symmetrically arranged with respect to the screw, the two second springs are symmetrically arranged with respect to the screw, and the first spring is located between the second spring and the screw; wherein, the outer diameter of the second spring is larger than the outer diameter of the first spring.

[0060] Next, the technical solutions in the implementation manners of the present application will be clearly described in conjunction with the accompanying drawings in the implementation manners of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, other embodiments obtained by those of ordinary skill in the art without creative efforts all fall within the protection scope of the present application.

[0061] Hereinafter, terms such as "first", "second", etc. 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, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "plural" is two or more.

[0062] In addition, in the present application, orientation terms such as "upper", "lower", "inner", "outer", etc. are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and they can change accordingly with the change of the orientation of the components placed in the accompanying drawings.

[0063] Figure 1 It is a schematic structural diagram of a flexible screen electronic device.

[0064] Such as Figure 1As shown, the flexible screen electronic device includes a first body 10, a second body 20, a flexible screen 30, and a rotating shaft hinge mechanism 40. The first body 10 and the second body 20 are respectively arranged on both sides of the axis direction of the rotating shaft hinge mechanism 40. The first body 10 and the second body 20 are respectively connected to the rotating shaft hinge mechanism 40 and can rotate through the rotating shaft hinge mechanism 40 to reduce the included angle between the first body 10 and the second body 20 until the flexible screen electronic device presents a folded state; or increase the included angle between the first body 10 and the second body 20 until the flexible screen electronic device presents an unfolded state.

[0065] The flexible screen 30 covers the first body 10, the second body 20, and the rotating shaft hinge mechanism 40 and is respectively connected to the first body 10 and the second body 20. The rotation of the first body 10 and the second body 20 can drive the flexible screen 30 to bend or unfold. Exemplarily, the flexible screen 30 can adopt a bendable flexible screen. The flexible screen 30 has a bending area, enabling the flexible screen 30 to bend in the bending area along with the rotation of the rotating shaft hinge mechanism 40. When the flexible screen electronic device is in the unfolded state, the rotating shaft hinge mechanism 40 is also in the unfolded state. In the unfolded state, the first body 10 and the second body 20 are parallelly distributed on both sides of the rotating shaft hinge mechanism 40, and the flexible screen 30 is laid flat on the rotating shaft hinge mechanism 40 in the unfolded state. When the flexible screen electronic device is in the folded state, the rotating shaft hinge mechanism 40 is also in the folded state. In the folded state, the first body 10 and the second body 20 are oppositely distributed on both sides of the rotating shaft hinge mechanism 40, and the rotating shaft hinge mechanism 40 presses the flexible screen 30 into a water droplet shape.

[0066] During the process of inner screen lamination of the flexible screen electronic device, a rolling tool is required to activate the back glue between the inner screen and the middle frame to achieve lamination. After lamination, the first body 10 and the second body 20 can be switched between the folded state and the unfolded state through the rotating shaft hinge mechanism 40.

[0067] Figure 2 It is a schematic diagram of the position of the back glue of the inner screen of a flexible screen electronic device.

[0068] There are usually multiple areas of back glue that need to be rolled on the inner screen of the screen of the flexible screen electronic device, and the shapes and sizes of different back glue areas may vary. Such as Figure 2As shown, there are a total of 8 back glue areas that need to be rolled on the inner screen of the flexible screen electronic device, namely the first back glue area 11, the second back glue area 12, the third back glue area 13, the fourth back glue area 14, the fifth back glue area 15, the sixth back glue area 16, the seventh back glue area 17, and the eighth back glue area 18. Among them, the sizes of the first back glue area 11 to the eighth back glue area 18 are not exactly the same, which means that the widths of the back glue to be coated in the first back glue area 11 to the eighth back glue area 18, as well as the directions and pressures during rolling, are not exactly the same. And the roller sizes required for rolling different widths of back glue are not exactly the same. For example, when the back glue area is relatively wide, a roller with a larger size can be used, such as the second back glue area 12; when the back glue area is relatively narrow, a roller with a smaller size can be used, such as the first back glue area 11.

[0069] Currently, the rolling operation of flexible screen electronic devices usually requires different steps to cooperate to complete, and each step needs to be implemented at different workstations. And the rolling equipment on different workstations is usually set for special models. Take Figure 2 the first back glue area 11 to the eighth back glue area 18 shown as an example, and perform the rolling operation of the entire flexible screen in the order of the following first step to the fourth step.

[0070] First step: Place the flexible screen electronic device at the first workstation and use an arc length y-direction rolling device to perform a rolling operation on the first back glue area 11 and the seventh back glue area 17.

[0071] Second step: Place the flexible screen electronic device after completing the first step at the second workstation and use an axial y-direction rolling device to perform a rolling operation on the third back glue area 13 and the fifth back glue area 15.

[0072] Third step: Place the flexible screen electronic device after completing the second step at the third workstation and use a sub-frame x-direction rolling device to perform a rolling operation on the second back glue area 12 and the fourth back glue area 14.

[0073] Fourth step: Place the folded electronic device after completing the third step at the fourth workstation and use a main-frame x-direction rolling device to perform a rolling operation on the sixth back glue area 16 and the eighth back glue area 18. Among them, the first workstation, the second workstation, the third workstation, and the fourth workstation are four different workstations respectively.

[0074] Since the widths of the first adhesive area 11, the third adhesive area 13, the fifth adhesive area 15, the sixth adhesive area 16, the seventh adhesive area 17 and the eighth adhesive area 18 are the same, when rolling, rollers with the first width can be used, and the pressure during rolling can be the first pressure. The width of the fourth adhesive area 14 is greater than the widths of the first adhesive area 11, the third adhesive area 13, the fifth adhesive area 15, the sixth adhesive area 16, the seventh adhesive area 17 and the eighth adhesive area 18. When rolling, rollers with the second width can be used, and the pressure during rolling can be the second pressure, where the second width is greater than the first width and the second pressure is greater than the first pressure. The width of the second adhesive area 12 is greater than the width of the fourth adhesive area 14. When rolling, rollers with the third width can be used, and the pressure during rolling can be the second pressure, where the third width is greater than the second width.

[0075] In one implementation, the first pressure can be 40 N and the second pressure can be 60 N.

[0076] During the process of rolling the flexible screen at different workstations, since the rolling equipment needs to be continuously replaced, it consumes manpower, and there are also many types of rolling equipment involved, resulting in a long rolling time and low rolling efficiency. Moreover, the use of multiple devices occupies a large amount of space and has a high cost.

[0077] In order to improve the rolling efficiency, shorten the rolling time, and reduce the rolling cost, the embodiment of the present application provides a rolling device for the flexible screen of an electronic device. The rolling device has the advantages of miniaturization, strong versatility, and low cost in view of the actual needs of limited space in service outlets and diverse maintenance models.

[0078] The following combines Figure 3 and Figure 4 to introduce the overall structure of the flexible screen rolling device provided by the embodiment of the present application.

[0079] Figure 3 is an exploded view of a rolling device for the flexible screen of an electronic device provided by the embodiment of the present application; Figure 4 is a three-dimensional schematic diagram of a rolling device for the flexible screen of an electronic device provided by the embodiment of the present application.

[0080] Combined with Figure 3 and Figure 4 As shown, in some implementations, the rolling device for the flexible screen of an electronic device may include: a bottom plate 100, a sliding bracket 200, at least one roller 300, and an adjustment component 400. The rolling device for the flexible screen of an electronic device provided by the embodiment of the present application is used to roll the flexible screen of an electronic device.

[0081] In some embodiments, the bottom plate 100 is used to carry the electronic device to be rolled.

[0082] In one example, the electronic device may be placed directly on the base plate 100 . In this example, the bottom surface of the electronic device is in contact with the top surface of the base plate 100 .

[0083] In another example, the electronic device may be connected to the base plate 100 via a connector. In this example, the connector is located between the top surface of the base plate 100 and the bottom surface of the electronic device. Of course, in other examples, the electronic device may be installed on the base plate 100 in other forms or with other components. The embodiments of this application do not specifically limit the installation method of the electronic device.

[0084] It is worth noting that no matter which installation method is adopted, the top surface of the base plate 100 and the top surface of the electronic device face the same direction.

[0085] In some embodiments, the sliding bracket 200 is slidably connected to the base plate 100. The base plate 100 is provided with a sliding groove for sliding the sliding bracket 200. The sliding bracket 200 can slide in the sliding groove of the base plate 100 along a first direction. The first direction can be the width direction of the base plate 100.

[0086] To facilitate the description of the positions of the various components in the rolling device for the flexible screen of an electronic device, the embodiment of the present application exemplarily establishes a three-dimensional coordinate system on the base plate 100, wherein the x-axis direction is the width direction of the base plate 100, the y-axis direction is the length direction of the base plate 100, and the z-axis direction is the height direction of the base plate 100. Similarly, after the electronic device is mounted on the base plate 100, the x-axis direction is also the width direction of the flexible screen, the y-axis direction is also the length direction of the flexible screen, and the z-axis direction is also the height direction of the flexible screen.

[0087] In this way, the sliding groove extends along the x-axis direction, and the sliding bracket 200 can slide on the base plate 100 along the x-axis direction.

[0088] In some embodiments, at least one roller 300 is disposed on the sliding bracket 200. When the sliding bracket 200 slides on the base plate 100 along the x-axis direction, the sliding bracket 200 can drive the roller 300 to slide along the x-axis direction.

[0089] The roller 300 includes a roller bracket 301 and a roller 302. The roller bracket 301 is connected to the sliding bracket 200 and can slide on the sliding bracket 200 along the second direction. For example, the roller bracket 301 can be a frame structure with an opening, and the roller 302 is disposed in the opening. The roller 302 can be a cylindrical structure. When the roller 302 rotates relative to the roller bracket 301, it rotates around the central axis of the roller 302.

[0090] The second direction can be the length direction of the bottom plate 100, that is, the y-axis direction, and the second direction is perpendicular to the first direction. In this way, the rolling device can not only enable the sliding bracket 200 to drive the roller 300 to slide along the x-axis direction, but the roller 300 itself can also slide on the sliding bracket 200 along the y-axis direction.

[0091] The drum 302 faces the bottom plate 100. In this way, when the bottom plate 100 carries an electronic device, the drum 302 of the roller 300 can move along the x-axis direction and the y-axis direction on the flexible screen of the electronic device.

[0092] In some embodiments, the adjusting component 400 is arranged on the sliding bracket 200. The adjusting component 400 can drive the roller 300 to move along the third direction, so as to adjust the distance between the roller 300 and the bottom plate 100. Wherein, the third direction is the thickness direction of the bottom plate 100, and the third direction is perpendicular to both the first direction and the second direction. That is to say, the roller 300 can be driven by the adjusting component 400 to move along the z-axis direction.

[0093] Exemplarily, the adjusting component 400 can drive the roller 300 to move towards the direction close to the bottom plate 100, and the adjusting component 400 can also drive the roller 300 to move towards the direction away from the bottom plate 100.

[0094] By setting the adjusting component 400, the position of the roller 300 along the z-axis direction is adjusted. This also makes it possible that in the rolling device provided by the embodiment of the present application, the roller 300 can move in three directions of the x-axis, y-axis and z-axis. The roller 300 adapts to the flatness difference, and better rolls the back glue area of the flexible screen of the electronic device to ensure the rolling accuracy. This not only solves the problem of multiple devices participating in the current flexible screen rolling operation. Moreover, the position of the roller 300 can be adjusted in three phases, which is applicable to the back glue areas at different positions, and can avoid weak positions such as the rotating shaft hinge mechanism and the flexible circuit board, effectively improving the rolling accuracy, saving the rolling time. At the same time, since the problem of multiple devices participating is solved, the manual participation time and the rolling cost are also reduced, improving the user experience.

[0095] In some implementation manners, the roller bracket 301 is detachably connected to the sliding bracket 200. In this way, when rolling the flexible screen of the electronic device, the roller 300 with the corresponding width can be replaced according to the width of different back glue areas, so as to improve the adaptability of the rolling device and the rolling efficiency.

[0096] For the convenience of describing the working process of the rolling device, hereinafter, taking the number of rollers 300 as two as an example, the rolling process of the back glue area is exemplarily described. The two rollers 300 at this time are not the total number of rollers 300, but the number of rollers 300 participating in the work at the same time. The remaining rollers 300 can be replaced in different scenarios, improving the adaptability of the rollers 300.

[0097] Optionally, in the embodiments of the present application, the number of rollers 300 is at least three, and at least two rollers 300 have different sizes.

[0098] For example, when rolling the first adhesive area 11 to the eighth adhesive area 18 in Figure 2 the full-screen rolling of the flexible screen of the electronic device can be achieved through the following steps.

[0099] Step 5: Use two rollers 300 with the first width to roll the first adhesive area 11 and the seventh adhesive area 17.

[0100] Step 6: Adjust the position of the roller 300 along the y-axis direction, and still use two rollers 300 with the first width to roll the third adhesive area 13 and the fifth adhesive area 15.

[0101] Step 7: Adjust the position of the electronic device, and at the same time adjust the position of the roller 300 along the y-axis direction to roll the sixth adhesive area 16 and the eighth adhesive area 18.

[0102] Step 8: Replace the two rollers 300 with the first width with a roller 300 with the second width and a roller 300 with the third width, and adjust the positions of the two rollers 300 in the y-axis direction so that the projection of the roller 300 with the second width onto the bottom plate 100 falls within the fourth adhesive area 14, and the projection of the roller 300 with the third width onto the bottom plate 100 falls within the second adhesive area 12, so as to achieve the simultaneous rolling of the fourth adhesive area 14 and the second adhesive area 12.

[0103] It should be noted that in the above steps 5 to 8, the rolling operation on the adhesive area is realized by sliding the roller 300 along the x-axis direction through the sliding bracket 200. At the beginning of the rolling operation, the roller 302 of the roller 300 can be abutted against the flexible screen of the electronic device through the adjusting component 400. In this example, there is no limitation on the execution order between steps 5 to 8 and the foregoing steps 1 to 4.

[0104] In one implementation, the width of the roller 300 can include four types. Four rollers 300 with different widths can meet the rolling requirements of different adhesive areas. In this way, the width of the roller 300 is optional, and a set of rollers 300 can be applied to multiple models, reducing costs.

[0105] For example, the four width gradients of the roller 300 can be 8mm, 15mm, 25mm and 35mm respectively. Among them, the positioning benchmarks of different rollers 300 are the same, and with a detachable structure, the rollers 300 can be made universal for different models.

[0106] In some implementations, in combination withFigure 3 and Figure 4 As shown in Figure 4 , the sliding grooves provided on the bottom plate 100 include a first sliding groove 101 and a second sliding groove 102. The first sliding groove 101 and the second sliding groove 102 are provided on opposite sides of the bottom plate 100 along the second direction, and both the first sliding groove 101 and the second sliding groove 102 extend along the first direction.

[0107] The sliding bracket 200 includes a first support 201 and a second support 202. The first support 201 extends along the third direction and can slide within the first sliding groove 101. The second support 202 extends along the third direction and can slide within the second sliding groove 102.

[0108] In this way, through the sliding operations of the first support 201 and the second support 202, the sliding bracket 200 can be made to drive the roller 300 to move along the x-axis direction.

[0109] By providing the first support 201 and the second support 202 on opposite sides of the bottom plate 100, during the process of the entire sliding bracket 200 being stressed, the acting force is evenly transmitted to the first support 201 and the second support 202. This ensures the overall stability of the sliding bracket 200 during the synchronous movement of the first support 201 and the second support 202, providing a stable foundation for subsequent rolling operations.

[0110] In some implementation manners, as shown in Figure 3 and Figure 4 the flexible screen of the electronic device further includes a driving component 500.

[0111] In some embodiments, the driving component 500 can be provided on the sliding bracket 200. The driving component 500 is used to drive the sliding bracket 200 to slide along the first direction on the bottom plate 100. Optionally, the driving component 500 can drive the first support 201 to slide within the first sliding groove 101, and the driving component 500 can also drive the second support 202 to slide within the second sliding groove 102. Among them, since the driving component 500 is provided on the sliding bracket 200, the driving component 500 can synchronously drive the first support 201 and the second support 202 to move, thereby providing the movement stability of the sliding bracket 200.

[0112] In one implementation manner, for the convenience of user operation, the driving component 500 includes a handle 501 and a cam 502.

[0113] The handle 501 can extend along the second direction, and two cams 502 are respectively connected to both ends of the handle 501. One of the cams 502 is rotatably connected to the side of the first support 201 facing away from the bottom plate 100, and the other cam 502 is rotatably connected to the side of the second support 202 facing away from the bottom plate 100.

[0114] In one example, when an external force acts on the handle 501, it can drive the first support 201 and the second support 202 to slide synchronously on the bottom plate 100 along the first direction, so as to drive the roller 300 to slide along the first direction.

[0115] By providing the handle 501, the user can grasp the handle 501 with one hand, which is convenient for the user to operate and is also conducive to simplifying the operation mode of the driving component 500.

[0116] In some embodiments, the cam 502 is a structure with a protruding end 5021. During the rotation of the cam 502, the protruding end 5021 can be rotated by the handle 501 in a direction closer to or farther from the bottom plate 100.

[0117] In one example, when the handle 501 is driven to rotate around the central axis of the cam 502 from the initial state, the protruding end 5021 can rotate in the direction towards the bottom plate 100. Here, the initial state of the handle 501 is Figure 3 and Figure 4 as shown in, the handle 501 is in a vertically arranged state.

[0118] In some implementation manners, in combination with Figure 3 and Figure 4 as shown in, the flexible screen of the electronic device further includes a limiting mechanism 600.

[0119] In some embodiments, the limiting mechanism 600 is arranged on the sliding bracket 200 and the bottom plate 100. The limiting mechanism 600 is used to limit the moving distance of the sliding bracket 200 on the bottom plate 100. Since the roller 300 is arranged on the sliding bracket 200, by limiting the moving distance of the sliding bracket 200, the rolling area of the roller 300 is further limited. By providing the limiting mechanism 600, the roller 300 is restricted to slide within the rolling area, so as to achieve the concentrated rolling of the roller 300 on the back glue area. At the same time, by adjusting the rolling area, weak positions such as the rotating shaft hinge mechanism and the flexible printed circuit (FPC) can be avoided, and the rolling accuracy can be improved.

[0120] Optionally, the limiting mechanism 600 includes a first linkage rod 601 and a second linkage rod 602. The first linkage rod 601 is arranged in the first support 201 and extends along the third direction. The first linkage rod 601 can be squeezed by the protruding end 5021 and move towards the bottom plate 100 along the third direction. The second linkage rod 602 is arranged in the second support 202 and extends along the third direction. The second linkage rod 602 can be squeezed by the protruding end 5021 and move towards the bottom plate 100 along the third direction.

[0121] In one implementation, the first support 201 is further provided with a first baffle 2012 and a first opening (not shown in the figure). The first opening faces outward, and the first baffle 2012 covers the first opening. Through the first opening, the first linkage rod 601 inside the first support 201 can be installed and adjusted. The first baffle 2012 is used to seal the first opening, which can ensure the stability of the installation environment of its internal components and also ensure aesthetics. The second support 202 is further provided with a second baffle 2022 and a second opening 202a. The second opening 202a faces outward, and the second baffle 2022 covers the second opening 202a. Through the second opening 202a, the second linkage rod 602 inside the second support 202 can be installed and adjusted. The second baffle 2022 is used to seal the second opening 202a, which can ensure the stability of the installation environment of its internal components and also ensure aesthetics.

[0122] The working state of the handle 501 will be further described below in conjunction with Figures 4 to 6 this.

[0123] Figure 5 FIG. is a schematic structural diagram of a handle in a depressed state provided by an embodiment of the present application.

[0124] As Figure 5 shown, when the handle 501 is in the depressed state, the handle 501 is horizontally arranged. When the handle 501 is driven to rotate from the initial state around the central axis of the cam 502 to the depressed state, the first linkage rod 601 is squeezed by the protruding end 5021 of the cam 502 and moves along the third direction towards the bottom plate 100, and the second linkage rod 602 is squeezed by the protruding end 5021 of the cam 502 and moves along the third direction towards the bottom plate 100. Among them, when the handle 501 is driven to rotate from the initial state to the depressed state, the first linkage rod 601 and the second linkage rod 602 are synchronously squeezed and moved by the protruding end 5021.

[0125] In some embodiments, the limiting mechanism 600 further includes a first limiting component 603 and a second limiting component 604.

[0126] Both the first limiting component 603 and the second limiting component 604 are located on both sides of the bottom plate 100, and the first limiting component 603 and the first sliding groove 101 are arranged on the same side of the bottom plate 100, and the second limiting component 604 and the second sliding groove 102 are arranged on the same side of the bottom plate 100. Among them, the first limiting component 603 is used to limit the moving distance of the first linkage rod 601 along the first direction. The second limiting component 604 is used to limit the moving distance of the second linkage rod 602 along the first direction.

[0127] Figure 6 FIG. is a comparative schematic diagram of the first linkage rod and the second linkage rod before and after being limited provided by an embodiment of the present application. Among them, Figure 6In (a), it is a schematic structural diagram of the first linkage rod and the second linkage rod before being limited and the first limiting component and the second limiting component. Figure 6 In (b), it is a schematic structural diagram of the first linkage rod and the second linkage rod after being limited and the first limiting component and the second limiting component.

[0128] Combined with Figure 4 and Figure 6 As shown in (a), in the initial state where the handle 501 is not driven, the first linkage rod 601 is located inside the first support 201 and does not extend out of the first support 201. The height of the bottom of the first linkage rod 601 is higher than the height of the first limiting component 603. At this time, the bottom of the first linkage rod 601 is located above the first limiting component 603. Similarly, in the initial state where the handle 501 is not driven, the second linkage rod 602 is located inside the second support 202 and does not extend out of the second support 202. The height of the bottom of the second linkage rod 602 is higher than the height of the second limiting component 604. At this time, the bottom of the second linkage rod 602 is located above the second limiting component 604. The first support 201 and the second support 202 are in an unrestricted state.

[0129] Combined with Figure 5 and Figure 6 As shown in (b), when the handle 501 is under the action of a driving force, the protruding end 5021 is driven to rotate towards the direction close to the bottom plate 100, pushing the first linkage rod 601 and the second linkage rod 602 to move towards the bottom plate 100 until the handle 501 is in a pressed state. During the process of the handle 501 changing from the initial state to the pressed state, the protruding end 5021 can move towards the tops of the first linkage rod 601 and the second linkage rod 602. The first linkage rod 601 and the second linkage rod 602 are squeezed by the protruding end 5021 and can move towards the bottom plate 100. As the moving distance of the first linkage rod 601 and the second linkage rod 602 along the third direction increases, the first linkage rod 601 can extend out of the first support 201, and the distance between the bottom of the first linkage rod 601 and the top of the first limiting component 603 gradually decreases until the first linkage rod 601 moves into the first limiting component 603. At this time, the first limiting component 603 is used to limit the moving distance of the first linkage rod 601 along the first direction, and further limit the moving distance of the first support 201.

[0130] At the same time, the second linkage rod 602 extends out of the second support 202, the distance between the bottom of the second linkage rod 602 and the top of the second limiting component 604 gradually decreases, and the second linkage rod 602 moves into the second limiting component 604. The second limiting component 604 is used to limit the moving distance of the second linkage rod 602 along the first direction, and further limit the moving distance of the second support 202.

[0131] By setting the first linkage rod 601 and the second linkage rod 602, the first linkage rod 601 can limit the first support 201, and the second linkage rod 602 can limit the second support 202. Since the first linkage rod 601 and the second linkage rod 602 are synchronously driven by the handle 501, during the entire driving process, the moving distances of the first support 201 and the second support 202 are synchronously limited.

[0132] Continue as Figure 5 As shown, after the sliding bracket 200 drives the roller 300 to move to the rolling area, press down the handle 501 so that the first support 201 is restricted within the first limiting component 603, and the second support 202 is restricted within the second limiting component 604. By pushing or pulling the handle 501 to make the handle 501 reciprocate, the translating handle 501 drives the sliding bracket 200 to slide within the rolling area. At this time, the handle 501 is in a moving state. Among them, the roller 300 and the handle 501 reciprocate synchronously.

[0133] In one example, when pushing the handle 501, under the action of the thrust force, the handle 501 moves along the A direction. Among them, the A direction can be the reverse axis direction of the x-axis. When the handle 501 moves along the A direction, the roller 300 can be driven by the handle 501 and roll the flexible screen of the electronic device along the A direction synchronously. When pulling the handle 501, under the action of the pulling force, the handle 501 moves along the B direction. Among them, the B direction can be the positive axis direction of the x-axis. When the handle 501 moves along the B direction, the roller 300 can be driven by the handle 501 and roll the flexible screen of the electronic device along the B direction synchronously. By alternately moving the roller 300 along the A direction and the B direction, the flexible screen of the electronic device is rolled.

[0134] Optionally, during the process of the handle 501 driving the roller 300 to reciprocate, the first limiting component 603 is used to limit the moving distance of the first support 201, and the first support 201 can reciprocate within the moving distance restricted by the first limiting component 603. The second limiting component 604 is used to limit the moving distance of the second support 202, and the second support 202 can reciprocate within the moving distance restricted by the second limiting component 604. Among them, the moving distances restricted by the first limiting component 603 and the second limiting component 604 are the same. By setting the first limiting component 603 and the second limiting component 604, the rolling area of the roller 300 can be limited. By adjusting the rolling area, weak positions such as the rotating shaft hinge mechanism and FPC can be avoided, and the rolling accuracy can be improved.

[0135] In some embodiments, along the second direction, the first sliding groove 101 and the second sliding groove 102 are located between the first limiting component 603 and the second limiting component 604. In this way, the installation space can be reasonably utilized to ensure the area of the rolling area.

[0136] The following further describes the specific structure of the limiting mechanism 600 in conjunction with Figure 6 and Figure 7 The following further describes the specific structure of the limiting mechanism 600 in conjunction with

[0137] Figure 7 FIG. 9 is a schematic structural diagram of a first screw rod and a second screw rod provided by an embodiment of the present application.

[0138] In some implementation manners, in conjunction with Figure 6 Figure 7 As shown, the limiting mechanism 600 further includes a first screw rod 605 and a second screw rod 606.

[0139] The first screw rod 605 and the second screw rod 606 are respectively disposed on two sides of the bottom plate 100. Among them, the first screw rod 605 and the first sliding groove 101 are disposed on the same side of the bottom plate 100, and the first screw rod 605 extends along a first direction. The second screw rod 606 and the second sliding groove 102 are disposed on the same side of the bottom plate 100, and the second screw rod 606 extends along a second direction. The first sliding groove 101 and the second sliding groove 102 are located between the first screw rod 605 and the second screw rod 606. In this way, the installation space can be reasonably utilized to ensure the area of the rolling region.

[0140] In some embodiments, the first limiting component 603 includes two first nuts 6031, and the two first nuts 6031 are threadedly connected to the first screw rod 605. Under the action of an external force, the first nut 6031 can rotate on the first screw rod 605, and the moving distance of the first support 201 along the first direction on the bottom plate 100 can be limited by adjusting the distance between the two first nuts 6031.

[0141] The second limiting component 604 includes two second nuts 6041, and the two second nuts 6041 are threadedly connected to the second screw rod 606. Under the action of an external force, the second nut 6041 can rotate on the second screw rod 606, and the moving distance of the second support 202 along the first direction on the bottom plate 100 can be limited by adjusting the distance between the two second nuts 6041.

[0142] In conjunction with Figure 6 in (a) and Figure 7 As shown, in the initial state where the handle 501 is not driven, the distance between the bottom of the first linkage rod 601 and the upper edge of the top of the first nut 6031 can be D1. The distance between the bottom of the second linkage rod 602 and the upper edge of the top of the second nut 6041 is also D1.

[0143] In conjunction with Figure 6 in (b) and Figure 7As shown, in the state where the handle 501 is driven to be pressed down, the first linkage rod 601 can move between the two first nuts 6031, and the height of the bottom of the first linkage rod 601 is lower than the height of the upper edge of the first nut 6031. The two first nuts 6031 can limit the moving distance of the first linkage rod 601 on the bottom plate 100. At the same time, the second linkage rod 602 can move between the two second nuts 6041, and the height of the bottom of the second linkage rod 602 is lower than the height of the upper edge of the second nut 6041. The two second nuts 6041 can limit the moving distance of the second linkage rod 602 on the bottom plate 100.

[0144] In order to ensure that the first support 201 and the second support 202 have the same moving distance, corresponding adjustments are required when rotating the two first nuts 6031 and the two second nuts 6041.

[0145] By providing the first screw rod 605 and the second screw rod 606, the structure of the limiting mechanism 600 is effectively simplified, which is beneficial to simplifying the operation. The form of nuts is used for positioning the roller 300 in the x direction. The nuts are not prone to slipping when subjected to axial impact, so the stability is relatively good.

[0146] Continue as Figure 5 and Figure 7 shown, through the first limiting component 603 and the second limiting component 604, the moving distance of the sliding bracket 200 in the first direction can be adjusted. In this way, by setting the distance between the two first nuts 6031 and the distance between the two second nuts 6041, the area enclosed by the two first nuts 6031 and the two second nuts 6041 is defined as the rolling area, and the working range of the roller 300 is limited within the rolling area. In other words, the size of the rolling area can be determined by adjusting the distance between the two first nuts 6031 and the distance between the two second nuts 6041. Among them, the rolling area can be Figure 5 the area sandwiched between C1 and C2 in

[0147] In some embodiments, the positions of the first nut 6031 and the corresponding second nut 6041 in the first direction are the same.

[0148] For example, when adjusting the size of the rolling area, the first nut 6031 and the corresponding second nut 6041 are adjusted synchronously. So that the adjusted first nut 6031 and the corresponding second nut 6041 have the same coordinates on the x-axis.

[0149] Optionally, the distance between the two first nuts 6031 and the distance between the two second nuts 6041 are the same.

[0150] Next, in combination with Figure 7 and Figure 8A further introduction is made to the distance identifications of the first nut 6031 and the second nut 6041 moving along the first direction.

[0151] Figure 8 It is a schematic structural diagram of a first scale and a second scale provided by an embodiment of the present application.

[0152] Combined with Figure 7 and Figure 8 As shown, the bottom plate 100 is further provided with a first scale 103 and a second scale 104.

[0153] The first scale 103 extends along the first direction. Along the projection direction of the first support 201 onto the bottom plate 100, the projection of the first nut 6031 falls on the first scale 103. Among them, distance identifications are set on the first scale 103. That is to say, the first nut 6031 is located above the first scale 103, and there may be a distance between the bottom of the first nut 6031 and the first scale 103. When adjusting the first nut 6031, through the first scale 103 located below, the adjustment distance and the final adjustment position of the first nut 6031 can be accurately determined.

[0154] The second scale 104 extends along the first direction. Along the projection direction of the second support 202 onto the bottom plate 100, the projection of the second nut 6041 falls on the second scale 104. Among them, distance identifications are set on the second scale 104. That is to say, the second nut 6041 is located above the second scale 104, and there may be a distance between the bottom of the second nut 6041 and the second scale 104. When adjusting the second nut 6041, through the second scale 104 located below, the adjustment distance and the final adjustment position of the second nut 6041 can be accurately determined.

[0155] During the process of adjusting the two first nuts 6031 and the two second nuts 6041, the consistency of the nut positions can be maintained through the first scale 103 and the second scale 104.

[0156] It should be noted that among the distance identifications of the first scale 103 and the second scale 104, positive identifications and negative identifications can be provided. Among them, the zero positions of the first scale 103 and the second scale 104 correspond to the center O of the bottom plate 100. In this way, the center O of the bottom plate 100 can coincide with the center of the flexible screen of the electronic device installed on the bottom plate 100, so as to quickly achieve the alignment of the center, the x-axis, and the y-axis, and the operation is convenient and fast.

[0157] Next, combined with Figure 1 and Figure 9 A further description is made of the bottom surface structure of the bottom plate 100.

[0158] Figure 9This is a structural schematic diagram of a first slide rail and a second slide rail provided in an embodiment of the present application.

[0159] like Figure 9 As shown, the base plate 100 is further provided with a first slide rail 105 and a second slide rail 106. The first slide rail 105 and the second slide rail 106 are arranged on a side facing away from the sliding bracket 200. The first slide rail 105 extends in a first direction and is arranged on the same side of the base plate 100 as the first slide groove 101. The bottom of the first support 201 passes through the first slide groove 101 and is located on the first slide rail 105. In this way, the bottom of the first support 201 can slide along the first slide rail 105. The second slide rail 106 extends in the first direction and is arranged on the same side of the base plate 100 as the second slide groove 102. The bottom of the second support 202 passes through the second slide groove 102 and is located on the second slide rail 106. In this way, the bottom of the second support 202 can slide along the second slide rail 106.

[0160] In some embodiments, combined Figure 1 and Figure 9 As shown, a first L-shaped connecting block 2011 is provided at the bottom of the first support 201, and a second L-shaped connecting block 2021 is provided at the bottom of the second support 202. The first L-shaped connecting block 2011 and the second L-shaped connecting block 2021 are L-shaped. The base plate 100 also has a connecting plate 2023, which is disposed on the bottom surface of the base plate 100 along with the first and second slide rails 105, 106. The connecting plate 2023 includes a first end and a second end. The first end is disposed on the first slide rail 105 along with the first L-shaped connecting block 2011, and the second end is disposed on the second slide rail 106 along with the bottom of the second L-shaped connecting block 2021.

[0161] When the sliding bracket 200 is moved by the handle 501 , the bottom of the first support 201 and the bottom of the second support 202 can move synchronously, thereby ensuring stability during the movement and improving performance.

[0162] In some implementations, continue as Figure 3 As shown, the flexible screen rolling device of an electronic device provided in an embodiment of the present application also includes a first reset component 700 and a second reset component 800. The first reset component 700 is arranged in the first support 201, and the first reset component 700 and the first connecting rod 601 are arranged opposite to each other. The first reset component 700 can be squeezed by the protruding end 5021, and produces the same movement direction and synchronous movement as the first connecting rod 601. The second reset component 800 is arranged in the second support 202, and the second reset component 800 and the second connecting rod 602 are arranged opposite to each other. The second reset component can be squeezed by the protruding end 5021, and produces the same movement direction and synchronous movement as the second connecting rod 602.

[0163] When the handle 501 is driven by a downward pressure and the protruding end 5021 squeezes the first linkage rod 601 and the second linkage rod 602, the first reset component 700 is squeezed together with the first linkage rod 601, and the second reset component 800 is squeezed together with the second linkage rod 602. The first reset component 700 and the second reset component 800 move synchronously in the direction of the bottom plate 100. At this time, the first reset component 700 and the second reset component 800 are oppressed and deformed from the initial form to the compressed form, storing energy.

[0164] When the rolling operation ends, lift the handle 501. During the process of the handle 501 returning from the downward pressure state to the initial state, the thrust of the protruding end 5021 on one side on the first linkage rod 601 and the first limiting component 603 gradually decreases, and the thrust of the protruding end 5021 on the other side on the second linkage rod 602 and the second limiting component 604 gradually decreases. The acting force components pressing the first reset component 700 and the second reset component 800 gradually decrease. The first reset component 700 and the second reset component 800 gradually convert from the compressed form to the initial form. The energy stored when compressed can push the protruding end 5021 to drive the handle 501 to reset, so that when the driving force of the handle 501 disappears, the handle 501 can automatically return to the initial state, improving the convenience of operation.

[0165] Next, through Figure 10 the specific structures of the first reset component 700 and the second reset component 800 will be further introduced.

[0166] Figure 10 is a schematic structural diagram of a first reset component and a second reset component provided by an embodiment of the present application.

[0167] As Figure 10 shown, in one implementation, the first reset component 700 includes a first rod body 701 and a first reset spring 702. The first rod body 701 is parallel to the first linkage rod 601, and the first reset spring 702 is sleeved on the first rod body 701.

[0168] The second reset component 800 includes a first rod body 701 and a second reset spring 802. The second rod body 801 is parallel to the second linkage rod 602, and the second reset spring 802 is sleeved on the second rod body 801.

[0169] The first rod body 701 may include a protruding first top end 701a and a first bottom end 701b. During the force application process of the first reset component 700, the first top end 701a may move relative to the first bottom end 701b, and during the movement of the first top end 701a, the first reset spring 702 sleeved thereon is compressed. Among them, the first reset spring 702 is sleeved between the first top end 701a and the first bottom end 701b. Similarly, the second rod body 801 may include a protruding second top end 801a and a second bottom end 801b. During the force application process of the second reset component 800, the second top end 801a may move relative to the second bottom end 801b, and during the movement of the second top end 801a, the second reset spring 802 sleeved thereon is compressed. Among them, the second reset spring 802 is sleeved between the second top end 801a and the second bottom end 801b. Of course, in other implementation manners, the specific structures of the first reset component 700 and the second reset component 800 may be different from those introduced in this implementation manner and may also be in other forms.

[0170] By providing the first reset spring 702 and the second reset spring 802, in the state where the driving force disappears, it is no longer oppressed and gradually returns from the compressed form to the initial form. Through the elastic force of the reset spring, the reset of the handle 501 is better achieved.

[0171] The following combines Figure 4 , Figure 5 , Figure 11 and Figure 12 to further introduce the rolling rod 203 and the fixing component 204 of the sliding bracket 200.

[0172] Figure 11 FIG. is a schematic structural view of a rolling rod provided by an embodiment of the present application. Among them, Figure 11 in (a) is a bottom view of the rolling rod, Figure 11 in (b) is a three-dimensional view of the rolling rod.

[0173] Figure 12 FIG. is a schematic structural view of the fixing component provided by an embodiment of the present application. Among them, Figure 12 in (a) is a side view of a fixing component provided by an embodiment of the present application, Figure 12 in (b) is a three-dimensional schematic view of a fixing component provided by an embodiment of the present application.

[0174] Combined with Figure 4 , Figure 5 , Figure 11 and Figure 12 shown, in one implementation manner, the sliding bracket 200 further includes a rolling rod 203 and a fixing component 204.

[0175] Both ends of the rolling slide bar 203 are respectively connected to the first support 201 and the second support 202, and a third slide rail 2031 is provided on the side of the rolling slide bar 203 facing the bottom plate 100. By providing the third slide rail 2031, a sliding basis is provided for the roller 300 to slide in the second direction. The fixing component 204 is arranged on the third slide rail 2031 and can slide on the third slide rail 2031 in the second direction. The roller 300 is installed on the rolling slide bar 203 through the fixing component 204. The third slide rail 2031 can be arranged on the rolling slide bar 203 in a connected form, or can be arranged on the rolling slide bar 203 in an integral side form. The embodiment of the present application does not limit the third slide rail 2031, as long as it satisfies the sliding of the roller 300 in the second direction.

[0176] In some embodiments, the roller bracket 301 of the roller 300 is detachably connected to the fixing component 204. In this way, it is convenient to replace rollers 300 of different models to adapt to the adhesive areas with different widths and rolling requirements.

[0177] In one implementation, the roller bracket 301 and the fixing component 204 are magnetically connected. By setting the magnetic connection between the two, the rapid replacement of the roller 300 can be achieved.

[0178] In some embodiments, the fixing component 204 includes a fixing member 2041 and an adjusting member 2042. The fixing component 204 can be used to adjust the position of the roller bracket 301 in the second direction, and the fixing component 204 can also be used to fix the roller bracket 301 after the position is adjusted, so that there is no relative movement between the roller bracket 301 and the fixing component 204. The fixing member 2041 is arranged on the third slide rail 2031, and a slideway is provided on the side of the fixing member 2041 facing the third slide rail 2031. The slideway of the fixing member 2041 is adapted to the third slide rail 2031, so that the fixing member 2041 can slide on the third slide rail 2031 in the second direction. In this way, the position of the roller 300 in the second direction can be flexibly adjusted by using the cooperation of the slide rail and the slideway.

[0179] In some embodiments, the adjusting member 2042 is located on the fixing member 2041. The adjusting member 2042 includes a first end portion 2042a, a second end portion 2042b, and an elastic portion 2042c. Among them, along the third direction, the elastic portion 2042c is located between the first end portion 2042a and the second end portion 2042b. The adjusting member 2042 is connected to the fixing member 2041 through the elastic portion 2042c.

[0180] When adjusting the position of the roller bracket 301 using the adjusting member 2042, a force can be applied to the adjusting member 2042. When the adjusting member 2042 is under pressure, the roller bracket 301 can move relative to the rolling slide bar 203. When the external force disappears, the roller bracket 301 cannot move relative to the rolling slide bar 203. When the adjusting member 2042 is subjected to an external force, the external force acts on the first end portion 2042a of the adjusting member 2042.

[0181] Optionally, in an initial state where the adjusting member 2042 is not under pressure, a first distance exists between the first end 2042a and the surface of the fixing member 2041, and the second end 2042b abuts the first surface 203a of the rolling slide bar 203. In this state, the contact between the surface of the second end 2042b and the first surface 203a can frictionally fix the position of the roller 300, thereby enabling rapid positioning of the roller 300. The surface of the second end 2042b facing the first surface 203a comprises a friction surface.

[0182] When the position of the roller 300 needs to be adjusted along the second direction, pressure is applied to the first end 2042a of the adjusting member 2042. While the first end 2042a is under pressure, it moves toward the surface of the fixing member 2041, gradually reducing the first distance. As the pressure gradually increases, the first distance gradually decreases. The side of the elastic portion 2042c facing the first end 2042a is under pressure, while the side of the elastic portion 2042c facing the second end 2042b is under tension. The second end 2042b separates from the first surface 203a of the rolling slide bar 203, creating a second distance. At this point, since the second end 2042b is separated from the first surface 203a, the second end 2042b no longer serves to fix the position of the roller bracket 301. While applying pressure to the first end 2042a, the distance of the roller bracket 301 along the second direction can be adjusted by sliding the adjustment member 2042, so that the adjustment member 2042 drives the fixing member 2041, and the fixing member 2041 drives the roller bracket 301. The second distance is greater than zero and can be used to represent the magnitude of the pressure applied to the first end 2042a. The greater the second distance, the greater the pressure applied to the first end 2042a, and the smaller the second distance, the smaller the pressure applied to the first end 2042a. Thus, by providing the fixing assembly 204, the position of the roller 300 can be adjusted along the second direction.

[0183] In some embodiments, continuing as Figure 12As shown in (a), the fixing member 2041 may include a fixing bracket 2041a and a fixing block 2041b. The elastic portion 2042c is connected to the fixing bracket 2041a. When the first end portion 2042a is not stressed, there is a first distance L1 between the surface of the first end portion 2042a and the surface of the fixing block 2041b. Among them, the cross-sectional dimension of the fixing bracket 2041a is larger than the cross-sectional dimension of the fixing block 2041b. Of course, in other implementation manners, the fixing member 2041 may be set to an integral structure with a larger upper part and a smaller lower part.

[0184] The following combines Figure 2 and Figure 13 to further introduce the distance identification of the roller 300 moving along the second direction.

[0185] Figure 13 is a schematic structural diagram of a third scale provided by an embodiment of the present application.

[0186] Combined with Figure 2 and Figure 13 as shown, a third scale 2032 is provided on the rolling slide bar 203.

[0187] The third scale 2032 is provided on the second surface 203b of the rolling slide bar 203, and the extending direction of the third scale 2032 is the same as the extending direction of the third slide rail 2031. That is to say, the third scale 2032 extends along the second direction. Among them, an indicating arrow may be provided on the roller 300, so that when the roller 300 moves along the second direction, the moving distance can be clearly determined through the third scale 2032. In this way, the roller 300 can be corresponding to the back glue area to achieve precise positioning.

[0188] The second surface 203b and the first surface 203a of the rolling slide bar 203 are two opposite surfaces of the rolling slide bar 203. In this way, when adjusting the position of the roller 300 along the second direction, the adjusting member 2042 will not block the third scale 2032.

[0189] Optionally, the third scale 2032 may include a positive identification and a negative identification. The zero position of the third scale 2032 may correspond to the center O of the bottom plate 100. In this way, the zero positions of the first scale 103, the second scale 104 and the third scale 2032 all correspond to the center O position of the bottom plate 100. When the electronic device is installed on the bottom plate 100, control the center of the flexible screen of the electronic device to coincide with the center O of the bottom plate 100. In this way, the centers of the first scale 103, the second scale 104, the third scale 2032, the bottom plate 100 and the flexible screen are all in a coincident state, so as to quickly achieve the alignment of the center, x-axis, y-axis and z-axis, and the operation is convenient and fast, which is beneficial to ensuring the rolling accuracy.

[0190] The following combinesFigure 14 and Figure 15 The sliding bracket 200 and the adjustment assembly 400 are further described.

[0191] Figure 14 This is a structural diagram of a sliding bracket provided in an embodiment of the present application; Figure 15 It is a structural diagram of an adjustment component provided in an embodiment of the present application.

[0192] Combine Figure 14 and Figure 15 As shown, the sliding bracket 200 is further provided with a mounting plate 205, which is connected between the first support 201 and the second support 202, and the mounting plate 205 is parallel to the rolling slide bar 203. The rolling slide bar 203 is located between the mounting plate 205 and the roller 300.

[0193] Optionally, the mounting plate 205 extends along the second direction for mounting the adjustment assembly 400 , and the mounting plate 205 may be located near one side of the handle 501 .

[0194] In some embodiments, the adjustment assembly 400 includes a screw 402, a knob 401, and an extrusion end 403. The knob 401 and the extrusion end 403 are located at either end of the screw 402. The screw 402 is inserted through the mounting plate 205, the knob 401 is located at the top of the mounting plate 205, and the extrusion end 403 is located at the end of the screw 402 facing away from the knob 401. In other words, the extrusion end 403 is located at the bottom of the mounting plate 205. The adjustment assembly 400 is used to push the roller 300 in the third direction under the action of a rotational force, thereby adjusting the distance between the roller 300 and the base plate 100.

[0195] When the knob 401 is subjected to the rotational force, the knob 401 moves along the third direction, and the extrusion end 403 is driven by the screw 402, thereby driving the roller 300 to move along the third direction.

[0196] In one example, when the knob 401 is subjected to a positive rotational force, the knob 401 moves downward, and the extrusion end 403 squeezes the rolling slide bar 203, so that the rolling slide bar 203 drives the roller 300 to move toward the bottom plate 100, reducing the distance between the roller 300 and the bottom plate 100, thereby reducing the distance between the roller 300 and the flexible screen of the electronic device. This example is suitable for preparation work for the rolling operation of the flexible screen.

[0197] In another example, when the knob 401 is subjected to a reverse rotational force, the extrusion end 403 will move towards the end away from the rolling slider 203, so that the rolling slider 203 drives the roller 300 to move away from the bottom plate 100, increasing the distance between the roller 300 and the bottom plate 100, thereby increasing the distance between the roller 300 and the flexible screen of the electronic device. This example is applicable to completing the rolling operation of the flexible screen or adjusting the position of the roller 300 after the current back glue area has been rolled.

[0198] The top ends of the first linkage rod 601 and the first reset component 700 are abutted against one end of the mounting plate 205, and the top ends of the second linkage rod 602 and the second reset component 800 are abutted against the other end of the mounting plate 205. When the protruding end 5021 presses the first linkage rod 601, the second linkage rod 602, the first reset component 700 and the second reset component 800, the transmission of the pressing force is carried out through the mounting plate 205. By providing the mounting plate 205, the pressing force can act on the first linkage rod 601, the second linkage rod 602, the first reset component 700 and the second reset component 800 synchronously.

[0199] In one implementation, the central axis of the screw 402 coincides with the central axis of the mounting plate 205. In other words, the screw 402 is arranged at the central position of the mounting plate 205. Thus, when driving the knob 401, the acting force of the extrusion end 403 acts on the central position of the sliding bracket 200, effectively ensuring the stability of the entire flexible screen rolling device of the electronic device.

[0200] In some embodiments, continuing as Figure 14 shown, the sliding bracket 200 further includes a first sliding plate 206, a second sliding plate 207 and at least one elastic member 208. Among them, the first sliding plate 206, the elastic member 208 and the second sliding plate 207 are arranged in sequence along the third direction.

[0201] Optionally, the first sliding plate 206 is arranged below the mounting plate 205 and is located between the extrusion end 403 and the rolling slider 203. The two ends of the first sliding plate 206 are respectively connected to the first support 201 and the second support 202, and the first sliding plate 206 is arranged parallel to the mounting plate 205. At least one elastic member 208 is arranged between the first sliding plate 206 and the second sliding plate 207. Among them, the first sliding plate 206 is used to be pushed by the extrusion end 403 in the state where the knob 401 is subjected to a rotational force, so as to apply a pressure to the elastic member 208.

[0202] The second sliding plate 207 is parallel to the first sliding plate 206. The second sliding plate 207 is arranged on the rolling slide bar 203. Both ends of the second sliding plate 207 are respectively connected to the first support 201 and the second support 202. The second sliding plate 207 is used to move towards the direction close to the bottom plate 100 under the state that the elastic member 208 is applied with pressure, and further drives the roller 300 to move towards the flexible screen of the electronic device.

[0203] In some embodiments, the sliding bracket 200 provided by the embodiment of the present application further includes a first connecting slide rail 212 and a second connecting slide rail 213. The first connecting slide rail 212 is connected to the first support 201, the second connecting slide rail 213 is connected to the second support 202, and both ends of the first sliding plate 206 are connected to the first connecting slide rail 212 and the second connecting slide rail 213 through a first connecting block 214.

[0204] Both ends of the second sliding plate 207 are connected to the first connecting slide rail 212 and the second connecting slide rail 213 through a second connecting block 215.

[0205] When the first sliding plate 206 is driven to move, the first sliding plate 206 can slide on the first connecting slide rail 212 and the second connecting slide rail 213 through the first connecting block 214. Similarly, when the second sliding plate 207 is driven to move, the second sliding plate 207 can slide on the first connecting slide rail 212 and the second connecting slide rail 213 through the second connecting block 215.

[0206] In an example, when the knob 401 is subjected to a forward rotational force, the knob 401 moves downward, the extrusion end 403 pushes the first sliding plate 206 to slide along the first connecting slide rail 212 and the second connecting slide rail 213, and compresses at least one elastic member 208. When at least one elastic member 208 is compressed, it will push the second sliding plate 207 located below it. The rolling slide bar 203 and the roller 300 are driven by the second sliding plate 207 to move towards the bottom plate 100, so as to reduce the distance between the roller 300 and the flexible screen of the electronic device. Until the roller 300 contacts the flexible screen of the electronic device, the adjustment of the distance of the roller 300 in the third direction is completed.

[0207] Next, Figure 16 the structure of an elastic member will be further described.

[0208] Figure 16 FIG. is a schematic structural diagram of an elastic member provided by the embodiment of the present application.

[0209] As Figure 16 shown, in one implementation, the elastic member 208 is a spring.

[0210] At least one elastic member 208 includes two first springs 2081 and two second springs 2082. The two first springs 2081 are symmetrically arranged with respect to the screw rod 402, and the two second springs 2082 are symmetrically arranged with respect to the screw rod 402. The first spring 2081 is located between the second spring 2082 and the screw rod 402. In other words, along the second direction, the second spring 2082, the first spring 2081, the screw rod 402, the first spring 2081, and the second spring 2082 are arranged in sequence. Among them, the outer diameter T1 of the second spring 2082 is greater than the outer diameter T2 of the first spring 2081.

[0211] In one example, when the knob 401 is in a state of receiving a forward acting force, when the acting force is transmitted between the first sliding plate 206 and the second sliding plate 207, the first spring 2081 and the second spring 2082 generate elastic deformations. The first sliding plate 206 pushes the second sliding plate 207 through the first spring 2081 and the second spring 2082, and the second sliding plate 207 drives the roller 300 to move in the third direction to reduce the distance between the roller 300 and the flexible screen of the electronic device.

[0212] In another example, when the knob 401 is in a state of receiving a reverse acting force, the thrust force pushing the second sliding plate 207 disappears, the first spring 2081 and the second spring 2082 recover their elastic deformations, and the second sliding plate 207 drives the roller 300 to move away from the bottom plate 100 in the third direction.

[0213] Among the four elastic members 208, the outer diameter of the first spring 2081 located inside is smaller than that of the second spring 2082. The second springs 2082 located on both sides have a larger outer diameter. During the force application process, the overall stability of the entire sliding bracket 200 can be ensured, avoiding instability of the sliding bracket 200 caused by the inability of both sides of the first sliding plate 206 and the second sliding plate 207 to withstand extrusion. It also effectively reduces the manufacturing cost and is beneficial to reducing the production cost of the entire flexible screen rolling device of the electronic device.

[0214] In other implementation manners, the number of springs is not limited to four. The number of springs can be six or eight, or even more. Or, in other implementation manners, the elastic member 208 can be a component with an elastic function other than a spring.

[0215] The following combines Figure 14 and Figure 17 The display process of the pressure value during the process of the roller 300 pressing on the flexible screen of the electronic device is further introduced.

[0216] Figure 17 It is a schematic structural diagram of an indicating scale and a pressure scale provided by an embodiment of the present application.

[0217] Combined with Figure 14 andFigure 17 As shown, the flexible screen rolling device for electronic devices provided by the embodiments of the present application further includes an indicating scale 209 and a pressure scale 210.

[0218] The indicating scale 209 is arranged on the first sliding plate 206 and can be moved by the first sliding plate 206. An arrow is provided on the indicating scale 209.

[0219] The pressure scale 210 is arranged on the second sliding plate 207 and can be moved by the second sliding plate 207. Pressure values are provided on the pressure scale 210, and the arrow on the indicating scale 209 points to the pressure values.

[0220] In the state where the roller 300 contacts the flexible screen of the electronic device and the knob 401 is continuously rotated, since the roller 300 has been adhered to the flexible screen and there is no elastic connection between the roller 300 and the second sliding plate 207, in this state, the second sliding plate 207 and the pressure scale 210 remain stationary. And between the second sliding plate 207 and the first sliding plate 206, due to at least one elastic member 208 being provided, they are elastically connected. In this state, the first sliding plate 206 can continue to move the indicating scale 209 in the direction towards the second sliding plate 207. At this time, the distance between the first sliding plate 206 and the second sliding plate 207 gradually decreases, the degree of compression of at least one elastic member 208 gradually increases, and the pressure applied to the flexible screen through the roller 300 also gradually increases. The real-time pressure can be presented by the reverse dislocation between the indicating scale 209 and the pressure scale 210 pointed to, realizing stepless pressure adjustment. Among them, the range of the pressure values on the pressure scale 210 can be 0 - 80N.

[0221] In one example, when the rolling pressure of the flexible screen is 20N, by rotating the knob 401 and observing the indicating scale 209 and the pressure scale 210 in real time, when the arrow on the indicating scale 209 points to 20N on the pressure scale 210, stop rotating the knob 401. Optionally, when the roller 300 contacts the flexible screen, the arrow on the indicating scale 209 points to the pressure value "0" on the pressure scale 210. Continuing to rotate the knob 401, the acting force is transmitted to the roller 300, and pressure is generated on the surface of the flexible screen between the rollers 300. The indicating scale 209 continuously moves downward, and the pressure value on the pressure scale 210 pointed to by the arrow on it gradually increases until the value reaches the required pressure "20N", and then stop rotating the knob 401.

[0222] The flexible screen rolling device for electronic devices provided by the embodiments of the present application can not only drive the roller 300 to move along the x, y, and z axes, but also adjust the pressure between the roller 300 and the flexible screen, so as to better meet the rolling requirements and improve the user experience.

[0223] Combined with Figure 3 and Figure 14 As shown, the sliding bracket 200 further includes a housing 211, and the housing 211 covers the outside of the mounting plate 205, the first sliding plate 206 and the second sliding plate 207. By providing the housing 211, it plays a protective role for the mounting plate 205, the first sliding plate 206 and the second sliding plate 207.

[0224] The height of the bottom edge of the housing 211 is higher than the height of the upper edge of the third scale 2032. In other words, the bottom of the housing 211 does not cause any obstruction to the third scale 2032. In this way, on the premise that the housing 211 protects the internal structure, the third scale 2032 can still be used normally without affecting the visualization of determining the moving distance of the roller 300 along the second direction.

[0225] In some embodiments, the housing 211 includes a viewing window 2111, and the viewing window 2111 corresponds to the positions of the indicating scale 209 and the pressure scale 210. In this way, when the rotary knob 401 is rotated, the numerical value of the pressure exerted by the roller 300 on the flexible screen can be observed in real time through the viewing window 2111, which is beneficial to better complete the rolling operation.

[0226] In one implementation, the main frame structure of the electronic device flexible screen rolling device can all adopt rigid materials. For example, the housing 211, the first support 201, the second support 202, and the bottom plate 100 can adopt rigid materials.

[0227] In some feasible implementations, the bottom plate 100 further includes a clamping member, and the clamping member is used to clamp the electronic device to be rolled. So that during the rolling process, the electronic device and the bottom plate 100 remain in a relatively static state.

[0228] In some embodiments, the clamping member can be a clip, a plug or other forms of components, or the clamping member can also be a groove structure. The present application does not specifically limit the structure of the clamping member, as long as the installation stability of the electronic device is satisfied.

[0229] The following will be combined with Figure 3 and Figure 18 to further illustrate the positioning clip.

[0230] Figure 18 is a schematic structural diagram of a positioning clip provided by an embodiment of the present application.

[0231] In one implementation, combined with Figure 5 and Figure 18 , the clamping member can be set in the form of a cross rib 107.

[0232] Optionally, the clamping member can be two vertical and intersecting cross ridges 107, and the center of the clamping member coincides with the center of the first scale 103, the second scale 104 and the third scale 2032. In this way, positioning can be facilitated. At this time, the clamping member can be used to install the electronic device through the corresponding positioning clamp 50. The positioning clamp 50 can be an installation component with a cross groove 50a, and the cross groove 50a of the positioning clamp 50 can be adapted to the ridge 107 of the clamping member. During the installation process, the electronic device can be first fixed on the positioning clamp 50, and then the positioning clamp 50 with the electronic device installed can be installed on the cross ridge 107 of the base plate 100 through the cross groove 50a at the bottom.

[0233] The positioning method adopts the idea of plane x, y coordinate system. The clamping part and the positioning clamp 50 are aligned through the x, y origin to ensure that the relative positions of different products and the clamping part are consistent. At the same time, it is only necessary to align the cross groove 50a of the positioning clamp 50 with the cross ridge 107 of the clamping part to ensure the alignment of the origin, x direction and y direction. The operation is convenient and quick.

[0234] In one implementation, see Figure 14 The base plate 100 provided in the embodiment of the present application is further provided with a foot pad 108, which is disposed on a side away from the first scale 103 and the second scale 104. In other words, the foot pad 108 is disposed on the bottom surface of the base plate 100. The foot pad 108 enables the entire rolling device to be placed more stably on the table, providing a stable foundation for subsequent rolling operations.

[0235] Optionally, the number of the foot pads 108 may be four, and the four foot pads 108 are respectively disposed on the four corners of the base plate 100 .

[0236] It should be noted that those skilled in the art will readily conceive of other embodiments of the present application after considering the specification and practicing the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered merely as exemplary, and the true scope of this application is indicated by the claims.

[0237] It should be understood that the present application is not limited to the exact structures described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present application is limited only by the appended claims.
