Referring to FIG. 1 to FIG. 3 , an embodiment of the present disclosure provides a sliding rail mechanism for a retractable screen structure, including: a bracket assembly 10 and a sliding rail assembly 20 . The bracket assembly 10 includes a bracket 11, and the bracket 11 is provided with a plurality of guide rails 24, and the guide rails 24 are extended along a first direction X (vertical direction shown in FIG. 3 ). The slide rail assembly 20 includes a sliding member 22 and an elastic assembly 230 for connecting the flexible display screen 90 of the retractable screen structure. The elastic assembly 230 includes at least one first elastic member 231 and at least one second elastic member 232, the first end 2311 of the first elastic member 231 is connected to the bracket 11, and the first end 2311 of the first elastic member 231 The two ends 2312 are connected to the sliding member 22 , and the second elastic member 232 is sheathed on at least one of the guide rails 24 .

The number of the second elastic members 232 corresponds to the number of the guide rails 24 , and each guide rail 24 is sleeved with one second elastic member 232 . In this embodiment, there are six sets of guide rails 24, which are symmetrically arranged on the bracket 11, so that the sliding member 22 is more stable when sliding. In other examples, the number of guide rails 24 may also be other, which is not limited in the present disclosure.

In some possible implementations, the slide rail assembly 20 further includes at least one limit stopper 25, which is arranged on the end of the bracket 11 away from the bracket 11 (the upper end in FIG. 3 ), the sliding The member 22 is provided with a limiting portion 221 abutting against the limiting block 25 . The limit block 25 abuts and fits with the limit portion 221 of the slider 22 to limit the initial position of the slider 22 and prevent the slider 22 from detaching from the guide rail 24 . In this embodiment, the limiting portion 221 can be understood as a groove, and there are two limiting blocks 25, which are symmetrically arranged on the bracket 11. The corresponding settings are not limited in the present disclosure. In the example shown in Fig. 3, limit stopper 25 is located at the upper end of support 11, and the initial position of slide member 22 is positioned at the upper end of support 11, and elastic component 230 is in the pre-tensioned state under this state, to slide member 22 An elastic pretension is applied, so that the slide 22 is held in this starting position.

In some possible implementations, the guide rod 240 is sheathed with a plastic part 224 , and the sliding groove 220 is sheathed on the plastic part 224 . The plastic part 224 can reduce the friction between the h chute 220 and the guide rail 24, reduce wear and ensure smooth sliding. In this embodiment, the plastic part 224 can be made of POM (Polyoxymethylene) plastic, which is a self-lubricating plastic. The chute 220 of the slider 22 and the plastic part 224 can be combined together as one part through a co-molding injection molding process (insert-molding), to ensure that the slider 22 can only slide along the extension direction of the guide rail 24, that is, the first direction X, to prevent Sliders come off for increased structural stability.

In some possible implementations, the first elastic member 231 includes an arc-shaped main body portion 233 , a first connecting portion 234 connected to one end of the arc-shaped main body portion 233 , and a first connecting portion 234 connected to the other end of the arc-shaped main body portion 233 . The first connecting portion 234 is connected to the bracket 11 , and the second connecting portion 235 is connected to the sliding member 22 . When the sliding part 22 slides along the guide rail 24, it drives the second connecting part 235 to move so that the first elastic part 231 is deformed, thereby generating a reverse elastic force on the sliding part 22 and the flexible display screen, so that The flexible display stays flat when unfolded. Optionally, the first elastic member 231 and the second elastic member 232 may be metal springs such as springs and extension springs, which have pre-tension force during assembly and can keep the sliding member 22 at the initial position. When the sliding member 22 slides relative to the bracket 11 along the guide rail 24, it drives the second connecting portion 235 of the first elastic member 231 and the second elastic member 232 to move, so that the first elastic member 231 and the second elastic member The elastic member 232 is deformed to generate a reverse elastic force on the sliding member 22 . In this embodiment, the arc-shaped main body portion 233 is C-shaped, and it can be understood that the first elastic member 231 may be a C-shaped spring. There are two first elastic members 231 , which are symmetrically arranged between the bracket 11 and the sliding member 22 . The number of the second elastic member 232 is multiple, part of the second elastic member 232 is arranged between the two first elastic members 231, and another part of the second elastic member 232 is arranged between the two first elastic members 231. the outer side of the first elastic member 231 . The overall elastic force of the elastic component 230 can be increased through the mixed use and spaced arrangement of the two kinds of elastic members, so as to provide greater elastic force for the flexible display screen, so that the flexible display screen can have a longer unfolding stroke. The elastic force can also be kept basically constant, and the tension on the flexible display screen is relatively stable.

The bracket 11 may be provided with a guide groove along the first direction X for assembling the guide rail 24 . When assembling, the second connecting portion 235 of the first elastic member 231 and the sliding member 22 are first riveted together. Then the guide rod 240 of the guide rail 24 is inserted along the guide groove on the lower side of the support 11, and then the chute 220 of the slider 22 and the second elastic member 232 are passed on the guide rod 240 of the guide rail 24, and the guide rod 240 is fully assembled. After inserting the bracket 11, the tail end of the guide rod 240 is fixed firmly with the bracket 11 by spot welding. Finally, the first connecting portion 234 of the first elastic member 231 is fixed on the bracket 11 by riveting, and the assembly of the slide rail assembly 20 and the bracket 11 is completed.

In some possible implementations, the bracket 11 can be made of stamped metal plate, or hollowed out and weight-reduced according to the spatial layout of the whole machine. It is convenient to adjust the space for positions that have a relatively large impact on the strength, and the space utilization rate is better. It can achieve the light and thin effect of the whole machine. The flexible display screen 90 is fixed on the sliding member 22 of the sliding rail assembly 20 . The sliding part 22 can be processed by SUS stainless steel plate and POM plastic plastic co-molding injection molding process. The stainless steel plate can be used as the main body to play the role of strength support, and the chute can be formed by POM plastic injection molding, and can slide with the guide rail 24 to reduce friction. The limit block 25 can be made of plastic material, which can limit the initial position of the slider 22 and prevent the slider 22 from breaking away from the guide rail 24 . The guide rail 24 can be formed by stainless steel stamping process, and fixed on the bracket 11 by spot welding. Cooperate with the chute 220 on the slider 22 to form an undercut structure to prevent the slider 22 from moving away from the guide rail 24 when sliding. The exposed surface of the slider 22 can be used as an adhesive area 226 to be glued and fixed to the flexible display screen 90 . The guide rod 240 may be a cylindrical rod made of metal.

Referring again to FIG. 1 , an embodiment of the present disclosure provides a retractable screen structure, including the slide rail mechanism and the flexible display screen 90 as described in the above embodiments. A shaft assembly 12 is provided on a side of the bracket 11 away from the slide rail assembly 20 , and the axial direction of the shaft assembly 12 is perpendicular to the first direction X. As shown in FIG. A first end of the flexible display screen 90 is connected to the slider 22 , and a second end of the flexible display screen 90 is wound around the shaft assembly 12 .

Through the above arrangement, the sliding member 22 moves relative to the bracket 11 along the first direction X, and can drive the flexible display screen 90 to move together, so as to realize the expansion and retraction of the flexible display screen 90 . The sliding part 22 drives the elastic component 230 to move together, stretches the elastic component 230, and can generate a pre-tension force on the flexible display screen 90, so that the flexible display screen 90 is more flat when unfolded, preventing the whole machine from sliding open visually. Problems such as bulging, bulging and twisting.

In some possible implementations, the shaft assembly 12 includes a shaft support 121 , a shaft 122 and a wheel 123 . The rotating shaft support 121 is disposed on a side of the bracket 11 away from the slide rail assembly 20 . The rotating shaft 122 passes through the rotating shaft support 121 . The rotating wheel 123 is sleeved on the rotating shaft 122 , and the second end of the flexible display screen 90 is wound on the rotating wheel 123 . When the flexible display screen 90 moves together with the sliding member 22, the rotating wheel 123 is passively rotated, so that the flexible display screen 90 can be unfolded and retracted more smoothly.

There may be a plurality of rotating shaft supports 121 arranged at intervals along the second direction perpendicular to the first direction X. The number of runners 123 can be multiple, and a runner is assembled between two adjacent rotating shaft supports 121. According to the size between two adjacent rotating shaft supports 121, the runners can be divided into large rotating wheels and small rotating wheels. Wheels, assembled in proper position.

Referring to FIG. 6 to FIG. 8 , an embodiment of the present disclosure provides an electronic device, which may be a mobile phone, a mobile terminal, a tablet computer, a notebook computer, a terminal handheld device with a screen, a vehicle-mounted display device, and the like. The electronic device includes a casing, the retractable screen structure as described in the above embodiments, and a driving assembly 990 .

The housing includes a first housing 91 and a second housing 92 slidably disposed on the first housing 91 along the first direction X, the first housing 91 is enclosed by the second housing 92 A receiving structure 991 with an opening is formed. The retractable screen structure is disposed in the housing structure 991, the shaft assembly 12 is located on one side close to the second housing 92, and the first end 901 of the flexible display screen 90 is located on a side close to the bottom of the housing. On the side, the second end 902 of the flexible display screen 90 is connected to the first housing 91 to cover the opening. The driving assembly 990 is disposed in the receiving structure 991 and connected to the first housing 91 , the driving assembly 990 is connected to the sliding rail mechanism, and is used to drive the bracket 11 to move along the first direction X. Optionally, the first housing 91 may be provided with a support plate 93 , the second end of the flexible display screen 90 is connected to the support plate 93 , and the support plate 93 may support and protect the flexible display screen 90 . In this embodiment, the driving assembly 990 is connected to the bracket 11 of the slide rail mechanism.

The driving assembly 990 drives the sliding rail mechanism to move along the first direction X, driving the second housing 92, the sliding rail assembly 20, the first end of the flexible display screen 90 and the sliding The member 22 moves relative to the first casing 91 along the first direction X, so that the flexible display screen 90 is switched between a retracted state and an unfolded state.

As shown in Figure 6, due to the pre-tightening of the two elastic components of the elastic component 230, the slider 22 is subjected to the pre-tightening force of the elastic component 230 at the initial position, and due to the existence of the limit stopper 25, it remains in a static state. At the initial position, the flexible display screen 90 is in a withdrawn state.

The driving assembly 990 is fixed on the middle frame (that is, the casing) of the whole machine as a power source, and after the electronic device receives an instruction through the UI, it controls the driving assembly 990 to drive the sliding rail mechanism to move along the first direction X (shown in FIG. 7 as move to the left), so that the slide rail mechanism as a whole slides out relative to the first housing 91 along the direction of the first housing 91 . During this process, the first end of the flexible display screen 90 slides together with the slider 22, and the rotating wheel of the rotating shaft assembly is passively rotated by the force of the flexible display screen 90. connection, so as the slide rail mechanism gradually slides out, the effect that the flexible display screen 90 is gradually unfolded can be realized, as shown in FIG. 7 . During the sliding process of the slide rail mechanism, the sliding member 22 can move from one end of the bracket 11 to the other end under the pull of the flexible display screen, which can further lengthen the unfolded length of the flexible display screen 90 . Moreover, during the sliding process, the elastic component 230 is stretched by the slider 22 to generate an elastic pulling force opposite to the sliding direction on the sliding member 22, and the flexible display screen 90 is always subjected to the pulling force in the opposite direction, which is equivalent to turning the flexible display screen 90 to the right. Pulling makes the stretched flexible display screen 90 more flat, ensures that the curved trajectory of the flexible display screen 90 moves according to the design intention, and prevents problems such as screen bulging, bulging and twisting caused by the sliding of the whole machine visually.

It can be understood that during the whole process, the sliding member 22 is pulled by the second end of the flexible display screen 90 and can move from one end of the bracket 11 to the other end. Assuming that the sliding distance of the slide rail mechanism relative to the first housing 91 is S, and the sliding stroke of the slider 22 is S, then the first end of the flexible display screen 90 moves a distance of 2S relative to the first housing 91 along with the slide rail mechanism. .

When the whole machine receives an external command to retract. The driving motor 130 starts to reversely drive, retracting the sliding rail mechanism and the flexible display screen. During this process, the bracket and the fixing seat are driven by the driving component 990 to move in reverse, the flexible display screen and the sliding part are gradually retracted under the elastic force of the elastic component 230, and the sliding part is under the elastic force of the elastic component 230. Return to the starting position, thereby returning the flexible display to the retracted state. Therefore, adopting the slide rail mechanism of the present disclosure can smoothly and effectively ensure that the flexible display screen maintains the curved shape of the appearance during the sliding and retracting process of the whole machine, and ensures the power generated by the friction force generated during the sliding and retracting process of the screen. The loss is at a low level, with operability and easy-to-implement solutions to ensure product reliability.

Referring to FIG. 6 and FIG. 7 , in some possible implementations, the bracket 11 is provided with a transmission member 13 . The driving assembly 990 includes a driving motor 130, a screw 14 connected to the driving motor 130, and a nut 15 sleeved on the screw 14, the screw 14 extends along the first direction X, and the nut 15 abuts against the transmission member 13 . The driving motor 130 drives the screw 14 to rotate, and drives the nut 15 and the transmission member 13 to move along the first direction X, thereby driving the sliding rail mechanism to move along the first direction X. It should be noted that, the drive assembly 990 may also adopt structures such as rack and pinion, worm gear and the like.

It can be understood that no matter during the unfolding process or the retracting process of the flexible display screen 90 , the elastic component 230 always provides elastic force towards the first casing 91 for the slider 22 and the first end 901 of the flexible display screen 90 . During the unfolding process, the driving force of the driving mechanism drives the slider 22, the first end 901 of the flexible display 90, the bracket 11, and the second casing 92 to move away from the first casing 91 together, and the flexible display 90 is always in contact with the bracket. 11 and the shaft assembly 12 fit together. However, during the retraction process, the driving force of the driving mechanism can only drive the bracket 11 to move towards the first housing 91, and the driving force cannot be transmitted to the slider 22 and the first end 901 of the flexible display screen 90, and the flexible display screen 90 is retracted. The whole process relies on the elastic force provided by the elastic component 230 to pull the slider 22 and the first end 901 of the flexible display 90 back to the initial position.

During this process, there is friction between the flexible display 90 and the exterior decoration, bracket 11 and shaft assembly 12 and there may be additional friction. The sudden change of these frictions will hinder the elastic force of the elastic component 230 The flexible display screen 90 is pulled back, thereby delaying the retraction speed of the flexible display screen 90, resulting in an instantaneous retraction speed of the flexible display screen 90 inconsistent with the retraction speed of the bracket 11, and the retraction speed of the flexible display screen 90 is slower than the retraction speed of the bracket 11, If there is a problem that the retraction of the screen is not synchronized with the retraction of the whole machine, there will be phenomena such as screen swelling and swelling.

Referring to FIG. 9 , in some optional implementations, in order to reduce the occurrence of the above situation, the electronic device of the present disclosure may further include a sensor assembly 80, which is arranged on the bracket 11 for detecting the flexibility The first displacement S1 of the side of the display screen 90 close to the opening (which can be understood as the upper side) relative to the bracket 11 and the side of the flexible display screen 90 away from the opening (which can be understood as the lower side) ) relative to the second displacement S2 of the bracket 11.

When the bracket 11 moves relative to the first casing 91 along the first direction X, it drives the second casing 92, the slider 22, the first end of the flexible display 90 and the first end of the flexible display 90. The second end of the elastic component 230 moves together. According to the difference between the first displacement S1 and the second displacement S2, the support 11 adjusts the speed of moving relative to the first casing 91 .

Through the above arrangement, the sensor assembly 80 detects the first displacement S1 of the side of the flexible display 90 close to the opening relative to the support 11 and the second displacement S2 of the side of the flexible display 90 away from the opening relative to the support 11 When the bracket 11 moves relative to the first casing 91 to expand the flexible display screen 90 , the elastic component 230 can provide the bracket 11 with an elastic force toward the first casing 91 . When the flexible display screen 90 is retracted, the bracket 11 adjusts the speed of moving relative to the first housing 91 according to the difference between the first displacement S1 and the second displacement S2, and the elastic component 230 drives the flexible display screen 90 to retract through the elastic force. The speeds are kept synchronous, so that the flexible display screen 90 is more flat when retracted, preventing problems such as screen bulging, bulging and twisting caused visually. It should be noted that the sensor assembly 80 monitors the retraction of the flexible display screen, and it can be judged according to preset logic rules whether the moving speed of the bracket 11 should be slowed down, that is, the speed of the drive motor 130 is reduced to reduce the retraction of the whole machine. The speed solves the problem that the retraction of the screen is not synchronized with the retraction of the whole machine.

In some possible implementation manners, the electronic device includes an unfolded state (as shown in FIG. 7 ) and a retracted state (as shown in FIG. 6 ). When the electronic device is switched from the retracted state to the unfolded state, the driving assembly 990 of the driving mechanism drives the bracket 11 to move away from the first housing 91 , and the elastic assembly 230 controls the sliding The member 22 provides an elastic force directed toward the first housing 91 .

When the electronic device is switched from the unfolded state to the retracted state, the bracket 11 moves toward the first housing 91 , and the slider 22 moves toward the first housing 91 driven by the elastic force. The direction of the first casing 91 is moved. The bracket 11 adjusts the speed of moving relative to the first housing 91 according to the difference between the first displacement S1 and the second displacement S2, so that the first displacement S1 is not greater than the The second displacement S2. Optionally, during the process of adjusting the speed of the support 11, when the difference between the first position S1 and the second displacement S2 is between 0.05 mm and 0.1 mm, it can be understood that the two sides of the flexible display 90 are opposite to the support. 11 move synchronously, support 11 can stop speed regulation and keep current speed and continue to move.

Wherein, when the electronic device is switched from the expanded state to the retracted state, if the first displacement S1 is less than or equal to the second displacement S2, the bracket 11 remains relative to the first housing 91 moving speed. If the first displacement S1 is greater than the second displacement S2, the support 11 reduces the speed of moving relative to the first casing 91 . It should be noted that when the first displacement S1 is less than or equal to the second displacement S2, it can be understood that both sides of the flexible display 90 move synchronously relative to the support 11 , and there is no need to adjust the moving speed of the support 11 at this time. When the first displacement S1 is greater than the second displacement S2, it can be understood that the two sides of the flexible display 90 do not move synchronously with respect to the support 11, and the retraction speed of the flexible display 90 is lower than the retraction speed of the support 11. At this time, the support 11 needs to be lowered. The moving speed is so that the flexible display screen 90 and the bracket 11 are retracted synchronously, so as to avoid the phenomenon of bulging and bulging of the screen.

In some possible implementation manners, the sensor assembly 80 includes a first sensor 81 and a second sensor 82 , the first sensor 81 is located at a side close to the opening, and is used for detecting the first displacement S1 . The second sensor 82 is located on a side away from the opening, and is used to detect the second displacement S2. Optionally, the first sensor 81 and the second sensor 82 may use optical displacement sensors. In the example shown in the figure, the first sensor 81 and the second sensor 82 are distributed on both sides of the shaft assembly 12, that is, the displacement flexible display screen 90 is arranged around the upper and lower sides of the U-shaped bending area of the shaft assembly 12. sides.

In some possible implementation manners, the electronic device may further include a controller electrically connected to the driving mechanism for controlling the driving mechanism, and the controller is also electrically connected to the sensor assembly 80 . The controller may be the CPU of the electronic device, and adjust the driving speed of the driving mechanism for driving the bracket 11 to move according to the difference between the first displacement S1 and the second displacement S2, so as to change The speed at which the bracket 11 moves relative to the first housing 91 is such that the moving speeds of the flexible display screen 90 and the bracket 11 are balanced, and the two can be withdrawn synchronously. It can be understood that, according to the difference between the first displacement S1 and the second displacement S2, the controller adjusts the driving speed of the driving mechanism for driving the bracket 11 to move, which may refer to the controller According to the difference between the first displacement S1 and the second displacement S2, adjust the rotation speed of the drive motor 130 to control the rotation of the screw 14, so as to change the speed at which the nut 15 moves relative to the screw , so as to change the driving speed of the driving mechanism for driving the bracket 11 to move.
