[0050] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0051] As described in the background art, usually, the area of the folded screen is half of that before folding, and the change in the area of the screen is a jump change, resulting in a poor user experience.

[0052] To solve this technical problem, the present utility model provides an extendable scroll screen, which is applied to a flexible screen.

[0053] Specifically, please refer to Figures 1 - 9 , the extendable scroll screen specifically includes:

[0054] Main housing 1, on one side of the main housing 1, an auxiliary housing 2 is slidably assembled, and an accommodation space 11 is jointly formed between the main housing 1 and the auxiliary housing 2;

[0055] Flexible screen 3, which is arranged at the top of the accommodation space 11;

[0056] Synchronous expansion element 4, which is arranged in the accommodation space 11 and is in driving cooperation with the flexible screen 3;

[0057] The synchronous expansion element 4 includes two pulley wheels 41 arranged oppositely and a transmission belt 42 commonly sleeved on the surfaces of the two pulley wheels 41;

[0058] Wherein, an upper connecting member and a lower connecting member are respectively arranged at the top and bottom of the transmission belt 42, and the upper connecting member and the lower connecting member are respectively connected corresponding to the two ends of the flexible screen 3.

[0059] For the extendable scroll screen provided by the present utility model, through the activation of the synchronous expansion element 4, the fixed seat one 430 and the fixed seat two 440 can synchronously form a traction on the display part 31 and the extension part 33, so that the actual usable area of the flexible screen 3 increases with the increase of the relative distance between the main housing 1 and the auxiliary housing 2, meeting the requirement that the change of the area size of the flexible screen 3 is a gradual change during the actual application process, and can be adaptively adjusted according to the actual application of the user, with higher flexibility, so as to improve the user experience;

[0060] Meanwhile, through the telescopic cooperation between the main housing 1 and the auxiliary housing 2, when the flexible screen 3 does not need to be expanded and used, the overall size of the scroll screen can be reset by the sliding of the auxiliary housing 2 inside the main housing 1.

[0061] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0062] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0063] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0064] Please refer to Figures 1 - 9 , an extendable scroll screen, a main housing 1, on one side of the main housing 1, an auxiliary housing 2 is slidably assembled, and a receiving space 11 is jointly formed between the main housing 1 and the auxiliary housing 2; a flexible screen 3, which is arranged at the top of the receiving space 11; a synchronous expansion element 4, which is arranged in the receiving space 11 and is in transmission cooperation with the flexible screen 3;

[0065] The synchronous expansion element 4 includes two pulley wheels 41 arranged oppositely and a transmission belt 42 commonly sleeved on the surfaces of the two pulley wheels 41. Wherein, an upper connecting member and a lower connecting member are respectively arranged at the top and bottom of the transmission belt 42, and the upper connecting member and the lower connecting member are respectively connected corresponding to the two ends of the flexible screen 3. As Figure 3 shown, the two pulley wheels 41 are respectively arranged on both sides inside the receiving space 11;

[0066] The flexible screen 3 includes a display portion 31, a bending portion 32, and an extension portion 33. The display portion 31, the bending portion 32, and the extension portion 33 are sequentially connected end to end to jointly form the flexible screen 3;

[0067] The upper connecting member is a first fixing base 430, and the lower connecting member is a second fixing base 440. There are three first fixing bases 430. The tops of two adjacent first fixing bases 430 are jointly fixed with a transmission plate 431 connected and fixed to the bottom wall of the display portion 31. The other first fixing base 430 is directly fixed to the bottom of the display portion 31. There are two second fixing bases 440, and both second fixing bases 440 are fixed to the top of the extension portion 33;

[0068] A support guiding platform 13 is fixed to the bottom wall of the main housing 1. The display portion 31 is located between the support guiding platform 13 and the second fixing base 440. Through the action of the above-mentioned transmission plate 431, it can not only form a traction on the display portion 31 when driving along with the transmission belt 42 to smoothly adjust the display area of the flexible screen 3, but also form a supporting effect on the display portion 31 to ensure the overall support stability of the display portion 31;

[0069] The surface of the pulley 41 is movably assembled with a connecting seat 410 fixed to the main housing 1 through a bearing. A servo motor 412 is fixed to the outside of one of the connecting seats 410. The output end of the servo motor 412 penetrates through the connecting seat 410 and is coaxially fixedly assembled with the corresponding pulley 41. In this embodiment, the servo motor 412 is connected to an external power supply module through a power supply wire. It should be noted that the power supply wire should be arranged to avoid the transmission part during the connection arrangement;

[0070] A frame 432 extends from one side of the transmission plate 431. The edge of one side of the display portion 31 is attached to the inner side of the frame 432, and the outside of the frame 432 is fixed to the side wall of the auxiliary housing 2;

[0071] As Figure 1 When it is necessary to adjust the display area of the flexible screen 3 as shown, the servo motor 412 is started to drive the corresponding pulley 41 on it to rotate through its output end. Since the transmission belt 42 is commonly sleeved on the two pulleys 41, when a single pulley 41 rotates, it will drive the other pulley 41 to rotate through the action of the transmission belt 42;

[0072] As Figure 5As shown, when the pulley 41 rotates clockwise, the clockwise rotating drive belt 42 will pull the display part 31 thereon through the first fixing seat 430 connected thereto in a way that it faces the right side. At the same time, when the transmission plate 431 on the first fixing seat 430 is driven, the secondary housing 2 connected thereto will be deployed synchronously. The drive belt 42 will also drive the extension part 33 thereon through the second fixing seat 440 to slide towards the left, so as to satisfy the sliding extension of the overall flexible screen 3. Through the continuous increase of the relative distance between the secondary housing 2 and the main housing 1, the display area of the display part 31 will also increase synchronously, and form a state of extension as shown in Figure 2 shown, which can be adjusted adaptively according to the actual application of the user, with higher flexibility;

[0073] Similarly, when the extended scroll screen needs to be reset, the servo motor 412 drives the pulley 41 to rotate counterclockwise, so that the drive belt 42 drives the flexible screen 3 to slide and reset through the first fixing seat 430 and the second fixing seat 440 thereon, and the secondary housing 2 will also slide and be received towards the direction of the main housing 1, finally completing the receiving and reset function to meet the adjustment and use in different situations.

[0074] The extendable scroll screen provided in Embodiment 1 is further optimized. Specifically, as shown in Figure 3 、 Figure 6 and Figure 8 shown, there are two guiding rollers 12 provided inside the main housing 1. Both of the two guiding rollers 12 are rotatably connected to the corresponding side wall of the main housing 1 through shaft seats;

[0075] The bending part 32 on the flexible screen 3 wraps around the surface of the guiding roller 12. Through the assembly of the guiding roller 12, the display part 31 is located at the top of the accommodating space 11, and the extension part 33 is located at the bottom of the accommodating space 11, and the display part 31 and the extension part 33 are arranged parallel to each other;

[0076] Through the setting of the guiding roller 12, during the process of the synchronous expansion element 4 pulling the display part 31 to increase the display area, the extension part 33 can be guided so that it can extend more smoothly outside the main housing 1. At the same time, through the setting of the guiding roller 12, the connection part between the display part 31 and the extension part 33 can be supported, avoiding excessive bending at the connection part and accelerating the damage of the flexible screen 3, which is beneficial to the better protection and use of the flexible screen 3.

[0077] The extendable scroll screen provided in Embodiment 1 or 2 is further optimized. As shown in Figure 9 shown, the surface of the pulley 41 is provided with tooth grooves 411, and the inner side of the drive belt 42 is provided with tooth blocks 420 adapted to the tooth grooves 411. The drive belt 42 is engaged with the tooth grooves 411 on the corresponding pulley 41 through the tooth blocks 420;

[0078] In Embodiment 1, when the servo motor 412 starts to drive the transmission belt 42 to rotate to extend the display area of the display unit 31, the transmission belt 42 will engage with the tooth grooves 411 on the corresponding pulley 41 through the tooth blocks 420 thereon, which not only ensures the stable transmission of the transmission belt 42, but also avoids the relative slipping between the transmission belt 42 and the pulley 41, making the extension of the flexible screen 3 smoother.

[0079] The usage process of the extendable scroll screen provided by the present utility model is as follows: when it is necessary to increase the effective display area of the display unit 31, start the servo motor 412 so that its output end drives the corresponding pulley 41 and transmission belt 42 thereon to rotate. When the pulley 41 rotates clockwise, the clockwise rotating transmission belt 42 will drive the display unit 31 thereon to be pulled towards the right through the fixing base 430 connected thereto. At the same time, when the transmission plate 431 on the fixing base 430 is in transmission, the secondary housing 2 connected thereto will be unfolded synchronously, so as to meet the sliding extension of the entire flexible screen 3.

[0080] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection or communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0081] Obviously, the above-described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. The preferred embodiments of the present utility model are given in the drawings, but do not limit the patent scope of the present utility model.
