[0032] like Figures 1 to 5 As shown, a scroll screen mobile phone includes a first sliding frame 1, a second sliding frame 2 and a flexible screen 3, the first sliding frame 1 has a plug-in portion 101, the plug-in portion 101 is slidably plugged into the second sliding frame 2, one end of the flexible screen 3 is fixedly connected to the second sliding frame 2, and the lower end of the other end of the flexible screen 3 is fixedly connected to a flexible support plate 14, the flexible screen 3 and the flexible support plate 14 extend into the first sliding frame 1 and are fixedly connected to a rack 4 after being bent downward, the second sliding frame 2 is also fixedly provided with a driving member, the output end of the driving member is fixedly connected with a gear 5 matched with the rack 4, and a supporting structure is also fixedly provided between the flexible screen 3 and the first sliding frame 1; the rack 4 is fixedly connected to the flexible support plate 14; when working, the first sliding frame 1 is slidably connected to the second sliding frame 2, and the plug-in portion 101 is plugged into the second sliding frame 2 to prevent the first sliding frame 1 from being separated from the second sliding frame 2 when the flexible screen 3 is unfolded to the maximum position, and the first sliding frame 1 and the second sliding frame 2 are A cavity is formed between the three of them for installing other components of the mobile phone. When the flexible screen 3 needs to be unfolded or rolled up, the driving member drives the gear 5 to rotate, and the gear 5 cooperates with the rack 4 to move the rack 4 in the cavity. The rack 4 is fixedly connected to the flexible support plate 14, and the flexible support plate 14 is fixedly connected to the flexible screen 3, so the movement of the rack 4 drives the flexible screen 3 to bend downward and roll into the first sliding frame 1. During this process, the flexible support plate 14 is supported by the supporting structure, and the flexible support plate 14 prevents the flexible screen 3 from sliding in contact with the supporting structure and causing damage to the screen. At the same time, the supporting structure enables the flexible support plate 14 and the flexible screen 3 to slide around it. During the unfolding or rolling process of the flexible screen 3, the first sliding frame 1 and the second sliding frame 2 move away from or closer to each other accordingly; the transmission method of gear 5 and rack 4 is adopted here, and its single-stage transmission efficiency can reach 80%, which is significantly improved compared with the transmission method of 70% transmission efficiency of screw rod + screw rod nut, and is a more efficient transmission form for future scroll screen mobile phones.

[0033] The driving component includes a motor 6, the output end of the motor 6 is fixedly connected to a reducer 7, and the gear 5 is fixedly connected to the output end of the reducer 7; a mounting plate 8 is fixedly provided on the second sliding frame 2, and the motor 6 is fixedly mounted on the mounting plate 8; when working, the output shaft of the motor 6 drives the gear 5 to rotate after being decelerated by the reducer 7, and the mounting plate 8 is installed on the second sliding frame 2 so as not to interfere with the movement of the flexible screen 3.

[0034] The flexible support plate 14 is provided with a plurality of through holes 9 ; by providing the through holes 9 on the flexible support plate 14 , the weight of the entire mobile phone can be reduced and heat dissipation of the mobile phone can be facilitated.

[0035] The support structure includes two limit bars 10 symmetrically fixed on the first sliding frame 1, and the two side ends of the flexible support plate 14 are slidably connected to the two limit bars 10; the two limit bars 10 have an arc surface 11 at one end away from the second sliding frame 2, and the flexible support plate 14 is wrapped around the arc surface 11; when working, the flexible support plate 14 slides on the limit bar 10, and the flexible support plate 14 is wrapped around the entire arc surface 11 and bent downward, and the arc surface 11 makes the contact between the limit bar 10 and the flexible support plate 14 smoother.

[0036] The first sliding frame 1 has a housing portion 102, and the flexible screen 3 slides in the housing portion 102 after being bent downward; a limiting surface 12 is provided at the connection between the housing portion 102 and the plug-in portion 101, and the flexible screen 3 can slide as far as the limiting surface 12 after being bent; when working, the flexible screen 3 is bent and slid downward to the limiting surface 12 and stops, and the bent part is stored in the housing portion 102, so that the flexible screen 3 is rolled up.

[0037] A plurality of support rods 13 are fixedly connected between the two limit bars 10; during operation, the middle portion of the flexible screen 3 may collapse if supported only by the limit bars 10, so the support rods 13 are provided to support the middle portion thereof.

[0038] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
