[〇〇〇4] A dual-screen electronic device comprising: a housing having an electronic paper screen mounted on a surface thereof, a cavity formed in the housing, the cavity including an opening formed at one end of the housing; a liquid crystal display module, the liquid crystal display module is slidably mounted in the cavity, comprising a liquid crystal display screen; a first magnet mounted on the liquid crystal display module; and respectively mounted on the housing a second magnet and an electromagnet; wherein when the electromagnet is not energized, the second magnet attracts the first magnet, so that the liquid crystal display module is closed relative to the housing, and the liquid crystal display screen is located in the housing When the electromagnet is energized, the electromagnet attracts the first magnet, so that the liquid crystal display module is opened relative to the housing, and the liquid crystal display screen protrudes from the opening outside the housing. [0005] The present invention satisfies the requirements of the user to view text, pictures, and videos by respectively setting the electronic paper screen and the liquid crystal screen, respectively, to satisfy the 0992014180-0 099107906 form number Α0101, page 3/total 14 pages. [0007] [0009] [Advantages] The placement of a liquid crystal screen in a housing, which is ejected from the housing when needed, avoids damage to the appearance of the electronic device. [Embodiment] «Monthly Referring to Figs. 1, 2, and 3, a dual screen electronic device according to a preferred embodiment of the present invention is disclosed. The electronic device includes a casing 丨〇, an electronic paper screen 2 安装 mounted on an outer surface of the casing 10, a touch module 30 mounted on the electronic paper screen 2 液晶, and a liquid crystal display mounted in the casing 1 〇 Module 4〇. The body 10 has a substantially rectangular shape including a shell 1 .1 and a lower casing 12 , and the electronic paper screen 20 and the touch module 30 are mounted on the upper casing. Referring to FIG. 5, a cavity 13 is formed between the upper and lower housings 11, 12, and the cavity 13 is for accommodating the liquid crystal display module 40. The cavity 13 is formed at the end of the housing 1: The opening 14 through which the liquid crystal display module 4 extends from the housing 1 is formed. Referring to Fig. 3, the upper casing 11 includes a bottom wall 15 and side walls 16 extending perpendicularly from opposite edges of the bottom wall 15, and the side walls 16 are formed with ridges 17 formed. Further, a plurality of fixing posts 18' are formed on the bottom wall 15 close to the surface of the liquid crystal display module 4, and the magnet 51 and the electromagnet 52 are mounted. Wherein, the fixing columns 18 are distributed in a direction perpendicular to the direction in which the ribs 17 extend, and the magnets 51 are mounted on the upper casing 11 at an end away from the opening 14; the electromagnets 52 are mounted on the upper casing 11 at one end near the opening 14. Referring to FIG. 2, FIG. 3 and FIG. 5, the liquid crystal display module 40 includes a frame 41 and a liquid crystal screen 42 mounted on the frame 41. The liquid crystal screen 42 is mounted on the frame 41 near the opening 14. One end of the frame 41 near the opening 14 is a raised end 44. A sliding groove 43 is formed on both sides of the frame 41. The frame 41 is formed with a plurality of receiving grooves 45 away from the opening 14. The extending direction of the receiving groove 45 and sliding 099107906 Form No. A0101 Page 4 / Total 14 pages 0992014180-0 201133178 [ [0011] [0013] The extending direction of the grooves 43 is parallel. A fixing post 46 is formed at one end of the accommodating groove 45. A magnet 53 is also mounted on the frame 41. The chute 43 cooperates with the ridges 17 on the upper casing 11 so that the liquid crystal display module 4 slidable relative to the upper casing 11 in the direction in which the ribs 17 extend. The raised end 44 is used to block the opening 14 when the liquid crystal display module 40 is closed relative to the housing 10. The fixing post 18 of the upper casing 11 extends into the receiving groove 45, and the elastic member 6 is located in the receiving groove 45, and its two ends are respectively fixed to the fixing posts 18, 46. Referring to FIG. 1, FIG. 3 and FIG. 5, when the user uses the electronic farm to perform text reading, it is not necessary to use the liquid crystal screen 42. At this time, the electromagnet 52 is not energized and does not generate magnetism, and the magnet 51 attracts the magnet 53, so that the magnet 51 attracts the magnet 53. The liquid crystal display module 40 is in a closed state with respect to the housing 10, the distance between the fixing posts 18, 46 is at a maximum, and the elastic member 60 is in a fully stretched state. Referring to FIG. 3, FIG. 4 and FIG. 5, when the user wants to view the picture and the video, the user operates the touch module 30 to make the electromagnet 52 charged. At this time, the electromagnet 52 attracts the magnet 53 to make the liquid crystal. The display module 4 is opened relative to the housing 1 so that the liquid crystal screen 42 is exposed, and the user can use the liquid crystal screen 42 to view pictures and videos. At this time, the distance between the fixing posts 18, 46 is the shortest, and the elastic member 60 is in a compressed state. After the user finishes watching the picture and the video, the touch module 3 can be operated to deenergize the electromagnet 52. At this time, the liquid crystal display module returns to the closed state under the action of the magnetic force of the magnet 51 and the elastic force of the elastic member 60. Shape, away,. By separately setting the electronic paper screen 20 and the liquid crystal screen 42 respectively, the present invention satisfies the requirements for the user to view characters, pictures, and videos, and at the same time, the liquid crystal screen 42 is disposed in the casing 10, and is ejected from the casing 1 when needed. , 099107906 Form number Α 0101 Page 5 / Total 14 page 0992014180-0 [0014] 201133178 Avoid damage to the appearance of the electronic device.
