[0046] The present application will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, and not to limit the application. In addition, it should be noted that only parts related to the application are shown in the drawings for ease of description.

[0047] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and embodiments.

[0048] Please see Figure 1 The application provides a display assembly, comprising:

[0049] A first housing 100 and a second housing 200, the first housing 100 is provided with a first display panel 110, and the second housing 200 is provided with a second display panel 210;

[0050] A first sliding mechanism 300, comprising a first sliding rail 310 arranged on the first housing 100 and a first rotating shaft 320 arranged on the second housing 200, the first sliding rail 310 and the first rotating shaft 320 are in sliding fit to realize the sliding fit of the first housing 100 and the second housing 200;

[0051] A first hinged mechanism 400 arranged on the second housing 200, the first hinged mechanism 400 is rotatably connected with the first rotating shaft 320 to realize the rotating fit of the first housing 100 and the second housing 200.

[0052] In the application, the first housing 100 and the second housing 200 are defined as sliding in a first direction, the first sliding rail 310 extends in the first direction, the axis of the first rotating shaft 320 extends in a second direction, and the first housing 100 and the second housing 200 can rotate relatively around the axis of the first rotating shaft 320.

[0053] In the embodiment of the application, the first sliding mechanism 300 is arranged to realize the relative sliding between the first housing 100 and the second housing 200, so that the second housing 200 can be pulled out of the first housing 100, and the display module can be switched between the pulled-out state and the storage state. Figures 2-3 As shown in the figure, when the second housing 200 moves towards the first housing 100 and can be completely stored in the internal space of the first housing 100, that is, the storage state of the display module. Figure 1 and Figure 4 As shown in the figure, when the second housing 200 moves away from the first housing 100 and completely pulls out of the internal space of the first housing 100, that is, the pulled-out state of the display module.

[0054] Figures 5A schematic view of angle adjustment when the display module is applied to a notebook display device is shown in FIG. 1. The first hinge mechanism 400 is provided to realize relative rotation between the first housing 100 and the second housing 200, so that the second housing 200 can realize angle adjustment in the pulled-out state. In the embodiment, the rotation angle between the first housing 100 and the second housing 200 is not limited. In the embodiment, the second housing 200 can rotate within the range of 0-90°. It should be noted that in the embodiment, the display module includes two extreme states, i.e., a flat state and a flip state. For example, 0° is the flat state of the display module, i.e., the state in which the first housing 100 and the second housing 200 are parallel or coplanar, and 90° is the flip state in which the two screens of the display module are close to each other, i.e., the extension direction of the first housing 100 and the second housing 200 is perpendicular.

[0055] It can be understood that in the embodiment, the first housing 100 is provided with a frame at the edge position, which can limit the rotation angle of the second housing 200. In some embodiments, the first housing 100 can be provided with a first connecting block 430 avoiding hole, etc., to realize rotation angle adjustment, for example, can rotate within the range of 0-180°, which is not limited in the application.

[0056] The display module provided in the embodiment can realize double-screen display on the display module by using the first sliding mechanism 300 and the first hinge mechanism 400, improve display diversity and display effect, and in application, the second housing 200 can be pulled out of the first housing 100 and rotated within any angle, realize application diversity, reduce the structural complexity of the display module, and improve the assembly convenience and assembly yield of the display module.

[0057] The second housing 200 can be accommodated in the first housing 100. The first display panel 110 is the outer screen of the display module, and the second display panel 210 is the inner screen of the display module, i.e., when the display module is in the accommodation state, the first display panel 110 is on the side facing the user, and when the second display panel 210 is not used, the first display panel 110 can be used for normal display when the display module is in the accommodation state. When double-screen display is needed, the second display panel 210 can be pulled out of the first housing 100 and fixed in position and adjusted in angle by the hinge mechanism, thereby facilitating the use of the second display panel 210.

[0058] The types of the first display panel 110 and the second display panel 210 are not limited in the embodiments of the present application, and the first display panel 110 and the second display panel 210 can be liquid crystal display panels, organic light emitting diode (OLED) display panels, active-matrix organic light emitting diode (AMOLED) display panels, passive-matrix OLED display panels, quantum dot light emitting diode (QLED) display panels, or the like.

[0059] The types of the first display panel 110 and the second display panel 210 can be the same or different. For example, the first display panel 110 can be an LCD liquid crystal display panel, and the second display panel 210 can be an OLED flexible display panel. The second display panel 210 does not need a backlight module, and thus the thickness and weight of the display device can be reduced, and the display device is convenient to carry. In the embodiments of the present application, the second housing 200 can fix the second display panel 210, and the flexible display panel and the second housing 200 are fixed by using a frame sealant, so as to prevent the flexible display panel from being deformed after being pulled out, and to protect the inner screen.

[0060] As shown in FIG. 1, Figures 6-7 In the embodiments of the present application, the first hinge mechanism 400 includes a hinge sleeve 410 sleeved on the first rotating shaft 320 and a sleeve pipe 420 arranged between the first rotating shaft 320 and the hinge sleeve 410. The hinge sleeve 410 is fixed on the second housing 200 through a first connecting block 430, and the sleeve pipe 420 is used to realize the friction fit between the hinge sleeve 410 and the first rotating shaft 320. The display module can be adjusted and fixed by the first hinge mechanism 400, so that the rotatable display device can be used at different opening angles.

[0061] In order to prevent the second housing 200 from sliding to the contracted state during rotation, a first limiting mechanism 500 is arranged on the first housing 100 in the embodiments of the present application, so as to lock the first rotating shaft 320. Specifically, Figure 8 As shown in FIG. 1,

[0062] The first limiting mechanism 500 arranged on the first housing 100 includes a first limiting plate 510 and a first limiting hole 520 arranged on the first limiting plate 510, wherein,

[0063] The first limiting plate 510 is provided with a first guide rail 530 parallel to the first slide rail 310, and one end of the first rotating shaft 320 is slidably connected to the first guide rail 530 through the first slide rail 310.

[0064] The first limiting hole 520 is used to engage with the first rotating shaft 320 when the first rotating shaft 320 slides to the end of the first slide rail 310, so as to limit the relative rotation between the first rotating shaft 320 and the first shell 100.

[0065] It should be noted that the length of the first limiting plate 510 is not limited in the embodiments of the present application. In the embodiments of the present application, the first limiting plate 510 is arranged on one side of the end of the first slide rail 310, and the length of the first limiting plate 510 is less than the length of the first slide rail 310. The sliding of the first rotating shaft 320 is limited and guided by the first slide rail 310. When the first rotating shaft 320 slides to the end of the first slide rail 310, the first rotating shaft 320 is further guided by the first guide rail 530 on the first limiting plate 510, so as to slide to the position of the first limiting hole 520. When the first rotating shaft 320 moves to the position of the first limiting hole 520, the first rotating shaft 320 engages with the first limiting hole 520, so as to limit the rotation of the first rotating shaft 320 relative to the first shell 100. When the second shell 200 rotates around the axis of the first rotating shaft 320, only the hinged sleeve 410 is driven to rotate relative to the first rotating shaft 320, and the first rotating shaft 320 does not rotate relative to the first shell 100.

[0066] When the first limiting mechanism 500 is arranged, as shown in Figures 9-10 The first limiting mechanism 500 further includes a limiting block 550 fixedly connected to the first limiting plate 510, and the first limiting hole 520 is arranged on the limiting block 550. The limiting block 550 is provided with an opening 560 connected to the first guide rail 530, and the end surface of the opening 560 is a slope 570 inclined from the side close to the first guide rail 530 to the center of the first limiting hole 520.

[0067] It can be understood that, in the embodiment of the present application, in order to facilitate processing, the limiting block 550 and the first limiting plate 510 adopt a split structure, the limiting block 550 is in a cylindrical structure, the first limiting plate 510 is provided with a mounting hole 540 for fixing the limiting block 550, and the opening 560 of the limiting block 550 is used for alignment of the first guide rail 530 so that the first rotating shaft 320 can slide from the first guide rail 530 to the position of the limiting hole. By setting the end surface of the opening 560 as a slope 570 structure, that is, in the limiting hole, the opening is in a closed manner, the resistance of the first rotating shaft 320 sliding out of the limiting hole can be increased, and the second shell 200 is prevented from moving towards the first shell 100 during rotation, thereby affecting the rotation performance and the like.

[0068] In the embodiment of the present application, the height of the opening 560 in the direction perpendicular to the first limiting plate 510 gradually decreases, which facilitates sliding of the first rotating shaft 320 in and out while achieving limiting; by adjusting the size of the opening 560, the limiting force of the first rotating shaft 320 can be controlled. In application, the limiting block 550 can be made of elastic material to realize the deformability of the size of the opening 560, thereby improving the use effect of the display module. Of course, in other embodiments, the limiting hole can also be provided on the first limiting plate 510, that is, the first limiting plate 510 and the limiting block 550 are in an integrated structure, and in different embodiments, selection is made according to needs.

[0069] Please continue to refer to Figures 6-7 In the embodiment of the present application, a first rotating shaft 320 cooperating with the first sliding mechanism 300 and the first limiting mechanism 500 is also provided, specifically, the first rotating shaft 320 includes a first shaft body 331 cooperating with the first hinged mechanism 400 and a second shaft body 331 provided at one end of the first shaft body 331, and the cross-sectional shape of the first shaft body 331 is circular.

[0070] The cross-sectional shape of the second shaft body 331 is hexagonal, the second shaft body 331 includes two parallel sliding surfaces, and the sliding surfaces are used for sliding cooperation with the first guide rail 530; the second shaft body 331 is also used for clamping with the first limiting hole 520, and the cross-sectional shape of the first limiting hole 520 is matched with the cross-sectional shape of the second shaft body 331.

[0071] In the present application, the second shaft body 331 with a hexagonal structure is arranged on the first rotating shaft 320, and the second shaft body 331 can meet the sliding performance, and can also guide the process of entering the limiting hole from the first guide rail 530, prevent the slope 570 at the opening 560 position from being stuck, and affect the movement of the second rotating shaft 710, and the like; in addition, the limiting hole also adopts a hexagonal structure, and through the limiting effect of the limiting hole and the second shaft body 331 hexagonal structure, the first shaft body 331 can be prevented from being partially rotated by the hinged sleeve 410 when the second shell 200 rotates relative to the first shell 100, thereby affecting the rotation of the second shell 200.

[0072] The first sliding rail 310 includes a first rail 311 and a second rail 312 arranged on both sides of the hinged sleeve 410, and the first rail 311 and the second rail 312 are respectively in sliding fit with the first shaft body 331; the first sliding mechanism 300 further includes two stoppers 340 sleeved on the first shaft body 331, and the stoppers 340 are respectively in sliding fit with the first rail 311 and the second rail 312; the stopper 340 includes a stop surface 341 in contact with the upper surface of the first sliding rail 310, and the stop surface 341 is used to limit the movement of the second shell 200 in the direction perpendicular to the first sliding rail 310.

[0073] In the present application, the double-rail and stopper 340 mode is adopted to improve the guiding accuracy and sliding accuracy of the first sliding rail 310, prevent the second shell 200 from deviating during sliding, and affect the movement accuracy of the display module; in particular, the upper and lower rails on the first limiting mechanism 500 arranged at the end of the first sliding rail 310 and the rails on the first sliding rail 310 need to maintain high alignment accuracy, prevent the rotation shaft from being limited by the first limiting mechanism 500, prevent the movement in the up-down direction during sliding by the positioning of the outer rail stopper 340, and improve the movement effect of the display module.

[0074] In the present application, in order to thin the thickness of the second shell 200, the first shell 100 is provided with electrical elements such as a battery and a circuit board, and the power supply and communication of the second display panel 210 are realized through the electrical elements on the first shell 100. In the present application, the electrical connection mechanism 900 is arranged at the edge adjacent to the first shell 100 and the second shell 200 to realize the electrical connection of the second display panel 210. Specifically, as shown in Figures 11-13 The display module further includes:

[0075] An electric connection mechanism 900 is arranged on the first housing 100 and the second housing 200, and is used to realize the electric connection of the second display panel 210 when the first rotating shaft 320 slides to the end of the first sliding rail 310, and the first connection end 910 contacts with the second connection end 920.

[0076] A second sliding mechanism 600 is arranged on the first housing 100 and the second connection end 920, and is used to realize the sliding cooperation of the second connection end 920 and the first housing 100.

[0077] The second connection end 920 can move together with the first sliding mechanism 300 through the second sliding mechanism 600, which facilitates the alignment of the first connection end 910 and the second connection end 920, improves the alignment accuracy, and realizes the electric connection. In order to further improve the cooperation stability of the first connection end 910 and the second connection end 920, the first connection end 910 and the second connection end 920 are provided with a plurality of clamping modes, and the two connection terminals are in contact to realize the electric connection after the clamping of the first connection end 910 and the second connection end 920. The clamping mode can also improve the connection strength and stability, prevent the first connection end 910 and the second connection end 920 from being separated during rotation, and affect the use of the display module.

[0078] Optionally, the first connection end 910 is provided with an outer clamping portion 930, the outer clamping portion 930 is provided with an inner clamping portion 950, and the inner clamping portion 950 is provided with a first connection terminal 970; the second connection end 920 is provided with an outer clamping portion 940 matched with the outer clamping portion 930, the outer clamping portion 940 is provided with an inner clamping portion 960 matched with the inner clamping portion 950, and the inner clamping portion 960 is provided with a second connection terminal 980; the second connection terminal 980 is electrically connected with the second display panel 210 through a flexible flat cable 990.

[0079] In order not to affect the connection of the first connection end 910 and the second connection end 920 during the rotation of the second housing 200, a hinge mechanism and a limiting mechanism are arranged at the connection position of the first connection end 910 and the second connection end 920 to realize the rotation and limiting functions. In the embodiment of the application, the display module further comprises:

[0080] A second hinge mechanism 700 is arranged on the second shell 200, and the second hinge mechanism 700 comprises a second connecting block 720 fixedly connected with the second shell 200 and a second rotating shaft 710 rotatably connected with the second connecting end 920.

[0081] A second limiting mechanism 800 is arranged on the first shell 100, and the second limiting mechanism 800 comprises a second limiting plate 810 and a second limiting hole 820 arranged on the second limiting plate 810. The second limiting plate 810 is provided with a second guide rail 830 parallel to the second sliding rail 610, and one end of the second rotating shaft 710 is slidably connected with the second guide rail 830 through the second sliding rail 610. The second limiting hole 820 is used for clamping the second rotating shaft 710 when the second rotating shaft 710 slides to the end of the second sliding rail 610, so as to limit the relative rotation between the second rotating shaft 710 and the second shell 200.

[0082] In the embodiment of the present application, the second hinge mechanism 700 is arranged, so that the second shell 200 can also rotate relative to the second connecting block 720 during the rotation, thereby preventing the second connecting end 920 from being separated from the first connecting end 910, and further affecting the electrical connection performance.
