DETAILED DESCRIPTION

[0051] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0052] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0053] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0054] Example 1

[0055] Reference Figure 1 , Attachment Figure 2 , Attachment Figure 3 And attached Figure 4 The display device provided in the embodiment of the present application includes a main body 1, a shell 2 and at least one display screen 3; the main body 1 has at least one accommodating cavity; the at least one display screen 3 is movably arranged in the at least one accommodating cavity and can be stored in or extended out of the corresponding accommodating cavity; the shell 2 is arranged on at least one surface of the main body, and the shell 2 can have different structural forms relative to the main body 1, so that the display screen 3 has different relative positional relationships with the target bearing surface; wherein the target bearing surface is the surface of the platform supporting the display device.

[0056] Specifically, in order to solve the problem that a portable display has only one display screen, cannot be stored and is easily damaged by bumps, the display device provided in this embodiment arranges at least one display screen 3 in the main body 1, and extends or retracts the shell 2 in different structural forms, so that the screen can be stored, thereby avoiding the problem of screen damage caused by bumps.

[0057] Among them, the main body 1 is a rigid structure, which can be a plate with a certain thickness, a frame structure, a box body, etc., as long as it can provide an accommodation space for at least one display screen; accordingly, a sliding part can be set on the main body 1 to cooperate with the extension and storage of the display screen, which can be but not limited to a slide groove, a slide rail, a pulley, etc.; the shape and size of the main body 1 are not limited here, and can be designed and adjusted according to actual needs.

[0058] Among them, the type of display screen 3 is not limited, and it can be an LED display screen, an OLED display screen, a mini-OLED display screen, a touch screen, etc., or in other embodiments it can also be a touchpad or an electronic writing board; the number of display screens 3 can be designed and adjusted according to actual needs, for example, two display screens 3 can be pulled out back to back, pulled out at a certain angle, and pulled out in the same direction; the same applies to three, which will not be elaborated here. Of course, corresponding to the different numbers of display screens 3, the number of accommodating cavities can also be designed and adjusted accordingly, for example: the display screen 3 and the accommodating cavity correspond one to one, and for example: a plurality of display screens can be accommodated in one accommodating cavity at the same time. In this embodiment, the display screen 3 is pulled out relative to the accommodating cavity for storage and extension, and the display screen 3 will not be deformed or the angle changes. For example: if Figure 2 and Figure 3 As shown, one or two display screens are extracted to cooperate with the display screen of the electronic device 4 for extended display or split-screen display, providing a larger and more complete display screen in scenarios such as table statistics, data sorting, curve analysis, and presentations; as shown Figure 2 As shown, a display screen can be pulled out and used as a drawing board, and cooperate with the display screen of an electronic device for display; for another example, two display screens are stacked in the same direction, one can be a display screen, and the other can be a handwriting board or touch pad, and one of them can be pulled out and used according to actual needs. The pull-out setting of the display screen 3 can be matched with the different forms of the housing 2 to meet the needs of special usage scenarios, that is, it can be used as a supplementary screen with other display devices or laptops.

[0059] Among them, the shell 2 can be a rigid structure or a flexible structure. The shell 2 can be a one-piece structure that is fixedly connected to the body 1 and cannot be detached, for example: the edge or part of the surface of the shell 2 is fixedly connected to the edge or part of the surface of the body 1; the shell 2 can also be a split structure that is detachable from the body 1, for example: it is detachably connected by magnetic attraction. In this setting form, the shell 2 can be a plate structure surrounding the body 1, or it can be an additional structure wrapped outside the body 1; the shell 2 can be set separately corresponding to the front / back / side of the body 1, and the shell 2 can also be set simultaneously corresponding to the front and back of the body 1; in this embodiment, the shell 2 can be deformed to form different structural forms. When the shell 2 is deformed into different structural forms, it can make the display screen 3 have different relative positions relative to the target bearing surface, for example: parallel to the target bearing surface, inclined at an angle to the target bearing surface, the extended surface of the display screen 2 intersecting with the target bearing surface, etc., and then when it cooperates with other display devices or laptops, it can be applicable to the position and layout requirements of various different scenes. It can be understood that the target bearing surface can be but not limited to a desktop, a placement platform surface, the ground, etc.

[0060] According to the above, the display device provided by the present application, by arranging at least one push-pull display screen 3 in the main body 1, enables at least one display screen 3 to be extended separately when used with an electronic device to adapt to different multi-screen usage scenario requirements; thereby solving the problem that the portable display has only one display screen and cannot meet the requirements of special usage scenarios.

[0061] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B, which is specifically understood as: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may exist.

[0062] Further, see Attachment Figure 2 and attached Figure 5 In the display device provided in this embodiment, in a specific implementation, the body 1 includes a first plate body; the at least one accommodating cavity is arranged on the first surface 11 and / or the second surface of the first plate body, the first surface 11 and the second surface are two surfaces of the first plate body arranged opposite to each other in a first direction a, and the first direction a is perpendicular to the thickness direction of the first plate body; and / or the shell 2 includes a first shell 21 arranged on a first side of the first plate body and / or a second shell 22 arranged on a second side of the first plate body, the first side and the second side are two opposite sides of the first plate body in the thickness direction.

[0063] Specifically, when the body 1 is a plate structure, the opening of the accommodating cavity can be opened on the first surface 11 and / or the second surface of the plate body. One opening or multiple openings can be opened on the first surface 11 or the second surface corresponding to the number of display screens. Of course, one opening can also correspond to multiple display screens 3, or openings can be opened on the first surface 11 and the second surface at the same time. The number of openings can be designed and adjusted according to the display screens 3 and actual design needs. The shell 2 includes a first shell 21 and / or a second shell 22, so as to correspond to the above-mentioned shell 2 can be set separately to the front / back of the body 1, and the shell 2 can also be set to the front and back of the body 1 at the same time; when the first shell 21 and the second shell 22 are set at the same time, the two can be a split structure or a mutually connected structure, for example: connected at a position corresponding to the third side of the body 1, and the connection method can be rotation, flexibility, bonding, etc. The third side of the body 1 is a side that is adjacent to the first side and the second side at the same time. When the first shell 21 or the second shell 22 is set separately, the first shell 21 or the second shell 22 can be deformed to achieve a change in structural form. The deformation of the first shell 21 can adjust the use state of the electronic device 4, and the deformation of the second shell 22 can not only adjust the use state of the electronic device 4 but also adjust the display state of the display screen 3 relative to the target bearing surface; when the first shell 21 and the second shell 22 are set at the same time, at least one of them can be deformed to achieve a change in structural form.

[0064] Further, see Attachment Figure 8 , Attachment Fig. 9 and attached Fig.10 In the display device provided in this embodiment, in a specific implementation, the first shell 21 includes at least two first sub-shells 211 that can rotate relative to each other, and the at least two first sub-shells 211 form a first supporting structure with different structural forms on the first side through relative rotation with each other, so as to support the electronic device 4 so that the electronic device 4 and the display device have a first relative position relationship; and / or, the second shell 22 includes a second sub-shell 221 and a third sub-shell 222 that are rotatably connected, and the second sub-shell 221 can rotate relative to the third sub-shell 222, so that it is away from the first edge of the third sub-shell 222 and away from or close to the second side of the first plate body.

[0065] Specifically, in order to realize the deformability of the shell 2, in this embodiment, the first shell 21 is configured to include at least two first sub-shells 211, and the second shell 22 is configured to include a second sub-shell 221 and a third sub-shell 222. Of course, it can be understood that the first shell 21 and the second shell 22 exist separately or simultaneously without affecting their respective structural settings; at least two first sub-shells 211 can be selected and rotated by a rotating shaft, a flexible connection, a magnetic connection, etc., and then when the number of the first sub-shells 211 is two, it can be rotated to form Fig.10 In the state shown, one of the first sub-shells 211 can be flipped in the direction away from the first side of the first plate body to a state at a specified angle with the first body, forming an inclined support surface 212, so that the electronic device 4 can be abutted against the support surface 212 and cooperate with the first plate body to form a corresponding use state. Under this setting mode, the other first sub-shell 211 can be magnetically connected, adhesively connected or fixedly connected to the first plate body to prevent relative movement with the first plate body, thereby ensuring stable support of the support surface 212; refer to the attached Figure 8 In this embodiment, the number of the first sub-shells 211 can also be set to four, wherein the three first sub-shells 211 (fourth sub-shells 231) can be flipped in the direction away from the first side of the first plate body to form a triangular prism structure with a triangular cross-section or a quadrangular prism structure with a rectangular cross-section, not only forming a support surface 212 but also forming a support end 213 at the upper end of the support surface 212, that is, the support surface 212 can be perpendicular to the first plate body or can be inclined relative to the first plate body, and the support end 213 can be formed at the upper end of the support surface 212, so that the electronic device 4 can not only fit on the support surface 212, but also be supported on the support end 213 to form a larger inclination angle, that is, Figure 1 and Figure 2 In this embodiment, the number of the first sub-shells 211 can also be set to three, that is, Fig.10As shown, the two first sub-shells 211 (fourth sub-shell 231) can be turned in the direction away from the first side of the first plate to form a triangular prism. The size of each first sub-shell 211 can be the same or different. For example, when the first shell 21 can be formed into a triangular prism with a triangular cross-section, the cross-section can be an equilateral triangle, an isosceles triangle, an obtuse triangle, etc. It can be understood that the electronic device 4 can be but not limited to a laptop computer, a tablet computer, etc., and when the support end 213 is matched, the ground of the electronic device 4 can be used or the foot pad structure it has to achieve a snap-on connection or a greater frictional resistance. For the second shell 22, the rotational connection method of the second sub-shell 221 and the third sub-shell 222 is the same as the first sub-shell 211, which will not be described here; the third sub-shell 222 can be movably connected to the first plate or fixedly connected. When the end of the second sub-shell 221 away from the third shell 222 is away from the first plate, it can cooperate with the edge of the first plate and the target bearing surface to form a triangular support structure, so that the first plate and the target bearing surface are in an inclined support form with an angle, which can change the position state of the display screen 3 relative to the target bearing surface and the position state of the first plate for the electronic device 4 and even the support state of the first shell 21 for the electronic device 4. Under this setting mode, the fixed setting of the third sub-shell 222 can ensure the stable inclined support of the second sub-shell 221 for the first plate. When there is a connection between the first shell 21 and the second shell 22, it can correspond to the third side of the first plate by means of a rotating shaft, a flexible connection, a magnetic attraction, etc.

[0066] Further, see Attachment Figure 5 The display device provided in this embodiment, in a specific implementation, further includes at least one functional component 5 arranged in the accommodating cavity; a first opening 12 connected to the accommodating cavity is opened on the first side of the first plate body, and when the first shell 21 forms a first supporting structure, at least one functional component 5 can be exposed through the first opening 12; and / or, a second opening connected to the accommodating cavity is opened on the second side of the first plate body, and when the second shell 22 has a first structural form, at least one functional component 5 can be exposed through the second opening.

[0067] Specifically, in order to realize the display work of the display screen 3, at least one functional component 5 is set in this embodiment. The functional component 5 can be a mainboard, and can also include a battery, a heat dissipation component, etc. In this embodiment, the functional component 5 is always set in the accommodating cavity and electrically connected to the display screen 3 to realize data interaction. Of course, data interaction can also be performed with other display screens or electronic devices 4 through the mainboard. Under this setting mode, in this embodiment, the first side and the second side of the first plate body can be set in the form of an opening to form a frame structure, and the first shell 21 and the second shell 22 are used to block the opening, which can not only reduce the weight of the overall device, but also effectively improve the heat dissipation efficiency. When the first shell 21 and the second shell 22 are deformed to form a supporting structure, the shielding of the opening is cancelled, and then the functional component 5 can be exposed through the opening, which improves the heat dissipation efficiency and the convenience of maintenance; the shape and size of the first opening 12 and the second opening are not limited here, and can be designed and adjusted according to actual needs. It can be understood that the first structural form here is the form in which the shell 2 is deformed to form a bracket or a supporting structure.

[0068] Further, see Attachment Figure 6 In the display device provided in this embodiment, in a specific implementation, the accommodating cavity includes a first accommodating cavity 14 and a second accommodating cavity 15 respectively arranged on the first surface 11 and the second surface of the first plate body, and the first accommodating cavity 14 and the second accommodating cavity 15 are respectively used to accommodate the first display screen 31 and the second display screen 32; wherein, the first accommodating cavity 14 and the second accommodating cavity 15 are stacked in the thickness direction of the first plate body; the first accommodating cavity 14 and the second accommodating cavity 15 are connected or not connected; and / or, the projection areas of the first accommodating cavity 14 and the second accommodating cavity 15 in the thickness direction of the first plate body overlap or do not overlap.

[0069] Specifically, in order to realize the pulling and pulling of multiple display screens 3 relative to the accommodating cavity, the first accommodating cavity 14 and the second accommodating cavity 15 are provided in this embodiment to accommodate the first display screen 31 and the second display screen 32 respectively, and openings are provided on the first surface 11 and the second surface of the first plate body to form the pulling and pulling openings of the corresponding display screens; in this embodiment, the first accommodating cavity 14 and the second accommodating cavity 15 are stacked to make the first display screen 31 and the second display screen 32 as large as possible, and the first accommodating cavity 14 and the second accommodating cavity 15 can also be arranged in a relative form at the same height as required, sacrificing part of the display area to reduce the thickness of the overall device. The first accommodating cavity 14 and the second accommodating cavity 15 can be interconnected or not. When interconnected, the heat dissipation efficiency can be improved. When not connected, the independence of the internal display screen can be effectively guaranteed to avoid external impurities, particles, and sharp objects from entering and affecting or even scratching the display screen. The size of the first accommodating cavity 14 and the second accommodating cavity 15 can be the same or different to adapt to display screens 3 of different sizes and realize diversified display states and usage scenarios. Under the above-mentioned setting mode, the functional component 5 can be arranged between the first accommodating cavity 14 and the second accommodating cavity 15 or in the first accommodating cavity 14 or in the second accommodating cavity 15.

[0070] Further, see Attachment Figure 5 and attached Figure 6 In the display device provided in this embodiment, in a specific implementation, the display screen 3 also includes a first structural member 33 protruding from the accommodating cavity in the stored state; when the display screen 33 is in the stored state, the first structural member 33 can be blocked on the first surface 11 and / or the second surface of the first plate body; and / or, when the display screen 3 is in the extended state, the first structural member 33 can provide supporting force to the display screen 3.

[0071] Specifically, in order to improve the convenience of pulling out the display screen 3, a first structural member 33 is provided in the present embodiment. The first structural member 33 is a rigid structure, and can be a plate, a strip, a block, a handle, etc., as long as it can provide a force position for pulling out the display screen 3; at the same time, in the present embodiment, the first structural member 33 can also be used as an appearance member of the overall device, that is, to block the opening of the corresponding accommodation cavity, for example: Figure 5 The first surface 11 of the first plate body is provided with a first opening 12. When the first display screen 31 is received therein, the first structural member 33 can block the first opening 12. The first opening 12 can be blocked only or the first surface 11 can be completely covered. Figure 6As shown, the first surface 11 is ensured to have a smooth appearance, and accordingly, a second structural member 34 can be provided on the second display screen 32. In addition, the first display screen 31 can enter and exit the first accommodating cavity 14 through the first opening 12, so the first accommodating cavity 14 and the first opening 12 must be greater than the thickness of the first display screen 31 in the thickness direction, and then when the first structural member 33 is matched with the first opening 12, the first structural member 33 can cooperate with the target bearing surface to support the first display screen 33 when the first display screen 33 is pulled out so that it remains in a suspended state spaced from the target bearing surface.

[0072] Further, see Attachment Figure 5 The display device provided in this embodiment, in a specific implementation, further includes a speaker assembly 6 arranged in the accommodating cavity, and the third surface 13 of the first plate body is provided with a through hole connected to the accommodating cavity corresponding to the speaker assembly 6; and / or, the third surface 13 of the first plate body and / or the fourth surface of the second shell 22 are also provided with a second structural member (not shown in the figure), and the friction coefficient of the second structural member is greater than that of the first plate body.

[0073] Specifically, in order to improve the diversity of the functions of the display device, a speaker assembly 6 is provided in this embodiment, so that the display device can also be used as an external speaker of the electronic device 4; here, the third surface 13 of the first plate body and the aforementioned third side are two opposite surfaces, and the third surface 13 is the surface not covered by the shell 2, and the speaker assembly 6 is arranged on this surface in conjunction with the through hole, and the speaker assembly 6 is connected to the functional component 5 by signal to realize data interaction.
