Description

Technical Field

[0001] This utility model relates to the field of extended screen technology, specifically to a retractable extended screen for laptops. Background Technology

[0002] Laptops, as a convenient and efficient mobile office and entertainment tool, have been widely integrated into people's daily life and work. With the increase in usage demands and the size limitations of laptops, the laptop screens themselves have significant limitations. Therefore, many users use extended screens to obtain additional display areas, improve work efficiency, or enhance the visual experience.

[0003] Currently, most commonly used extended screens are single, independent displays. When multiple screens need to be used collaboratively, multiple extended screens are required, which involves additional wiring. Furthermore, laptops have limited ports, often necessitating the use of a docking station. Independent displays are also inconvenient to store, lacking portability. Therefore, those skilled in the art have provided a retractable extended screen for laptops to address the problems mentioned in the background. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figures 1 to 5 As shown in the figure, a retractable extended screen for a laptop computer in this embodiment includes a base 1, with a support plate 4 fixedly connected to the lower rear end of the base 1; both ends of the base 1 are rotatably connected to damping shafts 6, and the outer ends of the two damping shafts 6 are respectively rotatably connected to a right display screen 2 and a left display screen 3. The right display screen 2 and the left display screen 3 each have two degrees of freedom of rotation in two horizontal planes, thereby realizing folding and unfolding. When folded, the volume is small and easy to carry; when unfolded, it can provide the extension function of two screens, with strong functionality.

[0032] The right display screen 2 and the left display screen 3 have the same structure, both with an L-shaped cross section, and are stacked symmetrically on top of the support plate 4. The right display screen 2 is stacked on top of the left display screen 3, with the back of the right display screen 2 facing upwards and the back of the left display screen 3 also facing upwards, while the screen portion faces downwards. This ensures that the screen portions of both displays can be protected when folded, making it less likely to damage the screens during storage and carrying.

[0033] When unfolding, first unfold the right display screen 2 outward by 180°, then turn it forward. Then unfold the left display screen 3 in the same way to complete the unfolding of both displays. When in use, the laptop can be placed in front of the center of the two displays. At the same time, both the left and right displays can be adjusted in both horizontal and vertical angles. They can be adjusted to the same angle as the laptop screen, or they can be adjusted to different angles to meet different usage needs, making it highly flexible.

[0034] The left display screen 3 includes a back plate 31 and an outer frame 33 that are fixedly connected to each other, and the display screen body 32 is fixedly connected inside the back plate 31 and the outer frame 33.

[0035] In this embodiment, the base 1 is equipped with a motherboard 8 and multiple interfaces 7 electrically connected to the motherboard 8. The ports of the interfaces 7 extend to the outer end of the base 1. The upper end of the base 1 is detachably connected to a top cover 9. The motherboard 8 is electrically connected to two displays. The multiple interfaces 7 enable the two displays to connect to and be powered on by the laptop. The integrated structure design eliminates the need for a docking station, making it more convenient to use.

[0036] The types of interfaces 7 include, but are not limited to, USB-A interfaces, USB-C interfaces, and HDMI interfaces. The top cover 9 is designed for easy maintenance and can be detached using screws or clips.

[0037] Example 2

[0038] Please see Figure 6 As shown, based on Embodiment 1, the damping shaft 6 includes a fixed shaft 61 fixed to the base 1. A connecting collar 62 capable of rotating in a vertical plane is sleeved on the outer end of the fixed shaft 61. The lower end of the connecting collar 62 is annular and sleeved on the outer end of the fixed shaft 61. A nut is sleeved on the outer end of the fixed shaft 61, and a washer is provided on the part that contacts the connecting collar 62. Damping is formed by the compression of the nut. A connecting rod 63 capable of rotating in a horizontal plane is rotatably connected to the upper end of the connecting collar 62. The two connecting rods 63 are fixedly connected to the inner protrusions of the right display screen 2 and the left display screen 3, respectively. Through the setting of the connecting rods 63 and the connecting collar 62, the left and right display screens each have two degrees of freedom of rotation in the horizontal plane, thereby completing the folding or unfolding.

[0039] In addition, for ease of use, the outer end of the connecting collar 62 is detachably connected to a housing 64. Inside the housing 64, there is a button circuit board 65 and a button 66 that contacts the contacts of the button circuit board 65. The button 66 extends out of the housing 64. The button circuit board 65 is electrically connected to the main board 8. The set function is realized by pressing the button 66, including but not limited to turning the display on and off and switching between split screens.

[0040] Example 3

[0041] Please see Figure 1 and 3 As shown, based on Embodiment 1, in order to prevent the two displays from accidentally unfolding after being folded up, latches 5 are rotatably connected to both sides of the rear end of the support plate 4. The latches 5 are L-shaped and their upper ends are engaged with the outer end of the right display 2. The latches 5 can limit the two folded displays, thereby preventing accidental unfolding and improving safety.

[0042] In addition, multiple rubber pads are fixedly connected to the upper and lower ends of the support plate 4. The rubber pads at the bottom can play an anti-slip role and improve the stability of the support plate 4 when it is placed, while the rubber pads at the upper end of the support plate 4 play a cushioning role. Since the left display screen 3 faces downward after it is folded up, the rubber pads can protect the screen and prevent damage.

[0043] The rubber pads at the bottom of the support plate 4 are distributed at the four corners of the support plate 4 and are arranged around the center, while the rubber pads on the upper surface of the support plate 4 are in the shape of a ring and fixed in the middle of the support plate 4.

[0044] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
