Description

Technical Field

[0001] This utility model relates to the field of extended screens, and particularly to a dual-sided extended screen for portable laptops. Background Technology

[0002] Portable laptops refer to personal laptops with high mobility. Generally speaking, laptops 12 inches or smaller and weighing no more than 2 kg can be considered portable laptops. The primary consideration for portable laptops is portability.

[0003] A dual-screen monitor is a type of desktop monitor that typically involves fixing the screens to a stand with screws, allowing for the use of two screens interchangeably.

[0004] The existing patent, CN220894806U, entitled "A Utility Model Patent for a Portable Laptop Extended Dual-Screen Display Device," describes a device comprising a mounting frame, a first connector, a second connector, a display module, and two wing plates. The two wing plates are rotatably connected to the back ends of the mounting frame. The first connector is disposed on the wing plates, and the second connector is disposed on the back of the display module. The first and second connectors are magnetically connected. The two side LCD screen assemblies are magnetically connected to the main structure for communication and fixation. The two side LCD screen assemblies can be placed vertically or horizontally to meet the environmental requirements of both horizontal and vertical display on a laptop. The mounting frame can be pulled left and right to adjust its horizontal dimensions, allowing the dual-screen device to be hung on laptop screens of different sizes.

[0005] The structure described in the aforementioned patent is a common dual-screen display structure on the market. However, in actual use, due to the weight of the dual-screen structure and the frame itself, the screen components of the portable laptop are subjected to significant pressure during prolonged use, making them prone to damage. Furthermore, when the portable laptop is tilted, gravity causes the dual-screen structure to become vertical. Adding a magnetic structure at this point is problematic; ordinary magnetic structures lack sufficient magnetic attraction, while strong magnetic structures interfere with the use of the portable laptop, easily causing damage and shortening its lifespan, thus failing to meet user requirements.

[0006] In summary, existing tablet computer support structures have certain shortcomings. Therefore, we propose a dual-sided extended screen for portable laptops. Utility Model Content

[0043] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0044] Example 1

[0045] like Figure 1-5 As shown, the portable laptop dual-sided extended screen includes a support frame 1, a connecting component, a mounting bracket 2, and an extended screen 3;

[0046] The rear end face of the support frame 1 is provided with an interface component for connecting to a laptop computer, and the rear end of the support frame 1 is provided with limit components 7 near both sides; there are two sets of connecting components, and the connecting components are detachably installed on both sides of the support frame 1 near the rear end.

[0047] Mounting bracket 2 is mounted on the connecting assembly; extended screen 3 is embedded in mounting bracket 2;

[0048] The connecting assembly includes a connecting block 4, a supporting rotating shaft 5, and a 360-degree rotating shaft 6: one end of the supporting rotating shaft 5 is rotatably connected to the connecting block 4, and the other end of the supporting rotating shaft 5 is inserted into the inside of the support frame 1 and limited by the limiting assembly 7; the 360-degree rotating shaft 6 is rotatably mounted on the connecting block 4, and the upper end of the 360-degree rotating shaft 6 extends into the inside of the mounting frame 2 and is fixedly connected to the mounting frame 2.

[0049] The 360-degree rotating shaft 6 enables the mounting bracket 2 to rotate 360 ​​degrees perpendicular to the desktop. During use, it can be adjusted to other directions for easy viewing by people in the surrounding area, resulting in a good user experience.

[0050] The interface components include a Type-C interface and a USB interface for connecting to the two sets of extended screens 3. By connecting to a computer, the two sets of extended screens 3 can be displayed, and the two extended screens 3 can be lit, connected and controlled simultaneously.

[0051] The rear end of the mounting bracket 2 is also equipped with several sets of function keys, which can realize "one-click screen mirroring", "one-click mute", "one-click screenshot" and "one-click screen off" of the extended screen 3, helping users to use the extended screen 3 more conveniently and protect their privacy. The overall functionality is quite strong. The above are technologies commonly used in existing mobile phones. This patent has not improved them, so they will not be described in detail.

[0052] In use, the connecting block 4 is rotated around the supporting rotating shaft 5, and then the mounting bracket 2 is rotated around the 360-degree rotating shaft 6 to change the tilt angle of the mounting bracket 2, thereby adjusting the angle of the extended screen 3 so that relevant personnel can easily view it.

[0053] When stored, its structure is similar to that of a laptop, with the extended screen 3 located on the inside, which protects the screen so it is not easily damaged and has a relatively long service life.

[0054] This utility model describes a portable double-sided extended screen for laptops. It changes the existing hanging structure and adopts a support and double rotation structure, so that the double-sided extended screen can be folded together when not in use. The volume of the double-sided extended screen is only slightly larger than that of a single extended screen 3, making it very convenient to carry. Moreover, it does not put pressure on the laptop screen hinge during use and does not affect the operation of the laptop. It has good performance and good application prospects.

[0055] Example 2

[0056] like Figure 1-9 As shown, based on Embodiment 1, this embodiment also includes the following structure:

[0057] The outer surface of the supporting rotating shaft 5 is provided with several sets of slots 51 at equal intervals, and the limiting component 7 engages with any one of the slots 51.

[0058] When in use, the distance between the two sets of extended screens 3 is different when the limiting component 7 is engaged with the slot 51 at different positions, so that it can be used with laptops of different sizes.

[0059] The limiting component 7 includes a movable part 71, a locking block 72, and a fixing part 73.

[0060] The movable part 71 is located inside the support frame 1, and a locking block 72 that is inserted into the locking slot 51 is installed on the movable part 71; the fixing part 73 is located inside the support frame 1 and is used to limit the position of the movable part 71.

[0061] When the distance between the extended screens 3 is not adjusted, the card block 72 is always inserted inside the card slot 51, limiting the position of the support rotation axis 5 and preventing the support rotation axis 5 from rotating.

[0062] The movable part 71 is equipped with a press-type latch 74, and the fixed part 73 is equipped with a latch 75 for locking the position of the press-type latch 74.

[0063] The push-button block 74 and the locking element 75 are existing and commonly used locking structures, so their specific shapes will not be described in detail.

[0064] When adjusting the distance between the extended screens 3, the press-type latch 74 and the latch 75 are locked in place. At this time, the support rotation shaft 5 can be pulled directly to change the position of the support rotation shaft 5, thereby fixing the position of the extended screen 3.

[0065] The movable part 71 is equipped with a button and a reset component:

[0066] One end of the button passes through a hole on the support frame 1 and extends to the outside of the support frame 1; one end of the reset component is mounted on the movable part 71, and the other end of the reset component is mounted inside the support frame 1.

[0067] When adjusting the distance between the extended screens 3, press the button. The button drives the movable part 71 to move, thereby causing the press-type latch 74 on the movable part 71 to engage with the latch 72. When the position of the support rotation shaft 5 is adjusted, press the button again. The press-type latch 74 and the latch 72 separate, the reset spring 76 restores its deformation, and pushes the movable part 71 to move, so that the latch 72 is inserted into the slot 51, thereby achieving the limit of the support rotation shaft 5.

[0068] The reset component uses a reset spring 76. There are two sets of reset springs 76, and the two ends of the reset spring 76 are fixedly connected to the inner wall of the movable part 71 and the support frame 1, respectively.

[0069] The reset component can also be implemented using other elastic structures, such as a spring, or an elastic rope at the other end of the movable part 71.

[0070] A connecting shaft 41 is installed on the connecting block 4. The lower end of the 360-degree rotating shaft 6 is rotatably connected to the connecting shaft 41. The 360-degree rotating shaft 6 is inserted into the lower end face of the mounting bracket 2 near the end position. The 360-degree rotating shaft 6 and the mounting bracket 2 are connected by bolts.

[0071] Both the 360-degree rotating shaft 6 and the supporting rotating shaft 5 limit the rotation angle through damping.

[0072] Support feet 8 are installed on the lower end face of the support frame 1 near both sides to adjust the tilt angle of the support frame 1, which can adjust the tilt angle of the support frame 1 to make it easier for people to use the laptop.

[0073] Figure 1 In order to show the structure of the support leg 8, the entire structure is flipped up for display, with the actual support leg 8 located at the bottom.

[0074] This utility model describes a portable laptop double-sided extended screen, which includes a connecting component. The supporting rotating shaft 5 cooperates with the limiting component 7 to change the distance between the two extended screens 3, making the extended screen 3 suitable for laptops of different widths. It has high overall applicability. The connecting block 4 can rotate relative to the supporting rotating shaft 5, and the mounting bracket 2 can rotate around the 360-degree rotating shaft 6, thus allowing the extended screen 3 to be presented at a wide angle, meeting the needs of different users, with good performance and promising application prospects.

[0075] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
