[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0041] Example 1

[0042] like Figure 1-6 As shown, the portable notebook single-screen extension screen includes an external frame 1 and an embedded bracket;

[0043] The external frame 1 is mounted on the portable notebook; the embedded bracket is rotatably mounted on the external frame; wherein the embedded bracket includes a main body and a flip portion 2 whose tilt angle can be adjusted. After flipping, the flip portion 2 plays the role of supporting the external frame 1 and the portable notebook:

[0044] The main body is rotatably mounted on the external frame, and the main body is located directly behind the portable notebook; one end of the flip part 2 which can adjust the tilt angle of the main body is rotatably connected to the main body.

[0045] When in use, the external frame 1 and the embedded bracket can be rotated, and the external frame 1 can be adjusted from horizontal to vertical. The external frame 1 replaces the front and back cover structure of the portable notebook. Therefore, the external frame 1 has the same direction as the portable notebook, and the direction of the portable notebook can also be adjusted, so that the portable notebook is not limited to being used only horizontally. It is more flexible and convenient to use.

[0046] The main body includes a mounting plate 3, a rotating block 4 and a connecting seat 5:

[0047] The mounting plate 3 is fixedly mounted on the embedded bracket 1; the rotating block 4 is rotatably mounted on the mounting plate 3; the connecting seat 5 is mounted on the rotating block 4, and one end of the flip portion 2 is pin-connected to the connecting seat 5; wherein, a limiting component is provided on the outside of the rotating block 4.

[0048] The rotating block 4 can rotate. This design enables the connecting seat 5 to rotate, thereby adjusting the direction of the flip part 2. Cooperating with the limiting component, the position of the rotating block 4 can be limited, thereby limiting the direction of the flip part 2.

[0049] The limiting assembly includes a gear ring 6 and a movable block 7:

[0050] The ring gear 6 is fixedly mounted on the outside of the rotating block 4; one end of the movable clamping block 7 is engaged with the ring gear 6, and the other end of the movable clamping block 7 is fixedly mounted with a spring 8, which is fixedly connected to the inside of the embedded bracket 1.

[0051] When in use, the flip part 2 can be rotated with force, and the flip part 2 drives the rotating block 4 to rotate. The gear ring 6 on the rotating block 4 squeezes the movable block 7, causing the spring 8 to compress, thereby realizing the adjustment of the flip part 2. This adjustment method requires applying a certain force when in use. When placed normally, the pressure applied by the weight of the portable notebook is less than this force, and the flip part 2 will not flip randomly.

[0052] A shift block 9 is fixedly mounted on the outer surface of the movable clamping block 7 , and one end of the shift block 9 passes through the strip-shaped opening on the embedded bracket 1 .

[0053] The design of the shift block 9 is mainly to facilitate the use of the rotation function of the flip part 2. When in use, push the shift block 9 downward, and the shift block 9 drives the movable clamping block 7 away from the ring gear 6. At this time, the flip part 2 can be rotated arbitrarily. After adjusting the direction of the flip part 2, release the shift block 9. At this time, the spring 8 recovers its deformation, and the shift block 9 is pushed to clamp the ring gear 6 to achieve limiting, which is more convenient to use.

[0054] Example 2

[0055] On the basis of Example 1, Figure 1-6 As shown, this embodiment also records the following structure:

[0056] The outer surface where the flip part 2 is connected to the connecting seat 5 is provided with a ridge 10, and the connecting seat 5 is provided with several groups of grooves 11 corresponding to the ridges 10. The several groups of grooves 11 are equidistantly distributed around the circumference with the pin connecting the flip part 2 and the connecting seat 5 as the center line.

[0057] A reinforcing strip 12 is integrally formed on one end surface of the flip part 2 facing the portable notebook, which can increase the strength of the flip part 2 and prevent the flip part 2 from being damaged. A strip groove corresponding to the reinforcing strip 12 is opened on the external frame for accommodating the reinforcing strip 12.

[0058] The external frame includes a front cover and a back cover. The front cover is arranged on the front end surface of the portable notebook, and the back cover is installed on the back end of the portable notebook.

[0059] The embedded bracket is installed on the back cover, and a mounting groove is provided on the back cover. When the flip part 2 is not flipped, it is located inside the mounting groove and does not affect normal use.

[0060] like Figure 1 As shown, the front end surface of the front cover is provided with a protective steel mesh with an arc-shaped end surface on both sides near the lower end. The protective steel mesh is provided with a sound hole 13 for the speaker to transmit sound. The sound hole 13 on the existing single-screen extended screen is located at the rear. When the tilt angle is large, the sound is blocked by the desktop and the use effect is poor.

[0061] This patent sets the sound hole 13 in the front. No matter whether the single-screen extended screen is used horizontally or vertically, there is no interference from the surroundings during use, and the use effect is better.

[0062] like Figure 7 As shown, the side surface of the single-screen extended screen is provided with several groups of function buttons 14 (power button, screen switch button, screen off button and screenshot button), Win / ios system switch button 15, screen parameter control joystick 16 and speaker size control knob 17 from top to bottom. Users can realize "one-key screen projection mode switching" / "one-key screen off" / "one-key screenshot". The software and circuit technology for realizing these functions are existing technologies and therefore will not be elaborated on.

[0063] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
