DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, purposes and effects achieved by the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0040] Embodiment I

[0041] As shown in Figs. 1-6, the single-screen expansion screen of the portable notebook computer comprises an external frame 1 and an embedded support;

[0042] The external frame 1 is mounted on the portable notebook computer, and the embedded support is rotatably mounted on the external frame. The embedded support comprises a main body part and a turnover part capable of adjusting the inclination angle of the main body part. The turnover part 2 serves to support the external frame 1 and the portable notebook computer after being turned over.

[0043] The main body part is rotatably mounted on the external frame, and is located at the back of the portable notebook computer. One end of the turnover part 2 capable of adjusting the inclination angle of the main body part is rotatably connected with the main body part.

[0044] In use, the external frame 1 can be rotated relative to the embedded support, and the external frame 1 can be adjusted from a horizontal direction to a vertical direction. The external frame 1 replaces the front and back cover structure of the portable notebook computer, and thus the direction of the external frame 1 is the same as that of the portable notebook computer. Therefore, the direction of the portable notebook computer can also be adjusted, so that the portable notebook computer is not limited to horizontal use, and is more flexible and convenient to use.

[0045] The main body part comprises a mounting disc 3, a rotating block 4 and a connecting seat 5.

[0046] The mounting disc 3 is fixedly mounted on the embedded support 1. The rotating block 4 is rotatably mounted on the mounting disc 3. The connecting seat 5 is mounted on the rotating block 4, and one end of the turnover part 2 is pinned to the connecting seat 5. A limiting assembly is arranged outside the rotating block 4.

[0047] The rotating block 4 can rotate, the design enables the connecting seat 5 to rotate, thereby the direction of the turnover part 2 can be adjusted, and the cooperation of the limiting assembly can limit the position of the rotating block 4, thereby limiting the direction of the turnover part 2.

[0048] The limiting assembly comprises a gear ring 6 and a movable clamping block 7.

[0049] The gear ring 6 is fixedly installed outside the rotating block 4, one end of the movable clamping block 7 is clamped with the gear ring 6, and the other end of the movable clamping block 7 is fixedly installed with a spring 8, and the spring 8 is fixedly connected with the inside of the embedded support 1.

[0050] In use, the turnover part 2 can be rotated by force, the rotating block 4 is driven to rotate by the turnover part 2, the gear ring 6 on the rotating block 4 extrudes the movable clamping block 7, the spring 8 is compressed, and thereby the adjustment of the turnover part 2 is realized, the adjustment mode needs to exert a certain force in use, the pressure exerted by the weight of the notebook computer is smaller than the force when the notebook computer is normally placed, and the turnover part 2 cannot be randomly turned over.

[0051] The outer surface of the movable clamping block 7 is fixedly installed with a pushing block 9, and one end of the pushing block 9 penetrates through a strip-shaped opening on the embedded support 1.

[0052] The design of the pushing block 9 is mainly to facilitate the rotation function of the turnover part 2, in use, the pushing block 9 is pushed downwards, the pushing block 9 drives the movable clamping block 7 to move away from the gear ring 6, at this time, the turnover part 2 can be rotated at will, after the direction of the turnover part 2 is adjusted, the pushing block 9 is released, at this time, the spring 8 restores the deformation, the pushing block 9 is clamped with the gear ring 6, and the limiting can be realized, and the use is more convenient.

[0053] Embodiment two

[0054] As shown in FIGS. 1-6, the embodiment also records the following structure:

[0055] The outer surface of the turnover part 2 connected with the connecting seat 5 is provided with a convex strip 10, a plurality of groups of recesses 11 corresponding to the convex strip 10 are formed on the connecting seat 5, and the plurality of groups of recesses 11 are distributed in a circle at equal intervals with the pin shaft as the center line.

[0056] The turnover part 2 is integrally formed with a reinforcing strip 12 on the end face facing the notebook computer, the strength of the turnover part 2 can be increased, and the turnover part 2 can be prevented from being damaged, and a strip-shaped groove corresponding to the reinforcing strip 12 is formed on the outer frame, and the reinforcing strip 12 is accommodated in the strip-shaped groove.

[0057] The outer frame comprises a front cover and a rear cover, the front cover is arranged on the front end face of the notebook computer, and the rear cover is installed on the rear end of the notebook computer.

[0058] The embedded support is installed on the rear cover, the rear cover is provided with a mounting groove, and the turnover part 2 is located in the inside of the mounting groove when the turnover part 2 is not turned over, and the normal use is not affected.

[0059] As shown in Fig. 1, the front end face of the front cover is provided with a protective steel mesh with an arc-shaped end face near the lower end of both sides, and the protective steel mesh is provided with a sound outlet hole 13 for the horn to propagate sound. The sound outlet hole 13 on the existing single-screen expansion screen is located at the rear, and when the inclination angle is large, the sound is blocked by the desktop, and the use effect is poor.

[0060] The present patent sets the sound outlet hole 13 at the front, and no matter whether the single-screen expansion screen is used horizontally or vertically, there is no interference around when used, and the use effect is better.

[0061] As shown in Fig. 7, the side end face of the single-screen expansion screen is sequentially provided with a plurality of groups of function keys 14 (power key, screen switching key, screen-off key and screen capture key) from top to bottom, Win / ios system switching key 15, screen parameter control rocker 16 and sound size control knob 17. The user can realize "one-key screen projection mode switching" / "one-key screen-off" / "one-key screen capture". The software and circuit technology for realizing these functions are prior art, and therefore, no further description is given.

[0062] The basic principles and main features of the present application and the advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
