DETAILED DESCRIPTION

[0045] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0048] An air pressure regulating assembly, the air pressure regulating assembly is used to adjust the pressure of the first damping airbag 11 and the second damping airbag 13, so as to adjust the damping size of the first rotating shaft 5 and the second rotating shaft 7; the air pressure regulating assembly comprises: four air pressure regulating shells 14, two air pressure regulating shells 14 arrays are fixedly connected to the side wall of the second rotating seat 8, and the ends of the two air pressure regulating shells 14 extend close to the side wall of the display screen 9, wherein the ends of the two air pressure regulating shells 14 are fixedly connected to the first annular mounting shell 10, and the ends of the other two air pressure regulating shells 14 are fixedly connected to the second annular mounting shell 12;

[0049] Two hoses 15, ends of the two hoses 15 are fixedly connected to the first annular mounting shell 10 and the second annular mounting shell 12 respectively;

[0050] A piston block 16, the piston block 16 is slidably connected in the air pressure regulating housing 14, and a first spring 17 is fixedly connected between the piston block 16 and the air pressure regulating housing 14;

[0051] A pushing assembly, which is used to push the piston block 16 to move so as to adjust the position of the piston block 16; the pushing assembly comprises: a driving plate 18, a driving groove 1801 is provided on the side wall of the driving plate 18, and the driving groove 1801 comprises a straight groove and an oblique groove; a button 19, the button 19 is slidably connected to the end of the air pressure regulating shell 14, a third spring 20 is fixedly connected between the button 19 and the air pressure regulating shell 14, a driving frame 21 is fixedly connected to the bottom end of the button 19, and the driving frame 21 is slidably connected in the driving groove 1801;

[0052] Specifically, in the prior art, in the process of adjusting the angle of the display screen 9, in order to maintain the angle state of the display, a damper is set at the hinge to increase the resistance at the hinge. However, when manually adjusting the display screen 9, it is also necessary to overcome the resistance of the damper, which makes it more laborious to adjust the display screen 9, thereby increasing the difficulty of adjusting the angle of the display screen 9. The present technical solution can solve the above problem, and the specific operation is as follows:

[0053] When the display screen 9 needs to be adjusted, first press the buttons 19 on both sides of the back of the display with both hands, so that the buttons 19 move along the air pressure regulating shell 14. During the movement, the driving frame 21 moves along the driving groove 1801. The driving frame 21 first moves along the straight groove and then enters the inclined groove. Under the drive of the inclined groove, the driving plate 18 drives the piston block 16 to move toward the side of the display screen 9. The first spring 17 is pulled to reduce the pressure in the air pressure regulating shell 14. Under the connection of the hose 15, the first damping airbag 11 and the second damping airbag 13 are contracted to reduce the contact force with the first friction sleeve 501 and the second friction sleeve 701, thereby reducing friction. On the one hand, the wear of the first friction sleeve 501, the second friction sleeve 701, the first damping airbag 11 and the second damping airbag 13 is reduced to extend the service life. On the other hand, the resistance that needs to be overcome during the adjustment of the display screen 9 is reduced, thereby facilitating the adjustment of the angle of the display screen 9.

[0054] After the adjustment is completed, release both hands, and under the elastic action of the first spring 17, the piston block 16 is pulled, and the pressure in the air pressure regulating shell 14 increases, so that the first damping airbag 11 and the second damping airbag 13 expand, and the contact force with the first friction sleeve 501 and the second friction sleeve 701 is restored, which is conducive to limiting the rotation tendency of the hinge, thereby improving the stability of the display screen 9 after the angle adjustment;

[0055] In addition, when the piston block 16 is pulled by the first spring 17 to move and reset, the drive plate 18 moves. Driven by the inclined groove, the drive rod drives the button 19 to move, and the moving drive rod enters the straight groove. Under the limitation of the straight groove, it is beneficial to maintain the position of the piston block 16.

[0056] It should be noted that the inner ring of the first damping airbag 11 is provided with a first friction plate, and the inner ring of the second damping airbag 13 is provided with a second friction plate.

[0057] Furthermore, a first arc-shaped groove 401 is symmetrically opened in the first rotating seat 4, and first sliding pins 601 are symmetrically fixed to both side walls of the rotating block 6, and the first sliding pins 601 are slidably connected in the first arc-shaped groove 401;

[0058] The two side walls of the rotating block 6 are symmetrically provided with second arc grooves 602, and the two side walls of the second rotating seat 8 are symmetrically fixedly connected with second sliding pins 801, and the second sliding pins 801 are slidably connected in the second arc grooves 602; by setting the first arc groove 401 and the second arc groove 602, the flipping angle of the display screen 9 is limited to avoid excessive flipping of the angle, which causes the display screen 9 to collide with the mounting frame 1.

[0059] Furthermore, an electric telescopic rod 2 is fixedly connected inside the mounting frame 1 , and the top end of the telescopic end of the electric telescopic rod 2 is fixedly connected to the support rod 3 ; the height of the display screen 9 can be adjusted by setting the electric telescopic rod 2 .

[0060] As a further embodiment of the present invention, it also includes:

[0061] A connecting pipe 22, the connecting pipe 22 is fixedly connected to the side wall of the air pressure regulating shell 14, a threaded rod 23 is connected to the inner thread of the connecting pipe 22, a compression block 24 is fixedly connected to the end of the threaded rod 23, and the compression block 24 is slidably connected in the connecting pipe 22;

[0062] Specifically, by providing a connecting tube 22 and a threaded rod 23, if the display screen 9 becomes loose after adjustment, one or more threaded rods 23 are rotated so that the threaded rod 23 drives the compression block 24 to extend into the connecting tube 22, thereby increasing the pressure in the air pressure regulating shell 14. Since the piston block 16 is limited by the straight groove at this time, the increased air pressure enters the first damping airbag 11 and the second damping airbag 13 respectively through the hose 15, increasing the contact force between the first damping airbag 11 and the second damping airbag 13 and the first friction sleeve 501 and the second friction sleeve 701, thereby increasing the friction force and then improving the stability of the display screen 9 after the angle is adjusted.

[0063] As a further embodiment of the present invention, it also includes:

[0064] An L-shaped lifting rod, the bottom end of which is fixedly connected to the top end of the support rod 3, and the top end of the L-shaped lifting rod is symmetrically slidably connected to two first sliding seats 28;

[0065] A second sliding seat 29, both sides of the second sliding seat 29 are slidably connected to the two side walls of the first sliding seat 28, and both sides of the second sliding seat 29 are symmetrically fixedly connected to the third rotating shaft 30;

[0066] A third rotating seat 31, the third rotating seat 31 is rotatably connected to the surface of the third rotating shaft 30, and a camera 32 is fixedly connected to a side wall of the third rotating seat 31;

[0067] A U-shaped bracket 33, the U-shaped bracket 33 is fixedly connected to the bottom of the camera 32, the top of the bottom of the U-shaped bracket 33 is rotatably connected to a first roller 34, and the two inner side walls of the U-shaped bracket 33 are rotatably connected to a plurality of second rollers 35 in a symmetrical array;

[0068] The L-shaped lifting rod includes a mounting rod 25, the bottom end of the mounting rod 25 is fixedly connected to the top of the support rod 3, the top of the mounting rod 25 is slidably connected to an L-shaped sliding frame 26, the L-shaped sliding frame 26 and the mounting rod 25 bracket are fixedly connected to a second spring 27, and a first sliding groove is provided at the top of the L-shaped sliding frame 26;

[0069] Specifically, the existing display screen 9 is equipped with a camera 32, but when the display screen 9 is turned over to be a vertical screen, the camera 32 is located on the side wall of the display screen 9, which leads to the problem that the captured picture is not clear. The technical solution can solve the above problem. The specific operation is as follows:

[0070] During the process of rotating and switching the vertical screen, the first roller 34 and the second roller 35 move along the frame of the display screen 9, and the first roller 34 and the second roller 35 are squeezed by the frame of the display screen 9, so that the L-shaped sliding frame 26 moves upward, and the second spring 27 is pulled until the switching is completed. At this time, the camera 32 is still directly above the display screen 9;

[0071] In addition, by providing a U-shaped bracket 33, during the process of adjusting the angle of the display screen 9, the camera 32 will rotate at the same angle as the display screen 9, so that the camera 32 is parallel to the display screen 9, thereby improving the clarity of the photographed image.

[0072] It should be noted that, in the horizontal screen state, the centers of the first rotation axis 5 and the third rotation axis 30 are coaxial, and in the vertical screen state, the centers of the second rotation axis 7 and the third rotation axis 30 are coaxial.

[0073] As a further embodiment of the present invention, a first arc-shaped slide groove 2601 is symmetrically opened at the top of the L-shaped lifting rod, an arc-shaped slide rod 2602 is fixedly connected in the first arc-shaped slide groove 2601, a first slider 2801 is fixedly connected to the side wall of the first sliding seat 28, and the first slider 2801 is slidably connected to the surface of the arc-shaped slide rod 2602;

[0074] A second arc-shaped sliding groove 2802 is formed on the side wall of the first sliding seat 28, and a second sliding block 2901 is fixedly connected to the sliding side wall of the second sliding seat 29, and the second sliding block 2901 is slidably connected in the second arc-shaped sliding groove 2802;

[0075] It should be noted that, in the vertical screen state, the center of the first arc-shaped slide groove 2601 is concentric with the first rotation axis 5;

[0076] In the horizontal screen state, the center of the second arc-shaped slide groove 2802 is concentric with the second rotation axis 7;

[0077] When the frame of the display screen 9 moves, the camera 32 can rotate synchronously with the display screen 9 through the first arc-shaped slide groove 2601 and the second arc-shaped slide groove 2802, and adjust the angle autonomously, so that the camera 32 is parallel to the display screen 9, thereby improving the stability of the picture during the photo shooting process.

[0078] Working principle of the present invention: when the display screen 9 needs to be adjusted, first press the buttons 19 on both sides of the back of the display with both hands, so that the buttons 19 move along the air pressure regulating shell 14. During the movement, the driving frame 21 moves along the driving groove 1801. The driving frame 21 first moves along the straight groove and then enters the inclined groove. Under the drive of the inclined groove, the driving plate 18 drives the piston block 16 to move toward the side of the display screen 9. The first spring 17 is pulled to reduce the pressure in the air pressure regulating shell 14. Under the connection of the hose 15, the first damping airbag 11 and the second damping airbag 13 are contracted to reduce the contact force with the first friction sleeve 501 and the second friction sleeve 701, thereby reducing friction. On the one hand, the wear of the first friction sleeve 501, the second friction sleeve 701, the first damping airbag 11 and the second damping airbag 13 is reduced to extend the service life. On the other hand, the resistance that needs to be overcome during the adjustment of the display screen 9 is reduced, thereby facilitating the adjustment of the angle of the display screen 9.

[0079] After the adjustment is completed, release your hands. Under the elastic action of the first spring 17, the piston block 16 is pulled, and the pressure in the air pressure regulating shell 14 increases, so that the first damping airbag 11 and the second damping airbag 13 expand, and the contact force with the first friction sleeve 501 and the second friction sleeve 701 is restored, which is beneficial to limit the rotation tendency of the hinge, thereby improving the stability of the display screen 9 after the angle adjustment.
