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

[0030] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0031] Please see Figures 1-5 This invention provides a technical solution: a force-saving adjustment mechanism for a monitor stand, comprising a stand base 1 and a stand fixing shaft 2 mounted on the top surface of the stand base 1. A first connecting mechanism is mounted on the top surface of the stand fixing shaft 2, and a stand arm 3 is mounted on the outer surface of the first connecting mechanism. The first connecting mechanism is used to movably mount the stand arm 3. A second connecting mechanism is mounted on the other end surface of the stand arm 3, and a monitor fixing mechanism is mounted on the outer surface of the second connecting mechanism. The monitor fixing mechanism is used to fix the monitor, and the second connecting mechanism is used to connect and fix the monitor fixing mechanism.

[0032] Specifically, the first connecting mechanism includes a connecting component one and a force-saving adjustment component. The connecting component one is installed on the top surface of the bracket fixing shaft 2, and the force-saving adjustment component is installed inside the connecting component. A power supply component is installed inside the bracket fixing shaft 2. The connecting component one includes a connecting seat 4 and a first pre-tightening spring 7. The connecting seat 4 is installed on the top surface of the bracket fixing shaft 2. A mounting cavity 5 is opened on one side surface of the connecting seat 4. A mounting support shaft 6 is movably installed on the inner wall of the mounting cavity 5. The two end surfaces of the mounting support shaft 6 extend to the outer surface of the connecting seat 4. The first pre-tightening spring 7 is installed between the outer surface of the mounting support shaft 6 and the inner wall of the mounting cavity 5. The bracket arm 3 is installed on the outer surface of the mounting support shaft 6.

[0033] Furthermore, the effort-saving adjustment component includes a compression spring 9 and a compression plate 10. The compression spring 9 is installed on the end surface of the mounting shaft 6, and the compression plate 10 is installed on the end surface of the compression spring 9. A limit support shaft 11 is installed on the side surface of the compression plate 10 adjacent to the compression spring 9. A magnet 12 is installed on the end surface of the limit support shaft 11, and an electromagnet 13 is installed on the inner wall of the mounting cavity 5. Due to the magnetic attraction between the electromagnet 13 and the magnet 12, the limit support shaft 11 is driven to move into the mounting cavity 5, thereby causing the compression plate 10 to squeeze the compression spring 9, so that the compression spring 9 applies pressure to the mounting shaft 6, thereby adjusting the preload of the mounting shaft 6 according to the weight of the display, so as to ensure the stability of the display installation while ensuring easy adjustment.

[0034] Furthermore, the power supply assembly includes a power supply battery 15 and a sealing cover 16. A battery slot 14 is formed on the outer surface of the bracket fixing shaft 2. The power supply battery 15 is movably installed on the inner wall of the battery slot 14. The sealing cover 16 is movably installed on the inner wall of the battery slot 14 outside the power supply battery 15. A controller 17 is installed on the outer surface of the bracket fixing shaft 2 below the battery slot 14. The power supply battery 15 is electrically connected to the controller 17, and the controller 17 is electrically connected to the electromagnet 13, providing power to the electromagnet 13 through the power supply battery 15.

[0035] Furthermore, the second connecting mechanism includes a second connecting component and a connecting block 20. The second connecting component is installed on the end surface of the support arm 3, and the connecting block 20 is installed on the outer surface of the second connecting component. The second connecting component includes a second pre-tension spring 21 and an adjusting support shaft 19. An adjusting groove 18 is provided on the end surface of the support arm 3. The adjusting support shaft 19 is movably installed on the inner wall of the adjusting groove 18. The connecting block 20 is installed on the outer surface of the adjusting support shaft 19. Both ends of the adjusting support shaft 19 extend to the outer side of the support arm 3. The second pre-tension spring 21 is installed between the outer surface of the support arm 3 and the outer surface of the adjusting support shaft 19. By rotating the display fixing plate 22, the angle of the display is adjusted by rotating the adjusting support shaft 19. The adjusting support shaft 19 is fixed by the second pre-tension spring 21. Then, the position of the display is adjusted by rotating the support arm 3. The support arm 3 is fixed by the first pre-tension spring 7, thus completing the installation and adjustment of the display.

[0036] Furthermore, the display fixing structure includes a display fixing plate 22 and a pressure sensing component. The display fixing plate 22 is mounted on one side surface of the connecting block 20. Several positioning bolts 23 are movably installed inside the display fixing plate 22. The pressure sensing component is mounted on the bottom surface of the display fixing plate 22 and includes a return spring 26 and a pressure sensor 28. A movable elongated groove 24 is formed on the bottom surface of the display fixing plate 22. A pressure support shaft 25 is movably installed on the inner wall of the movable elongated groove 24. The return spring 26 is mounted on the top surface of the pressure support shaft 25. Between the inner wall of the surface and the movable long groove 24, a pressure plate 27 is installed on the bottom surface of the pressure support shaft 25. Several pressure sensors 28 are installed on the top surface of the pressure plate 27. A pad 8 is installed on the top surface of the pressure sensor 28. The pressure sensor 28 is electrically connected to the controller 17. The display to be installed is placed on the display fixing plate 22. The display and the display fixing plate 22 are connected as a whole by the positioning bolts 23. The bottom surface of the display is in contact with the surface of the pad 8. The pressure of the bottom surface of the display on the pad 8 is transmitted to the pressure sensor 28.

[0037] When using (working), if a monitor stand is required, place the monitor to be installed on the monitor mounting plate 22 and connect the monitor to the monitor mounting plate 22 as a whole using the positioning bolts 23. The bottom surface of the monitor is in contact with the surface of the pad 8. The pressure of the bottom surface of the monitor on the pad 8 is transmitted to the pressure sensor 28. The pressure sensor 28 senses the pressure value of the monitor on the pad 8 and then transmits the data to the controller 17. The greater the weight of the monitor, the greater the pressure value. At this time, the controller 17 controls the current flowing through the electromagnet 13 to be greater, so the magnetic attraction between the electromagnet 13 and the magnet block 12 is greater.

[0038] Because there is a magnetic attraction between the electromagnet 13 and the magnet block 12, the limiting support shaft 11 is driven to move into the mounting cavity 5, thereby driving the clamping plate 10 to squeeze the clamping spring 9, so that the clamping spring 9 applies pressure to the mounting support shaft 6, thereby adjusting the preload of the mounting support shaft 6 according to the weight of the display, so as to ensure the stability of the display installation while ensuring easy adjustment.

[0039] According to the usage requirements, rotate the monitor mounting plate 22, adjust the angle of the monitor by rotating the adjustment shaft 19, fix the adjustment shaft 19 by the second pre-tightening spring 21, then adjust the position of the monitor by rotating the bracket arm 3, and fix the bracket arm 3 by the first pre-tightening spring 7 to complete the installation and adjustment of the monitor.
