[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0032] like Figure 1-5 and Figure 7 As shown, the screen adjustment structure based on human body posture of the present invention comprises a base 1 with a built-in control module, the base 1 is provided with a support 2 which can be moved forwards and backwards, the support 2 is provided with an inclined support arm 5, the upper end of the support arm 5 is fixed with an insert sleeve 6, and the insert sleeve 6 is used to install the plug column of the display screen; the base 1 is provided with an adjusting movable seat 12 and an adjusting movable device for driving the adjusting movable seat 12 to move forwards and backwards, the adjusting movable seat 12 is provided with an adjusting push block 14 which cooperates with the support arm 5, the support 2 is provided with a locking device, the support 2 and the support arm 5 are connected by a rotating device, and the rotating device is provided with a clamping device 20, the insert sleeve 6 is provided with a push rod 7 which can pass through the lower part thereof, and the adjusting movable seat 12 is also provided with an adjusting inclined block 16 which cooperates with the lower end of the push rod 7.

[0033] In some embodiments, the above-mentioned locking device includes an electromagnet block 9 arranged in the base 1 and an iron block 8 in the support 2, and the support 2 is locked by the magnetic attraction force generated by the electromagnet block 9 on the iron block 8. The rotating device includes a mounting seat 3 arranged on the support 2, and a mounting shaft 4 is installed on the mounting seat 3. The support arm 5 is sleeved on the mounting shaft 4, and the support arm 5 is fixedly connected to the mounting shaft 4.

[0034] Preferably, the installation shaft 4 is a hollow steel shaft.

[0035] At the same time, a clamping device 20 capable of limiting the rotation of the mounting shaft 4 is arranged on the mounting seat 3 .

[0036] In some embodiments, the clamping device 20 includes a clamping mounting block 21 arranged on the outside of the mounting seat 3, and the clamping mounting block 21 is connected to an electromagnet column 22 that passes through the mounting seat 3 and is inserted into the mounting shaft 4. The rotation of the mounting shaft 4 is limited by the magnetic attraction force of the electromagnet column 22 on the mounting shaft 4.

[0037] The adjustable movable device includes an adjustable motor 10 arranged on the base 1, the adjustable motor 10 drives an adjustable screw rod 11, an adjustable movable seat 12 is sleeved and matched with the adjustable screw rod, an adjustable slide groove 17 is opened on the base 1, and an adjustable slider 18 matched with the adjustable slide groove 17 is connected to the lower part of the adjustable movable seat 12, and the adjustable inclined block 16 includes an inclined part and a horizontal part, and the horizontal part is at a high position.

[0038] It should be noted that when the slider 18 is adjusted to adjust the angle of the support arm 5 , the lower end of the push rod 17 is always in cooperation with the horizontal portion.

[0039] A pull rope 15 is arranged between the support 2 and the adjustable movable seat 12, and when the adjustable movable seat 12 pushes the support 2 to move and the adjusting support arm 5 to rotate, the pull rope 15 is in a relaxed state. In the process of adjusting the inclined block 16 to adjust the height of the top rod 17, the pull rope 15 is also in a relaxed state. In the process of the adjusting movable seat 12 driving the support 2 to move, the adjusting movable seat 12 blocks the adjusting slide groove.

[0040] The support 2 is a groove-shaped block, and the lower parts of the two parallel groove-shaped blocks are provided with support sliders 28. The base 1 is provided with a support groove 27 that cooperates with the support slider 28, and the support 2 always covers the support groove 27. The mounting block of the adjustment motor 10 is detachably mounted on the base 1 by bolts.

[0041] The specific operation of this embodiment is as follows: first install the supporting part (support, support arm and plug-in sleeve) on the base 1, so that the support slider 28 is in the support slide groove 27, and then install the pushing part (adjustable movable seat, adjusting screw and adjusting motor) on the base 1, the mounting block of the adjusting motor 10 is locked on the base 1 by bolts, and the adjusting slider 18 is in the adjusting slide groove, then the clamping device and the connecting wires of the adjusting motor are plugged into the base 1, and then the base is plugged into the power socket, the electromagnet column of the clamping device is in the energized state, the installation shaft is magnetically attracted to limit the rotation of the installation shaft, and then the two ends of the pull rope 15 are respectively installed on the support 2 and the adjustable movable seat 12 to complete the installation of the screen adjustment structure, and then the mounting column of the display is inserted into the plug-in sleeve 6 and supported by the top rod 7.

[0042] When in use, the base 1 and the supporting part can be completely separated. After large-scale promotion, the base 1 can be made into a part of an office desktop, and then the supporting part can be added, so as to ensure the overall beauty of the office desktop.

[0043] After that, the operation of returning to the initial position is performed, and the initial reset is performed each time the user leaves; the initial reset is achieved by the adjustment motor 10 driving the adjustment screw 11 to rotate, thereby moving the adjustment movable seat 12 away from the support 1, straightening the pull rope 15, and then driving the support 1 to move through the pull rope until the support slider 28 moves to the end of the support slide groove 27. This is the initial position. When in the initial position, the lower end of the push rod 7 is on the horizontal part of the adjustment bevel block, that is, in the initial position, the push rod 7 is at the highest point.

[0044] When the user sits at the office workstation, the posture camera on the monitor will take a photo of the user, and then calculate the optimal position of the screen adjustment structure of the present application, that is, how much the support moves forward and backward, how much the support arm rotates, and how much the top rod drops; this information is transmitted to the control module in the base 1, and the control module will rotate the adjustment motor 1, and then drive the adjustment movable seat 12 to move forward through the adjustment screw. The movement of the adjustment movable seat 12 is driven by the structure of the motor and the screw, so the accuracy of the movement can be ensured.

[0045] When the adjusting push block 14 contacts the support arm 5, it will drive the support arm 5 and the entire support 1 to move forward together until the bracket reaches the required adjustment position. At the same time, the adjusting movable seat 12 will remember this position. Then, the control module in the base 1 will energize the electromagnet block 8, thereby generating a magnetic attraction force on the iron block 9 to lock the support 2. The state at this time is as follows: Figure 1As shown, the electromagnet column 22 will be powered off, and it only supports the installation axis without limiting its rotation. In this way, the support arm 5 can be driven to rotate upward with the installation axis as the center by adjusting the forward movement of the movable seat 12, and the support arm 5 can be driven to rotate downward by adjusting the backward movement of the movable seat 12. Specifically, the calculated support arm rotation angle is converted into the movable distance of the movable seat 12, and the electromagnet column 22 is powered on again to limit the rotation of the installation axis 4. Then, the height of the push rod needs to be adjusted. After the angle adjustment of the support arm 5 is completed, the height of the push rod is adjusted by adjusting the movable seat 12 to move back so that the bottom of the push rod 7 contacts the inclined part of the adjusting bevel block 16. In this way, the height of the push rod 7 can be adjusted, and then the height of the display can be adjusted. The state at this time is as shown in FIG. Figure 2 As shown, due to the rotation of the support arm, the top rod 7 will also tilt to a certain extent, but the tilt can still be adjusted in height by cooperating with the adjusting bevel block 16;

[0046] After the adjustment is completed, it is necessary to reset. When resetting, first move the movable seat 12 to the position when adjusting the support 2. In this process, the clamping device 20 should be cooperated to loosen the mounting shaft 4, so that the support arm 5 can return to the original angle. Then, the mounting shaft 4 is clamped by the clamping device 20, and then the adjusting motor 10 drives the adjusting screw rod 11 to rotate, so that the movable seat 12 is moved away from the support 1, so that the pull rope 15 is straightened. The state at this time is as follows: Figure 3 As shown, the support 1 is then moved by the pull rope until the support slider 28 moves to the end of the support slot 27, completing the reset. When a user subsequently works, the above adjustment operation based on the human body posture can be repeated.

[0047] Example 2

[0048] like Figure 1-4 and Figure 6-7 As shown, the difference compared with Example 1 lies in the clamping device. The installation shaft 4 of this embodiment is a hollow shaft. The clamping device 20 of this embodiment includes a clamping telescopic pull rod 24 arranged on both outer sides of the mounting seat, and a penetrating clamping hole is opened in the mounting seat 3. The clamping telescopic pull rod 24 is connected to a clamping block 25 that moves horizontally in the clamping hole. The clamping block 25 is a side T-shape, and the clamping block 25 is inserted into the installation shaft 4 and presses the installation shaft 4. The clamping of the installation shaft 4 by the clamping block 25 prevents the installation shaft 4 from rotating.

[0049] Compared with Example 1, the general operation of this embodiment is consistent with that of Example 1, the difference lies in the clamping and loosening of the installation shaft. When the installation shaft needs to be clamped, the electric clamping telescopic pull rod 24 drives the clamping block 25 to move inward, and the part of the clamping block 25 inside the installation shaft 4 continues to move inward, while the part of the clamping block 25 outside the installation shaft will contact the end of the installation shaft 4 and apply pressure to the outside of the installation shaft, thereby limiting its rotation through the pressure at both ends.

[0050] Example 3

[0051] In a specific application process, the clamping structures of Example 1 and Example 2 can be combined, so that the part of the clamping block 25 of Example 2 that is inserted into the installation shaft is an electromagnet column, and the part outside the installation shaft is a plastic material with a large friction coefficient. In this way, when clamping is required, there are two forces to limit the rotation of the installation shaft, one is the magnetic attraction of the electromagnet column, and the other is the pressure of the part of the clamping block 25 outside the installation shaft 4 on both ends of the installation shaft 4.

[0052] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0053] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. The above is only a preferred implementation of the present invention. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the protection scope of the present invention.
