Description

Technical Field

[0001] This utility model relates to the field of monitor bracket technology, specifically to an eccentric rotating lifting bracket and a monitor. Background Technology

[0002] With the popularization of computer network technology, computers have become indispensable devices in life and work. Some professions require long-term computer operation, but existing display devices have significant shortcomings: screen height and angle largely depend on manual adjustment. Because of the dynamic changes in human posture during prolonged sitting, such as body swaying and tilting, scientific research shows that only by keeping the face aligned with the center line of the monitor can the health of the cervical and spinal spine be effectively protected; otherwise, chronic strain can easily occur. However, frequent manual adjustment of the display device not only affects work efficiency but also makes it difficult to match dynamic posture in real time, leading to a widespread risk of cervical spondylosis and spinal diseases among people who spend long hours at a desk.

[0003] Currently, most mainstream display stands use a simple snap-fit ​​structure to fix the screen, which has the following drawbacks in its adjustment function: limited height adjustment, with most stands only supporting a limited number of manual height adjustments, unable to achieve stepless precise positioning; poor dynamic stability: existing rotating mechanisms, such as single-axis hinges or ball joints, lack rigid locking ability after adjustment, making the screen susceptible to shaking or sagging due to external forces or the weight of the device, especially after adjusting the angle, making it difficult to maintain a stable posture; difficulty in adapting to multiple users: in public scenarios, such as sales demonstrations, users of different heights need to repeatedly adjust the screen, and the accumulation of gaps and insufficient rigidity in the mechanical structure will cause the screen to wobble, which not only reduces the customer's viewing experience but also aggravates the wear and loosening of the adjustment mechanism.

[0004] Therefore, there is a need for a lifting bracket with a highly stable eccentric rotation structure that can effectively suppress screen shaking during multi-dimensional adjustment and achieve precise positioning and long-term stable hovering. Summary of the Invention

[0005] One of the purposes of this utility model is to provide an eccentric rotating lifting bracket, which solves the problems of existing brackets lacking eccentric rotation function and having insufficient rotation stability.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] An eccentric rotating lifting bracket includes a lifting assembly and an eccentric rotating assembly. The eccentric rotating assembly is mounted on the lifting assembly and includes multiple rocker arm mechanisms, a driver, a drive wheel, a fixed plate, and a tray. The fixed plate is fixedly connected to the driver, and the drive wheel is located on the output end of the driver. One end of each of the multiple rocker arm mechanisms is engaged with the drive wheel, and the tray is rotatably connected to the other end of each of the multiple rocker arm mechanisms. This allows the tray to rotate and move eccentrically, either individually or simultaneously, thus alleviating fatigue during prolonged use and facilitating relocation. It has a wide range of applications.

[0008] Furthermore, the rocker arm mechanism includes a drive wheel, a rocker arm, and a rotating shaft. The drive wheel is rotatably connected to the fixed plate, one end of the rocker arm is connected to the drive wheel, and the rotating shaft is rotatably connected to the other end of the rocker arm and connected to the tray, outputting a stable rotational motion to the tray.

[0009] Preferably, the multiple rocker arm mechanisms are distributed around the center of the driver, resulting in stable output motion.

[0010] Furthermore, the rocker arm includes a fixed part, an extension part, and a rotating part connected in sequence. The horizontal angle between the extension part and the fixed plate is A, where 0° < A ≤ 50°, to prevent interference and adjust the forward extension distance of the tray.

[0011] Furthermore, the lifting assembly includes a housing, a column, and a base. The eccentric rotating assembly is disposed within the housing. The housing is lifted and connected to the column, and the base is connected to the bottom of the column for support and installation.

[0012] Furthermore, the column is equipped with a slide, a lifting screw, and a nut sleeve. A sliding groove along the height direction is provided on one side wall of the column. The slide is slidably connected in the sliding groove. The lifting screw is vertically installed in the column. The nut sleeve is connected to one side wall of the slide and is helically connected to the lifting screw to achieve stable lifting movement.

[0013] Preferably, both the drive wheel and the driving wheel are gears, which provide stable transmission and strong load-bearing capacity.

[0014] Preferably, a reinforcing part is provided on one end face of the tray, and the other ends of the plurality of rocker arm mechanisms are rotatably connected to the reinforcing part to prevent the tray from shaking and deforming under pressure.

[0015] As an even better feature, the rocker arm is designed as a hollow rod; the tray is provided with multiple sets of mounting holes, which reduces weight, improves load-bearing capacity and movement flexibility, and meets the installation requirements of different panels.

[0016] The second objective of this invention is to provide a display that solves the problems associated with the use of existing displays.

[0017] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0018] A display includes the aforementioned eccentric rotating lifting bracket and a screen, the screen being mounted on the eccentric rotating lifting bracket. Long-term use can alleviate fatigue and is convenient for people in different positions and viewing heights, making it highly adaptable.

[0019] The beneficial effects of this utility model are as follows:

[0020] (1) The eccentric rotating lifting bracket is equipped with a lifting component and an eccentric rotating component, which can realize the lifting adjustment and eccentric rotation of the supported object. The posture of the supported object remains unchanged during rotation. The eccentric rotating component consists of multiple rocker arms. The multiple rocker arms are driven by the same driver to drive the tray to rotate eccentrically. The tray moves stably and bears a reliable load. With the lifting component, it can be used at different heights. It can prevent cervical and lumbar spine problems caused by long-term screen viewing and play a relaxing role.

[0021] (2) The rocker arm mechanism on the eccentric rotating lifting bracket includes a rocker arm that connects the drive wheel and the rotating shaft. The rocker arm supports the eccentric rotation action and is inclined outward along the end face of the fixed plate, so that multiple rocker arms can support the tray to rotate stably at the same time, which improves the stability of rotation and meets the requirements for supporting the screen. In addition, the lifting component is driven by a lead screw and a nut sleeve and has self-locking capability. The slide is guided by the slide groove on the column. The lifting action is accurate and stable, meeting the needs of different users. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0036] Example 1

[0037] like Figures 1-8As shown, this embodiment discloses an eccentric rotating lifting bracket, including a lifting assembly 1 and an eccentric rotating assembly 2. The eccentric rotating assembly 2 is mounted on the lifting assembly 1 and includes multiple rocker arm mechanisms 23, a driver 21, a drive wheel 22, a fixed plate 24, and a tray 27. The fixed plate 24 is fixedly connected to the driver 21, and the drive wheel 22 is mounted on the output end of the driver 21. One end of each of the multiple rocker arm mechanisms 23 is engaged with the drive wheel 22, and the tray 27 is rotatably connected to the other end of each of the multiple rocker arm mechanisms 23. The multiple rocker arm mechanisms 23 can rotate the fixed plate 24 around a fixed center while keeping its posture unchanged, adjusting the viewing direction and reducing fatigue. The lifting assembly 1 can drive the eccentric rotating assembly 2 to move up and down as a whole, meeting the needs of different users. The two components working together can adjust the viewing position without moving the bracket, thus expanding the range of applications.

[0038] Furthermore, the rocker arm mechanism 23 includes a drive wheel 231, a rocker arm 232, and a rotating shaft 233. The drive wheel 231 is rotatably connected to the fixed plate 24. One end of the rocker arm 232 is connected to the drive wheel 231, and the rotating shaft 233 is rotatably connected to the other end of the rocker arm 232. The rotating shaft 233 is connected to the tray 27. The drive wheel 231 meshes with the drive wheel 22 to drive the rocker arm 232 to rotate. The rotating shaft 233 transmits the rotational motion to the fixed plate 24 without affecting the posture of the fixed plate 24. It can change the viewing posture of the person without affecting the viewing and use, so that the person can relax when viewing and relieve fatigue.

[0039] Preferably, multiple rocker arm mechanisms 23 are distributed around the center of the driver 21, and multiple drive wheels 231 are driven by one driver 21 to rotate multiple rocker arms 232. The rotation is highly stable and the load on the driver 21 is uniform, making it less prone to backlash.

[0040] Furthermore, the rocker arm 232 includes a fixed part 2321, an extension part 2322, and a rotating part 2323 connected in sequence. The horizontal angle between the extension part 2322 and the fixed plate 24 is A, where 0° < A ≤ 50°. The fixed part 2321 is connected to the outward end of the drive wheel 231. The extension part 2322 extends outward at an angle to prevent interference between the rocker arms 232 during rotation. The rotating part 2323 cooperates with the rotating shaft 233 to separate the free rotational motion and output only a stable oscillating motion to drive the tray 27 to rotate around the center of the drive wheel 22.

[0041] Furthermore, the lifting assembly 1 includes a housing 11, a column 12, and a base 13. The eccentric rotating assembly 2 is disposed inside the housing 11. The housing 11 is lifted and connected to the column 12. The base 13 is connected to the bottom of the column 12. The housing 11 is used to protect the moving element and prevent foreign objects from intruding or causing damage to external objects. The base 13 is used to install the bracket.

[0042] Furthermore, the column 12 is equipped with a slide 121, a lifting screw 123, and a nut sleeve 124. A slide groove 122 along the height direction is provided on one side wall of the column 12. The slide 121 is slidably connected in the slide groove 122. The lifting screw 123 is vertically installed in the column 12. The nut sleeve 124 is connected to one side wall of the slide 121 and is screwed to the lifting screw 123. The lifting screw 123 and the nut sleeve 124 have a self-locking capability and can stop at any height. The slide 121 is guided by the slide groove 122 to prevent shaking during lifting and moving, thereby improving the stability and load-bearing capacity of lifting and moving.

[0043] The lifting screw 123 is fixed at both ends inside the column 12 and is driven to rotate by the motor 125, which drives the slide table 121 to slide along the height direction to achieve height adjustment.

[0044] Preferably, both the drive wheel 22 and the driving wheel 231 are gears, including helical gears, spur gears and herringbone gears, which can be selected according to load and stability requirements.

[0045] Preferably, a reinforcing part 26 is provided on one end face of the tray 27, and the other ends of the multiple rocker arm mechanisms 23 are rotatably connected to the reinforcing part 26. The tray 27 is formed of sheet metal, and the reinforcing part 26 is an annular protrusion on the tray 27, which improves the connection strength, prevents deformation during rotation, and improves the service life.

[0046] More preferably, the rocker arm 232 is configured as a hollow rod to reduce the mass of the moving parts and improve the accuracy and load-bearing capacity of the movement; the tray 27 is provided with multiple sets of mounting holes 25, which are used to install flat plates or panels of different specifications, making it widely applicable and easy to install.

[0047] Example 2

[0048] like Figure 9 As shown, this embodiment also discloses an eccentric rotating component 2, including two rocker arm mechanisms 23. The driving wheels 231 on the two rocker arm mechanisms 23 are engaged with the drive wheels 22. The center line connecting the two driving wheels 231 is perpendicular to the ground, which reduces the volume of the eccentric rotating component 2 and is suitable for installation on screens 3 or panels with small loads.

[0049] Example 3

[0050] like Figure 10 As shown, this embodiment also discloses an eccentric rotating component 2, which includes three rocker arm mechanisms 23. The drive wheels 231 on the three rocker arm mechanisms 23 are evenly distributed around the center of the drive wheel 22, forming a three-point support for the tray 27. This can reduce the number of moving parts while ensuring load and transmission stability, and achieve a balance between load and structural complexity.

[0051] Example 4

[0052] like Figure 11 As shown, this embodiment also discloses an eccentric rotating assembly 2, including four rocker arm mechanisms 23. The drive wheels 231 on the four rocker arm mechanisms 23 are evenly distributed around the center of the drive wheel 22, forming four-point support for the tray 27. Specifically, the lines connecting each drive wheel 231 form a square, which can improve the load capacity and movement stability, and extend the service life of the moving elements.

[0053] Example 5

[0054] See Figure 8 This embodiment also discloses a display, including an eccentric rotating lifting bracket and a screen 3, wherein the screen 3 is disposed on the eccentric rotating lifting bracket.

[0055] The process of using the monitor is as follows:

[0056] When rotating, the driver 21 is activated, and the drive wheel 22 drives the meshing drive wheel 231 to rotate. The drive wheel 231 drives the rocker arm 232 to swing around a fixed point on the fixed plate 24. The rotating shaft 233 at the end of the rocker arm 232 pushes the tray 27 to rotate eccentrically. The screen 3 deflects around the center of the drive wheel 22. For height adjustment, the machine 125 drives the lifting screw 123 to rotate, and the nut sleeve 124 moves along the axial direction of the lifting screw 123, causing the slide table 121 to slide vertically in the slide groove 122. The housing 11 and the internal eccentric rotating assembly 2 are raised and lowered as a whole, realizing stepless height adjustment of the screen 3. The self-locking characteristic of the screw ensures stable suspension at any position. When working in tandem, the height and rotation are adjusted synchronously when the user's sitting posture changes, realizing the translation of the screen 3. This meets the viewing needs of people in different positions or those moving around with the same person. It can also achieve eye-tracking movement.

[0057] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and any modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
