Description
Technical Field
[0001] This utility model belongs to the field of industrial equipment technology, and specifically relates to a display rocker arm device. Background Technology
[0002] In existing technologies, to facilitate the adjustment of the monitor's height and angle, the monitor is usually mounted on an adjustable monitor stand. Due to factors such as the user's height, operating position, and operating angle, users often need to manually adjust the monitor's angle and height to suit their needs. When users frequently need to change the direction and angle in actual use, manual adjustment is very inconvenient, time-consuming, and laborious. At the same time, since adjustable monitor stands generally use a gear structure for connection and are fixed to the device, the hinge joints are prone to gaps after long-term use, causing wobbling. Furthermore, frequent movement of the monitor stand can also cause wear and tear on its internal cables and generate noise. Utility Model Content

Detailed Implementation
[0043] This utility model will be further described in detail below with reference to the accompanying drawings:
[0044] Please see Figures 1 to 4 As shown, this utility model provides a display rocker arm device, including: a main arm 1, a secondary arm 2 and a display support column 3. One end of the secondary arm 2 is connected to the main arm 1 through a first rotating mechanism 4, and the other end is connected to the display support column 3 through a second rotating mechanism 5. By setting the dual rotating nodes of the first rotating mechanism 4 and the second rotating mechanism 5, the display 7 connected to the display support column 3 can be flexibly adjusted at multiple angles in the horizontal and vertical directions to meet different viewing angle requirements.
[0045] Please see Figure 5As shown, an electric support rod 31 is installed inside the monitor support column 3. The lower end of the electric support rod 31 is fixed to the monitor support column 3, and a connecting slider 32 is fixed to the upper end of the electric support rod 31. The electric support rod 31 extends and retracts, causing the connecting slider 32 to move up and down. Four telescopic cylinders 33 are connected to the side of the connecting slider 32 facing the monitor 7. The telescopic cylinders 33 are connected to the display actuator 71 fixed on the monitor 7 through a universal ball joint connector 34. The multi-angle adjustment of the monitor 7 is achieved through the cooperation of the telescopic cylinders 33 and the universal ball joint connector 34. A gyroscope 72 is installed inside the display actuator 71 for real-time feedback of the monitor 7's attitude. A display sensor 73 facing the user is installed on the monitor 7 for capturing the user's position.
[0046] Please see Figure 8 As shown, the display sensor 73, gyroscope 72, electric strut 31, and telescopic cylinder 33 are all connected to the control module. The control module is configured to receive the user position captured by the display sensor 73 and the display attitude information fed back in real time by the gyroscope 72, drive the electric strut 31 to extend and retract to drive the connecting slider 32 to move up and down, thereby adjusting the height of the display 7; at the same time, drive the four telescopic cylinders 33 to perform differentiated extension and retraction actions, and drive the display 7 to change its orientation through the universal ball joint connector 34, so as to realize the automatic adjustment of the orientation and position of the display 7.
[0047] Please see Figure 5 As shown, a slide rail connecting plate 35 is fixed to the side of the connecting slider 32 facing the display 7. The telescopic cylinder 33 and the universal ball connector 34 are both located inside the slide rail connecting plate 35. The telescopic cylinder 33 passes through one side of the slide rail connecting plate 35 and connects to the connecting slider 32, while the universal ball connector 34 passes through the opposite side of the slide rail connecting plate 35 and connects to the display actuator 71. By setting the slide rail connecting plate 35 to enclose the telescopic cylinder 33 and the universal ball connector 34, it can prevent external dust from entering the telescopic cylinder 33 and the universal ball connector 34, reducing mechanical wear; it can also enhance the bending / torsional stiffness and effectively suppress the shaking of the display 7.
[0048] Please see Figure 5 As shown, two ball bearing tracks 36 are fixed inside the monitor support column 3. The ball bearing tracks 36 extend along the axial direction of the monitor support column 3. The two sides of the connecting slider 32 are respectively slidably engaged with the corresponding ball bearing tracks 36, thereby enabling the connecting slider 32 to move up and down along the ball bearing tracks 36. By using the ball bearing tracks 36 to slide with the connecting slider 32, the movement of the connecting slider 32 is smoother and less strenuous, greatly reducing wear. Furthermore, the ball bearing tracks 36 can avoid uneven resistance caused by dust or slight deformation, ensuring a smooth and uninterrupted lifting process.
[0049] Furthermore, such as Figure 5As shown, a spiral spring 37 is fixedly installed on the connecting slider 32, and one end of the spiral spring 37 is fixed to the top of the display support column 3. When the connecting slider 32 moves downward, the spiral spring 37 generates elastic deformation and forms an upward restoring force to balance the weight of the display 7 and make the position of the display 7 stable.
[0050] Please see Figure 6 As shown, the first rotating mechanism 4 includes a circular rotating frame 41, a connecting pipe 42, a first hollow rotating platform 43, and a first motor 44 arranged sequentially from top to bottom in the vertical direction.
[0051] like Figure 6 As shown, the circular boom 41 includes a first part 411 embedded in the main boom 1 and a second part 412 embedded in the secondary boom 2; in this embodiment, the circular boom 41 has a T-shaped structure, including a first part 411 extending vertically and a second part 412 extending horizontally, as shown. Figure 6 As shown, the first part 411 is inserted into the main boom 1, and the second part 412 is exposed above the main boom 1 and embedded in the bottom of the secondary boom 2, thereby connecting the main boom 1 and the secondary boom 2 together through the rotating frame 41; an anti-wear sleeve 45 is provided between the first part 411 and the inner wall of the main boom 1, which effectively reduces the wear between the rotating frame 41 and the inner wall of the main boom 1; an anti-wear pad 46 is provided between the second part 412 and the upper surface of the main boom 1, which effectively reduces the wear between the rotating frame 41 and the upper surface of the main boom 1.
[0052] like Figure 6 As shown, the connecting pipe 42 is connected to the lower part of the rotating frame 41 and the anti-wear sleeve 45. In this embodiment, the connecting pipe 42 is arranged inside the main boom 1 and located below the rotating frame 41 and the anti-wear sleeve 45. An anti-wear lower sleeve 47 is provided between the connecting pipe 42 and the first part 411 of the rotating frame 41. By providing the anti-wear lower sleeve 47, the wear between the connecting pipe 42 and the rotating frame 41 is effectively reduced.
[0053] like Figure 6 As shown, the first hollow rotating platform 43 is located below the main boom 1 and is fixedly connected to the connecting pipe 42; the first motor 44 is driven and connected to the first hollow rotating platform 43 and electrically connected to the control module; the control module drives the first hollow rotating platform 43 to rotate by controlling the first motor 44, and then drives the circular rotating frame 41 and the secondary boom 2 to rotate synchronously through the connecting pipe 42.
[0054] Please see Figure 7 As shown, the second rotating mechanism 5 includes, from top to bottom, the following components arranged in a vertical direction: a rotating connecting column 51, a second hollow rotating platform 52, and a second motor 53.
[0055] like Figure 7As shown, the swivel link 51 is installed in the inner cavity of the secondary boom 2. An anti-wear ring 54 is provided between the upper part of the swivel link 51 and the secondary boom 2. The anti-wear ring 54 effectively reduces the wear between the swivel link 51 and the secondary boom 2.
[0056] like Figure 7 As shown, the second hollow rotating platform 52 is located below the secondary boom 2. The second hollow rotating platform 52 is connected to the rotating connecting column 51 and a rotating wear plate 55 is provided between them. By setting the rotating wear plate 55, the wear between the second hollow rotating platform 52 and the rotating connecting column 51 is effectively reduced. The second motor 53 is driven and connected to the second hollow rotating platform 52 and electrically connected to the control module.
[0057] like Figure 7 As shown, the bottom of the monitor support column 3 extends into the interior of the secondary arm 2 and is fixed to the swivel column 51. The control module drives the second hollow rotating platform 52 to rotate by controlling the second motor 53, thereby driving the swivel column 51 and the monitor support column 3 to rotate synchronously.
[0058] Please see Figures 1 to 4 As shown, the monitor arm device also includes a keyboard assembly 6. The keyboard assembly 6 includes a keyboard base 61, a keyboard connecting plate 62 fixed to the keyboard base 61, and a keyboard pad 63 fixedly connected to the keyboard base 61 and the keyboard connecting plate 62. The keyboard base 61 is installed at the bottom of the secondary arm 2 and fixed to the rotating connecting column 51. A rotating plate 55 is disposed between the keyboard base 61 and the rotating connecting column 51. The rotating connecting column 51 drives the keyboard assembly 6 to rotate synchronously with the monitor support column 3. In this embodiment, as... Figure 3 As shown, the keyboard connection plate 62 is fixed to one end of the keyboard base 61 near the monitor support column 3, and the keyboard pad 63 is fixed to the keyboard base 61 with one end inserted into the groove of the keyboard connection plate 62. The keyboard pad 63 has an area for placing the mouse and keyboard for user convenience.
[0059] Please see Figure 1 , Figure 2 As shown, a touch screen 631 is provided on the keyboard pad 63. The touch screen 631 is electrically connected to the control module. By double-clicking the right area of the touch screen 631, the working state of the display arm device can be switched between manual mode and automatic mode. When in manual mode, the height position of the display 7 can be manually adjusted by sliding the touch screen 631, and the secondary arm 2 can be manually rotated left and right by using the left button 632 and right button 633 provided on the keyboard pad 63.
[0060] Please see Figure 1 , Figure 2As shown, a left sensor 11 and a right sensor 12 are fixedly installed at predetermined positions on the left and right sides of the main boom 1, respectively. Both the left sensor 11 and the right sensor 12 are electrically connected to the control module. When the secondary boom 2 rotates to the left to trigger the left sensor 11, the control module controls the secondary boom 2 to stop the left rotation. When the secondary boom 2 rotates to the right to trigger the right sensor 12, the control module controls the secondary boom 2 to stop the right rotation. By configuring the left sensor 11 and the right sensor 12, collisions caused by excessive rotation angle of the secondary boom 2 can be avoided.
[0061] It is worth noting that both the first rotating mechanism 4 and the second rotating mechanism 5 have built-in pressure sensing modules, which are used to monitor the joint pressure at the connection positions of the main boom 1 and the secondary boom 2, and the connection positions of the secondary boom 2 and the display support column 3, respectively, to prevent overload failures. Figure 8 As shown, the pressure sensing module is electrically connected to the control module, and the control module is electrically connected to a buzzer installed inside the display arm device. When the pressure sensing module of the first rotating mechanism 4 detects an overload at the connection position between the main arm 1 and the secondary arm 2, the control module controls the buzzer to emit a single-tone alarm at intervals. When the pressure sensing module of the second rotating mechanism 5 detects an overload at the connection position between the secondary arm 2 and the display support column 3, the control module controls the buzzer to emit a double-tone alarm at intervals to remind the user of the overload. The buzzer continues to sound the alarm until the pressure drops below the safe threshold.
[0062] In this embodiment, the first pressure sensing module is installed inside the circular frame 41 of the first rotating mechanism 4 to monitor the pressure at the connection position between the main boom 1 and the secondary boom 2 in real time. The second pressure sensing module is installed inside the rotating column 51 of the second rotating mechanism 5 to monitor the pressure at the connection position between the secondary boom 2 and the display support column 3 in real time, preventing overload failures. Both pressure sensing modules are electrically connected to the control module, which is electrically connected to a buzzer installed inside the display rocker arm device. After the pressure sensing module detects an overload, it sends a signal to the control module, which triggers the buzzer to sound an alarm. One beep at intervals indicates an overload at the connection between the main boom 1 and the secondary boom 2, and two beeps at intervals indicate an overload at the connection between the secondary boom 2 and the display support column 3. This allows the user to quickly and accurately locate the location of the overload failure and take timely action.
[0063] In some embodiments, the main boom 1 is also provided with a cable tray storage compartment for easy cable routing. The cable tray storage compartment is covered with an anti-friction coating to reduce friction on the cable.
[0064] The working principle of the display rocker arm device provided by this utility model is as follows:
[0065] The monitor rocker arm device is activated. The control module controls the first motor 44 to drive the first hollow rotating platform 43 to rotate, which in turn drives the secondary arm 2 to rotate. At the same time, it controls the second motor 53 to drive the second hollow rotating platform 52 to rotate, which in turn drives the monitor support column 3 and the keyboard assembly 6 to rotate synchronously. The display sensor 73 on the monitor 7 captures the user's position in real time. After the control module receives the user's position captured by the display sensor 73 and the monitor's posture information fed back in real time by the gyroscope 72, it drives the electric support rod 31 and the telescopic cylinder 33. The extension and retraction of the electric support rod 31 causes the connecting slider 32 to move up and down to adjust the height of the monitor 7. The differentiated extension and retraction actions of the four telescopic cylinders 33, through the universal ball joint connector 34, drive the monitor 7 to change its orientation, realizing automatic and precise adjustment of the orientation and position of the monitor 7, saving time and effort. Since the main boom 1 is equipped with a left sensor 11 and a right sensor 12, when the secondary boom 2 moves to the left and triggers the left sensor 11, or moves to the right and triggers the right sensor 12, the left sensor 11 or the right sensor 12 sends a signal to the control module. The control module then controls the secondary boom 2 to stop moving to avoid collisions. Because the first rotating mechanism 4 is equipped with wear-resistant anti-friction sleeves 45, anti-friction pads 46, and anti-friction lower sleeves 47, wear on the first rotating mechanism 4 is effectively reduced, extending its service life. Similarly, the second rotating mechanism 5 is equipped with wear-resistant anti-friction rings 54 and wear plates 55, effectively reducing wear on the second rotating mechanism 5 and extending its service life. The first rotating mechanism 4 and the second rotating mechanism 5 also have built-in pressure sensing modules that can monitor joint pressure in real time and prevent overload failures. When the pressure sensing module detects an overload, the control module triggers a buzzer alarm to alert the user of the overload. The display rocker arm device provided by this utility model can also switch the operating state of the display rocker arm device to manual or automatic mode by double-clicking the right area of the touchscreen 631. When the user switches the working mode of the monitor rocker arm device to manual mode, the height of the monitor 7 can be manually adjusted by sliding the touch screen 631, and the secondary arm 2 can be manually rotated left and right by using the left button 632 and right button 633 on the keyboard pad 63.
