Detailed Implementation

[0026] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1-4 As shown, the present invention provides a multi-angle adjustable display arm, including a mounting base 1, a column 11 fixed on the upper side of the mounting base 1, multiple sets of clamping seats 12 detachably mounted on the column 11, a base 13 fixed on the front side of the clamping seats 12, and a support arm 14 mounted on the base 13.

[0028] The clamping base 12 includes a housing 121, a fixed clamping plate 122 fixed on the left side of the housing 121, a sliding block 123 slidably disposed inside the housing 121, a sliding clamping plate 124 fixed on the right side of the sliding block 123, a threaded hole 125 opened in the middle of the sliding block 123, a first screw 126 rotatably mounted on the left inner wall of the housing 121 and threadedly connected to the threaded hole 125, and a knob 127 rotatably mounted on the left side of the housing 121, the knob 127 being connected to the first screw 126;

[0029] The support arm 14 includes a first rotating block 141 damped and rotatably mounted on the upper side of the base 13, the first rotating block 141 is connected to a first connecting arm 142, the end of the first connecting arm 142 is damped and rotatably mounted to a second rotating block 143, the upper end of the second rotating block 143 is damped and hinged to a second connecting arm 144, and the end of the second connecting arm 144 is connected to a damping rotating seat 145.

[0030] The damping rotating seat 145 is detachably connected to a connecting component.

[0031] The connecting component is the monitor connector 2.

[0032] The support arm 14 is composed of a first connecting arm 142 and a second connecting arm 144. The two are connected by damped rotation and damped hinge. The basic principle of damped connection is to apply friction or resistance to the moving parts of the support frame through a damping device, so that it can move smoothly and slowly when adjusting the angle or height, and maintain a stable position after the external force stops.

[0033] Damping devices generally consist of a damper, a damping shaft, and damping components;

[0034] Dampers: They are typically composed of hydraulic, pneumatic, or mechanical friction elements that generate a damping effect through internal fluid resistance or friction.

[0035] Damping shaft: Used in rotary joints, damping is achieved through the friction between the shaft and the bearing.

[0036] Damping components: such as a combination of springs and friction plates, which use spring pressure to bring the friction plates into contact with moving parts, generating frictional resistance.

[0037] Generally speaking, damping devices are implemented in three ways: friction damping, hydraulic damping, and pneumatic damping.

[0038] Friction damping: It generates resistance through friction between metals or plastics. It has a simple structure but a limited range of damping force adjustment.

[0039] Hydraulic damping: Damping is achieved by utilizing the flow resistance of hydraulic oil in a closed cavity. The damping force is stable and adjustable, but the cost is relatively high.

[0040] Pneumatic damping: It generates resistance through the compression and release of gas, has a fast response speed, and is suitable for scenarios that require rapid adjustment.

[0041] The damping connection method in this application can be implemented by the friction damping method mentioned above, which will not be elaborated here;

[0042] When using the device, the user first installs the entire device by connecting the mounting base 1 to the table body, with the column 11 in a vertical position.

[0043] The monitor connector 2 connected to the end of the support arm 14 is connected to the computer monitor. The computer monitor has a mounting position that matches the monitor connector 2 on the back and four rectangular threaded mounting holes. The monitor connector 2 has through holes that match the threaded mounting holes. After aligning the monitor connector 2 with the mounting position of the computer monitor, screws are screwed into the threaded mounting holes for connection.

[0044] The support arm 14 is fixed to the column 11 via the clamping seat 12. The user can rotate the first screw 126 by turning the knob 127 in the forward or reverse direction, which can drive the sliding block 123 to slide left and right in the housing 121, thereby adjusting the distance between the sliding clamp 124 and the fixed clamp 122. When installing the clamping seat 12, first move the sliding clamp 124 away from the fixed clamp 122, place the sliding clamp 124 and the fixed clamp 122 on the column 11, and then turn the knob 127 to move the sliding plate clamp 124 closer to the fixed clamp 122 until the sliding clamp 124 is in tight contact with the side wall of the column 11, and then the clamping seat 12 is fixedly installed on the column 11.

[0045] With the above installation method, the monitor is installed on the support arm of this application. The first rotating block 141 can realize the left and right rotation of the first connecting arm 142, and the second rotating block 143 can realize the left and right rotation of the second connecting arm 144. The second connecting arm 144 is damped and hinged to the second rotating block 143, so the second connecting arm 144 can be adjusted up and down. The monitor connecting bracket 2 is connected to the damping rotating seat 145, so the flip angle of the monitor can be changed. When the user adjusts the monitor angle or height, the moving parts of the support arm move against the damping force. The magnitude of the damping force is proportional to the movement speed. The faster the speed, the greater the resistance, thereby slowing down the movement speed. After the external force stops, the damping force stops the moving parts in the required position, avoiding displacement due to gravity or inertia.

[0046] Therefore, after connecting the monitor through the support arm 14 of this application, the monitor can be adjusted at multiple angles. Users can freely adjust the height, tilt, and rotation angle of the monitor according to their height, sitting posture, and viewing angle, avoiding cervical and shoulder fatigue caused by prolonged head-down or head-up posture.

[0047] By dynamically adjusting the monitor position, it reduces muscle tension and strain caused by fixed postures, making it especially suitable for people who work or play games for long periods of time.

[0048] The clamping base 12 can be adjusted in height relative to the column 11, thereby adjusting the overall height of the support arm 14, making the overall adjustment range of the support arm 14 larger and suitable for more people;

[0049] The column 11 can hold two or more support arms 14, which can connect multiple monitors. Taking a dual-screen setup as an example, users can open documents or applications on one screen while viewing reference materials, tools, or performing other operations on another screen, reducing page switching time and improving work efficiency.

[0050] Dual-screen setups effectively increase the display area, allowing users to view more content simultaneously. This significantly improves efficiency, especially when handling complex tasks such as programming, design, and data analysis.

[0051] In entertainment scenarios, users can watch videos or play games on one screen while chatting, browsing the web, and doing other things on another screen without interfering with each other.

[0052] The connecting component is tray 21.

[0053] The tray 21 can be used to support electronic products such as mobile phones or tablets. Users can replace the connecting parts as needed. When users are using the monitor for entertainment or work, they can use another support arm 14 to support the electronic products, making it suitable for more usage scenarios.

[0054] Since the clamping base 12 in this application can be detached from the column 11, the user can remove the support arm 14 of this application. When the user is engaged in outdoor activities, the user can clamp the clamping base 12 onto the table or table leg, and use the tray 21 on the support arm 14 to support electronic products, thus increasing the number of usage scenarios.

[0055] Similarly, the support arm 14 of this application can be installed in the kitchen or bedroom to reduce hand fatigue, and is especially suitable for users who watch videos, live broadcasts or participate in activities for a long time.

[0056] The damping rotating seat 145 is fixed with a U-shaped seat 1451, and the connecting component 1451 is fixed with a connecting block 22 that slides in the U-shaped seat 1451. The connecting block 22 and the U-shaped seat 1451 are connected by bolts.

[0057] The connecting component 1451 slides within the U-shaped seat 1451 via the connecting block 22. The connecting block 22 and the U-shaped seat 1451 can be fixedly connected by bolts. Users only need to unscrew the bolts to remove the connecting component 1451, making it convenient for users to replace different types of connecting components.

[0058] The tray 21 is provided with a number of heat dissipation holes 211; when electronic products are placed on the tray 21, the heat dissipation holes 211 help to dissipate heat from the electronic products.

[0059] The tray 21 has a wireless charging module 212 in the middle; the wireless charging module 212 integrates a Qi 2.0 wireless charging board, supports 15W fast charging, adopts an NXP chip solution, supports foreign object detection (FOD) and over-temperature protection, and can wirelessly charge electronic products, making it more convenient for users.

[0060] A cable tie 1421 is provided on the lower side of the first connecting arm 142; the cable tie 1421 is used to constrain the cable of the monitor or wireless charging module 212, making the desktop tidier.

[0061] The inner sides of the fixed clamping plate 122 and the sliding clamping plate 124 are provided with anti-slip pads, and the left and right sides of the column 11 are provided with anti-slip textures 111. The anti-slip pads on the inner sides of the fixed clamping plate 122 and the sliding clamping plate 124 can increase the friction force, so that it has very good stability when installed in other positions. The anti-slip textures 111 on the column 11 have the effect of increasing the friction force, and the clamping seat 12 is more stable when installed on the column 11.

[0062] The mounting base 1 is U-shaped. A second screw 3 is rotatably mounted on the lower side of the mounting base 1. An abutment block 31 is connected to the upper end of the second screw 3, and a handle 32 is fixed to the lower end of the second screw 3. The U-shaped mounting base 1 is installed on the table. By rotating the handle 32, the second screw 3 is rotated, so that the abutment block 31 moves upward and abuts against the table, thus fixing the mounting base 1 on the table.

[0063] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
