Description

Technical Field

[0001] The utility model relates to the technical field of display bracket devices, in particular to a gas spring desktop display bracket. Background Art

[0002] Nowadays, computers are increasingly used in people's lives and work. Traditional monitor stands have limited adjustment capabilities and cannot meet people's current needs for comfortable and flexible use, reducing fatigue and improving work efficiency. Gas springs are used on display stands, which can move smoothly when users push or pull, and stop at specific positions when moving up and down, providing a convenient operating experience similar to hovering arms. The development of gas spring monitor stands in the display industry has gone through several stages. Early gas spring display stands only provided simple lifting and limited adjustment functions. In the development process of gas spring monitor stands, the design of gas spring monitor stands has been continuously optimized, using new materials and optimizing the structure. From a single bulky structure, it has gradually become more lightweight, beautiful, and diverse and colorful, improving durability and stability.

[0003] Gas springs have a nearly linear elastic operating curve, operating more smoothly than mechanical springs. They also have a slower rebound speed, less dynamic force variation, and are easy to control and install. Gas spring monitor stands are easy to control and rotate, allowing for smoother changes in the display's orientation and providing a more streamlined operating experience. However, gas springs do have limitations. Prolonged periods of disuse or inadequate maintenance can lead to gas leaks, impacting performance. They also emit a gas exhalation sound when compressed or extended.

[0004] Most gas spring monitor stand arms on the market now use nylon as the primary structural component bearing the gas spring's force, though a smaller number utilize die-cast aluminum. Currently, gas spring monitor stands offer relatively simple and quick installation methods, with both clamp-on and through-hole mounting options suitable for most users. Assembly and use are also relatively straightforward: secure the base assembly to the tabletop and insert the lower arm assembly and adjustment arm assembly in sequence. Connections between gas spring monitor stand components are established using through-hole shafts.

[0005] There are generally two ways to connect a monitor to a monitor stand. One is to pre-screw two screws on the monitor, hang the monitor on the stand, and finally screw in the remaining two screws and tighten them together. The other is to disassemble the mainboard, remove it from the adjustment arm, screw it directly to the monitor, and then lock it to the adjustment arm. Monitor stands generally use cable clips and cable ties to hide and modify the monitor cables, making the appearance more neat. Current gas spring brackets have the following main drawbacks:

[0006] (1) Disadvantages of the virtual position of the hole-shaft connection between components:

[0007] When assembling a gas spring monitor stand, insert the lower arm assembly into the base, then the adjustment arm assembly into the lower arm assembly. Gently shaking the two components by hand may reveal noticeable looseness. This is due to excessive clearance between the shafts, which connect the components. This larger clearance reduces resistance when the components rotate, ensuring smooth operation, but it can also cause the product to feel loose. When weighing the product, the larger clearance causes the components to move toward the side receiving the force, creating an appearance of uneven gaps between the components. During operation, the larger clearance causes friction between the shafts, causing them to wear, leading to a loosening of the product over time.

[0008] (2) Disadvantages of monitor cable management wire clips and wire buckles being easily loosened:

[0009] Users use cable clips and cable buckles to store the monitor cables on the monitor stand. When users rotate the product up, down, left, and right, the monitor cables will cause friction and scratches on the cable clips and cable buckles, causing the cable clips and cable buckles to fall off.

[0035] The working principle of the gas spring desktop display stand of the utility model is as follows: The utility model relates to a gas spring desktop display stand, which mainly includes a base assembly, a lower support arm assembly, an adjustment arm assembly and a machine plate adjustment assembly.

[0036] Base Assembly: The base assembly consists of the base gusset plate 4, base top plate 2, top plate screw 1, base top plate rubber pad 3, base plate 7, base plate connector 5, base plate rubber pad 6, and base shaft 8, assembled in sequence. To meet the needs of most desktops on the market, it accommodates desktop thicknesses ranging from 10-80mm and supports both perforated and punched mounting methods. The base shaft 8 is constructed from ADC12 aluminum, die-cast from a blank, then machined to the desired precision dimensions using a CNC lathe and vertical tapping machine. The base plate 7 is constructed from high-quality SPCC cold-rolled steel, extruded into shape using a die.

[0037] The lower arm assembly's lower end is pivotally connected to the base shaft 8 at the upper end of the base assembly via a shaft hole. A shaft sleeve 9 is located between the inner wall of the shaft hole and the base shaft 8, and is secured with bolts. A lower arm cable clip 11 is removably attached to the bottom of the lower arm assembly. The lower arm primarily provides support, increases flexibility, reduces lateral space, increases angle adjustment, and manages wiring harnesses.

[0038] Adjustment arm assembly: The adjustment arm assembly includes an adjustment arm lower connector 13, an adjustment arm upper connector 22, a gas spring assembly and a side decorative cover 18. The gas spring assembly and the side decorative cover 18 are hingedly arranged between the adjustment arm lower connector 13 and the adjustment arm upper connector 22, and the side decorative cover 18 is located on the outside of the gas spring assembly. The adjustment arm shaft 12 at the lower end of the adjustment arm lower connector 13 is rotatably connected to the second shaft hole at the upper end of the lower support arm assembly. A second shaft sleeve is provided between the inner wall of the second shaft hole and the adjustment arm shaft 12 and fixed by bolts. The adjustment arm wire buckle 21 is movably connected to the bottom of the adjustment arm assembly. This assembly has the functions of height adjustment, tilt adjustment, rotation adjustment, and supporting force adjustment. The gas spring achieves the supporting force of the adjustment arm by adjusting the compression force and changing the stroke. The weight range of the supported monitor is 2kg-9kg.

[0039] The board adjustment assembly consists of a plastic adjustment block 23 hinged to a connector 22 on the adjustment arm. Adjustment plates 25 are hingedly attached to the front and rear ends of the other end of the plastic adjustment block 23. Electroplated friction plates 24 are installed between the adjustment plates 25 and the plastic adjustment block 23. The other end of the adjustment plate 25 is pivotally connected to a board 29, which is secured to the desktop monitor via bolts. This allows for adjustment of the monitor's pitch angle and left and right tilt.

[0040] The working principle of the gas spring desktop monitor stand of the utility model is mainly to achieve support and multi-angle adjustment of the monitor through the cooperation between various components.

[0041] 1. The base assembly is stably fixed to the desktop through the combination of base gusset plate 4, base top plate 2 and other parts. The connection between the base shaft 8 and the lower arm assembly allows the lower arm to rotate relative to the base, increasing the adjustment angle.

[0042] 2. The lower arm assembly provides support and connection, while also providing flexibility and wire management, making the entire stand neater and easier to use. The lower arm cable clip 11 assists in organizing the wires.

[0043] 3. The gas spring assembly in the adjustable arm assembly is a key component. By adjusting the compression and travel of the gas spring, the support force of the monitor can be adjusted to accommodate monitors of varying weights. The hinged structure between the lower connector 13 and the upper connector 22, as well as the connection to the lower support arm assembly and the chassis adjustment assembly, enables height, tilt, and rotation adjustment of the monitor. The adjustable arm cable clip 21 organizes the wiring harness at the adjustable arm.

[0044] 4. The board adjustment assembly realizes the pitch angle and left and right head adjustment of the display through the cooperation of the plastic adjustment block 23, the adjustment plate 25 and the electroplated friction plate 24 to meet the different viewing needs of users.

[0045] The operation process of the utility model of a gas spring desktop display bracket is as follows:

[0046] 1. Installation: Depending on the thickness of the desktop, select either a perforated or punched mounting method to secure the base assembly to the desktop. Align the lower axis hole of the lower arm assembly with the base axis 8, insert the axis sleeve 9, and secure with bolts. Align the adjustment arm axis 12 at the lower end of the adjustment arm assembly with the second axis hole at the upper end of the lower arm assembly, insert the second axis sleeve, and secure with bolts. Hinge the plastic adjustment block 23 onto the upper connector 22 of the adjustment arm, and then secure the base plate 29 of the base plate adjustment assembly to the monitor with bolts.

[0047] 2. Adjustment: The monitor's height is adjusted by manipulating the gas spring in the adjustment arm assembly to change its compression force and travel. Gently push the monitor, and the adjustment arm assembly tilts within a certain range to accommodate varying viewing angles. Hold the monitor and rotate it around the connection point of the adjustment arm assembly to adjust the monitor's orientation. Adjust the gas spring's compression force based on the monitor's weight to ensure stable support. Adjust the monitor's pitch and tilt angles by adjusting the angles of the plastic adjustment block 23 and adjustment plate 25 in the baseplate adjustment assembly.

[0048] Furthermore, the gas spring components of gas spring monitor stands currently on the market are mostly made of inexpensive nylon PA6 or expensive aluminum alloy. While nylon PA6 is a relatively inexpensive material, it is relatively soft and can cause irreversible deformation after prolonged stress. There is also the risk of breakage under severe stress conditions, and unusual noises can occur during use. While aluminum alloy components offer high strength and low weight, the high cost of aluminum alloy results in excessive performance within the overall product.

[0049] The solution in this proposal is to use nylon PA66 with 30% glass fiber as the raw material and develop an injection mold. This mold evenly distributes the material within the mold cavity, resulting in a structural component with the strength and toughness to withstand the loads of the gas spring. While the calculated cost is higher than pure nylon PA6, the strength is higher. Compared to aluminum alloy for load-bearing structural components, which are not as strong and light as aluminum alloy, the strength is sufficient for this product.

[0050] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
