Description

Technical Field

[0001] This utility model belongs to the field of monitor bracket technology, and specifically relates to a monitor suspension assembly, particularly a solution that uses spring force to counteract load. Background Technology

[0002] Cantilever brackets are widely used for supporting or wall-mounting monitors and medical equipment. Most cantilever brackets employ a four-bar linkage mechanism for height adjustment, and include a vertical axis for a second support base with two additional arms to fix the device to a wall or tabletop, and a horizontal axis for the second support base to hold the equipment. This allows for adjustment in distance, left / right, and tilt angles, meeting all-around adjustment needs. Among these, tilt angle adjustment directly affects the user's usage scenario. For example:

[0003] CN202421096487.3 discloses a pitch-adjustable suspension assembly, the main body of which includes a suspension seat, a connecting seat, and a horizontal shaft connecting the two. A damping structure and a locking device are provided between the suspension seat and the connecting seat. The locking device includes a first friction block and a second friction block with inclined surfaces engaging, and an adjusting bolt. The first friction block is disposed in a groove of the connecting seat, and its friction surface abuts against the circumferential surface of the friction wheel. The second friction block is threadedly engaged with the adjusting bolt, which is rotatably positioned on the connecting seat. Rotating the adjusting bolt drives the second friction block to slide, and the inclined surfaces drive the first friction block to press against the circumferential surface of the friction wheel to lock it in place. This structure is equipped with a locking device, which helps to maintain the stability of the suspension seat's support angle and effectively prevents accidents. Regarding the load-bearing capacity of the suspension seat, torsion springs are used, with two torsion springs sleeved on the horizontal shaft, requiring a larger mating space between the suspension seat and the connecting seat.

[0004] The object of this invention is to find a more reasonable technical solution. Summary of the Invention

[0005] The purpose of this invention is to design a display suspension assembly that uses a spring to bear the load and works in conjunction with a friction plate to form a freely positionable display.

[0006] The present invention is implemented as follows: a display suspension assembly includes a suspension seat, a connecting seat, and a horizontal shaft connecting the two, and a damping structure is provided between the suspension seat and the connecting seat; characterized in that: a pair of lugs are rotatably riveted to the rear of the suspension seat, the lugs are clamped on both sides of the connecting seat and are passed through by the horizontal shaft to form a rotatable positioning; a traction shaft is also provided above the lugs through which the horizontal shaft passes, and a spring is suspended between the traction shaft and the connecting seat, and the spring is always above the horizontal shaft during the pitch stroke of the suspension seat.

[0007] The connecting seat has a shaft end and a connecting end, and is a split structure, including a seat body and a cover plate. A spring cavity is formed in the seat body, and a spring hanging column is provided near the connecting end. An arc groove is opened at the shaft end for the traction shaft to pass through and swing. The cover plate has an embedding block corresponding to the shaft end, which is embedded in the seat body. The embedding block has a shaft hole for the horizontal shaft to pass through. The surface facing the arc groove is an arc surface, and the radius of the arc surface is smaller than the radius of the arc groove.

[0008] The spring hanger of the seat has screw holes formed on it, and the cover plate has a fixing hole with a sleeve formed on it corresponding to the spring hanger. When the cover is closed, the sleeve is nested outside the spring hanger, and the fixing hole is aligned with the screw hole for the fixing screw to lock.

[0009] The base and the cover plate are fitted with a positioning pin at the overlapping point, which, together with the fixing screw, forms a fixed base and cover plate.

[0010] The springs are arranged in two or more rows, and the cover plate is formed with spring partitions corresponding to the spring gaps.

[0011] The damping structure includes a first friction plate disposed on one side of the double lugs and a second friction plate disposed on one side of the connecting seat body, which generate a damping force by static friction when the horizontal axis is tightened.

[0012] The horizontal shaft includes a shaft and an internal hexagonal fastening bolt. One end of the shaft has an internal hexagonal cap, and the other end has an internally threaded hole. The shaft passes through the double lugs of the suspension seat, the connecting seat body, and the shaft hole on the cover plate in sequence, and the fastening bolt is screwed into the end to form a rotatable positioning of the suspension seat and the connecting seat.

[0013] The shaft has an anti-rotation plane machined near the cap, and the double lugs have corresponding holes. The two work together to prevent the shaft from rotating. Disc-shaped washers are placed between the cap and the double lugs, and between the fastening bolts and the double lugs.

[0014] This utility model features a unique design, reasonable space, and high load-bearing capacity. The expansion and contraction of the spring in the structure are adapted to the weight change caused by the pitch angle of the suspension seat. The spring is stretched at a large pitch angle, and the spring force also increases. The two form a dynamic balance, and the external force required for adjustment is relatively constant, thus improving the user experience. Attached Figure Description

[0027] Reference Figures 1 to 4 The monitor suspension assembly includes a suspension seat 1, a connecting seat 2, and a horizontal shaft 3 connecting the two. A damping structure 4 is provided between the suspension seat 1 and the connecting seat 2 to achieve self-positioning.

[0028] A pair of lugs 11 are rotatably riveted to the rear of the suspension seat 1, allowing the suspension seat 1, which suspends tablet equipment such as displays, to rotate around the rivet axis relative to the lugs 11 to adjust different usage positions. The lugs 11 are clamped on both sides of the connecting seat 2 and are passed through by the horizontal shaft 3, forming a rotatable positioning to meet the adjustment of the pitch angle. Above the lugs 11 through which the horizontal shaft 3 passes, a traction shaft 12 is also provided. A spring 5 is suspended between the traction shaft 12 and the connecting seat 2. During the pitch stroke of the suspension seat 1, the spring 5 is always above the horizontal shaft 3. The spring force of the spring 5 is used to support the load on the suspension seat 1. When the suspension seat 1 is adjusted in the pitch direction, part of the load is transferred to the horizontal shaft, and the spring 5 gradually shortens and the spring force decreases relatively. Conversely, when adjusted in the pitch direction, almost all the weight is on the suspension seat. At this time, the spring 5 is stretched, and the spring force increases relatively, adapting to the load on the suspension seat 1 and achieving dynamic balance. The manual force required for adjustment also remains relatively constant.

[0029] As a preferred embodiment, the connecting seat 2 has a shaft end 21 and a connecting end 22, and is a split structure, including a seat body 23 and a cover plate 24. A spring cavity 231 is formed within the seat body 23, and a spring hanger 232 is provided near the connecting end 22. The shaft end 21 has an arcuate groove 233 for the traction shaft 12 to pass through and swing. The cover plate 24 has an insert block 241 corresponding to the shaft end, which is embedded in the seat body 23. The insert block 241 has a corresponding shaft hole for the horizontal shaft 3 to pass through. The surface facing the arcuate groove 233 is an arcuate surface 242, and the radius of the arcuate surface 242 is smaller than the radius of the arcuate groove 233. More specifically, the radius of the arcuate surface 242 is smaller than the radius of the arcuate groove 233 by the radius of a spring. The arcuate surface 242 allows the spring 5 to smoothly bend when stretched.

[0030] The spring hanger 232 of the base 23 has screw holes formed on it. The cover plate 24 has a fixing hole with a sleeve 243 formed on it corresponding to the spring hanger 232. When the cover is closed, the sleeve 243 is nested outside the spring hanger 232 and abuts the suspension end of the spring 5 to form a positioning. Figure 3 The fixing hole is aligned with the screw hole for locking with the fixing screw 6. Furthermore, a positioning pin 7 is provided at the overlap of the seat 23 and the cover plate's insert block 241, and the positioning pin 7 and the fixing screw 6 together form a fixation between the seat 23 and the cover plate 24.

[0031] The number of springs 5 ​​is configured according to the load. In this example, there are two springs 5, or more than two springs can be selected. They are all arranged side by side in the spring cavity 231. The cover plate 24 is formed with spring partitions 244 corresponding to the gaps between the springs 5 ​​to prevent the springs 5 ​​from shifting.

[0032] In this structure, the load on one side of the suspension seat 1 is mostly borne by the spring 5, while the damping structure 4 provides self-positioning. This damping structure 4 includes a first friction plate 41 located on one side of the double lugs 11 and a second friction plate 42 located on one side of the connecting seat 2 body 23. With the horizontal shaft 3 fixed, static friction generates damping force. More specifically, both the first friction plate 41 and the second friction plate 42 are provided with bent locking protrusions 411. These protrusions 411 are inserted into the pre-drilled holes in the double lugs 11 and the seat 23 respectively, forming an anti-rotation positioning. During pitch adjustment, only the relative movement of the two friction plates generates dynamic friction.

[0033] In this example, for ease of assembly, the horizontal shaft adopts the following structure: it includes a shaft 31 and an internal hexagonal bolt 32. One end of the shaft 31 has an internal hexagonal cap 311, and the other end has an internally threaded hole. The shaft 31 passes sequentially through the double lugs 11 of the suspension seat 1, the seat body 23 of the connecting seat 2, and the shaft hole on the cover plate 24, and the end is screwed into the bolt 32, forming a rotatable positioning for the suspension seat 1 and the connecting seat 2. In addition, the shaft 31 has an anti-rotation plane 312 near the cap 311, and the double lugs 11 have corresponding holes 111. With the cooperation of the two, the shaft 31 is prevented from rotating. Disc-shaped washers 33 are placed between the cap 311 and the double lugs 11, and between the bolt 32 and the double lugs 11. That is, during adjustment, the horizontal shaft 3 rotates together with the suspension seat 1 to prevent the bolt 32 from coming out. To enhance the product's appearance, a decorative cover 8 is provided on the outer side of the double ear pieces 11. The decorative cover 8 is inserted into the base 23 by means of a barbed foot 81, and a gap is left between the decorative cover 8 and the base 23 to allow the double ear pieces 11 to rotate and swing.
