Description

Technical Field:

[0001] The utility model belongs to the technical field of mechanical support, and particularly relates to a display bracket suspension assembly. Background Art:

[0002] The bracket used to hang a display involves multi-point damping positioning to meet the convenient adjustment of the display and enable it to hover at any position and angle. Therefore, a multi-axis design is a basic requirement, and a damped solution is adopted to achieve the requirement of stopping without external force. For example:

[0003] CN202220429674.3 discloses a display bracket adapter assembly, including a connecting plate for locking the display, a pitching rotating shaft, and a hinge seat. The connecting plate is rotatably positioned on the hinge seat through the pitching rotating shaft. Among them: the hinge seat has a through shaft cavity, a fan-shaped hole communicating with the center of the shaft cavity, and a shaft connecting position connected to the bracket; threaded holes are processed at the axial center positions at both ends of the pitching rotating shaft, and a shaft hole is processed in the middle. The axial center lines of the shaft hole and the threaded holes are perpendicular to each other, and the threaded holes penetrate through the shaft hole; the pitching rotating shaft passes through and is rotatably positioned in the shaft cavity of the hinge seat, and a torsion spring and a damping adjustment screw are arranged between the two; the fixed shaft extending from the back of the connecting plate passes through the fan-shaped hole, and the end is inserted into the shaft hole of the pitching rotating shaft and is constrained therein by the positioning set screws screwed in from both ends of the pitching rotating shaft. In addition to using the torsion spring force to provide basic load-bearing, this solution is also equipped with damping gaskets to generate adjustable damping force on the pitching rotating shaft to meet the needs of hanging different specifications of displays. However, due to the constraint of the caliber of the pitching rotating shaft, the damping force arm is relatively short, and it is difficult to generate a large damping force.

[0004] How to provide a more reasonable technical solution has become the object of research of the present invention. Summary of the Invention:

[0005] The purpose of the utility model is to design a display bracket suspension assembly with an adjustment bolt arranged outside the pitching rotating shaft to increase the damping force adjustment.

[0006] The technical solution of the utility model is realized as follows: A display bracket suspension assembly includes a connecting plate assembly for hanging a display, a pitching rotating shaft, and a hinge seat. The connecting plate assembly is rotatably positioned on the hinge seat through the pitching rotating shaft. Its characteristics are: the connecting piece arranged backward by the connecting plate assembly forms a surface fit with the hinge seat, and outside the pitching rotating shaft passing through the two, an adjustment bolt is also arranged in parallel, and the adjustment of the surface contact damping force is formed by the adjustment bolt.

[0007] The connecting piece and the hinge seat form a nested double-sided clamping fit. Both are provided with a shaft hole for the pitch rotating shaft to pass through and a bolt hole for the adjusting bolt to pass through. The bolt hole on one of them is an arc-shaped groove, and the arc-shaped groove is centered on the shaft hole. At least in the outer edge area of the arc-shaped groove, a damping gasket is provided on the contact surface between the connecting piece and the hinge seat, and the damping force is adjusted by the passing adjusting bolt.

[0008] The connecting piece and the hinge seat form a nested double-sided clamping fit, and there are the following three structures: First, a groove is machined in the middle of the hinge seat, and a shaft hole and a bolt hole penetrate through it. The connecting piece is a flat body with parallel double sides, which can be movably embedded in the groove, and is provided with a shaft hole and an arc-shaped groove corresponding to the bolt hole on the hinge seat. Second, the connecting piece is a channel-shaped sheet metal part, which is sleeved on the hinge seat with parallel surfaces processed on both sides. A shaft hole and a bolt hole penetrate through the hinge seat, and a shaft hole and an arc-shaped groove corresponding to the bolt hole on the hinge seat penetrate through the connecting piece. Third, the connecting piece is a channel-shaped sheet metal part, which is sleeved on the hinge seat with parallel surfaces processed on both sides. A shaft hole and a bolt hole penetrate through the connecting piece, and a shaft hole and an arc-shaped groove corresponding to the bolt hole on the connecting piece penetrate through the hinge seat.

[0009] The diameter of the bolt hole of the hinge seat is equivalent to the diameter of the damping gasket arranged outside the arc-shaped groove of the connecting piece, and a movable embedded cap is configured in the bolt hole. The adjusting bolt penetrates through the two movable embedded caps at the same time and generates fastening by abutting against the movable embedded caps.

[0010] The connecting plate assembly includes a connecting piece, a suspension plate and a load-bearing rivet. A bearing recess for accommodating the rivet head is machined in the center of the front end of the connecting piece, and the load-bearing rivet head is clamped between the two by means of a configured intermediate rotating piece. The intermediate rotating piece and the outer edge of the connecting piece are riveted by several small rivets, and the deformed end of the load-bearing rivet passes through the middle hole of the suspension plate and is riveted. Gaskets are provided on both the front and back surfaces of the suspension plate, allowing the suspension plate to make rotational adjustment relative to the connecting piece.

[0011] The connecting plate assembly includes a connecting piece, a suspension plate and a load-bearing rivet. The contact surface center between the channel-shaped sheet metal connecting piece and the suspension plate is directly riveted by the load-bearing rivet. Gaskets are provided on both the front and back surfaces of the suspension plate, allowing the suspension plate to make rotational adjustment relative to the connecting piece.

[0012] The hinge seat is a beryllium aluminum processed part, having a double semi-circular staggered structure with one large and one small. A shaft hole, a bolt hole or an arc-shaped groove is provided on the small semi-circular part, and a bifurcated shaft seat capable of being hinged with the cantilever seat extends backward from the large semi-circular part.

[0013] The small semi-circular part of the hinge seat is processed forward with an upper inclined surface and a lower inclined surface with the shaft hole end as the included angle, and upper convex points and lower convex points are correspondingly processed at the ends of the upper inclined surface and the lower inclined surface. When the pitch adjustment reaches the limit position, they can respectively abut against the back of the suspension plate in the connecting plate assembly.

[0014] The articulated seat extends an arc-shaped spring groove above the arc-shaped groove, and a spring is placed in the arc-shaped spring groove, with one end of the spring abutting against the adjusting bolt.

[0040] Refer to Figures 1 to 6 , the monitor bracket suspension assembly includes a connecting plate assembly 1, a hinge seat 2 and a pitching rotating shaft 3; the connecting plate assembly 1 is rotatably positioned on the hinge seat 2 through the pitching rotating shaft 3. The connecting plate assembly 1 includes a suspension plate 11 that can be used to suspend a monitor etc. forward and a connecting member 12 that can be hinged to the hinge seat 2 backward. The connecting member 12 forms a surface fit with the hinge seat 2. Outside the pitching rotating shaft 3 passing through both of them, an adjusting bolt 4 is also arranged in parallel, and the adjusting bolt 4 forms the adjustment of the surface contact damping force.

[0041] More specifically, the connecting member 12 and the hinge seat 2 form a nested double-sided clamping fit. Both of them are provided with a shaft hole 5 for the pitching rotating shaft to pass through and a bolt hole 6 for the adjusting bolt to pass through. The bolt hole on one of them is an arc groove 61, and the arc groove 61 takes the shaft hole 5 as the center. The arc groove 61 provides the stroke for pitching adjustment; at least in the outer edge area of the arc groove 61, a damping gasket 7 is arranged on the contact surface between the connecting member 12 and the hinge seat 2, and the damping force is adjusted by the passing adjusting bolt 4. The surface fit structure between the connecting member and the hinge seat has the following three structures:

[0042] One, the connecting member 12 is movably clamped by the hinge seat 2, and the arc groove 61 is opened on one side of the connecting member:

[0043] Refer to Figure 1 , Figure 2 and Figure 3, the connecting member 12 and the hinge seat 2 form a double-sided clamping fit. An embedding groove 21 is machined in the middle of the hinge seat 2, and a shaft hole 5 and a bolt hole 6 penetrate through it. The connecting member 12 is a flat body with two parallel sides, which can be movably embedded in the embedding groove 21, and is provided with a corresponding shaft hole 5 and an arc-shaped groove 61 corresponding to the bolt hole 6 on the hinge seat. The arc-shaped groove 61 is centered on the shaft hole 5. The adjusting bolt 4 passes through the bolt hole 6 of the hinge seat and the arc-shaped groove 61 of the connecting member, and damping gaskets 7 are arranged on both sides of the arc-shaped groove 61, and are fastened on the damping gaskets 7 by the passing adjusting bolt 4. That is, by tightening or loosening the adjusting bolt 4, the massage force, that is, the damping force, sliding over the surface of the damping gasket 7 can be adjusted.

[0044] Further, the diameter of the bolt hole 6 of the hinge seat is equivalent to the diameter of the damping gasket 7 arranged outside the arc-shaped groove of the connecting member, and a movable embedded cap 27 is arranged in the bolt hole 6. The adjusting bolt 4 passes through both movable embedded caps 27 at the same time and abuts against the movable embedded caps 27 to produce fastening. The movable embedded cap 27 is used to increase the contact surface. Of course, ordinary gaskets can also be used. The movable embedded cap 27 can also eliminate the extra clearance generated by the rotation adjustment of the adjusting bolt. In addition, in this example, the damping gasket 7 adopts an arc-shaped structure similar to the shape of the outer edge of the arc-shaped groove and is embedded on one side of the connecting member 12. During adjustment, the movable embedded cap 27 or the gasket can slide on the surface of the damping gasket 7 to generate a damping force. The actual effect is similar to that of a circular damping gasket, but only the worn object is different. In this example, the worn object is the movable embedded cap 27. If it is a circular damping gasket, the worn object is the surface of the connecting member 12. It can be seen that this example is more reasonable.

[0045] In this example, the connecting plate assembly 1 includes a suspension plate 11, a connecting member 12 and a load-bearing rivet 14. A bearing recess capable of accommodating the rivet head is machined in the center of the front end of the connecting member 12, and the load-bearing rivet head is clamped between the two by means of an intermediate rotating piece 15 arranged. The intermediate rotating piece 15 and the outer edge of the connecting member 12 are riveted by several small rivets 16, and the deformed end of the load-bearing rivet 14 passes through the middle hole of the suspension plate 11 and is riveted. Gaskets 13 are arranged on both the front and rear surfaces of the suspension plate 11, allowing the suspension plate 11 to rotate and adjust relative to the connecting member 12. Generally, the small gasket 13 here also adopts a damping type and can automatically stop at the adjusted position.

[0046] II. The hinge seat 2 is movably clamped by the connecting member 12, and the arc-shaped groove 61 is opened on one side of the connecting member:

[0047] Refer to Figure 4 , Figure 5 and Figure 6, the connecting member 12 and the hinge seat 2 form a double-sided clamping fit. The connecting member 12 is a channel-shaped sheet metal part that is wrapped around the hinge seat 2 with parallel surfaces processed on both sides. The hinge seat 2 is penetrated with a shaft hole 5 and a bolt hole 6, and the connecting member 12 is penetrated with a shaft hole 5 and an arc-shaped groove 61 corresponding to the bolt hole on the hinge seat. In this example, the damping gasket 7 is embedded on the side of the hinge seat 2 to increase the friction area with the inner surface of the connecting member 12. In addition, by adjusting the adjusting bolt 4 fixed outside the connecting member 12, friction can also be formed with the outer surface of the connecting member 12, greatly increasing the damping force.

[0048] In this example, the connecting plate assembly 1 includes a suspension plate 11, a connecting member 12, and a load-bearing rivet 14; the connecting plate 12 of the channel-shaped sheet metal part is directly riveted to the center of the contact surface with the suspension plate 11 through the load-bearing rivet 14; gaskets 13 are provided on both the front and rear surfaces of the suspension plate 11, allowing the suspension plate 11 to rotate and adjust relative to the connecting member 12. In addition, for decoration, a decorative cover 17 that is semi-formed and can be buckled with each other can be configured outside the connecting member 12 to cover the exposed parts of the pitching rotating shaft 3 and the adjusting bolt 4, such as Figures 4 to 6 , and it is also applicable to other solutions.

[0049] III. The hinge seat 2 is movably clamped by the connecting member 12, and the arc-shaped groove 61 is opened on one side of the hinge seat:

[0050] Refer to Figure 8 and Figure 10 , the connecting member 12 is a channel-shaped sheet metal part that is wrapped around the hinge seat 2 with parallel surfaces processed on both sides. The connecting member 12 is penetrated with a shaft hole 5 and a bolt hole 6, and the hinge seat 2 is penetrated with a shaft hole 5 and an arc-shaped groove 61 corresponding to the bolt hole on the connecting member. Similarly, the damping gasket 7 is embedded on the side of the hinge seat 2. In this figure, the adjusting bolt 4 rotates synchronously with the connecting member 12, and friction is generated according to the contact between the inner surface of the connecting member 12 and the damping gasket 7.

[0051] Furthermore, in the above structure, the hinge seats 2 involved are all aluminum processing parts, such as Figure 2 , Figure 3 , Figure 5 , Figure 8 and Figure 10 , which has a double semi-circular staggered structure of one large and one small. The shaft hole 5, the bolt hole 6 or the arc-shaped groove 61 are opened on the small semi-circular part 22, and the large semi-circular part 23 extends backward with a bifurcated shaft seat 24 that can be hinged with the cantilever seat. That is to say, with the help of the bifurcated shaft seat 24, it can swing left and right relative to the cantilever seat.

[0052] In addition, an upper inclined surface 25 and a lower inclined surface 26 with an included angle at the shaft hole end can be processed forward on the small semi-circular part 22 of the hinge seat, and upper convex points 251 and lower convex points 261 are respectively processed at the ends of the upper inclined surface 25 and the lower inclined surface 26. When the pitching is adjusted to the designed limit position, the two can respectively abut against the back of the suspension plate 11 in the connecting plate assembly, such asFigures 4 to 10 . However, in the example of Figures 1 to 3 , the central angle of the groove 21 on the hinge seat is used as the limit position for pitch adjustment design, and in cooperation with the circular outer edge at the front end of the connecting member 12, the constraint of the limit position can also be achieved.

[0053] In order to improve the suspension bearing capacity, a torsion spring or a spring is also arranged between the hinge seat 2 and the connecting member 12 for preloading. The structure is as follows:

[0054] 1. As shown in Figure 7 and Figure 8 , a groove 21 is machined in the middle of the hinge seat 2, and a torsion spring 8 is placed in the groove 21. The torsion spring 8 is passed through by the pitch rotation shaft 3, with one end abutted against the hinge seat 2 and the other end abutted against the adjusting bolt 4, blocking the adjusting bolt 4 from moving upward along the arc-shaped groove. That is, initially, one side of the suspension plate 11 can bear the weight corresponding to the torsion spring force.

[0055] 2. As shown in Figure 9 and Figure 10 , the hinge seat 2 extends an arc-shaped spring groove 62 above the arc-shaped groove 61, and a spring 9 is placed in the arc-shaped spring groove 62. One end of the spring 9 abuts against the adjusting bolt 4, and the other end is constrained within the arc-shaped spring groove 62. The working principle is the same as that of the torsion spring. In this structure, a spring 9 can be arranged on each side of the hinge seat 2 to increase the initial load-bearing capacity.
