Description

Technical Field

[0001] This utility model relates to the field of dynamic background wall technology, and in particular to a two-degree-of-freedom swing unit and a swing display background wall. Background Technology

[0002] Background walls, as an important component of modern architectural decoration and display, are widely used in commercial showrooms, stage design, smart homes, and other scenarios. Their function has gradually evolved from traditional static decoration to dynamic interactive installations. The dynamic display of background wall units mainly achieves the movement and transformation of the display surface through mechanically driven structures to enhance visual appeal or adapt to the needs of the scene.

[0003] However, existing dynamic background wall units still have significant limitations in terms of freedom of movement and diversity of display effects. Currently, common dynamic background wall unit display surface designs include the flip-type design in patent number CN218782757U and the telescopic design in patent number CN217885595U. The freedom of movement of these display units is generally limited to a single direction, resulting in limited three-dimensionality and making it difficult to meet the increasingly diverse decorative and functional needs of users. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a two-degree-of-freedom swing unit and a swing display background wall, which has the characteristics of simple structure and two degrees of freedom.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A two-degree-of-freedom swing unit includes a base for fixing, a first rotating assembly mounted on the front of the base, a first rotating shaft disposed on the first rotating assembly, the rotation axis of the first rotating shaft forming the x-axis, a second rotating assembly disposed in front of the first rotating assembly, a second rotating shaft disposed on the second rotating assembly, the rotation axis of the second rotating shaft forming the y-axis, and a connecting member disposed between the first rotating shaft and the second rotating shaft;

[0007] The second rotating component has a display piece installed in front of it. When the first rotating shaft rotates, it drives the second rotating component to rotate around the x-axis through the connecting piece, thereby driving the display piece to rotate around the x-axis. When the second rotating shaft rotates, it can drive the second rotating component to rotate around the y-axis, thereby driving the display piece to rotate around the y-axis.

[0008] The x-axis of the first rotating shaft is perpendicular to the y-axis of the second rotating shaft.

[0009] The first rotating assembly includes a first bracket on a base, the first rotating shaft is rotatably mounted on the first bracket, and the first rotating assembly also includes a first motor for driving the first rotating shaft to rotate.

[0010] A motor frame is installed in front of the base, the first motor is installed inside the motor frame, the first bracket is installed and fixed in front of the motor frame, and the first motor drives the first rotating shaft to rotate through a belt drive structure.

[0011] A first sensing device for monitoring the first rotating shaft is provided on one side of the first bracket. The first sensing device can control the first motor so that when it starts, it drives the first rotating shaft to rotate to the origin position.

[0012] The second rotating assembly includes a second bracket, the second rotating shaft is rotatably mounted on the second bracket, a second motor for driving the second rotating shaft to rotate is mounted on one side of the second bracket, and the exhibit is fixedly mounted on the front of the second bracket.

[0013] On the other side of the second bracket, there is a second sensing device for monitoring the second rotating shaft. The second sensing device can control the second motor so that when it starts, it drives the second rotating shaft to rotate to the origin position.

[0014] The connector includes a first sleeve rod at one end for fitting and fixing to a first rotating shaft, and a second sleeve rod at the other end for fitting and fixing to a second rotating shaft. The first sleeve rod and the second sleeve rod are connected by a connecting rod.

[0015] A swing display backdrop includes a mounting frame and a two-degree-of-freedom swing unit, wherein the base is fixed on the mounting frame so that the exhibits are arranged in an array on the mounting frame.

[0016] The beneficial effects of this utility model are:

[0017] 1. This dual-degree-of-freedom swing unit enables the exhibit to rotate around the x and y axes by setting a first rotation component and a second rotation component, that is, to swing up, down, left and right. Compared with the traditional single-direction display unit, its flexibility enhances the spatial hierarchy and visual impact of the display surface, meeting the needs of high-end art display and multi-dimensional dynamic interaction.

[0018] 2. The first and second rotating axes are independently controlled by the first and second motors, respectively, enabling the exhibit to synchronously or independently perform up-and-down swinging around the x-axis and left-and-right swinging around the y-axis, forming a composite motion trajectory in three-dimensional space, further enhancing visual appeal or adapting to scene requirements.

[0019] 3. In the first transmission assembly, the first motor drives the first rotating shaft through a belt transmission structure, which in turn drives the second transmission assembly to rotate as a whole. On the one hand, the structure is distributed in a front-to-back relationship as much as possible, making the structure more compact. When viewing the exhibit from the front, it can increase the visual proportion of the exhibit's display surface and reduce the exposure of other parts. On the other hand, it ensures the decoupling control of two degrees of freedom motion, effectively reducing the risk of mechanical interference when linked with the second transmission assembly.

[0024] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0025] Reference Figure 1 , Figure 2 This utility model proposes a two-degree-of-freedom swing unit, including a base 1 for fixing, a first rotating assembly 2 installed in front of the base 1, a first rotating shaft 24 provided on the first rotating assembly 2, the rotation axis of the first rotating shaft 24 forming the x-axis, a second rotating assembly 3 provided in front of the first rotating assembly 2, a second rotating shaft 32 provided on the second rotating assembly 3, the rotation axis of the second rotating shaft 32 forming the y-axis, and a connecting member 6 provided between the first rotating shaft 24 and the second rotating shaft 32;

[0026] The second rotating assembly 3 has a display piece 4 installed in front of it. When the first rotating shaft 24 rotates, it drives the second rotating assembly 3 to rotate around the x-axis through the connecting piece 6, which in turn drives the display piece 4 to rotate around the x-axis. When the second rotating shaft 32 rotates, it can drive the second rotating assembly 3 to rotate around the y-axis, which in turn drives the display piece 4 to rotate around the y-axis.

[0027] Furthermore, the exhibit 4 can rotate around the x and y axes through the first rotating component 2 and the second rotating component 3, that is, it can swing up, down, left and right. Compared with the traditional single-direction display unit, its flexibility enhances the spatial hierarchy and visual impact of the display surface, meeting the needs of high-end art display and multi-dimensional dynamic interaction.

[0028] Preferably, the x-axis of the first rotating shaft 24 is perpendicular to the y-axis of the second rotating shaft 32.

[0029] Reference Figure 2 The first rotating assembly 2 includes a first bracket 22 on the base 1, a first rotating shaft 24 rotatably mounted on the first bracket 22, and a first motor 21 for driving the first rotating shaft 24 to rotate.

[0030] Reference Figure 2 A motor frame 20 is installed in front of the base 1. The first motor 21 is installed inside the motor frame 20. The first bracket 22 is installed and fixed in front of the motor frame 20. The first motor 21 drives the first rotating shaft 24 to rotate through the belt drive structure 23.

[0031] A first sensing device 50 for monitoring the first rotating shaft 24 is provided on one side of the first bracket 22. The first sensing device 50 can control the first motor 21 so that when it starts, it drives the first rotating shaft 24 to rotate to the origin position. Specifically, when the first motor 21 starts, if the first sensing device 50 detects that the first rotating shaft 24 is not in the set initial position, the first motor 21 drives the first rotating shaft 24 to rotate to the initial position.

[0032] Reference Figure 2 The second rotating component 3 includes a second bracket 30, a second rotating shaft 32 is rotatably mounted on the second bracket 30, a second motor 31 for driving the second rotating shaft 32 to rotate is mounted on one side of the second bracket 30, and the exhibit 4 is mounted and fixed to the front of the second bracket 30.

[0033] On the other side of the second bracket 30, a second sensing device 51 is provided for monitoring the second rotating shaft 32. The second sensing device 51 can control the second motor 31 so that when it starts, it drives the second rotating shaft 32 to rotate to the origin position. Specifically, when the second motor 31 starts, if the second sensing device 51 detects that the second rotating shaft 32 is not in the set initial position, the second motor 31 will drive the second rotating shaft 32 to rotate to the initial position.

[0034] Specifically, the first bracket 22 is vertically fixed to the front surface of the motor frame 20, and the first rotating shaft 24 is horizontally mounted on the first bracket 22 via bearings, with its rotation axis defined as the x-axis. The output shaft of the first motor 21 is connected to the first rotating shaft 24 via a belt, driving the first rotating shaft 24 to rotate around the x-axis. The second bracket 30 is connected to the first rotating shaft 24 via a connector 6, and the second rotating shaft 32 is vertically mounted on the second bracket 30 via bearings, with its rotation axis defined as the y-axis, which is orthogonal to the x-axis. The second motor 31 is fixed to the side of the second bracket 30, and its output shaft is directly connected to the second rotating shaft 32, driving the second rotating shaft 32 to rotate around the y-axis.

[0035] Furthermore, the first rotating shaft 24 and the second rotating shaft 32 are independently controlled by the first motor 21 and the second motor 31, respectively, enabling the exhibit 4 to synchronously or independently perform up-and-down swinging around the x-axis and left-and-right swinging around the y-axis, forming a composite motion trajectory in three-dimensional space. Optionally, the exhibit 4 is a lightweight acrylic sheet or an LED display panel, fixed to the front surface of the second bracket 30 by bolts, and moves synchronously with the second bracket 30. Furthermore, when in the initial position, the display surface of the exhibit 4 faces directly forward, that is, the swing angles in all directions are zero.

[0036] Optionally, the first sensing device 50 and the second sensing device 51 are Hall sensors or photoelectric encoders, used to detect and record the rotation angle of the shaft in real time and transmit the signal to an external controller. The controller adjusts the speed and direction of the first motor 21 and the second motor 31 according to a preset program or external input signals (such as sensor signals or user commands) to realize the dynamic trajectory planning of the exhibit 4.

[0037] Reference Figure 2 The connector 6 includes a first sleeve rod 61 at one end for sleeved and fixed to the first rotating shaft 24, and a second sleeve rod 62 at the other end for sleeved and fixed to the second rotating shaft 32. The first sleeve rod 61 and the second sleeve rod 62 are connected by a connecting rod 60.

[0038] Specifically, when the first rotating shaft 24 rotates around the x-axis, it drives the second rotating assembly 3 to swing up and down around the x-axis via the connecting piece 6; when the second rotating shaft 32 rotates around the y-axis, it directly drives the second support 30 and the exhibit 4 to swing left and right around the y-axis. The movements of the two rotating shafts are independent of each other, realizing the dual-degree-of-freedom composite motion of the exhibit 4.

[0039] Reference Figure 3 A swinging display backdrop includes a mounting frame 7 and several two-degree-of-freedom swinging units. Bases 1 are mounted and fixed on the mounting frame 7, causing the exhibits 4 to be distributed in an array on the mounting frame 7. Specifically, the mounting frame 7 is a grid-like metal frame, fixed to the building wall by expansion bolts. Multiple bases 1 are arranged in a rectangular array and evenly fixed to the grid nodes of the mounting frame 7 by bolts.

[0040] Furthermore, exhibit 4 is connected to the standardized mounting frame 7 via base 1, supporting rapid horizontal and vertical arraying on walls or frames. Each unit can operate independently to present local dynamic changes, or it can form macroscopic visual effects such as overall waves and gradients through collaborative control, flexibly adapting to the decoration needs of different scales such as commercial showrooms, building curtain walls, and stage backdrops, greatly improving the product's versatility and scalability.

[0041] In summary, by organically combining a two-degree-of-freedom motion mechanism with modular design, the core problems of traditional background walls—namely, their singular dynamics, redundant structures, and low control precision—are solved. This approach enhances visual effects while achieving efficient transmission, precise control, and flexible deployment, providing an innovative technical solution for the field of dynamic background walls.
