Detailed Implementation

[0028] Please see Figures 1-12 This invention provides a technical solution: a bracket structure for installing multimedia equipment, including a first mounting bracket 1 and a second mounting bracket 2. The first mounting bracket 1 and the second mounting bracket 2 can be installed on a ceiling or a wall. A connecting rod 3 is rotatably connected to the first mounting bracket 1. The connecting rod 3 is provided with a mounting mechanism and a display screen 4. The mounting mechanism is used to install the display screen 4 on the connecting rod 3. The surface of the second mounting bracket 2 is provided with an adjustment mechanism. The adjustment mechanism is used to adjust the angle of the connecting rod 3 when the first mounting bracket 1 is installed on a ceiling or a wall, and also serves to support the connecting rod 3.

[0029] like Figures 1-2 In order to improve the display effect of the screen while reducing its footprint, a bracket is usually used to fix the screen to the ceiling or wall during operation. However, existing brackets usually only provide support and cannot fold the screen up. This makes the screen easy to bump and damage when moving objects or dropping things in the room. Specifically, there are two application scenarios:

[0030] Scene 1

[0031] When the device needs to be installed on the ceiling, the first mounting bracket 1 and the second mounting bracket 2 are installed on the ceiling with screws. Then, the display screen 4 is installed on the connecting rod 3 on the surface of the first mounting bracket 1 through the installation mechanism. When the display screen 4 needs to be used, the adjustment mechanism is driven to rotate the connecting rod 3 downward. When the connecting rod 3 rotates downward by 90 degrees, the display screen 4 installed on the surface of the connecting rod 3 is fully unfolded and can be used normally. After use, the adjustment mechanism is driven to rotate the connecting rod 3 upward by 90 degrees, and the display screen 4 is in a state parallel to the ceiling, which can effectively avoid being bumped. Since the connecting rod 3 is in a state parallel to the ceiling and the display screen 4 is at the end of the connecting rod 3, the connection between the first mounting bracket 1 and the connecting rod 3 is subjected to greater force. After adjusting the connecting rod 3 through the adjustment mechanism, applying a pulling force to the connecting rod 3 can effectively reduce the force on the connection between the first mounting bracket 1 and the connecting rod 3.

[0032] Scene 2

[0033] When the device needs to be installed on a wall, for easy viewing, the display screen 4 is usually adjusted to a 45-degree angle with the wall. The first mounting bracket 1 and the second mounting bracket 2 are installed on the wall with screws, and then the display screen 4 is installed on the connecting rod 3 by the mounting mechanism. When the display screen 4 is needed, the adjustment mechanism is activated, which adjusts the connecting rod 3 to start rotating relative to the first mounting bracket 1. When the connecting rod 3 rotates to 45 degrees, the angle between the display screen 4 on the surface of the connecting rod 3 and the wall is exactly 45 degrees. Since the display screen 4 is on the other side of the connecting rod 3 at this time, the force at the connection between the first mounting bracket 1 and the connecting rod 3 is relatively large. After adjusting the angle of the connecting rod 3, the adjustment mechanism can also support the connecting rod 3, which can effectively reduce the force at the connection between the first mounting bracket 1 and the connecting rod 3. When the display screen 4 is finished using, the adjustment mechanism is activated, which will drive the connecting rod 3 and the display screen 4 to reset.

[0034] The device has a simple structure and can be used in two environments: ceiling and wall. It can also unfold and retract the display screen 4, effectively preventing damage to the display screen 4.

[0035] like Figure 2 , Figures 7-9As a further embodiment of the present invention, the adjusting mechanism includes two first sliders 5; a first groove 6 is provided on the second mounting bracket 2, the two first sliders 5 are symmetrically distributed in the first groove 6 and both first sliders 5 are slidably connected to the first groove 6; a second groove 7 is provided on the surface of the connecting rod 3, a second slider 8 is slidably connected in the second groove 7, two first connecting blocks 10 are rotatably connected to the second slider 8, the other ends of the two first connecting blocks 10 are rotatably connected to a first connecting rod 9, the other ends of the first connecting rod 9 are rotatably connected to a third connecting block 12, a second connecting block 11 is rotatably connected to the third connecting block 12, and the second connecting block 11 is rotatably connected to the first slider 5; the second mounting bracket 2 is provided with a drive The driving mechanism is used to drive the two first sliders 5 to slide. A limiting mechanism is provided between the first mounting bracket 1 and the second mounting bracket 2. The limiting mechanism is used to adjust the position of the second slider 8 according to the position of the two first sliders 5 when the driving mechanism adjusts the position of the two first sliders 5. During operation, when the two first sliders 5 are driven to move closer to each other in the first slide groove 6, the first connecting rod 9 can rotate freely at its two ends under the action of the first connecting block 10, the second connecting block 11 and the third connecting block 12. When the two first sliders 5 move closer to each other, the connecting rod 3 starts to rotate relative to the first mounting bracket 1 under the action of the two first connecting rods 9 and the second slider 8.

[0036] like Figure 7 As shown, as a further embodiment of the present invention, the driving mechanism includes a bidirectional threaded rod 13 with self-locking properties. The bidirectional threaded rod 13 is located in the first slide groove 6, and both ends of the bidirectional threaded rod 13 are rotatably connected to the second mounting bracket 2. A first motor 14 is fixedly connected to the right side surface of the second mounting bracket 2, and the left end of the output shaft of the first motor 14 is fixedly connected to the right end of the bidirectional threaded rod 13. Two first sliders 5 are threadedly engaged with the transmission parts in two directions on the surface of the bidirectional threaded rod 13. A sliding mechanism is provided on the surface of the first mounting bracket 1. The sliding mechanism is used to adjust the position of the second slider 8 according to the position of the two first sliders 5 when the bidirectional threaded rod 13 rotates to adjust the position of the two first sliders 5. During operation, when it is necessary to drive the two first sliders 5 in the first slide groove 6 to slide, the first motor 14 is started. The first motor 14 will drive the bidirectional threaded rod 13 in the first slide groove 6 to rotate. When the bidirectional threaded rod 13 rotates, it will drive the first sliders 5 on the left and right sides to move simultaneously to positions away from or close to each other.

[0037] like Figure 3 , Figures 6-9As shown, as a further embodiment of the present invention, the limiting mechanism includes a first hydraulic cylinder 15, which is located within the second slide groove 7 and is fixedly connected to the connecting rod 3; a second hydraulic cylinder 16 is fixedly connected to the first mounting bracket 1, and the oil chambers of the first hydraulic cylinder 15 and the second hydraulic cylinder 16 are in communication; a spring 23 is sleeved on the telescopic end of the second hydraulic cylinder 16, one end of the spring 23 is fixedly connected to the second hydraulic cylinder 16 and the other end is fixedly connected to the telescopic end of the second hydraulic cylinder 16; two second connecting rods 24 are fixedly connected to the telescopic end of the second hydraulic cylinder 16, and the other ends of the two second connecting rods 24 on the left and right sides are rotatably connected to a third slider 25, which is slidably connected to the first slide groove 6; the left side of the first slider 5 and the right side of the first slider 5 are also fixedly connected to the first slide groove 6. Each slider 5 has a fourth slider 26 on its right side, which is slidably connected to the first slide groove 6. The bottom of the first mounting bracket 1 has two fixing rods 27. The front fixing rod 27 is simultaneously fixedly connected to the left third slider 25 and the right fourth slider 26, and the rear fixing rod 27 is simultaneously fixedly connected to the left fourth slider 26 and the right third slider 25. During operation, when the left and right first sliders 5 move closer together, the spring 23 applies a backward force to the extension end of the second hydraulic cylinder 16. The second hydraulic cylinder 16 then applies forces to the left and right first sliders 5 respectively through the two second connecting rods 24. When the left and right first sliders 5 move closer together, the fourth sliders 26 on the left and right sides... Block 26 will slide along with the first slider 5, causing the third sliders 25 on both sides to move away from each other. The extension end of the second hydraulic cylinder 16 will move backward under the action of the spring 23, drawing hydraulic oil into its interior. This causes the extension end of the first hydraulic cylinder 15 to retract and move the second slider 8. As the first sliders 5 on both sides gradually move closer to each other, the second slider 8 simultaneously moves closer to the display screen 4, ensuring that the second slider 8 is always positioned directly below the second mounting bracket 2. The first sliders 5 on both sides move downward relative to the second mounting bracket 2 through the first connecting rods 9 on both sides. When the second slider 8 moves downward... This will cause the connecting rod 3 to rotate downwards; when the connecting rod 3 rotates downwards by 45 degrees, the first slider 5 moves to simultaneously engage with the third slider 25 and the fourth slider 26. As the first slider 5 continues to move, the first sliders 5 on the left and right sides will push the third sliders 25 on the left and right sides to move closer to each other. At this time, the third sliders 25 on the left and right sides will drive the extension end of the second hydraulic cylinder 16 to move forward through the second connecting rod 24. The hydraulic oil in the second hydraulic cylinder 16 will be pushed into the first hydraulic cylinder 15. The extension end of the first hydraulic cylinder 15 will then begin to extend and drive the second slider 8 to move. As the second slider 8 begins to move and the first sliders 5 on the left and right sides get closer and closer, the connecting rod 3 will continue to rotate downwards.When the first sliders 5 on both sides move to their closest positions, the connecting rod 3 rotates downwards to a 90-degree position, and the display screen 4 is in the open state. When it needs to be retracted, the first motor 14 is started to drive the bidirectional threaded rod 13 to rotate in the opposite direction. When the first mounting bracket 1 and the second mounting bracket 2 are installed on the wall and the display screen 4 needs to be unfolded, the first motor 14 is started to drive the connecting rod 3 to rotate relative to the first mounting bracket 1. When the connecting rod 3 rotates relative to the first mounting bracket 1 to a 45-degree angle, the display screen 4 is fully unfolded, and the first motor 14 is stopped. At this time, the first connecting rod 9 at the bottom position supports the second slider 8, and the first connecting rod 9 at the top pulls on the second slider 8, thereby further improving the stability of the first connecting rod 3.

[0038] like Figure 4 As shown, as a further embodiment of the present invention, the mounting mechanism includes a sliding frame 28, which is fixedly connected to the display screen 4 and slidably connected to the connecting rod 3. A second motor 29 is fixedly connected to the rear of the surface of the connecting rod 3. The second motor 29 is provided with a lead screw structure, which is used to drive the sliding frame 28. During operation, the position of the display screen 4 on the connecting rod 3 can be adjusted according to the size of the installed display screen 4. This can drive the second motor 29 to rotate, which in turn drives the lead screw structure to run. When the lead screw structure runs, it drives the sliding frame 28 to slide on the surface of the connecting rod 3, thereby causing the display screen 4 to move relative to the connecting rod 3.

[0039] like Figures 4-5 As a further embodiment of the present invention, wire clamping rings 31 are fixedly connected to the upper surface of the first mounting bracket 1, the surface of the connecting rod 3, and the surface of the sliding bracket 28. The three wire clamping rings 31 are used to fix the wires of the display screen 4 to the surfaces of the first mounting bracket 1, the connecting rod 3, and the sliding bracket 28. The wire clamping rings 31 on the surface of the connecting rod 3 and the surface of the sliding bracket 28 are both located on the right side, and the wire clamping rings 31 on the surface of the connecting rod 3 are located on the surface of the connecting rod 3 close to the first mounting bracket 1. During operation, the three wire clamping rings 31 can fix the wires of the display screen 4, thereby avoiding the wires from getting tangled when the display screen 4 is unfolded and retracted.
