Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0036] like Figure 1 As shown, an embodiment of the present invention provides a soundproof room for testing large display screens, including a soundproof room body 1 and a door panel 2. The soundproof room body 1 has an entrance and exit, and the door panel 2 is located at the entrance and exit for closing or opening the entrance and exit.

[0037] like Figures 1-5As shown, the soundproof room also includes a frame 3, a first drive assembly 4, a second drive assembly 5, and a conveying device 6. The frame 3 is slidably connected to the soundproof room body 1, and the door panel 2 is fixed on the frame 3. The first drive assembly 4 is located on the soundproof room body 1 and above the door panel 2, and is used to drive the frame 3 to move horizontally. Multiple second drive assemblies 5 are located on the frame 3, and are used to drive the door panel 2 to move closer to or away from the soundproof room body 1. The conveying device 6 is used to convey and support the large display screen 8. During testing, the large display screen 8 is sent into the soundproof room body 1 through the conveying device 6. The first drive assembly 4 is activated, driving the frame 3 to move smoothly, ensuring that the door panel 2 is directly facing the entrance / exit. At this time, multiple second drive assemblies 5 work synchronously to precisely close the door panel 2, forming a sealed environment, effectively isolating external noise, and ensuring the accuracy and reliability of the test data. To further improve the sealing effect, a sealing strip 20 is provided on the side of the door panel 2 facing the soundproof room body 1. When the door panel 2 is closed, the sealing strip 20 fits tightly against the soundproof room body 1, further blocking noise penetration. Meanwhile, the interior of the soundproof room is covered with sound-absorbing materials to enhance sound insulation and ensure a pure testing environment. Furthermore, the stable support of the conveyor device 6 ensures that the display screen 8 is not affected by vibration during testing, improving testing efficiency. To further enhance vibration reduction, multiple evenly distributed shock absorbers 13 are installed at the bottom of the soundproof room body 1. These shock absorbers 13 effectively absorb ground vibrations, ensuring the overall stability of the soundproof room.

[0038] like Figure 1 and Figure 2 As shown, the soundproof room also includes a ramp 7, which is located at the entrance / exit. The upper surface 70 of the ramp 7 smoothly transitions to the inner bottom surface 11 of the soundproof room body 1, allowing the conveyor 6 to smoothly enter the soundproof room body 1 from the outside. The design of the ramp 7 facilitates the smooth entry of the conveyor 6, avoids collisions and friction during the process of the conveyor 6 entering the soundproof room body 1, and ensures equipment safety.

[0039] Further reference Figure 2 and Figure 3 The soundproof chamber body 1 has a first guide groove 110 on its inner bottom surface 11, and a second guide groove 71 that smoothly transitions and connects with the first guide groove 110 on its upper surface 70. The conveying device 6 includes wheels 60, which move the large display screen 8 into the soundproof chamber body 1 sequentially along the direction of the second guide groove 71 and the first guide groove 110. Guided by the guide grooves, the wheels 60 are precisely aligned, ensuring that the large display screen 8 enters the testing position smoothly and without shaking. In addition, by setting guide grooves to accommodate the wheels 60, personnel are less likely to kick or bump into the wheels 60, reducing the risk of foot injuries and improving operational safety.

[0040] In addition, refer to Figure 3The bottom wall of the first guide groove 110 is provided with a positioning groove 111. When the conveying device 6 moves into position, the wheel 60 is located in the positioning groove 111. By setting the positioning groove 111, it is possible to ensure that the conveying device 6 accurately moves the large display screen 8 to the test position. During the test, the wheel 60 is locked in the positioning groove 111 to prevent displacement during the test, ensuring that the display screen 8 is stably positioned and improving the test accuracy. At the same time, the positioning groove 111 also facilitates the quick unlocking of the wheel 60, improving the efficiency of equipment removal and optimizing the overall test process.

[0041] When door panel 2 is closed, to prevent leakage at the junction of the first guide groove 110 and door panel 2, which would affect the sound insulation effect, refer to... Figure 5 and Figure 7 The soundproof room also includes a sealing component 9, which includes a pressing cylinder 90 and a plug 91. The pressing cylinder 90 is fixed to the door panel 2 and is used to drive the plug 91 to seal the first guide groove 110.

[0042] like Figure 1 As shown, a protective railing 12 is also installed on the outside of the soundproof room body 1. When the door panel 2 is in the open state, the door panel 2 is located inside the protective railing 12. The design of the protective railing 12 effectively prevents accidental collisions when the door panel 2 is opened, ensuring the safety of the operator.

[0043] In this embodiment, reference Figure 5 Multiple second drive components 5 are symmetrically distributed on both sides of the door panel 2 to ensure that the door panel 2 is subjected to uniform force and operates smoothly during opening and closing. (Reference) Figure 6 The second drive assembly 5 includes a drive cylinder 50 and a mounting plate 51 fixedly connected to the drive cylinder 50. The drive cylinder 50 is mounted on the frame 3, and the mounting plate 51 is fixedly connected to the door panel 2. The drive cylinder 50 is used to drive the door panel 2 to move closer to or further away from the soundproof room body 1.

[0044] To improve the stability of the front and rear movement of door panel 2, refer to Figure 4 and Figure 6 The soundproof room also includes a second sliding assembly 52, which includes a second slide rail 520 fixed to the frame 3 and a second slider 521 slidably connected to the second slide rail 520. The second slider 521 is fixedly connected to the door panel 2. Multiple sets of the second sliding assembly 52 are also provided and symmetrically distributed on both sides of the door panel 2.

[0045] like Figure 4As shown, the first drive assembly 4 includes a single-axis motion module 40 and a connecting plate 41. The single-axis motion module 40 is fixed to the soundproof room body 1 and located above the door panel 2. The connecting plate 41 is fixedly connected to the motion block 400 on the single-axis motion module 40, and the frame 3 is mated with the connecting plate 41. Specifically, the connecting plate 41 has a mating hole 410, and the top of the frame 3 is fixed with a mating post 30 that mates with the mating hole 410. The connecting plate 41 can also be fixedly connected to the frame 3 by welding or by screws to ensure structural stability.

[0046] To improve the stability of frame 3 when moving left and right, refer to Figure 4 The soundproof room also includes a first sliding component 42, which includes a first slide rail 420 fixed to the soundproof room body 1 and a first slider 421 slidably connected to the first slide rail 420. The first slide rail 420 extends horizontally, and the first slider 421 is fixedly connected to the frame 3.

[0047] The working principle is as follows: When the test is started, the first drive component 4 drives the frame 3 to move horizontally along the first slide rail 420, so that the door panel 2 is aligned with the entrance and exit of the soundproof room body 1. Then, the second drive component 5 drives the door panel 2 to move back and forth along the second slide rail 520 to achieve a seal. The downward cylinder 90 drives the plug 91 to fit tightly against the first guide groove 110 to ensure the sound insulation effect.

[0048] The beneficial effects of this utility model are as follows:

[0049] 1. Through a dual-drive design, specifically, the single-axis motion module 40 drives the connecting plate 41, causing the frame 3 to move horizontally along the first slide rail 420, ensuring the door panel 2 is precisely aligned with the entrance / exit. The first sliding component 42 ensures smooth, non-deviation-prone frame movement. The drive cylinder 50 pushes the mounting plate 51, causing the door panel 2 to move along the second slide rail 520 towards the soundproof room body 1, where the sealing strip 20 tightly adheres to the soundproof room body 1, forming a seal. The drive cylinder 50 applies vertical pressure to the door panel 2, resulting in a tighter fit between the door panel 2 and the soundproof room body 1. Furthermore, the second sliding component 52 ensures even force distribution during vertical movement of the door panel, preventing tilting and air leakage, thus providing better sealing and sound insulation.

[0050] 2. The wheels 60 of the conveying device 6 enter along the second guide groove 71 of the ramp 7 and smoothly dock with the first guide groove 110 of the bottom surface 11 of the soundproof room body 1 to avoid collision and vibration during conveying. The guide groove design also prevents people from kicking the wheels, thus improving safety.

[0051] 3. By setting the sealing component 9, when the door panel 2 is closed, the pressing cylinder 90 drives the plug 91 to insert into the first guide groove 110, blocking the gap at the junction of the first guide groove 110 and the door panel 2, preventing noise from leaking through the guide groove.

[0052] 4. By setting the positioning groove 111, the wheel 60 will automatically engage after entering the positioning groove 111. During the test, the display screen is prevented from shifting by mechanical locking. After the test, it can be quickly unlocked for easy removal.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
