Description

Technical Field

[0001] This utility model relates to the field of soundproof enclosure technology, and in particular to an enclosure with a double-layer soundproof structure. Background Technology

[0002] The double-layer sound insulation structure is a composite structure that achieves acoustic noise reduction by superimposing two layers of materials. It can reduce airborne noise and impact noise through the dual effects of reflecting and absorbing sound waves, thereby improving the sound insulation effect. A chassis with a double-layer sound insulation structure is a protective shell suitable for precision equipment. It consists of an outer metal layer, a high-strength plastic layer, an inner sound insulation cotton layer, a damping plate, and an intermediate air layer. Some models include sealing strips to enhance sound insulation. The double-layer structure can reflect and absorb the noise of equipment operation, weaken vibration transmission, and also take into account the dustproof design of the heat dissipation holes.

[0003] The primary function of a traditional computer case is to provide standardized mounting positions and a fixed structure for the CPU, motherboard, graphics card, hard drive, power supply, and other core hardware, ensuring stable hardware connections and preventing displacement or poor contact. This is fundamental for the normal operation of a computer. Existing technology used sound-absorbing materials for sound insulation, attaching sound-absorbing cotton and sound-insulating foam materials inside the case. These materials absorb and dissipate sound energy, reducing noise propagation and reverberation. However, the sound absorption effect of these materials is limited. While sound-absorbing cotton and sound-insulating foam are effective at absorbing high-frequency noise, they are less effective at absorbing low-frequency noise generated by the computer case. Current technology employs a double-layer sound insulation structure consisting of two walls and an air layer in between. When sound waves are incident on this structure, they undergo multiple reflections between the two walls and the air layer, effectively blocking vibrations from the power supply and graphics card that are transmitted to the casing. However, the double-layer sound insulation structure has complex disassembly steps, requiring a specific disassembly sequence, which lengthens the overall disassembly time. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a chassis with a double-layer sound insulation structure, aiming to improve the problem that the disassembly steps of the double-layer sound insulation structure in the prior art are complicated, require operation in a specific order, and lengthen the disassembly time of the entire chassis.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a chassis with a double-layer sound insulation structure, including a chassis shell, a quick-opening mechanism installed on the right side of the chassis shell for quickly opening the rear door, and a quick-changing mechanism slidably connected inside the chassis shell for quickly replacing the sound insulation material; the quick-opening mechanism includes a rotating door, with the left sides of multiple rotating doors installed on the right side of the chassis shell, and rotating shafts fixedly connected to opposite sides of the multiple rotating doors, with rotating bevel gears fixedly connected to the top of each rotating shaft, and a drive assembly installed on the top of each rotating bevel gear.

[0006] As a further description of the above technical solution: The drive assembly includes a motor, the outer wall of which is fixedly connected to the inside of the chassis shell. A driving bevel gear is fixedly connected to the output end of the motor. A driven bevel gear is meshed with the right side of the driving bevel gear. A transmission rod is fixedly connected to the middle of the driven bevel gear. Fixed bevel gears are fixedly connected to both the front and rear ends of the transmission rod. The bottom of the fixed bevel gear is meshed with the top of the rotating bevel gear.

[0007] As a further description of the above technical solution: The quick-change mechanism includes multiple sliding blocks, all of which are fixedly connected to the inside of the chassis shell. Each of the multiple sliding blocks is slidably connected to a frame shell on an adjacent side. A front cover is rotatably connected to the bottom right side of each frame shell, and a locking component is installed on the top of the front cover.

[0008] As a further description of the above technical solution: The locking assembly includes a rotating column that is slidably connected inside the front cover. A limit ring is fixedly connected to the outer wall of the rotating column, and a locking head is fixedly connected to the left side of the outer wall of the rotating column.

[0009] As a further description of the above technical solution: A sound insulation plate is slidably connected inside the outer frame, and the left side of the front cover is slidably connected to the other side of the sound insulation plate.

[0010] As a further description of the above technical solution: The left side of the chassis shell is rotatably connected to a chassis door, and the left side of the chassis door has a pull groove.

[0011] As a further description of the above technical solution: A support plate is fixedly connected to the bottom of the chassis shell, and casters are fixedly connected to the bottom of the support plate near the four corners.

[0012] As a further description of the above technical solution: A handle is installed on the top of the chassis shell, and a bolt is threaded to the bottom of the handle.

[0013] This utility model has the following beneficial effects: 1. In this utility model, after the motor starts, it drives the drive assembly to rotate the rotating bevel gear and the rotating shaft fixed to the rotating bevel gear, thereby driving the rotating door to open. By taking advantage of the forward and reverse rotation of the motor and its fixedness, the problems of complicated disassembly steps and long disassembly time of the double-layer sound insulation structure are solved.

[0014] 2. In this utility model, when installing or replacing the sound insulation panel after the quick-opening mechanism is opened, first pull out the frame shell and front cover fixed by the locking component from the sliding block, then rotate the rotating column of the locking component. After the locking component is disengaged, the bottom of the front cover is disengaged from the frame shell. After replacing the new sound insulation panel, reverse the operation to quickly complete the replacement and installation of the sound insulation panel. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 3 and Figure 4This utility model provides an embodiment of a chassis with a double-layer sound insulation structure, including a chassis shell 1. A quick-opening mechanism 2 is installed on the right side of the chassis shell 1 for quickly opening the rear door. A quick-changing mechanism 3 is slidably connected inside the chassis shell 1 for quickly replacing the sound insulation material. The quick-opening mechanism 2 includes rotating doors 201. Multiple rotating doors 201 are installed on the left side of the chassis shell 1. Rotating shafts 202 are fixedly connected to the rotating doors 201 on opposite sides. Rotating bevel gears 203 are fixedly connected to the top of each rotating shaft 202. A drive assembly 204 is installed on the top of each rotating bevel gear 203. The drive assembly 204 includes a motor 2041. An asynchronous motor 2041 is used. Its working principle is to generate a rotating magnetic field by passing three-phase alternating current through the stator winding, which cuts the magnetic field and forms an electromagnetic torque, driving the rotor to rotate with the magnetic field. It is mainly composed of a stator, rotor, air gap and auxiliary components. The outer wall of the motor 2041 is fixedly connected to the inside of the casing 1. The output end of the motor 2041 is fixedly connected to a driving bevel gear 2042. The right side of the driving bevel gear 2042 is meshed with a driven bevel gear 2043. The middle part of the driven bevel gear 2043 is fixedly connected to a transmission rod 2044. The front and rear ends of the transmission rod 2044 are fixedly connected to fixed bevel gears 2045. The bottom of the fixed bevel gear 2045 is meshed with the top of the rotating bevel gear 203. Specifically, when the motor 2041 starts, it drives the active bevel gear 2042 to rotate. Since the active bevel gear 2042 meshes with the driven bevel gear 2043, the driven bevel gear 2043 will rotate accordingly, thereby driving the transmission rod 2044 and the fixed bevel gear 2045 fixed at both ends to rotate synchronously. When the transmission rod 2044 and the fixed bevel gear 2045 rotate clockwise, they will drive the rotating bevel gear 203 meshing on the front side to rotate clockwise, and at the same time drive the rotating bevel gear 203 meshing on the rear side to rotate counterclockwise. As the rotating bevel gears 203 on the front and rear sides rotate in opposite directions, the rotating shaft 202 fixedly connected to it will rotate synchronously, thereby driving the rotating door 201 to open. Through the forward and reverse rotation control of the motor 2041, the opening and closing operation of the rotating door 201 can be realized, and the fixed installation of the motor 2041 ensures the stability of the transmission. This structural design replaces the traditional manual disassembly method and effectively solves the problem of complicated disassembly steps of the double-layer sound insulation structure, which leads to excessive disassembly time of the overall chassis.

[0019] Reference Figure 5 , Figure 6 and Figure 7The quick-change mechanism 3 includes multiple sliding blocks 301, which are all fixedly connected to the inside of the chassis shell 1. The multiple sliding blocks 301 are slidably connected to the frame shell 302 on their adjacent sides. The bottom right side of the frame shell 302 is rotatably connected to the front cover 303. The top of the front cover 303 is equipped with a locking component 304. The locking component 304 includes a rotating column 3041, which is slidably connected to the inside of the front cover 303. The outer wall of the rotating column 3041 is fixedly connected to a limit ring 3042. The left side of the outer wall of the rotating column 3041 is fixedly connected to a locking head 3043. The inside of the frame shell 302 is slidably connected to a sound insulation plate 4. The other side of the sound insulation plate 4 is slidably connected to the left side of the front cover 303. Specifically, when the quick-opening mechanism 2 is opened, and the sound insulation panel 4 is installed or replaced, first, the frame housing 302 and the front cover 303, which are fixed by the locking assembly 304, are pulled out as a whole from the slide block 301. Then, the rotating column 3041 of the locking assembly 304 is rotated, causing the locking head 3043, which is fixed to the rotating column 3041, to rotate inside the frame housing 302 to a position opposite to the notch direction. Then, the rotating column 3041 is pulled out. At this time, due to the limiting effect of the limiting ring 3042, the entire locking assembly 304 will not be pulled out from the front cover 301. 03. Once the locking component 304 disengages from the frame housing 302, the connection between the bottom of the front cover 303 and the frame housing 302 is released, allowing the old sound insulation panel 4 to be removed and replaced with a new one. After replacement, follow the reverse steps: insert the rotating column 3041 back in, rotate it to make the locking head 3043 engage with the notch in the frame housing 302, and then push the frame housing 302 and the front cover 303 together into the sliding block 301 to complete the fixation. This set of operating procedures simplifies the locking and disassembly steps, enabling the rapid replacement and installation of the sound insulation panel 4.

[0020] Reference Figure 1 , Figure 2 and Figure 5 The left side of the chassis shell 1 is rotatably connected to the chassis door 7. The left side of the chassis door 7 is provided with a pull groove 8. The bottom of the chassis shell 1 is fixedly connected to the support plate 9. The bottom of the support plate 9 is fixedly connected to the universal wheels 10 near the four corners. The top of the chassis shell 1 is equipped with a handle 11. The bottom of the handle 11 is threaded with a bolt 12. Specifically, the chassis door 7 of the chassis shell 1 is provided with a pull groove 8, which can be easily applied through the pull groove 8 to help open the chassis door 7 quickly, improving the ease of opening the chassis. The bottom of the chassis shell 1 is fixed with a support plate 9, and the casters 10 installed under the support plate 9 provide convenience for the overall movement of the chassis. In conjunction with the handle 11 fixed to the chassis shell 1 by bolts 12, the entire chassis can be moved by pushing and pulling with the help of the handle 11, solving the problem of difficult movement of heavy chassis and making the position adjustment of the chassis more flexible and labor-saving.

[0021] Working principle: As the motor 2041 starts, it rotates the driving bevel gear 2042. With the rotation of the driving bevel gear 2042, the driven bevel gear 2043 meshing with it drives the transmission rod 2044 and the fixed bevel gear 2045 fixed at both ends of the transmission rod 2044 to rotate. As the transmission rod 2044 and the fixed bevel gear 2045 rotate clockwise, they drive the rotating bevel gear 203 meshing on the front side to rotate clockwise, and drive the rotating bevel gear 203 meshing on the rear side to rotate counterclockwise. With the rotation of the rotating bevel gears 203 on the front and rear sides, the rotating shaft 202 fixed with the rotating bevel gear 203 drives the rotating door 201 to open. With the forward and reverse rotation of the motor 2041 and the fixation of the motor 2041, the problem of complicated disassembly steps of the double-layer sound insulation structure and long disassembly time of the overall chassis is solved. With the opening of the quick-opening mechanism 2, when installing or replacing the sound insulation panel 4, the frame housing 302 and the front cover 303, which are fixed by the locking assembly 304, are pulled out from the slide block 301. Then, the rotating column 3041 of the locking assembly 304 is rotated, so that the locking head 3043, which is fixed to the rotating column 3041, rotates inside the frame housing 302 to the opposite direction of the notch. Then, the rotating column 3041 is pulled out. Under the limit of the limiting ring 3042, the entire locking assembly 304 will not be pulled out from the front cover 303. As the locking assembly 304 is disengaged, the bottom of the front cover 303 is disengaged from the frame housing 302. After replacing the new sound insulation panel 4, the operation is reversed, thereby achieving the purpose of quickly replacing and installing the sound insulation panel 4.
