Description

Technical Field

[0001] This utility model relates to the field of dust protection, and more particularly to dust protection kits and chassis. Background Technology

[0002] In the routine maintenance of server and power amplifier enclosures, dustproof cotton serves as a critical protective component. By preventing external dust from entering the enclosure, it effectively ensures the stable operation of internal hardware devices (such as circuit boards and heat dissipation modules). However, the existing dustproof cotton replacement procedure has significant drawbacks, as follows:

[0003] The current replacement method requires first removing the chassis panel, then manually or with the help of simple tools to pull the old dust filter out of the vent, and finally inserting and securing the new dust filter. However, due to long-term exposure to airflow and ambient temperature and humidity, the edges of the dust filter tend to adhere to the metal frame of the vent. When removing the old dust filter, some fibers break due to adhesion and remain in the vent gaps, making subsequent cleaning difficult. Furthermore, the residue obstructs airflow, reducing heat dissipation efficiency.

[0004] Furthermore, the installation of the new dustproof cotton lacks standardized positioning methods, making it difficult to ensure even force distribution when manually inserting it, resulting in poor dustproof performance. Moreover, the disassembly and assembly of the dustproof surface is cumbersome; in dense data center scenarios, frequent maintenance will significantly increase operation and maintenance costs. Utility Model Content

[0005] This utility model provides a dustproof kit and chassis that can solve the problems of easy adhesion and residue during disassembly, reduced dustproof effect after maintenance and replacement, and cumbersome disassembly and assembly.

[0006] This utility model provides a dustproof kit, which is disposed on a housing, and the housing has ventilation openings. The dustproof kit includes:

[0007] A fixing mechanism includes a movable component and a rotating component. The movable component is provided with a mounting position and several through holes, each of which communicates with the mounting position. The movable component is rotatably connected to the housing via the rotating component.

[0008] A dustproof mechanism is detachably installed in the mounting position, and the dustproof mechanism shields each of the through holes;

[0009] When the movable component is rotated to the dustproof position, the dustproof mechanism is confined within the mounting position by the inner wall of the vent; when the movable component is rotated to the disassembly position, at least a portion of the mounting position is exposed outside the vent, thereby allowing the dustproof mechanism to be disengaged from the mounting position.

[0010] Preferably, the rotating assembly includes a rotating shaft and a rotating hole;

[0011] One of the rotating shaft and the rotating hole is disposed on the movable component, and the other of the rotating shaft and the rotating hole is disposed on the inner wall surface of the vent. The rotating shaft is rotatably connected to the rotating hole.

[0012] Preferably, the movable component includes a ventilation plate and two limiting edges, each of the through holes is located on the ventilation plate, the two limiting edges are symmetrically arranged on the ventilation plate, the two limiting edges define the mounting position on the ventilation plate, and the limiting edges or the ventilation plate are connected to the housing through the rotating component.

[0013] Preferably, the cross-section of each of the limiting edges is L-shaped.

[0014] Preferably, the dustproof mechanism includes dustproof cotton.

[0015] Preferably, the fixing mechanism further includes a limiting component disposed between the movable component and the vent, the limiting component being used to limit the maximum rotation angle of the movable component on the housing.

[0016] Preferably, the limiting component includes a limiting protrusion disposed on the housing, and when the movable component is rotated to the disassembly position, the movable component abuts against the limiting protrusion.

[0017] Preferably, the limiting component includes a limiting protrusion and a limiting groove. The limiting protrusion is disposed on the movable component, and the limiting groove is disposed on the wall of the vent. The limiting protrusion slides along the limiting groove under the drive of the movable component. When the movable component rotates to the disassembly position, the limiting protrusion abuts against the inner wall of the limiting groove.

[0018] Preferably, the dustproof kit further includes a magnetic attraction mechanism, which includes a magnetic block disposed on the housing or the movable component;

[0019] When the movable component rotates to the dustproof position, the movable component and the housing are magnetically connected by the magnetic block.

[0020] Preferably, the magnetic attraction mechanism further includes a protruding arm with a mounting hole, the protruding arm being disposed on the inner wall surface of the vent, and the magnetic block being disposed within the mounting hole;

[0021] The dustproof mechanism includes dustproof cotton, and the dustproof cotton has a clearance hole, which corresponds to the protruding arm.

[0022] The second aspect of this utility model also provides a chassis, which includes a chassis body and a dustproof kit as described in any of the above technical solutions, wherein the housing is disposed on the chassis body.

[0023] The following are the beneficial effects of implementing this utility model:

[0024] This utility model relates to a dustproof kit and a chassis. The dustproof kit is mounted on a housing, which in turn is mounted on a chassis. The dustproof kit incorporates a fixing mechanism consisting of movable and rotating components, allowing the dustproof mechanism to detach from the inner wall of the ventilation opening when rotated to the disassembly position. This prevents the dustproof mechanism from physically adhering to the metal frame, effectively solving the problem of dustproof structure residue.

[0025] Furthermore, the dustproof kit also defines the structure by fitting the mounting position with the inner wall of the vent, so that the dustproof mechanism can be positioned in a standardized manner when the moving component is rotated to the dustproof position, ensuring that the dustproof mechanism can fully protect the vent from dust.

[0026] Secondly, the dustproof kit uses rotating movable components instead of the traditional fixed frame, allowing for replacement of the dustproof mechanism without disassembling the chassis panel. The disassembly and assembly can be completed simply by rotating the components, improving maintenance convenience and significantly reducing maintenance complexity in data center-intensive environments. It also avoids errors caused by manual visual alignment during installation, effectively preventing airflow leakage due to assembly errors.

[0027] Furthermore, the detachable connection between the mounting position and the dustproof mechanism eliminates the need for adhesive bonding between the dustproof mechanism and the moving components, thereby further preventing any residue from disassembling the dustproof mechanism.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] Figure 1 The dustproof kit 10 shown is illustrated in some embodiments of the present invention. The dustproof kit 10 can be applied to various vents, ventilation channels or other airflow structures that require dust protection.

[0046] like Figures 1 to 3 As shown, the dustproof kit 10 is disposed on the housing 30, and the housing 30 has a ventilation opening 40. The shape, structure, size, material, or various specifications of the housing 30 are not limited, and the outline and specifications of the ventilation opening 40 can also be flexibly set. The ventilation opening 40 is used for airflow exchange. The dustproof kit 10 of this utility model is for dustproof sealing of the ventilation opening 40.

[0047] like Figures 2 to 5 As shown, the dustproof kit 10 includes a fixing mechanism 1 and a dustproof mechanism 2. The fixing mechanism 1 is disposed on the housing 30, and the dustproof mechanism 2 is disposed on the fixing mechanism 1. Understandably, the fixing mechanism 1 is movable relative to the housing 30 and also serves to fix the dustproof mechanism 2. The dustproof mechanism 2 is used to filter the flowing air, thereby achieving the purpose of dust prevention.

[0048] like Figures 2 to 10 As shown, the fixing mechanism 1 includes a movable component 11 and a rotating component 12. The movable component 11 is provided with a mounting position 113 and several through holes 1111. Each through hole 1111 is connected to the mounting position 113. The movable component 11 is rotatably connected to the housing 30 through the rotating component 12.

[0049] The dustproof mechanism 2 is detachably mounted within the mounting position 113, and the dustproof mechanism 2 shields each through hole 1111. When the movable component 11 is rotated to the dustproof position D1, the dustproof mechanism 2 is confined within the mounting position 113 by the inner wall of the vent 40. When the movable component 11 is rotated to the detached position D2, at least a portion of the mounting position 113 is exposed outside the vent 40, thereby allowing the dustproof mechanism 2 to be disengaged from the mounting position 113.

[0050] Understandably, the movable component 11 is rotatably connected to the housing 30 via the rotating component 12, which limits the movable component 11 to rotate around a preset axis on the housing 30. The movable component 11 has a mounting position 113, which is formed by a receiving groove, receiving hole, limiting wall, or other structure with protrusions that matches the shape of the dustproof mechanism 2; of course, the mounting position 113 can also be configured as other structures that can accommodate the dustproof mechanism 2. The surface of the movable component 11 also has several through holes 1111, each of which communicates with the mounting position 113 and guides airflow through the dustproof mechanism 2. The dustproof mechanism 2 can be configured as a sheet-like filter structure, which is detachably installed in the mounting position 113 and completely covers all the through holes 1111, thus filtering the airflow.

[0051] It should be noted that when the movable component 11 is rotated to the dustproof position D1, the inner wall of the vent 40 and the mounting position 113 form spatial interference, limiting and fixing the dustproof mechanism 2. When the movable component 11 is rotated to the disassembly position D2, part of the mounting position 113 is exposed outside the vent 40, releasing the limiting constraint on the dustproof mechanism 2, allowing the dustproof mechanism 2 to be removed from the mounting position 113; of course, when the movable component 11 is in the disassembly position D2, the dustproof mechanism 2 can also be inserted from the exposed part of the mounting position 113, thereby inserting the dustproof mechanism 2 into the mounting position 113.

[0052] It should also be noted that the rotating component 12 gives the movable component 11 a degree of rotational freedom. By rotating to switch between the dustproof position D1 and the disassembly position D2, the direct friction between the dustproof mechanism 2 and the inner wall of the vent 40 during traditional disassembly operations is avoided. At the same time, the connection between the dustproof mechanism 2 and the movable component 11 can be completed without the need for adhesives or other connecting structures, thereby quickly completing the alignment and installation of the dustproof mechanism 2 within the vent 40 and solving the problem of disassembly residue of the dustproof mechanism 2. Secondly, the receiving groove structure of the mounting position 113 provides a standardized positioning reference for the dustproof mechanism 2, ensuring that it evenly covers all through holes 1111 after installation, improving the dustproof sealing.

[0053] Furthermore, the disassembly position D2 can be configured to be a unique position, meaning that the dustproof mechanism 2 can only be disassembled or installed when the movable component 11 moves to a predetermined angle. Of course, the disassembly position D2 can also be configured to include multiple positions, meaning that the dustproof mechanism 2 can be disassembled or installed within any predetermined angle range as long as the movable component 11 moves to that angle range.

[0054] Additionally, the mounting position 113 can be configured such that only a portion of it is exposed outside the vent 40 for easy assembly and disassembly. Of course, the exact extent to which the mounting position 113 is exposed can be flexibly set, but it should be ensured that the assembly and disassembly of the dustproof mechanism 2 are not interfered with by the position of other components at this angle. The mounting position 113 can also be configured such that only when rotated to be completely exposed outside the vent 40 can the assembly and disassembly of the dustproof mechanism 2 be smoothly completed without interference from other structures.

[0055] like Figure 3 , Figure 9 and Figure 10 As shown, in some embodiments of the dustproof kit 10, the rotating assembly 12 includes a rotating shaft 121 and a rotating hole 122; one of the rotating shaft 121 and the rotating hole 122 is disposed on the movable assembly 11, and the other of the rotating shaft 121 and the rotating hole 122 is disposed on the inner wall surface of the vent 40, and the rotating shaft 121 is rotatably connected to the rotating hole 122.

[0056] Understandably, the pivot 121 is inserted into the rotation hole 122. Through this embodiment, the movable component 11 can rotate relative to the housing 30 via the pivot 121 and the rotation hole 122.

[0057] It should be noted that if the rotating shaft 121 is located on the inner wall of the vent 40, it can be integrally molded onto the housing 30. If the rotating shaft 121 is located on the movable component 11, it can be integrally molded onto the movable component 11.

[0058] Furthermore, such as Figure 11 and Figure 12 As shown, the number of rotating components 12 can be configured to be two. Each rotating component 12 includes a rotating shaft 121 and a rotating hole 122. Each rotating shaft 121 is rotatably connected to a rotating hole 122.

[0059] It should be noted that the two rotating shafts 121 can be configured to be symmetrically arranged on the movable component 11, and the two rotating holes 122 can be correspondingly arranged on the inner wall surface of the vent 40. Alternatively, the two rotating shafts 121 can be configured to be symmetrically arranged on the inner wall surface of the vent 40, and the two rotating holes 122 can be correspondingly arranged on the movable component 11.

[0060] like Figure 3 , Figure 7 , Figure 8 and Figure 12 As shown, in some embodiments of the dustproof kit 10, the movable component 11 includes a ventilation plate 111 and two limiting edges 112. Each through hole 1111 is located on the ventilation plate 111, and the two limiting edges 112 are symmetrically arranged on the ventilation plate 111. The two limiting edges 112 define an installation position 113 on the ventilation plate 111. The limiting edges 112 or the ventilation plate 111 are connected to the housing 30 through the rotating component 12.

[0061] Understandably, the two limiting edges 112 are symmetrically fixed to the two sides of the ventilation plate 111, and the space between the two limiting edges 112 corresponds to the mounting position 113, which is used to accommodate the dustproof mechanism 2.

[0062] It should be noted that the connection position between the rotating component 12 and the movable component 11 can be configured in at least two ways: First, the limiting edge 112 is connected to the housing 30 via the rotating component 12; in this case, the movable component 11 can rotate around the connection position between the limiting edge 112 and the housing 30. Second, the ventilation plate 111 is connected to the housing 30 via the rotating component 12, in which case the movable component 11 can rotate around the connection position between the ventilation plate 111 and the housing 30.

[0063] Furthermore, the combination structure of the limiting edge 112 and the ventilation plate 111 forms a standardized installation position 113, ensuring that the installation position of the dustproof mechanism 2 is unique and stable, avoiding the problem of displacement caused by manual operation. Specifically, after the dustproof mechanism 2 is assembled into the installation position 113, the dustproof mechanism 2 will be limited by the ventilation plate 111 and the limiting edge 112.

[0064] like Figure 12 As shown, in some embodiments of the dustproof kit 10, the cross-section of each limiting edge 112 is L-shaped.

[0065] Understandably, the limiting edge 112 of the L-shaped cross section protects the two mutually perpendicular parts, and the limiting edge 112 can also limit the dustproof mechanism 2 from different directions through the two mutually perpendicular parts.

[0066] Specifically, in some embodiments of the dustproof kit 10, the dustproof mechanism 2 includes a dustproof cotton. It is understood that the dustproof cotton is prior art.

[0067] Furthermore, the dustproof mechanism 2 can also be configured as various filtration structures in the prior art, such as filters or other components that can filter airflow.

[0068] Furthermore, a reinforcing frame can be provided on the dustproof mechanism 2 to enhance the rigidity of the dustproof mechanism 2, prevent the dustproof mechanism 2 from becoming loose, damaged or otherwise defective, thereby ensuring the dustproof effect of the dustproof mechanism 2.

[0069] like Figure 2 and Figure 3 As shown, in some embodiments of the dustproof kit 10, the fixing mechanism 1 further includes a limiting component 13, which is disposed between the movable component 11 and the vent, and is used to limit the maximum rotation angle of the movable component 11 on the housing 30.

[0070] Understandably, the limiting component 13 precisely limits the rotation range of the movable component 11 through mechanical hard limiting, so that the movable component 11 can accurately rotate to the disassembly position D2.

[0071] like Figure 6 As shown, in some embodiments of the dustproof kit 10, the limiting component 13 includes a limiting protrusion 131, which is disposed on the housing 30. When the movable component 11 is rotated to the disassembly position D2, the movable component 11 abuts against the limiting protrusion 131.

[0072] Understandably, when the movable component 11 rotates to the disassembly position D2, the edge of the movable component 11 directly abuts against the limiting protrusion 131 on the housing 30, preventing the movable component 11 from continuing to rotate through rigid contact, thus ensuring that the termination angle of the disassembly position D2 is fixed.

[0073] In some embodiments of the dustproof kit 10, the limiting component 13 includes a limiting protrusion and a limiting groove. The limiting protrusion is disposed on the movable component 11, and the limiting groove is disposed on the wall of the vent. The limiting protrusion slides along the limiting groove under the drive of the movable component 11. When the movable component 11 rotates to the disassembly position D2, the limiting protrusion abuts against the inner wall of the limiting groove.

[0074] Understandably, the limiting protrusion on the movable component 11 slides along the limiting groove on the wall of the vent hole, and the rotation angle of the movable component 11 is limited by the size of the groove. When the movable component 11 rotates to the disassembly position D2, the limiting protrusion abuts against the inner wall of the end of the limiting groove, forming a mechanical limit; at the same time, the frictional resistance during the sliding process provides rotational damping to prevent the movable component 11 from overtraveling due to inertia.

[0075] like Figures 2 to 8 As shown, in some embodiments of the dustproof kit 10, the dustproof kit 10 further includes a magnetic attraction mechanism 3, which includes a magnetic attraction block 31 disposed on the housing 30 or the movable component 11. When the movable component 11 is rotated to the dustproof position D1, the movable component 11 and the housing 30 are magnetically connected through the magnetic attraction block 31.

[0076] Understandably, when the movable component 11 rotates to the dustproof position D1, the magnetic block 31 generates a magnetic attraction force with the corresponding metal part (the housing 30 or the movable component 11), helping to fix the movable component 11 and preventing accidental displacement caused by vibration or airflow impact. Of course, the housing 30 or the movable component 11 can be configured to be made of metal for the magnetic block 31 to magnetically connect. Alternatively, a metal part can be added to the housing 30 or the movable component 11, and the magnetic block 31 can be magnetically connected through the added metal part.

[0077] It should be noted that the magnetic block 31 can be configured to be mounted on the housing 30, so that when the movable component 11 rotates to the dustproof position D1, the movable component 11 will be magnetically attracted and fixed by the magnetic block 31 on the housing 30. Alternatively, the magnetic block 31 can be configured to be mounted on the movable component 11, so that when the movable component 11 rotates to the dustproof position D1, the magnetic block 31 will magnetically fix it to the housing 30, thereby driving the movable component 11 to be firmly fixed in the dustproof position D1.

[0078] like Figure 3 , Figure 7 and Figure 8 As shown, in some embodiments of the dustproof kit 10, the magnetic attraction mechanism 3 further includes a protruding arm 32, on which an installation hole 33 is provided. The protruding arm 32 is disposed on the inner wall surface of the vent, and the magnetic attraction block 31 is disposed in the installation hole 33. The dustproof mechanism 2 includes dustproof cotton, on which a clearance hole 21 is provided, and the clearance hole 21 corresponds to the protruding arm 32.

[0079] Understandably, the protruding arm 32 on the inner wall of the vent 40 fixes the magnetic block 31 through the mounting hole 33, ensuring that the magnetic position is aligned with the movable component 11. The clearance hole 21 on the dustproof cotton corresponds to the position of the protruding arm 32, avoiding positional interference between the dustproof cotton and the protruding arm 32, ensuring that the movable component 11 can be accurately positioned at the dustproof position D1, and ensuring the dustproof effect of the dustproof mechanism 2 on the vent 40.

[0080] Figure 11 and Figure 12 The diagram shows a chassis 20 in some embodiments of the present invention. The chassis 20 includes a housing 50 and a shell 30 disposed on the housing 50.

[0081] Understandably, the vents 40 on the housing 30 allow for airflow exchange between the interior of the enclosure 50 and the outside environment. Thus, the dustproof kit 10 filters the airflow exchanged between the enclosure 50 and the outside environment, achieving a dustproof effect.

[0082] It should be noted that the chassis 20 referred to in this utility model can be applied to different fields.

[0083] The following are the beneficial effects of implementing this utility model:

[0084] This utility model relates to a dustproof kit and a chassis. The dustproof kit is mounted on a housing, which in turn is mounted on a chassis. The dustproof kit incorporates a fixing mechanism consisting of movable and rotating components, allowing the dustproof mechanism to detach from the inner wall of the ventilation opening when rotated to the disassembly position. This prevents the dustproof mechanism from physically adhering to the metal frame, effectively solving the problem of dustproof structure residue.

[0085] Furthermore, the dustproof kit also defines the structure by fitting the mounting position with the inner wall of the vent, so that the dustproof mechanism can be positioned in a standardized manner when the moving component is rotated to the dustproof position, ensuring that the dustproof mechanism can fully protect the vent from dust.

[0086] Secondly, the dustproof kit uses rotating movable components instead of the traditional fixed frame, allowing for replacement of the dustproof mechanism without disassembling the chassis panel. The disassembly and assembly can be completed simply by rotating the components, improving maintenance convenience and significantly reducing maintenance complexity in data center-intensive environments. It also avoids errors caused by manual visual alignment during installation, effectively preventing airflow leakage due to assembly errors.

[0087] Furthermore, the detachable connection between the mounting position and the dustproof mechanism eliminates the need for adhesive bonding between the dustproof mechanism and the moving components, thereby further preventing any residue from disassembling the dustproof mechanism.

[0088] The present invention has been described in detail above with reference to the accompanying drawings. In the above embodiments, the descriptions of each embodiment have different focuses; for parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

Furthermore, it is understood that the steps in the method of the present invention embodiments can be adjusted, combined, and deleted according to actual needs, and the modules in the device of the present invention embodiments can be combined, divided, and deleted according to actual needs.
