Description

Technical Field

[0001] This utility model relates to the field of dustproof chassis technology, and in particular to a dustproof structure and chassis. Background Technology

[0002] Server and other equipment chassis typically improve heat dissipation by enhancing airflow. To prevent dust and other environmental contaminants from entering the chassis through the air intake and affecting the normal operation and lifespan of internal components, or from clogging the air intake and impairing heat dissipation, dustproof structures are usually installed on the chassis.

[0003] To ensure the reliability of the dustproof components on the chassis and to facilitate maintenance, most existing dustproof components are detachably installed on the chassis using bolts, but the disassembly and assembly process is rather cumbersome. Utility Model Content

[0004] Therefore, it is necessary to provide a dustproof structure and chassis to address the above problems, so as to ensure the reliability of the dustproof structure and facilitate its disassembly or maintenance.

[0005] This utility model provides a dustproof structure, including: a hanging nail for being installed on the side wall of a box; an installation component including a frame and a hook and a magnetic component installed on the frame, wherein the hook is detachably hung on the hanging nail and the magnetic component is used to be attracted to the side wall of the box; and a dustproof component installed on the frame, wherein in the assembled state, the dustproof component covers the air inlet of the box.

[0006] In the aforementioned dustproof structure, during assembly, the dustproof components are first placed on the frame, and then the frame is hung on the hooks and pins. The magnetic components are attached to the side wall of the enclosure. The hooks and pins facilitate alignment by the user, ensuring the dustproof components are aligned with the air inlet of the enclosure. The dustproof components filter the air entering the enclosure through the air inlet, preventing dust from entering and affecting the normal operation and lifespan of the internal components. They also prevent dust from clogging the air inlet and affecting the heat dissipation performance of the enclosure. The magnetic components and hooks together fix the frame to the side wall of the enclosure, ensuring the stability and reliability of the dustproof structure on the enclosure. This prevents vibration of the dustproof structure relative to the enclosure from affecting the dustproof effect or the performance of the enclosure. At the same time, it also facilitates the removal of the mounting components and dustproof components from the enclosure, making it easy to disassemble, install, or maintain the dustproof structure.

[0007] In one embodiment, the side of the magnetic clasp facing the housing is flush with the side of the frame facing the housing.

[0008] This design ensures that both the side of the magnetic connector facing the box and the side of the frame facing the box can simultaneously adhere to the side wall of the box, guaranteeing no gap between the frame and the box, while maximizing the magnetic attraction between the magnetic connector and the box.

[0009] In one embodiment, the mounting assembly further includes a first fastener, by which the magnetic chuck and the frame are detachably secured; the side of the first fastener facing the housing is flush with the side of the magnetic chuck facing the housing.

[0010] This design makes fixing simple and easy to assemble; and the flat surface of the magnetic parts against the box body enhances the adsorption effect.

[0011] In one embodiment, the frame includes a first shell and a second shell that enclose a mounting cavity, the dustproof component is disposed inside the mounting cavity, and the first shell and the second shell are each provided with a ventilation opening corresponding to the dustproof component.

[0012] With this configuration, the mounting cavity formed by the first and second shells can position the dustproof components and also facilitate the disassembly or replacement of the dustproof components.

[0013] In one embodiment, the first shell is disposed on the side of the second shell away from the housing, and the first shell has a mounting portion protruding from one side facing the second shell. The magnetic suction member is disposed on the mounting portion, and the second shell has a clearance hole corresponding to the mounting portion.

[0014] This design allows the clearance hole to prevent the mounting part and the magnetic component from interfering with each other with the second shell, and the mounting part protruding towards the housing allows the magnetic component with a smaller thickness to get closer to the housing.

[0015] In one embodiment, the mounting assembly further includes a plurality of second fasteners, the first housing and the second housing being detachably secured by the second fasteners, the plurality of second fasteners being arranged circumferentially spaced along the vent.

[0016] With this configuration, the second fastener can ensure the stability and reliability of the first and second shells in the assembled state, and facilitate disassembly and assembly. The multiple second fasteners arranged at intervals along the circumference of the ventilation opening can limit the position of the dustproof components.

[0017] In one embodiment, the pin has a first groove, and the hook is hung in the first groove; and / or, the hook has a second groove with its opening facing downward, and the hook is hung on the pin through the second groove, and the hook also has a guide slope extending outward from the opening of the second groove.

[0018] This design allows for the limiting of the dustproof structure, improving its stability and reliability within the enclosure.

[0019] In one embodiment, the top of the frame is provided with a flange for overlapping the top wall of the box.

[0020] This design allows the flange to position the mounting components and also to support them, preventing them from sliding downwards relative to the enclosure under gravity and ensuring that the dust cover is positioned at the air inlet of the enclosure.

[0021] In one embodiment, there are multiple hooks and multiple hooks, with the hooks arranged at intervals along the circumference of the frame, and the hooks and hooks arranged in a one-to-one correspondence; and / or, there are multiple magnetic components, with the magnetic components arranged at intervals along the circumference of the frame.

[0022] This design allows multiple hooks and pins to work together to precisely position the installation components and prevent them from rotating around one of the pins; multiple magnetic attachments ensure that the frame can be magnetically attached to the side wall of the box at every point along its circumference.

[0023] This utility model embodiment also provides a chassis, including a chassis body and the aforementioned dustproof structure, wherein the chassis body is provided with an air inlet.

[0024] With this setup, the dustproof structure is not affected by the structural dimensions of the enclosure, and only requires the installation of hanging nails on the side wall of the enclosure. It does not require any changes to the enclosure's own structural design, making it widely applicable. Attached Figure Description

[0041] Server and other equipment chassis typically improve heat dissipation by enhancing airflow. To prevent dust and other contaminants from entering the chassis through the air intake and affecting the normal operation and lifespan of internal components, or from clogging the air intake and impairing heat dissipation, dustproof structures are usually installed on the chassis. To ensure the reliability of these dustproof structures and to facilitate maintenance, most existing dustproof structures are detachably bolted to the chassis, but the disassembly and assembly process is relatively cumbersome.

[0042] To solve the above problems, such as Figures 1 to 9 As shown, this utility model first provides a dustproof structure to ensure the reliability of the dustproof structure, while also facilitating the disassembly or maintenance of the dustproof structure.

[0043] like Figure 1 , Figure 3 and Figure 4As shown, specifically, the dustproof structure includes a hanging nail 1, an installation component 2, and a dustproof component 3, wherein: the hanging nail 1 is used to be installed on the side wall of the box 4; the installation component 2 includes a frame 21 and a hook 22 and a magnetic component 23 installed on the frame 21, the hook 22 is detachably hung on the hanging nail 1, and the magnetic component 23 is used to be attracted to the side wall of the box 4; the dustproof component 3 is installed on the frame 21, and in the assembled state, the dustproof component 3 covers the air inlet 41 of the box 4.

[0044] In the dustproof structure provided in this embodiment of the utility model, during the assembly process, the dustproof component 3 is first placed on the frame 21, and then the frame 21 is hung on the hanging nail 1 via the hook 22. The magnetic component 23 is attracted to the side wall of the box 4. The hook 22 and the hanging nail 1 cooperate to facilitate the user's alignment, so that the dustproof component 3 is aligned with the air inlet 41 of the box 4. The dustproof component 3 can filter the air entering the box 4 through the air inlet 41, preventing dust and other particles from entering the box 4 and affecting the normal operation and service life of the internal components of the box 4. It also prevents dust from clogging the air inlet 41 and affecting the heat dissipation performance of the box 4. The magnetic component 23 and the hook 22 together fix the frame 21 to the side wall of the box 4, which can ensure the stability and reliability of the dustproof structure on the box 4, prevent the dustproof structure from vibrating relative to the box 4 and affecting the dustproof effect or the performance of the box 4. At the same time, it can also facilitate the removal of the mounting component 2 and the dustproof component 3 from the box 4, thereby facilitating the disassembly, assembly or maintenance of the dustproof structure.

[0045] It should be noted that when the dustproof component 3 is placed on the air inlet 41 of the housing 4, it means that the projection of the dustproof component 3 on the housing 4 completely covers the air inlet 41.

[0046] The magnetic suction component 23 can be a magnet. The side wall of the housing 4, which has at least an air inlet 41, is made of sheet metal or other metals with iron content to ensure that there is a sufficiently strong magnetic attraction between the magnet and the side wall of the housing 4, so that the dustproof structure will not fall off after being fixed to the side wall of the housing 4 by the magnetic suction component 23 and the hook 22.

[0047] like Figure 5 and Figure 7As shown, in one embodiment, the side of the magnetic suction member 23 facing the housing 4 is flush with the side of the frame 21 facing the housing 4. This ensures that both the side of the magnetic suction member 23 and the side of the frame 21 facing the housing 4 can simultaneously adhere to the side wall of the housing 4, guaranteeing no gap between the frame 21 and the housing 4 and preventing dust from entering the air inlet 41 through this gap. Simultaneously, the adherence of the magnetic suction member 23 to the side wall of the housing 4 maximizes the magnetic attraction between the magnetic suction member 23 and the housing 4, thereby improving the stability and reliability of the dustproof structure on the housing 4. Of course, in other embodiments, the side of the magnetic member 23 facing the housing 4 can also be away from the housing 4 relative to the side of the frame 21 facing the housing 4. That is, when the side of the frame 21 facing the housing 4 is attached to the side wall of the housing 4, there is a gap between the side of the magnetic member 23 facing the housing 4 and the side wall of the housing 4, as long as the magnetic attraction between the magnetic member 23 and the housing 4 is sufficient to stably fix the dustproof structure to the housing 4. Furthermore, the user can adjust the thickness of the magnetic member 23 according to the required magnetic attraction force.

[0048] like Figures 5 and 6 As shown, in one embodiment, the mounting assembly 2 further includes a first fastener 24, and the magnetic component 23 and the frame 21 are detachably fixed by the first fastener 24. The magnetic component 23 is fixed to the frame 21 by the first fastener 24, which is a simple fixing method and facilitates assembly. The first fastener 24 can be other fasteners such as rivets, screws, bolts, and nuts. Furthermore, the side of the first fastener 24 facing the housing 4 is flush with the side of the magnetic component 23 facing the housing 4, making the contact surfaces of the magnetic component 23 and the housing 4 flat, thereby improving the adsorption effect. Alternatively, the side of the first fastener 24 facing the housing 4 is further away from the housing 4 than the side of the magnetic component 23 facing the housing 4, that is, the side of the first fastener 24 facing the housing 4 does not protrude from the side of the magnetic component 23 facing the housing 4 or the side of the frame 21 facing the housing 4, to ensure that there is no gap between the frame 21 and the housing 4. Figure 9 As shown, specifically, the first fastener 24 is configured as a bolt and a nut, the magnetic component 23 is provided with a slotted hole 231, the nut is disposed on the frame 21, and the threaded portion of the bolt passes through the large-diameter section and the small-diameter section of the slotted hole 231 in sequence and is fixed to the nut by thread engagement, with the bolt head embedded in the large-diameter section. Of course, in other embodiments, the magnetic component 23 can also be fixed to the frame 21 by other methods such as adhesive or snap-fit, as long as the stability and reliability of the connection between the magnetic component 23 and the frame 21 can be guaranteed. This embodiment of the present invention does not impose specific limitations here.

[0049] like Figure 6As shown, the frame 21 includes a first shell 211 and a second shell 212 that enclose a mounting cavity. A dustproof component 3 is disposed within the mounting cavity. Both the first shell 211 and the second shell 212 have ventilation openings 213 corresponding to the dustproof component 3. The mounting cavity formed by the first shell 211 and the second shell 212 can position the dustproof component 3, ensuring that in the assembled state, both the dustproof component 3 and the ventilation openings 213 are aligned with the air inlet 41, and also facilitating the disassembly or replacement of the dustproof component 3. The ventilation opening 213 can be a mesh structure as shown in the figure, or it can be a strip structure or a complete through hole, etc. This embodiment of the invention does not impose specific limitations. The first shell 211 and the second shell 212 can be metal shells to ensure the strength of the frame 21. Furthermore, the dustproof structure has a simple structure and a small thickness, minimizing its volume and avoiding an increase in the overall size of the chassis.

[0050] like Figure 6 As shown, in one embodiment, the mounting assembly 2 further includes a plurality of second fasteners 25. The first shell 211 and the second shell 212 are detachably fixed by the second fasteners 25, and the plurality of second fasteners 25 are arranged circumferentially around the ventilation opening 213. The second fasteners 25 can ensure the stability and reliability of the first shell 211 and the second shell 212 in the assembled state, and are easy to disassemble and assemble. The circumferential arrangement of the plurality of second fasteners 25 around the ventilation opening 213 can also limit the dustproof component 3, preventing the dustproof component 3 from moving in the mounting cavity and affecting the dustproof effect. The second fasteners 25 can be set as rivets, screws, bolts, nuts and other fasteners. Of course, in other embodiments, the first shell 211 and the second shell 212 can also be detachably fixed by other means such as snaps, magnetic attraction, etc., as long as the stability and reliability of the first shell 211 and the second shell 212 in the assembled state can be guaranteed. This embodiment of the present invention does not impose specific limitations.

[0051] like Figure 5 and Figure 8As shown, in one embodiment, a first shell 211 is disposed on the side of the second shell 212 away from the housing 4. A mounting portion 214 protrudes from the side of the first shell 211 facing the second shell 212, and a magnetic suction member 23 is disposed on the mounting portion 214. The second shell 212 has a clearance hole 2121 corresponding to the mounting portion 214. The clearance hole 2121 prevents the mounting portion 214 and the magnetic suction member 23 from interfering with the second shell 212, facilitating the installation of the magnetic suction member 23. The mounting portion 214 is disposed on the first shell 211 so that the magnetic suction member 23 does not protrude from the side of the second shell 212 facing the housing 4. Furthermore, the mounting portion 214 protruding towards the housing 4 allows the thinner magnetic suction member 23 to be closer to the housing 4, thereby increasing the magnetic attraction between the magnetic suction member 23 and the housing 4, and improving the stability and reliability of the dustproof structure on the housing 4. The user can adjust the thickness of the mounting part 214 according to the thickness of the magnetic component 23, so that the magnetic component 23 fits snugly against the side wall of the housing 4. Of course, in other embodiments, a mounting groove can also be opened on the side of the second shell 212 opposite to the first shell 211, and the magnetic component 23 can be embedded in the mounting groove so that the magnetic component 23 does not protrude from the side of the second shell 212 facing the housing 4.

[0052] like Figure 4 As shown, there are multiple magnetic suction components 23, which are arranged at intervals along the circumference of the frame 21. This ensures that every point along the circumference of the frame 21 can adhere to the side wall of the box 4 under the action of magnetic attraction, thereby further improving the stability and reliability of the connection between the frame 21 and the box 4. The number of magnetic suction components 23 can be 2, 3, 4, or more. In the illustrated embodiment, there are 8 magnetic suction components 23, arranged in two rows. The two rows of magnetic suction components 23 are respectively located on both sides of the frame 21, with each row including 4 magnetic suction components 23.

[0053] like Figure 2 and Figure 5 As shown, the hook 1 has a first groove 11, and the hook 22 is hung in the first groove 11. The first groove 11 can prevent the hook 22 from moving relative to the hook 1 in a direction perpendicular to the side wall of the box 4, or cause the hook 22 to accidentally fall off the hook 1 to the side away from the side wall of the box 4, thereby improving the stability and reliability of the hook 22 when it is hung on the hook 1.

[0054] like Figure 2 and Figure 5As shown, the hook 22 has a second groove 221 with its opening facing downwards. The hook 22 is hung on the nail 1 through the second groove 221. The hook 22 also has a guide slope 222 extending outwards from the opening of the second groove 221. The second groove 221 can prevent the hook 22 from moving relative to the nail 1 in a direction parallel to the side wall of the box 4, thereby further improving the stability and reliability of the hook 22 when it is hung on the nail 1. The guide slope 222 can facilitate the user to position the hook 22 and the nail 1, thereby facilitating the user to install the dustproof structure. When installing the installation component 2, first align the opening of the second groove 221 with the nail 1, and then control the installation component 2 to slide downwards. The nail 1 can slide and engage in the second groove 221 under the action of the guide slope 222, so that the hook 22 is hung on the nail 1. Through the cooperation of the first groove 11 and the second groove 221, the dustproof structure can be limited, improving the stability and reliability of the dustproof structure on the box 4.

[0055] like Figure 1 and Figure 3 As shown, there are multiple hooks 22 and pins 1. The hooks 22 are arranged at intervals along the circumference of the frame 21, and the pins 1 correspond one-to-one with the hooks 22. The multiple hooks 22 and pins 1 work together to precisely position the mounting component 2, preventing it from rotating around one of the pins 1, ensuring the dustproof component 3 is properly positioned at the air inlet 41 of the housing 4, and further improving the stability and reliability of the dustproof structure on the housing 4. The number of hooks 22 can be two, three, four, or more. In the illustrated embodiment, there are two hooks 22, located on the same side of the frame 21. Alternatively, the two hooks 22 can be located on opposite sides of the frame 21.

[0056] like Figures 2 to 3 As shown, the top of the frame 21 is provided with a flange 215, which is used to overlap the top wall of the box 4. The flange 215 can position the mounting component 2 and also support the mounting component 2, preventing the mounting component 2 from sliding downward relative to the box 4 under the action of gravity, further improving the stability and reliability of the dustproof structure on the box 4, and also ensuring that the dustproof component 3 covers the air inlet 41 of the box 4.

[0057] like Figure 1 and Figure 3As shown, this embodiment of the utility model also provides a chassis, including a chassis 4 and the aforementioned dustproof structure. The chassis 4 is provided with an air inlet 41. The dustproof structure uses magnetic attachments 23 and hooks 22 to fix the frame 21 to the side wall of the chassis 4, ensuring the stability and reliability of the dustproof structure on the chassis 4, preventing vibration of the dustproof structure relative to the chassis 4 from affecting the dustproof effect or the performance of the chassis 4. It also facilitates disassembly and maintenance of the dustproof structure. The dustproof component 3 of the dustproof structure filters the air entering the chassis 4 through the air inlet 41, preventing dust and other contaminants from entering the chassis 4 and affecting the normal operation and lifespan of the internal components. It also prevents dust from clogging the air inlet 41 and affecting the heat dissipation performance of the chassis 4. This dustproof structure is not affected by the structural dimensions of the chassis 4 and only requires the installation of hanging nails 1 on the side wall of the chassis 4, without changing the structural design of the chassis 4, making it widely applicable.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
