Description

Technical Field

[0001] This utility model relates to the field of server chassis technology, and specifically to a waterproof structure for a server chassis. Background Technology

[0002] With the development of servers, they are no longer limited to use in server racks or server rooms; they can also be used in outdoor settings such as outdoor performances and conferences. For servers used outdoors, the server chassis needs to be waterproof to prevent water from entering the chassis due to rain or accidental splashes, thus avoiding damage to the internal components. Since there are gaps between the server chassis and the door, current technology typically uses sealing strips to seal these gaps. However, this method is not foolproof as a single sealing strip cannot guarantee a proper seal, and the sealing strip is prone to aging over time, resulting in poor waterproofing. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a waterproof structure for a server chassis. When the chassis is closed by a cover plate, the pressure-bearing portions of a first sealing element and a compression elastic element are simultaneously compressed. This causes the first sealing element to deform, providing a primary seal between the cover plate and the chassis. At the same time, the deformation portion of the compression elastic element also compresses the first sealing element. In this process, the interaction between the deformation portion of the compression elastic element and the first sealing element increases the interaction between the first sealing element and the inner wall of the waterproof groove and the cover plate, thus enhancing the sealing effect. Furthermore, the two pressure-bearing portions of the compression elastic element can press firmly against the bottom wall of the waterproof groove and the cover plate respectively, forming a secondary seal and improving the waterproof performance of the server chassis.

[0004] This utility model provides a waterproof structure for a server chassis to solve the above-mentioned technical problems. It includes a chassis body and a cover plate disposed on the chassis body. A waterproof groove is provided on the side of the chassis body near the cover plate. A first sealing element and a compression elastic element are arranged around the waterproof groove. The compression elastic element includes a deformable part and two sets of pressure-bearing parts arranged parallel to both ends of the deformable part. One of the pressure-bearing parts contacts the bottom of the waterproof groove, and the other pressure-bearing part extends to the outside of the opening side of the waterproof groove. The deformable part can compress the first sealing element.

[0005] Furthermore, the first sealing element includes a sealing body placed in the waterproof groove, the sealing body having a groove on the side near the cover plate, and two sealing lips extending out of the groove and opening inward and outward on both sides.

[0006] Furthermore, the sealing body has two sealing protrusions extending out of the waterproof groove on the side near the cover plate, and the two sealing protrusions are respectively located on the inner and outer sides of the groove.

[0007] Furthermore, the cover plate has a mounting groove on the side near the box body, and a second sealing element corresponding to the sealing protrusion is provided in the mounting groove.

[0008] Furthermore, the cross-section of the deformed part is arc-shaped, and the opening side of the deformed part faces the sidewall of the waterproof groove.

[0009] Furthermore, sealing gaskets are provided on the opposite sides of the two sets of pressure-bearing parts.

[0010] The beneficial effects of this utility model are as follows: the waterproof groove is used to accommodate the first sealing element and the compression elastic element, ensuring a stable connection between them and the housing. The first sealing element and the compression elastic element interact to seal the gap between the housing and the cover plate. When the cover plate is placed on the housing, it compresses the first sealing element and the compression elastic element. During the compression process, the first sealing element deforms, forming a primary sealing structure between the cover plate and the housing. Meanwhile, as one of the pressure-bearing parts of the extrusion elastic element contacts the bottom of the waterproof groove, when the cover plate acts on the pressure-bearing part of the extrusion elastic element extending to the opening side of the waterproof groove, the deformable part of the extrusion elastic element also deforms towards the first seal under the action of the cover plate, thereby extruding the first seal. Since the forces are mutual, the interaction between the first seal and the deformable part of the extrusion elastic element increases the interaction between the first seal and the inner wall of the waterproof groove and the cover plate, improving the sealing effect. It also allows the two pressure-bearing parts of the extrusion elastic element to press against the bottom wall of the waterproof groove and the inner wall of the cover plate respectively, forming a secondary seal. Through the interaction between the first seal and the extrusion elastic element, a two-stage seal between the enclosure and the cover plate is achieved, and the stability of the two-stage seal is ensured, improving the sealing effect of the server enclosure and the waterproof effect of the server enclosure.

Detailed Implementation

[0015] Referring to the accompanying drawings, the specific embodiments of this utility model will be described in detail.

[0016] Reference Figures 1 to 2 This utility model provides a waterproof structure for a server chassis, including a chassis 1 and a cover plate 2 mounted on the chassis 1. The cover plate 2 can be fixed to the chassis 1 with bolts. For example, the chassis 1 has threaded connection holes around an opening, and the cover plate 2 has through holes. The bolts pass through the through holes and connect to the threaded connection holes. In this case, the cover plate 2 is pulled towards the chassis 1 by the bolts and threaded connection holes, causing the cover plate 2 to press against the first sealing element 3 and the elastic element 4 in the waterproof groove 11. Alternatively, the cover plate 2 and the chassis 1 can be installed using a snap-lock. For example, one side of the cover plate 2 is hinged to one side of the chassis 1, and a snap-lock is provided on the other side. A corresponding latch is provided on the chassis 1, and the latch is locked by pressing the locking block of the snap-lock into the latch.

[0017] The box body 1 is provided with a waterproof groove 11 on the side near the cover plate 2. The waterproof groove 11 is arranged around the opening of the box body 1. When the cover plate 2 is fixed to the box body 1 by bolts, the waterproof groove 11 bypasses the threaded connection hole and the threaded connection hole is located outside the waterproof groove 11.

[0018] The waterproof groove 11 is surrounded by a first sealing element 3 and a compression elastic element 4. The first sealing element 3 and the compression elastic element 4 extend in the same direction as the waterproof groove 11 and fit snugly against the waterproof groove 11 when placed inside it. The compression elastic element 4 can be placed on either the inner or outer ring side of the waterproof groove 11. The first sealing element 3 can be made of rubber or plastic.

[0019] In this embodiment, the compression elastic element 4 is placed on the outer ring side of the waterproof groove 11, and the first sealing element 3 is placed on the inner ring side of the waterproof groove 11. The deformation direction of the compression elastic element 4 is towards the first sealing element 3, so that when the compression elastic element 4 is compressed, it can deform and compress the first sealing element 3, forming an interaction force with the first sealing element 3 to seal the gap between the box body 1 and the cover plate 2.

[0020] In some embodiments, the extrusion elastic member 4 includes a deformable portion 42 and two sets of pressure-bearing portions 41 arranged parallel to both ends of the deformable portion 42. One of the pressure-bearing portions 41 contacts the bottom of the waterproof groove 11, and the other pressure-bearing portion 41 extends to the outside of the opening side of the waterproof groove 11. The deformable portion 42 can compress the first sealing member 3. Further, sealing gaskets 5 are provided on the opposite sides of the two sets of pressure-bearing portions 41. When the pressure-bearing portion 41 of the extrusion elastic member 4 is compressed, the sealing gaskets 5 on the two sets of pressure-bearing portions 41 can deform and make tight contact with the cover plate 2 and the bottom wall of the waterproof groove 11 to achieve a seal. The pressure-bearing portion 41 can be configured in various shapes, such as cylindrical, plate, etc. In this embodiment, a plate structure is adopted. The cross-section of the deformable portion 42 can also be configured in various shapes, such as V-shaped, arc-shaped, etc. In this embodiment, the cross-section of the deformable portion 42 is arc-shaped, and the opening side of the deformable portion 42 faces the side wall of the waterproof groove 11. When the pressure-bearing part 41 is subjected to pressure, the deformation part 42 deforms and squeezes the sealing body 31 of the first sealing element 3.

[0021] At this time, the cover plate 2 squeezes the first sealing element 3 and the compression elastic element 4. The first sealing element 3 deforms during the squeezing process, forming a primary sealing structure between the cover plate 2 and the box body 1. Meanwhile, as the pressure-bearing part 41 of the compression elastic element 4 contacts the bottom of the waterproof groove 11, when the cover plate 2 acts on the pressure-bearing part 41 of the compression elastic element 4 extending to the opening side of the waterproof groove 11, the deformation part 42 of the compression elastic element 4 also deforms towards the first seal 3 under the action of the cover plate 2, thereby compressing the first seal 3. Since the forces are mutual, the interaction between the first seal 3 and the deformation part 42 of the compression elastic element 4 increases the interaction between the first seal 3 and the inner wall of the waterproof groove 11 and the cover plate 2, improving the sealing effect. It also allows the two pressure-bearing parts 41 of the compression elastic element 4 to press against the bottom wall of the waterproof groove 11 and the inner side wall of the cover plate 2 respectively to form a secondary seal. Through the interaction between the first seal 3 and the compression elastic element 4, the two-stage seal of the enclosure 1 and the cover plate 2 is achieved, and the stability of the two-stage seal is ensured, improving the sealing effect of the server enclosure and the waterproof effect of the server enclosure.

[0022] In some embodiments, the first sealing element 3 includes a sealing body 31 placed within the waterproof groove 11, with one end of the sealing body 31 extending out of the opening of the waterproof groove 11, allowing the sealing body 31 to be compressed when the cover plate 2 is closed. The cross-sectional shape of the sealing body 31 can be circular or quadrilateral; in this embodiment, the sealing body 31 has a rectangular cross-section. Furthermore, when the sealing body 31 is placed into the waterproof groove 11, one side of the sealing body 31 rests on the pressure-bearing portion 41 at the bottom of the compression elastic member 4, while the other side of the sealing body 31 is spaced apart from another pressure-bearing portion 41. When it is necessary to remove the first sealing element 3, pulling the outer pressure-bearing portion 41 will cause the compression elastic member 4 to detach from the waterproof groove 11, thereby pulling the first sealing element 3 out of the waterproof groove 11.

[0023] The sealing body 31 has a groove 32 on the side near the cover plate 2. Two sealing lips 33 extend from the opening of the groove 32 and open inwards and outwards. During the closing process, the cover plate 2 first contacts the two sealing lips 33. As the closing process continues, the sealing lips 33 are compressed, causing them to open further to both sides. The edges of the sealing lips 33 fit tightly against the cover plate 2, achieving further sealing. Since both sealing lips 33 are in close contact with the cover plate 2, the gap between them is sealed. With continuous compression, the air inside is squeezed out, and the two sealing lips 33 also create an adsorption effect with the cover plate 2, further ensuring the sealing between the cover plate 2 and the housing 1.

[0024] Furthermore, the sealing body 31 has two sealing protrusions 34 extending out of the waterproof groove 11 on the side near the cover plate 2. The two sealing protrusions 34 are located on the inner and outer sides of the groove 32, respectively. In this case, the inner and outer sealing protrusions 34 further increase the contact points with the cover plate 2, achieving a stronger seal and ensuring a better sealing effect. Furthermore, the cover plate 2 has an installation groove 21 on the side near the housing 1. The installation groove 21 contains a second sealing element 22 corresponding to the sealing protrusions 34. The second sealing element 22 can be made of rubber or plastic. In this case, the second sealing element 22 presses against the sealing protrusions 34, causing them to interact and further improve the sealing effect.
