The snap-fitting part is snap-fitted and connected to the first main body, so that the snap-fitting device fixes the functional element to stably expose the avoidance space, and the sliding part extends out of the case and is visible outside the case to remind the functional element that it is in the avoidance state.
[0069] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0070] See also Figure 1 and Figure 2 One embodiment of the present application provides a chassis 200. The chassis 200 includes a box body 2001, a box cover 2003, a functional element 2005, and a buckle device 100. The box body 2001 is provided with an opening 2013 and a receiving cavity 2011. The opening 2013 is connected to the receiving cavity 2011, and the functional element 2005 is installed in the receiving cavity 2011 of the box body 2001 through the buckle device 100. The box cover 2003 is connected to the opening 2013 of the box body 2001.

[0072] In one embodiment, the chassis 200 further includes a bracket 2007 and a GPU (graphics processing unit) module. The bracket 2007 is installed in the box body 2001 and carries and fixes the GPU module 2009.
[0073] The functional element 2005 is mounted on the bracket 2007 through the buckling device 100 and is located on one side of the GPU module 2009. The functional element 2005 is used to guide the airflow flowing through the GPU module 2009 or other electronic control elements in the box 2001.
[0074] Please continue reading Figure 3 and Figure 4 The buckling device 100 includes a first body 10, a sliding member 30 and a buckle member 20. The first body 10 is formed on a bracket 2007.
[0075] In one embodiment, the number of the first body 10, the sliding member 30 and the buckle 20 is two respectively, and the two first bodies 10 are respectively located at opposite ends of the bracket 2007, but it is not limited thereto. Each first body 10, the sliding member 30 and the buckle 20 form a set. The sliding member 30 is located between the first body 10 and the buckle 20.
[0076] The buckle 20 is configured to connect the functional element 2005. The sliding member 30 is slidably connected to the first body 10. The buckle 20 is rotatably connected to the first body 10 and abuts against the sliding member 30. The buckle 20 is configured to drive the sliding member 30 to slide when rotating. When the sliding member 30 slides to the first setting position, the buckle 20 is buckled and connected to the first body 10. When the sliding member 30 is in the first setting position, it protrudes outside the box body 2001.
[0077] A force is applied to the functional element 2005 or the buckle 20 to rotate the buckle 20 . The buckle 20 is kept against the sliding member 30 during the rotation process. The sliding member 30 is forced to slide relative to the first body 10 .
[0078] In one embodiment, the functional element 2005 and the buckle 20 are integrally formed, but not limited thereto.
[0079] It can be understood that in other embodiments, the number of the first body 10, the sliding member 30 and the locking member 20 can also be one each.
[0080] The buckle device 100 is connected and fixed with the functional element 2005 through the buckle 20, and is rotatably connected to the first body 10. When the area near the functional element 2005 needs to be avoided, the buckle 20 is rotated to drive the functional element 2005 to rotate to expose the avoidance space, and the buckle 20 is buckled and connected to the first body 10, so that the buckle device 100 fixes the functional element 2005 to stably expose the avoidance space. The functional element 2005 does not need to be disassembled from the chassis 200, thereby avoiding the problem of missing the functional element 2005 when the chassis 200 is reassembled after avoidance. The sliding member 30 extends out of the box body 2001 and is visible outside the box body 2001 to remind the functional element 2005 that it is not installed in place.
[0081] It can be understood that in other embodiments, the first body 10 and the bracket 2007 may also be two independent structures, and the first bracket 2007 may also be directly connected to the inner wall of the box body 2001.
[0082] See also Figure 5 and Figure 6 In one embodiment, the box cover 2003 is connected to the box body 2001 and can hold and fix the sliding member 30. When the box cover 2003 is connected to the box body 2001, the sliding member 30 is held and fixed, thereby improving the position stability of the sliding member 30, and preventing the sliding member 30 or the buckle 20 from moving and damaging other structures in the box body 2001. Moreover, when the box cover 2003 is installed, the box cover 2003 moves toward the box body 2001 and applies pressure to the sliding member 30, so that the buckle 20 and the main body are released from the buckling connection. Even if the buckling device 100 is not restored to a closed state first, the position of the buckling device 100 in the box body 2001 can be restored by installing the box body 2001 at the same time, thereby avoiding the problem of reinstalling the buckling device 100 after the box body 2001 is installed because the position of the buckling device 100 is found to be wrong.
[0083] In one embodiment, when the box cover 2003 is connected to the box body 2001, the buckle 20 and the box cover 2003 are respectively pressed against the opposite ends of the sliding member 30, so that the sliding member 30 is stabilized at the second set position. The buckle device 100 also includes a second body 60. The second body 60 is fixed in the box body 2001, and the second body 60 is integrally formed with the first body 10, and the second body 60 is formed on a side wall of the bracket 2007. The first body 10 extends to one side of the second body 60, and two first bodies 10 are arranged at the two ends of the second body 60. When the box cover 2003 is connected to the box body 2001, the second body 60 is pressed against the buckle 20 to prevent the buckle 20 from rotating.
[0084] When the box cover 2003 is connected to the box body 2001 and the functional element 2005 is in the installed state, a stopper 2025 is provided on one side of the functional element 2005 facing the second body 60, and the stopper 2025 contacts the second body 60, so that the second body 60 stops the buckle 20 from rotating in the rotation direction of the buckle 20. When the box cover 2003 is detached from the box body 2001, the buckle 20 is rotated to separate the stopper 2025 from the second body 60.
[0085] The latch 20 and the box cover 2003 are abutted against the two ends of the sliding member 30, and the latch 20 is abutted by the second main body 60, that is, the second main body 60 and the box cover 2003 fixed relative to the box body 2001 are respectively abutted against the sliding member 30, so that the sliding member 30 and the latch 20 are fixed at the same time, ensuring the position stability of the fastening device 100 in the chassis 200.
[0086] It is understood that in other embodiments, the functional element 2005 may also be a fan 2010, a display adapter or an expansion card, etc. For example, in another embodiment, Fig.10 As shown, one of the two snap-fit devices 100 further includes a support member 70. The support member 70 connects the first bodies 10 of the two snap-fit devices 100. The fan 2010 is connected to the support member 70. When the fan 2010 needs to be evacuated, the snap member 20 is rotated and snapped on the first body 10, so that the sliding member 30 is located at the first position, the position of the fan 2010 is changed, and then the evacuation space is flowed out, and operations such as maintenance or disassembly of components in the box 2001 can be performed in the evacuation space.
[0087] In one embodiment, the support member 70 and the two first bodies 10 are an integrally formed structure, but the present invention is not limited thereto.
[0088] It is understandable that in other embodiments, the locking member 20 may be prevented from rotating by the support member 70 contacting the second body 60 .
[0089] The two snap fasteners 20 increase the strength of the snap-fit device 100 in supporting the functional element 2005, and increase the uniformity of the force supporting the functional element 2005, thereby increasing the position stability of the functional element 2005 and avoiding the problem of accidental damage to other components in the box 2001 due to unstable position of the functional element 2005.
[0090] See also Figure 7 and Figure 8 The buckling device 100 further includes a stopper 40. The sliding member 30 is provided with a slide groove 31. The stopper 40 is connected to the first body 10 after passing through the slide groove 31, and can slide in the slide groove 31.
[0091] It can be understood that in other embodiments, the limiting member 40 can also be disposed on the sliding member 30 , and the first body 10 is provided with the sliding groove 31 .
[0092] The buckle device 100 further includes a rotating shaft 50. The first body 10 and the buckle member 20 are rotatably connected via the rotating shaft 50. The rotating shaft 50 is offset from the sliding path of the sliding member 30.
[0093] The stopper 40 and the slide groove 31 are easy to manufacture and have a simple structure, and realize the sliding connection between the sliding member 30 and the first body 10. The rotating shaft 50 realizes the rotation connection between the first body 10 and the buckle 20. The rotating shaft 50 and the slide groove 31 are offset, and the sliding member 30 and the buckle 20 are spaced apart at the connection points where they are respectively connected to the first body 10, so that the buckle 20 and the sliding member 30 are conveniently connected to the first body 10 respectively.
[0094] In one embodiment, the slide groove 31 includes a first groove 311 and a second groove 313. The orthographic projection of the first groove 311 on the first body 10 is located inside the orthographic projection of the second groove 313 on the first body 10, and the first groove 311 is closer to the first body 10 than the second groove 313. The stopper 40 includes a connecting portion 41 and a stopper 43 connected. The connecting portion 41 is configured to pass through the first groove 311 and the second groove 313 and be connected to the first body 10, and the stopper 43 is located in the second groove 313 and stops at the side of the slide member 30 away from the first body 10.
[0095] The slide groove 31 is divided into a first groove 311 and a second groove 313 of different sizes, and the limiting member 40 is correspondingly provided with a connecting portion 41 and a limiting portion 43. The structure is simple and it is easy to realize that the limiting member 40 passes through the slide groove 31 and stops the sliding member 30 from leaving the side of the first body 10.
[0096] In one embodiment, there are a plurality of slide grooves 31 , which are disposed at intervals on the sliding member 30 . There are also a plurality of stoppers 40 , each of which is connected to the first body 10 and slidably disposed in one of the slide grooves 31 .
[0097] A plurality of slide grooves 31 are disposed at intervals on the sliding member 30 , and a solid structure is provided between adjacent slide grooves 31 , thereby improving the strength of the sliding member 30 .
[0098] It can be understood that in other embodiments, the number of the sliding groove 31 can also be one.
[0099] Please continue reading Figure 7 and Fig. 9 The buckle 20 is provided with a protruding abutting portion 23. The abutting portion 23 is spaced apart from the rotating shaft 50. A first arc surface 231 is provided on the peripheral side of the abutting portion 23. A second arc surface 315 is provided on the peripheral wall of the sliding member 30. The first arc surface 231 is in contact with and tangent to the second arc surface 315.
[0100] The outer peripheral walls of the abutting portion 23 and the sliding member 30 abut against and slide relative to each other, so that the locking member 20 rotates to drive the sliding member 30 to slide relative to the first body 10, and the outer periphery of the sliding member 30 contacts the outer periphery of the abutting portion 23, which is easy to achieve and improves the installation convenience of the abutting portion 23 and the sliding member 30.
[0101] In one embodiment, the first arc surface 231 is disposed at one end of the sliding member 30 close to the locking member 20 and is in the form of a semicircular surface. The supporting portion 23 is a cylindrical structure.
[0102] The first arc surface 231 is semicircular, and the abutting portion 23 is a cylindrical structure. The circular surface is easy to process and it is easy to ensure that the arc surface and the second arc surface 315 are tangent to each other, thereby improving the stability of the relative movement between the sliding member 30 and the locking member 20.
[0103] It can be understood that in other embodiments, the first arc surface 231 and the second arc surface 315 can also be omitted. For example, the supporting portion 23 is a rectangular block structure, and the supporting portion 23 contacts the outer peripheral wall of the sliding member 30. When the rotating member rotates, the supporting portion 23 pushes the sliding member 30 to make the sliding member 30 slide.
[0104] The sliding member 30 is located between the first body 10 and the buckle member 20. The buckle member 20 is provided with a buckle hole 25. The first body 10 is provided with a convex buckle 11. The convex buckle 11 is buckled and connected to the buckle hole 25. The convex buckle 11 is located on a side of the first body 10 facing the buckle member 20.
[0105] The buckle hole 25 is set on the buckle 20, and the protrusion 11 is set on the first body 10. The position of the protrusion 11 is fixed and will not move with the rotation of the buckle 20. There is no need to leave space between the sliding member 30 and the buckle 20 to avoid the protrusion 11, thereby reducing the distance between the sliding member 30, the buckle 20 and the first body 10.
[0106] The above-mentioned snap-fitting device 100 and the chassis 200 are connected and fixed with the functional element 2005 by the snap-fitting part 20, and are rotatably connected to the first main body 10. When the area near the functional element 2005 needs to be avoided, the snap-fitting part 20 is rotated to drive the functional element 2005 to rotate to expose the avoidance space. The functional element 2005 does not need to be disassembled from the case 2001, thereby avoiding the problem of missing the functional element 2005 when reassembling the chassis 200 after avoidance. The snap-fitting part 20 is snap-fitted and connected to the first main body 10, so that the snap-fitting device 100 fixes the functional element 2005 to stably expose the avoidance space, and the sliding part 30 extends out of the case 2001 and is visible outside the case 2001 to remind the functional element 2005 to be in the avoidance state.
