Description

Technical Field

[0001] This invention belongs to the field of computer servers, and in particular relates to a computer server chassis structure. Background Technology

[0002] Most existing computer server chassis adopt a one-piece or simple split structure. When maintaining, replacing, or upgrading internal circuit boards, hard drives, or other components, it is usually necessary to open the side panel of the chassis, which limits operating space and is cumbersome. Some server chassis with pull-out designs require separate actions for securing (such as tightening screws) and pushing in when pushing internal modules back into the chassis, failing to provide a quick "push-in and lock" installation experience. Furthermore, exposed handles or locking mechanisms are susceptible to accidental bumps or misoperation during transportation or daily use. Summary of the Invention

[0003] In view of this, the present invention aims to propose a computer server chassis structure, so as to overcome the technical problems of inconvenient maintenance and complicated installation and locking operations of server chassis in the prior art.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows: A computer server housing structure includes an inner housing and an outer housing. The inner housing is inserted into the end opening of the outer housing. The inner housing includes an end face and a mounting housing. A snap-fit ​​positioning component is provided between the end face and the inner wall of the outer housing. The snap-fit ​​positioning component is used to position the end face onto the outer housing. A handle is rotatably provided on the end face. An unlocking component is provided on the handle. When the handle is flipped open, the handle flips and triggers the unlocking component, causing the unlocking component to disengage from the snap-fit ​​positioning component.

[0005] Furthermore, the snap-fit ​​positioning assembly includes two first connecting frames and two pairs of snap-fit ​​seats. The first connecting frame includes a first vertical plate and two first horizontal plates. The two first vertical plates are fixedly connected to both ends of the back side of the end face body. The ends of the two first horizontal plates on the same first connecting frame are provided with snap-fit ​​claws. An elastic support is provided between the snap-fit ​​claws and the first horizontal plates. The two pairs of snap-fit ​​seats are respectively fixedly connected to both sides of the inner wall of the outer casing. The two snap-fit ​​seats in the same pair are symmetrically arranged with reference to the first connecting frame. The end of the snap-fit ​​seat has a guide slope. The surface of the snap-fit ​​seat is provided with a snap-fit ​​groove. The surface of the snap-fit ​​claw has a snap-fit ​​block. The snap-fit ​​block and the snap-fit ​​groove are engaged for snap-fit.

[0006] Furthermore, the front of the end face is provided with an opening, a storage shell is fixedly connected inside the opening, a rotating shaft is rotatably connected inside the storage shell, and the handle is fixedly connected to the surface of the rotating shaft.

[0007] Furthermore, the unlocking component includes two connecting rods, which are fixedly connected to both ends of the rotating shaft. The two connecting rods extend through the mounting housing and out of the mounting housing. An elliptical cam is provided at the end of each connecting rod away from the rotating shaft, and the two proximal ends of the cams contact two locking claws respectively.

[0008] Furthermore, a track assembly is provided between the mounting housing and the inner wall of the outer casing. The track assembly includes two slide rails and two pairs of rotating shafts. The two slide rails are respectively fixedly connected to both sides of the inner wall of the outer casing. The slide rails include clearance slots and connecting cavities. The two pairs of rotating shafts are respectively fixedly connected to both sides of the mounting housing. Rollers are rotatably connected to both pairs of rotating shafts. The rollers are rolled within the connecting cavities. The clearance slots provide movement space for the rotating shafts. A limiting groove is fixedly connected to the bottom of the inner wall of the connecting cavity, and the rollers roll within the limiting groove.

[0009] Furthermore, an elastic limiting device is provided at the rear end of the connecting cavity. The elastic limiting device includes a connecting seat, which is fixedly connected to the rear end of the connecting cavity. Two elastic telescopic rods are fixedly connected to the surface of the connecting seat, and a limiting baffle is fixedly connected to the ends of the two elastic telescopic rods. The limiting baffle has an arc-shaped limiting surface.

[0010] Furthermore, the latching claw includes a first horizontal segment, a first vertical segment, and a second horizontal segment. The first horizontal segment is fixedly connected to the latching block, and the second horizontal segment contacts the proximal end of the cam. An arc-shaped groove is provided on the second horizontal segment facing the cam.

[0011] Furthermore, the elastic support includes two support rods and two connecting holes. The two support rods are fixedly connected to the surface of the second horizontal section, and the two connecting holes are opened on the surface of the first horizontal plate. After the two support rods pass through the two connecting holes, they are inserted into the first horizontal plate. Support springs are sleeved on the surface of each of the two support rods, and the two ends of the support springs are fixedly connected to the first horizontal plate and the second horizontal section, respectively.

[0012] Furthermore, a plug-in prism is fixedly connected to one end of the connecting rod near the cam, and a plug-in through slot adapted to the plug-in prism is opened on the surface of the cam. A threaded rod is fixedly connected to the end of the plug-in prism, and a fastening nut is threaded onto the surface of the threaded rod.

[0013] Furthermore, the handle includes a first flip frame, which is fixedly connected to the surface of the rotating shaft. A grip is rotatably connected to the top of the first flip frame, and a magnet is fixedly connected to the bottom of the inner wall of the storage shell.

[0014] Compared with the prior art, the computer server chassis structure of the present invention has the following advantages: (1) The computer server housing structure described in this invention can be unlocked by flipping the handle in a single action. Then the inner housing can be pulled out directly for maintenance without any tools, which significantly improves the efficiency of server maintenance. After maintenance, the inner housing only needs to be pushed back along the track. The locking and positioning component can automatically complete the precise alignment and locking under the action of the guide slope and elastic element, realizing the lock when pushed in. The installation process is simple and reliable.

[0015] (2) The computer server housing structure described in this invention allows the handle to be completely stored in the storage groove of the end face, avoiding external protrusion, saving space, and preventing accidental collision during transportation and use.

[0016] (3) The computer server housing structure described in this invention, with the track assembly and the elastic limiting device at the rear end, not only ensures the smooth and stable pulling process, but also provides elastic pre-tightening after full insertion, thereby enhancing the stability and impact resistance of the overall connection.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 10 As shown, in one embodiment, a computer server housing structure includes an inner housing 2 and an outer housing 1. The inner housing 2 is inserted into the end opening of the outer housing 1. The inner housing 2 includes an end face 21 and a mounting housing 22. A snap-fit ​​positioning component 3 is provided between the end face 21 and the inner wall of the outer housing 1. The snap-fit ​​positioning component 3 is used to position the end face 21 on the outer housing 1. A handle 4 is rotatably provided on the end face 21. An unlocking component 5 is provided on the handle 4. During the process of flipping the handle 4 open, the handle 4 flips and triggers the unlocking component 5, so that the unlocking component 5 releases the snap-fit ​​positioning component 3.

[0024] Specifically, the end face 21 is also provided with an external interface 211 for inserting signal lines such as optical cables and electrical cables, and is located above the handle 4.

[0025] The mounting housing 22 is also fixedly connected to a positioning frame 23. The positioning frame 23 has a slot for mounting circuit boards or other devices. The mounting housing 22 and the outer casing 1 have a first port 221 and a second port 11 on their backs, respectively, and the external wiring terminals provide clearance channels.

[0026] When maintenance or installation of circuit boards or other components inside a computer server is required, the handle 4 can be flipped. During the flipping process, the unlocking component 5 will release the locking and positioning component 3, allowing the inner casing 2 to be pulled out from the outer casing 1. After maintenance, the handle 4 can be flipped back and stored. Then, the inner casing 2 can be directly inserted into the outer casing 1. The locking and positioning component 3 will automatically lock the end face 21 with the outer casing 1, making the installation convenient and quick.

[0027] The snap-fit ​​positioning assembly 3 includes two first connecting frames 31 and two pairs of snap-fit ​​seats 34. The first connecting frame 31 includes a first vertical plate 311 and two first horizontal plates 312. The two first vertical plates 311 are fixedly connected to both ends of the back side of the end face body 21. The ends of the two first horizontal plates 312 on the same first connecting frame 31 are provided with snap-fit ​​claws 32. An elastic support member 33 is provided between the snap-fit ​​claws 32 and the first horizontal plates 312. The two pairs of snap-fit ​​seats 34 are respectively fixedly connected to both sides of the inner wall of the outer casing 1. The two snap-fit ​​seats 34 in the same pair are symmetrically arranged with reference to the first connecting frame 31. The end of the snap-fit ​​seat 34 has a guide slope 341. The surface of the snap-fit ​​seat 34 is provided with a snap-fit ​​groove 342. The surface of the snap-fit ​​claw 32 has a snap-fit ​​block 324. The snap-fit ​​block 324 cooperates with the snap-fit ​​groove 342 to snap-fit. During the process of pushing the inner casing 2 into the outer casing 1, the mounting housing 22 will first enter from the end opening of the outer casing 1. During the process of the end face 21 aligning with the end opening of the outer casing 1, the ends of the two locking claws 32 will respectively interact with the guide slopes 341 at the ends of the two locking seats 34. Under the action of the guide slopes 341, the two locking claws 32 will move away from each other. When the locking block 324 moves to the locking groove 342 under the action of the locking claws 32, the locking claws 32 will drive the locking block 324 to form a locking with the locking groove 342 under the action of the elastic support 33. This achieves automatic locking and positioning during the process of aligning the inner casing 2 with the outer casing 1, without the need for other positioning operations, which is convenient and quick.

[0028] The front of the end face 21 has an opening, and a storage shell 212 is fixedly connected inside the opening. A rotating shaft 41 is rotatably connected inside the storage shell 212, and the handle 4 is fixedly connected to the surface of the rotating shaft 41. The storage shell 212 allows the handle 4 to be flipped and folded inside the storage shell 212, preventing it from protruding from the end face 21 and occupying external space.

[0029] Specifically, the two ends of the rotating shaft 41 pass through the storage shell 212 and extend to the outside of the storage shell 212, and the two end surfaces of the rotating shaft 41 are fixedly connected with limit rings 411. The two limit rings 411 are located on both sides of the storage shell 212 to form a limit.

[0030] The unlocking component 5 includes two connecting rods 51, which are fixedly connected to both ends of the rotating shaft 41. The two connecting rods 51 pass through the mounting housing 22 and extend to the outside of the mounting housing 22. Each connecting rod 51 has an elliptical cam 52 at its end away from the rotating shaft 41. The two proximal ends of the cam 52 contact the two locking claws 32. When the handle 4 is flipped open from its folded state, the rotating shaft 41 synchronously drives the connecting rods 51 to rotate, which in turn drives the cams 52 to rotate. The distal end of the cam 52 gradually approaches the locking claws 32, pushing the two locking claws 32 and causing the locking block 324 to disengage from the locking groove 342, thus releasing the locking mechanism. The distal end of the cam 52 and the locking claws 32 form a support, maintaining the unlocked state. Pulling the handle 4 directly will pull the inner casing 2 and outer casing 1 out.

[0031] The locking claw 32 includes a first horizontal segment 321, a first vertical segment 322, and a second horizontal segment 323. The first horizontal segment 321 is fixedly connected to the locking block 324. The second horizontal segment 323 contacts the proximal end of the cam 52. An arc-shaped groove 3231 is provided on the second horizontal segment 323 facing the cam 52. During the process of flipping the handle 4 from the folded state to open, the cam 52 pushes the second horizontal segment 323 of the locking claw 32 until the distal end of the cam 52 contacts the second horizontal segment 323. At this time, the arc-shaped groove 3231 will fit against the distal end of the cam 52, limiting the state of the cam 52. This helps to limit the handle 4 after it is flipped open, maintaining the contact and locking state while providing support for the operator to operate the handle 4. When the handle 4 is pushed to fold by external force, the cam 52 can overcome the limitation of the arc-shaped groove 3231 and flip out from the arc-shaped groove 3231.

[0032] The elastic support member 33 includes two support rods 331 and two connecting holes 3121. The two support rods 331 are fixedly connected to the surface of the second horizontal section 323, and the two connecting holes 3121 are formed on the surface of the first horizontal plate 312. The two support rods 331 pass through the two connecting holes 3121 and are inserted into the first horizontal plate 312. A support spring 332 is sleeved on the surface of each of the two support rods 331, and the two ends of the support spring 332 are fixedly connected to the first horizontal plate 312 and the second horizontal section 323, respectively. The function of the elastic support spring 332 and the support rods 331 is to connect the two locking claws 32 to the first connecting frame 31 and maintain elastic support, providing the possibility for the cam 52 to push the locking claws 32.

[0033] like Figure 2 , Figure 8 , Figure 9 and Figure 10As shown, in one embodiment, a track assembly 6 is provided between the mounting housing 22 and the inner wall of the outer casing 1. The track assembly 6 includes two slide rails 61 and two pairs of rotating shafts 62. The two slide rails 61 are respectively fixedly connected to both sides of the inner wall of the outer casing 1. The slide rails 61 include a clearance slot 611 and a connecting cavity 612. The two pairs of rotating shafts 62 are respectively fixedly connected to both sides of the mounting housing 22. Rollers 63 are rotatably connected to both pairs of rotating shafts 62. The rollers 63 are rolled in the connecting cavity 612. The clearance slot 611 provides movement space for the rotating shafts 62. A limiting groove 613 is fixedly connected to the bottom of the inner wall of the connecting cavity 612. The rollers 63 roll in the limiting groove 613. During the process of inserting the inner casing 2 into the outer casing 1, the roller 63 will dock with the slide rail 61. The roller 63 will roll in the limiting groove 613, so that the roller 63 can maintain a stable trajectory on the slide rail 61. On the one hand, it connects the inner casing 2 and the outer casing 1 and provides support. On the other hand, it provides the conditions for the snap-fit ​​positioning component 3 to dock with the end face 21 and the outer casing 1.

[0034] Specifically, the slide rail 61 is located between two locking seats 34 on one side of the inner wall of the mounting housing 22.

[0035] An elastic limiting device 64 is provided at the rear end inside the connecting cavity 612. The elastic limiting device 64 includes a connecting seat 641, which is fixedly connected to the rear end inside the connecting cavity 612. Two elastic telescopic rods 642 are fixedly connected to the surface of the connecting seat 641. Limiting baffles 643 are fixedly connected to the ends of the two elastic telescopic rods 642. The limiting baffles 643 have arc-shaped limiting surfaces.

[0036] When the inner casing 2 is fully pushed in and locked in place, the roller 63 rests precisely against the arc-shaped limiting surface of the limiting baffle 643. The elastic telescopic rod 642 is slightly compressed, providing a forward elastic preload. This force is transmitted to the end face 21 through the roller 63 and the mounting housing 22, making the engagement of the locking block 324 and the locking groove 342 more tight and reliable. This provides support for the docking of the inner casing 2 and the outer casing 1. Furthermore, when the end face 21 is subjected to external pressure, the elastic telescopic rod 642 can retract, providing the roller 63 with a degree of freedom to move and buffering unexpected impacts from the direction of the end face 21, thus reducing damage to the end face 21.

[0037] like Figure 10 As shown, there is a space between the locking claw 32 and the end of the slide rail 61 to provide a buffer space.

[0038] like Figure 6 and Figure 7As shown, in one embodiment, a plug-in prism 511 is fixedly connected to one end of the connecting rod 51 near the cam 52. A plug-in slot 521 adapted to the plug-in prism 511 is formed on the surface of the cam 52. A threaded rod 512 is fixedly connected to the end of the plug-in prism 511, and a fastening nut 7 is threaded onto the surface of the threaded rod 512. The cam 52 is plugged into the plug-in prism 511 through the plug-in slot 521, and then the fastening nut 7 is threaded onto the threaded rod 512, thus limiting the movement of the cam 52 and completing the connection between the cam 52 and the connecting rod 51.

[0039] The handle 4 includes a first flip frame 42, which is fixedly connected to the surface of the rotating shaft 41. A grip 43 is rotatably connected to the top of the first flip frame 42, and a magnet 2121 is fixedly connected to the bottom of the inner wall of the storage shell 212. The grip 43 is made of magnetic metal.

[0040] During the process of folding the handle 4, the operation handle 4 flips and folds the first flip frame 42 into the inside of the storage shell 212, and the grip 43 is also folded with the first flip frame 42, so that the bottom end of the grip 43 contacts the magnet block 2121. The magnet block 2121 magnetically attracts the grip 43, keeping the handle 4 stable in the folded state inside the storage shell 212, ensuring that the handle 4 will not accidentally pop open when not in use, keeping the end face clean, and during the installation of the cam 52, it can support the rotating shaft 41 and the connecting rod 51, providing a stable environment for the docking of the cam 52.

[0041] Working principle: Installation procedure: The maintenance personnel align the inner casing 2 with the opening of the outer casing 1 and push it in along the track assembly 6. At the end of the push-in, the guide ramp 341 of the locking positioning assembly 3 guides the locking claw 32 to move and automatically engage with the locking groove 342, completing the locking. The roller 63 contacts and compresses the elastic limiting device 64, providing a stable preload. At this time, the handle 4 is in the retracted state.

[0042] Disassembly procedure: The maintenance personnel flip the handle 4 upwards. The rotation of the handle 4 triggers the cam 52 of the unlocking component 5, pushing open the locking claw 32, causing the locking block 324 to disengage from the locking groove 342, thus releasing the lock. The distal end of the cam 52 engages with the arc-shaped slot 3231 for temporary restraint. The maintenance personnel can then directly grasp the flipped-out handle 4 and easily pull the inner casing 2 completely out of the outer casing 1 along the track.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
