Description

Technical Field

[0001] This utility model belongs to the field of server chassis technology, specifically a server top cover positioning and locking structure. Background Technology

[0002] A server is a high-performance computer device that provides core functions such as computing power, data storage, and application services to client devices (such as computers and mobile phones) in a network environment. Compared to ordinary computers, servers have stronger processing power (such as multi-core CPUs or dedicated GPUs), larger capacity memory and storage, higher stability and scalability, and ensure reliable operation 24 / 7 through redundant design and cooling systems.

[0003] Most server covers on the market are single-plate structures. The cover is usually placed on the bottom of the server and then screwed on to the bottom of the server. However, this structure is not convenient to remove the cover for maintenance. The screws around the cover need to be loosened one by one, which is time-consuming and easy to miss. Especially in the scenario of densely deployed server racks, the efficiency of frequent maintenance is low. Utility Model Content

[0004] The purpose of this utility model is to provide a server top cover positioning and locking structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A server top cover positioning and locking structure includes a top cover plate connected to a server chassis, a fan module is provided inside the server chassis, a fixing pin is provided on the fan module, and a cover lock assembly that cooperates with the fixing pin is provided on the top cover plate.

[0007] The cover lock assembly includes a base and a handle. The upper end of the base has an opening, and a horizontally sliding plate is provided inside the base. The sliding plate has a pull hole, and the lower end of the base has a clearance hole corresponding to the position of the pull hole. A fixing pin passes through the clearance hole and is inserted into the pull hole. One end of the sliding plate has a connecting part with a movable hole. One end of the handle has a clearance position with a connecting shaft inserted into the movable hole. The two sides of the handle have symmetrical rotating shafts that are rotatably connected to the base. The sliding plate has a buckle, and a locking shaft is rotatably connected to the handle. The bottom of the locking shaft has a locking plate that cooperates with the buckle.

[0008] Furthermore, the handle is provided with an arc-shaped limiting block one, which is set at 90°, and the lower end of the lock shaft head is provided with an arc-shaped limiting block two, which is set at 180°. The other side of the arc-shaped limiting block two is a movable position, and the arc-shaped limiting block one is located within the movable position.

[0009] Furthermore, the upper end of the skateboard is provided with a protruding nail, and the lower end of the handle is provided with a steel wire that cooperates with the protruding nail. The steel wire is symmetrically bent and has an insertion space in the middle.

[0010] Furthermore, the inner sidewall of the base is symmetrically provided with limiting parts, which are located above the slide plate, with their lowest point slightly higher than the upper surface of the slide plate.

[0011] Furthermore, the upper cover plate has several pins on both sides, and the upper end of the side wall of the server chassis has several L-shaped grooves that cooperate with the pins.

[0012] Furthermore, the fan module includes a base frame fixedly connected to the two side walls of the server chassis and two fixing blocks. A pad is installed in the center of the base frame, and the fixing pin is set on the pad. The pad has a slot 1 on both sides. The base frame has an upward extension on both sides. The two extensions abut against the corresponding fixing blocks. Each of the two extensions has a slot 2 corresponding to the position of slot 1. Two fan brackets are installed on the base frame. The two fan brackets are respectively set on both sides of the pad. Each of the two fan brackets has an elastic piece 1 on its side wall. The outer side of each elastic piece 1 has a plug for inserting into slot 1 or slot 2.

[0013] Furthermore, the server chassis has several Y-shaped slots on both sides, and Y-shaped plugs are inserted into the Y-shaped slots. The Y-shaped plugs are integrally formed with the air guide shroud and are set on both sides of the air guide shroud. The air guide shroud has a concave structure. The interior of the protruding part of the air guide shroud is the air duct, and the concave part of the air guide shroud is the capacitor placement area. The capacitor placement area is provided with a capacitor limiting structure, and the top of the air guide shroud is provided with a PCB board placement slot.

[0014] Furthermore, the capacitor limiting structure includes limiting protrusions one located on both sides of the capacitor placement area, and elastic sheet two located at the bottom of the capacitor placement area. The elastic sheet two is provided with limiting protrusions two, and the capacitor placement area is provided with vent holes below the two limiting protrusions one.

[0015] The beneficial effects of this utility model are:

[0016] This invention utilizes a method where pressing down on the handle allows it to fully embed into the base. The movement of the handle causes the sliding plate to slide away from the fixing pin. When the handle is fully pressed down, a screwdriver is used to rotate the locking shaft, causing the locking shaft and locking plate to rotate synchronously. This locks the locking plate under the inverted clip, preventing the handle from being lifted upwards and achieving a secure connection between the top cover and the server chassis. The top cover cannot be directly pushed out. To unlock, simply use a screwdriver to rotate the locking shaft in the opposite direction, causing the locking plate to separate from the inverted clip. Then, lift the handle, allowing the sliding plate to slide towards the fixing pin, thus releasing the lock and allowing the top cover to be pushed out. The entire process eliminates the need for multiple screws for fixing, greatly simplifying maintenance and improving work efficiency.

[0017] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please refer to Figure 1-9 ;

[0030] A server cover positioning and locking structure includes a top cover plate 2 connected to a server chassis 1. A fan module 3 is housed inside the server chassis 1, and a fixing pin 6 is provided on the fan module 3. A cover locking assembly 4, which cooperates with the fixing pin 6, is provided on the top cover plate 2. The cover locking assembly 4 includes a base 41 and a handle 42. The base 41 is fixedly connected to the top cover plate 2. An opening is provided at the upper end of the base 41, and a horizontally sliding slide plate 43 is provided inside the base 41. A pull hole 431 is provided on the slide plate 43, and a clearance hole 411 corresponding to the position of the pull hole 431 is provided at the lower end of the base 41. The fixing pin 6 passes through the clearance hole 411 and is inserted into the pull hole 431. When the top cover plate 2 is installed, the fixing pin 6 on the fan module 3 is inserted into the pull hole 431 through the clearance hole 411 to achieve positioning of the top cover plate 2. A connecting part 43 is provided at one end of the slide plate 43. 2. The connecting part 432 is provided with a movable hole 433. One end of the handle 42 is provided with a clearance 421. The clearance 421 is provided with a connecting shaft 422 that is inserted into the movable hole 433. The two sides of the handle 42 are symmetrically provided with rotating shafts 423 that are rotatably connected to the base 41. The rotating shafts 423 and the connecting shafts 422 are arranged parallel to each other. When the handle 42 is rotated, the handle 42 will rotate along the rotating shafts 423. When the handle 42 is rotated, the connecting shafts 422 will push the slide plate 43. The slide plate 43 is provided with a buckle 435. The handle 42 is provided with a locking shaft 424. The bottom of the locking shaft 424 is provided with a locking plate 425 that cooperates with the buckle 435. When the locking shaft 424 is rotated, the locking shaft 424 drives the locking plate 425 to rotate together, so that the upper end face of the locking plate 425 abuts against the lower end face of the protruding part of the buckle 435, thereby locking the cover lock assembly 4.

[0031] Working principle: First, place the top cover 2 over the server chassis 1, ensuring that the fixing pin 6 is aligned with the clearance hole 411 and the pull hole 431. Then, press down on the handle 42 until it is fully embedded in the base 41. The movement of the handle 42 causes the sliding plate 43 to slide away from the fixing pin 6. Once the handle 42 is fully pressed down, use a screwdriver to rotate the locking shaft 424, causing the locking shaft 424 and the locking plate 425 to rotate synchronously. This locks the locking plate 425 under the inverted clip 435, preventing the handle 42 from being lifted upwards. This achieves a secure connection between the top cover 2 and the server chassis 1, preventing the top cover 2 from being directly pushed out. To unlock, simply use a screwdriver to rotate the locking shaft 424 in the opposite direction, causing the locking plate 425 to disengage from the inverted clip 435. Then, lift the handle 42, causing the sliding plate 43 to slide towards the fixing pin 6, releasing the lock and allowing the top cover 2 to be pushed out. The entire process eliminates the need for multiple screws, greatly simplifying maintenance and improving work efficiency.

[0032] To address the issue of excessive rotation angles caused by the inability to observe the position of the locking plate 425 when rotating the locking shaft 424, resulting in misalignment between the locking plate 425 and the snap fastener 435, this embodiment provides an arc-shaped limiting block 427 on the handle 42, with the arc-shaped limiting block 427 set at 90°. An arc-shaped limiting block 428 is provided at the lower end of the head of the locking shaft 424, with the arc-shaped limiting block 428 set at 180°. The other side of the arc-shaped limiting block 428 is a movable position 429, within which the arc-shaped limiting block 427 is located. This limits the rotation angle of the locking shaft 424 to within 90 degrees, ensuring that the locking shaft 424 and the locking plate 425 can be accurately rotated to the locking position, allowing the locking plate 425 to align and engage with the snap fastener 435, thereby locking the upper cover plate 2 and preventing locking failure due to excessive rotation.

[0033] In this embodiment, the upper end of the slide plate 43 is provided with a protruding nail 434, and the lower end of the handle 42 is provided with a steel wire 426 that cooperates with the protruding nail 434. The steel wire 426 is symmetrically bent and has an insertion space in the middle. When the handle 42 is closed, the protruding nail 434 on the slide plate 43 will extend into the insertion space in the middle of the steel wire 426. At this time, the two sides of the bent steel wire 426 will clamp the protruding nail 434 and lock the handle 42. Even if the locking plate 425 is not engaged with the buckle 435, the handle 42 will not open arbitrarily, which increases the reliability of use.

[0034] In this embodiment, a limiting part 412 is symmetrically provided on the inner side wall of the base 41. The limiting part 412 is located above the slide plate 43, and its lowest end is slightly higher than the upper surface of the slide plate 43, ensuring that the slide plate 43 can only slide horizontally.

[0035] In this embodiment, the upper cover plate 2 is provided with a plurality of pins 21 on both sides, and the upper end of the side wall of the server housing 1 is provided with a plurality of L-shaped grooves 11 that cooperate with the pins 21. After the pins 21 are placed in the L-shaped grooves 11, the upper cover plate 2 is slid so that the pins 21 are located at the end of the horizontal section of the L-shaped grooves 11, thereby fixing the upper cover plate 2 in the upper and lower directions. With the cooperation of the cover lock assembly 4, the server cover is completely locked.

[0036] In this embodiment, the fan module 3 includes a base frame 31 fixedly connected to the two side walls of the server chassis 1 and two fixing blocks 32. A pad 33 is installed in the center of the base frame 31, and a fixing pin 6 is set on the pad 33. Slot 1 34 is provided on both sides of the pad 33. An upward extension 35 is provided on both sides of the base frame 31. The two extensions 35 abut against the corresponding fixing blocks 32 respectively. Each of the two extensions 35 is provided with a slot 2 36 corresponding to the position of slot 1 34. Two fan brackets 37 are installed on the base frame 31. The two fan brackets 37 are respectively set on both sides of the pad 33. Each of the two side walls of the two fan brackets 37 is provided with an elastic piece 38. The outer side of the elastic piece 38 is provided with a plug block 39 for inserting into slot 1 34 or slot 2 36. When installing the fan bracket 37, simply insert the fan bracket 37 downwards. Since the plug-in block 39 protrudes from the outer wall of the fan bracket 37, when the plug-in block 39 contacts the extension 35 and the pad block 33, it will squeeze the elastic sheet 38, causing it to temporarily bend into the fan bracket 37. As the fan bracket 37 continues to be inserted, when it reaches the correct position, several plug-in blocks 39 are aligned with the corresponding slot 34 and slot 36 respectively. At this time, the elastic sheet 38 returns to its original state, and the plug-in block 39 and the plug-in block 39 are inserted into the slot 34 and slot 36 respectively to complete the quick installation of the fan bracket 37.

[0037] In this embodiment, the server housing 1 has several Y-shaped slots 12 on both sides, and Y-shaped plugs 51 are inserted into the Y-shaped slots 12. The Y-shaped plugs 51 are integrally formed with the air guide shroud 5 and are located on both sides of the air guide shroud 5. During installation, the Y-shaped plugs 51 on the air guide shroud 5 are simply aligned and inserted into the Y-shaped slots 12 of the server housing 1 to achieve quick installation of the air guide shroud 5. The air guide shroud 5 has a concave structure. The interior of the protruding part of the air guide shroud 5 is an air duct for air circulation, and the concave part of the air guide shroud 5 is a capacitor placement area 52 for placing capacitors. The capacitor placement area 52 is provided with a capacitor limiting structure for fixing the capacitors. The top of the air guide shroud 5 is provided with a PCB board placement slot 53 for placing PCB circuit boards.

[0038] In this embodiment, the capacitor limiting structure includes limiting protrusions 521 located on both side walls of the capacitor placement area 52, and an elastic sheet 522 located at the bottom of the capacitor placement area 52, with limiting protrusions 523 on the elastic sheet. When installing the capacitor, the lower end face of the capacitor first contacts the limiting protrusion 523 and applies pressure to it, causing the elastic sheet 522 to bend downwards. As the capacitor continues to be installed, when it reaches a predetermined position, the upper end of the capacitor contacts the lower end face of the limiting protrusion 521, thereby restricting the movement of the capacitor in the vertical direction. Furthermore, due to the reduced pressure on the capacitor, the elastic sheet 522 returns to its original shape, allowing the limiting protrusion 523 to abut against one end of the capacitor. The cooperation with the side walls of the capacitor placement area 52 effectively restricts the movement of the capacitor in the horizontal direction, ensuring the stability of the capacitor installation. The capacitor placement area 52 is located below the two limiting protrusions 521 and is provided with ventilation holes 524. Air can enter through the ventilation holes 524 to effectively dissipate heat from both sides of the capacitor.
