Description

Technical Field

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

[0002] A computer case typically includes the outer shell, bracket, and various switches and indicator lights on the front panel. As a component of a computer, the case's main function is to house and secure the various computer components, providing support and protection.

[0003] Existing chassis designs are generally designed primarily to address heat dissipation issues, resulting in a wide variety of chassis structures. However, most chassis on the market have motherboard trays that are fixed inside the chassis, requiring the chassis to be laid flat during CPU and memory installation. This is cumbersome and inconvenient due to the limited overall chassis frame area. Therefore, we propose an improved modular chassis structure. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a modular chassis structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular chassis structure, including a chassis frame, a motherboard tray inside the chassis frame, mounting blocks fixedly connected to the front end of the motherboard tray near the top and bottom, a fixing plate fixedly installed inside the chassis frame, two fixing plates in total, and mounting grooves opened at the rear ends of both fixing plates, the mounting blocks slidingly fitting into the mounting grooves, slots opened on both sides of the mounting blocks, and sliding grooves opened on both sides of the two mounting grooves, a locking block slidably connected in the sliding groove, the locking block slidingly fitting into the slot, and a spring fixedly connected between the locking block and the inner wall of the sliding groove, a pull rod fixedly connected to the side of the locking block away from the mounting block, the pull rod passing through the fixing plate, and the spring movably fitted onto the outer end of the pull rod.

[0006] By utilizing the above technical solution and the quick assembly / disassembly relationship between the mounting block and the fixing plate, the motherboard tray can be easily disassembled and assembled as needed, thereby facilitating the installation of the motherboard and its components during computer assembly.

[0007] As a further description of the above technical solution:

[0008] The upper end of the bottom plate of the chassis frame is fixedly connected to a power supply guard plate, and the fixing plate at the lower end is fixedly connected to the power supply guard plate.

[0009] With the above technical solution, the power supply protection plate usually does not have any special devices that occupy space, so it can be used to install a fixing plate.

[0010] As a further description of the above technical solution:

[0011] The top plate of the chassis frame has a fan slot, and a top heat dissipation mesh is provided on the fan slot. The fixing plate at the upper end is located on the lower end face of the fan slot near the rear side.

[0012] The above technical solution avoids conflicts between the fan slot's location and the mounting plate, thus preventing fan installation problems.

[0013] As a further description of the above technical solution:

[0014] The pull rod is fixedly connected to the outer wall of the rod body outside the fixed plate. The lower end of the fan slot and the upper end of the power supply guard plate are both fixedly connected to the limit plate. The limit plate has a limit groove, and the limit rod is movably sleeved into the limit groove.

[0015] By using the above technical solution, the limiting rod can be sleeved in the limiting groove, which can restrict the movement of the pull rod and thus prevent the block from moving under the pressure of the spring.

[0016] As a further description of the above technical solution:

[0017] The distance between the limiting rod and the limiting plate is greater than the movement distance of the block when it fully slides into the groove. One end of the pull rod passes through the limiting plate and is fixedly connected to a round cap.

[0018] The above technical solution ensures that when the limiting rod is inserted into the limiting groove, the locking block has completely entered the sliding groove and disengaged from the locking groove. The round cap structure allows for easy manual operation to move the lever.

[0019] As a further description of the above technical solution:

[0020] A lateral heat dissipation mesh is fixedly connected to one side of the chassis frame, and an auxiliary heat dissipation mesh is fixedly connected to the other side of the chassis frame. The lateral heat dissipation mesh and the auxiliary heat dissipation mesh are arranged opposite to each other.

[0021] The above technical solutions facilitate airflow and accelerate heat dissipation during chassis use.

[0022] As a further description of the above technical solution:

[0023] A glass door is rotatably connected to the front end of the chassis frame, and a rear cover plate is fixedly installed at the rear end of the chassis frame by bolts. A magnetic strip is fixedly connected to the outer wall of the glass door.

[0024] The above technical solution allows the glass door to be opened easily by rotating the connection, while the magnetic strips adsorb the metal chassis frame to ensure that the glass door can be closed stably.

[0025] As a further description of the above technical solution:

[0026] Both ends of the mounting block are made with a beveled structure, and the end of the locking block facing the rear end is also made with a beveled structure.

[0027] The above technical solution allows the mounting block to automatically press and retract into the sliding groove when the mounting block is in the mounting slot.

[0028] This utility model has the following beneficial effects:

[0029] 1. Compared with the existing technology, this modular chassis structure uses a combination of mounting blocks, slots, fixing plates, mounting grooves, sliding grooves, locking blocks, pull rods, and springs to work together. The mounting blocks fit into the mounting grooves, the locking blocks fit into the slots to fix them in place, and the pull rods can move the locking blocks to easily detach them from the mounting grooves. This allows the motherboard tray to be assembled and disassembled as needed, facilitating the installation of the motherboard and its components, making the process convenient and time-saving.

[0030] 2. Compared with the existing technology, this modular chassis structure, through the matching limit plate, limit groove and limit rod structure, can easily rotate the pull rod to make the limit rod engage in the limit groove to fix the position of the pull rod when disassembling the motherboard tray, and prevent the block from resetting under the spring pressure, thereby facilitating the disassembly of the motherboard tray.

[0038] Reference Figure 1-5 This utility model provides a modular chassis structure, including a chassis frame 1. A motherboard tray 2 is housed within the chassis frame 1. Mounting blocks 3 are fixedly connected to the front end of the motherboard tray 2 near its upper and lower ends. Two fixing plates 5 are fixedly installed inside the chassis frame 1, respectively, from the upper and lower ends of the motherboard tray 2. This makes the assembled structure more stable. Each of the rear ends of the two fixing plates 5 has a mounting groove 6, and the mounting blocks 3 are slidably fitted into the mounting grooves 6. Slots 4 are provided on both sides of the mounting blocks 3. Both sides of the mounting slot 6 are provided with sliding grooves 7, and a locking block 8 is slidably connected in the sliding groove 7. The locking block 8 is slidably fitted into the locking groove 4. By fitting the locking block 8 into the locking groove 4, the mounting block 3 can be fixed in the fixing plate 5, thereby facilitating the fixing of the main board tray 2. A spring 10 is fixedly connected between the locking block 8 and the inner wall of the sliding groove 7. A pull rod 9 is fixedly connected to the side of the locking block 8 away from the mounting block 3. The pull rod 9 is set through the fixing plate 5. The spring 10 is movably fitted on the outer end of the pull rod 9. By pulling the pull rod 9, the locking block 8 can be driven to disengage from the locking groove 4, thereby removing the mounting block 3 from the mounting slot 6.

[0039] Through the above technical solution, by utilizing the quick disassembly and assembly relationship between the mounting block 3 and the fixing plate 5, the motherboard tray 2 can be easily disassembled and assembled as needed, thereby facilitating the installation of the motherboard and its components during computer assembly.

[0040] The upper part of the bottom plate of the chassis frame 1 is fixedly connected to the power protection plate 101, and the fixing plate 5 located at the lower end is fixedly connected to the power protection plate 101. Under normal circumstances, there is no special device setting on the power protection plate 101 that would occupy space, so it can be used to set the fixing plate 5.

[0041] A fan slot is provided on the top plate of the chassis frame 1. A top heat dissipation mesh 102 is provided on the fan slot. The fixing plate 5 located at the upper end is located on the lower end face of the fan slot near the rear side to avoid conflict between the setting position of the fan slot and the fixing plate 5, which would cause problems with fan installation.

[0042] A limiting rod 13 is fixedly connected to the outer wall of the rod body of the pull rod 9 outside the fixed plate 5. A limiting plate 11 is fixedly connected to the lower end of the fan slot and the upper end of the power supply guard plate 101. A limiting groove 12 is opened on the limiting plate 11. The limiting rod 13 is movably sleeved in the limiting groove 12. Sleeving the limiting rod 13 in the limiting groove 12 can restrict the movement of the pull rod 9, thereby preventing the block 8 from moving under the pressure of the spring 10.

[0043] The distance between the limiting rod 13 and the limiting plate 11 is greater than the movement distance of the block 8 when it is fully slid into the groove 7. One end of the pull rod 9 passes through the limiting plate 11 and is fixedly connected with a round cap to ensure that when the limiting rod 13 is inserted into the limiting groove 12, the block 8 has fully entered the groove 7 and disengaged from the groove 4. The round cap structure allows for easy manual operation to pull the pull rod 9 to move.

[0044] A side heat dissipation mesh 103 is fixedly connected to one side of the chassis frame 1, and an auxiliary heat dissipation mesh 104 is fixedly connected to the other side of the chassis frame 1. The side heat dissipation mesh 103 and the auxiliary heat dissipation mesh 104 are arranged opposite to each other to facilitate airflow and accelerate heat dissipation during chassis use.

[0045] A glass door 105 is rotatably connected to the front end of the chassis frame 1, and a rear cover plate 106 is fixedly installed at the rear end of the chassis frame 1 by bolts. A magnetic strip 107 is fixedly connected to the outer wall of the glass door 105. The rotatable connection allows the glass door 105 to be opened easily, and the magnetic strip 107 can be used to attract the metal chassis frame 1 to ensure that the glass door 105 is closed stably.

[0046] Both ends of the mounting block 3 are made of beveled structure, and the end of the locking block 8 facing the rear end is also made of beveled structure, so that when the locking block 8 is in the mounting groove 6, the mounting block 3 can automatically press the locking block 8 into the sliding groove 7.

[0047] Working principle: In use, pull the lever 9 to move the locking block 8 out of the slot 4, and then rotate the lever 9 so that the limiting rod 13 is sleeved in the limiting groove 12, which can prevent the locking block 8 from resetting under the action of the spring 10. In this way, remove the four locking blocks 8 from the slot 4 in sequence, and the motherboard tray 2 can be removed to install the motherboard and the components on the motherboard. When wiring is required, align the mounting block 3 with the mounting groove 6 and push it into the predetermined position. Then rotate the lever 9 so that the limiting rod 13 disengages from the limiting groove 12. Then release the lever 9. Under the reset force of the spring 10, the locking block 8 will reset and re-lock into the slot 4, fixing the mounting block 3 in the fixing plate 5, thus completing the quick assembly of the motherboard tray 2, which is convenient and time-saving.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
