Description

Technical Field

[0001] The utility model belongs to the technical field of computers, and particularly relates to an extended cabinet for a server. Background Art

[0002] A server cabinet is an essential key component in a data center, designed specifically to support and protect server hardware. It is made of sturdy metal materials to cope with various complex environments and challenges, ensuring the stable operation of the server. The internal layout of the server cabinet is reasonable, supporting high-density hardware installation. At the same time, it is equipped with an efficient heat dissipation system, such as fans, heat sinks, etc., to handle the heat generated during high-load operation and ensure the stable and reliable performance of the server. In addition, the chassis design usually takes into account ease of maintenance, such as convenient disassembly structures and easy-to-operate maintenance windows, making hardware replacement, upgrade, and fault troubleshooting more convenient. With the rapid development of technologies such as cloud computing and big data, the demand for server cabinets is increasing continuously, providing a solid hardware foundation for modern data centers.

[0003] However, in the prior art, the internal space of the server cabinet is of a fixed volume, and it is not convenient for subsequent space expansion when additional server devices need to be added. Summary of the Utility Model

[0004] To solve the problem that the internal space of the server cabinet cannot meet the requirements after adding server devices, the utility model provides an extended cabinet for a server.

[0005] The utility model is realized through the following technical solutions:

[0006] An extended cabinet for a server includes a main chassis with open structures on a pair of opposite sidewalls. An extended chassis is slidably arranged in the main chassis, and there are openings on a pair of opposite sidewalls of the extended chassis; several layers of bases are arranged in the extended chassis, and a space expansion mechanism is arranged in the bases; the space expansion mechanism includes a receiving cavity and a reinforcing plate. The opening of the receiving cavity faces the side that slides out of the extended chassis towards the outside of the main chassis. An extended plate is slidably arranged in the receiving cavity. A first threaded groove is formed on the extended plate, and a first threaded lead screw that is rotationally connected to the base and can drive the extended plate in and out of the receiving cavity is fitted in the first threaded groove; the reinforcing plate is arranged in the main chassis to cooperatively support the extended plate that slides out of the receiving cavity.

[0007] When the extended chassis slides out of the main chassis towards the outside, the overall internal space of the cabinet is increased; by rotating the first threaded lead screw, the extended plate is pushed to horizontally move outwards along the receiving cavity, and the extended plate that extends out cooperates with the base as a bearing surface for carrying the server; with the support of the reinforcing plate, the extended plate is supported at the end away from the base to enhance the stability of the server device.

[0008] A further improvement of the present utility model is that at one end of the extension board that slides away from the extension chassis towards the outside of the main chassis, there is a support and stability mechanism. The support and stability mechanism includes at least one set of telescopic strip groups. Each telescopic strip group includes two telescopic strips that are slidably arranged on the extension board. The sliding direction of the telescopic strips is perpendicular to the sliding direction of the extension board in the horizontal plane. On the inner wall of the main chassis, there are also fixed holes that can be adapted to the telescopic strips to fix the extension board in its moving direction. By sliding out the telescopic strips on both sides of the extension board and cooperating with the fixed holes on the inner wall of the main chassis, it helps to fix the extension board in the horizontal plane.

[0009] A further improvement of the present utility model is that the above-mentioned support and stability mechanism further includes a guide groove for the telescopic strips to slide. At the inner end of the telescopic strip, a second threaded lead screw for driving the telescopic strip to move is rotatably provided. At the end of the second threaded lead screw away from the telescopic strip, there is a driven bevel gear. Between the two driven bevel gears, there is a common meshing driving bevel gear. At the axis of the driving bevel gear, there is a transmission rod extending towards the outside of the extension board in the horizontal plane. The thread directions of the two second threaded lead screws in the same telescopic strip group are opposite. The driving bevel gear meshes with the two driven bevel gears for transmission, realizing the second threaded lead screw to push the telescopic strip to slide along the guide groove, thereby realizing the convenient operation of telescoping the telescopic strip on the extension board by operating the driving bevel gear.

[0010] A further improvement of the present utility model is that in the above-mentioned guide groove, there is a second bearing for supporting the rotation of the second threaded lead screw, and the second bearing is arranged close to the driven bevel gear. The stability of the rotation of the second threaded lead screw is realized through the second bearing.

[0011] A further improvement of the present utility model is that openings on the side of the main chassis facing the open side of the accommodation cavity and openings on the side of the extension chassis facing away from the open side of the accommodation cavity are respectively provided with cabinet doors. On the cabinet doors, there are fan assemblies for cooling the internal equipment. The air circulation inside is realized through two relatively arranged fan assemblies to improve the heat dissipation effect.

[0012] A further improvement of the present utility model is that the above-mentioned fan assembly includes a heat dissipation frame penetrating the cabinet door. Inside the heat dissipation frame, there is a mounting seat. On the mounting seat, there is a motor, and a heat dissipation blade is connected to the output shaft of the motor.

[0013] A further improvement of the present utility model is that on the above-mentioned heat dissipation frame, there is also a filter screen outside the heat dissipation blade. The filter screen filters the impurities in the air flowing through the inside of the cabinet, which helps to reduce the influence of impurities on the server equipment.

[0014] A further improvement of the present utility model is that on the above-mentioned cabinet door, there is also a transparent glass window for observing the inside. It can timely check the operation of the internal server equipment.

[0015] A further improvement of the present utility model is that the inner bottom surface of the main chassis is provided with a concave slideway, and the bottom surface of the expansion chassis is provided with a slide rail that cooperates with the slideway. The slide rail moves outwards along the slideway, realizing the guiding of the expansion chassis moving along the main chassis while reducing the moving resistance.

[0016] A further improvement of the present utility model is that the main chassis is provided with a positioning member that can fix the expansion chassis. When the expansion chassis is retracted into the main chassis or pulled out of the main chassis, the positioning member can act on the expansion chassis to realize the locked state of the expansion chassis relative to the main chassis.

[0017] As can be seen from the above technical solutions, the beneficial effects of the present utility model are as follows: when the expansion chassis slides out of the main chassis to the outside, the overall internal space of the cabinet is increased; by rotating the first threaded lead screw, the expansion board is pushed to move horizontally outwards along the accommodation cavity, and the extended expansion board cooperates with the base as the bearing surface for carrying the server; the extended expansion board is supported at one end away from the base by the support of the reinforcing board to enhance the stability of the server equipment.
