Abstract

A chassis assembly includes a first frame and a second frame movably disposed on the first frame. At least one first connector is disposed on the first frame, and at least one second connector is disposed on the second frame, the connectors being positioned between the first and second frames. At least one magnetic element is positioned between the first and second frames, and at least one electromagnet assembly is positioned between the first and second frames in correspondence with the magnetic element. The electromagnet assembly includes a magnetic conductor and a coil wound around the magnetic conductor. In an unenergized state, magnetic attraction between the magnetic element and the magnetic conductor causes the first and second connectors to mate. In an energized state, magnetic repulsion between the magnetic element and the magnetic conductor causes the first and second connectors to separate.

Description

TECHNICAL FIELD The present disclosure relates to a chassis assembly, and more particularly to a chassis assembly that includes magnetic component. BACKGROUND Current server system configurations arrange numerous servers in an array within a server rack. Depending on their functions, the servers may include a variety of modules such as computing modules, power supply modules, storage drives, and liquid-cooling modules. To ensure sufficient cooling for the servers within the rack, at least one coolant distribution unit is usually included. When an operator attempts to install or remove components within the coolant distribution unit, a quick-release mechanism is typically employed to make the process easier. However, during installation or removal, the operator must exert significant force to position or disengage the internal components of the coolant distribution unit, increasing the difficulties of assembly and disassembly. Therefore, a challenge encountered by the R&D is to minimize the effort required to install and remove components within the coolant distribution unit, thereby enhancing the convenience of assembling and disassembling these units. SUMMARY The invention is as as defined in the appended claims. The present disclosure is directed to a chassis assembly that allows for more effortless installation and removal of a frame. An aspect of the present disclosure provides a chassis assembly. The chassis assembly includes a first frame, a second frame movably disposed on the first frame, at least one first connector and at least one second connector respectively disposed on the first frame and the second frame and located therebetween, at least one magnetic element located between the first frame and the second frame, and at least one electromagnet assembly located between the first frame and the second frame that corresponds to the magnetic element, the electromagnet assembly having a magnetic conductor and a coil that is wound around the magnetic conductor. When the electromagnet assembly is in an unenergized state, the at least one magnetic element and the magnetic conductor attract one another to cause the first connector and the second connector to mate. When the electromagnet assembly is in an energized state, the magnetic element and the magnetic conductor repel one another to cause the first connector and the second connector to separate. In some embodiments, the magnetic element is disposed on the first frame, and the electromagnet assembly is disposed on the second frame. In some embodiments, the electromagnet assembly further comprises a housing and a cover plate, the housing being disposed on the second frame, the magnetic conductor being located in the housing, the cover plate being disposed on the housing to enclose the magnetic conductor together with the housing, and the coil being wound around an area where the housing corresponds to the magnetic conductor. In some embodiments, the housing and the cover plate are made of plastic or a non-magnetic metal. In some embodiments, the first frame has at least one first positioning structure, the second frame has at least one second positioning structure, and the first positioning structure is configured to be disposed in the second positioning structure to align the first frame with the second frame. In some embodiments, the first positioning structure is a positioning protrusion, and the second positioning structure is a positioning hole.
