CROSS-REFERENCE TO RELATED APPLICATIONS

This non-provisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No(s). CN,202010478030.9 filed in China on May 29, 2020, the entire contents of which are hereby incorporated by reference.

TECHNICAL FIELD

This disclosure relates to a foolproof frame assembly and a server chassis, more particularly to a foolproof frame assembly having low-cost structural design and a foolproof component for achieving double foolproof protection and a server chassis including the foolproof frame assembly.

BACKGROUND

Nowadays, the configuration of electronic devices has become much more complicated, which makes the assembling process thereof has become much more complex, too. If one component is installed either in a wrong direction or a wrong place in an electronic device, it may result in malfunction of the electronic device. For example, if a fan module is installed in a wrong direction in the electronic device, heat generated in the electronic device cannot be effectively dissipated, and it may cause damage to the electronic device when in operation. Therefore, in order to prevent such situation from occurring, a foolproof mechanism is required.

The foolproof mechanism usually includes directional complementary structures respectively on the electronic device and components thereof, such that the electronic device and the components can be properly assembled, thereby preventing the increase of costs due to improper installation. Regarding the multiple steps of assembling process of the electronic device, improper installations in every step should all be avoided so as to ensure that the electronic device functions normally. However, if several additional foolproof structures or even additional assemblies having foolproof structures are added in order to ensure correct installation in every step of the assembling process, the manufacturing cost of the electronic device may increase. Take a fan module as an example, conventionally, in order to prevent the fan module from being installed in a wrong direction, two fan frames on opposite sides of the case of the electronic device are respectively provided with at least two different foolproof structures, such that the fan frames are required to be manufactured by different molds, thus increasing manufacturing cost of the electronic device. Therefore, how to obtain a balance between the design of foolproof structures and manufacturing cost of the electronic device while ensuring proper installation in every step of the assembly process is an important topic.

SUMMARY

The present disclosure is to provide a foolproof frame assembly and a server chassis including the same, which are capable of obtaining a balance between the design of foolproof structures and manufacturing cost of the electronic device while ensuring proper installation in every step of the assembly process.

One embodiment of the disclosure provides a foolproof frame assembly configured to be disposed on a case of a server chassis and configured for a mounting frame to be disposed thereon. The mounting frame includes a main body and two mounting side plates respectively protruding from two opposite sides of the main body. The foolproof frame assembly includes a first blocking component, a first frame, and a second frame. The first blocking component is configured to be fixed on the case. The first frame is configured to be disposed in a first mounting position located at one side of the case. The first frame includes a first bottom plate, two first side plates and a first foolproof component. The first bottom plate has two first through holes. The two first side plates are respectively connected to two opposite sides of the first bottom plate and both non-parallel to the first bottom plate. The first foolproof component is fixed to one of the two first side plates and blocks one of the two first through holes of the first bottom plate. When the first frame is disposed in the first mounting position, the first blocking component is disposed through the other of the two first through holes of the first bottom plate, and the first blocking component and the other of the two first side plates together form a first space configured for one of the two mounting side plates of the mounting frame to be disposed therethrough. The second frame is configured to be disposed in a second mounting position located at another side of the case opposite to the first mounting position. The second frame includes a second bottom plate, two second side plates and a second foolproof component. The second bottom plate has two second through holes. The two second side plates are respectively connected to two opposite sides of the second bottom plate and both non-parallel to the second bottom plate. The second foolproof component is fixed to one of the two second side plates and blocks one of the two second through holes of the second bottom plate. When the second frame is disposed in the first mounting position, a space occupied by the second foolproof component overlaps a space occupied by the first blocking component. When the first frame is disposed in the first mounting position and the second frame is disposed in the second mounting position, the first foolproof component and the second foolproof component are configured to block the two mounting side plates of the mounting frame so as to make one of the two mounting side plates disposed through the first space, and thus the mounting frame is maintained in a predetermined mounting position.

One embodiment of the disclosure provides a server chassis. The server chassis includes a case, a mounting frame, and a foolproof frame assembly. The mounting frame includes a main body and two mounting side plates respectively protruding from two opposite sides of the main body. The foolproof frame assembly includes a first blocking component, a first frame, and a second frame. The first blocking component is fixed on the case. The first frame is disposed in a first mounting position located at one side of the case. The first frame includes a first bottom plate, two first side plates and a first foolproof component. The first bottom plate has two first through holes. The two first side plates are respectively connected to two opposite sides of the first bottom plate and both non-parallel to the first bottom plate. The first foolproof component is fixed to one of the two first side plates and blocks one of the two first through holes of the first bottom plate. When the first frame is disposed in the first mounting position, the first blocking component is disposed through the other of the two first through holes of the first bottom plate, and the first blocking component and the other of the two first side plates together form a first space configured for one of the two mounting side plates of the mounting frame to be disposed therethrough. The second frame is disposed in a second mounting position located at another side of the case opposite to the first mounting position. The second frame includes a second bottom plate, two second side plates and a second foolproof component. The second bottom plate has two second through holes. The two second side plates are respectively connected to two opposite sides of the second bottom plate and both non-parallel to the second bottom plate. The second foolproof component is fixed to one of the two second side plates and blocks one of the two second through holes of the second bottom plate. When the second frame is disposed in the first mounting position, a space occupied by the second foolproof component overlaps a space occupied by the first blocking component. When the first frame is disposed in the first mounting position and the second frame is disposed in the second mounting position, the first foolproof component and the second foolproof component are configured to block the two mounting side plates of the mounting frame so as to make one of the two mounting side plates disposed through the first space, and thus the mounting frame is maintained in a predetermined mounting position.

According to the server chassis and the foolproof frame assembly thereof as described above, by disposing the first blocking component in the predetermined mounting position on the case corresponding to the first frame, and by the collaboration of the second foolproof component of the second frame, an unexpected installation of the second frame being disposed in the first mounting position is prevented, and thus an unexpected installation of the first frame being disposed in the second mounting position is also prevented. Furthermore, the first foolproof component and the second foolproof component are configured to block the mounting side plates of the mounting frame so as to make one of the mounting side plates disposed through the first space formed between the first blocking component and the first side plate, and thus the mounting frame is maintained in the predetermined mounting position, thereby realizing foolproof protection, preventing the heat dissipation fans in the mounting frame from being installed in a wrong direction, and ensuring that heat generated in the server device is effectively dissipated.

Furthermore, since the first bottom plate, the first side plates and the first support plates of the first frame have the same structure as that of the second bottom plate, the second side plates and the second support plates of the second frame, they can be manufactured by the same mold. Then, the first frame and the second frame, which are mirror-symmetrical to each other, can be formed by riveting the first foolproof component to the first side plate of the first sheet metal component and riveting the second foolproof component to the second side plate of the second sheet metal component. Therefore, the manufacturing cost of the server chassis can be reduced because there is no need to use different molds for manufacturing the first frame and the second frame.
