DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Embodiment 1

[0046] Reference Figure 1As shown, the PCIE module of the present invention includes a first cover plate 1 and a second cover plate 2, a first space 3 is arranged below the first cover plate 1, a second space 4 is arranged below the second cover plate 2, a first external plug-in card 5 is arranged in the first space 3, a second external plug-in card 6 is arranged in the second space 4, the second external plug-in card 6 is detachably plugged into the first external plug-in card 5, and the first cover plate 1 and the second cover plate 2 are hinged so that the second external plug-in card 6 can be taken out of or put into the second space 4.

[0047] The PCIE module of the present application can not only realize the expansion of PCIE cards, but also improve the maintenance efficiency of PCIE modules. Specifically, the PCIE module of the present application includes a first cover plate 1 and a second cover plate 2 which are hinged to each other, so the second cover plate 2 can be rotatably arranged relative to the first cover plate 1. Further, a first space 3 is arranged below the first cover plate 1, and a second space 4 is arranged below the second cover plate 2, the first space 3 is used to accommodate a first external card 5, and the second space 4 is used to accommodate a second external card 6. A first docking end 34 is arranged on the first external card 5, and the first docking end 34 is a slot, and a second docking end 35 is arranged on the second external card 6, and the second docking end 35 is a gold finger, and the first space 3 and the second space 4 are connected, so that the gold finger on the second external card 6 can be plugged into the slot on the second external card 6 to realize the communication connection and data transmission between the first external card 5 and the second external card 6, so that the second external card 6 can be directly expanded on the first external card 5, realizing the expansion of the external card (PCIE card). Among them, the first external card 5, the second external card 6 and the third external card 21 mentioned below are all PCIE cards, and the PCIE card includes a network adapter, a storage controller, an acceleration card and a graphics card, etc. Therefore, the user can expand the PCIE card with corresponding functions to the first external card 5 according to his actual needs, thereby realizing the expansion of the PCIE card. In addition, since the second cover plate 2 is hinged relative to the first cover plate 1, the second cover plate 2 can be rotatably arranged relative to the first cover plate 1, so that the user can take out or put in the second external card 6 from the second space 4 through the opened second cover plate 2, and the PCIE card can be expanded and replaced. In addition, the user can take out the second external card 6 from the second space 4, and maintain the cables inside the PCIE module with the help of the second space 4 without disassembling the entire PCIE module, thereby avoiding the disassembly steps of the entire PCIE module and effectively improving the maintenance efficiency of the PCIE module.

[0048] The PCIE module of the present application can directly plug the second external card 6 into the first external card 5, that is, the PCIE expansion card can be directly plugged into the first external card 5, thereby realizing the expansion of the PCIE card. Moreover, under the premise that the second cover plate 2 is rotatable relative to the first cover plate 1, the second external card 6 can be taken out or put in the second space 4, which not only realizes the expansion of the PCIE card, but also enables the cables inside the PCIE module to be maintained with the help of the second space 4 without disassembling the entire PCIE module, thereby avoiding the disassembly steps of the entire PCIE module and effectively improving the maintenance efficiency of the PCIE module.

[0049] In one embodiment, it also includes a hinge hinge 7, the hinge hinge 7 has a first hinge end 8 and a second hinge end 9, the first cover plate 1 is fixedly arranged, the first hinge end 8 is connected to the first cover plate 1, the second hinge end 9 is connected to the second cover plate 2, the second cover plate 2 opens or closes the second space 4, when the second space 4 is opened, the second external card 6 is taken out of or put into the second space 4.

[0050] like Figure 1 , Figure 2 , Figure 5 As shown, a hinge 7 is connected between the first cover plate 1 and the second cover plate 2 , and the hinge 7 is used to realize the rotation of the second cover plate 2 relative to the first cover plate 1 . Specifically, the hinge 7 has a hinge axis and a first hinge end 8 and a second hinge end 9 hinged to each other through the hinge axis, and the first hinge end 8 and the second hinge end 9 are both provided with a hinge through hole 36. The first cover plate 1 is fixedly arranged, and a first hinge threaded hole 37 is provided on the first cover plate 1. The hinge bolt passes through the hinge through hole 36 on the first hinge end 8 and cooperates with the first hinge threaded hole 37 to connect the first cover plate 1 with the first hinge end 8. Similarly, a second hinge threaded hole 66 is provided on the second cover plate 2. The hinge bolt passes through the hinge through hole 36 on the second hinge end 9 and cooperates with the second hinge threaded hole 66 to connect the second cover plate 2 with the second hinge end 9. Therefore, the second cover plate 2 rotates relative to the first cover plate 1 around the hinge axis through the hinge 7, so that the second cover plate 2 has an open state and a closed state. Furthermore, when the second cover plate 2 rotates relative to the first cover plate 1 around the hinge axis through the hinge 7 so that the second space 4 is exposed, the second cover plate 2 is in an open state. Figure 3As shown, at this time, the user can put the second external card 6 into the second space 4, and then plug the gold finger of the second external card 6 into the slot 13 of the first external card 5 in the second space 4 to achieve the communication connection between the first external card 5 and the second external card 6; in addition, the user can also unplug the second external card 6 from the first external card 5, and take the second external card 6 out of the second space 4, so that the user can maintain the cables inside the PCIE module. When the second cover plate 2 rotates relative to the first cover plate 1 around the hinge axis through the hinge 7 to close the second space 4, the second cover plate 2 is in a closed state, as shown in FIG. Figure 1 As shown, at this time, the PCIE module can work normally.

[0051] The PCIE module of the present application realizes the rotation of the second cover plate 2 relative to the first cover plate 1 through the hinge 7, so as to realize the opening and closing of the second space 4 through the rotation of the second cover plate 2, which not only realizes the expansion of the PCIE card, but also can maintain the cables inside the PCIE module with the help of the second space 4 without disassembling the entire PCIE module, thereby avoiding the disassembly steps of the entire PCIE module and effectively improving the maintenance efficiency of the PCIE module.
