As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0030] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0031] This invention provides a universal card mounting structure, primarily used on the motherboard in a server chassis as a fixing device for cards connected to the motherboard via a connector. The invention is described below through specific embodiments, where the card used is an OCP card.

[0032] like Figure 1 , 2 As shown in Figure 3, the universal card mounting structure includes a first locking structure 1 and a second locking structure 2 arranged opposite to each other. The first locking structure 1 includes a fixed member 12 and a movable member 11. The movable member 11 is mounted on the fixed member 12 and can rotate in the circumferential direction and move in the axial direction along the fixed member 12. A positioning structure is also provided between the fixed member 12 and the movable member 11. The positioning structure includes at least two positioning holes 123 on the fixed member 12 and a positioning protrusion 113 on the movable member 11 that positions and cooperates with the positioning holes 123. When the positioning protrusion 113 is placed in different positioning holes 123, the movable member 11 forms different fixing angles relative to the fixed member 12.

[0033] The first clamping structure 1 and the second clamping structure 2 are arranged in relative spacing, the OCP card 100 is installed between the first clamping structure 1 and the second clamping structure 2, the second clamping structure 2 can adopt the same structure as the first clamping structure 1, or can adopt the fixing structure of the OCP card 100 on the market at present, and the ultimate purpose of the first clamping structure 1 and the second clamping structure 2 is to clamp the two sides of the OCP card 100 by mutual cooperation.

[0034] The OCP card 100 has two installation modes, one is an OCP card 100 reverse installation mode, and the other is a transverse sliding insertion installation mode, wherein the OCP card 100 reverse installation mode is suitable for the case that the mainboard 200 can only adopt a vertical interface, and the transverse sliding insertion mode is suitable for the case that the mainboard 200 can only adopt a horizontal interface. As shown in Figure 4 Figure 4 It is shown that the OCP card 100 adopts a transverse sliding insertion installation mode, so during installation, the fixed part 12 and the movable part 11 are adjusted to a parallel state. As shown in Figure 5 Figure 5 It is shown that the OCP card 100 adopts a reverse installation mode, so during installation, the fixed part 12 and the movable part 11 are adjusted to a vertical state.

[0035] The angle of the fixed part 12 and the movable part 11 can be switched at will, so it can be compatible with multiple installation modes of the OCP card 100, which is beneficial to the modular design of the mainboard 200, reduces the development cost of parts, and is more convenient to maintain.

[0036] As shown in Figures 1-3 The fixed part 12 is provided with two positioning holes 123, and the fixed part 12 is provided with a positioning protrusion 113; when the positioning protrusion 113 is placed in one of the positioning holes 123, the movable part 11 and the fixed part 12 are in a vertical state, and when the positioning protrusion 113 is placed in the other positioning hole 123, the movable part 11 and the fixed part 12 are in a parallel state. Figure 4 The movable part 11 and the fixed part 12 are in a parallel state, Figure 5 The movable part 11 and the fixed part 12 are in a vertical state.

[0037] Of course, in other embodiments, the positioning hole 123 and the positioning protrusion 113 can be installed in the opposite positions, that is, the positioning hole 123 is arranged on the movable part 11, and the positioning protrusion 113 is arranged on the fixed part 12.

[0038] It should be noted that the number of positioning holes 123 can be set according to requirements, of course, in most cases, two positioning holes 123 can be set, and of course, if there is a special requirement, the positioning hole 123 can be designed as three or four.

[0039] ​​In one embodiment, the fixing member 12 has a first cut along its axial direction, and the movable member 11 has a second cut along its axial direction. When the movable member 11 and the fixing member 12 are parallel, the first cut and the second cut together form a card slot that cooperates with the card. When the OCP card 100 is installed, the side of the OCP card 100 is embedded in the card slot, and the card slot plays a limiting role for the OCP card 100.

[0040] Of course, in some embodiments, the movable member 11 does not have a second cut, but instead forms a slot directly through the combination of the surface area of ​​the movable member 11 and the first cut.

[0041] In one embodiment, such as Figure 1 , 2 As shown in Figure 3, the fixed member 12 is provided with a rotating shaft mounting groove 121, and the movable member 11 is provided with a rotating shaft connecting part 111 placed in the rotating shaft mounting groove 121. The rotating shaft mounting groove 121 is provided with an elastic member 124 for applying elastic force to the rotating shaft connecting part 111. The rotating shaft mounting groove 121 is also provided with a positioning hole 123, and the rotating shaft connecting part 111 is provided with a positioning protrusion 113. When there is no external force, the elastic member 124 is in an extended state, and the positioning protrusion 113 is pressed tightly in the positioning hole 123 under the elastic force of the elastic member 124. When the rotating shaft connecting part 111 is subjected to an external force in the direction of compressing the elastic member 124, the elastic member 124 is compressed so that the positioning protrusion 113 can be disengaged from the positioning hole 123.

[0042] The function of the elastic element 124 is to ensure that the positioning protrusion 113 is pressed tightly into the positioning hole 123, so as to prevent the positioning protrusion 113 from detaching from the positioning hole 123 when there is no external force, thus affecting the change of the fixed angle state.

[0043] In this embodiment, the elastic element 124 is a compression spring.

[0044] In one embodiment, such as Figure 1 , 2, 3, the rotating shaft mounting groove 121 includes a first end and a second end opposite to the first end, the first end of the rotating shaft mounting groove 121 is provided with an elastic connecting hole 125, the second end of the rotating shaft mounting groove 121 extends to the first end of the rotating shaft mounting groove 121 and is provided with a shaft rod part 122; the elastic part 124 includes a first end and a second end, the first end of the elastic part 124 is arranged in the elastic connecting hole 125; the rotating shaft connecting part 111 is extended and provided with an embedding part 112 on the side close to the second end of the elastic part 124, the rotating shaft connecting part 111 is provided with a shaft hole 114 on the side close to the shaft rod part 122, the second end of the elastic part 124 is sleeved on the embedding part 112, and the shaft rod part 122 is embedded in the shaft hole 114. The positioning protrusion 113 is arranged on the side of the rotating shaft connecting part 111 close to the shaft rod part 122, and the positioning hole 123 is arranged on the end face of the second end of the rotating shaft mounting groove 121. The positioning hole 123 is arranged around the shaft rod part 122.

[0045] The combination of the shaft hole 114 and the shaft rod part 122 makes the movable part 11 rotate more smoothly relative to the fixed part 12, and avoids jamming.

[0046] In an embodiment, the edge of the middle part of the movable part 11 is provided with an inner recess, and the inner recess is arranged to facilitate an operator to hold the inner recess with fingers to rotate the movable part 11.

[0047] In actual installation and use, since the OCP card 100 has two installation modes of reverse installation mode and sliding insertion installation mode, the installation process is also different.

[0048] In the reverse installation mode, first, the movable part 11 is rotated to be perpendicular to the fixed part 12, and the positioning protrusion 113 and the positioning hole 123 cooperate to form positioning at this angle, then the OCP card 100 is inserted into the connector of the mainboard 200 from top to bottom, after the connection is completed, finally, the movable part 11 is rotated to be horizontal to the fixed part 12, and the positioning protrusion 113 and the positioning hole 123 cooperate to form positioning at this angle, and the installation is completed.

[0049] In the sliding insertion installation mode, the movable part 11 is directly rotated to be horizontal to the fixed part 12, and the positioning protrusion 113 and the positioning hole 123 cooperate to form positioning at this angle, then the OCP card 100 is transversely inserted and connected with the connector of the mainboard 200, and the installation is completed after the connection is completed.

[0050] The embodiment of the present application also provides a mainboard 200, which comprises a board body and a universal card mounting structure arranged on the board body.

[0051] In some embodiments, in order to facilitate disassembly and installation, the universal card mounting structure is detachably connected to the plate body through the provided connecting structure. Specifically, the connecting structure includes a connecting rod and a threaded seat threadedly connected with the connecting rod, the fixing member 12 is provided with a connecting groove, the plate body is provided with a through hole at a position corresponding to the connecting groove, the connecting rod is arranged in the connecting groove and the through hole, the lower end of the connecting rod is connected through the threaded seat located at the bottom of the plate body, the connecting groove includes a front groove section and a rear groove section, the width of the front groove section is greater than the width of the top end face of the connecting rod and less than the width of the rear groove section. When the connecting rod is in the front groove section and the threaded seat is tightened, the front groove section forms a limiting relationship with the top end face of the connecting rod, thereby fixing the fixing member 12 on the plate body, when the connecting rod is in the rear groove section, whether the threaded seat is tightened or not, the rear groove section does not form a limiting relationship with the top end face of the connecting rod, so that the fixing member 12 can be disassembled from the plate body without obstacles.

[0052] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
