[0057] With technological advancements, especially the advent of the big data era, people are using more and more servers in their daily lives, performing increasingly diverse functions. Consequently, the demand for server development is increasing. Motherboard brackets are commonly used in servers to connect the motherboard to the server chassis and protect the motherboard from damage.

[0058] However, in the prior art, when the motherboard is assembled on the motherboard bracket, screws are usually used to fix the motherboard to prevent it from loosening.

Figure 11 This is the third structural diagram of the chassis provided in the embodiment of the present application.

[0069] like Figure 1 As shown, the motherboard bracket structure 100 provided in an embodiment of the present application is used in a chassis 200 of a server or the like. The motherboard bracket structure 100 includes a motherboard bracket 10, a core board 20, and an auxiliary board 30. The core board 20 and the auxiliary board 30 are respectively arranged on the motherboard bracket 10. The auxiliary board 30 is electrically connected to the core board 20.

[0070] The main board is designed to have a structure of a core board 20 and an auxiliary board 30 , and the core board 20 has a high reuse rate and compatibility, thereby reducing the development cost of the main board.

[0071] like Figure 3 As shown, the motherboard bracket 10 includes a bracket body 11 and a bracket side panel 14. The bracket side panel 14 is connected to the bracket body 11. The core board 20 and the auxiliary board 30 are respectively arranged on the bracket body 11. The bracket side panel 14 is used to connect the motherboard bracket 10 to the case 201 of the chassis 200.

[0072] A connecting component is provided between the mainboard bracket 10 and the core board 20 , and the core board 20 is connected to the mainboard bracket 10 via the connecting component and can slide relative to each other.

[0073] like Figure 4 As shown, in one possible implementation, the connection assembly includes a first connection column 12 and a first connection hole 21. The bracket body 11 is provided with the first connection column 12. The first connection column 12 is provided on a side of the bracket body 11 facing the core board 20. The first connection column 12 is used to connect the bracket body 11 and the core board 20.

[0074] The core board 20 is provided with a first connection hole 21 , which is corresponding to the first connection post 12 . The first connection hole 21 cooperates with the first connection post 12 to connect the core board 20 to the bracket body 11 .

[0075] The first connecting hole 21 is used for the first connecting column 12 to pass through, and the first connecting column 12 slides along the first connecting hole 21 so that the first connecting column 12 is snapped onto the first connecting hole 21 to connect the core board 20 to the bracket body 11 .

[0076] There are multiple first connecting columns 12, and the multiple first connecting columns 12 are arranged on the bracket body 11 around the outer periphery of the core board 20, so as to cooperate with the corresponding first connecting holes 21 to clamp the core board 20 to the bracket body 11 from the outer periphery of the core board 20.

[0077] In a possible implementation, the first connection hole 21 cooperates with the first connection column 12 to positionally connect the core board 20 to the bracket body 11 in the first direction x and the second direction y.

[0078] The second direction y is perpendicular to the first direction x.

[0079] A positioning assembly is provided between the mainboard bracket 10 and the core board 20 , and the core board 20 is positioned in a sliding position by the positioning assembly.

[0080] In one possible implementation, the positioning assembly includes a first positioning groove 111 and a first positioning post 22. The first positioning groove 111 is formed on the bracket body 11. The opening of the first positioning groove 111 faces the core board 20. The core board 20 is provided with a first positioning post 22. The first positioning post 22 is disposed corresponding to the first positioning groove 111. The first positioning post 22 cooperates with the first positioning groove 111 to position the core board 20 on the bracket body 11.

[0081] The first positioning post 22 is movably disposed in the first positioning slot 111 , thereby positioning the core board 20 on the bracket body 11 .

[0082] In a possible implementation, a first positioning column 22 and a first positioning groove 111 are provided, so that the core board 20 connected to the bracket body 11 through the action of the first connecting hole 21 and the first connecting column 12 is positioned on the bracket body 11.

[0083] In a possible implementation, the first positioning column 22 cooperates with the first positioning groove 111 to position the core board 20 on the bracket body 11 from the first direction x and the third direction z.

[0084] The third direction z is perpendicular to both the first direction x and the second direction y. The large surface of the bracket body 11 is located in a plane formed by the first direction x and the third direction z.

[0085] like Figure 2 and Figure 5 As shown, after the core board 20 is placed on the motherboard bracket 10, the first connecting column 12 passes through the first connecting hole 21. Subsequently, the core board 20 is moved along the extension direction of the first connecting hole 21, so that the first connecting column 12 slides in the first connecting hole 21 and is engaged with the first connecting hole 21, thereby connecting the core board 20 to the bracket body 11. When the core board 20 slides into place, the first positioning column 22 falls into the first positioning groove 111, positioning the slid core board 20 on the bracket body 11. At this time, the core board 20 and the motherboard bracket 10 are completely fixed, thereby realizing tool-free installation of the core board 20 and simple assembly steps.

[0086] In one possible implementation, the first connecting post 12 includes a connecting portion 121 and a limiting portion 122. The connecting portion 121 is disposed on the bracket body 11, and the limiting portion 122 is disposed on a side of the connecting portion 121 away from the bracket body 11. The connecting portion 121 is configured to pass through and slide within the first connecting hole 21. The limiting portion 122 is configured to prevent the first connecting post 12 from falling out of the first connecting hole 21.

[0087] The first connection hole 21 includes a connecting hole 211 and a sliding hole 212. The connecting direction of the connecting hole 211 and the sliding hole 212 is the extending direction of the first connection hole 21.

[0088] The communication direction between the through hole 211 and the sliding hole 212 is parallel to the third direction z.

[0089] Through-hole 211 allows the connection portion 121 and the stopper 122 to pass through, thereby positioning the stopper 122 and the bracket body 11 on opposite sides of the core board 20. Through-hole 211 also allows the connection portion 121 to slide along the direction of communication between through-hole 211 and the sliding hole 212. The sliding hole 212 restricts the passage of the stopper 122, thereby securing the stopper 122 to the side of the sliding hole 212 away from the bracket body 11.

[0090] During use, when the core board 20 is placed on the mainboard bracket 10, the limiting portion 122 first passes through the through-hole 211, and then the connecting portion 121 passes through the through-hole 211, so that the limiting portion 122 is located on the side of the core board 20 away from the bracket body 11. Subsequently, when the core board 20 moves along the extending direction of the first connecting hole 21, the connecting portion 121 slides along the extending direction of the first connecting hole 21 into the sliding hole 212, so that the limiting portion 122 moves from the side away from the bracket body 11 to the side of the sliding hole 212 away from the bracket body 11, thereby making the limiting portion 122 engage with the sliding hole 212, and connecting the core board 20 to the bracket body 11.

[0091] In the projection of the second direction y, the projection of the connecting portion 121 is located within the projection of the limiting portion 122 , that is, in the cross section formed by the first direction x and the third direction z, the cross-sectional area of ​​the connecting portion 121 is smaller than the cross-sectional area of ​​the limiting portion 122 .

[0092] In a possible implementation, a guide surface is provided on a side of the limiting portion 122 away from the connecting portion 121 .

[0093] The provision of the guide surface facilitates the insertion of the limiting portion 122 , thereby improving assembly efficiency.

[0094] In a possible implementation, the connecting portion 121 is cylindrical, and the limiting portion 122 is truncated cone-shaped.

[0095] In a possible implementation, the first connecting column 12 further includes a base 123 . The base 123 is disposed on the bracket body 11 , and the connecting portion 121 is disposed on a side of the base 123 away from the bracket body 11 .

[0096] The base 123 is cylindrical, and the diameter of the base 123 is larger than the diameter of the connecting portion 121 .

[0097] When the core board 20 is connected to the bracket body 11 , the base 123 and the limiting portion 122 are respectively located on both sides of the sliding hole 212 , thereby clamping the first connecting column 12 on the sliding hole 212 .

[0098] In a possible implementation, the through hole 211 and the sliding hole 212 are substantially gourd-shaped, so as to facilitate the sliding of the connecting portion 121 therein.

[0099] like Figure 7 As shown, in one possible implementation, the first positioning column 22 includes a sleeve 221, a positioning pin 222, and an elastic member. The sleeve 221 is provided on the core board 20, the positioning pin 222 is movably provided in the sleeve 221, and the elastic member is provided between the positioning pin 222 and the sleeve 221. The elastic member is used to push the positioning pin 222 out of the sleeve 221, so that the positioning pin 222 can be inserted into the first positioning groove 111 to position the core board 20.

[0100] In a possible implementation, a side of the positioning pin 222 away from the sleeve 221 is provided with a chamfer.

[0101] In a possible implementation, a chamfer is provided at the opening of the first positioning groove 111 .

[0102] The chamfered corners facilitate the fit between the positioning pin 222 and the first positioning groove 111, thus preventing the positioning pin 222 from becoming stuck.

[0103] In a possible implementation, the sleeve 221 is disposed on a side of the core board 20 away from the bracket body 11 , and the positioning pin 222 passes through the sleeve 221 and penetrates the core board 20 into the first positioning groove 111 .

[0104] In one possible implementation, the auxiliary board 30 includes a connecting board 31 and a functional board 32. The connecting board 31 and the functional board 32 are respectively provided on the bracket body 11. The connecting board 31 is electrically connected to the core board 20. The functional board 32 is connected to the side of the connecting board 31 away from the core board 20.

[0105] In a possible implementation, the connection board 31 may be a power distribution board (PDB).

[0106] In a possible implementation, the function boards 32 include a plurality of function boards 32 , and the plurality of function boards 32 are respectively connected to the connection board 31 .

[0107] In a possible implementation, the function board 32 may be a small board such as a baseboard management controller (BMC) or a network card (OCP) that provides different functions.

[0108] A second connecting assembly is provided between the motherboard bracket 10 and the connecting plate 31. Connecting plate 31 is connected to the motherboard bracket 10 via the second connecting assembly and can slide relative to it. The second connecting assembly works together with the first connecting assembly to connect the core board 20 and connecting plate 31 to the motherboard bracket 10, respectively. This reduces the relative movement between the core board 20 and connecting plate 31, thereby improving the stability of the electrical connection between the core board 20 and connecting plate 31.

[0109] like Figure 6 As shown, in one possible implementation, the second connecting assembly includes a second connecting post 13 and a second connecting hole 311. The bracket body 11 is provided with the second connecting post 13. The second connecting post 13 is provided on a side of the bracket body 11 facing the connecting plate 31. The second connecting post 13 is used to connect the bracket body 11 to the connecting plate 31.

[0110] The connecting plate 31 is provided with a second connecting hole 311 , which is corresponding to the second connecting post 13 . The second connecting hole 311 cooperates with the second connecting post 13 , thereby connecting the connecting plate 31 to the bracket body 11 .

[0111] The second connecting hole 311 is used for the second connecting post 13 to pass through, and the second connecting post 13 slides along the second connecting hole 311 so that the second connecting post 13 is engaged with the second connecting hole 311 to connect the connecting plate 31 to the bracket body 11 .

[0112] There are multiple second connecting columns 13, which are arranged on the bracket body 11 around the outer periphery of the connecting plate 31, so as to cooperate with the corresponding second connecting holes 311 to clamp the connecting plate 31 to the bracket body 11 from the outer periphery of the connecting plate 31.

[0113] In a possible implementation, the extending direction of the first connection hole 21 is not parallel to the extending direction of the second connection hole 311 .

[0114] In a possible implementation, the second connection hole 311 cooperates with the second connection column 13 to positionally connect the connection plate 31 to the bracket body 11 in the second direction y and the third direction z.

[0115] In a possible implementation, the second connecting pillar 13 has the same structure as the first connecting pillar 12 , thereby reducing the types of components.
