[0004] However, in the above method, when it is necessary to maintain the adapter board component, it is necessary to remove the above 2 screws, take out the PCIe card and the adapter board component together from the chassis before the adapter board component can be maintained; it is impossible to directly take out only the adapter board component from the chassis, resulting in a more complicated disassembly process; moreover, since the PCIe card needs to be taken out together, it will affect other operations of the chassis. Summary of the Utility Model

[0005] The embodiments of this application provide a component structure and a chassis applied to a PCIe card to achieve the effect of conveniently disassembling the adapter board component.

[0006] In a first aspect, the embodiments of this application provide a component structure applied to a PCIe card, including: a pressing piece and at least one connecting component, and the connecting component includes a PCIe card, an adapter board component and a U-shaped part.

[0007] Among them, the closed end of the U-shaped part is fixedly connected to the side wall of the chassis; the PCIe card is inserted into the side wall of the chassis, and the tongue of the PCIe card is inserted into the open end of the U-shaped part; the pressing piece presses the tongue of the PCIe card, and the pressing piece is screwed to the side wall of the chassis.

[0008] The adapter board component is snap-connected to the U-shaped part, and the adapter board component and the U-shaped part are fixedly connected by a first screw.

[0009] In a possible implementation manner, the second plate of the U-shaped part fits against the side wall of the chassis, and a positioning pin is provided on the first plate of the U-shaped part.

[0010] A positioning hole is provided on the adapter board component; the U-shaped part is snap-connected to the positioning hole through the positioning pin.

[0011] In a possible implementation, a first screw hole is provided on the first plate of the U-shaped part; a second screw hole is provided on the adapter plate assembly; a first screw passes through the second screw hole and the first screw hole to fixedly connect the adapter plate assembly and the U-shaped part.

[0012] In a possible implementation, the sum of the thickness of the tongue of the PCIe card and the thickness of the pressing piece is less than or equal to the width of the open end of the U-shaped part.

[0013] In a possible implementation, the closed end of the U-shaped part is snap-connected to the side wall of the chassis; alternatively, the closed end of the U-shaped part is screwed to the side wall of the chassis through a second screw.

[0014] In a possible implementation, a T-shaped hole is provided on the adapter plate assembly; a T-shaped screw is fixedly provided on the upper cover of the chassis.

[0015] The T-shaped screw passes through the T-shaped hole to connect the upper cover of the chassis and the adapter plate assembly.

[0016] In a possible implementation, a connection groove is provided on the side wall of the chassis, and the PCIe card is inserted into the connection groove.

[0017] In a possible implementation, the length of the pressing piece is less than or equal to a first preset value, the first preset value is the sum of the width of the connection groove and a preset spacing distance, and the preset spacing distance is the distance width between adjacent connection grooves on the side wall of the chassis.

[0018] In a possible implementation, the length of the pressing piece is equal to the width of the side wall of the chassis.

[0019] In a second aspect, the present application provides a chassis, and the component structure as described in any item of the first aspect is provided in the chassis.

[0020] In a possible implementation, a bottom support for supporting the PCIe card is provided on the lower side of the chassis.

[0021] For the component structure and the chassis applied to the PCIe card provided in the embodiments of the present application, after the adapter plate assembly is snap-connected to the upper surface of the first plate of the U-shaped part and locked with the U-shaped part through the first screw; therefore, when it is necessary to disassemble the adapter plate assembly, only the first screw needs to be unlocked, and then the adapter plate assembly can be taken out for maintenance. Compared with the prior art where two screws need to be unlocked to disassemble the adapter plate assembly, in the present application, only one first screw needs to be unlocked to disassemble the adapter plate assembly, which simplifies the process of disassembling the adapter plate assembly, thereby reducing the workload of the staff for disassembly and maintenance and improving work efficiency.

[0022] In addition, in the present application, the PCIe card is fixed to the chassis through pressing and U-shaped parts; and the adapter board assembly is fixed to the U-shaped parts. Therefore, when the adapter board assembly needs to be disassembled, although the PCIe card is inserted into the groove of the adapter board assembly, the force that fixes the PCIe card to the chassis is greater than the frictional force between the PCIe card and the groove of the adapter board assembly. Therefore, during the process of pulling out the adapter board assembly, the PCIe card 5 will not be taken out by the adapter board assembly but will continue to be fixed inside the chassis. Furthermore, the separate removal of the adapter board assembly is achieved, and the staff does not need to remove the PCIe card again after removing the adapter board assembly, thus simplifying the maintenance work of the adapter board assembly and achieving the effect of conveniently disassembling the adapter board assembly.

[0060] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0061] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0062] In order to meet the needs of data storage, high-performance computing, etc., a server is needed. The structure of a server includes: motherboard, central processing unit (CPU), random access memory (RAM), hard disk drive (HDD; solid state drive, SSD), power supply unit (PSU) and chassis, etc.

[0063] For the server motherboard, in order to expand the functional requirements of the motherboard, one or more PCIe cards need to be plugged into the motherboard as a function expansion. For example, a PCIe card can be used as a graphics processing unit (GPU), a network interface card (NIC), etc.

[0064] In order to plug a PCIe card into a motherboard, the PCIe card needs to be plugged into a PCIe adapter assembly (e.g., an adapter board assembly), and then the PCIe adapter assembly is inserted into a PCIe slot of the motherboard, thereby realizing the expansion function of the PCIe card. Therefore, it is necessary to fix the PCIe card and the adapter board assembly in the chassis.

[0065] In an example, Figure 1 The PCIe card 1 shown includes a PCIe card body 11, a gold finger 12 disposed above the PCIe card body 11, and a tongue 13 disposed on the side of the PCIe card body 11. The gold finger 12 is used for electrical connection between the PCIe card 1 and the motherboard to allow data transmission between the PCIe card 1 and the motherboard.

[0066] like Figure 2 The fixing method shown involves the connection between the PCIe card 1 , the adapter board assembly 2 , and the chassis 3 .

[0067] The chassis 3 includes side walls 31 and a bottom plate 32, wherein the number of the side walls 31 is four. Figure 2 Only one of the side walls 31 is shown.

[0068] Along the height direction of the PCIe card body 11, one or more connection grooves 33 are formed on the side wall 31. The width of the connection groove 33 is adapted to the thickness of the PCIe card body 11, so that the side of the PCIe card 1 can be installed into the connection groove 33. After the side of the PCIe card 1 is installed into the connection groove 33, the tongue 13 is located above the side wall 31, and the bottom of the PCIe card 1 is located above the bottom plate 32 of the chassis 3.

[0069] A groove (not shown in the figure) is formed in the adapter board assembly 2. The gold finger 12 is inserted into the adapter board assembly 2 through the groove of the adapter board assembly 2 to realize the assembly of the PCIe card 1 and the adapter board assembly 2.

[0070] The adapter board assembly 2 includes a first connection board 21 and a second connection board 22. Screw holes are formed on both the first connection board 21 and the second connection board 22. Two screws are respectively connected to the two side walls 31 of the chassis through the screw holes formed in the first connection board 21 and the second connection board 22; thus, the fixed connection between the adapter board assembly 2 and the two side walls 31 is realized.

[0071] However, the problem with the above fixing method is that during the use of the server, daily maintenance of the adapter board assembly 2 is involved, which requires the adapter board assembly 2 to be disassembled regularly.

[0072] During the disassembly process of the adapter board assembly 2, the staff needs to unlock the screws in the first connection board 21 and the second connection board 22 in sequence before the adapter board assembly 2 can be taken out. Moreover, since the gold finger 12 of the PCIe card 1 is inserted into the adapter board assembly 2, when the staff takes out the adapter board assembly 2, the PCIe card 1 will also be taken out together.

[0073] Therefore, combining the above scenarios, it can be seen that the existing fixing method brings inconvenience to the staff for disassembling and maintaining the adapter board assembly.

[0074] The component structure and chassis applied to the PCIe card provided in the present application are used to solve the above technical problems.

[0075] The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0076] Figure 3 Schematic explosion structure of a component structure applied to a PCIe card provided by the present application Figure 1 as Figure 3As shown, the component structure includes:

[0077] A pressing piece 4 and at least one connecting component, the connecting component including a PCIe card 5, an adapter board component 6, and a U-shaped piece 7.

[0078] Wherein, the closed end of the U-shaped piece 7 is fixedly connected to the side wall 31 of the chassis 3; the PCIe card 5 is inserted into the side wall 31 of the chassis 3, and the tongue 53 of the PCIe card 5 is inserted into the open end of the U-shaped piece 7; the pressing piece 4 presses the tongue 53 of the PCIe card 5, and the pressing piece 4 is screwed to the side wall 31 of the chassis 3.

[0079] The adapter board component 6 is snap-connected to the U-shaped piece 7, and the adapter board component 6 and the U-shaped piece 7 are fixedly connected by a first screw 61.

[0080] Exemplarily, the component structure includes a pressing piece 4 and at least one connecting component; wherein, the connecting component includes a PCIe card 5, an adapter board component 6, and a U-shaped piece 7.

[0081] First, the fixation between the PCIe card 5 and the chassis 3 is introduced.

[0082] The U-shaped piece 7 is disposed on the upper surface of the side wall 31. The U-shaped piece 7 includes a closed end and an open end, and the closed end of the U-shaped piece 7 is fixedly connected to the upper surface of the side wall 31. The U-shaped piece 7 includes a first plate member 71, a second plate member 72, and a rotating shaft 73 passing between the first plate member 71 and the second plate member 72, such that the first plate member 71 can rotate relative to the second plate member 72 about the rotating shaft 73; wherein, the plane in which the rotational movement of the first plate member 71 lies is parallel to Figure 3 the plane in which the PCIe card 5 is in the installation state shown.

[0083] For example, according to the positional relationship between the first plate member 71 and the second plate member 72 of the U-shaped piece 7, the U-shaped piece 7 can be divided into two position states. Among them, the first position state of the U-shaped piece 7 is that the first plate member 71 is at 90° relative to the second plate member 72, and the second position state of the U-shaped piece 7 is that the first plate member 71 is parallel to the second plate member 72; in the first position state, the U-shaped piece 7 is in an unlocked state, and in the second position state, the U-shaped piece 7 is in a locked state. The U-shaped piece 7 in the locked state can play a role in fixing the components between the first plate member 71 and the second plate member 72 of the U-shaped piece 7.

[0084] The PCIe card 5 includes a PCIe card main body 51, a gold finger 52 disposed at the upper end of the PCIe card main body 51, and a tongue 53 disposed at the upper end of the side surface of the PCIe card main body 51 (i.e., the surface corresponding to the width direction of the PCIe card 5); when observing the PCIe card 5 from the front, the tongue 53 is in an inverted "L" shape.

[0085] The PCIe card 5 is inserted into the side wall 31 of the chassis 3 along its thickness direction, that is, the PCIe card body 51 is inserted into the side wall 31 of the chassis 3 along its thickness direction, thereby realizing the preliminary fixation between the PCIe card 5 and the chassis 3; after the PCIe card 5 is installed in place in the side wall 31, the tongue 53 is inserted into the open end of the U-shaped member 7, that is, the first plate member 71 is rotated to a position where it is at a 90° angle to the second plate member 72, so that the U-shaped member 7 is in the first position state, and then the tongue 53 is inserted between the first plate member 71 and the second plate member 72; next, the pressing piece 4 is installed above the tongue 53 and between the first plate member 71 and the second plate member 72, that is, the pressing piece 4 presses the tongue 53; finally, the pressing piece 4 is screwed to the side wall 31 of the chassis 3, thereby realizing the fixed connection between the PCIe card 5 and the chassis 3.

[0086] Next, the fixation between the adapter board assembly 6 and the chassis 3 will be introduced.

[0087] Please refer to again Figure 3 , the adapter board assembly 6 includes a first screw 61 penetrating along its height direction, wherein the first screw 61 can be a hand-tightening screw, that is, without relying on power tools, only by simple manual tools (such as a screwdriver), the screwing of the first screw 61 can be realized.

[0088] After the adapter board assembly 6 is snap-fitted to the upper surface of the first plate member 71 of the U-shaped member 7, by locking the first screw 61 to the first plate member 71, the fixed connection between the adapter board assembly 6 and the U-shaped member 7 can be realized.

[0089] Since the U-shaped member 7 is fixedly connected to the side wall 31 of the chassis 3, therefore, the fixed connection between the adapter board assembly 6 and the chassis 3 is also realized.

[0090] In this embodiment, after the adapter board assembly 6 is snap-fitted to the upper surface of the first plate member 71 of the U-shaped member 7 and locked to the U-shaped member 7 through the first screw 61; therefore, when the adapter board assembly 6 needs to be disassembled, only the first screw 61 needs to be unlocked, and then the adapter board assembly 6 can be taken out for maintenance. Compared with the prior art where two screws need to be unlocked to disassemble the adapter board assembly 6, in this embodiment, only one first screw 61 needs to be unlocked to disassemble the adapter board assembly 6, which simplifies the process of disassembling the adapter board assembly 6, thereby reducing the workload of the staff for disassembly and maintenance and improving work efficiency.

[0091] In addition, in this embodiment, the PCIe card 5 is fixed to the chassis 3 through the pressing plate 4 and the U-shaped part 7; and the adapter board assembly 6 is fixed to the U-shaped part 7; thus, when the adapter board assembly 6 needs to be disassembled, although the PCIe card 5 is inserted into the groove of the adapter board assembly 6, the force for fixing the PCIe card 5 to the chassis 3 is greater than the frictional force between the PCIe card 5 and the groove of the adapter board assembly 6; therefore, during the process of pulling out the adapter board assembly 6, the PCIe card 5 will not be taken out by the adapter board assembly 6 but will continue to be fixed inside the chassis; furthermore, the separate removal of the adapter board assembly 6 is realized, and the staff does not need to remove the PCIe card 5 again after removing the adapter board assembly 6, thus simplifying the maintenance work of the adapter board assembly 6.

[0092] Moreover, in this embodiment, the first connecting plate 21 of the adapter board assembly 6 is cancelled, so the volume of the adapter board assembly 6 is smaller, saving the internal space of the chassis 3; and when multiple PCIe cards 5 are installed in the chassis 3, interference is not likely to occur between adjacent adapter board assemblies 6, the adapter board assembly 6 is easy to install and maintain, and the adapter board assembly 6 has a long service life and a high reuse rate.

[0093] Figure 4 An exploded structure schematic diagram of a component structure applied to a PCIe card provided by this application Figure 2 , as Figure 4 shown, the component structure includes:

[0094] A pressing plate 4 and at least one connecting component, and the connecting component includes a PCIe card 5, an adapter board assembly 6 and a U-shaped part 7.

[0095] Among them, the closed end of the U-shaped part 7 is fixedly connected to the side wall 31 of the chassis 3; the PCIe card 5 is inserted into the side wall 31 of the chassis 3, and the tongue 53 of the PCIe card 5 is inserted into the open end of the U-shaped part 7; the pressing plate 4 presses the tongue 53 of the PCIe card 5, and the pressing plate 4 is screwed to the side wall 31 of the chassis 3.

[0096] The adapter board assembly 6 is snap-connected to the U-shaped part 7, and the adapter board assembly 6 and the U-shaped part 7 are fixedly connected through a first screw 61.

[0097] In one example, the second plate member 72 of the U-shaped part 7 is attached to the side wall 31 of the chassis 3, and a positioning pin 74 is provided on the first plate member 71 of the U-shaped part 7.

[0098] The adapter board assembly 6 is provided with a positioning hole 62; the U-shaped part 7 is snap-connected to the positioning hole 62 through the positioning pin 74.

[0099] In one example, a first screw hole 75 is provided on the first plate member 71 of the U-shaped member 7; a second screw hole is provided on the adapter plate assembly 6; a first screw 61 passes through the second screw hole and the first screw hole 75 to fixedly connect the adapter plate assembly 6 and the U-shaped member 7.

[0100] In one example, the sum of the thickness of the tongue 53 of the PCIe card 5 and the thickness of the pressing piece 4 is less than or equal to the width of the open end of the U-shaped member 7.

[0101] In one example, the closed end of the U-shaped member 7 is snap-connected to the side wall 31 of the chassis 3; alternatively, the closed end of the U-shaped member is screwed to the side wall 31 of the chassis 3 through a second screw 41.

[0102] In one example, a T-shaped hole 63 is provided on the adapter plate assembly 6; a T-shaped screw 35 is fixedly provided on the upper cover 34 of the chassis 3.

[0103] The T-shaped screw 35 passes through the T-shaped hole 63 to connect the upper cover 34 of the chassis 3 and the adapter plate assembly 6.

[0104] In one example, a connection groove 33 is provided on the side wall 31 of the chassis 3, and the PCIe card 5 is inserted into the connection groove 33.

[0105] In one example, the length of the pressing piece 4 is less than or equal to a first preset value, and the first preset value is the sum of the width of the connection groove 33 and a preset interval distance, and the preset interval distance is the distance width between adjacent connection grooves 33 on the side wall 31 of the chassis 3.

[0106] In one example, the length of the pressing piece 4 is equal to the width of the side wall 31 of the chassis 3.

[0107] Exemplarily, in the fixing manner of the PCIe card 5, the adapter plate assembly 6 and the chassis 3, the content repeated with that in the first embodiment will not be elaborated here, and the following introduces the improvement of the fixing manner.

[0108] On the side wall 31 of the chassis 3, several connection grooves 33 are provided at intervals, wherein the width of the connection groove 33 is adapted to the thickness of the PCIe card 5. During the installation process, the PCIe card body 51 is aligned with the connection groove 33, and after confirming the installation direction of the PCIe card 5 (for example, the installation direction is that the gold fingers 52 face upward), the PCIe card body 51 is slid into the connection groove 33 to achieve the preliminary assembly and fixation between the PCIe card 5 and the chassis 3.

[0109] After the tongue 53 of the PCIe card 5 is inserted into the open end of the U-shaped member 7, the pressing piece 4 also needs to be installed above the tongue 53; therefore, in order to ensure that the tongue 53 and the pressing piece 4 can be smoothly inserted into the open end of the U-shaped member 7, it is necessary to ensure that the width of the open end of the U-shaped member 7 is at least equal to the sum of the thicknesses of the tongue 53 and the pressing piece 4.

[0110] Furthermore, in order to avoid deformation of the locking tongue 53 and the pressing piece 4 during long-term use, an appropriate gap should be reserved for the installation of the locking tongue 53 and the pressing piece 4. That is, the width of the open end of the U-shaped part 7 is greater than the sum of the thicknesses of the locking tongue 53 and the pressing piece 4, so as to reserve a space for stress release during the installation of the locking tongue 53 and the pressing piece 4 and ensure the stability of the overall structure.

[0111] The clamping connection between the adapter plate assembly 6 and the U-shaped part 7 can be achieved through the following structure: The second plate member 72 of the U-shaped part 7 is fixedly connected to the side wall 31 of the chassis 3; a positioning pin 74 (Positioning Pin) is provided on the upper surface of the first plate member 71 of the U-shaped part 7, and a positioning hole 62 adapted to the positioning pin 74 is provided on the adapter plate assembly 6. During installation, align the positioning hole 62 of the adapter plate assembly 6 with the positioning pin 74 of the U-shaped part 7, and push the adapter plate assembly 6 in the direction of the U-shaped part 7. With appropriate force, the clamping connection between the adapter plate assembly 6 and the U-shaped part 7 can be achieved, that is, the initial positioning and fixation between the adapter plate assembly 6 and the U-shaped part 7 can be realized.

[0112] In the first plate member 71 of the U-shaped part 7, a first screw hole 75 is also provided; a second screw hole (not shown in the figure) is provided at the corresponding position of the adapter plate assembly 6, and a first screw 61 is passed through the second screw hole. After the clamping connection between the adapter plate assembly 6 and the U-shaped part 7 is achieved, pass the first screw 61 through the second screw hole of the adapter plate assembly 6 and the first screw hole 75 of the U-shaped part 7 in sequence, and then lock the first screw 61 to realize the fixed connection between the adapter plate assembly 6 and the U-shaped part 7.

[0113] Furthermore, the fixed connection between the U-shaped part 7 and the side wall 31 of the chassis 3 can be that the closed end of the U-shaped part 7 is clamped to the side wall 31 of the chassis 3.

[0114] Among them, the way of clamping the closed end of the U-shaped part 7 to the side wall 31 of the chassis 3 can be that a protrusion (for example, a buckle) is provided at the closed end of the U-shaped part 7, and a notch is provided at the corresponding position of the side wall 31 of the chassis 3. The protrusion provided at the closed end of the U-shaped part 7 cooperates with the notch of the side wall 31 of the chassis 3. When the closed end of the U-shaped part 7 approaches the side wall 31 of the chassis 3, the protrusion at the closed end of the U-shaped part 7 can undergo elastic deformation and be inserted into the notch of the side wall 31 of the chassis 3, thereby realizing the clamping connection between the closed end of the U-shaped part 7 and the side wall 31 of the chassis 3.

[0115] Furthermore, the fixed connection between the U-shaped part 7 and the side wall 31 of the chassis 3 can also be that the closed end of the U-shaped part is screwed to the side wall 31 of the chassis 3 through a second screw 41.

[0116] The closed end of the U-shaped part can be screwed to the side wall 31 of the chassis 3 by means of the second screw 41 provided in the pressing piece 4. For example, after the tongue 53 of the PCIe card 5 and the pressing piece 4 are installed at the open end of the U-shaped part 7, by tightening the second screw 41 in the pressing piece 4 with the side wall 31 of the chassis 3, the screwed connection between the closed end of the U-shaped part and the side wall 31 of the chassis 3 can be achieved.

[0117] Furthermore, the length of the pressing piece 4 can be the sum of the width of the connecting groove 33 and the spacing distance between adjacent connecting grooves 33. Under such conditions, one pressing piece 4 corresponds to the fixation of one PCIe card 5; that is, after the tongue 53 of the PCIe card 5 and the pressing piece 4 are installed at the open end of the U-shaped part 7, the second screw 41 in the pressing piece 4 is tightened with the side wall 31 of the chassis 3 to achieve the fixation between the PCIe card 5 and the chassis 3.

[0118] Furthermore, the length of the pressing piece 4 can also be equal to the width of the side wall 31 of the chassis 3. Under such conditions, one pressing piece 4 corresponds to the fixed connection between all the installed PCIe cards 5 in one chassis 3 and the chassis 3; that is, after the tongues 53 of the respective PCIe cards 5 are installed at the open end of the U-shaped part 7, the pressing piece 4 is also installed at the open end of the U-shaped part 7, and the second screw 41 in the pressing piece 4 is tightened with the side wall 31 of the chassis 3, thereby achieving the fixed connection between the respective PCIe cards 5 and the chassis 3.

[0119] Furthermore, in this embodiment, a connection method between the adapter board assembly 6 and the upper cover 34 of the chassis 3 is also provided. Taking Figure 4 the shown perspective as an example, a T-shaped hole 63 is provided at the right end (the end far from the tongue 53) of the adapter board assembly 6. When observing in the direction from the end close to the tongue 53 to the end far from the tongue 53, the width of the T-shaped hole 63 gradually decreases; on the lower surface of the upper cover 34 of the chassis 3, a T-shaped screw 35 is provided, and the T-shaped screw 35 is fixedly connected to the upper cover 34; wherein, the width of the end of the T-shaped hole 63 on the side far from the tongue 53 is equal to the width of the T-shaped screw 35.

[0120] In this way, during the process of closing the upper cover 34 of the chassis 3, that is, during the process of the upper cover 34 of the chassis 3 sliding from the end close to the tongue 53 to the end far from the tongue 53, due to the gradually decreasing width of the T-shaped hole 63, the T-shaped screw 35 of the upper cover 34 will be gradually locked in the T-shaped hole 63, thereby achieving the fixation between the adapter board assembly 6 and the chassis 3, and further enhancing the connection stability between the connection assembly and the chassis 3.

[0121] When it is necessary to remove the adapter board assembly 6 for maintenance, first, the upper cover 34 of the chassis 3 can be slid from the end away from the tongue 53 to the end close to the tongue 53. Since in this direction, the width of the T-shaped hole 63 gradually increases, the T-shaped screw 35 of the upper cover 34 will be unlocked from the T-shaped hole 63 of the adapter board assembly 6. Next, the worker unscrews the first screw 61, and then the unlocking between the adapter board assembly 6 and the U-shaped part 7 can be realized, and further the unlocking between the adapter board assembly 6 and the chassis 3 can be realized, so as to remove the adapter board assembly 6 to carry out subsequent maintenance work.

[0122] In this embodiment, the PCIe card 5 is fixedly connected to the side wall 31 of the chassis 3 through the U-shaped part 7 and the pressing piece 4; a positioning pin 74 is arranged on the first plate 71 of the U-shaped part 7, and a positioning hole 62 adapted to the positioning pin 74 is arranged in the adapter board assembly 6. Through the cooperation between the positioning pin 74 and the positioning hole 62, the preliminary positioning and clamping between the adapter board assembly 6 and the U-shaped part 7 are realized; and, a first screw hole 75 is arranged on the first plate 71 of the U-shaped part 7, and a first screw 61 is arranged in the adapter board assembly 6. The first screw 61 is passed through the first screw hole 75 to realize the screwing connection between the adapter board assembly 6 and the U-shaped part 7, and finally the fixed connection between the adapter board assembly 6 and the U-shaped part 7 is realized. That is, by respectively fixing the PCIe card 5 and the adapter board assembly 6, when the worker disassembles the adapter board assembly 6, the PCIe card 5 will not be taken out together. The worker does not need to remove the PCIe card 5 again after removing the adapter board assembly 6, thus simplifying the maintenance work of the adapter board assembly 6.

[0123] In addition, in this embodiment, a T-shaped hole 63 with a width gradually decreasing in the locking direction is arranged in the adapter board assembly 6, and a T-shaped screw 35 is fixedly arranged on the lower surface of the upper cover 34 of the chassis 3; when it is necessary to lock the upper cover 34 of the chassis 3 and the adapter board assembly 6, the upper cover 34 is slid in the direction of the decreasing width of the T-shaped hole 63; when it is necessary to unlock the upper cover 34 of the chassis 3 and the adapter board assembly 6, the upper cover 34 is slid in the direction of the increasing width of the T-shaped hole 63. Compared with the need to unlock two screws when disassembling the adapter board assembly 6, in this embodiment, only the upper cover 34 of the chassis 3 needs to be slid (the sliding and unlocking of the upper cover 34 can be completely dependent on manual work without the aid of external tools), and the first screw 61 is unlocked, then the adapter board assembly 6 can be removed, thus simplifying the maintenance work of the adapter board assembly 6.

[0124] Figure 5 It is a schematic structural diagram of the chassis provided by the present application, as Figure 5 shown, the components and structures provided in the above embodiments are arranged in the chassis 3.

[0125] In one example, a bottom support 8 for supporting the PCIe card 5 is arranged on the lower side of the chassis 3.

[0126] Exemplarily, a bottom support member 8 is provided between the lower side of the chassis 3, that is, on the bottom plate 32 of the chassis 3, and the bottom of the PCIe card 5; wherein, the bottom support member 8 can be fixedly connected to the bottom plate 32 of the chassis 3 by screws.

[0127] The bottom support member 8 is used to support the PCIe card 5 to reduce the force on the tongue 53 of the PCIe card 5, thereby optimizing the force condition of the PCIe card 5, reducing the deformation of the PCIe card 5 caused by uneven force, and extending the service life of the PCIe card 5.

[0128] In this embodiment, by providing the bottom support member 8 between the bottom plate 32 of the chassis 3 and the bottom of the PCIe card 5, the force condition of the PCIe card 5 is improved, and the service life of the PCIe card 5 is extended.
