[0088] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0089] like Figures 1 to 3 As shown, this embodiment provides a chassis 200 including a body 201 , a motherboard 202 , a graphics card 203 , and a graphics card fixing structure 100 .

[0090] For the convenience of subsequent reading, the present application introduces a first direction X, a second direction Y, and a third direction Z to describe the embodiments of the present application. The first direction X, the second direction Y, and the third direction Z may be three non-parallel linear directions in space; further, the first direction X, the second direction Y, and the third direction Z may be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In the subsequent embodiments, the first direction X is the X-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction Y is the Y-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction Z is the Z-axis direction of the coordinate axis of the three-dimensional coordinate system.

[0091] The chassis 200 is applied to a desktop computer. It is understandable that the chassis 200 can also be applied to other computers equipped with a graphics card 203, such as an all-in-one computer or a notebook computer.

[0092] The body 201 has a cavity inside, and the motherboard 202 is installed in the cavity of the body 201 and fixed to the body 201. The graphics card 203 is installed on the motherboard 202 and is electrically connected to the motherboard 202 to form a signal transmission channel.

[0093] A fixing plate 204 is protruding from the motherboard 202. Along the first direction X, one end of the graphics card 203 is abutted against the fixing plate 204 and can be fixed to the fixing plate 204 by means of screws or bolts. A connecting plate 205 is provided at the other end of the graphics card 203. The connecting plate 205 is installed on the motherboard 202 through the graphics card fixing structure 100, thereby fixing the graphics card 203 on the motherboard 202.

[0094] like Figures 2 to 4 As shown, this embodiment further provides a graphics card fixing structure 100 , including a fixing base 10 , a first connecting member 20 , a fixing bracket 30 , and a second connecting member 40 .

[0095] Along the third direction Z, the fixed base 10 is located above the motherboard 202. Along the first direction X, the fixed base 10 is arranged at intervals on one side of the fixing plate 204, so that a space for installing the graphics card 203 is formed between the fixed base 10 and the fixing plate 204. In addition, along the first direction X, the fixed base 10 is slidably connected to the motherboard 202.

[0096] The first connecting member 20 detachably connects the fixing base 10 and the mainboard 202 to limit the fixing base 10 from sliding relative to the mainboard 202 .

[0097] The fixing bracket 30 is connected to a side of the fixing base 10 away from the motherboard 202. Along the first direction X, a side of the fixing bracket 30 close to the graphics card 203 is provided with a plurality of slots 310, and the plurality of slots 310 are used to position the graphics card 203. The connecting pieces 205 of graphics cards 203 of different models are clamped in the corresponding slots 310, so that the graphics card 203 is pressed against the fixing piece 204 through the fixing bracket 30.

[0098] The second connecting member 40 is disposed on the fixing bracket 30 , and is used to detachably connect the fixing bracket 30 and the connecting piece 205 of the graphics card 203 , so as to make the graphics card 203 and the fixing bracket 30 detachable.

[0099] Thus, in the graphics card fixing structure 100 of the present application, the fixing bracket 30 is provided with a plurality of slots 310 for accommodating the connecting pieces 205 of different types of graphics cards 203. In addition, the fixing bracket 30 is provided with a second connecting member 40, which is used to fix the fixing bracket 30 and the connecting piece 205 of the graphics card 203, so as to adaptively select the way of engagement or fastening of the second connecting member 40 according to the connecting piece 205 of different types of graphics cards 203. At the same time, the fixing bracket 30 is installed on the fixing base 10, and the fixing base 10 can slide relative to the motherboard 202 to adjust the position of the fixing base 10 on the motherboard 202, so that the fixing bracket 30 can flexibly support graphics cards 203 of different lengths, so as to further adapt to different types of graphics cards 203.

[0100] Please combine again Figures 4 to 7 In one embodiment, the graphics card fixing structure 100 further includes a first fixing member 50. The first fixing member 50 is located on a side of the motherboard 202 away from the fixing base 10, and one end of the first fixing member 50 passing through the motherboard 202 is detachably connected to the fixing base 10.

[0101] A slide groove 2021 is provided on a side of the mainboard 202 away from the fixed base 10. The slide groove 2021 extends along the first direction X and penetrates the mainboard 202 along the third direction Z. One end of the first fixing member 50 is located on the side of the mainboard 202 away from the fixed base 10. The other end of the first fixing member 50 is detachably connected to the fixed base 10 after passing through the slide groove 2021. The portion of the first fixing member 50 that passes through the slide groove 2021 is slidably received in the slide groove 2021, so that the fixed base 10 slides along the first direction X relative to the mainboard 202 through the first fixing member 50.

[0102] Further, the first fixing member 50 includes a first end portion 51, a first smooth section 52 and a first threaded end 53 which are connected in sequence. The first end portion 51, the first smooth section 52 and the first threaded end 53 are connected in an integral manner.

[0103] The first end portion 51 is generally in a circular pancake-shaped structure and is located at a side of the mainboard 202 away from the fixed base 10. The outer diameter of the first end portion 51 is larger than the width of the slide slot 2021, so that the portion of the first end portion 51 that exceeds the slide slot 2021 can abut against the side of the mainboard 202 away from the fixed base 10.

[0104] One end of the first smooth section 52 is connected to a side of the first end portion 51 close to the main board 202, and the first smooth section 52 is at least partially slidably received in the slide groove 2021. The outer diameter of the first smooth section 52 is substantially the same as the groove width of the slide groove 2021, so that the inner wall of the slide groove 2021 can abut against the outer peripheral surface of the first smooth section 52, so that the first smooth section 52 is guided to slide along the first direction X by the inner wall of the slide groove 2021.

[0105] The first threaded end 53 is connected to one end of the first smooth section 52 passing through the slide groove 2021 . A first threaded hole 11 is defined on one side of the fixed base 10 close to the main board 202 . The first threaded end 53 is threadedly connected to the first threaded hole 11 .

[0106] It is worth noting that the number of the first fixing members 50 can be set to two, three, four, or more than four, etc., and the specific number can be selected according to actual design requirements.

[0107] For example, the number of the first fixing members 50 is four, and the four first fixing members 50 are distributed in a rectangular shape. The number of the slide grooves 2021 is set to two, and along the second direction Y, the two slide grooves 2021 are parallel and spaced apart, the first smooth sections 52 of the two first fixing members 50 can be slidably received in one slide groove 2021, and the first smooth sections 52 of the other two first fixing members 50 can be slidably received in the other slide groove 2021.

[0108] It is understandable that when the number of the first fixing members 50 is four, the number of the slide grooves 2021 can also be set to four, and the four slide grooves 2021 are distributed in a rectangular shape and are arranged corresponding to the four first fixing members 50.

[0109] Please combine again Figures 5 to 7 In one embodiment, the graphics card fixing structure 100 further includes a mounting member 60. The mounting member 60 is located on a side of the motherboard 202 away from the fixing base 10 and is detachably connected to the fixing base 10.

[0110] Furthermore, the graphics card fixing structure 100 further includes a second fixing member 70. The second fixing member 70 is located on a side of the mounting member 60 away from the motherboard 202, and is detachably connected to the fixing base 10. The motherboard 202 is provided with a through slot 2022, the through slot 2022 extending along the first direction X, and a portion of the second fixing member 70 is slidably received in the through slot 2022.

[0111] The second fixing member 70 includes a second end portion 71, a second smooth section 72 and a second threaded end 73 which are connected in sequence. The second end portion 71, the second smooth section 72 and the second threaded end 73 are connected in an integral manner.

[0112] The second end 71 is located at a side of the mainboard 202 away from the fixing base 10 , and the outer diameter of the second end 71 is larger than the width of the through slot 2022 , so that the portion of the second end 71 beyond the through slot 2022 can abut against the side of the mainboard 202 away from the fixing base 10 .

[0113] The mounting member 60 defines a through hole 62 . One end of the second smooth section 72 away from the second end portion 71 passes through the through hole 62 and is slidably received in the through slot 2022 .

[0114] The second threaded end 73 is connected to one end of the second smooth section 72 that passes through the through slot 2022. The fixed base 10 is provided with a second threaded hole 13. The second threaded end 73 is threadedly connected to the second threaded hole 13, so that the mounting member 60 and the fixed base 10 are relatively fixed. The through slot 2022 is set so that when the fixed base 10 slides relative to the main board 202, the mounting member 60 can also slide relative to the main board 202 with the fixed base 10.

[0115] In particular, the mounting member 60 is provided with a limiting protrusion 61, which is located on a side of the mounting member 60 close to the main board 202. A limiting groove 14 is provided on a side of the fixed base 10 close to the main board 202, and one end of the limiting protrusion 61 away from the mounting member 60 passes through the through groove 2022 and is received in the limiting groove 14, so that the mounting member 60 and the fixed base 10 are relatively fixed by the limiting protrusion 61 and the second fixing member 70.

[0116] Please combine again Figures 5 to 7 In one embodiment, one end of the first connecting member 20 is located on a side of the fixed base 10 away from the main board 202, and the other end of the first connecting member 20 passes through the fixed base 10 and the main board 202 and is detachably connected to the mounting member 60. The mounting member 60 is provided with a connecting hole 63, and the bottom end of the first connecting member 20 passes through the through slot 2022 and is connected to the connecting hole 63.

[0117] Specifically, the first connecting member 20 is a spring screw, and includes a shell 21, a connecting portion 22 and an elastic member 23. The shell 21 is a structure with both ends open and a hollow interior, and the connecting portion 22 is inserted through the shell 21, and the connecting portion 22 can slide relative to the shell 21. The top end of the connecting portion 22 passes through the top end of the shell 21 for screwing, and the bottom end of the connecting portion 22 passes through the bottom end of the shell 21 and can be threadedly connected to the connecting hole 63.

[0118] The fixing base 10 is provided with a first fixing hole 15, and the first fixing hole 15 penetrates the fixing base 10 along the third direction Z. The first fixing hole 15 includes a first section 151 and a second section 152, the first section 151 is connected to the second section 152, and the outer diameter of the first section 151 is smaller than the outer diameter of the second section 152, so that a step surface P is formed between the first section 151 and the second section 152. The shell 21 includes a first section 211 and a second section 212 connected in sequence, the first section 211 is clamped in the first section 151, the second section 212 is accommodated in the second section 152, and one end of the second section 212 close to the first section 211 is pressed against the step surface P.

[0119] The elastic member 23 is a spring and is sleeved on the outer circumference of the connecting portion 22. One end of the elastic member 23 abuts against the connecting portion 22, and the other end abuts against the shell 21 to provide elastic force to the connecting portion 22. When the connecting portion 22 is fixed to the connecting hole 63, the connecting portion 22 moves downward relative to the shell 21, and the elastic member 23 is continuously compressed. When the connecting portion 22 is separated from the connecting hole 63, the elastic member 23 resets and abuts against the connecting portion 22 to make it move upward relative to the shell 21 and then reset.

[0120] In this way, when the connecting portion 22 is fixed to the connecting hole 63, the mounting member 60 is pressed against the bottom end of the mainboard 202, and one end of the second section 212 close to the first section 211 is pressed against the step surface P, thereby pressing the fixing base 10 against the mainboard 202, so that the fixing base 10 and the mounting member 60 clamp the mainboard 202 so that the three are relatively fixed.

[0121] Please combine again Figures 5 to 7 In one embodiment, a clamping groove 16 is formed on a side of the fixing base 10 away from the mainboard 202 , and a clamping protrusion 33 is formed on the bottom end of the fixing bracket 30 , and the clamping protrusion 33 is clamped in the clamping groove 16 .

[0122] The fixing base 10 is provided with a second fixing hole 12, and the bottom end of the fixing bracket 30 is provided with a third fixing hole 34. The third fixing hole 34 is provided corresponding to the second fixing hole 12, and the number of the third fixing hole 34 and the second fixing hole 12 are both four and are distributed in a rectangular shape. It is understandable that the number of the third fixing hole 34 and the second fixing hole 12 can also be two or six or other numbers.

[0123] Furthermore, the graphics card fixing structure 100 further includes a third connecting member 80 , and the fixing bracket 30 and the fixing base 10 are detachably connected via the third connecting member 80 .

[0124] The third connecting member 80 is a screw or a bolt, etc., which passes through the second fixing hole 12 from a side of the fixing base 10 away from the fixing bracket 30 and is connected to the third fixing hole 34 , thereby fixing the fixing base 10 and the fixing bracket 30 .

[0125] Please combine again Figures 5 to 8 In one embodiment, a first fixing protrusion 31 is convexly disposed on one side of the fixing bracket 30 close to the graphics card 203. Along the second direction Y, a plurality of slots 310 are spaced apart on one side of the first fixing protrusion 31 close to the graphics card 203, so that when different models of graphics cards 203 are used, the connecting piece 205 of the graphics card 203 can be clamped in the corresponding slots 310.

[0126] The number of the first fixing protrusions 31 may be two or more. Along the third direction Z, two or more first fixing protrusions 31 are arranged at intervals, and each first fixing protrusion 31 is provided with a plurality of slots 310 .

[0127] When the connecting piece 205 is a “U”-shaped structure or an “L”-shaped structure, the connecting piece 205 is connected to the fixing bracket 30 by being clamped in the clamping slot 310 .

[0128] Please combine again Figures 5 to 7 , and see Figure 3 In one embodiment, a second fixing protrusion 32 is provided on one side of the fixing bracket 30 close to the graphics card 203. Along the third direction Z, the second fixing protrusion 32 is located above and / or below the first fixing protrusion 31.

[0130] The second fixing protrusion 32 defines a fourth fixing hole 320 that penetrates the second fixing protrusion 32 along the third direction Z. The second connecting member 40 passes through the fourth fixing hole 320 and is connected to the hole groove defined by the connecting piece 205. The second connecting member 40 is a spring screw.

[0131] When the connecting piece 205 is a “C”-shaped structure, the connecting piece 205 is connected to the fixing bracket 30 by means of threaded fastening of the second connecting member 40 and the threaded hole provided on the connecting piece 205 .
