Description

Technical Field

[0001] This application relates to the field of fixed structure technology, and in particular to a fixed structure. Background Technology

[0002] Ensuring the stable fixation of components in electronic assemblies has always been a pressing problem in the field. For example, when a user wants to more securely mount a processing module (e.g., a graphics processing unit (GPU)) in a frame, additional fixing structures are typically used to secure the module and enhance the fixation effect. Specifically, the processing module has extensions (e.g., GPU metal parts) disposed around it. When the user mounts the processing module in the frame, the extensions can move along grooves or tracks provided on the inner wall of the frame, facilitating installation. Therefore, the additional fixing structure can be used to abut against the extensions, thereby achieving the purpose of securing the processing module.

[0003] However, the specifications of processing modules manufactured by different brands are not entirely the same. For example, the length of the extension parts of different specifications of processing modules varies, and existing fixing structures can only fix processing modules with specific specifications. Therefore, when users select processing modules of other specifications, fixing structures that can accommodate different specifications of processing modules must be manufactured, which increases product development costs. Therefore, enabling the fixing structure to cope with the dimensional differences between various specifications of processing modules, or the tolerance issues between processing modules of the same specification, is one of the key design considerations for the fixing structure.

[0004] In addition, due to the narrow space inside the chassis, whether the mounting structure is easy to operate and can securely hold the processing module in place so that the processing module does not jump out of the chip is also one of the key design considerations for the mounting structure.

[0005] Therefore, how to propose a fixed structure that can solve the above problems is one of the issues that the industry is currently eager to invest research and development resources to address. Summary of the Invention

[0006] Therefore, it is necessary to provide a fixing structure to address the problem that traditional fixing structures are difficult to adapt to processing modules of different sizes and the dimensional differences of processing modules due to tolerances.

[0007] According to a first aspect of this application, a fixing structure is proposed, comprising:

[0008] The fixing part is configured to be fixed to a frame;

[0009] The movable part is slidably connected to the fixed part, and the movable part is configured to abut against a processing module in the frame;

[0010] At least one first elastic member, wherein the two ends of the at least one first elastic member respectively abut against the fixed part and the movable part;

[0011] A button, slidably connected to the fixed portion, the button being configured to selectively engage or disengage with the movable portion; and

[0012] The second elastic element, wherein both ends of the second elastic element abut against the fixing part and the button respectively;

[0013] The button is configured to slide along the first direction and disengage from the movable part when subjected to a pressing force along the first direction, so that the second elastic element is compressed along the first direction.

[0014] The first elastic member is configured to push the movable part away from the fixed part in a second direction when the button is disengaged from the movable part, and abut against an extension of the processing module located in the frame, the extension being disposed on the periphery of the processing module.

[0015] In one embodiment, two first elastic elements are provided, and the two first elastic elements are located on opposite sides of the button.

[0016] In one embodiment, the two first elastic elements are arranged along a third direction with the button;

[0017] The first direction, the second direction, and the third direction are perpendicular to each other.

[0018] In one embodiment, the movable part includes a first engaging part, and the button includes a second engaging part, the first engaging part and the second engaging part engaging with each other so that the movable part is fixed relative to the fixed part.

[0019] In one embodiment, the first engagement portion includes a plurality of first serrations and a plurality of first grooves defined by the plurality of first serrations; the second engagement portion includes a plurality of second serrations and a plurality of second grooves defined by the plurality of second serrations; the plurality of first serrations are configured to engage with the plurality of second grooves, and the plurality of second serrations are configured to engage with the plurality of first grooves.

[0020] In one embodiment, the plurality of first saw teeth includes a first vertical surface and a first inclined surface, and the plurality of second saw teeth includes a second vertical surface and a second inclined surface.

[0021] In one embodiment, when the button is pressed in the first direction, the second engaging portion is able to slide relative to the first engaging portion in the first direction.

[0022] In one embodiment, the fixed part includes two sliding grooves disposed opposite to each other along the first direction, and the movable part includes two protrusions corresponding to the two sliding grooves, the two protrusions being configured to slide in the two sliding grooves along the second direction respectively.

[0023] In one embodiment, the fixing structure further includes a pivot portion pivotally connected to and rotatable relative to a top cover, the top cover being connected to the frame and located above the processing module.

[0024] In one embodiment, a receiving space is formed between the fixed part and the movable part, the button is located within the receiving space, and the button is configured to selectively protrude or retract relative to the receiving space.

[0025] In the technical solution of this application, the button and the fixing member are slidably connected in the fixing structure, and the force direction of the button is the same as the compression direction of the second elastic member, thus making the fixing structure easier to operate. Furthermore, the fixing structure of this application can have two first elastic members, with the button located between the two first elastic members, which can make the force on the moving part more even and achieve a more stable fixing effect.

[0078] In addition, the illustrations provided in this application are drawn to scale. To maintain the brevity of the specification, the proportions of each component are not listed in detail, but the proportions and positions of each component should be considered part of the content of this specification.

[0079] Please refer to Figure 1 . Figure 1 This is a perspective view of an electronic component 10 according to one embodiment of this application. In this embodiment, as... Figure 1 As shown, the electronic component 10 includes a fixing structure 100, multiple processing modules 200, a frame 300, and a top cover 400. The processing modules 200 are configured to be mounted on the frame 300. The electronic component 10 may include positioning posts 302. The fixing structure 100 is fixed to the frame 300 via the positioning posts 302 and is configured to secure the processing modules 200 located within the frame 300, so that the processing modules 200 can be stably fixed within the frame 300. The top cover 400 is located above the processing modules 200. The top cover 400 is configured to cover and protect the processing modules 200. The fixing structure 100 includes a pivot portion 102. The fixing structure 100 is rotatably pivoted to the top cover 400 via the pivot portion 102. When not fixed by the positioning posts 302, the fixing structure 100 can pivot relative to the top cover 400 in the direction of arrow A1.

[0080] Please refer to Figure 2 . Figure 2 This is a perspective view of an electronic component 10 according to one embodiment of this application. In this embodiment, a processing module 200 is mounted on a frame 300. The processing module 200 includes a housing 205 and an extension 210 disposed around the periphery of the housing 205. A fixing structure 100 is configured to abut against the extension 210 of the processing module 200 to prevent the processing module 200 from detaching from the frame 300.

[0081] In some implementations, the processing module 200 may be a graphics processing unit (GPU) or any suitable component. This application does not limit the type or shape of the processing module 200.

[0082] In some implementations, frame 300 may be a riser cage.

[0083] The following will describe in detail the structure, function, and connection relationship between each component included in the fixing structure 100 of this embodiment.

[0084] Please also refer to Figure 3 and Figure 4 . Figure 3 This is a perspective view of the fixing structure 100 according to one embodiment of this application. Figure 4 This is an exploded view of a fixing structure 100 according to an embodiment of this application. In this embodiment, the fixing structure 100 includes a fixing part 110, a movable part 120, a button 130, a first elastic member 140, and a second elastic member 150. To clearly illustrate the position of each component, [the following is a partial view of the structure]. Figure 3The movable part 120 is transparent and outlined with dashed lines. The fixed part 110 is slidably connected to the movable part 120 along the x-direction. More specifically, the fixed part 110 has two opposing sliding grooves 114. The movable part 120 has a plurality of protrusions 124 corresponding to the sliding grooves 114. The two sliding grooves 114 are slidably connected to the two protrusions 124 along the x-direction. In other words, the protrusions 124 are configured to slide relative to the sliding grooves 114 along the x-direction. The fixed part 110 has a through hole 116. The button 130 passes through the through hole 116 and is slidably connected to the fixed part 110 in the y-direction. The button 130 is configured to selectively engage or disengage from the movable part 120 by pressing. A first elastic member 140 is disposed between the fixed part 110 and the movable part 120. The two ends of the first elastic member 140 abut against the fixed part 110 and the movable part 120, respectively. A second elastic member 150 is disposed between the button 130 and the fixed part 110. The two ends of the second elastic member 150 abut against the fixed part 110 and the button 130, respectively.

[0085] In some embodiments, the first elastic element 140 and the second elastic element 150 may be springs or other suitable elastic materials.

[0086] Please also refer to Figure 1 as well as Figure 3 In some embodiments, the fixing part 110 has a positioning hole 112. The positioning hole 112 is used to correspond to the positioning post 302. The positioning post 302 passes through the positioning hole 112 to fix the fixing part 110 to the frame 300.

[0087] Please refer to Figure 5 . Figure 5 This is a perspective view of the fixing structure 100 according to an embodiment of this application. For clarity, Figure 5 The fixed portion 110 is transparent and its outline is shown as a dashed line. In this embodiment, the movable portion 120 has two receiving grooves 122 for accommodating two first elastic members 140. The two receiving grooves 122 are located on opposite sides of the button 130 along the y-direction; in other words, the two first elastic members 140 are located on opposite sides of the button 130. The button 130 is located between the two first elastic members 140 in the y-direction. This structural design allows the movable portion 120 to experience more even force when the first elastic members 140 return to their original position and push against the movable portion 120 using their own elastic force.

[0088] Please continue to refer to this. Figure 5 In this embodiment, the fixed portion 110 and the movable portion 120 form a receiving space OP. A button 130 and a second elastic member 150 are disposed in the receiving space OP. The button 130 extends outward from the receiving space OP. The button 130 is configured to selectively protrude partially from the through-hole 116 or retract into the receiving space OP by applying pressure and the second elastic member 150.

[0089] Please continue to refer to this. Figure 5 In this embodiment, the movable part 120 includes a first engaging part 126 and a contact surface 128. The contact surface 128 is located on the side of the movable part 120 away from the fixed part 110. The contact surface 128 abuts against the processing module 200. The button 130 includes a second engaging part 136. The first engaging part 126 and the second engaging part 136 engage with each other in the x-direction, so that the movable part 120 and the button 130 are engaged, thereby preventing relative sliding in the x-direction. In some embodiments, the second engaging part 136 is on the receiving groove 122.

[0090] Please also refer to Figure 4 and Figure 5 In some embodiments, protrusions 124 are provided on the outer side wall of the receiving groove 122. Protrusions 124 may be provided on the two outer side walls of the two receiving grooves 122 respectively. In some embodiments, the movable part 120 is slidably connected to the sliding groove 114 of the fixed part 110 through the protrusions 124 on the receiving groove 122.

[0091] The operation of the fixed structure 100 will be described in detail below.

[0092] Please also refer to Figure 5 as well as Figure 6 . Figure 6 This is a perspective view of the fixing structure 100 according to one embodiment of this application. In this embodiment, the button 130 is configured to receive a pressing force F1 from the direction y. The pressing force F1 causes the button 130 to slide along the direction y (see...). Figure 6 When button 130 slides in direction y, the second engaging portion 136 slides relative to the first engaging portion 126 in direction y, causing the first engaging portion 126 to separate from the second engaging portion 136. When button 130 slides in direction y, the second elastic member 150 is compressed in direction y. When the first engaging portion 126 of movable portion 120 separates from the second engaging portion 136 of button 130, the first elastic member 140 returns to its original position by its own elastic force, pushing against movable portion 120, causing movable portion 120 to slide away from fixed portion 110 in direction x.

[0093] Please refer to Figure 6 and Figure 7 . Figure 7 This is a perspective view of the fixing structure 100 according to one embodiment of this application. In some embodiments, when the button 130 stops being pressed by the pressure F1 along the y direction, the second elastic member 150 can push the button 130 back by its own elastic force, so that the button 130 returns to its original position in the opposite direction of the y direction.

[0094] Please refer to Figure 5 and Figure 7 . Figure 5 The embodiments compared to Figure 7 In this embodiment, the first engaging portion 126 and the second engaging portion 136 have different engaging positions in the x-direction. More precisely, after the button 130 is pressed, the button 130 disengages from the movable portion 120, causing the first engaging portion 126 to move away from the fixed portion 110 and the button 130 in the x-direction. Therefore, when the button 130 returns to its original position in the y-direction via the second elastic member 150, the second engaging portion 136 engages with the portion of the first engaging portion 126 that is further away from the abutment surface 128.

[0095] With the aforementioned structural configuration, in a usage scenario, when button 130 is pressed by force F1 and moves relative to fixed part 110, the second engaging part 136 of button 130 disengages from the first engaging part 126 of movable part 120, causing the first elastic element 140 to elastically recover, and causing movable part 120 to move in a direction x away from fixed part 110 and abut against processing module 200, thereby achieving the purpose of fixing processing module 200. Then, when button 130 is no longer pressed by force F1 and the second elastic element 150 returns to its elastic force (e.g., ... Figure 7 As shown, this can prevent the movable part 120 from moving again, thereby achieving the purpose of stably fixing the electronic components.

[0096] In some embodiments, the direction of the pressing force (e.g., direction y) is perpendicular to the direction in which the movable part 120 slides away from the fixed part 110 (e.g., direction x). In some embodiments, the button 130 and the first elastic member 140 are arranged along direction z (e.g., the button 130 is located between the two first elastic members 140 in direction z). Directions x, y, and z are perpendicular to each other. In some embodiments, the direction of the elastic return of the first elastic member 140 (e.g., direction y) is perpendicular to the direction of the elastic return of the second elastic member 150 (e.g., direction x). In some embodiments, the direction of the reciprocating slide of the button 130 (e.g., direction y) is parallel to the direction in which the second elastic member 150 is compressed by the pressing force. Since the direction of the sliding of the button 130 is the same as the direction of the elastic compression of the second elastic member 150, pressing the button 130 can be more effortless and easier.

[0097] The following will describe in detail the method by which the fixed structure 100 fixes the processing module 200 of this application.

[0098] Please refer to Figure 8 . Figure 8 This is a top view of the fixing structure 100 and the processing module 200 according to one embodiment of this application. For simplicity, in Figure 8The frame 300 and top cover 400 are omitted. In this embodiment, the processing module 200 includes a housing 205 and an extension 210. The movable part 120 of the fixing structure 100 is directly opposite the extension 210 in the x-direction. There is a distance D1 between the movable part 120 and the extension 210 in the x-direction. The distance D1 may vary depending on the specifications or dimensions of the processing module 200.

[0099] In some embodiments, due to the large size of the processing module 200 (e.g., the extension 210 is long), the distance D1 may be 0 before the button 130 is pressed. In other words, the extension 210 may abut against the abutment surface 128 of the movable part 120 before the fixed structure 100 is actuated.

[0100] Please refer to Figure 9 . Figure 9 for Figure 8 The fixed structure 100 and the processing module 200 are viewed in cross section 9-9. In this embodiment, the second elastic member 150 is disposed in the receiving groove 132 of the button 130. The movable part 120 and the extension member 210 have a distance D1 in the x-direction. The first engaging part 126 includes a plurality of first serrations 1261. The first engaging part 126 includes a plurality of first grooves 1262 defined by the first serrations 1261. The second engaging part 136 of the button 130 further includes a plurality of second serrations 1361, and the second engaging part 136 includes a plurality of second grooves 1362 defined by the second serrations 1361. The first serrations 1261 are configured to engage with the second grooves 1362. The second serrations 1361 are configured to engage with the first grooves 1262. The first serrations 1261 include a first vertical surface 1261a and a first inclined surface 1261b. The second sawtooth 1361 includes a second vertical surface 1361a and a second inclined surface 1361b.

[0101] In some alternative embodiments, the first saw tooth 1261 may include two parallel extending vertical surfaces and a plane connecting the two vertical surfaces. The second saw tooth 1361 may also include two parallel extending vertical surfaces and a plane connecting the two vertical surfaces. Accordingly, the first saw tooth 1261 and the second saw tooth 1361 can engage more stably.

[0102] In some implementations, such as Figure 9 As shown, the first vertical surface 1261a is located on the side of the first sawtooth 1261 closest to the fixed portion 110 and faces the fixed portion 110. The first inclined surface 1261b is located on the side of the first sawtooth 1261 furthest from the fixed portion 110 and faces the movable portion 120. The second vertical surface 1361a is located on the side of the second sawtooth 1361 furthest from the fixed portion 110 and faces the movable portion 120. The second inclined surface 1361b is located on the side of the second sawtooth 1361 closest to the fixed portion 110 and faces the fixed portion 110.

[0103] In some implementation methods, please refer to Figure 6 and Figure 9 During the period when button 130 is pressed and slides in direction y, the second engagement portion 136 slides in direction y relative to the first engagement portion 126. In other words, when button 130 is pressed, the second serration 1361 slides in direction y relative to the first groove 1262.

[0104] Please also refer to Figure 8 , Figure 10 and Figure 11 . Figure 10 This is a top view of the fixing structure 100 fixing processing module 200 according to an embodiment of this application. Figure 11 for Figure 10 The fixed structure 100 and the processing module 200 are viewed in cross section 11-11. In this embodiment, by pressing button 130, the movable part 120 moves in the x-direction and abuts against the extension 210. More specifically, button 130 is configured to separate from movable part 120 under pressure in the y-direction. After the first engagement part 126 separates from the second engagement part 136, the movable part 120 moves in the x-direction so that the abutting surface 128 abuts against the extension 210 (e.g., ...). Figure 10 , Figure 11 As shown), this achieves the effect of fixing the processing module 200. In other words, after the moving part 120 moves along the x-direction, Figure 8 The distance D1 shown is actually 0.

[0105] Please also refer to Figure 9 and Figure 11 In this embodiment, by pressing the button 130, the first engagement portion 126 moves along the direction x by the distance of two first serrations 1261 and one first groove 1262.

[0106] In some embodiments, the movable part 120 can move approximately 4.5 mm relative to the fixed part 110. The distance the movable part 120 can move relative to the fixed part 110 is determined by the elastic coefficient of the first elastic member 140 and / or the length of the sliding groove 114. It should be noted that the distance the movable part 120 can slide relative to the fixed part 110 can be adjusted according to the dimensions of different processing modules 200 that may require fixing, and this application is not limited thereto.

[0107] In one embodiment of this application, the fixed structure of this application can be set in a server. The server can be used for artificial intelligence (AI) computing, edge computing, or as a 5G server, cloud server, or vehicle networking server.

[0108] In summary, because the button of this application moves in the same direction as the second elastic member under pressure, the button can easily slide relative to the fixing member. Furthermore, since this application has multiple first elastic members located on opposite sides of the button, it can provide a more even resistance force, allowing the moving part to stably abut against the extension without jumping. Moreover, because the fixing structure of this application includes a moving part, it can effectively solve the tolerance problem between different specifications of processing modules, enabling the fixing structure to be compatible with various brands and significantly reducing development costs.

[0109] The foregoing description is only for illustrating and describing exemplary embodiments of this application and is not intended to exhaustively describe or limit the precise form of the invention disclosed in this application. The above teachings may be modified or varied.

[0110] The selected and illustrated embodiments are intended to explain the content of this application and their practical application, thereby inspiring other skilled in the art to utilize this application and various embodiments, and to make various modifications to suit a particular intended use. Alternative embodiments will be apparent to those skilled in the art without departing from the spirit and scope of this application. Therefore, the scope of this application is defined by the appended claims, and not by the foregoing description and the exemplary embodiments described therein.
