Description

Technical Field

[0001] The present application relates to the technical field of fixed structures, and in particular to a fixed structure. Background Art

[0002] How to ensure that the components in electronic components are stably fixed has always been a problem that the art urgently needs to solve. For example, when a user wants to install a processing module (e.g., a graphics processing unit (GPU)) more firmly in a frame, in order to enhance the fixing effect, an additional fixing structure can generally be used to stop and fix the processing module. Specifically, the processing module has an extension piece (e.g., a GPU iron piece) disposed around it. When the user installs the processing module in the frame, the extension piece can be moved along a groove or track disposed on the inner wall of the frame, thereby facilitating the installation of the user. Therefore, the extension piece can be abutted against by the additional fixing structure to achieve the purpose of stopping and fixing the processing module.

[0003] However, the specifications of processing modules manufactured by different brands are not the same. For example, the lengths of extensions of processing modules of different specifications are different, and the existing fixed structure can only fix processing modules with specific specifications. Therefore, when the user selects a processing module of other specifications, it is necessary to manufacture a fixed structure that can meet the processing modules of different specifications, which leads to an increase in the cost of product development. Therefore, one of the design focuses of the fixed structure is to enable the fixed structure to cope with the size difference problem between processing modules of various specifications, or to cope with the tolerance problem between processing modules of the same specification.

[0004] In addition, due to the narrow space inside the chassis, whether the fixing structure is easy to operate and whether it can firmly fix the processing module to prevent the processing module from jumping is also one of the design focuses of the fixing structure.

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

[0006] Based on this, it is necessary to provide a fixing structure to address the problem that the traditional fixing structure is difficult to adapt to processing modules of different sizes and the size differences of the processing modules due to tolerance.

[0007] According to a first aspect of the present application, a fixing structure is provided, comprising:

[0008] A fixing portion configured to be fixed on a frame;

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

[0010] At least one first elastic member, wherein two ends of the at least one first elastic member are respectively in contact with the fixed portion and the movable portion;

[0011] a button, slidably connected to the fixed portion, the button being configured to be selectively engageable with or disengageable from the movable portion; and

[0012] A second elastic member, wherein two ends of the second elastic member are respectively in contact with the fixing portion and the button;

[0013] Wherein, the button is configured to slide along the first direction and disengage from the movable portion when subjected to a pressing force along the first direction, so that the second elastic member is compressed along the first direction;

[0014] Wherein, the first elastic member is constructed to push the movable part away from the fixed part along the second direction when the button is disengaged from the movable part, and abut against an extension member of the processing module located in the frame, and the extension member is arranged on the peripheral side of the processing module.

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

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

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

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

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

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

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

[0022] In one embodiment, the fixed portion includes two sliding grooves arranged opposite to each other along the first direction, and the movable portion includes two protrusions corresponding to the two sliding grooves, and the two protrusions are constructed to be able to slide in the two sliding grooves along the second direction respectively.

[0023] In one embodiment, the fixing structure further includes a pivoting portion, the pivoting portion is pivotally connected to a top cover and can rotate relative to the top cover, and the top cover is connected to the frame and is located above the processing module.

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

[0025] In the technical solution of the present application, in the fixing structure of the present application, the button and the fixing member are slidably connected, and the force direction of the button is the same as the compression direction of the second elastic member, so the fixing structure can be operated more easily. In addition, the fixing structure of the present application can have two first elastic members, and the button is located between the two first elastic members, so that the force on the movable part can be more evenly applied, achieving a more stable fixing effect.

[0080] Please refer to Figure 2 . Figure 2 3D is a perspective view of an electronic assembly 10 according to an embodiment of the present 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 member 210 disposed on the periphery of the housing 205. The fixing structure 100 is configured to abut against the extension member 210 of the processing module 200 to prevent the processing module 200 from falling off the frame 300.

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

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

[0083] The structure and function of each component included in the fixing structure 100 of this embodiment and the connection relationship between the components will be described in detail below.

[0084] Please also refer to Figure 3 and Figure 4 . Figure 3 It is a three-dimensional diagram of a fixing structure 100 according to an embodiment of the present application. Figure 4 FIG. 1 is an exploded view of a fixing structure 100 according to an embodiment of the present application. In this embodiment, the fixing structure 100 includes a fixing portion 110, a movable portion 120, a button 130, a first elastic member 140, and a second elastic member 150. In order to clearly illustrate the positions of the components, Figure 3The movable part 120 in the figure is transparent and its outline is indicated by a dotted line. The fixed part 110 is connected to the movable part 120 in a sliding manner along the direction x. In more detail, the fixed part 110 has two opposite 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 connected to the two protrusions 124 in a sliding manner along the direction x, respectively. In other words, the protrusions 124 are configured to slide relative to the sliding grooves 114 along the direction x. The fixed part 110 has a through hole 116. The button 130 passes through the through hole 116 and is connected to the fixed part 110 in a sliding manner in the direction y. The button 130 is configured to be selectively coupled to or detached from the movable part 120 by pressing. The 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 are respectively in contact with the fixed part 110 and the movable part 120. The second elastic member 150 is disposed between the button 130 and the fixed part 110. Two ends of the second elastic member 150 abut against the fixing portion 110 and the button 130 respectively.

[0085] In some embodiments, the first elastic member 140 and the second elastic member 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 portion 110 has a positioning hole 112 . The positioning hole 112 is used to correspond to the positioning column 302 . The positioning column 302 passes through the positioning hole 112 to fix the fixing portion 110 on the frame 300 .

[0087] Please refer to Figure 5 . Figure 5 FIG. 1 is a perspective view of a fixing structure 100 according to an embodiment of the present application. For the sake of clarity, Figure 5 The fixed portion 110 is transparent and its outline is indicated by a dotted line. In this embodiment, the movable portion 120 has two receiving grooves 122 for receiving two first elastic members 140. The two receiving grooves 122 are respectively located on opposite sides of the button 130 along the direction y. 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 direction y. Such a structural design can make the force on the movable portion 120 more uniform when the first elastic member 140 returns to push against the movable portion 120 through its own elastic force.

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

[0089] Please continue to refer to Figure 5 . In this embodiment, the movable part 120 includes a first meshing portion 126 and abutting surface 128. The butting surface 128 is located on a side of the movable part 120 away from the fixed part 110. The butting surface 128 abuts against the processing module 200. The button 130 includes a second meshing portion 136. The first meshing portion 126 and the second meshing portion 136 are engaged with each other along the direction x, so that the movable part 120 and the button 130 are combined so as not to slide relative to each other in the direction x. In some embodiments, the second meshing portion 136 is on the receiving groove 122.

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

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

[0092] Please also refer to Figure 5 as well as Figure 6 . Figure 6 FIG. 1 is a perspective view of a fixing structure 100 according to an embodiment of the present application. In this embodiment, the button 130 is configured to receive a pressing force F1 from a direction y. The pressing force F1 causes the button 130 to slide along the direction y (see FIG. 1 ). Figure 6 ). When the button 130 slides along the direction y, the second meshing portion 136 slides along the direction y relative to the first meshing portion 126, so that the first meshing portion 126 is separated from the second meshing portion 136. When the button 130 slides along the direction y, the second elastic member 150 is compressed along the direction y. When the first meshing portion 126 of the movable portion 120 is separated from the second meshing portion 136 of the button 130, the first elastic member 140 returns to push against the movable portion 120 by its own elastic force, so that the movable portion 120 slides along the direction x away from the fixed portion 110.

[0093] Please refer to Figure 6 and Figure 7 . Figure 7 In some embodiments, when the button 130 stops receiving the pressing force F1 along the direction y, the second elastic member 150 can push the button 130 by its own elastic force, so that the button 130 is restored to its original position along the opposite direction of the direction y.

[0094] Please refer to Figure 5 and Figure 7 . Figure 5 Compared with the embodiment of Figure 7 In the embodiment, the first engagement portion 126 and the second engagement portion 136 have different engagement positions in the direction x. More precisely, after the button 130 is pressed, the button 130 is separated from the movable portion 120, so that the first engagement portion 126 moves away from the fixed portion 110 and the button 130 along the direction x. Therefore, when the button 130 is restored to its original position along the direction y by the second elastic member 150, the second engagement portion 136 is engaged with a portion of the first engagement portion 126 that is farther away from the abutting surface 128.

[0095] Through the above-mentioned structural configuration, in a use scenario, when the button 130 is subjected to the pressing force F1 and moves relative to the fixed portion 110, the second engagement portion 136 of the button 130 is disengaged from the first engagement portion 126 of the movable portion 120, so that the first elastic member 140 is elastically restored, and the movable portion 120 moves in the direction x away from the fixed portion 110 and abuts against the processing module 200, thereby achieving the purpose of fixing the processing module 200. Then, when the button 130 is no longer subjected to the pressing force F1 and the elastic force of the second elastic member 150 is restored (such as Figure 7 As shown in FIG. 1 ), the movable portion 120 can be prevented from moving again, thereby achieving the purpose of stably fixing the electronic component.

[0096] In some embodiments, the direction of the pressing force (e.g., direction y) is perpendicular to the direction in which the movable portion 120 slides away from the fixed portion 110 (e.g., direction x). In some embodiments, the button 130 and the first elastic member 140 are arranged along direction z (e.g., in direction z, the button 130 is located between the two first elastic members 140). Direction x, direction y, and direction z are perpendicular to each other. In some embodiments, the direction in which the elastic force of the first elastic member 140 returns (e.g., direction y) is perpendicular to the direction in which the elastic force of the second elastic member 150 returns (e.g., direction x). In some embodiments, the direction in which the button 130 slides back and forth (e.g., direction y) is parallel to the direction in which the second elastic member 150 is compressed by the pressing force. Since the sliding direction of the button 130 is the same as the elastic compression direction of the second elastic member 150, the method of pressing the button 130 can be made more labor-saving and easy to press.

[0097] The following will describe in detail the manner in which the fixing structure 100 of the present application fixes the processing module 200 .

[0098] Please refer to Figure 8 . Figure 8 FIG. 1 is a top view of a fixing structure 100 and a processing module 200 according to an embodiment of the present application. Figure 8The frame 300 and the top cover 400 are omitted. In this embodiment, the processing module 200 includes a box body 205 and an extension member 210. The movable portion 120 of the fixed structure 100 faces the extension member 210 in the direction x. There is a distance D1 between the movable portion 120 and the extension member 210 in the direction x. The distance D1 may vary depending on the specifications or dimensions of the processing module 200.

[0099] In some embodiments, since the processing module 200 is larger (eg, the extension member 210 is longer), the distance D1 may be 0 before pressing the button 130. In other words, before the fixing structure 100 is actuated, the extension member 210 may abut against the abutting surface 128 of the movable portion 120.

[0100] Please refer to Fig. 9 . Fig. 9 for Figure 8 A cross-sectional view of the fixing structure 100 and the processing module 200 observed along the cutting line 9-9. In the present embodiment, the second elastic member 150 is disposed in the receiving groove 132 of the button 130. The movable portion 120 and the extension member 210 have a distance D1 in the direction x. The first engaging portion 126 includes a plurality of first serrations 1261. The first engaging portion 126 includes a plurality of first grooves 1262 defined by the first serrations 1261. The second engaging portion 136 of the button 130 further includes a plurality of second serrations 1361, and the second engaging portion 136 includes a plurality of second grooves 1362 defined by the second serrations 1361. The first serration 1261 is configured to engage with the second groove 1362. The second serration 1361 is configured to engage with the first groove 1262. The first serration 1261 includes a first vertical surface 1261a and a first inclined surface 1261b. The second sawtooth 1361 includes a second vertical surface 1361 a and a second inclined surface 1361 b .

[0101] In some alternative embodiments, the first sawtooth 1261 may include two vertical surfaces extending in parallel and a plane connecting the two vertical surfaces. The second sawtooth 1361 may also include two vertical surfaces extending in parallel and a plane connecting the two vertical surfaces. Accordingly, the first sawtooth 1261 and the second sawtooth 1361 may be engaged more stably.

[0102] In some embodiments, Fig. 9 As shown, the first vertical surface 1261a is located on the side of the first sawtooth 1261 close 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 away 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 away 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 close to the fixed portion 110 and faces the fixed portion 110.

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

[0104] Please also refer to Figure 8 , Fig.10 and Fig.11 . Fig.10 It is a top view of a fixing structure 100 fixing a processing module 200 according to one embodiment of the present application. Fig.11 for Fig.10 11-11 is a cross-sectional view of the fixed structure 100 and the processing module 200. In this embodiment, by pressing the button 130, the movable part 120 moves along the direction x and abuts against the extension member 210. In more detail, the button 130 is configured to be able to separate from the movable part 120 under the action of the pressing force along the direction y. After the first meshing part 126 and the second meshing part 136 are separated, the movable part 120 moves along the direction x so that the abutting surface 128 abuts against the extension member 210 (such as Fig.10 , Fig.11 As shown), the processing module 200 is fixed. In other words, after the movable portion 120 moves along the direction x, Figure 8 The distance D1 shown in FIG. 1 is substantially zero.

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

[0106] In some embodiments, the movable portion 120 can move relative to the fixed portion 110 by a distance of approximately 4.5 mm. The distance that the movable portion 120 can move relative to the fixed portion 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 that the movable portion 120 can slide relative to the fixed portion 110 can be adjusted according to the size of different processing modules 200 that may need to be fixed, and the present application is not limited thereto.

[0107] In one embodiment of the present application, the fixed structure of the present application can be set in a server, and the server can be used for artificial intelligence (AI) computing, edge computing, and can also be used as a 5G server, cloud server or Internet of Vehicles server.

[0108] In summary, since the button of the fixed structure of the present application moves in the same direction as the direction of elastic compression of the second elastic member under the pressing force, the button can easily slide relative to the fixed member. In addition, since the present application has multiple first elastic members and the first elastic members are located on opposite sides of the button, a more even abutting force can be provided, so that the movable part can stably abut against the extension member without jumping. In addition, since the fixed structure of the present case includes a movable part, it can well solve the tolerance problem between processing modules of different specifications, so that the fixed structure can correspond to different brands, which can greatly reduce the cost required for development.

[0109] The foregoing description is provided only to illustrate and describe exemplary embodiments of the present application and is not intended to be exhaustive or to limit the precise form of the invention disclosed in the present application. The above teachings may be modified or varied.

[0110] The embodiments selected and described are intended to explain the content of the present application and their practical application so as to inspire other persons skilled in the art to utilize the present application and various embodiments, and to make various modifications to meet the expected specific use. Without departing from the spirit and scope of the present application, alternative embodiments will be obvious to those skilled in the art to which the present application belongs. Therefore, the scope of the present application is determined according to the attached invention claims, rather than being limited by the foregoing description and the exemplary embodiments described therein.
