Abstract
Description
Technical Field
[0001] The present application relates to the field of expansion module data processing equipment, and in particular to an expansion module fixing device, a mainboard and an electronic device. Background Art
[0002] The expansion module includes a circuit board with memory, a memory stick, a graphics card adapter card, etc. In order to better exert the performance of the expansion module, various operations are performed on the expansion module, such as temperature detection, heating, cooling, etc. Such operations require the functional parts to contact the expansion module to perform corresponding operations on the expansion module. In the related art, the functional parts are directly fixed to the expansion module, but because the expansion module needs to be plugged in and out, each time the expansion module is plugged in and out, the functional parts need to be re-fixed to the expansion module, which is inconvenient to operate. Summary of the invention
[0003] In view of this, it is necessary to provide an expansion module fixing device, a mainboard and an electronic device that are easy to operate.
[0004] An embodiment of the present application provides an expansion module fixing device, the expansion module fixing device comprising a base, a bracket and a functional part. The base is provided with a slot for installing the expansion module, and the base has a length direction. The bracket is rotatably connected to the base, and the rotation axis of the bracket extends in a length direction parallel to the base. The bracket is provided with a rebound structure, and the rebound structure is configured so that when the bracket rotates away from the base, the rebound structure elastically deforms and applies a force toward the base to the bracket. The functional part is arranged on the bracket for contacting the expansion module.
[0005] In the expansion module fixing device of the above embodiment, the bracket has a first state and a second state, the functional part is arranged on the bracket, and the rebound structure allows the bracket to be in the first state, so that the functional part can directly contact the expansion module, so as to facilitate various operations on the expansion module. When the expansion module needs to be plugged in or out, the bracket can be rotated so that the bracket is in the second state, and then the expansion module is plugged in or out. After the expansion module is installed in the slot, the bracket is returned to the first state through the rebound structure so that the functional part contacts the expansion module. The operation process of contacting or separating the functional part from the expansion module is simple and convenient.
[0006] In at least one embodiment, the bracket is provided with an avoidance groove, the rebound structure is a spring sheet, the spring sheet is located in the avoidance groove, the spring sheet is arranged in an arc shape, one end of the spring sheet is connected to the groove wall of the avoidance groove, and the other end is in contact with the base.
[0007] In the expansion module fixing device of the above embodiment, the spring sheet allows the bracket to maintain moderate stability in the first state, reducing the elastic force of the spring sheet on the bracket to be too large, resulting in the bracket and the expansion module squeezing the functional part or the functional part impacting the expansion module when the bracket returns from the second state to the first state, resulting in damage to the functional part or the expansion module. It can also reduce the elastic force of the spring sheet on the bracket to be too small, resulting in insufficient fit between the functional part and the expansion module.
[0008] In at least one embodiment, the base includes a socket and two fixing parts. The slot is located in the socket. The two fixing parts are spaced apart and rotatably connected to opposite ends of the socket, and the rotation axis of the fixing part is perpendicular to the length direction of the bracket and the plug-in and pull-out direction of the expansion module; the fixing part is used to limit the position of the expansion module, and the fixing part is configured to release the position limit of the expansion module when the fixing part rotates away from the other fixing part, and the fixing part drives the bracket to rotate away from the socket.
[0009] In the expansion module fixing device of the above embodiment, when the position limitation of the expansion module is released, it is often necessary to pull out the expansion module. When the fixing part moves to the unlocked state, it can also drive the bracket to move to the second state, so that the functional part is separated from the expansion module, so as to facilitate pulling out the expansion module.
[0010] In at least one embodiment, two guide blocks are provided on one side of the bracket close to the base, the two guide blocks are adjacent to the two fixed parts, each guide block is in contact with the corresponding fixed part, and the thickness of the guide block gradually increases along the direction in which the guide block moves away from the other guide block, and the thickness direction of the guide block is parallel to the rotation axis of the fixed part.
[0011] In the expansion module fixing device of the above embodiment, the fixing part has a fixed state and an unlocked state. When the fixing part rotates from the locked state to the unlocked state, the fixing part pushes the guide block. As the thickness of the guide block gradually increases, the bracket can gradually rotate away from the base, and then the bracket rotates from the first state to the second state. The process of switching the bracket from the first state to the second state is simple and convenient.
[0012] In at least one embodiment, along the direction in which the guide block moves away from another guide block, the guide block is arranged to be inclined downward.
[0013] In the expansion module fixing device of the above embodiment, the guide block is inclined so as to facilitate avoiding other structures.
[0014] In at least one embodiment, the fixing portion is located in the slot, the fixing portion is provided with a snap-fit structure, a slot wall of the slot is provided with a snap-fit groove, and the snap-fit structure is located in the snap-fit groove.
[0015] In the expansion module fixing device of the above embodiment, by providing the cooperation between the clamping structure and the clamping slot, the fixing portion can be stably maintained in a fixed state, so as to limit the position of the expansion module.
[0016] In at least one embodiment, the clamping structure includes a first clamping block and a second clamping block, the first clamping block and the second clamping block are arranged at an interval, and the first clamping block is located above the second clamping block and close to one side of the other fixing portion. The clamping slot has a first part and a second part, the first clamping block is located in the first part, and the second clamping block is located in the second part.
[0017] In the expansion module fixing device of the above embodiment, the first clamping block is located in the first part, and the second clamping block is located in the second part. The two positions define the position of the fixing part, which can improve the stability of the fixing part.
[0018] In at least one embodiment, along the direction from the fixing portion toward the other fixing portion, the height of the first card block and the second card block gradually decreases, and the height direction of the first card block and the second card block is parallel to the plugging direction of the expansion module. Along the length direction of the base, the thickness of both sides of the first card block and the second card block gradually increases toward the middle, and the thickness direction of the first card block and the second card block is parallel to the extension direction of the rotation axis of the fixing portion.
[0019] In the expansion module fixing device of the above embodiment, when the fixing part moves from the unlocked state to the fixed state, since the height of the first card block and the second card block on the side close to the plug-in part is small, it is convenient for the first card block to extend into the first part and the second card block to extend into the second part. When the fixing part is in the fixed state, since the height of the first card block and the second card block on the side away from the plug-in part is large, it can reduce the occurrence of the first card block detaching from the first part and the second card block detaching from the second part due to the rotation of the fixing part due to an accidental touch. The thickness of both sides of the first card block and the second card block is small, which can facilitate the extension into the corresponding first part and the second part, or detachment from the corresponding first part and the second part. The large thickness in the middle can improve the stability of the first card block and the second card block, and can reduce the occurrence of the first card block detaching from the first part and the second card block detaching from the second part due to the rotation of the fixing part due to an accidental touch.
[0020] In at least one embodiment, the functional component is a temperature sensor for detecting the temperature of the expansion module.
[0021] In the expansion module fixing device of the above embodiment, the temperature sensor contacts the expansion module to detect the temperature of the expansion module in real time, so as to understand the current state of the expansion module in real time and to cool the expansion module in time.
[0022] An embodiment of the present application further provides a mainboard, including a circuit board, wherein the mainboard further includes an expansion module fixing device, and the expansion module fixing device is arranged on the mainboard.
[0023] An embodiment of the present application also provides an electronic device, including a mainboard.
[0024] In the expansion module fixing device, mainboard and electronic device of the present application, the bracket is rotatably connected to the base so that the bracket can be in a first state and a second state. The bracket can be switched from the first state to the second state by pushing the guide block by the fixing part. The bracket can be switched from the second state to the first state by the rebound structure. The bracket can switch between the first state and the second state simply and quickly. When the bracket is in the first state, the functional parts arranged on the bracket can contact with the expansion module to facilitate temperature detection, heating, cooling and other operations on the expansion module. When the bracket is in the second state, the functional parts are separated from the expansion module to facilitate plugging and unplugging of the expansion module. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0074] Some embodiments of the present application provide an expansion module fixing device, the expansion module fixing device comprising a base, a bracket and a functional part. The base is provided with a slot for installing the expansion module, and the base has a length direction. The bracket is rotatably connected to the base, and the rotation axis of the bracket extends in a length direction parallel to the base, and the bracket is provided with a rebound structure, and the rebound structure is configured so that when the bracket rotates away from the base, the rebound structure elastically deforms and applies a force toward the base to the bracket. The functional part is arranged on the bracket for contacting the expansion module.
[0075] In the expansion module fixing device of the above embodiment, the bracket has a first state and a second state, the functional part is arranged on the bracket, and the rebound structure allows the bracket to be in the first state, so that the functional part can directly contact the expansion module, so as to facilitate various operations on the expansion module. When the expansion module needs to be plugged in or out, the bracket can be rotated so that the bracket is in the second state, and then the expansion module is plugged in or out. After the expansion module is installed in the slot, the bracket is returned to the first state through the rebound structure so that the functional part contacts the expansion module. The operation process of contacting or separating the functional part from the expansion module is simple and convenient.
[0076] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.
[0077] See also Figure 1 An embodiment of the present application provides an electronic device 1, the electronic device 1 includes a mainboard 1000 and a housing 2000, and the mainboard 1000 is located in the housing 2000. The electronic device 1 includes but is not limited to a computer host, a server, and the like.
[0078] See also Figure 2 The mainboard 1000 includes a circuit board 200 and an expansion module fixing device 100 disposed on the circuit board 200. The expansion module fixing device 100 is used to fix the expansion module 300 so that the expansion module 300 can store data.
[0079] Optionally, a plurality of expansion module fixing devices 100 are disposed on each mainboard 1000 , and the plurality of expansion module fixing devices 100 are arranged in an array.
[0080] See also Figure 3 , Figure 4 and Figure 5, each expansion module fixing device 100 includes a base 10, a bracket 20 and a functional part 30. In order to more clearly describe the technical solutions of each embodiment of the present application, a coordinate system is established in the figure, and the subsequent description of each orientation of the expansion module fixing device 100 is based on the coordinate system. The X-axis is the length direction of the base 10, the Y-axis is perpendicular to the X-axis in the horizontal plane, the Z-axis is perpendicular to the plane formed by the X-axis and the Y-axis, and the plug-in and unplug direction of the expansion module 300 is parallel to the Z-axis. It should be noted that the establishment of the coordinate system is only for the convenience of explanation, and the coordinate system is only relative to the structure in the figure.
[0081] The base 10 is provided with a slot 113, and the expansion module 300 can be installed in the slot 113 to achieve the connection between the expansion module 300 and the expansion module fixing device 100. Optionally, the expansion module 300 can transmit and store data. The bracket 20 is rotatably connected to the base 10, and the rotation axis O1 of the bracket 20 is parallel to the X axis. The bracket 20 has a first state and a second state. When the bracket 20 is in the first state, the bracket 20 is generally vertically arranged. When the bracket 20 rotates from the first state toward a direction away from the base 10, it can reach the second state. When the bracket 20 is in the second state, it is inclined relative to the Z axis. The bracket 20 is provided with a rebound structure 21. The rebound structure 21 is configured so that when the bracket 20 rotates from the first state toward a direction away from the base 10 to the second state, the rebound structure 21 is elastically deformed and a force is applied to the bracket 20 toward the base 10, so that the bracket 20 can return to the first state from the second state. The functional component 30 is disposed on the bracket 20. When the bracket 20 is in the first state, the functional component 30 contacts the expansion module 300, so that the functional component 30 can detect the temperature, increase the temperature, and reduce the temperature of the expansion module 300. When the bracket 20 is in the second state, the functional component 30 is separated from the expansion module 300, so that when the expansion module 300 is plugged in or out, the expansion module 300 and the functional component 30 do not contact each other, thereby reducing the occurrence of the expansion module 300 scratching the functional component 30.
[0082] It should be noted that the bracket 20 has a first state and a second state. If there is no special description, the description of the expansion module fixing device 100 assumes that the bracket 20 is in the first state.
[0083] The functional component 30 is arranged on the bracket 20, and the rebound structure 21 allows the bracket 20 to be in the first state, so that the functional component 30 can directly contact the expansion module 300, so as to facilitate various operations on the expansion module 300. When the expansion module 300 needs to be plugged in or out, the bracket 20 can be rotated to put the bracket 20 in the second state, and then the expansion module 300 can be plugged in or out. After the expansion module 300 is installed in the slot 113, the bracket 20 is returned to the first state through the rebound structure 21, so that the functional component 30 is in contact with the expansion module 300. The operation process of the functional component 30 contacting or separating with the expansion module 300 is simple and convenient.
[0084] See also Figure 5 and Figure 6 In some embodiments, the base 10 includes a socket 11 and two fixing parts 12. The socket 11 extends along the X-axis direction, and the slot 113 is located in the socket 11. The two fixing parts 12 are arranged at intervals along the X-axis and are located at opposite ends of the socket 11. The fixing parts 12 are rotatably connected to the socket 11, and the rotation axis O2 of the fixing part 12 is perpendicular to the length direction of the bracket 20 and the plug-in and pull-out direction of the vertical expansion module 300, that is, the rotation axis O2 of the fixing part 12 extends along the Y-axis direction.
[0085] The fixing portion 12 has a fixed state and an unlocked state. When the fixing portion 12 is in the fixed state, the fixing portion 12 extends substantially along the Z axis, and the fixing portion 12 can limit the position of the expansion module 300. When the fixing portion 12 rotates in a direction away from the other fixing portion 12, it can switch from the fixed state to the unlocked state, at which time the position limit of the expansion module 300 is released.
[0086] It should be noted that the fixing portion 12 has a fixed state and an unlocked state. If there is no special description, the description of the expansion module fixing device 100 assumes that the fixing portion 12 is in the fixed state.
[0087] See also Figure 6 and Figure 7 The socket 11 includes a plug-in portion 111 and two connecting portions 112. The plug-in portion 111 extends along the X-axis. The two connecting portions 112 are connected to opposite ends of the plug-in portion 111 along the X-axis. The slot 113 is located on the plug-in portion 111 and the two connecting portions 112. The fixing portion 12 is rotatably connected to the connecting portion 112. The bracket 20 is rotatably connected to the two connecting portions 112. Along the Z-axis direction, the width of the plug-in portion 111 is smaller than the height of the connecting portion 112, so that the shape of the socket 11 is roughly U-shaped.
[0088] See also Figure 7 and Figure 8 In some embodiments, the fixing portion 12 is located in the slot 113 formed by the connecting portion 112, the fixing portion 12 is provided with a snap-fit structure 125, the slot wall of the slot 113 is provided with a snap-fit groove 114, and the position of the snap-fit groove 114 is located in the connecting portion 112. The snap-fit structure 125 is located in the snap-fit groove 114 to limit the position of the fixing portion 12.
[0089] By providing the engagement structure 125 and the engagement slot 114 , the fixing portion 12 can be stably maintained in a fixed state, so as to limit the position of the expansion module 300 .
[0090] In some embodiments, the clamping structure 125 includes a first clamping block 1251 and a second clamping block 1252. The first clamping block 1251 and the second clamping block 1252 are arranged at intervals. Along the Z-axis direction, the first clamping block 1251 is located above the second clamping block 1252. Along the X-axis direction, the first clamping block 1251 is located on a side of the second clamping block 1252 close to another fixing portion 12. The clamping slot 114 has a first portion 1141 and a second portion 1142. Along the X-axis direction, the first portion 1141 is located on a side of the second portion 1142 close to the plug-in portion 111. The first clamping block 1251 is located in the first portion 1141, and the second clamping block 1252 is located in the second portion 1142.
[0091] The first clamping block 1251 is located at the first part 1141, and the second clamping block 1252 is located at the second part 1142. The two positions define the position of the fixing part 12, which can improve the stability of the fixing part 12. When the fixing part 12 is rotated to the unlocked state, the first clamping block 1251 is separated from the first part 1141, and the second clamping block 1252 is separated from the second part 1142.
[0092] Optionally, the number of the first block 1251 and the second block 1252 are both two and are located at opposite sides of the fixing portion 12 along the Y axis. The number of the first portion 1141 and the second portion 1142 are also two and are located on the slot wall of the slot 113 spaced apart along the Y axis.
[0093] See also Figure 8 In some embodiments, along the direction of the fixing portion 12 toward the other fixing portion 12, the heights of the first card block 1251 and the second card block 1252 gradually decrease, and the height direction of the first card block 1251 and the second card block 1252 is parallel to the plug-in direction of the expansion module 300, that is, parallel to the Z-axis direction.
[0094] When the fixing portion 12 moves from the unlocked state to the fixed state, since the heights of the first card block 1251 and the second card block 1252 close to the plug-in portion 111 are small, the first card block 1251 can be easily inserted into the first portion 1141 and the second card block 1252 can be easily inserted into the second portion 1142 .
[0095] When the fixing portion 12 is in a fixed state, since the height of the first card block 1251 and the second card block 1252 away from the plug-in portion 111 is large, the fixing portion 12 can be reduced from rotating due to accidental touch, causing the first card block 1251 to detach from the first part 1141, and the second card block 1252 to detach from the second part 1142.
[0096] In some embodiments, along the length direction of the base 10, that is, along the X-axis direction, the thickness of both sides of the first block 1251 and the second block 1252 gradually increases toward the middle, and the thickness direction of the first block 1251 and the second block 1252 is parallel to the extension direction of the rotation axis O2 of the fixed part 12, that is, the thickness of the first block 1251 and the second block 1252 is parallel to the Y-axis direction.
[0097] The first clamping block 1251 and the second clamping block 1252 have small thicknesses on both sides, so that they can easily be inserted into the corresponding first part 1141 and the second part 1142, or separated from the corresponding first part 1141 and the second part 1142. The thickness in the middle is large, so that the stability of the first clamping block 1251 and the second clamping block 1252 can be improved, and the occurrence of the first clamping block 1251 separating from the first part 1141 and the second clamping block 1252 separating from the second part 1142 due to the rotation of the fixing part 12 caused by accidental touch can be reduced.
[0098] In some embodiments, along the Y-axis direction, the slope of the first card block 1251 and the second card block 1252 near the plug-in portion 111 is smaller than the slope of the first card block 1251 and the second card block 1252 away from the plug-in portion 111. This facilitates the first card block 1251 and the second card block 1252 to extend into the corresponding first portion 1141 and the second portion 1142, and improves the stability of the first card block 1251 and the second card block 1252 located at the corresponding first portion 1141 and the second portion 1142.
[0099] See also Figure 7 and Figure 8 In some embodiments, a buckle groove 124 is provided on one side of the two fixing portions 12 close to each other, and the expansion module 300 is at least partially located in the buckle groove 124 , thereby limiting the position of the expansion module 300 .
[0100] The fixing portion 12 includes a handle 121, a limit block 122 and a push block 123. The handle 121 is fixed above the limit block 122. The buckle slot 124 is located at the handle 121 and the limit block 122. The clamping structure 125 is located at two opposite sides of the limit block 122. The limit block 122 is rotatably connected to the connecting portion 112. The push block 123 is arranged at the lower end of the limit block 122.
[0101] When the fixing portion 12 is in the fixed state, the expansion module 300 is at least partially located in the buckle groove 124, and the push block 123 is located at the bottom of the expansion module 300. When the fixing portion 12 is switched from the fixed state to the unlocked state, the push block 123 rotates and lifts the expansion module 300, so that while contacting the expansion module 300 to limit the position, the expansion module 300 also moves upward, so that the expansion module 300 is easily pulled out.
[0102] When the expansion module 300 is inserted, the bottom of the expansion module 300 pushes the push block 123 to rotate the fixing portion 12 from the unlocked state to the fixed state, thereby limiting the expansion module 300. The process of limiting the expansion module 300 by the fixing portion 12 is simple and convenient.
[0103] See also Fig. 9 , Fig.10 and Fig.11 In some embodiments, the fixing portion 12 is configured to release the position limitation of the expansion module 300 when the fixing portion 12 rotates in a direction away from another fixing portion 12 , and the fixing portion 12 drives the bracket 20 to rotate in a direction away from the socket 11 .
[0104] When the position limit of the expansion module 300 is released, it is often necessary to pull out the expansion module 300. When the fixing portion 12 moves to the unlocked state, it can also drive the bracket 20 to move to the second state, so that the functional part 30 is separated from the expansion module 300, so as to facilitate the pull-out of the expansion module 300.
[0105] By rotating the fixing portion 12 , the expansion module 300 can be unlocked, the expansion module 300 can be lifted, and the bracket 20 can be driven to move to the second state. One action can achieve multiple effects, which can improve the convenience of operation.
[0106] In some embodiments, two guide blocks 24 are provided on one side of the bracket 20 close to the base 10, and the two guide blocks 24 are adjacent to the two fixing parts 12. Each guide block 24 contacts the stop block 122 of the corresponding fixing part 12, and the thickness of the guide block 24 gradually increases along the direction in which the guide block 24 moves away from the other guide block 24. The thickness direction of the guide block 24 is parallel to the rotation axis O2 of the fixing part 12, that is, parallel to the Y-axis direction.
[0107] During the process of the fixing portion 12 rotating from the locked state to the unlocked state, the fixing portion 12 pushes the guide block 24. As the thickness of the guide block 24 gradually increases, the bracket 20 can gradually rotate away from the base 10, and then the bracket 20 rotates from the first state to the second state. The process of switching the bracket 20 from the first state to the second state is simple and convenient.
[0108] In some embodiments, along the direction in which the guide block 24 moves away from another guide block 24 , the guide block 24 is arranged to be inclined downward.
[0109] The guide block 24 is arranged at an angle, and the first clamping block 1251 and the second clamping block 1252 are arranged at intervals, so that the guide block 24, the first clamping block 1251 and the second clamping block 1252 will not interfere with each other, and the width of the guide block 24 along the Z-axis direction can be maintained at an optimal length to reduce the scratching of the limit block 122 when the guide block 24 contacts the limit block 122 of the fixed part 12.
[0110] The bracket 20 is in the shape of an elongated strip and has a large size to facilitate installation of the functional component 30. The two ends of the bracket 20 are rotatably connected to the two connecting parts 112 of the base 10, so that the bracket 20 can be switched between the first state and the second state.
[0111] See also Fig. 9 and Fig.12 In some embodiments, the bracket 20 is provided with an avoidance groove 22, the rebound structure 21 is a spring sheet 211, the spring sheet 211 is located in the avoidance groove 22, the spring sheet 211 is arranged in an arc shape, and one end is connected to the groove wall of the avoidance groove 22, and the other end is in contact with the base 10.
[0112] When the bracket 20 is in the second state, the spring piece 211 undergoes elastic deformation and applies an elastic restoring force toward the base 10 to the bracket 20, so that when the fixing portion 12 is in the fixed state, the spring piece 211 can drive the bracket 20 to rotate to the first state so that the functional part 30 can contact the expansion module 300.
[0113] Optionally, there are multiple avoidance grooves 22 , and the multiple avoidance grooves 22 are arranged at intervals along the X-axis direction, and each avoidance groove 22 is provided with a spring piece 211 .
[0114] The bracket 20 can be automatically rebounded from the second state to the first state by providing the spring piece 211. Since the spring piece 211 and the guide block 24 are both provided on the bracket 20, the structural change of the base 10 is small, and the expansion module fixing device 100 can be improved on the products in the related art without additional re-production, so as to reduce costs.
[0115] The spring sheet 211 allows the bracket 20 to maintain moderate stability in the first state, and reduces the elastic force of the spring sheet 211 on the bracket 20, which may cause the bracket 20 and the expansion module 300 to squeeze the functional part 30 or the functional part 30 to impact the expansion module 300 when the bracket 20 returns from the second state to the first state, resulting in damage to the functional part 30 or the expansion module 300. It can also reduce the elastic force of the spring sheet 211 on the bracket 20, which may cause insufficient fit between the functional part 30 and the expansion module 300.
[0116] In some embodiments, the lower end of the arc-shaped elastic sheet 211 is folded upward, so that the lower end of the elastic sheet 211 has two layers.
[0117] It is understandable that the rebound structure 21 is not limited to the spring sheet 211. In some other embodiments, the rebound structure 21 is a torsion spring, which is disposed at both ends of the bracket 20. The torsion spring has a long service life.
[0118] See also Figure 6 and Fig. 9In some embodiments, the bracket 20 is provided with two through slots 23, the two through slots 23 are spaced apart along the X-axis direction, a portion of the functional component 30 is provided on a side of the bracket 20 away from the base 10, and the functional component 30 is passed through the two through slots 23, so that another portion of the functional component 30 can be located on a side of the bracket 20 close to the base 10. The functional component 30 located on the side of the bracket 20 close to the base 10 can contact the expansion module 300.
[0119] Since the functional component 30 usually needs to connect to the circuit, by providing two through slots 23, most of the functional component 30 is located on the side of the bracket 20 away from the base 10, which can increase the installation space of the functional component 30, and the functional component 30 is inserted into the through slot 23, so that the functional component 30 can be positioned.
[0120] In some embodiments, the portion of the bracket 20 located between the two through slots 23 protrudes toward the base, so as to improve the fit between the functional component 30 and the expansion module 300 .
[0121] In some embodiments, the expansion module fixing device 100 further includes a flexible body 40, which is disposed on a side of the bracket 20 close to the base 10 and between the two through slots 23. The functional component 30 contacts a side of the flexible body 40 away from the bracket 20, so that the functional component 30 can better fit the expansion module 300. Optionally, the flexible body 40 is a sponge.
[0122] In some embodiments, the bracket 20 is further provided with a buckle, which can buckle the circuit of the functional component 30 .
[0123] In some embodiments, the functional component 30 is a temperature sensor, which is in direct contact with the expansion module 300 to measure the temperature of the expansion module 300 .
[0124] In other embodiments, the functional component 30 is a heating module for heating the expansion module 300 .
[0125] In other embodiments, the functional component 30 is a cooling module for reducing the temperature of the expansion module 300 .
[0126] In some embodiments, the expansion module 300 is a DIMM (Dual-Inline-Memory-Modules) memory. Two opposite ends of the expansion module 300 are provided with grooves, which cooperate with the fixing portion 12 to define the position of the expansion module 300 .
[0127] In summary, an expansion module fixing device 100, a mainboard 1000 and an electronic device 1 are provided in an embodiment of the present application. By setting a bracket 20 to be rotatably connected with the base 10, the bracket 20 can be in a first state and a second state. The bracket 20 can be switched from the first state to the second state by pushing the guide block 24 by the fixing portion 12. The bracket 20 can be switched from the second state to the first state by the rebound structure 21. The bracket 20 can switch between the first state and the second state simply and quickly. When the bracket 20 is in the first state, the functional part 30 arranged on the bracket 20 can contact the expansion module 300, so as to perform temperature detection, heating, cooling and other operations on the expansion module 300. When the bracket 20 is in the second state, the functional part 30 is separated from the expansion module 300, so as to facilitate the plugging and unplugging of the expansion module 300.
[0128] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
