Description

Technical Field

[0001] This application relates to the technical field of electronic device accessories, and particularly to a locking member and an electronic device. Background Art

[0002] With the continuous development of technology, on the circuit boards of electronic devices such as personal computers and servers, more and more functional modules need to be installed, such as solid-state drives, wireless transmission modules, etc.

[0003] However, for most current functional modules (such as solid-state drives), they mainly rely on fasteners such as screws to achieve locking connection with the circuit board. And during the installation and disassembly process, corresponding tools must be used to screw the screws, making the installation and disassembly operations of the functional modules inconvenient. Summary of the Invention

[0004] Based on this, in view of the inconvenient installation and disassembly operations of functional modules in related technologies, it is necessary to provide a locking member and an electronic device.

[0005] An embodiment of this application provides a locking member for locking a functional module to a circuit board. The locking member includes: a body, a pressing portion, and an elastic positioning portion. The body is rotatably connected to the circuit board about an axis in a first direction; the locking member has a locking position and an unlocking position, and can be switched between the locking position and the unlocking position by rotating the body.

[0006] The pressing portion is connected to the body. When the locking member is in the locking position, the pressing portion presses the functional module in a direction approaching the circuit board along the first direction. When the locking member is in the unlocking position, the pressing portion releases the limitation on the functional module in the first direction.

[0007] The elastic positioning portion is connected to the body and can cooperate with a first positioning structure on the circuit board under the action of an elastic force to position the locking member in the locking position; the elastic positioning portion can be disengaged from the first positioning structure under the action of an external force.

[0008] The above locking member is used to lock the functional module to the circuit board. When the locking member is in the locked position, the pressing portion presses the functional module along the first direction, realizing the limit of the functional module along the first direction. Since the elastic positioning portion can cooperate with the first positioning structure on the circuit board under the action of its own elastic force, the locking member is positioned at the locked position, so that the locking member can reliably limit and fix the functional module along the first direction. By applying an external force to the elastic positioning portion to overcome its elastic force, the elastic positioning portion is disengaged from the first positioning structure, so that the locking member rotates from the locked position to the unlocked position, so that the pressing portion releases the limit of the functional module in the first direction, and then it is convenient to disassemble the functional module from the circuit board. It can be seen that the above locking member can realize the positioning or de-positioning of the locking member at the locked position through the elastic deformation of the elastic positioning portion, and can realize the switching between the locked position and the unlocked position by rotating the locking member, without the aid of other tools, thus facilitating the installation and disassembly of the functional module.

[0009] In an embodiment, when the locking member is in the unlocked position, the elastic positioning portion can cooperate with the second positioning structure on the circuit board under the action of the elastic force, so that the locking member is positioned at the unlocked position; the elastic positioning portion can be disengaged from the second positioning structure under the action of an external force.

[0010] When the functional module needs to be disassembled, after the elastic positioning portion is disengaged from the first positioning structure, the locking member rotates from the locked position to the unlocked position by the rotation of the body. When the locking member rotates to the unlocked position, the elastic positioning portion can cooperate with the second positioning structure on the circuit board under the action of its own elastic force, so that the elastic positioning portion is positioned, and then it is convenient to remind the operator that the locking member is already in the unlocked position.

[0011] In an embodiment, the pressing portion has a pressing surface for pressing the functional module; along the direction in which the locking member rotates from the locked position to the unlocked position, the pressing surface gradually inclines towards the circuit board.

[0012] In this embodiment, along the direction in which the locking member rotates from the locked position to the unlocked position, the pressing surface gradually inclines towards the circuit board. As the locking member rotates from the unlocked position to the locked position, the pressing surface can gradually press the functional module tighter and tighter, which is beneficial to the locking member to lock the functional module more reliably.

[0013] In an embodiment, the body includes:

[0014] A rotating portion, the rotating portion is rotatably disposed in the mounting hole on the circuit board around the axis in the first direction;

[0015] A supporting portion, the supporting portion is connected to one end of the rotating portion, and the supporting portion is connected to the elastic positioning portion; and

[0016] A connecting shaft, two ends of which along the first direction are respectively connected to the supporting portion and the pressing portion;

[0017] The supporting portion and the pressing portion respectively protrude outward from the connecting shaft in the radial direction of the connecting shaft, so that a spacing space for clamping the functional module is formed between the supporting portion and the pressing portion.

[0018] In this embodiment, the support portion and the pressing portion clamp the functional module together, so that the two sides of the functional module along the first direction can be limited respectively, so that the functional module can be fixed more reliably.

[0019] In one embodiment, the locking member further includes a stop portion, which is connected to a side of the pressing portion close to the circuit board; when the locking member is in the locking position, the stop portion abuts against the functional module along the rotation direction of the body.

[0020] When the locking member is in the locking position, the stop portion abuts against the functional module along the rotation direction of the locking member, thereby facilitating timely reminding the operator that the locking member has been rotated into place.

[0021] In one embodiment, the body includes a rotating portion, the rotating portion includes at least two elastic rotating arms arranged around an axis in the first direction and spaced apart from each other, and a limiting portion corresponding to the elastic rotating arms;

[0022] The limiting portion is connected to one end of the elastic rotating arm away from the pressing portion; the limiting portion protrudes from the elastic rotating arm along the direction of the axis away from the first direction; at least two elastic rotating arms can approach each other under the action of external force so that the limiting portion can pass through the mounting hole on the circuit board.

[0023] By applying external force to at least two elastic rotating arms to overcome the elastic force, at least two elastic rotating arms are brought close to each other, so that each limiting portion can be brought close to each other, and then each limiting portion can pass through the mounting hole on the circuit board. In this way, it is convenient to install and remove the limiting portion. When the limiting portion moves out of the mounting hole in the direction close to the pressing portion, the locking member is completely separated from the circuit board. At this time, the functional module is not limited by the locking member in any direction, so that the functional module can be removed more conveniently.

[0024] In one embodiment, a groove is provided on one side of each elastic rotating arm close to the axis in the first direction.

[0025] By providing the groove, the elastic rotating arm can be more easily elastically deformed, so that the elastic rotating arms can be closer together, thereby facilitating the limiting portion to pass through the mounting hole.

[0026] In one embodiment, the rotating portion further includes a protrusion corresponding to the elastic rotating arm, the protrusion is arranged on a side surface of the corresponding elastic rotating arm away from the axis of the first direction, and abuts against a hole wall of the mounting hole on the circuit board.

[0027] The protruding part is arranged on the surface of the elastic rotating arm on the side far from the axis in the first direction and abuts against the hole wall of the mounting hole. In this way, without increasing the radial dimension of the elastic rotating arm, the rotating part can be made to abut against the hole wall of the mounting hole more easily, so that the shaking of the rotating part in the mounting hole can be fully reduced, and then the rotating part can be kept stable in the mounting hole.

[0028] In one embodiment, one end of the elastic positioning part is connected to the body, and the other end of the elastic positioning part has a clamping protrusion; the first positioning structure is a first clamping groove; the elastic positioning part can make the clamping protrusion cooperate with the first clamping groove under the action of elastic force.

[0029] One end of the elastic positioning part is connected to the body, and the other end of the elastic positioning part has a clamping protrusion. Through the elastic deformation of the elastic positioning part, the clamping protrusion is made to cooperate with the first clamping groove, so that it is convenient to position the locking part at the locking position through the elastic positioning part.

[0030] In one embodiment, the extending direction of the pressing part is along a circumferential direction around the axis in the first direction, and the extending angle of the pressing part is greater than or equal to 90° and less than or equal to 180°. In this way, the pressing part can have a longer extending length, so that a larger pressing area can be provided for the functional module as much as possible, which is beneficial to reliably pressing the functional module.

[0031] The embodiment of the present application also provides an electronic device, including a circuit board, a functional module and the locking part according to any one of the above embodiments. The functional module is locked to the circuit board through the locking part.

[0032] In one embodiment, the functional module is a solid-state drive.

[0033] In the above-mentioned electronic device, when the locking part is in the locking position, the pressing part presses the functional module along the first direction to realize the limit of the functional module along the first direction. Since the elastic positioning part can cooperate with the first positioning structure on the circuit board under the action of its own elastic force, the locking part is positioned at the locking position, so that the locking part can reliably limit and fix the functional module along the first direction. By applying an external force to the elastic positioning part to overcome its elastic force, the elastic positioning part is disengaged from the first positioning structure, so that the locking part rotates from the locking position to the unlocking position, so that the pressing part releases the limit of the functional module in the first direction, and then it is convenient to disassemble the functional module from the circuit board. It can be seen that the above-mentioned locking part can realize the positioning or disengagement of the locking part at the locking position through the elastic deformation of the elastic positioning part, and can realize the switching between the locking position and the unlocking position by rotating the locking part, without the aid of other tools, so as to facilitate the installation and disassembly of the functional module.

If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0053] With the continuous development of technology, on the circuit boards of electronic devices such as personal computers and servers, more and more functional modules need to be installed, such as solid-state drives, wireless transmission modules, etc. However, most current functional modules (such as solid-state drives) mainly rely on fasteners such as screws to achieve locking connection with the circuit board. And during the installation and disassembly process, corresponding tools must be used to screw the screws, which makes the installation and disassembly operations of the functional module inconvenient.

[0054] In view of this, an embodiment of this application provides a locking member and an electronic device. The locking member limits the functional module in a first direction when in the locked position. When the locking member is in the unlocked position, the pressing portion releases the limit on the functional module in the first direction. The locking member can achieve positioning or release of the locking member in the locked position through elastic deformation of the elastic positioning portion, and the switching between the locked position and the unlocked position can be achieved by rotating the locking member, without the need to use other tools, thus facilitating the installation and disassembly of the functional module.

[0055] Please refer to Figure 1 and Figure 2 For an embodiment of this application, a locking member 100 is provided, and in combination with Figure 3 and Figure 4, the locking member 100 is used to lock the functional module 200 to the circuit board 300. For the convenience of describing the technical solution of the present application below, the first direction ZZ' and the second direction XX' are used to describe the orientation. Optionally, the first direction ZZ' and the second direction XX' are perpendicular to each other. When the locking member 100 is actually used, the first direction ZZ' can be along the thickness direction of the circuit board 300.

[0056] Please refer to Figure 1 and Figure 2 , the locking member 100 includes a body 110, a pressing portion 120 and an elastic positioning portion 130.

[0057] The body 110 is rotatably connected to the circuit board 300 about the axis of the first direction ZZ'. The locking member 100 has a locking position and an unlocking position, and can be switched between the locking position and the unlocking position by the rotation of the body 110.

[0058] The pressing portion 120 is connected to the body 110. When the locking member 100 is in the locking position, the pressing portion 120 presses the functional module 200 along the first direction ZZ'. When the locking member 100 is in the unlocking position, the pressing portion 120 releases the limit on the functional module 200 in the first direction ZZ'.

[0059] The elastic positioning portion 130 is connected to the body 110, and can cooperate with the first positioning structure 301 on the circuit board 300 under the action of elastic force to position the locking member 100 in the locking position. The elastic positioning portion 130 can be disengaged from the cooperation with the first positioning structure 301 under the action of an external force, so that the locking member 100 can be switched from the locking position to the unlocking position.

[0060] Please refer to Figure 5 and Figure 6 , when the locking member 100 is in the locking position, the pressing portion 120 presses the functional module 200 along the first direction ZZ' towards the direction close to the circuit board 300, so as to realize the limit on the functional module 200 along the first direction ZZ'. When the locking member 100 is in the locking position, the elastic positioning portion 130 can cooperate with the first positioning structure 301 on the circuit board 300 under the action of its own elastic force, so that the elastic positioning portion 130 is positioned, and then the body 110 connected to the elastic positioning portion 130 is positioned, that is, the locking member 100 is positioned in the locking position. At this time, the locking member 100 cannot rotate towards the unlocking position. Since the locking member 100 can be kept in the locking position, the locking member 100 can reliably limit the functional module 200 along the first direction ZZ', that is, realize the reliable fixation of the functional module 200.

[0061] By applying an external force to the elastic positioning portion 130 to overcome its elastic force, the elastic positioning portion 130 can be released from the first positioning structure 301, so that the body 110 can rotate relative to the circuit board 300 around the axis of the first direction ZZ', and the locking member 100 can be rotated from the locked position to the unlocked position by the rotation of the body 110. Since the pressing portion 120 releases the limit of the functional module 200 in the first direction ZZ' when the locking member 100 is in the unlocked position, that is, the pressing portion 120 rotates to a position staggered from the functional module 200, the functional module 200 can be released by the pressing portion 120 in the first direction ZZ', thereby facilitating the removal of the functional module 200 from the circuit board 300.

[0062] The locking member 100 is used to lock the functional module 200 to the circuit board 300. When the locking member 100 is in the locked position, the pressing portion 120 presses the functional module 200 along the first direction ZZ' to limit the functional module 200 along the first direction ZZ'. Since the elastic positioning portion 130 can cooperate with the first positioning structure 301 on the circuit board 300 under the action of its own elastic force, the locking member 100 is positioned in the locked position, so that the locking member 100 can reliably limit and fix the functional module 200 along the first direction ZZ'. By applying an external force to the elastic positioning portion 130 to overcome its elastic force, the elastic positioning portion 130 is released from the first positioning structure 301, so that the locking member 100 rotates from the locked position to the unlocked position, so that the pressing portion 120 releases the limit of the functional module 200 in the first direction ZZ', thereby facilitating the removal of the functional module 200 from the circuit board 300. It can be seen that the above-mentioned locking member 100 can realize the positioning or releasing of the locking member 100 in the locking position through the elastic deformation of the elastic positioning portion 130, and the switching between the locking position and the unlocking position can be realized by rotating the locking member 100 without the aid of other tools, thereby facilitating the installation and disassembly of the functional module 200.

[0063] Please combine Figure 2 , Figure 7 and Figure 8 In one embodiment, when the locking member 100 is in the unlocked position, the elastic positioning portion 130 can cooperate with the second positioning structure 302 on the circuit board 300 under the action of elastic force to position the locking member 100 in the unlocked position.

[0064] The elastic positioning portion 130 can be released from the second positioning structure 302 under the action of an external force, so that the locking member 100 can be switched from the unlocking position to the locking position.

[0065] When the functional module 200 needs to be disassembled, after the elastic positioning portion 130 is disengaged from the first positioning structure 301, the locking member 100 rotates from the locked position to the unlocked position through the rotation of the body 110. When the locking member 100 rotates to the unlocked position, the elastic positioning portion 130 can cooperate with the second positioning structure 302 on the circuit board 300 under the action of its own elastic force, so that the elastic positioning portion 130 is positioned, thereby facilitating the reminder to the operator that the locking member 100 is in the unlocked position.

[0066] Understandably, if the functional module 200 needs to be fixed, an external force can be applied to the elastic positioning portion 130 to overcome its elastic force, so that the elastic positioning portion 130 is disengaged from the second positioning structure 302, so that the locking member 100 can be switched from the unlocked position to the locked position through the rotation of the body 110, so that the pressing portion 120 presses the functional module 200.

[0067] Please refer to Figure 2 , in an embodiment, the pressing portion 120 has a pressing surface 121 for pressing the functional module 200. Along the direction in which the locking member 100 rotates from the locked position to the unlocked position, the pressing surface 121 gradually inclines towards the circuit board 300.

[0068] Since along the direction in which the locking member 100 rotates from the locked position to the unlocked position, the pressing surface 121 gradually inclines towards the circuit board 300. In Figure 5 and Figure 6 the shown orientation, that is, along the counterclockwise direction, the pressing surface 121 gradually inclines downwards. Combining Figure 8 , when the locking member 100 rotates in the clockwise direction (that is, from the unlocked position to the locked position), the pressing surface 121 can gradually press the functional module 200 tighter and tighter.

[0069] In this embodiment, along the direction in which the locking member 100 rotates from the locked position to the unlocked position, the pressing surface 121 gradually inclines towards the circuit board 300. As the locking member 100 rotates from the unlocked position to the locked position, the pressing surface 121 can gradually press the functional module 200 tighter and tighter, which is beneficial to the locking member 100 to lock the functional module 200 more reliably.

[0070] Please combine Figure 1 and Figure 2 , in an embodiment, the body 110 includes a rotating portion 111, a supporting portion 112 and a connecting shaft 113. Combining Figure 3The rotating portion 111 is rotatably disposed in the mounting hole 303 on the circuit board 300 around the axis of the first direction ZZ'. The supporting portion 112 is connected to one end of the rotating portion 111, and the supporting portion 112 is connected to the elastic positioning portion 130. The two ends of the connecting shaft 113 along the first direction ZZ' are respectively connected to the supporting portion 112 and the pressing portion 120.

[0071] The supporting portion 112 and the pressing portion 120 respectively protrude outward from the connecting shaft 113 in the radial direction of the connecting shaft 113 , so that a spacing space 120 a for clamping the functional module 200 is formed between the supporting portion 112 and the pressing portion 120 .

[0072] like Figure 6 As shown, the support portion 112 is used to support the functional module 200 in a direction away from the circuit board 300. When the locking member 100 is in the locking position, the pressing portion 120 and the support portion 112 clamp the functional module 200 together along the first direction ZZ', thereby fixing the functional module 200.

[0073] Since the support portion 112 is connected to the elastic positioning portion 130, when the elastic positioning portion 130 cooperates with the first positioning structure 301, the position of the support portion 112 is locked, so that the rotating portion 111 connected to the support portion 112 cannot rotate relative to the circuit board 300, thereby achieving the locking member 100 being positioned in the locked position. When the functional module 200 needs to be disassembled, the elastic positioning portion 130 is released from the first positioning structure 301, and the rotating portion 111 is rotated, such as Figure 8 As shown, the pressing portion 120 can be rotated to a position offset from the functional module 200 , that is, the functional module 200 is released.

[0074] In this embodiment, the support portion 112 and the pressing portion 120 clamp the functional module 200 together, so that the two sides of the functional module 200 along the first direction ZZ′ can be limited respectively, so that the functional module 200 can be fixed more reliably.

[0075] Specifically, the pressing surface 121 is a surface of the pressing portion 120 opposite to the supporting portion 112. Along the direction in which the locking member 100 rotates from the locking position to the unlocking position, the pressing surface 121 gradually tilts toward the direction close to the supporting portion 112.

[0076] Please refer to Figure 2 and Figure 8 In one embodiment, the functional module 200 is provided with a matching groove 201 that is rotatably matched with the connecting shaft 113, and the connecting shaft 113 can rotate in the matching groove 201. Through the matching of the matching groove 201 and the connecting shaft 113, it is convenient for the locking member 100 to stably rotate relative to the functional module 200 when switching between the unlocking position and the locking position.

[0077] Please refer toFigure 6 and Figure 8 In one embodiment, the locking member 100 further includes a stopping portion 140, and the stopping portion 140 is connected to a side of the pressing portion 120 close to the circuit board 300. When the locking member 100 is in the locking position, the stopping portion 140 abuts against the functional module 200 along the rotation direction of the locking member 100, so as to facilitate timely reminding the operator that the locking member 100 has rotated in place.

[0078] Specifically, the stopping portion 140 can be disposed between the pressing portion 120 and the supporting portion 112.

[0079] Please refer to Figure 2 and Figure 3 In one embodiment, the body 110 includes a rotating portion 111. The rotating portion 111 includes at least two elastic rotating arms 1111 arranged along the axis of the first direction ZZ' and spaced from each other, and a limiting portion 1112 correspondingly arranged with the elastic rotating arms 1111. The limiting portion 1112 is connected to an end of the elastic rotating arm 1111 far from the pressing portion 120. The limiting portion 1112 protrudes from the elastic rotating arm 1111 along a direction away from the axis of the first direction ZZ', so that the limiting portion 1112 can abut against the circuit board 300 along the first direction ZZ'. The at least two elastic rotating arms 1111 can approach each other under an external force, so that the limiting portion 1112 can pass through the mounting hole 303 on the circuit board 300.

[0080] When the locking member 100 is installed on the circuit board 300, the rotating portion 111 passes through the mounting hole 303 on the circuit board 300, so that the locking member 100 can be rotated in the mounting hole 303 to realize the switching between the locking position and the unlocking position of the locking member 100. Since the limiting portion 1112 protrudes from the limiting portion 1112 along a direction away from the axis of the first direction ZZ', that is, the limiting portion 1112 protrudes radially outward from the elastic rotating arm 1111 along the mounting hole 303, the limiting portion 1112 can be mutually limited with the circuit board 300 along the first direction ZZ', and further, the limiting portion 1112 can be prevented from moving out of the mounting hole 303 along the first direction ZZ' towards the direction close to the pressing portion 120, that is, the locking member 100 is prevented from detaching from the mounting hole 303.

[0081] By applying an external force to the at least two elastic rotating arms 1111 to overcome the elastic force, the at least two elastic rotating arms 1111 can approach each other, so that the respective limiting portions 1112 can approach each other, and further, the respective limiting portions 1112 can pass through the mounting hole 303 on the circuit board 300. In this way, it is convenient to realize the installation and disassembly of the limiting portion 1112. When the limiting portion 1112 moves out of the mounting hole 303 towards the direction close to the pressing portion 120, that is, the locking member 100 as a whole detaches from the circuit board 300. At this time, the functional module 200 is not limited by the locking member 100 in any direction, so that the functional module 200 can be disassembled more conveniently.

[0082] In Figure 2 the illustrated embodiment, the number of the elastic swing arms 1111 is two. In other embodiments, the number of the elastic swing arms 1111 may be three or more.

[0083] As Figure 3 and Figure 4 shown, in one embodiment, a adapter base 310 is provided on the circuit board 300. The adapter base 310 has a slot. One end of the functional module 200 away from the locking member 100 along the second direction XX' is inserted into the slot of the adapter base 310 along the second direction XX', so that one end of the functional module 200 away from the locking member 100 along the second direction XX' can be indirectly connected to the circuit board 300 through the adapter base 310.

[0084] In this embodiment, when the locking member 100 rotates to the unlocking position, the pressing portion 120 releases the limit on the functional module 200 along the first direction ZZ'. At this time, one end of the functional module 200 close to the locking member 100 can be lifted along the first direction ZZ' in a direction away from the circuit board 300 (upward in Figure 7 ), so that one end of the functional module 200 close to the locking member 100 is tilted upward, and thus one end of the functional module 200 close to the adapter base 310 can be pulled out from the adapter base 310.

[0085] It can be understood that the functional module 200 has a certain movement space in the slot of the adapter base 310. In this way, when one end of the functional module 200 close to the locking member 100 is lifted along the first direction ZZ' in a direction away from the circuit board 300, the slot of the adapter base 310 can allow one end of the functional module 200 located in the slot to move.

[0086] Please refer to Figure 2 , in one embodiment, grooves 1111a are respectively provided on one side of each elastic swing arm 1111 close to the axis of the first direction ZZ'.

[0087] By providing the grooves 1111a, the elastic swing arms 1111 can be more easily elastically deformed, so that the elastic swing arms 1111 can be closer to each other, and thus it is convenient for the limiting portion 1112 to pass through the mounting hole 303.

[0088] Please refer to Figure 2 , in one embodiment, the rotating portion 111 further includes a protruding portion 1111b corresponding to the elastic swing arm 1111. The protruding portion 1111b is provided on the surface of the corresponding elastic swing arm 1111 away from the axis of the first direction ZZ' and abuts against the hole wall of the mounting hole 303.

[0089] The protruding portion 1111b is provided on the surface of the elastic rotating arm 1111 on the side away from the axis in the first direction ZZ', and abuts against the hole wall of the mounting hole 303. In this way, without increasing the radial dimension of the elastic rotating arm 1111, the rotating portion 111 can be more easily abutted against the hole wall of the mounting hole 303, so that the sway of the rotating portion 111 in the mounting hole 303 can be sufficiently reduced, and then the rotating portion 111 can be kept stable in the mounting hole 303.

[0090] In one embodiment, the supporting portion 112 abuts against the circuit board 300 in the first direction ZZ', so that the supporting portion 112 and the circuit board 300 are limited to each other in the first direction ZZ', and the position of the locking member 100 in the first direction ZZ' can be kept stable.

[0091] Please refer to Figure 1 , in one embodiment, one end of the elastic positioning portion 130 is connected to the body 110, and the other end of the elastic positioning portion 130 has a clamping protrusion 131. The first positioning structure 301 is a first clamping groove. The elastic positioning portion can make the clamping protrusion 131 cooperate with the first clamping groove under the action of an elastic force.

[0092] By elastically deforming the elastic positioning portion 130, the clamping protrusion 131 is made to cooperate with the first clamping groove, so that it is convenient to position the locking member 100 at the locking position through the elastic positioning portion 130.

[0093] In one embodiment, the second positioning structure 302 is a second clamping groove. By elastically deforming the elastic positioning portion 130, the clamping protrusion 131 is made to cooperate with the second clamping groove, so that it is convenient to position the locking member 100 at the unlocking position through the elastic positioning portion 130.

[0094] Please refer to Figure 1 , in one embodiment, an avoidance groove 110a is provided on the body 110, and the elastic positioning portion 130 is located in the avoidance groove 110a. The avoidance groove 110a provides a moving space for the deformation of the elastic positioning portion 130.

[0095] Specifically, the avoidance groove 110a can be provided at one end of the supporting portion 112 close to the rotating portion 111.

[0096] Please refer to Figure 2 , in one embodiment, an annular groove 112a around the axis in the first direction ZZ' is provided on the supporting portion 112.

[0097] The number of the annular grooves 112a can be one, or a plurality of annular grooves 112a are arranged at intervals in the first direction ZZ'. It can be understood that two adjacent annular units 1121 are formed on both sides of each annular groove 112a in the first direction ZZ'. In Figure 2In the illustrated embodiment, the number of the annular grooves 112a is two, so that the supporting part 112 includes three annular units 1121 in total.

[0098] When the size of the supporting part 112 is relatively large, it is not convenient to be formed by a mold. In this embodiment, by providing the annular grooves 112a on the supporting part 112, it is convenient to process and form the supporting part 112 by a mold.

[0099] Furthermore, the avoiding groove 110a can be provided on the annular unit 1121 adjacent to the rotating part 111.

[0100] Please refer to Figure 2 , in an embodiment, the outer diameter of the annular unit 1121 adjacent to the rotating part 111 is larger than the outer diameters of the other annular units 1121.

[0101] Specifically, the annular unit 1121 adjacent to the rotating part 111 is used to abut against the circuit board 300 to limit each other with the circuit board 300 along the first direction ZZ'. By making the annular unit 1121 adjacent to the rotating part 111 larger, a more reliable and stable limit can be formed between this annular unit 1121 and the circuit board 300, which is beneficial to keeping the locking part 100 stable.

[0102] Please refer to Figure 8 , in an embodiment, the extending direction of the pressing part 120 is along a circumferential direction around the axis of the first direction ZZ', and the extending angle of the pressing part 120 is greater than or equal to 90° and less than or equal to 180°.

[0103] In this way, the pressing part 120 can have a longer extending length, so as to provide a larger pressing area for the functional module 200 as much as possible, which is beneficial to reliably pressing the functional module 200.

[0104] Specifically, the pressing part 120 is disposed around the connecting shaft 113 along the circumferential direction of the connecting shaft 113, and the surrounding angle is less than or equal to 180°.

[0105] In an embodiment, the stopping part 140 is disposed at the middle of the pressing part 120 along its extending direction, which is beneficial to stably supporting the pressing part 120 by the stopping part 140.

[0106] Please refer to Figure 8 , in an embodiment, the supporting surface of the supporting part 112 for supporting the functional module 200 surrounds the connecting shaft 113. In this way, when the locking part 100 rotates relative to the circuit board 300 around the axis of the first direction ZZ' to any position, the supporting part 112 can support the functional module 200, which is convenient for the functional module 200 to keep the position stable and convenient for operating during the installation and disassembly of the functional module 200.

[0107] Please refer toFigure 1 In one embodiment, the locking member 100 further includes a holding portion 150. The holding portion 150 is connected to the pressing portion 120 and protrudes from the pressing portion 120 in a direction away from the circuit board 300.

[0108] Through the holding portion 150, an operator can perform a rotation operation on the holding portion 150, thereby driving the entire locking member 100 to rotate, so as to realize the switching between the locking position and the unlocking position, which is convenient for operation.

[0109] One embodiment of the present application further provides an electronic device, including a circuit board 300, a functional module 200, and the locking member 100 according to any one of the above embodiments. The functional module 200 is locked to the circuit board 300 through the above-mentioned locking member 100.

[0110] In one embodiment, the functional module 200 is a solid-state drive.

[0111] In other embodiments, the functional module 200 may also be a module for implementing other functions, such as a wireless transmission module.

[0112] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0113] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
