[0002] In related technologies, an M.2 solid-state drive (SSD) has a connector segment at one end along its length and a semi-circular notch at the other end. The connector segment plugs into a dedicated M.2 connector on the motherboard for data communication, while the other end is fixed to the motherboard with screws.

[0003] However, installing and removing M.2 SSDs requires specialized tools, making the process inconvenient. Furthermore, the screws used for mounting M.2 SSDs are small and easily lost after disassembly. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this utility model is to provide an M.2 solid-state drive (SSD) limiting structure. By allowing the limiting part to move relative to the fixing base along the side closer to or further away from the M.2 connector, the separation between the M.2 SSD and the M.2 connector is restricted or permitted, thereby enabling the installation and removal of the M.2 SSD on the motherboard. This improves the convenience of installation and removal and avoids the inconvenience caused by easily lost screws after disassembly.

[0005] This utility model also proposes a motherboard.

[0006] A first aspect of this utility model provides an M.2 solid-state drive (SSD) limiting structure, comprising a fixing base, a limiting part, and a reset member. The fixing base is used for fixed mounting on a motherboard body; the limiting part is movably mounted on the fixing base and has a locking position near the M.2 connector on the motherboard body and an unlocking position away from the M.2 connector on the motherboard body. In the locking position, the limiting part engages with a semi-circular notch of the M.2 SSD to fix the M.2 SSD between the M.2 connector on the motherboard and the limiting part; in the unlocking position, the limiting part separates from the semi-circular notch of the M.2 SSD to allow the M.2 SSD to detach from the motherboard body; the reset member is used to drive the limiting part back from the unlocking position to the locking position.

[0007] In some embodiments, the limiting portion has a guide hole; the fixing base includes a motherboard mounting portion and a guide post; the motherboard mounting portion is used to be fixedly mounted on the motherboard body, and the guide post protrudes from the motherboard mounting portion; wherein, the diameter of the guide hole is larger than the diameter of the guide post so that when the limiting portion moves in the vertical direction, it can move along the radial direction of the guide post and toward the side away from the M.2 connector.

[0008] In some embodiments, the guide hole includes a large-diameter hole and a small-diameter hole arranged sequentially along the axial direction of the guide post; a stop member is provided at one end of the guide post away from the motherboard mounting portion, and the radial dimension of the stop member is greater than the diameter of the small-diameter hole and smaller than the diameter of the large-diameter hole.

[0009] In some embodiments, the guide hole further includes a tapered hole disposed between the large-diameter hole and the small-diameter hole; in the locked position, the circumferential surface of the stop member abuts against the wall of the tapered hole.

[0010] In some embodiments, the limiting portion includes a sleeve, a first rod ring, and a second rod ring; the sleeve extends axially through at least one end to form the guide hole; the first rod ring and the second rod ring protrude radially from the outer peripheral surface of the sleeve and are spaced apart axially along the sleeve to form a slot for engaging an M.2 solid-state drive; wherein, in the locked position, the radial protrusion distance of the first rod ring and the second rod ring is configured to be greater than the radius of the semi-circular notch of the M.2 solid-state drive.

[0011] In some embodiments, the second rod ring is located between the first rod ring and the main board mounting portion; the first rod ring has a guide surface on the side opposite to the second rod ring, and the guide surface is inclined axially and radially outward along the sleeve.

[0012] In some embodiments, the guide surface is constructed as an arc surface or an inclined surface.

[0013] In some embodiments, the reset element is constructed as a spring, which is sleeved outside the guide post and its two ends abut against the motherboard mounting portion and the limiting portion, respectively; wherein, in the locked position, the spring is in a compressed state.

[0014] In some embodiments, the limiting portion and the motherboard mounting portion are respectively provided with a first receiving groove and a second receiving groove; the openings of the first receiving groove and the second receiving groove are arranged opposite to each other so that a portion of the spring is received in the first receiving groove and the second receiving groove.

[0015] The second aspect of this utility model provides a motherboard, which includes a motherboard body, an M.2 connector disposed on the motherboard body, and an M.2 solid-state drive limiting structure as described in the first aspect of this utility model, wherein the fixing base is detachably mounted on the motherboard body.

[0016] Based on the technical solution, it can be seen that the embodiments provided by this utility model have the following advantages: (1) By driving the limiting part, the limiting part overcomes the driving force of the reset part and moves from the locked position to the unlocked position. Then, the limiting part is aligned with the semi-circular notch of the M.2 solid-state drive or the limiting part is separated from the semi-circular notch of the M.2 solid-state drive to realize the installation and removal of the M.2 solid-state drive. Therefore, this embodiment realizes the tool-free installation and removal of the M.2 solid-state drive on the motherboard, which completely solves the technical problem that the screws of the M.2 solid-state drive installation screws are small and easy to lose after disassembly, and improves the convenience and reliability of installation and removal.

[0017] (2) The drive limit part of the reset part moves from the unlocked position to the locked position without manual reset, which can further improve the convenience of disassembly and assembly;

[0037] The following is for reference. Figures 1-12 The present invention describes an M.2 solid-state drive limiting structure 100 and a motherboard 1000 according to an embodiment of the present invention.

[0038] Example 1

[0039] like Figure 1 As shown, the first aspect of this utility model provides an M.2 solid-state drive limiting structure 100.

[0040] like Figure 2 As shown, the M.2 solid-state drive limiting structure 100 includes a fixing base 1, a limiting part 2, and a reset member 3. The fixing base 1 can be fixedly installed on the motherboard body 200.

[0041] See Figure 3 and Figure 4 The limiting part 2 is movably mounted on the fixing base 1 and has a locking position close to the M.2 connector 300 on the motherboard body 200 and an unlocking position away from the M.2 connector 300 on the motherboard body 200: In the locking position, the limiting part 2 engages with the semi-circular notch 402 of the M.2 solid-state drive 400 to fix the M.2 solid-state drive 400 between the M.2 connector 300 and the limiting part 2 on the motherboard 1000; In the unlocking position, the limiting part 2 separates from the semi-circular notch 402 of the M.2 solid-state drive 400 to allow the M.2 solid-state drive 400 to detach from the motherboard body 200; the reset member 3 can drive the limiting part 2 to reset from the unlocking position to the locking position.

[0042] like Figure 1 As shown, in a specific application scenario, the motherboard body 200 is equipped with an M.2 connector 300 and an M.2 solid-state drive limiting structure 100. For example... Figure 1 and Figure 3As shown, during installation, the M.2 solid-state drive 400's insertion end 401 in the longitudinal direction is inserted into the M.2 connector 300 on the motherboard body 200, thereby enabling data and power transmission between the M.2 connector 300 and the M.2 solid-state drive 400. Then, the driving limiting part 2 is moved from the locked position to the unlocked position, overcoming the reset force of the reset member 3. That is, the driving limiting part 2 moves relative to the fixing base 1 along the side away from the M.2 connector 300 on the motherboard body 200, and then the semi-circular notch 402 of the M.2 solid-state drive 400 is approximately aligned with the limiting part 2; as... Figures 4-6 As shown, finally, the driving force is removed, so that the limiting part 2 moves automatically from the unlocked position to the locked position under the drive of the reset part 3. The limiting part 2 can engage with the semi-circular notch 402 of the M.2 solid-state drive 400 so that the M.2 solid-state drive 400 is fixed between the M.2 connector 300 and the limiting part 2 on the motherboard body 200.

[0043] like Figure 3 As shown, during disassembly, the drive limiting part 2 overcomes the reset force of the reset member 3, causing the limiting part 2 to move from the locked position to the unlocked position. That is, the limiting part 2 moves relative to the fixing base 1 along the side away from the M.2 connector 300 on the motherboard body 200, and the semi-circular notch 402 of the M.2 solid-state drive 400 separates from the limiting part 2; as Figure 2 As shown, then directly unplug the M.2 solid-state drive 400 from the M.2 connector 300.

[0044] As can be seen from the technical solution, the embodiments provided by this utility model have the following advantages:

[0045] (1) In this embodiment, the limiting part 2 is driven to overcome the driving force of the reset part 3 and move from the locked position to the unlocked position. Then the limiting part 2 is aligned with the semi-circular notch 402 of the M.2 solid-state drive 400 or the limiting part 2 is separated from the semi-circular notch 402 of the M.2 solid-state drive 400 to realize the installation and removal of the M.2 solid-state drive 400. Therefore, this embodiment realizes the tool-free installation and removal of the M.2 solid-state drive 400 on the motherboard 1000, which completely solves the technical problem that the screws of the M.2 solid-state drive 400 are easily lost after disassembly due to their small size, and improves the convenience and reliability of installation and removal.

[0046] (2) The drive limit part 2 of the reset part moves from the unlocked position to the locked position without manual reset, which can further improve the convenience of disassembly and assembly;

[0047] (3) By using the M.2 solid-state drive limiting structure 100 to snap the semi-circular notch 402 of the M.2 solid-state drive 400, the stability and reliability of the connection between the M.2 solid-state drive 400 and the M.2 connector 300 on the motherboard body 200 can be improved.

[0048] Example 2

[0049] Combination Figure 2 and Figure 7 As shown, the limiting part 2 further has a guide hole 211.

[0050] The mounting base 1 includes a motherboard mounting part 11 and a guide post 12; the motherboard mounting part 11 is used to fix the motherboard 1000, and the guide post 12 protrudes from the motherboard mounting part 11; wherein, the diameter of the guide hole 211 is larger than the diameter of the guide post 12 so that the limiting part 2 can move along the radial direction of the guide post 12 and away from the M.2 connector 300 when the guide post 11 moves axially, and the movement relationship between the two is detailed in the following description.

[0051] like Figure 1 and Figure 2 As shown, the motherboard mounting part 11 is mounted on the motherboard body 200, and the guide post 12 protrudes from the motherboard mounting part 11. Therefore, the guide post 12 also protrudes from the motherboard body 200 and is spaced apart from the M.2 connector 300.

[0052] Combination Figure 3 and Figure 7 As shown, specifically in this embodiment, the movement of the limiting part 2 is achieved through the following combined movement: the guide hole 211 engages with the guide post 12, allowing the limiting part 2 to move along the extension direction (axial direction of the guide post 12). Simultaneously, since the diameter of the guide hole 211 is larger than the diameter of the guide post 12, i.e., there is a clearance fit between the guide hole 211 and the guide post 12, the limiting part 2 can move radially relative to the guide post 12. Specifically, the limiting part 2 can move radially away from the M.2 connector 300 relative to the guide post 12, and the limiting part 2 can also move radially closer to the M.2 connector 300 relative to the guide post 12.

[0053] During installation, the M.2 solid-state drive 400 is inserted into the M.2 connector 300 on the motherboard body 200 at its longitudinal insertion end 401. Then, a driving force is applied to the other end of the M.2 solid-state drive 400 in the longitudinal direction, perpendicular to the motherboard body 200 (pressing down the other end of the M.2 solid-state drive 400 in the longitudinal direction), causing the limiting part 2 to tilt (the limiting part 2 moves along the axial direction of the guide post 12 and close to the motherboard body 200, while simultaneously moving radially away from the M.2 connector 300 relative to the guide post 12); after the pressing action is released, the reset member 3 drives the limiting part 2 back to the locked position (the limiting part 2 moves along the axial direction of the guide post 12 and away from the motherboard body 200, while simultaneously moving radially towards the M.2 connector 300 relative to the guide post 12).

[0054] In a specific example, the axis of the guide post 12 is perpendicular to the plane where the main body 200 is located.

[0055] In summary, in this embodiment, after the M.2 solid-state drive 400 is plugged into the M.2 connector 300, the other end of the M.2 solid-state drive 400 is pressed down to cause the limiting part 2 to tilt away from the M.2 connector 300 relative to the motherboard mounting part 11 when it moves in the vertical direction, until it reaches the unlock position; finally, the pressing operation is canceled, and the reset member 3 drives the limiting part 2 to move along the axial direction of the guide post 12 and away from the motherboard body 200. At the same time, the limiting part 2 moves in the radial direction relative to the guide post 12 towards the M.2 connector 300 to return to the locked position.

[0056] In this embodiment, the limiting part 2 and the semi-circular notch 402 of the M.2 solid-state drive 400 descend synchronously, which increases the buffering effect during installation and reduces the impact on the M.2 solid-state drive 400; at the same time, the guide post 12 restricts the distance of the limiting part 2, reduces the risk of dislodgement, and improves the convenience of installation.

[0057] Example 3

[0058] This embodiment is basically the same as Embodiment 2, except for the specific structure of the guide post 12 and the guide hole 211.

[0059] like Figure 7 and Figure 8 As shown, the guide hole 211 further includes a large-diameter hole 2111 and a small-diameter hole 2112 arranged sequentially along the axial direction of the guide post 12; a stop member 13 is provided at one end of the guide post 12 away from the main board mounting part 11, and the radial dimension of the stop member 13 is larger than the diameter of the small-diameter hole 2112 and smaller than the diameter of the large-diameter hole 2111.

[0060] The large-diameter hole 2111 and the small-diameter hole 2112 are connected and both are larger than the diameter of the guide post 12.

[0061] Therefore, by setting the stop 13, the limit part 2 can be prevented from accidentally dislodging from the guide hole 211.

[0062] like Figure 7 and Figure 8As shown, the guide hole 211 further includes a tapered hole 2113, which is located between the large-diameter hole 2111 and the small-diameter hole 2112. In the locked position, the circumferential surface of the stop member 13 abuts against the wall of the tapered hole 2113. Combined with the reset action of the reset member 3, the stop member 13 moves towards the side of the small-diameter hole 2112 along a direction perpendicular to the main board body 200, and when passing through the tapered hole 2113, the circumferential surface of the stop member 13 gradually clamps the wall of the tapered hole 2113 to eliminate radial clearance and reduce radial movement of the limiting part 2 in the locked position.

[0063] Specifically, the large-diameter hole 2111, the tapered hole 2113, and the small-diameter hole 2112 are coaxial and connected. The maximum diameter of the tapered hole 2113 is equal to the diameter of the large-diameter hole 2111, and the minimum diameter of the tapered hole 2113 is equal to the diameter of the small-diameter hole 2112.

[0064] like Figure 7 and Figure 8 As shown, the stop member 13 is further constructed as a frustum coaxially arranged with the guide post 12, and the circumferential surface of the frustum is a conical surface, the radius of which gradually decreases along one end of the guide post 12.

[0065] like Figure 9 As shown, the guide post 12 is further detachably mounted on the motherboard mounting portion 11. Specifically, when assembling the M.2 solid-state drive limiting structure 100 with the motherboard body 200, the motherboard mounting portion 11 is first fixed to the motherboard body 200. Then, the large-diameter hole 2111 of the limiting portion 2 passes through the other end of the guide post 12 without the stop member 13, so that the guide post 12 passes through the guide hole 211 of the limiting portion 2. Finally, the guide post 12 is assembled on the motherboard mounting portion 11, which helps to improve the convenience of assembly between the M.2 solid-state drive limiting structure 100 and the motherboard body 200.

[0066] Example 4

[0067] This embodiment is basically the same as Embodiment 2, except for the specific structure of the limiting part 2.

[0068] like Figure 7 , Figure 8 and Figure 10 As shown, the limiting part 2 further includes a sleeve 21, a first rod ring 22, and a second rod ring 23; the sleeve 21 extends axially through at least one end to form a guide hole 211; the first rod ring 22 and the second rod ring 23 protrude radially from the outer peripheral surface of the sleeve 21 and are spaced apart axially along the sleeve 21 to form a slot 24 for engaging the M.2 solid-state drive 400; wherein, in the locked position, the radial protrusion distance of the first rod ring 22 and the second rod ring 23 is configured to be greater than the radius of the semi-circular notch 402 of the M.2 solid-state drive 400.

[0069] Specifically, the sleeve 21 is coaxially arranged with the guide post 12. By setting two axially spaced limiting structures to form a slot 24, the part of the M.2 solid-state drive 400 with the semi-circular notch 402 is embedded in the slot 24. The first rod ring 22 and the second rod ring 23 provide axial constraints on the M.2 solid-state drive 400 from the upper and lower directions, respectively, which helps to reduce the probability of the hard drive tilting upward or loosening downward in a vibration or movement environment, and provides a more stable and reliable locking effect than a single limiting point.

[0070] like Figure 11 As shown, the second ring 23 is further located between the first ring 22 and the motherboard mounting part 11; the first ring 22 has a guide surface 221 on the side opposite to the second ring 23, and the guide surface 221 is inclined axially and radially outward along the sleeve 21. When installing the M.2 solid-state drive 400, pressing down on the M.2 solid-state drive 400 will cause the edge of the M.2 solid-state drive 400 to first contact the guide surface 221. Due to the action of the guide surface 221, the vertically downward force applied by the hard drive is decomposed into a vertical component and a horizontal component. This horizontal component directly drives the entire limiting part 2 to overcome the force of the reset member 3 and move radially away from the M.2 connector 300. That is, during installation, there is no need to drive the limiting part 2. The limiting part 2 can enter the unlocked position to make way for the hard drive. Therefore, no additional manual unlocking operation is required during installation. The installation of the M.2 solid-state drive 400 can be achieved by simply pressing down.

[0071] Furthermore, the guide surface 221 is constructed as an arc surface or an inclined surface.

[0072] When the guide surface 221 is constructed as a curved surface, it provides a smoother force transition area, increasing the contact area between the edge of the M.2 solid-state drive 400 and the limiting part 2, greatly reducing impact and frictional resistance. This makes the downward pressing action less strenuous and the feel smoother, while effectively reducing scratches or wear that may occur to the edge of the M.2 solid-state drive 400 and the limiting part 2 structure due to hard impacts, thus protecting the product surface.

[0073] When the guide surface 221 is constructed as a plane, the production cost of the M.2 solid-state drive limiting structure 100 is lower.

[0074] Example 5

[0075] This embodiment is basically the same as embodiment two, except for the specific structure of the reset component 3.

[0076] like Figure 9As shown, the reset element 3 is further constructed as a spring, which is sleeved outside the guide post 12, with its two ends abutting against the motherboard mounting portion 11 and the limiting portion 2, respectively. In the locked position, the spring is in a compressed state. Therefore, regardless of whether it is in the unlocked or locked position, the spring continuously applies an elastic reset force to the limiting portion 2 in a direction away from the motherboard mounting portion 11. This force is the driving force that automatically and reliably returns the limiting portion 2 from the unlocked position to the locked position, thus improving the reliability of automatic reset. Sleeving the spring outside the guide post 12 also improves the compactness of the structure.

[0077] like Figure 7 and Figure 12 As shown, furthermore, the limiting part 2 and the main board mounting part 11 are respectively provided with a first receiving groove 111 and a second receiving groove 231; the openings of the first receiving groove 111 and the second receiving groove 231 are arranged opposite to each other so that part of the spring is received in the first receiving groove 111 and the second receiving groove 231. Thus, the first receiving groove 111 and the second receiving groove 231 provide radial restraint for the ends of the spring, which can effectively prevent the spring from radially slipping, laterally bending, or accidentally dislodging from the guide post 12 during compression and reset. Especially when the limiting part 2 is radially tilted relative to the guide post 12, the receiving groove helps to keep both ends of the spring in the correct position, improving the reliability of the reset force.

[0078] The openings of the first receiving groove 111 and the second receiving groove 231 being opposite to each other means that the first receiving groove 111 is formed on the surface of the limiting part 2 facing the motherboard mounting part 11, with its opening facing the motherboard mounting part 11. The second receiving groove 231 is formed on the surface of the motherboard mounting part 11 facing the limiting part 2, with its opening facing the limiting part 2.

[0079] As can be seen from the above embodiment four, the first receiving groove 111 is formed at the end of the sleeve 21 near the motherboard mounting part 11 or on the surface of the second rod ring 23 away from the first limiting structure.

[0080] Specifically, the first receiving groove 111 is a first annular groove formed on the limiting part 2, and the first annular groove has a coaxial first annular opening; the second receiving groove 231 is a second annular groove formed on the motherboard mounting part 11, and the second annular groove has a coaxial second annular opening. The first annular groove, the second annular groove and the limiting post are coaxial.

[0081] Example 6

[0082] like Figures 1-6As shown, the second aspect of this utility model provides a motherboard 1000, which includes a motherboard body 200, an M.2 connector 300 disposed on the motherboard body 200, and an M.2 solid-state drive limiting structure 100 of the first aspect of this utility model. The fixing base 1 is detachably installed on the motherboard body 200.

[0083] As can be seen from the technical solution, the embodiments provided by this utility model have the following advantages:

[0084] (1) By setting the above-mentioned M.2 solid-state drive limiting structure 100, the limiting part 2 can be driven to overcome the driving force of the reset member 3 and move from the locked position to the unlocked position. Then, the limiting part 2 is aligned with the semi-circular notch 402 of the M.2 solid-state drive 400 or the limiting part 2 is removed from the semi-circular notch 402 of the M.2 solid-state drive 400, so as to realize the installation and removal of the M.2 solid-state drive 400. Therefore, this embodiment realizes the tool-free installation and removal of the M.2 solid-state drive 400 on the motherboard 1000, and completely solves the problem of tool-free installation and removal of the M.2 solid-state drive 400. The small size of the mounting screws for the M.2 SSD 400 improves the convenience and reliability of disassembly and assembly, addressing the technical issue of easy loss after disassembly due to their small size. Furthermore, the drive limit part 2 of the reset part moves from the unlocked position to the locked position without manual reset, further enhancing the convenience of disassembly and assembly. The semi-circular notch 402 of the M.2 SSD 400, which is engaged by the M.2 SSD limiting structure 100, improves the stability and reliability of the connection between the M.2 SSD 400 and the M.2 connector 300 on the motherboard body 200.

[0085] (2) The M.2 fixed hard drive limiting structure can be detachably installed on the motherboard body 200 via the fixing bracket 1. It can be used as an independent, pre-assembled functional module, which simplifies the overall assembly process of the motherboard 1000 and improves production efficiency. If the limiting structure is damaged by accident, only the module can be replaced without replacing the entire motherboard 1000 or performing complicated repair operations.

[0086] The following is combined Figures 1-12 Describe a specific example.

[0087] The motherboard 1000 includes a motherboard body 200, an M.2 connector 300 disposed on the motherboard body 200, an M.2 solid-state drive limiting structure 100 disposed on the motherboard body 200, and an M.2 solid-state drive 400.

[0088] The M.2 solid-state drive limiting structure 100 includes a fixing base 1, a limiting part 2, and a reset part 3.

[0089] The mounting base 1 includes a motherboard mounting part 11 and a guide post 12. The motherboard mounting part 11 has an M3 stud for screwing the motherboard body 200 and a screw hole for screwing the guide post 12. The guide post 12 is provided with a stop member 13 at one end away from the motherboard body 200. The stop member 13 is constructed as a frustum coaxially arranged with the guide post 12, and the circumferential surface of the frustum is a conical surface.

[0090] The limiting part 2 includes a sleeve 21, with both ends of the sleeve 21 extending through to form a guide hole 211. The guide hole 211 includes a large-diameter hole 2111, a tapered hole 2113, and a small-diameter hole 2112 arranged sequentially along the axial direction of the sleeve 21. The small-diameter hole 2112 is located between the main board mounting part 11 and the large-diameter hole 2111. The large-diameter hole 2111, the tapered hole 2113, and the small-diameter hole 2112 are coaxial and connected. The maximum diameter of the tapered hole 2113 is equal to the diameter of the large-diameter hole 2111, and the minimum diameter of the tapered hole 2113 is equal to the diameter of the small-diameter hole 2112.

[0091] The radial dimension of the stop 13 is greater than the diameter of the small diameter hole 2112 and smaller than the diameter of the large diameter hole 2111.

[0092] The reset component 3 is constructed as a spring connected between the fixed base 1 and the limiting part 2.

[0093] Therefore, the limiting part 2 can be rocked on the fixed base 1, and after the limiting part 2 is rocked, it can be returned to the horizontal state under the action of the spring.

[0094] The limiting part 2 includes a first rod ring 22 and a second rod ring 23; the sleeve 21 extends through both ends along the axial direction to form a guide hole 211; the first rod ring 22 and the second rod ring 23 are radially protruding from the outer peripheral surface of the sleeve 21 and spaced apart along the axial direction of the sleeve 21 to form a slot 24 for engaging the M.2 solid-state drive 400; wherein, in the locked position, the radial protrusion distance of the first rod ring 22 and the second rod ring 23 is configured to be greater than the radius of the semi-circular notch 402 of the M.2 solid-state drive 400.

[0095] The guide post 12 is detachably mounted on the motherboard mounting section 11. When assembling the M.2 solid-state drive limiting structure 100 with the motherboard body 200, first, the motherboard mounting section 11 is fixed to the motherboard body 200. Then, the large-diameter hole 2111 of the limiting section 2 passes through the other end of the guide post 12 without the stop member 13, so that the guide post 12 passes through the guide hole 211 of the limiting section 2. Finally, the guide post 12 is assembled onto the motherboard mounting section 11. The axis of the guide post 12 is perpendicular to the plane of the motherboard body 200, thereby allowing the limiting section 2 to move in a direction perpendicular to the plane of the motherboard body 200.

[0096] The second rod ring 23 is located between the first rod ring 22 and the main board mounting part 11; the first rod ring 22 has a guide surface 221 on the side away from the second rod ring 23. The guide surface 221 is inclined along the axial direction and along the radial outer side of the sleeve 21, and the guide surface 221 is an arc-shaped surface.

[0097] The surface of the second spring ring 23 facing away from the first limiting structure has a first receiving groove 111; the surface of the M3 stud facing the limiting part has a second receiving groove 231. Part of the spring is accommodated in the first receiving groove 111 and the second receiving groove 231.

[0098] When the M.2 solid-state drive 400 is not installed, the limiting structure is in its natural state. When the M.2 solid-state drive 400 is inserted into the M.2 connector 300, the semi-circular notch 402 of the M.2 solid-state drive 400 contacts the guide surface 221, and the limiting part 2 tilts along the side away from the M.2 connector 300, so that the semi-circular notch 402 of the M.2 solid-state drive 400 is engaged in the slot 24. When the M.2 solid-state drive 400 is laid flat, the limiting part 2 returns to its original position under the action of the spring, and the limiting part 2 locks the M.2 solid-state drive 400, preventing it from falling out.
