[0002] Network and IT products often feature modular designs, and most modules need to support pluggable functionality for easy user maintenance. Examples include pluggable modules such as fan modules, power supply modules, and single-board modules. As products become more complex and multifunctional, the operational space available for these pluggable modules becomes increasingly limited. Currently, most pluggable modules use push-button or lever-type unlocking mechanisms, requiring relatively complex structural movements to unlock. These complex structures are more prone to failure.

[0006] In some embodiments, the bracket assembly includes a bracket and a protective net. The bracket and the protective net are two independent structures, or the bracket and the protective net are an integrally formed structure.

[0007] In some embodiments, when the bracket and the protective net are two independent structures, the bracket has an annular protruding portion and a mounting plate with a central through hole. The annular protruding portion is fixed in the middle of the mounting plate, and the edge of the mounting plate protrudes from the outer side surface of the annular protruding portion. The inner diameter of the annular protruding portion is adapted to the central through hole; the edge of the mounting plate is provided with a first type of groove matching the number of the elastic pieces and a second type of groove matching the number of the elastic clamping claws; the protective net is adapted to the outer edge of the mounting plate and has at least one elastic piece and at least one elastic clamping claw.

[0008] In some embodiments, the protective net is an integrally formed structure.

[0009] In some embodiments, a "day" - shaped panel is provided on one side of the rotating portion close to the handheld portion. The outer edge of the "day" - shaped panel matches the circumferential edge of the rotating portion; the handheld portion is in a "T" shape and is arranged on the horizontal plate of the "day" - shaped panel; the horizontal portion of the "T" - shaped handheld portion is parallel to the horizontal plate.

[0010] The second aspect of the present application provides a plug - and - play module, which is plug - and - play installed in a box - shaped housing and includes the above - mentioned locking mechanism, a plug - and - play module body, a front panel and a fastener. The front panel includes a front end face and a side end face. The front end face and the side end face form a receiving cavity. The front end face has a panel through hole. The rotating portion in the locking mechanism is placed in the receiving cavity, and the handheld portion passes through the panel through hole and is exposed outside; the fastener fixes the plug - and - play module body, the locking mechanism and the front panel into one body; when the handheld portion exposed outside is rotated, when the protrusion is outside the recess, the protrusion abuts against the rotating portion, the elastic piece is forced away from the rotating portion, and the locking tongue extends into the card slot of the box - shaped housing, realizing the locking of the plug - and - play module and the box - shaped housing; when the protrusion is inside the recess, the elastic piece rebounds towards the rotating portion under the action of elastic force, the locking tongue disengages from the card slot of the box - shaped housing, and under the action of an external force, the plug - and - play module disengages from the box - shaped housing.

[0011] In some embodiments, a notch is provided on the side end face, and the elastic piece moves closer to or away from the rotating portion in the notch.

[0012] In some embodiments, the pluggable module body includes: a pluggable module body and a fixed base disposed at the tail end of the pluggable module body, wherein the electrical connector of the pluggable module body is led out through the fixed base and is electrically connected to the mating connector at the bottom of the box-type housing.

[0013] A third aspect of this application provides an electronic device, comprising: a box-type housing, wherein a slot is provided on the side wall of the box-type housing; and a pluggable module as described above, wherein the locking tongue of the pluggable module extends into or disengages from the slot to such that the pluggable module is in a locked state or an unlocked state with the box-type housing.

[0014] Beneficial effects of the embodiments in this application:

[0015] The locking mechanism, pluggable module, and electronic device provided in this application embodiment have a rotating part that acts as a pivot, rotating relative to the annular protrusion.

Detailed implementation manners

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0035] In view of the problems existing in the background technology, this application aims to design a convenient unlocking and plugging mechanism, reduce the operating space, so as to help users perform quick unlocking and plugging maintenance work and improve the user experience of the product.

[0036] The first aspect of this application provides a locking mechanism 1, such as... Figure 1 As shown, the locking mechanism 1 includes a rotating handle 11 and a support assembly 12. The rotating handle 11 includes a rotating part 111, which has at least one recess 1111 circumferentially arranged, and a handheld part 112 fixedly connected to the rotating part 111. The support assembly 12 has an annular protrusion 1211 supporting the rotating part 111, and at least one spring piece 1221 disposed on the edge of the support assembly 12. Each spring piece 1221 has a protrusion 1222 on the side near the rotating part 111, the protrusion 1222 protruding towards the rotating part 111, and at least one locking tongue 1223 on the side away from the rotating part 111. The rotating part 111 of the rotating handle 11 is sleeved on the annular protrusion 1211 of the bracket assembly 12, and rotates along the annular protrusion 1211 under the drive of the hand handle 112. When the protrusion 1222 is outside the recess 1111, the protrusion 1222 abuts against the rotating part 111, the spring piece 1221 is forced away from the rotating part 111, and the locking tongue 1223 extends into the slot 51 of the box-type housing 5, thereby locking the locking mechanism 1 and the box-type housing 5. When the protrusion 1222 is inside the recess 1111, the spring piece 1221 rebounds towards the rotating part 111 under the action of elastic force, and the locking tongue 1223 disengages from the slot 51 of the box-type housing 5, thereby unlocking the locking mechanism 1 and the box-type housing 5. The cooperation between the locking tongue 1223 and the box-type housing 5 can be found in the following reference. Figure 2 .

[0037] In this embodiment, the rotating part 111 acts as a pivot, rotating relative to the annular protrusion 1211. Furthermore, during rotation, the position of the recess 1111 relative to the protrusion 1222 can be changed, allowing the recess 1111 to be directly opposite or misaligned with the protrusion 1222. This enables the unlocking or locking function to be completed during rotation, resulting in a simple structure, high reliability, and low susceptibility to failure. The locking and unlocking of this locking mechanism 1 are achieved through rotation, featuring a novel structure, convenient operation, and high reliability. Unlocking can be completed in a single step, improving ease of use and allowing the pluggable module using this locking mechanism 1 to be quickly unlocked and removed from the housing 5, facilitating maintenance and replacement. During rotation, the rotating handle 11 directly acts on the unlocking part without intermediate transmission, further simplifying the structure and ensuring greater safety and reliability. When pulling out the pluggable module 1, force can also be applied by using the hand-held part 112 of the rotating handle 11, combining unlocking and force application into one, further simplifying the structure and saving space.

[0038] In some embodiments, reference Figure 1 At least one edge of the bracket assembly 12 is provided with at least one curved elastic claw 1224. When the rotating part 111 is sleeved on the annular protrusion 1211, the clamping part 1225 of the curved elastic claw 1224 abuts against the rotating part 111, and the arched part 1226 of the elastic claw 1224 abuts against the inner wall of the box-type housing 5. Under the pressure of the inner wall of the box-type housing 5, the clamping part 1225 presses against the rotating part 111.

[0039] The clamping part 1225 hugs the rotating part 111 inward, which can apply a certain preload to the rotating part 111 to prevent the rotating part 111 from shaking during rotation.

[0040] Preferably, the resilient claws 1224 are evenly arranged circumferentially along the rotating part 111, so that the rotating part 111 is always in a central position. In addition, the arched portion 1226 of the resilient claws 1224 contacts the inner wall of the box-type housing 5, which reduces the contact area between the pluggable module and the box-type housing 5 during insertion and removal, thereby reducing sliding friction. This saves effort and prevents the pluggable module from shaking inside the box-type housing 5.

[0041] As one possible implementation, refer to Figure 3 , Figure 4The rotating part 111 has two recesses 1111, and the bracket assembly 12 has two spring pieces 1221, with the spacing between the spring pieces 1221 matching the spacing between the recesses 1111, so that when the rotating handle 11 is rotated, the two spring pieces 1221 can simultaneously engage with the two recesses 1111. Preferably, the two recesses 1111 are symmetrically arranged, and the two spring pieces 1221 are also symmetrically arranged, so that when the pluggable module is locked to the box-type housing 5, the force is more evenly distributed, and stress concentration is less likely to occur. The two spring pieces 1221 can be respectively provided on both sides of the bracket assembly 12 in the width direction.

[0042] Of course, the rotating part 111 may also be provided with three or more recesses 1111. In order to ensure uniform force distribution, the three or more recesses 1111 should be evenly arranged. Correspondingly, the spring piece 1221 is also provided with three or more.

[0043] In some embodiments, reference Figure 4 Each spring piece 1221 may be provided with two locking tongues 1223, which are arranged at intervals along the height direction of the spring piece 1221. Optionally, the two locking tongues 1223 are located on both sides of the height direction H of the spring piece 1221.

[0044] Of course, each spring piece 1221 may also be provided with three locking tongues 1223, and the line connecting the three locking tongues 1223 along the height direction H can be a straight line or a triangle.

[0045] The elastic claw 1224 can be formed by bending to give it an outward elastic force, so that it can always maintain contact with the box housing 5 after entering the box housing 5, and hold the rotating part 111 tightly under the pressure of the box housing 5.

[0046] In some embodiments, such as Figure 4 As shown, the support assembly 12 includes a support 121 and a protective net 122. The support 121 and the protective net 122 are two independent structures, or, as... Figure 5 As shown, the bracket 121 and the protective net 122 are integrally formed structures.

[0047] The bracket 121 and the protective net 122 are two independent structures, meaning that the structures on the bracket assembly 12 are integrated onto two different mounting plates. This simplifies the structure of the bracket 121 and the protective net 122, making manufacturing easier. The bracket assembly 12 itself is an independent structure, meaning that all the structures on the bracket assembly 12 are integrated onto a single mounting plate. This reduces the use of one component, which helps to lower costs and reduce the size of the locking mechanism 1.

[0048] In some embodiments, reference Figure 4 , Figure 6 , Figure 7, when the bracket 121 and the protective net 122 are two independent structures, the bracket 121 has an annular convex portion 1211 and a mounting plate 1212 with a central through-hole. The annular convex portion 1211 is fixed in the middle of the mounting plate 1212. The edge of the mounting plate 1212 slightly protrudes from the outer side of the annular convex portion 1211. The inner diameter of the annular convex portion 1211 is adapted to the central through-hole. The edge of the mounting plate 1212 is provided with a first type of groove 1212a matching the number of the elastic pieces 1221 and a second type of groove 1212b matching the number of the elastic clamping claws 1224. The protective net 122 is adapted to the outer edge of the mounting plate 1212 and has at least one elastic piece 1221 and at least one elastic clamping claw 1224. Each elastic piece 1221 is respectively embedded in a first type of groove 1212a, so that the protrusion 1222 on the elastic piece 1221 can abut against the rotating portion 111. Each elastic clamping claw 1224 is respectively embedded in a second type of groove 1212b, so that the clamping portion 1225 of each elastic clamping claw 1224 abuts against the rotating portion 111, and the arched portion 1226 abuts against the inner wall of the box-shaped housing 5.

[0049] The bracket assembly 12 is divided into two parts, the bracket 121 and the protective net 122. The two cooperate with each other to have relatively high strength. And for any one of the components, the structure is relatively simple, which is convenient for processing and manufacturing. The mounting plate 1212 has a central through-hole, and the protective net 122 has uniformly distributed mesh holes 1227, which will not form an obstruction to the pluggable module body 2 in the axial direction of the rotating portion 111, which is beneficial to the heat dissipation of the pluggable module body 2. When the pluggable module is a fan module, a relatively large air outlet area of the air duct can be maintained, and the air outlet efficiency can be improved. In addition, the uniformly distributed mesh holes 1227 on the protective net 122 can also play a filtering role to avoid inhaling impurities and the like.

[0050] Among them, as Figure 7 shown, the protective net 122 can be an integrally formed structure. First, the mesh hole part, as well as the shape and size required for the elastic pieces 1221 and the elastic clamping claws 1224, are formed by stamping, and then the elastic pieces 1221 and the elastic clamping claws 1224 are formed by bending. In this way, the connection strength between the elastic pieces 1221, the elastic clamping claws 1224 and the mesh hole part can be improved, which is beneficial to extending the service life of the protective net 122.

[0051] In some embodiments, as Figure 8 、 Figure 9 shown, on one side of the rotating portion 111 close to the handheld portion 112, there is a "day" - shaped panel 113. The outer edge of the "day" - shaped panel 113 matches the circumferential edge of the rotating portion 111. The handheld portion 112 is in a "T" shape and is arranged on the horizontal plate of the "day" - shaped panel 113. The horizontal portion of the "T" - shaped handheld portion 112 is parallel to the horizontal plate.

[0052] In this embodiment, the locking mechanism 1 further includes a front panel 3. The front panel 3 includes a front end face 31 and a side end face 32. The front end face 31 and the side end face 32 enclose a structure of a receiving cavity. The rotating part 111 of the handle 11 is located in the receiving cavity and is limited by the front panel 3 to prevent the rotating part 111 from detaching from the annular protruding part 1211. There is an installation hole 322 on the side end face 32. The arched part 1226 abuts against the inner wall of the box-shaped housing 5 through the installation hole 322.

[0053] The rotating handle 11 includes a "day" - shaped panel 113 provided near the handheld part 112 of the rotating part 111. The outer edge of the "day" - shaped panel 113 matches the circumferential edge of the rotating part 111, making the internal hollow area of the rotating handle 11 larger. The horizontal part of the "T" - shaped handheld part 112 is in the shape of a "one", and the horizontal plate on the "day" - shaped panel 113 is also in the shape of a "one". In this way, the horizontal part and the horizontal plate are overlapped along the axial direction of the rotating part 111, and the shielding area of the internal hollow area of the rotating part 111 is less. When it is installed at the front end of the pluggable module, a relatively large air outlet area can be maintained. When the pluggable module is a fan module or other heat dissipation modules, a relatively large air duct air outlet area can be maintained, improving the air outlet efficiency.

[0054] When the locking mechanism 1 in this embodiment is used in cooperation with a classic fan module, due to the small space occupied by its handheld part 112, the drawback of blocking the wind of the fan is significantly optimized and improved.

[0055] In the second aspect of the present application, a pluggable module is provided. Referring to Figure 10 、 Figure 11 and Figure 12 , the pluggable module is pluggably installed in the box - shaped housing 5 of the electronic device. The pluggable module can be a module with a certain function, including but not limited to a fan module, a power module, a single - board module, etc. The electronic device includes but not limited to various IT products, such as network servers, etc.

[0056] Specifically, in combination with Figure 8 、 Figure 10 、 Figure 11 and Figure 12The pluggable module includes the locking mechanism 1, the pluggable module body 2, the front panel 3, and the fastener 4. The front panel 3 includes a front end face 31 and a side end face 32, which form a receiving cavity. The front end face 31 has a panel through hole 311. The rotating part 111 in the locking mechanism 1 is placed in the receiving cavity, and the handle part 112 is exposed to the outside through the panel through hole 311. The fastener 4 fixes the pluggable module body 2, the locking mechanism 1, and the front panel 3 as a whole. When the exposed handle part 112 is rotated, and the protrusion 1222 is outside the recess 1111, the protrusion 1222 abuts against the rotating part 111, the spring piece 1221 is forced away from the rotating part 111, and the locking tongue 1223 extends into the slot 51 of the box-type housing 5, thereby locking the pluggable module to the box-type housing 5. Figure 13 The diagram shows the pluggable module and the housing 5 in a locked state; Figure 13 In this state, rotating the handle 112 90° clockwise unlocks the pluggable module from the housing 5. Specifically, when the protrusion 1222 is within the recess 1111, the spring 1221 springs back towards the rotating part 111 under elastic force, disengaging the locking tongue from the slot 51 of the housing 5. Under external force, the pluggable module disengages from the housing 5. The direction of the external force is away from the front end face 31.

[0057] In this embodiment, the rotating part 111 is positioned between the front panel 3 and the bracket assembly 12. The front panel 3, the bracket assembly 12, and the pluggable module body 2 are fixed together by fasteners 4. The inner diameter of the panel through hole 311 is slightly smaller than the outer diameter of the rotating part 111. This ensures that when the rotating handle 11 is pulled outward, it is restricted by the front panel 3, preventing it from detaching from the annular protrusion 1211. The slightly smaller inner diameter of the panel through hole 311 compared to the outer diameter of the rotating part 111 also increases the air outlet area of ​​the front panel 3, improving the heat dissipation of the pluggable module. One end of the handheld part 112 is located outside the front panel 3 through the panel through hole 311, and the other end is connected to the rotating part 111. Placing one end of the handheld part 112 outside the front panel 3 facilitates its operation.

[0058] Understandably, when the pluggable module has no special requirements for heat dissipation, the panel through hole 311 of the front panel 3 can be used only for the handheld part 112 to pass through. In this way, the diameter of the panel through hole 311 of the front panel 3 is matched with the diameter of the handheld part 112. The handheld part 112 passes through the front panel 3 and is located outside the rotating part 111. It is used to restrict the movement of the rotating part 111 along its axial direction and prevent it from disengaging from the annular protrusion 1211. This further ensures the repeatability of the rotation trajectory of the rotating handle 11 and ensures that the unlocking function is normal.

[0059] In this embodiment, the fastener 4 not only secures the front panel 3 to the bracket assembly 12, but also secures the pluggable module body 2 of the locking mechanism 1, further simplifying the structure of the pluggable module. The fastener 4 can be located on the edge of the front panel 3. For example, when the front panel 3 is square or rectangular, it can be located in the attachment area at the four corners, or in the attachment area at the two corners of the diagonal.

[0060] In some embodiments, reference Figure 8 , Figure 9 and Figure 10 A notch 321 is provided on the side end face 32. The spring piece 1221 moves closer to or away from the rotating part 111 within the notch 321. The shape of the notch 321 is adapted to the shape of the spring piece 1221. The general shape of the spring piece 1221 can be rectangular. The spring piece 1221 moves closer to or away from the rotating part 111 through the notch 321. The notch 321 can avoid the movement of the spring piece 1221 and prevent interference between the rotating part 111 and the spring piece 1221.

[0061] In some embodiments, reference Figure 11 , Figure 12 The pluggable module body 2 includes a pluggable module body 21 and a fixing seat 22 located at the tail end of the pluggable module body 21. The electrical connector 211 of the pluggable module body 21 is led out through the fixing seat 22 and is plugged into the mating connector 52 at the bottom of the box housing 5 for electrical connection.

[0062] The electrical connector 211 of the pluggable module body 21 is led out through the fixing seat 22. The fixing seat 22 not only acts as a shell to protect the internal structure from impact damage, but also prevents dust and dirt. In addition, the fixing seat 22 has a corresponding engaging structure for the electrical connector 211. During the process of leading the electrical connector 211 out through the fixing seat 22, it can be fixed so that it can be electrically connected to the mating connector 52 at the bottom of the box-type housing 5. The mating of the electrical connector 211 and the mating connector 52 can also fix and limit the pluggable module.

[0063] During pluggable module assembly, first assemble the rotating handle 11 with the bracket 121 to form a shape as shown. Figure 14 Assembly A is then assembled with the protective net 122 to form a structure as shown below. Figure 15 Assembly 2B is then assembled with front panel 3 to form as shown. Figure 16 The locking mechanism 1 is then used, and the fastener 4 passes through the screw holes on the locking mechanism 1 and the screw holes on the pluggable body 2 to lock the locking mechanism 1 to the pluggable module body 2, thus completing the assembly of the pluggable module. Figure 10 As shown.

[0064] A third aspect of this application provides an electronic device, which may be, but is not limited to, a server, a switch enclosure, a micro data center, an energy storage battery cabinet, etc. (See reference...) Figure 11 , Figure 12 The electronic device includes a housing 5 and a pluggable module. The pluggable module is the pluggable module described above. The side wall of the housing 5 is provided with a slot 51. The locking tongue 1223 of the pluggable module extends into or disengages from the slot 51 so that the pluggable module is in a locked state or in an unlocked state with the housing 5.

[0065] In this embodiment, the pluggable module switches between locking and unlocking functions by rotating the handle 11. This simple operation improves unlocking convenience and facilitates maintenance and replacement of the pluggable module. During rotation, the handle 11 directly acts on the unlocking part without intermediate transmission, resulting in a simpler structure and higher safety and reliability. Furthermore, after unlocking, the pluggable module body 2 can be pulled out of the housing 5 using the handheld part 112, facilitating force application. The handheld part 112 serves as both a force-applying component and an unlocking component.
