[0002] The fan module is a commonly used module device. Its main function is to meet the needs of quick plug-in and pull-out of the fan and indicate the fan's working status. It is generally composed of a fan body, an operating indicator light, a handle, a snap-on fixing structure, a module housing, etc.

[0003] At present, in the design of server equipment, the unlocking mechanism 6 and the handle of the rear fan module are independently set, which means that when disassembling and maintaining the fan, these two different modules need to be operated separately. Since the unlocking module and the handle exist independently, they both need to occupy a certain physical space on the fan module, resulting in a reduction in the lateral space utilization of the server chassis. At the same time, the independent unlocking and handle structures will block part of the fan blades, thereby indirectly reducing the effective ventilation area and affecting the heat dissipation effect.

[0004] Therefore, how to provide an unlocking structure, a fan module and a chassis in which the unlocking structure and the handle are integrated is a problem that urgently needs to be solved. Utility Model Content

[0029] Embodiment 1

[0030] Reference Figure 1 -Attached Figure 5 , Embodiment 1 of the present invention proposes an unlocking structure for locking or unlocking a first body 1 and a second body 2, the unlocking structure comprising: a stop component, which has a connecting column 3 extending along a first direction A and penetrating through a front panel 11 of the first body 1, the connecting column 3 penetrating and rotatably connected to the first body 1, a hooking portion 31 being provided at one end of the connecting column 3, the hooking portion 31 corresponding to a limiting opening 21 of the second body 2; and a hand-held component 4, mounted at the other end of the connecting column 3, for driving the stop component to rotate so that the hooking portion 31 switches between a first position and a second position; when the hooking portion 31 is in the first position, the hooking portion 31 is located at the limiting opening 21 to lock the first body 1 to the second body 2; when the hooking portion 31 is in the second position, the hooking portion 31 is away from the limiting opening 21, and the first body 1 and the second body 2 are in an unlocked state.

[0031] Specifically, Figure 2-Figure 5As shown, the positional relationship between the first body 1 and the second body 2 can be: the second body 2 has a receiving cavity, the first body 1 is arranged in the receiving cavity, and the operator can pull out or push the first body 1 into the receiving cavity of the second body 2 along the first direction A. The length of the connecting column 3 of the stop component extending along the first direction A can be set according to actual needs, and the diameter size of the connecting column 3 can be set according to the thickness size of the front panel 11 along the first direction A. The specific type of the connecting column 3 is not limited here, and the connecting column 3 can be specifically a cylinder or a prism. The front panel 11 of the first body 1 is provided with a through hole, and the connecting column 3 can pass through the front panel 11 along the first direction A through the through hole so that the hooking portion 31 at one end thereof corresponds to the limiting opening 21 of the second body 2. The hooking portion 31 here can be specifically a plate-like structure, a columnar structure or a J-shaped structure fixed to the connecting column 3 by bolts or welding and the extending direction is perpendicular to the extending direction of the connecting column 3. The specific shape of the hooking portion 31 is not limited here. The position of the limiting opening 21 on the second body 2 corresponds to the position of the hook portion 31, such as: the limiting opening 21 is located on the top wall or side wall of the second body 2, the limiting opening 21 passes through the top wall or side wall of the second body 2, or the depth of the limiting opening 21 passes through part of the top wall or side wall of the second body 2 along the third direction C. In addition, the size and shape of the limiting opening 21 can be set according to the size and shape of the hook portion 31. This embodiment is explained by taking the limiting opening 21 located on the top wall of the second body 2 as an example. When the hook portion 31 is in the first position, the hook portion 31 can extend along the third direction C to the limiting opening 21 so that it is clamped in the limiting opening 21 to achieve locking of the first body 1 and the second body 2. The clamping here can be specifically in two situations. The first situation is: when the limiting opening 21 passes through the top wall of the second body 2 along the third direction C, the hook portion 31 extends along the third direction C to the limiting opening 21 and the end of the hook portion 31 away from the connecting column 3 is flush with the side of the top wall away from the accommodating cavity, or is higher than the side of the top wall away from the accommodating cavity, or the height of the end of the hook portion 31 away from the connecting column 3 is located between the side of the top wall away from the accommodating cavity and the side of the top wall close to the accommodating cavity. The second situation is: when the depth of the limit opening 21 penetrates part of the top wall of the second body 2 along the third direction C, the hook portion 31 extends to the limit opening 21 along the third direction C and the height of the end of the hook portion 31 away from the connecting column 3 is located between the side of the top wall away from the accommodating cavity and the side of the top wall close to the accommodating cavity. When the hook portion 31 is in the second position, the hook portion 31 is away from the limit opening 21, so that the first body 1 and the second body 2 can be separated freely, and the first body 1 and the second body 2 are in an unlocked state. The shape of the hand-grip portion of the hand-held component 4 can be a plate-like structure or a spherical structure. The specific shape of the hand-held component 4 is not limited here and can be set according to the operating habits of the operator. In addition, the hand-held component 4 can be connected to the connecting column 3 by bolt connection or welding.When the grip portion of the handheld component 4 is a plate-shaped structure, the position where the handheld component 4 is connected to the connecting column 3 can be the center point of the grip portion, or any end of the grip portion.

[0032] The present application provides an unlocking structure, a fan module and a chassis, which are used to lock or unlock a first body 1 and a second body 2. The unlocking structure includes a stopper and a handheld component 4. The connecting column 3 of the stopper penetrates and is rotatably connected to the first body 1. One end of the connecting column 3 is provided with a hooking portion 31. When an operator wants to lock or unlock the first body 1 and the second body 2, the operator only needs to operate the handheld component 4 at the other end of the connecting column 3 with one hand, and the handheld component 4 is rotated with the axis of the connecting column 3 to drive the hooking portion 31 to rotate so that the hooking portion 31 is located at the limiting opening 21 of the second body 2 or away from the limiting opening 21, so as to achieve the locking or unlocking of the first body 1 and the second body 2. To lock or unlock the first body 1 and the second body 2 through the unlocking structure, the operator only needs to rotate the handheld component 4 with one hand and can pull the first body 1 away from the second body 2 or push the first body 1 close to the second body 2 through the handheld component 4. The unlocking structure has the functions of unlocking and pulling handles at the same time, which reduces the ventilation area occupied by the additional installation of the handle and saves the occupied space.

[0033] In some embodiments, the unlocking structure further includes: a groove 32, which is provided on the outer surface of the connecting column 3 and extends along the first direction A; a block portion, the hand-held component 4 is provided with a through hole 42 extending along the first direction A and the hand-held component 4 is sleeved on the connecting column 3 through the through hole 42, and the hand-held component 4 is provided with a block portion adapted to the groove 32 to limit the relative rotation of the hand-held component 4 relative to the connecting column 3 along the axis of the connecting column 3; and an elastic telescopic component 5, which is sleeved on the connecting column 3 and the two ends of the elastic telescopic component 5 are respectively pressed against the hand-held component 4 and the front panel 11; An avoidance groove 22 extends along the second direction B from the side of the limiting opening 21 away from the hand-held component 4, the avoidance groove 22 is connected to the limiting opening 21 and the width of the avoidance groove 22 along the first direction A is smaller than the width of the limiting opening 21 along the first direction A; wherein, the elastic telescopic member 5 can be telescopic along the first direction A so that the hand-held component 4 can slide relative to the connecting column 3 along the first direction A, so that the hook portion 31 is located on the side of the limiting opening 21 close to the hand-held component 4 or on the side of the limiting opening 21 away from the hand-held component 4; the second direction B is perpendicular to the first direction A and the longitudinal direction.

[0034] Specifically, Figure 2-Figure 3As shown, the handheld component 4 is provided with a through hole 42 extending along the first direction A, the diameter of the through hole 42 is adapted to the diameter of the connecting column 3, the handheld component 4 is sleeved on the connecting column 3 through the through hole 42, and the specific position of the through hole 42 can be set at the center of the hand grip of the handheld component 4 or at any end of the hand grip. The outer surface of the connecting column 3 is provided with a groove 32 extending along the first direction A, and the handheld component 4 is provided with a block part adapted to the groove 32, the block part can be integrally formed with the handheld component 4, and the specific setting position of the block part can be the inner side of the hole wall of the through hole 42. The block part can slide in the groove 32 along the first direction A to make the handheld component 4 slide relative to the connecting column 3 along the first direction A. In addition, the block part can also limit the relative rotation of the handheld component 4 relative to the connecting column 3 along the axis of the connecting column 3. Such a structure can make the connecting column 3 rotate as the handheld component 4 rotates along the axis of the connecting column 3. The width of the side of the limit opening 21 close to the hand-held component 4 along the second direction B is adapted to the width of the hook portion 31 along the second direction B. The side of the limit opening 21 away from the hand-held component 4 extends a evasion groove 22 along the second direction B. The length of the evasion groove 22 extending along the second direction B is set according to the size of the hook portion 31. No specific limitation is made here. The function of the evasion groove 22 is mainly to provide an evasion space for the rotation of the hook portion 31. The width of the evasion groove 22 along the first direction A is less than the width of the limit opening 21 along the first direction A. The width of the evasion groove 22 along the first direction A is at least equal to the width of the hook portion 31 along the first direction A. An elastic telescopic member 5 is provided between the hand-held component 4 and the front panel 11. One end of the elastic telescopic member 5 abuts against the hand-held component 4 and the other end of the elastic telescopic member 5 abuts against the front panel 11. The elastic telescopic member 5 can be a spring. The telescopic amount of the elastic telescopic member 5 along the first direction A can be set as needed. When the hand-held component 4 is not subjected to external pressure along the first direction A, the elastic telescopic member 5 is in the initial telescopic state or the initial elongated state, and the hook portion 31 is on the side of the limit opening 21 close to the hand-held component 4. At this time, the hook portion 31 is restricted by the limit opening 21 and cannot be rotated by the rotation of the hand-held component 4. When the hand-held component 4 is subjected to external pressure along the first direction A, the elastic telescopic member 5 is compressed, and the hand-held component 4 slides relative to the connecting column 3 along the first direction A, thereby driving the hook portion 31 to move in the limit opening 21 along the first direction A from the side of the limit opening 21 close to the hand-held component 4 to the side of the limit opening 21 away from the hand-held component 4. At this time, the hand-held component 4 is rotated clockwise or counterclockwise along the axis of the connecting column 3, thereby driving the hook portion 31 to rotate clockwise or counterclockwise along the axis of the connecting column 3. After the rotation is completed, the external force is cancelled, and the elastic telescopic member 5 returns to the initial telescopic state or the initial elongated state.By providing the avoidance groove 22 at the limit opening 21 and providing the elastic retractable member 5 between the hand-held component 4 and the front panel 11, the hook portion 31 is moved to the side of the limit opening 21 away from the hand-held component 4 after applying pressure along the first direction A to the hand-held component 4, and is free from the restriction of the limit opening 21 close to the hand-held component 4, so that the hook portion 31 can rotate with the rotation of the hand-held component 4. Such a structure effectively avoids the accidental rotation of the hook portion 31 at inappropriate times, and reduces the risk of accidents caused by operational errors.

[0035] In some embodiments, a sleeve 43 is extended from the edge of the through hole 42 of the handheld component 4 along the first direction A and toward the hook portion 31 , and two ends of the elastic telescopic component 5 are respectively pressed between the sleeve 43 and the front panel 11 .

[0036] Specifically, Figure 2-Figure 3 As shown, a sleeve 43 extends from the edge of the through hole 42 of the handheld component 4 along the first direction A and toward the hooking portion 31. The length of the sleeve 43 along the first direction A can be set according to the length of the connecting column 3, and the inner diameter of the sleeve 43 is adapted to the outer diameter of the connecting column 3. When the handheld component 4 is provided with the sleeve 43, the block portion can be provided on the inner wall of the sleeve 43. In addition, a plurality of grooves 32 extending along the first direction A can be provided at intervals on the connecting column 3, and a plurality of block portions corresponding to and adapted to the plurality of grooves 32 on the connecting column 3 can be provided on the inner wall of the sleeve 43. Such a design can make the handheld component 4 more stable when rotating and driving the connecting column 3 to rotate, and prevent the block portion from slipping off the groove 32 of the connecting column 3. The sleeve 43 extends along the first direction A and covers the connecting column 3. Compared with directly using the through hole 42, it provides a larger contact area and can reduce shaking when the handheld component 4 rotates. This can more evenly distribute the force exerted on the handheld component 4 during rotation or movement, reduce local stress concentration, and improve the stability of the overall structure.

[0037] In some embodiments, two avoidance grooves 22 extend relatively along the second direction B on the side of the limit opening 21 away from the hand-held component 4, the two avoidance grooves 22 are connected to the limit opening 21, and the width of the two avoidance grooves 22 along the first direction A is smaller than the width of the limit opening 21 along the first direction A.

[0038] Specifically, Figure 3As shown, two avoidance grooves 22 are relatively extended along the second direction B on the side of the limit opening 21 away from the hand-held component 4. The length of the two avoidance grooves 22 extending along the second direction B can be set according to actual needs. The extension length of the two avoidance grooves 22 along the second direction B is not specifically limited here, as long as it can provide avoidance for the rotation of the hook part 31. The width of the two avoidance grooves 22 along the first direction A is less than the width of the limit opening 21 along the first direction A, and the width of the two avoidance grooves 22 along the first direction A is at least equal to the width of the hook part 31 along the first direction A. The provision of two avoidance grooves 22 allows the hook part 31 to rotate in both clockwise and counterclockwise directions, thereby improving the flexibility of the unlocking structure.

[0039] In some embodiments, the hooking portion 31 includes two protrusions 311 , which are arranged opposite to each other and extend in directions away from the connecting column 3 .

[0040] Specifically, Figure 3 or Figure 5 As shown, the hooking part 31 includes two protrusions 311, and the two protrusions 311 can be integrally formed with the connecting column 3 as a whole, or the two protrusions 311 can be detachably connected to the connecting column 3 by bolts or buckles. Compared with the hooking part 31 with only one protrusion 311, the hooking part 31 is provided with two protrusions 311, which improves the flexibility of the unlocking structure. The operator can complete the locking of the first body 1 and the second body 2 by rotating the handheld component 4 to rotate any protrusion 311 to the limit opening 21 so that it is stuck in the limit opening 21. Moreover, even if one protrusion 311 cannot be used due to wear or other reasons, the other protrusion 311 can still ensure normal operation, which increases the redundancy of the unlocking structure.

[0041] In some embodiments, an end of each protrusion 311 away from the connecting post 3 is provided with a curved surface structure 3111 that bulges in a direction away from the connecting post 3 .

[0042] Specifically, Figure 5 As shown, the protruding surface is provided with an arc surface structure 3111. The arc surface structure 3111 is used as a guiding design. When the hook portion 31 approaches the limit opening 21, the protrusion 311 can be accurately aligned and slide into or out of the limit opening 21 through its contour. This design helps to reduce the alignment time and ensure that the docking can be completed smoothly even in poor visibility or fast operation, thereby improving the accuracy and efficiency of the operation. When the protrusion 311 is fully inserted into the limit opening 21, the midline portion of the arc surface structure 3111 protrudes from the side of the second body 2 away from the accommodating cavity, forming an additional physical barrier. This design strengthens the locking effect between the hook portion 31 and the limit opening 21 by adding a protruding portion, effectively preventing accidental disengagement under the action of external force, and improving the stability and safety of the overall structure.

[0043] In some embodiments, the extending direction of the grip portion of the handheld component 4 is perpendicular to the extending direction of the two protrusions 311 .

[0044] Specifically, Figure 3 As shown, the extension direction of the hand grip of the handheld component 4 is perpendicular to the extension direction of the two protrusions 311. When the operator rotates the hand grip to lock the first body 1 and the second body 2, at this time, the extension direction of the protrusion 311 is parallel to the third direction C, the extension direction of the hand grip is parallel to the second direction B, and the hand grip is parallel to the edge of the front panel 11, which means that the side of the hand grip will not go too deep into the device or block the air outlet. The problem of poor heat dissipation caused by blocking is effectively avoided, and the stability and efficiency of the device operation are maintained.

To lock or unlock the first body 1 and the second body 2 through the unlocking structure, the operator only needs to rotate the handheld component 4 with one hand and can pull the first body 1 away from the second body 2 or push the first body 1 close to the second body 2 through the handheld component 4.

Since the unlocking structure is set on one side of the front panel 11 of the fan module, multiple fan modules can be arranged at intervals along the second direction B or multiple fan modules can be arranged without intervals along the second direction B. The distance between two adjacent fan modules can be set according to actual needs, and no specific limitation is made here. Two adjacent fan modules of the chassis with an unlocking structure can be arranged without intervals, saving the horizontal layout space between the fan modules.
