[0091] Some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0092] Example

[0094] The electronic device 100 may be a switch, a server, etc., and some electronic components (such as a motherboard, a hard disk, etc.) inside the electronic device 100 will generate heat during operation. The fan module 10 can dissipate heat for the electronic device 100 to ensure stable and long-term operation of the electronic device 100.

[0095] See also Figure 1-Figure 3This embodiment provides a fan module 10, which includes a fan assembly 12, a locking mechanism 13 and a plurality of brackets 14. Other electronic devices (such as a motherboard, a hard disk, etc.) inside the electronic device 100 can be arranged in the space outside the fan module 10 inside the main housing 11. The number of the locking mechanisms 13 can be consistent with the number of the brackets 14, that is, a set of locking mechanisms 13 is arranged on each bracket.

[0096] It should be noted that Figure 3 The fan assembly 12 is hidden and not shown.

[0097] The main shell 11 forms a receiving chamber Q1 , a portion of which is mainly used to install structures such as the fan assembly 12 and the bracket 14 , and the other portion is used to accommodate other electronic components (such as a motherboard, a hard disk, etc.) of the electronic device 100 .

[0098] The main shell 11 is provided with a first opening K1 facing the first direction Z and a second opening K2 facing the second direction Y. The first opening K1 and the second opening K2 are connected to the accommodating cavity Q1 respectively. The first direction Z is perpendicular to the second direction Y. Optionally, the main shell 11 in this embodiment is a substantially rectangular box-shaped structure, consisting of six panels. The first opening K1 and the second opening K2 are respectively opened on a group of adjacent surfaces of the rectangular parallelepiped, such as Figure 3 As shown, the first opening K1 is arranged on the top surface of the cuboid, the second opening K2 is arranged on one side surface of the cuboid, and the second opening K2 is connected to the first opening K1.

[0099] The plurality of brackets 14 are arranged at intervals along the third direction X, the third direction X is perpendicular to the first direction Z and the second direction Y, and the plurality of brackets 14 are slidably fitted to the main shell 11 along the second direction Y, and can slide into and out of the accommodating chamber Q1 from the second opening K2. Optionally, the accommodating chamber Q1 is provided with a plurality of partitions 44 spaced in sequence along the third direction X, the plurality of partitions 44 are respectively connected to the main shell 11, and a slide rail space Q3 is defined between adjacent partitions 44. The plurality of brackets 14 are slidably arranged in the plurality of slide rail spaces Q3 along the second direction Y, and can be independently installed in the slide rail space Q3 or slide out of the slide rail space Q3. For example Figure 3 As shown in FIG. 1 , there are five partitions 44 , and four slide rail spaces Q3 are defined between the five partitions 44 . The four slide rail spaces Q3 are used to respectively cooperate with four brackets 14 .

[0100] During assembly, each partition 44 can be installed into the accommodating cavity Q1 from the first opening K1 and fixed to the main shell 11, and then each bracket 14 can be installed in turn into the slide rail space Q3 between the partitions 44. Then, the fan assembly 12 can be assembled so that the fan assembly 12 covers the first opening K1 and is partially fitted in the bracket 14.

[0101] See also Figure 4-Figure 6The fan assembly 12 includes a mounting plate 15 and a plurality of fan modules 16. The plurality of fan modules 16 are arranged at intervals along the third direction X and are slidably connected to the mounting plate 15 along the second direction Y. The mounting plate 15 is detachably connected to the main housing 11 and covers the first opening K1 (see FIG. Figure 1 ).

[0102] See also Figure 8 , Fig. 9 and Fig.10 ,in, Fig. 9 The edge of the bracket 14, the fan module 16 and the locking mechanism 13 is connected. Figure 2 A view looking down toward the first opening K1 in the Z direction. To facilitate the display of some features, Fig. 9 The sliding plate 40 (see below) of the central fan module 16 is hidden and not shown.

[0103] The bracket 14 is provided with a fan installation chamber Q2, which is open toward the first opening K1 (see Fig.10 , the top of the bracket is not closed and forms an opening) to allow the fan module 16 to be placed in the fan installation chamber Q2 of the bracket 14 along the first direction Z. The plurality of fan modules 16 are matched one by one into the fan installation chambers Q2 of the plurality of brackets 14 along the first direction Z; the fan module 16 has an air inlet K3 and an air outlet K4 opposite to each other along the second direction Y, and the fan assembly 12 can rotate as a whole to adjust the fan module 16 so that the air inlet K3 side is close to the second opening K2 or the air outlet K4 side is close to the second opening K2.

[0104] The locking mechanism 13 is used to lock the fan module 16 to the corresponding bracket 14, so that the fan module 16 locked to the bracket 14 can slide out of the accommodating chamber Q1 with the bracket 14. In addition, the locking mechanism 13 can be unlocked, so that the fan module 16 that slides out of the accommodating chamber Q1 with the bracket 14 can be taken out and turned to a state where the air inlet K3 or the air outlet K4 corresponds to the second opening K2 in the state of being unlocked from the bracket 14.

[0105] In this embodiment, the bracket 14 includes a bracket 17, an end plate 18 and two side plates 19, the two side plates 19 are respectively connected to the two sides of the bracket 17 in the width direction (third direction X), the lower end of the end plate 18 is connected to the bracket 17, and the two sides of the end plate 18 are respectively connected to the two side plates 19, and the bracket 17, the end plate 18 and the two side plates 19 enclose a fan installation chamber Q2, and the fan installation chamber Q2 opens toward the first direction Z. Optionally, the end plates 18 of the plurality of brackets 14 correspond to the second opening K2 to block the second opening K2 (see Figure 1), the end plate 18 is provided with an air hole K6. Depending on the installation direction of the fan module 16, the air hole K6 may correspond to the air inlet K3 or the air outlet K4 of the fan module 16 for air flow to pass through. The air hole K6 may include a plurality of small holes distributed on the end plate 18, and these small holes may be in a honeycomb shape or other shapes, which are not limited here. Optionally, guide plates 51 extending along the first direction Z are respectively connected to the middle position of the inner side of the two side plates 19 in the long direction (second direction Y), and the spacing between the two guide plates 51 is approximately equal to the width of the fan module 16, so that it is convenient to guide the fan module 16 along the first direction Z into the fan installation chamber Q2.

[0106] The locking mechanism 13 includes a hook 20 and a blocking member 21 connected to the bracket 14 at intervals along the second direction Y. The hook 20 is connected to the side of the support plate 17 away from the end plate 18, and the hook 20 includes a vertical extension section 22 vertically connected to the support plate 17 and a horizontal extension section 23 connected to the end of the vertical extension section 22 and extending along the second direction Y. The blocking member 21 is rotatably connected to the end plate 18, and the blocking member 21 includes a blocking block 24 extending into the fan installation chamber Q2.

[0107] In this embodiment, the fan module 16 includes a fan 25 and an adapter plate 26. The adapter plate 26 is provided with two clamping holes 27 spaced apart along the second direction Y. The two clamping holes 27 are centrally symmetrically arranged about the center point of the adapter plate 26 to ensure that the positions of the two clamping holes 27 are swapped after the adapter plate 26 rotates 180°. The clamping hole 27 is a bar-shaped hole extending along the second direction Y, and an expanded hole with one end enlarged may be provided to facilitate the entry of the hook 20. The adapter plate 26 is provided with two limit blocks 28. The two limit blocks 28 are respectively arranged at the two ends of the adapter plate 26 along the second direction Y, and are centrally symmetrical about the center point of the adapter plate 26 to ensure that the positions of the two limit blocks 28 are swapped after the adapter plate 26 rotates 180°. When the fan module 16 is fitted in the fan installation chamber Q2, the hook 20 passes through one of the engaging holes 27, the blocking block 24 abuts against the limiting block 28 along the second direction Y, and the transverse section 23 blocks the area of ​​the adapter plate 26 outside the engaging hole 27, so as to prevent the adapter plate 26 from being disengaged from the support plate 17 along the first direction Z. The blocking member 21 can rotate to make the blocking block 24 leave the limiting block 28, so as to allow the adapter plate 26 to move relative to the support plate 17 along the second direction Y to a position where the transverse section 23 completely corresponds to the engaging hole 27, thereby allowing the fan module 16 to be disengaged from the bracket 14 along the first direction Z.

[0108] In this embodiment, the fan module 16 further includes two fan connectors 29. When any one of the fan connectors 29 is turned on, the fan module 16 is powered on. The two fan connectors 29 are respectively arranged at the two ends of the adapter plate 26 along the second direction Y, and are centrally symmetrical about the center point of the adapter plate 26 to ensure that the positions of the two fan connectors 29 are swapped after the adapter plate 26 rotates 180°. In this way, when the fan module 16 is in a forward air outlet state or a reverse air outlet state, there is a fan connector 29 that can be used to connect the fan module to electricity.

[0109] The blocking block 24 includes a side block 30 and a top block 31 which are perpendicular to each other. The side block 30 is used to abut the limit block 28 along the second direction Y, and the top block 31 is used to abut the limit block 28 along the first direction Z. By abutting the limit block 28 along the second direction Y and the first direction Z, respectively, the fan module 16 is stably limited on the bracket 14. Optionally, a chamfer 52 is provided on a side of the side block 30 away from the top block 31, so that when the blocking block 24 rotates to press the limit block 28, the side block 30 can be guided to gradually press the limit block 28 along the second direction Y.

[0110] The blocking member 21 further includes a rotating handle 42 and a rotating shaft section 43. The rotating shaft section 43 rotatably passes through the end plate 18, and one end of the rotating shaft section 43 is connected to the blocking block 24, and the other end is connected to the rotating handle 42. The rotating handle 42 is located outside the fan installation chamber Q2. In this way, the user can rotate the blocking block 24 by rotating the rotating handle 42 located outside the fan installation chamber Q2, so that the blocking block 24 is pressed against the limit block 28 or away from the limit block 28.

[0111] In other embodiments, the blocking member 21 may be configured in other forms, as long as it can be pressed against the limit stopper 28 or away from the limit stopper 28. For example, the blocking member 21 may adopt a translational motion instead of a rotational motion. The blocking member 21 may also be configured as a structure with a self-locking function, so that when the blocking member 21 locks the limit stopper 28, it can achieve self-locking.

[0112] In other embodiments, the limit stopper 28 may be omitted, and the fan module 16 may be limited by the mutual limitation between the blocking member 21 and the fan 25 , the adapter plate 26 or other components of the fan module 16 .

[0113] Optionally, the limit stopper 28 is L-shaped, and includes a vertically connected horizontal plate 49 and a vertical plate 50. The horizontal plate 49 is superimposed and fixed on the adapter plate 26, and the vertical plate 50 extends vertically to limit the position of the stopper 24.

[0114] See also Fig. 9 and Figure 3The bracket 14 has a connecting ear 45, which is used to be locked to the partition 44 by a locking member 46 (such as a screw) when the bracket 14 is fitted into the rail space Q3. In this way, each bracket 14 is locked to the partition 44 by the locking member 46 and will not be easily disengaged. When it is necessary to extract a certain bracket 14, the locking member 46 is first loosened to extract the bracket 14, while the other brackets 14 remain locked to the partition 44.

[0115] In other embodiments, the connecting ear 45 may also be locked to the main housing 11 or other positions, which is not limited here.

[0116] In other embodiments, the connecting ear 45 may also be omitted, and the bracket 14 is locked by other means.

[0117] See also Figure 2 and Figure 4-Figure 7 In this embodiment, the two sides of the accommodating cavity Q1 along the third direction X are respectively provided with supporting plates 32, and the opposing surfaces of the two supporting plates 32 are respectively set as rack surfaces P1 extending along the second direction Y, and the tooth grooves C1 of the rack surfaces P1 penetrate the supporting plates 32 along the first direction Z. A handle groove C2 is provided on the side of the mounting plate 15 away from the fan module 16, and a through hole K5 penetrating the mounting plate 15 is provided on the bottom surface of the handle groove C2. A handle assembly 33 is connected to the mounting plate 15, and the handle assembly 33 includes a handle rod 34, a connecting rod 35 and a displacement gear 36; the connecting rod 35 passes through the through hole K5, and one end of the connecting rod 35 away from the fan module 16 is connected to the handle rod 34, and the other end is connected to the displacement gear 36, so that the force applied to the handle rod 34 can drive the handle assembly 33 to move along the axial direction of the connecting rod 35 or rotate around the connecting rod 35. The displacement gear 36 meshes with the rack surface P1, so that the rotation of the displacement gear 36 can drive the mounting plate 15 and the plurality of fan modules 16 to move relative to the main housing 11 along the second direction Y, so that the adapter plate 26 of the fan module 16 moves relative to the hook 20 to the position where the transverse section 23 blocks the adapter plate 26 or withdraws from the position where the transverse section 23 blocks the adapter plate 26. The displacement gear 36 corresponds to the plate surface of the mounting plate 15 close to the fan module 16 along the axial direction, and the cross-sectional size of the displacement gear 36 is larger than the through hole K5, so that the lifting handle rod 34 can drive the displacement gear 36 to support the mounting plate 15 along the axial direction, so as to lift or lower the fan assembly 12.

[0118] A plurality of guide rails 37 are connected to one side surface of the mounting plate 15 . Each guide rail 37 extends along the second direction Y, and the plurality of guide rails 37 are sequentially spaced and distributed along the third direction X. A first magnetic attraction member 38 is disposed near each guide rail 37 .

[0119] The fan module 16 also includes a sliding plate 40 connected to the fan 25. Thus, the fan module 16 in this embodiment generally includes a fan 25 located in the middle and a sliding plate 40 and an adapter plate 26 respectively connected to both sides of the fan 25 in the thickness direction. The fan 25 is used to generate airflow when powered, the sliding plate is used to form a sliding fit with the guide rail 37 on the mounting plate 15, and the adapter plate 26 is used to be locked to the bracket 14 through the locking mechanism 13, and the structure is simple and reasonable, and it is easy to use.

[0120] The sliding plate 40 is provided with a second magnetic member 41. The sliding plate 40 can be slidably matched with the guide rail 37, and can be relatively fixed to the mounting plate 15 by the attraction of the first magnetic member 38 and the second magnetic member 41. The guide rail 37 is penetrated along the second direction Y, so that the fan module 16 locked to the bracket 14 can slide out of the guide rail 37 along the second direction Y with the bracket 14 to detach from the mounting plate 15 when the bracket 14 is slid and withdrawn relative to the main housing 11 along the second direction Y. In this embodiment, each sliding plate 40 is provided with a second magnetic member 41 on both sides along the width direction, and the two second magnetic members 41 are attracted to the adjacent first magnetic members 38 respectively.

[0121] In other embodiments, the number of the first magnetic members 38 and the second magnetic members 41 may also be set as required and is not limited here.

[0122] The following describes the method of using the electronic device 100 in this embodiment.

[0123] In the initial use state, the installation state of the fan module 10 is shown in Figure 1 At this time, the airflow direction of the fan module 16 is as follows Figure 1 As shown by the hollow arrow A1 marked on the middle mounting plate 15.

[0124] When the airflow direction of all fan modules 16 needs to be switched, the first step is to rotate the blocking members 21 on each bracket 14 to release the displacement restriction of the limit block 28 on the fan module 16 along the second direction Y by the blocking block 24; the second step is to pull out the two handle assemblies 33 from the fan assembly 12 with both hands respectively. During the pulling-out process, the displacement gear 36 slides axially relative to the tooth groove C1 and still maintains a state of meshing with the rack surface P1; the third step is to rotate the handle rod 34 to drive the displacement gear 36 to rotate. Due to the meshing cooperation between the displacement gear 36 and the supporting plate 32, when the supporting plate 32 is fixed to the main shell 11, the displacement gear 36 The rotation relative to the supporting plate 32 will cause the displacement gear 36 to displace along the extension direction (second direction Y) of the rack surface P1, thereby causing the entire handle assembly 33 and even the fan assembly 12 as a whole to displace relative to the main housing 11 along the second direction Y. This displacement causes the hook 20 to correspond to the engaging hole 27 along the first direction Z, thereby releasing the restriction of the lateral extension section 23 of the hook 20 on the displacement of the adapter plate 26 along the first direction Z. In the fourth step, continue to pull the handle assembly 33 along the first direction Z, and drive the entire fan assembly 12 to detach from the main housing 11 and each bracket 14 through the handle assembly 33. In the fifth step, rotate the entire fan assembly 12 horizontally 180° to Fig.11 After the fan assembly 12 is in the state of being replaced, the fan assembly 12 is reinstalled into the main housing 11 and each bracket 14, and then the above steps are reversed to re-realize the horizontal extension section 23 of the hook 20 to limit the adapter plate 26 along the first direction Z, and the blocking member 21 to limit the limit block 28 along the second direction Y. At this time, the directions of the air inlet K3 and the air outlet K4 of each fan module 16 of the fan assembly 12 are interchanged, and the airflow direction of the fan assembly 12 is changed to Fig.11 The hollow arrow A1 on the mounting plate 15 shows the direction.

[0125] This switching method can switch the airflow direction of all fan modules 16 at one time, has high efficiency, can be operated without tools, and is easy to use.

[0126] When a single fan module 16 needs to be replaced, first loosen the locking member 46 at the connecting ear 45, and pull the handle 48 connected to the end plate 18 of the bracket 14 along the second direction Y, so that the bracket 14 and the fan module 16 locked thereon can be pulled out together, so as to replace the fan module 16. Fig.12 It should be noted that, in the process of pulling out the bracket 14 , the magnetic force between the first magnetic member 38 and the second magnetic member 41 needs to be overcome. In addition, in the process of pulling out the bracket 14 , the sliding plate 40 of the fan module 16 is guided by the guide rail 37 on the mounting plate 15 .

[0127] In summary, the electronic device 100 in the embodiment of the present application only needs to be equipped with a set of fan components 12 to achieve heat dissipation by bidirectional airflow, reducing the material management requirements and the occupation of material storage space. In addition, the fan module 10 of the electronic device 100 can easily and quickly change the direction of the fan component 12 as a whole, and can also easily replace a single fan module 16, with a simple structure and easy use.

Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
