As shown in fig. 1 and 2, the embodiment of the present application first provides a fan assembly 100, in which a fan 30 set price is applied to an inverter. The inverter includes a housing 200, a fan assembly 100, and an electronic device, wherein the fan assembly 100 is disposed outside the housing 200, and the electronic device is disposed inside the housing 200. In the example of the present application, the case 200 has a front surface and a rear surface, and the rear surface of the case 200 is further provided with a heat sink 300, and the heat sink 300 may be a fin type heat sink.

Fig. 3 is a schematic structural diagram of the support frame according to the present application at a first view angle. Fig. 4 is a schematic structural diagram of a fan and a mounting member according to the present application at a first viewing angle.

Referring to fig. 3 and 4, in the present embodiment, the fan assembly 100 includes a support frame 10, a mounting member 20, a fan 30 and a locking member 40. Wherein, the support frame 10 is disposed in the housing 200, a receiving cavity 101 is formed between the support frame 10 and the housing 200, and an inlet/outlet 131 communicating with the receiving cavity 101 is formed on one side of the support frame 10. The mounting member 20 is slidably disposed on the support frame 10 along the first direction, the mounting member 20 is provided with a mounting position 21, and one end of the mounting member 20 is provided with a cover plate 22. The first direction is the X-axis direction in the illustration. The fan 30 is disposed at the mounting location 21. Retaining member 40 is disposed on cover 22, and retaining member 40 has a locked condition and an unlocked condition.

When the mounting member 20 moves to the first position (as shown in fig. 1) and the locking member 40 is in the locked state, the mounting member 20 is completely contained in the containing cavity 101, the cover 22 covers the inlet and outlet 131, and the locking member 40 is fixedly connected with the support frame 10. When the locking member 40 is in the unlocked state and the mounting member 20 is moved to the second position (as shown in fig. 2), the mounting member 20 is at least partially exposed to the receiving cavity 101 through the inlet and outlet 131, so that the mounting position 21 and the fan 30 are exposed to the support frame 10.

In the example of the present application, when the mount 20 is in the second position, the mount 20 is completely exposed to the support frame 10, i.e., the mount 20 is entirely separated from the support frame 10. Thus, shielding of the support frame 10 to the mounting member 20 is reduced, and more space is provided for facilitating maintenance and replacement of the fan 30 by a user. In another embodiment, when the mounting member 20 is in the second position, the mounting member 20 may also be partially exposed from the supporting frame 10, i.e. the end of the mounting member 20 near the cover 22 is pulled away from the supporting frame 10, and the end of the mounting member 20 far from the cover 22 is further accommodated in the supporting frame 10 to prevent the mounting member 20 from falling.

Normally, the mount 20 is in the first position and the cover 22 covers the access opening 131. The locking member 40 is in a locked state, so that the cover 22 and the support frame 10 are relatively fixed, and the mounting member 20 is prevented from sliding relative to the support frame 10, so that the fan 30 is fixed in the support frame 10 for blowing.

In the event that maintenance or replacement of the fan 30 is required, the user may switch the locking member 40 to the unlocked state and move the mounting member 20 to the second position to withdraw the mounting member 20 from the access opening 131 such that the mounting location 21 and the fan 30 are exposed to the support frame 10. After the fan 30 is serviced or replaced, the user may move the mounting member 20 to the first position to push the mounting member 20 from the access opening 131 back into the receiving cavity 101, return the fan 30 to the support frame 10, and then switch the locking member 40 to the locked state.

Thus, when the fan 30 is maintained or replaced, the casing 200 or the support frame 10 is not required to be disassembled and assembled, and the fan 30 can be exposed out of the support frame 10 or reinstalled in the support frame 10 only by switching the locking state/unlocking state of the locking piece 40 and pulling the mounting piece 20, so that the operation is simpler and more convenient, the disassembly and assembly difficulty is reduced, and the maintenance and replacement of the fan 30 are rapidly completed. Not only reduces maintenance time, reduces cost of maintenance, has still solved simultaneously because of the extra problem that changes portion fan 30 and dismantle and cause, reduces the risk that relevant accessory or wire rod lost the damage, reduces the wasting of resources.

In some embodiments, the fan 30 is provided with a first wire terminal 31, the first wire terminal 31 being for electrical connection with a second wire terminal 32. The second wire terminal 32 is used for electrical connection with a control element inside the housing 200. Illustratively, the housing 200 is provided with a wire hole through which the second wire terminal 32 is inserted, and the supporting frame 10 covers the wire hole. The first wire terminal 31 and the second wire terminal 32 adopt a detachable terminal structure, and may specifically be a snap-in structure.

When the mounting member 20 is at the second position, the fan 30 pulls the first wire terminal 31 to expose the first wire terminal 31 and the second wire terminal 32 to the support frame 10, the user can detach the first wire terminal 31 and the second wire terminal 32 to directly disconnect the electrical connection between the fan 30 and the control element, and after the maintenance and replacement of the fan 30 are completed, the first wire terminal 31 and the second wire terminal 32 are reconnected to reestablish the electrical connection between the fan 30 and the control element, thereby facilitating the operation, avoiding wire confusion, and reducing the risks of misoperation and accessory loss.

In some embodiments, the direction of the air blowing of the fan 30 is a third direction, and the mount 20 is disposed perpendicular to the third direction. The heat sink 300 has a plurality of fins 301, the plurality of fins 301 are spaced apart along the first direction, and the fins 301 extend along the third direction. The first direction and the second direction are both provided with included angles with the third direction, and the third direction is the Z-axis direction in the illustration. In this way, the blowing air of the fan 30 can pass through the gaps among the fins 301, thereby further improving the heat dissipation performance of the heat sink 300.

In some embodiments, the mounting member 20 is generally plate-shaped and the mounting member 20 is generally disposed extending in the first direction. The mount 20 is provided with burring portions 24 on both sides in the second direction, and the burring portions 24 are formed by bending from both side edges of the mount 20. The second direction is the Y-axis direction in the illustration. Wherein the flange portion 24 can increase the thickness at both side edges of the mount 20 and can guide and position the mount 20 in cooperation with other structures.

In some embodiments, the mounting member 20 is provided with an air outlet 211 at the mounting location 21 and a plurality of mounting holes distributed around the air outlet 211. The blades of the fan 30 are arranged opposite to the air outlet 211, the fan 30 is provided with a plurality of fixing screws 33, and the plurality of fixing screws 33 are respectively in threaded connection with a plurality of mounting holes so as to fix the fan 30 to the mounting position 21.

In the example of the present application, the number of the mounting locations 21 is 1, i.e., the mounting member 20 can mount one fan 30. In other embodiments, the number of the mounting locations 21 may be greater than 1, that is, the mounting member 20 may simultaneously mount a plurality of fans 30, which may be specifically configured according to the practical application, which is not limited in the present application.

In some embodiments, one end of the mount 20 is provided with a cover plate 22 and the other end of the mount 20 is provided with a riser 23. The cover plate 22 and the vertical plate 23 are respectively formed by bending from two ends of the mounting piece 20, and the cover plate 22 and the vertical plate 23 are parallel to the third direction.

In some embodiments, the area of the cover plate 22 is greater than the area of the access opening 131 so that the cover plate 22 can cover the access opening 131. When the mounting member 20 is in the first position, the cover 22 abuts against the side surface of the supporting frame 10 to limit the maximum travel of the mounting member 20 into the accommodating cavity 101.

In some embodiments, the side of the cover 22 remote from the mount 20 is provided with a handle 221. When the mount 20 is in the first position, the handle 221 is outside of the support stand 10. The handle 221 can be used for a user to apply force to pull the cover plate 22 and the mounting piece 20, so that the user can conveniently disassemble and assemble the cover plate.

In some embodiments, the locking member 40 has a plurality of locking members 40 spaced apart along the length of the cover 22. The locking screw 41 penetrates through the cover plate 22 and is rotatably connected with the cover plate 22.

Illustratively, retaining member 40 is a retaining screw 41, and retaining screw 41 is press-staked to cover 22. The locking screw 41 has a screwing end and a threaded end, and the screwing end of the locking screw 41 is located on one surface of the cover plate 22 away from the support frame 10 for a user to apply force to screw. The threaded end of the locking screw 41 is located on the side of the cover plate 22 facing the support frame 10 to be screwed with the support frame 10.

The support frame 10 is provided with screw holes 132 corresponding to the locking screws 41. When the locking screw 41 is screwed to the corresponding screw hole 132, the locking screw 41 is in a locked state. When the locking screw 41 is contracted to be loose from the corresponding screw hole 132, the locking screw 41 is in an unlocked state.

Thus, by screwing the locking screw 41, the locking screw 41 can be screwed into the screw hole 132 or loosened from the screw hole 132, thereby facilitating the disassembly and assembly operations of the user.

In the example of the present application, the locking member 40 is detachably coupled to the supporting bracket 10 using a screw structure. In other embodiments, the locking member 40 may also be a snap-fit structure, an interference fit structure, a latch structure, etc., which is not limited in this regard.

In some embodiments, the area of the riser 23 is less than or equal to the area of the access opening 131, such that the riser 23 can pass through the access opening 131 to allow the entire support bracket 10 to be withdrawn from the access opening 131.

Fig. 5 is a schematic structural diagram of the support frame according to the present application at a second view angle. Fig. 6 is a schematic structural diagram of the fan and the mounting member according to the present application at a second viewing angle.

Referring to fig. 5 and fig. 6 together, in some embodiments, a communication port 102 communicating with the accommodating cavity 101 is provided on a side of the support frame 10 facing the heat sink 300, and an air permeable port 121 communicating with the accommodating cavity 101 is provided on a side of the support frame 10 away from the communication port 102. The blowing air of the fan 30 passes through the communication port 102 and the ventilation port 121. In this way, the air flow of the fan 30 can blow through the gaps between the fins 301 through the communication ports 102 and the ventilation ports 121, thereby further improving the heat dissipation performance of the heat sink 300.

In the example of the present application, the fan assembly 100 and the radiator 300 are arranged in the vertical direction, the support frame 10 is positioned below the radiator 300, the communication port 102 is positioned at the top of the support frame 10, and the ventilation port 121 is positioned at the bottom of the support frame 10.

The number and positions of the ventilation ports 121 are set corresponding to the number and positions of the fans 30. When the mounting member 20 is in the second position, one surface of the fan 30 faces the corresponding air vent 121 through the air outlet 211.

In some embodiments, the panel 11 and the housing 200 are respectively adjacent to both sides of the mount 20 in the second direction to limit the mount 20 in the second direction. Illustratively, the faceplate 11 and the housing 200 are respectively proximate to the flange portions 24 on either side of the mount 20.

During the movement of the mounting member 20 along the first direction, the panel 11 and the housing 200 limit the movement range of the mounting member 20 in the second direction, and play a role in guiding and limiting the movement of the mounting member 20 in the second direction, so as to avoid the blocking of the mounting member 20 during the movement. The position of the mount 20 is positioned to ensure that the fan 30 can be aligned with the position of the ventilation opening 121 after the mount 20 is assembled.

Illustratively, the first side plate 13 and the second side plate 14 are respectively formed by bending from two sides of the housing 200, and the first side plate 13 and the second side plate 14 are both bolted to the housing 200. The first side plate 13 is provided with an inlet and outlet 131 at one end close to the bottom plate 12. The first side plate 13, the second side plate 14 and the panel 11 are located close to the housing 200, and form a communication port 102 together with the housing 200.

The first side plate 13 is fixed with a lock nut by press riveting, and the lock nut forms a screw hole 132 on the surface of the first side plate 13.

The first side plate 13 and the panel 11 are both bolted and fixed with the partition plate 15.

The first side plate 13, the second side plate 14, the panel 11, the bottom plate 12 and the housing 200 form a housing cavity 101, the partition plate 15 is located inside the housing cavity 101 and divides the housing cavity 101 into a first layer and a second layer, wherein the first layer is used for accommodating the mounting piece 20 and the fan 30, and the second layer is used for accommodating the first wire terminal 31 of the fan 30.

In some embodiments, the spacer 15 is spaced from the base plate 12 along a third direction, and the spacer 15 and the base plate 12 cooperate to limit the mount 20 along the third direction. Illustratively, the partition 15 and the bottom plate 12 are respectively adjacent to both sides of the riser 23 in the third direction to limit the mount 20 in the third direction.

In the moving process of the mounting piece 20 along the first direction, the bottom plate 12 and the partition plate 15 limit the moving range of the vertical plate 23 in the third direction, and the moving of the mounting piece 20 in the third direction plays a role in guiding and limiting, so that the mounting piece 20 is prevented from being blocked during moving. The position of the mount 20 is positioned to ensure that the fan 30 can be aligned with the position of the ventilation opening 121 after the mount 20 is assembled.

In some embodiments, the partition 15 is provided with vents 151, and the number and positions of the vents 151 correspond to the number and positions of the fans 30. When the mount 20 is in the second position, a side of the fan 30 remote from the ventilation opening 121 faces the corresponding ventilation opening 151. In this way, the blowing air flow of the fan 30 may pass through the communication port 102, the air vent 151, and the air vent 121.

In some embodiments, the partition 15 is provided with a threading hole 152, and the surface of the partition 15 is provided with thread protecting teeth 153, and the thread protecting teeth 153 are distributed along the edge of the threading hole 152. Illustratively, the threading hole 152 is formed at an end of the partition 15 near the inlet and outlet 131, and the threading hole 152 is in communication with the inlet and outlet 131. The threading hole 152 is used for passing through the first wire terminal 31 and the second wire terminal 32. The wire guard teeth 153 are serrated and attached to both sides of the separator 15, and the wire guard teeth 153 protect the first wire terminal 31 and the second wire terminal 32 from being cut by the cut surfaces at the threading holes 152.

In some embodiments, the end of the partition 15 remote from the access opening 131 is provided with a catch 154.
