[0042] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] The air conditioner fan mounting structure provided in this embodiment is used for quickly disassembling and replacing the cross-flow fan of the air conditioner.

[0044] like Figure 1 、 Figure 2 The figure shows a specific embodiment of the air conditioner fan mounting structure provided in this embodiment, comprising: a housing 1, a driver 3, and a fan body 4. The housing 1 is provided with a housing chamber 2 for mounting various air conditioner components. An opening is provided on one end face of the housing 1 in the longitudinal direction, communicating with the housing chamber 2. During installation, the fan body 4 can be installed from the opening side into the housing 1. The driver 3 is disposed within the housing chamber 2 of the housing 1, facing away from the opening, with the driving end of the driver 3 facing the opening. The driver 3 is a motor, and the driving end of the driver 3 refers to the motor's drive shaft. When the fan body 4 is pushed inward from the opening, a second fixing member 6 on the fan body 4 connects with the driving end of the driver 3. A first fixing member 5 is rotatably mounted on one axial end of the fan body 4, and a second fixing member 6 is rotatably mounted on the other axial end. When the fan body 4 is installed from the opening, the first fixing member 5 is removably mounted to the housing 1, and the second fixing member 6 abuts against the housing chamber 2 to support the fan body 4. The fan body 4 is connected to the driving member 3. When the fan body 4 is pushed inward for installation, the fan body 4 is plug-connected with the driving end of the driving member 3.

[0045] When the fan body 4 needs to be installed, the second fixing member 6 is first installed with the fan body 4, and the second fixing member 6 on the fan body 4 is pushed inward from the opening position until the fan body 4 is plugged into and connected with the driving end of the driving member 3. Then, the first fixing member 5 is installed to the other end of the fan body 4, and then the first fixing member 5 is installed on the housing 1. At this time, the fan body 4 is in a suspended state, that is, the fan body 4 can rotate relative to the first fixing member 5 and the second fixing member 6.

[0046] By arranging the fan body 4 on the first fixing member 5 and the second fixing member 6, the second fixing member 6 is used to support the fan body 4, and the first fixing member 5 is used to install the fan body 4 on the housing 1. When disassembly is required, it is only necessary to remove the first fixing member 5 from the housing 1, and then pull the entire fan body 4 out of the accommodating chamber 2 of the housing 1 to complete the disassembly of the fan body 4, which is more convenient. At the same time, when installation is required, it is only necessary to move the second fixing member 6 toward the driving member 3, and then push the fan body 4 toward the driving motor until the fan body 4 is plugged into and connected with the driving end of the driving member 3.

[0047] like Figure 3 As shown, in this embodiment, a limiting groove is provided on the end face of the first fixing member 5 facing the driving member 3. The limiting groove is a circular groove, the axis of the circular groove is parallel to the length direction of the housing 1, and the limiting groove extends inward along the axial direction of the first fixing member 5 in the direction away from the driving member 3. The first bearing is installed in the limiting groove. After installation, the outer ring of the first bearing is clamped in the limiting groove, and the inner ring of the first bearing is connected to one end of the fan body 4. A cylinder is provided on the fan body 4, and the cylinder can be inserted into the inner ring of the first bearing during installation. When the fan body 4 rotates, the fan body 4 is rotatably connected to the first fixing member 5 through the first bearing, making the rotation more convenient. In addition, as an alternative embodiment, a cylinder is extended toward one side of the fan body 4, and a limiting groove is provided on the end face of the cylinder.

[0048] Specifically, the first bearing on the first fixing member 5 is a rubber bearing 15, which can reduce vibration and noise. In addition, the first bearing on the first fixing member 5 can also be a roller first bearing.

[0049] like Figure 4 As shown, in this embodiment, the second fixing member 6 includes: a second bearing, the outer ring of the second bearing abuts against the inner wall of the accommodating chamber 2 of the housing 1, so that when the fan body 4 rotates, the outer ring of the second bearing always abuts against the end face of the accommodating chamber 2 of the housing 1 to support the fan body 4. One end of the inner ring of the second bearing is plug-connected to the driving end of the driving member 3, and the other end is detachably connected to the fan body 4, thereby realizing a quick connection between the fan body 4 and the driving member 3. When the driving shaft of the driving member 3 rotates, the fan body 4 is driven to rotate by the inner ring of the second bearing. In addition, as an alternative embodiment, the second fixing member 6 can also be a second bearing seat, and a snap-in groove for snapping in the second bearing seat is provided on the accommodating chamber 2 of the housing 1 to prevent the second bearing seat from rotating. Afterwards, one end of the second bearing seat is rotatably connected to the fan body 4, and the other end is connected to the driving end of the driving member 3.

[0050] like Figure 5As shown, in this embodiment, a plurality of positioning members 14 are provided radially inwardly extending from the inner wall of the accommodating chamber 2. The positioning members 14 extend along the axial direction of the accommodating chamber 2 from the opening to a position close to the driving member 3. The cross-section of the positioning members 14 is square. The outer ring of the second fixing member 6 is provided with a positioning groove that is engaged and fixed with the positioning members 14. During installation, the second fixing member 6 is installed at one end of the fan body 4, and the positioning groove on the second fixing member 6 is aligned with the positioning member 14 so that the positioning groove of the second fixing member 6 is engaged with the positioning member 14. The fan body 4 is then pushed into the housing 1. The positioning members 14 prevent the outer ring of the second bearing from rotating when the fan body 4 rotates, thereby avoiding unnecessary noise problems. In addition, the number of positioning members 14 is not limited, and those skilled in the art can select a different number according to actual needs, such as three, four, etc. In addition, the shape of the positioning member 14 can also be dovetail, rectangular, or circular.

[0051] like Figure 4 As shown, in this embodiment, an extension member 7 is provided on the inner ring of the second bearing on the second fixing member 6, extending horizontally toward one side of the fan body 4. A snap-in groove for accommodating the extension member 7 is provided at one end of the fan body 4, which is recessed axially inward. The extension member 7 is inserted into the snap-in groove and secured by a fastener 8. When installing the fan body 4, the second fixing member 6 is first installed to one axial end of the fan body 4. After the extension member 7 on the inner ring of the second bearing is inserted into the snap-in groove, the fastener 8 passes through the fan body 4 in the radial direction of the extension member 7 and is threadedly connected to the extension member 7, thereby securing the extension member 7. In addition, as an alternative embodiment, the inner ring of the second bearing can also be directly fixedly connected to the axial end of the fan body 4.

[0052] like Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown, in this embodiment, a groove 9 is provided on the housing 1, and a clamping member 10 that is clamped and connected to the groove 9 is provided on the first fixing member 5, and the first fixing member 5 is disc-shaped. The first fixing member 5 fixes the first fixing member 5 and the fan body 4 by clamping the clamping member 10 to the groove 9 on the housing 1. When disassembly is required, it is only necessary to disengage the first fixing member 5 from the clamping state of the groove 9 to achieve the separation of the first fixing member 5, the fan body 4 and the second fixing member 6 from the housing 1. In addition, as an alternative embodiment, the clamping member 10 may not be provided, and the body may be fixed to the housing 1 directly by passing a bolt through the first fixing member 5.

[0053] like Figure 6As shown, in this embodiment, the clamping member 10 includes: a first connecting plate 11 and a second connecting plate 12 arranged symmetrically, and a third connecting plate 13 is provided between the lower end of the first connecting plate 11 and the lower end of the second connecting plate 12. In other words, the two ends of the third connecting plate 13 in the length direction are respectively fixedly connected to the first connecting plate 11 and the second connecting plate 12. The second connecting plate 12 can be elastically deformed toward the first connecting plate 11 under the action of an external force. The upper end of the first connecting plate 11 is fixedly connected to the outer peripheral surface of the first fixing member 5. When the clamping member 10 needs to be clamped into the groove 9, the first connecting plate 11, the second connecting plate 12, and the third connecting plate 13 are embedded in the groove 9 to fix the first fixing member 5. This installation method is faster and more convenient. In addition, as a replaceable embodiment, the groove 9 is circular, and an inwardly recessed notch is provided on the inner end face of the groove 9. The clamping part 10 is a circular disk that can be embedded in the groove 9. An annular ridge that is engaged with the notch is provided on the outer end face of the circular disk. During installation, the circular disk is embedded in the groove 9, and the annular ridge is clamped into the notch.

[0054] like Figure 6 As shown, in this embodiment, the outer end surfaces of the first connecting plate 11 and the second connecting plate 12 are provided with a slot for snapping onto the edge of the housing 1. That is, the slot is provided on a side end surface of the first connecting plate 11 and the second connecting plate 12 that is relatively far away from each other. When the first connecting plate 11 and the second connecting plate 12 are embedded in the groove 9, the slot can snap onto the edge of the housing 1, thereby quickly securing the first fixing member 5. When disassembly is required, it is only necessary to move the second connecting plate 12 toward the first connecting plate 11. At this time, the first connecting plate 11, the second connecting plate 12, and the third connecting plate 13 are elastically deformed. After disassembly, the first connecting plate 11 and the second connecting plate 12 can be disengaged from the slot of the housing 1, thereby quickly removing the first fixing member 5. After disassembly, due to the elastic deformation, the first connecting plate 11, the second connecting plate 12, and the third connecting plate 13 will return to their original state. In addition, as an alternative embodiment, two ridges are provided on the outer end surfaces of the first connecting plate 11 and the second connecting plate 12, and the edge of the housing can be snapped between the two ridges to achieve fixation.

[0055] like Figure 10 As shown, in this embodiment, the clamping member 10 is a bolt, and multiple bolts are provided. The bolts pass through the outer end surface of the first fixing member 5 and then threadedly connect with the housing 1, thereby quickly securing the first fixing member 5. When disassembly is required, the first fixing member 5 can be disengaged by simply unscrewing the bolts, thereby quickly withdrawing the fan body 4 from the accommodating chamber 2. In addition, as an alternative embodiment, the clamping member 10 can also be other parts such as screws and self-tapping screws.

[0056] Specifically, such as Figure 11 、 Figure 12 As shown, the clamping member 10 can also be configured as a latch, and a slot is provided on the circumferential end surface of the first fixing member 5. The latch passes through the housing 1 and is connected to the slot, thereby realizing rapid fixation of the first fixing member 5. The axial end of the latch is provided with a cylinder with a diameter larger than the diameter of the latch, and the outer end surface of the cylinder is provided with anti-slip grooves. After the latch is plugged into the housing 1, the cylindrical part is located on the outside of the housing 1. When it is necessary to pull out the latch, pinch the outer end surface and core of the cylinder with your hands to separate the latch from the slot and the housing 1. In addition, as an alternative embodiment, a ring can also be provided at the end of the latch, and when it is necessary to pull it out, the latch can be pulled out as a whole by passing a finger through the hole in the middle of the ring.

[0057] like Figure 1 、 Figure 4 As shown, in this embodiment, the driving member 3 is a motor, and a coupling is installed on the driving shaft of the motor. A polygonal column structure is installed at the front end of the coupling. The polygonal column structure is plug-in connected to the inner ring of the second fixing member 6. That is to say, the inner ring of the second fixing member 6 is provided with a groove corresponding to the polygonal column structure. When installing the fan body 4, the groove of the inner ring of the second fixing member 6 is aligned with the polygonal column structure, and then the connection is achieved after plugging it in. Specifically, the polygonal main structure is a regular hexagonal structure. If the polygonal column structure does not correspond to the groove during installation, the fan body 4 can be slightly rotated and reconnected. In addition, as an alternative embodiment, the polygonal column structure is not limited and can also be a regular pentagon, a regular quadrilateral, a regular heptagon, etc. The driving shaft of the motor can also be designed as a polygonal shaft head.

[0058] Installation method of the air conditioner fan mounting structure: During installation, first install the second fixing member 6 and the fan body 4. Push the second fixing member 6 of the fan body 4 inward from the opening until the inner ring of the second fixing member 6 of the fan body 4 is plugged into the drive shaft of the driver 3. The positioning groove on the outer ring of the second fixing member 6 is located in the positioning member 14 of the accommodating cavity 2 on the housing 1. Then, install the first fixing member 5 to the other end of the fan body 4, and then install the first fixing member 5 to the housing 1. The installation of the fan body 4 is completed. At this point, the fan body 4 is in a suspended state and can rotate relative to the first fixing member 5 and the second fixing member 6.

[0059] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
