[0046] Figure 1This is a schematic structural diagram of an indoor unit of an air conditioner according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 8 This utility model provides a motor mounting device for an air conditioner, comprising a first cover 100 and a second cover 200. The first cover 100 defines a first mounting cavity 110 with a forward-facing opening, and a slot 120 with a downward-facing opening is provided on the upper part of the first cover 100; the second cover 200 defines a second mounting cavity 210 with a rearward-facing opening, and the second cover 200 is disposed on the front side of the first cover 100. The first cover 100 and the second cover 200 enclose each other so that the first mounting cavity 110 and the second mounting cavity 210 form a mounting space for accommodating a motor 300, and define a motor 300 shaft hole that extends horizontally. The upper part of the second cover 200 is provided with a plug-in portion 220 that engages with the slot 120; the lower parts of the first cover 100 and the second cover 200 are snap-fitted together.

[0047] In this embodiment, the first cover 100 is installed on the rear side of the motor 300, and the second cover 200 is installed on the front side of the motor 300. The upper parts of both are engaged with the insertion part 220 via a slot 120, and the lower parts are snapped together to form an assembly structure. During assembly, the insertion part 220 of the second cover 200 is first inserted into the slot 120 of the first cover 100 from bottom to top to form an upper positioning. Then, the lower part of the second cover 200 is snapped together with the lower part of the first cover 100 to form a lock. At this point, the first cover 100 and the second cover 200 enclose a complete installation space. During disassembly, it is only necessary to release the snap-lock between the lower part of the second cover 200 and the lower part of the first cover 100, and move the second cover 200 downwards (or move the first cover 100 upwards) to disengage the insertion part 220 from the slot 120. This allows for quick separation of the first cover 100 and the second cover 200 without the need for any tools. Compared with existing technologies, this embodiment eliminates the need to adjust tool angles within the narrow axial space of the motor mounting device. This embodiment significantly reduces operational complexity by operating on the front of the motor mounting device and utilizing the internal vertical space of the air conditioner for insertion and positioning, thus avoiding the axial space limitations of the motor mounting device. Furthermore, the insertion-clamping mechanical constraint mechanism ensures stable installation of the motor 300 while improving the assembly and disassembly efficiency of the motor mounting device, thereby significantly improving the maintenance efficiency of the motor 300.

[0048] like Figure 3 As shown, in some optional embodiments of this utility model, the lower part of the first cover 100 is provided with a buckle 130, and the lower part of the second cover 200 is provided with a snap-fit ​​groove 230 with the opening facing downward and engaging with the buckle 130.

[0049] In this embodiment, the assembly path and structural reliability are further optimized by the vertical engagement of the buckle 130 and the locking groove 230. Specifically, the locking groove 230 has its opening facing downwards, and during assembly, locking is achieved simply by automatically inserting the buckle 130 into the locking groove 230 in the vertical direction. The vertical engagement of the buckle 130 and the locking groove 230 creates a gravity self-locking effect, and when the motor 300 vibrates during operation, the weight of the second cover 200 can prevent the buckle 130 from disengaging. During disassembly, simply pressing down on the buckle 130 of the first cover 100 releases the engagement.

[0050] like Figure 6 As shown, in some optional embodiments of this utility model, the buckle 130 includes an elastic arm 131 and a buckle portion 132. The elastic arm 131 is disposed on the front side of the lower part of the first cover 100 and is horizontally positioned in its natural state. The elastic arm 131 is made of elastic material. The buckle portion 132 is disposed at the front end of the upper surface of the elastic arm 131 and is adapted to the snap-fit ​​groove 230. Correspondingly, the snap-fit ​​groove 230 is disposed on the front side of the lower part of the second cover 200, and the front side of the snap-fit ​​groove 230 has an opening. With the above arrangement, the buckle portion 132 can quickly separate from the snap-fit ​​groove 230 when the elastic arm 131 is pressed down.

[0051] In some alternative embodiments of this utility model, the lower part of the second cover is provided with a buckle, and the lower part of the first cover is provided with a snap-fit ​​groove with an opening facing downwards and engaging with the buckle. During assembly, the buckle on the second cover is pressed downwards, and then the insertion part of the second cover is inserted from bottom to top into the slot of the first cover to form an upper positioning. The buckle is then released, allowing it to automatically insert into the snap-fit ​​groove of the first cover, forming a lock. During disassembly, the buckle on the second cover is pressed downwards to disengage from the snap-fit ​​groove, and then the first cover is moved upwards to separate the second cover from the first cover.

[0052] like Figure 6 and Figure 7 As shown, in some optional embodiments of the present invention, the first cover 100 includes a first peripheral wall portion 111, a first end wall portion 112 and a second end wall portion 113 disposed opposite to each other at both ends of the first peripheral wall portion 111; the upper parts of the first end wall portion 112 and the second end wall portion 113 are both provided with slots 120, and the lower part of the second end wall portion 113 is provided with a buckle 130.

[0053] The second cover 200 includes a second peripheral wall portion 211, a third end wall portion 212 and a fourth end wall portion 213 disposed opposite to each other at both ends of the second peripheral wall portion 211; the upper part of the third end wall portion 212 and the fourth end wall portion 213 are both formed with insertion portions 220, and the lower part of the fourth end wall portion 213 is provided with a snap-fit ​​groove 230.

[0054] This embodiment achieves double-sided insertion guidance by symmetrically setting slots 120 at the upper part of both ends of the first cover 100 and correspondingly setting insertion parts 220 at both ends of the second cover 200, ensuring the accurate alignment and uniform force distribution of the first cover 100 and the second cover 200. Simultaneously, the lower locking structure (buckle 130 and locking groove 230) is centrally arranged on the second end wall 113 and the fourth end wall 213, forming a single-sided locking and double-sided constraint assembly logic. This embodiment simplifies disassembly to a single-point unlocking operation while ensuring structural stability; the first cover 100 and the second cover 200 can be separated vertically, avoiding the tediousness of operating multiple locking points one by one. Furthermore, the combination of double-sided insertion and single-sided locking compensates for axial deviation during motor 300 installation, reduces reliance on cover machining accuracy, improves overall structural reliability, and reduces the number of parts, achieving cost reduction and efficiency improvement.

[0055] In some alternative embodiments of this utility model, the lower parts of both the first and second end walls are provided with snap-fit ​​fasteners. Furthermore, the lower parts of the third and fourth end walls are provided with snap-fit ​​grooves. Compared to the previous embodiment, the two snap-fit ​​structures further improve the installation stability of the motor mounting device; however, compared to a single snap-fit ​​structure, it is less convenient for the installation and disassembly of the motor mounting device.

[0056] In some alternative embodiments of this utility model, a buckle is provided at the lower part of the first end wall, and a snap-fit ​​groove is provided at the lower part of the third end wall.

[0057] like Figure 5 As shown, in some optional embodiments of this utility model, a first damping ring 400 and a second damping ring 500 are respectively provided at both ends of the motor 300. The motor 300 is installed in the installation space through the first damping ring 400 and the second damping ring 500, and the cavity wall of the installation space is spaced apart from the motor 300. That is to say, the motor mounting device is in contact with the first damping ring 400 and the second damping ring 500 at both ends of the motor 300.

[0058] This embodiment uses a first damping ring 400 and a second damping ring 500 at both ends of the motor 300, and suspends the motor 300 within the installation space via these rings. This creates a gap between the motor 300 and the cavity wall of the installation space, forming a dual vibration isolation mechanism. The first damping ring 400 and the second damping ring 500 directly absorb high-frequency vibrations from the motor 300, while the cavity wall gap blocks low-frequency vibrations from being transmitted to the indoor unit's frame 600 and housing through rigid contact, reducing noise and preventing shaft wear caused by resonance, thus extending the motor 300's lifespan.

[0059] In some optional embodiments of this utility model, a first receiving groove with a forward opening is provided on the first end wall portion 112, and a second receiving groove with a rearward opening is provided on the third end wall portion 212. The first damping ring 400 is installed in the first and second receiving grooves. A third receiving groove with a forward opening is provided on the second end wall portion 113, and a fourth receiving groove with a rearward opening is provided on the fourth end wall portion 213. The second damping ring 500 is installed in the third and fourth receiving grooves.

[0060] In this embodiment, by providing receiving grooves with opposite opening directions on the end walls of the first cover 100 and the second cover 200, the first damping ring 400 and the second damping ring 500 can be precisely embedded into the corresponding receiving grooves, forming a multi-directional limiting structure. This design completely encloses the damping rings in the corresponding receiving grooves of the first cover 100 and the second cover 200, which not only prevents the damping rings from axially shifting or falling off due to vibration, but also evenly disperses vibration energy through the groove walls, further improving the noise reduction effect.

[0061] like Figure 6 As shown, in some optional embodiments of this utility model, a first end face 1121 is provided on the first end wall portion 112, and a second end face 2121 is provided on the third end wall portion 212. The first end face 1121 and the second end face 2121 are used to abut against the end face of the first damping ring 400 away from the motor 300. A third end face 1131 is provided on the second end wall portion 113, and a fourth end face 2131 is provided on the fourth end wall portion 213. The third end face 1131 and the fourth end face 2131 are used to abut against the end face of the second damping ring 500 away from the motor 300.

[0062] In this embodiment, the first cover 100 and the second cover 200 abut against the peripheral walls and at least part of the ends of the first damping ring 400 and the second damping ring 500. On the one hand, compared to the embodiment where the first cover 100 and the second cover 200 only contact the peripheral walls of the first damping ring 400 and the second damping ring 500, this embodiment increases the abutment contact between the first cover 100 and the second cover 200 and the ends of the first damping ring 400 and the second damping ring 500, thereby increasing the contact area between the motor mounting device and the two damping rings and improving the installation stability of the motor mounting device.

[0063] On the other hand, in this embodiment, the first end face 1121, the second end face 2121, the third end face 1131, and the fourth end face 2131 respectively form bidirectional limiting on the end face of the first damping ring 400 and the end face of the second damping ring 500, which not only prevents the two damping rings from failing due to axial movement caused by vibration, but also uniformly transmits vibration energy and improves the damping stability.

[0064] like Figure 3 , Figure 6 and Figure 7 As shown, in some optional embodiments of this utility model, a protrusion 510 is formed on the peripheral wall of the second damping ring 500. The second end wall portion 113 has a first limiting surface 1132 that abuts against one side of the protrusion 510. The fourth end wall portion 213 has a second limiting surface 2132 that abuts against the other side of the protrusion 510.

[0065] In this embodiment, the protrusion 510 on the circumferential wall of the second damping ring 500 abuts against the first limiting surface 1132 and the second limiting surface 2132 in both directions, forming a rigid constraint on the circumferential rotation of the motor 300. This effectively prevents the motor 300 from axially rotating due to vibration or load changes. While ensuring the damping performance, it avoids the complex assembly problems of traditional anti-rotation structures (such as keyways or screw fixation), thus balancing stability and ease of disassembly and assembly.

[0066] In some optional embodiments of the present invention, the first end wall portion 112 and the third end wall portion 212 are connected by a first screw extending from front to back.

[0067] In some alternative embodiments of this utility model, the second end wall portion 113 and the fourth end wall portion 213 are connected by a second screw extending forward and backward.

[0068] In some optional embodiments of this utility model, the first end wall portion 112 and the third end wall portion 212 are connected by a first screw extending forward and backward. The second end wall portion 113 and the fourth end wall portion 213 are connected by a second screw extending forward and backward.

[0069] Specifically, such as Figures 4 to 7 As shown, the first end wall 112 is provided with a first threaded hole 1122, the second end wall 113 is provided with a second threaded hole 1133, the third end wall 212 is provided with a third threaded hole 2122 corresponding to the first thread, and the fourth end wall 213 is provided with a fourth threaded hole 2133 corresponding to the second threaded hole 1133. The first thread and the third threaded hole 2122 are coaxially arranged, and the second threaded hole 1133 and the fourth threaded hole 2133 are coaxially arranged.

[0070] During assembly, the upper parts of the first cover 100 and the second cover 200 are inserted together, and their lower parts are snapped together. Then, the first screw is passed through the third threaded hole 2122 and into the first threaded hole 1122, achieving a threaded connection between the first screw and the first end wall 112 and the third end wall. Similarly, the second screw is passed through the fourth threaded hole 2133 and into the second threaded hole 1133, achieving a threaded connection between the second screw and the second end wall 113 and the fourth end wall. During disassembly, the first and second screws are removed first, then the lower parts of the first cover 100 and the second cover 200 are separated, and finally the upper parts of the first cover 100 and the second cover 200 are separated.

[0071] This embodiment adds a first screw and a second screw between the first cover 100 and the second cover 200, providing dual protection for high vibration or high load conditions while retaining the quick disassembly and assembly characteristics of plug-in and snap-fit.

[0072] In some optional embodiments of this utility model, there are two first screws, which are spaced apart in the vertical direction. There are also two second screws, which are spaced apart in the vertical direction. Compared to using only one first screw and one second screw, this further improves the connection stability between the first cover 100 and the second cover 200.

[0073] In some optional embodiments of this utility model, a first guide slope 221 is formed at the upper end of the plug portion 220.

[0074] In some optional embodiments of this utility model, a second guide slope 121 is provided at the opening of the inner wall of the slot 120.

[0075] like Figure 8 As shown, in some optional embodiments of this utility model, a first guide slope 221 is formed at the upper end of the insertion part 220; a second guide slope 121 is provided at the opening of the inner wall of the slot 120. Specifically, the inclination angle of the first guide slope 221 relative to the vertical direction is α; the inclination angle of the second guide slope 121 relative to the vertical direction is β, where α is less than or equal to β. Preferably, α is 25 to 35°, and β is 30 to 50°.

[0076] In the three embodiments described above, a progressive guiding mechanism is formed during the assembly process of the insertion part 220 and the slot 120 by setting the first guide slope 221 and / or the second guide slope 121. When the insertion part 220 is inserted into the slot 120, the slope contact generates a guiding force, automatically correcting the horizontal misalignment between the covers. In other words, the slope contact transforms the instantaneous impact force of traditional vertical insertion into a staged sliding force, reducing frictional resistance and making the assembly feel smoother, especially suitable for one-handed operation in confined spaces.

[0077] like Figure 3 , Figure 6 and Figure 7 As shown, in some optional embodiments of this utility model, the outer wall of the first cover 100 is formed with a first connecting ear 140, and the first connecting ear 140 has a first mounting hole 141 extending vertically for detachable connection with the frame 600 of the air conditioner indoor unit. The outer wall of the second cover 200 is formed with a second connecting ear 240, and the second connecting ear 240 has a second mounting hole 241 extending vertically for detachable connection with the frame 600. A stop portion for the frame 600 to abut against is also formed on the first cover 100 below the first connecting ear 140.

[0078] Specifically, the frame 600 is provided with a third mounting hole and a fourth mounting hole. The third mounting hole is coaxially arranged with the first mounting hole 141, and the fourth mounting hole is coaxially arranged with the second mounting hole 241. By installing a third screw in the third mounting hole and the first mounting hole 141, and a fourth screw in the fourth mounting hole and the second mounting hole 241, the first cover 100 and the second cover 200 can be detachably connected to the frame 600.

[0079] like Figures 1 to 8 As shown, this utility model embodiment also provides an indoor unit 10 for an air conditioner, which includes a motor 300, a frame 600, a fan 800, and a motor mounting device as described in any of the above embodiments.
