The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0042] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0043] The following reference Figures 1 to 4 This describes the motor assembly 100 of the second aspect embodiment of the present invention and the bracket 102 of the first aspect embodiment of the present invention.

[0044] Reference Figure 1As shown, the motor assembly 100 of the second aspect embodiment of the present invention includes a motor 101 and a bracket 102. Two mounting bosses 103 are respectively provided on opposite sides of the motor 101. The bracket 102 includes a base 104, two retaining rings 105, and a surrounding plate 106. The base 104 has two recesses 201 for supporting the mounting bosses 103 of the motor 101. The retaining rings 105 are connected to the base 104, and the retaining rings 105 and the recesses 201 define mounting holes 202 for mounting the mounting bosses 103 of the motor 101. The surrounding plate 106 is connected to the base 104 and includes two first limiting portions 107. The two first limiting portions 107 limit the displacement of the retaining rings 105 along the axial direction of the mounting holes 202, i.e., the two first limiting portions 107 prevent the retaining rings 105 from moving in the left-right direction.

[0045] Traditional solutions use four retaining rings 105 to fix the motor 101 to the base 104. The retaining rings 105 serve two functions: first, to prevent the motor 101 from moving laterally; and second, to prevent the motor 101 from moving vertically. Therefore, the retaining rings 105 need to be pulled very tight, requiring two retaining rings 105 on each side to restrain the motor 101. In this embodiment, fixing the motor 101 to the base 104 with two retaining rings 105 prevents the motor 101 from moving vertically. The surrounding plate 106, located outside the retaining rings 105, limits the lateral movement of the retaining rings 105, preventing them from moving laterally, and also preventing the motor 101 from moving laterally. The bracket 102 of this embodiment, through the cooperation of the two retaining rings 105 and the surrounding plate 106 with the base 104, limits the vertical and horizontal displacement of the motor 101, reducing the number of retaining rings 105, thereby improving installation and disassembly efficiency and facilitating installation and maintenance.

[0046] In some embodiments, the enclosure 106 further includes a second limiting portion 108, which abuts against the motor 101 to prevent the motor 101 from moving in the left-right direction. The second limiting portion 108 extends from the first limiting portion 107 toward the motor 101, so that the second limiting portion 108 can directly contact the motor 101 and directly limit the motor 101.

[0047] Reference Figure 1 As shown, in some embodiments, the enclosure 106 is U-shaped, with two first limiting portions 107 located at both ends of the enclosure 106. The U-shaped enclosure 106 can wrap the retaining ring 105 inside, preventing the retaining ring 105 from moving in the left and right directions, while also forming a handle-like function, providing a force application point, and facilitating the operator to move the motor assembly 100.

[0048] Reference Figure 2As shown, in some embodiments, the end of the retaining ring 105 facing the first limiting part 107 is provided with a flange 203 that bends toward the mounting hole 202, which can increase the strength of the retaining ring 105 and limit the sealing ring (not shown in the figure) mounted on the mounting boss 103, limiting the displacement of the sealing ring in the axial direction of the mounting hole 202, and improving the working reliability of the motor 101.

[0049] Reference Figure 2 As shown, in some embodiments, one end of the retaining ring 105 is connected to the base 104 via a first fastener (not shown in the figure), and the other end of the retaining ring 105 is engaged with the base 104. This simplifies the assembly between the retaining ring 105 and the base 104, requires fewer parts, and improves assembly efficiency. It should be noted that the first fastener includes, but is not limited to, screws; for example, it can also be a rivet, pin, etc.

[0050] In some more specific embodiments, the base 104 is provided with a spaced-apart first connecting portion 204 and a hook portion 205, and the two ends of the retaining ring 105 are respectively provided with a second connecting portion 206 and a locking hole portion 207. The first connecting portion 204 and the second connecting portion 206 are connected by a first fastener, and the hook portion 205 engages with the locking hole portion 207, thereby realizing the assembly of the retaining ring 105 and the base 104. It can be understood that the retaining ring 105 engaging with the base 104 can also be achieved by providing a locking hole portion 207 on the base 104, and a corresponding hook portion 205 at one end of the retaining ring 105.

[0051] Reference Figure 1 and Figure 2 As shown, in some embodiments, the first connecting portion 204 and the hook portion 205 are disposed on opposite sides of the mounting hole 202. The first connecting portion 204 is provided with a first through hole 208 for the first fastener to pass through. The second connecting portion 206 and the locking hole portion 207 are disposed at both ends of the retaining ring 105. The second connecting portion 206 is provided with a second through hole 209 for the first fastener to pass through. During assembly, the motor 101 can be placed on the base 104, with the mounting boss 103 of the motor 101 mounted on the recess 201 of the base 104. The locking hole portion 207 of the retaining ring 105 is passed through the hook portion 205 of the base 104. The first through hole 208 of the first connecting portion 204 is aligned with the second through hole 209 of the second connecting portion 206. The first fastener passes through the second through hole 209 and the first through hole 208, connecting the second connecting portion 206 and the first connecting portion 204 together.

[0052] Reference Figure 1As shown, in some embodiments, the enclosure 106 is provided with a third connecting portion 109, and the first connecting portion 204, the second connecting portion 206, and the third connecting portion 109 are connected by a first fastener. Specifically, the third connecting portion 109 is provided with a third through hole (not shown in the figure) for the first fastener to pass through. During the assembly process, the first fastener passes through the second through hole 209, the third through hole, and the first through hole 208, connecting the second connecting portion 206, the third connecting portion 109, and the first connecting portion 204 together. That is, the first fastener connects the retaining ring 105, the enclosure 106, and the base 104 together at one time, which makes the assembly between the retaining ring 105, the enclosure 106, and the base 104 simpler, requires fewer parts, and improves assembly efficiency.

[0053] Reference Figure 1 and Figure 2 As shown, in some embodiments, the retaining ring 105 is provided with reinforcing ribs 210 extending along the length direction of the retaining ring 105, which can increase the overall strength of the retaining ring 105.

[0054] Reference Figure 3 and Figure 4 As shown, in some embodiments, the recess 201 is provided with a limiting protrusion 211. The limiting protrusion 211 is used to limit the displacement of the motor 101 along the axial direction of the mounting hole 202, that is, the limiting protrusion 211 blocks the displacement of the mounting boss 103 of the motor 101 in the axial direction of the mounting hole 202. The limiting protrusion 211 on the base 104 cooperates with the surrounding plate 106 to jointly limit the displacement of the motor 101 along the axial direction of the mounting hole 202, enhance the limiting effect, effectively ensure that the motor 101 can work stably, and improve the reliability of the operation.

[0055] Reference Figure 3 As shown, in some embodiments, the base 104 includes a rear plate 301 and two side plates 302, which are respectively connected to opposite sides of the rear plate 301. The rear plate 301 and the two side plates 302 define a space for housing the motor 101. Each side plate 302 has a recess 201. (Refer to...) Figure 2 As shown, two retaining rings 105 are respectively connected to two side plates 302. The retaining rings 105 are connected to the side plates 302 to define the mounting holes 202 for accommodating the mounting boss 103 of the motor 101.

[0056] Therefore, referring to Figure 1 As shown, the motor 101 is placed between the two side plates 302, and the mounting boss 103 of the motor 101 is confined within the mounting hole 202. It should be noted that the motor 101 can be a single-output shaft motor 101 or a dual-output shaft motor 101. The output shaft is set on the mounting boss 103, and the output shaft passes through the mounting hole 202 to cooperate with other parts, such as a fan.

[0057] Reference Figure 5 As shown, the air conditioner according to a third aspect embodiment of the present invention includes a motor assembly 100, a chassis 501, a volute 502, an air inlet grille 503, a crossbeam 504, a drip tray 505, an evaporator 506, etc., as described in the second aspect embodiment of the present invention. The crossbeam 504 is located in the middle of the chassis 501, and the bracket 102 is connected to both the crossbeam 504 and the chassis 501 to fix the motor 101. This embodiment of the air conditioner, by employing the motor assembly 100 of the second aspect embodiment of the present invention, reduces the number of retaining rings 105, thereby improving the efficiency of installation and disassembly, and facilitating installation and maintenance.

[0058] In some embodiments, a first limiting structure is provided between the base 104 and the crossbeam 504, and a second limiting structure is provided between the base 104 and the chassis 501. The first and second limiting structures are used to limit the bracket 102 during installation, preventing it from moving and facilitating installation. Simultaneously, the first limiting structure can also increase the connection strength between the base 104 and the crossbeam 504, and the second limiting structure can also increase the connection strength between the base 104 and the chassis 501.

[0059] In some embodiments, the first limiting structure includes a first hook 303 and a first hanging hole 801. (Refer to...) Figure 3 , Figure 7 and Figure 8 As shown, the back plate 301 of the base 104 is provided with a first hook 303, and the crossbeam 504 is provided with a first hanging hole 801. The first hook 303 passes through the first hanging hole 801 from top to bottom and is hung on the crossbeam 504, thereby limiting the position of the base 104 and the crossbeam 504 and increasing the connection strength between the base 104 and the crossbeam 504, preventing the bracket 102 from detaching from the crossbeam 504.

[0060] It should be noted that the first hook 303 can also be set on the crossbeam 504, and correspondingly, the first hanging hole 801 is set on the back plate 301 of the base 104.

[0061] In some embodiments, the second limiting structure includes a second hook 304 and a second hanging hole 601. (Refer to...) Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown, the side plate 302 of the base 104 is provided with a second hook 304. The second hook 304 is located at one end of the side plate 302 near the crossbeam 504. The chassis 501 is provided with a second hanging hole 601. The second hook 304 passes through the second hanging hole 601 from front to back and is hooked on the chassis 501, thereby limiting the position of the base 104 and the chassis 501 and increasing the connection strength between the base 104 and the chassis 501, preventing the bracket 102 from detaching from the chassis 501.

[0062] It should be noted that the second hook 304 can also be set on the chassis 501. Correspondingly, the second hanging hole 601 is set on the rear plate 301 or side plate 302 of the base 104.

[0063] In some embodiments, the base 104 and the crossbeam 504 are connected by a second fastener (not shown in the figure), which further improves the connection strength and reliability, eliminates the need for welding, facilitates disassembly and assembly, and ensures that the motor 101 operates more stably and is less prone to shaking.

[0064] In some embodiments, the base 104 is connected to the chassis 501 by a third fastener (not shown in the figure), which further improves the connection strength and reliability, eliminates the need for welding, facilitates disassembly and assembly, and ensures that the motor 101 operates more stably and is less prone to shaking.

[0065] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
