[0035] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0036] The stator assembly 100 according to an embodiment of the present utility model will be described below with reference to the drawings.

[0037] As Figures 1-3 shown, the stator assembly 100 according to an embodiment of the present utility model includes: a body 1, a stator stop 2, mounting ears 3, and reinforcing bosses 4.

[0038] Specifically, the stator stop 2 is provided on the axial end face of the body 1 and extends along the circumferential direction of the body 1. The mounting ears 3 are provided on the outer peripheral wall of the stator stop 2 and are multiple and spaced along the circumferential direction of the stator stop 2. Among them, the mounting ears 3 are approximately fan-shaped. The mounting ears 3 can mount the stator assembly 100 at a fixed position, such as on the motor base 201 described below, so as to fix the stator assembly 100. The multiple mounting ears 3 are spaced along the circumferential direction of the stator stop 2, which can further ensure that the stator assembly 100 is fixed firmly and reliably.

[0039] In the related art, due to the limited thickness of the mounting ears in the axial direction of the stator assembly, that is, the structural strength of the mounting ears is limited, and there is no relevant structure on the stator assembly to improve the strength of the motor stator mounting ears, it is difficult to ensure the reliability during high-load operation of the motor. And during the transportation and drop test of the motor and the entire air conditioner, the motor stator mounting ears are prone to breakage, seriously affecting the reliability and safety of the motor operation.

[0040] The reinforcing bosses 4 are provided on the inner peripheral wall of the stator stop 2, and there are multiple reinforcing bosses 4 corresponding to the multiple mounting ears 3. The corresponding reinforcing bosses 4 and mounting ears 3 are arranged opposite to each other in the thickness direction of the stator stop 2. The multiple reinforcing bosses 4 are provided on the body 1, and the multiple reinforcing bosses are respectively arranged opposite to the multiple mounting ears 3 in the thickness direction of the stator stop 2, which can increase the structural strength of the stator assembly 100 at the mounting ears 3, thereby enhancing the structural strength of the mounting ears 3, avoiding breakage of the mounting ears 3, and ensuring the reliability and safety of the operation of the entire air conditioner and the motor assembly 200.

[0041] When the mounting ear 3 bears an external force in the radial direction of the main body 1, the reinforcing boss 4 effectively absorbs and disperses the impact force applied to the mounting ear 3, and the reinforcing boss 4 plays a supporting role for the mounting ear 3. Therefore, the reinforcing boss 4 can improve the impact resistance and structural strength of the mounting ear 3. Moreover, the reinforcing boss 4 can effectively reduce the transmission of the impact force to the main body 1 of the stator assembly 100, so the overall structural strength and impact resistance of the stator assembly 100 can be improved, preventing the mounting ear 3 from breaking during transportation or in a drop test, and ensuring the reliability and safety of the operation of the entire air conditioner and the motor assembly 200.

[0042] For the stator assembly 100 according to the embodiment of the present invention, by providing a plurality of reinforcing bosses 4 on the inner peripheral wall of the stator spigot 2, and the plurality of reinforcing bosses 4 are respectively arranged opposite to the plurality of mounting ears 3 in the thickness direction of the stator spigot 2, the structural strength of the stator spigot 2 where the mounting ears 3 are provided can be improved, thereby improving the structural strength of the mounting ears 3, and improving the overall structural strength and impact resistance of the mounting ears 3 and the stator assembly 100. It can prevent the mounting ears 3 of the entire air conditioner or the motor assembly 200 from being damaged during transportation or in a drop test, and ensure the reliability and safety of the operation of the entire air conditioner and the motor assembly 200.

[0043] In some embodiments of the present invention, such as Figure 1 and Figure 5 shown, the reinforcing boss 4 is connected to the axial end face of the main body 1. It can be understood that the reinforcing boss 4 is not only connected to the inner peripheral wall of the stator spigot 2, but also connected to the axial end face of the main body 1. The two surfaces of the reinforcing boss 4 are fixed, which can improve the fixing reliability of the reinforcing boss 4, thereby improving the impact resistance of the reinforcing boss 4, being beneficial to improving the structural strength of the mounting ear 3, avoiding damage to the entire air conditioner or the motor assembly 200 during transportation or in a drop test, and ensuring the reliability and safety of the operation of the entire air conditioner and the motor assembly 200.

[0044] In some embodiments of the present invention, such as Figure 1 and Figure 2 shown, the reinforcing boss 4 is a fan-shaped annular protrusion, the outer peripheral wall of the reinforcing boss 4 extends along the circumferential direction of the stator spigot 2, and the connecting surface of the mounting ear 3 and the outer peripheral wall of the stator spigot 2 also extends along the circumferential direction of the stator spigot 2, which can better strengthen the connection between the mounting ear 3 and the stator spigot 2, thereby better enhancing the structural strength of the mounting ear 3, avoiding the fracture of the mounting ear 3, and ensuring the reliability and safety of the operation of the air conditioner and the motor assembly 200.

[0045] In some embodiments of the present invention, such as Figure 1 and Figure 2As shown, the body 1 is provided with pin terminals 11, and at least part of the reinforcing bosses 4 are provided with notches 41 for avoiding the pin terminals 11. The reinforcing bosses 4 can also be set to be irregular in order to avoid the pin terminals 11. The pin terminals 11 are components that can quickly and reliably connect and disconnect the lead wires in the motor assembly 200, making the circuit connection in the motor assembly 200 more convenient. Therefore, the reinforcing bosses 4 can improve the impact resistance and structural strength of the mounting ears 3 and the stator assembly 100 as a whole without affecting the circuit connection in the motor assembly 200.

[0046] In some embodiments of the present invention, as Figure 2 and Figure 3 shown, there are three mounting ears 3 evenly spaced along the circumferential direction of the body 1, and there are also three reinforcing bosses 4 arranged opposite to the mounting ears 3. Thus, not only can the reliability of the stator assembly 100 fixed on the fixing device be ensured, but also the structure of the stator assembly 100 can be simplified, the production efficiency can be improved, the material usage of the stator assembly 100 can be reduced, and the production cost can be lowered.

[0047] In some embodiments of the present invention, as Figure 1 and Figure 5 shown, a fillet 5 is provided between the end face of the mounting ear 3 along the axial direction of the body 1 and the outer peripheral wall of the stator stop 2. Thus, the dimension of the connection surface between the mounting ear 3 and the stator stop 2 along the axial direction of the stator assembly 100 can be increased, ensuring the reliability of the connection between the mounting ear 3 and the stator stop 2. At the same time, the sharp corner stress concentration problem at the connection between the mounting ear 3 and the stator stop 2 can be improved, avoiding the mounting ear 3 from breaking due to stress, thereby ensuring the structural strength of the mounting ear 3, and further ensuring the reliability of the operation of the motor assembly 200 and the air conditioner. In some embodiments of the present invention, as Figure 1 and Figure 2 shown, fillets 5 are provided between the two end faces of the mounting ear 3 along the circumferential direction of the body 1 and the outer peripheral wall of the stator stop 2. Thus, the dimension of the connection surface between the mounting ear 3 and the stator stop 2 along the circumferential direction of the stator assembly 100 can be increased, ensuring the reliability of the connection between the mounting ear 3 and the stator stop 2. At the same time, the sharp corner stress concentration problem at the connection between the mounting ear 3 and the stator stop 2 can be improved, avoiding the mounting ear 3 from breaking due to stress, thereby ensuring the structural strength of the mounting ear 3, and further ensuring the reliability of the operation of the motor assembly 200 and the air conditioner.

[0048] In some embodiments of the present invention, as Figure 2 、 Figure 3 and Figure 5As shown, the dimension of the mounting ear 3 in the radial direction of the body 1 is T, and the radius of the rounded corner 5 is R, satisfying: 0.1T ≤ R ≤ 0.4T. If the radius R of the rounded corner 5 ≤ 0.1T, the structural strength at the position of the rounded corner 5 is weak. When the mounting ear 3 is subjected to an impact force in the radial direction, stress concentration occurs at the position of the rounded corner 5, and it cannot play a buffering role, and the mounting ear 3 is easily broken. If the radius R of the rounded corner 5 ≥ 0.4T, the radius of the rounded corner 5 is too large, which is not conducive to the assembly of the mounting ear 3 with other components (such as the shock-absorbing sleeve 202 described below). If the radius R of the rounded corner 5 satisfies 0.1T ≤ R ≤ 0.4T, it is possible to facilitate the assembly of the mounting ear 3 with other components while ensuring the structural strength at the position of the rounded corner 5.

[0049] In some embodiments of the present invention, as Figure 2 and Figure 3 shown, along the circumferential direction of the body 1, the width of the mounting ear 3 is L1, and the perimeter of the outer peripheral wall of the stator stop 2 is L2 (such as Figure 3 the perimeter at the position indicated by L2 in ), and it satisfies: 0.05L2 ≤ L1 ≤ 0.2L2. If the width of the mounting ear 3 is L1 ≤ 0.05L2, the structural strength of the mounting ear 3 is weak. When the mounting ear 3 is subjected to an impact force in the radial direction, the mounting ear 3 may be damaged, and the mounting ear 3 is too small to be easily installed with the components for installing the motor assembly 200. If the width of the mounting ear 3 is L1 ≥ 0.2L2, there is redundant material for the mounting ear 3. If the width of the mounting ear 3 is L1 and satisfies 0.05L2 ≤ L1 ≤ 0.2L2, it is possible to reduce the structural redundancy of the mounting ear 3 while ensuring the structural strength of the mounting ear 3.

[0050] Among them, along the circumferential direction of the body 1, the width L1 of the mounting ear 3 can be the minimum distance, the middle point distance, or the maximum distance between the two opposite wall surfaces of the mounting ear 3 along the circumferential direction of the body 1.

[0051] Next, refer to the attached Figure 4 to describe the motor assembly 200 according to the embodiments of the present invention.

The motor base 201 is formed in a ring shape, and a convex portion is provided on the inner peripheral wall of the motor base 201. An installation groove is provided on one side of the convex portion along the axial direction of the motor base 201, and the installation groove is open inward in the radial direction of the motor base 201. The stator assembly 100 is disposed in the motor base 201, and a mounting ear 3 is provided on the outer peripheral wall of the stator assembly 100, and the mounting ear 3 is located in the installation groove.

[0053] Specifically, a convex portion is provided on the inner peripheral wall of the motor base 201, and the structural strength of the motor base 201 can be improved through the convex portion. In addition, since the mounting ear 3 is located in the mounting groove, the mounting groove can support and position the mounting ear 3, thereby realizing the support and positioning of the stator assembly 100 in the motor base 201, achieving the axial positioning and circumferential positioning of the stator assembly 100, avoiding problems such as displacement of the stator assembly 100 on the motor base 201, ensuring reliable limiting of the stator assembly 100 in the motor base 201, and the structure of the mounting groove is simple and convenient for processing and manufacturing.
