[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] like Figures 1 to 3 as well as Figures 8 to 11 As shown, an embodiment of the utility model provides a motor assembly, which includes a motor body 10, a first shock absorbing part 20 and a second shock absorbing part 30. The motor body 10 includes a housing 11 and an ear seat 12, and the ear seat 12 is arranged on the side wall of the housing 11. The first shock absorbing part 20 is arranged at the bottom of the housing 11, and the first shock absorbing part 20 is used to abut against the mounting frame 60. The second shock absorbing part 30 is arranged on the ear seat 12, and the second shock absorbing part 30 is used to connect with the mounting frame 60. The second shock absorbing part 30 includes a shock absorbing end, which is located on the end surface of one end of the ear seat 12, and the shock absorbing end is used to abut against the mounting frame 60.

[0050] By applying the technical solution of the utility model, the first shock absorbing part 20 is arranged at the bottom of the housing 11, and is used to abut against the mounting frame 60, and the second shock absorbing part 30 is arranged on the ear seat 12, and is used to abut against the mounting frame 60. Such a setting can achieve double shock absorption of the motor body 10, and improve the shock absorption and buffering effect of the motor body 10. In the traditional technical solution, the bottom of the motor body and the ear seat are rigidly in contact with the mounting frame respectively, and the vibration amplitude is large during the operation of the motor, which is easy to generate noise. And after the motor assembly is assembled into a complete machine, when the complete machine falls, the ear seat may break. Compared with the traditional technical solution, the setting of this solution enables flexible contact between the bottom of the motor body 10 and the mounting frame 60, and flexible contact between the ear seat 12 of the motor body 10 and the mounting frame 60, which improves the buffering effect of the motor body 10, reduces the noise generated during the operation of the motor assembly, and also reduces the situation that the ear seat 12 breaks when the complete machine falls.

[0051] This solution does not limit the specific form of the housing 11. The first shock absorbing part 20 is designed according to the bottom shape of the housing 11.

[0052] like Figure 1 As shown, in some embodiments of the present scheme, the shell 11 includes a main body 111 and a base 112, the base 112 is arranged at the bottom end of the main body 111, and the base 112 is coaxial with the main body 111, and the projection of the base 112 along the axial direction is located on the main body 111.

[0053] In some embodiments of the present solution, the first shock absorbing part 20 is disposed at the bottom of the base 112. The specific connection method between the first shock absorbing part 20 and the base 112 is not limited. The two can be connected by means of a clamping connection, a connector, etc.

[0054] In other embodiments of the present invention, the first shock absorbing part 20 is disposed on the side of the base 112. In this case, the first shock absorbing part 20 may be sleeved on the base 112. Alternatively, a plurality of first shock absorbing parts 20 are provided, and the plurality of first shock absorbing parts 20 are distributed on the side wall of the base 112 at intervals along the circumference of the base 112.

[0055] In this embodiment, the first shock absorbing part 20 includes a shock absorbing sleeve, and the shock absorbing sleeve is arranged on the base 112. Such an arrangement has a simple structure and is convenient for connecting the two.

[0056] like Figure 1 and Figure 4 As shown, specifically, the shock-absorbing sleeve includes a blocking end and an open end that are arranged opposite to each other, and the open end of the shock-absorbing sleeve is provided with a flange structure 201, which is arranged in an annular manner on the outside of the shock-absorbing sleeve, and the flange structure 201 is abutted against the bottom end surface of the main body 111. Such an arrangement can increase the contact area between the shock-absorbing sleeve and the main body 111, increase the friction between the shock-absorbing sleeve and the main body 111, and ensure the stability of the connection between the shock-absorbing sleeve and the base 112.

[0057] Furthermore, the shock-absorbing sleeve is interference-fitted with the base 112. Such an arrangement can further ensure the stability of the connection between the shock-absorbing sleeve and the base 112.

[0058] This solution does not limit the specific connection form between the second shock absorbing part 30 and the mounting bracket 60.

[0059] like Figures 1 to 3 as well as Figure 5 and Figure 6 As shown, in some embodiments of the present solution, the second shock absorbing part 30 is provided with an assembly hole 301, and the assembly hole 301 is arranged along the axis direction of the housing 11 and penetrates the second shock absorbing part 30. Such an arrangement facilitates the connection between the second shock absorbing part 30 and the mounting frame 60 by matching the connecting member with the assembly hole 301.

[0060] Furthermore, the motor assembly further includes an insert 40, at least a portion of which is inserted into the assembly hole 301, and the insert 40 is provided with a connecting hole 401, which is provided through the insert 40 along the axis direction of the assembly hole 301. The provision of the insert 40 can prevent the connecting member from directly contacting the second damping part 30, thereby reducing the wear of the connecting member on the assembly hole 301 and improving the service life of the second damping part 30.

[0061] Specifically, the insert 40 includes a penetration section 41 and a stop section 42 connected in a stepped manner along the axial direction, the penetration section 41 is penetrated in the assembly hole 301, and the stop section 42 is abutted against the end surface of the second damping part 30. Such a configuration facilitates the stability of the connection between the insert 40 and the second damping part 30.

[0062] In this embodiment, the length of the penetration section 41 is smaller than the axial dimension of the assembly hole 301. This arrangement facilitates the second shock absorbing part 30 to deform after being compressed, thereby improving the shock absorbing effect of the second shock absorbing part 30.

[0063] In this embodiment, the stopper section 42 is annularly arranged on the outer periphery of one end of the penetration section 41, and the penetration section 41 and the stopper section 42 are integrally formed. Such an arrangement can improve the stability of the connection between the stopper section 42 and the penetration section 41, and ensure the miniaturization of the insert 40 in the axial direction.

[0064] This solution does not limit the specific number and form of the ear seats 12.

[0065] In some embodiments of the present solution, one ear seat 12 is provided, and the ear seat 12 is annularly arranged on the side wall of the shell 11 along the circumference of the shell 11 .

[0066] In some other embodiments of the present solution, a plurality of ear seats 12 are provided, and the plurality of ear seats 12 are arranged on the side wall of the shell 11 at intervals along the circumference of the shell 11 .

[0067] In this embodiment, three ear seats 12 are provided.

[0068] This solution does not limit the specific connection method between the second shock absorbing part 30 and the ear seat 12.

[0069] In this embodiment, the second shock absorbing part 30 is clamped with the ear seat 12. Such a configuration can avoid the situation where a rigid connection occurs between the second shock absorbing part 30 and the ear seat 12, and further improve the shock absorbing effect of the second shock absorbing part 30 on the ear seat 12.

[0070] like Figures 1 to 3 Specifically, the ear seat 12 is provided with a snap-in hole 121 and an opening 122, the snap-in hole 121 is provided along the axial direction of the housing 11 through the ear seat 12, the opening 122 is provided on the side wall of the snap-in hole 121, the second shock absorbing part 30 is provided through the opening 122 into the snap-in hole 121, and the second shock absorbing part 30 is snap-fitted with the ear seat 12 through the snap-in hole 121. The provision of the snap-in hole 121 and the opening 122 has a simple structure and facilitates the assembly of the second shock absorbing part 30 and the ear seat 12.

[0071] In this embodiment, the ear seat 12 has an upper end surface and a lower end surface that are arranged opposite to each other, and the lower end surface is arranged close to the base 112 .

[0072] Further, the second shock absorbing part 30 includes a clamping section and a shock absorbing section 32 arranged in sequence along the axial direction of the shell 11, the clamping section is clamped with the clamping hole 121, the projection of the clamping section in the axial direction is located in the shock absorbing section 32, the shock absorbing section 32 is located at one end of the ear seat 12 close to the bottom of the shell 11, and is abutted with the ear seat 12. In this embodiment, the shock absorbing section 32 is generally a sheet structure, and the projection of the ear seat 12 in the axial direction of the shell 11 is located in the shock absorbing section 32. Such an arrangement can ensure the contact area between the shock absorbing section 32 and the mounting bracket 60 as much as possible. And the shock absorbing section 32 is relatively flat, so such an arrangement can further improve the stability of its contact with the mounting bracket 60 and the ear seat 12.

[0073] This solution does not limit the specific clamping form between the clamping section and the clamping hole 121.

[0074] like Figure 3 , Figures 5 to 7 As shown, in this embodiment, the snap-in hole 121 includes a first hole section 1211 and a second hole section 1212 connected in sequence along the axial direction of the housing 11, the second hole section 1212 is located below the first hole section 1211, the cross-sectional area of ​​the second hole section 1212 is smaller than the cross-sectional area of ​​the first hole section 1211, and a first snap-in surface is formed between the second hole section 1212 and the first hole section 1211; the snap-in section includes a first snap-in section 311 and a second snap-in section 312 connected in sequence along the direction from the first hole section 1211 to the second hole section 1212, the second snap-in section 312 is connected to the damping section 32, the cross-sectional area of ​​the second snap-in section 312 is smaller than the cross-sectional area of ​​the first snap-in section 311, and a second snap-in surface is formed between the second snap-in section 312 and the first snap-in section 311, and the second snap-in surface is snap-fitted with the first snap-in surface. The above arrangement has a simple structure and is convenient for realizing the snap-fitting of the second damping part 30 with the snap-in section.

[0075] Furthermore, at least one of the first hole section 1211 and the second hole section 1212 is constricted near the opening 122. This arrangement can ensure the stability of the clamping between the clamping section and the ear seat 12 and reduce the separation of the second damping part 30 from the ear seat 12.

[0076] like Figures 8 to 11 As shown, the embodiment of the utility model also provides an air conditioner, which includes a volute 50, a mounting bracket 60, a fastener 70 and the motor assembly in the above embodiment. The volute 50 is provided with a mounting opening 501. The mounting bracket 60 is arranged at the mounting opening 501. The first damping part 20 of the motor assembly abuts against the mounting bracket 60, the damping end of the second damping part 30 of the motor assembly abuts against the mounting bracket 60, and the second damping part 30 is connected to the mounting bracket 60 through the fastener 70.

[0077] In this embodiment, the mounting frame 60 includes a main body 61 and a leg 62. The main body 61 is generally a circular plate-shaped structure, and the main body 61 is arranged corresponding to the base 112. There are three legs 62, which are arranged at intervals along the circumference of the main body 61 on the side of the main body 61. The legs 62 are arranged one by one with the ear seats 12, and one end of the leg 62 away from the main body 61 is arranged on the side wall of the mounting opening 501. Such an arrangement can ensure that the mounting frame 60 occupies as little space as possible in the mounting opening 501, improve the ventilation effect, and ensure the stability of the installation of the mounting frame 60 and the volute 50 as much as possible.
