The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0045] Hereinafter, a motor assembly 1 according to an embodiment of the first aspect of the present utility model will be described with reference to the accompanying drawings.

[0046] like Figure 1 , Figure 5 and Fig. 9 As shown, the motor assembly 1 includes a motor 11, and the motor 11 includes a main body 111 and a plurality of mounting groups 112 arranged on the outer peripheral wall of the main body 111. The plurality of mounting groups 112 are sequentially arranged along the circumference of the motor 11, and each mounting group 112 includes two first mounting parts 1121 arranged opposite to each other along the radial direction of the motor 11. The motor 11 can be installed through the plurality of first mounting parts 1121. It can be understood that the plurality of mounting groups 112 can be arranged at intervals along the circumference of the motor 11, or can be arranged in connection with each other.

[0047] For example, Figure 1 , Figure 5 and Fig. 9 As shown, the motor 11 includes two installation groups 112, the two installation groups 112 are respectively a first installation group 112 and a second installation group 112, the two first installation parts 1121 of the first installation group 112 are arranged oppositely along the first radial direction, and the two second installation parts 1211 of the second installation group 112 are arranged oppositely along the second radial direction, and the second radial direction intersects with the first radial direction, then the first installation group 112 can limit the movement of the motor 11 in the first radial direction, and the second installation group 112 can limit the movement of the motor 11 in the second radial direction, so as to facilitate the limitation of the position of the motor 11 on the radial plane; further, the second radial direction is perpendicular to the first radial direction. Of course, in other examples, the motor 11 can also include three or more installation groups 112.

[0048] Among them, the motor 11 is a DC motor. Compared with the solution of using an AC motor, the AC motor is easy to generate harmonic noise under different voltages, which makes the running noise of the AC motor larger, and the cost of the AC motor is relatively high. The above-mentioned setting of the present application is conducive to improving the running noise caused by the type of the motor 11 itself, thereby facilitating the reduction of the overall noise of the motor 11, and the cost of the DC motor is relatively low. It can be understood that the type of the DC motor is not specifically limited in the embodiment of the present application, and it is only necessary to realize the conversion of DC power and mechanical energy.

[0049] like Figure 1 and Figure 4 As shown, the motor assembly 1 also includes a bracket 12, which is sleeved on the outside of the motor 11, and the bracket 12 is located on one axial side of the first mounting portion 1121, that is, the bracket 12 is located on one side of the first mounting portion 1121 in the axial direction of the motor 11, and a plurality of second mounting portions 1211a corresponding to the plurality of first mounting portions 1121 are formed on the bracket 12, and the plurality of second mounting portions 1211a are also arranged in sequence along the circumference of the motor 11, and each first mounting portion 1121 can cooperate with the corresponding second mounting portion 1211a to facilitate the installation of the motor 11.

[0050] like Figure 5 As shown, the motor assembly 1 also includes a vibration damper 13 and a first fastener 14. The vibration damper 13 wraps at least a portion of the first mounting portion 1121 so that the vibration damper 13 is suitable for axially limiting cooperation with the first mounting portion 1121 along the motor 11. The first fastener 14 is penetrated by the vibration damper 13 and the corresponding second mounting portion 1211a. For example, the first fastener 14 is penetrated by the vibration damper 13 and the corresponding second mounting portion 1211a along the axial direction of the motor 11 so that the connection between the first mounting portion 1121 and the corresponding second mounting portion 1211a is achieved through the vibration damper 13. Then, the first fastener 14 and the first mounting portion 1121 are also separated by the vibration damper 13, which is beneficial to reduce the vibration energy of the first mounting portion 1121 transmitted to the second mounting portion 1211a through the first fastener 14. It can be seen that each first mounting portion 1121 corresponds to a vibration damper 13 and a second mounting portion 1211a respectively; the motor 11 is provided with multiple mounting groups 112, and the assembly of the vibration damper 13 and the first fastener 14 is coordinated to facilitate the reliable limitation and installation of the motor 11 in the axial, radial and circumferential directions.

[0051] Among them, a part of the vibration damping member 13 is sandwiched between the first mounting portion 1121 and the second mounting portion 1211a, and the above-mentioned part of the vibration damping member 13 separates the first mounting portion 1121 and the second mounting portion 1211a so as to achieve elastic contact between the first mounting portion 1121 and the second mounting portion 1211a. The vibration damping member 13 can absorb the vibration energy of the motor 11 to a certain extent. For example, the vibration damping member 13 can absorb the axial vibration energy of the motor 11 to reduce the transmission of the vibration energy along the axial direction of the motor 11, which is beneficial to buffering the vibration transmitted from the first mounting portion 1121 to the second mounting portion 1211a, thereby helping to reduce the vibration noise of the motor assembly 1 and improve the product sound quality.

[0052] It should be noted that the vibration damper 13 is suitable for axially limiting cooperation with the first mounting portion 1121 along the motor 11, and may include at least one of the following situations: 1. In the absence of other external forces, the vibration damper 13 and the first mounting portion 1121 can cooperate to achieve axial limiting cooperation between the two in the motor 11; 2. The vibration damper 13 undergoes a certain deformation under the pressure applied by the first fastener 14, so that the vibration damper 13 and the first mounting portion 1121 are axially limited.

[0053] According to the motor assembly 1 of the embodiment of the utility model, through multiple first mounting parts 1121, the vibration damping member 13 wraps at least part of the first mounting part 1121, so that the vibration damping member 13 is suitable for the first mounting part 1121 along the axial limit cooperation of the motor 11, and a part of the vibration damping member 13 is clamped between the first mounting part 1121 and the second mounting part 1211a, and the first fastener 14 is passed through the vibration damping member 13 and the corresponding second mounting part 1211a, which is convenient for realizing the reliable installation of the motor 11, and at the same time realizes the separation setting of the first mounting part 1121 and the first fastener 14, and the separation setting of the first mounting part 1121 and the second mounting part 1211a, which is beneficial to reduce the vibration noise of the motor assembly 1 and improve the sound quality of the product. At the same time, the structure is simple, and both the above-mentioned vibration reduction cost and the cost of the motor 11 are low.

[0054] In addition, when the motor assembly 1 is used in the air conditioner 100, it is beneficial to improve the sound quality of the air conditioner 100 to a certain extent, and it is convenient to reduce the cost of the air conditioner 100; wherein, the type of the above-mentioned air conditioner 100 is not specifically limited in this application, for example, the air conditioner 100 can be a split air conditioner or an integrated air conditioner, the air conditioner 100 can be a wall-mounted air conditioner, a cabinet air conditioner (such as a square cabinet air conditioner, or a round cabinet air conditioner, etc.), a window air conditioner, or a mobile air conditioner, etc. Of course, the motor assembly 1 of the embodiment of the present application is not limited to being used in the air conditioner 100, for example, the motor assembly 1 can also be used in a humidifier, a dehumidifier, or an air purifier, etc.

[0055] It should be noted that, in the embodiment of the present application, the main body 111 may include a motor shaft 1111, the axial direction of the motor 11 is the extension direction of the central axis L of the motor 11, the central axis L of the motor 11 is the central axis of the motor shaft 1111, the circumferential direction of the motor 11 is the direction around the central axis L of the motor 11, the radial direction of the motor 11 is the direction passing through the central axis L of the motor 11 in the radial plane, and the radial plane is perpendicular to the central axis L of the motor 11; it can be seen that the circumferential, axial and radial directions of the motor 11 are perpendicular to each other.

[0056] In some embodiments, Figure 5 As shown, the first mounting portion 1121 includes a first part 1121a, and the first part 1121a is formed with a mounting groove 1121b, which penetrates the first part 1121a axially, and the first slot 1121c of the mounting groove 1121b is formed on the outer side wall of the first part 1121a. The outer side wall of the first part 1121a can be understood as the side wall of the first part 1121a that is away from the central axis L of the motor 11. The vibration damper 13 includes a first vibration damper portion 131, a second vibration damper portion 132 and a third vibration damper portion 133. The first vibration damper portion 131 is clamped in the mounting groove 1121b through the first notch 1121c, and the first vibration damper portion 131 is formed with a through hole 131a for penetrating the first fastener 14. The second vibration damper portion 132 and the third vibration damper portion 133 are respectively arranged at two axial ends of the first vibration damper portion 131. The first part 1121a is sandwiched between the second vibration damper portion 132 and the third vibration damper portion 133 to achieve the limited cooperation between the vibration damper 13 and the first mounting portion 1121 in the axial direction of the motor 11. The third vibration damper portion 133 is sandwiched between the first mounting portion 1121 and the second mounting portion 1211a to separate the first mounting portion 1121 and the second mounting portion 1211a.

[0057] It can be seen that in the above scheme, when the vibration damping member 13 is assembled with the first mounting portion 1121, the first vibration damping portion 131 can be arranged in the mounting groove 1121b through the first notch 1121c, so that at least part of the first vibration damping portion 131 is limitedly fitted in the mounting groove 1121b, and at the same time, the first part 1121a is inserted between the second vibration damping portion 132 and the third vibration damping portion 133, which facilitates the installation of the vibration damping member 13 and is beneficial to improving the assembly efficiency of the motor assembly 1; at this time, the first vibration damping portion 131 can be used to separate the first mounting portion 1121 from the first fastener 14, and the third vibration damping portion 133 can separate the first mounting portion 1121 from the second mounting portion 1211a, so as to achieve the purpose of buffering and vibration reduction.

[0058] For example, Figure 5As shown, the first vibration damping portion 131 is formed into a columnar structure (e.g., a cylindrical structure, etc.), and in the circumferential direction of the motor 11, the width of the first notch 1121c is smaller than the maximum width of the mounting groove 1121b, so that the first notch 1121c can limit the first vibration damping portion 131 from being easily separated from the mounting groove 1121b to a certain extent; the second vibration damping portion 132 and the third vibration damping portion 133 are respectively arranged at the axial ends of the first vibration damping portion 131, and on the radial plane of the motor 11, at least part of the outer edge of the orthographic projection of the second vibration damping portion 132 is located at the first vibration damping portion 132. The third vibration damper 133 is located outside the orthographic projection of the first vibration damper 131, and at least a portion of the outer edge of the orthographic projection of the third vibration damper 133 is located outside the orthographic projection of the first vibration damper 131. Then, in the radial direction of the motor 11, the second vibration damper 132 extends out of the first vibration damper 131, so that the portion of the second vibration damper 132 extending out of the first vibration damper 131 stops at one axial end of the first portion 1121a, and the third vibration damper 133 extends out of the first vibration damper 131, so that the portion of the third vibration damper 133 extending out of the first vibration damper 131 stops at the other axial end of the first portion 1121a.

[0059] In some embodiments, Figure 5 As shown, the vibration damper 13 further includes a fourth vibration damper 134, which is connected between the radial outer end of the second vibration damper 132 and the radial outer end of the third vibration damper 133, and the fourth vibration damper 134 is spaced apart from the first vibration damper 131, and the fourth vibration damper 134 is spaced apart outside the first vibration damper 131 in the radial direction of the motor 11. Thus, it is beneficial to further appropriately improve the vibration damping capacity of the vibration damper 13, and at the same time, the arrangement of the fourth vibration damper 134 is not likely to affect the overall installation of the vibration damper 13.

[0060] In some embodiments, Figure 5 As shown, the first mounting portion 1121 further includes a second portion 1121d, the second portion 1121d is disposed at one axial end of the first portion 1121a, and the second portion 1121d is formed with a receiving groove 1121e, the receiving groove 1121e axially penetrates the second portion 1121d, and the receiving groove 1121e is communicated with the mounting groove 1121b, and a second notch 1121f of the receiving groove 1121e is formed on the outer side wall of the second portion 1121d, and the outer side of the second portion 1121d The wall can be understood as the side wall of the second part 1121d that faces away from the central axis L of the motor 11; the end of the first fastener 14 and the second vibration damping portion 132 are both accommodated in the accommodating groove 1121e, then the first fastener 14 can be penetrated through the first vibration damping portion 131 and the second mounting portion 1211a along the axial direction of the motor 11, so that the end of the first fastener 14 is accommodated in the accommodating groove 1121e, and the second vibration damping portion 132 is suitable for being accommodated in the accommodating groove 1121e through the second notch 1121f.

[0061] It can be seen that in the above scheme, the end of the first fastener 14 and the second vibration damping portion 132 will not protrude from the first mounting portion 1121, so that the first mounting portion 1121 can play a certain protective role on the first fastener 14 and the second vibration damping portion 132, and it is not easy to bump into the first fastener 14 and the second vibration damping portion 132.

[0062] For example, taking the axial direction of the motor 11 as the front-to-back direction, the second portion 1121d is arranged at the front side of the first portion 1121a, and the entire groove structure corresponding to the mounting groove 1121b and the receiving groove 1121e can penetrate the first mounting portion 1121 along the axial direction of the motor 11. Since the first portion 1121a is sandwiched between the second vibration damping portion 132 and the third vibration damping portion 133, the entire groove corresponding to the mounting groove 1121b and the receiving groove 1121e is roughly a stepped groove; the vibration damping member 13 is close to the first mounting portion 1121 along the radial direction of the motor 11, so that the first The vibration damping portion 1311 is clamped in the mounting groove 1121b through the first notch 1121c, the second vibration damping portion 132 is accommodated in the accommodating groove 1121e through the second notch 1121f, and the third vibration damping portion 133 is stopped on the rear end surface of the first portion 1121a. The first fastener 14 passes through the accommodating groove 1121e from front to back and penetrates the first vibration damping portion 131 and the corresponding second mounting portion 1211a. The front end of the first fastener 14 is accommodated in the accommodating groove 1121e to realize the connection between the first mounting portion 1121 and the second mounting portion 1211a.

[0063] In some embodiments, Figure 4 and Figure 6 As shown, the bracket 12 includes a first mounting plate 121, and the first mounting plate 121 is formed with a protruding portion 1211 protruding toward the side where the motor 11 is located. The protruding portion 1211 is sleeved on the outside of the motor 11, and a plurality of second mounting portions 1211a are formed on the protruding portion 1211, and a part of the motor 11 is accommodated in the protruding portion 1211. It can be seen that by providing the protruding portion 1211, on the one hand, the structural strength of the first mounting plate 121 can be enhanced to a certain extent, and the bearing capacity of the first mounting plate 121 can be improved. On the other hand, a certain space can be provided for the motor 11, so that the second mounting portion 1211a corresponds to the first mounting portion 1121 in the axial direction of the motor 11, and it is beneficial to reduce the length difference of the motor 11 extending out of the protruding portion 1211 on both sides in the axial direction, improve the force of the protruding portion 1211, and facilitate further improving the installation reliability of the motor 11.

[0064] Exemplarily, the first mounting plate 121 may include a main body portion 121a and a protrusion 1211, and the motor 11 is arranged on one side of the thickness of the main body portion 121a. The protrusion 1211 protrudes toward the side where the motor 11 is located along the thickness direction of the first mounting portion 121, so that a certain accommodation space is defined in the protrusion 1211, and the accommodation space is located on one side of the thickness of the protrusion 1211. A matching hole is formed on the protrusion 1211, and the motor 11 is matched with the matching hole and is accommodated in the accommodation space of the protrusion 1211 through the matching hole.

[0065] In some embodiments, Figure 1-Figure 4 , Figure 6 As shown, the bracket 12 includes a first mounting plate 121 and a second mounting plate 122, and a plurality of second mounting portions 1211a are formed on the first mounting plate 121, and the motor 11 is mounted on the first mounting plate 121; at least one of a first reinforcing rib 1212, a second reinforcing rib 1213 and a third reinforcing rib 1214 is also formed on the first mounting plate 121, the first reinforcing rib 1212 extends along the circumference of the motor 11 and the first reinforcing rib 1212 is located between two adjacent second mounting portions 1211a, the second reinforcing rib 1213 extends into a ring shape and the second reinforcing rib 1213 is arranged around the second mounting portion 1211a, and the third reinforcing rib 1214 is arranged at the lower end of the first mounting plate 121 and the third reinforcing rib 1214 is arranged at intervals below the motor 11.

[0066] It can be seen that by providing at least one of the first reinforcing rib 1212, the second reinforcing rib 1214 and the third reinforcing rib 1214 on the first mounting plate 121, it is beneficial to improve the structural strength of the first mounting plate 121, improve the bearing capacity of the first mounting plate 121, and facilitate improving the installation reliability of the motor 11. In addition, the first reinforcing rib 1212 can improve the structural strength of the portion of the first mounting plate 121 surrounding the motor 11, the second reinforcing rib 1213 can appropriately improve the structural strength at the second mounting portion 1211a, and the second reinforcing rib 1213 can appropriately improve the structural strength between adjacent second mounting portions 1211a, then the first reinforcing rib 1212 and the second reinforcing rib 1213 can both appropriately improve the structural strength of the first mounting plate 121 corresponding to the mounting position of the motor 11 (such as the protruding portion 1211 described above); when the first mounting plate 121 is installed on other components, if the first mounting plate 121 is arranged vertically, the provision of the third reinforcing rib 1214 can improve the structural strength of the lower end of the first mounting plate 121, reduce the deformation of the first mounting plate 121, and facilitate the first mounting plate 121 to stably support the motor 11. Optionally, at least one of the first reinforcing rib 1212, the second reinforcing rib 1213 and the third reinforcing rib 1214 can be configured as a convex rib or a groove.

[0067] It is understandable that the second reinforcing rib 1213 extends into a ring shape, including the second reinforcing rib 1213 extending into a closed ring shape and the second reinforcing rib 1213 extending into an open ring shape. It should be noted that the "open ring shape" described herein refers to: a ring shape with an opening (i.e., a non-closed ring shape), wherein "ring shape" is to be understood in a broad sense, i.e., not limited to a "circular ring shape", for example, it can also be a "polygonal ring" and so on. For example, Figure 6-Figure 8 As shown, the second reinforcing rib 1213 extends into an open circular ring shape (ie, an arc shape).

[0068] For example, in Figure 2 and Figure 6 In the example, the first mounting plate 121 is formed with a protrusion 1211 protruding toward the side where the motor 11 is located, the protrusion 1211 is sleeved on the outside of the motor 11, a plurality of second mounting portions 1211a are formed on the protrusion 1211, a part of the motor 11 is accommodated in the protrusion 1211, the first reinforcement rib 1212 and the third reinforcement rib 1213 are both formed on the protrusion 1211, and the third reinforcement rib 1214 is spaced below the protrusion 1211.

[0069] In some embodiments, Figure 6-Figure 9 As shown, the bracket 12 includes a first mounting plate 121 and a second mounting plate 122, and a plurality of second mounting portions 1211a are formed on the first mounting plate 121, and the motor 11 is mounted on the first mounting plate 121; a wiring groove 1215 is also formed on the first mounting plate 121, and the wiring groove 1215 is used to arrange the connecting wires 110 (such as power lines, etc.) of the motor 11, and the second mounting plate 122 is covered on the open side of the wiring groove 1215 and the second mounting plate 122 is detachably connected to the first mounting plate 121.

[0070] It can be seen that in the above scheme, the second mounting plate 122 can play a certain restrictive role on the connecting wire 110 in the wiring groove 1215, reduce the risk of the connecting wire 110 being separated from the wiring groove 1215, and improve the wiring reliability; at the same time, since the second mounting plate 122 and the first mounting plate 121 are detachable, it is convenient for subsequent maintenance of the motor 11.

[0071] Optionally, the second mounting plate 122 and the first mounting plate 121 are detachable by threaded fasteners such as screws, and at least one first connection hole 121b is formed on the first mounting plate 121, and at least one second connection hole 122a is formed on the second mounting plate 122. The threaded fasteners are inserted through the first connection hole 121b and the corresponding second connection hole 122b. For example, at least one first connection hole 121b is respectively provided on both sides of the width of the wiring groove 1215.

[0072] For example, in Figure 2 and Figure 6In the example, the first mounting plate 121 is formed with a protrusion 1211 protruding toward the side where the motor 11 is located, the protrusion 1211 is sleeved on the outside of the motor 11, and multiple second mounting portions 1211a are formed on the protrusion 1211. A part of the motor 11 is accommodated in the accommodating space within the protrusion 1211. A connecting hole 1211b is formed on the protrusion 1211, and the connecting hole 1211b passes through the protrusion 1211 to connect the inside and outside of the protrusion 1211. The connecting wire 110 can pass through the connecting hole 1121a from the inside of the protrusion 1211 to the outside of the protrusion 1211 and be arranged in the wiring groove 1215.

[0073] In some embodiments, Figure 6 and Figure 7 As shown, the first mounting plate 121 is also provided with a plurality of first limiting buckles 1216, which are used to limit the movement of the second mounting plate 122 in the width direction of the wiring groove 1215, and the second mounting plate 122 is fixed to the first mounting plate 121 by a second fastener. It can be seen that the first limiting buckle 1216 can realize the pre-limitation of the second mounting plate 122 to a certain extent, so as to facilitate the subsequent installation of the second fastener, which is conducive to improving the assembly efficiency of the second mounting plate 122 and the first mounting plate 121. Optionally, the second fastener can be a threaded fastener, such as a screw, a bolt, etc. Among them, the plurality of first limiting buckles 1216 are respectively arranged on both sides of the width of the wiring groove 1215, or the plurality of first limiting buckles 1216 are arranged on the same side of the width of the wiring groove 1215.

[0074] For example, Figure 6 and Figure 7 As shown, the wiring groove 1215 extends vertically, and at least one first limit buckle 1216 is respectively provided on the left and right sides of the wiring groove 1215 to limit the movement of the second mounting plate 122 in the left and right directions. At this time, the second mounting plate 122 can be inserted between the first limit buckles 1216 on the left and right sides in the vertical direction to be opposite to the wiring groove 1215 front and back, so as to cover the open side of the wiring groove 1215. Optionally, the first limit buckle 1216 may include a first plate and a second plate connected by bending, and the first limit portion 1216 is generally in an L-shaped structure.

[0075] In some embodiments, Figure 3As shown, the end of the second mounting plate 122 facing the motor 11 is formed with an arc-shaped bending portion 1221 extending in a direction away from the wiring groove 1215, so that the connecting wire 110 of the motor 11 is arranged on the end of the second mounting plate 122 facing the motor 11, and the arc-shaped bending portion 1211 will not cause significant scratches and wear on the connecting wire 110, thereby protecting the connecting wire 110. Exemplarily, the motor 11 is arranged on the upper side of the wiring groove 1215, the second mounting plate 122 is arranged on the front side of the first mounting plate 121, and the upper end of the second mounting plate 122 is formed with an arc-shaped bending portion 1221 extending forward.

Thus, the wiring groove 1215 is defined between the two convex ribs 1217, which facilitates the formation of the wiring groove 1215, and at the same time, under the condition of the same depth of the wiring groove 1215, it is conducive to reducing the height of the bottom wall of the wiring groove 1215 protruding from the back side of the first mounting plate 121, so as to reduce the influence of the wiring groove 1215 on the installation of the first mounting plate 121.

[0077] For example, in Figure 6-Figure 8 In the example, the wiring groove 1215 is recessed from front to back, and convex ribs 1217 are respectively provided on the left and right sides of the wiring groove 1215. The convex ribs 1217 protrude from back to front, and the rear side groove bottom wall of the wiring groove 1215 is basically flush with the main body 121a of the first mounting plate 121.

[0078] In some embodiments, Figure 6-Figure 8 As shown, the wiring groove 1215 is located at the lower side of the motor 11 and the wiring groove 1215 extends vertically, and the third reinforcing ribs 1214 extending in the horizontal direction are respectively provided on both sides of the width of the wiring groove 1215. When the first mounting plate 121 is installed on other components, if the first mounting plate 121 is arranged vertically, the provision of the third reinforcing ribs 1214 can enhance the structural strength of the lower end of the first mounting plate 121 and both sides of the width of the wiring groove 1215, so that the first mounting plate 121 can stably support the motor 11. Exemplarily, convex ribs 1217 protruding in the direction of the concave direction of the wiring groove 1215 are respectively provided on both sides of the width of the wiring groove 1215, and each convex rib 1217 corresponds to at least one third reinforcing rib 1214 extending horizontally, and the third reinforcing rib 1214 extends to the corresponding convex rib 1217.
