Description

Technical Field

[0001] This application relates to the technical field of air conditioner structures, and particularly to a motor mounting structure and an air conditioner. Background Art

[0002] With the development and progress of technology, people's quality of life has been continuously improved, and air conditioners have gradually become essential household appliances. Moreover, users' requirements for the comfort of air conditioners are getting higher and higher. In the related art, an installation base for a motor is provided inside an air conditioner. During operation, the common cross-flow fan motor may shift. Due to the structural limitations of the installation base, when the motor shifts, it will collide with the installation base, transmitting relatively large vibrations to the air conditioner housing and even the external wall, thereby causing the air conditioner to generate relatively large noise and affecting the user experience. Utility Model Content

[0003] An embodiment of this application provides a motor mounting structure and an air conditioner, aiming to reduce the vibrations transmitted by the motor to reduce the noise generated by the air conditioner.

[0004] On the one hand, an embodiment of this application provides a motor mounting structure, including: a base provided with a motor mounting portion for mounting a motor; the motor has a motor body and a journal, the motor mounting portion has a motor mating surface, and shock-absorbing protrusions are provided on the motor mating surface for contact and cooperation with the end surface of the motor body near the journal.

[0005] In some embodiments, a flange portion protrudes from the bottom wall of the motor mounting portion. The flange portion divides the motor mounting portion into a body mounting groove and a journal mounting groove. The side of the flange portion close to the inside of the body mounting groove is the motor mating surface and protrudes with the shock-absorbing protrusions.

[0006] In some embodiments, a plurality of shock-absorbing protrusions are provided, and the plurality of shock-absorbing protrusions are sequentially and spaced apart along the extending direction of the flange portion.

[0007] In some embodiments, the plurality of shock-absorbing protrusions are distributed in a circumferential array, and the included angle between two adjacent shock-absorbing protrusions is 22 to 28 degrees.

[0008] In some embodiments, a plugging structure is provided on the bottom wall of the body mounting groove. The plugging structure is arranged corresponding to the groove on the outer circumference of the motor body, and the plugging structure is in interference fit with the groove.

[0009] In some embodiments, the plugging structure is in the shape of a frustum of a pyramid. The top surface of the plugging structure faces the bottom of the groove, and the side surface of the plugging structure is used to abut against the groove side wall.

[0010] In some embodiments, the plugging structure is cylindrical, and a spherical head is provided at an end of the plugging structure, and the spherical head is used to abut against the bottom of the groove.

[0011] In some embodiments, a limiting structure is provided at an end of the motor mounting portion away from the motor mating surface. The limiting structure is provided with a connected first retaining edge and a stop portion. The first retaining edge is provided with a chamfer facing the motor mating surface, and one end of the motor body away from the journal slides along the chamfer onto the stop portion.

[0012] In some embodiments, a heat conduction channel is provided through the bottom wall of the base. The heat conduction channel is spaced apart from the side wall of the base, and a chamfer is provided at an edge of the heat conduction channel close to the side wall of the base.

[0013] In some embodiments, a plurality of heat conduction channels are provided, and the plurality of heat conduction channels are spaced apart from each other. The heat conduction channels are waist-shaped channels, trapezoidal channels, corrugated channels or circular channels.

[0014] On the other hand, an embodiment of the present application provides an air conditioner, including the motor mounting structure as described above.

[0015] In an embodiment of the present application, the motor is mounted into the motor mounting portion from the side of the base. A motor mating surface is provided in the motor mounting portion. Shock-absorbing protrusions are provided on the motor mating surface, and the shock-absorbing protrusions extend toward the end face of the motor body and are used to abut against the end face of the motor body close to the journal side. When the motor body is mounted in the motor mounting portion, most of the surface of the motor body is spaced apart from the base, that is, only the end of the motor body close to the journal contacts the base through the shock-absorbing protrusions. Such a setting can reduce the contact area between the end face of the motor body close to the journal and the base, so as to reduce the vibration transmitted to the base when the motor collides. As the vibration decreases, the vibration transmission ability is also weakened. In this way, the vibration transmitted to the air conditioner housing or even the external wall can be reduced, and the noise generated by the vibration of the internal structure of the air conditioner or the slight collision between the air conditioner housing and the wall can be reduced, improving the comfort of the user.

It should be understood that those of ordinary skill in the art can recognize that the present application can be implemented without the use of these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0032] An embodiment of the present application provides a motor mounting structure, such as Figures 1 to 9As shown in the figure, the motor mounting structure is applied to an air conditioner. The air conditioner includes a motor and a housing 2. The motor mounting structure is mounted on the side of the housing 2. The motor mounting structure includes a base 1, and the base 1 is provided with a motor mounting portion for mounting the motor. The motor has a motor body 31 and a journal 32. The rotating shaft of the motor is disposed on the side of the journal 32 away from the motor body 31. The motor mounting portion has a motor mating surface 11, and shock-absorbing protrusions 12 are provided on the motor mating surface 11. The shock-absorbing protrusions 12 are used for contact and cooperation with the end surface of the motor body 31 near one end of the journal 32.

[0033] In the related art, the motor may shift during operation, and the end surface of the motor may directly and rigidly contact and collide with the side of the mounting base 1. The larger the area of the position where the motor contacts the base 1, the greater the vibration transmitted during the collision.

[0034] In the embodiment of the present application, the motor is mounted into the motor mounting portion from the side of the base 1. A motor mating surface 11 is provided in the motor mounting portion. Shock-absorbing protrusions 12 are provided on the motor mating surface 11. The shock-absorbing protrusions 12 extend toward the end surface of the motor body 31 and are used for abutting against the end surface of the motor body 31 near one side of the journal 32. When the motor body 31 is mounted in the motor mounting portion, most of the surface of the motor body 31 is spaced from the base 1, that is, only the end of the motor body 31 near the journal 32 contacts the base 1 through the shock-absorbing protrusions 12. Such a setting can reduce the contact area between the end surface of the motor body 31 near the journal 32 and the base 1, so that the vibration transmitted to the base 1 during the collision of the motor is reduced. As the vibration is reduced, the vibration transmission ability is also weakened. In this way, the vibration transmitted to the air conditioner housing 2 or even the external wall can be reduced, and the noise generated by the vibration of the internal structure of the air conditioner or the slight collision between the air conditioner housing 2 and the wall can be reduced, improving the comfort of the user.

[0035] In some embodiments, a flange portion 13 protrudes from the bottom wall of the motor mounting portion. The flange portion 13 divides the motor mounting portion into a body mounting groove 14 and a journal mounting groove 15. The side of the flange portion 13 near the inside of the body mounting groove 14 is the motor mating surface 11 and shock-absorbing protrusions 12 protrude therefrom.

[0036] Specifically, the flange portion 13 is a convex edge structure convexly provided between the body mounting groove 14 and the journal mounting groove 15. The flange portion 13 is arc-shaped. The motor body 31 includes a main body portion 31a and a boss portion 31b. The diameter of the main body portion 31a is greater than that of the boss portion 31b. The journal 32 is inserted into the boss portion 31b. The body mounting groove 14 includes a main body groove 141 and a supporting groove 142. The main body groove 141 is used for mounting the main body portion 31a, and the supporting groove 142 is used for mounting the boss portion 31b. The supporting groove 142 and the main body groove 141 are separated by the side wall of the base 1. When the main body portion 31a is mounted in the main body groove 141, the outer peripheral wall of the main body portion 31a is spaced from the bottom wall of the main body groove 141. The bottom wall of the supporting groove 142 is an arc surface. The bottom wall of the supporting groove 142 is used for supporting the boss portion 31b, that is, the outer periphery of the boss portion 31b abuts against the bottom wall of the supporting groove 142. The flange portion 13 is convexly provided on the bottom wall of the supporting groove 142 and extends along the extending direction of the bottom wall of the supporting groove 142. The side of the flange portion 13 facing the boss portion 31b is the side wall of the supporting groove 142. The side wall of the supporting groove 142 is the motor mating surface 11, that is, shock-absorbing protrusions 12 are convexly provided on the side wall of the supporting groove 142. Such a setting supports the boss portion 31b of the motor body 31 through the supporting groove 142, thereby realizing the support of the base 1 for the motor, making the main body groove 141 spaced from the body portion of the motor. The flange portion 13 can limit the motor, so that the contact between the motor and the base 1 can be further reduced, and the transmission of vibration can be further reduced. In some other embodiments, a plurality of limiting bosses are convexly provided between the body mounting groove 14 and the journal mounting groove 15. The plurality of limiting bosses are spaced in sequence. The sides of the plurality of limiting bosses facing the motor body 31 together form the motor mating surface 11. The plurality of limiting bosses together abut against the end surface of the motor body 31 near the journal 32.

[0037] Further, the width of the main body groove 141 can be adjusted according to the actual length of the motor body 31. The main body groove 141 is an annular groove, and the radius of the main body groove 141 can also be adjusted according to the radius of the motor body 31.

[0038] In some embodiments, there are a plurality of shock-absorbing protrusions 12, and the plurality of shock-absorbing protrusions 12 are spaced in sequence along the extending direction of the flange portion 13.

[0039] Specifically, in this embodiment, the shock-absorbing protrusions 12 are annular bump structures, which can change the surface contact between the motor body 31 and the flange portion 13 into point contact, reducing the contact area. A plurality of shock-absorbing protrusions 12 are provided on the flange portion 13, and the plurality of shock-absorbing protrusions 12 are evenly spaced along the extending direction of the flange portion 13. Such a setting can add multiple contact points to the flange portion 13, so that when the motor body 31 abuts against the flange portion 13, the plurality of shock-absorbing protrusions 12 act together to ensure the stability when the motor body 31 abuts, so that the motor body 31 will not be displaced in other directions when colliding with the flange portion 13. At the same time, the plurality of shock-absorbing protrusions 12 can jointly share the impact force from the motor body 31, improving the service life of the shock-absorbing protrusions 12. In some other embodiments, the shock-absorbing protrusions 12 are frustum structures, cylindrical structures or frustum of a cone structures, and the plurality of shock-absorbing protrusions 12 are randomly distributed on the flange portion 13.

[0040] In some embodiments, the plurality of shock-absorbing protrusions 12 are arranged in a circumferential array, and the included angle between two adjacent shock-absorbing protrusions 12 is 22 to 28 degrees.

[0041] Specifically, in this embodiment, the flange portion 13 is a semi-circular ring, and the plurality of shock-absorbing protrusions 12 are arranged in a circumferential array on the semi-circular ring. There is an included angle between two adjacent shock-absorbing protrusions 12, and the included angle is 22 degrees, 23 degrees, 24 degrees, 25 degrees, 26 degrees, 27 degrees or 28 degrees. With such a setting, arranging the shock-absorbing protrusions 12 under the limitation of this included angle can ensure that the interval between the plurality of shock-absorbing protrusions 12 is not too large, and can limit the number of shock-absorbing protrusions 12 through the included angle, avoiding too many shock-absorbing protrusions 12, and can also perform uniform torque balance on the premise of avoiding hard contact between the motor body 31 and the flange portion 13. In some other embodiments, the plurality of shock-absorbing protrusions 12 are sequentially spaced along the extending direction of the flange portion 13, but the interval gradually increases or gradually decreases.

[0042] In some embodiments, a plugging structure 16 is provided on the bottom wall of the body installation groove 14, and the plugging structure 16 is arranged corresponding to the groove on the outer periphery of the motor body 31, and the plugging structure 16 is in interference fit with the groove.

[0043] Specifically, in this embodiment, the plugging structure 16 is arranged on the bottom wall of the supporting groove 142. There are a plurality of plugging structures 16, and a plurality of grooves are formed on the outer peripheral wall of the boss portion 31b of the motor body 31. The plurality of plugging structures 16 and the plurality of grooves are correspondingly arranged on the bottom wall of the supporting groove 142. When the motor body 31 is placed in the body installation groove 14, the plugging structure 16 can be inserted into the groove, and the plugging structure 16 is in interference fit with the groove, making the connection between the plugging structure 16 and the groove tight, so as to limit the motor body 31 in the circumferential direction. Such a setting can increase the installation stability of the motor and also reduce the possibility of the motor being displaced.

[0044] In some embodiments, the plugging structure 16 is frustum-shaped, the top surface of the plugging structure 16 faces the bottom of the groove, and the side surface of the plugging structure 16 is used to abut against the side wall of the groove.

[0045] Specifically, the plugging structure 16 is frustum-shaped and extends upward from the bottom wall of the supporting groove 142. The width of the frustum gradually decreases. When the frustum is plugged into the groove, the two side walls of the frustum respectively abut against the two side walls of the groove. The frustum has a small-area surface contact with the groove. With this setting, when the boss portion 31b is placed in the supporting groove 142, the plugging structure 16 can lift the boss portion 31b, so that the outer periphery of the boss portion 31b does not abut against the bottom wall of the supporting groove 142, further reducing the contact area between the motor body 31 and the base 1, thereby reducing the transmission of vibration.

[0046] In another embodiment, the plugging structure 16 is cylindrical, and a spherical head is provided at the end of the plugging structure 16, and the spherical head is used to abut against the bottom of the groove.

[0047] Specifically, the plugging structure 16 is divided into two parts. The part protruding from the supporting groove 142 is a prism, and a hemispherical spherical head is provided at the top of the prism. The width of the prism is slightly smaller than the width of the groove. When the boss portion 31b is placed in the supporting groove 142, the inner wall of the groove is in line contact with the spherical head. When the motor is running, the motor body 31 has a tendency to rotate. At this time, the side wall of the prism can also participate in abutting against the inner wall of the groove, further limiting the motor body 31; One of the present embodiment and the above embodiment can be selected and arranged in the supporting groove 142, or both embodiments can be arranged in the supporting groove 142 for use.

[0048] In some embodiments, a limiting structure 17 is provided at one end of the motor mounting portion away from the motor mating surface 11. The limiting structure 17 is provided with a connected first flange 171 and a rabbet portion 172. The first flange 171 is provided with a chamfer facing the motor mating surface 11. One end of the motor body 31 away from the journal 32 slides along the chamfer onto the rabbet portion 172.

[0049] Specifically, a limiting structure 17 is provided on one side of the body installation groove 14 away from the journal installation groove 15, that is, the limiting structure 17 is provided at the opposite end of the side wall of the base 1. The motor moves inward from this position of the limiting structure 17 so as to set the motor body 31 in the body installation groove 14. When the end of the motor body 31 away from the journal 32 is placed, it can slide downward along the chamfer to the stop portion 172. The stop portion 172 is a boss structure for placing the motor body 31. The included angle between the hypotenuse of the chamfer of the first edge 171 and the upper end surface of the first edge 171 is 145 degrees. The chamfer does not completely extend to the stop portion 172, and there is a straight edge between the bottom end of the hypotenuse and the stop portion 172. Another chamfer is provided at the lower end of the stop portion 172, and the included angle between the hypotenuse of this chamfer and the vertical direction is 126 degrees. With such a setting, the first edge 171 can limit the end of the motor body 31 away from the journal 32 to prevent the motor from detaching from the base 1, and the chamfer of the first edge 171 can guide the motor body 31 into the body installation groove 14, facilitating the installation of the motor.

[0050] In some embodiments, a heat conduction channel 18 penetrates through the bottom wall of the base 1. The heat conduction channel 18 is arranged at an interval from the side wall of the base 1, and a chamfer is provided at the edge of the heat conduction channel 18 close to the side wall of the base 1.

[0051] Specifically, in this embodiment, a heat conduction channel 18 penetrates through the bottom wall of the main body groove 141. The heat conduction channel 18 communicates the motor installation part with the outside. A chamfer is provided at one edge of the heat conduction channel 18 close to the side wall of the base 1. The included angle between the hypotenuse formed by this chamfer and the vertical direction is 149, 150, 151, 152, 153, 154, 155, 156, 157, 158 or 159 degrees. In this embodiment, this included angle is 154 degrees. With such a setting, the hypotenuse can be relatively close to the vertical, which can guide the heat generated by the motor into the heat conduction channel 18, and can also ensure the rapid outflow of the heat close to the side wall of the base 1. Moreover, the distance between the edge of the heat conduction channel 18 close to the side wall and the side wall is 5, 6, 7 or 8 millimeters.

[0052] In some embodiments, there are multiple heat conduction channels 18. The multiple heat conduction channels 18 are spaced from each other. The heat conduction channels 18 are waist-shaped channels 18a, trapezoidal channels 18b, corrugated channels 18c or circular channels 18d.

[0053] Specifically, there are at least four heat conduction channels 18. There are 8 heat conduction channels 18 provided on the main body groove 141. In the left-to-right direction, two waist-shaped channels 18a are provided first. The two waist-shaped channels 18a are arranged in parallel. Secondly, two trapezoidal channels 18b arranged in parallel are provided. Then, a corrugated channel 18c is provided. The corrugated channel 18c is arranged in an overall S shape. Then, two circular channels 18d arranged in parallel are provided. Finally, a waist-shaped channel 18a is provided. Among them, the trapezoidal channel 18b has a structure with a larger upper side and a smaller lower side. The upper side is used for rapid drainage, and the lower side is used for concentrating heat dissipation. The trapezoidal single-side inclination angle is 111 degrees to 123 degrees; the corrugated channel 18c has an inlet section and an outlet section. The inlet section is used for rapid drainage, and the outlet section is used for rapid outflow. The inclination angle of the inlet section is 103 degrees to 117 degrees, and the inclination angle of the outlet section is 112 degrees.
