Description

Technical Field

[0001] This invention belongs to the field of air conditioning technology, specifically relating to an electric motor and an air conditioner having the same. Background Technology

[0002] Currently, the motor industry uses ordinary motors with mounting brackets to meet the installation requirements of loads such as air conditioners. Existing ordinary mounting brackets are fastened to the motor via an interference fit. During interference fit installation, operators need to press the mounting bracket firmly to ensure it is in place, which is difficult. Furthermore, excessive pressure can easily damage the conductive tape on the motor surface when the mounting bracket comes into contact with it. Summary of the Invention

[0003] Therefore, the present invention provides a motor that can solve the technical problem that the conductive tape is easily damaged when the mounting bracket is fastened to the motor by interference fit.

[0004] To address the aforementioned problems, the present invention provides a motor comprising a front end cover, a conductive tape, a flexible component, and a first support component. The front end cover has a front protrusion, within which a front bearing chamber is formed. The conductive tape covers the portion of the front end cover excluding the front protrusion. The flexible component and the first support component are both fitted onto the front protrusion, and the flexible component is sandwiched between the first support component and the conductive tape.

[0005] In some embodiments, the first support member has a first mounting channel that extends through the first support member along its height direction. A first internal thread is formed on the channel wall of the first mounting channel, and a first external thread is formed on the outer peripheral wall of the front protrusion. The first support member is fitted onto the front protrusion through the first mounting channel, and the first internal thread and the first external thread are threadedly connected.

[0006] In some embodiments, the first support member includes a first main body, which includes an inner ring body, an outer ring body, and a plurality of connecting bodies. One side of each connecting body is connected to the inner ring body, and the other side of each connecting body is connected to the outer ring body. The connecting bodies are distributed circumferentially at intervals within the space formed between the inner ring body and the outer ring body. The first internal thread is formed on the inner peripheral wall of the inner ring body.

[0007] In some embodiments, a reinforcing rib is connected between two adjacent connecting bodies.

[0008] In some embodiments, the first support member has a first mounting channel that extends through the first support member along its height direction. The first support member is fitted onto the front protrusion through the first mounting channel. A first waterproof cover is provided on the side of the first support member away from the flexible member, and the first waterproof cover covers the end of the first mounting channel away from the flexible member.

[0009] In some embodiments, a second support member is assembled on the first support member. The second support member has a receiving cavity and a second mounting channel. The first waterproof cover is located inside the receiving cavity. One end of the second mounting channel opens into the receiving cavity, and the other end of the second mounting channel opens to the outside of the second support member. A second waterproof cover is provided on the side of the second support member away from the first support member, and the second waterproof cover covers the end of the second mounting channel away from the receiving cavity.

[0010] In some embodiments, a second internal thread is formed on the cavity wall of the receiving cavity, a second external thread is formed on the outer peripheral wall of the first support member, the second support member is fitted onto the first support member through the receiving cavity, and the second internal thread is threadedly connected to the second external thread.

[0011] In some embodiments, the second support member is provided with a drainage channel, and the receiving cavity communicates with the outside of the second support member through the drainage channel.

[0012] In some embodiments, the flexible component has a first positioning structure on the side facing the first support component, and the first support component has a first positioning engagement structure on the side facing the flexible component, wherein the first positioning structure and the first positioning engagement structure are positioned and engaged; and / or, the flexible component has a second positioning structure on the side away from the first support component, and the front end cover has a second positioning engagement structure, wherein the second positioning structure and the second positioning engagement structure are positioned and engaged.

[0013] The present invention provides an electric motor and an air conditioner having the same, which have the following beneficial effects:

[0014] Because the added flexible component prevents direct contact between the first support component and the conductive tape, it effectively prevents the first support component from damaging the conductive tape during installation. Furthermore, it secures the conductive tape, allowing it to effectively conduct electricity across the front and rear end covers of the motor, eliminating motor shaft voltage and preventing motor corrosion. Simultaneously, the flexible component also provides cushioning and shock absorption, eliminating resonance noise between the motor body and the first support component. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0036] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0037] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0038] See also Figures 1 to 16 As shown, according to an embodiment of the present invention, a motor is provided, including a front cover 1, a conductive tape 2, a flexible component 3, and a first support component 4. The front cover 1 has a front protrusion 5, and a front bearing chamber is formed in the front protrusion 5. The conductive tape 2 covers the part of the front cover 1 other than the front protrusion 5. The flexible component 3 and the first support component 4 are both fitted on the front protrusion 5, and the flexible component 3 is sandwiched between the first support component 4 and the conductive tape 2.

[0039] In this technical solution, the added flexible component 3 prevents direct contact between the first support component 4 and the conductive tape 2, thus effectively preventing damage to the conductive tape 2 during installation. It also secures the conductive tape 2, allowing it to effectively conduct electricity across the front and rear end covers of the motor, eliminating motor shaft voltage and preventing motor corrosion. Simultaneously, the flexible component 3 also provides vibration damping, altering the natural frequencies of the motor body and the first support component 4. This ensures that their natural frequencies do not coincide within the operating speed range, thereby eliminating resonance noise between the motor body and the first support component 4. The flexible component 3 can be made of soft materials such as silicone rubber or EPDM.

[0040] See also Figure 1 , Figure 5 and Figure 7As shown, the first support member 4 has a first mounting channel 6, which extends through the first support member 4 along its height direction. A first internal thread 7 is formed on the channel wall of the first mounting channel 6, and a first external thread 8 is formed on the outer peripheral wall of the front protrusion 5. The first support member 4 is fitted onto the front protrusion 5 through the first mounting channel 6, and the first internal thread 7 and the first external thread 8 are threadedly connected.

[0041] In this embodiment, the mounting bracket 23 in the prior art is interference-fitted with the front protrusion 5 of the front cover 1. This fastening method requires manual pressing, which carries the risk of damaging the mounting bracket 23 due to insufficient pressing. However, the first support component 4 of this application is threadedly connected to the front protrusion 5 of the front cover 1. Compared to the interference fit, its installation is simpler and more reliable, requiring only tightening, and there is no risk of damaging the first support component 4.

[0042] See also Figure 8 and Figure 9 As shown, the first support component 4 includes a first main body 41, which includes an inner ring 411, an outer ring 412, and a plurality of connecting bodies 413. One side of each connecting body 413 is connected to the inner ring 411, and the other side of each connecting body 413 is connected to the outer ring 412. The connecting bodies 413 are circumferentially spaced within the space formed between the inner ring 411 and the outer ring 412. A first internal thread 7 is formed on the inner circumferential wall of the inner ring 411.

[0043] In this technical solution, the first main body 41 of the first support component 4 is designed to consist of an inner ring 411, an outer ring 412, and multiple connecting bodies 413 connecting the inner ring 411 and the outer ring 412. While ensuring the structural strength of the first main body 41, it also achieves a degree of hollowness, thus reducing the weight of the first support component 4 and saving material costs. It should be noted that the first support component 4 also includes a first axial extension 42 integrally formed on the first main body 41, and the first axial extension 42 is located on the side of the first main body 41 away from the flexible component 3. The first mounting channel 6 passes through both the inner ring 411 and the first axial extension 42.

[0044] See also Figure 8 and Figure 9 As shown, a reinforcing rib 414 connects two adjacent connecting bodies 413.

[0045] In this embodiment, the arrangement of each reinforcing rib 414 increases the overall structural strength of the first main body 41, thereby increasing the overall structural strength of the first supporting component 4. Each reinforcing rib 414 can be integrally formed between two adjacent connecting bodies 413, and each reinforcing rib 414 forms a ring-shaped structure along the circumference of the first main body 41. The first supporting component 4 can be made of a material such as PA66, which has a certain degree of hardness and can withstand high temperatures.

[0046] See Figure 1 As shown, a first waterproof cover 9 is provided on the side of the first support component 4 away from the flexible component 3, and the first waterproof cover 9 covers the end of the first installation channel 6 away from the flexible component 3.

[0047] In this technical solution, by setting a first waterproof cover 9 to cover the end of the first mounting channel 6 away from the flexible component 3, external water can be prevented from entering the motor through the first mounting channel 6, thus giving the motor a first-level waterproof function. The first waterproof cover 9 can be made of waterproof materials such as silicone rubber or EPDM.

[0048] See Figure 1 As shown, a second support component 10 is assembled on the first support component 4. The second support component 10 has a receiving cavity 11 and a second mounting channel 12. The first waterproof cover 9 is located inside the receiving cavity 11. One end of the second mounting channel 12 leads to the receiving cavity 11, and the other end of the second mounting channel 12 leads to the outside of the second support component 10. A second waterproof cover 13 is provided on the side of the second support component 10 away from the first support component 4. The second waterproof cover 13 covers the end of the second mounting channel 12 away from the receiving cavity 11.

[0049] In this embodiment, by providing a second waterproof cover 13 to cover the end of the second mounting channel 12 away from the first support member 4, external water can be prevented from entering the receiving cavity 11 of the second support member 10 through the second mounting channel 12. Since the first waterproof cover 9 is located inside the receiving cavity 11, preventing external water from entering the receiving cavity 11 further prevents external water from entering the motor through the first mounting channel 6 covered by the first waterproof cover 9. Therefore, the motor has a secondary waterproof function, thereby further improving the motor's waterproof capability. When the motor is used in an air conditioning load, it can better prevent water from entering the motor, protect the air conditioning load, and improve the user experience. The material of the second support member 10 can be PA66 or other materials with a certain hardness and high temperature resistance, and the material of the second waterproof cover 13 can be silicone rubber, EPDM, or other waterproof materials.

[0050] See also Figure 1 , Figure 7 and Figure 10As shown, a second internal thread 14 is formed on the cavity wall of the receiving cavity 11, and a second external thread 15 is formed on the outer peripheral wall of the first support member 4. The second support member 10 is fitted onto the first support member 4 through the receiving cavity 11, and the second internal thread 14 and the second external thread 15 are threadedly connected.

[0051] In this technical solution, the second support component 10 and the first support component 4 are connected by threads, which makes the installation simpler and more reliable, requiring only tightening.

[0052] See also Figure 1 , Figure 7 and Figure 11 As shown, the second support member 10 is provided with a drainage channel 16, and the receiving cavity 11 is connected to the outside of the second support member 10 through the drainage channel 16.

[0053] In this embodiment, by providing a drainage channel 16, water entering the receiving cavity 11 can be discharged in a timely manner.

[0054] The second support member 10 includes a second main body 101 and a second axial extension 102 integrally formed on the second main body 101. The second axial extension 102 is located on the side of the second main body 101 away from the first support member 4. A receiving cavity 11 is formed within the second main body 101, and a second mounting channel 12 is formed within the second axial extension 102. The motor also includes a front damping rubber ring 20, a rear end cover 21, a rear damping rubber ring 22, and a rotating shaft 24. The front damping rubber ring 20 is fitted onto the second axial extension 102 of the second support member 10. The rear end cover 21 has a rear protrusion, and the conductive tape 2 also covers the rear end cover 21. The rear damping rubber ring 22 is fitted onto the rear protrusion and fixes the conductive tape 2. The rotating shaft 24 passes sequentially through the front protrusion 5 of the front cover 1, the first mounting channel 6 of the first support component 4, the first waterproof cover 9, the receiving cavity 11 of the second support component 10, the second mounting channel 12 of the second support component 10, and the second waterproof cover 13. The first waterproof cover 9 and the second waterproof cover 13 are fixed by being fitted onto the rotating shaft 24.

[0055] See also Figure 1 , Figure 3 and Figure 7 As shown, a first positioning structure 17 is formed on the side of the flexible component 3 facing the first support component 4, and a first positioning and mating structure 18 is formed on the side of the first support component 4 facing the flexible component 3. The first positioning structure 17 and the first positioning and mating structure 18 are positioned and mated.

[0056] In this technical solution, the positioning and engagement of the first positioning structure 17 and the first positioning and engagement structure 18 makes the alignment and installation between the first support component 4 and the flexible component 3 more convenient and faster. The first positioning structure 17 can be a first protrusion formed on the flexible component 3, and the first positioning and engagement structure 18 can be a first positioning groove formed on the first support component 4. The first protrusion on the flexible component 3 is inserted into the first positioning groove of the first support component 4 to achieve the positioning and engagement between the first support component 4 and the flexible component 3. Preferably, the cross-sectional shape of the first protrusion on the flexible component 3 is a V-shape with sharp corners, and the shape of the first positioning groove of the first support component 4 matches the shape of the first protrusion on the flexible component 3.

[0057] See also Figure 1 , Figure 3 and Figure 5 As shown, a second positioning structure 19 is formed on the side of the flexible component 3 away from the first support component 4, and a second positioning and mating structure is formed on the front end cover 1. The second positioning structure 19 and the second positioning and mating structure are positioned and mated.

[0058] In this embodiment, the positioning and engagement of the second positioning structure 19 and the second positioning and engagement structure make the alignment and installation between the flexible component 3 and the front cover 1 more convenient and faster. The second positioning structure 19 can be a second protrusion formed on the flexible component 3, and the second positioning and engagement structure can be a second positioning groove formed at the junction of the main body of the front cover 1 and the front protrusion 5. The second protrusion on the flexible component 3 engages with the second positioning groove of the front cover 1 to achieve positioning and engagement between the flexible component 3 and the front cover 1. The flexible component 3 includes a disk body, and the first positioning structure 17 and the second positioning structure 19 are respectively formed on both sides of the disk body, thus forming the flexible component 3.
