[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0019] For ease of description, spatially relative terms such as "above," "above," "on the upper surface of," and "upper" may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in a drawing is inverted, a device described as "above" or "on top of" another device or structure would then be positioned as "below" or "below" the other device or structure. Thus, the exemplary term "above" can include both the "above" and "below" orientations. The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used herein should be interpreted accordingly.

[0020] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0021] See also Figures 1 to 16 As shown, according to an embodiment of the present invention, a motor is provided, including a front end cover 1, a conductive tape 2, a flexible component 3 and a first support component 4, the front end 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 portion of the front end cover 1 except the front protrusion 5, the flexible component 3 and the first support component 4 are both mounted on the front protrusion 5, and the flexible component 3 is clamped between the first support component 4 and the conductive tape 2.

[0022] In this technical solution, the additional flexible component 3 prevents direct contact between the first support component 4 and the conductive tape 2, effectively preventing damage to the conductive tape 2 during installation. It also secures the conductive tape 2, allowing it to effectively conduct electricity between the front and rear end covers of the motor, eliminating motor shaft voltage and preventing motor corrosion. The flexible component 3 also provides a vibration damping and buffering effect, altering the natural frequencies of the motor body and the first support component 4. This ensures that the natural frequencies of the motor body and the first support component 4 do not substantially coincide within the operating speed range, thereby eliminating resonant noise between the motor body and the first support component 4. The flexible component 3 can be made of a soft material such as silicone rubber or EPDM.

[0023] See also Figure 1 、 Figure 5 and Figure 7As shown, the first support component 4 has a first mounting channel 6, which penetrates the first support component 4 along the height direction of the first support component 4, and a first internal thread 7 is formed on the channel wall of the first mounting channel 6. A first external thread 8 is formed on the outer peripheral wall of the front protrusion 5. The first support component 4 is mounted on the front protrusion 5 through the first mounting channel 6, and the first internal thread 7 is threadedly connected to the first external thread 8.

[0024] In this embodiment, the mounting bracket 23 and the front protrusion 5 of the front end cover 1 are connected by an interference fit in the prior art. This fastening method requires manual pressure, which carries the risk of damaging the mounting bracket 23 due to insufficient pressure. In contrast, the first support member 4 of the present application is connected to the front protrusion 5 of the front end cover 1 by a threaded connection. Compared to an interference fit, this method of installation is simpler and more reliable, requiring only tightening, without the risk of damaging the first support member 4.

[0025] See also Figure 8 and Figure 9 As shown, the first supporting component 4 includes a first main body 41, and the first main body 41 includes an inner ring body 411, an outer ring body 412 and a plurality of connectors 413, one side of each connector 413 is connected to the inner ring body 411, and the other side of each connector 413 is connected to the outer ring body 412, and each connector 413 is distributed circumferentially in the space formed between the inner ring body 411 and the outer ring body 412, and the first internal thread 7 is formed on the inner circumferential wall of the inner ring body 411.

[0026] In this technical solution, by designing the first main body 41 of the first support component 4 to be composed of an inner ring body 411, an outer ring body 412, and a plurality of connectors 413 connecting the inner ring body 411 and the outer ring body 412, the first main body 41 is hollowed to a certain extent while ensuring the structural strength of the first main body 41. This can reduce the weight of the first support component 4 and save material costs. It should be noted that the first support component 4 also includes a first axial extension portion 42 integrally formed on the first main body 41, and the first axial extension portion 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 body 411 and the first axial extension portion 42.

[0027] See also Figure 8 and Figure 9 As shown, a reinforcing rib 414 is connected between two adjacent connectors 413 .

[0028] In this embodiment, the provision 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 support component 4. Each reinforcing rib 414 can be integrally formed between two adjacent connectors 413, forming a circular ring-shaped structure along the circumference of the first main body 41. The first support component 4 can be made of a material with a certain degree of hardness and high temperature resistance, such as PA66.

[0030] In this technical solution, by providing a first waterproof cover 9 covering the end of the first installation channel 6 away from the flexible component 3, external water can be prevented from entering the interior of the motor through the first installation channel 6, thereby providing the motor with a first-level waterproof effect. The material of the first waterproof cover 9 can be a waterproof material such as silicone rubber or EPDM.

[0031] See also Figure 1 As shown, a second support component 10 is assembled on the first support component 4, and the second support component 10 has an accommodating cavity 11 and a second installation channel 12. The first waterproof cover 9 is in the accommodating cavity 11, and one end of the second installation channel 12 leads to the accommodating cavity 11, and the other end of the second installation 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, and the second waterproof cover 13 covers the end of the second installation channel 12 away from the accommodating cavity 11.

[0032] 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 component 4, external water can be prevented from entering the accommodating cavity 11 of the second support component 10 through the second mounting channel 12. Since the first waterproof cover 9 is in the accommodating cavity 11, preventing external water from entering the accommodating cavity 11 can further prevent external water from entering the interior of the motor through the first mounting channel 6 covered by the first waterproof cover 9, thereby making the motor have a secondary waterproof effect, thereby further improving the waterproof ability of the motor. 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. Among them, the material of the second support component 10 can be a material with a certain hardness and high temperature resistance such as PA66, and the material of the second waterproof cover 13 can be a waterproof material such as silicone rubber and EPDM.

[0033] See also Figure 1 、 Figure 7 and Figure 10As shown, a second internal thread 14 is formed on the cavity wall of the accommodating cavity 11, and a second external thread 15 is formed on the outer peripheral wall of the first support component 4. The second support component 10 is mounted on the first support component 4 through the accommodating cavity 11, and the second internal thread 14 is threadedly connected to the second external thread 15.

[0034] In this technical solution, the second support component 10 and the first support component 4 are connected by threads, which makes installation simpler and more reliable, and only requires tightening.

[0035] See also Figure 1 、 Figure 7 and Figure 11 As shown, a drainage channel 16 is configured on the second support component 10 , and the accommodating chamber 11 is communicated with the outside of the second support component 10 through the drainage channel 16 .

[0036] In this embodiment, by providing the drainage channel 16 , water entering the accommodating chamber 11 can be discharged in time.

[0037] The second support component 10 includes a second main body 101 and a second axially extending portion 102 integrally formed on the second main body 101. The second axially extending portion 102 is located on a side of the second main body 101 away from the first support component 4. An accommodating cavity 11 is formed in the second main body 101, and a second mounting channel 12 is formed in the second axially extending portion 102. The motor also includes a front shock-absorbing rubber ring 20, a rear end cover 21, a rear shock-absorbing rubber ring 22, and a rotating shaft 24. The front shock-absorbing rubber ring 20 is mounted on the second axially extending portion 102 of the second support component 10. The rear end cover 21 has a rear protrusion. The conductive tape 2 also covers the rear end cover 21. The rear shock-absorbing rubber ring 22 is mounted on the rear protrusion and secures the conductive tape 2. The rotating shaft 24 passes through the front protrusion 5 of the front end cover 1, the first installation channel 6 of the first support component 4, the first waterproof cover 9, the accommodating cavity 11 of the second support component 10, the second installation channel 12 of the second support component 10, and the second waterproof cover 13 in sequence.

The first positioning structure 17 is positioned and matched with the first positioning matching structure 18 .

[0039] In this technical solution, the alignment and coordination of the first positioning structure 17 and the first positioning and coordination structure 18 makes the alignment and installation between the first support component 4 and the flexible component 3 more convenient and quick. Specifically, the first positioning structure 17 can be a first protrusion formed on the flexible component 3, and the first positioning and coordination 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 alignment and coordination between the first support component 4 and the flexible component 3. Preferably, the cross-section 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.
