[0039] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0040] The following is in conjunction with the appendix Figures 1 to 8 The sealing element 120 of the present disclosure will be described in detail.

[0041] The sealing member 120 of this embodiment is used to cover one end of the motor 10. The sealing member 120 has a receiving cavity 21 for receiving one end of the motor 10. The sealing member 120 has a wire groove 1 at one end away from the motor 10 in the axial direction. The wire groove 1 communicates with the receiving cavity 21. At least a portion of the cross-sectional area of ​​the wire groove 1 gradually decreases in the direction away from the motor 10. The wire groove 1 is used for the motor wire 101 of the motor 10 to pass through.

[0042] The seal 120 of this embodiment has a wire groove 1 at the end away from the motor 10 in the axial direction. By gradually reducing the cross-sectional area of ​​at least a portion of the wire groove 1 in the direction away from the motor 10, the wire space at the end of the wire groove 1 adjacent to the motor 10 is relatively large, which reduces the bending degree of the motor wire 101, thereby reducing the wear between the motor wire 101 and the inner wall surface of the wire groove 1 and improving the service life of the motor wire 101. Moreover, the wire space at the end of the wire groove 1 away from the motor 10 is relatively small, which facilitates the bundling of the motor wire 101 and improves the stability of the motor wire 101.

[0043] Furthermore, since the friction between the seal 120 and the motor wire 101 is small in this embodiment, the friction noise of the motor wire 101 can be reduced, thereby improving the comfort of the air conditioner.

[0044] Specifically, such as Figures 1-3As shown, the seal 120 and the motor 10 are arranged sequentially in the left-right direction. The left end of the receiving cavity 21 of the seal 120 is open to cover the right end of the motor 10. The axial direction of the seal 120 is consistent with the left-right direction. The wire groove 1 is provided at the right end of the seal 120. The wire groove 1 is connected to the receiving cavity 21 to facilitate the motor wire 101 to pass through the wire groove 1.

[0045] Optionally, the cross-sectional area of ​​at least a portion of the wire groove 1 gradually decreases in the direction away from the motor 10, which can be understood as the cross-sectional area of ​​the wire groove 1 gradually decreasing in the direction away from the motor 10; or, the cross-sectional area of ​​a portion of the wire groove 1 gradually decreases in the direction away from the motor 10, while the cross-sectional area of ​​another portion of the wire groove 1 gradually increases or remains constant in the direction away from the motor 10.

[0046] In some embodiments, the seal 120 includes a sealing body 2 and a wire portion 3. The receiving cavity 21 is disposed in the sealing body 2, and the wire portion 3 is disposed at one end of the sealing body 2 away from the motor 10 in the axial direction. The wire groove 1 includes a first groove portion 11 and a second groove portion 12 that are opposite to each other and communicate with each other. The first groove portion 11 is disposed in the sealing body 2, and the second groove portion 12 is disposed in the wire portion 3.

[0047] Specifically, such as Figures 1-3 As shown, the sealing body 2 has a receiving cavity 21 with an open left end to cover the right end of the motor 10. The wire portion 3 is located at the right end of the sealing body 2, extending to the right in the left-right direction, and protruding from the right end face of the sealing body 2. Through the first groove 11 on the sealing body 2 and the second groove 12 on the wire portion 3 that is opposite to and communicates with the first groove 11, the motor wire 101 passes through the first groove 11 and the second groove 12 in sequence. Since the wire portion 3 protrudes from the sealing body 2, it facilitates better guidance of the motor wire 101, and the wire portion 3 can play a positioning role when connected with other components, improving the connection accuracy of the seal 120 with other components.

[0048] In some embodiments, such as Figure 3 As shown, the cross-sectional area of ​​the first groove 11 gradually decreases in the direction toward the second groove 12. By gradually decreasing the cross-sectional area of ​​the first groove 11 from left to right, the wire space at the left end of the first groove 11 is larger than the wire space at the right end of the first groove 11, reducing the degree of bending of the motor wire 101. This allows the motor wire 101 to smoothly enter the first groove 11, reducing wear on the motor wire 101 and increasing its service life.

[0049] In some embodiments, such as Figure 3As shown, the cross-sectional area of ​​at least a portion of the second groove 12 gradually decreases in the direction away from the first groove 11. By gradually decreasing the cross-sectional area of ​​at least a portion of the second groove 12 in the direction from left to right, the wire space at the left end of at least a portion of the second groove 12 is larger than the wire space at the right end of at least a portion of the second groove 12. This facilitates the smooth passage of the motor wire 101 from the first groove 11 through the second groove 12, thereby reducing wear on the motor wire 101 and improving its service life.

[0050] Optionally, the cross-sectional area of ​​the second groove 12 gradually decreases from left to right, or a portion of the cross-sectional area of ​​the second groove 12 gradually decreases from left to right, while the cross-sectional area of ​​another portion of the second groove 12 gradually increases or remains constant from left to right.

[0051] In some embodiments, the second groove 12 includes a first segment 121 and a second segment 122 that are opposite to and connected to each other. The end of the first segment 121 away from the second segment 122 is opposite to and connected to the first groove 11. The cross-sectional area of ​​the first segment 121 gradually decreases in the direction away from the first groove 11, and the cross-sectional area of ​​the second segment 122 is constant in the direction away from the first groove 11.

[0052] Specifically, such as Figure 3 As shown, the first segment 121 and the second segment 122 are arranged sequentially in the left-right direction. The left end of the first segment 121 is connected to the first slot 11, and the right end of the first segment 121 is connected to the second segment 122. That is, the first segment 121 is located between the first slot 11 and the second segment 122. By setting the cross-sectional area of ​​the first segment 121 to gradually decrease from left to right, and setting the cross-sectional area of ​​the second segment 122 to remain constant from left to right, it is convenient for the motor wire 101 to smoothly pass through the first slot 11 through the first segment 121, and it is also convenient for the second segment 122 to bundle the motor wire 101, reducing the relative movement between the motor wires 101 and improving the stability of the motor wires 101.

[0053] In some embodiments, such as Figure 3 As shown, the inner wall surface of the first groove 11 and the inner wall surface of the first segment 121 are coplanar. By setting the inner wall surface of the first groove 11 and the inner wall surface of the first segment 121 to be coplanar, the motor wire 101 smoothly enters the first segment 121 from the first groove 11, further reducing the wear of the motor wire 101.

[0054] In some embodiments, the sealing body 2 includes an integrally formed sealing end plate 22 and a surrounding portion 23. The sealing end plate 22 is disposed at one end of the surrounding portion 23 in the axial direction. The sealing end plate 22 is used to cover one end face of the motor 10. The surrounding portion 23 is used to cover the outer peripheral surface of the motor 10. The wire portion 3 is disposed on the end face of the sealing end plate 22 away from the motor 10.

[0055] Specifically, such as Figure 1 As shown, the axial direction of the surrounding part 23 is consistent with the left and right directions. The sealing end plate 22 is provided at the right end of the surrounding part 23, and the wire part 3 is provided at the right end face of the sealing end plate 22. The sealing end plate 22 is used to cover the right end face of the motor 10. The inner circumferential surface of the surrounding part 23 abuts against the outer circumferential surface of the right end of the motor 10. The surrounding part 23 is used to cover the outer circumferential surface of the right end of the motor 10. Through the arrangement of the surrounding part 23 and the sealing end plate 22, the right end of the motor 10 can be completely covered, improving the sealing reliability of the seal 120.

[0056] In some embodiments, the outer peripheral surface of the seal 120 is provided with an opening 231 that communicates with the receiving cavity 21. The opening 231 is used for the motor wire 101 to pass through the receiving cavity 21. The wire groove 1 is provided with a notch 13 on the outer peripheral surface of the seal 120 to facilitate the entry of the motor wire 101. The notch 13 communicates with the opening 231.

[0057] Specifically, such as Figure 1 and Figure 3 As shown, the motor wire 101 of the motor 10 is led out from the outer peripheral surface of the right end of the motor 10. Since the seal 120 covers the right end of the motor 10, the outer peripheral surface of the surrounding part 23 is provided with an opening 231 opposite to the motor wire 101, which facilitates the motor wire 101 and the output terminal of the motor wire 101 to pass through the receiving cavity 21, thereby facilitating the motor wire 101 to enter the wire groove 1 from the notch 13 on the outer peripheral surface of the wire groove 1, thus improving the output efficiency of the motor wire 101.

[0058] In some embodiments, the seal 120 is a single piece. Compared with the sealing method in the related art, where a first seal 120 is provided on the outer periphery of the motor 10 and a second seal 120 is provided on the end of the motor 10, this embodiment makes the seal 120 a single piece, directly covering the right end of the motor 10. The structure of the seal 120 is simple, the sealing method is simplified, and the assembly efficiency is improved.

[0059] The motor assembly 100 of this disclosure includes a seal 120 employing any of the above embodiments.

[0060] The motor assembly 100 of this embodiment includes the seal 120 of the above embodiment, which can reduce wear on the motor wire 101, increase the service life of the motor wire 101, and thus reduce the frequency of disassembly and assembly of the motor assembly 100.

[0061] In some embodiments, the motor assembly 100 further includes a motor mounting base 110, which has a chamber 111 for mounting the motor 10. The outer peripheral surface of the motor mounting base 110 is provided with a first positioning part 112, which is used to be inserted into a second positioning part 201 on the base 20.

[0062] Specifically, such as Figures 4-6 As shown, the motor mounting base 110 is installed at one end of the base 20 in the left-right direction. The motor mounting base 110 can be installed at the left end of the base 20, or at the right end of the base 20, or at both the left and right ends of the base 20. In this embodiment, the motor mounting base 110 is installed at the right end of the base 20.

[0063] The motor mounting base 110 has a chamber 111 that extends through the motor mounting base 110 in the left-right direction. The motor 10 is installed in the chamber 111. The seal 120 is located at the right end of the motor 10 and covers the right end of the motor 10. The motor mounting base 110 is installed on the base 20. The base 20 is provided with a second positioning part 201.

[0064] The first positioning part 112 is provided on the outer peripheral surface of the motor mounting base 110. The first positioning part 112 extends in the radial direction away from the motor mounting base 110. The first positioning part 112 is inserted into the second positioning part 201. On the one hand, it can restrict the movement of the motor mounting base 110 in the radial direction of the motor mounting base 110. On the other hand, it can achieve a sealing effect to prevent air leakage and condensation in the air duct of the air conditioner.

[0065] Optionally, a sealing element 120, such as a sealing sponge, is provided between the first positioning part 112 and the second positioning part 201 to further improve the sealing performance between the motor mounting base 110 and the base 20.

[0066] Optionally, the first positioning part 112 is a pin, and the second positioning part 201 is a socket.

[0067] In some embodiments, the motor mounting base 110 includes a mounting base body 113 and a contoured portion 114. The contoured portion 114 is disposed on the outer peripheral surface of the mounting base body 113. The outer peripheral surface of the contoured portion 114 is in close contact with the inner surface of the mounting portion 202 of the base 20. The outer peripheral surface of the contoured portion 114 is provided with a protrusion 115. The protrusion 115 is used to stop against the baffle 203 on the base 20 in the axial direction of the mounting base body 113. The first positioning portion 112 is connected to the contoured portion 114 and is spaced apart from the protrusion 115 in the circumferential direction of the mounting base body 113.

[0068] Specifically, such as Figures 4-8As shown, the right end of the base 20 is provided with a mounting part 202, which cooperates with the motor mounting seat 110. The outer peripheral surface of the mounting seat body 113 is provided with a contouring part 114, which extends in a direction away from the mounting seat body 113, that is, the contouring part 114 protrudes radially from the mounting seat body 113. The first positioning part 112 is connected to the contouring part 114 and extends radially away from the contouring part 114 of the mounting seat body 113. The inner peripheral surface of the contouring part 114 is connected to the outer peripheral surface of the mounting seat body 113. The outer peripheral surface of the contouring part 114 is in close contact with the inner surface of the mounting part 202 of the base 20. The first positioning part 112 is inserted into the second positioning part 201 on the base 20, so that the connection between the motor mounting seat 110 and the base 20 is in close contact, preventing air from passing through the connection between the motor mounting seat 110 and the base 20, improving the compatibility between the motor mounting seat 110 and the base 20 while improving the sealing performance.

[0069] The contour part 114 and the baffle 203 on the base 20 are arranged sequentially in the left and right directions. The left end face of the protrusion 115 abuts against the right end face of the baffle 203, restricting the movement of the mounting body 113 to the left in the left and right directions, thereby improving the stability of the motor mounting base 110.

[0070] Optionally, by aligning the end of the protrusion 115 in the circumferential direction of the mounting body 113 with the end of the baffle 203, the accurate installation of the motor mounting base 110 can be ensured, and the fit between the mounting body 113 and the base 20 can be improved.

[0071] In some embodiments, the motor assembly 100 further includes a third positioning part 116, which is disposed on the outer peripheral surface of the mounting base body 113. The third positioning part 116 and the first positioning part 112 are arranged axially spaced apart in the mounting base body 113. The third positioning part 116 is used to insert into a fourth positioning part on the base 20.

[0072] Specifically, such as Figures 4-8 As shown, the third positioning part 116 is provided on the outer peripheral surface of the mounting base body 113. The third positioning part 116 extends in the radial direction away from the mounting base body 113. The third positioning part 116 is located to the right of the first positioning part 112. The third positioning part 116 is inserted into the fourth positioning part to further restrict the movement of the motor mounting base 110 in the radial direction and improve the stability of the motor mounting base 110.

[0073] Optionally, there are multiple third positioning parts 116, which are arranged at intervals along the circumference of the mounting body 113. There are also multiple fourth positioning parts, with each of the multiple third positioning parts 116 corresponding to one of the multiple fourth positioning parts. The arrangement of multiple third positioning parts 116 can position the mounting position of the mounting body 113 while also providing installation guidance.

[0074] Optionally, the third positioning part 116 is a pin, and the fourth positioning part is a socket.

[0075] In some embodiments, the base 20 is further provided with a stop 204, the stop 204 and the baffle 203 are arranged axially on the mounting body 113, and the stop 204 abuts against the end face of one end of the motor mounting base 110 in the axial direction.

[0076] Specifically, such as Figures 6-8 As shown, the motor mounting base 110 is located at the left end of the stop portion 204. That is, the right end face of the motor mounting base 110 abuts against the left end face of the stop portion 204. By providing the stop portion 204 on the base 20, the movement of the motor mounting base 110 to the right is restricted, thereby improving the stability of the motor mounting base 110.

[0077] Optionally, the stop portion 204 includes a base plate 2041 and a rib 2042. The base plate 2041 is located on one side of the motor mounting base 110 in the axial direction. The rib 2042 is provided at one end of the base plate 2041 facing the motor mounting base 110, and the rib 2042 abuts against the end face of the motor mounting base 110. The rib 2042 is located on the left side of the base plate 2041, protruding to the left from the base plate 2041. The rib 2042 extends in the vertical direction. By providing the rib 2042 on the base plate 2041 and making the left end face of the rib 2042 abut against the right end face of the cover, it is convenient to install the motor mounting base 110 while restricting the rightward movement of the motor mounting base 110.

[0078] Optionally, the upper end of the rib 2042 is chamfered to facilitate the installation of the motor mounting base 110.
