[0034] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0035] The seal 130 of the disclosed embodiment is used to cover one end of the motor 120. The seal 130 is a single piece and has a housing 11 for accommodating one end of the motor 120. The seal 130 includes a seal body 1 and a lead portion 3. The housing 11 is provided in the seal body 1. The lead portion 3 is provided at one axial end of the seal body 1 and is used to guide the motor wires and the output terminal.

[0036] Specifically, if Figure 1-Figure 5 As shown, the seal 130 and the motor 120 are arranged sequentially in the left-right direction, with the motor 120 on the left and the seal 130 on the right. The seal body 1 has a housing cavity 11 opening toward the left to enclose the right end of the motor body 1210. The axial direction of the seal body 1 is consistent with the left-right direction. The wire portion 3 is provided on the right end surface of the seal body 1. The wire portion 3 extends rightward along the left-right direction and protrudes rightward from the right end surface of the seal body 1 in the left-right direction.

[0037] Compared with the setting of a cantilever to guide the motor wire in the related art, the seal 130 of the embodiment of the present disclosure provides a wire portion 3 at the end of the sealing body 1 away from the motor 120, so that the wire portion 3 can directly guide the motor wire and the output terminal of the motor 120. Moreover, since the wire portion 3 protrudes from the sealing body 1, it can play a positioning effect when the wire portion 3 is connected to other components, thereby improving the connection accuracy of the seal 130 and other components, and thus improving the sealing reliability.

[0038] Furthermore, compared with the sealing method in the related art in which a first seal is provided on the periphery of the motor 120 and a second seal is provided at the end of the motor 120, this embodiment provides the seal 130 as an integral part and directly covers the right end of the motor 120, which has a simple structure, simplifies the sealing method, and improves assembly efficiency.

[0039] In some embodiments, the wire portion 3 is spaced apart from the outer circumference of the sealing body 1. In other words, the wire portion 3 is provided at one axial end of the sealing body 1, and is not on the outer circumference of the sealing body 1, but is located inside the outer circumference of the sealing body 1. Specifically, as Figure 1-Figure 3 As shown, the lead portion 3 is provided on the right end face of the sealing body 1 and is located inside the outer circumference of the sealing body 1. In this embodiment, by spacing the lead portion 3 from the outer circumference of the sealing body 1, the structure is simple, the strength of the seal is improved, the positioning effect is better, and the sealing reliability is further improved.

[0040] In some embodiments, the sealing body 1 includes an integrated sealing ring 12 and a sealing end plate 13. The sealing end plate 13 is arranged at one axial end of the sealing ring 12 to cover an end face of the motor 120. The wire portion 3 is arranged on the end face of the sealing end plate 13 facing away from the motor 120.

[0041] Specifically, if Figure 3-Figure 5 As shown, the inner circumference of the sealing ring 12 abuts against the outer circumference of the right end of the motor 120, and the sealing ring 12 is used to cover the outer circumference of the right end of the motor 120. The sealing end plate 13 is arranged at the right end of the sealing ring 12, and the wire portion 3 is arranged on the right end surface of the sealing end plate 13. The sealing end plate 13 is used to cover the right end surface of the motor 120. By arranging the sealing ring 12 and the sealing end plate 13, the right end of the motor 120 can be completely covered, thereby improving the sealing reliability of the seal 130.

[0042] In some embodiments, the sealing end plate 13 is provided with a wire hole 131 that passes through the sealing end plate 13 along the axial direction of the sealing ring 12 , and the wire hole 131 and the wire portion 3 are arranged at intervals.

[0043] Specifically, if Figure 3 and Figure 4 As shown, the sealing end plate 13 is provided with a wire hole 131 that passes through the sealing end plate 13 in the left-right direction. The size of the wire hole 131 is larger than the size of the output terminal of the motor 120. The setting of the wire hole 131 facilitates the passage of the motor wires and the output terminals on the motor 120.

[0044] Alternatively, as Figure 1As shown, the pressure cover 140 is provided with a wire groove 1410 that cooperates with the wire portion 3. Since the wire portion 3 and the wire hole 131 are arranged at intervals, the cooperation between the wire portion 3 and the wire groove 1410 facilitates the sealing of the motor wire and reduces noise on the one hand, and on the other hand, the wire portion 3 can also play a positioning role, thereby improving the connection accuracy between the pressure cover 140 and the seal 130.

[0045] In some embodiments, as Figure 5 As shown, the end surface of the sealing end plate 13 facing the motor 120 is provided with a reinforcing rib 4. By providing the reinforcing rib 4 on the left end surface of the sealing end plate 13, the structural strength of the sealing member 130 is improved.

[0046] In some embodiments, the sealing end plate 13 has a center hole 132, and the end surface of the sealing end plate 13 facing away from the motor 120 is provided with a mating portion 5, the mating portion 5 is arranged around the center hole 132, and the end of the mating portion 5 facing away from the motor 120 is closed, and the mating portion 5 is used to pass through the center hole 132 and cooperate with the axial protrusion 1230 of the motor 120.

[0047] Specifically, if Figure 3 and Figure 5 As shown, a mating portion 5 is provided on the right end face of the sealing end plate 13, the right end of the mating portion 5 is closed, and the left end of the mating portion 5 passes through the center hole 132 and cooperates with the protrusion 1230 on the right end face of the motor 120. While the protrusion 1230 of the motor 120 is sealed by the mating portion 5, the coaxial assembly of the seal 130 and the motor 120 can be achieved, thereby improving the assembly accuracy of the seal 130 and the motor 120.

[0048] In some embodiments, the wire portion 3 has a wire cavity 31 extending in a direction away from the motor 120 , and the wire cavity 31 is communicated with the wire hole 131 .

[0049] Specifically, if Figure 3 and Figure 4 As shown, the wire portion 3 extends rightward along the left-right direction and has a wire cavity 31 extending rightward. The connection between the wire hole 131 and the wire cavity 31 facilitates the wire portion 3 to guide the motor wires and the output terminals passing through the wire hole 131.

[0050] In some embodiments, the motor 120 includes a motor body 1210 and a plurality of protrusions 1220 arranged at intervals along the circumference of the motor 120. The protrusions 1220 are provided on the outer circumferential surface of one end of the motor body 1210. The inner circumferential surface of the sealing body 1 is provided with a plurality of accommodating grooves, which accommodate the protrusions 1220. The end of the accommodating groove facing away from the protrusion 1220 is closed so that the seal 130 covers the outer circumferential surface of the protrusion 1220. The plurality of accommodating grooves are arranged at intervals along the circumference of the seal 130, and the plurality of accommodating grooves correspond one-to-one to the plurality of protrusions 1220.

[0051] Specifically, if Figure 1-Figure 5 As shown, the sealing body 1 has a accommodating cavity 11 that opens to the left. The provision of the accommodating cavity 11 facilitates the sealing body 1 to cover the right end of the motor 120. The protrusion 1220 is provided on the outer circumference of the right end of the motor body 1210. The inner circumference of the sealing member 130 is provided with a plurality of accommodating grooves corresponding to the protrusions 1220 to accommodate the protrusions 1220. The ends of the accommodating grooves facing away from the protrusions 1220 are closed so that the walls of the accommodating grooves cover the outer circumference of the protrusions 1220. In this way, the sealing member 130 covers both the motor body 1210 and the protrusions 1220.

[0052] The seal 130 of the embodiment of the present disclosure has a accommodating cavity 11 to cover the motor body 1210. A plurality of accommodating grooves with one end closed away from the protrusion 1220 are provided on the inner circumferential surface of the seal 130 to cover the protrusion 1220 of the motor 120. The sealing structure is simple and can cover the motor body 1210 and the protrusion 1220 at the same time, thereby improving the sealing reliability of the seal 130 in sealing the motor 120.

[0053] In some embodiments, the seal 130 further includes a plurality of sealing protrusions 2 , which are provided on the sealing body 1 , and a receiving groove is provided on the sealing protrusion 2 to cover the outer peripheral surface of the protrusion 1220 , and the plurality of sealing protrusions 2 are arranged at intervals along the circumference of the sealing body 1 .

[0054] Specifically, if Figure 3-Figure 5 As shown, the sealing protrusion 2 is provided on the sealing ring 12 to cover the protrusion 1220, and multiple sealing protrusions 2 are arranged one by one corresponding to the multiple protrusions 1220 on the motor 120. The accommodating groove is provided on the inner circumferential surface of the sealing protrusion 2, and each sealing protrusion 2 covers a corresponding protrusion 1220, so that the sealing body 1 covers the motor 120 while the sealing protrusion 2 covers the protrusion 1220 of the motor 120, thereby improving the sealing reliability of the seal 130.

[0055] Optionally, the sealing protrusion 2 and the sealing body 1 are integrally formed, which improves production efficiency while increasing the connection reliability between the sealing protrusion 2 and the sealing body 1 and enhancing the anti-torque effect of the seal 130 .

[0056] For example, there are three protrusions 1220, which are evenly spaced around the circumference of the motor body 1210. Accordingly, there are three sealing protrusions 2, which are evenly spaced around the circumference of the sealing ring 12 and correspond one-to-one with the three protrusions 1220. When there are two or four protrusions 1220, there are also two or four corresponding sealing protrusions 2.

[0057] In some embodiments, the sealing protrusion 2 includes a first protrusion 21 and a second protrusion 22, the first protrusion 21 is arranged on the outer peripheral surface of the sealing body 1, and the second protrusion 22 is arranged on an axial end face of the sealing body 1, the first protrusion 21 and the second protrusion 22 are connected in sequence in the axial direction of the sealing body 1, and the accommodating groove is arranged on the inner peripheral surface of the second protrusion 22.

[0058] Specifically, if Figure 3-Figure 5 As shown, the first protrusion 21 and the second protrusion 22 are sequentially connected in the left-right direction, which is consistent with the axial direction of the sealing body 1. The first protrusion 21 is located to the right of the second protrusion 22, and the left end of the first protrusion 21 is connected to the right end of the second protrusion 22. The first protrusion 21 is provided on the outer circumferential surface of the sealing body 1, and the second protrusion 22 is provided on the end surface of the left end of the sealing body 1. In other words, the size of the sealing protrusion 2 in the left-right direction is larger than the size of the sealing body 1 in the left-right direction. By protruding the second protrusion 22 to the left of the sealing body 1 in the left-right direction and providing the receiving groove on the inner circumferential surface of the second protrusion 22, it is convenient for the sealing protrusion 2 to cover the protrusion 1220 of the motor 120, and the inner circumferential surface of the sealing protrusion 2 abuts against the outer circumferential surface of the motor body 1210, thereby improving the sealing reliability.

[0059] In some embodiments, the sealing protrusion 2 includes a first protrusion section 23 and a second protrusion section 24, the second protrusion section 24 is arranged at both ends of the first protrusion section 23 in the circumferential direction of the sealing body 1, the first protrusion section 23 has a first groove, the wall of the first groove covers the outer circumferential surface of the protrusion 1220 and the two axial side surfaces of the protrusion 1220 in the sealing body 1, the second protrusion section 24 has a second groove, the wall of the second groove covers the end of the protrusion 1220 in the circumferential direction of the sealing body 1, and the second groove is closed at the end of the sealing body 1 that is away from the protrusion 1220 in the circumferential direction.

[0060] Specifically, if Figure 3-Figure 5 As shown, the first convex section 23 and the second convex section 24 are arranged in sequence in the circumferential direction of the sealing body 1, two second convex sections 24 are provided, the first convex section 23 is provided between the two second convex sections 24, the first groove is arranged with an opening toward the direction of the convex portion 1220, the bottom wall surface of the first groove is used to cover the outer circumferential surface of the convex portion 1220, the left wall surface of the first groove is used to cover the left side surface of the convex portion 1220, and the right wall surface of the first groove is used to cover the right side surface of the convex portion 1220, so that the first convex section 23 covers the outer circumferential surface of the convex portion 1220, the left side surface and the right side surface of the convex portion 1220.

[0061] Since the second protrusions 24 are arranged at both ends of the first protrusion 23 in the circumferential direction of the sealing body 1, the wall of the second groove of one of the two second protrusions 24 covers one end of the protrusion 1220 in the circumferential direction of the sealing body 1, and the wall of the second groove of the other second protrusion 24 covers the other end of the protrusion 1220 in the circumferential direction of the sealing body 1, so that the second protrusions 24 cover the end of the protrusion 1220 in the circumferential direction of the sealing body 1.

[0062] In this embodiment, the outer peripheral surface, left side and right side of the protrusion 1220 are covered by the first protrusion section 23, and the circumferential end of the protrusion 1220 on the sealing body 1 is covered by the second protrusion section 24, so that the sealing protrusion 2 completely covers the protrusion 1220, thereby improving the sealing reliability of the sealing protrusion 2.

[0063] In some embodiments, a notch 25 is provided on the outer peripheral surface of the connection between the second protruding section 24 and the first protruding section 23 .

[0064] It should be noted that the seal 130 is covered on one end of the motor 120, and the outer peripheral surface of the sealing protrusion 2 and the inner peripheral surface of the motor mounting base 110 are interference fit. The assembly of the motor 120 and the motor mounting base 110 is achieved through the setting of the seal 130. The seal 130 has the effect of sealing and shock absorption at the same time.

[0065] Specifically, if Figure 3-Figure 5 As shown, the first convex section 23 and the second convex section 24 are arranged in sequence in the circumferential direction of the sealing body 1, and one end of the first convex section 23 is connected to one end of the second convex section 24. Since the sealing protrusion 2 and the motor mounting seat 110 are interference fit, a groove 25 is provided on the outer peripheral surface of the connection between the first convex section 23 and the second convex section 24 of each sealing protrusion 2, so as to facilitate the assembly of the sealing protrusion 2 in the motor mounting seat 110.

[0066] Optionally, each sealing protrusion 2 is provided with two notches 25 , which penetrate the connection between the first protrusion section 23 and the second protrusion section 24 in the radial direction of the sealing body 1 to reduce the stiffness of the connection between the first protrusion section 23 and the second protrusion section 24 .

[0067] In some embodiments, a first positioning portion 14 is provided on the outer circumference of the sealing body 1 . The first positioning portion 14 is used to cooperate with the second positioning portion 1110 on the motor mounting seat 110 . The first positioning portion 14 is spaced apart from the sealing protrusion 2 .

[0068] Specifically, if Figure 3-Figure 4As shown, the first positioning portion 14 is arranged between two adjacent sealing protrusions 2. By arranging the first positioning portion 14 on the sealing body 1 to cooperate with the second positioning portion 1110 on the motor mounting seat 110, the assembly accuracy of the seal 130 and the motor mounting seat 110 is improved while the anti-torsion effect of the seal 130 is enhanced.

[0069] For example, there are one, two, three, or four first positioning portions 14 . In this embodiment, there are two first positioning portions 14 .

[0070] For example, the first positioning portion 14 is a positioning groove 26 , and the second positioning portion 1110 is a positioning protrusion.

[0071] In some embodiments, the outer circumferential surface of the sealing protrusion 2 is provided with a plurality of grooves 26 extending axially through the sealing protrusion 2 along the sealing body 1. The plurality of grooves 26 are spaced apart circumferentially around the sealing protrusion 2. Providing the plurality of grooves 26 on the sealing protrusion 2 reduces the rigidity of the sealing protrusion 2, facilitating assembly of the sealing protrusion 2 with the motor mounting base 110, and saves material, thereby reducing the cost of the seal 130.

[0072] The motor assembly 100 according to the embodiment of the present disclosure includes a seal 130 according to the embodiment described above.

[0073] Specifically, if Figure 1 As shown, the motor assembly 100 includes a motor mount 110, a motor 120, a seal 130, and a gland 140. The motor 120 is disposed within the motor mount 110. The seal 130 covers one end of the motor 120 and is the seal 130 of the above-described embodiment. At least a portion of the outer circumference of the seal 130 is interference-fitted with the inner circumference of the motor mount 110. The gland 140 abuts against the end of the seal 130 away from the motor 120 and is connected to the motor mount 110.

[0074] The motor assembly 100 of the embodiment of the present disclosure is achieved by wrapping the seal 130 on the motor 120 and assembling it in the motor mounting base 110, and then press-fitting the pressure cover 140 on the seal 130 and assembling it on the motor mounting base 110. Through the interference fit between the outer circumference of the seal 130 and the inner circumference of the motor mounting base 110, on the one hand, the connection between the motor 120 and the motor mounting base 110 is achieved, and the seal 130 has a shock-absorbing effect. On the other hand, the seal 130 can isolate the outside air from entering, preventing air from directly entering the air duct from the gap between the motor 120 and the motor mounting base 110, thereby improving the sealing performance of the motor assembly 100, and simplifying the step of pasting insulation material on the pressure cover 140, thereby improving assembly efficiency.

[0075] The motor assembly 100 of the embodiment of the present disclosure is configured with a wire portion 3 at an end of the sealing body 1 away from the motor 120, so that the wire portion 3 can directly guide the motor wires and output terminals of the motor 120. Moreover, since the wire portion 3 protrudes from the sealing body 1, it can play a positioning effect when the wire portion 3 is connected to other components, thereby improving the connection accuracy of the seal 130 and other components, and thereby improving the sealing reliability.
