DETAILED DESCRIPTION

[0018] 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.

[0019] 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.

[0020] For ease of description, spatially relative terms such as "on," "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" the other devices or features would then be positioned "below" or "beneath" the other devices or features.

[0021] See also Figures 1 to 5 As shown, according to an embodiment of the present invention, a wire outlet structure is provided, which includes an end cover 1, a plastic sealing member 2 and a wire outlet assembly 3; the plastic sealing member 2 has a first mounting end 201, the end cover 1 has a second mounting end 101, the first mounting end 201 is assembled with the second mounting end 101, and an assembly gap is provided between the first mounting end 201 and the second mounting end 101; the wire outlet assembly 3 includes a sealing ring 4 and a wire outlet sheath 5, the wire outlet sheath 5 has a wire outlet port 501, and a sealing ring 4 is provided on the side of the wire outlet sheath 5 facing away from the wire outlet port 501, an outer edge of the first mounting end 201 or an outer circle of the second mounting end 101 is provided with a mounting groove 211, the wire outlet sheath 5 is installed in the mounting groove 211, and the sealing ring 4 fills the assembly gap.

[0022] Specifically, a mounting groove 211 is pre-formed on the outer edge of the first mounting end 201 or the outer edge of the second mounting end 101. The wiring harness is passed through the outlet sheath 5. The outlet sheath 5 is aligned with the position of the mounting groove 211 and then installed in the mounting groove 211. Ensure that the outlet sheath 5 is firmly installed and positioned accurately, and that the direction of its outlet port 501 meets the setting requirements. Align the first mounting end 201 of the plastic package 2 with the second mounting end 101 of the end cover 1, and assemble the two. During the assembly process, maintain the coaxiality and verticality of the two. After installation, the sealing ring 4 can completely fill the assembly gap between the first mounting end 201 and the second mounting end 101, and lead the wires inside the motor out from the outlet port 501 of the outlet sheath 5.

[0023] It is worth noting that the sealing ring 4 is preferably sleeved on the outer peripheral wall of the first mounting end 201 or the outer peripheral wall of the second mounting end 101. After the end cover 1 and the plastic package 2 are assembled, the sealing ring 4 can fill the assembly gap.

[0024] In this embodiment, under high-requirement waterproof conditions, the sealing ring 4 fills the assembly gap between the first mounting end 201 of the plastic package 2 and the second mounting end 101 of the end cap 1. When external water flows into the motor, the elastic material of the sealing ring 4 enables it to fit tightly against the inner wall of the assembly gap, forming a waterproof barrier that prevents water from entering the motor. This effectively protects the internal components of the motor from water erosion, avoids short circuits, corrosion, and other faults caused by water ingress, and ensures the normal operation of the motor in harsh environments such as humidity or splashing water. The wiring harness is threaded into the outlet sheath 5, which is installed in the mounting groove 211, and the sealing ring 4 is located on the side of the outlet sheath 5 facing away from the outlet port 501. The sealing ring 4 can provide a certain sealing and fixing effect on the wiring harness, preventing the wiring harness from shaking and displacement during motor operation, reducing the possibility of the wiring harness being damaged by friction with surrounding components, and also helping to maintain the sealing performance at the outlet port 501, preventing foreign matter from invading the motor interior through the outlet port 501.

[0025] In this embodiment, a sealing ring 4 fills the assembly gap between the first mounting end 201 of the plastic package 2 and the second mounting end 101 of the end cap 1, effectively preventing foreign matter such as moisture and dust from entering the interior of the motor through the assembly gap. The outlet sheath 5 is installed in the installation groove 211, enclosing the wiring harness therein, isolating the wiring harness outlet position from the external environment and preventing foreign matter from invading from the periphery of the outlet port 501. Together, the two components form a comprehensive sealing protection system for the motor outlet area, significantly improving the motor's protection capabilities in harsh environments and meeting high protection level requirements. The provision of the sealing ring 4 and the installation of the outlet sheath 5 in the installation groove 211 work together. Even if a small gap or looseness occurs in one of them due to unexpected circumstances (such as minor bumps, long-term vibration, etc.), the other component can play a certain compensatory role, maintaining the overall sealing protection effect, improving the reliability and stability of the motor's protection performance, and reducing the risk of motor failure due to sealing failure. The wire outlet sheath 5 is installed in the installation groove 211, which plays a role in positioning and supporting the wire outlet 501, making the wire harness outlet position more stable; the sealing ring 4 not only fills the assembly gap, but also plays a buffering and filling role, making the assembly between the plastic package 2 and the end cover 1 tighter and more stable. The two together enhance the overall stability of the motor outlet structure, reduce the problems of wire harness shaking and component loosening caused by factors such as vibration and impact during the operation of the motor, and improve the reliability of the motor operation. The wire outlet sheath 5 provides a neat and orderly wire outlet channel for the wire harness, which facilitates the connection and arrangement of the internal wire harness of the motor with the external power line and load line; at the same time, its synergistic sealing effect with the sealing ring 4 makes the wire harness connection part in a relatively clean and stable environment, which is conducive to subsequent maintenance and inspection work, and improves the maintainability of the motor.

[0026] See also Figures 1 to 5 As shown, the outer edge of the first mounting end 201 is provided with a mounting groove 211, the sealing ring 4 is sleeved on the outer peripheral wall of the first mounting end 201, and the inner peripheral wall of the second mounting end 101 is pressed against the sealing ring 4 so that the sealing ring 4 fills the assembly gap.

[0027] Specifically, the wiring harness is passed through the outlet sheath 5, and after aligning the position at the installation groove 211 pre-opened on the outer edge of the first mounting end 201, the outlet sheath 5 with the wiring harness is embedded in the installation groove 211, and the sealing ring 4 is placed on the outer peripheral wall of the first mounting end 201. It is necessary to pay attention to the correct installation position of the sealing ring 4 to ensure that it can completely cover the position of the subsequent assembly gap. The second mounting end 101 of the end cover 1 is aligned with the first mounting end 201 of the plastic package 2, and the coaxiality and verticality of the two are maintained to ensure the accuracy and sealing of the assembly. The second mounting end 101 of the end cover 1 is pressed toward the first mounting end 201, so that the inner peripheral wall of the second mounting end 101 gradually presses the sealing ring 4. After the end cover 1 and the plastic package 2 are assembled, the wires inside the motor are led out from the outlet 501 of the outlet sheath 5.

[0028] In this embodiment, the shape and size of the mounting groove 211 match the outlet sheath 5, providing a precise mounting position for the outlet sheath 5, ensuring that the outlet sheath 5 can be accurately installed in the predetermined position, and ensuring that the direction and position of the outlet port 501 meet the setting requirements. After the outlet sheath 5 is embedded in the mounting groove 211, it is tightly combined with the first mounting end 201, enhancing the installation stability of the outlet sheath 5, preventing the outlet sheath 5 from loosening or shifting due to factors such as vibration and impact during the operation of the motor, thereby ensuring the stability of the wiring harness. The setting of the mounting groove 211 provides convenient conditions for the installation of the sealing ring 4. The sealing ring 4 can be more accurately mounted on the outer peripheral wall of the first mounting end 201, and when the second mounting end 101 of the end cover 1 presses the sealing ring 4, the mounting groove 211 can help the sealing ring 4 better fill the assembly gap, ensuring the reliability of the sealing effect. In conjunction with the sealing ring 4, the mounting groove 211 makes the sealing performance of the entire outlet structure more perfect. The wire sheath 5 is installed in the groove to wrap the wire harness, reducing the channel for external moisture, dust and other foreign matter to invade the interior of the motor from the periphery of the wire outlet 501. Together with the sealing ring 4, it constructs a comprehensive sealing protection system, effectively improving the waterproof and dustproof capabilities of the motor and meeting the requirements of a high protection level.

[0029] In this embodiment, the sealing ring 4, through sleeve installation and press-fitting, fully fills the assembly gap between the first mounting end 201 and the second mounting end 101, achieving a tight fit and effectively preventing external foreign matter such as moisture and dust from entering the motor interior, thus meeting high-level protection requirements. The press-fitting process deforms the sealing ring 4, generating radial force that squeezes the first mounting end 201 and the second mounting end 101 tightly together, enhancing the tightness of the assembly, reducing the possibility of loosening, and improving the overall stability of the motor's wiring structure.

[0030] See also Figures 1 to 5As shown, the outlet sheath 5 includes an outlet sheath body 51, a connecting boss 52 and a support member 53 connected in sequence. The end of the sheath body 51 away from the connecting boss 52 has an outlet port 501, and the end of the sheath body 51 away from the connecting boss 52 extends out of the plastic package 2; the connecting boss 52 is installed in the installation groove 211, the sealing ring 4 is connected to the connecting boss 52, and the support member 53 is located on the radial inner side of the sealing ring 4 and is inlaid with the plastic package 2.

[0031] Specifically, the support member 53 is embedded in a predetermined position inside the plastic encapsulation 2, ensuring that the support member 53 and the plastic encapsulation 2 are tightly fitted together. The support member 53 and the plastic encapsulation 2 are firmly embedded together, ensuring that the support member 53 does not loosen or shift during the operation of the motor, thereby providing stable support for the outlet sheath 5. The wiring harness inside the motor is passed through the support member 53, and then through the connecting boss 52 and the sheath body 51 in sequence. The outlet sheath 5 with the wiring harness is aligned with the mounting groove 211 of the first mounting end 201, and the connecting boss 52 is accurately inserted into the mounting groove 211. During installation, it is necessary to ensure that the shape and size of the connecting boss 52 and the mounting groove 211 match to achieve a tight fit. The sealing ring 4 is placed on the outer peripheral wall of the first mounting end 201, and the second mounting end 101 of the end cap 1 is aligned with the first mounting end 201 of the plastic encapsulation 2, maintaining the coaxiality and perpendicularity of the two. Press the second mounting end 101 of the end cap 1 toward the first mounting end 201, gradually pressing the inner wall of the second mounting end 101 against the sealing ring 4 until the sealing ring 4 completely fills the assembly gap between the first mounting end 201 and the second mounting end 101, creating a reliable seal. Once the end cap 1 and the plastic encapsulation 2 are assembled, lead the wires from the motor through the outlet 501 of the outlet sheath 5.

[0032] In this embodiment, by embedding the support member 53 into a predetermined position inside the plastic encapsulation member 2 and closely fitting and firmly embedding it with the plastic encapsulation member 2, a stable basic support is provided for the outlet sheath 5. This ensures that the outlet sheath 5 will not become loose or shifted due to factors such as vibration and impact during the operation of the motor, ensuring the installation stability of the outlet sheath 5, thereby improving the reliability of the motor outlet structure. The wiring harness inside the motor is passed through the support member 53, passing through the connecting boss 52 and the sheath body 51 in sequence, and then the outlet sheath 5 with the wiring harness is aligned with the installation groove 211 of the first mounting end 201, and the connecting boss 52 is accurately inserted into the installation groove 211. This arrangement ensures the precise installation and close fit between the outlet sheath 5 and the plastic encapsulation member 2, avoids problems such as skewness and misalignment of the outlet sheath 5 that may occur during installation, and improves the accuracy and quality of assembly.

[0033] In this embodiment, the outlet sheath body 51 serves as the main body of the outlet sheath 5, directly wrapping and protecting the wiring harness inside the motor, preventing the wiring harness from being damaged by external mechanical means such as friction and collision during motor operation. It also serves as an insulator to prevent short circuits between the wiring harnesses or between the wiring harnesses and other motor components. The connecting boss 52 connects the outlet sheath body 51 with the support member 53 to form a complete protective channel, ensuring that the wiring harness can be smoothly led from the inside of the motor to the outside. At the same time, the support member 53 provides support for the entire outlet sheath 5, maintaining a stable position and shape, further enhancing the protective effect of the wiring harness. The connecting boss 52, in conjunction with the mounting groove 211, secures the outlet sheath 5 to the plastic package 2, ensuring that the outlet sheath 5 will not loosen or shift during motor operation, thereby ensuring the stability of the wiring harness output. The outlet sheath body 51, the connecting boss 52, and the support member 53 are connected sequentially, resulting in a simple and compact structure that is easy to disassemble and assemble. When the motor needs to be maintained or the wiring harness needs to be replaced, the outlet sheath 5 can be quickly removed from the plastic package 2 to perform corresponding maintenance operations, thereby improving the maintainability of the motor.

[0034] See also Figures 1 to 5 As shown, one end of the outlet sheath 5 faces the plastic package 2, and the other end of the outlet sheath 5 has an outlet port 501. A first protrusion 401 is provided on the sealing ring 4, and the first protrusion 401 is embedded and matched with the outlet sheath 5, that is, the first protrusion 401 is embedded and matched with the connecting boss 52.

[0035] Specifically, the first protrusion 401 is inlaid and matched with the connecting boss 52, and then the support member 53 is embedded in a predetermined position inside the plastic package 2 to ensure that the support member 53 and the plastic package 2 are tightly matched and firmly inlaid together, and the connecting boss 52 is accurately inserted into the installation groove 211 to ensure a tight fit between the outlet sheath 5 and the plastic package 2.

[0036] In this embodiment, the first protrusion 401 is embedded in the connecting boss 52, creating a tighter fit between the sealing ring 4 and the connecting boss 52. This tight fit further reduces the gap between the sealing ring 4 and the connecting boss 52, effectively preventing external foreign matter such as moisture, dust, and other foreign matter from entering the motor interior through the gap between the connecting boss 52 and the sealing ring 4, thereby enhancing sealing performance. Combined with the sealing method in which the sealing ring 4 fills the assembly gap, a multi-layer sealing protection is formed. Even if a certain layer of sealing develops minor flaws or deteriorates due to long-term use, the sealing in the other layers can still provide a certain barrier, greatly improving the overall sealing reliability of the motor's wire outlet area and ensuring long-term stable operation of the motor in harsh environments. The embedded fit of the first protrusion 401 and the connecting boss 52 provides a precise positioning and fixing method for the sealing ring 4. During assembly, the first protrusion 401 can accurately fit into the corresponding position of the connecting boss 52, ensuring that the sealing ring 4 is accurately positioned after assembly and prevents it from shifting or falling off, thereby ensuring the stability of the sealing effect. The cooperation between first protrusion 401 and connecting boss 52 integrates the function of sealing ring 4 with the structure of connecting boss 52, allowing the components to cooperate and support each other, forming an organic whole. This not only improves the functional coordination of the components, but also enhances the systematicness and integrity of the entire output structure, allowing it to better play its role in protecting the internal components of the motor.

[0037] See also Figures 1 to 7 As shown, the first protrusion 401 is arranged radially inwardly of the sealing ring 4, that is, the arrangement direction of the first protrusion 401 is flush with the width direction of the sealing ring 4. From the radial inward side of the outlet sheath 5 as a reference, the first protrusion 401 is embedded in the side wall of the connecting boss 52 from the side. A step gap 502 is formed between the first protrusion 401 and the outlet sheath 5, and the outer peripheral wall of the second mounting end 101 is embedded in the step gap 502.

[0038] Specifically, the first protrusion 401 on the sealing ring 4 is embedded into the side wall of the connecting boss 52 from the radially inner side of the outlet sheath 5. The setting direction of the first protrusion 401 is flush with the width direction of the sealing ring 4, ensuring that the first protrusion 401 is tightly coupled with the side wall of the connecting boss 52 and forming a step gap 502 between the first protrusion 401 and the outlet sheath 5. This step gap 502 will be used to accommodate the outer peripheral wall of the second mounting end 101. The second mounting end 101 of the end cap 1 is aligned with the first mounting end 201 of the plastic package 2, and the second mounting end 101 of the end cap 1 is pressed toward the first mounting end 201, so that the outer peripheral wall of the second mounting end 101 gradually fits into the step gap 502 formed between the first protrusion 401 and the outlet sheath 5. At this time, when viewed from the outside, the entire sheath body 51 has no gap between the sheath body 51 and the end cap 1 and the plastic package 2.

[0039] In this embodiment, the first protrusion 401 tightly fits against the sidewall of the connecting boss 52, forming a primary sealing barrier that prevents moisture and dust from entering the motor interior through the gap between the connecting boss 52 and the sealing ring 4. Simultaneously, the outer peripheral wall of the second mounting end 101 nestles within the step gap 502, further enhancing the sealing effect and forming a secondary sealing barrier that effectively prevents foreign matter from entering the motor interior through the assembly gap. The first protrusion 401, embedded in the sidewall of the connecting boss 52, provides precise positioning for the sealing ring 4, ensuring that the sealing ring 4 does not shift or tilt during assembly, thereby ensuring uniform and reliable sealing. The outer peripheral wall of the second mounting end 101 nestles within the step gap 502, limiting radial and axial movement of the sealing ring 4 and the outlet cable sheath 5, enhancing the stability of the entire outlet cable structure and ensuring that all components maintain their correct positional relationship during motor operation. Through multiple seals and a tight fit, moisture, dust, insects, and other foreign matter are effectively prevented from entering the motor interior through the outlet cable, improving the motor's protection level and meeting the requirements for use in harsh environments.

[0040] As a specific implementation method, refer to Figure 6 As shown, the sealing ring 4 and the first protrusion 401 are made of flexible silicone material, and the sleeve body 51 is also made of flexible silicone material. The soft silicone material effectively fills the gap between the end cover and the plastic sealing part 2, which is more conducive to the assembly gap between the end cover 1 and the plastic sealing part 2 and the sealing at the installation groove 211. Since the first protrusion 401 and the sleeve body 51 are all inlaid and matched with the connecting boss 52, the preferred method in this embodiment is that the sealing ring 4 and the sleeve body 51 are first integrally formed or inlaid together. Since the first protrusion 401 is arranged on the radial inner side of the sealing ring 4, the central axis of the first protrusion 401 is perpendicular to the central axis of the sleeve body 51, which can ensure that the first protrusion 401 is connected to the side wall of the connecting boss 52, and the sleeve body 51 is connected to the other side wall of the connecting boss 52, that is, the first protrusion 401 and the sleeve body 51 are respectively installed on the connecting boss 52 from two directions. The connecting boss 52 and the supporting member 53 not only connect the sheath body 51 and the sealing ring 4 , but also are installed in the plastic package 2 . Therefore, the connecting boss 52 and the supporting member 53 are made of a harder nylon material.

[0041] As a specific implementation, a deformation groove is provided in the first protrusion 401 , and a connecting column is provided on the side wall of the connecting boss 52 , and the connecting column is interference-fitted in the deformation groove.

[0042] See also Figures 1 to 5 As shown, the support member 53 has a wire hole 531, and a wire harness channel is opened in the wire outlet sheath 5. One end of the wire harness channel passes through the support member 53 and is connected to the wire hole 531, and the other end of the wire harness channel passes through the connecting boss 52 and the sheath body 51 in sequence.

[0043] In this embodiment, starting from the wire hole 531 of the support member 53, the wire harness channel passes through the connecting boss 52 and the sheath body 51, providing a continuous and smooth wire outlet path for the internal wire harness of the motor, ensuring that the wire harness can be smoothly led out from the inside of the motor to the outside. The wire harness channel prevents the wire harness from direct contact with other components inside the motor during the wire outlet process, reducing the risk of mechanical damage such as friction and pulling, and at the same time plays a certain insulating protection role to prevent the wire harness from short-circuiting. The wire hole 531 of the support member 53 and the wire harness channel of the outlet sheath 5 work together to provide a stable support for the wire harness, prevent the wire harness from shaking or shifting during the operation of the motor, and ensure the stability of the outlet. The connecting structure between the support member 53 and the outlet sheath 5 enhances the synergistic effect between the two, making the entire outlet structure more compact and stable, and improving the overall structural strength of the motor outlet part. The connection setting of the wiring harness channel enables the sealing ring 4 and other sealing components to surround the wiring harness more tightly, enhancing the sealing effect and preventing foreign matter such as moisture and dust from invading the interior of the motor from around the wiring harness. This setting reduces the risk of failure caused by loose wiring harness, wear or poor sealing, and improves the reliability and durability of the motor under various working conditions.

[0044] See also Figures 1 to 5 As shown, a wire leakage groove 532 is formed on the inner wall of the wire through hole 531 , and the wire harness is bent out of the wire leakage groove 532 .

[0045] In this embodiment, the wire through hole 531 refers to the hole from which the wire harness extends outward to the entire machine under normal use, and the wire leakage groove 532 refers to the hole in the assembled state (wire harness welding state) where the front end of the wire harness can be folded downward to increase the unrestricted length of the wire harness, which is equivalent to increasing the length of the bare wire. Welding requires a longer wire length for ease of welding.

[0046] See also Figures 1 to 5 As shown, the end surface of the support member 53 facing away from the connecting boss 52 is provided with two wire passing grooves 533 , and the two wire passing grooves 533 are respectively located on both sides of the wire through hole 531 .

[0047] In this embodiment, the two wire grooves 533 are located on both sides of the wire hole 531, respectively, so that the wire harness can be reasonably distributed to the wire grooves 533 on both sides, avoiding excessive concentration of the wire harness at the wire hole 531, making the layout of the wire harness at the end face of the support member 53 more uniform and neat, and reducing mutual interference between the wire harnesses. When there are multiple wire harnesses inside the motor that need to be led out, this setting can meet the wire outlet requirements of multiple wire harnesses, provide an independent wire outlet channel for each wire harness, ensure separation and insulation between the wire harnesses, and avoid problems such as short circuits caused by crossing or overlapping wire harnesses. The wire grooves 533 provide clear wire outlet direction guidance for the wire harness, so that the wire harness can be more smoothly led out of the wire hole 531 of the support member 53 to the outside, facilitating subsequent assembly and connection operations and improving assembly efficiency. The wire harness is distributed in the wire grooves 533 on both sides, which can reduce the gap between the wire harness and the support member 53, reduce the risk of external moisture, dust and other foreign matter invading the interior of the motor from around the wire harness, and enhance the sealing performance of the motor outlet.

[0048] See also Figures 1 to 5 As shown, both ends of the support member 53 are bent in the circumferential direction of the plastic sealing member 2 so that the side walls of the support member 53 are embedded and matched with the plastic sealing member 2. The support member 53 is used to seal the gap between the plastic sealing member 2 and the sheath body 51.

[0049] In this embodiment, the two ends of the support member 53 are bent in the circumferential direction of the plastic seal 2, so that its side walls are tightly embedded in the plastic seal 2, which can effectively fill and seal the gap between the plastic seal 2 and the sheath body 51, preventing external moisture, dust, particulate matter and other foreign matter from entering the interior of the motor through this gap, thereby improving the protection level of the motor, enhancing its sealing performance in harsh environments, and ensuring the normal operation of the internal components of the motor. Together with other sealing components such as the sealing ring 4, they form a complete sealing system for the motor outlet, making the sealing effect of the motor more reliable and further reducing the risk of motor failure due to poor sealing. After the curved portion of the support member 53 is embedded in the plastic seal 2, a more stable support structure is formed, providing more reliable support for the sheath body 51, enhancing the mechanical strength and stability of the entire outlet structure, enabling it to better resist external forces such as vibration and impact generated during the operation of the motor, and reducing the possibility of loosening or damage to the outlet components. The curved portion of support member 53, inlaid with plastic encapsulation 2, provides more precise positioning and guidance for the installation of sheath body 51, ensuring accurate alignment and fixation of sheath body 51 with plastic encapsulation 2 during assembly. This improves assembly precision and quality and reduces the impact of assembly errors. The tight integration of support member 53 and plastic encapsulation 2 prevents direct friction and collision between the wiring harness and plastic encapsulation 2, reducing wear and tear on the wiring harness during motor operation, extending its service life, and reducing the risk of motor failure due to wiring harness damage.

[0050] As a specific embodiment, a connecting column is provided on the end face of the connecting boss 52 facing away from the support member 53, and a groove is provided on the sleeve body 51, and the connecting column is interference fit in the groove, that is, the sleeve body 51 and the connecting boss 52 are inlaid and matched, while the support member 53 and the connecting boss 52 are integrally formed, and the installation positions and shapes of the two are different.

[0051] As a specific embodiment, a plurality of snap-fit ​​parts are provided on the circumferential direction of the end cover 1, and a plurality of snap-fit ​​grooves are provided on the circumferential direction of the plastic sealing part 2. When the end cover 1 is pressed onto the plastic sealing part 2, the snap-fit ​​parts are clamped in the snap-fit ​​grooves to form another locking structure.

[0052] A motor includes an outgoing wire structure, wherein the outgoing wire structure is the above-mentioned outgoing wire structure.
