Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electric machines, and particularly relates to a wire outlet structure and an electric machine. BACKGROUND

[0002] With the energy efficiency upgrade of various household appliances, the market of high-energy-efficiency DC brushless electric machines is rapidly growing. When the controller of a DC brushless electric machine is integrated in the electric machine, the waterproof requirement for the electric machine is higher. The traditional elastic wire outlet rubber nozzle relies on the elastic force of the rubber itself to contact the end cover and is not locked by external force, so the waterproof capability is limited. In order to improve the quality of the electric machine, household appliance electric machines with high waterproof performance are increasingly popular in the market. In order to achieve good waterproof effect, a waterproof connector is used for the electric machine lead-out wire. The conventional waterproof connector is a separate piece and is screwed onto the outer wall hole of an end cover. Such a structure is relatively complex and requires two seals: 1) an elastic seal between the waterproof connector and the end cover; and 2) an elastic seal between the waterproof connector and the power cord.

[0003] When the electric machine has a built-in controller, one end of the power cord of the electric machine is connected to the controller, and the other end is inserted into a connector. Because the size of the connector is large, the waterproof connector cannot pass through. Currently, there are two processes: 1) the power cord is first connected to the connector, then the waterproof connector is sleeved, and then the power cord is welded to the controller. Because the power cord has the waterproof connector, it is difficult to automatically wave solder the power cord to the controller and manual welding is required, which is low in production efficiency. 2) the power cord is first welded to the controller, then the waterproof connector is sleeved, and then the terminal is inserted into the connector. Because static electricity is easily generated during the terminal crimping process, the controller is easily damaged. SUMMARY

DETAILED DESCRIPTION

[0037] Clearly, the embodiments described are only a part of all the embodiments of the present application, rather than all the embodiments. The description of the at least one example embodiment is actually only illustrative in nature and by no means as any limitation to the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0039] For the convenience of description, spatial relative terms such as "over", "above", "upper surface", "upper" and the like can be used to describe the spatial position relationship of one device or feature with other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawings. For example, if the device in the drawings is inverted, the device described as "above" or "over" other devices or structures will be positioned "below" or "under" other devices or structures.

[0040] For reference Figures 1 to 16 As shown, according to the embodiments of the present application, a wire outlet structure is provided, which comprises a shell 1, a joint assembly 2; the shell 1 is provided with a mounting through hole 101, and the joint assembly 2 is arranged at the mounting through hole 101; the joint assembly 2 comprises a fixing ring 201 and a sleeve ring 202, the fixing ring 201 is mounted on the outer wall of the shell 1, and the fixing ring 201 is provided with a wire outlet through hole 211; the sleeve ring 202 is provided with a lead-out wire 3, and the sleeve ring 202 is embedded in the wire outlet through hole 211; the fixing ring 201 is extruded to deform the sleeve ring 202 under the action of external force, so that the sleeve ring 202 covers the lead-out wire 3.

[0041] Specifically, the lead-out wire 3 is threaded through the mounting hole 101 of the shell 1 to pass the lead-out wire 3 of the motor from the inside of the motor to the outside of the shell 1, the collar 202 is embedded into the lead-out hole 211 of the fixing ring 201, and the outer wall of the collar 202 is in contact with the inner wall of the lead-out hole 211 of the fixing ring 201. An external force is applied to the fixing ring 201 which has been fixed on the shell 1 in the radial direction inward, and this external force can be a radial pressure applied by a special tool or component, so that the fixing ring 201 is tightened inward in the radial direction. As the fixing ring 201 is tightened, the diameter of the lead-out hole 211 thereof gradually decreases, thereby extruding the collar 202 to cause the deformation of the collar 202. In the process of deformation of the collar 202, the inner wall of the collar 202 tightly adheres to the outer wall of the lead-out wire 3, thereby realizing the tight wrapping of the collar 202 on the lead-out wire 3.

[0042] In the present embodiment, the fixing ring 201 is mounted on the outer wall of the shell 1 and is tightened inward in the radial direction when subjected to an external force, thereby extruding the collar 202 to cause the deformation of the collar 202, and further tightly wrapping the collar 202 around the lead-out wire 3, so as to form a good seal between the lead-out wire 3 and the fixing ring 201, effectively preventing the water, dust and other impurities from the outside from entering the inside of the motor, improving the waterproof and dustproof performance of the motor, and ensuring the normal operation and service life of the internal components of the motor. The fixing ring 201 provides a stable mounting position for the collar 202, and the collar 202 is stably embedded in the lead-out hole 211 of the fixing ring 201, preventing the collar 202 from loosening and displacing under the action of external forces such as vibration and pulling of the lead-out wire 3 during the operation of the motor, ensuring that the collar 202 and the lead-out wire 3 always maintain a tight wrapping state and maintain good sealing effect, and also ensuring the stability of the connection between the lead-out wire 3 and the internal controller and other components of the motor, avoiding problems such as poor electrical connection caused by loosening of the lead-out wire 3. In addition, a structure basis for applying an external force is provided for the installation process, which facilitates the application of an external force to the fixing ring 201 by a tool or device to realize the deformation and sealing effect of the collar 202, making the installation process of the whole lead-out structure more convenient and efficient.

[0043] In the embodiment, the fixing ring 201 is installed on the outer wall of the shell 1, and the outgoing wire through hole 211 provides a channel for the outgoing wire 3. When the fixing ring 201 is radially tightened by external force, the sleeve ring 202 is extruded and deformed, thereby tightly wrapping the outgoing wire 3 and forming a first layer of sealing. At the same time, the connection between the fixing ring 201 and the shell 1 also provides a basic guarantee for the sealing, preventing moisture from seeping in from the joint between the fixing ring 201 and the shell 1, thereby forming a second layer of sealing, and together enhancing the waterproof performance of the motor. During the operation of the motor, the structure and synergistic effect of the fixing ring 201 and the sleeve ring 202 can adapt to changes such as vibration and temperature change, maintain the sealing effect, and the extrusion of the fixing ring 201 on the sleeve ring 202 ensures that the sleeve ring 202 always tightly wraps the outgoing wire 3. Even if the outgoing wire 3 is slightly displaced under certain vibration or temperature changes, the elastic deformation of the sleeve ring 202 can also be adjusted to ensure the reliability of the sealing and prevent moisture from seeping into the motor due to working condition changes. The fixing ring 201 is installed on the outer wall of the shell 1, providing stable support and positioning for the sleeve ring 202. The sleeve ring 202 is embedded in the outgoing wire through hole 211 of the fixing ring 201, and the structure of the fixing ring 201 limits the radial and axial movement of the sleeve ring 202, ensuring that the sleeve ring 202 does not displace or loosen during the operation of the motor, thereby ensuring the persistence and stability of the sealing effect between the outgoing wire 3 and the sleeve ring 202. Through the tight wrapping of the sleeve ring 202 on the outgoing wire 3 and the fixing of the fixing ring 201 on the sleeve ring 202, the connection between the outgoing wire 3 inside and outside the motor is firmly fixed, which not only prevents the outgoing wire 3 from being disconnected from the controller and other elements inside the motor due to external force pulling, but also reduces the shaking of the outgoing wire 3 under the action of vibration, improves the stability of the motor operation, and prolongs the service life of the outgoing wire 3 and the internal elements of the motor. During installation, the outgoing wire 3 is first inserted into the sleeve ring 202, then the sleeve ring 202 is installed in the outgoing wire through hole 211 of the fixing ring 201, and finally the fixing ring 201 is tightened by applying external force. This installation method simplifies the complex sealing and fixing operation into a few steps, making it easier for operators to assemble and improving production efficiency. At the same time, due to the reasonable structure of the fixing ring 201 and the sleeve ring 202, no additional complex tools or equipment are needed during installation, and the installation can be completed by applying appropriate external force, thereby reducing production costs.

[0044] For reference Figures 1 to 15 As shown in the figure, the fixing ring 201 protrudes from the outer wall of the shell 1, and the joint assembly 2 further includes an outer ring 203, which is sleeved on the outer peripheral wall of the fixing ring 201 to apply a circumferential wrapping force to the fixing ring 201.

[0045] Specifically, one end of the lead-out wire 3 is inserted from one end opening of the sleeve ring 202, passes through the inside of the sleeve ring 202, and the other end of the lead-out wire 3 is extended from the other end opening of the sleeve ring 202, the lead-out wire 3 is completed in the sleeve ring 202, the sleeve ring 202 which has been set with the lead-out wire 3 is aligned with the wire outlet through hole 211 on the fixed ring 201, and then the sleeve ring 202 is inserted into the wire outlet through hole 211, so that the outer wall of the sleeve ring 202 is tightly fitted with the inner wall of the wire outlet through hole 211, and the installation of the sleeve ring 202 in the wire outlet through hole 211 of the fixed ring 201 is completed. The outer ring 203 is sleeved on the outer peripheral wall of the fixed ring 201, the circumferential wrapping force is applied to the fixed ring 201, the fixed ring 201 is tightened inward in the radial direction, and due to the circumferential wrapping effect of the outer ring 203, the fixed ring 201 is more stable during the tightening process, the diameter of the wire outlet through hole 211 is uniformly reduced, and then the sleeve ring 202 is more uniformly extruded, so that the sleeve ring 202 is more uniformly deformed, and the inner wall of the sleeve ring 202 can be more tightly and uniformly fitted on the outer wall of the lead-out wire 3.

[0046] In the present embodiment, the outer ring 203 exerts a circumferential wrapping force on the fixing ring 201, so that the fixing ring 201 can be more uniformly tightened inward when subjected to external force, and in turn the sleeve ring 202 is more uniformly extruded, so that the contact between the sleeve ring 202 and the lead-out wire 3 can be more closely, the gap and void are reduced, thereby improving the reliability of the seal, effectively preventing impurities such as water, dust, etc. from entering the motor from the gap between the lead-out wire 3 and the fixing ring 201. During the operation of the motor, due to factors such as vibration, temperature change, etc., the sleeve ring 202 and the lead-out wire 3 may be deformed or displaced slightly, and the circumferential wrapping effect of the outer ring 203 on the fixing ring 201 can compensate for these deformations to some extent, maintain the extrusion state of the fixing ring 201 on the sleeve ring 202, ensure the persistence of the sealing effect, and avoid sealing failure due to deformation differences. The outer ring 203 is sleeved on the outer peripheral wall of the fixing ring 201, which limits the fixing ring 201 in the radial and axial directions, preventing the fixing ring 201 from moving radially or axially during the operation of the motor due to external force, which helps to maintain the stability of the connection between the lead-out wire 3 and the internal controller of the motor, and avoid the lead-out wire 3 loose or poor connection due to the displacement of the fixing ring 201. The addition of the outer ring 203 is equivalent to adding a layer of reinforcing structure outside the fixing ring 201, which improves the mechanical strength of the entire joint assembly 2, and when the motor is subjected to external impact, vibration and other harsh working conditions, the outer ring 203 can withstand external force together with the fixing ring 201, reducing the risk of damage or deformation of the fixing ring 201, thereby better protecting the lead-out wire 3 and the connection part inside the motor. This setting makes the installation process more simple. First, the lead-out wire 3 is inserted into the sleeve ring 202, then the sleeve ring 202 is inserted into the wire outlet hole 211 of the fixing ring 201, and then the outer ring 203 is sleeved and the fixing ring 201 is subjected to external force to realize sealing and fixing. The circumferential wrapping force of the outer ring 203 not only helps the fixing ring 201 to be stably tightened, but also ensures the sealing between the sleeve ring 202 and the lead-out wire 3 during installation, reducing the complex operation and possible errors in the installation steps. By adjusting the circumferential wrapping force of the outer ring 203 on the fixing ring 201, the extrusion degree of the fixing ring 201 on the sleeve ring 202 can be easily controlled.

[0047] In the embodiment, the fixing ring 201 is mounted on the outer wall of the shell 1, and the outgoing wire through hole 211 provides a channel for the outgoing wire 3. The sleeve ring 202 is embedded in the outgoing wire through hole 211 to preliminarily seal the outgoing wire 3. The outer ring 203 is sleeved on the outer peripheral wall of the fixing ring 201 to apply a circumferential wrapping force to the fixing ring 201. When the fixing ring 201 is tightened inward in the radial direction, the sleeve ring 202 can be more uniformly and stably extruded, so that the sleeve ring 202 more tightly wraps the outgoing wire 3 to form a more reliable and uniform sealing layer. At the same time, the connection between the fixing ring 201 and the shell 1 also provides a basic guarantee for sealing to prevent moisture from seeping from the joint between the fixing ring 201 and the shell 1, forming a multi-layer sealing structure to jointly enhance the waterproof and dustproof performance of the motor. The fixing ring 201 provides stable support and positioning for the sleeve ring 202, limiting the radial and axial movement of the sleeve ring 202. The outer ring 203 further enhances the stability of the fixing ring 201, so that the sleeve ring 202 will not be displaced or loosened due to external force during the operation of the motor, ensuring that the sleeve ring 202 and the outgoing wire 3 always maintain a tight wrapping state and maintain good sealing effect. Through the tight wrapping of the sleeve ring 202 to the outgoing wire 3 and the fixing of the sleeve ring 202 by the fixing ring 201 and the outer ring 203, the outgoing wire 3 is stably fixed at the connection between the inside and outside of the motor. This not only prevents the outgoing wire 3 from being disconnected from the controller and other elements inside the motor due to external pulling, but also reduces the shaking of the outgoing wire 3 under the action of vibration, improves the stability of the motor operation, and prolongs the service life of the outgoing wire 3 and the internal elements of the motor.

[0048] It is worth noting that the outer ring 203 can be made of a material with certain elasticity and strength, and the inner wall thereof is tightly fitted with the outer peripheral wall of the fixing ring 201. The circumferential wrapping force is applied to the fixing ring 201 through the elastic deformation of the outer ring 203 itself or by using other fixing methods (such as threaded connection, buckle connection, etc.).

[0049] For reference Figures 1 to 15 As shown in the figure, the joint assembly 2 further includes a locking member 204, which is a screw or a bolt. At least one locking member 204 is arranged in the circumferential direction of the outer ring 203. A connecting hole 231 is arranged on the outer peripheral wall of the outer ring 203. In the radial direction of the outer ring 203, one end of the locking member 204 penetrates into the connecting hole 231 and abuts against the outer peripheral wall of the fixing ring 201. The other end of the locking member 204 is installed in the connecting hole 231 to apply a radial extrusion force to the fixing ring 201.

[0050] Specifically, the outer ring 203 is sleeved on the outer peripheral wall of the fixed ring 201, at this time, the inner wall of the outer ring 203 is tightly attached to the outer peripheral wall of the fixed ring 201, a certain circumferential wrapping force is applied, the locking piece 204 is installed in the connecting hole 231 of the outer ring 203, one end of the locking piece 204 passes through the connecting hole 231 on the outer ring 203, and the other end of the locking piece 204 faces the outer peripheral wall of the fixed ring 201. The locking piece 204 is tightened. With the tightening of the locking piece 204, one end of the locking piece 204 gradually extrudes the outer peripheral wall of the fixed ring 201 inward, and the other end of the locking piece 204 gradually screws into the connecting hole 231. This tightening process can to some extent force the outer ring 203 to apply uniform wrapping force to the fixed ring 201 in the circumferential direction, and can also tighten the fixed ring 201 inward in the radial direction. The radial tightening of the fixed ring 201 further extrudes the sleeve ring 202, causes the sleeve ring 202 to deform, and makes the inner wall of the sleeve ring 202 tightly attached to the outer wall of the lead-out wire 3, thereby achieving good sealing effect. The tightening degree of the locking piece 204 can be adjusted according to actual needs to ensure that the sealing effect meets the waterproof and dustproof requirements of the motor.

[0051] In the embodiment, the tightening of the locking piece 204 can accurately apply radial extrusion force to the fixing ring 201, and by adjusting the tightening degree of the locking piece 204, the deformation degree of the fixing ring 201 can be controlled, so as to realize fine adjustment of the sealing force between the sleeve ring 202 and the lead-out wire 3, which helps to ensure that the sealing effect between the sleeve ring 202 and the lead-out wire 3 meets the waterproof and dustproof requirements of the motor, effectively preventing external water, dust and other impurities from entering the inside of the motor. During the tightening process of the locking piece 204, the outer ring 203 forces the fixing ring 201 to tighten inward uniformly, so that the sleeve ring 202 is uniformly extruded. This uniform extrusion can ensure that the contact between the sleeve ring 202 and the lead-out wire 3 is more closely and uniformly, avoiding the problem of uneven sealing caused by excessive or insufficient local pressure, and improving the reliability and stability of the sealing. One end of the locking piece 204 abuts against the outer peripheral wall of the fixing ring 201, and the other end is installed in the connecting hole 231. This structure limits the outer ring 203 in the circumferential and radial directions, preventing the outer ring 203 from loosening or displacing due to factors such as vibration and impact during motor operation, thereby ensuring the stable wrapping effect of the outer ring 203 on the fixing ring 201. The installation of the locking piece 204 is equivalent to adding a rigid connection between the fixing ring 201 and the outer ring 203, which improves the mechanical strength and rigidity of the entire joint assembly 2, which helps to enhance the resistance of the joint assembly 2 to external impact, vibration and other harsh working conditions, reduces the risk of damage or deformation of the fixing ring 201, the outer ring 203 and the sleeve ring 202, and ensures the stability and reliability of the motor lead-out wire 3 connection part. The use of the locking piece 204 makes the installation process simpler and more convenient. During installation, only the outer ring 203 needs to be sleeved on the fixing ring 201, and then the locking piece 204 is screwed into the connecting hole 231 and tightened to an appropriate degree, and the entire joint assembly 2 can be installed and sealed. This installation method does not require complex tools or equipment, reducing the installation difficulty and cost. The locking piece 204 provides flexible adjustment capability, which can be adjusted at any time according to actual needs. If the sealing effect is not ideal during installation, the locking piece 204 can be further tightened to enhance the sealing force; on the contrary, if the sealing force is too large and causes damage to the lead-out wire 3 or the sleeve ring 202, the locking piece 204 can be appropriately loosened for adjustment to ensure the best sealing state.

[0052] In the embodiment, the outer ring 203 applies a circumferential wrapping force to the fixing ring 201, so that the fixing ring 201 is constrained in the circumferential direction, and the locking member 204 applies a radial extrusion force to the fixing ring 201, so that the fixing ring 201 is tightened inwardly in the radial direction. The forces in the two directions cooperate with each other to promote the fixing ring 201 to more stably and uniformly extrude the sleeve ring 202, so that the contact between the sleeve ring 202 and the lead-out wire 3 is more closely, thereby significantly improving the sealing effect, effectively preventing moisture, dust and other impurities from entering the motor from the gap between the lead-out wire 3 and the fixing ring 201. The circumferential wrapping force of the outer ring 203 can preliminarily constrain the shape of the fixing ring 201, and the radial extrusion force of the locking member 204 can further adjust the deformation degree of the fixing ring 201. In actual application, the force of the outer ring 203 and the locking member 204 can be flexibly adjusted according to the waterproof and dustproof requirements of the motor and the characteristics of the lead-out wire 3, so that the sealing effect reaches the best state. The circumferential displacement of the fixing ring 201 is limited by the circumferential wrapping force of the outer ring 203, and the radial displacement of the fixing ring 201 is limited by the radial extrusion force of the locking member 204. The two forces jointly act on the fixing ring 201 to make the position of the fixing ring 201 in space more stable, thereby reducing the possibility of loosening or deformation of the fixing ring 201 due to vibration, impact and other factors during the operation of the motor, improving the fixing stability of the entire joint assembly 2, and ensuring the reliability of the connection between the lead-out wire 3 and the internal controller and other elements of the motor. The outer ring 203 and the locking member 204 respectively strengthen the fixing ring 201 from the circumferential direction and the radial direction, so that the structural strength of the fixing ring 201 is significantly improved. This multi-dimensional strengthening method enables the joint assembly 2 to better withstand external mechanical stress and environmental factors, reduces the risk of damage to the fixing ring 201, the sleeve ring 202 and the lead-out wire 3, and prolongs the service life of the motor. During installation, the outer ring 203 is first sleeved on the fixing ring 201 and a certain circumferential wrapping force is applied to preliminarily position and fix the fixing ring 201, thereby providing a stable basis for the subsequent installation of the locking member 204. Then, the locking member 204 is installed and tightened to further enhance the fixing effect and sealing performance of the fixing ring 201. This installation sequence is reasonable and efficient, facilitating the installation work of the operator, and also ensuring the installation quality. The cooperation of the outer ring 203 and the locking member 204 makes the installed joint assembly 2 have certain adjustability. If the sealing effect is not ideal or the position of the fixing ring 201 needs to be adjusted during installation, the circumferential wrapping force of the outer ring 203 or the radial extrusion force of the locking member 204 can be adjusted to achieve this purpose. This flexible adjustment capability helps to ensure that the installation quality of the joint assembly 2 meets the use requirements of the motor.

[0053] As a specific implementation, the fixing ring 201, the outer ring 203 and the sleeve ring 202 are all ring structures and are nested in sequence.

[0054] Referring to Figures 1 to 15 As shown, at least one adjusting groove 212 is arranged along the circumference of the fixing ring 201, and in the radial direction of the fixing ring 201, one end of the adjusting groove 212 extends to the outer edge of the fixing ring 201, and the other end of the adjusting groove 212 extends to the wire outlet through hole 211. The fixing ring 201 is pressed to narrow the adjusting groove 212 under the action of external force, and the depth and width of the adjusting groove 212 are flexibly set according to specific sealing requirements.

[0055] Specifically, the sleeve ring 202 which has been threaded with the lead-out wire 3 is aligned with the wire outlet through hole 211 on the fixing ring 201, and then the sleeve ring 202 is inserted into the wire outlet through hole 211 as a whole, so that the outer wall of the sleeve ring 202 tightly fits the inner wall of the wire outlet through hole 211, completing the installation of the sleeve ring 202 in the wire outlet through hole 211 of the fixing ring 201. The outer ring 203 is sleeved on the outer circumferential wall of the fixing ring 201, and the inner wall of the outer ring 203 tightly fits the outer circumferential wall of the fixing ring 201, at this time the outer ring 203 exerts a certain circumferential wrapping force on the fixing ring 201. The locking member 204 is installed in the connecting hole 231 of the outer ring 203, one end of the locking member 204 passes through the connecting hole 231 on the outer ring 203, and the other end faces the outer circumferential wall of the fixing ring 201. The locking member 204 is installed in the connecting hole 231 of the outer ring 203, one end of the locking member 204 passes through the connecting hole 231 on the outer ring 203, and the other end faces the outer circumferential wall of the fixing ring 201. The tightening of the locking member 204 forces the outer ring 203 to exert a more uniform wrapping force on the fixing ring 201 in the circumferential direction, and the radial extrusion force of the locking member 204 is transmitted to the fixing ring 201 through the outer ring 203, so that the fixing ring 201 is tightened inward in the radial direction. The adjusting groove 212 on the fixing ring 201 narrows when subjected to external force, so that the fixing ring 201 can deform more flexibly, thereby more uniformly pressing the sleeve ring 202, prompting the sleeve ring 202 to deform so that its inner wall tightly fits the outer wall of the lead-out wire 3, achieving good sealing effect.

[0056] In this embodiment, the adjusting groove 212 is arranged to make the fixed ring 201 more flexible when deformed under external force, and the external force is transmitted to the fixed ring 201 through the outer ring 203 and the locking piece 204. When the fixed ring 201 is tightened inward in the radial direction, the presence of the adjusting groove 212 allows the local area of the fixed ring 201 to bend and narrow more easily. The flexibility of this local deformation helps the fixed ring 201 to press the sleeve ring 202 more uniformly, making the contact between the sleeve ring 202 and the lead-out wire 3 more closely, thereby significantly improving the sealing effect. The arrangement of the adjusting groove 212 enables the fixed ring 201 to transmit pressure to the sleeve ring 202 more uniformly when under stress. Due to the presence of the adjusting groove 212, the pressure can be distributed more evenly around the sleeve ring 202 during the tightening process of the fixed ring 201, avoiding inconsistent sealing caused by uneven deformation of the fixed ring 201, and ensuring uniform and reliable sealing effect between the sleeve ring 202 and the lead-out wire 3. The presence of the adjusting groove 212 enables the fixed ring 201 to better adapt to lead-out wires 3 of different diameters or shapes. When the size of the lead-out wire 3 changes, the fixed ring 201 can flexibly adjust the degree of compression on the sleeve ring 202 through the narrowing degree of the adjusting groove 212, thereby ensuring that the sealing effect is not affected by the size difference of the lead-out wire 3. This improves the versatility and adaptability of the entire joint assembly 2, making it applicable to various motor settings and different specifications of lead-out wires 3. During the operation of the motor, it may be affected by complex working conditions such as vibration and temperature changes, causing slight changes in the relative position or deformation between the lead-out wire 3 and the fixed ring 201. The arrangement of the adjusting groove 212 enables the fixed ring 201 to respond quickly to these changes, and through local deformation adjustment, it always maintains good contact and sealing effect with the sleeve ring 202, ensuring reliable operation of the motor under various working conditions.

[0057] It is worth noting that the fixed ring 201 of this embodiment has two different structural forms, which are suitable for two different shell 1 structures. The specific shell 1 structure is a split end cover and a whole motor housing 13. The end cover is a stretch end cover structure, and the motor housing 13 is a plate rolling housing structure. Two corresponding fixed ring 201 structures are arranged for these two structures. The specific implementation is as follows:

[0058] For reference Figures 1 to 8 As the first fixed ring 201 structure, the fixed ring 201 includes a first fixed sheet 21 and a second fixed sheet 22. The first fixed sheet 21 and the second fixed sheet 22 are semi-annular, and the opening sides of the first fixed sheet 21 and the second fixed sheet 22 are arranged opposite to each other. The outflow hole 211 is formed between the inner walls of the first fixed sheet 21 and the second fixed sheet 22. The opening sides of the first fixed sheet 21 and the second fixed sheet 22 have a gap, and the gap forms an adjusting groove 212.

[0059] Specifically, the collar 202 that has been provided with the lead-out wire 3 is aligned with the lead-out hole 211 on the fixed ring 201, the lead-out hole 211 is formed by the inner walls of the first fixed sheet 21 and the second fixed sheet 22, the collar 202 is inserted into the lead-out hole 211, and the outer wall of the collar 202 is tightly fitted with the inner wall of the lead-out hole 211, thereby completing the installation of the collar 202 in the lead-out hole 211 of the fixed ring 201. The tightening of the locking member 204 forces the outer ring 203 to exert a more uniform wrapping force on the first fixed sheet 21 and the second fixed sheet 22 in the circumferential direction, and the radial extrusion force of the locking member 204 is transmitted to the first fixed sheet 21 and the second fixed sheet 22 through the outer ring 203, so that the first fixed sheet 21 and the second fixed sheet 22 are tightened inwardly in the radial direction, and the gap between the first fixed sheet 21 and the second fixed sheet 22, i.e., the adjusting groove 212, is narrowed when subjected to external force, so that the fixed ring 201 can be deformed more flexibly, and in turn, the collar 202 is extruded more uniformly.

[0060] In this embodiment, the split type arrangement allows the fixed ring 201 to deform more flexibly when subjected to external force, and the gap (adjusting groove 212) between the first fixed sheet 21 and the second fixed sheet 22 allows the fixed ring 201 to be more easily tightened inwardly in the radial direction, thereby extruding the collar 202 more uniformly, which makes the contact between the collar 202 and the lead-out wire 3 more closely, improves the sealing effect, and the presence of the adjusting groove 212 allows the fixed ring 201 to distribute the pressure more uniformly when subjected to force, so that the two semi-annular portions of the fixed ring 201 can be uniformly bent inwardly when the outer ring 203 and the locking member 204 apply external force, ensuring that the collar 202 is extruded uniformly, and avoiding sealing problems caused by uneven pressure. This structure can better adapt to lead-out wires 3 of different diameters or shapes, and by adjusting the gap between the first fixed sheet 21 and the second fixed sheet 22, it can to some extent adapt to lead-out wires 3 of different sizes, ensuring the sealing effect between the collar 202 and the lead-out wire 3. During the operation of the motor, it may be affected by complex working conditions such as vibration and temperature change, and this split type arrangement allows the fixed ring 201 to respond more flexibly to these changes, and by narrowing or expanding the adjusting groove 212, it maintains good contact with the collar 202, ensuring the durability of the sealing effect.

[0061] For reference Figures 1 to 8 As shown in FIG. 1, when the shell 1 is an end cover, the end cover includes a first cover body 11 and a second cover body 12 connected to each other, and first and second through holes are formed at the connection of the first and second cover bodies 11 and 12, respectively, and the inner walls of the first and second through holes form the mounting through hole 101; the first fixed sheet 21 is arranged at the first through hole and is integrally formed with the first cover body 11, and the second fixed sheet 22 is arranged at the second through hole and is integrally formed with the second cover body 12.

[0062] Specifically, the first cover body 11 is an upper end cover, and the second cover body 12 is a lower end cover. The sleeve ring 202, which has been provided with the outgoing line 3, is placed on the second fixing sheet 22 of the second end cover. The first cover body 11 is installed on the second cover body 12, so as to ensure that the first through hole and the second through hole are aligned to form a complete installation through hole 101. The first fixing sheet 21 and the second fixing sheet 22 form a complete fixing ring 201. The first cover body 11 and the second cover body 12 are fixed together by means of bolts, screws or other suitable connecting methods. At this time, the sleeve ring 202 is embedded in the outgoing line through hole 211.

[0063] In the embodiment, the split end cover is composed of the first cover body 11 and the second cover body 12. The first through hole and the second through hole are respectively formed at the connection positions of the first cover body 11 and the second cover body 12, so as to form a complete installation through hole 101. The first fixing sheet 21 and the second fixing sheet 22 are respectively arranged at the first through hole and the second through hole. This arrangement allows the two fixing sheets 23 to be adjusted and fixed respectively during the installation process, so as to ensure the sealing performance between the sleeve ring 202 and the outgoing line 3. The first fixing sheet 21 and the second fixing sheet 22 cooperate with the sleeve ring 202 to form a multi-layer sealing structure. After the sleeve ring 202 is inserted into the first through hole and the second through hole, the sleeve ring 202 is tightly attached to the inner walls of the first fixing sheet 21 and the second fixing sheet 22 respectively, so as to increase the reliability and redundancy of the sealing performance. This effectively prevents moisture and dust from entering the motor from the connection position of the end cover or the surrounding of the outgoing line 3. The first cover body 11 and the second cover body 12 are connected to form the overall structure of the end cover. The first fixing sheet 21 and the second fixing sheet 22 are respectively installed at the respective through holes. This layout allows the fixing ring 201 to be subjected to dispersed forces, so as to avoid stress concentration. External forces are uniformly transmitted to the fixing sheets 23, so as to improve the stability of the fixing sheets 23. This ensures that the fixing ring 201 is not easily deformed or displaced during the operation of the motor, so as to maintain good sealing and fixing performance of the sleeve ring 202 and the outgoing line 3. The first fixing sheet 21 and the second fixing sheet 22 are in the form of a semi-ring, and the opening sides thereof are opposite to each other. This forms the outgoing line through hole 211, which can adapt to outgoing lines 3 of different diameters. By adjusting the tightening degree of the locking member 204, the tightening degree of the fixing ring 201 can be changed. This realizes reliable fixing and sealing of outgoing lines 3 of different sizes, and improves the versatility of the joint assembly 2.

[0064] For reference Figures 9 to 15 As shown in FIG. 6, as a second fixing ring 201 structure, the fixing ring 201 includes a plurality of fixing sheets 23 in the form of a sector. The plurality of fixing sheets 23 are arranged around the same center. The inner walls of the plurality of fixing sheets 23 form the outgoing line through hole 211. Adjacent fixing sheets 23 have gaps therebetween. The gaps form adjustment grooves 212.

[0065] Specifically, align the sleeve 202 with the lead-out wire 3 with the out-line through hole 211 of the fixed ring 201, which is formed by the inner wall of the plurality of fixed pieces 23, install the locking piece 204 in the connecting hole 231 of the outer ring 203, one end of the locking piece 204 passes through the connecting hole 231 on the outer ring 203, and the other end is directed towards the outer peripheral wall of the fixed piece 23. The locking piece 204 forces the outer ring 203 to exert a circumferential wrapping force on the fixed piece 23, while transmitting a radial extrusion force to the fixed piece 23, causing the fixed piece 23 to tighten radially inward. The gap between adjacent fixed pieces 23 narrows when subjected to external force, allowing the fixed ring 201 to flexibly deform and uniformly extrude the sleeve 202. The sleeve 202 deforms after being extruded, with the inner wall tightly fitting the outer wall of the lead-out wire 3, achieving a seal.

[0066] In this embodiment, the inner walls of the plurality of fan-shaped fixed pieces 23 collectively form the out-line through hole 211. When the outer ring 203 and the locking piece 204 exert an external force, each fixed piece 23 can uniformly extrude the sleeve 202, making the contact between the sleeve 202 and the lead-out wire 3 more tight and uniform, thereby significantly improving the sealing effect. The gap between adjacent fixed pieces 23 forms an adjustment groove 212, allowing each fixed piece 23 to independently deform locally when subjected to external force. This flexibility of local deformation helps the fixed ring 201 better adapt to the shape of the sleeve 202 and the lead-out wire 3, further enhancing the sealing performance and effectively preventing moisture and dust from entering the motor from the gap between the lead-out wire 3 and the fixed ring 201. This structure can better adapt to lead-out wires 3 of different diameters or shapes. By adjusting the degree of tightening of the locking piece 204, the tightening degree of the fixed ring 201 can be changed, allowing the plurality of fixed pieces 23 to work together to reliably fix and seal lead-out wires 3 of different sizes, improving the versatility and adaptability of the joint assembly 2. Although the fixed ring 201 is composed of a plurality of fan-shaped fixed pieces 23, the strength of the entire structure is enhanced through the fixing action of the outer ring 203 and the locking piece 204. The outer ring 203 and the locking piece 204 work together to allow the fixed ring 201 to remain stable when subjected to external force, reducing the risk of excessive deformation or damage. This arrangement of multiple fan-shaped fixed pieces 23, combined with the fixing action of the outer ring 203 and the locking piece 204, improves the stability of the fixed ring 201, allowing it to maintain its shape and position more stably during motor operation, ensuring that the sealing effect between the sleeve 202 and the lead-out wire 3 does not fail due to vibration or impact.

[0067] For a better understanding of the present application, reference will be made to the following drawings in combination with the detailed description: Figures 9 to 15 As shown in the drawings, when the shell 1 is a motor housing 13, the motor housing 13 is provided with a mounting through hole 101, and the plurality of fixed pieces 23 are arranged at the mounting through hole 101.

[0068] Specifically, the collar 202 that has been provided with the lead-out wire 3 is aligned with the mounting through hole 101 on the motor housing 13, the mounting through hole 101 is provided with a plurality of fan-shaped fixing pieces 23, the inner walls of the fixing pieces 23 collectively form a lead-out through hole 211, the collar 202 is inserted into the lead-out through hole 211, the outer wall of the collar 202 is tightly fitted with the inner wall of the fixing piece 23, the installation of the collar 202 in the lead-out through hole 211 of the fixing ring 201 is completed, and the outer ring 203 is sleeved on the outer peripheral wall of the fixing ring 201. The inner wall of the outer ring 203 is tightly fitted with the outer wall of the fixing piece 23, at this time, the outer ring 203 exerts a certain circumferential wrapping force on the fixing ring 201, but has not caused significant radial deformation of the fixing ring 201, with the tightening of the locking piece 204, one end of the locking piece 204 gradually extrudes the outer peripheral wall of the fixing ring 201 inward, and the other end of the locking piece 204 gradually screws into the connecting hole 231. The tightening of the locking piece 204 forces the outer ring 203 to exert a more uniform wrapping force on the fixing ring 201 in the circumferential direction, and the radial extrusion force of the locking piece 204 is transmitted to the fixing ring 201 through the outer ring 203, so that the fixing ring 201 is tightened inward in the radial direction, the gap (adjusting groove 212) between adjacent fixing pieces 23 narrows when subjected to external force, so that the fixing ring 201 can deform more flexibly, and in turn extrude the collar 202 more uniformly, after the collar 202 is extruded by the fixing ring 201, it deforms, its inner wall is tightly fitted with the outer wall of the lead-out wire 3, thereby achieving good sealing effect.

[0069] In this embodiment, the inner walls of the plurality of fan-shaped fixing pieces 23 collectively form the outgoing line through hole 211, and when the outer ring 203 and the locking member 204 apply an external force, each fixing piece 23 can uniformly extrude the sleeve ring 202, making the contact between the sleeve ring 202 and the outgoing line 3 more closely and uniformly, thereby significantly improving the sealing effect. The gap between adjacent fixing pieces 23 forms an adjusting groove 212, so that each fixing piece 23 can independently deform locally when subjected to an external force. The flexibility of this local deformation helps the fixing ring 201 better adapt to the shape of the sleeve ring 202 and the outgoing line 3, further enhancing the sealing performance and effectively preventing moisture and dust from entering the motor from the gap between the outgoing line 3 and the fixing ring 201. When inserting the sleeve ring 202 into the outgoing line through hole 211 of the fixing ring 201, the plurality of fan-shaped fixing pieces 23 provide greater flexibility, facilitating the insertion of the sleeve ring 202. During the subsequent locking process, the presence of the adjusting groove 212 also makes it easier for the fixing ring 201 to be adjusted to the appropriate position, reducing the difficulty of installation. By adjusting the tightening degree of the locking member 204, the degree of deformation of the fixing ring 201 can be finely controlled, thereby optimizing the sealing effect. If the sealing effect is found to be unsatisfactory after installation, the sealing effect can be enhanced by further tightening the locking member 204. The combination of the plurality of fan-shaped fixing pieces 23 and the fixing effect of the outer ring 203 and the locking member 204 improves the stability of the fixing ring 201, which can more stably maintain its shape and position during motor operation, ensuring that the sealing effect between the sleeve ring 202 and the outgoing line 3 does not fail due to vibration or impact. Directly setting the fixing ring 201 at the mounting through hole 101 of the motor housing 13 makes the structure of the entire motor more compact, reducing the need for additional end covers or other components, and reducing the overall volume and weight of the motor. The fixing ring 201 is tightly coupled with the motor housing 13, not only achieving the sealing of the outgoing line 3, but also enhancing the overall sealing performance of the motor housing 13. The cooperation of the plurality of fixing pieces 23 and the motor housing 13 makes the sealing at the mounting through hole 101 more reliable, preventing external contaminants from entering the motor interior.

[0070] For reference Figures 1 to 16 As shown, the sleeve ring 202 is made of elastic material, and the sleeve ring 202 includes an annular body 221 and a radial flange 222. The outgoing line 3 is inserted through the annular body 221, and one end of the annular body 221 is embedded in the outgoing line through hole 211. The other end of the annular body 221 is provided with a radial flange 222, which extends outward from the outer wall of the annular body 221. The radial flange 222 abuts against the inner end face of the fixing ring 201.

[0071] Specifically, one end of the lead-out wire 3 is inserted from one end of the annular body 221 of the sleeve ring 202, passes through the inside of the annular body 221, and the other end of the lead-out wire 3 is extended from the other end of the annular body 221, completing the insertion of the lead-out wire 3 in the sleeve ring 202, ensuring that the annular body 221 of the sleeve ring 202 can smoothly pass through the wire outlet through hole 211 of the fixing ring 201, and the radial flange 222 can abut against the inner end face of the fixing ring 201. Align the annular body 221 of the sleeve ring 202 with the wire outlet through hole 211 of the fixing ring 201, insert the annular body 221 of the sleeve ring 202 into the wire outlet through hole 211 until the radial flange 222 abuts against the inner end face of the fixing ring 201, ensuring that the annular body 221 of the sleeve ring 202 is tightly fitted with the inner wall of the wire outlet through hole 211, and the outer ring 203 is sleeved on the outer peripheral wall of the fixing ring 201, and the inner wall of the outer ring 203 is tightly fitted with the outer peripheral wall of the fixing ring 201. At this time, the outer ring 203 exerts a certain circumferential wrapping force on the fixing ring 201, the locking member 204 is installed in the connecting hole 231 of the outer ring 203, one end of the locking member 204 passes through the connecting hole 231 on the outer ring 203, and the other end faces the outer peripheral wall of the fixing ring 201. With the tightening of the locking member 204, its one end gradually extrudes the outer peripheral wall of the fixing ring 201 inward, while the other end of the locking member 204 gradually screws into the connecting hole 231, and the tightening of the locking member 204 forces the outer ring 203 to exert a more uniform wrapping force on the fixing ring 201 in the circumferential direction, and the radial extrusion force of the locking member 204 is transmitted to the fixing ring 201 through the outer ring 203, causing the fixing ring 201 to tighten inward in the radial direction. The annular body 221 of the sleeve ring 202 is deformed after being extruded by the fixing ring 201, and its inner wall is tightly fitted with the outer wall of the lead-out wire 3, thereby achieving good sealing effect, at the same time, the radial flange 222 abuts against the inner end face of the fixing ring 201, further enhancing the sealing effect, preventing moisture and dust from entering the motor from the gap between the fixing ring 201 and the sleeve ring 202.

[0072] In this embodiment, the inner wall of the annular body 221 closely fits the lead-out wire 3, forming a first layer of sealing; the radial flange 222 abuts the inner end face of the fixed ring 201, forming a second layer of sealing, this double sealing structure significantly increases the sealing contact area, effectively preventing moisture and dust from entering the motor from the gap between the lead-out wire 3 and the fixed ring 201, the radial flange 222 abuts the inner end face of the fixed ring 201, forming a physical barrier, further enhancing the sealing effect, even if the sealing effect of the annular body 221 is slightly decreased due to some reasons, the radial flange 222 can play a supplementary sealing role, improving the reliability of the sealing. The radial flange 222 extends outward from the outer wall of the annular body 221 and abuts the inner end face of the fixed ring 201, this structure limits the movement of the sleeve ring 202 in the axial direction, ensures that the sleeve ring 202 maintains a stable position during the operation of the motor, avoids the axial displacement of the sleeve ring 202 due to vibration or tension, thereby ensuring the durability of the sealing effect, the setting of the radial flange 222 increases the overall structural strength of the sleeve ring 202, so that it can maintain its shape when subjected to radial and axial forces, reducing the possibility of deformation, thereby improving the durability and reliability of the sleeve ring 202. The radial flange 222 abuts the inner end face of the fixed ring 201, providing a clear positioning reference for installation, when installing the sleeve ring 202, only need to insert the annular body 221 into the wire outlet through hole 211 of the fixed ring 201 until the radial flange 222 contacts the inner end face of the fixed ring 201, which can ensure that the sleeve ring 202 is installed in place, simplifying the installation operation and improving the installation efficiency.

[0073] As a specific embodiment, as the first fixed ring 201 structure, the fixed ring 201 includes a first fixed sheet 21 and a second fixed sheet 22, and the shell 1 is an end cover, at this time, the outer wall of the outer ring 203 is provided with two connecting holes 231, and two locking members 204 are provided, that is, two locking members 204 are provided in the radial direction of the fixed ring 201, and one locking member 204 is provided on the first fixed sheet 21 and the second fixed sheet 22 respectively, that is, the first fixed sheet 21 and the second fixed sheet 22 are stressed in the radial direction respectively. As the second fixed ring 201 structure, four fixed rings 201 are specifically provided, and the shell 1 is a motor shell 13, at this time, the outer wall of the outer ring 203 is provided with four connecting holes 231, and four locking members 204 are provided, and each fixed sheet 23 corresponds to a locking member 204, and the four fixed sheets 23 are stressed in the radial direction respectively. In other embodiments, the installation position and number of the locking member 204 can be adjusted according to the required locking force.

[0074] A motor, the motor comprising a wire outlet structure, the wire outlet structure being the wire outlet structure described above.

[0075] In the embodiment, the outgoing line structure realizes reliable sealing of the outgoing line 3 through the cooperation of the fixing ring 201, the sleeve ring 202 and the outer ring 203 and the like, effectively prevents external water, dust and other impurities from entering the motor, improves the dustproof and waterproof performance of the motor, enhances the adaptability and reliability of the motor in harsh environments, the good sealing performance reduces the probability of occurrence of problems such as damage and short circuit of internal elements of the motor caused by invasion of external impurities, thereby prolonging the service life of the motor and reducing the maintenance cost. The arrangement of the sleeve ring 202 and the fixing ring 201 ensures that the outgoing line 3 is stably fixed at the connection between the inside and outside of the motor, reduces the risk of shaking and loosening of the outgoing line 3 during the operation of the motor, improves the stability of the motor operation, avoids motor failure caused by poor contact of the outgoing line 3, and the structure can adapt to vibration and impact during the operation of the motor, maintain the reliability of sealing and fixation, ensure that the motor can stably operate under various working conditions, and is especially suitable for application scenarios with high stability requirements.
