Description

Technical Field

[0001] The present invention relates to the technical field of insulating skeletons, and in particular to a skeleton component and a motor having the same. Background Art

[0002] Currently, in motors, the stator is the component that generates the rotating magnetic field. The stator windings are typically wound around the stator, separated by an insulating material. This insulating portion is shaped according to the winding method, known as the insulating skeleton. Generally, the mainstream stator structure for small brushless DC motors is a straight chain structure. This means the stator is typically wound in a straight state and then assembled into a circle to meet the motor's operational and installation requirements. The straight chain structure is foldable, simplifying winding complexity, improving production efficiency, reducing motor costs, and improving the motor's economical performance.

[0003] However, during stator winding, slots overlap between different phase windings, creating cross-slot bridges. The distance between these bridges during stator winding differs from the distance after stator rounding. After stator rounding, the slot spacing shortens, and the cross-slot bridges exceed the slot spacing. This can easily lead to loose bridge wires, causing them to detach from the stator frame and come into contact with the core, reducing stator quality. Furthermore, during the stator injection molding process, loose bridge wires can easily break, leading to quality issues such as poor insulation and withstand voltage, further reducing stator quality. Summary of the Invention

[0004] The main purpose of the present invention is to provide a skeleton assembly and a motor having the same, so as to solve the problem of poor quality of the motor stator in the prior art.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a skeleton assembly is provided, including: a bearing structure, having a winding portion and a wire passing recess, the winding portion is used for winding the wire harness, and the wire passing recess is used for allowing the wound wire harness to pass through; an abutment structure, movably arranged on the bearing structure, the abutment structure having an initial position and an abutment position; when the abutment structure is in the initial position, there is a preset distance between the abutment structure and the wire harness; when the abutment structure is in the abutment position, the abutment structure abuts against the wire harness passing through the wire passing recess to tighten the wire harness.

[0006] Furthermore, the skeleton assembly also includes a supporting structure, which is arranged on the bearing structure; wherein the supporting structure has a supporting recess, and at least part of the abutting structure extends into the supporting recess and is slidably arranged along the extension direction of the supporting recess.

[0007] Furthermore, the supporting structure has a first end and a second end arranged opposite to each other, and the second end is located on the side of the first end close to the winding part; the inner wall of the supporting recess has a plurality of first matching parts, and the plurality of first matching parts are arranged at intervals along the extension direction of the supporting recess; the abutment structure has a second matching part at one end facing the supporting recess; wherein, along the extension direction from the second end to the first end, the first matching part and the second matching part are slidingly matched; along the extension direction from the first end to the second end, the first matching part and the second matching part are snap-fitted to limit the second matching part.

[0008] Furthermore, the supporting recess includes a first recess and a second recess that are interconnected, the second recess is located on a side of the first recess away from the passing line recess, and the inner wall of the first recess has a plurality of first matching portions; the abutment structure includes a first abutment and a second abutment that are interconnected, the first abutment extends into the first recess, the second abutment extends into the second recess, and the first abutment has a second matching portion; wherein, the opening of the first recess is larger than the opening of the second recess, so that the inner wall of the second recess limits the first abutment.

[0009] Furthermore, the skeleton assembly also includes: a limiting structure, which is arranged on the inner wall of the supporting recess, and the limiting structure is located on the side of the multiple first matching parts close to the first end; wherein, along the direction from the second end to the first end, the limiting structure abuts against at least part of the second matching parts to limit and stop the abutting structure.

[0010] Furthermore, the second matching portion further includes a stop section and a clamping section that are connected to each other, the stop section abuts against the limiting structure, and the clamping section is clamped and matched with the first matching portion.

[0011] Furthermore, the abutting structure also has an avoidance groove, and the second matching portion is located in the avoidance groove; wherein, the avoidance groove is used for the limiting structure to extend into.

[0012] Furthermore, the support structure also has an accommodating recess, which is used to accommodate at least part of the wiring harness; wherein the inner wall of the accommodating recess is arranged in an arc shape.

[0013] Furthermore, the abutting structure has an abutting recess, and when the abutting structure is in the abutting position, the abutting recess is used to accommodate at least part of the wiring harness; wherein the inner wall of the abutting recess is arranged in an arc shape.

At this time, the abutting structure is in the initial position and does not contact the wire harness, so that the smoothness of the wire harness winding is ensured. After the wire harness is wound and the plurality of framework assemblies are spliced into a circle, the distance between the adjacent two framework assemblies is shortened, so that the wire harness passing through the wire passing recess is loosened. At this time, the abutting structure is in the abutting position, the abutting structure abuts against the wire harness passing through the wire passing recess, and pushes the wire harness to tighten the wire harness, so that the loosening of the wire harness is avoided, the quality of the motor stator is improved, and the problem of poor quality of the motor stator in the prior art is solved.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0037] In order to solve the problem of poor quality of motor stators in the prior art, the present application provides a skeleton assembly and a motor having the same.

[0038] like Figures 1 to 10 As shown, the skeleton assembly includes a supporting structure 10 and an abutment structure 20. The supporting structure 10 has a winding portion 11 and a wire passing recess 15. The winding portion 11 is used to wind the wire harness 3, and the wire passing recess 15 is used to pass the wound wire harness 3 through. The abutment structure 20 is movably arranged on the supporting structure 10 and has an initial position and an abutment position. When the abutment structure 20 is in the initial position, there is a preset distance between the abutment structure 20 and the wire harness 3. When the abutment structure 20 is in the abutment position, the abutment structure 20 abuts against the wire harness 3 passing through the wire passing recess 15 to tighten the wire harness 3.

[0039] Applying the technical solution of this embodiment, the support structure 10 of the skeleton assembly has a winding portion 11 and a wire-passing recess 15. The winding portion 11 is used to wind the wire harness 3, and the wire-passing recess 15 is used to pass the wound wire harness 3 through. An abutment structure 20 is movably mounted on the support structure 10 and has an initial position and an abutment position. When the abutment structure 20 is in the initial position, a predetermined distance exists between the abutment structure 20 and the wire harness 3. When the abutment structure 20 is in the abutment position, the abutment structure 20 abuts the wire harness 3 passing through the wire-passing recess 15, thereby tightening the wire harness 3. In this way, when the stator is arranged in a linear chain structure, multiple skeleton assemblies are arranged in a linear chain. The wire harness 3 is wound around the support structure 10 through the support portion 12, passes through the wire-passing recess 15, and then is wound around the support structure 10 of the next skeleton assembly, ensuring the continuity of the winding of the wire harness 3. At this time, the abutment structure 20 is in the initial position and does not contact the wire harness 3, ensuring smooth winding of the wire harness 3. After the wiring harness 3 is wound and the multiple skeleton components are spliced ​​into a circle, the distance between adjacent skeleton components becomes shorter, causing the wiring harness 3 passing through the wire-passing recess 15 to become loose. At this time, the abutment structure 20 is in the abutment position, abutting the wiring harness 3 passing through the wire-passing recess 15 and pushing the wiring harness 3 to make it taut, thus preventing the wiring harness 3 from loosening, thereby improving the quality of the motor stator and solving the problem of poor quality of the motor stator in the prior art.

[0040] In this embodiment, the supporting structure 10 is made of plastic.

[0041] In this embodiment, the wire harness 3 is an enameled wire.

[0042] like Figure 1 、 Figure 5 and Figure 10As shown, the skeleton assembly also includes a support structure 30, which is arranged on the supporting structure 10. The support structure 30 has a support recess 31, and at least part of the abutment structure 20 extends into the support recess 31 and is slidably arranged along the extension direction of the support recess 31. In this way, the support structure 30 accommodates the abutment structure 20 through the support recess 31, so that the abutment structure 20 can switch from the initial position to the abutment position by sliding along the support recess 31, and can also be movably arranged on the supporting structure 10. At the same time, the arrangement of the support structure 30 can, on the one hand, provide a support point for the movement of the abutment structure 20, thereby ensuring the movement stability and reliability of the abutment structure 20; on the other hand, it can accommodate the abutment structure 20, rationally plan the placement space of the abutment structure 20, ensure the structural compactness of the skeleton assembly, and also ensure the miniaturization design of the skeleton assembly.

[0043] In this embodiment, the bearing structure 10 includes a bearing portion 12, a first blocking portion 13, and a second blocking portion 14. The bearing portion 12 is connected to the winding portion 11. The first blocking portion 13 is arranged at one end of the bearing portion 12 close to the winding portion 11. The second blocking portion 14 is arranged at one end of the bearing portion 12 away from the winding portion 11. A wire-passing recess 15 is formed around at least part of the bearing portion 12, the first blocking portion 13, and the second blocking portion 14. In this way, the bearing structure 10 supports and supports each structure through the bearing portion 12, thereby ensuring the installation stability of each structure. At the same time, the wire-passing recess 15 is formed around at least part of the bearing portion 12, the first blocking portion 13, and the second blocking portion 14, making the formation of the wire-passing recess 15 simpler and easier to implement, thereby improving the formation efficiency of the wire-passing recess 15. At the same time, the first blocking portion 13 can separate the wire harness 3 in the wire-passing recess 15 from the wire harness 3 in the winding portion 11, thereby avoiding entanglement between the wire harnesses 3 and ensuring the operation safety of the wire harness 3.

[0044] In this embodiment, two support structures 30 are provided. The two support structures 30 are relatively arranged at both ends of the bearing portion 12 along the extension direction of the cross-line recess 15 , and the two support structures 30 are respectively located on both sides of the first blocking portion 13 and the second blocking portion 14 .

[0045] Specifically, two abutment structures 20 are provided, and the two abutment structures 20 are provided in a one-to-one correspondence with the two support structures 30. In this way, the two abutment structures 20 can abut the wire harness 3 on opposite sides of the wire-passing recess 15, further pushing the wire harness 3 away from the support structure 30, further tightening the wire harness 3, and further improving the quality of the motor stator.

[0046] In this embodiment, the skeleton assembly further includes a blocking structure 50, which is disposed at one end of the winding portion 11 away from the load-bearing portion 12. The blocking structure 50 contacts at least a portion of the wire harness 3 on the winding portion 11 to limit and stop the wire harness 3. In this way, when the wire harness 3 is wound around the winding portion 11, the blocking structure 50 disposed at the end of the winding portion 11 away from the load-bearing portion 12 can limit and stop the wire harness 3, thereby preventing the wire harness 3 from falling off the winding portion 11, ensuring the winding reliability and neatness of the wire harness 3, and preventing the wire harness 3 from being tangled or rubbed due to vibration during the operation of the motor, thereby reducing the risk of damage to the wire harness 3 and improving the reliability and safety of the motor.

[0047] like Figures 1 to 3As shown, the support structure 30 has a first end and a second end disposed opposite each other, with the second end located on the side of the first end closer to the winding portion 11. The inner wall of the support recess 31 has a plurality of first mating portions 32 spaced apart along the extension direction of the support recess 31. The abutment structure 20 has a second mating portion 23 at one end facing the support recess 31. The first mating portion 32 and the second mating portion 23 slide together along the direction extending from the second end to the first end. Along the direction extending from the first end to the second end, the first mating portion 32 and the second mating portion 23 engage with each other to limit the position of the second mating portion 23. Thus, the sliding engagement of the first mating portion 32 and the second mating portion 23 along the direction extending from the second end to the first end of the support structure 30 ensures that the abutment structure 20 can slide out of the support recess 31, allowing the abutment structure 20 to switch from its initial position to the abutting position, thereby achieving abutment with the wiring harness 3 passing through the wire passing recess 15 and ensuring the reliability of the tension of the wiring harness 3. At the same time, when the abutment structure 20 abuts against the wiring harness 3 to tighten the wiring harness 3, the first mating portion 32 and the second mating portion 23 engage in a snap-fitting manner from the first end to the second end, allowing the abutment structure 20 to continuously and stably abut against the wiring harness 3, thereby preventing the abutment structure 20 from sliding and causing the wiring harness 3 to loosen. This further ensures the tightening reliability of the wiring harness 3, improves the quality of the motor stator, and enhances the abutment reliability and stability of the abutment structure 20. At the same time, the arrangement of multiple first mating portions 32 allows the abutment position of the abutment structure 20 to be adjusted according to the requirements of stators of different specifications and sizes to accommodate wiring harnesses 3 with different degrees of looseness, thereby expanding the range of abutment positions, improving the versatility of the abutment structure 20, and thereby improving the versatility of the skeleton assembly. At the same time, the setting method of the first matching part 32 and the second matching part 23 enables the abutment structure 20 to have the function of one-way movement and reverse locking. The staff only needs to push the abutment structure 20 to slide toward the wiring harness 3 to achieve the pushing of the abutment structure 20. No additional fixing parts are required, which simplifies the staff's operating steps, reduces the staff's work difficulty, improves the staff's work efficiency, reduces the structural complexity of the skeleton assembly, reduces material and production costs, and improves the economy of the skeleton assembly.

[0048] like Figure 4As shown, the support recess 31 includes a first recess 311 and a second recess 312 that are interconnected. The second recess 312 is located on the side of the first recess 311 away from the line recess 15. The inner wall of the first recess 311 has a plurality of first mating portions 32. The abutment structure 20 includes a first abutment portion 21 and a second abutment portion 22 that are interconnected. The first abutment portion 21 extends into the first recess 311, and the second abutment portion 22 extends into the second recess 312. The first abutment portion 21 has a second mating portion 23. The opening of the first recess 311 is larger than that of the second recess 312, so that the inner wall of the second recess 312 limits the first abutment portion 21. In this way, when the first abutting portion 21 extends into the first recess 311, the inner wall of the second recess 312 can limit and stop the end of the first abutting portion 21 close to the second abutting portion 22, preventing the abutting structure 20 from falling off from the opening of the support recess 31, thereby ensuring the installation stability and sliding reliability of the abutting structure 20. At the same time, the second recess 312 can accommodate the second abutting portion 22, allowing the staff to push the abutting structure 20 by pushing the second abutting portion 22, thereby achieving smooth and reliable switching of the abutting structure 20 from the initial position to the abutting position. At the same time, the above-mentioned arrangement achieves a limit stop for the abutting structure 20 through the inner wall of the second recess 312, avoiding the need for an additional limiting structure 40, simplifying the structural composition of the skeleton assembly, reducing the structural complexity of the skeleton assembly, effectively utilizing the support structure 30, and improving the structural compactness and miniaturization design of the skeleton assembly.

[0049] In this embodiment, the second matching portion 23 is provided on the first abutting portion 21 .

[0050] Specifically, the shape of the abutting structure 20 is similar to a “convex” shape.

[0051] like Figure 3 、 Figure 4 and Figure 6 As shown, the skeleton assembly also includes a limiting structure 40. The limiting structure 40 is arranged on the inner wall of the support recess 31, and the limiting structure 40 is located on the side of the multiple first matching parts 32 close to the first end. Among them, along the direction from the second end to the first end, the limiting structure 40 abuts against at least part of the second matching part 23 to limit and stop the abutment structure 20. In this way, when the staff pushes the abutment structure 20 to slide from the initial position to the abutment position, the limiting structure 40 can abut against the second matching part 23, determine the maximum range of motion of the abutment structure 20, avoid the abutment structure 20 from being disengaged from the end of the support recess 31 due to excessive adjustment, and cause damage to the abutment structure 20, thereby ensuring the operational reliability and safety of the abutment structure 20.

[0052] like Figure 7As shown, the second mating portion 23 also includes a stopper section 231 and a snap-fit ​​section 232 that are interconnected. The stopper section 231 abuts the limiting structure 40, while the snap-fit ​​section 232 snap-fits with the first mating portion 32. Thus, the second mating portion 23 achieves abutment contact with the limiting structure 40 via the stopper section 231, ensuring that the limiting structure 40 can prevent the abutting structure 20 from continuing to move, thereby ensuring the operational safety and reliability of the abutting structure 20. Simultaneously, the second mating portion 23 achieves a snap-fit ​​with the first mating portion 32 via the snap-fit ​​section 232, ensuring that the first mating portion 32 can prevent the abutting structure 20 from sliding in a direction away from the wiring harness 3, thereby ensuring the abutment stability and reliability of the abutting structure 20 when in the abutting position. At the same time, the setting method of the stop section 231 and the locking section 232 makes the structure of the second matching part 23 relatively simple, reduces the processing difficulty of the staff, improves the processing efficiency of the staff, and also makes the adjustment steps of the abutment structure 20 more intuitive and simple. After the staff pushes the abutment structure 20 to the abutment position, it slightly withdraws it so that the locking section 232 is engaged with the most suitable first matching part 32, thereby completing the adjustment of the tension of the wiring harness 3 without the need for complicated manual or tool assistance, thereby improving the work efficiency and operation convenience of the staff.

[0053] like Figure 7 As shown, the abutment structure 20 further comprises an escape groove 25, within which the second mating portion 23 is located. The escape groove 25 is used to allow the limiting structure 40 to extend therein. Thus, the limiting structure 40 extends into the escape groove 25, further tightening the fit between the limiting structure 40 and the abutment structure 20. This not only reduces the space occupied by the limiting structure 40 and the abutment structure 20, but also improves the overall structural compactness and space utilization of the skeleton assembly. It also ensures that the limiting structure 40 can accurately extend into the abutment structure 20 and abut against the stop section 231, effectively limiting the range of motion of the abutment structure 20 and improving the operational safety of the abutment structure 20. Furthermore, the arrangement of the limiting structure 40 extending into the escape groove 25 ensures that the abutment structure 20 is stopped while also ensuring smooth sliding of the abutment structure 20, avoiding wear on the limiting structure 40 and ensuring the structural strength of the limiting structure 40.

[0054] In this embodiment, at least a portion of the stopping section 231 is located in the avoidance groove 25 , which facilitates abutment with the limiting structure 40 , thereby improving the reliability and convenience of the abutment between the limiting structure 40 and the second matching portion 23 .

[0055] like Figure 2 、 Figure 3 and Figure 6As shown, the support structure 30 also has a accommodating recess 33, which is used to accommodate at least part of the wiring harness 3. The inner wall of the accommodating recess 33 is arranged in an arc shape. In this way, the arrangement of the accommodating recess 33 can provide a safe accommodating space for the wiring harness 3, can perform a certain positioning function on the wiring harness 3, and ensure the neatness and accuracy of the routing of the wiring harness 3. At the same time, the arc-shaped inner wall of the accommodating recess 33 can, on the one hand, effectively fit the shape of the wiring harness 3, avoid the vibration of the wiring harness 3 under the action of external force, and cause the phenomenon of offset or wear, thereby ensuring the position accuracy of the wiring harness 3 and extending the service life of the wiring harness 3; on the other hand, it can effectively disperse the stress on the wiring harness 3, avoid local stress concentration and damage to the wiring harness 3, further extend the service life of the wiring harness 3, and improve the operating stability of the wiring harness 3.

[0056] Optionally, the inner wall of the accommodating recess 33 may also be in a shape of “]”, “>”, etc., so as to improve the processing flexibility of the accommodating recess 33.

[0057] like Figure 2 and Figure 7 As shown, the abutment structure 20 has an abutment recess 24. When the abutment structure 20 is in the abutment position, the abutment recess 24 is used to accommodate at least part of the wiring harness 3. The inner wall of the abutment recess 24 is arranged in an arc shape. In this way, the arrangement of the abutment recess 24 can provide a safe accommodation space for the wiring harness 3, can position and abut the wiring harness 3, and ensure the abutment reliability of the wiring harness 3. At the same time, the arc-shaped inner wall of the abutment recess 24 can, on the one hand, effectively fit the shape of the wiring harness 3, avoid the vibration of the wiring harness 3 under the action of external force, and cause excessive offset or wear, thereby ensuring the position accuracy of the wiring harness 3 and extending the service life of the wiring harness 3; on the other hand, it can effectively disperse the stress on the wiring harness 3, avoid local stress concentration and damage to the wiring harness 3, further extend the service life of the wiring harness 3, and improve the operating stability of the wiring harness 3.

[0058] Optionally, the inner wall of the abutting recess 24 may also be in a shape of “]”, “>”, etc., so as to improve the processing flexibility of the abutting recess 24 .

[0059] In this embodiment, the contact portion between the abutting structure 20 and the wire harness 3 is also chamfered, and the edges of the abutting structure 20 are also chamfered.

[0060] The present application also provides a motor, which includes the above-mentioned skeleton assembly.

[0061] Specifically, the motor further includes a plurality of stator assemblies, which are arranged in sequence and arranged in a circle.

[0062] like Figure 8 and Figure 9The stator assembly shown includes a stator core 1, a skeleton assembly and a skeleton structure 2. The stator core 1 has a connecting groove 101. The skeleton assembly and the skeleton structure 2 are both connected to the stator core 1 through the connecting groove 101. The skeleton assembly is the above-mentioned skeleton assembly.

[0063] Optionally, the skeleton assembly, the skeleton structure 2 and the stator core 1 are integrally injection-molded.

[0064] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0065] The support structure of the frame assembly includes a winding portion and a wire-passing recess. The winding portion is used to wind the wire harness, while the wire-passing recess is used to pass the wound wire harness through. An abutment structure is movably mounted on the support structure and has an initial position and an abutment position. When the abutment structure is in the initial position, a predetermined distance exists between the abutment structure and the wire harness. When the abutment structure is in the abutment position, the abutment structure abuts the wire harness passing through the wire-passing recess, tightening the wire harness. In this way, when the stator is arranged in a linear chain configuration, multiple frame assemblies are arranged in a linear chain. The wire harness is wound around the support structure through the supporting portion, passes through the wire-passing recess, and then is wound around the support structure of the next frame assembly, ensuring continuous winding of the wire harness. At this time, the abutment structure is in the initial position and does not contact the wire harness, ensuring smooth winding of the wire harness. After the wire harness is wound and the multiple frame assemblies are joined into a circle, the distance between adjacent frame assemblies decreases, causing the wire harness passing through the wire-passing recess to loosen. At this time, the abutment structure is in the abutment position, and the abutment structure abuts against the wire harness passing through the wire recess, and pushes the wire harness to make it tight, avoiding the phenomenon of loose wire harness, thereby improving the quality of the motor stator, and solving the problem of poor quality of the motor stator in the prior art.
