Description

Technical Field

[0001] This invention relates to the field of insulating frame technology, and more specifically, to a frame assembly and a motor having the same. Background Technology

[0002] Currently, in electric motors, the stator is the component that generates the rotating magnetic field. The windings on the stator are usually wound around the stator, and the two are separated by insulating material. The insulating part is shaped according to the winding method, and we call it the insulating skeleton. Generally, the mainstream stator structure of small brushless DC motors is a straight-chain structure, that is, the stator is usually wound in a straight state first, and then spliced ​​into a circle after winding to meet the requirements of motor operation and installation. The straight-chain structure has foldability, reduces the difficulty of winding, improves production efficiency, reduces motor cost, and improves the economics of the motor.

[0003] However, during stator winding, slots are crossed between different phase windings, creating bridging wires. The distance between these bridging wires during stator winding differs from the distance after the stator is rounded. After the stator is rounded, the slot spacing becomes shorter, and the bridging wires exceed the slot spacing length, easily leading to loose bridging wires. This can cause the bridging wires to detach from the frame, posing a risk of contact with the core and reducing stator quality. Furthermore, during stator injection molding, loose bridging wires can easily break, leading to insulation and withstand voltage problems, further reducing stator quality. Summary of the Invention

[0004] The main objective of this invention is to provide a frame assembly and a motor having the same, in order to solve the problem of poor stator quality in existing motors.

[0005] To achieve the above objectives, according to one aspect of the present invention, a skeleton assembly is provided, comprising: a support structure having a winding portion and a passing recess, the winding portion being for winding a wire harness, and the passing recess being for the wound wire harness to pass through; and an abutment structure movably disposed on the support 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 passing recess to tighten the wire harness.

[0006] Furthermore, the skeleton assembly also includes a support structure disposed on the load-bearing structure; wherein the support structure has a support recess, and at least part of the abutment structure extends into the support recess and is slidably disposed along the extending direction of the support recess.

[0007] Furthermore, the support structure has a first end and a second end that are disposed opposite to each other, with the second end located on the side of the first end near the winding portion; the inner wall of the support recess has a plurality of first mating portions, which are spaced apart along the extending direction of the support recess; the end of the abutment structure facing the support recess has a second mating portion; wherein, along the extending direction from the second end to the first end, the first mating portion and the second mating portion slide together; along the extending direction from the first end to the second end, the first mating portion and the second mating portion engage to limit and stop the second mating portion.

[0008] Furthermore, the supporting recess includes a first recess and a second recess that are interconnected. The second recess is located on the side of the first recess away from the through-line recess. The inner wall of the first recess has a plurality of first mating parts. The abutting structure includes a first abutting part and a second abutting part that are interconnected. The first abutting part extends into the first recess, and the second abutting part extends into the second recess. The first abutting part has a second mating part. 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 and stops the first abutting part.

[0009] Furthermore, the skeleton assembly also includes: a limiting structure disposed on the inner wall of the support recess, the limiting structure being located on the side of the plurality of first mating parts near the first end; wherein, along the direction from the second end to the first end, the limiting structure abuts against at least a portion of the second mating parts to limit and stop the abutment structure.

[0010] Furthermore, the second mating part also includes a stop section and a locking section that are connected to each other. The stop section abuts against the limiting structure, and the locking section engages with the first mating part.

[0011] Furthermore, the abutment structure also has a clearance groove, and the second mating part is located in the clearance groove; wherein, the clearance groove is used for the insertion of the limiting structure.

[0012] Furthermore, the support structure also has a receiving recess for accommodating at least a portion of the wire harness; wherein the inner wall of the receiving recess is arc-shaped.

[0013] Furthermore, the abutting structure has an abutting recess, which is used to accommodate at least a portion of the wire harness when the abutting structure is in the abutting position; wherein the inner wall of the abutting recess is arc-shaped.

[0014] According to another aspect of the invention, an electric motor is also provided, the motor including the aforementioned frame assembly.

[0015] According to the technical solution of this invention, the supporting structure of the skeleton assembly has 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 the wound wire harness to pass through. An abutment structure is movably disposed on the supporting structure, and the abutment structure has 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. Thus, when the stator has a linear chain structure, multiple skeleton assemblies are arranged in a linear chain, and the wire harness winds around the supporting structure through the supporting portion, passes through the wire-passing recess, and winds onto the supporting structure of the next skeleton assembly, ensuring the continuity of the wire harness winding. At this time, the abutment structure is in the initial position and does not contact the wire harness, ensuring the smooth winding of the wire harness. Afterwards, when the wire harness winding is completed and multiple skeleton assemblies are spliced ​​into a circle, the distance between two adjacent skeleton assemblies becomes shorter, causing the wire harness passing through the wire-passing recess to loosen. At this time, the abutting structure is in the abutting position, and the abutting structure abuts against the wire harness passing through the wire recess, and pushes the wire harness to make the wire harness taut, avoiding the phenomenon of wire harness loosening, thereby improving the quality of the motor stator, and thus solving the problem of poor quality of motor stator in the prior art.

[0037] To address the problem of poor stator quality in existing motor technologies, this application provides a frame assembly and a motor having the same.

[0038] like Figures 1 to 10 As shown, the skeleton assembly includes a support structure 10 and an abutment structure 20. The support structure 10 has a winding portion 11 and a wire-passing recess 15. The winding portion 11 is used for winding the wire harness 3, and the wire-passing recess 15 is used for the wound wire harness 3 to pass through. The abutment structure 20 is movably disposed on the support structure 10, and the abutment structure 20 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 supporting structure 10 of the skeleton assembly has a winding portion 11 and a wire-passing recess 15. The winding portion 11 is used for winding the wire harness 3, and the wire-passing recess 15 is used for the wound wire harness 3 to pass through. The abutting structure 20 is movably disposed on the supporting structure 10, and the abutting structure 20 has an initial position and an abutting position. When the abutting structure 20 is in the initial position, there is a preset distance between the abutting structure 20 and the wire harness 3; when the abutting structure 20 is in the abutting position, the abutting structure 20 abuts against the wire harness 3 passing through the wire-passing recess 15 to tighten the wire harness 3. In this way, when the stator has a linear chain structure, multiple skeleton assemblies are arranged in a linear chain, and the wire harness 3 is wound on the supporting structure 10 through the supporting portion 12, and after passing through the wire-passing recess 15, it is wound on the supporting structure 10 of the next skeleton assembly, ensuring the continuity of the winding of the wire harness 3. At this time, the abutting structure 20 is in the initial position and does not contact the wire harness 3, ensuring the smooth winding of the wire harness 3. After the wire harness 3 is wound and multiple skeleton components are assembled into a circle, the distance between two adjacent skeleton components becomes shorter, causing the wire harness 3 passing through the wire-passing recess 15 to loosen. At this time, the abutting structure 20 is in the abutting position, abutting against the wire harness 3 passing through the wire-passing recess 15, and pushing the wire harness 3 to tighten it, thus preventing the wire harness 3 from loosening, thereby improving the quality of the motor stator and solving the problem of poor motor stator quality in the prior art.

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

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

[0042] like Figure 1 , Figure 5 and Figure 10As shown, the skeleton assembly also includes a support structure 30, which is disposed on the load-bearing structure 10. The support structure 30 has a support recess 31, into which at least a portion of the abutment structure 20 extends and is slidably disposed along the extending direction of the support recess 31. In this way, the support structure 30 accommodates the abutment structure 20 through the support recess 31, allowing the abutment structure 20 to switch from its initial position to its abutment position by sliding along the support recess 31, and also enabling its movable placement on the load-bearing structure 10. Simultaneously, the arrangement of the support structure 30 provides a support point for the movement of the abutment structure 20, ensuring the stability and reliability of its movement; furthermore, it accommodates the abutment structure 20, rationally planning its placement space, ensuring the structural compactness of the skeleton assembly, and also guaranteeing its miniaturized design.

[0043] In this embodiment, the supporting structure 10 includes a supporting portion 12, a first blocking portion 13, and a second blocking portion 14. The supporting portion 12 is connected to the winding portion 11. The first blocking portion 13 is disposed at one end of the supporting portion 12 near the winding portion 11. The second blocking portion 14 is disposed at one end of the supporting portion 12 away from the winding portion 11. At least a portion of the supporting portion 12, the first blocking portion 13, and the second blocking portion 14 surround each other to form a wire-passing recess 15. Thus, the supporting structure 10 provides support and load-bearing for each structure through the supporting portion 12, ensuring the installation stability of each structure. Simultaneously, the formation of the wire-passing recess 15 by at least a portion of the supporting portion 12, the first blocking portion 13, and the second blocking portion 14 simplifies the formation of the wire-passing recess 15, making it easier to implement and improving the formation efficiency of the wire-passing recess 15. Furthermore, the first blocking portion 13 can separate the wire bundle 3 within the wire-passing recess 15 from the wire bundle 3 of the winding portion 11, preventing entanglement between the wire bundles 3 and ensuring the operational safety of the wire bundle 3.

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

[0045] Specifically, two abutment structures 20 are also provided, with each abutment structure 20 corresponding to one of the two support structures 30. In this way, the two abutment structures 20 can abut against the wire harness 3 on both sides of the wire passage 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 frame assembly further includes a partition structure 50, which is disposed at the end of the winding portion 11 away from the support portion 12. The partition 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. Thus, when the wire harness 3 is wound around the winding portion 11, the partition structure 50 at the end of the winding portion 11 away from the support portion 12 can limit and stop the wire harness 3, preventing it from falling off the winding portion 11, ensuring the reliability and neatness of the winding, preventing the wire harness 3 from becoming tangled or rubbing due to vibration during motor operation, 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 to each other, with the second end located on the side of the first end near the winding portion 11. The inner wall of the support recess 31 has a plurality of first mating portions 32, which are spaced apart along the extending direction of the support recess 31. The end of the abutment structure 20 facing the support recess 31 has a second mating portion 23. The first mating portion 32 and the second mating portion 23 are slidably engaged along the extending direction from the second end to the first end. The first mating portion 32 and the second mating portion 23 are also engaged in a snap-fitting manner along the extending direction from the first end to the second end, thereby limiting and stopping the second mating portion 23. Thus, the sliding engagement of the first mating portion 32 and the second mating portion 23 along the direction 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 its abutment position, achieving abutment with the wire harness 3 passing through the wire recess 15, and ensuring the tautness and reliability of the wire harness 3. Meanwhile, during the process of the abutting structure 20 abutting against the wire harness 3 and tightening the wire harness 3, the engaging engagement of the first mating part 32 and the second mating part 23 along the direction from the first end to the second end ensures that the abutting structure 20 can continuously and stably abut against the wire harness 3, preventing slippage of the abutting structure 20 and thus avoiding loosening of the wire harness 3. This further ensures the tightness reliability of the wire harness 3, improves the quality of the motor stator, and enhances the abutting reliability and stability of the abutting structure 20. Furthermore, the arrangement of multiple first mating parts 32 allows the abutting position of the abutting structure 20 to be adjusted according to the requirements of stators of different specifications and sizes, accommodating wire harnesses 3 with varying degrees of looseness. This expands the range of abutting positions, improves the versatility of the abutting structure 20, and consequently enhances the versatility of the frame assembly. Meanwhile, the arrangement of the first mating part 32 and the second mating part 23 enables the abutting structure 20 to have the function of unidirectional movement and reverse locking. The operator only needs to push the abutting structure 20 to slide towards the wire harness 3 to achieve the pushing of the abutting structure 20. No additional fasteners are required, which simplifies the operator's operation steps, reduces the difficulty of the operator's work, improves the operator'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 a side of the first recess 311 away from the wire-passing recess 15. The inner wall of the first recess 311 has a plurality of first mating portions 32. The abutting structure 20 includes a first abutting portion 21 and a second abutting portion 22 that are connected to each other. The first abutting portion 21 extends into the first recess 311, and the second abutting portion 22 extends into the second recess 312. The first abutting portion 21 has a second mating portion 23. Among them, the opening of the first recess 311 is larger than the opening of the second recess 312, so that the inner wall of the second recess 312 limits and stops the first abutting 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 one 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, 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, enabling the staff to push the abutting structure 20 by pushing the second abutting portion 22, achieving the smoothness and reliability of the switching of the abutting structure 20 from the initial position to the abutting position. At the same time, the above setting realizes the limiting and stopping of the abutting structure 20 through the inner wall of the second recess 312, avoiding 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 enhancing the structural compactness and miniaturization design of the skeleton assembly.

[0049] In this embodiment, the second mating 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] As Figure 3 、 Figure 4 and Figure 6 shown, the skeleton assembly further includes a limiting structure 40. The limiting structure 40 is provided on the inner wall of the support recess 31. The limiting structure 40 is located on a side of the plurality of first mating portions 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 a part of the second mating portions 23 to limit and stop the abutting structure 20. In this way, when the staff pushes the abutting structure 20 to slide from the initial position to the abutting position, the limiting structure 40 can abut against the second mating portion 23, determining the maximum movement range of the abutting structure 20, preventing the abutting structure 20 from coming out of the end of the support recess 31 due to excessive adjustment, resulting in damage to the abutting structure 20, and ensuring the operation reliability and safety of the abutting structure 20.

[0052] As Figure 7As shown, the second mating part 23 also includes a stop section 231 and a locking section 232 connected to each other. The stop section 231 abuts against the limiting structure 40, and the locking section 232 engages with the first mating part 32. In this way, the second mating part 23 achieves abutment contact with the limiting structure 40 through the stop section 231, ensuring that the limiting structure 40 can prevent the abutment structure 20 from continuing to move, thus ensuring the operational safety and reliability of the abutment structure 20. Simultaneously, the second mating part 23 achieves locking engagement with the first mating part 32 through the locking section 232, ensuring that the first mating part 32 can prevent the abutment structure 20 from sliding away from the wire harness 3, thus ensuring the abutment stability and reliability of the abutment structure 20 in the abutment position. Meanwhile, the arrangement of the stop section 231 and the locking section 232 makes the structure of the second mating part 23 simpler, reducing the processing difficulty for workers and improving their processing efficiency. It also makes the adjustment steps of the abutting structure 20 more intuitive and simple. After the worker pushes the abutting structure 20 to the abutting position, he slightly retracts it so that the locking section 232 engages with the most suitable first mating part 32, thus completing the adjustment of the tension of the wire harness 3. No complicated manual or tool assistance is required, which improves the work efficiency and ease of operation for workers.

[0053] like Figure 7 As shown, the abutment structure 20 also has a clearance groove 25, and the second mating part 23 is located within the clearance groove 25. The clearance groove 25 is used for the insertion of the limiting structure 40. This insertion of the limiting structure 40 into the clearance groove 25 makes the fit between the limiting structure 40 and the abutment structure 20 tighter, reducing the space occupied by the limiting structure 40 and the abutment structure 20, improving the overall structural compactness of the frame assembly, and increasing the space utilization rate of the frame assembly. It also ensures that the limiting structure 40 can accurately insert into the abutment structure 20 and abut against the stop section 231, effectively limiting the movement range of the abutment structure 20 and improving the operational safety of the abutment structure 20. Simultaneously, the way the limiting structure 40 extends into the clearance groove 25 ensures both limiting and stopping the abutment structure 20, as well as 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 part of the stop section 231 is located in the relief groove 25, which facilitates abutment with the limiting structure 40, thereby improving the reliability and convenience of abutment between the limiting structure 40 and the second mating part 23.

[0055] like Figure 2 , Figure 3 and Figure 6As shown, the support structure 30 also has a receiving recess 33, which is used to accommodate at least a portion of the wire harness 3. The inner wall of the receiving recess 33 is arc-shaped. This arrangement of the receiving recess 33 provides a safe accommodating space for the wire harness 3, and provides a certain degree of positioning for the wire harness 3, ensuring the neatness and accuracy of the wire harness 3's routing. Simultaneously, the arc-shaped inner wall of the receiving recess 33 effectively conforms to the shape of the wire harness 3, preventing vibration of the wire harness 3 under external forces that could lead to displacement or wear, ensuring the positional accuracy of the wire harness 3 and extending its service life. Furthermore, it effectively disperses stress on the wire harness 3, preventing localized stress concentration that could damage the wire harness 3, further extending its service life and improving its operational stability.

[0056] Optionally, the inner wall of the recess 33 can also be in the shape of “]”, ">”, etc., to improve the processing flexibility of the recess 33.

[0057] like Figure 2 and Figure 7 As shown, the abutting structure 20 has an abutting recess 24. When the abutting structure 20 is in the abutting position, the abutting recess 24 is used to accommodate at least a portion of the wire harness 3. The inner wall of the abutting recess 24 is arc-shaped. This arrangement of the abutting recess 24 provides a safe accommodating space for the wire harness 3, enabling it to be positioned and abutted, ensuring the reliability of the abutment. Simultaneously, the arc-shaped inner wall of the abutting recess 24 effectively conforms to the shape of the wire harness 3, preventing excessive displacement or wear caused by vibration under external forces, ensuring the positional accuracy of the wire harness 3 and extending its service life. Furthermore, it effectively disperses stress on the wire harness 3, preventing localized stress concentration that could damage the wire harness 3, further extending its service life and improving its operational stability.

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

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

[0060] This application also provides an electric motor, which includes the aforementioned frame assembly.

[0061] Specifically, the motor also includes multiple stator assemblies, which are arranged sequentially around a circle.

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

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

[0064] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0065] The support structure of the skeleton assembly has a winding section and a wire-passing recess. The winding section is used for winding the wire harness, and the wire-passing recess is used for the wound wire harness to pass through. An abutment structure is movably mounted on the support structure, and the abutment structure has 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. Thus, when the stator has a linear chain structure, multiple skeleton assemblies are arranged in a linear chain. The wire harness winds onto the support structure through the support section and passes through the wire-passing recess before winding onto the support structure of the next skeleton assembly, ensuring the continuity of the wire harness winding. 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 winding is completed and multiple skeleton assemblies are spliced ​​into a circle, the distance between two adjacent skeleton assemblies becomes shorter, causing the wire harness passing through the wire-passing recess to loosen. At this time, the abutting structure is in the abutting position, and the abutting structure abuts against the wire harness passing through the wire recess, and pushes the wire harness to make the wire harness taut, avoiding the phenomenon of wire harness loosening, thereby improving the quality of the motor stator, and thus solving the problem of poor quality of motor stator in the prior art.
