Description

Technical Field

[0001] This utility model relates to the technical field of traction machines, and in particular to a winding structure and a traction machine. Background Technology

[0002] Stator structures typically have a winding structure with multiple layers of conductive coils wound on it. To increase the number of turns of the conductive coils in the winding structure, flat wire vertical winding is generally used. Vertical winding can increase the number of turns in the winding structure, thereby increasing the output power of the winding structure.

[0003] Current methods for vertical winding of flat wire typically involve adding an auxiliary wire-laying mechanism to the winding equipment. This mechanism provides support while winding, resulting in vertical winding. However, existing methods suffer from low slot fill factor and are prone to wire damage due to interference between the wire-blocking mechanism and the frame, requiring space for the mechanism to exit. Furthermore, current methods for vertical winding of flat wire cannot achieve automated and neat wire laying. Summary of the Invention

[0004] The purpose of this invention is to improve the problem that the existing winding structure cannot meet the requirement of automatic vertical winding and neat arrangement of flat wires, and to provide a winding structure and traction machine.

[0005] The technical solutions for achieving the above objectives include the following:

[0006] The winding structure includes:

[0007] A first main body has a first side and a second side, which are disposed opposite to each other; on the first side and the second side, the first main body has a plurality of first grooves;

[0008] Multiple first grooves are equidistantly distributed on the first side and multiple first grooves are equidistantly distributed on the second side; wherein the first grooves on the first side and the first grooves on the second side are staggered.

[0009] In one embodiment, the winding structure further includes a flat wire, which is wound around the first body and at least partially disposed within a first wire groove; the flat wire is wound around the first body to form at least a first winding layer and a second winding layer, the first winding layer and the second winding layer are attached to each other, and the first winding layer is at least partially disposed within a plurality of first wire grooves;

[0010] A second groove is formed between two adjacent flat wires, and the second winding layer is at least partially disposed within a plurality of second grooves;

[0011] The flat wires in the first winding layer and the flat wires in the second winding layer are arranged alternately.

[0012] In one embodiment, the first main body includes a frame, a first side plate, a second side plate, and multiple baffle lines. The first side plate and the second side plate are respectively installed at both ends of the frame, and the multiple baffle lines are installed on both sides of the frame.

[0013] The first groove is formed between two adjacent stop lines, between the first side plate and the stop line, and between the second side plate and the stop line.

[0014] In one embodiment, a groove is formed between the first side plate, the frame, and the second side plate, and the first winding layer and the second winding layer are disposed between the first side plate and the second side plate and installed in the groove.

[0015] In one embodiment, the length of the skeleton is expressed by the formula L = d × (2x - 1);

[0016] Where L is the length of the skeleton; d is the width of the first groove.

[0017] In one embodiment, the winding structure further includes a second main body and two wire members. The first main body is mounted on the second main body, and the two wire members are mounted on the first main body or the second main body. Both wire members are disposed between the first main body and the second main body, and the two wire members are disposed opposite to each other.

[0018] One of the conductors has an inlet and the other conductor has an outlet.

[0019] In one embodiment, the lead wire includes a winding post, a first connecting rod, and a second connecting rod. The winding post is mounted on a first body, the first connecting rod is mounted on a first end of the winding post, and the second connecting rod is mounted on a second end of the winding post. A first winding hole is formed between the first connecting rod and the first body, and a second winding hole is formed between the first connecting rod and the second connecting rod.

[0020] In one embodiment, the total number of turns of the flat wire wound around the first body is expressed by the formula: y = nx - n / 2 (n is an even number) or y = nx - n / 2 + 1 / 2 (n is an odd number);

[0021] Where y is the total number of turns of the flat wire wound around the first main body; n is the number of winding layers; and x is the number of turns of the first winding layer.

[0022] In one embodiment, the depth of the first groove is expressed by the formula 1 / 3H≤h≤2 / 3H;

[0023] Where h is the depth of the first groove and H is the maximum cross-sectional height of the flat wire.

[0024] This utility model also proposes a traction machine, including the winding structure as described above.

[0025] The technical solution provided by this utility model has the following advantages and effects:

[0026] When the flat wire is wound around the first main body and at least partially engaged in the first grooves on the first and second sides, the flat wire is confined within these grooves. The inner wall of the first groove abuts against the outer wall of the flat wire, providing a straightening effect and enabling the flat wire to be wound vertically around the first main body. The first groove also serves to position the flat wire. By using multiple first grooves, this winding structure eliminates the need for an auxiliary wire-laying mechanism for straightening. Furthermore, when designing the first grooves, their width can be equal to the minimum cross-sectional height of the flat wire. When the flat wire is at least partially engaged in the first groove, it is in an upright position outside the first main body. This allows the flat wire to be wound around the first main body in an orderly manner, and the winding mechanism automatically winds the flat wire, achieving a neat and orderly wire-laying effect.

[0037] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0038] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0039] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0040] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.

[0041] This utility model proposes a winding structure 100, such as... Figures 1 to 6 As shown, the device includes a first body 11 and a flat wire 20. The first body 11 has a first side 141 and a second side 142, which are disposed opposite to each other. On the first side 141 and the second side 142, the first body 11 has a plurality of first grooves 101. The plurality of first grooves 101 on the first side 141 are equidistantly distributed, and the plurality of first grooves 101 on the second side 142 are equidistantly distributed. The first grooves 101 on the first side 141 and the first grooves 101 on the second side 142 are staggered. The flat wire 20 is wound around the first body 11 in an orderly manner and is at least partially disposed within the first grooves 101.

[0042] Specifically, the flat wire 20 is wound around the first main body 11 and is at least partially locked in the first wire groove 101 of the first side 141 and the second side 142. The flat wire 20 is restricted in the first wire groove 101 of the first side 141 and the second side 142. The inner wall of the first wire groove 101 abuts against the outer wall of the flat wire 20, which plays a role in straightening the flat wire 20 and realizing the vertical winding of the flat wire 20 outside the first main body 11. The first wire groove 101 has a positioning function for the flat wire 20. By setting multiple first wire grooves 101, the winding structure 100 does not need to use an auxiliary wire laying mechanism for straightening. Moreover, when designing the first wire groove 101, the width of the first wire groove 101 can be equal to the minimum cross-sectional height of the flat wire 20. When the flat wire 20 is at least partially inserted into the first wire groove 101, the flat wire 20 is in a vertical state outside the first body 11. This allows the flat wire 20 to be wound around the first body 11 in an orderly manner. The winding mechanism automatically winds the flat wire 20, achieving the effect of neatly arranging the flat wire 20.

[0043] Furthermore, through Figure 6 It can be seen that the first wire groove 101 on the first side 141 and the first wire groove 101 on the second side 142 are staggered. When the flat wire 20 in the two adjacent first wire grooves 101 is wound to the top outside the first body 11, it can enter the first wire groove 101 at an angle, so as to avoid interference between the flat wires 20 in the two adjacent first wire grooves 101 when they are wound. This arrangement can further improve the effect of neatly arranging the flat wires 20 outside the first body 11.

[0044] In addition, after the first main body 11 is wrapped with multiple layers of winding, the multiple layers of winding are arranged in a grid pattern. Compared with normal flat winding, the top layer of winding has a larger contact area with the air, which makes the heat dissipation of the stator structure better.

[0045] In some embodiments, such as Figure 2 As shown, the flat wire 20 is wound around the first body 11 to form at least a first winding layer 21 and a second winding layer 22. The first winding layer 21 and the second winding layer 22 are attached to each other. The first winding layer 21 is at least partially disposed in a plurality of first wire grooves 101. A second wire groove 102 is formed between two adjacent flat wires 20. The second winding layer 22 is at least partially disposed in a plurality of second wire grooves 102. The flat wires 20 in the first winding layer 21 and the flat wires 20 in the second winding layer 22 are staggered.

[0046] Specifically, when the number of turns of the flat wire 20 around the first body 11 is large, the flat wire 20 forms a first winding layer 21, a second winding layer 22, and a third winding layer around the first body 11. The first winding layer 21 is at least partially disposed within multiple first wire grooves 101, improving the stability of the first winding layer 21 outside the first body 11. On the first winding layer 21 and the second winding layer 22, a second wire groove 102 is formed between two adjacent flat wires 20. The second winding layer 22 is disposed within the second wire groove 102 on the first winding layer 21, and the third winding layer is disposed within the second wire groove 102 on the second winding layer 22.

[0047] pass Figure 2 and Figure 3 It can be seen that the first winding layer 21 and the second winding layer 22 are in a bonded state. Similarly, the second winding layer 22 and the third winding layer are also in a bonded state. Due to the structural shape of the flat wire 20, the lateral area of ​​the flat wire 20 is large, which can increase the contact area between the first winding layer 21, the second winding layer 22, and the third winding layer. Moreover, the adjacent flat wires 20 are arranged closely with very small gaps. When the winding structure 100 is placed in a heating environment, the self-adhesive on the outer wall of the flat wire 20 produces a self-adhesive effect between the two adjacent flat wires 20 in the high-temperature environment, which improves the finishing stability of the first winding layer 21 and the second winding layer 22 outside the first body 11.

[0048] Preferred, such as Figure 4 As shown, the first main body 11 includes a frame 114, a first side plate 112, a second side plate 113, and multiple guide lines 111. The first side plate 112 and the second side plate 113 are respectively installed at both ends of the frame 114, and the multiple guide lines 111 are installed on both sides of the frame 114. A first groove 101 is formed between two adjacent guide lines 111, between the first side plate 112 and the guide line 111, and between the second side plate 113 and the guide line 111. Specifically, by setting multiple guide lines 111, multiple first grooves 101 are formed between the multiple guide lines 111. The inner wall of the guide line 111 is used to abut against the outer wall of the flat line 20. Two adjacent guide lines 111 support the flat line 20, so that the flat line 20 is in an upright state in the first groove 101. The first side plate 112 and the second side plate 113 are also used to straighten the flat line 20 near both ends of the frame 114.

[0049] Preferred, such as Figure 4As shown, a groove is formed between the first side plate 112, the frame 114, and the second side plate 113. The first winding layer 21 and the second winding layer 22 are disposed between the first side plate 112 and the second side plate 113 and installed in the groove. Specifically, the outer edges of the first side plate 112 and the second side plate 113 are positioned higher on the frame 114 than the baffle line 111 is positioned on the frame 114. The first winding layer 21, the second winding layer 22, and the third winding layer can be disposed between the first side plate 112 and the second side plate 113, thereby realizing the arrangement of multiple winding layers 21 outside the first main body 11 and improving the overall stability of the first winding layer 21, the second winding layer 22, and the third winding layer outside the first main body 11.

[0050] In some embodiments, such as Figure 4 As shown, the winding structure 100 also has a second main body 12 and two conductors 15. The first main body 11 is mounted on the second main body 12, and the two conductors 15 are mounted on either the first main body 11 or the second main body 12, with both conductors 15 positioned between the first main body 11 and the second main body 12, and arranged opposite to each other. One conductor 15 has an inlet, and the other conductor 15 has an outlet. Specifically, the two conductors 15 are used to guide the flat wire 20 into the outer surface of the first main body 11, allowing the flat wire 20 to smoothly enter the first wire groove 101. The first end of the flat wire 20 enters from the inlet and winds around the outside of the first main body 11. After winding to a preset number of layers, it is led out from the outlet. The led-out flat wire 20 is welded to the flat wire 20 in the adjacent winding structure 100 or connected to the power supply line.

[0051] Preferred, such as Figure 5 As shown, the conductor 15 includes a winding post 151, a first connecting rod 152, and a second connecting rod 153. The winding post 151 is mounted on the first body 11, the first connecting rod 152 is mounted on the first end of the winding post 151, and the second connecting rod 153 is mounted on the second end of the winding post 151. A first winding hole 154 is formed between the first connecting rod 152 and the first body 11, and a second winding hole 155 is formed between the first connecting rod 152 and the second connecting rod 153. Specifically, the flat wire 20 can enter the first body 11 through the first winding hole 154 or through the second winding hole 155. At the same time, the flat wire 20 can be led out from either the first winding hole 154 or the second winding hole 155. The specific winding process is not particularly limited here.

[0052] In some embodiments, the total number of turns of the flat wire 20 wound around the first body 11 is expressed by the formula: y = nx - n / 2 (n is an even number) or y = nx - n / 2 + 1 / 2 (n is an odd number);

[0053] Where y is the total number of turns of the flat wire 20 wound around the first body 11; n is the number of winding layers; and x is the number of turns of the first winding layer 21.

[0054] Specifically, the total number of turns outside the first main body 11 can be calculated using the formula for calculating the total number of turns outside the first main body 11, based on the total number of winding layers outside the first main body 11. Since there is a direct proportional relationship between the number of turns of the stator coil and the power, the more turns the coil has, the greater the output power of the generator, and vice versa. Therefore, the output power of the winding structure 100 can be obtained through this calculation formula.

[0055] In some embodiments, the length of the skeleton 114 is expressed by the formula L=d×(2x-1);

[0056] Where L is the length of the skeleton 114; d is the width of the first groove 101.

[0057] Specifically, the width of the first groove 101, the width of the second groove 102, and the width of the flat wire 20 are equal. The length of the skeleton 114 can be calculated from the width of the first groove 101 and the number of turns in each winding layer, and the width of the first groove 101 can be deduced from the length of the skeleton 114.

[0058] In some embodiments, the depth of the first groove 101 is expressed by the formula 1 / 3H≤h≤2 / 3H;

[0059] Where h is the depth of the first groove 101, and H is the maximum cross-sectional height of the flat wire 20.

[0060] Specifically, the depth of the first groove 101 is greater than or equal to one-third of the maximum cross-sectional height of the flat wire 20, which allows the flat wire 20 to stand upright within the first groove 101 and also improves the stability of the flat wire 20 within the first groove 101. Conversely, the depth of the first groove 101 is less than or equal to two-thirds of the maximum cross-sectional height of the flat wire 20, which maximizes the contact area between adjacent flat wires 20 on the left and right or top and bottom. When the winding structure 100 is heated, the large contact area outside the flat wire 20 maximizes the self-adhesive effect of the flat wire 20 and further improves the stability of the flat wire 20 outside the first body 11.

[0061] This embodiment also proposes a traction machine, including the above-mentioned winding structure 100. Multiple winding structures 100 are arranged on the base of the traction machine, and the multiple winding structures 100 are part of the stator structure. The winding structure 100 adopts a flat wire 20 vertical winding method. In the same length skeleton 114, the number of turns of flat wire 20 wound on the winding structure 100 is maximized, thereby improving the output power of the traction machine.

[0062] When referencing drawings, new features are explained. To avoid redundant references to drawings that would make the description less concise, features already described will not be referenced again on the drawings if the description is clear.

[0063] The purpose of the above embodiments is to reproduce and derive the technical solution of this utility model by way of example, and to fully describe the technical solution, purpose and effect of this utility model. The purpose is to enable the public to have a more thorough and comprehensive understanding of the disclosed content of this utility model, and it is not intended to limit the protection scope of this utility model.
