Description

Technical Field

[0001] The present invention relates to the technical field of motor equipment, and in particular to a winding structure, a winding machine, a motor and a household appliance. Background Art

[0002] Currently, the conductor enameled wire winding method used in motor manufacturing typically involves winding the wire through a metal winding needle and onto the stator or rotor core. During the winding process, a certain amount of tension is typically applied in the opposite direction of the wire's forward movement to achieve precise winding and maximize the amount of conductor wire available.

[0003] However, there is a certain resistance between the winding needle and the enameled wire, which increases the required pulling force. The enameled wire is affected by the excessive pulling force, resulting in a reduction in cross-sectional area. At the same time, the resistance between the winding needle and the enameled wire hinders the reverse recovery of the enameled wire, causing the enameled wire to become loose during winding, resulting in uneven wire arrangement and crossing, which affects the wire arrangement effect, wastes the effective area of ​​the stator core slot or the rotor core slot, and affects the efficiency of the motor. Summary of the Invention

[0004] The embodiments of the present invention aim to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of an embodiment of the present invention provides a winding structure.

[0006] A second aspect of an embodiment of the present invention provides a winding machine.

[0007] A third aspect of an embodiment of the present invention provides a motor.

[0008] A fourth aspect of the embodiments of the present invention provides a household appliance.

[0009] In view of this, according to the first aspect of an embodiment of the present invention, a winding structure is provided, which is used for a motor, the motor including a winding, the winding including an enameled wire, and the winding structure including: a main body, the main body is provided with a wire passing channel and a receiving groove, the receiving groove is connected to the wire passing channel, and the wire passing channel is used for the enameled wire to pass through; a ball, which is provided in the receiving groove, and a part of the ball is located in the wire passing channel.

[0010] The winding structure provided by the embodiment of the present invention includes a body and a ball. Specifically, the body is provided with a wire passing channel and a receiving groove, and the wire passing channel is communicated with the receiving groove.

[0011] Since balls are provided in the accommodating groove and some of the balls are located in the wire passing channel, when the enameled wire passes through the wire passing channel to be wound on the stator core or the rotor core, the enameled wire contacts the balls. That is to say, the friction between the conductor enameled wire and the winding needle in the related technology is converted into rolling friction, thereby effectively reducing the friction force generated between the winding structure and the enameled wire during the winding process, reducing the tension required for precise arrangement of the enameled wire on the stator core or the rotor core, ensuring the cross-sectional area of ​​the enameled wire, optimizing the arrangement effect, and increasing the number of enameled wires, which is beneficial to improving the efficiency of the motor.

[0012] In some technical solutions, optionally, the number of accommodating grooves is at least two, and along the radial direction of the wire-passing channel, at least two accommodating grooves are respectively located on both sides of the wire-passing channel; wherein, the number of balls is at least two, and at least two balls are respectively arranged in at least two accommodating grooves.

[0013] This technical solution specifies that the number of accommodating grooves is at least two. Specifically, at least two wire passages are located on either side of the wire passage in a radial direction. Because ball bearings are disposed in each of the at least two accommodating grooves, when the enameled wire passes through the wire passage to be wound around the stator core or rotor core, both radial sides of the enameled wire come into contact with the ball bearings. This further reduces friction between the enameled wire and the winding structure, improving the winding performance of the enameled wire.

[0014] In some technical solutions, optionally, at least two accommodating grooves are arranged opposite to each other along the radial direction of the wire passing channel.

[0015] In this technical solution, since at least two accommodating grooves are opposite to each other in the radial direction of the wire passing channel, that is, in the process of the enameled wire passing through the wire passing channel to be wound on the stator core or the rotor core, the radially opposite sides of the enameled wire are in contact with the ball bearings respectively, thereby further reducing the friction between the enameled wire and the winding structure, optimizing the wire arrangement effect of the enameled wire, and improving the motor efficiency.

[0016] In some technical solutions, optionally, the wire passage includes a wire inlet and a wire outlet, and the enameled wire can enter the wire passage from the wire inlet and pass out through the wire outlet; wherein the accommodating groove is configured to be close to the wire outlet.

[0017] In this technical solution, the wire passage is defined to include a wire inlet and a wire outlet. Specifically, when winding the wire, the enameled wire enters the wire passage from the wire inlet and exits from the wire outlet.

[0018] It can be understood that when winding, when there is a certain angle between the enameled wire and the winding structure, the enameled wire bends, so that the friction force of the angle between the enameled wire and the front end of the winding structure (at the wire outlet) forms a blocking force, and when the angle between the enameled wire and the front end of the winding structure is about 90°, the blocking force is relatively large, affecting the winding effect.

[0019] The accommodating groove is close to the wire outlet, that is, a ball bearing is arranged near the wire outlet, which converts the friction between the position near the front end of the winding structure and the enameled wire into rolling friction. This can effectively reduce the blocking force between the enameled wire and the winding structure, thereby reducing the tension required for precise arrangement of the enameled wire on the stator core or rotor core, improving the winding effect and improving the motor efficiency.

[0020] In some technical solutions, optionally, the wire passing channel includes a first channel wall and a second channel wall, the first channel wall is located at the wire outlet, and the second channel wall is located at the wire inlet; wherein, at least one of the first channel wall and the second channel wall is constructed as an arc-shaped wall.

[0021] This technical solution defines a wire passageway comprising a first channel wall and a second channel wall. Specifically, the first channel wall is located at the wire outlet, and the second channel wall is located at the wire inlet. The first channel wall is an arcuate wall, or the second channel wall is an arcuate wall, or both the first channel wall and the second channel wall are arcuate walls. The specific configuration can be determined based on actual needs.

[0022] Since the first channel wall and / or the second channel wall are arc-shaped walls, the friction between the enameled wire and the winding structure can be further reduced during the winding process, thereby improving the winding effect and enhancing the motor efficiency. At the same time, scratching of the enameled wire can be avoided, which is beneficial to improving the reliability of the motor.

[0023] In some technical solutions, optionally, the main body includes a first winding part and a second winding part, wherein the first winding part is provided with a first groove body, the second winding part is connected to the first winding part, the wire passing channel is provided in at least one of the first winding part and the second winding part, the second winding part is provided with a second groove body, the second groove body is connected to the first groove body, and a receiving groove is formed.

[0024] In this technical solution, it is defined that the main body includes a first winding part and a second winding part. Specifically, the first winding part is provided with a first groove body, the second winding part is provided with a second groove body, and the first winding part and the second winding part are connected so that the first groove body and the second groove body form a receiving groove. In other words, the main body is a split structure formed by the first winding part and the second winding part. Compared with the integrated winding needle in the related art, the manufacturing difficulty of the winding structure can be reduced. At the same time, the main body is a split structure, which can facilitate the installation of the ball, which is conducive to reducing the installation difficulty of the winding structure and improving the installation efficiency of the winding machine.

[0025] Because the ball bearings are disposed within the accommodating grooves, that is, a portion of the ball bearings is located within the first groove body, and a portion of the ball bearings is located within the second groove body. Specifically, as the enameled wire passes through the wire passages to be wound around the stator core or rotor core, the enameled wire and the ball bearings come into contact, effectively reducing friction generated between the winding structure and the enameled wire during the winding process. This reduces the tension required for precise winding of the enameled wire around the stator core or rotor core, optimizes the winding effect, increases the amount of enameled wire, and thus contributes to improved motor efficiency.

[0026] In some technical solutions, optionally, the volume of the first trough body is greater than the volume of the second trough body.

[0027] In this technical solution, since the volume of the first trough body is larger than that of the second trough body, that is, the part with more balls is located in the first trough body, and the part with fewer balls is located in the second trough body, during the installation process, the balls can be placed in the first trough body with a larger volume first, and then the first winding part and the second winding part are connected, which is conducive to further reducing the installation difficulty of the winding structure and improving the installation efficiency.

[0028] In some technical solutions, optionally, the first winding part is further provided with a first groove, which is connected to the first groove body; the second winding part is further provided with a second groove, which is connected to the second groove body, and the second groove and the first groove form a wire passing channel.

[0029] In this technical solution, it is defined that the first winding part is also provided with a first groove, and the second winding part is also provided with a second groove, wherein the first groove and the second groove form a wire passing channel, that is, a part of the wire passing channel is provided in the first winding part, and the other part is provided in the second winding part, which is conducive to reducing the processing difficulty of the wire passing channel.

[0030] In addition, since some of the balls are located in the wire passing channel, the enameled wire comes into contact with the balls when it passes through the wire passing channel to be wound on the stator core or the rotor core, and the friction between the conductor enameled wire and the winding needle in the related technology is converted into rolling friction, thereby effectively reducing the friction generated between the winding structure and the enameled wire during the winding process, reducing the tension required for precise arrangement of the enameled wire on the stator core or the rotor core, improving the winding effect, and improving the efficiency of the motor.

[0031] In some technical solutions, optionally, the first winding part is also provided with a limiting groove, which is located on the outside of the accommodating groove along the radial direction of the wire passing channel; the second winding part is provided with a limiting part, which is located in the limiting groove, so that the second winding part is connected to the first winding part.

[0032] In this technical solution, it is defined that the first winding part is also provided with a limiting groove, and the second winding part is provided with a limiting part. Specifically, along the radial direction of the wire passing channel, the limiting groove is located on the outside of the accommodating groove, and the limiting part is located inside the limiting groove. That is to say, the limiting part of the second winding part is installed in the limiting groove of the first winding part. Through the matching limitation between the limiting part and the limiting groove, reliable assembly between the first winding part and the second winding part can be achieved, which is convenient for the installation of the ball and is conducive to further improving the installation efficiency of the winding structure.

[0033] In some technical solutions, optionally, the first winding portion is further provided with an opening, the opening is communicated with the limiting groove, and the limiting portion can slide into the limiting groove from the opening.

[0034] In this technical solution, it is stipulated that the first winding part is also provided with an opening. Specifically, the opening is connected to the limiting groove. When assembling the winding structure, the limiting part of the second winding part can slide into the limiting groove of the first winding part through the opening, thereby realizing rapid assembly between the first winding part and the second winding part. In other words, the limiting groove is a sliding groove, which can further simplify the installation of the winding structure and is conducive to reducing the production cost of the winding structure.

[0035] In some technical solutions, optionally, the first winding part is further provided with a limiting surface, which is located at an end of the limiting groove away from the opening, and along the sliding direction of the limiting part, the limiting part and the limiting surface are abutted.

[0036] In this technical solution, it is defined that the first winding part is also provided with a limiting surface, specifically, the limiting surface is located at the end of the limiting groove away from the opening. Specifically, when the limiting part of the second winding part slides into the limiting groove of the first winding part through the opening, thereby realizing the rapid assembly between the first winding part and the second winding part, in the sliding direction of the limiting part, when the limiting surface and the limiting part are against each other, it means that the second winding part is installed in place, avoiding the excessive sliding of the second winding part and causing the ball to shift, ensuring the rolling friction properties between the enameled wire and the ball, thereby reducing the friction generated between the winding structure and the enameled wire during the winding process, and improving the winding effect.

[0037] In some technical solutions, optionally, the limiting groove includes a first groove wall and a second groove wall. Along the radial direction of the wire-passing channel, the first groove wall is located on the outside of the accommodating groove, one end of the second groove wall is connected to the first groove wall, and the other end of the second groove wall extends obliquely toward the side where the wire-passing channel is located.

[0038] In this technical solution, the limiting groove is defined to include a first groove wall and a second groove wall. Specifically, one end of the second groove wall is connected to the first groove wall, and the other end of the second groove wall extends obliquely toward the side where the wire passing channel is located. That is to say, the angle between the first groove wall and the second groove wall is less than 90°. When the limiting part slides into the limiting groove, the effect of the cooperation and limitation between the limiting part and the limiting groove can be improved, and the connection strength between the first winding part and the second winding part can be improved, which is conducive to ensuring the smooth progress of the winding process.

[0039] In some technical solutions, optionally, the limiting groove includes a first groove wall and a second groove wall connected to each other. Along the radial direction of the wire-passing channel, the first groove wall is located on the outside of the accommodating groove, and the second groove wall is provided with a recess, which is connected to the limiting groove; wherein, the limiting portion is provided with a protrusion, which is located in the recess.

[0040] This technical solution defines another method for coordinating the positioning of the limiting groove and the limiting portion. Specifically, the limiting groove includes a first groove wall and a second groove wall connected to each other, wherein the second groove wall is provided with a recess, and the limiting portion is provided with a protrusion, and the protrusion is located within the recess. In other words, on the basis of the limiting portion sliding into the limiting groove to achieve cooperative positioning, the protrusion and the recess are additionally provided to further enhance the connection strength between the first winding portion and the second winding portion, which is conducive to ensuring the smooth progress of the winding process.

[0041] In some technical solutions, optionally, at least part of the inner wall of the recess is constructed as an arc-shaped wall; or the second groove wall includes a first groove section and a second groove section, the first groove section is located between the first groove wall and the second groove section, and the two ends of the first groove section are respectively connected to the first groove wall and the second groove section, and the first groove section and the second groove section form a recess.

[0042] In this technical solution, since at least a portion of the inner wall of the recess is an arcuate wall, that is, the recess is an arcuate groove, the outer wall of the projection is optionally configured as an arcuate wall so that the shape of the projection matches the recess.

[0043] Alternatively, the second groove wall includes a first groove section and a second groove section, wherein the first groove section is located between the first groove wall and the second groove section, one end of the first groove section is connected to the first groove wall, and the other end of the first groove section is connected to the second groove section, and the first groove section and the second groove section form a recess, that is, the second groove wall is bent outward to form the recess.

[0044] Since the protrusion is located in the recess, that is, on the basis of the limiting part sliding into the limiting groove to achieve matching limitation, the matching of the protrusion and the recess is added to further enhance the connection strength between the first winding part and the second winding part, which is conducive to ensuring the smooth progress of the winding process.

[0045] In some technical solutions, optionally, the ball includes a steel ball; and / or the body includes a tungsten steel piece.

[0046] In this technical solution, since the main body is a tungsten steel part, that is, the main body is a metal part containing tungsten steel, it can be understood that the tungsten steel part has a lower friction coefficient. In the process of the enameled wire passing through the wire channel to be wound on the stator core or the rotor core, the friction between the enameled wire and the winding structure can be further reduced.

[0047] According to a second aspect of the present invention, a winding machine is provided, comprising a winding structure as provided by any of the above technical solutions, thereby possessing all the beneficial technical effects of the winding structure, which will not be described in detail here.

[0048] According to a third aspect of the present invention, a motor is provided, comprising a stator, the stator comprising a stator core; a rotor, the rotor comprising a rotor core; a winding, the winding comprising an enameled wire, the enameled wire being wound on the stator core or the rotor core by a winding structure as provided in any of the above technical solutions or a winding machine as provided in any of the above technical solutions, thereby possessing all the beneficial technical effects of the winding structure or the winding machine, which will not be repeated here.

[0049] According to a fourth aspect of the present invention, there is provided a household appliance comprising a motor as provided by any of the above technical solutions, thereby having all the beneficial technical effects of the motor, which will not be described in detail here.

DETAILED DESCRIPTION

[0070] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0071] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0072] Refer to the following Figures 1 to 16 The winding structure 100, winding machine, motor and household appliance provided according to some embodiments of the present invention are described.

[0073] In one embodiment according to the present application, Figure 1 、 Figure 5 and Figure 6 As shown, a winding structure 100 is proposed, which is used for a motor. The motor includes a winding, and the winding includes an enameled wire. The winding structure 100 includes: a main body 110, the main body 110 is provided with a wire passage 120 and a receiving groove 130, the receiving groove 130 is connected to the wire passage 120, and the wire passage 120 is used for the enameled wire to pass through; a ball 140, which is provided in the receiving groove 130, and a part of the ball 140 is located in the wire passage 120.

[0074] The winding structure 100 provided in the embodiment of the present invention includes a body 110 and a ball 140 . Specifically, the body 110 is provided with a wire passing channel 120 and a receiving groove 130 , and the wire passing channel 120 is communicated with the receiving groove 130 .

[0075] Since balls 140 are provided in the accommodating groove 130, and part of the balls 140 are located in the wire passing channel 120, when the enameled wire passes through the wire passing channel 120 to be wound on the stator core or the rotor core, the enameled wire contacts the balls 140. That is to say, the friction between the conductor enameled wire and the winding needle in the related technology is converted into rolling friction, thereby effectively reducing the friction generated between the winding structure 100 and the enameled wire during the winding process, reducing the tension required for the precise arrangement of the enameled wire on the stator core or the rotor core, ensuring the cross-sectional area of ​​the enameled wire, optimizing the arrangement effect, and increasing the number of enameled wires, which is beneficial to improving the efficiency of the motor.

[0076] like Figure 1 、 Figure 5 and Figure 6 As shown, in some embodiments, optionally, the number of the accommodating grooves 130 is at least two, and along the radial direction of the wire-passing channel 120, at least two accommodating grooves 130 are respectively located on both sides of the wire-passing channel 120; wherein, the number of the balls 140 is at least two, and at least two balls 140 are respectively arranged in at least two accommodating grooves 130.

[0077] In this embodiment, the number of the accommodating grooves 130 is limited to at least two. Specifically, the at least two wire passages 120 are located on either side of the wire passage 120 in the radial direction. Since the at least two accommodating grooves 130 are respectively provided with balls 140, when the enameled wire passes through the wire passage 120 to be wound around the stator core or the rotor core, both sides of the enameled wire in the radial direction come into contact with the balls 140, thereby further reducing the friction between the enameled wire and the winding structure 100 and improving the winding effect of the enameled wire.

[0078] like Figure 1 、 Figure 5 and Figure 6 As shown, in some embodiments, optionally, at least two accommodating grooves 130 are arranged opposite to each other along the radial direction of the wire-passing channel 120 .

[0079] In this embodiment, since at least two accommodating grooves 130 are opposite to each other in the radial direction of the wire passing channel 120, that is, in the process of the enameled wire passing through the wire passing channel 120 to be wound on the stator core or the rotor core, the radially opposite sides of the enameled wire are in contact with the ball bearings 140 respectively, thereby further reducing the friction between the enameled wire and the winding structure 100, optimizing the wire arrangement effect of the enameled wire, and improving the motor efficiency.

[0080] like Figure 5 and Figure 6As shown, in some embodiments, optionally, the wire passage 120 includes a wire inlet 121 and a wire outlet 122 , and the enameled wire can enter the wire passage 120 from the wire inlet 121 and pass out through the wire outlet 122 ; wherein the accommodating groove 130 is configured to be close to the wire outlet 122 .

[0081] In this embodiment, the wire passage 120 is defined to include a wire inlet 121 and a wire outlet 122 . Specifically, during winding, the enameled wire enters the wire passage 120 from the wire inlet 121 and exits from the wire outlet 122 .

[0082] It can be understood that when winding, when there is a certain angle between the enameled wire and the winding structure 100, the enameled wire bends, so that the friction force of the angle between the enameled wire and the front end of the winding structure 100 (at the outlet 122) forms a blocking force, and when the angle between the enameled wire and the front end of the winding structure 100 is about 90°, the blocking force is relatively large, affecting the winding effect.

[0083] The accommodating groove 130 is close to the wire outlet 122. In other words, the ball bearing 140 is provided near the wire outlet 122. The friction between the position near the front end of the winding structure 100 and the enameled wire is converted into rolling friction. This can effectively reduce the blocking force between the enameled wire and the winding structure 100, thereby reducing the tension required for the enameled wire to be precisely arranged on the stator core or the rotor core, thereby improving the winding effect and the motor efficiency.

[0084] like Figure 5 As shown, in some embodiments, optionally, the wire channel 120 includes a first channel wall 123 and a second channel wall 124, the first channel wall 123 is located at the wire outlet 122, and the second channel wall 124 is located at the wire inlet 121; wherein, at least one of the first channel wall 123 and the second channel wall 124 is constructed as an arc-shaped wall.

[0085] In this embodiment, the wire passage 120 is defined as including a first passage wall 123 and a second passage wall 124. Specifically, the first passage wall 123 is located at the wire outlet 122, and the second passage wall 124 is located at the wire inlet 121. The first passage wall 123 is an arcuate wall, or the second passage wall 124 is an arcuate wall, or both the first passage wall 123 and the second passage wall 124 are arcuate walls. Specific configurations can be made based on actual needs.

[0086] Since the first channel wall 123 and / or the second channel wall 124 are arc-shaped walls, the friction between the enameled wire and the winding structure 100 can be further reduced during the winding process, thereby improving the winding effect and enhancing the motor efficiency. At the same time, scratching of the enameled wire can be avoided, which is beneficial to improving the reliability of the motor.

[0087] In addition, since balls 140 are provided in the accommodating groove 130, and part of the balls 140 are located in the wire passing channel 120, when the enameled wire passes through the wire passing channel 120 to be wound on the stator core or the rotor core, the enameled wire contacts the balls 140. That is to say, the friction between the conductor enameled wire and the winding needle in the related technology is converted into rolling friction, thereby effectively reducing the friction force generated between the winding structure 100 and the enameled wire during the winding process, reducing the tension required for the precise arrangement of the enameled wire on the stator core or the rotor core, ensuring the cross-sectional area of ​​the enameled wire, optimizing the arrangement effect, and increasing the number of enameled wires, which is beneficial to improving the efficiency of the motor.

[0088] like Figure 7 、 Figure 11 、 Figure 12 and Figure 16 As shown, in some embodiments, optionally, the main body 110 includes a first winding portion 111 and a second winding portion 112, wherein the first winding portion 111 is provided with a first groove body 131, and the second winding portion 112 is connected to the first winding portion 111, and the wire passing channel 120 is provided in at least one of the first winding portion 111 and the second winding portion 112, and the second winding portion 112 is provided with a second groove body 132, and the second groove body 132 is connected to the first groove body 131 to form a receiving groove 130.

[0089] In this embodiment, it is defined that the main body 110 includes a first winding part 111 and a second winding part 112. Specifically, the first winding part 111 is provided with a first groove body 131, and the second winding part 112 is provided with a second groove body 132. The first winding part 111 and the second winding part 112 are connected so that the first groove body 131 and the second groove body 132 form a receiving groove 130. In other words, the main body 110 is a split structure formed by the first winding part 111 and the second winding part 112. Compared with the integrated winding needle in the related art, the manufacturing difficulty of the winding structure 100 can be reduced. At the same time, the main body 110 is a split structure, which can facilitate the installation of the ball 140, which is conducive to reducing the installation difficulty of the winding structure 100 and improving the installation efficiency of the winding machine.

[0090] Because the ball 140 is disposed within the accommodating groove 130, that is, a portion of the ball 140 is located within the first groove body 131, and a portion of the ball 140 is located within the second groove body 132. Specifically, when the enameled wire passes through the wire passage 120 to be wound around the stator core or the rotor core, the enameled wire contacts the ball 140, effectively reducing the friction generated between the winding structure 100 and the enameled wire during the winding process, lowering the tension required for precise arrangement of the enameled wire on the stator core or the rotor core, optimizing the arrangement effect, increasing the amount of enameled wire, and thereby improving motor efficiency.

[0091] The wire passage 120 is provided in the first winding portion 111, or the wire passage 120 is provided in the second winding portion 112, or a portion of the wire passage 120 is provided in the first winding portion 111 and the other portion is provided in the second winding portion 112. Specific arrangements can be made according to actual needs.

[0092] In some embodiments, optionally, the volume of the first slot body 131 is greater than the volume of the second slot body 132 .

[0093] In this embodiment, since the volume of the first groove body 131 is larger than the volume of the second groove body 132, that is, the larger part of the ball 140 is located in the first groove body 131, and the smaller part is located in the second groove body 132. During the installation process, the ball 140 can be placed in the first groove body 131 with a larger volume first, and then the first winding part 111 and the second winding part 112 are connected, which is conducive to further reducing the installation difficulty of the winding structure 100 and improving the installation efficiency.

[0094] like Figure 7 、 Figure 11 、 Figure 12 and Figure 16 As shown, in some embodiments, optionally, the first winding portion 111 is further provided with a first groove 125, which is connected to the first groove body 131; the second winding portion 112 is further provided with a second groove 126, which is connected to the second groove body 132, and the second groove 126 and the first groove 125 form a wire passing channel 120.

[0095] In this embodiment, it is defined that the first winding portion 111 is further provided with a first groove 125, and the second winding portion 112 is further provided with a second groove 126, wherein the first groove 125 and the second groove 126 form a wire passing channel 120, that is, a part of the wire passing channel 120 is provided in the first winding portion 111, and the other part is provided in the second winding portion 112, which is conducive to reducing the processing difficulty of the wire passing channel 120.

[0096] In addition, since part of the ball bearings 140 is located in the wire passing channel 120, when the enameled wire passes through the wire passing channel 120 to be wound on the stator core or the rotor core, the enameled wire contacts the ball bearings 140, and the friction between the conductor enameled wire and the winding needle in the related technology is converted into rolling friction, thereby effectively reducing the friction force generated between the winding structure 100 and the enameled wire during the winding process, reducing the tension required for the enameled wire to be precisely arranged on the stator core or the rotor core, improving the winding effect, and improving the motor efficiency.

[0097] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 12 As shown, in some embodiments, optionally, the first winding portion 111 is further provided with a limiting groove 150, and along the radial direction of the wire passage 120, the limiting groove 150 is located on the outside of the accommodating groove 130; the second winding portion 112 is provided with a limiting portion 160, and the limiting portion 160 is located in the limiting groove 150, so that the second winding portion 112 is connected to the first winding portion 111.

[0098] In this embodiment, it is defined that the first winding portion 111 is further provided with a limiting groove 150, and the second winding portion 112 is provided with a limiting portion 160. Specifically, along the radial direction of the wire passing channel 120, the limiting groove 150 is located on the outside of the accommodating groove 130, and the limiting portion 160 is located in the limiting groove 150. That is to say, the limiting portion 160 of the second winding portion 112 is installed in the limiting groove 150 of the first winding portion 111. Through the matching limitation between the limiting portion 160 and the limiting groove 150, reliable assembly between the first winding portion 111 and the second winding portion 112 can be achieved, which facilitates the installation of the ball 140 and helps to further improve the installation efficiency of the winding structure 100.

[0099] Optionally, the shape of the limiting portion 160 matches that of the limiting groove 150 .

[0100] like Figure 11 As shown, in some embodiments, optionally, the first winding portion 111 is further provided with an opening 113 , the opening 113 is communicated with the limiting groove 150 , and the limiting portion 160 can slide into the limiting groove 150 from the opening 113 .

[0101] In this embodiment, it is defined that the first winding portion 111 is also provided with an opening 113. Specifically, the opening 113 is connected to the limiting groove 150. When assembling the winding structure 100, the limiting portion 160 of the second winding portion 112 can slide into the limiting groove 150 of the first winding portion 111 through the opening 113, thereby realizing rapid assembly between the first winding portion 111 and the second winding portion 112. That is to say, the limiting groove 150 is a sliding groove, which can further simplify the installation of the winding structure 100 and help reduce the production cost of the winding structure 100.

[0102] like Figure 11 As shown, in some embodiments, optionally, the first winding portion 111 is further provided with a limiting surface 114 , which is located at one end of the limiting groove 150 away from the opening 113 , and along the sliding direction of the limiting portion 160 , the limiting portion 160 abuts against the limiting surface 114 .

[0103] In this embodiment, it is defined that the first winding portion 111 is further provided with a limiting surface 114. Specifically, the limiting surface 114 is located at one end of the limiting groove 150 away from the opening 113. Specifically, when the limiting portion 160 of the second winding portion 112 slides into the limiting groove 150 of the first winding portion 111 through the opening 113, thereby realizing the quick assembly between the first winding portion 111 and the second winding portion 112, in the sliding direction of the limiting portion 160, when the limiting surface 114 and the limiting portion 160 are against each other, it indicates that the second winding portion 112 is installed in place at this time, avoiding excessive sliding of the second winding portion 112 and causing the ball 140 to shift, ensuring the rolling friction properties between the enameled wire and the ball 140, thereby reducing the friction generated between the winding structure 100 and the enameled wire during the winding process, and improving the winding effect.

[0104] In addition, since balls 140 are provided in the accommodating groove 130, and part of the balls 140 are located in the wire passing channel 120, when the enameled wire passes through the wire passing channel 120 to be wound on the stator core or the rotor core, the enameled wire contacts the balls 140. That is to say, the friction between the conductor enameled wire and the winding needle in the related technology is converted into rolling friction, thereby effectively reducing the friction force generated between the winding structure 100 and the enameled wire during the winding process, reducing the tension required for the precise arrangement of the enameled wire on the stator core or the rotor core, ensuring the cross-sectional area of ​​the enameled wire, optimizing the arrangement effect, and increasing the number of enameled wires, which is beneficial to improving the efficiency of the motor.

[0105] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, in some embodiments, optionally, the limiting groove 150 includes a first groove wall 151 and a second groove wall 152. Along the radial direction of the wire-passing channel 120, the first groove wall 151 is located on the outside of the accommodating groove 130, one end of the second groove wall 152 is connected to the first groove wall 151, and the other end of the second groove wall 152 extends obliquely toward the side where the wire-passing channel 120 is located.

[0106] In this embodiment, the limiting groove 150 is defined to include a first groove wall 151 and a second groove wall 152. Specifically, one end of the second groove wall 152 is connected to the first groove wall 151, and the other end of the second groove wall 152 extends obliquely toward the side where the wire channel 120 is located. That is to say, the angle between the first groove wall 151 and the second groove wall 152 is less than 90°. When the limiting portion 160 slides into the limiting groove 150, the effect of the cooperation and limitation between the limiting portion 160 and the limiting groove 150 can be improved, and the connection strength between the first winding portion 111 and the second winding portion 112 can be improved, which is conducive to ensuring the smooth progress of the winding process.

[0107] In addition, since balls 140 are provided in the accommodating groove 130, and part of the balls 140 are located in the wire passing channel 120, when the enameled wire passes through the wire passing channel 120 to be wound on the stator core or the rotor core, the enameled wire contacts the balls 140. That is to say, the friction between the conductor enameled wire and the winding needle in the related technology is converted into rolling friction, thereby effectively reducing the friction force generated between the winding structure 100 and the enameled wire during the winding process, reducing the tension required for the precise arrangement of the enameled wire on the stator core or the rotor core, ensuring the cross-sectional area of ​​the enameled wire, optimizing the arrangement effect, and increasing the number of enameled wires, which is beneficial to improving the efficiency of the motor.

[0108] like Figure 3 、 Figure 4 、 Figure 9 、 Figure 10 、 Figure 14 and Figure 15 As shown, in some embodiments, optionally, the limiting groove 150 includes a first groove wall 151 and a second groove wall 152 connected to each other. Along the radial direction of the wire-passing channel 120, the first groove wall 151 is located on the outside of the accommodating groove 130, and the second groove wall 152 is provided with a recess 153, which is connected to the limiting groove 150; wherein, the limiting portion 160 is provided with a protrusion 161, which is located in the recess 153.

[0109] In this embodiment, another limiting cooperation mode of the limiting groove 150 and the limiting portion 160 is defined. Specifically, the limiting groove 150 includes a first groove wall 151 and a second groove wall 152 connected to each other, wherein the second groove wall 152 is provided with a recess 153, and the limiting portion 160 is provided with a protrusion 161, and the protrusion 161 is located in the recess 153. In other words, on the basis of the limiting portion 160 sliding into the limiting groove 150 to achieve the cooperation and limitation, the protrusion 161 and the recess 153 are additionally provided to further enhance the connection strength between the first winding portion 111 and the second winding portion 112, which is conducive to ensuring the smooth progress of the winding process.

[0110] In addition, since balls 140 are provided in the accommodating groove 130, and part of the balls 140 are located in the wire passing channel 120, when the enameled wire passes through the wire passing channel 120 to be wound on the stator core or the rotor core, the enameled wire contacts the balls 140. That is to say, the friction between the conductor enameled wire and the winding needle in the related technology is converted into rolling friction, thereby effectively reducing the friction force generated between the winding structure 100 and the enameled wire during the winding process, reducing the tension required for the precise arrangement of the enameled wire on the stator core or the rotor core, ensuring the cross-sectional area of ​​the enameled wire, optimizing the arrangement effect, and increasing the number of enameled wires, which is beneficial to improving the efficiency of the motor.

[0111] like Figure 3 、 Figure 4 、 Figure 9 、 Figure 10 、 Figure 14 and Figure 15 As shown, in some embodiments, optionally, at least part of the inner wall of the recess 153 is constructed as an arc-shaped wall; or the second groove wall 152 includes a first groove section 154 and a second groove section 155, the first groove section 154 is located between the first groove wall 151 and the second groove section 155, and the two ends of the first groove section 154 are respectively connected to the first groove wall 151 and the second groove section 155, and the first groove section 154 and the second groove section 155 form a recess 153.

[0112] In this embodiment, since at least a portion of the inner wall of the recess 153 is an arcuate wall, that is, the recess 153 is an arcuate groove, the outer wall of the protrusion 161 is optionally configured as an arcuate wall so that the shape of the protrusion 161 matches that of the recess 153 .

[0113] Alternatively, the second groove wall 152 includes a first groove section 154 and a second groove section 155, wherein the first groove section 154 is located between the first groove wall 151 and the second groove section 155, one end of the first groove section 154 is connected to the first groove wall 151, and the other end of the first groove section 154 is connected to the second groove section 155, and the first groove section 154 and the second groove section 155 form a recess 153, that is, the second groove wall 152 is bent outward to form the recess 153.

[0114] Since the protrusion 161 is located in the recess 153, that is, on the basis of the limiting portion 160 sliding into the limiting groove 150 to achieve the matching limit, the matching of the protrusion 161 and the recess 153 is added to further enhance the connection strength between the first winding portion 111 and the second winding portion 112, which is conducive to ensuring the smooth progress of the winding process.

[0115] In some embodiments, optionally, the ball 140 comprises a steel ball; and / or the body 110 comprises a tungsten steel piece.

[0116] In this embodiment, since the main body 110 is a tungsten steel part, that is, the main body 110 is a metal part containing tungsten steel, it can be understood that the tungsten steel part has a lower friction coefficient. When the enameled wire passes through the wire channel 120 to be wound on the stator core or the rotor core, the friction between the enameled wire and the winding structure 100 can be further reduced.

[0117] Optionally, the tungsten steel part includes YG20 (die steel).

[0118] like Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 11 、 Figure 12 and Figure 16 As shown, in a specific embodiment, optionally, a motor winding needle product (winding structure 100) is provided, wherein the motor winding needle (winding structure 100) is composed of two metal sheets (a first winding portion 111 and a second winding portion 112) and a ball 140. The two metal sheets are slidably assembled through a dovetail groove (limiting groove 150). There is a circular hole (wire passage 120) in the middle of the two metal sheets, through which enameled wire and other wires can pass. At the front end of the two metal sheets (wire outlet 122), the ball 140 is placed in a specially designed ball groove (accommodating groove 130). When the enameled wire and other wires pass through the ball 140, the friction between the winding needle (winding structure 100) and the wire is reduced to a certain extent, which can effectively improve the winding effect of the motor stator, thereby improving the motor efficiency.

[0119] The present invention is different from the one-piece winding needle in the related art. It is composed of two metal sheets, which are limited by a slide groove (limiting groove 150). Each of the two metal sheets has two hemispherical recessed holes (the first groove body 131 and the second groove body 132), which can be used to place steel balls (ball bearings 140). The enameled wire passes through the winding needle (winding structure 100) designed by the present invention, and the steel balls (ball bearings 140) at the front end (near the wire outlet 122) can convert the sliding friction in the related art into rolling friction, thereby further reducing the friction force. At the same time, the angular friction between the enameled wire and the front end of the winding needle (winding structure 100) can reduce the blocking force due to the rolling properties of the steel balls.

[0120] The winding needle (winding structure 100) designed in the present invention reduces the friction between the enameled wire and the winding needle (winding structure 100), thereby reducing the tension required for precise arrangement of the enameled wire on the stator core or rotor core. This allows for tight arrangement of the wire on the winding machine, optimizes the arrangement effect, and increases the amount of conductive enameled wire.

[0121] Before winding the stator or rotor, the upper and lower pieces (the first winding part 111 and the second winding part 112) of the winding needle (winding structure 100) and the steel balls (ball bearings 140) are combined through the slide groove (limiting groove 150), and the integrated winding needle of the winding machine in the related art is replaced with the ball winding needle (winding structure 100) of the present invention. The speed parameters and tension parameters of the equipment are set reasonably, and the conductor enameled wire passes through the enameled wire slideway (wire passage 120) of the winding needle (winding structure 100) and is wound according to the product winding method requirements.

[0122] According to a second aspect of the present invention, a winding machine is provided, comprising the winding structure 100 provided in any of the above embodiments, thereby having all the beneficial technical effects of the winding structure 100, which will not be repeated here.

[0123] According to a third aspect of the present invention, a motor is provided, comprising a stator, the stator comprising a stator core; a rotor, the rotor comprising a rotor core; a winding, the winding comprising an enameled wire, the enameled wire being wound on the stator core or the rotor core by a winding structure 100 as provided in any of the above embodiments or a winding machine as provided in any of the above embodiments, thereby possessing all the beneficial technical effects of the winding structure 100 or the winding machine, which will not be repeated here.

[0124] Since balls 140 are provided in the accommodating groove 130, and part of the balls 140 are located in the wire passing channel 120, when the enameled wire passes through the wire passing channel 120 to be wound on the stator core or the rotor core, the enameled wire contacts the balls 140. That is to say, the friction between the conductor enameled wire and the winding needle in the related technology is converted into rolling friction, thereby effectively reducing the friction generated between the winding structure 100 and the enameled wire during the winding process, reducing the tension required for the precise arrangement of the enameled wire on the stator core or the rotor core, ensuring the cross-sectional area of ​​the enameled wire, optimizing the arrangement effect, and increasing the number of enameled wires, which is beneficial to improving the efficiency of the motor.

[0125] According to a fourth aspect of the present invention, there is provided a household appliance comprising a motor as provided in any of the above embodiments, thereby possessing all the beneficial technical effects of the motor, which will not be described in detail here.

[0126] Optionally, the household appliances include air conditioners, refrigerators, freezers, blenders, and the like.

[0127] In this specification, the terms "connect," "install," and "fix" should be understood broadly. For example, "connect" can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0128] Throughout this specification, terms such as "one embodiment," "some embodiments," and "specific embodiments" mean that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, schematic representations of these terms do not necessarily refer to the same embodiment or example.

Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
