Description

[0002] As an important power output device, the motor is widely used in machine tools and various control systems. The motor usually includes a stator and a rotor. For the stator structure, its common types are block core type and tooth yoke separation type. In the tooth yoke separation structure, the stator teeth extend into the insulating frame, the winding is wound on the winding frame of the insulating frame, and the stator yoke is sleeved outside the insulating frame. However, affected by the processing technology and processing accuracy, part of the wire on the completed winding may extend out of the gap between two adjacent winding frames and be exposed. Therefore, in the process of mutual sleeve of the stator yoke, the insulating frame and the stator teeth, the yoke may scratch the insulating paint of the wire, causing the wire to be connected to the stator yoke, and even the wire may be pushed out of the gap between adjacent winding frames by the yoke, resulting in the scrapping of the stator, increasing production costs and reducing production efficiency.

[0043] In order to more clearly understand the above-mentioned purpose, 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 the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0044] like Figure 1 and Figure 2 As shown, the present invention provides an insulating skeleton, which can be applied to a stator, and in the process of assembling the stator, the insulating skeleton is fitted with the yoke 2. The insulating skeleton includes a first winding frame and a second winding frame, the first winding frame includes a first winding body and an outer packaging portion 12, and in the use of the insulating skeleton, the winding 3 can be wound and installed on the first winding body; at the same time, along the radial direction of the insulating skeleton (or the radial direction of the stator), the outer packaging portion 12 is arranged on the outside of the first winding body and connected to the first winding body; accordingly, the second winding frame includes a second winding body and an inner packaging portion 13, and the winding 3 can also be wound and installed on the second winding body, and along the radial direction of the insulating skeleton, the inner packaging portion 13 is connected to the outside of the second winding body. During the assembly of the first winding frame and the second winding frame, the two are adjacent to each other, and in the radial direction of the insulating skeleton, the outer packaging portion 12 is located outside the inner packaging portion 13, and at least a part of the positive projection of the outer packaging portion 12 along the radial direction of the insulating skeleton can be located on the inner packaging portion 13.

[0045] Specifically, the insulating skeleton can be composed of only the first winding frame and the second winding frame, both of which can be semicircular structures. Preferably, in addition to the first winding frame and the second winding frame, the insulating skeleton also includes other winding frames; or, the first winding frame and the second winding frame are provided with multiple, and then the multiple first winding frames and the multiple second winding frames together form an insulating skeleton with a cylindrical structure. More specifically, the structure and size of the first winding body and the second winding body can correspond to each other to ensure that the same winding 3 has basically the same effect after being respectively wound and installed on the first winding body and the second winding body. Therefore, the first winding body and the second winding body can be collectively referred to as the winding body 11; the winding body 11 can be made of insulating materials such as plastic. The outer packaging part 12 and the inner packaging part 13 can also be made of insulating materials such as plastic. In order to prevent the size of the entire insulating skeleton from increasing due to the provision of the outer packaging part 12 and the inner packaging part 13, which in turn causes the yoke 2 to be unable to be sleeved outside the insulating skeleton, optionally, the inner packaging part 13 can be a retracted concave structure, so that after the outer packaging part 12 is stacked on the outside of the inner packaging part 13, it can still ensure that the yoke 2 and other structures can be normally sleeved and installed outside the insulating skeleton. Alternatively, it is also possible to simultaneously reduce the thickness of the stacked parts of the inner packaging part 13 and the outer packaging part 12, so that after the insulating skeleton is assembled, the stacked inner packaging part 13 and the outer packaging part 12 will not increase the original size of the insulating skeleton, and ensure that the yoke 2 and other structures can be normally sleeved outside the insulating skeleton. It should be noted that the direction along which the outer packaging part 12 forms a projection is the diameter direction of the insulating skeleton, which is also the radial direction of the stator; at the same time, this direction is also the thickness direction of the outer packaging part 12 in the usual sense. In addition, the straight line in this direction also intersects with the outer packaging part 12 and passes through the center of the outer packaging part 12.

[0046] Optionally, both the outer packaging part 12 and the inner packaging part 13 can be arc-shaped structures, and the two can fit together; or, in the radial direction of the insulating skeleton, a gap of a certain size can be provided between the outer packaging part 12 and the inner packaging part 13. When the outer packaging part 12 and the inner packaging part 13 fit together, the fitting surfaces of the two can be an arc-shaped structure, or a planar structure, or the fitting surfaces of the two can also be a stepped structure. Of course, the fitting surfaces of the two can also be other irregular structures. In addition, when there is a gap between the outer packaging part 12 and the inner packaging part 13, the structures of the relative surfaces of the two can be arbitrarily selected and are not limited here.

[0047] As described above, the insulating skeleton provided by the present invention can be applied to structures such as stators, which can be installed in the yoke 2 of the stator. The insulating skeleton includes a first winding frame and a second winding frame, an outer packaging portion 12 is provided on the first winding frame, and an inner packaging portion 13 is provided on the second winding frame. At least a part of the radial projection of the outer packaging portion 12 along the insulating skeleton is located on the inner packaging portion 13, that is, there are mutually overlapping parts between the outer packaging portion 12 and the inner packaging portion 13, so that the windings 3 on the first winding body and the second winding body can be packaged to prevent the wires of the windings 3 from being exposed, and further ensure that in the process of the yoke 2 being mounted on the insulating skeleton, the yoke 2 will not scratch the wires, nor will the wires be pushed out from between the first winding portion and the second winding portion, thereby ensuring that the assembled stator can work normally, improving production efficiency and reducing production costs.

[0048] Considering that there is a gap between the outer packaging part 12 and the inner packaging part 13, the wire of the winding 3 wound on the winding body 11 may still leak out from the aforementioned gap. Figure 3-5 As shown, the outer packaging part 12 and the inner packaging part 13 can be overlapped and connected, thereby further ensuring that the winding 3 can be better packaged and protected by the outer packaging part 12 and the inner packaging part 13, preventing the wire from being scratched by the yoke 2 or even being pushed out of the aforementioned gap during the installation of the yoke 2, thereby further improving the assembly efficiency and yield rate of the stator.

[0049] Specifically, the specific structures of the outer packaging part 12 and the inner packaging part 13 can be flexibly selected according to actual conditions. As described above, the specific structures of the relative fitting surfaces of the two can be planes, curved surfaces or other corresponding structures, which are not specifically limited here.

[0050] Furthermore, if Figure 3 As shown, the outer packaging portion 12 may include a first arc segment 121 and a first straight plate segment 122, and the first arc segment 121 and the first straight plate segment 122 are connected to each other. Correspondingly, the inner packaging portion 13 includes a second arc segment 131 and a second straight plate segment 132, and the second arc segment 131 and the second straight plate segment 132 are connected to each other. In the process of overlapping the outer packaging portion 12 and the inner packaging portion 13, the first straight plate segment 122 and the second straight plate segment 132 can be overlapped with each other. In this case, the connection effect produced when the outer packaging portion 12 and the inner packaging portion 13 are overlapped is relatively good; at the same time, in the radial direction of the insulating skeleton, the first straight plate segment 122 can be retracted relative to the first arc segment 121, and the second straight plate segment 132 can be retracted relative to the second arc segment 131. This can reduce the overall size of the insulating skeleton to a certain extent, so that in the process of mutual insertion of the yoke 2 and the insulating skeleton, the yoke 2 is easier to be inserted onto the insulating skeleton, so as to further reduce the assembly difficulty of the stator and improve the assembly efficiency.

[0051] Specifically, the specific dimensions of the first arc segment 121, the first straight plate segment 122, the second arc segment 131 and the second straight plate segment 132 can be determined according to the actual structure of the insulating skeleton; preferably, the structures of the first arc segment 121 and the second arc segment 131 can be made to correspond to each other, and the structures of the first straight plate segment 122 and the second straight plate segment 132 can be made to correspond to each other, so that in the process of overlapping and matching between the outer packaging part 12 and the inner packaging part 13, the matching relationship between the two is more stable; and further, the use of such a corresponding structure can make the outer packaging part 12 and the inner packaging part 13 have a better protection effect on the winding 3 located on the inner side.

[0052] More specifically, the angles of the first arc segment 121 and the second arc segment 131 can be determined according to the angles spanned by the two, and the thicknesses of the two can be made equal; the thicknesses of the first straight plate segment 122 and the second straight plate segment 132 can be determined according to actual conditions. Preferably, the sum of the thicknesses of the first straight plate segment 122 and the second straight plate segment 132 can be made equal to or slightly greater than the thickness of the first arc segment 121, thereby further ensuring that after the first straight plate segment 122 and the second straight plate segment 132 are overlapped and connected, there will be no obstruction to the assembly of the yoke 2 and the stator teeth; for example, the first straight plate segment 122 and the second straight plate segment 132 can both be flat plate structures, and the thicknesses of the two can be the same.

[0053] Furthermore, if Figure 3 , Figure 4 and Figure 5 As shown, along the direction away from the first arc segment 121, the radial dimension of the first straight plate segment 122 in the insulating skeleton can be gradually reduced, that is, the thickness of the first straight plate segment 122 that is farther away from the first arc segment 121 is smaller; accordingly, the thickness of the second straight plate segment 132 that is farther away from the second arc segment 131 is smaller, so that after the two are overlapped, the total thickness at any position of the combined structure formed is basically equal, so that the overall structural strength at any position can meet the use requirements. Specifically, the structure and size of the first straight plate segment 122 and the second straight plate segment 132 can be made the same, for example, both can be triangular prism structures, so as to overlap with each other.

[0054] Furthermore, if Figure 5As shown, the first straight plate segment 122 has a first plane 1211 and a first inclined surface 1212, the first plane 1211 and the first inclined surface 1212 are connected to each other, and both are connected to the first arc segment 121. In the process of designing and producing the first straight plate segment 122, the structure of the entire first straight plate segment 122 can be changed so that the straight line where the diameter of the insulating skeleton is located intersects and is perpendicular to the first plane 1211. In this case, the first straight plate segment 122 can be a triangular prism structure, and the cross section of the first straight plate segment 122 is a right triangle. By making an adaptive change to the second straight plate segment 132, the thickness of any position on the combined structure formed by the two when overlapped with each other can be basically equal, and the thickness of the aforementioned combined structure can be basically equal to the thickness of the first arc segment 121 by changing the overlap state of the two, so as to further ensure that the structural strength of any part of the entire insulating skeleton can meet the requirements.

[0055] Specifically, the angle between the first plane 1211 and the first inclined surface 1212 can be determined according to actual needs. The larger the angle between the first plane 1211 and the first inclined surface 1212, the less the overlapped and overlapping parts between the outer packaging part 12 and the inner packaging part 13, and the structural strength and stability of the outer packaging part 12 and the inner packaging part 13 are relatively high; on the contrary, the smaller the angle between the first plane 1211 and the first inclined surface 1212, the more the overlapped and overlapping parts between the outer packaging part 12 and the inner packaging part 13, and the packaging effect produced for the winding 3 is relatively good. Those skilled in the art can flexibly select according to actual needs. Optionally, the angle between the first plane 1211 and the first inclined surface 1212 can be selected within 30°-45°, so as to ensure that the outer packaging part 12 and the inner packaging part 13 have the structural strength that meets the requirements, and the packaging effect of the winding 3 is also good.

[0056] In order to further reduce the processing difficulty of the entire insulating skeleton and improve the processing efficiency, preferably, Figure 1 and 2As shown, the structures of the first winding frame and the second winding frame can be made the same. In this case, the first winding frame and the second winding frame can be collectively referred to as winding frames 1. In this case, one side of the opposite sides of the winding frame 1 is provided with an outer packaging portion 12, and the other side is provided with an inner packaging portion 13. The entire insulating skeleton includes a plurality of winding frames 1, and the plurality of winding frames 1 are arranged along the circumference of the insulating skeleton. In the process of assembling the insulating skeleton, along the circumference of the insulating skeleton, the inner packaging portion 13 of the upper winding frame 1 and the outer packaging portion 12 of the next winding frame 1 are overlapped with each other, so that the plurality of winding frames 1 are overlapped and connected together in sequence in this way to form the entire insulating skeleton. In this case, any two adjacent ones of the multiple winding frames 1 can provide packaging and protection for the winding 3, and then the multiple external packaging parts 12 and the multiple internal packaging parts 13 cooperate with each other to provide packaging and protection for all windings 3 in the stator, thereby ensuring that the yoke 2 will not scratch any wire on the winding 3 during the process of mutual insertion of the yoke 2 with the insulating frame, and can further increase the difficulty of insertion between the yoke 2 and the insulating frame, thereby improving the assembly effect of the stator and other structures.

[0057] Furthermore, if Figure 1 and Figure 3 As shown, in the circumferential direction of the insulating frame, the winding span of the first winding body, that is, the winding body 11 is L, and the width of the portion where the first straight plate segment 122 and the second straight plate segment 132 overlap each other is a, that is, the width of the portion where the orthographic projection of the first straight plate segment 122 along the radial direction of the insulating frame is located on the second straight plate segment 132. Preferably, the relationship between a and L can be:

[0058] 0.0138L-0.0475≤a≤0.0138L+0.0675, and a is made greater than zero to ensure that there is an overlapping portion between the outer packaging portion 12 and the inner packaging portion 13, wherein the units of L and a are both mm.

[0059] It should be noted that if Figure 1 As shown, L is the width of the winding 3 wound on the winding body 11 in the winding frame 1, as shown in FIG. Figure 3 As shown, a is the width of the overlapped and superimposed portion of the outer packaging portion 12 and the inner packaging portion 13. When a and L satisfy the above relationship, the structural strength of each part of the insulating skeleton can meet the use requirements; at the same time, the insulation performance of each part of the insulating skeleton, especially the overlapped portion of the outer packaging portion 12 and the inner packaging portion 13, can also meet the use requirements; in addition, the outer packaging portion 12 and the inner packaging portion 13 can also produce a good packaging protection effect on the winding 3, and can ensure that the yoke 2 can be smoothly mounted on the insulating skeleton.

[0060] Furthermore, the relationship between a and L can be a=0.0138L-0.0325. In this case, after the winding span L of the insulating skeleton is selected, the optimal value of a can be obtained through the above formula. When a takes the aforementioned optimal value, the insulation performance, stiffness and strength of the insulating skeleton can all reach the optimal level, and the packaging effect of the winding 3 is also the best. At the same time, it is also convenient for the structural assembly work of the yoke 2 and other structures.

[0061] Furthermore, if Figure 1 and Figure 2 As shown, the insulating skeleton provided by the present invention may further include an inner baffle 15, which is arranged opposite to the outer packaging portion 12, and the winding body 11 is located between the inner baffle 15 and the outer packaging portion 12. Under the action of the inner baffle 15, the insulating skeleton can be prevented from scratching or squeezing the wire of the winding 3 by the teeth during the process of mutual cooperation with the teeth of the stator.

[0062] Furthermore, if Figure 4 and Figure 5 As shown, a heat dissipation gap 14 can be formed on the outer packaging part 12 and the inner packaging part 13, and a plurality of heat dissipation gaps 14 can be provided, and the plurality of heat dissipation gaps 14 are arranged at intervals, so that after the outer packaging part 12 and the inner packaging part 13 are overlapped and connected to each other, the heat dissipation efficiency of the winding 3 installed on the insulating frame can be improved with the help of the plurality of heat dissipation gaps 14, thereby preventing the overheating of the winding 3 from having an adverse effect on the working performance of the stator and even the motor.

[0063] Specifically, the structure of the heat dissipation gap 14 can be various, such as Figure 5 As shown, the heat dissipation gap 14 can be a rectangular structure, such as Figure 4 As shown, the heat dissipation gap 14 may also be a triangular structure, or a circular structure, etc. Figure 4 As shown, the heat dissipation gap 14 can be a triangular structure. In this case, the outer packaging part 12 and the inner packaging part 13 are both sawtooth structures, and the heat dissipation gaps 14 on the two are arranged relatively, and then after the outer packaging part 12 and the inner packaging part 13 overlap and cooperate with each other, it can be ensured that the heat in the insulation frame can escape through the heat dissipation gap 14, so that the temperature of the winding 3 is relatively low. Figure 5 As shown, the heat dissipation gap 14 can also be a rectangular structure. When the outer packaging part 12 and the inner packaging part 13 of the above-mentioned structural form are adopted, the weight of the entire insulation frame can be effectively reduced, and the comprehensive performance of the motor including the insulation frame can be improved.

[0064] Based on the insulating frame provided by any of the above embodiments, the present invention further provides a motor, which includes a yoke 2, a winding 3 and any of the above insulating frames. During the assembly process of the motor, the winding 3 is installed on the first winding frame and the second winding frame, and the first winding frame and the second winding frame are arranged adjacent to each other, and the yoke 2 is sleeved outside the insulating frame. At the same time, the motor can be used in refrigeration equipment, and the aforementioned refrigeration equipment can specifically be an air conditioner, a refrigerator, a fan, etc., which will not be described in detail here.
