[0003] In case the two mounting surfaces are not aligned, the busbars are connected by the following methods. The first method is to first install two busbars on the two mounting surfaces respectively, and then use fasteners to connect the other suspended ends of the two busbars. This method is simple in design, but wastes materials and occupies a large space. The connection between the two busbars affects the temperature rise of the busbar and affects the thermal stability. The second method is to use a busbar to install the two ends of the busbar on the two mounting surfaces respectively through flat bending and vertical bending. However, the flat bending process is difficult to manufacture, and there is still a certain amount of material waste. Summary of the invention

[0046] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0047] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a design and manufacturing method for a twisted busbar, wherein the twisted busbar is connected between two electrical components, the two electrical components respectively have a first mounting surface 1 and a second mounting surface 2, and the two ends of the twisted busbar are respectively mounted on the first mounting surface 1 and the second mounting surface 2.

[0048] The design and manufacturing method of the twisted busbar includes the following steps:

[0049] S1, select a point O1 and a point O2 on the first mounting surface 1 and the second mounting surface 2 respectively; the point O1 and the point O2 can be selected as the center of the first mounting surface 1 and the second mounting surface 2 respectively.

[0050] S2, select the first plane and the second plane, the first plane is parallel to the first mounting surface 1 and the distance between the first plane and the first mounting surface 1 is less than or equal to the thickness of the twisted busbar, the second plane is parallel to the second mounting surface 2 and the distance between the second plane and the second mounting surface 2 is less than or equal to the thickness of the twisted busbar.

[0051] S3, select a point P1 on the first plane, a straight line O1P1 is perpendicular to the first mounting surface 1, select a point P2 on the second plane, a straight line O2P2 is perpendicular to the second mounting surface 2.

[0052] S4, select point A on the first plane, plane P1AB is perpendicular to the first mounting surface 1, select point B on the second plane, plane P2AB is perpendicular to the second mounting surface 2.

[0053] It can be understood that the straight line AB formed by point A and point B is the intersection of plane P1AB and plane P2AB; and point P1, point A, point B and point P2 form a connecting line P1ABP2, which is the skeleton of the twisted busbar, and the angle θ between plane P1AB and plane P2AB is the twisting angle of the twisted busbar.

[0054] S5, design the twisted busbar digital module 3 according to the connection line P1ABP2 and the twist angle θ. It can be understood that the thickness K and width W of the twisted busbar are both known, and the twisted busbar digital module 3 can be designed according to the track of the connection line P1ABP2 and the twist angle θ.

[0055] Step S6, manufacturing the twisted busbar according to the twisted busbar digital model 3.

[0056] Through the design and manufacturing method of the twisted busbar, a twisted busbar digital module 3 can be designed according to the spatial positions of the first mounting surface 1 and the second mounting surface 2, and the structural dimensions are accurate; and the twisted busbar manufactured according to the twisted busbar digital module 3 has no material waste, reduces the occupied space, is simple to process and manufacture, and can ensure the insulation distance; in addition, the twisted busbar is an integrated twisted structure with good thermal stability.

[0057] Before designing the twisted busbar digital model 3, first establish an XYZ three-dimensional coordinate system, and locate the positions of the first mounting surface 1 and the second mounting surface 2 according to the distance deviation between the first mounting surface 1 and the second mounting surface 2 on the X-axis, Y-axis and Z-axis to facilitate subsequent design.

[0058] In step S4, the process of selecting point A is as follows: first, point A is selected in the general direction of the first plane toward the second mounting surface 2, the angle between the straight line P1A and the Y axis is α, and then the angle α is gradually adjusted until the plane P1AB is perpendicular to the first mounting surface 1; the process of selecting point B is as follows: first, point B is selected in the general direction of the second plane toward the first mounting surface 1, the angle between the straight line P2B and the Y axis is β, and then the angle β is gradually adjusted until the plane P2AB is perpendicular to the second mounting surface 2.

[0059] Step S5 includes: step S5-1, designing the first busbar digital module 4 according to point P1, point A and point B, and designing the second busbar digital module 5 according to point P2, point B and point A; step S5-2, connecting the first busbar digital module 4 and the second busbar digital module 5 to form a twisted busbar digital module 3, and there is a twist angle θ between the first busbar digital module 4 and the second busbar digital module 5. By dividing the twisted busbar digital module 3 into the first busbar digital module 4 and the second busbar digital module 5, the design is simplified.

[0060] Specifically, the first busbar digital module 4 includes a first connection part and a first extension part, and the second busbar digital module 5 includes a second connection part and a second extension part. The first connection part is connected to the first mounting surface 1 and the center of the mounting hole of the first connection part coincides with point O1. The second connection part is connected to the second mounting surface 2 and the center of the mounting hole of the second connection part coincides with point O2. The first extension part and the second extension part are connected at one end facing each other and twisted, and the twisting angle is θ. By connecting the first extension part and the second extension part, the structure makes the design of the twisted busbar digital module 3 more accurate and simpler.

[0061] Optionally, the first extension portion and the second extension portion are equal in length. Figure 5 In the figure, the first extension portion and the second extension portion have a cross-over portion for the convenience of marking the twisting angle θ.

[0062] The step S6 includes: step S6-1, calculating the unfolded blanking length of the twisted busbar, setting the length of the first connection part to f3, the length of the second connection part to f4, the sum of the lengths of the first extension part and the second extension part to g, the number of bend buckles between the first connection part and the first extension part to e1, the number of bend buckles between the second connection part and the second extension part to e2, the number of twisted and increased materials between the first extension part and the second extension part to e3, and the unfolded blanking length L of the twisted busbar = f3 + f4 + g - e1 - e2 + e3; step S6-2, blanking and processing the twisted busbar according to the unfolded blanking length L. It can be understood that the first connection part and the first extension part and the second connection part and the second extension part will lengthen the overall length when bending, so the elongated e1 and e2 need to be deducted when blanking; and the overall length will be shortened when twisting, so the shortened twisted and increased materials e3 need to be added when blanking.

[0063] It needs to be explained that Figure 6-Figure 7As shown, the first connection part and the first extension part, as well as the second connection part and the second extension part are conventionally bent, and the bending angle between the first connection part and the first extension part is γ1, that is, γ1 is the angle between the straight line P1A and the straight line AB, γ1 is a known value, and when the thickness of the twisted busbar is a known value K, when the bending angle is γ1, the number of deductions e1 can be calculated, that is, when the thickness and the bending angle are both known, the number of deductions e1 is a known value. Similarly, when the bending angle between the second connection part and the second extension part is γ2, the number of deductions e2 can be calculated. The calculation of the number of deductions e1 and e2 is prior art.

[0064] The calculation method of the twisting material increase number e3 is as follows: the first extension part and the second extension part are connected to each other and are divided into AC segment, CD segment and DB segment. The AC segment and DB segment are clamping areas for the twisting equipment to clamp, and the CD segment is the twisting area. The length of the CD segment is set to h. When the twisting area is twisted, the length h is a fixed value and a known value. According to the parameters and process requirements of the twisting equipment, the h value can be determined. When the twisting area is h and the twisting angle is θ, the twisting material increase number e3 can be calculated.

[0065] Furthermore, the lengths of the AC segment and the DB segment are g1 and g2 respectively, and the lengths of g1 and g2 must both meet the clamping requirements of the twisting and bending equipment, and g1+g2+h=g.

[0066] For example, the twisting increase number e3 can be obtained by an experimental method, by selecting a section of material to be processed with a thickness of C and a width of W, cutting a length of the material to be processed as X1, setting the length of the twisting area to h, and twisting the material to be processed with a length of X1, and the twisting angle is θ, and measuring the length of the deformed material to be processed as X2. When the length of the twisting area is h and the twisting angle is θ, the twisting increase number e3=X1-X2.

[0067] In order to quickly obtain the twisting material increase number e3, the twisting material increase number e3 of the twisted busbars with different thicknesses, different widths and different twisting angles can be obtained through experimental methods, and a query table can be made.

[0068] Specifically, the length f3 is calculated as follows: the distance between the known point P1 and point A is f1, which is a known value, and the length f3=f1+z, where z is a given value, that is, the specific value of z can be directly given without affecting the connection between the first connecting portion and the first mounting surface 1. The length f4 is calculated as follows: the distance between the known point P2 and point B is f2, and the length f4=f2+z.

[0069] Optionally, refer to Figure 5, a through hole is provided at each of the mounting hole positions of the first connection part and the mounting hole positions of the second connection part. When the first connection part is connected to the first mounting surface 1, the center of a through hole of the first connection part coincides with point O1, a threaded hole can be provided at point O1 of the first mounting surface 1, the center of the threaded hole of the first mounting surface 1 coincides with the center of the through hole of the first connection part, a screw can be passed through the through hole of the first connection part and screwed into the threaded hole of the first mounting surface 1. When the second connection part is connected to the second mounting surface 2, the center of a through hole of the second connection part coincides with point O2, a threaded hole can be provided at point O2 of the second mounting surface 2, the center of the threaded hole of the second mounting surface 2 coincides with the center of the through hole of the first connection part, a screw can be passed through the through hole of the first connection part and screwed into the threaded hole of the second mounting surface 2.

[0070] Alternatively, if Figure 8 As shown, the mounting hole position of the first connecting part and the mounting hole position of the second connecting part are both provided with multiple through holes. When the first connecting part is connected to the first mounting surface 1, the center of the area formed by the multiple through holes of the first connecting part coincides with point O1, and threaded holes corresponding to the multiple through holes of the first connecting part can be arranged around point O1 on the first mounting surface 1, and multiple screws are respectively penetrated through the multiple through holes of the first connecting part and screwed into the multiple threaded holes of the first mounting surface 1; when the second connecting part is connected to the second mounting surface 2, the center of the area formed by the multiple through holes of the second connecting part coincides with point O2, and threaded holes corresponding to the multiple through holes of the second connecting part can be arranged around point O2 on the second mounting surface 2, and multiple screws are respectively penetrated through the multiple through holes of the second connecting part and screwed into the multiple threaded holes of the second mounting surface 2.

[0071] Optionally, refer to Figure 2 In step S2, the distance between the first plane and the first mounting surface 1 is half the thickness of the twisted busbar, and the distance between the second plane and the second mounting surface 2 is half the thickness of the twisted busbar, that is, 0.5K. This design makes the connection line P1ABP2 the center line of the twisted busbar, which makes the design simpler.

[0072] Optionally, refer to Figure 8 When multiple twist busbars need to be superimposed, and there is a gap between any two adjacent twist busbars among the multiple twist busbars, the thickness of each twist busbar is set to K, and the gap between any two adjacent twist busbars is m. For example, when n twist busbars are needed, the design process is: first, a total twist busbar is designed, and the thickness of the total twist busbar is Q=n*K+(n-1)*m; then, the total twist busbar is cut to divide it into n twist busbars with a thickness of K.

[0073] The embodiment of the present invention further provides a twisted busbar, which is manufactured by adopting the design and manufacturing method of the twisted busbar.
