[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] See also Figure 1-Figure 4 An embodiment of the utility model provides a bus structure 10 and a motor 100, wherein the motor 100 includes a stator structure 20 and the bus structure 10, wherein the bus structure 10 connects the multi-phase lead wires of the stator structure 20 in parallel, thereby arranging the complex multi-phase lead wires on the stator structure 20, and realizing electrical transmission between the control system and the stator structure 20 through the bus structure 10.

[0032] The busbar structure 10 includes a fixing member 11, a vertical plate assembly 12 and a multi-phase busbar 13; the fixing member 11 is arranged in an arc shape; the vertical plate assembly 12 is arranged upright on the outer arc side of the fixing member 11; the multi-phase busbar 13 has a plurality of busbars, each of which includes a busbar body 131 and a connecting portion 132 and a lead-out portion 133 connected to both ends of the busbar body 131, the connecting portion 132 is used to electrically connect to the lead-out pins of the stator, and the lead-out portion 133 is used to electrically connect to an external power supply device. The busbar body 131 is arranged in an arc shape, and the arc extension direction of the busbar body 131 is the same as the arc extension direction of the fixing member 11, and the plurality of busbar bodies 131 are arranged in sequence along the height extension direction of the vertical plate assembly 12 and are arranged through the vertical plate assembly 12; the plurality of connecting portions 132 are arranged on the fixing member 11 at intervals along the arc extension direction of the fixing member 11.

[0033] In the present invention, when the busbar structure 10 is assembled with the stator structure 20, the arc-shaped fixing member 11 is adapted to be located at the end side of the stator structure 20, so that the multiple connecting parts 132 arranged on the fixing member 11 can be electrically connected to the multiple lead pins on the stator structure 20 in a one-to-one correspondence; the lead-out part 133 of the busbar is electrically connected to the external power supply device, thereby realizing the electrical connection between the busbar and the stator structure 20; wherein each busbar is connected between the connecting part 132 and the lead-out part 133 The busbar bodies 131 are all arranged through the vertical plate assembly 12, and the multiple busbar bodies 131 are arranged in sequence along the height extension direction of the vertical plate assembly 12. The multiple busbar bodies 131 are regularized by the vertical plate assembly 12 and concentrated on the vertical plate assembly 12, which improves the correlation between the busbar bodies 131 in terms of positional relationship, thereby improving the integration of the busbar structure 10 and the overall stability of the busbar structure 10, and solving the technical problem of low overall stability of the busbar structure 10 in the prior art.

[0034] It should be noted that when the busbar structure 10 is assembled with the stator, the vertical plate members are vertically arranged on the peripheral side of the stator structure 20. On the one hand, the vertical plate members arranged vertically reduce the increase or decrease of the space required for the busbar structure 10 in the transverse direction; on the other hand, in the longitudinal direction, the vertical plate members at least partially overlap with the stator structure 20, thereby reducing the increase of the space required for the vertical plate assembly 12 in the longitudinal direction.

[0035] In some specific embodiments, see Figure 1The stator structure 20 is provided with a receiving groove 21 on its circumferential side, and the vertical plate assembly 12 is arranged in the receiving groove 21. The vertical plate assembly 12 is received and placed by the receiving groove 21, which further reduces the extra space required for the vertical plate assembly 12 in the transverse direction and the longitudinal direction, thereby avoiding the problem of the housing being enlarged to accommodate the vertical plate assembly 12.

[0036] In some specific embodiments, see Figure 4 The busbar further includes a bending portion 134 , which is connected between the busbar body 131 and the lead-out portion 133 , and extends toward the outer arc side of the busbar body 131 .

[0037] Specifically, since the vertical plate assembly 12 is arranged on the peripheral side of the stator structure 20, the busbar body 131 restricted on the vertical plate assembly 12 is also arranged along the peripheral side of the stator structure 20; by providing a bending portion 134 between the busbar body 131 and the lead-out portion 133, and the bending portion 134 extends toward the outer arc side of the busbar body 131, the lead-out portion 133 connected to the bending portion 134 can extend in a direction away from the peripheral side of the stator structure 20, so as to facilitate the electrical connection of the lead-out portion 133 with an external power supply device.

[0038] The multi-phase busbar 13 includes a first-phase busbar 13a, a second-phase busbar 13b and a third-phase busbar 13c.

[0039] In some specific embodiments, the first phase busbar 13 a , the second phase busbar 13 b , and the third phase busbar 13 c correspond to the U phase, the V phase, and the W phase, respectively.

[0040] In some specific embodiments, see Figure 2 There are at least two first-phase busbars 13a, wherein a connection portion 132 of one of the first-phase busbars 13a is located on the inner arc side of the fixing member 11, and another connection portion 132 of the first-phase busbar 13a is located on the outer arc side of the fixing member 11.

[0041] In some specific embodiments, see Figure 2 There are at least two second-phase busbars 13 b , wherein a connection portion 132 of one of the second-phase busbars 13 b is located on the inner arc side of the fixing member 11 , and another connection portion 132 of the second-phase busbar 13 b is located on the outer arc side of the fixing member 11 .

[0042] In some specific embodiments, see Figure 2There are at least two third-phase busbars 13 c , wherein a connection portion 132 of one of the third-phase busbars 13 c is located on the inner arc side of the fixing member 11 , and another connection portion 132 of the third-phase busbar 13 c is located on the outer arc side of the fixing member 11 .

[0043] In some specific embodiments, the fixing member 11 is a plastic member.

[0044] In some specific embodiments, the vertical plate assembly 12 is a plastic part.

[0045] In one embodiment, see Figure 2 and Figure 3 The vertical plate assembly 12 includes a first vertical plate 121 and a second vertical plate 122 arranged in an arranged manner, and the arrangement direction of the first vertical plate 121 and the second vertical plate 122 is the same as the arc-shaped extension direction of the fixing member 11. By arranging the first vertical plate 121 and the second vertical plate 122 arranged in an arc shape, the busbar body 131 arranged on the first vertical plate 121 and the first vertical plate 121 is also arranged in an arc shape, which not only realizes the stable fixing of the busbar body 131 by the first vertical plate 121 and the second vertical plate 122, but also makes the busbar body 131 adapt to the peripheral side arrangement of the stator structure 20.

[0046] See also Figure 2 and Figure 3 In the arc-shaped extension direction of the fixing member 11, the first vertical row of plates 121 is staggered with the fixing member 11, and the second vertical row of plates 122 overlaps with the fixing member 11; wherein the distance between the first vertical row of plates 121 and the lead-out portion 133 is greater than the distance between the second vertical row of plates 122 and the lead-out portion 133.

[0047] Specifically, the portion of the busbar body 131 that does not extend to the outer arc side of the fixing member 11 is fixed and restricted by the first vertical plate 121, and the portion of the busbar body 131 that extends to the outer arc side of the fixing member 11 is fixed and restricted by the second vertical plate 122, thereby improving the overall fixing stability of the vertical plate assembly 12 on the busbar body 131.

[0048] It should be noted that in the arc-shaped extension direction of the fixing member 11, the second vertical row of plates 122 overlaps with the fixing member 11, which means that the second vertical row of plates 122 are located in the radial extension direction of the fixing member 11; however, in the height extension direction of the second vertical row of plates 122, the second vertical row of plates 122 and the fixing member 11 can be arranged to overlap or be staggered.

[0049] In some specific embodiments, see Figure 2, the number of busbar bodies 131 passing through the second vertical plate 122 is less than the number of busbar bodies 131 passing through the first vertical plate 121. Specifically, after some busbar bodies 131 pass through the first vertical plate 121, they are connected to the corresponding connection parts 132; after some busbar bodies 131 pass through the first vertical plate 121, they pass through the second vertical plate 122 and are connected to the corresponding connection parts 132, thereby realizing the sequential arrangement of the busbar bodies 131.

[0050] In some specific embodiments, see Figure 2 There are multiple second vertical plates 122, and the number of the buses passing through the second vertical plates 122 gradually decreases in the direction away from the first vertical plates 121.

[0051] Specifically, in the direction away from the first vertical row of plates 121, each time the second vertical row of plates 122 is passed through, part of the busbar bodies 131 are connected to the corresponding connecting parts 132, so that the number of busbar bodies 131 passing through the second vertical row of plates 122 is gradually reduced, thereby realizing the successive arrangement of the busbar bodies 131 after extending to the outer arc side of the fixing member 11.

[0052] In some specific embodiments, there are two second vertical plates 122 .

[0053] In some specific embodiments, see Figure 2 and Figure 3 The fixing member 11 includes a solid shell body 111 and a plurality of protrusions 112 .

Each of the connecting portions 132 is arranged on each of the protrusions 112 in a one-to-one correspondence.

[0054] By arranging the protrusions 112 at multiple different positions of the solid shell body 111 , the multiple connection parts 132 can be arranged on each protrusion 112 in a one-to-one correspondence, so that the multiple connection parts 132 are arranged at different positions of the fixing member 11 .

[0055] In some specific embodiments, see Figure 2 , each connection portion 132 is disposed on each protrusion 112 in a penetrating manner.

[0056] In some specific embodiments, see Figure 3 The fixing member 11 is also formed with a groove 11 a, through which the glue can be reduced to prevent the fixing member 11 from shrinking.

[0057] In one embodiment, see Figure 2 and Figure 3The busbar structure 10 also includes a neutral point copper busbar 14, which includes a copper busbar body 141 and a plurality of neutral connecting pins 142.

[0058] In this embodiment, by setting the copper busbar body 141 to an arc shape in the same extension direction as the fixing member 11, the copper busbar body 141 can be adaptively embedded in the fixing member 11, thereby achieving a stable connection between the neutral point copper busbar 14 and the fixing member 11; and a neutral connection foot 142 of the neutral point copper busbar 14 is set to pass through the fixing member 11, so that the neutral connection foot 142 can be connected to the neutral point welding part on the stator structure 20.

[0059] In some specific embodiments, the copper busbar body 141 is embedded into the solid shell body 111 .

[0060] In some specific embodiments, see Figure 2 The plurality of neutral connection pins are divided into two groups, one of which is located on the outer arc side of the fixing member 11, and the other is located on the inner arc side of the fixing member 11. On the one hand, it adapts to the distribution of the neutral welding part on the stator structure 20, and facilitates the connection between the neutral connection pin and the neutral welding part; on the other hand, the inner and outer arc sides of the fixing member 11 are both provided with neutral connection pins, so that after the neutral point copper bar 14 and the stator structure 20 are welded, the fixing member 11 and the neutral point copper bar 14 are more stably arranged on the stator structure 20 as a whole.

[0061] In one embodiment, see Figure 1 and Figure 2 The bus structure 10 further includes a lead-out guide 15, and a plurality of the lead-out portions 133 are arranged through the lead-out guide 15. The lead-out guide 15 is used to regularize the plurality of lead-out portions 133 and centrally limit them to the lead-out guide 15, thereby improving the correlation between the positional relationships of the lead-out portions 133, thereby improving the integration and stability of the bus structure 10.
