[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.

[0028] The following is combined with Figures 1 to 10 The present invention provides a detailed description of a control integrated component 100, comprising: a housing 110, a main circuit board assembly, and a stator module. There are at least two stator modules, and each stator module includes a stator assembly and a connector.

[0029] In one possible implementation, at least two stator modules are defined, including a first stator module P1 and a second stator module P2. The first stator module P1 includes a first stator assembly 130 and a first connector 160, and the second stator module P2 includes a second stator assembly 140 and a second connector 170. A first reference plane A1 is defined, which passes through the axial direction of the first stator assembly 130 and the axial direction of the second stator assembly 140. At least a portion of the first connector 160 is located on one side of the first reference plane A1, and at least a portion of the second connector 170 is located on the other side of the first reference plane A1.

[0030] For ease of understanding, such as Figures 7 to 10 As shown, most of the first connector 160 is located on one side of the first reference plane A1, and most of the second connector 170 is located on the other side of the first reference plane. The first connector 160 and the second connector 170 are staggered so that the first stator assembly 130 and the second stator assembly 140 can be closer together.

[0031] In one possible implementation, the first stator assembly 130 includes a first wall portion 131 adjacent to the second stator assembly 140, the second stator assembly 140 includes a second wall portion 141 adjacent to the first stator assembly 130, at least a portion of the first connector 160 is located on the side of the first stator assembly 130 adjacent to the first wall portion 131, and at least a portion of the second connector 170 is located on the side of the second stator assembly 140 adjacent to the second wall portion 141.

[0032] For ease of understanding, such as Figure 2 and Figure 3 As shown, the axial direction of the first stator assembly 130 is substantially parallel to the axial direction of the second stator assembly 140. The outer peripheral wall of the first stator assembly 130 is close to the outer peripheral wall of the second stator assembly 140. The first wall portion 131 is a part of the outer peripheral wall of the first stator assembly 130 that is close to the outer peripheral wall of the second stator assembly 140, and the first wall portion 131 passes through the first reference plane A1. The second wall portion 141 is a part of the outer peripheral wall of the second stator assembly 140 that is close to the outer peripheral wall of the first stator assembly 130, and the second wall portion 141 passes through the first reference plane A1. The first connector 160 is not located between the first wall portion 131 and the second wall portion 141, and the second connector 170 is also not located between the first wall portion 131 and the second wall portion 141. The first connector 160 and the second connector 170 do not obstruct the approach of the first stator assembly 130 and the second stator assembly 140, which is beneficial for the first stator assembly 130 to be closer to the second stator assembly 140. A portion of the first connector 160 is located on one side of the first stator assembly 130, close to the first wall portion 131, making the structure of the first connector 160, the first stator assembly 130, and the second stator assembly 140 more compact. Furthermore, the first connector 160 can utilize the space surrounding the first wall portion 131 and the second wall portion 141. A portion of the second connector 170 is located on one side of the second stator assembly 140, close to the second wall portion 141, making the structure of the second connector 170, the first stator assembly 130, and the second stator assembly 140 more compact. Furthermore, the second connector 170 can also utilize the space surrounding the first wall portion 131 and the second wall portion 141.

[0033] In one possible implementation, a Cartesian coordinate system is defined, including an X-axis and a Y-axis. The X-axis is perpendicular to the Y-axis and the axial direction of the stator assembly. The first reference plane A1 is perpendicular to the plane passing through the X-axis and Y-axis. The X-axis and Y-axis are inclined relative to the first reference plane A1. Along the Y-axis, at least a portion of the second stator assembly 140 is located on one side of the first stator assembly 130. At least a portion of the first stator assembly 130 and the first connector 160 overlap, and at least a portion of the second stator assembly 140 and the second connector 170 overlap. Along the X-axis, at least a portion of the first stator assembly 130 and the second connector 170 overlap, and at least a portion of the second stator assembly 140 and the first connector 160 overlap.

[0034] For ease of understanding, such as Figures 3 to 10As shown, along the Y-axis, a portion of the second stator assembly 140 is located on one side of the first stator assembly 130, a portion of the first stator assembly 130 and the first connector 160 overlap, and a portion of the second stator assembly 140 and the second connector 170 overlap; along the X-axis, a portion of the first stator assembly 130 and the second connector 170 overlap, and a portion of the second stator assembly 140 and the first connector 160 overlap; thus, the structure of the first stator assembly 130, the second stator assembly 140, the first connector 160 and the second connector 170 is more compact, which helps to reduce the size of the control integrated component 100.

[0035] In one possible implementation, the stator assembly is generally cylindrical in shape, there are at least two stator assemblies, the at least two stator assemblies are arranged axially parallel, there are at least two connectors, the at least two stator assemblies are electrically connected to the at least two connectors, and the at least two connectors are electrically connected to the main circuit board assembly 120.

[0036] In one possible implementation, the Cartesian coordinate system further includes a Z-axis direction, which is perpendicular to the X-axis direction and the Y-axis direction. Along the Z-axis direction, at least a portion of the first stator assembly 130 and the second stator assembly 140 are overlapped, and at least a portion of the first connector 160 and the second connector 170 are overlapped.

[0037] In one possible implementation, the connector includes a plug portion, a flexible portion, and a sub-circuit board assembly. The plug portion is located on one side of the flexible portion, and the sub-circuit board assembly is located on the other side of the flexible portion. The plug portion is limited and electrically connected to the main circuit board assembly 120, and the sub-circuit board assembly is limited and electrically connected to the corresponding stator assembly.

[0038] Further, the first connector 160 is defined as including a first insertion portion 161, a first flexible portion 162, and a first sub-circuit board assembly 163. The first insertion portion 161 is located on one side of the first flexible portion 162, and the first sub-circuit board assembly 163 is located on the other side of the first flexible portion 162. The first insertion portion 161 is positioned and electrically connected to the main circuit board assembly 120, and the first sub-circuit board assembly 163 is positioned and electrically connected to the first stator assembly 130. The second connector 170 includes a second insertion portion 171, a second flexible portion 172, and a second sub-circuit board assembly 173. The second insertion portion 171 is located on one side of the second flexible portion 172, and the second sub-circuit board assembly 173 is located on the other side of the second flexible portion 172. The second insertion portion 171 is positioned and electrically connected to the main circuit board assembly 120, and the second sub-circuit board assembly 173 is positioned and electrically connected to the second stator assembly 140.

[0039] For ease of understanding, such as Figure 3 and Figure 4As shown, the first connector 161 is a pin header. Part of the first connector 161 is located in the metal via of the main circuit board assembly 120, and the first connector 161 abuts against and forms the inner wall of the metal via of the main circuit board assembly 120, thereby facilitating electrical conduction between the first connector 161 and the main circuit board assembly 120. The first flexible part 162 is a flexible flat cable, abbreviated as FFC. One side of the first flexible part 162 is located in the first connector 161, and the other side of the first flexible part 162 is located in the first sub-circuit board assembly 163. The flexible part can be bent or folded. Considering that the structure of the control integrated component 100 is relatively compact, the flexible part that can be bent or folded facilitates the placement of the first connector 161 and the first sub-circuit board assembly 163 in a small space, and also facilitates the assembly of the first connector 161 and the first sub-circuit board assembly 163 into the main circuit board assembly 120 and the first stator assembly 130. The winding wires of the first stator assembly 130 are wound around the pins of the first stator assembly 130. Some of the pins of the first stator assembly 130 are located in the metal vias of the first sub-circuit board assembly 163. Furthermore, the pins of the first stator assembly 130 and the first sub-circuit board assembly 163 are fixed by soldering, which facilitates electrical conduction between the pins of the first stator assembly 130 and the first sub-circuit board assembly 163.

[0040] The structures of the other connectors and stator assemblies are the same as those of the first connector 160 and the first stator assembly 130, and will not be described in detail here.

[0041] In one possible implementation, at least a portion of the sub-circuit board assembly is located on one axial side of the corresponding stator assembly, and along the Y-axis direction, at least a portion of one sub-circuit board assembly is located on one side of another sub-circuit board assembly; along the X-axis direction, at least a portion of the two sub-circuit board assemblies are arranged overlappingly.

[0042] Furthermore, at least a portion of the first sub-circuit board assembly 163 is located on one axial side of the first stator assembly 130, and at least a portion of the second sub-circuit board assembly 173 is located on one axial side of the second stator assembly 140 near the first sub-circuit board assembly 163; along the Y-axis direction, at least a portion of the second sub-circuit board assembly 173 is located on one side of the first sub-circuit board assembly 163; along the X-axis direction, at least a portion of the first sub-circuit board assembly 163 and the second sub-circuit board assembly 173 are overlapped.

[0043] For ease of understanding, such as Figure 2As shown, the first sub-circuit board assembly 163 is substantially located on one axial side of the first stator assembly 130, and the second sub-circuit board assembly 173 is substantially located on one axial side of the second stator assembly 140. The first sub-circuit board assembly 163 and the second sub-circuit board assembly 173 are arranged close to each other. Along the Y-axis direction, a portion of the second sub-circuit board assembly 173 is located on one side of the first sub-circuit board assembly 163; along the X-axis direction, a portion of the second sub-circuit board assembly 173 and the first sub-circuit board assembly 163 are overlapped. In this way, the structure of the first sub-circuit board assembly 163 and the second sub-circuit board assembly 173 is more compact, which is more conducive to reducing the size of the control integrated component 100.

[0044] In one possible implementation, the sub-circuit board assembly includes a sub-substrate, a flexible portion is positioned and electrically connected to the sub-substrate, and the sub-substrate is positioned and electrically connected to a corresponding stator assembly.

[0045] In one possible implementation, the sub-circuit board assembly includes a Hall sensor that is positioned and electrically connected to the sub-substrate; the stator assembly has a cavity, and the Hall sensor is located on the side of the sub-substrate closer to the cavity.

[0046] Furthermore, the first sub-circuit board assembly 163 is defined to include a first sub-substrate 1631 and a first Hall sensor 1632. The first Hall sensor 1632 and the first flexible part 162 are phase-fitted and electrically connected to the first sub-substrate 1631. The first stator assembly 130 is defined to have a first cavity 132. The first Hall sensor 1632 is located on the side of the first sub-substrate 1631 near the first cavity 132.

[0047] For ease of understanding, such as Figure 4 As shown, the first sub-substrate 1631 and the first Hall sensor 1632 are basically located on one side of the axial direction of the first stator assembly 130. The first Hall sensor 1632 is located on one side of the first sub-substrate 1631 and is close to the first cavity 132. The first cavity 132 can accommodate the rotor assembly. In this way, the first Hall sensor 1632 can be closer to the rotor assembly, which is beneficial for the first Hall sensor 1632 to detect the movement of the rotor assembly.

[0048] In one possible implementation, at least some of the sub-circuit board assemblies are located radially outside the corresponding stator assembly, and no two sub-circuit board assemblies are arranged adjacent to each other.

[0049] Furthermore, at least a portion of the first sub-circuit board assembly 163 is located radially outside the first stator assembly 130, and at least a portion of the second sub-circuit board assembly 173 is located radially outside the second stator assembly 140. The first sub-circuit board assembly 163 is located near the first wall portion 131 on the side away from the second sub-circuit board assembly 173, and the second sub-circuit board assembly 173 is located near the second wall portion 141 on the side away from the first sub-circuit board assembly 163. Along the Y-axis direction, at least a portion of the second stator assembly 140 is located on one side of the first sub-circuit board assembly 163, and at least a portion of the second sub-circuit board assembly 173 is located on one side of the first stator assembly 130.

[0050] For ease of understanding, such as Figure 6 As shown, the first sub-circuit board assembly 163 is located approximately radially outside the first stator assembly 130, and the second sub-circuit board assembly 173 is located approximately radially outside the second stator assembly 140. The first sub-circuit board assembly 163 is located on one side of the first reference plane A1, and the second sub-circuit board assembly 173 is located on the other side of the first reference plane A1, so that the two stator assemblies can be closer together. The first sub-circuit board assembly 163 is located on the side near the first wall portion 131, and the second sub-circuit board assembly 173 is located on the other side of the first wall portion 131. The first sub-circuit board assembly 163 is located on the side of the first wall portion 131 away from the second sub-circuit board assembly 173, and the first sub-circuit board assembly 163 is located away from the first wall portion 131 relative to the second sub-circuit board assembly 173. The second sub-circuit board assembly 173 is located on the side near the second wall portion 141, and the second sub-circuit board assembly 173 is located on the other side of the second wall portion 141. The second sub-circuit board assembly 173 is located on the side of the second wall portion 141 away from the first sub-circuit board assembly 163, and the second sub-circuit board assembly 173 is located away from the first wall portion 131 relative to the first sub-circuit board assembly 163. In this way, the first sub-circuit board assembly 163 and the second sub-circuit board assembly 173 are staggered and arranged in the space around the first wall portion 131 and the second wall portion 141. Along the Y-axis, a portion of the second stator assembly 140 is located on one side of the first sub-circuit board assembly 163, and the second sub-circuit board assembly 173 is located on one side of the first stator assembly 130, making the structure of the first sub-circuit board assembly 163, the second sub-circuit board assembly 173, the first stator assembly 130, and the second stator assembly 140 more compact.

[0051] In one possible implementation, the sub-circuit board assembly includes a stator drive module, which is positioned and electrically connected to the sub-substrate.

[0052] Furthermore, the first sub-circuit board assembly 163 is defined to include a first stator drive module 1633, which is located radially outside the first stator assembly 130.

[0053] For ease of understanding, such asFigure 6 As shown, the first stator drive module 1633 includes, but is not limited to, a bridge drive circuit. Under the control of the main circuit board assembly 120, the first stator drive module 1633 can generate drive signals to drive the first stator assembly 130 to work. The first stator drive module 1633 is located radially outside the first stator assembly 130. Along the X-axis, the first stator drive module 1633 and the first stator assembly 130 are arranged sequentially, with a portion of the first stator drive module 1633 overlapping with the second stator assembly 140. This makes the structure of the first sub-circuit board assembly 163, the first stator assembly 130, and the second stator assembly 140 more compact. Compared with related technologies, the first sub-circuit board assembly 163 adds functions such as drive control. The first sub-circuit board assembly 163 shares some of the original functions of the main circuit board assembly 120, allowing the size of the first sub-circuit board assembly 163 to be increased and the size of the main circuit board assembly 120 to be decreased. The size of the first sub-circuit board assembly 163 and the size of the main circuit board assembly 120 become more reasonable, which is conducive to a more compact structure of the sub-circuit board assembly, the main circuit board assembly 120, and the stator assembly.

[0054] In one possible implementation, the main circuit board assembly 120 and at least two stator modules are located within the housing 110.

[0055] Furthermore, the first stator assembly 130, the second stator assembly 140, the first connector 160, the second connector 170, and the main circuit board assembly 120 are located inside the housing 110, with the Y-axis direction aligned with the length direction of the housing 110 and the X-axis direction aligned with the width direction of the housing 110; along the length direction of the housing 110, a portion of the second stator assembly 140 and the first stator assembly 130 overlap; along the width direction of the housing 110, a portion of the second stator assembly 140 and the first stator assembly 130 overlap.

[0056] For ease of understanding, such as Figures 2 to 6 As shown, the first stator assembly 130, the second stator assembly 140, the first connector 160, the second connector 170, and the main circuit board assembly 120 are all located inside the housing 110, which provides a sealed protection for these components.

[0057] Figure 3 and Figure 5 In the first stator assembly 130 and the second stator assembly 140, the arrangement direction is inclined relative to the X-axis direction or the Y-axis direction. The arrangement direction of the first connector 160 and the second connector 170 is also inclined relative to the X-axis direction or the Y-axis direction. The two arrangement directions are staggered, which helps to improve the compactness of the structure.

[0058] In one possible implementation, the sidewalls of the housing 110 are defined as a third sidewall 1111, a fourth sidewall 1112, a first sidewall 1113, and a second sidewall 1114. Along the length of the housing 110, the third sidewall 1111 and the fourth sidewall 1112 are arranged sequentially. The second stator assembly 140 is closer to the third sidewall 1111 than the first stator assembly 130, and the first stator assembly 130 is closer to the fourth sidewall 1112 than the second stator assembly 140. In the width direction of 110, the first sidewall 1113 and the second sidewall 1114 are arranged in sequence. The second stator assembly 140 is closer to the first sidewall 1113 than the first stator assembly 130, and the first stator assembly 130 is closer to the second sidewall 1114 than the second stator assembly 140. The first stator assembly 130 and the second stator assembly 140 are offset to the front and rear sides of the housing 110, and the first stator assembly 130 and the second stator assembly 140 are also offset to the left and right sides of the housing 110. The first connector 160 is closer to the second side wall 1114 relative to the second connector 170, and the second connector 170 is closer to the first side wall 1113 relative to the first connector 160. The first connector 160 and the second connector 170 are also offset towards the front and rear sides of the housing 110, and the first connector 160 and the second connector 170 are offset towards the left and right sides of the housing 110, making the first stator assembly 130, the second stator assembly 140, the first connector 160 and the second connector 170 more compact. This helps to reduce the length and width of the housing 110, and further helps to reduce the size of the control integrated component 100.

[0059] In one possible implementation, the Z-axis direction is consistent with the height direction of the housing 110. Along the height direction of the housing 110, the first stator assembly 130 and the second stator assembly 140 are set at the same height, and the first connector 160 and the second connector 170 are set at the same height.

[0060] For ease of understanding, such as Figure 2 As shown, the axial direction of the stator assembly is basically consistent with the height direction of the housing 110, and at least two stator assemblies are set at approximately the same height, which helps to reduce the height of the housing 110.

[0061] In one possible implementation, the housing 110 includes a reinforcing portion located within the housing 110, and there are at least two reinforcing portions, with at least two reinforcing portions and at least two stator assemblies correspondingly arranged.

[0062] Furthermore, the at least two reinforcing portions are defined as a first reinforcing portion 112 and a second reinforcing portion 113. Along the length direction of the housing 110, at least a portion of the first reinforcing portion 112 is located on one side of the second stator assembly 140, and at least a portion of the second reinforcing portion 113 is located on one side of the first stator assembly 130. Along the width direction of the housing 110, at least a portion of the first reinforcing portion 112 is located on the side of the first stator assembly 130 near the first connector 160, and at least a portion of the second reinforcing portion 113 is located on the side of the second stator assembly 140 near the second connector 170.

[0063] For ease of understanding, such as Figure 3 and Figure 5 As shown, a first reinforcing portion 112 is formed on the second sidewall 1114, and a second reinforcing portion 113 is formed on the first sidewall 1113. The arrangement of the reinforcing portions helps to improve the structural strength of the housing 110. The first reinforcing portion 112 is located radially outward of the first stator assembly 130 and also radially outward of the second stator assembly 140. The first reinforcing portion 112 and the first connector 160 are disposed adjacent to each other. The first reinforcing portion 112 can abut against and cooperate with the outer peripheral walls of the first stator assembly 130 and the second stator assembly 140. The reinforcing portions and stator assemblies are compactly arranged, which further helps to reduce the size of the control integration component 100 and the structural strength of the housing 110.

[0064] In one possible implementation, the housing 110 includes a partition, the partition and the reinforcement are integral structures, the partition is at least one, and at least one partition separates at least two stator assemblies.

[0065] Furthermore, the partition defined at least includes a first partition 115, a first reinforcing part 112 located on one side of the first partition 115, and a second reinforcing part 113 located on the other side of the first partition 115. The first partition 115 separates the first stator assembly 130 and the second stator assembly 140. One side of the first partition 115 is close to the second sidewall 1114 relative to the first stator assembly, and the other side of the first partition 115 is close to the first sidewall 1113 relative to the second stator assembly.

[0066] For ease of understanding, such as Figure 3 and Figure 5As shown, the first partition 115 has a plate-like overall structure. The first partition 115 extends from the first reinforcing part 112 to the second reinforcing part 113. The arrangement of the first partition 115 further enhances the structural strength of the housing 110. The extension direction of the first partition 115 is inclined relative to the length direction and the width direction of the housing 110. The first partition 115 separates the first stator assembly 130 and the second stator assembly 140. A portion of the first partition 115 is located between the first stator assembly 130 and the second stator assembly 140. The first wall portion 131 is approximately located on one side of the first partition 115, and the second wall portion 141 is located on the other side of the first partition 115, thus separating the first stator assembly 130 and the second stator assembly 140 within the housing 110. The partition also includes a second partition 116, a second reinforcing part 113 located on one side of the second partition 116, and a third reinforcing part 114 located on the other side of the second partition 116. The second partition 116 separates the second stator assembly 140 and the third stator assembly 150.

[0067] In one possible implementation, the first partition 115 divides the interior of the housing 110 into a first receiving cavity 117 and a second receiving cavity 118, with at least a portion of the first stator assembly 130 located in the first receiving cavity 117 and at least a portion of the second stator assembly 140 located in the second receiving cavity 118. The first receiving cavity 117 is closer to the first sidewall 1113 relative to the second receiving cavity 118, and the second receiving cavity 118 is closer to the second sidewall 1114 relative to the first receiving cavity 117.

[0068] In one possible implementation, the reinforcement includes a guide rail located on the side of the reinforcement close to the main circuit board assembly 120, and the connector slides on the guide rail. At least a portion of the main circuit board assembly 120 is located in the sliding path of the connector relative to the guide rail.

[0069] Furthermore, at least one guide rail portion is defined, including a first guide rail portion 1122, which is located on the side of the first reinforcing portion 112 near the main circuit board assembly 120. The first connector 160 is slidably engaged with the first guide rail portion 1122, and at least a portion of the main circuit board assembly 120 is located in the sliding path of the first connector 160 relative to the first guide rail portion 1122.

[0070] For ease of understanding, such as Figure 3As shown, the guide rail, reinforcing part, and partition are an integral structure. There are two first guide rails 1122, which are located on the upper side of the first reinforcing part 112. The first connector 161 is slidably engaged with the two first guide rails 1122. When the first connector 161 slides relative to the two first guide rails 1122, the first connector 161 can slide along the height direction of the housing 110. A portion of the main circuit board assembly 120 is located on the axial upper side of the stator assembly. By sliding the first connector 161, the first connector 161 and the main circuit board assembly 120 can be conveniently engaged.

[0071] In one possible implementation, the first reinforcing part 112 includes a first rib 1121, and there are at least two first ribs 1121 arranged along the length direction of the housing 110, with the at least two first ribs 1121 spaced apart.

[0072] For ease of understanding, such as Figure 4 As shown, the gap between the two first ribs 1121 extends along the height direction of the housing 110, and the cavity is beneficial to the weight reduction of the first reinforcing part 112.

[0073] In one possible implementation, there are at least three stator modules.

[0074] Further, the third stator module is defined as the third stator module P3. The third stator module P3 includes a third stator assembly 150 and a third connector 180. The third stator assembly 150 is electrically connected to the third connector 180, and the third connector 180 is electrically connected to the main circuit board assembly 120. A second reference plane A2 is defined. The second reference plane A2 is perpendicular to the plane passing through the X-axis and Y-axis directions. The second reference plane A2 is inclined relative to the X-axis direction, the second reference plane A2 is inclined relative to the Y-axis direction, and the second reference plane A2 is inclined relative to the first reference plane A1. At least a portion of the second connector 170 is located on one side of the second reference plane A2, and at least a portion of the third connector 180 is located on the other side of the second reference plane A2. Along the Y-axis direction, at least a portion of the third stator assembly 150 is located on one side of the first stator assembly 130, and at least a portion of the third stator assembly 150 and the first stator assembly 130 overlap. Along the X-axis direction, at least a portion of the third stator assembly 150 and the second stator assembly 140 overlap. The third stator assembly 150 and the second stator assembly 140 are disposed adjacent to each other; the second stator assembly 140 includes a third wall portion 142 near the third stator assembly 150, the third stator assembly 150 includes a fourth wall portion 151 near the third stator assembly 150, at least a portion of the second connector 170 is located on the side of the second stator assembly 140 near the third wall portion 142, and at least a portion of the third connector 180 is located on the side of the third stator assembly 150 near the fourth wall portion 151; along the Y-axis direction, a portion of the third stator assembly 150 is located on one side of the second stator assembly 140, a portion of the first stator assembly 130 is located on the other side of the second stator assembly 140, and at least a portion of the third stator assembly 150 and the third connector 180 are disposed overlappingly; along the X-axis direction, at least a portion of the third stator assembly 150 and the second connector 170 are disposed overlappingly, at least a portion of the second stator assembly 140 and the third stator assembly 150 are disposed overlappingly, and at least a portion of the third connector 180 and the first connector 160 are disposed overlappingly.

[0075] For ease of understanding, such as Figure 3 and Figure 5As shown, the first stator assembly 130 and the third stator assembly 150 are located on both sides of the second stator assembly 140, and the third stator assembly 150 and the second stator assembly 140 are also arranged adjacent to each other. The arrangement direction of the first stator assembly 130, the second stator assembly 140 and the third stator assembly 150 is roughly "V" shaped. Along the length direction of the housing 110, the third stator assembly 150 and the first stator assembly 130 are arranged sequentially, and the third connector 180 and the first connector 160 are arranged sequentially. Along the width direction of the housing 110, part of the third stator assembly 150 and the second connector 170 overlap, part of the second stator assembly 140 and the third connector 180 overlap, and the third connector 180 and the first connector 160 overlap. The arrangement direction of the three stator assemblies and the arrangement direction of the three connectors are intersected, making the structure of the three stator assemblies and the three connectors more compact. This is beneficial to reducing the size of the control integrated component 100 with more than three stator assemblies. The reinforcement also includes a third reinforcement 114, which is positioned corresponding to the third stator assembly 150.

[0076] In one possible implementation, there are eight stator modules, each including a stator assembly and connectors. The eight connectors and eight stator assemblies are arranged correspondingly, and the arrangement of the eight stator assemblies is roughly in a zigzag shape, as is the arrangement of the eight connectors. There are eight reinforcing sections and seven dividing sections, with the seven dividing sections positioned between each pair of the eight reinforcing sections. The arrangement of the eight reinforcing sections and the seven dividing sections is roughly in a zigzag shape. The arrangement directions of the eight stator assemblies, the eight connectors, and the eight reinforcing sections and the seven dividing sections are interleaved, which helps to reduce the size of the control integrated component 100 with eight stator assemblies.

[0077] In one possible implementation, at least a portion of the main circuit board assembly 120 is located on one axial side of the stator assembly.

[0078] Furthermore, along the Y-axis direction, at least a portion of the main circuit board assembly 120, the first connector 160, and the first stator assembly 130 are arranged in an overlapping manner, and at least a portion of the main circuit board assembly 120, the second connector 170, and the second stator assembly 140 are arranged in an overlapping manner.

[0079] For ease of understanding, such as Figure 2 As shown, the main circuit board assembly 120 is generally located above the stator assembly, and the sub-circuit board assembly can be located above the stator assembly. Along the length of the housing 110, parts of the main circuit board assembly 120, the sub-circuit board assembly and the corresponding stator assembly are overlapped, making the structure of the main circuit board assembly 120, the sub-circuit board assembly and the stator assembly more compact, which helps to reduce the size of the housing 110.

[0080] In one possible implementation, the main circuit board assembly 120 includes a component area 121, with a first connector 161 located on one side of the component area 121 and a second connector 171 located on the other side of the component area 121 away from the first connector 161. This is beneficial to improving the board surface utilization of the main circuit board assembly 120.

[0081] This embodiment also provides a thermal management system, including the control integration component 100 described above, and also including a valve component. The valve component includes a rotor assembly, a valve core assembly, and a valve body.

[0082] There are at least two rotor assemblies, with at least two rotor assemblies corresponding to at least two stator assemblies. The rotor and stator assemblies can constitute either a stepper motor or a brushless DC motor. The at least two stator assemblies can control the movement of the at least two rotor assemblies. There are also at least two valve core assemblies, with at least two valve core assemblies corresponding to at least two rotor assemblies. The valve core assemblies are positioned and fitted with the corresponding rotor assemblies. At least two rotor assemblies are rotatably fitted onto the valve body, and at least two valve core assemblies are positioned and fitted with the valve body housing. At least a portion of the rotor assemblies are located within the cavity of the stator assembly, and at least a portion of the valve core assemblies are located within the flow channel of the valve body. Refrigerant can flow through the flow channel. The movement of the rotor assemblies allows the valve core assemblies to regulate the refrigerant flow rate and pressure.
