Technical Field

[0001] This invention relates to the field of thermal management technology, and in particular to a thermal management device for vehicles or energy storage. Background Technology

[0002] Typically, electrical connection components include male terminals and female terminals. The male terminal includes a male pin, and the female terminal includes a female pin. The male and female terminals are plugged together to achieve electrical connection between the male pin and the female pin. When the assembly tolerance between the male and female terminals is large, assembly problems may occur. Summary of the Invention

[0003] Based on this, the present application provides an electrical connection component and a thermal management device, which facilitates increasing the floating amount of the first terminal and facilitating the electrical connection of the first terminal with other structures.

[0004] On one hand, the technical solution of this application provides an electrical connection assembly, the electrical connection assembly including a first terminal, the first terminal having a first housing, a first conductive element and a retainer, the first housing including a plug portion, the plug portion being spaced apart from the retainer, the first conductive element including a first pin and a flexible wire, at least a portion of the first pin being limited within the plug portion, the flexible wire including a first connecting segment, a second connecting segment and a deformable segment, the deformable segment being connected between the first connecting segment and the second connecting segment, the first pin being fixedly connected to and electrically connected to the first connecting segment, the second connecting segment being limited within the retainer, at least a portion of the deformable segment being supported between the plug portion and the retainer, the deformable segment being configured such that the deformable segment has a deformable capability to cause the first pin and the first housing relative to the retainer to shift or swing.

[0005] According to the electrical connection assembly provided in this application, the first terminal of the electrical connection assembly includes a flexible wire, and the first connecting segment of the flexible wire is electrically connected to the first pin. The second connecting segment of the flexible wire is limited by the retainer, which facilitates the transmission of electrical signals by the flexible wire and limits the position of the flexible wire. By setting a deformation segment on the flexible wire, and because the flexible wire is flexible, the position of the flexible wire can be easily adjusted. By setting a deformation segment, the flexible wire has deformation capability, so that during the position displacement process, the flexible wire drives the first pin and the first housing component to shift or swing relative to the retainer, which facilitates the adjustment of the position of the first pin and the first housing component. When the first terminal is used for mating connection with other structural components, the deformation of the flexible wire facilitates the assembly of the first pin and the first housing component with other structural components, which is beneficial for the first pin to compensate for assembly tolerances during the assembly process.

[0006] On the other hand, the present application provides a thermal management device including the above-mentioned electrical connection components. The thermal management device includes a control component, a drive component, and a fluid component. The control component includes a first terminal and a circuit board. The drive component includes a second terminal and a motor. The first terminal includes a first conductive element, and the second terminal includes a second conductive element. The motor is electrically connected to the second conductive element, and the second conductive element is electrically connected to the circuit board through the first conductive element. The motor can drive the fluid component to operate.

[0007] According to the thermal management device provided in this application, the first terminal of the electrical connection assembly includes a flexible wire, and the first connecting segment of the flexible wire is electrically connected to the first pin. The second connecting segment of the flexible wire is limited by the retainer, which facilitates the transmission of electrical signals by the flexible wire and limits the position of the flexible wire. By setting a deformation segment on the flexible wire, and because the flexible wire is flexible, the position of the flexible wire can be easily adjusted. By setting a deformation segment, the flexible wire has deformation capability, so that during the position shift process, the flexible wire drives the first pin and the first housing component to shift or swing relative to the retainer, which facilitates the adjustment of the position of the first pin and the first housing component. When the first terminal and the second terminal are connected, the deformation of the flexible wire facilitates the assembly of the first pin and the first housing component with the second terminal. This is beneficial for the first pin to compensate for the assembly tolerance between the first terminal and the second terminal during the assembly process, and facilitates the realization of a stable electrical connection between the first conductive component and the second conductive component.

[0030] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments will be further described in detail below with reference to the accompanying drawings. In this document, relational terms such as "first" and "second" are used merely to distinguish one component from another that has the same name, and do not necessarily require or imply any such actual relationship or order between these components.

[0031] The thermal management system includes a coolant system and a refrigerant system. It includes heat exchange components such as evaporators or condensers. The coolant in the coolant system and the refrigerant in the refrigerant system can exchange heat in these heat exchange components, for example, in an evaporator or condenser. The coolant or refrigerant can flow in the loop of the thermal management system to achieve its heat exchange function. In this embodiment, the thermal management system can be a vehicle thermal management system, capable of exchanging heat for the battery, motor, passenger compartment, etc. Alternatively, the thermal management system in this embodiment can also be an energy storage thermal management system.

[0032] Based on this, such as Figures 1 to 4 As shown, this embodiment of the invention provides a thermal management device 1, which includes a coolant assembly. The coolant assembly includes a flow channel plate assembly 500, a fluid assembly 400, and a drive component 300. The drive component 300 can drive the fluid assembly 400 to operate. The fluid assembly 400 may include at least one of a pump assembly 71 and a valve assembly 72. Correspondingly, the drive component 300 includes at least one of a pump drive assembly 73 and a valve drive assembly 74. The pump drive assembly 73 drives the pump assembly 71 to rotate to allow fluid flow, and the valve drive assembly 74 drives the valve assembly 72 to operate to achieve flow path switching or proportional adjustment. The pump assembly 71 includes an impeller assembly, and the pump drive assembly 73 can drive the impeller assembly to rotate. The valve assembly 72 includes a valve core and a seal, and the valve drive assembly 74 can drive the valve core to rotate. At least a portion of the fluid assembly 400 may be located within a receiving cavity defined by the flow channel plate assembly 500, or the fluid assembly 400 may be sealed and limited to the flow channel plate assembly 500.

[0033] The flow channel plate assembly 500 includes at least two flow channel plates, including a first flow channel plate 51. The flow channel plate assembly 500 has a fluid passage, and the first flow channel plate 51 defines a wall portion of the fluid passage. The first flow channel plate 51 has at least one of a pump chamber and a valve chamber. At least a portion of the pump assembly 71 may be located in the pump chamber, and at least a portion of the valve assembly 72 may be located in the valve chamber. The fluid passage of the flow channel plate assembly 500 enables communication between the pump assembly 71 and the valve assembly 72, facilitating fluid interaction between them. This configuration reduces or eliminates the piping between the pump assembly 71 and the valve assembly 72, improving the integration of the thermal management device 1.

[0034] As the number of components that need to be managed by the thermal management device 1 increases, the modes of the thermal management device 1 increase, the number of pump assembly 71 and valve assembly 72 increases, and the number of corresponding pump drive assembly 73 and valve drive assembly 74 gradually increases. In order to control the pump drive assembly 73 and valve drive assembly 74, multiple wiring harness structures need to be set up to be electrically connected to the pump drive assembly 73 and valve drive assembly 74 respectively, which occupies a large space and has a high cost.

[0035] Please refer to further information. Figures 1 to 8 To address the aforementioned issues, in this embodiment of the invention, the thermal management device 1 further includes a control component 200. The control component 200 includes a circuit board 30, which can be electrically connected to at least two drive components 300, facilitating a reduction in wiring harness structure. In this embodiment, the circuit board 30 can be a printed circuit board assembly (PCBA). All drive components 300 corresponding to all fluid components 400 of the thermal management device 1 can be electrically connected to the same circuit board 30, facilitating control of the motor 301 within the drive components 300 through a single circuit board 30, thereby improving the domain control integration of the thermal management device 1. This configuration allows the thermal management device 1 to have an external connector, through which the wiring harness structure can supply power to the circuit board 30, further reducing the wiring harness structure.

[0036] In some embodiments, the number of driving components 300 is at least two, and one driving component 300 drives the corresponding fluid component 400 to operate. The control component 200 includes at least two sets of first conductive elements and a circuit board 30. Each set of first conductive elements includes a plurality of first conductive elements 12, for example... Figure 3 In the process, a group of first conductive elements includes four first conductive elements 12. A group of first conductive elements 12 is electrically connected to a corresponding second conductive element 22 of a driving component 300. At least two groups of first conductive elements 12 are electrically connected to the circuit board 30, and at least two second conductive elements 22 in the driving components 300 are electrically connected to the corresponding first conductive elements 12, which facilitates improving the domain control integration of the thermal management device 1.

[0037] In a specific implementation, the control component 200 may include at least two sets of first conductive element groups, each set of first conductive element groups including multiple first conductive elements 12. Each set of first conductive element groups is electrically connected to a second pin in a corresponding drive component 300, so that the circuit board 30 can control the operation of the motor 301 of a drive component 300 through a set of first conductive element groups. For example, in this embodiment, the first conductive element group corresponding to the pump drive assembly 73 includes four first conductive elements 12, and the pump drive assembly 73 includes four second conductive elements 22. The first conductive elements 12 and the second conductive elements 22 can correspond one-to-one and be electrically connected. Each first conductive element 12 is electrically connected to the circuit board 30, and each drive component 300 includes a motor 301 and multiple second conductive elements 22. The second conductive elements 22 are electrically connected to the motor 301. The second conductive elements 22 are abutted, contacted, or welded to the corresponding first conductive elements 12 to achieve electrical connection between them. With the above configuration, a single circuit board 30 can control the motors 301 in at least two drive components 300, and the motors are electrically connected via the first conductive element 12 and the second conductive element 22. This reduces the wiring harness structure between the control component 200 and the drive component 300, and also reduces the need for a separate circuit board for each drive component 300, thus lowering costs. In this embodiment of the invention, electrical connection between two components means that electrical signals can be transmitted between the two components, including but not limited to contact, contact, welding, or a predetermined distance between the two components, as long as electrical signals can be transmitted between them.

[0038] like Figures 2 to 6 As shown, at least a portion of the first conductive element 12 is disposed in the control component 200, and the first conductive element 12 is electrically connected to the circuit board 30. The control component 200 includes a control housing with a control cavity 54. The circuit board 30 is located in the control cavity 54, and the circuit board 30 can be limitedly connected to the control housing. Optionally, the circuit board 30 can be fixed to the control housing by riveting or bolting to form an integral unit. At least a portion of the second conductive element 22 is disposed in the drive component 300. One of the second conductive element 22 and the first conductive element 12 is inserted into the other, and the first conductive element 12 and the second conductive element 22 are in contact or abut against each other to realize the electrical connection between the first conductive element 12 and the second conductive element 22, thereby enabling the current and electrical signals of the circuit board 30 to be transmitted to the motor 301 via the first conductive element 12 and the second conductive element 22.

[0039] Since the first conductive element 12 and the second conductive element 22 are respectively disposed in two components, and since the first conductive element 12 itself is prone to tolerances during manufacturing and assembly with the circuit board 30, or during assembly with the PCBA board and the control housing, the first conductive element 12 has a first tolerance. The first tolerance is the tolerance perpendicular to the plane where the extension direction of the first conductive element 12 is located, that is, the first tolerance is the tolerance of the first conductive element 12. Figure 5 The tolerance in the YZ plane. Similarly, the second conductive component 22 itself is prone to a second tolerance during manufacturing and assembly, that is, the second tolerance is an additional tolerance. Figure 5 The tolerance in the YZ plane causes the first conductive element 12 and the second conductive element 22 to have a third tolerance during assembly. This third tolerance is related to the first tolerance and the second tolerance. Optionally, the third tolerance is the sum of the first tolerance and the second tolerance.

[0040] Please refer to further information. Figures 1 to 9 This application provides an electrical connection assembly 100, which includes a first terminal 10 and a second terminal 20. The first terminal 10 has a first housing 11 and a first conductive element 12. The second terminal 20 includes a second housing 21 and a second conductive element 22. The second conductive element 22 is fixedly connected to the second housing 21. One of the second housing 21 and the first housing 11 is embedded in the other. The second conductive element 22 is electrically connected to a first pin 120.

[0041] To compensate for the tolerance between the first conductive element 12 and the second conductive element 22, the first conductive element 12 includes a first pin 120 and a flexible wire 123. At least a portion of the first pin 120 is positioned within the insertion portion 110. For example, the first pin 120 can be injection molded into the insertion portion 110 as an insert, or the first pin 120 can be assembled into the insertion portion 110. The first pin 120 can be a metal part, for example, the first pin 120 can be a plate-like structure.

[0042] The flexible conductor 123 can be easily bent or deformed at multiple angles; for example, the flexible conductor 123 can be a multi-core cable. To limit the position of the flexible conductor 123, in some embodiments, the first terminal 10 further includes a retainer 13, and the first housing 11 includes a plug portion 110, which is spaced apart from the retainer 13 along a first direction XX. A second direction YY is defined to intersect the first direction XX, and a third direction ZZ intersects both the first direction XX and the second direction YY. The flexible conductor 123 includes a first connecting segment 1231, a second connecting segment 1233, and a deformation segment 1232. The deformation segment 1232 is connected between the first connecting segment 1231 and the second connecting segment 1233. The first pin 120 is fixedly connected to and electrically connected to the first connecting segment 1231, and the second connecting segment 1233 is limited by the retainer 13. At least a portion of the deformable segment 1232 is supported between the insertion portion 110 and the retainer 13. The deformable segment 1232 is configured to have a deformable capability to cause the first pin 120 and the first housing member 11 to shift or swing relative to the retainer 13. Through this configuration, the flexible wire 123 is flexible, making its position easily adjustable. By providing the deformable segment 1232 with a deformable capability, the flexible wire 123 causes the first pin 120 and the first housing member 11 to shift or swing relative to the retainer during position shifting, facilitating the adjustment of the positions of the first pin 120 and the first housing member 11. When the first terminal 10 is used for mating with the second terminal 20, the deformation of the flexible wire 123 facilitates the assembly of the first pin 120 and the first housing member 11 with the second terminal 20, which helps to compensate for the assembly tolerance between the first pin 120 and the second conductive member 22 during assembly.

[0043] In some embodiments, the electrical connection assembly 100 further includes a circuit board 30, which is electrically connected to the second connection segment 1233, such that the electrical signal or control signal of the circuit board 30 is transmitted to the second conductive element 22 through the first conductive element 12.

[0044] To enhance the deformability of the deformable segment 1232, in some embodiments, the deformable segment 1232 includes a first sub-segment S1 and a second sub-segment S2, wherein the extension direction of the first sub-segment S1 intersects the extension direction of the second sub-segment S2, such as... Figure 4As shown, the first sub-segment S1 and the second sub-segment S2 extend in a curved manner. Further, the extension direction of the first sub-segment S1 intersects the extension direction of the first connecting segment 1231, and the extension direction of the second sub-segment S2 intersects the extension direction of the second connecting segment 1233. The first sub-segment S1 and the second sub-segment S2 are flexibly connected; the first sub-segment S1 is flexibly connected to the first connecting segment 1231, and the second sub-segment S2 is flexibly connected to the second connecting segment 1233. The first sub-segment S1 can be offset or oscillated relative to the second sub-segment S2, and the second sub-segment S2 can be offset or oscillated relative to the second connecting segment 1233. With the above arrangement, the first pin 120 and the first housing member 11 can be offset or oscillated relative to the retainer 13 via the deformable segment 1232.

[0045] In practical implementation, the first sub-segment S1, the second sub-segment S2, the first connecting segment 1231, and the second connecting segment 1233 are integrated into a single structure. Adjusting the extension angle between the first sub-segment S1 and the second sub-segment S2 facilitates adjusting the position of the first pin 120 and the first housing 11 relative to the retainer 13, thereby facilitating the adjustment of the relative position of the first terminal 10 relative to the second terminal 20 and helping to compensate for assembly tolerances between the first terminal 10 and the second terminal 20. By setting the extension directions of the first sub-segment S1 and the second sub-segment S2 to intersect, the deformable segment 1232 can have a longer unfolded length, allowing it to switch between bending and stretching. This enables the relative distance between the insertion part 110 and the retainer 13 to decrease or increase, reducing the risk of damage to the flexible wire 123 due to pulling during offset or oscillation of the insertion part 110.

[0046] In some embodiments, the first terminal 10 has at least two first conductive elements 12 arranged side-by-side along the second direction YY, with the first sub-segment S1 and the second sub-segment S2 curved together in an arc. To further improve the support performance of the deformable segments 1232 on the insertion portion 110 and to stabilize the insertion and extraction forces of the first terminal 10 and the second terminal 20 during mating, along the third direction ZZ, a portion of the deformable segments 1232 are bent and protruded toward the first side of the insertion portion 110, and another portion of the deformable segments 1232 are bent and protruded toward the second side of the insertion portion 110, with the first and second sides of the insertion portion 110 facing each other along the third direction ZZ. In specific implementations, such as Figure 4 and Figure 5 As shown, the bending directions of the deformation sections 1232 of the two adjacent first conductive parts 12 are opposite, which helps to reduce the insertion and extraction force of the first terminal 10 and the second terminal 20 during the insertion process. This makes the force uniform when the first terminal 10 and the second terminal 20 are assembled, and also helps to make the insertion part 110 more uniformly stressed.

[0047] Furthermore, when the first terminal 10 has at least two first conductive elements 12 arranged side-by-side along the second direction YY, to prevent mutual interference between the first conductive elements 12, the plug-in portion 110 has at least two independent first chambers 111, with at least a portion of each first conductive element 12 located in a corresponding first chamber 111. The plug-in portion 110 also includes creepage bumps 112 located between adjacent first chambers 111, and the shortest path of the creepage bumps 112 is greater than the creepage distance between two adjacent first conductive elements 12. This configuration facilitates the reduction of electrical signal interference between adjacent first conductive elements 12.

[0048] Since the flexible conductor 123 can cause the position of the first housing member 11 to shift or swing relative to the retainer 13, limiting the extreme positions of the shift or swing of the first housing member 11 is beneficial to improving the mating assembly efficiency between the first terminal 10 and the second terminal 20. In some embodiments, the retainer 13 includes an end frame 131 and a side frame 132. The arrangement direction between the end frame 131 and the insertion portion 110 is defined as a first direction XX, the side frame 132 protrudes from the end frame 131 along the first direction XX, and the deformable segment 1232 is located between the end frame 131 and the insertion portion 110. The first housing member 11 also includes a first limiting portion 113, which protrudes from the insertion portion 110 along the first direction XX. Along the first direction XX, at least a portion of the first limiting portion 113 is disposed facing the side frame 132. The at least portion of the first limiting portion 113 disposed facing the side frame 132 is capable of shifting or swinging towards or away from the side frame 132. The side frame 132 is configured such that the first limiting portion 113 abuts against the side frame 132 to limit the offset end position or swing end position of the first limiting portion 113, so as to facilitate limiting the offset limit position or swing limit position of the first housing member 11.

[0049] In some embodiments, the number of first limiting portions 113 is at least two. The arrangement direction of the first limiting portions 113 facing each other and the side frames 132 is defined as the second direction YY, which intersects with the first direction XX. Along the second direction YY, at least two first limiting portions 113 are spaced apart on both sides of the insertion portion 110. Based on this, the number of side frames 132 is at least two. Along the second direction YY, at least two side frames 132 are spaced apart on both sides of the end frame 131, and at least two first limiting portions 113 are located within the space defined by at least two side frames 132. By abutting the first limiting portion 113 against the facing side frame 132, the offset limit position or swing limit position of the first limiting portion 113 along the second direction YY can be limited. Through the above arrangement, not only can the first housing member 11 be offset or swing within a predetermined distance, but it can also prevent the first housing member 11 from being too offset, causing the deformation section 1232 to be stretched and break.

[0050] Furthermore, to limit the offset end position or swing end position of the first housing member 11 along the third direction ZZ, in some embodiments, the first housing member 11 further includes a second limiting part 114, which is connected to at least one of the insertion part 110 and the first limiting part 113. Optionally, as... Figure 5 As shown, the second limiting part 114 is connected to the side of the first limiting part 113 away from the insertion part 110, and the second limiting part 114 protrudes towards the side frame 132. The side frame 132 has a receiving cavity 134, at least a portion of the second limiting part 114 is located in the receiving cavity 134, and the direction intersecting both the first direction XX and the second direction YY is defined as the third direction ZZ. Along the third direction ZZ, the second limiting part 114 can offset or swing within the receiving cavity 134. The wall of the receiving cavity 134 is configured such that the wall of the receiving cavity 134 abuts against the second limiting part 114 to limit the offset end position or swing end position of the second limiting part 114 along the third direction ZZ.

[0051] In a specific implementation, the second limiting part 114 has two side parts arranged along the third direction ZZ. These two side parts are arranged opposite to the two side surfaces of the limiting cavity 134. When the side parts abut against the side surfaces, they can limit the offset end position or swing end position of the second limiting part 114 along the third direction ZZ, which is beneficial to limit the offset end position or swing end position of the first housing part 11 along the third direction ZZ.

[0052] like Figure 5As shown, to prevent the second limiting portion 114 from dislodging from the receiving cavity 134 during the offset or swinging process, in some embodiments, a portion of the second limiting portion 114 protrudes from the outer surface of the side frame 132. The first housing member 11 also includes a third limiting portion 115, which is connected to the side of the second limiting portion 114 that protrudes from the outer surface of the side frame 132. At least a portion of the third limiting portion 115 is projected onto the side frame 132 outside the receiving cavity 134. Optionally, the size of the third limiting portion 115 may be larger than the size defining the receiving cavity 134. When the first limiting portion 113 is in the offset end position or the swing end position, the third limiting portion 115 has a gap or contact arrangement with the outer surface of the side frame 132 to reduce or prevent the influence of the third limiting portion 115 on the offset or swinging distance of the first housing 11, thereby improving the stability of the insertion of the first terminal 10 and the second terminal 20.

[0053] To facilitate the assembly of the retainer 13 with the flexible wire 123 and the first housing component 11, combined with Figures 4 to 11 As shown, in some embodiments, the retainer 13 includes a first support frame 13a and a second support frame 13b, which are connected in a limiting manner. Both the first support frame 13a and the second support frame 13b define portions of the end frame 131 and the side frame 132. That is, after the first support frame 13a and the second support frame 13b are assembled, the end frame 131 and the side frame 132 of the retainer 13 are formed. The retainer 13 has a limiting cavity 133, and a second connecting segment 1233 is positioned within the limiting cavity 133. Both the first support frame 13a and the second support frame 13b define portions of the wall of the limiting cavity 133.

[0054] In a specific implementation, the wall surface of the limiting cavity 133 may have concave and convex surfaces, which are spaced apart along the outer periphery of the limiting cavity 133. For example, the wall surface of the limiting cavity 133 may have a toothed portion or a wavy portion. With the above configuration, the wall surface of the limiting cavity 133 can abut against the second connecting segment 1233, thereby improving the limiting stability of the cage 13 on the second connecting segment 1233.

[0055] In some embodiments, the retainer 13 includes a first support frame 13a and a second support frame 13b, at least a portion of the first support frame 13a and at least a portion of the second support frame 13b being arranged in a third direction ZZ. The first support frame 13a and the second support frame 13b are snap-fitted together. For example, the first support frame 13a has a first hook, and the second support frame 13b has a second hook. The first hook and the second hook cooperate to define a snap-fit ​​structure to achieve the connection between the first support frame 13a and the second support frame 13b.

[0056] Furthermore, to achieve the limiting of the flexible conductor 123 by the first support frame 13a and the second support frame 13b, such as... Figure 10 As shown, in some embodiments, along the thickness direction of the first support frame 13a, the bottom of the first support frame 13a has a first docking portion 13a0, the first docking portion 13a0 includes at least one first groove docking portion 13a1 and at least one first protrusion docking portion 13a2, the at least one first groove docking portion 13a1 and the at least one first protrusion docking portion 13a2 are arranged adjacent to each other.

[0057] like Figure 11 As shown, along the thickness direction of the second support frame 13b, the bottom of the second support frame 13b has a second mating portion 13b0. The second mating portion 13b0 includes at least one second grooved mating portion 13b1 and at least one second protruding mating portion 13b2. The at least one second grooved mating portion 13b1 and the at least one second protruding mating portion 13b2 are arranged adjacent to each other. The first grooved mating portion 13a1 and the second protruding mating portion 13b2 are interlocked to limit the position of the second connecting segment 1233, and the second grooved mating portion 13b1 and the first protruding mating portion 13a2 are interlocked to limit the position of the second connecting segment 1233. Through the above arrangement, the positions of the first support frame 13a and the second support frame 13b can be limited, and it is convenient to limit the position of the flexible conductor 123. The above settings can limit the position of the second connecting segment 1233. When the second connecting segment 1233 is electrically connected to the circuit board 30, it is convenient to improve the positional stability between the second connecting segment 1233 and the circuit board 30, which is beneficial to improving the electrical connection stability between the second connecting segment 1233 and the circuit board 30.

[0058] like Figure 10 As shown, in some embodiments, along the thickness direction of the first support frame 13a, the first support frame 13a has at least two layers of first docking portions 13a0. The projection of the first protruding docking portion 13a2 located in one layer of the first docking portion 13a0 and the projection of the first protruding docking portion 13a2 located in the other layer of the first docking portion 13a0 are arranged side by side. The projection of the first groove docking portion 13a1 located in one layer of the first docking portion 13a0 and the projection of the first groove docking portion 13a1 located in the other layer of the first docking portion 13a0 are arranged side by side.

[0059] Accordingly, such as Figure 11As shown, along the thickness direction of the second support frame 13b, the second support frame 13b has at least two layers of second mating portions 13b0. Projecting along the thickness direction of the end frame 131, the projections of the second protruding mating portion 13b2 located in one layer of the second mating portion 13b0 and the second protruding mating portion 13b2 located in the other layer of the second mating portion 13b0 are arranged side-by-side. Similarly, the projections of the second grooved mating portion 13b1 located in one layer of the second mating portion 13b0 and the second grooved mating portion 13b1 located in the other layer of the second mating portion 13b0 are arranged side-by-side. In the first mating portion 13a0 and the second mating portion 13b0 connected in the same layer, the first grooved mating portion 13a1 and the second protruding mating portion 13b2 are connected to limit the second connecting segment 1233, and the second grooved mating portion 13b1 and the first protruding mating portion 13a2 are connected to limit the second connecting segment 1233. By providing at least two layers of first mating portions 13a0 and at least two layers of second mating portions 13b0, the position of the second connecting segment 1233 along the second direction YY can be limited, and the coaxiality between the second connecting segment 1233 and the wall surface of the limiting cavity 133 can be improved. This reduces or prevents the second connecting segment 1233 from being tilted relative to the end frame portion 131, thereby improving the positional accuracy of each second connecting segment 1233. This facilitates accurate relative positioning between the second connecting segment 1233 and the electrical connection point of the circuit board 30, enabling electrical connection between the second connecting segment 1233 and the circuit board 30. For example, the second connecting segment 1233 and the circuit board 30 can be electrically connected by soldering. Furthermore, by setting the second connecting segment 1233 perpendicular to the end frame 131, it is beneficial to support the first housing member 11 through the flexible wire 123, facilitating the offset or swing of the first housing member 11 for mating connection with the second terminal 20.

[0060] In specific implementation, such as Figure 5As shown, the number of first conductive elements 12 in the first terminal 10 can be four. Correspondingly, along the thickness direction of the first support frame 13a, the bottom of the first support frame 13a has two layers of first mating portions 13a0. Each layer of first mating portions 13a0 includes at least two first grooved mating portions 13a1 and two first protruding mating portions 13a2, with one first grooved mating portion 13a1 and one first protruding mating portion 13a2 arranged in a cycle. Along the thickness direction of the second support frame 13b, the bottom of the second support frame 13b has two layers of second mating portions 13b0. Each layer of second mating portions 13b0 includes two second grooved mating portions 13b1 and two second protruding mating portions 13b2, with one second grooved mating portion 13b1 and one second protruding mating portion 13b2 arranged in a cycle. Optionally, the number of the first groove mating portion 13a1 and the second protruding mating portion 13b2 can be the same, and the number of both the first groove mating portion 13a1 and the second protruding mating portion 13b2 can be greater than or equal to the number of the first conductive element 12. The number of the first protruding mating portion 13a2 and the second groove mating portion 13b1 can be the same, and the number of both the first protruding mating portion 13a2 and the second groove mating portion 13b1 can be greater than or equal to the number of the first conductive element 12.

[0061] Please refer to further information. Figures 9 to 11 In some embodiments, the first groove mating portion 13a1 includes at least two spaced-apart first grooves a11, with the wall surface of the limiting cavity 133 located between the two first grooves a11. The first protruding mating portion 13a2 includes at least two spaced-apart first protrusions a21, with the wall surface of the limiting cavity 133 located between the two first protrusions a21. The second groove mating portion 13b1 includes at least two spaced-apart second grooves b11, with the wall surface of the limiting cavity 133 located between the two second grooves b11. The second protruding mating portion 13b2 includes at least two spaced-apart second protrusions b22, with the wall surface of the limiting cavity 133 located between the two second protrusions b22. With the above configuration, the second connecting segment 1233 can be limited after the first groove mating portion 13a1 and the second protruding mating portion 13b2 are interlocked, and after the second groove mating portion 13b1 and the first protruding mating portion 13a2 are interlocked.

[0062] In specific implementation, the first protrusion a21 has a root and an extended end, with the width of the first protrusion a21 decreasing from the root to the extended end. The structure of the second protrusion b22 is the same as or similar to that of the first protrusion a21, and will not be described in detail. The extended ends of both the second protrusion b22 and the first protrusion a21 are rounded. The structure of the first protrusion a21 matches the shape of the second groove b11, and both can be toothed structures. The structure of the second protrusion b22 matches the shape of the first groove a11, and both can be toothed structures.

[0063] Please refer to further information. Figures 9 to 11 To improve the structural strength of the side component 132 and limit the offset or swinging position of the second limiting part 114, in some embodiments, the side frame 132 includes a first side frame 13c1 and a second side frame 13c2, which are inserted together to define the side frame 13. In the inserted side frame 13c1 and the second side frame 13c2, one of the first side frame 13c1 and the second side frame 13c2 is located in the first support frame 13a, and the other of the first side frame 13c1 and the second side frame 13c2 is located in the second support frame 13b. The side frame 132 has a receiving cavity 134, and both the first side frame 13c1 and the second side frame 13c2 define a portion of the wall of the receiving cavity 134. This arrangement facilitates the insertion and engagement of the first support frame 13a and the second support frame 13b.

[0064] Specifically, the first side frame 13c1 includes a mating groove c11, and the second side frame 13c2 includes an interlocking protrusion c21. At least a portion of the interlocking protrusion c21 is inserted into the mating groove c11, thereby limiting the mutual positioning of the first side frame 13c1 and the second side frame 13c2. Further, the mating groove c11 is located on the side of the wall defining the receiving cavity 134 away from the end frame 131. In this case, when at least a portion of the interlocking protrusion c21 is inserted into the mating groove c11, both the interlocking protrusion c21 and the wall portion defining the mating groove c11 can limit the second limiting portion 114 inserted into the receiving cavity 134. This helps maintain the structural strength of the frame 13 and improves the limiting strength of the second limiting portion 114.

[0065] Furthermore, to facilitate the limiting of the two second limiting portions 114 located on both sides of the insertion portion 110 along the second direction YY, in some embodiments, the first side frame 13c1 is located on the first side of the first support frame 13a, the second side frame 13c2 is located on the second side of the first support frame 13a, the second side frame 13c2 is located on the first side of the second support frame 13b, and the first side frame 13c1 is located on the second side of the second support frame 13b. The first side of the first support frame 13a and the first side of the second support frame 13b are arranged opposite to each other, and the second side of the second support frame 13b is arranged opposite to each other. The first side frame 13c1 and the second side frame 13c2 located on the same side are inserted and fitted together. At this time, the first support frame 13a and the second support frame 13b can have the same structure. They can be the same structural components, which simplifies the types of parts in the electrical connection assembly 100 and the thermal management device 1, and simplifies the manufacturing process of the electrical connection assembly 100 and the thermal management device 1.

[0066] To enhance the connection stability of the first support frame 13a and the second support frame 13b and prevent them from detaching from each other, in some embodiments, the first side frame 13c1 and the second side frame 13c2 are snap-fitted together, and / or, the bottom of the first support frame 13a is snap-fitted together with the bottom of the second support frame 13b. For example... Figures 9 to 11 As shown, the first support frame 13a has a first hook, and the second support frame 13b has a second hook, which engage with each other. Both the first support frame 13a and the second support frame 13b can be made of plastic.

[0067] To achieve stable transmission of electrical signals, such as Figure 9 As shown, in some embodiments, at least a portion of the first pin 120 is located on one side of the first connecting segment 1231, and the first pin 120 is soldered to the first connecting segment 1231. Alternatively, as... Figure 12 As shown, the first pin 120 includes a mounting portion 1201, which has a mounting cavity 1202 and a disconnection port 1203 communicating with the mounting cavity 1202. At least a portion of the first connecting segment 1231 is located in the mounting cavity 1202, and the mounting portion 1201 is clamped to the first connecting segment 1231. This configuration facilitates a stable electrical connection between the first pin 120 and the first connecting segment 1231. The first pin 120 and the first connecting segment 1231 can then be connected by crimping.

[0068] like Figure 9 As shown, in some embodiments, the first pin 120 includes a first pin segment 121 and a second pin segment 122, which are bent. The first pin segment 121 is located on one side of the first connecting segment 1231 and is welded to the first connecting segment 1231, for example, by soldering or ultrasonic welding. The projection of the second pin segment 122 onto the first connecting segment 1231 at least partially overlaps with the first connecting segment 1231. Figure 9 As shown, the first needle segment 121 is welded to one side of the first connecting segment 1231 in the radial direction, and the second needle segment 122 is bent from the first needle segment 121 toward the center line of the first connecting segment 1231, which helps to reduce the space occupied by the first conductive element 12.

[0069] To achieve the limiting of the first pin 120 and the insertion part 110, combined with Figure 7 , Figure 9 , Figures 13 to 16As shown, the first pin segment 121 includes a first protrusion 1211, which has a first guide surface 1210. The width of the first guide surface 1210 decreases along the direction from the first pin segment 121 to the second pin segment 122. The second pin segment 122 includes a second protrusion 1221. The first protrusion 1211 and the second protrusion 1221 are located at different heights of the insertion portion 110, i.e., the first protrusion 1211 and the second protrusion 1221 are arranged along the height direction of the insertion portion 110. Figure 9 As shown, due to the bent arrangement of the first needle segment 121 and the second needle segment 122, the second protrusion 1221 and the first protrusion 1211 are positioned relative to each other. Correspondingly, the insertion portion 110 includes a first stepped surface 116 and a second stepped surface 117. Along the height direction of the insertion portion 110, the projection of the first stepped surface 116 and the projection of the second stepped surface 117 are misaligned. The first protrusion 1211 and the second protrusion 1221 are both limited and positioned between the first stepped surface 116 and the second stepped surface 117, as shown. Figure 16 As shown, at this time, the second step surface 117 can limit the upper limit position of the first pin 120. When the first step surface 116 abuts against the first protrusion 1211, it can prevent the first pin 120 from coming out of the plug-in part 110. Through the above settings, it is beneficial to limit the first pin 120 to the plug-in part 110.

[0070] When the first terminal 10 mates with the second terminal 20, the second conductive element 22 included in the second terminal 20 can be a flat metal needle structure. To connect the first conductive element 12 and the second conductive element 22 for transmitting electrical signals, in some embodiments, such as... Figure 7 , Figures 12 to 16 As shown, the second needle segment 122 also includes a first sub-part 1222 and a second sub-part 1223 spaced apart. One of the first sub-part 1222 and the second sub-part 1223 is inclined toward the other. The first sub-part 1222 includes at least one first conductive protrusion E1, and the second sub-part 1223 includes at least one second conductive protrusion E2. The first conductive protrusion E1 and the second conductive protrusion E2 are arranged opposite each other or offset. The first conductive protrusion E1 and the second conductive protrusion E2 are convenient to abut against the second conductive member 22 to achieve electrical connection.

[0071] When the second terminal 20 is plugged into the first terminal 10, the plug-in portion 110 and the second housing member 21 can be guided to align their positions. Based on this, please refer to... Figure 7 , Figure 15 and Figure 16As shown, the insertion portion 110 of this embodiment further includes a second guide surface 1181, a connecting surface 1182, and a third stepped surface 1183. The second guide surface 1181 is located at the end of the insertion portion 110 away from the retainer 13. The third stepped surface 1183 is located on the side of the second guide surface 1181 near the second pin segment 122. Along the direction from the second pin segment 122 to the first pin segment 121, the opening size of the second guide surface 1181 decreases. The connecting surface 1182 is disposed between the third stepped surface 1183 and the second guide surface 1181. With the above arrangement, the second conductive member 22 can be guided by the second guide surface 1181, facilitating the insertion of the second conductive member 22 into the insertion portion 110. Furthermore, there is a gap between the third stepped surface 1183 and the end of the first conductive member 12, and the third stepped surface 1183 and the second guide surface 1181 have a connecting surface 1182, which improves the structural strength of the insertion portion 110.

[0072] To limit the first pin 120 to be positioned in the insertion portion 110, the insertion portion 110 has the same number of independent first chambers 111 as the first pin 120. Each first chamber 111 includes a first sub-chamber 1111, a second sub-chamber 1112, and a third sub-chamber 1113 that are in communication with each other. The first sub-chambers 1111 and 1112 are arranged opposite to each other, and the third sub-chamber 1113 may be arranged perpendicular to the first sub-chamber 1111. At least a portion of the first sub-part 1222 may be located in the first sub-chamber 1111, and the second sub-part 1223 may be located in the second sub-chamber 1112. The second conductive element 22 of the second terminal 20 can be inserted into the third sub-chamber 1113.

[0073] In some embodiments, the electrical connection assembly 100 further includes a circuit board 30 located on the side of the retainer 13 opposite to the insertion portion 110. The retainer 13 also includes a connecting post 136 riveted to the circuit board 30 to achieve a fixed connection between the retainer 13 and the circuit board 30, and the second connecting segment 1233 is electrically connected to the circuit board 30. For example, the connecting post 136 and the circuit board 30 can be fixedly connected by a thermal riveting process.

[0074] When the retainer 13 also includes a first support frame 13a and a second support frame 13b, and the first support frame 13a and the second support frame 13b also include a snap-fit ​​structure 135, the end face of the snap-fit ​​structure 135 abuts against the circuit board 30 and is riveted to the circuit board 30 through the connecting post 136, so that the end face of the snap-fit ​​structure 135 is always in contact with the circuit board 30, preventing one of the snap hooks of the snap-fit ​​structure 135 from disengaging from the other snap hook.

[0075] In some embodiments, the retainer 13 includes an end frame 131 and a side frame 132. The first housing member 11 further includes a first limiting portion 113 and a second limiting portion 114. The arrangement direction between the end frame 131 and the insertion portion 110 is defined as a first direction XX, and the arrangement direction between the first limiting portion 113 and the side frame 132 is defined as a second direction YY. Along the second direction YY, the maximum tolerance between the first conductive member 12 and the second conductive member 22 is X1, the unfolded length of the deformable segment 1232 is L1, and the gap between the insertion portion 110 and the retainer 13 is H1. 2 ≥H1 2 +X1 2 The above settings facilitate the setting of a reasonable length for the deformation segment 1232, so as to meet the assembly tolerance between the first terminal and the second terminal.

[0076] When the insertion part 110 is centered relative to the retainer 13, the gap between the first limiting part 113 and the side frame 132, which are directly opposite each other, is d1, where d1 ≥ X1. The side frame 132 has a receiving cavity 134, and at least a portion of the second limiting part 114 is located in the receiving cavity 134. The third direction ZZ is defined to intersect both the first direction XX and the second direction YY. Along the third direction ZZ, the maximum tolerance between the first conductive member 12 and the second conductive member 22 is X2. When the second limiting part 114 is centered relative to the side frame 132, the gap between the second limiting part 114 and the wall of the receiving cavity 134 is d2, where d2 ≥ X2. At this time, L1... 2 ≥H1 2 +X2 2 With the above configuration, the first limiting part 113 and the second limiting part 114 can compensate for the tolerance between the first terminal and the second terminal within the offset or swing stroke range.

[0077] Furthermore, such as Figure 3 As shown, when the second terminal 20 and the first terminal 10 are assembled in place, there may be a gap between the top surface of the plug portion 110 and the inner ground surface of the second housing component 21 along the first direction XX, and there may be a gap between the free end of the second conductive component 22 and the first conductive component 12 along the first direction XX, so as to facilitate the assembly between the second terminal 20 and the first terminal 10.

[0078] On the other hand, embodiments of the present invention provide a thermal management device 1, including the aforementioned electrical connection assembly 100. It is understood that the aforementioned electrical connection assembly 100 can also be used in other structures requiring the connection of electrical components, such as controller plug-ins.

[0079] In some embodiments, the thermal management device 1 further includes a flow channel plate assembly 500 having a coolant channel. A channel of the fluid assembly 400 communicates with the coolant channel. The flow channel plate assembly 500 includes a first flow channel plate 51 defining a portion of the coolant channel wall. The thermal management device 1 also includes a cover plate 53 disposed adjacent to the drive component 300. The cover plate 53 and the first flow channel plate 51 are sealed together to define a control cavity 54. At least a portion of the first terminal 10 and the circuit board 30 are located in the control cavity 54. The number of fluid assemblies 400 is at least two. The thermal management device 1 has drive components corresponding to the at least two fluid assemblies 400. Second conductive elements 22 of the at least two drive components are electrically connected to the same circuit board 30 via first conductive elements 12. The fluid assembly 400 includes at least one of a pump assembly, a valve assembly, and a sensor assembly.

[0080] Please combine further Figures 1 to 3 , Figures 17 to 18 As shown, in some embodiments, a portion of the first terminal 10 is exposed to the cover plate 53. The electrical connection assembly 100 also includes a second terminal 20 having a second housing member 21. The thermal management device 1 also includes a seal 600, which includes a first sealing portion 61, a second sealing portion 62, and an elastic portion 63. The elastic portion 63 is connected between the first sealing portion 61 and the second sealing portion 62. The first sealing portion 61 is sleeved outside the second housing member 21 and the first sealing portion 61 and the second housing member 21 are sealed together. The second sealing portion 62 is sleeved outside the cover plate 53 and the second sealing portion 62 is sealed together with the cover plate 53. The elastic portion 63 is capable of adjusting the relative arrangement of the first sealing portion 61 and the second sealing portion 62. Through the above configuration, the circuit board 30 can input control electrical signals to the motor 301 via the first conductive element 12 and the second conductive element 22. This facilitates the circuit board 30's control over the operation of the motor 301, making it easier for the motor 301 to drive the fluid assembly 400. Furthermore, by electrically connecting the first conductive element 12 and the second conductive element 22, the wiring harness structure between the drive component 300 and the control component 200 can be omitted. Moreover, by providing the first sealing part 61 and the second sealing part 62, the entry of external moisture or dust into the drive component 300 and the control component 200 is reduced, minimizing or preventing the impact of external moisture or dust on the first conductive element 12 and the second conductive element 22. The elastic part 63 adjusts the relative positions of the first sealing part 61 and the second sealing part 62 according to the offset or oscillation caused by the first conductive element 12 and the second conductive element 22 during assembly to compensate for tolerances, thus facilitating a better seal between the drive component 300 and the control component 200.

[0081] In some embodiments, the elastic portion 63 includes a first portion 631 and a second portion 632. One end of the first portion 631 is directly or indirectly connected to the first sealing portion 61, one end of the second portion is connected to the other end of the first portion 631, and the other end of the second portion is directly or indirectly connected to the second sealing portion 62. In the axial cross-section of the elastic portion 63, the extending direction of the first portion 631 intersects with the extending direction of the second portion 61, and the extending directions of the second portion and the second sealing portion 62 intersect. One of the first portion 631 and the second portion can swing toward or away from the other. With the above configuration, the first part 631 and the second part 632 can be unfolded or folded relative to each other, which facilitates the adjustment of the relative positions of the first sealing part 61 and the second sealing part 62 in the YZ plane to adapt to the relative position changes between the first conductive element 12 and the second conductive element 22, thereby improving the sealing performance of the sealing element 600. At the same time, compared with setting the elastic part to stretch or compress and shrink itself, the present invention embodiment, by having the first part 631 and the second part 632 unfold or fold relative to each other, facilitates the reduction of stretching or compression on the material of the elastic part 63 itself, and facilitates the improvement of the service life of the elastic part 63.

[0082] Along the radial direction of the seal 600, the elastic portion 63 is disposed around the first sealing portion 61 and the second sealing portion 62, and / or the first sealing portion 61 and the second sealing portion 62 are spaced apart along the axial direction of the seal 600, and at least a portion of the elastic portion 63 is located between the first sealing portion 61 and the second sealing portion 62 along the axial direction of the seal 600.

[0083] Furthermore, the first sealing portion 61 has at least one layer of first sealing protrusions 611, and the second sealing portion 62 has at least one layer of second sealing protrusions 621. The first sealing protrusions 611 are sleeved on the outer periphery of the second housing member 21 and abut against the outer surface of the second housing member 21. The second sealing protrusions 621 are sleeved on the outer periphery of the cover plate 53 and abut against the outer surface of the cover plate 53. This arrangement facilitates the elastic deformation of the first sealing protrusions 611, which improves the sealing performance between the first sealing protrusions 611 and the second housing member 21, and / or the abutment of the second sealing protrusions 621 against the outer surface of the cover plate 53, which further improves the sealing performance between the second sealing protrusions 621 and the cover plate 53.

[0084] like Figure 1 and Figure 17To limit the position of the seal 600, the seal 600 may optionally include a body portion and a mounting protrusion 641. The first sealing portion 61, the second sealing portion 62, and the elastic portion 63 are all located on the body portion, and the mounting protrusion 641 is located on the outer periphery of the body portion and protrudes from the body portion. The cover plate 53 has a mating portion 531, and the mounting protrusion 641 is positioned to limit the position of the seal 600, preventing the seal 600 from rotating and affecting the sealing performance.

[0085] exist Figures 1 to 18 In the illustrated embodiment, the first pin 120 can be connected to the flexible wire 123 first, then the first pin 120 can be assembled to the plug portion 110, and then the second connecting segment 1233 can be connected to the retainer 13 for limiting. The retainer 13 is used to limit the flexible wire 123 to prevent the flexible wire 123 from shifting position. The retainer 13 adopts the form of two support frames being assembled by interlocking.

[0086] like Figure 19 and Figure 20 The diagram shows a partial structural schematic of an electrical connection assembly 100 and a thermal management device 1 according to another embodiment of the present invention. In this embodiment, the first pin 120 and the insertion portion 110 are integrally injection molded parts; the first pin 120 and the first connecting section 1231 are press-fitted and fixed, or the first pin 120 and the first connecting section 1231 are fixed by ultrasonic welding; and / or the second connecting section 1233 and the retainer 13 are integrally injection molded parts.

[0087] In this embodiment of the invention, the retainer 13 is fixedly mounted on the circuit board 30. The first pin 120 and the insertion portion 110 are integrally injection molded parts, and the second connecting section 1233 and the retainer 13 are also integrally injection molded parts. In this embodiment of the invention, the structure of the first conductive element 12 is similar to... Figures 1 to 18 The first conductive element 12 shown has the same or similar structure.

[0088] like Figure 12 , Figure 19 and Figure 20 As shown, the first pin 120 and the flexible conductor 123 are joined by crimping or ultrasonic welding. The flexible conductor 123 must be a high-temperature resistant wire with a polytetrafluoroethylene (PTFE) outer sheath; correspondingly, the retainer 13 and the first housing 11 can be made of polypropylene (PP). The design scheme for the length of the deformable section 1232 of the flexible conductor 123 is as follows... Figures 1 to 18The embodiments shown are the same or similar. The first conductive element 12 is integrally injection molded with the first housing element 11 as an insert. The insertion part 110 and the retainer 13 can also be integrally injection molded. Since a certain space needs to be reserved between the insertion part 110 and the retainer 13 for mold release, the flexible wire 123 needs to be kept in a straight line during injection molding. Figure 19 As shown, after the insertion part 110, the retainer 13 and the first conductive element 12 are injection molded, the flexible wire 123 is bent to form the shape shown in the figure. Figure 20 The deformation segment 1232 is shown. The first housing part 11 after bending has a predetermined gap with the retainer 13 along the first direction XX. The predetermined gap can be greater than or equal to 0.2 mm to prevent the first housing part 11 from being offset or swinging.

[0089] In this embodiment, the first pin 120 protrudes from the insertion portion 110 of the first housing 11. After injection molding and bending of the flexible wire 123, to reduce deviations in the first housing 11 during handling and transportation, such as... Figure 20 As shown, the electrical connection assembly 100 may further include a protective cover 80. The first housing member 11 may include a limiting protrusion 119. The protective cover 80 is sleeved on the outer periphery of the first pin 120, and the protective cover 80 can be installed in conjunction with the limiting protrusion 119 and the retainer 13, so that the protective cover 80, the retainer 13, and the first housing member 11 form a whole to prevent or reduce the positional deviation of the first housing member 11 relative to the retainer 13. The protective cover 80 can be removed before the first terminal 10 and the second terminal 20 are mated.

[0090] It should be noted that the above embodiments only illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be pointed out that those skilled in the art can make several modifications without departing from the concept of this invention, and these modifications all fall within the protection scope of this invention.
