Description

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, a thermal management system comprises multiple functional components, including pump drive components, valve assemblies, and other structures. The thermal management system requires multiple actuators corresponding to these functional components, which in turn drive the components to operate. To power or control each actuator, the thermal management system needs multiple wiring harnesses. Summary of the Invention

[0003] Based on this, the technical solution of this application provides a thermal management device that can reduce the wiring harness structure and improve the stability of electrical signal transmission in the thermal management device.

[0004] On one hand, the technical solution of this application provides a thermal management device, which includes a control component, a drive component, and a fluid assembly. The control component includes a control board, a first pin, and a floating block. The first pin includes a deformable part and a connecting part. The connecting part is electrically connected to the control board through the deformable part. The floating block is limited to the connecting part. The deformable part can drive the floating block to deflect or swing. The drive component includes a motor and a second pin. The motor can drive the fluid assembly to move. One end of the second pin is electrically connected to the motor, and the other end of the second pin is inserted into the floating block and electrically connected to the connecting part.

[0005] According to the thermal management device provided in this application, the control component includes a control board and a first pin, and the drive component includes a motor and a second pin. One end of the second pin is electrically connected to the motor, and the other end of the second pin is inserted into a floating block. The connection portion of the second pin and the first pin is electrically connected. The connection portion of the first pin is electrically connected to the control board of the control component through a deformation portion, enabling the control board to input control electrical signals to the motor through the first pin and the second pin. This facilitates the transmission of electrical signals between the control board and the motor, allowing the control board to control the operation of the motor and facilitates the motor to drive the fluid components. The first pin is electrically connected to the control board. By setting the first pin and the second pin to be electrically connected, the wiring harness structure between the drive component and the control component can be omitted. By setting the first pin to include a connecting part and a deformable part, and setting the connecting part to limit the floating block, the deformable part can drive the floating block to shift or swing. After the deformable part is deformed, it drives the floating block and the connecting part to shift or swing, which is beneficial to adjust the relative position between the connecting part of the first pin and the second pin. It is also beneficial to make up for the tolerance between the first pin and the second pin during the assembly process, and to improve the electrical connection stability between the first pin and the second pin.

[0006] On the other hand, the present application also provides a thermal management device, which includes a control component, a drive component, and a fluid assembly. The control component includes a control board and a first pin, the first pin being electrically connected to the control board. The drive component includes a motor, a second pin, and a floating block. The second pin includes a deformable portion and a connecting portion, the connecting portion being electrically connected to the motor through the deformable portion. The floating block is limited to the connecting portion, the deformable portion being able to drive the floating block to offset or swing, and the motor being able to drive the fluid assembly to move. One end of the first pin is electrically connected to the control board, and the other end of the first pin is inserted into the floating block and electrically connected to the connecting portion.

[0007] According to the thermal management device provided in this application, the control component includes an electrically connected control board and a first pin, and the driving component includes a motor, a second pin, and a floating block. One end of the first pin is electrically connected to the control board, and the other end of the first pin is inserted into the floating block. The connection portion of the first pin and the second pin is electrically connected, and the connection portion of the second pin is electrically connected to the motor through a deformation portion. This allows the control board to input control electrical signals to the motor through the first pin and the second pin, facilitating the transmission of electrical signals between the control board and the motor. This is beneficial for the control board to control the operation of the motor and facilitates the motor to drive the fluid components. Furthermore, the first pin is electrically connected to the control board. By setting the first pin and the second pin to be electrically connected, it is convenient to omit the wiring harness structure between the drive component and the control component. By setting the second pin to include a connecting part and a deformable part, and the connecting part being limited by the floating block, the deformable part can drive the floating block to shift or swing. After the deformable part is deformed, it drives the floating block and the connecting part to shift or swing, which is beneficial to adjust the relative position between the connecting part of the second pin and the first pin. It is also beneficial to compensate for the tolerance between the first pin and the second pin during the assembly process, which is convenient to improve the electrical connection stability between the first pin and the second pin.

[0026] 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.

[0027] 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.

[0028] Based on this, such as Figures 1 to 10As 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 40, a fluid assembly 50, and a drive component 20. The fluid assembly 50 may include at least one of a pump assembly 51 and a valve assembly. Correspondingly, the drive component 20 includes at least one of a pump drive component 24 and a valve drive component 25. The pump drive component 24 drives the pump assembly 51 to rotate to allow fluid flow, and the valve drive component 25 drives the valve assembly to actuate to achieve flow path switching. The pump assembly 51 includes an impeller assembly 511, and the valve assembly includes a valve core and a seal. At least a portion of the fluid assembly 50 may be located within a receiving cavity defined by the flow channel plate assembly 40, or the fluid assembly 50 may be sealed and limited to the flow channel plate assembly 40. The flow channel plate assembly 40 includes a flow channel plate 42, which has at least one of a pump chamber 44 and a valve chamber 45. At least a portion of the pump assembly 51 may be located in the pump chamber 44, and at least a portion of the valve assembly may be located in the valve chamber 45. The flow channel plate assembly 40 has a coolant passage 41 that connects the pump assembly 51 and the valve assembly, facilitating fluid interaction between them. This arrangement reduces or eliminates the piping between the pump assembly 51 and the valve assembly, improving the integration of the thermal management device 1.

[0029] 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 51 and valve assembly increases, and the number of corresponding pump drive component 24 and valve drive component 25 gradually increases. In order to control the pump drive component 24 and valve drive component 25, multiple wiring harness structures need to be set up to be electrically connected to the pump drive component 24 and valve drive component 25 respectively, which occupies a large space and has a high cost.

[0030] Please refer to further information. Figures 1 to 7 To address the aforementioned issues, in this embodiment of the invention, the thermal management device 1 further includes a control component 10. The control component 10 includes a control board 11, which is electrically connected to at least two drive components 20. In this embodiment, the control board 11 can be a printed circuit board assembly (PCBA). All drive components 20 corresponding to all fluid components 50 of the thermal management device 1 can be electrically connected to the same control board 11, facilitating the control of the motor 21 in the drive component 20 through a single control board 11, thereby improving the domain control integration of the thermal management device 1.

[0031] In some embodiments, the number of drive components 20 is at least two, and one drive component 20 drives the corresponding fluid component 50 to operate. The control component 10 includes at least two sets of first pins 12, at least two floating blocks 13, and a control board 11. Each set of first pins 12 includes multiple first pins 12. One set of first pins 12 is electrically connected to the second pin 22 of a corresponding drive component 20. At least two sets of first pins 12 are electrically connected to the control board 11. The second pins 22 in at least two drive components 20 are electrically connected to the corresponding first pins 12, which facilitates improving the domain control integration of the thermal management device 1.

[0032] In a specific implementation, the control component 10 may include at least two sets of first pin groups, each set of first pin groups including multiple first pins 12. Each set of first pin groups is electrically connected to a corresponding second pin in a drive component 20, allowing the control board 11 to control the operation of a motor in a drive component 20 through a set of first pin groups. For example, in this embodiment, the first pin group corresponding to the pump drive component 24 includes four first pins 12, and the pump drive component 24 includes four second pins 22. The first pins 12 and the second pins 22 can correspond one-to-one and be electrically connected. Each first pin 12 is electrically connected to the control board 11, and each drive component 20 includes a motor 21 and a second pin 22 that are electrically connected to each other. The second pin 22 is abutted, in contact with, or soldered to the corresponding first pin 12 to achieve electrical connection between them. With the above configuration, a single control board 11 can control the motors 21 in at least two drive components 20, and the motors are electrically connected via the first pin 12 and the second pin 22. This reduces the wiring harness structure between the control component 10 and the drive component 20, and also reduces the need for a separate circuit board for each drive component 20, 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.

[0033] like Figures 2 to 9As shown, at least a portion of the first pin 12 is disposed in the control component 10, and the first pin 12 is electrically connected to the control board 11. The control component 10 includes a control housing with a control cavity 401. The control board 11 is located in the control cavity 401, and the control board 11 can be limitedly connected to the control housing. Optionally, the control board 11 and the control housing can be fixed together as a whole by hot riveting or bolting. At least a portion of the second pin 22 is disposed in the drive component 20. One of the second pin 22 and the first pin 12 is inserted into the other, and the first pin 12 and the second pin 22 are in contact or abut against each other to realize the electrical connection between the first pin 12 and the second pin 22, thereby enabling the current and electrical signals of the control board 11 to be transmitted to the motor 21 via the first pin 12 and the second pin 22.

[0034] Since the first pin 12 and the second pin 22 are respectively disposed in two components, and since the manufacturing of the first pin 12 itself and its assembly with the control board 11, or the assembly of the PCBA board and the control housing, are prone to tolerances, the first pin 12 has a first tolerance. The first tolerance is the tolerance of the plane perpendicular to the extension direction of the first pin 12, that is, the first tolerance is the tolerance of the plane perpendicular to the extension direction of the first pin 12. Figure 4 The tolerance in the XY plane. Similarly, the second pin 22 itself is prone to a second tolerance during manufacturing and assembly, that is, the second tolerance is an additional tolerance. Figure 4 The tolerance in the XY plane causes the first pin 12 and the second pin 22 to have a third tolerance during assembly, which 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.

[0035] To improve the above issues, please refer to the following: Figures 1 to 9 In some embodiments, the control component further includes a floating block 13. The first pin 12 includes a deformable portion 122 and a connecting portion 121. The connecting portion 121 is electrically connected to the control board 11 through the deformable portion 122. The floating block 13 is limited to the connecting portion 121, and the deformable portion 122 can drive the floating block 13 to move in a certain position. Figure 4The XY plane offset or oscillation shown in the diagram is driven by a motor 21 and a second pin 22. The motor 21 drives the fluid assembly 50 to move. One end of the second pin 22 is electrically connected to the motor 21. Specifically, one end of the second pin 22 can be electrically connected to the coil assembly 211 in the motor 21. The other end of the second pin 22 is inserted into the floating block 13 and electrically connected to the connecting part 121. With the above arrangement, the control board 11 can input control electrical signals to the motor 21 through the first pin 12 and the second pin 22, which facilitates the transmission of electrical signals between the control board 11 and the motor 21. This is beneficial for the control board 11 to control the operation of the motor 21 and facilitates the motor 21 to drive the fluid assembly 50 to move. The first pin 12 is electrically connected to the control board 11. By setting the first pin 12 and the second pin 22 to be electrically connected, the wiring harness structure between the drive component 20 and the control component 10 can be omitted. By setting the first pin 12 to include a connecting part 121 and a deformable part 122, and limiting the connecting part 121 to the floating block 13, the deformable part 122 can drive the floating block 13 to shift or swing. After the deformable part 122 deforms, it drives the floating block 13 and the connecting part 121 to shift or swing. This is beneficial for adjusting the relative position between the connecting part 121 of the first pin 12 and the second pin 22, and for compensating for the tolerance between the first pin 12 and the second pin 22 during the assembly process. This also helps to improve the electrical connection stability between the first pin 12 and the second pin 22.

[0036] Optionally, the constituent materials of the floating block 13 may include plastics. For example, the constituent materials of the floating block 13 may include, but are not limited to, at least one of thermoplastic resin (PA66) and polypropylene (PP), or glass fiber material may be added to the constituent materials of the floating block 13.

[0037] In some embodiments, combined with Figure 4 , Figure 6 and Figure 7 As shown, along the height direction of floating block 13, i.e., attached Figure 4 In the ZZ direction, the control plate 11 and the floating block 13 are arranged side by side. The deformation part 122 includes at least two sub-parts 120. There is an included angle between two adjacent sub-parts 120. Along the height direction perpendicular to the floating block 13, one of the two adjacent sub-parts 120 can swing towards or away from the other. The deformation part 122 can deform. At this time, the included angle between the two adjacent sub-parts 120 is adjusted so that the relative position between the floating block 13 and the control plate 11 is adjusted, so that the connection part 121 of the floating block 13 and the first pin 12 floats in the XY plane, which makes it easier to compensate for the tolerance between the first pin 12 and the second pin 22 and realize a stable electrical connection between the connection part 121 and the second pin 22.

[0038] Please see Figures 4 to 7 In some embodiments, the deformable portion 122 includes a first sub-portion 123 and a second sub-portion 124. The first sub-portion 123 is connected to the control board 11, one end of the second sub-portion 124 is connected to the first sub-portion 123, and the other end of the second sub-portion 124 is connected to the connecting portion 121. Both the first sub-portion 123 and the second sub-portion 124 have gaps with the floating block 13, facilitating space for adjusting the relative position between them. The extending direction of the first sub-portion 123 intersects with the extending direction of the second sub-portion 124, and the extending direction of the connecting portion 121 also intersects with the extending direction of the second sub-portion 124. The second sub-portion 124 can swing towards or away from the connecting portion 121. This configuration facilitates increasing the floating amount of the floating block 13 and the connecting portion 121 in the XY plane, thereby compensating for the tolerance between the first pin 12 and the second pin 22 and achieving a stable electrical connection between the first pin 12 and the second pin 22.

[0039] In some embodiments, the first sub-part 123 and the second sub-part 124 have a rounded transition, which helps to reduce stress concentration between the first sub-part 123 and the second sub-part 124 and facilitates the manufacture of the first pin 12. Since the deformable part 122 can offset or swing in the XY plane, in order to make the stress of the second sub-part 124 offset or swing relative to the first sub-part 123 in each direction the same or similar, in some embodiments, at least one of the cross-sections of the first sub-part 123 and the second sub-part 124 includes a circle or a regular polygon, which is beneficial for the floating block 13 to offset or swing in each direction of the XY plane, and is beneficial for better realizing the electrical connection between the first pin 12 and the second pin 22.

[0040] In this embodiment of the invention, each first pin 12 of a set of first pin groups is positioned relative to a floating block 13. To increase the stability of the positioning connection between the first pin 12 and the floating block 13, at least a portion of the connecting part 121 includes a plate-like structure, which facilitates increasing the contact area with the floating block. The direction in which the connecting part 121 faces the second pin 22 is defined as the first direction, and this first direction is related to the attached... Figure 5 The XX directions are parallel or coincident. Along the first direction, the thickness of the connecting part 121 is defined as H1, and along the direction perpendicular to the first direction, the width of the connecting part 121 is L1, where H1 < L1. At this time, the connecting part 121 facing the second pin 22 has a flat plate structure, which facilitates the deformation of the connecting part 121 along the first direction, so that there is a large contact force between the connecting part 121 and the second pin 22.

[0041] like Figure 7As shown, the first sub-part 123 and the second sub-part 124 both have circular cross-sections, and there is an arc transition between the first sub-part 123 and the second sub-part 124. There is also an arc transition between the second sub-part 124 and the connecting part 121, and there is a transition section between the second sub-part 124 and the connecting part 121, so that the circular cross-section of the second sub-part 124 transitions into a plate-shaped connecting part 121 with a polygonal cross-section through the transition section. This arrangement facilitates stable deformation of the deformable part 122 and facilitates the connection between the connecting part 121 and the floating block 13 and the second pin 22.

[0042] Furthermore, such as Figures 2 to 9 As shown, when the drive component 20 includes the pump drive component 24, the pump drive component 24 includes the drive housing 23, and the drive component 20 also includes the terminal housing portion 221. The terminal housing portion 221 and the second pin 22 can be injection molded into an integral structure. The terminal housing portion 221 can protrude from the drive housing 23. In order to reduce the space occupied by the thermal management device 1 and the pump drive component 24, the space between the terminal housing portion 221 and the second pin 22 and the side wall of the drive housing 23 is small. In this paper, the side wall of the drive housing 23 is the wall surrounding the axis of the pump drive component 24.

[0043] Based on this, in some embodiments, the outer peripheral surface of the floating block 13 includes a first outer surface 131 and a second outer surface 132. The first outer surface 131 faces the sidewall of the drive housing 23, and the first outer surface 131 and the second outer surface 132 intersect. The connecting portion 121 includes a third sub-portion 125 and a fourth sub-portion 126. One end of the third sub-portion 125 is connected to the second sub-portion 124, and the other end of the third sub-portion 125 is connected to the fourth sub-portion 126. The third sub-portion 125 is located on the side of the first outer surface 131, and the fourth sub-portion 126 is located on the inner surface side of the floating block 13. The fourth sub-portion 126 is electrically connected to the second pin 22. At least a portion of the projection of the deformable portion 122 on the side of the second outer surface 132 is located within the second outer surface 132, or the projection of the deformable portion 122 onto the extension surface of the second outer surface 132 is disposed adjacent to the second outer surface 132. With the above arrangement, compared to setting the deformable part on the side of the connecting part away from the first outer surface 131, it is easier to reduce the space occupied by the first pin 12 in the direction toward the side wall of the drive housing 23, thereby making it easier to reduce the space between the first pin 12 and the side wall surface of the drive housing 23.

[0044] To facilitate a secure electrical connection between the fourth sub-part 126 and the second pin 22, in some embodiments, at least a portion of the fourth sub-part 126 has a gap with the inner surface of the floating block 13, providing space for the abutment deformation of the fourth sub-part 126 when the second pin 22 and the fourth sub-part 126 are assembled and abutted.

[0045] In some embodiments, the drive component 20 further includes a terminal housing portion 221, with the second pin 22 fixedly connected to the terminal housing portion 221 and exposed on the outer surface of the terminal housing portion 221. The terminal housing portion 221 has a first chamfer, which can be a right-angle structure or a rounded corner structure. The first chamfer is located at the end of the terminal housing portion 221, and its width is defined as D1. The floating block 13 includes a second chamfer, which extends from the end face of the floating block 13 toward the drive component 20 toward the interior of the floating block 13, and its width is defined as D2. The tolerance between the first pin 12 and the second pin 22 assembly is D3, where D1 + D2 ≥ D3. This configuration facilitates the guiding adjustment of the terminal housing portion 221 during the assembly and insertion of the floating block 13 via the first and second chamfers, thereby improving the assembly efficiency and accuracy of the first pin 12 and the second pin 22.

[0046] Please refer to further information. Figures 5 to 9 In some embodiments, the floating block 13 has a limiting groove 133 extending from the inner surface of the floating block 13 toward the interior of the floating block 13, at least a portion of the fourth sub-part 126 being located within the limiting groove 133, and defining a sidewall surface of the limiting groove 133 abutting against the fourth sub-part 126. Figure 5 In this assembly, the fourth sub-part 126 can abut against the side wall of the limiting groove 133, and at least a portion of the fourth sub-part 126 has a gap with the bottom wall of the limiting groove 133, providing space for deformation when the fourth sub-part 126 abuts against the second pin 22. Optionally, the fourth sub-part 126 may include a guide bevel 1261 and a contact portion 1262, with an angle between the contact portion 1262 and the guide bevel 1261. The guide bevel 1261 can guide the second pin 22 during assembly, facilitating abutment between the fourth sub-part 126 and the second pin 22.

[0047] Furthermore, to support the first pin 12, in some embodiments, in conjunction with Figure 5 , Figure 8 and Figure 9 As shown, the floating block 13 also includes a support surface 134, which is located further away from the drive component 20 than the end face of the floating block 13 facing the drive component 20. The connecting portion 121 abuts against the support surface 134. Optionally, the support surface 134 can be an arc surface to facilitate support for the connecting portion 121 and facilitate abutment between the fourth sub-part 126 and the second pin 22.

[0048] To limit the position of floating block 13, such as Figure 8 and Figure 9As shown, the floating block 13 also includes a main body 135 and at least two limiting blocks 136. The connecting part 121 is fixedly connected to the main body 135 or is an integral structure. The at least two limiting blocks 136 are evenly arranged along the outer periphery of the main body 135. The limiting blocks 136 are located between the main body 135 and the control plate 11, and at least a portion of the limiting blocks 136 can abut against the control plate 11. With the above configuration, when the second pin 22 is inserted into the floating block 13 and abuts against the first pin 12 for electrical connection, the position of the floating block 13 can be limited by the limiting blocks 136, thereby improving the structural stability of the domain control part of the thermal management device.

[0049] Furthermore, the main body 135 of the floating block 13 also includes a boss 137 and a connector 138. The boss 137 protrudes from the outer peripheral surface of the connector 138. At least a portion of the second chamfer is located on the boss 137. At least a portion of the connecting portion 121 is limitedly connected to the connector 138. A portion of the second pin 22 is inserted into the connector 138. Along the height direction of the thermal management device 1, the deformation portion 122 is located on the side of the boss 137 near the control plate 11, and there is a gap between the deformation portion 122 and the boss 137. With the above arrangement, it is convenient to increase the width of the second chamfer and to reduce the space occupied by the floating block 13. Moreover, the gap between the deformation portion 122 and the boss 137 facilitates the adjustment of the position of the deformation portion 122, making it easier to realize the floating position of the floating block 13.

[0050] Please refer to further information. Figure 1 In some embodiments, the flow channel plate assembly 40 includes a first flow channel plate 421, which defines a portion of the wall of the coolant passage 41. The control housing of the thermal management device 1 includes a cover plate 43, which is disposed adjacent to the drive component 20. The cover plate 43 and the first flow channel plate 421 are sealed to define a control cavity 401. The control plate 11, the first pin 12, and the floating block 13 are located in the control cavity 401. In this case, the first flow channel plate 421 is reused as part of the control housing, which helps to reduce the number of parts in the thermal management device 1. Furthermore, the distance between the control cavity 401 and the drive component 20 is relatively short, which facilitates the design of the control housing. Figures 1 to 9 The first pin 12 shown in the embodiment can cause the deformation part 122 to produce a large deformation, which makes it easier for the floating block 13 to have a large floating amount, thereby compensating for the tolerance between the first pin 12 and the second pin 22.

[0051] Please see his 4th to Figure 6In some embodiments, the cover plate 43 includes a plate portion 431 and a first protrusion 432. The first protrusion 432 protrudes from the plate portion 431 and is located in the control cavity 401. The plate portion 431 has a through hole through which the second pin 22 passes and is inserted into the floating block 13. The first protrusion 432 has an annular structure and is arranged around the outer periphery of the floating block 13. The first protrusion 432 has a third chamfer. The tolerance between the first pin 12 and the second pin 22 assembly is defined as D3, and the width of the third chamfer is D4, where D4 ≥ D3. With the above configuration, before the drive component 20 and the control component 10 are assembled, the position of the floating block 13 can be limited by the first protrusion 432, which facilitates the insertion of the second pin 22 in the drive component 20 into the floating block 13.

[0052] Furthermore, the projection of the floating block 13 onto the plate portion 431 at least partially overlaps with the plate portion 431. This arrangement allows the plate portion 431 to limit the movement of the floating block 13 when the driving member 20 disengages from it. Figure 5 As shown, the lower limit position of the floating block 13 is limited by the control plate 11, and the upper limit position of the floating block 13 is limited by the plate part 431.

[0053] To seal the drive component 20 and the control component 10, in some embodiments, the cover plate 43 further includes a second protrusion 433. The second protrusion 433 protrudes from the plate portion 431 in a direction away from the control cavity 401. The second protrusion 433 has an annular structure. The thermal management device 1 also includes a seal 30, which is sealed between the second protrusion 433 and the drive component 20. This arrangement facilitates sealing of the first pin 12 and the second pin 22, reducing or preventing damage to the first pin 12 and the second pin 22 from external moisture or dust.

[0054] Please see Figure 4 and Figure 5In the axial section of the seal 30, the seal 30 includes a first sealing portion 31 and a second sealing portion 32. The extending directions of the first sealing portion 31 and the second sealing portion 32 intersect. The driving component 20 includes a driving housing 23. The first sealing portion 31 is sealed to the driving housing 23. The first end of the second sealing portion 32 is connected to the first sealing portion 31, and the second end of the second sealing portion 32 is sealed to the second protrusion 433. The first sealing portion 31 can tilt and swing towards or away from the second sealing portion 32. With the above configuration, it is convenient to adjust the relative positions of the first sealing portion 31 and the second sealing portion 32 in the XY plane to adapt to the relative position changes between the first pin 12 and the second pin 22, thereby improving the sealing performance of the seal 30. At the same time, compared with setting the seal to be stretched or compressed, the present invention embodiment, by having the first sealing portion 31 and the second sealing portion 32 unfold or fold towards each other, facilitates the reduction of stretching or compression on the material of the seal 30 itself, and facilitates the improvement of the service life of the seal 30.

[0055] Furthermore, the thickness of the second sealing portion 32 near its second end is less than the thickness of the second sealing portion 32 near its first end. This arrangement facilitates the contact between the second sealing portion 32 and the second protrusion 433, improving the sealing performance of the seal 30. Optionally, the first sealing portion 31 can be inserted into the limiting groove of the drive housing 23.

[0056] Combining the above possible implementation methods, the first pin 12 and the floating block 13 can form a floating female end. At this time, the first pin 12 can be a female pin 62, and the second pin 22 can be a male pin 61. The male pin 61 is inserted into the floating female end, thus realizing the electrical connection between the first pin 12 and the second pin 22.

[0057] Further, please refer to Figures 10 to 16 This illustrates a thermal management device according to other embodiments of the present invention. Specifically, in this embodiment, the flow channel plate assembly 40 includes a plurality of flow channel plates 42, which define a portion of the wall of the coolant passage 41. Along the height direction of the thermal management device 1, at least one flow channel plate 42 is provided between the control plate 11 and the drive component 20. At this time, the distance between the control plate 11 and the drive component 20 is relatively large, and the length of the first pin 12 is relatively long. At this time, the first pin 12 is a straight pin or the first pin 12 includes a bent portion. By setting the first pin 12 to be longer, the first pin 12 can have a larger floating amount, which is convenient to compensate for the tolerance between the first pin 12 and the second pin 22.

[0058] In some embodiments, one of the first pin 12 and the second pin 22 is a male pin 61 and the other is a female pin 62; or one of the first pin 12 and the second pin 22 is a first male pin 63 and the other includes a second male pin 64 and a female adapter terminal 65, wherein the second male pin 64 is electrically connected to the first male pin 63 through the female adapter terminal 65.

[0059] Optionally, such as Figure 12 and Figure 13 As shown, the first pin 12 is a male pin 61, and the second pin 22 is a female pin 62. One end of the first pin 12 is electrically connected to the control board via a limiting seat 14, and the floating block 13 is positioned near the other end of the first pin 12. Optionally, the first pin 12, the floating block 13, and the limiting seat 14 can be integrally injection molded into a single first pin terminal. Then, the first pin terminal is fixed to the control board 11 via the limiting seat 14 using a heat-riveting method. Afterward, the first pin 12 is soldered to the control board. The first pin terminal is assembled into position by the cooperation of the floating block 13 with the guide structure on the flow channel plate 42. After assembly, as shown... Figure 12 The floating block 13 shown has a gap with the wall of the corresponding flow channel plate 42 surrounding the outer periphery of the floating block 13. The floating block can move within the gap range, which facilitates the compensation of the tolerance between the first pin 12 and the second pin 22.

[0060] like Figure 13 As shown, the drive component 20 has a female terminal, which can be integrally injection molded with the main body of the drive component 20. The female terminal may include a second pin 22 (female pin), a female terminal shell 221, and a sealing ring 26. The second pin 22 is electrically connected to the motor 21 in the drive component 20, or the second pin 22 is electrically connected to the motor 21 through the circuit board 251 in the drive component 20. When the drive component 20 is installed toward the flow channel plate assembly 40, the second pin 22 cooperates with the guide block of the male terminal through its own guide angle. The gap between the floating block 13 and the wall of the flow channel plate 42 and the deformation of the first pin 12 itself are used to compensate for the tolerance between the first pin 12 and the second pin 22, thereby completing the connection between the first pin 12 and the second pin 22, and sealing the first pin 12 and the second pin 22 by the sealing ring 26.

[0061] Or such as Figures 14 to 16 As shown, the first pin 12 includes a first male pin 63 and a female adapter terminal 65, and the second pin is a second male pin 64. The second male pin 64 is electrically connected to the first male pin 63 through the female adapter terminal 65, wherein the female adapter terminal 65 includes a female pin connecting block and an adapter pin 651. The connection method of the first pin 12 and the second pin 22 is similar to... Figures 11 to 13 The connection methods are the same or similar, so they will not be described in detail again.

[0062] On the other hand, embodiments of the present invention also provide a thermal management device 1, which includes a control component 10, a drive component 20, and a fluid assembly 50. The control component 10 includes a control board 11 and a first pin 12, which is electrically connected to the control board 11. The drive component 20 includes a motor 21, a second pin 22, and a floating block 13. The second pin 22 includes a deformation part 122 and a connecting part 121, which is electrically connected to the motor 21 through the deformation part 122. The floating block 13 is limited to the connecting part 121. The deformation part 122 can drive the floating block 13 to shift or swing. The motor 21 can drive the fluid assembly 50 to move. One end of the first pin 12 is electrically connected to the control board 11, and the other end of the first pin 12 is inserted into the floating block 13 and electrically connected to the connecting part 121. The structure of the floating block 13 and the connection relationship between the floating block 13 and the second pin 22 in the embodiments of the present invention are similar to those in the present invention. Figures 1 to 9 The structure of the floating block 13 and its connection with the first pin 12 shown in the figure are the same as or similar, and will not be described again. The structure of the second pin 22 in this embodiment of the invention is the same as... Figures 1 to 9 The structure of the first pin 12 shown is the same as or similar to that shown in the figure, and will not be described again. Through the above arrangement, the control board 11 can input control electrical signals to the motor 21 through the first pin 12 and the second pin 22, facilitating the transmission of electrical signals between the control board 11 and the motor 21. This is beneficial for the control board 11 to control the operation of the motor 21, making it easier for the motor 21 to drive the fluid assembly 50. The first pin 12 is electrically connected to the control board 11. By setting the first pin 12 and the second pin 22 to be electrically connected, the wiring harness structure between the drive component and the control component can be omitted. The second pin 22 includes... The connecting part 121 and the deformable part 122 are positioned to limit the floating block 13, so that the deformable part 122 can drive the floating block 13 to shift or swing. After the deformable part 122 deforms, it drives the floating block 13 and the connecting part 121 to shift or swing. This is beneficial for adjusting the relative position between the connecting part of the second pin 22 and the first pin 12, and for compensating for the tolerance between the first pin 12 and the second pin 22 during the assembly process. This also helps to improve the electrical connection stability between the first pin 12 and the second pin 22.

[0063] It should be noted that the above-described embodiments only illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, 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.
