[0064] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0065] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0066] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0067] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0068] As people's living standards continue to improve, vehicles have become widely used as a means of transportation. Vehicles include multiple electrical appliances, such as the instrument panel, head unit, lights, power seats, audio equipment, and steering gear. They also include thermal management actuators, such as water pumps, flow valves, fan motors, and air conditioning compressors. Currently, vehicles typically use batteries to provide power, which is distributed to these appliances via low-voltage power distribution modules. Thermal management modules are also required to control and drive these thermal management actuators.

[0069] In related technologies, batteries, low-voltage power distribution modules and thermal management modules are usually distributed in different positions of the vehicle. This not only requires separate installation structures for the batteries, low-voltage power distribution modules and thermal management modules, but also requires separate safety distances to be reserved for the batteries, low-voltage power distribution modules and thermal management modules to reduce the risk of contact between the batteries, low-voltage power distribution modules and thermal management modules and other components, resulting in a large total space occupied by the batteries, low-voltage power distribution modules and thermal management modules. In addition, in order to protect the batteries, low-voltage power distribution modules and thermal management modules, it is usually necessary to separately configure housings for the batteries, low-voltage power distribution modules and thermal management modules, which increases the volume of the batteries, the volume of the low-voltage power distribution modules and the volume of the thermal management modules, resulting in a further increase in the total space occupied by the batteries, low-voltage power distribution modules and thermal management modules, thereby significantly reducing the space utilization of the vehicle.

[0070] In order to improve the space utilization of the vehicle, the battery, low-voltage power distribution module and thermal management module of the control device provided in the embodiment of the present application are housed in a box, so that the battery, low-voltage power distribution module and thermal management module are integrated into a whole. Compared with the dispersed arrangement of the battery, low-voltage power distribution module and thermal management module, not only is there no need to separately allocate assembly space for the battery, low-voltage power distribution module and thermal management module, which effectively saves the assembly space of the control device, but there is also no need to separately configure a shell for the battery, low-voltage power distribution module and thermal management module, which effectively reduces the volume of the control device and makes the overall structure of the control device more compact, thereby effectively improving the space utilization of the vehicle using the above-mentioned control device.

[0071] The control device provided in the embodiments of the present application can be applied to electrical equipment. The control device can be used to distribute electrical energy to various electrical appliances in the electrical equipment, and can also be used to drive and control various thermal management actuators in the electrical equipment.

The fixing structure can be, but is not limited to, a fastening structure, a snap-fit ​​structure, an adhesive structure, etc.

[0085] In some embodiments, when vehicle 1000 is a new energy vehicle, vehicle 1000 includes a power battery, the power battery includes a liquid cooling device, the thermal management actuator in the liquid cooling device is a water pump, and the thermal management circuit is electrically connected to the water pump to control the operation of the water pump, thereby controlling the flow of coolant in the liquid cooling device, thereby achieving the purpose of regulating the temperature of the power battery.

[0086] In other embodiments, vehicle 1000 includes an engine and a cooling fan, the cooling fan is used to dissipate heat from the engine, the thermal management actuator in the cooling fan is a motor, and the thermal management circuit is electrically connected to the motor to control the operation of the motor, thereby controlling the speed of the cooling fan, and thus achieving the purpose of regulating the temperature of the engine.

[0087] In some other embodiments, vehicle 1000 includes a liquid cooling system, and the thermal management actuator in the liquid cooling system is a flow valve, which is arranged in a cooling pipe in the liquid cooling system. The thermal management circuit is electrically connected to the flow valve to change the flow rate of coolant in the cooling pipe by changing the opening of the flow valve, thereby achieving the purpose of regulating the temperature of the engine and power battery.

[0088] In some further embodiments, the vehicle 1000 includes an air conditioner, the thermal management actuator in the air conditioner is a compressor, and the thermal management circuit is electrically connected to the compressor to control the operation of the compressor, thereby achieving the purpose of regulating the cooling capacity or heating capacity of the air conditioner.

[0089] In some embodiments, the thermal management module 140 can also be electrically connected to the low-voltage power distribution module 130 , and part of the electrical energy provided by the battery 120 is transmitted to the thermal management module 140 through the low-voltage power distribution module 130 to power the thermal management module 140 .

[0090] The control device 100 provided in the embodiment of the present application accommodates the battery 120, the low-voltage power distribution module 130 and the thermal management module 140 in the box 110, so that the battery 120, the low-voltage power distribution module 130 and the thermal management module 140 are integrated into a whole. Compared with the dispersed arrangement of the battery 120, the low-voltage power distribution module 130 and the thermal management module 140, not only is there no need to separately allocate assembly space for the battery 120, the low-voltage power distribution module 130 and the thermal management module 140, which effectively saves the assembly space of the control device 100, but also there is no need to separately configure a shell for the battery 120, the low-voltage power distribution module 130 and the thermal management module 140, which effectively reduces the volume of the control device 100, making the overall structure of the control device 100 more compact, thereby effectively improving the space utilization rate of the electrical equipment using the above-mentioned control device 100.

[0091] In some embodiments of the present application, please refer to Figure 3, the control device 100 also includes a cooling module 150, which is arranged between the low-voltage power distribution module 130 and the thermal management module 140, and the low-voltage power distribution module 130 and the thermal management module 140 are thermally connected to the cooling module 150.

[0092] The cooling module 150 is a component used to absorb the heat generated by the operation of the low-voltage power distribution module 130 and the thermal management module 140. The low-voltage power distribution module 130, the thermal management module 140, and the cooling module 150 are thermally conductively connected, which means that the low-voltage power distribution module 130, the thermal management module 140, and the cooling module 150 are in contact with each other, and the heat generated by the operation of the low-voltage power distribution module 130 can be transferred to the cooling module 150 through the contact portion between the low-voltage power distribution module 130 and the cooling module 150. Similarly, the heat generated by the operation of the thermal management module 140 can be transferred to the cooling module 150 through the contact portion between the thermal management module 140 and the cooling module 150. Of course, in other embodiments, the cooling module 150 can also be thermally conductively connected to other components of the control device 100 to cool the components. For example, the cooling module 150 can also be thermally conductively connected to the battery 120. The cooling module 150 can be, but is not limited to, a liquid cooling module, an air cooling module, a metal thermal conductive module, etc. The cooling module 150 may be fixed in the box body 110 by a fixing structure, and the fixing structure may be, but is not limited to, a fastening structure, a snap-fit ​​structure, an adhesive structure, and the like.

[0093] By adopting the above technical solution, the low-voltage distribution module 130 and the thermal management module 140 can share a cooling module 150, effectively reducing the number of cooling modules 150 and further reducing the volume of the control device 100, thereby further improving the space utilization of the vehicle 1000 using the above control device 100.

[0094] In some embodiments of the present application, referring to FIG4 , the cooling module 150 includes a liquid cooling plate 151 , a liquid inlet connector 152 , and a liquid outlet connector 153 . A cooling channel (not shown) is provided inside the liquid cooling plate 151 . The low-voltage power distribution module 130 and the thermal management module 140 are thermally connected to the liquid cooling plate 151 . The liquid inlet connector 152 is connected to the liquid inlet end of the cooling channel, and the liquid outlet connector 153 is connected to the liquid outlet end of the cooling channel.

[0095] In other words, in this embodiment, the cooling module 150 is a liquid cooling module.

[0096] Liquid cooling plate 151 is the main component of cooling module 150. It can be made of, but is not limited to, aluminum, aluminum alloy, copper, iron, stainless steel, etc. The cooling channel of liquid cooling plate 151 provides space for the flow of a cooling medium, which can be, but is not limited to, cooling water, cooling oil, etc.

[0097] The liquid inlet connector 152 is used to connect to an external liquid supply line and deliver cooling medium to the interior of the cooling channel. The liquid inlet connector 152 and the liquid cooling plate 151 can be integrally formed. Alternatively, the liquid inlet connector 152 and the liquid cooling plate 151 can be connected separately, for example, by welding them together.

[0098] Liquid outlet connector 153 is a component used to connect to an external drain line and output the cooling medium to the outside of the cooling channel. Liquid outlet connector 153 and liquid cooling plate 151 can be integrally formed components, that is, the liquid outlet connector 153 and liquid cooling plate 151 are integrally formed. Liquid outlet connector 153 and liquid cooling plate 151 can also be connected separately, for example, the liquid outlet connector 153 and liquid cooling plate 151 can be welded together to form a single piece.

[0099] By adopting the above technical solution, the efficiency of the cooling module 150 in cooling the low-voltage power distribution module 130 and the thermal management module 140 is effectively improved, thereby effectively improving the reliability of the control device 100.

[0100] In some embodiments of the present application, please refer to Figures 3 to 5. The side wall of the box body 110 is provided with a first bayonet 111, and the inner edge of the first bayonet 111 is provided with a first sealing groove 114. The liquid inlet connector 152 includes a first sealing portion 1521 arranged in the first bayonet 111, and the outer peripheral side of the first sealing portion 1521 is convexly provided with a first rib 15211, and the first rib 15211 is inserted into the first sealing groove 114.

[0101] The first bayonet 111 is used to provide a mounting space for the liquid inlet connector 152. The shape of the first bayonet 111 can be, but is not limited to, circular, semicircular, square, trapezoidal, triangular, etc. The inner edge of the first bayonet 111 refers to the portion enclosing the inner space of the first bayonet 111.

[0102] The first sealing portion 1521 is used to seal the first bayonet 111. The outer contour of the first sealing portion 1521 is adapted to the shape of the first bayonet 111. For example, if the first bayonet 111 is semicircular, the outer contour of the first sealing portion 1521 is also semicircular. In some embodiments, the liquid inlet connector 152 may further include a first connecting portion 1522 and a second connecting portion 1523. The first sealing portion 1521 is connected between the first connecting portion 1522 and the second connecting portion 1523. The first connecting portion 1522 is connected to the external liquid supply pipeline, and the second connecting portion 1523 is connected to the liquid cooling plate 151.

[0103] In some embodiments, the first bayonet 111 is recessed in the open end of the box body 110. In other words, the first bayonet 111 passes through the open end of the box body 110 to form a first notch. This means that the first bayonet 111 can connect the internal environment of the box body 110 with the external environment along the thickness direction of the side wall of the box body 110 (the Y direction as shown in FIG. 5 ). The first bayonet 111 can also connect the external environment of the box body 110 through the first notch. A first sealing groove 114 is recessed in the inner edge of the first bayonet 111. The first sealing groove 114 extends along the length of the inner edge of the first bayonet 111 and passes through both ends of the inner edge of the first bayonet 111. The first sealing portion 1521 can enter the first bayonet 111 through the first notch, and at the same time the first rib 15211 enters the first sealing groove 114 until the first sealing portion 1521 is completely inserted into the first bayonet 111. At this time, the first rib 15211 cooperates with the first sealing groove 114 to seal the gap between the outer peripheral side of the first sealing portion 1521 and the inner edge of the first bayonet 111.

[0104] In other embodiments, the first bayonet 111 passes through the sidewall of the box body 110 but does not pass through the open end of the box body 110. In other words, the first bayonet 111 can only connect the internal environment of the box body 110 with the external environment along the thickness direction of the sidewall of the box body 110. The first sealing groove 114 is recessed in the inner edge of the first bayonet 111 and extends along the length direction of the inner edge of the first bayonet 111 to form a closed loop structure. The first rib 15211 forms a closed loop structure surrounding the central axis of the liquid inlet connector 152. The outer diameter of the first rib 15211 is larger than the inner diameter of the first retaining opening 111. As the first sealing portion 1521 passes through the first retaining opening 111, the first rib 15211 is squeezed by the inner edge of the first retaining opening 111 until the first rib 15211 enters the first sealing groove 114. At this point, the first rib 15211 cooperates with the first sealing groove 114 to seal the gap between the outer periphery of the first sealing portion 1521 and the inner edge of the first retaining opening 111. In this embodiment, to facilitate entry of the first rib 15211 into the first sealing groove 114, the first rib 15211 can be made of a flexible material, such as, but not limited to, rubber or silicone. In other embodiments, the first sealing portion 1521 and the first rib 15211 can be integrally formed of a flexible material.

[0105] In some embodiments, in order to further improve the sealing performance of the control device 100 , the first sealing groove 114 may be filled with sealant.

[0106] By adopting the above technical solution, the liquid inlet connector 152 can be passed through the first bayonet 111 and close the first bayonet 111, thereby effectively improving the sealing performance of the control device 100. Moreover, there is no need to set up additional sealing parts to seal the first bayonet 111, thereby effectively simplifying the sealing structure of the control device 100 and the assembly process of the control device 100.

[0107] In some embodiments of the present application, please refer to Figure 5, a second rib 15212 and a third rib 15213 are convexly provided on the outer peripheral side of the first sealing portion 1521, and the second rib 15212, the first rib 15211 and the third rib 15213 are spaced apart along the length direction of the liquid inlet connector 152 (the Y direction as shown in Figure 5), the second rib 15212 abuts against the outer wall of the box body 110, and the third rib 15213 abuts against the inner wall of the box body 110.

[0108] It can be understood that when the first sealing portion 1521 is fully engaged with the first retaining groove 111, the second rib 15212 abuts against the outer wall of the case 110, and the third rib 15213 abuts against the inner wall of the case 110. In other words, the outer diameter of the second rib 15212 is larger than the diameter of the first retaining groove 111, and the outer diameter of the third rib 15213 is larger than the diameter of the first retaining groove 111. The spacing between the second rib 15212 and the third rib 15213 along the length of the liquid inlet connector 152 is equal to the thickness of the sidewall of the case 110. Of course, to account for assembly tolerances, a slight gap may exist between the second rib 15212 and the outer wall of the case 110, and similarly, a slight gap may exist between the third rib 15213 and the inner wall of the case 110.

[0109] In this embodiment, the first bayonet 111 passes through the open end of the box body 110 to form a first notch, and the first sealing groove 114 is recessed in the inner edge of the first bayonet 111. The first sealing groove 114 extends along the length direction of the inner edge of the first bayonet 111, and the first sealing groove 114 passes through both ends of the inner edge of the first bayonet 111. The first sealing portion 1521 can enter the first bayonet 111 through the first notch, and at the same time, the first rib 15211 enters the first sealing groove 114, the second rib 15212 rests against the outer wall of the box body 110, and the third rib 15213 rests against the inner wall of the box body 110 until the first sealing portion 1521 is completely inserted into the first bayonet 111. At this time, the first rib 15211 cooperates with the first sealing groove 114 to block the gap between the outer peripheral side of the first sealing portion 1521 and the inner edge of the first bayonet 111, the second rib 15212 blocks the gap between the outer peripheral side of the first sealing portion 1521 and the edge of one port of the first bayonet 111, and the third rib 15213 blocks the gap between the outer peripheral side of the first sealing portion 1521 and the edge of the other port of the first bayonet 111.

[0110] By adopting the above technical solution, the sealing performance of the control device 100 is further improved.

[0111] In some embodiments of the present application, please refer to Figures 3 and 4 together. A second bayonet 112 is opened on the side wall of the box body 110, and a second sealing groove is provided on the inner edge of the second bayonet 112 (not shown in the figure, refer to the structure of the first sealing groove 114 shown in Figure 5). The liquid outlet connector 153 includes a second sealing portion 1531 arranged in the second bayonet 112, and a fourth rib is convexly provided on the outer peripheral side of the second sealing portion 1531 (not shown in the figure, refer to the structure of the first rib 15211 shown in Figure 5), and the fourth rib is inserted into the second sealing groove.

[0112] The second bayonet 112 is used to provide a mounting space for the liquid outlet connector 153. The shape of the second bayonet 112 can be, but is not limited to, circular, semicircular, square, trapezoidal, triangular, etc. The inner edge of the second bayonet 112 refers to the portion enclosing the inner space of the second bayonet 112.

[0113] The second sealing portion 1531 is used to seal the second bayonet 112. The outer contour of the second sealing portion 1531 is adapted to the shape of the second bayonet 112. For example, if the second bayonet 112 is semicircular, the outer contour of the second sealing portion 1531 is also semicircular. In some embodiments, the liquid outlet connector 153 may further include a third connecting portion 1532 and a fourth connecting portion 1533. The second sealing portion 1531 is connected between the third connecting portion 1532 and the fourth connecting portion 1533. The third connecting portion 1532 is connected to the external drainage pipe, and the fourth connecting portion 1533 is connected to the liquid cooling plate 151.

[0114] In some embodiments, the second bayonet 112 is recessed into the open end of the housing 110. In other words, the second bayonet 112 extends through the open end of the housing 110 to form a second notch. This allows the second bayonet 112 to connect the interior and exterior environments of the housing 110 along the thickness of the sidewall of the housing 110. The second bayonet 112 can also connect to the exterior environment of the housing 110 through the second notch. A second sealing groove is recessed into the inner edge of the second bayonet 112, extending along the length of the inner edge of the second bayonet 112 and extending through both ends of the inner edge of the second bayonet 112. The second sealing portion 1531 can enter the second bayonet 112 through the second notch, while the fourth rib simultaneously enters the second sealing groove until the second sealing portion 1531 is fully engaged with the second bayonet 112. At this point, the fourth rib cooperates with the second sealing groove to seal the gap between the outer periphery of the second sealing portion 1531 and the inner edge of the second bayonet 112.

[0115] In other embodiments, the second bayonet 112 passes through the sidewall of the housing 110 but not through the open end of the housing 110. In other words, the second bayonet 112 can only connect the internal environment of the housing 110 with the external environment along the thickness direction of the sidewall of the housing 110. The second sealing groove is recessed in the inner edge of the second bayonet 112 and extends along the length of the inner edge of the second bayonet 112 to form a closed loop structure. The fourth rib is a closed loop structure that surrounds the central axis of the liquid outlet connector 153. The outer diameter of the fourth rib is larger than the inner diameter of the second bayonet 112. As the second sealing portion 1531 passes through the second bayonet 112, the fourth rib is squeezed by the inner edge of the second bayonet 112 until the fourth rib enters the second sealing groove. At this point, the fourth rib cooperates with the second sealing groove to seal the gap between the outer periphery of the second sealing portion 1531 and the inner edge of the second bayonet 112. In this embodiment, to facilitate the fourth rib to enter the second sealing groove, the fourth rib can be made of a flexible material, which can be, but is not limited to, rubber, silicone, etc. Of course, in other embodiments, the second sealing portion 1531 and the fourth rib can be integrally formed of a flexible material.

[0116] In some embodiments, in order to further improve the sealing performance of the control device 100 , the second sealing groove may be filled with sealant.

[0117] By adopting the above technical solution, the liquid outlet connector 153 can be passed through the second bayonet 112 and the second bayonet 112 can be closed, thereby effectively improving the sealing performance of the control device 100. Moreover, there is no need to set up additional sealing parts to seal the second bayonet 112, thereby effectively simplifying the sealing structure of the control device 100 and the assembly process of the control device 100.

[0118] In some embodiments of the present application, a fifth rib (not shown in the figure, refer to the structure of the second rib 15212 shown in Figure 5) and a sixth rib (not shown in the figure, refer to the structure of the third rib 15213 shown in Figure 5) are convexly provided on the outer peripheral side of the second sealing portion 1531. The fifth rib, the fourth rib and the sixth rib are spaced apart along the length direction of the liquid outlet connector 153 (the Y direction as shown in Figure 5). The fifth rib abuts against the outer wall of the box body 110, and the sixth rib abuts against the inner wall of the box body 110.

[0119] It can be understood that when the second sealing portion 1531 is fully engaged with the second retaining groove 112, the fifth rib abuts against the outer wall of the box body 110, and the sixth rib abuts against the inner wall of the box body 110. In other words, the outer diameter of the fifth rib is larger than the diameter of the second retaining groove 112, and the outer diameter of the sixth rib is larger than the diameter of the second retaining groove 112. The spacing between the fifth and sixth ribs along the length of the liquid outlet connector 153 is equal to the thickness of the sidewall of the box body 110. Of course, to account for assembly errors, a small gap may exist between the fifth rib and the outer wall of the box body 110, and similarly, a small gap may exist between the sixth rib and the inner wall of the box body 110.

[0120] In this embodiment, the second bayonet 112 passes through the open end of the box body 110 to form a second notch, and the second sealing groove is recessed in the inner edge of the second bayonet 112. The second sealing groove extends along the length direction of the inner edge of the second bayonet 112, and the second sealing groove passes through both ends of the inner edge of the second bayonet 112. The second sealing portion 1531 can enter the second bayonet 112 through the second notch, and at the same time the fourth rib enters the second sealing groove, the fifth rib rests against the outer wall of the box body 110, and the sixth rib rests against the inner wall of the box body 110, until the second sealing portion 1531 is completely inserted into the second bayonet 112. At this time, the fourth rib cooperates with the second sealing groove to block the gap between the outer peripheral side of the second sealing portion 1531 and the inner edge of the second bayonet 112, the fifth rib blocks the gap between the outer peripheral side of the second sealing portion 1531 and the edge of one port of the second bayonet 112, and the sixth rib blocks the gap between the outer peripheral side of the second sealing portion 1531 and the edge of the other port of the second bayonet 112.

[0121] By adopting the above technical solution, the sealing performance of the control device 100 is further improved.

[0122] In some embodiments of the present application, please refer to Figure 5, an annular rib 1611 is protruded from the side of the box cover 160 facing the box body 110, and a third sealing groove (not shown in the figure) extending along the circumference of the opening end is formed at the open end of the box body 110, and the annular rib 1611 is inserted into the third sealing groove.

[0123] The annular rib 1611 protrudes from the side of the box cover 160 facing the box body 110 along the covering direction of the box cover 160 and the box body 110 (the opposite direction of the Z direction as shown in Figure 5). Correspondingly, the third sealing groove is recessed in the covering direction of the box cover 160 and the box body 110 at the edge of the open end of the box body 110. When the box cover 160 is covered on the open end of the box body 110, the annular rib 1611 is inserted into the third sealing groove.

[0124] By adopting the above technical solution, the gap between the box cover 160 and the box body 110 is effectively sealed, thereby effectively improving the sealing performance of the control device 100.

The third sealing groove, the fourth sealing groove 15214 and the fifth sealing groove are connected to form an annular groove, and the annular rib 1611 is inserted into the annular groove.

[0126] In this embodiment, the first bayonet 111 extends through the open end of the housing 110 to form a first notch, and the second bayonet 112 extends through the open end of the housing 110 to form a second notch. A fourth sealing groove 15214 is recessed on the side of the first sealing portion 1521 facing the first notch, and a fifth sealing groove is recessed on the side of the second sealing portion 1531 facing the second notch. When the first sealing portion 1521 is disposed within the first bayonet 111 and the second sealing portion 1531 is disposed within the second bayonet 112, the third, fourth, and fifth sealing grooves communicate to form an annular groove. The shape of the annular groove matches that of the annular rib 1611. For example, if the annular rib 1611 is square, the annular groove also has a square shape. When the housing cover 160 is disposed over the open end of the housing 110, the annular rib 1611 is inserted into the annular groove.

[0127] By adopting the above technical solution, not only the gap between the box cover 160 and the box body 110 can be closed, but also the first bayonet 111 and the second bayonet 112 can be closed, thereby effectively improving the sealing performance of the control device 100. Moreover, there is no need to set up additional sealing parts to seal the first bayonet 111 and the second bayonet 112, thereby effectively simplifying the sealing structure of the control device 100 and the assembly process of the control device 100.

The location of the escape opening 1511 depends on the location of the first terminal 133 and / or second terminal 143. For example, the escape opening 1511 can be located on one side of the liquid cooling plate 151, or in the middle of the liquid cooling plate 151.
