[0063] As people's living standards continue to improve, vehicles as a means of transportation have become widely popular. Vehicles include multiple electrical appliances, such as dashboards, head units, lights, electric seats, audio, steering gears, etc. At present, vehicles usually use batteries to provide power and rely on low-voltage power distribution modules to distribute power to various electrical appliances so that the electrical appliances can operate normally.

[0064] In the related art, batteries and low-voltage power distribution modules are usually distributed in different positions of the vehicle. This not only requires separate installation structures for the batteries and low-voltage power distribution modules, but also requires separate safety spacing for the batteries and low-voltage power distribution modules to reduce the risk of contact between the batteries and low-voltage power distribution modules and other components, resulting in a larger total space occupied by the batteries and low-voltage power distribution modules. In addition, in order to protect the batteries and low-voltage power distribution modules, it is usually necessary to separately configure a casing for the batteries and low-voltage power distribution modules, which increases the volume of the batteries and the volume of the low-voltage power distribution modules, further increasing the total space occupied by the batteries and the low-voltage power distribution modules, thereby significantly reducing the space utilization of the vehicle.

[0065] In order to improve the space utilization of the vehicle, the battery and low-voltage power distribution module of the control device provided in the embodiment of the present application are housed in a box, so that the battery and the low-voltage power distribution module are integrated into a whole. Compared with the dispersed arrangement of the battery and the low-voltage power distribution module, not only is there no need to separately allocate assembly space for the battery and the low-voltage power distribution 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 and the low-voltage power distribution 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.

[0066] The control device provided in the embodiment of the present application can be applied to an electrical device, and the control device can be used to distribute electric energy to each electrical appliance in the electrical device so that each electrical appliance in the electrical device can operate normally. The electrical device can be, but is not limited to, a vehicle, a portable device, a ship, a spacecraft, an electric toy, an electric tool, and the like. The vehicle can be a fuel vehicle, a gas vehicle, or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle, and the like. The spacecraft includes an airplane, a rocket, a space shuttle, and a spacecraft, and the like. Electric toys include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, and the like.

[0074] The box 110 is a component for providing an internal environment of the control device 100, wherein the internal environment can be used to accommodate the battery 120, the low-voltage distribution module 130 and other functional components. The box 110 can be an integrally formed component, and an opening 111 can be provided on the box 110, and the internal environment is connected to the external environment of the box 110 through the opening 111, and the battery 120, the low-voltage distribution module 130 and other functional components can enter the internal environment through the opening 111.

[0076] The battery 120 is a component for storing electrical energy. The battery 120 may include a battery cell, and there may be multiple battery cells. Multiple battery cells may be connected in series, in parallel, or in a hybrid connection to form a battery body. A hybrid connection means that multiple battery cells are both connected in series and in parallel. Multiple battery cells may be directly connected in series, in parallel, or in a hybrid connection, and then the whole formed by multiple battery cells is accommodated in the box 110. Of course, the battery 120 may also be a battery module formed by multiple battery cells connected in series, in parallel, or in a hybrid connection, and then multiple battery modules are connected in series, in parallel, or in a hybrid connection to form a whole, and accommodated in the box 110. Each battery cell may be a secondary battery or a primary battery, wherein a secondary battery refers to a battery cell that can be used continuously by activating the active material by charging after the battery cell is discharged, and a primary battery refers to a battery cell that cannot be used continuously by activating the active material by charging after the electric energy of the battery cell is exhausted; the battery cell may also be a lithium ion battery, a sodium ion battery, a sodium lithium ion battery, a lithium metal battery, a sodium metal battery, a lithium sulfur battery, a magnesium ion battery, a nickel hydrogen battery, a nickel cadmium battery, a lead storage battery, etc., but is not limited thereto.

The battery 120 can be fixed in the box 110 by a fixing structure, and the fixing structure can be, but is not limited to, a fastening structure, a snap-fit ​​structure, an adhesive structure, etc.

[0077] The low-voltage power distribution module 130 is a component for distributing the electric energy provided by the battery 120 to each electrical appliance 200. The low-voltage power distribution module 130 includes a circuit board 131 and a plurality of electronic components 132. The circuit board 131 is provided with a plurality of electric circuits (not shown in the figure).

The low-voltage power distribution module 130 can be fixed in the box 110 by a fixing structure, and the fixing structure can be but is not limited to a fastening structure, a snap-fit ​​structure, an adhesive structure, etc.

[0078] The control device 100 provided in the embodiment of the present application accommodates the battery 120 and the low-voltage power distribution module 130 in the box body 110, so that the battery 120 and the low-voltage power distribution module 130 are integrated into a whole. Compared with the dispersed arrangement of the battery 120 and the low-voltage power distribution module 130, not only is there no need to separately allocate assembly space for the battery 120 and the low-voltage power distribution module 130, which effectively saves the assembly space of the control device 100, but there is also no need to separately configure a shell for the battery 120 and the low-voltage power distribution module 130, 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.

[0079] In some embodiments of the present application, the box cover 140 is a metal piece.

[0080] In other words, the box cover 140 is made of metal material, which may be but not limited to aluminum, aluminum alloy, copper, iron, stainless steel, etc. The box cover 140 may be an integrally formed component, that is, the box cover 140 may be integrally formed by a die-casting process or a casting process.

[0081] By adopting the above technical solution, the heat inside the box body 110 can be quickly conducted outward through the box cover 140, thereby effectively improving the heat dissipation performance of the control device 100.

[0082] In some embodiments of the present application, the low-voltage power distribution module 130 is thermally connected to the box cover 140 .

[0083] It should be noted that the thermal connection between the low-voltage distribution module 130 and the box cover 140 means that the heat-generating part of the low-voltage distribution module 130 is in contact with the box cover 140, so that the heat generated by the heat-generating part of the low-voltage distribution module 130 is transferred to the box cover 140, thereby achieving the purpose of cooling the low-voltage distribution module 130.

[0084] In some embodiments, the top surface of the low-voltage distribution module 130 is arranged opposite to the bottom surface of the box cover 140, and the low-voltage distribution module 130 is thermally connected to the box cover 140, wherein the top surface of the low-voltage distribution module 130 refers to the surface of the low-voltage distribution module 130 facing away from the bottom of the box body 110, and the bottom surface of the box cover 140 refers to the surface of the box cover 140 facing the bottom of the box body 110.

[0085] By adopting the above-mentioned technical solution, the heat generated by the operation of the low-voltage distribution module 130 can be quickly conducted outward through the box cover 140, thereby effectively improving the efficiency of cooling the low-voltage distribution module 130, and no additional cooling components are required, which effectively reduces the number of components of the control device 100 and the production cost of the control device 100, while further reducing the volume of the control device 100, thereby further improving the space utilization of the vehicle 1000 using the above-mentioned control device 100.

[0086] In some embodiments of the present application, a heat conducting portion (not shown) is protruded from the surface of the box cover 140 facing the box body 110 , and the low-voltage power distribution module 130 is thermally connected to the heat conducting portion.

[0087] The heat-conducting part is a part used to contact the heating part of the low-voltage power distribution module 130. The number of heat-conducting parts can be one or more, depending on the number of heating parts of the low-voltage power distribution module 130. The heat-conducting part can be but not limited to a boss structure, a column structure, or a bump structure. The heat-conducting part has a contact surface for contacting the heating part of the low-voltage power distribution module 130, and the shape of the contact surface is determined according to the shape of the heating part of the low-voltage power distribution module 130. For example, the shape of the heating part of the low-voltage power distribution module 130 is circular, and the shape of the contact surface is also circular. In some embodiments, the top surface of the low-voltage power distribution module 130 is arranged opposite to the heat-conducting part, and the low-voltage power distribution module 130 is thermally connected to the heat-conducting part.

[0089] In some embodiments of this application, please refer to Figure 3 and Figure 4 The box cover 140 is provided with a wiring port 141 . The low voltage power distribution module 130 further includes an insulating member 134 . The insulating member 134 has a wiring channel 1341 . The wiring head 133 is disposed in the wiring channel 1341 . The insulating member 134 is passed through the wiring port 141 .

[0090] The connection head 133 is a part for electrically connecting to the electrical appliance 200. The number of the connection heads 133 can be multiple, depending on the actual application requirements.

[0091] The wiring port 141 is a part that connects the internal environment of the control device 100 with the external environment. The wiring head 133 can extend outward through the wiring port 141 so as to electrically connect the wiring head 133 with the corresponding electrical appliance 200 through a cable. The number of the wiring ports 141 can be multiple, depending on the number of the wiring heads 133.

[0092] The insulating member 134 is a component for insulating and separating the terminal head 133 from the box cover 140. It can be understood that the insulating member 134 is made of an insulating material, and the insulating material can be but is not limited to polypropylene, polyethylene, polyvinyl chloride, rubber, etc. In the case where the insulating member 134 is inserted into the wiring port 141, the insulating member 134 covers the inner wall of the wiring port 141, and the wiring channel 1341 of the insulating member 134 passes through the bottom surface and the top surface of the box cover 140. In other words, in the case where the box cover 140 is covered at the open end of the box body 110, the wiring channel 1341 of the insulating member 134 connects the internal environment and the external environment of the control device 100. In some embodiments, the top surface of the low-voltage distribution module 130 is arranged opposite to the bottom surface of the box cover 140, the terminal head 133 is arranged on the top surface of the low-voltage distribution module 130, and the terminal head 133 is inserted into the wiring channel 1341.

[0093] By adopting the above technical solution, the connection head 133 of the low-voltage power distribution module 130 is effectively insulated and separated from the box cover 140, thereby effectively improving the reliability of the control device 100.

[0094] In some embodiments of the present application, the insulating member 134 and the terminal head 133 are injection molded as one body.

[0097] Of course, in other embodiments, the insulating member 134 may also be formed in the wiring port 141 by using an injection molding process.

[0098] In some embodiments of this application, please refer to Figure 3 The control device 100 also includes a heat insulating member 150 , which is disposed between the low-voltage power distribution module 130 and the battery 120 .

[0099] The heat insulating member 150 is a component for isolating the heat transfer path between the low voltage power distribution module 130 and the battery 120. It can be understood that the heat insulating member 150 is made of a heat insulating material, and the heat insulating material can be but is not limited to glass fiber, asbestos, rock wool, silicate, etc.

[0100] In some embodiments, the thermal insulation member 150 is a plate-like structure, with the plate surface of the thermal insulation member 150 as a reference plane, and the projection of the battery 120 along a direction perpendicular to the plate surface of the thermal insulation member 150 is located within the reference plane. In other words, the thermal insulation member 150 can completely cover the battery 120.

[0101] By adopting the above technical solution, the heat generated by the low-voltage distribution module 130 is effectively blocked from being transferred to the battery 120, which effectively reduces the risk of thermal runaway of the battery 120, thereby effectively improving the reliability of the control device 100.

[0102] In some embodiments of this application, please refer to Figure 3 The low voltage power distribution module 130, the heat insulation member 150 and the battery 120 are arranged along the depth direction of the box body 110 (eg Figure 3 The Z direction is opposite to that shown in the figure) and they are stacked in sequence.

[0103] By adopting the above technical solution, the low-voltage distribution module 130, the thermal insulation 150 and the battery 120 can make more full use of the internal space of the box 110, so that the overall structure of the control device 100 becomes more compact, thereby further improving the space utilization of the vehicle 1000 using the above control device 100.

Of course, in other embodiments, the cooling module 160 can also be thermally connected to other components of the control device 100 to cool the components. For example, the cooling module 160 can also be thermally connected to the battery 120. The cooling module 160 can be, but not limited to, a liquid cooling module, an air cooling module, a metal thermal conductive module, etc. The cooling module 160 can be fixed in the box 110 by a fixed structure, and the fixed structure can be, but not limited to, a fastening structure, a snap-fit ​​structure, an adhesive structure, etc.

[0107] In some embodiments of this application, please refer to Figure 5 The cooling module 160 is disposed between the low-voltage power distribution module 130 and the battery 120 .

[0108] By adopting the above technical solution, it is not only convenient to cool the low-voltage distribution module 130, but also effectively prevents the heat generated by the operation of the low-voltage distribution module 130 from being transferred to the battery 120, and can also cool the battery 120 to a certain extent, effectively reducing the risk of thermal runaway of the battery 120, thereby effectively improving the reliability of the control device 100.

[0109] In some embodiments of this application, please refer to Figure 5 The low voltage power distribution module 130, the cooling module 160 and the battery 120 are arranged along the depth direction of the box body 110 (eg Figure 5 The Z direction is opposite to that shown in the figure) and they are stacked in sequence.

For example, the low-voltage distribution module 130 is connected to the side of the cooling module 160 facing the box cover 140 through fasteners, and the cooling module 160 is connected to the connecting seat 115 through fasteners.

[0114] By adopting the above technical solution, the low-voltage power distribution module 130 and the cooling module 160 can be first connected into a whole, and then the whole can be assembled into the box body 110, thereby effectively improving the assembly efficiency of the control device 100.

[0119] The liquid outlet connector 163 is a component used to connect to an external liquid discharge pipeline and output the cooling medium to the outside of the cooling channel. The liquid outlet connector 163 and the liquid cooling plate 161 can be an integrally formed component, that is, the liquid outlet connector 163 and the liquid cooling plate 161 are integrally formed, and the liquid outlet connector 163 and the liquid cooling plate 161 can also be connected separately, for example, the liquid outlet connector 163 can be welded to the liquid cooling plate 161 to form a whole.

[0120] By adopting the above technical solution, the efficiency of the cooling module 160 in cooling the low-voltage power distribution module 130 is effectively improved, thereby effectively improving the reliability of the control device 100.

[0121] In some embodiments of this application, please refer to Figures 5 to 7 A first bayonet 112 is provided on the side wall of the box body 110, and a first sealing groove 114 is provided on the inner edge of the first bayonet 112. The liquid inlet connector 162 includes a first sealing portion 1621 arranged in the first bayonet 112, and a first rib 16211 is convexly provided on the outer peripheral side of the first sealing portion 1621, and the first rib 16211 is inserted into the first sealing groove 114.

[0122] The first bayonet 112 is used to provide installation space for the liquid inlet connector 162. The shape of the first bayonet 112 can be, but not limited to, circular, semicircular, square, trapezoidal, triangular, etc. The inner edge of the first bayonet 112 refers to the part enclosing the inner space of the first bayonet 112.

[0123] The first sealing portion 1621 is used to seal the first bayonet 112. The outer contour of the first sealing portion 1621 is adapted to the shape of the first bayonet 112. For example, when the shape of the first bayonet 112 is semicircular, the outer contour of the first sealing portion 1621 is also semicircular. In some embodiments, the liquid inlet connector 162 may further include a first connection portion 1622 and a second connection portion 1623, the first sealing portion 1621 is connected between the first connection portion 1622 and the second connection portion 1623, the first connection portion 1622 is connected to an external liquid supply pipeline, and the second connection portion 1623 is connected to the liquid cooling plate 161.

[0124] In some embodiments, the first bayonet 112 is recessed at the open end of the box body 110. In other words, the first bayonet 112 passes through the open end of the box body 110 to form a first notch, that is, the first bayonet 112 can be formed along the thickness direction of the side wall of the box body 110 (such as Figure 5 and Figure 7The first notch (in the Y direction shown) connects the internal environment and the external environment of the housing 110, and the first bayonet 112 can also connect the external environment of the housing 110 through the first notch. The first sealing groove 114 is recessed in the inner edge of the first bayonet 112, and the first sealing groove 114 extends along the length direction of the inner edge of the first bayonet 112, and the first sealing groove 114 passes through both ends of the inner edge of the first bayonet 112. The first sealing portion 1621 can enter the first bayonet 112 through the first notch, and the first rib 16211 enters the first sealing groove 114 at the same time, until the first sealing portion 1621 is completely inserted into the first bayonet 112. At this time, the first rib 16211 cooperates with the first sealing groove 114 to block the gap between the outer peripheral side of the first sealing portion 1621 and the inner edge of the first bayonet 112.

[0125] In other embodiments, the first bayonet 112 passes through the side wall of the box body 110 but does not pass through the open end of the box body 110. In other words, the first bayonet 112 can only connect the internal environment and the external environment of the box body 110 along the thickness direction of the side wall of the box body 110. The first sealing groove 114 is recessed at the inner edge of the first bayonet 112, and the first sealing groove 114 extends along the length direction of the inner edge of the first bayonet 112 to form a closed loop structure. The first rib 16211 is a closed loop structure surrounding the central axis of the liquid inlet connector 162, and the outer diameter of the first rib 16211 is larger than the inner diameter of the first bayonet 112. In this way, when the first sealing portion 1621 passes through the first bayonet 112, the first rib 16211 will be squeezed by the inner edge of the first bayonet 112 until the first rib 16211 enters the first sealing groove 114. At this time, the first rib 16211 cooperates with the first sealing groove 114 to block the gap between the outer peripheral side of the first sealing portion 1621 and the inner edge of the first bayonet 112. In this embodiment, in order to facilitate the first rib 16211 to enter the first sealing groove 114, the first rib 16211 can be made of a flexible material, and the flexible material can be but is not limited to rubber, silicone, etc. Of course, in other implementations, the first sealing portion 1621 and the first rib 16211 can be integrally formed with a flexible material.

[0126] In some embodiments, in order to further improve the sealing performance of the control device 100 , a sealant may be filled into the first sealing groove 114 .

Moreover, there is no need to additionally set a seal to seal the first bayonet 112, thereby effectively simplifying the sealing structure of the control device 100 and the assembly process of the control device 100.

The second ribs 16212 are against the outer wall of the box body 110, and the third ribs 16213 are against the inner wall of the box body 110.

[0129] It can be understood that when the first sealing portion 1621 is completely inserted into the first bayonet 112, the second rib 16212 abuts against the outer wall of the box body 110, and the third rib 16213 abuts against the inner wall of the box body 110. In other words, the outer diameter of the second rib 16212 is greater than the caliber of the first bayonet 112, the outer diameter of the third rib 16213 is greater than the caliber of the first bayonet 112, and the spacing between the second rib 16212 and the third rib 16213 along the length direction of the liquid inlet connector 162 is equal to the thickness of the side wall of the box body 110. Of course, in consideration of assembly errors, there may be a small gap between the second rib 16212 and the outer wall of the box body 110, and similarly, there may be a small gap between the third rib 16213 and the inner wall of the box body 110.

[0130] In this embodiment, the first bayonet 112 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 112. The first sealing groove 114 extends along the length direction of the inner edge of the first bayonet 112, and the first sealing groove 114 passes through both ends of the inner edge of the first bayonet 112. The first sealing portion 1621 can enter the first bayonet 112 through the first notch, and at the same time the first rib 16211 enters the first sealing groove 114, the second rib 16212 abuts against the outer wall of the box body 110, and the third rib 16213 abuts against the inner wall of the box body 110, until the first sealing portion 1621 is completely inserted into the first bayonet 112. At this time, the first rib 16211 cooperates with the first sealing groove 114 to block the gap between the outer peripheral side of the first sealing portion 1621 and the inner edge of the first bayonet 112, the second rib 16212 blocks the gap between the outer peripheral side of the first sealing portion 1621 and the edge of one port of the first bayonet 112, and the third rib 16213 blocks the gap between the outer peripheral side of the first sealing portion 1621 and the edge of the other port of the first bayonet 112.

[0133] The second bayonet 113 is a part for providing installation space for the liquid outlet connector 163. The shape of the second bayonet 113 can be, but not limited to, circular, semicircular, square, trapezoidal, triangular, etc. The inner edge of the second bayonet 113 refers to the part enclosing the inner space of the second bayonet 113.

[0134] The second sealing portion 1631 is used to block the second bayonet 113. The outer contour shape of the second sealing portion 1631 is adapted to the shape of the second bayonet 113. For example, when the shape of the second bayonet 113 is semicircular, the outer contour shape of the second sealing portion 1631 is also semicircular. In some embodiments, the liquid outlet connector 163 may further include a third connecting portion 1632 and a fourth connecting portion 1633, the second sealing portion 1631 is connected between the third connecting portion 1632 and the fourth connecting portion 1633, the third connecting portion 1632 is connected to the external drainage pipe, and the fourth connecting portion 1633 is connected to the liquid cooling plate 161.

[0135] In some embodiments, the second bayonet 113 is recessed at the open end of the box body 110. In other words, the second bayonet 113 penetrates the open end of the box body 110 to form a second notch, that is, the second bayonet 113 can connect the internal environment and the external environment of the box body 110 along the thickness direction of the side wall of the box body 110, and the second bayonet 113 can also connect the external environment of the box body 110 through the second notch. The second sealing groove is recessed at the inner edge of the second bayonet 113, the second sealing groove extends along the length direction of the inner edge of the second bayonet 113, and the second sealing groove penetrates both ends of the inner edge of the second bayonet 113. The second sealing portion 1631 can enter the second bayonet 113 through the second notch, and the fourth rib enters the second sealing groove until the second sealing portion 1631 is completely inserted into the second bayonet 113. 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 1631 and the inner edge of the second bayonet 113.

[0136] In other embodiments, the second bayonet 113 penetrates the side wall of the box body 110 but does not penetrate the open end of the box body 110. In other words, the second bayonet 113 can only connect the internal environment and the external environment of the box body 110 along the thickness direction of the side wall of the box body 110. The second sealing groove is recessed at the inner edge of the second bayonet 113, and the second sealing groove extends along the length direction of the inner edge of the second bayonet 113 to form a closed loop structure. The fourth rib is a closed loop structure surrounding the central axis of the liquid outlet joint 163, and the outer diameter of the fourth rib is greater than the inner edge diameter of the second bayonet 113.

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 1631 and the inner edge of the second bayonet 113.

Moreover, there is no need to additionally set a seal to seal the second bayonet 113, thereby effectively simplifying the sealing structure of the control device 100 and the assembly process of the control device 100.

[0139] In some embodiments of the present application, a fifth convex rib is convexly disposed on the outer circumference of the second sealing portion 1631 (not shown in the figure, refer to Figure 7 The structure of the second rib 16212 shown in the figure) and the sixth rib (not shown in the figure, refer to Figure 7 The structure of the third rib 16213 shown in the figure), the fifth rib, the fourth rib and the sixth rib are along the length direction of the liquid outlet connector 163 (such as Figure 7 The fifth convex rib abuts against the outer wall of the box body 110, and the sixth convex rib abuts against the inner wall of the box body 110.

In other words, the outer diameter of the fifth convex rib is greater than the caliber of the second bayonet 113, the outer diameter of the sixth convex rib is greater than the caliber of the second bayonet 113, and the spacing between the fifth convex rib and the sixth convex rib along the length direction of the liquid outlet connector 163 is equal to the thickness of the side wall of the box body 110. Of course, in consideration of assembly errors, there may be a small gap between the fifth convex rib and the outer wall of the box body 110, and similarly, there may be a small gap between the sixth convex rib and the inner wall of the box body 110.

For example, when the shape of the annular rib 142 is a square ring, the shape of the annular groove is also a square ring. When the box cover 140 is disposed on the open end of the box body 110, the annular rib 142 is inserted into the annular groove.

[0148] By adopting the above technical solution, not only the gap between the box cover 140 and the box body 110 can be closed, but also the first bayonet 112 and the second bayonet 113 can be closed, thereby effectively improving the sealing performance of the control device 100, and there is no need to additionally set up a seal to seal the first bayonet 112 and the second bayonet 113, thereby effectively simplifying the sealing structure of the control device 100 and the assembly process of the control device 100.
