[0061] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0062] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can 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 can be directly connected to the other element or indirectly connected to the other element.

[0063] 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 drawings, and are only for the convenience of describing the present 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 should not be understood as a limitation on the present application.

[0064] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0065] 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 instrument panels, car computers, lights, electric seats, audio, steering gears, etc. Vehicles also include multiple thermal management actuators, such as water pumps, flow valves, fan motors, air conditioning compressors, etc. At present, vehicles usually use batteries to provide power and rely on low-voltage distribution modules to distribute power to various electrical appliances. For thermal management actuators, thermal management modules are also required to drive and control the thermal management actuators.

[0066] In the related art, 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.

[0067] 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, making the overall structure of the control device more compact, thereby effectively improving the space utilization of the vehicle using the above-mentioned control device.

[0068] The control device provided in the embodiment of the present application can be applied to electrical equipment, and the control device can be used to distribute electric energy to each electrical appliance in the electrical equipment, and can also be used to drive and control each thermal management actuator in the electrical equipment.

[0087] 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 body 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 there is also 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.

[0088] In some embodiments of this application, please refer to Figure 3 The control device 100 further includes a cooling module 150 , which is disposed 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 .

[0089] The cooling module 150 is a component for absorbing 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 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.

[0094] The liquid inlet connector 152 is a component used to connect to an external liquid supply pipeline and input the cooling medium into the interior of the cooling channel. The liquid inlet connector 152 and the liquid cooling plate 151 can be an integrally formed component, that is, the liquid inlet connector 152 and the liquid cooling plate 151 are integrally formed, and the liquid inlet connector 152 and the liquid cooling plate 151 can also be connected separately, for example, the liquid inlet connector 152 can be welded to the liquid cooling plate 151 to form a whole.

[0095] The liquid outlet connector 153 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 inlet connector 152 includes a first sealing portion 1521 arranged in the first bayonet 111, and a first rib 15211 is convexly provided on the outer peripheral side of the first sealing portion 1521, and the first rib 15211 is inserted into the first sealing groove 114.

[0098] The first bayonet 111 is a part for providing installation space for the liquid inlet connector 152. The shape of the first bayonet 111 can be, but not limited to, circular, semicircular, square, trapezoidal, triangular, etc. The inner edge of the first bayonet 111 refers to the part enclosing the inner space of the first bayonet 111.

[0099] The first sealing portion 1521 is a portion for sealing the first bayonet 111. The outer contour shape of the first sealing portion 1521 is adapted to the shape of the first bayonet 111. For example, when the shape of the first bayonet 111 is semicircular, the outer contour shape 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 an external liquid supply pipeline, and the second connecting portion 1523 is connected to the liquid cooling plate 151.

[0100] In some embodiments, the first bayonet 111 is recessed at the open end of the box body 110. In other words, the first bayonet 111 penetrates the open end of the box body 110 to form a first notch, that is, the first bayonet 111 can be along the thickness direction of the side wall of the box body 110 (such as Figure 5 The first notch (in the Y direction shown) connects the internal environment and the external environment of the box body 110, and the first bayonet 111 can also connect the external environment of the box body 110 through the first notch. The first sealing groove 114 is recessed in the inner edge of the first bayonet 111, and 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 the first rib 15211 enters the first sealing groove 114 at the same time, 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.

[0101] In other embodiments, the first bayonet 111 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 111 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 111, and the first sealing groove 114 extends along the length direction of the inner edge of the first bayonet 111 to form a closed loop structure. The first rib 15211 is a closed loop structure surrounding the central axis of the liquid inlet connector 152, and the outer diameter of the first rib 15211 is larger than the inner diameter of the first bayonet 111. In this way, when the first sealing portion 1521 passes through the first bayonet 111, the first rib 15211 will be squeezed by the inner edge of the first bayonet 111 until the first rib 15211 enters the first sealing groove 114. 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. In this embodiment, in order to facilitate the first rib 15211 to enter the first sealing groove 114, the first rib 15211 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 1521 and the first rib 15211 can be integrally formed with a flexible material.

In other words, the outer diameter of the second rib 15212 is greater than the caliber of the first bayonet 111, and the outer diameter of the third rib 15213 is greater than the caliber of the first bayonet 111. The spacing between the second rib 15212 and the third rib 15213 along the length direction of the liquid inlet connector 152 is equal to the thickness of the side wall of the box body 110. Of course, in the case of considering the assembly error, there may be a small gap between the second rib 15212 and the outer wall of the box body 110, and similarly, there may be a small gap between the third rib 15213 and the inner wall of the box body 110.

[0106] 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 at 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 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, until the first sealing portion 1521 is completely inserted into the first bayonet 111.

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.

[0112] In other embodiments, the second 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 second 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 second sealing groove is recessed at the inner edge of the second bayonet 112, and the second sealing groove extends along the length direction of the inner edge of the second bayonet 112 to form a closed loop structure. The fourth rib is a closed loop structure surrounding the central axis of the liquid outlet joint 153, and the outer diameter of the fourth rib is greater than the inner edge diameter of the second bayonet 112.
