[0078] According to an embodiment of the present application, a housing is provided. A cavity is provided inside the housing, and a partition is provided inside the cavity. The partition divides the cavity into a first functional chamber and a second functional chamber. The first functional chamber is adapted to accommodate electromagnetic sensitive devices, and the second functional chamber is adapted to accommodate strong interference devices. The partition is suitable for electromagnetic shielding between the first functional chamber and the second functional chamber.

[0079] As Figure 1 shown, the overall shape of the housing is a cuboid. At least one of the housing and the partition is made of metal. The metal material can effectively perform electromagnetic shielding, thereby attenuating the noise generated by the strong interference device. The metal material can be but is not limited to aluminum, copper, iron, nickel, etc. The metal material is not limited to the above embodiments, and those skilled in the art can set it according to actual needs.

[0080] The housing is prepared by means of casting, welding, riveting, etc. Of course, the shapes of the housing, the first functional chamber, and the second functional chamber are not limited herein, and those skilled in the art can set them according to actual needs.

[0081] In the embodiment of the present application, the housing is provided with a cavity, and a partition is provided inside the cavity. The partition divides the cavity into a first functional chamber and a second functional chamber, and the partition is suitable for electromagnetic shielding between the first functional chamber and the second functional chamber. The first functional chamber is adapted to accommodate electromagnetic sensitive devices, and the second functional chamber is adapted to accommodate strong interference devices. In this way, the electromagnetic shielding of the strong interference device can be effectively shielded, and the electromagnetic sensitive device can be avoided from being interfered by noise.

[0082] In one example, the partition divides the second functional chamber into a second shielding chamber 12 and a third shielding chamber.

[0083] AsFigure 1 As shown, the second shielding chamber and the third shielding chamber are respectively used to accommodate different strong interference devices. In this way, electromagnetic shielding is formed between the strong interference devices, which can avoid mutual interference between the strong interference devices.

[0084] In one example, the partition forms a water channel structure, and the water channel structure is adapted to perform heat exchange on at least one of the strong interference device and the electromagnetic sensitive device.

[0085] As Figure 1 shown, a water channel is provided inside the water channel structure 15. The water channel is used to circulate a heat exchange medium. The heat exchange medium is, for example, water, a phase change heat exchange material, etc. The heat exchange medium can perform heat exchange on at least one of the power semiconductor module 106, the power conversion module, and the inductor module 114. In this example, in addition to shielding noise signals, the partition can also play a role in heat exchange, so that there is no need to additionally provide a heat dissipation structure inside the cavity. This setting method further improves the space utilization rate inside the control device 100.

[0086] Of course, the specific setting method of the water channel structure 15 is not limited herein, and those skilled in the art can set it according to actual needs.

[0087] In one example, the second shielding support plate includes a water channel structure 15, and the water channel structure 15 is adapted to conduct heat on the strong interference device.

[0088] As Figure 1 shown, a water channel is formed inside the second shielding support plate. The water channel is used to pass through a heat exchange medium. In addition to shielding noise signals, the second shielding support plate can also play a role in heat exchange, so that there is no need to additionally provide a heat dissipation structure inside the cavity. This setting method further improves the space utilization rate inside the control device 100.

[0089] In one example, the water channel structure 15 is connected to a water inlet pipe 124 and a water outlet pipe 118. The water inlet pipe 124 and the water outlet pipe 118 are respectively located on opposite sides of the housing, and the height of the water inlet pipe 124 from the bottom of the housing is greater than the height of the water outlet pipe 118 from the bottom of the housing.

[0090] As Figure 2 、 Figure 3 and Figure 6As shown, the overall housing is in a cuboid structure. The inlet pipe 124 and the outlet pipe 118 are respectively arranged on opposite sides of the main body part 112. Both the inlet pipe 124 and the outlet pipe 118 include elbow pipes, and their mouths are arranged downward. The inlet pipe 124 and the outlet pipe 118 are respectively connected to the vehicle's cooling system. In this example, the height from the inlet pipe 124 to the bottom of the housing is greater than the height from the outlet pipe 118 to the bottom of the housing. The heat exchange medium entering the water channel structure 15 of the cooling system adopts the way of high inlet and low outlet. This setting method can effectively exhaust the water channel structure 15, thus effectively avoiding the formation of air resistance in the water channel structure 15 and avoiding the decrease in the flow rate of the heat exchange medium in the water channel structure 15 due to air resistance.

[0091] In one example, an exhaust pipe 123 is connected to the outlet pipe 118.

[0092] As Figure 2 、 Figure 3 and Figure 6 shown, the outlet pipe 118 includes an elbow pipe. The elbow pipe bends downward. An exhaust pipe 123 is arranged on the upper side of the elbow pipe. For example, an exhaust valve is arranged on the exhaust pipe 123. When the heat exchange medium flows out from the outlet pipe 118, air resistance is likely to form on the upper side inside the outlet pipe 118, especially on the upper side inside the elbow pipe, thus causing the flow rate of the heat exchange medium in the water channel structure 15 to decrease. By arranging the exhaust pipe 123, the gas on the upper side inside the outlet pipe 118 can be effectively discharged, thus avoiding the formation of air resistance at this place and increasing the flow rate of the heat exchange medium.

[0093] In one example, the housing includes a top cover 101, a main body part 112 and a bottom cover 116. A cavity is formed inside the main body part 112. The top cover 101 is covered on the top of the main body part 112, and the bottom cover 116 is arranged at the bottom of the main body part 112.

[0094] As Figure 1 、 Figure 2 shown, the main body part includes a plurality of side walls. The plurality of side walls are sequentially connected end to end to form a hollow structure with open top and bottom. The top cover 101 and the bottom cover 116 are respectively fixed to the top and bottom of the main body part 112 by means of bolt connection, snap connection, riveting, etc. Those skilled in the art can set the specific structures of the top cover 101, the main body part 112 and the bottom cover 116 according to actual needs.

[0095] In one example, the partition includes a first shielding support plate 105 and a second shielding support plate. The first shielding support plate 105 and the second shielding support plate are located inside the cavity. The first functional chamber is located between the top cover 101 and the first shielding support plate 105. The second shielding chamber 12 is located between the first shielding support plate 105 and the second shielding support plate. The third shielding chamber is located between the second shielding support plate and the bottom cover 116.

[0096] As Figure 1 , Figure 2 shown, the top cover 101, the first shielding support plate 105, the second shielding support plate, and the bottom cover 116 are arranged in sequence from top to bottom along the height direction of the housing. The first functional chamber includes a first shielding chamber 11. A first shielding chamber 11 is formed between the top cover 101 and the first shielding support plate 105. The low-voltage control module 104 is fixed on the first shielding support plate 105 by means of bolt connection, clamping, riveting, etc. A second shielding chamber 12 is formed between the first shielding support plate 105 and the second shielding support plate. The power semiconductor module 106 is fixed on the second shielding support plate or the body portion 112 by means of bolt connection, clamping, riveting, etc. The first sub-chamber 13 is located between the second shielding support plate and the bottom cover 116. The power conversion module is fixed on the second shielding support plate or the body portion 112 by means of bolt connection, clamping, riveting, etc. In this example, the first shielding chamber 11, the second shielding chamber 12, and the first sub-chamber 13 are stacked, and this arrangement can make full use of the space inside the cavity.

[0097] In addition, the power conversion module is shielded by the first shielding support plate 105 and the second shielding support plate, which can more effectively prevent the low-voltage control module 104 from being interfered by noise signals.

[0098] Of course, the arrangement of the three shielding chambers is not limited to the above embodiments, and those skilled in the art can set it according to actual needs.

[0099] In one example, the partition further includes a retaining wall 16. The retaining wall 16 is connected to the second shielding support plate, and the retaining wall 16 divides the third shielding chamber into a first sub-chamber 13 and a second sub-chamber 14.

[0100] As Figure 1As shown, the retaining wall 16 is formed by extending downward from the second shielding support plate. The retaining wall 16 divides the space between the second shielding support plate and the bottom cover 116 into a first sub-chamber 13 and a second sub-chamber 14. The inductor module 114 is located in the second sub-chamber 14. The inductor module 114 is fixed to the second shielding support plate or the body portion 112 by means such as bolt connection, snap connection, riveting, etc. In this example, the retaining wall 16 can effectively shield the noise signal of the inductor module 114. In addition, the inductor module 114 is shielded by the first shielding support plate 105 and the second shielding support plate, which can more effectively prevent the low-voltage control module 104 from being interfered by noise signals.

[0101] Of course, the setting manner of the four shielding chambers is not limited to the above embodiments, and those skilled in the art can set it according to actual needs.

[0102] Optionally, the retaining wall 16 and the second shielding support plate are integrally formed.

[0103] For example, the retaining wall 16 and the second shielding support plate are integrally formed by casting, which makes the connection between the two easy and has high connection strength.

[0104] Of course, the retaining wall 16 and the second shielding support plate can also be fixed together by means such as bolt connection, snap connection, welding, riveting, etc.

[0105] In one example, at least one of the first shielding support plate 105 and the second shielding support plate is detachably connected to the body portion 112.

[0106] As Figure 2 shown, the first shielding support plate 105 is detachably connected to the body portion 112. This setting manner facilitates the installation and replacement of each component in the cavity. For example, before the first shielding support plate 105 is installed into the cavity, the low-voltage control module 104 is first fixed to the first shielding support plate 105, for example, the two are fixed together by means such as bolt connection, snap connection, riveting, etc., so as to form an integral structure. Then, this integral structure is fixed into the cavity. In this way, it can effectively avoid the difficulty in connecting the first shielding support plate 105 and the low-voltage control module 104 due to the narrow space in the cavity.

[0107] In addition, when it is necessary to replace components, especially the components near the bottom of the body portion 112, the first shielding support plate 105 and / or the second shielding support plate can be removed first, which can provide an operating space for the installation of components.

[0108] Of course, the specific structures and installation manners of the first shielding support plate 105 and the second shielding support plate are not limited to the above embodiments, and those skilled in the art can set them according to actual needs.

[0109] According to another embodiment of the present application, a control device 100 is provided. The control device 100 includes an electromagnetic sensitive device, a strong interference device, and the housing described in the present application. The electromagnetic sensitive device is located in the first functional chamber, and the strong interference device is located in the second functional chamber.

[0110] As Figures 1 to 6 shown, the electromagnetic sensitive device includes a low-voltage control module 104. The strong interference device includes a power semiconductor module 106, a power conversion module, and an inductor module 114. The low-voltage control module 104, the power semiconductor module 106, the power conversion module, and the inductor module 114 are connected. A cavity is provided in the housing, and a partition is provided in the cavity. The partition divides the cavity into a first shielding chamber 11, a second shielding chamber 12, a first sub-chamber 13, and a second sub-chamber 14. The low-voltage control module 104 is located in the first shielding chamber 11, the power semiconductor module 106 is located in the second shielding chamber 12, the power conversion module is located in the first sub-chamber 13, and the inductor module 114 is located in the second sub-chamber 14.

[0111] As Figure 1 shown, the control device 100 may be, but is not limited to, used to control the electric drive assembly 200 of a vehicle. The low-voltage control module 104 is used to control low-voltage components. The low-voltage control module 104 is easily interfered by noise signals. The power semiconductor module 106 is used for circuit control. The power conversion module is used for power conversion. The inductor module 114 is used to attenuate electromagnetic interference. The power semiconductor module 106, the power conversion module, and the inductor module 114 are all strong interference sources. For example, they can generate high-voltage noise, and the high-voltage noise can be coupled to the low-voltage control module 104, thereby interfering with the low-voltage control module 104. The strong interference sources will not only interfere with the low-voltage control module 104, but also interfere with each other among the strong interference sources. In the embodiment of the present application, the partition divides the cavity in the housing into multiple shielding chambers. The shielding chambers can effectively prevent the noise signals of the strong interference sources from being conducted to the outside of the shielding chambers, and can also shield the noise signals outside the shielding chambers.

The first circuit board is used to install the first motor controller. The second circuit board is used to install the second motor controller. The power conversion module includes an OBC and DCDC integrated module 117. The OBC and DCDC integrated module 117 integrates the OBC module and DCDC together for easy installation. This method improves the space utilization rate inside the cavity.

[0113] As Figures 2 to 6 shown, the DC bus plug-in 111 is adapted to be connected to the battery pack. The DC bus plug-in 111 is connected to the filtering assembly 110, and the filtering assembly 110 can effectively filter electromagnetic interference. The boost copper bar assembly 107 is respectively connected to the inductor module 114, the first motor controller, and the capacitor module 122. The inductor module 114 and the capacitor module 122 are used for filtering. The capacitor module 122 is respectively connected to the first motor controller and the second motor controller. The first motor controller is adapted to be connected to the generator of the electric drive assembly 200. The second motor controller is adapted to be connected to the drive motor of the electric drive assembly 200. The low-voltage control module 104 controls the first motor controller and the second motor controller respectively. The power distribution assembly 109 is connected to the filtering assembly 110. Among them, a fuse is assembled inside the power distribution assembly 109. The power distribution assembly 109 can distribute power to the OBC and DCDC integrated module 117, and can also distribute power to the PTC module, vehicle air conditioner, etc. through the power distribution plug-in 121. A power distribution observation port and a bus observation port are provided on the top cover 101. A power distribution cover plate 102 is installed on the power distribution observation port. A bus cover plate 103 is installed on the bus observation port. The power distribution cover plate 102 is disposed opposite to the power distribution assembly. A three-phase observation port is provided in the body portion 112. The three-phase observation port is used to observe the three-phase wiring of the first wiring socket 115. A three-phase wiring cover plate 113 is installed on the three-phase observation port. The first wiring socket 115 is used to be connected to the second wiring socket of the electric drive assembly 200. The power distribution plug-in 121, the DC plug-in 120, and the AC charging plug-in 119 are respectively used to supply power to different external devices.

[0114] In the embodiment of the present application, the control device 100 can effectively avoid the mutual interference between the low-voltage control module 104, the power semiconductor module 106, the power conversion module, and the inductor module 114, making the control signal of the control device 100 more accurate.

[0115] In one example, a heat-conducting element is disposed between at least one of the strong interference device and the electromagnetic sensitive device and the partition board.

[0116] For example, a heat-conducting element is disposed between at least one of the power semiconductor module 106, the power conversion module, and the inductor module 114 and the water channel structure 15. The heat-conducting element includes heat-conducting silica gel, heat-conducting silicone grease, etc. The heat-conducting element can effectively improve the heat exchange speed between the power semiconductor module 106, the power conversion module, the inductor module 114 and the heat-conducting element, so as to be able to dissipate heat from the power semiconductor module 106, the power conversion module, and the inductor module 114 more effectively.

[0117] Preferably, the power semiconductor module 106, the power conversion module, and the inductor module 114 share the water channel structure 15, thereby improving the heat exchange efficiency of the three modules.

[0118] Of course, the heat-conducting element is not limited to the above embodiments, and those skilled in the art can set it according to actual needs.

[0119] According to another embodiment of the present application, an electrical equipment is provided. The electrical equipment includes the control device 100 described in the present application.

[0120] The electrical equipment can be, but is not limited to, the power system of a vehicle. This electrical equipment has the characteristics of accurate control signals and a compact structure.

[0121] In one example, the electrical equipment further includes an electric drive assembly 200, and the control device 100 is connected to the electric drive assembly 200.

[0122] As Figure 7 shown, the electric drive assembly 200 is used to output power outward. The control device 100 can control the power supply of the electric drive assembly 200. This electrical equipment integrates a control device and an electric drive assembly. When assembling with other devices, the electrical equipment is connected to other devices as a whole, saving the installation process.

[0123] In one example, the control device 100 is provided with a first terminal block 115, the electric drive assembly is provided with a second terminal block, and the first terminal block 115 and the second terminal block are electrically connected.

[0124] As Figure 7 shown in A, the first terminal block 115 of the control device 100 is connected to the second terminal block of the electric drive assembly 200. The first terminal block 115 and the second terminal block are connected in a plug-in manner. Of course, the connection manner between the two is not limited to this, and those skilled in the art can set it according to actual needs.

[0125] In one example, a conductive component 18 is provided between the first terminal block 115 and the second terminal block.

[0126] For example, there is a gap at the connection between the first terminal block 115 and the second terminal block. The electromagnetic radiation between the first terminal block 115 and the second terminal block is conducted outward through this gap. In this example, as Figure 9 shown, the conductive component 18 is provided at the gap between the two. Preferably, the conductive component 18 is in contact with the housing, and the two together form an electromagnetic shielding effect. The conductive component 18 can effectively shield the electromagnetic radiation between the first terminal block 115 and the second terminal block.

[0127] Optionally, the material of the conductive component 18 is a material such as metal, conductive ceramic, carbon fiber, etc. Those skilled in the art can select according to actual needs.

[0128] In one example, the conductive component 18 has an annular structure, and the conductive component 18 is arranged around the edges of the first terminal block 115 and the second terminal block.

[0129] As Figure 8 , Figure 9 shown, the overall shape of the conductive component 18 is a racetrack-shaped annular structure. The conductive component 18 is mounted on the housing. For example, the conductive component 18 is provided with mounting holes 20, and bolts pass through the mounting holes 20 to fix the conductive component 18 to the housing. The conductive component 18 is arranged around the edge of the first socket, so as to be able to fill the gap between the first socket and the second socket. The annular conductive component 18 can effectively shield the electromagnetic interference conducted outward through the gap between the first terminal block 115 and the second terminal block.

[0130] Optionally, the conductive component 18 can also be a rectangular ring, a circular ring, an elliptical ring, a triangular ring, etc.

[0131] Of course, the shape of the conductive component 18 is not limited to the above embodiments, and those skilled in the art can set it according to actual needs.

[0132] In one example, elastic contacts 19 are provided on the surface in the thickness direction of the conductive component 18.

[0133] As Figure 9 shown, the elastic contacts 19 are protruding structures or elastic pieces protruding from the surface in the thickness direction of the conductive component 18. For example, a plurality of elastic contacts 19 are provided. The elastic contacts 19 are made of conductive materials. The elastic contacts 19 can effectively contact the edges of the first terminal block 115 and the second terminal block, so that the electromagnetic shielding effect of the conductive component 18 is better.
