Description

An electric control assembly and a vehicle

[0001] Cross-reference to Related Applications

[0002] The present application is based on and claims priority to Chinese Patent Application No. 202420752375.2, filed on April 11, 2024, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] The present disclosure relates to the technical field of power semiconductor devices, and in particular to an electric control assembly and a vehicle. BACKGROUND

[0004] With the continuous development of social economy, automobiles have become an essential part of people's lives, and electric control assemblies are extremely important components in automobiles. The capacitor in the electric control assembly receives direct current from the battery and outputs to the input end of the power module, which is used to complete the conversion of direct current to alternating current.

[0005] However, in the prior art, the power module and the capacitor are connected and locked by screws, which makes the input end of the power module need to be staggered to avoid interference during installation in order to adapt to the connection method by screws. However, this setting makes the overlapping area between the positive input end and the negative input end of the power module need to be sacrificed for the installation of the screws, resulting in an increase in the equivalent series inductance between the positive input end and the negative input end of the power module, which in turn increases the switching loss of the power module. Moreover, the screw installation method has poor vibration durability and reliability, and the screws may loosen after long-term use, which increases the contact resistance between the power module and the capacitor and increases the thermal risk.

[0051] FIG. 1 is a structural schematic diagram of an electric control assembly provided by an embodiment of the present disclosure, as shown in FIG. 1, the electric control assembly comprises a power module 100 and a capacitor 200. The positive terminal 110 of the power module 100 is welded with the positive terminal 210 of the capacitor 200, and the negative terminal 220 of the power module 100 is welded with the negative terminal 220 of the capacitor 200.

[0052] Specifically, the positive terminal 110 of the power module 100 is connected with the positive terminal 210 of the capacitor 200 in a welding manner, and the negative terminal 120 of the power module 100 is also connected with the negative terminal 220 of the capacitor 200 in a welding manner, so that the contact resistance between the terminals is reduced, thereby reducing the risk of heat. And the vibration durability reliability of each terminal is enhanced, so that the connection between the terminals will not loosen when the electric control assembly is subjected to large vibration or is used for a long time, thereby avoiding the increase of contact resistance caused by poor contact between the terminals, and reducing the risk of temperature anomaly of the electric control assembly.

[0053] Fig. 2 is a structural schematic diagram of a power module provided by an embodiment of the present disclosure. As shown in Fig. 2, the positive terminal 110 and the negative terminal 120 of the power module 100 each include a first horizontal leading portion 111 / 121 parallel to the body 101 of the power module. The main body 1111 / 1211 of the first horizontal leading portion 111 / 121 of the positive terminal 110 and the negative terminal 120 of the power module 100 is at least partially laminated and arranged in intervals.

[0054] It should be noted that the reference sign A in Fig. 2 is a front view of the power module 100, the reference sign B is a top view of the power module 100, and Fig. 2 only exemplarily shows one positive terminal 110 and one negative terminal 120 of the power module 100. The number of the positive terminal 110 and the negative terminal 120 is arranged according to actual conditions, which is not specifically limited herein.

[0055] The laminated area range of the main body 1111 / 1211 of the first horizontal leading portion 111 / 121 of the positive terminal 110 and the negative terminal 120 of the power module 100 is determined according to actual conditions.

[0056] Exemplarily, the main body 1111 / 1211 of the first horizontal leading portion 111 / 121 of the positive terminal 110 and the negative terminal 120 of the power module 100 is partially laminated and arranged in intervals.

[0057] Specifically, the main body 1111 of the first horizontal leading portion 111 of the positive terminal 110 of the power module 100 partially overlaps the main body 1211 of the first horizontal leading portion 121 of the negative terminal 120 of the power module 100 in the projection range in the vertical direction.

[0058] In fact, when the power module 100 and the capacitor 200 are laminated in up-down direction, the extension length of the main body 1111 of the first horizontal leading portion 111 of the positive terminal 110 of the power module 100 in the horizontal direction is greater than the extension length of the main body 1211 of the first horizontal leading portion 121 of the negative terminal 120 of the power module 100 in the horizontal direction. Therefore, in the projection range in the vertical direction, the projection range of the main body 1111 of the first horizontal leading portion 111 of the positive terminal 110 of the power module 100 partially locates outside the projection range of the main body 1211 of the first horizontal leading portion 121 of the negative terminal 120 of the power module 100.

[0059] Of course, it can also be that when the power module 100 and the capacitor 200 are arranged in a vertical stack, the extension length of the main body part 1111 of the first horizontal lead-out part 111 of the positive terminal 110 of the power module 100 in the horizontal direction is less than the extension length of the main body part 1211 of the first horizontal lead-out part 121 of the negative terminal 120 of the power module 100 in the horizontal direction. Thereby, in the projection range in the vertical direction, the projection range of the main body part 1211 of the first horizontal lead-out part 121 of the negative terminal 120 of the power module 100 partially exists outside the projection range of the main body part 1111 of the first horizontal lead-out part 111 of the positive terminal 110 of the power module 100.

[0060] Exemplarily, the main body parts 1111 / 1211 of the first horizontal lead-out parts 111 / 121 of the positive terminal 110 and the negative terminal 120 of the power module are completely stacked and arranged with a spacing. In fact, it can be that when the power module 100 and the capacitor 200 are arranged horizontally, the extension length of the main body part 1111 of the first horizontal lead-out part 111 of the positive terminal 110 of the power module 100 in the horizontal direction is equal to the extension length of the main body part 1211 of the first horizontal lead-out part 121 of the negative terminal 120 of the power module 100 in the horizontal direction. Thereby, in the projection range in the vertical direction, the projection range of the main body part 1111 of the first horizontal lead-out part 111 of the positive terminal 110 of the power module 100 is the same as the projection range of the main body part 1211 of the first horizontal lead-out part 121 of the negative terminal 120 of the power module 100, and the projection ranges of the two completely overlap.

[0061] Specifically, since the positive terminal 110 of the power module 100 and the positive terminal 210 of the capacitor 200 are connected in a welding manner, and the negative terminal 120 of the power module 100 and the negative terminal 220 of the capacitor are connected in a welding manner, the positive and negative terminals of the power module do not need to be staggered to avoid the installation of screws, and thus the main body 1111 of the first horizontal lead-out part 111 of the positive terminal 110 of the power module 100 and the main body 1211 of the first horizontal lead-out part 121 of the negative terminal 120 of the power module 100 are completely overlapped in the vertical direction, and thus the main body 1111 / 1211 of the first horizontal lead-out part 111 / 121 of the positive and negative terminals 110 / 120 of the power module can be completely laminated. When the positive terminal 110 and the negative terminal 120 of the power module 100 have current flowing therethrough, opposite magnetic fields are generated. According to the present disclosure, the main body 1111 of the first horizontal lead-out part 111 of the positive terminal 110 of the power module 100 and the main body 1211 of the first horizontal lead-out part 121 of the negative terminal 120 of the power module 100 are completely laminated, so that more magnetic fields between them can be cancelled out, thereby effectively reducing the equivalent series inductance between the positive terminal 110 and the negative terminal 120 of the power module 100. Since the current flowing through the power module 100 does not change during the opening and closing process of the power module 100, when the equivalent series inductance is reduced, the switching loss of the power module 100 is also reduced, thereby improving the working efficiency of the power module 100. In addition, since the power module 100 and the capacitor are connected in a welding manner, the positive terminal 110 and the negative terminal 120 of the power module 100 no longer need to be provided with through holes for installing screws, further increasing the lamination area between the main body 1111 / 1211 of the first horizontal lead-out part 111 / 121 of the positive terminal 110 and the negative terminal 120 of the power module 100, reducing the equivalent series inductance between the positive terminal 110 and the negative terminal 120 of the power module 100, reducing the switching loss of the power module 100, and thereby improving the working efficiency of the power module 100.

[0062] In some embodiments, FIG. 3 is a schematic diagram of a capacitor structure provided by an embodiment of the present disclosure. As shown in FIG. 3, the positive terminal 210 and the negative terminal 220 of the capacitor 200 respectively include a second horizontal lead-out part 211 / 221 parallel to the capacitor body 201; and the main body 2111 / 2211 of the second horizontal lead-out part 211 / 221 of the positive terminal 210 and the negative terminal 220 of the capacitor 200 is at least partially laminated and spaced.

[0063] It should be noted that the reference sign C in FIG. 3 is a front view of the capacitor 200, the reference sign D is a top view of the capacitor 200, and FIG. 3 only exemplarily shows one positive terminal 210 and one negative terminal 220 of the capacitor 200, and the number of the positive terminal 210 and the negative terminal 220 is set according to actual conditions, which is not specifically limited herein.

[0064] The range of the lamination area of the main body part 2111 / 2211 of the second horizontal lead-out part 211 / 221 of the positive terminal 210 and the negative terminal 220 of the capacitor 200 is determined according to actual conditions.

[0065] Exemplarily, part of the area of the main body part 2111 / 2211 of the second horizontal lead-out part 211 / 221 of the positive terminal 210 and the negative terminal 220 of the capacitor 200 is laminated and arranged at intervals.

[0066] Specifically, the projection part of the area of the main body part 2111 of the second horizontal lead-out part 211 of the positive terminal 210 of the capacitor 200 overlaps with the main body part 2211 of the second horizontal lead-out part 221 of the negative terminal 220 of the capacitor 200 in the vertical direction.

[0067] In fact, when the power module 100 and the capacitor 200 are arranged in a stacked manner, the extension length of the main body part 2111 of the second horizontal lead-out part 211 of the positive terminal 210 of the capacitor 200 along the horizontal direction is greater than the extension length of the main body part 2211 of the second horizontal lead-out part 221 of the negative terminal 220 of the capacitor 200 along the horizontal direction. Therefore, in the projection range in the vertical direction, the projection range of the main body part 2111 of the second horizontal lead-out part 211 of the positive terminal 210 of the capacitor 200 is partially located outside the projection range of the main body part 2211 of the second horizontal lead-out part 221 of the negative terminal 220 of the capacitor 200.

[0068] Of course, when the power module 100 and the capacitor 200 are arranged in a stacked manner, the extension length of the main body part 2111 of the second horizontal lead-out part 211 of the positive terminal 210 of the capacitor 200 along the horizontal direction can be less than the extension length of the main body part 2211 of the second horizontal lead-out part 221 of the negative terminal 220 of the capacitor 200 along the horizontal direction. Therefore, in the projection range in the vertical direction, the projection range of the main body part 2211 of the second horizontal lead-out part 221 of the negative terminal 220 of the capacitor 200 is partially located outside the projection range of the main body part 2111 of the second horizontal lead-out part 211 of the positive terminal 210 of the capacitor 200.

[0069] Exemplarily, the main body part 2111 / 2211 of the second horizontal lead-out part 211 / 221 of the positive terminal 210 and the negative terminal 220 of the capacitor 200 is completely laminated and arranged at intervals.

[0070] In fact, when the power module 100 and the capacitor 200 are arranged horizontally, the extension length of the main body part 2111 of the second horizontal lead-out part 211 of the positive terminal 210 of the capacitor 200 in the horizontal direction is equal to the extension length of the main body part 2211 of the second horizontal lead-out part 221 of the negative terminal 220 of the capacitor 200 in the horizontal direction. Thus, in the projection range in the vertical direction, the projection range of the main body part 2111 of the second horizontal lead-out part 211 of the positive terminal 210 of the capacitor 200 is the same as the projection range of the main body part 2211 of the second horizontal lead-out part 221 of the negative terminal 220 of the capacitor 200, and the projection ranges of the two completely overlap.

[0071] Specifically, since the positive terminal 210 of the capacitor 200 is connected to the positive terminal of the power module by welding, and the negative terminal 220 of the capacitor 200 is connected to the negative terminal of the power module by welding, the positive and negative terminals of the capacitor do not need to be staggered to avoid installation screws, and thus the main body part 2111 of the first horizontal lead-out part 211 of the positive terminal 210 of the capacitor 200 and the main body part 2211 of the first horizontal lead-out part 221 of the negative terminal 220 of the capacitor 200 can be completely stacked, thereby effectively reducing the equivalent series inductance between the positive terminal 210 and the negative terminal 220 of the capacitor 200. Moreover, since the capacitor 200 is connected to the power module by welding, the positive terminal 210 and the negative terminal 220 of the capacitor 200 no longer need to be provided with through holes for installing screws, further increasing the stacking area between the main body parts 2111 / 2211 of the first horizontal lead-out parts 211 / 221 of the positive terminal 210 and the negative terminal 220 of the capacitor 200, and reducing the equivalent series inductance between the positive terminal 210 and the negative terminal 220 of the capacitor 200.

[0072] In some embodiments, the power module and the capacitor are arranged in a stacked manner.

[0073] For example, the power module is arranged above the capacitor, and the projection of the power module in the vertical direction coincides with the projection of the capacitor in the vertical direction, so that the power module and the capacitor are arranged in a stacked manner. Arranging the power module and the capacitor in a stacked manner can make the space occupied by the electric control assembly in the horizontal direction smaller, and can effectively meet the compact design requirement of the electric control assembly in the horizontal direction.

[0074] At least one of the positive terminal and the negative terminal of the power module includes a first vertical part arranged at the free end of the first horizontal lead-out part; at least one of the positive terminal and the negative terminal of the capacitor includes a second vertical part arranged at the free end of the second horizontal lead-out part; and the first vertical part and the second vertical part with the same polarity are welded.

[0075] Specifically, when the power module and the capacitor module are arranged in a stacked manner, the terminals of a certain polarity are necessarily located at the inner side during welding, and the positive and negative terminals of the power module and the positive and negative terminals of the capacitor should ensure that the terminals on the outer side do not interfere with the welding process between the terminals on the inner side. Therefore, the terminals can be contacted in the vertical direction to complete welding by arranging the first vertical part on the positive and negative terminals of the power module and the second vertical part on the positive and negative terminals of the capacitor, and the terminals on the outer side can be kept away from the terminals on the inner side during welding by arranging or not arranging the first vertical part and the second vertical part or adjusting the length of the first vertical part and the second vertical part, thereby reducing the complexity of the welding process and improving the production efficiency.

[0076] In some embodiments, FIG. 4 is a schematic diagram of another electric control assembly structure provided by the embodiments of the present disclosure, as shown in FIG. 4, the electric control assembly further comprises at least a first L-shaped adapter strip.

[0077] The first outer side polarity terminal of the power module 100 away from the capacitor 200 only comprises a first horizontal lead-out part 1311; the first arm part 301 of the first L-shaped adapter strip is welded with the first horizontal lead-out part 1311 of the first outer side polarity terminal; the second outer side polarity terminal of the capacitor 200 away from the power module 100 comprises a second vertical part 2322; the second arm part 302 of the first L-shaped adapter strip is welded with the second vertical part 2322 of the second outer side polarity terminal.

[0078] Specifically, the first outer side polarity terminal of the power module 100 away from the capacitor 200 comprises a first horizontal lead-out part 131, the second outer side polarity terminal of the capacitor 200 away from the power module 100 comprises a second horizontal lead-out part 2321 and a second vertical part 2322, the second vertical part 2322 of the second outer side polarity terminal is arranged at the free end of the second horizontal lead-out part 2321 of the second outer side polarity terminal, and the length of the second vertical part 2322 of the second outer side polarity terminal is arranged relative to the standard of the inner side polarity terminal exposed. Thus, the avoidance of the inner side polarity terminal by the second vertical part 2322 of the second outer side polarity terminal can be achieved, and the welding of the inner side polarity terminal by the outer side polarity terminal during welding can be avoided.

[0079] The first inner side polarity terminal is arranged on the side of the power module 100 close to the capacitor 200, and the second inner side polarity terminal is arranged on the side of the capacitor 200 close to the power module 100. In the welding process, the welding between the first inner side polarity terminal and the second inner side polarity terminal is first completed, and then the welding between the first horizontal leading part 1311 of the first outer side polarity terminal and the second vertical part 2322 of the second outer side polarity terminal is completed by using the first L-shaped adapter strip, so as to conduct the first outer side polarity terminal and the second outer side polarity terminal. By welding the inner side polarity terminal first and then welding the outer side polarity terminal by using the first L-shaped adapter strip, the outer side polarity terminal can be welded while avoiding the welding of the inner side polarity terminal.

[0080] In some embodiments, FIG. 5 is another schematic diagram of an electric control assembly according to an embodiment of the present disclosure. As shown in FIG. 5, the electric control assembly further comprises at least a first I-shaped adapter strip 400; the first outer side polarity terminal of the power module 100 away from the capacitor 200 comprises a first vertical part 1312; the first end of the first I-shaped adapter strip 400 is welded to the first vertical part 1312 of the first outer side polarity terminal; the second outer side polarity terminal of the capacitor 200 away from the power module 100 comprises a second vertical part 2322; and the second end of the first I-shaped adapter strip 400 is welded to the second vertical part 2322 of the second outer side polarity terminal.

[0081] Specifically, the first outer side polarity terminal of the power module 100 away from the capacitor 200 comprises a first horizontal leading part 1311 and a first vertical part 1312, and the first vertical part 1312 of the first outer side polarity terminal is arranged at the free end of the first horizontal leading part 1311 of the first outer side polarity terminal; the second outer side polarity terminal of the capacitor 200 away from the power module 100 comprises a second horizontal leading part 2321 and a second vertical part 2322, and the second vertical part 2322 of the second outer side polarity terminal is arranged at the free end of the second horizontal leading part 2321 of the second outer side polarity terminal. The free end of the first vertical part 132 and the free end of the second vertical part 232 have a certain interval, which can expose the inner side polarity terminal, thereby avoiding the interference of the outer side polarity terminal with the welding of the inner side polarity terminal in the welding process.

[0082] The first inner side polarity terminal of the power module 100 is arranged on the side close to the capacitor 200, and the second inner side polarity terminal of the capacitor 200 is arranged on the side close to the power module 100. In the welding process, the welding between the first inner side polarity terminal and the second inner side polarity terminal is completed first, and then the welding between the first vertical part 1312 of the first outer side polarity terminal and the second vertical part 2322 of the second outer side polarity terminal is completed by using the first I-shaped adapter row 400, so as to conduct the first outer side polarity terminal and the second outer side polarity terminal. By welding the inner side polarity terminal first and then welding the outer side polarity terminal by using the first I-shaped adapter row, the outer side polarity terminal can be welded while avoiding the inner side polarity terminal.

[0083] Continuing to refer to FIGS. 4 and 5, in some embodiments, the first inner side polarity terminal of the power module 100 close to the capacitor 200 includes a first vertical part 1322, and the second inner side polarity terminal of the capacitor 200 close to the power module 100 includes a second vertical part 2312. The first vertical part 1322 of the first inner side polarity terminal and the second vertical part 2312 of the second inner side polarity terminal are welded.

[0084] Specifically, the first inner side polarity terminal of the power module 100 close to the capacitor 200 includes a first horizontal leading part 1321 and a first vertical part 1322, and the first vertical part 1322 of the first inner side polarity terminal is arranged at the free end of the first horizontal leading part 1321 of the first inner side polarity terminal. The second inner side polarity terminal of the capacitor 200 close to the power module 100 includes a second horizontal leading part 2311 and a second vertical part 2312, and the second vertical part 2312 of the second inner side polarity terminal is arranged at the free end of the second horizontal leading part 2311 of the second inner side polarity terminal. When the power module 100 and the capacitor module 200 are arranged in a stacked manner, the first vertical part 1322 of the first inner side polarity terminal of the power module 100 and the second vertical part 2312 of the second inner side polarity terminal of the capacitor 200 can be arranged to ensure that the inner side polarity terminals can be contacted in the vertical direction to complete the welding.

[0085] In some embodiments, FIG. 6 is a schematic structural diagram of another electric control assembly provided by an embodiment of the present disclosure, in which the power module 100 and the capacitor 200 are arranged horizontally in a staggered manner.

[0086] The first horizontal leading part 111 of the positive terminal of the power module 100 is welded with the second horizontal leading part 211 of the positive terminal of the capacitor 200, and the first horizontal leading part 121 of the negative terminal of the power module 100 is welded with the second horizontal leading part 221 of the negative terminal of the capacitor 200.

[0087] Specifically, the horizontal arrangement of the power module 100 and the capacitor 200 can make the electric control assembly occupy less space in the vertical direction, and can make the power module 100 and the capacitor 200 be misaligned according to the position difference between the corresponding polarity terminals, so that the corresponding polarity terminals can be in contact, thereby avoiding the long-time stress between the polarity terminals and causing the terminal damage. In addition, the first horizontal lead-out part 111 of the positive terminal of the power module 100 is welded with the second horizontal lead-out part 211 of the positive terminal of the capacitor 200, and the first horizontal lead-out part 121 of the negative terminal of the power module 100 is welded with the second horizontal lead-out part 221 of the negative terminal of the capacitor 200, so that the positive and negative terminals of the power module 100 do not need to be misaligned to avoid the installation screw, and thus the first horizontal lead-out part 111 of the positive terminal of the power module 100 and the first horizontal lead-out part 121 of the negative terminal of the power module 100 can be completely stacked. The positive terminal and the negative terminal of the power module 100 generate magnetic fields in opposite directions when current flows through, and the disclosure completely stacks the first horizontal lead-out part 111 of the positive terminal of the power module 100 and the first horizontal lead-out part 121 of the negative terminal of the power module 100, so that more magnetic fields between them can be canceled out, thereby effectively reducing the equivalent series inductance between the positive terminal and the negative terminal of the power module 100. In addition, during the opening and closing process of the power module 100, the current passing through is unchanged, so when the equivalent series inductance is reduced, the switching loss of the power module 100 is also reduced, thereby improving the working efficiency of the power module 100. Moreover, since the power module 100 and the capacitor 200 are connected by welding, the positive terminal and the negative terminal of the power module 100 no longer need to be provided with through holes for installing screws, further increasing the stacking area between the first horizontal lead-out parts 111 / 121 of the positive terminal and the negative terminal of the power module 100, reducing the equivalent series inductance between the positive terminal and the negative terminal of the power module 100, reducing the switching loss of the power module 100, and thereby improving the working efficiency of the power module 100.

[0088] In some embodiments, FIG. 7 is a structural schematic diagram of a positive terminal and a negative terminal of a power module provided by an embodiment of the disclosure, as shown in FIG. 7, the electric control assembly further includes an insulating spacer 130; the insulating spacer 130 is clamped between the first horizontal lead-out part 111 of the positive terminal 110 and the first horizontal lead-out part 121 of the negative terminal 120.

[0089] Specifically, reference A in FIG. 7 is a side view of the positive terminal and the negative terminal of the power module, and reference B is a top view of the positive terminal and the negative terminal of the power module. By arranging the insulating spacer 130 between the first horizontal lead-out portion 111 of the positive terminal 110 and the first horizontal lead-out portion 121 of the negative terminal 120, short circuit between the first horizontal lead-out portion 111 of the positive terminal 110 and the first horizontal lead-out portion 121 of the negative terminal 120 can be avoided, and thus damage to the power module can be avoided.

[0090] In some embodiments, continuing to refer to FIG. 7, the positive terminal 110 and the negative terminal 120 of the power module further include contact portions arranged away from the free ends of the first horizontal lead-out portions; the contact portion 114 of the positive terminal 110 of the power module is staggered with the contact portion 124 of the negative terminal 120 of the power module.

[0091] Specifically, the positive terminal 110 of the power module is electrically connected to the power module through the contact portion 114 of the positive terminal 110 of the power module, the negative terminal 120 of the power module is electrically connected to the power module through the contact portion 124 of the negative terminal 120 of the power module, and the contact portion 114 of the positive terminal 110 of the power module is staggered with the contact portion 124 of the negative terminal 120 of the power module, which can effectively avoid short circuit between the positive terminal 110 of the power module and the negative terminal 120 of the power module, and thus damage to the power module can be avoided.
