Detailed Implementation

[0084] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0085] In related technologies, different components of power distribution integrated components are connected by connecting terminals or cables, resulting in significant spatial obstruction between the components and low space utilization.

[0086] To solve the above-mentioned technical problems, the first aspect of this application provides a power distribution integrated component 100, as shown in Figures 1 and 2, including: a first type of power distribution device 100a, a second type of power distribution device 100b, a dissimilar conductor 120, and a component support 110.

[0088] It is understood that the power distribution integration component 100 of this application includes power distribution devices capable of realizing different power distribution functions, and combines different power distribution devices through dissimilar conductors 120 to achieve specific circuit functions. It should be noted that the power distribution devices in this application are not limited to the two types mentioned above.

[0089] By adopting the above technical solution, this application connects the first type of power distribution device 100a and the second type of power distribution device 100b through the dissimilar conductor 120, and integrates the two types of power distribution devices and the dissimilar conductor 120 in the same component bracket 110, thereby reducing the spatial obstruction between different power distribution devices, thereby reducing the overall volume of the power distribution integrated component 100 and improving space utilization.

[0090] Meanwhile, integrated power distribution devices can reduce the number of wiring harnesses and connectors used for wiring, and improve electromagnetic compatibility (EMC).

[0091] As a specific solution, the dissimilar conductor 120 is connected to the first type of power distribution device 100a and the second type of power distribution device 100b through laser welding, eliminating bolt connection holes, reducing contact resistance at the weld, and reducing line heating and energy loss.

[0092] In some embodiments, the first type of power distribution device 100a includes one of a capacitor 160, a contactor 180, a fuse 170, an inductor, a resistor, and a transformer.

[0093] The second category of power distribution devices 100b includes: capacitors 160, contactors 180, fuses 170, inductors, resistors, and another type of transformer.

[0094] In some embodiments, referring to Figures 2 and 4, the component support 110 has a receiving space 111. Multiple receiving spaces 111 are provided, and the multiple receiving spaces 111 are separated by partitions 112. A first type of power distribution device 100a and a second type of power distribution device 100b are disposed in different receiving spaces 111.

[0095] For example, the component support 110 is made of insulating material such as plastic.

[0096] By adopting this scheme and setting up the accommodating space 111, it is not only beneficial to the positioning and installation of the power distribution components and improves the installation stability of the power distribution components, but also the component bracket 110 can achieve insulation isolation between the various power distribution components.

[0097] In some embodiments, referring to Figures 2, 4, and 5, the dissimilar conductor 120 extends from one receiving space 111 to another receiving space 111. Thus, the dissimilar conductor 120 enables connection between different power distribution devices.

[0098] In some embodiments, referring to Figures 2 and 5, the heteroconductor 120 has: a first connecting portion 120a, a second connecting portion 120b, and an extension portion 120c.

[0099] The first connecting part 120a is configured to connect to the first type of power distribution device 100a; the second connecting part 120b is configured to connect to the second type of power distribution device 100b; and the extension part 120c is connected between the first connecting part 120a and the second connecting part 120b.

[0100] It is understood that the first connecting part 120a and the second connecting part 120b correspond to different receiving spaces 111 to connect the corresponding power distribution devices. Specifically, the first connecting part 120a and the second connecting part 120b are welded to the power distribution devices, resulting in lower contact resistance.

[0101] In some specific embodiments of this application, referring to Figures 2 and 5, the first type of power distribution device 100a includes a capacitor 160, the second type of power distribution device 100b includes a contactor 180, and the dissimilar conductor 120 includes a first conductive bus 121; the first conductive bus 121 has a first connecting portion 120a, a second connecting portion 120b, and an extension portion 120c, wherein the first connecting portion 120a is connected to the contactor 180a, the second connecting portion 120b is connected to a portion of the capacitor 160, and the extension portion 120c extends from a receiving space 111 where the contactor 180a is located to a receiving space 111 where the capacitor 160 is located.

[0102] In some embodiments, referring to FIG4, at least a portion of the extension 120c is embedded within the component support 110.

[0103] It can be understood that the first connecting portion 120a and the second connecting portion 120b in the dissimilar conductor 120 are exposed outside the component support 110, while the extension portion 120c is wrapped inside the component support 110, thus achieving insulation isolation along the extension path of the extension portion 120c.

[0104] Specifically, during the injection molding process, the component bracket 110 embeds the dissimilar conductor 120 into the component bracket to form an insert, so that the same type of conductor and the component form a whole.

[0105] In some embodiments, the power distribution integration assembly 100 further includes a similar conductor (not shown). The similar conductor is mounted on the assembly support 110 and configured to connect at least two first-type power distribution devices 100a.

[0106] For example, similar conductors form a connection between at least two capacitors 160, or between two resistors.

[0107] Specifically, during the injection molding process, the same type of conductor is embedded into the component bracket 110 to form an insert, so that the same type of conductor and the component form a whole.

[0108] In some embodiments, at least a portion of the same type of conductor is embedded within the component support 110. That is, the portion of the same type of conductor that is connected to the power distribution device is exposed outside the component support 110.

[0109] In some embodiments, the power distribution integration assembly 100 further includes a third type of power distribution device 100c.

[0110] The third type of power distribution device 100c is configured to perform the third type of power distribution function; the third type of power distribution device 100c includes one of the following: capacitor 160, contactor 180, fuse 170, inductor, resistor and transformer, and the third type of power distribution device 100c is different from the first type of power distribution device 100a and the second type of power distribution device 100b.

[0111] In some specific embodiments of this application, referring to Figures 2 and 4, the first type of power distribution device 100a includes multiple capacitors 160 installed in the same receiving space 111. The compact arrangement of the capacitors 160 helps to reduce stray inductance. The second type of power distribution device 100b includes multiple contactors 180, each of which is installed in a different receiving space 111. The third type of power distribution device 100c includes a positive fuse 170a and a negative fuse 170b, each of which is installed in a different receiving space 111.

[0112] In some embodiments, referring to Figures 2, 4 and 5, there are multiple dissimilar conductors 120, and the multiple dissimilar conductors 120 are connected to at least two of the first type of power distribution device 100a, the second type of power distribution device 100b and the third type of power distribution device 100c.

[0113] In some specific embodiments of this application, referring to Figures 2, 4, and 5, the dissimilar conductor 120 includes a first conductive bus 121, a second conductive bus 122, a third conductive bus 123, a fourth conductive bus 124, and a fifth conductive bus 125. For ease of distinction, the contactors are labeled 180a, 180b, and 180c from left to right. The first conductive bus 121 connects the first contactor 180a and a portion of the first terminal of the capacitor 160; the second conductive bus 122 connects the second contactor 180b and the positive fuse 170a; the third conductive bus 123 connects the third contactor 180c and the negative fuse 170b; the fourth conductive bus 124 connects the first terminal of another portion of the capacitor 160 and the positive fuse 170a; and the fifth conductive bus 125 connects the second terminals of all the capacitors 160 and the negative fuse 170b. Each conductive bus is welded to its corresponding capacitor 160, contactor 180, and fuse 170.

[0114] In some embodiments, referring to FIG3, capacitor 160 includes: core 163, first connecting core 161 and second connecting core 162.

[0115] The first connecting core 161 is configured to connect to one similar or dissimilar conductor 120; the second connecting core 162 is configured to connect to another similar or dissimilar conductor 120; the core 163 is located between the first connecting core 161 and the second connecting core 162.

[0116] For example, referring to Figures 2, 4, and 5, capacitor 160 is a film capacitor. The first connecting core 161 is connected to either the first conductive bus 121 or the fourth conductive bus 124, and the second connecting core 162 is connected to the fifth conductive bus 125. Three external terminals 124a are provided on one side of the fourth conductive bus 124 as positive output terminals for easy connection to the power module. The fifth conductive bus 125 is also connected to a sixth conductive bus 126, which serves as the negative output terminal connected to the power module.

[0117] In some embodiments, referring to FIG7, the contactor 180 includes a body 183, a power connector 181, and a control connector 182.

[0118] Body 183 includes a coil and contacts. , When the coil is energized, it can generate a magnetic field to drive the contacts to move; the power connector 181 is configured to connect to the access terminal 140; the control connector 182 is configured to connect to the control board 260, so as to facilitate access to the control board 260 for sampling and control. At least a portion of the body 183 (e.g., the coil and contacts) is disposed in the receiving space 111, so that the component support 110 constitutes at least a portion of the housing of the contactor 180.

[0119] In this embodiment, the contactor 180 of this application is a caseless contactor. The bottom and sides of the contactor 180 are protected by the component bracket 110, which can eliminate the need for the outer shell of the contactor 180, save the space occupied, and thus reduce the overall volume of the power distribution integrated component 100.

[0120] In some embodiments, referring to FIG6, the fuse 170 includes a fuse wire 171 and a connection terminal 172.

[0121] At least a portion of the fuse 171 and at least a portion of the connecting terminal 172 are located in the receiving space 111, such that the component support 110 constitutes at least a portion of the housing of the fuse 170. The two ends of the fuse 171 are respectively connected to the connecting terminal 172.

[0122] In this embodiment, the bottom and sides of the fuse 171 are protected by the component bracket 110, which eliminates the need for a housing, saves space, and reduces the overall volume of the power distribution integrated component 100.

[0123] In some embodiments, referring to FIG6, the connection terminal 172 includes a mounting portion 172a and an external portion 172b.

[0124] The mounting portion 172a connects to the end of the fuse 171. The external portion 172b is bent relative to the mounting portion 172a toward the fuse 171, and the external portion 172b is at least configured to connect to a dissimilar conductor 120 to receive or output current.

[0125] For example, the fuse 171 is rectangular in shape, which facilitates its installation into the receiving space 111. The connecting terminals 172 on both sides of the fuse 171 are designed in a C-shape, defined by the bending direction of the external portion 172b. Each mounting portion 172a has four screw holes corresponding to the screw hole positions of the fuse 171. The fuse 171 and the connecting terminals 172 on both sides can be assembled by inserting screws into the screw holes.

[0126] This design of the connection terminal 172 makes the fuse 170 have a symmetrical structure, so there is no need to distinguish the orientation of the fuse 170 during installation. Furthermore, by defining the shape of the connection terminal 172, that is, by bending the outer part 172b of the connection terminal 172 towards the fuse 171, more space is saved compared to an outwardly extending shape, making it easier for the fuse 170 to fit perfectly into the receiving space 111. In addition, the outer part 172b has sufficient area for laser welding, which facilitates the connection of the fuse 170 into the circuit by laser welding.

[0127] In some embodiments, referring to FIG1, the power distribution integration assembly 100 further includes a potting compound 191. The potting compound 191 is configured to pot and cover at least a portion of the first type of power distribution device 100a, at least a portion of the second type of power distribution device 100b, and at least a portion of the dissimilar conductor 120.

[0128] The use of potting compound 191 can fix and encapsulate various power distribution components and dissimilar conductors 120. At the same time, after the dissimilar conductors 120 are injected into the component bracket 110 and potted, the dissimilar conductors 120 are completely insulated from each other, and there is no problem of insufficient electrical clearance. Therefore, the length of dissimilar conductors 120 or similar conductors is reduced.

[0129] Furthermore, through the contact between the potting compound 191 and each power distribution device and the dissimilar conductor 120, the potting compound 191 can effectively conduct heat. Compared with heat radiation heat transfer, the heat conduction efficiency is higher, significantly reducing the temperature of the power distribution integrated component 100, resulting in better heat dissipation. This can reduce the cross-sectional area of ​​the dissimilar conductor 120 or the same type of conductor, and improve the lifespan of the power distribution integrated component 100.

[0130] In addition, after the various power distribution components, dissimilar conductors 120 and similar conductors are integrated, they are fixed in the component bracket 110 with potting compound 191, which improves the resistance to external impacts and vibrations, avoids direct exposure, improves waterproof, dustproof and corrosion-proof effects, and improves the stability and service life of the power distribution integrated component 100.

[0131] In some embodiments, referring to FIG1, the power distribution integrated assembly 100 further includes a baffle 192. The baffle 192 is mounted to the assembly bracket 110 and surrounds the outside of the assembly bracket 110 to define the potting position of the potting compound 191 and prevent the potting compound 191 from overflowing outside the assembly bracket 110.

[0132] According to a second aspect of this application, a motor controller 200 is provided, which includes the aforementioned power distribution integrated component 100. The motor controller 200 possesses all the beneficial effects of the aforementioned power distribution integrated component 100, which will not be elaborated further herein.

[0133] In some embodiments, referring to Figures 8 to 10, the motor controller 200 includes a housing 210. The housing 210 forms an internal space 211; a power distribution integration assembly 100 is disposed in the internal space 211. By employing the power distribution integration assembly 100 described above, the space utilization of the housing 210 of the motor controller 200 is improved.

[0134] In some embodiments, referring to Figures 8 to 10, the housing 210 has a cooling channel for the flow of coolant to transfer heat generated by the power distribution integration assembly 100 and the inverter module 250 of the motor controller 200 to the coolant.

[0135] In some embodiments, referring to Figures 8 and 10, the cooling channel includes at least a first branch 221 and a second branch 222, which are connected in parallel. The coolant flowing through the first branch 221 exchanges heat with the inverter module 250, and the second branch 222 exchanges heat with the power distribution integration assembly 100.

[0136] In some embodiments, referring to Figures 8 and 10, the motor controller 200 further includes: interference flow columns 230. Multiple interference flow columns 230 are provided and disposed within the cooling channel. The number of interference flow columns 230 can be controlled by machining; the more interference flow columns 230 there are, the greater the flow resistance within the channel, and the less coolant flows through the cooling channel 220. As a more specific embodiment, different numbers of interference flow columns 230 or isolation ribs are provided in the first branch channel 221 and the second branch channel 222, which can adjust the ratio of the flow resistance of the first branch channel 221 and the second branch channel 222, thereby achieving the distribution of coolant flow rate within the first branch channel 221 and the second branch channel 222.

[0137] In some embodiments, referring to Figures 8 and 10, the motor controller 200 further includes one or more mounting bosses 240, which communicate with the first branch channel 221 and are configured to connect to the inverter module 250 of the motor controller 200. This allows the coolant to exchange heat with the inverter module 250 as it flows through the first branch channel 221, thereby dissipating heat from the inverter module 250.

[0138] In some embodiments, referring to Figures 8 and 10, the distance between the first branch 221 and the power distribution integration assembly 100 is greater than the distance between the second branch 222 and the power distribution integration assembly 100.

[0139] Specifically, the second branch 222 corresponds to the capacitor 160, and the heat generated by it is transferred to the coolant flowing in the second branch 222 through the potting compound 191 and the component bracket 110, which can achieve heat dissipation; the side wall forming the second branch 222 is adjacent to each power distribution device, similar conductor and dissimilar conductor 120, and the heat generated by these devices when they are working is transferred to the coolant flowing in the second branch 222 through the potting compound 191 and the component bracket 110, which can achieve heat dissipation.

[0140] In some embodiments, referring to FIG11, the motor controller 200 further includes a control board 260. The control board 260 is connected to at least one of the signal terminals of the first type of power distribution device 100a, the signal terminals of the second type of power distribution device 100b, and the sampling terminal 120d of the dissimilar conductor 120.

[0141] For example, the contactor 180 is provided with two control connectors 182 (i.e. signal terminals) on its upper part, which are configured to receive or output signals; the first conductive bar 121 and the second conductive bar 122 extend to form sampling terminals 120d respectively; the control connectors 182 and the sampling terminals 120d pass directly through the control board 260 and form an electrical connection with the control board 260, which reduces the use of wiring harnesses and the space occupied, and the overall structure is compact.

[0142] According to a third aspect of this application, referring to FIG12, a vehicle 1 is provided, which includes the aforementioned power distribution integrated component 100 or motor controller 200. The vehicle 1 possesses all the beneficial effects of the aforementioned power distribution integrated component 100 or motor controller 200, which will not be elaborated further herein.

[0143] The vehicle 1 can be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this application does not make any specific restrictions on it.
