DETAILED DESCRIPTION

[0071] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0072] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "inside", "outside" and the like indicate directions or positional relationships based on the directions or relative positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Unless otherwise specified, the above-mentioned directional description can be flexibly set in the process of actual application under the condition that the relative positional relationship shown in the accompanying drawings is satisfied.

[0073] 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 the present invention, unless otherwise specified, "plurality" means two or more.

[0074] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. It can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0075] In the embodiments of the present invention, the terms "comprises", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, article or device including the element.

[0076] In the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0077] In vehicle electronic systems, a controller refers to an electronic unit used to process and manage various functions, and electronic devices are an important part of the controller.

[0078] In the related art, see Figure 1 , Figure 1 The schematic diagram of the structure of an electronic device provided by the related technology, the output terminals 2' of the electronic device 1' are arranged side by side, and holes are separated at the output ends for nut connection. Different electronic devices are electrically connected by nuts in a one-to-one correspondence between output terminals and input terminals.

[0079] However, this electronic device has the problem of poor transmission stability.

[0080] Based on this, see Figure 2 , Figure 2 This is a structural schematic diagram of a vehicle provided in an embodiment of the present application. The embodiment of the present application provides a vehicle 100, which may include a chassis 10, a vehicle body 20, and a controller 30.

[0081] It is understandable that the vehicle 100 may be a fuel vehicle, an electric vehicle, a hybrid vehicle, a gas vehicle, a methanol vehicle, a solar vehicle, etc. For example, the vehicle 100 may be a passenger vehicle such as a sedan, a sport utility vehicle (SUV), a multi-purpose vehicle (MPV), or a bus, a truck, a semi-trailer, etc. This application does not impose any specific restrictions on this.

[0082] The chassis 10 can be installed with a motor and other components of the vehicle 100 to form the overall shape of the vehicle 100, and receive power from the motor to make the vehicle 100 move and ensure normal driving.

[0083] The vehicle body 20 can be mounted on the chassis 10, and a cabin is formed inside the vehicle body 20. The cabin is provided with seats for the driver, passengers, or cargo. It should be noted that when the vehicle 100 is a bus or a car, the vehicle body 20 is generally an integral structure. When the vehicle 100 is a truck, the vehicle body 20 is generally composed of a cab and a cargo box.

[0084] The controller 30 may be mounted on the chassis 10 and is used to manage the stability and handling of the vehicle 100, including functions such as skid control (TCS), electronic stability control (ESP), and wheel drive control (AWD). The controller 30 may also be responsible for the fuel injection, ignition timing, speed, and other parameters of the engine to optimize engine performance, improve fuel efficiency, and reduce emissions. The controller 30 is one of the most critical parts of the vehicle 100.

[0085] It should be noted that the above components are merely examples of some components of the vehicle 100 , and are not limitations on the specific structure of the vehicle 100 .

[0086] In the circuit system of the controller 30, the inductance formed by accident or unintended design is called stray inductance (SI), which is usually caused by the relative position between conductors, wiring layout, packaging design or magnetic field in the surrounding environment. The existence of stray inductance can cause problems such as loss or signal attenuation in the circuit system.

[0087] Based on this, see Figure 3 , Figure 3The exploded structural diagram of a controller 30 provided in an embodiment of the present application is shown, and the controller 30 includes a first electronic device 40, a second electronic device 50, a first connector 60, and a second connector 70. The first electronic device 40 and the second electronic device 50 are stacked. In this way, the structure of the controller 30 is more compact, the connection loop between the first electronic device 40 and the second electronic device 50 is shorter, and the stray inductance generated is smaller. In addition, the controller 30 can realize more functions in a limited space, which is suitable for the needs of miniaturized electronic products.

[0088] In some embodiments, the first connector 60 connects the first external terminal 413 of the first electronic device 40 and the first input terminal 52 of the second electronic device 50. The second connector 70 connects the second external terminal 423 of the first electronic device 40 and the second input terminal 53 of the second electronic device 50. The first connector 60 and the second connector 70 connect the external terminal and the input terminal, respectively, which simplifies the overall circuit connection design, reduces the complexity of wiring, and improves assembly efficiency.

[0089] The first electronic device 40 may be a capacitor. Next, the first electronic device 40 is introduced.

[0090] For details, see Figure 4 as well as Figure 5 , Figure 4 A schematic diagram of the structure of a first electronic device provided in an embodiment of the present application, Figure 5 for Figure 4 A schematic structural diagram of the first electronic device from another angle is shown, wherein: Figure 5 for Figure 4 From an oblique side view, the first electronic device 40 includes a first busbar 41, a second busbar 42 and a body 43. The first busbar 41 includes a first sub-row 411 and a second sub-row 412 connected to the first sub-row 411. The second busbar 42 includes a third sub-row 421 and a fourth sub-row 422 connected to the third sub-row 421. The third sub-row 421 and the first sub-row 411 are arranged opposite and spaced apart. The fourth sub-row 422 and the second sub-row 412 are stacked, at least a portion of the second sub-row 412 forms a first external terminal 413, and at least a portion of the fourth sub-row 422 forms a second external terminal 423.

[0091] In this way, the inductances generated by the current paths in the second sub-row 412 and the fourth sub-row 422 are in opposite directions and cancel each other out, thereby reducing the equivalent inductance formed between the first external terminal 413 and the second external terminal 423 , thereby improving the transmission stability of the first electronic device 40 .

[0092] In addition, this can increase the connection area of ​​the external terminal output by the first electronic device 40, reduce the risk of poor contact, and avoid problems such as current instability, signal loss or noise caused by poor contact.

[0093] The body 43 is disposed between the first sub-row 411 and the third sub-row 421. The positive electrode of the body 43 is connected to the first sub-row 411, and the negative electrode of the body 43 is connected to the third sub-row 421. This arrangement can make the overall structure more compact, reduce the volume, and facilitate the installation of the first electronic device 40.

[0094] In some other embodiments, the cathode of the body 43 is connected to the first sub-row 411 , and the anode of the body 43 is connected to the third sub-row 421 .

[0095] In some embodiments, one of the fourth sub-row 422 and the second sub-row 412 includes a first end 424, and the other has a first edge 414, and the first end 424 is located outside the first edge 414. That is, in the extension direction of the fourth sub-row 422 and the second sub-row 412, the length of the first end 424 is longer than the length of the first edge 414.

[0096] In this way, the extended portion of the second sub-row 412 and the extended portion of the fourth sub-row 422 are staggered, which facilitates the connection of the second sub-row 412 and the fourth sub-row 422 to other components.

[0097] The fourth sub-row 422 includes a first end 424, and the second sub-row 412 has a first edge 414. Alternatively, the second sub-row 412 includes a first end 424, and the fourth sub-row 422 has a first edge 414. This application does not limit this, and will be described specifically according to actual needs.

[0098] For example, see Figure 4 The second sub-row 412 includes a first end 424, and the fourth sub-row 422 has a first edge 414. The first end 424 forms a first external terminal 413 of the first electronic device 40, and the other part where the first edge 414 is located forms a second external terminal 423 of the first electronic device 40.

[0099] In this way, space can be effectively utilized, which helps to reduce the volume of the entire electronic device and improve space utilization.

[0100] In some embodiments, the first end 424 is the end of the second sub-row 412 away from the first sub-row 411 , and the first edge 414 is the edge of the fourth sub-row 422 away from the third sub-row 421 .

[0101] By configuring in this way, the positions of the first end 424 and the first edge 414 are properly arranged, so as to optimize the path of the electrical connection, reduce the connection length, reduce the stray inductance and resistance, and improve the circuit performance.

[0102] In some embodiments, the second sub-row 412 includes a first conductive portion 4121, and the first conductive portion 4121 is located on one side of the body 43. The arrangement direction of the body 43 and the first conductive portion 4121 is orthogonal to the arrangement direction of the first sub-row 411 and the third sub-row 421. The fourth sub-row 422 includes a second conductive portion 4221, and the second conductive portion 4221 is stacked with the first conductive portion 4121.

[0103] In this way, by stacking the first conductive part 4121 and the second conductive part 4221, the stray inductance can be effectively reduced. At the same time, such a design can effectively utilize the limited space, making the overall layout more compact and improving the space efficiency.

[0104] In some embodiments, the first electronic device 40 further includes a fifth sub-row 415 , which is connected between the first sub-row 411 and the first conductive portion 4121 , and is located between the body 43 and the first conductive portion 4121 .

[0105] In this way, by adding the fifth sub-row 415 between the first sub-row 411 and the first conduction part 4121, the first sub-row 411 can be extended and the extension direction of the first sub-row 411 can be changed. In addition, such a setting helps to enhance the stability of the overall structure and provide additional support for the first conduction part 4121, thereby resisting the influence of external forces and improving mechanical strength.

[0106] In some embodiments, the first edge 414 is located at the second conductive portion 4221 , and the first end 424 is an end of the first conductive portion 4121 .

[0107] This simplifies the connections between components, improves assembly efficiency, reduces production complexity, and reduces potential sources of failure.

[0119] The extended length of the first insulating member 44 is greater than or equal to the length of the fourth sub-row 422 , so as to ensure that the end of the fourth sub-row 422 is insulated from the second sub-row 412 .

[0120] The extended length of the first insulating member 44 is smaller than the length of the second sub-row 412 to ensure that a certain area of ​​the connection region is exposed at the end of the second sub-row 412 to facilitate installation and electrical connection.

[0121] The extension length of the first insulating member 44 on both sides is greater than the extension length of the second sub-row 412 and the fourth sub-row 422, that is, the width of the first insulating member 44 is greater than the width of the second sub-row 412 and the fourth sub-row 422 to ensure that the two sides of the second sub-row 412 and the two sides of the fourth sub-row 422 are insulated.

[0127] In this way, the partition 473 can effectively isolate the first accommodating space 471 and the second accommodating space 472. The first electronic device 40 is located in the first accommodating space 471, and other devices are located in the second accommodating space 472, which can prevent electrical signals from interfering with each other and help improve the stability and safety of the equipment.

[0128] In some embodiments, the end of the partition 473 is an insulating end 474.

[0129] In this way, the first electronic device 40 and the partition 473 can be fully insulated, and the relative distance between the first electronic device 40 and the partition 473 can be as small as possible, so that the first electronic device 40 has a compact structure and a small volume.

[0135] For details, see Fig. 9 , Fig. 9 The schematic diagram of the structure of a second electronic device provided in an embodiment of the present application is as follows. The second electronic device 50 includes a main body 51, a first input terminal 52, and a second input terminal 53. The main body 51 includes a middle portion 511 and a second edge 512. The first input terminal 52 is disposed on a side of the second edge 512 away from the middle portion 511. The second input terminal 53 is disposed on a side of the first input terminal 52 away from the second edge 512.

[0136] In this way, the first input terminal 52 and the second input terminal 53 are staggered, which facilitates the connection of the first input terminal 52 and the second input terminal 53 with other devices.

[0138] In some embodiments, the first input terminal 52 is spaced apart from and stacked with the second input terminal 53 along the thickness direction of the body 51 .

[0139] In this way, the first input terminal 52 and the second input terminal 53 are staggered along the thickness direction of the main body 51 , which can shorten the spacing distance between the first input terminal 52 and the second input terminal 53 , thereby reducing stray inductance.

[0144] In some embodiments, the electronic device further includes a heat sink 56, which is connected to the side of the heat sink 55 facing away from the main body 51. In this way, the heat sink 56 provides an additional heat exchange area, which can more effectively discharge the heat absorbed by the heat sink 55 to the environment, thereby improving the heat dissipation capacity of the entire system.

[0145] The heat sink 56 may be arranged in a needle shape. The present application does not limit the number of the heat sink 56, which may be arranged according to actual conditions.

[0146] Exemplarily, there are a plurality of heat sinks 56 , which are arranged in an array on a side of the heat sink 55 that is away from the main body 51 . This facilitates processing.

[0154] The welding method may be laser welding, ultrasonic welding, spot welding, etc. This application does not limit this, and it is specifically configured according to the actual needs.

[0155] In some embodiments, the controller 30 further includes a third insulating member 74 disposed between the first connecting member 60 and the second connecting member 70 .

[0156] In this way, by setting the third insulating member 74, the first connector 60 and the second connector 70 can be fully insulated, so that the relative distance between the first connector 60 and the second connector 70 can be as small as possible, thereby reducing the stray inductance between the first connector 60 and the second connector 70.

[0157] In some other embodiments, an insulating sheet or insulating material may be provided on the side of the second connector 70 facing the first connector 60. This can improve the insulation effect between the first connector 60 and the second connector 70, while preventing the third insulating member 74 from breaking or causing other problems that lead to insulation failure.

[0158] In order to prevent the third insulating member 74 from sliding, glue may be provided on the side of the third insulating member 74 facing the first connecting member to make it adhesive.

Fig.13 A structural schematic diagram of a second connecting member is provided for other embodiments of the present application. In order to enable the first connecting member 60 and the second connecting member 70 to adapt to the first electronic device 40, the first connecting member 60 and the second connecting member 70 are designed in a Z shape, which facilitates the installation and connection of the first connecting member 60 and the second connecting member 70.

[0160] In this way, the first connecting member 60 and the second connecting member 70 can be welded in the same direction, thereby simplifying the processing and improving the processing efficiency.

[0175] In this way, the heat sink 56 is located in the cooling water channel, and can directly dissipate heat efficiently through liquid cooling, thereby enhancing the heat dissipation effect, reducing the temperature of the heat sink 55 and the second electronic device 50, and ensuring that they work within a safe temperature range. In addition, by embedding the heat sink 56 in the cooling water channel, the overall space of the device is saved, making the design more compact without affecting the heat dissipation performance.

[0176] In some embodiments, a packaging material is provided in the mounting groove 811, and the packaging material is filled between the first electronic device 40 and the inner wall surface of the mounting groove 811. The packaging material fills the gap between the mounting groove 811 and the first electronic device 40, and the first electronic device 40 is completely wrapped by the packaging material, so that the first electronic device 40 is packaged in the mounting groove 811.

[0177] In this way, the first electronic device 40 is completely sealed and wrapped by the packaging material, preventing the first electronic device 40 from being damaged due to oxidation.
