[0070] The technical solutions of the embodiments of this disclosure 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 disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0071] In the description of this disclosure, it should be understood that the terms "upper," "lower," "left," "right," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or relative positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this disclosure and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. Unless otherwise specified, the above-mentioned orientational descriptions can be flexibly set in practical applications, provided that the relative positional relationships shown in the accompanying drawings are satisfied.

[0072] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0073] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "communication" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a direct connection or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0074] In embodiments of this disclosure, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, article, or apparatus that includes that element.

[0075] In this disclosure, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Rather, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0076] In vehicle electronic systems, the controller refers to the electronic unit used to process and manage various functions, and electronic devices are an important component of the controller.

[0077] In related technologies, referring to Figure 1, multiple output terminals 2A of electronic device 1A are arranged side by side in the left-right direction, and openings are provided at the output ends for nut connection. Different electronic devices are electrically connected to each other by means of nuts, with one-to-one correspondence between output terminals and input terminals.

[0078] However, this electronic device suffers from poor transmission stability.

[0079] Based on this, referring to Figure 2, some embodiments of this disclosure provide a vehicle 100, which may include a chassis 10, a body 20, and a controller 30.

[0080] It is understood that the vehicle 100 can be a gasoline-powered vehicle, an electric vehicle, a hybrid vehicle, a natural gas vehicle, a methanol vehicle, or a solar-powered vehicle, etc. For example, the vehicle 100 can be a passenger car such as a sedan, a sport utility vehicle (SUV), or a multi-purpose vehicle (MPV), or it can be a bus, a truck, or a semi-trailer, etc. This disclosure does not impose any limitations in this regard.

[0081] In some embodiments, the chassis 10 may mount 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 enable the vehicle 100 to move and ensure normal driving.

[0082] The vehicle body 20 can be mounted on the chassis 10. The interior of the vehicle body 20 forms a cabin, which includes seats for the driver, passengers, or cargo. It should be noted that when the vehicle 100 is a passenger car or sedan, its vehicle body 20 is generally a single-piece structure. When the vehicle 100 is a truck, its vehicle body 20 generally consists of a cab and a cargo box.

[0083] The controller 30 can be mounted on the chassis 10. The controller 30 manages the stability and handling of the vehicle 100, including functions such as Traction Control System (TCS), Electronic Stability Program (ESP), and All-Wheel Drive (AWD). The controller 30 is also responsible for controlling engine fuel injection, ignition timing, speed, and other parameters to optimize engine performance, improve fuel efficiency, and reduce emissions. The controller 30 is one of the most critical components of the vehicle 100.

[0084] It should be noted that the above-mentioned components are examples of some components of vehicle 100, and are not a limitation on the structure of vehicle 100.

[0085] In the circuit system of controller 30, inductance that is formed accidentally or unintended is called stray inductance (SI). Stray inductance is usually generated by the relative position between conductors, wiring layout, package design, or magnetic fields in the surrounding environment. The presence of stray inductance can cause problems such as circuit loss or signal attenuation in the circuit system.

[0086] Based on this, referring to Figure 3, 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. This makes the controller 30 more compact, shortens the connection loop between the first electronic device 40 and the second electronic device 50, and reduces stray inductance. Furthermore, the controller 30 can perform more functions within a limited space, making it suitable for the needs of miniaturized electronic products.

[0087] In some embodiments, referring to Figures 3, 4, and 9, the first connector 60 connects to 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 to 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, respectively connecting the external terminal and the input terminal, simplify the overall circuit connection design, reduce wiring complexity, and improve assembly efficiency.

[0088] For example, the first electronic device 40 can be a capacitor. The first electronic device 40 will be described below.

[0089] Referring to Figures 4 and 5, Figure 5 is a perspective view of the first electronic device 40 in Figure 4. 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-busbar 411 and a second sub-busbar 412 connected to the first sub-busbar 411. The second busbar 42 includes a third sub-busbar 421 and a fourth sub-busbar 422 connected to the third sub-busbar 421. The third sub-busbar 421 and the first sub-busbar 411 are arranged opposite to each other and spaced apart. The fourth sub-busbar 422 and the second sub-busbar 412 are stacked, with at least a portion of the second sub-busbar 412 forming a first external terminal 413 and at least a portion of the fourth sub-busbar 422 forming a second external terminal 423.

[0090] In this way, the inductance generated by the current lines in the second sub-row 412 and the fourth sub-row 422 are in opposite directions and cancel each other out, 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.

[0091] In addition, this can increase the connection area of ​​the external terminals of the first electronic device 40, reduce the risk of poor contact, and avoid problems such as unstable current, signal loss or noise caused by poor contact.

[0092] The main body 43 is located between the first sub-row 411 and the third sub-row 421. The positive terminal of the main body 43 is connected to the first sub-row 411, and the negative terminal of the main body 43 is connected to the third sub-row 421. This arrangement makes the overall structure more compact, reduces the size, and facilitates the installation of the first electronic device 40.

[0093] In some other embodiments, the negative terminal of the body 43 is connected to the first sub-row 411, and the positive terminal of the body 43 is connected to the third sub-row 421.

[0094] In some embodiments, one of the fourth sub-row 422 and the second sub-row 412 includes a preset end 424, and the other has a first edge 414, with the preset end 424 located outside the first edge 414. That is, in the extending direction of the fourth sub-row 422 and the second sub-row 412, the length of the preset end 424 is longer than the length of the first edge 414.

[0095] In this way, the extensions of the second sub-row 412 and the fourth sub-row 422 are staggered, which makes it easier for the second sub-row 412 and the fourth sub-row 422 to be connected to other components.

[0096] In some embodiments, the fourth sub-row 422 includes a predetermined end 424, and the second sub-row 412 has a first edge 414. Alternatively, the second sub-row 412 may include a predetermined end 424, and the fourth sub-row 422 may have a first edge 414. This disclosure does not limit the scope of the invention and may be described as needed.

[0097] For example, continuing to refer to FIG4, the second sub-row 412 includes a preset end 424, and the fourth sub-row 422 has a first edge 414. The preset end 424 forms a first external terminal 413 of the first electronic device 40, and the portion of the other part where the first edge 414 is located forms a second external terminal 423 of the first electronic device 40.

[0098] This allows for efficient use of space, helps reduce the overall size of electronic devices, and improves space utilization.

[0099] In some embodiments, the preset 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.

[0100] This configuration, by rationally arranging the positions of the preset end 424 and the first edge 414, can optimize the electrical connection path, reduce connection length, decrease stray inductance and resistance, and improve circuit performance.

[0101] In some embodiments, referring to Figures 4 and 5, the second sub-row 412 includes a first conductive portion 4121, which 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, which is stacked with the first conductive portion 4121.

[0102] In this way, by stacking the first conductive portion 4121 and the second conductive portion 4221, stray inductance can be effectively reduced. In addition, this design can make effective use of limited space, making the overall layout more compact and improving space efficiency.

[0103] 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.

[0104] In this way, by adding a fifth sub-row 415 between the first sub-row 411 and the first conductive part 4121, the first sub-row 411 can be extended, changing the direction of extension of the first sub-row 411. In addition, this arrangement helps to enhance the stability of the overall structure, provides additional support for the first conductive part 4121, thereby resisting the influence of external forces and improving mechanical strength.

[0105] In some embodiments, the first edge 414 is located in the second conductive portion 4221, and the preset end 424 is the end of the first conductive portion 4121.

[0106] This simplifies the connections between components, improves assembly efficiency, reduces production complexity, and minimizes potential sources of failure.

[0107] In some other embodiments, referring to FIG6, the second sub-row 412 has a first edge 414 and the fourth sub-row 422 includes a preset end 424.

[0108] Referring to Figure 6, the second sub-row 412 further includes a third conductive portion 4122, which is connected to and intersects with the first conductive portion 4121. The fourth sub-row 422 further includes a fourth conductive portion 4222, which is connected to and intersects with the second conductive portion 4221. The fourth conductive portion 4222 and the third conductive portion 4122 are stacked. The preset end 424 is the end of the fourth conductive portion 4222, and the first edge 414 is located in the third conductive portion 4122. In this way, by setting the third conductive portion 4122 and the fourth conductive portion 4222, the position and angle of the preset end 424 and the first edge 414 can be changed, which can adapt to different processing and usage scenarios. During the processing, electronic devices can be processed at the same workstation, simplifying the processing process and improving processing efficiency.

[0109] This disclosure does not limit the angle at which the third conductive portion 4122 intersects with the first conductive portion 4121, or the angle at which the fourth conductive portion 4222 intersects with the second conductive portion 4221.

[0110] For example, the angle between the third conductive portion 4122 and the first conductive portion 4121 is 90°, and the angle between the fourth conductive portion 4222 and the second conductive portion 4221 is 90°. This facilitates processing, allows the processing device to operate on the same side, and improves processing efficiency.

[0111] In some embodiments, referring to FIG6, the first insulating member 44 includes a first insulating portion 441 and a second insulating portion 442.

[0112] The first insulating portion 441 is disposed between the second sub-row 412 and the fourth sub-row 422. The second insulating portion 442 intersects with the first insulating portion 441 and is located between the predetermined end 424 and the first edge 414.

[0113] In this way, by setting the second insulating part 442, the preset end 424 and the first edge 414 can be completely insulated, reducing the problem of high voltage arcing.

[0114] For example, the shape of the second insulating portion 442 can be a flat plate, a curved plate, or other irregular shapes. This disclosure does not limit this, and the shape of the second insulating portion 442 can be set according to the actual needs.

[0115] For example, continuing to refer to Figure 6, the second insulating portion 442 is in the shape of a planar plate and is arranged perpendicularly to the first insulating portion 441. This reduces the height of the second insulating portion 442, making the overall structure of the electronic device more compact.

[0116] In some embodiments, continuing to refer to FIG4, the first electronic device 40 further includes a first insulating member 44, which is disposed between the second sub-row 412 and the fourth sub-row 422.

[0117] This ensures that the second sub-row 412 and the fourth sub-row 422 are sufficiently insulated, which allows the relative distance between the second sub-row 412 and the fourth sub-row 422 to be as small as possible, so that the magnetic fields generated by the second sub-row 412 and the fourth sub-row 422 can be canceled out as much as possible, thereby further reducing stray inductance.

[0118] In some embodiments, the extension length of the first insulating member 44 is greater than or equal to the length of the fourth sub-row 422 to ensure that the end of the fourth sub-row 422 is insulated from the second sub-row 412.

[0119] The extension length of the first insulating member 44 is less than the length of the second sub-row 412, so as to ensure that the end of the second sub-row 412 exposes a certain area of ​​connection area, which is convenient for installation and electrical connection.

[0120] The first insulating member 44 extends beyond the second sub-row 412 and the fourth sub-row 422 on both sides, meaning 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 insulation on both sides of the second sub-row 412 and the fourth sub-row 422.

[0121] In some embodiments, continuing to refer to FIG5, the first electronic device 40 further includes a first connection terminal 45 and a second connection terminal 46. The first connection terminal 45 is connected to the positive terminal of the body 43. The second connection terminal 46 is connected to the negative terminal of the body 43.

[0122] In this way, the first connection terminal 45 and the second connection terminal 46 are connected to a DC power supply or an AC power supply, and the current is transmitted to the positive and negative terminals of the body 43.

[0123] In some embodiments, referring to FIG7, the first electronic device 40 further includes a housing 47, the housing 47 including a first receiving space 471, and the first electronic device 40 including an electronic device body, the electronic device body being housed in the first receiving space 471.

[0124] In this way, the housing 47 can protect the first electronic device 40 from dust and moisture entering and causing damage to the first electronic device 40.

[0125] In some embodiments, referring to Figures 7 and 8, a partition 473 is provided inside the housing 47, a first receiving space 471 is located on one side of the partition 473, a second receiving space 472 is provided on the other side of the partition 473, and a first external terminal 413 and a second external terminal 423 are located in the second receiving space 472.

[0126] In this way, the partition 473 can effectively isolate the first accommodating space 471 and the second accommodating space 472. The main body of the first electronic device is located in the first accommodating space 471, and other devices are located in the second accommodating space 472. This can prevent interference between electrical signals and help improve the stability and reliability of the equipment.

[0127] In some embodiments, the end of the partition 473 is an insulating end 474.

[0128] In this way, sufficient insulation can be achieved between the first electronic device 40 and the partition 473, and the relative distance between the first electronic device 40 and the partition 473 can be minimized, making the structure of the first electronic device 40 compact and its size small.

[0129] For example, the insulating end 474 can be an insulating strip, coated with insulating material, or mounted with an insulating block, etc. This disclosure does not limit this.

[0130] In some embodiments, the first accommodating space 471 is provided with encapsulation material, which fills the space between the first electronic device body and the inner wall of the housing 47 and the partition 473.

[0131] In this way, the main body of the first electronic device is fixed within the first accommodating space 471 by the encapsulation material, resulting in a stable structure and high mechanical strength. Furthermore, the first electronic device 40 can dissipate heat directly through the encapsulation material and the housing 47, leading to better heat dissipation.

[0132] For example, the encapsulation material can be epoxy resin, polyester resin, silicone, etc.

[0133] The second electronic device 50 can be a power component. The second electronic device 50 will be described below.

[0134] Referring to FIG9, the second electronic device 50 includes a body 51, a first input terminal 52, and a second input terminal 53. The body 51 includes a middle portion 511 and a second edge 512. The first input terminal 52 is located on the side of the second edge 512 opposite to the middle portion 511. The second input terminal 53 is located on the side of the first input terminal 52 near the second edge 512.

[0135] In this way, the first input terminal 52 and the second input terminal 53 are misaligned, which facilitates the connection of the first input terminal 52 and the second input terminal 53 to other devices.

[0136] For example, the number of the first input terminal 52 and the second input terminal 53 can be 3, 6, 9, etc. This disclosure does not limit this, and the number of the first input terminal 52 and the second input terminal 53 can be set according to actual needs.

[0137] In some embodiments, the first input terminal 52 is spaced apart from the second input terminal 53 along the thickness direction of the body 51 and is stacked.

[0138] 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 distance between the first input terminal 52 and the second input terminal 53, thereby reducing stray inductance.

[0139] In some embodiments, the second electronic device 50 further includes a second insulating member 54 disposed between the first input terminal 52 and the second input terminal 53.

[0140] This allows for sufficient insulation between the first input terminal 52 and the second input terminal 53, minimizing the relative distance between them, shortening the connection loop, and thus reducing stray inductance.

[0141] In some embodiments, the second electronic device 50 further includes a heat sink 55, which is stacked with the main body 51.

[0142] In this way, the heat sink 55 can effectively absorb the heat generated by the second electronic device 50 during operation and quickly conduct it away, reducing the operating temperature of the second electronic device 50. The stacked design can form a larger contact area, improve heat conduction performance, and increase heat dissipation efficiency.

[0143] In some embodiments, the electronic device further includes a heat sink 56 connected to the side of the heat sink 55 facing away from the main body 51. In this way, the heat sink 56 provides additional heat exchange area, enabling more efficient dissipation of heat absorbed by the heat sink 55 into the environment, thereby improving the overall system's heat dissipation capacity.

[0144] For example, the heat sink 56 can be arranged in the form of a pin. This disclosure does not limit the number of heat sinks 56, and the number can be set according to the actual situation.

[0145] For example, there are multiple heat sinks 56, and the multiple heat sinks 56 are arranged in an array on the side of the heat sink 55 away from the main body 51. This facilitates manufacturing.

[0146] The following section describes the connectors of the controller 30.

[0147] In some embodiments, referring to FIG10, the first connector 60 includes a first connecting portion 61, a second connecting portion 62, and a third connecting portion 63. The first connecting portion 61 is connected to a first external terminal 413. The second connecting portion 62 is connected to a first input terminal 52. The plane on which the first connecting portion 61 is located intersects the plane on which the second connecting portion 62 is located. The third connecting portion 63 connects the first connecting portion 61 and the second connecting portion 62.

[0148] In this way, the first connector 60 is modularly designed, allowing the first external terminal 413 and the first input terminal 52 to connect. By using the first connector 60, the connection area is increased, the connection strength is enhanced, and loosening of the connection is prevented.

[0149] Referring to Figure 11, the second connector 70 includes a fourth connecting portion 71, a fifth connecting portion 72, and a sixth connecting portion 73. The fourth connecting portion 71 connects to the second external terminal 423. The fifth connecting portion 72 connects to the second input terminal 53. The plane on which the fourth connecting portion 71 is located intersects with the plane on which the fifth connecting portion 72 is located. The sixth connecting portion 73 connects the fourth connecting portion 71 and the fifth connecting portion 72, and the sixth connecting portion 73 is stacked on top of the third connecting portion 63.

[0150] In this way, the modular design of the second connector 70 allows the second external terminal 423 and the second input terminal 53 to be connected. By setting the second connector 70, the connection area of ​​the controller 30 is increased, the connection strength is enhanced, and loosening of the connection is prevented.

[0151] In some embodiments, the first connecting portion 61 is soldered to the first external terminal 413, and the second connecting portion 62 is soldered to the first input terminal 52. The fourth connecting portion 71 is soldered to the second external terminal 423, and the fifth connecting portion 72 is soldered to the second input terminal 53.

[0152] In this way, the first connector 60 and the second connector 70 are more securely connected by welding.

[0153] For example, the welding method can be laser welding, ultrasonic welding, spot welding, etc. This disclosure does not limit this; the welding method can be set according to the actual needs.

[0154] In some embodiments, referring to FIG17, the controller 30 further includes a third insulating member 74 disposed between the first connector 60 and the second connector 70.

[0155] In this way, by providing the third insulating element 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 minimized, thereby reducing the stray inductance between the first connector 60 and the second connector 70.

[0156] In some other embodiments, the side of the second connector 70 facing the first connector 60 may be provided with an insulating sheet or insulating material. This improves the insulation between the first connector 60 and the second connector 70 and prevents the insulation from failing due to breakage of the third insulating member 74 or other problems.

[0157] To prevent the third insulating member 74 from sliding, adhesive can be applied to the side of the third insulating member 74 facing the first connector to make it adhesive.

[0158] In some other embodiments, referring to Figures 12 and 13, in order to enable the first connector 60 and the second connector 70 to be adapted to the first electronic device 40, the first connector 60 and the second connector 70 may be designed in a Z-shape, which facilitates the installation and connection of the first connector 60 and the second connector 70.

[0159] In this way, the first connector 60 and the second connector 70 can be welded in the same direction, simplifying the processing and improving processing efficiency.

[0160] In some embodiments, referring again to Figures 10 and 11, there are multiple first connecting portions 61, which are spaced apart along the length direction of the first edge 414. There are also multiple fourth connecting portions 71, which are spaced apart along the length direction of the first edge 414.

[0161] In this way, the stress generated by the pressure on the first connecting part 61 and the fourth connecting part 71 during the welding process can be reduced, so that the first connecting part 61 can fully form surface contact with the first external terminal 413 and the fourth connecting part 71 can fully form surface contact with the second external terminal 423, thereby avoiding welding pores and cold solder joints caused by insufficient contact between the first connecting part 61 and the fourth connecting part 71.

[0162] For example, the number of first connecting portions 61 can be two, three, four, etc. This disclosure does not limit this, and the number of first connecting portions 61 can be set according to actual needs.

[0163] In some embodiments, referring to Figures 14 and 15, Figure 15 being a schematic view of the base 80 of Figure 14 from below, the controller 30 further includes a base 80 having a first surface 81 and a second surface 82 facing each other. For example, the first surface 81 is the downward-facing surface of the base 80 in Figure 14, and the second surface 82 is the upward-facing surface of the base 80 in Figure 14.

[0164] The first surface 81 is provided with a mounting groove 811, the first electronic device 40 is mounted in the mounting groove 811, and the second electronic device 50 is provided on the second surface 82 in the area opposite to the mounting groove 811.

[0165] In this way, the first electronic device 40 and the second electronic device 50 are arranged on both sides of the base 80, which effectively saves space and allows more functions to be integrated in a limited space.

[0166] In some embodiments, the second surface 82 includes a convex region that protrudes away from the first surface 81, and the second electronic device 50 is disposed on the top surface of the convex region. The convex region is opposite to the mounting groove 811 in the thickness direction of the base 80.

[0167] This design reduces the size of the base 80, further saving space for the controller 30.

[0168] In some embodiments, the sidewall of the mounting groove 811 is provided with an opening 812, which extends through the side of the convex region, and the second sub-row 412 and the fourth sub-row 422 pass through the opening 812.

[0169] In this way, the second sub-row 412 and the fourth sub-row 422 passing through the opening 812 can facilitate the connection between the first electronic device 40 and the second electronic device 50, and can also reduce the connection loop of the first electronic device 40 and the second electronic device 50, thereby reducing stray inductance.

[0170] In some embodiments, the portion of the base 80 between the bottom surface of the mounting groove 811 and the top surface of the convex region is a sub-base 83, and the base 80 is provided with cooling water channels, at least a portion of which is located within the sub-base portion 83.

[0171] In this way, the cooling water channel is located inside the sub-base 83, which can cool the first electronic device 40 and the second electronic device 50, effectively reduce the operating temperature of the first electronic device 40 and the second electronic device 50, improve thermal management, and extend the service life of the first electronic device 40 and the second electronic device 50.

[0172] In some other embodiments, the base 80 has a hollow bottom surface and is also provided with cooling channels to cool other electronic components.

[0173] In some embodiments, the top surface of the convex region is provided with a clearance opening 813, which communicates with the cooling water channel. The second electronic device 50 includes a heat sink 55 and a heat sink 56 disposed on the side of the heat sink 55 away from the main body 51. The heat sink 55 covers the clearance opening 813, and the heat sink 56 is located in the cooling water channel.

[0174] In this way, the heat sink 56 is located within the cooling water channel, allowing for efficient heat dissipation directly through liquid cooling. This enhances the heat dissipation effect, reduces the temperature of the heat sink 55 and the second electronic component 50, and ensures that they operate within a safe temperature range. Furthermore, embedding the heat sink 56 within the cooling water channel saves overall space in the device, resulting in a more compact design without compromising heat dissipation performance.

[0175] In some embodiments, the mounting groove 811 is provided with an encapsulating material, which fills the space between the first electronic device 40 and the inner wall of the mounting groove 811. For example, the encapsulating material fills the gap between the mounting groove 811 and the first electronic device 40, completely encapsulating the first electronic device 40 within the mounting groove 811.

[0176] In this way, the first electronic device 40 is completely sealed and encapsulated by the packaging material, preventing damage to the first electronic device 40 due to oxidation. In addition, this allows the first electronic device 40 to dissipate heat through the heat conduction of the base 80, improving heat dissipation efficiency.

[0177] The encapsulation material provides additional mechanical support, effectively securing the first electronic device 40, reducing the impact of vibration and shock, and enhancing overall stability. The encapsulation material effectively protects the first electronic device 40 from damage by dust, moisture, and other external contaminants, increasing its lifespan.

[0178] Some embodiments of this disclosure also provide a manufacturing method for manufacturing a controller, as shown in FIG26, the method including steps S101 to S103.

[0179] S101, Assemble the first electronic device.

[0180] S102, Assemble the second electronic device.

[0181] S103. Install the first connector and the second connector.

[0182] For example, a first electronic component is encapsulated in a mounting slot, and encapsulation material is filled to make the first electronic component and the housing a single unit. A second electronic component is installed into the clearance opening, and a locking nut is used to secure the second electronic component tightly to the clearance opening. A first connecting portion and a first output terminal are connected, and a second connecting portion and a first input terminal are connected. Pressure is applied to the first connector, laser focusing is used for positioning, and the first and second connecting portions are welded. A third insulating component is installed. A fourth connecting portion is connected to a second external terminal, and a fifth connecting portion is connected to a second input terminal. Pressure is applied to the second connector, laser focusing is used for positioning, and the fourth and fifth connecting portions are welded.

[0183] In some embodiments, as shown in FIG27, installing the first connector and the second connector includes steps S201 to S103.

[0184] S201. Connect the first connecting part and the first external terminal, connect the second connecting part and the first input terminal, apply pressure to the first connector, and weld the first connecting part and the second connecting part.

[0185] S202, Install the third insulating component.

[0186] S203, connect the fourth connecting part and the second external terminal, connect the fifth connecting part and the second input terminal, apply pressure to the second connector, and weld the third connecting part and the fourth connecting part.

[0187] Referring to Figures 16-18, first connect the first connector 60 to the first electronic device 40 and the second electronic device 50, then install the third insulating component 74, and finally connect the second connector 70 to the first electronic device 40 and the second electronic device 50.

[0188] For example, connecting the first connector 60 to the first electronic device 40 and the second electronic device 50 includes connecting a first connecting portion 61 to a first external terminal 413. A second connecting portion 62 is connected to a first input terminal 52. Pressure is applied to the first connector 60, and the first connecting portion 61 and the second connecting portion 62 are laser-welded. Installing a third insulating member 74 includes covering the first connector 60 with the third insulating member 74. Connecting the second connector 70 to the first electronic device 40 and the second electronic device 50 includes connecting a fourth connecting portion 71 to a second external terminal 423. A fifth connecting portion 72 is connected to a second input terminal 53. Pressure is applied to the second connector 70, and the fourth connecting portion 71 and the fifth connecting portion 72 are welded.

[0189] This makes the connection between the first connector 60 and the second connector 70 more secure.

[0190] In some other embodiments, referring to Figures 19-21, the first connector 60 is first connected to the first electronic device 40 and the second electronic device 50, then the third insulating member 74 is installed, and finally the second connector 70 is connected to the first electronic device 40 and the second electronic device 50.

[0191] Because the first and second connectors are designed in a Z-shape, the first, second, third, and fourth connecting parts face the same side. During welding, the welding machine does not need to change the angle and can complete the welding of the four connecting parts on the same side, saving processing steps and improving processing efficiency.

[0192] In some embodiments, assembling electronic devices includes:

[0193] The first electronic component is assembled into the mounting slot.

[0194] The encapsulation material is filled between the mounting slot and the first electronic component.

[0195] In this way, the encapsulation material fills the space between the mounting groove and the first electronic component, completely encapsulating the first electronic component within the mounting groove. The first electronic component is connected to the housing through the encapsulation material, increasing the contact area and improving heat dissipation efficiency. Furthermore, since a traditional outer casing is not required, heat dissipation is more convenient, further improving heat dissipation efficiency.

[0196] In some embodiments, the thickness of the encapsulation material is 0.5-1.5 mm. Exemplarily, the thickness of the encapsulation material is 0.5 mm, 1 mm, or 1.5 mm.

[0197] In some embodiments, the package includes:

[0198] Fill the encapsulation material so that the liquid level of the encapsulation material is higher than that of the first electronic device.

[0199] The mounting slot is evacuated and vented repeatedly, at least twice.

[0200] This allows air to escape from the packaging material, making the packaging more robust and providing better protection for the primary electronic device.

[0201] Referring to Figures 22 and 23, the metallized film is wound and sputter-coated with gold to obtain the body 43. The solder joint of the first busbar 41 is soldered to the positive electrode of the body 43. The first busbar 41 is then embedded into the positioning groove of the first insulating component 44, with the first insulating component 44 overlapping the first busbar 41. The second busbar 42 is then embedded into the other side of the first insulating component 44, with the first insulating component 44 overlapping the second busbar 42. The solder joint of the second busbar 42 is soldered to the negative electrode of the body 43, completing the assembly of the electronic device.

[0202] To insulate the first electronic device 40 from the bottom of the housing 47, encapsulation material is filled into the bottom of the first accommodating space 471 of the housing 47. A vacuum is then drawn and degassed, repeated at least twice, to minimize air bubbles or pores in the encapsulation material. The encapsulation material is then allowed to solidify over a period of time.

[0203] Referring to Figures 23 and 24, an insulating strip 475 is embedded into the top of the partition 473 to form an insulating end 474, and the first electronic device 40 is installed into the first receiving space 471. A second busbar 42 is embedded into the insulating end 474, ensuring a certain insulating distance between the two sides of the second busbar 42 and the wall of the housing 47. The electronic device is moved towards the partition 473, ensuring a certain insulating distance between the side of the first electronic device 40 facing away from the partition 473 and the wall. This positions the first electronic device 40, ensuring insulation between it and the wall of the housing 47.

[0204] Referring to Figure 23 and Figure 25, fill the first accommodating space 471 with encapsulation material, making the encapsulation material more than 3mm above the upper surface of the electronic device, so that the encapsulation material completely covers the first electronic device 40. Perform vacuuming and degassing again, repeating the cycle more than 2 times. Heat the shell to solidify the encapsulation material.

[0205] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0206] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
