Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, specifically to an on-board controller and a vehicle. Background Technology
[0002] The vehicle controller is fixed to the vehicle frame and is used to receive commands and send signals to control the vehicle's electrical components, such as the braking system and suspension system. To save interior space, the size and weight of the vehicle controller need to be controlled. Utility Model Content
[0003] This application provides an on-board controller and a vehicle. The signal terminals of the on-board controller are integrated into the housing by integral injection molding, which simplifies the structure of the on-board controller and reduces its weight.
[0004] In a first aspect, this application provides an on-board controller, which includes a housing and a cover. The housing includes a base plate and multiple side plates, which together form a receiving groove on the base plate to receive a circuit board. The cover plate seals the opening of the receiving groove. A first side plate among the multiple side plates includes a first outer surface facing away from the receiving groove. One end of multiple signal terminals of the on-board controller extends out of the first outer surface. The first outer surface is used to fix a sleeve, which is spaced around the extended ends of the multiple signal terminals. The length of the sleeve in a direction parallel to the extended ends of the multiple signal terminals is greater than the length of the extended ends of the multiple signal terminals. The housing is made of insulating material and integrally molded. The on-board controller is fixed to the vehicle by screws, and the on-board controller is communicatively connected to the vehicle's on-board electrical components through the multiple signal terminals.
[0005] The vehicle controller provided in this application houses and protects the circuit board through a receiving groove formed by the housing and cover plate. It also uses signal terminals to receive commands and send control signals to control the vehicle's onboard electrical components. The housing is made of insulating material, and the signal terminals are integrally molded within the housing and partially extend beyond the first outer surface of the first side plate. The vehicle controller also uses sleeves fixed to the first outer surface to space around one end of the signal terminals extending beyond the first outer surface, protecting the signal terminals and securing the external signal ports. The signal terminals of the vehicle controller are integrally injection molded into the housing, simplifying the controller's structure and reducing its weight.
[0006] One implementation involves the sleeve being made of the same material as the shell and being integrally formed.
[0007] In one implementation, the sleeve is made of metal, and the shell is fixed to the sleeve by integral molding.
[0008] In one implementation, the sleeve includes two opposing inner cylinder walls, each of the two inner cylinder walls including a plurality of guide bars, each of the plurality of guide bars extending in a direction parallel to the direction in which a plurality of signal terminals extend out of a first outer surface, and the spacing between the guide bars on one of the inner cylinder walls is different from the spacing between the guide bars on the other inner cylinder wall.
[0009] In this implementation, multiple guide bars are used to guide the external signal port into the sleeve and make contact with multiple signal terminals of the vehicle controller. The different spacing between the guide bars on the two inner cylinder walls prevents the external signal port from extending into the sleeve in the opposite direction, ensuring that the multiple signal terminals are aligned with the external signal port.
[0010] In one implementation, the guide bar includes opposing first and second ends along its extension direction, and the projection of the end of each signal terminal extending out of the first outer surface onto the inner cylinder wall is located between the first and second ends.
[0011] In this implementation, the first end of the guide bar near the first side plate is connected to the first side plate, or the distance between the guide bar and the first side plate is less than the length of the signal terminal extending out of the first side plate. The distance between the second end of the guide bar away from the first side plate and the first side plate is greater than the length of the signal terminal extending out of the first side plate. When the external signal port extends into the sleeve, it first contacts the guide bar, continues to extend along the extension direction of the guide bar, and then contacts the signal terminal, ensuring the guiding effect of the guide bar on the external signal port.
[0012] In one implementation, the housing includes a first reinforcing rib, which protrudes from the side plate or bottom plate toward the receiving groove, and at least two first reinforcing ribs on the same surface intersect each other in a cross or star shape.
[0013] In this implementation, the use of a first reinforcing rib can improve the structural rigidity of the shell, reduce the thickness of the bottom plate or side plate, further reduce the weight of the shell and improve its vibration resistance.
[0014] In one implementation, a first reinforcing rib protrudes from the side plate and the bottom plate onto the surface facing the receiving groove.
[0015] One implementation involves multiple first reinforcing ribs intersecting each other in a grid pattern.
[0016] In one implementation, the base plate, circuit board, and cover plate are stacked sequentially, and the cover plate is fixedly connected to the housing by welding.
[0017] In this implementation, the circuit board is arranged parallel to the base plate and cover plate, which reduces the height of the vehicle controller provided in this application. The cover plate is welded and fixed to the housing, which can better seal the receiving groove to protect the circuit board.
[0018] In one implementation, the cover plate is a metal cover plate, and the cover plate is thermally bonded to the shell.
[0019] In one implementation, the cover plate is an insulating cover plate, and the cover plate is laser welded to the shell.
[0020] One implementation involves welding the two opposing surfaces of the cover plate and the housing together along the stacking direction of the base plate and the cover plate.
[0021] In one implementation, the surface of the cover plate facing the circuit board includes a flange along the stacking direction of the base plate and the cover plate, wherein the flange surrounds the outer surface of the housing and fits against the outer surface of the housing along the plane direction of the circuit board; or the flange is received in the slot of the receiving groove and fits against the groove wall of the receiving groove.
[0022] In one implementation, the cover plate includes two flanges, which respectively surround the outer surface of the housing and the opening of the receiving groove.
[0023] One implementation involves a gap between one flange and the housing used to secure a sealing ring.
[0024] In one implementation, along the direction of the stacking of the base plate and the cover plate, the surface of the cover plate facing away from the circuit board includes a second reinforcing rib, and at least two second reinforcing ribs intersect each other in a cross shape or a star shape.
[0025] In this implementation, the use of a second reinforcing rib can improve the structural rigidity of the cover plate, reduce the thickness of the cover plate, reduce the weight of the cover plate, and improve the vibration resistance of the cover plate.
[0026] One implementation involves multiple second reinforcing ribs intersecting each other in a grid pattern.
[0027] In one implementation, the housing includes a first boss located within a receiving groove and connected to a first side plate. The first boss includes a first top surface facing the circuit board. Along the direction of the stacking of the bottom plate and the cover plate, the bottom plate, the first top surface, and the circuit board are arranged in sequence. The other ends of a plurality of signal terminals extend out of the first top surface and are soldered to the circuit board and connected.
[0028] In this implementation, the housing secures the middle sections of multiple signal terminals via a first protrusion connected to the first side plate. The other ends of the multiple signal terminals extend from the first protrusion toward the first top surface of the circuit board and are soldered to the circuit board for electrical connection, thereby enabling signal transmission and reception between the circuit board and external signal ports through the multiple signal terminals. The soldering of the multiple signal terminals to the circuit board also serves to secure the circuit board.
[0029] In one implementation, each signal terminal includes a first segment and a second segment connected together. The first segment extends in a direction perpendicular to the first side plate and partially protrudes from the first side plate. The second segment extends in a direction where the base plate and the cover plate are stacked and protrudes from the first top surface and is soldered to the circuit board for conduction.
[0030] One implementation involves arranging multiple first segments relative to a first side plate array.
[0031] In one implementation, the outer surface of the housing includes a plurality of draft grooves, each draft groove extending toward the center of the receiving groove.
[0032] In this implementation, the draft groove is used to reduce the wall thickness of the shell, making it easier to remove the mold after the shell is integrally formed.
[0033] In one implementation, the draft groove is located on the first side plate, and the draft groove is received within the orthographic projection of the first boss along a direction parallel to the extension of the first outer surface of the plurality of signal terminals.
[0034] One implementation involves a row of draft grooves between any two adjacent rows of the first segment along the stacking direction of the base plate and the cover plate.
[0035] In one implementation, the first outer surface of the first side plate includes a plurality of protrusions, which are received within the orthographic projection of the sleeve. The plurality of protrusions are arranged alternately with a plurality of draft grooves in at least one row of draft grooves, and each protrusion is used to space adjacent rows of first segments to prevent short circuits.
[0036] In one implementation, the first boss is connected to the base plate, and the draft groove is located on the base plate. The draft groove is received within the orthographic projection of the first boss along the stacking direction of the base plate and the cover plate.
[0037] In the two implementation methods mentioned above, since the first boss has a certain thickness to fix multiple signal terminals, by setting a draft groove on the outer surface of the first side plate or the outer surface of the bottom plate and extending it toward the first boss, the thickness of the first boss can be reduced, which makes it easier to integrally form the first boss and make it easier to remove the first boss from the mold.
[0038] In one implementation, the depth of the draft groove is greater than the thickness of the base plate, and part of the draft groove extends into the first boss.
[0039] In one implementation, the housing includes a plurality of second bosses located within a receiving groove and respectively connected to a side plate. Any one of the plurality of second bosses is connected to at least one of the plurality of side plates. Along the stacking direction of the bottom plate and the cover plate, each second boss includes a second top surface facing the circuit board, the second top surface being used to support the circuit board.
[0040] In this implementation, the housing supports the circuit board via a second protrusion connected to a portion of the side plate, such that the circuit board and the first protrusion are spaced apart, and the other ends of multiple signal terminals extend out of the first top surface of the first protrusion and are soldered to the circuit board for conduction.
[0041] In one implementation, two second protrusions are arranged on either side of the first protrusion along a direction perpendicular to the direction in which multiple signal terminals extend from the first outer surface.
[0042] In this implementation, the two second protrusions are positioned on either side of the first protrusion, which can reliably support the circuit board near multiple signal terminals and prevent the circuit board from undergoing large deformation due to soldering.
[0043] In one implementation, a plurality of side plates include a second side plate, which is spaced apart from the first side plate along a direction parallel to the first outer surface of a plurality of signal terminals, and the second side plate is used to fix at least two of the plurality of second bosses.
[0044] In this implementation, multiple second protrusions are arranged at intervals along a direction parallel to the multiple signal terminals extending out of the first outer surface, which can provide better support for the circuit board and make the circuit board more uniformly stressed.
[0045] In one implementation, the surface of the second boss facing the circuit board is used to fix a snap-fit component, which passes through the circuit board and snaps into and fixes itself to the circuit board.
[0046] In one implementation, the surface of the second boss facing the circuit board is used to fix a guide post, which passes through the circuit board and prevents the circuit board from shifting relative to multiple signal terminals.
[0047] In one implementation, the surface of the second boss facing the circuit board includes a bolt hole for inserting a portion of a bolt, the bolt head being located on the side of the circuit board away from the second boss and being press-fitted to the circuit board.
[0048] In one implementation, a plurality of side plates include one second side plate and two third side plates. The second side plate is arranged opposite to the first side plate, and the two third side plates are located on either side of the second side plate. Each third side plate is used to connect the first side plate and the second side plate. The number of second bosses connected to the second side plate is greater than the number of second bosses connected to the first side plate, and is greater than or equal to the number of second bosses connected to the third side plate.
[0049] In this implementation, the other end of the signal terminal extending from the first boss on one side of the first side plate is soldered to the circuit board, which provides a good fixation effect for the circuit board. The second side plate has a large number of second bosses, which can be used to fix the circuit board through interfaces such as snap-fit connectors or bolt holes, resulting in a more balanced force distribution on the circuit board along the direction in which the signal terminal extends from the first outer surface.
[0050] In one implementation, the surface of the second boss connected to the second side plate facing the circuit board includes bolt holes, and the surface of the second boss connected to the third side plate or the first side plate facing the circuit board includes snap-fit components or guide posts.
[0051] In this implementation, the bolt holding force of the bolt hole is relatively large, which can balance the force on the circuit board along the direction of the signal terminal extending from the first outer surface.
[0052] In one implementation, the second boss connected to the third side plate is used to fix the bolt, and the second boss connected to the second side plate or the first side plate is used to fix the snap-fit component.
[0053] In one implementation, a base plate is used to embed four metal sleeves. Each of the four metal sleeves is arranged around the periphery of multiple side plates. The four metal sleeves are arranged in two pairs of diagonal pairs on the base plate. The maximum area enclosed by the outer edges of the four metal sleeves is smaller than the area of the base plate. The inner holes of each metal sleeve penetrate the base plate along the stacking direction of the base plate and the cover plate. The vehicle controller is fixed to the vehicle with screws through the metal sleeves.
[0054] In this implementation, the metal sleeve has high rigidity. By integrally molding the metal sleeve and embedding it into the base plate for passing through the screw, the connection between the vehicle controller provided in this application and the vehicle frame can be made more secure, avoiding cracking of the base plate due to long-term fatigue stress.
[0055] In one implementation, the base plate includes multiple support protrusions extending away from the cover plate along the stacking direction of the base plate and the cover plate. Each support protrusion is correspondingly located at a metal sleeve to reduce the area of the base plate's contact surface with the vehicle and facilitate flatness processing.
[0056] In one implementation, the junction of the two side plates includes an arc-shaped corner, the center of which is located outside the receiving groove, and the metal sleeve portion extends into the arc-shaped corner.
[0057] In this implementation, the arc-shaped corner is recessed towards the center of the receiving groove to avoid the metal sleeve and the screw passing through the metal sleeve, thereby reducing the area of the base plate and reducing the overall size of the vehicle controller provided in this application.
[0058] In one implementation, the cover plate is a metal cover plate, the cover plate includes a shielding component, the circuit board includes a metal component, and the shielding component abuts against the metal component along the direction of the stacking of the base plate and the cover plate.
[0059] In one implementation, the cover plate is an insulating cover plate, the cover plate includes shielding protrusions, the surface of the shielding protrusions includes a metal layer, the circuit board includes a metal component, and the shielding protrusions abut against the metal component along the stacking direction of the base plate and the cover plate.
[0060] In the two implementation methods described above, the shielding component or shielding protrusion abuts against the metal component, which can form electromagnetic shielding for the devices located on both sides of the metal component on the circuit board, or form electromagnetic shielding for the devices and signal terminals located on both sides of the metal component, to prevent mutual interference between the devices on both sides.
[0061] In one implementation, the cover plate includes a heat dissipation groove, which is recessed toward the circuit board along the stacking direction of the base plate and the cover plate. The bottom surface of the heat dissipation groove toward the circuit board is used to fix a thermal pad, which is used to adhere to the components on the circuit board.
[0062] In this implementation, by setting heat dissipation grooves and thermal pads in the areas corresponding to certain components on the cover plate, heat from some components can be dissipated, which helps with the overall heat dissipation of the circuit board. Some of these components can be those that generate a lot of heat on the circuit board, such as power supply capacitors.
[0063] Secondly, this application provides a vehicle that includes an on-board controller provided in any of the above implementations. The on-board controller is fixed to the vehicle's frame and is used to send signals to the vehicle's braking system or suspension system. Because the vehicle provided in this application uses the aforementioned on-board controller, the vehicle has a more compact structure, resulting in greater interior space, while simultaneously reducing overall weight.

Each signal terminal 103 extends from one end of a first outer surface 1211 for communicative connection with the external signal port, enabling the circuit board 102 to communicate with the vehicle's on-board electrical components 202 via the signal terminals 103. The circuit board 102 is capable of receiving commands from the outside and sending signals to the on-board electrical components 202. That is, the on-board controller 100 is communicatively connected to the vehicle's on-board electrical components 202 via multiple signal terminals 103.
[0117] The vehicle controller 100 provided in this application accommodates and protects the circuit board 102 through the receiving groove 101 formed by the housing 10 and the cover plate 20. It also realizes the function of receiving instructions and sending control signals through the signal terminal 103, so that the vehicle controller 100 can receive external instructions and control the vehicle electrical components 202 of the vehicle 200.
[0118] The housing 10 is made of insulating material. The signal terminal 103 is integrally formed within the housing 10 and partially extends beyond the first outer surface 1211 of the first side plate 121. The vehicle controller 100 provided in this application also protects the signal terminal 103 and secures the external signal port by means of a sleeve 30 fixed to the first outer surface 1211 at intervals around one end of the signal terminal 103. The signal terminal 103 of the vehicle controller 100 provided in this application is integrally injection molded into the housing 10, which strengthens the structural strength of the vehicle controller 100 and helps to reduce its size and weight.
[0119] Because the vehicle 200 provided in this application uses the aforementioned vehicle controller 100, the structure of the vehicle 200 is more compact, thus having a larger interior space, while reducing the overall weight.
[0120] In one embodiment, the sleeve 30 includes two opposing inner cylinder walls 31. Each inner cylinder wall 31 includes a plurality of guide strips 32. The extension direction of each of the plurality of guide strips 32 is parallel to the direction in which the plurality of signal terminals 103 extend from the first outer surface 1211. The spacing between the guide strips 32 on one of the two inner cylinder walls 31 is different from the spacing between the guide strips 32 on the other inner cylinder wall 31. The plurality of guide strips 32 are used to guide external signal ports into the sleeve 30 and to make contact with and conduct electricity to the plurality of signal terminals 103 of the vehicle controller 100.
[0121] Please see Figure 7 This is a schematic diagram of a partial structure of an on-board controller 100 provided in one embodiment of this application.
[0122] For ease of description, in the following embodiments, the two inner cylinder walls 31 are defined as the first inner cylinder wall 311 and the second inner cylinder wall 312, respectively. Each guide bar 32 located on the first inner cylinder wall 311 is defined as the first guide bar 321. Each guide bar 32 located on the second inner cylinder wall 312 is defined as the second guide bar 322.
[0123] In one embodiment, the first inner cylinder wall 311 includes three first guide bars 321. The second inner cylinder wall 312 includes three second guide bars 322. The external signal port includes two opposing outer surfaces. The two outer surfaces are respectively used to at least partially conform to the first inner cylinder wall 311 and the second inner cylinder wall 312. Each outer surface includes three grooves. Each groove is used to receive one first guide bar 321 or one second guide bar 322, such that the external signal port extends into the sleeve 30 along the extending direction of the guide bar 32.
[0124] The multiple signal terminals 103 include multiple first signal terminals 1031 and multiple second signal terminals 1032. The multiple first signal terminals 1031 and multiple second signal terminals 1032 are arranged at intervals. The dimensions of the first signal terminals 1031 and the second signal terminals 1032 are different. The external signal port includes corresponding multiple first interfaces and multiple second interfaces. After the external signal port extends into the sleeve 30, the multiple first interfaces correspond one-to-one with the multiple first signal terminals 1031 and are communicatively connected, and the multiple second interfaces correspond one-to-one with the multiple second signal terminals 1032 and are communicatively connected, thereby communicatively connecting the external signal port and the circuit board 102.
[0125] The spacing between two adjacent first guide bars 321 is L1 and L2, respectively. The spacing between two adjacent second guide bars 322 is L3 and L4, respectively. The second spacing L2 is greater than the fourth spacing L4. This means the spacing between the grooves of the external signal port is different. When the external signal port is reversed, the positions of the grooves and guide bars 32 are staggered to prevent the external signal port from extending backward into the sleeve 30, ensuring that multiple signal terminals 103 are aligned with the external signal port. This also ensures that each first interface is aligned with a first signal terminal 1031, and each second interface is aligned with a second signal terminal 1032.
[0126] In some embodiments, the number of first guide bars 321 on the first inner cylinder wall 311 and the number of second guide bars 322 on the second inner cylinder wall 312 can be arbitrarily set. The two outer surfaces of the external signal port each include a corresponding number of grooves, which also allows the external signal port to extend into the sleeve 30 along the extending direction of the guide bars 32.
[0127] In one embodiment, the number of first guide bars 321 is not equal to the number of second guide bars 322. The number of grooves on the two outer surfaces of the external signal port is equal to the number of first guide bars 321 and second guide bars 322, respectively, allowing the external signal port to extend into the sleeve 30 along the extension direction of the guide bars 32. When the external signal interface is reversed, the unequal number of grooves on the two outer surfaces prevents the external signal port from extending into the sleeve 30 in the reverse direction, ensuring that the multiple signal terminals 103 are aligned with the external signal port.
[0128] Please see Figure 8 This is a schematic cross-sectional view of another part of the vehicle controller 100 provided in one embodiment of this application.
[0129] In one embodiment, the guide bar 32 includes opposing first ends 323 and second ends 324 along its extension direction. The projection of the end of each signal terminal 103 extending from the first outer surface 1211 onto the inner cylinder wall 31 lies between the first end 323 and the second end 324.
[0130] In one embodiment, the first end 323 of the guide strip 32 is connected to the first side plate 121. Along the extending direction of the guide strip 32, the length of the guide strip 32 is greater than the length of the portion of each signal terminal 103 extending out of the first side plate 121. Along the extending direction of the guide strip 32, the distance between the second end 324 and the first side plate 121 is greater than the length of the portion of each signal terminal 103 extending out of the first side plate 121.
[0131] That is, the second end 324 is located on the side of each signal terminal 103 away from the first side plate 121. When the external signal port extends into the sleeve 30, it first contacts the second end 324 of the guide bar 32. The external signal terminal can continue to extend into the sleeve 30 along the extension direction of the guide bar 32, and then contact the signal terminal 103, ensuring the guiding effect of the guide bar 32 on the external signal port, and avoiding damage or bending of the signal terminal 103 due to the external signal terminal contacting the signal terminal 103 first.
[0132] In one embodiment, the first end 323 of the guide strip 32 is spaced apart from the first side plate 121. Along the extending direction of the guide strip 32, the distance between the first end 323 and the first side plate 121 is less than the length of the portion of each signal terminal 103 extending out of the first side plate 121. Along the extending direction of the guide strip 32, the distance between the second end 324 and the first side plate 121 is greater than the length of the portion of each signal terminal 103 extending out of the first side plate 121.
[0133] Similarly, the second end 324 is located on the side of each signal terminal 103 away from the first side plate 121. That is, when the external signal port extends into the sleeve 30, it first contacts the second end 324 of the guide bar 32, and then continues to extend along the extension direction of the guide bar 32 and contacts the signal terminal 103. This ensures the guiding effect of the guide bar 32 on the external signal port and avoids the external signal terminal from contacting the signal terminal 103 first, which could cause damage or bending to the signal terminal 103.
[0134] In one embodiment, the sleeve 30 is made of the same material as the housing 10 and is integrally formed, which reduces the manufacturing steps of the vehicle controller 100 and makes the connection between the sleeve 30 and the housing 10 more reliable.
[0135] In one embodiment, the sleeve 30 is made of metal. The housing 10 is integrally formed to fix the sleeve 30, ensuring higher reliability of the connection between the sleeve 30 and the housing 10. The sleeve 30, made of metal, has higher structural rigidity, thereby improving the protection effect of the sleeve 30 on the signal terminal 103.
[0136] In one embodiment, the base plate 11, circuit board 102, and cover plate 20 are stacked sequentially. The cover plate 20 is fixedly connected to the housing 10 by welding. The circuit board 102 is arranged parallel to the base plate 11 and cover plate 20, which can reduce the height of the vehicle controller 100 provided in this application. The cover plate 20 is fixedly welded to the housing 10, which can better seal the receiving groove 101 to protect the circuit board 102.
[0137] In one embodiment, along the stacking direction of the base plate 11 and the cover plate 20, the two opposing surfaces of the cover plate 20 and the housing 10 are welded together to better seal the receiving groove 101 and improve the protection effect on the circuit board 102.
[0138] Please see Figures 9-11 ,in Figure 9 This illustration shows another partial cross-sectional view of the vehicle controller 100 provided in one embodiment of this application; Figure 10 This illustration shows another partial cross-sectional view of the vehicle controller 100 provided in one embodiment of this application; Figure 11 This illustration shows another partial cross-sectional view of the vehicle controller 100 provided in one embodiment of this application.
[0139] In one embodiment, along the stacking direction of the base plate 11 and the cover plate 20, the surface of the cover plate 20 facing the circuit board 102 includes a flange 21. Along the planar direction of the circuit board 102, the flange 21 surrounds and abuts the outer surface of the housing 10. That is, the flange 21 abuts the surface of each side plate 12 on the side opposite to the receiving groove 101, thereby increasing the contact area between the cover plate 20 and the housing 10, improving the sealing effect of the cover plate 20 on the receiving groove 101, and protecting the circuit board 102.
[0140] In one embodiment, along the planar direction of the circuit board 102, the flange 21 of the cover plate 20 is received in the opening of the receiving groove 101 and abuts against the groove wall of the receiving groove 101. That is, the flange 21 abuts against the surface of each side plate 12 facing the receiving groove 101, so that the cover plate 20 and the housing 10 also have a larger contact area, improving the sealing effect of the cover plate 20 on the receiving groove 101 to protect the circuit board 102.
[0141] In one embodiment, along the stacking direction of the base plate 11 and the cover plate 20, the surface of the cover plate 20 facing the circuit board 102 includes two flanges 21. The two flanges 21 respectively surround the outer surface of the housing 10 and the slot received in the receiving groove 101.
[0142] For ease of description, in subsequent embodiments, along the planar direction of the circuit board 102, the flange 21 farther from the geometric center of the cover plate 20 is defined as the first flange 22, and the flange 21 closer to the geometric center of the cover plate 20 is defined as the second flange 23. That is, the first flange 22 surrounds the outer surface of the housing 10, and the second flange 23 is received in the slot of the receiving groove 101.
[0143] In one embodiment, the first flange 22 is used to fit against the outer surface of the housing 10, so that the cover plate 20 and the housing 10 have a larger contact area, thereby improving the sealing effect of the cover plate 20 on the receiving groove 101 to protect the circuit board 102.
[0144] In one embodiment, the second flange 23 is used to fit against the wall of the receiving groove 101, which also makes the cover plate 20 and the housing 10 have a larger contact area, improving the sealing effect of the cover plate 20 on the receiving groove 101 to protect the circuit board 102.
[0145] In one embodiment, the vehicle controller 100 includes a sealing ring 40. The sealing ring 40 is fixed in the gap between a flange 21 and the housing 10.
[0146] In one embodiment, the second flange 23 is used to fit against the wall of the receiving groove 101. A gap is left between the first flange 22 and the outer surface of the housing 10. The sealing ring 40 is fixed in the gap between the first flange 22 and the outer surface of the housing 10, further improving the sealing effect of the cover plate 20 on the receiving groove 101 to protect the circuit board 102.
[0147] In one embodiment, the first flange 22 is used to fit against the outer surface of the housing 10. A gap is left between the second flange 23 and the groove wall of the receiving groove 101. The sealing ring 40 is fixed in the gap between the second flange 23 and the groove wall of the receiving groove 101, further improving the sealing effect of the cover plate 20 on the receiving groove 101 to protect the circuit board 102.
[0148] In one embodiment, the cover plate 20 is a metal cover plate. The cover plate 20 is thermally bonded to the housing 10, which makes the connection between the cover plate 20 and the housing 10 highly reliable. The cover plate made of metal material can improve the overall structural rigidity of the vehicle controller 100 and ensure the protection of the circuit board 102.
[0149] In one embodiment, the cover plate 20 is an insulating cover plate. The cover plate 20 is laser welded to the housing 10, which also makes the connection between the cover plate 20 and the housing 10 highly reliable.
[0150] In one embodiment, the housing 10 includes a first reinforcing rib 104. The first reinforcing rib 104 protrudes from the surface of the side plate 12 or the bottom plate 11 facing the receiving groove 101. At least two first reinforcing ribs 104 located on the same surface intersect each other in a cross or star shape.
[0151] Please see Figure 12 and Figure 13 ,in, Figure 12 This illustration shows another partial structural diagram of the vehicle controller 100 provided in one embodiment of this application; Figure 13 This illustration shows a structural diagram of a cover plate 20 provided in one embodiment of this application.
[0152] In one embodiment, the first reinforcing rib 104 protrudes from the surface of the base plate 11 facing the receiving groove 101. The use of the first reinforcing rib 104 in the housing 10 can improve the structural rigidity of the housing 10, reduce the thickness of the base plate 11, further reduce the weight of the housing 10, and improve the vibration resistance of the housing 10.
[0153] In one embodiment, the first reinforcing rib 104 protrudes from the side plate 12 and the bottom plate 11 on the surface facing the receiving groove 101, further improving the structural rigidity of the housing 10, reducing the thickness of the bottom plate 11 and the side plate 12, reducing the weight of the housing 10 and improving the vibration resistance of the housing 10.
[0154] In one embodiment, multiple first reinforcing ribs 104 intersect each other in a grid pattern, which can further improve the structural rigidity of the shell 10 and the vibration resistance of the shell 10.
[0155] In one embodiment, along the stacking direction of the base plate 11 and the cover plate 20, the surface of the cover plate 20 facing away from the circuit board 102 includes second reinforcing ribs 24. At least two second reinforcing ribs 24 intersect each other in a cross or star shape. The cover plate 20 with second reinforcing ribs 24 can improve the structural rigidity of the cover plate 20, reduce the thickness of the cover plate 20, reduce the weight of the cover plate 20, and improve the vibration resistance of the cover plate 20.
[0156] In one embodiment, multiple second reinforcing ribs 24 intersect each other in a grid pattern, which can further improve the structural rigidity of the cover plate 20 and its vibration damping capability.
[0157] Please see Figure 14 This is a schematic cross-sectional view of another part of the vehicle controller 100 provided in one embodiment of this application.
[0158] In one embodiment, the housing 10 includes a first boss 13. The first boss 13 is located within a receiving groove 101 and connected to a first side plate 121. The first boss 13 includes a first top surface 131 facing the circuit board 102. Along the stacking direction of the base plate 11 and the cover plate 20, the base plate 11, the first top surface 131, and the circuit board 102 are arranged sequentially, and the other ends of a plurality of signal terminals 103 extend out of the first top surface 131 and are soldered to and connected to the circuit board 102.
[0159] That is, the housing 10 fixes the middle section of multiple signal terminals 103 through the first boss 13 connected to the first side plate 121. The other end of the multiple signal terminals 103 extends from the first boss 13 toward the first top surface 131 of the circuit board 102 and is soldered to the circuit board 102 for conduction, thereby realizing the signal transmission and reception function between the circuit board 102 and the external signal port through the multiple signal terminals 103. The soldering and conduction of the multiple signal terminals 103 to the circuit board 102 also serves to fix the circuit board 102.
[0160] In one embodiment, each signal terminal 103 includes a connected first segment 1033 and a second segment 1034. The first segment 1033 extends in a direction perpendicular to the first side plate 121 and partially extends beyond the first side plate 121. The second segment 1034 extends in a direction in which the base plate 11 and the cover plate 20 are stacked and extends beyond the first top surface 131 and is soldered to the circuit board 102 for electrical connection.
[0161] In one embodiment, the first boss 13 includes a plurality of first top surfaces 131. Along the stacking direction of the base plate 11 and the cover plate 20, the plurality of first top surfaces 131 are arranged sequentially at intervals. That is, each first top surface 131 has a different height. The distance between the first segment 1033 of the signal terminal 103 and the circuit board 102 is relatively small, and the second segment 1034 of the signal terminal 103 extends from the higher first top surface 131, resulting in a larger contact area between the signal terminal 103 and the first boss 13, ensuring the effective fixation of the signal terminal 103 by the first boss 13.
[0162] Please see Figure 15 and Figure 16 ,in, Figure 15 This illustration shows a partially enlarged structural diagram of an on-board controller 100 provided in one embodiment of this application; Figure 16 This illustration shows another partially enlarged structural diagram of the vehicle controller 100 provided in one embodiment of this application.
[0163] In one embodiment, multiple first segments 1033 are arranged in an array relative to the first side panel 121 to ensure that enough first segments 1033 can be connected to external signal ports and to reduce the space occupied by the multiple first segments 1033 on the first side panel 121, thereby improving the integration of the vehicle controller 100.
[0164] In one embodiment, a plurality of second segments 1034 are arranged in an array relative to the circuit board 102 to ensure that enough second segments 1034 are connected to the circuit board 102 and to reduce the space occupied by the plurality of second segments 1034 on the circuit board 102, thereby improving the integration of the vehicle controller 100.
[0165] In one embodiment, the outer surface of the housing 10 includes a plurality of draft grooves 105. Each draft groove 105 extends toward the center of the receiving groove 101. The draft grooves 105 are used to reduce the wall thickness of the housing 10, facilitating the removal of the mold after the housing 10 is integrally formed.
[0166] Please see Figure 17 This is a schematic cross-sectional view of another part of the vehicle controller 100 provided in one embodiment of this application.
[0167] In one embodiment, a draft groove 105 is located on the first outer surface 1211 of the first side plate 121. The draft groove 105 is received within the orthographic projection of the first boss 13 along a direction parallel to the extension of the plurality of signal terminals 103 from the first outer surface 1211. The first boss 13 has a certain thickness to secure the plurality of signal terminals 103. By providing a draft groove 105 extending toward the first boss 13 on the first outer surface 1211 of the first side plate 121, the thickness of the first boss 13 can be reduced, facilitating integral molding of the first boss 13 and making it easier to remove the first boss 13 from the mold, thus improving the manufacturing efficiency of the vehicle controller 100. The draft groove 105 also allows the first side plate 121 to have a smaller wall thickness at the first boss 13, thereby reducing the weight of the housing 10.
[0168] In one embodiment, along the stacking direction of the base plate 11 and the cover plate 20, a row of draft grooves 105 is included between any two adjacent rows of the first segments 1033, which can also reduce the thickness of the first boss 13 and reduce the weight of the housing 10.
[0169] In one embodiment, the first outer surface 1211 of the first side plate 121 includes a plurality of protrusions 1212. The plurality of protrusions 1212 are received within the orthographic projection of the sleeve 30. The plurality of protrusions 1212 are arranged alternately with a plurality of draft grooves 105 in at least one row of draft grooves 105. Each protrusion 1212 is used to space adjacent rows of first segments 1033 to prevent short circuits.
[0170] In one embodiment, draft grooves 105 are located on the first top surface 131 of the first boss 13. Each draft groove 105 extends toward the base plate 11. A row of draft grooves 105 is included between any two adjacent rows of second segments 1034, which can also reduce the thickness of the first boss 13 and reduce the weight of the housing 10.
[0171] Please see Figure 18 and Figure 19 ,in, Figure 18 This illustration shows a structural diagram of the housing 10 provided in one embodiment of this application; Figure 19 This illustration shows a partial cross-sectional structural diagram of the housing 10 provided in one embodiment of this application.
[0172] In one embodiment, the first boss 13 extends toward and connects to the base plate 11. A draft groove 105 is located on the base plate 11. Along the stacking direction of the base plate 11 and the cover plate 20, the draft groove 105 is received within the orthographic projection of the first boss 13. By providing a draft groove 105 extending toward the first boss 13 on the outer surface of the base plate 11 away from the receiving groove 101, the thickness of the first boss 13 can also be reduced, facilitating the integral molding of the first boss 13 and facilitating the removal of the first boss 13 from the mold, thereby improving the manufacturing efficiency of the vehicle controller 100. The draft groove 105 also allows the base plate 11 to have a smaller wall thickness at the first boss 13, thereby reducing the weight of the housing 10.
[0173] In one embodiment, the depth of the draft groove 105 is greater than the thickness of the base plate 11. The draft groove 105 extends partially into the first boss 13. The deeper draft groove 105 facilitates the removal of the mold from the first boss 13 and further reduces the wall thickness of the base plate 11 at the first boss 13, thereby reducing the weight of the housing 10.
[0174] Please see Figure 20 and Figure 21 ,in, Figure 20 This illustration shows a partial structural diagram of the housing 10 provided in one embodiment of this application; Figure 21 This illustrates another partial structural diagram of the housing 10 provided in one embodiment of this application.
[0175] In one embodiment, the housing 10 includes a plurality of second bosses 14. The plurality of second bosses 14 are located within a receiving groove 101 and are respectively connected to side plates 12. Any one of the plurality of second bosses 14 is connected to at least one of the plurality of side plates 12. Each second boss 14 includes a second top surface 141 facing the circuit board 102 along the stacking direction of the base plate 11 and the cover plate 20. The second top surface 141 supports the circuit board 102. The housing 10 supports the circuit board 102 via the second bosses connected to portions of the side plates 12, such that the circuit board 102 is spaced apart from the first bosses 13 along the stacking direction of the base plate 11 and the cover plate 20. The other ends of a plurality of signal terminals 103 extend beyond the first top surface 131 of the first bosses 13 and are soldered to the circuit board 102 for electrical connection.
[0176] In one embodiment, two second protrusions 14 are positioned on either side of the first protrusion 13 along a direction perpendicular to the direction in which the plurality of signal terminals 103 extend from the first outer surface 1211. This allows the two second protrusions 14 to provide reliable support for the circuit board 102 near the plurality of signal terminals 103, thereby limiting the position of the circuit board 102 within the receiving groove 101. Furthermore, supporting the circuit board 102 with the two second protrusions 14 also prevents significant deformation of the circuit board 102 after it is soldered to the signal terminals 103.
[0177] In one embodiment, the plurality of side plates 12 includes a second side plate 122. The second side plate 122 is spaced apart from the first side plate 121 along a direction parallel to the plurality of signal terminals 103 extending from the first outer surface 1211. The second side plate 122 is used to fix at least two of the plurality of second protrusions 14. The spaced arrangement of the plurality of second protrusions 14 along a direction parallel to the plurality of signal terminals 103 extending from the first outer surface 1211 provides better support for the circuit board 102, resulting in more uniform stress on the circuit board 102.
[0178] In one embodiment, the plurality of side plates 12 include two third side plates 123. Each third side plate 123 is used to connect the first side plate 121 and the second side plate 122. The second boss 14 can be fixed to the third side plate 123. The second boss 14 can be set in more positions to support the circuit board 102, which can provide better support for the circuit board 102 and make the circuit board 102 more evenly stressed.
[0179] Please see Figures 22-24 ,in, Figure 22 This illustration shows another partial cross-sectional view of the housing 10 provided in one embodiment of this application; Figure 23 This illustration shows another partial cross-sectional view of the housing 10 provided in one embodiment of this application; Figure 24 This illustrates another partial cross-sectional structure of the housing 10 provided in one embodiment of the present application.
[0180] In one embodiment, the surface of the second protrusion 14 facing the circuit board 102 is used to fix a snap-fit member 15. The snap-fit member 15 is used to pass through the circuit board 102 and snap-fit to the circuit board 102. Along the stacking direction of the base plate 11 and the cover plate 20, the snap-fit member 15 and the second top surface 141 are respectively used to abut against the two sides of the circuit board 102 to prevent the circuit board 102 from shifting relative to the plurality of signal terminals 103, thereby ensuring a reliable connection between the circuit board 102 and the plurality of signal terminals 103.
[0181] In one embodiment, the second boss 14 includes a fixing surface 142. Along the stacking direction of the base plate 11 and the cover plate 20, the fixing surface 142 is located on the side of the second top surface 141 facing away from the circuit board 102. The fixing surface 142 is used to fix the snap-fit member 15. The snap-fit member 15 is used to limit the displacement of the circuit board 102 along its planar direction and the displacement of the circuit board toward the cover plate 20. The second top surface 141 is used to support the circuit board 102.

[0197] In the various embodiments described above, the circuit board 102 includes a plurality of devices 1022. The shielding member 25 or shielding protrusion 26 of the cover plate 20 abuts against the metal member 1021 of the circuit board 102, thereby forming electromagnetic shielding for the devices 1022 located on both sides of the metal member 1021 on the circuit board 102 and preventing mutual interference between the plurality of devices 1022.
[0198] In one embodiment, the shielding member 25 or shielding protrusion 26 of the cover plate 20 and the metal member 1021 of the circuit board 102 can also form electromagnetic shielding for the device 1022 and signal terminal 103 on the circuit board 102, preventing mutual interference between the device 1022 and the signal terminal 103.
[0199] Please see Figure 29This is a schematic cross-sectional view of another part of the vehicle controller 100 provided in one embodiment of this application.
[0200] In one embodiment, the cover plate 20 includes a heat dissipation groove 27 and a thermal pad 28. Along the stacking direction of the base plate 11 and the cover plate 20, the heat dissipation groove 27 is recessed towards the circuit board 102. The bottom surface of the heat dissipation groove 27 facing the circuit board 102 is used to fix a thermal pad 28. The thermal pad 28 is used to abut against a device 1022 on the circuit board 102. That is, the projection of the device 1022 on the cover plate 20 is located within the heat dissipation groove 27. By providing the heat dissipation groove 27 and the thermal pad 28 in the area of the cover plate 20 corresponding to the device 1022, the heat of the device 1022 can be dissipated, which is beneficial to the overall heat dissipation of the circuit board 102. The device 1022 can be a device 1022 that generates a large amount of heat in the circuit board 102, such as a power supply capacitor.
[0201] In one embodiment, there are multiple devices 1022 that generate significant heat. The cover plate 20 includes multiple heat dissipation grooves 27 and multiple thermal pads 28. Each thermal pad 28 is used to adhere to one device 1022. The bottom surface of each heat dissipation groove 27 is used to fix one thermal pad 28. The multiple heat dissipation grooves 27 are used to conduct heat away from the multiple devices 1022, further improving the overall heat dissipation effect of the circuit board 102.
[0202] In one embodiment, the cover plate 20 includes a heat dissipation groove 27 and a plurality of thermal pads 28. Each thermal pad 28 is fixed to the bottom surface of the heat dissipation groove 27 for contacting a device 1022. Along the stacking direction of the base plate 11 and the cover plate 20, the dimensions of each device 1022 are different, resulting in different gap dimensions between each device 1022 and the bottom surface of the heat dissipation groove 27. Each thermal pad 28 has a different size along the stacking direction of the base plate 11 and the cover plate 20, used to fill the gaps between each device 1022 and the bottom surface of the heat dissipation groove 27, allowing heat from multiple devices 1022 to be dissipated through a single heat dissipation groove 27, thus improving the overall heat dissipation effect of the circuit board 102.
