Description

A vehicle area controller structure Technical Field

[0001] This utility model relates to the field of automotive controller technology, specifically to a vehicle area controller structure. Background Technology

[0002] With the rapid development of technology, intelligent connected vehicles have gradually become an important trend in the automotive industry. Compared with traditional vehicles, intelligent connected vehicles integrate advanced information technology, communication technology, and control technology, enabling vehicles to effectively interact and coordinate with each other, roads, and pedestrians, significantly improving road safety. As a core component of the automotive electronic and electrical architecture, the vehicle area controller covers multiple aspects such as data interaction, signal control, and power distribution. It plays a crucial role in vehicle power, sensor management, and infotainment, and provides strong support for the stable operation and efficient collaboration of intelligent connected vehicles through efficient data processing, signal control, and power distribution. With continuous technological advancements and increasing application demands, the vehicle area controller will play an even more important role in the future development of intelligent connected vehicles.

[0003] However, the existing vehicle area controller structure has poor waterproof and electrostatic protection capabilities, which cannot guarantee the stable operation of the vehicle area controller in harsh environments. It is also easy for water to seep into the vehicle area controller, causing damage to the vehicle area controller. Summary of the Invention

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art where the existing vehicle area controller structure has poor waterproof and electrostatic protection capabilities, which leads to damage to the vehicle area controller.

[0005] Therefore, this utility model provides a vehicle area controller structure, including: a first housing, a circuit board, and a second housing. The circuit board is disposed between the first housing and the second housing. The second housing is connected to the first housing and the circuit board by a fastener. The second housing is provided with a protective plate extending toward the first housing in the circumferential direction. The protective plate surrounds the circuit board and the first housing in the circumferential direction.

[0006] In use, the circuit board is mounted on the side of the first housing near the second housing. The first housing and the circuit board are assembled together onto the second housing. A protective plate on the second housing surrounds the circuit board and the first housing circumferentially, causing the circuit board to be completely embedded within the second housing, forming an underbody structure. This enhances waterproofing and ESD protection, preventing external static electricity from damaging the circuit board. The automotive area controller structure provided by this invention solves the defects of existing vehicle area controller structures, which suffer from poor waterproofing and electrostatic discharge protection, leading to damage to the vehicle area controller.

[0007] Optionally, the first housing has multiple fixing holes, the inner side of the second housing has multiple fixing slots, and the circuit board has through holes. Fixing members pass through the fixing holes and through holes sequentially and connect to the fixing slots. This configuration achieves a three-in-one fixing method, ensuring the fit strength between the first and second housings. Furthermore, since all fixing holes are located on the first housing, and the back of the second housing has no openings, it effectively prevents water droplets from entering, enhancing the waterproof effect.

[0008] Optionally, the fixing groove is provided with a plurality of first ribs in the circumferential direction. By configuring it in this way, the first ribs can enhance the stability of the fixing groove, thereby improving the fit strength between the first housing and the second housing.

[0009] Optionally, a protective member is provided circumferentially around the fixing hole, and the protective member extends away from the circuit board so that it is higher than the end face of the first housing. With this arrangement, the protective member can, on the one hand, prevent water droplets from entering the first housing through the fixing hole, and on the other hand, increase the ESD protection effect of the screw-driving fixture, preventing static electricity from damaging the circuit board.

[0010] Optionally, a positioning post is provided on the side of the first housing near the circuit board, and a positioning hole is provided on the circuit board for the positioning post to pass through. A positioning groove is provided on the inner side of the second housing, and the positioning post passes through the positioning hole and is inserted into the positioning groove. With the above arrangement, the circuit board is mounted on the first housing through the positioning post and positioning hole, and then the first housing and the circuit board are assembled together onto the second housing. The positioning post is inserted into the positioning groove on the inner side wall of the second housing, which can position and fix the circuit board, preventing the circuit board from shaking within the first and second housings.

[0011] Optionally, both the first housing and the second housing have multiple pressure plates on the side near the circuit board. These pressure plates are used to press and position the circuit board on both sides. With this arrangement, the pressure plates inside the first and second housings press the circuit board firmly, further limiting and fixing the circuit board to prevent wobbling.

[0012] Optionally, the first housing is provided with multiple snap-fit ​​components circumferentially, and the inner sidewall of the protective plate is provided with multiple snap-fit ​​interfaces. The snap-fit ​​components are snapped into the snap-fit ​​interfaces. With this configuration, the snap-fit ​​components of the first housing are embedded in the snap-fit ​​interfaces of the protective plate, achieving a snap-fit ​​connection between the first housing and the protective plate. This ensures that the protective plate provides circumferential protection to the first housing, allowing the circuit board to be completely embedded within the second housing, thereby enhancing waterproofing and ESD protection capabilities.

[0013] Optionally, at least one mounting ear is provided on the outer side wall of the second housing, and the mounting ear has a mounting hole. With the above configuration, a fastener is installed in the mounting hole of the mounting ear, which can fix the second housing to the vehicle body.

[0014] Optionally, the mounting ear includes: a mounting plate disposed on the outer side wall of the second housing, with the mounting hole disposed on the mounting plate; and a second rib disposed between the mounting plate and the outer side wall of the second housing. With the above configuration, fasteners pass through the mounting hole on the mounting plate for secure installation, and the second rib strengthens the connection between the mounting plate and the second housing, thereby increasing the strength of the mounting ear and ensuring a reliable connection between the second housing and the vehicle body environment.

[0015] Optionally, the mounting ear is manufactured using insert injection molding. With this configuration, the mounting ear can withstand a torque of (8±1) N·m, ensuring a reliable connection between the second housing and the vehicle body environment. Attached Figure Description

[0029] This embodiment provides an automotive area controller structure that can improve waterproofing and ESD protection performance, ensuring stable operation of the controller in highly integrated functions and harsh environments.

[0030] As shown in Figures 1 and 2, this embodiment provides a specific implementation of a vehicle area controller structure, including: a first housing 1, a circuit board 2, and a second housing 3. The circuit board 2 is disposed between the first housing 1 and the second housing 3. The second housing 3 is connected to the first housing 1 and the circuit board 2 by a fastener 4. The second housing 3 is provided with a protective plate 31 extending toward the first housing 1 in the circumferential direction. The protective plate 31 surrounds the circuit board 2 and the first housing 1 in the circumferential direction.

[0031] In use, the circuit board 2 is mounted on the side of the first housing 1 near the second housing 3. The first housing 1 and the circuit board 2 are assembled together onto the second housing 3. The protective plate 31 on the second housing 3 surrounds the circuit board 2 and the first housing 1 circumferentially, so that the circuit board 2 is completely embedded in the second housing 3, forming an underbody structure. This enhances waterproofing and ESD protection, preventing external static electricity from damaging the circuit board 2. The vehicle area controller structure provided in this embodiment solves the defects in the prior art where the poor waterproofing and electrostatic protection of existing vehicle area controller structures leads to damage to the vehicle area controller.

[0032] As shown in Figures 1-6, in the vehicle area controller structure provided in this embodiment, the first housing 1 is provided with multiple fixing holes 11, the inner side of the second housing 3 is provided with multiple fixing grooves 32, and the circuit board 2 is provided with through holes 21. Fixing members 4 pass through the fixing holes 11 and through holes 21 sequentially and connect to the fixing grooves 32. The fixing members 4 implement a three-in-one fixing method, which can ensure the fit strength between the first housing 1 and the second housing 3. Furthermore, all fixing holes 11 are located on the first housing 1, and the back of the second housing 3 has no openings, effectively preventing water droplets from entering and enhancing the waterproof effect. Alternatively, as an alternative embodiment, the fixing holes 11 and the fixing grooves 32 are arranged around the circumference of the circuit board 2, and the through holes 21 on the circuit board 2 are omitted.

[0033] Specifically, the fixing member 4 is configured as a screw, and the fixing member 4 is threadedly connected to the fixing groove 32.

[0034] As shown in Figure 5, in the vehicle area controller structure provided in this embodiment, the fixing groove 32 is provided with a plurality of first ribs 321 in the circumferential direction. The first ribs 321 can enhance the stability of the fixing groove 32, thereby improving the fit strength between the first housing 1 and the second housing 3. In addition, as an alternative embodiment, the first ribs 321 can be omitted, and the thickness of the sidewall of the fixing groove 32 can be increased.

[0035] As shown in Figures 1-4, in the vehicle area controller structure provided in this embodiment, a protective member 12 is circumferentially provided on the fixing hole 11. The protective member 12 extends away from the circuit board 2, so that the protective member 12 is higher than the end face of the first housing 1. The protective member 12 can prevent water droplets from entering the first housing 1 through the fixing hole 11, and can also increase the ESD protection effect of the screw-driving fixture, preventing static electricity from damaging the circuit board 2. In addition, as an alternative embodiment, the protective member 12 can be omitted, and a removable protective cover can be provided on the fixing hole 11.

[0036] As shown in Figures 2-5, in the vehicle area controller structure provided in this embodiment, a positioning post 13 is provided on the side of the first housing 1 near the circuit board 2.

The positioning post 13 passes through the positioning hole 22 and is inserted into the positioning groove 33. The circuit board 2 is mounted on the first housing 1 through the positioning post 13 and the positioning hole 22. Then, the first housing 1 and the circuit board 2 are assembled together onto the second housing 3. The positioning post 13 is inserted into the positioning groove 33 on the inner side wall of the second housing 3, which can position and fix the circuit board 2, preventing the circuit board 2 from shaking within the first housing 1 and the second housing 3. Alternatively, as an alternative embodiment, the positioning post 13 can be provided on the inner side wall of the second housing 3, and the positioning groove 33 can be provided on the inner side wall of the first housing 1.

[0037] As shown in Figures 2-5, in the vehicle area controller structure provided in this embodiment, multiple pressure plates are provided on the side of the first housing 1 and the second housing 3 near the circuit board 2. These pressure plates are used to press and position the two sides of the circuit board 2. The pressure plates on the inner sides of the first housing 1 and the second housing 3 press the circuit board 2, further limiting and fixing it to prevent shaking. Alternatively, as an alternative implementation, the pressure plates can be omitted, and the circuit board 2 can be pressed by the root of the positioning post 13 and the upper end of the positioning groove 33.

[0038] As shown in Figures 2-5, in the vehicle area controller structure provided in this embodiment, the first housing 1 has multiple snap-fit ​​pieces 14 arranged circumferentially, and the inner wall of the protective plate 31 has multiple snap-fit ​​interfaces 34. The snap-fit ​​pieces 14 are snapped into the snap-fit ​​interfaces 34. The snap-fit ​​pieces 14 of the first housing 1 are embedded in the snap-fit ​​interfaces 34 of the protective plate 31, realizing the snap-fit ​​connection between the first housing 1 and the protective plate 31. This ensures that the protective plate 31 provides circumferential protection for the first housing 1, allowing the circuit board 2 to be completely embedded in the second housing 3, thereby enhancing waterproof and ESD protection capabilities. Alternatively, as an alternative implementation, the snap-fit ​​pieces 14 can be disposed on the inner wall of the protective plate 31, and the snap-fit ​​interfaces 34 can be disposed circumferentially on the housing.

Fasteners pass through the mounting hole 352 on the mounting plate 351 for fixed installation. The second rib 353 can strengthen the connection between the mounting plate 351 and the second housing 3, thereby improving the strength of the mounting ear 35 and ensuring a reliable connection between the second housing 3 and the vehicle body environment. Alternatively, as an alternative embodiment, the second rib 353 can be omitted, and a diagonal brace can be provided between the mounting plate 351 and the second housing 3.

[0041] As shown in Figures 1, 2, 5, and 6, in the vehicle area controller structure provided in this embodiment, the mounting ear 35 is manufactured using insert injection molding. The mounting ear 35 can withstand a torque of (8±1) N·m, ensuring a reliable connection between the second housing 3 and the vehicle body environment.
