Description

Technical Field

[0001] This utility model discloses a vehicle body controller, which belongs to the field of automotive electronics. Background Technology

[0002] In the field of automotive electronics, the body controller, as one of the core components of a vehicle's electronic system, needs to be installed in a specific location within the vehicle to control various electrical devices. Due to the complex operating environment of vehicles, body controllers typically require a certain degree of sealing to prevent external dust, moisture, and other contaminants from intruding into the internal electronic components and affecting their normal operation. However, the electronic components inside the controller generate heat during operation, and changes in the external ambient temperature can also cause pressure differences between the inside and outside of the controller housing. If the housing is completely sealed, pressure imbalances may lead to housing deformation or a decrease in sealing performance, thereby affecting the stability and lifespan of the internal components.

[0003] The existing ventilation structure design of the vehicle body controller often has shortcomings. For example, the layout of the waterproof and breathable components and the internal circuit board (PCBA board) is unreasonable, which may lead to poor ventilation or dust and moisture directly contacting electronic components through the ventilation channel. Utility Model Content

[0004] The purpose of this invention is to solve the problem of poor waterproof and breathable performance of existing vehicle body controllers, and to propose a new type of vehicle body controller.

[0005] The problem to be solved by this utility model is achieved by the following technical solution: A vehicle body controller includes: a controller housing with a mounting cavity; a waterproof and breathable component disposed within the mounting cavity and connected to the controller housing, the waterproof and breathable component being used to connect the mounting cavity to the outside air; a PCBA board disposed within the mounting cavity, the PCBA board being spaced apart from the waterproof and breathable component; a connecting component connecting the controller housing to the vehicle body; and a plug-in component electrically connected to the PCBA board and connected to the controller housing, the plug-in component being spaced apart from the waterproof and breathable component.

[0006] Furthermore, the controller housing includes: a housing body having an installation cavity, a waterproof and breathable component connected to the housing body, and a plug-in component connected to the housing body; a cover detachably connected to the housing body, having a working position that mates with the housing body and a separating position that separates from the housing body; a limiting component disposed within the installation cavity, connected to the housing body, spaced apart from the waterproof and breathable component, and connected to the PCBA board; and a housing connecting component connected to the housing body and connected to the vehicle body via a connecting component.

[0007] Furthermore, the limiting component includes: multiple support columns spaced apart and connected to the shell body; multiple limiting cylinders spaced apart, at least some of the limiting cylinders having support columns, and the multiple limiting cylinders cooperating with the PCBA board for limiting; and multiple limiting plates spaced apart, at least some of the support columns having limiting plates, and the multiple limiting plates cooperating with the PCBA board for limiting.

[0008] Furthermore, the housing connection assembly includes: a first connecting ear, which is connected to the housing body and has a first connecting hole; and a second connecting ear, which is spaced apart from the first connecting ear and is connected to the housing body, and has a second connecting hole and a third connecting hole.

[0009] Furthermore, the connecting assembly includes: a first positioning post, the first end of which engages with a first connecting hole and is connected to the vehicle body via a first bolt; and a second positioning post, which engages with a second connecting hole and a third connecting hole respectively and is connected to the vehicle body via a second bolt.

[0010] Furthermore, the waterproof and breathable component includes: a breathable tube, which is disposed in the mounting cavity and connected to the shell body, the breathable tube having a ventilation channel, the first vent of the breathable tube being connected to the shell body, and the second vent of the breathable tube being connected to the mounting cavity; and a waterproof and breathable structure, which is sealed to the second vent of the breathable tube and spaced apart from the PCBA board.

[0011] Furthermore, the controller housing also includes: a first protrusion, which is connected to the opening of the housing body; and a first recess, which is connected to the inner edge of the cover body, wherein the first protrusion and the first recess are detachably connected.

[0012] Furthermore, the controller housing also includes: positioning posts, which are multiple and spaced apart. Each positioning post is connected to the inner side of the cover. When the cover is in the working position, the multiple positioning posts cooperate with the PCBA board for positioning.

[0013] The advantages of this invention compared to existing technologies are as follows: This utility model provides a vehicle body controller. By setting a ventilated component in the mounting cavity of the controller housing, the mounting cavity is connected to the outside air. This not only balances the air pressure inside and outside the housing, preventing damage to the housing or failure of the seal due to air pressure difference, but also prevents dust, moisture and other substances from entering through a reasonable structural design, protecting the internal components. The PCBA board and the ventilated component are set apart to prevent impurities that may be introduced during the ventilation process from directly contacting the electronic components, while reducing mutual interference between the two and improving the stability and reliability of the PCBA board.

[0023] like Figures 1-3 As shown, the first embodiment of this utility model provides a vehicle body controller based on the prior art, including: a controller housing, a waterproof and breathable component 20, a connecting component, a PCBA board 80, and a plug-in component 10. The controller housing is provided with an installation cavity 312. The waterproof and breathable component 20 is disposed in the installation cavity 312 and connected to the controller housing 30. The waterproof and breathable component 20 is used to connect the installation cavity 312 with the outside air. The PCBA board 80 is disposed in the installation cavity 312 and is spaced apart from the waterproof and breathable component 20. The controller housing is connected to the vehicle body through the connecting component. The plug-in component 10 is electrically connected to the PCBA board 80 and connected to the controller housing. The plug-in component 10 is spaced apart from the waterproof and breathable component 20.

[0024] In this embodiment, the controller housing is provided with a mounting cavity 312, which provides a stable mounting space for components such as the waterproof and breathable assembly 20 and the PCBA board 80, ensuring the orderly assembly of each component. The waterproof and breathable assembly 20 is disposed within the mounting cavity 212 and connected to the controller housing 30, allowing the mounting cavity 312 to communicate with the outside air. While balancing the air pressure inside and outside the mounting cavity 312, it effectively prevents external moisture, dust, and other contaminants from entering, protecting the internal components.

The controller housing is connected to the vehicle body via a connecting assembly, ensuring a stable and reliable connection that can adapt to the vibration environment during vehicle operation and guaranteeing the overall stability of the vehicle body controller installation. The plug-in component 10 is electrically connected to the PCBA board 80 and the controller housing, achieving stable electrical transmission. At the same time, it is spaced apart from the waterproof and breathable component 20 to avoid mutual interference and ensure that each of them functions properly.

[0025] Furthermore, the controller housing includes: a housing body 310, a cover 313, a limiting component, and a housing connecting component. The housing body 310 is provided with an installation cavity 312. The waterproof and breathable component 20 is connected to the housing body 310. The plug-in component 10 is connected to the housing body 310. The cover 313 is detachably connected to the housing body 310. The cover 313 has a working position that cooperates with the housing body 310, and a separation position that separates it from the housing body 310. The limiting component is disposed in the installation cavity 312 and is connected to the housing body 310. The limiting component is spaced apart from the waterproof and breathable component 20 and is connected to the PCBA board 80. The housing connecting component is connected to the housing body 313 and is connected to the vehicle body through a connecting component.

[0026] In this embodiment, the housing body 310 is provided with an installation cavity 312, which provides an installation base for components such as the waterproof and breathable component 20 and the PCBA board 80. Both the waterproof and breathable component 20 and the plug-in component 10 are connected to the housing body 310, ensuring the stability of each component's installation. The cover 313 is detachably connected to the housing body 310, allowing it to switch between a working position and a separated position. In the working position, it cooperates with the housing body 310 to form a closed space to protect the internal components. In the separated position, it facilitates the inspection and replacement of components within the installation cavity 312, improving maintenance convenience. The limiting component is located within the installation cavity 312 and connected to the housing body 310, as well as the PCBA board 80. It effectively fixes the PCBA board 80, preventing it from shaking during vehicle operation and ensuring operational stability. Furthermore, the limiting component and the waterproof and breathable component 20 are spaced apart to avoid mutual interference.

[0027] In this embodiment, as Figure 4 As shown, the limiting component includes: support columns 311, limiting cylinders 302, and limiting plates 301. Multiple support columns 311 are spaced apart and connected to the shell body 310. Multiple limiting cylinders 302 are spaced apart, with at least a portion of the limiting cylinders 302 having support columns 311. The multiple limiting cylinders 302 cooperate with the PCBA board 80 for limiting. Multiple limiting plates 301 are spaced apart, with at least a portion of the support columns 311 having limiting plates 301. The multiple limiting plates 301 cooperate with the PCBA board 80 for limiting.

[0028] In this embodiment, multiple support columns 311 are spaced apart and connected to the shell body 310, providing stable installation support for the limiting cylinders 302 and limiting plates 301. The spaced design avoids excessive occupation of the internal space of the mounting cavity 312, facilitating the layout of other components. The multiple limiting cylinders 302, spaced apart and at least partially integrated with the support columns 311, can limit the PCBA board 80 from multiple points through cooperation with it, enhancing the stability of the PCBA board 80 installation and preventing displacement during vehicle vibration. The multiple limiting plates 301, spaced apart and at least partially integrated with the support columns 311, limit the PCBA board 80 from a planar dimension through their plate-like structure and cooperation with it, complementing the limiting cylinders 302 and further improving the limiting effect. The combined design of the support column 311, the limiting column 302, and the limiting plate 301, through a multi-limiting method combining points and surfaces, comprehensively ensures the positional stability of the PCBA board 80 within the mounting cavity 312, ensuring its reliable relative positional relationship with other components, which is conducive to the stable performance of the overall function of the body controller.

[0029] In one exemplary embodiment, the housing connection assembly includes a first connecting ear 309 and a second connecting ear 305. The first connecting ear 309 is connected to the housing body 310 and has a first connecting hole 308. The second connecting ear 305 is spaced apart from the first connecting ear 309 and is connected to the housing body 310. The second connecting ear 305 has a second connecting hole 306 and a third connecting hole 307. The first connecting ear 309, connected to the housing body 310, provides a stable connection point for the connection between the housing and the vehicle body through the first connecting hole 308, ensuring the basic reliability of the connection. The second connecting ear 305, connected to the housing body 310 and spaced apart from the first connecting ear 309, allows the housing body 310 to be fixed from different positions through the cooperation of the two connecting ears, improving the balance and overall stability of the housing installation. The second connecting ear 305 is provided with a second connecting hole 306 and a third connecting hole 307, which increases the selection of connection points and can adapt to the installation requirements of different vehicle bodies or different specifications of connecting parts, thereby improving the versatility of the component. The spaced layout of the first connecting ear 309 and the second connecting ear 305, combined with their respective connecting hole designs, can effectively disperse the stress generated by vibration during vehicle operation, reduce damage to the connection structure, and ensure long-term stability.

[0030] In this embodiment, the connecting assembly includes a first positioning post 70 and a second positioning post 50. The first end of the first positioning post 70 mates with the first connecting hole 308 and is connected to the vehicle body via a first bolt 60. The second positioning post 50 mates with the second connecting hole 306 and the third connecting hole 307 respectively and is connected to the vehicle body via a second bolt 40. The precise mating of the first end of the first positioning post 70 with the first connecting hole 308 and the first bolt 60 to the vehicle body ensures accurate positioning of the housing connecting assembly and the vehicle body, guaranteeing the precision of the installation position. Simultaneously, the bolted connection ensures the stability of the connection. The second positioning post 50 can mate with the second connecting hole 306 and the third connecting hole 307 respectively and is connected to the vehicle body via a second bolt 40, providing flexible connection options for housing installation, adapting to different installation scenarios and vehicle structures, and improving the adaptability of the connection. The first positioning post 70 and the second positioning post 50 correspond to different connecting ears and connecting holes, forming a multi-point connection structure. This structure can better disperse the force caused by vibration during vehicle operation, enhancing the overall vibration resistance of the connection. The connection method combining positioning posts and bolts achieves both pre-installation positioning through the positioning posts for convenient installation and secure connection through the bolts, ensuring connection reliability during long-term use, thus balancing installation efficiency and structural stability.

[0031] In one exemplary embodiment, the waterproof and breathable component 20 includes: a breathable pipe 204 and a waterproof and breathable structure 201. The breathable pipe 204 is disposed in the mounting cavity 312 and connected to the housing body 310. The breathable pipe 204 is provided with a ventilation channel. The first vent 202 of the breathable pipe 204 is connected to the housing body 310, and the second vent 203 of the breathable pipe 204 is connected to the mounting cavity 312. The waterproof and breathable structure 201 is sealed to the second vent 203 of the breathable pipe 204, and the waterproof and breathable structure 201 is spaced apart from the PCBA board 80.

[0032] In this embodiment, the combined design of the vent pipe 204 and the waterproof and breathable structure 201 allows for air circulation between the mounting cavity 312 and the outside environment through the ventilation channel of the vent pipe 204 to balance air pressure, while effectively preventing moisture from entering through the waterproof and breathable structure 201. This achieves the dual functions of waterproofing and breathability, ensuring the safety of internal components. The first vent 202 of the vent pipe 204 is connected to the shell body 310, and the second vent 203 is connected to the mounting cavity 312, forming a clear and orderly gas flow path and ensuring breathability efficiency. The waterproof and breathable structure 201 and the second vent 203 of the vent pipe 204 are sealed together, enhancing the reliability of waterproofing performance and preventing moisture from entering the mounting cavity 312 through the connection gap. The waterproof and breathable structure 201 is spaced apart from the PCBA board 80 to prevent condensation or impurities that may be generated during the breathability process from directly contacting the electronic components on the PCBA board 80, reducing the impact on its working stability, and avoiding structural interference between the two.

[0033] Furthermore, such as Figure 5 As shown, the controller housing also includes a first protrusion 304 and a first recess 314. The first protrusion 304 connects to the opening of the housing body 310, and the first recess 314 connects to the inner edge of the cover 313. The first protrusion 304 and the first recess 314 are detachably connected. The connection between the first protrusion 304 and the opening of the housing body 310, and the connection between the first recess 314 and the inner edge of the cover 313, provides a precise positioning structure for the connection between the housing body 310 and the cover 313, ensuring that the cover 313 can accurately align with the housing body 310 in the working position, thus improving assembly accuracy. The detachable connection between the first protrusion 304 and the first recess 314 ensures the stability of the connection between the housing body 310 and the cover 313, and also facilitates switching the cover 313 to the separated position when needed, providing convenience for the inspection and maintenance of the internal components of the mounting cavity 312. This convex-concave fit connection enhances the sealing performance between the shell body 310 and the cover 313, reducing the possibility of external dust and moisture entering the mounting cavity 312 through the connection point, thus further protecting the internal components. The simple structural design eliminates the need for complex connectors, ensuring effective connection while reducing manufacturing costs and improving assembly efficiency.

[0034] In one exemplary embodiment, the controller housing further includes: positioning posts 303, comprising multiple positioning posts 303 arranged at intervals, each positioning post 303 being connected to the inner side of the cover 313. When the cover 313 is in the working position, the multiple positioning posts 303 cooperate with the PCBA board 80 for positioning. The multiple positioning posts 303, arranged at intervals and connected to the inner side of the cover 313, can cooperate with the PCBA board 80 for positioning when the cover 313 is in the working position, further limiting the PCBA board 80 from one side of the cover, and forming a coordinated upper and lower fixation with the limiting components in the mounting cavity 312. This significantly improves the positional stability of the PCBA board 80 within the mounting cavity 312, effectively preventing the PCBA board 80 from shaking or shifting during vehicle travel vibrations. The connection design between the positioning posts 303 and the cover 313 utilizes the working position of the cover 313 to achieve the positioning function of the PCBA board 80, eliminating the need for an additional independent positioning structure, resulting in a more compact overall layout and full utilization of the internal space of the housing. The spaced arrangement of multiple positioning posts 303 can adapt to the positioning needs of different areas of the PCBA board 80, ensuring more comprehensive and accurate positioning of the PCBA board 80 and avoiding damage to the PCBA board 80 due to excessive local stress. When the cover 313 is switched to the separated position, the positioning posts 303 disengage from the PCBA board 80 along with the cover 313, without obstructing the inspection and maintenance operations of the components inside the mounting cavity 312, thus balancing positioning function and operational convenience.

[0035] The second embodiment of this utility model provides a vehicle based on the first embodiment, including a vehicle body and the aforementioned body controller.

[0036] In this embodiment, the vehicle includes the aforementioned body controller. The body controller is securely connected to the vehicle body via connecting components, enabling stable operation in complex driving environments. This provides reliable control for various electrical devices within the vehicle, improving the overall stability of the vehicle's electronic system. The waterproof and breathable component 20 of the body controller balances the air pressure inside and outside the mounting cavity 312, preventing damage to the housing and blocking moisture and dust intrusion. Combined with other protective structures, this allows the body controller to adapt to diverse environments such as rain, snow, and mud, extending the lifespan of the vehicle's electronic components and reducing maintenance costs. The PCBA board 80 inside the body controller is stably fixed using limiting components and positioning posts 303, reducing the impact of vibration and ensuring stable transmission of control signals. This contributes to the precise execution of various vehicle functions (such as lighting and window / door control), improving vehicle safety and comfort. The components of the body controller are rationally arranged, facilitating installation and maintenance. When the vehicle requires maintenance of the body controller, it can be efficiently completed by removing the cover 313, reducing maintenance time and improving vehicle efficiency.
