Description

Technical Field

[0001] The utility model relates to the field of ADAS domain controllers, and in particular to a waterproof structure of an ADAS domain controller. Background Art

[0002] The ADAS domain controller is responsible for integrating and processing data from multiple sensors to implement a series of driving assistance functions, including adaptive cruise control, automatic emergency braking, lane keeping assist, blind spot monitoring, automatic parking, etc.

[0003] At present, ADAS domain controllers are arranged according to the requirements of the whole vehicle. Generally, ADAS domain controllers are arranged inside the vehicle body. If water or other liquids enter the controller, it is easy to cause short circuit and corrosion of electronic components, which will endanger the operation safety of the entire ADAS domain controller. Therefore, it is necessary to design a waterproof function in the vehicle body environment. To achieve the waterproof function of the ADAS domain controller, there are only two options: one is to strengthen the waterproof characteristics of the ADAS domain controller itself, and the other is to strengthen the sealing of the vehicle body shell.

[0004] However, the patent application with announcement number CN217608125U proposed in the prior art has a better sealing effect on the edge after the upper cover and the bottom plate are assembled through the design of the edge groove of the upper cover and the elastic sealing part on the bottom plate, which is beneficial to prevent the entry of liquid. At the same time, the design of the integrated connecting groove can form a diversion effect for the liquid, especially after the controller is installed and used, the liquid that penetrates from the outside can be diverted to the two ends through the groove, and then flow out through the leakage holes opened on both sides, avoiding accumulation and affecting the components, further enhancing the overall waterproof performance, effectively protecting the internal components, reducing the risk of damage to the controller, and improving safety.

[0005] However, current ADAS domain controllers install elastic gaskets inside for sealing in order to prevent water from seeping out. However, this method can only perform a single sealing operation and cannot block water when the gasket is damaged.

[0006] Therefore, it is necessary to provide an ADAS domain controller waterproof structure to solve the above technical problems. Utility Model Content

[0007] The utility model provides an ADAS domain controller waterproof structure, which solves the problem that the existing ADAS domain controller installs an elastic sealing gasket inside for sealing operation in order to prevent water, but this method can only perform a single sealing operation and cannot block water when the sealing gasket is damaged.

[0008] In order to solve the above technical problems, the utility model provides an ADAS domain controller waterproof structure, including:

[0009] A housing, wherein a circuit board is disposed inside the housing and a housing cover is disposed on the top of the housing;

[0010] a first sealing assembly, the first sealing assembly being disposed between the housing and the housing cover;

[0011] The second sealing component is arranged between the shell and the shell cover, and the second sealing component includes a first fixing frame and a second fixing frame. The bottom of the second fixing frame is connected with a rectangular sealing gasket, and the surface of the first fixing frame is provided with a rectangular sealing groove adapted to the rectangular sealing gasket.

[0012] Preferably, the first sealing assembly includes a sealing gasket, and a sealing groove matched with the sealing gasket is formed on the surface of the shell.

[0013] Preferably, a plurality of through holes are provided between the first fixing frame and the second fixing frame.

[0014] Preferably, the sealing gasket and the sealing groove and the rectangular sealing gasket and the rectangular sealing groove are used for multiple sealing between the shell and the shell cover.

[0015] Preferably, a protective component is arranged on the side of the shell, and the protective component includes a protective cover, a rectangular through hole is opened at the center of the surface of the protective cover, and a plurality of circular through holes are opened on the surface of the protective cover and on the left and right sides of the rectangular through hole.
