Opening the car door and entering the vehicle, the first thing that catches the eye is the instrument panel, some exuding a high-tech feel, others avant-garde and stylish. Beneath these diverse instrument panels lies a supporting structure-the instrument panel crossbeam, or CCB (Car Cross Beam).
The CCB primarily supports the human-machine interface control equipment and decorative components, while also forming a safety system in conjunction with other safety structures. Its structure is simple, mainly consisting of a tubular beam, side supports, a column mounting bracket assembly, lower support legs, and auxiliary supports. The instrument panel crossbeam is installed at the front of the cab, hidden beneath the instrument panel, and is used to secure the instrument panel and its accessories; therefore, the CCB is often developed as part of the vehicle's interior and exterior trim. Furthermore, the CCB is mostly a metal structure, spanning both sides of the vehicle body, reinforcing the entire cab. Structures such as the PAB (Passenger Air Bag) are also installed on it, requiring a certain level of strength; therefore, the CCB is also designed as a structural load-bearing component. As a supporting component under the front instrument panel, the CCB bears the important responsibility of installation and safety support.
