The invention relates to the field of cross beam frameworks, and discloses an instrument cross beam framework added with a whole vehicle modal structure, which comprises a first cross beam, one end of the first cross beam is fixedly connected with a second front wall connecting point, the middle part of the first cross beam is fixedly clamped with a second cross beam, one end of the second cross beam is fixedly connected with a first front wall connecting point, and the other end of the second cross beam is fixedly connected with a second front wall connecting point. An instrument framework is fixedly connected to the middle of the first cross beam, and the first front wall connecting point and the second front wall connecting point are located on the two sides of the instrument framework respectively. Compared with the prior art, the structural rigidity of the instrument beam framework in use is improved, and the overall noise, vibration and sound vibration roughness performance of an automobile is improved.

    本发明涉及横梁骨架领域,公开了一种增加整车模态结构的仪表横梁骨架,包括第一横梁,所述第一横梁的一端固定连接有第二前围连接点,所述第一横梁的中部固定卡接有第二横梁,所述第二横梁的一端固定连接有第一前围连接点,所述第一横梁的中部固定连接有仪表骨架,所述第一前围连接点和所述第二前围连接点分别位于所述仪表骨架的两侧。相较于现有技术,本申请提升仪表横梁骨架使用时的结构刚度,使得汽车整体的噪声、振动与声振粗糙度的性能得到提升。
