The invention provides a vehicle body mounting point reinforcing structure, a mounting structure of a suspension bracket and a vehicle. The mounting point reinforcing structure comprises a supporting part, a reinforcing part and a mounting part, the supporting part is located in a groove formed in the vehicle body longitudinal beam inner plate, one end of the supporting part is connected with the side wall of the groove of the vehicle body longitudinal beam inner plate, and the other end of the supporting part is connected with the mounting part; the reinforcing part is fixed in a groove of the vehicle body longitudinal beam inner plate; the installation part penetrates through the side wall of the groove of the automobile body longitudinal beam inner plate and is used for installing automobile parts. The invention further provides an installation structure of the suspension support, the installation structure comprises the installation point reinforcing structure, and the suspension installation support is installed on an installation component; the inner side wall of the arc-shaped cavity of the suspension installation support is welded to the installation component, and the inner side bottom of the arc-shaped cavity is welded to the outer side wall of the groove of the automobile body longitudinal beam inner plate. The invention further provides a vehicle which comprises the mounting structure of the suspension bracket. The problem that in the prior art, the NVH performance of a vehicle is low due to the fact that the dynamic stiffness of an installation point on the vehicle body is low is solved.

    本发明提供了一种车身安装点加强结构、悬置支架的安装结构及车辆。安装点加强结构包括支撑部件、加强部件和安装部件,支撑部件位于车身纵梁内板形成的凹槽内,一端与车身纵梁内板的凹槽侧壁相连,另一端与安装部件相连;加强部件固定在车身纵梁内板的凹槽内;安装部件穿过车身纵梁内板的凹槽侧壁,并用于安装汽车零件。本发明还提供了一种悬置支架的安装结构,包括安装点加强结构,悬置安装支架安装在安装部件上;悬置安装支架的弧形腔体的内侧壁与安装部件焊接,内侧底部焊接在车身纵梁内板凹槽的外侧壁上。本发明还提供了一种车辆,包括悬置支架的安装结构。本发明解决了现有技术中车身上的安装点的动刚度低,导致车辆的NVH性能低的问题。
