Existing model car subframe mounting bracket structure (such as Figure 5 ) is composed of the original sub-frame mounting bracket 21, the original sub-frame 22, the original longitudinal beam rear section 24, and the original front floor 25. The disadvantage of this existing sub-frame mounting bracket structure is that the strength is relatively weak, and the In the event of a frontal collision or an offset collision, the rear section of the original longitudinal beam will be bent due to the large collision force F transmitted from the front end, resulting in a large intrusion of the front wall panel, which will affect the safety of the occupants

The invention relates to a mounting bracket structure of an automobile auxiliary frame; the mounting bracket structure comprises an auxiliary frame mounting bracket, and an auxiliary frame, a floor middle longitudinal beam, a longitudinal beam rear section and a front floor which are respectively connected with the auxiliary frame mounting bracket; the mounting bracket structure is characterized in that the cross section of the auxiliary frame mounting bracket is in a 'Z' shape; the straight surface of the lower part of the auxiliary frame mounting bracket has a through hole; and the auxiliary frame is matched with the through hole through a bolt, and is connected under the auxiliary frame mounting bracket. According to the mounting bracket structure, the auxiliary frame, the floor middle longitudinal beam and the longitudinal beam rear section are connected together by the auxiliary frame mounting bracket, and a path for dispersing the transfer of collision force can be formed by the auxiliary frame, the floor middle longitudinal beam and the longitudinal beam rear section, so that the problems that the longitudinal beam rear section is bended after collision, and the quantity of invasion to a front wall plate is large can be solved, and the operation stability and the comfort of passengers are improved.
Description
technical field [0001] The invention relates to an automobile body structure, in particular to an automobile auxiliary frame mounting bracket structure. Background technique [0002] The subframe is an important component of the automobile chassis. It not only needs to meet the installation requirements of related parts, but also needs to have sufficient strength and rigidity to ensure that no large deformation occurs when the load is transmitted in all directions, and to improve the overall performance of the automobile chassis. Thereby improving the handling stability of the vehicle. During the driving process of the car, the force and vibration from the road will be transmitted along the path of tire-control arm-subframe-body, and the final feedback will be the vibration of the body and the subjective feeling of the occupants; Part of the collision force is transmitted backwards from the subframe to the mounting bracket of the subframe, and the deformation of the bracket...
