Lower bracket assembly of car radiator

Abstract

The invention discloses a lower bracket assembly of a car radiator, which comprises a bracket body on which two flanging holes are arranged, and is characterized in that: the section of the bracket body is shaped like a Chinese character 'ji', and a middle strengthening part is connected with the undersurface of the bracket body; the left end of the bracket body is connected with a left connecting piece external plate bending upwards, and the section of the left connecting piece external plate is shaped like a Chinese character 'ji'; the left side of the left connecting piece external plate is connected with a left connecting piece internal plate, and the right end of the bracket body is connected with a right connecting piece external plate bending upwards; and the section of the right connecting piece external plate is shaped like a Chinese character 'ji', and the right side of the right connecting piece external plate is connected with a right connecting piece internal plate. The whole force transfer structure of the invention is more continuous and complete, and greatly improves the torsional rigidity of a front car body, thereby improving the performance and driving comfort of the whole car and being difficult to generate the phenomena that the radiator is unstably installed or generates abnormal sound; and the radiator can be installed from top to bottom, and the operation is more labor-saving.

Description

technical field [0001] The invention relates to automobile components, in particular to a car radiator lower bracket assembly. Background technique [0002] The lower bracket of the radiator of a car is an important component of the engine compartment. In terms of function, due to the limited space in the front cabin of a car, radiators, condensers, intercoolers, front bumper snap points, and washing kettles of some models are all installed on the lower bracket of the radiator. Structurally, the radiator lower bracket is an important part connecting the front body, which has an important influence on the welding accuracy of the front body and the torsional mode of the front body, and the torsional mode of the front body directly affects the Driving comfort in the crew cabin. In addition, the radiator lower bracket also plays a certain role in improving the front crash performance of the car body. Therefore, the rationality and scientificity of its structure should be full...

AI Technical Summary

Problems solved by technology

Since the radiator is installed on the body from bottom to top, in the assembly workshop, a high station must be used when installing the radiator, and the operation is more difficult

Secondly, since the lower bracket of the radiator and the body are in the form of assembly, the connection point is only one piece, which causes the rigidity of the radiator installation point to be very poor, which may cause the radiator to be installed loosely or have abnormal noises.
