The light guide part is designed to be of the structure that the at least two light guide sections and the connecting sections are alternately connected, independent segmented control over all the light guide sections can be achieved, for example, the on-off states of different light guide sections are independently adjusted, or differentiated color output of all the light guide sections is achieved, the problem that a traditional light guide part is single in light emitting effect is effectively solved, and the light guide part is more convenient to use. And diversified and differentiated light emitting requirements are fully met. The connecting sections can effectively limit light transmission between the adjacent light guide sections, and the light crosstalk phenomenon is avoided.

The utility model provides a radiator upper cross beam installation structure and a vehicle, and belongs to the technical field of vehicles, the radiator upper cross beam installation structure comprises a radiator upper cross beam installation plate, a radiator upper cross beam installation conversion support and a radiator upper cross beam assembly, the radiator upper cross beam installation conversion support is connected to the radiator upper cross beam installation plate through a first bolt; the radiator upper cross beam assembly is connected to the radiator upper cross beam mounting conversion bracket through a second bolt; radiator upper cross beam mounting plates and radiator upper cross beam mounting conversion brackets are arranged at the left end and the right end of the radiator upper cross beam assembly; a first adjusting hole set allowing the first bolt to penetrate through and a second adjusting hole set allowing the second bolt to penetrate through are formed in the radiator upper cross beam installation conversion support. Due to the fact that the radiator upper cross beam installation conversion support is adopted as middle conversion, assembly tolerance accumulated in a cabin is absorbed, a size assembly chain is shortened, the matching precision of a cabin front bumper and a machine cover can be guaranteed, and the visibility of the front appearance of a whole vehicle is improved.
