This application relates to a bracket assembly, a windshield assembly, and a vehicle. When an optical element is assembled on the bracket body or removed, the limiting member is in a loosened position, and each abutment part and clamping arm is separated from each other. When the fixed shaft is inserted between the two clamping arms, it can push the two clamping arms apart. When the fixed shaft is pulled out of the two clamping arms, it can also push the two clamping arms apart. When the optical element is inserted between the two clamping arms, the limiting member is in a pressed position, and each abutment part abuts against each clamping arm, so that the two clamping arms are tightly abutted against the opposite sides of the fixed shaft. This ensures that the insertion force of the optical element is small and the extraction force is large during the assembly process. In addition, the tension of the retaining spring remains unchanged, and the extraction force between the retaining spring and the fixed shaft is stable over a long period of time. Furthermore, the interference fit between the retaining spring and the fixed shaft can be reduced to reduce the insertion force.
