1. A windshield wiper assembly, comprising: a support arm having a connecting portion; and a wiper unit connected with the connecting portion of the support arm; wherein: the wiper unit includes: a blade having a central portion provided with a mounting seat; a resilient wiper connected with the blade; a movable bracket movably mounted in the mounting seat of the blade; at least one support pin secured on the mounting seat of the blade and extended through the movable bracket; and at least one pair of elastic members each mounted in the mounting seat of the blade and each biased between the mounting seat of the blade and the movable bracket; the mounting seat of the wiper unit has an interior provided with a receiving chamber; the movable bracket of the wiper unit is received in the receiving chamber of the mounting seat and is connected with the connecting portion of the support arm; the movable bracket of the wiper unit has two opposite sidewalls each provided with at least one through hole slidable on the support pin; the movable bracket of the wiper unit is biased between the elastic members; each of the elastic members of the wiper unit is mounted on the support pin and is received in the receiving chamber of the mounting seat; the movable bracket is moved relative to and deflected from the mounting seat of the blade when the wiper unit is driven by the support arm to reduce a frictional resistance applied on the wiper and the blade; and the elastic members provide a shock-absorbing function between the mounting seat of the blade and the movable bracket so as to eliminate vibration produced during movement of the wiper unit.
