Vehicle-mounted solar shield

The utility model relates to a vehicle-mounted solar shield which is technically characterized in that the inverted Y-shaped pillar of the solar shield is arranged behind a vehicle seat; the top end of the inverted Y-shaped pillar is fixedly connected with an adjusting plate; the rear end of a central shaft is connected with a movable shaft on the rear side of the adjusting plate; the central shaft consists of an outer sleeve and an inner sleeve; the outer sleeve is sleeved outside the inner sleeve and can contract movably; and the solar shield consists of a front shield cloth shaft, a rear shield cloth shaft and shield cloth which are connected. Since the inverted Y-shaped pillar is arranged behind the vehicle seat, the vehicle-mounted solar shield not only can be effectively used for shielding sun, but also can not block the activity space and the sight line of a user to cause the driving to be more convenient and safe.
