The utility model discloses a sunshade screen before truck as shown in figure 1, the sunshade screen includes that end seat shell assembly 1, curtain cloth pull rod assembly 2, a left side retrieve rocking arm assembly 3 and the right side retrieve rocking arm assembly 4.

As shown in the attached drawing 2, the end seat shell assembly fixes the left end seat assembly 1.3 and the right end seat assembly 1.4 at two ends of the aluminum profile shell 1.1 respectively in a self-tapping mode, the rib winding drum 1.2 is fixed with the right end seat assembly 1.4 through the end seat positioning column 1.5, and the left end of the rib winding drum 1.2 is fixed with the left end seat assembly 1.3 through internal tooth meshing. The rib winding drum is internally provided with a coil spring, the winding of the coil spring is realized through the rotation of the rib winding drum, and the winding storage energy of the coil spring is used as the power for recovering the curtain cloth pull rod assembly.

As shown in fig. 3, the left end seat assembly 1.3 includes a side fixing plate 1.3.1, a half roller cover 1.3.2, a mandrel 1.3.3, a ball 1.3.4 and a static lock roller 1.3.5, the mandrel 1.3.3 is connected to the left end of the static lock roller 1.3.5, a protrusion with a groove is arranged outside the mandrel, the left end of the mandrel is fixed in a rod hole of the side fixing plate 1.3.1 through square shape matching, and the side fixing plate is connected with a vehicle body. The middle of the half roller cover 1.3.2 is provided with a shaft hole, and the shaft hole is matched with the mandrel 1.3.3. The 1.3.4 ball rolls in the mandrel 1.3.3, the static lock roller 1.3.5 and the half roller cover 1.3.2, so that the locking and the separation of the 1.3.5 static lock roller and the 1.3.3 mandrel are realized.

As shown in fig. 3, the left end seat assembly 1.3, the static lock roller 1.3.5 is matched with the hole shaft of the 1.3.3 core shaft, the half roller cover 1.3.2 is matched with the hole shaft of the 1.3.3 core shaft, and the ball 1.3.4 rolls in the core shaft 1.3.3, the static lock roller 1.3.5 and the half roller cover 1.3.2 to realize the locking and separation of the static lock roller 1.3.5 and the core shaft 1.3.3. As shown in fig. 4, the static lock roller rotates counterclockwise about 1.3.5 to drive the balls 1.3.4 to roll out of the grooves of the mandrel, and the static lock roller 1.3.5 and the mandrel 1.3.3 realize relative rotation. The static lock roller rotates clockwise, the ball sinks in the mandrel groove, the ball limits the static lock roller to rotate, and the static lock roller and the mandrel realize relative locking.

As shown in the attached figure 5, the cord fabric 2.1 is clamped and fixed on the F-shaped pull rod 2.2 through the clamping groove, and the left choke plug 2.3 and the right choke plug 2.4 block two sides of the F-shaped pull rod after the cord fabric is clamped into the F-shaped pull rod.
