DETAILED DESCRIPTION OF THE INVENTION

As shown in FIG. 1 and FIG. 2, a foldable chair with an awning bracket comprises a foldable chair 1 and a foldable awning 2, which can achieve linkage folding. The foldable awning 2 comprises a soft awning 21 and an awning bracket 22. The said awning bracket 22 has a corresponding foldable bracket 3 on either side, which comprises a supporting rod 31, a cross rod 32, a fixed seat 33, a connecting piece 34 and a foldable assembly 35. The supporting rod 31 is movably hinged on a fixed seat 33 with a rivet 4, is fixed on the upper end of the backrest rod 11 of the foldable chair with the help of the fixed seat 33, forms the linkage between the awning bracket 33 and the foldable chair 1, and composes a foldable assembly; the cross rod is used to unfold the soft awning 21.
According to FIGS. 2-5, a lower end of the supporting rod 31 in the awning bracket 22 is fixed on the upper end of the backrest rod 11 with the help of the fixed seat 33. The fixed seat 33 is provided with a blocking component 331 limiting the forward swing of the supporting rod 31, which is kept vertically with the help of the blocking component 331, and the remaining is the folding component provided for free backward swing of the supporting rod 31. The upper end of the supporting rod 31 is fixed with a connecting piece 34, on top of which, a circular arc groove 341 is provided. The cross rod 32 is movably hinged on the connecting piece 34 with a rivet 4, and the folded cross rod 32 can be supported by local setup in the said circular arc groove 341, so as to maintain the angle of the folded cross rod 32.
As shown in FIG. 3 and FIG. 5, a direction guide piece 36 is fixed on the hinge component of the supporting rod 31 and fixed seat 33, and the thickness of the direction guide piece 36 is equivalent to the diameter of the supporting rod 31. The rivet 4 successively passes through the fixed seat 33 and direction guide piece 36, and forms the movable hinge structure. Furthermore, the rivet 4 passes through the center of the direction guide piece 36, on the edge of which, the supporting rod 31 is fixed, so that the supporting rod 31 has an offset when it is unfolded or folded in place, so as to satisfy the requirement of moving the awning bracket 22 to the back of the backrest rod 11 of the foldable chair when the awning is folded or not used.
As shown in FIG. 3 and FIG. 4, a direction guide piece 36 is also fixed on the hinge component of the cross rod 32 and connecting piece 34, and thickness of the direction guide piece 36 is equivalent to the diameter of the cross rod 32; the rivet 4 successively passes through the conducting piece 34 and direction guide piece 36, and forms the movable hinge structure. Furthermore, the rivet 4 passes through the center of the direction guide piece 36, on the edge of which, the cross rod 32 is fixed.
As shown in FIG. 2 and FIG. 6, a foldable assembly 35 is connected between the foldable brackets 3 on both sides is composed of two long rigid pieces 351, one end of which is movably hinged with a rivet, and at the end of this hinge point 352, one side edge of at least one long rigid piece is bent to limit the excessively unfolded edgefold 353 of another long rigid piece 351; the other end of both long rigid pieces 351 is respectively movably hinged on the vertical surface 342 of the connecting piece 34 through a rivet, and forms an linkage structure between the foldable brackets 3 on both sides. In the unfolding process, the connecting piece 34 gradually travels to the highest point with the supporting rod 31, and its vertical surface 342 faces forward, as shown in FIG. 2. Both long rigid pieces 351 are naturally unfolded under their own gravity, and are hung down. Here, the edgefold 353 can present the long rigid pieces 351 from being excessively unfolded, and can stably support the foldable brackets 3 on both sides and improve their wind resistance. During the folding process, it is only necessary to turn the supporting rod 31 or cross rod 32 towards the back of the backrest 11. When the supporting rod 31 is hung upside down, the connecting piece 34 is also hung upside down accordingly, as shown in FIG. 6. Both long rigid pieces 351 are also naturally hung down under their own gravity, and the edgefold 353 under this angle loses the effect of limiting another long rigid piece 351. Both cross rods 32 are automatically turned and hung down behind the backrest rod 11. Here, the foldable chair 1 relieves the awning effect of the foldable awning 2. When the foldable chair 1 is folded again, both backrest rods 11 are gathered together under an external force, driving the supporting rod 31 and connecting piece 34 to be gathered together. Here, the edgefold 353 loses the effect of limiting the long rigid pieces 351, which can be flexibly folded accordingly under their own weight.
In the above unfolding and folding process, it is only necessary to operate the foldable awning 2 on one side due to the linkage effect of the foldable assembly 35 and the effect of the direction guide piece 36, which can maintain the angle consistency of the foldable brackets 3 on both sides in the unfolding and folding process to the maximum extent. That is, if the backrest rod 11 is regarded as fixed, then the angle of both fixed seats 33 is consistent, so that the direction guide pieces 36 fixed on both supporting rods 31 can still keep consistent direction even if they are not synchronous in the unfolding or folding process, and will not be blocked due to torsion, thereby allowing for smoother operation. Likewise, the direction guide pieces 36 fixed on the cross rods 32 have the same effect.
According to FIG. 6, the folded awning bracket 22 is gathered on the back of the backrest rod 11, occupies a little space, and is harmonious with the whole foldable chair.
According to FIG. 7, the foldable assembly 35 may also be arranged between both cross rods 32, and is also composed of two long rigid pieces 351, one end of which is movably hinged with a rivet, and at the end of this hinge point 352, one side edge of at least one long rigid piece 351 is bent to limit the excessively unfolded edgefold 353 of another long rigid piece 351; the other end of both long rigid pieces 351 is respectively movably hinged on the cross rods 32 through a rivet, forms the linkage structure between the foldable brackets 3 on both sides and can maintain the rigidity and strength of both cross rods 32.
