Because the first rod piece sleeve joint hole and the second rod piece plug hole are provided with the acute angle, the stress is concentrated during use, and therefore the reinforced rib for connecting the outer side walls of the two holes is designed at the position.

Preferably, the included angle between the axis of the first rod piece sleeving hole and the axis of the second rod piece splicing hole is A, and the included angle is 60 degrees or more and is equal to or more than 10 degrees. The value of the angle determines the oblique extension angle of the second rod member by taking the first rod member as a reference, and further determines the angle range which can be covered by the two rod members supported by the rotatable double-rod joint.

Preferably, the left everting rod is outwards protruded to be arc-shaped; the chord of the arc is L, the distance from the highest point of the arc top to the chord is H, and the distance is 4 to or more than L/H to or more than 2.

The protruding degree is too little, lacks the practical use meaning, and protruding degree is too big can lead to driving unsafe, also can be higher to the material requirement of left side eversion pole.

Preferably, the front side wall of the front weather shield mounting groove is externally provided with a convex front end rod joint reinforcing rib, and the extending direction of the front end rod joint reinforcing rib is perpendicular to the length direction of the front weather shield mounting groove. The front side wall and the rear side wall of the front rain shield mounting groove are stressed positions, and the front side wall is positioned at the forefront end of the rod joint, so that the front rain shield mounting groove needs to be reinforced. And the rear side wall has other structures of the rod joint, and the strength is enough.

Preferably, a fastening bolt hole is also formed; the fastening bolt holes radially penetrate through two side walls of the longitudinal rod fixing holes. The fastening bolt hole is designed, and the upper end of the vertical rod can be fixed with the rod joint by using the fastening bolt after the vertical rod is inserted, so that the loosening is prevented.

Preferably, the fastening bolt hole also radially penetrates through a side wall of the cross bar fixing hole, which is close to one side of the longitudinal bar fixing hole. Therefore, the transverse rod can be fastened while the longitudinal rod is fastened, so that the transverse rod cannot slide left and right at will.

Preferably, the fastening bolt hole is provided with a pit at the position, and the outer side end of the fastening bolt hole is opened at the bottom of the pit. In order to avoid scratch caused by the fact that the head of the bolt stretches out of the groove, a pit can be designed at the corresponding position of the rod joint, and the fastened bolt head is arranged at the bottom of the pit.

Preferably, the front cross bar and/or the front side rail are hollow bars. The use of the mesoporous rod reduces the weight and the material consumption on the premise of ensuring the strength, and more importantly, the whole weight of the bracket can be reduced, and the influence of load on the driving of the vehicle is reduced.

In summary, the beneficial effects of the invention are as follows: the rain-proof awning bracket can be folded to a one-dimensional state, so that the occupied area is greatly reduced, and the storage and transportation are facilitated.
