Referring to fig. 1 and 2, further, the main movable ring 102 is mounted on the inner sleeve 101, and can freely rotate around the inner sleeve 101, but cannot move up and down along the inner sleeve 101; the auxiliary movable ring 104 is mounted on the outer sleeve 105, can freely rotate around the outer sleeve 105, but can not move up and down along the outer sleeve 105; the stop block 1021 on the main movable ring 102 is used to drive the main movable ring 102 to rotate when the outermost main umbrella rib 1061 of the umbrella rib plane opening and closing mechanism 10 is unfolded.

Referring to fig. 1 and 2, the forward and reverse rotation threaded rod 304 and the universal connector 303 may be mounted below the Z-shaped cross bar 307 or above the Z-shaped cross bar 307. When the forward and reverse rotation threaded rod 304 and the universal connector 303 are arranged below the Z-shaped cross rod 307, two closed plastic blocking pieces can be arranged below the Z-shaped cross rod to eliminate interference on the sun-shading cloth 50 when the forward and reverse rotation threaded rod 304 and the universal connector 303 rotate; when the forward and reverse rotation threaded rod 303 is installed above the Z-shaped cross bar 307, a moving space for left and right movement of the upper end portion of the umbrella rib opening and closing support rod 310 is reserved through notches formed in the Z-shaped cross bar 307 and the cover plate lifting elastic piece 603.

Referring to fig. 1 and 2, further, the rotating synchronized folding rod 107 can be freely folded in the vertical direction, and can ensure the synchronism of both ends when rotating in the horizontal direction, so that it can ensure the freedom of relative movement between the main movable ring 102 and the sub movable ring 104 in the vertical direction and the synchronism of rotation in the horizontal direction.

Referring to fig. 6, further, the inner sleeve 101 and the outer sleeve 105 of the two sets of rib plane opening and closing mechanisms 10 are fixed to the Z-shaped cross bar 307 and the lower cover 602 near to both ends, rather than at the center, so that enough storage space is reserved for the sunshade cloth 50 on the main rib 1061 of the two sets of rib plane opening and closing mechanisms 10 to ensure that the upper cover 601 and the lower cover 602 can completely store the sunshade cloth 50 in the covers and minimize the widths of the upper and lower covers (601, 602).

Referring to fig. 6 and 7, further, a plurality of main ribs 1061 of the sunshade have different lengths, and all of the main ribs 1061 and the sunshade cloth 50 together form a "square" sunshade area when the sunshade is unfolded.

Referring to fig. 1, preferably, the inner sleeve 102 is fixed to a Z-shaped cross bar 307 of the power transmission mechanism by a threaded structure; the outer sleeve 105 is fixed to the lower cover plate 602 by a screw structure.

Referring to fig. 1 and 2, preferably, the cover lifting resilient tab 603 is in an i-shaped structure, a middle portion of the cover lifting resilient tab is mounted on the Z-shaped cross bar 307, and two raised portions of two ends of the cover lifting resilient tab are respectively mounted in two resilient tab mounting grooves 6012 of the upper cover 601.

Referring to fig. 2 and 3, the Z-shaped cross bar 307 is preferably in a stretched "Z" shape. The stretching Z-shaped structure can ensure the normal operation of the universal connector 303 on one hand, and can ensure that the forward and reverse rotating threaded rods 304 are positioned on the outer tangent line straight line of the inner sides of the two main movable rings 102 on the other hand, thereby eliminating the occupation of the sunshade rib accommodating space when the rib opening and closing support rod 310 moves left and right, and further minimizing the width of the upper cover plate (601) and the lower cover plate (602).

Referring to fig. 8, further, the portable full automatic sunshade mounted on the roof of the automobile can be mounted on the top of the automobile by two sets of roof mounting rails 40.

The portable full-automatic sunshade mounted on the roof of the automobile has the following unfolding and folding processes:

with reference to fig. 1, 3, 4 and 5, the sunshade umbrella is unfolded: the wireless remote controller 204 sends an opening signal to the signal receiving controller 203, the signal receiving controller 203 controls the driving motor 202 to rotate forward according to the signal, the driving motor 202 rotates to drive the driving bevel gear II 302 to rotate through the driving bevel gear I301, and then the forward and reverse rotation threaded rod 304 is driven to rotate forward through the connecting rod and the universal connector 303, so that the two forward and reverse rotation nuts 305 are far away from each other along the forward and reverse rotation threaded rod 304. Two positive and negative rotation nuts 305 keep away from each other along positive and negative rotation threaded rod 304, on one hand, it drives the upper ends of two umbrella rib opening and closing support rods 310 to keep away from each other, and then makes two sets of umbrella rib plane opening and closing mechanisms 10 open in the vertical direction, thereby making the upper and lower cover plates (601, 602) and the main and auxiliary umbrella ribs (1061, 1062) of the sunshade open in the vertical direction, on the other hand, it drives umbrella rib opening and closing traction ring 306 to rotate through two umbrella rib opening and closing traction ropes 308, and then drives two outermost main umbrella ribs 1061 of the sunshade to expand according to the circular motion mode in the horizontal direction, finally drives the whole sunshade to expand in the horizontal direction, on the other hand, it makes two cover plate closing traction ropes 309 relax, and then makes the two ends of cover plate lifting elastic sheet 603 tilt up, and then makes the upper cover plate. The actions of the above three aspects finally make the sunshade forming sub-rib 1062 support the stable unfolding state of main rib 1061.

Referring to fig. 1, 3, 4 and 5, the sunshade umbrella is folded: the folding process of the sunshade is the reverse process of the unfolding process of the sunshade, and the folding process is not described here.

Referring to fig. 8, a is a top view of the sunshade fixed to the roof of an automobile in a folded state, in which the sunshade can be driven along with the automobile; the figure B is a top view of the invention fixed on the roof of the automobile in an unfolded state, and the sunshade can play a role in protecting the automobile and the like.

The present invention has been described in detail, and specific embodiments thereof have been shown and described herein, and it will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention.
