Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

The utility model provides an automatic receive and release sunshade umbrella stand, refers to fig. 1 to fig. 3, include bracing piece 1, rib 2 and install first branch 3 and second branch 4 that are used for expandeing and contract rib 2 between bracing piece 1 and rib 2, first branch 3 with second branch 4 is articulated mutually, sliding connection has slider 11 on the bracing piece 1, it is articulated to keep away from 2 one end of rib 11 and second branch 4, regulation box 5 is installed to bracing piece 1 upper end, 5 internal rotations of regulation box are connected with reel 51, the winding has haulage rope 52 on reel 51, the free end and the slider 11 of haulage rope 52 are connected, install drive and location reel 51 pivoted drive division 6 in the regulation box 5.

When the sunshade umbrella is unfolded, a user starts the driving part 6 to drive the winding wheel 51 to wind up, so that the traction rope 52 drives the sliding block 11 to move upwards along the supporting rod 1, an included angle between the second supporting rod 4 hinged with the adjusting box 5 and the first supporting rod 3 is driven to be reduced, the umbrella ribs 2 are further unfolded, and the purpose of automatically unfolding the sunshade umbrella is achieved;

when this sun shade contracts, the user starts 6 drive winding wheel 51 unwrapping wires of drive division to under the action of gravity of rib 2, first branch 3 and second branch 4, slider 11 moves down along bracing piece 1, thereby drive and adjust the contained angle grow between box 5 articulated second branch 4 and the first branch 3, and then contract rib 2, reach the purpose of automatic shrink sun shade.

Specifically, the driving part 6 is a worm gear speed reduction motor. The worm gear and worm gear speed reducing motor has a self-locking function and can achieve the purpose of positioning the sunshade to keep opening. In the present embodiment, a control circuit board 53 and a storage battery 54 are further included, which are mounted inside the adjustment box 5, and the storage battery 54 and the driving portion 6 are electrically connected to the control circuit board 53, respectively.
