More specifically, the raising and lowering mechanism 2 connects to the housing 1, the raising and lowering mechanism 2 drives the folding mechanism 3 to spread and draw in, the housing 1 comprises a housing body 11 and a motor 12, the raising and lowering mechanism 2 includes: a raising and lowering rod 21, a raising and lowering platform 22 and a raising and a lowering seat 23, in which: the motor 12 set up in the housing body 11 drives the raising and lowering platform 22 to move along an axial direction of the raising and lowering rod 21, the raising and lowering rod 21 is installed in the housing body 11 via the raising and lowering seat 23, the sunshade cloth connects to a top of the folding mechanism 3, the solar panel 4 is installed at a top of the raising and lowering mechanism 2 and the housing 1 is installed at the base 5 in a removable manner.
In this embodiment example, the raising and lowering platform 22 is located above the raising and lowering seat 23, when the raising and lowering platform 22 moves from bottom to top, the raising and lowering platform 22 drives the folding mechanism 3 to draw in gradually, when the raising and lowering platform 22 moves from bottom to top, the folding mechanism 3 spreads gradually being driven by the raising and lowering platform 22, accordingly, the sunshade cloth connecting to the folding mechanism 3 also draws in and spreads with it. In a variation example, the raising and lowering platform 22 can be located under the raising and lowering seat 23, the folding mechanism 3 can draw in and spread similarly being driven by the raising and lowering platform 22.
