It should be pointed out that ordinary technical people in this field can make variations and improvements under the prerequisite of not alienating themselves from the conception of this invention. These belong to the protection scope for this invention.

As shown in FIG. 1 and FIG. 2, the multifunctional sunshade as provided by this invention comprises a housing 1, a raising and lowering mechanism 2, a folding mechanism 3, a solar panel 4, a base 5 and a sunshade cloth. 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.

As shown in FIG. 8, when the multifunctional sunshade operates normally, the raising and lowering tray 221 connects with the drive nut 213 via the emergency release connecting part 222, as a result, the raising and lowering tray 221 can move up or down accordingly being driven by the nut 213. And if the multifunctional sunshade has a failure leading to the screw 211 stopping rotation, the sunshade cloth can not draw in if the raising and lowering tray 221 continues to maintain a connection with the drive nut 213. So the emergency bolt 2222 can be removed from the drive nut 213 to have the raising and lowering tray 221 and the drive nut 213 separate with each other, as shown in FIG. 4, as a result, under an manual force, the raising and lowering tray 221 can still be raised to draw in the sunshade cloth. Optimally, the emergency bolt 2222 is an inside hex bolt.
