Description
Technical field
The utility model belongs to parasols technical field, is related to a kind of solar sunshade.
Background technology
Parasols is also parasol, is primarily used for hiding the parachute kit of anti-direct irradiation of sunlight.In general parasols includes
Base and the vertical rod being arranged on base and foldable and umbrella cloth that is being deployed in vertical rod.Parasols can keep away sunlight due to it
Kept off the rain with windproof, be the utensil that people often use out of doors.In picnic, open air spend a holiday, security and people pass through during the rest of park
Lucifuge rain cover is carried out usually through parasols.
Parasols only has single function at present, but people often use mobile device for a long time under parasols, from
And make mobile device electricity quickly without and out of doors and bad charging, cause certain trouble and inconvenience.
Application No. CN201210319048.X umbrella using solar energy is disclosed for this Chinese patent literature, it include umbrella cover and
Umbrella stem, umbrella cover are provided with solar panel, and the bottom plate of umbrella stem is provided with battery, and battery is connected with solar panel, umbrella
Outlet and USB interface are additionally provided with bar, outlet and USB interface are connected with battery respectively.The umbrella using solar energy can
Solar energy is collected in people's sunshade by solar panel and is converted into electric energy to accumulators store, sets USB interface can
Obtained for mobile device or other electrical equipment grafting electric.Although umbrella using solar energy disclosed in the patent disclosure satisfy that people fill under parasols
The requirement of electricity, but solar panel is arranged on umbrella cover, solar panel is rigid so that parasols is difficult to fold
Deposit and transport afterwards, do to meet the stored collapsed of parasols by solar panel small, be difficult to the need for meeting power supply again
Ask.And solar panel is fixed on the immovable steering of umbrella cover, so as to be difficult to be directed at the sun so that collect the effect of solar energy
Rate is not high.
The content of the invention
There is above mentioned problem in the utility model, it is proposed that a kind of solar sunshade, this practicality are new for existing technology
Type technical problem to be solved is how to make to have the parasols of solar panel to be easy to storage to transport.
