Description

Technical Field

[0001] The invention belongs to the technical field of vehicle blinds, and in particular relates to a vehicle photovoltaic blind. Background Art

[0002] Compared with curtains, blinds have flexible blades that curtains lack. In terms of sunshade, blinds can not only block ultraviolet radiation, but also adjust indoor light.

[0003] Medium-sized and large buses are equipped with windows, but they do not have a sunshade function. Therefore, some buses have sunshade cloths installed inside the bus to completely cover the windows; some buses have blinds installed inside the bus to provide sunshade through leaf windows. However, current vehicle blinds have the following problems: (1) When the blinds are not needed, they cannot be hidden, which affects the appearance; (2) When the blinds need to be closed, all the leaves can only be controlled to open and close at the same time. If passengers want to see things outside the window, they need to open all the leaves at the same time. However, after opening, they cannot provide a good sunshade effect. At the same time, due to the large area of ​​light transmission, they do not provide privacy effect; (3) The blinds use the power supply inside the vehicle, which consumes the vehicle's power.
