[0027] In this embodiment, the electric vehicle canopy is fixedly installed on the roof of the vehicle during use and can be connected and fixed to the roof rack. When not in use, such as... Figure 2 As shown, in its retracted state, the first and second baffles (12, 22) are retracted into the area where the first and second base plates (11, 21) are located, and are situated on the roof of the vehicle. Their edges do not extend beyond the window glass, thus not obstructing the view of passengers and the driver.

[0036] The third baffle 31 is provided with a circular arc profile at the opposite corner away from the first baffle 12 and the second baffle 22, which can not only improve the aesthetic appearance but also improve the safety, and can reduce the damage to pedestrians or other vehicles when colliding.
