Referring to fig. 3-4, a sectional hinged side roof panel 10 is shown with one end secured to a side armrest 30 and the other end secured to the vehicle body 20.

As shown in fig. 5 to 6, the side top plate 10 includes a fixing hinge 110, an upper side top plate 120, a stopper hinge 130, a lower side top plate 140, and a fixing lock 150; one end of the fixed hinge 110 is fixedly installed on the side armrest 30, the other end is rotatably connected with the upper side top plate 120, the upper side top plate 120 is connected with the lower side top plate 140 through the limit hinge 130, the end of the lower side top plate 150 is provided with the fixed lock 150, and the fixed lock 150 can rotate to open and close to connect the lower side top plate with the vehicle body 20.

Specifically, as shown in fig. 6, the position limiting hinge 130 in the present embodiment includes a first hinge plate 131, a first rotating shaft 132, and a first position limiting plate 133. The first hinge piece 131 has one end fixed to the lower side top plate 140 and the other end rotatably fixed to the first stopper piece 133 by the first rotating shaft 132, and is attached to the upper side top plate 120 together with the first stopper piece 133.

The first hinge plate 131 of the limiting hinge 130 preferably has an n-shaped structure, and the first limiting plate 133 preferably has a l-shaped structure, and the two are rotatable by the first rotating shaft 132 to realize a hinge rotation function between the upper side top plate 120 and the lower side top plate 140.

When the side top plate is in the opened state, the end of the upper side top plate 120 has a "Z" shaped bent part 121, and when the lower side top plate 140 rotates to the maximum 90 ° state, the first hinge piece 131 abuts against the upper surface of the "Z" shaped bent part 121 at the end of the upper side top plate to limit the opening angle.

When the side top plate is in a closed state, the end portion of the lower side top plate 140 has the "l" shaped bending piece 141, when the lower side top plate 140 rotates to the horizontal direction, the first hinge piece 131 abuts against the upper surface of the first limiting piece 133, and simultaneously, the "l" shaped bending piece 141 of the lower side top plate abuts against the lower surface of the "Z" shaped bending portion 121 of the upper side top plate, so that a limiting closing angle is provided.
