[0030] This embodiment provides a foldable blade mechanism for an electric vehicle. Please refer to Figures 1-4 as shown, which includes a rotating shaft 10, two hinge seats 20, two groups of curved rods 30, a plurality of flexible blades 40, and two groups of folding brackets 50; the two hinge seats 20 are respectively arranged near both ends of the rotating shaft 10; the two groups of curved rods 30 are respectively arranged on the two hinge seats 20. Among them, each group of curved rods 30 is multiple, and one ends of the multiple curved rods 30 are respectively hinged at intervals on the outer periphery of the hinge seat 20 and can rotate and fold inwardly close to the rotating shaft 10; both ends of each flexible blade 40 are respectively connected to the corresponding curved rods 30 in the two groups; both ends of the folding bracket 50 in each group are respectively arranged on the corresponding curved rod 30 in the group and the rotating shaft 10 inside the curved rod 30, and are used to support and unfold or link and fold the curved rod 30.

[0034] In this embodiment, spaced hinge interfaces 21 are provided on the outer periphery of the hinge seat 20, and one end of the curved rod 30 is hinged to the hinge interface 21.

[0035] Specifically, since the curved rod 30 can rotate and fold inwardly close to the rotating shaft 10, a limit blocking structure is provided on the outside of the hinge interface 21, and a rotating port is provided on the inside, so as to limit the outside of the unfolded curved rod 30, and at the same time, allow it to rotate and fold inwardly.

At the same time, a fixing structure for cooperation is provided between at least one group of the externally bracket 51 and the internally bracket 52.

At the same time, the fixing structure can adopt one or two groups and does not need to be set on all brackets.

[0046] This embodiment also provides a breeze power generation device for an electric vehicle, comprising a mounting frame, a power generation mechanism, a charging gun, and a foldable fan blade mechanism for an electric vehicle as described in any of the above items; the mounting frame is used to be installed on the roof of the electric vehicle; the fan blade mechanism is pivotally mounted on the mounting frame; the power generation mechanism is installed on the mounting frame, and is transmission-connected to the rotating shaft 10, and is connected to the charging port of the electric vehicle through the charging gun.

[0047] Specifically, the power generation mechanism includes at least a generator, and the generator can be directly connected to the rotating shaft 10 or indirectly connected through a transmission member; wherein, the power generation mechanism directly charges the electric vehicle charging port through a charging gun, which is convenient to plug and unplug and flexible to charge; in addition, the power generation device is generally unfolded for use when parking and can be folded and stored when driving to reduce driving resistance.

[0048] In this embodiment, the rotating shaft 10 of the fan mechanism is arranged parallel to the length direction of the electric vehicle.

[0049] Specifically, the roof of the electric vehicle has a larger installation length and area in the length direction, which is convenient for the installation and setting of the power generation device, and is also conducive to the multi-stage expansion of the fan blade mechanism in this direction.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
