The support unit 140 includes a support sleeve 141, and the support sleeve 141 is covered outside the first transmission rod 111, so that not only can the first transmission rod 111 be protected, but also the second half gear 1321, the first support rod 132, the rotation bearing 112, the blades 122, and the generator 121 can be effectively supported. The power generation unit 120 includes a generator 121 and blades 122, wherein the generator 121 is internally provided with a stator and externally provided with a rotor. The stator is sleeved on the middle part outside the supporting sleeve 141, and the inner wall is fixedly connected with the outer wall of the supporting sleeve 141. The rotor ring is arranged on the outer side of the stator, and a plurality of fixing seats are uniformly arranged on one end face along the circumferential direction. The generator 121 as a whole does not move with the first transmission rod 111. The plurality of blades 122 are uniformly distributed along the circumferential direction of the rotor. The root of each blade 122 is rotatably connected to the rotor and the first transmission rod 111, respectively. Specifically, the plane of each blade 122 is inclined with respect to the axis of the first transmission rod 111, and a blade mount is fixed to the root.

In addition, the electric vehicle wind power generation device can also be installed on an armored vehicle to generate power for communication equipment on the armored vehicle, and can also be installed in a power station. When the electric vehicle wind power generation device is installed on the electric vehicle, the electric vehicle wind power generation device is electrically connected with a vehicle-mounted power supply through a cable. The roots of the plurality of blades 122 uniformly distributed along the circumferential direction of the rotor are driven by the same first driving rod 111, so that the tips of the plurality of blades 122 are close to each other or the tips of the plurality of blades 122 are far away from each other. During this process, the generator 121 does not move with the first transmission rod 111. When the tips of the blades 122 are far away from each other and spread, the blades 122 rotate under the driving of wind force to drive the rotor to rotate around the axis of the first transmission rod 111, and in this process, the position of the stator relative to the first transmission rod 111 remains unchanged all the time and does not rotate, and the rotor rotates relative to the stator to generate electricity.

When the electric vehicle runs, the electric vehicle wind power generation device is in a folded state (as shown in fig. 8), and the occupied space is greatly reduced. Therefore, the resistance suffered by the electric vehicle with the power generation device is basically kept unchanged when the electric vehicle runs, the power generation device in the folded state basically does not influence the cruising ability of the electric vehicle, and the stressed area is greatly reduced because the power generation device is in the folded state, so that the possibility that the electric vehicle wind power generation device is impacted by foreign objects is reduced, the electric vehicle wind power generation device is not easy to generate a frame, and the service life of the electric vehicle wind power generation device is prolonged.

In some of these applications, the position sensor 1422 is a photoelectric sensor, the receiver of which is fixed to the bottom inside the support base 142, and the transmitter is fixed to the bottom surface of the turntable 1421. Before the blades 122 of the power generation unit 120 are folded, the controller controls the operation of the cylinder to connect the side wall of the inner swivel with the side wall of the outer swivel. Then, the controller controls the driving motor 161 to operate, so as to rotate the turntable 1421 of the supporting seat 142 and drive the emitter to rotate around the axis of the turntable 1421. When the transmitter and the receiver are vertically aligned, the controller controls the driving motor 161 to stop operating. Then, the controller controls the electric push rod 154 to operate so as to lower the height of the power generation unit 120 and to retract the tail 130 and the power generation unit 120.
The unfolding process of the wind power generation device of the electric vehicle is as follows: the length of the electric push rod 154 extending out of the cylinder is gradually increased, the second support rod 152 and the third support rod 153 are rotated leftwards, and the axes of the second support rod 152 and the third support rod 153 are gradually moved to the vertical line. In this process, the third supporting rod 153 drives the third driving rod 117 to rotate, and further drives the second driving seat 116, the second driving rod 115 and the first driving seat 114 to move upwards, so as to drive the first driving rod 111 to move leftwards. The first driving rod 111 moving leftwards drives the rotating bearing 112 and the second driving shaft sleeve 113 to move leftwards, and further drives the first half gear 1221 to rotate clockwise, and simultaneously drives the second half gear 1321 to rotate anticlockwise, so that the tips of the plurality of blades 122 are far away from each other to be unfolded, and the guide vane 131 is unfolded.
The preparation process before the electric vehicle wind power generation device generates electricity is as follows: the side wall of the inner swivel is disconnected with the side wall of the outer swivel, the tail 130 drives the turntable 1421 to rotate through the supporting sleeve 141, and drives the first transmission seat 114 and the second transmission rod 115 to rotate through the first transmission rod 111. After passively adjusting the azimuth of the power generation unit 120 according to the wind direction, the plurality of blades 122 are driven to rotate by wind force, and drive the rotor to rotate relative to the stator.
The preparation process before the wind power generation device of the electric vehicle is folded is as follows: the side wall of the inner swivel is connected with the side wall of the outer swivel, and the driving motor 161 drives the transmission gear 162 to rotate so as to drive the outer swivel to rotate, thereby driving the inner swivel, the turntable 1421, the air guide sleeve 143, the supporting sleeve 141 and the power generation unit 120 to rotate, so that the power generation unit 120 returns to the initial unfolding position.
The folding process of the wind power generation device of the electric vehicle is as follows: the length of the electric push rod 154 extending out of the cylinder is gradually reduced, the second support rod 152 and the third support rod 153 are rotated rightward, and the axes of the second support rod 152 and the third support rod 153 are gradually moved to the horizontal. In this process, the third supporting rod 153 drives the third driving rod 117 to rotate, and further drives the second driving seat 116, the second driving rod 115 and the first driving seat 114 to move downward, so as to drive the first driving rod 111 to move rightward. The first driving rod 111 moving rightward drives the rotating bearing 112 and the second driving shaft sleeve 113 to move rightward, thereby driving the first half gear 1221 to rotate counterclockwise, and simultaneously, driving the second half gear 1321 to rotate clockwise, so that the tips of the plurality of blades 122 are close to each other, and the guide vane 131 is folded.
