Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] To make the above objects, features, and advantages of the present invention more clearly understandable, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0033] As Figures 1 - 4 shown, the embodiments of the present invention provide an automotive intake grille kinetic energy recovery device, including:

[0034] A grille main body 1, in a double-arc airfoil shape, rotatably arranged at the automotive air intake;

[0035] A generator 2, whose rotor is connected to the grille main body 1. The grille main body 1 is connected to the outer shell of the generator 2 through a connecting bearing 3. When the vehicle decelerates, the kinetic energy of the air flow at the air intake drives the grille main body 1 to rotate and drives the rotor of the generator 2 to rotate relative to the stator to generate electricity. The output end of the generator 2 is electrically connected to the power storage unit 9 and the automotive battery 10 through a connecting wire.

[0036] In this embodiment, the connecting bearing 3 is arranged at the top of the grille main body 1, and the bottom of the grille main body 1 is rotatably arranged at the automobile air inlet through the mounting bearing 4.

[0037] In this embodiment, there are four groups of the grille main body 1 and the generator 2 arranged in one-to-one correspondence, and adjacent grille main bodies 1 are arranged at intervals, and multiple generators 2 are connected in parallel.

[0038] In this embodiment, it further includes: a base 5, and multiple grille main bodies 1 are uniformly arranged at intervals along the length direction of the base 5. The bottom of the grille main body 1 is rotatably arranged on the base 5 through the mounting bearing 4, and the base 5 is arranged at the automobile air inlet; a power storage unit 9 and an automobile battery 10 are arranged on the base 5.

[0039] In this embodiment, it further includes:

[0040] A first partition 6, which is vertically arranged on the base 5, and the power storage unit 9 and the automobile battery 10 are arranged on the first partition 6;

[0041] A second partition 7, which is arranged on one side of the base 5, and the first partition 6 is arranged on the other side of the base 5;

[0042] A third partition 8, the upper surfaces of the first partition 6 and the second partition 7 are flush, and both ends of the third partition 8 are respectively arranged on the upper surfaces of the first partition 6 and the second partition 7, and the generator 2 is embedded in the third partition 8. The first partition 6, the second partition 7, the third partition 8 and the base 5 form an intake grille frame, which can be integrally installed at the automobile air inlet.

[0043] In this embodiment, the size of the grille main body 1 is: length 60mm, width 30mm, height 100mm; the first partition 6 and the second partition 7 have the same size, and the size of the first partition 6 is: length 100mm, height 114mm, thickness 7mm; the size of the third partition 8 is length 300mm, width 100mm, thickness 6mm.

[0044] In some other embodiments, it further includes:

[0045] A locking unit, which is arranged on the base 5 for locking the grille main body 1, and the locking unit can adopt a micro motor to realize the start and stop of the rotation of the grille main body 1;

[0046] A controller, which is electrically connected to the power storage unit 9 and the automobile battery 10. When the power of the power storage unit 9 and the automobile battery 10 reaches the preset range, the controller locks the grille main body 1 through the locking unit. The locking unit can be any suitable electrically controlled locking part, and it can limit the rotation of the grille main body 1 when receiving the instruction sent by the controller.

[0047] The specific working process is as follows:

[0048] When the vehicle decelerates, the kinetic energy of the airflow at the vehicle air inlet rapidly increases within a short period of time. Since the grille body 1 is in a double-arc airfoil shape and the airflow at the vehicle air inlet is turbulent, the grille body 1 cannot maintain a balanced state, will rotate due to imbalance and keep rotating by inertia. The grille body 1 drives the rotor of the generator 2 to rotate relative to the stator, and multiple generators generate electricity synchronously. The generated electric energy is transmitted to the power storage unit 9 and the vehicle battery 10 through connecting wires, and the power is preferentially supplied to the vehicle battery 10.

[0049] When the power of the vehicle battery 10 reaches the preset range, the power is transmitted to the power storage unit 9.

[0050] When the powers of both the vehicle battery 10 and the power storage unit 9 reach the preset range, the controller locks the grille body 1 through the locking unit, and the generator 2 stops generating electricity.

[0051] It should be noted that there is sufficient clearance between adjacent grille bodies 1. When the grille body 1 is locked, even if the grille body 1 is perpendicular to the air inlet direction, sufficient air can still enter through this clearance.

[0052] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0053] The embodiments described above are only for describing the preferred mode of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
