Since the number of teeth of the first driving gear 18 is less than the number of teeth 20 of the first driven gear, and the angle of rotation of the first driven gear is less than the angle of rotation of the first driving gear 18, the angle of rotation of the first grille blade 11 is less than the angle of rotation of the second grille blade 13; similarly, since the number of teeth of the second driven gear 21 is smaller than that of the second driving gear 19, the rotation angle of the second grid blade is smaller than that of the third grid blade 13.

According to another aspect of the present invention, there is also provided a vehicle, as shown in fig. 5-7, having a front portion provided with a grille opening provided therein with the grille arrangement 1 as described above.

In one embodiment, the vehicle is provided with a charging port 3 at an upper position of a front bumper 2, so that a grille opening is provided at a lower position of the front bumper 2, and a charging port cover is positioned at an upper portion of the front bumper to block an upper intake air of a radiator 4, as shown in fig. 6. Therefore, the utility model provides a grille shutter device 1 installs for each the upper end is to inboard pivoted angle when opening is along a plurality of for the closed condition grille shutter blade is from the top downward direction of arranging grow in proper order to through leading part air current upward flow through grille shutter device 1, thereby make the air current evenly flow to radiator 4. It will be understood by those skilled in the art that if the radiator 4 of the vehicle is disposed relatively downward compared to the position where the grille opening is disposed, the angle of the grille arrangement 1 in the open state needs to be set so as to be able to direct the air flow toward the lower position of the radiator.

Preferably, an air intake grille (not shown) is arranged in the grille opening, and the grille arrangement 1 is arranged on the inner side of the air intake grille. After the air outside the vehicle enters from the air inlet grille, the air is guided by the grille installation 1, as shown in fig. 7, the air flow is guided by the grille installation 1, part of the air flow blows to the lower position of the radiator 4, and part of the air flow is guided to the upper position of the radiator 4 by the grille vanes opened at different angles, so that the air flow uniformly flows through the radiator 4, and the air flow effectively dissipates the heat of the radiator 4 by the air suction effect of the cooling fan 5.

Preferably, the vehicle is provided with a control unit capable of controlling the opening or closing of the grille vanes in the grille arrangement in accordance with the operating conditions of the vehicle.

The control unit is configured to control the grille device to have 3 positions in total, a closed position, a half-open position, and a full-open position, according to the running state of the vehicle, for example, the opening and closing of the grille device is controlled in real time according to the vehicle speed, the coolant temperature, the air-conditioning state, and the like. For example, when the vehicle is started, the temperature of the coolant is low, and the required amount of outside air is small, and the opening area needs to be reduced. With the gradual rise of the temperature of the cooling liquid, the radiator needs a large air volume to meet the heat dissipation performance, and at the moment, the opening area needs to be increased. Therefore, through the utility model provides a vehicle idling temperature rise process can be accelerated to grid device 1, reduces car owner latency. And when the vehicle is driven at a high speed, the opening of the grille is adjusted, so that the starting resistance can be effectively reduced, the total resistance of the vehicle in driving is reduced, and the effects of reducing fuel consumption or improving the endurance mileage are achieved.

As shown in fig. 2, the grille blades are in a closed position, in which external wind cannot enter the interior of the nacelle through the grille.

In fig. 3, the grille blades are in the half-open position, and all three grille blades rotate in the clockwise direction, as indicated by the arrows in the figure, but the three blades rotate at different angles, the first grille blade 11 rotates at an angle of 20 ° compared with the closed position, the second grille blade 12 rotates at an angle of 30 °, and the third grille blade 13 rotates at an angle of 45 °.

As shown in fig. 4, the grille blades are fully opened, and the three grille blades continue to rotate clockwise on the basis of half opening, as shown by the arrows in the figure, the rotation angle of the first grille blade 11 is 40 ° compared with the closed state, the rotation angle of the second grille blade 12 is 60 °, and the rotation angle of the third grille blade 13 is 90 °.

Fig. 7 shows an air flow diagram when the grille shutter 1 is fully opened. When the grille blades are fully opened, air flows from the outside of the vehicle to the front of the radiator through the grille device 1 due to the influence of the vehicle speed or the rotation of the fan, and arrows in the figure indicate the direction of the wind. Because the opening angles of the three grille blades are different, the flowing direction of wind can be changed after the wind passes through the grille blades. Since the lower third grille blade 13 is parallel to the air intake direction, the air directly flows to the lower portion of the radiator 4 without changing the direction of the air after passing through the third grille blade 13. However, since the first grille blade 11 and the second grille blade 13 are at a certain angle to the direction of the incoming wind, when the airflow passes through the grille blades, the flowing direction is changed, specifically, the airflow is made to flow to the upper part of the radiator. Thus, although the grille opening of the vehicle is positioned at the lower part of the radiator, all the inlet air can uniformly pass through the radiator through the flow guiding effect of the grille blades.

Therefore, the grille device is adjusted according to the working condition of the vehicle, and the vehicle has the advantages of accelerating the idling temperature rise process of the vehicle, reducing the resistance of the vehicle and enhancing the heat dissipation performance of the vehicle.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
