The vehicle engine must be properly cooled when it is in a high temperature operating environment. The engine can work under the proper temperature, and the engine has good working performance and durability, and the vehicle can meet the requirement of exhaust emission.

The conventional electronic fan driven by a motor has small back pressure, is difficult to overcome large resistance and cannot meet the high heat dissipation requirement of a heavy vehicle. The radiator fan of a heavy vehicle is usually mounted on the engine crankshaft or an indirect connecting shaft, driven by the engine.

TABLE 1

Table 1 shows that provides an example engine coolant temperature threshold corresponding to reaching a fan angle and corresponding operating logic, such data can be obtained through experimentation by one skilled in the art and will not be described in detail herein.

Based on the same inventive concept, the present disclosure also provides fan blade rotational angle control methods, which are applied to the fan described above fig. 8 is a flowchart of the fan blade rotational angle control method provided by exemplary embodiment.

In step S11, the angle between fan blade 2 and fan blade disk 1 is detected.

In step S12, the temperature of the coolant of the vehicle is detected.

In step S13, the operation of drive mechanism 5 is controlled based on the detected angle and temperature to adjust the angle between fan blade 2 and fan blade disk 1.

The specific steps of the method have been described in the embodiments of the system, and are not described herein again.

In another embodiment, the step of controlling the operation of driving mechanism 6 according to the detected angle and temperature to adjust the angle between fan blade 2 and fan blade disk 1 (step S13) may include:

the operation of the drive mechanism 6 is controlled according to the detected angle and temperature to adjust the angle between the fan blade 2 and the fan blade disk 1 so that the angle between the fan blade 2 and the fan blade disk 1 increases with an increase in the detected temperature or with an increase in the temperature of the section in which the detected temperature is located.

Table 1 above shows an example in which the angle between fan blade 2 and fan blade disk 1 increases with an increase in the temperature of the section in which the detected temperature is present. For example, the motor 61 performs a rotation angle of 0.5 ° of the fan blade 2 per pulse signal. The temperature of the engine rises from 81 ℃ to 84 ℃, the rotation angle of the fan needs to rotate by 10 degrees, and the motor can be controlled to provide 20 times of pulse signals, and the rotation angle is 0.5 degree each time. After the motor executes 20 times of pulses, the angle sensor judges that the angle does not reach 10 degrees, and then the motor is controlled to provide pulse signals until the fan blade 2 reaches 10 degrees of rotation angle. Typically, the engine coolant temperature is around 80-85 deg.C, and the fan blades may be positioned at 10 deg. of rotation.

In a word, when the environment temperature is high and the whole vehicle is in a severe operating condition, the temperature of the engine coolant is continuously increased, the fan blades can be controlled to rotate by corresponding angles in sequence, the rotating angles of the fan blades are gradually opened, the air volume is increased, and the cooling performance is improved; when the ambient temperature is not high, and the vehicle operation operating mode is suitable, engine coolant temperature lasts the fall back, can control the corresponding angle of flabellum gyration, and the fan corner reduces gradually, and the amount of wind reduces, and the consumption reduces.

In yet another embodiment , the fan blade assembly further comprises a battery connected to the power generation section 5 for storing electrical energy, the drive shaft 8 is drivingly connected to an output shaft of an engine of the vehicle, the method may further comprise one or more of the following, based on FIG. 8:

when the engine of the vehicle is detected to be flamed out, controlling the work of the driving mechanism 6 to adjust the angle between the fan blade 2 and the fan blade disc 1 to a preset angle;

when the remaining capacity of the battery is detected to be less than the predetermined capacity, the operation of the driving mechanism 6 is controlled to adjust the angle between the fan blade 2 and the fan blade tray 1 to a predetermined angle.

Specifically, because there are various possibilities for the time interval from the engine off of the vehicle to the next ignition, if the time interval is long, the amount of electricity stored in the battery may not be sufficient to supply the motor 61 with work in time, therefore, when the engine off of the vehicle is detected, the angle between the fan blade 2 and the fan blade disc 1 can be adjusted to larger angles, so that the fan can have a larger heat dissipation capacity at the next ignition, thereby ensuring the safety of the vehicle in driving.

At this time, the angle between the fan blades 2 and the fan blade tray 1 may be adjusted to larger angles, so that even if the battery interrupts the power supply, the power generation part 5 cannot generate enough power in time, the fan can be ensured to have a large heat dissipation capacity, thereby ensuring the safety of the vehicle in driving.

Based on the same inventive concept, the present disclosure also provides vehicles including the fan blade rotation angle control system described above, wherein the drive shaft 8 is drivingly connected to an output shaft of an engine of the vehicle.

The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

In addition, any combination of various embodiments of the present disclosure may be made, and the same should be considered as the disclosure of the present disclosure, as long as it does not depart from the spirit of the present disclosure.
