However, in the prior art, the motor for driving the cooling fan is limited by the working principle and is difficult to miniaturize, in order to meet the installation requirement of the motor, only the size of the fan blades is reduced, so that the motor occupies an excessive airflow area, the air discharge quantity of the cooling fan is limited, and the output power, noise reduction and heat dissipation effects are affected.
In the field of power propulsion, with the improvement of requirements of micro aircrafts on high maneuvering and long endurance performance, the power density and the energy conversion efficiency of a micro power device need to be improved. The existing micro-aircraft power device drives the propeller to rotate by using the traditional micro-motor, when the load of the propeller is increased, the interior of the micro-motor generates a large amount of heat due to the large increase of current, so that the energy conversion efficiency is greatly reduced, the power density cannot be improved, and even overheat burnout occurs.

Further, the surface of the fan blade is a three-dimensional aerodynamic curved surface.
Further, the positive electrode and the negative electrode are both in a convex tip shape.
A miniature electrostatic fan comprises the electrostatic drive-based fan blade.

The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
The electrostatic driving principle is driven by utilizing electrostatic force, which is a rotating driving principle of a micro-electromechanical system that is practical earlier, the electrostatic force is attraction force and repulsive force between two charged bodies in the electrostatic field caused by carrying same or different charges, and the research of the micro-mechanical system has proved that: the conductor rotor can actively rotate at a high speed in the electrostatic field, the rotating speed can be up to tens of thousands of revolutions per minute, no additional motor drive is needed, moreover, the electrostatic force is directly proportional to the secondary discharge of the linear dimension of the structure, and when the structure dimension is reduced, the electrostatic force is increased relative to the structure volume. Therefore, driving the micro-sized fan blades using electrostatic force is an important method for implementing the micro-sized heat dissipation fan and the micro-power device.
Example 1:
Referring to fig. 1, a fan blade 4 based on electrostatic driving is arranged on a rotating shaft, a housing 1 is arranged around the fan blade, the housing 1 is preferably in a circular shape, and a plurality of positive electrodes 2 and negative electrodes 3 are arranged on the inner surface of the housing 1 at intervals. Preferably, the preparation materials of the positive electrode 2 and the negative electrode 3 are metal coatings, and the processing method is a spraying method; the material insulating material of the shell 1 is preferably light plastic, and the processing method is 3D printing or injection molding.
Referring to fig. 2, the fan blade 4 uses an insulating material as a matrix, and a conductive coating is covered on the blade tips of the fan blade 4 near the positive electrode 2 and the negative electrode 3, preferably, the fan blade 4 is made of carbon fiber by a processing method of thermoplastic molding. According to the principle of electrostatic driving, electrostatic force is generated to drive the fan blades 4 to rotate by applying voltage to the positive electrode 2 and the negative electrode 3, the surfaces of the fan blades 4 are three-dimensional pneumatic curved surfaces, and the fan blades 4 are driven by the electrostatic force and do not influence the pneumatic efficiency.
The radial distance between the positive electrode 2, the negative electrode 3 and the fan blade 4 (the distance along the linear direction of the radius of the annular shell 1) is less than or equal to one fifth of the radial length of the fan blade.
Furthermore, the positive electrode 2 and the negative electrode 3 are both in raised tip shapes, and the raised directions of the positive electrode and the negative electrode are obliquely arranged towards the rotating direction of the fan blade 4, so that the fan blade rotates along a specific direction.
Furthermore, the input power sources of the positive electrode 2 and the negative electrode 3 are high-voltage direct current, and the working voltage and the working current are relatively high, so that the energy consumption is low, and the capability conversion rate is relatively high. In addition, since the electrostatic driving fan needs to be mutually insulated between the blades 4, the larger the area of the conductive coating of the blade tip is, the larger the electrostatic force applied to the blades 4 is, but the too large area of the conductive coating can cause too small safety distance between the blades 4, and breakdown short circuit can occur under high voltage, so the area of the conductive coating is determined by the maximum working voltage of the positive electrode 2 and the negative electrode 3.
Referring to fig. 3, the principle of electrostatic driving of the fan blade is as follows:
After the positive electrode 2 and the negative electrode 3 are respectively applied with high-voltage direct current, the positive electrode 2 has positive charges, the negative electrode 3 has negative charges, and stable electrostatic fields are formed between the positive electrode 2, the negative electrode 3 and the fan blades 4;
(2) When the gap between the fan blade 4 and the positive electrode 2 is extremely small, part of positive charges carried by the positive electrode 2 jump to the blade tip of the fan blade 4 to enable the fan blade 4 to have positive charges, and according to the principle of repulsion of the same charges, the fan blade 4 is rotated by repulsive force of the positive electrode 2, and the rotating direction is the direction (clockwise) of the protrusion of the blade tip;
(3) When the fan blade 4 approaches to the negative electrode 3, according to the principle of heterogeneous charge phase attraction, negative charges carried by the negative electrode 3 generate attraction to the fan blade 4 with positive charges, and the fan blade 4 is driven to continuously rotate clockwise;
(4) When the gap between the fan blade 4 and the negative electrode 2 is extremely small, part of negative charges carried by the negative electrode 3 jumps to the blade tip of the fan blade 4, so that positive charges carried by the fan blade 4 are neutralized and negatively charged, and the fan blade 4 is subjected to repulsive force of the negative electrode to continue to rotate clockwise.
(5) Since the positive electrode 2 and the negative electrode 3 are arranged at intervals, the blades 4 are subjected to repulsive force and attractive force in accordance with the rotation direction at intervals, and thus the blades 4 can be kept continuously rotated.
Further, by adjusting the number of the positive electrodes 2,3, the output power of the fan driven based on the electrostatic principle can be changed. For example, increasing the number of positive and negative electrodes can create a greater electrostatic force, thereby increasing the output power of the fan driven based on the electrostatic principle.
The positive electrode 2 and the negative electrode 3 of the housing 1 are in the same plane with the fan blade 4, and when the positive electrode 2 and the negative electrode 3 are arranged at the top end of the fan blade 4, the direction of the electrostatic force generated at the moment can maximally push the fan blade 4 to rotate. The positive electrode 2 and the negative electrode 3 of the casing 1 can be located on the side surfaces (not shown in the figure) of the fan blades, and electrostatic force can be generated to drive the fan blades to rotate.
Example 2:
a miniature electrostatic fan is used for cooling miniature electronic equipment and comprises the fan blade based on electrostatic driving. Preferably, the diameter of the whole micro fan is 23.5mm, the length of the fan blade 4 is 10mm, the thickness of the whole micro fan is 3mm, the thickness of the tip conductive coating of the fan blade 4 is 37 nanometers, and the minimum radial distance between the positive electrode 2 and the negative electrode 3 and the fan blade 4 is 0.5mm. Compared with the traditional motor-driven fan, the miniature electrostatic fan has smaller thickness, larger fan blades and smaller noise, and can meet the application environment of the miniature cooling fan with small size and planarization.
Example 3:
As shown in fig. 4-5, a fan blade with hybrid driving includes the fan blade 4 based on electrostatic driving described in embodiment 1, and further includes a micro motor 5, where the housing 1 of the fan blade is an airflow duct, preferably, the duct is a circular ring, and the circular ring has a circular ring effect, so that the power device has low noise, good use safety, and high aerodynamic efficiency. Preferably, the duct is made of lightweight plastic and is manufactured by 3D printing or injection molding. The miniature motor is preferably a miniature electromagnetic motor.
Preferably, the diameter of the fan blade of the hybrid drive is 30mm, the diameter of the duct is 35mm, the diameter of the miniature electromagnetic motor 5 is 4mm, the length is 8mm, the thickness of the tip conductive coating of the fan blade 4 is 37nm, the minimum radial clearance between the positive electrode and the negative electrode and the fan blade 4 is 0.5mm, and the total mass is 600mg.
A mixed driving method of fan blades comprises the following steps:
(1) Mounting electrostatic drive-based fan blades on an output shaft of the motor;
(2) The battery is connected with the boost circuit to form a power supply module, and the power supply module can directly output low-voltage direct current by the battery or output high-voltage direct current by the boost circuit;
(3) Introducing the low-voltage direct current into the positive electrode and the negative electrode of the motor, and simultaneously introducing the high-voltage direct current into the positive electrode and the negative electrode of the fan blade;
(4) The power supply module adjusts the working states of the motor and the fan blades by controlling high-voltage direct current and low-voltage direct current so as to achieve the aim of hybrid driving.
Therefore, the fan blade driven by the hybrid drive utilizes the electrostatic acceleration principle to improve the working rotation speed of the motor, reduce the load of the motor and improve the working environment of the motor under the condition of not increasing the input current of the motor. Hybrid-driven micro-power devices possess higher power density and energy conversion efficiency than motor drives alone. The power device adopting the hybrid driving principle has the advantages that the output power and the energy conversion efficiency are not simple superposition of the motor and the electrostatic driving, but have a mutual enhancement effect, the electrostatic driving improves the working environment of the motor, and the motor provides a basic rotating speed for the electrostatic driving, so that the effect that 1+1 is more than 2 is realized. In other words, when the micro power device adopts the hybrid driving of the motor and the static electricity, compared with the traditional driving mode of singly adopting the motor, the amplification of the output power is not completely equal to the driving power of the introduced electrostatic force, and the factors of the motor that the energy conversion efficiency and the output power are greatly improved due to the introduction of the electrostatic force and the improvement of the working environment are also considered.
The above examples are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above examples, and any other changes, modifications, substitutions, combinations, and simplifications that do not depart from the spirit and principle of the present invention should be made in the equivalent manner, and the embodiments are included in the protection scope of the present invention.
