[0002] A fan is a commonly used system cooling device, often used in electronic devices to provide forced cooling. Generally, the power supply and signal feedback control of the fan must be electrically connected to the motherboard of the electronic device to transmit signals and power.

[0003] Conventional cooling fans are equipped with a driver PCB module. To connect to the port of a power PCB, the driver PCB module is typically provided with a female connector pre-set on the PCB template. This connector is then plugged into the male port of the power PCB to form an electrical connection. However, due to the flexibility of the wires connected to the female connector, the position of the female connector is random and not fixed. Therefore, manual insertion is required when inserting the female connector into the male port on the power PCB, significantly reducing assembly efficiency and increasing production costs. Therefore, the present applicant has devised a useful design and found a solution to the aforementioned problem. The technical solution to be introduced below was developed in this context.

[0007] Preferably, a plurality of air inlet holes are provided at both ends of the frame, and the frame is provided with an air outlet hole.

[0008] Preferably, the driving module includes a control chip, a resistor R1, and a capacitor C1.

[0018] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0020] In the embodiments of the present invention, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0021] Reference example Figures 1 to 3 A cooling fan that is easy to produce automatically includes a frame 1 and a cooling fan 2 disposed within the frame 1. A driving module 3 is disposed within the frame 1 and is electrically connected to the cooling fan 2 for driving the cooling fan 2 to start, stop, and change its speed. The driving module 3 is provided with a plurality of spring connectors 4. The spring connectors 4 eliminate the need for wires and female connectors, thereby fixing the connection position and facilitating an automated robotic arm to electrically connect and fix the fan's spring connectors 4 to the port of a power PCB board. This effectively improves assembly efficiency, reduces the production cost of the cooling fan, and provides the product with the advantage of being easy to produce automatically.

[0022] It is worth mentioning that a plurality of air inlet holes 11 are provided at both ends of the frame 1, and the frame 1 is provided with air outlet holes 12. When the cooling fan 2 is started, the external air is sucked into the frame 1 through the air inlet holes 11 and discharged through the air outlet holes 12.

[0023] It is worth mentioning that the driving module 3 includes a control chip 31, a resistor R1, and a capacitor C1. Port 1 of the control chip 31 is electrically connected to the FG port of the spring connector 4, port 2 of the control chip 31 is electrically connected to the GND port of the spring connector 4, port 5 of the control chip 31 is electrically connected to the PWM port of the spring connector 4, port 6 of the control chip 31 is electrically connected to one end of the resistor R1, the other end of the resistor R1 is electrically connected to one end of the capacitor C1, and the other end of the capacitor C1 is grounded. Port 6 of the control chip 31 is electrically connected to the VCC of the spring connector 4, and the power PCB board outputs a stable voltage and current to the VCC port of the spring connector 4, and the VC of the spring connector 4 Port C outputs voltage and current to the control chip 31, supplying the control chip 31 with power to operate. Resistor R1 and capacitor C1 are connected in series to prevent surge voltage protection. This protection is a protective measure designed to prevent damage or malfunction of the cooling fan 2 due to voltage anomalies (too high or too low), thereby ensuring stable operation and extending the service life of the cooling fan 2. FG is the abbreviation for frequency generator, also known as square wave or F00 wave. This waveform is a high-low rectangular signal generated during each fan cycle. The signal frequency is synchronized with the fan speed. The electrical control circuit can detect the fan speed at any time and change the rotation speed of the cooling fan 2 through the PWM duty cycle.

[0024] It is worth mentioning that the output end of the heat dissipation fan 2 is electrically connected to ports 3 and 4 of the control chip 31. The control chip 31 outputs different voltages through ports 3 and 4 to change the rotation speed of the heat dissipation fan 2.

[0025] The above design solution can enable the product to achieve the advantage of being easy to automate production.

[0026] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
