Abstract
Description
Technical Field
[0001] This utility model relates to a cooling fan, specifically a simplified program-burning cooling fan. Background Technology
[0002] Cooling fans generally refer to fans used for cooling motherboard devices such as CPUs and graphics cards. Their main purpose is to conduct heat away and blow it into the surrounding air to achieve a cooling effect. Currently, the duty cycle, power, and speed settings of cooling fans are controlled by the MCU chip's program. Normally, the MCU chip is first programmed (or programmed), then soldered onto the PCB board. The PCB board and winding assembly form the motor assembly, and the motor assembly, fan blades, fan frame, bearings, etc., are assembled into the cooling fan. If the MCU chip's program is not programmed correctly or there is a program error, the cooling fan will malfunction. In this case, the cooling fan needs to be disassembled, the motor assembly removed, and the program reprogrammed. This process can easily damage materials; if it involves batch processing, the losses caused by material damage can be very high. For example, the patent application with application number 202022577676.0 discloses a device for writing programs to a cooling fan circuit board; however, the above-mentioned product is mainly used for batch program burning operations before the cooling fan leaves the factory. If the cooling fan has experienced an accident where the batch program was not burned or the program was burned incorrectly, and the cooling fan has already been assembled, disassembling the cooling fan will cause damage, and the chip needs to be removed to burn the program. If the program can be burned from the wire, this problem can be solved. Therefore, the prior art lacks the remedial measures and corresponding equipment and devices required for the above-mentioned cooling fan abnormalities. Summary of the Invention
[0003] To overcome the above shortcomings, the purpose of this utility model is to provide a simplified program-burning cooling fan, thereby solving the technical problem that it is inconvenient to disassemble and re-burn the program after it has been burned into existing similar cooling fans, and that there is a lack of a simple program-burning device. This objective is achieved through the following technical solution.
[0004] A simplified cooling fan for programming includes a fan frame and fan blades. The fan frame includes a central tube, and the fan blades include a fan hub and a motor assembly. The motor assembly is fixed to the outer diameter of the central tube. The fan hub includes a shaft, a bushing, and a motor housing. One end of the shaft is connected to the bushing, and the other end of the shaft has a slot. The motor assembly includes a PCB board, a winding assembly, and wires. The PCB board contains an MCU chip, and the wires extending from the PCB board have terminals at their ends. The wires are secured to the wire slots in the fan frame, and the wires extending out of the fan frame are connected to the motherboard and power supply components through the terminals. The key structural design feature is that the terminals at the wire ends of the PCB board connect to the wire interface of a programming fixture. The programming fixture includes a display screen, a power interface, a computer interface, a programming switch button, and a wire interface. Thus, the wire interface of the programming fixture mates with the terminals at the wire ends of the motor assembly to program (write) the program into the MCU chip on the PCB board.
[0005] The main body of the programming fixture is a circuit board body, which is rectangular. The wire interface of the programming fixture is located on one edge of the circuit board body, and the power interface and computer interface are located on the other symmetrical edge of the circuit board body. This structure facilitates the corresponding wiring and operation.
[0006] The programming switch button of the programming fixture is located on one edge of the circuit board body between the wire interface and the power interface and computer interface, while the display screen is located in the middle or one corner of the circuit board body. This structure facilitates the reasonable placement of the display screen and the programming switch button.
[0007] The display screen, power interface, computer interface, programming switch button, and wire interface on the circuit board body of the programming fixture are respectively extended or exposed from the outer shell.
[0008] This utility model has a simple and reasonable structural design, low production cost, convenient use and operation, and various forms and structures. It is particularly suitable for the use of burning programs into cooling fans without disassembly for remedial purposes, as well as for further improvements to similar products.

[0014] The structure and use of this utility model will now be further described with reference to the accompanying drawings. Figures 1-4 As shown, the cooling fan body 2 includes a fan frame and fan blades. The fan frame includes a central tube, and the fan blades include a fan blade hub and a motor assembly 3. The motor assembly is fixed to the outer diameter of the central tube. The fan blade hub includes a shaft, a bushing, and a motor housing. One end of the shaft is connected to the bushing, and the other end of the shaft has a slot. The motor assembly includes a PCB board 301, a winding assembly 302, and wires 303. The PCB board has an MCU chip 3011, and the ends of the wires extending from the PCB board have terminals 3031. The wires are fixed to the wire grooves in the fan frame, and the wires extending out of the fan frame are connected to the motherboard and power supply components through the terminals. The terminals of the wires on the PCB board are connected to the wire interface 105 of the programming fixture 1. The programming fixture includes a display screen 101, a power interface 102, a computer interface 103, a programming switch button 104, and a wire interface.
[0015] The specific structure of the aforementioned programming fixture is as follows: The main body of the programming fixture is a circuit board body, which is rectangular. The wire interface is located on one edge of the circuit board body, while the power interface and computer interface are located on the opposite edge of the circuit board body. The programming switch button is located on one edge of the circuit board body between the wire interface and the power and computer interfaces. The display screen is located in the middle or one corner of the circuit board body. The display screen, power interface, computer interface, programming switch button, and wire interface protrude from or are exposed on the circuit board body of the programming fixture.
[0016] When using the program, remove the faulty cooling fan from the device, connect the wire interface of the program burning fixture to the terminal of the motor assembly wire, press the start burning switch button to burn (write) the program to the MCU chip on the PCB board, and the program burning start or completion status will be displayed on the screen.
[0017] In summary, the programming method and structural design of this cooling fan eliminate the need to disassemble the fan and motor components before programming, effectively preventing material loss and improving product integrity. It not only reduces the difficulty of maintenance and the risk of failure, but also lowers maintenance costs and improves product usability.
