[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0029] The utility model embodiment provides an electronic device, such as Figure 1 As shown, the electronic device includes: a functional board 100 and a main board 200; the functional board 100 is arranged at a first position in the electronic device, and the main board 200 is arranged at a second position in the electronic device, and the functional board 100 and the main board 200 are connected by signals via a cable.

[0030] It should be noted that the function board 100 and the main board 200 are independently provided, and the function board 100 can be configured with common materials. Therefore, the electronic device of the utility model can reduce the size of the main board 200, integrate other components related to the external fan into the function board 100, and only need to use common materials to design the function board, thereby reducing the cost of the printed circuit board in the main board, and also reducing the design cost of the entire electronic device.

[0031] refer to Figure 1 The electronic device shown in the figure, the embodiment of the utility model provides a functional board 100 applied to the electronic device, and its structural schematic diagram is shown in Figure 2 As shown, it may specifically include:

[0032] The data connector 101 is used to connect the signal with the mainboard 200 of the electronic device through a cable. Figure 1 The Micro-H CON in the data connector 101 is connected to the mainboard 200 through a cable using a 2×48pin solution. Therefore, in the data connector 101, the interface type for signal connection with the mainboard 200 through a cable is an 8pin interface. The data connector 101 adopts a 2×4pin solution, which means that the data connector 101 includes at least 8 8pin interfaces that can send 8pin signals. Some interfaces are connected to the mainboard 200, the power controller 103, the complex programmable logic element 102 and other components according to the corresponding interface protocols, and some interfaces are directly grounded. Therefore, the interface protocols or grounding interfaces supported by the 8 8pin interfaces of the data connector 101 are: 1. I2C_SCL, 2. I2C_SDA, 3. P12V, 4. P12V, 5. P12V, 6. GND, 7. GND, 8. GND. Among them, the connection method through P12V is an electrical connection, and the P12V current capacity can support up to 36A; the connection method through I2C (including I2C_SCL and I2C_SDA) is a signal connection. The data connector 101 is a component for connecting the function board 100 and the mainboard 200 in the electronic device to realize data communication between the function board 100 and the mainboard 200.

[0033] The complex programmable logic element 102 is connected to the data connector 101 by signal, and is connected to the power controller 103 by signal, and is connected to the plurality of fan connectors 104 by signal. Figure 1The CPLD in the CPLD is connected via I2C signal connection and is electrically connected to the power controller 103 via P12V_EN. The complex programmable logic element 102 receives the application program for controlling the external fan and related data processing from the mainboard via the data connector 101. At the same time, the mainboard can also obtain the position and speed information of the external fan through the complex programmable logic element 102. The complex programmable logic element 102 is powered by the power controller 103.

[0034] The power controller 103 is signal-connected to the data connector 101, signal-connected to the complex programmable logic element 102, and electrically connected to the plurality of fan connectors 104. Figure 1 The Power IC in the embodiment is specifically an integrated power supply, which can supply power to other components. In addition to signal connection with the data connector 101, the power controller 103 can also be electrically connected to the data connector 101.

[0035] The plurality of fan connectors 104 are electrically connected to the power controller 103, and are in turn connected to the complex programmable logic element 102 by signal, and are provided with a fan interface, which can connect the connection cable of the external fan. The external fan is specifically an external fan controlled by the motherboard 200, and each fan connector 104 is connected to at least one external fan. The fan interface of the fan connector 104 includes at least a data output interface (such as Figure 1 TACH0 and TACH1 in the Figure 1 The PMW in the CPLD is used to output the speed of the external fan to the CPLD 102. The CPLD 102 is connected to the plurality of fan connector signals via a data output interface and a control interface.

[0036] The integrated circuit board 105 is used to fix the connection between the data connector 101, the complex programmable logic element 102, the power controller 103, and the fan connector 104, and realize signal and electrical connection.

[0037] In the function board of the electronic device provided by the utility model, the function board 100 and the main board 200 provided in the electronic device are provided separately. The components related to the external fan (such as complex programmable logic elements and fan connectors, etc.) are integrated on the function board. If a large number of external fans need to be controlled, it is only necessary to use ordinary materials to set corresponding fan connectors on the function board 100, without expanding the main board 200, thereby reducing the design cost related to the external fan and avoiding the expansion of the main board size.

[0038] refer to Figure 3In the functional board 100 of the electronic device, the embodiment of the utility model is applied, and the plurality of fan connectors 104 are respectively provided with corresponding protection switches 106. Each connector 104 is signal-connected to each protection switch 106 in a one-to-one correspondence.

[0039] Furthermore, the power controller 103 is electrically connected to the plurality of fan connectors through the protection switches 106. There is a signal connection between the protection switches.

[0040] It is understandable that the power controller 103 protects the Figure 3 The E-fuse in the function board 100 supplies power to each fan connector 104. The protection switch 106 can protect the external fan and the fan connector 104. If an abnormality occurs in the external fan, the connection between the fan connector 104 in the function board 100 and the power controller 103 can be disconnected.

[0041] Specifically, when the complex programmable logic element 102 makes a first signal connection with the fan connector 104, the complex programmable logic element 102 makes a second signal connection with the protection switch 106 corresponding to the fan connector 104; when the complex programmable logic element 102 makes a third signal connection with the fan connector 104, the complex programmable logic element 102 makes a fourth signal connection with the protection switch 106 corresponding to the fan connector 104.

[0042] It should be noted that the complex programmable logic element 102 can be connected to multiple protection switches 106 in sequence at the same time, or an enable signal can be sent to one protection switch 106 and then the enable signal is transmitted once between the protection switches 106 to achieve signal connection between the complex programmable logic element 102 and the protection switch.

[0043] Wherein, when the CPLD 102 is connected to the fan connector by a first signal, the external fan connected to the fan connector 104 is in normal operation. The CPLD 102 can collect the operation status of the external fan through the fan interface of the fan connector 104. If the operation status indicates that the external fan is in normal operation, the CPLD 102 connects to the fan connector 104 through the first signal; if the operation status indicates that the external fan fails, the CPLD 102 connects to the fan connector 104 through the third signal.

[0044] Furthermore, if the external fan fails, the protection switch 106 corresponding to the fan connector 104 connected to the external fan starts the protection mechanism and disconnects from the power controller 103 .

[0045] In the present invention, when the complex programmable logic element 102 is connected to the protection switch 106 for the second signal, the power controller 103 is electrically connected to the fan connector 104 to which the protection switch 106 belongs through the protection switch 106; when the complex programmable logic element 102 is connected to the protection switch 106 for the third signal, the power controller 103 is electrically disconnected from the fan connector 104 to which the protection switch 106 belongs.

[0046] When the complex programmable logic element 102 and the protection switch 106 are connected by the second signal, the protection switch 106 is in the on state; when the complex programmable logic element 102 and the protection switch 106 are connected by the third signal, the protection switch 106 is in the off state.

[0047] It should be noted that the power controller 103 can supply power to the external fan through the fan connector 104. When the complex programmable logic element 102 detects through the fan connector 104 that the operating state of the external fan is a fault, the complex programmable logic element 102 sends a fault signal to the protection switch, and the complex programmable logic element 102 switches from the second signal connection to the fourth signal connection with the protection switch 106. The protection switch 106 disconnects the electrical connection between the power controller 103 and the fan connector 104 according to the fault signal.

[0048] In an embodiment of the present application applied to a function board of an electronic device, a protection switch corresponding to each fan connector is provided to cut off the connection between the external fan and the power supply when an abnormality occurs in the external fan, thereby preventing the fault from further expanding.

[0049] In an embodiment of the present application applied to a function board of an electronic device, the fan interface of the fan connector 104 also includes a hot plug interface (such as Figure 3 The function board can be hot-swapped.

[0050] In the utility model, the data connector of the functional board is interconnected with the mainboard through a cable, using a 2x48pin solution, and the 8pin signals are: 1. I2C_SCL, 2. I2C_SDA, 3. P12V, 4. P12V, 5. P12V, 6. GND, 7. GND and 8. GND; the P12V current capacity can support up to 36A; other subsequent projects adopt this interface and signal definition, that is, the functional board can be directly reused. The I2C signal from the data connector is connected to the complex programmable logic element and the power controller on the fan board, wherein the purpose of connecting to the complex programmable logic element is to allow the mainboard to obtain and control the position and speed information of the external fan through the complex programmable logic element; the purpose of connecting to the power controller is to allow the mainboard to obtain the power consumption of the entire functional board. The enable signal of the power controller is connected to the complex programmable logic element for control, and the upstream is connected to the P12V provided by the data connector, and then the downstream is connected to the protection switch in front of each fan connector. The protection switch can protect the external fan from short circuit. The enable signal is connected to the complex programmable logic element, which can control the switch of the protection switch and realize the staggered power-on function of the external fan. The complex programmable logic element and the fan; the PRSNT#, TACH, and PWM signals of the connector are interconnected to receive and control the relevant information of the external fan.

[0051] By applying the utility model of this application, the function board is designed in the electronic device, the size of the main board can be made small, the cost of the printed circuit board is greatly reduced, and the cost of the whole machine is reduced. The function module adopts modular design, and other subsequent projects can directly evaluate and consider reuse, reducing the manpower and cycle of project development.

The present invention focuses on protecting the connection relationship between various components, and solves the technical problems in the prior art through the connection relationship introduced by the present invention and the inherent functions of various devices.

In particular, for the system or system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
