Description

Technical Field

[0001] This application relates to the field of computing device technology, and more particularly to a control board. Background Technology

[0002] The connection structure of existing control boards is often concentrated on the same wide side or randomly scattered. Not only is it difficult to adapt to small installation spaces due to its large lateral size, but it also easily leads to the mixing of power and signal interfaces, causing problems such as cable crossing and tangling, and electromagnetic interference. This increases the difficulty of assembly and maintenance, and affects the stability of signal transmission and power supply. If the board size is increased to accommodate multiple interfaces, it will also compress the internal space of the equipment, limit the integration of functions, and fail to meet the needs of compact equipment.

[0061] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0062] In related technologies, the connection structure of the control board is often concentrated on the same side. Not only is it difficult to adapt to small installation spaces due to its large lateral size, but it also easily leads to the mixing of power and signal interfaces, causing problems such as cable tangling and electromagnetic interference. This increases the difficulty of assembly and maintenance and affects the stability of signal transmission and power supply. If the board size is increased to accommodate multiple interfaces, it will also compress the internal space of the equipment, limit the integration of functions, and fail to meet the needs of compact equipment.

[0063] To address the aforementioned technical issues, the power input connection structure and power output connection structure of the control board in this application embodiment are located on opposite sides of the board body to accommodate power supplies and fans arranged on opposite sides. Functional partitioning reduces electromagnetic interference, ensures stable operation, organizes cable routing, reduces the risk of mis-insertion during assembly, and simplifies maintenance operations, eliminating the need to disassemble all cables during repairs, thus balancing space utilization and ease of use.

[0064] Specifically, the power input connection structure is used to electrically connect to the power supply, and the power output connection structure is connected to the power input connection structure to connect to the fan. The power input connection structure and the power output connection structure are located on different sides of the board body.

[0065] In one embodiment, the power input connection structure and the power output connection structure are disposed on opposite sides of the board body.

[0066] For example, the power supply input connection structure and the power supply output connection structure are respectively disposed at both ends of the board body along the first direction.

[0067] In a specific example, the power input connection structure is located at the second end of the board body along the first direction, and the power output connection structure is located at the first end of the board body along the first direction.

[0068] The following detailed description is provided with reference to specific embodiments and illustrations.

[0069] like Figures 1 to 3 As shown, the power supply input connection structure 91 and the power supply output connection structure 93 of the control board 90 are disposed at both ends of the board body 90a along the first direction.

[0070] For example, the power supply input connection structure 91 of the control board 90 can be disposed at the second end of the board body 90a along the first direction L1, and the power supply output connection structure 93 of the control board 90 can be disposed at the first end of the board body 90a along the first direction L1. The power supply input connection structure 91 is used to connect to a power source to provide operating power to the various electrical components on the control board 90 and other components (such as fans) that need to be controlled by the control board 90; the power supply output connection structure 93 is electrically connected to the power supply input connection structure 91 to connect to a fan, thereby powering the fan with the help of the power source, and controlling the fan to start, stop and speed through the control board 90 to dissipate heat from the internal components (such as circuit boards) of the computing device.

[0071] The power input connection structure 91 and the power output connection structure 93 can be plug-in connection structures. The power input connection structure 91 is electrically connected to the power supply connection interface of the power supply through a cable, and the power output connection structure 93 is electrically connected to the fan interface through a cable.

[0072] The power supply output connection structure 93 can be located adjacent to the first side of the first direction L1 of the board body 90a. There are two power supply output connection structures 93, which are arranged adjacent to each other along the second direction L2 of the board body 90a. The two power supply output connection structures 93 are used to electrically connect to the two fans respectively, so as to realize the power supply and control of the two fans.

[0073] The power supply input connection structure 91 and the power supply output connection structure 93 can be supplied with a power supply voltage of 48V, that is, the power supply voltage is 48V, in order to meet the power consumption requirements of large-size, high-speed fans.

[0074] like Figure 4 As shown, the power input connection structure 91 and the power output connection structure 93 can be electrically connected via a power supply line 90b embedded in the board body 90a. The power supply line 90b can be arranged along the edge of the board body 90a. Specifically, in the example where the power output connection structure 93 is adjacent to the first side of the first direction L1 of the board body 90a, the power supply line 90b can be arranged along the edge of the first side of the first direction L1 of the board body 90a to be spaced a certain distance from other low-level signal lines, so as to avoid high-level signals interfering with other low-level signals on the control board 90.

[0075] The power supply control connection structure 92 of the control board 90 can be located on the same side of the board body 90a as the power supply input connection structure 91. For example... Figure 1 As shown, the power supply control connection structure 92 can be set at the second end of the board body 90a along the first direction L1. The power supply control connection structure 92 is used to connect the power supply. Specifically, the power supply control connection structure 92 can be electrically connected to the power supply connection interface of the power supply through a cable to control the on and off of the power supply. The power supply can be managed according to the needs or the status of the computing device.

[0076] The power supply control connection structure 92 can be set at the second end of the board body 90a along the first direction L1, located on the second side of the power supply input connection structure 91 along the first direction L1. That is, the power supply input connection structure 91 is closer to the first side of the board body 90a along the first direction L1 and closer to the power supply output connection structure 93, so as to facilitate the arrangement of the power supply line 90b between the power supply input connection structure 91 and the power supply output connection structure 93, so that the power supply line 90b can be closer to the edge of the first side of the board body 90a along the first direction L1, thereby keeping the power supply line 90b further away from other low-level signal lines and avoiding interference with other low-level signals.

[0077] The power supply control connection structure 92 can be a plug-in connection structure, which facilitates connection to the power supply via cable.

[0078] The control board 90 may also be provided with a signal connection structure, which is used to connect to the circuit board to transmit electrical signals. The main control module 99 of the control board 90 can coordinate the chips on the circuit board to perform data interaction through the signal connection structure, carry out data calculation in an orderly manner, and complete the calculation task.

[0079] The signal connection structure and the power input connection structure may be located on different sides of the board body, and / or the signal connection structure and the power output connection structure may be located on different sides of the board body. In one embodiment, the signal connection structure, the power input connection structure, and the power output connection structure are located on different sides of the board body.

[0080] For example, the signal connection structure and the power input connection structure are respectively disposed on adjacent sides of the board body; and / or, the signal connection structure and the power output connection structure are respectively disposed on adjacent sides of the board body.

[0081] In a specific example, such as Figure 1 As shown, the signal connection structure is located on the second side of the board body 90a along the first direction L1, and the power supply input connection structure 91 and the power supply output connection structure 93 are located at both ends of the board body 90a along the first direction L1, so as to reasonably allocate the space of the board body 90a and improve the space utilization rate.

[0082] In one embodiment, there are multiple signal connection structures, which are used to connect multiple circuit boards one by one to transmit electrical signals.

[0083] In one embodiment, there are multiple signal connection structures, some of which are first signal connection structures 951 used to connect multiple circuit boards one by one, and others are second signal connection structures 952 used as backup signal connection structures.

[0084] For example, multiple signal connection structures are disposed on the second side of the board body along the first direction and arranged sequentially along the first direction.

[0085] exist Figure 1 In the example shown, the board body 90a is provided with four signal connection structures. These four signal connection structures can be connected to the four circuit boards of the computing device one by one. Alternatively, it can include three first signal connection structures 951 and one second signal connection structure 952. The three first signal connection structures 951 can be connected to the three circuit boards of the computing device respectively, and the second signal connection structure 952 can be used as a backup signal connection structure.

[0086] In a specific example, such as Figure 1As shown, a first signal connection structure 951 can be disposed on the edge of the second side of the board body 90a along the first direction L1. Multiple first signal connection structures 951 are used to connect multiple circuit boards respectively. Specifically, the multiple first signal connection structures 951 are disposed on the edge of the second side of the board body 90a along the first direction L1, arranged sequentially along the first direction L1. The first signal connection structures 951 can be electrically connected to the signal connectors of the corresponding circuit boards via cables. The arrangement of multiple first signal connection structures 951 along the length of the board body 90a and on the same side facilitates unified wiring and centralized maintenance.

[0087] The second signal connection structure 952 can serve as a backup signal connection structure. When the computing device requires higher computing power, a circuit board can be added, and the backup second signal connection structure 952 can be connected to the signal connector of the new circuit board to expand the computing task. This design provides a flexible computing power expansion interface to meet the performance requirements of different scenarios, reduce upgrade costs, and improve the scalability of computing devices.

[0088] The second signal connection structure 952 can be disposed on the edge of the second side of the board body 90a along the first direction L1, and arranged with the first signal connection structure 951 along the first direction L1. Specifically, multiple first signal connection structures 951 are arranged adjacent to each other in sequence, and the second signal connection structure 952 is arranged outside the first signal connection structure 951 at the edge. By placing the spare interface on the outside, it is convenient to access and maintain new circuit boards, avoids interference with existing connections, maintains a neat layout, and improves system maintainability and scalability.

[0089] In one embodiment, the board body further includes a third signal connection structure 953 for connecting to an external device for data transmission. For example, the third signal connection structure 953 is located on the second side of the board body 90a along the first direction L1, adjacent to the first signal connection structure 951 or the second signal connection structure 952. Figure 1 In the example shown, the third signal connection structure 953 is adjacent to the second signal connection structure 952, which facilitates connection with external devices.

[0090] The first signal connection structure 951, the second signal connection structure 952, and the third signal connection structure 953 can all be plug-in connection structures, so as to achieve fast and reliable electrical connection and signal transmission through the cooperation of plug and socket.

[0091] The plug-in connection structure of this application embodiment can be one or more of the following: pin header, female header, board-to-board connector, IDC connector, and USB interface. This application does not specifically limit it.

[0092] The control board 90 may be equipped with a network connection structure 94, which is used to establish a connection with an external network, receive various instructions and parameter configuration information from the network, and at the same time, feed back data such as the operating status and calculation results of the computing device to the external network, so as to realize bidirectional data interaction between the computing device and the external network.

[0093] The network connection structure 94 can be disposed at the first end of the board body 90a along the first direction L1, located on the second side of the power output connection structure 93 along the first direction L1. That is, both the power output connection structure 93 and the network connection structure 94 are disposed at the first end of the board body 90a along the first direction L1, and arranged sequentially along the second direction L2 of the board body 90a. Through this design of being on the same side and compactly arranged along the width direction, the integration of the two types of connection structures can be achieved without increasing the length of the board body 90a, thereby improving the space utilization of the board and enhancing the compactness of the overall structure.

[0094] An operable structure 96 may also be provided on the control panel 90, which is used by personnel to adjust the control state of the control panel 90.

[0095] like Figure 3 As shown, the operable structure 96 may include a reset button 961 and a function button 962. The reset button 961 can restore the computing device to its initial state. When the computing device freezes, malfunctions, or is misconfigured, pressing this button can restart the device and load default settings, potentially resolving the problem. The specific function of the function button 962 depends on the type and design of the device to which the control board 90 belongs. In some devices, pressing the function button 962, in conjunction with other operations (such as pressing specific number keys or key combinations), can access a specific function setting menu for configuring device parameters, switching operating modes, etc.

[0096] The operable structure 96 can be disposed at the first end of the board body 90a along the first direction L1, and adjacent to the second side of the board body 90a along the first direction L1. This operable structure 96, along with the network connection structure 94 and the power output connection structure 93, are concentrated on the same narrow side (i.e., the side along the second direction L2). This achieves high-density integration without increasing the length and width of the board body 90a, reducing space waste caused by structural dispersion, and facilitating operation, wiring, and maintenance from the same side of the device, thus improving ease of use.

[0097] The reset button 961 and function button 962 included in the operable structure 96 can be arranged vertically (perpendicular to the dimensions of the first direction L1 and the second direction L2). The vertical arrangement can utilize the height space of the board body 90a, avoid the buttons occupying too much space in the width direction (second direction L2), effectively control the size redundancy of the narrow side, and further improve the compactness of the board layout. At the same time, the vertical distribution of the buttons makes it easy for users to quickly distinguish the functions and reduce the risk of misoperation.

[0098] like Figure 3 As shown, the control board 90 may also be equipped with an indicator structure 97, which is used to visually display the operating status of the computing device to which the control board 90 belongs. The indicator structure 97 can be an indicator light, which can provide feedback on the key status of the computing device, such as operation or fault, through light signals of different colors (such as green for normal operation and red for fault) or flashing frequencies.

[0099] The indicator structure 97 can be disposed adjacent to the first end of the board body 90a along the first direction L1. The height of the indicator structure 97 can be higher than that of the operable structure 96, and the indicator structure 97 is further away from the first end of the board body 90a along the first direction L1 relative to the operable structure 96. The vertical center lines of the projections of the indicator structure 97 and the operable structure 96 onto a vertical plane perpendicular to the first direction L1 can coincide. The height difference design avoids obstruction between the indicator structure 97 and the operable structure 96 at the same horizontal position, ensuring that the indicator light signal is clearly visible and the button operation is unobstructed. The coincidence of the projection center lines achieves vertical (third direction L3) alignment of the two types of structures, which not only improves the regularity and integration of the board layout, but also aligns the corresponding exposed holes on the computing device chassis vertically, avoiding the appearance clutter caused by misaligned holes and enhancing the overall aesthetics of the device.

[0100] like Figure 4 As shown, the control board 90 may further include a first voltage conversion module 90d and a second voltage conversion module 90e. The first voltage conversion module 90d converts the high voltage of the input power supply to a low voltage, for example, converting a 48V power supply voltage to a 5V voltage, to provide power to components on the control board 90 that require low voltage (such as control chips). The second voltage conversion module 90e is used to convert the high voltage of the power supply to a power supply suitable for the operation of the RTC (Real-Time Clock), ensuring that the RTC can run continuously and record information such as time.

[0101] The main control module 99 of the control board 90 can be located in the area between the power supply input connection structure 91 and the power supply output connection structure 93. The first voltage conversion module 90d and the second voltage conversion module 90e of the control board 90 can be located at the second end of the main control module 99 along the first direction L1, that is, closer to the power supply input connection structure 91 than the main control module 99. This shortens the connection lines between the first voltage conversion module 90d and the second voltage conversion module 90e and the power supply input connection structure 91, reduces line voltage drop and transmission loss, and improves power supply efficiency. At the same time, it reduces the length of high current paths, reduces electromagnetic radiation and interference risks, and is conducive to the stable operation of the main control module 99.

[0102] Specifically, the main control module 99, the first voltage conversion module 90d, and the second voltage conversion module 90e are all arranged on the first side of the first signal connection structure 951 and the second signal connection structure 952 along the first direction L1. The first voltage conversion module 90d and the second voltage conversion module 90e are located at the second end of the main control module 99 along the first direction L1, closer to the power supply input connection structure 91. By centrally arranging the power supply modules on the side closer to the power supply input, the connection lines between the power supply modules and the power supply input connection structure 91 are shortened. At the same time, the signal modules and power supply modules are arranged in separate zones to reduce the interference of power supply noise on signal transmission and improve the overall circuit stability and anti-interference capability.

[0103] The main control module 99 may include multiple third voltage conversion modules 992, a main control chip 991, and a FLASH storage module 993, etc. The multiple third voltage conversion modules 992, the main control chip 991, and the FLASH storage module 993 included in the main control module 99 are concentrated in one area on the board.

[0104] Multiple third voltage conversion modules 992 can be used to further convert the low voltage output by the first voltage conversion module 90d into various lower voltages required by the main control chip 991. For example, the main control module 99 may include four third voltage conversion modules 992, which can further convert the 5V voltage output by the first voltage conversion module 90d into 0.8V, 1.1V, 1.8V, and 3.3V respectively to meet the power supply requirements of the main control chip 991 at different operating stages.

[0105] The main control chip 991 is responsible for processing various control commands and coordinating the collaborative work of the control board 90 and various components in the computing device; the FLASH storage module 993 is used to store program code, configuration information and operating parameters, so that the main control module 99 can start and run stably according to the preset program, thereby realizing the overall control and management of the computing device.

[0106] like Figure 2As shown, the control board 90 is also equipped with a shielding structure 90c, which covers the main control module 99 for electromagnetic shielding. This fully enclosed shielding effectively isolates the main control module 99 from external electromagnetic interference, improving signal transmission stability and anti-interference capabilities. The shielding structure 90c also provides some dustproof and physical protection, extending the service life of the main control module 99.

[0107] One of the shielding structure 90c and the plate body 90a is provided with a connecting structure, and the other is provided with a connecting mating structure. The connecting structure and the connecting mating structure are adapted to fit together to securely fix the shielding structure 90c to the plate body 90a. Specifically, as shown in... Figure 2 As shown, the shielding structure 90c can be a shielding cover, with multiple snap-fit ​​components 90c1 at its lower end; for example... Figure 4 As shown, the board body 90a has multiple engagement holes 90b1 on the outer periphery of the main control module 99. The snap-fit ​​component 90c1 can be snapped into the corresponding engagement hole 90b1 and can be further fixed by welding to ensure convenient installation and ensure that the shielding structure 90c is not easy to loosen under vibration or impact environment.

[0108] like Figure 1 and Figure 2 As shown, the control board 90 may also be equipped with a sensor connection structure 98 for connecting a temperature sensor. The temperature sensor extends into the chassis of the computing device to monitor the temperature inside the chassis. The sensor connection structure 98 serves as an interface for connecting the temperature sensor, allowing connection to a remotely located temperature sensor. The monitored internal chassis temperature data is then transmitted via cable to the main control module 99 of the control board 90, providing accurate temperature data for the main control module 99 to adjust heat dissipation (such as fan speed control).

[0109] The sensor connection structure 98 can be located adjacent to the first side of the board body 90a along the first direction L1. Compared to the second end of the board body 90a along the first direction L1, the sensor connection structure 98 can be closer to the first end. Specifically, the sensor connection structure 98 can be located adjacent to the main control module 99 and is arranged at the first end of the main control module 99 along the first direction L1. The proximity of the sensor connection structure 98 to the main control module 99 shortens the temperature signal transmission path, reduces signal attenuation and delay, and improves the temperature control response speed.

[0110] The length dimension of the control board 90 body 90a is greater than the width dimension. The length direction of the board body 90a is the first direction L1, and the width direction of the board body 90a is the second direction L2. At least some of the connecting structures are disposed at the first end of the board body 90a along the first direction L1, and at least some of the connecting structures are disposed at the second end of the board body 90a along the first direction L1.

[0111] In related technologies, control boards are mostly conventional rectangles with a width close to or greater than their length. The control board in this application embodiment is designed as a slender shape with a length greater than its width, which can flexibly adapt to narrow gaps in equipment and improve layout compatibility in compact scenarios. The connection structure is located at both ends of the control board in the length direction, which can reduce electromagnetic interference and ensure stable operation through functional partitioning, and organize cable routing and reduce the risk of mis-insertion during assembly.

[0112] The control board 90 is designed as a long and narrow shape with a length greater than its width, which reduces the space occupied in the width direction compared to a conventional wide board, thus reducing the overall width of the computing device. At the same time, the power input connection structure 91 and the power output connection structure 93 on the board body 90a are located at both ends in the length direction, that is, on the short side of the control board 90, to avoid the connection structures being concentrated on the wide side, which would result in an excessively large size in the width direction of the board. This further optimizes the overall width of the computing device and reduces layout conflicts with other components.

[0113] The ratio of the length to the width of the plate body 90a ranges from 2 to 5, for example, a ratio of 3 to 4 can be selected. Specifically, the length of the plate body 90a can be set to 171 mm and the width to 50.6 mm. By setting the length-to-width ratio of the plate body 90a within the above range, both the arrangement space for the connecting structures at both ends can be guaranteed, and the overall size of the plate body 90a can be balanced, making it better suited to other components of the computing device. This facilitates the control of the overall size of the device and its compatibility with standard-sized shelves. The above dimensional values ​​are merely examples and do not constitute a limitation of this application. Those skilled in the art can select and design according to actual needs.

[0114] The shape of the plate body 90a can be any one of the following: rectangle, elongated strip, elongated ellipse, elongated polygon, or arc-shaped elongated strip. An elongated ellipse can be understood as a structure with semicircles at both ends and a rectangle in the middle; an elongated polygon can be understood as having a polygonal outline, extending along a single direction, with the length of its major axis (length along the first direction L1) greater than its length of its minor axis (width along the second direction L2); an arc-shaped elongated strip can be understood as having an overall arc shape, with the arc length (equivalent to the length along the first direction L1) much greater than the chord height of the arc (equivalent to the width along the second direction L2). The above shapes are merely examples and do not constitute a limitation on this application. Those skilled in the art can choose and design according to actual needs.

[0115] Other configurations of the control board 90 in the above embodiments can be adopted from various technical solutions that are now and will be known to those skilled in the art, and will not be described in detail here.
