Abstract
The utility model relates to a combined computer motherboard which is characterized in that the combined computer motherboard comprises two circuit boards, wherein a computer central processor, a north bridge chip an a memory are integrated on one of the circuit boards, and are connected through high-density printing circuits; a south bridge chip, plate carrying memory , a BIOS circuit and a patulous surrounding I/O interface are integrated on the other circuit board, and are connected through high-density printing circuits on the circuit boards; and the circuit boards are cascaded through a flexible circuit board. By disassembling a computer motherboard into the two circuit boards, the size of a single circuit board is reduced by reducing elements on the circuit boards. The two circuit boards are connected by the flexible circuit board, which is convenient to integrate clothes, helmets and other micro intelligent equipment with equipment with high needs for motherboard areas.
Description
Technical field
The utility model relates to a kind of modular computer mainboard, and the electronic component on the common computer motherboard is distributed on two different circuit boards according to function, and two circuit boards connect communication by flexible cable.The modular computer mainboard is realized the computer motherboard functions with the combination of two circuit boards, can reduce the size of monolithic hard circuit board, is convenient to carry or carries out integrated with the narrow and small equipment in other space.
Background technology
At present, general computer motherboard all is to have functions such as data operation, signal transmission, system management by what CPU, north bridge chips, South Bridge chip and other electric component group became.Usually the MiniITX of microcomputer mainboard employing is of a size of 170mm*170mm, Nano ITX is of a size of 120mm*120mm, minimum Pico ITX size also has 100mm*72mm, because element is more, computer motherboard often has bigger area, is difficult to by increasing the circuit board number of plies, improve wiring density, dwindling methods such as line width and distance and reduce the computer motherboard area.And many concrete application such as wearable computer need back on the body computing machine, or are integrated in the clothes; A lot of small intelligent equipment also need integrated high-performance computer mainboard be as the platform of information processing in narrow space, and these equipment also propose very high requirement because its service condition is relatively harsher to the computing machine volume.Adopt the computer motherboard of common-use size design often to be difficult to these requirements for special equipment.
The utility model content
Excessive for overcoming the existing computer motherboard area of common-use size design that adopts, the deficiency that can't in clothes or small intelligent equipment, use, the utility model provides a kind of modular computer mainboard.By element on the computer motherboard and circuit are divided into two parts, be loaded on two circuit boards, to reduce number of elements integrated on the single circuit board, dwindle the size of single circuit board, the relatively more nervous equipment in mainboard and clothes, multifunctional helmet or other space of being convenient to carries out integrated.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of modular computer mainboard, it is characterized in that: described modular computer mainboard comprises two circuit boards, wherein be integrated with central processing unit (CPU), north bridge chips and internal memory on a circuit board, connect by the P.e.c. on the circuit board between them; Be integrated with South Bridge chip on another piece circuit board, plate carries the peripheral I/O interface of storage, BIOS circuit and expansion, connect by the P.e.c. on the circuit board between them; Two circuit boards carry out cascade by flexible PCB.
The beneficial effects of the utility model are by computer motherboard being split as two circuit boards, by reducing the components and parts on the single circuit board, to reduce the monolithic circuit board size.Two circuit boards connect by flexible PCB, are convenient to can carry out integrated to the very high equipment of mainboard area requirements with clothes, the helmet and other miniature intelligence equipment.
Below in conjunction with the drawings and specific embodiments the utility model is further specified, but and do not mean that restriction the utility model protection domain.
