[Prior Art] The internal assembly of a traditional computer mainframe usually has a motherboard fixed in the chassis. The main board lock is fixed on the bottom plate of the chassis and connected to peripheral devices (such as power supply, interface card, data access unit, etc.) ), to form a computer that can be used with displays, keyboards, mice, etc., depending on the type of composition, including different types of desktop computers, notebook computers, tablet computers, and microcomputers; The lock fixing structure of the motherboard and the bottom plate of the computer is generally arranged at the predetermined position of the screw-solid main board when the bottom plate is stamped and formed, and a plurality of perforations are pre-set, and a stud is embedded in each perforation, and the studs are stamped one by one. The riveting process is implanted on the bottom plate, and the set holes and studs of the main board are correspondingly locked to position the main board, but in the foregoing structure, not only the work is cumbersome, the processing is time consuming, and the surface of the bottom plate is formed. The surface of the stud and the stud of the stud are recessed into the area, thus causing the surface of the bottom plate to have a high level and a low level, which is not aesthetically pleasing, and must be filled, ground, etc., and then processed to make it flat and surface. Coating and other work results in high cost and low productivity. At the same time, filling, grinding and coating paints will not only make the workers uncomfortable, but also cause environmental hazards. In addition, the computer motherboard positioning and assembly method further includes a carrier 11 in the chassis 10 (refer to the first figure), and the carrier 11 is provided with a fixing hole 110 according to the different M318745 of the motherboard 12; The motherboard 12 is placed on the carrier 11 and then locked by the positioning holes 120 of the motherboard 12 through the screws 13; in the above manner, the user needs to increase the cost of the carrier 11 and the processing cost thereof, and the carrier 11 and the bottom plate 14 of the chassis 10 need to be combined by a technique such as screwing or pressing, which is not only cumbersome, but also causes an increase in height. For a microcomputer, the volume and space occupied are increased, and the basic micro, The mini-claims are contrary to the previous, and it is not appropriate to uncover the motherboard positioning method that includes the carrier board. > Furthermore, in the positioning and assembly structure of the motherboard 12, wherein the bottom plate 14 and the front plate and the rear plate are formed as a single component, the slots and holes (not shown) between them need to be changed separately. The mold opening, its high molding, lack of maneuverability, and poor industrial utilization are necessary to improve in view of the above-mentioned shortcomings. ρ [New content] The main purpose of this creation is to provide a micro-computer motherboard positioning structure, which is located on the front side of the front panel of a micro-casing and the folding surface of the rear panel, with positioning parts, > motherboard It can be locked with the positioning piece to achieve simple and rapid molding and assembly, and the appearance of the organic shell is flat and beautiful. The secondary objective of the present invention is to provide a motherboard positioning structure of a microcomputer, wherein the upper casing and the lower casing are combined to form a hollow casing, and the front plate and the rear plate are independent components, which can be changed by The arrangement of the holes and grooves forms different types of microcomputers, which can improve the planning freedom and the adjustable margin space, and effectively reduce the development of the mold. In order to achieve the above object, the present invention relates to a motherboard positioning structure for a microcomputer, and the package 6 M318745 comprises a miniature casing, which is composed of an upper casing, a lower casing, a front plate and a rear plate, wherein the bottom edge of the front plate is provided. The utility model has an end edge which is abutting against the bottom plate of the lower casing base, and a positioning member is arranged at a predetermined position on the end edge, and the bottom plate has a folding surface extending from the bottom end thereof, and the folding surface is extended and laid on the bottom plate of the casing base, and A plurality of positioning members are arranged on the folding surface; and the main board of the computer is provided with a group hole, and the group holes are respectively locked with the positioning members of the end side and the folding surface, thereby assembling and positioning the main board quickly and easily. Through the above technical solution, the present invention can quickly locate the host B board by simple structure, effectively reduce the working time cost and create industrial benefits, and the front panel and the rear panel have better planning freedom and adjustable variable space. It can reduce the cost of development and molding, and achieve diversified and versatile products. Moreover, the new model can have a flat computer appearance without further processing, thereby simplifying the types of work and manufacturing procedures, improving production efficiency and achieving a loop. Specification requirements.
