Background technique

Generally, the heat dissipation components of a personal computer are bulky, the power supply, floppy disk drive, and motherboard used are large in size, or the components are improperly arranged and connected by various cables, etc., resulting in a bulky structure of the mainframe of the personal computer. Improper use of various cable connections wastes the largest proportion of space. For example, the motherboard is connected to an optical drive, hard disk drive, recorder, power supply, floppy disk drive, etc. through a cable, and the space wasted is even more than that of the motherboard, optical drive, The volume of the hard disk, etc.

In view of the shortcoming of common personal computer, thereby produced microcomputer, although this microcomputer can improve the shortcoming of above-mentioned personal computer, because general existing microcomputer is hindered by the limitation of space, some storage unit, as floppy disk drive, The hard disk drive and optical drive are arranged in the microcomputer in a stacked or misplaced manner, so that the overall volume of the microcomputer still has a certain height (thickness), so that the use of the microcomputer is subject to many restrictions, so that the microcomputer cannot be further realized. Thinning.

Utility model content

The main purpose of the utility model is to solve the problems existing in the prior art, and provide a microcomputer expansion structure.

In order to achieve the above object, the utility model adopts the following technical solutions: a microcomputer expansion structure, including a casing, and the surface of the casing has at least one long hole; a main board arranged in the casing, the One side of the main board has a central processing unit, most electronic components, storage units, and a plurality of button portions and connection ports; The slot corresponding to the elongated hole set above.

The utility model adopts the above-mentioned technical scheme to effectively improve the shortcomings of the prior art, and uses an external connection unit to expand the required interface equipment, so that the microcomputer can be further thinned.

Detailed ways

Please refer to Figures 1-3, which are respectively a three-dimensional exploded schematic view of the present utility model, a three-dimensional appearance schematic view of the present utility model, and a cross-sectional state schematic view of the present utility model. As shown in the figure: this embodiment is an example with external units on both sides of the main board. The utility model discloses an expansion structure of a microcomputer. And a second external unit 4, the first and second external units 3, 4 can be used to expand the required interface equipment, so that the microcomputer can be further thinned.

The above-mentioned casing 1 is formed by combining an upper cover 11 and a lower cover 12, and the two ends of the casing 1 are respectively provided with a front panel 13 and a rear panel 14, and the front and rear panels 13, 14 are provided with multiple There are two perforations 131, 141, and the two surfaces of the casing 1 respectively have a long hole 111, 121, and the appropriate places on the two surfaces of the casing 1 are respectively provided with fixed parts 15, 16, the fixed parts 15 and 16 can be fixing holes or fixing pins.

The main board 2 is arranged in the above-mentioned casing 1, and one side of the main board 2 has at least a central processing unit 21, a plurality of electronic components 22, a storage unit 23, and a plurality of perforations corresponding to the front and rear panels 13, 14. 131 , 141 of the button portion 24 and the connection port 25 .

The first external unit 3 is arranged at an appropriate position on one side of the motherboard 2, and one end surface of the first external unit 3 has an insertion slot 31 corresponding to the elongated hole 111 on the surface of the casing 1, and the The long hole 111 of the casing 1 is correspondingly provided with a cover 17 that closes the insertion slot 31 of the first external connection unit 2 , so that the first external connection unit 3 can achieve dustproof effect when not in use.

The second external unit 4 is disposed at an appropriate position on the other surface of the motherboard 2 , and one end surface of the second external unit 4 has a joint portion 41 corresponding to the elongated hole 121 formed on the other surface of the casing 1 . Like this, adopt above-mentioned structure just can constitute the expansion structure of a brand-new microcomputer.

Please refer to FIG. 4 , which is a schematic cross-sectional view of the utility model in use. As shown in the figure: when the utility model is used, the required interface equipment 5 can be connected with the first external unit 3 and a second external unit 4 of the microcomputer, and the interface equipment 5 can be HD, PCI- E expansion card, CD-ROM or the connecting port group that can be connected with other required equipment, carry out required expansion with this; The first and second external units 3, 4 have corresponding switching parts 51 for exchanging signals for plugging, so that the switching parts 51 on the interface device 5 can be connected with the insertion slot 31 of the first external unit 3 or (and ) the connecting portion 41 of the second external connection unit 4 is connected, and the docking portion 52 on each interface device 5 is fixedly connected with the fixed portions 15 and 16 on the two surfaces of the casing 1 respectively, so that each interface device 5 is stacked on the microcomputer On the casing 1 (or also can offer through hole on the peripheral edge of interface equipment 5 and microcomputer casing 1, and directly lock in the through hole of interface equipment 5 and microcomputer casing with fixing assembly), and each interface equipment One side of 5 can also be provided with a socket slot 53 and a fixed part 54 to provide another interface device assembly;
