Description

1244365 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to the structure of an electronic device casing, which is a Λ electronic data processing device, and particularly relates to the combination of the electronic device casing and the peripheral device carrier. structure. [Prior technology] The hardware of a personal computer (PC) is roughly composed of a motherboard, various interfaces, floppy disk drives, hard disk drives, optical disk drives and other equipment, and these devices are installed in In a case, this case is commonly referred to as a computer case. For the convenience of assembly, the computer case is also equipped with a plurality of hardware brackets, such as a floppy disk drive, hard disk drive or optical disk drive. Peripheral devices (Computer peripheral devices). In the early days, the fixing method between the computer case and the peripheral device holder, or the peripheral device and the peripheral device holder was mostly fixed by screws. The screw fixing method can obtain the most stable bonding relationship. However, the fixing of the screws The method must use tools such as screwdrivers and more than one screw to process and assemble the program. Furthermore, sometimes the space limitation in the computer case will make it impossible to use the screw. Therefore, the related electric machine Manufacturers of casings have introduced many designs related to screw-free assembly, such as U.S. Patent Nos. 6,437,977, 6,385,036, 6,369,692, 6,370,022, and 6,141,222, which are related to computer cases and peripheral devices. The mounting design of the bracket or the peripheral equipment and the peripheral equipment bracket without screws. The screw-free design can facilitate assembly to save assembly man-hours and reduce production costs. However, after the peripheral equipment rack is assembled in the computer case, it occupies most of the space in the computer case, sometimes in the future. Hardware upgrade

Page 5 ^ 244365__ Instructions (2) ~ ---- or ,: When repairing, you must remove the base frame of each peripheral device one by one before you can enter: Replace or repair other electronic components, traditionally free The setting of the screws will still cause inconvenience when repairing or upgrading. 21 To solve the above problems, many patent cases have proposed related solutions. "For example, U.S. Patent No. 6404625, the 625 case discloses an assembly structure of a bearing mechanism and a computer casing, which includes a support base, a bearing A support frame and a rotating arm, wherein the rotating arm is pivotally connected to the support base and the supporting frame, respectively, so that the supporting frame can rotate the arm as an axis and rotate relative to the supporting base. However, the rotating arm is pivotally connected to the inner side of the support base and the carrier frame, so that the rotation angle of the carrier frame is limited, and the carrier frame does not have any fixed design at the position where it is screwed out or screwed into the support base. The electronic zero-level parts located under the carrier are still inconvenient. Rugao: State Announcement Patent No. 6 5 3 0 6 2 8 and 6 2 8 disclose a structure of an electric cymbal case, which includes a rotating base frame and a case, wherein the rotating base frame is rotatable. The relationship is combined with one side of the casing, so that the rotating beautiful frame can be screwed into or out of the casing. However, the rotating base frame does not have any fixed design, which will still cause inconvenience for replacement or repair. For example, U.S. Patent No. 6538879, the 879 case discloses an electric housing structure, which includes a frame body, a first button frame, a second button frame, a sliding structure, and a fastening device. One set of frames is locked on the frame body, and the second set of frames is rotatably combined with the first set of frames so that the first set of frames can be screwed into or out of the frame. However, for the purpose of rotation, the structure of the 879 case is quite complicated, and the first group of frames is fixed and cannot be rotated, so it is still inconvenient to install peripheral devices on the first group of frames.

1244365_ V. Description of the invention (3) For example, US Patent No. 6737577, the 577 case discloses a structure for opening the casing 'which includes a casing, a rotating plate, a sliding plate, an upper cover and a stopper' The rotating plate is connected to the casing in a rotatable relationship, so that the rotating plate can be covered on the casing or rotated outward. However, for the purpose of rotation, the rotation and positioning structure of the 577 case is quite complicated. With the advancement of science and technology, electronic devices have been developing towards miniaturization. For example, personal computers have launched mini computers that are more than half the size, and mini computers are smaller and can use limited space. The design of the computer case without screws or the rotation of the base frame is more important. In the patent case disclosed above, the design of the mini-computer with a small size is still not appropriate. [Summary of the Invention] Although the assembly structure of the computer case and the peripheral device base frame disclosed by the conventional design has a brown dew rotation design, however, the parts needed to achieve the rotation purpose are more complicated, and should be two mini-power units. There are still improvements on the casing, or there is an appropriate fixed design. Therefore, the present invention further proposes / a kind of electronic placement casing and structure. < The casing structure of an electronic device disclosed in the present invention includes a main casing and a main bearing base frame, wherein the top edge corresponding to the side of the main casing is provided with an isolated guide groove. The corresponding side is provided with a guide pin. The main load bearing base can slide into the arc guide groove correspondingly. At the end of the guide pin entering the arc guide groove, the main load base frame rotates with the guide pin as an axis. The main bearing base frame has a first position stored in the main casing and a second position rotated out of the main casing. Machine 1

Page 7 1244365 V. Description of the invention (4) ^ According to the structure of the electronic device casing disclosed in the present invention, when the main supporting base frame is inserted into the main casing, the side walls of the main casing restrict the left and right sides of the main supporting base frame ^ There are two movable parts near the arc-shaped guide groove of the main body casing. When the guide pin enters the end of the arc-shaped guide groove, the stopper can rest against the guide. The movement in the direction is free, so that the guide = 2 turns cannot be separated from the arc-shaped ㈣, and the other end of the force-bearing base frame relative to the guide pin has a movable grip, and the grip has a pair of hooks for hooking. With the fixing pin buckled on the main casing, the hook restricts the main bearing, and the base frame can move freely in the up and down direction, so that when the main supporting base frame is in the first position, it can be firmly combined with the main casing. According to the structure of the electronic device casing disclosed in the present invention, the main bearing side is pivotally connected to the main body casing in a rotatable relationship, so the main bearing spoon is fully rotated out of the main body casing, except that it can be easily replaced. Outside the assembly of peripheral devices, it is also easy to replace and repair the electronic red parts inside the main casing; when the base frame is combined with the main casing, the three-dimensional self-reliance is restricted and can be stably Combined with the main case.
