Description

electronics case

technical field

The utility model relates to an electronic device casing, which is a personal electronic data processing device, in particular to a combination structure of the electronic device casing and a peripheral device carrying frame.

Background technique

The hardware part of a personal computer (Personal Computer, PC) is roughly composed of motherboards, various interfaces, floppy disk drives, hard disk drives, optical drives, etc., and these devices are all installed in a casing. It is commonly referred to as a computer case, and for the convenience of assembly, a plurality of hardware brackets are arranged in the computer case to configure peripheral devices such as floppy disk drives, hard disk drives, or optical drives (Computer peripheral devices). In the early days, the fixing method between the computer case and the peripheral device bracket, or between the peripheral device and the peripheral device bracket was mostly fixed by screws. The screw fixing method can obtain the most stable combination relationship. However, the screw fixing method The method must use tools such as screwdrivers, and if one more screw is used, there will be one more processing and assembly procedure. Moreover, sometimes the space limitation in the computer case will make it impossible to use screws. Therefore, the manufacturers of related computer cases have introduced Many designs related to screw-free assembly, such as U.S. Patent No. 6,437,977, No. 6,385,036, No. 6,373,692, No. 6,370,022, and No. 6,141,222 patents, are related to computer casings and peripheral device brackets or peripheral equipment and peripheral equipment brackets. Assembly design without screws.

The screw-free design can facilitate assembly, save assembly man-hours and reduce production costs. However, after the peripheral device bracket is assembled on the computer case, it occupies most of the space in the computer case, and sometimes the hardware will be upgraded in the future. Or during maintenance, each peripheral device base frame must be disassembled one by one before replacement or maintenance of other electronic components. The traditional screw-free design will still cause inconvenience in maintenance or upgrade replacement.

In order to solve the above-mentioned problems, many patents propose relevant solutions: as the No. 6,404,625 patent of the U.S. Publication, this patent discloses an assembly structure of a bearing mechanism and a computer case, which includes a supporting base and a bearing frame. and a rotating arm, wherein the rotating arm is respectively pivotally connected to the support base and the bearing frame, so that the bearing frame can rotate relative to the support base using the rotating arm as an axis. However, the rotating arm is pivotally connected to the inner side of the support base and the bearing frame, so that the rotation angle of the bearing frame is limited, and the bearing frame does not have any fixed design at the position where it is screwed out or screwed into the support base. Electronic components under the carrier are still an inconvenience.

Such as U.S. Publication No. 6530628 patent, this patent discloses a computer case structure, which includes a rotating base and a casing, wherein the rotating base is combined with one side of the casing in a rotatable relationship, so that the rotating base The frame can be screwed in or out of the casing. However, the rotating pedestal does not have any fixed design, which still causes inconvenience for replacement or maintenance.

Such as U.S. Publication No. 6538879 patent, this patent discloses a kind of computer case structure, and it comprises a frame body, a first group frame, a second group frame, a sliding structure and a fastening device, wherein the first The set of frames is locked on the frame body, and the second set of frames is combined under the first set of frames in a rotatable relationship, so that the first set of frames can be screwed into or out of the frame. However, in order to achieve the purpose of rotation, the structure of this patent is quite complicated, and the first group of frames is fixed and cannot be rotated, which is still inconvenient for the peripheral devices to be installed on the first group of frames.

Such as the U.S. No. 6,737,577 patent, which discloses a shell opening structure, which includes a casing, a rotating plate, a sliding plate, an upper cover and a stopper, wherein the rotating plate is rotatable The relationship is pivotally connected to the casing, so that the rotating plate can be covered on the casing or rotated out. However, in order to achieve the purpose of rotation, the rotation and positioning structures of this patent are quite complicated.

With the advancement of science and technology, electronic devices are developing towards miniaturization. For example, personal computers have introduced mini-computers with a volume reduced by more than half, and the smaller size of mini-computers can use limited space. Therefore, for mini-computers, mini- The screw-free design of the computer case or the rotatable design of the base frame are more important, but in the above-mentioned disclosed patents, it is still not an appropriate design for a smaller mini computer.

Although the commonly disclosed assembly structure of the computer case and the peripheral device base frame has a design of open rotation, however, the parts and components required to achieve the purpose of rotation are relatively complicated, and there is still room for improvement when applied to a mini computer case, or There is no proper fixing design, so the utility model further proposes an electronic device casing and structure.
