Description

  The present invention relates to the structure of a personal computer body case.

  The shape of the PC case is mainly a square box, with a fixed shelf installed on one side of the case, a PC main board attached to the side plate of the case, and PC peripherals attached to the fixed shelf. Is.

  However, since the fixed shelf is fixedly installed in the case, the fixed shelf cannot block the side plate and easily attach the main body substrate of the personal computer. Since the fixed shelf is fixedly installed in the case, when attaching the peripheral device, it must be installed in a narrow case, and the peripheral device cannot be easily attached. In addition, the surplus space inside the case is narrowed, and it is difficult to arrange the wiring for connecting the main board and the peripheral devices in this narrow space.

  Accordingly, an object of the present invention is to provide a personal computer main body case that can more conveniently and quickly perform the assembly of the main body substrate and peripheral devices and the wiring connection thereof.

PC case according to the present invention, the first case having a first surface in which the opening is formed, overlapped on the first surface of the first case, a second case for covering the opening, the A rotating shaft unit that connects the first and second cases and allows the second case to rotate; a first engagement member that is installed in the first case; and a second engagement that is installed in the second case The first engagement member includes an engagement unit that engages with the second engagement member when the first case and the second case overlap . Here, the first case further has a second surface and a third surface, and the second surface is adjacent to one side of the first surface so as to be orthogonal to the first surface, and the third surface This surface is adjacent to the other side of the first surface so as to be orthogonal to the first surface, and faces the second surface. The rotary shaft unit has a notch portion, both ends of which are in contact with the second surface and the third surface of the first case, respectively, and the rotary shaft unit is installed in the second case and cuts the rod-shaped base. An attachment member inserted into the notch, a shaft pin for fixing the attachment member in the notch, and a fixing pin for fixing the rod-shaped pedestal to the first case are included.

  According to the personal computer main body case of the present invention, the main body substrate and the peripheral devices are assembled to the first and second cases, respectively, so that the assembly of the main body substrate and the peripheral devices and the wiring connecting them do not interfere with each other. Can do.

  Examples of the present invention will be described below.

  1-5 is a figure explaining the personal computer main body case which is Example 1 of this invention. The personal computer main body case of the present embodiment mainly has a first case 1, a second case 2, a rotating shaft unit 3 and an engagement unit 4.

  As shown in FIGS. 1 and 2, the first case 1 has a rectangular box shape and has a first surface 11 in which an opening 110 for attaching a main body substrate 5 of a personal computer is formed. The second case 2 also has a rectangular box shape so that the PC peripheral device 50 can be incorporated, and covers the opening 110 by overlapping the first surface 11 of the first case 1.

  In the present embodiment, the first and second cases 1 and 2 are boxes having the same dimensions. The rotary shaft unit 3 connects the first and second cases 1 and 2 so that the second case 2 can rotate about the rotary shaft unit 3.

  The engagement unit 4 has a first engagement member 41 installed in the first case 1 and a second engagement member 42 installed in the second case 2. The first engagement member 41 engages with the second engagement member 42 when the first case 1 and the second case 2 overlap. The first engagement member 41 is slidable and is installed in the first case 1 in a state of being biased in one direction by the elastic member.

  The first case 1 further includes a second surface 12 and a third surface 13. The second surface 12 is adjacent to one side of the first surface 11 so as to be substantially orthogonal to the first surface 11. The third surface 13 is adjacent to the other side of the first surface 11 so as to be substantially orthogonal to the first surface 11, and faces the second surface 12. The second case 2 includes an accommodation space 20 so that a peripheral device 50 of a personal computer can be attached.

  FIG. 3 shows an exploded perspective view of the personal computer body case of the present embodiment. The rotary shaft unit 3 includes one rod-shaped pedestal 30, two attachment members 31, two shaft pins 32, and two fixed pins 33. The rod-shaped pedestal 30 is a rectangular rod, and both ends of the rod-shaped pedestal 30 are in contact with the second and third surfaces 12 and 13 of the first case 1, respectively. Notches 301 are provided near both ends of the rod-shaped base 30.

  The two attachment members 31 are respectively installed in the second case 2 and inserted into the cutout portions 301 of the bar-shaped pedestal 30. The two shaft pins 32 pass through the first case 1 and the notch 301, respectively, thereby fixing the attachment member 31 in the notch 301. The opening 110 can be exposed by rotating the second case 2 outward at a certain angle. Further, by rotating the second case 2 inward, the opening 110 can be covered so as to overlap the first case 1. The two fixing pins 33 fix the rod-shaped pedestal 30 to the first case 1 respectively.

  As shown in FIGS. 3 and 4, the first engagement member 41 of the engagement unit 4 is formed with a plurality of engagement hooks 410 and push buttons 411. The second engagement member 42 is formed in the second case 2, and the second engagement member 42 corresponds to the plurality of engagement hooks 410 and a plurality of engagements with the engagement hooks 410. The engagement hole 420 is provided. The first engagement member 41 further includes an elastic member 43 as a tension spring that is installed on one side of the first engagement member 41 and biases the first engagement member 41 in one direction. .

  As shown in FIG. 4, when the push button 411 is pushed toward one side (direction indicated by an arrow), the engagement hook 410 can release the lock with respect to the engagement hole 420. Thereby, the second case 2 can rotate outward, and the first engagement member 41 is automatically returned to the original position by the elastic member 43.

  On the contrary, the second case 2 is rotated inward to overlap the first case 1, and the push button 411 is pushed so that the engagement hook 410 passes through the engagement hole 420 and the push button is pushed. When the pressing force on 411 is released, the engagement hook 410 is engaged (locked) with the engagement hole 420 by the restoring force of the elastic member 43, and the second case 2 can be fixed to the first case 1. .

  As shown in FIG. 5, the second case 2 in which the peripheral device 50 is installed is rotated at a certain angle with the rotary shaft unit 3 as an axis and is rotated outward at a certain angle, thereby opening the opening 110 of the first case 1. The main body substrate 5 can be incorporated by exposing. The interface card can be inserted into the main board 5 without being obstructed by the peripheral device 50.

  In addition, by rotating the second case 2 toward the outside, connection of wiring between the main body substrate 5 and the peripheral device 50 is facilitated. As described above, the personal computer main body case of the present embodiment can be easily and quickly assembled without causing the main body substrate 5, the peripheral device 50, and the wiring connecting them to interfere with each other.

It is an external appearance perspective view of the personal computer main body case which is Example 1 of this invention. It is an external appearance perspective view of the personal computer main body case in the state which rotated the 2nd case outside. 3 is an exploded perspective view of a personal computer main body case of Embodiment 1. FIG. It is a figure explaining operation | movement of the engagement unit in Example 1. FIG. It is a figure explaining the opening / closing operation | movement of the 2nd case in Example 1. FIG.
