Description

BACKGROUND

1. Technical Field

The present disclosure relates to an electronic device with a rotatable door that facilitates access to components installed in the electronic device.

2. Description of Related Art

Large electronic devices usually include a chassis and a rotatable door or window attached to the chassis, for which an opening is defined in the chassis. When closed, the rotatable door seals the opening, and exposes the opening when rotated open, for accessing components in the chassis. After the rotatable door is closed the rotatable door is secured by a spring pin fastener. To open the rotatable door, the spring pin fastener must be pulled back, however, the spring pin fastener does not operate in a user-friendly fashion, and the spring pin fastener is easily worn out by repeated use.

Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION

The disclosure is illustrated by way of example and not by way of limitation. In the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.

Referring to FIG. 1, an embodiment of an electronic device includes a side panel 10, a rotatable door 20, a latch module 70, a pair of pivot posts 80, and a pair of washers 90 with an incomplete ring shape. In one embodiment, the electronic device is a computer, a server etc. The side panel 10 is a part of a chassis of the electronic device.

An opening 12 is defined in the side panel 10. A pair of first flanges 14 is bent from the upper and lower edges of the opening 12. A first pivot hole 141 is defined in each of the pair of first flanges 14. A first mounting slot 143 is defined in the upper one of the pair of first flanges 14.

The rotatable door 20 includes a main plate 24 and a pair of second flanges 22 bent from the upper and lower edges of the main plate 24. The rotatable door 20 is substantially the same size as the opening 12. A second pivot hole 221 is defined in each of the pair of second flanges 22. A second mounting slot 223 is defined in one of the pair of second flanges 22. A handle 26 is attached to the main plate 24 and located below the second mounting slot 223. The second pivot hole 221 and the second mounting slot 223 are located at opposite ends of the rotatable door 20.

Referring to FIG. 2, the latch module 70 includes a latch piece 30, a damping piece 40, a holder 50, and a slidable pin 60. A mounting hole 32 is defined in the latch piece 30. A mounting aperture 42 is defined in the central portion of the damping piece 40. A pair of protrusions 44 protrudes from the damping piece 40 and the mounting aperture 42 is located between the pair of protrusions 44. The holder 50 includes a mounting piece 52 and a pair of symmetrical side flanges 58. The side flanges 58 are L-shaped. A vertical slot 54 is defined in the central portion of the mounting piece 52. Two pairs of engaging holes 56 are defined in the mounting piece 52 and are located on either side of the vertical slot 54. An L-shaped slot 581 is defined in each of the pair of side flanges 58. A pair of tabs 34 protrudes from opposite sides of the latch piece 30. The pair of tabs 34 is slidable along the L-shaped slots 581. The slidable pin 60 includes a head 62, a connection portion 64, and a threaded end 66. The connection portion 64 is connected between the head 62 and the threaded end 66. The diameter of the connection portion 64 is less than that of the head 62. The diameter of the threaded end 66 is less than that of the connection portion 64. The diameter of the head 62 is slightly greater than the width of the vertical slot 54. The diameter of the connection portion 64 is less than the width of the vertical slot 54. The threaded end 66 can be securely engaged through the mounting aperture 42 and into the mounting hole 32.

Referring to FIGS. 3 and 4, in assembly, the rotatable door 20 is aligned with the opening 12. The pair of second pivot holes 221 is aligned with the pair of first pivot holes 141. The pair of pivot posts 80 extends into the pair of first pivot holes 141, through the holes of the washers 90, and into the pair of second pivot posts 221. Thereby, the rotatable door 20 is pivotably attached to side panel 10. The pair of protrusions 44 is engaged into the two upper engaging holes 56 to secure the damping piece 40 to the concave side of the holder 50. The pair of tabs 34 is received in the upper portions of the pair of L-shaped slots 581 and are movable along the pair of

L-shaped slots 581. The mounting hole 32 is aligned with the mounting aperture 42. The threaded end 66 extends through the vertical slot 54 and is securely engaged through the mounting aperture 42 and into the mounting hole 32, thereby securing the latch piece 30 against the rear side of the damping piece 40. The holder 50 is secured to the side panel 10 and located above the first mounting slot 143. The latch piece 30 is aligned with the first mounting slot 143.

To lock the rotatable door 20 (see FIG. 3), it is closed to the point where the first mounting slot 143 is aligned with the second mounting slot 223. The user can push the slidable pin 60 downwards along the vertical slot 54. The damping piece 40 and the latch piece 30 slide downwards together with the slidable pin 60. The pair of protrusions 44 engages into the two lower engaging holes 56. The pair of tabs 34 slides along the L-shaped slots 581 until reaching the bottom of the L-shaped slots 581. The latch piece 30 extends through the first mounting slot 143 and into the second mounting slot 223. Thus, the rotatable door 20 is locked by the latch module 70.

To open the rotatable door 20 (see FIG. 4), the user can push the slidable pin 60 upwards along the vertical slot 54. The damping piece 40 and latch piece 30 slide upwards together with the slidable pin 60 until reaching a position where the pair of protrusions 44 engages into the two upper engaging holes 56 and the latch piece 30 disengages from the second mounting slot 223 and the first mounting slot 143. Then the rotatable door 20 will have been released and can be rotated to an open position where the opening 12 is exposed for facilitating a user's access to components inside the chassis.

While the present disclosure has been illustrated by the description of preferred embodiments thereof, and while the preferred embodiments have been described in considerable detail, it is not intended to restrict or in any way limit the scope of the appended claims to such details. Additional advantages and modifications within the spirit and scope of the present disclosure will readily appear to those skilled in the art. Therefore, the present disclosure is not limited to the specific details and illustrative examples shown and described.
