## Background
BACKGROUND
Electronic devices have become ubiquitous the past several years. The number and types of portable computing devices, tablet, desktop, and all-in-one computers, cell, smart, and media phones, storage devices, portable media players, navigation systems, monitors and other devices has increased tremendously, and this increase shows no signs of abating.
These electronic devices may include one or more sockets and electronic components. It may be useful to provide users access to some of these sockets and electronic components. For example, it may be useful to provide access such that users may replace failed components. It may also be useful to provide access such that users may upgrade or otherwise improve existing components.
Access to these devices may be provided through components in a device enclosure, such as through doors, slots, removable covers, or other such structure. That is, a door, cover, or other such covering mechanism may be opened or removed to allow access.
Unfortunately, when these components are accessed, they may be damaged. For example, static electricity from a user may damage electrical components when they are being accessed. More importantly, users may be injured, particularly when power is being applied to the electrical components. That is, inadvertent contact between a user accessing internal electrical components of an electronic device may cause injury to the user.
To avoid this user injury, it may be desirable to prevent users from making such inadvertent contact with components that are receiving power. One way to accomplish this may be to prevent access to such components while the electronic device is being powered.
Thus, what is needed are mechanisms for electronic devices and device enclosures to prevent access by a user to electronic components in an electronic device when the electronic device is receiving power.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
FIG. 1 illustrates a portion of a device enclosure according to an embodiment of the present invention. This figure, as with the other included figures, is shown for illustrative purposes and does not limit either the possible embodiments of the present invention or the pending claims.
This figure illustrates device enclosure portion 100 having a door or other cover mechanism 110 and receptacle 120. Door 110 may be a cover, door, or other covering mechanism or structure. Door 110 may be opened or removed to allow access to sockets and electrical components located in the electronic device. These sockets and electrical components may include memory cards, graphics cards, wireless networking cards, solid-state memories, sockets for these circuits, or other components. Door 110 may open by swinging open, sliding open, or it may open in other ways.
Receptacle 120 may be a power receptacle arranged to accept a power cord. Receptacle 120 may be another type of receptacle arranged to receive power, such as a receptacle to receive power and data. In other embodiments of the present invention, receptacle 120 may be other still another type of receptacle. In this example, receptacle 120 may include prongs 144 for receiving power from a power plug. Receptacle 120 may have a rounded opening 122 to accept a conforming power plug, though in other embodiments of the present invention, receptacle 120 may have other shaped openings.
Receptacle 120 may further include button 130. Button 130 may be depressed by a user. When button 130 is released by a user, button 130 may return to a normal or up position. In other embodiments of the present invention, when button 130 is released and door 110 is closed or replaced, the closing or replacing action may drive button 130 back to the normal position. When button 130 is depressed, a locking mechanism (not shown) may allow door 110 to be opened. For example, the locking mechanism may eject or push door 110 open. When button 130 is in the normal position, a locking mechanism may lock door 110 such that it remains closed. In other embodiments of the present invention, the locking mechanism may simply not eject or open door 110.
When a power plug is inserted into receptacle 120, button 130 may not be at accessible to a user. That is, button 130 may be covered by the power plug such that the button is below a part of the power plug. Button 130 may then be located between the power plug, or portion of the power plug, and receptacle 120. In this case, when door 110 is closed, and button 130 is not accessible, a locking mechanism may lock door 110 and may not allow door 110 to be opened or removed, though other embodiments may simply not eject or open door 110. This may prevent a user from accessing components below door 110 when power is being applied to the electronic device. When the power plug is removed and power is thus removed from the electronic device, a user may access button 130. When a user depresses button 130, the locking mechanism may allow door 110 to be opened or removed, or it may eject or open door 110. When door 110 is ejected, opened, or removed, a user may access components below door 110.
FIG. 2 illustrates a receptacle housing that may be used for a receptacle according to an embodiment of the present invention. This receptacle housing may be used for receptacle 120. Receptacle 120 may include an opening 122 for a button and prongs 124 for receiving power.
FIG. 3 illustrates a view of a portion of a device enclosure from inside the device according to an embodiment of the present invention. Door 110 may be supported by frame 330. As button 130 is depressed, rotating hinges 310 and 134 may slide a bolt of opening mechanism (not shown) outward such that door 110 may be opened or removed. Clips 112 may be located around door 110 to form a solid mechanical seal.
In various embodiments of the present invention, various locking mechanisms may be used. One example is shown in the following figures.
FIG. 4 illustrates a side view of a portion of a device enclosure according to an embodiment of the present invention. In this example, door 110 may be closed, and button 130 may be in a normal state. Device enclosure portion 100 may include receptacle 120 and door 110. Receptacle 120 may include prongs 124 to receive power, for example from a wall outlet, power adapter, or other power source. Receptacle 120 may further include button 130. Button 130 may be in contact with pivoting arm 131. Printing arm 131 may pivot about pivot point 132. A distant arm of pivoting arm 131 may be connected to opening mechanism 136 at point 134.
As button 130 is depressed, pivoting arm 131 may rotate clockwise about point 132. Point 132 may be driven upward by this movement, thereby pushing opening mechanism 136 into door 110. This action may push the door 110 open. Clips 112 may be included to hold door 110 in place until opened by opening mechanism 136. Clips 112 may surround door 110 to provide a solid mechanical seal.
FIG. 5 illustrates another side view of a portion of a device enclosure according to an embodiment of the present invention. In this example, door 110 has been opened by opening mechanism 136. Specifically, button 130 has been depressed, and pivoting arm 131 has rotated about pivot point 132. This in turn has forced point 134 upwards. Point 134 in turn may drive opening mechanism 136 into door 110, which thereby may release or open door 110. Bracket 138 may provide a support structure for button 130, pivoting arm 131, and opening mechanism 136.
When door 110 is replaced, opening mechanism 136 may be lowered, thereby dropping point 134 downward and turning pivoting arm 131 in a counterclockwise direction. This may raise button 130 back to the normal or non-depressed position.
FIG. 6 illustrates a power plug according to an embodiment of the present invention. Power plug 600 may include nose 610 for insertion into socket 120. Openings 612 may accept prongs 124 in receptacle 120. Openings 612 may contain contacts that are connected to conductors 640 in power cable 630. Flange 620 may be sized to mate with, or fit into, opening 122, as shown in FIG. 1. In this way, when power plug 600 is inserted into receptacle 120, flange 620 may cover button 130. This in turn may render button 130 inaccessible to a user when power is applied to the electronic device. Since button 130 cannot be depressed when plug 600 is inserted into receptacle 120, door 110 may not be opened or removed when power is applied to the electronic device. This may in turn protect a user from voltages that may be encountered inside the electronic device when power is applied. This may also protect the internal circuits. When power plug 600 is removed, power may be removed from the device, button 130 may be depressed, and door 110 may be opened or removed.
In other embodiments of the present invention, other features may be included. For example, it may be desirable to prevent power from being applied at receptacle 120 until door 110 is closed. This may be accomplished by having button 130 or another mechanism rise from receptacle 120 when door 110 is open to prevent insertion of a power plug into receptacle 120.
The above description of embodiments of the invention has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form described, and many modifications and variations are possible in light of the teaching above. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications to thereby enable others skilled in the art to best utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. Thus, it will be appreciated that the invention is intended to cover all modifications and equivalents within the scope of the following claims.
