Electronic device

An electronic device comprises a housing defining an inserting slit configured to receive a memory card, a printed circuit board configured to be installed within the housing, a card reader installed in the housing and electrically coupled to the printed circuit board, and an elastic cover coupled to the housing and configured to cover the inserting slit. The card reader is configured to be substantially adjacent to the inserting slit. The elastic cover defines a slot for guiding the memory card to a receiving portion of the card reader. The elastic cover is configured to deform and expose the memory card upon depression, so that the memory card is ejected out of the housing via the slot.

FIELD

The present disclosure generally relates to an electronic device, and particularly to an electronic device capable of accepting an external memory card.

BACKGROUND

An electronic device may include memory card slots for accepting memory cards such as secure digital memory cards and trans-flash cards.

DETAILED DESCRIPTION

FIGS. 1 and 2illustrate an embodiment of an electronic device100. The electric device can include a housing10, an elastic cover20assembled to the housing10, a card reader30, and a printed circuit board40. The card reader30and the printed circuit board400can be both received in the housing10, and the card reader30can be electrically coupled to the printed circuit board40. When a memory card50is inserted into the card reader30through the elastic cover20, the card reader30can read data from the memory card50and transmit the read data to the printed circuit board40for processing.

FIGS. 3 and 4illustrate that the housing10can be substantially rectangular and include a plurality of sidewalls16. The housing10can define a substantially rectangular receiving groove13in one of the sidewalls16, and an inserting slit132can extend from a bottom of the receiving groove13into an interior space of the housing10.

The elastic cover20can be substantially rectangular. The elastic cover20can be received in the receiving groove13and cover the inserting slit132. The elastic cover20can be deformed. The elastic cover20can include a first surface22, a second surface24opposite to the first surface22, and four side surfaces26connected between the first surface22and the second surface24. The first surface22can be substantially parallel to the sidewall16that defines the receiving groove13. The second surface24can resist the bottom of the receiving groove13. The four side surfaces26can resist sides of the receiving groove13. The elastic cover20can define a pressing groove23in a substantially central portion of the first surface22. A shape of the pressing groove23can be substantially the same as a shape of the inserting slit132. The pressing groove23can include an arced bottom surface231. A strip-shaped slot232can be defined in the arced bottom surface231. The arced bottom surface231can be gradually recessed along a direction from a periphery of the pressing groove23to the slot232, and a shape of the arced bottom surface231can match a shape of a human finger. The slot232is configured for guiding the memory card50to insert into the card reader30. The elastic cover20can define an annular groove242in the second surface24. The annular groove242surrounds the slot232, and an outline of the annular groove242can match an outline of the pressing groove23. Thus, the arced bottom surface231of the pressing groove23can be deformed when the pressing groove23is pressed.

In the illustrated embodiment, the second surface24of the elastic cover20can be coated with an adhesive layer, so that the elastic cover20can be adhered to the bottom of the receiving groove13. In at least one embodiment, the elastic cover20can be made of rubber. In other embodiments, the elastic cover20can be made of metal or other elastic materials, and can be fixed in the receiving groove13with hooks. For example, sides of the receiving groove13can be equipped with hooks, and the side surface26of the elastic cover20can define latching grooves corresponding to the hooks.

In operation, the memory card50can be inserted into and latch with the card reader30through the slot232and the inserting slit132. The slot232can support and guide the memory card50to insert into the card reader30. The arced bottom surface231of the pressing groove23can be pressed to deform towards the second surface24, thereby exposing the memory card50out of the arced bottom surface231through the slot232. The memory card50can be ejected out of the slot232by being pressed by a user.

In other embodiments, the pressing groove23can be omitted, such that the slot232is defined in the first surface22of the elastic cover20, as long as the first surface22of the elastic cover20can be deformed towards the second surface24to expose the memory card50out of the first surface22.

While the present disclosure has been described with reference to particular embodiments, the description is illustrative of the disclosure and is not to be construed as limiting the disclosure. Therefore, those of ordinary skill in the art can make various modifications to the embodiments without departing from the true spirit and scope of the disclosure, as defined by the appended claims.
