## Title
Electronic device with ejection mechanism

## Abstract

An electronic device includes a housing, a tray, and an ejection mechanism. The housing defines a slot and a slit in a sidewall thereof. The ejection mechanism includes a button and a pivoting member. The pivoting member includes a first end portion and a second end portion. The button includes a head portion and a shaft portion. The button is slidable along the slit between a first position where the shaft portion contacts the first end portion, the first end portion is urged by the shaft portion to move away from the sidewall, and the second end portion is leveraged to push the tray to move outwardly through the slot, and a second position where the shaft portion contacts the first end portion adjacent to the axis, the first end portion is moved, the tray is entirely received in the housing, and the second end portion abuts against the tray.

## Background
BACKGROUND
1. Technical Field
The present disclosure relates to electronic devices and, particularly, to an electronic device with an ejection mechanism.
2. Description of Related Art
Electronic devices such as notebook computer may include a tray for placing a storage card. When replacing the storage card, a pin is used to directly insert into a slit of the electronic device to trigger the ejection of the tray, but this requires a tool, concentration by the user, and a high degree of dexterity.
Therefore, what is need is an electronic device with an ejection mechanism to overcome the described limitations.

DETAILED DESCRIPTION
Referring to FIGS. 1-3, an electronic device 1 is provided. The electronic device 1 includes a housing 10. The housing 10 includes a bottom wall 102 and a sidewall 11. A slot 13 and a slit 12 are defined in the sidewall 11 of the housing 10. The electronic device 1 further includes a tray 20 aligned with the slot 13, and received in the housing 10, and an ejection mechanism 30. A storage card 2 is placed in the tray 20. The ejection mechanism 30 includes a button 301 slidably engaged in the slit 12, a first plate 302 opposite to the slit 12, and a pivoting member 310 pivotedly mounted on the bottom wall of the housing 10. In one embodiment, the electronic device 1 may be a phone, a notebook computer, or the like. The pivoting member 310 is rotatable about an axis 305 parallel to the sidewall 11. The pivoting member 310 includes a first end portion 307 and a second end portion 308. The first end portion 307 and the second end portion 308 are located at opposite side of the axis 305 and are bent toward the sidewall 11. The first end portion 307 is opposite to the slit 12. The second end portion 308 is opposite to the slot 13 and resists the tray 20.
In one embodiment, an inner surface of the sidewall 11 of the housing 10 defines a recessed portion 14. The slit 12 is defined in a portion of the recessed portion 14. The button 301 includes a base 33, a head portion 31 exposed at an outside of the housing 10, and a shaft portion 32 extending from the base 33 for contacting the first end portion 307. The head portion 31 and the shaft portion 32 are located at opposite sides of the base 33. The base 33 is movably received in the recessed portion 14. In another embodiment, a receiving groove is defined in the sidewall 11. The button 301 is only a pin. One end of the button 301 is exposed at an outside of the housing 10 via the slit 12, an opposite end is received in the receiving groove, thereby fixing the button 301 to the electronic device. When the user pushes one end of the button 301 along the slit 12, the opposite end of the button 301 moves along the receiving groove to drive the pivoting member 310 to rotate. When ejecting the tray 20, the button 301 is slidable along the slit 12 between a first position where the shaft portion 32 contacts a distal end of the first end portion 307, the first end portion 307 is urged by the shaft portion 32 to move away from the sidewall 11, and the second end portion 308 is leveraged to push the tray 20 to move outwardly through the slot 13. When pushing the tray 20 into the housing 10, a second position where the shaft portion 32 contacts an inner part of the first end portion 307 adjacent to the axis 305, the first end portion 307 is moved adjacent to the sidewall 11, the tray 20 is entirely received in the housing 10, and the second end portion 308 abuts against the tray 20.
The sidewall 11 of the housing 10 defines two first threaded holes 101. The first plate 302 defines two through holes 303 aligned with the two first threaded holes 101. The ejection mechanism 30 further includes two first screws 304. The two first screws 304 pass through the two through holes 303 and the two first axle holes 101 to fix the first plate 302 to the inner surface of the sidewall 11 of the housing 10. The first plate 302 further defines a perforation 34 whose shape matches that of the slit 12. The button 301 is slidably engaged in the slit 12 and the perforation 34.
A second threaded hole 306 is defined in the axis 305. A third threaded hole 309 is defined in an intersection between the first end portion 307 and the second end portion 308. The ejection mechanism 30 further includes a second screw 311. The second screw 311 passes through the third threaded hole 309 and the second threaded hole 306 to rotatably connect the pivoting member 310 to the axis 305.
As referred to in FIGS. 4-5, when ejecting the tray 20, the head portion 31 of the button 301 is slidable along the slit 12 between a first position where the shaft portion 32 contacts a distal end of the first end portion 307, the first end portion 307 is urged by the shaft portion 32 to move away from the sidewall 11, and the second end portion 308 is leveraged to push the tray 20 to move outwardly through the slot 13. When pushing the tray 20 into the housing 10, a second position where the shaft portion 32 contacts an inner part of the first end portion 307 adjacent to the axis 305, the first end portion 307 is moved adjacent to the sidewall 11, the tray 20 is entirely received in the housing 10, and the second end portion 308 abuts against the tray 20.
Although the present disclosure has been specifically described on the basis of the embodiments thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiments without departing from the scope and spirit of the disclosure.
