Auxiliary body with securing mechanism and portable electronic device using the same

1. A portable electronic device comprising:

a main body defining a locking hole therein; and

an auxiliary body comprising a latch therein, the latch including:

a button;

a slider including a locking portion retractably inserted into the locking hole, the slider being slidably engaged with the button in a manner that when the button is pressed along a first direction, the slider is pushed by the button to slide along a second direction perpendicular to the first direction, thereby retracting the locking portion from the locking hole; and

a spring member positioned between the button and a portion of the auxiliary body for elastically loading the button in a third direction opposite to the first direction;

wherein the button includes a pair of lug portions, each of the lug portions defines a slot therein oriented in an oblique direction relative to the first direction, and the slider forms a pair of pins slidably engaged in the slots.

2. The portable electronic device as claimed in claim 1 , wherein the button comprises a first wedge portion, the slider comprises a second wedge portion, and the first and second wedge portions are slidably mated together.

3. The portable electronic device as claimed in claim 1 , wherein the main body defines a pair of channels therein, the auxiliary body forms a pair of plugs, and the plugs are inserted into the channels along the first direction when the locking portion of the slider inserts into the locking hole of the main body.

4. A portable electronic device comprising:

a first body;

a second body detachably mounted to the first body; and

a securing mechanism for securing the second body to the first body and unlocking the second body from the first body, the securing mechanism comprising:

a pressing portion movably mounted to one of the first body and the second body for being acted on by a first force along a first direction;

a commutating portion engaged with the pressing portion configured for commutating said first force to a second force along a second direction;

a restoring portion pressing on the pressing portion for restoring the pressing portion against said first force; and

a locking portion fixed to the commutating portion, the locking portion selectively locking the second body to the first body, and releasing the second body from the first body upon being acted on by said second force;

wherein the commutating portion comprises a pin and a lug portion, a side of the lug portion has an angle formed obliquely relative to both said first and second directions, and the pin is slidable in or against the lug portion.

5. The portable electronic device as claimed in claim 4 , wherein the pressing portion protrudes from the one of the first body and second body.

6. The portable electronic device as claimed in claim 4 , wherein the lug portion defines a slot oriented in an oblique direction relative to both said first and second directions, and the pin is slidably received in the slot.

7. The portable electronic device as claimed in claim 6 , wherein the commutating portion further comprises a first wedge and a second wedge, and the first wedge and the second wedge are slidably mated together.

8. The portable electronic device as claimed in claim 7 , wherein the first wedge and the second wedge have a same gradient as the slot defined in the lug portion.

9. The portable electronic device as claimed in claim 4 , wherein the locking portion is retractable relative to the one of the first body and second body.

10. The portable electronic device as claimed in claim 4 , further comprising a pair of plugs formed on one of the first body and second body, and the other of the first body and second body defines a pair of channels therein to receive the plugs therein.

11. The portable electronic device as claimed in claim 4 , wherein the first direction is perpendicular to the second direction.
