Abstract

The present invention provides a locking mechanism in a mobile terminal and a method of manufacturing the same. The locking mechanism comprises a slider, latch, button, and spring. The slider and latch include openings and may translate between a locked position and an unlocked position. The latch may include a protrusion that limits the translation of the slider and the latch when in the locked position. The button is located within the opening of the slider and the opening of the latch, and the spring member is fixed adjacent the latch. In an instance in which an external force is applied to the button, the external force deforms the spring member such that contact between a vertical edge of the protrusion and the spring is precluded allowing translation of the slider and the latch between the locked position and the unlocked position.

First claim

What is claimed is:

1. A locking mechanism in a mobile terminal, comprising:
a slider disposed on an exterior side of a battery cover of the mobile terminal and comprising an opening extending through the slider and configured to translate between a locked position and an unlocked position;
a latch disposed on an interior side of the battery cover of the mobile terminal and attached to the slider, wherein the latch may translate between the locked position and the unlocked position, and wherein the latch comprises a corresponding opening extending through the latch and a protrusion configured to limit translation of the slider and the latch when in the locked position;
a button disposed within the opening of the slider and the corresponding opening of the latch; and
a spring fixed adjacent the latch and the button such that the button and the latch contact the spring,
wherein in an instance in which an external force is applied to the button, the external force deforms the spring such that contact between a vertical edge of the protrusion and the spring is precluded allowing translation of the slider and the latch between the locked position and the unlocked position,
wherein the latch and the slider each extends outward of the button to provide at least one of a lip, a flange, or an extension along an exterior edge of the latch and the slider that contact an exterior surface of the battery cover and an interior surface of a back housing of the mobile terminal.

2. The locking mechanism according to claim 1 , wherein the protrusion further comprises a ramped portion proximate the vertical edge of the protrusion.

3. The locking mechanism according to claim 2 , wherein in an instance in which an external translational force is applied to the slider, the ramped portion of the protrusion contacts the spring so as to allow translation of the slider and the latch between the unlocked position and the locked position.

4. The locking mechanism according to claim 3 , wherein a point between the ramped portion and the vertical edge of the protrusion is configured such that, in the absence of the external force applied to the button deforming the spring, the point transitions the locking mechanism between the unlocked position and the locked position.

5. A method of manufacturing a locking mechanism in a mobile terminal, the method comprising:
providing a slider disposed on an exterior side of a battery cover of the mobile terminal and comprising an opening extending through the slider and configured to translate between a locked position and an unlocked position;
providing a latch disposed on an interior side of the battery cover of the mobile terminal and attached to the slider, wherein the latch may translate between the locked position and the unlocked position, and wherein the latch comprises a corresponding opening extending through the latch and a protrusion configured to limit translation of the slider and the latch when in the locked position;
providing a button disposed within the opening of the slider and the corresponding opening of the latch; and
providing a spring fixed adjacent the latch and the button such that the button and the latch contact the spring,
wherein in an instance in which an external force is applied to the button, the external force deforms the spring such that contact between a vertical edge of the protrusion and the spring is precluded allowing translation of the slider and the latch between the locked position and the unlocked position,
wherein the latch and the slider each extends outward of the button to provide at least one of a lip, a flange, or an extension along an exterior edge of the latch and the slider that contact an exterior surface of the battery cover and an interior surface of a back housing of the mobile terminal.

6. The locking mechanism according to claim 1 , wherein the latch, in the locked position, engages with at least a portion of the back housing of the mobile terminal.

7. The method according to claim 5 , wherein the latch, in the locked position, engages with at least a portion of the back housing of the mobile terminal.
