Portable electronic device having a latched battery cover
View Patent ↗A portable electronic device includes a battery for providing electricity to the portable electronic device; a housing for accommodating the battery; a battery cover for covering the battery; a latch affixed to the housing in a slidable manner along a first direction, wherein when the latch is at a first position, the latch is capable of fixing the battery cover and the housing together; and an elastic unit for lifting the battery cover when the latch is at a second position.
1. A portable electronic device comprising:
a battery for providing electricity to the portable electronic device;
a housing for accommodating the battery;
a battery cover for covering the battery with a plurality of catch hooks formed thereon
a latch affixed to the housing in a slidable manner along a first direction, wherein when the latch is at a first position, the latch is engaged with at least one of the plurality of catch hooks to fix the battery cover and the housing together; and
an elastic unit having a first end connected to the latch and a second end disposed under the battery cover when the latch in at the first position for lifting the battery cover when the latch is at a second position;
wherein the at least one of the plurality of catch hooks has a downwardly tapering lower end portion, which is disposed in the elastic unit when the latch is at the first position, and when the latch moves from the first position to the second position, the first end of the elastic unit is driven by the latch and produces a force pulling back the second end of the elastic unit, and the second end of the elastic unit is blocked by the downwardly tapering lower end portion of at least one of the plurality of catch hooks and a force is thus produced and applied to the surface of the downwardly tapering end portion, and thus when the latch is at the second position, the battery cover is lifted up and released from the housing.
2. The portable electronic device of claim 1 further comprising a spring for pushing the latch to the first position.
3. The portable electronic device of claim 1 wherein the elastic unit is a metal elastic unit.
4. The portable electronic device of claim 1 wherein the elastic unit is a plastic elastic unit.
5. The portable electronic device of claim 1 wherein the elastic unit is of a ring shape.
6. The portable electronic device of claim 1 wherein the elastic unit is deformed when the latch leaves the first position.
7. The portable electronic device of claim 1 further comprising a latch cap fixed on the housing, the latch cap for constraining the latch in a direction perpendicular to the first direction.
8. A mechanism for lifting a cover when a latch is moved, comprising:
a housing;
a cover with a plurality of catch hooks for covering the housing;
a latch affixed to the housing in a slidable manner along a first direction, wherein when the latch is at a first position, the latch is engaged with at least one of the plurality of catch hooks to fix the cover and the housing together; and
an elastic unit having a first end connected to the latch and a second end disposed under the cover when the latch is at the first position for lifting the cover when the latch is at a second position;
Wherein the at least one of the plurality of catch hooks has a downwardly tapering lower end portion, which is disposed in the elastic unit when the latch is at the first position, and when the latch moves from the first position to the second position, the first end of the elastic unit is driven by the latch and produces a force pulling back the second end of the elastic unit and the second end of the elastic unit is blocked by the downwardly tapering lower end portion of at least one of the plurality of catch hooks and a force is thus produced and applied to the surface of the downwardly tapering end portion and thus when the latch is at the second position the cover is lifted up and released from the housing.
9. The mechanism of claim 8 further comprising a spring for pushing the latch to the first position.
10. The mechanism of claim 8 wherein the elastic unit is a metal elastic unit.
11. The mechanism of claim 8 wherein the elastic unit is a plastic elastic unit.
12. The mechanism of claim 8 wherein the elastic unit is of a ring shape.
13. The mechanism of claim 8 wherein the elastic unit is deformed when the latch leaves the first position.
14. The mechanism of claim 8 further comprising a latch cap fixed on the housing, the latch cap for constraining the latch in a direction perpendicular to the first direction.
