Swappable battery for wearable devices
A swappable battery and a swappable battery system for a near-eye device are described. In one aspect, the swappable battery may be detachably integrated into an outer surface of a near-eye device such that the swappable battery may be easily removable and replaceable by the user. In another aspect, the lid of the swappable battery may form an outer surface of the near-eye device when the swappable battery is attached. In some examples, the swappable battery may be detachably attached within a temple arm of a pair of smartglasses such that the outer surface of the swappable battery and the outer surface of the temple arm are substantially contiguous and flush.

10 . The near-eye device of claim 8 , wherein the battery lid is detachably attached to the surface wall by a mechanical connection.
11 . The near-eye device of claim 1 , wherein
the swappable battery further comprises a battery management unit (BMU), and the battery lid extends over and covers the BMU.
12 . The near-eye device of claim 11 , wherein the swappable battery further comprises a battery electrical connection to form an electrical connection with the near-eye device.
13 . The near-eye device of claim 12 , wherein:
the battery electrical connection is to form an electrical connection between the logic board and the BMU.
14 . The near-eye device of claim 1 , wherein the near-eye device comprises a near-eye display device.
15 . The near-eye device of claim 1 , wherein the temple further comprises a battery management unit and the battery lid also covers the battery management unit.
16 . The near-eye device of claim 1 , wherein, when the battery housing is fully assembled by the battery lid and the battery enclosure, the battery cell core is sealed within the battery enclosure.
17 . A swappable battery for a near-eye device comprising:
a battery housing fully assembled by a battery lid and a battery enclosure;
a battery cell core disposed in the battery enclosure; and
the battery lid:
(i) to cover a top portion of the battery enclosure; and
(ii) have a larger size than the top portion of the battery enclosure;
the battery lid forms a portion of a surface wall of a temple of the near-eye device, wherein:
the swappable battery is detachably attachable to the surface wall of the temple of the near-eye device by integrating into the surface wall such that the battery lid forms the portion of the surface wall,
the temple includes a temple hole formed in the surface wall and the swappable battery is housed within the temple hole when detachably attached to the surface wall of the temple, and
the battery lid extends beyond the top portion of the battery enclosure such that, when the swappable battery is housed within the temple hole when detachably attached to the surface wall of the temple, the battery lid covers a logic board within the temple, the logic board configured to control electronic components of the near-eye device.
18 . The swappable battery of claim 17 , further comprising:
a battery management unit (BMU) connected to the battery enclosure, wherein the battery lid extends over and covers the BMU.
19 . A swappable battery system for a near-eye device comprising:
a frame;
a temple connected to one end of the frame, the temple comprising a surface wall and a temple hole formed in the surface wall; and
a swappable battery to detachably attach to the surface wall of the temple, the swappable battery housed within the temple hole when detachably attached to the surface wall of the temple, wherein the swappable battery comprises:
battery housing fully assembled by a battery lid and a battery enclosure;
a battery cell core disposed in the battery enclosure; and
the battery lid:
(i) to cover a top portion of the battery enclosure;
(ii) have a larger size than extend beyond the top portion of the battery enclosure; and
(iii) extends beyond the top portion of the battery enclosure such that, when the swappable battery is housed within the temple hole when detachably attached to the surface wall of the temple, the battery lid covers a logic board within the temple, the logic board configured to control electronic components of the near-eye device;
