Abstract

Disclosed is an electronic device which comprises: a first housing; a second housing; a support configured to couple the first housing and the second housing such that the first housing is rotatable with respect to the second housing; a spring configured to apply an elastic force to the first housing and the second housing such that one end of the first housing abuts against one end of the second housing; and a connector disposed within the first housing, wherein the first housing, the second housing, the support and the spring function as a clip capable of clamping an object between the one end of the first housing and the one end of the second housing, and wherein the connector is mechanically and electrically attachable to or detachable from a connector of an external energy harvesting module through an opening provided in a side surface of the first housing.

First claim

The invention claimed is:

1. An electronic device comprising:
a first housing;
a second housing;
a support configured to couple the first housing and the second housing such that the first housing is rotatable with respect to the second housing;
a spring configured to apply an elastic force to the first housing and the second housing such that one end of the first housing abuts against one end of the second housing; and
a connector disposed within the first housing,
wherein the first housing, the second housing, the support and the spring function as a clip capable of clamping an object between the one end of the first housing and the one end of the second housing, and
wherein the connector is mechanically and electrically attachable to or detachable from a connector of an external energy harvesting module through an opening provided in a side surface of the first housing, and
the electronic device comprising further comprising:
a rechargeable battery configured to store therein power that is supplied from the energy harvesting module via the connector;
a load circuit element capable of consuming power supplied from the energy harvesting module or power supplied from the rechargeable battery; and
a wiring board,

wherein the rechargeable battery and the wiring board are disposed within the first housing,
wherein the load circuit element is disposed on the wiring board, and
wherein the rechargeable battery is disposed between a surface of the first housing on the second housing side and the wiring board.

2. The electronic device of claim 1 , wherein the load circuit element is a light-emitting device.

3. The electronic device of claim 1 , wherein the load circuit element comprises:
a light-emitting element,
a timer configured to alternately generate a first period and a second period; and
a waveform shaping circuit configured to control a current supplied to the light-emitting element,
wherein the wave shaping circuit increases a current supplied to the light-emitting element with time during the first period, and decreases a current supplied to the light-emitting element with time during the second period.

4. The electronic device of claim 1 , wherein the second housing has a flat bottom surface or a leg.

5. The electronic device of claim 1 , wherein the first housing comprises a first clip part coupled to the support and the spring, and a cover which is attachable to and detachable from the first clip part.

6. The electronic device of claim 1 , wherein the first housing comprises:
a first clip part coupled to the support and the spring;
a cover; and
a coupling part configured to couple one end of the first clip part and one end of the cover, wherein
the cover is rotatable about the coupling part as a support with respect to the first clip part.

7. The electronic device of claim 5 , wherein the cover comprises a plurality of cover units having light transparency.

8. The electronic device of claim 1 , wherein the second housing has an adhesive portion which is adherable to an external support.
