Abstract

According to an embodiment, an electronic device comprises: a housing comprising an opening; a cover for opening and closing the opening; and a link structure located inside the housing and connected to the cover, wherein the link structure may comprise: an actuator configured to output power based on the temperature sensed inside the housing; a first link configured to move in a first direction by means of the power; a second link having a resilient structure that, in response to the movement of the first link, is configured to transmit the power in a second direction perpendicular to the first direction and comprises a first spring and a second spring having different elastic forces; and a third link connected to the second link and the cover and configured to convert the cover from a closed state to an open state by transmitting the power in the first direction and a third direction perpendicular to the second direction.

Claims (32)

1 . An electronic device comprising:

a housing comprising an opening;

a cover configured to open or close the opening; and

a link structure positioned inside the housing and connected to the cover,

wherein the link structure comprises:

an actuator configured to output power based on a temperature detected inside the housing;

a first link configured to move in a first direction by the power;

a second link configured to transmit the power in a second direction perpendicular to the first direction in response to a movement of the first link and including an elastic structure comprising a first spring and a second spring, each of the first and second springs having different elastic forces; and

a third link connected to the second link and the cover and configured to transmit the power in a third direction perpendicular to the first direction and the second direction to switch the cover from a closed state to an open state.

2 . The electronic device of claim 1 , wherein the second link comprises:

a first support disposed in the housing or integrally provided with the housing;

a second support positioned in a first space part of the first support, configured to be slidable in parallel to the second direction with respect to the first support, and connected to the third link; and

a shaft positioned across a second space part of the second support, the shaft having one end corresponding to the first link and another end extending from the one end, and configured to be slidable in parallel to the second direction with respect to the second support,

wherein the first spring is positioned in the first space part while being penetrated by the shaft and positioned between a first support part provided on a portion of the shaft and a side wall of the first support, the portion being provided outside the second support, the side wall facing and being spaced apart from the first support part, and

wherein the second spring is positioned in the second space part while being penetrated by the shaft and positioned between a second support part provided on the shaft and a side wall of the second support, which faces and is spaced apart from the second support part.

3 . The electronic device of claim 2 , wherein the second spring has an elastic force greater than an elastic force of the first spring,

wherein based on the first link being moved in the first direction, the shaft is configured to move in the second direction, and

wherein based on the shaft being moved in the second direction, the first spring is compressed.

4 . The electronic device of claim 2 , wherein based on the shaft being moved in the second direction, the second support is configured to move in the second direction together with the shaft in a state of being supported by the second spring, and

wherein based on the second support being moved in the second direction, the third link is configured to switch the cover from the closed state to the open state.

5 . The electronic device of claim 4 , wherein based on the cover being forcibly switched from the open state to the closed state by an external force, the second support connected to the third link is configured to move in a direction opposite to the second direction so that the second spring is compressed.

6 . The electronic device of claim 5 , wherein the link structure comprises at least one hook configured to interfere with the second support to prevent and/or inhibit the second support structure from being moved in the second direction based on the cover being forcibly switched from the open state to the closed state.

7 . The electronic device of claim 5 , wherein the housing comprises a foldable housing, and

wherein based on the foldable housing being switched from an unfolded state to a folded state, the cover is configured to be forcibly switched from the open state to the closed state.

8 . The electronic device of claim 7 , wherein the electronic device comprises a laptop computer.

9 . The electronic device of claim 2 , wherein one end of the shaft comprises a second inclined part configured to rub against a first inclined part of the first link.

10 . The electronic device of claim 1 , wherein the third link is configured to fold in a scissor action.

11 . The electronic device of claim 1 , wherein the actuator is configured to output power based on a temperature detected inside the housing being greater than or equal to a threshold value.

12 . The electronic device of claim 1 , wherein the actuator comprises at least one bimetal configured to be displaced in the first direction in reaction to heat having a specified temperature or more.

13 . The electronic device of claim 1 , wherein the actuator comprises a motor controlled by at least one processor included in the electronic device.

14 . The electronic device of claim 1 , wherein the actuator comprises a solenoid controlled by at least one processor included in the electronic device.

15 . The electronic device of claim 1 , wherein the opening comprises an air suction hole.
