Abstract

An electronic device includes a base, a connection device, a body, an antenna assembly, and a shield member. The body rotates to a first operating state and a second operating state relative to the base through the connection device. The shield member moves in the base to a shielding state and a non-overlapping state. When the body is in the first operating state, the body is not overlapping with the antenna assembly in a first direction, the shield member is in the non-overlapping state, and the shield member is not overlapping with the antenna assembly in the first direction. When the body is in the second operating state, the body overlaps at least a portion of the antenna assembly in the first direction, the shield member is in the shielding state, and the shield member shields between the antenna assembly and the body.

First claim

What is claimed is:

1. An electronic device, comprising:
a base;
a connection device connected to the base;
a body connected to the connection device, the body rotating to a first operating state and a second operating state relative to the base through the connection device;
an antenna assembly arranged in the base; and
a shield member arranged in the base, the shield member moving in the base to a shielding state and a non-overlapping state;
wherein:
in response to the body being in the first operating state, the body is not overlapping with the antenna assembly in a first direction, the shield member is in the non-overlapping state, and the shield member is not overlapping with the antenna assembly in the first direction; and
in response to the body being in the second operating state, the body overlaps at least a portion of the antenna assembly in the first direction, the shield member is in the shielding state, and the shield member shields between the antenna assembly and the body.

2. The device of claim 1 , wherein:
in response to the body changing from the first operating state to the second operating state, the shield member is configured to prevent the body from shielding the antenna assembly to cause a center frequency of the antenna assembly to change.

3. The device of claim 1 , wherein:
the base includes a first sliding track;
the shield member is snapped in the first sliding track; and
the shield member slides in the first sliding track to a position of the shielding state and a position of the non-overlapping state.

4. The device of claim 3 , further comprising:
a linkage movably connected to the base and rotatably connected to the shield member, the linkage being configured to drive the shield member to slide in the first sliding track.

5. The device of claim 4 , wherein:
the base includes a second sliding track;
the connection device includes:
a first connection member, a first end of the first connection member being inserted and sliding in the second sliding track, the first end of the first connection member being rotatably connected to the body, a second end of the first connection member being rotatably connected to the base, the first connection member being linked to the linkage for movement, and the first connection member being configured to drive the linkage to move;

in response to the body changing from the first operating state to the second operating state through the first connection member, the first end of the first connection member slides from a first end of the second sliding track to a second end of the second sliding track, the linkage moves as the first end of the first connection member slides and pushes the shield member to slide in the first sliding track from a position of the non-overlapping state to a position of the shielding state.

6. The device of claim 4 , further comprising:
an elastic member arranged in the first sliding track and connected to the linkage and the shield member;
wherein:
a first end of a first connection member and a first end of the linkage are arranged in a second sliding track;
in response to the body changing from the first operating state to the second operating state through the first connection member, the first end of the first connection member pushes the first end of the linkage to slide from the first end of the second sliding track to a second end of the second sliding track, a second end of the linkage rotates and pushed the shield member to slide in the first sliding track from a position of the non-overlapping state to a position of the shielding state through the elastic member, and the elastic member deforms; and
in response to the body changing from the second operating state to the first operating state through the first connection member, the first end of the first connection member slides from the second end of the second sliding track to the first end of the second sliding track, the first end of the linkage slides from the second end of the second sliding track to the first end of the second sliding track under an action of a restoration force of the elastic member, and the elastic member pulls the shield member to slide in the first sliding track from a position of the shielding state to a position of the non-overlapping state.

7. The device of claim 4 , wherein:
a first end of a first connection member and a first end of the linkage are rotatably connected in a second sliding track;
in response to the body changing from the first operating state to the second operating state through the first connection member, the first end of the linkage slides with the first connection member from the first end of the second sliding track to a second end of the second sliding track, a second end of the linkage rotates and pushes the shield member to slide in the first sliding track from a position of the non-overlapping state to a position of the shielding state; and
in response to the body changing from the second operating state to the first operating state through the first connection member, the first end of the linkage slides with the first connection member from the second end of the second sliding track to the first end of the second sliding track, and the second end of the linkage rotates to pull the shield member to slide in the first sliding track from a position of the shielding state to a position of the non-overlapping state.

8. The device of claim 1 , further comprising:
a driver connected to the shield member and configured to drive the shield member to move;
a detector configured to detect a state of the body; and
a controller electrically connected to the driver and the detector, the controller being configured to:
in response to the detector detecting that the body changing from the first operating state to the second operating state, control the driver to drive the shield member to move from a position of the non-overlapping state to a position of the shielding state; and
in response to the detector detecting that the body changing from the second operating state to the first operating state, control the driver to drive the shield member to move from a position of the shielding state to a position of the non-overlapping state.

9. The device of claim 1 , wherein:
the body includes a display screen;
the first operating state includes a landscape state; and
the second operating state includes a vertical state.

10. The device of claim 1 , wherein:
a dielectric constant of the shield member ranges from 2 to 9;
a material of the shield member includes plastic; and
the first direction is a thickness direction of the base.
