1. An electronic device, comprising:
a shaft cover:
a device body:
a first swing arm connecting the shaft cover and the device body, wherein the first swing arm is configured to be rotatable around a first axis that is inside the shaft cover, so that the device body is folded or unfolded around the first axis;
a second swing arm distributed in parallel to the first swing arm in a direction of the first axis and coupled to a damping component that is inside the shaft cover; and
a pin connecting the first swing arm and the second swing arm at an end close to the device body, so that the second swing arm follows the first swing arm to rotate around a second axis that is inside the shaft cover when the first swing arm rotates, and the second swing arm transmits a damping force produced by the damping component to the first swing arm through the pin, wherein the first axis is parallel to the second axis;
wherein:
the first swing arm further comprises an annular groove protruding toward the second swing arm;
the second swing arm further comprises a boss protruding toward the first swing arm, wherein the boss is embedded into the annular groove in an axial direction of the pin, so that the boss and the annular groove bear part of the damping force when the second swing arm follows the first swing arm to rot;
the first swing arm is provided with a first connection lug at an end that is away from the shaft cover, and the second swing arm is provided with a second connection lug at an end that is away from the shaft cover, wherein the first connection lug is distributed in parallel to the second connection lug in the direction of the first axis;
the first connection lug is provided with a slide groove, wherein the slide groove runs through the first connection lug in the direction of the first axis;
the second connection lug is provided with a pin hole, wherein the pin hole runs through the second connection lug in the direction of the first axis, and the pin hole is located in a projection of the slide groove in the direction of the first axis; and
the pin passes through the slide groove and the pin hole, so that the first swing arm and the second swing arm form a pin-shaft connection.
