one of the first body and the second body is an input device, the other is a display device, and the display device and the input device are arranged opposite to each other.

3 . The electronic device according to claim 1 , wherein:

the first arc section and the extension section have a first height difference along a first direction;

the first stopper is disposed at a side of the extension section away from the first arc section;

the first direction and an axis of rotation of the second body have a parallel relationship; and

when the fitting member slides along the first track, the fitting member contacts with the first track along the first direction.

4 . The electronic device according to claim 3 , further comprising a mounting member and an elastic member, wherein:

the mounting member is fixed relative to the second body;

a guiding through-hole is formed on the mounting member, penetrating the mounting member in the first direction;

the fitting member is inserted in the guiding through-hole to slide relative to the second body;

the second body, the mounting member, and the base are arranged along the first direction;

the mounting member is located between the second body and the base; and

the elastic member is supported between the second body and the fitting member along the first direction to exert a constant force on the fitting member towards the base.

5 . An electronic device, comprising:

a first body;

a second body rotatably connected to the first body;

a base fixed relative to the first body, a first track being formed on the base, and a first stopper being formed on the first track; and

a fitting member, wherein, during rotation of the second body, the second body drives the fitting member to slide along the first track, when the second body rotates to a first preset angle, the fitting member contacts with the first stopper in a direction of rotation of the second body to restrict the rotation of the second body,

wherein:

the first track includes a first arc section and an extension section;

the first arc section and the extension section have a first height difference along a first direction;

a second stopper is formed at a side of the extension section adjacent to the first arc section; and

when the second body rotates back from the first preset angle by a first angle, the fitting member contacts with the second stopper, such that the fitting member breaks away from the extension section and enters a second track.

6 . The electronic device according to claim 5 , wherein:

the second track is formed on the base;

the second track includes an initial section and a second arc section;

the initial section and the extension section have a second height difference in the first direction;

with the assistance of the second height difference, the fitting member breaks away from the extension section and enters the second track; and

the second body drives the fitting member to slide along the second track to a second angle.

7 . The electronic device according to claim 6 , wherein:

a third arc section is formed on a side of the initial section away from the extension section;

the initial section and the third arc section have a third height difference along the first direction;

the third arc section is connected to the second arc section;

the second arc section and the third arc section form a part of a third track; and

the second body drives the fitting member to slide along the third track to contact with the first body.

8 . The electronic device according to claim 6 , wherein:

the initial section and the second arc section have a fourth height difference along the first direction;

when the second body is opened relative to the first body, the fitting member enters the second arc section from the initial section;

when the second body is closed relative to the first body, the fourth height difference restricts the fitting member to move from the second arc section back to the initial section.

9 . The electronic device according to claim 6 , wherein:

the extension section, the initial section, and the third arc section are sequentially arranged radially along a rotation axis of the second body.

10 . A method of operating an electronic device including a first body and second body arranged opposite each other, comprising:

in response to opening the second body relative to the first body, driving, by the second body, a fitting member to slide along a first track;

in response to the second body rotating to a first preset angle, driving, by the second body, in a direction of rotation of the second body, the fitting member to contact with a first stopper to restrict the rotation of the second body; and

in response to the second body rotating back from the first preset angle by a first angle, driving, by the second body, the fitting member to contact with a second stopper, such that the fitting member enters a second track to facilitate the second body to continue to rotate relative to the first body.

11 . The method according to claim 10 , further comprising:

in response to the second body continuing to rotate to a second preset angle, driving, by the second body, in the direction of rotation of the second body, the fitting member to contact with a third stopper to restrict the rotation of the second body, the second preset angle being greater than the first preset angle.

12 . The method according to claim 11 , further comprising:

in response to the second body rotating back from the second preset angle by a second angle, driving, by the second body, the fitting member to contact with a fourth stopper, such that the fitting member enters a third track to facilitate the second body to continue to rotate relative to the first body.

13 . The method according to claim 12 , further comprising:

in response to the second body continuing to rotate, driving, by the second body, in the direction of rotation of the second body, the fitting member to contact with the first body.
