A receiving groove 6 is formed on the upper surface of the stator 5. The case body 1 is provided with a through - hole 16 communicating with the receiving groove 6. The rotor 4 is rotatably installed on the inner wall of the receiving groove 6; The stator is embedded and installed inside the case body, and the rotor is embedded and installed in the inner wall of the lid. Push the lid, and the lid realizes relative rotation with the case body through the connecting member. The rotation of the lid drives the rotor to rotate. An elastic member with a "fork" - shaped structure is arranged between the rotor and the stator; The elastic member 9 includes a first connecting rod 901, a second connecting rod 902, and an elastic rod 903. The first connecting rod 901 and the second connecting rod 902 are cross - arranged. The elastic rod 903 is connected to the rotor 4, and both ends of the elastic rod 903 are respectively connected to one ends of the first connecting rod 901 and the second connecting rod 902. The other ends of the first connecting rod 901 and the second connecting rod 902 are respectively fixedly installed on the left and right inner walls of the receiving groove 6, and a "fork" - shaped structure is jointly formed among the elastic rod 903, the first connecting rod 901, and the second connecting rod 902; Since one ends of the first connecting rod and the second connecting rod are fixedly connected to the inner wall of the receiving groove, during the rotation of the lid around the rotation center, an angle is formed between the connection line of the rotation center and the fixed point of the connecting rod and the horizontal line. At this time, the elastic member is in a compressed state. When the axis of the elastic rod is below the connection line of the rotation center and the fixed point of the connecting rod, the elastic member expands to push the first stop portion, realizing the automatic closing of the lid. When the axis of the elastic rod is above the connection line of the rotation center and the fixed point of the connecting rod, the elastic member expands to push the second stop portion, realizing the automatic opening of the lid; Thus, while rotating the lid, the elastic member with a "fork" - shaped structure undergoes elastic deformation, enabling the lid to automatically continue to flip after rotating a certain angle. Utilizing the elastic deformation of the elastic member during the rotation of the rotor, the lid can automatically open and close after flipping a certain angle.

The connecting member 3 includes a mover 4 fixedly connected to the lid 1, a stator 5 embedded in the case body 2, and an elastic member 9. A storage groove 6 is formed on the upper surface of the stator 5. The case body 1 is provided with a through hole 16 communicating with the storage groove 6. The mover 4 is rotatably installed on the inner wall of the storage groove 6; By embedding the stator in the case body and the mover in the inner wall of the lid, the quick installation of the connecting member with the case body and the lid can be realized, thereby simplifying the assembly process of the flip-type earphone case and improving the production efficiency; The elastic member 9 includes a first connecting rod 901, a second connecting rod 902, and an elastic rod 903. The first connecting rod 901 and the second connecting rod 902 are cross-arranged. The elastic rod 903 is connected to the mover 4, and both ends of the elastic rod 903 are respectively connected to one ends of the first connecting rod 901 and the second connecting rod 902. The other ends of the first connecting rod 901 and the second connecting rod 902 are respectively fixedly installed on the left and right inner walls of the storage groove 6, and a clamping groove 8 for embedding and installing the elastic rod 903 is formed between the first stop portion 71 and the second stop portion 72; At the same time, through the elastic member with a "fork" shape structure between the stator and the mover, by using the elastic deformation of the elastic member during the rotation of the rotor, the lid can be automatically opened and closed after being flipped by a certain angle, and the "fork" shape structure of the elastic member is stable, which not only improves the stability of the opening and closing feel of the flip-type earphone case during long-term use, but also greatly reduces the situation of the lid closing obliquely, and also reduces the requirement for the installation space, thereby reducing the size of the stator and being beneficial to reducing the overall size of the flip-type earphone case.

[0023] A first stop portion 71 and a second stop portion 72 are provided on one side of the above-mentioned mover 4 relative to the storage groove 6, and a clamping groove 8 for embedding and installing the elastic rod 903 is formed between the first stop portion 71 and the second stop portion 72.

[0024] A first shaft hole 11 is formed through the left and right side walls of the mover 4 described above. A second shaft hole 12 corresponding to and cooperating with the first shaft hole 11 is provided on the stator 5 on both sides of the receiving groove 6.

[0028] The working principle is as follows: During use, the stator is embedded and installed inside the box body, and the mover is embedded and installed on the inner wall of the box cover. Push the box cover, and the box cover realizes relative rotation with the box body through the connecting piece. The rotation of the box cover drives the mover to rotate. An elastic member with a "fork" - shaped structure is provided between the mover and the stator; During the rotation of the mover, since one end of the first connecting rod and the second connecting rod is fixedly connected to the inner wall of the receiving groove, during the rotation of the box cover around the rotation center, an angle is formed between the line connecting the rotation center and the fixed point of the connecting rod and the horizontal line. At this time, the elastic member is in a compressed state. When the axis of the elastic rod is below the line connecting the rotation center and the fixed point of the connecting rod, the elastic member stretches to push against the first stop portion, realizing the automatic closing of the box cover. When the axis of the elastic rod is above the line connecting the rotation center and the fixed point of the connecting rod, the elastic member stretches to push against the second stop portion, realizing the automatic opening of the box cover; So that the box cover can automatically continue to flip after rotating a certain angle, and thus the box cover can automatically open and close after flipping a certain angle.

[0029] When the above - mentioned flip - type earphone box is adopted, it can realize the rapid installation of the connecting piece with the box body and the box cover, thus simplifying the assembly process of the flip - type earphone box and improving the production efficiency. At the same time, through the elastic member with a "fork" - shaped structure between the stator and the mover, by using the elastic deformation of the elastic member during the rotation of the rotor, the box cover can be automatically opened and closed after flipping a certain angle. Moreover, the "fork" - shaped structure of the elastic member is stable, which not only improves the stability of the opening and closing feel of the flip - type earphone box during long - term use, but also greatly reduces the situation of the box cover closing skew, and also reduces the requirement for the installation space, thereby reducing the size of the stator and being beneficial to reducing the overall size of the flip - type earphone box.
