The case body 10 and the cover 20 are rotatably coupled by a hinge 30, and the hinge 30 can stably support the cover 20 when the cover 20 opens the case.

As shown in fig. 2-4, the hinge 30 includes a shaft member 1, a connecting rod 2, a crankshaft 3, and a locking mechanism. The shaft element 1 comprises a first shaft 11, a supporting element 12 and a second shaft 13, wherein the supporting element 12 is fixed on the first shaft 11, the second shaft 13 is rotatably connected with the supporting element 12, the first shaft 11 is parallel to the second shaft 13 and is arranged at intervals, and the first shaft 11 is fixed on the box body 10 and is rotatably connected with the box cover 20; the connecting rod 2 rotates to be set up in the second shaft 13, and connecting rod 2 still is equipped with rectangular spout 21, and bent axle 3 rotationally wears to locate spout 21 and bent axle 3 and lid 20 rotation are connected, and lid 20 can rotate through first axle 11 relative box body 10 to open or close box body 10, at the in-process of lid 20 relative box body 10 pivoted, lid 20 can drive bent axle 3 and connecting rod 2 synchronous motion. Specifically, as the cover 20 rotates, the crank can slide in the chute 21 and simultaneously rotate relative to the connecting rod 2, the crankshaft 3 can slide along the length direction of the chute 21 to have a first position and a second position, and when the crankshaft 3 is located at the first position, the cover 20 covers the box body 10; when the crankshaft 3 is positioned at the second position, the box cover 20 opens the box body 10, and the locking mechanism can lock the relative positions of the connecting rod 2 and the crankshaft 3 so as to keep the position of the box cover 20 at the position of opening the box body 10, so that the box has a good supporting effect; compared with the torsion spring type structure in the prior art, the structure is easy to assemble; compared with the double-shaft structure in the prior art, the assembly tolerance requirement is lower, and the matching degree of the assembled box body 10 and box cover 20 can be ensured.

It should be noted that the application of the hinge 30 in this embodiment is not limited to the earphone box, for example, the hinge 30 may also be applied to a cabinet or a case, etc., and the case may be used as an example, the first component may also be a case, and the second component may be a door correspondingly.

Alternatively, the slide groove 21 has a first end and a second end located in the longitudinal direction thereof, wherein the longitudinal direction of the slide groove 21 is shown in the ab direction in fig. 4, and the crankshaft 3 abuts against the first end when the crankshaft 3 is located at the first position; when the crankshaft 3 is in the second position, the crankshaft 3 abuts against the second end. Therefore, the rotation angle of the box cover 20 relative to the box body 10 can be limited by the lengths of the two ends of the sliding groove 21.

Preferably, when the crankshaft 3 is located at the first position, the elastic member 4 abuts against the crankshaft 3 and can restrict the movement of the crankshaft 3 to the second position. Therefore, the first position and the second position of the crankshaft 3 can be simultaneously limited by the elastic piece 4, and the relative positions of the box cover 20 and the box body 10 can be kept stable when the box body 10 is opened and closed by closing the cover. It will be appreciated that when the crankshaft 3 is in the second position, the locking mechanism maintains the locking of the relative positions of the connecting rod 2 and the crankshaft 3 by means of the elastic force, and when the external force that imparts rotation of the lid 20 relative to the case 10 exceeds a set threshold, the crankshaft 3 is able to overcome the elastic force and move towards the first position. Similarly, when the crankshaft 3 is located at the first position, the locking mechanism maintains the locking of the relative positions of the connecting rod 2 and the crankshaft 3 by means of elastic force, and when the external force for rotating the box cover 20 relative to the box body 10 exceeds a set threshold value, the crankshaft 3 can overcome the elastic force and move to the second position.

Alternatively, the locking mechanism includes two elastic members 4 protruding into the slide groove 21, wherein the slide groove 21 has a width direction as shown in cd direction in fig. 4, and the two elastic members 4 are disposed opposite to each other in the width direction of the slide groove 21. By arranging two elastic pieces 4, when the crankshaft 3 passes between the two elastic pieces 4, the two elastic pieces 4 act on the crankshaft 3 at the same time, so that the crankshaft 3 can be ensured to pass through the center, and the deflection of the position of the crankshaft 3 is avoided. Preferably, the elastic member 4 is a metal elastic sheet, and has high wear resistance. Specifically, in this embodiment, the metal spring plate is V-shaped, and two free ends of the metal spring plate are connected to the connecting rod 2, and the tip of the metal spring plate extends into the chute 21.
