Further, in order to realize that the elastic opening and closing assembly 4 can push the upper part shell 1 and the lower part shell 2 to be covered together, the elastic opening and closing assembly 4 comprises an upper side dislocation spring 41 and a lower side dislocation spring 41, the upper side dislocation spring 41 is divided into an upper part spring 411 and a lower part spring 412 which are arranged in a staggered mode in the upper-lower position and in opposite terminal directions, an upper end installation seat 313 is arranged below the rotating shaft installation seat 311 along the lower edge of the upper hinge 31, the tail end of the upper part spring 411 is inserted into the upper end installation seat 313 to be arranged, a spring support seat 22 extends from the bottom surface of the lower inner support 21, a spring clamping groove 221 is formed in the spring support seat 22, and the tail end of the lower part spring 412 is clamped and arranged in the spring clamping groove 221. The upper hinge 31 is pushed by the upper-lower dislocation spring 41 to rotate relative to the rotating shaft 32, so that the upper part shell 1 and the lower part shell 2 are covered together.

Further, in order to make the installation of the upper and lower side dislocation springs 41 more stable, the spring support base 22 is provided with a bottom support portion 222 extending in the direction of the upper and lower side dislocation springs 41, and the bottom support portion 222 is provided at the bottom of the end position of the lower portion springs 412.

Further, the upper and lower side dislocation springs 41 are low carbon spring wire steel.

This application design has stronger anti yield strength to the spring requirement and has guaranteed that the helping hand of hinge opening and shutting can reach the lid closing power box flip the same of better (upper limit height), still needs better toughness in order to guarantee the life that can improve the spring of opening and shutting of long-time multiple times lid. The present application uses SUS301H and low carbon spring wire steel as spring materials. The choice of wire diameter also requires knowledge of the top cover weight of our earphone charging case. For example, when the weight of the upper cover is 5-10g, a spring with a diameter of 0.4mm or less is recommended, and the ratio is that the starting wire diameter of the spring is as follows: 0.4mm, upper cover weight range: every 15g is lifted for a stage spring wire diameter to increase 0.1mm after 15g is in, and the spring wire diameter that bluetooth headset used can not exceed 0.6mm corresponding upper cover weight under the general circumstances: 45g, because there is no more than such a heavy bluetooth ear charging box cover.

When the earphone charging case is designed such that the hinge is far from the flip cover, the leverage force created by the hinge shaft 32 is great. Therefore, the distance between the positioning point in the spring hinge structure design and the axial center position of the rotating shaft 32 can be considered to be increased.

When designing such spring structures, the material weights of our charging box upper cover and upper inner support 11 are first confirmed. That is, after confirming the weight of the upper cover which needs the assistance of the spring, confirming the design of the diameter of the corner ring of the spring, and generally taking 5-7 times of the inner diameter of the spring; in order to compromise the toughness of the spring.

The positioning of the spring and the line design formed by the spring fixing points need to form a right angle with the positioning point hinge as much as possible (the right angle in the lever force is the greatest in force), and the right angle of 90 degrees cannot be completely ensured in the design because the angles formed by the front part and the rear part of the flip cover and the spring are different. When the design is needed, two states are taken into consideration, and when the design is winning, the position of the fixing point of the spring needs to be controlled, the force difference required by the cover opening and closing can be conditioned.

The experiment tests: the upper and lower side dislocation spring 41 selects low carbon steel wire diameter 0.4mm, and the pre-pressing torsion of 25 degrees (unilateral) of pre-pressing angle is: 600-650 g. The yield force per degree is between 24 and 26 g.

Definition of the amount of torsion angle of the spring when the hinge rotates: in the hinge flip process, the change of the stress extrusion amount of the spring is 10g according to the weight of the upper cover, and the initial angle between the spring and the hinge is 70 degrees. The hinge flip cover is controlled to have a 45-degree change angle, and the flip cover experiences best when the hinge flip cover is controlled to have about 7-10 degrees.

The magnet design is not used in this embodiment, can realize flip magnet two-way helping hand's function, thereby this design can reduce the magnet quantity that uses in the earphone charging box by a wide margin reduce cost.

The positioning structure of the spring is also an improved design for mold development, a side hole positioning mode of the rotating shaft 32 is not needed, and the positioning function of the spring is achieved by using the spring supporting seat 22 with misplaced upper and lower sides and the upper hinge 31, so that the space utilization rate of the charging bin is greatly improved.
