Fig. 1 is a schematic structural view of a storage case of the present embodiment. In the figure, the storage box is in a card punching state. Still further referring to fig. 2, the storage case in this embodiment includes a first case portion 6, a second case portion 7, and an opening and closing structure 8 connected between the first case portion 6 and the second case portion 7. When the first and second shell portions 6 and 7 are fastened together, a receiving space may be formed. The accommodating space can be used for accommodating devices such as headphones or watches.

Fig. 3 is an exploded view of the opening and closing structure 8 of the present embodiment. The first rotating portion 1 and the second rotating portion 2 in the present embodiment are rotatably connected by a rotating shaft 3. That is, the first rotating portion 1 and the second rotating portion 2 can rotate relatively. For example, the first rotating part 1 is fixedly connected with the rotating shaft 3 through a second through hole 122 on the first rotating plate 12, and the second rotating plate 22 is rotatably sleeved on the rotating shaft 3 through a third through hole 221. For another example, the rotation shaft 3 is fixedly coupled with the first through hole 62 of the first housing portion 6, and the second through hole 122 and the third through hole 221 are simultaneously rotatably coupled with the rotation shaft 3.

Fig. 4 is a schematic structural view of the elastic member 5 and the first rotating plate 12 of the present embodiment. The first rotating plate 12 is disposed at one end of the rotating shaft 3. Fig. 5, 6 and 7 are schematic structural views of the opening and closing structure 8 in this position in different embodiments. The opening and closing structure 8 in fig. 5 is in a closed state, the opening and closing structure 8 in fig. 7 is in a completely opened state, and the opening and closing structure 8 in fig. 6 is in an incompletely opened state.

Fig. 8 and 9 are schematic views of the corresponding positions of the contact cambered surface 51 and the contact body 4 in different embodiments. There are two different views in each of fig. 8 and 9. Wherein the scale of the left side view and the right side view is different. The profile of the free end 53 of the elastic element 5 in the figures is shown in bold solid lines and the profile of the first rotating plate 12 and the contact body 4 is shown in dash-dot lines. Meanwhile, the movement trace of the contact body 4 on the contact cambered surface 51 is also shown by a broken line.

In some embodiments, as shown in fig. 3 to 9, the opening and closing structure 8 in this embodiment includes a first rotating portion 1, a second rotating portion 2, and a rotating shaft 3. The first rotating part 1 includes a first connecting member 11 and a contact body 4. The second rotating part 2 is rotatably connected with the first rotating part 1 through the rotating shaft 3 and includes a second connecting member 21 and an elastic member 5, the elastic member 5 has a contact cambered surface 51, the contact cambered surface 51 is disposed opposite to the contact body 4 and has a first region 511, a second region 512 and a third region 513, the contact cambered surface 51 is bent toward one end of the rotating shaft 3, and the first region 511 and the third region 513 are close to the other end of the rotating shaft 3 with respect to the second region 512.

Meanwhile, when the first rotating portion 1 rotates relative to the second rotating portion 2, the contact body 4 abuts against the contact cambered surface 51. The elastic member 5 generates an elastic deformation amount away from the contact body 4, and the contact body 4 slides from the first region 511 to the third region 513 through the second region 512.

One particular form of contact 4 passing through the first region 511, the second region 512 and the third region 513 in sequence is shown in figures 8 and 9. In the figure, the moving track of the contact body 4 is an arc, and the center of the circle where the arc is located coincides with the rotation axis of the rotating shaft 3. The contact cambered surface 51 is located near the arc top region of the contact cambered surface 51 in the position of the second region 512 in the figure, and the region iii is a partial region of the arc top in fig. 8). In contrast, the first region 511 and the third region 513 are remote from the arc-top region. Thus, during the rotation of the first rotating portion 1 and the second rotating portion 2, the contact body 4 slides from the low point of the contact cambered surface 51 to the high point of the contact cambered surface 51, and then slides from the high point to the low point. In this process, the arc of the contact arc surface 51 can prevent the contact body 4 from scratching the surface of the elastic member 5 during multiple sliding. Meanwhile, as shown in regions i and ii in fig. 9, region i is located between the second region 512 and the third region 513, and region ii is located between the first region 511 and the second region 512. When the contact body 4 is located in the area i, the contact body 4 automatically slides down to the third area 513 under the elastic force of the elastic member 5. In contrast, when the contact 4 is located in the area ii, it automatically slides down to the first area 511. Thus, the user opening and closing actions are simplified.

In summary, in the opening and closing structure 8 of the present embodiment, the first rotating portion 1 and the second rotating portion 2 are configured to be rotatable relative to each other by using the rotating shaft 3, and the contact body 4 is abutted against the contact cambered surface 51 of the elastic member 5. Thus, on the one hand, the contact cambered surface 51 is curved toward one end of the rotating shaft 3, and when the contact body 4 slides on the contact cambered surface 51, the elastic member 5 generates elastic force acting on the contact body 4 to restrict the movement of the first and second connection members 11 and 21. Therefore, the opening and closing structure 8 is simpler, space occupation is reduced, and manufacturing cost is reduced. On the other hand, the first region 511, the second region 512, and the third region 513 are provided on the contact cambered surface 51, and the second region 512 is at a high point of the contact cambered surface 51 with respect to the first region 511 and the third region 513 in the axial direction of the rotating shaft 3. When the user closes the opening and closing structure 8, the contact body 4 can sequentially slide through the first area 511, the second area 512 and the third area 513, so that the hands of the user can feel obvious stress change, and the use experience of the user is improved. Further, the first region 511 and the third region 513 are both located at a low point of the contact cambered surface 51. Thus, after passing through the second region 512, the contact body 4 can quickly slide to the first region 511 or the third region 513, so as to increase the opening and closing speed of the opening and closing structure 8.

In some embodiments, as shown in fig. 5, the contact body 4 is a cambered protrusion. The first rotating part 1 further comprises a first rotating plate 12, the first rotating plate 12 is connected with the rotating shaft 3, and the cambered surface bulge is convexly arranged on the plate surface of the first rotating plate 12.

Specifically, the cambered surface protrusion in the embodiment is a partial spherical surface, and the contact body 4 is abutted to the contact cambered surface 51 through the vertex position of the spherical surface, so that the contact body 4 slides on the contact cambered surface 51, and the friction force between the contact body 4 and the elastic piece 5 is reduced.

In some embodiments, as shown in fig. 3, the elastic member 5 has a fixed end 52 and a free end 53, and one side of the free end 53 forms a contact cambered surface 51. Still further referring to fig. 4, the second rotating part 2 further includes a second rotating plate 22, and the second rotating plate 22 is connected to the rotating shaft 3 and is spaced apart from the first rotating plate 12. The fixed end 52 is disposed on the second rotating plate 22, and the free end 53 is disposed between the first rotating plate 12 and the second rotating plate 22 with the contact cambered surface 51 facing the first rotating plate 12. In this embodiment, the elastic member 5 is disposed on the second rotating plate 22 through the fixing end 52, so that the elastic member 5 can be driven to rotate together when the second rotating plate 22 rotates.

In some embodiments, as shown in fig. 5, the elastic member 5 has a deformation region 54. The deformation zone 54 is located between the fixed end 52 and the free end 53, and the deformation zone 54 extends from the second rotor plate 22 toward the first rotor plate 12. Still further referring to FIG. 4, the deformation zone 54 has a smaller width near the fixed end 52 than near the free end 53. The width direction of the deformation region 54 (as indicated by the arrow in fig. 4) is perpendicular to the extending direction of the deformation region 54.

The deformation area 54 in this embodiment is located between the first rotating plate 12 and the second rotating plate 22, that is, the space on opposite sides of the first rotating plate 12 and the second rotating plate 22 can be used for deforming the deformation area 54, and when the elastic member 5 deforms, the deformation area 54 drives the free end 53 to move toward the second rotating plate 22. On the other hand, the width of the deformation region 54 on the side near the fixed end 52 is smaller. When the free end 53 is pressed by the contact body 4, the side close to the fixed end 52 will be deformed preferentially, and in this form, the deformation position of the deformation region 54 is far away from the free end 53, so that the contact body 4 can generate a larger moment on the contact body, thereby facilitating the deformation of the elastic member 5 and further reducing the opening and closing force of the opening and closing structure 8.

Preferably, as shown in fig. 7, the fixed end 52 of the elastic member 5 in the present embodiment may be manufactured by a punching process. Thus, the fixed end 52 can be bent to one side, and one side surface of the fixed end 52 forms the above-described contact cambered surface 51.

In some embodiments, as shown in fig. 5-6, the fixed end 52 is fixedly connected to a side of the second rotating plate 22 away from the rotating shaft 3, the free end 53 has an arc avoidance notch 531, the first region 511, the second region 512 and the third region 513 surround the arc avoidance notch 531, the second region 512 is located between the first region 511 and the second region 512, and the arc avoidance notch 531 faces the rotating shaft 3 and is spaced from the rotating shaft 3.

The arc avoidance notch 531 in this embodiment can avoid interference between the elastic member 5 and the rotating shaft 3 during rotation. Meanwhile, the shape of the arc-shaped avoidance notch 531 is adapted to the arrangement direction of the first region 511, the second region 512 and the third region 513, so as to ensure that the contact cambered surface 51 has a sufficient area for the contact body 4 to slide thereon. The contact body 4 is prevented from sliding to the outside of the contact cambered surface 51 during sliding.

In some embodiments, as shown in fig. 3-8, the second rotating part 2 further comprises a stop 23. The opening and closing structure 8 has an open state (as shown in fig. 1). In the open state of the opening and closing structure 8, the cambered surface protrusion slides to the first region 511, and the first rotating plate 12 abuts against the stopper 23. The stopper 23 in this embodiment can limit the opening width of the opening and closing structure 8, and can prevent the contact body 4 from sliding from the first region 511 toward the edge of the contact cambered surface 51, resulting in separation from the free end 53.

In some embodiments, as shown in fig. 7, the first rotating plate 12 has a locating plate edge 121. The stopper 23 includes two long sides 231 and two short sides 232 arranged at intervals, the two short sides 232 and the two long sides 231 are connected end to form a stopper hole 233, and the extending direction of the short sides 232 is consistent with the thickness direction of the positioning plate edge 121.

The stopper 23 is disposed adjacent to the elastic member 5, and the contact body 4 slides from the second region 512 to the third region 513, and the positioning plate edge 121 moves into the stopper hole 233 until abutting against one of the short sides 232.

Specifically, the second rotating portion 2 in the present embodiment further includes a body 24. The stop 23 constitutes a stop ring by two long sides 231 and two short sides 232. The stop ring, the second rotating plate 22 and the body 24 are manufactured by an integral molding process.

The positioning plate edge 121 can be clamped in the stop ring during the opening process of the opening and closing structure 8, so as to limit the opening and closing amplitude of the opening and closing structure 8. Meanwhile, the connecting structure of the stop ring and the body 24 can improve the rigidity of the second rotating part 2, and avoid deformation of the stop ring when the positioning plate edge 121 is abutted against the stop ring. Still further referring to fig. 6, the stop hole 233 is in a strip shape, and the opening and closing structure 8 is in an incompletely opened state, in which a partial area of the positioning plate edge 121 has already been extended into the stop hole 233. Thereby, the positioning plate edge 121 can be prevented from interfering with the stopper 23 during the swinging.

In an alternative implementation, the opening and closing structure 8 in the above embodiment may be applied to the storage case. As shown in fig. 1 to 9, the storage box in this embodiment includes a first shell portion 6, a second shell portion 7, and an opening and closing structure 8.

The opening and closing structure 8 comprises a rotating shaft 3, a first rotating part 1 and a second rotating part 2, wherein the first rotating part 1 comprises a first connecting piece 11 and a contact body 4, and the second rotating part 2 is rotationally connected with the first rotating part 1 through the rotating shaft 3 and comprises a second connecting piece 21 and an elastic piece 5.

The first connecting member 11 is fixedly connected with the first shell portion 6, the second connecting member 21 is fixedly connected with the second shell portion 7, the elastic member 5 has a contact cambered surface 51, the contact cambered surface 51 is arranged opposite to the contact body 4 and has a first region 511, a second region 512 and a third region 513, the contact cambered surface 51 is bent toward one end of the rotating shaft 3, and the first region 511 and the third region 513 are close to the other end of the rotating shaft 3 relative to the second region 512.

The first rotating part 1 rotates relative to the second rotating part 2, the contact body 4 contacts the contact cambered surface 51, the elastic member 5 generates an elastic deformation away from the contact body 4, and the contact body 4 slides from the first region 511 to the third region 513 through the second region 512.

Meanwhile, when the contact body 4 is located in the first region 511, the first and second shell portions 6 and 7 are spaced apart from each other. When the contact body 4 is positioned in the third region 513, the first shell portion 6 snaps into engagement with the second shell portion 7.

In the storage case of the present embodiment, the first rotating portion 1 and the second rotating portion 2 are arranged to be rotatable with respect to each other by the rotating shaft 3, and the contact body 4 is abutted against the contact arc surface 51 of the elastic member 5. Thus, on the one hand, the contact cambered surface 51 is curved toward one end of the rotating shaft 3, and when the contact body 4 slides on the contact cambered surface 51, the elastic member 5 generates elastic force acting on the contact body 4 to restrict the movement of the first and second connection members 11 and 21. Therefore, the opening and closing structure 8 is simpler, the occupation of the internal space of the storage box is reduced, and the manufacturing cost is reduced. On the other hand, the first and second connection members 11 and 21 are connected to the first and second housing portions 6 and 7, respectively, and damping can be generated when the first and second housing portions 6 and 7 are opened or closed. Meanwhile, a first region 511, a second region 512, and a third region 513 are provided on the contact cambered surface 51, and the second region 512 is at a high point of the contact cambered surface 51 with respect to the first region 511 and the third region 513 in the axial direction of the rotating shaft 3. When the user closes the first shell portion 6 and the second shell portion 7, the contact body 4 sequentially slides through the first region 511, the second region 512 and the third region 513, so that the hands of the user feel obvious stress changes, and the use experience of the user is improved. Further, the first region 511 and the third region 513 are both located at a low point of the contact cambered surface 51. Thus, the contact body 4 quickly slides to the first region 511 or the third region 513 after passing through the second region 512, and the opening and closing speed of the storage case is improved.

Further, the second shell portion 7 has a first through hole 62. The number of the contact bodies 4 and the number of the elastic pieces 5 are two, the second rotating part 2 further comprises two stop pieces 23, the first rotating part 1 further comprises two first rotating plates 12, and the two contact bodies 4 are respectively arranged on the plate surfaces of the two first rotating plates 12 in a protruding mode.

The first through holes 62 are located between the two first rotating plates 12, the two elastic pieces 5 and the two stopping pieces 23 at the same time, the rotating shaft 3 penetrates through the first through holes 62, and two ends of the rotating shaft 3 penetrate through the two first rotating plates 12 respectively to be connected with the first shell 6.

The opening and closing structure 8 has an open state. In the open state, the contact body 4 slides to the first region 511, and the two first rotation plates 12 are respectively abutted with the corresponding two stoppers 23.

Specifically, as shown in fig. 2 and 3, the second rotating portion 2 further includes a set screw 91. The second connection member 21 has a connection hole through which a fixing screw 91 passes to fixedly connect the body 24 with the second shell portion 7. In contrast, the number of the first rotation plates 12 is also two, and the two first rotation plates 12 are provided to the first link 11. Both ends of the rotation shaft 3 also pass through the two second through holes 122 and the two third through holes 221 at the same time.

The number of the stop members 23, the elastic members 5 and the contact body 4 in this embodiment is two, so that the stability of connection between the first shell portion 6 and the second shell portion 7 can be improved and shaking can be avoided when the storage box is opened. On the other hand, the contact body 4 and the elastic member 5 in the present embodiment are respectively located at two ends of the rotating shaft 3. Therefore, the occupation of the opening and closing structure 8 to the inner space of the storage box can be reduced, so that the storage box can accommodate the earphone and the charging module.

In some embodiments, as shown in fig. 2, the first shell portion 6 has a first end face 61 and the second shell portion 7 has a second end face 71. The contact body 4 is located in the third region 513, and the first end surface 61 abuts against the second end surface 71.

It will be readily appreciated that the short sides 232 may engage the locating plate rim 121 when the case is in the open condition, thereby limiting the extent of opening of the case. In contrast, when the contact body 4 is located in the third region 513 in the present embodiment, the movement state of the first and second shell portions 6 and 7 can be restricted by the contact of the first and second end faces 61 and 71. For this reason, the opening and closing structure 8 may not be provided with other limit structures alone. Thereby, the number of parts of the opening and closing structure 8 is further reduced.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, and various modifications and variations may be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
