DETAILED DESCRIPTION

[0050] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of this application can be combined with each other. In the embodiments of this application, "mm" refers to the international unit millimeter. "Top", "bottom", orientation or position relationship is based on the attached Fig.17 The orientation or position relationship shown, specifically, Fig.17 The upper part is the "top" and the lower part is the "bottom". It should be understood that these directional terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0051] See also Figures 8 to 16 , an embodiment of the present application provides a rotating mechanism, which includes a connecting plate 12, a mounting seat 22, and a rotating shaft 30. The connecting plate 12 has a first position and a second position. The mounting seat 22 includes a seat body 221 and protrusions 222 extending along both sides of the seat body 221. The seat body 221 is formed with a second notch 221a, and the second notch 221a is located between the two protrusions 222. The protrusion 222 is formed with a receiving groove 222a. The receiving groove 222a is open to the outside of the seat body 221. That is, the receiving groove 222a is open away from the first position. When the connecting plate 12 is in the first position, part of the connecting plate 12 is located on the inner side of the seat body 221 (see Fig.18That is, the connecting plate 12 is located outside the second notch 221a, and part of the connecting plate 12 does not close the second notch 221a. When the connecting plate 12 is located at the second position, part of the connecting plate 12 is located inside the second notch 221a to close the second notch 221a (see Figure 8 The rotating shaft 30 extends into the receiving groove 222a through the connecting plate 12 and the seat body 221, so that the connecting plate 12 can switch between the first position and the second position.

[0052] The connecting plate 12 rotates around the axis of the rotating shaft 30 relative to the mounting seat 22. Thus, the connecting plate 12 rotates around the axis of the rotating shaft 30 in a first direction, and the connecting plate 12 can be located at a first position (see Fig.18 ); The connecting plate 12 can also rotate along the second direction around the axis of the rotating shaft 30, at this time, the connecting plate 12 is located in the second position (see Fig. 9 The mounting seat can be arranged on the housing, and the housing can be a box body of a storage box, a plate body, or a housing of other devices that need to be rotatably connected. The housing forms a first notch, and the mounting seat is arranged at the first notch of the housing, with the open part of the receiving groove 222a facing the side wall of the housing (see Figure 4 ), in this way, the receiving groove 222a and the side wall of the shell can be used to form a first shaft hole. Since the rotating shaft 30 extends into the receiving groove 222a through the connecting plate 12 and the seat body 221, that is, the rotating shaft 30 is passed through the connecting plate 12 and the seat body 221 and is arranged in the first shaft hole 22a (taking the shell as a box body of a storage box as an example), that is, the rotating shaft 30 is passed through the connecting plate 12 and the seat body 221 located in the first notch 21b and is arranged in the first shaft hole 22a, and the seat body 221 and the protruding portion 222 are used to bear the bending moment and torque together. In this way, under the condition that the mounting seat 22 can withstand sufficiently large bending moment and torque, the protruding portion 222 is used to withstand most of the force from the rotating shaft 30, and the size of the part where the seat body 221 is connected to the rotating shaft 30 can be made small, that is, the size of the part where the seat body 221 is located in the first notch 21b can be made as small as possible. When the connecting plate 12 is in the second position, the user observes the connecting plate 12 and the mounting seat 22 from the outside of the seat body 221. Since the portion of the seat body 221 located in the first notch 21b is relatively small, the seat body 221 and the connecting plate 12 can present a visual effect of an integrated structure, thereby avoiding the situation where the portion connecting the seat body 221 and the rotating shaft 30 has to be enlarged in order to ensure that the mounting seat 22 is effectively stressed, resulting in the connecting plate 12 and the seat body 221 being visually segmented. In terms of industrial design, the structure of the embodiment of the present application can greatly improve the aesthetics, increase the texture and product expression.

[0053] In a specific embodiment, the rotating mechanism of the embodiment of the present application is shown in FIG. Figures 8 to 16, the seat body 221 includes a support rib 2211 and a connecting rib 2212. The connecting plate 12 includes a first plate body 121 and a second plate body 122. The support rib 2211 extends along the axial direction of the rotating shaft 30. In other words, the support rib 2211 extends along the axial direction parallel to the rotating shaft 30. Further, the end surface of the support rib 2211 facing the outer side of the mounting seat 22 is formed with a step surface 2211a. The step surface 2211a is supported on the bottom wall of the first notch of the shell. The two connecting ribs 2212 are respectively connected to the two ends of the support rib 2211. The support rib 2211 and the two connecting ribs 2212 are jointly arranged to form the second notch 221a. The protrusion 222 is connected to the connecting rib 2212, and the rotating shaft 30 passes through the connecting rib 2212 and extends into the accommodating groove 222a. The first plate body 121 includes a middle portion 1211 and an outer edge portion 1212. The outer edge portion 1212 is arranged around the periphery of the middle portion 1211. The outer edge portion 1212 is formed with avoidance grooves 121a on opposite sides along the axial direction of the rotating shaft 30. When the connecting plate 12 is located in the second position, part of the connecting rib 2212 is located in the avoidance groove 121a, and the outer edge portion 1212, the supporting rib 2211 and the two connecting ribs 2212 are jointly arranged to form an annular structure, and the middle portion 1211 is located in the annular structure. In this way, when the user observes the connecting plate 12 and the mounting seat 22 from the outside of the mounting seat 22, the outer edge portion 1212, the supporting rib 2211 and the two connecting ribs 2212 present a visual effect of an integrated structure. The second plate body 122 is connected to the inner end face of the first plate body 121. That is, the second plate body 122 is connected to the end face of the first plate body 121 close to the inner side of the seat body 221. Specifically, the second plate body 122 includes a connecting portion 1221 and an extension portion 1222 extending from the connecting portion 1221 in a direction away from the mounting seat 22. The connecting portion 1221 is connected to the inner end surface of the first plate body 121. The extension portion 1222 is used as a force-bearing structure to be connected to an external structure. The second plate body 122 is formed with a second shaft hole 1221a arranged along the axial direction of the rotating shaft 30, and the rotating shaft 30 is penetrated in the second shaft hole 1221a. In this way, the first plate body 121 can cover the second plate body 122 and the rotating shaft 30 by using the second plate body 122 as the main force-bearing structure. Specifically, the second shaft hole 1221a can be formed on the connecting portion 1221. The support rib 2211 and the two connecting ribs 2212 are connected to the first notch of the shell. Part of the connecting rib 2212, part of the supporting rib 2211 and the first plate body 121 jointly close the first notch 21b. That is, when the rotating mechanism is arranged on the housing, the connecting rib 2212 and the supporting rib 2211 are both located in the first notch of the housing, and together with the connecting plate 12, they seal the first notch of the housing. In this way, the side wall of the first notch of the housing is used to limit the seat body 221 from moving along the axis of the rotating shaft 30, and the bottom wall of the first notch of the housing is used to limit the seat body 221 from moving downward, thereby improving the structural stability of the mounting seat 22.

[0054] In one embodiment, the rotating mechanism provided in the embodiment of the present application is used for a storage box. For details, see Figure 1 to Figure 7 The present application provides a storage box, which includes a box cover 10, a box body 20 and a rotating shaft 30. The box cover 10 includes a cover shell 11 and a connecting plate 12 connected to the cover shell 11. The box body 20 includes a shell 21 and a mounting seat 22. The shell 21 includes a receiving space 21a with a top opening and a first notch 21b formed on the side wall of the shell 21. The receiving space 21a is connected to the first notch 21b. The mounting seat 22 includes a seat body 221 and protrusions 222 extending along both sides of the seat body 221 (see Figure 8 to Figure 10 The seat body 221 is formed with a second notch 221a (see Fig.12 The protruding portion 222 is formed with a receiving groove 222a (see Fig.12 The mounting seat 22 is connected to the first notch 21b. The protrusion 222 is located in the accommodation space 21a. The accommodation groove 222a is open to the side wall of the housing 21. The accommodation groove 222a and the side wall of the housing 21 are jointly surrounded to form a first shaft hole 22a (see Figure 4 The rotating shaft 30 extends into the first shaft hole 22a through the connecting plate 12 and the seat body 221, so that the cover shell 11 can switch between the open position and the closed position covering the shell 21. When the cover shell 11 is in the closed position, part of the connecting plate 12 is located in the second notch 221a to close the second notch 221a, and part of the seat body 221 and part of the connecting plate 12 jointly close the first notch 21b.

[0055] The box cover 10 rotates relative to the box body 20 around the axis of the rotating shaft 30, so that the box cover 10 rotates along the first direction around the axis of the rotating shaft 30, and the cover shell 11 can be located in the open position. At this time, objects can be placed in the accommodating space 21a through the top opening of the accommodating space 21a; the box cover 10 can also rotate along the second direction around the axis of the rotating shaft 30, at this time, the cover shell 11 is located in the closed position, and the cover shell 11 covers the shell 21. The part of the seat body 221 and the part of the connecting plate 12 jointly close the first notch 21b, that is, the part of the seat body 221 and the part of the connecting plate 12 are both located in the first notch 21b, and the part of the connecting plate 12 located in the first notch 21b is also located in the second notch 221a and closes the second notch 221a. In the process of the box cover 10 rotating relative to the box body 20, the part of the connecting plate 12 located in the second notch 221a avoids the second notch 221a and the first notch 21b and moves toward the inside of the shell 21, while the part of the seat body 221 located in the first notch 21b is fixed. The first shaft hole 22a is formed by the receiving groove 222a and the side wall of the housing 21, and the rotating shaft 30 is inserted into the first shaft hole 22a through the connecting plate 12 and the seat body 221, that is, the rotating shaft 30 is inserted into the first shaft hole 22a through the connecting plate 12 and the seat body 221 located in the first notch 21b, and the seat body 221 and the protruding portion 222 are used to bear the bending moment and torque together. In this way, under the condition that the mounting seat 22 can withstand sufficiently large bending moment and torque, the protruding portion 222 is used to withstand most of the force from the rotating shaft 30, and the size of the portion where the seat body 221 is connected to the rotating shaft 30 can be made small, that is, the size of the portion where the seat body 221 is located in the first notch 21b can be made as small as possible. When the cover shell 11 is in the closed position, the user observes the box cover 10 and the box body 20 from the side of the shell 21 away from the protrusion 222. Most of the structure of the mounting seat 22 is hidden in the shell 21. Since the portion of the seat 221 located in the first notch 21b is relatively small, the seat 221 and the connecting plate 12 can also present a visual effect of an integrated structure, avoiding the situation where the portion connecting the seat 221 and the shaft 30 has to be enlarged in order to ensure that the mounting seat 22 is effectively stressed, resulting in the visual segmentation of the connecting plate 12 and the seat 221. In terms of industrial design, the structure of the embodiment of the present application can greatly improve the aesthetics, texture and product expression. In addition, the portion of the seat 221 located in the first notch 21b can limit the movement of the mounting seat 22 along the axis of the shaft 30. Since the accommodating groove 222a is open to the side wall of the shell 21, the accommodating groove 222a and the side wall of the shell 21 are jointly arranged to form the first axial hole 22a. In this way, the protrusion 222 can be close to the side wall of the shell 21, reducing the distance between the protrusion 222 and the side wall of the shell 21, avoiding the mounting seat 22 from occupying too much space in the box body 20, and making the structure of the box body 20 more compact.

[0056] It should be noted that the second direction is opposite to the first direction. Exemplarily, if the first direction is clockwise, the second direction is counterclockwise. Of course, if the first direction is counterclockwise, the second direction is clockwise. The inner side of the seat 221 refers to the side of the shell 21 close to the accommodating space 21a. Relatively speaking, the outer side of the seat 221 refers to the side of the shell 21 away from the accommodating space 21a. In other words, the inner side of the seat 221 and the outer side of the seat 221 refer to the opposite sides of the seat 221. For the convenience of the description of this application, the embodiment of the present application defines the inner side of the seat 221 and the outer side of the seat 221.

[0057] It can be understood that when the rotating mechanism provided in the embodiment of the present application is used for a storage box, the connecting plate 12 in the rotating mechanism is in a first position, that is, the cover shell 11 of the storage box is in an open position, and the connecting plate 12 in the rotating mechanism is in a second position, that is, the cover shell 11 of the storage box is in a closed position.

[0058] In one embodiment, see Figure 1 to Figure 7 The storage box is an earphone charging box, and the earphones are stored in the storage space 21a. The earphone charging box can charge the earphones. Since the box body 20 not only needs to accommodate the earphones, but also needs to be provided with a power supply, a circuit board, a charging contact sheet, and other structures for charging the earphones, there are many parts in the box body 20, so that the space in the box body 20 for accommodating the mounting seat 22 is relatively small. The mounting seat 22 of the embodiment of the present application has a compact structure and is suitable for the narrow space in the shell 21 of the earphone charging box.

[0059] The earphone charging box is used to charge the matching earphones. Specifically, the earphone charging box has a power source for storing electric energy inside. When the earphones are placed in the earphone charging box, the power source for storing electric energy can charge the earphones. The earphones in the embodiments of the present application can be paired and connected with smart terminals such as mobile phones and tablets. When the user uses the smart terminal, the audio can be automatically switched to the earphones. The earphones can be Bluetooth earphones, infrared earphones, etc., which are not limited here.

[0060] In one embodiment, see Figure 8 to Figure 14The seat body 221 includes a support rib 2211 and a connecting rib 2212. The support rib 2211 extends along the axial direction of the rotating shaft 30. The end surface of the support rib 2211 facing the outer side of the shell 21 is formed with a step surface 2211a, and the step surface 2211a is supported on the bottom wall of the first notch 21b. The two connecting ribs 2212 are respectively connected to the two ends of the support rib 2211. The support rib 2211 and the two connecting ribs 2212 are jointly arranged to form the second notch 221a. The protrusion 222 is connected to the connecting rib 2212, and the rotating shaft 30 passes through the connecting rib 2212 and extends into the first shaft hole 22a, and the support rib 2211 and the two connecting ribs 2212 are connected to the first notch 21b. In other words, part of the connecting rib 2212 and part of the support rib 2211 are both located in the first notch 21b, and together with part of the connecting plate 12, the first notch 21b is closed. In this way, the side wall of the first notch 21 b is used to limit the seat body 221 from moving along the axial direction of the rotating shaft 30 , and the bottom wall of the first notch 21 b is used to limit the seat body 221 from moving downward, thereby improving the structural stability of the mounting seat 22 .

[0061] In some embodiments, see Figure 1 , Figure 7 , Fig. 9 and Fig.12 , connecting rib 2212( Figure 7 ) is located at the first notch 21b (see Fig.12 ) along the axis of rotation 30 (see Fig. 9 ) is A, where 0.5mm≤A≤1.2mm. For example, A can be 0.5mm, 0.8mm, 1.0mm, 1.1mm or 1.2mm, etc. In some embodiments, the length of the first notch 21b along the axial direction of the rotating shaft 30 is B, where 1 / 25≤A / B≤1 / 15. For example, the ratio of A to B can be 1:25, 1:24, 1:23, 1:21, 1:20, 1:18, 1:15, etc. In this way, under the condition of ensuring the force-bearing capacity of the portion of the seat body 221 located in the first notch 21b, the length of the portion of the connecting rib 2212 located in the first notch 21b along the axial direction of the rotating shaft 30 is small enough, so as to achieve a visual effect that the portion of the connecting rib 2212 located in the first notch 21b and the connecting plate 12 are almost completely integrated, thereby further improving the aesthetics.

[0062] In one embodiment, see Figure 8 to Figure 11 as well as Figure 15-16, the connecting plate 12 includes a first plate body 121 and a second plate body 122. The first plate body 121 is respectively formed with avoidance grooves 121a on opposite sides along the axial direction of the rotating shaft 30. When the cover shell 11 is in the closed position, part of the connecting rib 2212 is located in the avoidance groove 121a, and part of the connecting rib 2212, part of the supporting rib 2211 and the first plate body 121 jointly close the first notch 21b. The second plate body 122 includes a connecting portion 1221 and an extending portion 1222 extending from the connecting portion 1221 toward the box cover 10. The connecting portion 1221 is connected to a side of the first plate body 121 close to the accommodating space 21a. The extending portion 1222 is connected to the cover shell 11. The connecting portion 1221 is formed with a second shaft hole 1221a arranged along the axial direction of the rotating shaft 30, and the rotating shaft 30 is penetrated in the second shaft hole 1221a.

[0063] The rotating shaft 30 is passed through the second shaft hole 1221a and the first shaft hole 22a so that the rotating shaft 30 connects the second plate body 122 and the protrusion 222. In this way, the bending moment and torque are borne by the second plate body 122, that is, the second plate body 122 is the main force-bearing structure. The extension part 1222 is connected to the cover shell 11 to enhance the force-bearing capacity of the second plate body 122. Since the connecting part 1221 is connected to the side of the first plate body 121 close to the accommodating space 21a, the first plate body 121 can cover the rotating shaft 30, the connecting part 1221 and other structures of the seat body 221, so that the user cannot see the internal structure of the box body 20 from the side of the first plate body 121 away from the accommodating space 21a, further improving the aesthetics of the storage box.

[0064] Specifically, the extension portion 1222 is connected to the cover shell 11 by welding the extension portion 1222 and the cover shell 11, or the extension portion 1222 and the cover shell 11 are connected by a connecting member, and the connecting member can be a bolt (see Fig.17 and Fig.18 ). This makes it easy to install and remove the connecting plate 12 from the cover shell 11.

[0065] In one embodiment, see Fig. 9 , Fig.10 and Fig.15 , the first plate body 121 includes a middle portion 1211 and an outer edge portion 1212. The outer edge portion 1212 is arranged around the outer periphery of the middle portion 1211. The avoidance groove 121a is formed on the outer edge portion 1212. The outer edge portion 1212, the support rib 2211 and the two connecting ribs 2212 are together arranged to form an annular structure. The middle portion 1211 is located in the annular structure. In this way, when the cover shell 11 is in the closed position, the user observes the box cover 10 and the box body 20 from the side of the shell 21 away from the accommodating space 21a, and the outer edge portion 1212, the support rib 2211 and the two connecting ribs 2212 present a visual effect of an integrated structure.

[0066] Specifically, the annular structure may be circular, elliptical or polygonal, etc. The polygonal shape may be a quadrilateral, a pentagon, a hexagon, etc. In a specific embodiment, the annular structure is a rectangle.

[0067] For further information, see Fig. 9 and Fig.10 On the plane where the first plate body 121 is located, the projection pattern formed by the support rib 2211 and the two connecting ribs 2212 is axially symmetrical with the projection pattern of the outer edge portion 1212. In this way, the aesthetic feeling is further improved.

[0068] In some embodiments, see Fig. 9 , Fig.10 and Fig.15 The contact seam between the support rib 2211 and the outer edge 1212 is flush with the contact seam between the cover shell 11 and the housing 21. In this way, the visual effect of the misalignment between the support rib 2211 and the outer edge 1212 and the cover shell 11 and the housing 21 is avoided, further improving the aesthetics.

[0069] In some embodiments, see Fig. 9 , Fig.10 and Fig.15 The end surface of the middle part 1211 away from the accommodation space 21a is formed with a concave platform. The storage box includes a panel arranged on the concave platform. The panel can be a display screen or an information sticker. The information sticker refers to a sticker containing warning information, product information or other information. With such a design, the end surface of the middle part 1211 away from the accommodation space 21a can be fully utilized to transmit information.

[0070] Specifically, the concave platform can be circular, elliptical or polygonal, etc. The polygonal shape can be quadrilateral, pentagon, hexagon, etc. In a specific embodiment, the concave platform is rectangular.

[0071] In some embodiments, see Fig. 9 , Fig.10 and Fig.15, the end face of the outer edge portion 1212 away from the accommodating space 21a, the end face of the support rib 2211 away from the accommodating space 21a, and the end faces of the two connecting ribs 2212 away from the accommodating space 21a are in the first color. In this way, the outer edge portion 1212, the support rib 2211, and the two connecting ribs 2212 present an integrated structure. Further, the end face of the middle portion 1211 away from the accommodating space 21a is in the second color, the first color and the second color, in this way, by utilizing the difference between the first color and the second color, the outer edge portion 1212, the support rib 2211, and the two connecting ribs 2212 present a visual effect of an integrated structure. Of course, the first color can also be the same as the second color. In this way, the middle portion 1211, the outer edge portion 1212, the support rib 2211, and the two connecting ribs 2212 jointly present a visual effect of an integrated structure. Exemplarily, the first color can be gold and the second color is silver.

[0072] In some embodiments, see Fig. 9 , Fig.10 and Fig.15 , the end surface of the outer edge portion 1212 away from the accommodating space 21a, the end surface of the support rib 2211 away from the accommodating space 21a, and the end surface of the two connecting ribs 2212 away from the accommodating space 21a present a first texture. In this way, the outer edge portion 1212, the support rib 2211 and the two connecting ribs 2212 present an integrated structure. Further, the end surface of the middle portion 1211 away from the accommodating space 21a presents a second texture, the first texture and the second texture, so that the difference between the first texture and the second texture is used to further provide the outer edge portion 1212, the support rib 2211 and the two connecting ribs 2212 present a visual effect of an integrated structure. Of course, the first texture can also be the same as the second texture. In this way, the middle portion 1211, the outer edge portion 1212, the support rib 2211 and the two connecting ribs 2212 present a visual effect of an integrated structure. Exemplarily, the first texture can be a twill, a well pattern, a diamond pattern, etc. The second pattern may also be a twill pattern, a cross pattern, a diamond pattern, or the like.

[0073] In some embodiments, see Figure 4 and Figure 5 The rotating shaft 30 can be a long shaft, which passes through the first shaft hole 22a, the second shaft hole 1221a and the seat body 221. The rotating shaft 30 can also be two short shafts, one of which passes through a first shaft hole 22a and one side of the seat body 221 and extends into the second shaft hole 1221a, and the other short shaft passes through another first shaft hole 22a and the other side of the seat body 221 and extends into the second shaft hole 1221a. In all of the above, the connecting plate 12 and the mounting seat 22 can be connected by the rotating shaft 30.

[0074] In other embodiments, two short shafts may also be connected to two opposite sides of the connecting plate 12 , and the two short shafts extend into the two first shaft holes 22 a respectively, so that the connecting plate 12 is pivotally connected to the mounting seat 22 .

[0075] In one embodiment, see Fig.11 and 16 The end surface of the first plate body 121 facing the accommodation space 21a is formed with a groove 121b, and the groove 121b extends along the axial direction of the rotating shaft 30, and a part of the rotating shaft 30 is located in the groove 121b. In this way, it is convenient to reduce the distance between the end surface of the first plate body 121 facing the accommodation space 21a and the rotating shaft 30, so that the structure of the mounting seat 22 is more compact. In addition, during the rotation process of the connecting plate 12, the cooperation between the groove 121b and the rotating shaft 30 can also play a role in rotation guidance, so that the rotation process of the connecting plate 12 is more stable.

[0076] Specifically, the groove wall surface of the groove 121b is matched with the outer surface of the rotating shaft 30. In other words, the rotating shaft 30 is a cylinder, and the groove wall surface of the groove 121b is a curved surface matched with the outer surface of the rotating shaft 30.

[0077] In one embodiment, see Figure 13 to Figure 18 The second plate body 122 includes a boss 123 extending from the connecting portion 1221 toward the seat body 221. The seat body 221 includes a top plate 2213 connected to the top end of the connecting rib 2212. The support rib 2211 and the top plate 2213 jointly define a rotation space 22b. Along the height direction of the seat body 221, the rotation shaft 30 is located between the top plate 2213 and the support rib 2211. The boss 123 can rotate around the axis of the rotation shaft 30 in the rotation space 22b. The boss 123 abuts against the top plate 2213 to define the open position of the cover shell 11, and the boss 123 abuts against the support rib 2211 to define the closed position of the cover shell 11. The support rib 2211 stops the boss 123 to define the closed position of the cover shell 11, and the top plate 2213 stops the boss 123 to define the open position of the cover shell 11. In this way, not only can the cover shell 11 be stably maintained in the closed position and the open position, but also the opening angle of the cover shell 11 can be limited. For example, the opening angle of the cover shell 11 is limited by controlling the inclination angle of the top plate 2213 or providing recessed areas 2214a of different depths on the top plate 2213. For example, the opening angle can be 80°, 90°, 100°, etc., so as to facilitate taking or placing items from the accommodating space 21a.

[0078] In one embodiment, see Fig.16 The dimension of the connecting portion 1221 along the axis direction of the rotating shaft 30 is smaller than the dimension of the first plate body 121 along the axis direction of the rotating shaft 30. With such a design, it is convenient to cover the connecting portion 1221 with the first plate body 121.

[0079] In one embodiment, see Fig.16 The dimension of the boss 123 along the axis of the rotating shaft 30 is smaller than the dimension of the first plate 121 along the axis of the rotating shaft 30 , so that the boss 123 can rotate in the rotating space 22 b and other structures of the seat body 221 can be prevented from interfering with the movement of the boss 123 .

[0080] In one embodiment, see Figure 12 to Figure 14 The top plate 2213 is formed with an opening groove 2213a which opens toward the connecting portion 1221. When the cover shell 11 is in the closed position, part of the connecting portion 1221 is located in the opening groove 2213a. The opening groove 2213a provides an escape space for the connecting portion 1221 to prevent the connecting portion 1221 from interfering with the top plate 2213 during the rotation process, so that the connecting plate 12 has a larger rotation range.

[0081] In one embodiment, see Figure 12 to Figure 14 The mounting seat 22 is an integrally formed structure. In this way, the structural strength between the various components of the mounting seat 22 is enhanced, and the process flow is saved. Of course, the mounting seat 22 can also be a split structure, and the various components are connected, for example, by welding.

[0082] In one embodiment, see Figure 15-16 The connecting plate 12 is an integrally formed structure. In this way, the structural strength between the components of the connecting plate 12 is strengthened, and the process flow is saved. Of course, the connecting plate 12 can also be a split structure, and the components are connected, for example, by welding.

[0083] The mounting seat 22 and the connecting plate 12 provided in the embodiment of the present application can be made of metal materials to increase the texture, further improve the aesthetics, and increase the product expression. Of course, the mounting seat 22 and the connecting plate 12 can also be made of plastic to reduce the weight. The embodiment of the present application does not limit the materials of the mounting seat 22 and the connecting plate 12.

[0084] In one embodiment, see Figure 1 and Figure 2 When the cover shell 11 is in the closed position, the outer surface of the shell 21, the surface of the seat body 221 in the first notch 21b, and the surface of the connecting plate 12 together form a smooth surface. In other words, the seat body 221 in the first notch 21b and the connecting plate 12 in the first notch 21b will not protrude or be lower than the outer surface of the shell 21. Such a design can not only improve the aesthetics, but also facilitate the user to grasp the shell 21 without feeling sharp corners or protruding structures, and has a better hand feel.

[0085] In one embodiment, see Figure 4-5 as well as Figures 17 to 20, the storage box includes an elastic member 40, the cover shell 11 has a critical position, the critical position is located between the closed position and the open position, and the elastic member 40 is loaded between the mounting seat 22 and the connecting plate 12. In other words, for the elastic member 40, the mounting seat 22 and the connecting plate 12 are both loads of the elastic member 40. When the cover shell 11 is located at the critical position, the torque applied by the elastic member 40 to the box cover 10 is zero. When the cover shell 11 deviates to either side of the critical position along the rotation direction, the elastic member 40 applies a driving torque to the box cover 10 to drive the cover shell 11 to move to the closed position or the open position.

[0086] It should be noted that the above “when the cover shell 11 deviates to any side of the critical position along the rotation direction, the elastic member 40 applies a driving torque to the box cover 10 to drive the cover shell 11 to move to the closed position or the open position” includes the following two situations: the first situation: when the cover shell 11 deviates from the critical position and is located on the first side of the critical position along the rotation direction, the elastic member 40 drives the cover shell 11 to move to the open position. The second situation: when the cover shell 11 deviates from the critical position and is located on the second side of the critical position along the rotation direction, the elastic member 40 drives the cover shell 11 to move to the closed position.

[0087] Specifically, see Fig.19 The elastic member 40 exerts a force F1 on the box cover 10, and the force F1 generates an axis around the rotation axis 30 (simplified as Fig.19 The first torque W1 is the driving torque mentioned above. The cover shell 11 moves to the closed position and remains in the closed position under the action of the first torque W1. That is to say, in the absence of external force or the external force on the box cover 10 is not sufficient to overcome the resistance formed by the first torque W1, the cover shell 11 will not deviate from the current closed position.

[0088] See also Fig. 20 The elastic member 40 exerts a force F2 on the box cover 10, and the force F2 generates an axis around the rotation axis 30 (simplified as Fig. 20 The second torque W2 is the driving torque mentioned above, wherein the first torque W1 is opposite to the second torque W2. The cover shell 11 moves to the open position and remains at the current open position under the action of the second torque W2. That is to say, in the absence of external force or the external force on the box cover 10 is insufficient to overcome the resistance formed by the second torque W2, the cover shell 11 will not deviate from the current open position.

[0089] When the cover shell 11 needs to switch from the closed position to the open position, the user can slowly turn the box cover 10. At this time, the force applied by the user needs to be able to overcome the resistance generated by the first torque W1, that is, the first torque W1 at this time is the resistance torque. When the rotation angle of the cover shell 11 can make the cover shell 11 pass the above-mentioned critical position, the elastic member 40 applies a second torque W2 in the opposite direction to the box cover 10. The direction of the second torque W2 is the same as the rotation direction. At this time, the second torque W2 is the driving torque. Even if the user lets go, the cover shell 11 can automatically rotate under the action of the elastic member 40 until it reaches the open position, and stably remain in the open position under the action of the second torque W2.

[0090] When the cover shell 11 needs to switch from the open position to the closed position, the user can slowly rotate the box cover 10 in the opposite direction. At this time, the force applied by the user needs to be able to overcome the resistance generated by the second torque W2, that is, the second torque W2 at this time is the resistance torque. When the rotation angle of the cover shell 11 can make the box cover 10 pass the above-mentioned critical position, the elastic member 40 applies the first torque W1 in the opposite direction to the box cover 10. Even if the user lets go, the cover shell 11 can automatically continue to rotate to the closed position under the action of the elastic member 40, and stably remain in the closed position under the action of the first torque W1.

[0091] That is to say, within a certain rotation range, the cover shell 11 has the functions of automatic closing and automatic opening, and both the closing process and the opening process have a damping feel, which is conducive to improving the user experience.

[0092] In one embodiment, see Fig.21 , the elastic member 40 includes at least one torsion spring 40'. The torsion spring 40' includes a first leg 41, a second leg 42 and a spiral body 43. The first leg 41 and the second leg 42 are connected to opposite axial sides of the spiral body 43. The first leg 41 is connected to the seat body 221, and the second leg 42 is connected to the connecting plate 12 to drive the cover shell 11 to rotate around the axis of the rotating shaft 30. In other words, the second leg 42 of the torsion spring 40' can drive the cover shell 11 to rotate around the axis of the rotating shaft 30 in a first direction, and can also drive the cover shell 11 to rotate around the axis of the rotating shaft 30 in a second direction. The first direction is opposite to the second direction. The angle between the axis of the spiral body 43 and the axis of the rotating shaft 30 is in the range of 45° to 90°. In this way, the space occupied by the torsion spring 40' along the axial direction perpendicular to the rotating shaft 30 can be reduced, so that the structure of the storage box is compact.

[0093] Specifically, the spiral body 43 is suspended, that is, the spiral body 43 will move along with the second leg 42 .

[0094] It is understandable that the torsion spring 40' can form the above-mentioned first moment W1 in a squeezed state, or can form the above-mentioned first moment W1 in a stretched state. Similarly, the torsion spring 40' can form the above-mentioned second moment W2 in a squeezed state, or can form the above-mentioned second moment W2 in a stretched state. No limitation is made here.

[0095] When the cover shell 11 rotates, the distance between the end of the first leg 41 and the end of the second leg 42 will change, which will cause the pitch of the spiral body 43 to change. In other words, the spiral body 43 produces elastic deformation along its axial direction, so the spiral body 43 has a rebound force along its axial direction. The rebound force acts on the box cover 10 to form the above-mentioned force F1 and force F2. Since the above-mentioned force F1 and force F2 are roughly along the axial direction of the spiral body 43, the direction of the force is relatively certain. Therefore, in the design process of the torsion spring 40', the diameter, material, pitch size, etc. of the spiral body 43 can be conveniently designed.

[0096] In a specific embodiment, the axis of the spiral body 43 is perpendicular to the axis of the rotating shaft 30. In other words, the angle between the axis of the spiral body 43 and the axis of the rotating shaft 30 is 90°. Since the torsion spring 40' relies on the force formed by the axial elastic deformation of the spiral body 43, even if the maximum distance between the end of the first leg 41 and the end of the second leg 42 is designed to be relatively small, the torsion spring 40' can still exert a large elastic force on the box cover 10. Therefore, the torsion spring 40' is Fig.17 The dimensions in the height direction (up and down direction) and the width direction (left and right direction) are relatively small, so that the storage box structure can be compact.

[0097] It is understandable that the number of torsion springs 40' can be one or more, wherein more includes two or more. It should be noted that in the embodiment with multiple torsion springs 40', the multiple torsion springs 40' can be spaced apart from each other and not interfere with each other, or can be connected to each other.

[0098] It should be noted that in the embodiment with only one torsion spring 40', the first leg 41 and the second leg 42 will both form a force component along the axis of the rotating shaft 30, and the force components of the two are in the same direction. This force component will force the box cover 10 to move along the axis of the rotating shaft 30, causing a shaking and unstable feeling to the user. For this reason, in one embodiment, see Figure 4 , Figure 5 as well as Fig.21, the number of torsion springs 40' is two, the ends of the first legs 41 of the two torsion springs 40' are fixedly connected, and the axes of the spiral bodies 43 of the two torsion springs 40' are parallel. That is to say, the two torsion springs 40' form a double torsion spring 40' structure. On the one hand, the double torsion spring 40' has high structural strength, large torsion force, good stability, is not easy to deform when subjected to large force, has a long service life, and can improve the reliability and durability of the storage box. On the other hand, the two torsion springs 40' have opposite forces along the axis direction of the rotating shaft 30 and can offset each other, so the box cover 10 can be centered at the middle position along the axis of the rotating shaft 30. Specifically, due to manufacturing errors, assembly errors, etc., there will be a certain axial gap between the box cover 10 and the mounting seat 22 along the axis direction of the rotating shaft 30. The axial gap must be able to ensure that the box cover 10 and the mounting seat 22 can be assembled normally, and cannot cause a large dry friction between the box cover 10 and the mounting seat 22. Due to the existence of the axial gap, the box cover 10 has the possibility of axial movement. Under the action of the two torsion springs 40', when the box cover 10 is located in the middle position, the axial forces of the two torsion springs 40' are balanced. Fig.21 When the left side of the box moves a little, the torsion spring 40' on the right will force the box cover 10 to move to the right. Fig.21 When the box cover 10 moves a little on the right side, the torsion spring 40' on the left side will force the box cover 10 to move to the left, and so on, the box cover 10 is stabilized at the middle equilibrium position. In this way, even if the box cover 10 has a large axial gap on both sides along the axial direction, the box cover 10 will not move along the axial direction, which can reduce the manufacturing accuracy and assembly accuracy requirements of the box cover 10 and the mounting seat 22, which is conducive to reducing production costs.

[0099] Specifically, in a specific embodiment of the present application, please refer again to Fig.21 The first leg 41 and the second leg 42 are both bent structures, and the two torsion springs 40' roughly form a regular hexagonal structure.

[0100] In one embodiment, see Fig.11 and Fig.16 , the connecting plate 12 is provided with insertion holes 12a on opposite sides along the axis direction of the rotating shaft 30, the end of the second leg 42 of one torsion spring 40' is located in one of the insertion holes 12a, and the end of the second leg 42 of the other torsion spring 40' is located in the other insertion hole 12a. When the box cover 10 rotates around the axis of the rotating shaft 30, the end of the second leg 42 of the torsion spring 40' can rotate in the insertion hole 12a to improve the force condition of the torsion spring 40' itself.

[0101] In a specific embodiment, see Fig.11 and Fig.16The two plug holes 12 a are located on the same straight line, and the line connecting the two plug holes 12 a is parallel to the axis of the rotating shaft 30 .

[0102] In one embodiment, see Fig.11 and Fig.16 The insertion holes 12a are formed on opposite sides of the boss 123 along the axis of the rotating shaft 30. The size of the boss 123 along the axis of the rotating shaft 30 is smaller than the size of the first plate 121 along the axis of the rotating shaft 30. In this way, the distance between the ends of the second legs 42 of the two torsion springs 40' is small, which facilitates the installation of the torsion springs 40'. For further information, please refer to Fig.12 and Fig.13 The support rib 2211 is provided with an avoidance notch 2211b at the position where the support rib 2211 is used to abut against the boss 123. When the cover shell 11 is in the closed position, part of the boss 123 is located in the avoidance notch 2211b. In this way, not only can the boss 123 and the support rib 2211 be effectively matched, but also the thickness of the boss 123 along the axis direction perpendicular to the shaft 30 can be thicker, which is convenient for setting the plug hole 12a on the boss 123 and avoiding the hole wall of the plug hole 12a being too thin.

[0103] In one embodiment, see Fig.12 and Fig.13 The seat body 221 includes a bottom plate 2214 connected to the bottom end of the connecting rib 2212. A recessed area 2214a is formed on the top surface of the bottom plate 2214. The seat body 221 also includes a baffle 2215 located on the top side of the recessed area 2214a. The baffle 2215 and the surface of the recessed area 2214a together define a limiting groove, and the first leg 41 of the torsion spring 40' is movably disposed in the limiting groove. That is, in this embodiment, during assembly, it is only necessary to insert the first leg 41 of the torsion spring 40' into the limiting groove, and the baffle 2215 can prevent the first leg 41 from detaching from the bottom plate 2214 from the top side of the recessed area 2214a.

[0104] In one embodiment, see Figure 7 The inner surface of the housing 21 is provided with a plug-in slot 20a, and the seat body 221 can be inserted into the plug-in slot 20a from the top opening of the accommodating space 21a, and the seat body 221 is supported on the bottom wall of the plug-in slot 20a. During the assembly process, the seat body 221 can be first inserted downward into the plug-in slot 20a from the top opening of the accommodating space 21a. The plug-in slot 20a can not only limit the downward movement of the seat body 221, but also limit the movement of the seat body 221 along the axis direction of the rotating shaft 30 and the axis direction perpendicular to the rotating shaft 30, that is, limit the movement of the seat body 221 along the downward, front, rear, left and right directions in the figure. In this way, the fixed installation of the seat body 221 can be achieved without using screws, bonding and other fastening methods, and no additional fasteners are required. The fixing method is reliable and saves assembly time.

[0105] In some embodiments, see Figure 3 and Figure 5 The storage box also includes a storage cover 50, which is formed with a storage slot 50a. The storage cover 50 is pressed against the side of the seat 221 facing the box cover 10 to fix the seat 221 in the plug-in slot 20a. After the seat 221 is inserted into the plug-in slot 20a, the storage cover 50 is pressed against the side of the seat 221 facing the box cover 10, and the seat 221 is fixed in the plug-in slot 20a by the storage cover 50, that is, the storage cover 50 can limit the upward movement of the seat 221 to prevent the seat 221 from escaping from the top side of the plug-in slot 20a. When the storage box is an earphone charging box, the earphone is placed in the storage slot 50a.

[0106] In some embodiments, see Figure 7 The box body 20 includes a first convex rib 23 and two second convex ribs 24 protruding from the inner surface of the shell 21. The first convex rib 23 extends in a direction parallel to the axis of the rotating shaft 30, and the two second convex ribs 24 extend from opposite ends of the first convex rib 23 toward the box cover 10, and one end of the second convex rib 24 away from the shell 21 is bent toward the other second convex rib 24. The two second convex ribs 24, the first convex rib 23 and the inner surface of the shell 21 are jointly formed to form the plug-in slot 20a, and the seat body 221 is supported on the first convex rib 23. In this way, the plug-in slot 20a can be manufactured quickly and conveniently.
