In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] Please also read Figures 1 to 6 The earphone charging box provided in the embodiment of the present application is now described. The earphone charging box includes: a seat body 10, a box cover 20 and an elastic member 30.

[0031] Please also read Figure 3 and Figure 4The box cover 20 is connected to the base body 10 for rotation around the first center line a; the elastic member 30 includes a connecting section 31 and two deformation sections 32, the length of the connecting section 31 extends along the direction of the second center line b, the second center line b is parallel to the first center line a, the connecting section 31 is connected to the base body 10 for rotation around the second center line b, the two deformation sections 32 are arranged at intervals along the direction of the second center line b, and one end of the two deformation sections 32 is respectively connected to the opposite ends of the connecting section 31, and the other ends of the two deformation sections 32 are connected to the box cover 20, so that when the box cover 20 rotates around the first center line a, the deformation section 32 is driven to rotate around the second center line b, and the deformation section 32 is elastically deformed; the two deformation sections 32 work together to keep the box cover 20 in a closed state or an open state.

[0032] like Figure 2 As shown, an earphone receiving groove 11 is provided on the side of one side of the seat body 10 , and the wireless earphone can be stored and charged by placing the wireless earphone in the earphone receiving groove 11 .

[0033] The closed state of the box cover 20 means that the box cover 20 covers the side of the base 10 where the earphone receiving slot 11 is provided to cover the earphone receiving slot 11, and the open state of the box cover 20 means that the box cover 20 is open relative to the base 10 to expose the earphone receiving slot 11.

[0034] Optionally, when the box cover 20 is in a closed state, the angle between the box cover 20 and the base 10 is 0°. Figure 1 When the cover 20 is in the open state, the angle between the cover 20 and the base body 10 is 90 °, such as Figure 2 .

[0035] During the rotation of the box cover 20 in a preset direction, after the box cover 20 rotates by a preset angle, the deformation section 32 provides the box cover 20 with an elastic force to continue rotating in the preset direction, thereby maintaining the box cover 20 in a closed state or an open state. For example, when the box cover 20 is in a closed state, the box cover 20 is rotated in a first direction to gradually open the box cover 20. After the box cover 20 rotates by an angle exceeding 45° in the first direction, the deformation section 32 provides the box cover 20 with an elastic force to continue rotating in the first direction. In this way, after the box cover 20 is fully opened, that is, the box cover 20 is in an open state, the box cover 20 has a tendency to continue rotating in the first direction under the elastic force of the deformation section 32, thereby maintaining stability in the open state, such as Figure 2Similarly, when the box cover 20 is in the open state, the box cover 20 is rotated in the second direction to gradually close the box cover 20. When the box cover 20 is rotated in the second direction by an angle exceeding 45°, the deformation section 32 provides an elastic force for the box cover 20 to continue rotating in the second direction. In this way, after the box cover 20 is completely closed, that is, the box cover 20 is in the closed state, the box cover 20 has a tendency to continue rotating in the second direction under the elastic force of the deformation section 32, so that the box cover 20 can be stably maintained in the closed state. Figure 1 , wherein the second direction is opposite to the first direction, for example, when the first direction is clockwise, the second direction is counterclockwise.

[0036] The earphone charging box provided in the present application is compared with the prior art. The box cover 20 is connected to the base body 10 by rotation around the first center line a, so that the box cover 20 can switch between the closed state and the open state when it rotates. The connecting section 31 is connected to the base body 10 by rotation around the second center line b parallel to the first center line a, so that when the box cover 20 rotates around the first center line a, the deformation section 32 is driven to rotate around the second center line b, and the deformation section 32 is elastically deformed. When the box cover 20 is rotated to the closed state or the open state, the two deformation sections 32 work together to stably maintain the box cover 20 in the closed state and the open state. The magnet is eliminated, which is beneficial to reducing material costs and at the same time beneficial to reducing the weight of the earphone charging box. Moreover, since the two deformation sections 32 are connected by the connecting section 31, when assembling the elastic member 30, it is only necessary to connect the connecting section 31 to the base body 10 and the two deformation sections 32 to the box cover 20. The assembly process is small and the assembly is simple, which is beneficial to reducing the production cost of the earphone charging box.

[0037] Specifically in this embodiment, the elastic member 30 is an integrated structure, that is, the connecting section 31 and the two deformation sections 32 are integrally formed, and the process is simple and the manufacturing is simple.

[0038] In one embodiment of this application, please refer to Figure 3 and Figure 4 A bracket 40 is installed on the seat body 10, and the connecting section 31 is rotatably connected to the bracket 40.

[0039] Optionally, the bracket 40 is disposed on a side of the base 10 facing away from the box cover 20 .

[0040] The bracket 40 can be fixed to the side of the base 10 away from the box cover 20 by means of screw connection, buckle connection, clamping connection or bonding.

[0041] By rotatably connecting the connecting section 31 and the bracket 40, the connecting section 31 and the seat body 10 are rotatably connected, and the bracket 40 can be an original component of the earphone charging box or a newly added component. Therefore, when the elastic member 30 is rotatably connected to the seat body 10, there is no need to make major changes to the seat body 10, which is beneficial to reducing production costs.

[0042] In one embodiment of the present application, see Figure 5 The bracket 40 is provided with two support parts 41 , which are spaced apart along the second direction. The support parts 41 are provided with grooves 411 , and the two ends of the connecting section 31 are movably inserted into the grooves 411 on the two support parts 41 .

[0043] Optionally, two support portions 41 are respectively disposed at two ends of one side of the bracket 40 .

[0044] By movably inserting the two ends of the connecting section 31 into the grooves 411 on the two supporting parts 41 , the connecting section 31 and the bracket 40 are connected to each other in a rotational manner around the second direction, which facilitates assembly.

[0045] Optionally, the groove 411 is an arc-shaped groove, which effectively ensures that the part of the connecting section 31 rotates smoothly in the groove 411. Of course, in other embodiments, the groove 411 can also be V-shaped or rectangular.

[0046] In one embodiment of the present application, a blocking portion 42 is further provided on the bracket 40, and the blocking portion 42 is arranged between the two supporting portions 41 along the second direction, and the blocking portion 42 and the supporting portion 41 are arranged at intervals along a third direction perpendicular to the second direction, the opening of the groove 411 faces the blocking portion 42, and the connecting section 31 is arranged between the blocking portion 42 and the supporting portion 41 along the third direction.

[0047] Specifically, the blocking portion 42 and the supporting portion 41 are located on the same side of the bracket 40 .

[0048] Optionally, there are two blocking portions 42 , one of which is close to one of the supporting portions 41 , and the other blocking portion 42 is close to the other supporting portion 41 .

[0049] When the elastic member 30 and the bracket 40 are assembled, the connecting section 31 is first placed between the supporting portion 41 and the blocking portion 42 , and then the connecting section 31 is inserted into the groove 411 along the third direction.

[0050] By providing the blocking portion 42 and positioning the connecting section 31 between the blocking portion 42 and the supporting portion 41 along the third direction, the connecting section 31 is effectively prevented from being separated from the bracket 40 , thereby improving the stability of the connecting section 31 inserted into the groove 411 .

[0051] In one embodiment of this application, please refer to Figure 4 and Figure 6 The earphone charging box also includes a control board 50 and a flexible circuit board 60. The control board 50 is installed on the side of the base 10 away from the box cover 20. The bracket 40 is arranged on the side of the control board 50 away from the base 10. One end of the flexible circuit board 60 is clamped between the bracket 40 and the control board 50 and is electrically connected to the control board 50.

[0052] The flexible circuit board 60 is used to realize the electrical connection between the electrical components on the earphone charging box and the control board 50 , and the bracket 40 and the control board 50 are connected to the base 10 together.

[0053] The bracket 40 cooperates with the base 10 to clamp one end of the flexible circuit board 60 , thereby effectively ensuring the stability of the connection between the flexible circuit board 60 and the control board 50 , while increasing the use function of the bracket 40 .

[0054] In one embodiment of this application, please refer to Figure 4 and Figure 5 The deformation section 32 includes a rebound portion 321, which is U-shaped and is always in a compressed state, so that after the box cover 20 rotates in a preset direction by a preset angle, the rebound portion 321 provides a thrust for the box cover 20 to continue rotating in the preset direction.

[0055] For example, when the box cover 20 switches from the closed state to the open state, the box cover 20 rotates around the first center line a in the first direction, and the box cover 20 drives the deformation section 32 to rotate around the second center line b in the second direction, and the second direction is opposite to the first direction. In the interval where the rotation angle of the box cover 20 is greater than 0° and less than 45°, as the box cover 20 rotates, the rebound portion 321 is continuously compressed. In this process, the rebound portion 321 provides a thrust for the box cover 20 to rotate in the second direction, that is, the rebound portion 321 provides a thrust for the box cover 20 to rotate in the second direction. resistance to rotation in the first direction; when the rotation angle of the box cover 20 is 45°, the rebound portion 321 is compressed to the maximum extent; when the rotation angle of the box cover 20 is greater than 45, as the box cover 20 rotates, the rebound portion 321 rebounds continuously, and in this process, the rebound portion 321 provides a thrust for the box cover 20 to rotate along the first direction, that is, the rebound portion 321 provides an assisting force for the box cover 20 to rotate along the first direction, so that when the box cover 20 is in the open state, the rebound portion 321 can push the box cover 20 to stably remain in the open state.

[0056] Similarly, when the box cover 20 switches from the open state to the closed state, the box cover 20 rotates around the first center line a in the second direction, and the box cover 20 drives the deformation section 32 to rotate around the second center line b in the first direction. In the interval where the rotation angle of the box cover 20 is greater than 0° and less than 45°, as the box cover 20 rotates, the rebound portion 321 is continuously compressed. In this process, the rebound portion 321 provides a thrust for the box cover 20 to rotate in the first direction, that is, the rebound portion 321 provides a thrust for the box cover 20 to rotate in the second direction. resistance; when the rotation angle of the box cover 20 is 45°, the rebound portion 321 is compressed to the maximum amplitude; when the rotation angle of the box cover 20 is greater than 45, as the box cover 20 rotates, the rebound portion 321 rebounds continuously, and in this process, the rebound portion 321 provides a thrust for the box cover 20 to rotate in the second direction, that is, the rebound portion 321 provides an assisting force for the box cover 20 to rotate in the first direction, so that when the box cover 20 is in the closed state, the rebound portion 321 can push the box cover 20 to stably remain in the closed state.

[0057] In one embodiment of the present application, a spiral structure 322 is formed in the middle of the rebound portion 321 .

[0058] The spiral structure 322 in the middle of the rebound portion 321 is helpful to increase the elastic force and structural strength of the rebound portion 321 , so that the rebound portion 321 can stably keep the box cover 20 in a closed state or an open state.

[0059] In one embodiment of the present application, the deformation section 32 further includes a first arc portion 323 and a second arc portion 324 . The first arc portion 323 is connected between the rebound portion 321 and the connecting section 31 , and the second arc portion 324 is connected between the rebound portion 321 and the box cover 20 .

[0060] It can be understood that the first arc portion 323 , the rebound portion 321 and the second arc portion 324 are connected in sequence, so that the deformation section 32 is roughly a circuitous structure, which is conducive to increasing the deformation amount of the deformation section 32 and improving the elastic force of the entire deformation section 32 .

[0061] In one embodiment of this application, please refer to Figure 4 and Figure 6 The earphone charging box also includes a rotating shaft 70. A transfer block 21 is provided at one end of the box cover 20. The transfer block 21 extends out of the box cover 20 toward the side of the seat body. The middle part of the transfer block 21 is rotatably connected to one end of the seat body through the rotating shaft 70. The end of the deformation section 32 away from the connecting section 31 is rotatably connected to the end of the transfer block 21 away from the box cover 20.

[0062] Specifically, an adapter hole 22 is provided at one end of the adapter block 21 away from the box cover 20, and the central axis of the adapter hole 22 is parallel to the first center line a and the second center line b. One end of the second arc portion 324 away from the rebound portion 321 is movably inserted in the adapter hole 22 so that the second arc portion 324 can rotate relative to the box cover 20.

[0063] The first center line a is the center axis of the rotating shaft 70 , and the second center line b is the center axis of the connecting section 31 .

[0064] In this way, when the box cover 20 rotates in the first direction around the first center line a, the box cover 20 drives the deformation section 32 to rotate in the second direction around the second center line b through the adapter block 21, the connecting section 31 rotates relative to the groove 411, and the end of the second arc portion 324 away from the rebound portion 321 rotates relative to the adapter hole 22.

[0065] The earphone charging box also includes a bottom cover, which is installed on the side of the base 10 away from the earphone receiving groove 11 and forms a storage cavity with the base 10. The storage cavity is used to accommodate electrical components such as circuit boards and batteries.

[0066] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
