Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. 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 7 , the earphone charging box provided in the embodiment of the present application is now described.

[0031] See also Figure 1 and Figure 2 The earphone charging box includes: a box body 10, a spring piece 30 and a box cover 20. The box body 10 is provided with an inner cavity 11 and an avoidance opening 12. The avoidance opening 12 is provided on one side of the box body 10 and communicates with the inner cavity 11. The spring piece 30 is provided in the inner cavity 11 and is provided corresponding to the avoidance opening 12. The spring piece 30 includes a bending portion 31. A transfer block 21 is provided on one side of the box cover 20. The transfer block 21 is rotatably connected to the side of the box body 10 provided with the avoidance opening 12, so that the box cover 20 can switch between a closed state and an open state; when the box cover 20 is in an open state, the transfer block 21 abuts against the box body 10 along a first direction, and a part of the transfer block 21 extends into the inner cavity 11 at the avoidance opening 12, and abuts against the bending portion 31 along a second direction that is the first direction, so as to keep the box cover 20 in an open state.

[0032] The box body 10 is used to store the wireless headset. A charging assembly is also provided in the box body 10. The charging assembly is used to charge the wireless headset stored in the box body 10. The box cover 20 is used to cover the box body 10 so that the wireless headset can be stably stored in the box body 10.

[0033] By rotating the adapter block 21 and the side of the box body 10 provided with the avoidance opening 12, the adapter block 21 can be rotatably connected relative to the box body 10, and when the adapter block 21 rotates, the box cover 20 is driven to rotate synchronously relative to the box body 10, so that the box cover 20 can be switched between a closed state and an open state. The closed state means that the box cover 20 is closed to the box body 10, so that the wireless earphones stored in the box body 10 cannot fall out, and the open state means that the angle between the box cover 20 and the box body 10 is greater than or equal to 90°, which can facilitate the user to take the wireless earphones out of the box body 10.

[0034] Exemplarily, in the process of opening the box cover 20, the adapter block 21 drives the box cover 20 to rotate relative to the box body 10 in a first direction. When the adapter block 21 rotates in the first direction by a first preset angle, the adapter block 21 contacts and abuts against the bent portion 31 of the spring sheet 30. Under the reaction force, the bent portion 31 of the spring sheet 30 provides the adapter block 21 with an elastic force opposite to the first direction. When the adapter block 21 rotates by a second preset angle, the bent portion 31 of the spring sheet 30 provides the adapter block 21 with an elastic force in the same direction as the first direction. When the adapter block 21 rotates by a third preset angle, the box cover 20 is opened. 20 is in the open state, and the adapter block 21 abuts against the box body 10, so that the adapter block 21 cannot continue to rotate in the first direction. At this time, the adapter block 21 has a tendency to continue to rotate in the first direction under the elastic force of the bending portion 31. It can be understood that, with the cooperation between the box body 10 and the bending portion 31, the adapter block 21 can neither rotate in the first direction nor in the second direction opposite to the first direction when there is no external force, thereby maintaining the adapter block 21 at the third preset angle, thereby achieving the goal of maintaining the box cover 20 in the open state.

[0035] The second preset angle is greater than the first preset angle, and the third preset angle is greater than or equal to the second preset angle. For example, the first preset angle is greater than 80° and less than 90°, the second preset angle is greater than 90° and less than or equal to 105°, and the third preset angle is greater than 90° and less than or equal to 105°.

[0036] The headphone charging box provided by the present application is compared with the prior art. The adapter block 21 of the headphone charging box of the present application is rotatably connected to the box body 10, so that the box cover 20 can switch between a closed state and an open state; when the adapter block 21 rotates along a first direction, it drives the box cover 20 to switch from a closed state to an open state. When the box cover 20 is in the open state, the adapter block 21 abuts against the box body 10 along the first direction to prevent the adapter block 21 from continuing to rotate along the first direction. Part of the adapter block 21 extends into the inner cavity 11 at the avoidance opening 12 and abuts against the bending portion 31 along the second direction, so that the adapter block 21 cannot rotate along the second direction when no external force is applied, thereby achieving the goal of keeping the box cover 20 in the open state. The headphone charging box of the present application keeps the box cover 20 in the open state by using a spring sheet 30 to cooperate with the box body 10. Compared with a magnet, the material cost of the spring sheet 30 is relatively low, and it is sufficient to fix the spring sheet 30 in the box body 10, which is conducive to simplifying the structure of the box body 10 and the box cover 20, and the assembly process is simple, which is conducive to reducing production costs.

[0037] In one embodiment of the present application, see Figure 1 and Figure 2 The box body 10 includes a bottom cover 13 and a middle frame 14. The middle frame 14 is connected to the bottom cover 13 and surrounds an inner cavity 11. The adapter block 21 is rotatably connected to the middle frame 14. When the box cover 20 is in an open state, the adapter block 21 is located between the middle frame 14 and the bending portion 31, and the opposite side surfaces of the adapter block 21 are respectively in contact with the middle frame 14 and the bending portion 31.

[0038] See also Figure 1 and Figure 3 The circumferential edge of the middle frame 14 is connected to the circumferential edge of the bottom cover 13. When the box cover 20 is in a closed state, the middle frame 14 is located between the bottom cover 13 and the box cover 20, and the escape opening 12 runs through one side of the bottom cover 13 and the middle frame 14. The adapter block 21 is provided with a rotating shaft 212 at both opposite ends, and the escape opening 12 is provided with a shaft hole 141 at both opposite ends. The two rotating shafts 212 are movably inserted into the two shaft holes 141 respectively, so as to realize the rotation connection between the adapter block 21 and the middle frame 14.

[0039] When the box cover 20 is in the open state, the adapter block 21 extends into the inner cavity 11 and is located between the middle frame 14 and the bending portion 31, and one side of the portion of the adapter block 21 extending into the inner cavity 11 abuts against the inner wall surface of the middle frame 14, and the other side of the portion of the adapter block 21 extending into the inner cavity 11 abuts against one side of the bending portion 31. It can be understood that when the box cover 20 is in the open state, the middle frame 14 and the bending portion 31 cooperate to clamp the adapter block 21 to achieve positioning of the adapter block 21 to keep the box cover 20 in the open state.

[0040] In one embodiment of the present application, see Figure 4 and Figure 7A limiting groove 142 is provided on the inner wall of the middle frame 14 , and the bending portion 31 is located in the limiting groove 142 .

[0041] The limiting groove 142 is arranged close to the avoidance opening 12, and the limiting groove 142 is connected with the inner cavity 11 and the avoidance opening 12, and the width of the limiting groove 142 is slightly larger than the width of the bending portion 31. By using the limiting groove 142 to limit the width direction of the bending portion 31, the bending portion 31 is effectively prevented from having a large lateral displacement when subjected to force, so that when the box cover 20 is in the open state, the bending portion 31 can be stably abutted against the adapter block 21.

[0042] In one embodiment of the present application, see Figure 4 and Figure 5 A positioning column 143 and a connecting column 144 are provided on the inner wall of the middle frame 14, and a connecting hole 145 is provided on the connecting column 144. The spring piece 30 also includes a fixing portion 32 connected to the bending portion 31, and a positioning hole 321 and a fixing hole 322 are provided on the fixing portion 32. The positioning column 143 passes through the positioning hole 321, and the fixing hole 322 is correspondingly connected to the connecting hole 145.

[0043] See also Figure 6 and Figure 7 During the assembly process of the spring piece 30 and the middle frame 14, the fixing part 32 is placed on the middle frame 14, and the positioning column 143 is passed through the positioning hole 321, the fixing hole 322 is connected to the connecting hole 145 accordingly, and fasteners such as screws are used to pass through the fixing hole 322 and the connecting hole 145 to connect the fixing part 32 to the inner wall of the middle frame 14.

[0044] By cooperating with the positioning column 143 and the positioning hole 321, the fixing part 32 is initially positioned to avoid a large offset of the fixing part 32 in the subsequent assembly steps, which is beneficial to improving work efficiency. At the same time, the fixing part 32 is fixed by the positioning column 143 and the connecting column 144, which is beneficial to improving the stability of the spring piece 30 assembled on the middle frame 14.

[0045] In one embodiment of the present application, see Figure 4 and Figure 5 There are multiple positioning posts 143 , which are spaced apart along the circumference of the connecting post 144 . The number of positioning holes 321 is equal to the number of positioning posts 143 , and the multiple positioning posts 143 pass through the multiple positioning holes 321 respectively.

[0046] Optionally, the number of positioning columns 143 is three, and the three positioning columns 143 are arranged at equal distances along the circumference of the connecting column 144. The number of positioning holes 321 is also three more, and the three positioning holes 321 are arranged at equal distances along the circumference of the fixing hole 322. The three positioning columns 143 pass through the multiple positioning holes 321 respectively.

[0047] By providing a plurality of positioning posts 143 and a plurality of positioning holes 321 , and passing the plurality of positioning posts 143 through the plurality of positioning holes 321 , respectively, it is helpful to improve the stability of positioning the fixing portion 32 .

[0048] In one embodiment of the present application, see Figure 2 and Figure 5 The spring piece 30 also includes a middle portion 33, one end of the middle portion 33 is connected to an edge of a side of the fixing portion 32 close to the avoidance opening 12, and the middle portion 33 extends out of the fixing portion 32 toward the side of the middle frame 14, and one end of the middle portion 33 away from the fixing portion 32 is connected to the bending portion 31.

[0049] Optionally, the fixing portion 32, the middle portion 33 and the bending portion 31 are sequentially connected and integrally formed. The middle portion 33 extends out of the fixing portion 32 toward the side of the middle frame 14, so that the middle portion 33 and the fixing portion 32 roughly form an L-shaped structure.

[0050] Optionally, the bending portion 31 is arc-shaped.

[0051] By setting the bending portion 31 to be arc-shaped, the movement of the adapter block 21 can be guided, so that when the adapter block 21 is rotated by an external force, under the guidance of the bending portion 31, the adapter block 21 can easily enter between the bending portion 31 and the middle frame 14, or detach from the bending portion 31 and the middle frame 14, so that the box cover 20 can be switched between the closed state and the open state, which saves effort and is convenient for users to operate.

[0052] In one embodiment of the present application, see Figure 2 The bending portion 31 is provided with a first inclined surface 311 , and the adapter block 21 is provided with a second inclined surface 211 . When the box cover 20 is in the open state, the second inclined surface 211 contacts the first inclined surface 311 .

[0053] Specifically, the first inclined surface 311 is inclined toward the middle frame 14, and the second inclined surface 211 is inclined away from the middle frame 14. When the box cover 20 is in the open state, the adapter block 21 is located between the middle frame 14 and the bending portion 31, and the second inclined surface 211 of the adapter block 21 contacts the first inclined surface 311 of the bending portion 31, which is beneficial to improving the stability of the abutment between the adapter block 21 and the bending portion 31, so that the adapter block 21 can be stably located between the middle frame 14 and the bending portion 31, thereby helping to improve the stability of keeping the box cover 20 in the open state.

[0054] In one embodiment of the present application, see Figure 2 The avoidance opening 12 is provided with a third inclined surface 121 , which is inclined toward the inner cavity 11 . When the box cover 20 is in a closed state, the adapter block 21 is blocked in the avoidance opening 12 , and the third inclined surface 121 contacts the second inclined surface 211 .

[0055] When the box cover 20 is in a closed state, the adapter block 21 is used to block the avoidance opening 12, and the third inclined surface 121 contacts the second inclined surface 211, which will not damage the overall appearance of the earphone charging box and is beneficial to improving the aesthetics of the overall appearance of the earphone charging box.

[0056] In one embodiment of the present application, see Figure 3 The number of the spring pieces 30 is two, and the two spring pieces 30 are arranged at an interval.

[0057] When the box cover 20 is in the open state, the adapter block 21 abuts against the two spring sheets 30 at the same time, which helps to stably keep the box cover 20 in the open state.

[0058] In some embodiments of the present application, when the box cover 20 is closed on the box body 10, the box cover 20 can be kept in the closed state by magnet attraction. It can be understood that compared with the box cover 20 of the traditional earphone charging box, which is kept in the open state and the closed state by magnets, the box cover 20 of the earphone charging box of the present application is kept in the open state by the spring 30, and the box cover 20 is kept in the closed state by the magnet, which is conducive to reducing the number of magnets used, thereby reducing costs.

[0059] 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.
