[0041] Example 1

[0042] like Figures 1-4 As shown, this embodiment provides an earphone box, which includes a base 1, a locking assembly 3 and two top cover assemblies 2. Specifically, the top wall of the base 1 is provided with two mounting grooves 11 for mounting earphones at intervals along a first direction, and the top wall is also provided with a support column 16 located between the two mounting grooves 11; the two top cover assemblies 2 are symmetrically arranged on both sides of the support column 16 along a second direction, and the top cover assemblies 2 include an upper cover 21 and a first elastic member 22. The upper covers 21 of the two top cover assemblies 2 are slidably connected to the base 1 along the second direction. One end of the first elastic member 22 is connected to the upper cover 21 and the other end is connected to the base 1. The first elastic member 22 is used to drive the upper cover 21 to move away The locking assembly 3 is rotatably connected to the support column 16. The locking assembly 3 is provided with first engaging portions 321 at both ends along the second direction. The upper cover 21 is provided with second engaging portions 211 corresponding to the first engaging portions 321. When the two top cover assemblies 2 are in the closed state, the two first engaging portions 321 can be engaged with the second engaging portions 211 of the two upper covers 21. The locking assembly 3 is rotated relative to the support column 16 to engage or disengage the first engaging portions 321 with the second engaging portions 211. In this embodiment, the first direction is X, the second direction is Y, and the first direction is perpendicular to the second direction.

[0043] During use, the earphones are placed in the mounting groove 11 of the base 1. When the earphone box needs to be switched from the closed state to the open state, the locking assembly 3 is manually driven to rotate relative to the support column 16, and the two first engaging portions 321 of the locking assembly 3 disengage the two second engaging portions 211. At this time, the first elastic member 22 of the top cover assembly 2 drives the upper cover 21 to move away from the support column 16 to form the open state. When the earphone box needs to be switched from the open state to the closed state, the two upper covers 21 are manually clamped. The two upper covers 21 overcome the elastic force of the two first elastic members 22 and move toward the support column 16 to the closed state. The locking assembly 3 is then rotated relative to the support column 16 so that the two first engaging portions 321 engage the two second engaging portions 211, thereby maintaining the earphone box in the closed state. The design of this embodiment not only makes the earphone box more stylish and beautiful, but also improves the convenience and practicality of operation, meets the user's pursuit of product innovation and personalization, and provides users with a better user experience.

[0044] In this embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, the locking assembly 3 includes a first rotating shaft 31 and two first locking blocks 32. The first rotating shaft 31 is mounted on the top surface of the support column 16. The two first locking blocks 32 extend sequentially along the second direction. The ends of the two first locking blocks 32 that are closer to each other are rotatably connected to the first rotating shaft 31. The ends of the two first locking blocks 32 that are separated from each other are provided with a first engaging portion 321. When the first locking blocks 32 are rotated relative to the first rotating shaft 31 in a direction closer to the upper cover 21, the first engaging portion 321 can engage with the second engaging portion 211. The two first locking blocks 32 can be adjusted separately, allowing each upper cover 21 to be opened separately, improving the user experience.

[0045] In this embodiment, the top surface of the support column 16 is provided with a second receiving groove 162. When the first clamping portion 321 is clamped to the second clamping portion 211, the first locking block 32 is partially located in the second receiving groove 162.

[0046] Preferably, the locking assembly 3 also includes a torsion spring 33, and the ends of the two first locking blocks 32 that are close to each other are rotatably connected to the first rotating shaft 31 through the torsion spring 33. The torsion spring 33 applies a torque to the two first locking blocks 32 to rotate toward the upper cover 21, so that the first locking blocks 32 always have a downward elastic force. When the two upper covers 21 move to the closed state, the first locking blocks 32 will automatically clamp the two upper covers 21 to achieve the purpose of closing and locking the covers.

[0047] In this embodiment, the first clamping portion 321 is a flange folded toward one side of the upper cover 21, and the side walls of the two upper covers 21 facing away from each other form the second clamping portion 211. When the two top cover assemblies 2 are in the closed state, the two flanges can be hooked on the side walls of the two upper covers 21 facing away from each other to limit the two upper covers 21 from moving in the direction away from the support column 16.

[0048] In this embodiment, the earphone box further includes a housing 4, with the base 1 mounted within the housing 4. The bottom surface of the upper cover 21 is in contact with and slidably connected to the top surface of the housing 4, providing support for the upper cover 21. Preferably, guide surfaces 12 are provided at both ends of the base 1 along the first direction, and the guide surfaces 12 are in contact with the inner wall of the upper cover 21. The guide surfaces 12 guide the upper cover 21, thereby improving the movement accuracy of the upper cover 21.

[0049] Preferably, if Figure 3 As shown, the guide surface 12 is provided with a limiting groove 13 extending along the second direction, and the inner wall of the upper cover 21 is provided with a limiting protrusion 212 corresponding to the limiting groove 13. The limiting protrusion 212 is slidably connected in the limiting groove 13. The limiting groove 13 is used to limit the maximum stroke of the upper cover 21 moving along the second direction. The limiting groove 13 can guide and limit the limiting protrusion 212 to prevent the upper cover 21 from separating from the earphone box.

[0050] In this embodiment, Figure 6 As shown, the upper cover 21 is provided with an avoidance hole 213 for avoiding the support column 16. When the earphone box is in the closed state, the side walls of the support column 16 fit into the avoidance holes 213 of the two upper covers 21 to limit the minimum distance between the two upper covers 21.

[0051] like Figure 2 and Figure 4 As shown, in this embodiment, the first elastic member 22 is a spring, and the base 1 is provided with a guide groove 14 extending along the second direction. The first elastic member 22 is located in the guide groove 14. The guide groove 14 can improve the guidance of the spring, improve the stability of the spring compression or stretching, and improve the reliability of use.

[0052] In this embodiment, each top cover assembly 2 includes two first elastic members 22, and the two first elastic members 22 are arranged at intervals along the first direction. Therefore, a total of four guide grooves 14 are provided on the base 1, and a boss 15 for connecting the spring is provided between the two guide grooves 14 on one side. The boss 15 is respectively connected to the first elastic members 22 of the two top cover assemblies 2 on both sides along the second direction.

[0053] Example 2

[0054] like Figure 5-Figure 7As shown, this embodiment provides an earphone box. The structure of the earphone box provided in this embodiment is basically the same as that of the embodiment 1, and only the structure of the locking component 3 is partially different. This embodiment will no longer repeat the structure that is the same as that of the embodiment 1.

[0055] In this embodiment, the locking assembly 3 includes a second rotating shaft 34 and a second locking block 35 extending along the second direction. The second rotating shaft 34 is installed on the top surface of the support column 16. First clamping parts 321 are provided at both ends of the second locking block 35. The middle rotation of the second locking block 35 is connected to the second rotating shaft 34. The second locking block 35 can be rotated to the first position and the second position relative to the second rotating shaft 34. When the second locking block 35 is in the first position, when one first clamping part 321 is clamped to the corresponding second clamping part 211, the other first clamping part 321 is disengaged from the corresponding second clamping part 211; when the second locking block 35 is in the second position, the two first clamping parts 321 are simultaneously clamped to the corresponding second clamping part 211.

[0056] When the earphone box needs to be switched from the closed state to the open state, the first clamping portion 321 of the first end of the second locking block 35 continues to move toward the direction close to the upper cover 21. According to the lever principle, the first clamping portion 321 of the second end of the second locking block 35 is disengaged from the second clamping portion 211, and the first elastic member 22 corresponding to the second end of the second locking block 35 automatically pops open the upper cover 21; similarly, the second end of the second locking block 35 is pressed, the first clamping portion 321 of the second end of the second locking block 35 is disengaged from the second clamping portion 211, and the first elastic member 22 corresponding to the first end of the second locking block 35 automatically pops open the upper cover 21; the earphone box is switched from the closed state to the open state. When the earphone box needs to be switched from an open state to a closed state, one upper cover 21 is first closed into place, and then the other upper cover 21 is closed. When the two upper covers 21 are moved to the closed state, the second locking block 35 is in the second position, and the two first clamping portions 321 are simultaneously clamped to the corresponding second clamping portions 211.

[0057] Preferably, the locking assembly 3 also includes two second elastic members 36, symmetrically positioned on either side of the second rotating shaft 34 along the second direction. The second elastic members 36 are located between the second locking block 35 and the support column 16. The two second elastic members 36 are used to drive the second locking block 35 to rotate to the second position. When the earphone case is not subjected to external force, the second locking block 35 remains horizontal under the elastic force of the two second elastic members 36. When the two upper covers 21 are moved to the closed position, the two second elastic members 36 automatically lock the two upper covers 21.

[0058] In this embodiment, a first receiving groove 161 is provided on the top surface of the support column 16, and the second elastic member 36 and a portion of the second locking block 35 are located in the first receiving groove 161. In this embodiment, the second elastic member 36 is a spring, which is located between the second locking block 35 and the bottom of the first receiving groove 161.

[0059] In this embodiment, the first engaging portion 321 is a buckle, and the second engaging portion 211 is a slot. When the two top cover assemblies 2 are in the closed state, the buckle engages with the slot. When the second locking block 35 is in the second position, the buckle is partially located within the slot, allowing the buckle to continue moving toward the slot. When the second locking block 35 is in the first position, the buckle at one end of the second locking block 35 is completely located within the slot, and the buckle at the other end of the second locking block 35 is disengaged from the slot.

[0060] Preferably, chamfers are provided on the opposite sides of the two buckles. When the two upper covers 21 move to the closed state, the chamfers first contact the upper covers 21, thereby driving the buckles to move upward. After the two upper covers 21 move to the closed state, the buckles fall into the card slots.

[0061] Note that the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention. Therefore, while the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the scope of the appended claims.
