In this embodiment, the first direction is X, the second direction is Y, and the first direction is perpendicular to the second direction.

[0039] In use, the earphone is arranged in the installation groove 11 of the base 1. When it is necessary to switch the earphone charging case from the closed cover state to the open cover state, manually drive the locking button 31 to move away from the support column 16 against the elastic force of the second elastic member 32. At this time, the two first clamping portions 311 of the locking button 31 disengage from the second clamping portions 211 of the two upper covers 21, and 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 an open cover state. When it is necessary to switch the earphone charging case from the open cover state to the closed cover state, manually clamp the two upper covers 21, and the two upper covers 21 move towards the support column 16 against the elastic force of the two first elastic members 22 to the closed cover state. The second elastic member 32 applies an elastic force towards the support column 16 to the locking button 31, so that the two first clamping portions 311 are clamped to the second clamping portions 211 of the two upper covers 21, so that the earphone charging case remains in the closed cover state. In this embodiment, through the cooperation of the second elastic member 32 and the locking button 31, the first clamping portion 311 is clamped or disengaged from the second clamping portion 211, the operation is simple, the convenience and practicality of the operation are improved, and the appearance of the earphone charging case is made more fashionable and beautiful, meeting the user's pursuit of product innovation and personalization, and bringing a better use experience to the user.

[0040] Preferably, as Figure 5 and Figure 6 shown, a first spiral inclined surface 161 is provided on one side of the support column 16 facing the locking button 31, and a second spiral inclined surface 314 matching the first spiral inclined surface 161 is provided on one side of the locking button 31 facing the support column 16. The first spiral inclined surface 161 is slidably connected to the second spiral inclined surface 314 to adjust the distance between the support column 16 and the locking button 31. When it is necessary to switch the earphone charging case from the closed cover state to the open cover state, only need to turn the locking button 31, the first spiral inclined surface 161 guides the second spiral inclined surface 314, increases the distance between the support column 16 and the locking button 31, and realizes the disengagement of the first clamping portion 311 from the second clamping portion 211; when it is necessary to switch the earphone charging case from the open cover state to the closed cover state, cancel the rotational driving force of the locking button 31, the second elastic member 32 applies an elastic force towards the support column 16 to the locking button 31, the locking button 31 rotates in the reverse direction, and the locking button 31 automatically resets, reducing the distance between the support column 16 and the locking button 31, so that the first clamping portion 311 can automatically clamp the second clamping portion 211.

[0041] Preferably, on the side of the support post 16 facing the locking button 31, there are at least two first spiral inclined surfaces 161 connected end to end. A first stop surface 162 is arranged between the two first spiral inclined surfaces 161. On the side of the locking button 31 facing the support post 16, there is a second stop surface 315. When the earphone charging case is in the closed cover state, the second stop surface 315 abuts against the first stop surface 162. When the locking button 31 is in the reset state, the first stop surface 162 and the second stop surface 315 abut against each other to ensure that the first latching portion 311 and the second latching portion 211 correspond to each other. The rotation direction of the locking button 31 to increase the distance between the support post 16 and the locking button 31 is the direction in which the first stop surface 162 and the second stop surface 315 move away from each other.

[0042] Preferably, both the first spiral inclined surface 161 and the second spiral inclined surface 314 are high-gloss surfaces, which reduces the friction between the first spiral inclined surface 161 and the second spiral inclined surface 314, reduces the force for driving the rotation of the locking button 31, improves the operation convenience. At the same time, the smaller friction facilitates the second elastic member 32 to drive the locking button 31 to rotate and reset.

[0043] In this embodiment, the first latching portion 311 is a buckle, and the second latching portion 211 is a slot. When the two top cover assemblies 2 are in the closed cover state, the buckle is latched in the slot to limit the displacement of the upper cover 21 in the second direction. When the distance between the support post 16 and the locking button 31 increases, the buckle moves upward to disengage the buckle from the slot. When the distance between the support post 16 and the locking button 31 decreases, the buckle moves downward to latch the buckle in the slot.

[0044] Preferably, chamfered corners 312 are provided at both ends of the buckle along the rotation direction; and / or chamfers 313 are provided on the opposite sides of the two buckles. In this embodiment, chamfered corners 312 are provided at both ends of the buckle along the rotation direction.

Further, chamfers 313 are provided on the opposite sides of the two buckles. During the process of the two upper covers 21 moving to the closed cover state, the locking button 31 is in the reset state, and the chamfers 313 contact the upper cover 21 first, thereby driving the buckle to move upward. After the two upper covers 21 move to the closed cover state, the buckle automatically falls into the slot.

[0045] In this embodiment, as Figure 4 shown, the second elastic member 32 is a tension spring. An annular groove 163 is provided on the top surface of the support post 16. The tension spring is embedded in the annular groove 163, and one end of the tension spring is connected to the bottom of the annular groove 163, and the other end is connected to the locking button 31. The provision of the annular groove 163 improves the stability of the tension spring during compression or stretching and improves the use reliability.

[0046] In this embodiment, the earphone charging case further includes a housing 4. The base 1 is installed inside the housing 4, and the bottom surface of the upper cover 21 is attached to and slidably connected to the top surface of the housing 4. The housing 4 can support the upper cover 21. Preferably, guiding surfaces 12 are provided at both ends of the base 1 along a first direction, and the guiding surfaces 12 are attached to the inner wall of the upper cover 21. The guiding surfaces 12 can guide the upper cover 21 and improve the movement precision of the upper cover 21.
