[0046] Please see Figures 1 to 4 This embodiment provides an earphone case, which includes a case body 1 and a case lid 2. The case body 1 is provided with a receiving slot 18 for storing wireless earphones 100. The case lid 2 has an open state and a closed state. When the case lid 2 is in the open state, the receiving slot 18 is exposed so that the user can easily take out and store the wireless earphones 100. When the case lid 2 is in the closed state, the receiving slot 18 is closed so as to store the wireless earphones 100.

[0047] Based on the above, combined with Figures 5 to 13 In this embodiment, the box body 1 is provided with a locking structure, which includes a pull block 11, a locking rod 12 and a first reset member 131. That is, the box body 1 is provided with a pull block 11, a locking rod 12 and a first reset member 131. The pull block 11 and the locking rod 12 are slidably connected to the box body 1 along a first direction. The pull block 11 can slide from the initial position relative to the box body 1 to the unlock position or the locked position along the first direction. During the process of the pull block 11 resetting from the unlock position to the initial position, the locking rod 12 stops the pull block 11. The pull block 11 can pull the locking rod 12 back into the box body 1. During the process of the pull block 11 resetting from the locked position to the initial position, the pull block 11 avoids the locking rod 12. The first reset member 131 can drive the locking rod 12 to reset to extend out of the box body 1.

[0048] The lid 2 is provided with a slot 21. The lid 2 can be fastened to the top of the body 1. The locking rod 12 extends out of the body 1 and is inserted into the slot 21, thereby locking the lid 2 and the body 1, thus preventing the lid 2 from being accidentally opened due to shaking of the headphone case.

[0049] Therefore, in this embodiment, the sliding block 11 can alternate between sliding from the initial position to the unlocked position and sliding from the initial position to the locked position. After sliding from the initial position to the unlocked position, the sliding block 11 returns to the initial position and pulls the locking lever 12 back into the case 1 during the reset process, thereby unlocking the case cover 2 and the case 1. This allows the user to open the case cover 2 to take out the wireless earphone 100 or put the wireless earphone 100 into the case 1. After sliding from the initial position to the locked position, the sliding block 11 returns to the initial position and avoids the locking lever 12 during the reset process, allowing the locking lever 12 to return to its original position, extend out of the case 1, and insert into the case cover 2. This locks the case cover 2 and the case 1, preventing the wireless earphone 100 from falling out of the earphone case due to the case cover 2 being accidentally opened, thereby improving the user experience.

[0050] Specifically, after the pull block 11 slides from the initial position to the unlocked position, during the process of the pull block 11 returning to the initial position, the locking rod 12 stops the pull block 11, thereby allowing the pull block 11 to pull the locking rod 12 back into the box body 1, thus unlocking the box cover 2 and the box body 1. The pull block 11, which has returned to the initial position, can slide to the locked position next time. Then, during the process of the pull block 11 returning to the initial position, the stop of the locking rod 12 on the pull block 11 is released, thereby allowing the locking rod 12 to return to the position of extending out of the box body 1 and inserting into the box cover 2, thus locking the box cover 2 and the box body 1. Moreover, after the pull block 11 slides from the initial position to the unlocked position next time, it can continue to pull the locking rod 12 back into the box body 1 during the process of returning to the initial position.

[0051] Based on the above description, in this embodiment, the pull block 11 can also slide relative to the box 1 in a direction perpendicular to the first direction. One end of the locking rod 12 is provided with a boss 121, and the boss 121 is provided with a first inclined surface 1211. When the pull block 11 slides from the initial position to the unlocked position, the first inclined surface 1211 can push against the pull block 11 and slide towards the side away from the boss 121 in a direction perpendicular to the first direction.

[0052] Specifically, in this embodiment, one end of the locking rod 12 is the stop end 123 and the other end is the insertion end 124. The box body 1 is provided with a through hole 191. The insertion end 124 can pass through the through hole 191 and extend out of the box body 1, thereby inserting into the box cover 2.

[0053] Along the first direction from the end away from the insertion end 124 to the end near the insertion end 124, the first inclined surface 1211 gradually tilts away from the locking bar 12. As a result, the pull block 11 can slide along the first inclined surface 1211 when sliding from the initial position to the unlocked position. The first inclined surface 1211 can push against the pull block 11 and slide in a direction perpendicular to the first direction toward the side away from the boss 121.

[0054] In addition, the locking structure also includes a second reset member 132. That is, the housing 1 is also provided with a second reset member 132. The second reset member 132 can drive the pull block 11 to reset in a direction perpendicular to the first direction after the pull block 11 disengages from the boss 121. That is, when the pull block 11 slides in the first direction to disengage from the first inclined surface 1211, the pull block 11 slides to the unlock position. At the same time, the second reset member 132 drives the pull block 11 to reset in a direction perpendicular to the first direction, so that the boss 121 can stop the pull block 11 in the first direction. Thus, when the pull block 11 resets from the unlock position to the initial position, the pull block 11 can push against the boss 121 in the first direction, thereby driving the locking rod 12 to move together, and then causing the locking rod 12 to retract into the housing 1.

[0055] For example, in this embodiment, the boss 121 is a frustum structure, and the diameter of the boss 121 gradually increases from the side away from the insertion end 124 to the side closer to the insertion end 124. Thus, the side of the frustum forms a first inclined surface 1211. Correspondingly, this embodiment provides two pull blocks 11, which are arranged opposite each other in a direction perpendicular to the first direction. This embodiment will be described with the two pull blocks 11 arranged opposite each other in a second direction. The two pull blocks 11 are respectively located on both sides of the locking rod 12 along the second direction. Therefore, when the pull block 11 moves along the first direction towards the through hole 191, that is, when the pull block 11 slides along the first direction from the initial position to the unlocked position, the pull block 11 moves along the first inclined surface 1211. 1. Slide, so that while the pull block 11 moves along the first direction, it also slides along the second direction toward the side away from the boss 121. After the pull block 11 slides along the first direction to disengage from the boss 121, the boss 121 releases its obstruction of the pull block 11. Under the action of the second reset member 132, the pull block 11 moves along the second direction toward the side close to the locking rod 12, so that it can overlap with the boss 121 along the first direction. That is, the boss 121 stops the pull block 11 on the side away from the through hole 191 along the first direction. Subsequently, when the pull block 11 is reset from the unlocked position to the initial position, the pull block 11 can push against the boss 121, thereby driving the locking rod 12 to move together, and thus causing the locking rod 12 to retract into the box 1.

[0056] It is understood that in other alternative embodiments, the locking structure may be provided with only one pull block 11, or the locking structure may be provided with three or more pull blocks 11 along the circumference of the boss 121. Accordingly, all pull blocks 11 can slide radially along the boss 121. This embodiment does not impose specific limitations on this.

[0057] It is also understood that in other alternative embodiments, the first inclined surface 1211 may also be a planar structure disposed on the side of the boss 121, and the pull block 11 is disposed correspondingly to the first inclined surface 1211, so that the first inclined surface 1211 can push the pull block 11 to slide in a direction perpendicular to the first direction. This embodiment does not impose any specific restrictions on this.

[0058] Furthermore, the pull block 11 is provided with a second inclined surface 111. During the process of the pull block 11 sliding from the initial position to the unlocked position, the second inclined surface 111 is in contact with the first inclined surface 1211. That is, along the first direction from the end away from the through hole 191 to the end close to the through hole 191, the second inclined surface 111 gradually tilts away from the lock rod 12. An unlocking block 14 is provided between the other end of the lock rod 12 and the boss 121. That is, an unlocking block 14 is provided between the insertion end 124 of the lock rod 12 and the boss 121. The unlocking block 14 is provided with a third inclined surface 141. The tilting direction of the third inclined surface 141 is opposite to that of the first inclined surface 1211. The unlocking block 14 has a first working position and a second working position.

[0059] In the first working position, there is a gap 142 between the unlocking block 14 and the boss 121 along the first direction. This allows the tip formed by the second inclined surface 111 on the pull block 11 to extend into the gap 142 between the unlocking block 14 and the boss 121 after the pull block 11 slides along the first direction to disengage from the boss 121. This allows the boss 121 to stop the pull block 11 in the first direction when the pull block 11 is reset from the unlocked position to the initial position. The pull block 11 can then drive the locking rod 12 to move and retract into the housing 1.

[0060] When the pull block 11 slides from the initial position to the locked position, the boss 121 is still located on the side of the pull block 11 away from the through hole 191 along the first direction. The end of the unlocking block 14 facing the boss 121 can slide along the second inclined surface 111 and push against the pull block 11 while sliding towards the side away from the unlocking block 14 in a direction perpendicular to the first direction. That is, the end of the unlocking block 14 facing the boss 121 can push against the pull block 11 while sliding towards the side away from the unlocking block 14 in the second direction. Similarly, under the action of the second reset member 132, when the end of the unlocking block 14 facing the boss 121 is disengaged from the second inclined surface 111, the pull block 11 resets in a direction perpendicular to the first direction. That is, the pull block 11 resets in the second direction. Thus, when the pull block 11 slides from the initial position to the locked position, the pull block 11 abuts against the third inclined surface 141.

[0061] Subsequently, during the process of the pull block 11 resetting from the locked position to the initial position, the pull block 11 can push the unlocking block 14 and slide together until the second working position. In the second working position, the pull block 11 presses against the boss 121, and the third inclined surface 141 connects with the first inclined surface 1211 along the first direction. After that, as the pull block 11 continues to reset to the initial position, the locking rod 12 and the unlocking block 14 move together with the pull block 11 along the first direction.

[0062] However, in this embodiment, the locking rod 12 and the unlocking block 14 are subjected to a force that makes them resist the pushing of the pull block 11, so that the pull block 11 can slide along the third inclined surface 141. That is, while the pull block 11 is reset along the first direction, it slides along the direction perpendicular to the first direction toward the side away from the unlocking block 14 until the pull block 11 crosses the third inclined surface 141 in the first direction and aligns with the first inclined surface 1211. At this time, under the action of the second reset member 132, the pull block 11 is reset along the direction perpendicular to the first direction and presses against the first inclined surface 1211.

[0063] Since the pull block 11 has already passed the third inclined plane 141 and aligned with the first inclined plane 1211, when the pull block 11 continues to reset to the initial position, the boss 121 will no longer stop the boss 121. Thus, the boss 121 can drive the locking rod 12 to reset together, so that the insertion end 124 of the locking rod 12 can extend out of the box body 1 and be inserted into the slot 21 of the box cover 2.

[0064] As described above, the locking structure also includes a third reset member 133. That is, the housing 1 is also provided with a third reset member 133. After the pull block 11 is disengaged from the unlocking block 14, the third reset member 133 can drive the unlocking block 14 to reset to the first working position in the first direction, so that when the pull block 11 slides from the initial position to the unlocking position next time, it can continue to be stopped by the boss 121 in the first direction.

[0065] It is worth noting that in this embodiment, the first reset member 131, the second reset member 132, and the third reset member 133 are all spring structures. Specifically, the first reset member 131 is a first reset spring, the second reset member 132 is a second reset spring, and the third reset member 133 is a third reset spring. The first reset spring is used to drive the locking rod 12 to reset to the position extending out of the box 1 after the pull block 11 avoids the locking rod 12. The second reset spring is used to drive the pull block 11 to reset in a direction perpendicular to the first direction after the pull block 11 disengages from the boss 121 and after the pull block 11 disengages from the unlocking block 14. The third reset spring is used to drive the unlocking block 14 to reset in the first direction to the first working position after the pull block 11 disengages from the unlocking block 14.

[0066] As described above, the first return spring can undergo elastic deformation when the pull block 11 moves together with the locking rod 12, and the third return spring can undergo elastic deformation when the pull block 11 moves together with the unlocking block 14, thereby applying forces to the locking rod 12 and the unlocking block 14 respectively to resist the pushing action of the pull block 11.

[0067] Of course, in other alternative embodiments, only one of the first reset member 131 and the third reset member 133 may be set as a spring structure, while the other may be set as another reset structure in the prior art. This embodiment does not impose specific limitations on this.

[0068] Furthermore, based on the above, in this embodiment, the locking rod 12 extends along the first direction, and the unlocking block 14 is sleeved on the outer periphery of the locking rod 12. The locking rod 12 can guide the movement of the unlocking block 14, thereby ensuring that the third inclined surface 141 can accurately connect with the first inclined surface 1211 along the first direction, and thus ensuring that the pull block 11 can accurately pass over the unlocking block 14 and align with the first inclined surface 1211.

[0069] Furthermore, the unlocking block 14 has a first protrusion 143 protruding on the side facing the boss 121, and the boss 121 has a first receiving groove 1212 on the side facing the unlocking block 14. The first protrusion 143 can be embedded in the first receiving groove 1212 when the unlocking block 14 presses against the boss 121, thereby further ensuring that the third inclined surface 141 can accurately connect with the first inclined surface 1211 along the first direction, and further ensuring that the pull block 11 can accurately pass over the unlocking block 14 and align with the first inclined surface 1211.

[0070] Furthermore, the boss 121 has a second protrusion 1213 protruding on the side facing the unlocking block 14, and the unlocking block 14 has a second receiving groove 144 on the side facing the boss 121. The second protrusion 1213 can be embedded in the second receiving groove 144 when the unlocking block 14 presses against the boss 121, thereby further ensuring that the third inclined surface 141 can accurately connect with the first inclined surface 1211 along the first direction, and further ensuring that the pull block 11 can accurately pass over the unlocking block 14 and align with the first inclined surface 1211.

[0071] Of course, in other alternative embodiments, the first protrusion 143 may be provided only on the side of the unlocking block 14 facing the boss 121, and correspondingly, the first receiving groove 1212 may be provided only on the side of the boss 121 facing the unlocking block 14. Alternatively, the second protrusion 1213 may be provided only on the side of the boss 121 facing the unlocking block 14, and correspondingly, the second receiving groove 144 may be provided only on the side of the unlocking block 14 facing the boss 121. This embodiment does not impose specific limitations on this.

[0072] In addition, in this embodiment, the outer periphery of the locking rod 12 is provided with a protrusion 122, and the box body 1 is provided with a first sliding groove 15 extending along the first direction. The protrusion 122 is slidably installed in the first sliding groove 15. The first sliding groove 15 can provide a guiding effect for the locking rod 12 to move along the first direction, thereby ensuring that the locking rod 12 can be accurately inserted into the slot 21.

[0073] Furthermore, when the locking rod 12 extends out of the housing 1 and is inserted into the slot 21, the protrusion 122 can press against the groove wall of the first slide groove 15 in the first direction, thereby ensuring that when the pull block 11 slides from the initial position to the unlocked position, the pull block 11 will not push the locking rod 12 to move. That is, this embodiment can ensure that the first inclined surface 1211 can push against the pull block 11 and slide in a direction perpendicular to the first direction toward the side away from the protrusion 121.

[0074] Based on the above description, it is worth noting that the first return spring is sleeved on the outer periphery of the locking rod 12 and is located between the side wall of the first slide groove 15 away from the through hole 191 and the protrusion 122 along the first direction. When the locking rod 12 moves along the first direction to retract into the box 1, the first return spring is squeezed and deformed. The first return spring can recover its deformation when the pull block 11 does not stop the protrusion 121, thereby causing the locking rod 12 to return to its original position and extend out of the box 1.

[0075] Furthermore, in this embodiment, the locking structure also includes a button 16, that is, the housing 1 is also provided with a button 16, the button 16 is slidably installed in the housing 1 along the first direction, and one end of the button 16 extends out of the housing 1, while the pull block 11 slides in the housing 1 along a direction perpendicular to the first direction, and one end of the button 16 extends out of the housing 1, and the pull block 11 slides on the button 16 along a direction perpendicular to the first direction.

[0076] In addition to button 16, the locking structure also includes a fourth reset member 134, that is, the housing 1 is also provided with a fourth reset member 134. For example, the fourth reset member 134 is a fourth reset spring. The fourth reset member 134 can drive button 16 to drive pull block 11 to reset from the unlock position or the locked position to the initial position.

[0077] Therefore, in this embodiment, the user can press button 16 to slide the pull block 11 to the unlock position or the lock position. Moreover, after the user releases the press of button 16, button 16 can be reset, thereby driving the pull block 11 to reset from the unlock position or the lock position to the initial position, thus making it convenient for the user to unlock or lock the lid 2 and the box body 1.

[0078] For example, in this embodiment, a mounting platform 19 is provided on the top of the box body 1, and a cavity 192 is provided inside the mounting platform 19. The button 16, the locking rod 12, and the unlocking block 14 are all installed in the cavity 192. The button 16 extends out of the mounting platform 19 from one side along the first direction, and a through hole 191 is provided on the other side of the mounting platform 19 along the first direction. The locking rod 12 can extend out of the box body 1 through the through hole 191. After the box cover 2 is placed on the top of the box body 1, the box cover 2 covers the mounting platform 19, and the slot 21 is directly opposite the through hole 191. Thus, the part of the locking rod 12 that extends out of the box body 1 through the through hole 191 can be inserted into the slot 21.

[0079] Therefore, in this embodiment, the mounting platform 19 is provided with an abutment seat 193. When the unlocking block 14 is in the first working position, the side of the unlocking block 14 away from the boss 121 abuts against the abutment seat 193, thereby ensuring that the end of the unlocking block 14 facing the boss 121 can push the pull block 11 to slide in the second direction toward the side away from the unlocking block 14.

[0080] Furthermore, based on the foregoing, the unlocking block 14 has a first groove 145 on the side facing the abutment seat 193, and the abutment seat 193 has a second groove 1931 on the side facing the unlocking block 14. The first groove 145 and the second groove 1931 together form a third receiving groove. The third return spring is sleeved on the outer periphery of the locking rod 12 and installed in the third receiving groove. The two ends of the third return spring are respectively connected to the unlocking block 14 and the abutment seat 193. Thus, when the pull block 11 pushes the unlocking block 14 to move in the first direction, the third return spring is stretched and deformed. The third return spring can recover its deformation after the pull block 11 is separated from the third inclined surface 141, thereby causing the unlocking block 14 to return to the first working position in the first direction.

[0081] Additionally, it should be noted that the button 16 is provided with a second slide groove 161, and all pull blocks 11 are correspondingly provided with a second slide groove 161. The second slide groove 161 extends in a direction perpendicular to the first direction. The pull block 11 is slidably installed in the second slide groove 161. The second return spring is provided in the second slide groove 161 and is located between the side wall of the second slide groove 161 away from the locking rod 12 in a direction perpendicular to the first direction and the pull block 11. When the pull block 11 moves away from the boss 121 or the unlocking block 14 in a direction perpendicular to the first direction, the second return spring is compressed and deformed. The second return spring can recover its deformation when the pull block 11 is facing the first inclined surface 1211 or the third inclined surface 141, thereby driving the pull block 11 to return to its original position.

[0082] Furthermore, the fourth reset spring is disposed in the cavity 192 of the mounting platform 19, and the fourth reset spring is sleeved on the outer periphery of the abutment seat 193. The fourth reset spring is disposed between the button 16 and the cavity wall of the cavity 192, and can be squeezed and deformed when the button 16 slides toward the through hole 191 to drive the pull block 11 to move from the initial position to the unlock position or the locked position, so as to restore the deformation after the user releases the press, thereby driving the button 16 to drive the pull block 11 to reset from the unlock position or the locked position to the initial position.

[0083] In summary, as Figures 5 to 13 As shown, when the lid 2 and body 1 are locked, button 16 and pull block 11 are both fitted around the outer periphery of boss 121. The insertion end 124 of locking rod 12 passes through through hole 191 and is inserted into slot 21. When the user needs to unlock the lid 2 and body 1, the user only needs to press button 16, so that button 16 drives pull block 11 to move from the initial position to the unlocked position along the first direction. During this process, pull block 11 slides along the first inclined surface 1211 via the second inclined surface 111. When pull block 11 moves... When the device reaches the unlock position, the second inclined surface 111 disengages from the first inclined surface 1211, and the second reset component 132 resets the pull block 11, causing the pull block 11 to move between the boss 121 and the unlock block 14. After that, the user releases the pressure, and the fourth reset component 134 drives the button 16 to reset. The button 16 drives the pull block 11 to reset to the initial position. At the same time, the pull block 11 pushes against the boss 121 and moves the locking rod 12 together, thereby causing the locking rod 12 to retract into the box body 1, thus unlocking the box cover 2 and the box body 1.

[0084] After the user closes the lid 2, the user presses button 16, causing button 16 to move pull block 11 from the initial position to the locked position along the first direction. It is understood that the travel distance of button 16 during this press is greater than the travel distance of button 16 when the user unlocks the lid 2 and the box body 1. During the process of the user pressing button 16 to move pull block 11 from the initial position to the locked position along the first direction, the locking lever 12 is reset by the first return spring, while pull block 11 is pushed by unlocking block 14 and moves in a direction perpendicular to the first direction until the second inclined surface 111 passes the end of unlocking block 14 facing the boss 121. Afterward, pull block 11 faces the third inclined surface 141. As pull block 11 continues to move towards the locked position, the second reset component 132 drives pull block 11 to gradually reset. When pull block 11 reaches the locked position, the user releases button 16, and the fourth reset component 1... 34 Drive button 16 to reset. Button 16 drives pull block 11 to reset to the initial position. During this process, pull block 11 pushes against unlocking block 14. Unlocking block 14 moves from the first working position to the second working position and subsequently drives boss 121 to move together. At the same time, under the action of the first reset spring and the third reset spring, pull block 11 will slide along the third inclined surface 141 until it crosses the third inclined surface 141 and is directly opposite the first inclined surface 1211. As pull block 11 continues to move to the initial position, the second reset member 132 drives pull block 11 to gradually reset. Pull block 11 keeps pressing against the first inclined surface 1211.

[0085] When the pull block 11 passes the third inclined plane 141 and is directly opposite the first inclined plane 1211, the locking rod 12 is reset and extends out of the box body 1 under the action of the first reset member 131, thereby locking the box cover 2 and the box body 1, while the unlocking block 14 is reset to press against the abutment seat 193 again under the action of the third reset member 133.

[0086] Furthermore, it is worth noting that in this embodiment, when the pull block 11 slides to the unlock position, the end face of the button 16 extending from one end of the box body 1 is flush with the outer surface of the box body 1, thereby providing an indication function for the user. That is, when the user needs to unlock the box cover 2 and the box body 1, the user only needs to press the button 16 until the end face of the button 16 extending from one end of the box body 1 is flush with the outer surface of the box body 1. When the user closes the box cover 2, the user needs to press the button 16 until the button 16 moves into the box body 1.

[0087] Additionally, please see Figures 2 to 4 Based on the foregoing, it should be noted that in this embodiment, the lid 2 is rotatably connected to the body 1 via a pivot 17. A torsion spring 171 is sleeved on the pivot 17 and installed between the lid 2 and the body 1. The torsion spring 171 can drive the lid 2 to open after the locking rod 12 retracts into the body 1. That is, when the user presses the button 16 to unlock the lid 2 and the body 1, the lid 2 can open automatically, thus facilitating user operation.
