[0042] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings, rather than all the structures.

[0043] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components.

[0045] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", "left", etc. are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for differentiation in description and have no special meaning.

[0046] Please refer to Figures 1 to 4 , this embodiment provides a headphone case. The headphone case includes a case body 1 and a case cover 2. Among them, the case body 1 is provided with a receiving groove 18 for receiving the wireless headphones 100. The case cover 2 has an open state and a closed state. The case cover 2 in the open state can expose the receiving groove 18 to facilitate the user to take out and then receive the wireless headphones 100. The case cover 2 in the closed state can close the receiving groove 18 to store the wireless headphones 100.

[0047] Based on the above, in combination with Figures 5 to 13 , in this embodiment, the case body 1 is provided with a locking structure. The locking structure includes a pulling block 11, a locking rod 12 and a first reset member 131. That is, the case body 1 is provided with a pulling block 11, a locking rod 12 and a first reset member 131. Both the pulling block 11 and the locking rod 12 are slidably connected to the case body 1 along a first direction. The pulling block 11 can slide relative to the case body 1 from an initial position to an unlocking position or a locking position along the first direction. And during the process of the pulling block 11 resetting from the unlocking position to the initial position, the locking rod 12 stops the pulling block 11. The pulling block 11 can pull the locking rod 12 to retract into the interior of the case body 1. During the process of the pulling block 11 resetting from the locking position to the initial position, the pulling block 11 avoids the locking rod 12, and the first reset member 131 can drive the locking rod 12 to reset to extend out of the case body 1.

[0048] The case cover 2 is provided with a slot 21. The case cover 2 can be buckled on the top of the case body 1. The part of the locking rod 12 extending out of the case body 1 is inserted into the slot 21 to lock the case cover 2 and the case body 1, thereby preventing the case cover 2 from being accidentally opened due to the shaking of the headphone case.

[0049] As described above, in this embodiment, the pulling block 11 can alternately slide from the initial position to the unlocking position and from the initial position to the locking position. Among them, after the pulling block 11 slides from the initial position to the unlocking position, the pulling block 11 resets from the unlocking position to the initial position, and during the reset process, the locking rod 12 is pulled to retract into the interior of the box body 1, so as to unlock the box cover 2 and the box body 1, and further enable the user to open the box cover 2 to take out the wireless earphone 100 or put the wireless earphone 100 into the box body 1. After the pulling block 11 slides from the initial position to the locking position, the pulling block 11 resets from the locking position to the initial position, and during the reset process, the locking rod 12 is avoided, so that the locking rod 12 can reset to extend out of the box body 1 and insert into the box cover 2, and further lock the box cover 2 and the box body 1 to prevent the wireless earphone 100 from falling out of the earphone box due to accidental opening of the box cover 2, thereby improving the user experience.

[0050] Specifically, after the pulling block 11 slides from the initial position to the unlocking position, during the process of the pulling block 11 resetting to the initial position, the locking rod 12 stops the pulling block 11, so that the pulling block 11 can pull the locking rod 12 to retract into the interior of the box body 1, and further unlock the box cover 2 and the box body 1. The pulling block 11 reset to the initial position can slide to the locking position next time. After that, during the process of the pulling block 11 resetting to the initial position, the stop of the locking rod 12 on the pulling block 11 is released, so that the locking rod 12 can reset to extend out of the box body 1 and insert into the box cover 2, and further lock the box cover 2 and the box body 1. Moreover, after the pulling block 11 slides from the initial position to the unlocking position next time, it can continue to pull the locking rod 12 to retract into the interior of the box body 1 during the process of resetting to the initial position.

[0051] Based on the content described above, in this embodiment, the pulling block 11 can also slide relative to the box body 1 in a direction perpendicular to the first direction. One end of the locking rod 12 is provided with a convex platform 121, and the convex platform 121 is provided with a first inclined surface 1211. When the pulling block 11 slides from the initial position to the unlocking position, the first inclined surface 1211 can push against the pulling block 11 and slide in a direction away from the convex platform 121 along a direction perpendicular to the first direction at the same time.

[0052] Specifically, in this embodiment, one end of the locking rod 12 is used as the stop end 123 and the other end is used as the insertion end 124 for description. A through hole 191 is provided on the box body 1, and the insertion end 124 can pass through the through hole 191 and extend out of the box body 1, so as to insert into the box cover 2.

[0053] Along the first direction, from the end far away from the insertion end 124 to the end close to the insertion end 124, the first inclined surface 1211 gradually inclines away from the locking rod 12. Thus, the pulling block 11 can slide along the first inclined surface 1211 when sliding from the initial position to the unlocking position, and the first inclined surface 1211 can push against the pulling block 11 and slide in a direction away from the convex platform 121 along a direction perpendicular to the first direction at the same time.

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

[0055] Exemplarily, in this embodiment, the boss 121 has a frustum structure, and the diameter of the boss 121 gradually increases from the side away from the insertion end 124 to the side close to the insertion end 124. Thus, the side surface of the frustum forms the first inclined surface 1211. Correspondingly, in this embodiment, two pulling blocks 11 are provided. The two pulling blocks 11 are oppositely arranged in a direction perpendicular to the first direction. In this embodiment, it is described that the two pulling blocks 11 are oppositely arranged in the second direction. The two pulling blocks 11 are respectively arranged on both sides of the lock rod 12 in the second direction. Thus, when the pulling block 11 moves along the first direction toward the side close to the through hole 191, that is, when the pulling block 11 slides from the initial position to the unlocking position along the first direction, the pulling block 11 slides along the first inclined surface 1211, so that while the pulling block 11 moves along the first direction, it also slides along the second direction toward the side away from the boss 121. After the pulling block 11 slides along the first direction to disengage from the boss 121, the boss 121 releases the stop on the pulling block 11. Under the action of the second reset member 132, the pulling block 11 moves along the second direction toward the side close to the lock rod 12, so that it can overlap with the boss 121 along the first direction. That is, the boss 121 stops on the side of the pulling block 11 away from the through hole 191 along the first direction. Subsequently, when the pulling block 11 resets from the unlocking position to the initial position, the pulling block 11 can push against the boss 121, thereby driving the lock rod 12 to move together, and further causing the lock rod 12 to retract into the box body 1.

[0056] It can be understood that in other alternative embodiments, the locking structure may also be provided with only one pulling block 11, or the locking structure may be provided with more than three pulling blocks 11 along the circumferential direction of the boss 121. Correspondingly, all the pulling blocks 11 can slide radially corresponding to the boss 121. This embodiment does not make specific limitations on this.

[0057] It can also be understood that in other optional embodiments, the first inclined surface 1211 can also be a planar structure arranged on the side of the boss 121, and the pull block 11 is arranged corresponding 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. In the process of the pull block 11 sliding from the initial position to the unlocking 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 toward the side away from the locking rod 12, and an unlocking block 14 is provided between the other end of the locking rod 12 and the boss 121, that is, an unlocking block 14 is provided between the insertion end 124 of the locking rod 12 and the boss 121, and the unlocking block 14 is provided with a third inclined surface 141. The inclination direction of the third inclined surface 141 is opposite to that of the first inclined surface 1211, and the unlocking block 14 has a first working position and a second working position.

[0059] Among them, in the first working position, there is a gap 142 between the unlocking block 14 and the boss 121 along the first direction, so that when the pull block 11 slides along the first direction to disengage from the boss 121, the tip formed by the second inclined surface 111 on the pull block 11 can extend into the gap 142 between the unlocking block 14 and the boss 121, so that when the pull block 11 is reset from the unlocking position to the initial position, the boss 121 stops the pull block 11 in the first direction, and the pull block 11 can drive the locking rod 12 to move to retract into the box body 1.

[0060] When the pull block 11 slides from the initial position to the locking position, at this time, the boss 121 is still located on the side of the pull block 11 away from the through hole 191 along the first direction, and the end of the unlocking block 14 toward the boss 121 can slide along the second inclined surface 111, and push the pull block 11 while sliding along the direction perpendicular to the first direction toward the side away from the unlocking block 14, that is, the end of the unlocking block 14 toward the boss 121 can push the pull block 11 while sliding along the second direction toward the side away from the unlocking block 14. Similarly, under the action of the second reset member 132, when the end of the unlocking block 14 toward the boss 121 is disengaged from the second inclined surface 111, the pull block 11 is reset along the direction perpendicular to the first direction, that is, the pull block 11 is reset along the second direction. Therefore, when the pull block 11 slides from the initial position to the locking position, the pull block 11 abuts against the third inclined surface 141.

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

[0062] However, in this embodiment, the locking rod 12 and the unlocking block 14 are subjected to a force that resists the push 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 also slides along a direction perpendicular to the first direction toward the side away from the unlocking block 14 until the pull block 11 passes over the third inclined surface 141 in the first direction and is aligned 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 a direction perpendicular to the first direction and pressed against the first inclined surface 1211.

[0063] Since the pull block 11 has passed the third inclined surface 141 and is aligned with the first inclined surface 1211, when the pull block 11 continues to reset to the initial position, the boss 121 will no longer stop the boss 121. As a result, 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] From the above, the locking structure also includes a third reset member 133, that is, the box body 1 is also provided with a third reset member 133. The third reset member 133 can drive the unlocking block 14 to reset to the first working position along the first direction after the pull block 11 is disengaged from the unlocking block 14, so that the pull block 11 can continue to be stopped by the boss 121 in the first direction when it slides from the initial position to the unlocking position next time.

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

[0066] As described above, when the pulling block 11 drives the locking rod 12 to move together, the first return spring can undergo elastic deformation, and when the pulling block 11 drives the unlocking block 14 to move together, the third return spring can undergo elastic deformation, thereby applying forces to the locking rod 12 and the unlocking block 14 respectively to resist the pushing of the pulling 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, and the other may be set as other reset structures in the prior art. This embodiment does not make specific limitations on this.

[0068] In addition, based on the above, in this embodiment, the locking rod 12 extends in the first direction, the unlocking block 14 is sleeved on the outer periphery of the locking rod 12, and the locking rod 12 can guide the movement of the unlocking block 14, so as to ensure that the third inclined surface 141 can be accurately connected with the first inclined surface 1211 along the first direction, and further ensure that the pulling block 11 can accurately cross the unlocking block 14 and align with the first inclined surface 1211.

[0069] Furthermore, a first protruding portion 143 protrudes from the side of the unlocking block 14 facing the boss 121, and a first receiving groove 1212 is provided on the side of the boss 121 facing the unlocking block 14. The first protruding portion 143 can be embedded in the first receiving groove 1212 when the unlocking block 14 presses against the boss 121, so as to further ensure that the third inclined surface 141 can be accurately connected with the first inclined surface 1211 along the first direction, and further ensure that the pulling block 11 can accurately cross the unlocking block 14 and align with the first inclined surface 1211.

[0070] Moreover, a second protruding portion 1213 protrudes from the side of the boss 121 facing the unlocking block 14, and a second receiving groove 144 is provided on the side of the unlocking block 14 facing the boss 121. The second protruding portion 1213 can be embedded in the second receiving groove 144 when the unlocking block 14 presses against the boss 121, so as to further ensure that the third inclined surface 141 can be accurately connected with the first inclined surface 1211 along the first direction, and further ensure that the pulling block 11 can accurately cross the unlocking block 14 and align with the first inclined surface 1211.

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

[0072] In addition, in this embodiment, a convex block 122 is provided on the outer periphery of the lock rod 12, and the box body 1 is provided with a first sliding groove 15 extending in the first direction. The convex block 122 is slidably installed in the first sliding groove 15. The first sliding groove 15 can provide a guiding function for the movement of the lock rod 12 in the first direction, so as to ensure that the lock rod 12 can be accurately inserted into the slot 21.

[0073] Moreover, when the convex block 122 extends out of the box body 1 and is inserted into the slot 21, the convex block 122 can be pressed against the groove wall of the first sliding groove 15 in the first direction, so as to ensure that when the pulling block 11 slides from the initial position to the unlocking position, the pulling block 11 will not push the lock rod 12 to move. That is, this embodiment can ensure that the first inclined surface 1211 can push the pulling block 11 and slide along a direction perpendicular to the first direction toward the side away from the convex platform 121.

[0074] Based on the foregoing, it is worth noting that the first return spring is sleeved on the outer periphery of the lock rod 12 and is arranged between the groove wall of the first sliding groove 15 along the first direction away from the through hole 191 and the convex block 122. When the lock rod 12 moves in the first direction to retract into the box body 1, the first return spring is squeezed and deformed. The first return spring can restore the deformation when the pulling block 11 does not block the convex platform 121, so that the lock rod 12 is reset to extend out of the box body 1.

[0075] Furthermore, in this embodiment, the locking structure further includes a button 16. That is, the box body 1 is further provided with a button 16. The button 16 is slidably installed in the box body 1 along the first direction, and one end of the button 16 extends out of the box body 1. The pulling block 11 slides in the box body 1 along a direction perpendicular to the first direction, and one end of the button 16 extends out of the box body 1. The pulling block 11 slides on the button 16 along a direction perpendicular to the first direction.

[0076] In addition to the button 16, the locking structure further includes a fourth reset member 134. That is, the box body 1 is further provided with a fourth reset member 134. Exemplarily, the fourth reset member 134 is a fourth return spring. The fourth reset member 134 can drive the button 16 to drive the pulling block 11 to reset from the unlocking position or the locking position to the initial position.

[0077] As described above, in this embodiment, the user can press the button 16 to drive the pulling block 11 to slide to the unlocking position or the locking position. Moreover, after the user releases the button 16, the button 16 can be reset, so as to drive the pulling block 11 to reset from the unlocking position or the locking position to the initial position, thus facilitating the user to unlock or lock the box cover 2 and the box body 1.

[0078] Exemplarily, in the present embodiment, a mounting platform 19 is provided at the top of the box body 1. 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. Among them, the button 16 extends out of the mounting platform 19 from one side of the mounting platform 19 along the first direction. A through hole 191 is provided on the other side of the mounting platform 19 along the first direction. The locking rod 12 can pass through the through hole 191 and extend out of the box body 1. After the box cover 2 is buckled on the top of the box body 1, the box cover 2 covers the mounting platform 19, and the slot 21 is aligned with the through hole 191. Thus, the portion 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] From the above, in the present embodiment, an abutting seat 193 is provided inside the mounting platform 19. 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 abutting seat 193, so as to ensure that one end of the unlocking block 14 facing the boss 121 can push the pulling block 11 to slide along the second direction toward the side away from the unlocking block 14.

[0080] Moreover, based on the foregoing, a first groove portion 145 is provided on the side of the unlocking block 14 facing the abutting seat 193, and a second groove portion 1931 is provided on the side of the abutting seat 193 facing the unlocking block 14. The first groove portion 145 and the second groove portion 1931 together form a third accommodating groove. The third return spring is sleeved on the outer periphery of the locking rod 12 and installed in the third accommodating groove, and both ends of the third return spring are respectively connected to the unlocking block 14 and the abutting seat 193. Thus, when the pulling block 11 pushes the unlocking block 14 to move along the first direction, the third return spring is stretched and deformed. The third return spring can recover the deformation after the pulling block 11 separates from the third inclined surface 141, so that the unlocking block 14 is reset to the first working position along the first direction.

[0081] In addition, it should be noted that a second sliding groove 161 is provided on the button 16, and all the pulling blocks 11 are correspondingly provided with a second sliding groove 161. The second sliding groove 161 extends along a direction perpendicular to the first direction. The pulling block 11 is slidably installed in the second sliding groove 161. The second return spring is provided in the second sliding groove 161 and between the groove wall on the side of the second sliding groove 161 away from the locking rod 12 along the direction perpendicular to the first direction and the pulling block 11. When the pulling block 11 moves along the direction perpendicular to the first direction away from the boss 121 or the unlocking block 14, the second return spring is squeezed and deformed. The second return spring can recover the deformation when the pulling block 11 is aligned with the first inclined surface 1211 or the third inclined surface 141, so as to drive the pulling block 11 to reset.

[0082] Further, the fourth return spring is disposed in the cavity 192 of the mounting table 19, and the fourth return spring is sleeved on the outer periphery of the abutting seat 193. The fourth return spring is disposed between the button 16 and the wall of the cavity 192, and can be deformed by being squeezed when the button 16 slides toward the through hole 191 to drive the pulling block 11 to move from the initial position to the unlocking position or the locking position. Thus, after the user releases the pressing, the deformation is restored to drive the button 16 to drive the pulling block 11 to reset from the unlocking position or the locking position to the initial position.

[0083] In summary, as Figures 5 to 13 shown, when the lid 2 and the box body 1 are in the locked state, the button 16 and the pulling block 11 are both sleeved on the outer periphery of the boss 121. The insertion end 124 of the locking rod 12 passes through the through hole 191 and is inserted into the slot 21. When the user needs to unlock the lid 2 and the box body 1, the user only needs to press the button 16 to make the button 16 drive the pulling block 11 to move from the initial position to the unlocking position along the first direction. During this process, the pulling block 11 slides along the first inclined surface 1211 through the second inclined surface 111. When the pulling block 11 moves to the unlocking position, the second inclined surface 111 disengages from the first inclined surface 1211, and the second restoring member 132 resets the pulling block 11 to make the pulling block 11 move between the boss 121 and the unlocking block 14. After that, the user releases the pressing, and the fourth restoring member 134 drives the button 16 to reset. The button 16 drives the pulling block 11 to reset to the initial position. At the same time, the pulling block 11 pushes against the boss 121 and drives the locking rod 12 to move together, so that the locking rod 12 retracts into the box body 1, and then the lid 2 and the box body 1 are unlocked.

[0084] After the user closes the lid 2, the user presses the button 16 so that the button 16 drives the pulling block 11 to move from the initial position to the locking position along the first direction. It can be understood that the travel of pressing the button 16 this time is greater than the travel of pressing the button 16 when the user unlocks the lid 2 and the box body 1. During the process that the user presses the button 16 so that the button 16 drives the pulling block 11 to move from the initial position to the locking position along the first direction, the locking rod 12 is reset under the action of the first return spring, while the pulling block 11 is pushed by the unlocking block 14 to move along the direction perpendicular to the first direction until the second inclined surface 111 passes over one end of the unlocking block 14 facing the boss 121. After that, the pulling block 11 faces the third inclined surface 141. As the pulling block 11 continues to move towards the locking position, the second reset member 132 drives the pulling block 11 to gradually reset. When the pulling block 11 moves to the locking position, the user releases the pressing of the button 16, and the fourth reset member 134 drives the button 16 to reset, and the button 16 drives the pulling block 11 to reset to the initial position. During this process, the pulling block 11 pushes against the unlocking block 14, and the unlocking block 14 moves from the first working position to the second working position and drives the boss 121 to move together subsequently. At the same time, under the action of the first return spring and the third return spring, the pulling block 11 slides along the third inclined surface 141 until it passes over the third inclined surface 141 and faces the first inclined surface 1211. As the pulling block 11 continues to move towards the initial position, the second reset member 132 drives the pulling block 11 to gradually reset, and the pulling block 11 keeps pressing against the first inclined surface 1211.

[0085] When the pulling block 11 passes over the third inclined surface 141 and faces the first inclined surface 1211, the locking rod 12 is reset under the action of the first reset member 131 and extends out of the box body 1, thereby locking the lid 2 and the box body 1, while the unlocking block 14 is reset under the action of the third reset member 133 to press against the abutting seat 193 again.

[0086] Moreover, it is worth noting that in this embodiment, when the pulling block 11 slides to the unlocking position, the end face of the button 16 extending out of the box body 1 is flush with the outer surface of the box body 1, so as to provide an indication function for the user. That is, when the user needs to unlock the lid 2 and the box body 1, the user only needs to press the button 16 until the end face of the button 16 extending out of the box body 1 is flush with the outer surface of the box body 1. And when the user closes the lid 2, the user needs to press the button 16 until the button 16 moves into the interior of the box body 1.

[0087] In addition, please refer to Figures 2 to 4 , based on the content described above, it should be noted that in this embodiment, the lid 2 is rotatably connected to the box body 1 through a rotating shaft 17. A torsion spring 171 is sleeved on the rotating shaft 17, and the torsion spring 171 is installed between the lid 2 and the box body 1. The torsion spring 171 can drive the lid 2 to open after the locking rod 12 retracts into the interior of the box body 1. That is, when the user presses the button 16 to unlock the lid 2 and the box body 1, the lid 2 can automatically open, which is convenient for the user to operate.
