[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] like Figures 1-4As shown, this embodiment provides a storage box, which includes a shell 1 and a lid 2 that can be opened and closed relative to each other. The shell 1 is equipped with a switch assembly; when the storage box is closed, the switch assembly is connected to the lid 2; when the storage box is opened, the switch assembly is disconnected from the lid 2. Specifically, when the storage box is closed, the switch assembly connects to the lid 2, locking the lid 2. Through mechanical locking, the storage box can remain closed even during violent shaking or accidental collisions, improving safety. When the storage box needs to be opened, the switch assembly disconnects from the lid 2, allowing the lid 2 to rotate relative to the shell 1 and open. This embodiment solves the problem that the lid 2 may accidentally detach from the shell 1 during violent shaking or accidental collisions, improving the reliability and safety of the storage box. In this embodiment, the storage box can be a wireless Bluetooth headset charging case.

[0038] Preferably, the cover 2 has a protrusion 21; the switch assembly includes a stop 3 slidably connected to the housing 1 and a drive mechanism 4 disposed on the housing 1. The drive mechanism 4 is configured to drive the stop 3 to move between a stop position and a clearance position. The stop 3 in the stop position can connect to the protrusion 21, and the stop 3 in the clearance position can avoid the protrusion 21. In the closed state, the operator can drive the stop 3 to the stop position through the drive mechanism 4. At this time, the stop 3 stops the protrusion 21, thereby locking the cover 2. Through mechanical locking, the storage box can still maintain the closed state in the event of violent shaking or accidental collision, improving safety. When it is necessary to go from the closed state to the open state, the operator can drive the stop 3 to the clearance position through the drive mechanism 4. At this time, the stop 3 avoids the protrusion 21, and the cover 2 can rotate relative to the housing 1 to complete the lifting action.

[0039] In this embodiment, the cover 2 and the housing 1 are hinged, and a torsion spring 12 is provided at the hinge point. The torsion spring 12 provides a force for lifting the cover 2. When the cover is closed, when the stop 3 moves from the stop position to the clearance position, the locking state of the cover 2 is released, and the torsion spring 12 can automatically drive the cover 2 to lift, improving the user experience. Specifically, the housing 1 includes an outer shell 11 and a hinge shaft 13. The hinge shaft 13 is disposed on the outer shell 11, the cover 2 is hinged to the hinge shaft 13, and the torsion spring 12 is sleeved on the hinge shaft 13.

[0040] Optionally, the drive mechanism 4 includes a first gear 41 and a drive component 43. The first gear 41 is rotatably connected to the housing 1, and the drive component 43 drives the first gear 41 to rotate. The stop member 3 has a toothed section 31 on the side near the first gear 41, and the first gear 41 meshes with the toothed section 31. When the drive component 43 drives the first gear 41 to rotate, the first gear 41 meshes with the toothed section 31 of the stop member 3, thereby driving the stop member 3 to slide within the housing 1.

[0041] When the stop 3 needs to switch between the stop position and the clearance position, the first gear 41 needs to rotate clockwise or counterclockwise according to the position of the stop 3. If the rotation direction of the first gear 41 is incorrect, the stop 3 will continue to move in the opposite direction, failing to meet the usage requirements. To solve the above problem, at least one end of the toothed segment 31 is provided with a limiting part 32, which is used to stop the tooth groove of the first gear 41. When the rotation direction of the first gear 41 is incorrect, the limiting part 32 can stop the tooth groove of the first gear 41, preventing the first gear 41 from continuing to rotate in the wrong direction. At this time, the operator can drive the first gear 41 to rotate in the opposite direction, improving the reliability of use and preventing jamming. In this embodiment, both ends of the toothed segment 31 are provided with limiting parts 32, and the limiting parts 32 are higher than the height of the teeth of the toothed segment 31, so as to achieve the purpose of locking the first gear 41.

[0042] In this embodiment, as Figures 3-6 As shown, the driving component 43 includes a driving rod 431 and a second gear 432 disposed on the driving rod 431. One end of the driving rod 431 is rotatably connected to the housing 1 and the other end extends out of the housing 1. The second gear 432 is meshed with the first gear 41. The operator can manually rotate the driving rod 431 to drive the second gear 432 to rotate. The second gear 432 drives the first gear 41 to rotate, and the first gear 41 drives the stop 3 to slide within the housing 1.

[0043] Preferably, the outer contour of the second gear 432 is provided with a first empty section 4321. When the first empty section 4321 is directly opposite the first gear 41, a gap is provided between the first empty section 4321 and the first gear 41. When the second gear 432 is driven to rotate, the stop member 3 moves. When the stop member 3 moves to a preset position, the first empty section 4321 is directly opposite the first gear 41, providing tactile feedback to the operator, indicating that the stop member 3 has moved to the preset position.

[0044] Furthermore, the drive component 43 also includes an annular seat 433, which is rotatably connected to the housing 1. The annular seat 433 is provided with an annular toothed groove 4331, and the first gear 41 is meshed with the annular toothed groove 4331. The operator can manually rotate the annular seat 433, and the annular toothed groove 4331 drives the first gear 41 to rotate, and the first gear 41 drives the stop 3 to slide within the housing 1.

[0045] In this embodiment, the driving component 43 includes an annular seat 433, a driving rod 431, and a second gear 432. When the annular seat 433 and the second gear 432 rotate in the same direction, the rotation direction of the first gear 41 is opposite. Therefore, when the operator drives the annular seat 433 or the second gear 432 to rotate in the same direction, the stop 3 can be driven to move back and forth between the stop position and the clearance position. The operator does not need to rotate the annular seat 433 or the second gear 432 in the opposite direction, which improves the user experience.

[0046] Preferably, the annular toothed groove 4331 is provided with a second empty section 4332. When the second empty section 4332 is directly opposite the first gear 41, a gap is provided between the second empty section 4332 and the first gear 41. When the driving annular seat 433 rotates, the stop member 3 moves. When the stop member 3 moves to a preset position, the second empty section 4332 is directly opposite the first gear 41, providing tactile feedback to the operator, indicating that the stop member 3 has moved to the preset position.

[0047] It should be noted that when the stop part 3 is in the stop position or the avoidance position, the first idle section 4321 and the second idle section 4332 are both directly opposite the first gear 41, forming a clutch structure. When one of the driving ring seat 433 and the second gear 432 rotates, the other remains stationary, reducing the magnitude of the applied rotational force and improving the user experience.

[0048] In this embodiment, the cover 2 is provided with two spaced-apart protrusions 21, and the stop member 3 is provided with stop portions 33 at both ends, which are used to stop the two protrusions 21. When the stop member 3 is in the stop position, the two stop portions 33 stop the two protrusions 21 respectively, thereby improving the locking strength. Both sides of the two stop portions 33 that are close to each other are provided with clearance openings. When the stop portions 33 are in the clearance position, one of the protrusions 21 can move upward through the clearance openings.

[0049] In this embodiment, a notch 22 is provided on the side of the cover 2 away from the hinge part of the housing 1 and the cover 2. Two protrusions 21 are provided on both sides of the notch 22. The housing 1 also includes a support plate 14, which is connected to the outer shell 11. The support plate 14 is used to support the earphone. The outer shell 11 and the support plate 14 together form a support part 15 that can be embedded in the notch 22. In the closed state, the support part 15 is located in the notch 22. The stop member 3 is slidably connected to the support part 15. The drive mechanism 4 is provided on the support part 15 so that the stop part 33 of the stop member 3 can move to the top of the protrusion 21 to lock the cover 2.

[0050] Furthermore, the support 15 is provided with a receiving cavity 153. Guide holes 154 are provided on two opposing sidewalls of the receiving cavity 153 along a first direction, which is the spacing direction of the two bosses 21. The stop member 3 is slidably connected to the two guide holes 154. The side of the receiving cavity 153 closest to the hinge point between the housing 1 and the cover 2 is the first sidewall 151, located on the support plate 14. The side of the receiving cavity 153 furthest from the hinge point between the housing 1 and the cover 2 is the second sidewall 152, located on the outer shell 11. The annular seat 433 rotates... The drive rod 431 is rotatably connected to the second side wall 152. One end of the drive rod 431 is rotatably connected to the first side wall 151, and the other end extends into the annular seat 433 and is rotatably connected to the end cover 44. The drive mechanism 4 also includes a driven rod 42. The first gear 41 is disposed on the driven rod 42. One end of the driven rod 42 is rotatably connected to the first side wall 151, and the other end extends into the annular seat 433 and is rotatably connected to the end cover 44. The end cover 44 is located inside the annular seat 433. The annular seat 433 can rotate relative to the end cover 44. The end cover 44 can cover the internal structure of the drive mechanism 4 and improve its aesthetics.

[0051] Preferably, one end of the boss 21 is provided with a stop surface 211, and the stop member 3 can stop the stop surface 211. The other end of the boss 21 is provided with a guide slope 212. When the storage box is in the open state, if the stop member 3 is in the stop position, when the lid is closed manually, the stop member 3 can undergo elastic deformation under the action of the guide slope 212, and the boss 21 continues to move downward until the boss 21 moves to the bottom of the stop member 3. At this time, the stop member 3 presses against the stop surface 211, thereby automatically locking the lid 2 and achieving the purpose of automatically locking the lid.

[0052] This embodiment also provides the operation process of the storage box, so as to... Figure 5 and Figure 6 From the perspective shown, rotating the drive rod 431 clockwise causes the second gear 432 to rotate one revolution, which in turn drives the first gear 41 to rotate. The first gear 41 then drives the stop 3 to move to the left, causing the stop 3 to leave the stop position. At this time, the cover 2 will automatically open under the action of the torsion spring 12.

[0053] After rotating clockwise one full turn, the first empty section 4321 of the second gear 432 is now aligned with the first gear 41, and the second gear 432 separates from the first gear 41. At this point, the stop 3 moves to the clearance position. After manually closing the lid, rotating the annular seat 433 clockwise will cause the first gear 41 to rotate in the opposite direction. After the annular seat 433 rotates half a full turn, the second empty section 4332 of the annular seat 433 is now aligned with the first gear 41, and the annular tooth groove 4331 separates from the first gear 41. At this point, the stop 3 moves to the stop position, locking the lid 2. This embodiment allows the operator to drive the annular seat 433 or the second gear 432 in the same direction when the storage box is in the closed or open state, causing the stop 3 to move between the stop position and the clearance position. This avoids the need to drive the rotation in two opposite directions when opening or closing the lid, improving the user experience.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
