Description

Technical Field

[0001] This utility model relates to the field of sound energy conversion technology, and in particular to an earphone storage box and wireless earphones. Background Technology

[0002] Wireless earphones typically include an earphone case and the earphone units stored inside the case. The earphone case serves two purposes: protecting the earphone units and charging them.

[0003] In existing technology, an earphone case includes a body and a lid. The lid is rotatably connected to the body, so that the lid and body cooperate to form an earphone compartment, in which the earphones are located. Besides the rotatable connection, the lid and body are also detachably connected via magnetic attraction to allow the lid to open and close. To improve the ease of use of the earphone case, a torsion spring is usually provided between the body and the lid. The torsion spring always has a tendency to drive the lid to rotate relative to the body, thus opening it. The magnetic connection between the lid and body ensures that the lid will not open when only subjected to the torsion spring. When an external force is manually applied to the lid, the external force and the torsion spring overcome the magnetic attraction, causing the lid to open automatically.

[0004] However, the headphone case may be accidentally bumped during use, causing the lid to open abnormally. Furthermore, the lid may also open unexpectedly when the headphone case is dropped, resulting in the headphone case having weak reliability and drop resistance. Utility Model Content

[0005] The first objective of this invention is to provide an earphone storage box to solve the technical problems of low reliability and poor drop resistance in the prior art.

[0006] The second objective of this invention is to provide a wireless earphone with high drop resistance.

[0007] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0008] The headphone case includes:

[0009] The housing includes an earphone slot and a receiving slot.

[0010] The upper shell has a first sidewall and a second sidewall disposed opposite to each other in a first direction. The first sidewall is rotatably connected to the box body, and the second sidewall is provided with a locking engagement structure.

[0011] An operating component is slidably connected to the housing along the first direction, one end of the operating component is located in the receiving groove, and the operating component is rotatably connected to the housing about an axis extending along the first direction.

[0012] A locking assembly includes a lock cylinder connected to one end of the operating member located within the receiving groove; the lock cylinder has a locked position connected to the locking engagement structure and an unlocked position separated from the locking engagement structure; the operating member slides and rotates relative to the housing to move the lock cylinder from the locked position to the unlocked position.

[0013] In one embodiment, the locking mechanism includes a locking groove, wherein the lock cylinder is located in the locking groove in the locked position, and the lock cylinder is located outside the locking groove in the unlocked position;

[0014] The operating member slides in the first direction to drive the lock cylinder to slide in the locking groove along the first direction; the operating member rotates about an axis extending along the first direction to drive one end of the lock cylinder to rotate out of the locking groove.

[0015] In one embodiment, the locking groove includes a first sliding groove and a notch that are interconnected, and one end of the lock cylinder can slide in the first sliding groove along the first direction;

[0016] The groove wall of the receiving groove is provided with a second sliding groove, and the end of the lock cylinder opposite to the first sliding groove can be slidably disposed in the second sliding groove in a second direction;

[0017] The operating member rotates about an axis extending along the first direction to cause one end of the lock cylinder to separate from the notch, and to cause the other end of the lock cylinder to be located in the second slide groove;

[0018] The second direction is perpendicular to the first direction.

[0019] In one embodiment, the locking assembly further includes a first elastic element disposed in the second groove and extending along the second direction; the other end of the lock cylinder slides in the second groove to compress the first elastic element.

[0020] In one embodiment, the wall of the receiving groove is provided with a third sliding groove; the end of the lock cylinder opposite to the locking groove can be slidably disposed in the third sliding groove along a first direction, and the third sliding groove is connected to one end of the second sliding groove.

[0021] In one embodiment, the locking assembly further includes a top block that contacts one end of the first elastic member, and the end of the lock cylinder opposite to the locking groove can contact the top block;

[0022] The end face of the top block opposite to the first elastic member is flush with or lower than the wall of the third sliding groove.

[0023] In one embodiment, the upper shell has a groove located on one side of the locking groove. The earphone storage case also includes a closing elastic member and a closing slider. The closing elastic member is located in the groove and extends along a third direction. One end of the closing elastic member is connected to the groove wall, and the other end is connected to the closing slider. The closing slider is slidably disposed in the groove along the third direction. The closing slider has a closing guide surface on its surface away from the closing elastic member, and the lock cylinder can abut against the closing guide surface. The third direction is perpendicular to the first direction.

[0024] In one embodiment, the side of the cover slider forms at least a portion of the groove wall of the locking groove.

[0025] In one embodiment, the locking assembly further includes a second elastic member disposed within the receiving groove and extending along the first direction, one end of the second elastic member being connected to the groove wall of the receiving groove, and the other end being connected to the operating member and / or the lock cylinder.

[0026] Wireless earphones, including the earphone case as described above.

[0027] The earphone storage case and wireless earphones provided by this utility model have at least the following beneficial effects:

[0028] The housing has a receiving groove. One end of the operating component passes through one side wall of the housing and is located in the receiving groove, so that the receiving groove can limit the range of motion of the operating component. The lock cylinder of the locking component is connected to the end of the operating component located in the receiving groove, so that when the operating component moves relative to the housing, it can drive the lock cylinder to move relative to the housing, thereby realizing the switching of the lock cylinder between the locked position and the unlocked position. Since the operating component drives the lock cylinder from the locked position to the unlocked position, it needs to first complete one of the processes of sliding relative to the housing in a first direction and rotating about an axis extending in the first direction, and then complete the other process. That is, the unlocking process of the locking component is divided into two steps. On the one hand, it can increase the strength of the locking shell and the housing, reduce the risk of the shell opening accidentally, and has high reliability. On the other hand, when the headphone case is accidentally dropped, the probability that the operating component is simultaneously subjected to pressure in the axial direction and torque that drives the operating component to rotate is very low. Therefore, the risk of the lock cylinder moving from the locked position to the unlocked position due to the drop is greatly reduced, thereby improving the drop resistance of the headphone case.

[0049] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] This embodiment provides an earphone storage case that can be used to house individual earphone units, reducing the risk of unauthorized opening and offering high reliability and drop resistance.

[0051] The earphone storage case in this embodiment may only have the function of accommodating the earphone unit, or it may have both the function of accommodating the earphone unit and the function of charging the earphone unit. This embodiment does not limit this.

[0052] For example, such as Figures 1 to 10As shown, the earphone storage case includes a case body 1, an upper shell 2, an operating component 3, and a locking assembly 4. The case body 1 has an earphone slot 11 for accommodating an earphone unit 10, and a receiving groove 12 for accommodating the locking assembly and part of the operating component 3. It should be noted that the earphone slot 11 and the receiving groove 12 are not connected but are separately arranged. Optionally, in this embodiment, the receiving groove 12 is a semi-enclosed structure.

[0053] In at least one embodiment, such as Figure 2 As shown, the housing 1 may include an outer shell 14 and an inner liner 15 disposed within the outer shell 14. The earphone slot 11 and the receiving slot 12 are both disposed within the inner liner 15. The housing 1 can have various shapes; in this embodiment, the housing 1 is rectangular. In other embodiments, the housing 1 may also be ellipsoidal, cubic, etc., and this embodiment does not limit this.

[0054] In some alternative embodiments, the inner liner 15 has a protruding structure (not shown) that protrudes toward the upper shell 2, and the upper shell 2 is provided with a groove structure (not shown) that mates with the protruding structure. When the upper shell 2 is fastened to the box body 1, the protruding structure is located in the groove structure. In this embodiment, at least a portion of the receiving groove 12 is located in the protruding structure.

[0055] like Figure 4 As shown, the upper shell 2 has a first sidewall 21 and a second sidewall 22 disposed opposite to each other. The first sidewall 21 and the second sidewall 22 can be two sidewalls in the thickness direction of the upper shell 2, or two sidewalls in the length direction of the upper shell 2; this embodiment does not limit this. The first sidewall 21 is rotatably connected to the box body 1. When the box body 1 includes an outer shell 14 and an inner liner 15, the first sidewall 21 is rotatably connected to the outer shell 14. The second sidewall 22 is provided with a locking engagement structure 23. The locking engagement structure 23 can cooperate with the locking component 4 to lock the upper shell 2 and the box body 1.

[0056] In some alternative embodiments, such as Figure 2 As shown, the first sidewall 21 is rotatably connected to the outer shell 14 via the first pivot 7 and the opening elastic element 8. The first pivot 7 is fixedly disposed on the outer shell 14, the first sidewall 21 is sleeved on the first pivot 7, and the opening elastic element 8 is disposed between the first sidewall 21 and the outer shell 14, and always has the tendency to drive the upper shell 2 to rotate relative to the outer shell 14, so that the upper shell 2 opens, thereby exposing the earphone unit 10 or the earphone slot 11. For example, the opening elastic element 8 can be a torsion spring, and multiple elements can be provided to achieve automatic opening of the upper shell 2.

[0057] like Figure 2 or Figure 3As shown, the operating member 3 is slidably connected to the housing 1 along the first direction X. For example, the operating member 3 passes through the second side wall 22. One end of the operating member 3 is located inside the receiving groove 12, and the other end of the operating member 3 is located outside the housing 1 to facilitate manual operation by the user. The operating member 3 is rotatably connected to the housing 1 about an axis extending along the first direction X.

[0058] The operating component 3 provided in this embodiment can both slide relative to the box body 1 and rotate relative to the box body 1. In one embodiment, such as Figure 2 As shown, the operating component 3 can be a cylindrical shape. For example... Figure 2 or Figure 6 As shown, a through hole 13 is provided on one side wall of the box body 1. The operating member 3 can slide through the through hole 13 and can rotate around its own axis in the through hole 13.

[0059] like Figure 2 As shown, the locking component 4 in this embodiment includes a lock cylinder 41. The lock cylinder 41 is connected to one end of the operating member 3 located in the receiving groove 12, so that when the operating member 3 moves relative to the box 1, it can drive the lock cylinder 41 to move relative to the box 1. In this embodiment, the connection between the lock cylinder 41 and the operating member 3 is a fixed connection. At this time, when the operating member 3 translates, the lock cylinder 41 translates with the operating member 3; when the operating member 3 rotates, the lock cylinder 41 rotates with the operating member 3. The lock cylinder 41 has a locked position connected to the locking engagement structure 23 and an unlocked position separated from the locking engagement structure 23. When the lock cylinder 41 is in the locked position, it cooperates with the locking engagement structure 23. For example, the lock cylinder 41 is connected to the locking engagement structure 23 to lock the relative position of the box 1 and the upper shell 2, so as to lock the upper shell 2 onto the box 1. When the lock cylinder 41 is in the unlocked position, there is no connection between the lock cylinder 41 and the locking engagement structure 23. The lock cylinder 41 is separated from the locking engagement structure 23, so that the upper shell 2 can rotate relative to the box 1 and thus open.

[0060] The operating element 3 slides and rotates relative to the housing 1 to move the lock cylinder 41 from the locked position to the unlocked position. That is, sliding the operating element 3 alone cannot move the lock cylinder 41 from the locked position to the unlocked position, nor can rotating the operating element 3 alone move the lock cylinder 41 from the locked position to the unlocked position. Only when the movement of the operating element 3 includes both sliding and rotation can it move the lock cylinder 41 from the locked position to the unlocked position. For example, as... Figure 2 As shown, the lock cylinder 41 is a column, and the end face of the lock cylinder 41 facing the locking and mating structure 23 is a hemispherical surface.

[0061] In one embodiment, when unlocking is required, the lock cylinder 41 can have two strokes. First, when the operating member 3 slides relative to the housing 1 in the first direction X, it drives the lock cylinder 41 to slide relative to the upper shell 2 in the same direction X; this is the first stroke. After the first stroke, the lock cylinder 41 does not separate from the locking engagement structure 23 of the upper shell 2; the upper shell 2 remains connected to the housing 1. Next, the operating member 3 is controlled to rotate relative to the housing 1 about an axis extending along the first direction X. At this point, the operating member 3 drives the lock cylinder 41 to rotate relative to the locking engagement structure 23 until it separates from the locking engagement structure 23. At this point, the lock cylinder 41 no longer interferes with the movement of the upper shell 2, allowing the upper shell 2 to rotate relative to the housing 1, thereby unlocking the housing.

[0062] The earphone storage case provided in this embodiment has a receiving groove 12 in the case body 1. One end of the operating member 3 passes through one side wall of the case body 1 and is located in the receiving groove 12, so that the receiving groove 12 can limit the movement range of the operating member 3. The lock cylinder 41 of the locking component 4 is connected to the end of the operating member 3 located in the receiving groove 12, so that when the operating member 3 moves relative to the case body 1, it can drive the lock cylinder 41 to move relative to the case body 1, thereby realizing the switching of the lock cylinder 41 between the locked position and the unlocked position. Since when the operating member 3 drives the lock cylinder 41 from the locked position to the unlocked position, it is necessary to first realize the movement of the lock cylinder 41 relative to the case body 1 along the first... The process of sliding in one direction X and rotating around an axis extending along the first direction X is followed by another process. That is, the unlocking process of the locking component 4 is divided into two steps. On the one hand, it can increase the strength of the locking upper shell 2 and the box body 1, reduce the risk of the upper shell 2 being accidentally opened, and has high reliability. On the other hand, when the headphone storage box is accidentally dropped, the probability that the operating component 3 is simultaneously subjected to pressure in the axial direction and the torque that drives the operating component 3 to rotate is very low. Therefore, the risk that the lock cylinder 41 will move from the locked position to the unlocked position due to the drop will be greatly reduced, thereby improving the drop resistance of the headphone storage box.

[0063] In at least one possible implementation, such as Figure 5 As shown, the inner wall of the upper shell 2 is provided with a protruding block 25, and the locking and fitting structure 23 is provided on the block 25.

[0064] Optionally, such as Figure 3 As shown, the operating component 3 includes an operating rod 31, a connecting rod 32, and a stop 33 connected sequentially along the first direction X. The operating rod 31 passes through the through hole 13, and a boss is provided at one end of the operating rod 31 located in the receiving groove 12. The diameter of the boss is larger than the diameter of the through hole 13, so that the operating rod 31 will not detach from the housing 1. The middle part of the lock cylinder 41 is fixedly inserted through the connecting rod 32, and the lock cylinder 41 is sandwiched between the boss and the stop 33 to improve the connection strength between the operating component 3 and the lock cylinder 41.

[0065] The locking mechanism 23 can have various specific structures, as long as it can lock the lock cylinder 41 in different directions. In at least one possible implementation, such as Figure 4 As shown, the locking mechanism 23 includes a locking groove 231. The lock cylinder 41, in the locked position, is located within the locking groove 231; that is, the lock cylinder 41 is in the locked position when it is within the locking groove 231, and in the unlocked position when it is outside the locking groove 231. The lock cylinder 41 abuts against the groove wall of the locking groove 231, thus limiting its movement and preventing the locking mechanism 23 from moving relative to the lock cylinder 41, thereby preventing the upper shell 2 from detaching from the housing 1. In the unlocked position, the lock cylinder 41 is outside the locking groove 231. At this time, the lock cylinder 41 no longer abuts against the groove wall of the locking groove 231, and the upper shell 2 opens under the action of the opening elastic element 8.

[0066] When the operating member 3 slides in the first direction X, it can drive the lock cylinder 41 to slide in the locking groove 231 along the first direction X. At this time, the locking groove 231 restricts the lock cylinder 41 in the direction perpendicular to the first direction X, so that the lock cylinder 41 can only move along the first direction X and cannot rotate temporarily. After the lock cylinder 41 has moved a certain distance along the first direction X, when the operating member 3 rotates around the axis extending along the first direction X, it can drive one end of the lock cylinder 41 to rotate outside the locking groove 231. That is, the locking groove 231 no longer restricts the rotation of the lock cylinder 41, so that one end of the lock cylinder 41 no longer interferes with the groove wall of the locking groove 231 in the opening direction of the upper shell 2, so that the upper shell 2 can be opened smoothly.

[0067] By setting the locking groove 231, the specific structure of the locking mating structure 23 is simple, easy to process and manufacture, and has a low cost.

[0068] In one implementation, please continue to see Figure 4 The locking groove 231 includes a first sliding groove 2311 and a notch 2312 that are interconnected. One end of the lock cylinder 41 can be located in the first sliding groove 2311. When one end of the lock cylinder 41 is located in the first sliding groove 2311, that end of the lock cylinder 41 is slidably disposed in the first sliding groove 2311 along the first direction X. With this configuration, the lock cylinder 41 can only move along the first direction X under the limitation of the first sliding groove 2311. It is understood that the lock cylinder 41 can also slide out of and into the first sliding groove 2311. In this embodiment, the lock cylinder 41 can slide from the first sliding groove 2311 into the notch 2312.

[0069] Please continue reading Figure 3The groove wall of the receiving groove 12 is provided with a second sliding groove 121. The end of the lock cylinder 41 facing away from the first sliding groove 2311 can be slidably disposed in the second sliding groove 121 along the second direction Z. With this arrangement, the end of the lock cylinder 41 facing away from the first sliding groove 2311 can be located in the second sliding groove 121. In this embodiment, for ease of understanding, the end of the lock cylinder 41 near the first sliding groove 2311 is referred to as the first end 411, and the end of the lock cylinder 41 near the second sliding groove 121 is referred to as the second end 412. The first end 411 and the second end 412 are arranged opposite to each other. When the second end 412 is located in the second sliding groove 121, it can be slidably disposed in the second sliding groove 121 along the second direction Z, so that the second sliding groove 121 can limit it, thereby allowing the first end 411 to smoothly slide out of the notch 2312. The second direction Z is perpendicular to the first direction X. In some optional embodiments, the second direction Z is the height direction of the box body 1, and the first direction X is the thickness direction of the box body 1.

[0070] During operation, when the operating member 3 slides along the first direction X toward the center of the housing 1, it causes the first end 411 of the lock cylinder 41 to slide along the first direction X in the first slide groove 2311 until the first end 411 of the lock cylinder 41 is located in the notch groove 2312. At this time, the second end 412 of the lock cylinder 41 is located in the second slide groove 121. Due to the obstruction of the second slide groove 121, the lock cylinder 41 cannot continue to move along the first direction X. Then, the operating member 3 is rotated, and the first end 411 of the lock cylinder 41 moves out of the notch groove 2312, while the second end 412 of the lock cylinder 41 slides in the second slide groove 121 until the first end 411 slides out of the notch groove 2312. That is, when the operating member 3 rotates around the axis extending along the first direction X, it can cause one end of the lock cylinder 41 to separate from the notch groove 2312, and at the same time cause the other end of the lock cylinder 41 to be located in the second slide groove 121 and slide in the second slide groove 121.

[0071] In at least one embodiment, such as Figure 3 or Figure 6 As shown, the locking assembly 4 also includes a first elastic element 42. The first elastic element 42 is disposed in the second slide groove 121 and extends along the second direction Z. The other end of the lock cylinder 41 slides in the second slide groove 121, compressing the first elastic element 42. With this configuration, when the operating member 3 is rotated, causing the operating member 3 to drive the second end 412 of the lock cylinder 41 to slide in the second slide groove 121, the second end 412 compresses the first elastic element 42, allowing the first elastic element 42 to store elastic potential energy. When the external force applied to the operating member 3 disappears, the elastic force of the first elastic element 42 can push the second end 412 of the lock cylinder 41 to move in the opposite direction. For example, the operating member 3 and the lock cylinder 41 can rotate under the action of the first elastic element 42, and in the opposite direction to the rotation driven by the external force.

[0072] Optionally, the first elastic element 42 may include, but is not limited to, a spring.

[0073] In one possible implementation, the locking assembly 4 further includes a top block 43, which contacts one end of the first elastic member 42. Specifically, the top block 43 is disposed between the first elastic member 42 and the second end 412 of the lock cylinder 41. The end of the lock cylinder 41 facing away from the locking groove 231 can contact the top block 43. By providing the top block 43, the top block 43 can effectively support the second end 412 of the lock cylinder 41, reducing the risk that the end of the lock cylinder 41 will be inserted into the first elastic member 42 and unable to compress the first elastic member 42, thus achieving higher reliability.

[0074] It is understandable that the second end 412 of the lock cylinder 41 can also directly contact the first elastic element 42 without setting the top block 43.

[0075] In some optional embodiments, the groove wall of the receiving groove 12 may also be provided with a third sliding groove 122. The length direction of the third sliding groove 122 is the first direction X. The end of the lock cylinder 41 facing away from the locking groove 231 can be slidably disposed in the third sliding groove 122 along the first direction X. The third sliding groove 122 is connected to one end of the second sliding groove 121. That is, the second end 412 of the lock cylinder 41 can be located in the third sliding groove 122 and can slide in the third sliding groove 122 along the first direction X. While the first end 411 of the lock cylinder 41 slides in the first sliding groove 2311, the second end 412 slides in the third sliding groove 122, which further reduces the possibility of the lock cylinder 41 rotating in this process and improves the reliability of the locking housing 1 and the upper shell 2.

[0076] It should be noted that, in order to limit the state of the lock cylinder 41, the end of the lock cylinder 41 facing away from the locking groove 231 is located in either the third slide groove 122 or the second slide groove 121. With this configuration, the second end 412 of the lock cylinder 41 is either located in the second slide groove 121 or the third slide groove 122, thus limiting the second end 412. In turn, the lock cylinder 41 limits the operation member 3, so that when the second end 412 of the lock cylinder 41 is located in the third slide groove 122, the operation member 3 can only slide in the first direction X, and when the second end 412 of the lock cylinder 41 is located in the second slide groove 121, the operation member 3 can only rotate. This allows the operation member 3 to open the cover according to a predetermined sequence, improving the convenience of opening the cover.

[0077] In one embodiment, the end face of the top block 43 facing away from the first elastic member 42 is flush with or lower than the groove wall of the second slide groove 121. This arrangement allows the end of the lock cylinder 41 to slide smoothly from the third slide groove 122 to contact the end face of the top block 43 facing away from the first elastic member 42 without making a sound or getting stuck, thus improving the smoothness of the movement of the lock cylinder 41.

[0078] In at least one possible implementation, the locking assembly 4 further includes a second elastic member 44, which is disposed in the receiving groove 12 and extends along the first direction X. One end of the second elastic member 44 is connected to the groove wall of the receiving groove 12, and the other end is connected to the operating member 3 and / or the lock cylinder 41.

[0079] By setting the second elastic element 44, when the lock cylinder 41 moves from the locked position to the unlocked position under the action of the operating element 3, the operating element 3 moves towards the center of the housing 1 and squeezes the second elastic element 44, causing the second elastic element 44 to undergo elastic deformation. When the external force applied to the operating element 3 disappears, under the action of the second elastic element 44, the lock cylinder 41 and the operating element 3 can be pushed to move away from the center of the housing 1 in the first direction X until they are reset. This allows the lock cylinder 41 to be located below the end of the first slide groove 2311 away from the center of the housing 1 when the operating element 3 is not pressed, so that the upper shell 2 can be smoothly locked by the lock cylinder 41 during the closing process, improving the locking efficiency.

[0080] Optionally, the second elastic element 44 includes, but is not limited to, a spring. It should be noted that the second elastic element 44 is connected to the operating element 3, so that the second elastic element 44 will not separate from the operating element 3 when the operating element 3 rotates relative to the housing 1.

[0081] The second elastic element 44 is connected to the operating element 3 or the lock cylinder 41 so that the operating element 3 can be driven to move away from the center of the housing 1 in the first direction X, thereby allowing the lock cylinder 41 located at one end of the third slide groove 122 near the second slide groove 121 to move to the other end of the third slide groove 122 under the push of the second elastic element 44 until it is reset.

[0082] For example, the second elastic element 44 includes, but is not limited to, a spring.

[0083] In at least one implementation, such as Figure 4 , Figure 5 or Figure 7 As shown, the upper shell 2 has a groove 24 located on one side of the locking groove 231. In this embodiment, the groove 24 is located on one side of the locking groove 231 in the height direction of the upper shell 2. Furthermore, the earphone storage case also includes a closing elastic member 5 and a closing slider 6. The closing elastic member 5 is located in the groove 24 and extends along the third direction Y. In this embodiment, one end of the closing elastic member 5 is connected to the groove wall of the groove 24, and the other end is connected to the closing slider 6. The closing slider 6 is slidably disposed in the groove 24 along the third direction Y. The surface of the closing slider 6 facing away from the closing elastic member 5 has a closing guide surface 61. The lock cylinder 41 can abut against the closing guide surface 61, so that it can be inserted into the first sliding groove 2311 through the guidance of the closing guide surface 61, thereby locking the upper shell 2. For example, the closing elastic member 5 includes, but is not limited to, a spring.

[0084] By incorporating the closing elastic element 5, when the lock cylinder 41 presses against the closing slider 6, the closing elastic element 5 undergoes elastic deformation, thereby allowing the first end 411 of the lock cylinder 41 to smoothly insert into the first sliding groove 2311. By providing the closing slider 6, which has a closing guide surface 61, the lock cylinder 41 can smoothly insert into the first sliding groove 2311 when the upper shell 2 moves close to the box body 1 to close, reducing the risk of jamming.

[0085] In one embodiment, such as Figure 4 As shown, at least part of the groove wall of the locking groove 231 is formed on the side of the lid sliding block 6. With this configuration, when the lid sliding block 6 slides relative to the upper shell 2, a notch is formed in the groove wall of the first groove 2311. The first end 411 of the lock cylinder 41 can smoothly enter the first groove 2311 through this notch, which further improves the smoothness of the lock cylinder 41 entering the first groove 2311, thereby improving the smoothness of the upper shell 2 and the box body 1 locking and improving the ease of operation.

[0086] In one embodiment, a button (not shown in the figure) may be provided on the end of the operating lever 31 away from the receiving groove 12 to increase the operating area of ​​the operating lever and make it more convenient for the user to operate. The specific size of the button can be set according to the actual situation.

[0087] It should be noted that when the external force applied to the operating member 3 disappears, both the lock cylinder 41 and the operating member 3 reset under the action of the first elastic member 42 and the second elastic member 44. At this time, the first end 411 of the lock cylinder 41 is opposite to the closing guide surface 61 of the closing slider 6 in the third direction Y. During the closing process, the closing guide surface 61 will contact the first end 411 of the lock cylinder 41 and guide the first end 411.

[0088] The earphone storage case provided in this embodiment is used as follows:

[0089] When the cover needs to be opened, first press the operating component 3 to push the first end 411 of the lock cylinder 41 to slide in the first slide groove 2311, and the second end 412 to slide in the third slide groove 122, until one end of the lock cylinder 41 is located in the notch groove 2312 and the other end of the lock cylinder 41 is located at the top of the second slide groove 121, thus achieving pre-unlocking. Then control the operating component 3 to rotate (that is, rotate relative to the housing 1 about the axis along the first direction X). At this time, the first end 411 of the lock cylinder 41 warps and disengages from the notch groove 2312. The upper shell 2 will automatically open under the elastic force of the opening elastic component 8.

[0090] When the cover needs to be closed: Manually close the upper shell 2. The cover-closing slider 6, mounted on the upper shell 2, moves closer to the first end 411 of the lock cylinder 41 along with the upper shell 2. When the cover-closing slider 6 contacts the first end 411 of the lock cylinder 41, continue to press down on the upper shell 2. The lock cylinder 41 pushes the cover-closing slider 6 to slide in the groove 24 and compresses the cover-closing elastic element 5 until the first end 411 of the lock cylinder 41 is inserted into the first slide groove 2311 under the guidance of the cover-closing guide surface 61, thus closing the cover. At this time, the cover-closing slider 6 is reset under the drive of the cover-closing elastic element 5 to block the first end 411 of the lock cylinder 41 and prevent the first end 411 of the lock cylinder 41 from sliding out of the first slide groove 2311 from the cover-closing slider 6.

[0091] This embodiment also provides a wireless earphone, including the earphone storage case described above, which has high drop resistance.

[0092] For example, the wireless earphones also include an earphone unit 10, which is detachably placed in the earphone slot 11 for storage in the earphone storage case.
