The housing 200 is the basic component of the charging box, and the housing 200 can provide a mounting basis for other components of the charging box. In the embodiment of the present invention, the housing 200 has an accommodating space, and the accommodating space communicates with the outside through the opening 210 .

The wireless earphone 100 can be accommodated in the mobile part 300, and the mobile part 300 is provided with a charging module that can charge the wireless earphone 100, the mobile part 300 is provided with a second limiting part 310, the mobile part 300 is connected with the casing 200, and moves The part 300 can move between the extended position and the retracted position through the opening 210. In the retracted position, the moving part 300 is located inside the housing 200, and in the moving direction of the moving part 300, the first limiting part 220 and the In the extended position, the moving part 300 is at least partially located outside the casing 200 , and the first limiting part 220 is separated from the second limiting part 310 .

Specifically, when the wireless earphone 100 is accommodated in the moving part 300 and the moving part 300 is in the retracted position, the wireless earphone 100 is electrically connected to the charging module on the moving part 300 , thereby realizing the effect of charging the wireless earphone 100 . It should be noted that the charging module may include a battery and an electrical connection portion electrically connected to the wireless earphone 100 . Further, the electrical connection portion may be a charging contact or a pogo pin, and the type of the electrical connection portion is not limited in the embodiment of the present invention.

The first limiting portion 220 and the second limiting portion 310 may be limited in a variety of ways. For example, the first limiting portion 220 and the second limiting portion 310 are limited by magnetic attraction. The limiting portion 220 may include a first hook 221, and the second limiting portion 310 may include a second hook 311. In the retracted position, the first hook 221 is engaged with the second hook 311, so that the first hook 221 is engaged with the second hook 311. The limiting portion 220 and the second limiting portion 310 limit and cooperate with each other, and the embodiment of the present invention does not limit the manner in which the first limiting portion 220 and the second limiting portion 310 limit and cooperate.

In the embodiment of the present invention, the moving part 300 can telescopically move relative to the casing 200 , and the moving process can be manually driven by the user, or a driving mechanism 400 can be provided on the casing 200 , which is not limited in this embodiment of the present invention.

The pressing portion 500 is disposed on the housing 200 , and the pressing portion 500 can drive the first limiting portion 220 to separate from the second limiting portion 310 . Specifically, the pressing portion 500 is movably disposed on the housing 200, so that when the user presses the pressing portion 500, the pressing portion 500 can have displacement or deformation relative to the housing, so that the pressing portion 500 can drive the first limit through displacement or deformation The portion 220 is separated from the second limiting portion 310 .

In the charging case disclosed in the embodiment of the present invention, the moving part 300 can move between the extended position and the retracted position through the opening 210 of the housing 200 . In the extended position, the moving part 300 is at least partially located outside the housing 200 , In the retracted position, the moving part 300 is located within the housing 200 . During use, the user only needs to manually press the pressing portion 500, the pressing portion 500 can drive the first limiting portion 220 to separate from the second limiting portion 310, and then the moving portion 300 moves toward the extended position, so that the moving portion 300 At least partially outside the housing 200, at this time, the user can take the wireless earphone 100 located in the moving part 300, or the user can put the wireless earphone 100 back to the moving part 300, and finally the moving part 300 moves toward the retracted position to The moving part 300 is located inside the casing 200, and the first limiting part 220 and the second limiting part 310 are in position-limiting cooperation, so that the moving part 300 can be kept inside the casing 200, preventing the user from using the wireless When the earphone 100 is in use, the moving part 300 moves toward the extended position, causing the wireless earphone 100 to be lost, thereby improving the storage reliability of the wireless earphone 100 by the charging box. Meanwhile, when the moving part 300 is located inside the casing 200 , the charging case can charge the wireless earphone 100 . In this case, the charging box is a pull-out structure, and the moving part 300 and the casing 200 can slide relatively, so that the assembly error of the charging box is small, and the structure of the charging box is more flexible, thereby making the charging box easier. It is more difficult to have misalignment problems.

At the same time, the charging box with the pull-out structure is different from the current conventionally designed clamshell structure, so that the styles of the charging box are diversified, and the styles of the charging boxes are prevented from being all clamshell types, thereby reducing the homogeneity of the charging box. Finally, the problem of monotonous style and homogeneity of the charging box is solved.

As described above, the first limiting portion 220 may include the first hook 221, and the second limiting portion 310 may include the second hook 311. In the retracted position, the first hook 221 and the second hook 311 are engaged with each other. The first limiting portion 220 and the second limiting portion 310 are engaged with each other, and the pressing portion 500 can drive the first limiting portion 220 and the second limiting portion 310 to separate. Specifically, the pressing portion 500 may include a main body portion 510 and a protruding portion 520 disposed on the main body portion 510 . The protruding portion 520 avoids the second hook 311 and drives the first limiting portion 220 and the second limiting portion on the pressing portion 500 . When the part 310 is separated, the protruding part 520 is in contact with the first hook 221 . During use, the user manually presses the main body portion 510, so that the protruding portion 520 contacts the first hook 221, and pushes the first hook 221 to move, so as to separate the first hook 221 from the second hook 311, During this process, the protruding portion 520 can avoid the second hook 311 to prevent the second hook 311 from being pushed to move when the protruding portion 520 pushes the first hook 221 to move. The two hooks 311 move in the same direction, thereby preventing the pressing portion 500 from being unable or difficult to drive the first limiting portion 220 to separate from the second limiting portion 310 , so that the user can control the first limiting portion 220 more conveniently. The cooperation with the second limiting portion 310 further increases the controllability of the charging box.

Further, the number of the protruding parts 520 may be multiple, and the protruding parts 520 are arranged on the main body part 510 at intervals. When the pressing part 500 drives the first limiting part 220 to separate from the second limiting part 310, The second hook 311 is at least partially located between any two adjacent raised portions 520 . The plurality of protrusions 520 push the first hook 221 to move at the same time, so that the first hook 221 and the second hook 311 are separated, which can undoubtedly further improve the pressing portion 500 to release the first limiting portion 220 and the second limiting portion. The efficiency of cooperation between the 310 improves the user's controllability of the charging box, thereby facilitating the user's operation.

In the embodiment of the present invention, when the moving portion 300 is located in the casing 200 , the first limiting portion 220 and the second limiting portion 310 are limitedly engaged, and the first limiting portion 220 and the second limiting portion 310 are limited The position matching can be done manually by the user. For example, after the moving part 300 is moved into the housing 200 , the user can manually control the first limiting part 220 and the second limiting part 310 to limit the matching. In the part 220 and the second limit part 310, one can be a movable limiter, and the other can be a fixed limiter. After moving into the housing 200, the user manually drives the movable limiter to cooperate with the fixed limiter. However, this method not only requires the user to manually drive the moving portion 300 to move toward the retracted position, but also requires the user to manually control the first limiting portion 220 to cooperate with the second limiting portion 310 in position, resulting in an additional increase in this method. The operation steps of the user make the charging box inconvenient for the user to operate and use.

Of course, when the moving portion 300 moves toward the retracted position, the first limiting portion 220 and the second limiting portion 310 first come into contact, and then the moving portion 300 continues to move toward the retracted position, and the first limiting portion 220 and The second limiting portion 310 is elastically deformed. When the moving portion 300 moves to the retracted position, the first limiting portion 220 and the second limiting portion 310 return to the state before the deformation, so that the first limiting portion 220 and the The two limit parts 310 automatically realize the limit cooperation, and the first limit part 220 and the second limit part 310 realize the limit cooperation during the process of the moving part 300 moving toward the retracted position, thereby preventing additional operation steps of the user. , which is convenient for users to operate. However, in this way, when the first limiting portion 220 and the second limiting portion 310 are in contact and the first limiting portion 220 and the second limiting portion 310 are elastically deformed, the user needs to exert a relatively large force to push the moving portion 300.

Based on this, in an optional embodiment, both the first hook 221 and the second hook 311 may be provided with guide slopes, and when the moving part 300 moves from the extended position to the retracted position, the first hook The guide slope of the hook 221 guides and cooperates with the guide slope of the second hook 311 . The guiding inclined surface can play a guiding role when the first limiting portion 220 and the second limiting portion 310 are in contact with the limiting engagement, and the user only needs to apply a small force to push the moving portion 300 to continue to move toward the retracted position. Therefore, the user can control the charging box more easily and conveniently.

In an optional embodiment, the housing 200 may be provided with a mounting hole 240 , the pressing portion 500 may be disposed in the mounting hole 240 , and the first surface of the pressing portion 500 may be flush with the outer surface of the housing 200 , the first surface In order to press the surface of the part 500 away from the moving part 300, the appearance of the charging box is better, and the appearance of the charging box is prevented from being uneven, so as to improve the aesthetics of the charging box and improve the users of the charging box. experience.

As described above, the telescopic movement of the moving part 300 relative to the casing 200 may be manually driven by the user, which is not limited in this embodiment of the present invention. Optionally, the charging box may further include a driving mechanism 400, the driving mechanism 400 is disposed on the moving part 300, and the driving mechanism 400 can drive the moving part 300 to move toward the extended position, so that the moving part 300 can be automatically ejected without the need for the user to manually perform Drive, thereby improving the automation degree of the charging box, thereby improving the user experience.

Specifically, the driving mechanism 400 can be of various types, such as a hydraulic telescopic rod and a linear motor, etc. However, the structure of the hydraulic telescopic rod and the linear motor is relatively complex and the cost is high. Based on this, in an optional embodiment, the driving mechanism 400 may include an elastic member, the elastic member is disposed on the moving portion 300, and one end of the elastic member is drivingly connected to the housing 200; in the retracted position, the elastic member is in compression state, in the extended position, the elastic member is in its natural state. In this case, after the user presses the pressing portion 500 to release the limit fit between the first limiting portion 220 and the second limiting portion 310, the elastic member can apply a pop-up force to the moving portion 300 to make the moving portion 300 move. The portion 300 is moved to the extended position. The elastic member has a simple structure, is convenient to set, and has a low cost, so that the cost of the charging box can be reduced.

Further, the driving mechanism 400 can also be an elastic damping mechanism, and the moving part 300 and the housing 200 move relatively under the thrust of the elastic damping mechanism. Further, the damping value of the elastic damping mechanism can be adjusted, so that the elastic damping mechanism can be adjusted by adjusting the elastic damping mechanism. The damping value of 100 can realize the adjustment of the relative moving speed of the moving part 300 and the casing 200 , so that the charging box can meet the requirements of different users for the relative moving speed of the moving part 300 and the casing 200 .

Specifically, the elastic damping mechanism may include the aforementioned elastic member and a telescopic assembly, and the elastic member can drive the telescopic assembly to move. The structure and principle of the elastic damping mechanism are known technologies, and are not repeated here for the sake of brevity of the text. Alternatively, the elastic member may be a spring.

In an optional embodiment, the two opposite sides of the moving part 300 may be the second surface 340 and the third surface, respectively, and at least one of the second surface 340 and the third surface may be provided with a mounting groove 320, And the installation groove 320 extends along the moving direction of the moving part 300; the elastic member is arranged in the installation groove 320 to prevent the elastic member from protruding from the second surface 340 or the third surface, causing the moving part 300 to be stuck during the telescopic movement. Therefore, the stability of the moving part 300 during telescopic movement relative to the casing 200 is improved.

At the same time, this solution can prevent the elastic member from being directly disposed on the second surface 340 or the third surface, causing the elastic member to protrude from the second surface 340 or the third surface, thereby reducing the overlap between the driving mechanism 400 and the moving part 300 Therefore, the size of the housing 200 is small, so that the charging case can be conveniently carried by the user.

Further, the moving part 300 may be provided with a covering part 330 , the covering part 330 may cover the installation groove 320 , and a surface of the covering part 330 facing away from the installation groove 320 may be flush with the second surface 340 or the third surface of the moving part 300 . The covering part 330 can make the appearance of the moving part 300 relatively flat, and prevent the moving part 300 from appearing grooves. When the moving part 300 moves to the extended position, the appearance of the moving part 300 to the user is better, so that the user can use it. Better experience. Of course, this solution can also prevent the cover portion 330 from protruding from the second surface 340 or the third surface, thereby reducing the additional space occupied by the cover portion 330 , thereby making the size of the housing 200 smaller, thereby making the charging case more convenient carried by the user. At the same time, when the surface of the cover part 330 facing away from the installation groove 320 is flush with the second surface 340 or the third surface, the gap between the opening 210 and the moving part 300 can be smaller, preventing the gap between the opening 210 and the moving part 300 The gap between them is large, so that impurities (such as dust and water vapor, etc.) enter into the casing 200, which affects the reliability and stability of the charging case.

In order to enable the driving mechanism 400 to drive the moving part 300 to extend quickly and stably, in an optional embodiment, the number of elastic members may be multiple, and the second surface 340 and the third surface are both provided with Each of the installation grooves 320 may be provided with at least one elastic member, that is, two opposite sides of the moving portion 300 may be provided with elastic members. Undoubtedly, the plurality of elastic members can drive the moving part 300 to extend relatively quickly. At the same time, two opposite sides of the moving part 300 are provided with elastic parts, so that when the elastic parts drive the moving part 300, the distribution of the driving force applied to the moving part 300 is relatively balanced, preventing the moving part 300 from being moved due to unilateral force. The moving part 300 is inclined to protrude, or the moving part 300 is stuck due to the inclination of the moving part 300, so that the moving part 300 cannot be extended, and finally the driving mechanism 400 can stably drive the moving part 300 to extend to improve the charging case. reliability.

In order to make the moving part 300 telescopically move more stably, in an optional embodiment, one of the moving part 300 and the casing 200 may be provided with a guide rail groove, and the other may be provided with a guide rail, and the guide rail groove and the casing 200 may be provided with a guide rail. The guide rails guide and fit in the moving direction of the moving part 300 . The guiding cooperation between the guide rail groove and the guide rail can make the moving part 300 move more stably, and play a guiding role for the moving part 300 to prevent the moving part 300 from tilting and jamming, thereby making the charging box more stable.

Specifically, the guide rail grooves may be located in the housing 200, and the guide rails may be located in the moving part 300. However, since the housing 200 is thin, opening the guide rail grooves on the housing 200 will reduce the strength of the housing 200, thereby causing the housing 200 Easily deformed or damaged. Based on this, optionally, the guide rail groove 350 can be located on the moving part 300, and the guide rail 230 can be located on the casing 200, so as to prevent the thin casing 200 from being provided with a guide groove to reduce the strength of the casing 200, so as to make the casing The strength of the 200 is not affected, which prevents the casing 200 from being easily deformed or damaged, thereby improving the reliability of the charging case.
