The housing 200 is a base member of the charging cartridge, and the housing 200 may provide a mounting base for other components of the charging cartridge. In the embodiment of the present invention, the housing 200 has an accommodating space communicating with the outside through the opening 210.

The wireless earphone 100 can be accommodated in the moving part 300, the moving part 300 is provided with a charging module capable of charging the wireless earphone 100, the moving part 300 is provided with a second limiting part 310, the moving part 300 is connected with the housing 200, and the moving part 300 can move between an extending position and a retracting position through the opening 210, in the retracting position, the moving part 300 is positioned in the housing 200, and in the moving direction of the moving part 300, the first limiting part 220 is in limiting fit with the second limiting part 310; in the extended position, the moving portion 300 is at least partially disposed outside the housing 200, and the first position-limiting portion 220 is separated from the second position-limiting portion 310.

Specifically, in a case where the wireless headset 100 is received in the moving part 300 and the moving part 300 is located at the retracted position, the wireless headset 100 is electrically connected to the charging module on the moving part 300, thereby achieving an effect of charging the wireless headset 100. It should be noted that the charging module may include a battery and an electrical connection portion electrically connected to the wireless headset 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 position-limiting portion 220 and the second position-limiting portion 310 can be in a plurality of position-limiting matching manners, for example, the first position-limiting portion 220 and the second position-limiting portion 310 are magnetically limited, optionally, the first position-limiting portion 220 can include a first hook 221, the second position-limiting portion 310 can include a second hook 311, and in the retracted position, the first hook 221 and the second hook 311 are in clamping fit to enable the first position-limiting portion 220 and the second position-limiting portion 310 to be in position-limiting fit.

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

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

In the charging cartridge disclosed in the embodiment of the present invention, the moving part 300 may move between an extended position in which the moving part 300 is at least partially located outside the housing 200 and a retracted position in which the moving part 300 is located inside the housing 200 through the opening 210 of the housing 200. In the using process, a user only needs to manually press the pressing portion 500, the pressing portion 500 can drive the first limiting portion 220 to be separated from the second limiting portion 310, then the moving portion 300 moves towards the extending position, so that the moving portion 300 is at least partially located outside the housing 200, at this time, the user can take the wireless headset 100 located in the moving portion 300, or the user puts the wireless headset 100 back to the moving portion 300, and finally the moving portion 300 moves towards the retracting position, so that the moving portion 300 is located inside the housing 200, at this time, the first limiting portion 220 is in limiting fit with the second limiting portion 310, so that the moving portion 300 can be kept inside the housing 200, and when the user does not use the wireless headset 100, the moving portion 300 moves towards the extending position, so that the wireless headset 100 is lost, and the storage reliability of the charging box for the wireless headset 100 is improved. Meanwhile, when the mobile part 300 is located inside the case 200, the charging box may charge the wireless headset 100. Under this kind of circumstances, the box that charges is pull formula structure, and removal portion 300 and casing 200 can the relative slip to make the assembly error of box that charges less, and the structural flexibility of this kind of box that charges is better, and then make the difficult problem that appears the dislocation of box that charges.

Meanwhile, the charging box with the drawing structure is different from the flip structure of the conventional design at present, so that the charging box is diversified in style, the style of the charging box is prevented from being the flip type, the homogenization degree of the charging box can be reduced, and the problems of monotonous style and homogenization of the charging box are solved finally.

As described above, the first position-limiting portion 220 may include the first hook 221, the second position-limiting portion 310 may include the second hook 311, and in the retracted position, the first hook 221 and the second hook 311 are in snap fit, so that the first position-limiting portion 220 and the second position-limiting portion 310 are in position-limiting fit, and the pressing portion 500 can drive the first position-limiting portion 220 and the second position-limiting portion 310 to separate from each other. Specifically, the pressing portion 500 may include a main body portion 510 and a protrusion portion 520 disposed on the main body portion 510, the protrusion portion 520 is retracted from the second hook 311, and the protrusion portion 520 contacts the first hook 221 when the pressing portion 500 drives the first limiting portion 220 to separate from the second limiting portion 310. In the using process, a user manually presses the main body portion 510, so that the protrusion 520 is in contact with the first hook 221 and pushes the first hook 221 to move, so that the first hook 221 is separated from the second hook 311, in this process, the protrusion 520 can avoid the second hook 311, and the second hook 311 is prevented from being pushed to move in the process that the protrusion 520 pushes the first hook 221 to move, so that the first hook 221 and the second hook 311 have the same direction of movement, so that the pressing portion 500 is prevented from being incapable of or difficult to drive the first limiting portion 220 to be separated from the second limiting portion 310, so that the user can conveniently control the matching between the first limiting portion 220 and the second limiting portion 310, and the charging box has higher controllability.

Further, the number of the protruding portions 520 may be multiple, the protruding portions 520 are disposed at intervals on the main body portion 510, and when the pressing portion 500 drives the first limiting portion 220 to be separated from the second limiting portion 310, at least a portion of the second hook 311 is located between any two neighboring protruding portions 520. The plurality of protrusions 520 push the first hook 221 to move simultaneously, so that the first hook 221 is separated from the second hook 311, and the efficiency of releasing the first limiting portion 220 from the second limiting portion 310 by the pressing portion 500 can be further improved undoubtedly, so that the controllability of the charging box by a user is improved, and the operation by the user is facilitated.

In the embodiment of the present invention, when the moving portion 300 is located in the housing 200, the first position-limiting portion 220 is in position-limiting engagement with the second position-limiting portion 310, and the position-limiting engagement between the first position-limiting portion 220 and the second position-limiting portion 310 can be manually performed by a user, for example, after the moving portion 300 moves into the housing 200, the user can manually control the first position-limiting portion 220 to be in position-limiting engagement with the second position-limiting portion 310, specifically, one of the first position-limiting portion 220 and the second position-limiting portion 310 can be a movable position-limiting member, and the other is a fixed position-limiting member, the fixed position-limiting member is fixedly disposed on the moving portion 300 or the housing 200, and after the moving portion 300 moves into the housing 200, the user manually drives the movable position-limiting member to be in. However, this method requires the user to manually control the first position-limiting part 220 to be in position-limiting engagement with the second position-limiting part 310 in addition to manually driving the moving part 300 to move towards the retracted position, which results in additional operation steps for the user, and thus the charging box is inconvenient for the user to operate.

Of course, when the moving portion 300 moves toward the retracted position, the first limiting portion 220 contacts with the second limiting portion 310 first, then the moving portion 300 continues to move toward the retracted position, the first limiting portion 220 and the second limiting portion 310 elastically deform, when the moving portion 300 moves toward the retracted position, the first limiting portion 220 and the second limiting portion 310 recover to the state before deformation, so that the first limiting portion 220 and the second limiting portion 310 automatically achieve limiting fit, and the first limiting portion 220 and the second limiting portion 310 achieve limiting fit in the process that the moving portion 300 moves toward the retracted position, thereby preventing additional operation steps of a user, and facilitating the operation of the user. However, in this way, when the first position-limiting portion 220 contacts the second position-limiting portion 310 and when the first position-limiting portion 220 and the second position-limiting portion 310 elastically deform, a user needs to apply a large force to push the moving portion 300.

In view of this, in an alternative embodiment, the first hook 221 and the second hook 311 may be provided with a guiding inclined surface, and the guiding inclined surface of the first hook 221 is in guiding fit with the guiding inclined surface of the second hook 311 in the case that the moving portion 300 moves from the extended position to the retracted position. The guiding inclined plane can play a guiding role when the first limiting part 220 and the second limiting part 310 are in self-contact limiting matching, and a user only needs to apply a small force to push the moving part 300 to continue moving towards the retracting position, so that the user can control the charging box easily and conveniently.

In an optional embodiment, mounting hole 240 can be seted up to casing 200, press splenium 500 to set up in mounting hole 240, and press the first surface of splenium 500 to can with casing 200 surface parallel and level, the first surface is for pressing the surface that deviates from removal portion 300 on the splenium 500 to the outward appearance wholeness that makes this box that charges is better, prevents to appear unevenness's problem in the appearance of the box that charges, thereby improves the aesthetic property of the box that charges, and then improves the user experience of the box that charges.

As described above, the telescopic movement of the moving part 300 with respect to the housing 200 may be manually driven by a user, which is not limited in the 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 portion 300, and the driving mechanism 400 may drive the moving portion 300 to move toward the protruding position, so that the moving portion 300 can be automatically ejected without being manually driven by a user, thereby improving the automation degree of the charging box, and further improving the user experience.

Specifically, the driving mechanism 400 may be various, such as a hydraulic telescopic rod and a linear motor, but the hydraulic telescopic rod and the linear motor have complicated structures and are relatively high in cost. Based on this, in an alternative 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 resilient member is in a compressed state and in the extended position, the resilient member is in a natural state. In this case, when the user releases the position-limiting engagement between the first position-limiting portion 220 and the second position-limiting portion 310 by pressing the pressing portion 500, the elastic member can apply an ejecting force to the moving portion 300, so that the moving portion 300 moves to the extended position. The elastic piece has the advantages of simple structure, convenience in setting and lower cost, so that the cost of the charging box can be reduced.

Further, the driving mechanism 400 may also be an elastic damping mechanism, and the moving portion 300 and the housing 200 move relatively under the thrust of the elastic damping mechanism, and further, the damping value of the elastic damping mechanism may be adjustable, so that the adjustment of the relative moving speed of the moving portion 300 and the housing 200 may be realized by adjusting the damping value of the elastic damping mechanism, and further, the charging box may meet the requirements of different users on the relative moving speed of the moving portion 300 and the housing 200.

In particular, the elastic damping mechanism may comprise an elastic member and a telescopic assembly as described hereinbefore, the elastic member being capable of driving the telescopic assembly in motion. The structure and principle of the elastic damping mechanism are known in the art, and are not described herein again for the sake of brevity. Alternatively, the elastic member may be a spring.

In an alternative embodiment, two opposite surfaces of the moving part 300 may be a second surface 340 and a third surface, respectively, at least one of the second surface 340 and the third surface may be provided with a mounting groove 320, and the mounting groove 320 extends along the moving direction of the moving part 300; the elastic member is disposed in the mounting groove 320, and prevents the elastic member from protruding from the second surface 340 or the third surface, resulting in a jamming condition of the moving portion 300 during the telescopic movement, thereby improving the stability of the moving portion 300 during the telescopic movement relative to the housing 200.

Meanwhile, the scheme can prevent the elastic member from being directly arranged on the second surface 340 or the third surface and protruding out of the second surface 340 or the third surface, so that the space after the driving mechanism 400 and the moving part 300 are overlapped can be reduced, the size of the housing 200 is smaller, and the charging box can be conveniently carried by a user.

Further, the moving part 300 may be provided with a covering part 330, the covering part 330 may cover the mounting groove 320, and a surface of the covering part 330 facing away from the mounting 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 smoother, prevent the moving part 300 from generating a groove, and when the moving part 300 moves to the extending position, the appearance integrity of the moving part 300 presented to the user is better, so that the use experience of the user is better. Of course, this scheme can also prevent the covering part 330 from protruding from the second surface 340 or the third surface, thereby reducing the extra occupied space of the covering part 330, so that the size of the housing 200 can be made smaller, and further the charging box can be conveniently carried by the user. Meanwhile, when the surface of the covering part 330 facing away from the mounting groove 320 is flush with the second surface 340 or the third surface, the gap between the opening 210 and the moving part 300 may be small, so as to prevent impurities (e.g., dust, moisture, etc.) from entering into the housing 200 due to the large gap between the opening 210 and the moving part 300, which affects the reliability and stability of the charging box.

In order to enable the driving mechanism 400 to drive the moving portion 300 to extend out quickly and stably, in an alternative embodiment, the number of the elastic members may be multiple, the second surface 340 and the third surface are both provided with mounting grooves 320, and each mounting groove 320 may be provided with at least one elastic member, that is, the two opposite sides of the moving portion 300 may be provided with elastic members. The plurality of elastic members can certainly drive the moving portion 300 to be extended relatively quickly. Meanwhile, the two opposite sides of the moving portion 300 are both provided with elastic members, so that when the elastic members drive the moving portion 300, the driving force applied to the moving portion 300 is distributed relatively evenly, and the moving portion 300 is prevented from obliquely extending due to the force applied to one side of the moving portion 300, or the moving portion 300 is blocked due to the inclination of the moving portion 300, and further the moving portion 300 cannot extend, and finally the driving mechanism 400 can stably drive the moving portion 300 to extend, so that the reliability of the charging box is improved.

In order to enable the moving part 300 to move telescopically more stably, in an alternative embodiment, one of the moving part 300 and the housing 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 guide rail are in guiding fit in the moving direction of the moving part 300. The guide cooperation of the guide rail groove and the guide rail can enable the moving portion 300 to move stably, and play a role in guiding the moving portion 300, so as to prevent the moving portion 300 from being inclined and blocked, and further enable the charging box to have high stability.

Specifically, the guide groove may be located at the housing 200 and the guide may be located at the moving part 300, but since the housing 200 is thin, the provision of the guide groove on the housing 200 may cause a decrease in strength of the housing 200, thereby causing the housing 200 to be easily deformed or damaged. Based on this, optionally, the guide rail groove 350 may be located in the moving portion 300, and the guide rail 230 may be located in the housing 200, so as to prevent the strength of the housing 200 from being reduced due to the guide rail groove formed in the thinner housing 200, thereby enabling the strength of the housing 200 to be unaffected, avoiding the housing 200 from being easily deformed or damaged, and further improving the reliability of the charging box.

Based on the charging box disclosed in the embodiment of the present invention, the embodiment of the present invention further discloses an earphone assembly, the disclosed earphone assembly includes the wireless earphone 100 and the charging box described in any of the above embodiments, wherein the wireless earphone 100 can be accommodated in the charging box, and the wireless earphone 100 can be electrically connected to the mobile part 300.
