It should be understood that the specific implementation manners described in this specification are only for explaining the present invention and are not intended to limit the present invention.

[0027] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in this specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0028] It should be further understood that the term "and / or" used in this specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0029] In an embodiment of the present invention, a Bluetooth headset charging case 100 is provided, which is used to charge the Bluetooth headset 200 and accommodate the Bluetooth headset 200 when it is idle.

[0030] Such as Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, the charging case 100 of the Bluetooth headset includes an upper housing 10 and a lower housing 20, both of which are hollow cylindrical. That is, the upper housing 10 and the lower housing 20 are both cylindrical structures with one end open, and the openings of the upper housing 10 and the lower housing 20 are snapped together to enclose a cylindrical receiving cavity 1. An inner chamber 30 is disposed within the receiving cavity 1 and can move up and down within and only within the receiving cavity 1. The inner chamber 30 is also cylindrical, provided with structures such as charging elastic pieces (not shown in the figure), and an earphone slot 31 for receiving and fixing a pair of Bluetooth headsets 200 is provided along the direction parallel to the central axis.

[0031] Specifically, as Figure 5 and Figure 9 shown, annular first fixing grooves 11 and second fixing grooves 21 are respectively provided at the ends of the upper housing 10 and the lower housing 20 that are close to each other. The first fixing groove 11 and the second fixing groove 21 are engaged to form a structure similar to a mortise and tenon joint, preventing the upper housing 10 and the lower housing 20 from separating from each other, thereby clamping the upper housing 10 and the lower housing 20. Among them, the upper housing 10 can be fixed, and then the lower housing 20 is rotated so that the upper housing 10 and the lower housing 20 can rotate relative to each other at any angle without causing the upper housing 10 and the lower housing 20 to separate.

[0032] A driving rod 22 with threads is vertically provided at the bottom of the lower housing 20, and a driving groove 32 adapted to the driving rod 22 is provided at one end of the inner chamber 30 close to the lower housing 20. The driving rod 22 is inserted into the driving groove 32 by rotation. When the driving rod 22 is completely inserted into the driving groove 32, one end of the inner chamber 30 abuts against the bottom of the lower housing 20, making the spatial layout design more reasonable. When the inner chamber 30 rotates relative to the lower housing 20, due to the threaded connection between the driving rod 22 and the driving groove 32, the inner chamber 30 moves in the up and down direction, thus completing the mechanical lifting of the inner chamber 30.

[0033] Among them, the side wall of the inner bin 30 is provided with a limiting groove 33 along the direction from the upper shell 10 to the lower shell 20. In this embodiment, the number of the limiting grooves 33 is two, which are respectively arranged on both sides of a diameter of the cross-section of the inner bin 30 and are both vertically arranged up and down. A limiting strip (not shown in the figure) corresponding to the limiting groove 33 one by one is arranged inside the side wall of the upper shell 10. The limiting strip is a convex structure based on the inner wall of the upper shell 10 and is engaged in the limiting groove 33, so that the limiting strip can only move up and down along the limiting groove 33. When the lower shell 20 rotates relative to the upper shell 10, that is, when the lower shell 20 and the inner bin 30 rotate relatively, the driving rod 22 and the driving groove 32 cooperate to make the inner bin 30 rise or fall. Among them, the cooperation between the limiting groove 33 and the limiting strip plays a role in preventing the upper shell 10 and the inner bin 30 from rotating relatively, that is, the inner bin 30 can only move up and down in the upper shell 10 and cannot rotate relatively. Therefore, when the lower shell 20 rotates relative to the upper shell 10, the inner bin 30 also rotates synchronously relative to the lower shell 20, so that the inner bin 30 can realize lifting, with a simple structure, convenient operation, and convenient for users to take and place the Bluetooth headset 200.

[0034] Further, as Figure 4 shown in Figure 8 , a coaxially arranged disc 23 is provided at the bottom of the lower shell 20. The peripheral edge of the disc 23 can be in contact with the side wall of the lower shell 20 or can be arranged at intervals. A pair of charging claw heads 24 are arranged on the disc 23, and a pair of receiving grooves 34 corresponding to the charging claw heads 24 are arranged on the side of the inner bin 30 close to the lower shell 20. The side of the charging claw head 24 away from the disc 23 extends into the corresponding receiving groove 34 for electrically connecting with the corresponding Bluetooth headset 200. In this embodiment, the part of the charging claw head 24 extending into the receiving groove 34 is in a cuboid shape, and the side close to the Bluetooth headset 200 is in an arc surface adapted to the outer surface of the ear handle of the Bluetooth headset 200, which is convenient for increasing the contact area between the charging claw head 24 and the Bluetooth headset 200 and improving the firmness of the connection when the Bluetooth headset 200 is charged. It can be understood that when the inner bin 30 rotates relative to the lower shell 20, since one side of the charging claw head 24 extends into the receiving groove 34, the charging claw head 24 rotates synchronously with the inner bin 30; when the inner bin 30 rises to a predetermined height, the charging claw head 24 disengages from the receiving groove 34, and then the charging claw head 24 rotates with the rotation of the disc 23. Among them, the charging claw head 24 can move a predetermined distance along the radial direction of the disc 23 in the receiving groove 34.

[0035] Further, a threaded rack 231 is provided on one side of the disk 23 away from the bottom of the lower housing 20, and a threaded groove 241 for cooperating with the threaded rack 231 is formed on one side of the charging claw head 24 close to the disk 23. In this embodiment, the charging claw head 24 is provided with a pair of equally spaced threaded grooves 241, which cooperate with the rack segments of two adjacent circles at the same time. The center of the threaded rack 231 is provided on the central axis of the driving rod 22. When the lower housing 20 rotates, that is, when the charging claw head 24 rotates relative to the disk 23, through the cooperation of the threaded groove 241 and the threaded rack 231, it is equivalent to the charging claw head 24 moving along the threaded rack 231, so that the charging claw head 24 generates a radial displacement on the disk 23, that is, the charging claw head 24 approaches or moves away from the Bluetooth headset 200 on the inner bin 30 along the radius of the disk 23. It should be noted that when the charging claw head 24 disengages from the receiving groove 34, the charging claw head 24 has not yet disengaged from the threaded rack 231.

[0036] Further, a clamping block (not shown in the figure) is provided on one side of the charging claw head 24 close to the Bluetooth headset 200. The clamping block is used to cooperate with a clamping groove (not shown in the figure) on the Bluetooth headset 200 to fix the Bluetooth headset 200 on the inner bin 30. Specifically, when the inner bin 30 is at the position closest to the lower housing 20, there is a gap between the inner bin 30 and the bottom wall of the upper housing 10. At this time, the charging claw head 24 is pressed against and abutted against the charging part of the corresponding Bluetooth headset 200, so as to realize the charging function, and the clamping block of the charging claw head 24 extends into the clamping groove of the Bluetooth headset 200, so as to fix the Bluetooth headset 200 on the inner bin 30 and prevent the Bluetooth headset 200 from falling off the inner bin 30. When the inner bin 30 needs to rise, the charging claw head 24 moves away from the corresponding Bluetooth headset 200 along the radius of the disk 23 under the action of the disk 23, so that the clamping block disengages from the clamping groove and releases the clamping effect on the inner bin 30.

[0037] In an embodiment of the present invention, a pick-and-place hole 13 is formed on one side of the upper housing 10 away from the lower housing 20, and the pick-and-place hole 13 is provided with a movable closing assembly 14. When the inner bin 30 rises, the closing assembly 14 opens, facilitating the user to pick up and place the Bluetooth headset 200; when the inner bin 30 descends, the closing assembly 14 closes the pick-and-place hole 13, preventing the Bluetooth headset 200 from falling and playing a role in dust prevention and the like.

[0038] In one embodiment, as Figures 1 - 5As shown, the closing assembly 14 includes a plurality of vanes 141. In this embodiment, the vanes 141 are willow-leaf shaped, with the tip portions approaching each other. When all the vanes 141 are gathered together, all the vanes 141 form a complete circular surface, and the tips of the vanes 141 are located at the center of the circular surface, thereby closing the pick-and-place hole 13. Specifically, at one end of the upper housing 10 where the lower housing 20 is connected, there is a drive housing 25 extending along the inner wall of the upper housing 10. The drive housing 25 is coaxially arranged with the lower housing 20, and their inner walls are flush. The end far from the lower housing 20 is provided below the pick-and-place hole 13. It can be understood that a circular shielding structure is provided on the periphery of the pick-and-place hole 13. At the end of the drive housing 25 far from the lower housing 20, a drive ring 251 is vertically provided inward. The drive ring 251 is provided below the shielding structure on the periphery of the pick-and-place hole 13. The drive ring 251 is provided with strip-shaped drive holes 252 corresponding to the vanes 141 one by one. On the side of the vane 141 close to the drive hole 252 away from the tip, there is a connecting block 12, so that it can be movably engaged in the corresponding drive hole 252. The drive holes 252 are straight strip-shaped or arc strip-shaped. When the lower housing 20 drives the drive housing 25 to rotate, the drive holes 252 drive the vanes 141 to gather and close or disperse and open, thereby closing or opening the pick-and-place hole 13.

[0039] In another embodiment, as Figures 6 - 9 shown, the closing assembly 14 includes a movable flip cover 142 provided on the upper housing 10 and a drive assembly 143 for driving the flip cover 142 to open and close. The drive assembly 143 is connected to the lower housing 20. The flip cover 142 includes a circular cover surface 1421. The area of the cover surface 1421 is larger than the area of the pick-and-place hole 13. A connecting handle 1422 is provided at the edge of the cover surface 1421. The connecting handle 1422 is fixed to the end of the upper housing 10 far from the lower housing 20 through a rotating shaft 1423. The drive assembly 143 is connected to the end of the connecting handle 1422 far from the cover surface 1421, that is, the rotating shaft 1423 is provided between the drive assembly 143 and the cover surface 1421. The drive assembly 143 includes a threaded lead screw 1431, a nut 1432, a connecting rod 1433, and a drive gear 1434.

[0040] Specifically, the outer surface of the inner bin 30 is spaced from the inner walls of the upper housing 10 and the lower housing 20, that is, there is an annular gap between the outer surface of the inner bin 30 and the inner sides of the side walls of the lower housing 20 and the upper housing 10. A threaded lead screw 1431 is provided outside the inner bin 30, and a nut 1432 is provided on the threaded lead screw 1431. The nut 1432 can move up and down along the threaded lead screw 1431. The nut 1432 is connected to the connecting handle 1422 of the flip cover 142 through a connecting rod 1433, that is, the up and down movement of the nut 1432 drives the cover surface 1421 of the flip cover 142 to open and close through the connecting rod 1433. Among them, the connecting rod 1433 also plays a role in limiting the nut 1432 to prevent the nut 1432 from rotating synchronously with the threaded lead screw 1431. A circle of gears is provided on the side wall of the disc 23, and one end of the threaded lead screw 1431 close to the lower housing 20 is engaged with the side wall of the disc 23 through a driving gear 1434. When the disc 23 rotates, it drives the threaded lead screw 1431 to rotate, causing the nut 1432 to lift along the threaded lead screw 1431, thereby driving the closing or opening of the flip cover 142.

[0041] Therefore, by rotating the blades or automatically flipping the cover to open and close the access hole 13 of the upper housing 10, the entire mechanical lifting method is not rigid, more flexible, and more beautiful in appearance, enhancing the user experience.

[0042] The working principle of the present invention is as follows:

[0043] When it is necessary to take out the Bluetooth headset 200, the upper housing 10 and the lower housing 20 are rotated relative to each other (for example, one hand holds the upper housing 10 and the other hand rotates the lower housing 20); the disc 23 rotates synchronously to drive the charging claw head 24 to release the corresponding Bluetooth headset 200; then the inner bin 30 moves upward along the driving rod 22 under the rotational action of the driving groove 32; at the same time, the rotation of the driving shell 25 driven by the lower housing 20 causes all the blades 141 to open, or the cover surface 1421 of the flip cover 142 to turn up. When the inner bin 30 rises to the maximum height, all the blades 141 have been fully opened or the cover surface 1421 of the flip cover 142 has been turned up to the maximum angle, thus facilitating the user to take out the Bluetooth headset 200. It can be understood that when it is necessary to place the Bluetooth headset 200 for charging, the above process can be reversed, which will not be elaborated here.

[0044] In summary, for the Bluetooth headset charging case 100 provided by the present invention, the upper case 10 and the lower case 20 are rotatably and movably connected, and the inner case 30 for fixing the Bluetooth headset 200 is arranged inside the upper case 10 and the lower case 20. Due to the limiting effect of the limiting strip and the limiting groove 33, the inner case 30 can only move up and down along the upper case 10 and cannot rotate relative to the upper case 10. By rotating the lower case 20 or the upper case 10, the driving rod 22 and the driving groove 32 rotate relative to each other, thereby causing the inner case 30 to rise or fall. Therefore, the present invention adopts a mechanical lifting method, which has a simple structure, flexible lifting without being rigid, and facilitates the user to take and place. Compared with the electric lifting method, it improves the power utilization rate and reduces the requirement for the design space.

[0045] The present invention is not limited only to what is described in the specification and embodiments. Therefore, for those skilled in the art, additional advantages and modifications can be easily achieved. Thus, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrated examples shown and described herein.
