[0031] See also Figure 1-7 The utility model provides a technical solution: an earphone shell for a Bluetooth earphone, comprising an outer shell 1 and an upper cover 2 rotatably connected to the top of the outer shell 1.

[0032] A mounting groove 3 is provided in the middle of the bottom of the outer shell 1 , a charging interface 4 is installed inside the mounting groove 3 , a sliding box 5 is connected inside the mounting groove 3 , and the sliding box 5 is slidably connected to the mounting groove 3 .

[0033] A groove is provided on one side of the sliding box 5 close to the charging interface 4, and the charging interface 4 is located inside the groove. The charging interface 4 is slidably connected to the groove. A connecting plate 7 is fixedly connected to the side of the sliding box 5 away from the charging interface 4, and two connecting plates 7 are symmetrically arranged up and down.

[0034] A first spring 6 is fixedly connected to the outer side of the sliding box 5 . The first spring 6 is located on the side of the sliding box 5 away from the connecting plate 7 . Two first springs 6 are symmetrically arranged. The side of the first spring 6 away from the sliding box 5 is fixedly connected to the outer shell 1 .

[0035] A first spring 6 is provided, and when charging, the blocking plate 9 is pulled outward, and the blocking plate 9 drives the connecting plate 7 and the sliding box 5 to move outward, thereby increasing the distance between the blocking block 10 and the charging interface 4, so as to adapt to a larger charging cable connector, thereby improving the convenience of use.

[0036] After charging is completed, the elastic force of the first spring 6 drives the sliding box 5 to move into the interior of the installation slot 3, thereby facilitating the storage of the sliding box 5 and the blocking plate 9 into the interior of the installation slot 3 without causing the blocking plate 9 to protrude outward, thereby reducing the risk of scratches to the user.

[0037] The side of the connecting plate 7 away from the sliding box 5 is rotatably connected to a rotating shaft 8 , and a blocking plate 9 is fixedly connected to the outer side of the rotating shaft 8 .

[0038] Among them, a blocking block 10 is fixedly connected to the side of the blocking plate 9 away from the rotating shaft 8, and two blocking blocks 10 are symmetrically arranged. The two blocking blocks 10 are located between the two blocking plates 9, and a fixing block 11 is fixedly connected to the side of the blocking plate 9 away from the blocking block 10, and two fixing blocks 11 are symmetrically arranged.

[0039] A second spring 12 is fixedly connected to the side of the fixed block 11 away from the blocking plate 9, and a slide plate 13 is fixedly connected to the side of the second spring 12 away from the fixed block 11. The slide plate 13 is located inside the mounting groove 3, fits with the mounting groove 3, and is slidably connected to the mounting groove 3.

[0040] By arranging the sliding box 5, the connecting plate 7, the rotating shaft 8, the blocking plate 9, the blocking block 10, the second spring 12 and the sliding plate 13, when charging, the user pushes the two blocking blocks 10 upward and downward by hand, the blocking block 10 drives the blocking plate 9 to flip, the blocking plate 9 squeezes the second spring 12, and the second spring 12 contracts under the force.

[0041] Then insert the charging cable connector into the charging interface 4 to connect the charging cable, and then release the blocking block 10. At this time, the elastic force of the second spring 12 drives the fixed block 11 and the blocking plate 9 to flip and reset, and the blocking plate 9 drives the blocking block 10 to move to the middle, so that the two blocking blocks 10 cooperate to limit the connector of the charging cable.

[0042] When the charging cable is impacted or pulled, the blocking block 10 will be pushed horizontally by the charging cable connector. The horizontal force makes it difficult to flip the blocking block 10 open, thereby limiting the charging cable connector by the blocking block 10, reducing the stress on the charging cable and preventing it from falling off, thereby facilitating smooth charging.

[0043] An auxiliary slide groove 14 is provided inside the outer shell 1. Two auxiliary slide grooves 14 are symmetrically provided.

[0044] An auxiliary slide groove 14 and an auxiliary slider 15 are provided. When the sliding box 5 slides, the auxiliary slider 15 slides inside the auxiliary slide groove 14 to limit the position of the sliding box 5, thereby ensuring that the sliding box 5 slides smoothly, thereby allowing the slide plate 13 to slide smoothly inside the mounting groove 3, facilitating the normal use of the subsequent blocking plate 9 and the blocking block 10.

[0045] Working principle:

[0046] Before using the earphone shell of this Bluetooth headset, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 7 As shown, when charging, the user pushes the two blocking blocks 10 up and down with his hands, and the blocking blocks 10 drive the blocking plate 9 to flip over. The blocking plate 9 squeezes the second spring 12, and the second spring 12 contracts under the force, and then the charging cable connector is inserted into the charging interface 4 to achieve the connection of the charging cable.

[0047] Then release the blocking block 10. At this time, the elastic force of the second spring 12 drives the fixing block 11 and the blocking plate 9 to flip and reset. The blocking plate 9 drives the blocking block 10 to move toward the middle, so that the two blocking blocks 10 cooperate to limit the connector of the charging cable. When the charging cable is impacted or pulled, the blocking block 10 will be pushed in the horizontal direction by the connector of the charging cable, and the horizontal force makes it difficult to flip the blocking block 10 open, thereby realizing the limiting of the connector of the charging cable by the blocking block 10, reducing the stress on the charging cable that causes it to fall off, and facilitating smooth charging.

[0048] When charging, the blocking plate 9 is pulled outward, and the blocking plate 9 drives the connecting plate 7 and the sliding box 5 to move outward, thereby increasing the distance between the blocking block 10 and the charging interface 4, which is used to adapt to a larger charging cable connector and improves the convenience of use.

[0049] After charging is completed, the elastic force of the first spring 6 drives the sliding box 5 to move into the interior of the installation slot 3, thereby facilitating the storage of the sliding box 5 and the blocking plate 9 into the interior of the installation slot 3 without causing the blocking plate 9 to protrude outward, thereby reducing the risk of scratches to the user.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
