The upper cover 1 is rotatably connected with the bottom case 2 through a rotating shaft 10 to open or cover the notch of the installation groove. That is, the upper cover 1 can be rotated around the rotating shaft 10 to the closed position to cover the notch of the installation slot, so that the wireless earphone 12 can be accommodated in the casing surrounded by the upper cover 1 and the bottom case 2 . And the upper cover 1 can be rotated around the rotating shaft 10 to open the notch. It should be noted that the opening of the notch mentioned here includes both opening the notch completely and partially opening the notch. Specifically, as shown in FIG. 1 , the top surface of the bottom case 2 is a quarter sphere, the upper cover 1 is a quarter sphere matched with it, and the rotating shaft 10 is fixed along the diameter corresponding to the sphere, such as the diameter of the rotating shaft 10 . Both ends are fixedly connected with the bottom case 2 . Specifically, the outer diameter of the upper cover 1 may be smaller than the spherical inner diameter of the top surface of the bottom case 2 , so that the upper cover 1 can be turned inside the top surface of the bottom case 2 . Preferably, the turning range of the upper cover 1 is 90 degrees.

Specifically, the bottom case 2 includes a base and an inner case 21 fixedly connected to the base. When the top surface of the bottom case 2 and the upper cover 1 are both quarter-spherical, the inner case 21 includes a horizontal semicircular panel and a vertical semicircular panel that are perpendicular to each other, and the two can be connected by an arc surface transition. The base includes a quarter-spherical top surface and a hemispherical bottom surface, and the bottom end of the hemispherical can be leveled for smooth placement. The horizontal semicircular panel is fixedly connected to the top of the hemispherical surface of the base, and a through hole can be opened on the horizontal semicircular panel to communicate with the interior of the hemispherical surface to form a mounting groove, and a space for the upper cover is left between the vertical semicircular panel and the top surface of the base 1 The gap that passes through when turning.

The first elastic member 4 is installed between the rotating member 3 and the bottom case 2 , and is elastically deformed when the rotating member 3 is opened with the upper cover 1 to generate a force for restoring the rotating member 3 . The first elastic member 4 may specifically be a spring, or may be other elastic materials or elastic structural members that can be elastically deformed to provide a restoring force. Specifically, the first elastic member 4 is in a natural state when the upper cover 1 is closed. When the upper cover 1 is opened, the first elastic member 4 is stretched or compressed. On the one hand, the first elastic member 4 needs to be overcome when the upper cover 1 is opened. The generated tension or pressure ensures the stability of the closed state of the upper cover 1 . On the other hand, the tension or pressure of the first elastic member 4 can realize the automatic closing of the upper cover 1 . For example, the first elastic member 4 is in a natural state when the upper cover 1 is closed, the two ends of the first elastic member 4 are respectively connected to the bottom case 2 and the rotating member 3, and the first elastic member 4 is opened when the rotating member 3 is opened with the upper cover 1 stretched.

And during the turning process of the upper cover 1 around the rotating shaft 10, the rotating member 3 fixedly connected with the upper cover 1 rotates around the rotating shaft 10 synchronously, so that the first elastic member 4 installed between the rotating member 3 and the bottom case 2 is elastically deformed, and also That is, when the user opens the upper cover 1, the elastic force of the first elastic member 4 needs to be overcome, and after the upper cover 1 is released by the external force, the restoring force generated by the first elastic member 4 drives the rotating member 3 to reset, and the rotating member 3 drives the upper cover 1. Synchronous reset can realize the automatic closing of the upper cover 1 . To sum up, the wireless earphone charging box provided by the present invention can realize the automatic closing of the upper cover 1 without manually closing the upper cover 1, which is convenient for the user to operate.

The operating part is used to receive the user's operation and push the elastic plate 5 to deform to release the clamping head 33 and the blocking part 51. . That is, the elastic plate 5 is arranged in cooperation with the rotating member 3, and the elastic plate 5 can be elastically deformed by force and can recover the deformation after the external force is released. One of the elastic plate 5 and the rotating part 3 has a clamping head 33 , and the other has a clamping part 51 that cooperates with the clamping head 33 . It is a protrusion used to abut against the clamp head 33 , such as a protrusion with the same shape as the clamp head 33 . Specifically, the rotating part 3 is installed in close contact with one side edge of the elastic plate 5 , and the side of the rotating part 3 that is adhered to the elastic plate 5 has a protruding clip 33 , such as a protruding mounting post 32 , and the clip 33 is fixed On the mounting post 32 to match with the blocking part 51 on the edge of the elastic plate 5, or the rotating part 3 has a protruding blocking part 51 on the side that is abutted with the elastic plate 5, such as having a protruding mounting post 32, which can be locked. The blocking portion 51 is fixed on the mounting post 32 to cooperate with the clip 33 on the edge of the elastic plate 5 .

Referring to FIGS. 3-4 , in one embodiment, the rotating member 3 and the elastic plate 5 are provided with clips 33 and protrusions, respectively, and the upper cover 1 can be controlled to lock the corresponding open position through the position setting of the two. As shown in FIG. 3 , when the upper cover 1 is rotated 90 degrees, the rotating member 3 engages with the clips 33 and the protrusions on the elastic plate 5 , thereby ensuring the stability of the opening state and opening angle of the upper cover 1 . When the user operates, the upper cover 1 is pushed to rotate around the rotating shaft 10 against the elastic force of the first elastic member 4 . Of course, the position where the clamping head 33 and the blocking portion 51 cooperate can also be set according to the opening requirements of the upper cover 1 , and is not limited to the position corresponding to the opening of the upper cover 1 by 90 degrees.

The stability of the open state of the upper cover 1 is ensured by the engagement of the elastic plate 5 and the rotating member 3 . In order to facilitate the user to release the engagement between the two, the upper cover 1 is automatically closed, and an operating member is arranged to cooperate with the elastic plate 5 . The operating component is installed in the bottom case 2 , and specifically may be a button 6 installed in the bottom case 2 in a sliding manner or a knob installed in the bottom case 2 in a rotating manner. The user of the operating component accepts the user's operation, and pushes the elastic plate 5 to deform accordingly to release the engagement between the clamping head 33 and the blocking portion 51 . That is to say, when the upper cover 1 needs to be closed, the user only needs to operate the operating member correspondingly, which can release the engagement between the clamping head 33 and the blocking portion 51 , and the rotating member 3 can be automatically reset under the action of the first elastic member 4 . , the operation is simple and convenient, and the open and closed state of the upper cover 1 is more stable.

In order to limit the sliding path of the button 6 and guide it, the side wall of the installation hole is provided with a chute, and the button 6 is fixed with a pin 7 inserted into the chute. When the button 6 slides, the pin 7 slides along the chute. At the same time, since the latch 7 is limited in the chute, the button 6 can be prevented from coming out of the bottom case 2 . And by setting the length of the chute, the maximum pressing displacement of the button 6 can be controlled. One end of the elastic plate 5 is fixedly connected with the bottom case 2, and the other end is in contact with the bottom surface of the button 6. When the user presses the button 6, the elastic plate 5 is deformed by force. The clamping head 33 and the blocking part 51 are engaged, so the elastic plate 5 is deformed in the opposite direction of the clamping direction, so that the clamping head 33 and the blocking part 51 are connected and released, and the rotating part 3 can be reset. The elastic plate 5 is also correspondingly capable of recovering deformation. The operating component adopts the button 6, which is convenient for the user to operate, and has a simple and reliable matching structure with the elastic plate 5.
