Example one

As shown in fig. 1 to 4, the embodiment of the present application provides a rotating shaft assembly 100, which is mainly used for a charging box 200 of a wireless bluetooth headset, and of course, can also be used for other storage boxes and the like that need to be opened and closed, and the following description will take the rotating shaft assembly 100 mounted on the charging box 200 as an example. The rotary shaft assembly 100 includes: the rotating shaft 20, the fixing frame 10 and the elastic clamping piece 30.

The fixing frame 10 is rotatably sleeved on the rotating shaft 20 so that the fixing frame 10 and the rotating shaft 20 rotate relatively, a plurality of clamping grooves 11 are formed in one side of the fixing frame 10 along the circumferential direction of the rotating shaft 20, and the number of the clamping grooves 11 can be two, three, four, five or the like.

The elastic clamping piece 30 is sleeved on the rotating shaft 20 and is not opposite to the rotating shaft 20, and a clamping portion 332 is arranged on one side, opposite to the clamping groove 11, of the elastic clamping piece 30.

Referring to fig. 5 and 6 together, in the using process, when the rotating shaft 20 rotates by a preset angle, the clamping portion 332 can slide out from one clamping slot 11 and be clamped into another adjacent clamping slot 11, so as to achieve the positioning of the rotating shaft 20, that is, the clamping portion 332 can be clamped and positioned with the clamping slot 11 every time the rotating shaft 20 rotates by a preset angle clockwise or counterclockwise, so as to achieve the rotational positioning of the rotating shaft 20 by different angles.

Referring to fig. 9 to 12 together, for example, the spindle assembly 100 is illustrated as being mounted on the charging case 200 of a true wireless bluetooth headset. The charging case 200 includes a case body 201, a case cover 202, and the rotation shaft assembly 100. Specifically, the box cover 202 is openably and closably disposed on the box body 201, the box body 201 is fixedly connected to the fixing frame 10, and the box cover 202 is fixedly connected to the rotating shaft 20.

When the box cover 202 needs to be opened, the box cover 202 can be rotated in the plane where the box cover 202 is located to rotate the box cover 202 in the counterclockwise direction or the clockwise direction by a preset angle, for example, in the clockwise direction, the rotating shaft 20 also rotates by the preset angle along with the box cover 202, and at this time, the clamping portion 332 can slide out from one clamping groove 11 and be clamped into another adjacent clamping groove 11. When the lid 202 continues to rotate clockwise by a predetermined angle, the shaft 20 also rotates by the predetermined angle, and the locking portion 332 is locked into the next slot 11 adjacent clockwise from the current slot 11 to achieve positioning.

It can be understood that the preset angle may be 60 degrees, 70 degrees, 90 degrees, or the like, that is, after the box cover 202 rotates by the preset angle, a space for taking out one earphone in the charging box 200 may be provided, and the preset angle may be specifically designed according to the size ratio of the earphone, the box body 201, and the box cover 202.

In the above technical solution, if the preset angle is 90 degrees, the completely closed condition of the box body 201 and the box cover 202 is 0 degree, so that when the box cover 202 rotates 90 degrees, that is, the rotating shaft 20 also rotates 90 degrees, the clamping portion 332 is clamped and positioned with the clamping groove 11, and at this time, it is ensured that one of the left and right earphones can be taken out. If the cover 202 is rotated 180 degrees clockwise or counterclockwise, the cover 202 is completely opened, and at this time, two earphones can be taken out. Due to the design, the two earphones can be conveniently taken out, and the single earphone can be conveniently taken out when the box cover 202 rotates by 90 degrees. The opening mode of the charging box 200 is diversified, and the experience of the use of the charging box 200 is improved.

It should be noted that, in the process of rotating the box cover 202, the user only needs to use a thumb to apply force to the box cover 202 with a single hand, i.e., the box cover 202 can be rotated, which is convenient for operation.

Wherein, along the circumferential direction of the rotating shaft 20, the length of the opening 61 is greater than the length of the protrusion 51.

In the present embodiment, if the rotating shaft 20 drives the first rotating member 50 to rotate clockwise until the protruding portion 51 abuts against the limiting member 40, at this time, the limiting member 40 limits the first rotating member 50 to continue to rotate along with the rotating shaft 20. Since the length of the opening 61 is greater than that of the protrusion 51 along the circumferential direction of the rotating shaft 20, the second rotating member 60 and the rotating shaft 20 can still rotate a certain angle under the action of external force until the inner wall of the opening 61 abuts against the protrusion 51, and at this time, the first rotating member 50, the second rotating member 60 and the rotating shaft 20 are all limited by the limiting member 40 to continue rotating. Thus, the rotation of the rotating shaft 20 from the 0-degree position to the 180-degree position can be realized, and the interference of the limiting piece 40 is avoided. Similarly, the rotating shaft 20 can also rotate 180 degrees counterclockwise.
