[0020] The technical solutions in the embodiments of the utility model are described clearly and completely below. The embodiments of the utility model and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 5 The present invention provides the following three preferred embodiments:

[0022] Embodiment 1

[0023] A wireless charging device for a bone conduction headset comprises a wireless charging seat 1 for a bone conduction headset, a charging connector 2, a connecting assembly and an auxiliary assembly; a charging interface 3 is arranged on the wireless charging seat 1 for the bone conduction headset, a connecting seat 5 is fixedly arranged on the outer side of the charging interface 3, a jack is provided in the center of the connecting seat 5, and fixing blocks 4 are symmetrically fixedly arranged at both ends of the charging connector 2; the charging connector 2 is plugged into the charging interface 3, and the charging connector 2 is plugged into the jack of the connecting seat 5; the connecting assembly and the auxiliary assembly are arranged on the connecting seat 5; the connecting assembly comprises a slide groove 6, an empty groove 7, an arc block 8, a clamping block 9, a first spring 10, a swivel 11, a protrusion 12 and a ball 13; the auxiliary assembly comprises a fixing box 14, a limit block 15, a fixing column 16, a second spring 17 and a positioning block 18.

[0024] During use, after the charging connector 2 is tightly plugged into the charging interface 3, the rotating ring 11 is rotated so that the protrusion 11 pushes the arc block 8 to move, and then the clamping block 9 clamps the fixing block 4, so that the charging connector 2 and the charging interface 3 are stably plugged, thereby preventing the charging connector 2 from loosening when the bone conduction headset wireless charging stand 1 is in use, thereby ensuring the charging efficiency of the bone conduction headset.

[0025] Embodiment 2, based on embodiment 1:

[0026] The slide groove 6 in the connecting component is symmetrically arranged on the two side walls of the insertion hole of the connecting seat 5, and the empty groove 7 is symmetrically arranged in the connecting seat 5; an arc block 8 is movably arranged in the empty groove 7, and a clamping block 9 is fixedly arranged on the side end of the arc block 8, and the clamping block 9 passes through the slide groove 6, and a first spring 10 is symmetrically arranged on the side end of the arc block 8; the swivel 11 is rotatably arranged on the peripheral wall of the connecting seat 5, and a protrusion 12 is symmetrically fixedly arranged on the inner wall of the swivel 11, and a ball 13 is movably embedded at the end of the protrusion 12; the slide groove 6 corresponds to the setting position of the fixed block 4 and has the same setting group number, and the fixed block 4 is movably inserted in the slide groove 6; the clamping block 9 corresponds to the setting position of the fixed block 4 and has the same setting group number, and the two are clamped; the protrusion 12 corresponds to the setting position of the empty groove 7 and has the same setting group number, the protrusion 12 is movably arranged in the empty groove 7, and the ball 13 is clamped with the arc surface of the arc block 8.

[0027] During use, the charging connector 2 is tightly plugged into the charging interface 3 on the bone conduction headset wireless charging seat 1. At this time, the fixed block 4 on the charging connector 2 is plugged into the end of the slide groove 6. The rotating ring 11 is rotated at a certain angle. During the process, the ball 13 at the end of the protrusion 12 moves along the arc surface of the arc block 8, so that the protrusion 12 pushes the arc block 8 to move and compresses the first spring 10 until the clamping block 9 extends into the slide groove 6 and clamps the fixed block 4 to fix the position of the fixed block 4, thereby improving the connection stability of the charging connector 2; when disassembling, the rotating ring 11 is rotated in the opposite direction. During the process, the first spring 10 resets and pushes the clamping block 9 to separate from the fixed block 4, and the charging connector 2 can be pulled out.

[0028] Embodiment 3, based on embodiment 2:

[0029] The fixing box 14 in the auxiliary component is fixedly set on the peripheral wall of the connecting seat 5, and the limiting block 15 is movably clamped in the fixing box 14; a fixing column 16 is fixedly set on the side end of the limiting block 15, and the fixing column 16 passes through the fixing box 14, and a second spring 17 is set on the side end of the limiting block 15, and the positioning block 18 is fixedly set on the outer wall of the rotating ring 11; the fixing column 16 and the positioning block 18 are set in corresponding positions and the same number of groups, and the two are clamped.

[0030] When in use, the swivel 11 is conveniently rotated with the help of the positioning block 18. Before rotating the swivel 11, the fixing column 16 is pressed so that the limit block 15 compresses the second spring 17 until the fixing column 16 is separated from one side of the positioning block 18. The swivel 11 can be rotated. When the swivel 11 is rotated to a certain angle, the clamping block 9 clamps and fixes the position of the fixing block 4. At this time, the second spring 17 resets and pushes the fixing column 16 to move so that it clamps with the other side of the positioning block 18, which limits the positioning block 18, that is, fixes the angular position of the swivel 11, thereby fixing the position of the clamping block 9 and ensuring the connection stability of the charging connector 2.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
