Technical Field

[0001] The present invention relates to the technical field of Bluetooth headsets, and in particular to a Bluetooth headset with replaceable batteries. Background Art

[0002] In today's wireless audio device market, Bluetooth headsets have become the preferred devices for consumers to listen to music, answer calls, and perform voice interactions daily due to their convenience and excellent audio experience. With the gradual cancellation of traditional headphone jacks on smartphones, the market demand for Bluetooth headsets has shown an explosive growth.

[0003] However, when using Bluetooth headsets, due to portability, the capacity of the batteries built into the headsets is small, and the battery life is significantly shortened, resulting in the inability to be used for a long time. After using for a period of time each time, it needs to be put into the headset case for charging before it can be used again. This forces users to stop using midway, reducing the usage experience of the headsets. Therefore, a Bluetooth headset with replaceable batteries is designed. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art and propose a Bluetooth headset with replaceable batteries.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A Bluetooth headset with replaceable batteries includes a headset case and two headsets. One side of the top of the headset case is rotatably connected with a case cover. Second headset slots are opened on both sides of the top of the headset case, and both second headset slots are adapted to the headsets. Rectangular chambers are opened at the bottoms of the two second headset slots inside the headset case, and the rectangular chambers are communicated with the adjacent second headset slots. Two L-shaped conductive metal strips are fixedly connected to the bottom of each rectangular chamber. A replacement box is slidably connected to the inner wall of each rectangular chamber. Two L-shaped sliding grooves are opened at the bottom of each replacement box, and the two L-shaped conductive metal strips on the same side are slidably connected in the adjacent L-shaped sliding grooves. Battery column chambers are opened on both sides of the top of the two replacement boxes. A battery column is arranged in each battery column chamber. Installation grooves are opened at the tops of the two battery columns. A limiting mechanism connected to the headset is arranged inside each installation groove.

[0007] As a further aspect of the present invention, the limiting mechanism includes two side plates fixedly connected to both sides of the top of the installation groove. Both bottoms of the two side plates are fixedly connected with sliding rods. Both bottoms of the two sliding rods are fixedly connected with a bottom plate. The circumferential surfaces of the two sliding rods are slidably sleeved with the same lifting piece. Both ends of the lifting piece are provided with round holes adapted to the sliding rods. Springs are sleeved on the circumferential surfaces of the two sliding rods at the bottom of the lifting piece. The middle of the top of the lifting piece is fixedly connected with two metal columns.
