DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0035] The embodiment of the present application discloses a TWS earphone charging case with an internal mobile power supply. Refer to Figures 1 to 5, The charging case of the TWS earphone with a built-in mobile power supply includes a base body 1, a cover body 2, and a mobile power supply main body 3. Specifically, the base body 1 is generally rectangular in shape, placed horizontally, and the length direction of the base body 1 is along the horizontal direction. Moreover, the bottom surface of the base body 1 is set to a rounded corner state to prevent scratching during use. A placement groove 11 is provided on the upper side surface of the base body 1 for placing the earphones. There are two placement grooves 11, and the two placement grooves 11 are symmetrically arranged. When the earphones are placed in the placement grooves 11, the heads of the two earphones will be close to each other; One side of the cover body 2 is rotatably connected to one side of the upper side surface of the base body 1. A recess is provided on the side surface of the cover body 2 close to the base body 1 so that the cover body 2 is in an overall thin-walled shape. When the side surface of the cover body 2 close to the base body 1 abuts against the base body 1, the recess of the cover body 2 will completely cover the two placement grooves 11 to prevent the earphones from falling out. And when the cover body 2 is closed, the surfaces of the cover body 2 and the base body 1 in the vertical direction are smoothly connected; A chamber for placing other components is provided inside the base body 1, and the mobile power supply main body 3 is arranged in this chamber. The mobile power supply main body 3 includes a battery 31 and a circuit board 32. The battery 31 serves as a container for storing power, and the circuit board 32 is electrically connected to the battery 31. An input terminal 321 and an output terminal 322 are electrically connected to the circuit board 32 to realize the charging and discharging of the battery 31. At the same time, a contact 323 is provided at the bottom of the placement groove 11, and the contact 323 is electrically connected to the circuit board 32. After the earphone is placed in the placement groove 11 in a predetermined posture, the electrode on the earphone will be electrically connected to the contact 323 so that the battery 31 can charge the earphone. Therefore, through the setting of the output terminal 322 on the circuit board 32, when people are in an outdoor environment and other electronic devices run out of power, the output terminal 322 of the circuit board 32 can be connected to the electronic device through a data cable to realize charging. At the same time, the earphone and the mobile power supply are combined into one. Without affecting the function of earphone storage and charging, it realizes the power supply to external devices. Therefore, when people travel, they only need to carry one earphone charging case, which has strong functionality and is convenient for users to use and carry. And the cover body 2 is connected to the base body 1 in a flip-up form, which is convenient for users to take out and place the earphones, and is beautiful and coordinated.

[0036] In order to prevent the earphone from falling out of the placement slot 11 due to the cover 2 being opened when charging the mobile power supply assembly, the following settings are made accordingly: the output end 322 and the input end 321 of the circuit board 32 are both arranged on the side of the base 1, and the side is the side perpendicular to the length direction of the base 1. Therefore, when charging the battery 31, it is only necessary to plug the external data cable into the side of the base 1. Compared with when the input end 321 of the circuit board 32 is arranged on the bottom surface of the base 1, when the battery 31 needs to be charged, the base 1 needs to be picked up as a whole and tilted. At this time, when the user holds the base 1 upside down, under the action of gravity, one side of the cover 2 is easily separated from the base 1, and the placement slot 11 will be exposed. , and a certain force is used when inserting the external data line into the input end 321 of the circuit board 32, so the earphone is easy to fall out of the placement slot 11 and be broken, so the input end 321 and the output end 322 of the circuit board 32 are arranged on the side to avoid the earphone from falling and being broken as much as possible. At the same time, a first magnet 12 is arranged on the seat body 1, and the first magnet 12 is embedded in the seat body 1, and a second magnet 21 is arranged on the cover body 2. The second magnet 21 is arranged on the side of the cover body 2 away from the rotationally connected to the seat body 1, and the second magnet 21 is used to adsorb with the first magnet 12, so that the connection between the cover body 2 and the seat body 1 is more stable, which can avoid the earphone from falling out of the placement slot 11 and causing damage as much as possible.

[0037] In order to increase the practicality of the earphone charging case, a multi-protocol control chip (not shown in the figure) is also provided on the circuit board 32.
