AI Technical Summary

Technical Problem

Existing Bluetooth headphones do not have wireless charging function. During the charging process, resistance loss occurs due to the internal resistance of the headphone battery and the charging circuit, which generates heat and reduces charging efficiency.

Method used

Design a wireless charging device for Bluetooth headphones, which drives the slider to move on the slide rod through the clamping plate, compresses the damping spring, clamps the charging chamber of the Bluetooth headphones, and connects it to the wireless charging base through the charging interface to achieve wireless charging. At the same time, the motor is used to drive the fan to cool down.

Benefits of technology

It realizes wireless charging of Bluetooth headphones that do not have wireless charging function, is suitable for charging chambers of different sizes, and improves charging efficiency and safety through effective cooling measures.

Abstract

The utility model relates to the field of wireless charging devices, and discloses a Bluetooth earphone wireless charging device which comprises a base, a charging interface is arranged in the center of the front end of the upper surface of the base, heat dissipation boxes are fixedly connected to the two sides of the front end of the upper surface of the base, and mounting rods are fixedly connected to the inner walls of the two sides of each heat dissipation box. Motors are fixedly connected to the front ends of rod bodies of the mounting rods, fans are fixedly connected to the output ends of the motors, and heat dissipation grooves are formed in the outer wall of the front end and the outer wall of the rear end of the heat dissipation box. According to the Bluetooth earphone charging device, through the arrangement of the motor, when the temperature of the Bluetooth earphone charging bin is relatively high during charging, the fan is driven by the motor to rotate, so that external air is sucked in by the fan and then blown out from one side facing the Bluetooth earphone charging bin; therefore, the heat of the Bluetooth earphone charging bin is taken away through the flowing air flow, so that the effect of cooling the Bluetooth earphone charging bin is achieved.
