Description

Technical Field

[0001] The utility model relates to the technical field of Bluetooth earphones, in particular to a Bluetooth earphone charging structure. Background Art

[0002] Bluetooth headsets are wireless headsets that use Bluetooth technology. The principle of Bluetooth headsets is that the decoding chip in the mobile phone decodes music files such as MP3, generates digital signals and sends them to the Bluetooth headset via Bluetooth; the Bluetooth headset receives the digital signal and converts it into an analog signal that the human ear can understand through the digital-to-analog conversion chip inside the Bluetooth headset; the analog signal is amplified, and the signal amplification chip inside the headset is needed; the headset unit receives the amplified signal and emits sound. Bluetooth technology is not only used in computers, but also in many electronic devices such as mobile phones, digital cameras, camcorders, printers, fax machines, and home appliances. Bluetooth technology can be used to achieve wireless connectivity without dragging a tail. With the popularization of Bluetooth technology, home decoration no longer has to worry about the wiring of electrical appliances.

[0003] However, current Bluetooth headsets include earphones and a charging compartment. A charging port is set at the bottom of the charging compartment, and this charging port is usually directly exposed to the outside. The charging port exposed to the outside is very easy to get water ingress during daily use, causing internal circuit short circuit and malfunction. At the same time, external debris can easily block the charging port and affect the use of the earphones. Utility Model Content

[0022] A PCB circuit board is arranged inside the cabin seat 11, and an indicator light 110 is installed on the outer wall of the cabin seat 11. At the same time, the PCB circuit board is electrically connected to the charging board 22 through the circuit and the indicator light 110 arranged in the cabin seat 11; the No. 2 slide rail 3 is symmetrically arranged inside the cabin seat 11, and the No. 1 slide rail 21 is symmetrically arranged on the rear side of the charging port 2, and the No. 1 slide rail 21 is located on both sides of the charging port 2; there is a vertical spacing between the No. 1 slide rail 21 and the No. 2 slide rail 3; the lifting plate 5 is slidably installed between the No. 1 slide rail 21 and the No. 2 slide rail 3, and the two sides of the lifting plate 5 are embedded in In the No. 1 slide rail 21; the outline of the notch 51 is L-shaped, the transverse groove 6 is located directly below the lifting plate 5, and the roller 61 is rotatably installed inside the transverse groove 6; the bottom of the roller 61 protrudes from the transverse groove 6, and a long strip of protrusions is installed on the outer wall of the lifting plate 5, and the outer surface of the protrusion is set to an arc shape; a trapezoidal seat 7 is provided at the bottom of the No. 1 slide rail 21, and the outline of the trapezoidal seat 7 is L-shaped, and a bottom waterproof rubber pad 71 is installed on the outer wall of the trapezoidal seat 7, and the trapezoidal seat 7 is provided with a notch 72 penetrating the outer wall in a horizontal position, and the outline of the notch 72 is semicircular.

[0023] Working principle: When the utility model is in use, the charging head of the earphone is aligned with the charging port 2 and inserted into the inside.

[0024] When inserting the charging head into the charging port 2 , you need to first use the charging head to press against the long strip protrusion on the outer wall of the lifting plate 5 , and then gently lift it upwards. When there is a distance between the lifting plate 5 and the bottom of the charging port 2 , then hold the charging head and insert it into the charging port 2 .

[0025] When the charging head is inserted into the charging port 2, it first contacts the roller 61 on the top of the lifting plate 5. As the roller 61 rolls, the roller 61 effectively converts the sliding friction into rolling friction, effectively reducing the loss caused by the hesitation friction between the charging head and the lifting plate 5. After the charging head is aligned with the charging plate 22 and inserted, the upper lifting plate 5 moves upward along the first slide rail 21 and the second slide rail 3.

[0026] When charging is completed, the charging head can be directly unplugged. At the moment of unplugging the charging head, due to the elastic force factor generated by the deformation of the spring 41 when the lifting plate 5 moves upward, the spring 41 will reversely pull the lifting plate 5 to move downward along the No. 1 slide rail 21 and the No. 2 slide rail 3. When the lifting plate 5 moves to the bottom of the No. 1 slide rail 21, the notch 51 and the trapezoidal seat 7 overlap with each other, and the top waterproof rubber pad 52 and the bottom waterproof rubber pad 71 respectively installed on the notch 51 and the trapezoidal seat 7 fit together. The top waterproof rubber pad 52 and the bottom waterproof rubber pad 71 effectively prevent external water from entering, and the roller 61 will also be located in the groove 72.
