Detailed Description

An earphone charging device 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 5.

As shown in fig. 1 to 5, the earphone charging device according to the embodiment of the present invention includes a charging chamber 1, at least one charging cord 2, and at least one earphone 3.

Specifically, the one end of charging wire 2 is established inside charging storehouse 1, and the other end of charging wire 2 is for charging storehouse 1 pull. Earphone 3 and charging wire 2 joinable and separable, the above-mentioned other end of charging wire 2 stretches out charging chamber 1 and with earphone 3 joint in order to charge earphone 3 when earphone 3 charges, earphone 3 and the above-mentioned other end separation of charging wire 2 and the partly withdrawal of charging wire 2 are inside charging chamber 1 when earphone 3 uses.

For example, in the example of fig. 1-5, when the earphone 3 is used, the user can separate the earphone 3 from the other end of the charging cord 2 and retract a portion of the charging cord 2 inside the charging chamber 1, and another portion of the charging cord 2 is exposed outside the charging chamber 1; when earphone 3 does not have the electricity soon, the user can not pull out above-mentioned some follow charging chamber 1 of charging wire 2, directly with earphone 3 with the above-mentioned other end joint of charging wire 2 in order to charge earphone 3, perhaps, the user can also be through stretching the partial charging wire 2 that exposes outside charging chamber 1 to pull out the partial charging wire 2 that is located charging chamber 1 inside, and with earphone 3 with the above-mentioned other end joint of charging wire 2 in order to charge earphone 3. Wherein, in 3 charging process of earphone, earphone 3 can use while charging to can satisfy user's demand better, can reduce the risk that earphone 3 loses effectively simultaneously. When accomodating earphone 3, can with the above-mentioned other end of charging wire 2 and the joint of earphone 3, later with the whole retraction of charging wire 2 inside storehouse 1 that charges and earphone 3 also place in storehouse 1 that charges. From this, charge earphone 3 through charging wire 2, can need not to set up the needle of charging on the earphone 3 to can avoid the needle of charging to appear crooked and influence the charging effect of earphone 3 when the welding, can reduce earphone charging device 100's cost simultaneously. In addition, through when earphone 3 uses, inside the partly withdrawal charging bin 1 of charging wire 2, can be when earphone 3 fast does not have the electricity with the above-mentioned other end and the joint of earphone 3 of charging wire 2 fast.

According to the earphone charging device 100 of the embodiment of the utility model, the charging wire 2 capable of being pulled out is arranged in the charging bin 1, and the earphone 3 is charged through the charging wire 2, so that compared with the traditional TWS wireless earphone, a charging needle does not need to be arranged on the earphone 3, the charging effect of the earphone 3 can be effectively ensured, and the cost of the earphone charging device 100 can be reduced.

According to some embodiments of the present invention, referring to fig. 4, at least one recess 11 for receiving the earphone 3 is formed on the charging chamber 1, and the shape of the recess 11 is adapted to the shape of the earphone 3, so that the earphone 3 can be securely mounted in the recess 11, and the earphone 3 is prevented from being lost. The charging cord 2 is telescopically arranged in the concave part 11, so that the structure of the earphone charging device 100 is more compact, and the miniaturization design of the earphone charging device 100 is facilitated.

Furthermore, a through hole is formed on the concave part 11, the one end of the charging wire 2 is positioned inside the charging bin 1, and the other end of the charging wire 2 penetrates through the through hole and extends into the concave part 11. The above-mentioned other end of the charging cord 2 is provided with a fitting member 21, the fitting member 21 being engaged with the earphone 3 to charge the earphone 3 when the earphone 3 is charged, the maximum cross-sectional area of the fitting member 21 being larger than the cross-sectional area of the through hole. For example, a through hole may be formed in the bottom wall of the recess 11 and the through hole penetrates the bottom wall, the fitting member 21 may be cylindrical in shape, the through hole may be a circular hole, and the diameter of the fitting member 21 is larger than that of the through hole. Thereby, the above-mentioned other end of the charging cord 2 can be prevented from coming out of the recess 11, while the user can pull the charging cord 2 out of the recess 11 or retract it into the recess 11 by means of the tension fitting 21.

Further, a receiving groove 12 penetrating the surface of the charging chamber 1 is formed on the side wall of the recess 11, and at least a portion of the fitting member 21 and a portion of the charging cord 2 are fitted in the receiving groove 12 when the earphone 3 is separated from the charging cord 2. Referring to fig. 4, when the earphone 3 is in use, the user may pull the charging cord 2 out of the recess 11 and insert the fitting member 21 in the receiving groove 12, so that the above-mentioned other end of the charging cord 2 may be prevented from being retracted into the recess 11. When it is necessary to charge the earphone 3, the user can directly pull the fitting member 21 out of the receiving groove 12 and engage the fitting member 21 with the earphone 3 to charge the earphone 3. From this, can realize the quick charge to earphone 3, can effectively avoid charging wire 2 broken string suddenly simultaneously, promote user experience.

In some alternative embodiments, the receiving groove 12 includes a first receiving groove 121 and a second receiving groove 122 communicating with each other, the second receiving groove 122 is connected between the first receiving groove 121 and the recess 11, the cross-sectional area of the first receiving groove 121 is larger than that of the second receiving groove 122, and when the earphone 3 is separated from the charging cord 2, the at least one portion of the fitting member 21 fits in the first receiving groove 121. For example, in the example of fig. 4, the shape of the first receiving groove 121 is adapted to the shape of the fitting member 21, for example, the shape of the first receiving groove 121 may be circular, so that the fitting member 21 can be stably inserted into the first receiving groove 121 when the earphone 3 is used. The shape of the second receiving groove 122 may be rectangular, and the width of the second receiving groove 122 is substantially the same as the diameter of the charging wire 2, so that the charging wire 2 may be securely mounted in the second receiving groove 122. Wherein, by making the cross-sectional area of the first receiving groove 121 larger than that of the second receiving groove 122, the fitting member 21 can be prevented from slipping out of the second receiving groove 122, so as to ensure that the fitting member 21 is firmly fitted in the first receiving groove 121.

According to some embodiments of the present invention, as shown in fig. 5, the charging hole 31 is formed on the earphone 3, for example, the charging hole 31 may be formed on the bottom of the earphone 3, which facilitates the processing of the charging hole 31. A connection plug (not shown) is provided in the charging hole 31, and the fitting member 21 extends into the charging hole 31 and is electrically connected to the connection plug when the earphone 3 is charged. From this, earphone 3's charge mode is simple, convenient operation, can avoid the bad risk that earphone 3 exists when charging effectively simultaneously, has guaranteed earphone 3's charge efficiency.

According to some embodiments of the utility model, when the headset 3 is received in the recess 11, a portion of the headset 3 is exposed out of the recess 11. So configured, the user can conveniently take the earphone 3 out of the concave part 11.
