In an embodiment of the present invention, a TWS headset charging structure 100 is provided, which is used to implement a charging function for a TWS headset, and simplifies the structure and design, thereby saving material cost.

As shown in fig. 1, the TWS headset charging structure 100 includes a headset 10 and a charging box 20. The charging case 20 is opened with a receiving groove 201 for receiving the earphone 10. The earphone 10 includes a left earphone 101 and a right earphone 102 which are designed to have an axisymmetric structure, so that the number of the receiving slots 201 in the charging box 20 is two, and the receiving slots are respectively used for receiving the left earphone 101 and the right earphone 102. In the present embodiment, the accommodating groove 201 has a conventional horizontal structure.

Specifically, as shown in fig. 2 and fig. 3, the earphone 10 includes an earphone shell 11, and a first probe 12 and a first main board 13 both disposed in the earphone shell 11. The number of the first probes 12 is two, and the first probes are respectively used for connecting a positive electrode and a negative electrode of an external power supply. The earphone shell 11 comprises an ear cap 111, a front shell 112 for fixing the ear cap 111, a middle shell 113 arranged at one end of the front shell 112 far away from the ear cap 111, and a rear shell 114 arranged at one end of the middle shell 113 far away from the front shell 112. Wherein, the ear cap 111 is used for matching with the ear canal of the human body; the front shell 112 is matched with the auricle of the human body, so that the wearing is convenient; the middle shell 113 provides strength for the headset; the rear housing 114 provides the appearance of the headset. The front shell 112, the middle shell 113 and the rear shell 114 together enclose a containing cavity structure, and the first probe 12 and the first main board 13 are contained in the containing cavity structure. In the present embodiment, the front shell 112 is fixed to the middle shell 113 by means of snap and/or glue (not shown in the figure); first mainboard 13 is fixed on mesochite 113, and is concrete, and first mainboard 13 is fixed on mesochite 113 through rubber coating or hot melt post hot melt, avoids first mainboard 13 to take place to remove in earphone shell 11, promotes the fixed steadiness of first mainboard 13.

In order to improve the waterproof performance of the earphone shell 11, one end of the first probe 12 is integrally formed with the earphone shell 11, and the end surface is flush with the outer surface of the earphone shell 11. First probe 12 is directly inlayed on earphone shell 11 promptly, and is connected with the external world through the terminal surface of one end only, has saved the trompil in traditional structure (except that earphone acoustics hole), is favorable to promoting waterproof performance. The other end of the first probe 12 is electrically connected to the first main board 13. Therefore, when the end surface of the first probe 12 communicating with the outside is electrically connected to an external power source, the charging function of the earphone 10 is realized.

Optionally, in one embodiment, the first probe 12 is a spring-type probe, i.e. one end is fixed and the other end can be moved up and down. The active ends of the first probes 12 are pressed against the first main board 13 to form an electrical connection. Specifically, the first probe 12 is vertically pressed on a copper exposing area (not shown) of a predetermined position of the first main board 13. Namely, the movable end of the first probe 12 is abutted against the copper exposing area of the first main board 13, and the design of the first main board 13 in the height direction is more free and convenient by utilizing the expansion amount of the spring type probe in the height direction. Simultaneously, because first probe 12 connects the one end in first mainboard 13 for the expansion end, consequently can be better eat first mainboard 13 when the equipment tolerance of direction of height, make first probe 12 also laminate more with the contact of first mainboard 13, do benefit to the electric connection performance who promotes first mainboard 13 and first probe 12.

In the embodiment of the present invention, as shown in fig. 4 and 5, the charging box 20 includes a box body 21, and a second probe 22 and a second main board 23 both disposed on the box body 21. It should be noted that the number of the second probes 22 is also two, and the two second probes 22 are respectively used for the positive electrode and the negative electrode of the output power source, and the distance between the two second probes 22 is consistent with the distance between the two first probes 12. The box 21 includes an upper housing 211 and a lower housing 212. The containing groove 201 is arranged on one side of the lower shell 212 close to the upper shell 211; the second main plate 23 is fixed in the lower case 212. The upper housing 211 and the lower housing 212 are rotatably coupled by a rotating shaft 213. When the upper housing 211 covers the lower housing 212, the receiving slots 201 are closed so that the earphones 10 are fixed in the corresponding receiving slots 201. Specifically, one end of the second probe 22 extends into the preset position of the receiving groove 201 to form a protruding structure, and the other end of the second probe 22 is electrically connected to the second main board 23. The second main board 23 is used for connection with an external power supply.

Optionally, in one embodiment, the second probe 22 is a spring-loaded probe. The end of the second probe 22 away from the first probe 12 is mounted on the second main board 23. That is, the fixed end of the second probe 22 is fixed on the second main plate 23, and the movable end thereof extends into the receiving groove 201. When the earphone 10 is accommodated in the accommodating groove 201, one end of the first probe 12 away from the first main board 13 is abutted with one end of the second probe 22 away from the second main board 23. Because the movable end of the second probe 22 is located in the receiving groove 201, the first probe 12 presses the second probe 22 to form interference abutment, so that the connection firmness between the first probe 12 and the second probe 22 is ensured, and the phenomenon of poor contact is avoided, thereby affecting the charging effect of the earphone.

As shown in fig. 1, the present invention also provides an earphone. The headset includes a left headset 101, a right headset 102, and a charging box 20. The left earpiece 101 and the right earpiece 102 are charged in the charging box 20 by the TWS earpiece charging structure 100 according to any of the embodiments described above.

In summary, in the TWS headset charging structure 100 provided by the present invention, the first probe 12 and the headset housing 11 are integrally formed, so that the end surface of one end of the first probe 12 is flush with the outer surface of the headset housing 11, and then the function of charging the headset 10 is realized by the abutment of the second probe 22 in the charging box 20 and the first probe 12. Therefore, on the premise of ensuring the waterproof effect, sealing structures such as annular gaskets in the traditional design are omitted, the structural design and the process are simplified, and the material cost is saved.

The utility model is not limited solely to that described in the specification and embodiments, and additional advantages and modifications will readily occur to those skilled in the art, so that the utility model is not limited to the specific details, representative apparatus, and illustrative examples shown and described herein, without departing from the spirit and scope of the general concept as defined by the appended claims and their equivalents.
