Technical Field

The application belongs to the technical field of electronic products, and particularly relates to a charging device and earphone equipment.

Background

The earphone is the more important equipment among the mobile communication, and the earphone can be divided into wired earphone and wireless earphone two main categories, because wired earphone wears and accomodates all inconveniently, this makes wireless earphone receive more and more users' liking in recent years. Wireless headsets are typically provided with a dedicated charging device, such as a headset charging box. The earphone can be charged by putting the earphone into the earphone charging box, so that the cruising ability of the earphone is enhanced.

In the related art, the charging structure adopted in the earphone charging box mainly has two forms of a pogo ping structure and a spring plate structure. Pogo ping structures are only applied to low-end products, while shrapnel structures are more applied to medium-and high-end products. The elastic sheet structure comprises a bottom elastic structure. The bottom bullet structure has the lowest cost and convenient assembly, and can be directly assembled in the earphone charging box on the circuit board by SMT (surface mount technology), thereby having better application prospect. However, referring to fig. 1, the exposed part of the bottom bullet structure for charging, i.e. one end of the electrical contact 4, is directly tilted, which results in that when a cleaning tool, such as a cotton swab, is used to clean the inside of the charging box of the earphone, the cleaning tool is easily collided or hooked with the electrical contact 4, so that the electrical contact 4 is tilted and deformed, which may be referred to as a hang-over phenomenon, which may cause damage to the bottom bullet structure, and thus may affect the service life of the charging box of the earphone.

The circuit board 2 is disposed in the inner cavity. The elastic member 3 includes a first end portion 31, a second end portion 32, and a charging portion 33 disposed between the first end portion 31 and the second end portion 32; the first end portion 31 is electrically connected to the circuit board 2, the second end portion 32 abuts against an inner wall of the housing 1, the charging portion 33 extends from the opening 11, and the charging portion 33 protrudes from a surface of the opening 11. In the case where the device to be charged is in contact with the charging portion 33 for charging, the second end portion 32 is separated from the inner wall of the housing 1.

In the embodiments of the present application, a new form of ground spring structure, i.e. the spring member 3, is provided for the charging device. The structure and the assembly mode of the elastic piece 3 are different from the prior bottom bullet structure, and the second end part 32 on the elastic piece can be in abutting relation with the inner wall of the shell 1 to protect the charging part 33 on the elastic piece 3, so that the charging part 33 can be prevented from being turned up and deformed under the action of external force.

The conventional bottom bullet structure is shown in fig. 1, and for example, the bottom bullet structure is applied in an earphone charging box, so as to explain the defects of the conventional bottom bullet structure. Usually, the electric contact part 4 (which is a part of the bottom spring structure) can be seen in the charging chamber of the earphone charging box, and the electric contact part 4 is a structure with a tilted end, so that when a user cleans the inside of the charging chamber by using a cleaning tool such as a cotton swab, the cotton swab has a great possibility of colliding with the end of the electric contact part 4. The force scene of the user when cleaning is performed is often multi-directional, which may cause the electrical contact 4 to be hooked or collided to cause the electrical contact 4 to be turned up and deformed, i.e. the electrical contact 4 is turned over. The technical scheme of the elastic piece provided by the embodiment of the application can well overcome the defects in the prior art, and the second end part 32 of the elastic piece 3 can ensure that the charging part 33 is not easy to turn up and deform under the action of external force in any direction. Thus, the charging device is convenient to clean.

In an alternative example of the present application, referring to fig. 5 and 6, the elastic member 3 includes a charging portion 33, wherein the charging portion 33 is a cylindrical structure with an arc-shaped top. This design provides a great improvement in the strength of the spring 3. Moreover, since the outer wall of the charging portion 33 is of an arc-shaped structure, when the cleaning device is used for cleaning, a cleaning tool such as a cotton swab can slide off the outer wall surface, so that the charging portion 32 is not turned up and deformed, and the anti-hanging-over performance of the charging portion 33 is improved.

The charging portion 33 is a cylindrical structure with an arc-shaped top. The structure may be formed by stamping. Of course, other forms known to those skilled in the art may also be employed.

It should be noted that, the structural forms (the V-shaped structure and the cylindrical structure) of the charging portion 33 in the two alternative examples are matched with the second end portion 32 to be in contact with the inner wall of the housing 1, so that the phenomenon that the charging portion 33 is turned up and deformed under the action of external forces in different directions can be well avoided.

In an alternative example of the present application, the first end 31 of the elastic member 3 may be soldered to the circuit board 2 in a patch manner. The assembly mode is simple and easy to realize.

In an alternative example of the present application, referring to fig. 3 to 6, a bending portion 34 is disposed between the first end portion 31 and the charging portion 33, and the bending portion 34 may be configured to bend so that the first end portion 31 and the charging portion 33 are not in the same plane.
