[0030] As Figures 1-2As shown, the fixed connecting piece 21 includes a limiting protrusion 213 connected with the elastic connecting piece 22, a clamping protrusion 211 for interference fastening in the fixed groove 12 connected with the limiting protrusion 213, and a strip-shaped connecting portion 212 connected with the clamping protrusion 211; the elastic connecting piece 22 includes a connecting portion 221 connected with the corresponding fixed connecting piece 21, an arc-shaped conductive portion 222 connected with the connecting portion 221, and a limiting portion 223 connected with the conductive portion 222, and the connecting portion 221 is obliquely arranged and makes the conductive portion 222 extend into the accommodating groove 11.

[0031] Based on the foregoing embodiment, in this embodiment, the electric connecting piece 20 has two, the accommodating groove 11 of the base 10 is used to fix the electronic device needing to be charged to ensure that the electronic device needing to be charged can maintain the charging state. The elastic connecting piece 22 is used to electrically connect the electronic device for charging, and the elastic connecting piece 22 extends the conductive portion 222 into the accommodating groove 11 so that the conductive portion 222 can press the charging connection of the corresponding electronic device, thereby making the electrical connection between the electric connecting piece 20 and the electronic device more stable and reliable, and the arc-shaped conductive portion 222 is beneficial to the plugging and unplugging of the electronic device. That is, the electronic device is connected or separated from the charging base in a plugging and unplugging manner, which can improve the convenience. The through hole 101 is obliquely arranged with the base 10, which means that the electric connecting piece 20 is also obliquely arranged with the base 10, which can increase the contact area of the electronic device to be charged and the electric connecting piece 20, and is compatible with the contacts of the earphone charging tail end in the market. The connecting portion of the fixed connecting piece 21 and the elastic connecting piece 22 is provided with a circular arc transition, and the circular arc transition is provided with a slot hole 220, which can make the elastic force of the electric connecting piece 20 moderate, has the effect of elastic buffering, and is more convenient for plugging and unplugging the charging earphone.

[0032] As shown in the figure, Figures 3-7 The accommodating groove 11 of the base 10 is wide in front and narrow at the back, and the left and right sides are half circles and are obliquely opposite, and the front and back sides are open; the fixed groove 12 is arranged at the left and right sides of the accommodating groove 11 and is biased to the back. In this way, the space of the accommodating groove 11 is larger, and the electric connecting piece 20 in the fixed groove 12 is also obliquely opposite, which is convenient for the electronic device to charge, and can also be compatible with more electronic devices to charge, such as different models of earphone tail 30 and different models of earphone tail plug.

[0033] In this embodiment, the base 10 can be made of insulating materials such as plastic or rubber, and has a cuboid shape. The accommodating groove 11 also has a cuboid shape and opens one side of the base 10 to facilitate the connection of the electronic device needing to be charged. The base 10 can also be in the shape of a cylinder or a polyhedron, and the shape of the accommodating groove 11 can match the electronic device needing to be charged, which is not limited here.

[0034] As an optional embodiment, the bottom of the base 10 opposite to the accommodating groove 11 is provided with at least one connecting column 14 for positioning and fixing when the charging base is connected with the circuit board. In the embodiment, the connecting column 14 is cylindrical and the end for fixing the circuit board is provided with an arc transition for facilitating disassembly and assembly.

[0035] As an optional embodiment, the fixed connecting piece 21 can be fixed in the corresponding fixed groove 12 by any one of the connecting modes of clamping, bonding and screwing. In the embodiment, the fixed connecting piece 21 is fixed in the corresponding fixed groove 12 by clamping for facilitating disassembly and assembly. Specifically, a pair of limiting grooves 13 for cooperating with the corresponding fixed connecting piece 21 are formed on the inner wall of the fixed groove 12, that is, the two sides of the fixed connecting piece 21 are clamped in the corresponding pair of limiting grooves 13; and in order to prevent the fixed connecting piece 21 from loosening, the two sides of the fixed connecting piece 21 are respectively protruded to form a clamping protrusion 211, the clamping protrusion 211 is deformed by extruding the inner wall of the limiting groove 13 to cause interference fastening, so that the fixed connecting piece 21 is not easy to fall off from the limiting groove 13.

[0036] Based on the foregoing embodiment, in the embodiment, the clamping protrusion 211 is located at the end of the fixed connecting piece 21 away from the elastic connecting piece 22, when the fixed connecting piece 21 is inserted and installed in the fixed groove 12 by clamping, the movement of the clamping protrusion 211 will not cause the deformation of most of the area in the limiting groove 13, so that the wear of the limiting groove 13 is smaller, and the service life is improved.

[0037] As an optional embodiment, the fixed connecting piece 21 is fixed in the fixed groove 12 by clamping, and the strip-shaped connecting part 212 passes through the fixed groove 12 and extends out of the limiting groove 13. When the charging base is fixed on the circuit board, the part of the strip-shaped connecting part 212 on the fixed connecting piece 21 extending out of the corresponding fixed groove 12 is inserted and clamped into the circuit board for electrical connection, the strip-shaped connecting part 212 extrudes the corresponding connecting part of the circuit board for interference fastening, so that the charging base is not easy to fall off from the circuit board. Specifically, the strip-shaped connecting part 212 can be made by stamping one side of the fixed connecting piece 21 extending through the hole part, and in the embodiment, the cross section of the strip-shaped connecting part 212 is a plane and / or an arc, which is more convenient for inserting or pulling out the charging base on the circuit board.

[0038] As an optional embodiment, the elastic connecting piece 22 is a sheet plate with several local bending, and the connecting part 221 is placed obliquely so that the elastic connecting piece 22 extends into the accommodating groove 11. Specifically, the distance between the conductive parts 222 of the two elastic connecting pieces 22 is smaller than the distance between the connecting parts 221. When the elastic connecting piece 22 is pressed to deform, it has a certain elasticity. When the electronic device enters the accommodating groove 11 and is fixed, the elastic connecting piece 22 in the accommodating groove 11 is forced to deform towards the inner wall of the accommodating groove 11 under pressure, thereby generating a counteracting elastic force, that is, the elastic force of the elastic connecting piece 22 is directed towards the charging connection of the electronic device, so that the conductive part 222 of the elastic connecting piece 22 is tightly electrically connected to the charging connection of the electronic device, achieving the effect of firm charging connection, large contact area and good contact.

[0039] Based on the foregoing embodiment, in this embodiment, the conductive part 222 is further provided with a limiting part 223 at one end away from the connecting part 221, for limiting the deformation of the elastic connecting piece 22. Specifically, when the electronic device enters the accommodating groove 11, it may cause the elastic connecting piece 22 to deform too much, and long-term use may cause irreversible deformation of the elastic connecting piece 22, resulting in reduced elasticity and affecting the service life of the charging base. Therefore, when the elastic connecting piece 22 is deformed too much under pressure, the limiting part 223 directly touches the fixed connecting piece 21 at one end away from the conductive part 222, preventing the elastic connecting piece 22 from continuing to deform and not affecting the electrical connection of the conductive part 222 with the charging connection of the electronic device. The shape of the limiting part 223 can be various, and the shape of the limiting part 223 is not limited here.

[0040] As an optional embodiment, the entire electric connecting piece 20 is integrally formed as a sheet plate, and the connecting part 221 is arc transitioned at the connecting part of the fixed connecting piece 21 and the elastic connecting piece 22. Specifically, when the elastic connecting piece 22 connected thereto deforms, the arc transitioned connecting part generates torsion due to torsional deformation, which is connected through the connecting part 221, thereby enhancing the elasticity of the entire elastic connecting piece 22.

[0041] The present application uses the electric connecting piece 20 to electrically connect with the electronic device that needs to be charged, and through the gravity of the electronic device itself or external force and the elastic force generated by the pressure deformation of the electric connecting piece 20 to reach a state of force balance, so that the electronic device is firmly contacted with the charging base and has a large contact area with the electric connecting piece 20, thereby preventing the electric connecting piece 20 from deforming and causing poor contact.
