The charging contact 110 is made of a conductive material, and may be made of a metal material, such as stainless steel, copper alloy, or the like. Of course, in other embodiments, the charging contact 110 may also be made of an alloy material, such as rhodium-ruthenium alloy, plated on the surface of the metal material, so that the charging contact 110 has better wear resistance.

As shown in fig. 3, fig. 3 is a schematic structural diagram of the charging spring 30 according to an embodiment of the present application in one viewing angle. The charging spring plate 30 of the embodiment of the present application includes a fixing portion 300, an elastic portion 400, and a protrusion 600. The fixing portion 300 is configured to be installed in the charging box 20 and can be electrically connected to a charging component of the charging box 20. The elastic part 400 is connected to the fixing part 300 and is movable between a pressed position and a released position with respect to the fixing part 300. The protrusion 600 is disposed on the elastic part 400 and is used to contact with a charging contact of an audio device when the elastic part 400 is in a pressed position.

In the related art, the charging contacts of the audio device are all in direct contact with the charging spring. When there is filth in the contact that charges, sweat for example covers the contact that charges, can lead to charging contact and charging shell fragment contact failure, influences the effect of charging. The protruding portion 600 is arranged on the elastic portion 300, and when the elastic portion 300 is located at the pressed position, the protruding portion 600 can be in contact with the charging contact of the audio device, and therefore good contact between the charging contact and the charging elastic sheet is ensured.

The protrusion 600 may be a revolved body structure, a cambered surface structure, a hemispherical surface structure, a segment of a sphere, a circular truncated cone, or a truncated cone structure, and is configured to form a point-surface contact with the charging contact 110 of the audio device 10. Of course, the boss 600 may also be a combination of the different structures described above.

In the present embodiment, the protruding portion 600 forms a point-surface contact with the charging contact 110 of the audio device 10, and the point-surface contact significantly reduces the area between the protruding portion 600 and the charging contact 110 on the premise that the pressure applied to the protruding portion 600 by the audio device 10 is constant, so that the contact pressure between the charging contact 110 and the protruding portion 600 is significantly increased. Thus, when the charging contact 110 and/or the protrusion 600 is covered with dirt, the protrusion 600 can pierce the dirt, and the charging contact 110 and the charging spring 30 are ensured to be in direct contact.

Referring to fig. 3, the charging spring further includes an anti-separation element 500, and the anti-separation element 500 is disposed on the fixing portion 300 and used for stopping the elastic portion 300 from separating from the release position.

It is understood that, as shown in fig. 3, the direction in which the anti-slip assembly 500 stops the movement of the elastic part 300 may be along the width direction of the elastic part 300, along the thickness direction of the elastic part 300, or along the width direction and the thickness direction of the elastic part 300.

In the related art, since the charging spring 30 is in contact with the charging contact 110 of the audio device 10 when the audio device 10 is charged by using the charging box 20, the charging spring 30 needs to be exposed to the accommodating cavity 211 of the charging box 20. Thus, when the charging box 20 is cleaned, the cleaning tool may catch the charging spring 30, causing the charging spring 30 to be accidentally turned outwards or broken or shaken, thereby causing the charging box 20 to be out of order.

The shell fragment 30 that charges of this application embodiment is through setting up anticreep subassembly 500 for anticreep subassembly 500 can backstop elastic component 400 and break away from the release position, can avoid charging shell fragment 30 and take place unexpected turn up or fracture, and then play the effect of protection elastic component 400.

The charging spring 30 is made of a conductive material, and may be made of a metal material, such as stainless steel, copper alloy, and the like.

Referring to fig. 3, the anti-slip assembly 500 includes two blocking portions 510 disposed opposite to each other, and the two blocking portions 510 are disposed on two opposite sides of the elastic portion 400 respectively, so as to limit the elastic portion 400 between the two blocking portions 510. When the elastic part 400 shakes in the width direction, the two stopping parts 510 respectively limit the movement of the elastic part 400, thereby preventing the elastic part 400 from departing from the release position.

The stopping portion 510 may be a plate-shaped structure and perpendicular to the fixing portion 300, but not limited thereto.

Of course, it is understood that the trip prevention assembly 500 may be provided only at one side of the elastic part 400, and the trip prevention assembly 500 can stop the elastic part 400 when the elastic part 400 moves toward the trip prevention assembly 500 in the width direction thereof.

It is understood that the anti-falling off assembly 500 further includes a hook portion 520, the hook portion 520 is connected to the elastic portion 400 and can move along with the elastic portion 400, that is, when the elastic portion 400 moves between the pressed position and the released position under/without being pressed by the charging contact 110 of the audio device 10, the hook portion 520 can also move along with the elastic portion 400. The stopping portion 510 can stop the hook portion 520 from moving away from the fixing portion 300 to a releasing position.

In the related art, when the charging box 20 is cleaned, the cleaning tool may catch the charging spring 30, causing the charging spring 30 to be accidentally turned outward away from the fixing portion 300, resulting in the charging and the failure of the charging box 20.

In the present embodiment, the blocking portion 510 of the anti-slip-off assembly 500 is disposed on the fixing portion 300, and the hook portion 520 of the anti-slip-off assembly 500 is disposed on the elastic portion 400. The stop portion 510 and the hook portion 520 are engaged with each other, so that the elastic portion 400 is prevented from being turned out or broken due to the release position.

Of course, it is understood that the anti-slip-off assembly 500 may be provided only on the elastic part 400 and may move together with the elastic part 400. When the elastic portion 400 is about to be separated from the releasing position in a direction away from the fixing portion 300, the anti-separation assembly 500 can hook the fixing portion 300 to prevent the elastic portion 400 from moving in the direction away from the fixing portion 300, thereby playing a role of stopping.

Of course, the anti-slip-off assembly 500 may be fixed to only the fixing portion 300. When the elastic portion 400 is about to be separated from the releasing position in a direction away from the fixing portion 300, the anti-separation assembly 500 can hook the elastic portion 400 to prevent the elastic portion 400 from moving in a direction away from the fixing portion 300.

In the present embodiment, the two stopping portions 510 can be in stopping fit with the hook portion 520 to ensure a stopping effect and prevent the elastic portion 400 from being excessively ejected and deformed. In addition, the elastic portion 400 is partially disposed between the two stopping portions 510 to prevent the elastic portion 400 from shaking, thereby preventing the elastic portion 400 from deforming.

The blocking portion 510 has a blocking opening 511, so that the blocking portion 510 is substantially formed into an L-shape. Note that the L-shaped structure of the stopper portion 510 means: a virtual plane is provided, which is perpendicular to the width direction of the elastic part 400, and the shape of the orthographic projection of the blocking part 510 on the virtual plane is L-shaped. Of course, in other embodiments, the shape of the orthographic projection of the stopping portion 510 on the virtual plane may also be C-shaped, U-shaped or other shapes capable of stopping the hook portion 520, which is not listed here. The opening direction of the stopping opening 511 faces the vertical section 310 of the fixing portion 300, and at least a part of the hook portion 520 is movably disposed in the stopping opening 511. Since the opening direction of the stop opening 511 faces the fixing portion 300, at least a portion of the hook portion 520 is defined in a region enclosed by the stop opening 511 and the fixing portion 300.

It should be noted that the specific shape of the stopping portion 510 can be designed adaptively according to the moving direction of the stopping elastic portion 400.

For example, if the stopping portion 510 only stops the elastic portion 400 from moving in the width direction thereof, the shape of the orthographic projection of the stopping portion 510 on the virtual plane may be a regular shape or an irregular shape, for example, the regular shape may include a rectangle, a semicircle, etc., and the irregular shape may include an irregular polygon, such as the above-mentioned L-shape, U-shape, C-shape, etc., so long as the shape of the orthographic projection of the stopping portion 510 on the virtual plane coincides with the shape of the orthographic projection of the elastic portion 400 on the virtual plane.

If the stopping portion 510 needs to stop the elastic portion 400 to separate away from the fixing portion 300, the shape of the orthographic projection of the stopping portion 510 on the virtual plane may be the above-mentioned L shape, U shape, C shape or other shapes capable of playing a role of stopping, and it is sufficient that the stopping portion 510 and the hook portion 520 have an overlapping area along the moving direction of the elastic portion 400, so that the two can generate motion interference.

In the present embodiment, the orthogonal projection of the stopping portion 510 on the virtual plane has an L-shape, and both the width direction of the elastic portion 40 and the direction of the elastic portion 400 away from the fixing portion 300 can serve as the function of stopping the elastic portion 400.

Trip portion 520 includes first buckling piece 521, first extension piece 522 and trip section 523, and first buckling piece 521 sets up the free end at elastic part 400, and buckles to elastic part 400 towards first side 401 of fixed part 300, and first extension piece 522 is located first side 401, and the one end of first extension piece 522 is connected in first buckling piece 521, and the other end is connected with trip section 523, and trip section 523 backstops the cooperation with backstop portion 510.

Particularly, along the width direction of the elastic part 400, the two ends of the hook segment 523 are respectively provided with a protruding structure, and the distance between the two protruding structures is greater than the distance between the two stopping parts 510, so that the two protruding structures can move and interfere with the two stopping parts 510 respectively, and further the stopping effect is realized.

When the elastic part 400 moves from the releasing position to the pressed position, the hook segment 523 gradually moves away from the blocking portion 510. When the elastic part 400 moves from the pressed position to the released position, the hook segment 523 gradually approaches the blocking portion 510. When the elastic portion 400 continues to move in the direction away from the fixing portion 300, the blocking portion 510 can block the hook segment 523 to prevent the elastic portion 400 from separating from the releasing position.

It is understood that the present application does not limit the number of the stopping portions 510, for example, when the stopping portion 510 is one, the stopping portion 510 may be disposed on the fixing portion 300 and located at one side of the elastic portion 400. When the elastic portion 400 and the hook portion 520 are separated from the releasing position in a direction away from the fixing portion 300, the stopping portion 510 can be in stopping fit with the hook section 523 of the hook portion 520 to prevent the elastic portion 400 and the hook portion 520 from moving continuously, so as to achieve the anti-falling effect.

Similarly, the stopper portion 510 may also prevent the elastic portion 400 from moving away from the release position along the width direction of the elastic portion 400. Specifically, the stopping portion 510 is disposed on the fixing portion 300 and located on one side of the elastic portion 400, and when the elastic portion 400 moves towards the side where the stopping portion 510 is disposed along the width direction of the elastic portion, the stopping portion 510 can prevent the elastic portion 400 from moving continuously, so as to achieve the anti-slip effect.

The elastic portion 400 further includes a second side 402 opposite to the first side 401, and the first side 401 is closer to the fixing portion 300. The protrusion 600 of the charging spring 30 is disposed on the second side 402 to contact the charging contact 110 of the audio device 10 when the elastic portion 400 is in the pressed position.

In this embodiment, through setting up boss 600 and trip portion 520 respectively at two mutually opposite first sides 401 and second sides 402 of elastic component 400, because charging elastic sheet 30 is when using, second side 402 is towards the charging contact 110 of audio equipment 10, first side 401 deviates from the charging contact 110 of audio equipment 10, so charging elastic sheet 30 of this application embodiment not only can play the backstop effect through setting up anticreep subassembly 500, can also avoid setting up of anticreep subassembly 500 to influence boss 600 and the normal contact of charging contact 110 of audio equipment 10.

The fixing part 300 includes a vertical section 310 and a horizontal section 320. The vertical section 310 and the horizontal section 320 may be of a unitary structure and formed by bending.

The stopping portion 510 may be disposed on the vertical section 310, for example, the side of the vertical section 310 is provided with a notch 312, and the stopping portion 510 is disposed in the notch 312. The stopping portion 510 and the vertical section 310 may be an integral structure, and the plane of the stopping portion 510 is perpendicular to the plane of the vertical section 310. Of course, the stop 510 may also be disposed at the horizontal segment 320. The elastic part 400 is connected to an end of the vertical section 310 away from the horizontal section 320.

The fixing portion 300 further includes a first clamping structure 311, and the first clamping structure 311 may be disposed on the vertical section 310, for example, near the notch 312. The first latch structure 311 can be latched with a second latch structure (not shown) of the charging box 20.
