[0002] Most headphones typically come with a charging case, such as wireless headphones. Taking wireless headphones as an example, the charging case is an essential accessory when purchasing headphones, providing storage and charging functions for wireless headphones.

[0003] In existing technology, earphones are firmly attached to the charging case for charging due to the magnetic structure. Since earphones are usually handled by hand, the oil on the hands makes the surface of the earphones slippery. When the earphones are pulled out of the earphone case, the contact area between the fingers and the earphones is small, which makes the earphones easy to fall out of the hand and easily damage the internal components of the earphones. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an earphone charging case that solves the problem that in existing technologies, earphones are firmly attracted to the charging case for charging due to their magnetic structure. However, since earphones are generally handled by hand, and hands are somewhat oily, making the earphone surface slippery, the contact area between the fingers and the earphones is small when removing the earphones from the case. This results in the earphones easily falling out of the hand, which can easily damage the internal components of the earphones.

[0028] Please see Figures 1 to 4The image shows an earphone charging case according to the first embodiment of the present invention, including a case body. The case body includes a charging part 11 and a cover part 12 rotatably connected to the charging part 11. The charging part 11 is provided with a charging port 13 for inserting earphones. The bottom of the charging port 13 is provided with a lifting assembly. The lifting assembly includes a pin 20 located inside the charging part 11 and passing through the charging port 13, and a lifting structure for driving the pin 20 to lift. The edge of the charging port 13 is provided with an elastic structure 14 to restrict the earphone from falling. The interface between the charging part 11 and the cover part 12 is provided with a contact module 16 for controlling the lifting structure to lift the pin 20. The cover part 12 is disengaged from the charging part 11, and the contact module 16 is released from compression to control the lifting structure to lift the pin 20.

[0029] Understandably, this utility model provides a lifting component at the bottom of the charging port 13. The lifting component includes a pin 20 located inside the charging part 11 and passing through the charging port 13, and a lifting structure that drives the pin 20 to lift. Then, a contact module 16 is provided at the interface between the charging part 11 and the cover part 12 to control the lifting structure to lift the pin 20. When the user opens the cover part 12, the cover part 12 is disconnected from the charging part 11, and the contact module 16 is released from the pressure. A signal is sent to the contact module 16 so that the contact module 16 controls the lifting structure to lift the pin 20. When the earphone is lifted, it passes through the elastic structure 14, causing the elastic structure 14 to deform until the earphone is completely above the elastic structure 14. The elastic structure 14 then returns to its original position. At this time, the earphone is stuck on the elastic structure 14 due to gravity, preventing the earphone from being magnetically attracted back into the charging port 13.

[0030] This invention can prevent the earphones from easily falling out of your hand when you pull them out of the earphone case because the contact area between your fingers and the earphones is too small.

[0031] Preferably, the elastic structure 14 can be made of materials such as silicone or a soft pad.

[0032] Specifically, in this embodiment, the charging port 13 includes a first earphone head placement groove 131 recessed in the surface of the charging part 11 and an earphone stem placement groove 132 recessed in the first earphone head placement groove 131; the cover part 12 has a second earphone head placement groove 17 recessed in its surface, the second earphone head placement groove 17 is configured to cooperate with the first earphone head placement groove 131, and the accommodating space formed by the second earphone head placement groove 17 and the first earphone head placement groove 131 is used to place the earphone head.

[0033] Understandably, most wireless headphones nowadays have a stem and a headphone. The stem is used for holding and the headphone is used for sound. Therefore, a first headphone placement slot 131 and a second headphone placement slot 17 are provided to accommodate the headphone, and a stem placement slot 132 is provided to accommodate the stem.

[0034] Furthermore, the ejector pin 20 is provided with an actuating rod 21, and a first elastic element 22 is provided below the ejector pin 20. The lifting structure includes a shaped plate, a miniature telescopic rod 30, a connecting rod 32 connecting the miniature telescopic rod 30 and the shaped plate, and a second elastic element 31 sleeved on the connecting rod 32. The two ends of the second elastic element 31 are fixedly connected to the miniature telescopic rod 30 and the shaped plate, respectively. The shaped plate includes a straight rod 34, a triangular plate 36, and a connecting rod 35 connecting the straight rod 34 and the triangular plate 36. A receiving groove 40 for accommodating the actuating rod 21 is provided between the straight rod 34, the triangular plate 36, and the connecting rod 35. The triangular plate 36 has a wedge-shaped surface, and the straight rod 34 has a sliding hole 33 for the extension and retraction of the connecting rod 32.

[0035] Understandably, in the initial state of the first elastic member 22, the ejector pin 20 protrudes into the charging port 13. When the earphone is placed into the charging port 13, the earphone stem will press the ejector pin 20 downwards. The actuating lever 21 on the ejector pin 20 will press the triangular plate 36 along the wedge-shaped surface. The triangular plate 36 moves laterally, and the second elastic member 31 is pulled up until the actuating lever 21 is located in the receiving groove 40. The second elastic member 31 drives the straight rod 34 to reset. Since the actuating lever 21 is engaged in the receiving groove 40, the rebound of the first elastic member 22 can be limited. When the cover 12 is opened, the contact module 16 triggers the micro telescopic rod 30, which causes the micro telescopic rod 30 to move the irregular plate until the actuating lever 21 is disengaged from the receiving groove 40. Then, the ejector pin 20 pushes up and causes the earphone to pop out.

[0036] Preferably, there are two ejector pins 20, and the two ejector pins 20 are symmetrically arranged in the earphone stem placement groove 132.

[0037] Furthermore, a metal plate 133 is provided in the earphone stem placement slot 132, and the metal plate 133 is used to contact the earphone for charging; a hinge shaft 15 is provided on the side of the charging part 11 and the cover part 12 away from the contact module 16.

[0038] In summary, the earphone charging case in the above embodiments of this utility model has a lifting component at the bottom of the charging port. The lifting component includes a pin located inside the charging part and passing through the charging port, and a lifting structure for driving the pin to lift. A contact module for controlling the lifting structure to lift the pin is provided at the interface between the charging part and the cover. When the user opens the cover, the cover is disconnected from the charging part, and the contact module is released from the pressure to send a signal to the contact module, so that the contact module controls the lifting structure to lift the pin. When the earphone is lifted, it passes through the elastic structure, causing the elastic structure to deform until the earphone is completely above the elastic structure. The elastic structure then returns to its original position. At this time, the earphone is held in place by gravity on the elastic structure, preventing the earphone from being magnetically attracted back into the charging port.

[0039] This invention can prevent the earphones from easily falling out of your hand when you pull them out of the earphone case because the contact area between your fingers and the earphones is too small.
