A plurality of first magnetic blocks 3 are embedded at the bottom of the upper cover 1, and a second magnetic block 4 corresponding to the first magnetic block 3 is embedded at the top of the base 2. The same ends of the first magnetic block 3 and the second magnetic block 4 face each other. A locking structure 5 is provided between the upper cover 1 and the base 2, and the upper cover 1 and the base 2 can be locked or unlocked by the locking structure 5.

[0027] Its working principle is to put the upper cover 1 on the upper body of the earphone charging case, and put the base 2 on the lower body of the earphone charging case. By setting a locking structure 5 between the upper cover 1 and the base 2, the upper cover 1 and the base 2 can be locked, thereby improving the closed positioning effect between the upper cover 1 and the base 2, and preventing the earphone protective case from automatically opening when it falls to the ground, thereby better protecting the earphone; since the bottom of the upper cover 1 and the top of the base 2 are correspondingly provided with the first magnetic block 3 and the second magnetic block 4 with the same polarity, a repulsive force will be generated between the first magnetic block 3 and the second magnetic block 4. When the upper cover 1 and the base 2 are unlocked by the locking structure 5, the upper cover 1 will be opened from the base 2 driven by the repulsive force between the first magnetic block 3 and the second magnetic block 4, and the earphone charging case will be automatically opened without the need to manually lift the upper cover. It has a better sense of technology and user experience, and is worthy of popularization and use.

[0028] Based on the above embodiment, first receiving grooves 10 matching the first magnetic block 3 are symmetrically arranged on both sides of the bottom of the upper cover 1, and the first magnetic block 3 is arranged in the first receiving groove 10. Second receiving grooves 20 matching the second magnetic block 4 are symmetrically arranged on both sides of the top of the base 2, and the second magnetic block 4 is arranged in the second receiving groove 20, so that the installation and positioning of the first magnetic block 3 and the second magnetic block 4 can be realized.

[0029] Reference Figure 1-5, which is a form of a locking structure. The locking structure 5 comprises a key slide 50 arranged on the outer side of the base 2, a push-type key 51 slidably connected to the key slide 50 in the horizontal direction, and a return spring 52. A first card plate 11 is arranged on the outer side of the upper cover 1, a second card plate 510 is arranged on the inner side of the push-type key 51, a first avoidance groove 500 corresponding to the first card plate 11 is arranged on the top wall of the key slide 50, a second avoidance groove 21 communicating with the inside of the key slide 50 is arranged on the side wall of the base 2, the first avoidance groove 500 and the second avoidance groove 21 are connected, a limiting plate 501 connected to the outer wall of the base 2 is arranged on the inner side wall of the key slide 50, a spring receiving groove 511 is arranged on the inner side wall of the push-type key 51, and the return spring 52 is arranged in the spring receiving groove 511 and abuts between the limiting plate 501 and one end wall of the spring receiving groove 511. Specifically, when it is necessary to open the earphone protective case, the push button 51 is toggled to move along the button slide groove 50 to compress the reset spring 52. When the second locking plate 510 is staggered with the first locking plate 11, the upper cover 1 and the base 2 are unlocked, and the upper cover 1 will automatically open from the base 2 under the drive of the repulsive force between the first magnetic block 3 and the second magnetic block 4. When the upper cover 1 is opened, the second avoidance groove 21 and the first avoidance groove 500 can avoid the first locking plate 11, and there is no need to manually open the upper cover 1; after the upper cover 1 and the base 2 are closed, the push button 51 will be reset along the button slide groove 50 under the elastic force of the reset spring 52, and the first locking plate 11 is blocked by the second locking plate 510, thereby realizing the locking function between the upper cover 1 and the base 2. The upper cover 1 cannot be opened under the drive of the repulsive force between the first magnetic block 3 and the second magnetic block 4, thereby avoiding the earphone protective case from automatically opening when it falls to the ground, thereby better protecting the earphone.

[0030] Based on the above embodiment, horizontal guide grooves 512 are provided on the upper and lower wall surfaces of the push-type button 51, and horizontal guide strips 502 matching the horizontal guide grooves 512 are provided on the upper and lower wall surfaces of the button slide groove 50.
