[0051] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0052] Example 1

[0053] This embodiment provides a wireless Bluetooth earphone charging case, such as Figures 1 to 3As shown, the wireless Bluetooth earphone charging case includes a charging case assembly and two cover assemblies. One of the cover assemblies 2 is detachably disposed on the top of the charging case assembly, and the other cover assembly 2 is detachably disposed on the bottom of the charging case assembly. Both cover assemblies 2 include a battery 23. An earphone compartment 4 for accommodating Bluetooth earphones 100 is formed between the cover assembly 2 located at the top of the charging case assembly and the charging case assembly. The battery 23 located at the bottom of the charging case assembly is electrically connected to the charging case assembly.

[0054] In detail, when the Bluetooth earphone 100 needs to be charged, it is placed in the earphone case 4. The battery 23 located in the cover assembly 2 at the bottom of the charging case assembly powers the Bluetooth earphone 100. When the battery 23 in the cover assembly 2 at the bottom of the charging case assembly is low on power, the top and bottom cover assemblies 2 of the charging case assembly can be interchanged to continue charging the Bluetooth earphone 100. This doubles the power reserve capacity, improves battery life, and enhances the user experience.

[0055] The wireless Bluetooth earphone charging case includes a main housing 1 and a charging assembly 3. The charging assembly 3 includes a main circuit board 31 and a first charging terminal 32. The main circuit board 31 is disposed inside the main housing 1, and the first charging terminal 32 is disposed in the main housing 1 and electrically connected to the main circuit board 31. The cover assembly 2 also includes a second charging terminal 24, which is electrically connected to a battery 23. The second charging terminal 24, located at the bottom of the main housing 1, is electrically connected to the first charging terminal 32 to charge the Bluetooth earphone 100 inside the earphone compartment 4 using the battery 23 at the bottom of the main housing 1.

[0056] like Figure 1 , Figure 3 and Figure 4 As shown, the charging assembly 3 also includes a charging interface 35, which is disposed on the main housing 1 and electrically connected to the main circuit board 31. It is understood that the charging interface 35 can be connected to a power source via a charger, thereby enabling the charging of the Bluetooth headset 100 located in the earphone compartment 4 or the battery 23 located at the bottom of the main housing 1.

[0057] In this embodiment, preferably, the first charging terminal 32 is arc-shaped, and the second charging terminal 24 is plate-shaped, with the second charging terminal 24 located at the bottom of the main housing 1 abutting against the first charging terminal 32. It is understood that the arc shape of the first charging terminal 32 allows it to have a certain degree of elasticity, thereby enabling a more reliable connection between the first charging terminal 32 and the second charging terminal 24. Furthermore, when the cover assembly 2 is connected to the bottom of the main housing 1, the second charging terminal 24 can directly abut against the first charging terminal 32, achieving an electrical connection between the two terminals and facilitating easier connection and disassembly of the cover assembly 2 and the main housing 1. Of course, in other embodiments, those skilled in the art can also set the first charging terminal 32 and the second charging terminal 24 in other forms, which are not limited here.

[0058] In some alternative embodiments, such as Figure 1 and Figure 3 As shown, the cover assembly 2 also includes an outer cover 21 and an inner liner 22. The inner liner 22 is disposed inside the outer cover 21, and the battery 23 is disposed between the bottom wall of the inner liner 22 and the bottom wall of the outer cover 21. The second charging terminal 24 is disposed in the inner liner 22. Specifically, the second charging terminal 24 is disposed at the end of the inner liner 22 that is connected to the main housing 1, which facilitates both the fixing of the second charging terminal 24 and the connection between the second charging terminal 24 and the first charging terminal 32.

[0059] like Figure 3 As shown, the inner liner 22 has a mounting hole 221 on the side opposite to the outer cover 21, and the second charging terminal 24 is disposed in the mounting hole 221. By providing the mounting hole 221, the second charging terminal 24 can be exposed on the cover assembly 2, so as to connect with the first charging terminal 32, and at the same time, it is also convenient for the second charging terminal 24 to connect with the battery 23 through the mounting hole 221.

[0060] To facilitate the connection between the cover assembly 2 and the main housing 1, such as Figures 2 to 5 As shown, at the connection end between the cover assembly 2 and the main housing 1, the inner liner 22 protrudes from the outer cover 21. The outer wall of the portion of the inner liner 22 protruding from the outer cover 21 is tapered. The top and bottom of the main housing 1 both have slots 11 that mate with and insert into the inner liner 22. Specifically, the slots 11 are shaped like flared openings, so that when the cover assembly 2 and the main housing 1 are connected, the inner liner 22 can be easily inserted into the slots 11, thus facilitating the connection between the cover assembly 2 and the main housing 1.

[0061] like Figure 1 and Figure 3As shown, the main housing 1 includes an outer shell 12, a top cover 13, and a bottom cover 14. The outer shell 12 is open at both ends. The top cover 13 is located inside the outer shell 12 and at the top of the outer shell 12, forming an earphone compartment 4 between it and the cover assembly 2. The bottom cover 14 is located inside the outer shell 12 and at the bottom of the outer shell 12. The main circuit board 31 is located between the top cover 13 and the bottom cover 14. The first charging terminal 32 is located on the bottom cover 14, and the bottom cover 14 has a clearance hole 141 corresponding to the first charging terminal 32, so that the first charging terminal 32 can be connected to the second charging terminal 24 through the clearance hole 141. Through the arrangement of the top cover 13 and the bottom cover 14, the top and bottom of the main housing 1 can be connected to the cover assembly 2, realizing the interchangeability of the positions of the two cover assemblies 2.

[0062] Furthermore, one end of the first charging terminal 32 is fixed to the bottom cover 14 by a fixing plate 34. Specifically, the first terminal is sandwiched between the fixing plate 34 and the bottom cover 14, so that the first charging terminal 32 can be reliably fixed. The other end of the first charging terminal 32 extends into the clearance hole 141 to realize the connection with the second charging terminal 24.

[0063] In detail, such as Figure 4 and Figure 5 As shown, a first groove 222 that partially matches the Bluetooth headset 100 is formed in the inner liner 22, and a second groove 131 that partially matches the Bluetooth headset 100 is formed in the top cover 13. When the main housing 1 and the cover assembly 2 are connected, the first groove 222 and the second groove 131 form the earphone compartment 4.

[0064] like Figure 1 and Figure 4 As shown, this embodiment also includes a fixing component 5, which includes a first connecting structure 51, a second connecting structure 52, and a third connecting structure 53. The first connecting structure 51 and the second connecting structure 52 are respectively disposed on the top and bottom of the charging compartment assembly. Each cover assembly 2 is provided with a third connecting structure 53. One cover assembly 2 is connected to the top of the main housing 1 through the third connecting structure 53, the first connecting structure 51, and the other cover assembly 2 is connected to the bottom of the charging compartment assembly through the third connecting structure 53, the second connecting structure 52, and the third connecting structure 53. It is understood that when the cover assembly 2 is placed on the top of the charging compartment assembly, the cover assembly 2 and the charging compartment assembly are fixed by connecting the third connecting structure 53 and the second connecting structure 52. When the cover assembly 2 is placed on the bottom of the charging compartment assembly, the cover assembly 2 and the charging compartment assembly are fixed by connecting the third connecting structure 53 and the second connecting structure 52.

[0065] Specifically, the first connecting structure 51 includes at least one first magnetic member 511, which is disposed on the top of the main housing 1. The second connecting structure 52 includes at least one second magnetic member 521, which is disposed on the bottom of the charging case assembly. The third connecting structure 53 includes at least one third magnetic member 531, which is disposed on the cover assembly 2. The third magnetic member 531 is capable of attracting either the first magnetic member 511 or the second magnetic member 521. In some optional embodiments, the first magnetic member 511 and the second magnetic member 521 are magnets, and the third magnetic member 531 is a magnet. The connection between the cover assembly 2 and the top of the main housing 1 is achieved by the attraction of the first magnetic member 511 and the third magnetic member 531, and the connection between the cover assembly 2 and the bottom of the charging case assembly is achieved by the attraction of the second magnetic member 521 and the third magnetic member 531. Of course, in other embodiments, those skilled in the art can also make the first magnetic 511 and the second magnetic 521 as magnets, and the third magnetic 531 as a ferromagnetic material, or make the third magnetic 531 as a magnet, and the first magnetic 511 and the second magnetic 521 as ferromagnetic materials. No limitation is imposed here. Preferably, in this embodiment, two first magnetic 511s are provided, each located at one of the two opposite corners of the top of the main housing 1. Correspondingly, two second magnetic 521s are provided, each located at one of the two opposite corners of the bottom of the main housing 1. Two third magnetic 531s are provided, each located at one of the two opposite corners of the connecting end of the cover assembly 2. This saves materials and ensures a stable connection between the cover assembly 2 and the main housing 1.

[0066] Example 2

[0067] The working principle of the wireless Bluetooth earphone charging case in this embodiment is basically the same as that in Embodiment 1, with the specific differences being, as follows: Figures 6 to 9 As shown, the charging assembly 3 also includes a sub-circuit board 33 disposed in the main housing 1. The sub-circuit board 33 is electrically connected to the main circuit board 31. There are two first charging terminals 32. The two first charging terminals 32 are respectively disposed at the top and bottom of the main housing 1 and are electrically connected to the sub-circuit board 33. Each first charging terminal 32 is electrically connected to a second charging terminal 24 to charge the two batteries 23 simultaneously.

[0068] In detail, when no external power source is connected, the Bluetooth headset 100 is charged via the main circuit board 31 and the battery 23 located at the bottom of the main housing 1. When an external power source is connected, the Bluetooth headset 100 located in the earphone compartment 4, the battery 23 located at the top of the main housing 1, and the battery 23 located at the bottom of the main housing 1 can be charged simultaneously. The configuration of the main circuit board 31 and the secondary circuit board 33 is mature existing technology and is not limited here.

[0069] Furthermore, such as Figures 7 to 9 As shown, the third connection structure 53 includes a button 532, a mounting base 533, and an elastic element 534. The button 532 slides through the side wall of the cover assembly 2. The mounting base 533 is disposed inside the cover assembly 2 and connected to the button 532. The elastic element 534 is disposed inside the cover assembly 2, with one end connected to the mounting base 533 and the other end connected to the cover assembly 2. Both the first connection structure 51 and the second connection structure 52 include a socket 54 on the charging case assembly corresponding to the position of the button 532. When the charging case assembly and the cover assembly 2 are connected, the mounting base 533 is at least partially inserted into the socket 54 and can abut against the side wall of the charging case assembly. Pressing the button 532 can separate the mounting base 533 from the side wall of the charging case assembly to separate the charging case assembly and the cover assembly 2. Specifically, button 532 slides through the side wall of outer cover 21 and the side wall of inner liner 22, and socket 54 is opened on the side wall of top cover 13. Mounting base 533 can pass through socket 54 and abut against housing 12. When button 532 is pressed, mounting base 533 and housing 12 can be separated, thereby separating cover assembly 2 and charging case assembly.

[0070] In detail, there are two third connection structures 53, which are respectively located on opposite sides of the cover assembly 2. This allows the two mounting seats 533 to abut against the side wall of the charging compartment assembly from the inside out, thereby stably connecting the charging compartment assembly and the cover assembly 2.

[0071] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
