[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] As Figures 1 to 6The earphone charging box of the elevatable earphone shown comprises a box body 1, a charging bin 3 arranged in the box body 1, a placement cavity 31 for placing an earphone 8 arranged in the charging bin 3, and an upper cover 2 for sealing the charging bin 3 in cooperation with the box body 1, and comprises an elevating assembly 4 axially movable along the charging bin 3, the elevating assembly 4 comprising an elevating plate 41 and an abutting column 43, a through hole 3121 being arranged on the bottom 312 of the placement cavity, the abutting column 43 penetrating the through hole 3121 into the inside of the placement cavity 31 and abutting against the bottom of the earphone 8, the upper cover 2 being opened, the upper cover 2 cooperating with the elevating plate 41 to drive the elevating assembly 4 to move upwards and make the abutting column 43 push out the earphone 8, the elevating assembly 4 and the charging bin 3 being provided with an elastic member 5, the upper cover 2 being closed, the elastic member 5 driving the elevating assembly 4 to move downwards. After the structure of the utility model is adopted, because the elevating assembly 4 is arranged and the elevating assembly 4 is provided with the abutting column 43, when the upper cover 2 is opened, the upper cover 2 cooperates with the elevating plate 41 in the elevating assembly 4 to drive the elevating assembly 4 to move upwards and make the abutting column 43 push out the earphone 8 in the charging bin 3, the elastic member 5 is arranged between the charging bin 3 and the elevating assembly 4, when the upper cover 2 is closed, the elastic member 5 drives the elevating assembly 4 to move downwards, therefore when the upper cover 2 is opened, the earphone 8 can be pushed out, the problem that the earphone 8 is not easily taken out due to hand slip is solved, a better experience is provided for the user, and the structure is simple and the failure rate is low.

[0029] As a specific embodiment rather than a limitation, in order to make the upper cover 2 drive the elevating assembly 4 to move upwards when the upper cover 2 is opened, one end of the elevating plate 41 is extended and provided with a first flap 44, the upper cover 2 is provided with a second flap 21, and the first flap 44 abuts against the second flap 21 when the upper cover 2 is opened. The upper cover 2 is hinged to the charging bin 3, the charging bin 3 is fixed in the box body 1, the upper cover 2 can swing relative to the charging bin 3, the hinge of the upper cover 2 serves as a fulcrum when the upper cover is opened, at this time, the second flap 21 arranged on the upper cover 2 abuts against the first flap 44 on the elevating assembly 4, the second flap 21 props the first flap 44, so that the elevating assembly 4 rises and the abutting column 43 pushes out the earphone in the charging bin 3.

[0030] In another embodiment, one of the upper cover 2 and the elevating assembly 4 is provided with a tooth, and the other is provided with a rack, the tooth cooperates with the rack in the process of opening the upper cover 2, drives the elevating assembly 4 to move upwards, and makes the abutting column 43 push out the earphone from the placement cavity 31.

[0031] Further, in order to make the lifting assembly 4 move stably along the charging bin 3, the lifting plate 41 is provided with a limiting opening 411, the charging bin 3 is fixedly provided with a first limiting plate 32, the first limiting plate 32 is inserted into the limiting opening 411, and the lifting plate 41 can move axially relative to the first limiting plate 32. The first limiting plate 32 can be inserted into the limiting opening 411, at this time, the side wall of the first limiting plate 32 cooperates with the inner wall of the limiting opening 411 to limit, so that the lifting plate 41 can only move axially relative to the first limiting plate 32. Alternatively, the first limiting plate 32 is a T-shaped structure, one side of which is inserted into the limiting opening 411, and the other side abuts against the limiting opening 411 to fix the lifting plate 41, so as to prevent the lifting plate 41 from separating from the charging bin 3. In this embodiment, a lubricant can also be added between the first limiting plate 32 and the lifting plate 41, so as to prevent excessive friction and serious wear when the lifting plate 41 moves relative to the first limiting plate 32.

[0032] As a specific embodiment but not limitation, in order to prevent the lifting plate 41 from exceeding the stroke when moving relative to the first limiting plate 32, the inner wall of the limiting opening 411 cooperates with the side wall of the first limiting plate 32 to limit the movement of the lifting plate 41 relative to the first limiting plate 32 when the lifting plate 41 moves axially relative to the first limiting plate 32. The length of the first limiting plate 32 is smaller than the length of the limiting opening 411, so the lifting plate 41 can move relative to the first limiting plate 32. When moving, the inner wall of the limiting opening 411 cooperates with the side wall of the first limiting plate 32 to limit the movement of the lifting plate 41 relative to the first limiting plate 32.

[0033] Further, in order to make the abutting column 43 accurately inserted into the placement cavity 31 to push out the earphone 8, the lifting plate 41 is provided with a support plate 42 away from the first lifting plate 44, the abutting column 43 is fixed on the support plate 42, the charging bin 3 is provided with a guide hole 34, and the support plate 42 is further provided with an insertion column 45 which is inserted into the guide hole 34. Since the abutting column 43 is arranged on the support plate 42 and parallel to the insertion column 45, and the insertion column 45 is inserted into the guide hole 34, the guide hole 34 plays a guiding role during the lifting or lowering of the lifting assembly 4, so that the abutting column 43 is accurately inserted into the placement cavity 31 to push out the earphone.

[0034] As a specific embodiment rather than a limitation, in order to smoothly lower the lifting assembly 4 when the upper cover 2 is closed, the elastic member 5 is sleeved on the insertion column 45, one end of the elastic member 5 abuts against the support plate 42, and the other end abuts against the charging compartment 3. The elastic member 5 is a spring, and the maximum stroke of the spring is greater than the distance from the charging compartment 3 to the support plate 42. When the upper cover 2 is closed, the lifting assembly 4 will not be subjected to an upward force because the first flap 44 does not abut against the second flap 21. Therefore, the elastic force of the spring can easily drive the lifting assembly 4 to move downward, thereby achieving automatic resetting of the lifting assembly 4.

[0035] Further, in order to charge the earphone 8, the charging compartment 3 is provided with a fixing column 33, and the charging assembly 6 is fixedly arranged on the fixing column 33. The fixing column 33 is arranged at the bottom of the charging compartment 3.

[0036] As a specific embodiment rather than a limitation, in order to prevent the abutting column 43 from damaging the terminal when the earphone 8 is pushed out, the placement cavity 31 includes a placement cavity side wall 311 and a placement cavity bottom 312, and a bending portion 313 is arranged between the placement cavity side wall 311 and the placement cavity bottom 312. The charging port 35 is arranged on the bending portion 313, and the placement cavity 31 is in communication with the outside through the charging port 35. In a TWS earphone, the charging terminal of most earphones is arranged at the bottom of the earphone. When the abutting column 43 pushes out the earphone 8, the earphone terminal is easily damaged. Therefore, a terminal port needs to be arranged on the side of the earphone to prevent the earphone terminal from being damaged in the case of repeated use, so that the earphone cannot be charged. The charging port 35 is arranged on the bending portion 313. This position can not only prevent the abutting column 43 from directly contacting the earphone terminal when the earphone is pushed out, thereby damaging the earphone terminal, but also prevent the connecting terminal 62 from being damaged due to friction with the earphone 8 when the connecting terminal 62 is arranged on the side wall of the placement cavity 31.

[0037] Further, in order to make the earphone 8 terminal contact the connecting terminal 62 more stably, the charging assembly 6 includes a circuit board 61 and a connecting terminal 62 arranged on the circuit board 61. The connecting terminal 62 is provided with a terminal rack 622, and terminal springs 621 are arranged between the terminal racks 622. One end of the terminal spring 621 penetrates through the charging port 35. The terminal spring 621 is a structure with elasticity. When the earphone is placed into the placement cavity 31, the terminal spring 621 will always abut against the earphone terminal due to the elasticity and good conductivity of the terminal spring 621. Therefore, the contact is good, and phenomena such as poor contact will not occur, and the charging is more stable.

[0038] As a specific implementation and not a limitation, to prevent the end clip 621 from detaching from the terminal frame 622, a second limiting plate 6221 is provided at the end of the terminal frame 622 near the charging port 35. The end clip 621 extends with a terminal limiting block 6211. The second limiting plate 6221 cooperates with the terminal limiting block 6211 to limit the end clip 621 from excessively inserting into the charging port 35. When no external force is applied, the end clip 621 has a certain elasticity. Under the action of this elasticity, the end of the end clip 621 tends to move away from the terminal frame 622. Therefore, the terminal limiting block 6211 provided on the end clip 621 abuts against the second limiting plate 6221 provided on the terminal frame 622, preventing the end clip 621 from excessively inserting into the charging port 35.

[0039] As a specific implementation and not a limitation, to prevent the earphones 8 from easily falling out when placed inside the charging case 31, and to prevent the earphones 8 from colliding inside the charging case when the case is closed, the charging case 3 is equipped with a magnetic component 7. The magnetic component 7 is attracted and fixed to the magnet on the earphones 8. The magnetic component 7 on the charging case 3 is a magnet, which uses the principle of attraction between opposite poles of magnets to achieve attraction and fixation.

[0040] The specific working principle of this utility model is as follows:

[0041] like Figure 7 As shown, when the top cover 2 is opened, the top cover 2, which is hinged to the charging compartment 3, will rotate. The second rocker plate 21 of the top cover 2 will abut against the first rocker plate 44 on the lifting assembly 4. Subsequently, as the top cover 2 continues to open, as... Figure 8 As shown, the second rocker arm 21 lifts the first rocker arm 44, causing the lifting assembly 4 to rise. The abutment post 43, located at the bottom of the charging case 3, then inserts into the placement cavity 31 to push out the earphone 8, making it easier for the user to remove the earphone. Figure 9 As shown, when the top cover 2 is closed, since the elastic element 5 is sleeved on the insertion post 45, one end of the elastic element 5 abuts against the charging case 3, and the other end abuts against the support plate 42 on the lifting assembly 4, the elastic element 5 will cause the lifting assembly 4 to move down due to the elastic force, thereby causing the abutment post 43 to exit the placement cavity 31. At the same time, the magnet on the earphone attracts the magnetic element 7 on the charging case 3, fixing the earphone 8 in the placement cavity 31. Meanwhile, the connection terminal 62 of the charging assembly 6 enters the placement cavity 31 through the charging port 35 and abuts against the charging terminal on the bottom side wall of the earphone 8 to charge the earphone 8.

[0042] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
