On this basis, by providing the cover 8, dust and other foreign objects can be prevented from falling into the earphone insertion slot 11.

The charging stand also includes a driving assembly 4 and a charging male plug 5, both of which are arranged in the housing 1. The charging male plug 5 is fixedly connected to the output end of the driving assembly 4 and is electrically connected to the circuit board 2. A charging through hole 12 is also provided on the housing 1, and the driving assembly 4 can drive the charging male plug 5 to extend out of the charging through hole 12. By providing a charging male plug 5 electrically connected to the circuit board 2, the connection of the charging cable can be omitted when charging the charging stand, and the charging male plug 5 can be directly plugged into the charging port for charging, which reduces the cost and improves the convenience of use and carrying. On this basis, by providing a driving assembly 4, the charging male plug 5 is accommodated in the shell 1 in a non-charging state, and extends from the charging through hole 12 of the shell 1 in a charging state, which effectively protects the charging male plug 5, avoids the convex charging male plug 5 from being skewed and damaged under the action of external force, and improves the service life of the product.

In this embodiment, a power terminal is provided on the circuit board 2, and the power terminal extends into the earphone insertion slot 11. When the earphone 100 is accommodated in the earphone insertion slot 11, it is connected to the power terminal circuit, and then the circuit board 2 controls the battery 3 to charge the earphone 100. When the power of the battery 3 is insufficient, the charging male plug 5 is controlled to extend from the charging through hole 12, and then the charging male plug 5 is plugged into the charging interface of the charger to achieve charging of the battery 3. Among them, on the basis of the circuit board 2, the charging of the earphone 100 by the battery 3 and the charging of the battery 3 by the external power supply through the charging male plug 5 are both conventional settings in the field. The circuit structure and control principle are not repeated here, and the conventional settings can be referred to.

The driving assembly 4 includes a motor 41, a screw 42 and a support block 43. The motor 41 is fixed in the housing 1 and electrically connected to the circuit board 2. One end of the screw 42 is connected to the output shaft of the motor 41. The motor 41 can drive the screw 42 to rotate around its own axis. The support block 43 is slidably arranged in the housing 1 and screwed to the screw 42. The charging male connector 5 is arranged on the support block 43. By controlling the forward and reverse rotation of the motor 41, and then by the cooperation between the screw 42 and the support block 43, the charging male connector 5 is driven to extend or retract. The control process is simple and the transmission structure is safe and reliable.

The driving assembly 4 further includes a guide rib 44, which is disposed on the circuit board 2, and a support block 43 is slidably disposed on the guide rib 44. Through the sliding cooperation between the guide rib 44 and the support block 43, the structure is simplified, and the support block 43 can slide smoothly relative to the circuit board 2.

In this embodiment, the motor 41 is also fixed on the circuit board 2, simplifying the structure, and two guide ribs 44 are arranged on the circuit board 2 in parallel and at intervals, and two guide grooves are arranged on the support block 43. The two guide ribs 44 are correspondingly inserted into the two guide grooves, so that the support block 43 can slide more smoothly on the circuit board 2.

The charging stand further includes a control module 6, which is disposed on the outer wall of the housing 1. The drive assembly 4 and the control module 6 are electrically connected to the circuit board 2, respectively, and the control module 6 is configured to control the action of the drive assembly 4. By providing the control module 6, it is convenient for the user to control the drive assembly 4.

The control module 6 is a button. When the button is pressed twice adjacently, one press is used to trigger the charging male connector 5 to extend from the charging through hole 12, and the other press is used to trigger the charging male connector 5 to retract into the charging through hole 12. The above arrangement simplifies the steps of the control operation, so that the user only needs to press the control module 6.

In this embodiment, the control module 6 can control the extension and retraction of the charging male plug 5 by controlling the forward and reverse rotation of the motor 41. Among them, the control module 6 controls the motor 41 according to the conventional setting in the field, and the circuit structure and control principle are not repeated here, and can refer to the conventional setting. In addition, in addition to being set as a button, the control module 6 can also be set as a knob, and the knob can be switched and twisted between two positions. When the knob is twisted to one position, the charging male plug 5 is extended, and when the knob is twisted to the other position, the charging male plug 5 is retracted. It can also be set as a touch control screen to control the extension or retraction of the charging male plug 5 by operating the options on the screen.

The charging stand further includes a fixing member 7, which is connected to the housing 1. The housing 1 can be fixed at a setting position, such as a desktop, a surface of an electrical device, etc., through the fixing member 7, so that the earphone 100 can be more stably inserted into the housing 1 for charging.

The fixing member 7 includes a vacuum suction cup, and the housing 1 can be fixed at the setting position by adsorption of the vacuum suction cup.

In this embodiment, two vacuum suction cups are arranged side by side on the housing 1, thereby increasing the reliability of the housing 1 being adsorbed and fixed. In addition to the vacuum suction cup, the fixing member 7 may also include other detachable connecting parts such as Velcro and magnet.

The housing 1 is a rectangular block structure, and the earphone insertion slots 11 are arranged at the top of the housing 1, and two earphone insertion slots 11 are symmetrically arranged and configured to insert a pair of earphones 100. The fixing member 7 is arranged at the bottom of the housing 1, and the control module 6 and the charging through hole 12 are respectively arranged on two opposite side walls of the housing 1, thereby avoiding mutual interference.

The housing 1 includes a bottom plate and an upper housing clamped on the bottom plate. The bottom plate and the upper housing are arranged to form an inner cavity. The circuit board 2, the battery 3, the drive assembly 4 and the charging male plug 5 are all located in the inner cavity. The battery 3 is sandwiched between the circuit board 2 and the bottom plate. The drive assembly 4 and the charging male plug 5 are located on the side of the circuit board 2 away from the battery 3. The earphone insertion slot 11 and the charging through hole 12 are opened on the upper housing.

On the cover 8 and the housing 1, one is provided with a sliding joint 81, and the other is provided with a sliding groove 13, and the sliding joint 81 is slidably arranged in the sliding groove 13. The above arrangement enables the cover 8 to be flexibly adjusted relative to the housing 1 to selectively open or cover the earphone insertion slot 11.

The cover 8 includes a cover plate and a connecting plate. The cover plate is configured to cover the notch of the earphone insertion slot 11. The connecting plates are perpendicular to the cover plate and are provided in two pieces. The two connecting plates are respectively connected to the two ends of the cover plate. A sliding joint 81 is provided on each connecting plate. The two opposite side walls of the housing 1 are respectively provided with sliding grooves 13. The two sliding joints 81 are slidably provided in the two sliding grooves 13 in a one-to-one manner. The above arrangement enables the cover 8 to be connected to the housing 1 and to slide relative to the housing 1.

The end of the sliding groove 13 is connected to the positioning groove 14, and when the sliding joint 81 moves into the positioning groove 14, the cover 8 can rotate relative to the housing 1. The above arrangement enables the cover 8 to rotate relative to the housing 1, avoiding the cover 8 being in a suspended state, and making the adjustment of the cover 8 safer and more reliable.

In the open state, the cover 8 opens the notch of the earphone insertion slot 11 and covers the control module 6. The above arrangement allows the cover 8 to cover the control module 6 in the open state, thereby preventing the control module 6 from being accidentally touched when the charging stand charges the earphone 100 thereon in the open state.

In this embodiment, the sliding groove 13 is on the shell 1, extending in the front-to-rear direction from the charging through hole 12 to the control module 6, the positioning groove 14 is arranged at the end of the sliding groove 13 facing the control module 6, and the sliding joint 81 is arranged at the end of the connecting plate facing the charging through hole 12. When the sliding joint 81 slides into the positioning groove 14, the cover 8 opens the notch of the earphone insertion slot 11, and then the cover 8 rotates downward under the action of its own gravity to the placement surface against the charging seat. At this time, the position and orientation of the cover 8 are safer and more reliable, and can assist in supporting the shell 1 to prevent the shell 1 from tipping over.

The charging stand also includes a working indicator light 9, which is arranged on the outer wall of the housing 1 and electrically connected to the circuit board 2. By arranging the working indicator light 9, the working state of the charging stand can be indicated.

The working indicator light 9 is arranged at the top of the housing 1, between the two earphone insertion slots 11.

In this embodiment, the charging stand has a foolproof function. When the earphone 100 is inserted upside down in the earphone insertion slot 11, the working indicator light 9 sends a first prompt signal. When the power of the battery 3 is lower than the first set value and needs to be charged, the working indicator light 9 sends a second prompt signal. When the battery 3 in the charging stand is fully charged, the working indicator light 9 sends a third prompt signal. When the charging stand fully charges the earphone 100 thereon, the working indicator light 9 sends a fourth prompt signal. Among them, the first prompt signal, the second prompt signal, the third prompt signal and the fourth prompt signal are different, and are different light colors and/or flashing frequencies. The setting principle and triggering working steps of each prompt signal of the above-mentioned working indicator light 9 are conventional settings in this field and will not be repeated here.

The working process of the charging stand of the present invention is as follows: When charging the earphone 100: Step 1, fix the housing 1 on the placement surface through the fixing member 7. Step 2, slide open the cover 8, open the notch of the earphone insertion slot 11 on the housing 1, and then the cover 8 rotates downward under its own gravity to the placement surface against the charging stand. Step 3, put the earphone 100 into the earphone insertion slot 11 for charging. When charging the charging stand itself: Step 1, press the control module 6, drive the assembly 4 to move, and drive the charging male plug 5 to extend from the charging through hole 12. Step 2, insert the charging male plug 5 into the charging port for charging. Step 3: After charging is completed, pull out the charging male plug 5 from the charging port. Step 4: Press the control module 6 again to drive the assembly 4 to move and drive the charging male plug 5 back into the charging through hole 12.
