[0002] Wireless earphones are usually equipped with an earphone charging box for storage, carrying and charging. Most of the earphones are placed in the symbol-shaped groove of the charging box and fixed with magnets. Manually open the charging box and take out the earphones. The earphones themselves are small in size and fit tightly with the charging box. When users take the earphones, they generally only grab the upper half of the earphones. The surface of the earphones is relatively smooth, which causes many inconveniences for users when taking the earphones. In this regard, it is known that a push mechanism is added to the charging box of the prior art. When the charging box is opened, the earphones are pushed out by the push mechanism, so that users can easily take out the earphones. However, since the push mechanism needs to occupy a certain installation space, it particularly affects the height of the charging box, resulting in a larger size of the charging box, which runs counter to the development direction of thinness, portability and miniaturization.

[0027] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0028] like Figures 1 to 7As shown, the present invention discloses a charging box 100, including a box cover 10, a box body 20 and a driving device 30. The box cover 10 is movably connected to the box body 20, and the box cover 10 can cover or open the box body 20. Preferably, the box cover 10 is rotatably connected to the box body 20, but is not limited to this. The box body 20 has a receiving cavity 21 for placing the device to be charged, and the driving device 30 is arranged in the box body 20. The driving device 30 includes a driving motor 31, a connecting component 32 and a pushing component 33 arranged in sequence along the length direction (also the left and right direction) of the charging box 100. The connecting component 32 is installed at the output end of the driving motor 31, and the pushing component 33 is connected to the connecting component 32. The driving motor 31 drives the pushing component 33 to rise upward through the connecting component 32 to push the device 01 to be charged out of the receiving cavity 21. The driving motor 31 drives the pushing assembly 33 to rise upward through the connecting assembly 32 , and after the device to be charged 01 is pushed out of the accommodating cavity 21 , the user can conveniently take the device to be charged 01 .

[0029] The driving device 30 of the present invention includes a driving motor 31, a connecting assembly 32 and a pushing assembly 33, and the driving motor 31, the connecting assembly 32 and the pushing assembly 33 are arranged in sequence along the length direction of the charging box 100. That is to say, the present invention arranges the driving device 30 in the length direction of the charging box 100, making full use of the space of the box body 20 in the length direction, avoiding affecting the height design of the charging box 100, thereby avoiding the volume of the charging box 100 from increasing.

[0030] The device to be charged 01 is placed in the accommodating cavity 21. After the charging box 100 is closed and powered on, the device to be charged 01 can be charged. When the charging box 100 is not powered on, the charging box 100 can also be used as a carrier for storing the device to be charged 01. The device to be charged 01 includes headphones, power banks, game consoles, etc. The present invention is described using wireless headphones as an example. The box cover 10 is flipped along the front-to-back direction (also the width direction) to open or close. Figure 1 The middle box cover 10 is in a closed state. Figure 2 The middle box cover 10 is in an open state. In the embodiment provided in the present invention, the wireless earphone is taken out along the height direction (also the up-down direction) of the box cover 10 .

[0031] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the box body 20 includes a shell 22 with an opening at the top and a mounting cavity 221, and a cover plate 23 mounted on the opening of the shell 22. A portion of the cover plate 23 extends into the mounting cavity 221, and the inner cavity of the portion of the structure forms a receiving cavity 21 with an opening at the top. The receiving cavity 21 and the mounting cavity 221 are separated from each other independently and do not affect each other, so as to prevent dust and water droplets from falling into the mounting cavity 221.

[0032] like Figures 2 to 5 As shown, the push assembly 33 can pass through the top of the box body 20, and the driving motor 31 drives the push assembly 33 to rise upward through the connecting assembly 32, so that the push assembly 33 passes through the top of the box body 20 and pushes the device to be charged 01 out of the accommodating cavity 21. For example, even after the wireless headset is loaded into the accommodating cavity 21, the head of the wireless headset (the larger end) will still be exposed, and the push assembly 33 passes through the top of the box body 20 and pushes the head of the wireless headset upward, thereby pushing the wireless headset out of the accommodating cavity 21. Other electronic devices are similar, and no further examples are given here.

[0033] like Figures 1 to 5 As shown, the top of the box body 20 is provided with a groove 231 for the charging device 01 to be inserted. After the charging device 01 is inserted into the groove 231, the placement stability of the charging device 01 can be enhanced. The push assembly 33 can pass through and exit the groove 231. The push assembly 33 has a first position (such as Figure 4 ) and a second position extending upwardly from the groove 231 (as shown Figure 3 As shown). The driving motor 31 drives the pushing assembly 33 to switch between the first position and the second position through the connecting assembly 32. In the process of switching from the first position to the second position, the driving motor 31 drives the pushing assembly 33 through the connecting assembly 32 to push up the device to be charged, so as to push the device to be charged out of the accommodating cavity 21.

[0034] Preferably, the pushing assembly 33 has a magnetic structure (not shown) for magnetically adsorbing the device to be charged. By using the magnetic structure to adsorb the device to be charged, the action process of ejecting the device to be charged out of the accommodating cavity 21 can be more stable and reduce shaking. In the prior art, the magnetic structure is generally provided on the box body 20, and the adsorption of the device to be charged is relatively large, and a large lifting force is required to eject the device to be charged. In contrast, the present invention arranges the magnetic structure on the pushing assembly 33, which avoids the above-mentioned problem. The driving motor 31 only needs to output a relatively small motor torque to eject the device to be charged, and the ejection speed is also guaranteed.

[0035] Furthermore, if Figure 6 , Figure 7 and Figure 8As shown, the push assembly 33 includes a push head 331 and a mounting seat 332. The mounting seat 332 is connected to the connecting assembly 32, the push head 331 is installed on the top of the mounting seat 332, the push head 331 is installed on the top of the mounting seat 332, the push head 331 can pass through and push out the groove 231, and a magnetic structure is provided inside the push head 331. The push head 331 pushes the charging device 01. Preferably, the push head 331 can be configured as a plastic structure, a metal structure, or a ceramic structure, and is filled with magnets inside, so that the wireless headset can be magnetically adsorbed. Of course, the push head 331 can also be configured as a magnet as a whole, and the wireless headset can be magnetically adsorbed by the magnetic force generated by itself. Since the bottom side of the head of the wireless headset is generally inclined, in order to better fit with the bottom side of the head of the wireless headset, so as to more stably push out the wireless headset, the top of the push head 331 is set as an inclined structure, or the top of the push head 331 is set as a curved structure inclined to one side.

[0036] like Figures 5 to 8 As shown, the push assembly 33 also includes a mounting rod 333, a spring 334 and a sleeve 335. The mounting rod 333 is vertically mounted on the mounting seat 332, the sleeve 335 is slidably mounted on the mounting rod 333, the spring 334 is sleeved on the mounting rod 333, the push head 331 and the sleeve 335 are respectively located on the upper and lower sides of the spring 334, and the spring 334 always has a tendency to drive the sleeve 335 away from the push head 331. The output end of the connecting assembly 32 is slidably mounted on the mounting rod 333, and the output end of the connecting assembly 32 is against the sleeve 335 and is arranged below the sleeve 335. The spring 334 plays a buffering role, making the process of ejecting the device to be charged 01 smoother and reducing the interference of factors such as vibration and shaking that occur during the process. Moreover, after the push head 331 moves into place, the output end of the connecting assembly 32 can also compress the spring 334 to a certain extent, so that it slides along the mounting rod 333 to eliminate the influence of the stroke error.

[0037] Preferably, when the push assembly 33 moves to the second position, the mounting seat 332 pushes against the bottom surface of the cover plate 23, or is close to the bottom surface of the cover plate 23, but not limited thereto, to limit the further extension of the push head 331. In the embodiment provided by the present invention, the mounting seat 332 is generally a cylindrical structure with a partially open side, but not limited thereto, and the mounting rod 333, the spring 334 and the sliding sleeve 335 are arranged in a cavity surrounded by the cylindrical structure.

[0038] like Figures 4 to 8As shown, the driving device 30 of the present invention also includes a structural seat 34 and a circuit board 35. The structural seat 34 is installed on the top of the circuit board 35, and the driving motor 31 is electrically connected to the circuit board 35 through FPC36. Preferably, the circuit board 35 has a connector, which is exposed from the box body 20. By connecting the power through the connector, the charging device 01 can be charged, and other batteries in the box body 20 can be charged. The connecting component 32 and the driving motor 31 are respectively installed on the structural seat 34. The structural seat 34 adopts a plastic structure, but is not limited to this. The connecting component 32 includes a screw rod 321 and a nut 322 that cooperates with the screw rod 321 for transmission. One side of the nut 322 extends a connecting structure that is slidably installed on the mounting rod 333. The nut 322 drives the push assembly 33 to move up and down along the up and down movement of the screw rod 321.

[0039] The control logic of the charging box 100 of the present invention is different from that of the prior art. The charging box 100 of the present invention includes two sets of independently controllable driving devices 30 (such as Figure 5 As shown in FIG. 2 , that is, the two sets of driving devices 30 may not move synchronously. The two sets of driving devices 30 are used to push the first device to be charged and the second device to be charged out of their respective accommodating cavities 21. In the embodiment provided by the present invention, two sets of driving devices 30 may be used to push out a pair of wireless headphones.

[0040] Specifically, the two groups of driving devices 30 include a first driving device and a second driving device, and the first driving device and the second driving device are arranged on both sides along the length direction of the charging box 100. The charging box 100 also includes a first sensor (not shown in the figure) for sensing whether the box cover 10 is in an open state or a closed state. When the first sensor senses that the box cover 10 is in an open state, the first driving device is linked to push out the first device to be charged and the second driving device is linked to push out the second device to be charged. When the first sensor senses that the box cover 10 is in a closed state, the first driving device is reset and the second driving device is reset. Even if only a single wireless headset is taken out, after closing the box cover 10, since the first sensor senses that the box cover 10 is in a closed state, the first driving device is reset and the second driving device is reset, the wireless headset drops at this time to avoid the wireless headset being stuck when the cover is closed.

[0041] It should also be noted that the box cover 10 is not in the closed state only when it is completely closed. As long as the box cover 10 is rotated within a certain angle range, it is in the closed state. On the contrary, the box cover 10 is in the open state outside the above angle range.

[0042] Furthermore, the charging box 100 also includes a second sensor for sensing whether the first device to be charged is taken out and a third sensor for sensing whether the second device to be charged is taken out. The second sensor resets the first drive device after sensing that the first device to be charged is taken out, and the third sensor resets the second drive device after sensing that the second device to be charged is taken out, thereby realizing the automatic descent of the first drive device and the second drive device. Preferably, the first sensor, the second sensor, and the third sensor can use Hall sensors, but are not limited thereto.

[0043] Figure 1 , Figure 5 , Figure 6 and Figure 8 In the figure, the direction indicated by arrow X is from left to right, the direction indicated by arrow Y is from front to back, and the direction indicated by arrow Z is from bottom to top.

[0044] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
