The invention provides a charging box.

Referring to fig. 1, fig. 2, fig. 3 and fig. 4, in an embodiment of the present invention, the charging box includes a box body 10, a box cover 30 and a conductive structure 50; wherein, a circuit board 11 is arranged in the box body 10; the box cover 30 is movably connected with the box body 10 and can cover or open the box body 10; the conductive structure 50 can be driven by the box cover 30, and when the box cover 30 covers the box body 10, the box cover 30 drives the conductive structure 50 to abut against the conducting circuit board 11; when the box cover 30 opens the box body 10, the conductive structure 50 is separated from the disconnection circuit board 11.

In an embodiment of the present invention, the case 10 may be mainly used for accommodating various components of the wireless headset and the charging case themselves, such as: the charging box comprises a circuit board 11 and parts such as a storage battery 13 and the like which are electrically connected with the circuit board 11, so that the parts of the charging box are assembled into a whole to facilitate the carrying and the use of the charging box. The cover 30 is mainly used to cover the case body 10 to cover the wireless headset disposed on the case body 10 and reduce the possibility of damage to the wireless headset by external objects. Meanwhile, the box cover 30 can also be used for driving the conductive structure 50, so that when the box cover 30 covers the box body 10, the conductive structure 50 is in contact with the conducting circuit board 11, and the charging box is automatically started to charge the wireless earphone in the charging box; when the box cover 30 opens the box body 10, the conductive structure 50 is separated from the disconnection circuit board 11, so that the charging box is automatically closed to charge the wireless headset in the charging box. In order to facilitate the placement of the wireless headset, the box body 10 may be provided with a lower headset groove 12, the box cover 30 may be provided with an upper headset groove 31 at a position corresponding to the lower headset groove 12, the lower headset groove 12 and the upper headset groove 31 cooperate to form a headset accommodating cavity 15, and the wireless headset may be accommodated in the headset accommodating cavity 15. Moreover, carry out the holding to wireless headset through this earphone holding chamber 15, can increase the spacing butt area of the box of charging to wireless headset to can improve the spacing effect to wireless headset, so that wireless headset is stable arranges in the box of charging and charges (because the box of charging is prior art to wireless headset's the principle of charging, so do not describe in detail this charging process here). Of course, the present invention is not limited thereto, and in other embodiments, the wireless headset may be accommodated only through the lower headset slot 12 disposed on the box body 10. In order to improve the convenience of connecting the cover 30 and the case 10 and to prevent the cover 30 from being positioned at another position after being opened, in an embodiment of the present invention, one side of the cover 30 may be rotatably connected to the case 10, and the other opposite side and the case 10 may be detachably connected to the case 10. Wherein, a side edge of the box cover 30 can be connected with the box body 10 by a hinge, certainly, the box body 10 can also be provided with one of a rotating shaft and a shaft hole, the box cover 30 is provided with the other of the rotating shaft and the shaft hole, and the rotating matching is realized by the rotating shaft and the shaft hole. The other side of the box cover 30 and the box body 10 can be detachably connected through a snap connection or a magnetic attraction fixation. Of course, a torsion spring may be directly disposed at the rotation position of the box cover 30 and the box body 10, and the box cover 30 may be driven to cover the box body 10 by the torsion spring. At this time, if the box cover 30 needs to be opened, an external force acts on the box cover 30 to overcome the action force of the torsion spring and open the box cover 30. Of course, in other embodiments, the cover 30 may be slidably connected to the cover 30, and the cover 30 may be driven to slide relative to the case 10 to close or open the case 10; or, the box cover 30 is movably connected to the box body 10 only by magnetic attraction or snap connection. In addition, in order to facilitate the molding of the case body 10 and the case cover 30, the case body 10 and the case cover 30 may be formed in a substantially rectangular parallelepiped shape, so that the case body 10 and the case cover 30 have regular shapes and the molding complexity is reduced. Further, the lateral surface of the box body 10 and the lateral surface of the box cover 30 may be located on the same plane, so that the shape of the box body 10 and the box cover 30 is regular and the volume is relatively small. Of course, the present invention is not limited thereto, and in the embodiment, the box body 10 and the box cover 30 may be both substantially cylindrical. The circuit board 11 can be mainly used for controlling the storage battery 13 to start or close to charge the wireless headset in the charging box, so that the controllability of the charging box to the wireless headset in the charging process is improved. The conductive structure 50 can be mainly used for abutting against the conducting circuit board 11 to trigger the circuit board 11 to open and control the charging box to charge the wireless headset. Specifically, the circuit board 11 may be provided with two contacts, and when the conductive structure 50 is not abutted to the two contacts, the circuit on the circuit board 11 is in an open state, so that the storage battery 13 is turned off to charge the wireless headset located in the charging box. When the conductive structure 50 abuts against the two contacts, the circuit on the circuit board 11 is in a conducting state and the battery 13 is turned on to charge the wireless headset in the charging box.

When the charging box of the technical scheme of the invention is used for charging the wireless earphone, the box cover 30 is firstly opened and the wireless earphone is placed in the box body 10. Then, the box cover 30 is covered on the box body 10, and at the moment, the conductive structure 50 can be driven by the box cover 30 to be abutted and conducted on the circuit board 11 arranged on the box body 10, so that when the box cover 30 covers the box body 10, the circuit board 11 is automatically opened to control the charging box to charge the wireless earphone. And after the charging box charges the wireless earphone for a certain time, the conductive structure 50 can be separated from the disconnection circuit board 11 when the box cover 30 is opened, so that the circuit board 11 is automatically closed to control the charging box to stop charging the wireless earphone when the box cover 30 opens the box body 10.

In addition, the charging box in the scheme is connected or disconnected with the circuit board 11 through the abutting connection of the conductive structure 50, so that the circuit board 11 can be automatically opened or closed in the charging process of the earphone. Compared with the prior art in which the charging box realizes the automatic opening or closing of the circuit board 11 to the earphone in the charging process through the induction between the magnet and the hall element, the direct abutting connection of the conductive structure 50 to the circuit board 11 in the scheme is triggered mechanically, and the interference of various signals in the environment to the circuit board can be avoided. The circuit board 11 can be effectively conducted and triggered in time when the conductive structure 50 abuts against the conductive structure, so that the sensitivity and stability of triggering the circuit board 11 are improved. Meanwhile, the cost of the conductive structure 50 in the scheme is not high as that of the magnet and the Hall element, and the number of devices required to be arranged is reduced, so that the manufacturing cost of the charging box is reduced.

Referring to fig. 3 and 4, in an embodiment of the present invention, the conductive structure 50 includes an elastic member 51 and a conductive member 53, the elastic member 51 is connected to the box body 10, an end of the elastic member 51 away from the circuit board 11 is used for abutting against the box cover 30, and when the box cover 30 covers the box body 10, the elastic member is driven by the box cover 30 to deform in a direction facing the circuit board 11; the conductive member 53 is driven by the elastic member 51 to abut against the conductive circuit board 11 when the elastic member 51 is driven by the cover to deform.

It can be understood that the elastic member 51 has elasticity, so that it can be deformed in a direction facing the circuit board 11 when it is driven to abut against the box cover 30. Meanwhile, the cover 30 can indirectly drive the conductive member 53 through the elastic member 51 in the process of covering the case body 10, so that the conductive member 53 is abutted against the circuit board 11. When the box cover 30 is opened, the elastic member 51 is driven to restore by the deformation elastic force generated by the previous deformation of the elastic member 51, that is, the elastic member 51 moves in the direction away from the circuit board 11, and the conductive member 53 resets along with the disappearance of the abutting driving force, so that the conductive member 53 is separated from the circuit board 11. Therefore, the elastic member 51 is provided so that the conductive member 53 can be automatically restored when the cover 30 is opened, and a restoring structure for connecting the cover 30 and the conductive member 53 is not additionally provided, thereby simplifying the structure of the charging box and facilitating the molding manufacture of the charging box. Meanwhile, the elastic element 51 has a shielding effect on the conductive element 53, and can play a certain isolation and insulation effect on the conductive element 53, so that the possibility of electric shock caused by contact between a user and the conductive element 53 is reduced, and the safety of the charging box in the use process can be improved. Meanwhile, due to the arrangement of the elastic piece 51, the box cover 30 indirectly abuts against the conductive piece 53, the abutting abrasion of the box cover 30 and the conductive piece 53 can be reduced, and the service life of the charging box can be prolonged. The elastic member 51 may be made of silicone, rubber, or other plastic materials with certain elasticity. The conductive member 53 may be made of graphite carbon, copper or other metal material with conductive property. Of course, the present application is not limited thereto, and in other embodiments, the conductive member 53 may be inserted into the elastic member 51, an upper end of the conductive member 53 is used for contacting with the box cover 30, and a lower end is used for contacting with the circuit board 11. That is, when the cover 30 is fitted to the case body 10, the cover 30 directly abuts against the driving conductive member 53 and descends to abut against the conductive circuit board 11.

In an embodiment of the present invention, a receiving groove 511 is formed in a surface of the elastic element 51 facing the circuit board 11, and a portion of the elastic element 51 is received in the receiving groove 511.

It can be understood that the elastic member 51 covers at least a portion of the conductive member 53 by forming the receiving groove 511, so that the elastic member 51 and the space therebetween are more compactly distributed, thereby reducing the occupied space, and facilitating the reduction of the overall volume of the charging box for further convenience of carrying. Meanwhile, the protection of the insulation of the conductive member 53 is also improved by the cover of the conductive member 53 provided with the accommodation groove 511. When the conductive member 53 is connected to the elastic member 51, the contact area between the conductive member 53 and the elastic member 51 can be increased, thereby improving the connection stability between the conductive member 53 and the elastic member 51. The shape of the receiving groove 511 may be circular, square, oval or other shapes, and may be specifically set according to the shape of the conductive member 53.

Referring to fig. 3 and fig. 4, in an embodiment of the present invention, the conductive member 53 is connected to the bottom wall of the accommodating groove 511, and an end of the conductive member 53 away from the bottom wall of the accommodating groove 511 is used for abutting against and conducting the circuit board 11.

It can be understood that the conductive member 53 is directly fixed to the elastic member 51, so that the distribution of the conductive member and the elastic member is more compact, thereby being beneficial to reducing the occupied space. Meanwhile, due to the arrangement, when the elastic element 51 is abutted and driven by the box cover 30, the driving force of the box cover 30 can be effectively transmitted to the conductive element 53 in time, so that the conductive element 53 is driven by the elastic element 51. The conductive member 53 and the elastic member 51 may be fixed by gluing, or may be an integral structure.

Referring to fig. 5 and fig. 6, in an embodiment of the invention, the circuit board 11 is provided with a mounting seat 111 at a position corresponding to the accommodating groove 511, the conductive member 53 is movably disposed on the mounting seat 111, one end of the conductive member 53 away from the circuit board 11 extends into the accommodating groove 511, and one end facing the circuit board 11 is used for abutting against and conducting the circuit board 11.

It can be understood that the installation position of the conductive member 53 is given by the installation seat 111, and at this time, it is convenient to provide a corresponding installation structure on the installation seat 111 to perform stable limiting and fixing on the conductive member 53. Meanwhile, the installation structure arranged on the installation seat 111 does not cause excessive influence on the circuit board 11. That is, the installation of the conductive member 53 is facilitated, and the influence of the self-structure of the circuit board 11 is reduced. The combination of the mounting seat 111 and the conductive piece 53 can be formed as a Switch, which can conduct the circuit board 11 after being indirectly pressed by the box cover 30 through the elastic piece 51; when the cover 30 is opened and pressed against the circuit board 11, the circuit board can be disconnected. Since the specific operation principle of the Switch is the prior art, it will not be described in detail here. A certain distance may be provided between one end of the conductive member 53 away from the circuit board 11 and the bottom wall of the receiving groove 511, so that the conductive member 53 is indirectly driven to descend through the elastic member 51 only when the box cover 30 is covered to a certain degree, thereby reducing the possibility that the conductive member 53 is driven due to the elastic member 51 being touched by mistake. Of course, it is also possible that one end of the conductive member 53 away from the circuit board 11 directly abuts against the bottom wall of the receiving groove 511. In addition, it should be noted that the present application is not limited thereto, and in other embodiments, the mounting base 111 may also be a plastic housing, and the conductive member 53 is a metal conductive sheet that is disposed in the plastic housing and can be lifted or lowered, or a deformable metal elastic sheet that is disposed in the plastic housing.

Referring to fig. 5, in an embodiment of the present invention, a receiving cavity 15 is formed in the box body 10, the box body 10 is further provided with a mounting hole 17 communicating with the receiving cavity 15, and the mounting hole 17 is disposed facing the box cover 30; the circuit board 11 is arranged in the accommodating cavity 15, and the elastic piece 51 is arranged in the mounting hole 17.

It can be understood that the accommodating cavity 15 provides a mounting space for the circuit board 11, which makes the circuit board 11 mounted in the box 10 more compact. Meanwhile, the accommodating cavity 15 has an isolation protection effect on the circuit board 11, so that the possibility of damage to the circuit board 11 caused by external water vapor or dust and the like is reduced, and the service life of the circuit board 11 is prolonged. In this case, the storage battery 13 may also be disposed in the accommodating cavity 15 to enhance the sealing protection of the storage battery 13, and the conductive member 53 may be partially disposed in the accommodating cavity 15.

In an embodiment of the invention, a slot 513 is formed on an outer peripheral surface of the elastic element 51, and a portion of the box 10 is embedded in the slot 513 and abuts against a wall of the slot 513.

It can be understood that the elastic member 51 is clamped and fixed to the case 10 through the clamping groove 513, so that a connection structure or an additional connection structure does not need to be provided on the case 10 to connect the elastic member 51, thereby simplifying the fixing structure of the elastic member 51 and facilitating further reduction of the manufacturing cost of the charging case. Of course, the present application is not limited thereto, and in other embodiments, the elastic element 51 and the box 10 may be fixed by gluing, or may be in interference fit with the mounting hole 17. The clamping groove 513 can surround the elastic element 51 for a circle, so that the clamping limiting effect of the elastic element 51 and the box body 10 is improved, and the processing complexity of the clamping groove 513 can be simplified. Of course, the locking slot 513 may also be provided with multiple segments spaced apart along the circumference of the elastic member 51.

In an embodiment of the present invention, the surface of the box body 10 facing the box cover 30 is further concavely formed with a mounting groove 19, and the mounting hole 17 is provided in a groove bottom wall of the mounting groove 19.

It can be understood that the installation groove 19 is configured to accommodate the elastic member 51, so that the installation of the elastic member 51 and the conductive member 53 on the box 10 is more compact, thereby further reducing the space occupation.

Referring to fig. 5 and fig. 6, in an embodiment of the invention, the surface of the box cover 30 facing the box body 10 is provided with a contact column 33, the contact column 33 is disposed opposite to the mounting groove 19, and when the box cover 30 is covered on the box body 10, the contact column 33 contacts the elastic member 51 and drives the elastic member 51 to deform.

It can be understood that the abutting column 33 is protruded on the box cover 30 to abut against the elastic member 51, so that a notch which is not protruded out of the installation groove 19 can be formed at one end of the elastic member 51 close to the installation groove 19, and at this time, the elastic member 51 is relatively less embodied, which can further reduce the space occupation, and also reduce the raw materials required by the elastic member 51 during manufacturing, thereby reducing the manufacturing cost. Wherein, the area of the cross section of the convex column can be slightly smaller than the area of the mounting groove 19, and the shapes of the convex column and the mounting groove can be matched. Of course, when the contact post 33 is not provided on the box cover 30, one end of the elastic member 51 close to the mounting groove 19 may protrude from the notch of the mounting groove 19 so that the box cover 30 can contact the box body 10 when covering the box body.

Referring to fig. 7 and 8 in combination, in an embodiment of the invention, the conductive structure 50 includes a conductive element 55, and the conductive element 55 is defined to have two opposite ends; one end of the conduction member 55 is connected to the box cover 30, and the other end is used for abutting against the conduction circuit board 11 when the box cover 30 is covered on the box body 10.

It can be understood that the conducting element 55 is directly connected to the box cover 30, when the box cover 30 covers the box body 10, the conducting element 55 is directly driven to approach the abutting conducting circuit board 11, and when the box cover 30 is opened, the conducting element 55 is directly driven to be away from the disconnecting circuit board 11. The stability of the conducting piece 55 in driving can be improved, and when the box cover 30 is closed or opened, the conducting piece 55 can timely and effectively conduct or disconnect the circuit board 11. When the circuit board 11 is disposed in the accommodating cavity 15 of the box 10, the conducting member 55 can pass through the mounting hole 17 communicating with the accommodating cavity 15 to abut against the circuit board 11. In an embodiment of the present invention, the number of the through-conductors 55 is two, and the conductive structure 50 further includes a connecting member 57; connecting piece 57 is connected in lid 30, and two one ends that lead to piece 55 all connect in connecting piece 57 and be interval distribution, and the other end all is used for the butt when lid 30 covers box body 10 and leads to circuit board 11.

It can be understood that the conductive structure 50 is composed of two conducting pieces 55 and a connecting piece 57 connecting the two conducting pieces 55, so that the conductive structure 50 can respectively abut against two contacts on the circuit board 11 through two conducting electricity, and at this time, the volumes of the two conducting pieces 55 can be relatively smaller, thereby reducing the manufacturing cost of the conductive structure 50.
