Referring to fig. 1 and 3, the utility model discloses charger, including shell 1, be provided with PCBA board 2 and the first wireless charging coil 3 of being connected with this PCBA board 2 electricity, the wireless charging coil 4 of second, charging connector 5 in this shell 1. The first wireless charging coil 3 is arranged close to one inner surface of the shell 1 and used for wirelessly charging the mobile phone; the second wireless charging coil 4 is arranged close to one inner surface of the shell 1 and used for wirelessly charging the watch; the interface of the charging connector 5 is exposed outside the shell 1 and is electrically connected with the earphone charging seat to charge the earphone. Wherein, a pen container 6 is arranged at the outer side of the shell 1, and pens can be placed through the pen container 6.

It should be understood that, in the present embodiment, the PCBA board 2 is implemented by using the prior art, which can control the first wireless charging coil 3 and the second wireless charging coil 4 to perform wireless charging and can supply power to the punishon connector 5; the pen is placed through the pen container 6. The technology increases the function of the charger and meets the use requirements of users.

Referring to fig. 1 and 2, the housing 1 in this embodiment has an overall box-like structure including a base 16 and an upper cover 17. The base 16 and the upper cover 17 are fixedly connected into a whole during assembly, and a containing cavity is formed inside. PCBA board 2, first wireless charging coil 3, the wireless charging coil 4 of second, charging connector 5 are all accomodate in this holding intracavity. It will be appreciated that in this embodiment, the base 16 and the cover 17 are made of a plastic material, which can be removably connected by means of a screw or snap connection. For example, when a screw connection is adopted, the screw is screwed upwards at the bottom of the base 16 to realize the screw connection with the upper cover 17.

It should be noted that, first wireless charging coil 3 and second wireless charging coil 4 are hugged closely an internal surface setting of shell, have reduced this first wireless charging coil 3 and second wireless charging coil 4 and the distance that corresponds cell-phone and wrist-watch like this, can make things convenient for charging of cell-phone and wrist-watch.

In detail, referring to fig. 1, the housing 1 has a first upper surface 11, a portion of the charging connector 5 is exposed at the first upper surface 11, and the pen barrel 6 is disposed on the first upper surface 11. The second wireless charging coil 4 is tightly attached to the inner side of the first upper surface 11. Specifically, the first upper surface 11 is an upper surface of the upper cover 17. Thus, in use, the charging is triggered by placing the watch on the first upper face 11 of the case 1.

In some embodiments, as shown in fig. 1, a circular charging area 111 is disposed at the first upper surface 11, and the inner side of the charging area 111 is the second wireless charging coil 4. Placing the watch in this charging area 111 while charging triggers the PCBA board 2 to charge the watch. For the convenience of the manufacturing process of the housing 1, the plane of the charging area 111 is the same plane as the first upper surface 11. It is further noted that, in order to ensure that the watch does not easily move during the charging process, an anti-slip adhesive layer 112 is disposed on the charging area 111. When the watch is used, the watch is placed on the anti-slip glue layer 112, and friction force generated by the contact surface of the anti-slip glue layer 112 and the watch can ensure that the watch cannot be easily displaced. The anti-slip adhesive layer 112 is preferably a silicone pad.

It is known that, since the watchband is attached to both ends of the case of a wristwatch, there are projections extending like a bottom at both ends of the case. Referring to fig. 1 and 2, in order to avoid that the watch is supported away from the charging area 111 due to the protruding part, in the present technical solution, a concave groove ring 113 is provided around the circumference of the charging area 111, and when in use, the protruding parts at the two ends of the watch case of the watch will fall into the groove ring 113, thus ensuring that the lower surface of the watch is in close contact with the charging area 111 to ensure effective charging. Wherein it should be understood that the groove ring 113 is integrally formed with the upper cover 17. The cross-sectional shape of the groove ring 113 can be designed in various suitable shapes, for example, in the form of a semicircle.

Preferably, as shown in fig. 1 and 2, in order to reduce the lateral external dimension of the housing 1 as much as possible and facilitate wireless charging of the mobile phone, the first upper surface 11 has a protruding portion 12 protruding upward, a cavity for accommodating the first wireless charging coil 3 is formed in the protruding portion 12, and the protruding portion 12 has a second upper surface 13 for attaching to the mobile phone. The first wireless charging coil 3 is disposed at a position where it is attached to the inner surface of the second upper surface 13. The transverse size of the upper cover 17 can be reduced through the arrangement of the convex part 12, and the situation that too large area is occupied for realizing wireless charging of the mobile phone is not needed, and then the external dimension of the whole shell 1 is increased. Specifically, in the present embodiment, the protruding portion 12 has a substantially right-angled trapezoid shape, wherein the right-angled side is perpendicular to the first upper surface 11. Specifically, the second upper surface 13 is an inclined surface, and the inclination angle alpha of the inclined surface meets the condition that the angle alpha is more than or equal to 60 degrees and less than 90 degrees. The inclined plane is designed to ensure that the mobile phone can be placed better when the mobile phone is wirelessly charged, and the placing stability of the mobile phone is ensured. In order to ensure that the second upper surface 13 has a sufficient length without increasing the height dimension of the protruding portion 12, the second upper surface 13 extends from the upper end of the protruding portion 12 to below the upper surface of the upper cover 17.

Referring to fig. 2, in some other embodiments, in order to prevent the mobile phone from slipping off when the mobile phone is wirelessly charged, a card slot 14 for limiting the position of the mobile phone is formed at the bottom of the second upper surface 13. When in use, the card slot 14 can contact with the bottom of the mobile phone to limit the mobile phone from slipping. Wherein, the card slot 14 is enclosed by the second upper surface 13 and a blocking part 18 arranged on the upper cover 17. In order to accommodate different sizes of mobile phones, the left and right sides (i.e., the upper and lower sides shown in fig. 1) of the card slot 14 penetrate through the side surface of the upper cover 17.

Referring to fig. 2, in order to facilitate stable placement of the earphone charging socket during electrical connection, a card socket 15 for fixing the earphone charging socket is disposed around the charging connector 5. The front and rear sides (i.e., the left and right sides shown in fig. 2) of the card holder 15 are formed with constraints, and the left and right sides (i.e., the upper and lower sides shown in fig. 2) are in a penetrating state, so that the card holder can be adapted to the use of earphone charging seats with different widths. Specifically, the longitudinal section of the card holder 15 can be designed and matched according to the shapes of different types of earphone charging seats. Preferably, in the present embodiment, the longitudinal section of the holder 15 is U-shaped. Specifically, the clamping seat 15 may be integrally formed with the upper cover 17 or may be a split structure. When the split structure is adopted, the first upper surface 11 of the upper cover 17 can be fixedly connected with the screw.

In some embodiments, referring to fig. 2, the barrel 6 and the housing 1 are removably connected. This enables the replacement connection of the barrel 6 according to the use. Preferably, the barrel 6 is connected to the housing 1 by means of a screw connection. Specifically, the bottom of the pen container 6 is provided with an extension part (not shown in the figure) protruding outwards, and the extension part is provided with an external thread which is in threaded connection with a threaded hole arranged in the shell 1 to realize matching. In particular, the barrel 6 may be of various shapes, for example cylindrical.
