[0026] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0027] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0029] The embodiment of the utility model provides a docking station with a wireless charging module, such as Figure 1-5 As shown, it includes a bottom shell 100, a circuit board 200, a cover plate 300, a wireless charging coil 400 and a top plate 500. The bottom shell 100 can be a box-type structure, which is provided with a receiving groove, and the receiving groove forms an opening on the top surface of the bottom shell 100. The circuit board 200 is fixed in the bottom shell 100, and specifically, can be fixed in the receiving groove of the bottom shell 100. The cover plate 300 is fixed on the top of the bottom shell 100 and is located above the circuit board 200. The cover plate 300 can cover the opening on the top surface of the bottom shell 100 to provide dust protection for the circuit board 200.

[0030] The wireless charging coil 400 is fixed on the top surface of the cover plate 300, and the top plate 500 is arranged above the cover plate 300 and covers the wireless charging coil 400, so as to prevent the wireless charging coil 400 from being exposed to the outside, and to isolate and protect the wireless charging coil 400. In order to better play the role of isolation and protection, the top plate 500 can also cover the entire cover plate 300. The electronic device to be charged is used to be placed on the top plate 500, so as to wirelessly charge the electronic device through the wireless charging coil 400. The top plate 500 can be fixedly connected to the cover plate 300, and can also be fixedly connected to the bottom shell 100.

[0031] The wireless charging coil 400 needs to be powered to work. It is connected to the circuit board 200 through a wire, and the wire transmits electrical energy. The wireless charging coil 400 is wound with a core wire, and the wire can be connected to the core wire as a whole, that is, the wire is an extension of the core wire, or the wire can be fixedly connected to the connection end reserved for the core wire. The cover plate 300 is provided with a through wiring hole 310. The wire connected to the wireless charging coil 400 passes through the wiring hole 310 and is then connected to the circuit board 200 under the cover plate 300. This facilitates the routing of the wire to ensure the wireless charging function of the docking station.

[0032] In this embodiment, a plurality of data interfaces 210 are fixed on the circuit board 200, and a plurality of slots 110 adapted to the data interfaces 210 are provided on the surface of the bottom shell 100. The data interfaces 210 are arranged in the slots 110 so that an external connector can be plugged into the data interfaces 210, thereby realizing the basic interface expansion function of the expansion dock.

[0033] In some embodiments, a pad 600 is fixed to the top surface of the cover plate 300, and the wireless charging coil 400 is fixed on the pad 600. The pad 600 can provide support and protection for the wireless charging coil 400 from the bottom to avoid damage to the wireless charging coil 400. The pad 600 can be fixed to the top surface of the cover plate 300 in more ways.

[0034] In this embodiment, the pad 600 can be fixed to the top surface of the cover plate 300 by glue, tape or other fixing methods, and the wireless charging coil 400 can be fixed to the top surface of the pad 600 by glue, tape or other fixing methods that will not damage the wireless charging coil 400.

[0035] Furthermore, a notch 610 is provided at the outer edge of the pad 600, and the wire passes through the notch 610. The notch 610 can avoid the wire so that the wire does not extend out from between the wireless charging coil 400 and the pad 600. The wireless charging coil 400 can be fixed on the pad 600 more flatly to avoid affecting the performance of the wireless charging coil 400.

[0036] Furthermore, the top surface of the cover plate 300 is provided with a groove 320, and the pad 600 and the wireless charging coil 400 are both located in the groove 320. The groove 320 can position the pad 600, so that the pad 600 is not easy to move on the top surface of the cover plate 300, and the pad 600 can be more stably fixed on the top surface of the cover plate 300. At the same time, the pad 600 and the wireless charging coil 400 do not protrude from the cover plate 300, and the top surface of the cover plate 300 can be kept flat, which is convenient for the installation of the top plate 500.

[0037] Furthermore, the top surface of the cover plate 300 is also provided with a wiring groove 330 connecting the groove 320 and the wiring hole 310. The wire connected to the wireless charging coil 400 is first routed along the wiring groove 330 and then passes through the wiring hole 310, so that the position of the wire is limited by the wiring groove 330, so that the wire will not be arbitrarily offset, thereby ensuring the stable connection between the wire and the wireless charging coil 400 and the circuit board 200.

[0038] In some embodiments, the top plate 500 is tightly fixed on the cover plate 300, and can be fixed on the cover plate 300 by gluing to reduce the distance between the wireless charging coil 400 and the top surface of the top plate 500, thereby improving the power of wireless charging.

[0039] In some embodiments, the bottom surface of the cover plate 300 is provided with a connection column 340 extending downward, and the circuit board 200 is fixedly connected to the connection column 340. This allows the position of the circuit board 200 to remain stable, and at the same time, since the connection column 340 extends downward, the circuit board 200 can be spaced a certain distance from the cover plate 300 to prevent the components on the circuit board 200 from being squeezed by the cover plate 300. Specifically, the circuit board 200 can be fixed on the end surface of the lower end of the connection column 340, and screws can be used to fix the circuit board 200 on the connection column 340.

[0040] In some embodiments, a plurality of notches 220 are provided at the outer edge of the circuit board 200, and a plurality of positioning blocks 120 corresponding to the notches 220 are fixed in the bottom shell 100. The positioning blocks 120 are inserted into the notches 220 and all abut against the circuit board 200. The circuit board 200 is further positioned by the positioning blocks 120, so that the circuit board 200 is not easily displaced.

[0041] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
