First embodiment

The first embodiment is a wireless charging module 100, and the specific structure thereof is shown in fig. 1 to 4.

As shown in fig. 1, the wireless charging module 100 includes a square housing 10. In other embodiments, the housing may be formed in other shapes, such as a circle, a regular polygon, a special shape, etc. The housing 10 includes a front cover 11 and a bottom cover 12 fixedly coupled to each other. The components of the wireless charging module 100 are disposed in the space between the front cover 11 and the bottom cover 12. In the first embodiment, the front cover 11 and the bottom cover 12 are detachably and fixedly connected. The housing 10 is provided with an external structure for fixing the wireless charging module 100 to an external object. In fig. 1, the circumscribed structure includes four evenly distributed perforations 13. The perforation 13 itself penetrates the front cover 11 and the bottom cover 12. The through hole 13 may penetrate a bolt and fix the wireless charging module 100 to an external object by the bolt. Still alternatively, the through hole 13 may penetrate a rope and bind the wireless charging module 100 to an external object through the rope.

As shown in fig. 2, a transmitting coil 21, a circuit board 22, and a heat dissipating plate 23 are sequentially provided from top to bottom in the space between the front cover 11 and the bottom cover 12. The circuit board 22 is provided with a power interface 24, and the power interface 24 is used for connecting an external power source to provide power for the wireless charging module 100. The circuit board 22 electrically connects the power interface 24 and the transmitting coil 21, respectively. The transmitting coil 21 is used for transmitting electromagnetic waves, and receiving the electromagnetic waves by a terminal to be charged or a wireless charging receiving patch of the terminal, so as to charge the terminal. In this embodiment, there are two power interfaces 24, which are a USB type-C socket 241 and a Micro-USB socket 242. The USBType-C socket 241 may be replaced by a USB-A, Mini-USB, Micro-USB or Lightning type socket. The Micro-USB socket 242 may be replaced with a USB-A, Mini-USB, USBType-C or Lightning type socket. The two power interfaces 24 of the first embodiment are arranged side by side at the same level and at a minimum distance of no more than 3mm from each other. In other embodiments, the two power interfaces may be disposed in parallel on the same vertical line, and the minimum distance between the two power interfaces does not exceed 2 mm.

As shown in fig. 2, the circumscribed structure further includes a magnet piece 27 built therein. The magnet piece 27 is fixed to the inner surface of the bottom cover 12. If a ferromagnetic metal piece/block is correspondingly disposed on the external object, the magnet piece 27 may be used to fix the wireless charging module 100 to the external object by magnetic attraction.

The heat radiating plate 23 in fig. 2 may be made of a stainless iron sheet or a stainless steel sheet. The disassembled structure in fig. 2 is assembled, and the heat dissipation plate 23 and the circuit board 22 are parallel to each other and attached to each other. One of the functions of the heat dissipation plate 23 is to conduct heat generated from the circuit board 22. The second function of the heat dissipation plate 23 is to increase the overall weight, improve the holding hand feeling, and improve the use experience after the wireless charging module 100 becomes smaller, lighter, and the holding hand feeling deteriorates. In addition, as shown in fig. 2, 4 positioning pillars 122 (two of which are hidden) are disposed on the bottom surface of the bottom cover 12. The positioning posts 122 sequentially penetrate through the heat dissipation plate 23 and the circuit board 22, so that the positioning posts 122 are used for fixing the positions of the circuit board 22 and the heat dissipation plate 23 in the bottom cover 12. The bottom surface of the bottom cover 12 is provided with mutually perpendicular plane protrusions 123 at the connection positions with the positioning columns 122, one function of the protrusions 123 is to enhance the strength of the positioning columns 122, and the other function is to separate the heat dissipation plate 23 from the bottom surface of the bottom cover 12, so as to avoid the uneven phenomenon caused by the fact that small burrs on the heat dissipation plate 23 abut against the bottom surface of the bottom cover 12.

As shown in fig. 2, the bottom cover 12 has four fastening locations 121, and the front cover 11 is fastened to the fastening locations 121 on the bottom cover 12, so that the front cover 11 and the bottom cover 12 can be fixedly connected to each other. In addition, the front cover 11 and the bottom cover 12 are fixedly connected by 4 screws 26 to further strengthen the connection stability of the front cover 11 and the bottom cover 12. As shown in fig. 2, a magnet ring 25 is interposed between the front cover 11 and the bottom cover 12. The magnetic ring 25 is coaxial with the screw 26, and the screw 26 passes through the center of the magnetic ring 25. Through the structure, the extra position occupied by the magnetic ring 25 can be saved, and the volume of the wireless charging module 100 can be made smaller. 4 magnetic rings 25 in fig. 2 are used for pasting the wireless subsides of charging on waiting to charge the terminal through magnetic attraction fixed connection, or are used for pasting sheetmetal or magnetic sheet on waiting to charge the terminal through magnetic attraction fixed connection for the terminal of waiting to charge can easily aim at wireless transmitting coil 21 automatically, and convenient to use nature is better.

As shown in fig. 3, the front cover 11 is provided with four sleeves 111 for fixing the magnetic ring 25 (fig. 2). After assembly, the outer wall of the magnetic ring 25 is tightly attached to the inner wall of the sleeve 111, so that the magnetic ring 25 cannot be loosened.

As shown in fig. 3, a positioning rod 112 is provided at an intermediate position inside the front cover 11. The positioning rod 112 penetrates through the hole 211 (fig. 2) of the transmitting coil 21 to fix the position of the transmitting coil 21 relative to the front cover 11, so as to prevent the transmitting coil 21 from shifting in the horizontal plane to cause inaccurate alignment during wireless charging.

As shown in FIG. 3, the circumscribing structure further includes a threaded hole 28 disposed at a central location on the bottom surface of the bottom cover 12. The threaded holes 28 are used for screwing with screws provided on an external object to achieve mutual fixation. The screw holes 28 are provided in a cylinder 124 (fig. 2) in the middle of the bottom cover 12, and the cylinder 124 penetrates the circuit board 22 and the heat radiating plate 23. In other embodiments, as shown in FIG. 6, the circumscribing structure further comprises a threaded aperture 113 disposed at a central location on the top surface of the front cover 11. The screw holes 113 are used for screw-coupling with screws provided on an external object to achieve mutual fixation.
