[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1-2 , the utility model provides the embodiment:

[0020] The modification-free wireless charging device for electric bicycles comprises an upper shell 1 and a lower shell 2. The bottom of the upper shell 1 is bolted and fixed to the lower shell 2 by bolts, and the bottom of the lower shell 2 is bolted and fixed to the transmitting integrated shell 3. A shielding chamber 7 is provided inside the upper shell 1. The inner wall surface of the shielding chamber 7 is equipped with a mainboard 9 by bolts. A working indicator light 5 is installed on one side of the top surface of the upper shell 1. The working indicator light 5 is electrically connected to the mainboard 9 by line matching. The mainboard 9 is electrically connected to a DC output line 13 by line matching, and the output end of the DC output line 13 runs through the surface of the upper shell 1. The surface of the upper shell 1 is integrally formed with an array heat dissipation structure, and the upper shell 1 is an integrated structure made of aluminum alloy material. The heat conduction requirements of the mainboard 9 are ensured. At the same time, a double shielding design (partial shielding plate of the magnetic core 8 + shielding chamber 7) is adopted to prevent magnetic field interference, ensure the normal operation of the mainboard 9 and the mainboard antenna 11, and enhance the waterproof and impact resistance of the mainboard through the glue filling process to adapt to complex outdoor environments.

[0021] The bottom of the mainboard 9 is bolted with a shielding bottom plate 10, the interior of the lower shell 2 is equipped with a magnetic core 8, the surface of the magnetic core 8 is wound with an induction coil 6, and the surface of the mainboard 9 is equipped with a mainboard antenna 11, which is electrically connected to the mainboard 9 through line matching. The bottom surface of the lower shell 2 is integrally formed with an anti-slip groove 14, and the surface of the transmitting integrated shell 3 is provided with an anti-slip convex groove 15, which is plugged and fixed with the anti-slip groove 14 set on the lower shell 2. The anti-slip convex groove 15 is provided at the bottom of the lower shell 2, which cooperates with the anti-slip groove 14 of the transmitting integrated shell 3 to ensure that the charger is stable when fixed by magnetic attraction and will not be easily moved due to external factors.

[0022] The inside of the transmitting integrated shell 3 is embedded with a sheet magnetic material 4, and the inner wall of the lower shell 2 is uniformly filled with four magnets 12 in sequence. The transmitting integrated shell 3 is installed in an underground manner. During the specific assembly process, only the upper shell 1 and the lower shell 2 are exposed to the outside. The magnetic material 4 is at least eight pieces, and the lower shell 2 is equipped with four magnets. The charging position is accurately located through the magnetic attraction effect to ensure the energy transmission efficiency, thereby forming a wireless energy transmission system. In addition, the main board 9 is also equipped with a transmitting unit and a receiving unit. The transmitting unit converts the AC power from the mains into high-frequency electromagnetic energy. It consists of an efficient power conversion module, a high-frequency inverter and a group of coupling coils arranged in the transmitting disk. The transmitting disk adopts a separate design and is arranged in the control cabinet and the transmitting disk respectively to ensure stability under long-term work. The receiving unit is a portable receiving disk with a built-in receiving coupling coil, a rectifier filter circuit and an intelligent identification chip. When the receiving disk is placed above the transmitting disk, it can effectively capture the electromagnetic field and convert it into DC power, and directly connect to the battery interface of the electric bicycle to achieve instant charging.

[0023] The electromagnetic energy generated by the transmitting disk is converted into electrical energy in the induction coil 6 of the receiving disk, and then directly charges the battery of the electric bicycle through the DC output line 13, avoiding energy loss and safety hazards in the process of AC power conversion. The wireless receiving disk uses magnetic suction to support charging in multiple directions, ensuring that electric bicycles of different models and different interface positions can be conveniently charged wirelessly.
