Description

Technical Field

[0002] With the rapid development of science and technology, contact-based power transmission is increasingly unable to meet the growing needs of modern society. As a convenient way to transmit power, wireless charging technology has gradually become the mainstream to replace traditional wired charging methods. Wireless chargers use the principle of electromagnetic induction for charging, and their working principle is similar to that of a transformer. A wireless charging system usually consists of a transmitter and a receiver. The transmitter supplies power to the coil through a power source, generating an electromagnetic signal under the action of electricity; the coil at the receiving end receives the electromagnetic signal and converts it into current, thereby realizing energy transmission and charging of the device.

[0003] The core advantage of wireless charging technology is that it can transmit electrical energy without physical contact, eliminating the reliance on cables in traditional charging methods. Through electromagnetic wave propagation, electrical energy can be transmitted in the air and effectively used by the receiving device. This technology not only improves user convenience, but also greatly improves the safety and life of electrical equipment, because the use of wires is greatly reduced, avoiding problems such as cable aging and breakage.

The vertical portion is located in the installation gap between the upper bracket of the side box and the lower bracket of the side box. A rack meshing with a second driving gear 92 driven by a second electric mechanism is provided on the side surface of the vertical portion. Thus, the second electric mechanism drives the rack rod 81 to move up and down by driving the second driving gear 92 to rotate forward and backward. The two connecting rods 82 are connected to both sides of the hook portion at the bottom of the rack rod 81. One end of the connecting rod 82 is rotatably connected to the hook portion, and the other end is rotatably connected to its corresponding side wireless charging assembly 72. Moreover, a connecting seat for rotational connection extends downward and inwardly from the bottom of the side wireless charging assembly 72, that is, the other end of the connecting rod 82 is rotatably connected to the connecting seat.

The rotating part 31 is in a "Ji" shape, and both sides are connecting edges that are connected to the connecting columns with threaded holes provided inside the lower shell 21 by screws. The supporting part 32 is installed below the rotating part 31, and the rotating part 31 can rotate relative to the supporting part 32 through a supporting pin 33 passing through the upper part of the rotating part 31 and the supporting part 32; the upper shell 22 is in a frustum shape, and the bottom edge is connected to the top edge of the lower shell 21 to form an installation cavity. The top surface is flat, and a plurality of ventilation holes are provided on the top surface. Specifically, a plurality of connecting columns with threaded holes extending downward from the inner side of the top surface are provided inside the upper shell 22, and the upper shell 22 and the lower shell 21 are completely fixedly closed by screwing the upper shell 22 from the top surface through these connecting columns to the connecting columns with threaded holes provided inside the lower shell 21 that are opposite.
