Description

Technical Field

[0001] The utility model belongs to the technical field of wireless charging, and relates to a desktop wireless charger. Background Art

[0002] At present, for multi-functional wireless chargers, to solve the problem that the charger can also be used as a desktop stand, some products use a fixed-shaped stand to solve the vertical charger. For example, the product with the application number CN202311482826.1 has the disadvantages of huge volume, occupying a large space, and being easily damaged during logistics. Some products use a hinged swing to stand up the charging base. For example, the products with the application numbers CN202223022265.0 and CN202121547491.3 divide the flat type into two parts, and the two parts are connected together by hinges. One part is used as the base and the other part is used as the stand. The mobile wireless charging component swings relative to the base part along the hinge. The holding force after the above stand is erected is achieved through the friction of the folding hinge or the technology of supporting by a strut. There are disadvantages that after long-term use, the friction of the folding hinge decreases and the stand cannot be well maintained in the erected state, or it is inconvenient to use the strut. The latest technology, such as the multi-functional wireless charger with the application number 202420415366.4, is provided with a rotating head and openings are respectively arranged at different heights on its left and right sides. The openings are respectively provided with a first and a second ejection mechanism. The earphone box is placed on the first ejection mechanism, and the second ejection mechanism is used for charging the watch. The rotating head uses a motor for rotation, and when placing external products on the ejection mechanism, the center of gravity is relatively high. The ejection structure is arranged on the left and right sides. When charging, if one of the left and right sides is not placed, it will cause the problem of unstable center of gravity. It does not make good use of the internal space of the shell, and has the disadvantages of insufficient space utilization, high cost, and unstable placement during charging. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model aims to provide a small-sized wireless charger that can charge multiple products simultaneously and can also be used as a stand.

A mobile phone wireless charging device is arranged at the top of the shell. By reasonably using the characteristics of external products, it is cleverly set to be placed in layers. From top to bottom, it is for mobile phone, watch, and earphone charging.
