The detailed description in the detailed implementation manners should be understood as an explanatory description of the purpose of the present application and should not be regarded as an improper limitation of the present application.

[0031] The present application will be further described in detail below with reference to the drawings and specific embodiments. The descriptions such as "first" and "second" in the embodiments of the present application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0032] An embodiment of the present application provides a wireless charger. Please refer to Figures 1 to 8 , the wireless charger 100 includes a housing 1, a circuit board 2, a telescopic wire assembly 3 and a wireless charging assembly 4. The housing 1 forms a receiving cavity 1a. The circuit board 2 is disposed in the receiving cavity 1a, and the circuit board 2 is provided with a limiting bayonet 2a. The telescopic wire assembly 3 is disposed in the receiving cavity 1a. A part of the telescopic wire assembly 3 passes through the limiting bayonet 2a. A telescopic wire 3a is disposed in the telescopic wire assembly 3, and the telescopic wire 3a is electrically connected to the circuit board 2. The wireless charging assembly 4 is disposed in the receiving cavity 1a, and the wireless charging assembly 4 is electrically connected to the circuit board 2.

[0033] The wireless charger 100 provided in the embodiment of the present application has a housing cavity 1a formed in the housing 1, and the circuit board 2, the retractable wire assembly 3, and the wireless charging assembly 4 can all be arranged in the housing cavity 1a, so that they can be protected to a certain extent, so as to effectively reduce the damage caused to the circuit board 2, the retractable wire assembly 3, and the wireless charging assembly 4 by dust, moisture, and physical impact, thereby extending the service life of the circuit board 2, the retractable wire assembly 3, and the wireless charging assembly 4. By setting the retractable wire assembly 3, the retractable wire 3a therein can supply power to the wireless charging assembly 4 through the circuit board 2, and then charge the electronic device. When not in use, the retractable wire 3a can be automatically or manually retracted to reduce the space occupied by the retractable wire 3a, making it easy to carry, so as to effectively solve the problem of entanglement and storage of the charging wire and improve the neatness of the desktop. By providing a limiting slot 2a on the circuit board 2, part of the telescopic wire assembly 3 is inserted into the limiting slot 2a. In this way, on the one hand, the telescopic wire assembly 3 can be limited, the shaking of the telescopic wire assembly 3 during use can be reduced, and its working stability can be improved; on the other hand, by partially inserting the telescopic wire assembly 3 into the limiting slot 2a, the telescopic wire assembly 3 can be partially overlapped with the circuit board 2 along the opening direction of the limiting slot 2a.

In this way, on the one hand, the opening size of the limiting clamp 2a on the circuit board 2 can be reduced, so that more components can be arranged on the circuit board 2 to improve the performance of the wireless charging assembly 4; on the other hand, by abutting the cavity wall of the accommodating cavity 1a against the portion of the telescopic wire assembly 3 passing through the avoidance opening 2b, the limiting of the telescopic wire assembly 3 can be strengthened; on another hand, by providing the avoidance opening 2b, when the circuit board 2 and the telescopic wire assembly 3 are installed, the alignment accuracy of the limiting clamp 2a and the telescopic wire assembly 3 is reduced, thereby reducing the difficulty of installation.
