Detailed Description

The present utility model will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.

Referring to fig. 1-4, example 1: the utility model discloses a switching structure of a wireless mobile phone charging support for improving charging rate, which is mainly used for adapting a mobile phone which does not have a wireless charging function to be used as a wired charging, and comprises a magnetic switching groove 1, wherein the magnetic switching groove 1 is arranged on a wireless mobile phone charging base 2 and is electrically connected with a chip main board of the wireless mobile phone charging, the chip main board is connected with a circuit board of the wireless mobile phone charging, the circuit board is connected with a power supply, at least seven charging contacts 3 are arranged in the magnetic switching groove 1, the switching structure also comprises a magnetic charging head 4, the magnetic charging head 4 comprises a magnetic charging end 41 and a joint end 42, the magnetic charging end 41 is just nested with the magnetic switching groove 1 and is mutually magnetically connected, the joint end 42 is just inserted into a charging interface of the mobile phone, the adapted joint end 42 comprises a model MicroUSB, typeC or a Lightning, and the like, and a charging ring 421 matched with the charging contacts 3 is arranged on the magnetic charging end 41.

Referring to fig. 3 and 4, specifically, the seven charging contacts 3 are a first contact 310, a second contact 320, a third contact 330, a fourth contact 340, a fifth contact 350, a sixth contact 360 and a seventh contact 370, which are preferably arranged side by side, wherein the first contact 310 and the seventh contact 370 are negative terminals, the second contact 320 and the sixth contact 360 are positive terminals, the third contact 330 and the fifth contact 350 are d+ signal transmission terminals, the fourth contact 340 is D-signal transmission terminals, the charging ring 421 is a first ring 410, a second ring 420, a third ring 430 and a fourth ring 440 from outside to inside, the first ring 410 is in contact with the first contact 310 and the seventh contact 370 of the charging contact 3, the second ring 420 is in contact with the second contact 320 and the sixth contact 360 of the charging contact 3, the third ring 430 is in contact with the third contact 330 and the fifth contact 350 of the charging contact 3, the fourth ring 440 is in contact with the fourth contact 440 of the charging contact 3, the respective magnetic attraction ring 421 is also provided with a magnetic attraction slot 450, and the magnetic attraction slot 450 is provided between the respective magnetic attraction ring and the magnetic attraction ring 1.
