[0023] In the first embodiment of the present invention, the main coupling core 32 is a U-shaped core, and the auxiliary coupling core 56 is a corresponding cuboid core. The specific implementation method is: a single primary cable 2 is laid according to the running path of the mobile device, and the primary cable 2 is placed in the primary cable sleeve 54 . The main coupling magnetic core 32 wound with the induction coil 30 is fixed in the main coupling magnetic core support 55 , and the auxiliary coupling magnetic core 56 is fixed in the auxiliary coupling magnetic core support 57 . On this basis, the main coupling magnetic core support 55 and the auxiliary coupling magnetic core support 57 are assembled, and the finally assembled closed contactless power-taking device and the primary side cable 2 undergo coupling electromagnetic induction. The main coupling magnetic core 32 , the auxiliary coupling magnetic core 56 , the main coupling magnetic core support 55 and the auxili...

Abstract

The invention relates to a non-contact power supply closed type power collector which belongs to the technical field of non-contact power supply. The non-contact power supply closed type power collector is composed of a main coupling magnetic core (32), an auxiliary coupling magnetic core (56), a main coupling magnetic core bracket (55) and an auxiliary coupling magnetic core bracket (57), wherein the main coupling magnetic core (32), auxiliary coupling magnetic core (56), main coupling magnetic core bracket (55) and auxiliary coupling magnetic core bracket (57) can move along with a mobile device. The non-contact power supply closed type power collector can effectively improve the defect of low electric power transmission efficiency of the power collector in the prior non-contact power supply technology, and enhances the electromagnetic coupling coefficients, thereby obviously enhancing the electric power transmission efficiency.

Description

technical field [0001] The invention relates to a non-contact power supply closed-type power-taking device, which belongs to the technical field of non-contact power supply. Background technique [0002] The non-contact power supply technology can be used to realize the non-contact transmission of electric energy. The core part of the electric energy transmission is the loosely coupled electromagnetic induction between the primary cable loaded with high-frequency sinusoidal alternating current and the open power take-off device. After the high-frequency electromagnetic coupling induction, the electric energy is obtained to supply power to the equipment. [0003] Existing patents on contactless power supply technology, such as Chinese patent 200410096738.9, US patent US007119311B2, US patent US20050133497A1, Japanese patent P2005-102378A, Japanese patent P2007-50799A, and Chinese patent 01816910.4, all of their power-taking devices are open structures. Both are loosely coupl...
