Embodiment 1

[0020] The protection device in this embodiment is located on the periphery of the transmitting coil of the wireless charging pile, encloses the transmitting coil of the wireless charging pile inside the protection device, and is provided with a foreign object detection device above the transmitting coil of the wireless charging pile. The bottom of the protection device is a base 5 fixed on the ground, and the top is provided with a lifting bracket. The protection device includes a control circuit, a lifting system, and a contact sensing module 2 above the lifting system, wherein the contact sensing module 2 is located on the upper side of the lifting bracket.

[0021] The control circuit includes a main control module, a communication module for information interaction with the main control module and the wireless charging pile, and a lifting circuit is provided in the lifting system, the output end of the main control module is connected to the input end of the lifting circuit...

Embodiment 2

[0035] The main structure in this implementation is similar to Embodiment 1, the difference is that the control circuit also includes an alarm module connected to the output terminal of the main control module, which is used to give an alarm when a foreign object is detected, and remind relevant personnel to process.

[0036] And in this embodiment, a stretchable protective layer 6 surrounding the contact sensor module 2 and the base 5 is provided on the outside of the protective device, the upper end of which is connected to the upper end of the lifting mechanism, and the lower end is connected to the base 5 . The outer stretchable protection layer is made of plastic material, which can protect the internal structure of the protection device without affecting the wireless power transmission.

[0037]In this embodiment, a lifting plate is arranged on the top of the X-shaped telescopic bracket 4, and the endpoints A and B are located on the lower surface of the lifting plate, a...

Abstract

The invention belongs to the field of wireless power supply, and especially relates to a protective device for a wireless power transmission coupling zone. The protective device comprises a control circuit, an elevating system connected with the control circuit and a contact sensing module positioned above the elevating system, wherein the elevating system comprises an elevating circuit, a transmission device, and an elevating mechanism connecting the contact sensing module and the transmission device, and the transmission device is connected with the elevating circuit. The protective device is fully automatic and requires no manual operation. The protective device saves manpower and does not affect wireless power transmission efficiency.

Description

technical field [0001] The invention belongs to the field of wireless power supply, in particular to a protection device for a wireless power transmission coupling area. Background technique [0002] Wireless charging, also known as inductive charging, non-contact inductive charging, uses near-field induction, that is, inductive coupling, to transmit energy from a power supply device (charger) to a device that uses electricity, and the device uses the received energy to The battery is charged and simultaneously used for its own operation. Since energy is transmitted between the charger and the power-consuming device through inductive coupling, there is no need for wires to connect the two, so that both the charger and the power-consuming device can have no exposed conductive contacts. When performing wireless power transmission, it is mainly based on the uniform high-frequency alternating magnetic field generated between the transmitting coil and the receiving coil. The tr...
