Test bracket for wireless charging device

Abstract

The invention discloses a test bracket for a wireless charging device. The test bracket includes a vertical motion mechanism which is used for mounting a receiving coil and driving the receiving coilto perform vertical motion, a horizontal motion mechanism which is used for mounting a transmitting coil and driving the transmitting coil to perform horizontal motion, and a supporting mechanism which is used for mounting the vertical motion mechanism and the horizontal motion mechanism. When testing is performed, a distance between the receiving coil and the transmitting coil can be changed by operating the vertical motion mechanism; the relative offset of the receiving coil and the transmitting coil can be changed by operating the horizontal motion mechanism; and at the same time, under thejoint action of the vertical motion mechanism and the horizontal motion mechanism, the test of the charging coil of a wireless charging pile device can be successfully completed; and since manual movement operation of the receiving coil and the transmitting coil is abandoned, instead, the movement operation of the receiving coil and the transmitting coil is realized through the mechanical movement of the vertical motion mechanism and the horizontal motion mechanism, the motion adjustment of the receiving coil and the transmitting coil has greater precision and accuracy, and at the same time,test accuracy and the reliability of test results are improved.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a test stand for a wireless charging device. Background technique [0002] With the development of power electronics technology in China, more and more electronic devices have been widely used. [0003] In the field of automobile manufacturing industry, the research and development of new energy vehicles has achieved results, and new energy vehicles such as pure electric vehicles and hybrid vehicles have appeared. Taking an electric vehicle as an example, an electric vehicle refers to a vehicle driven by a vehicle-mounted power supply and driven by a motor. It is equivalent to the engine of an internal combustion engine vehicle, and its importance is self-evident. The capacity of the battery is limited, and when the power is reduced to a certain level, it needs to be charged in time. [0004] At present, wireless charging technology is widely used in electric vehicle...

Problems solved by technology

[0005] In the prior art, the charging coil test of the traditional wireless charging pile device, during the test, the adjustment of the relative offset between the transmitting coil and the receiving coil, the adjustment of the distance between the two coils, the overall displacement of the two coils, etc. The change of the relative positional relationship is done manually. Since the transmitting coil and the receiving coil occupy a large area and are heavy, the operation is complicated and cumbersome, and the adjustment accuracy is difficult to guarantee. The reference value of the test results is not high.
