A new energy vehicle charging line recovery device based on capacitive sensing

Abstract

The invention relates to the technical field of new energy vehicles, and discloses a charging line recovery device for new energy vehicles based on capacitive sensing, which includes a casing, the outside of the casing is movably connected with a sensing component, and the inside of the casing is fixedly connected with a Motor one, the external movable connection of motor one is provided with a bevel gear, the external movable connection of the bevel gear is provided with a time-delay assembly, the inside of the shell is fixedly connected with a fixed rod, and the bottom of the fixed rod is fixedly connected with a contact point; through motor one, the bevel gear, Under the interaction between the delay component, the fixed rod, the contact, the rotating shaft, the wire wheel, the charging line, and the charging gun, when the user does not receive the charging line into the shell due to negligence or other reasons, such a structure It can play a role of delay between them, so that the charging cable can be retracted after the user leaves, avoiding the immediate retraction and causing personal injury, which is more in line with the actual situation.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a charging line recovery device for new energy vehicles based on capacitive sensing. Background technique [0002] New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. A pure electric vehicle is a vehicle that uses a single battery as the energy storage power source. It uses the battery as the energy storage power source, and supplies electric energy to the motor through the battery to drive the motor to run, thereby driving the car. The advantage is that the technology is relatively simple and mature, and it can be charged wherever there is a power supply. The disadvantage is that the energy stored per unit weight of the battery is too little, and because the battery of an electric vehicle is more expensive and has not formed an eco...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a new energy vehicle charging line recovery device based on capacitive sensing, which has the advantages of timely recovery and reduced consumption, and solves the problem that most of the existing charging piles are exposed to the outside world. , and the charging cable will also have a long section exposed outside the charging pile to achieve the purpose of convenient charging, but because the charging cable is exposed outside for a long time, different weather conditions will cause the rubber protective layer on the outside of the charging cable to appear. Some problems that threaten the safety of electricity use, such as cracking and falling off, will cause greater safety hazards, and long-term exposure and bending use will also reduce the service life of the charging line, which will cause manufacturers. production cost issue
