A new energy vehicle charging device with automatic control of wire take-up

Abstract

The invention discloses a new energy car charging device capable of automatically controlling winding up. The new energy car charging device comprises a charging pile body, and a sliding groove is transversely formed in the middle position in the charging pile body. A first cavity is formed in the position, above the left side of the sliding groove, of the charging pile body, and a second cavity is formed in the position, below the right side of the sliding groove, of the charging pile body. A winding up cavity is formed in the position, at the bottom of the second cavity, of the charging pile body, a transmission cavity is formed in the position above the right side of the first cavity, and a first screw is arranged in the sliding groove. The right side end of the first screw is in power connection with a first motor, a movable rod upwards extending and a movable block arranged on the right side of the movable rod are connected to the first screw in a threaded fit mode, the upwards-extending section of the movable rod extends into the first cavity, and an inner spline shaft is connected into the movable rod in a rotating fit mode. A first conical wheel is fixedly arranged at the right side end of the inner spline shaft, the inner spline shaft is internally connected with an external spline shaft in a matched mode, and a second conical wheel is connected to the position above the right side of the first conical wheel in an engaged mode. The new energy car charging device is simple in structure and convenient to operate, rainwater is prevented from falling into the charging pile body, and working efficiency and safety are improved.

Description

technical field [0001] The invention relates to the technical field of charging for new energy vehicles, in particular to a charging device for new energy vehicles that automatically controls the take-up of wires. Background technique [0002] At present, energy saving, environmental protection, and low-carbon life are hot topics. In order to achieve the goal of emission reduction, the country vigorously promotes electric vehicles. Electric vehicles do not emit carbon dioxide and have no tail gas pollution. They are very beneficial for controlling environmental pollution and reducing tail gas emissions, and electricity can be obtained through a variety of energy sources, such as thermal power, hydropower, nuclear power, wind power and solar power.

Problems solved by technology

[0003] The existing charging piles need to manually put the charging cable back into the charging pile after the charging is completed, but the charging wire is generally long, which brings great inconvenience to the user, and the current charging pile does not have automatic winding The function of the wire, the user often does not place the wire according to the requirements after use, but throws the wire on the ground at will; in this way, the wire is vulnerable to various unexpected stresses, such as people trampling on it, cars running over it, etc., resulting in the outer insulation of the wire Damage, resulting in reduced life of the wire, resulting in accidents such as electric shock
