A mobile car charging pile

Abstract

The invention belongs to the technical field of charging piles, and is specifically a mobile charging pile for automobiles; it includes a pile body, a wire is connected to the pile body, a charging head is connected to one end of the wire, and a charging head is fixedly connected to both sides of the charging head. Contact plate, electromagnets are embedded on the surface of the two contact plates, and pressure sensors are bonded to the surface of the two contact plates; a U-shaped groove is arranged at the bottom of the pile body; When the vehicle will be far away from the pile body, because the wire has a force to hinder the movement of the charging head, when the charging hole is on both sides of the vehicle, the pressure difference between the two pressure sensors will become larger and larger. When the charging hole is at the vehicle and the rear of the vehicle, The pressure values ​​monitored by the two pressure sensors change a lot at the same time. The controller controls the electromagnet to power off, so that the charging head will no longer suck the vehicle at the charging hole, and the charging head will be separated from the charging hole when the vehicle is moving, protecting the Charging heads and charging holes on electric vehicles.

Description

technical field [0001] The invention belongs to the technical field of charging piles, in particular to a mobile charging pile for automobiles. Background technique [0002] Electric vehicles are an emerging technology that has been vigorously developed in China in recent years. By rationally using electric energy to drive vehicles, fuel-driven vehicles can be avoided, and the goals of energy saving and environmental protection can be achieved. However, the use of electric vehicles is accompanied by the problem of charging electric vehicles. Because electric vehicles are emerging technologies, many related technologies are immature, including the manufacturing technology of car charging piles, which makes the cost of car charging piles expensive. Now the car charging piles on the market are expensive and most of them are fixed charging piles. The requirement of using multiple vehicles at the same time requires the installation of multiple car charging piles, which greatly i...

Problems solved by technology

[0005] In order to achieve the above object, the present invention provides the following technical solutions: a mobile car charging pile, including a pile body, a wire is connected to the pile body, a charging head is connected to one end of the wire, and both sides of the charging head are fixedly connected with Contact plate, electromagnets are embedded on the surface of the two contact plates, and pressure sensors are bonded to the surface of the two contact plates; a U-shaped groove is arranged at the bottom of the pile body, and two clamping plates are fixedly connected to the bottom of the pile body. The clamping plates are respectively attached to the two side walls of the inner side of the U-shaped groove. Two rows of balls are embedded in the wall thickness of the bottom of the pile body. Two guide grooves are opened on the top of the U-shaped groove. In the groove; the inner bottom of the U-shaped groove is provided with a plurality of limit holes, and a limit rod is inserted into one of the limit holes. The wall thickness of the body moves up and down and the lowest point of the movement of the top of the limit rod is within the wall thickness of the pile body; when working, the existing mobile charging pile can be moved horizontally to a certain position after charging the current electric vehicle. Charging another electric vehicle perfectly solves the problem of inconvenient charging piles. Due to the slow charging efficiency of existing electric vehicles, it often takes several hours to charge the battery fully. In order to prevent the external force from causing the charging head to fall off, the charging The head is clamped tightly at the charging hole of the electric vehicle, but if there is a strong wind and rain during the charging process of the electric vehicle, the electric vehicle forgets to tighten the handbrake, and the car will roll under the action of the strong wind, which will cause The charging head and the charging hole have a large breakaway force, which causes the hard force damage of the charging head or the charging hole. The main solution of the invention is how to separate the charging head from the electric vehicle before the vehicle slips and the charging head breaks, so as to protect the charging. head and the charging hole on the electric vehicle; the specific measures and working process are as follows: the front of the vehicle is facing the front side of the pile body, and the charging hole is on both sides of the vehicle. An electromagnet is embedded on the contact side of the car. After the charging head is inserted into the charging hole of the electric car, the electromagnet is energized to generate magnetism, which is adsorbed on the surface of the vehicle near the charging hole, so that the contact plate is close to the surface of the vehicle. The two contact plates The two pressure sensors can have the same pressure value. When the vehicle is slipping, the vehicle will be far away from the pile body, and the vehicle will drive the charging head to straighten the wire. , so the wire is pulled on the charging head, the contact plate close to the pile body will squeeze the vehicle surface, and the contact plate far away from the pile body will be separated from the vehicle surface, causing the pressure difference between the two pressure sensors to become larger and larger. When the pressure difference is greater than After the preset value, the controller will control the electromagnet to power off, the charging head will no longer be tightly inserted into the charging hole, and the charging head will be separated from the charging hole when the vehicle is moving, protecting the charging head and the charging hole on the electric vehicle. At the vehicle and the rear of the vehicle, only when the pressure values ​​monitored by the two pressure sensors change a lot at the same time, the controller controls the electromagnet to cut off the power, so that the charging head will no longer suck the vehicle at the charging hole
