  The present invention relates to a charging device for a vehicle such as an electric vehicle, for example. For a vehicle equipped with a shock absorber provided in a charger, the vehicle and the charger can be prevented or reduced from damage, and the cause can be investigated by a collision detection function. The present invention relates to a charging device.

  In recent years, vehicles (electric vehicles) that use electricity that does not emit exhaust gas as a power source are becoming widespread. When electricity is used as a power source, the vehicle is provided with a battery, an electric motor, and the like, and in order to supply electricity to the battery, a vehicle charging device is required outside.

  Several requirements are required for a vehicle charging device, but regarding the installation location, it is necessary that the electrical system is wired. Also, compared to a gas station that supplies fuel to an automobile that uses liquid fuel, it takes a long time to supply power, so it is necessary to secure a place to hold the vehicle during this time. Specifically, a place for parking a vehicle such as a shopping mall parking lot, a highway parking lot, a public parking lot, and a corporate parking lot is required, and the vehicle charging device is installed here.

  In addition, as a function required for the vehicle charging device, it receives power from the electric system, adjusts the value of DC power or AC power that matches the specifications of the vehicle battery, and passes through the charging cable and charging connector. It will be supplied to the battery of the vehicle.

  For this reason, a vehicle charging device is often equipped with a monitor to clearly indicate the charging status and the charging operation method, and is provided with a charging start button and a charging end button for charging start and end of charging. In some cases, it is necessary to provide an emergency stop button or the like for operating an electric breaker for cutting off the connection with the electric system.

  As described above, the vehicular charging device is a high-voltage, precision machine installed in the parking lot. On the other hand, the parking space tends to become narrower as the city center becomes smaller. It is being promoted by equipment manufacturers. Under such a parking environment, in order to designate a parking position of a narrow parking lot, the vehicle charging device including a sensor for detecting the position of the vehicle is disclosed in Patent Document 1, Patent Document 2, and Patent It has been proposed by a technique such as Document 3.

  The vehicle charging device cannot be charged unless the charging cable is lengthened unless it is installed near the vehicle in a predetermined parking space. Conversely, when the charging cable is long, the mass of the charging cable increases, making it difficult for the user to carry and reducing convenience. Therefore, the installer of the vehicle charging device often has to install the vehicle charging device in the vicinity of a place where a slight space is provided with the vehicle.

  Further, it is advantageous to install the vehicle charging device in the vehicle approach direction. If it is going to arrange | position the charging device for vehicles efficiently in a parking lot, it takes a place in the form in which a vehicle is arranged in parallel with a fueling machine stand like a gas station. In addition, the power supply port of an electric vehicle is often installed in a motor part before and after the vehicle.

  Thus, the vehicle charging device is often provided in the vehicle approach direction, and there is a relationship that the convenience is higher as the space therebetween is narrower. As a result, the vehicle charging device is highly likely to collide with the vehicle, and it is often necessary to provide a collision prevention rod in front of the vehicle charging device. However, in order to provide the collision prevention rod, an additional installation space is required, and the vehicle charging device may not be installed because the installation space is insufficient.

  Moreover, there are few places where there are many extra parking spaces in the parking lot in the city center, and it is difficult to install a plurality of vehicle charging devices in the parking lot. If multiple vehicles want to use the charging device for a vehicle, use the charging device for the vehicle because the parked vehicle must be moved for another vehicle as soon as the previous vehicle finishes charging. Problems are likely to occur in the operation of the system.

  The object of the present invention is to provide the vehicle charging device with a collision buffer, a collision detection function and a monitoring camera so that the vehicle charging device can be installed even in a narrow parking space, and can efficiently operate the vehicle charging device. It is providing the charging device for vehicles.

  In order to solve the above problems, in the present invention, there is provided a charging device for a vehicle for supplying power to a vehicle parked in a parking space partitioned by a frame line, wherein the vehicle is charged for parking in the parking space. In the vehicle charging device that is adapted to enter toward the device, the vehicle charging device includes a main body portion on which the vehicle charging equipment is mounted, and a collision buffer provided in front of the main body portion with respect to the vehicle entering direction. It is characterized by having.

  Further, the vehicle charging device includes an intrusion detection sensor that detects an approach due to an approach of the vehicle, and a vehicle approach notification unit that notifies the approach of the vehicle by the operation of the intrusion detection sensor.

  In addition, the vehicle charging device includes a controller inside the main body portion where the vehicle charging equipment is mounted and monitors and controls the charging process, and the controller transmits a monitoring control result of the charging process in cooperation with a remote personal computer. And the instruction from the personal computer is reflected in the charging process.

  Further, the vehicle charging device includes a monitoring camera for monitoring the charging process, and the monitoring video is displayed and recorded on a distant personal computer via the controller.

  In addition, the vehicle charging device is characterized in that a vehicle movement instruction from an administrator who monitors display contents of a personal computer is communicated to the vehicle operator via a personal computer and a controller so as to move the vehicle.
