Summary of the Invention

Problems to be Solved by the Invention

[0004] In a vehicle equipped with an engine, it is common to refuel by so-called side attachment to a fuel dispenser installed at a gas station. Therefore, the fuel filler port is arranged at the rear part of the side surface on the right or left side of the vehicle body. On the other hand, considering the safety when refueling and charging simultaneously, the charging port is provided at a position as far as possible from the fuel filler port. In the hybrid vehicle of Patent Document 1, the charging port is provided at the rear part of the side surface opposite to the side surface where the fuel filler port is provided. On the other hand, recently, there have been an increasing number of vehicles with so-called rear doors for getting in and out of the rear seats as sliding doors. In this type of vehicle, when the sliding door is opened, after the door moves slightly parallel to the outside of the vehicle body, it moves backward parallel to the side surface of the vehicle body. Therefore, the door will be parallel to the rear side surface of the vehicle body and cover that side surface. Therefore, if a vehicle having this type of sliding door is configured as a hybrid vehicle, with its fuel filler port arranged at the rear part of one side surface and its charging port arranged at the rear part of the other side surface, the fully opened rear door will interfere with these fuel filler ports and charging ports, or interfere with the fuel nozzle and charging plug. Therefore, it is impossible to refuel and charge simultaneously, or if refueling and charging are to be performed simultaneously, the rear door cannot be opened, or has to be in a semi-open state, which may cause inconvenience in getting in and out of the rear seat, and the convenience of the vehicle may be impaired.

[0005] The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a hybrid vehicle capable of ensuring the convenience of the vehicle, such as being able to refuel and charge simultaneously without causing inconvenience in getting in and out of the rear seat.

Means for Solving the Problem

[0006] In order to achieve the above object, the present invention provides a hybrid vehicle comprising an internal combustion engine and an electric motor as driving power sources, and configured such that the left and right doors for the rear seats open by translating in parallel to a position covering the surface of the rear part of the side surface of the vehicle body. The hybrid vehicle has a fuel filling port for supplying fuel for the internal combustion engine and a charging port for charging electric power for the electric motor. The fuel filling port is provided at a position opening on the surface of the rear part of either the left or right side surface of the vehicle body, and the charging port is provided at a position where a cable can be connected from the back side of the vehicle body.

Advantages of the Invention

[0007] In the hybrid vehicle according to the present invention, when refueling and charging are performed simultaneously, the lid of the fuel filling port is opened and the fuel nozzle is inserted into the fuel filling port, and the lid of the charging port is opened and the charging plug is inserted, so that these protrude outside the vehicle body. However, since there is no particularly protruding portion on the side surface opposite to the side surface where the fuel filling port is provided, the rear door on that side surface can be slid to full open. Further, since the charging port is configured to connect a cable from the back side of the vehicle body and does not interfere with the rear door, it does not hinder the entry and exit to the rear seat. Eventually, in the hybrid vehicle of the present invention, it is possible to perform refueling and charging simultaneously without hindering the entry and exit to the rear seat.

Embodiments for Carrying Out the Invention

[0009] Next, the present invention will be described based on the embodiments shown in the drawings. It should be noted that the embodiments described below are merely examples when the present invention is embodied, and do not limit the present invention.

[0010] Fig. 1 schematically shows a hybrid vehicle (hereinafter sometimes simply referred to as a vehicle) 1 according to an embodiment of the present invention. The hybrid vehicle 1 includes an internal combustion engine (hereinafter referred to as an engine) 2 such as a gasoline engine and an electric motor (hereinafter referred to as a motor) 3 such as a motor or a motor-generator as driving power sources. The hybrid type may be any of a series hybrid, a parallel hybrid, a series-parallel hybrid, and the like. A fuel tank 4 for storing fuel for the engine 2 and a power storage device 5 for supplying power to the motor 3 and charging the power generated by the motor 3 are mounted on the vehicle 1. Note that the fuel tank 4 includes a fuel pump (not shown) for sending fuel to the engine 2. The power storage device 5 includes a power storage device such as a secondary battery or a capacitor and control devices (not shown respectively) for charge and discharge.

[0011] The vehicle 1 is provided with left and right front (front) doors 6l and 6r for getting on and off the driver's seat and the passenger seat, and left and right rear (rear) doors 7l and 7r for getting on and off the rear seat. The front doors 6l and 6r are of a type that rotate about a hinge to open and close, while the rear doors 7l and 7r are slide doors that move parallel to the front-rear direction along the left and right side surfaces of the vehicle body. Therefore, when the rear doors 7l and 7r are opened, the rear part of the side surface of the vehicle body is covered by the rear doors 7l and 7r.

[0012] On the rear part of one side of the vehicle body (for example, the rear part of the right side), a fuel filler port 8 is provided. The fuel filler port 8 is a part where a fuel nozzle (not shown) for supplying fuel to the above-mentioned fuel tank 4 is inserted. Similar to that provided in a conventional general vehicle, it is closed by a cap and is configured to be opened and closed by a lid (each not shown) that forms part of the vehicle body side surface. The location where this fuel filler port 8 is provided is a location covered by the rear door 7r when the right rear door 7r is fully opened. Therefore, when refueling, since the open lid and the fuel nozzle inserted into the fuel filler port 8 protrude to the outer surface side, these will interfere with the rear door 7r. That is, when refueling, the rear door 7r (or 7l) on the side where the fuel filler port 8 is provided cannot be fully opened. Fig. 1 shows a state where the right rear door 7r is half opened. Note that the reference sign Sh shown in Fig. 1 indicates the steering wheel.

[0013] Also, a charging port 9 is provided on the rear side of the vehicle body (the left side in Fig. 1). The charging port 9 is electrically connected to the above-mentioned power storage device 5 and is a connection part for connecting an external power source (not shown) and charging the power storage device 5 by inserting a plug 11 provided at the tip of a cable 10. This charging port 9 is generally closed by an insulating cap and is also configured to be closed by a lid (each not shown) for protecting the opening.

[0014] Furthermore, regarding the position where the charging port 9 is provided, the charging port 9 can be provided at an appropriate position on the rear side according to the vehicle type of the vehicle 1 and the structure of the vehicle body. For example, in a vehicle 1 having a door (back door) provided on the rear side, the charging port 9 can be provided on the outer surface part of that back door. Also, in the embodiment of the present invention, the charging port 9 only needs to be provided at a position where the cable 10 can be connected from the rear side of the vehicle body. Therefore, the charging port 9 may be provided at a location where the cable 10 can reach when opening the back door or the trunk lid (not shown), such as the inner surface of the rear part of the passenger compartment or the luggage compartment. Furthermore, the charging port 9 can also be provided on the rear bumper (not shown).

[0015] In addition, when the charging port 9 is provided in a hatchback-type back door or trunk lid, it is preferable to perform control to prohibit the opening and closing of the back door or trunk lid while the cable 10 is connected to the charging port 9. On the other hand, if the back door has a double-hinged structure, it is also possible to allow the back door to be opened and closed with some slack in the cable 10. Furthermore, when the cable 10 for charging is mounted on the vehicle 1, it is preferable to configure the cable 10 to be accommodated on the rear side of the vehicle from the power storage device 5, such as securing a space inside the rear bumper and accommodating the cable 10 in that space.

[0016] When charging is performed, the lid of the charging port 9 and the cable 10 will protrude outside the vehicle body, and depending on the structure of the vehicle body, it may become impossible to open the back door or trunk lid. However, on the side surface of the vehicle body opposite to the fuel filler port 8 described above, no protruding portion is generated particularly during refueling and charging, so the rear door 7l on the side opposite to the fuel filler port 8 can be fully opened as usual. This state is shown in FIG. 1. As described above, according to the structure of the vehicle 1 in the embodiment of the present invention, even when refueling and charging are being performed simultaneously, either the left or right rear door 7l (or 7r) can be fully opened, so there is no particular hindrance to getting in and out of the rear seat (not shown), and good convenience of the vehicle 1 can be ensured.
