Description

  The present invention relates to a vehicle body structure of an electric vehicle equipped with a motor as a power source for traveling.

  In a commercial vehicle such as a bus having a passenger seat for passengers, a layout in which a driver's seat and a front passenger seat are disposed in front of the passenger seat is adopted. In particular, in a small bus generally called a micro bus, the driver's seat can get on and off via a dedicated door, but the passenger seat is not provided with a dedicated door such as the driver's seat. From the passenger entrance, it is necessary to access the passenger seat via an intermediate passage provided between the driver's seat and the passenger seat.

  Patent Document 1 discloses an example of a vehicle body structure in a micro bus on which an engine is mounted as a power source for traveling.

Japanese Patent Application Laid-Open No. 11-91630

  In Patent Document 1 above, since the engine mounted as a power source for traveling is disposed below the intermediate passage between the driver's seat and the front passenger seat, the floor surface of the intermediate passage is higher than the surrounding area. . Further, since the driver's seat and the passenger's seat are disposed on the front fender 35 of the front wheel, the height of the floor near this also naturally becomes high. Therefore, when accessing the front passenger seat from the passenger seat side, it was necessary to get over the large step.

  By the way, in recent years, in various vehicles from an environmental point of view, there has been progressed widespread use of electric vehicles adopting a motor instead of or in addition to a conventional engine as a driving power source. However, in the small bus such as the aforementioned micro bus, the use of electric vehicles has not progressed, and a new vehicle layout is expected.

  SUMMARY OF THE INVENTION At least one embodiment of the present invention has been made in view of the above-mentioned circumstances, and provides a vehicle body structure of an electric vehicle having good accessibility to a front passenger seat disposed in front of a passenger seat in a small bus such as a micro bus. Intended to be provided.

In order to solve the above problems, the vehicle body structure of an electric vehicle according to at least one embodiment of the present invention,
A vehicle body structure of an electric vehicle in which the passenger seat can be accessed from the passenger seat via an intermediate passage between a driver seat and a front passenger seat arranged on a traveling wheel in front of the passenger seat,
At least a portion of the floor surface of the intermediate passage is continuously configured with the floor surface of the passenger seat, and a reinforcement member extending continuously in the vehicle width direction at the vehicle rear portion of the driver seat and the passenger seat Equipped with

  According to such a configuration, in the electrically powered vehicle, since the motor is mounted as a power source for traveling, it is not necessary to arrange the engine below the intermediate passage as in the prior art. Therefore, by at least a part of the floor surface of the intermediate passage being continuously formed with the floor surface of the passenger seat, the height of the floor surface of the intermediate passage can be reduced. As a result, in a small bus such as a micro bus, it is possible to have good access to the front passenger seat disposed in front of the passenger seat. In the present specification, "consecutively constructed" is not limited to the case where at least a part of the floor surface of the passenger seat and the floor surface of the intermediate passage are flush, and is smaller than conventional engine vehicles It is the meaning including the case where there is a level difference.

However, the dimensions, materials, shapes, relative arrangements, etc. of components described in these embodiments or shown in the drawings are not intended to limit the scope of the present invention to this, but merely illustrative examples. It is only

  FIG. 1 is a schematic configuration view showing a configuration of an electric vehicle to which a vehicle body structure of the electric vehicle according to an embodiment of the present invention is applied.

  Electric powered vehicle 100 is a vehicle equipped with an electric motor (not shown) as a power source for traveling. The electric motor generates driving power by being driven using electric power stored in a battery (not shown) mounted on electric powered vehicle 100, and is transmitted to the traveling wheels, whereby the traveling of electric powered vehicle 100 is performed. To be realized.

  The electric vehicle 100 is a small bus for transporting passengers, and the vehicle body 1 has the driver's seat 2 and the passenger's seat 4 arranged in line in the vehicle width direction on the front side of the vehicle, and the passengers on the rear side thereof. It has a layout provided with a passenger seat area 7 in which a plurality of passenger seats 6 that can be seated are disposed. In particular, the electric vehicle 100 is a so-called micro bus, and the driver can get in and out of the driver's seat side door 12 provided on the side of the driver's seat 2, but the passenger of the passenger seat 4 The passenger seat 4 is configured to be accessible from the passenger entrance 13 provided on the rear side of the seat 4 through the intermediate passage 9 provided between the driver's seat 2 and the passenger seat 4 (see the arrow in FIG. 1) .

  The driver's seat 2 and the passenger's seat 4 are disposed on the front fender 35 of the front wheel (not shown), so the floor surface is higher than the passenger's seat area 7.

  By the way, in the conventional vehicle equipped with an engine as a power source for traveling in such a micro bus, the layout in which the engine is disposed below the intermediate passage 9 is typical. Since the engine is a large-sized structure, the floor surface of the intermediate passage 9 is higher than the surrounding area due to the presence of the engine (see Patent Document 1 above), and the passenger of the passenger seat 4 starts from the passenger seat area 7 It was an obstacle when accessing 4. In the electric vehicle 100 according to the present embodiment, such a problem can be suitably solved by adopting a vehicle body structure described below.

  FIG. 2 is a cross-sectional view showing the vehicle body structure of the electric vehicle 100 of FIG. 1 from the side.

  Although electric motor 100 employs an electric motor as a power source for traveling as described above, the size of the motor is smaller than that of the engine used in the conventional vehicle, so the installation location is not limited to the lower part of intermediate passage 9 . For example, it is also possible to arrange the motor behind the intermediate passage 9. In electric powered vehicle 100, by introducing a layout in which the electric motor is installed in a place different from intermediate passage 9 in this manner, the floor surface height of intermediate passage 9 approaches the floor surface height of passenger seat area 7 be able to.

  As shown in FIG. 2, at least a part of the floor 5 a of the intermediate passage 9 is continuously formed with the floor 5 b of the passenger seat area 7. In the present embodiment, in particular, the floor 5a of the intermediate passage 9 includes the first floor 5a1 on the passenger seat area 7 side and the second floor 5a2 forward of the first floor 5a1. A step 5a3 is formed between the first floor 5a1 and the second floor 5a2. The first floor surface 5a1 is continuously configured with the floor surface 5b of the passenger seat area 7 (in other words, it is flush).

  As described above, in the electric vehicle 100, since the motor is mounted as a power source for traveling, it is not necessary to arrange the engine below the intermediate passage 9 as in the prior art. Therefore, when at least a part of the floor 5 a of the intermediate passage 9 is continuously formed with the floor 5 b of the passenger seat area 7, the height of the floor 5 a of the intermediate passage 9 can be reduced. As a result, in a small bus such as a micro bus, it is possible to have good accessibility to the front passenger seat 4 disposed in front of the passenger seat 6.

  Under the first floor surface 5a1, an EV component 20 constituting an electric circuit related to a motor or a battery mounted on the electric vehicle 100 is disposed. Such an EV component 20 is also smaller in size than the engine, and therefore does not become a factor to increase the height of the floor 5 a of the intermediate passage 9.

  Further, below the second floor surface 5a2, a water-cooling radiator 14 for cooling each component of the electric vehicle 100 including the electric motor or the battery is disposed. Such a radiator 14 tends to be larger in size in the vertical direction than the EV component 20. However, by arranging the radiator 14 in front of the EV component 20, the range in which the intermediate passage 9 bulges is limited to the second floor 5a2. Thus, the range of the first floor 5a1 continuous with the floor 5b of the passenger seat area 7 can be widely secured.

  The radiator 14 may also be disposed further forward than the electric vehicle 100 or the area concerned, since the electric vehicle 100 has a high degree of freedom in layout as compared with the conventional engine vehicle. In this case, as shown in FIG. 4, the step 5a3 can be made more forward, and a wide range of the first floor 5a1 continuous with the floor 5b of the passenger seat area 7 can be secured.

  In the present embodiment, the floor surface 5b of the passenger seat area 7 and the first floor surface 5a1 are flush with each other, but even if there is a small step as compared with the conventional engine vehicle Good. Further, the floor 5 a of the intermediate passage 9 and the floor 5 b of the passenger seat area 7 may be integrally configured, or may be configured by connecting different floor materials.

  FIG. 3 is a perspective view showing a part of the body structure of the electric vehicle 100 of FIG. 1 together with the chassis frame 30. As shown in FIG.

  As shown in FIG. 3, the chassis frame 30 includes left and right side members 31, 31 extending in the front-rear direction, and a plurality of cross members 32 disposed at predetermined intervals in the front-rear direction. It has what is called a ladder frame structure. A body structure is mounted on the chassis frame 30 via a body mount (not shown). In FIG. 3, the front floor portion 33 which is a part of such a body structure is shown supported on the chassis frame 30. As shown in FIG.

  The front floor portion 33 is a driver's seat side panel portion 34a that supports the floor surface of the driver's seat 2, and includes the front fender 35 projecting upward by the right front wheel disposed below. A front passenger seat panel 34b including a front fender 35 that supports the floor surface of the front passenger seat 4 and includes a front fender 35 projecting upward by a left front wheel disposed below the front passenger seat panel 34b; An intermediate passage panel portion 34c supporting the floor surface 5a of the intermediate passage 9 between the driver's seat side panel portion 34a and the passenger seat side panel portion 34b.

The intermediate passage panel portion 34c has a shape corresponding to the floor surface 5a (the first floor surface 5a1, the second floor surface 5a2, and the step 5a3) of the intermediate passage 9 described above. In the example of FIG. 3, an opening 36 is provided in a portion corresponding to the first floor surface 5 a 1 in the middle passage panel portion 34 c.
A reinforcing member 37 for continuously reinforcing the opening 36, the driver's seat side panel portion 34a and the passenger's seat side panel portion 34b is formed to extend in the vehicle width direction. By providing such a reinforcing member 37, body rigidity can be improved, and even when weight is applied to the floor surface 5a of the intermediate passage 9 when the occupant passes the intermediate passage 9, The deformation of the floor 5a can be effectively prevented.

  As described above, according to at least one embodiment of the present invention, it is possible to provide a vehicle body structure of an electric vehicle having good accessibility to a front passenger seat disposed in front of a passenger seat in a small bus such as a micro bus.

  INDUSTRIAL APPLICABILITY The present invention is applicable to an electric vehicle such as a small bus equipped with an electric motor as a power source for traveling.
