Mode for Carrying Out the Invention

[0020] Hereinafter, the vehicle 100 according to the embodiment will be described with reference to the drawings. The arrows FR, UP, and RH shown in each figure indicate the front side, the upper side, and the right side of the vehicle 100, respectively. Also, the opposite directions of the arrows FR, UP, and RH indicate the rear side, the lower side, and the left side. Hereinafter, when simply using the directions of front and rear, left and right, and up and down for description, unless otherwise specified, they indicate the front and rear in the front-rear direction of the vehicle 100, the left and right in the left-right direction, and the up and down in the up-down direction.

[0021] As shown in FIG. 1, the vehicle body 10 of the vehicle 100 includes a front compartment 11, a passenger compartment 12, and a trunk 14. The front compartment 11 is disposed in the front of the vehicle body 10 and is an internal space for accommodating a drive unit such as an engine or a motor.

[0022] The passenger compartment 12 is disposed in the center of the vehicle body 10 and is a space for the driver and passengers to board. Inside the passenger compartment 12, a driver's seat 21, a passenger seat 22, and a rear seat 25 are disposed. Note that FIG. 1 is a view with the roof removed so that the inside of the passenger compartment 12 can be seen.

[0023] The trunk room 14 is located at the rear of the vehicle body and is a space for loading luggage inside. The trunk room 14 is covered by a rear hood (not shown). The front end of the rear hood is rotatably attached to the vehicle body 10, and the rear end moves up and down to open and close the trunk room 14. Note that Fig. 1 is a view showing the interior of the trunk room 14 with the rear hood removed.

[0024] Next, the detailed structure of the trunk room 14 will be described with reference to Figs. 1 and 2. As shown in Fig. 2, the trunk room 14 includes a rear floor panel 15 which is a component of the vehicle body 10. The rear floor panel 15 is a metal plate member. The rear floor panel 15 is composed of flat plate portions 15A at both ends in the width direction, a recess 15C provided at the center in the vehicle width direction, and step portions 15B (left and right portions) between the left and right flat plate portions 15A and the recess 15C. The flat plate portion 15A is connected to the lower end of the side wall 16 of the trunk room 14. An outer panel 17 that constitutes the design surface of the side surface of the trunk room 14 is attached to the outside in the vehicle width direction of the side wall 16. The recess 15C is a space for accommodating the spare tire 50 inside. The step portion 15B is a region that is slightly recessed from the outer flat plate portion 15A, and the depth of the recess is smaller than that of the recess 15C. A right cover plate 31 is mounted on the upper side of the region between the right portion of the step portion 15B and the right end portion (the portion close to the recess 15C) of the left portion of the step portion 15B. The right cover plate 31 also covers the upper surface of the recess 15C. Further, a left cover plate 32 is mounted on the upper side of the left region of the step portion 15B. The right cover plate 31 and the left cover plate 32 are thick plate-shaped charged members made of foamed resin and constitute the cover plate 30. The region D of the step portion 15B and the recess 15C that faces the lower outer surface 31A of the right cover plate 31 and the lower outer surface 32A of the left cover plate 32 constitutes the opposing portion of the vehicle body 10 that faces the outer surface 30A of the cover plate 30.

[0025] Between the right cover plate 31 and the stepped portion 15B, between the left cover plate 32 and the stepped portion 15B, and between the spare tire 50 housed in the recess 15C and the right cover plate 31, the main body 41 of the antistatic sheet, the nonwoven fabric 40, is sandwiched. The peripheral edge 42 of the nonwoven fabric 40 slightly protrudes from the stepped portion 15B onto the flat portion 15A. Thus, the nonwoven fabric 40 covers the entire area D of the surface of the stepped portion 15B and the recess 15C facing the lower outer surface 30A of the cover plate 30. In FIG. 2, the area D in the vehicle width direction is illustrated, but the same applies to the vehicle front-rear direction. The nonwoven fabric 40 covers the entire surface of the stepped portion 15B, the recess 15C, and the spare tire 50 facing the lower outer surface 30A of the cover plate 30.

[0026] Next, referring to FIGS. 1 and 3, the detailed structure of the rear seat 25 will be described. The rear seat 25 includes a frame 26 mounted on the floor panel 13, a cushion 23 mounted on the frame 26, and a backrest 24. The floor panel 13 is a metal plate member and is a component of the vehicle body 10. The cushion 23 is an antistatic member made of foamed resin. Inside the frame 26, a battery 27 for driving a motor is stored. A nonwoven fabric 43 is disposed between the lower surface of the cushion 23 and the upper surface of the battery 27, and between the lower surface of the cushion 23 and the frame 26. In this way, the nonwoven fabric 43 is disposed between the floor panel 13 and the cushion 23 and between the lower surface of the cushion 23 and the frame 26 so as to be separated from the floor panel 13 and contact the lower outer surface of the cushion 23. Also, the nonwoven fabric 43 is disposed so as to cover the area E of the floor panel 13 facing the entire lower outer surface of the cushion 23. In FIG. 3, the area E in the vehicle width direction is illustrated, but the same applies to the vehicle front-rear direction. The nonwoven fabric 43 covers the floor panel 13 facing the entire lower outer surface of the cushion 23.

[0027] Next, with reference to FIG. 4, the operation / effects of the felt cloth 40 attached to the trunk room 14 will be described. When the vehicle 100 travels, the cover plate 30 made of foamed resin, which is likely to be charged due to external factors such as high-voltage electric wires, becomes charged. In this case, as shown in FIG. 4, negative static electricity is charged on the outer surface 31A of the right cover plate 31. Although the reason why the charged potential of the vehicle body 10 is maintained at zero potential by attaching the felt cloth 40 has not been elucidated in detail, it is considered to be due to the absorption of electromagnetic waves by the felt cloth 40 having moisture retention and air permeability as follows.

[0028] The felt cloth 40 is composed of natural fibers near zero potential in the triboelectric series. Also, the felt cloth 40 has moisture retention and air permeability. The felt cloth 40 covers the stepped portion 15B facing the lower outer surface 31A of the right cover plate 31. Thereby, the felt cloth 40 suppresses electrostatic induction between the stepped portion 15B disposed close to the right cover plate 31. Thereby, charging of the stepped portion 15B due to the negative static electricity charge on the right cover plate 31 is suppressed. Similarly, the felt cloth 40 covers the concave portion 15C facing the outer surface 31A of the right cover plate 31, and the left cover plate 32 covers the stepped portion 15B facing the outer surface 32A. Thus, the felt cloth 40 covers the entire surfaces of the stepped portion 15B and the concave portion 15C facing the lower outer surface 30A of the cover plate 30. Thereby, charging of the rear floor panel 15 due to the charge charged on the outer surface 30A of the cover plate 30 is suppressed. And charging of positive static electricity throughout the rear floor panel 15 can be suppressed, and the charged potential of the vehicle body 10 can be suppressed. Also, the felt cloth 40 can suppress charging of the stepped portion 15B due to friction between the right cover plate 31 and the stepped portion 15B. Thereby, the felt cloth 40 can effectively maintain the charged potential of the vehicle body 10 at zero potential.

[0029] Also, according to the research of the inventors, as shown in FIG. 5, it has been confirmed that when the moisture retention and air permeability of the felt cloth 40 increase, the potential of the vehicle body 10 decreases. From this, it can be seen that in order to obtain the above effects, it is necessary for the felt cloth 40 to have moisture retention and air permeability.

[0030] On the other hand, as shown in FIG. 6, in the case of a conventional vehicle 110 without the felt cloth 40, the potential of the vehicle body 10 increases. Although the reason for this has not been elucidated in detail, it is considered to be due to the following reasons.

[0031] Due to the negatively charged static electricity on the right cover plate 31, electrostatic induction occurs in the air layer between the right cover plate 31 and the stepped portion 15B, and the stepped portion 15B is charged with positive static electricity. For this reason, in the conventional vehicle 110, the potential of the vehicle body 10 increases. In contrast, in the vehicle 100 of the embodiment, since the felt cloth 40 suppresses the electrostatic induction from the cover plate 30 to the rear floor panel 15, the charged potential of the vehicle body 10 can be maintained at zero potential.

[0032] Also, the felt cloth 43 attached to the rear seat 25 is arranged so as to cover the entire surface of the floor panel 13 facing the entire outer surface below the cushion 23. Thereby, the electrostatic induction between the cushion 23 and the floor panel 13 is suppressed. For this reason, it is possible to suppress the floor panel 13 from being charged by the charge charged on the cushion 23, and the charged potential of the vehicle body 10 can be maintained at zero potential.

[0033] In this way, the vehicle 100 of the embodiment can effectively maintain the charged potential of the vehicle body 10 at zero potential by the felt cloths 40 and 43, so that it is possible to suppress the charged potential of the vehicle body 10 from affecting the control system and sensors and to exhibit the original control performance of the vehicle 100. Further, since the vehicle 100 can suppress the positive static electricity from being charged on the outer surface of the vehicle body 10, it is possible to suppress the generation of separation flow on the surface of the vehicle body 10, exhibit the original aerodynamic performance of the vehicle 100, and improve the fuel efficiency.

[0034] In the above description, the antistatic sheet was described as being composed of the nonwoven fabric 40. However, it is not limited to this as long as it is composed of natural fibers near zero potential in the triboelectric series and has moisture retention and breathability. For example, it may be composed of a cotton fabric or Japanese paper. Also, as the antistatic sheet, a cloth containing a softener for washing containing a surfactant may be used for a cotton towel. In this case, the electromagnetic wave absorption performance of the cloth is enhanced by the action of the surfactant, and it is possible to suppress the charging of the constituent members of the vehicle body 10 due to the charges charged on the charged member.

[0035] Also, in the above description, it was described that the nonwoven fabric 43 is arranged below the cushion 23 of the rear seat 25. However, it is not limited to this, and the nonwoven fabric 43 may be arranged below the cushions of the driver's seat 21 and the passenger seat 22. Thereby, it is possible to suppress the charging of the floor panel 13 due to the charges charged on the cushions of the driver's seat 21 and the passenger seat 22, and to reduce the charging potential of the vehicle body 10. Then, the original control performance and aerodynamic performance of the vehicle 100 can be effectively exhibited.
