Description

[Technical Field]

[0001] The present invention relates to a floor undercover for a vehicle. [Background technology]

[0002] For example, Patent Document 1 discloses a structure in which a portion of the bottom surface of a vehicle floor panel is covered with an undercover. The undercover has a substantially rectangular bottom portion and a peripheral wall portion rising from the periphery of the bottom portion. This structure is provided for the purposes of improving aerodynamics and complying with regulations regarding external noise. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-241792 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the undercover described in Patent Document 1 does not provide any measures to prevent foreign matter that may be placed on the bottom (cover body) of the undercover due to wind or flooding while the vehicle is in motion from accumulating on the peripheral wall.

[0005] In view of the above problems, the present invention has an object to provide a floor undercover for a vehicle that efficiently discharges foreign matter that has been placed on the cover body due to wind caused by running or submersion. [Means for solving the problem]

[0006] In order to solve the above problem, a typical configuration of the present invention is characterized by having a cover body that covers the vehicle floor from below, and a downwardly sloping portion that is continuous with the rear end of the cover body and descends as it goes rearward. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a floor undercover for a vehicle that efficiently expels foreign matter that has been placed on the cover body due to wind caused by running or submersion. [Brief explanation of the drawings]

[0008] [Figure 1] 1 is a rear view of a vehicle to which a vehicle floor undercover according to an embodiment of the present invention is applied. [Figure 2] 2 is a perspective view of the vehicle floor undercover of FIG. 1 as viewed obliquely from above. FIG. [Figure 3] 3 is a cross-sectional view of the vehicle floor undercover shown in FIG. 2 along the line AA. [Figure 4] 2 is a perspective view of the lower surface of the vehicle floor undercover of FIG. 1, viewed obliquely from above. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] One embodiment of the present invention is characterized by having a cover body that covers the vehicle floor from below, and a downwardly inclined portion that is continuous with the rear end of the cover body and descends rearward.

[0010] According to the present invention, the vehicle floor undercover has a downwardly sloping portion that continues from the rear end of the cover body, and does not have, for example, an upwardly protruding portion. Therefore, even if a foreign object is placed on the cover body due to wind or flooding while the vehicle is moving, the foreign object is pushed down along the downwardly sloping portion by wind force, aerodynamic force, or inertial force acting from the front, and falls. As a result, foreign objects that have been placed on the cover body due to wind or flooding can be efficiently removed.

[0011] The cover body may have an upwardly inclined portion having a lower surface that rises rearward, and a groove portion that is continuous with the upwardly inclined portion, extends further rearward, and is continuous with the downwardly inclined portion.

[0012] If the cover main body further has an upwardly inclined portion in this way, the rigidity of the rear end of the vehicle floor undercover can be further improved.

[0013] The front end of the upwardly inclined portion may be located lower than the rear end of the downwardly inclined portion. This configuration prevents the downwardly inclined portion from blocking the airflow that has passed under the front end of the upwardly inclined portion.

[0014] The vehicle floor undercover further has a rear end portion that extends further rearward in a flat plate shape, continuing from the downward inclined portion, and the rear end portion is horizontal and located at the same height as the fore-and-aft center of the lower surface of the upward inclined portion.

[0015] In this way, if the rear end is positioned at the same height as the center of the uphill portion in the fore-and-aft direction, the airflow flowing rearward along the groove from the underside of the uphill portion can be straightened, thereby reducing air resistance.

[0016] It is preferable that the rear end portion has a rearwardly convex shape with a predetermined location between both ends in the vehicle width direction being located rearward of the both ends, and that the downwardly inclined portion, the upwardly inclined portion and the groove portion are formed along the rearwardly convex shape of the rear end portion.

[0017] If the rear end has a rearward-convex shape, the rear edge of the vehicle floor undercover can be set longer than if the rear end were formed in a straight line in the vehicle width direction, which ensures a longer area for foreign objects to be ejected, improving the efficiency of removing foreign objects.

[0018] The vehicle floor undercover may further have a fixing portion provided at a predetermined location on the rear end portion, protruding toward the vehicle floor and fixed to the vehicle floor.

[0019] If the vehicle floor undercover has fixing portions that protrude upward in this way, the positions of the fixing portions can be easily identified when assembling the vehicle floor undercover to the underside of the vehicle floor, improving workability. [Example]

[0020] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Dimensions, materials, and other specific values ​​shown in these embodiments are merely examples for facilitating understanding of the invention and, unless otherwise specified, do not limit the present invention. In this specification and drawings, elements having substantially the same functions and configurations are designated by the same reference numerals to avoid redundant explanation, and elements not directly related to the present invention are not shown.

[0021] Fig. 1 is a rear view of a vehicle 500 to which a vehicle floor undercover 100 according to an embodiment of the present invention is applied. Fig. 2 is a perspective view of the vehicle floor undercover 100 of Fig. 1, viewed obliquely from above. In Fig. 1 and all other drawings, the front-to-rear direction of the vehicle is indicated by arrows F (Forward) and B (Backward), the left and right in the vehicle width direction are indicated by arrows L (Leftward) and R (Rightward), and the up-down direction is indicated by arrows U (Upward) and D (Downward).

[0022] 1, the vehicle floor undercover 100 is disposed on the left side of the vehicle 500 in the vehicle width direction, and has a cover body 102 that covers the floor of the vehicle 500 from below. The vehicle floor undercover 100 is exposed to the outside at the lower end of the vehicle body, and may be exposed to wind, water, snow, etc.

[0023] As shown in Figure 2, the vehicle floor undercover 100 has a front wall portion 110 formed in an upward convex shape at the front end side of the cover main body 102, an outer wall portion 152 formed in an upward convex shape on the outer side of the cover main body 102 in the vehicle width direction, and an inner wall portion 162 extending upward on the inner side of the cover main body 102 in the vehicle width direction.

[0024] Vehicle floor undercover 200 is disposed on the right side of vehicle 500 in the vehicle width direction, and covers the floor from below. Front wall portion 210, cover main body 202, outer wall portion 252, and inner wall portion 262 have the same functions as front wall portion 110, cover main body 102, outer wall portion 152, and inner wall portion 162. For this reason, the following description will focus on vehicle floor undercover 100, and not vehicle floor undercover 200, but the same configurations and functions of vehicle floor undercover 100 will be applied to vehicle floor undercover 200.

[0025] 2, the front wall portion 110 has a raised plate 112 that rises upward on the inner side in the vehicle width direction, and a raised plate 114 that rises upward on the outer side in the vehicle width direction. The upper part of the raised plate 114 is formed by a flange 115 that extends laterally. In addition, a recess 116 that is recessed downward is formed between the raised plate 112 and the raised plate 114. A hole 115a that penetrates in the up-down direction is formed in the flange 115.

[0026] The outer wall portion 152 has a side plate 154 and a flange 156 extending from the upper end of the side plate 154 to the left in the vehicle width direction, i.e., outward in the vehicle width direction. The flange 156 has holes 156a to 156d that penetrate vertically from the front to the rear.

[0027] The inner wall portion 162 has a side plate 164 and a flange 166 extending to the right in the vehicle width direction, i.e., toward the inside in the vehicle width direction, from the upper end of the side plate 164. The flange 166 has holes 166a to 166d that pass through it in the up-down direction, in that order from front to rear.

[0028] The vehicle floor undercover 100 has a fixing portion 140, which will be described later, at the rear of the cover body 102. This fixing portion 140 has a hole 140a formed therein that penetrates in the vertical direction.

[0029] Clips, bolts or the like are inserted into the holes 115a, 156a to 156d, 166a to 166d, 140a described above, and are used to fix the vehicle floor undercover 100 to a member of the vehicle body.

[0030] Fig. 3 is a cross-sectional view taken along line AA of the vehicle floor undercover 100 of Fig. 2. Fig. 4 is a perspective view of the underside of the vehicle floor undercover 100 of Fig. 1, viewed obliquely from above. As shown in Fig. 3, the cover body 102 has an upwardly inclined portion 122 having a lower surface 122b that rises toward the rear. The upwardly inclined portion 122 is formed across the vehicle width. The upper surface 122a of the upwardly inclined portion 122 is formed as a flat surface.

[0031] The cover body 102 has a groove 123 that extends further rearward, continuing from the upwardly inclined portion 122. The groove 123 is formed across the vehicle width direction.

[0032] The vehicle floor undercover 100 also has a downwardly inclined portion 124 that is continuous with the rear end of the cover body 102, i.e., the rear end of the groove portion 123, and slopes downward toward the rear. The downwardly inclined portion 124 is formed across the vehicle width direction.

[0033] The front end 122b1 of the upwardly inclined portion 122 is located at the same height as the underside of the cover body 102, which is located lower than the rear end 124b1 of the downwardly inclined portion 124, which is located at a height M1 based on the underside of the cover body 102.

[0034] The vehicle floor undercover 100 has a rear end portion 126 that extends rearward in a flat plate shape, continuing from the downward inclined portion 124. The rear end portion 126 is formed across the width of the vehicle and extends horizontally. A position 127 of the rear end portion 126 is located at the same height as a center 125 of the lower surface 122b of the upward inclined portion 122 in the fore-aft direction.

[0035] Furthermore, in this embodiment, the vehicle front-rear direction dimension of the rear end portion 126 is set to be longer than the vehicle front-rear direction dimension of the downward inclined portion 124. However, the vehicle front-rear direction dimension of the rear end portion 126 may be set to be the same as the vehicle front-rear direction dimension of the downward inclined portion 124. Furthermore, in this embodiment, the vehicle front-rear direction dimension of the rear end portion 126 is set to be approximately half the vehicle width direction dimension of the lower surface 122b of the upward inclined portion 122, the lower surface 123b of the groove portion 123, and the lower surface 124b of the downward inclined portion 124. However, the vehicle front-rear direction dimension of the rear end portion 126 may be set to be one-third of the vehicle width direction dimension of the lower surface 122b of the upward inclined portion 122, the lower surface 123b of the groove portion 123, and the lower surface 124b of the downward inclined portion 124.

[0036] Fig. 4 is a perspective view of the underside of the vehicle floor undercover 100 of Fig. 1, seen obliquely from above. As shown in Figs. 4 and 2, the rear end 126 has a rearwardly convex shape with a predetermined portion between both ends in the vehicle width direction being located toward the rear of the vehicle. Also, as shown in Fig. 4, the lower surface 124b of the downwardly inclined portion 124, the lower surface 122b of the upwardly inclined portion 122, and the lower surface 123b of the groove 123 are formed along the rearwardly convex shape of the rear end 126. Therefore, the downwardly inclined portion 124, the upwardly inclined portion 122, and the groove 123 are formed along the rearwardly convex shape of the rear end 126.

[0037] 2, the downwardly inclined portion 124 has a side 126p on the outer side in the vehicle width direction and a side 126q on the inner side in the vehicle width direction, which have different inclination angles with respect to the vehicle width direction. As shown in FIG. 1, the angle of the outer side 126p with respect to the vehicle width direction is set to be smaller than that of the inner side 126q with respect to the vehicle width direction.

[0038] 2, the vehicle floor undercover 100 has a fixing portion 140 that is provided at a predetermined position on the rear end portion 126 and protrudes toward the vehicle floor. The fixing portion 140 is fixed to the vehicle floor.

[0039] Next, the operation of the vehicle floor undercover 100 will be described with reference to Figures 2 and 3. When the vehicle is traveling, dirt and snow enter from the front wall 110 side of the vehicle floor undercover 100 and rest on the cover main body 102. Alternatively, when the road is flooded, wastewater and mud enter from the front wall 110 side of the vehicle floor undercover 100 and rest on the cover main body 102 while the vehicle is traveling.

[0040] Foreign matter (dirt, snow, wastewater, mud) placed on this cover body 102 moves along with the air current or water over the upper surface 122a of the upward inclined portion 122 and the upper surface 123a of the groove portion 123 in Figure 3, goes down the upper surface 124a of the downward inclined portion 124, and is discharged rearward along the upper surface 126a of the rear end portion 126.

[0041] In addition, air currents or water flowing rearward below the cover body 102 shown in Figure 2 flow rearward along the lower surface 122b of the upward inclined portion 122, the lower surface 123b of the groove portion 123, the lower surface 124b of the downward inclined portion 124, and the lower surface 126b of the rear end portion 126.

[0042] According to the configuration of this embodiment, the vehicle floor undercover 100 has the downwardly inclined portion 124 that continues from the rear end of the cover main body 102, and does not have, for example, a portion that protrudes upward. Therefore, even if a foreign object is placed on the cover main body 102 due to wind from traveling or submersion while the vehicle 500 is traveling, the foreign object is pushed by wind force, aerodynamic force, or inertial force from the front, and falls down along the downwardly inclined portion 124. As a result, foreign object that has been placed on the cover main body 102 due to wind from traveling or submersion can be efficiently expelled.

[0043] It is also possible to reduce the amount of foreign matter that is placed on the cover body 102 due to wind caused by running or flooding. Since the downwardly inclined portion 124 is provided, the rigidity of the rear end of the vehicle floor undercover 100 can be improved.

[0044] Since the cover body 102 further has the upwardly inclined portion 122, the rigidity of the rear end of the vehicle floor undercover 100 can be further improved.

[0045] Because the front end 122b1 of the upward inclined portion 122 is located lower than the rear end 124b1 of the downward inclined portion 124, it is possible to prevent the flow of air that has passed below the front end 122b1 of the upward inclined portion 122 from being blocked by the downward inclined portion 124. If the front end 122b1 of the upward inclined portion 122 were located higher than the rear end 124b1 of the downward inclined portion 124, the air that has passed below the front end 122b1 of the upward inclined portion 122 would hit the downward inclined portion 124, and the flow of the air would be blocked.

[0046] Because rear end portion 126 is located at the same height as the center in the front-to-rear direction of undersurface 122b of upwardly inclined portion 122, it is possible to straighten the airflow that flows rearward from the undersurface of upwardly inclined portion 122 along groove portion 123, thereby reducing air resistance. Furthermore, because rear end portion 126 is further provided, the rigidity of the rear end of vehicle floor undercover 100 can be further improved.

[0047] Because rear end portion 126 has a shape that convex rearward in plan view, the length of the rear edge of the vehicle floor undercover can be set longer than when rear end portion 126 is formed in a straight line in the vehicle width direction in plan view. This makes it possible to ensure a longer area for foreign objects to be ejected, improving the efficiency of removing foreign objects.

[0048] Since the vehicle floor undercover 100 has the fixing portion 140 that protrudes upward, the position of the fixing portion 140 can be easily identified when assembling the vehicle floor undercover 100 to the underside of the vehicle floor, improving workability.

[0049] Since the vehicle floor undercover 100 has the fixing portion 140 that protrudes upward, the rigidity of the groove portion 123 can be improved and deflection in the direction perpendicular to the surface can be reduced.

[0050] Furthermore, the rigidity of the rear end of the vehicle floor undercover 100 is improved by the fixing portion 140, the downward inclined portion 124, the upward inclined portion 122, and the groove portion 123, so that foreign matter is less likely to accumulate and vibration can be suppressed.

[0051] While the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to these examples. It is clear that those skilled in the art can conceive of various modifications and alterations within the scope of the claims, and it is understood that these modifications and alterations also fall within the technical scope of the present invention.

[0052] Furthermore, the present invention can be practiced by freely combining inventions described in claims and examples, regardless of the dependent relationships of the claims. [Industrial Applicability]
