Description

  The present invention relates to a fender cover that is attached so as to cover a fender end and its lower part in an engine room.

  Like the vehicle shown in FIGS. 10 and 11, the engine room 52 covered with the hood hood 51 is complicated because the joint portions of various members are exposed or the devices are arranged. . Conventionally, since the engine room 52 is normally covered with the hood hood 51 and is not visible from the outside, the complexity in the engine room 52 has not been so much a problem. However, since the inside of the engine room 52 may be inspected by opening the hood hood 51, it is not preferable to give a complicated impression to the vehicle user or the like.

  In particular, as shown in FIG. 12, the vehicle fender 53 (particularly the front fender) 53 has a fender end portion 55 disposed in the engine compartment and a fender from the vehicle body structural member 57 positioned below the fender end portion 55. It is attached so that the end 55 is located at a distance. For this reason, there is a gap S between the fender end 55 and the vehicle body component 57 located below the fender end 55, making it unsightly. The clearance S between the fender end 55 and the vehicle body component 57 allows the fender 53 to be deformed into the engine compartment when an impact is applied to the vicinity of the top of the fender 53 from an obliquely upward front as shown in FIG. And for the reason of absorbing a part of the impact by the deformation.

  In order to eliminate the unsightly appearance caused by the gap S existing between the fender end 55 and the vehicle body component member 57 positioned below the fender end 55, the fender end 55 and its lower part are shown at a portion indicated by a chain line 61 in FIG. It is conceivable to provide a fender cover covering the front and rear sides in the engine room 51. However, when the fender cover is provided, the presence of the fender cover covering the fender end 55 when the impact is applied from the upper oblique front near the boundary of the bonnet hood 51 with the fender 53 causes the hood hood 51 to Deformation may be hindered and impact load may increase. In particular, in order to effectively cover the gap S between the fender end 55 and the vehicle body constituting member 57 below the fender end 55, it is necessary that the fender cover also covers the upper surface of the fender end 55. Since a part of the fender cover is positioned above the fender end portion 55, the portion of the fender cover positioned above the fender end portion 55 at the time of impact is likely to increase the impact load.

It consists of an elongate molded product along the front-back direction in the room 52. As an example of the dimensions of the fender cover 10, a case where the fender cover 10 has a width of 5 cm, a height of 6 cm, and a length of 120 cm is shown.

  The material of the fender cover 10 is an appropriate plastic (including rubber), and a thermoplastic elastomer (TPE) is particularly preferable. Since the thermoplastic elastomer has rubber elasticity, there is an advantage that it is not easily damaged by deformation when an impact is applied. Thermoplastic elastomers include olefin (TPO), styrene (SBC), vinyl chloride (TPVC), urethane (TPU), polyamide (TAPE), butadiene (RB), and the like. In addition, the material of the fender cover 10 of this embodiment consists of an olefin type thermoplastic elastomer.

  The cross-sectional shape of the fender cover 10 constituted by the upper surface portion 11 and the side surface portion 21 is a substantially “f” shape of katakana in the present embodiment, and the fender end portion 55 is formed by the upper surface portion 11 and the side surface portion 21. And the bottom can be covered.

A locking protrusion 42 formed on the lower surface of the packing 41 is inserted and locked into the packing mounting hole 12. As shown in FIG. 6, the packing 41 is in pressure contact with the inner surface of the hood hood 51 when the hood hood 51 of the vehicle is closed, and seals between the side of the hood hood 51 and the fender cover 10. is there.

  Further, mounting seats 15 are formed on the lower surface 13 of the upper surface portion 11 at predetermined intervals along the length direction. The attachment seat 15 is for attaching the upper surface portion 11 to the upper surface 56 of the fender end portion 55, and is formed to be inclined forward of the fender cover.

  The mounting seat 15 is a mounting surface formed substantially parallel to the upper surface 11 on a wall 16 formed to be inclined from the lower surface 13 of the upper surface 11 toward the front of the fender cover and a lower end 16c of the wall 16. 18 and. In the illustrated example, the wall portion 16 includes a front wall portion 16a and a rear wall portion 16b that are formed in parallel in the front-rear direction of the fender cover with a predetermined distance therebetween. The front wall portion 16a and the rear wall portion 16b are respectively formed in the width direction W (shown in FIGS. 2 and 3) of the upper surface portion 11, and are substantially trapezoidal wall surfaces in the illustrated example. The wall portion 16 is inclined forward at an inclination angle θ, and the lower ends 16c and 16c of the both wall portions are located in front of the fender with respect to the roots 16d and 16d. Since the wall portion 16 is inclined forward, the wall portion 16 is easily bent backward (falling down) when an impact is applied to the upper surface portion 11 from diagonally forward and upward. The increase can be suppressed. The inclination angle θ of the wall portion 16 is preferably an angle at which the wall portion 16 is easily bent backward with respect to an impact when a pedestrian jumped up to the vehicle collides with the fender, specifically 55 to 75. ° is preferred.

  At the base of the mounting seat 15, that is, in the illustrated example, the base 16 d of the wall 16 is formed with an easily bent portion 17 that is thinner than the other portions. The bendable portion 17 makes it easier for the wall portion 16 to bend backward (easily falls down) when an impact is applied to the upper surface portion 11 from diagonally forward and upward, and it is possible to more reliably suppress an increase in impact load. it can. The thin easy-to-bend portion 17 may be a V-shaped groove or a cut in addition to the illustrated concave shape. The thickness of the thin bendable portion 17 and the thickness of the other portion of the wall portion 16 are appropriately determined. As an example, the thickness of the thin bendable portion 17 is 1.0 mm, and the thickness of the other portion is 2.0 mm. List the cases.

  As shown in FIG. 5, the mounting surface 18 has a flat plate shape. In the illustrated example, the front wall portion 16a and the rear wall portion are disposed between the front wall portion 16a and lower ends 16c of the rear wall portion 16b. 16 and a series. A mounting hole 19 is formed in the mounting surface 18. The attachment hole 19 is used for attaching the upper surface portion 11 to the fender end portion 55 with the fixing component K, and an opening portion 19a for inserting the fixing component K into the attachment hole 19 is a side surface portion 21. It is formed on the opposite side. The fixing part K is not limited to the clip having the structure shown in the figure, and may be another clip, bolt, or the like. The fender end 55 is formed with a fixing component insertion hole 59 at a position corresponding to the mounting hole 19, and the fixing component K inserted and held in the mounting hole 19 is inserted into the fixing component insertion hole 59. By inserting, the upper surface portion 11 of the fender cover 10 is attached to the fender end portion 55 as shown in FIGS. 5 and 6.

  Further, as shown in FIG. 3, the mounting seat portion 15 shown in the figure has the wall portion 16 and the mounting surface 18 joined to the inner surface 22 of the side surface portion 21 on one side in the width direction. It may be in contact with the inner surface 22 without being joined, or may be separated. The height T of the mounting seat 18 is determined in consideration of the distance between the fender end 55 in the engine room 52 and the inner surface of the hood hood 51. As an example, a case where the height T is 10 mm is given.

  The side surface portion 21 is formed in series with the upper surface portion 11. In the illustrated example, the side surface portion 21 faces downward from one side in the width direction of the fender cover 10, that is, from the edge facing the center in the vehicle width direction in the engine room. Is formed. Furthermore, the illustrated side surface portion 21 has a curved shape in which the upper and lower intermediate portions swell toward the center in the vehicle width direction. The shape and height of the side surface portion 21 is such that at least the gap S between the fender end portion 55 and the component member 57 below the fender end portion 55 can be covered, and the fender end portion of the vehicle to which the fender cover 10 is attached. And it is determined according to the constituent members below.

  Fixing pieces 23 are formed at predetermined intervals along the length direction of the fender cover 10 at the lower end of the side portion 21. The fixing piece 23 is a portion fixed to a vehicle body member (not shown) positioned below the fender end portion 55 in the engine room 52, and is a hole for inserting a fixing component such as a clip or a bolt. 24 is formed. By fixing the fixing piece 23 to a member in the engine room 52, it is possible to prevent the generation of noise caused by the side surface portion 21 of the fender cover 10 vibrating and colliding with other members during vehicle running or the like. . Note that, depending on the state in the engine room 52, there may be cases where abnormal noise can be prevented without fixing the fixing piece 23 to a member in the engine room 52. Therefore, the fixing piece 23 is not necessarily provided for the fender cover 10. It is not required and may be omitted.

  As shown in FIGS. 6 and 7, the fender cover 10 has the mounting seat 15 disposed on the fender end 55 in the engine room 52 with the packing 41 attached to the upper surface portion 11, and the attachment It is attached to the fender end 55 by a fixing part K such as a clip inserted through the attachment hole 19 of the surface 18. The fixing piece 23 at the lower end of the side portion 21 is fixed to a member in the engine room 52 by a fixing component such as a clip. When the fender cover 10 is attached, the upper portion of the fender end portion 55 is covered with the upper surface portion 11 of the fender cover 10, and the side portion is between the fender end portion 55 and the structural member 57 of the vehicle body located below the fender end portion 55. 21, the engine room 52 is covered from the center in the vehicle width direction, and the beauty of the vicinity of the fender end 55 is improved.

  When an impact is applied to the fender cover 10 in the vicinity of the fender boundary of the hood hood corresponding to the upper part of the fender end portion 55 of the vehicle to which the fender cover 10 is attached, as shown in FIG. As shown in FIG. 8, the mounting seat 15 is bent backward (falls down), and an increase in impact load can be suppressed. At that time, since the mounting seat 15 is formed to be inclined forward from the lower surface of the upper surface portion 11, it is easily bent and deformed rearward due to an impact from obliquely upward on the front. Moreover, since the thin easy-to-bend portion 17 is formed at the base of the mounting seat portion 15, the mounting seat portion 15 is easily bent at the base by an impact, and an increase in impact load can be suppressed more reliably. .

  Note that the rear end 10a of the fender cover moves rearward in the engine compartment as shown in FIG. A gap d is provided between the rear end 10a of the fender cover and the rear member 63 of the fender cover so that the rear end 10a of the fender cover does not collide with the rear member 63 of the fender cover in the engine room during movement. It is preferable not to prevent the backward bending deformation of the portion 15.

  The gap d is equal to or greater than the rearward movement amount d1 of the fender cover 10 due to the rearward bending deformation of the mounting seat portion 15. Note that the maximum value d1max of the rearward movement amount d1 of the fender cover 10, that is, the rearward movement amount when the front wall portion 16a overlaps the mounting surface 18 without interfering with the head of the fixed component K is the wall [D1max = L−Lcosθ] or [d1max = (1−cosθ) × T / sinθ, where L is the length of the portion 16, T is the height of the mounting seat portion 15, and θ is the inclination angle of the wall portion 16. Therefore, if the fender cover 10 is attached so that the value of d is equal to or greater than d1max, the rear end 10a of the fender cover and the fender cover rear member 63 are attached by impact during impact. The backward bending inhibition of the seat portion 15 can be prevented more reliably, and an increase in impact load can be efficiently suppressed.

  In the above-described embodiment, the wall portion 16 of the mounting seat portion 15 is configured by the front wall portion 16a and the rear wall portion 16b, but is configured by only one of the front wall portion 16a and the rear wall portion 16b. The mounting surface 18 may be provided at the lower end of one wall portion.
