Abstract

<P>PROBLEM TO BE SOLVED: To avoid a contact between a side edge portion of a hood panel and an upper edge portion of a fender panel without increasing the number of part items, even though the hood panel overruns downward on closing the hood panel. <P>SOLUTION: This seal structure is designed so that a sealing member 9 abutting on a bottom face of a side edge portion 2d of the hood panel 2 is extended on the fender panel 3 in the vehicle longitudinal direction. The side edge portion 2d has a slanting portion which slants outward and downward with the hood panel 2 being closed and the gradient of which becomes larger with its larger size on more backward side. A sealing member 9 relatively decreases a repulsive force of a portion corresponding to the side edge portion of the forward side hood panel 2 where the gradient is smaller, and relatively increases the repulsive force of a portion corresponding to the side edge portion 2d of the backward side hood panel 2 where the gradient is larger, by inserting a pad 10 into the sealing member 9. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a seal structure for a hood for a vehicle, and belongs to a technical field for preventing contact between a side edge portion of a hood panel and an upper edge portion of a fender panel.

Conventionally, a seal member is sometimes provided between a hood panel and a fender panel of a vehicle in order to prevent noise generated in an engine room at the front of the vehicle from flowing out of the vehicle. As a structure using such a seal member, for example, there is one described in Patent Document 1. In this configuration, a sealing member having a hollow portion between the lower portion of the hood panel of the vehicle and the upper portion of the fender panel is provided in the front-rear direction of the vehicle while being fixed to the fender panel. Thus, when the hood panel is closed, the seal member elastically contacts the lower portion of the hood panel and the upper portion of the fender panel, and the gap between the lower portion of the hood panel and the upper portion of the fender panel is closed by the seal member. This prevents the noise generated in the engine room from flowing out of the vehicle.

  By the way, in order to improve the design of a vehicle, the edge part of the both sides of a hood panel may be provided with the inclination part which inclines outward and downward in the state which the hood panel closed. Moreover, the inclination of the inclined portion is not always constant, and may increase, for example, toward the rear side, or conversely, increase toward the front side. In this case, when the hood panel is closed, the size of the linear gap between the lower edge of the inclined portion and the upper edge of the fender panel (the size of the gap viewed in an inclined manner) is the same. Even if it exists, the size of the gap in the vehicle width direction (the size of the gap as seen in plan view) becomes smaller as the gradient of the inclination of the both side edges of the hood panel becomes larger. For this reason, if the hood panel is overrun downward when the hood panel is closed, there is a problem that the inclined portion having a large inclination is in contact with the upper edge portion of the fender panel and is easily damaged.

  In order to cope with this problem, if a new member is provided between the lower part of the hood panel and the upper part of the fender panel for the purpose of avoiding contact, the number of parts increases and the manufacturing cost increases.

  In the vehicular hood seal structure, when the hood panel is closed, the inclined portion of the hood panel and the upper edge of the fender panel come into contact with each other when the hood panel overruns downward. It is an object of the present invention to provide a seal structure that can be avoided without increasing the number.

  In order to solve the above-mentioned problems, the invention according to claim 1 of the present application is directed to a vehicular hood seal in which a seal member that abuts the lower surface of the side edge of the hood panel is extended in the vehicle front-rear direction. The side edge of the hood panel is inclined outward and downward in a state where the hood panel is closed, and has an inclined portion in which the inclination of the inclination increases toward the rear side or the front side. The seal member has a relatively low repulsive force at a portion corresponding to the side edge of the hood panel on the side with the small gradient, and the hood panel on the side with the large gradient when the hood panel is closed. The repulsive force of the portion corresponding to the side edge portion of the hood panel on the side where the gradient is large is relatively high so that the side edge portion of the hood panel does not fall below a predetermined amount from the position where the hood panel is closed. It is characterized in that is.

  Next, the invention according to claim 2 of the present application is the vehicle hood seal structure according to claim 1, wherein the seal member is a cylindrical shape having a hollow portion, and the hood on the side where the gradient is large. The repulsion member having a higher repulsive force than the seal member is inserted into the hollow portion of the portion corresponding to the side edge portion of the panel, so that the repulsion of the portion corresponding to the side edge portion of the hood panel on the side where the gradient is large. It is characterized by relatively high power.

  Next, in the invention according to claim 3 of the present application, in the vehicular hood seal structure according to claim 2, the inclination of the inclined portion is larger toward the rear side, and the rebound member is a seal. A second sealing member that is inserted into a hollow portion on the rear side of the member so that the repelling member protrudes a predetermined amount rearward from a rear end portion of the sealing member, and between the rear portion of the hood panel and the cowl grille. Is extended in the vehicle width direction, corner portions are formed at both ends of the second seal member so as to wrap around the fender panel, and the repulsion member is inserted into an insertion port provided on the front side of the corner portion. The back protrusion part of this is inserted, It is characterized by the above-mentioned.

  According to a fourth aspect of the present invention, in the vehicle hood seal structure according to the third aspect, the corner portion is integrally formed with the second seal member by molding, the corner portion. A side seal portion that is continuously connected to the seal member, and the side seal portion includes a hollow first side seal portion into which a rear protruding portion of the repulsion member provided on the front side is inserted, and a rear side It is comprised from the solid 2nd side seal part provided in the side.

  According to the first aspect of the present invention, the portion of the seal member corresponding to the side edge portion of the hood panel on the side where the inclination of the inclined portion is small (hereinafter sometimes referred to as “first side edge portion” for convenience). The repulsive force of the hood panel (also referred to as “first part”) is relatively low, and the side edge of the hood panel on the side where the inclination of the inclined part is large (also referred to as “second side edge”) The second side of the hood panel when the hood panel is closed by relatively increasing the repulsive force of the portion of the seal member corresponding to (which may also be referred to as “second portion”) Since the edge is not lowered below a predetermined amount from the position where the hood panel is closed, the second side edge of the hood panel is not increased during the closing operation of the hood panel without increasing the number of parts. Contact with the upper edge of the fender panel It is possible to avoid.

  Next, according to the second aspect of the present invention, the repulsion member having a higher repulsive force than the seal member is inserted into the hollow portion of the second portion of the seal member corresponding to the second side edge of the hood panel. Thus, since the repulsive force of the second portion of the seal member is relatively increased, the second side edge of the hood panel and the upper edge of the fender panel can be changed without changing the basic shape of the seal member. Contact can be avoided.

  Next, according to the invention described in claim 3, the inclination of the inclined portion of the hood panel increases toward the rear side, and the repulsion member is inserted into the hollow portion on the rear side of the seal member, A second seal member is provided between the rear portion of the hood panel and the cowl grill when the repulsive member projects rearward by a predetermined amount from the rear end portion of the member, and fenders are provided at both ends of the second seal member. Since the corner portion that wraps around the panel side is formed, and the rearward protruding portion of the repulsion member is inserted into the insertion port provided on the front side of the corner portion, the seal member and the second member are not increased without increasing the number of parts. The seal member can be easily connected to reliably prevent the noise generated in the engine room from flowing out of the vehicle. Furthermore, since the repulsion force of the corner portion of the second seal member as well as the seal member is enhanced by the repulsion member, it is possible to avoid contact between the second side edge portion of the hood panel and the upper edge portion of the fender panel. .

  According to the invention of claim 4, the corner portion is integrally formed with the second seal member by molding, and a side seal portion continuously connected to the seal member is formed at the corner portion, The side seal member is constituted by a hollow first side seal portion into which a rear projecting portion of the repulsion member provided on the front side is inserted, and a solid second side seal portion provided on the rear side. Therefore, the repulsive force on the front side of the side seal portion is increased by the rearward projecting portion of the repulsive member, and the repulsive force on the rear side of the side seal portion is increased by the solid portion. In combination, it is possible to more reliably avoid contact between the second side edge of the hood panel and the upper edge of the fender panel due to the downward overrun when the hood panel is closed.
