Description

  The present invention relates to a structure of a mating portion of an exterior component, and particularly relates to a structure of a mating portion between a headlamp and an edge portion of a fender around the headlamp.

  In general, a headlamp of an automobile is provided with an ear on the periphery of the headlamp, and the ear is attached to a fender edge with a screw, whereby the headlamp is fixed to the front of the vehicle body. In such a headlamp, when an obstacle collides with the headlamp, the ear part is broken by the impact force and the headlamp is displaced to the inside of the vehicle body (mainly downward), thereby reducing the impact force to the obstacle. I try to relax.

  On the other hand, when the headlamp is attached to the fender, a gap is formed between the surface edge of the headlamp and the fender edge, but if such a gap is too wide and conspicuous, the appearance quality of the vehicle will deteriorate. To do.

  In order to prevent this, at the boundary portion between the headlamp and the fender, the peripheral edge of the headlamp and the edge of the fender are wrapped in the vertical direction, and the gap between the peripheral edge of the headlamp and the fender edge is outside. A headlamp mounting structure that is difficult to see is known. In this case, if the wrap amount is not sufficient, the gap between the peripheral edge of the surface of the headlamp and the fender edge can be seen from the outside, so that the appearance quality of the vehicle cannot be improved.

Therefore, a headlamp mounting structure has been proposed in which the peripheral edge of the headlamp surface and the fender edge are wrapped in the vertical direction, and the gap between the peripheral edge of the headlamp and the fender edge is narrowed (for example, , See Patent Document 1).
JP-A-2005-75337

  However, in the above conventional technique, when the headlamp is displaced to the inside of the vehicle body by colliding with an obstacle, the wrapped portion of the peripheral edge of the headlamp surface is caught on the fender edge, and the headlamp is moved to the inside of the vehicle body. There is a possibility that the displacement is hindered and the impact force on the obstacle cannot be sufficiently reduced.

  In addition, since the gap between the headlamp edge and the fender edge is narrowed, the headlamp edge rubs against the fender edge when the headlamp is displaced to the inside of the vehicle body. May peel off and rust may be generated at the fender edge.

  An object of the present invention is to alleviate the impact force to an obstacle when it collides with an exterior part such as a headlamp, and when the headlamp etc. is displaced to the inside of the vehicle body to reduce the impact force, It is an object of the present invention to provide a structure of a mating portion of an exterior component that can prevent a headlamp or the like from rubbing against an edge portion of a fender or the like that is an exterior component disposed on the exterior.

  In order to solve the above-described problem, the present invention has a structure of a mating portion of two exterior components at the front of the vehicle, and projects the mating portion of one exterior component upward with respect to the mating portion of the other exterior component, A convex portion is formed on the mating portion of the one exterior component so as to wrap with respect to the mating portion of the other exterior component in a top view of the vehicle, and the mating portion of the one exterior component and the other are provided below the convex portion. A feature is that the fitting parts of the exterior parts are provided apart from each other.

  According to the above configuration, the convex portion that wraps in the vehicle top view with respect to the mating portion of the other exterior component (for example, the fender around the headlamp) is formed in the mating portion of one exterior component (for example, the headlamp). Therefore, when an obstacle collides with one exterior part, one exterior part is likely to be displaced to the inside of the vehicle body until the convex part hits the other mating part, and as a result, the impact force on the obstacle is sufficiently mitigated can do.

  Also, since the mating part of one exterior part and the mating part of the other exterior part are provided apart from each other, when one exterior part is displaced inward of the vehicle body, the mating part of one exterior part is the other exterior part. It is possible to prevent the parts from being rubbed against each other.

  According to the present invention, when an obstacle collides with one exterior part (for example, a headlamp), the one exterior part is easily displaced toward the inside of the vehicle body, and the impact force on the obstacle can be sufficiently reduced. .

  In addition, since the mating portion of one exterior component and the mating portion of the other exterior component (for example, a fender around the headlamp) are provided apart from each other, one exterior component is moved to the inside of the vehicle body to reduce impact force. When displaced, it is possible to prevent the mating portion of one exterior component from rubbing against the mating portion of the other exterior component. As a result, when the mating portion of the other exterior part is painted, it is possible to avoid peeling of the coating.

  Furthermore, since the convex part which wraps in the vehicle top view with respect to the mating part of the other exterior part is formed in the mating part of one exterior part, the mating part of one exterior part and the mating part of the other exterior part The gap between the two is concealed by the convex portion and is not conspicuous from the outside.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 and 2 show the headlamp and the surrounding structure of the headlamp, FIG. 1 is a right side view thereof, and FIG. 2 is a perspective view taken along the line SA-SA in FIG. 1 and 2 show the configuration on the right side of the vehicle. The configuration on the left side of the vehicle is symmetrical to the configuration of FIGS. 1 and 2 with respect to the center of the vehicle.

  As shown in FIG. 1, a headlamp 2 is provided at the front end of a fender (front fender) 1. That is, the fender 1 has a notch 3 formed from the front upper surface to the front side surface, and the headlamp 2 is embedded in the notch 3. As shown in FIG. 2, the edge of the fender 1 (hereinafter referred to as the fender edge 1A) is arranged in the vicinity of the right surface (left side in FIG. 2) of the surface portion periphery 2A of the surface portion periphery of the headlamp 2. Has been. Here, the headlamp 2 constitutes one exterior component, the fender 1 constitutes the other exterior component, and the surface portion peripheral edge 2A of the headlamp 2 serves as the mating portion of the one exterior component. The fender edge 1A constitutes a mating portion for the other exterior part.

  As shown in FIG. 3, an elastic member 4 is interposed between the fender edge 1 </ b> A and the surface edge 2 </ b> A of the headlamp 2. The elastic member 4 has a thin belt shape and is formed in a substantially inverted L shape when viewed from above. The elastic member 4 is provided in contact with the right surface portion peripheral edge 2 </ b> A and the rear surface peripheral portion 2 </ b> B of the headlamp 2.

  FIG. 4 is an enlarged view of part A in FIG. As shown in FIG. 4, the peripheral edge 2 </ b> A of the headlamp 2 protrudes above the fender edge 1 </ b> A of the fender 1. And the convex part 5 which protruded to the vehicle width direction outer side is formed in the upper part of the surface part periphery 2A of the headlamp 2. As shown in FIG. In addition, the fender edge 1 </ b> A is bent downward and disposed below the convex portion 5. That is, when viewed from above, the fender edge 1 </ b> A is disposed so as to wrap around the convex portion 5. Let the amount of laps at this time be b. Further, the fender edge 1 </ b> A is disposed with a gap between the head lamp 2 and the surface portion periphery 2 </ b> A, that is, spaced from the surface portion periphery 2 </ b> A.

  Further, as described above, the fender 1 has a fender edge 1A bent downward, and a portion near the fender edge 1A and outside the fender edge 1A in the vehicle width direction is on the upper side. It is bent into a convex shape. And the part bent on this convexly forms the highest position in the fender 1, that is, the uppermost part P. The uppermost portion P is disposed on the outer side in the vehicle width direction from the position of the end portion of the convex portion 5 formed on the headlamp 2. That is, the vertical line L passing through the uppermost portion P is located on the outer side in the vehicle width direction from the end portion of the convex portion 5.

  Although not shown in the drawing, the convex portion 5 is also formed on the upper surface periphery 2B (see FIG. 3) of the headlamp 2, and the fender edge 1A facing the surface periphery 2B is also bent downward. The fender edge 1 </ b> A is disposed below the convex portion 5. Further, the fender edge 1A facing the surface periphery 2B is arranged with a gap between the surface periphery 2B, that is, spaced from the surface periphery 2B.

  Here, as shown in FIG. 4, the protruding amount of the convex portion 5 is called a step width a, and the step width a is determined when the headlamp 2 is designed. Further, the length of the portion bent downward of the fender edge 1A, that is, the length h2 in the vertical direction from the uppermost portion P of the fender 1 to the lower end of the fender edge 1A is also designed when the headlamp 2 is designed. Determined.

  The wrap amount b between the convex portion 5 and the fender edge 1A is preferably small, and is preferably 2 mm or less (0 to 2 mm). If the amount of lap b exceeds 2 mm, even if the obstacle M (see FIG. 6) collides and the headlamp 2 is slightly displaced toward the inside (downward) of the vehicle body, the convex portion 5 is easily caught on the fender edge 1A. This is because the impact force cannot be sufficiently relaxed.

  The elastic member 4 is made of rubber or polypropylene, and its rigidity is set to 0.01 to 2 GPa. Rubber has a stiffness of about 0.01 GPa and polypropylene has a stiffness of about 2 GPa. The elastic member 4 has at least a black surface so that the elastic member 4 does not stand out when viewed from the outside.

  Next, the operation of this embodiment will be described.

  Since the convex portion 5 is formed on the peripheral edge 2A, 2B of the surface portion of the headlamp 2, and the fender edge portion 1A is disposed so as to be wrapped with the convex portion 5 below the convex portion 5, as shown in FIG. When the obstacle M collides with 2, the headlamp 2 is likely to be displaced inward of the vehicle body until the convex portion 5 hits the fender edge 1A. As a result, the impact force on the obstacle M can be sufficiently relaxed. FIG. 6 shows a state in which the obstacle M collides with the headlamp 2 and the headlamp 2 is displaced downward.

  Further, since the surface portion peripheral edges 2A and 2B of the headlamp 2 and the fender edge portion 1A are arranged apart from each other, when the headlamp 2 is displaced inward of the vehicle body, the surface peripheral edges 2A and 2B of the headlamp 2 are It is possible to prevent the surface of the fender edge 1A from being peeled off without rubbing against the fender edge 1A.

  FIG. 5 shows a state in which the elastic member 4 is deformed by the headlamp 2 being displaced downward. At this time, the wrapping amount b between the convex portion 5 and the fender edge portion 1A is smaller than that in the case of FIG.

  As shown in FIG. 7, the elastic member 4 in this embodiment has a rectangular cross section. If the cross section is rectangular, when the obstacle M collides with the headlamp 2, the headlamp 2 is likely to be displaced to the inside of the vehicle body. The elastic member 4 has an upper surface S1 in contact with the convex portion 5 of the headlamp 2, and a side surface S2 on the outer side in the vehicle width direction in contact with the fender edge 1A. When considering a horizontal plane D passing through the intersection line C with the upper surface S1, the side surface S2, the angle θ between the horizontal plane D and the side surface S2 is preferably set to 60 degrees or more. This is because if the angle θ is 60 degrees or more, when the obstacle M collides with the headlamp 2, the headlamp 2 is likely to be displaced to the inside of the vehicle body.

  In the elastic member 4, when the horizontal width of the upper surface S1 is d1 and the height of the side surface S2 is h1, d1≈a (see FIG. 4 for a) is set, and h1 ≧ h2 (refer to FIG. 4 for h2).

  The cross-sectional shape of the elastic member 4 is not limited to a rectangle, but may be a trapezoid as shown in FIG. 8 or a triangle as shown in FIG. Even when the cross section of the elastic member 4 is trapezoidal or triangular, when the obstacle M collides with the headlamp 2, the headlamp 2 is likely to be displaced to the inside of the vehicle body. In the case of FIGS. 8 and 9, the angle θ is 60 degrees or more, d1≈a is set, and h1 ≧ h2 is set.

  Next, the point which set the rigidity of the elastic member 4 to 0.01-2GPa is demonstrated.

  FIG. 10 shows the relationship between the strain of the elastic member 4 and the stress in the elastic member 4 when an external force is applied to the elastic member 4. Here, E1 is such that the lap amount b (see FIG. 4) is reduced when the headlamp 2 is displaced inward of the vehicle body at the time of collision with the obstacle M and the elastic member 4 interferes with the fender edge 1A. The size is set. For example, E1 shown in FIG. 10 shows a case where the elastic member 4 is formed of rubber (stiffness: about 0.01 GPa), the step width a is set to 10 mm, and the lap amount b is set to 0 mm.

  E2 is set to a size that prevents the coating of the fender edge 1A from being peeled off by the contact pressure between the fender edge 1A and the elastic member 4 in a normal state (a state not in a collision). When the headlamp 2 is polycarbonate, the material of the elastic member 4 is selected from polypropylene (stiffness: about 2 GPa) whose rigidity is lower than that of polycarbonate. E <b> 2 indicates a case where polypropylene is selected as the elastic member 4.

  And the area | region R (shaded part of a figure) between E1 and E2 has shown the rigid area | region of the elastic member 4 which can achieve all of relaxation of the impact force to the obstruction M, an external appearance quality improvement, and rust prevention. .

  According to the present embodiment, since the elastic member 4 is installed below the convex portion 5, the gap between the surface portion peripheral edges 2A, 2B of the headlamp 2 and the fender edge portion 1A is filled, and the appearance quality is improved. . Further, when the headlamp 2 is displaced inward of the vehicle body, the fender edge 1A rubs against the elastic member 4, but the object to be rubbed has elasticity, so that the coating of the fender edge 1A is not peeled off. .

  Further, since the uppermost portion P of the fender 1 is disposed on the outer side in the vehicle width direction from the end of the convex portion 5 of the headlamp 2, the convex portion 5 of the headlamp 2 is arranged at the fender edge when the obstacle M collides. It is difficult to be caught by the portion 1A and does not hinder the relaxation of the impact force on the obstacle M.

  Further, since the rigidity of the elastic member 4 is set to 0.01 to 2 GPa, it is possible to prevent the headlamp 2 from being displaced toward the inside of the vehicle body when the obstacle M collides, and to prevent the fender edge 1A from being peeled off. be able to.

  As mentioned above, although the Example of this invention has been explained in full detail with drawing, the said Example is only the illustration of this invention, and this invention is not limited only to the structure of the said Example. Needless to say, changes in design and the like within the scope of the present invention are included in the present invention.

  For example, in the above embodiment, the fender edge 1A is in contact with the side surface S2 of the elastic member 4 in the normal state. However, as shown in FIG. You may make it provide the clearance gap S in this.

  Further, the present invention is not limited to a fender and a headlamp, but can be applied to a relationship between a fender and a bumper, or a bumper and a lamp.
