Description

  The present invention relates to a vehicle outer plate support structure for supporting a vehicle outer plate panel with a vehicle body skeleton member.

  An outer panel such as a roof panel of a vehicle is supported by a side rail, a roof panel reinforcement, or the like which is a vehicle body skeleton member, and various techniques have been proposed for the support structure. In recent years, a lightweight material such as an aluminum material is sometimes used for the roof panel in order to reduce the weight. In that case, the coefficient of thermal expansion increases. However, if the difference in coefficient of thermal expansion between the roof panel and the vehicle body skeleton member increases, in the manufacturing process under a high temperature environment (for example, paint drying baking process), the thermal expansion of the roof panel The distance between the roof panel and the body frame member is increased. When the roof panel is subsequently cooled, the roof panel attempts to return to its original state from the expanded state, but is repelled by the mastic adhesive applied to the body frame member and returns to the set original position. And the outer panel may be distorted.

  Therefore, in Patent Document 1, a clearance is formed on the joint surface between the roof bow and the roof panel to secure the thickness of the mastic adhesive and reduce the elastic modulus. Thus, by lowering the elastic modulus of the mastic adhesive, it becomes easier for the mastic adhesive to elastically deform, and in the manufacturing process, it is possible to suppress thermal distortion that the roof panel is likely to cause by cooling after thermal expansion. Become. However, when the elastic modulus of the mastic adhesive is simply lowered, the function of suppressing the vibration of the roof panel and the tension rigidity of the roof panel are lowered.

  In the vehicle outer plate support structure according to the first aspect of the present invention, the elastic member is disposed between the outer plate panel and the vehicle body skeleton member. The elastic member has a first elastic part and a second elastic part. The first elastic portion abuts on the outer plate panel and is elastically deformed by receiving a load from the outer plate panel. The second elastic portion is disposed at a position farther from the outer plate panel than the first elastic portion before elastic deformation, and receives a load from the outer plate panel together with the first elastic portion. Thus, by having the 1st elastic part and the 2nd elastic part, after the 1st elastic part elastically deforms and the space | interval of an outer board panel and a vehicle body frame member narrows, a 2nd elastic part is from an outer board panel. Take the load. Therefore, the elastic modulus of the elastic member changes before and after the second elastic portion receives a load. That is, before the second elastic part receives a load, only the first elastic part comes into contact with the outer panel to suppress the vibration of the outer panel, and the low elastic modulus is maintained to suppress the distortion of the outer panel.

It is characterized by being.

  According to the vehicle outer plate support structure according to claim 3, when the outer plate panel is disposed at the outer plate panel position at normal temperature, the first elastic portion and the second elastic portion receive a high load from the outer plate panel. Tension rigidity can be ensured by an elastic modulus. When the outer panel is arranged outside the vehicle panel position at room temperature, only the first elastic part contacts the outer panel and the second elastic part is not in contact with the outer panel and the first elastic part. Thus, the vibration of the outer panel can be suppressed while the low elastic modulus is maintained and the distortion of the outer panel is suppressed. Here, the outer panel position at normal temperature refers to the arrangement position of the outer panel in a state where an external force is not applied at normal temperature.

  According to a fourth aspect of the present invention, the vehicle outer plate support structure includes an engaging member that is provided on the elastic member and is engaged with the vehicle body skeleton member.

  According to the vehicle outer plate support structure of the fourth aspect, by engaging the engaging member with the vehicle body skeleton member, the elastic member can be easily attached to the vehicle body skeleton member and between the outer plate panel and the vehicle body skeleton member. Can be arranged.

[First Embodiment]
Hereinafter, embodiments of a vehicle outer plate support structure according to the present invention will be described with reference to the drawings. In the figure, an arrow UP indicates the vehicle upper side, an arrow OUT indicates the vehicle width direction outer side, and an arrow FR indicates the vehicle front side.

  FIG. 1 is a perspective view of an upper portion of a vehicle to which the vehicle outer plate support structure according to the present embodiment is applied. 2 shows a cross-sectional view taken along line AA of FIG. As shown in FIG. 1, the vehicle roof 10 includes a roof panel 30 covering the cabin and roof side rails 12 provided on both sides in the vehicle width direction. A pair of left and right roof side rails 12 are disposed along the vehicle front-rear direction. Between the pair of roof side rails 12, a front header 20, a rear header 22, and a roof reinforcement 24 formed of a metal such as a steel plate are bridged along the vehicle width direction. The front header 20 is disposed at the front end portion in the vehicle front-rear direction, the rear header 22 is disposed at the rear end portion in the vehicle front-rear direction, and the roof reinforcement 24 is disposed between the front header 20 and the rear header 22.

  As shown in FIG. 2, the roof reinforcement 24 is substantially hat-shaped in cross section and includes a main body portion 24A and a flange portion 24B. The main body 24A has a substantially U-shaped cross section, and is disposed along the vehicle width direction with the U-shaped open side facing the roof panel 30. A convex portion 24C that is convex upward is formed at the center in the width direction of the main body portion 24A. The flange portion 24B extends outward from both ends of the U-shape of the main body portion 24A. The flange portion 24B is disposed to face the roof panel 30. A plurality of long holes 24H that are long in the vehicle width direction are formed in the flange portion 24B. An engaging portion 46C of an engaging member 46 described later is engaged with the long hole 24H.

  The roof panel 30 is a rectangular panel that is curved so as to bulge upward from the vehicle width direction both ends to the center, and covers the cabin from the vehicle upper side. The roof panel 30 is formed of a lightweight material (made of aluminum). As shown in FIG. 3C, the roof panel 30 is disposed at a normal position P1 where the distance from the flange portion 24B of the roof reinforcement 24 is S1 at room temperature. On the other hand, for example, under a high temperature in a painting process or the like, as shown in FIG. 3B, the gap between the flange portion 24B and the flange portion 24B is disposed at the expansion position P2 where S2 is larger than S1.

An elastic member 40 is disposed between the roof panel 30 and the roof reinforcement 24. The elastic member 40 is formed of a material having elasticity such as rubber. A plurality of elastic members 40 are provided in the vehicle width direction, and are disposed on the flange portion 24 </ b> B of the roof reinforcement 24.

As shown in FIG. 3A, the elastic member 40 has a substantially triangular cross section before elastic deformation, the apex side of the triangle is disposed on the roof panel 30 side, and the bottom side is disposed on the flange portion 24B side. Has been. The elastic member 40 includes a first elastic part 42 and a second elastic part 44. The first elastic portion 42 has a mountain shape that forms two sides sandwiching the apex of the triangle with a predetermined thickness before elastic deformation. The elastic modulus of the first elastic portion 42 is set to K1. The second elastic portion 44 has a base portion 44A that forms a triangular base with a predetermined thickness, and an inner convex portion 44B that gently protrudes from both ends of the base portion 44A toward the apex side. The elastic modulus K2 of the second elastic portion 44 is set to be larger than the elastic modulus K1 of the first elastic portion 42. The bottom portion 44A and the inner convex portion 44B are separated from each other, and a space R1 is formed.

As shown in FIG. 3C, when the roof panel 30 is disposed at the normal position P1, the elastic member 40 has the first elastic portion 42 pushed by the roof panel 30 to the second elastic portion 44. It is compressively deformed so that it abuts. Further, as shown in FIG. 3B, when the roof panel 30 is disposed on the vehicle outer side (upper side) than the normal position P1 due to thermal expansion or the like (hereinafter, the position of the roof panel 30 is “expanded”). The first elastic portion 42 and the second elastic portion 44 are separated from each other, and the first elastic portion 42 is pressed by the roof panel 30 and compressed while the first elastic portion 42 and the roof panel 30 are in contact with each other. It is deformed. The distance (S2-S1) between the expansion position P2 of the roof panel 30 and the normal position P1 is S0. Further, ST is a stroke from the normal position P1 of the roof panel 30 due to vibration input. On the roof reinforcement 24, the roof panel 30 is supported on the elastic member 40 attached to the flange portion 24B.

In the present embodiment, as described above, the first elastic portion 42 is set to be in contact with the second elastic portion 44 in a state where the roof panel 30 is disposed at the normal position P1. The position at which the first elastic portion 42 abuts on the second elastic portion 44 may be shifted due to a dimensional error of this, a change in the performance of rubber over time, or the like. In the present embodiment, even when the first elastic portion 42 is brought into contact with the second elastic portion 44 at a position slightly deviated as described above, the first state in which the roof panel 30 is substantially disposed at the normal position P1. The elastic portion 42 is included in contact with the second elastic portion 44.

FIG. 4 shows a graph showing the relationship between the load and the stroke caused by compressive deformation (corresponding to the amount of movement of the roof panel 30) for the elastic member 40 described above. When the stroke is 0 to S0, the load changes from 0 to F0, and the elastic modulus of the elastic member 40 is the elastic modulus K1 of the first elastic portion 42 alone. If the first elastic part 42 contacts the second elastic part 44 when the stroke is S0 and the stroke exceeds S0, the elastic modulus of the elastic member 40 is the elastic modulus of the first elastic part 42 and the second elastic part 44. Is set to increase to the elastic modulus K3.

The load F0 is set to a value that does not cause distortion in the roof panel 30. That is, the roof panel 30 is set so as not to be distorted even if the pressing force from the elastic member 40 acts on the roof panel 30 disposed at the normal position P1. When the load applied to the roof panel 30 due to vibration input exceeds F0, the elastic modulus of the elastic member 40 increases and becomes K3. Thereby, the load F1 with respect to the stroke ST can be increased.

An engaging member 46 is provided on the side opposite to the inner convex portion 44B of the bottom side portion 44A. The engaging member 46 has a fixed portion 46A and an engaging plate 46B along the bottom side portion 44A. The fixed portion 46A is plate-shaped, and one side of the plate surface is joined to the base portion 44A. The engagement plate 46B is bent so as to be folded back from one end side of the fixed portion 46A, and is formed integrally with the fixed portion 46A. The engaging plate 46B is formed with an engaging portion 46C that protrudes toward the fixed portion 46A. The engaging portion 46C is engaged with the long hole 24H of the flange portion 24B, and the flange portion 24B is sandwiched between the fixing portion 46A and the sandwiching plate 46B. The engaging member 46 can be formed of resin, metal, or the like.

Next, the effect of the vehicle outer plate support structure of this embodiment is demonstrated.

Since the elastic member 40 of this embodiment does not require a curing treatment at a high temperature like a mastic adhesive, the elastic member 40 can be assembled before or after the painting process. When assembled before the painting process, the engaging member 46 is attached to the flange portion 24B of the roof reinforcement 24 so that the elastic member 40 is disposed on the upper side. For attachment, the fixing portion 46A and the clamping plate 46B are attached from the end side of the flange portion 24B so as to sandwich the flange portion 24B, and the engaging portion 46C is engaged with the elongated hole 24H. When the roof panel 30 is assembled and disposed at the normal position P <b> 1, the first elastic portion 42 of the elastic member 40 is compressed and deformed and comes into contact with the second elastic portion 44.

In this state, when transported into the coating furnace in the coating process, the roof panel 30 which is thermally expanded due to a high temperature and is formed of aluminum having a relatively small thickness and a high thermal expansion coefficient is disposed at the expansion position P2. At this time, the first elastic portion 42 is deformed by the restoring force following the movement of the roof panel 30, and the amount of compressive deformation is reduced.

When the painting process is completed and the temperature returns to room temperature, the roof panel 30 contracts from the expanded state and returns to the normal position P1. At this time, the first elastic portion 42 is compressed and deformed again following the movement of the roof panel 30, and supports the roof panel 30 while being in contact with the second elastic portion 44.

In the vehicle outer plate support structure of the present embodiment, the roof panel 30 is supported by the elastic force of only the first elastic portion 42 having the elastic modulus K1 when moving from the expansion position P2 to the normal position P1. Therefore, the roof panel 30 can be easily moved from the expansion position P2 to the normal position P1, and distortion can be prevented or suppressed.

Further, since the roof panel 30 is used in a state where it is disposed at the normal position P1, the elastic modulus of the elastic member 40 is an elastic modulus K3 that combines the first elastic portion 42 and the second elastic portion 44. Therefore, when vibration is input or an external force is applied, it can be received with a high elastic modulus, tension rigidity can be ensured, and the damping effect can be improved.

In the present embodiment, the elastic modulus K2 of the second elastic portion 44 is set to be larger than the elastic modulus K1 of the first elastic portion 42, but the elastic modulus K2 is not necessarily set to be larger than K1, and the elastic modulus Even if K2 and K1 are the same, the elastic modulus K2 may be set smaller than K1. As in this embodiment, by setting the elastic modulus K2 to be larger than K1, the elastic modulus after the second elastic portion 44 receives a load can be increased, and higher tension rigidity can be ensured. In addition, the vibration control effect can be improved.

As a method for setting the elastic modulus K2 of the second elastic portion 44 to be larger than the elastic modulus K1 of the first elastic portion 42, the first elastic portion 42 is made of foamed rubber, or the first elastic portion 42 and the second elastic portion 44. May be used as foaming rubber so that the foaming rate of the first elastic part 42 is higher than the foaming rate of the second elastic part 44.

Further, in the present embodiment, the first elastic portion 42 is set to contact the second elastic portion 44 at the position where the roof panel 30 is disposed at the normal position P1, but the first elastic portion 42 is the second elastic portion 42. It is not always necessary to set the position in contact with the elastic portion 44 in this way. If the abutting is performed on the vehicle inner side than the normal position P1, the distortion of the roof panel 30 can be prevented. In addition, if the first elastic portion 42 is in contact with the second elastic portion 44 within the range of the stroke of the roof panel 30 with respect to normal vibration input, the tension rigidity of the roof panel 30 can be secured and the control can be suppressed. The vibration effect can be improved.

Further, the elastic member 40 of the present embodiment does not need to be used at all positions for supporting the roof panel 30, but is used only for a portion where distortion is likely to occur, and a mastic adhesive is used for other portions. Also good.

In this embodiment, the elastic member 40 is provided with the engaging member 46, and the elastic member 40 is attached to the roof reinforcement 24 by attaching the engaging member 46 to the flange portion 24B. However, the engaging member 46 is not necessarily provided. There is no. For example, the elastic member 40 may be fixed to the flange portion 24B with an adhesive. By attaching via the engaging member 46 as in this embodiment, the elastic member 40 can be easily attached.

(Modification 1 of elastic member)
Next, the modification 1 of the elastic member 40 of this embodiment is demonstrated. As shown in FIG. 5A, the elastic member 50 according to the modified example 1 has a substantially triangular cross section like the elastic member 40, the apex side of the triangle is disposed on the roof panel 30 side, and the bottom side is a flange. It is arranged on the part 24B side. The elastic member 50 includes a first elastic part 52 and a second elastic part 54. The first elastic part 52 has the same configuration as the first elastic part 42. The second elastic portion 54 has a base portion 54A having the same configuration as the base portion 44A, and a central convex portion 54B that protrudes from the central portion of the base portion 54A toward the apex side. The elastic modulus K2 of the second elastic portion 54 is set larger than the elastic modulus K1 of the first elastic portion 52.

When the roof panel 30 is disposed at the normal position P <b> 1, the elastic member 50 is compressed and deformed so that the first elastic portion 52 is pushed by the roof panel 30 and comes into contact with the second elastic portion 54. Further, when the roof panel 30 is disposed at the expansion position P2 due to thermal expansion or the like, the first elastic portion 52 and the second elastic portion 54 are separated from each other, and the first elastic portion 52 and the roof panel 30 are in contact with each other. 1 The elastic part 52 is pressed by the roof panel 30 and is compressed and deformed. Even if the elastic member 50 having the configuration is used, the same effect as that of the elastic member 40 can be obtained.

(Modification 2 of elastic member)
Next, Modification Example 2 of the elastic member 40 of the present embodiment will be described. As shown in FIG. 5B, the elastic member 60 according to the modified example 2 includes the first elastic portion 62 having the same configuration as the first elastic portion 42 of the elastic member 40 and the bottom side of the second elastic portion 44. It has the base part 64A and the inner side convex part 64B of the structure similar to the part 44A and the inner side convex part 44B, and also has the center convex part 64C. The central convex portion 64C is provided so as to connect the central portion of the bottom side portion 64A and the central portion of the inner convex portion 64B.

Thus, by providing the central convex portion 64 between the bottom portion 64A of the second elastic portion 64 and the inner convex portion 64B, the elastic modulus K2 of the second elastic portion 64 can be easily increased. It can be set larger than the elastic modulus K1. Even when the elastic member 60 having the configuration is used, the same effect as that of the elastic member 40 can be obtained.
