  In view of the above fact, the present invention has an object to provide a support structure for a vehicle opening / closing door capable of avoiding the problem of joint peeling between different types of rubber while approaching an ideal load-deformation characteristic. To do.

The vehicle opening / closing door support structure according to the first aspect of the present invention is attached to either the opening / closing door side or the vehicle body skeleton member side, and when the opening / closing door is closed, the opening / closing door, the vehicle body skeleton member, A first cushion rubber which is interposed between the first cushion rubber and elastically deformable in the opening and closing direction of the opening and closing door, and is provided separately from the first cushion rubber and is either the opening door side or the vehicle body skeleton member side The opening and closing door is elastically deformable in the opening and closing direction of the door and has a lower hardness than the first cushion rubber. When the opening and closing door is closed, the opening and closing door contacts the first cushion rubber in series. A second cushion rubber for supporting the door to the vehicle body skeleton member side, and provided on either the other side of the opening / closing door side or the vehicle body skeleton member side, and having higher rigidity than the first cushion rubber and the first cushion rubber. 1 The second cushion rubber abuts on the first cushion rubber, and the load on the door further in the closing direction. Is input, the second cushion rubber is elastically deformed in the closing direction of the open / close door until the contact portion contacts the first cushion rubber, and the contact portion becomes the first cushion rubber. After the contact, the first cushion rubber is elastically deformed in the closing direction of the open / close door while the elastic deformation state of the second cushion rubber is maintained .

  According to the vehicle opening / closing door support structure of the first aspect of the present invention, the first cushion rubber is attached to either the opening / closing door side or the vehicle body skeleton member side, and the second cushion rubber is Since it is provided separately from one cushion rubber and is attached to either the opening / closing door side or the vehicle body skeleton member side, the second cushion rubber and the first cushion rubber are separated or moved by the opening / closing movement of the opening / closing door. Contact. When the open / close door is closed, the second cushion rubber contacts the first cushion rubber in series between the open / close door and the vehicle body frame member to support the open / close door to the vehicle body frame member side.

Here, when the door is closed, the second cushion rubber comes into contact with the first cushion rubber. Since the second cushion rubber has a lower hardness than the first cushion rubber, the second cushion rubber and the first cushion rubber 2 When the load in the closing direction is further input to the opening / closing door in a state where it is in contact with the cushion rubber, first, the second cushion rubber is elastically deformed in the closing direction of the opening / closing door . Further, either the open / close door side or the vehicle body skeleton member side (that is, the side on which the second cushion rubber is provided) has higher rigidity than the first cushion rubber and can contact the first cushion rubber. Since the contact portion is provided, when a load in the closing direction is further input to the opening / closing door, the second cushion rubber is closed in the closing direction of the opening / closing door until the contact portion contacts the first cushion rubber. The first cushion rubber is elastically deformed in the closing direction of the open / close door while the elastic deformation state of the second cushion rubber is maintained after the contact portion is in contact with the first cushion rubber. As a result, the load (deflection reaction force) gradually rises until the abutment portion abuts on the first cushion rubber, and after the abutment portion abuts on the first cushion rubber, the load (deflection reaction force). Rises rapidly. As a result, it is possible to approach the ideal load-deformation characteristics as compared with the case where a single cushion rubber is applied, and the problem of peeling off between different types of rubber does not occur.

According to a second aspect of the present invention, there is provided a support structure for a vehicle opening / closing door according to the first aspect , wherein a concave portion is provided on either the opening / closing door side or the vehicle body skeleton member side. A mounting seat portion to which the second cushion rubber is attached is provided in the concave portion, and the amount of depression to the mounting seat portion in the concave portion is larger than the protruding amount of the second cushion rubber from the mounting seat portion. The outer peripheral part which forms the said concave-shaped part is made into the said contact part, It is characterized by the above-mentioned.

According to the support structure for a vehicle opening / closing door of the present invention described in claim 2 , the amount of depression to the mounting seat in the concave portion is smaller than the amount of protrusion of the second cushion rubber from the mounting seat, and the concave portion. Since the outer peripheral portion forming the contact portion is a contact portion, when a load in the closing direction is further input to the closed door, the outer peripheral portion of the concave portion is not in contact with the first cushion rubber. After the second cushion rubber is elastically deformed in the closing direction of the door and the outer peripheral portion of the concave portion is in contact with the first cushion rubber, that is, the second cushion rubber has a predetermined crushing amount (the mounting seat of the second cushion rubber). After the elastic deformation, the first cushion rubber is in the closing direction of the door while the elastic deformation state of the second cushion rubber is maintained after the elastic deformation. Elastically deforms. As a result, the load (deflection reaction force) gradually rises until the outer peripheral portion of the concave portion comes into contact with the first cushion rubber, and after the outer peripheral portion of the concave portion comes into contact with the first cushion rubber, the load ( Bending reaction force) rises rapidly.

As described above, according to the support structure for a vehicle opening / closing door according to claim 1 of the present invention, characteristics similar to those of the second cushion rubber are obtained until the contact portion contacts the first cushion rubber. After the abutment portion comes into contact with the first cushion rubber, characteristics similar to those of the first cushion rubber can be obtained, so that the ideal load-deformation characteristics should be approached compared to the case where a single cushion rubber is applied. In addition, by adjusting the contact position between the contact portion and the first cushion rubber, it is possible to get closer to the ideal load-deformation characteristics and to separate the first cushion rubber and the second cushion rubber. By attaching separately as a body, it has the outstanding effect that the problem of the peeling-off between different rubber | gum can be avoided.

According to the support structure for a vehicle opening / closing door according to claim 2 , until the outer peripheral portion of the concave portion comes into contact with the first cushion rubber, characteristics similar to those of the second cushion rubber are obtained, and the outer peripheral portion of the concave portion is Since the characteristic approximate to that of the first cushion rubber is obtained after contacting the first cushion rubber, the difference between the amount of protrusion of the second cushion rubber from the mounting seat portion and the amount of depression to the mounting seat portion of the concave portion is obtained. By adjusting, it has an excellent effect of being closer to the ideal load-deformation characteristic.

[First Embodiment]
A first embodiment of a support structure for a vehicle door according to the present invention will be described with reference to the drawings. In the figure, the arrow UP indicates the upward direction of the vehicle, and the arrow FR indicates the forward direction of the vehicle. Further, in the present embodiment, “one of the open / close door side and the vehicle body skeleton member side” is the vehicle body skeleton member side, and “the other side of the open / close door side and the vehicle body skeleton member side” is the open / close door side. Yes.

  As shown in FIG. 1, an apron upper member 12 is disposed along the front-rear direction of the vehicle body at a front portion 10 </ b> A of an automobile (vehicle) body 10, and the apron upper member 12 is disposed in front of the body 10. The parts 10A are respectively attached to the upper portions at both ends in the vehicle width direction. At the front end of the apron upper member 12, a radiator support upper 14 as a vehicle body skeleton member is installed along the vehicle width direction. The vehicle body skeleton member is a member constituting the framework of the vehicle body, and includes, for example, an apron upper member 12, a radiator support upper 14, a pillar, a side member, a rocker, and the like. A front bumper 16 is attached to the front of the radiator support upper 14 along the vehicle width direction.

  Above the apron upper member 12, an engine hood 20 as an open / close door is attached via a hinge (not shown) disposed at the rear end. The engine room 22 can be opened and closed by the engine hood 20. As shown in FIG. 2, the engine hood 20 forms a hood outer panel 24 that constitutes a vehicle outer side portion (upper portion in the closed state) of the engine hood 20 and a vehicle inner portion (lower portion in the closed state) of the engine hood 20. A hood inner panel 25 is provided, and an outer peripheral edge 24A of the hood outer panel 24 and an outer peripheral edge 25A of the hood inner panel 25 are coupled to each other by hemming.

  As shown in FIGS. 1 and 2, a hard cushion rubber 30 as a first cushion rubber is attached to both upper ends of the radiator support upper 14 in the vehicle width direction. In other words, the radiator support upper 14 functions as a support member for the hard cushion rubber 30. As shown in FIG. 2, the hard cushion rubber 30 is used for installation. When the engine hood 20 is closed, the hard cushion rubber 30 is interposed between the engine hood 20 and the radiator support upper 14 and opens and closes the engine hood 20. It can be elastically deformed in the directions of arrows B and C in FIG. The hard cushion rubber 30 is a substantially cylindrical rubber having a high hardness (in this embodiment, the hardness is approximately 80 according to the former JIS A-K6301), and a screw groove is formed on the lower outer peripheral portion at a predetermined pitch. It is formed around the axis of the rubber 30. In the radiator support upper 14 to which the hard cushion rubber 30 is attached, a mounting hole 15 is formed through the upper wall portion 14A, and a lower outer peripheral portion of the hard cushion rubber 30 can be screwed into the mounting hole 15. Yes. The amount of protrusion of the hard cushion rubber 30 from the upper wall portion 14A can be adjusted by the amount of screwing into the radiator support upper 14 at the lower part of the hard cushion rubber 30, thereby making it possible to adjust the installation. ing.

  A soft cushion rubber 32 as a second cushion rubber that is separate from the hard cushion rubber 30 is attached to the engine hood 20 disposed above the hard cushion rubber 30. The soft cushion rubber 32 is smaller in diameter and height than the hard cushion rubber 30, and has a substantially columnar shape that is reduced in diameter from the mounting portion 32A side toward the projecting tip portion 32B (a shape obtained by cutting a conical tip portion). It is said that. The soft cushion rubber 32 can be elastically deformed in the opening / closing direction of the engine hood 20 (arrow B direction and arrow C direction), and has a lower hardness than the hard cushion rubber 30 (in this embodiment, the hardness is old). JIS A-K6301 is around 40), and when the engine hood 20 is closed, the projecting tip 32B is arranged in series with the central portion of the upper surface 30A of the hard cushion rubber 30 so that the engine hood 20 is disposed in a vertical column. It is made to support to 14 side. That is, the soft cushion rubber 32 and the hard cushion rubber 30 function as a support portion for the engine hood 20. In the present embodiment, the soft cushion rubber 32 has a smaller diameter than the hard cushion rubber 30, thereby preventing the hard cushion rubber 30 from sinking into the soft cushion rubber 32 when the engine hood 20 is supported.

  A hood inner panel 25 of the engine hood 20 is provided with a concave portion 26 that is recessed upward in a closed state, and a mounting seat portion 26 </ b> A to which a soft cushion rubber 32 is attached is provided in the concave portion 26. In the present embodiment, the seating surface of the mounting seat portion 26A is flat, and the soft cushion rubber 32 is fixed to the seating surface of the mounting seat portion 26A by bonding or the like. The amount of depression in the concave portion 26 up to the mounting seat portion 26A is smaller than the amount of protrusion of the soft cushion rubber 32 from the mounting seat portion 26A. A part of the outer peripheral part 26 </ b> B as an abutting part that forms the outer peripheral part of the concave part 26 can be in contact with the hard cushion rubber 30 (a protruding tip part in the present embodiment). Further, the outer peripheral portion 26 </ b> B that is a part of the hood inner panel 25 has a higher rigidity than the hard cushion rubber 30.

  Here, in the closed state of the engine hood 20, the soft cushion rubber 32 is in contact with the hard cushion rubber 30, and the outer peripheral portion 26B of the concave portion 26 is not in contact with the hard cushion rubber 30 (see FIG. 3B). ), The soft cushion rubber 32 is elastically deformable, and in a state where the outer peripheral portion 26B of the concave portion 26 is in contact with the hard cushion rubber 30 (see FIGS. 3C and 3D), the soft cushion rubber 32 is elastically deformed. Is limited, and only the hard cushion rubber 30 is elastically deformable.

  In other words, when the engine hood 20 is closed, the soft cushion rubber 32 abuts against the hard cushion rubber 30, and when the load in the closing direction (arrow C direction) is further input to the engine hood 20, a concave shape is formed. The soft cushion rubber 32 is elastically deformed in the closing direction of the engine hood 20 until the outer peripheral portion 26B of the portion 26 contacts the hard cushion rubber 30, and after the outer peripheral portion 26B of the concave portion 26 contacts the hard cushion rubber 30 The hard cushion rubber 30 is elastically deformed in the closing direction of the engine hood 20 while the elastic deformation state of the soft cushion rubber 32 is maintained.

(Action / Effect)
Next, the operation and effect of the above embodiment will be described.

  As shown in FIG. 2, the hard cushion rubber 30 is attached to the radiator support upper 14, and the soft cushion rubber 32 is provided separately from the hard cushion rubber 30 and attached to the engine hood 20. The soft cushion rubber 32 and the hard cushion rubber 30 are separated or contacted by opening / closing movement of the hood 20 (movement in the direction of arrow B or arrow C). When the engine hood 20 is closed, the soft hood rubber 32 is in series contact with the hard cushion rubber 30 between the engine hood 20 and the radiator support upper 14 so that the engine hood 20 is in series with the radiator hood upper 14. To support. In this way, the problem of peeling off between different types of rubber can be avoided by attaching the soft cushion rubber 32 and the hard cushion rubber 30 separately as separate bodies.

  When the engine hood 20 is closed, the soft cushion rubber 32 comes into contact with the hard cushion rubber 30. On the engine hood 20 side, the outer peripheral portion 26 </ b> B of the recessed portion 26 having a higher rigidity than the hard cushion rubber 30 is provided. In addition, the amount of depression in the concave portion 26 up to the mounting seat portion 26A is smaller than the amount of protrusion of the soft cushion rubber 32 from the mounting seat portion 26A, and the outer peripheral portion 26B of the concave portion 26 is formed in the hard cushion rubber 30. Since the abutment is possible, when a load in the closing direction (arrow C direction) is further input to the engine hood 20, as shown in FIG. 3B, the outer peripheral portion 26B of the concave portion 26 Until the soft cushion rubber 32 presses the hard cushion rubber 30 until the engine cushion 20 is in direct contact with the hard cushion rubber 30, the closing direction of the engine hood 20 (arrow C direction) gradually crushed elastically deformed. On the other hand, since the hard cushion rubber 30 has a higher hardness than the soft cushion rubber 32, it hardly deforms elastically.

  When the soft cushion rubber 32 is elastically deformed by a predetermined collapse amount (difference L (see FIG. 2) between the amount of protrusion of the soft cushion rubber 32 from the mounting seat portion 26A and the amount of depression of the concave portion 26 to the mounting seat portion 26A) (see FIG. 2). When moved by a predetermined deformation stroke), the outer peripheral portion 26B of the concave portion 26 abuts against the hard cushion rubber 30 as shown in FIG. After the outer peripheral portion 26B of the concave portion 26 comes into contact with the hard cushion rubber 30, the outer peripheral portion 26B of the concave portion 26 is replaced with the soft cushion rubber 32 as shown in FIG. Since the engine hood 20 is pressed in the closing direction (arrow C direction), the hard cushion rubber 30 is elastically deformed in the closing direction (arrow C direction) of the engine hood 20 while the elastic deformation state of the soft cushion rubber 32 is maintained. Crushing.

  As a result, the relationship between the total deformation amount S and the load F (deflection reaction force) in the soft cushion rubber 32 and the hard cushion rubber 30 is as shown by a solid line in FIG. In the graph, the point 3A is the data in the state of FIG. 3A, the point 3B is the data in the state of FIG. 3B, the point 3C is the data in the state of FIG. 3C, Point 3D indicates data in the state of FIG. In addition, a two-dot chain line 30L in FIG. 4 indicates the characteristics of the hard cushion rubber 30 alone, and a two-dot chain line 32L indicates the characteristics of the soft cushion rubber 32 alone.

  In the installed state where the engine hood 20 shown in FIG. 3A is closed and in a stable position, the deformation amount S and the load F (deflection reaction force) are both substantially zero as shown in FIG. . As shown in FIG. 3B, when a load in the closing direction (arrow C direction) is further input to the closed engine hood 20, the outer peripheral portion 26 </ b> B of the concave portion 26 becomes the hard cushion rubber 30. Until the contact, the soft cushion rubber 32 is elastically deformed in the closing direction (arrow C direction), so that the graph rises gently as shown in FIG. 4 (dominant region of the soft cushion rubber 32). As shown in FIG. 3C, when the outer peripheral portion 26B of the concave portion 26 comes into contact with the hard cushion rubber 30 (when the dominant region of the soft cushion rubber 32 ends), as shown in FIG. The gradual rise of the ends. As shown in FIG. 3D, when the outer peripheral portion 26B of the concave portion 26 presses the hard cushion rubber 30 instead of the soft cushion rubber 32, the hard cushion rubber 30 is elastic in the closing direction (arrow C direction). Since it is deformed, the graph rises rapidly as shown in FIG. 4 (dominant region of the hard cushion rubber 30).

  In this manner, until the outer peripheral portion 26B of the concave portion 26 shown in FIG. 2 contacts the hard cushion rubber 30, the load F (deflection reaction force) gradually increases and a characteristic approximate to that of the soft cushion rubber 32 is obtained. Then, after the outer peripheral portion 26B of the concave portion 26 comes into contact with the hard cushion rubber 30, the load F (deflection reaction force) increases rapidly, and the characteristics approximate to the hard cushion rubber 30 are obtained. The soft cushion rubber 32 is adjusted by adjusting the difference L (the dimension corresponding to the deformation stroke of the soft cushion rubber 32) between the protrusion amount of the 32 from the mounting seat portion 26A and the recess amount of the concave portion 26 to the mounting seat portion 26A. Since the characteristic range (range indicated by the symbol X in FIG. 4 (dominant region of the soft cushion rubber 32)) can be changed, tuning is relatively easy. It is possible to further approach the deformation characteristics - load ideals.

  Supplementally, the cushion rubber disposed on the support portion of the engine hood 20 includes an installation function of the engine hood 20, an impact absorption / interference prevention performance when the engine hood 20 is closed, an anti-flapping performance of the engine hood 20 during traveling, Many functions and performances are required, such as shock absorption performance at the time of a pedestrian collision and operation performance at the time of opening and closing the engine hood 20. Among these, for example, in the shock absorption / interference prevention performance when the engine hood 20 is closed, in order to avoid interference between the body 10 side and the engine hood 20, it has a rapid rise that does not deform beyond a certain amount of deformation. Cushion rubber properties are required. In addition, the shock absorption performance at the time of pedestrian collision and the operation performance at the time of opening and closing the engine hood 20 are cushion rubber having a gentle rise in order to suppress the impact due to sudden load fluctuations and to make the engine hood 20 easy to close. Characteristics are required. Generally, cushion rubber characteristics with a sharp rise are characteristics that can be easily obtained with high hardness rubber, and cushion rubber characteristics with a moderate rise are characteristics that are easy to obtain with rubber with low hardness. It is very difficult to obtain ideal load-deformation characteristics that combine both characteristics, and adjusting load-deformation characteristics according to individual vehicles from the viewpoint of manufacturing cost and work efficiency is difficult. Although difficult in the prior art, in this embodiment, by adjusting the difference L between the amount of protrusion of the soft cushion rubber 32 from the mounting seat portion 26A and the amount of depression in the concave portion 26 to the mounting seat portion 26A, the soft cushion rubber 32 is soft. Since the range of the characteristic approximate to the cushion rubber 32 (the range of the symbol X in FIG. 4 (the dominant region of the soft cushion rubber 32)) can be changed, ideal load-deformation characteristics It becomes relatively easy to close.

[Second Embodiment]

Note that the second embodiment is characterized by the shape of the concave portion 26, and the other configurations are substantially the same as those of the first embodiment, and therefore substantially the same components are the same. The reference numerals are attached and the description is omitted.

  As shown in FIG. 5, the concave portion 26 is recessed in a concave spherical shape, and the mounting seat portion 26 </ b> A has a concave spherical seat surface. The amount of depression in the concave portion 26 up to the mounting seat portion 26A is smaller than the amount of protrusion of the soft cushion rubber 32 from the mounting seat portion 26A. A part of the outer peripheral portion 26 </ b> B that forms the concave portion 26 (in this embodiment, an outer portion of the concave spherical surface) can be brought into contact with the hard cushion rubber 30.

  Also in the second embodiment described above, the problem of delamination between different types of rubbers can be avoided by approaching the ideal load-deformation characteristics by the same action as in the first embodiment.
