I can't. On the other hand, if you prepare a foamed molded product with a large thickness based on the widest gap between the roof panel and the base material, and sandwich the foamed molded product between the roof panel and the base material, the roof panel Further, in a portion where the undulation of the base material is large, the compression deformation of the foamed molded article becomes large, and a large force is applied to the base material due to the compression deformation, and the base material is locally deformed.

  On the other hand, when wiring members such as harness wires on the roof panel side of the base material, multiple locations are generally affixed to the base material using adhesive tape so as not to deviate from a predetermined position. Therefore, the material cost and the assembly man-hour are increased.

  The present invention has been made in view of such a point, and an object of the present invention is to effectively reduce noise in the passenger compartment to improve the ride comfort of the occupant, and to improve heat insulation and uselessness.

After the body is molded and the base material and the foam molded body are stacked, the routing member is inserted from the outer side surface of the foam molded body through the insertion path and pushed into the installation portion. It is characterized by manufacturing a ceiling molding material .

  In the first aspect of the invention, it is difficult to form a non-contact portion between the foam molded body and the base material, and between the foam molded body and the roof panel. Air can no longer flow between the material and the roof panel, and wind noise can be prevented. Moreover, since the foaming molding provided between the base material and the roof panel blocks the rain sound that travels toward the vehicle interior side, the rain sound that can be heard in the vehicle interior can be reduced. As a result, the noise in the passenger compartment can be effectively reduced to improve the ride comfort of the occupant, and the heat insulation can be improved to eliminate wasteful power consumption. Can be reduced. Furthermore, if the foamed molded product is pressed against the base material and the roof panel, the foamed molded product suppresses the vibration of the roof panel while the vehicle is running, and noise generated from the vibration of the roof panel can be reduced.

In addition, since the housing groove is formed in the foamed molded body to accommodate and accommodate the wiring member, the wiring member can be fixed to the foamed molded body by housing the wiring member in the housing groove. In addition, it is no longer necessary to attach many locations of the routing member to the base material with an adhesive tape or the like as in the prior art, and the work of sticking these routing members to the base material can be simplified and the number of assembly steps can be reduced. .

Further, when the housing groove is formed on the outer side surface of the foam molded body, the routing member can be assembled from the upper side of the foam molded body, and the workability is excellent. In addition, since the routing member can be assembled even after the foam molded body is stacked on the base material, the work on the assembly line is quick and easy, and improvement in work efficiency can be expected. Furthermore, maintenance work such as replacement of the routing member can be easily performed.

In the second invention, the housing groove includes an installation portion in which the routing member is installed, and an insertion path that communicates from the surface of the foam molded body to the installation portion, where the width of the insertion path is relative to the width of the installation portion. Because it is narrow, the routing member accommodated in the installation part is difficult to come back through the narrow insertion path, and can be easily and firmly fixed by accommodating the routing member in the accommodation groove, It is possible to prevent the wiring member from being pulled out and displaced.

When the foamed molded product is made of a low-rebound elastic material, when the ceiling molded material is attached to the roof panel, the foamed molded product made of the low-repulsive elastic material has become well adapted to large undulations. Compared to the first invention, a non-contact portion between the foam molded body, the base material, and the roof panel is further difficult to be formed. Moreover, since the pressure of the contact part of a foaming molding, a base material, and a roof panel comes to disperse | distribute, it can prevent that a local force is added to a base material and deform | transforms. Furthermore, even if the base material and roof panel have multiple variations and the shape of the base material and roof panel is partially different, the foamed molded product will fit well in accordance with each shape Therefore, it can be used as a versatile ceiling molding material. In addition, since a low-rebound elastic material having high vibration damping properties is used for the foamed molded product, the vibration of the roof panel during the traveling of the vehicle can be further suppressed compared to the first invention, and the roof panel Noise generated by vibration can be prevented.

In the third invention, the thickness of the foam molding corresponds to the vertical width between the roof panel and the base material, and when the ceiling molding material is attached to the roof panel, the outside of the foam molding body Comes into contact with the interior side of the roof panel substantially uniformly. Therefore, the outer side of the foam molded body is substantially uniformly compressed and deformed, and it is possible to prevent the base material from being deformed by applying a large local force.

In the fourth and fifth inventions, the foamed molded body along the vehicle interior side of the base material and along the vehicle interior side of the roof panel can be molded with the molding die. It can effectively reduce the noise of the passengers and improve the ride comfort of the occupant, improve the heat insulation and eliminate unnecessary power consumption, and reduce the assembly man-hours at low cost. . Furthermore, since the base material, the foam molded body and the wiring member are separately carried into the automobile assembly line and sub-assembled by the assembly line, it can be easily applied to an existing automobile assembly line. Easy to incorporate.

When the above foam molded body receiving groove for simultaneously routing member when it is foamed molded in the mold is formed, similar to the first invention, paste wiring member to the substrate The number of assembly steps can be reduced by simplifying the operation.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiment is merely exemplary in nature.

  FIG. 1 shows a vehicle V (vehicle body) according to an embodiment of the present invention. A roof panel R is located above the vehicle V. As shown in FIGS. 3 and 4, the roof panel R includes a substantially rectangular roof panel outer R <b> 1 serving as an outer plate portion of the vehicle V and a pair of left and right edges of the roof panel outer R <b> 1 extending in the vehicle front-rear direction. A roof side rail R2 and a roof reinforcement R3 extending in the vehicle width direction along the lower surface of the roof panel outer R1 are provided. The roof reinforcement R3 has a substantially hat-shaped cross section, and a plurality of roof reinforcements R3 are arranged in parallel in the vehicle longitudinal direction.

On the vehicle interior side of the roof panel R, a vehicle ceiling molding material 1 serving as a design surface of the vehicle interior ceiling is disposed. The ceiling molding material 1 has a substantially rectangular shape extending in the vehicle front-rear direction, and is foam-molded to be disposed between the panel-like base material 3 facing the vehicle interior side and the base material 3 and the roof panel R. It has a body 9 and a routing member 20 that is routed outside the passenger compartment of the foam molded body 9 and has a gently curved shape with the center portion located above.

  Although not shown, the substrate 3 has a structure in which a surface material and a back material are laminated via a reinforcing layer such as glass fiber on a substrate body layer made of hard foamed urethane. And formed by a conventionally known method.

  The foam molded body 9 is a low resilience elastic material made of foamed urethane (foamed urethane U1 shown in FIG. 11, for example, soft urethane No. 5 manufactured by SBU), and is disposed between the substrate 3 and the roof panel R. It is installed. The shape of the foam molded body 9 on the vehicle interior side is substantially equal to the shape of the base material 3 on the vehicle exterior side, and the shape on the vehicle interior side is substantially the same as the shape of the roof panel R on the vehicle interior side. As shown in FIGS. 3 and 4, an accommodation groove 30 for accommodating the routing member 20 is formed on the outside of the passenger compartment of the foam molded body 9. As shown in FIGS. 3 and 4, the vertical width of the roof panel R and the base material 3 is wider at the center than at both front and rear ends of the vehicle, and at the center from both ends of the left and right sides of the vehicle. The width of the foamed molded product 9 corresponds to the vertical width of the roof panel R and the base material 3. The foam molded body 9 is disposed between the base material 3 and the roof panel R, and the vehicle interior side is pressed against the vehicle exterior side of the base material 3 while the vehicle interior side is the vehicle interior of the roof panel R. It comes to be pressed inward.

  The low-rebound elastic material generally has the property of having both elasticity and viscosity, and when applied to a large undulation location, it can be placed along the location without any gaps and the pressure at the contact portion can be reduced. Since it can be dispersed, when the foam molded body 9 is attached between the base material 3 and the roof panel R, the foam molded body 9 can be placed along the portion of the roof reinforcement R3 having a large undulation, Moreover, the pressure at the contact portion is dispersed so that the base material 3 is not locally deformed.

The foamed molded product 9 has a so-called closed cell structure in which the bubbles inside are separated by a wall and are not connected to each other, and has high heat insulation properties, and its density is 0.07 g / cm ³ . The density of the foamed molded body 9 is preferably 0.02 to 0.07 g / cm ³ so as not to increase the weight of the vehicle V.

  Further, as shown in FIG. 5, the end portion of the foam molded body 9 positioned in front of the vehicle is positioned at the upper part of the front pillar Fp connected to the roof panel R. The base material 3 at a position corresponding to the front pillar Fp is not bent toward the front pillar Fp side. Accordingly, even if no member such as chip urethane is disposed between the front pillar Fp and the base material 3, the base material 3 does not bend toward the front pillar Fp side, and the pillar trim located inside the front pillar Fp. A gap is not formed between Pt and the base material 3, and costs can be reduced and design in the vehicle interior can be improved. Not only the front pillar Fp but also the center pillar and the rear pillar portion are not shown in the figure, so that no gap is formed between the trim and the base material 3 by the foamed molded body 9 as described above. The design of the passenger compartment can be improved.

  The routing member 20 includes a wiring 5 and a pipe 7. As shown in FIG. 2, the wiring 5 includes a harness wire 5a and an antenna wire 5b. The harness wire 5a extends rearward along the outer peripheral edge of the foam molded body 9 from the front on the right side in the vehicle width direction, and extends toward the left side in the vehicle width direction from the vehicle front-rear direction central portion and the rear portion. Thus, the roof lamps 5c are respectively located on both sides in the vehicle width direction at the center in the vehicle longitudinal direction and on the left side in the vehicle width direction behind the vehicle. The antenna wire 5b extends rearward along the outer peripheral edge of the foam molded body 9 from the front on the left side in the vehicle width direction.

  Although not shown, the pipe 7 is a washer pipe for delivering the washer fluid from the engine room in front of the vehicle to the rear window glass. As shown in FIG. 2, the pipe 7 is arranged from the front on the left side in the vehicle width direction to the rear along the antenna line 5b. It extends.

  And the said wiring 5 and the piping 7 are accommodated in the accommodation groove | channel 30 formed in the compartment outer surface of the foaming molding 9, as shown in FIG. Specifically, as shown in FIG. 10, the housing groove 30 is formed in accordance with the state in which the routing member 20 is routed on the outer side surface of the foam molded body 9, and the routing member 20 is installed. And the installation part 31 accommodated and the insertion path 32 which connects the surface and the installation part of the foaming molding 9 are provided. The installation portion 31 substantially matches the shape and size of the routing member 20, and the insertion path 32 is formed slightly smaller than the shape and size of the routing member 20. Since the width of the insertion path 32 is slightly smaller than the width of the routing member 20, the routing member 20 is strongly pushed toward the housing groove 30 to place the routing member 20 in the installation portion 31. In addition, the routing member 20 positioned in the installation portion 31 is not easily removed from the receiving groove 30.

  Next, the manufacturing method of the ceiling molding material 1 for vehicles is demonstrated. At the time of manufacture, a forming die 10 having a fixed die (first die) 11 and a movable die (second die) 13 that are opposed to each other as shown in FIGS. 6 to 9 is prepared. On the upper surface of the fixed mold 11, a lower molding surface 11 a corresponding to the shape of the shape surface 3 a outside the passenger compartment of the base material 3 is formed. Further, an upper molding surface 13 a having a shape along the shape surface Ra of the roof panel R on the vehicle interior side is formed on the lower surface of the movable mold 13. Further, as shown in FIG. 6, the upper molding surface 13 a of the movable mold 13 is provided with groove forming portions 13 b and 13 c for forming an accommodation groove 30 for accommodating the wiring 5 and the pipe 7. The groove forming part 13 c is formed with substantially the same width as the wiring 5 and the pipe 7, and the groove forming part 13 b is formed with substantially the same width as the wiring 5.

  First, the base material 3 molded by a conventionally known method using a molding die (not shown) is prepared. Further, as shown in FIG. 6, the mold 10 is closed as shown in FIG. 7 after the mold 10 is opened.

  As shown in FIG. 7, after the mold 10 is closed, the foam molded body 9 is placed in the cavity 10 a formed between the lower molding surface 11 a of the fixed mold 11 and the upper molding surface 13 a of the movable mold 13. After the foamed resin material 90 is injected and injected with an injection machine (not shown), the foamed resin material 90 is heated and foamed with a heating device (not shown). Then, as shown in FIG. 8, the foamed molded product 9 fills the cavity 10a, and at the same time, the housing groove 30 for housing the wiring 5 and the pipe 7 is formed.

  After this molding, as shown in FIG. 9, the movable mold 13 is retracted from the fixed mold 11 to open the mold 10. At this time, the groove forming portions 13 b and 13 c are also removed from the housing groove 30 of the foamed molded body 9 at the same time. Although the width of the insertion path 32 of the accommodation groove 30 is narrower than the width of the installation portion 31, the foamed molded body 9 has elasticity, so that the groove formation portions 13 b and 13 c are easily pulled out from the accommodation groove 30. Thereafter, the foamed molded body 9 is removed from the mold 10.

  Thereafter, the routing member 20 is inserted and assembled into the housing groove 30 of the foamed molded body 9. The foam molded body 9 and the base material 3 are overlapped to manufacture the vehicle ceiling molded material 1.

  Next, the evaluation result about the sound insulation performance of the ceiling molding material 1 for vehicles which concerns on embodiment of this invention is demonstrated.

FIG. 11 is a graph in which the horizontal axis represents frequency and the vertical axis represents sound transmission loss. The higher the sound transmission loss at each frequency, the higher the sound insulation performance. D1 indicates data acquired without the foamed molded product 9 between the roof panel R and the base material 3, D2 indicates data acquired using the urethane foam U1 for the foamed molded product 9, and D3 indicates The data acquired by using foamed urethane U2 (for example, slab urethane manufactured by BS: density 0.02 g / cm ³ ) for the foamed molded body 9 are shown.

  In recent years, the sound insulation performance is improved in the audible range of 1.0 kHz to 2.5 kHz in recent years, and also in the high frequency region of 3.0 kHz to 5.0 kHz as the performance of automobiles increases. There is a demand to improve performance. On the other hand, as shown in FIG. 11, the vehicle ceiling molding material 1 (D2, D3) in which the urethane foams U1 and U2 are disposed between the roof panel R and the base material 3 includes the roof panel R and the base material. Compared to the vehicle ceiling molding material 1 (D1) without the foam molding 9 between the material 3 and the material 3, it has high sound insulation performance. In particular, the urethane foam U1 (D2) has higher sound insulation performance than the urethane foam U2 (D3) in a high frequency region of 3.0 kHz to 5.0 kHz. Therefore, it is possible to obtain a vehicle ceiling molding material 1 having high sound insulation performance by using the urethane foams U1 and U2 for the foam molded body 9, and furthermore, by using the urethane foam U1 for the foam molded body 9, a high frequency region can be obtained. It can be seen that the vehicle ceiling molding material 1 having high sound insulation performance can be obtained.

  As described above, according to the embodiment of the present invention, the foam molded body 9 along the vehicle interior side of the base material 3 and along the vehicle interior side of the roof panel R can be molded with the molding die 10. 3 and between the foam molded body 9 and the roof panel R, it is difficult to form a non-contact portion, so that the heat insulation is improved and the vehicle 3 is traveling between the base material 3 and the roof panel R during traveling. Air can no longer flow and wind noise can be prevented. In addition, since the foamed molded body 9 provided between the base material 3 and the roof panel R blocks the rain sound that travels toward the vehicle interior side, the rain sound that can be heard in the vehicle interior can be reduced. Furthermore, since the foam molded body 9 is pressed against the roof panel R, the foam molded body 9 can suppress vibration of the roof panel R while the vehicle V is traveling, and noise generated from the vibration of the roof panel R can be reduced. .

  In addition, since the foamed molded body 9 is molded in the molding die 10 and at the same time the housing groove 30 for housing the wiring 5 and the piping 7 is formed, many portions of the wiring 5 and the piping 7 are adhesive tape or the like as in the past. Thus, it is not necessary to attach the wires 5 and the cost, and the work of attaching the wires 5 and the pipes 7 to the base material 3 can be simplified to reduce the number of assembling steps.

  Moreover, by making the width of the insertion path 32 of the accommodation groove 30 narrower than the width of the installation portion 31, the wiring 5 and the pipe 7 can be easily and firmly fixed, and the removal can be prevented. . As a result, noise in the passenger compartment can be effectively reduced, passenger comfort can be improved, thermal insulation can be improved, and wasteful power consumption can be eliminated. Can be reduced.

  In addition, when the ceiling molding material 1 is attached to the roof panel R, the foam molded body 9 becomes well adapted to places with large undulations, and between the foam molded body 9 and the base material 3 and the foam molded body 9. And the roof panel R are more difficult to form a non-contact portion. Moreover, since the pressure of the contact part of the foaming molding 9, and the base material 3 or the roof panel R comes to disperse | distribute, it can prevent that a local force is added to the base material 3 and it deform | transforms. . Furthermore, even if the base material 3 and the roof panel R have a plurality of variations, and the shapes of the base material 3 and the roof panel R are partially different, the foam molded body 9 has the respective shapes. The common ceiling molding material 1 can be applied to different base materials 3 and roof panels R, and the versatile ceiling molding material 1 can be obtained. In addition, since a low-rebound elastic material having high vibration damping properties is used for the foamed molded body 9, vibration of the roof panel R during traveling of the vehicle V can be further suppressed, and generated by vibration of the roof panel R. Can prevent noise.

  Furthermore, the base material 3, the foam molded body 9 and the routing member 20 are separately manufactured and carried into an automobile assembly line, and the base material 3, the foam molded body 9 and the routing member 20 are assembled near the assembly line. Therefore, it is easy to apply to existing automobile assembly lines.

  Furthermore, when the thickness of the foam molded body 9 corresponds to the vertical width between the roof panel R and the base material 3 and the ceiling molded material 1 is attached to the roof panel R, the vehicle of the foam molded body 9 The outdoor side comes into contact with the interior side of the roof panel R substantially uniformly. Accordingly, the outside of the passenger compartment of the foamed molded body 9 is compressed and deformed substantially uniformly, and it is possible to prevent the base material 3 from being deformed by applying a large local force.

  In the embodiment of the present invention, the wiring member 20 is assembled in the housing groove 30 of the foam molded body 9 and then overlapped with the base material 3. After stacking 9, the routing member 20 may be assembled to the accommodation groove 30.
