Description

[Technical field]

[0001] The present invention relates to a seal structure for a vehicle. [Background technology]

[0002] Efforts aimed at mitigating or reducing the impact of climate change have been ongoing for some time now, and research and development into reducing carbon dioxide emissions is being carried out to achieve this goal. As part of these efforts, measures are being considered to simplify painting, such as reducing the number of times that outer panels, which make up the decorative surface of a vehicle, are painted. For example, Patent Document 1 proposes a technique in which the inner panel of a vehicle is left metal, the outer panel is replaced from metal to resin, and the inner panel and the outer panel are joined together with an adhesive.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 6-340221 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the method proposed in Patent Document 1, since the thermal expansion coefficients of the metal inner panel and the resin outer panel are different, there is a risk that the outer panel will bend if the entire periphery is bonded with adhesive. One possible solution is to stop gluing the inner panel and outer panel together and use slide clips or similar to support the panels while allowing for thermal expansion. However, with such a configuration, there is a risk that sound insulation will be impaired because the gap between the inner panel and the outer panel is not sealed.

[0005] The present invention has been made in consideration of the above-mentioned points, and aims to provide a sealing structure for a vehicle that can suppress the occurrence of deflection due to differences in thermal expansion coefficients and the deterioration of sound insulation that occurs when a resin outer panel is used. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the vehicle sealing structure device of the present invention is characterized in comprising a metal inner panel constituting a vehicle body or a door supported so as to be able to open and close a vehicle body opening, a resin outer panel arranged on the vehicle exterior panel surface of the inner panel and movably along the door surface of the inner panel, and a sealing member sandwiched between the inner panel and the outer panel. Effect of the Invention

[0007] According to the present invention, it is possible to provide a vehicle seal structure that can suppress the occurrence of deflection due to differences in thermal expansion coefficients that arise when a resin outer panel is used, and the deterioration of sound insulation. Furthermore, by simplifying the painting of outer panels, carbon dioxide emissions during vehicle manufacturing will be reduced, thereby contributing to mitigating or reducing the impact of climate change.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] First Embodiment An embodiment of the present invention will be described in detail with reference to Figures 1-3 and the left side of Figure 4. In the description, the same elements are given the same reference numerals, and duplicated description will be omitted. The vehicle V is equipped with a front door DF that is supported so as to be able to open and close a front seat entrance opening to the side of the vehicle, and a rear door DR that is supported so as to be able to open and close a rear seat entrance opening to the side of the vehicle (see Figure 1). The vehicle seal structure S1 of this embodiment is provided at various locations in the periphery of the door. For example, the vehicle seal structure S1 is provided on the lower peripheral edge of the rear door DR and on the rear peripheral edge of the front door DF (see FIG. 2-4).

[0010] The seal members 10 constituting the vehicle seal structure S1 of this embodiment and arranged on the lower peripheral edge of the rear door DR and the rear peripheral edge of the front door DF are separate members but have the same cross-sectional shape. In other words, the rear peripheral portion of the front door DF is configured similarly to the lower peripheral portion of the rear door DR. In this embodiment, therefore, the front door DF and the rear door DR are both referred to as door D, and the configuration of the peripheral portion thereof will be described.

[0011] The doors D are so-called hinged doors, with the front edge of the door supported by the front portion of each entrance / exit via a hinge (not shown), and the rear edge of the door swinging. The door D includes an inner panel 20 and an outer panel 30. In the vehicle seal structure S1 of this embodiment, the seal member 10 is disposed in a sandwiched state between the inner panel 20 and the outer panel 30, and seals between the inner panel 20 and the outer panel 30. Hereinafter, the state in which the seal member 10 is sandwiched between the outer panel 30 and the inner panel 20 will be referred to as a sealed sandwiched state.

[0012] The inner panel 20 is formed by joining a plurality of metal plates together. The inner panel 20 is provided with a slide nut 21 protruding from a plate surface (hereinafter referred to as an inner outer surface 20a) facing the vehicle exterior. The outer panel 30 is configured from a plate-like member made of resin, and is disposed along the plate surface of the inner panel 20 on the inner outer surface 20a. The outer panel 30 also has a general portion 31 and an extension portion 32 .

[0013] The general portion 31 extends in a direction along the door surface and constitutes the main body of the outer panel 30. The plate surface facing the vehicle exterior (hereinafter referred to as the outer surface 30a) constitutes the design surface of the door D. Further, the general portion 31 is provided with a slide rail 33 on a plate surface on the vehicle interior side (hereinafter referred to as the outer inner surface 30b). The slide rail 33 includes a rail portion 34 along which the slide nut 21 is movable on the outer inner surface 30b.

[0014] Since the slide nut 21 is movable within the rail portion 34, the outer panel 30 is movable along the plate surface of the inner panel 20 on the inner outer surface 20a. Furthermore, since the outer panel 30 is movable on the inner panel 20, the occurrence of bending due to the difference in thermal expansion coefficient between the inner panel 20 and the outer panel 30 is suppressed. In addition, the slide nut 21 is disposed within the rail portion 34 and cooperates with it to hold the outer panel 30 on the inner outer surface 20a. The slide nut 21 is not joined to the inner panel 20 by welding or the like, but is arranged so as to be detachable from the inner panel 20. In other words, the slide nut 21 is temporarily assembled to the slide rail 33 and then screwed onto the bolt 23 inserted into the bolt hole 22 opening in the inner panel 20, thereby being installed on the inner panel 20.

[0015] The extension portion 32 has a generally trapezoidal cross section, and is formed integrally with the general portion 31 along the periphery of the outer inner surface 30b as a protrusion that protrudes from the outer inner surface 30b toward the vehicle interior. In other words, the extension 32 forms a step on the periphery of the outer inner surface 30b. The extension 32 prevents water that has entered inside the outer panel 30 from directly hitting the contact portion between the seal member 10 and the outer inner surface 30b.

[0016] Next, the seal member 10 will be described. The seal member 10 is made of a material having flexibility and elasticity, such as rubber. In the sealed sandwiched state, the seal member 10 is brought into close contact with the outer inner surface 30b and the inner outer surface 20a by a restoring force, and exerts a sealing property between the inner panel 20 and the outer panel 30. The seal member 10 includes a base portion 40 and a panel seal portion 50 .

[0017] The base portion 40 is composed of an outer wall 41, an inner wall 42, and a bottom wall 43, which are integrally formed. The outer wall 41 is disposed so as to extend along a direction from the peripheral edge side of the plate surface of the inner outer surface 20a toward the center side of the plate surface. In the following description, the peripheral side of the plate surface of the inner outer surface 20a will be referred to as the door surface peripheral side, and the central side of the plate surface will be referred to as the door surface central side. The direction from the peripheral edge side of the door surface toward the center side of the door surface is referred to as the door surface central peripheral direction. The portion of the outer wall 41 that faces the inner outer surface 20a is set to a flat surface (hereinafter, referred to as a base flat surface 44). In the sealed sandwiched state, the base flat surface 44 is in close contact with the outer surface of the inner member.

[0018] The inner wall 42 is disposed so as to extend along the central periphery of the door surface of the vehicle interior side plate surface of the inner panel 20 (hereinafter referred to as the inner inner surface 20b). The inner wall 42 is provided with a pair of base ribs 45 that protrude toward the inner panel 20 at a location facing the inner inner surface 20 b of the inner panel 20 . The bottom wall 43 integrally connects the peripheral edge of the outer wall 41 and the peripheral edge of the inner wall 42 .

[0019] The base portion 40 has an outer wall 41, an inner wall 42, and a bottom wall 43, and has a cross section that is generally U-shaped. The base portion 40 is disposed on the inner panel 20 with the periphery of the inner panel 20 enclosed within the U-shaped groove. The panel seal portion 50 includes a seal lip 51 , an inverted lip 52 , and a restraining lip 53 .

[0020] The seal lip 51 stands from the door surface central end of the outer wall 41 outward in the vehicle width direction toward the outer panel 30, and extends along the outer inner surface 30b toward the door surface peripheral edge side. That is, the seal lip 51, together with the outer wall 41 of the base portion 40, forms a cross section having a substantially V-shaped groove shape. The seal lip 51 has flexibility and elasticity, and in the sealed sandwiched state, the surface on the outer panel side is brought into close contact with the outer inner surface 30b by a restoring force. The shape and dimensions of the seal lip 51 are set so that the tip of the seal lip 51 does not come into contact with the extension 32 of the outer panel 30 in the sealed and sandwiched state.

[0021] The inverted lip 52 is provided obliquely against the inner panel 20 , extending from the tip of the seal lip 51 toward the inner panel 20 and toward the center of the door surface of the inner panel 20 . In other words, the inverted lip 52 stands upright while forming an acute angle with the seal lip 51 . The shape and dimensions of the inverted lip 52 are set so that its tip abuts against and is held by the outer wall 41 of the base portion 40 in the sealed and sandwiched state.

[0022] The restraining lip 53 is located closer to the peripheral edge of the door surface than the inverted lip 52, and stands upright from the point where the outer wall 41 and bottom wall 43 of the base portion 40 are connected toward the boundary between the general portion 31 and the extension portion 32 of the outer panel 30. The shape and dimensions of the restraining lip 53 are set so that its tip abuts and is held on the general portion 31 side of the boundary between the general portion 31 and the extension portion 32 in the sealed and clamped state.

[0023] Next, the function of the seal member 10 will be described. When the seal member 10 constructed as described above is in a sealed sandwiched state in which it is sandwiched between the outer panel 30 and the inner panel 20, a restoring force acts on the seal member 10 as it tries to return to its original shape. This restoring force causes the outer wall 41 of the base portion 40 to come into close contact with the inner outer surface 20a of the inner panel 20, and causes the seal lip 51 to come into close contact with the outer inner surface 30b.

[0024] Furthermore, due to the restoring force, the tip of the inverted lip 52 abuts against the vehicle exterior side surface 41 a of the outer wall 41 , and the tip of the restraining lip 53 abuts against the outer inner surface 30 b of the general portion 31 . With each portion being in close contact and abutting against each other in this manner, the seal member 10 seals between the inner panel 20 and the outer panel 30. For example, when water infiltrates between the panels during rain or when washing a car, the water is first blocked by the restraining lip 53 . Next, the water that cannot be blocked by the restraining lip 53 is blocked by the sealing lip 51 and the inverted lip 52 .

[0025] Furthermore, water that cannot be blocked by the inverted lip 52 is guided into the V-groove between the seal lip 51 and the outer wall 41, moves inside the V-groove, and is discharged to the outside from a discharge portion (not shown). In addition, as a result of the restoring force acting, a component of the restoring force acts on the base portion 40 from the peripheral edge side of the door surface toward the center side of the door surface. This prevents the seal member 10 from falling off the inner panel 20. Furthermore, when the seal member 10 moves from the inner panel 20 toward the peripheral edge side, the tip of the restraining lip 53 engages with the base of the extension portion 32, preventing it from falling off.

[0026] Next, the effects of this embodiment will be described. In the vehicle seal structure S1 of this embodiment, a seal member 10 is sandwiched between an inner panel 20 made of metal and an outer panel 30 made of resin. Further, the outer panel 30 is disposed so as to be movable along the door surface of the inner panel 20. This makes it possible to ensure sealing performance around the periphery of the door surface while allowing for differences in thermal expansion between the inner panel 20 and the outer panel 30. In other words, it is possible to suppress the occurrence of bending due to the difference in thermal expansion coefficient between the resin outer panel 30 and the inner panel 20, and the deterioration of sound insulation. Furthermore, by ensuring the sealing performance, the painting of the inner panel 20 can be simplified by, for example, limiting it to an anti-rust paint. This will reduce carbon dioxide emissions during vehicle manufacturing, ultimately contributing to mitigating or reducing the effects of climate change.

[0027] In the vehicle seal structure S1 of the present embodiment, the seal member 10 is composed of a base portion 40 and a panel seal portion 50. The base portion 40 has a cross section in a generally U-shaped groove shape, and is disposed within the U-shaped groove so as to encompass the periphery of the inner panel 20 . In addition, in the sealed and sandwiched state, the panel seal portion 50 is in close contact with the outer inner surface 30b of the outer panel 30.

[0028] With this configuration, the periphery of the inner panel 20 is covered by the base portion 40, so that the periphery of the inner panel 20 can be prevented from being exposed to water and sunlight. This makes it possible to suppress the occurrence of rust on the peripheral edge of the inner panel 20 and to make any rust that does occur less noticeable. Furthermore, since the seal member 10 is fixed by enclosing the peripheral edge of the inner panel 20 within the U-shaped groove of the base portion 40, it is possible to prevent the panel seal portion 50 from shifting out of position. This makes it possible to improve the sealing performance between the inner panel 20 and the outer panel 30.

[0029] In the vehicle seal structure S1 of the present embodiment, the seal lip 51 extends from the door surface central end of the outer wall 41 constituting the base portion 40 toward the outer panel 30 and along the door surface peripheral edge side of the outer panel 30. With this configuration, even if water seeps in between the panels during rain or when washing the car, the water is received by the V-shaped groove formed by the seal lip 51 and the outer wall 41. This makes it possible to prevent water from entering between the outer panel 30 and the inner panel 20 through the end of the seal lip 51. Furthermore, the improved sealing performance can improve sound insulation.

[0030] In the vehicle seal structure S1 of the present embodiment, the inverted lip 52 is erected obliquely with respect to the inner panel 20 from the tip end portion of the seal lip 51 toward the center of the door surface of the inner panel 20. With this configuration, the restoring force of the inverted lip 52 is applied to the tip portion of the seal lip 51. This improves the force with which the seal lip 51 adheres to the outer inner surface 30b, thereby further improving the sealing performance. In addition, the reaction force that the seal lip 51 receives from the outer inner surface 30b pushes the outer wall of the base portion toward the center of the door surface through the inverted lip, increasing the retraction force and preventing the base portion 40 from moving toward the peripheral edge of the door surface. Furthermore, the force with which the seal lip 51 adheres to the outer inner surface 30b is improved, thereby improving sound insulation.

[0031] In the vehicle seal structure S1 of the present embodiment, the restraining lip 53 is located closer to the peripheral edge of the door surface than the inverted lip 52. With this configuration, the restraining lip 53 acts as an obstacle, and the amount of water that enters the V-shaped groove formed by the seal lip 51 and the outer wall 41 can be reduced.

[0032] In the seal structure for a vehicle S1 of the present embodiment, the extension portion 32 is formed integrally with the general portion 31 along the circumferential direction on the peripheral edge of the outer inner surface 30b. The extension portion 32 has a generally trapezoidal cross section and serves as a protrusion that protrudes from the outer inner surface 30b toward the vehicle interior, forming a step on the periphery of the outer inner surface 30b. The tip of the seal lip 51 abuts against the general portion 31 at the boundary between the general portion 31 and the extension portion 32 . With this configuration, when it rains or when the car is washed, strong water hits the extension portion 32 instead of the tip of the seal lip 51, thereby achieving higher sealing performance.

[0033] <Second embodiment> Next, a vehicle seal structure S2 according to a second embodiment will be described in detail with reference to the right side of FIG. The vehicle seal structure S2 of this embodiment is arranged to provide a seal between the rear edge of the front door DF and the front edge of the rear door DR at the center pillar portion of the vehicle V. In the description, the same elements as those in the first embodiment described above are given the same reference numerals, and duplicated descriptions will be omitted.

[0034] In the seal structure for a vehicle S2 of this embodiment, the configuration of the outer panel 30 and the configuration of the seal member 10 are different from those of the first embodiment. The outer panel 30 of this embodiment does not include the extension portion 32, and only includes the general portion 31. In other words, the peripheral edge portion of the outer inner surface 30 b is a flat surface continuing from the general portion 31 . The seal member 10 also includes an inter-panel seal 54 . In this embodiment, the outer panel 30 of the front door DF serves as an exterior panel PF adjacent to the outer panel 30 of the rear door DR.

[0035] The inter-panel seal 54 extends from the tip of the seal lip 51 towards the peripheral edge of the door surface. In the seal clamped state, the seal lip 51 is in close contact with the outer inner surface 30b, and the inter-panel seal 54 is in contact with the extension 32 of the adjacent exterior panel PF (the outer panel 30 of the front door DF) due to its restoring force. In other words, by providing the inter-panel seal 54, the gap between the outer panel 30 and the exterior panel PF is blocked. By closing this gap, direct sunlight entering the inner panel 20 and the inside of the door D through the gap is blocked, and the infiltration of rainwater and the like is suppressed. In addition, in conjunction with the provision of the inter-panel seal 54, the inversion lip 52 and the restraining lip 53 have been modified.

[0036] The inverted lip 52 is modified so that it extends from the middle of the inter-panel seal 54 toward the inner panel 20 and obliquely stands upright toward the center of the door surface of the inner panel 20. The restraining lip 53 is modified so that its tip comes into contact with the inner tip of the inter-panel seal 54 in the seal clamping state. In the seal sandwiched state, the restraining lip 53 is flexibly deformed, and the restoring force of the restoring lip 53 causes the inter-panel seal 54 to abut more firmly against the adjacent exterior panel PF.

[0037] As described above, this embodiment can achieve the same effects as the first embodiment. Moreover, with such a configuration, it is possible to ensure sealing between the outer panel 30 and the adjacent exterior panel PF without increasing the number of parts. In other words, the inter-panel seal 54 blocks direct sunlight from penetrating into the inner panel 20 and the inside of the door D through the gap between the outer panel 30 and the exterior panel PF, and also prevents rainwater and the like from entering. This suppresses deterioration over time of the paint on the inner panel 20 and the inside of the door D, so that the required weather resistance can be fully achieved with simplified painting. In addition, simplifying the painting process will reduce carbon dioxide emissions during vehicle manufacturing, thereby contributing to mitigating or reducing the impact of climate change.

[0038] <Third embodiment> Next, a vehicle seal structure S3 according to a third embodiment will be described in detail with reference to FIG. In the description, the same elements as those in the first embodiment described above are given the same reference numerals, and duplicated descriptions will be omitted. The vehicle seal structure S3 of this embodiment is arranged to provide a seal between the front door DF and the front fender FF at the front edge portion of the front door DF.

[0039] The outer panel 30 of the front fender FF serves as an exterior panel PF adjacent to the outer panel 30 of the front door DF. Further, the vehicle seal structure S3 of the present embodiment has a configuration of the inter-panel seal 55 corresponding to a configuration in which the outer panel 30 has the extension portion 32. The configurations of the base portion 40, the sealing lip 51, the inverted lip 52, and the restraining lip 53 are similar to those in the first embodiment.

[0040] The seal member 10 also includes an inter-panel seal 55 . The inter-panel seal 55 includes a contact portion 56 , a resilient contact portion 57 , and a constricted portion 58 . The contact portion 56 has a generally L-shaped cross section, and stands from the bottom wall 43 of the base portion 40 toward the extension portion 32 of the outer panel 30 . The tip of the contact portion 56 is formed into a flat surface that can come into close contact with the end face of the extension portion 32 . The elastic contact portion 57 extends from the abutment portion 56 toward the periphery of the door surface toward the adjacent exterior panel PF (front fender FF), and is in elastic contact with the inner surface of the exterior panel PF.

[0041] The constricted portion 58 is a portion that is set between the contact portion 56 and the elastic contact portion 57 and has a smaller thickness. When the front door DF is closed, the constricted portion 58 bends to maintain a seal between the contact portion 56 and the extension portion 32, and between the elastic contact portion 57 and the adjacent exterior panel PF. When water is sprayed with great force between the outer panel 30 and the front fender FF with the front door DF closed, the contact portion 56 is kept in contact with the end face of the extension portion 32 by bending at the narrowed portion 58. In other words, by providing the inter-panel seal 55, the gap between the outer panel 30 and the exterior panel PF is sealed. By closing this gap, direct sunlight entering the inner panel 20 and the inside of the door D through the gap is blocked, and the infiltration of rainwater and the like is suppressed.

[0042] As described above, this embodiment can achieve the same effects as the second embodiment. Furthermore, with this configuration, when strong water is sprayed between the outer panel 30 and the adjacent exterior panel PF during rainfall or when washing the car, the inter-panel seal 55 flexes and elastically deforms at the constricted portion 58. This allows the abutment portion 56 to maintain a state in which it abuts against the end face of the extension portion 32, thereby achieving a higher seal between the outer panel 30 and the inner panel 20.

[0043] In other words, the inter-panel seal 55 blocks direct sunlight from penetrating into the inner panel 20 and the inside of the door D through the gap between the outer panel 30 and the exterior panel PF, and also prevents rainwater and the like from entering. This suppresses deterioration over time of the paint on the inner panel 20 and the inside of the door D, so that the required weather resistance can be fully achieved with simplified painting. In addition, simplifying the painting process will reduce carbon dioxide emissions during vehicle manufacturing, thereby contributing to mitigating or reducing the impact of climate change.

[0044] <Fourth embodiment> Next, a vehicle seal structure S4 according to a fourth embodiment will be described in detail with reference to FIG. In the description, the same elements as those in the first embodiment described above are given the same reference numerals, and duplicated descriptions will be omitted. The seal structure for a vehicle S4 of this embodiment differs from that of the first embodiment in the configuration of the panel seal portion 50. The panel seal portion 50 of this embodiment has a hollow seal 59 formed in a cylindrical shape with an elliptical cross section. In the sandwiched seal state, the hollow seal 59 is compressed in cylindrical shape and comes into close contact with the outer inner surface 30b, thereby sealing between the inner panel 20 and the outer panel 30. With this configuration, it is possible to achieve the same effects as in the first embodiment.

[0045] <Fifth embodiment> Next, a vehicle seal structure S5 according to a fifth embodiment will be described in detail with reference to FIG. In the description, the same elements as those in the first embodiment described above are given the same reference numerals, and duplicated descriptions will be omitted. The vehicle seal structure S5 of this embodiment differs from the first embodiment in the configuration of the panel seal portion 50. The panel seal portion 50 of this embodiment uses a sponge-like member made of foamed rubber such as EPT SEALER (registered trademark). In the sandwiched seal state, the foamed rubber of the panel seal portion 50 is crushed and comes into close contact with the outer inner surface 30b, thereby sealing between the inner panel 20 and the outer panel 30. With this configuration, it is possible to achieve the same effects as in the first embodiment.

[0046] In the above-described first to fifth embodiments, the panel seal portion 50 is configured to be arranged on the periphery of the inner panel 20 via a base portion 40 having an approximately U-shaped cross section, but this is not limited to such a configuration. For example, the base portion 40 may have a flat plate shape consisting of only the outer wall 41, and may be attached to the inner panel 20 using various means such as clips, bolts, double-sided tape, and adhesive (see FIG. 8). Even with this configuration, the same effects as those described above can be achieved. It is also possible to use various means such as clips, bolts, double-sided tape, and adhesives to install the panel seal portion 50 directly on the inner panel 20 without using the base portion 40 (see FIG. 9). Even with this configuration, the same effects as those described above can be achieved. [Explanation of symbols]
