Description

Technical Field

[0003]

[0001] The present invention relates to an attachment structure of a roof weather strip that is attached to a fixed panel and seals between an end portion of a movable panel in a roof of a vehicle having an opening provided with an openable movable panel and a fixed panel.

Background Art

[0002] In a roof of an automobile having an openable movable panel and an opening provided with a fixed panel, as an attachment structure of a roof weather strip that is attached to the fixed panel side and seals between an end portion of the movable panel, for example, those described in Patent Documents 1 to 3 are known. FIG. 4 shows the technique described in Patent Document 1. The roof device 100 includes a movable panel 120 that opens and closes an opening of the roof panel 110, and a roof weather strip 200 that is provided between an opening edge of the roof panel 110 and the movable panel 120 and seals between the opening edge and the movable panel 120. The opening edge of the roof panel 110 includes a flange portion 140 that extends vertically downward from the roof panel main body 130. The roof weather strip 200 has an attachment base portion 210 that encloses the flange portion 140. Further, a clamping portion 160 that clamps the attachment base portion 210 of the roof weather strip 200 is provided on a guide rail 150 that is attached to the roof panel 110 and supports the movable panel 120. By adopting the above configuration, the assembled roof weather strip 200 is stably held through the clamping portion, so that the reliability of the roof weather strip 200 can be improved.

[0003] Figure 5 shows the technology described in Patent Document 2. The roof weatherstrip 200 has a mounting base 210 attached to the tip of a fixed base panel 180 to which a fixed panel 170 is attached, and a sealing portion 190 that contacts the movable panel 120. The mounting base 210 has a panel engaging portion 230 that engages with the tip of the fixed base panel 180, and a rim engaging portion 250 that engages with a panel rim 240 attached to the tip of the fixed panel 170. The panel engaging portion 230 is formed on the lower side of the mounting base 210, and the rim engaging portion 250 is formed on the upper side of the mounting base 210. With the above configuration, the side of the mounting base 210 on the tip side engages with the tip of the fixed base panel 180 by the panel engaging portion 230, and the rim engaging portion 250 on the fixed panel 170 side of the mounting base 210 engages with the panel rim 240, so that both side ends of the mounting base 210 can be securely attached.

[0004] Figure 6 shows the technology described in Patent Document 3. The roof weatherstrip 200 has a first weatherstrip portion 270, a second weatherstrip portion 280, and a connecting portion 290 that integrally connects the first weatherstrip portion 270 and the second weatherstrip portion 280. Furthermore, a convex portion 320 is formed that protrudes above the connecting portion 290 and extends in the longitudinal direction to seal the space between the sliding roof panel 330 and the fixed roof panel 260. Double-sided adhesive tape 300 is attached to the lower parts of the first weatherstrip portion 270 and the second weatherstrip portion 280, and the roof weatherstrip 200 is attached to the base plate 340 by this double-sided adhesive tape 300. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2012-62023 [Patent Document 2] Japanese Patent Publication No. 2013-199143 [Patent Document 3] Japanese Patent Publication No. 2010-260394 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] In the roofs of automobiles with openings that include both movable and fixed panels, the interior height—one of the indicators of interior space, i.e., the maximum vertical distance from the flat floor to the ceiling lining near the center of the vehicle—is approximately 10 to 30 mm shorter compared to vehicles without movable panels on the roof. As a result, complaints have been reported, particularly from taller individuals, regarding insufficient headroom.

[0007] Furthermore, in electric vehicles (EVs), which have been rapidly expanding in recent years, batteries are often mounted under the floor. This means the floor is positioned higher, and consequently the seat is also moved higher, further reducing the head clearance for passengers. Therefore, in vehicles with a movable panel on the roof that can be opened and closed, the limited head clearance can become a significant problem.

[0008] Furthermore, from the perspective of reducing vehicle weight, it is important to use resin for the panels and to miniaturize the mounting area of ​​the roof weatherstrip. In addition, when attaching the roof weatherstrip to the resin panel with adhesive, degreasing and priming of the resin panel surface are necessary, resulting in poor workability during assembly. Moreover, with double-sided adhesive tape, deterioration of the tape can lead to peeling from the panel or roof weatherstrip, causing water leakage, and the detachment of the roof weatherstrip can cause panel malfunction. [Means for solving the problem]

[0009] To solve the above problems, the present invention of claim 1 provides a vehicle roof on which at least two panels are arranged, the first panel being a movable panel configured to open and close the roof opening, the second panel being a fixed resin panel fixedly positioned adjacent to the first panel either in front of or behind the vehicle, and the second panel end on the first panel side of the second panel being provided in the vertical direction of the vehicle, Panel 1A sharply angled inclined surface is formed from the side toward the bottom of the vehicle, and a housing is disposed below the second panel of the vehicle. A weatherstrip mounting portion is formed in the housing below the inclined surface, projecting toward the top of the vehicle. The roof weatherstrip has a mounting base with a roughly U-shaped cross-section and a hollow seal portion connected to the mounting base, and the mounting base has, A separate component from the hollow seal section A bulge is formed, and the mounting base is attached to the weatherstrip mounting section. The weatherstrip mounting portion and bulging portion are located below the vehicle on the inclined surface of the second panel in the vehicle's vertical direction. This roof weatherstrip mounting structure is characterized in that the hollow sealing portion abuts against the first panel, and the bulging portion abuts against the inclined surface of the second panel.

[0010] In the present invention of claim 1, an acute-angled inclined surface is formed from the first panel side toward the vehicle downward, a housing is disposed below the vehicle on the second panel, the roof weatherstrip has a mounting base with a substantially U-shaped cross-section and a hollow sealing portion connected to the mounting base, the mounting base has, A separate component from the hollow seal section A bulging portion is formed, and a weatherstrip mounting portion that protrudes upward from the vehicle is formed in the housing below the inclined surface. The mounting base is attached to the weatherstrip mounting portion, which improves workability during installation compared to when the roof weatherstrip is attached by adhesive, and eliminates problems caused by deterioration after installation by adhesive.

[0011] Furthermore, the formation of an inclined surface on the second panel creates a new space between the second panel and the end of the first panel, thus creating an area where the tip of the weatherstrip mounting portion does not interfere with the second panel and the first panel. As a result, the position of the mounting base can be moved upwards on the vehicle, and the interior height can be increased in a vehicle having an opening on the roof with an openable and closable movable panel and a fixed panel. Furthermore, since the second panel 12 is made of resin, its weight can be reduced.

[0012] Furthermore, since the hollow seal portion abuts against the first panel and the bulging portion abuts against the inclined surface of the second panel, it is possible to prevent water from entering the interior of the vehicle from between the first and second panels. The hollow seal portion may also abut against the inclined surface of the second panel.

[0013] Incidentally, although the first panel can be opened and closed, it is generally left in a closed state, that is, in contact with the hollow seal, for a long time. As a result, the ends of the hollow seal and the first panel may become stuck together. If the first panel is opened while the ends of the hollow seal and the first panel are stuck together, the hollow seal is pulled in the longitudinal direction of the vehicle. Consequently, the opening side of the roughly U-shaped cross-section of the mounting base that connects to the hollow seal expands, and if this expansion becomes large, the mounting base may come off the weatherstrip mounting part.

[0014] Even in the above case, since the bulging portion is in contact with the inclined surface of the second panel, when the first panel is opened while the hollow seal portion and the end of the first panel are fixed together, the mounting base is prevented from coming off the weatherstrip mounting portion, and the above-mentioned fixed state can be resolved.

[0015] Here, "movable panel" refers to a panel that can move in the front-to-back direction of the vehicle, enabling it to open and close an opening formed in the vehicle's roof. "Fixed panel" refers to a panel that is attached to the vehicle's roof and does not move in the front-to-back direction of the vehicle. Note that the fixed panel includes the movement of the movable panel side of the fixed panel upwards on the vehicle when the movable panel opens its opening.

[0016] Claim 2 of the present invention is the invention of Claim 1, wherein the weatherstrip mounting portion of the housing is a roof weatherstrip mounting structure formed with the upper part of the vehicle inclined toward the first panel side.

[0017] In the present invention as of claim 2, the weatherstrip mounting portion of the housing is formed with the upper part of the vehicle inclined toward the first panel, so that the length of the weatherstrip mounting portion in the vehicle's vertical direction can be shortened. As a result, the position of the mounting base can be moved further upward on the vehicle, and the interior height can be further increased in a vehicle having an opening on the roof with an openable and closable movable panel and a fixed panel.

[0018] Moreover, since the upper part of the vehicle is inclined toward the first panel side, the attachment property of the weatherstrip to the weatherstrip attachment part of the attachment base is improved. Claim 3 of the present invention is a mounting structure for a roof weatherstrip in which the bulge portion is formed in the hollow seal portion and connected to the first end on the bulge portion side, in the invention of Claim 1 or Claim 2.

[0019] Claim 4 The invention according to claim is an attachment structure of a roof weatherstrip in which a lip that abuts against the housing is formed at a connection portion between the attachment base of the hollow seal portion and the housing in the invention of claim 1 or claim 2.

[0020] Claim 4 In the invention according to claim, since a lip that abuts against the housing is formed at a connection portion between the attachment base of the hollow seal portion and the housing, when the first panel, which is a movable panel, is opened, water adhering to the hollow seal portion, when the water travels downward along the hollow seal surface or when the water bounces back downward, the water-stopping performance between the attachment base and the housing can be improved.

[0021] Moreover, when the first panel is opened with the hollow seal portion and the end portion of the first panel fixed, if the hollow seal portion is pulled toward the first panel side and a force acts in a direction in which the opening side of the substantially U-shaped cross section of the attachment base expands, the lip can suppress the expansion of the opening side of the attachment base by pressing against the housing.

[0022] Claim 5 The invention according to claim is in the invention according to claim 4 wherein the hardness of the bulging portion and the lip is not more than the hardness of the hollow seal portion.

[0023] Claim 5 In the invention according to claim, since the hardness of the bulging portion and the lip is not more than the hardness of the hollow seal portion, it is easier to deform than the hollow seal portion. In the bulging portion, when the attachment base is sandwiched between the inclined surface and the housing, it can be bent to securely fix the attachment base of the roof weatherstrip to the weatherstrip attachment portion of the housing. Moreover, the water-stopping performance between the inclined surface can be improved.

[0024] On the other hand, the lip flexes and contacts the housing, which improves the watertightness between the mounting base and the housing. [Effects of the Invention]

[0025] At least two panels are provided on the roof of the vehicle. The first panel is a movable panel configured to open and close the roof opening. The second panel is a fixed resin panel fixed adjacent to the first panel either in front of or behind the vehicle. At the end of the second panel on the side of the first panel, an acute-angled inclined surface is formed in the vertical direction of the vehicle, extending downward from the first panel. A housing is provided below the second panel. A weatherstrip mounting portion protruding upward from the vehicle is formed on the housing below the inclined surface. The roof weatherstrip has a mounting base with a substantially U-shaped cross-section and a hollow seal portion connected to the mounting base. A separate component from the hollow seal section A bulge is formed, and the mounting base is attached to the weatherstrip mounting section. The weatherstrip mounting portion and bulging portion are located below the vehicle on the inclined surface of the second panel in the vehicle's vertical direction. Since the hollow sealing portion abuts against the first panel and the bulging portion abuts against the inclined surface of the second panel, the workability during installation is improved compared to when the roof weatherstrip is attached by adhesive, and problems caused by deterioration after installation by adhesive can be eliminated.

[0026] Furthermore, the formation of an inclined surface on the second panel creates a new space between the second panel and the end of the first panel, thus creating an area where the tip of the weatherstrip mounting portion does not interfere with the second panel and the first panel. As a result, the position of the mounting base can be moved upwards on the vehicle, and the interior height can be increased in a vehicle having an opening on the roof with an openable and closable movable panel and a fixed panel. In addition, since the second panel 12 is made of resin, its weight can be reduced.

[0027] Furthermore, since the hollow seal portion abuts against the first panel and the bulging portion abuts against the inclined surface of the second panel, it is possible to prevent water from entering the interior of the vehicle from between the first and second panels.

[0028] Furthermore, since the bulging portion is in contact with the inclined surface of the second panel, even when the first panel is opened while the hollow seal portion and the end of the first panel are fixed together, the contact between the bulging portion and the inclined surface prevents the opening side of the substantially U-shaped cross-section of the mounting base from expanding, preventing it from coming off the weatherstrip mounting portion and releasing the fixed state. [Brief explanation of the drawing]

[0029] [Figure 1] This is a plan view of the vehicle's roof as seen from above. [Figure 2] This is a cross-sectional view of a roof weatherstrip in an embodiment of the present invention. [Figure 3] Figure 1 shows a cross-sectional view AA of the roof weatherstrip in an embodiment of the present invention, attached to a hishing located below the second panel, with the first panel closed. [Figure 4] This is a cross-sectional view showing a conventional configuration (Patent Document 1). [Figure 5] This is a cross-sectional view showing a conventional form (Patent Document 2). [Figure 6] This is a cross-sectional view showing a conventional configuration (Patent Document 3). [Modes for carrying out the invention]

[0030] Embodiments of the present invention will be described with reference to Figures 1 to 3. In the following, the front-rear direction of the vehicle 1 will be referred to as the "front-rear direction," and the upper and lower parts of the vehicle 1 in the height direction will be referred to as the "upper" and "lower," respectively. The width direction of the vehicle 1 will be referred to as the "width direction."

[0031] Figure 1 is a plan view of the roof 2 of vehicle 1, as seen from above. Vehicle 1 is a sedan-type automobile, and the roof 2 is divided into four panels in the front-to-rear direction. The first panel 11 is a movable panel, while the second panel 12, third panel 13, and fourth panel 14 are fixed panels, a type known as a panoramic roof (or panoramic roof). The first panel 11 and the third panel 13 are made of glass, and by moving the interior cover of the glass, it is possible to enhance the sense of openness inside the vehicle over a wide area and to bring light into the vehicle. Note that vehicle 1 is not limited to a sedan-type automobile, and the roof 2 is not limited to a panoramic roof type.

[0032] The first panel 11 is mounted so as to be able to open and close the opening 10. That is, the first panel 11 is mounted so as to be able to tilt up, with its rear portion rising using its front portion as a pivot point, and to slide in the front-rear direction. In the opening and closing operation of the first panel 11, a so-called outer sliding type is employed, in which the panel slides while remaining in the tilt-up position. The first panel 11 has a roughly rectangular annular first panel edge portion 11a made of polyurethane resin material along its periphery, which corresponds to the end on the second panel 12 side. The resin material of the first panel edge portion 11a is not limited to polyurethane.

[0033] On the other hand, the second panel 12 is located in front of the first panel 11 and is installed to close the front of the opening 10. The second panel 12 is configured to lift upward on the side of the first panel 11 when the first panel 11 moves backward in order to adjust the amount of air entering the vehicle. However, the second panel 12 may also be configured so that the side of the first panel 11 does not lift upward.

[0034] Figure 2 is a cross-sectional view of the roof weatherstrip 20. The roof weatherstrip 20 has a mounting base 21 and a hollow sealing portion 22 connected to the mounting base 21. The mounting base 21 has a substantially U-shaped cross-section, with a first vertical side portion 23 and a second vertical side portion 24 connected by a connecting portion 25. The first tip portion 26 of the first vertical side portion 23 protrudes on the opposite side from the second vertical side portion 24. Note that the first vertical side portion 23 may not have a first tip portion 26 and may have the same shape as the second vertical side portion 24. Furthermore, if there is a gap between the first vertical side portion 23 and the weatherstrip mounting portion 52 (Figure 3), which will be described later, a tongue-shaped lip or an arc-shaped rib may be formed on the inside of the first vertical side portion 23 and the second vertical side portion 24.

[0035] The hollow seal portion 22 is connected to the mounting base 21 at two ends, a first end 28 and a second end 29, and has a roughly D-shaped cross-section. The first end 28 is connected to the connecting portion 25 of the mounting base 21. The second end 29 is connected to the first vertical side portion 23 of the mounting base 21. The D-shape of the hollow seal portion 22 is above the first tip portion 26 of the mounting base 21 and bulges above the connecting portion 25.

[0036] The bulging portion 30 spans the second vertical side portion 24 and the connecting portion 25 of the mounting base portion 21, and is formed in an arc shape, bulging diagonally upward in the opposite direction to the hollow seal portion 22. The thickness of the bulging portion 30 at the connection point with the second vertical side portion 24 of the mounting base portion 21 gradually decreases toward the second tip portion 27 of the second vertical side portion 24.

[0037] Furthermore, the connecting portion 25 side of the bulging portion 30 is formed to connect to the first end portion 28 of the hollow seal portion 22. However, the connecting portion 25 side of the bulging portion 30 may be formed separately from the first end portion 28 of the hollow seal portion 22.

[0038] Near the second end 29 of the hollow seal portion 22, a tongue-shaped lip 31 is formed that extends downward in a convex shape, away from the first vertical side portion 23 of the mounting base portion 21.

[0039] The roof weatherstrip 20 is formed by extrusion molding, with the cross-section shown in Figure 2 being continuously formed. The material used for the roof weatherstrip 20 is ethylene propylene diene rubber (EPDM), with the mounting base 21 being made of solid material and the hollow seal portion 22, bulge portion 30, and lip 31 being made of sponge material. The hardness of the solid material is 60 or higher on the International Rubber Hardness (IRHD) scale. The specific gravity of the hollow seal portion 22 is between 0.4 and 1.0. In this embodiment, the hollow seal portion 22, bulge portion 30, and lip 31 are made of sponge material with the same hardness. It is desirable that the hardness of the bulge portion 30 and lip 31 be less than or equal to the hardness of the hollow seal portion 22, from the viewpoint of ease of bending when the bulge portion 30 contacts the inclined surface 40 (Figure 3) and when the lip 31 contacts the housing 50 (Figure 3).

[0040] Figure 3 is a cross-sectional view AA in Figure 1, showing the roof weatherstrip 20 attached to the housing 50 located below the second panel 12 and the first panel 11 closed. The second panel 12 in Figure 1 is made of resin. On the second panel 12, an acute-angled inclined surface 40 is formed on the second panel end 15 on the first panel 11 side, extending downward from the first panel 11 side. In this embodiment, the angle between the upper surface 12a of the second panel and the inclined surface 40 is 30 degrees.

[0041] The angle between the upper surface 12a of the second panel and the inclined surface 40 is preferably between 15 and 45 degrees. If the angle is less than 15 degrees, the length of the inclined surface 40 can be secured, but the strength of the end portion 15 of the second panel will be insufficient, which is undesirable. If the angle exceeds 45 degrees, the strength of the end portion 15 of the second panel will not be a problem, but it will be undesirable because it will be impossible to secure a space that allows for the effect of increasing the interior height, contact between the bulging portion 30 and the inclined surface 40, and a watertight effect between the first panel 11 and the second panel 12 by the bulging portion 30 and the hollow seal portion 22, while maintaining the same gap between the first panel 11 and the second panel 12 as before.

[0042] The housing 50 has a housing inclined portion 51 that is inclined downward by approximately 15 degrees in the direction of the first panel 11. The tip of the housing inclined portion 51 is bent at 90 degrees relative to the housing inclined portion 51 and extends downward. If the mounting base 21 is attached to the weatherstrip mounting portion 52, which will be described later, without forming the housing inclined portion 51, the housing inclined portion 51 may not have an inclination and may be parallel to the second panel 12. Also, the angle of inclination downward is not limited to 15 degrees.

[0043] Located in front of the tip of the housing inclined portion 51 and below the inclined surface 40 of the second panel 12, a weatherstrip mounting portion 52 is formed, protruding upward from the housing inclined portion 51 and inclined at approximately 5 degrees toward the first panel 11 from the perpendicular to the housing inclined portion 51. When combined with the inclination angle of the housing inclined portion 51, the angle of inclination of the weatherstrip mounting portion 52 toward the first panel 11 with respect to a line drawn vertically from the upper surface 12a of the second panel is approximately 18 degrees. The length of the weatherstrip mounting portion 52 is longer than the depth of the opening of the mounting base 21. The thickness of the weatherstrip mounting portion 52 is the same as the width of the opening of the mounting base 21. Note that the inclination of the weatherstrip mounting portion 52 from the perpendicular to the housing inclined portion 51 is not limited to 5 degrees.

[0044] As shown in Figure 3, when the mounting base 21 of the roof weatherstrip 20 is attached to the weatherstrip mounting portion 52 of the housing 50, and the second panel 12 is positioned above the housing 50, the bulging portion 30 bends and contacts the inclined surface 40 of the second panel 12. Also, the lip 31 bends and contacts the inclined portion 51 of the housing.

[0045] When the first panel 11 is closed, the hollow seal portion 22 of the roof weatherstrip 20 is pressed against the first panel edge 11a of the first panel 11 and deformed, causing the hollow seal portion 22 to come into contact with the first panel edge 11a of the first panel 11 and the inclined surface 40 of the second panel 12. However, since the watertight effect between the inclined surface 40 of the second panel 12 and the roof weatherstrip 20 is achieved by the bulging portion 30, the hollow seal portion 22 does not need to come into contact with the inclined surface 40 of the second panel 12.

[0046] As described in detail above, this embodiment provides the following effects. (1) In this embodiment, the roof weatherstrip 20 has a mounting base 21 with a substantially U-shaped cross-section and a hollow sealing portion 22 connected to the mounting base 21, and the mounting base 21 is attached to a weatherstrip mounting portion 52 formed in the housing 50, so that the workability during installation is improved compared to attaching the roof weatherstrip 20 by adhesive, and problems associated with deterioration after attachment by adhesive can be eliminated.

[0047] (2) In this embodiment, the hollow seal portion 22 abuts against the first panel 11 and the bulging portion 30 abuts against the inclined surface 40 of the second panel 12, so that water can be prevented from entering the interior of the vehicle from between the first panel 11 and the second panel 12. Also, since the bulging portion 30 abuts against the inclined surface 40 of the second panel 12, even when the first panel 11 is opened while the hollow seal portion 22 and the first panel edge portion 11a of the first panel 11 are fixed together, the contact between the bulging portion 30 and the inclined surface 40 prevents the mounting base portion 21 from coming off the weatherstrip mounting portion 52 and also relieves the fixed state.

[0048] (3) In this embodiment, the inclined surface 40 is formed on the second panel 12, creating a new space between the second panel 12 and the first panel 11. This creates a region where the tip of the weatherstrip mounting portion 52 does not interfere with the second panel 12 and the first panel 11. As a result, the position of the mounting base 21 can be moved upward, and the interior height can be increased in a vehicle having an opening on the roof 2 with an openable and closable movable panel and a fixed panel.

[0049] (4) In this embodiment, the weatherstrip mounting portion 52 of the housing 50 is formed with the upper part of the vehicle inclined toward the first panel 11, so that the vertical length of the weatherstrip mounting portion 52 can be shortened. Therefore, the position of the mounting base 21 can be moved further upward, so that the interior height can be further increased in a vehicle 1 having an opening in the roof 2 with an openable and closable movable panel and a fixed panel. In addition, since the upper part of the weatherstrip mounting portion 52 is inclined toward the first panel 11, the ease of attaching the mounting base 21 to the weatherstrip mounting portion 52 is improved.

[0050] (5) In this embodiment, the connecting portion 25 side of the bulging portion 30 is formed by connecting to the first end portion 28 of the hollow seal portion 22, so that the connection strength between the first end portion 28 of the hollow seal portion 22 and the connecting portion 25 can be increased.

[0051] (6) In this embodiment, a lip 31 is formed at the connection portion of the hollow seal portion 22 with the mounting base portion 21, which contacts the housing inclined portion 51 of the housing 50. Therefore, when the first panel 11, which is a movable panel, is opened, even if water adhering to the hollow seal portion 22 travels downward along the surface of the hollow seal portion 22 or splashes back downward, it is possible to prevent water from entering between the mounting base portion 21 and the housing 50. Furthermore, when the first panel is opened with the hollow seal portion 22 and the first panel edge portion 11a of the first panel 11 fixed together, if the hollow seal portion 22 is pulled toward the first panel 11 and a force is applied in a direction that expands the opening side of the substantially U-shaped cross-section of the mounting base portion 21, the lip 31 can resist the housing 50, thereby suppressing the expansion of the opening side of the mounting base portion 21.

[0052] (7) In this embodiment, the second panel 12 is made of resin, so it can be made lighter.

[0053] In carrying out the present invention, the invention is not limited to the embodiments described above, and various modifications are possible as long as they do not depart from the purpose of the invention.
