Description

[Technical Field]

[0001] The present invention relates to a glass run for a vehicle. [Background technology]

[0002] For example, Patent Document 1 discloses a configuration that suppresses the phenomenon of the window glass swinging in the vehicle width direction when it is opened slightly more than when fully closed due to an increase in the reaction force that occurs when the interior auxiliary lip elastically deforms toward the interior of the vehicle compartment. This configuration suppresses contact between the interior side wall and the interior lip, thereby suppressing rattle noise caused by contact between the interior side wall and the interior lip. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-88031 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the configuration described in Patent Document 1, if the position of the windshield varies, the reaction force from the auxiliary lip on the inside of the vehicle increases, increasing the sliding resistance between the lip on the inside of the vehicle and the windshield, which may affect the sliding guide function.

[0005] In addition, although contact between the interior side wall portion and the interior lip is suppressed, contact between the interior lip and the interior auxiliary lip increases, which may result in rattle noise due to contact remaining.

[0006] In view of these problems, the present invention aims to provide a glass run for a vehicle that can suppress the generation of rattle noise that can occur when the glass vibrates while reducing the impact on the sliding guide function. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, a representative configuration of the present invention is a vehicle glass run that is fixed to a window frame of a vehicle door and guides the raising and lowering of glass, the vehicle glass run comprising an interior wall portion arranged on the interior side of the glass, an exterior wall portion arranged on the exterior side of the glass, a connecting portion connecting the interior wall portion and the exterior wall portion, and an interior lip and an exterior lip that extend from the interior wall portion and the exterior wall portion respectively towards the glass while approaching the edge of the glass and contact the glass so as to sandwich the glass, and is characterized in that at least one of the surface of the interior wall portion facing the lip, the surface of the interior lip facing the interior wall portion, the surface of the exterior wall portion facing the exterior lip, and the surface of the exterior lip facing the exterior wall portion is formed with an uneven portion whose ridge line extends in a direction that intersects obliquely with the window frame orthogonal direction that is orthogonal to the extension direction of the window frame. [Effects of the Invention]

[0008] According to the present invention, it is possible to suppress the occurrence of rattle noise that may occur when the glass shakes while reducing the impact on the sliding guide function. [Brief explanation of the drawings]

[Figure 6] 3(b) and 3(c) are a cross-sectional view and a partially enlarged end view of a vehicle glass run according to a modified example of the present invention, which correspond to FIG. 3(a). DETAILED DESCRIPTION OF THE INVENTION

[0010] One embodiment of the present invention is a vehicle glass run that is fixed to a window frame of a vehicle door and guides the raising and lowering of glass, the vehicle glass run comprising an interior wall portion arranged on the interior side of the glass, an exterior wall portion arranged on the exterior side of the glass, a connecting portion connecting the interior wall portion and the exterior wall portion, and an interior lip and an exterior lip that extend from the interior wall portion and the exterior wall portion respectively toward the glass while approaching the edge of the glass and contact the glass so as to sandwich the glass, and is characterized in that at least one of the surface of the interior wall portion facing the lip, the surface of the interior lip facing the interior wall portion, the surface of the exterior wall portion facing the exterior lip, and the surface of the exterior lip facing the exterior wall portion is formed with an uneven portion whose ridge line extends in a direction obliquely intersecting the window frame orthogonal direction that is orthogonal to the extension direction of the window frame.

[0011] According to the present invention, when the glass rises, it pushes against the interior lip and the exterior lip, causing the tip of the interior lip to slide toward the connecting portion while abutting against the interior wall, and the tip of the exterior lip to slide toward the connecting portion while abutting against the exterior wall. Frictional vibrations are generated in the vehicle glass run in a direction perpendicular to the ridges of the uneven portions. At this time, natural vibrations due to frictional vibrations are generated in at least one of the interior wall, interior lip, exterior wall, and exterior lip, which have uneven portions, in a direction oblique to the sliding direction between the lip and the side wall. The natural vibrations due to frictional vibrations are damped by the relative misalignment between the sliding direction and the vibration direction. As a result, rattle noises that may occur when the glass shakes can be suppressed while reducing the impact on the sliding guide function.

[0012] The diagonal intersecting direction preferably forms an angle of 20° or more and less than 90° with respect to the extension direction of the window frame. This configuration increases the damping rate of the natural vibration caused by frictional vibration. As a result, rattle noise that can occur when the glass shakes is more effectively suppressed while reducing the impact on the sliding guide function.

[0013] The height difference of the uneven portion is preferably equal to or greater than the width of the projections of the uneven portion. This configuration allows the uneven portion to easily deform during natural vibration caused by frictional vibration. This effectively creates a relative misalignment between the sliding direction and the vibration direction, suppressing the occurrence of stick-slip (chatter) between the interior wall portion and the interior lip, or between the exterior wall portion and the exterior lip. As a result, rattle noise that may occur when the glass shakes is more effectively suppressed while reducing the impact on the sliding guide function. [Example]

[0014] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Dimensions, materials, and other specific values ​​shown in these embodiments are merely examples for facilitating understanding of the invention and, unless otherwise specified, do not limit the present invention. In this specification and drawings, elements having substantially the same functions and configurations are designated by the same reference numerals to avoid redundant explanation, and elements not directly related to the present invention are not shown.

[0015] (First Example) FIG. 1 is a side view of the internal structure of a door 200 to which a vehicle glass run 100 according to a first embodiment of the present invention is applied, as seen from the vehicle compartment side. FIG. 2 is an end view of the vehicle glass run 100 of FIG. 1, as seen from above. In FIG. 1 and all other drawings, the longitudinal direction of the vehicle is indicated by arrows F (Forward) and B (Backward), the left and right in the vehicle width direction are indicated by arrows L (Leftward) and R (Rightward), and the up and down directions are indicated by arrows U (Upward) and D (Downward). The following description will be based on the door 200 disposed on the right side of the vehicle, but a similar configuration can also be applied to a door disposed on the left side of the vehicle.

[0016] 1, the door 200 has a door panel 208 and a sash 210 as a window frame fixed to the window of the door panel 208. The sash 210 is formed of, for example, metal. The sash 210 is arranged along the front, top, and rear edges of the glass 150 when the glass 150 is in the closed state of the window, and also extends from the front and rear edges of the glass 150 toward the bottom of the window.

[0017] 2, the sash 210 has an interior plate portion 212 arranged on the interior side of the vehicle, an exterior plate portion 214 arranged on the exterior side of the vehicle, and a connecting plate 216 that connects a base end 212a of the interior plate portion 212 to a base end 214a of the exterior plate portion 214. The sash 210 is formed with the interior plate portion 212, the exterior plate portion 214, and the connecting plate 216 to have a U-shaped cross section.

[0018] The interior side plate portion 212 has a step plate 212b. The exterior side plate portion 214 has a step plate 214b. The distance between the interior side plate portion 212 and the exterior side plate portion 214 is set to be wider on the connecting plate 216 side than the step plates 212b, 214b and narrower on the open side of the U-shaped cross section than the step plates 212b, 214b.

[0019] As shown in FIG. 2 , the door 200 also has a vehicle glass run 100. The vehicle glass run 100 is made of an elastic material. The vehicle glass run 100 is made of rubber. The vehicle glass run 100 may contain other thermoplastic elastomers or polymer resins. The vehicle glass run 100 is fixed inside the sash 210. The vehicle glass run 100 extends along the edge of the glass 150. The vehicle glass run 100 guides the glass 150 as it moves up and down.

[0020] 2, the vehicle glass run 100 includes an interior wall portion 102 disposed on the interior side of the glass 150, and an exterior wall portion 104 disposed on the exterior side of the glass 150. The vehicle glass run 100 also includes a connecting portion 106 that connects a base end 102a of the interior wall portion 102 and a base end 104a of the exterior wall portion 104.

[0021] As shown in FIG. 2, the leading end of the interior surface of the interior wall portion 102 and the leading end of the exterior surface of the exterior wall portion 104 are fitted between the interior plate portion 212 and the exterior plate portion 214.

[0022] 2, the vehicle glass run 100 also has an interior lip 112. The interior lip 112 extends from the leading end 102b of the interior wall portion 102 toward the glass 150 while approaching the edge of the glass 150. In other words, the interior lip 112 bends inward from the leading end 102b of the interior wall portion 102 and extends toward the connecting portion 106. The interior lip 112 faces the interior wall portion 102. The interior lip 112 is set to be smaller in dimension in the vehicle fore-and-aft direction than the interior wall portion 102.

[0023] The vehicle glass run 100 has an exterior lip 114. The exterior lip 114 extends from the leading end 104b of the exterior wall portion 104 toward the glass 150, approaching the edge of the glass 150. In other words, the exterior lip 114 bends inward from the leading end 104b of the exterior wall portion 104 and extends toward the connecting portion 106. The exterior lip 114 faces the exterior wall portion 104. The exterior lip 114 is set to have a smaller dimension in the vehicle fore-and-aft direction than the exterior wall portion 104.

[0024] The angle of the interior lip 112 relative to the interior wall 102 is set to be larger than the angle indicated by the two-dot chain line in Fig. 2 before the vehicle glass run 100 is fitted into the sash 210. Furthermore, the angle of the exterior lip 114 relative to the exterior wall 104 is set to be larger than the angle indicated by the two-dot chain line in Fig. 2 before the vehicle glass run 100 is fitted into the sash 210.

[0025] Therefore, when the vehicle glass run 100 is fitted into the sash 210 and the interior lip 112 and the exterior lip 114 are in contact with each other, the interior lip 112 is urged toward the exterior lip 114, and the exterior lip 114 is urged toward the interior lip 112. In other words, when the vehicle glass run 100 is fitted into the sash 210, the interior lip 112 and the exterior lip 114 have elastic forces that move them toward each other.

[0026] When glass 150 is present, interior lip 112 and exterior lip 114 each come into contact with glass 150, as shown by the solid lines. If glass 150 swings in the vehicle width direction in this state, interior wall 102 and interior lip 112 come into contact, or exterior wall 104 and exterior lip 114 come into contact.

[0027] The interior wall 102 has a protruding portion 102c that protrudes toward the interior of the vehicle. The exterior wall 104 has a protruding portion 104c that protrudes toward the exterior of the vehicle. The protruding portions 102c and 104c are located further back than the step plates 212b and 214b of the sash 210.

[0028] The interior wall portion 102 has an uneven portion 132 on a surface 102p facing the interior lip 112. The exterior wall portion 104 has an uneven portion 134 on a surface 104p facing the exterior lip 114. The uneven portions 132, 134 are formed with a V-shaped cross section. The uneven portions 132, 134 are formed by a plurality of fine unevennesses. Note that the uneven portions 132, 134 do not have to be formed finely. The uneven portions 132, 134 are formed so that the bottoms of the plurality of concave portions and the apexes of the plurality of convex portions extend parallel to each other. The uneven portions 132, 134 are formed so that the bottoms of the plurality of concave portions and the apexes of the plurality of convex portions extend linearly to form ridges.

[0029] The tip of the interior lip 112 is located within the range of the uneven portion 132 in the vehicle longitudinal direction. The tip of the exterior lip 114 is located within the range of the uneven portion 134 in the vehicle longitudinal direction. The interior lip 112 does not have an uneven portion on its surface 112p facing the interior wall 102. The exterior lip 114 does not have an uneven portion on its surface 114p facing the exterior wall 104.

[0030] Fig. 3(a) is a cross-sectional view taken along line AA of the vehicle glass run 100 of Fig. 1. Fig. 3(b) is a partially enlarged end view of Fig. 3(a). Fig. 4 is a cross-sectional view taken along line BB of the vehicle glass run 100 of Fig. 3(a). In the following explanation, the uneven portion 134 will be mainly described, but the same applies to the uneven portion 132. Figs. 3(a) and 4 show the glass vibration direction G1, the relative sliding direction G2, the vibration direction G3, the extension direction N of the sash 210, and the ridge direction S.

[0031] The glass vibration direction G1 is the direction in which the glass 150 vibrates when it vibrates in the vehicle width direction. The relative sliding direction G2 is the direction in which the exterior lip 114 slides relative to the exterior wall 104. The vibration direction G3 is the direction of natural vibration caused by friction that occurs in the interior wall 102 when the interior lip 112 slides relative to the interior wall 102.

[0032] The extension direction N is the direction in which the sash 210 extends, and can also be said to be the direction in which the sash 210 guides the glass 150. The ridge direction S is the direction of the ridges of the uneven portion .

[0033] 3(a) and 4 show the relative sliding direction G2 between the exterior lip 114 and the exterior wall portion 104. On the other hand, the drawings do not show the relative sliding direction between the interior lip 112 and the interior wall portion 102. However, the latter case is considered to be the same as the former, and the latter is omitted from the drawings.

[0034] 3(a) and 4, the ridge line of the uneven portion 134 extends in a ridge line direction S on the surface 104p. This ridge line direction S intersects obliquely with a relative sliding direction G2, which corresponds to a sash-orthogonal direction (window-frame-orthogonal direction) that is orthogonal to the extension direction N of the sash 210. In other words, G2 is both the sash-orthogonal direction and the relative sliding direction.

[0035] The uneven portion 134 has projections and depressions arranged alternately in a vibration direction G3 that is perpendicular to the ridge direction S. The vehicle exterior wall portion 104 has low rigidity in the direction in which the projections and depressions are arranged. Therefore, in the vehicle exterior wall portion 104, natural vibrations due to frictional vibrations are generated in the vibration direction G3.

[0036] The ridgeline direction S forms a predetermined intersection angle θ with respect to the extension direction N of the sash 210. In this embodiment, as shown in FIG. 4, the predetermined intersection angle θ is approximately 55°. However, this predetermined intersection angle θ may be other than approximately 55°, as long as it is 20° or more and less than 90°. In this case, 20° or more and less than 90° includes not only +20° or more and less than +90°, but also greater than -90° and less than -20°. Note that a larger angle difference between the ridgeline direction S and the extension direction N can better damp frictional vibration. For example, a difference in angle between the ridgeline direction S and the extension direction N of 20° or more and less than 90° can better damp frictional vibration than a difference in angle between the ridgeline direction S and the extension direction N of less than 20°.

[0037] 3(b), the height difference t of the concave-convex portion 134 is greater than the width p of the convex portion of the concave-convex portion 134. The smaller the width p of the convex portion of the concave-convex portion 134, the more the natural vibration caused by frictional vibration can be damped. Note that the height difference t of the concave-convex portion of the concave-convex portion 134 may be the same as the width p of the convex portion of the concave-convex portion 134.

[0038] Next, the process by which the glass 150 vibrates and rattles within the vehicle glass run 100 will be described. As shown in FIG. 3(a), the glass 150 vibrates in a glass vibration direction G1 (the rightward direction R or the leftward direction L of the vehicle width). As a result, the glass 150 pushes against the interior lip 112 and the exterior lip 114. Then, the tip of the interior lip 112 slides in the relative sliding direction G2 (toward the connecting portion 106) while abutting against the interior wall portion 102, and the tip of the exterior lip 114 slides in the relative sliding direction G2 (toward the connecting portion 106) while abutting against the exterior wall portion 104. Frictional vibrations are then generated in the vehicle glass run 100.

[0039] At this time, natural vibrations due to frictional vibrations occur in the vibration direction G3, which is oblique to the relative sliding direction G2, on the interior wall portion 102 on which the uneven portion 132 is formed, and on the exterior wall portion 104 on which the uneven portion 134 is formed. The natural vibrations due to frictional vibrations are damped by the relative misalignment between the relative sliding direction G2 and the vibration direction G3.

[0040] According to the configuration of this embodiment, it is possible to reduce the effect on the sliding guide function and suppress the generation of abnormal rattle noise that may occur when the glass 150 vibrates.

[0041] Furthermore, because the ridgeline direction S forms an angle of 20° or more and less than 90° with respect to the extension direction N, the damping rate at which the natural vibration caused by frictional vibration is damped increases. As a result, rattle noise that may occur when the glass 150 vibrates is more effectively suppressed. Note that, if the ridgeline direction S is 0° with respect to the extension direction N, the relative sliding direction G2 and the vibration direction G3 of the natural vibration caused by frictional vibration will be the same direction, and the phenomenon of damping due to a relative misalignment between the relative sliding direction G2 and the vibration direction G3 will be less likely to occur.

[0042] Because the height difference t between the concave and convex portions 132, 134 is equal to or greater than the width p of the convex portions of the concave and convex portions 132, 134, the concave and convex portions 132, 134 are easily deformed during natural vibration due to frictional vibration. This effectively creates a relative misalignment between the relative sliding direction G2 and the vibration direction G3, thereby suppressing the stick-slip phenomenon (chatter phenomenon) between the interior wall portion 102 and the interior lip 112 or between the exterior wall portion 104 and the exterior lip 114. As a result, rattle noise that may occur when the glass 150 vibrates is more effectively suppressed.

[0043] In the above embodiment, the configuration has both a configuration in which an uneven portion 132 is formed on the vehicle interior wall portion 102 and a configuration in which an uneven portion 134 is formed on the vehicle exterior wall portion 104, but this is not limited to the above embodiment and the configuration may have only one of the configurations.

[0044] (Second Example) 5 is a cross-sectional view corresponding to FIG. 3(a) showing a vehicle glass run 300 according to a second embodiment of the present invention. In the second embodiment, no uneven portion is formed on a surface 302p of the interior wall portion 302 facing the interior lip 312, and on a surface 304p of the exterior wall portion 304 facing the exterior lip 314. However, in the second embodiment, an uneven portion 332 is formed on a surface 312p of the interior lip 312 facing the interior wall portion 302. In addition, an uneven portion 334 is formed on a surface 314p of the exterior lip 314 facing the exterior wall portion 304.

[0045] In Figure 5, the relative sliding direction G2 is shown for the exterior lip 314 and the exterior wall portion 304, but is not shown for the interior lip 312 and the interior wall portion 302. However, the latter case should be considered in the same way as the former, and the latter has been omitted from the drawing.

[0046] The ridgeline of the uneven portion 334 extends in a ridgeline direction S that intersects obliquely with the relative sliding direction G2. The uneven portion 334 has alternating concave and convex portions arranged in a vibration direction G3 that is perpendicular to the ridgeline direction S. This configuration causes natural vibrations due to frictional vibrations to occur in the exterior lip 314 in the vibration direction G3, which is oblique to the relative sliding direction G2. Therefore, the natural vibrations due to frictional vibrations are damped by the relative misalignment between the relative sliding direction G2 and the vibration direction G3. As a result, the generation of rattle noises that may occur when the glass 150 vibrates can be suppressed. In this respect, the uneven portion 332 and the interior lip 312 are similar to the uneven portion 334 and the exterior lip 314.

[0047] While the above embodiment includes both a configuration in which the interior lip 312 is formed with the uneven portion 332 and a configuration in which the exterior lip 314 is formed with the uneven portion 334, the present invention is not limited to the above embodiment and may include only one of the configurations. Furthermore, the present invention is not limited to the above embodiment and may include a configuration in which the interior lip 312 is formed with the uneven portion 332 and the exterior lip 314 is formed with the uneven portion 132 of the interior wall 102 and the uneven portion 134 of the exterior wall 104 of the first embodiment.

[0048] (Variation) Fig. 6(a) is a cross-sectional view corresponding to Fig. 3(a) showing a vehicle glass run 500 according to a modified example of the present invention. Fig. 6(b) is a partially enlarged end view of Fig. 6(a). As shown in Fig. 6(a), an uneven portion 532 is formed on a surface 502p of the interior wall portion 502 facing the interior lip 512. An uneven portion 534 is formed on a surface 504p of the exterior wall portion 504 facing the exterior lip 514. These uneven portions 532, 534 have a plurality of rectangular unevennesses.

[0049] In Figure 6, the relative sliding direction G2 is shown for the exterior lip 514 and the exterior wall portion 504, but is not shown for the interior lip 512 and the interior wall portion 502. However, the latter case should be considered in the same way as the former, and the latter has been omitted from the drawing.

[0050] The ridgeline of the uneven portion 534 extends in a ridgeline direction S that intersects obliquely with the relative sliding direction G2. The uneven portion 534 has alternating concave and convex portions arranged in a vibration direction G3 that is perpendicular to the ridgeline direction S. As shown in FIG. 6(b), the height difference t between the concave and convex portions of the uneven portion 534 is equal to or greater than the width p of the convex portions of the uneven portion 534. With this configuration, natural vibrations due to frictional vibrations are generated in the exterior wall portion 504 in the vibration direction G3, which is oblique to the relative sliding direction G2. Therefore, the natural vibrations due to frictional vibrations are damped by the relative misalignment between the relative sliding direction G2 and the vibration direction G3. As a result, rattle noises that may occur when the glass 150 vibrates can be suppressed. In this respect, the uneven portion 532 and the interior wall portion 502 are similar to the uneven portion 534 and the exterior wall portion 504.

[0051] While the above-described modified example has both a configuration in which unevenness 532 is formed on interior wall portion 502 and a configuration in which unevenness 534 is formed on exterior wall portion 504, the present invention is not limited to the above-described modified example, and a configuration may be provided in which only one of the configurations is formed. Alternatively, the present invention is not limited to the above-described modified example, and a configuration in which rectangular unevenness is not formed on interior wall portion 502 and exterior wall portion 504, but is formed on both or one of interior lip 512 and exterior lip 514.

[0052] In addition, in the above-described modified example, the uneven portions 532, 534 are formed as a plurality of rectangular uneven portions, but this is not limited to the above-described modified example, and they may be formed as U-shaped uneven portions. It can also be said that a V-shaped uneven portion, as in the first embodiment, is easier to mold by die cutting than a U-shaped uneven portion, as in this modified example.
