Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a vibration suppressing structure for a quarter window of a vehicle.
[0002]
[Prior art]
Some wagon-type vehicles are configured such that the window glass (window body) of the quarter window is opened (swinged) by a hinge at a predetermined opening degree outside the vehicle (see Patent Document 1). The window glass of this quarter window is supported by two hinges at the top and bottom of the front edge and the operation part at the rear edge. The operation unit operates the window glass between a closed position and an open position, and can be locked at the closed position.

JP-A-9-24732 [0004]
[Problems to be solved by the invention]
Such quarter windows have few supporting points, and the window glass vibrates due to the vibration of the vehicle body and the wind pressure that accompanies the running of the vehicle. It was.
[0005]
An object of this invention is to suppress generation | occurrence | production of an annoying noise by suppressing the vibration of such a window glass (window body).
[0006]
[Means for Solving the Problems]
According to the first aspect of the present invention, the window body is supported by the hinge portion and the operation portion with respect to the window frame on the side of the vehicle body, and the interior and exterior of the vehicle interior are separated by a sealing material interposed between the window frame and the window body. In a quarter window that is water-tightly sealed, the sealing material abuts annularly on the surface of the window body as a whole, and hinges are provided at two locations on the top and bottom of the window body. A light-impermeable coating is applied substantially along the window frame, and a predetermined mass body is placed on the coating between the hinge portions at an outer position of the annular contact portion on the window body surface via an elastic body. It is characterized by being fixed.
[0007]
Here, the window body is generally a glass plate, but may be a resin plate such as acrylic.
[0008]
According to the present invention, the combination of the mass body and the elastic body absorbs vibration by a known vibration damping function, and suppresses vibration of the window body. Therefore, it is possible to suppress the generation of annoying noise when the vehicle is traveling. In addition, since the mass body is fixed between the hinge portions arranged on the outer periphery of the annular contact portion formed by the seal material and provided with the opaque portion, the outer peripheral end of the seal material having a large amplitude. between the hinge portion can suppress the vibration, Ri more effective der, more mass is invisible from the vehicle outside, no problem that impairs the appearance by providing the mass. Moreover, the translucent coating can be used as it is without changing what is applied irrespective of the present invention.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
[0014]
1 to 4, reference numeral 2 denotes a vehicle body of a wagon type vehicle, and 4 denotes a window glass of a quarter window (corresponding to the window body in claim 1 ). Reference numeral 6 denotes a hinge portion provided at two positions above and below the front edge of the window glass 4, and 8 denotes an operation portion provided at the rear edge of the window glass 4. The quarter window in this embodiment is also configured to open and close by performing a so-called swing operation with the hinge portion 6 as the center of rotation, as in the prior art.
[0015]
In the vehicle body 2, a weather strip (seal material) 10 is fitted to portions 222 and 242 that define the window frame of the quarter window, and the weather strip 10 is formed in an annular shape along the window frame. Therefore, the weather strip 10 keeps the space between the window frame and the window glass 4 watertight. As is clear from FIG. 2, the hinge portions 6 and 6 are located outside the annular shape formed by the weather strip 10, and the operation portion 8 is located inside the annular shape.
[0016]
A light-impermeable coating 12 is applied to the peripheral portion of the window glass inside surface along the ring shape of the weather strip 10, and the internal structure of the weather strip 10, the hinge portions 6, 6, and the operation portion 8. Etc. are made invisible from the outside of the vehicle. In other words, it hides things that you don't want to see and improves its appearance.
[0017]
In FIG. 3, 22 indicates a quarter pillar and 24 indicates a rear pillar. As is well known, the hinge parts 6 and 6 are each composed of a hinge main body 64, a coupler (consisting of bolts and nuts) 66, and a molding 62. The operation part 8 is known as a handle 84, a link main body 86, and a fixing part. 82. Further, the fixing portion 82 includes sandwiching plates 822 and 824 and a rivet 826.
[0018]
The above is a conventionally known quota window and its peripheral configuration.
[0019]
The mass body 142 and the elastic body 141 constituting the main part of the present invention are collectively indicated by 14, and the mass body 142 is fixed to the surface of the coating 12 by adhesion via the elastic body 141. The vibration suppression portion indicated by 14 is long in the longitudinal direction on the front side of the weather strip 10 and is positioned between the hinge portions 6 and 6 at two locations on the top and bottom. Therefore, the vibration suppressing portion 14 is also hidden from the outside of the vehicle, and is considered so as not to impair the appearance.
[0020]
The vibration suppression unit 14 is known as a lightweight damping material, the elastic body 141 is made of a synthetic rubber adhesive, and the mass body 142 is made of an aluminum sheet. The total thickness of the elastic body 141 and the mass body 142 is about 1.5 mm.
[0021]
When the vibration suppression unit 14 is not provided in the above configuration, when the vehicle travels, the window glass vibrates due to the vibration of the vehicle body or the change of the wind pressure outside the window glass, and is 1 to 2 KHz in the vehicle interior under a predetermined condition. A certain amount of annoying noise is generated. This noise is generated because the window glass 4 vibrates. When the vibration suppression unit 14 is provided, the vibration of the window glass 4 is suppressed by a known vibration suppression function using a combination of a mass body and an elastic body, and generation of annoying noise of about 1 to 2 kHz is suppressed. The In particular, in the case of the above-described configuration, the vibration suppressing portion 14 is disposed at a position that extends relatively long forward from the position in contact with the weather strip 10 of the window glass 4 and between the upper and lower hinge portions 6. Vibration can be effectively suppressed at a portion that vibrates greatly. In addition, since the vibration suppression unit 14 is disposed in the painted portion around the window glass, the appearance is completely the same as a conventional quarter window in which the vibration suppression unit 14 is not installed. The performance confirmation experiment was performed at room temperature with the quarter window closed.
[0022]
As mentioned above, although this invention was demonstrated based on one embodiment, this invention is not limited only to this embodiment, Various embodiments can be taken.
