Background technique

At present, the window glass of an automobile is generally bonded to the opening of the automobile body by means of an adhesive. In order to be able to be bonded in place, it is often used to bond automotive glass with shaped parts to the vehicle. When bonding, first, an adhesive strip is adhered around the opening to which the window glass is to be attached, and then the window glass is bonded to the opening. A fitting flange is generally provided around the opening for bonding the adhesive strip so that the window glass is flush with the peripheral surface after installation. Since the manner in which the outer ring of the opening portion of the automobile is inclined is always caused by the assembly flange not being matched, the above object cannot be achieved. Therefore, the height of the inclined wall should be consistent with the thickness of the window and the adhesive. In a particular design, the edge of the window does not use a profiled part, and for manufacturing reasons, the size of the window and the size of the opening cannot be matched, resulting in an edge between the window and the edge of the car or the inclined wall. A groove is formed.

detailed description

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail in conjunction with the drawings.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view showing the structure of a preferred embodiment of an automobile glass having a shaped member according to the present invention. As shown in FIG. 1, the automobile has an opening portion having a fitting flange 3 and an inclined wall 4 around the opening portion. The automobile glass having a profiled member includes a main surface 1 mounted on the opening portion facing the outer surface of the vehicle body and a profiled member 2 filled around the main surface 1; the profiled member 2 is attached to the edge of the main surface 1 of the automobile glass, shaped The piece 2 is fixed to the edge of the main surface 1 by extrusion coating, pre-bonding or the like. The profiled member 2 may be a thermoplastic material, preferably an elastomer or a mixture of a thermoplastic elastomer and a thermoplastic rubber. The automotive glass can be either glass or transparent plastic. It is possible to design a single piece or at least a double layer of glass and/or transparent plastic.

The profiled member 2 includes a first bump 21, a connecting block 22 and a flexible extension end, the first bump 21 is in contact with the back surface of the automobile glass, and forms a right angle with the back surface of the automobile glass, and the connecting block 22 and the The first bumps 21 are connected and are parallel to the main surface 1 and located between the main surface 1 and the fitting flange 3. As shown, the profiled member 2 is only provided on one side of the automotive glass. Preferably, the profiled members 2 can also be separately/simultaneously disposed on the other three sides of the automotive glass.

The connecting block 22 is connected to a flexible extending end. The flexible extending end includes a second protrusion 221, a first sealing rib 222 and a second sealing rib 223. The second protrusion 221 is used for connecting the first sealing rib 222 and the second sealing rib 223. The first sealing rib 222 is for sealing connection with the edge 5 of the opening, and the second sealing rib 223 is sealingly connected with the main surface 1. The first sealing rib 222 is away from the automobile glass, and the second sealing rib 223 is at a position opposite to the first sealing rib 222. The second bump 221 for connecting the first sealing rib 222 and the second sealing rib 223 is about micro-protrusion with respect to the plane of the main surface 1 as shown, and has a triangular-like cross section, and connects the connecting block 22 at one point. The first sealing rib 222 and the second sealing rib 223 are respectively connected at two points.

Here, the connecting block 22 has no direct sealing and covering filling function, even if the connecting block 22 covers a part of the gap space; the connecting block 22 serves as a deformable supporting member to connect the flexible extending end (ie, the first sealing rib 222 and Second sealing rib 223). Thus the length of the connecting block 22 can be very small (for example 0.8 mm). In some embodiments, the connecting block 22 is a very small or narrow portion between the first bump 21 and the second bump 221, thereby forming a curved portion in a flat hinge manner, thereby realizing the curved portion The deformation support of the connection block 22.

At the time of mounting, the connecting block 22 is strongly deformed, and the bent portion performs the above-described functions. The second projection 221 is a bendable elastic member, and applying pressure to the second projection 221 provided in the gap between the inclined wall 4 and the fitting flange 3 ensures that the first sealing rib 222 is tightly close to the edge 5 of the opening portion. In cooperation, the second sealing rib 223 is in close fitting with the main surface 1 while the first sealing rib 222 and the second sealing rib 223 are both higher than the plane of the main surface 1. This design eliminates the need for additional seals, while applying pressure can effectively reduce the gap between the automotive glass and the mounting flange 3, avoiding dirt in the gap and noise generated when the vehicle is running.

However, the design of the connecting block 22 and the sealing ribs requires special consideration of the edge of the opening so as to avoid the damage or loss of function of the deformed strip 2 during use of the vehicle while achieving functionality. When the automobile glass having the profiled member is mounted, first the first sealing rib 222 abuts against the edge 5 of the opening portion, and then the second projection 221 is pressed until the second sealing rib 223 comes into contact with the main surface 1. An adhesive 6 is provided between the back of the car glass and the mounting flange 3 to ensure that the back of the car glass and the mounting flange 3 are connected while also ensuring a certain distance between the back of the car glass and the mounting flange 3. The first sealing rib 222 is designed as an elastic member having a small and narrow cross section, so that the contact between the first sealing rib 222 and the edge 5 of the opening portion can absorb more spatial errors caused by different automobile glasses. The first sealing rib 222 can be effectively sealed to the edge 5 of the opening. The second sealing rib 223 uses more hard material than the first sealing rib 222 and the connecting block 22, so that when the pressure is too large, the second sealing rib 223 and the first sealing rib 222 have sufficient hardness to not cause the shaped part 2 as a whole. Sag into the gap between the inclined wall 4 and the car glass.

In addition, as a preferred embodiment of the present invention, an auxiliary support member (not shown) may be disposed in the space 7, and the support member may be disposed on the connecting block 22 or the second bump 221, of course, as needed. Provided in other suitable positions, this arrangement can effectively prevent the entire profiled strip from sliding into the gap between the inclined wall 4 and the automobile glass due to external pressure, and of course, the connecting block 22 cannot be affected when disposed on the connecting block 22. Its own function.

The above description is only an embodiment of the present invention, and thus does not limit the scope of the patent of the present invention, and the equivalent structural transformation made by using the specification and the contents of the drawing of the present invention, or directly or indirectly applied to other related technologies. The fields are all included in the scope of patent protection of the present invention.
