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.

As shown in Fig. 1, a preferred embodiment of a sealing system for a window glass of the present invention is shown. The sealing system of the window glass comprises a windshield 2, a water tank 3 located below the windshield, and a profiled member 2. The profiled member 2 has a second support rib 28 with a bevel 27 and has a contact surface above it for connecting the upper outer side of the profiled member 2 with the inner side of the lower edge of the windshield 1. The profiled member 2 may be made of one or more materials each having a suitable hardness such as a polypropylene, a polyvinyl chloride, an acrylonitrile-butadiene-styrene copolymer, or the like, or a combination thereof. The profiled member 2 can have a reinforcing insert 21 to elastically support an elastic arm 22 in its lower region. The material of the insert 21 may be an aluminum strip or a steel strip of 0.2 mm to 0.4 mm thick. A baffle plate 26 made of a softer material is disposed in the curved transition zone between the intermediate portion and the lower portion.

As shown in Fig. 1, on the front side of the profiled member 2, the second support rib 28, which is formed as a wedge-shaped rib, has a slope 27 from which a seal member 23 is laterally projected. The seal 23 is secured to the ramp 27 by at least one inner surface. The seal 23 can be composed of a plurality of hard and soft components, for example, the harder member of the seal 23 and the bevel 27 are connected to maintain a tight fit, the softer portion and the upper edge of the water tank 3 and the lower edge of the windshield 1 The connection, the harder part and the softer part are fixed to each other by a convex recess (not shown). In this way, materials of different kinds or hardness are joined together at a soft and hard junction, or bonded by bonding. The seal 23 and the profiled member 2 can also be made in one piece.

As can be seen from the assembled state in the figure, the windshield 1 is in contact with the seal 23 at its lower edge in a force or shape connection. Here, the sealing member 23 is made of a soft material as a solid body, and its lower side is tightly fitted to the upper edge of the water tank 3. The soft material is preferably a thermoplastic elastomer, a sponge rubber or another suitable material. Of course, the sealing member 23 can also be made hollow. As can be seen from the figure, the sealing member 23 simultaneously extends to the outer surface of the windshield 1 and the water tank 3 and closely fits, as shown in FIGS. 2 and 3, of course. The sealing member 23 extends and closely fits to the outer surfaces of the windshield 1 and the water tank 3, respectively, and the principle and effect thereof are similar to the sealing member 23 extending toward the outer surface of the windshield 1 and the water tank 3, and the close fitting is similar. .

On the back side of the windshield 1, the profiled member 2 is fixed by an adhesive stack 29 which is clamped from above, and the adhesive stack 29 is placed flat on the vehicle body. The profiled member 2 is directly attached to the back surface of the windshield 1 by the contact faces above and below the contact zone 25. A shallow groove is formed in the contact area 25 at a small distance from the opposite side of the windshield 1, and the shaped piece can be provided with a row of holes or corresponding rows of holes in the corresponding contact surface of the contact area 25. Different hole shapes can also be considered. The adhesive pile 29, which has not yet hardened, can reach the back side of the windshield 1 through these holes. The contact surface of the windshield 1 and the profiled member 2 can be connected in a shallow groove by using a double-sided perforated adhesive layer 24, and if necessary, the adhesive can be filled into the shallow groove through the hole, so that the profiled member 2 The entire upper portion is almost entirely adhered to the back of the windshield 1.

The transition region from the upper region to the intermediate portion of the profiled member 2 is formed as a groove which engages the lower rear edge of the windshield 1 from the lower side, and the second support rib 28 connecting the groove is forward or outward with the inclined surface 27 The projections are recessed, and the lower side of the second support rib 28 is recessed rearwardly or inwardly in the form of a curved portion 31, the inner side of which corresponds to the baffle plate 26. The elastic arm 22 that is convex forward or outward is connected to the curved portion 31. The profiled member 2 engages a first support rib 32 of the water tank 3 from above with a resilient arm 22, wherein the first support rib 32, the second support rib 28 and the resilient arm 22 constitute an undercut of the bayonet. However, the insert 21, which generally conforms to the hook shape of the profiled member 2, can also be shorter than shown.

In summary, the sealing system for a window glass includes a profiled member 2, and the profiled member 2 can be fixed to the lower edge of the windshield 1 through a contact surface, and the profiled member 2 has a hook shape in cross section and has The elastic arm 22 is also provided with an insert 21 for reinforcement in the profiled member 2. The profiled member 2 is sealingly fastened to a recessed first support rib 32 of the water tank 3. The window glass sealing system further includes a sealing member 23 that closely fits between the lower edge of the windshield 1 and the upper edge of the water tank 3 and to the outer surface of the windshield 1 and/or the water tank 3. Extend and work closely together. The seal 23 can be coupled to the second support rib 28 by a bevel 27 to form an elastic clamping body and support between the lower edge of the windshield 1 and the first support rib 32. At least one inner surface of the seal 23 is integrally or fixedly coupled to the ramp 27, and the seal 23 is preferably an elastically deformable, wedge-shaped or rectangular donor. The profiled member 2 and the seal member 23 can be made of a combination material, such as in the form of a composite body that is soft and internal. The insert 21 can increase the elasticity. Preferably, the contact faces of the profiled members 2 have contact regions 25 which are offset from each other in height, and a portion of the contact regions 25 is provided with a layer of adhesive layer 24 which is perforated if necessary, for example a double-sided adhesive applied in the front groove. The adhesive tape can also be perforated. The baffle plate 26 contributes to the elastic bearing shear load, and a support rib (not shown) of a soft material projecting inwardly is provided on the profiled member to perform the same 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.
