Abstract
Description
Technical Field
[0001] The present invention relates to a window glass device for a vehicle, the window glass device having a window glass movable between a closed position and an open position in a receiving channel, wherein, in the closed position, the window glass completely covers the corresponding window opening and is received in a glass receiving portion with a first edge region facing the roof of the vehicle, and is received by the receiving channel with a second edge region opposite to the first edge region, wherein, in the open position, the window glass at least partially opens the corresponding window opening, and wherein a sealing device seals the movable window glass relative to the receiving gap of the receiving channel. Background Technology
[0002] Various variations of window systems for vehicles with movable glass are known. If a vehicle with such a window system is driven in cold winter weather, especially in heavy snow or wet conditions, water and snow quickly accumulate on the outer channel guard of the sealing device. Here, the water accumulates and freezes on the sealing element of the outer channel guard. Subsequently, the movable window may no longer be able to be opened until the vehicle has fully warmed up and the frozen water thaws.
[0003] A sealing device for a vehicle window assembly of this type is known from DE 10 2014 018 528 A1. The window assembly includes a window glass movable in a receiving channel between a closed position and an open position. In the closed position, the window glass completely covers the corresponding window opening and is received in a glass receiving portion with a first edge region facing the vehicle roof, and is received by the receiving channel with a second edge region opposite to the first edge region. In the open position, the window glass at least partially opens the corresponding window opening. The sealing device includes at least one sealing element for sealing the movable window glass relative to the vehicle body or relative to a receiving gap in the receiving channel, and at least one vibration device for influencing the vibration of the window glass and / or the at least one sealing element. Furthermore, the sealing device includes at least one temperature sensor for detecting the ambient temperature of the vehicle. The vibration device can start operating according to the detected ambient temperature to eliminate obstruction to the window glass that may occur, particularly due to adhesion between the at least one sealing element and the window glass. Thus, for example, if the ambient temperature is particularly low, the sealing element may freeze to the window glass. It is also possible that the extremely high ambient temperature caused the sealing elements to stick to the window glass.
[0004] What may be considered a disadvantage here is that the published solutions for reliably opening windows, even at particularly low temperatures, are very complex and costly. Summary of the Invention
[0005] Therefore, the object of the present invention is to provide a window device for a vehicle having a movable window glass that can be reliably opened after the vehicle has stopped, especially at particularly low temperatures, with a simple and low-cost structure.
[0006] This objective is achieved by a window glass device for a vehicle having the following features.
[0007] To provide a window device for a vehicle with movable window glass, which can be reliably opened, especially at particularly low temperatures, with a simple and low-cost structure, the movable window glass has a wedge-shaped thickening at its outer side in a second edge region. When the vehicle is in motion, in the closed position of the movable window glass, the outer sealing element of the sealing device is sealed against the thickening. When the vehicle is parked, in the closed position of the movable window glass, there is a gap between the thickening and the outer sealing element of the sealing device.
[0008] In the following description, a window glass device for a vehicle is understood to include a device comprising a window glass movable between a closed position and an open position within a receiving channel. In the closed position, the movable window glass completely covers the corresponding window opening and is received in a glass receiving portion with a first edge region facing the roof. The movable window glass is received by the receiving channel with a second edge region opposite to the first edge region. In the open position, the window glass at least partially opens the corresponding window opening. A sealing device forms a seal between the movable window glass and the receiving gap of the receiving channel.
[0009] When the vehicle is parked, the embodiment of the window glass device for a vehicle according to the present invention prevents the outer sealing element from freezing to the outside of the movable window glass at particularly low temperatures by the gap or clearance between the outer sealing element of the sealing device and the thickened portion of the movable window glass. Since no contact area is formed between the outer sealing element and the movable window glass when the vehicle is parked, no ice wedges that would hinder the opening of the movable window glass will form there. Thus, the glass can be operated even when the outer channel guard of the sealing device is completely frozen in a wet state, because there is no contact with the movable window glass. However, due to the gap or clearance between the outer sealing element and the thickened portion of the movable window glass, a small amount of water may seep into the receiving channel. However, since the receiving channel is designed as a wet area, the seepage of water is acceptable. Conversely, to prevent wind noise, when the vehicle is in motion, the outer sealing element is against the thickened portion of the movable window glass.
[0010] In an advantageous design of the window glass device, compared to the closed position when the vehicle is in motion, the movable window glass can be lowered a predetermined distance to an intermediate position when the vehicle is parked in the closed position. This distance can be predetermined such that the movable window glass still completely covers the corresponding window opening in the intermediate position, and the upper edge area of the movable window glass is still received in the glass receiving portion. The window glass device according to the invention can be implemented particularly simply because when the vehicle is parked, the movable window glass is simply lowered slightly by the existing drive mechanism, and then simply raised slightly again when the vehicle is started. The movable window glass can be moved, for example, by a motor, which can be activated by at least one actuating element to cause the movable window glass to open or close automatically.
[0011] In another advantageous design of the window glass assembly, the thickening portion can be formed / molded, for example, at the second edge region on the outer side of the movable window glass. This means that the movable window glass can be manufactured on the outer side at the second edge region with this wedge-shaped thickening portion. Alternatively, the thickening portion can be designed as a separate component and connected to the outer side of the movable window glass at the second edge region.
[0012] In a particularly advantageous design of the window glass assembly, the thickened portion can be designed as a plastic component. Here, the plastic component can be bonded to the outer side of the movable window glass at the second edge region. The plastic component can, for example, be manufactured as a mass-produced item using plastic injection molding at a particularly low cost.
[0013] In another advantageous design of the window glass assembly, a thickened plastic component can replace the end section of the second edge region of the movable window glass, which is received by a receiving channel regardless of the window glass's position. Significant weight savings can be achieved by using this large plastic component to replace the movable window glass section.
[0014] In another advantageous design of the window assembly, the outer component of the body structure can form an external receiving channel boundary, while the inner component of the body structure can form an internal receiving channel boundary. Here, the outer and inner components of the body structure can each have two plate elements, which are connected to each other at a common connecting piece on their edge sides, for example by welding, bonding, riveting, or other suitable joining techniques. A sealing device can be positioned on this common connecting piece.
[0015] In another advantageous design of the window glass assembly, the sealing device may include an external channel strip with a U-shaped base, which is fitted onto an outer part of the vehicle body component, and an external sealing element may be disposed on the base. Alternatively, the sealing device may include an internal channel strip with a U-shaped base, which is fitted onto an inner part of the vehicle body component, and at least one internal sealing element may be disposed on the base. Here, regardless of the vehicle's operating state, at least one internal sealing element can abut against the inner side of the movable window glass in the closed position.
[0016] In another advantageous design of the window assembly, the body component can be designed as a door or side component. For example, movable window glass can be arranged on a door. However, movable window glass can also be another movable window glass of the vehicle. For example, in a convertible, movable window glass is typically arranged laterally behind the door in the longitudinal direction of the vehicle, and these movable window glass pieces are automatically moved from the closed position to the open position, especially when the convertible top is opened.
[0017] The features and combinations of features mentioned above in the specification, as well as the features and combinations of features mentioned below in the description of the drawings and / or shown separately in the drawings, can be used not only in the given combinations but also in other combinations or individually, without departing from the scope of the invention. Therefore, embodiments not shown or described in detail in the drawings can also be considered as included and disclosed by the invention; however, these embodiments can be learned and generated from the described embodiments through separate combinations of features. Attached Figure Description
[0018] An embodiment of the invention is shown in the accompanying drawings and described in detail below. In the drawings, the same reference numerals denote parts or elements that perform the same or similar functions. Wherein:
[0019] Figure 1 A schematic and partial cross-sectional view of an embodiment of the window glass device for a vehicle according to the invention in the closed position during driving is shown; and
[0020] Figure 2 Show Figure 1 A schematic and partial cross-sectional view of the window glass device for a vehicle according to the invention in the closed position during vehicle parking. Detailed Implementation
[0021] As from Figure 1 and Figure 2As can be seen, the embodiment of the window glass device 1 for a vehicle shown has a window glass 10 that can move between a closed position and an open position in the receiving channel 3. In the closed position, the window glass 10 completely covers the corresponding window opening and is received in the glass receiving portion 9 with a first edge region 12 facing the roof. The movable window glass 10 is received in the receiving channel 3 with a second edge region 14 opposite to the first edge region 12. In the open position, the window glass 10 at least partially opens the corresponding window opening. The sealing device 5 seals the movable window glass 10 relative to the receiving gap 4 of the receiving channel 3.
[0022] According to the present invention, the movable window glass 10 has a wedge-shaped thickened portion 16 on its outer side at the second edge region 14, which, when the vehicle is in motion, allows for... Figure 1 In the closed position shown, the external sealing element 5.2 of the sealing device 5 is sealed against the thickened portion, while in the parked state, the movable window glass 10... Figure 2 In the closed position shown, there is a gap A between the thickened portion and the external sealing element 5.2 of the sealing device 5.
[0023] from Figure 2 It can also be seen that, compared to the closed position when the vehicle is in motion, when the vehicle is parked and in the closed position, the movable window glass 10 descends a predetermined distance S to reach the intermediate position. From Figure 2 It can also be seen that the distance S is predetermined, so that the movable window glass 10 still completely covers the corresponding window opening in the middle position, and the upper edge region 12 of the movable window glass 10 is still received in the glass receiving part 9. From Figure 1 and Figure 2 The depth of the receiving chamber 9.1 of the glass receiving part 9 can also be seen. This glass receiving part is arranged, for example, at the upper edge of the door or the roof element. This depth is designed so that when the vehicle is parked, the upper edge of the movable window glass 10 is still clearly received and guided in the receiving chamber.
[0024] from Figure 1 and Figure 2 It can also be seen that the outer part 7A of the body component 7 forms the outer receiving channel boundary 3A, and the inner part 7B of the body component 7 forms the inner receiving channel boundary 3B. For this purpose, the outer part 7A and the inner part 7B of the body component 7 each have a first plate element 7.1A, 7.1B and a second plate element 7.2A, 7.2B that are preferably welded to each other at common connecting pieces 7.3A, 7.3B on the edge side. In the illustrated embodiment of the window glass device 1, the body component 7 is designed as a door. In an alternative embodiment (not shown), the body component 7 is designed as a side part arranged in the longitudinal direction of the vehicle behind the door.
[0025] from Figure 1 and Figure 2 As can also be seen in the illustrated embodiment, the first plate element 7.1A of the outer component 7A faces the receiving channel 3, while the second plate element 7.2A of the outer component 7A forms the exterior trim panel of the body component 7 designed as a door. The first plate element 7.1A and the second plate element 7.2A of the outer component 7A are connected to each other at a common connecting piece 7.3A, which forms the outer edge of the receiving gap 4 of the receiving channel 2. In the illustrated embodiment, the first plate element 7.1B of the inner component 7B, which is designed as a door, faces the receiving channel 3, while the second plate element 7.2B of the inner component 7B faces the vehicle interior. The first plate element 7.1B and the second plate element 7.2B of the inner component 7B are connected to each other at a common connecting piece 7.3B, which forms the inner edge of the receiving gap 4 of the receiving channel 2.
[0026] from Figure 1 and Figure 2 It can also be seen that the sealing device 5 includes an outer channel guard 5A with a U-shaped base 5.1A, which is fitted onto the outer part 7A of the vehicle body component 7, and an outer sealing element 5.2 is arranged on the base. In the illustrated embodiment, the outer sealing element 5.2 is designed as a sealing lip 5.2A formed on the base 5.1. For reinforcement or strengthening, a support core 5.4 is integrated into the base 5.1A of the outer channel guard 5A, which is exemplary designed as a U-shaped support bow 5.4A. Figure 1 and Figure 2 It can also be seen that the base 5.1A is covered on its outer side by a cover 6 designed as a decorative strip, which, in the illustrated embodiment, is fitted onto the base 5.1A of the outer channel guard 5A. Furthermore, the sealing device 5 includes an inner channel guard 5B with a U-shaped base 5.1B, which is fitted onto the inner part 7B of the body component 7, and at least one inner sealing element 5.3 is arranged on the base. In the illustrated embodiment, the two inner sealing elements 5.3 are each designed as sealing lips 5.3A formed on the base 5.1. For reinforcement, a support core 5.4 is also integrated into the base 5.1B of the inner channel guard 5B, which is exemplarily designed as a U-shaped support bow 5.4B. In the illustrated embodiment, regardless of the vehicle's operating state, the two inner sealing elements 5.3 abut against the inner side of the movable window glass 10 in the closed position of the window glass 10.
[0027] from Figure 1 and Figure 2As can also be seen, in the illustrated embodiment of the window glass assembly 10, the thickened portion 16 is designed as a separate component and is connected to the outer side of the movable window glass 10 at the second edge region 14. The thickened portion 16 is designed as a plastic component 16A and, in the illustrated embodiment, has a sliding ramp 16.1 for the external sealing element 5.2. Furthermore, the plastic component 16A is bonded to the outer side of the movable window glass 10 at the second edge region 14.
[0028] In an alternative embodiment of the window glass assembly 10 (not shown), a thickened portion 16 is formed at a second edge region 14 on the movable window glass 10.
[0029] In another alternative embodiment (not shown), the plastic member 16A forming the thickened portion 16 replaces the end section of the second edge region 14 of the movable window glass 10, which is received by the receiving channel 3 regardless of the position of the window glass 10. This significantly reduces the overall weight of the movable window glass 10. Therefore, in this embodiment, the plastic member 16A forming the thickened portion 16 can have a U-shaped receiving chamber, similar to the glass receiving portion 9, which receives the lower end of the movable window glass 10 in the fitted state and, for example, is additionally bonded to the movable window glass 10.
