Description

Technical Field

[0001] The utility model relates to the field of vehicle accessories, in particular to a glass sealing strip and a vehicle. Background Art

[0002] In vehicles, framed windows are usually lifting structures, which are set between the vehicle's external sheet metal and the vehicle's internal trim. At the same time, the window glass rises or falls in the gap between the two. For general framed windows, the sheet metal and the trim also form the window frame of the window glass, that is, the two sides of the glass are located in the gap between the sheet metal and the trim during the lifting process, and the glass is also embedded between the two when the value is highest.

[0003] The sealing strip is an indispensable part of the car window structure. The door glass sealing strip is installed on the edge of the sheet metal trim in the window frame and is attached to the side of the glass, playing an important isolation role, making the vehicle waterproof, soundproof and dustproof. At the same time, it also serves as a clamping guide to prevent the glass from shaking. In addition, the door glass sealing strip also plays a certain decorative role.

[0004] For commercial vehicle door glass with a larger span in height, the larger height dimension means that the glass plate has a greater weight and its upper end sways more, so a greater clamping force and a greater degree of fit are required, and the sealing strip needs a greater elastic deformation capacity. The existing technology is mainly designed for passenger cars, and the sealing effect is achieved by constructing two lips to interfere with the glass. However, the clamping force of the structure is usually designed to be small, which is difficult to meet the use requirements of commercial vehicles or other large vehicles, and is prone to cause glass vibration and abnormal noise. Summary of the invention

[0005] The utility model aims at solving the problem that the current glass sealing strip is difficult to meet the installation requirements of large-sized vehicle window glass, and provides a glass sealing strip with a larger fitting area and better sealing effect.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is a glass sealing strip, including a sealing strip body, the sealing strip body including a window frame connecting part, the cross section of the window frame connecting part is U-shaped, the outer side surface of the first side wall of the window frame connecting part is provided with a first bubble tube, the side edge of the first side wall close to the U-shaped opening is provided with an outward turning part, the outward turning part is provided with a second bubble tube, and the first bubble tube and the second bubble tube both extend along the length direction of the sealing strip body. The glass sealing strip adopted by this solution is installed on the window frame through a U-shaped groove structure. When the glass rises, the parallel first bubble tube and the second bubble tube contact the side of the glass at the same time. The contact area of ​​the sealing strip is increased, the bubble tube structure has a larger elastic deformation range, and a larger pressing force is provided through a larger elastic deformation, so that the glass clamping is more stable. At the same time, the outward turning part makes the second bubble tube naturally approach the glass direction, that is, it further has a larger pressing force. The sealing strip has a better sealing effect and is more suitable for large-area vehicle window glass.

[0007] Preferably, the inner side surface of the first side wall of the window frame connection part is provided with a plurality of raised strips, which extend along the length direction of the sealing strip body, and the inner side surface of the second side wall of the window frame connection part is provided with a plurality of mounting lips, which extend along the length direction of the sealing strip body. An inwardly facing raised structure is provided inside the U-shaped groove to make the sealing strip more firmly installed.

[0008] Preferably, the installation lip is inclined toward the bottom surface of the groove of the window frame connection portion. The deformation of the installation lip and the friction force form a non-return effect to prevent the sealing strip from being pulled out.

[0009] Preferably, a first cavity is provided in the second side wall of the window frame connection part, and the first cavity extends along the length direction of the sealing strip body; a second cavity is provided inside the groove bottom of the window frame connection part, and the second cavity extends along the length direction of the sealing strip body, so that the visible part of the sealing strip located outside has a better elastic touch and can prevent bumps.

[0010] Preferably, a flocking layer is provided on the outer convex surface of the first bubble tube relative to the first side wall, and a flocking layer is provided on the outer convex surface of the second bubble tube relative to the outwardly turned portion, so as to reduce the noise caused by friction with the glass.

[0011] Preferably, the sealing strip body is a rubber structure, a steel strip is embedded inside the sealing strip body, and the cross section of the steel strip is U-shaped, thereby improving the shape retention ability and installation stability of the sealing strip.

[0012] Preferably, the steel belt includes a base belt, which is arranged along the length direction of the sealing strip body, and a plurality of first comb teeth and a plurality of second comb teeth are respectively arranged on both sides of the base belt, the first comb teeth are located in the first side wall of the sealing strip body, and the second comb teeth are located in the second side wall of the sealing strip body. The bending ability of the steel belt is improved, and the bending installation of the sealing strip is convenient.

[0013] Preferably, the length of the first comb teeth is smaller than that of the second comb teeth, thereby improving the flexibility of the opening of the first side wall and facilitating the arrangement and deformation of the eversion portion and the second bubble tube.

[0014] Preferably, the sealing strip body is made of EPDM material.

[0015] On the other hand, the utility model also provides a vehicle, including a window frame, on which the above-mentioned glass sealing strip is installed, and the U-shaped groove of the sealing strip body is sleeved on the inner plate edge of the window frame. When the window glass is raised, the first bubble tube and the second bubble tube are in contact with the inner surface of the window glass.

[0016] It can be seen from the above technical scheme that the advantage of the utility model is that the two bubble tubes arranged in parallel provide two sealing areas with longer sealing widths for the door glass, so that the single-sided door glass sealing strip has a double-channel sealing effect, thereby achieving the purpose of improving the sealing effect of the sealing strip; the bubble tube design enables the glass sealing strip to have a larger elastic deformation, which can adapt to the larger normal displacement of the glass and has higher road condition adaptability; through the structural design of the sealing strip body, the sealing strip itself is stably and firmly installed on the edge of the window frame; at the same time, the vehicle provided by the utility model has the above-mentioned sealing strip, and the installation and sealing effects of the window glass are better.
