Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, specifically a sealing ring that fits into a car door. Background Technology

[0002] A car door sealing ring is a product used to seal a car door, making it difficult to open. It also serves to absorb shock, waterproof, soundproof, heat-insulate, dustproof, and secure the door. It is mainly used on car door panels and frames, side windows, front and rear windshields, engine hoods, and trunk lids. However, existing sealing rings still have certain defects in use, such as...

[0003] Existing sealing rings mainly adhere to the vehicle's sheet metal and doors through hollow abutment tubes. After long-term compression from the sheet metal and doors, the hollow abutment tubes are prone to deformation, which affects the adhesion and reduces the sealing effect, resulting in poor adhesion. Furthermore, existing sealing rings typically use a U-shaped thin iron sheet inside to clamp the sealing ring onto the vehicle's sheet metal. At the corners of the sheet metal, stress causes the inner side of the sealing ring to compress and the outer side to stretch, resulting in the collapse and deformation of the sealing ring's cavity, which also affects the adhesion effect.

The elastic strip has a cavity for rebound, and a rebound mechanism is provided in the cavity. The snap-fit ​​strip is also provided with a clamping mechanism.

[0007] The rebound mechanism includes: a diaphragm, a filling bladder, and epoxy resin. The inner wall of the cavity is connected to the diaphragm for separating the cavity space, and the inner wall of the cavity separated by the diaphragm is connected to the filling bladder for filling liquid.

[0008] Preferably, the filling bladder is filled with epoxy resin adhesive for assisting the rebound elastic strip, and the viscosity of the epoxy resin adhesive is 6000-8000 mPa·s.

[0009] Preferably, the clamping mechanism includes an iron sheet and a braided strip, wherein the snap-fit ​​strip is embedded with an iron sheet for clamping the vehicle sheet metal, and the iron sheet is made entirely of bent metal strips.

[0010] Preferably, the outer side of the iron sheet is connected with a woven tape for preventing the iron sheet from scattering, and the outer side of the iron sheet at the corner of the clamping strip is not provided with the woven tape.

[0011] Compared with the prior art, the sealing ring for the vehicle door has the advantages that when the elastic strip is extruded, the epoxy resin glue flows to assist the elastic strip to rebound, so that the elastic strip is tightly attached to the vehicle door, and the adhesion of the sealing ring is enhanced.

[0012] 1. The epoxy resin glue is stored in the filling bag, and when the elastic strip is extruded, the epoxy resin glue assists the cavity to rebound, so that the elastic strip is tightly attached to the vehicle door, and a plurality of filling bags prevent the adhesion of the sealing ring from being affected when one of the filling bags is damaged, thereby enhancing the adhesion of the sealing ring.

[0013] 2. The clamping strip is clamped on the vehicle panel by the iron sheet, and the bending and folding structure of the iron sheet reduces the stress at the corner of the vehicle panel, so that the sealing ring is attached to the corner of the vehicle panel, thereby reducing the stress at the corner of the sealing ring.
