Circular hollow car door seat silica gel sealing ring and manufacture method thereof

Abstract

The invention discloses a circular hollow car door seat silica gel sealing ring and a manufacture method thereof. The section of the circular hollow car door seat silica gel sealing ring is in a hollow structure, the circular hollow car door seat silica gel sealing ring comprises a closed silica gel pipe body and a closed cavity, wherein the closed silica gel pipe body is formed by enclosing an adhering bottom surface, a buffer groove and a pressure-bearing surface, the buffer groove is positioned between the adhering bottom surface and the pressure-bearing surface, and the closed cavity is positioned in the closed silica gel pipe body. The circular hollow car door seat silica gel sealing ring can reduce the processing difficulty and the processing accuracy on the premise of ensuring the sealing property. When a car door is closed, the closed cavity plays a role of buffering an air bag and can release the impaction force of the car door and greatly lower the noise generated during the closing of the car door; and the buffer groove can ensure that the pressure-bearing surface has enough yielding space and the circular hollow car door seat silica gel sealing ring clings to the periphery of the car door, thereby achieving better sealing property.

Description

【Technical field】 [0001] The invention relates to a rubber seal for automobiles, in particular to a rubber seal for automobile doors. 【Background technique】 [0002] The car door is an important part of the car. For high-end cars, the door is not only required to be opened lightly, but also to be closed with good airtightness and low noise. In order to achieve the above requirements, the existing car door and the door frame use a silicone sealant. . Stick a silicone sealing strip on the door frame, and stick a water-retaining sealing strip on the inner side of the door. In high-end cars, the silicone sealing strips used in the door frame are all silicone tubes. Paste the strip-shaped silicone tubes along the door frame. During the sticking process, the two ends of the strip-shaped silicone tube cannot be well connected. In the actual use of this strip-shaped door frame sealing tube, although the sealing performance is better than that of the solid sealing strip, the impact ...

Problems solved by technology

Stick a silicone sealing strip on the door frame, and stick a water-retaining sealing strip on the inner side of the door. In high-end cars, the silicone sealing strips used in the door frame are all silicone tubes. Paste the strip-shaped silicone tubes along the door frame. During the sticking process, the two ends of the strip-shaped silicone tube cannot be well connected. In the actual use of this strip-shaped door frame sealing tube, although the sealing performance is better than that of the solid sealing strip, the impact force during the closing process of the door is relatively large. , the noise reduction effect is not obvious, and it is far from reaching the desired effect
