AI Technical Summary
After long-term use, the sealing performance of existing automotive sealing strips deteriorates due to rubber aging, compression deformation, and changes in assembly gaps, making it difficult to effectively prevent rainwater from seeping into the car.
The combination design of main chamber, sub-chamber, sealing lip and hooked lip is adopted. The main chamber buffers external force and rebounds to reset, the sub-chamber fills the gap, the sealing lip guides the water flow to slide, and the hooked lip intercepts the breaking water flow, forming multiple lines of defense to ensure the sealing effect.
Through a multi-layer sealing mechanism, the sealing state is stably maintained to prevent rainwater from seeping in, protecting the interior environment of the vehicle and avoiding mold growth and damage to electronic equipment.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-4The utility model provides a technical solution: an anti-water seepage automobile sealing strip, comprising a fixing seat 1 and a rubber base 2. The outer wall of the fixing seat 1 is provided with two layers of extension parts. The cross-section of the fixing seat 1 is in the shape of an "I", which effectively increases the fitting area with the mounting part of the vehicle body, enhances friction and adhesion, ensures installation stability, and avoids displacement during use. When subjected to frequent opening and closing extrusion of vehicle doors and windows and vibration impact of the vehicle body, it can evenly disperse stress and maintain its own shape stability. , maintain the sealed state, a sub-chamber 5 is opened at the bottom of the main chamber 4, the sub-chamber 5 assists the main chamber 4 in buffering, fills the possible microscopic gaps, and strengthens the sealing redundancy. The outer wall of the rubber base 2 is respectively extended with a sealing lip 6 at both ends. The top of the rubber base 2 is semicircular, and the cross-section of the main chamber 4 is semicircular and penetrates the upper end of the rubber base 2. The top surface of the sealing lip 6 is an inclined surface, and the highest point of the inclined surface of the sealing lip 6 is connected to one side of the outer wall of the rubber base 2, guiding the water when it contacts water The water flows down the surface and stays away from the infiltration path. Hook-shaped lips 7 are extended from the lower parts of the two ends of the outer wall of the rubber base 2. The cross section of the hook-shaped lips 7 is in the shape of a folded hook. The hook-shaped part of the hook-shaped lips 7 is arranged toward the outside of the rubber base 2. The hook-shaped lips 7 are located below the sealing lip 6. In daily use, even if a small amount of water breaks through the sealing lip 6, the folded hook-shaped structure uses a special geometric shape to "hold" the water flow and prevent it from penetrating inward. Together with the sealing lip 6, multiple waterproof checkpoints are formed to prevent water from seeping into the car windows.
[0021] During installation, the fixing seat 1 is placed on the window installation part. The two-layer extension of the outer wall increases the fitting area and enhances the friction to achieve a stable installation. In working state, when the window is closed, the rubber matrix 2 is squeezed, and the main chamber 4 smoothly deforms according to the pressure distribution law to buffer the external force. The auxiliary chamber 5 assists in filling the gap and maintaining the seal. In rainy weather, the water flow is guided to slide down through the inclined surface of the top surface of the sealing lip 6. If a small amount of water still breaks through, the hook-shaped lip 7 below uses the folded hook structure to "hold" the water flow. The two work together to build multiple lines of defense to prevent water seepage inside the window.
