Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a concave-convex sliding door stopper with a secondary buffer structure. Background Art

[0002] In modern car design, sliding doors are widely used in various models, especially vans, SUVs and commercial vehicles. The advantage of the sliding door design is that it can be easily opened and closed in a narrow space, providing greater access and convenience. However, there are some problems with traditional sliding doors in actual use, which affect user experience and safety. First, traditional sliding doors are easily invaded by dust and sewage during long-term use, resulting in unsmooth opening and closing of the sliding door, or even failure. This not only affects the normal use of the vehicle, but also may bring safety hazards. Secondly, during the opening and closing process of the sliding door, due to the large angle between the body and the door, a strong collision may occur. This will not only cause damage to the vehicle, but also pose a threat to the occupants, especially when the vehicle brakes suddenly or opens and closes the door quickly. In addition, after long-term use, the limiter of the sliding door may fail to function due to wear and other reasons, further affecting the service life and reliability of the sliding door. The existing door limiter structure (publication number: CN209620936U) has the following inconveniences when used:

[0003] 1. Traditional sliding doors are easily invaded by dust and sewage during long-term use, which can cause the sliding door to open and close unsmoothly or even malfunction. This not only affects the normal use of the vehicle, but may also bring safety hazards;

[0004] 2. When the sliding door is opened or closed, a strong collision may occur due to the large angle between the vehicle body and the door. This will not only cause damage to the vehicle, but also pose a threat to the people inside the vehicle, especially when the vehicle brakes suddenly or opens and closes the door quickly;

[0005] 3. After long-term use, the limit device of the sliding door may fail to function due to wear and other reasons, further affecting the service life and reliability of the sliding door. Utility Model Content
