Description

Technical Field

[0001] The utility model relates to the technical field of vehicle door stoppers, in particular to a vehicle door stopper with excellent slope-assisting performance. Background Art

[0002] The function of a door limiter is to limit the degree to which a door can be opened. On the one hand, it can limit the maximum opening of the door to prevent it from opening too wide. On the other hand, it can keep the door open when needed, such as when the car is parked on a slope or when there is a moderate wind, so that the door will not close automatically. Common door opening limiters are separate pull-strap limiters, and some limiters are integrated with the door hinge. They usually have a limiting function when the door is fully open or half open. They are used in the side doors of cars to limit and maintain the door's opening. In addition, they need to be able to maintain the door's opening after the car is parked on a certain slope. The main principle is that the slider slides on the limit arm with a concave and convex surface, compressing the spring to generate torque to meet the door's opening requirement.

[0003] The Chinese patent publication number is CN211473742U, and the authorization announcement date is September 11, 2020. It discloses a vehicle door stopper and a vehicle. The vehicle door stopper includes: a stopper arm, the stopper arm including a first side surface and a second side surface; a stopper cover including a first stopper plate, a connecting plate, and a second stopper plate, the first stopper plate and the second stopper plate being arranged opposite each other, a sliding hole being formed on the connecting plate, and the first end of the stopper arm passing through the sliding hole; the two ends of the first elastic component along the elastic direction respectively abut against the first stopper plate and the first side surface, the two ends of the second elastic component along the elastic direction respectively abut against the second stopper plate and the second side surface, and the second end of the stopper arm is limited to the side of the first elastic component and the second elastic component facing away from the connecting plate. The vehicle includes a vehicle door, a vehicle body, and a vehicle door stopper, the first end of the stopper arm being fixed to the vehicle body, and the connecting plate being fixed to the vehicle door. The vehicle door stopper and vehicle provided by the utility model reduce the assembly difficulty of the vehicle door stopper and reduce the weight of the vehicle door stopper.

[0004] The existing limiter only generates torque on two sides. When the car is parked on a larger slope, the slope-assisting performance of the limiter has certain limitations and cannot meet the slope-assisting needs of high-door heavy vehicles when parking on a large slope.

[0012] 1. This utility model device is provided with a first compression spring, a first slider, a second slider, and a second compression spring. The first compression spring applies a thrust to the first slider, which pushes the first slider into the gear pit of the limit arm and limits the position from the upper and lower directions of the limit arm. The second compression spring applies a thrust to the second slider, which pushes the second slider into the gear pit of the limit arm and limits the position from both sides of the limit arm.
