Durable limiter used for vehicle

Abstract

The invention belongs to the technical field of vehicle door limiters, and particularly relates to a durable limiter used for a vehicle. The durable limiter comprises a mounting bracket, a limiting box, a rubber buffer block, a limiting arm and a clamping mechanism, wherein a limiting plane of a limiting bump at the lower side of the limiting arm is designed for different working states of an upper side compression spring and a lower side compression spring. While a lower side roller passes through the limiting plane, a limiting plate bears excessive compression elastic force, relative to thelower side compression spring, of the upper side compression spring, and a first gear is continuously kept still. On one hand, the limiting plate is used to ensure that compression amount of the upperside compression amount is higher than that of the lower side compression spring, and technical requirements, under different working states, of upper and lower compression springs are met, on the other hand, an upper side mounting plate is slightly downwards away from the limiting plate under force balance action after elasticity of the upper side compression spring is weakened while the limiting box is not matched with the limiting bump, so that a second rack gets out of the limiting box, and a normal follow-up regulating process is guaranteed.

Description

[0001] Technical field [0002] The invention belongs to the technical field of vehicle door stoppers, in particular to a durable stopper for vehicles. Background technique [0003] At present, when the vehicle is manufactured, a door stopper, a rubber spring stopper and a torsion spring stopper are installed on the car door. The car door stopper generally has the following two functions: one is the stopper arm Set 2-3 arc belts on the top, so as to form switch gears at the nodes of the arc belts and arc belts, so that the door has 2-3 positioning points during the opening and closing process; the second is to ensure that the car is on the specified ramp. It can ensure that the door stops at a certain fixed point and does not open or close by itself; The advantages of this structure are simple structure, low cost, small footprint and maintenance-free. The disadvantage is that the requirements for sheet metal are relatively high. If the strength of the hinge is not enough, th...

AI Technical Summary

Problems solved by technology

The disadvantage is that the requirements for sheet metal are relatively high. If the strength of the hinge is not enough, the door sinks, which may cause abnormal noise. After running for a period of time, the limit torque will decrease rapidly.

[0004] For the rubber spring type limiter, the door limiter of this structure generally has two or three gears, its maximum torque is about 35N.m, its length is generally about 60mm, and its maximum opening angle is generally below 70 degrees. After the test, the torque change is about 30%-40%; but the limit force loss is relatively large. After a long time of use, the elastic force of the spring or rubber will weaken, which will affect the overall performance of the vehicle.
