A car limit mechanism

Abstract

The invention belongs to the field of automobile door limiters, in particular to an automobile limit mechanism, which includes a limit arm, a buffer block, and a limit box mechanism, wherein one end of the limit arm is fixed on the vehicle body through a mounting seat hinged thereto Near the hinged part of the car door, the other end of the limit arm passes through the limit box mechanism fixed inside the car door; the present invention can be adjusted four times, and each adjustment is based on the previous adjustment. The pressure spring in the side expansion rod is further compressed, and the present invention can complete the adjustment and maintenance of the door stopper without dismantling the door, and its cost is relatively low; through the alternate adjustment of the two pressure springs in the present invention, the The invention effectively limits the opening of the car door and effectively prevents the opened car door from being closed under the action of wind or other external forces.

Description

technical field [0001] The invention belongs to the field of automobile door stoppers, in particular to an automobile stopper mechanism. Background technique [0002] The function of the door check (Door check) is to limit the degree to which the door can be opened. On the one hand, it can limit the maximum opening of the door to prevent the door from being opened too much. On the other hand, it can keep the door open when needed. For example, when the car is parked on a slope or the wind is blowing, the door will not automatically open. close. The common car door limiter is a separate drawstring type limiter, and some limiters are integrated with the door hinge, and usually have the function of limiting when the door is fully opened and half opened. The traditional door stopper has the advantages of simple structure, low cost and small occupied space. [0003] However, there is a door stopper in the form of pressure rollers and springs in the traditional car door stopper...

Problems solved by technology

[0003] However, there is a door stopper in the form of pressure rollers and springs in the traditional car door stopper. The two pressure rollers distributed symmetrically up and down are pressed against the limit position between the two pressure rollers under the pressure of the corresponding precompressed springs. The arm is squeezed to limit the opening of the door; the spring in this type of door stopper will be deformed and fatigued after repeated use for a long time, which will lead to insufficient preload of the spring on the pressure roller, which will affect its The limit effect on the door increases its maintenance cost
