A limit device with adjustable limit force for automobiles

Abstract

The invention belongs to the field of car door stoppers, and in particular relates to a stopper with adjustable limit force for automobiles, which includes a stopper arm, a mounting base, a buffer block, and a stopper box mechanism, wherein one end of the stopper arm is hinged to it The mounting seat is fixed on the car body near the hinge of the car door, and the other end of the limit arm passes through the limit box mechanism fixed inside the car door; the two alternately moving racks respectively drive the corresponding wedge block B along the corresponding wedge. The inclined plane of block A is staggered relative to the corresponding wedge block A, so that wedge block A moves vertically to the limit arm direction, and the moving wedge block A further compresses the corresponding telescopic rod, so that the pressure spring in the telescopic rod is further compressed and released. Energy storage, so as to realize the adjustment of the compression amount of the pressure spring that is deformed and fatigued, and then ensure the pressing force of the pressure spring on the limit arm through the pressure wheel, and continue to effectively play the role of the door limiter on the door opening.

Description

technical field [0001] The invention belongs to the field of car door stoppers, in particular to a car door stopper with adjustable stop force. Background technique [0002] Cars are becoming more and more common in people's lives. Almost every family has their own car. With the development of the automobile industry, there have been many products for people to use cars better, such as door stoppers; they are currently widely used The special rubber spring type door stopper is fastened on the vehicle body through a mounting bolt, and the limit box is fastened on the car door through two mounting screws. When the door is opened, the limit box will move along the limit arm. Because there are different structures on the limit arm, the elastic rubber blocks will have different elastic deformations, so that people need to use different forces to close the door when opening the door. At each limit position point, it can play a limit effect on the car door. [0003] However, afte...

AI Technical Summary

Problems solved by technology

[0003] However, after the rubber spring door stopper has been in operation for a period of time, due to the deformation and fatigue of the internal rubber spring, the limit torque will decrease rapidly. It is necessary to disassemble the door and replace the rubber spring in the door to restore the limit The limit force of the stopper; the maintenance process is cumbersome and the maintenance cost is high; repeated disassembly of the door will cause certain damage to the door

[0004] In view of the disadvantages of the above-mentioned rubber spring door stopper, such as the rapid reduction of the limit torque caused by the fatigue of the internal rubber spring, and the cumbersome process of replacing the stopper, it is necessary to design a rubber spring that can be adjusted under the condition of internal rubber spring fatigue. The elastic force and then restore its limiting force to keep the limiter continuously and effectively limit the limit device for the door
