TECHNICAL FIELD

[0001] The utility model relates to the field of parts of passenger car, specifically is a stopper assembly with cylindrical limit arm. BACKGROUND

[0002] The door stopper assembly is used for connecting the door and the body, the current circulating stopper, the structure of limit arm adopts plane structure or rectangular structure design, so, in the process of door opening, the limit arm will deviate due to lateral force, resulting in the slider unable to run in the middle of the limit arm, and the door opening and closing process will appear serious jerk feeling. The lateral displacement of the limit arm causes the wear of the slider and the limit arm to be not centered, thereby causing the torque attenuation of the stopper assembly to be large, which cannot meet the customer's requirements. SUMMARY

[0003] The utility model aims at overcoming the above-mentioned defects, and provides a stopper assembly with cylindrical limit arm which is more uniform in stress and smoother in use.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized as follows:

[0005] A stopper assembly with cylindrical limit arm, comprising a limit arm, a cover and a bracket, the limit arm is a straight rod composed of multiple cylinders with different diameters, the cover is provided with a circular hole in the center and is sleeved on the limit arm through the circular hole, and the limit arm is provided with the bracket at one end.

[0006] The stopper assembly with cylindrical limit arm, three distance-distributed sliders are arranged in the circular hole in the center of the cover, push spring and baffle are arranged behind the sliders, so that when the cover slides on the limit arm, the sliders are tightly pushed on the limit arm by the action force provided by the push spring and baffle behind the sliders, and different damping feelings are generated when the sliders pass through the paragraphs with different diameters on the limit arm.

[0007] The stopper assembly with cylindrical limit arm, the cover is an annular part and is provided with three radially-distributed hollow legs, the sliders, push spring and baffle are arranged inside the hollow legs and extend from the inner wall of the circular hole of the cover, and the pin for connecting the cover with the body or the door is arranged in the axial direction of the leg.

[0008] The stopper assembly with cylindrical limit arm has the following advantages:

[0009] 1. The limit arm is adjusted from the traditional plane structure design to the cylindrical design, three circular-distributed sliders are arranged in contact with the surface of the limit arm, and the axial force provided by the three sliders can ensure that the limit arm does not deviate laterally in the process of door opening and closing, thereby improving the stability of the door opening and closing.

[0010] 2、Cylindrical limiting arm design with three circular array distribution of slider, can ensure the stable wear of slider in the durability process, improve the durability of the limit stop.

[0011] 3、Slider and rubber spring are all designed with cylindrical structure, simple and convenient installation. The cylindrical design can increase the cooperation precision with the surrounding parts, reduce the probability of abnormal sound. BRIEF DESCRIPTION OF DRAWINGS

[0015] The utility model is further illustrated by specific embodiments.

[0016] As shown in Figures 1-3 A limit stop assembly with cylindrical limiting arm, including limiting arm 1, cover 2 and support 3, limiting arm 1 is the straight rod of multiple different diameter cylinders, cover 2 is centrally provided with a circular hole and is sleeved on limiting arm 1 through the circular hole, and one end of limiting arm 1 is provided with support 3.

[0017] The limit stop assembly with cylindrical limiting arm, three distance-distributed sliders 4 are radially arranged in the circular hole in the center of cover 2, push spring 5 and baffle 6 are arranged behind slider 4, so that when cover 2 slides on limiting arm 1, slider 4 is tightly pushed on limiting arm 1 by the action force provided by push spring 5 and baffle 6 behind it, and different damping feelings are generated when slider 4 passes through different diameter sections on limiting arm 1.

[0018] The limit stop assembly with cylindrical limiting arm, cover 2 is an annular component and is provided with three radially-distributed hollow supports, slider 4, push spring 5 and baffle 6 are arranged inside the hollow supports and extend from the inner wall of the circular hole of cover 2, and pin 7 for connecting cover 2 with the vehicle body or door is arranged in the axial direction of the support.

[0019] The limit stop assembly with cylindrical limiting arm has the following advantages:

[0020] 1. The limit arm has been adjusted from a traditional flat structure to a cylindrical design. It is equipped with three circularly distributed sliders that contact the surface of the limit arm. The axial force applied by the three sliders to the limit arm can ensure that the limit arm has no lateral deviation during the door opening and closing process, thereby improving the stability of the door opening and closing.

[0021] 2. The cylindrical limit arm design is matched with three sliders distributed in a circular array, which can ensure stable wear of the slider during the durability process and improve the durability of the limiter.
