Problems solved by technology

[0003] The sliders in conventional car door stoppers are generally rubber sliders, and the rubber sliders are prone to poor aging and cause the door to fail to open, and the rubber hardens in winter, making the door unable to open normally, which greatly affects the use of users.
In addition, the existing car door limiter also has the problems of short overall service life and poor fluency of door opening.

Embodiment

[0033] The following is based on Figure 1-5 A polyurethane spring slider type limiter according to an embodiment of the present invention is described in detail.

[0034] Such as Figure 1-3 As shown, the embodiment of the present invention discloses a polyurethane spring slider type limiter, which includes a limiter pull rod 1 , a limit case 2 , a fixed cover 3 , a fixed bracket 4 and a stopper 5 .

[0035] specific,

[0036] The fixed bracket 4 is fixed on the vehicle body, and the limit cover 2 and the fixed cover plate 3 are jointly fixed on the car door; one end of the limiter pull rod 1 is rotatably connected with the fixed bracket 4 through a limit rivet 6, and the other end is connected with the stopper 5 connect.

[0037] Such as figure 1 , 2, 4, and 5, the fixed cover 3 is fastened with the limit case 2 to form a box-shaped body with a cavity inside, and two groups of polyurethane slider springs 7 and 2 are symmetrically installed in the cavity of the limit cas...

Abstract

The invention discloses a polyurethane spring slide block stopper which comprises a stopper pull rod, a stopping housing, a fixed cover plate, a fixed bracket and a baffle plate. One end of the stopper pull rod is rotatably connected to the fixed bracket while the other end of the stopper pull rod is connected to the baffle plate. The fixed cover plate and the stopping housing are buckled to forma box-shaped body with a cavity inside, two polyurethane slide block springs and two I-shape-like slide block fixing seats are symmetrically mounted in the inner cavity of the stopping housing, and the stopper pull rod penetrates the box-shaped body and two slide block fixing seats in the box-shaped body and is slidably matched with the two slide block fixing seats. According to the polyurethane spring slide block stopper, the integral service life of a vehicle door stopper is prolonged correspondingly, and the smoothness of opening a vehicle door is further improved greatly. Close-assistant energy comfort degree and hand feeling quality of the stopper in the starting process are improved, and defects that in a conventional stopper, the slide blocks contract to become hard and rubber is poor in ageing for a long time are avoided, so that the quality of the whole vehicle door system is improved.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a polyurethane spring slider type limiter. Background technique [0002] With the continuous improvement of domestic / foreign automobile industry technology, consumers have higher and higher requirements for cars, and the perceptual experience of car doors among user groups has become more and more prominent. Domestic car companies have gradually begun to pay attention to the opening and closing of car doors in recent years. energy comfort and texture. [0003] The sliders in conventional car door stoppers are generally rubber sliders, and the rubber sliders are prone to poor aging and cause the door to fail to open, and the rubber hardens in winter so that the door cannot be opened normally, which greatly affects the use of users. In addition, the existing car door limiter still has the problems of short overall service life, poor fluency of opening the car door...
