Description

Door stopper

Technical field

The invention relates to the manufacturing field of automobile door stoppers, in particular to a door stopper.

Background technique

As an indispensable transportation tool in the family, the automobile safety protection device has attracted more and more attention from consumers. The door stopper is an important part of the automobile safety protection device. It can make the door of the car when needed. Keep it open, such as when the car is parked on a ramp or when the wind is blowing, the door will not automatically close. However, it is very dangerous to open the door when the car is running, especially when the car is carrying a child in the rear. If the door lock is forgotten to close, it will be very dangerous to open the car door when the car is running. At present, there are only door locks and airbags in terms of door safety, but the safety locks need to be manually locked, and the airbags are only opened when the vehicle impacts. At this time, a reasonable mechanism needs to be designed to automatically restrict the vehicle during operation. The opening of the door.

At present, in the manufacture of automobiles, the door limiter is used to limit the opening degree of the door. On the one hand, it can limit the maximum opening of the door to prevent the door from opening too wide. On the other hand, it can keep the door open when needed, such as When the car is parked on a ramp or in normal wind, the door will not close automatically. The common door opening limiter is a separate pull-strap type limiter, and some limiters are integrated with the door hinge, and usually have a limit function when the door is fully open or half open. At present, when the working condition of the whole vehicle is bad, dust will enter the box body from between the door and the body seal, causing abnormal noise of the stopper. Therefore, it is particularly important to solve the problem of abnormal noise caused by dust entering the door stopper.

Summary of the invention

In view of the above technical problems, the object of the present invention is to provide a door stopper, which restricts the opening degree of the door by the stopper and the cable, and protects the stopper by the outer shell, and is provided with a locking dust-proof pad. The dust is blocked, and the dust collector is set to remove the dust inside the stopper, which solves the problem of abnormal noise caused by dust entering the door stopper. The technical scheme for realizing the present invention is as follows:

A vehicle door stopper includes a stopper, a stopper bracket is arranged at the left end of the stopper, a long bar is provided at the right end of the stopper, and a push rod is provided at the right end of the long bar, so A limit pin is provided on the right side of the push rod, a tension spring is provided on the right side of the limit pin, and a tension spring fixing plate is provided on the right side of the tension spring. A dust isolation pad is arranged on the shell, and the long bar is connected with the long bar fixing plate.

A further improvement of the present invention is that the tension spring fixing plate is fixed on the vehicle door by bolts, and is parallel to the upper surface of the long bar during installation.

A further improvement of the present invention is that: a position detection device is provided on the tension spring fixing plate.

A further improvement of the present invention is that the push rod is parallel to the position of the long-strip bar fixing plate.

A further improvement of the present invention is that the dust suction device and the push rod are on the same plane.

A further improvement of the present invention is that the limit pin and the tension spring are fixedly connected by welding.

A further improvement of the present invention is that the tension spring fixing plate and the tension spring are fixedly connected by welding.

A further improvement of the present invention is that the push rod is fixedly connected with the long gear rod.

The further improvement of the present invention is that: the outer layer of the tension spring is wrapped with a cladding layer.

Beneficial effects: the opening degree of the door is restricted by the stopper and the cable, and the stopper is protected by the shell, and the locking dust pad is set to block the dust, and the dust collector is set to remove the dust inside the stopper , To avoid abnormal noise caused by dust entering the door stopper.
