Clamping prevention device of automobile door

Abstract

The invention discloses a clamping prevention device of an automobile door. The clamping prevention device comprises a linkage gear of the automobile door, the linkage gear is connected with a hinge of the automobile door, and the linkage gear can be driven in the rotating process of the automobile door; the linkage gear is fixedly connected with a linkage wheel through a linkage rod, and a steel rope is pulled by the leakage wheel; the steel rope is connected with the front segment of a brake box; a break gear is installed inside the brake box, and the linkage gear is connected with the brake gear through a gear chain; another steel rope is wound on the brake gear arranged inside the brake box, extends out of the brake hole through a hole and is connected with an integral brake groove. A pure mechanical mode is adopted, the structure is simple, the cost is low, and the feedback mode is flexible.

Description

technical field [0001] The invention belongs to the field of automobile safety equipment, in particular to a device capable of emergency braking when a car door encounters an obstacle in the closing process, and plays a role in protecting human limbs. Background technique [0002] At present, most cars on the market are equipped with anti-pinch devices for car windows. When the electric door and window glass is closed, it will automatically stop after encountering resistance, or change the glass upward stroke to a downward stroke, so as to prevent pinching. However, there are few devices that take into account the huge damage to human limbs during the closing process of the car door. If the car door clamps the hands due to improper operation, it will cause serious consequences, sometimes even causing serious consequences such as fractures and broken fingers. The phenomenon of car doors pinching people's hands is relatively common in car repair, car maintenance, car maintena...

AI Technical Summary

Problems solved by technology

[0004] However, the above inventions all rely on electronic means to prevent the car door from being pinched, and use the electrical signal of the sensor to give feedback after being processed by the computer. There are two problems in this way: one is that the cost is higher, and the other is that the accuracy of the electronic device is limited in long-term use. will drop later, and the product life cannot be better guaranteed
