Inertial safety device for automobile door handle

Abstract

The invention relates to an inertial safety device for an automobile door handle. The inertial safety device comprises a safety block device and a convex rod device, when the safety block device is atthe static position, a rotation path of a convex rod is receded by a groove in a safety block, and an automobile door can be opened; and after the safety block is subjected to impact action of high-speed inertia force to rotate, and when a pull handle drives the convex rod to rotate, the convex rod is blocked by the safety block, at the moment, the safety block is at the blocking position, and the automobile door is prevented from being opened. The blocking position range of the safety block is from the starting blocking position to the limit position, at the starting blocking position, the convex rod exactly cannot pass through the groove in the safety block when rotating, and the limit position is the rotation limit position of the safety block. The inertial safety device has the advantages of being high in functionality, safer, simple and compact in structure and low in cost.

Description

technical field [0001] The invention relates to the field of automobile door handles, in particular to a safety device for the automobile door handle. Background technique [0002] With the increasing number of cars, road traffic is quite busy, and traffic accidents occur frequently, people attach great importance to the safety of driving. Among various methods of improving driving safety, improving the safety of automobiles is undoubtedly the most effective measure. The door system is one of the important parts to ensure the safety of the vehicle. As a part of the door system, the car door handle is a key component to protect the safety of the people in the car when the car is collided, especially when it encounters a high-speed side collision. [0003] At present, the common car door handle structures are: pull-out type, flip-up type (also known as flip-out type or flip-up type), and hidden type. Traditionally, lift-type door handles generally lack additional safety dev...

AI Technical Summary

Problems solved by technology

Therefore, the above-mentioned inertial locking mechanism has the disadvantages of small working range, low safety and unreliable work.

[0005] On the other hand, the inertia part of the inertia lock body in the above-mentioned locking mechanism is separated from the blocking part, the shape is irregular, and it is not easy to process

The structure of the handle unlocking device is relatively complicated, and it is processed separately from the handle, and then assembled and connected

Therefore, the structure of the above-mentioned inertial locking mechanism is complicated, and the material and labor costs from parts manufacturing to assembly are relatively high.
