Traction type anti-kidnapping device for automobile

Abstract

A traction type anti-kidnapping device for an automobile solves the problems that in the conventional transmission mechanism, unbalanced loading is easily caused, an upper beam assembly unbalances to cause unstable lift, and the restriction on attacking people in the automobile is failed, and comprises an upper beam assembly, a lower beam assembly and a transmission mechanism assembly which are assembled at the bottom of a seat in the automobile. The technical key points of the traction type anti-kidnapping device are as follows: the transmission mechanism assembly adopts two groups of transmission mechanisms which are symmetrically arranged; two symmetrically arranged motors in each group of transmission mechanism respectively drive respective driving wheels to rotate and draw transmission ropes to drive sliding blocks to move towards sleeve guide sliding grooves, as a result, two upper supporting rods and two lower supporting rods which are symmetrically distributed on the upper beam assembly and the lower beam assembly synchronously extend and drive the upper beam assembly to be lift in a balanced way, and a seat cushion and the backrest of the seat form an oblique included angle. The stress of components is reasonable in distribution; limited space in the bottom of the seat in the automobile is fully utilized; the lift is light, convenient, flexible and stable; the use is safer and more reliable; the anti-kidnapping performance is further improved; and a driver is effectively protected from being attacked by people in the automobile.

Description

technical field [0001] The invention relates to a safety protection device for a vehicle, in particular to an improved traction-type anti-hijacking device for a car used to protect the driver from being attacked by people in the vehicle. Background technique [0002] Existing safety anti-hijacking devices for cars used to protect the driver from being attacked by people in the car generally adopt components such as isolation guardrails installed in the car to separate the driver from the people in the car to protect the driver. Some also use sound and light alarm devices to call for help. The applicant once aimed at problems such as the ineffectiveness of existing protective measures such as various sound and light alarms or isolation guardrails, and the fact that the life and property safety of drivers who leave the car cannot be truly protected, etc., successively designed the application publication number as The "anti-hijacking device for cars" of CN102862542A and the "...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a traction-type anti-hijacking device for cars, which solves the problem that the existing transmission mechanism is easy to produce partial loads, which makes the upper beam assembly unbalanced, causes lifting instability, and restricts the attackers in the car. Failure and other problems, the force distribution of its components is reasonable, and the limited space at the bottom of the seat in the car is fully utilized. The lifting is light, flexible, and stable, and the use is safer and more reliable. It further improves the anti-hijacking performance and effectively protects the driver from being attacked by people in the car.
