Pull-type anti-hijack device used for saloon car

Abstract

A pull-type anti-hijack device used for a saloon car solves the problems that an existing transmission mechanism is complex in structure, low in transmission efficiency, inconvenient to operate and the like. The pull-type anti-hijack device used for the saloon car comprises an upper beam assembly, a lower beam assembly and a transmission mechanism assembly, and the upper beam assembly, the lower beam assembly and the transmission mechanism assembly are arranged on the bottom portion of an assembling seat. The technical scheme includes that the transmission mechanism assembly comprise a motor which is fixed on a movable bottom plate, a pawl set and a drag component which is composed of a drive pipe, sliding blocks, transmission ropes, a drive wheel and a driven wheel. The sliding blocks which move along drive pipe guide sliding grooves are hinged with an upper beam and a lower beam through an upper main support rod and a lower main support rod. The drive wheel is fixed on a motor shaft. The transmission ropes which are twined on the drive wheel are fixed in the center holes of the sliding blocks through guidance of the driven wheel. The motor drives the drive wheel to drag the transmission ropes to drive the sliding blocks to move, the upper main support rod and the lower main support rod are enabled to stretch to drive the upper beam assembly to rise, a seat cushion and a back of the seat are enabled to form an inclined included angle to clamp and subdue a scoundrel. The pull-type anti-hijack device used for the saloon car is simple in structure, easy to manufacture, safe and reliable to use, convenient to operate, and further improves transmission efficiency and anti-hijack performance.

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 assembled at the bottom of a seat. Background technique [0002] Existing safety protection devices for vehicles generally adopt the method of setting sound and light alarms or installing components such as isolation guardrails in the car to separate the driver from the passengers to protect the driver. The applicant aims at problems such as the ineffectiveness of the existing protective measures such as various sound and light alarms or isolation guardrails, and the fact that the safety of the driver's life and property cannot be truly protected. "Anti-hijacking device for cars". It includes the upper and lower beam assemblies and the transmission mechanism assembly of the seat bottom assembled in the car, and the transmission with the transmission nut and the transmission gear driven by the motor of the transm...
