Description

Touch method for airbag-serving airbag inflation circuit

Technical Field

The invention relates to air bag clothing, in particular to a touch method of an air bag inflating circuit of the air bag clothing.

Background

The use of the air bag clothes at present relates to a plurality of fields such as motorcycle drivers, high and low altitude operators and the like. The design of the air bag clothes is that air bags are clamped in the head and neck, waist, hip and other parts of the clothes, and the air bags are communicated with an inflatable tank which can be inflated instantly through an air pipe. The inflation tank is filled with compressed gas or substances capable of generating gas. One current method for triggering the inflator is to open the inflator to inflate the airbag by a certain pulling force, for example, the inflator on the airbag suit worn by a motorcycle rider is connected by a rope with one end sleeved on a handlebar and the other end fixed on the inflator. When the motorcycle is collided, the inflator tank is pulled open by the impact thrown away by the driver to rapidly inflate each airbag; another triggering method of the inflator is to use an electronic igniter, after the igniter triggers and detonates the opening of the inflator, the compressed gas or gas-generating substance in the inflator is triggered to generate a large amount of gas to rapidly fill each airbag, so as to protect the body, such as a wearable airbag suit (201010558820.4). The triggering of the detonation of such an inflator is first triggered by means of an acceleration sensor in the inflator circuit. The sensor presets a speed value, when the falling speed value sensed by the speed sensor reaches a preset value, a pulse signal is sent to the electronic detonating device to trigger the electronic detonating device, and the sensor is generally only suitable for high-altitude specialization. The speed sensor has strong technical performance, complex manufacturing process and high cost, and once the speed sensor fails, the detonation device cannot be started. The mode of the inflatable tank opened by the pulling force is that a place for fixing the rope, such as a motorcycle handle, is required, certain requirements are required on the direction and the force of the pulling force, and the mode is ineffective if the requirements are not met. In reality, a plurality of low-altitude operations, such as low-altitude power overhaul operation, low-altitude installation operation workers, clay bricklayers and other series of workers have no rope fixing positions and even have continuous mobile workplaces. In this operation, the airbag suit with the acceleration sensor is not applicable. How to solve the safety protection of these operators is a delicate subject. Therefore, the technicians develop corresponding safety measures, for example, in the patent of 'low altitude anti-falling vest' (201520335058.1), air bags are arranged at the front and the rear of the vest, and in case of emergency, an operator presses a chest air bag switch by himself. In an emergency, the worker is frightened to be dim, and the worker is easy to make mistakes to miss the protection, so the worker is not in practical use.

Disclosure of Invention

Aiming at the problems existing in the triggering of the air bag suit inflator pump and the defects of the detonation mode of the electronic detonation device, the using effect and the using range of the air bag suit are limited. The technical scheme of the invention is that the function of an acceleration sensor in the airbag inflating circuit of the airbag suit used at present is replaced by a switch 7 arranged in the airbag inflating circuit of the airbag suit and a switch 1 connected in series with the switch. The switch 7 in the air bag inflation circuit is arranged at the clothes-closing button of the air bag clothes, namely, a button on the left side of the clothes is buckled on a button on the right side of the symmetrical clothes, the button switch 7 in the circuit is switched on when the clothes are buckled, the button is switched off, and the circuit switch 7 is also switched off. The buttons on the two sides of the clothes are respectively embedded with wiring terminals and are respectively connected with circuits at the two ends of the clothes; the on-off device 1 in the circuit is a closed bottle-shaped device made of insulating hard materials, and a circle of conductor and lead wires 21, 22 and 23 are embedded at two ends and the inner sides of the middle section of the on-off device 1. The conductors and leads 21 and 23 at the two ends of the on-off device are respectively connected with the electronic ignition device 3 and the switch 7 in series through wires 2. A conductor and a lead wire 22 in the middle section of the on-off device 1 are connected with the battery 5 and the buzzer 6 in series and form a small loop through the switch 7; the on-off device 1 contains a small amount of conductive liquid 25, and when the on-off device 1 is laid flat, the conductive liquid is enough to connect conductors at two ends of the on-off device. The insulating part inner side surface 24 of the on-off device 1 is not infiltrated with the conductive liquid 25. The on-off device 1 is vertically fixed in the airbag suit. The principle of the technical scheme of the invention is that only the on-off device 1 in the airbag inflation circuit in the safety airbag suit is in an off state after the airbag suit is fastened. When the body of a user inclines or shakes seriously, the conductive liquid 25 in the on-off device also inclines, along with the increase of the inclination or shaking degree of the human body, the inclined conductive liquid 25 in the on-off device 1 firstly forms a small loop with the conductor at the middle section of the bottle-shaped device, the battery 5 connected with the lead 22 in series and the switch 7 of the buzzer 6, at the moment, the buzzer 6 buzzes to prompt the wearer of the air bag clothes to not continuously incline or shake the body, when the wearer of the air bag clothes continues to incline to be close to the horizontal level, the conductive liquid 25 in the on-off device 1 continuously inclines to the on-off device 1 to be connected with the electronic igniter 3 and the air inflation bottle 4 to form a loop, and the electronic igniter 3 immediately detonates the air inflation bottle 4 to inflate. The air inflation is completed instantly within 0.5 second, and if two air inflation bottles are arranged, the air inflation can be completed within 0.1 second. When the air bag suit is taken off, the snap fasteners of the air bag suit are unfastened, and the air bag inflation circuit of the air bag suit is in a disconnected state. The conductive liquid may be mercury, depending on the field of use of the airbag suit.
