Description

Technical Field

[0001] This utility model belongs to the field of anti-fall technology, and specifically relates to an intelligent anti-fall suit airbag inflation device. Background Technology

[0002] The intelligent fall protection suit is an innovative protective gear that combines advanced technology to provide wearers with efficient safety protection. It uses high-precision sensors to monitor the wearer's movement in real time and can quickly activate an airbag inflation mechanism when a fall is detected, thus significantly reducing the risk of injury from falls. The airbag inflation device is a crucial component of the intelligent fall protection suit.

[0003] Chinese Patent Publication No. CN109268683B discloses a directional explosion and venting device for gas cylinders, which is fitted outside the sealed opening of a gas cylinder. The device includes a first igniter assembly, comprising a venting section with a vent hole and a detonating section for holding the igniter head. The venting section is fitted outside the sealed opening, and the vent hole connects the sealed opening to the external space. When the sealed opening is ruptured, the gas inside the cylinder rapidly flows into the external space from the venting section. The igniter head is secured inside the detonating section, extending out of the detonating section and close to the sealed opening. A limiting member is fitted over the igniter head, with one end abutting against the sealed opening to ensure that the shock wave is confined by the limiting member and directionally concentrated to rupture the sealed opening without spreading outwards, thus ensuring safety during the explosion of the sealed opening. The top of the detonating section has a pin hole for the pin of the igniter head to extend out, and the igniter head is electrically connected to a controller via the pin. The controller sends an ignition signal to cause the igniter head to explode and rupture the sealed opening.

[0004] However, the existing inflatable bladder inflation device has the following problems: 1. The gas cylinder stores high-pressure gas, which means that the cylinder opening needs to be sealed with a certain strength. In order to break through the seal, if the detonation force of the detonator is insufficient, it will affect the detonation effect. However, when the detonator with a large detonation force is used, it is easy to damage the detonator components and generate a lot of debris, and may even cause the device to be unable to release high-pressure gas to inflate the bladder.

[0005] 2. The vent is fitted over the sealing opening with a vent hole. The vent hole connects the sealing opening to the external space. The airbag is inflated through the vent hole. The airbag must avoid connecting to the vent hole at the detonation head pin to avoid affecting the transmission of the detonation signal, which would make the airbag installation inconvenient.
