Pillow type fireproof suit

Abstract

The basic structure of the pillow type fireproof suit is completely consistent with that of the invention patent (the application number is 2025207821281) claimed with the priority, and the pillow type fireproof suit comprises a split type fireproof suit body (a detachable jacket and trousers) and a containing cavity with the shape conversion function of a throw pillow, a waist pillow and a back cushion. The improvement of the invention is as follows: 1, a pillowcase detachable structure: pillowcases of a throw pillow, a waist pillow and a back cushion can be used independently, and can also be combined with the fireproof suit body to form an integrated carrier through a fixing assembly (the dismounting force is less than or equal to 15N), so that the multi-mode adaptation requirement of a vehicle-mounted scene is met; 2, according to a three-step folding protocol, a combined mechanism of spiral curling (the diameter is 15-18 cm), Z-shaped folding (the number of layers is 8-10) and magnetic attraction locking (the magnetic field intensity is larger than or equal to 400 mT) is adopted, and rapid form conversion from the fireproof suit to the vehicle-mounted pillow is achieved (consumed time is smaller than or equal to 18 seconds); the composite flame-retardant material system is composed of an aramid fiber 1414 blended outer layer (the oxygen index is larger than or equal to 32), an aerogel heat-insulation middle layer (the heat conductivity is smaller than or equal to 0.02 W / (m.K) at 800 DEG C) and a phase-change material inner layer (the latent heat is larger than or equal to 180 kJ / kg), and the fire-resistant time is prolonged to 12.8 seconds. On the premise of maintaining a priority patent basic structure, the vehicle-mounted adaptability and the emergency protection performance of the fireproof suit are remarkably optimized.

Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle safety equipment, and specifically to a fireproof suit with a split structure that can be folded into the forms of a pillow, a lumbar pillow, and a backrest. Its basic structure is exactly the same as that of the utility model patent (application number 2025207821281), forming a continuous innovation of this utility model. The embodiments and claims of this application exclude the headrest structure, and on this basis, a three-step folding protocol, a composite flame-retardant material, and a detachable pillowcase structure are newly added. Background Art

[0002] Existing on-vehicle fireproof equipment has the following technical defects: ‌Single form‌: Traditional fireproof suits are only used as protective clothing and cannot adapt to the multi-scenario requirements of on-vehicle spaces (such as temporary rest, lumbar support, etc.); ‌Low storage efficiency‌: The folding process relies on manual operation, taking more than 30 seconds, which is difficult to meet the requirements of emergency scenario response; ‌Limited material performance‌: A single flame-retardant material cannot balance heat insulation performance and wearing comfort (such as aerogel materials being prone to brittle fracture, and phase change materials being unable to stably adhere).

[0003] The utility model patent (application number 2025207821281) discloses a fireproof suit that can be folded into the form of a pillow, but it does not solve the following problems: (a) The folding process lacks standardized operation specifications, resulting in fluctuations in the form conversion efficiency; (b) The fixing method of the pillowcase and the clothing body is single, and it is impossible to flexibly switch between independent use and an integrated carrier; (c) The heat insulation layer and the phase change material do not form a synergistic effect, and the fire resistance limit only reaches 8.5 seconds. Summary of the Invention

[0004] The present invention aims to solve the following problems: (a) Improve the form conversion efficiency of the fireproof suit and establish a standardized folding process; (b) Achieve detachable and flexible adaptation between the pillowcase and the fireproof suit carrier; (c) Break through the performance bottleneck of single materials through a composite flame-retardant material system. Technical Solution

[0005] The core solution of the present invention includes: ‌(a) Three-step folding protocol‌: Through the parameter coordination of Z-type folding, palm folding, and magnetic attraction (100) locking strength (≥400 mT), the form conversion time is compressed to ≤18 seconds; (b)Detachable pillowcase structure: Based on the fixed component (removal force ≤ 15 N), the quick switching between the pillowcase and the clothing body is realized, meeting the dual needs of independent use or integrated carrier; (c)Composite flame-retardant material system: The outer layer of aramid 1414 blended fabric (oxygen index ≥ 32) provides basic flame retardancy, the middle aerogel heat insulation sheet (thermal conductivity ≤ 0.02 W / (m·K) @ 800 °C) inhibits heat conduction, and the inner layer of phase change material coating (latent heat ≥ 180 kJ / kg) absorbs the latent heat of phase change at high temperature. The three work together to increase the fire resistance time to 12.8 seconds. Technical effects

[0006] The present invention has the following advantages compared with the prior art: (a)Enhanced vehicle adaptability: By flexibly switching among three pillow forms, it adapts to the vehicle space in accordance with the GB / T 23120-2023 standard; (b)Improved emergency response efficiency: The standardized folding protocol reduces the time for form conversion by 40% (from 30 seconds to 18 seconds); (c)Breakthrough in protection performance: The composite flame-retardant material system extends the fire resistance time by 50% (from 8.5 seconds to 12.8 seconds).
