Abstract

This invention discloses a six-buoy, purely mechanical, power-free automatic ejection rescue system for vehicles falling into water, aiming to solve the problems of easy failure, false triggering, and single-use of existing electronic control systems. The system includes six symmetrically arranged independent float ejection units on the vehicle body, a five-level purely mechanical anti-false triggering locking mechanism, a resettable, energy-accumulating ejection assembly, a high and low temperature resistant protective structure, and a high-toughness nylon rope multi-point locking and limiting mechanism. The five-level anti-false triggering mechanism achieves fully mechanical water-fall detection through a water level threshold cavity, immersion delay components, a gravity pendulum angle lock, a water pressure balance safety valve, and a vibration damping structure. After system triggering, each float is ejected under high-pressure gas and locked to the vehicle body at multiple points by nylon ropes, providing balanced buoyancy. This system achieves automatic water-fall detection, multi-point synchronous ejection, and reusability without a power source.

Description

Technical Field

[0001] This invention relates to the field of sampling device technology, specifically to a six-buoy, purely mechanical, power-free automatic ejection rescue system for cars that have fallen into water. Background Technology

[0002] When a car accidentally falls into water, doors and windows are often difficult to open due to water pressure and short circuits, making it difficult for occupants to escape and causing the vehicle to sink rapidly. Existing technologies sometimes use electronic sensors and control units to detect the water level and trigger airbags; however, electronic systems are prone to short circuits and failure after being submerged in water, resulting in insufficient reliability. Another type of simple mechanical triggering device frequently mis-triggers in everyday scenarios such as car washes, heavy rain, and bumpy roads, causing not only damage but also potential interference with driving safety. Furthermore, existing airbags are mostly disposable products, discarded after use, and often suffer from a single, unevenly distributed buoyancy point, leading to vehicle rollover or airbag detachment. In extreme high and low temperature environments, airbags and mechanisms made of traditional materials are prone to aging, cracking, or jamming, severely affecting their reliability for all-weather use. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a six-buoy, purely mechanical, power-free automatic ejection rescue system for cars that have fallen into water, thereby resolving the problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a six-buoy, purely mechanical, power-free automatic ejection rescue system for cars that have fallen into water.

[0005] It includes six independent float ejection units, a five-level purely mechanical anti-misfire locking mechanism, a resettable energy-accumulating ejection assembly, a high and low temperature resistant protective structure, and a high-toughness nylon rope multi-point locking and limiting mechanism.

[0006] The system consists of six sets of float ejection units, each containing an inflatable float. These units are symmetrically arranged on the left and right sides of the front bumper, the left and right sides of the center of the chassis, and the left and right sides of the rear chassis, forming a six-point balanced buoyancy support layout. Each float unit has an independent air passage and transmission path, ensuring that their operation does not interfere with each other.

[0007] The five-level purely mechanical anti-mistriggered locking mechanism is the core judgment module of the system. It completely eliminates circuits and sensors, relying on the linkage of purely mechanical components to achieve trigger judgment. This mechanism includes, in sequence: a water level threshold limiting cavity, which allows water to enter the subsequent mechanism only when the external water reaches a predetermined height; a water immersion delay component, which is a slow-release valve body. After the water enters, it must pass through its internal damping channel to achieve continuous immersion for 2-3 seconds before flowing to the next level, thereby filtering instantaneous water flow; a gravity pendulum angle lock, which includes a pendulum structure. Only when the vehicle body tilts at an angle of 12° or more and becomes unstable can the pendulum deflect to release the lock on the transmission path; a water pressure balance safety valve, which uses a water pressure stabilizing cavity design. Only when the vehicle body is stably submerged in water and the water pressure tends to be constant can the valve core be pushed to open the path; and a vibration damping limiting structure, which is a damping and shock-absorbing limiting block on the transmission path, used to absorb and filter driving vibrations and road bumps to prevent accidental unlocking. The above five levels of judgment are linked in sequence, and the ejection action is finally unlocked after all conditions are met.

[0008] The resettable accumulator launch assembly includes a spring-lock accumulator component and a high-pressure gas storage module. The spring-lock accumulator component pre-compresses the spring via a latch, which is linked to the launch mechanism of the float. After launch, the latch releases, and the user can manually press it to re-lock the spring and store energy. The high-pressure gas storage module is a standard high-pressure gas cylinder equipped with a quick-release interface. The cylinder has an inflation valve, which is activated when gas is released, inflating the float.

[0009] The multi-point locking and limiting mechanism is constructed from high-toughness, heat-resistant nylon ropes made of ultra-high molecular weight polyethylene, which are placed inside the cavity. For each float group, at least three rope fixing points are set: a front limiting rope, a middle load-bearing rope, and a tail anti-drift rope, forming a total of eighteen locking points across the six float groups. The rope lengths are precisely calculated to ensure that the floats tighten immediately after ejection and deployment, firmly securing them to their predetermined positions and preventing displacement or detachment due to water flow impact.

[0010] In addition, the system integrates high and low temperature protection design. The float is made of high-elasticity, heat-resistant composite airtight material with added antifreeze formula; moving parts are made of heat-resistant alloy steel or stainless steel combined with high-strength engineering plastics; and the seals use high-temperature resistant silicone-fluorine composite adhesive. The overall mechanism adopts a fully sealed cavity design to prevent water accumulation and sediment intrusion, ensuring stable operation of the system in a temperature range of -45°C to +90°C.

[0011] The beneficial effects of this invention are as follows:

[0012] First, the pure mechanical five-level anti-false triggering architecture accumulates judgments from five dimensions: water level, duration, posture, water pressure, and vibration, eliminating the problem of false start caused by daily scenarios such as car washing, splashing water, and bumps, and still operates reliably in underwater environments without electricity.

[0013] Secondly, the six-point symmetrical float layout provides balanced buoyancy for the entire vehicle, effectively preventing the vehicle from rolling over, tilting forward, or overturning, thus extending the escape window time.

[0014] Third, the system has a complete mechanical reset cycle capability. Core components such as ejection and delay can be quickly restored to standby state through manual operation. With replaceable gas cylinders, the system can be reused multiple times, significantly reducing usage and maintenance costs.

[0015] Fourth, by using a multi-point high-toughness nylon rope locking scheme and a fully sealed temperature-resistant design, problems such as float detachment, high and low temperature failure, and environmental corrosion are solved, ensuring the reliability and lifespan of long-term vehicle use.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example:

[0028] Example 1

[0029] Please see Figures 1 to 5 This embodiment provides a six-buoy, purely mechanical, power-free automatic ejection rescue system for cars that have fallen into water.

[0030] The six float ejection units 100 are arranged symmetrically, specifically: two units in the front bumper area, two units in the middle chassis area, and two units in the rear chassis area. Each unit contains an inflatable and deployable float 500. All units are installed to fit the contours of the vehicle body without excessively encroaching on the ground clearance.

[0031] In its normal standby state, the float 500 is folded and stored within the float storage cavity formed by the high-strength sealed protective shell. The core mechanism for the system to sense water impact and trigger is a five-level purely mechanical anti-false trigger locking mechanism 200.

[0032] When a vehicle accidentally enters a body of water and the water level gradually rises, water first flows into a water level threshold limiting cavity through a specific inlet. The inlet height of this cavity is calibrated to ensure that shallow water cannot enter. Next, water flows into the immersion delay component, where its internal tortuous damping channels force the water to flow slowly. This process lasts approximately 2-3 seconds, determining that the vehicle has been continuously submerged rather than briefly flushed. Simultaneously, the vehicle body gradually tilts under gravity. When the tilt angle reaches or exceeds 12°, the pendulum in the gravity pendulum angle lock overcomes deflection resistance and shifts, releasing the first mechanical lock. As the vehicle sinks completely into the water, the water level stabilizes, and the hydrostatic pressure acts evenly on the diaphragm or plunger of the water pressure balance safety valve, pushing it to move and release the second lock. Finally, after the vehicle vibration is damped by the water and meets the filtration conditions of the vibration damping limiting structure, the final barrier of the entire locking mechanism is released.

[0033] At this point, all five conditions for triggering the launcher assembly (300) are met, and the resettable charged launcher assembly is unlocked and triggered. (See also...) Figure 4 The latch 312 in the spring-loaded energy storage assembly 310 disengages under the drive of the pre-compression spring 311, simultaneously opening the high-pressure gas storage module 320. The inflation valve 323 on the high-pressure gas cylinder 322 is activated, and high-pressure gas is instantly injected into the six floats 500 via the quick-release interface 321 and pipes. The floats 500 burst through the weak areas of the protective shell, pop outwards, and rapidly inflate and unfold. At the moment of popping out, the high-tenacity nylon ropes pre-connected to each float are pulled out and tightened. Specifically, the front limiting rope, the middle load-bearing rope, and the rear anti-drift rope securely lock the inflated floats to the preset positions on the vehicle body from three directions, forming a stable eighteen-point locking network to prevent the floats from rolling, shifting, or detaching from the vehicle body under the impact of water flow.

[0034] Example 2

[0035] This embodiment, based on Embodiment 1, focuses on explaining the system reset operation procedure.

[0036] Once the lifesaving system has been activated and completed its mission, it can be quickly reset for reuse. The operator first clears away external mud and water. Then, the external protective cover is opened, and the ejected float 500 is manually folded neatly and pressed back into the storage cavity. Pressure is applied to the spring-loaded energy storage assembly 310 in the resettable energy storage ejection assembly 300, causing the latch 312 to re-engage with the unlocking mechanism, and the energy storage spring 311 to be compressed and recharged. Next, the depleted high-pressure gas cylinder 322 with the inflation valve 323 is loosened from the quick-release interface 321 and replaced with a brand new standard high-pressure gas cylinder and inflation valve assembly. The interface is then tightened to restore the air supply. Finally, wet components such as the water-delay component automatically return to their initial damping characteristics after air drying. The entire process requires no special tools and can be completed by a single person in approximately 3 minutes, restoring the system to standby status.

[0037] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
