Folding vehicle fire barrier

Abstract

The folding vehicle fireproof isolation frame is composed of a roof rod, a folding main body, a guide rail convex pipe, a directional moving wheel, a universal wheel, a fixing hole, a curved arc connecting frame and a composite fireproof layer. The folding vehicle fireproof isolation frame has a segmented nested folding effect and can easily expand the activity space of vehicle personnel. The isolation frame forms a protection space to park the vehicle, thereby providing a normalized fireproof and flame-retardant protection. The isolation frame can also be moved to stop the outward burning and spreading of the vehicle in case of fire, better protect the adjacent electric power-assisted vehicles, fuel vehicles, electric vehicles, new energy vehicles and building facilities, reduce property loss and environmental pollution, and bring more time for rescue. The device is used in underground parking lots, carports, garages, ground venues and outdoor parking lots for centralized parking of vehicles.

Description

Technical Field

[0001] This invention relates to the field of vehicle fire-fighting equipment, and in particular to a fireproof isolation frame for use in vehicles. Background Technology

[0002] With the increasing number of cars, car fires are also on the rise, especially in areas where cars are parked in concentrated areas. When one car catches fire or is ignited for other reasons, it can easily spread to neighboring vehicles. This is because most cars on the market do not have excellent fire-retardant properties and cannot stop the spread of fire. If there is also wind to help, it can cause a large-scale fire involving multiple cars, resulting in huge property damage and environmental pollution. It also adds psychological burden to car buyers.

[0003] Especially in parking lots, residential areas, gas stations and charging stations, LPG delivery stations, and highway service areas, the rapid spread of a car fire can cause unimaginable damage. With the increasing number of new energy vehicles parked in underground garages, the limited space makes it difficult for fire trucks to enter. When a vehicle catches fire, it cannot be extinguished in time, and nearby vehicles, equipment, and underground pipelines will also be destroyed. Therefore, the best course of action is to minimize losses, i.e., prevent the burning vehicle from igniting other adjacent vehicles or causing greater damage to the underground structure and its ancillary facilities.

[0004] With the increasing number of electric vehicles, their rechargeable batteries are chemically active and flammable. When the heat in the rechargeable battery continues to increase and thermal runaway occurs, this heat will accumulate and expand in a short period of time. If the heat and gas are not released in time, the battery may burn or even explode and splash. These combustions, which can reach temperatures of over 1,000 degrees Celsius, can also create new ignition points, damaging other vehicles and nearby objects. If people do not have time to escape, they are more likely to be injured.

[0005] At the time of this application, a full search of the published database using "vehicles and fire protection" as the abstract revealed an application with publication number [222841446U] for a fire-resistant isolation device for automobiles. The description states that its structure consists of a frame, fireproof cloth, and left and right telescopic units. The frame is equipped with fire extinguishing units, including connecting pipes and water guns. Its optimal application environment is its own parking space; it is not effective in centralized parking areas, especially due to difficulties in connecting with the site's fire protection facilities. The frame and mostly folding design result in numerous casters, which is not conducive to expanding the movement space in multiple directions for the vehicle and adjacent vehicles and personnel in centralized parking areas. A similar application with publication number [213884812U] for a manually movable telescopic fireproof cover for electric vehicles describes a design with both omnidirectional brake wheels and directional wheels on the folding frame, suitable for protection in independently parked vehicle locations. For planned parking spaces, there is freedom to expand the front and rear space, but the usable space on both sides is not easy to expand. There is insufficient space to expand the activity space in multiple directions when the vehicle and adjacent vehicles and personnel enter and exit. The connection between the horizontal roof pole and the main body of the folding frame is prone to rainwater accumulation. Summary of the Invention

[0006] To address the aforementioned issues, this invention proposes a foldable vehicle fireproof isolation rack. This rack isolates and protects the space where vehicles can be parked, providing a standard protective measure. It can also be moved to prevent fires from spreading outwards from vehicles in the event of a fire, thus better protecting nearby vehicles and buildings, reducing property damage and environmental pollution, and giving rescue teams more time.

[0007] The technical solution of this invention is as follows: A foldable vehicle fireproof isolation frame comprises a roof pole, a folding body, a guide rail convex tube, directional moving wheels, universal wheels, fixing holes, a curved connecting frame, and a composite fireproof layer. Its features include: the guide rail convex tube is a three-section sliding nested assembly; the directional moving wheels connected to the folding body move directionally within the guide rail convex tube; universal wheels are installed at the bottom of the guide rail convex tube; the universal wheels limit the movement of the guide rail convex tube during forward sliding nesting; and the roof pole is connected and fixed to the folding body using a curved connecting frame.

[0008] The folding body is a single movable assembly.

[0009] The directional moving wheel is confined within the convex tube of the guide rail, and a baffle plate is provided at the front end to prevent it from detaching.

[0010] The directional casters and casters are high-temperature resistant and flame-retardant rollers, such as fire-resistant phenolic rollers, alloy rollers, or all-steel load-bearing rollers.

[0011] The guide rail convex tube is preferably made of medium carbon steel, with a melting point exceeding 1500 degrees Celsius, a flame resistance of around 1000 degrees Celsius, and moderate toughness and strength.

[0012] The guide rail convex tube of the isolation frame is composed of at least three sections.

[0013] The purpose of setting up a three-section nested combination structure is that, for a vehicle that is close to five meters long, the door frame positions on both sides of the driver's side are basically at the center of the vehicle's length. In addition, there is an extra half meter of space to move backward to accommodate getting out of the vehicle. Therefore, the length of the vehicle's entry and exit space when parked facing forward is three meters. The space released after the three sections are folded is exactly more than three meters, which does not affect the entry and exit of the vehicle and its occupants.

[0014] Instructions, operating instructions, and other markings can be painted or affixed to the fire-resistant fiber cloth on the outer layer of the composite fire-resistant layer.

[0015] The folding body is preferably made of carbon steel square or round tubes. These tubes have high hardness and strong corrosion resistance, and have a longer service life in extremely harsh outdoor environments. Composite fireproof layer materials include high-temperature resistant and flame-retardant materials such as basalt fiber, high-density ceramic fiber cloth, high-silica fiber, rock wool, modified alumina or silica.

[0016] The canopy poles are connected and fixed to the folding body using curved connecting frames to prevent rainwater accumulation. To enhance protection, a composite fireproof layer is installed on both the inner and outer sides of the isolation frame.

[0017] All materials of the isolation frame are treated with anti-corrosion coating. The vehicles and automobiles mentioned include electric bicycles (two-wheeled, three-wheeled, and small four-wheeled), fuel vehicles, electric vehicles, and new energy vehicles.

[0018] Taking a passenger car with a length of 4.8 meters and a height of 1.7 meters as an example, the space required by the partition is larger than the vehicle's dimensions. The same requirement applies to the dimensions of vehicles such as three-wheeled electric vehicles.

[0019] For two-wheeled electric vehicles, this isolation rack is designed to reduce the number of vehicles required so that multiple vehicles can be stored.

[0020] When used in a relatively fixed location, it can be equipped with fire extinguishing pipe nozzles and other fire-fighting equipment.

[0021] The composite fireproof layer has fireproof fiber cloth and flame-retardant buffer layer as the base fireproof materials, and other functional materials and layers can be added.

[0022] The composite fireproof layer is recommended to be 2 to 3 centimeters thick, which provides sufficient thickness to increase the elastic cushioning effect in the event of an accidental vehicle impact.

[0023] Because the main body of the left and right folding structure is wide, in order to solve the problem of applying force when pulling forward, the strength of the first column at the front should be strengthened or a new column should be added; for the canopy frame that is not high and can be reached by hand, a reinforcing rod connecting the two sides of the folding structure should be set at the top to assist the pushing and pulling activities.

[0024] In areas of the composite fireproof layer that are prone to friction and vehicle contact, wear-resistant fiber materials are applied.

[0025] For parking areas with many vehicles, fire protection facilities are generally not designed for individual vehicles, so the isolation frame itself does not necessarily need to be equipped with fire protection equipment and its interface.

[0026] The independently equipped fire-fighting equipment is not effective.

[0027] The reduced overall length of the folding rack facilitates logistics, transportation, and storage.

[0028] The casters are equipped with a braking and locking mechanism that allows for manual operation and prevents free movement.

[0029] This isolation frame is suitable for underground parking lots, carports, garages, ground-level venues, and outdoor parking lots where multiple vehicles are parked.

[0030] When the isolation frame is in use, it is anchored to the ground by iron chains or ropes to prevent abnormal movement due to windy weather.

[0031] The isolation rack should be used with caution or stored away during windy weather.

[0032] The bottom edge of the isolation frame and the corresponding composite fireproof layer are both attached to the ground to effectively block the spread of combustibles.

[0033] The isolation frame effectively prevents the fire from spreading to the surrounding areas, providing better protection for nearby vehicles and buildings.

[0034] The purpose of installing casters on the isolation frame is to make it easier to push the protective frame from multiple directions to open up a larger working space when there are vehicles parked on one or both sides of the vehicle, which is conducive to vehicle entry and exit and personnel getting on and off the vehicle.

[0035] The beneficial effects of this invention are: A foldable fireproof vehicle isolation rack is used to create an isolated protective space for parking vehicles, providing a routine protection. It can also be moved to prevent fires from spreading outwards from vehicles in the event of a fire, better protecting nearby electric bicycles, fuel vehicles, electric vehicles, new energy vehicles, and buildings, reducing property damage and environmental pollution, and giving rescuers more time.

[0043] The following will be combined with the appendix Figures 1-6 The present invention will be further illustrated through the examples.

[0044] exist Figures 1 to 3 The folding vehicle fireproof isolation frame mainly consists of a roof pole, a folding body, guide rail convex plates, and casters. The roof pole structure includes three types: traditional grid combination frame, flat roof pole, and curved roof pole. The flat and curved roof poles are independent connecting rods, serving to connect the left and right folding bodies into a unified structure. Due to the grid-connected movable combination structure between the folding bodies, the overall structural strength is not an issue. The directional moving wheels connected to the folding body move back and forth within the guide rail convex tube. One end of the guide rail convex tube with a caster wheel acts as a limit during sliding nesting. When one side of the guide rail convex tube extends out of the nested combination, the front and rear guide rail convex tubes have corresponding limiting grooves to prevent detachment. It is worth noting that the directional moving wheels located at the front and rear ends of the guide rail convex tube are positioned inside the guide rail convex tube, preventing the directional moving wheels from folding while the guide rail convex tube does not move synchronously. The convex shape of the guide rail convex tube provides movement space and limiting settings, and its three specifications are designed for compatible combination. The bottom of the guide rail convex tube is equipped with casters, which makes it easier to move the partition frame when parking the vehicle and when people enter and exit the vehicle, so as to expand more activity space, depending on the needs of the left and right sides and the use of the vehicle itself.

[0045] exist Figures 4 to 6In this design, the canopy rod and the folding body are connected and fixed using a curved connecting frame. This frame has multiple fixing holes, allowing for adjustment and modification of the width and height of the combined canopy rod and folding body to accommodate more vehicle models and reduce production volume. The bottom of the guide rail convex tube is equipped with casters, ideally one at the front, one in the middle, and two at the rear. The casters on both sides of the partition are identical. The casters on the guide rail convex tube facilitate easier movement of the partition when parking and occupants enter or exit the vehicle, expanding the usable space. The curved design of the canopy rod connecting to the folding body prevents rainwater accumulation. The composite fireproof layer is used by binding and securing the entire partition with straps, which can also enhance the coverage of the front and rear sides of the passageway, or simply cover the folding bodies on both sides. To enhance protection, composite fireproof layers are added to both the inner and outer surfaces of the partition. This barrier is suitable for vehicles including electric bicycles (two-wheeled, three-wheeled, and small four-wheeled), fuel vehicles, electric vehicles, and new energy vehicles. Depending on intelligent management needs, additional detection and warning devices for temperature, smoke, and wind speed can be added. The protective space of this barrier can accommodate the size of the vehicle. The barrier conforms to the width of the parking space plan and provides some additional space for movement.

[0046] In this embodiment, the purpose of setting up a three-section nested combination structure is that, for a vehicle that is close to five meters long, the door frame positions on both sides of the driver's side are basically at the center of the vehicle's length. In addition, there is an extra half meter of space to accommodate getting out of the vehicle. Therefore, the length of the vehicle's entry and exit space when parked facing forward is three meters. The space released after the three-section structure is folded is exactly more than three meters, which does not affect the entry and exit of the vehicle and its occupants.

[0047] In this embodiment, the caster wheel is equipped with a braking and locking mechanism to prevent free movement.

[0048] In the technical description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a movable combination connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can readily understand the specific meaning of the above terms in the technical expression of this invention.

[0049] As described above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the technical requirements and scope of the embodiments. Therefore, if these modifications and variations of the embodiments fall within the scope of the claims of the present invention and their equivalents, the intent of the present invention also includes these modifications and variations.
