Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of traffic safety, and particularly relates to a passenger car rapid escape device. BACKGROUND

[0002] When a passenger car is on fire due to spontaneous combustion, arson or collision, passengers face great challenges in escaping. The existing passenger car escape device usually relies on a small number of doors, small-sized windows or skylights, but the windows are relatively high from the ground, resulting in low escape efficiency, especially for the disabled, the elderly and children. For example, some solutions use skylights for escape, but the disabled have difficulty in climbing; some solutions focus on escape methods, but ignore the control of smoke and high temperature. Smoke and high temperature often accumulate in the upper space of the passenger car, and passengers are easy to lose the ability to escape due to inhaling toxic smoke.

[0003] In the prior art, there are preliminary designs involving bottom escape slides or fireproof isolation, such as CN207141205U, which controls the escape slide and fire blanket through a mechanical bolt rod and a manual drum. The existing device relies on manual operation of the bolt rod and the drum, which may fail due to operation errors or delays in fire panic; the fire blanket is only deployed through a simple chute, lacks an intelligent triggering mechanism, and cannot respond to the fire source in real time; the triggering point of the escape slide is single, which is controlled only through a connecting rod, and if the key node is damaged, the whole function will be paralyzed. Therefore, the present application provides a passenger car rapid escape device. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a passenger car rapid escape device to solve the above problems.

[0005] To achieve the above purpose, the present application is implemented by the following technical scheme: a passenger car rapid escape device, comprising a vehicle body, an escape slide arranged at the bottom of a passenger cabin of the vehicle body, and a fire blanket arranged above an engine compartment, further comprising a central control unit, a temperature sensor and a smoke sensor, the central control unit being electrically connected with the temperature sensor and the smoke sensor, and being used for monitoring the environment of the engine compartment and the passenger cabin in real time; a locking mechanism of the escape slide is driven by an electric push rod, and the electric push rod is controlled by the central control unit, when one of the temperature sensor and the smoke sensor detects an abnormality, the central control unit automatically triggers the electric push rod to push the escape slide to unfold; the fire blanket is matched with a chute through an electric drum, and the electric drum is also driven by the central control unit, so as to realize automatic deployment of the fire blanket, and form an integrated linkage system.

[0006] Preferably, the central control unit is installed in the passenger cabin instrument panel, the temperature sensor is arranged near the engine compartment, and the smoke sensor is distributed on the top of the passenger cabin of the vehicle body; when a fire is detected, the central control unit first starts the electric roller to release the fire blanket to isolate the fire source, and then triggers the electric push rod to deploy the escape slide after a delay of 0.5 seconds to ensure orderly escape.

[0007] Preferably, the locking mechanism includes a locking pin, the bottom of the passenger compartment of the vehicle body corresponds to the opening of the escape slide, and the bottom of the opening is a luggage compartment. One end of the escape slide is hinged to one side of the opening at the bottom of the vehicle body, and the other end of the escape slide is fixedly connected to the other side of the opening at the bottom of the vehicle body by the locking pin. A pull sleeve is movably sleeved on one side of the head of the locking pin, and an electric push rod is installed on one side of the bottom of the vehicle body corresponding to the locking pin position, and the movable push rod of the electric push rod is fixedly connected to the pull sleeve.

[0008] Preferably, the deployment mechanism of the escape slide further includes a multi-point control unit, which consists of multiple metal wires and multiple manual emergency handles. A manual pull ring is fixedly connected to the outer side of the locking pin head. One end of each metal wire is connected to the manual pull ring of the escape slide, and the other end extends to multiple locations in the passenger cabin through a guide wheel, including the driver's seat, the side door, and the rear seats. The manual emergency handle is located at the end of the metal wire. By pulling the metal wire using the lever principle, passengers can mechanically release the escape slide by pulling the manual emergency handle from any position, serving as a backup for the automatic system.

[0009] Preferably, the fire blanket is made of composite fire-resistant material, including a ceramic fiber layer and an aluminum foil reflective layer. The fire blanket is rolled up to the bottom of the engine compartment by a roll-up rack, and a groove is fixed to the edge of the engine compartment. Guide sliders are fixedly connected at equal intervals to the edge of the fire blanket, and the guide sliders are slidably connected in the groove. An electric drum is fixedly connected to the front side of the engine compartment corresponding to the end of the groove. The outer end of the fire blanket is fixedly connected to the electric drum by a steel wire rope.

[0010] Preferably, one end of the main body of the electric drum is connected to the output shaft of the drum motor via a coupling, and the other end is fixedly connected to a through convex shaft, the outer end of which extends through the vehicle body and out of the vehicle.

[0011] Preferably, the central control unit integrates a wireless communication module, which is linked with the vehicle GPS and alarm center. When the sensor is triggered, it automatically sends a location alarm to the monitoring platform and activates the cabin audible and visual alarm to alert passengers. The wireless communication module uses a 4G / 5G chip, and the audible and visual alarm emits a high-frequency sound and flashing red light to guide passengers to the escape slide in an orderly manner.

[0012] Preferably, the bottom sides of the luggage compartment are slidably connected to retractable cabins via telescopic guide rails. The retractable cabins are positioned on one side corresponding to the locking mechanism of the escape slide, and locking pedals are provided on the inner sides of the retractable cabins corresponding to the escape slide positions.

[0013] Preferably, the retractable cabin has an emergency exit on its outer side wall, and an escape door is fixed inside the emergency exit with easily broken rivets. After sliding into the luggage compartment, passengers can kick open the escape door to escape to the ground.

[0014] Preferably, it also includes a backup power supply, which is a supercapacitor connected to the central control unit. The backup power supply provides power for at least ten minutes when the main power supply fails, ensuring the continuous operation of the sensor and the central control unit.

[0015] Beneficial effects

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This invention uses a central control unit, temperature sensors, and smoke sensors to monitor the engine compartment and passenger cabin environment of a bus in real time. In the event of an emergency such as a fire, the temperature sensor detects an abnormal rise in ambient temperature, and the smoke sensor detects an abnormal increase in smoke concentration. Once either the temperature sensor or the smoke sensor detects an abnormal signal, the signal is rapidly transmitted to the central control unit. By integrating sensors and actuators in the central control unit and providing unified control of all components, the invention automates the detection of abnormal temperatures and smoke, the deployment of escape slides, and the deployment of fire blankets. This significantly improves the safety of the bus in emergencies and increases the chances of passenger escape, enabling effective responses to dangerous situations such as fires and ensuring passenger safety.

[0023] 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.

[0024] Please see Figures 1-4 A rapid escape device for a passenger vehicle includes a vehicle body 1, an escape slide 2 installed at the bottom of the passenger compartment of the vehicle body 1, and a fire blanket 4 installed above the engine compartment 3. It also includes a central control unit 14, a temperature sensor 15, and a smoke sensor 16. The central control unit 14 is electrically connected to the temperature sensor 15 and the smoke sensor 16 to monitor the environment of the engine compartment 3 and the passenger compartment in real time. The locking mechanism of the escape slide 2 is driven by an electric push rod 17, which is controlled by the central control unit 14. When one of the temperature sensor 15 or the smoke sensor 16 detects an abnormality, the central control unit 14 automatically triggers the electric push rod 17 to push the escape slide 2 out. The fire blanket 4 cooperates with a slide 11 via an electric roller 12, which is also driven by the central control unit 14, to achieve automatic deployment of the fire blanket 4, forming an integrated linkage system.

[0025] The central control unit 14, temperature sensor 15, and smoke sensor 16 monitor the engine compartment 3 and passenger cabin environment of the bus in real time. In the event of an emergency such as a fire, temperature sensor 15 will detect an abnormal increase in ambient temperature, and smoke sensor 16 will detect an abnormal increase in smoke concentration. Once either temperature sensor 15 or smoke sensor 16 detects an abnormal signal, the signal will be quickly transmitted to the central control unit 14.

[0026] Upon receiving an abnormal signal, the central control unit 14 will respond immediately. For the escape slide 2, the central control unit 14 will control the electric push rod 17 to activate. The electric push rod 17 pushes the locking mechanism of the escape slide 2, causing the escape slide 2 to quickly extend outside the vehicle body 1, providing passengers with a rapid escape route, allowing them to quickly evacuate the bus in an emergency.

[0027] As for the fire blanket 4, the central control unit 14 drives the electric roller 12. The electric roller 12 cooperates with the slide rail 11, allowing the fire blanket 4 to automatically unfold and deploy along the slide rail 11. The fire blanket 4 will cover the engine compartment 3, effectively blocking the fire source and heat, preventing the fire from spreading further, and reducing the harm caused by the fire to the bus and passengers.

[0028] By integrating sensors and actuators through the central control unit 14, unified control of various components is achieved, realizing automated operation of abnormal temperature and smoke detection, escape slide deployment, and fire blanket deployment. This greatly improves the safety of the bus in emergency situations and the chances of passenger escape, enabling effective response measures to be taken at the first moment in the event of a fire or other dangerous situation, thus ensuring the safety of passengers' lives.

[0029] Specifically, the central control unit 14 is installed in the passenger cabin instrument panel, the temperature sensor 15 is located near the engine compartment 3, and the smoke sensor 16 is distributed on the top of the passenger cabin of the vehicle body 1. When a fire is detected, the central control unit 14 first activates the electric roller 12 to release the fire blanket 4 to isolate the fire source, and then triggers the electric push rod 17 to deploy the escape slide 2 after a 0.5-second delay, ensuring orderly escape. The release of the fire blanket 4 can isolate the fire source at the first time, reduce the temperature and smoke concentration in the passenger cabin, and create a relatively safe escape environment for passengers. The 0.5-second delay in deploying the escape slide 2 can prevent smoke from rushing into the luggage compartment 5 and the escape area due to the escape slide 2 deploying too early, and prevent the escape area from being shrouded in smoke, thus affecting passenger escape.

[0030] Specifically, the locking mechanism includes a locking pin 6. The bottom of the passenger compartment of the vehicle body 1 corresponds to the opening of the escape slide 2, and the bottom of the opening is the luggage compartment 5. One end of the escape slide 2 is hinged to one side of the bottom opening of the vehicle body 1, and the other end of the escape slide 2 is pinned to the other side of the bottom opening of the vehicle body 1 by the locking pin 6. A pull sleeve 7 is movably sleeved on one side of the head of the locking pin 6. An electric push rod 17 is installed on one side of the bottom of the vehicle body 1 corresponding to the position of the locking pin 6, and the movable push rod of the electric push rod 17 is fixedly connected to the pull sleeve 7. When the central control unit 14 triggers the electric push rod 17, the movable push rod of the electric push rod 17 pushes the pull sleeve 7, and the pull sleeve 7 causes the locking pin 6 to be pulled out from the pinned position, thereby releasing the fixation between the escape slide 2 and the other side of the bottom opening of the vehicle body 1. At this time, the escape slide 2 rotates downward around the hinge point with the bottom opening of the vehicle body 1 under the action of gravity and quickly unfolds outside the vehicle body 1. This locking mechanism is simple and reliable, ensuring that the escape slide 2 is stably fixed to the bottom of the vehicle body 1 during normal operation, while being able to quickly unlock in an emergency. Meanwhile, the electric push rod 17 has a fast response time, enabling the escape slide 2 to unlock and deploy in a short period of time.

[0031] Specifically, the deployment mechanism of the escape slide 2 also includes a multi-point control unit, which consists of multiple metal flexible wires 20 and multiple manual emergency handles 21. A manual pull ring 8 is fixedly connected to the outer side of the locking pin 6. One end of each metal flexible wire 20 is connected to the manual pull ring 8 of the escape slide 2, and the other end extends to multiple locations in the passenger cabin via guide wheels, including the driver's seat, side door, and rear seats. The manual emergency handles 21 are located at the ends of the metal flexible wires 20. By pulling the metal flexible wires 20 using the lever principle, passengers can mechanically release the escape slide 2 by pulling the manual emergency handles 21 from any location, serving as a backup for the automatic system. The multi-point control unit plays an important role when the automatic system malfunctions and cannot trigger the deployment of the escape slide 2 normally. For example, when components of the automatic system, such as the central control unit 14 and the electric push rod 17, fail due to fire damage or circuit failure, passengers can find the manual emergency handles 21 in multiple locations within the passenger cabin. If the driver finds the automatic system unresponsive, they can quickly pull the manual emergency handle 21. Passengers in the side doors and rear seats can also operate the system by pulling the manual emergency handle 21 in an emergency. Pulling the manual emergency handle 21 manually generates sufficient force to pull the metal cord 20, based on the lever principle. The metal cord 20 has a certain degree of flexibility and strength, accurately transmitting the pulling force to the manual pull ring 8 under the guidance of the grooved wheel. When the manual pull ring 8 is pulled, it causes the locking pin 6 to disengage from its pin position, unlocking the escape slide 2 and allowing it to unfold smoothly under gravity, providing an escape route for passengers. This ensures that even if the automatic system malfunctions, passengers can still manually unfold the escape slide 2 in a timely manner, greatly increasing the possibility of escape and improving the reliability and safety of the entire escape device. The operating structure is simple and reliable; passengers do not need professional knowledge or special training, and can unfold the escape slide 2 simply by pulling it.

[0032] Specifically, the fire blanket 4 is made of composite fire-resistant material, including a ceramic fiber layer and an aluminum foil reflective layer. The fire blanket 4 is rolled up to the bottom of the engine compartment 3 by the unwinding rack 10, and a groove 11 is fixed to the edge of the engine compartment 3. Guide sliders 9 are fixedly connected at equal intervals along the edge of the fire blanket 4, and the guide sliders 9 are slidably connected within the groove 11. An electric drum 12 is fixedly connected to the front side of the engine compartment 3 corresponding to the end of the groove 11. The outer end of the fire blanket 4 is fixedly connected to the electric drum 12 by a steel wire rope. This structural design makes the deployment of the fire blanket 4 smoother and more stable. When the central control unit 14 drives the electric drum 12, the electric drum 12 pulls the outer end of the fire blanket 4 through the steel wire rope. Due to the cooperation between the guide sliders 9 and the groove 11, the fire blanket 4 can be smoothly unfolded along the direction of the groove 11. The ceramic fiber layer has good high-temperature resistance and can withstand the burning of high-temperature flames, effectively preventing heat from being transferred to the passenger cabin. The aluminum foil reflective layer can reflect some heat radiation, further enhancing the heat insulation effect of the fire blanket 4. The design of the roll-up rack 10 facilitates the storage of the fire blanket 4, allowing it to be neatly rolled up at the bottom of the engine compartment 3 in non-emergency situations without taking up too much space. Meanwhile, the steel wire rope ensures the connection strength between the electric drum 12 and the fire blanket 4, preventing breakage during pulling and ensuring that the fire blanket 4 effectively covers the engine compartment 3, isolating it from fire sources and heat. Furthermore, the cooperation of the slide groove 11 and the guide slider 9 prevents the fire blanket 4 from shifting or jamming during unfolding.

[0033] Specifically, one end of the main body of the electric drum 12 is connected to the output shaft of the drum motor via a coupling, and the other end is fixedly connected to a through-shaft 13. The outer end of the through-shaft 13 extends through the vehicle body 1 and out of the vehicle. When the central control unit 14 issues a command to start the drum motor, the motor's power is transmitted to the main body of the drum via the coupling, enabling the main body of the drum to rotate stably. The through-shaft 13 extends through the vehicle body 1 and out of the vehicle. When the electric drum 12 malfunctions, escaped personnel or external rescue personnel can manually drive the electric drum 12 to work by rotating the through-shaft 13 with a socket wrench outside the vehicle, thereby realizing the unfolding of the fire blanket 4. As a backup method for the automatic drive of the electric drum 12, this further ensures that the fire blanket 4 can be deployed normally in an emergency.

[0034] Specifically, the central control unit 14 integrates a wireless communication module 26, which links with the vehicle's GPS and alarm center. When a sensor is triggered, it automatically sends a location alarm to the monitoring platform and activates the cabin audible and visual alarm 27 to alert passengers. The wireless communication module 26 uses a 4G / 5G chip. In an emergency, the audible and visual alarm 27 emits a high-frequency sound and flashing red light to guide passengers to the escape slide 2 in an orderly manner, reducing passenger panic and improving escape efficiency. Through wireless communication via the wireless communication module 26, the monitoring platform can promptly obtain the bus's specific location and emergency situation, enabling rapid deployment of rescue forces. The high-frequency sound and flashing red light can attract passengers' attention in noisy and smoky environments, allowing them to quickly recognize the danger and act according to instructions. Simultaneously, the 4G / 5G chip has high-speed and stable communication capabilities, ensuring that location alarms are transmitted to the monitoring platform quickly and accurately, avoiding delays in rescue due to communication problems.

[0035] Specifically, retractable compartments 18 are slidably connected to the bottom sides of the luggage compartment 5 via telescopic guide rails. Each retractable compartment 18 is positioned on one side corresponding to the locking mechanism of the escape slide 2. Locking pedals 22 are located on the inner sides of the retractable compartments 18 corresponding to the escape slide 2. The bottom of the locking pedals 22 is movably inserted into the bottom of the vehicle body 1, and multiple compression springs are evenly distributed on the bottom of the locking pedals 22. Locking hooks 24 are located on both sides of the upper end of the locking pedals 22 corresponding to the retractable compartments 18, and locking collars 23 are fixed to the inner sides of the retractable compartments 18. Under normal driving conditions, the retractable compartments 18 are stably locked to both sides of the luggage compartment 5 through the cooperation of the locking hooks 24 and the locking collars 23. The compression springs provide upward support for the locking pedals 22, ensuring a tight connection between the locking hooks 24 and the locking collars 23.

[0036] When the escape slide 2 deploys, evacuees slide down into the luggage compartment 5, exerting downward pressure on the locking pedal 22. Since the bottom of the locking pedal 22 is movably connected to the bottom of the vehicle body 1 and has a compression spring, it moves downward under pressure. As the locking pedal 22 moves downward, the locking hooks 24 on both sides of its upper end separate from the locking collars 23, releasing the locking state of the retractable compartment 18. At this time, the retractable compartment 18, aided by the telescopic guide rails, is pushed outward, allowing it to quickly extend to both sides of the vehicle body. After extending, the retractable compartment 18 further expands the space of the luggage compartment 5, providing temporary refuge for more evacuees and preventing overcrowding that could hinder escape. Simultaneously, the emergency exits on the outer walls of the retractable compartment 18 provide more escape routes, increasing escape flexibility and success rate. Moreover, the retractable cabin 18 makes the entire escape process more orderly, reduces the chaos and trampling accidents that may occur during the escape, and further protects the lives of passengers.

[0037] Specifically, the retractable cabin 18 has an emergency exit on its outer wall, and an escape door 19 is fixed inside the emergency exit by a breakable rivet. After sliding into the luggage compartment 5, passengers can kick open the escape door 19 to escape to the ground. The design of the breakable rivet ensures a stable connection between the escape door 19 and the emergency exit under normal circumstances, and also allows passengers to break the door with a simple kicking action in an emergency. When passengers slide down the escape slide 2 into the luggage compartment 5 and enter the retractable cabin 18, in the tense escape atmosphere, they only need to kick the escape door 19 with their feet, and the breakable rivet will break due to the large external force, thus opening the escape passage.

[0038] Specifically, it also includes a backup power supply 25, which is a supercapacitor connected to the central control unit 14. In the event of a main power failure, the backup power supply 25 provides at least ten minutes of power to ensure the continuous operation of the sensors and the central control unit 14. The supercapacitor features fast charging and discharging speeds and high power density, enabling it to quickly power the central control unit 14 and sensors in the instant of main power failure. During these precious ten minutes, the temperature sensor 15 and smoke sensor 16 can continue to monitor the bus environment, and the central control unit 14 can also normally receive and process abnormal signals, controlling the electric push rod 17 and electric drum 12 to ensure the normal deployment of the escape slide 2 and the smooth deployment of the fire blanket 4. Even in the extreme case of a main power failure, the backup power supply 25 can buy crucial time for passenger escape, maintaining the normal operation of the entire escape device. At the same time, the presence of the backup power supply 25 also improves the reliability and stability of the entire bus rapid escape device, giving passengers a greater chance of survival in the face of various emergencies.
