[0049] In the public transportation sector, buses and tour buses serve as essential modes of public transport, carrying a large number of passengers. To ensure passenger safety, vehicle design incorporates various safety measures, including emergency door opening systems, a crucial mechanism that allows passengers to quickly evacuate the vehicle in emergencies. Traditional emergency door opening systems are designed based on the premise of normal vehicle operation, namely, under conditions of a stable power supply and sufficient air supply, using electronic control signals to activate pneumatic actuators to drive the opening and closing of the doors.

[0050] However, reality is often more complex than anticipated. In extreme environments, such as when a vehicle is involved in a serious traffic accident, a natural disaster, or when its electronic systems are damaged, the vehicle's electrical and pneumatic systems may fail simultaneously. In such cases, traditional emergency opening systems that rely on electricity and air pressure become ineffective, and the doors cannot be opened by conventional means, blocking escape exits. Passengers and drivers then need to find alternative methods to open the doors, but often due to a lack of the necessary tools or knowledge, the process is complex, time-consuming, and in severe cases, impossible to open manually, directly threatening the lives of those involved.

[0051] Currently, most buses on the market primarily rely on manual unlocking mechanisms for electrical faults, with relatively few solutions for situations involving both electrical and pneumatic system failures. While these technologies enhance vehicle safety to some extent, their effectiveness under extreme conditions still needs improvement.

[0052] Combination Figure 1 As shown in the specific embodiment of this application, an emergency door opening system for a vehicle is provided, comprising: a vehicle air source assembly 10, the vehicle air source assembly 10 having an air source exhaust port; a backup air source assembly 20, the backup air source assembly 20 having a first backup air source port and a second backup air source port, the air source exhaust port being connected to the first backup air source port; a door opening button 50, the door opening button 50 having a first button pneumatic port and a second button pneumatic port, the first button pneumatic port being connected to the second backup air source port; and a door control assembly, the door control assembly having an execution port, the execution port being connected to the second button pneumatic port and the air source exhaust port respectively; wherein, the door opening button 50 has a first working position connecting the backup air source assembly 20 to the air path of the door control assembly, and a second working position disconnecting the backup air source assembly 20 from the air path of the door control assembly.

[0053] By applying the technical solution of this utility model, through the pneumatic connection between the backup air source component 20 and the door control component, and the dual working position switching function of the door opening button 50, in the extreme case of failure of the vehicle's main air source, the backup air source component 20 and the door control component can be quickly connected by simply operating the door opening button 50. The high-pressure air from the backup air source component 20 can be used to automatically open the door, improving the vehicle's emergency response capability in the absence of power and air, ensuring that passengers and drivers can escape quickly and safely in an emergency, greatly shortening the escape preparation time caused by technical obstacles, reducing operational complexity, effectively protecting life safety, and solving the problem in the prior art of how to achieve rapid emergency opening of the door by simple operation when the vehicle's electrical circuit and air circuit fail simultaneously.

[0054] Furthermore, the emergency door opening system also includes: a first suppression valve 40, which is installed on the connecting pipe between the backup air source assembly 20 and the door opening button 50; and a first control module, which controls the first suppression valve 40 to operate according to vehicle speed data, so as to connect the backup air source assembly 20 and the door opening button 50.

[0055] In this embodiment, the first suppression valve 40 is installed in the pipeline between the backup air source assembly 20 and the door opening button 50, forming a safety barrier. During normal vehicle operation, the first control module precisely controls the first suppression valve 40 to remain closed based on real-time vehicle speed data, effectively preventing accidental door opening due to misoperation of the door opening button 50 and avoiding driving safety risks. However, in emergency situations, especially when the vehicle speed is below a set threshold, the first suppression valve 40 automatically opens, ensuring unobstructed airflow between the backup air source assembly 20 and the door opening button 50. This allows the operator to immediately activate the backup air source, enabling rapid and automatic door opening, greatly improving the speed and efficiency of emergency response and providing strong protection for passenger safety evacuation.

[0056] In one exemplary embodiment, such as Figure 2 As shown, the vehicle air supply assembly 10 includes: a vehicle air supply 101, which has an air supply exhaust port; and a main vent valve 102, which is disposed on the connecting pipeline between the vehicle air supply 101 and the backup air supply assembly 20; wherein the vehicle air supply 101 can be selectively connected to or disconnected from the backup air supply assembly 20 through the main vent valve 102.

[0057] By applying this embodiment, the system can maintain the independence and efficient utilization of the main air source during normal operation through the main vent valve 102 between the vehicle air source 101 and the backup air source assembly 20.

[0058] Furthermore, the backup gas source assembly 20 includes: a gas storage tank 202, which has a first backup gas source port and a second backup gas source port, the first backup gas source port being connected to the port of the main vent valve 102; and a one-way valve 201, which is disposed on the connecting pipeline between the main vent valve 102 and the gas storage tank 202.

[0059] In this embodiment, the air tank 202 serves as a critical backup air source. Its first backup air source port is tightly connected to the main vent valve 102, ensuring a rapid replacement supply of high-pressure air in the event of a failure of the main vehicle air source 101. The one-way valve 201 further optimizes air source management. Located in the pipeline between the main vent valve 102 and the air tank 202, it ensures that high-pressure air can only flow unidirectionally from the vehicle air source 101 to the air tank 202. During normal vehicle operation, this effectively prevents pressure leakage from the air tank 202, maintaining sufficient pressure in emergency situations. This design not only ensures the availability and safety of the backup air source but also provides a rapid and stable air supply in emergencies, enabling one-button emergency door opening. This provides a solid guarantee for the safety of passengers and the driver, significantly improving the overall system performance and emergency efficiency.

[0060] Furthermore, such as Figure 3 As shown, the door opening button 50 is located on the driver's side window and is connected to the vehicle interior components. The placement of the door opening button 50 on the driver's side window and its close integration with the vehicle interior components greatly facilitates the driver's rapid response in emergencies. The driver can operate the door opening button 50 within easy reach without leaving the driver's seat, enabling one-button emergency door opening and saving valuable time for emergency evacuation. Furthermore, the connection to the interior components ensures the button's stability and ease of operation, guaranteeing accuracy even when the vehicle is bumpy or tilted, further enhancing the practicality and reliability of the emergency system.

[0061] In this embodiment, as Figure 4 , Figure 5 and Figure 6 As shown, the air tank 202 is located inside the vehicle frame and is connected to the vehicle frame. The air tank 202 is spaced apart from the door control assembly, the vehicle air supply assembly 10, and the door opening button 50. The precise positioning of the air tank 202 inside the vehicle frame not only makes full use of the space inside the vehicle structure, but also ensures the stability and safety of the air tank through its effective connection with the vehicle frame.

[0062] In one exemplary embodiment, the door control assembly includes at least a front door control assembly 60 and a middle door control assembly 70, with air source exhaust ports connected to corresponding execution ports of the front door control assembly 60 and the middle door control assembly 70, and a first button pneumatic port connected to at least one corresponding execution port of the front door control assembly 60 and the middle door control assembly 70.

[0063] In this embodiment, the independent configuration of the front door control assembly 60 and the middle door control assembly 70 significantly enhances the flexibility and responsiveness of the emergency door opening system. The exhaust port of the vehicle air supply assembly 10 is directly connected to the execution ports of these two control assemblies, ensuring a direct supply of air from the main air source and maintaining normal door operation. Simultaneously, the first pneumatic port of the door opening button 50 is connected to the execution port of at least one door control assembly. This design ensures that even in an emergency where the main air source fails, operating the door opening button 50 can directly command the front door or middle door control assembly to activate the backup air source, enabling rapid door opening.

[0064] Furthermore, the emergency door opening system also includes: a first emergency control component 80, which has a first emergency port and a second emergency port. The first emergency port is connected to an exhaust port, and the second emergency port is connected to a corresponding execution port of one of the front door control component 60 and the middle door control component 70; and a second emergency control component 90, which has a third emergency port and a fourth emergency port. The third emergency port is connected to an exhaust port, and the fourth emergency port is connected to another corresponding execution port of the front door control component 60 and the middle door control component 70.

[0065] In this embodiment, the first emergency control component 80 and the second emergency control component 90 each have independent emergency ports, which are respectively connected to the exhaust port of the vehicle's air supply and the execution port of the door control component. Under extreme conditions where both the main power supply and the air supply fail, passengers or rescue personnel can manually operate the first or second emergency port of the first emergency control component 80 and the third or fourth emergency port of the second emergency control component 90 to directly act on the control components of the front or middle doors, forcing the doors to open and creating an escape route for emergency evacuation.

[0066] In one exemplary embodiment, the first emergency port of the first emergency control component 80 and the third emergency port of the second emergency control component 90 are respectively connected to the outlet of the main vent valve 102. The main vent valve 102 controls the connection and disconnection between the vehicle air source 101 and the first and second emergency control components 80 and 90. The outlet of the main vent valve 102 is precisely connected to the first emergency port of the first emergency control component 80 and the third emergency port of the second emergency control component 90, realizing centralized management and flexible control of the air circuit between the vehicle air source 101 and the emergency control components. The main vent valve 102 can quickly control the supply or cut off of the air source according to the needs of an emergency, ensuring that the first and second emergency control components 80 and 90 can respond immediately in various emergencies, realizing the rapid opening of the vehicle door without relying on the normal operating state of the vehicle.

[0067] In one exemplary embodiment, at least one of the first emergency control component 80 and the second emergency control component 90 includes: an external emergency valve 903, the first port of which is connected to the exhaust port of the air source; a second suppression valve 901, the first port of which is connected to the second port of the external emergency valve 903, the second port of which is connected to the exhaust port of the air source, and the third port of which is connected to the execution port; and a second control module, which controls the second suppression valve 901 to operate according to vehicle speed data to connect the vehicle air source component 10 and the door control component.

[0068] In this embodiment, the connection between the external emergency valve 903 and the air source exhaust port ensures that external rescue forces can quickly intervene, and the emergency cutoff or supply of air source can be achieved through valve body operation. The second suppression valve 901, as the key to air path switching, forms a multi-layered pneumatic control path through its series connection with the external emergency valve 903 and the air source exhaust port, and its parallel connection with the execution port. Even in complex emergency situations, it ensures that at least one door can be opened. The vehicle speed data monitoring function of the second control module gives the system the ability to automatically adjust the emergency valve's opening and closing status according to vehicle dynamics, effectively avoiding the risk of misoperation during driving, while ensuring the immediate availability of the emergency door opening function when the vehicle is at low speed or stationary.

[0069] In one exemplary embodiment, at least one of the first emergency control component 80 and the second emergency control component 90 includes: an in-vehicle emergency valve 902, the first port of which is connected to the air source exhaust port; a second suppression valve 901, the first port of which is connected to the second port of the in-vehicle emergency valve 902, the second port of which is connected to the air source exhaust port, and the third port of which is connected to the execution port; and a second control module, which controls the second suppression valve 901 to operate according to vehicle speed data to connect the vehicle air source component 10 and the door control component.

[0070] In this embodiment, the first port of the in-vehicle emergency valve 902 is directly connected to the air source exhaust port, enabling passengers to immediately trigger the air source cutoff or release in an emergency, creating conditions for the door to open. The second suppression valve 901, acting as the air circuit management hub, has its first port connected to the second port of the in-vehicle emergency valve 902, which is also connected to the air source exhaust port. Its third port is associated with the execution port, forming a direct pneumatic link from internal operation to door control. The second control module guides the opening and closing of the second suppression valve 901 based on real-time vehicle speed data, ensuring that the in-vehicle emergency valve 902 remains locked during high-speed vehicle operation to prevent accidents. At low speeds or when the vehicle is stationary, the emergency valve unlocks, enabling one-button or manual emergency door opening, providing passengers with a timely and effective escape route. This also reduces safety risks caused by improper operation, demonstrating the system's human-centered and efficient design.

[0071] In one exemplary embodiment, at least one of the first emergency control component 80 and the second emergency control component 90 includes: an external emergency valve 903, the first port of which is connected to the exhaust port of the air source; an internal emergency valve 902, the first port of which is connected to the second port of the external emergency valve 903; a second suppression valve 901, the first port of which is connected to the second port of the internal emergency valve 902, the second port of which is connected to the exhaust port of the air source, and the third port of which is connected to the execution port; and a second control module, which controls the second suppression valve 901 to operate according to vehicle speed data to connect the vehicle air source component 10 and the door control component.

[0072] In this embodiment, the direct connection between the external emergency valve 903 and the gas source exhaust port ensures rapid control of the gas source status during external rescue. The internal emergency valve 902 further facilitates this, with its first port immediately following the second port of the external emergency valve 903, enabling a smooth connection between internal and external emergency operations. The second suppression valve 901, as the core control element, connects at one end to the second port of the internal emergency valve 902 and at the other end to the gas source exhaust port. Crucially, its third port is connected to the execution port, establishing a direct channel from emergency triggering to door control. The second control module precisely regulates the opening and closing of the second suppression valve 901 based on vehicle speed information, achieving safe locking of the internal emergency valve 902 during high-speed vehicle operation to prevent accidental operation. Simultaneously, it ensures the constant availability of the emergency door opening function at low speeds or when stationary, significantly enhancing the passenger's survival chances in crisis situations.

[0073] In one exemplary embodiment, at least one of the front door control assembly 60 and the middle door control assembly 70 includes a door pump solenoid valve 601 and a door pump cylinder structure 602. The door pump solenoid valve 601 is connected to the outlet of the main vent valve 102, and the door pump solenoid valve 601 is also connected to the door pump cylinder structure 602. The integration of the door pump solenoid valve 601 and the door pump cylinder structure 602 in either the front door control assembly 60 or the middle door control assembly 70, along with their connection to the outlet of the main vent valve 102, significantly enhances the immediacy and accuracy of emergency door opening. As the central control unit for pneumatic operation, the door pump solenoid valve 601 can quickly respond to commands from the main vent valve 102, instantly adjusting the airflow to the door pump cylinder structure 602 to ensure the door can be quickly unlocked and opened in an emergency. This direct air and electrical connection eliminates redundant intermediate steps, enabling a direct and efficient transition from air source release to door operation. This greatly shortens emergency response time, improves passenger safety evacuation efficiency during crises, and fully demonstrates the ingenuity and practicality of the system design.

[0074] In one exemplary embodiment, at least one of the front door control assembly 60 and the middle door control assembly 70 includes: a door pump solenoid valve 601 and a door pump cylinder structure 602, wherein the door pump solenoid valve 601 is connected to the door opening button 50 and a second suppression valve 901 corresponding to the first emergency control assembly 80 and the second emergency control assembly 90.

[0075] In this embodiment, the door pump solenoid valve 601 is directly connected to the door opening button 50, the first emergency control component 80, and the second suppression valve 901 in the second emergency control component 90, constructing a rapid-response and flexible door control mechanism. As a key actuator, the door pump solenoid valve 601 can instantly respond to the command from the door opening button 50. Simultaneously, it works closely with the control links of the first and second emergency control components 80 and 90 to ensure rapid and accurate control of the door pump cylinder structure 602 in both normal operation and emergency situations. This design not only improves the convenience of opening the door in daily use, but more importantly, in emergency situations, whether through driver operation, passenger emergency triggering, or intervention by external rescue personnel, the instantaneous response of the door pump solenoid valve 601 can quickly unlock and open the door, providing passengers with a rapid escape route and greatly enhancing the overall safety performance and emergency response capability of the vehicle.

[0076] In an exemplary embodiment, the emergency door opening system further includes a rocker switch assembly 30, which includes a first rocker switch 301 and a second rocker switch 302. The first rocker switch 301 is electrically connected to the door pump solenoid valve 601 corresponding to the front door control assembly 60, and the second rocker switch 302 is electrically connected to the door pump solenoid valve 601 corresponding to the middle door control assembly 70. The door pump solenoid valve 601, the first rocker switch 301, the second rocker switch 302, the second control module, and the first control module are respectively electrically connected to the vehicle power supply.

[0077] Using this embodiment, in an emergency situation where the vehicle's power supply and pneumatic systems are operating normally, the driver can simply press either rocker switch forward to directly command the corresponding door pump solenoid valve 601 to activate the door opening air path, causing the door pump cylinder structure to open the door and quickly provide an escape exit. Similarly, after the emergency subsides, by pressing the rocker switch backward, the driver can immediately switch to the door closing procedure, cutting off the door opening air path and connecting the door closing air path to ensure the safe closure of the doors and restore traffic order.

[0078] According to another specific embodiment of this application, a vehicle is also provided, including a door emergency opening system, which is the door emergency opening system described above.

[0079] This invention integrates the aforementioned emergency door opening system, which, through innovative design and multiple redundancy mechanisms, ensures rapid and safe evacuation of passengers in various emergency situations. The emergency door opening system comprises an electronically controlled emergency door opening system, a pneumatic emergency door opening system, and a one-button emergency door opening system. Each subsystem is equipped with unique components, such as a rocker switch, solenoid valve, main vent valve, check valve, air tank, and one-button opening button. These components work together to form a highly reliable safety network. Whether under conditions of sufficient power and normal air pressure, or in extreme situations such as loss of power and air pressure, the emergency door opening system can ensure the doors open quickly through different activation methods, such as driver operation, passenger manual operation, or intervention by external rescue personnel, providing an escape route for passengers. This comprehensive emergency preparedness and response capability significantly enhances the overall safety performance of the vehicle, especially in the public transportation sector, providing strong protection for passenger safety.
