Description

Technical Field

[0001] This utility model relates to the field of subway car door technology, and in particular to a small-sized emergency release device for people and objects caught in subway car doors. Background Technology

[0002] The passenger doors of existing urban rail transit vehicles are generally equipped with anti-pinch functions. The anti-pinch triggering mechanism is based on the cross-sectional area of ​​the pinched object: when the cross-sectional area of ​​the pinched object is greater than 20mm×40mm (slightly different for different lines), the door system can trigger the automatic opening function; however, for small objects such as hair, corners of clothing, and small ornaments (cross-sectional area less than 20mm×40mm), the door system cannot detect the pinched state, that is, it cannot trigger the automatic opening.

[0003] The aforementioned prior art has the following drawbacks:

[0004] 1. If a small object is caught, passengers cannot release it through the anti-pinch function of the train door itself. They need to trigger the emergency stop device (which may cause train delays and operational chaos) or wait for the train to arrive at the next station and open the door (which poses a safety hazard of the caught object injuring passengers or clothing being pulled, causing secondary risks).

[0005] 2. The lack of a dedicated detection and release mechanism for small-sized clamped objects results in insufficient safety of interaction between the vehicle door and passengers / items, and fails to meet the emergency handling needs of small components. Utility Model Content

[0006] The purpose of this invention is to provide a small-sized emergency release device for people and objects caught in subway doors, thereby solving the problems mentioned in the background art.

[0029] Example

[0030] This embodiment provides a small-sized emergency release device for people and objects caught in subway car doors, such as... Figure 1As shown, the vehicle includes a passenger compartment door assembly, a passenger interaction assembly, and a driver's console control assembly. The passenger compartment door assembly includes a first door leaf 1 and a second door leaf 2. The first door leaf 1 has a C-shaped bracket mounting groove 9 welded to its opening edge, and an inflatable sealing ring 3 is embedded within the mounting groove 9. The second door leaf 2 has a sealing strip 4 on its opening edge. The driver's console control assembly includes an air pump 13, a solenoid valve 12, an inflation button 14, and a deflation button 15. The air pump 13 is connected to the inflatable sealing ring 3 via the solenoid valve 12, and the inflation button 14 and deflation button 15 are connected to the solenoid valve 12. The passenger interaction assembly includes a trigger button 8 with a red indicator light, which is electrically connected to the driver's console control assembly. The air pump 13 has an output pressure of 0.6-0.8 MPa, and the solenoid valve 12 is a two-position three-way valve with a response time of less than 0.5 seconds.

[0031] Specifically, the emergency release device in this embodiment involves modifying existing subway passenger car doors. For the existing doors, the original sealing strip of one door is removed, and a bracket mounting groove 9 is installed. A suitable inflatable sealing ring 3 is embedded inside the bracket mounting groove 9, thus creating the first door leaf 1. The original sealing strip of the other door remains unchanged, becoming the second door leaf 2. The inflatable sealing ring 3 of the first door leaf 1 contacts the sealing strip 4 of the second door leaf 2 to seal the subway door. An air pipe 11 is connected to the end of the inflatable sealing ring 3, and the air pipe 11 is connected to an air pump 13. A solenoid valve 12 is also installed on the air pipe 11. The modified driver's console includes a control component with an inflation button 14 and a deflation button 15. The driver can directly press the buttons to control the inflation or deflation of the inflatable sealing ring 3. A trigger button 8 with a red indicator light is installed inside the subway passenger car, which passengers can press to notify the driver of the situation inside the subway passenger car.

[0032] Preferably, the bracket mounting groove 9 is made of stainless steel, the groove depth of the bracket mounting groove 9 is 15mm, and the width of the inflatable sealing ring 3 is 15mm, so that the inflatable sealing ring 3 can fit inside the bracket mounting groove 9. The height of the inflatable sealing ring 3 when deflated is 11mm and the height when inflated is 17mm, so that after deflation, the height difference can release small-sized items that are clamped.

[0033] Preferably, the upper part of the first door leaf 1 has a through hole with a diameter of 10mm. The inflatable sealing ring 3 is connected to the air pipe 11. The air pipe 11 passes through the through hole and is connected to the air pump 13. The diameter of the air pipe 11 is 8mm. The upper part of the first door leaf 1 and the second door leaf 2 is provided with a tank chain 5. The air pipe 11 is installed along the line of the tank chain 5, so that the air pipe 11 will not be squeezed when the door is closed, thus ensuring the stability of the air pipe 11 connection.

[0034] Preferably, a pressure regulating valve 10 is provided on the air pipe 11 connecting the inflatable sealing ring 3 and the solenoid valve 12 to regulate the air pressure entering the inflatable sealing ring 3, adapt to the inflation pressure requirements of the inflatable sealing ring 3, and ensure the stability of the inflation and deflation process.

[0035] Preferably, the passenger interaction component further includes a first wireless intercom 6 and a camera 7. The wireless intercom and camera 7 are installed inside the housing on a profile bracket inside the passenger compartment, within a 1.5m range of the door, allowing passengers to quickly press the trigger button 8 in case of accidental trapping. The first wireless intercom 6 is equipped with a microphone and a speaker with a power of 20W and a communication range of up to 3km. The camera 7 has specific parameters of 4 megapixels, PoE power supply, a focal length of 2.7-8mm, and optical zoom. The driver's console control component also includes a display and a second wireless intercom 16, with the camera 7 electrically connected to the display. The first wireless intercom 6 and the second wireless intercom 16 can communicate with each other. Passengers can communicate with the driver via the wireless intercom device, ensuring that passengers can quickly explain the situation. The wireless intercom also avoids communication difficulties caused by poor signal in the subway. The driver can also observe the passenger situation captured by the camera 7 on the display, thereby ensuring the accuracy of the information transmitted by the passengers. The installation of the wireless walkie-talkie and camera 7 are existing technologies and will not be described in detail here.

[0036] Preferably, the inflation button 14 is equipped with a green indicator light, and the deflation button 15 is equipped with a red indicator light. Using different colored indicator lights helps the driver quickly select the correct operation, avoiding confusion and incorrect presses, thereby improving efficiency.

[0037] Work process:

[0038] When small objects such as hair or clothing are caught in the doors and the original anti-pinch function is not triggered, passengers can press the trigger button 8 to call the driver via the intercom. After the driver confirms the status through the camera 7, he presses the deflation button 15 on the control panel while the subway is still moving. The solenoid valve 12 activates to deflate the inflatable sealing ring 3, reducing its height from 17mm to 11mm. This increases the door gap to release the object. After the passenger removes the object, the driver presses the inflation button 14, and the solenoid valve 12 controls the sealing ring to inflate and reset, raising its height back to 17mm. This allows it to adhere to the sealing strip 4 of the second door panel 2, restoring the door seal. The doors remain closed throughout the journey.

[0039] It should be noted that the emergency release device in this embodiment is an improvement on the existing subway car door. The basic structure and conventional functions of components such as the first door leaf, the second door leaf, the tank chain, and the sealing strip are existing technologies. Therefore, the basic structure of the existing technology will not be described in detail here.

[0040] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
