Description

Air-conditioned car simple escape window

technical field

The utility model belongs to a new simple escape window device for an air-conditioned car, specifically a device that can be installed on an air-conditioned car. When an emergency occurs, the emergency switch is activated to automatically turn the large glass window to solve the problem of escape in a closed car. It is a simple escape window for air-conditioned vehicles for emergency escape of passengers when encountering danger.

Background technique

In recent years, with the expansion of city scale and the increase of urban population mobility, buses have become the most widely used public transport in major cities. In order to meet people's travel needs, the number of buses has been greatly increased, and air-conditioned buses are favored by people because of their luxury and comfort. There are more and more domestic cities, and some cities have even lost sight of ordinary buses. The shadow of the car.

The safety of bus passengers is increasingly concerned. During peak hours, almost every bus is overloaded, with at least 8 people per square meter of space, and many of them are old, weak, sick and disabled. With such a dense crowd, the possibility of effectively escaping when an emergency and vicious accident occurs is relatively low. Once there is a danger such as a fire, the harm to passengers is very serious. This kind of danger generally has no warning, and once it occurs, it will inevitably cause chaos on the scene, thereby amplifying the harm itself. The current bus escape methods are as follows:

(1) The emergency switch of the car door; the emergency switch of the car door is set above the top of the car door. When an emergency occurs, turn the knob to balance the cylinder pressure in the cylinder driving the door open with the outside world, so as to reduce the pressure caused by the cylinder when the door is opened manually. resistance. Existing problems: Through our actual investigation, we found that the emergency switch is set at a high position. Some models are hidden inside and can only be used after opening the cover. Ordinary passengers do not know how to use the emergency switch. When an emergency occurs, it will cause operational difficulties. Even if the operation is completed, the passenger needs to move the door by hand to open the door. Assume that when the number of passengers is large, the car is crowded with people, and the door is full of passengers, there is no room for turning to open the door, and the closed door cannot be opened, so self-rescue cannot be effectively carried out.

(2) Escape hammer: In an emergency, use the escape hammer to smash the window glass and jump out of the window to escape, but the use of the escape hammer also requires skills and methods. Once a burning emergency occurs in the car, it is very inconvenient to smash the window glass , Many passengers do not know the location of the escape hammer. The survey found that a large number of ordinary bus escape hammers are often "handled" by passengers, and it is not uncommon for them to be lost.

(3) Sunroof escape If an emergency occurs in the car, you can also turn on the emergency switch of the roof sunroof, then push open the sunroof, grab the hand rail, step on the seats on both sides to support it, and get out of the roof to escape. However, the safety window on the roof is relatively high. In an emergency, generally a tall male passenger can push it open. Since the exit of the safety window is small, it needs to be supported by force. This method is not suitable for the elderly, women, and children. escape. These escape devices generally require the calm handling and orderly evacuation of passengers to cooperate. But in fact, when passengers see a car full of people, raging fire, and small escape exits, their first instinct is: it is more difficult to escape by themselves, and panic and uncomfortable behaviors are inevitable. And panic is contagious and resonant among the crowd at this time, causing overall chaos. This is the consequence of serious disadvantages brought about by the depression and disappointment of the current status of the bus escape system.

In recent years, incidents of smoke and fire on buses have occurred frequently in various places. On June 5, 2009, a bus burning accident in Chengdu (27 people were killed, 74 people were injured, and only 7 people escaped) fully demonstrated that the urgency of public transportation safety The seriousness of sex and escape hidden danger needs to be solved urgently. In order to solve the escape problem in the sudden disaster of air-conditioned vehicles, we urgently need to install a window opening device that can provide an escape channel in an emergency and cannot be easily opened without reason. The device is simple to operate, does not affect the sealing, and utilizes the existing starting device on the bus, which is easy to realize and low in cost.
