Importance and improvement measures of buffer handle for railway passenger car door
I. Introduction
In our daily life, taking the train has become a common way to travel. However, in the process of getting in and out of the car, the opening and closing of the door often brings a lot of troubles, especially for the high-speed train. The impact of the door switch is great, which will not only cause inconvenience to passengers, but also cause safety accidents. Therefore, in order to solve this problem, a device named "buffer handle of railway passenger car door" is designed.
Second, what is the bumper handle of the railway passenger car door?
As the name implies, "bumper handle of railway passenger car door" is a safety device installed on the train door. It reduces the impact force when closing the door by setting a handle with a specific structure, and effectively prevents the automatic opening phenomenon caused by too fast speed. In addition, this handle can also improve the safety and convenience of passengers getting on and off.
Third, the working principle and technical characteristics
1. Working principle: The device mainly relies on the built-in spring, damper and other components to effectively control the moving speed of the door. When the passenger pulls or pushes the door, the spring will compress first to store energy; In the release process, the damping effect is used to gradually convert this part of potential energy into heat energy and radiate it, so as to slow down the closing action. This can not only avoid the noise pollution caused by strong collision sound, but also protect passengers from the risk of accidental injury.
2. Technical features:
(1) Lightweight design: made of high-strength aluminum alloy, which not only ensures sufficient strength but also reduces the overall weight;
(2) Good wear resistance: the surface has good corrosion resistance and scratch resistance after special treatment, which can keep beautiful for a long time and prolong the service life;
(3) Simple and flexible operation: the handle is ergonomic in shape, comfortable to hold and not easy to slip off, and even the elderly or children can easily complete the door opening/closing operation;
Iv. application status and development prospect
At present, many new EMUs have begun to widely adopt such advanced technologies and products to improve the user experience. With the improvement of China's high-speed rail network and the increasing demand of passengers, the requirements for related supporting facilities will become more and more strict in the future. It is foreseeable that "bumper handle for railway passenger car door" will become one of the important projects that major manufacturers are competing to develop for a long time to come.
V. Conclusion
In a word, the appearance of "bumper handle for railway passenger car door" greatly improved people's experience when riding the train, and also promoted the pace of technological progress in the whole rail transit industry. We look forward to more similar outstanding innovation achievements constantly emerging to jointly promote China's modernization drive to a higher level!
