From May 8 to June 7, the Ministry of Industry and Information Technology publicly solicited opinions on the mandatory national standard revision project of the "Technical Requirements for Safety of Automobile Door Handles", and planned to make provisions on the layout, signs, safety functions, structural strength of electric and hidden door handles, which aroused social concern.

With the rapid development of electrification and intelligence of automobiles, hidden door handles such as "leverage" and "electrocontrolled pop-up" are widely used. Its advantage is that it integrates with the car body, which can reduce the wind resistance coefficient, thereby reducing fuel consumption of fuel vehicles, increasing the battery life of electric vehicles, and improving the overall appearance and technology sense, which has been favored by many users.

At the same time, during the market application process, related problems and safety hazards are also exposed - for example, hidden without signs, many people report that it is difficult to find or get used to it; some collisions and fire accidents are likely to cause power outage of vehicles, causing the electric door outside handle and the door inside handle, increasing the difficulty of rescue and escape obstacles; there is no obvious unified sign, which increases the difficulty of operation in emergencies...

The reporter learned that at present, for car door handles, there are no relevant standards abroad, and the existing domestic relevant standards only put forward technical requirements for the durability, strength, high and low temperature resistance, vibration resistance of door handles.

The mandatory national standard revision plan project of the "Technical Requirements for Safety of Automobile Door Handle" which was publicly solicited for opinions, stipulates the installation requirements of the internal handle of automobile emergency doors, the logo requirements of the internal handle of hidden doors and emergency doors, the anti-clip requirements and test methods of the external handle of electric doors, the strength requirements and test methods of the external handle of doors and doors, and the dynamic test requirements and test methods of electric door handles.

A relevant person in charge of the Science and Technology Department of the Ministry of Industry and Information Technology said that from the perspective of rescue and escape, the safety logic of the car door outside handles in accidents such as collisions and vehicle fires should be strengthened, and safety redundant design requirements such as mechanical or power outage protection should be added to ensure that the door system can be opened in accidents such as power outages and collisions, so as to carry out rescue and escape activities.

The person in charge said that it is also necessary to ensure that in rolling and falling accidents, the door handles can be prevented from being incorrectly affected, thereby reducing the risk of occupants falling; standardize safety signs that are easy to identify in hidden door handles and emergency door handles to ensure the visibility of the signs, thereby reducing the difficulty of occupants' escape in emergencies; ensure the structural strength of the door handles and prevent the loss of the function of the rear door lock control mechanism from occurring in accidents.

The standard of automobile door handles is not only a technical and design issue, but also a safety issue. Concealed door handles are standardized to prevent safety issues from being "invisible".

The issue of hidden door handles has attracted industry attention. Heads of many car companies such as Xiaopeng Motors and Great Wall Motors said on different occasions that there are insufficient design problems for hidden door handles. Xiaopeng Motors said it is developing door handles that can be opened better in extreme situations.

In recent years, my country's new energy vehicle industry has developed rapidly. With the accelerated application of many new technologies, it is more important to strengthen their safety risk assessment and accelerate the improvement of relevant standards while improving the experience.

The new national standard for electric vehicle batteries is released, requiring upgrades to not catch fire or explode; automobile companies are required to fully carry out combined driving assistance test and verification, and shall not exaggerate or false propaganda; it is planned to issue standards and technical requirements for safety of automobile door handles... For some time, a series of policy measures in the automotive field have sent a positive signal that my country has stepped up its efforts to promote high-quality development of the industry.

"Promoting the formulation of national standards for safety technology of automobile door handles is not only a timely correction of the problems exposed in the development of the new energy vehicle industry, but also a escort for the vigorous development of my country's advantageous industries." Industry experts pointed out that giving innovation necessary growth space, while better coordinating development and safety, and fastening a "sat belt" for scientific and technological development requires all parties to continue to work together.
