A total of 9 annual awards were awarded in the competition.、28 awards for technological innovation、There are 10 user selection awards and 4 feature awards.。Among，Shandong Changlong Automobile Manufacturing Co., Ltd.（Hereinafter referred to as Changlong Trailer）Trailer Gantry Technology Wins Scene Innovation Award（5 items in total）。

Scientific and Technological Innovation Iteration Leads Industry Development

The first China Commercial Vehicle Black Technology Competition in 2022 was hosted by China Automotive Engineering Research Institute Co., Ltd.，China Automotive Engineering Research Institute Co., Ltd. Beijing Institute、Jointly sponsored by Commercial Vehicle Network，Roland Berger Management Consulting, a leading international think tank、Oliver Wyman Management Consulting as a think tank support，Truck Treasure Technology、Hefei Weitian Express（Road Song）And so on，The competition was awarded by the US-China Automobile Exchange Association.、Strong support from Gaishi Automobile Network and other units and industry experts and leaders。

The expert evaluation committee of the competition is composed of 17 Chinese and foreign experts.，Fu Yuwu, Honorary President of China Automobile Engineering Society, served as the chairman of the evaluation committee.。The competition was also highly concerned by He Guangyuan, Minister of the former Ministry of Machinery Industry, and gave guidance.。

The First China Commercial Vehicle Black Technology Competition Reflects Openness in the Selection、International and innovative，It has been officially launched in Beijing since October 2022.，The competition has been received from the whole vehicle enterprises in the commercial vehicle field.、There are more than 100 projects for spare parts enterprises and science and technology enterprises.。

These enterprises include domestic enterprises.、Joint ventures and cooperative enterprises and foreign-funded enterprises in China，Covering traditional fuel technologies、New Energy Technology、Ecological construction of commercial vehicles，Covering the whole vehicle、Parts、Software and other fields，And relate to improvement of a manufacturing process of a commercial vehicle.、Combined or single performance boost、Control system and scenario solutions, etc.，Showing high innovation、Focus on the pain points and difficulties of the industry，Some projects have been applied in practice and achieved good expected results.，There are still some projects that have not yet landed.，However, it has high potential for transformation and development.，It fully demonstrates the frontier direction and development trend of high-end technology in the field of commercial vehicles.。

This contest presents two major characteristics.，First, the electric technology of commercial vehicles occupies a considerable proportion.，Two, many parts and technology companies have submitted good projects.，The cross-border integration of commercial vehicle parts enterprises and technology enterprises has brought more possibilities to China's commercial vehicle industry.。

 

Changlong Trailer Black Technology Products

The award-winning technology of Changlong trailer is the trailer gantry.。 

Trailer anti-collision has been the focus of research in the field of semi-trailer safety.，In particular, goods such as steel coils are easy to impact forward due to inertia during emergency braking.，The goods hit the gantry，Even break through the cab，Causing a car crash and death.。

Technical difficulties faced by the industry，A new type of trailer anti-collision structure is designed for Changlong trailer.。The novel anti-collision structure comprise a beam and an upright post,，The crossbeam is installed at the bottom of the trailer.，Throughout the trailer，One end of the beam close to the cab is provided with an upright post.，Notch at the joint between the bottom of the column and the cross beam，One end of the beam is inserted into the interior of the upright post，Weld and fix。

In order to further enhance trailer crash safety，The beam is adoptedHSection steel，Columns are made of high elastic steel，The bending resistance of the beam and the column is greatly improved,，To further reduce self-weight，The cross beam is provided with a lightening hole.。

Compared with the traditional technology of the industry，This new structure can effectively strengthen the impact resistance of the front end of the trailer.，After the column is impacted by the cargo，Toughness absorbs some of the impact.，Prevent the cargo from directly impacting the cab，So as to avoid the occurrence of malignant traffic.。

Technology is cool，The future is beautiful。Changlong trailer will create greater value driven by black technology.，Turn Product Power into Market Power，Promote industrial upgrading，Leading China's Commercial Vehicle Industry to a Better Tomorrow。
