It is a professional technology company integrating the research and development, production and sales of automobile inspection equipment. The company has strong new product research and development and production capabilities. The products involve three major categories of products in the field of automobile research and development and production, and the company's products are sold at home and abroad. There are more than 120 domestic automobile manufacturers alone, including domestic Geely, FAW, BAIC, Suzhou Golden Dragon, Xiamen Golden Dragon, Hebei Zhongxing, Zotye Hanteng, Kaiwo Automobile (formerly Nanjing Golden Dragon), BAIC Foton, Xinjiao, Diancha Automobile, Hezhong Automobile and other well-known automobile manufacturers.
The software program, mechanical design, and electrical control parts all have independent intellectual property rights. So far, more than 20 patents have been obtained, including overall hardware design patents for the testing line, software works, and mechanical platform modification patents. In particular, the integrated automobile emission and comprehensive safety performance inspection platform includes 9 patents (Patent 1, 2020211041843; Patent 2, 2020211045454; Invention Patent 3, 2021101465311; Patent 4, 2021202919016; Patent 5, 2021202918954; Invention Patent 6, 2021101468856); Patent 72020225964079; Patent 82020225992295; Patent 92020226110901
The main functions of the comprehensive safety performance test bench are as follows:
1. It meets all the test items of braking performance in GB7258: including braking force, braking distance of road test, braking deceleration, braking stability, braking coordination time and other test items, completely replacing road test. 2. It fully meets the national standard GB\/T36987-2018 "Automobile Anti-lock Braking System (ABS) Performance Test Method"; our company can test the core indicator of ABS, the slip rate; 3. The national standard commercial vehicle electric control system (EBS) performance requirements and test methods have been completed on October 19, 2019, and the draft has been completed and will be released soon. The introduction of the national standard shows the importance of EBS to vehicle safety. EBS is an upgrade of ABS. Before ABS starts working, BS will automatically detect the difference in friction resistance between each wheel and the ground and make timely redistribution of the braking force to adapt to the road surface. Since ABS is an active safety system that actively participates in the braking process, EBD, EBS, and ABS are all instantaneous closed-loop working mechanisms. Only our company's pure mechanical inertia test bench, which includes 6 patents, can achieve instantaneous response and completely equivalent road test, so it can realize the performance test of ABS and EBS (EBD). The imported comprehensive drum benches are mechanical plus motor electric inertia composite inertia simulation test benches. Due to the delayed response time of the motor's back electromotive force during emergency braking, and the absence of a flywheel group and a third roller structure, the test bench can be used for testing the performance of ABS and EBS (EBD). The structure is simple, so the shortcomings of the structural principle determine that the imported integrated drum table cannot achieve rapid equivalent road tests. Therefore, in addition to testing the braking force, it does not have the above three national standard testing functions. The imported integrated drum table lags behind the needs of all vehicle safety performance tests. The imported integrated drum table can only be used as a brake table and can only test the braking force according to GB7258. Although the imported integrated drum can be used for dynamic road tests to test acceleration or shifting performance, the acceleration performance or shifting performance is more suitable for testing on the 72-inch or 48-inch chassis dynamometer developed by the automobile. The actual use survey conclusions of the car factory have confirmed the above statement. The off-line inspection of automobiles is mainly to meet the national standard on comprehensive safety Performance requirements or alternative road tests, to test the overall safety performance of the car. Acceleration and shifting performance is not a safety test item required by the national standard, so the off-line inspection also does not test the acceleration and shifting performance due to the tactile limit. Our comprehensive safety performance test bench fully meets the three national standard inspection requirements! Imported comprehensive drum benches have fallen behind the national standard requirements of China! Our comprehensive safety performance test bench has far exceeded the imported comprehensive drum benches. This product is suitable for production plant trial production lines, vehicle off-line, modified vehicle vehicle inspection, passenger station gate inspection line, social annual inspection line, especially dangerous goods vehicles (comprehensive safety inspection) and commercial vehicle electronic control system EBS performance inspection, providing timely and effective solutions.
One patent for ADAS calibration and one patent for exhaust emission system.
Some of our automotive testing equipment has obtained the EU safety and quality system certification and has been exported to the Philippines, Uruguay, Mongolia, Kazakhstan, Iran, Myanmar, Nigeria, and other countries.
High-end testing equipment for automobile factories: contact dynamic 4-wheel alignment, non-contact dynamic laser 4-wheel alignment, integrated drum table, comprehensive automobile safety performance test platform (including ABS and EBS performance test), gantry headlight tester, have been put on the market, and the Intellectual Property Office has accepted 4 invention patents; the key equipment for vehicle R&D experiment "48-inch AC power chassis dynamometer" has been put on the market, indicating that the research and development and industrialization of key testing technologies for smart cars have been formed. Our company is the only domestic enterprise that fills the gap in high-end testing line equipment "non-contact dynamic laser 4-wheel alignment, integrated drum table, gantry headlight tester"! AC power chassis dynamometer is the top 3 domestic brand in sales.
Stay true to our original aspiration and take the revitalization of the high-end testing industry as our mission. The success of the above projects will not only break the foreign technical barriers and monopoly, but will also greatly enhance our country's comprehensive strength and influence in this field! It's a relief for the Chinese people!!!
