With the upgrading of the consumer market, sales of luxury commercial vehicles equipped with electric doors have increased rapidly; with the development of intelligence, intelligent electric door systems have also become a future development trend. Electric sliding doors and lift doors are the most mature technologies and cost-effective. Smart access mode. In order to meet the increasing demand for vehicles from domestic customers and lead the development direction of domestic luxury commercial vehicle technology, in order to achieve rapid iterative research and development of the electric and intelligent door system, the PanAsia Automobile Door System team relies on pre-research projects, innovation workshops, seed funds, quality tools, virtual evaluation and other methods to carry out rapid iterative research and development of smart electric doors on an annual basis. The innovative development of smart electric doors fully draws on the Internet development model: rapid iteration, not based on model development for 3-5 years, but on an annual basis; cross-border innovation, drawing on technologies from other industries and integrating resources; Customer experience defines product technology development centered on customer usage scenarios. Due to the complex movement mode of electric sliding doors and lifting doors, the operating force during the opening and closing process, the operating sound, and the abnormal noise generated during driving are more easily perceived by customers. At the same time, combined with other needs of internal and external customers, the door system perceives quality, Space convenience, cost, weight and intelligent electronic control are the main evaluation indicators of competitiveness. Perceived quality: Improve operating sound through continuous iterative innovation of sliding door rollers, guide rails, and PSD drives; optimize the positioning stability of sliding doors through the development of positioning buckles and buffer systems to eliminate abnormal noises on bad roads; develop variable rigidity buffer blocks and variable CLD sealing strip systems through door closing force analysis software to optimize door closing force; improve side matching through iterative optimization of hinge and body subsystems. Convenient space: Reduce the lateral space occupied by the sliding door system through the new generation of middle brackets, door locks, glass surfaces, lower brackets, etc., and improve the interior space. Cost and weight: Through optimization of design structure and application of new materials, the iterative development of throttle interlock, sealing system, aluminum alloy door, and latch front lock has been completed. At the same time, a new generation of electric actuators and anti-pinch systems have been developed, which has improved product performance while significantly reducing cost and weight. Intelligent electronic control: Develop new electronic control components to replace traditional mechanical components. The functions of electronic control components are realized through intelligent electronic control, giving customers different application scenarios. For example, the transition from traditional key unlocking to carrying ID unlocking will evolve to ID-free entry modes in the near future, such as fingerprint, Face Recognition, etc. Through rapid iterative research and development, the car door system has completed iterative research and development of 37 technical solutions since 2012. Among them, 20 technologies have been applied to the new generation GL8 launched in 2016, achieving improvements in 13 performance indicators in four dimensions: door system perception quality, space convenience, cost and weight, and intelligent electronic control. It has also achieved weight reduction and cost reduction. Compared with the previous generation of bicycles, it has saved 590RMB and reduced weight by 2 Kg. As of December 2018, SAIC GM has saved approximately 90 million yuan in material costs. Through unremitting rapid iteration, we have also obtained fruitful intellectual property results: 4 invention patents; 11 utility model patents; 12 papers published; and 5 relevant science and technology awards. Through this project, Pan Asia Automobile has mastered the core technology for the rapid iterative development of electric and intelligent door systems. It is also the only technology center in the world that has experience in the development of sliding door systems. A complete knowledge system for the development of independent sliding door systems has been established and fully owns independent intellectual property rights. The new generation of GL8 electric sliding doors and lifting doors have a number of domestically initiated and internationally leading advanced technologies, ensuring that the GL8 door system becomes the vane of the development of luxury commercial door systems in China, leading the development direction of domestic luxury commercial vehicles, and at the same time promoting the technological development capabilities of the domestic parts and components industry.
