The automobile industry has been in the past hundred years, and there are actually only so many kinds of door design, butterfly doors, cutter doors, side sliding doors, opposing doors and classic Mercedes-Benz gull wing doors. In addition to supercars, new energy vehicles are also racking their brains in the design of doors, including the eagle wing door of Model X, the scissor door of Xiaopeng P7, and the wing door of today's protagonist Gaohe HiPhi X.
First of all, it cannot be denied that the unconventional design of the way to open the door, the return rate is super high. For straight men, a winged door like Gaohe HiPhi X, not only the rear door is open in a folio way, but the roof above the rear row can also be opened, there is a sense of mechanical deformation, and the playability is quite high.
Of course, in addition to being cool, the HiPhi X spread door is not only a flower work, but also designed according to the use of the scene. When getting on and off the car, the rear door and the spread wing door are open, and the air suspension is reduced, so that it is extremely convenient to get on the car, especially for the elderly who can not climb up, and it is difficult to bend over, the design of the wing door is quite practical. In addition to practicality, the wingspan door can also provide an escape window in extreme cases, such as the car turned 90 °, the rear row can go out from the roof, turn 180 ° to climb out of the car door, will not be like the Mercedes-Benz gull wing door also need to be loaded on the hinge, the car needs to blow up the door when the car is reversed.
The four doors + two spread door of Gaohe HiPhi X are all electrically opened, and there is no handle outside, which has two problems, what to do if there is no electricity? What should I do if the door is frozen in the north?
First of all, there are two sets of power supplies for the HiPhi X door power supply, the double redundant design basically does not lead to the door being opened without power, and secondly, even if the very unlucky double power supply is hung, the four doors of the High HiPhi X are reserved for emergency cables, and the function of the cable is the most important, a pull door is opened, double power + mechanical pull lock, do not have to worry about the electric door can not be opened. As for the door being frozen? Gaohe designed a mechanism called Presenter, which can have 50 kilograms of ice-breaking capacity, automatically open the top of the door, if the freezing is too much, then there is a handle that can not be opened, on the hot water bar.
Design doors on the roof, from the Mercedes-Benz 300SL gull wing door era has been a problem - waterproof, compared to the ordinary car's waterway design, the two hinged structures on the roof, in the sealing and drainage has always been more difficult, similar like the convertible car is also easy to leak. The spread wing door of Gaohe HiPhi X naturally has to take this problem into account, first of all, in the use scenario, when the rain sensor detects rain, the spread wing door cannot be opened, only the side door is opened, and the full frame double three-dimensional sealing strip and the newly designed water guide can ensure that there is no leakage in the case of extreme rainfall.
The ceiling has two mouths, how to ensure safety?
Regarding the use of the door, whether from the scene or technical point of view, it is cool enough and at the same time it is also very practical and safe and convenient. However, many people will also be curious, in the rear door to open two openings, the overall strength of the body will not be reduced? How to ensure passive safety?
The first is the overall body design, Gaohe has optimized the shape of each load-bearing part of the HiPhi X body for dozens of wheels, optimized the force transmission path in the event of collision, and dispersed the load. At the same time, two locks were used at the junction between the wingspan door and the body, and the two locks ensured that the door and the body became a tight integration, so that the entire cockpit could efficiently carry the force of the collision. In the choice of materials, the 7 series of high-strength aviation aluminum used on the aircraft is selected as the door reinforcement, and the top I-beam, side columns and front columns are all used 1500MPa ultra-high strength thermoformed steel and so on. In this way, the torsional stiffness of the body reaches a very high level.
Passive safety is the body strength, airbags these are the bottom line of car safety, as a new energy model, the most concerned about safety is battery safety and active safety configuration, in the entire electrical system, Gaohe HiPhi X uses five-dimensional safety design: cell and module safety, battery system integration safety, powertrain, vehicle-level battery system structure security, intelligent safety cloud battery management.
For example, cell and module safety, the use of multiple sensing and monitoring: each module has two temperature sensors and eight cell voltage collectors, can monitor the temperature and voltage in the module in real time; when a collision or combustion occurs, the signal will be directly alarmed through the car system. For example, intelligent security cloud battery management, based on big data and 5G network, Gaohe Automobile's H-SOA electronic and electrical architecture can provide a full range of status visualization for the battery through the real-time interconnection of battery terminals and cloud servers, a large amount of data accumulation, maintain abnormal early warning, and dynamically optimize the use environment and improve battery life.
Active safety is always better than passive safety
In the results of the new round of C-NCAP model evaluation announced by the China Automobile Center, Gaohe HiPhi X won the "C-NCAP Five-Star Safety Evaluation". Among them, the active safety sub-item received a full score, with a scoring rate of 100%, excellent performance, and was at the leading level of the same level. In addition to the ICC Intelligent Navigator, ILC interactive lane change can help the hands and feet of the intelligent driver assistance system.
The most distinctive feature on The HiPhi X is the IVC (Integrated Vehicle Control) vehicle dynamic control system. Based on four major systems of software control, rear wheel steering, braking, and air suspension, actively intervene in driving. Compared with ordinary ESP "after-the-fact" remediation, IVC can control modules such as front wheel steering, rear wheel steering, and electronic limited slip differential (eLSD) to further prevent the risk of understeering, oversteering, skidding and other risks in vehicles, and improve safety under driving limits.
As can be seen above, Gaohe HiPhi X not only has a cool wing spread door design, but also PML headlights to make the light factory look ashamed, and in these key designs (perception, calculation, communication, braking, steering and power supply) also adopts a dual redundancy design, reaching a new height in safety.
