Front bumper leather introduce

The car bumper is a safety device that absorbs and reduces external impact forces, protects the front and rear parts of the vehicle body. Many years ago, the car front and rear bumpers were made of steel plates stamped into channel steel, riveted or welded together with the longitudinal beams of the frame, and had a large gap with the vehicle body, which looked very unattractive. With the development of the automotive industry and the widespread application of engineering plastics in the automotive industry, As an important safety device, car bumpers have also embarked on a path of innovation. Today's car front and rear bumpers not only maintain their original protective functions, but also strive for harmony and unity with the body shape, and pursue their own lightweight. The front and rear bumpers of cars are made of plastic, which people call plastic bumpers The plastic bumper of a typical car is composed of three parts: the outer panel, cushioning material, and crossbeam. The outer panel and cushioning material are made of plastic, and the crossbeam is stamped with cold-rolled thin sheets to form a U-shaped groove; The outer panel and buffer material are attached to the crossbeam. The plastic bumper is composed of three parts: the outer panel, buffer material, and crossbeam. The outer panel and buffer material are made of plastic, and the crossbeam is stamped with a cold-rolled thin plate with a thickness of about 1.5 millimeters to form a U-shaped groove; The outer panel and cushioning material are attached to the crossbeam, which is connected to the longitudinal beam of the frame by screws and can be removed at any time. This plastic bumper uses two types of materials, polyester and polypropylene, and is formed by injection molding. June 26, 2013, The National Automobile Products Industry Federation, the Vehicle Accessories Technical Committee of the National Automobile Standardization Technical Committee, and Guangdong Dongjian Group jointly released the Chinese "Automotive Protective Bars" industry standard. This standard was drafted by Guangdong Dongjian Group, with multiple domestic research institutions and professional institutions participating in the discussion and approval by the Ministry of Industry and Information Technology. It is reported that the Chinese "Automotive Protective Bars" industry standard has been officially announced, This marks a breakthrough in the industry standard for automotive protective bars, filling the gap in domestic standards. The standard will be officially implemented nationwide on September 1, 2013, attracting great attention from industry manufacturers and sellers. Firstly, using corner indicator columns to determine the position of the bumper. The vertical mark on the corner of the bumper is an indicator column, and some company products also have the type of automatic extension and retraction driven by the motor. This type of corner indicator column, It is possible to correctly confirm the position of the bumper corners, prevent damage to the bumper, improve driving skills, and for those who are prone to scratching the bumper, it is best to install a trial. With this corner marker post, the position of the bumper can be accurately determined in the driver's seat, which is very convenient. Secondly, installing corner rubber can reduce damage to the bumper. The edges of the bumper are the most vulnerable part of the car shell, and people with poor driving experience are more likely to scratch the edges, It's covered in scars. The corner rubber can protect this area, just stick it to the corner of the bumper, and installation is very simple. This method can reduce the degree of damage to the bumper. Of course, if the rubber is damaged, it can be replaced with a new one. In addition, the corner rubber is a thick rubber pad, which is attached to the corner of the bumper. If you want to look overall with the car, you can spray paint on it)

Explanation of the front face of a car

The front face of a car is called the grille, also known as the front face, ghost face, grille, and water tank cover. Its main function is to provide air intake and ventilation for the water tank, engine, air conditioning, etc., preventing foreign objects from damaging the internal components of the car during driving and showcasing individuality. In automotive engineering, the grille is used to cover the body of the car to allow air to enter. Most vehicles have a front grille to protect the radiator and engine, The other common grille is located under the front bumper. The advantage of the front face of a car is that the front face, as the visual center of the car, is also a top priority in car design. The beauty and ugliness of the front face directly affect people's perception of the car's form. Different car brands also have their own family style facial makeup to achieve visual unity in appearance. The front face design of a car includes the engine hood, front headlights, The grille of the water tank and the front edge of the engine, like the eyes, mouth, and chin of a human face, form unique facial features. By utilizing the winding lines and details of the body, the design contours are created

BMW 6 Series introduce

The BMW 6 Series is a car specially designed by BMW Germany for sophisticated drivers. It was introduced in 1976 and discontinued in 1989. During this period, its sales reached 86000 units, making it the most successful box car in BMW's history After a 14 year hiatus, BMW decided to revive the 6 Series and once again enter this large luxury sports car market, showcasing the core concept of the BMW 6 Series in GT racing, combining the advantages of sports cars and luxury RVs The previous models of BMW's sporty two door cars have also perfectly achieved this integration. In terms of exterior design, the 6 Series maintains the typical dynamic style of BMW Coupe, with a long hood, low roof lines, and front and side skirts giving the car a dynamic and elegant posture. To distinguish it from other models, the headlights, engine cover, radiator grille, and front air vents have all been redesigned. By introducing new elements such as LED brake lights in the tail light design, in addition to greatly reducing reaction time, the size and brightness can be adjusted according to different environments. The BMW v8 engine provides power for the 6 Series. BMW is known for its advanced technological development, and a series of LED brake lights have been introduced. The application of high-tech projects has maintained BMW's leading position in the automotive industry. The 6 Series has also adopted many advanced scientific research achievements. The new 6 Series has a body length of 4820mm and a width of 1800mm, which is even wider than the 5 Series. Such a large body shape will inevitably increase the weight of the body, and excessive body weight will greatly affect the acceleration and handling of the 6 Series. Therefore, BMW has used a large amount of aluminum alloy and composite materials on the body of the 6 Series, In order to achieve the goal of reducing weight, carbon fiber reinforced plastic materials are 50% lighter than steel and 35% lighter than aluminum, which can effectively reduce the weight of the vehicle body. The rigidity is three times that of other materials in the central control area (10 sheets), and the collision resistance and safety are quite good, which has always been an ideal material for the automotive industry. However, due to the lack of stamping equipment, carbon fiber used to be produced manually. BMW has developed a set of stamping equipment with a self weight of 200 tons and a pressure of 1800 tons, which is the world's first mass-produced carbon fiber roof, and has begun trial use on the new 6 series. The 6 series also uses an overhead display (hud) system that is only available on aircraft, which can directly display some important information. Projected onto the windshield of the car, including navigation direction, speed, and active cruise control display. The core functions related to driving in the car are operated through the i-drive controller and buttons attached to the steering wheel, but the i-drive control button is placed on the right side of the gear lever and requires arm extension to reach. Other secondary functions and comfort equipment control are arranged in a distance that is easily accessible to the other (2) cars and front seat passengers, Very convenient. Users can also choose a panoramic glass roof that is much larger than a regular electric sunroof, allowing more sunlight to enter the luxurious interior of the car. Dynamic driving and active steering systems are optional equipment for the 6 Series, which can greatly eliminate the body roll caused by vehicle turning and increase the comfort of passengers inside the car. The active steering system, on the other hand, changes the steering ratio based on the vehicle speed through a stepper motor. At lower speeds, the steering sensitivity increases, and larger wheel turns can be achieved by turning the steering wheel at a smaller angle. This situation is very useful for drivers driving on urban roads or parking and turning around. As the speed increases, the steering becomes more sensitive. Accurate, ensuring driving stability and comfort. The BMW 6 Series engine is equipped with Dynamic Stability Control (DSC) and Dynamic Traction Control (DTC) systems. In addition, the Driving Dynamics Control (DDC) technology used in the BMW M3 and M5 models is also used in the new 6 Series, which is controlled through a "SPORT" button located on the center console The DDC function can increase the sensitivity of the throttle response, improve acceleration ability, and provide a more direct response to the power assisted steering mechanism, thereby increasing the driving pleasure of the driver. In terms of power, there is also the option to choose a sequential manual transmission (SMG), which can be changed by the paddles on the steering wheel or the gear lever. As for the interior, we have always trusted BMW. The 6 Series adheres to BMW's consistent style, perfectly combining luxury and practicality. The bright colors are more in line with its sporty characteristics, and there are multiple configurations to choose from. As a representative of luxury cars, the BMW 6 Series [2] also has many commendable features. In terms of sound configuration, the new BMW 6 Series is equipped with 8 features. A hi fi sound system with speakers, 9 space seats, and 6 CDs create a home theater effect
