Talking about the safety of the car, in addition to the body structure, safety configuration, etc., a good vision is also an important part. Then, is the view of a car excellent, and how to evaluate it?
I believe that many drivers have rich experience: the exterior mirrors, interior mirrors, and the width and slope of the A-pillars directly determine whether the blind spot of driving can be overcome.
End: the era of rearview mirrors
Some models that do a good job in terms of vision, such as Subaru Senri and Honda Fit, work together to maximize the driver's field of vision by pairing the ABC column with a slimmer and larger rearview mirror. In addition, the addition of some new technologies can also help drivers better grasp the surrounding situation, such as the Mercedes-Benz E-class 360° camera.
Right now, as the "ultimate killer" to improve the blind spot of sight - the camera is replacing the rearview mirror step by step. In Japan, the proposal to cancel the rearview mirror was officially passed, and the rearview mirror of the car will gradually withdraw from the historical stage.
The traditional car rearview mirror is considered to be the driver's second pair of eyes, and its existence has been close to 100 years of history. The rearview mirror, which was officially born in 1921, has undergone many technological innovations. Many of the new rearview mirrors we see today are no longer a simple lens.
For example, the double curvature mirror technology can eliminate blind spots when turning, and the field of view is doubled. The anti-glare technology can reduce the influence of the rear vehicle glare on the driver's line of sight when driving at night.
However, even if automakers add a lot of new technology to the rearview mirror and continue to improve the blind spot, the shortcomings of the rearview mirror cannot be ignored. For example, it sometimes obscures part of the side line of sight; when the car is in a narrow section, when it is reloaded into the warehouse, or even into the automatic car wash area, the rear view mirror is likely to be damaged. More importantly, the rearview mirror has a negative impact on the drag coefficient. The higher the drag coefficient, the higher the actual fuel consumption.
Rotary Switches
The Rotary Switches, different with Key Switches, Metal Switches, Toggle Switches and Automotive Switches, is mainly installed on liquid and gas pipelines to regulate the flow and pressure of liquids and gases. When used, turn the handle to drive the adjusting nut to rotate, and connect the left-hand thread of the valve through the left-hand thread. Drive the valve to move right or left to change the cross-sectional area of the right hole passage in the valve body cavity, so as to adjust the liquid and gas in the upper outlet pipe.
The Electrical Rotary Switch is a switch that controls the opening and closing of the main contact by rotating the handle.There are two types of rotary switches, namely a unipolar unit structure and a multi-pole multi-position structure. Unipolar unit rotary switches are often used in conjunction with rotary potentiometers in applications, while multi-pole multi-position rotary switches are often used for switching of operating line.
Multi Position Rotary Switch, because of its use, the overall use of sealed structure, there is a certain degree of waterproof effect, the basic can reach the IP67 waterproof level.At the same time need to use a more rigid and durable metal material, there are two or three files in the gear difference.
