What affects the comfort of a car?
In many people's hearts, the standard of good car, comfort may be the most important, after all, to buy a car is to enjoy, not to suffer. Driving is to bring convenience and pleasure to work and life. Especially after the car enters the family, its role is increasingly valued by consumers, and there is nothing wrong with the pursuit of comfort. Combined with their own needs to consider comprehensively. So where do you look at comfort? What factors affect the comfort of a car? 1, the interior space To determine whether the vehicle is comfortable, the first thing to look at is the seating space in the vehicle. Of course, the "interior space" is only used for the comparison between the same class of vehicles, and if there is a cross-level comparison, it loses its meaning. (Although there are currently some A+ class vehicles on the market, the internal space has exceeded the "compact" Class B vehicle phenomenon in the individual interior spaces.) The ride space in the vehicle should be from the three aspects of the lateral (length), vertical (width) and height Look. For the front row space, since the main and auxiliary seats can be adjusted before and after, it is mainly to see that the head space and width are not enough. For the rear seating space, in addition to looking at the head space and width, the legroom is not enough. It should also be noted that at present, many manufacturers like to rely on the mobility of their family cars, the rear window from the B-pillar to the C-pillar will shrink more and more, and the window opening area will become smaller and smaller. This will make passengers sitting in the back row feel depressed and prone to motion sickness. 2, seat comfort The large interior space does not necessarily mean that it is comfortable, and the comfort of the seat is equally important. Although the internal space of some models is large, if the design of the seat does not conform to the body, it will still make people feel uncomfortable. So when we experience seat comfort, we mainly look at three points: The first point is the thickness and softness of the seat. The second point is the length of the seat. Some manufacturers use the “stealing space†design to shorten the length of the rear seats in order to give consumers the false impression that the rear leg space is rich. Can not fully support the thighs of the rear passengers, long-distance ride will feel uncomfortable. The third point is the wraparound of the seat. When the car is turning, the body of the person in the car will also be shaken. At this time, the well-wrapped seat will give people a strong sense of support and will put your body in. Fixed in the seat, the amplitude of shaking is greatly reduced. 3, chassis suspension When the vehicle is open and dynamic, chassis suspension has a direct impact on comfort, in addition to seat comfort. Many people think that the softer suspension car is more comfortable to sit up. In actual fact, the soft suspension generally has long strokes, and it tends to produce more vibrations on the road, and the body swings more horizontally. In this kind of situation, the car sat up and feels like a boat, but it will feel very comfortable in a short time, but it will feel uncomfortable for a long time and it will make people feel motion sick. Therefore, for a family car, moderately soft and hard suspension is most suitable, although there will be some tremors in some uneven sections such as gullies and canyons, but the suspension filter is more direct and does not produce extra shaking, giving a very good impression. Resilience feeling. 4, tire comfort Tires are also one of the factors that determine the comfort of vehicles. Nowadays, tires on the market can be divided into many types according to their functionality. There are focus on grip, focus on quiet, and explosion-proof tires. The explosion-proof tires used in some high-end luxury cars are more secure in terms of safety, but they are harder than ordinary tires, have a strong sense of quake when they pass through some potholes, and have more fragmentation and vibration and are uncomfortable. If you pay attention to comfort the best choice for quiet tires, often driving friends know that no matter how good a car's noise engineering works, fetal noise will inevitably directly into the compartment, so choose a set of tires is equivalent to The noise at the source was reduced, which was more direct than the cost of strengthening the soundproofing effect of the car in the last few thousand yuan. 5, gearbox The gearbox of the car also has a lot to do with comfort. In general, the CVT gearbox is the best in terms of comfort and ride comfort. The AT gearbox takes care of the smoothness and mobility. The dual clutch gearbox pays more attention to sports. The frustration at low speeds has been a common problem that cannot be solved perfectly, so the smoothness is not as good as the first two. Therefore, if you want to drive comfortably, choose a dual-clutch gearbox carefully. You can choose a CVT gearbox or an AT gearbox.
Meniscus lens is a lens which has two spherical curved surfaces, convex on one side and concave on the other side. It is thicker at the center than at the edges. The lens provides a smaller beam diameter in order to reduce the beam waste and spherical aberration.
Positive meniscus lens is a convex-concave lens thicker at the center than at the edges. It is used to minimize spherical aberration. When used in combination with another lens, it will shorten the focal length, and increase the NA of system.
Negative meniscus lens is a convex-concave lens thinner at the center than edges. It increases the divergence of the beam without introducing any significant spherical aberration. When used in combination with another lens, it will increase the focal length and decrease the NA of the system.
