Frameless car doors are very stylish. What are their shortcomings?

Now that the domestic auto market has entered the equipment competition stage, no one is willing to lose to their opponents in terms of configuration. Therefore, domestic consumers can be said to have everything they ask for in terms of configuration.

As for the few rare configurations, frameless doors should be one of them.

Of course, not all models are suitable for frameless doors. Generally speaking, frameless doors are standard equipment for sports cars, and some coupe-style cars are also equipped with them.

The models in the domestic auto market that use frameless door designs are relatively expensive, and they are all very good-looking models, such as Volkswagen CC, BMW MINI, Mercedes-Benz Smart, etc., all of which have frameless doors. Adopted by these personalized models.

The reason is that the double improvement in temperament and appearance brought by frameless doors is immediate. For now, models equipped with frameless doors are not cheap, so they are naturally built-in. Aristocratic.

In addition to good looks, the aristocratic look of frameless doors is also due to their relatively high cost.

Compared with the most common framed doors, frameless doors need to take into account more technical issues, the most basic ones such as sound insulation and waterproofing.

In addition, due to the more complex mechanical structure, the failure rate is slightly higher. Therefore, in order to overcome these problems, frameless doors do require more cost investment.

It is precisely because of these advantages that frameless doors do have many disadvantages. For example, it may be impossible to open the door in winter. When the window is closed, the upper edge of the window It may be stuck to the rubber parts of the car body due to extreme cold weather.

Since most of these models have limited space, the usage rate of the other seats is not too high. In extremely cold weather, the four-door windows may be stuck tightly.

If things continue like this, the life of a ring of sealing tape will be greatly reduced, and eventually problems such as abnormal noise in the windows, abnormal driving noise, and even water leakage may occur in severe cases.

Furthermore, sealing problems may lead to a decrease in noise isolation performance in the car.

Technically speaking, for many frameless door models, when opening the door, the glass will automatically drop by 0.5 cm, and after closing the door, it will automatically rise to block the sealing strip. Theoretically, the sealing effect will not be affected, but in practice Compared with the framed doors, it is still lacking.

Moreover, because the implementation of this technology requires a more complex mechanical structure, the window lifter is more likely to fail.

Lastly, it is purely a human reason. Many car owners have reported that every time the passengers get off the car, they will feel a little nervous. For no other reason than that many passengers do not know that it is a frameless car door. In this case, just push the glass with your hands and close the door vigorously.

Although it will not cause the glass to break, it will leave fingerprints, etc., and the glass will begin to loosen over time, thereby aggravating the severity of problems such as abnormal noise and water leakage.

Although this is a small thing, it is really annoying. No wonder some car owners said that the frameless doors do look very cool, but whoever uses them knows the taste.

In fact, the above-mentioned problems are very common in related car model forums. It can also be seen from the complaint website that complaints about abnormal noise in the door, water leakage in the body and even cracked glass are common. The stability is obviously not as good as that of traditional framed doors.

Moreover, due to the high positioning of these models, the maintenance costs are also very considerable.
