I remember when I was a child, when I was watching a movie or walking on the street, I would always be attracted by some cool car doors, the most real of which was the frameless car door, when the window was lowered, only half of the door remained, a bit like magic, at that time I could not help but sigh: this is too handsome. Bezel-less doors are only handsome
With the passage of time, frameless doors are not only available to Volkswagen CC, Audi A7L and other high-level joint venture models, but have become the main theme of the domestic automobile market, and have become one of the selling points of various car companies to launch new products, among which Tesla is currently the brand that all its models are equipped with frameless doors as standard. 
Domestic automobile companies such as Changan Qiyuan, Deep Blue Automobile, BYD, Weilai, Xiaopeng Motors, and Leapmotor have also equipped frameless doors on new products to enhance the appearance of new cars and attract the attention of consumers. I don't know if you have found it, in the era of traditional fuel vehicles, it is generally the most expensive and higher-level models that will be equipped with frameless doors, and after entering the new energy era in recent years, it seems that frameless doors have become the standard configuration of new energy flagship models, and less than 200,000 can win products with frameless doors. 
Not to mention, since the car brand has matched frameless doors on its own products, the appearance and temperament have risen all of a sudden, and at the same time, they have been sought after by many young consumers, and the sales of the products have naturally risen. For frameless doors, what else is there in everyone's perception besides handsome?Regarding this issue, maybe everyone hasn't thought about it, but just thinks it's handsome and it's over. 
In fact, there are always two sides to everything, and the same is true for frameless doors, there are disadvantages and advantages, "plus" is handsome and enhances the permeability of the car, other than that, there seems to be no other advantages. Because the frameless door has no door frame, so the requirements for the manufacturing technology, glass, sealing and other aspects of the door are very high, any link has a deviation, then the frameless door has many drawbacks, such as the structure of the door glass is not fixed enough, then the sealing is very bad, there is a large wind noise, water leakage and other shortcomings, plus the glass does not have any frame constraints, then when impacted, the door glass may be directly broken, and the glass of the ordinary door will not be broken. 
In addition, the sealing strip of the frameless door will age relatively quickly, the later maintenance cost is higher, and the installation requirements for the side air curtain are higher. Therefore, in addition to being handsome, the advantages of frameless doors in other aspects are far less than ordinary framed doors. Is the electric suction door practical?
Along with the frameless doors, which have been devolved from high-end luxury models to regular models, there is also an electric suction door function. Previously, millions of car ** people complained on social platforms that the electric suction door was very chicken when it was put on ordinary models, and it was not suitable for ordinary consumers at all. At the same time, many netizens also complained about this, why is this?
First of all, we all know that only luxury high-end models are equipped with electric suction door function, such as Rolls-Royce, Bentley, Mai** and other top luxury cars are equipped, its advantage is that the passenger can maintain an elegant and calm posture when opening the door, which further reflects the identity and style of the passenger. The disadvantage of the electric suction door is that the detection of the blocking is not timely enough, the cost is relatively expensive, the later maintenance cost is high, easy to damage, etc., you must know that the frequency of ordinary consumer cars is very high, the use of scenarios is more and miscellaneous, sometimes accidentally bumped, or the usual car Xi influence, closing the door is more forceful, resulting in the electric suction door is not durable, so that later maintenance is required, directly affecting the consumer's wallet. 
The luxury models equipped with electric suction doors, their owners are generally "rich and multi-billion", and the owner cannot only have one car, the usage rate is not high, and even if the electric suction door is broken, there are drivers to deal with it, no need to worry about it, which is incomparable to ordinary consumers, so some netizens said that ordinary models with electric suction doors are "not the life of the rich, but the disease of the rich". Are electric doors any good?
After talking about the electric suction door, how can you not talk about its good brother electric door?Electric door, that is, induction automatic door, is derived in recent years from the advanced configuration, is composed of door opening actuators, electric suction door locks, radar, ECU and other parts, consumers do not need to manually push and pull, can be through the smart key, the control button of the door and the control button of the door and other ways to carry out electric and remote control opening, before it was generally a luxury model, or MPV models are equipped, and now many flagship new energy vehicles are also matched. 
Originally, the electric door is a very cool and convenient configuration, but because the induction configuration on the door is very harsh on the surrounding scene, there can be no obstacles around the vehicle, and the electric door will only open a little when parking too close to the vehicle or the wall, and can only be opened manually. Sometimes the electric door will also be very "sensitive", the user does not plan to drive, but when he is just close to the vehicle, the door opens automatically, such as Zhiji Automobile, its spokesperson Tang Wei said that he likes the configuration of the electric door very much, but when she washes the car, the vehicle often opens the door automatically, which will not only affect herself, but also cause the car wash water to enter the car, which is a very embarrassing thing. 
Therefore, when auto companies match their products with electric doors, they should take these problems into account and make improvements, so as to improve the convenience of users using vehicles and avoid the above-mentioned situations. Finally, I have to mention a cliché configuration - hidden door handle, which is the mainstream configuration of today's new energy models, we have previously published a detailed draft of hidden door handles, here we will briefly talk about its advantages and disadvantages. 
The advantage of concealed door handles is that they can enhance the appearance and temperament of the doors, as well as the whole car, making the car look more high-end, while also reducing wind resistance;The disadvantages are high cost, high failure rate, and large hidden dangers, such as vehicle collisions, hidden door handles cannot be opened, resulting in the loss of optimal rescue time;In the rain and snow weather in the north, the door is frozen, and the hidden door handle cannot be popped out, which not only makes the user overwhelmed, but also may damage the telescopic mechanism, etc., it can be said that the current design of the hidden door handle does more harm than good. Editor's summary
When some luxury high-end models are delegated to ordinary models, or some innovative configurations, can be imitated by many car companies, and become the mainstream of the market, many manufacturers are for cool, good-looking, and high-quality, so as to attract consumers to match, which will not only sacrifice the user's sense of experience, but also make the brand's reputation outweigh the loss. It would be even better if manufacturers could think from the consumer's point of view and improve the ease of use of these configurations. So the question is, which design or configuration has a larger slot, frameless doors, electric suction doors, electric doors and hidden door handles?
