It is equipped with 17-inch alloy wheels. The K4 offers three rim styles depending on the configuration, while there are also differences in tire size.

The low-spec model uses 205 60 R16 tyres, while the high-spec model uses 215 50 R17 tyres.

Cars with two sunroofs have Teana, Mercedes, Crown, Lexus, etc.

Disadvantages of panoramic sunroofs.

1. Poor sunscreen effect.

The wide glass of the panoramic sunroof can be exposed in the summer, just like the front windshield, which can become a major source of sun exposure, although there are also internal shields that can be pulled on, or put on sunscreen films, but the effect is far less effective than the traditional roof insulation.

2. Troublesome maintenance.

The panoramic sunroof has a large area, compared with a single sunroof, once it is dirty, it will be very obvious, which affects the appearance of the car, but it is very inconvenient to clean. Because the guide rails and sealing strips are longer, the dust and dirt in the gaps are not cleaned thoroughly, and it is easy to open the sunroof function and sealing, and it may leak rain after a long time.

3. Noise is prominent.

The roof of the car is soundproofed cotton, so that the wind noise, raindrop sound will be weakened by the filter of soundproof cotton, the ordinary single sunroof area is small and has little impact on the car, but the panoramic sunroof is equivalent to canceling most of the soundproof cotton on the roof, no matter how good the sealing is, the noise will bring a relatively poor riding experience.

Do you have to be able to open both?

There are many Mercedes-Benz, Crown, Lexus, etc., as well as commercial vehicles.

Cars with two sunroofs have Scorpio, Mercedes, Crown, Lexus, etc. The wide panoramic sunroof glass can reveal serious shortcomings in the summer. Just like the front windshield, it will be the main source.

Although there are also protective cloths that can be pulled up or attached to the sunscreen car film, the effect is far less than that of traditional roof insulation.

The sunroof of the car is installed on the roof, which can effectively circulate the air inside the car and increase the entry of fresh air air. At the same time, the sunroof of the car can also broaden the field of view and meet the shooting requirements of mobile photography. Car sunroofs can be roughly divided into:

Sliding, Built-in, Built-in, Panorama and Curtain Style. It is mainly installed in commercial SUVs, sedans and other models.

Defogging with a sunroof is a quick way to defog. It is especially cautious in summer and autumn, when there is a lot of rain and high humidity. Anyone who drives knows that if you close the side window when driving, the temperature difference between the inside and outside of the car will increase, and the front windshield is easy to form fog.

While most cars are equipped with anti-fogging devices, some effects are not as noticeable. The driver only needs to open the roof sunroof to the rear-ventilated position to easily remove fogging from the front windshield and ensure the safety of the road. When using the sunroof for ventilation, you don't have to worry about the outside environment being harsh and dirty, and you don't have to worry about rain being blown into the car.

Millions of car purchase subsidies.

Cars with two sunroofs have Ethereal, Mercedes-Benz, Crown, Lexus, etc., the wide glass of the panoramic sunroof will expose serious drawbacks in the summer, just like the front windshield, Juega will become the main source of sun exposure, although there are also internal shielding cloths that can be pulled on, or pasted with sunscreen car film, but the effect is far less good than the traditional roof insulation effect.

The car sunroof is installed on the roof of the car, which can effectively circulate the air in the car and increase the entry of fresh air, while the car sunroof can also open up the field of vision and mobile photography and video shooting needs. Automobile sunroofs can be roughly divided into: sliding outward, built-in, built-in and outward-turned, panoramic and curtain types.

The main suspicion is to be installed on commercial SUVs, sedans and other models.

Using a sunroof to defog is a quick way to defog. Especially in summer and autumn, there is a lot of rain and humidity. Anyone who drives knows that if the side window of the car is closed during driving, the temperature difference between the inside and outside of the car will increase, and the front windshield is easy to form fog.

Although most cars are equipped with anti-fogging devices, some are not as effective. Drivers only need to open the roof sunroof to the rear-tilted ventilation position, which can easily eliminate the fog in the front windshield and ensure driving safety. Hungry hands use the sunroof to ventilate, neither have to worry about the harsh and dirty environment outside the car, nor do you have to worry about the rain being blown into the car.

1.Built-in ordinary electric sunroof.

The built-in ordinary electric sunroof is mainly composed of sunroof frame assembly, glass assembly, sunshade assembly, mechanical group assembly, driving mechanism, wind shield assembly, etc., and the sunroof frame assembly includes front beam, aluminum rail, middle beam, drainage groove, etc. The common front beam structure has perforated type and copper tube overmolded type, and the perforated front beam is light in weight and low in part cost, but the mold is more complex.

Hemming molding involves hemming of glass, glass frame and edging material through an injection molding machine, and the sealing strip is snapped to the edging material, which can be divided into half-wrapping and full-wrapping processes. The all-inclusive process completely encapsulates the glass frame through edging, exposing only the connection with the mechanical assembly, and the glass assembly formed by this process is more beautiful, but also heavier. The edging materials are PU (polyurethane), PVC (polyvinyl chloride), etc., and the sealing strip is commonly EPDM (ethylene propylene diene monomer).

According to experience, PVC is not compatible with EPDM materials, and the sunroof is prone to the risk of abnormal noise, so it is recommended to choose PU for edging materials. The paste molding process bonds the glass to the glass frame, and the sealing strip is snapped between the glass and the glass frame, which eliminates the need for hemming molds and lowers the cost.

2.Panoramic sunroof that can be opened.

The openable panoramic sunroof is mainly composed of sunroof frame assembly, glass assembly, sunshade assembly, mechanical unit assembly, windshield net assembly, sealing strip, glass motor, sunshade motor, etc., as shown in Figure 2. The sunroof frame assembly mainly includes the front beam, the rear beam and the aluminum rail, and the frame rubber strip is generally snapped inside the sunroof frame to play the role of shielding. The total composition of the glass is mobile glass and fixed glass, and 4mm thick tempered glass is commonly used, and the molding process is similar to that of ordinary skylights.

The sunroof sunshade is divided into a scroll type and a shaftless type, which can be shaded and insulated after being closed, and the panoramic sunroof is often matched with a roll-type sunshade. In the process of closing the sunshade, the sunshade motor drives the curtain fabric, thereby driving the scroll to rotate, and then driving the torsion spring in the scroll to rotate to accumulate elastic potential energy; In the process of opening the sunshade, under the action of the torsion spring, the reel is driven to reverse to realize the winding of the cord, and the torsion spring releases elastic potential energy. The sunroof sunshade should be pre-tightened in front of the rear beam to ensure that the sunshade is fully opened, and the curtain should be tightened to avoid wrinkles.

According to the different shading rates, the cord can be divided into full shading (more than 99% shading rate) and semi-shading curtain (95% shading rate, 90% shading rate, etc.).

In order to avoid wrinkles in the curtain fabric, it is necessary to wear an anti-detachment structure, mainly including ultrasonic welding PDF (prevent derailing function), sewing guide strip (Teflon TPO), etc., as shown in Figure 3. Ultrasonic welding PDF fabric occupies less space, has less impact on head space, and has lower cost; Sewing Teflon fabrics occupy medium space, medium headroom impact, and medium cost; Sewing TPO fabrics occupy a large space, have a large impact on head space, have a higher cost, and are stronger.

The car sunroof has a panoramic sunroof and a semi-automatic sunroof, the panoramic sunroof is that after the button is opened, the front and rear rows can see the sunroof, and the semi-automatic sunroof can only be exposed half, the front passengers can see it, but the rear passengers can't see it.

Built-in ordinary electric sunroof, openable panoramic sunroof.

1.Manual sunroof, the advantage of this sunroof is that the structure is simple, and there is no complex slide structure, there is no wear and maintenance, only need to pay attention to the aging of the sealant strip regularly. 2.

Sliding sunroof, most of the sunroofs equipped with this structure are forced to do so, probably because the interior space is too small, the arc of the roof is too old, and the roof structure is too old to ideally store the sunroof into the roof mezzanine. 4 shutter type, this kind of skylight also belongs to the large-area skylight that can be opened from the classification, but its opening mechanism is very unique, it can be folded up like the shutter school Jiansheng, and it looks dazzling when operating.

The main function of the sunroof is to enhance ventilation, and there is no need for a sunroof if you do not smoke in the car or need continuous ventilation in the car.

A sunroof is good for enhancing ventilation and increasing daylight, but it can affect the safety of the car, especially the roof.

Because the roof is originally a single piece, the installation of a sunroof in the middle will inevitably impress the integrity of the roof.

Car sunroofs have three main functions:

1. Easy ventilation: Generally, there is no sunroof in the car, in case of air pollution in the car, such as smokers, mildew in the car in spring and summer, etc., the method of opening the side window is often used to ventilate the car, although this method is effective, but also brings adverse effects to the passengers in the car. In the vehicle driving, the airflow flows rapidly inside the sunroof, and the negative pressure is formed on the sunroof to pump away the dirty air in the car, and there will be no large amount of dust and pollution from the front car directly from the side window.

2. Ease of ventilation: The ventilation of the car sunroof has little effect on the temperature change in the car, does not affect the role of the air conditioner and heater in the car, and can make the air conditioner more uniform and soft.

3. Driving safety: driving for a long time, the oxygen in the closed compartment is reduced, the carbon dioxide increases, which is easy to make the driver drowsy, and the sunroof is opened for ventilation, which can make the air in the car fresh, especially the fresh air on the upper layer can make the driver's head and stay awake, and the driving is safer and more reliable.

There are pros and cons to having a sunroof, and the model with a sunroof has a relatively high light transparency rate and a strong ventilation capacity. However, the dead weight of the vehicle with a sunroof will also increase, which will increase the fuel consumption of the car to a certain extent.

First of all, after the car is equipped with a sunroof, the lighting area in the car is larger, which can make the car more transparent, and passengers will not feel particularly depressed when riding.

Secondly, the skylight can also play the role of ventilation.

When the car is driving at high speed, it can be ventilated by opening some gaps in the sunroof, and it will not affect the stability of the vehicle.

However, models with sunroofs also have some drawbacks, such as increased vehicle weight, destruction of roof rigidity, etc.

Moreover, a car with a sunroof is about 1-20,000 yuan more expensive than a model without a sunroof, but the utilization rate of the sunroof is not high.

When buying a car, the owner can choose whether to buy a rotten beam model with a sunroof according to his actual needs.

If the car is smaller than the vertical excavation, you can buy a model with a sunroof to increase the daylight rate and make the space less oppressive.

If the car is larger, there is no need to buy a model with a sunroof.

Of course, some car tuning factories can also provide sunroof installation services for cars, but the quality is uneven, and car owners must keep their eyes open when modifying sunroofs.

Millions of car purchase subsidies.
