OK window is popular again, why don't domestic card friends buy it?

As we all know, howo trucks have a lot of blind spots due to their relatively long body size. Many traffic accidents are caused by the blind spots of truck vision, especially when turning right, coupled with the factors of poor inner wheels, pedestrians will be caught if they are not careful. , non-motor vehicles, etc. are involved in the bottom of the vehicle, causing casualties, also known as "the right wheel of death".

So how to solve this problem? What is common in today's cars is a dance camera or a 360-degree panoramic image. In the 1980s and 1990s, when there were no electronic devices, the blind-filling mirror and the blind-filling window at the passenger door were mainly relied on, also known as the "OK" window.

The "OK" window originated in Japan and was first applied by the Japanese Isuzu. It was once popular in Japanese cars, and was widely used in Japanese trucks. It was mainly designed at the passenger door. Why is it called "OK window"? According to rumors, it is actually just to take a second look at the blind window when preparing to start or during driving to ensure that there is no problem with "OK" before starting.

It is more convenient for the driver to sit on the main driver and observe the main driver's side, but the blind spot on the co-pilot's side is too large, especially if he is not careful when turning, an accident will occur. With this small window, the situation on the co-pilot side can be viewed more clearly and directly, improving driving safety.

"OK window" is more suitable for use in roads with complex environments, such as urban roads and construction sites. Therefore, the appearance rate in urban vehicles and engineering vehicles is relatively high. The development of commercial vehicles in my country is also deeply influenced by Japanese heavy trucks. The "OK window" has also appeared on the previous domestic Chunlan trucks.

With the development of various active safety systems, the "OK window" has gradually disappeared, but at the 2018 Hannover Motor Show, sinotruk, Volvo, DAF, Renault and other European giants also exhibited "OK windows". "The tractor.

At present, in China, the HOWO TX dump truck also uses the "OK window". The dump truck needs to enter and leave the construction site frequently and other complex working conditions. Stone, etc., more secure.

It is undeniable that the existence of the "OK window" can indeed reduce the occurrence of some accidents, improve safety, and is very convenient. However, I interviewed several drivers, and some drivers feel that there is still a certain degree of use of the "OK window". doubts and concerns.

First of all, the doors of the truck are designed with reinforcing ribs. If an "OK window" is added to the door, will it affect the strength of the cab, especially in the event of a side impact. And the position of the "OK window" is just under the window, will it also affect the area of ​​the window?

Secondly, because the driver's line of sight is relatively high, the size of the "OK window" is relatively large, and there is still a large visual blind spot, especially near the tires and relatively low obstacles, such as encountering children when turning. And in the process of driving, the side situation flashed by, and it may be too late to see clearly.

Finally, do you have to re-open the mold to use the "OK window"? The mold-opening is an expensive cost for the OEM. Will this part of the cost be transferred to the car purchase cost of the card friends?

In fact, for card friends, there are now more options for card users to reduce visual blind spots, such as four-directional cameras and electronic rearview mirrors.

Nowadays, 360 panoramic image has become an optional configuration for many cars. There is no blind spot in 360 degrees. Whether it is before or during driving, you can observe at any time through the large central control screen, avoid various dangerous factors, and maintain driving safety. With night vision function, it can also act as a driving recorder.

The electronic rearview mirror is a new configuration at present. Although it has not been widely used due to factors such as laws and regulations, actual use restrictions, etc., the visual range of the electronic rearview mirror is larger, which can also reduce visual blind spots and improve driving safety. .

The blind spot of trucks has always been a headache for many card fans. The popularity of the "OK window" can really reduce the visual blind spot. What do you think of this configuration? Does it need to be popular again? Come and share your thoughts in the comment section
