In recent years, with the improvement of people's living standards, China's car ownership continues to rise, and the safety devices in the car are getting more and more attention. However, most people pay attention to adult protection systems, but only children's safety devices. Very few. Therefore, Gasgoo.com has carried out an inventory of the latest children's safety technology for the reference of parents and friends.

First, child safety lock
Some car owners feel that as long as the car is locked, the central locking is locked or the driving is automatically locked to ensure the safety of the children in the back row. However, since the central locking can be unlocked by the unlocking switch in the car, locking the central locking does not mean that it is foolproof.
In order to ensure the safety of children, parents should lock the child safety locks on both sides of the back door to avoid accidents caused by the child's misoperation during the driving process.
There are two common types of child safety lock switches, one is the knob type (left) and the other is the toggle type (right). Since the knob type child safety lock needs to be inserted into the corresponding hole by using a key (or a key object), the knob switch can be rotated to perform the locking and unlocking operation. In contrast, the toggle child safety lock is easier to use.
Second, electric anti-pinch window
In order to meet the growing demand for driving safety and comfort, electric glass lifts are now almost the basic configuration of the car. At present, more than 80% of passenger cars in China are equipped with electric glass lifts, and this proportion continues to rise. In fact, the emergence of an automatic glass lifter with one-button operation brings more convenience. But what if there is an obstacle between the window glass and the frame – for example, one hand or worse, the child's neck – what should I do?
About 30 years ago, the German Brose Group noticed this problem and produced the world's first electric glass lifter with anti-pinch function. When the system finds obstacles, it can stop the window from rising and immediately reverse the decline, reducing the risk of injury to a minimum. Since then, this technological innovation has been added to the corresponding legal norms, and because of its necessity, many countries have adopted a mandatory regulation. Similarly, Webast, the market leader in automotive sunroofs, has added anti-pinch functions to the sunroof design of cars more than 15 years ago to ensure the safety of drivers and passengers.
Since the beginning of 2012, China has implemented the GB 11552-2009 specification, which requires that the automatic windows/sunlights of new vehicles should have anti-pinch function and the anti-clamping force is less than 100 Newtons. In other words: before the anti-pinch force reaches 100 Newtons, the window must stop rising and fall back in the area where the risk of pinching may occur (the window opening is between 4 and 200 mm). The automatic window without the anti-pinch protection can have a force of up to 400 Newtons when closed, which is equivalent to a weight of approximately 40 kg.
In fact, the anti-pinch function is listed as a product innovation that continuously improves the safety and comfort of the car. Brose revealed that his engineers at the Hallstadt R&D Center have begun work on the development of the seventh-generation anti-pinch system. In this generation, the relay will be replaced by a semiconductor, which not only saves structure and noise, but also accurately monitors the speed of the window lifter motor to more accurately control the anti-pinch function.
In addition, Brose not only applies this knowledge and decades of technology and experience in the field of anti-clamping to side windows, but also has a dedicated team that has invested in high-capacity trunks such as MPV or SUV vehicles. The study has similar functions to the traditional anti-pinch system on the trunk door of these models, such as the anti-pinch system for electric trunk doors.
Third, inflatable portable child seat
In addition to the traditional child safety seat, an inflatable child seat has appeared on the market recently. With the push of a button, the built-in air pump will fill the inflatable seat in 40 seconds and deflate in the same way. It can even be folded and easily inserted into the backpack when it is not inflated.
The seat weighs less than 12 pounds when folded. The air pump in the seat can be remotely controlled via Bluetooth, which means that the user can control the inflation and deflation of the seat through the mobile phone.
It is understood that this seat is in the same level of safety as a traditional child seat and does not reduce safety because it is inflated.
Fourth, children's seat new materials
The foamed polymer E-por material obtained based on various polymers and added with a foaming agent has good elasticity and is also convenient to recycle. Applying this material to a child seat provides better protection for the child's neck and head. Elasticity and shock resistance are several criteria for measuring the safety and reliability of children's seats. E-por materials mix foamed polypropylene and expanded polystyrene in an optimal ratio to be sensitive to the head and neck. The area is effectively protected.
The child seat with E-por material weighs only 10.8 kg, and the 5-point seat belt and anti-tilt system provide a guarantee for the safety and stability of the seat.
Five, adaptive seat belt
Not long ago, an adaptive safety belt designed specifically for children was introduced. This new seat belt significantly reduces the load on the child's body when the seat belt is applied, while also enhancing the protection of adults. Its unique mechanical structure allows for adaptive load changes based on the volume of the wearer's body.
The new belt retractor changes the binding force according to the impact impact force and body volume without any sensor intervention. For large passengers, the sidebands of this seat belt will restrain the passenger's body position in a soft manner, greatly reducing the "rebound effect" that traditional seat belts will produce. A load limiting function is added to the pretensioner to limit the binding of the shoulder straps, thereby reducing the load on the belt neck of the wearer.
The belt retractor is equipped with a spring loaded disc with a large number of teeth on both sides. As the load disc rotates, it automatically combines the optimized slots and locks. The faster the belt is pulled out, the greater the reverse resistance will be applied to the load, ensuring that the child is not exposed to excessive seat belt restraint. [ZJ4]
Six, reversing image / rear view camera
The number of injured people in the United States each year is about 15,000, and the number of deaths is 210. About one-third of the casualties in this type of accident are children under the age of five.
The US Road Traffic Safety Administration (NHTSA) has stipulated that by May 1, 2018, all new cars produced in the United States (for vehicles weighing less than 10,000 pounds, approximately 4,540 kg) will require a rearview camera. . In addition, all trucks and buses in the 2019 model must also come standard with this system.
To this end, a complete vehicle manufacturer recently introduced a new interior rearview mirror that switches between a traditional screen and a liquid crystal screen. The advantage of a liquid crystal display over a conventional screen is that its image is not blocked by objects inside the car like a conventional rear view mirror, such as a C-pillar, a seat headrest, and the like. Especially when there are passengers in the car, the rear passengers will block the visibility of most of the rearview mirrors. Since the liquid crystal display directly adopts the image of the camera behind the vehicle, the rear view of the vehicle can be presented to the driver in an unobstructed view.
In addition, the screens displayed by the liquid crystal rearview mirrors are not affected by environmental factors such as rain and snow, fog, and night. Even if the vehicle is followed by the headlights, the special image decoding program can cope well without image glare.
Summary: Just as drivers can't rely too much on active safety technology, children's ride safety technology can greatly reduce the chances of children being injured while riding, but more importantly, parents need to pay attention to children's safe travel problems and conduct behavior supervision and supervision. correct. From the two aspects of technology and self-regulation, we can ensure the safety of children by car.
