Three aspects to see the highlights of electric vehicle chassis technology

The history of human development has a history of about 1.7 million years since the primitive society. The development of chassis technology for automobiles can be minimal compared to the history of human development, but it has a history of more than 100 years. The technology of the various dish systems, including brakes, suspensions, steering, transmissions, etc., is now quite mature.

And what are the developments and changes in the chassis technology of electric vehicles? The electric car itself is a huge technological development, people get rid of the traditional car power and turn it into electric. Its chassis technology can be said to be a combination of old and new. What are the new ones?

First, the electric control moves. A car brake system is a series of specialized devices that apply a certain amount of pressure to a certain part of the car, mainly to the wheel. Mainly to ensure safety and change the speed of the car. Unlike traditional car brake systems, electric vehicles do not use the motor as a vacuum source, so the brake boost is naturally a difficult point.

The broader solution today is to use a vacuum booster as a power-assisting actuator and an electric vacuum pump as a source of vacuum, but this has some drawbacks. Thus, a new source of power, electricity, began to be adopted. The famous auto parts supplier Bosch, the company introduced an electric mechanical booster - iBooster. The invention of this auto parts brought many new functions that can be intelligentized. It uses electronic technology to achieve braking through electronic control. Its reaction time is also three times faster than the traditional car brake system.

Second, the steering mode is selected. The steering system of a conventional fuel vehicle requires the engine to be driven to provide hydraulic assistance. But now fuel cars are already electric power steering, that is, EPS, EPS is very important for electric vehicles. With the EPS with ECU controller, active control can be achieved, that is, the driver does not need to control the steering wheel to allow the car to automatically turn.

Features such as automatic parking can be implemented and these features are innovative. The steering wheel is an important part of the driver's driving of the car, and is an important tool for the driver to sense the driving condition of the vehicle while driving the vehicle. Different drivers may have different requirements for the steering wheel, but in general they all want to be light and not lightweight, that is, they can know some road feelings. This feature really adds to the car's personal choice.

Third, a highly controllable suspension. When encountering uneven roads, the driver may have had the hope that the chassis of the car can be adjusted according to the level of the road. For electric vehicles, the water repellency of the motor is better than that of a conventional engine. In the modification market, there have been pneumatic suspensions that can achieve active control of lifting.

It mainly uses the electric control air pump to inflate or deflate the airbag to achieve the lifting height and the lowering of the suspension height. However, this method will destroy the interior shape and interior parts of the original car. On the basis of the intelligent large screen, an electronically controlled pneumatic suspension is further configured, in fact, the suspension height can be adjusted.

WiFi 6 Outdoor Wireless AP

The WiFi 6 Outdoor Wireless AP is a wireless access point for outdoor environments that uses the latest WiFi 6 technology to deliver higher speeds, more capacity, and better performance. The benefits of WiFi 6 Outdoor Wireless AP are described in detail and analyzed in depth below.

First, higher speed:
WiFi 6 Outdoor Wireless AP uses the latest 802.11ax standard to support higher data transfer rates. Compared to the previous WiFi 5 technology, WiFi 6 can achieve higher peak speeds, up to 10Gbps. This means users can enjoy faster download and upload speeds, smoother online gaming and high-definition video viewing experiences.

Second, larger capacity:
The WiFi 6 Outdoor Wireless AP uses OFDMA technology to divide wireless signals into multiple sub-channels to serve multiple devices at the same time. Compared to the previous WiFi 5 technology, WiFi 6 can connect more devices at the same time, providing greater network capacity. This is important for modern homes and businesses as the number of devices we have increases and the demand for network capacity increases.

Third, better performance:
The WiFi 6 Outdoor Wireless AP introduces an improved version of MU-MIMO technology that can communicate with multiple devices simultaneously. This means that users can enjoy a more stable and reliable wireless connection, whether in a home environment or an enterprise environment. In addition, WiFi 6 also introduces BSS Coloring technology, which can reduce interference between neighboring networks and improve network performance and throughput.

4. Lower latency:
The WiFi 6 Outdoor Wireless AP uses Target Wake time (TWT) technology to synchronize the wake time of the device with the time of the wireless transmission. This means the device can wake up quickly when it is needed and go to sleep when it is not, reducing latency in wireless transmission. This is important for real-time applications, such as online gaming and video conferencing, to provide a better user experience.

Five, better security:
WiFi 6 Outdoor Wireless AP introduces the WPA3 security protocol, which provides stronger encryption and authentication mechanisms to protect users' wireless networks from hackers and malicious attacks. In addition, WiFi 6 also supports more security features such as encryption for OFDMA and MU-MIMO, as well as stricter access control and user authentication.

Six, better coverage:
The WiFi 6 Outdoor Wireless AP uses more advanced antenna design and signal processing technology to provide wider wireless coverage. This is very important for outdoor environments, which can cover a larger area and meet the needs of users for wireless networks.

In summary, the WiFi 6 Outdoor Wireless AP offers higher speeds, more capacity, better performance, lower latency, better security, and better coverage. It is an advanced wireless access point for outdoor environments that can meet the needs of users for high-speed, high-capacity, high-reliability wireless networks. As the number of Wireless devices increases and the requirements for network performance continue to increase, WiFi 6 Outdoor Wireless AP will become an important part of the wireless network of the future.
