The composition of the wiper.
A windshield wiper is a common part of a car used to clear rain and snow and keep the driver's vision clear. It consists of several components, each of which plays an important role.
The first part is the wiper arm, which is the part that connects the wiper blade and the motor. It is usually made of metal or plastic and has a certain strength and durability. The length and shape of the wiper varies according to the design and size of the vehicle
The second part is the wiper blade, which is a key part used to remove rain and snow. Blades are usually made of rubber and have soft and wear-resistant properties. One end of it is attached to the wiper arm and the other end is attached to the window. When the wiper is working, the blade will rub back and forth against the glass surface to remove water droplets
The third part is the motor, which is the power source that drives the wiper arm and blade movement. The motor is usually installed in the engine compartment of the car, connected by a connecting rod and a wiper arm. When the motor works, it creates a rotating force that causes the wiper arm and blade to swing back and forth, removing water droplets from the glass.
The fourth part is the wiper switch, which is the device that controls the wiper. The switch is usually installed on the dashboard next to the driver's seat of the car for easy operation by the driver. By flipping the switch, the driver can adjust the speed and interval of the wiper to adapt to different weather conditions.
In addition to the above main parts, the wiper also includes some auxiliary components, such as the connecting rod of the wiper arm, the joint of the wiper arm and the connecting device of the wiper blade. The role of these components is to make the entire wiper system more stable and reliable.
Wiper is an essential device in the car, its role is to keep the driver's line of sight clear, improve driving safety. When driving on rainy or snowy days, the wiper can quickly remove water droplets and debris from the window, ensuring that the driver can clearly see the road and traffic conditions ahead.
The wiper is an important part of the car, which is composed of the wiper arm, the wiper blade, the motor and the switch. They work together to ensure that drivers can maintain a good line of sight in bad weather and improve driving safety. In daily use, we should regularly check and replace the wiper blade to ensure that it works properly.
