The function of a bumper is to absorb and mitigate external impact forces, protecting the front and rear parts of the vehicle body, serving as a safety device. Bumpers have the capability to reduce injuries to occupants during high-speed collisions and are increasingly designed for pedestrian protection. In addition to maintaining their original protective functions, the front and rear bumpers of cars also aim for harmony and unity with the vehicle's styling and pursue lightweight design. The front and rear bumpers of cars are made of plastic, commonly referred to as plastic bumpers. Typically, a car's plastic bumper consists of three parts: the outer panel, cushioning material, and crossbeam. The outer panel and cushioning material are made of plastic, while the crossbeam is formed by stamping cold-rolled steel sheets into a U-shaped channel; the outer panel and cushioning material are attached to the crossbeam.

What does the tc slash displayed on the vehicle mean?

When the vehicle displays a tc slash, it indicates that the traction control is turned off, where 'tc' stands for the traction control system. When the ABS anti-lock braking system detects wheel slippage, the traction control system applies braking to the slipping wheel to prevent loss of traction. When the system is active, the yellow 'tc' indicator light on the dashboard flashes to alert the driver. The function of the traction control system is to ensure the vehicle achieves optimal traction under various driving conditions. If the driver accidentally turns off the traction control switch next to the gear lever, the indicator light will also illuminate. If it is confirmed that the switch was not accidentally pressed, it indicates a fault in the traction control system.
