What is the function of car rain guards?
2 Answers
The functions of car rain guards are: 1. In rainy conditions, they maintain fresh air circulation inside the vehicle to meet human needs; 2. Prevent window fogging that could obstruct the driver's vision and operation, enhancing driving safety; 3. Block side glare and UV rays, reducing interior temperature; 4. Keep rain, snow, and dust out while still allowing air exchange with the outside. Precautions for using car rain guards: 1. Purchase from authorized dealers to ensure quality; 2. Clean the window area thoroughly with a cloth before installation, as excessive dust or debris can weaken the adhesive strength.
The main function of rain guards is to prevent rainwater from directly entering the car during rain, especially when opening the windows for ventilation. They also effectively block sunlight, reducing excessive heat inside the car. I find them particularly practical for daily commutes, such as driving to and from work in the rain—cracking the windows slightly improves airflow without getting the interior wet. Additionally, they prevent rainwater from blurring the view outside the window, reducing safety hazards. In high summer temperatures, they can also indirectly save on air conditioning costs. Some designs even help reduce wind noise at high speeds, making driving quieter and more comfortable. Overall, this accessory is quite thoughtful, easy to install (usually a DIY job), and enhances both convenience and safety. It's definitely worth having a set in your car.
