What is the frame of a car headlight
Youdaoplaceholder0 The headlight frame is the external support and protection structure of the headlight . The following is a detailed explanation of the car headlight frame:
Main function
Youdaoplaceholder0 Protective function : The headlight frame provides the necessary protection for critical components inside, such as the bulb and reflector, against external impact and damage.
Youdaoplaceholder0 Support function : As the skeleton of the headlight, the headlight frame ensures that the headlight can be firmly installed in the vehicle, maintaining its correct position and Angle.
Common materials
Youdaoplaceholder0 Thermoplastics : Automotive headlight frames often use thermoplastic materials such as PC, PBT, and ABS. These materials have high strength, good weather resistance, and dimensional stability, which can meet the requirements of headlight frames.
The relationship with other components of the headlight
Youdaoplaceholder0 Lampshade : The frame of the headlamp is closely connected to the lampshade and together form the external structure of the headlamp. Lampshades are usually made of transparent or semi-transparent materials, such as polycarbonate, which protects the internal components and allows light to propagate effectively.
Youdaoplaceholder0 Reflector : Inside the headlight frame, there is usually a reflector, such as a reflector bowl or mirror, which is responsible for reflecting and concentrating light to enhance illumination.
In conclusion, the frame of a car headlight is an important component of the headlight. It protects the internal components of the headlight, supports the structure of the headlight, and works in coordination with the lampshade, reflective device, etc., to jointly achieve the lighting function.
Automobile HEADlight FRAME FAILURE mainly include the FOLLOWING situations:
Youdaoplaceholder0 Broken or cracked plastic frame : If the plastic frame of a car headlight is broken or cracked, it usually needs to be replaced with a new one. First, check the degree of damage to the frame. If it is only partially damaged, it can be considered for repair. But if most of them are broken, it's best to replace them with a new one directly. When replacing, make sure the purchased frame matches the model and year, and handle with care to avoid damaging other parts .
Youdaoplaceholder0 Bracket broken : Repair of broken headlight bracket may pose a risk and may not ensure driving safety. The repair process is cumbersome and difficult to ensure stability, so replacement is a wiser choice. When replacing, make sure the new bracket is securely installed and does not loosen during driving .
Youdaoplaceholder0 Housing crack : The appearance of cracks in the headlamp housing may be due to low material standards, unreasonable design or external force squeezing, etc. Although polycarbonate materials have good light transmittance and high-temperature resistance, they may crack under the long-term influence of high and low temperature differences, ultraviolet rays and pressure. If there is an external force acting, such as leaning against a car, it can also cause cracking .
Youdaoplaceholder0 Car headlight frame deformation can be repaired by the following methods :
Youdaoplaceholder0 Go to a 4S store or professional repair shop for adjustment : If the headlight frame is deformed and causes asymmetry in the headlight gap, you can go to a 4S store or professional repair shop for inspection and adjustment. The repairman will check the radiator frame and the fir beam for deformation and carry out professional repair to ensure that the headlight is installed in the correct position and the gap is symmetrical .
Youdaoplaceholder0 Adjust headlight height by yourself : If only the headlight height is incorrect, you can use the headlight height adjustment button inside the vehicle to rotate it. These buttons are usually located in the driver's cabin, such as under the steering wheel or on the center console. Rotate the button upwards and the light will adjust downwards. Rotate the button downward and the light will adjust upward. This method works for adjusting the height of the headlight without involving frame deformation .
Youdaoplaceholder0 Adjust the tangent of the headlights : Park the vehicle vertically against the wall in a dark and safe place, with a distance of about 3 meters between the headlights and the wall. Open the engine hood and find the headlight adjustment knob. Usually, the vertical knob is used to adjust the height and the horizontal knob is used to adjust the width. If it is a split headlight, the high beam and low beam need to be adjusted separately .
Youdaoplaceholder0 Dealing with dents : If there is a dent in the headlight frame or bumper, you can try heating the back of the dent with a baking lamp to soften it and then gently press it back into shape. For the dents on the metal casing of the vehicle body, a small rubber-wrapped hammer can be used to gently tap from the back for repair. Take care to control the temperature and strike force to avoid damaging the finish .
