What is the rear fender of a car
The baffle structure under the trunk
Definition and location
The rear panel of a car (also known as the rear guard) is a baffle structure located beneath the trunk, on the inner side of the rear bumper, and is connected to the bottom plate of the trunk and the water channel. Its specific location can only be seen after disassembling the rear bumper. It is usually composed of multiple pieces rather than a single whole.
Features and characteristics
Youdaoplaceholder0 Structural function : To separate the outside of a motor vehicle from the inside of the trunk, similar to a "room partition".
Youdaoplaceholder0 Safety function : Absorbs impact force in the event of a collision to reduce harm to occupants.
Youdaoplaceholder0 Materials and design : The original rear panel is mostly made of stainless steel or welded steel plate, which is welded to the frame and is not an integrated structure.
Maintenance Notes
Youdaoplaceholder0 Minor damage : Sheet metal repair (knocking, stretching, etc., non-cutting methods) is preferred to avoid being identified as an accident vehicle and has a small impact on the value of used cars.
Youdaoplaceholder0 Severe damage : If cutting and replacement are necessary, the solder joints must be treated for rust prevention (protected with glue), otherwise they are prone to rust and affect the condition of the vehicle.
Youdaoplaceholder0 Performance impact : Deformation of the rear panel has little effect on handling performance, etc. Safety should be the top priority in repair.
Related concept distinction
Youdaoplaceholder0 Rear guard : Often used interchangeably with the term "rear guard", but some sources emphasize it as a "tail guard" or an arc-shaped design with the manufacturer 's logo in the center.
Youdaoplaceholder0 Spare tire floor : Adjacent to the rear fender, deformation also has minimal effect on vehicle performance.
Youdaoplaceholder0 Summary : The rear panel is one of the more functional components of the body panel, and the repair strategy directly affects the residual value and safety of the vehicle. The appropriate repair method should be selected according to the degree of damage.
The rear panel of a car is an important component located at the rear of the vehicle trunk. Its specific functions can be summarized as follows:
Safety protection and collision energy absorption
Youdaoplaceholder0 Absorbing impact force : In rear-end collisions and other traffic accidents, the rear panel, as the first component to be affected, disperses and absorbs impact energy through its own deformation, reducing direct damage to the passenger compartment.
Youdaoplaceholder0 Protect trunk items : As a barrier between the trunk and the exterior of the vehicle to prevent direct damage to trunk items from external impact.
Structural support and body integrity
Youdaoplaceholder0 Keep the body shape : The rear panel is connected to the body floor, trunk and other components, providing local structural support and maintaining the overall rigidity of the vehicle.
Youdaoplaceholder0 Body panel function : It is a body panel that, although not a core load-bearing structure, is welded to the original frame and plays an important role in aesthetics and sealing.
Dust, WATER and aesthetics
Youdaoplaceholder0 Isolating external environment : To prevent mud, water and debris from entering the trunk and keep the vehicle clean.
Youdaoplaceholder0 Appearance coordination : Together with the rear bumper, taillights and other components, it forms a smooth shape at the rear of the vehicle. Deformation or damage will affect the appearance.
Repair and Used car value impact
Youdaoplaceholder0 Repair method Key : Minor damage can be repaired by sheet metal (not cutting) to avoid being identified as an accident vehicle; Severe damage requires cutting and replacement, but it will cause the vehicle to depreciate and may affect the structural strength.
Youdaoplaceholder0 Key points of inspection for used cars : Deformation or repair marks on the rear panel are one of the bases for determining whether a vehicle has been involved in a major accident.
Youdaoplaceholder0 Summary : Although the rear panel may seem simple, it integrates multiple functions such as safety, structure and protection. The design materials (such as stainless steel, aluminum alloy, etc.) and repair methods need to be carefully treated.
