What is the rear tailboard of a car
The car tailboard, also known as the car lifting tailboard, car loading and unloading tailboard, lifting tailboard, hydraulic car tailboard, and truck tailboard, is a hydraulic lifting and handling equipment powered by the on-board battery, which is installed at the rear of trucks and various vehicles. The tailboards of automobiles can be classified as: cantilever tailboards, vertical tailboards, swing arm tailboards, and folding tailboards. The tailboard, as a vehicle-mounted loading and unloading tool, can greatly enhance the efficiency and convenience of loading and unloading.
Whether the rear panel of a car is firm after being cut mainly depends on the cutting range and the repair process. Youdaoplaceholder0 If only the outer iron sheet is cut without affecting the internal structural frame, the vehicle can still maintain good sturdiness; However, if it involves overall cutting or structural damage, it will significantly reduce the strength and safety performance of the vehicle body.
The influence of the cutting range
The rear panel is composed of two layers: the outer layer is covered with iron sheet, and the inner layer is a structural frame. The effect of cutting varies by range:
Youdaoplaceholder0 Only the outer iron sheet is cut : it has a relatively small impact on the vehicle rigidity and does not affect the safety performance because the internal structural frame is not damaged.
Youdaoplaceholder0 involving overall cutting or structural frame : it will undermine the overall strength of the vehicle body, reduce safety, and especially increase the risk in a collision.
Potential risks to security performance
The following problems may arise from the cut panels:
Youdaoplaceholder0 Structural strength decline : The originally intact body structure is damaged, which may lead to weakened protective capabilities during collisions, such as increasing the risk of vehicle breakage in rear-end collisions.
Youdaoplaceholder0 Improper repair of derivative problems : such as poor sealing (water entering the trunk), accelerated rusting, further affecting the service life.
The cutting of rear panels may have the following adverse effects on vehicles:
Firstly, from the perspective of safety performance and handling performance, the cut side panels may reduce the structural strength of the vehicle, making it unable to provide sufficient protection in the event of a rear-end collision, thereby exacerbating the extent of vehicle damage.
Secondly, in terms of the vehicle's retention rate, vehicles with their panels cut off are often regarded as accident vehicles, which is a significant deduction in the second-hand market. Car dealers and consumers generally have doubts about the safety performance, service life and handling performance of such vehicles, which has led to a significant decline in the market value of the vehicles.
Furthermore, the repair of the cut panels may require more complex processes, such as shaping and welding, which not only increases the repair time but also raises the maintenance cost.
Regarding the question of whether the repaired rear panel is considered an accident vehicle, if it must be repaired by cutting, it is usually regarded as an accident vehicle. This will have a further impact on the vehicle's retention rate.
To sum up, the cutting of rear panels may have a long-term negative impact on the vehicle's safety, value retention and maintenance costs. Therefore, when repairing a vehicle, it is advisable to avoid cutting the rear panel as much as possible and choose a more suitable repair method.
Whether the replacement of the panel affects safety depends on the repair method: non-cutting and welding repair (such as knocking, stretching) has a relatively small impact on safety, while cutting and welding replacement may significantly reduce the strength and safety performance of the vehicle body and cannot fully restore it to the original factory level.
The impact of repair methods on security
The rear panel is an important structural component at the rear of the vehicle body, responsible for collision protection. The impact of its replacement on safety mainly depends on the repair process:
Youdaoplaceholder0 non-cutting welding repair (such as sheet metal repair) :
The impact on safety is relatively small: When repaired by methods such as knocking or stretching, the vehicle's frame structure is not damaged. The vehicle's anti-collision capability and rigidity remain basically at the original factory level, and it can still effectively protect passengers in normal collisions.
Applicable scenarios: It is suitable for minor damages (such as small depressions or deformations). After repair, the vehicle will not be regarded as an accident vehicle, and the value loss of the used car is also relatively small.
Youdaoplaceholder0 cutting welding replacement :
High safety risk: The cutting operation will damage the original structure of the vehicle body. The strength and toughness of the welded parts are difficult to meet the original factory standards, resulting in a decline in the anti-collision ability of the rear panel and the surrounding area. In a collision, the impact force cannot be effectively dispersed, increasing the number of passengers
Long-term hidden dangers: Cutting may damage the electrophoretic coating, causing rust problems, and after repair, it is prone to derivative problems such as increased wind noise and reduced sealing performance.
