Description

Technical Field

[0001] The utility model belongs to the field of chassis protection, and in particular relates to an automobile chassis protection structure. Background Art

[0002] Off-road vehicles are common nowadays. Due to the particularity of the use environment and working conditions of off-road vehicles, high requirements are put forward for the bottom protection of the vehicle and the rust of the whole vehicle. According to research, most of the losses in the chassis are caused by impact under severe working conditions. Therefore, in order to avoid the impact of the bottom, various models have increased the bottom protection to varying degrees. However, most of the current protective materials use PVC materials, and cast iron plates are used for protection at the bottom. However, this form of protection cannot effectively protect when the off-road vehicle is subjected to a strong impact under severe working conditions. At the same time, the strength of the guard plate is relatively low and cannot provide good protection. Utility Model Content
