Vehicle oil tank protecting structure

Abstract

The invention discloses a vehicle oil tank protecting structure which comprises a vehicle oil tank. A protecting box is arranged outside the vehicle oil tank. Baffles are arranged outside the protecting box. Each baffle comprises a pressure-resistant plate. A clamping plate is arranged on the inner side of each pressure-resistant plate. The baffles are connected with the protecting box through buffer pieces. Each buffer piece comprises a cylinder. A groove is formed in the outer wall of each cylinder. A slide way is arranged on the inner wall of each cylinder. Clamping bases are arranged at the left end and the right end of each slide way. First springs are arranged on the inner sides of the clamping bases. Clamping blocks are arranged on the inner sides of the first springs. Sliders are arranged on the inner sides of the clamping blocks. A connecting block is arranged in each cylinder and connected with the corresponding sliders through connecting rods. By means of the vehicle oil tank protecting structure, through the cooperation of the protecting box, the baffles and the buffer pieces, the vehicle oil tank can be well buffered in accidental collision, it is avoided that the vehicle oil tank is prone to damage in accidental collision, and unpredictable dangers are avoided.

[0003] At present, the safety of the fuel tank of passenger cars has attracted the attention of the entire industry and the country when an accident occurs, because in an accident, once the fuel tank ruptures due to severe impact and catches fire, it will have serious consequences and even cause the car to be destroyed. The passenger car safety standard stipulates that the fuel tank must be placed behind the center of the front wheel. In the past, the industry used to arrange the fuel tank in front of the front wheel in order to occupy the least space in the luggage compartment. Now it is arranged behind the center of the front wheel and needs to be placed in the original luggage compartment. Separately draw the fuel tank compartment to ensure that the vehicle has a sufficient buffer area to ensure the safety of the fuel tank when the vehicle is subjected to a frontal collision, but this structure does not guarantee the safety of the fuel tank when the vehicle is subjected to a side collision. Yes, but the distance between the fuel tank and the sides of the vehicle body has not changed, especially now that due to the demand for cost and lightweight, more and more fuel tanks are made of plastic materials, which have weaker shock absorption capabilities, such as the patent No. 201520395731.0 , including the base assembly used to carry the fuel tank, the protective frame assembly welded on the base assembly to protect the fuel tank, and the slide rail fixed on the vehicle body. The slide rail is arranged along the width direction of the vehicle body, and the base assembly and the slide Rails form a sliding fit. Although the safety of the fuel tank is guaranteed to a certain extent, its cushioning capacity is poor, and the impact resistance is poor, so it cannot protect the fuel tank well. The fuel tank is easily damaged when an accidental impact occurs, resulting in unpredictable dangers.
