Posture-adjustable amphibious vehicle and posture control method thereof

Abstract

The present invention discloses a posture-adjustable amphibious vehicle and a posture control method thereof. The posture-adjustable amphibious vehicle comprises a vehicle body and a mass center adjusting device, the mass center adjusting device comprises a sliding rail fixedly connected with the bottom of the vehicle body, the sliding rail is in sliding fit with a mass block, and air bags are arranged at the upper end and the lower end of the vehicle body respectively. The invention further provides a posture-adjustable amphibious vehicle posture control method, the posture-adjustable amphibious vehicle posture control method comprises a water posture control mode and a landing posture control mode, and when the target mass center offset or landing inclination angle of the amphibious vehicle is small, adjustment is conducted only through the mass block; and when the target mass center offset or landing inclination angle of the amphibious vehicle is large, the mass block is adjusted, and the anti-rollover airbag or the auxiliary landing airbag is opened at the same time. The amphibious vehicle posture adjusting device is rapid in posture adjustment, large in adjusting amplitude and suitable for various amphibious adjusting working conditions, the weight of the amphibious vehicle is not additionally increased, and the driving stability and safety of the amphibious vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of amphibious vehicles, in particular to an amphibious vehicle with adjustable attitude and a method for controlling the attitude thereof. Background technique [0002] At present, in the world, the safety of van-type amphibious vehicles on water has become a key factor restricting the design of van-type amphibious vehicles. Most of the existing public patents are to add water storage tanks on the basis of the hull, and adjust the quality of the hull by storing water under water conditions. Although the form of water storage can adjust the mass distribution of the vehicle to a certain extent, it has many disadvantages: first, it is only applicable to the adjustment of water working conditions, and cannot be used for land working conditions; second, the adjustment time on water is long, and the system Through the adjustment of the form of water in and out, the reaction cycle is too long, which is not conduciv...

[0002] At present, in the world, the safety of van-type amphibious vehicles on water has become a key factor restricting the design of van-type amphibious vehicles. Most of the existing public patents are to add water storage tanks on the basis of the hull, and adjust the quality of the hull by storing water under water conditions. Although the form of water storage can adjust the mass distribution of the vehicle to a certain extent, it has many disadvantages: first, it is only applicable to the adjustment of water working conditions, and cannot be used for land working conditions; second, the adjustment time on water is long, and the system Through the adjustment of the form of water in and out, the reaction cycle is too long, which is not conducive to rapid response; the third is to increase the water storage function to increase the weight of the hull, which is not conducive to the economy and power of the vehicle

[0003] In addition, the existing amphibious vehicles use the wheel retractable device to achieve water and land working conditions. Due to the structure of the vehicle body and the attitude of the vehicle body on the water, most amphibious vehicles can only achieve shoal landing, and do not have the ability to land vertically on the water
