Description

Amphibious vehicle with buoyancy structure to prevent flooding and sinking}

The present invention relates to an amphibious vehicle, and in particular, provides a vehicle body in the form of a bus capable of accommodating a large number of passengers while forming a buoyant body that does not absorb water in the vehicle body so that the vehicle body is damaged or water enters the vehicle body. It relates to an amphibious vehicle having a submersion and sinking prevention buoyancy structure capable of preventing sinking even when water is introduced.

In general, hybrid transportation refers to means of transportation that can simultaneously operate on roads and other traffic routes, and is an amphibious vehicle equipped with a land propulsion device and a water propulsion device to perform driving (navigation) on land as well as on water. This is typical.

In other words, an amphibious vehicle is a vehicle equipped with wheels for driving on land and a floating structure and a propeller for navigating on water, and is capable of both driving on land and smooth navigation on water.

These amphibious vehicles are mainly used for military purposes or as part of personal leisure activities.

Here, for military use, it is possible to drive on land through a floating structure as well as on land by being equipped with a track (caterpillar), but this is for military purposes, mainly to facilitate driving in unpaved or field conditions. It is for

Therefore, military amphibious vehicles have a problem in that driving on paved roads such as asphalt is restricted. That is, since there is a problem that the paved road is damaged, it is limited to military use as a structure suitable for unpaved or field.

In addition, amphibious vehicles used for leisure activities are mainly manufactured in the form of an ATV (All Terrain Vehicle), and are operated on the water, that is, oceans, lakes, rivers and waterways, etc. through a floating hull and driven on roads through wheels. Although this is done smoothly, there is a problem in safety and riding comfort for the purpose of transportation rather than leisure.

This is an open type, and when operating on the water, splashing water causes discomfort such as getting wet clothes, as well as being small, and is affected by waves and currents, resulting in safety problems.

In addition, even when driving on the road, it is an open form, and the driver as well as the passenger must drive on the road in a state of being exposed to danger. There are limits to substituting means.

Therefore, in order to develop an amphibious bus capable of solving the above-mentioned problems, numerous researches and developments are currently being conducted.

On the other hand, there is a possibility that the amphibious bus may be sunk due to an external shock caused by a collision or deteriorating weather conditions during water navigation. When such a sinking accident occurs during water navigation, there is a problem in that it is impossible to escape and it is difficult to expect help from outside.

In order to solve this problem, conventionally, in most cases, a reinforcing material of a thick material is simply mounted on an outer surface of a vehicle body of an amphibious bus to reinforce the vehicle body.

Mounting such a heavy and thick reinforcing material significantly increases the weight of the amphibious bus and consumes a lot of power during operation. there was a problem with the

In addition, the excessive weight of the amphibious bus and the thick thickness of the amphibious bus caused serious damage to the other vessel when colliding with another vessel.

Therefore, in order to effectively prevent damage due to collision and to protect the amphibious bus and passengers from sinking, a technology capable of increasing buoyancy during the manufacturing process of the amphibious bus is urgently required.
