Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to an amphibious vehicle capable of traveling on water and on land.

0002

[Conventional technology]

In recent years, the lower part of the vehicle body has been made into a watertight boat structure, making it possible to drive on water. Amphibious vehicles are being developed. This type of amphibious vehicle can move freely on water. Do not expose the cabin, doors, engine, other auxiliary equipment, electrical equipment, etc. The entire body is designed to be watertight to protect it from water damage, and the underside of the body has a bow that is advantageous for traveling on water. The bottom of the rear body has a screw for navigation and a screw for driving. It is constructed with wheels.

[Problem that the idea aims to solve]

However, if a door is installed on the side body of an amphibious vehicle, high-speed navigation (20 ~30 knots), water easily enters through the door seal, causing damage to the door and side body. There was a problem in that the joints caused turbulence and impeded the flow of water. Also, considering the ease of getting on and off the amphibious vehicle, it is possible to open the door at the bridge and enter the cabin. It is not easy to open the door and escape in case of an emergency. A stop is being considered.

0004 Also, considering the case where a screw is used, stable and efficient propulsion force can be obtained. In order to ensure that This would require the steering system to be set at a fairly low position. in a position like this In order to install the screw and steering device and make it possible to run on the ground without any obstacles, The vehicle height naturally increases, and even if it is equipped with doors, it is difficult to get in and out of the vehicle. It will be quite low.

[0005] The purpose of this invention was to use water jet propulsion as a propulsion source for amphibious vehicles. The height of the vehicle is lowered, and entrances and exits for the amphibious vehicle are formed in other parts of the vehicle body except for the parts that come in contact with water. The aim is to provide a fully equipped amphibious vehicle.

[0006] Related technology is "Small ships made of fiber-reinforced plastic equipped with inboard and outboard engines" (Special No. 56-28074) is known, but this proposal raises the above-mentioned problem. But it also doesn't have the structure to solve it.

[0007]

[Means to solve the problem]

In order to achieve the above purpose, the rear of the cabin was opened to provide a boarding gate for the crew. The center frame inside the cabin is opened along the length of the vehicle to allow access from the boarding gate to the driver's seat. In addition to providing a series of passageways from the rear panel to the boarding gate above, The steps are shaped like steps for getting on and off the rear body, and the upper A recess for locating and accommodating the ejection part of the propulsion device is formed along the vertical direction. , the ejection part of the water jet propulsion machine is surrounded in this recess, and one of the above steps is carried out. It is provided by fitting box-shaped frames to form the section.

[0008]

[Effect]

The amphibious vehicle according to the present invention does not use a screw, but instead uses a water jet. Adopts a tarjet propulsion machine, and its ejection part is housed in a box-shaped frame. I am trying to install it. For this reason, structurally speaking, it is difficult to jump stones when driving on land. Easily trim tabs for directional control, propulsion efficiency during water navigation, etc. You will be able to set it. Compared to conventional amphibious vehicles propelled by a screw, the vehicle height is In particular, running stability on land can be maintained at a constant level. Also, the rear body has a If a boarding gate is formed on the back side of the rear passenger seat, the floor of the rear body will be The client side exists in the form of a deck. Therefore, there is no launching from the rear, making it safe. Navigation becomes possible.

[0009] Access to and from the cabin is via steps, boarding gates, and aisles. That is, On land, use all the steps, including the steps on the rear panel, and on the bridge , use the front step of the rear body instead of the rear panel step do.
