Description

  The present invention relates to an amphibious vehicle.

The amphibious vehicles currently used mainly for tourism are equipped with two engines, one for land operation and one for water operation. The engine can be switched between running on land and running on water. Have been used. This is because the environmental standards for automobiles related to exhaust gas differ from the environmental standards for ships running on the water, and the complex structure when one engine is used for both land and water is disliked. ing.
An example of a technology related to an amphibious vehicle is described in Patent Document 1.

JP-A-2006-175383

  However, if two engines for land operation and two for water operation are provided, the two heavy and heavy engines increase the weight and cost, and the switching operation of the engine becomes complicated. There is a point. In addition, while turning using the rudder on the water, the difficulty in maneuvering by manipulating the rudder at that time and the complexity of certification registration procedures for vehicles and ships due to amphibious use are also hindering popularization. .

  The present invention has been made in consideration of such circumstances, and can be easily switched between on-shore operation and on-water operation, and is easy to turn during on-the-water operation. The purpose is to provide an amphibious vehicle that can travel and contributes to energy conservation and can be registered simply because it is not involved in emission regulations.

  In order to solve the above-described problems, an amphibious vehicle of the present invention includes a land vehicle engine for land travel, an electric motor for water travel, and a storage battery on a vehicle body, and the electric motor includes a propeller shaft. An amphibious vehicle with a propeller connected to the vehicle through which an electric propulsion device is formed, and the electric power generated by the traveling of the land vehicle engine is charged to the storage battery when traveling on land, and the electric motor power when traveling on the water It is used.

  On land, the vehicle is driven by the power of a land-based automobile engine, and on the water, the vehicle is driven by an electric propulsion device. Therefore, switching between land operation and water operation can be easily performed. Further, since traveling on water is performed by an electric propulsion device, exhaust gas is not exhausted at all on the water, and the water surface is not polluted, and quiet traveling is possible. Therefore, it is not affected by exhaust gas regulations.

  Furthermore, since the electric power generated by the traveling by the land vehicle engine during the land traveling is charged in the storage battery and used as the electric motor power during the water traveling, the frequent charging operation of the storage battery can be simplified.

  In the amphibious vehicle of the present invention, two electric propulsion devices are provided on the left and right sides of the vehicle body, and the electric propulsion device can be turned on the water by controlling the magnitude and direction of the thrust. Can do.

  By electrically controlling the magnitude of the thrust and the direction of thrust of the two electric propulsion devices that are equipped with the two, it is possible to accurately perform turning and on-site turning while proceeding.

  According to the present invention, it is possible to easily switch between on-shore operation and on-water operation, easy to turn at the time of on-the-water operation, and can run quietly without polluting the water surface, contributing to energy saving, An amphibious vehicle capable of simple registration can be realized because it is not involved in emission regulations.

It is a figure which shows the structure of the amphibious vehicle which concerns on embodiment of this invention. It is a figure which shows the use condition of an amphibious vehicle. It is a figure which shows the condition of the turning on water. It is a figure which shows the mode of turning by operation of the steering plate as a prior art example.

Below, the amphibious vehicle of this invention is demonstrated based on the embodiment.
FIG. 1 shows a configuration of an amphibious vehicle according to an embodiment of the present invention.
The amphibious vehicle 1 includes a vehicle body 2 and a land vehicle engine 3 and an electric motor 4. A propeller 6 is connected to the electric motor 4 via a propeller shaft 5. Two electric motors 4 to which a propeller 6 is connected via a propeller shaft 5 are provided on the left and right sides of the vehicle body 2 and function as an electric propulsion device 7 that propels the vehicle body 2 on the water. The vehicle body 2 includes a storage battery 8, and the electric power generated by traveling by the land vehicle engine 3 during land travel is charged to the storage battery 8 and used as power for the electric motor 4 during water travel.

FIG. 2 shows a use state of the amphibious vehicle 1.
The amphibious vehicle 1 travels on the land by the power of the land vehicle engine 3, and travels on the water by the electric propulsion device 7. Since running on the water is performed by the electric propulsion device 7, no exhaust gas is discharged on the water. In addition to being able to charge plug-in on land, the land vehicle engine 3 generates electric power when traveling on land, and the electric power is charged to the storage battery 8 for water operation, thereby simplifying frequent charging of the storage battery 8. can do.

FIG. 3 shows the situation of turning on the water.
Two electric propulsion devices 7 for propelling the vehicle body 2 on the water are provided on the left and right of the vehicle body 2 of the amphibious vehicle 1, and as shown in FIG. If it is larger than the thrust of 7b, it turns right while moving forward. Further, as shown in FIG. 3B, by making the left propulsion unit 7a a forward thrust and the right propulsion unit 7b a reverse thrust, the vehicle can turn right on the spot.

  Thus, in the amphibious vehicle 1 of the present invention, it is necessary to operate the rudder at sea by electrically controlling the magnitude and direction of thrust of the two electric propulsion devices 7 installed. The ship can be maneuvered without it.

FIG. 4 shows a state of turning by operating a steering plate as a conventional example for comparison with this.
FIG. 4 (a) shows the time of forward movement. The power of the engine 51 is transmitted through the propeller shaft 52, and a water flow is created by the rotating propeller 53. The strong water flow hits the rudder plate 54, and thereby turns. To do.

  FIG. 4 (b) shows a reverse travel time, and a water flow is created by the propeller 53. However, the water flow does not directly hit the rudder plate 54. Can not. In particular, turning on the spot is impossible. For this reason, it is generally said that a reverse turn is almost impossible for a ship with one propeller and one rudder.

  On the other hand, in the amphibious vehicle 1 of the present invention, the backward turning can be freely performed by the operation of the thrust of the two electric propulsion devices 7 installed, so that the degree of freedom of the turning operation is high.

  As described above, the amphibious vehicle of the present invention travels on land using the power of the land vehicle engine and runs on the water using an electric propulsion device, so switching between land operation and water operation is possible. In addition to being able to easily perform the above, there is a great feature in that the electric power generated by the traveling by the land vehicle engine is charged to the storage battery during the land traveling and used as the electric motor power during the water traveling. Thus, the storage battery is an element that links the land vehicle engine and the electric propulsion device, and has a great technical effect by combining these.

  The present invention can easily switch between on-shore operation and on-water operation, and when turning on water, it is easy to turn, does not pollute the water surface, can run quietly, contributes to energy saving, and discharges. As an amphibious vehicle that can be registered simply because it is not involved in gas regulations, it can be widely used for tourism.
