Description

The present invention relates to a camper having a power consuming device, a bed, or the like inside the vehicle.

Conventionally, a container having a power supply facility such as a water heater or an outlet in an internal space, as disclosed in Patent Document 1, for example, is already known. Then, a configuration for stably supplying electric power to these facilities has also been proposed (for example, Patent Document 2).

Japanese Unexamined Patent Publication No. 2013-117133 Utility Model Registration No. 3222644

Here, the inventors thought that it was necessary to have a configuration capable of stably supplying sufficient electric power even in a movable vehicle, that is, a camper.

An object of the present invention is to provide a camper capable of stably using sufficient electric power.

It is mounted inside the main body and includes a lithium iron phosphate type battery set that supplies power to the power consuming tool, and the solar panel member supplies power to the battery set. The power consuming tool is a camper characterized by including an air conditioner used in the living space.

In such a configuration, the power consumed by the power consuming tool provided in the camper can be covered by the iron phosphate lithium-ion battery type battery set. Further, the lithium iron phosphate battery (storage battery) has an advantage that it is smaller than a lead storage battery, for example, and can withstand a large amount of power consumption. Here, since the living space of the camper is much larger than the internal space of a normal private car, the air conditioner used there is also required to have a high output, but by using a lithium iron phosphate battery, It can be fully supported.

Here, conventionally, lead-acid batteries have been widely used, but lead-acid batteries are heavy and large, and have a problem that an electrolytic solution leaks when tilted. In a vehicle such as a camper, loading a heavy object may lead to deterioration of fuel efficiency or hinder the loading of other articles. On the other hand, in the camper according to the present invention, since a small and lightweight lithium iron phosphate battery is used, such a problem does not occur. Further, the lead-acid battery generates heat when it is charged and approaches a fully charged state, and chlorine gas is generated, which may worsen the environment inside the vehicle when used in a camper. However, such a problem does not occur in the lithium iron phosphate battery according to the present invention. In addition, due to the structure peculiar to lead-acid batteries, it could not be used in coastal areas in order to avoid salt damage. However, the camper of the present invention can be used freely. Further, since the lithium iron phosphate battery is small, can withstand a large amount of power consumption, and does not generate heat, it is possible to reduce the cost of attaching a heat insulating material or the like when it is applied to a camper. In addition, lead-acid batteries have a short life due to inefficiency in the relationship between the number of charges and discharges and the depth of discharge, and have the problem of so-called battery exhaustion. , Such a problem can be solved. For example, a lithium iron phosphate battery has the following characteristics.
(Example: Cycle Life> 2000 cycles @ 1C100% DOD)

Further, a bed is provided in the living space, and the bed is provided with a plate-shaped bed portion on the surface side on which the user lies down, and the bed portion is tiltable so as to be in a horizontal position in a used state. The position can be freely changed to an upright position in an unused state, the power consuming tool includes a display device having a horizontally long display screen, and the back surface side of the bed portion is in the longitudinal direction of the bed portion. The display device is provided in a direction that coincides with the longitudinal direction of the display screen.
A configuration is proposed in which the display screen of the display device faces the living space while the sleeper portion is in the upright position.

In such a configuration, the display screen of the display device can be visually recognized by tilting the sleeper portion to the upright position. Therefore, a relatively large display device can be adopted, and the luxury of the interior can be dramatically improved while effectively utilizing the living space of the camper.

Further, it is proposed that the bed is arranged in the upper space of the driver's seat of the vehicle body.

With such a configuration, the display device can be arranged at the front end of the living space long in the front-rear direction, so that the long living space in the front-rear direction peculiar to the camper can be effectively utilized.

Further, it is proposed that the battery set is composed of three lithium iron phosphate batteries, the output of the lithium iron phosphate battery is DC12V, and the required voltage of the air conditioner is DC12V.

With such a configuration, the load on the inverter can be reduced. This also enables simultaneous use with, for example, a microwave oven or an IH heater as another power consuming tool.

Further, the traveling charger is electrically connected to the traveling battery provided in advance in the vehicle body, and it is possible to supply electric power from the traveling charger to the iron phosphate lithium ion battery during traveling. The configuration is proposed.

With such a configuration, the lithium iron phosphate battery can be charged while the camper is running, and sufficient electric power can be immediately supplied while the camper is running or when the destination is reached. Can be done.

Further, it is proposed that an external power source can be connected to the lithium iron phosphate battery, and power can be supplied from the external power source to the lithium iron phosphate battery while the vehicle is stopped.

With such a configuration, when the electric power charged in the lithium iron phosphate battery is insufficient, the electric power can be supplied from the external power source.

The camper according to the present invention has an effect that sufficient electric power can be used stably.
