Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mobile sales vehicle equipped with a rechargeable/dischargeable power supply device.

[Conventional technology]

Traditionally, businesses have operated in a passive manner, with fixed stores and waiting for customers to come and buy their products, but in recent years, sales have been actively conducted using mobile sales vehicles that have been modified from cars. methods have also begun to be used.

However, in this case, how to use the power source becomes a big problem that needs to be solved.

In other words, a car only has an extremely small-capacity power generation device that is sufficient to satisfy its original functions, so if this car is modified to become a multi-purpose vehicle such as a mobile sales vehicle, it will naturally lack the power generation capacity. There are many cases. Furthermore, even if an attempt is made to increase the capacity of a car's generator, since it is driven by the car's engine, there is a limit unless the car's engine is replaced.

Because of the above, when the power capacity of a mobile sales vehicle cannot be covered by the vehicle's original power generation capacity, conventionally, a small motor-driven generator is installed independently and the insufficient power is generated by this generator. If there is a supplementary method (independent generator system), or if the car's engine has enough power, the engine can directly drive the hydraulic pump, and after smoothing out the hydraulic pressure generated by this hydraulic pump, the hydraulic motor can be driven. A method (hydraulic power generation method) was used in which the engine was driven and a directly connected generator was driven at the same time.

[The problem that the idea aims to solve]

The above-mentioned independent generator system is noisy, requires a fuel tank and fuel pump for the prime mover, and takes up a large amount of space for the generator. Generators still have problems such as poor reliability and short lifespans when operated continuously for long periods of time and mounted on vehicles. Furthermore, the above-mentioned hydraulic power generation system has the problem that the power generation device is expensive and can only be used when the automobile engine has sufficient horsepower.

The present invention is an attempt to solve the above-mentioned problems. In other words, the present invention is quiet and does not produce noise unlike independent generator systems, requires less space, does not require unnecessary items such as a fuel tank, fuel pump, fuel filter, or fuel gauge, and is easy to maintain. The object of the present invention is to provide a mobile sales vehicle equipped with a rechargeable/dischargeable power supply device that is highly reliable, has a long service life, and is cheaper than a hydraulic power generation system.

[Means to solve the problem]

In order to achieve the above object, the mobile sales vehicle of the present invention includes a small generator driven by the car's main engine, a main battery that stores the electricity generated by the small generator, and an external battery. A charging device for charging the main battery from a power source, and an electric circuit wired to selectively feed power from the main battery and from an external power source to an in-vehicle device that consumes power. shall be held.

[Effect]

According to the present invention, when the on-vehicle equipment of a mobile sales vehicle operates, a large amount of current temporarily flows, but a small generator driven by the vehicle's main engine has enough power generation capacity to keep up with the current. If you do not have enough power to rely on it, you can replenish the power from the main battery that has been stored in advance, and in places where an external power source is available, use that external power source to charge the main battery. You can also do Also, when the vehicle is running and there is sufficient power generation capacity, the main battery is charged and ready for emergencies. Furthermore, after the daytime business ends, the main battery can be charged at night in preparation for the next day's business.

〔Example〕

As an example, a case where the present invention is applied to a so-called catering car equipped with a Greek-style hamburger cooking device will be described.

1 to 4 show the above-mentioned catering car, that is, the mobile sales vehicle, and FIGS. 5 to 8 show the flow of electricity in the mobile sales vehicle.

In FIGS. 1 to 4, 1 indicates a vehicle body, 2 indicates a driver's seat, and 3 indicates a passenger seat.

A partition 4 is provided at the rear of the driver's seat 2, a sliding door 5 is provided in the center, and a catering space 6 isolated from the driver's seat 2 is provided.

Inside the catering space 6, various cooking equipment and sanitary equipment are provided. For example, 7 is a hand washing sink for employees, 8 is a drawer on the top service table, and 9 is a cooking sink. 10 is the upper service table, and the lower part is the storage room 13 for LPG cylinders.
A door 11 is provided on the outside. Furthermore, a cupboard 12 is provided in the upper right corner to serve as a storage space for tableware, etc. Further, the lower space of the cooking sink 9 is used as a storage space for a fresh water supply pump 14, and the space in front of it is used as a fresh water tank 15.

In order to secure the necessary amount of fresh water tank required by regulations, a separate tank is installed.In relation to the balance of the car body and the center of gravity, as shown in Figure 3, the separate tank is located at the bottom of the left side of the car body. 16 were established.

On the other hand, on the left side of the catering space 6, an opening 17 is provided in the car body 1, and a reinforced glass 4
Install a sliding door. The left side of the catering space 6 is used as a direct sales outlet, so the entire surface is a service table, and behind the table is a Greek-style hamburger cooking device 18, and below it is a small on-board refrigerator 19 and a locker with shelves 20. establish.

Furthermore, lighting lights 21 and ventilation fans 22 are provided on the ceiling of the catering space 6.

Furthermore, a foldable tent device 23 and a speaker 24 are also installed on the left roof for commercial use.

Also, to collect waste water used for cooking and washing hands,
A sewage tank 25 with a required capacity is provided at the rear lower part of the vehicle body 1.

Naturally, these devices require the necessary clean water,
Sewage and gas piping has been installed, as well as electrical wiring.

Now, fresh water supply pump 1 that requires electricity.
4. There are a ventilation fan 22, a lighting lamp 21, and a refrigerator 19, but if all of these devices are 12 volts, the equipment may be arranged as shown in FIGS. 5 and 6.

That is, in FIGS. 5 to 8, electric power generated by a small generator 31 driven by a belt from a main driving engine 30 of an automobile is supplied to an automobile battery 32 and a separately provided large-capacity main battery 3.
Powered by 3. These batteries 32, 33
In this car, as shown in Figure 1,
It was stored in the front bonnet. Other external power supply
A battery charger 34 capable of receiving 100 volts, adjusting it to a predetermined voltage, and charging a main battery 33 is installed in front of the passenger seat 3. A connection port 35 for an external power source is provided on the front side wall.

When the catering car is driving the main motor vehicle engine 30, current flows as indicated by the arrow in FIG. The double arrow coming out of the car battery 32 indicates the flow of current to the car's original electrical equipment.

However, this catering car
When 0 is stopped, there is no charge from the small generator 31, so only the main battery 33 is discharged unilaterally. If this continues, the automobile battery 32 will also be discharged, and the main driving engine for the automobile will not start. Therefore, in order to prevent such a situation, a main battery 33 is provided separately for use in addition to the original automobile battery 32, and as shown in FIG. 6, the engine 30 is stopped. At this time, the configuration was such that no current flows from the automobile battery 32 to the main battery 33.

Furthermore, when an external power source (household 100 volt power source) is connected to the connection port 35 while the engine 30 is stopped, current flows and the main battery 33 is charged from the battery charger 34, as shown in FIG. Ru.

With this configuration, the in-vehicle device 1
Even if 9, 21, 22, and 14 require a temporary overcurrent when starting, the electric capacity stored in the main battery 33 is sufficient to cover it, so there is no need to modify the small generator 31 to a large and large capacity generator. Therefore, the original mechanisms of the automobile can be used in sufficient time.
However, the electrical energy consumed by the main battery 33 needs to be charged by an external power source while the vehicle is parked, such as at night.

The above is the in-vehicle equipment 19, 21, 22, 14.
All of these are for 12 volt specifications, but if these devices are 100 volt specifications, further ingenuity is required.

FIGS. 7 and 8 show the current flow in such a case.

In FIG. 7, the main engine 3 for driving an automobile
0. Although the small generator 31 and the automobile battery 32 are devices originally used in automobiles, an inverter 40 and a small generator 41 are also provided. This small-sized generator 41 may be replaced by the above-mentioned small-sized generator 31, but when the power consumption is large, the small-sized generator 31 cannot cover it, so a separate small-sized generator 41 is provided. However, this is on the condition that the engine 30 has surplus power.

Now, in the case of the configuration shown in FIG. 7, the current generated by the small generator 41 advances as shown by the arrow, and if there is a margin, part of it will be charged to the main battery 33, and the rest will be charged to the inverter 40. Therefore, the voltage is increased to 100 volts and the on-vehicle equipment 19, 21, 22,
14. At this time, if the power generation capacity is less than the power consumption, as described above, the main battery 33 is temporarily charged as shown by the double arrow to compensate for the shortage.

While the engine 30 is stopped, the automobile battery 32 and the main battery 33 are constantly being discharged, so if left as is, various devices will eventually stop working.

In order to prevent this from happening, FIG. 8 shows that when the engine 30 is stopped, the external power is connected to the vehicle equipment 19, 21, 2, as in the case of FIG. 6.
2 and 14, and also charges the main battery 33.

Now, the mobile sales vehicle configured in this way is loaded with sales equipment and can be freely visited at the sales location.

Since the purpose of this mobile sales vehicle is to cook and sell Greek-style hamburgers, it first stops at a crowded area and uses the car's driving engine 30.
is left in an idling state.

All the facilities necessary for cooking, such as water, gas, and electricity, are available, so you can cook immediately in the car, and when you are ready, unfold the tent of the tent device 23, open the glass door, and use the speaker 24. All you have to do is hang out and attract customers.

At the end of the business day, after returning home with the sales car in its original condition, the main engine 30 for driving the car is stopped, the external power source is connected, and the main battery 33 is left in that state until the next morning, and the main battery 33 is sufficiently charged. Prepare it the next morning.
