Abstract

A device is formed by mounting a generator 5 capable of generating power, used for welding, lighting and power tool, in a lower part of a loading space 2 in a vehicle 1, further by integrally mounting a step-up gear 3 in one side of the generator 5 and a distribution panel 4 in the other side of the generator 5, and further by connecting a side PTO, mounted on a transmission, and the step-up gear 3 by a propeller shaft.

Description

Electric source equipment installed under cabin of car

The present invention relates to be installed on and be provided with side PTO(Partial Transmission Outlet) the supply unit of lorry compartment bottom.

In the vehicle of routine, be provided with to drive a vehicle needed specific 12V or the generator of 24V.

Owing to the generator that is arranged in the conventional vehicles is established for driving, carry out in the field that does not have power supply in the field operations such as sheet metal brandreth, certainly can not utilize, at the scene when the operation, must on lorry compartment, load the required distribution board of field operation, generator, therefore need another for loading the vehicle of field operation equipment needed thereby, have very problems such as labor intensive, fund, man-hour.

The present invention's purpose is, on a lorry compartment, load devices such as distribution board, generator and use the All Jobs of power supply in power free field, the illumination operation of for example sheet metal operation, brandreth operation and building or construction site need not another truck and loads field operation equipment needed thereby or extensively effectively utilize the space, compartment under the roomy situation of lorry compartment.

For achieving the above object, in being provided with the vehicle of side PTO of the present invention, install in the bottom, compartment can send be used to weld, the generator of the electric power of illumination and electric tool etc., and the end at said generator is installed booster engine, at the relative therewith other end distribution board and said generator are installed together, the side PTO and the said booster engine that will be installed on the gearbox are connected on the power transmission shaft again.

In addition, be provided with three kinds of plugs, and be provided with (capacity) adjusting knob of scalable electric current for one of them welding plug at above-mentioned distribution board.

Be installed in the driving that side PTO on the gearbox accepts engine, accepted by power transmission shaft again by the motor driven that this side PTO accepts, accepted by booster engine again by the motor driven that this power transmission shaft receives, accepted by generator again by the motor driven after this booster engine speedup.

Accepted by distribution board by the electricity that this generator sent, obtain required electric energy, can carry out power free field work, for example sheet metal operation and brandreth operation etc. by this distribution board.

The driving that (under the neutral state) accepted engine when side PTO stopped at vehicle plays a role.

Booster engine makes the motor driven speedup, accelerates the rotation of generator, plays the effect that improves power.Thereby reduced the rotation of engine, made the sound peace and quiet, played preventing the noise that causes by engine sound.

This booster engine can send said generator to be used for welding (about 5.4KW), throw light on (about 3KW) and the big electric energy of electric tool (about 3KW).

And the 50Hz/60Hz illumination of power supply, 100V that is provided with the usefulness such as 50Hz/60Hz electric tool of 200V on the distribution board of accepting by the electric power that said generator sent is with three kinds of plugs of the power supply of, power supply such as home-use and welding usefulness, thereby can select and the corresponding power supply of operation, and, then can regulate the size of electric current for the plug of welding usefulness is provided with (capacity) adjusting knob.

Fig. 1 is the figure that expression is installed in supply unit of the present invention the lorry compartment bottom.

Fig. 2 is the figure of expression supply unit embodiment of the present invention.

Embodiment 1

Embodiments of the invention are described with reference to the accompanying drawings.

In Fig. 1, express the truck vehicle thatbooster engine 3,generator 5 anddistribution board 4 have been installed.

Booster engine 3,generator 5 anddistribution board 4 are installed in the bottom in truck 1compartment 2, with bolt framework are arranged on the chassis ofgearbox 13 of truck 1, and saidbooster engine 3,generator 5 anddistribution board 4 are set on this frame-saw frame.

As shown in Figure 2, installation side PTO12 ongearbox 13.

In vehicle stops, be that clutch 1 is when being in the neutral state, side PTO12 accepts the driving according to theengine 10 of thegenerator 9 that is used to make truck 1 to travel, be in when sailing state at truck, side PTO does not accept the driving ofengine 10, and the driving ofengine 10 in such cases becomes and is used to make tire rotatingdrive shafts 15 to accept.

Side PTO12 is connected withbooster engine 3 withpower transmission shaft 14, and the driving of the engine of being accepted by said PTO12 10 is accepted bygenerator 5 again.

In the case, accepted bygenerator 5 by the driving of theengine 10 afterbooster engine 3 speedups, thereby can send high electric energy,, and prevented noise because of the peace and quiet of engine sound.

Like this,generator 5 can send high electric energy, thereby can send the electric energy that can be used for welding (about 5.4KW), illumination (about 3KW) and electric tool (about 3KW) etc.

Withcable distribution board 4 is connected withgenerator 5, assemble in aggregates, the illumination of 50Hz/60Hz that is provided with electrical source of power that the electric tool of the 50Hz/60Hz of 200V uses, 100V on distribution board is with three kinds of plugs 6,7,8 of, home-use power supply and the power supply that is used to weld, and regulates (capacity) adjusting knob that electric current is used for the plug 8 of welding usefulness is provided with.

In these three kinds of plugs 6,7,8, can select the power supply corresponding with corresponding operation, and the size that can regulate electric current according to (capacity) adjustingknob 16.

Because the present invention has formation as mentioned above, produced following effect.

In power free field, utilize the present invention, can carry out can carrying out in addition in night work, using all operations of mains lighting supply with operations such as welding, the sheet metal of bore operation and brandreths, reduce labor intensity seeking.

Because need not, with regard to loading these devices, also will not to be loaded on other vehicle by the required equipment of field operation at the supply units such as generator of vehicle loading as power supply, then can seek to alleviate labour, cost reduction, save time.

In the roomy situation of vehicle car, can effectively utilize the space, compartment in addition.

And the present invention is installed in the situation on the place car of camping, can be used for camping the television set of place car, the power supply of freezer.
