It is provided fixed on the other side of the fixing band 710 is configured to include a hook (720) on which the hook (711) is hooked.

That is, in a state in which the support member 450 is folded on the lifting plate 440, one end is pulled on the fixing band 710 having the shaft fixed, and the hook 711 provided at the other end is hung on the clamp 720, so that the lifting plate ( The support member 450 is fixed to the 440 to maintain the folded state.

Hereinafter, a method of using the vehicle interior mounted power lift configured as described above will be described.

First, when unloading the cargo in the loading box 11, open both the opening and closing doors 100a and 100b as shown in FIG. 3, and then, as shown in FIG. 4A, the fixing pipe of the support member 500 provided in the opening and closing door 100a. The lifting pipe 520 drawn into the 510 is drawn out, and the adhesion plate 521 formed at the lower end of the lifting pipe 520 is brought into close contact with the floor, and then the lifting pipe 520 is fixed using a fixing bolt 530 . It is fixed to the pipe (510). At this time, the pad part 540 is provided at the lower end of the contact plate 521 so that the lifting pipe 520 can be stably maintained on the floor even on an uneven floor. Accordingly, the opening and closing door 100a is provided in a state supported on the floor by the support member 500 .

Thereafter, as shown in FIGS. 4B and 4C, the support member 450 folded on the lifting plate 440 is unfolded, and then the folded first support plate 450-1 and the second support plate 450-2 are unfolded and unfolded. After loading the cargo on the upper portions of the first support plate 450-1 and the second support plate 450-2, the control device 433 of the actuator part 430 is operated to withdraw from the cylinder part 431 as shown in FIG. 4D. As the conveying rod 432 is drawn into the inside of the cylinder part 431 and the elevator 420 is lowered, the elevator plate 440 is moved downward to unload the cargo.

Conversely, if you want to load the cargo into the loading box 11, after placing the cargo on the top of the first support plate 450-1 and the second support plate 450-2 in the state of FIG. 4d, the actuator unit 430. of the control device 433 to draw out the transfer rod 432 inserted into the cylinder part 431 to raise and lower the elevator 420, the elevator plate 440 is moved upward to load the cargo.

And when not in use after loading or unloading the cargo as described above, the unfolded first support plate 450-1 and the second support plate 450-2 are stacked and folded, and then the first support plate 450-1 is folded again. It is folded on the lifting plate 440 . At this time, it is preferable that the lifting plate 440 is located at the upper part in a state in which the transfer rod 432 is drawn out to the cylinder part 431 .

Thereafter, in a state in which the support member 450 is folded on the lifting plate 440 , as shown in FIG. 3 , the outside of the support member 450 is wrapped with a fixing band 710 which is a fixing means 700 provided in the opening and closing door 100a. By hooking the hook 711 provided at the other end of the fixing band 710 to the hook 720 in the state, the support member 450 is fixed in the folded state, and then the opened and closed doors 100a and 100b are closed and loaded ( 11), the work is completed by sealing the open rear end.

That is, according to the present invention, heavy cargo can be easily and safely loaded on or off the loading box 11 , and when not in use, the vehicle interior-mounted power lift 10 is installed inside the loading box 11 as shown in FIG. 5 . By allowing it to be accommodated, it is possible to prevent corrosion by rain or snow or to be damaged by external impact in advance.
