(12) The guide 30 is mounted to a rear floor 1, a back panel 3, and a back beam 4. The in-wheel motor roller and the slider are operated along the guide 30 to load or unload luggage which is placed on the plate 50 coupled to the slider.

(13) The in-wheel motor roller is rotatably coupled to a roller coupling end portion 10 of the link 40, and a wheel built therein rolls and rotates by the driving force of a motor.

(14) The in-wheel motor roller and the slider are interconnected by the link 40 such that the slider may be operated depending on the operation of the in-wheel motor roller.

(15) The slider is coupled to a slider coupling end portion 20 of the link 40, and the plate 50 is coupled to the slider so that the position of the plate 50 is changed along with the slider.

(16) As illustrated in the drawings, since the link 40 has a longitudinally curved shape, the link 40 may not conflict with the trunk and the guide 30 and the slider may be guided along the guide 30.

(17) The luggage loading and unloading apparatus having such a structure not be heavily exposed in external appearance in the vehicle to apply the apparatus to the typical commercial vehicle. In addition, it is necessary to safely mount the apparatus to the vehicle for transportation of heavy luggage.

(18) To this end, the guide 30 has one opened surface and three closed surfaces on the basis of the rear of the vehicle, and includes a floor seating portion 31, a board horizontal portion 32, a panel coupling portion 33, an inclined portion 34, and a beam coupling portion 35.

(19) The floor seating portion 31 is a portion which is smoothly mounted to the rear floor 1 such that the link 40 and the plate 50 may be disposed on the rear floor 1 without exposure to the outside and may be covered by a luggage board 2 when the apparatus does not transport luggage.

(20) The board horizontal portion 32 is a portion which is smoothly mounted on the lower surface of the luggage board 2 to position the guide 30 such that the plate 50 may be seated on the luggage board 2 after reaching the highest position.

(21) The panel coupling portion 33 is a portion which is mounted to the back panel 3 of the vehicle such that the guide 30 bent toward the rear end portion thereof from the board horizontal portion 32 is securely mounted to the vehicle and is not exposed in external appearance. The plate 50 is located at the highest position when it reaches the panel coupling portion 33.

(22) The beam coupling portion 35 is a portion corresponding to the rearmost end portion of the guide 30, and is vertically formed such that luggage may be loaded or unloaded when the plate 50 is located at the beam coupling portion 35. The beam coupling portion 35 is mounted to the back beam of the vehicle such that the guide 30 is securely mounted to the vehicle and is not exposed in external appearance.

(23) The inclined portion 34 between the panel coupling portion 33 and the beam coupling portion 35 forms an angle of inclination when viewed from the side.

(24) For the configuration of the guide 30 as described above, the luggage board 2 and a bumper cover disposed in the rearmost end portion of the vehicle are partially cut such that the link 40 and the plate 50 may be exposed for transportation.

(25) As illustrated in FIG. 3, the slider has a triangular shape to be suited for the movement of the slider and the plate 50. That is, the triangular slider is more advantageous to horizontally maintain the lifting and dropping plate 50.

(26) To this end, the link 40 is preferably coupled to one edge portion of the triangular slider. The upper edge portion in the drawing is an edge portion coupled to the link 40.

(27) As illustrated in the drawing, the slider having a triangular shape in section is safely movable by seating the short side of the slider on the guide when the slider is located at the beam coupling portion 35 and the panel coupling portion 33. When the slider moves along the inclined portion 34, the slider may horizontally transport the plate 50 in the state in which the edge portion of the slider, the internal angle of which is a right angle, is in contact with the inside of the guide 30 and the slider maintains its center of gravity.

(28) To this end, the side of the inclined portion 34 is preferably alongside of the long side of the slider, as illustrated in the drawing.

(29) The operation of the luggage loading and unloading apparatus for a vehicle having the above-mentioned structure according to the exemplary embodiment of the present invention will be described with reference to FIG. 4, FIG. 5, FIG. 6, and FIG. 7.

(30) As illustrated in FIG. 4, when the slider and the plate 50 are coupled to the beam coupling portion 35 of the guide 30 and are located at the lowest position, luggage is loaded on or unloaded from the plate 50.

(31) In the instant case, the link 40 is exposed to the outside of the trunk, and the roller coupling end portion 10 is substantially located at the panel coupling portion 33.

(32) In this state, when the in-wheel motor roller is operated along the guide 30 in the forward direction of the vehicle by the driving of the motor, the link 40, and the slider and the plate 50 connected thereto are moved forward of the vehicle together. Consequently, the plate 50 is moved upward as illustrated in FIG. 5.

(33) The curved link 40 is in a state illustrated in FIG. 5. To this end, a portion of the luggage board 2 is partially open to the link side.

(34) When the in-wheel motor roller is further moved, the plate 50 is located at the highest position as illustrated in FIG. 6. In the instant case, the plate 50 is located on the panel coupling portion 33 of the guide 30.

(35) Next, as illustrated in FIG. 7, the link 40 is moved downward of the luggage board 2 so as not to be exposed in external appearance, and is located in the space between the luggage board 2 and the rear floor 1.

(36) The plate 50 is seated on and supported by the luggage board 2, and thus the movement of luggage into the trunk is completed.

(37) The process of unloading the luggage may be performed by operating the apparatus in reverse order.

(38) As described above, the luggage loading and unloading apparatus for a vehicle according to the exemplary embodiment of the present invention includes the guide which is securely and properly disposed therein for stable transportation of luggage, and is embodied on the guide by the simple structure of the in-wheel motor roller and the link. Thus, the luggage loading and unloading apparatus can be minimally exposed in external appearance in the vehicle, and a vehicle user can easily load and unload luggage into and from the trunk by properly transporting the luggage on the plate.

(39) In accordance with a luggage loading and unloading apparatus for a vehicle according to exemplary embodiments of the present invention, it is possible to easily load and unload luggage using a relatively simple and cheap device, compared to large and expensive devices including six-joint links applied to welfare vehicles.

(40) Since the luggage loading and unloading apparatus has a proper height to load and unload luggage on and from a luggage plate, it does not impose a burden on the human body.

(41) The luggage loading and unloading apparatus can have a suitable layout to be hardly exposed through a vehicle trunk, and thus can be easily applied to typical mass-produced vehicles.
