In the meantime, the roof rack assembly 100 of the present invention can be detachably coupled to the rear end of the rack main body 111. The roof box 150 is used in combination with the roof rack 110 when there is a lack of space in the vehicle, and is separated from the roof rack 110 when there is no need to load.

The loop box 150 includes a box body 151 in which a bag is accommodated, a coupling arm 153 formed to extend to a predetermined length on both sides of the box body 151 and coupled to the coupling end 111a of the roof rack 110, .

The box body 151 may be formed in the form of a bag formed of a fiber material or a metal body. The coupling arm 153 extends from the box body 151 toward the coupling end 111a of the rack body 111. [ The coupling arms 153 extend from both side surfaces of the box body 151 and are disposed to overlap the outer surface of the coupling end 111a. The coupling member 153 is inserted through the coupling arm 153 and the coupling end 111a in a state where the coupling arm 153 is overlapped with the coupling end 111a so that the positions of the roof box 150 and the roof rack 110 are .

The use of the roof rack assembly 100 according to the present invention having such a configuration will be described with reference to Figs. 1 to 5. Fig.

The driver installs the roof rack assembly 100 of the present invention on the upper portion of his / her own vehicle. For the installation, the roof rack assembly 100 is selected and purchased according to the vehicle type. A pair of roof rack bodies 111 are arranged side by side on the roof B of the vehicle A and the fixing brackets 113 are coupled to both door fittings C of the vehicle A. [ The bending insertion end 113b of the fixing bracket 113 is inserted into the door coupling hole C and the upper end of the vertical leg 113a is disposed at the end of the fixing bracket 113 and the fixing member 113c is inserted into the hole So that the roof rack body 111 is fixed to the roof B of the vehicle A.

3, a solar photovoltaic light-shielding film 121 is accommodated in the space M accommodated in the rear end of the roof rack body 111. [ A shielding film transferring part 130 for driving the photovoltaic power generating shielding film 121, a storage battery 125 storing electric energy generated by the solar power generation, and a control board 127 for controlling the same are accommodated .

At this time, the control board 127 communicates with the ECU 170 of the vehicle and transmits and receives a control signal, and the battery 125 and the vehicle battery 160 share power. That is, the power source of the vehicle battery 160 can be used when the power source of the battery 125 is insufficient, and the power source of the battery 125 can be used in the vehicle A when the power source of the vehicle battery 160 is insufficient.

The input unit 180 may be provided with a remote controller or may be coupled to one side of the roof rack 110. When the driver is driving the vehicle A and the sunlight is not strong, the photovoltaic light shielding film 121 travels in a state accommodated in the accommodation space M as shown in FIG.

In this state, the driver can load the load on the top of the roof rack 110 while the photovoltaic shading film 121 is accommodated in the accommodation space M. For example, ski equipment can be loaded on the upper surface of the roof rack 110 in winter, or leisure equipment can be loaded.

However, when the amount of sunshine increases in the daytime, the photovoltaic power generation shielding film 121 is spread on the roof B as shown in FIG. When the use of the photovoltaic power generation shielding film 121 is input through the input unit 180, the control board 127 supplies power of the storage battery 125 to the feed motor 133.

The feed motor 135 rotates and the feed gear 135 rotates and the feed chain 131 circumscribed to the feed gear 135 rotates. When the conveying chain 131 is rotated by the guide rollers 139, the photovoltaic light shielding film 121 coupled to the conveying chain 131 moves to the front of the roof B, Lt; / RTI >

When the photovoltaic light shielding film 121 covers the entire roof B as shown in Fig. 1, the driving of the feed motor 133 is stopped by a signal from a position sensor (not shown). The photovoltaic power generation shielding film 121 covers the whole roof B to block direct sunlight from coming into contact with the roof B. [ As a result, the heat of the sunlight is prevented from being transmitted to the interior of the vehicle, thereby enhancing the cooling effect inside the vehicle.

At this time, the solar light shielding film 121 is disposed on the upper portion 131a of the transfer chain 131, and is spaced apart from the roof B of the vehicle A by a certain distance. It is possible to prevent the roof B of the vehicle A from becoming hot.

On the other hand, solar energy is absorbed into the surface of the solar photovoltaic light-shielding film 121 and electrical energy is generated. The electric energy is converted into AC power at a voltage that can be used in the vehicle in a converter (not shown) and then stored in the battery 125.

The power stored in the battery 125 can be used to drive the feed motor 133 or to drive the winging membrane drive motor 145 of the side wing module 140. [ Further, when the power of the vehicle battery 160 is insufficient, the vehicle can be turned on or can be used to drive internal equipments.

In addition, when outdoor activities such as camping are performed, the battery 125 can be used to turn on the lights, to use as an emergency power source for the outdoors, or to supply power to the camper. Since the power stored in the storage battery 125 is not a power generated by driving the engine of the vehicle A, there is an advantage of being environmentally friendly.

At this time, the driver can drive the side sunshield module 140 to block the sunlight coming into the window of the door. As shown in FIG. 5, the side sunshield 141, which is normally rotated upward, is rotated downward as shown in FIG. When the use signal of the side window module 140 is applied through the input unit 180, the power of the battery 125 is supplied to the wing-film drive motor 145. The shade film rotating shaft 143 is rotated in the downward direction while the shade film supply motor 145 is rotated, and the side shade film 141 is rotated downward. Thereby reducing the amount of sunlight flowing through the windshield.

On the other hand, as shown in FIG. 3, the photovoltaic power generation shielding film 121 is moved back to the accommodation space M during a time period when the amount of sunshine is insufficient as in the evening. At this time, when an input signal is applied through the input unit 180, the feed motor 133 rotates in the reverse direction, and the solar light generation shielding film 121 is moved into the accommodation space M along the transfer chain 131. The solar light shielding film 121 may be moved in a zigzag manner depending on the arrangement of the feed gear 135 and the pair of guide gears 137 and may be stored in the accommodating space M without being overlapped with each other .

At this time, the side sunshield module 140 can also be rotated upward as shown in FIG.

On the other hand, if there are many loads to be loaded by the driver through the vehicle A, the roof box 150 can be coupled to the coupling end 111a of the roof rack 110 and used. The driver places the coupling box 153 of the roof box 150 on the coupling end 111a of the roof rack 110 and tightens the coupling member 157 to connect the roof box 150 to the upper portion of the vehicle A As shown in Fig.

When the fixing is completed, the opening / closing door 155 of the box body 151 can be opened to load the load.

8 is an exemplary view showing a configuration of the roof rack assembly 100b according to still another embodiment.

The roof rack assemblies 100 and 100a described above are provided on the roof of the passenger vehicle. That is, since the roof rack 110 is installed only on the roof of the passenger vehicle, the solar light shielding film 121 can cover only the roof, and the space outside the roof, that is, the area connecting the trunk and the roof with the roof, .

Accordingly, the roof rack assembly 100b according to another embodiment is formed such that the roof rack 110a extends from the roof of the vehicle to the inside of the trunk. At this time, the trunk lid M of the passenger vehicle is rotated in the opposite direction and opened and closed unlike a general passenger vehicle.

A conveying motor 133 is provided inside the trunk, and a folded solar cell light-shielding film 121 is accommodated in the trunk. When the photovoltaic power generation shielding film 121 is spread by the user's input signal, the photovoltaic power generation shielding film 121 covers the entire roof of the vehicle from the trunk.

As a result, the area in which direct sunlight enters into the vehicle is reduced, cooling efficiency can be improved, and the photovoltaic generation area can be widened, thereby increasing the efficiency of photovoltaic power generation.

Meanwhile, in the roof rack assembly 100 according to the preferred embodiment of the present invention, the battery 125 of the photovoltaic module 120 may be accommodated separately in the trunk of the vehicle as the case may be. In this case, the power generation board 127 can be electrically connected to the electric wire. When the battery 125 is relatively large in size and positioned between the top cover 117 and the rear cover 118, the battery 125 may interfere with the movement of the photovoltaic light shielding film 121 and may be separately stored in the trunk.

As described above, the roof rack assembly according to the present invention can be used for transporting solar photovoltaic light shielding films in addition to a roof rack loading. Solar photovoltaic panels are spread on the roof of the vehicle, preventing direct sunlight from entering the interior of the vehicle. As a result, an increase in the room temperature inside the vehicle is partially reduced, so that the fuel and electricity consumption of the vehicle can be reduced.

In addition, the photovoltaic solar light shield film absorbs solar light in the state of being spread on the roof of the vehicle, and generates electric energy. The generated electric energy can be stored in a battery and used for transferring a photovoltaic shading film or can be used for driving internal devices of a vehicle. It can also be used as an emergency power source for outdoor activities.

Further, the roof rack assembly according to the present invention is provided with the side sunshield module on the side of the roof rack. The side sunshield module is rotatably mounted on both sides of the roof rack to minimize the amount of sunlight entering the windshield of the vehicle. Accordingly, it is possible to reduce the amount of sunlight flowing into the interior of the vehicle together with the solar light generation shielding film, thereby allowing internal drivers to relax more comfortably and to increase cooling efficiency.

In addition, the roof rack assembly according to the present invention can be easily combined with the roof box to load a large amount of load.
