The transfer chain 131 is rotated by the driving force of the transfer motor 133, and the plurality of guide rollers 139 and the upper guide roller 138 are coupled to the inner side of the rack body 111 so as to be idlely rotated. When the transfer motor 133 is rotated, the transfer chain 131 is rotated between the guide roller 139 and the transfer gear 135. At this time, it is provided to rotate on the inner surface of the rack body 111 of the transfer chain (131). That is, the transfer chain 131 is provided to be rotated instead of reciprocating back and forth. The photovoltaic light shielding film 121 is moved along the transfer chain 131 toward the upper 131a side of the roof rack body 111 to cover the roof B of the vehicle A, and the roof rack along the transfer chain 131. It is moved to the lower side 131b side of the main body 111 and is stored in the accommodation space (M).

At this time, the side shading film 141 is provided in a shape with a small air resistance so as not to affect the running of the vehicle. To this end, it may be formed in a curved shape as shown.

When the area of the side awning film 141 is large, it is easy to block sunlight, but it is preferable to be provided with an appropriate area because it interferes with the running of the vehicle. The sunshade pivot shaft 143 is rotatably coupled to the outer surface of the rack body 111 and supports the side sunshade membrane 141. One end of the sunshade driving shaft 143 is coupled to the sunshade driving motor 145. The sunshade driving motor 145 is driven by receiving power from the storage battery 125. When the sunlight is strong, the sunshade driving motor 145 is rotated so that the side sunscreen 141 is moved downward as shown in FIG. 1, and when the sun is weak or rainy, the side as shown in FIG. 5. The sunshade driving motor 145 is reversely rotated such that the sunshade 141 rotates upward.

The sunshade driving motor 145 is operated by an input signal input by the driver through an input means such as a remote controller as described above. On the other hand, the side awning film 141 may be provided in plurality depending on the length of the rack body 111. That is, as shown in FIG. 2, two may be installed adjacent to each other along the longitudinal direction of the rack body 111. At this time, an electric gear 147 is provided between the adjacent sunshade driving shaft 143 to transmit the driving of the sunshade driving motor 145. Meanwhile, the roof rack assembly 100 of the present invention may be detachably coupled to the roof box 150 at the rear end of the rack body 111. The roof box 150 is coupled to the roof rack 110 when the vehicle lacks a loading space, and is separated from the roof rack 110 when it is not necessary to load the vehicle. The roof box 150 has a box body 151 in which load is accommodated therein, and a coupling arm 153 extending to a predetermined length on both sides of the box body 151 to be coupled to the coupling end 111a of the roof rack 110. It includes.

The box body 151 may be formed in the form of a bag formed of a fiber material, an enclosure formed of a metal material. The coupling arm 153 extends from the box body 151 toward the coupling end 111a of the rack body 111. The coupling arm 153 extends from both sides of the box body 151 and is disposed to overlap the outer surface of the coupling end 111a. The coupling member 157 is inserted through the coupling arm 153 and the coupling end 111a in a state where the coupling arm 153 overlaps the coupling end 111a so that the position of the roof box 150 and the roof rack 110 may be adjusted. It is fixed.

A process of using the roof rack assembly 100 according to the present invention having such a configuration will be described with reference to FIGS. 1 to 5. The driver installs the roof rack assembly 100 of the present invention on the top of his vehicle. For installation, select the roof rack assembly 100 suitable for your vehicle and purchase it. A pair of roof rack body 111 is arranged side by side on the roof (B) of the vehicle (A), and the fixing bracket 113 is coupled to both door coupling holes (C) of the vehicle (A). Insert the bent insertion end 113b of the fixing bracket 113 into the door coupling hole C, place the upper end of the vertical leg 113a at the end of the fixing bracket 113, and fix the fixing member 113c to the spanner. The roof rack body 111 is fixed to the roof B of the vehicle A by insertion using the same.

In the rear accommodating space M of the roof rack body 111, a photovoltaic light shielding film 121 is accommodated as shown in FIG. 3. In addition, a light shielding film transfer unit 130 for driving the photovoltaic light shielding film 121, a storage battery 125 storing electrical energy generated by photovoltaic power generation, and a control board 127 for controlling the same are accommodated. . At this time, the controller board 127 communicates with the ECU 170 of the vehicle and transmits and receives a control signal, and the storage battery 125 and the vehicle battery 160 may share power with each other. That is, when the power supply of the battery 125 is insufficient, the vehicle battery 160 may use power. When the power supply of the vehicle battery 160 is insufficient, the power supply of the battery 125 may be used in the vehicle A. The input unit 180 may be provided as 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 driver travels in a state in which the photovoltaic light shielding film 121 is accommodated in the accommodation space M, as shown in FIG. 3. In this state, the driver may load a baggage on the upper end of the roof rack 110 while the solar light shielding film 121 is accommodated in the accommodation space M. For example, in the winter, the ski equipment on the upper surface of the roof rack 110, or can be loaded leisure equipment.

However, when the amount of sunshine increases during the daytime, as shown in FIG. 4, the photovoltaic light shielding film 121 is spread over the roof B. FIG. When the use of the photovoltaic light shielding film 121 is input through the input unit 180, the controller board 127 supplies power of the storage battery 125 to the transfer motor 133. As the transfer motor 133 rotates, the transfer gear 135 rotates, and the transfer chain 131 circumscribed to the transfer gear 135 rotates. When the transfer chain 131 is rotated by the guides of the plurality of guide rollers 139, the photovoltaic light shielding film 121 coupled to the transfer chain 131 moves in front of the roof B and moves the roof B. It is covered.

As illustrated in FIG. 1, when the photovoltaic light shielding film 121 covers the entire roof B, the driving of the transfer motor 133 is stopped by a signal of a position sensor (not shown). The photovoltaic light shielding film 121 covers the entire roof B to block sunlight from directly contacting the roof B. As a result, the heat of solar light is blocked from being transferred to the inside of the vehicle, thereby increasing the cooling effect inside the vehicle. In this case, since the photovoltaic light shielding film 121 is disposed on the upper portion 131a of the transfer chain 131, the photovoltaic light shielding film 121 is spaced apart from the roof B of the vehicle A by a predetermined distance. The air is moved to the spaced space and the ventilation can be prevented from heating the roof (B) of the vehicle (A).

On the other hand, the solar light is absorbed to the surface of the photovoltaic light shielding film 121, the electrical energy is generated. Electrical energy is converted into AC power of a voltage that can be used in a vehicle in a converter (not shown) and then stored in the battery 125. The power stored in the battery 125 may be used to drive the transfer motor 133 or to drive the awning film driving motor 145 of the side awning module 140. In addition, when the power supply of the vehicle battery 160 is insufficient, the vehicle may be turned on or used to drive devices in the vehicle. In addition, when the outdoor activity, such as camping can be used to turn on the lighting using the power of the battery 125, use as an emergency power source of the remote area, or to supply the power of the camper. Since the power stored in the battery 125 is not a power generated by driving the engine of the vehicle A, there is an environmentally friendly advantage. At this time, the driver may drive the side awning module 140 to block the sunlight entering the glass window of the door. As shown in FIG. 5, the side awning film 141 which is normally rotated upward is rotated downward as shown in FIG. 1. When the use signal of the side awning module 140 is applied through the input unit 180, power of the storage battery 125 is supplied to the awning driving motor 145. As the awning film supply motor 145 rotates, the awning film rotating shaft 143 is rotated downward, and the side awning film 141 is rotated downward. This can reduce the amount of sunlight flowing through the glass window.

On the other hand, when the amount of sunshine is insufficient, such as evening time, as shown in Figure 3, the solar power shielding film 121 is moved back to the accommodation space (M). At this time, when the input signal is applied through the input unit 180, the transfer motor 133 is rotated in the reverse direction so that the photovoltaic light shielding film 121 is moved into the receiving space (M) along the transfer chain 131. At this time, according to the arrangement shape of the transfer gear 135 and the pair of guide gear 137, the photovoltaic light shielding film 121 is moved in a zigzag form and may be stored in the receiving space (M) without overlapping each other. . At this time, the side shading membrane module 140 may also rotate upward as shown in FIG. 5. On the other hand, when the driver has a lot of luggage to be loaded through the vehicle (A), the roof box 150 may be used in combination with the coupling end 111a of the roof rack 110. The driver arranges the coupling arm 153 of the roof box 150 to overlap the coupling end 111a of the roof rack 110, and fastens the fastening member 157 to move the roof box 150 to the upper portion of the vehicle A. Can be fixed at When the fixing is completed, the opening and closing door 155 of the box body 151 can be opened to load the luggage therein.

6 and 7 are perspective views illustrating the structure of the roof rack assembly 100a according to another embodiment of the present invention. In the roof rack assembly 100 according to the preferred embodiment of the present invention described above, the transfer chain 131 of the light shielding film transfer part is exposed to the outside in both the folded and unfolded state of the solar light shielding film 121. When the transfer chain 131 is exposed to the outside, air resistance is generated while the vehicle is running, thereby hindering the driving of the vehicle. Roof rack assembly 100a according to another embodiment of the present invention further includes a side cover 116 for concealing the transfer chain 131 in order to improve the obstruction to the running of the vehicle by the transfer chain (131).

Roof rack 110 according to another embodiment includes a secondary rack body 112 is spaced apart from the rack body 111 by a predetermined interval.

At this time, the control panel 127 communicates with the ECU 170 of the freight vehicle and transmits and receives a control signal, and the storage battery 125 and the vehicle battery 160 may share power with each other. That is, when the power supply of the battery 125 is insufficient, the vehicle battery 160 may use power, and when the power supply of the vehicle battery 160 is insufficient, the power of the battery 125 may be used in the freight vehicle A. The input unit 180 may be provided as a remote controller or may be coupled to one side of the roof rack 110. When the driver is driving the freight vehicle A and the sunlight is not strong, the driver travels in a state where the photovoltaic light shielding film 121 is accommodated in the accommodation space M, as shown in FIG. 11. At this time, the front end 121a of the photovoltaic light shielding film 121 is maintained in a state where the rear end of the pair of roof racks 110 is completely moved, and the remaining area of the photovoltaic light shielding film 121 is the coupling box 150. ) It is stored inside. At this time, since the side cover 116 covers the upper part of the roof rack body 111 and the auxiliary rack body 112 as shown in an enlarged view in FIG. 11, the transfer chain 131 is not exposed to the outside. As a result, it is possible to prevent the transfer chain 131 from generating resistance when the freight vehicle A runs. When the amount of sunshine increases during the day, the controller board 127 supplies power of the storage battery 125 to the transfer motor 133 by an input signal from the driver. In addition, the controller board 127 drives the lifting shaft lifting means (not shown) of the side cover 116 to raise the lifting shaft 116b as shown in FIG. 12.

The photovoltaic light shielding film 121 covers the entire coupling box 150 to block the solar light from directly contacting the roof (B). That is, the inflow of sunlight is primarily blocked by the coupling box 150, and the inflow of sunlight is secondarily blocked by the photovoltaic light shielding film 121. As a result, the heat of sunlight is blocked from being transferred to the inside of the freight vehicle, thereby increasing the cooling effect inside the freight vehicle. On the other hand, the solar light is absorbed to the surface of the photovoltaic light shielding film 121, the electrical energy is generated. Electrical energy is converted into AC power of a voltage that can be used in a freight vehicle in a converter (not shown) and then stored in the storage battery 125. The power stored in the battery 125 may be used to drive the transfer motor 133 or to drive the awning film driving motor 145 of the side awning module 140. In addition, when the power supply of the vehicle battery 160 is insufficient, it may be used to turn on the start of the freight vehicle or to drive the devices inside the freight vehicle. At this time, the driver may drive the side awning module 140 to block the sunlight entering the glass window of the door. As shown in FIG. 11, the side awning film 141 which is rotated downward is normally rotated upward as shown in FIG. 13. When the use signal of the side awning module 140 is applied through the input unit 180, power of the storage battery 125 is supplied to the awning driving motor 145. As the awning film supply motor 145 rotates, the awning film rotating shaft 143 is rotated upward, and the side awning film 141 is rotated upward. This can reduce the amount of sunlight flowing through the glass window. On the other hand, when the amount of sunshine is insufficient, such as evening time, as shown in FIG. 11, the photovoltaic light shielding film 121 is moved to the coupling box 150 again. At this time, when the input signal is applied through the input unit 180, the transfer motor 133 is rotated in the reverse direction, the solar light shielding film 121 is moved to the coupling box 150 along the transfer chain 131. At this time, the side shading membrane module 140 may also rotate in a downward direction as shown in FIG. 11.

The present invention can be used in the automobile manufacturing industry.
