BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device for a roof carrier for a vehicle and a roof carrier using the same. More specifically, in the case of a multipurpose and multifunctional vehicle such as a recreational vehicle or a sports utility vehicle, It is very inconvenient to load the goods in the roof carrier on the roof of the vehicle because it is higher than the general passenger car, and there is a concern about the damage of the goods and the risk of the physical risk of the loader. Therefore, the roof carrier is automatically loaded when the goods are unloaded. To move the vehicle to the rear of the vehicle and automatically lower and lower the carrier body to a lower position than the roof of a multi-purpose vehicle such as RV (recreational vehicles) or sports utility vehicles (SUV). At the same time, the vehicle is mounted on the roof carrier even when the vehicle is traveling at a high speed, at a sudden stop, or at a sudden start. The product relates to a load carrier using prevented the risk of falling to the outside, and the lifting device for a vehicle, which load carrier article of a large load could not be loaded in the conventional load carrier can also be put down without load and it.

In general, the conventional roof carrier is a fixed type mounted on the roof of the vehicle so that ski equipment or other items can be loaded, such as RV (recreational vehicles) or sports utility vehicles (SUV) In the case of high, there were many inconveniences and difficulties in loading the article into the roof carrier.

In addition, when the load of the load article is large, a person must lift and load the article directly on the roof carrier, and there is a closed end in which the actual load of the article cannot be loaded on the roof carrier.

In order to overcome such problems, various technologies such as Korean Utility Model Publication No. 20-0313015, Korean Patent Registration No. 10-0150404, Korean Patent Publication No. 10-0432077, and Korean Patent Application Publication No. 10-2004-0050207 Although it has been proposed, the slide-link device of the Korean Utility Model Publication No. 20-0313015 and the loop carrier using the same are used to lift the carrier in the vehicle width direction by using the link device, but the lifting motion is not automatic, but the manual movement of the person. It is made by manipulation and still has some inconveniences.

On the other hand, the electric carrier installed in the roof of the vehicle of the Korean Patent Publication No. 10-0150404 automatically operates the lifting movement by the driving of the motor, but the rail on the roof extends to the rear glass of the vehicle, which is very good in appearance. In addition, there is no risk of falling of the loaded goods because there is no separate means for fixing the carrier during a sudden stop or start of the vehicle, and there is still the inconvenience of having to lift a heavy load over the waist and rotation to support the carrier. There is also a risk of damaging the roof of the vehicle when loading a heavy article in the presence of the wheels.

In addition, although the roof rack of the automobile of Publication No. 10-0432077 is configured to adjust the interval of the roof rack according to the state or size of the loaded goods, the carrier is also fixed on the roof of the vehicle when loading or unloading heavy goods It still has the above problem.

As shown in FIG. 3, the lower sliding member 170 having the above structure has a predetermined length toward the rear of the vehicle along the lower guide rail 150 by driving of the lower driving motor 370, that is, forward rotation driving. As the sliding movement is performed, the upper guide rail 190 including the carrier body 230 and the upper sliding member 210 is integrally moved to the rear of the vehicle. On the contrary, when the lower driving motor 370 is driven in reverse rotation, the lower sliding member 170 is inserted into the lower guide rail 150 again.

On the other hand, Figure 4 is an upper drive motor to the second rack 250b of the upper sliding member 210 and the third rack 250c of the carrier body 230 of the lifting device 100 of the vehicle roof carrier according to the present invention. A bottom view schematically showing a state in which the upper pinion 430 and the carrier pinion 450 of 390 are engaged with each other. Specifically, FIG. 4C is a bottom view showing a state before the operation, and FIG. After the operation, in particular, the bottom view showing a state after the forward rotation drive occurs, E of Figure 4 is a bottom view showing a state in which the carrier pinion 450 is separated from the third rack 250c of the carrier body 230, 4F is a bottom view showing a state in which the operation is completed.

More specifically, before the upper driving motor 390 is driven, the upper sliding member 210 and the carrier body 230 are inserted into the upper guide rail 190. Here, the upper guide rail 190 has a second through hole 270b formed at an inner side and an outer side thereof so that both shafts 470 of the upper driving motor 390 can be inserted, and the upper side has the upper side. The second pinion 290b is formed to the upper pinion 430 of the drive motor 390 and the second rack 250b formed in the center portion of the bottom surface of the upper sliding member 210, the lower surface Is coupled to one end of the upper and lower connection member 490 is configured to hinge the lower sliding member 170.

In addition, the upper sliding member 210 is inserted in the upper portion of the upper guide rail 190 to perform a sliding movement in a longitudinal direction of the vehicle by the driving of the upper driving motor 390. In addition, the carrier body 230 as well as the upper sliding member 210 by the driving of the upper drive motor 390 performs a sliding movement by a predetermined length in the longitudinal direction of the vehicle.

In addition, the installation position and the installation length of the second rack 250b of the upper sliding member 210 and the third rack 250c of the carrier body 230 are as shown in FIG. 4, the second rack 250b. In the case of the bottom portion of the upper sliding member 210, that is, formed in a predetermined length on the lower surface center portion is configured to be engaged with the upper pinion 430 of the upper driving motor 390, the third rack 250c In the case of the carrier body 230 is formed to a certain length on the outer side of the bottom surface is configured to engage with the carrier pinion 450 of the upper drive motor 390.

Here, the length of the second rack 250b is preferably formed to the length of the body of the upper sliding member 210 as shown in FIG. This is because the longer the length of the second rack 250b is, the carrier body 230 can be lowered closer to the ground when the article is loaded. In addition, the length of the third rack 250c is preferably formed on the entire outer surface of the bottom of the carrier body 230 as shown in FIG. The reason for forming the length of the third rack 250c in the entire body of the carrier body 230 is that the carrier pinion 450 is driven when the upper drive motor 390 is driven, that is, the forward rotation drive. This is to allow the third rack 250c to be separated. (See E of FIG. 4.) When the carrier pinion 450 does not leave the third rack 250c, the carrier body 230 This is because the carrier body 230 can not be lowered closer to the ground when the article is loaded because the sliding movement cannot be performed to the outside of the upper sliding member 210.

 However, the installation position and the installation length of the second rack 250b and the third rack 250c take into consideration the installation position of the cylinder 510 to the installation position of the upper driving motor 390 and the load of goods to be loaded. The upper sliding member 210 and the carrier body 230 is preferably configured as an arm rack to enable a smooth sliding movement on the upper guide rail 190 and the upper sliding member 210. Do.

Here, the upper drive motor 390 is preferably composed of a bi-directional drive motor capable of forward and reverse rotation, more preferably the shaft 470 of the lower drive motor 370 is formed on both sides of the driving force More preferably, it is composed of a biaxial drive motor that can deliver. In addition, the upper pinion 430 meshes with the second rack 250b and the carrier pinion 450 meshes with the third rack 250c on a part of both shafts 470, that is, both ends of both shafts 470. Each of which is provided, the radius of the carrier pinion 450 is preferably configured to be at least twice the radius of the upper pinion 430.

Configuring the radius of the carrier pinion 450 to at least two times the radius of the upper pinion 430 is as shown in the bottom view of the operating state of FIG. 4, when the upper driving motor 390 is driven. While the upper sliding member 210 performs the sliding movement by a predetermined length by the rotational force of the upper pinion 430, the carrier body 230 of the upper sliding member 210 by the rotational force of the carrier pinion 450 This is to secure the sliding length more than twice the sliding length. In this way, at least two times the sliding length must be secured so that the carrier body 230 can be lowered close to the ground. In the case where the radius of the carrier pinion 450 is further increased, it can be seen that the carrier body 230 is lowered closer to the ground as described above, so that the loading and unloading of the article is convenient. However, when the radius of the carrier pinion 450 is too large, the volume of the lifting device 100 of the present vehicle roof carrier and the roof carrier 700 using the same increase, so that the radius of the upper pinion 430 is 2.5. Most preferably, it is composed of 3 to 3 times.

5A and 5B are perspective views schematically showing an upper sliding member 210 including a stopper 330 and a carrier body 230 including a latch 350, specifically, the carrier body 230. When the carrier pinion 450 is separated from the third rack 250c, the carrier body 230 no longer slides at the predetermined position on the guide rail 650 of the upper sliding member 210. It is provided with a stopper 330 that can stop the carrier body 230, the stopper 330 is provided in the rear portion on the guide rail 650 of the upper sliding member 210 as shown in Figure 5a do.

In addition, the carrier body 230 has a latch 350 at the lower front end, as shown in Figure 5b, when the carrier pinion 450 leaves the third rack 250c, the upper sliding The stopper 330 provided on the guide rail 650 of the member 210 serves to stop the carrier body 230 at a predetermined position without any further sliding movement.

However, it should be noted that the installation position of the stopper 330 is not independent, but depends on the sliding length due to the difference in radius between the upper pinion 430 and the carrier pinion 450.

Meanwhile, FIG. 6 is a side view schematically showing a state in which the lower driving motor 370 of the lifting device 100 of the roof carrier for the vehicle according to the present invention is driven to perform a sliding movement of the lower sliding member 170, and FIG.
