And a space-extended camper having the same.

Small trucks or vans are used in various fields, such as camping cars, food trucks, and transportation vehicles that sell goods as needed, but the space is so narrow that there is a demand to increase space.

Among them, the camper is a vehicle that can be operated like a general car, and is an automobile that can move to and live in a place where it is difficult to self-supply without electricity connection and cannot drain water through a sewer pipe.

The basic components of a camping car include a sleeping area, which is a sleeping area, a living room where you can eat, a kitchen area that is a food making area, a bathroom area that can be used to watch urine, and a shower room area that can take a shower. It is common to have.

However, most of the campers used in Korea are imported from Europe or the United States, or manufactured by imitating them and suitable for Europe or the United States for a long time, and there are many parts that do not fit the domestic conditions as follows.

Specifically, in order to have five spaces: a sleeping area, a living area, a kitchen area, a bathroom area, and a shower area, it must be at least 1.5 times larger than a regular car, so the area around most residential areas in Korea, especially apartment parking lots There is a problem that it is difficult to park a camper in the space effortlessly.

In addition, instead of having a wide car width of a camper car, there is a problem in that it is difficult to drive a car in the city center or to drive at a high speed on a highway due to the narrow domestic city road width.

On the other hand, the terrain in Europe or the United States is a large flat land, and most of the space is large and there are many camping areas, so it is easy to commercialize. However, the domestic terrain is 70% made of mountains. too big.

In addition, due to the above-mentioned circumstances and special characteristics in Korea, small campers (e.g. Hyundai Starex modified campers) that are easy to park are inevitably deleted toilets and showers among the five camping spaces, and kitchens are also placed outside in cold winters. There is an inconvenient problem to use the camper.

In addition to this, the existing camper car has a drawback in that it is difficult to install the facility because it must work in a vehicle with limited space for 5 facilities, and the vehicle cannot be used for repair or maintenance. In addition, when a problem occurs with a camping facility, it is difficult to distinguish whether a car is a problem or a camping facility, and it is difficult to distinguish a clear responsibility between a car company and a camper installation company.

On the other hand, most of the food trucks are small trucks of about 1 ton, so the space is not large because the equipment is installed on the truck, and the kitchen height for making food is high. Therefore, there is a demand for space expansion.

On the other hand, in the case of a transport vehicle that sells goods at an exhibition hall or marketplace, the process of loading and transporting the goods at a store, displaying the goods at the sales place again, and then loading them into a car after the sale is over are repeated. This is inconvenient due to the repeated process of transportation and display.

As a method of expanding the space of the space expansion panel 200 drawn out from the cargo loading space of the vehicle 100, a method of raising the height of the space expansion panel 200 upward and lowering it downward may be considered. You can. By the way, the method of lifting the corresponding portion of the space expansion panel 200 upward is simple to construct its mechanical mechanism, while the bottom surface of the space expansion panel 200 from the ground corresponds to the garage (height of the vehicle). As it is high, there is a fear that structural stability is deteriorated. On the contrary, since the method of lowering the corresponding portion of the space expansion panel 200 downward is secured to the ground, there is a problem in that mechanical mechanism design is difficult instead of having high structural stability.

In the space expansion module according to an embodiment of the present invention, although mechanical mechanism design is difficult, the space of the space expansion panel 200 having excellent structural stability is extended downward to achieve the original purpose of the camper. The way was taken.

Here, the core configuration of the mechanical mechanism for lowering the corresponding portion of the space expansion panel 200 downward is the elevator unit.

As shown in FIGS. 2A to 8B and 12 to 14, the elevator unit supports the lower end of the lower outer expansion panel 213 among the guide frames 310 on both sides of the configuration of the outer expansion panel unit 210. Elevator lower frame 410 while interconnecting the elevator lower frame 410 to be coupled with the upper frame of the docking upper frame 316 and moving the upper frame 420 of the elevator and the lower frame 410 of the elevator. ) May include a scissor lift 510 provided to guide moving below or moving above the elevator upper frame 420.

More specifically, the lower end of the lower outer expansion panel 213 is supported on the elevator lower frame 410, and the elevator lower frame 410 is external to the space expansion panel 200 from the cargo loading space of the vehicle 100. Of the configuration of the docking frame provided for sliding and moving, it may be provided to be supported by the docking upper frame 316.

Here, the elevator lower frame 410 is provided in a quadrangular frame shape with approximately two separated from left and right, and a lower connecting pole 413 is provided at the top of each corner to extend upward, and the lower connecting pole 413 is It serves to connect the lower inner expansion panel 253 and the upper inner expansion panel 251 to allow sliding sliding.

Docking upper frame 316, after the space expansion panel 200 is moved from the cargo loading space of the vehicle 100 to the outside, the upper frame 420 of the elevator is separated from the elevator to enable vertical movement, and docked again Along the upper guide rail 315, it may be horizontally moved to the cargo loading space of the vehicle 100.

When the scissor lift 510 coupled to the lower side of the upper frame 420 of the elevator is unfolded, the elevator lower frame 410 is moved downward while maintaining the horizontal level, and then landed on the floor that is the floor, and then the lower frame of the elevator. The lower outer expansion panel 213 seated on the upper frame 420 of the elevator in an operation of moving the upper frame 420 of the elevator downward while the scissor lift 510 is folded based on the 410 upper upper expansion panel 211 ) It can be moved sliding from the inside to the bottom.

That is, the scissor lift 510, while being fully extended downward with respect to the elevator upper frame 420, first lifts the elevator lower frame 410 to the ground as the floor, and then lifts the elevator lower frame 410 in the landed state. Expanding the upper outer portion by folding the second part of the configuration of the space expansion panel 200 (here, the lower outer expansion panel 213 and the lower inner expansion panel 253) to the ground, which is completely folded downward with reference to The lower outer expansion panel 213 positioned inside the panel 211 and the lower inner expansion panel 253 positioned inside the upper inner expansion panel 251 are simultaneously sliding downwards and moved downward, where the ground is located. The interior space of the expansion panel 200 can be completely expanded.

At this time, the lower outer by the solid support of the upper connecting pole 411 provided in the inner edge portion of the upper inner expansion panel 251 and the lower connecting pole 413 provided in the outer edge portion of the lower inner expansion panel 253 The expansion panel 213 and the lower inner expansion panel 253 may be stably movable.

On the other hand, the elevator upper frame 420 and / or the elevator lower frame 410 may be provided with a lift driver 520 for folding or unfolding the scissor lift 510.

Scissor lift 510, as shown in Figures 5a, 5b and 15, the center of the center pin 512, the center of the two sliding plates (511,513) is combined with an'X' shaped external force supplied It can be folded or unfolded. In addition, one end of the sliding plates 511 and 513 is hinged to the elevator lower frame 410 and the sliding plate pins 515, and the other ends of the sliding plates 511 and 513 are elevator top frames 420 and the sliding plate pins 515. ) Can be hinged. However, one end connected to the upper frame 420 of the elevator or the lower frame 510 of the two sliding plates 511 and 513 is hinged by the nut block 523 among the components of the lift driving unit 520 to be described later. Can be combined.

And a nut block 523 that moves back and forth along the screw axis according to the rotation of the motor 522 and the screw 521. Here, as described above, the nut block 523 is hinged to one end of two sliding plates 511 and 513, so that when the nut block 523 is moved in the front-rear direction along the screw 521, the two The sliding plates 511 and 513 are folded or unfolded around the center pin 512.

In addition, after the lower outer expansion panel 213 and the lower inner expansion panel 253 of the space expansion panel 200 are stably sliding on the floor, the upper connecting pole 411 and the lower connecting pole ( 413) By automatically or manually inserting the stopper pin 450 into the hole penetrating each other, the upper connecting pole 411 and the lower connecting pole 413 are integrally connected, so that the upper outer expansion panel is moved toward the lower outer expansion panel by its own weight. It can be fixed to each other more stably by preventing downward movement.

The elevator unit is a device that lowers the space expansion panel 200 to the ground, which is a floor, so that a person can not only secure a space to stand inside the space expansion panel 200, but also attaches the space expansion panel 200 to the ground, which is the floor. It can be placed to increase stability.

(Landing part)

As a system for supporting the space expansion panel 200 on the floor, if the floor is flat, a leg of a certain length may be installed, but since there are many irregularities on the floor, such as a camping ground, it is independent of a support that moves independently at each corner. It can be said that a mechanical mechanism capable of height adjustment is essential.

To this end, an embodiment of the space expansion module according to the present invention, as referenced in FIGS. 2A to 8B, a landing part that firmly supports the space expansion panel 200 seated on the ground that is the floor. It may further include.

After sliding and moving, it is spread manually or automatically and seated on the ground, thereby stably seating the space expansion panel 200. According to the state of the ground, the height of the landing pedestal 610 is provided to be adjustable, so that the space expansion panel 200 can have a position parallel to the ground.

At this time, while the height of the landing pedestal 610 is in contact with the ground, the space expansion panel 200 positioned on the guide frame 310 by slightly raising the scissor lift 510 is slightly upward from the guide frame 310. It is important to keep them apart. This is to move the docking upper frame 316 into the cargo loading space of the vehicle 100 without interfering with the space expansion panel 200. The elevator upper frame 420 by the scissor lift 510 is spaced a predetermined distance upward from the docking upper frame 316, and the docking upper frame 316 is a space expansion panel 200 by a guide driving unit 320 And may enter the cargo loading space of the vehicle 100 without any interference.

In this state, the vehicle 100 and the space expansion panel 200 are completely separated, so it is natural that the vehicle 100 can be moved to the outside separately from the space expansion panel 200. Accordingly, even when repair of the space expansion module itself or repair of the vehicle is required, it has an advantage of using a normal vehicle or space expansion module separately during repair.

A lower expansion slider 753 that supports sliding movement in a horizontal direction to the left or right of the inner expansion panel 250 with respect to the outer expansion panel unit 210 may be included.

Here, the lower end of the lower inner expansion panel 253 and the lower end of the lower outer expansion panel 213 may be installed to be interconnected via a lower expansion slider 753. In addition, the upper end of the upper inner expansion panel 251 and the upper end of the upper outer expansion panel 211 may be installed to be interconnected via the upper expansion slider 753. Therefore, when a force is applied to the lower expansion slider 753 and the upper expansion slider 753 by manual or mechanical operation, the upper inner expansion panel 251 and the lower inner expansion panel 253 respectively connected to the upper expansion slider 751 and The inner space of the space expansion panel 200 may be extended by sliding and moving in a horizontal direction to the left or right along the lower expansion slider 753.

On the other hand, although not shown in the drawing, a separate landing frame (not shown) may be provided under the extended lower inner expansion panel 253 to ensure support with the ground.

It is possible to secure a predetermined moving space and passage that can be moved to make food or take a shower in the kitchen by an expansion unit that expands the space expansion panel 200 in the horizontal direction to the left or right.

As described above, after the interior space of the space expansion panel 200 is expanded by the elevator unit and the expansion unit, the operation sequence for entering the cargo loading space of the vehicle 100 again proceeds in the reverse order of the expansion sequence described above. It can be stored as a vehicle.
