And it relates to a space expansion type 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, if necessary, but the space is narrow, and a demand to increase space is issued.

Among them, a camper car can be operated like a general car, as well as an electric connection, it is difficult to self-water, and it is a vehicle that can live by moving to a place where water cannot be discarded through a sewer pipe, and it is a field that is gaining much popularity in recent years.

The basic components of a camper include a sleeping space, a space where you can sleep, a living space where you can eat, a kitchen space where you can cook food, a toilet space where you can see urine and urine, and a shower space where you can take a shower. It is common to have.

However, most of the camping cars used in Korea are imported from Europe or the United States, or manufactured by imitating them, and are made 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: sleeping space, living space, kitchen space, toilet space, and shower space, it must be 1.5 times larger than that of a general car. There is a problem in that it is difficult to park a camper in the space leisurely.

In addition, there is a problem in that driving a car in the city center or high-speed driving on a highway is difficult because the width of the domestic city road is narrow instead of the width of the camper car.

On the other hand, the terrain in Europe or the United States is a large flat land, most of the space is large, and there are many camping-only areas, so commercialization was easy.However, the domestic terrain consists of 70% mountains, so it is difficult to camp with a camper or move to a camping site. too big.

In addition, the small camping car (for example, Hyundai Starex-modified camping car), which is easy to park due to the above circumstances and characteristics in Korea, has inevitably removed toilets and showers among the five camping spaces. There is an inconvenient problem to use a camper.

In addition, the existing camping car has difficulty in installing the equipment because it has to work in a vehicle with limited space for five equipment, and there is a disadvantage that a vehicle cannot be used for repair or maintenance. In addition, when a problem occurs in camping facilities, it is difficult to distinguish whether a problem is caused by a car or a camping facility.

On the other hand, most food trucks are small trucks of about 1 ton, and the space is not large because the equipment is installed on the truck, and the height of the kitchen 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 in an exhibition hall or marketplace, the process of loading and transporting the goods in the store, then displaying the goods in the sales place again, and loading the goods into the automobile after the sale is finished, is repeated. This is inconvenient due to the repeated process of transportation and display.

I can. By the way, the method of lifting the corresponding part of the space expansion panel 200 upward is simple to construct the mechanical mechanism, whereas the floor surface of the space expansion panel 200 from the ground corresponds to the height (height of the vehicle). As it increases, there is a concern that structural stability may be deteriorated. On the contrary, since the method of lowering the corresponding part of the space expansion panel 200 downward is settled on the ground, structural stability is high, and the mechanical mechanism design is difficult.

In the space expansion module according to an embodiment of the present invention, the mechanical mechanism design is difficult, but in order to achieve the original purpose of the camper, the corresponding part of the space expansion panel 200 having excellent structural stability is lowered to expand the space. I took the way.

Here, a key configuration of a mechanical mechanism for lowering the corresponding portion of the space expansion panel 200 is an elevator unit.

2A to 8B and 12 to 14, the lower end of the lower outer expansion panel 213 of the outer expansion panel part 210 is supported between the guide frames 310 on both sides. The elevator lower frame 410 is connected to the combined elevator lower frame 410, the elevator upper frame 420 supported on the upper side of the docking upper frame 316 and moved, and the elevator lower frame 410 disposed under the elevator lower frame 410 It may include a scissor lift 510 provided to guide the lower moving of the) or the upper moving of the upper frame 420 of the elevator.

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 externally extends the space expansion panel 200 from the cargo loading space of the vehicle 100. It may be provided to be supported by the docking upper frame 316 of the configuration of the docking frame provided for sliding and moving.

Here, the elevator lower frame 410 is provided in the shape of a quadrangular frame in which approximately two are separated left and right, and a lower connection pole 413 is provided to extend upward at an upper portion of each corner, and the lower connection pole 413 is It serves to connect the lower inner expansion panel 253 and the upper inner expansion panel 251 to enable mutual sliding movement.

Docking upper frame 316, after the space expansion panel 200 is moved to the outside from the cargo loading space of the vehicle 100, the elevator upper frame 420 is separated from the elevator so as to be able to move up and down and docked again It may be moved horizontally along the upper guide rail 315 to the cargo loading space of the vehicle 100.

The elevator unit, when the scissor lift 510 coupled to the lower side of the elevator upper frame 420 is unfolded, the elevator lower frame 410 is landed on the floor in an operation that moves downward while maintaining the level, and then the elevator lower frame The lower outer expansion panel 213 seated on the elevator upper frame 420 is replaced with the upper outer expansion panel 211 by moving the elevator upper frame 420 downward while the scissor lift 510 is folded based on 410. You can slide and move downwards from the inside of ).

That is, the scissor lift 510 first lands the elevator lower frame 410 to the ground as the floor while fully unfolding downward based on the elevator upper frame 420, and then the elevator lower frame 410 in the landed state. The upper outer is expanded by a second landing operation of the components of the space expansion panel 200 (here, the lower outer expansion panel 213 and the lower inner expansion panel 253) while being completely folded downward based on The lower outer expansion panel 213 located inside the panel 211 and the lower inner expansion panel 253 located inside the upper inner expansion panel 251 slid downward at the same time, and the space where the ground is located The internal space of the expansion panel 200 can be completely expanded.

At this time, the lower outer due to the strong support of the upper connection pole 411 provided at the inner edge portion of the upper inner expansion panel 251 and the lower connection pole 413 provided at the outer edge portion of the lower inner expansion panel 253 The expansion panel 213 and the lower inner expansion panel 253 may stably slide and move.

Meanwhile, the elevator upper frame 420 and/or the elevator lower frame 410 may be provided with a lift driving unit 520 that folds or unfolds the scissor lift 510.

As for the scissor lift 510, as shown in FIGS. 5A, 5B, and 15, the two sliding plates 511 and 513 are coupled in a'X' shape around the center pin 512 in the center to provide external force Can be folded or unfolded by In addition, one end of the sliding plates 511 and 513 is hinged with the elevator lower frame 410 and the sliding plate pin 515, and the other ends of the sliding plates 511 and 513 are the elevator upper frame 420 and the sliding plate pin 515 ) Can be hinged. However, one end of the two sliding plates 511 and 513 connected to the elevator upper frame 420 or the elevator lower frame 510 is hinged through a nut block 523 in the configuration of the lift driving unit 520 to be described later. Can be combined.

The lift driving unit 520 is a screw 521 connected horizontally back and forth along the inner surface of the elevator lower frame 410 or the elevator upper frame 420, as shown in FIG. 5B, and rotationally driving the screw 521 It includes 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 the 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, in the configuration of the space expansion panel 200, after the lower outer expansion panel 213 and the lower inner expansion panel 253 are stably sliding and moved on the ground, the upper connection pole 411 and the lower connection pole ( By automatically or manually inserting the stopper pin 450 into the hole passing through each other 413, 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 moving.

The elevator unit is a device for lowering the space expansion panel 200 on the ground, which is the floor, and not only secures a space for a person to stand inside the space expansion panel 200, but also places the space expansion panel 200 on the floor. It can be positioned to increase stability.

(Landing part)

This is a system that supports the space expansion panel 200 on the floor. If the floor is flat, a bridge of a certain length can be installed, but there are many cases of irregularities on the floor, such as camping sites, so each corner independently moves independently from the support. 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 is a landing part that firmly supports the space expansion panel 200 seated on the ground, which is a floor, as shown in FIGS. 2A to 8B. It may further include.

The landing unit may be composed of a landing pedestal 610 folded on a lower edge of the lower elevator frame 410 as shown in FIGS. 5A and 5B and FIGS. 16 and 17. When the landing pedestal 610 is folded under the elevator lower frame 410, the lower outer expansion panel 213 and the lower inner expansion panel 253 of the space expansion panel 200 are lowered by the elevator lower frame 410. After sliding and moving, it is manually or automatically unfolded and seated on the ground, thereby stably seating the space expansion panel 200. The height of the landing pedestal 610 can be adjusted according to the state of the ground, so that the space expansion panel 200 may 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 scissor lift 510 is slightly raised so that the space expansion panel 200 positioned on the guide frame 310 is slightly upward from the guide frame 310 It is important to be separated. This is to separate and move the docking upper frame 316 into the cargo loading space of the vehicle 100 without interference from the space expansion panel 200. The elevator upper frame 420 by the scissor lift 510 is spaced a predetermined distance upward with respect to the docking upper frame 316, and the docking upper frame 316 is the space expansion panel 200 by the guide driving unit 320. It can be introduced into the cargo loading space of the vehicle 100 without any interference.

In this state, it is natural that the vehicle 100 and the space expansion panel 200 are completely separated, so that the vehicle 100 can be moved to the outside separately from the space expansion panel 200. Therefore, even when the space expansion module itself needs to be repaired or the vehicle needs to be repaired, there is an advantage that a normal vehicle or a space expansion module can be used separately during the repair.

(Extension)

To install camping facilities (kitchen, toilet, shower room, other facilities), cooking facilities, objects, etc. on the space expansion panel 200, and to move, prepare meals, and wash dishes inside the space expansion panel 200 I need space. To secure the space, there is a need to extend the space expansion panel 200 in the horizontal direction to the left or right.

When the docking part as described above is pulled out with the space expansion panel 200 to the outside of the cargo loading space of the vehicle 100, for example, due to the interference of the docking upper frame 316, the horizontal direction of the left or right Space expansion may not be possible. However, in the case of the space expansion module according to an embodiment of the present invention, after the space expansion panel 200 is inserted outside the vehicle and seated on the ground, the docking part is separated from the space expansion panel 200 and the vehicle 100 ) Of the cargo loading space, it has the advantage that the space can be expanded in the horizontal direction of the left or right side of the space expansion panel 200.

As shown in FIGS. 2A and 2B, the expansion part is provided in the inner support frame 710 provided to support the inner expansion panel 250 on the elevator upper frame 420 and the inner support frame 710. It may include a lower expansion slider 753 supporting the horizontal sliding movement of the left or right side of the inner expansion panel 250 with respect to the outer expansion panel part 210.

Here, a lower end of the lower inner expansion panel 253 and a lower end of the lower outer expansion panel 213 may be installed to be interconnected through the lower expansion slider 753. In addition, an upper end of the upper inner expansion panel 251 and an upper end of the upper outer expansion panel 211 may be installed to be interconnected via an 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 connected thereto, respectively, are separated from the upper expansion slider 751 and The inner space of the space expansion panel 200 may be expanded by sliding and moving in the horizontal direction to the left or right along the lower expansion slider 753.

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

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

As described above, after the inner space of the space expansion panel 200 is expanded by the elevator unit and the expansion unit, the operation sequence for re-entering the cargo loading space of the vehicle 100 is performed in the reverse order of the above-described expansion order, making it easy to Can be stored in a vehicle.

Until now, a space expansion module according to an embodiment of the present invention has been described in detail, but when the space expansion module is installed in a camper, it is natural that it has a meaning as a space expansion type camper.

That is, the space expansion type camper according to an embodiment of the present invention, as shown in Figs. 2A to 8B, any vehicle having a vehicle body having an empty space such as a cargo loading space in which the space expansion module can be placed In addition to being applicable to all vehicles, it includes all those provided to pull out the space expansion module by stopping at the place where there is a need for space expansion after being inserted and stored inside the cargo loading space when the vehicle 100 is moved. It is a concept.

That is, one embodiment of the space expansion type camper according to the present invention is provided to be interlocked with a vehicle body having a cargo loading space, an outer expansion panel portion provided to be withdrawn from the cargo loading space of the vehicle body to the outside, and an outer expansion panel portion. In addition, the outer expansion panel unit includes an inner expansion panel unit that is moved to the left or right with respect to the outer expansion panel unit from the outside of the cargo loading space to expand the inner space of the outer panel unit, and the outer expansion panel unit has at least one side of the left and right sides open. It is also open to the bottom, and at least one of the upper outer expansion panel and the left and right sides, which are provided to move in the front and rear horizontal direction, is open, is also open to the top, and is provided to be moved in a vertical direction with respect to the upper outer expansion panel. It includes a lower outer expansion panel, and the inner expansion panel part is provided to be movable in a vertical direction with respect to the upper inner expansion panel and the upper inner expansion panel provided to be movable in left and right horizontal directions from the open side of the upper outer expansion panel. And a lower inner expansion panel provided to be movable in a horizontal direction from an open side of the lower outer expansion panel.

In the above, an embodiment of a space expansion module and a space expansion type camper having the same according to the present invention has been described in detail with reference to the accompanying drawings. However, the embodiments of the present invention are not necessarily limited by the above-described embodiment, and it is natural that various modifications and implementations in an equivalent range by those of ordinary skill in the art to which the present invention pertains are possible. will be.
