Description

Mobile camping trailer {A mobile camping trailer}

The present invention relates to a mobile camping trailer.

Recently, due to the increase in leisure time and the development of leisure culture, the number of people going outdoors on holidays or weekends is increasing. In particular, when vacations are extended due to holidays, recreational methods such as using a separate camping trailer to provide lodging and meals outdoors are gaining popularity.

Although these conventional camping trailers were created with the goal of providing vehicle space for living while moving to improve convenience in outdoor life, they are manufactured on a larger scale than ordinary vehicles to provide household goods and a resting space inside. . Due to this problem, typical camping trailers have the inconvenient problem of requiring a lot of space to carry and use.

To solve this problem, an assembly and installation camping trailer was designed, which was an improvement over the conventional method. However, these camping trailers have a complicated assembly process, so they are easily broken due to user carelessness, and parts are lost, making it impossible to reuse them. Additionally, because the exterior of the trailer is made of a light and weak material like a tent, there is a problem that it is easily damaged during handling by the user.

The purpose of the present invention is to provide a camping trailer that can be divided into a portable state and a deployed state, has a compact structure in the portable state and is easy to transport, and can provide sufficient living space like a conventional camping trailer in the deployed state. .

The above object is to provide a mobile camping trailer according to the present invention, a driving unit including a plurality of wheels and a wheel axle supporting the plurality of wheels, a floor supported by the driving unit and formed horizontally with respect to the ground, and a A trailer lower portion having a wall protruding upward from the trailer and an opening formed by the wall, a towing portion protruding from one end of the trailer lower, an outer wall covering the wall of the trailer lower, and a portion of the outer wall and the lower portion of the trailer. A portable state in which the upper trailer has a ceiling that covers the opening, the outer wall of the trailer upper descends along the wall of the lower trailer, and the upper trailer and lower trailer come close to each other, and the deployment in which the upper trailer is raised and supported from the lower trailer. A mobile camping trailer, characterized in that it has a lifting unit that raises and lowers the upper part of the trailer from the lower part of the trailer when in the portable state or the deployed state.

In addition, when the slider is interposed between the wall surface and the outer wall surface and guides the lifting and lowering movement path when the upper part of the trailer is raised and lowered by the lifting unit, the transition between the carrying state and the deployed state of the camping trailer is reduced. It assists you to perform it easily even with strength.

In addition, when the lifting unit has at least one hydraulic cylinder including a housing integrally formed inside the outer wall and a cylinder integrally formed inside the wall, the carrying state and the deployed state are switched by hydraulic force. By assisting, the transition between each state is made quickly, and by assisting the support of the upper part of the trailer when deployed, a more solid support state can be maintained.

In addition, if the door part is folded from the bottom of the lower part of the trailer and, in the deployed state, stands parallel to one end of the wall and the outer wall to assist in maintaining the deployed state, the door part is easy to carry. In addition, in the deployed state of the camping trailer, the door part can be used for entry and exit while providing the additional effect of firmly maintaining support in the deployed state.

In addition, the trailer upper part further includes a solar collector disposed along the outer wall of the ceiling, a power generator that generates power by the solar collector, and a power storage unit that stores the power charged from the power generator. , it is possible to provide a trailer with a more compact structure by generating power without building a separate device for power generation inside or outside the trailer.

Hereinafter, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily practice the present invention.

Hereinafter, terms such as upper, lower, upper, lower, etc. are used to distinguish the relative positions of components. For example, for convenience, when the upper part of the drawing is called upper and the lower part of the drawing is called lower, in reality, the upper part can be called lower, and the lower part can be called upper without departing from the scope of the present invention. .

Figure 1 is an internal perspective view of the camping trailer 10 according to the present invention, Figure 2 is a diagram showing the portable state of the camping trailer 10 according to the present invention, and Figure 3 is a drawing of the camping trailer 10 according to the present invention. Figure 4, a drawing showing the deployed state, is a diagram showing the use of a camping trailer according to the present invention.

1 to 4, the mobile camping trailer 10 according to an embodiment of the present invention is supported at one end by the vehicle 20. A towing unit 400 directly connected to the vehicle 20, a trailer lower part 200 connected to one end of the towing unit 400, a driving unit 100 supporting the lower trailer 200, and a trailer covering the lower trailer 200. It consists of an upper part (300).

The driving unit 100 supports the camping trailer 10 and is equipped with wheels 110 necessary for movement. As shown in FIG. 1, the plurality of wheels 110 driven when the camping trailer 10 moves have a structure of two as a pair, and between the two wheels 110 is a wheel axle connecting the wheels 110. (120) is formed. In addition to the form shown in FIG. 1, these wheels 110 can form a set of four wheels to form a stable support structure like a typical vehicle.

A trailer lower part 200 is formed on the upper part of the driving unit 100. The trailer lower part 200 is formed with a bottom 210 and has a structure directly connected to the driving unit 100. On the bottom 210, there is a wall 220 that forms the outer wall of the trailer, and at one end of the wall 220. It includes a formed door part 230 and various types of furniture parts 240 disposed inside the wall surface 220.

The bottom portion 210 refers to a plate-shaped portion made of a high-strength metal material. The lower end of the floor part 210 is connected to the driving part 100 and the traction part 400. Since the upper surface of the floor 210 can be used as a space for people to come and go, the furniture 240 is placed on the wall 220. For the user's convenience, the upper surface of the bottom 210 may be made of a softer material other than metal.

The wall 220 refers to a portion that protrudes from the bottom 210 and is formed perpendicularly from the ground. The wall 220 forms the exterior of the trailer and can also be used as an element to limit the interior space. A door portion 230 is disposed at one end of the wall surface 220. Generally, the door portion 230 shares one side of the wall 220 and serves as a passage that allows people to enter and exit the trailer. The furniture unit 240 collectively refers to various elements placed inside the trailer for convenience of living. As shown in Figure 1, drawers, closets, shower facilities, beds, refrigerators, sinks, etc. may be included. Due to the nature of the camping trailer 10, it is preferable that the furniture unit 240 is fixed at a specific location, and for this fixation, it can be supported by a separate fixing device. In addition, in order to safely fix the furniture part 240, a restriction may be imposed that the two surfaces of the floor part 210 and the wall surface 220 must be in contact.

The trailer upper part 300 covers the trailer lower part 200 and is a cubic structure that covers one open side of the trailer along the wall 220 belonging to the trailer lower part 200. The trailer upper part 300 has a ceiling part 310 that covers the opening 250 of the trailer lower part 200, an outer wall surface 320 that covers the wall surface 220, and a door on the outer wall surface 320. It includes a door cutout 330 that is cut along the shape of the door so that it can exist, and a solar panel 340 that is disposed on the ceiling 310 and collects sunlight.

The external shape of the trailer upper part 300 and the trailer lower part 200 can be changed depending on the use or movement situation of the trailer. When moving the trailer, the volume of the trailer can be minimized by switching to a portable state where the lower part of the trailer (200) and the upper part of the trailer (300) are close together. In addition, when the trailer is stopped and the internal space is used, the used space can be optimized in some cases, such as by moving the upper part of the trailer 300 away from the lower part of the trailer and switching to the deployed state to maximize the internal space.

This deformation is achieved by the lifting part 500. The lifting unit 500 is preferably utilized between the wall surface 220 of the trailer lower part 200 and the outer wall surface 320 of the trailer upper part 300.

The lifting unit 500 includes a cylinder housing 510 integrally formed inside the wall 220 or the outer wall 320, and a cylinder 520 integrally formed inside the other wall. When viewed from the inside, a plurality of such cylinders are arranged along the circumferential direction of the wall 320 to assist in the lifting and lowering of the trailer upper part 300. In the case of having such a lifting unit 500, the transition between the carrying state and the deployed state is assisted by hydraulic force, so that each state can be changed quickly, and the camping trailer 10 is sturdy by assisting in supporting the upper part of the trailer in the deployed state. Allows you to maintain support.

Raising and lowering by the lifting unit 500 may be assisted by various configurations in addition to the cylinder 520. For example, if a slider 530 that guides the lifting and lowering movement path is further included so as to have rails and grooves between the wall surface 220 and the outer wall surface 320, the lifting and lowering movement path of the trailer upper part 300 is further included. It guides the camping trailer (10) so that it can be easily switched between the carrying state and the deployed state with little effort.

Meanwhile, during this transition process, the door part 230 and the furniture part 240 placed inside the trailer may become an obstacle. In particular, the door part 230 must be fixed to the bottom part 210 of the trailer lower part 200 and maintained in an upright state, so it is difficult to utilize it as is due to the nature of the camping trailer 10, which has a variable height. . To solve this problem, the door part 230 may be arranged in a foldable manner so that it can rotate around the tangent line between the bottom part 210 and the door part 230. In this case, in the deployed state, it can stand up parallel to one end of the wall surface 220 and the outer wall surface 320 to assist in maintaining the deployed state, which not only makes it easy to handle the door part 230 when changing states, but also makes it easier to handle the camping trailer. It can provide the additional effect of firmly maintaining support in the deployed state of (10).

Aside from the above, there are many cases where a separate power generation device is needed to provide energy such as electricity along with the furniture unit 240 inside the camping trailer 10. It can be used by linking with a vehicle, but in some cases, more power is needed than the vehicle can produce.

For this purpose, a solar panel 340 may be formed on the externally exposed surface of the ceiling portion 310 of the trailer upper portion 300. The solar panel 340 formed in this way includes a solar collector 341 disposed along the outer wall, a power generator 342 that generates power by the solar collector, and the power charged from the power generator 342. If the power storage unit 343 is further included, it is possible to provide a trailer with a more compact structure by producing power without building a separate device for power generation inside or outside the trailer.

With the above configuration, the camping trailer 10 according to the present invention can be raised and lowered by the lifting part 500 formed inside the trailer lower part 200 and the trailer upper part 300, thereby moving the camping trailer 10. By easily switching between the portable state and the deployed state of operating inside the camping trailer (10), it is possible to provide a camping trailer (10) that is compact but has a large space.
