In general, camping caravans provide living spaces such as bedrooms, kitchens, shower rooms, and living rooms inside a truck or bus, so that they can stay, cook, wash, rest, etc., and have at least two wheels. Living spaces such as bedroom, kitchen, shower room, and living room are provided inside the trailer to be used for accommodation, cooking, washing, rest, etc. It refers to things that perform the same function as home during outdoor leisure activities such as , riding, camping, etc.

Because these caravans are free to move, they are not restricted by location, and because living spaces such as bedrooms, kitchens, showers, and living rooms are provided in the vehicle or trailer, you can get the comfort of home compared to tents, TV, audio Due to the advantages of being able to use electrical appliances such as , rice cookers, refrigerators, etc., it is very popular with people who enjoy outdoor leisure activities such as travel, mountain climbing, fishing, riding, and camping in addition to those who enjoy existing camping. As a result, the number of users is rapidly expanding.

In addition, in the case of a limited campsite, it is difficult to make a reservation, you have to submit the campsite use fee, and the space used in the campground is limited, and the inconvenience of using the toilet, shower, washroom, and dishwasher in common is also caused by the caravan. This is one factor in the expansion of the use of

In addition to existing lodging facilities such as hotels, motels, and condominiums, to provide more nature-friendly and different themes, or to increase profits rather than simply renting a space at a campsite, accommodation is provided in a caravan at a campground, pension, or resort. places are also increasing.

Such a caravan needs to maintain a balance so that a user can enter and live inside, but since a buzzing phenomenon occurs due to suspense of the vehicle, the lower part of the vehicle is supported by a jockey or the like.

In particular, in the case of a towed trailer, since the wheel is provided on only one side opposite to the tow hook of the trailer, fixing of at least one axle is absolutely necessary.

In addition, due to the nature of caravans that are parked outdoors, if a caravan camp is not created artificially, there are many cases where it is orthogonal to an inclined position. In order to ensure stable drainage of the back and to maintain a stable posture of the user while living in the caravan, it is necessary to keep the horizontal surface of the caravan flat despite the slope of the floor.

As a part of maintaining the posture of the caravan horizontally even on an inclined floor surface, in Patent Publication No. 2020-0022182 (published date: March 03, 2020) cited herein as a prior document, as shown in FIG. Similarly, air pressure is injected into the pair of first cylinders 21 and the pair of second cylinders 31 (located on the back surface of the first cylinder 21 and not shown in the drawing) or the pair of first cylinders ( 21) and by opening the discharge valves of the pair of second cylinders 31 to discharge the air pressure injected into the pair of first cylinders 21 and the pair of second cylinders 31, the pair of first By adjusting the lengths of the balance maintaining parts 20a and 20b and the pair of second balance maintaining parts 30a and 30b, to maintain the balance of the main body 10, stable stopping is possible even in an inclined position. The invention is disclosed. Here, Figure 1 is an exemplary view of maintaining the balance of the caravan by the first cylinder and the second cylinder according to the prior art.

In this prior document, as shown in FIG. 2, the first position sensor 42a to the fourth position sensor 42d are disposed at each corner of the body 10, or as shown in FIG. 3, the body 10 is divided into 1 to 9 regions, calculates the pressure center position and compares it with a threshold value. By injecting or discharging air pressure to the cylinder 21 and the pair of second cylinders 31, the main body 10, that is, the balance of the caravan as a whole is maintained. Here, FIG. 2 is an exemplary diagram illustrating an example of arrangement and area division of a position sensor according to the prior art, and FIG. 3 is an exemplary view illustrating an example of arrangement and area division of a position sensor according to the prior art.

However, this configuration is only for keeping the body of the caravan horizontally on the inclined surface, and does not consider the friction limit of the floor surface. That is, a pedestal is provided at the lower end of the balancing part to prevent the balancing part for maintaining the balance of the caravan from penetrating into the ground and to increase the frictional force on the slope. There is a risk of the caravan slipping or overturning if severe.

In particular, due to the nature of the caravan that is stagnant outdoors, it is often not possible to stop the caravan on a hard surface such as cement or asphalt that can withstand the load of the caravan, and the caravan user often finds a place to stop the caravan on the ground rather than where it is frequently visited. It is highly likely that the characteristics are not accurately understood. In addition, even if the caravan is installed in the campground, the ground is not hard in the case of a newly constructed campground.

Moreover, in bad weather conditions where heavy rain falls while the caravan is stopped, the ground may become soft due to heavy rain due to the nature of the outdoor ground, which is mainly soil.

Due to the above-described circumstances and causes, in the balancing device according to the prior art, the balance of the caravan body itself, that is, even if the level is maintained, the inclination of the caravan is increased while the load of the caravan is applied to the ground in the pedestal part, so that the inclination of the pedestal on the inclined surface is the friction limit. If it deviates, there is a risk that the caravan slides on the slope or overturns if severe.

This problem is caused by the ground is too soft to withstand the weight of the caravan, or the hardness of the ground is sharply reduced due to the influence of weather such as rain. If the balance itself is disrupted and overturns, there is a risk of causing a serious human accident.
