Description

Tent for vehicles}

The present invention relates to a tent for a vehicle, and more specifically, the pillar supporting the tent is composed of four hydraulic cylinders in multiple stages, and the height thereof can be adjusted freely, as well as the assembly of the ceiling, the hydraulic cylinder, the side walls and the awnings. It relates to a vehicle tent that makes this simple and easy.

As the five-day work week increases leisure time, people are finding ways to enjoy their leisure activities, and the leisure industry is booming.

Leisure activities are different from each other, so we can't call them a specific one, but we can easily think of it as a trip, or think of a car trip to freely travel to where we want in a short time.

In addition, the advantage of such a car trip is that accommodation can also be solved directly where desired. However, the cumbersome and uncomfortable way of setting up or folding a tent for bedtime is to reduce your travel satisfaction.

These days, in order to make this easy and convenient, a vehicle tent has been developed that is installed on the roof of the vehicle and automatically unfolded and folded when in use so that the user can park in the desired position and sleep in the tent installed on the roof of the vehicle. .

However, in the conventional vehicle tent, the four hydraulic cylinders that function to support the folding and extending while supporting the roof are erected vertically at the same time as they are rotated as their length is extended, and when they are folded again, they are rotated and laid down. Since the structure is complicated and the components such as expensive LM guides are needed to make the operation smooth, there is a disadvantage in that the economy is low, such as an increase in installation cost. In addition to the simple function of folding or unfolding the height of the roof, the function of adjusting the height of the tent could not be carried out.

In addition, there is a disadvantage that the coupling state between the top and the ceiling of each hydraulic cylinder is not easy and the coupling state is not firm, and the connection part connecting the upper and lower ends of the side wall and the roof or the floor is simply connected by adhesive, riveting or stitching. Because of this, a lot of defects occur, workability is lowered, and when broken, the repair is difficult and time consuming.

The present invention has been made to solve the above-mentioned disadvantages, the purpose of the four hydraulic cylinders that function to fold or unfold while supporting the roof is simple, but can fully perform the function and the height of the roof It is to provide a vehicle tent that can be adjusted freely.

Another object of the present invention is to provide a coupling structure that makes the coupling between the top and the ceiling of each hydraulic cylinder simple and robust, as well as easy to work.

Another object of the present invention is to facilitate the repair work in case of breakage of parts.

The present invention for achieving the above object,

In the tent is installed on the roof of the vehicle consisting of a main body forming a floor, a roof which is raised and lowered on the upper portion and a plurality of cylinders to raise and lower the roof and side walls connecting the roof and the main body,

The cylinder is operated by a separate hydraulic drive circuit as a multi-stage hydraulic cylinder that rises and falls up and down, and the upper end of the hydraulic cylinder is achieved by screwing the coupling hole installed on the roof.
