[0002] With the rise of traveling in recent years, more and more people choose self-driving tours, especially during holidays, the number of people traveling has exploded. In order to get a good rest during the journey, tents that can be installed on the roof have become a necessity for many people. Roof tents will not take up storage space in the car. When the user needs it, the roof tent can be unfolded so that the user can rest in the tent in time.

[0003] However, most of the roof tents on the market are operated by manpower, which is time-consuming and laborious to unfold and fold. In addition, the structure of the roof tent is relatively complicated, and it is easy for the roof tent to get stuck due to improper operation of the user, which greatly reduces the user experience and makes the use of the roof tent inconvenient.
