[0002] A rooftop tent is a tent that can be set up on the roof of a car. Because it is not as close to the ground as other tents, it is not easily invaded by ground air and moisture, making it more comfortable to use and popular among people. When not in use, the rooftop tent can be folded directly on the roof of the car for easy transportation.

[0003] Rooftop tents come in a variety of forms. A foldable rooftop tent is generally formed by two support plates pivoted to form an integral frame. As shown in patent CN214035024U, the tent frame is mainly composed of a front support plate, a rear support plate and a ladder. The rear end of the front support plate is movably pivoted to the front end of the rear support plate. The ladder is arranged at the front end of the front support plate, and the rear support plate is fixed on the roof. The structure is relatively stable, but the front support plate is suspended. The front support plate is only supported by the ladder at its front end. The structure is not stable enough and is easy to shake. The bearing capacity is also small, and it cannot load heavy objects, which affects the user experience. Moreover, the patent only uses the front support plate and the rear support plate as the bottom frame of the tent frame, which is a two-fold structure. When the tent is folded, the accommodation space between the front support plate and the rear support plate is small, and it is difficult to store the tent cloth and other frame structures. When the tent is unfolded, the activity space in the tent is limited by the front support plate and the rear support plate. Utility Model Content
