Description

Technical Field

[0001] The utility model relates to the technical field of roof tent devices, in particular to a multi-link mechanism on a roof tent. Background Art

[0002] A rooftop tent is a portable sunshade and rest facility installed on the roof of a car, usually used for camping and outdoor activities. Its design allows users to quickly build a sheltered space when the vehicle is parked, providing additional living space and shade. Traditional rooftop tent support frames are generally telescopic and extend along the horizontal direction of the roof. Once opened, the maximum height of the tent is limited by the height of the roof, so the space inside the tent is very limited. Utility Model Content

[0003] 1. Technical issues

[0004] The utility model provides a multi-link mechanism on a roof tent, aiming to solve the problem that a traditional roof tent can only be extended horizontally, resulting in insufficient height and internal space.

[0005] (II) Technical content

[0006] In order to solve the above technical problems, the technical solution of the utility model is: a multi-link mechanism on a roof tent, including a fixed base and a movable base, the fixed base and the movable base are symmetrically arranged up and down and hinged plates are fixed on the opposite sides, the left and right ends of the hinged plate of the fixed base are respectively hinged with a third link and a fourth link, the left and right ends of the hinged plate of the movable base are respectively hinged with a first link and a second link, the second link and the fourth link cross and overlap and the intersection is hinged through a rotating shaft, the other end of the first link is hinged to the other end of the fourth link, and the other end of the third link is hinged to the other end of the second link.

[0007] Furthermore, through grooves are provided inside the third connecting rod and the fourth connecting rod for the first connecting rod and the second connecting rod to move.

[0008] Furthermore, the first connecting rod and the third connecting rod have the same length.

[0009] Furthermore, the second connecting rod and the fourth connecting rod have the same length.

[0010] (III) Technical Effect

[0011] Compared with the prior art, the utility model has the following advantages: the traditional roof tent is limited by the height of the roof and the internal space is limited, while the multi-link mechanism of the present invention can maintain a certain angle and rise to a certain height when unfolded, thereby creating a larger available space in the hardtop roof tent. This design allows users to enjoy a more comfortable standing and activity space in the tent, greatly improving the living comfort and user experience. The movable base in the mechanism drives the movement of the first, second, third, and fourth connecting rods during the lifting process, so that the height of the tent increases accordingly. As the movable base is raised, the angle between the movable base and the fixed base gradually increases, providing users with a more spacious internal space. BRIEF DESCRIPTION OF THE DRAWINGS
