[0037] The embodiment of this application discloses a folding roof opening and closing structure.

[0038] Embodiment 1

[0039] Referring to Figure 1 , in this embodiment, a folding roof opening and closing structure includes a fixed seat 1, a main goose arm 2 rotatably connected to the fixed seat 1, and a first connecting rod 3. The fixed seat 1 is two steel beams welded to both sides of the vehicle body respectively. The main goose arm 2 and the first connecting rod 3 are both arc-shaped as a whole and are rotatably connected to the fixed seat 1. One end of the main goose arm 2 away from the fixed seat 1 is rotatably connected to a secondary goose arm 4. The end of the first connecting rod 3 away from the fixed seat 1 is rotatably connected to the end of the secondary goose arm 4 close to the main goose arm 2. The main goose arm 2, the first connecting rod 3, and the secondary goose arm 4 are all made of aluminum alloy, and the main goose arm 2 and the secondary goose arm 4 have a hollowed-out weight reduction design, which reduces their own weight on the premise of ensuring their strength. In other embodiments, the main goose arm 2, the first connecting rod 3, and the secondary goose arm 4 can be made of steel or composite materials.

[0040] Referring to Figure 1 , Figure 2 and Figure 4 , in this embodiment, one end of the main goose arm 2 close to the fixed seat 1 is rotatably connected to a tarpaulin connecting rod 5. One end of the tarpaulin connecting rod 5 away from the main goose arm 2 is rotatably connected to a tarpaulin support rod 6. The extending direction of the tarpaulin support rod 6 is perpendicular to the rotation plane of the tarpaulin connecting rod 5. One end of the secondary goose arm 4 close to the connection with the main goose arm 2 is provided with a cross beam 11 for supporting the tarpaulin. The extending direction of the cross beam 11 is perpendicular to the rotation plane of the secondary goose arm 4. The tarpaulin is installed between the cross beam 11 and the tarpaulin support rod 6. A first connecting rod transmission assembly 7 is provided among the first connecting rod 3, the tarpaulin connecting rod 5, and the tarpaulin support rod 6. When the main goose arm 2 rotates, the secondary goose arm 4, the tarpaulin connecting rod 5, and the tarpaulin support rod 6 are swung along a preset trajectory through the first connecting rod transmission assembly 7.

[0041] Specifically, the first link transmission assembly 7 includes a second link 71 and a third link 72. One end of the second link 71 is rotatably connected to one end of the first link 3 close to the fixed seat 1, and the other end of the second link 71 is rotatably connected to one end of the tarpaulin link 5 close to the main gooseneck 2. One end of the third link 72 is rotatably connected to the middle part of the second link 71, and the other end of the third link 72 is rotatably connected to the tarpaulin support rod 6. Both the second link 71 and the third link 72 are made of aluminum alloy. When the main gooseneck 2 rotates counterclockwise, the first link 3 drives the sub-gooseneck 4 to rotate clockwise around the rotating shaft rotatably connected to the main gooseneck 2, so as to realize the folding of the sub-gooseneck 4 and the main gooseneck 2. The main gooseneck 2 drives the tarpaulin link 5 and the third link 72 to swing counterclockwise, so that the tarpaulin support rod 6 rotates clockwise around the rotating shaft rotatably connected to the tarpaulin link 5, so as to realize the folding among the tarpaulin support rod 6, the tarpaulin link 5 and the main gooseneck 2.

[0042] Referring to Figure 1 , Figure 2 and Figure 4 , in this embodiment, a forearm 8 is provided at one end of the sub-gooseneck 4 facing away from the main gooseneck 2. The material of the forearm 8 is the same as that of the main gooseneck 2 or the sub-gooseneck 4 and also has a hollowed-out weight reduction design.

One end of the fourth link 91 is rotatably connected to one end of the main gooseneck 2 facing away from the fixed seat 1, and the other end of the fourth link 91 is rotatably connected to the forearm 8. One end of the fifth link 92 is rotatably connected to the middle part of the fourth link 91, and the other end of the fifth link 92 is rotatably connected to one end of the forearm 8 close to the fourth link 91. One end of the sixth link 93 is rotatably connected to one end of the sub-gooseneck 4 away from the main gooseneck 2, and the other end of the sixth link 93 is rotatably connected to one end of the forearm 8 facing away from the sub-gooseneck 4.

In other embodiments, the fourth link 91, the fifth link 92, and the sixth link 93 can also be made of aluminum alloy, and the surface can be treated with a coating to enhance the corrosion resistance.

[0045] Refer to Figure 1 、 Figure 2 and Figure 4 In this embodiment, a tarpaulin top plate 13 is fixedly installed on the front arm 8. The tarpaulin top plate 13 is made of a composite material. A tarpaulin is installed between the tarpaulin top plate 13 and the cross beam 11. The side of the tarpaulin top plate 13 facing away from the front arm 8 is used to abut against the front part of the vehicle. Reinforcing ribs are provided on the back of the tarpaulin top plate 13 to improve the overall rigidity and prevent deformation during long-term use. The tarpaulin top plate 13 and the tarpaulin are glued together with glue to ensure that the tarpaulin can be firmly fixed during movement and avoid wrinkles. In other embodiments, the connection between the tarpaulin top plate 13 and the tarpaulin adopts an elastic strut structure, and the tarpaulin is fixed on the tarpaulin top plate 13 by arranging elastic struts at the edge of the tarpaulin top plate 13.

[0046] Refer to Figure 1 and Figure 3 In this embodiment, a drive assembly 10 for driving the main goose arm 2 to rotate around the fixed seat 1 is installed in the fixed seat 1. The drive assembly 10 includes a telescopic drive member 101, a drive rack 102, and a driven gear 103. The telescopic drive member 101 is welded to the fixed seat 1. The telescopic drive member 101 can be a cylinder, a hydraulic cylinder, or an electric push rod. The drive rack 102 is welded to the output end of the telescopic drive member 101. The extending direction of the drive rack 102 is the same as the movement direction of the output end of the telescopic drive member 101. A chute is provided on the side of the drive rack 102 to cooperate with the slide rail in the fixed seat 1 to ensure that the drive rack 102 slides linearly along the fixed seat 1. The driven gear 103 is welded to the central axis of the main goose arm 2 rotatably connected to the fixed seat 1 and can rotate together with the main goose arm 2. The meshing between the drive rack 102 and the driven gear 103 adopts a precise meshing design to reduce wear during operation and improve the smoothness and reliability of the opening and closing process. A rear arm 12 is also welded to the fixed seat 1. The rear arm 12 is connected to the tarpaulin support rod 6 to support the tarpaulin and abut the tarpaulin against the opening of the tarpaulin storage bin of the vehicle to prevent the tarpaulin from shaking or being damaged due to the action of wind during vehicle driving.
