Description

Technical Field

[0001] The invention relates to the technical field of sunroof machinery, and in particular to a high-strength and high-toughness vehicle sunroof machinery assembly. Background Art

[0002] Car sunroofs are installed on the roof of the car, which can effectively circulate air in the car, increase the intake of fresh air, and bring health and comfort to the car owner; at the same time, car windows can also broaden the field of vision, and are often used for mobile photography and video shooting. Car sunroofs can be roughly divided into: sliding type, built-in type, built-in and flip-out type, panoramic type and curtain type.

[0003] The panoramic sunroof is actually different from the ordinary sunroof. Its advantages are wide field of vision and good ventilation. The panoramic sunroof is first of all larger in area, and can even be a whole piece of glass roof, so you can have a clear view of the scenery above when sitting in the car; currently most panoramic sunroofs are two separate pieces of glass in the front and back, so that the front and back seats can feel like a sunroof.

[0004] The invention with authorization announcement number CN205344478U is named a split-type mechanical group of a panoramic sunroof, which includes a glass fixing frame, a front driving frame and a rear driving frame. The front and rear driving frames are respectively driven by front and rear lifting arms to connect the glass fixing frame for lifting and lowering. The front and rear driving frames are connected by an "Ω"-shaped fixing head and an "Ω"-shaped groove in the front-to-back direction, which are plugged in and connected to each other perpendicularly to the front-to-back direction.

[0005] The mechanical group of the first structure drives the sliding wedge to slide on the second slide rail and the first slide rail on the lifting arm and the main sliding bracket through the driving unit, thereby realizing the control of the relative movement of the lifting arm and the main sliding bracket; and the driving unit can be used to pull the entire mechanical group, thereby realizing the pulling of the large panoramic sunroof glass loaded by the mechanical group. However, the mechanical group is an integrated structure, the mechanical group is relatively bulky, and the movement is not flexible enough, which affects the stable opening of the sunroof.

[0006] The second type of mechanical group has an "Ω"-shaped fixed head and an "Ω"-shaped groove in the front-to-back direction between the front and rear drive frames, which are plugged in and connected perpendicularly to the front-to-back direction. After plugging in, the front and rear drive frames are stably and tightly connected in the front-to-back direction to prevent them from moving forward and backward. The front and rear drive frames are connected through bosses and slots to prevent them from moving left and right. After connection, the overall anti-movement effect is good, stable, and firm, and it is not easy to deform during use. However, the structure of this mechanical group is relatively complex, and it is inconvenient to process and assemble. In addition, the connecting rod adopts a one-piece type and cannot be rotated. The firmness, stability, and rigidity of the connecting rod are difficult to guarantee. Summary of the invention

[0007] The present invention aims to overcome the deficiencies in the above-mentioned prior art, and its main purpose is to provide a high-strength and high-toughness vehicle sunroof mechanical group, which divides the connecting rod into sections and adopts a rotating structure through an articulated connection to improve the rotational strength of the connecting rod, which is beneficial to avoid the connecting rod from breaking during lifting, and significantly improves the firmness and stability of the connecting rod. The connecting rod is reinforced with ribs and hollowed out to be integrated, which greatly improves the strength and rigidity of the overall structure. The stability of the support arm and the connecting rod during lifting is achieved through buffer blocks and buffer pads, and vibration or noise during lifting is avoided. The strength and rigidity of the connecting rod and the rubber bag can be significantly improved by embedding non-Newtonian fluids, metal rubbers, and metal fibers inside the connecting rod and the rubber bag.

Fig.11It is a schematic diagram of the cross-sectional structure of the internal structure of the mechanical support plastic body of the high-strength and high-toughness vehicle sunroof mechanical group. When working, the sunroof glass installed on the high-strength and high-toughness vehicle sunroof mechanical group is supported by hand as a power source. At this time, the sunroof glass is pushed upward under the action of force, driving the support arm 1 to move upward. Since the front end of the support arm 1 is hingedly connected to the front lifting arm 3 through the front lifting arm connecting rivet 13, and the rear end is hingedly connected to the rear lifting arm 2 through the rear lifting arm connecting rivet 15, the upward movement of the support arm 1 will drive the rear lifting arm 2 and the front lifting arm 3 to rotate around the rear lifting arm connecting rivet 15 and the front lifting arm connecting rivet 13 respectively;

[0049] When the support arm 1 is vertically raised to the highest position without the rear link 5 and the front link 4 being moved, if the support arm 1 needs to be vertically raised, the front and rear link rotating heads 12 of the mechanical group at the middle connection between the rear link 5 and the front link 4 will rotate, driving the rear link 5 and the front link 4 to rotate around the front and rear link rotating heads 12 of the mechanical group, and the rear lifting arm 2 and the front lifting arm 3 will be adjusted accordingly to realize the vertical raising of the support arm 1;

[0050] The mechanical support plastic body 20 in the front link 4, the rear link 5, the front lifting arm rubber bag 6 and the rear lifting arm rubber bag 7 plays the most basic supporting role, and the metal rubber support mesh layer 21 and the organic fiber woven cloth layer 23 further strengthen the overall supporting effect, the magnetic non-Newtonian fluid medium layer 22, the plastic body reinforcement cavity 25 and the plastic body buffer cavity 26 effectively improve the impact resistance and shock absorption and buffering effects of the front link 4, the rear link 5, the front lifting arm rubber bag 6 and the rear lifting arm rubber bag 7, and the fiber wear-resistant protective film layer 24 significantly improves the wear resistance of the surface of the front link 4, the rear link 5, the front lifting arm rubber bag 6 and the rear lifting arm rubber bag 7.
