Description

Technical Field

[0001] The utility model relates to a skylight structure, in particular to a lifting skylight mechanical group. Background Art

[0002] Today, with the increasing performance requirements of automotive skylights, in the existing lifting open skylight structure, the electric cylinder pushing the skylight to lift and open has the following problems: it requires a large vertical space and occupies the height space inside the vehicle; moreover, when the electric cylinder bears weight for a long time, it is prone to failure or malfunction retraction, and the skylight is likely to open when closing, resulting in unstable skylight opening performance. Summary of the Invention

[0003] The utility model provides a multi-link stable lifting skylight mechanical group with a simple structure, stable opening support and closing locking.

[0004] The technical solution adopted by the utility model is: a multi-link stable lifting skylight mechanical group, including a lifting arm connected to the lower end of the non-hinged vehicle body side of the skylight glass body, characterized in that: it further includes more than two lifting groups, and more than two lifting groups are arranged in the slide rail of the guide rail along the front-back direction of the skylight side guide rail for guiding and limiting sliding. The lifting group includes a driving block, a main lifting arm, a passive lifting arm and a lifting link. The driving block is arranged in the slide rail, the lower end of the main lifting arm is hinged to the driving block, the upper end of the main lifting arm, the upper end of the passive lifting arm and the lower end of the lifting link are hinged with the same pin shaft. The lower end of the passive lifting arm is hinged to the guide rail, and the upper end of the lifting link is hinged to the lifting arm. The driving block of any one or more lifting groups is connected to the lifting driving structure and is in a driven sliding state in the slide rail. A rearward clamping interface is arranged on the driving block of any one lifting group, and a clamping joint for closing and clamping into the clamping interface is arranged at the corresponding position behind the lifting arm.

[0005] The lifting driving structure is a driving rack, the driving rack is connected to the driving block, and the driving rack is driven by a driving motor through gear meshing.

[0006] The lifting driving structure is a screw rod, the screw rod is connected to the driving motor, and the screw rod is threadedly connected to the driving block.

[0007] The lifting links of other lifting groups outside any one lifting group are correspondingly hinged to the lifting arm in the lifting through groove along the front-back direction on the lifting arm.

[0008] The beneficial effects of the utility model are as follows:

[0009] 1. The lifting group drives the driving block through the lifting driving structure, and the driving block actively drives the main lifting arm. Under the constraint of the multi-link structure of the main lifting arm, the passive lifting arm and the lifting link, the upper end of the lifting link drives the lifting arm to lift, and multiple lifting groups are combined to synchronously lift the lifting arm to ensure stable support after lifting.

[0010] 2. The lifting drive mechanism uses a drive rack or a screw rod to drive a drive block to slide along a guide rail, without occupying height space.

[0011] 3. A clamping joint is provided on the lifting arm. When the lifting arm closes with the lifting group, it is directly clamped into the clamping interface on the drive block corresponding to the position of the clamping joint, realizing stable locking of the skylight when it is closed.
