Problems solved by technology
[0004] The operation of the transmission chain 4 needs pipe fittings matching its diameter. In the prior art, multiple metal pipe fittings are usually fixed on the front beam 1 to realize the operation of the transmission chain 4. This solution requires multiple metal pipe fittings. Multiple assembly parts are required to fix these metal pipe fittings, and it is difficult to meet the design requirements of minimizing the number of parts and minimizing the cost

Embodiment Construction
[0020] Such as figure 2 As shown, a sunroof front beam 1 is provided with two transmission chain 4 passages consisting of a plurality of upper covers 12 and a plurality of lower covers 11, and the upper covers 12 and the lower covers 11 alternately It is provided that the front beam 1 of the sunroof is integrated with the upper cover 12 and the lower cover 11 . The upper cover 12 and the lower cover 11 can be injection-molded together with the front beam 1 of the sunroof through a drafting process, and a certain number of lower covers 11 can be provided at intervals of a certain number of upper covers 12 in a way that the structures are alternately arranged.
[0021] A preferred manner is that the upper covers 12 and the lower covers 11 are arranged alternately one by one.
[0022] Wherein, the transmission chain passage is arranged on the outer side of the front beam 1 of the sunroof.
[0023] Wherein, the side of the upper cover 12 close to the transmission chain 4 is a s...

The invention relates to a skylight front cross member. Two driving chain passages comprising a plurality of upper covers and a plurality of lower covers are arranged on the skylight front cross member; the upper covers and the lower covers are alternately arranged; and the skylight front cross member, the upper covers and the lower covers are integrated. Further, the upper covers and the lower covers are alternately arranged in sequence; one side of each upper cover close to the driving chain has a smooth lug boss structure; one side of each lower cover close to the driving chain has a smooth lug boss structure; the cross section of the upper cover is semicircular; and the cross section of the lower cover is semicircular. The invention approximately realizes a hollow tube structure through the alternately arranged upper covers and the lower covers of an opening structure. The only requirement to process the skylight front cross member is adopting a die with an up and down alternate pattern lifting structure, thereby effectively reducing metal pipes and a processing technique thereof as well as manufacture cost.
Description
technical field [0001] The invention belongs to the technical field of automobile skylights, in particular to a front beam of an automobile skylight. Background technique [0002] Such as figure 1 As shown, the car sunroof includes main components such as moving parts, fixed support parts, transmission parts and driving devices. The moving parts mainly include a glass panel 5 and a mechanical group 6 . The fixed supporting parts mainly include components such as the front beam 1, the side guide rail 2, and the middle beam 7. The transmission part is mainly the transmission chain 4; the driving device is mainly the motor 3, wherein the front beam 1 is usually made of plastic through injection molding. [0003] Its operating principle is that the motor 3 outputs power, and the power is transmitted to the mechanical group 6 through the transmission chain 4. The glass panel 5 is fixed on the mechanical group 6, so that the ultimate goal of glass operation can be achieved. ...
