Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile sunroof technology, and particularly relates to a panoramic sunroof type automobile sunroof guide rail. BACKGROUND

[0002] In order to visually increase the space in the vehicle, the panoramic sunroof scheme is selected in the existing vehicle. This scheme has a disadvantage that it is difficult to set an openable sunroof structure on the roof. If the sunroof is designed to be small, the guide rail mechanism needs to be set on the glass body, which destroys the overall aesthetics, and the safety of the glass supported guide rail structure is not high. If the sunroof is designed to be large, although the guide rail mechanism can be designed on the metal structure near the edge of the roof, the sunroof is slid out of the back of the vehicle in the existing technical scheme. A large area of sunroof undoubtedly significantly increases the wind resistance of the vehicle during driving, and also puts greater test on the strength and stability of the guide rail structure. SUMMARY

[0003] The purpose of the present application is to provide a sunroof guide rail that can enable a large area of movable sunroof to be opened in the roof by sliding inward.

[0028] As Figures 1-8 The panoramic sunroof type automobile sunroof guide rail shown in the drawings has a guide rail body 5, which has a front section guide rail 510 and a rear section guide rail 520 with the same structure. The front section guide rail 510 and the rear section guide rail 520 both have a smooth section 503, the front end of the smooth section 503 is connected with a lifting section 505 through a slanted sliding section 504, the smooth section 503, the slanted sliding section 504 and the lifting section 505 are integrated, and the smooth section 503 and the lifting section 505 of the front section guide rail 510 and the rear section guide rail 520 are in the same direction. The slanted sliding section 504 of the front section guide rail 510 and the rear section guide rail 520 is parallel to each other, although not in the same direction. The bottom surface of the smooth section 503, the slanted sliding section 504 and the lifting section 505 of the front section guide rail 510 has an integrated bottom support section 506, and the bottom surface of the smooth section 503, the slanted sliding section 504 and the lifting section 505 of the rear section guide rail 520 also has an integrated bottom support section 506. The extension direction of the bottom support section 506 is consistent with the smooth section 503, the slanted sliding section 504 and the lifting section 505, which first extends in a straight direction, then tilts forward, and then returns to the straight direction.

[0029] The front section guide rail 510 and the rear section guide rail 520 both have a lead wire channel 501 extending from the front end of the lifting section 505 through the inside of the slanted sliding section 504 to the rear end of the smooth section 503, which is the main space where the traction steel wire of the movable sunroof is located or moves. The front section guide rail 510 and the rear section guide rail 520 both have a continuous traction sliding groove 502 on the outer side of the smooth section 503, the slanted sliding section 504 and the lifting section 505, which communicates with the lead wire channel 501. The traction steel wire passes through the traction sliding groove 502 to connect with the sliding foot of the movable sunroof. The rear end of the smooth section 503 of the front section guide rail 510 and the front end of the lifting section 505 of the rear section guide rail 520 are fixedly connected with a bridging plate 4, which is used to fixedly connect the front end of the lower rear section guide rail 510 with the front end of the higher rear section guide rail 520. In order to ensure that the traction steel wire in the rear section guide rail 520 can move synchronously with the steel wire in the front section guide rail 510, the bridging plate 4 is also provided with a communication channel 401 that communicates the lead wire channels 501 in the front section guide rail 510 and the rear section guide rail 520, through which the traction steel wire mainly located in the rear section guide rail 520 slides.

[0030] The two guide rail bodies 5 need to be arranged symmetrically and parallel to each other on the roof of the vehicle, and the two front section guide rails 510 are fixedly connected with the front beam 1 at the front ends of the lifting portions 505 of the two front section guide rails 510. The front beam 1 is further provided with connecting holes 101 at both ends of the front beam 1, so that bolts or other connecting members can pass through the connecting holes 101 to be fixedly connected with the roof frame. The lifting portions 505 of the two front section guide rails 510 are fixedly connected with the front beam 1 through the limiting plates 3. The front lead holes 302 are formed in the front surface of the limiting plate 3 and are in communication with the lead channels 501, so that the steel wires can be pulled into or pulled out of the guide rail bodies 5. The limiting plate 3 is further provided with the positioning holes 301 on the side surface opposite to the front beam 1. The positioning holes 301 can be used for pre-positioning when the sunroof guide rails are installed, so that the installation precision and efficiency can be improved. The height of the end portion of the front beam 1 is located between the positioning holes 301 and the front lead holes 302, so that the installation and positioning are not affected, and the movement of the steel wires is not affected. The rear ends of the smooth portions 503 of the two rear section guide rails 520 are fixedly connected with the rear beam 2. The front beam 1 and the rear beam 2 jointly maintain the stability of the distance between the two guide rail bodies 5. The rear beam 2 is further provided with the rear lead holes 202 at both ends of the rear beam 2, which are in communication with the lead channels 501 and are also used for pulling the steel wires into or out of the guide rail bodies 5. The rear beam 2 is further provided with the connecting plate 201 at the middle portion of the rear beam 2, which is also used for being fixedly connected with the roof frame.
