Referring to FIGS. 1 through 3, a preferred embodiment of the present invention provides a low-resistance sunroof actuating mechanism that is disposed on a roof of an automobile and that is configured to move a glass panel of a sunroof of the vehicle corresponding to a window on the roof ( Not shown in the figure). Preferably, the two sides of the glass plate are respectively provided with a set of low-resistance automobile sunroof actuating mechanisms, and the configuration of the pair of low-resistance sunroof actuating mechanisms may be the same or phase mirroring. In the present embodiment, the low-resistance sunroof actuating mechanism of the present invention includes a slide rail 100, a slider 200, a traction block 300, and a linkage assembly 400.

In the embodiment, the slide rail 100 is a metal strip body, and the slide rail 100 defines a sliding slot 101. The sliding slot 101 extends along the longitudinal direction of the slide rail 100. The shape of the slide rail 100 is made according to the curvature of the roof. Therefore, the chute 101 is a curved groove. In general, the rails 100 are disposed outside the opposite sides of the window of the roof and the rails 100 extend beyond the length of the corresponding side of the window. A wire slot 102 extending parallel to the sliding slot 101 is defined in the sliding slot 101. The inner side of the sliding rail 100 is further provided with a pair of side slots 103 disposed opposite to each other, and the side slots 103 extend in the longitudinal direction of the sliding slot 101. A guide block 110 is disposed at one end of the chute 101, and a channel (not shown) connecting the chute 101 is disposed in the front guide block 110.

Referring to FIG. 2 to FIG. 5 , in the embodiment, the slider 200 is an elongated plastic block. One end of the slider 200 extends a hinge 210 and the slider 200 extends laterally from the pair of ribs 220 . The slider 200 is received in the sliding slot 101. The pair of ribs 220 respectively penetrate into the side slots 103, and the slider 200 and the bottom of the sliding slot 101 are spaced apart from each other. A sliding groove 201 is defined in the sliding block 200. The steering groove 201 extends in the longitudinal direction of the sliding block 200 and the two ends of the steering groove 201 have different inclination angles. The rib 220 has a diamond-shaped cross-section to allow the rib 220 to be deflected within the side groove 103, thereby allowing the slider 200 to deflect within the chute 101 to facilitate passage through the chute 101.

In the present embodiment, the traction block 300 is a plastic block, the traction block 300 has a traction shaft 310 and the traction block 300 extends laterally from the pair of wings 320. The traction block 300 is received in the sliding slot 101. The pair of wings 320 are respectively inserted into the side slots 103, and the traction block 300 and the bottom of the sliding slot 101 are spaced apart from each other. The traction shaft 310 is pivotally connected to the end of the hinge 210. One end of one of the wings 320 is formed with a sliding post 330. The sliding post 330 is connected with a pull wire 301. Preferably, one end of the pull wire 301 is embedded in the sliding post 330. The spool 330 is disposed in the cable slot 102, and the cable 301 is disposed in the cable slot 102. The pull wire 301 is connected to a driving component (not shown, which may be a motor or a worm and a worm gear that meshes with the motor) and can be driven by the driving component to slide in the cable slot 102, wherein the cable 301 is As a result, the pulling block 300 can be pushed and pulled by the reciprocating action of the wire 301.

The slider 200 can also be directly connected to the pull wire 301 without configuring the traction block 300. In the present embodiment, the reason why the pull wire 301 is connected to the traction block 300 instead of the slider 200 is that the traction block 300 has a small volume and is easy to be steered in the sliding slot 101, and the pulling force of the pulling wire 301 to the traction block 300 can be The movement in the direction of movement of the traction block 300 is maintained, thus avoiding the generation of lateral component forces to reduce the friction of the traction block 300 with the inner wall of the chute 101.

The traction block 300 and the slider 200 are connected by a hinge 210, so the traction block 300 must be moved a long distance to drive the slider 200 to rotate a small amount, thereby preventing the slider 200 from rotating sharply to generate a lateral component.

In the present embodiment, the link assembly 400 includes a main link 410 and a pair of links 420 for carrying the glass plate. The two ends of the main link 410 are respectively a front end 411 and a rear end 412. A front end 411 of the main connecting rod 410 protrudes from a sliding shaft 413. The front end 411 of the main connecting rod 410 is received in the sliding slot 101 and the sliding shaft 413 It penetrates into the side groove 103 and is movable along the side groove 103, whereby the front end 411 of the main link 410 can be moved along the chute 101. One end of the secondary link 420 is pivotally coupled to the rear end 412 of the primary link 410. A support shaft 421 is protruded from a middle portion of the auxiliary link 420, and a steering shaft 422 is protruded from the other end of the auxiliary link 420. In the embodiment, the support shaft 421 is respectively protruded toward the lateral sides of the auxiliary link 420, and is turned. The shaft 422 also protrudes toward the lateral sides of the sub-link 420, respectively. The support shaft 421 and the steering shaft 422 respectively penetrate the steering groove 201 and are movable along the steering groove 201.

Referring to FIG. 1 and FIG. 2, in the low-resistance sunroof actuating mechanism of the present invention, when the link assembly 400 is folded, the sliding shaft 413 of the front end 411 of the main link 410 is received in the front guide block 110, and the main link 410 and the pair The link 420 is folded and folded, and the support shaft 421 and the steering shaft 422 are located at one end of the steering groove 201, so that the main link 410 is fitted to the opening of the chute 101. When the main link 410 and the sub-link 420 are folded and folded, the glass plate carried on the main link 410 is attached to the roof and closes the window.

Referring to FIG. 6, the traction block 300 is moved in the foregoing manner to drive the slider 200 to move in the sliding slot 101. When the slider 200 moves, the support shaft 421 and the steering shaft 422 are moved to the other end of the steering groove 201, and the inclination is changed. (The inclination angles of the two ends of the steering groove 201 are different) such that the steering shaft 422 relatively rotates around the support shaft 421 to drive the sub-link 420 to rotate. The rear end 412 of the main link 410 is lifted off the slide rail 100 by a rotating secondary link 420. When the traction block 300 continues to pull the slider 200 toward the other end of the chute 101, the sliding shaft 413 The front block 110 is pulled out into the side groove 103, whereby the front end 411 of the main link 410 is lifted off the slide rail 100. The traction block 300 continues to pull the slider 200 toward the other end of the chute 101, and the slide shaft 413 simultaneously moves toward the other end of the chute 101 along the side groove 103. Thus the glass sheet carried on the main link 410 completely leaves the slide rail 100, which can continue to be pulled by the traction block 300 toward the other end of the chute 101 away from the window.

Referring to FIGS. 2 to 5, when the slider 200 slides within the slide rail 100, the slider 200 is suspended by the rib 220 and the flap 320 within the chute 101, between the slider 200 and the chute 101. The source of the frictional resistance is limited to the rib 220 and the flap 320, and the frictional resistance between the slider 200 and the chute 101 is extremely small, so that the slider 200 can smoothly pass through the chute 101.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the invention, and other equivalent variations of the patent spirit of the present invention are all within the scope of the invention.
