Detailed ways

As shown in Figure 1 and Figure 2, a kind of device for skylight, it comprises:

At least one guide rail 1, a stop component 7 arranged on the guide rail 1, the stop component 7 can be a single component, or the front beam of the sunroof;

A swing arm 2 that can lift and slide in the guide rail 1, the swing arm 2 has a first chute 3, a sliding pin 10 is arranged in the first chute 3, and a slider is arranged in the guide rail 1 4. The sliding pin 10 is arranged on a connecting plate 5, and the sliding block 4 and the connecting plate 5 are rotationally connected by a second sliding pin 23, and the first chute 3 has an arc shape in turn Upturning section 31, closing section 32, sinking section 33;

The swing arm 2 is provided with a first limiting block 21 and a second limiting block 22, and the guide rail 1 is at a position corresponding to the first limiting block 21, the second limiting block 22 and the second sliding pin 23 There are first opening 11, second opening 12 and third opening 13 respectively.

In use, the sunroof cover plate 9 can be fixed on the swing arm 2 through the feet 8 .

Further, as shown in FIG. 3 and FIG. 4 , at least one side of the slider 4 is provided with one or more first spring mechanisms 14 , and at least one second spring mechanism is provided on the upper or lower surface of the slider 4 mechanism 17, which can reduce the direct contact area between the slider 4 and the guide rail 1, reduce friction and reduce noise. Wherein, the first elastic mechanism 14 and the second elastic mechanism 17 and the slider 4 can also be integrally structured, and polyoxymethylene with excellent wear resistance and self-lubricating properties can be used for one-time injection molding.

Further, as shown in FIG. 3 , a rolling sleeve 15 is sheathed on the second sliding pin 23 , and the connecting plate 5 is fixedly connected with the rolling sleeve 15 . By rolling the rolling sleeve 15 around the second sliding pin 23, the sliding friction of the second sliding pin 23 can be transformed into rolling friction, thereby reducing the coefficient of friction. The material of the rolling sleeve 15 is polyoxymethylene.

Wherein, the connecting plate 5 is further provided with a third slide pin 24 on a side close to the swing arm 2 , and the swing arm 2 is provided with a second sliding slot 25 at a position corresponding to the third slide pin 24 . In this way, the stability between the connecting plate 5 and the swing arm 2 can be greatly improved through the arrangement of the first sliding groove 3 and the second sliding groove 25 .

Further, the second chute 25 sequentially includes a guiding sinking section 34 , a guiding closing section 35 and a guiding lifting section 36 .

Wherein, the front end of the swing arm 2 is provided with a sliding angle 6 , and the two sides of the rear end of the sliding angle 6 are provided with shrapnel 16 . When the sliding angle 6 slides in the guide rail 1 , friction can be reduced by means of the sliding angle 6 . When the second limit block 22 on the swing arm 2 reaches the tilting position of the sunroof, that is, when it reaches the second opening 12 of the guide rail 1, and the slider 4 continues to slide on the upturned section 31, the The elastic sheet 16 is folded downward, that is, the swing arm 2 is tilted upward, and the deformation and self-recovery of the elastic sheet 16 facilitates the tilting and closing of the skylight.

Wherein, the shrapnel 17 is a metal shrapnel, and the outside of the shrapnel 17 is coated with polyoxymethylene.

The groove wall 19 of the first chute 3 is coated with a layer of polyoxymethylene, which avoids the rigid collision of the limiting parts.

Wherein, the materials of the first limiting block 21 and the second limiting block 22 and the slider 4 are polyoxymethylene.

The following describes the operation process of the device for skylights of the present invention when the skylight is in the closed state, the raised state and the sunken state respectively.

1. Closed state

When the sunroof cover plate 9 and the roof are in the closed state, that is, when the first sliding pin 10 is in the closing section 32 of the first chute 3 and the third sliding pin 24 is in the guiding closing section 35 , The sliding angle 6 is in conflict with the stop member 7, at this time the swing arm 2 cannot move forward, and the first limit block 21 is stuck in the first opening 11 of the guide rail 1 and is in contact with it , the front end of the swing arm 2 cannot move backward; at the same time, the sliding pin 10, the slider 4 and the connecting plate 5 jointly fix the relative position of the rear end of the swing arm 2 and the guide rail 1, and the above state ensures that the sunroof The cover plate 9 and the roof have kept a relatively closed state.

2. Warped state

When the sunroof cover plate 9 is turned from the closed state to the raised state, the slider 4 moves forward, that is, the first slide pin 10 moves in the arc-shaped upturned section 31 of the first slide groove 3, and the The third sliding pin 24 moves in the guide warping section 36, and the connecting plate 5 is driven forward by the fourth sliding pin 15, and the connecting plate 5 moves forward in the chute 12 through the sliding pin 10, because the stopper part 7 and The sliding angle 6 is in conflict with each other, so the swing arm 2 can only move upwards. At this time, the first limiting block 21 moves upwards away from the first opening 11 of the guide rail, and the second limiting block 22 moves upwards to reach the second opening 12 of the guide rail at the same time. , and get stuck in it to realize the tilted state of the sunroof.

3. Sinking state

When the sunroof cover plate 9 is from the closed state to the sunken state, the slider 4 moves backward, that is, the first sliding pin 10 moves in the sinking section 33 of the first chute 3 , and the second The three sliding pins 24 move in the guide sinking section 34, and the fourth sliding pin 15 drives the sliding block 11 to move backward along the first chute 3, so that the sliding block 8 is still in the first opening 11 of the guide rail and is in contact with it. Contact, so the swing arm 2 can only move downwards. With the continuous downward movement of the swing arm 2, the first limit block 21 is separated from the first opening 11, and the second sliding pin 23 reaches the third opening 13. At this time , the third sliding pin 24 also moves in the second chute 25, and through the action of the third sliding pin 24 in the second chute 25, the connecting plate 5 is upturned, and the second sliding When the pin 23 reaches the third opening 13, it breaks away from the original track, and the connecting plate 5 rotates downward around the fourth sliding pin 15 to complete the sinking of the cover plate 9 . The slide block 4 continues to move backward along the guide rail 1, and then drives the swing arm 2 to move backward to a predetermined position through the connecting plate 5, thereby driving the sunroof cover plate 9 to move backward to complete the opening of the sunroof. The subsequent closing of the sunroof is opposite to the opening process of the sunroof, and a detailed description of the closing process is omitted here.

The above-described embodiments are only used to illustrate the technical ideas and characteristics of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. When the present invention cannot be limited only by this embodiment The patent scope of the present invention, that is, all equivalent changes or modifications made according to the spirit disclosed in the present invention still fall within the patent scope of the present invention.
