[0056] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0057] In the following text, the terms front, back, up, and down refer to Figure 1 The first side of all components refers to Figure 1 The second side of all components refers to the side where the arrow S1 is located. Figure 1 The side where the arrow S2 is located. One of the first side and the second side is the inner side, and the other side is the outer side.

[0058] See also Figures 1 to 8The sunroof movement mechanism provided in the embodiment of the present application includes a guide rail 1, a main swing arm 2, a rear flip device 3, a connecting rod device 4, a locking member 5, a force member 6 and a main slider 7. The front end of the main swing arm 2 is slidably connected to the slide groove 11 of the guide rail 1, and the main slider 7 is slidably connected to the front end of the main swing arm 2. The rear flip device 3 is rotationally connected to the guide rail 1 and slidably connected to the rear end of the main swing arm 2. The main slider 7 can slide in the slide groove 11 of the guide rail 1 under the drive of the driving device, thereby driving the main swing arm 2 to move.

[0059] See also Figure 5 and Fig.14 The connecting rod device 4 includes a front sliding member 41, a rear sliding member 42 and a steel wire flexible shaft 43 connected between the front sliding member 41 and the rear sliding member 42. The front sliding member 41 and the rear sliding member 42 are slidably arranged in the slide groove 11 of the guide rail 1. The rear sliding member 42 is slidably connected to the rear flipping device 3. The locking member 5 is rotatably connected to the front sliding member 41. A locking hole 12 is provided at the bottom of the guide rail 1. A downwardly protruding buckle 51 is provided at the bottom of the locking member 5. The force of the force-applying member 6 acts on the locking member 5, so that the locking member 5 has a tendency to rotate downward; a locking slider 71 is provided on the main slider 7, and a locking slide groove 52 is provided on the locking member 5.

[0060] The main swing arm 2 can be in a first position corresponding to the sunroof closed state (see Fig.10 ) to the tilted position corresponding to the tilted state of the sunroof (see Fig.11 ), and moves from the tilted position to the second position corresponding to the sunroof opening state (see Fig.12 ).

[0061] During the movement of the main swing arm 2 from the first position to the tilting position, the locking slider 71 is combined with the locking slot 52, the main slider 7 is linked with the locking member 5, and then the main slider 7 drives the rear flipping device 3 to be linked and flipped through the connecting rod device 4; when the locking member 5 moves to the locking hole 12, the buckle 51 of the locking member 5 rotates and snaps into the locking hole 12 under the force of the force-applying member 6, locking the connecting rod device 4 on the guide rail 1, and when the main swing arm 2 reaches the maximum tilting position, the locking slider 71 escapes from the locking slot 52, and the locking member 5 and the connecting rod device 4 are separated from the main slider 7; thereafter, the main swing arm 2 continues to move to the second position (the locking member 5 and the connecting rod device 4 do not move), so that the sunroof is opened and stops until it is fully opened. The whole process from closing to opening of the sunroof is realized.

[0062] Specifically, in the process of the main swing arm 2 moving from the first position to the tilting position, the locking slider 71 is combined with the locking slide groove 52, the main slider 7 drives the locking member 5 and the front sliding member 41 to work together, the front sliding member 41 pulls the steel wire flexible shaft 43, the steel wire flexible shaft 43 pulls the rear sliding member 42, and the rear sliding member 42 drives the rear flipping device 3 to work together and flip.

[0063] Conversely, when the sunroof moves from opening to closing, the locking slider 71 of the main slider 7 moves along the slide groove 11 of the guide rail. When it moves to the locking slider 71 and re-combines with the locking slide groove 52 of the locking member 5, since the locking slide groove 52 has a downward slanting trajectory, the locking slide groove 52 of the locking member 5 is squeezed by the movement of the locking slider 71 of the main slider 7 to generate an upward turning force around its rotation axis. The buckle 51 of the locking member 5, driven by the locking slider 7 of the main slider 7, overcomes the force of the force-applying member 6 and escapes from the locking hole 12, completing the unlocking. Afterwards, the connecting rod device 4, the locking member 5 and the main slider 7 are re-linked, and the sunroof returns to the closed state.

[0064] The locking member 5 is rotatably connected to the front sliding member 41 via a rivet (serving as a rotating shaft).

[0065] In one embodiment, see Figure 7 and Figure 8 The main swing arm 2 includes a slide rail portion 21 and a slide groove portion 22 connected to the front end of the slide rail portion 21, and the main swing arm slide grooves are arranged on the inner and outer sides of the slide groove portion 22.

Through the sliding between the main swing arm slot of the slot portion 22 and the sliding block of the main slider 7, and the sliding between the slide rail portion 21 and the rear support member 31, the main slider 7 and the rear support member 31 can slide smoothly on the main swing arm 2 without falling off.

[0078] In one embodiment, the rail portion 21 is a metal-coated plastic structure, and the rear support member 31 is a metal-coated plastic structure. A metal-coated plastic structure refers to a structure formed by coating a metal part with plastic. In this way, the sliding between the rail portion 21 and the rear support member 31 is a friction contact between plastics, which is beneficial to reduce the friction resistance when the main swing arm 2 moves, improve the durability of the main swing arm 2 and the rear support member 31, and thus increase the service life of the sunroof. In addition, the friction noise when the sunroof moves can be reduced.

[0079] In one embodiment, the rear sliding member 42 is located on the side of the second connecting rod 33 away from the first connecting rod 32, and a protrusion 421 is provided on the rear sliding member 42. The protrusion 421 is provided with a first rear sliding member slot 42a and a second rear sliding member slot 42b. The first rear sliding member slot 42a is located behind the second rear sliding member slot 42b. The upper end of the first rear sliding member slot 42a is closed and the lower end is open, and the upper end of the second rear sliding member slot 42b is open and the lower end is closed. Figure 5 The second connecting rod 33 is provided with a first positioning pin 331 and a second positioning pin 332, the first positioning pin 331 is slidably connected in the first rear sliding member slot 42a, and the second positioning pin 332 is slidably connected in the second rear sliding member slot 42b; when the main swing arm 2 reaches the maximum tilting position, the first positioning pin 331 abuts against the upper end wall of the first rear sliding member slot 42a, and the second positioning pin 332 escapes from the upper end opening of the second rear sliding member slot 42b.

[0080] In one embodiment, the fixed base 10 is a plastic part, and when the main swing arm 2 is in the second position, the rear end surface of the main slider 7 abuts against the fixed base 10. In this way, the maximum backward sliding stroke of the main slider 7 can be limited, that is, the maximum backward stroke of the main swing arm 2 is limited, and the maximum opening position (full opening) of the sunroof is limited.

[0081] In one embodiment, see Figure 1 The sunroof movement mechanism also includes a first slide plate and a second slide plate, the first slide plate 20 is provided with a first slide groove, the second slide plate 30 is provided with a second slide groove, the first slide plate 20 and the second slide plate 30 are fixed in the slide groove 11 of the guide rail 1 by buckles or screws, and the first slider 24 and the second slider 25 are respectively provided on both sides of the front end of the main swing arm 2, the first slider 24 is slidably connected in the first slide groove, and the second slider 25 is slidably connected in the second slide groove.

[0082] In one embodiment, the first slide plate 20 and the second slide plate 30 are plastic parts; when the main swing arm 2 is in the first position, the front end surface of the main slider 7 abuts against the first slide plate 20 and the second slide plate 30. In this way, the maximum forward sliding stroke of the main slider 7 can be limited, that is, the maximum forward stroke of the main swing arm 2 is limited, and the closing position of the sunroof is limited.

[0083] When the main swing arm 2 moves from the first position to the tilting position, the first slider 24 is located in the first slide groove, and the second slider 25 is located in the second slide groove. Afterwards, the first slider 24 escapes from the first slide groove, and the second slider 25 escapes from the second slide groove, and the slide groove portion 22 continues to slide along the guide rail 1.

[0084] When designing the sunroof, the shapes of the various slide grooves in the above-mentioned embodiment can be simulated according to the movement trajectory of the sunroof glass (main swing arm 2).

[0085] According to the sunroof movement mechanism of the embodiment of the present application, during the movement of the main swing arm from the first position to the tilting position, the locking slider of the main slider is combined with the locking slide groove of the locking member, the main slider and the locking member are linked, and then the main slider drives the rear flip device to be linked and flipped through the connecting rod device; when the locking member moves to the locking hole of the guide rail, the buckle of the locking member rotates and snaps into the locking hole under the force of the force-applying member, locking the connecting rod device on the guide rail. At this time, the main swing arm reaches the maximum tilting position, and the locking slider is separated from the locking slide groove; then, the main swing arm continues to move to the second position. In this way, the main swing arm reaches the second position from the first position via the tilting position, and correspondingly, the sunroof reaches the open state from the closed state via the tilting state. Compared with the existing method of locking and unlocking by driving the rotary valve when the main slider slides, the cooperation between the buckle of the locking member and the locking hole of the guide rail makes the locking more stable and less likely to fail.

[0086] In addition, the connecting rod device can be integrated with the locking device (locking piece), which has the advantages of simple structure, reduced number of parts, stable structure, and low cost. The sunroof using this connecting rod device has stable opening and closing of the sunroof glass, giving customers a good driving experience.

[0087] In addition, in another embodiment not shown in the figure, the first slider and the second slider can be replaced by a cylindrical rotatable rivet slider, and the first slide plate and the second slide plate can be eliminated. This structure is easy to process, has low sliding resistance in the guide rail, and can keep the cross section of the guide rail unchanged, so that the whole process from opening to closing can be completed in the slide rail slide groove, without the need to add other external devices, reducing the first slide plate and the second slide plate, and reducing costs.

[0088] In another embodiment not shown in the figures, the leaf spring may be replaced by a torsion spring or a compression spring.

[0089] In another embodiment not shown in the figure, at least one of the first sliding block, the second sliding block and the third sliding block of the main slider is replaced with a cylindrical rivet-type slider. This structure can reduce the resistance between the main slider and the main swing arm, so that the movement resistance of the sunroof movement mechanism is reduced, the movement is smoother, and the main slider is easy to process.

[0090] On the other hand, see Fig.15 The embodiment of the present application also provides a sunroof, including a driving device, a sunroof glass 100 and the above-mentioned sunroof motion mechanism, wherein the sunroof motion mechanism is arranged on the left and right sides of the sunroof opening of the roof 200, and the sunroof glass 100 is installed on the main swing arms of the sunroof motion mechanism on the left and right sides, and the driving device is used to drive the main slider of the main swing arm of the sunroof motion mechanism to move.
