[0002] At present, with the continuous development of automobile sunroof technology, panoramic sunroofs are becoming more and more mainstream in the automobile market. Since panoramic sunroofs can provide users with a larger visual space experience, there are higher requirements for the motion device technology of panoramic sunroofs. The existing motion device structure in this field includes: a front support device, a drive device, and a rear support device. Since the front support device of the existing technology cannot lift the front glass assembly to a safe distance (>5mm) from the upper surface of the rear glass, the front glass cannot be fully moved above the rear glass, and even after it is fully opened, the front ear of the front glass is prone to scratching the upper surface of the rear glass. Therefore, the opening stroke of the front glass of the panoramic sunroof in the existing technology is limited, and the need for a visual opening of the panoramic sunroof cannot be met. It also limits the advancement of the platformization of the enterprise's motion device and the breadth of matching types. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] This utility model provides a sunroof mechanism assembly specifically designed for use with a small panoramic sunroof. The small panoramic sunroof is formed by two panes of glass: one movable and the other fixed. When the sunroof is closed, the movable and fixed panes do not overlap at all; they lie side by side to cover the vehicle's sunroof area.

[0031] like Figures 1-12 As shown, the utility model provides a sunroof mechanical group, which includes a first supporting device, a second supporting device that jointly supports a movable sunroof glass with the first supporting device, and a driving device connected to the second supporting device. Under the action of external force, the first supporting device, the second supporting device and the driving device work in conjunction to switch the panoramic sunroof between an open state and a closed state.

[0032] Schematically, as Figure 2As shown, both the first support device and the second support device are connected to two ends of the same movable sunroof glass. For example, the first support device is fixedly connected to the front end of the movable sunroof glass, and the second support device is fixedly connected to the rear end of the movable sunroof glass. The second support device is movably connected to the driving device. Schematically, when the sunroof switches from the closed state to the open state, its working process is as follows: an external force applies a pulling force in the direction of the rear of the vehicle to the driving device, causing the driving device to displace in the direction of the rear of the vehicle. During the displacement of the driving device, the second support device is driven to move. During the movement of the second support device, it first drives one end of the movable sunroof glass to move in the vertical direction (i.e., the end of the movable sunroof connected to the second support device warps), and at the same time, the first support device moves passively (since the first support device is rigidly connected to the movable sunroof glass, the movable sunroof glass drives the first support device to move along the Y-axis direction so that the other end of the movable sunroof warps). After the movable sunroof is bent, warped, and lifted, it continues to move along the X-axis direction, thereby realizing the opening of the movable sunroof glass. Applying an external force in the opposite direction to the driving device can realize the closing of the sunroof.

[0033] In the above technical solution, through the first support device, the second support device that jointly supports the movable sunroof glass with the first support device, and the driving device connected to the second support device, the first support device, the first support device, and the driving device cooperate with each other to realize the opening and closing of the sunroof. The structure is relatively simple. There is no direct connection between the first support device, the second support device, and the driving device, and the installation is relatively simple. The installation process requirements are simple. In addition, due to the simple structure, its overall compatibility is relatively strong, and it can be applied to the installation and use of various vehicles.

[0034] As a further preferred implementation, the above-mentioned sunroof mechanical group, such as Figure 3 , 4 As shown in Figure 5, the first support device 1 includes a first connecting rod 121. One end of the first connecting rod 121 is provided with a first connector 122 for connecting the movable sunroof glass, and the other end of the first connecting rod 121 is provided with a movable support member 132. Under the action of an external force, the first connecting rod 121 performs a displacement movement in the vertical direction with the movable support member 132 as the fulcrum. It should be noted that the external force in this embodiment is not directly applied to the first connecting rod 121. The external force is applied to the driving device 3, the driving device 3 drives the second support device 2, and the second support device 2 transmits this external force to the first connecting rod 121 through the movable glass.

[0035] As a further preferred embodiment, a pin hole is provided at the end of the first support device to match and connect the first connector and the pin of the end of the first support device, so that the front end of the first connector rotates around the pin hole at the end of the first support device; the skylight glass is fixed to the first connector by bolts; a limiting structure is provided at the tail end of the first connector. When the mechanical group is closed, the limiting structure member is snapped into the front slot of the driving device, thereby fixing the first connector.

[0036] A sliding limiting device 141 matching the first sliding groove is further provided between the first connector 122 and the movable support member 132. During the displacement of the first connecting rod 121, the sliding limiting device 141 is displaced within the first sliding groove to limit the displacement of the first connecting rod in the Y-axis direction. Further, the sliding limiting device 141 is integrally formed with the first connecting rod 121, or a detachable sliding foot structure is used to snap into the first connecting rod 121 to form the sliding limiting device; for example, a detachable sliding foot structure sleeved with an elastic structure is inserted into the first connecting rod 121 to form the sliding limiting device 141, and the sliding limiting device 141 is disposed inside the first sliding groove 61. It should be noted that the first sliding groove 61 is provided inside the guide rail 6. The first sliding groove 61 can be provided inside the guide rails at the edges of existing vehicle windows, and the present invention does not introduce the first sliding groove in detail. In the present invention, the guide rail and the first sliding groove only serve as mating parts for the skylight mechanical group to work.

[0037] In the above technical solution, the free end of the sliding limiting device 141 is disposed inside the first sliding groove 61 of the guide rail 6, aiming to reduce the displacement in the Y-axis direction (that is, to reduce the sway of the first connecting rod in the Y-axis direction during movement).

[0038] Further, the sliding limiting device 141 is formed by elastic plastic coating. The elastic plastic coating itself has a certain elasticity. When the elastic plastic-coated sliding limiting device 141 is disposed inside the first sliding groove 61, the elastic plastic structure matches the first sliding groove 61. The elastic plastic coating aims to absorb the gaps in the Y-axis direction and the X-axis direction, and further improve the smoothness of the first connecting rod 121 during movement.

[0039] As a further preferred implementation, for the above-mentioned skylight mechanical group, a fulcrum connection hole 130 is opened at the end of the first connecting rod 121 that matches the movable support member 132. The movable support member 132 includes a pin shaft 131 inserted into the fulcrum connection hole 130 and support sliding feet 132 fixedly connected to both ends of the pin shaft 131 and matching a guide rail chute 63. Among them, the rotation center of the pin shaft 131 is the same as the center line of the support sliding feet 132. The support sliding feet 132 can be installed by an assembly method, saving the cost of the rubber coating mold for the support sliding feet 132 and also reducing the maintenance cost of the first support device. In addition, it also increases the opening height of the movable skylight glass.

[0040] As a further preferred implementation, for the above-mentioned skylight mechanical group, as Figure 7 shown, the second support device 2 includes a second connecting rod 21. One end of the second connecting rod 21 is provided with a second connector 22 for connecting the movable skylight glass. A driving protrusion is provided on the second connecting rod 21. Under the action of an external force (i.e., the motion state of the driving device 3), the driving protrusion of the second connecting rod 21 displaces along the track groove 31 to achieve the vertical movement of the second connecting rod 21. Further, the driving protrusion includes a first driving block 24 and a second driving block 23. The first driving block 24 is provided at one end of the second connecting rod away from the second connector 22, and the second driving block 23 is provided in the middle area of the second connecting rod 22 and close to the first driving block 24. Under the motion state of the driving device 3, the first driving block 24 and the second driving block 23 displace along the track groove 31 to achieve the vertical movement of the second connecting rod 21.

[0041] Further, the driving device 3 includes a track groove 31 that matches the driving protrusion. Further, the driving device 3 also includes a driving sliding foot 32. The driving sliding foot 32 matches the support sliding foot 132. In actual application, the driving sliding foot 32 and the support sliding foot 132 are both located in the guide rail chute 63.

[0042] As a further preferred embodiment, in the above technical solution, the second support device further includes a locking protrusion that matches the locking device. In the state where the second support device is not lifted, the locking protrusion is located within the locking device, that is, one end of the second support device is locked by the locking device. In the state where the second support device is lifted, a force is continuously applied to the second support device. When the applied force is greater than the locking pressure of the locking device, the locking protrusion disengages from the second support device, and at this time, the X-axis direction of the second support device is unlocked. Before this, due to the action of the locking device, the second support device can only move in the Y-axis direction, and the X-axis direction is restricted.

[0043] Schematically, the linkage cooperation relationship between the second support device and the driving device is as follows: when the skylight switches from the closed state to the open state, an external force drives the driving device to displace towards the tail direction of the automotive skylight.

[0044] When the skylight switches from the closed state to the open state, an external force drives the driving device to displace towards the tail direction of the automotive skylight, the driving sliding foot moves towards the tail direction of the automotive skylight within the guide rail chute, and the driving protrusion moves passively along the track groove. Applying a reverse force to the driving device can realize the switching of the movable skylight glass from the open state to the closed state.

[0045] As Figure 7 shown, the detailed process of this movement process is as follows (the arrow is the movement direction);

[0046] The first-stage movement is horizontal movement: applying a force to the driving device so that the second driving block 23 and the first driving block 24 move horizontally on the track groove 31. At the same time, the limit protrusion 25 provided on the second connecting rod will disengage from the limit chute 33 on the driving device 3, thereby realizing the unlocking of the second connecting rod 21 in the Z direction;

[0047] The second-stage movement is the lifting movement: the second driving block 23 moves upward along the track groove 31, and the first driving block 24 moves horizontally;

[0048] The third-stage movement is the locking movement: the second driving block 23 moves horizontally, and the first driving block 24 moves downward along the track groove 31 to stop at the locking point; after the above operations, the second connecting rod 21 will move to the maximum lifting position;

[0049] The fourth stage of operation is the lifting of the first bracket, that is, the front end of the glass is lifted: after the driving device 3 completes the third stage, it will drive the second connecting rod 21 to move towards the tail of the skylight together. Since both the first connecting rod 11 and the second connecting rod 21 are fixedly connected to the glass, at this time, the first connecting rod 11 will also move towards the tail of the skylight simultaneously, and the limiting device 14 will lift upward along the guide rail chute 61, thereby realizing the lifting of the front end of the glass;

[0050] The fifth stage of operation is full open; the tail of the skylight is operated under the drive of the driving device 3 to fully open the skylight;

[0051] As Figure 8 、 9 As shown, for the above-mentioned skylight mechanical group, the distance H between the adjustment connection hole 121 and the sliding limiting device 14 and the height difference L1 between the sliding limiting device 14 and the support sliding foot 132 determine the climbing height of the front end of the movable skylight glass. In this embodiment, the height difference L1 between the sliding limiting device 14 and the support sliding foot 132 in the closed state is optimized and upgraded: so that with the distance H between the adjustment connection hole 121 and the sliding limiting device 14 unchanged, the position of the sliding limiting device 14 is fixed, the distance L1 between the sliding limiting device 14 and the support sliding foot 132 is reduced, the rotation center of the pin shaft 131 is aligned with the center line of the support sliding foot 132, and at the same time, the first chute spacing L2 is increased, so that the climbing height of the first connecting rod in the Z direction is significantly increased. The height difference between the lower limit of the front ear piece of the movable skylight glass and the upper surface of the fixed skylight glass is 10 mm, and this height difference is greater than the safety clearance of 5 mm, avoiding the scratching of the upper surface of the fixed skylight glass by the movable skylight glass. At the same time, the movable skylight glass can also run completely to the upper end of the fixed skylight glass 5, avoiding the defect of insufficient field of view caused by the exposure of the movable skylight glass.

[0052] Schematically, it can be understood that the connection method of the second connector and the second connecting rod is the same as that of the first connecting rod and the first connector, and the structure with the limiting function on the second connector is arranged at the front end; at the same time, a card slot with a corresponding limiting function mechanism is provided at the rear end of the driving device. When the structure with the limiting function is located in the card slot, the card slot limits the position of the second connector in the closed state.

[0053] Embodiment 2

[0054] In order to further improve the stability of glass installation, this embodiment further provides a skylight mechanical group. On the basis of the skylight mechanical group in the above-mentioned Embodiment 1, the shape of the first mounting bracket and the shape of the second connector are adjusted, and at the same time, a first connection locking groove matching the first mounting bracket and a second connection locking groove matching the second connector are provided on the driving device. Specifically,

[0055] As Figure 4 、 10As shown in Figures 11 and 12, as a further preferred embodiment, for the above-mentioned skylight mechanical group, the first mounting bracket 122 is provided with a first connection locking projection 1221 that matches a first connection locking groove 3310 on a driving device. When the first connection locking projection is in the state of being located in the first connection locking groove, the first mounting bracket 122 is in a locking device. When producing and installing the skylight glass, setting the first connection locking projection 1221 in the first connection locking groove aims to facilitate the fixation of the skylight glass. At the same time, during actual use, setting the first connection locking projection in the first connection locking groove can, on the one hand, provide auxiliary support for the skylight glass through this groove (since the present utility model cancels the conventional long-strip glass mounting bracket, and only the first mounting bracket 122 and the second mounting bracket are fixedly connected to the skylight glass, so the first mounting bracket 122 and the second mounting bracket are relatively more stressed. The first connection locking groove and the second locking groove described below can provide auxiliary support for the skylight glass, reducing the pressure on the first connector and the second connector), and at the same time, it is also beneficial to improve the stability of the skylight glass during driving.

[0056] As Figure 11 , 12 As shown in Figures 13 and 14, as a further preferred embodiment, for the above-mentioned skylight mechanical group, the second connector 22 is provided with a second connection locking projection 2200 that matches a second connection locking groove 3320 on a driving device. When the second connection locking projection is in the state of being located in the second connection locking groove, the second connector is in a locking device. When producing and installing the skylight glass, setting the second connection locking projection in the second connection locking groove aims to facilitate the fixation of the skylight glass. At the same time, during actual use, setting the second connection locking projection in the second connection locking groove can, on the one hand, provide auxiliary support for the skylight glass, and at the same time, it is also beneficial to improve the stability of the skylight glass during driving.

[0057] It should be noted that the first connection locking groove and the second connection locking groove are both optional technical solutions. In actual production, the first connection locking groove and the second connection locking groove may not be provided, or only any one of the first connection locking groove and the second connection locking groove may be provided, or both the first connection locking groove and the second connection locking groove may be provided. Those skilled in the art can make corresponding adjustments according to the production requirements involved, and will not be elaborated here one by one.

[0058] On the other hand, the present utility model further provides an automobile, which includes the above-mentioned skylight mechanical group. An automobile in this embodiment includes all the advantages of the above-mentioned skylight mechanical group.

[0059] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model.
