Description

A pressing mode car panorama skylight for on car

Technical Field

The invention belongs to the field of automobile panoramic skylights, and particularly relates to a compression type automobile panoramic skylight used for an automobile.

Background

Panoramic sunroof for a motor vehicle is relative to a conventional sunroof. Generally, the panoramic sunroof is a roof with a large skylight area or even a whole piece of glass, and when the panoramic sunroof sits in a vehicle, the scene above the roof can be seen in a large view and the visual field is wide; at present, more panoramic skylights are formed by a front piece of glass and a rear piece of glass, so that the scenes above the roof of a car can be seen by two rows of seats in the front and the rear rows of seats respectively.

The traditional automobile panoramic sunroof is divided into a closed type and a sectional opening type according to the opening form;

the closed panoramic sunroof is formed by a whole piece of glass and cannot be opened; the skylight is actually a large-area glass roof, and the light transmission area of the skylight is large due to the fact that no segmented structure exists. Because the air can not be opened, the ventilation function can not be realized.

The segmented opening type skylight is divided into a double-skylight type panoramic skylight and a splicing type panoramic skylight. Two skylight formula panorama skylight: at the top of the front seat, the common skylight is still the same as the standard skylight, and then at the top of the rear seat, a designer adds an unopened skylight, so that more light transmission quantity can be brought to the interior of the vehicle, and the effect similar to a panoramic skylight is achieved. Splicing type panoramic sunroof: the skylight consists of a front skylight and a rear skylight, and the light transmission quantity of the skylights is influenced only by the fact that the front skylight and the rear skylight are overlapped.

In view of the above-mentioned disadvantages of the conventional panoramic sunroof, it is necessary to design a panoramic sunroof having a large sunroof area, a sunroof glass that can be fully opened, and a sunroof that is not partially covered by the sunroof in a closed state.

The invention designs a compression type automobile panoramic sunroof for an automobile, which solves the problems.

When the two shifting rods are shifted by the two tail ends of the C-shaped block A or the C-shaped block B, the slide bar is driven by the two shifting rods to gradually remove the limitation on the outer plates of the two expansion plates, and the spring D which is always in a compressed state can drive the two expansion plates to integrally retract into the corresponding sliding groove I, so that the driving mechanism A and the corresponding C-shaped block A can be separated, or the driving mechanism B and the C-shaped block B in the corresponding C-shaped block mechanism can be separated. The spring E which is always in a compressed state ensures that when the spring E is not acted by the C-shaped block A or the C-shaped block B, the length of the inner plate inclined plane end of each expansion plate extending out of the two sides of the corresponding driving strip under the action of the corresponding pre-pressed spring E is enough, and the inner plate ends of the two expansion plates can be effectively matched with the clamping grooves B in the C-shaped block A when the driving strip drives the inner plate ends of the two corresponding expansion plates to enter the clamping grooves B in the inner wall of the corresponding C-shaped block A and then pulls back the C-shaped block A; or when the driving strip drives the inner plate ends of the two corresponding telescopic plates to enter the corresponding C-shaped block B to interact with the two slide blocks A and pull back the C-shaped block mechanism, the inner plate ends of the two telescopic plates can be effectively matched with the two slide blocks A in the C-shaped block mechanism, so that the driving strip which retracts under the driving of the electric driving module B is ensured to drive the corresponding skylight glass to be smoothly opened through the inner plate ends of the two telescopic plates and the C-shaped block A or the C-shaped block mechanism matched with the inner plate ends.

Compared with the traditional automobile panoramic sunroof, the sunroof glass is opened and closed from two sides of the automobile body, so that the movement of the sunroof glass is effectively shortened, and the continuous panoramic glass sunroof above the front row and the rear row of seats of the automobile is realized; compared with the traditional panoramic sunroof of the automobile, the driving mechanism A and the driving mechanism B for driving the sunroof glass to open and close can be completely recovered after the sunroof glass is closed, so that the middle part of the sunroof after the sunroof glass is closed is not partially shielded, the visual field range of the sunroof is wider, the viewing effect is better, meanwhile, the circulation of air inside and outside the automobile can be realized, the oppressive feeling generated when the sunroof is in a closed automobile for a long time is avoided, and the automobile is more comfortable to ride.

As shown in fig. 14, the spring a42 is an extension spring, and the spring a42 is always in an extended state; as shown in fig. 19, 26 and 29, spring B61, spring C79, spring D89 and spring E88 are all compression springs, and spring B61, spring C79, spring D89 and spring E88 are all in a compressed state at all times; the spring constant of spring C79 is greater than the spring constant of spring D89 and spring E88. The spring a42, which is always in tension, can complete the complete return of the respective slide a36 on the respective slide C29. The spring B61, which is always in compression, keeps the three prongs of the corresponding latch B57 always outside the anchor block 52 and in operative engagement with the corresponding latch a 50. When the two shift levers 80 are not shifted by the two ends of the C-shaped block a25 or the C-shaped block B28, the slide bar 76 overcomes the spring D89 mounted on the telescopic plate 81 under the action of the spring C79 in the compressed state to press the outer plates 82 of the two telescopic plates 81, so that the outer plates 82 of the two telescopic plates 81 respectively drive the inclined end of the inner plate 85 to protrude out of the side of the driving bar 71 through the corresponding spring E88. When the two shift levers 80 are shifted by the two ends of the C-shaped block a25 or the C-shaped block B28, the slide bar 76 is driven by the two shift levers 80 to gradually release the restriction on the outer plates 82 of the two expansion plates 81, and at this time, the spring D89, which is always in a compressed state, can drive the two expansion plates 81 to integrally retract into the corresponding sliding groove I74, which is beneficial to the separation of the driving mechanism a70 from the corresponding C-shaped block a25 or the separation of the driving mechanism B39 from the C-shaped block B28 in the corresponding C-shaped block mechanism 27. The spring E88 which is always in a compressed state ensures that when the spring E88 is not acted by the C-shaped block A25 or the C-shaped block B28, the length of the inclined plane end of the inner plate 85 of the telescopic plate 81 extending out of two sides of the corresponding driving strip 71 under the action of the corresponding pre-pressed spring E88 is enough, and ensures that when the driving strip 71 drives the plate ends of the inner plates 85 of the corresponding two telescopic plates 81 to enter the clamping grooves B26 of the inner wall of the corresponding C-shaped block A25 and then pulls back the C-shaped block A25, the plate ends of the inner plates 85 of the two telescopic plates 81 can be effectively matched with the clamping grooves B26 in the C-shaped block A25; or when the driving strip 71 drives the inner plate 85 plate ends of the two corresponding telescopic plates 81 to enter the corresponding C-shaped block B28 to interact with the two sliding blocks a36 and pull back the C-shaped block mechanism 27, the inner plate 85 plate ends of the two telescopic plates 81 can effectively cooperate with the two sliding blocks a36 in the C-shaped block mechanism 27, so that the driving strip 71 retracted under the driving of the electric driving module B93 is ensured to drive the corresponding skylight glass 16 to be smoothly opened through the inner plate 85 plate ends of the two telescopic plates 81 and the C-shaped block a25 or the C-shaped block mechanism 27 cooperating therewith.

The sealing strip 24 is matched with the skylight glass 16 and the top 1 of the carriage in a sealing way by adopting the prior art.

The spring C79 has a large elastic coefficient, and the spring C79 does not deform further in the process of closing the driven skylight glass 16; when the two roof panes 16 are completely closed and need to be pressed against each other, the spring C79 will be deformed by the corresponding drive module B.

The number of positive rotation turns of the electric drive module B93 in the driving mechanism A70 is larger than that of the positive rotation turns of the electric drive module B93 in the process of closing the driven skylight glass 16, so that the driving mechanism A70 is guaranteed to drive the skylight glass 16 to be closed and interact with the C-shaped block A25 under the continuous operation to complete the smooth separation of the driving mechanism A70 and the corresponding C-shaped block A25, and the driving mechanism A70 is smoothly retracted after the skylight glass 16 is closed. The number of positive rotation turns of the electric drive module B93 in the driving mechanism B39 is larger than that of the positive rotation turns of the electric drive module B93 in the process of closing the driven skylight 16, so that the driving mechanism B39 is guaranteed to drive the skylight 16 to be closed and interact with the C-shaped block B28 under the continuous operation to complete the smooth separation of the driving mechanism B39 and the corresponding C-shaped block B28, and the smooth retraction of the driving mechanism B39 is realized after the skylight 16 is closed.

The number of positive and negative rotation turns of the electric drive module B93 in the driving mechanism A70 and the driving mechanism B39 is preset and fixed.

The working process of the invention is as follows: according to the invention, the closed state of two pieces of skylight glass 16 is taken as the initial state, the convex sealing gasket 21 is in nested fit with the concave sealing sleeve 18, the convex sealing gasket 21 is extruded and deformed by the convex support 19 and the concave sealing sleeve 18, and the convex sealing gasket 21 effectively seals the joint between the two pieces of skylight glass 16; the two driving mechanisms A70 and the four driving mechanisms B39 are respectively contracted into the corresponding chutes B4 without forming partial obstruction on the visual field; the slide bars 76 in the driving mechanism A70 and the driving mechanism B39 respectively press the outer plates 82 of the two corresponding telescopic plates 81 to the outer parts of the two sides of the driving bar 71 under the action of corresponding pre-pressing springs C79, and two inclined planes C77 on the slide bars 76 are respectively contacted with inclined planes D84 at the plate ends of the outer plates 82 of the two telescopic plates 81; the inclined plane ends of the inner plates 85 of the two telescopic plates 81 matched with the slide bars 76 extend out of the corresponding sliding grooves I74; spring C79, spring D89 and spring E88 are all in a compressed energy storage state; the three-prong side surface of the fixture block B57 in the limiting mechanism 51 contacts with the three-prong side surface of the fixture block a50 in the corresponding C-shaped block mechanism 27 and limits the opening of the corresponding skylight glass 16 driven by the C-shaped block mechanism 27, so that the four C-shaped block mechanisms 27 respectively keep mutual compression on the two skylight glasses 16 under the limiting of the corresponding limiting mechanism 51, a large extrusion force is generated between the two skylight glasses 16, and effective extrusion sealing between the convex sealing gasket 21 and the concave sealing sleeve 18 is guaranteed; a certain distance is reserved between one end of the screw 67 in the limiting mechanism 51 and the end face of the corresponding fixture block B57, the distance does not interfere the sliding of the fixture block B57 along the sliding groove E33 in the corresponding fixture block 52 under the action of the fixture block A50, and the spring B61 is in a compressed state; the two slide blocks A36 in the C-shaped block mechanism 27 are respectively located at the extreme positions of one end of the corresponding slide groove C29 away from the same side of the C-shaped block B28 under the pulling of the corresponding spring A42.

When the plate ends of the inner plates 85 of the two telescopic plates 81 in the driving mechanism A70 respectively reach the range of the two clamping grooves B26 on the inner wall of the corresponding C-shaped block A25 at the same time, under the reset action of the corresponding spring E88, the inner plates 85 of the two telescopic plates 81 instantly enter the corresponding clamping grooves B26 and limit the retraction movement of the driving strip 71 relative to the C-shaped block A25, and the two shift levers 80 are just contacted with the end faces of the two ends of the C-shaped block A25; the plate ends of the inner plates 85 of the two telescopic plates 81 in the driving mechanism B39 just cross the inner walls of the corresponding C-shaped blocks B28 at the same time and slide symmetrically on two sliding blocks A36 in the sliding groove C29 respectively; under the reset action of the corresponding spring E88, the inclined plane ends of the inner plates 85 of the two telescopic plates 81 in the driving mechanism B39 instantly enter the corresponding sliding grooves C29 to be in contact with the side surfaces of the corresponding sliding blocks A36 and limit the retraction movement of the driving strip 71 relative to the C-shaped block B28, and the two shift rods 80 in the driving mechanism B39 are just in contact with the end surfaces of the two tail ends of the C-shaped block A25.

At the moment, the control system firstly controls the electric drive module B93 in the driving mechanism B39 to run reversely; an electric drive module B93 in the driving mechanism B39 drives a corresponding driving strip 71 to retract towards a corresponding sliding groove B4 through a corresponding gear E92, and the driving strip 71 drives all components mounted on the driving strip to retract synchronously; the inner plates 85 of the two expansion plates 81 exposed at the two sides of the driving bar 71 interact with the two slide blocks A36 on the inner wall of the corresponding C-shaped block B28; at this time, the C-shaped block mechanism 27 is kept still under the mutual limiting action of the corresponding clamping block a50 and the clamping block B57 in the corresponding limiting mechanism 51, so that the driving bar 71 in the driving mechanism B39 which retracts into the sliding groove B4 drives the two sliding blocks a36 to synchronously slide in the sliding groove C29 on the inner wall of the C-shaped block B28 through the two telescopic plates 81, and the two shift levers 80 are separated from the C-shaped block B28 and start to be far away from the C-shaped block B28; the two sliding blocks A36 are respectively driven by the corresponding connecting blocks 37 and the sliding block B38 and the rack A40 synchronously move; the slide block B38 stretches the corresponding spring A42, and the rack A40 stretches the corresponding spring A42 through the tension spring plate 43; the rack A40 drives the rack B48 to vertically move downwards through the gear A44, the rotating shaft 45 and the gear B46, and the rack B48 drives the clamping block A50 arranged on the rack B48 to synchronously move; the three-strand fork of the fixture block A50 and the three-strand fork of the fixture block B57 in the corresponding limiting mechanism 51 move in a staggered manner; when the two sliding blocks a36 reach the limit position of the corresponding sliding groove C29 under the driving of the inner plate 85 end of the corresponding telescopic plate 81, respectively, the distance between the two shift levers 80 and the C-shaped block B28 reaches the limit, the three-strand fork of the fixture block a50 in the C-shaped block mechanism 27 is just completely staggered with the three-strand fork of the corresponding fixture block B57, the fixture block a50 is completely separated from the fixture block B57, and the fixture block B57 does not limit the C-shaped block mechanism 27 where the fixture block a50 is located. At the moment, the control system controls the electric drive module B93 in the driving mechanism B39 to stop running and self-lock, and simultaneously controls the electric drive modules B93 in the two driving mechanisms A70 to run reversely; at this time, the limit of the limit mechanism 51 on the corresponding C-shaped block mechanism 27 is released, so that the electric drive module B93 in the driving mechanism a70 drives the corresponding driving bar 71 to retract into the corresponding sliding groove B4 through the corresponding gear E92, and the driving bar 71 drives all the components mounted thereon to retract synchronously; the inner plates 85 of the two expansion plates 81 exposed at the two sides of the driving bar 71 interact with the inner walls of the clamping grooves B26 on the inner walls of the corresponding C-shaped blocks A25 and drive the corresponding skylight glass 16 to open through the C-shaped blocks A25; the convex support 19 mounted on one skylight glass 16 drives the corresponding convex sealing gasket 21 to separate from the concave sealing sleeve 18 mounted on the other skylight glass 16; the guide wheels 23 on both sides of the skylight glass 16 are driven by the glass to rotate and play an effective guide role for the movement of the skylight glass 16, so that the skylight glass 16 is prevented from being stuck due to the deflection in the horizontal direction in the movement process. Each skylight glass 16 drives two C-shaped block mechanisms 27 installed on the skylight glass to move synchronously, a C-shaped block B28 in each C-shaped block mechanism 27 moves relative to a corresponding driving mechanism B39, and the three-strand fork of a fixture block A50 in each C-shaped block mechanism 27 and the three-strand fork of a fixture block B57 form cross motion.

When the fixture block A50 in the C-shaped block mechanism 27 is completely separated from the fixture block B57 in the corresponding limiting mechanism 51, the two sliding blocks A36 in the C-shaped block mechanism 27 are completely reset under the reset action of the corresponding spring A42, the two shift levers 80 in the driving mechanism B39 are in contact with two end faces of the corresponding C-shaped block B28, and the plate ends of the inner plates 85 of the two telescopic plates 81 in the driving mechanism B39 are in contact with the side faces of the two sliding blocks A36 in the corresponding C-shaped block mechanism 27 respectively. At the moment, the control system controls the electric drive module B93 in the four drive mechanisms B39 to simultaneously run in the reverse direction; since the two driving mechanisms a70 interact with the corresponding C-shaped block a25 at the same time and drive the two skylight glasses 16 and the four driving mechanisms installed on the skylight glasses 16 to move synchronously, the driving bars 71 in the four driving mechanisms B39 drive the corresponding two shift levers 80 and the inner plates 85 of the two expansion plates 81 to move synchronously with the corresponding C-shaped block mechanisms 27, and no interaction occurs any more; that is, when the limiting mechanism 51 releases the restriction of the corresponding C-block mechanism 27, the opening of the roof glass 16 is completely performed by the drive mechanism a70, and the drive mechanism B39 is only driven by the corresponding electric drive module B93 to retract synchronously with the C-block mechanism 27 and the roof glass 16 into the corresponding chute B4. When the driving bars 71 in the driving mechanism A70 and the driving mechanism B39 retract to the extreme positions of the corresponding chutes B4, the skylight glass 16 is just fully opened; a concave sealing sleeve 18 or a convex support 19 arranged on the skylight glass 16 is tightly attached to the inner wall of the skylight opening 14; at this time, the control system controls the electric drive module B93 in the drive mechanism a70 and the drive mechanism B39 to stop running, and the complete opening of the two roof glasses 16 is completed; the plate ends of the inner plates 85 of the two expansion plates 81 in the driving mechanism A70 are still positioned in the two clamping grooves B26 on the inner wall of the corresponding C-shaped block A25 and are respectively clung to the inner walls of the corresponding clamping grooves B26, and the two shift levers 80 are still respectively contacted with the end faces of the two tail ends of the C-shaped block A25; the plate ends of the inner plates 85 of the two telescopic plates 81 in the driving mechanism B39 are still positioned in the two sliding grooves C29 on the inner wall of the corresponding C-shaped block B28 and are respectively clung to the side surfaces of the corresponding sliding block A36, and the two shift levers 80 are still respectively contacted with the end surfaces of the two ends of the C-shaped block B28.

During the process of crossing between the fixture block a50 and the corresponding fixture block B57 in the C-shaped block mechanism 27 in the horizontal direction, due to the relative limitation of the fixture block a50 and the fixture block B57 in the vertical direction, the fixture block a50 makes the corresponding slide block a36 not move relative to the corresponding C-shaped block B28 under the reset action of the corresponding spring a42, so that the slide block a36 connected with the rack a40 is temporarily separated from the inner plate 85 of the corresponding telescopic plate 81, the other slide block a36 keeps in contact with the plate end of the inner plate 85 of the corresponding telescopic plate 81 under the reset action of the corresponding spring a42 and is gradually reset in the corresponding sliding groove C29, and the two shift levers 80 in the driving mechanism B39 are quickly close to the C-shaped block B28 in the corresponding C-shaped block mechanism 27. When the clamping block A50 in the C-shaped block mechanism 27 is completely separated from the clamping block B57 in the corresponding limiting mechanism 51, under the reset action of the corresponding spring A42, the sliding block A36 connected with the rack A40 is instantly reset in the corresponding sliding groove C29, the sliding block A36 drives the corresponding clamping block A50 to be instantly reset relative to the C-shaped block B28 through a series of transmission, the clamping block A50 is opposite to the inclined surface A58 on the clamping block B57, and the two shift levers 80 in the driving mechanism B39 are again in contact with the two end surfaces of the corresponding C-shaped block.

After the inclined plane ends of the inner plates 85 of the two telescopic plates 81 in the driving mechanism B39 are separated from the two end faces of the corresponding C-shaped block B28 and enter the C-shaped block B28, the inclined plane ends of the inner plates 85 of the two telescopic plates in the driving mechanism B39 respectively reach the range of the part, between the corresponding sliding block A36 and one end of the C-shaped block B28, of the sliding chute C29 on the inner wall on the same side of the C-shaped block B28 under the continuous driving of the driving strip 71; the plate ends of the inner plates 85 of the two telescopic plates 81 in the driving mechanism B39 enter the corresponding chutes C29 instantly under the reset action of the corresponding springs E88; the continuously moving driving strip 71 continuously drives the plate ends of the inner plates 85 of the two telescopic plates 81 to move along the sliding groove C29; when the plate ends of the inner plates 85 of the two telescopic plates 81 in the driving mechanism B39 meet and interact with the two sliding blocks A36 respectively, the two sliding blocks A36 at the extreme positions of the corresponding chutes C29 compress the inner plates 85 of the two telescopic plates 81 towards the corresponding outer plates 82 respectively, and the springs E88 in the telescopic plates 81 are further compressed to store energy; when the plate ends of the inner plates 85 of the two telescopic plates 81 in the driving mechanism B39 just pass over the corresponding slide block A36 under the driving of the continuously moving driving bar 71, the inner plates 85 of the two telescopic plates 81 in the driving mechanism B39 enter the corresponding chutes C29 instantly under the resetting action of the corresponding springs E88.

When the two pieces of skylight glass 16 are in the open state, because the electric drive module B93 in the driving mechanism a70 and the driving mechanism B39 is in the stop self-locking state, the electric drive module B93 drives the corresponding skylight glass 16 to keep the open state and still through a series of transmission, thereby ensuring that the skylight glass 16 does not shake under the bumping action of the vehicle in the running process of the vehicle.

When the skylight glass 16 needs to be closed, the control system simultaneously controls the driving mechanism A70 and the electric drive module B93 in the driving mechanism B39 to operate, the electric drive module B93 in the driving mechanism A70 drives the corresponding driving strip 71 to move towards the middle of the skylight window 14 along the corresponding sliding groove B4 through the corresponding gear E92, and the electric drive module B93 in the driving mechanism B39 drives the corresponding driving strip 71 to move towards the middle of the skylight window 14 along the corresponding sliding groove B4 through the corresponding gear E92; two shifting rods 80 in the driving mechanism A70 drive the corresponding skylight glass 16 to synchronously close through the corresponding C-shaped block A25, two shifting rods 80 in the driving mechanism B39 drive the corresponding skylight glass 16 to synchronously close through the corresponding C-shaped block B28, each skylight glass 16 performs closing movement under the combined action of the driving mechanism A70 and the two driving mechanisms B39, and the skylight glass 16 drives a plurality of guide wheels 23 on two sides to rotate; in the process of closing the skylight glass 16, the plate ends of the inner plates 85 of the two telescopic plates 81 in the driving mechanism A70 are always attached to the inner walls of the corresponding clamping grooves B26 on the inner walls of the C-shaped blocks, and the plate ends of the inner plates 85 of the two telescopic plates 81 in the driving mechanism B39 are always attached to the side faces of the two sliding blocks A36 on the inner walls of the C-shaped blocks B28.

When the fixture block A50 in the C-shaped fixture mechanism 27 meets and interacts with the three-prong inclined surface A58 of the fixture block B57 in the corresponding limiting mechanism 51, the fixture block A50 in the C-shaped fixture mechanism 27 pushes the fixture block B57 to retract into the sliding groove F53 on the corresponding fixture block 52 through the inclined surface A58 of the fixture block B57, the fixture block B57 does not form a barrier to the movement of the corresponding C-shaped fixture mechanism 27 along with the closed skylight glass 16, and the spring B61 is further compressed to store energy; due to the large spring rate of spring C79, during the interaction between latch A50 and latch B57, spring C79 does not undergo further compression deformation and the two levers 80 of the drive mechanism B39 do not move relative to the corresponding drive bar 71.

When the two pieces of skylight glass 16 are completely closed under the drive of the drive mechanism A70 and the drive mechanism B39, the convex sealing gaskets 21 arranged on the two pieces of skylight glass 16 are in sealing fit with the convex sealing sleeves, the clamping block A50 in the drive mechanism B39 just crosses the inclined plane A58 and the inclined plane B59 on the clamping block B57 in the corresponding limiting mechanism 51, and the pressing on the clamping block B57 is released; under the reset action of the spring B61 in the corresponding limiting mechanism 51, the fixture block B57 is reset instantly to be in contact with the side surface of the fixture block A50 and restore the relative initial state of the fixture block A50, and the limiting mechanism 51 restores the limit of the corresponding C-shaped fixture mechanism 27. At the moment, the driving mechanism A70 and the electric drive module B93 in the driving mechanism B39 continue to operate, the electric drive module B93 in the driving mechanism A70 continues to drive the corresponding driving strip 71 to move relative to the C-shaped block A25 through the corresponding gear E92, and the plate ends of the inner plates 85 of the two telescopic plates 81 in the driving mechanism A70 are separated from the inner walls of the corresponding clamping grooves B26 on the inner wall of the C-shaped block A25; two shift levers 80 on two sides of a driving bar 71 in the driving mechanism A70 respectively move along the corresponding sliding grooves H73 relative to the driving bar 71 towards the retraction direction of the driving bar 71 under the action of two end faces of the C-shaped block A25; two shift levers 80 in the driving mechanism A70 drive the corresponding slide bars 76 to move synchronously, the slide bars 76 compress the damping rods 78, and the spring C79 is further compressed to store energy; the slider 76 in the drive mechanism a70 gradually releases the restriction on the outer plates 82 of the two expansion plates 81; the outer plates 82 of the two expansion plates 81 in the driving mechanism a70 respectively drive the corresponding inner plates 85 to rapidly retract into the corresponding sliding grooves I74 and separate from the corresponding clamping grooves B26 through the corresponding springs E88 under the action of the corresponding pre-pressing springs D89. Meanwhile, the electric drive module B93 in the driving mechanism B39 drives the corresponding driving strip 71 to move relative to the corresponding C-shaped block B28 continuously through the corresponding gear E92, and the plate ends of the inner plates 85 of the two telescopic plates 81 in the driving mechanism B39 are separated from the side surfaces of the two sliding blocks A36 on the inner wall of the C-shaped block B28; two shift levers 80 on two sides of a driving bar 71 in the driving mechanism B39 respectively move along the corresponding sliding grooves H73 relative to the driving bar 71 towards the retraction direction of the driving bar 71 under the action of two end faces of the C-shaped block B28; two shift levers 80 in the driving mechanism B39 drive the corresponding slide bars 76 to synchronously move, the slide bars 76 compress the damping rods 78, and the spring C79 is further compressed to store energy; the slider 76 in the drive mechanism B39 gradually releases the restriction on the outer plates 82 of the two expansion plates 81; the outer plates 82 of the two telescopic plates 81 in the driving mechanism B39 respectively drive the corresponding inner plates 85 to rapidly retract into the corresponding sliding grooves I74 through the corresponding springs E88 under the action of the corresponding pre-pressing springs D89 and to separate from the corresponding sliding grooves C29 and the sliding blocks a36 in the sliding grooves C29.

When the inner plates 85 of the two telescopic plates 81 in the driving mechanism A70 are completely retracted into the corresponding sliding grooves E33 and completely separated from the corresponding clamping grooves B26, the movement of the two shift levers 80 in the driving mechanism A70 relative to the driving bar 71 reaches the limit, and the two inclined planes C77 on the sliding bar 76 are still in contact with the inclined planes D84 at the plate ends of the outer plates 82 of the two telescopic plates 81 respectively; at the moment, the control system controls the electric drive module B93 in the driving mechanism A70 to rapidly and reversely run, and the electric drive module B93 drives the driving strip 71 to rapidly retract through a series of transmission; since the damping rod 78 in the driving mechanism a70 plays a damping role at this time, the slide bar 76 cannot immediately generate a return movement relative to the driving bar 71 under the return action of the spring C79, the plate ends of the inner plates 85 of the two telescopic plates 81 cannot immediately slide out of the corresponding sliding grooves I74 under the driving of the slide bar 76, and the inner plates 85 of the two telescopic plates 81 in the driving mechanism a70 are temporarily in a state of not restricting the retraction movement of the driving bar 71 relative to the C-shaped block a 25; under the drive of an electric drive module B93 in a driving mechanism A70, one end of a driving strip 71 is quickly separated from a C-shaped block A25, and the plate ends of inner plates 85 of two telescopic plates 81 are quickly separated from the C-shaped block A25; after the driving bar 71 in the driving mechanism a70 is quickly separated from the C-shaped block a25, under the combined reset action of the spring C79 and the damping rod 78, the slide bar 76 starts to be reset slowly relative to the driving bar 71, and the slide bar 76 drives the two shift levers 80 and the two expansion plates 81 to be reset slowly relative to the driving bar 71.

When the inner plates 85 of the two telescopic plates 81 in the driving mechanism A70 are completely retracted into the corresponding sliding groove E33 and completely separated from the corresponding clamping groove B26, the inner plates 85 of the two telescopic plates 81 in the driving mechanism B39 are completely retracted into the corresponding sliding groove E33 and completely separated from the corresponding sliding groove C29 and the sliding block A36, the movement of the two shift levers 80 in the driving mechanism B39 relative to the driving bar 71 reaches the limit, and the two inclined surfaces C77 on the sliding bar 76 in the driving mechanism B39 are still respectively contacted with the inclined surfaces D84 at the plate ends of the outer plates 82 of the two telescopic plates 81; at the moment, the control system controls the electric drive module B93 in the driving mechanism B39 to rapidly and reversely run, and the electric drive module B93 in the driving mechanism B39 drives the corresponding driving strip 71 to rapidly retract through a series of transmission; since the damping rod 78 in the driving mechanism B39 plays a damping role at this time, the slide bar 76 in the driving mechanism B39 cannot immediately generate a return motion relative to the driving bar 71 under the return action of the corresponding spring C79, the plate ends of the inner plates 85 of the two telescopic plates 81 cannot immediately slide out of the corresponding sliding groove I74 under the driving of the slide bar 76, and the inner plates 85 of the two telescopic plates 81 in the driving mechanism B39 are temporarily in a state of not limiting the retraction motion of the driving bar 71 relative to the C-shaped block B28; under the driving of an electric drive module B93 in a driving mechanism B39, one end of a driving strip 71 in the driving mechanism B39 is quickly separated from a corresponding C-shaped block B28, and the plate ends of inner plates 85 of two telescopic plates 81 are quickly separated from the C-shaped block B28; after the driving bar 71 in the driving mechanism B39 is quickly separated from the C-shaped block B28, under the combined return action of the spring C79 and the damping rod 78 in the driving mechanism B39, the slide bar 76 in the driving mechanism B39 starts to be slowly returned relative to the driving bar 71, and the slide bar 76 drives the two shift levers 80 and the two expansion plates 81 to be slowly returned relative to the driving bar 71.

When the driving bar 71 in the driving mechanism a70 is fully retracted into the corresponding sliding groove B4 under the driving of the electric drive module B93, the driving bar 71 in the driving mechanism B39 is also fully retracted into the corresponding sliding groove B4 under the driving of the corresponding electric drive module B93, the shift lever 80 in the driving mechanism a70 and the driving mechanism B39 is fully reset relative to the corresponding driving bar 71, the telescopic rods in the driving mechanism a70 and the driving mechanism B39 are fully reset relative to the corresponding driving bar 71, and the closing of the skylight glass 16 is finished.

When the shift lever 80 in the driving mechanism a70 and the driving mechanism B39 is worn due to repeated contact with the C-shaped block a25 or the C-shaped block B28, which may cause the driving mechanism a70 and the driving mechanism B39 to drive the skylight glass 16 through the C-shaped block a25 and the C-shaped block B28, respectively, and the skylight glass 16 cannot be completely pressed and closed, when the shift lever 80 is worn and the driving mechanism a70 and the driving mechanism B39 drive the skylight glass 16 to be completely closed, the fixture block a50 in the C-shaped block mechanism 27 and the fixture block B57 in the corresponding limiting mechanism 51 cannot completely and relatively reset, and the fixture block a50 may contact with the inclined surface B59 of the fixture block B57, so that the fixture block B57 cannot completely reset, and the C-shaped block mechanism 27 and the skylight glass 16 in the closed state cannot be effectively limited to the initial state. At this time, the electric drive module a69 in the limiting mechanism 51 is controlled to operate by the in-vehicle control system, the electric drive module a69 drives the gear C64 to rotate relative to the fixed block 52 through the gear D68, and the gear C64 drives the screw 67 to rotate and enables the screw 67 to move in the axial direction towards the direction of the block B57 in the fixed block 52; when the end surfaces of the screw 67 and the fixture block B57 meet and interact with each other, the fixture block B57 can be quickly reset under the pushing of the screw 67, and the spring B61 in the limiting mechanism 51 is quickly restored to the initial state; the fixture block B57 which is pushed to reset by the screw 67 drives the fixture block A50 to move continuously towards the glass closing direction through the inclined plane B59, and the fixture block A50 drives the C-shaped fixture block mechanism 27 and the skylight glass 16 to move continuously through a series of transmission; when the clamping block A50 completely passes through the clamping block B57 and the limitation on the clamping block B57 is removed, the control system controls the electric drive module A69 to run reversely, and the electric drive module A69 running reversely drives the screw 67 to reset rapidly through a series of transmission; meanwhile, the fixture block B57 is quickly reset under the continuous reset action of the corresponding spring B61 and the limitation of the fixture block A50 is restored, and at the moment, the skylight glass 16 is also tightly closed. When the screw 67 is completely reset, the control system controls the electric drive module a69 to stop running.

In conclusion, the beneficial effects of the invention are as follows: the skylight glass 16 is opened and closed from two sides of the vehicle body, so that the movement of the skylight glass 16 is effectively shortened, and the continuous panoramic glass skylight above the front row and the rear row of seats of the vehicle is realized; compared with the traditional panoramic sunroof of the automobile, the driving mechanism A70 and the driving mechanism B39 for driving the sunroof glass 16 to open and close can be completely recovered after the sunroof glass 16 is closed, so that the middle part of the sunroof after the sunroof glass 16 is closed is not partially shielded, the visual field range is wider, the viewing effect is better, meanwhile, the circulation of air inside and outside the automobile can be realized, the sense of oppression generated when the sunroof is in a closed automobile for a long time is avoided, and the automobile can be more comfortable to ride.
