Description

Technical Field

[0001] The utility model relates to the technical field of automobile sunroofs, in particular to a mechanical assembly of an outward-opening small sunroof. Background Art

[0002] At present, most family cars on the market are equipped with openable sunroofs, among which outward-opening sunroofs are particularly common. Such outward-opening sunroofs usually include a carrier that carries the roof glass and connecting rods arranged at both ends of the carrier. The connecting rods support the carrier through the guidance of guide grooves, so that the carrier can slide open in a tilted posture. In addition, in order to ensure the stability of the sunroof in the closed state, it also has limit blocks located at both ends of the carrier. The limit blocks are embedded in the two ends of the sunroof guide rail corresponding to the closed position.

[0003] The limit block occupies a certain height and length space on the guide rail. Especially during the opening process, the limit block needs to move on the guide rail and separate from the carrier. For some models with small roof space and restricted installation environment, due to the short length of the roof guide rail, it is affected by the space behind the guide rail, resulting in the inability to set the above-mentioned limit block on the sunroof guide rail. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a mechanical assembly of an outward-opening small skylight.

[0013] Furthermore, the limit assembly also includes a front guide rod, including a front base connected to the carrier, and a front limit block extending from the front base toward the opening direction of the carrier. A front limit groove is provided on the guide rail, and the front limit block is placed in the front limit groove in an inclined posture in the closed position, and the active slider lifts the front limit block out of the front limit groove during the tilting stroke, and allows the front guide rod to slide in the guide rail.

[0014] Furthermore, the carrier further comprises a front guide groove, the front base is provided with a front guide column inserted into the front guide groove, and the front guide groove is configured to guide the lifting stroke of the carrier.

[0015] Furthermore, the active slider is provided with a front transmission groove open in the opening direction, the front limit block is provided with a front transmission block placed in the guide rail, and the front transmission groove and the front transmission block are provided with first inclined surfaces arranged opposite to each other. The front transmission groove is against the front transmission block during the opening stroke, and the front transmission block is pulled into it, so as to drive the front limit block to disengage from the front limit groove.

[0016] Furthermore, the front guide rod further includes a front rod body connected between the front base and the front limit block, and the rod body is configured to extend along the length direction of the carrier.

[0017] Furthermore, the active slider is connected to a driving flexible shaft, the guide rail includes an opening and closing slide, the carrier, active slider, front guide rod and driving flexible shaft are all arranged to move in the opening and closing slide, and the front guide rod is arranged below the carrier.

[0020] The utility model provides a rear base at the front end of the carrier, and a rear limit block extending in the opening direction on the rear base and limiting each other in the closed position with the rear end of the carrier. During the opening process, the active slider only needs to drive the rear base to translate a certain distance, so that the rear limit block is disengaged from the rear end of the carrier. At this time, the rear base is limited at the end of the translation stroke, forcing it to disengage the transmission from the active slider, so that the carrier can be opened normally, thereby eliminating the need for an embedded limit structure in the guide rail. For guide rails with shorter lengths, the problem of limiting the rear end of the carrier in the closed position and the problem of limited space in the open position are solved. The overall structure is more compact and suitable for roof guide rails with smaller spaces. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] It should be understood that although terms such as upper, middle, lower, top, end, etc. appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for ease of understanding, and are not used to define any direction or order limitation.

[0043] like Figure 1-13 As shown, a mechanical assembly of an outward-opening small skylight includes:

[0044] A guide rail 1, a carrier 2 for supporting the roof panel, and an active slider 3 for driving the carrier 2 to switch between a raised position and a closed position. The carrier 2 is provided with a track groove 2.1, and the active slider 3 is connected to the track groove 2.1 and constrained to slide within the guide rail 1. The front end of the carrier 2 is provided with a front slider 2.3, which is constrained to slide within the guide rail 1 and is hingedly connected to the front slider 2.3 at the front end of the carrier 2, so that the tilting action is performed with the front end of the carrier 2 as the base point.

[0045] The active slider 3 and the carrier 2 are further connected to a limit assembly, which is used to maintain the stability of the carrier 2 in the closed position. The limit assembly includes:

[0046] like Figure 3 、 Figure 5 ,as well as Figures 8 and 9 As shown, the front guide rod 4 includes a front base 4.1 connected to the carrier 2, and a front limit block 4.2 extending from the front base 4.1 toward the opening direction of the carrier 2. The front limit block 4.2 preferably extends below the track groove 2.1, and in the closed position, the active slider 3 is located between the front base 4.1 and the front limit block 4.2. The guide rail 1 is provided with a front limit groove 1.1, which is specifically arranged in the opening and closing slide 9 on the guide rail 1 corresponding to the active slider 3. The front limit block 4.2 is positioned in a downwardly inclined posture in the closed position. The active slider 3 cooperates with the front limit block 4.2 in the lifting stroke and lifts the front limit block 4.2 to disengage from the front limit slot 1.1. At this time, the front guide rod 4 is allowed to slide in the guide rail 1, and the front guide rod 4 is driven by the active slider 3 to slide synchronously while maintaining the posture of cooperating with the active slider 3. In the closing stroke, the active slider 3 drives the carrier 2 to return, and drives the front base 4.1 to return through the carrier 2, so as to realize the synchronous return action of the front guide rod 4 and the carrier 2.

[0047] Among them, the front limit groove 1.1 refers to a through groove opened at the bottom of the opening and closing slide 9 of the guide rail 1, for example in the form of a sheet metal cut, and the bending position of the sheet metal cut forms a guiding surface in the opening direction.

[0048] In this embodiment, the front guide rod 4 is limited by the front guide block extending in the opening direction of the carrier 2 and the guide rail 1, so as to realize the rearward movement of the front end limit position of the carrier 2, thereby avoiding occupying the space between the active slider 3 and the front end of the carrier 2 in the closed position. At the same time, the front base 4.1 located at the front end of the carrier 2 plays a role in maintaining the tilted posture of the carrier 2.

[0049] like Figure 12As shown, as a further embodiment of the front guide rod 4, the front guide rod 4 also includes a front rod body 4.3 connected between the front base 4.1 and the front limit block 4.2, and the front rod body 4.3 is configured to extend along the length direction of the carrier 2. Preferably, the front rod body 4.3 is arranged below the active slider 3, and the carrier 2 is arranged above the active slider 3, and the front rod body 4.3 is configured to have a downward tilt, so that after the carrier 2 returns to the closed position, the front rod body 4.3 actuates the front limit block 4.2 to be placed in the front limit groove 1.1.

[0050] from Figure 9 It can be seen that as an embodiment of the cooperation between the front base 4.1 and the carrier 2, the carrier 2 also includes a front guide groove 2.2, and the front base 4.1 is provided with a front guide column 4.11 which can be slidably inserted into the front guide groove 2.2. The front guide groove 2.2 is configured to guide the lifting stroke of the carrier 2, specifically in an oblique upward posture. During the lifting process, the lifting posture of the carrier 2 is constrained by the front guide column 4.11 and the front guide groove 2.2, and it also serves as a transmission between the carrier 2 and the front guide rod 4 during the return process of the carrier 2.

[0051] In the above embodiment, in the closed position, the front slider 2.3, the front base 4.1, the active slider 3 and the front limit block 4.2 are arranged in sequence from the front end to the rear end of the carrier 2, which fully reduces the horizontal space and vertical space occupied by the front guide rod 4 in the guide rail 1.

[0052] As an implementation method for the transmission of the active slider 3 and the front limit block 4.2, the active slider 3 is provided with a front transmission groove 3.1 open in the opening direction, and the front limit block 4.2 is provided with a front transmission block 4.21 placed in the guide rail 1. The front transmission groove 3.1 and the front transmission block 4.21 are provided with oppositely arranged first inclined surfaces 5. The front transmission groove 3.1 is against the front transmission block 4.21 during the opening stroke, and the front transmission block 4.21 is pulled into it, so as to drive the front limit block 4.2 to disengage from the front limit groove 1.1.

[0053] Preferably, the front transmission groove 3.1 is arranged in a downwardly inclined posture toward the opening direction. During the opening stroke, the front transmission groove 3.1 is abutted against the first inclined surface 5 on the front transmission block 4.21, and the front transmission block 4.21 is shoveled into the front transmission groove 3.1 to form a transmission fit. At this time, the front transmission block 4.21 and the front limit block 4.2 are tilted and ready to disengage from the front limit groove 1.1.

[0054] like Figures 3 to 10As shown, as a further improvement to the front limit block 4.2 and the active slider 3, the front transmission block 4.21 extends on both sides of the front limit block 4.2, so that the front limit block 4.2 and the front transmission block 4.21 form a roughly T-shape. In the closed position, the front limit block 4.2 abuts against the front limit groove 1.1 under the action of the front rod body 4.3, and the front transmission block 4.21 abuts against the opening and closing slide 9 of the guide rail 1 under the action of the front rod body 4.3. The active slider 3 includes two bent side edges 3.3 and a connecting edge 3.4 connected to the upper ends of the two side edges 3.3, wherein the connecting edge 3.4 is An upper guide column 3.5 is provided, which is connected to the track groove 2.1, and defines a space open at the bottom between the two side edges 3.3. The front rod body 4.3 is correspondingly arranged in the space, and two front transmission grooves 3.1 are formed at the bottom of the two side edges 3.3 respectively. During the lifting process, the two front transmission grooves 3.1 are hooked with the front transmission block 4.21 and lift the front limit block 4.2 to make the front limit block 4.2 leave the front limit groove 1.1. At this time, the active slider 3 and the front guide rod 4 form a stable and reliable transmission connection, realizing synchronous movement during the lifting and opening process.

[0055] like Figure 2 、 Figure 4 and Figure 6 ,as well as Figures 7 to 9 As shown, in other embodiments, the limit assembly further includes a rear guide rod 6, which includes a rear base 6.1 transmission-connected to the active slider 3, and a rear limit block 6.2 extending from the rear base 6.1 to the rear end of the carrier 2. The guide rail 1 is provided with a rear limit groove 1.2 for constraining the rear base 6.1 to slide therein. The rear limit groove 1.2 is located below the surface of the opening and closing slide 9 of the guide rail 1. The rear limit groove 1.2 defines a translation stroke in the tilting stroke, and the translation stroke corresponds to the translation section of the track groove 2.1.

[0056] The rear limit block 6.2 is engaged with the rear end of the carrier 2 in the closed position, and limits the forward movement and upward tilting of the carrier 2. The rear base 6.1 is disengaged from the active slider 3 at the end of the translation stroke, and the rear limit block 6.2 is disengaged from the carrier 2 in the opening direction at the end of the translation stroke, allowing the carrier 2 to perform the tilting action.

[0057] Specifically, the rear limit groove 1.2 includes a first groove section 1.21 and a second groove section 1.22 arranged below the first groove section 1.21. The first groove section 1.21 defines a translation stroke. After the active slider 3 drives the rear base 6.1 to move forward and consumes the translation stroke, the rear base 6.1 slides to the second groove section 1.22 and sinks to form a locked limit. At this time, the rear limit block 6.2 separates from the carrier 2 in the opening direction and is away from the tilting stroke of the carrier 2.

[0058] like Figure 13As shown, specifically, the rear guide rod 6 also includes a rear rod body 6.3 connected between the rear base 6.1 and the rear limit block 6.2, and the rod body is set to extend along the length direction of the carrier 2. In this way, the rear end limit of the carrier 2 is controlled by the sliding of the active slider 3, wherein the matching position of the active slider 3 and the rear guide rod 6 is set close to the front end of the carrier 2.

[0059] like Figure 7 As shown, as an embodiment of the transmission between the active slider 3 and the rear base 6.1, the active slider 3 is provided with a rear transmission groove 3.2 which is open away from the opening direction, and the rear base 6.1 is provided with a rear transmission block which is docked with the rear transmission groove 3.2, and the rear transmission groove 3.2 and the rear transmission block are transmission-coordinated through the second inclined surface 7, wherein, by making the cooperation direction of the rear transmission groove 3.2 and the rear transmission block opposite to that of the front transmission groove 3.1 and the front transmission block 4.21, after the translation stroke is consumed, under the action of the locking limit of the rear limit block 6.2 and the rear limit groove 1.2, the rear transmission groove 3.2 and the rear transmission block are forced to disengage from each other, at this time, the rear guide rod 6 is disengaged from the transmission with the active slider 3, and the rear guide rod 6 is retained at the current position after being translated one end distance.

[0060] As a further implementation of the limit locking between the carrier 2 and the rear limit block 6.2, the rear end of the carrier 2 is provided with a hook portion 2.4 extending in the opening direction, and a hook groove 6.21 extending in the opening direction is provided on the rear limit block 6.2. In the closed position, the hook portion 2.4 is placed in the hook groove 6.21, thereby limiting the movement of the carrier 2. After the active slider 3 drives the rear guide rod 6 to translate one end distance, the hook groove 6.21 is translated away from the hook portion 2.4, and at the same time the rear limit block 6.2 is stuck in the rear limit groove 1.2, and the carrier 2 is able to tilt up.

[0061] During the process of returning to the closed position, the carrier 2 sinks as the active slider 3 returns, and the front limit block 4.2 returns to the front limit groove 1.1. As the active slider continues to return, the front transmission groove 3.1 and the front transmission block 4.21 are disengaged under the action of the limit stop.

[0062] At the same time, the hook portion 2.4 on the carrier 2 returns to the opening and closing slide 9 of the guide rail 1. As the active slider 3 returns, the rear transmission groove 3.2 on the active slider 3 again forms a transmission with the rear transmission block on the rear guide rod 6, and drives the rear guide rod 6 to move forward. At this time, the hook groove 6.21 on the rear limit block 6.2 re-engages with the hook portion 2.4 on the carrier 2 to limit the position.

[0063] like Figure 1 and Figure 2As shown, specifically, the active slider 3 is connected to the driving flexible shaft 8, the guide rail 1 includes an opening and closing slide 9, the carrier 2, the active slider 3, the front guide rod 4 and the driving flexible shaft 8 are all arranged to move in the opening and closing slide, and the front guide rod 4 is arranged below the carrier 2. Through this arrangement, the space between the carrier 2 and the opening and closing slide 9 is fully utilized, and the structural compactness of the entire mechanical group is improved under the limitation of a small space, while ensuring the front and rear end limits of the carrier 2 in the closed position.

[0064] Among them, the side of the guide rail 1 corresponding to the opening and closing slide 9 is also provided with a limiting slide 10, and the rear guide rod 6 is arranged to move in the limiting slide 10.

[0065] Specifically, a stop block 9.1 is provided in the opening and closing slide 9, and a buffer block 4.12 is provided on the front base 4.1. The buffer block 4.12 abuts against the stop block 9.1 in the closed position.

[0066] As an explanation of the track groove 2.1 in this embodiment, the track groove 2.1 specifically includes a translation section and a tilting section. In the closed position, the translation section is set in a posture close to horizontal. Its purpose is that when the tilting action is ready to be performed in the closed position, the active slider 3 drives the carrier 2 to translate backward for a certain distance to prevent the panel on the carrier 2 from directly tilting and interfering with the roof. The tilting section is a sunken area in the closed position, and the active slider 3 is constrained in the guide rail 1 and the height of the active slider 3 is fixed. Therefore, when the active slider 3 slides to the tilting section, the carrier 2 is forced to tilt. At this time, the position of the tilting section begins to move upward until the active slider 3 moves to the end of the tilting section.

[0067] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
