[0003] The front tilting mechanisms of existing top-mounted externally sliding panoramic sunroofs generally have problems such as unstable support strength, complex manufacturing processes, and poor matching consistency with mating parts during operation, which easily cause the failure of a single part and affect the service performance of the entire sunroof. Summary of the Invention

[0004] The purpose of the utility model is to address the deficiencies of the above technologies by providing a front tilting mechanism for a top-mounted externally sliding panoramic sunroof, which can effectively connect the slide rail and the driving slider and is convenient for installation, disassembly, and maintenance.

[0005] To achieve the above objective, the front tilting mechanism of the top-mounted externally sliding panoramic sunroof designed by the utility model includes a front frame provided with a front slide rail, and also includes a front tilting arm that slides through the front slide rail. The front end of the front frame is provided with a front turning chute assembly. The front turning chute assembly is provided with a front turning chute that cooperates with the front slide rail, and when the front tilting arm slides from the front end to the rear end of the front turning chute, it gradually rises. In addition, it also includes a glass skeleton and a driving slider that drives the front tilting arm to move back and forth. The front end of the glass skeleton is hinged and installed on the front tilting arm through a front connecting arm.

Detailed implementation manners

[0025] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] As Figures 1 to 8 shown, a front tilting mechanism for a top-mounted external sliding panoramic sunroof of the present utility model includes a front frame 2 provided with a front slide rail 1, and further includes a front tilting arm 5 that slides through the front slide rail 1. The front end of the front frame 2 is provided with a front turning chute assembly 7. The front turning chute assembly 7 is provided with a front turning chute 8 that cooperates with the front slide rail 1. When the front tilting arm 5 slides from the front end to the rear end of the front turning chute 8, it gradually rises. In addition, it further includes a glass frame 11 and a driving slider 12 that drives the front tilting arm 5 to move back and forth. The front end of the glass frame 11 is hinged and installed on the front tilting arm 5 through a front connecting arm 13.

[0027] Among them, as Figures 6 to 8 shown, the front turning chute assembly 7 includes symmetric first front turning chute fasteners 15 and second front turning chute fasteners 16. The first front turning chute fastener 15 and the second front turning chute fastener 16 are buckled to form the front turning chute assembly 7. During use, it can double support the front tilting arm 5, making the force on both sides uniform and stable.

[0028] In addition, the inner sides of both the first front turning chute fastener 15 and the second front turning chute fastener 16 are provided with a front turning chute 8. One end of the first front turning chute fastener 15 is provided with a male plug 17 inward, and the other end is provided with a female plug 18 inward. The second front turning chute fastener 16 is respectively provided with a matching female plug 18 and male plug 17 at positions corresponding to the male plug 17 and the female plug 18 on the first front turning chute fastener 15, which better realizes the installation and disassembly of the front turning chute assembly 7, and further facilitates the installation, disassembly, and maintenance of the overall structure.

[0029] In this embodiment, each of the left and right sides of the front tilting arm 5 is provided with a mounting post 19. The mounting posts 19 are both provided with front sliding sleeves 20. The front sliding sleeves 20 are located in the front turning chute 8 or the front slide rail 1, which is convenient for reducing the friction force received by the front tilting arm 5 during movement and avoiding affecting its function.

[0030] In this embodiment, there are two first mounting holes 21 on the front connecting arm 13 for fixedly mounting it on the glass framework 11. There is one first hinge hole 22 on each of the front tilting arm 5 and the front connecting arm 13. The front connecting arm 13 is hinged to the front tilting arm 5 through a rivet 23 passing through the first hinge hole 22. On both sides of the first hinge hole 22 on the front tilting arm 5, there is a front tilting arm gasket 24 and a front connecting arm gasket 25 respectively, which facilitates installation, disassembly and maintenance.

[0031] When this embodiment is in use, as Figure 1 shown, in the initial state, the skylight is in the closed state. At this time, the front sliding sleeve 20 of the front tilting arm 5 is at the low point of the front turning chute 8 in the front turning chute assembly 7. When the skylight needs to be opened, as Figure 2 shown, the driving slider 12 drives the front tilting arm 5 to move. Under the action of the front turning chute 8, the front tilting arm 5 gradually rises, so that the skylight glass tilts up. The driving slider 12 continues to move, as Figure 3 shown, to realize the opening of the skylight.

[0032] Similarly, when the skylight needs to be closed, the driving slider 12 drives the front tilting arm 5 to move in the reverse direction, driving the glass to return to its original position first. The driving slider 12 continues to move, and the front tilting arm 5 gradually descends under the action of the front turning chute 8. Finally, the closing of the entire glass is realized.

[0033] For the front tilting mechanism of the top-mounted external sliding panoramic skylight of the present utility model, the front turning chute assembly 7 adopts a double-support structure, with uniform and stable force on both sides, which can better absorb the impact strength of the mechanical group during the actuation process, avoid excessive local force, resulting in an increase in frictional resistance and affecting other functions. The stable actuation force can meet the requirements of repeated reciprocating actuation for opening and closing the skylight; the structural strength is optimized more reasonably, and the product assembly process is set more efficiently, which can meet the requirements of design and production.

[0034] The above shows and describes the basic principles and main structural features of the present utility model. The present utility model is not limited by the above examples. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
