Description

Technical Field

[0001] This invention relates to a sunroof structure, specifically a high-strength mechanical assembly for a panoramic sunroof. Background Technology

[0002] As times change, automotive safety levels are also gradually increasing. To meet customers' high demands for the stability and safety performance of sunroofs, the internal components need to be strengthened and adjusted accordingly. The most critical component is the mechanical structure of the panoramic sunroof, as it supports the opening and closing of the glass and affects the overall safety of the sunroof. In traditional sunroofs, during the tilting process, the slider's pin is in an inclined slider groove on the support frame. This results in poor sunroof stability during tilting. At high speeds or under the weight of the sunroof glass, the increased noise and load on the tilting motor can easily damage it. Furthermore, when the sunroof is closed or fully open, the corresponding pin is located at the upper or lower end of the slider groove, lacking adequate planar support, which also affects the stability of the sunroof when opening and closing. Summary of the Invention

[0003] This invention provides a high-strength mechanical assembly for panoramic sunroofs that is simple in structure, has a stable and high-strength support structure, and can provide high-strength and stable support under closed, tilted, and fully open conditions.

[0004] The technical solution adopted in this invention is: a high-strength mechanical assembly for a panoramic sunroof, comprising a lifting arm, a front bracket, a rear bracket, a drive block, and a front slider. The front bracket's front end is connected to the front end of the lifting arm via a front connecting pin. Two front bracket sliding feet are provided on the front and rear sides of the front bracket, positioned within the upper sliding groove of the mechanical assembly guide rail. The middle of the front bracket is connected to the front sliding groove of the front slider via a front sliding pin. The front sliding groove is a through-slot structure with the front part raised forward and the rear part horizontal. Two front slider sliding feet are provided on the front and rear sides of the front slider, positioned within the lower sliding groove of the mechanical assembly guide rail. The rear end of the front slider is connected to the front end of a connecting rod via a connecting pin. A connecting rod sliding groove is provided at the rear of the connecting rod. The groove is a through-groove structure with a horizontal front and a raised rear. The connecting rod slide groove is connected to the front end of the rear slider via a middle sliding pin. The front of the rear slider is connected to the drive block placed in the sliding groove of the upper bracket outside the mechanical group guide rail via a connecting port. Two or more rear slider sliding feet are set in the sliding groove of the lower slider outside the mechanical group guide rail on the front and rear sides of the rear slider. The rear slider is provided with a rear slide groove, which is composed of three horizontal sections connected in pairs from front to back. The rear slide groove is connected to the middle of the rear bracket via a rear sliding pin. The front end of the rear bracket is provided with a rear bracket sliding foot placed in the sliding groove of the upper bracket outside the mechanical group guide rail. The rear end of the rear bracket is connected to the rear end of the lifting arm via a rear connecting pin.

[0005] The front part of the lifting arm is provided with a forward-facing front latch, and the front part of the front slider is provided with a rearward-facing front slider stop corresponding to the front latch.

[0006] The rear part of the lifting arm is provided with a rear-facing rear latch, and the rear part of the rear slider is provided with a front-facing rear slider latch corresponding to the rear latch.

[0007] The connecting rod is provided with a connecting rod stop, and the middle part of the lifting arm is provided with a corresponding middle retaining groove facing backward.

[0008] The bracket sliding groove is provided with snap-fit ​​ribs, and the lower end surfaces of the front bracket sliding foot, the drive block, and the rear bracket sliding foot are provided with snap-fit ​​through grooves that cooperate with the snap-fit ​​ribs.

[0009] The front slider foot and the rear slider foot are provided on the inner and outer sides of their respective sliders, and are guided and positioned in the inner and outer slider sliding grooves of the mechanical assembly guide rail.

[0010] Wear-resistant sleeves are fitted onto the front slider foot and the rear slider foot.

[0011] When the mechanical assembly of this invention is in the closed state, the front and rear sliding pins are respectively located at the rear ends of the front and rear slide grooves, while the middle sliding pin is located at the front end of the connecting rod slide groove. At this time, the positions of the three sliding pins and their corresponding slide groove positions are all planar supports, ensuring excellent stability during vibration. The ends of the lifting arm and the rear slider form a rear latch and a rear slider latch, which cooperate with each other. When the skylight bears a force exceeding the material properties of the mechanical assembly itself, sufficient tensile force is provided to prevent material cracking and deformation, allowing the mechanical assembly body to withstand a stronger ejection force and meet the customer's high strength requirements.

[0012] The drive block is inserted into the connection port of the rear slider and installed in the sliding groove of the upper bracket on the outer side of the mechanical assembly guide rail. When the motor pulls the drive block, the rear slider, along with the middle sliding pin, moves backward. Simultaneously, the rear sliding pin moves forward relative to the rear slider in the rear sliding groove. When the rear sliding pin moves to the middle horizontal section of the rear sliding groove for support, the entire mechanical assembly is in a tilting state. At this time, the rear sliding pin and the rear slider are supported by a plane, which ensures excellent stability during tilting vibration. As the drive block continues to move backward, the rear slider drives the front slider via the middle connecting rod, causing the middle sliding pin, the front sliding pin, and the rear sliding pin to slide continuously. When the front sliding pin slides to the top of the front end of the front sliding groove, the front bracket rotates synchronously to its maximum angle. Simultaneously, the middle sliding pin slides to the top of the rear end of the connecting rod groove. Simultaneously, the rear sliding pin slides to the highest horizontal section of the rear sliding groove, at which point the mechanical assembly is in a fully open state. Because the front and middle sliding pins are at the end and top of their respective slides, and the rear sliding pin is also on the horizontal section of the rear slide, the mechanical assembly in the open state maintains very good stability when vibrating due to the support of this plane.

[0013] Meanwhile, to ensure the stability of the mechanical assembly within the sunroof guide rail, sliding foot structures are provided on both the front and rear sliders. These sliding foot structures are inserted into the sliding grooves of the lower outer slider of the mechanical assembly guide rail, preventing it from moving longitudinally, laterally, or vertically; it can only slide along the guide rail's trajectory.
