Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a skylight U-shaped beam structure. Background Art

[0002] A car sunroof is a window installed on the roof of a car, primarily used to increase ventilation and lighting inside the vehicle, and enhance the passenger experience. Sunroofs can be divided into several types: sliding sunroofs, tilting sunroofs, panoramic sunroofs, and electric sunroofs. However, a technical flaw exists: the sunroof beam is actually an injection-molded product, which is prone to deformation due to internal stress and thermal expansion and contraction.

[0003] Therefore, how to design a skylight U-beam structure becomes a problem that needs to be solved urgently. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a skylight U-shaped beam structure to solve at least one of the above technical problems.

[0005] The technical solution of the utility model is: a skylight U-shaped beam structure, including a beam body, the beam body is pre-deformed into a U-shaped structure, any cross section of the U-shaped structure is a U-shaped shell opening downward, a plurality of staggered circular ribs are arranged in the U-shaped shell, and reinforcing ribs are provided on the closed end of the U-shaped shell, and the reinforcing ribs are arranged along the U-shaped structure.

[0006] The utility model adopts the pre-deformation of the beam body into a U-shaped structure, and the deformation tolerance value is within the allowable range, which solves the technical problem that the actual injection-molded skylight beam product is easily deformed due to internal stress and thermal expansion and contraction. It can be produced in large quantities at one time, and the heavy workload of manual repair is solved; a plurality of staggered circular ribs are arranged in the U-shaped shell to strengthen the structural strength of the skylight U-shaped beam.

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] See Figure 1-3The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read. They are not used to limit the conditions for the implementation of this utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by this utility model without affecting the efficacy and purpose that can be achieved by this utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description and are not used to limit the scope of the implementation of this utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of this utility model without substantially changing the technical content.

[0013] Example 1: A skylight U-beam structure, referring to Figure 1 、 Figure 2 , including a beam body, the beam body is pre-deformed into a U-shaped structure, the two side ends of the U-shaped structure are pre-deformed by 1.5mm in the Y direction, 2mm in the middle along the Z direction, and 1.5mm in the X direction, and any cross section of the U-shaped structure is a U-shaped shell with an opening downward, and a plurality of staggered circular ribs 3 are provided in the U-shaped shell, and a reinforcing rib 4 is provided on the closed end of the U-shaped shell, and the reinforcing rib 4 is arranged along the U-shaped structure. The utility model adopts the method of pre-deforming the beam body into a U-shaped structure, and the deformation tolerance value is within the allowable range, which solves the technical problem that the actual injection-molded products of the skylight beam are easily deformed due to internal stress and thermal expansion and contraction. It can be produced in large quantities at one time, and the heavy workload of manual editing is solved; the structural strength of the skylight U-shaped beam is strengthened by providing a plurality of staggered circular ribs in the U-shaped shell.

[0014] Embodiment 2: Based on embodiment 1, a plurality of circular ribs 3 are staggered along the inner walls of the two straight plates of the U-shaped shell. The utility model adopts staggered arrangement of circular ribs along the inner walls of the two straight plates of the U-shaped shell, thereby strengthening the structural strength of the skylight U-shaped beam.

[0015] Embodiment 3: Based on embodiment 1, adjacent circular ribs 3 are connected by second straight ribs. The utility model connects adjacent circular ribs into one piece by second straight ribs, thereby strengthening the structural strength of the skylight U-beam.

[0016] Example 4: Based on Example 1, the U-shaped structure is provided with a first straight rib 1 and a buckle 2 at the pre-deformed connection. The present invention uses the first straight rib and the buckle to limit the pre-deformed connection of the product, so that the deformation tolerance value is within the allowable range.

[0017] Example 5: Based on Example 1, refer to Figure 3The open ends of the U-shaped structure are each arcuate, forming a downward-opening V-shaped structure. The closed end of the V-shaped structure is provided with an arcuate transition section. Hole positions 5 are provided on the side of the V-shaped structure away from the bottom plate of the U-shaped structure. Hole positions 5 are semicircular. The present invention utilizes arcuate sections of the downward-opening V-shaped structure and semicircular hole positions to meet the structural requirements for installing a skylight U-shaped beam.
