Description

Technical Field

[0001] This utility model relates to the field of automotive sunroof sunshade technology, specifically a clip for automotive sunroof sunshade. Background Technology

[0002] A sunroof is a feature on cars, essentially a sunroof of maximum size. The glass is exceptionally large, allowing excellent natural light into the car, but in summer, the intense sunlight can cause the interior to overheat. Therefore, a sunroof sunshade was developed. It consists of a layer of light-blocking fabric sewn onto a wire loop and secured to the opening in the sunroof roof using clips.

[0003] Existing card structures, such as Figure 1 As shown, because there are upper and lower arms, the thickness cannot be too thin. The gap between the skylight and the skylight glass is very small: 3-5mm, so it is difficult to implement a design with upper and lower arms. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model proposes to provide a clip for car sunshade curtains, which has a more symmetrical structure and more balanced force distribution.

[0005] A clip for a car sunroof sunshade includes a clip body and a magnet. The clip body includes:

[0006] The middle support section has its bottom contacting the edge of the skylight and its top suspended.

[0007] An inner support arm is located between the ceiling and the glass, with its end in contact with the glass and its root connected to the intermediate support portion.

[0008] An outer support arm, which is located below the glass, with its end in contact with the glass and its root connected to the middle support portion;

[0009] Anti-detachment part, the anti-detachment part is located at the root of the inner support arm;

[0010] The magnet mounting part is located at the root of the outer support arm and has a magnet mounting position for mounting magnets.

[0011] Furthermore, the vertical dimension of the magnet mounting part is greater than the gap between the skylight and the canopy glass.

[0012] Furthermore, the magnet mounting part is also provided with a magnetic guide bracket.

[0013] Furthermore, the magnetic guide bracket is U-shaped, with the middle part located above the magnet or on the side near the ceiling, in contact with one magnetic pole of the magnet, and the two sides bent towards the other magnetic pole.

[0014] Furthermore, the inner support arm is perpendicular to the edge of the skylight.

[0015] Furthermore, the outer support arm is an injection-molded structure.

[0016] Furthermore, the outer support arm comprises an elastically deformable material.

[0017] Furthermore, the elastic deformation material is spring steel wire.

[0018] Furthermore, the magnetic poles of the magnet mounting portion are oriented vertically.

[0019] Furthermore, the magnetic poles of the magnet mounting portion are in the horizontal direction.

[0020] Compared with existing technologies, the inner support arm of this utility model, concealed between the ceiling and the glass, and the exposed outer support arm, are both perpendicular to the edge of the skylight. In its free state, resembling two upward-curving wings, the inner support arm is forcibly installed through the gap between the ceiling skylight and the glass. This significantly restricts the height of the support arm, generating stress that ensures a tight fit between the support and the ceiling skylight. The anti-detachment feature prevents the clip from coming off on its own. After the sunshade is installed, the clip experiences vertical force. The ceiling skylight applies an upward force to the support, while the skylight glass provides a downward force to both the outer and inner support arms, resulting in a state of force equilibrium for the clip.

[0021] This utility model uses transparent material injection molding for the clip, which avoids the large exposed size due to the outer support arm being perpendicular to the edge of the skylight, especially the large exposed length of the skylight, which makes it more noticeable.

[0022] This invention incorporates pre-embedded elastic deformation materials, such as spring steel wire. Spring steel has a large elastic deformation range and better temperature resistance, resulting in a more robust assembly effect and reducing the likelihood of failure. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0030] like Figure 2-5 As shown, a clip for a car sunroof includes a clip body and a magnet, and may also include a magnetic guide bracket. An inner support arm 32 is concealed between the roof and the glass; an anti-detachment part 34 is located at the base of the inner support arm 32; a middle support part 33 connects to the anti-detachment part 34 and is clipped onto the sunroof window; a magnet mounting part 42 protrudes outside the sunroof window and is located below the support part 33, containing a magnet 41 and a magnetic guide bracket 43; and an outer support arm 31 connects to the magnet mounting part 42, is exposed, and is perpendicular to the edge of the sunroof window.

[0031] Magnet 41, magnetic guide bracket 43, and magnet mounting part 42 together complete the magnetic attraction function and can be collectively referred to as magnetic attraction part 4. When the sunshade is installed, the magnet and magnetic guide bracket attract the steel wire structure of the sunshade.

[0032] Magnets are typically simple in shape, such as cuboids or cylinders, making them prone to detaching when mounted on clips. However, the magnetic guide bracket 43, made of metal, can be designed into more complex shapes, such as a U-shape. The inner width of the U-shape is greater than the size of the magnet 41, so the magnetic guide bracket 43 and the magnet 41, when combined, form an inverted mountain shape. This makes it very easy to install onto the magnet mounting part 42 and prevents it from easily detaching.

[0033] The clip body is manufactured using injection molding. The magnetic poles of the magnet 41 can be vertical, in which case the steel wires of the sunshade are attracted from below.

[0034] The magnetic poles of the magnet 41 can be horizontal, perpendicular to the edge of the skylight, in which case the steel wire of the sunshade is attracted from the inside. The steel wire of the sunshade is usually flat steel wire with a rounded rectangular cross-section, either 6mm×2mm or 3.8×1.4mm, with the longer side of the rectangle being nearly three times the length of the shorter side. At this point, the magnet's attraction area becomes approximately three times its original size. Example 2

[0035] The difference from Embodiment 1 is that the magnetic suction part 4 does not have a magnetic guide bracket 43. In this case, the firmness of the assembly between the magnet 41 and the magnetic guide bracket 43 needs to be fully considered. A method of pre-embedding the magnet during injection molding can be used, or a magnet of a special shape can be used.

[0036] Example 3

[0037] The difference from Embodiment 1 is that the outer support arm 31 and the inner support arm 32 contain metal spring material, and the entire clip body is an injection molded part with a pre-embedded spring.

[0038] The inner support arm 32 and the outer support arm 31 need to have good deformability and be as thin as possible to easily fit into the gap between the skylight and the glass. Although plastic has some elasticity, its low strength requires a large thickness, and its low elasticity makes it unsuitable. Therefore, using metal spring material for the inner support arm 32 and the outer support arm 31 is a better choice.

[0039] For the overall strength of the clip, the middle support part 33 is best integrated with the two support arms, so it is also made of metal spring material.

[0040] In this way, it is equivalent to injection molding a magnet mounting part 42, such as a spring sheet, onto a metal spring.

[0041] The ends of spring sheets are usually quite sharp, so they can be made safer by injection molding a layer of plastic over them.

[0042] The anti-detachment part can be formed directly from spring material or by injection molding.

[0043] Another good solution is to use spring steel wire bent into a closed or semi-closed shape, with the end remaining at the magnet mounting part and encased in injection molding material. This way, only the middle part needs injection molding, as the ends don't have sharp points.

[0044] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
