Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile sunroof components, and in particular relates to a sunroof sunshade curtain. Background Art
[0002] Currently, many mid-range and high-end cars are equipped with sunroofs, of which the sunshade, windshield, mechanical assembly, frame, motor (only included in electric sunroofs) and glass are the important components of conventional panoramic sunroofs. The sunshades equipped on different models vary in form, but the basic structure is similar, mainly including sunshade handles, tape, sliders, curtains, springs, reels and installation and fixing structures (such as Figure 1 ); One end of the curtain is fixed to the reel, allowing the curtain to be opened or rolled up around the reel. The reel is fixed to the upper fixed end of the sunroof frame through a fixing seat; the other end of the curtain is fixed to the sunshade handle. The two sides of the sunshade handle are connected to the guide rails through left and right sliders, so that the handle can only slide along the guide rails. The sunshade handle is driven manually or electrically. When the sunshade handle moves away from the reel, the sunshade is closed. When the sunshade handle slides toward the reel, the sunshade is opened. In addition, the electric sunshade is equipped with a motor, zipper and other driving structures. The sunshade is opened and closed by controlling the forward and reverse rotation of the motor to drive the sunshade.
[0003] In the prior art, the sunshade handle is a closed or semi-closed pipe fitting, which requires a large layout space. The slider and the sunshade handle are connected in a sampling plug-in manner, which has poor stability. Summary of the Invention
[0004] The purpose of the utility model is to solve the above technical problems and provide a skylight sunshade with high stability.
[0005] To achieve the above-mentioned purpose, the utility model provides a sunroof sunshade, including a sunshade handle and sliders installed at both ends of the sunshade handle; the cross-section of the sunshade handle is a double-hole structure, one side of the thin steel plate is folded inward to form a large hole, and the other side is folded inward to form a small hole; correspondingly, the slider includes a slider body, and a small plug-in part and a large plug-in part arranged side by side at the end of the slider body; the small plug-in part is clamped in the small hole of the sunshade handle, and the large plug-in part is clamped in the large hole of the sunshade handle.
[0006] Furthermore, the bottom surface and outer side surface of the large plug-in portion are both provided with elastic protrusions, and the bottom surface of the small plug-in portion is also provided with elastic protrusions; the three elastic protrusions are respectively interference fit with the bottom surface and side edge of the sunshade handle.
[0007] Furthermore, the inner side surfaces of the large plug-in portion and the small plug-in portion are both arranged with Z-direction stops that play a guiding role when the slider is assembled with the sunshade curtain handle.
[0008] Furthermore, the thickness of the small hole of the sunshade curtain handle is smaller than the thickness of the large hole.
[0009] Furthermore, the cross section of the elastic protrusion is an arched narrow sheet structure.
[0010] Compared with the existing technology, the beneficial effects of the present invention are: the double-hole sunshade handle of the present invention can adapt to a narrower space layout, reduce materials and lower costs; the sunshade handle is combined with the slider, which is easy to install and has stronger anti-torsion ability. The connecting parts are matched through elastic snap-in features, which can ensure that the entire system has a more stable structure due to high and low temperature changes or when passing through bumpy roads. The snap-in force between the sunshade handle and the slider can effectively eliminate the risks of vibration and abnormal noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] like Figure 2 、 3 The sunroof sunshade comprises a sunshade handle 1 and sliders 2 mounted at both ends of the sunshade handle 1. The sunshade handle 1 has a double-hole cross-section, with one side of the thin steel sheet folded inward to form a large hole 1.2, and the other side folded inward to form a small hole 1.1. Correspondingly, the slider 2 comprises a slider body 2.1, and a small plug-in portion 2.2 and a large plug-in portion 2.3 arranged side by side at the ends of the slider body 2.1. The small plug-in portion 2.2 snaps into the small hole 1.1 of the sunshade handle 1, and the large plug-in portion 2.3 snaps into the large hole 1.2 of the sunshade handle 1.
[0019] The bottom and outer side of the large plug part 2.3 are arranged with elastic protrusions 2.4. Similarly, the bottom surface of the small plug part 2.2 is also arranged with elastic protrusions 2.4. After the sunshade handle 1 and the slider 2 are assembled, the AA section is as follows: Figure 5 As shown, the cross section of the elastic protrusion 2.4 is as follows Figure 6 The structure shown is an arched narrow sheet. The elastic protrusion 2.4 is elastically deformed during assembly and interference-fitted into the sunshade handle, increasing the friction between the slider and the sunshade handle and maintaining uniform force. After assembly, the three elastic protrusions are interference-fitted with the bottom and side of the sunshade handle respectively. While ensuring interference fit, the insertion and removal force will not be too large. On the one hand, it meets the stability requirement that the two are not easy to fall off. On the other hand, it also ensures that the slider has a certain fine-tuning ability in the axial direction of the sunshade handle to avoid jamming in moving conditions such as bumpy roads. The slider of the utility model can adaptively change its shape by compression, increase the friction between the slider and the sunshade handle, maintain uniform force, and meet different moving conditions at the same time.
[0020] In addition, the inner sides of the large plug-in part 2.3 and the small plug-in part 2.2 are both arranged with Z-direction stops 2.5. The Z-direction stops play a guiding role when the slider and the sunshade handle are assembled, and further limit the displacement and rotation of the slider in the sunshade handle to ensure assembly stability.
[0021] When the slider of this utility model is inserted into the sunshade handle, the slider's large plug-in section guides and self-aligns, making it easier to ensure component alignment during assembly. The small plug-in section prevents the large plug-in section from rotating or shifting during use, effectively enhancing the slider's torsional resistance and preventing it from deforming when subjected to torsional forces. The assembly of the slider and sunshade handle ensures more uniform force transmission, reduces localized force concentration, extends the product's service life, and reduces the risk of breakage.
[0022] The small hole of the sunshade handle in this utility model is thinner than the large hole, which can adapt to the layout of narrower spaces. At the same time, the cross-sectional contact area of the sunshade handle is increased, which can resist shear force and lateral force, and effectively improve the stability of the connection.
[0023] Compared with the sunshade handle in the prior art, the double-hole sunshade handle of the present invention can adapt to a narrower space layout, reduce materials and lower costs; the sunshade handle is combined with the slider, which is easy to install and has stronger torsion resistance. The connecting parts are matched through elastic snap-fit features to ensure that the entire system has a more stable structure due to high and low temperature changes or when passing through bumpy roads. The snap-fit force between the sunshade handle and the slider can effectively eliminate the risks of vibration and abnormal noise.
