Description

Technical Field

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

[0002] With the increasing use of private cars, the number of car accessories is also increasing. In summer, the amount of solar radiation is high, and strong sunlight can shine into the car through the sunroof, affecting both the driver's driving and the interior temperature, causing discomfort to passengers. Current technology addresses the problem of strong sunlight shining through the sunroof of private cars by designing sliding sunshades to block it.

[0003] Sliding sunroof sun visors are a common design in automobiles. Their structure mainly includes the sun visor body, the sun visor sliding bracket, and the handle mechanism. The sun visor sliding bracket is slidably connected to the slide rail mechanism. Due to the elastic support feet of the sliding bracket (usually plastic or metal springs) undergoing elastic fatigue, wear, or deformation after long-term use, the contact with the slide rail becomes unstable, resulting in shaking or jamming.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 This utility model provides a technical solution: a car sunroof sunshade, including a light-shielding plate 3, a sound-insulating plate 2, and a base plate 1, which are fixedly connected from top to bottom. Two guide brackets 5 are provided on both sides of the base plate 1. The guide bracket 5 includes a U-shaped support frame 51 fixedly installed on the side wall of the base plate 1 and two elastic support legs 52 fixed to the end of the U-shaped support frame 51. An elastic traction component 6 for providing tensile force is provided between the two elastic support legs 52.

[0025] By setting an elastic traction component 6 between two elastic legs 52 of the same guide bracket 5, when the elastic leg 52 itself has insufficient resilience, the elastic traction component 6 actively enhances the resilience and stability of the elastic leg 52, so that the elastic leg 52 can fully slide and contact the inner wall of the guide rail 9, increasing the contact area and ensuring that the sunshade is pushed and pulled stably and smoothly; it can significantly reduce the shaking and jamming problems during the sliding process of the sunshade, and improve the smoothness and durability of use.

[0026] like Figure 5 The diagram shows the cooperation structure of a guide bracket 5 and a guide rail 9. In fact, there are two guide rails 9, which are symmetrically distributed, with two guide brackets 5 on the same side cooperating with one guide rail 9.

[0027] It should be noted that the sound insulation panel 2 is made of polyurethane foam, which has a porous structure to absorb sound waves. Its lightweight structure absorbs wind noise and reduces vibration transmission. The light-shielding panel 3 is made of aluminum honeycomb composite panel, which is lightweight, has strong resistance to deformation, and good temperature resistance. The bottom of the substrate 1 also needs to be wrapped with a layer of knitted fabric to improve the comfort of users when in contact with it. The above materials are common knowledge to those skilled in the art.

[0028] See Figure 4 The elastic traction component 6 includes a central block 62 fixed to the end of the U-shaped support frame 51 and a positioning block 61 fixed to the end of each elastic support leg 52. A spring 63 is fixedly connected between each positioning block 61 and the central block 62.

[0029] The end of the elastic support leg 52 has a certain bending elasticity with the U-shaped support frame 51, so that the other end of the elastic support leg 52 can contact the inner wall of the guide rail 9. However, after long-term use, elastic fatigue will occur. At this time, by adding a spring 63, the elastic support leg 52 is further pulled so that the elastic support leg 52 can fully contact the inner wall of the guide rail 9.

[0030] See Figure 2 and Figure 4 A screw hole 102 is provided on the side wall of the substrate 1. The U-shaped support frame 51 is fixedly installed on the side wall of the substrate 1 by bolts 7, and the threaded end of the bolt 7 is screwed into the screw hole 102.

[0031] The purpose of fixing the guide bracket 5 to the side wall of the base plate 1 is to enable the entire sunshade to slide inside the guide rail 9 via the guide bracket 5. When a single guide bracket 5 is damaged, it can also be disassembled and replaced individually.

[0032] See Figure 1 The top of the substrate 1 has a groove 101, and the sound insulation plate 2 and the light shield 3 are fixedly embedded in the groove 101 in sequence.

[0033] The dimensions of the sound insulation board 2 and the light shield 3 are adapted to the inside of the groove 101. During installation, the groove 101 is vertically aligned, and the sound insulation board 2 and the light shield 3 are pressed into the groove in sequence. The sound insulation board 2, the light shield 3, and the groove 101 are all bonded to each other with epoxy structural adhesive, which has ultra-high strength and is resistant to aging.

[0034] See Figure 1 The light-shielding plate 3, the sound-insulating plate 2, and the substrate 1 are all provided with through mounting holes 8. Multiple mounting holes 8 are fitted with an embedded handle 4. The lower end of the embedded handle 4 extends to the bottom of the substrate 1.

[0035] The embedded handle 4 provides a force fulcrum and transmits human pulling force. That is, by pushing and pulling the embedded handle 4, the sun visor can move linearly along the guide rail 9, thereby achieving the sunshade function for passengers and drivers inside the car. Similarly, epoxy structural adhesive is injected into the gap between the embedded handle 4 and the mounting port 8 to increase the installation strength and prevent it from falling off.

[0036] See Figure 2 and Figure 3 There are four guide brackets 5, with two of them set on one side of the base plate 1.

[0037] The four guide brackets 5 form a rectangular stable structure, which balances the force, reduces lateral swaying, prevents the sunshade from getting stuck, and helps to move smoothly. Each bracket bears the weight of the sunshade, ensuring uniform force distribution and avoiding deformation of the guide bracket 5 or breakage of the base plate 1 due to excessive force at a single point.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
