DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0031] Example 1.

[0032] like Figure 1-8 As shown, the lightweight sun visor described in this embodiment includes:

[0033] Sun visor body 1;

[0034] A rotating shaft seat 2, wherein the rotating shaft seat 2 is fixedly connected to the vehicle body;

[0035] A rotating shaft 3, one end of which is rotatably connected to the rotating shaft seat 2;

[0036] A pulling mechanism 4, which is installed on one side of the sun visor and slidably cooperates with the rotating shaft 3, and is configured to rotate along the axis of the rotating shaft 3 together with the sun visor body 1 under the action of an external force, or to move away from / approach the rotating shaft seat 2 along the axial direction of the rotating shaft 3;

[0037] The pulling mechanism 4 includes a guide tube 41, a slide seat 42 and a retaining spring 43 embedded in the surface of the slide seat 42. The guide tube 41 is fixedly installed on one side of the sun visor. The slide seat 42 is arranged in the guide tube 41 and slidably cooperates with the inner wall of the guide tube 41. The slide seat 42 is provided with a groove 421 for accommodating the retaining spring 43 and a shaft hole 422 connected to the groove 421. The end of the shaft 3 away from the shaft seat 2 extends into the guide tube 41 and passes through the shaft hole 422 to be placed in the groove 421. The circumferential surface of the shaft 3 placed in the groove 421 is provided with a first flat surface 31 that cooperates with the retaining spring 43. In specific implementation, as Figure 3 , Figure 4 and Figure 6As shown, the shaft seat 2 is fixed on the top of the vehicle body. Generally, the sun visor body 1 is maintained in a retracted state by the pulling mechanism 4. In this state, the sun visor body 1 is close to the roof of the vehicle, and the shaft 3 is elastically clamped by the clip 43 to keep its position stable. When the user needs to shade the sun, he only needs to manually flip the sun visor body 1 downward. At this time, the sun visor body 1 will rotate along the shaft 3. This rotation action is controlled by the pulling structure 4. During the rotation process, the clip 43 is elastically deformed in the groove 421. Then, when the external force is released, the clip 43 returns to its original position and clamps the shaft 3, so that the sun visor body 1 can be stabilized at the position set by the user; in addition, if the user wants to adjust the sun visor body 1 The sun visor body 1 can be adjusted by manually pulling or pushing the sun visor body 1. This action will cause the sun visor body 1 and the guide tube 41 to slide relative to the slide seat 42, so that the sun visor body 1 moves away from or close to the shaft seat 2 along the axis of the shaft 3, and the function of adjusting the sun visor position is achieved. This design allows users to adjust the sun visor at multiple angles and distances according to personal needs. It not only achieves the sunshade function, but also looks beautiful, greatly improving the driving experience.

[0038] In some embodiments, Figure 4 and Figure 5 As shown, in order to ensure the stability of the sun visor body 1 in the pulling and pulling action, the surface of the guide tube 41 is provided with a second flat surface 411 arranged along its length direction, and the surface of the slide seat 42 opposite to the inner wall of the guide tube 41 is provided with a plurality of guide ribs 44 at intervals, and the slide seat 42 slides with the inner wall of the guide tube 41 through each guide rib 44. With this structural design, the guide tube 41 is not just a simple circular pipe, but is provided with a second flat surface 411 along the length direction on its inner wall, the purpose is to cooperate with the action of the slide seat 42 to avoid twisting when the two slide and cooperate and avoid deviation from the predetermined sliding trajectory. At the same time, the existence of the guide rib 44 can produce a better sliding cooperation effect between the slide seat 42 and the inner wall of the guide tube 41, so that when the sun visor body 1 is pulled and pulled, its stability is greatly enhanced. In addition, in this embodiment, the guide tube 41 is an aluminum tube to meet the design requirements of lightweight sun visor.

[0039] Further, such as Figure 5 As shown, the surface of the slide 42 opposite to the inner wall of the guide tube 41 is also provided with a receiving groove, and a positioning block 45 is connected to the receiving groove through a spring, and the positioning block 45 abuts against the inner wall of the guide tube 41. In this way, during the sliding process of the slide 42, the spring and the positioning block 45 can always maintain effective contact with the inner wall of the guide tube 41, that is, the spring is used to provide a certain buffer and elasticity to ensure that the slide 42 will not swing or deflect excessively during the movement of the slide 42 in the guide tube 41.

[0040] In some embodiments, Figure 2 and Figure 5 As shown, the openings at both ends of the guide tube 41 are respectively equipped with a first end cap 5 and a second end cap 6 (flat thread interference fit), the first end cap 5 is connected to the sun visor body 1 through a snap-fit ​​structure 51, and the first end cap 5 is provided with a through hole for the shaft 3 to pass through; the second end cap 6 is integrally formed with the sun visor body 1. In this embodiment, the first end cap 5 is connected to the sun visor body 1 through the snap-fit ​​structure 51, and this design not only facilitates the combination of the end cap and the sun visor, but also facilitates the disassembly and maintenance of each component, and the second end cap 6 is integrally formed with the sun visor body 1. This integrally formed design makes the sun visor more compact and stable, and the combination of the two not only makes the sun visor look more neat and beautiful, but more importantly, during use, whether it is the rotation and opening and closing of the sun visor body 1 relative to the shaft 3, or moving away from or approaching the shaft seat 2 along the axis of the shaft 3, it can be carried out smoothly, which undoubtedly increases the use experience of the sun visor.

[0041] In some embodiments, Figure 2 and Figure 7 As shown, for positioning and stability, the slide 42 is symmetrically provided with a pair of elastic positioning arms 7 on one side facing the second end cover 6, and the free ends of the elastic positioning arms 7 are symmetrically provided with arc-shaped positioning protrusions 71; the inner wall of the second end cover 6 is correspondingly provided with a positioning hole 61 opening toward the slide 42, and the inner wall of the positioning hole 61 is provided with a limiting groove 62 adapted to the positioning protrusion 71. With this structural design, when the guide tube 41 slides relative to the slide 42, the elastic positioning arm 7 cooperates with the positioning hole 61 to ensure accurate positioning during the resetting of the pulling action, and prevents unnecessary shaking and swinging, while the cooperation between the arc-shaped positioning protrusion 71 and the limiting groove 62 provides a fixed point, so that the sun visor body 1 can maintain stability under the vibration generated during the driving of the vehicle, and avoids possible interference and abnormal noise of components.

[0042] In some embodiments, Figure 1 , Figure 2 and Figure 8As shown, in order to achieve a higher degree of structural integration, a makeup mirror assembly 8 is also included, and the makeup mirror assembly 8 is embedded on the plate surface of the sun visor body 1, and a power supply contact 63 electrically connected to the makeup mirror assembly 8 is arranged on the surface of the second end cover 6 relative to the slide seat 42, and the rotating shaft 3 is a hollow structure and a power supply wiring harness electrically connected to the vehicle power supply is passed through it, and one end of the rotating shaft 3 located in the groove 421 is fixedly connected to a power supply contact 9 electrically connected to the power supply wiring harness, and the power supply contact 9 protrudes from the surface of the slide seat 42 and is located on the rotation trajectory of the power supply contact 63. In this embodiment, the makeup mirror assembly 8 is embedded on the plate surface of the sun visor body 1, realizing the diversified functions of the sun visor and facilitating the use needs of the driver and passengers in the car, and a power supply contact 63 electrically connected to the makeup mirror assembly 8 is provided on the surface of the second end cover 6 relative to the slide seat 42, and one end of the rotating shaft 3 located in the groove 421 is fixedly connected to a power supply contact 9 electrically connected to the power supply wiring harness, and the power supply contact 9 protrudes out of the surface of the slide seat 42 and is located on the rotation track of the power supply contact 63, so that no matter how the sun visor rotates, the power supply contact 9 can contact the power supply contact 63, thereby ensuring the power supply of the makeup mirror assembly 8.

[0043] Specifically, if Figure 2 and Figure 8 As shown, the power supply contact piece 63 is two metal spring pieces that are arranged opposite to each other and tend to be retracted inwards; a plastic positioning piece 91 is embedded in one end of the rotating shaft 3 away from the rotating shaft seat 2, and a through hole is provided on the sliding seat 42 for the plastic positioning piece 91 to be inserted. The end of one end of the plastic positioning piece 91 that passes through the through hole is a plug-in section 92, which is embedded between the two power supply contact pieces 63, and the outer peripheral surface of the plug-in section 92 is convexly provided with a plurality of metal ridges 93 along its axial direction, and the metal ridges 93 are electrically connected to the power supply harness, and are exposed from the plug-in section 92 to form a power supply contact 9. In this embodiment, the power supply contact piece 63 is two metal spring pieces that are arranged opposite to each other and tend to be retracted inwards. This design allows a good electrical connection to be formed when the plug section 92 is inserted, and the connection will not be lost during the rotation of the sun visor body 1. The outer peripheral surface of the plug section 92 is provided with metal ridges 93, which are electrically connected to the power supply harness and exposed outside the plug section 92 to form power supply contacts 9. Figure 7 As shown, when the sun visor body 1 is flipped to a specific angle (for example, the sun visor body 1 is in the unfolded state), the power contact 9 can always maintain a good electrical connection with the power contact piece 63, thereby continuously providing power to the makeup mirror assembly 8. In addition, when the sun visor body 1 is flipped to the top storage state, the power contact 9 is staggered from the power contact piece 63, and the power contact piece 63 will abut against the plug-in section 92 at the end of the plastic positioning piece 91. At this time, the power supply of the makeup mirror assembly 8 is cut off. This design realizes intelligent management of power supply, saves power consumption, and improves safety of use.

[0044] In some embodiments, Figure 2 As shown, in order to simply and effectively meet the lightweight design requirements, the sun visor body 1 is made of two upper and lower EPP plates 11 heat-sealed together, an injection-molded skeleton 12 is sandwiched between the two EPP plates 11, and the outer surfaces of the two EPP plates 11 are heat-bonded with a first fabric 13; the sun visor body 1 is provided with a mounting groove that matches the shape of the makeup mirror assembly 8. In specific implementation, the first fabric 13 can be heat-laminated on the surface of two pre-prepared EPP sheets 11, and then the two EPP sheets 11 are compositely clamped with the injection molded skeleton 12. This lightweight design not only ensures appropriate strength, but also reduces the total weight, which meets the needs of lightweight design. In this embodiment, the injection molded skeleton 12 will be embedded with a steel wire skeleton during injection molding and then injection molded to improve the rigidity of the sun plate body 1 so that it is not easy to deform during use, and the first fabric 13 covering the surface makes its surface more beautiful and textured. In addition, the installation groove that matches the shape of the makeup mirror assembly 8 not only simplifies the installation steps, but also ensures the close fit between the makeup mirror assembly 8 and the sun visor body 1, avoids the influence of the gap on the light inside the car, and improves the overall aesthetics. In this embodiment, the composite surface of the first fabric 13 is compounded with 30-40 g / m2 spunlace non-woven fabric and 60-80 g / m2 hot-melt adhesive felt in sequence. The addition of the non-woven fabric can prevent the first fabric 13 from changing color due to excessive temperature during compounding. Due to the high temperature and the structural characteristics of the first fabric 13, the glue of the hot-melt adhesive felt will overflow from the surface of the fabric, resulting in poor appearance. The addition of the non-woven fabric can also avoid this problem.

[0045] In some embodiments, Figure 2 As shown, the vanity mirror assembly 8 includes a mirror body 81 and a mirror cover 82. The mirror body 81 is symmetrically provided with a plurality of locking pins 83 on the back, and the inner wall of the mounting groove is correspondingly provided with a locking slot adapted to the locking pins 83. The mirror cover 82 is made of a second fabric coated with a resin plate by hot pressing and compounding, and a magnet for triggering the opening and closing of the magnetic control circuit board in the mirror body 81 is embedded in the mirror cover 82. In this embodiment, the mirror body 81 is symmetrically provided with a plurality of locking pins 83 on the back to buckle with the locking slot adapted to the inner wall of the mounting groove, so that the mirror body 81 can be stably fixed in the sun visor, greatly reducing the possibility of shaking or falling off of the vanity mirror assembly during vehicle driving. In addition, the mirror cover 82 is made of a resin plate covered by a second fabric by hot pressing. This design not only ensures the hardness of the mirror cover, but also ensures its soft touch. The mirror cover 82 is embedded with a magnet that can trigger the opening and closing of the magnetic control circuit board in the mirror body 81. When the mirror cover is opened or closed, the magnetic control circuit can sense the increased or decreased magnetic field to respond, thereby automatically controlling the on and off of the built-in light, realizing intelligent power management. In this embodiment, if Figure 2As shown, a plurality of resin plates covering the mirror cover 82 with the second fabric can be arranged at intervals along the width direction of the mirror body 81, so that when the mirror cover 82 is opened, the area corresponding to one or more resin plates can be selectively opened, so that the user can choose the area to open according to needs.

[0046] The lightweight sun visor provided in this embodiment has a pull-out structure added to the structural design to easily pull out the sun visor, thereby adjusting the shading position, and is easy to operate. The sun visor is made of lightweight materials such as EPP, which not only reduces the weight and facilitates manual pulling, but also can be designed in a larger size to form a large effective shading area. At the same time, the appearance design is beautiful and atmospheric, which improves the visual comfort in the car.
