Description

Technical Field

[0001] The present application relates to the technical field of vehicle interior decoration, and in particular to a novel sun visor with full-angle adaptability and adjustment and a vehicle. Background Art

[0002] When a car is driving, the driver and passengers often face the sun directly, which causes discomfort to their vision. Especially when driving in the direction of the sun suddenly turns to driving against the sun, the driver will be suddenly exposed to strong direct sunlight, and a blind spot will appear in front of his eyes, posing a great safety hazard. Therefore, people set a sun visor on the windshield of the car to meet the driver's and passengers' driving needs for protection and to improve safety and comfort when driving.

[0003] The sun visor is an automotive interior part designed to meet the customer's sunshade requirements. In view of the different fields of view of different vehicles (sedans, SUVs, trucks), as well as the customer's height and driving habits, the sun visor's adjustable shading angle should meet the full-angle field of view adjustment requirements and be fixed at any position that the customer can adapt to. It must also meet the requirements of angle retention and no abnormal noise during driving vibration.

[0004] The existing sun visor is installed on the roof of the car through a rotating shaft seat, and the sun visor is manually flipped to achieve the sunshade function; the makeup mirror is usually a sliding cover type / or a flip cover type, and the mirror cover is manually opened to achieve the lighting and makeup functions; because the driver often passes through bumpy roads during driving, the angle of the sun visor sinks or shakes when the driver has adaptively adjusted the angle of the sun visor, which will bring certain hidden dangers to driving safety. The single flatness structure used in the current sun visor shaft on the car, after the angle is adaptively adjusted, the angle is maintained entirely by the diameter of the shaft and the interference fit of the rigid clamp to ensure the adjustment torque of the sun visor, and the durability of the angle is achieved by adjusting the torque. After the sun visor is repeatedly adjusted 2500 times, the clamping force of the rigid clamp is attenuated, the adjustment torque decreases, and the sun visor sinks, which cannot meet the customer's angle adjustment requirements. In addition, the interference fit has strict requirements on the size of the parts, and there is a risk of abnormal noise, etc. 。 Summary of the invention

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] Please refer to Figure 1-Figure 2 The present application provides a novel sun visor with full-angle adaptive adjustment, including a sun visor body and a rotating shaft 12 mechanism, wherein the sun visor body includes a first shell 10 and a second shell 20, wherein the first shell 10 and the second shell 20 cover and enclose a receiving cavity; the rotating shaft 12 mechanism includes a rotating shaft 12, a rigid clamp 13 and a mounting seat 15, please refer to Figure 3 The rotating shaft 12 includes a first shaft section 121 and a second shaft section 122 connected thereto vertically or approximately vertically. The mounting seat 15 is used to be mounted on the roof interior above the windshield in the car. The first shaft section 121 is rotatably mounted in the mounting seat 15. Please refer to Figure 4-Figure 5 The second shaft segment 122 is rotatably connected to the accommodating cavity through the rigid clamp 13, and at least two flat surfaces are formed on the outer wall of the second shaft segment 122;

[0032] The central axis of the first shaft segment 121 is taken as the Y axis, and the sun visor body is rotated around the Y axis. The sun visor body rotates around the Y axis.

[0033] The central axis of the second shaft segment 122 is taken as the X-axis, and the sun visor body is rotated around it, and the sun visor body rotates around the X-axis as the rotation axis;

[0034] The angle between the axis of the first shaft section 121 and the axis of the second shaft section 122 is 90 degrees. The Y-axis direction is perpendicular to the vehicle body direction, that is, perpendicular to the ground direction by default, and the X-axis is parallel to the ground direction, that is, parallel to the vehicle width direction;

[0035] When the sun visor body is rotated with the X-axis as the rotation axis 12 until the first flat surface 1221 is matched with the rigid clamp 13 in the limit state, the sun visor body is at a non-working angle. Conventionally, the sun visor body is flipped to the minimum sunshade state, that is, the state closest to the car ceiling;

[0036] When the Y-axis is used as the rotating axis 12 and the sun visor body is rotated until the second flat surface 1222 cooperates with the rigid clamp 13 in a limited state, the sun visor body is at a maximum working angle. Conventionally, the sun visor is flipped to a maximum shading state, that is, flipped to the position closest to the front block.

[0037] The present application provides at least two flat surfaces on the rotating shaft 12. The two flat surfaces cooperate with the rigid clamp 13 to limit the sun visor body at a non-working angle or a maximum working angle, thereby replacing the traditional interference fit between the rotating shaft 12 and the rigid clamp 13. The impact on the rigid clamp 13 during rotation is smaller, and the durability of the sun visor is better.

[0038] In one embodiment, the angle between the different radial directions ranges from 45 degrees to 180 degrees, specifically adapted to the personalized sunshade adjustment needs of the driver and passengers; preferably, it is 0 degrees to 180 degrees, with a full-angle flip adjustment function to maximize the sunshade effect.

[0039] In one embodiment, please refer to Figure 6-Figure 8 , the widths of the first flat surface 1221 and the second flat surface 1222 are different; specifically, the first flat surface 1221 corresponds to the non-working angle of the sun visor. Considering the influence of gravity on the sun visor, a larger angle holding force needs to be applied to it. Therefore, the width of the first flat surface 1221 is wider than the width of the second flat surface 1222, that is, the depth of the first flat surface 1221 relative to the circular axis surface of the second rotating shaft 12 is deeper, so as to achieve a stable holding effect on the sun visor in the non-working state; the second flat surface 1222 corresponds to the maximum shading degree of the sun visor, and it only needs to maintain the flipping angle of the sun visor during the operation of the vehicle. The weight of the sun visor has little effect on it. Therefore, the width of the second flat surface 1222 can be set smaller.

[0040] In one embodiment, the center lines of the first flat surface 1221 and the second flat surface 1222 in the length direction are parallel to the central axis of the second shaft segment 122, and are matched and limited with the rigid clamp 13 during rotation to correspond to the limiting matching effect of a single angle.

[0041] In one embodiment, the inner wall surface of the clamp part of the rigid clamp 13 has a flat surface. When the second shaft segment 122 is rotated to the first flat surface 1221 or the second flat surface 1222 to match the rigid clamp 13 in a limited state, the flat surface fits with the first flat surface 1221 or the second flat surface 1222 to limit the sun visor body at a non-working angle and a maximum working angle, respectively, and the limiting effect is more stable.

[0042] In one embodiment, the straight surface and the curved surface of the clamp are connected with each other in a smooth transition to avoid abnormal rotation noise during the rotation of the shaft 12 .

[0043] In one embodiment, the first flat surface 1221 and the second flat surface 1222 are arranged asymmetrically to match different viewing angles of different vehicle types to achieve the maximum adjustment angle limit of the sun visor.

[0044] In the example shown, the first flat surface 1221 and the second flat surface 1222 are located in the middle of the second shaft segment 122 .

[0045] In one embodiment, a clamping portion is provided on the outer wall surface in the middle of the second shaft segment 122. The clamping portion is cylindrical. The diameter of the clamping portion is smaller than the diameter of the second shaft segment 122 and is used to limit the clamping position of the rigid clamp 13 between the second shaft segment 122 to avoid the axial displacement of the rigid clamp 13 on the second shaft segment 122 when the sun visor body is rotated in the horizontal direction, resulting in obstruction of the flip adjustment function of the sun visor. The first flat surface 1221 and the second flat surface 1222 are arranged on the outer wall surface of the clamping portion.

[0046] In the present application, a double flat surface is provided to match and limit the rigid clamp 13, so that the second shaft segment 122 of the rotating shaft 12 does not need to be interference fit with the rigid clamp 13, and the diameter of the shaft segment where the second shaft segment 122 and the rigid clamp 13 match is slightly smaller than the diameter of the rotatable space inside the clamping part of the rigid clamp 13.

[0047] In the present application, the height difference between the first flat surface 1221 and the second flat surface 1222 and the outer cylindrical shaft wall of the second shaft segment 122 is small, so as not to cause the rigid clamp 13 to be greatly deformed or make abnormal noise when the rotating shaft 12 is rotated.

[0048] Typically, a covering fabric 30 is provided on the bottom surface of the second shell 20, a makeup mirror 11 or a makeup light is provided on the first shell 10, and a hook 14 is provided at a corner of the top of the first shell 10 to enhance the interior effect and functionality of the sun visor.

[0049] In a second aspect, the present application provides a vehicle comprising the novel full-angle adaptive sun visor as described above.

[0050] The vehicle provided in the present application has two flat surfaces on the rotating shaft 12. During the adjustment process, the flat surface replaces the interference fit and the arc surface matches the rigid clamp 13, and the rigid clamp 13 is cooperated to adjust the limit, which has less impact on the rigid clamp 13 and better durability of the sun visor.
