Description
Technical Field
[0001] This invention relates to the field of vehicles, and more particularly to a sun visor device and a vehicle. Background Technology
[0002] Vehicle sun visors are used to block strong sunlight and prevent it from affecting the vision of drivers and passengers, thus ensuring safe driving. In related technologies, to improve the sun visor's shading effect, the overall area of the sun visor is increased. However, a large overall area of the sun visor makes it easier for it to collide with the driver during opening and closing, affecting driving safety. Summary of the Invention

[0029] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0030] The following is for reference. Figures 1-3 A sun visor device 100 for a vehicle according to an embodiment of the present invention is described.
[0031] like Figures 1-3 As shown, a sun visor device 100 for a vehicle according to a first aspect embodiment of the present invention includes: a mounting bracket 10, a sun visor 20, and a transmission mechanism 30.
[0032] Mounting bracket 10 is suitable for mounting and fixing to the roof panel of the vehicle body. The sun visor 20 can be mounted on the roof panel of the vehicle body via mounting bracket 10, thus achieving the installation and fixation of the sun visor 20. The sun visor 20 includes a sun visor bracket 2 and a sun visor body 3 disposed on the sun visor bracket 2. The sun visor bracket 2 and mounting bracket 10 are rotatably connected, allowing the sun visor 20 to rotate between a sun-shading position and a retracted position. When the sun visor bracket 2 rotates relative to the mounting bracket 10, it will drive the sun visor body 3 to rotate relative to the mounting bracket 10, achieving the overall sun-shading effect of the sun visor 20 through the sun visor body 3. The rotatable connection between the sun visor bracket 2 and mounting bracket 10 allows users to easily select whether to use the sun visor 20's sun-shading effect according to their needs, and facilitates the opening or retraction of the sun visor 20.
[0033] The sun visor body 3 has a first end 31 and a second end 32 arranged opposite to each other. When the sun visor 20 is in the sun-shading position, the second end 32 is located below the first end 31, allowing the sun visor body 3 to extend vertically. The entire sun visor body 3 is positioned in front of the driver, blocking strong light and achieving the sun-shading effect of the sun visor 20, thus meeting the driver's sun-shading needs. When the sun visor 20 is in the retracted position, the second end 32 is located behind the first end 31, allowing the sun visor body 3 to extend horizontally. This brings the sun visor body 3 closer to the roof of the vehicle, making the overall structure more compact. The sun visor body 3 is movable relative to the sun visor bracket 2 in the arrangement direction of the first end 31 and the second end 32, allowing the distance between the second end 32 of the sun visor body 3 and the sun visor bracket 2 to be adjusted according to user needs. For example, the sun visor body 3 can move relative to the sun visor bracket 2 in the direction from the first end 31 to the second end 32, or the sun visor body 3 can move relative to the sun visor bracket 2 in the direction from the second end 32 to the first end 31.
[0034] The transmission mechanism 30 is tractably connected between the mounting bracket 10 and the sun visor body 3. The transmission mechanism 30 is configured such that when the sun visor bracket 2 rotates relative to the mounting bracket 10, the transmission mechanism 30 drives the sun visor body 3 to move along the arrangement direction of the first end 31 and the second end 32. Therefore, when the sun visor bracket 2 drives the sun visor body 3 to rotate relative to the mounting bracket 10, the distance between the second end 32 of the sun visor body 3 and the sun visor bracket 2 can be adjusted through the transmission mechanism 30, meeting the user's needs for the extension length of the sun visor body 3 relative to the sun visor bracket under different circumstances.
[0035] Specifically, during the process of the sun visor 20 rotating from the retracted position to the sun-shading position, the sun visor body 3 moves along the direction from the first end 31 to the second end 32; during the process of the sun visor 20 rotating from the sun-shading position to the retracted position, the sun visor body 3 moves along the direction from the second end 32 to the first end 31. This arrangement allows the larger sun visor body 3 to maintain a safe distance between the second end 32 of the sun visor 20 and the driver during opening or retraction, thereby reducing the risk of collision between the sun visor 20 and the driver during opening or retraction, improving user driving safety. Simultaneously, the larger overall area of the sun visor 20 enhances the overall sun-shading effect of the sun visor device 100.
[0036] As the sun visor 20 rotates from its retracted position to its shading position, the second end 32 of the sun visor body 3 moves downwards and forwards. Simultaneously, driven by the transmission mechanism 30, the sun visor body 3 moves relative to the sun visor bracket 2 from its first end 31 to its second end 32. This continuously increases the distance between the second end 32 of the sun visor body 3 and the sun visor bracket 2, and the extension length of the sun visor body 3 relative to the sun visor bracket 2 continuously increases. Consequently, the shading area of the sun visor body 3 continuously increases. When the sun visor 20 reaches the shading position, the shading area of the sun visor body 3 is at its maximum, improving the overall shading effect of the sun visor device 100. Furthermore, before the sun visor 20 reaches the shading position, compared to when the sun visor body 3 is directly connected to the mounting bracket 10, the extension length of the sun visor body 3 relative to the sun visor bracket is smaller. This reduces the risk of collision between the sun visor 20 and the driver during the opening process, improving user driving safety.
[0037] As the sun visor 20 rotates from the sunshade position to the retracted position, the second end 32 of the sun visor body 3 moves upward and backward. Simultaneously, driven by the transmission mechanism 30, the sun visor body 3 moves relative to the sun visor bracket 2 from the second end 32 to the first end 31. This continuously reduces the distance between the second end 32 of the sun visor body 3 and the sun visor bracket 2, and shortens the extension length of the sun visor body 3 relative to the sun visor bracket 2. As the sun visor 20 retracts, a safe distance is maintained between the second end 32 of the sun visor body 3 and the driver, reducing the risk of collision between the sun visor 20 and the driver during retraction and improving user driving safety.
[0038] According to an embodiment of the present invention, a transmission mechanism 30 is provided between the mounting bracket 10 and the sun visor body 3 in the vehicle sun visor device 100. When the sun visor bracket 2 rotates relative to the mounting bracket 10, the transmission mechanism 30 drives the sun visor body 3 to move along the arrangement direction of the first end 31 and the second end 32. This allows the larger area of the sun visor body 3 to maintain a safe distance between the second end 32 of the sun visor body 3 and the driver during the opening or closing process. This reduces the risk of collision between the sun visor 20 and the driver during the opening or closing process, and improves the safety of the user's driving. At the same time, the larger overall area of the sun visor body 3 can improve the overall sunshade effect of the sun visor device 100.
[0039] According to some embodiments of the present invention, with reference to Figure 2-Figure 3 The transmission mechanism 30 includes: a first transmission component 4, a second transmission component 5, and a gear transmission mechanism 6.
[0040] The first transmission member 4 is disposed on the mounting bracket 10 and is fixed relative to the mounting bracket 10. The first transmission member 4 includes a first tooth 41, which extends circumferentially along the rotation axis of the sunshade bracket 2. This facilitates the rotation of the sunshade 20 as a whole relative to the mounting bracket 10, allowing the sunshade 20 as a whole to move along the extension direction of the first tooth 41 of the first transmission member 4, thereby enabling the switching of the sunshade 20 between the sunshade position and the storage position.
[0041] The second transmission component 5 is disposed on the sun visor body 3. The second transmission component 5 includes a second tooth 51, which extends along the arrangement direction of the first end 31 and the second end 32. This facilitates the movement of the sun visor body 3 relative to the sun visor bracket 2 in the arrangement direction of the first end 31 and the second end 32, allowing the sun visor body 3 to move along the extension direction of the second tooth 51 of the second transmission component 5. This enables the adjustment of the distance between the second end 32 of the sun visor body 3 and the sun visor bracket 2 according to user needs. For example, the second transmission component 5 can be a rack, which facilitates the extension of the second tooth 51 along the arrangement direction of the first end 31 and the second end 32, resulting in a larger contact area between the second transmission component 5 and the sun visor body 3, ensuring the stability and reliability of the connection between the second transmission component 5 and the sun visor body 3.
[0042] A gear transmission mechanism 6 is mounted on the sun visor bracket 2 and includes at least one transmission gear. For example, the gear transmission mechanism 6 may include one transmission gear or multiple transmission gears. The transmission gear can be mounted on the sun visor bracket 2 via a mounting shaft, and the transmission gear can rotate relative to the mounting shaft, which can fix the transmission gear. The gear transmission mechanism 6 meshes with both the first tooth portion 41 and the second tooth portion 51. During the rotation of the sun visor 20 relative to the mounting bracket 10, the gear transmission mechanism 6 meshes with the first tooth portion 41, enabling the rotation of the sun visor 20 around the mounting bracket 10. The gear transmission mechanism 6 meshes with the second tooth portion 51, enabling the movement of the sun visor body 3 relative to the sun visor bracket 2 in the arrangement direction of the first end 31 and the second end 32. The gear transmission mechanism 6 has advantages such as smooth transmission, high transmission accuracy, long service life, and high transmission efficiency.
[0043] Therefore, the gear transmission mechanism 6 meshes with both the first tooth 41 and the second tooth 51, allowing the sun visor body 3 to move along the arrangement direction of the first end 31 and the second end 32 when the sun visor bracket 2 rotates relative to the mounting bracket 10. This ensures that the second end 32 of the sun visor body 3, which has a larger area, maintains a safe distance from the driver during the opening or closing process, thereby reducing the risk of collision between the sun visor 20 and the driver during the opening or closing process and improving the safety of the user's driving.
[0044] According to some embodiments of the present invention, with reference to Figures 1-3 The mounting bracket 10 has a rotating shaft 11, and the sun visor bracket 2 has a rotating hole. The rotating shaft 11 passes through the rotating hole, allowing the sun visor bracket 2 to rotate around the rotating shaft 11 of the mounting bracket 10, thereby facilitating the switching of the sun visor 20 as a whole between the storage position and the sun visor position. The first transmission member 4 is disposed on the rotating shaft 11 and is fixed relative to the rotating shaft 11. The gear transmission mechanism 6 is located on the side of the first transmission member 4 adjacent to the second end 32, allowing the gear transmission mechanism 6 to be positioned between the first transmission member 4 and the second transmission member 5. This facilitates the meshing of the gear transmission mechanism 6 with the first tooth 41 of the first transmission member 4 and the second tooth 51 of the second transmission member 5, thereby realizing the transmission connection between the gear transmission mechanism 6 and the first transmission member 4 and the second transmission member 5.
[0045] The second transmission component 5 is located on one side of the thickness direction of the sunshade body 3, which can make the overall structure of the sunshade 20 more compact, facilitate the transmission connection between the gear transmission mechanism 6 and the second transmission component 5, and facilitate the movement of the sunshade body 3 along the arrangement direction of the first end 31 and the second end 32, so as to realize the distance adjustment between the second end 32 of the sunshade body 3 and the sunshade bracket 2.
[0046] According to some embodiments of the present invention, with reference to Figure 2-Figure 3 The first transmission component 4 is a gear, which facilitates the fixing of the first transmission component 4 to the rotating shaft 11 of the mounting bracket 10, and also makes the transmission connection between the first transmission component 4 and the gear transmission mechanism 6 more stable. The first tooth 41 is formed on the outer peripheral wall of the first transmission component 4. During the rotation of the sunshade bracket 2 around the rotating shaft 11, the gear transmission mechanism 6 meshes with the first tooth 41, which allows the gear transmission mechanism 6 to rotate relative to the first transmission component 4, thereby driving the second transmission component 5 to move, realizing the movement of the sunshade body 3 along the arrangement direction of the first end 31 and the second end 32.
[0047] According to some embodiments of the present invention, with reference to Figure 2The gear transmission mechanism 6 includes a transmission gear, specifically a first transmission gear 61, which meshes with both a first tooth portion 41 and a second tooth portion 51. The first transmission gear 61 meshes with both the first tooth portion 41 of the first transmission member 4 and the second tooth portion 51 of the second transmission member 5, allowing the sun visor body 3 to move along the arrangement direction of the first end 31 and the second end 32 when the sun visor bracket 2 rotates relative to the mounting bracket 10. The first transmission gear 61 can be mounted on the mounting bracket 10 via a first mounting shaft 611, and can rotate relative to the first mounting shaft 611. For example, the first mounting shaft 611 can be located on the side of the rotating shaft 11 adjacent to the second end 32, with the rotating shaft 11 and the first mounting shaft 611 spaced apart sequentially along the arrangement direction from the first end 31 to the second end 32.
[0048] When the sun visor 20 is in the shading position, the sun visor body 3 is located behind the first transmission gear 61; when the sun visor 20 is in the retracted position, the sun visor body 3 is located above the first transmission gear 61. With this configuration, as the sun visor 20 rotates from the retracted position to the shading position, the sun visor bracket 2 rotates counterclockwise around the pivot 11 of the mounting bracket 10, and simultaneously the first transmission gear 61 rotates counterclockwise around the first transmission member 4. The first transmission gear 61 meshes with the first tooth 41, causing the first transmission gear 61 itself to rotate counterclockwise. When the first transmission gear 61 meshes with the second tooth 51 and is in the sunshade position, the sun visor body 3 is located behind the first transmission gear 61. As the first transmission gear 61 rotates, it drives the sun visor body 3 to move along the direction from the first end 31 to the second end 32. This continuously increases the distance between the second end 32 of the sun visor body 3 and the sun visor bracket 2, thus continuously increasing the sunshade area of the sun visor body 3. When the sun visor 20 reaches the sunshade position, the sunshade area of the sun visor body 3 is at its maximum, improving the overall sunshade effect of the sun visor device 100. Furthermore, before the sun visor 20 reaches the sunshade position, compared to when the sun visor body 3 is directly connected to the mounting bracket 10, the extension length of the sun visor body 3 relative to the sun visor bracket is smaller. This reduces the risk of collision between the sun visor 20 and the driver during the opening process, improving user driving safety.
[0049] As the sun visor 20 rotates from the sunshade position to the retracted position, the sun visor bracket 2 rotates clockwise around the pivot 11 of the mounting bracket 10, and simultaneously the first transmission gear 61 rotates clockwise around the first transmission component 4. The first transmission gear 61 meshes with the first tooth 41, causing the first transmission gear 61 itself to rotate clockwise. When the first transmission gear 61 meshes with the second tooth 51 and the sun visor body 3 is located behind the first transmission gear 61 in the sunshade position, the rotation of the first transmission gear 61 drives the sun visor body 3 to move along the direction from the second end 32 to the first end 31. This continuously reduces the distance between the second end 32 of the sun visor body 3 and the sun visor bracket 2, maintaining a safe distance between the second end 32 of the sun visor body 3 and the driver during the retraction process, reducing the risk of collision between the sun visor 20 and the driver, and improving user driving safety.
[0050] According to some embodiments of the present invention, with reference to Figure 3 The gear transmission mechanism 6 includes two meshing transmission gears, namely a second transmission gear 62 and a third transmission gear 63. The first transmission member 4, the second transmission gear 62, and the third transmission gear 63 are arranged sequentially along the direction from the first end 31 to the second end 32. The second transmission gear 62 meshes with the first tooth portion 41, and the third transmission gear 63 meshes with the second tooth portion 51. The second transmission gear 62 meshes with both the first tooth portion 41 of the first transmission member 4 and the third transmission gear 63. The third transmission gear 63 meshes with both the second tooth portion 51 of the second transmission member 5 and the second transmission gear 62. When the sun visor bracket 2 rotates relative to the mounting bracket 10, the sun visor body 3 can move along the arrangement direction of the first end 31 and the second end 32.
[0051] The second transmission gear 62 can be mounted on the mounting bracket 10 via the second mounting shaft 621, and the second transmission gear 62 can rotate relative to the second mounting shaft 621. The third transmission gear 63 can be mounted on the mounting bracket 10 via the third mounting shaft 631, and the third transmission gear 63 can rotate relative to the third mounting shaft 631. For example, the second mounting shaft 621 can be located on the side of the rotating shaft 11 adjacent to the second end 32, and the third mounting shaft 631 can be located on the side of the second mounting shaft 621 adjacent to the second end 32. The rotating shaft 11, the second mounting shaft 621, and the third mounting shaft 631 are arranged at intervals along the arrangement direction from the first end 31 to the second end 32.
[0052] When the sun visor 20 is in the shading position, the sun visor body 3 is located in front of the gear transmission mechanism 6; when the sun visor 20 is in the retracted position, the sun visor body 3 is located below the gear transmission mechanism 6. With this configuration, as the sun visor 20 rotates from the retracted position to the shading position, the sun visor bracket 2 rotates counterclockwise around the pivot 11 of the mounting bracket 10, and simultaneously the second transmission gear 62 rotates counterclockwise around the first transmission member 4. The second transmission gear 62 meshes with the first tooth 41, causing the second transmission gear 62 itself to rotate counterclockwise. The second transmission gear 62 meshes with the third transmission gear 63, causing the third transmission gear 63 to rotate in the opposite direction to the second transmission gear 62, resulting in the second transmission gear 62 rotating clockwise.
[0053] When the third transmission gear 63 meshes with the second tooth 51 and is in the sunshade position, the sun visor body 3 is located in front of the first transmission gear 61. As the third transmission gear 63 rotates, it drives the sun visor body 3 to move along the direction from the first end 31 to the second end 32. This continuously increases the distance between the second end 32 of the sun visor body 3 and the sun visor bracket 2, thus continuously increasing the sunshade area of the sun visor body 3. When the sun visor 20 reaches the sunshade position, the sunshade area of the sun visor body 3 is at its maximum, improving the overall sunshade effect of the sun visor device 100. Furthermore, before the sun visor 20 reaches the sunshade position, compared to when the sun visor body 3 is directly connected to the mounting bracket 10, the extension length of the sun visor body 3 relative to the sun visor bracket is smaller. This reduces the risk of collision between the sun visor 20 and the driver during the opening process, improving user driving safety.
[0054] As the sun visor 20 rotates from its shading position to its retracted position, the sun visor bracket 2 rotates clockwise around the pivot 11 of the mounting bracket 10, while the second transmission gear 62 rotates clockwise around the first transmission member 4. The second transmission gear 62 meshes with the first tooth 41, causing it to rotate clockwise. The second transmission gear 62 also meshes with the third transmission gear 63, causing the third transmission gear 63 to rotate in the opposite direction to the second transmission gear 62, resulting in the second transmission gear 62 rotating counter-clockwise. When the third transmission gear 63 meshes with the second tooth 51 and the sun visor body 3 is in the sunshade position, it is located in front of the first transmission gear 61. As the third transmission gear 63 rotates, it drives the sun visor body 3 to move along the direction from the second end 32 to the first end 31. This allows the distance between the second end 32 of the sun visor body 3 and the sun visor bracket 2 to continuously decrease. During the retraction of the sun visor 20, a safe distance is maintained between the second end 32 of the sun visor body 3 and the driver, reducing the risk of collision between the sun visor 20 and the driver during the retraction process and improving the safety of the user's driving.
[0055] According to some embodiments of the present invention, with reference to Figure 3 The outer diameter of the third transmission gear 63 is larger than that of the second transmission gear 62. This arrangement ensures that a safe distance is maintained between the sun visor body 3 and the outer peripheral wall of the second transmission gear 62 during the movement of the sun visor body 3 along the arrangement direction of the first end 31 and the second end 32. This prevents interference between the sun visor body 3 and the second transmission gear 62, thus ensuring the normal movement of the sun visor body 3 and the normal use of the sun visor 20 as a whole.
[0056] According to some embodiments of the present invention, with reference to Figure 2-Figure 3 The second transmission component 5 is located at the first end 31, which can shorten the distance between the second transmission component 5, the first transmission component 4, and the gear transmission mechanism 6, making it easier to connect the second transmission component 5 and the gear transmission mechanism 6. At the same time, it can make the overall structure of the transmission mechanism 30 more compact, and make the sunshade device 100 occupy less space.
[0057] According to some embodiments of the present invention, with reference to Figures 1-3 The sun visor bracket 2 has a sliding cavity 21, and a rotating hole is formed on the side wall of the sliding cavity 21. The rotating shaft 11 of the mounting bracket 10 passes through the rotating hole on the side wall of the sliding cavity 21, allowing the sun visor bracket 2 to rotate around the rotating shaft 11 of the mounting bracket 10 through the rotating hole, thereby facilitating the switching of the sun visor 20 as a whole between the storage position and the sun visor position. The first transmission component 4 and the gear transmission mechanism 6 are both located in the sliding cavity 21, and the first end 31 of the sun visor body 3 is located in the sliding cavity 21, which can shorten the distance between the first transmission component 4, the second transmission component 5, and the gear transmission mechanism 6, facilitating the transmission connection between the first transmission component 4, the second transmission component 5, and the gear transmission mechanism 6. At the same time, the first transmission component 4, the second transmission component 5, and the gear transmission mechanism 6 are all located in the sliding cavity 21, so that the sliding cavity 21 has a accommodating and protective function for the transmission mechanism 30 as a whole, ensuring the normal use of the transmission mechanism 30.
[0058] The sun visor body 3 is slidable relative to the sliding cavity 21 to adjust the length of the sun visor 20 in the arrangement direction of the first end 31 and the second end 32. The sliding cavity 21 can guide the sun visor body 3, ensuring that the sun visor body 3 can move along the arrangement direction of the first end 31 and the second end 32. Thus, when the sun visor body 3 rotates relative to the mounting bracket 10, the distance between the second end 32 of the sun visor body 3 and the sun visor bracket 2 can be adjusted, meeting the user's needs for the extension length of the sun visor body 3 relative to the sun visor bracket under different conditions.
[0059] According to some embodiments of the present invention, with reference to Figure 3The mounting bracket 10 has two rotating shafts 11 spaced apart in the left-right direction. Each rotating shaft 11 is equipped with a first transmission component 4, and two second transmission components 5 are spaced apart in the left-right direction. Each first transmission component 4 and its corresponding second transmission component 5 are connected by a gear transmission mechanism 6. The left and right sides of the sun visor body 3 are connected to the mounting bracket 10 through the transmission mechanism 30, which makes the force on the sun visor 20 more even and improves the stability and reliability of the connection between the sun visor 20 and the mounting bracket 10. At the same time, it can improve the stability of the sun visor 20 during movement, ensuring that the sun visor 20 moves along the set movement trajectory and maintains a safe distance between the second end 32 of the sun visor body 3 and the driver. This reduces the risk of collision between the sun visor 20 and the driver during opening or closing, and improves the safety of the user's driving.
[0060] According to some optional embodiments of the present invention, the sun visor body 3 is a light-transmitting plate, and the light transmittance of the sun visor body 3 is adjustable. The sun visor body 3 can employ a set of control circuits with photosensitive elements and current and voltage regulation functions to detect the ambient light intensity, and automatically and steplessly adjust the light transmittance according to the detected ambient light intensity. Alternatively, the light shading rate can be set to several manual levels, allowing manual adjustment of the light transmittance according to the ambient light intensity. Thus, the light transmittance of the sun visor body 3 can be adjusted according to the ambient light intensity, so that the human eye is under a relatively comfortable light intensity under the action of the sun visor body 3, while maintaining a good field of vision. This allows occupants of the vehicle to be protected from the stimulation of strong light from outside the vehicle, while still being able to clearly observe the outside situation, thus significantly improving the comfort and safety of the occupants.
[0061] For example, in some other embodiments of the present invention, the light transmittance of the sun visor body 3 can be fixed. The sun visor body 3 can be made of a dark-colored organic or inorganic material with a fixed light transmittance, so that the occupants of the vehicle can be protected from the stimulation of strong light from outside the vehicle, while still being able to observe the outside situation relatively clearly, thus improving the comfort and safety of the occupants.
[0062] A vehicle according to a second aspect embodiment of the present invention includes: a sun visor device 100 of the vehicle according to the first aspect embodiment of the present invention described above.
[0063] According to the vehicle of the present invention, by setting the sun visor device 100 described above, a transmission mechanism 30 is provided between the mounting bracket 10 and the sun visor body 3. When the sun visor bracket 2 rotates relative to the mounting bracket 10, the transmission mechanism 30 drives the sun visor body 3 to move along the arrangement direction of the first end 31 and the second end 32. This allows the larger area of the sun visor body 3 to maintain a safe distance between the second end 32 of the sun visor body 3 and the driver during the opening or closing process. This reduces the risk of collision between the sun visor 20 and the driver during the opening or closing process, and improves the safety of the user's driving. At the same time, the larger overall area of the sun visor body 3 can improve the overall sunshade effect of the sun visor device 100.
