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 sun-shading effect, the overall area of the sun visor is increased. However, with a larger overall area, the free end of the sun visor can easily collide with the driver during opening and closing, affecting driving safety. Summary of the Invention
[0003] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of this invention is to provide a sun visor device for a vehicle, wherein one end of a linkage assembly is rotatably connected to a mounting bracket, and the other end of the linkage assembly is rotatably connected to the connecting end of the sun visor.

[0006] According to an embodiment of the present invention, in a vehicle sun visor device, one end of a linkage assembly is rotatably connected to a mounting bracket, and the other end of the linkage assembly is rotatably connected to the connecting end of the sun visor. This allows the free end of the sun visor to maintain a safe distance from the driver during the opening or closing of the large-area sun visor, thereby reducing the risk of collision between the sun visor and the driver during opening or closing and improving the safety of the user's driving. At the same time, the large overall area of the sun visor can improve the overall sunshade effect of the sun visor device.
[0007] According to some embodiments of the present invention, the linkage assembly includes a first linkage, one end of which is rotatably connected to the mounting bracket, and the other end of which is rotatably connected to the connecting end.

[0009] According to some embodiments of the present invention, the elastic support rod includes: a first support rod, a spring, and a second support rod. One end of the first support rod is rotatably connected to the mounting bracket. A sliding cavity is formed inside the first support rod. The sliding cavity extends along the length direction of the first support rod and passes through the end face of the other end of the first support rod. The second support rod is slidably inserted into the sliding cavity along the length direction of the elastic support rod. The spring is disposed in the sliding cavity and connects the first support rod and the second support rod.
[0010] According to some embodiments of the present invention, when the sunshade is in the sunshade position, the elastic strut has a forward elastic force on the sunshade.
[0011] According to some embodiments of the present invention, when the sun visor is in the retracted position, the elastic strut has an elastic force toward the top plate on the sun visor to hold the sun visor in the retracted position.
[0012] According to some embodiments of the present invention, the linkage assembly further includes a second linkage, one end of which is rotatably connected to the mounting bracket, and the other end of which is rotatably connected to the connecting end. When the sunshade is in the sunshade position, the second linkage extends obliquely in the vertical direction.
[0013] According to some embodiments of the present invention, the mounting bracket, the first link, the connecting end, and the second link constitute a four-bar linkage.
[0014] According to some embodiments of the present invention, the length of the second connecting rod is greater than the length of the first connecting rod, the connection point between the first connecting rod and the mounting bracket is a first connection point, the connection point between the first connecting rod and the connecting end is a second connection point, the connection point between the second connecting rod and the mounting bracket is a third connection point, and the connection point between the second connecting rod and the connecting end is a fourth connection point; wherein, the third connection point is located behind the first connection point, and the fourth connection point is located below the second connection point.
[0015] According to some embodiments of the present invention, the linkage assembly further includes: an elastic strut, one end of which is rotatably connected to the mounting bracket, and the other end of which is rotatably connected to the connecting end. During the process of the sun visor moving from the storage position to the sunshade position, the elastic strut has an elastic force for driving the sun visor toward the sunshade position. The connection point between the elastic strut and the mounting bracket is a fifth connection point, which is located between the first connection point and the third connection point in the front-back direction. The connection point between the elastic strut and the connecting end is a sixth connection point, which is concentrically arranged with the fourth connection point.
[0016] According to some optional embodiments of the present invention, there are two connecting rod assemblies arranged on the left and right sides.

[0031] 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.
[0032] The following is for reference. Figures 1-4 A sun visor device 100 for a vehicle according to an embodiment of the present invention is described.
[0033] like Figure 1 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 linkage assembly 30.
[0034] Mounting bracket 10 is suitable for mounting and fixing to the roof panel of the vehicle body. The sun visor 20 is movable between a sun-shading position and a retracted position, allowing users to easily select whether to use the sun-shading effect of the sun visor 20 according to their needs, and facilitating the opening or retraction of the sun visor 20. The sun visor 20 has a connecting end 21 and a free end 22 arranged opposite to each other. The connecting end 21 is used for mounting and fixing the sun visor 20, and the body of the sun visor 20 can move relative to the connecting end 21, so that the sun visor 20 is in either a sun-shading position or a retracted position.
[0035] When the sun visor 20 is in the sunshade position, the free end 22 is located below the connecting end 21, allowing the sun visor 20 to extend vertically and achieve a sunshade effect, meeting the driver's sunshade needs. When the sun visor 20 is in the retracted position, the free end 22 is located behind the connecting end 21, allowing the sun visor 20 to be closer to the roof of the vehicle body, making the overall structure more compact.
[0036] One end of the linkage assembly 30 is rotatably connected to the mounting bracket 10, and the other end of the linkage assembly 30 is rotatably connected to the connecting end 21. The sun visor 20 is connected to the mounting bracket 10 via the linkage assembly, allowing the sun visor 20 to be mounted on the roof of the vehicle body. The linkage assembly 30, the mounting bracket 10, and the sun visor 20 are all rotatably connected, facilitating the movement of the sun visor 20 between the shading position and the retracted position, and making it easy to open or retract the sun visor 20. During the opening or retraction process, the connecting end 21 of the sun visor 20 rotates around one end of the linkage assembly 30, while the other end of the linkage assembly 30 rotates around the mounting bracket 10, thereby enabling the switching between the shading position and the retracted position of the sun visor 20.
[0037] When the sun visor 20 is in the shading position, the end of the linkage assembly 30 connected to the connecting end 21 is located below the end of the linkage assembly connected to the mounting bracket 10. When the sun visor 20 is in the retracted position, the end of the linkage assembly 30 connected to the connecting end 21 is located in front of the end of the linkage assembly connected to the mounting bracket 10, so that the linkage assembly 30 and part of the sun visor 20 are located on the front side of the mounting bracket 10.
[0038] As the sun visor 20 moves from the sunshade position to the retracted position, the free end 22 of the sun visor 20 rotates upward and backward while the linkage assembly 30 rotates upward and forward. The linkage assembly 30 drives the connecting end 21 of the sun visor 20 to move towards the front of the mounting bracket 10, gradually increasing the portion of the sun visor 20 in front of the mounting bracket 10. This allows the entire sun visor 20 to move towards the front of the mounting bracket 10 during the retraction process, thereby maintaining a safe distance between the free end 22 of the sun visor 20 and the driver, reducing the risk of collision between the sun visor 20 and the driver during the retraction process, and improving the user's driving safety.
[0039] As the sun visor 20 moves from its retracted position to its awning position, the free end 22 of the sun visor 20 rotates downwards and forwards while the connecting rod assembly 30 rotates downwards and backwards. The connecting rod assembly 30 drives the connecting end 21 of the sun visor 20 to move downwards towards the mounting bracket 10, causing the entire sun visor 20 to move downwards towards the mounting bracket 10 during the opening process. Because the sun visor 20 is partially located at the front of the mounting bracket 10 in the retracted position, compared to when the sun visor 20 is directly connected to the mounting bracket 10, the portion of the sun visor 20 located at the rear of the mounting bracket 10 is smaller. This reduces the risk of a collision between the sun visor 20 and the driver during the opening process, improving driving safety.
[0040] According to an embodiment of the present invention, in the vehicle sun visor device 100, one end of the connecting rod assembly 30 is rotatably connected to the mounting bracket 10, and the other end of the connecting rod assembly 30 is rotatably connected to the connecting end 21 of the sun visor 20. This allows the free end 22 of the sun visor 20 to maintain 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. At the same time, the large overall area of the sun visor 20 can improve the overall sunshade effect of the sun visor device 100.
[0041] According to some embodiments of the present invention, with reference to Figures 1-3The linkage assembly 30 includes a first linkage 3. One end of the first linkage 3 is rotatably connected to the mounting bracket 10, and the other end is rotatably connected to the connecting end 21. The first linkage 3 is rotatably connected to both the mounting bracket 10 and the sun visor 20, facilitating the movement of the sun visor 20 between the sun-shading position and the retracted position, and making it easy to open or retract the sun visor 20. When the sun visor 20 is in the sun-shading position, the first linkage 3 extends vertically. This vertical extension maximizes the vertical distance between the two ends of the first linkage 3, meaning the vertical distance between the two ends of the first linkage 3 is equal to the length of the first linkage 3. This ensures that the sun visor 20 is in its lowest position, guaranteeing its sun-shading effect and meeting the driver's sun-shading needs.
[0042] According to some embodiments of the present invention, with reference to Figures 1-4 The linkage assembly 30 also includes an elastic strut 5. One end of the elastic strut 5 is rotatably connected to the mounting bracket 10, and the other end is rotatably connected to the connecting end 21. The elastic strut 5 is rotatably connected to both the mounting bracket 10 and the sun visor 20, facilitating the movement of the sun visor 20 between the sun-shading position and the retracted position, and facilitating the opening or retraction of the sun visor 20. During the movement of the sun visor 20 from the retracted position to the sun-shading position, the elastic strut 5 provides an elastic force to drive the sun visor 20 toward the sun-shading position. This allows the sun visor device 100 to achieve the assisted opening function of the sun visor 20 through the elastic strut 5, avoiding continuous manual operation by the driver and thus improving driving safety.
[0043] For example, the elastic force of the elastic strut 5 can continuously increase the overall length of the elastic strut 5. When the sunshade 20 is in the sunshade position, the length of the elastic strut 5 is at its maximum length. Under the action of the elastic force, the elastic strut 5 cannot continue to increase its length, so that the sunshade 20 will stop moving after reaching the sunshade position.
[0044] According to some embodiments of the present invention, with reference to Figure 2 and Figure 4The elastic support rod 5 includes a first support rod 51, a spring 52, and a second support rod 53. One end of the first support rod 51 is rotatably connected to the mounting bracket 10. A sliding cavity 511 is formed inside the first support rod 51, extending along the length of the first support rod 51 and penetrating the end face of the other end of the first support rod 51. The second support rod 53 is slidably inserted into the sliding cavity 511 along the length of the elastic support rod 5. One end of the second support rod 53 is accommodated in the sliding cavity 511 of the first support rod 51, and the other end is rotatably connected to the connecting end 21 of the sunshade 20. The sliding cavity 511 of the first support rod 51 can guide and limit the movement of the second support rod 53, allowing the second support rod 53 to move along the extension direction of the sliding cavity 511.
[0045] A spring 52 is located within the sliding cavity 511 and connects the first support rod 51 and the second support rod 53. The spring 52 can drive the second support rod 53 to slide within the sliding cavity 511, thereby achieving the overall extension and retraction of the elastic support rod 5. One end of the spring 52 elastically abuts against the end face of the second support rod 53 housed within the sliding cavity 511, while the other end elastically abuts against the inner peripheral wall of the sliding cavity 511. One end of the second support rod 53 is connected to the connecting end 21 of the sun visor 20. Under the action of the spring 52's elastic force, the spring 52 can push the second support rod 53 to slide along the sliding cavity 511. The second support rod 53 drives the sun visor 20 to move, thus achieving the overall extension and retraction of the elastic support rod 5, facilitating the opening of the sun visor 20. The structure is simple and the operation is convenient.
[0046] The elastic strut 5 is connected to the mounting bracket 10 via the first strut 51 and to the connecting end 21 of the sunshade 20 via the second strut 53. Under the condition that the size of the spring 52 and the elastic force are constant, the overall elongation of the elastic strut 5 can be larger, so that the elastic strut 5 can be better used for the auxiliary opening and fixing of the large-area sunshade 20.
[0047] According to some embodiments of the present invention, with reference to Figure 2 When the sun visor 20 is in the sunshade position, the elastic strut 5 exerts a forward elastic force on the sun visor 20. When the sun visor 20 is in the sunshade position, it is positioned entirely in front of the driver. When the vehicle travels on uneven roads, the sun visor 20 may sway. If the sun visor 20 sways backward, it could collide with the driver's head, affecting driving safety. Therefore, when the sun visor 20 is in the sunshade position, the forward elastic force exerted by the elastic strut 5 on the sun visor 20 ensures the stability of the sun visor 20 in the sunshade position, reducing the risk of the sun visor 20 swaying backward and colliding with the driver, thereby improving driving safety.
[0048] For example, the elastic force of the elastic strut 5 allows its overall length to continuously increase. When the sun visor 20 is in the sun-shading position, the length of the elastic strut 5 is at its maximum, and it cannot continue to increase in length under the action of the elastic force. Therefore, when the sun visor 20 is in the sun-shading position, the forward elastic force exerted by the elastic strut 5 on the sun visor 20 prevents it from moving forward. The sun visor 20 also cannot move backward under the forward elastic force, thus fixing it in the sun-shading position, reducing the risk of a collision between the sun visor 20 and the driver, and thereby improving driving safety.
[0049] According to some embodiments of the present invention, when the sun visor 20 is in the retracted position, the elastic strut 5 exerts an elastic force on the sun visor 20 toward the roof panel to hold the sun visor 20 in the retracted position. When the sun visor 20 is in the retracted position, the elastic force of the elastic strut 5 on the sun visor 20 toward the roof panel allows the free end 22 of the sun visor 20 to be tightly pressed against the roof panel of the vehicle body, fixing the sun visor 20 relative to the roof panel and holding it in the retracted position. This prevents the sun visor 20 from accidentally opening during vehicle operation and obstructing the driver's view, thereby ensuring the stability of the sun visor 20 in the retracted position and improving the user's driving safety.
[0050] For example, when the sun visor 20 is in the retracted position, it extends at an angle in the vertical direction. When the sun visor 20 moves to the horizontal position, the elastic force of the elastic strut 5 extends horizontally, and continues to rotate the free end 22 of the sun visor 20 upward in the horizontal position, causing the sun visor 20 to extend at an angle in the vertical direction. At the same time, the elastic force of the elastic strut 5 also tilts upward in the vertical direction, so that the free end 22 of the sun visor 20 is pressed tightly against the roof of the vehicle body, fixing the sun visor 20 relative to the roof and keeping it in the retracted position.
[0051] According to some embodiments of the present invention, with reference to Figures 1-2 The linkage assembly 30 also includes a second linkage 4. One end of the second linkage 4 is rotatably connected to the mounting bracket 10, and the other end is rotatably connected to the connecting end 21. The second linkage 4 is rotatably connected to both the mounting bracket 10 and the sun visor 20, facilitating the movement of the sun visor 20 between the sun-shading position and the retracted position, and making it easy to open or retract the sun visor 20. When the sun visor 20 is in the sun-shading position, the second linkage 4 extends obliquely in the vertical direction. This configuration, where the sun visor 20 and the first linkage 3 both extend vertically, and the second linkage 4 extends obliquely in the vertical direction, forms a triangular shape with the first linkage 3, connecting end 21, mounting bracket 10, and second linkage 4. This ensures the stability of the sun visor 20 in the sun-shading position and improves the safety of the driver.
[0052] According to some embodiments of the present invention, with reference to Figure 2 The mounting bracket 10, the first link 3, the connecting end 21, and the second link 4 constitute a four-bar linkage. Four-bar linkages offer advantages such as ease of manufacturing, high manufacturing precision, and the ability to achieve various motion laws and trajectory requirements. The four-bar linkage, consisting of the mounting bracket 10, the first link 3, the connecting end 21, and the second link 4, ensures a safe distance between the free end 22 of the sun visor 20 and the driver during opening or closing. This reduces the risk of collision between the sun visor 20 and the driver, improving driving safety. Furthermore, the large overall area of the sun visor 20 enhances the overall sun-shading effect of the sun visor device 100.
[0053] Furthermore, the sun visor device 100 uses a four-bar linkage to open or retract the sun visor 20, which makes the movement of the sun visor 20 more stable.
[0054] According to some embodiments of the present invention, with reference to Figure 2 The length of the second link 4 is greater than the length of the first link 3. The connection point between the first link 3 and the mounting bracket 10 is the first connection point 31, the connection point between the first link 3 and the connecting end 21 is the second connection point 32, the connection point between the second link 4 and the mounting bracket 10 is the third connection point 41, and the connection point between the second link 4 and the connecting end 21 is the fourth connection point 42. The third connection point 41 is located behind the first connection point 31, and the fourth connection point 42 is located below the second connection point 32. The sun visor 20 can be connected to the link assembly 30 through the second connection point 32 and the fourth connection point 42, which can improve the stability and reliability of the connection between the link assembly 30 and the sun visor 20, thereby ensuring the movement stability of the sun visor 20 under the action of the link assembly 30.
[0055] When the sun visor 20 is in the sunshade position, both the second connection point 32 and the fourth connection point 42 are located below the first connection point 31 and the third connection point 41. When the sun visor 20 is in the retracted position, both the second connection point 32 and the fourth connection point 42 are located in front of the first connection point 31 and the third connection point 41, so that the first connecting rod 3, the second connecting rod 4, and a portion of the sun visor 20 are all located on the front side of the mounting bracket 10.
[0056] As the sun visor 20 moves from its shading position to its retracted position, the free end 22 of the sun visor 20 rotates upwards and backwards while the first link 3 rotates upwards and forwards around the first connection point 31, and the second link 4 rotates upwards and forwards around the third connection point 41. This causes the first link 3, the second link 4, and a portion of the sun visor 20 to continuously move towards the front of the mounting bracket 10. This gradually increases the portion of the sun visor 20 located in front of the mounting bracket 10, allowing the entire sun visor 20 to move towards the front of the mounting bracket 10 during the retraction process. This maintains a safe distance between the free end 22 of the sun visor 20 and the driver, reducing the risk of a collision between the sun visor 20 and the driver during retraction and improving driving safety.
[0057] As the sun visor 20 moves from its retracted position to its sun-shading position, the free end 22 of the sun visor 20 rotates downwards and forwards while the first connecting rod 3 rotates downwards and backwards around the first connection point 31, and the second connecting rod 4 rotates downwards and backwards around the third connection point 41. This causes the sun visor 20 as a whole to move downwards and backwards towards the mounting bracket 10 during the opening process. Because the sun visor 20 is partially located on the front side of the mounting bracket 10 in the retracted position, compared to when the sun visor 20 is directly connected to the mounting bracket 10, the portion of the sun visor 20 located on the rear side of the mounting bracket 10 is smaller. This reduces the risk of a collision between the sun visor 20 and the driver during the opening process, improving user driving safety.
[0058] For example, in some embodiments of the present invention, the length of the second link 4 is greater than the length of the first link 3, the distance between the second connection point 32 and the fourth connection point 42 is less than the length of the first link 3, and the distance between the first connection point 31 and the third connection point 41 is equal to the length of the first link 3. This arrangement ensures the normal switching of the sun visor 20 between the sunshade position and the retracted position, avoids interference between the movement trajectories of the first link 3 and the second link 4, better maintains the safe distance between the free end 22 of the sun visor 20 and the driver during the opening or retraction process, reduces the risk of collision between the sun visor 20 and the driver during the retraction process, and improves the safety of the user's driving.
[0059] According to some embodiments of the present invention, with reference to Figure 2The linkage assembly 30 also includes an elastic strut 5. One end of the elastic strut 5 is rotatably connected to the mounting bracket 10, and the other end is rotatably connected to the connecting end 21. The elastic strut 5 is rotatably connected to both the mounting bracket 10 and the sun visor 20, facilitating the movement of the sun visor 20 between the sun-shading position and the retracted position, and enabling the opening or retraction of the sun visor 20. During the movement of the sun visor 20 from the retracted position to the sun-shading position, the elastic strut 5 provides an elastic force to drive the sun visor 20 toward the sun-shading position. During this movement, the elastic strut 5 provides a continuous elastic force to drive the sun visor 20 toward the sun-shading position. The sun visor 20 stops moving after reaching the sun-shading position. Thus, the sun visor device 100 can achieve the assisted opening function of the sun visor 20 through the elastic strut 5, avoiding continuous manual operation by the driver and improving driving safety.
[0060] The connection point between the elastic strut 5 and the mounting bracket 10 is the fifth connection point 54. In the front-to-back direction, the fifth connection point 54 is located between the first connection point 31 and the third connection point 41. The connection point between the elastic strut 5 and the connecting end 21 is the sixth connection point 55. The sixth connection point 55 is concentrically arranged with the fourth connection point 42. For example, the direction of the elastic force of the elastic strut 5 is always along the length of the elastic strut 5 towards the sixth connection point 55. During the movement of the sunshade 20, the length of the elastic strut 5 will continuously change.
[0061] When the sun visor 20 is in the retracted position, the free end 22 is higher than when the sun visor 20 is in the horizontal position. The concentric arrangement of the sixth connection point 55 and the fourth connection point 42 can minimize the length of the elastic strut 5 when the sun visor 20 is in the horizontal position. When the sun visor 20 is in the sunshade position, the elastic force of the elastic strut 5 on the sun visor 20 is directed towards the roof. This allows the free end 22 of the sun visor 20 to be tightly attached to the roof of the vehicle body, thus fixing the sun visor 20 relative to the roof and keeping it in the retracted position.
[0062] Furthermore, the concentric arrangement of the sixth connection point 55 and the fourth connection point 42 ensures that the elastic strut 5 is at its longest length when the sun visor 20 is in the sun-shading position. This allows the sun visor 20 to be fixed in the sun-shading position under the elastic force of the strut 5, guaranteeing its stability. When the sun visor 20 is in the sun-shading position, the elastic strut 5 exerts a forward elastic force on the sun visor 20, preventing it from swaying backward and colliding with the driver, thus improving driving safety. Simultaneously, under the action of the second link 4, the forward elastic force of the strut 5 on the sun visor 20 prevents it from moving forward, thus avoiding forward swaying that could affect the sun-shading effect of the sun visor device 100 and improving the stability of the sun visor 20 in the sun-shading position.
[0063] According to some optional embodiments of the present invention, refer to Figure 1 The mounting bracket 10 comprises two connecting rod assemblies 30 arranged on the left and right sides. The bracket body 11 extends in the left-right direction and is adapted to connect to the top plate. Two mounting ears 12 are respectively connected to the left and right ends of the bracket body 11. One connecting rod assembly 30 connects the left mounting ear 12 to the connecting end 21, and the other connecting rod assembly 30 connects the right mounting ear 12 to the connecting end 21. The left and right sides of the connecting end 21 of the sun visor 20 are connected to the two mounting ears 12 of the mounting bracket 10 via two connecting rod assemblies 30, which allows for more even force distribution on the sun visor 20, improving the stability and reliability of the connection between the sun visor 20 and the mounting bracket 10. Simultaneously, it improves the stability of the sun visor 20 during movement, ensuring that the sun visor 20 moves along a set trajectory and maintaining a safe distance between the free end 22 of the sun visor 20 and the driver. This reduces the risk of collision between the sun visor 20 and the driver during opening or closing, improving user driving safety.
[0064] For example, the first link 3 in the linkage assembly 30 is connected to the side of the mounting ear 12 away from the connecting end 21 in the left-right direction, and the second link 4 and the elastic support 5 in the linkage assembly 30 are connected to the side of the mounting ear 12 close to the connecting end 21 in the left-right direction. This can prevent interference between the various parts of the linkage assembly 30 during the movement of the sun visor 20, thereby ensuring that the sun visor 20 can open or close normally and ensuring the normal use of the sun visor 20.
[0065] 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.
[0066] According to the vehicle of the present invention, by setting the sun visor device 100 described above, one end of the connecting rod assembly 30 is rotatably connected to the mounting bracket 10, and the other end of the connecting rod assembly 30 is rotatably connected to the connecting end 21 of the sun visor 20. This allows the free end 22 of the sun visor 20 to maintain 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. At the same time, the large overall area of the sun visor 20 can improve the overall sunshade effect of the sun visor device 100.
