[0045] The present invention provides a method for selecting the arrangement position of the hinge axis of a sun visor, aiming to solve the problem that repeated adjustments are required during the arrangement process of the existing vehicle sun visor to check the arrangement result, thus resulting in low design efficiency.

[0046] See also Figure 1 In one embodiment of the present invention, the sun visor hinge axis 9 is extended along the first direction, and the sun visor 8 is rotatably arranged along the sun visor hinge axis 9. The method for selecting the arrangement position of the sun visor hinge axis includes:

[0047] S100, according to the human-machine field of view requirement, obtaining human-machine head arrangement data, wherein the human-machine head arrangement data includes human-machine upper eye point 1, human-machine lower eye point 2 and head envelope surface 3;

[0048] It can be understood that the human-machine vision requirement is the requirement for the driver's spatial vision when the driver sits on the seat of the car 100.

[0049] It should be noted that when the driver sits on the seat of the automobile 100, since the seat of the automobile 100 can at least partially move in the second direction and the third direction, the driver's eyes will also move synchronously during the movement of the seat of the automobile 100 along the second direction and the third direction. Specifically, in the present embodiment, the driver moves together with the seat of the automobile 100, and during the movement, there is an upper human-machine eye point 1 that makes the driver's eyes highest in the third direction, and a lower human-machine eye point 2 that makes the driver's glasses lowest in the third direction.

[0050] It should be further explained that when the driver is sitting on the car seat 100, due to the movement of the car seat 100, the driver's head position will also move along with the movement of the car seat 100. Therefore, during the movement of the driver's head, the surface where his head contour lines converge is the head envelope surface 3.

[0051] S200, establishing a human-machine upper eye sight line 4 extending along the second direction according to the human-machine upper eye point 1, establishing a human-machine lower eye sight line 5 extending along the second direction according to the human-machine lower eye point 2, and establishing a boundary curve 6 extending in the third direction according to the head envelope surface 3;

[0052] It can be understood that the human-machine upper eye sight line 4 is established based on the human-machine upper eye point 1 to ensure that when the driver's eyes are at the human-machine upper eye point 1, the sun visor 8 can accurately block the sunlight that shines on the driver's eyes; similarly, the human-machine lower eye sight line 5 is established based on the human-machine lower eye point 2 to ensure that when the driver's glasses are at the human-machine lower eye point 2, the sun visor 8 can accurately block the sunlight that shines on the driver's eyes.

[0053] In addition, the boundary curve 6 is provided to ensure that when the driver uses the sun visor 8, the sun visor 8 does not produce a sense of oppression on the driver, thereby ensuring a normal use experience for the driver.

[0054] It should also be noted that, in this embodiment, the boundary curve 6 extends in the second direction and is extended in the third direction.

[0055] S300, obtaining the intersection area of ​​the upper eye sight line 4 of the human-machine, the lower eye sight line 5 of the human-machine and the boundary curve 6, wherein the intersection area is the first arrangement area of ​​the sun visor hinge axis 9.

[0056] In this embodiment, the human-machine upper eye sight line 4, the human-machine lower eye sight line 5 and the boundary curve 6 are arranged to intersect in pairs, that is, the first arrangement area is such that the intersection area can be enclosed together and the sun visor hinge axis 9 can be arranged in the first arrangement area.

[0057] It should be noted that the sun visor hinge axis 9 is extended along the first direction, so the sun visor hinge axis 9 can be preliminarily arranged at any position in the first arrangement area, and the present invention does not impose any limitation on this.

[0058] In the technical solution of the present invention, firstly, according to the human-machine field of view requirements, the human-machine upper eye point 1, the human-machine lower eye point 2 and the head envelope surface 3 are obtained, and then the human-machine upper eye sight line 4 extending along the second direction is established according to the human-machine upper eye point 1, the human-machine lower eye sight line 5 extending along the second direction is established according to the human-machine lower eye point 2, and the boundary curve 6 extending in the third direction is established according to the head envelope surface 3. The human-machine upper eye sight line 4, the human-machine lower eye sight line 5 and the boundary curve 6 intersect each other to enclose each other to form the intersection area, which is the first arrangement area of ​​the sun visor hinge axis 9. With such an arrangement, the feasible area of ​​the sun visor hinge axis arrangement can be quickly checked to avoid repeated attempts and adjustments of the sun visor hinge axis 9, thereby improving efficiency and shortening the cycle.

[0059] Of course, it can be understood that the present invention does not limit the order of establishing the human-machine upper eye sight line 4, establishing the human-machine lower eye sight line 5, and establishing the boundary curve 6. In actual settings, they can be adjusted according to needs.

[0060] It should be noted that, in the present invention, the first direction is the Y-axis direction of the vehicle 100 , the second direction is the X-axis direction of the vehicle 100 , and the third direction is the Z-axis direction of the vehicle 100 .

[0061] In another embodiment of the present invention, the step S200, establishing a human-machine upper eye sight line 4 extending along the second direction according to the human-machine upper eye point 1, establishing a human-machine lower eye sight line 5 extending along the second direction according to the human-machine lower eye point 2, and establishing a boundary curve 6 extending in the third direction according to the head envelope surface 3, at least includes:

[0062] S210, determining a first horizontal reference line extending along a second direction according to the eye point 1 on the human-machine interface;

[0063] It can be understood that the first horizontal reference line is set through the upper eye point 1 of the human-machine interface, and the setting of the first horizontal reference line provides a reference for establishing the upper eye line of the human-machine interface.

[0064] S220, obtaining a human-machine field of view angle in a third direction;

[0065] It should be noted that the present invention does not limit the specific value of the human-machine upper field of view angle. The human-machine upper field of view angle is the angle requirement of the human-machine upper field of view line of the car 100. For different car models, the human-machine upper field of view angle is also different accordingly. Therefore, in actual setting, it can be selected according to the specific car model, and the present invention does not limit this.

[0066] S230, establishing the human-machine upper eye sight line 4 with the first horizontal reference line as a reference and the human-machine upper visual angle as an included angle.

[0067] It can be understood that, in this embodiment, the first horizontal reference line and the human-machine upper eye sight line 4 are both set through the human-machine upper eye point 1, and because the human-machine upper field of view angle is only set in the third direction, the first horizontal reference line and the human-machine upper eye sight line 4 are in the same plane formed by the second direction and the third direction to ensure the accuracy of the human-machine upper eye sight line 4 angle setting.

[0068] It should also be noted that, in the present embodiment, the human-machine upper eye sight line 4 is located on the side of the first horizontal reference line close to the roof of the automobile 100. This arrangement can ensure the extension direction of the human-machine upper eye sight line 4 to further determine the arrangement position of the sun visor hinge axis 9, so that the sun visor 8 can block the sunlight that enters the driver's eyes.

[0069] In the technical solution of this embodiment, the first horizontal reference line is first determined by the eye point 1 on the human machine, and the first horizontal reference line passes through the eye point 1 on the human machine, and then the visual angle of the human machine in the third direction is obtained, and finally, the eye sight line 4 on the human machine is established with the first horizontal reference line as the reference and the visual angle of the human machine as the included angle. Such an arrangement can ensure the accuracy of the extension direction of the eye sight line 4 on the human machine, thereby improving the accuracy of the position of the first arrangement area, so as to improve the arrangement efficiency of the sun visor hinge axis 9.

[0070] In another embodiment of the present invention, the step S200, establishing a human-machine upper eye sight line 4 extending along the second direction according to the human-machine upper eye point 1, establishing a human-machine lower eye sight line 5 extending along the second direction according to the human-machine lower eye point 2, and establishing a boundary curve 6 extending in the third direction according to the head envelope surface 3, at least further includes:

[0071] S240, determining a second horizontal reference line extending along a second direction according to the human-machine lower eye point 2;

[0072] It can be understood that the second horizontal reference line is set through the human-machine lower eye point 2, and the setting of the second horizontal reference line provides a reference for establishing the human-machine lower eye line.

[0073] S250, obtaining the human-machine viewing angle in the third direction;

[0074] It should be noted that the present invention does not limit the specific value of the human-machine lower field of view angle, which is the angle requirement of the human-machine lower field of view line of the car 100. For different car models, the human-machine lower field of view angle is also different accordingly. At the same time, for sun visors 8 with different structural forms and structural sizes, the human-machine lower field of view angle is also different. Therefore, in actual settings, it can be selected according to the specific car model and the structural form of the sun visor 8, and the present invention does not limit this.

[0075] S260, establishing an intermediate sight line 7 with the second horizontal reference line as a reference and the human-machine lower visual angle as an included angle, wherein the sun visor 8 has a lowest point in the third direction during its rotation stroke, and the lowest point is located between the second horizontal reference line and the intermediate sight line 7;

[0076] It can be understood that, in this embodiment, the second horizontal reference line and the intermediate line of sight 7 are both set through the human-machine lower eye point 2, and because the human-machine lower field of view angle is only set in the third direction, the second horizontal reference line and the intermediate line of sight 7 are in the same plane formed by the second direction and the third direction to ensure the accuracy of the angle setting of the intermediate line of sight 7.

[0077] It should also be noted that, in the present embodiment, the middle line of sight 7 is located on the side of the second horizontal reference line close to the roof of the automobile 100. This arrangement can ensure the extension direction of the middle line of sight 7 to further determine the arrangement position of the sun visor hinge axis 9 so that the sun visor 8 can block the sunlight that enters the driver's eyes.

[0078] In addition, in order to ensure that the sun visor 8 can still block the sunlight that shines on the driver's eyes when the driver's eyes are at the lower eye point 2 of the human-machine interface, in this embodiment, the lowest point is set between the second horizontal reference line and the middle line of sight 7.

[0079] S270 , establishing the human-machine lower eye sight line 5 according to the middle sight line 7 .

[0080] It can be understood that the intermediate line of sight 7 is set through the human-machine lower eye point 2, and the intermediate line of sight 7 is close to the lowest point, ensuring that the sunlight will never shine on the driver's glasses. Therefore, the human-machine lower eye line of sight 5 is established based on the intermediate line of sight 7 to accurately determine the position of the first layout area, so as to improve the layout efficiency of the sun visor hinge axis 9.

[0081] In the technical solution of this embodiment, the second horizontal reference line is first determined by the man-machine lower eye point 2, and the second horizontal reference line passes through the man-machine lower eye point 2, and then the man-machine lower visual angle in the third direction is obtained, and then the second horizontal reference line is used as a reference, and the man-machine lower visual angle is used as an angle to establish the intermediate visual line 7, and the midline visual line is located on the side of the lowest point away from the second horizontal reference line to ensure that the sun visor 8 can always block the sunlight shining on the driver's eyes, and finally, the man-machine lower eye sight line 5 is established according to the intermediate visual line 7. Such a setting can ensure the accuracy of the extension direction of the man-machine lower eye sight line 5, thereby improving the accuracy of the position of the first arrangement area, so as to improve the arrangement efficiency of the sun visor hinge axis 9.

[0082] Specifically, in this embodiment, the human-machine eye-down time is A, A≤10°. Such a setting can ensure that the sun visor 8 does not block the driver's normal driving angle of view while ensuring the shielding effect of the sunlight irradiating to the driver's eyes.

[0083] In a further embodiment of the present invention, the step S270 of establishing the human-machine lower eye sight line 5 according to the intermediate sight line 7 includes:

[0084] S271, obtaining the distance between the lowest point and the sun visor hinge axis 9 in the third direction;

[0085] It can be understood that the sun visor hinge axis 9 is located on the side of the lowest point facing the roof of the automobile 100, and the distance between the lowest point and the sun visor hinge axis 9 in the third direction is the size of the sun visor 8 in the third direction.

[0086] S272, translating the intermediate sight line 7 along the third direction according to the distance to establish the human-machine lower eye sight line 5.

[0087] It should be noted that the intermediate line of sight 7 is set corresponding to the lowest point. Therefore, the intermediate line of sight 7 is translated along the third direction by the distance of the spacing so that the translated line of sight corresponds to the sun visor hinge axis 9. In this way, the human-machine lower eye line of sight 5 can be established.

[0088] In the technical solution of this embodiment, the distance between the lowest point and the sun visor hinge axis 9 in the third direction is first obtained, and then the human-machine lower eye intermediate sight line 7 is translated along the third direction according to the distance to establish the human-machine lower eye sight line 5. In this way, the translated sight line is the human-machine lower eye sight line 5, so as to improve the accuracy of the position of the first arrangement area.

[0089] In yet another embodiment of the present invention, the step S200, establishing a human-machine upper eye sight line 4 extending along the second direction according to the human-machine upper eye point 1, establishing a human-machine lower eye sight line 5 extending along the second direction according to the human-machine lower eye point 2, and establishing a boundary curve 6 extending in the third direction according to the head envelope surface 3, at least further comprises:

[0090] S280, obtaining the minimum offset distance of the head envelope surface 3;

[0091] It is understandable that in order to ensure that the driver does not feel oppressive when using the sun visor 8, thereby ensuring the driver's normal usage experience, before establishing the boundary curve 6, it is necessary to determine the minimum offset distance, that is, when the distance between the sun visor hinge axis 9 and the head envelope surface 3 is not less than the minimum offset distance, the sun visor 8 will not feel oppressive to the driver.

[0092] It should be noted that, since the head envelope surface 3 is obtained through the driver's head contour line, in this embodiment, the head envelope surface 3 is specifically a hemispherical surface.

[0093] Of course, the present invention does not limit the specific value of the minimum offset distance. The minimum offset distance can be adjusted according to the structural form and structural size of the sun visor 8. Therefore, in actual setting, it can be selected according to needs.

[0094] In this embodiment, the minimum offset distance is B, and B≥240 mm. This arrangement ensures that the arrangement of the sun visor hinge axis 9 does not cause the driver to feel depressed when using the sun visor 8 .

[0095] S290, expanding the head envelope surface 3 according to the minimum offset distance to obtain a boundary surface;

[0096] It can be understood that, in this embodiment, the head envelope surface 3 is set to be a hemispherical surface, so the boundary surface should also be a hemispherical surface.

[0097] Specifically, in this embodiment, the radius of the head envelope surface 3 is b, and the radius of the boundary surface is b+B.

[0098] S2100: Establish the boundary curve 6 according to the boundary surface.

[0099] It can be understood that the boundary curve 6 is in the same plane as the upper eye sight line 4 of the human-machine and the lower eye sight line 5 of the human-machine.

[0100] In the technical solution of this embodiment, the minimum offset distance of the head envelope surface 3 is first obtained to determine the boundary surface, and the minimum offset distance is the minimum distance between the head envelope surface 3 and the sun visor hinge axis 9. Then, the boundary curve 6 is established according to the boundary surface, so that the boundary curve 6 can enclose the intersection area together with the human-machine upper eye line of sight 4 and the human-machine lower eye line of sight 5, so that the sun visor hinge axis 9 can be arranged within the first arrangement area.

[0101] In a further embodiment of the present invention, the step S2100, establishing the boundary curve 6 according to the boundary surface, comprises:

[0102] S2110 , obtaining a contour line of the boundary surface in the first direction to obtain the boundary curve 6 .

[0103] In the technical solution of this embodiment, since the boundary surface is specifically set as a hemispherical surface, the projection of the boundary surface in the first direction is a semicircular pattern. At this time, the contour line of the boundary surface in the first direction constitutes a curve of the semicircular pattern, and the contour line is the boundary curve 6. At the same time, such a setting can also ensure that the boundary curve 6 and the upper eye sight line 4 of the human-machine and the lower eye sight line 5 of the human-machine are in the same plane.

[0104] In other embodiments of the present invention, after the step S300, obtaining the intersection area of ​​the upper eye sight line 4 of the human-machine, the lower eye sight line 5 of the human-machine and the boundary curve 6, the intersection area is the first arrangement area of ​​the sun visor hinge axis 9, it also includes:

[0105] S400, obtaining a preliminary modeling surface of the ceiling;

[0106] It can be understood that the preliminary shaping surface is the surface shape of the roof in the driving compartment of the automobile 100 .

[0107] S500, acquiring a contour line of the ceiling in a first direction according to the preliminary modeling surface to obtain a ceiling boundary line 10;

[0108] It can be understood that the shape of the step modeling surface in the first direction is usually set in a plane, so the contour line of the ceiling in the first direction can be directly obtained according to the preliminary modeling surface.

[0109] S600 , obtaining an intersection area of ​​the ceiling boundary line 10 , the upper eye sight line 4 of the human-machine, the lower eye sight line 5 of the human-machine, and the boundary curve 6 to obtain a second arrangement area.

[0110] It can be understood that the sun visor hinge needs to be arranged on the ceiling, and in order to ensure the smooth rotation of the sun visor 8, the sun visor hinge axis 9 needs to be arranged at intervals from the ceiling. Therefore, it is necessary to further enclose the second arrangement area based on the ceiling boundary line 10, the human-machine upper eye line of sight 4, the human-machine lower eye line of sight 5 and the boundary curve 6. The second arrangement area is for the arrangement of the sun visor hinge axis 9 to avoid the sun visor hinge axis 9 being arranged inside the ceiling.

[0111] In the technical solution of this embodiment, the preliminary modeling surface is first obtained, and then the ceiling boundary line 10 is established through the preliminary modeling surface. The ceiling boundary line 10, the upper eye sight line 4 of the human-machine, the lower eye sight line 5 of the human-machine, and the boundary curve 6 can be further enclosed to obtain the second layout area. Such a setting can further limit the layout position of the sun visor hinge axis 9, thereby avoiding the sun visor hinge axis 9 from being arranged inside the ceiling, reducing repeated adjustments, and improving the layout efficiency of the sun visor hinge axis 9.

[0112] The present invention also proposes a car 100, which includes a sun visor 8, wherein the sun visor 8 has a sun visor hinge, and the arrangement position of the axis of the sun visor hinge is based on the above-mentioned method for selecting the arrangement position of the sun visor hinge axis.
