Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of automobile sunroof structure design, and in particular relates to a method for checking and evaluating a visible area based on an internal structure of an automobile sunroof. Background Art
[0002] As cars become more popular, users are becoming more critical of their appearance. The sunroof has the function of opening and closing, and there are many internal components. The moving parts and surrounding parts need to be designed with movement gaps, so there is a risk of internal structure leakage. If the internal structure leaks a lot, passengers sitting in the back row of the vehicle can see the leaking structure in the front area, which will reduce the sophistication of the car's appearance, reduce the quality of the vehicle, and reduce the user's desire to consume. Summary of the invention
[0003] In order to overcome the above-mentioned problems, the present invention provides a method for checking and evaluating the visible area of the internal structure of a car sunroof, which is used to check and evaluate the leakage of the internal structure; the visibility of the internal structure of the sunroof is checked during the design stage, possible problems are identified and optimized in advance, and the appearance of the sunroof unit assembly is improved.
[0004] A method for checking and evaluating the visible area of the internal structure of a car sunroof includes the following contents:
[0005] Step 1: Check the skylight viewing area
[0006] Step 1.1, in the vehicle coordinate system, intercept the Y=0 section and draw a straight line that is tangent to the top of the roof and the bottom of the sunshade. This straight line is the line of sight of the passenger observing the maximum visible area of the internal structure of the sunroof, which is defined as straight line A. The area between the intersection of straight line A and the internal structure of the sunroof to the lowest point of the lowest edge of the internal structure of the sunroof is the maximum visible area, hereinafter referred to as area 1, and is defined as dimension a, where a is the distance between the intersection of straight line A and the internal structure of the sunroof to the lowest point of the lowest edge of the internal structure of the sunroof;
[0007] Step 1.2, determine the area within the maximum visible area where sunlight can shine:
[0008] Draw a straight line that passes through the black area of the skylight glass and is tangent to the upper part of the sunshade, which is defined as straight line B. Straight line B is the lowest range line that can be illuminated by sunlight, and the range above straight line B can be illuminated by sunlight; where:
[0009] When the straight line B intersects with the area 1, the area between the intersection and the upper end point of the area 1 is the area actually visible to the passenger, which is defined as the area 2. The dimension b is defined as the distance between the intersection of the straight line B and the area 1 and the upper end point of the area 1.
[0010] When the straight line B does not intersect the area 1, and the straight line B is located below the area 1, it is determined that the area 1 is completely visible, the area 2 overlaps with the area 1, and the size a = size b;
[0011] When the straight line B does not intersect with the area 1, and the straight line B is located above the area 1, it is considered that the area 1 is completely invisible, and the area 2 does not exist at this time, that is, the size b = 0;
[0012] Step 2: Evaluate the skylight viewing area
[0013] When the size of area 2 b = 0, the internal structure of the skylight cannot be perceived by the user, which is the optimal design state;
[0014] When the size b of area 2 is ≤3mm, it is necessary to check whether the skylight structure in area 2 is regular. If the external leakage structure is regular, no optimization is required. If the external leakage structure is uneven or otherwise irregular and affects the user's senses, the internal structure of the skylight needs to be optimized.
[0015] When the size b of area 2 is greater than 3 mm, the internal structure of the skylight needs to be optimized to a size b ≤ 3 mm and a uniform and regular external leakage structure.
[0016] The sunshade is used instead of the sunshade curtain.
[0017] The same applies to non-openable skylights, as long as the skylights are equipped with sunshade structures.
[0018] The sunshade structure is a sunshade curtain or a sunshade board.
[0019] The purpose of intercepting the Y=0 section in step 1 is to perform all steps with the most central section of the vehicle, wherein the Y=0 section is the vertical longitudinal center plane of the vehicle.
[0020] The upper end point of area 1 in step 1.2 is the intersection of straight line A and the internal structure of the skylight.
[0021] Beneficial effects of the present invention:
[0022] In the present invention, the visible area of the sunroof is evaluated by delineating the visible area perceivable by the user within the visible area of the sunroof, so as to check and evaluate the leakage of the internal structure; the visibility of the internal structure of the sunroof is checked in the design stage, possible problems are identified and optimized in advance, and the appearance of the sunroof unit assembly is improved.
[0023] The invention has a wide range of applications and is applicable to both openable skylights and non-openable skylights (skylights) with such a result. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Example 1
[0034] A method for checking and evaluating the visible area of the internal structure of a car sunroof includes the following contents:
[0035] Because the skylight glass is mostly gray tempered glass, and the skylight structure is black or gray, the external light cannot directly illuminate the internal area. Even if there is leakage of the internal structure, the user cannot identify it; therefore, this method evaluates the visible area size of the skylight internal structure and the angle of sunlight, and determines the rationality of the visible area. The verification method is as follows:
[0036] Step 1: Check the skylight viewing area
[0037] Step 1.1, in the vehicle coordinate system, intercept the Y=0 section and make a straight line that is tangent to the top of the roof and the bottom of the sunshade. This straight line is the line of sight of the passenger observing the maximum visible area of the internal structure of the sunroof, defined as straight line A. The line of sight of the maximum visible area, i.e., the area between the intersection of straight line A and the internal structure of the sunroof to the lowest point of the lowest edge of the internal structure of the sunroof, is the maximum visible area, hereinafter referred to as area 1. The size of the maximum visible area is defined as size a, which is the distance between the intersection of straight line A and the internal structure of the sunroof to the lowest point of the lowest edge of the internal structure of the sunroof; see for details. Figure 1 .
[0038] Step 1.2, determine the area within the maximum visible area where sunlight can shine:
[0039] Draw a straight line that passes through the black area of the skylight glass and is tangent to the upper part of the sunshade, which is defined as straight line B. Straight line B is the lowest range line that can be illuminated by sunlight, and the range above straight line B can be illuminated by sunlight; where:
[0040] When straight line B intersects area 1, the area between the intersection and the upper end point of area 1 is the area actually visible to passengers, defined as area 2. Dimension b is defined as the distance between the intersection of straight line B and area 1 and the upper end point of area 1. Figure 2 ;
[0041] When straight line B does not intersect area 1, and straight line B is below area 1, it is determined that area 1 is completely visible, area 2 overlaps area 1, and size a = size b. Figure 3 As shown;
[0042] When the straight line B does not intersect with area 1, and the straight line B is located above area 1, it is considered that area 1 is completely invisible. At this time, there is no area 2, that is, the size b = 0; this state is the optimal design state, such as Figure 4 As shown;
[0043] Step 2: Evaluate the skylight viewing area
[0044] When the size of area 2 b = 0, the internal structure of the skylight cannot be perceived by the user, which is the optimal design state;
[0045] When the size b of area 2 is ≤3mm, it is necessary to check whether the skylight structure in area 2 is regular. If the external structure is a regular plane, no optimization is required. If the external structure is uneven or otherwise irregular and affects the user's senses, the internal structure of the skylight needs to be optimized.
[0046] When the size b of area 2 is greater than 3 mm, the internal structure of the skylight needs to be optimized to the above two states, that is, the size b is less than or equal to 3 mm and the external leakage structure is uniform and regular.
[0047] The sunshade is used instead of the sunshade curtain.
[0048] The same applies to non-openable skylights (curtains), as long as the skylights are equipped with sunshade structures.
[0049] The sunshade structure is a sunshade curtain or a sunshade board.
[0050] The purpose of intercepting the Y=0 section in step 1 is to perform all steps with the most central section of the vehicle, wherein the Y=0 section is the vertical longitudinal center plane of the vehicle.
[0051] The upper end point of area 1 in step 1.2 is the intersection of straight line A and the internal structure of the skylight.
[0052] Example 2
[0053] 1. Check the visible area of the skylight
[0054] In the vehicle coordinate system, intercept the Y=0 section and draw a straight line that is tangent to the ceiling boundary and the sunshade boundary at the same time. This straight line is the line of sight of the maximum visible area of the sunroof internal structure for passengers, which is defined as straight line A. The area below the intersection of the maximum visible area line of sight and the sunroof internal structure, until the bottom edge of the internal structure is the maximum visible area, hereinafter referred to as area ①. The size of the maximum visible area is defined as size a;
[0055] Determine the area within the maximum visible area that can be illuminated by sunlight. Draw a straight line that passes through the boundary of the black area of the sunroof glass and is tangent to the upper part of the sunshade, and define it as straight line B. Straight line B is the lowest range that can be illuminated by sunlight, and the range above straight line B can be illuminated by sunlight. When straight line B and area ① have an intersection, the area determined by the intersection and the upper end point of area ① is the area that passengers can actually see, defined as area ②, and its size is defined as size b. See below for details. Figure 2 .
[0056] When straight line B and area ① do not intersect, and straight line B is below area ①, it is determined that area ① is fully visible, area ② = area ①, and size a = size b. Figure 3 shown.
[0057] When the straight line B and area ① do not have an intersection, and the straight line B is located above area ①, it is considered that area ① is completely invisible. At this time, there is no area ②, that is, the size b = 0. This state is the optimal design state, as follows Figure 4 shown.
[0058] Second, evaluate the skylight viewing area
[0059] When the size b of area ② is 0, it is considered that the internal structure of the skylight cannot be perceived by the user, which is the optimal design state.
[0060] When the size b of region ② is ≤3, it is necessary to check whether the structure inside region ② is regular. If the external leakage structure is a regular plane, no optimization is required. If the external leakage structure is uneven or has other non-planar states, the structure needs to be optimized.
[0061] When the size b of area ② is greater than 3, the skylight structure needs to be optimized to the above-mentioned state 2, that is, the size b≤3 and the external leakage structure is uniform and regular.
