[0002] With the progress of automobile manufacturing technology, consumers' requirements for vehicle driving comfort are continuously improved, and sun visors emerge as the times require. The sun visor is an assembly of a plate-shaped component (body) and an installation component (a component for installing and supporting the sun visor, which is composed of a support, a rotating shaft and other parts) arranged to block dazzling light into the eyes of the driver (including the co-driver and the passenger). The sun visor is a frequently used interior functional part in daily use, and the use experience directly affects the user's intuitive experience of the quality of the automobile. In order to improve the user experience, the related art makes a recess design on the roof to avoid space and facilitate the use of the passenger.

[0003] The larger the gap between the sun visor and the roof, the more convenient it is for the passenger to operate, but the larger the gap between the sun visor and the roof and the larger the gap, the worse the appearance and the feeling, which causes the designer to have a dilemma when designing the roof structure at the hand operating space. And when the practitioner designs the cross section of the roof and the sun visor, it is found that there is no unified design method for the roof structure suitable for all types of sun visors due to the variety of sun visors. This leads to repeated and redundant design work of the roof structure at the sun visor hand operating space during the development of the automobile, resulting in an increase in research and development costs.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0034] The embodiments of the present application will be further described below with reference to the drawings. In view of the lack of a standardized design method for the sun visor and the ceiling in the prior art, which leads to repeated and redundant design of the sun visor hand-operating space cross-sectional structure, and causes the research and development time cost to rise, as shown in Figure 1 and Figure 2 The present application provides a design method for the ceiling structure at the hand-operating space of a sun visor, which comprises the following steps:

[0035] S1. An analysis model is established, and the position and shape of the sun visor 1 at the hand-operating space in a non-use state are determined.

[0036] It should be noted that the non-use state refers to the state in which the sun visor 1 is covered on the ceiling 2, and the user needs to move the sun visor 1 by putting his hand into the hand-operating space to switch it to a use state.

[0037] S2. An inner recess structure is arranged on the inner surface of the ceiling 2, so that the groove bottom surface 21 and the groove side wall surface 22 are in position correspondence with the inner surface 11 and the top arc surface 12 of the sun visor 1, respectively.

[0038] It can be understood that, Figure 1 and Figure 2 is a cross-sectional view of the hand-operating space in the X direction of the present application, Figure 3 is a whole structure diagram of the sun visor 1 and the ceiling 2 in the height direction, as shown in Figure 3 there is a gap between the ceiling 2 and the sun visor 1. The hand-operating space is a convenient structure designed by the practitioner to facilitate the driver or the co-pilot to flip the sun visor 1. As shown in Figure 3As shown, the operator's hand can extend into the hand-operating space along the Z direction (i.e. the height direction) of the automobile, and then turn the sun visor 1. The hand-operating space is designed to ensure that the operator's hand can extend into the space without affecting the appearance of the gap between the roof 2 and the sun visor 1.

[0039] It should be noted that, as Figure 2 shown, the X direction is the length direction of the automobile, the Y direction is the width direction of the automobile, and the Z direction is the height direction of the automobile.

[0040] It can be understood that the recessed structure along the Z direction is arranged at the part of the roof 2 in the hand-operating space. As Figure 1 shown, the surface of the recessed structure of the roof 2 is divided into a groove bottom surface 21, a groove side wall surface 22, and a groove edge surface 23. The groove bottom surface 21 is the bottom surface of the recessed structure of the roof 2, the groove side wall surface 22 is the side wall surface of the recessed structure, and the groove edge surface 23 is the edge surface of the opening of the recessed structure.

[0041] Further, as Figure 1 shown, the contact point between the sun visor 1 and the roof 2 in the non-use state is an edge contact point 111. Preferably, in order to ensure that the passenger has enough space when using, the fingers are prevented from being poked into the roof to cause discomfort. The vertical distance between the edge contact point 111 and the center point of the groove bottom surface 21 in the Y direction is between 30 mm and 60 mm, and is preferably 45 mm.

[0042] It should be noted that the length of the groove bottom surface in the X direction is set to be between 20 mm and 40 mm, and is preferably 25 mm.

[0043] S3. The vertical distance between the inner surface 11 of the sun visor 1 and the groove bottom surface 21 and the vertical distance between the top arc surface 12 of the sun visor 1 and the groove side wall surface 22 are kept within a predetermined range.

[0044] Specifically, the vertical distance between the inner surface 11 of the sun visor 1 and the groove bottom surface 21 is kept between 12 mm and 20 mm. Preferably, the distance between the inner surface 11 of the sun visor 1 and the groove bottom surface 21 is set to be 15 mm, which can ensure better operation experience.

[0045] Further, the vertical distance between the top arc surface 12 of the sun visor 1 and the groove side wall surface 22 is kept between 12 mm and 20 mm. Preferably, the maximum vertical distance between the top arc surface 12 of the sun visor 1 and the groove side wall surface 22 is set to be 15 mm.

[0046] After multiple tests, the roof 2 is designed according to the above-mentioned preset distance, which has high applicability and can meet the structures of various sunshields 1.

[0047] Optionally, the length of the groove bottom surface 21 in the X direction is set to be between 20 mm and 40 mm, and the distance between the edge contact point 111 of the inner surface 11 and the midpoint of the groove bottom surface 21 in the X direction is set to be between 40 mm and 50 mm.

[0048] Preferably, the length of the groove bottom surface 21 in the X direction is set to be 25 mm, and the distance between the edge contact point 111 of the inner surface 11 and the midpoint of the groove bottom surface 21 in the X direction is set to be 45 mm.

[0049] In some specific embodiments, the included angle between the groove side wall surface 22 and the groove bottom surface 21 is set to be between 120° and 150°. Preferably, the included angle between the groove side wall surface 22 and the groove bottom surface 21 is set to be 120°.

[0050] Optionally, the included angle between the groove bottom surface 21 and the groove side wall surface 22 is rounded. The included angle between the groove side wall surface 22 and the groove edge surface 23 is rounded.

[0051] S4. The groove edge surface 23 is kept above the outer surface 13 of the sunshade 1 in the automobile Z direction. Optionally, the groove edge surface 23 is arranged in parallel with the outer surface 13 of the sunshade 1, so that the external appearance is improved.

[0052] It can be understood that the perpendicular distance between the groove edge surface 23 and the outer surface 13 of the sunshade 1 in the automobile Z direction is between 2.5 mm and 7.5 mm.

[0053] Preferably, the perpendicular distance between the groove edge surface 23 and the outer surface 13 of the sunshade 1 in the automobile Z direction is 5 mm.

[0054] It can be understood that the groove edge surface 23 is kept above the outer surface 13 of the sunshade 1 in the automobile Z direction, so that the fingers of the user using the sunshade 1 will not be interfered by the groove edge surface 23.

[0055] S5. The entire roof 2 is drawn.

[0056] It can be understood that the drawing of the sunshade handle space roof has been completed in steps S1-S4, and the entire roof 2 is drawn, and the standard section of the sunshade handle space roof is obtained.

[0057] Furthermore, this application also provides a canopy structure for the manual operation space of a sunshade manufactured using the above-described design method, comprising: a canopy 2 and a sunshade 1; wherein,

[0058] The sun visor 2 has a concave structure on its inner surface. The bottom surface 21 and the side wall surface 22 of the concave structure correspond sequentially to the inner surface 11 and the top arc surface 12 of the sun visor 1. The vertical distance between the inner surface 11 of the sun visor 1 and the bottom surface 21 of the concave structure is maintained between 12mm and 20mm. The vertical distance between the top arc surface 12 of the sun visor 1 and the side wall surface 22 of the concave structure is also maintained between 12mm and 20mm. The edge surface 23 of the concave structure is positioned above the outer surface 13 of the sun visor 1 in the Z-direction of the vehicle.

[0059] It is understandable that, such as Figure 3 As shown, there is a gap between the canopy 2 and the sun visor 1. The handrail space is a convenient structure designed for the driver or co-driver to easily flip the sun visor 1. Figure 3 As shown, the operator's hand can reach into the hand-operated space along the Z-direction (i.e., the height direction) of the car and enter between the roof 2 and the sun visor 1, and then rotate the sun visor 1. The reason for designing the hand-operated space in this application is to maintain the gap between the roof 2 and the sun visor 1 to meet the customer's aesthetic and tactile requirements without hindering the operator's hand from reaching in.

[0060] It is understandable that a concave structure along the Z-direction is provided at the location of the canopy 2 in the hand-operated space. This application, as described... Figure 1 As shown, the surface of the concave structure of the ceiling 2 is divided into a groove bottom surface 21, a groove side wall surface 22, and a groove edge surface 23. Among them, the groove bottom surface 21 is the bottom surface of the concave structure of the ceiling 2, the groove side wall surface 22 is the side wall surface of the concave structure, and the groove edge surface 23 is the edge surface of the opening of the concave structure.

[0061] Furthermore, such as Figure 1 As shown, the contact point between the sun visor 1 and the roof 2 when not in use is the edge contact point 111. Preferably, to ensure sufficient space for passengers during use and to avoid discomfort caused by fingers poking into the roof, the vertical distance between the edge contact point 111 and the center point of the groove bottom surface 21 in the Y direction is between 40mm and 50mm, preferably 45mm.

[0062] It is worth noting that the length of the bottom surface of the groove in the X direction is set between 20mm and 40mm, preferably 25mm.

[0063] In a preferred embodiment, the vertical distance between the inner surface 11 of the sunshade 1 and the bottom surface 21 of the groove is set to 15mm. At the same time, the maximum vertical distance between the top arc surface 12 of the sunshade 1 and the side wall surface 22 of the groove is also set to 15mm, which can ensure a better operating experience.

[0064] In an optional embodiment, the length of the groove bottom surface 21 in the X direction is set between 20mm and 40mm, and the distance between the edge contact point 111 of the groove bottom surface 21 and the inner surface 11 and the midpoint of the groove bottom surface 21 in the X direction is set between 30mm and 60mm.

[0065] In a preferred embodiment of this application, the length of the groove bottom surface 21 in the X direction is set to 25mm, and the distance in the X direction between the edge contact point 111 of the groove bottom surface 21 and the inner surface 11 and the midpoint of the groove bottom surface 21 is set to 45mm.

[0066] In some specific embodiments, the angle between the groove sidewall 22 and the groove bottom surface 21 is set between 120° and 150°. Preferably, the angle between the groove sidewall 22 and the groove bottom surface 21 is set to 120°.

[0067] Optionally, the included angle between the bottom surface 21 of the groove and the side wall surface 22 of the groove is rounded. The included angle between the side wall surface 22 of the groove and the edge surface 23 of the groove is rounded.

[0068] It is understood that the vertical distance between the groove edge surface 23 and the outer surface 13 of the sun visor 1 in the Z direction of the vehicle is between 2.5 mm and 7.5 mm.

[0069] Preferably, the vertical distance between the groove edge surface 23 and the outer surface 13 of the sun visor 1 in the Z direction of the vehicle is 5mm.

[0070] It is understood that the groove edge surface 23 is positioned above the outer surface 13 of the sun visor 1 in the Z direction of the vehicle, so that the user's fingers will not be interfered with by the groove edge surface 23 when using the sun visor 1.

[0071] On the other hand, this application provides a car that includes a roof structure for the sun visor manual operating space, comprising: a roof 2 and a sun visor 1; wherein,

[0072] The sun visor 2 has a concave structure on its inner surface. The bottom surface 21 and the side wall surface 22 of the concave structure correspond sequentially to the inner surface 11 and the top arc surface 12 of the sun visor 1. The vertical distance between the inner surface 11 of the sun visor 1 and the bottom surface 21 of the concave structure is maintained between 12mm and 20mm. The vertical distance between the top arc surface 12 of the sun visor 1 and the side wall surface 22 of the concave structure is also maintained between 12mm and 20mm. The edge surface 23 of the concave structure is positioned above the outer surface 13 of the sun visor 1 in the Z-direction of the vehicle.

[0073] It is understandable that, such as Figure 3 As shown, there is a gap between the canopy 2 and the sun visor 1. The handrail space is a convenient structure designed for the driver or co-driver to easily flip the sun visor 1. Figure 3 As shown, the operator's hand can reach into the hand-operated space along the Z-direction (i.e., the height direction) of the car and enter between the roof 2 and the sun visor 1, and then rotate the sun visor 1. The reason for designing the hand-operated space in this application is to maintain the gap between the roof 2 and the sun visor 1 to meet the customer's aesthetic and tactile requirements without hindering the operator's hand from reaching in.

[0074] It is understandable that a concave structure along the Z-direction is provided at the location of the canopy 2 in the hand-operated space. This application, as described... Figure 1 As shown, the surface of the concave structure of the ceiling 2 is divided into a groove bottom surface 21, a groove side wall surface 22, and a groove edge surface 23. Among them, the groove bottom surface 21 is the bottom surface of the concave structure of the ceiling 2, the groove side wall surface 22 is the side wall surface of the concave structure, and the groove edge surface 23 is the edge surface of the opening of the concave structure.

[0075] Furthermore, such as Figure 1 As shown, the contact point between the sun visor 1 and the roof 2 when not in use is the edge contact point 111. Preferably, to ensure sufficient space for passengers during use and to avoid discomfort caused by fingers poking into the roof, the vertical distance between the edge contact point 111 and the center point of the groove bottom surface 21 in the Y direction is between 30mm and 60mm, preferably 45mm.

[0076] It is worth noting that the length of the bottom surface of the groove in the X direction is set between 20mm and 40mm, preferably 25mm.

[0077] In a preferred embodiment, the vertical distance between the inner surface 11 of the sunshade 1 and the bottom surface 21 of the groove is set to 15mm. At the same time, the maximum vertical distance between the top arc surface 12 of the sunshade 1 and the side wall surface 22 of the groove is also set to 15mm, which can ensure a better operating experience.

[0078] In an optional embodiment, the length of the groove bottom surface 21 in the X direction is set between 20mm and 40mm, and the distance between the edge contact point 111 of the groove bottom surface 21 and the inner surface 11 and the midpoint of the groove bottom surface 21 in the X direction is set between 30mm and 60mm.

[0079] In a preferred embodiment of this application, the length of the groove bottom surface 21 in the X direction is set to 25mm, and the distance in the X direction between the edge contact point 111 of the groove bottom surface 21 and the inner surface 11 and the midpoint of the groove bottom surface 21 is set to 45mm.

[0080] In some specific embodiments, the angle between the groove sidewall 22 and the groove bottom surface 21 is set between 120° and 150°. Preferably, the angle between the groove sidewall 22 and the groove bottom surface 21 is set to 120°.

[0081] Optionally, the included angle between the bottom surface 21 of the groove and the side wall surface 22 of the groove is rounded. The included angle between the side wall surface 22 of the groove and the edge surface 23 of the groove is rounded.

[0082] It is understood that the vertical distance between the groove edge surface 23 and the outer surface 13 of the sun visor 1 in the Z direction of the vehicle is between 2.5 mm and 7.5 mm.

[0083] Preferably, the vertical distance between the groove edge surface 23 and the outer surface 13 of the sun visor 1 in the Z direction of the vehicle is 5mm.

[0084] It is understood that the groove edge surface 23 is positioned above the outer surface 13 of the sun visor 1 in the Z direction of the vehicle, so that the user's fingers will not be interfered with by the groove edge surface 23 when using the sun visor 1.

[0085] It is understandable that the above embodiments regarding the ceiling structure only constrain its Y-direction cross-section. However, as a component perceived by the customer, its dimensions also need to be considered in a 3D rendering. Figure 3 As shown, in the cross-section of the ceiling structure in the Z direction (i.e., the height direction), the Y-direction dimension of the straight segment of the ceiling 2 in the hand-operated space must be ≥50mm. That is, the cross-section of the groove edge surface 23 in the height direction is also a groove structure, and its bottom is a straight segment, the length of which must be ≥50mm.

[0086] In related technologies, such as Figure 4 As shown, there are irregularly shaped sunshades, such as... Figure 4 As shown, the irregularly shaped sunshade in the hand-operated space is difficult to adapt to the non-standardized design of the canopy structure, which can easily cause problems such as pinching hands and difficulty in opening, leading to operational difficulties.

[0087] And suchFigure 5 As shown, the canopy structure manufactured using the design method of this application has a vertical distance of 45 mm in the Y direction between the edge contact point 111 and the center point of the groove bottom surface 21. The minimum vertical distance between the groove bottom surface 21 and the inner surface 11 of the sun visor 1 is 15 mm, and the angle between the groove bottom surface 21 and the groove sidewall surface 22 is 140°. The groove edge surface 23 is higher than the outer surface 13 of the sun visor 1, and the vertical distance between the two is 5 mm. Through actual use and calculation, the canopy structure manufactured using the standardized design method of this application can solve the problems of hand pinching and difficulty in opening. Therefore, it can be seen that the design method of this application has high versatility, and the canopy structure can adapt to sun visors with various irregular shapes.

[0088] In summary, this invention provides a design method for the cross-sectional structure of the manual operation space of a sun visor. By optimizing each corresponding surface of the roof in the manual operation space, it solves the problem of balancing vehicle appearance quality and customer operating experience. It avoids repeated adjustments to the sun visor assembly or large-scale modifications to the roof during the vehicle testing phase, effectively reducing R&D costs. Furthermore, the design method of this application has high versatility and can be applied to sun visors with various irregular shapes.
