[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0030] In current market vehicles, the driver can usually see through the internal electrical components through the heat dissipation grille of the inner rearview mirror decorative cover. This structure is usually not acceptable to users and reduces the overall vehicle perception quality. If optimization is carried out after the inner rearview mirror decorative cover is actually produced, certain mold scrapping costs will be incurred, increasing the product cost of the inner rearview mirror decorative cover. Based on this, the embodiments of the present invention provide a grille verification method, device, and electronic device for an inner rearview mirror decorative cover. This technology can be applied to applications that require optimizing the design of the inner rearview mirror decorative cover.

[0031] To facilitate the understanding of this embodiment, first, a grille verification method for an inner rearview mirror decorative cover disclosed in the embodiments of the present invention is introduced. This method provides the model design data of the vehicle through an electronic device, which can be a computer, a tablet computer, etc.; the model design data of the vehicle can include data such as the component models, dimensions, and materials of the vehicle; as Figure 1 shown, the method includes the following steps:

[0032] Step S102, in response to a model display instruction for the model design data, display the eye graphics of a virtual user and the cover model of the inner rearview mirror decorative cover through a model three-dimensional display interface; the cover model includes a grille area for dissipating heat from the electrical components inside the inner rearview mirror decorative cover.

[0033] The above model three-dimensional display interface refers to a graphical user interface for displaying three-dimensional models, which allows users to view and interact with three-dimensional models in a visual way; the above virtual user can be a simulated driver or a user in the simulated co-pilot position, etc.; the above eye graphics usually include a left eye graphic and a right eye graphic, where the left eye graphic represents the statistical distribution area of the left eye viewpoints of multiple different users, and the right eye graphic represents the statistical distribution area of the right eye viewpoints of multiple different users; the above electrical components can include a light and rain sensor, an anti-fog sensor, an ACC camera, etc.; the above grille area can be distributed on the lower surface, left surface, right surface, etc. of the cover model, and the grille shape in the grille area can be a rectangular grille, a circular grille, a polygonal grille, etc., which can be specifically set according to actual needs and will not be limited here.

[0034] In actual implementation, during the process of a user designing the inner rearview mirror garnish, the electronic device can provide the model design data of the vehicle. The user can issue a model display instruction for the model design data by operating the electronic device. In response to this model display instruction, the electronic device can display the eye graphics of the virtual user and the garnish model of the inner rearview mirror through the model three-dimensional display interface. The garnish model includes a grille area for the heat dissipation of the electrical components inside the inner rearview mirror garnish. It should be noted that the relative positions of the eye graphics and the garnish model displayed in the model three-dimensional display interface simulate the relative positions between the user sitting in the driver's seat or the passenger seat and the actual inner rearview mirror device garnish installed on the front windshield in the real scenario. Therefore, in the model design stage, the grille area of the garnish model can be optimized through the displayed eye graphics and the garnish model.

[0035] Step S104, in response to the connection operation for the eye graphics and the grille area, display the left-eye connection line and the right-eye connection line through the model three-dimensional display interface; wherein, the left-eye connection line is a straight line from the left-eye graphic in the eye graphics to the first grid edge in the grille area, and the right-eye connection line is a straight line from the right-eye graphic in the eye graphics to the second grid edge in the grille area.

[0036] The above grille area usually includes multiple grid edges. Two appropriate grid edges can be selected from the multiple grid edges according to actual needs and used as the above-mentioned first grid edge and second grid edge respectively. In actual implementation, after the eye graphics and the garnish model are displayed in the model three-dimensional display interface, the user can draw a straight line from the left-eye graphic to the first grid edge as the left-eye connection line. The number of the left-eye connection lines can be one or more. For example, taking the first grid edge as a rectangle, multiple points can be selected on the upper edge of the first grid edge, and straight lines are drawn from the left-eye graphic to each point respectively to obtain multiple left-eye connection lines. Similarly, the user can draw a straight line from the right-eye graphic to the second grid edge as the right-eye connection line. The number of the right-eye connection lines can be one or more. For example, taking the second grid edge as a rectangle, multiple points can be selected on the upper edge of the second grid edge, and straight lines are drawn from the right-eye graphic to each point respectively to obtain multiple right-eye connection lines.

[0037] Step S106, check the grille area of the garnish model according to the intersection positions of the left-eye connection line and the right-eye connection line with the garnish model respectively.

[0038] The above intersection position may be located on the outer surface of the cover model or on the inner surface of the cover model, etc. For example, if the intersection position of the left-eye connection line and the cover model is located on the inner surface of the cover model, it can be considered that the interior of the cover model can be seen along the line-of-sight direction indicated by the left-eye connection line; if the intersection position of the left-eye connection line and the cover model is located on the outer surface of the cover model, it can be considered that the interior of the cover model cannot be seen along the line-of-sight direction indicated by the left-eye connection line. In actual implementation, the grille area of the cover model can be inspected or adjusted according to the intersection positions of the left-eye connection line and the right-eye connection line with the cover model respectively, so that the adjusted grille area has the function of preventing see-through while ensuring the ventilation and heat dissipation requirements.

[0039] The above grille checking method for the inner rearview mirror cover provides model design data through an electronic device, and then can respond to a model display instruction for the model design data to display the eye graphics of the virtual user and the cover model of the inner rearview mirror cover through the model three-dimensional display interface; the cover model includes a grille area for dissipating heat of the electrical components inside the inner rearview mirror cover. By checking the grille area of the inner rearview mirror cover in the model design stage, the checking efficiency can be improved and the development cost can be reduced; by displaying the eye graphics and the above cover model through the model three-dimensional display interface, it is convenient for the user to respond to the connection operation for the eye graphics and the grille area, and then display the left-eye connection line and the right-eye connection line in the model three-dimensional display interface. And the method of checking the grille area of the cover model according to the intersection positions of the left-eye connection line and the right-eye connection line with the cover model respectively can check the shielding degree of the inner rearview mirror cover in the vehicle on its internal electrical components, and then guide the adjustment of the cover model of the inner rearview mirror cover in the model design stage to improve the perceived quality of the inner rearview mirror cover.

[0040] The embodiment of the present invention also provides another grille checking method for the inner rearview mirror cover. This method is implemented on the basis of the method of the above embodiment. In this method, the eye graphics are located on the left side of the cover model; in this embodiment, taking the virtual user as a simulated driver as an example, considering that in the actual scenario, the inner rearview mirror cover is usually fixed on the front windshield and the driver is located on the left side of the vehicle, therefore, the eye graphics displayed in this embodiment are located on the left side of the cover model; the method includes the following steps:

[0041] Step 1, respond to an eye point display instruction for the model design data, and display the eye point graphics of the virtual user through the model three-dimensional display interface; wherein, the eye point graphics are used to represent the eye reference position.

[0042] The above-mentioned eye point pattern usually includes a left eye point and a right eye point, which are generally used to represent the reference position of the eyes; the position of the eye point pattern can be determined in the following way: through the R point of the driver's seat, a plane parallel to the longitudinal reference plane of the vehicle is made. At a point 635 mm above the R point of the driver's seat within this plane, a straight line perpendicular to this plane is made. At two points 32.5 mm on each side of the intersection point of the straight line and this plane (i.e., the total distance between the two points is 65 mm), the point on the left side of the intersection point is the left eye point, and the point on the right side of the intersection point is the right eye point. The left eye point and the right eye point can be used to assist in checking whether the driver can see the internal structure through the grille of the interior rearview mirror housing; the above-mentioned R point is the design reference point for the occupant's seating specified by the manufacturer, and can also be understood as a reference point for defining the standard position of the driver's seat, or, can also be understood as the ideal center point of the driver's sitting posture. The method for determining the eye point pattern can refer to the prior art and will not be elaborated here. In specific implementation, the user can operate the electronic device to issue an eye point display instruction for the model design data, and the electronic device responds to this eye point display instruction, and then can display the eye point pattern of the virtual user through the model three-dimensional display interface.

[0043] Step 2, in response to the eye pattern display operation, display the eye pattern generated according to the eye point pattern; wherein, the eye pattern is used to characterize the eye distribution positions of multiple different virtual users;

[0044] In practical applications, due to the different body sizes of people, different drivers sitting in the driver's seat in a normal driving posture will obviously have different eye positions. By applying statistical viewpoints and methods to study the distribution law of the driver's viewpoints, it is found that the viewpoint distribution pattern of vehicle drivers is elliptical, that is, both the displayed left eye pattern and right eye pattern are elliptical. Therefore, the left eye pattern in the above-mentioned eye pattern can also be called the left eye ellipse, and the right eye pattern can also be called the right eye ellipse; in actual implementation, after the eye point pattern is displayed in the model three-dimensional display interface, the user can operate the electronic device to perform the above-mentioned eye pattern display operation, and the electronic device responds to this eye pattern display operation, and then can generate the eye pattern according to this eye point pattern. For example, a left eye pattern can be drawn with the left eye point as the center, and a right eye pattern can be drawn with the right eye point as the center, and the generated left eye pattern and right eye pattern are displayed through the model three-dimensional display interface.

[0045] Step 3, in response to the housing model display operation, display the housing model of the interior rearview mirror housing through the model three-dimensional display interface;

[0046] The user can operate the electronic device to perform the above-mentioned housing model display operation, and the electronic device responds to this housing model display operation, and then can display the housing model of the interior rearview mirror housing in the model three-dimensional display interface.

[0047] Step 4, in response to the connection operation for the left-eye graphic and the grille area in the eye graphic, display, through the model three-dimensional display interface, the left-eye connection line from the first specified point of the left-eye graphic to the first grid edge in the grille area; where the first specified point is the point on the left-eye graphic that is closest to the front of the vehicle.

[0048] In actual implementation, the point closest to the front of the vehicle can be found on the displayed left-eye graphic as the above-mentioned first specified point. The user operates the electronic device to perform the above connection operation. The electronic device responds to this connection operation, and can then connect from the first specified point to the first grid edge to obtain the above-mentioned left-eye connection line, which is displayed in the model three-dimensional display interface.

[0049] As a preferred implementation, the left-eye connection line is a straight line from the first specified point to the first connection point on the first grid edge; the first connection point is the end point on the first grid edge that is closest to the first specified point; the first grid edge is the grid edge on the left grille area of the hood model that is closest to the first specified point.

[0050] In actual implementation, since the eye graphic is located on the left side of the hood model, considering the viewing habit, the angle between the left grille area of the hood model and the left-eye graphic, and the angle between the left grille area of the hood model and the right-eye graphic, it can be understood that, relative to the right-eye graphic, the left-eye graphic is more likely to see the interior of the hood model through the left grille area, and the closer the grille is to the first specified point of the left-eye graphic, the more likely the left-eye graphic is to see the interior of the hood model through this grille. Therefore, the first grid edge closest to the first specified point can be found on the left grille area of the hood model, and the end point on this first grid edge that is closest to the first specified point is used as the first connection point. This first connection point is usually the end point corresponding to the first grid on the left grille area that is closest to the first specified point. A straight line is drawn from the first specified point on the left-eye graphic to the first connection point to obtain the above-mentioned left-eye connection line.

[0051] Step 5, in response to the connection operation for the right-eye graphic and the grille area in the eye graphic, display, through the model three-dimensional display interface, the right-eye connection line from the second specified point of the right-eye graphic to the second grid edge in the grille area; where the second specified point is the point on the right-eye graphic that is closest to the front of the vehicle.

[0052] In actual implementation, the point closest to the front of the vehicle can be found on the displayed right-eye graphic as the above-mentioned second specified point. The user operates the electronic device to perform the above connection operation. The electronic device responds to this connection operation, and can then connect from the second specified point to the second grid edge to obtain the above-mentioned right-eye connection line, which is displayed in the model three-dimensional display interface.

[0053] As a preferred implementation, the right-eye connection line is a straight line between the second specified point and the second connection point on the second grid edge; the second connection point is the end point on the second grid edge that is closest to the second specified point; the second grid edge is the grid edge on the lower-side grid area of the cover model that is closest to the second specified point.

[0054] In actual implementation, since the eye graphic is located on the left side of the cover model, considering the visual field habit, the angle between the lower-side grid area of the cover model and the left-eye graphic, and the angle between the lower-side grid area of the cover model and the right-eye graphic, it can be understood that, relative to the left-eye graphic, the right-eye graphic is more likely to see the interior of the cover model through the lower-side grid area, and, for the grids closer to the second specified point of the right-eye graphic, the right-eye graphic is more likely to see the interior of the cover model through that grid. Therefore, the second grid edge that is closest to the second specified point can be found on the lower-side grid area of the cover model, and the end point that is closest to the second specified point on this second grid edge is used as the second connection point. This second connection point is usually the end point corresponding to the first grid that is closest to the second specified point on the lower-side grid area. A straight line is drawn from the second specified point on the right-eye graphic to the second connection point to obtain the above-mentioned right-eye connection line.

[0055] Step Six, if the intersection position of the left-eye connection line and the cover model is not on the outer surface of the cover model, and / or the intersection position of the right-eye connection line and the cover model is not on the outer surface of the cover model, check and verify the grid area of the cover model.

[0056] If the intersection position of the left-eye connection line and the cover model is not on the outer surface of the cover model, it can be considered that the left-eye graphic can see the internal structure through the left-side grid area of the cover model. In this case, usually, the left-side grid area of the cover model needs to be checked and adjusted; for example, if the left-eye connection line passes through the left-side grid area and enters the interior of the cover model, and the intersection position is on the inner surface of the cover model, then the left-side grid needs to be checked and adjusted.

[0057] If the intersection position of the right-eye connection line and the cover model is not on the outer surface of the cover model, it can be considered that the right-eye graphic can see the internal structure through the lower-side grid area of the cover model. In this case, usually, the lower-side grid area of the cover model needs to be checked and adjusted; for example, if the right-eye connection line passes through the lower-side grid area and enters the interior of the cover model, the intersection position may reach the surface of the electrical components inside the cover model, then the lower-side grid area needs to be checked and adjusted.

[0058] The steps for checking and verifying the grid area of the cover model described above include: in response to a grid checking and verifying instruction, check and verify the grid area of the cover model; where the grid checking and verifying instruction is used to indicate: adjusting the shape, size, and / or inclination angle of the grids in the grid area.

[0059] In actual implementation, the user can operate the electronic device to issue the above grille checking instruction. After the electronic device receives the grille checking instruction, it can adjust the shape, size, and / or tilt angle of the grille in the grille area according to the grille checking instruction. For example, taking the grille in the grille area as a rectangular grille, the rectangular grille can be adjusted to a circular grille, the size of the rectangular grille can be enlarged or reduced, or the tilt angle of the grid edges forming the rectangular grille can be adjusted, etc. By checking the grille area of the cover model, the checked grille area can meet the requirement of not being seen through.

[0060] It should be noted that the inner rearview mirror cover usually adopts a left-right symmetric design structure. Therefore, the grille area on the right side of the cover model usually adopts the same design as the grille area on the left side, so that the user in the co-pilot position can also not see the electrical components inside the inner rearview mirror cover.

[0061] For easy understanding, refer to Figure 2 the schematic diagram of a three-dimensional display interface of a model shown in the figure. First, according to the vehicle body design requirements, find the left eye point P1 and the right eye point P2 when the driver is driving the vehicle. Among them, the vehicle body design requirements can include requirements such as vehicle length, vehicle width, vehicle height, and the requirements of the heel point. The heel point can be understood as the position point of the heel when the driver's foot touches the vehicle floor or pedal. Then draw the left eye ellipse S1 according to the left eye point P1, and draw the right eye ellipse S2 according to the right eye point P2. As Figure 3 shown in the schematic diagram of another three-dimensional display interface of a model in the figure, find the point P3 closest to the front of the vehicle on the right eye ellipse S2 (corresponding to the above-mentioned second specified point), and draw a tangent line L1 from the point P3 to the first grille at the lower part of the cover model of the inner rearview mirror cover (corresponding to the above-mentioned right eye connection line being the straight line between the second specified point and the second connection point on the second grid edge), and check whether the internal structure will be seen through when a heat dissipation grille is opened below the inner rearview mirror cover according to the line of sight direction indicated by the tangent line L1; as Figure 4 shown in the schematic diagram of another three-dimensional display interface of a model in the figure, find the point P4 closest to the front of the vehicle on the left eye ellipse S1, and draw a tangent line L2 from the point P4 to the first grille on the left side of the cover model of the inner rearview mirror cover (corresponding to the above-mentioned left eye connection line being the straight line between the first specified point and the first connection point on the first grid edge), and check whether the internal structure will be seen through when a heat dissipation grille is opened on the left side of the inner rearview mirror cover according to the line of sight direction indicated by the tangent line L2.

[0062] To further understand the above embodiments, refer to Figure 5 the installation schematic diagram of an inner rearview mirror cover shown in the figure. It can be seen that the inner rearview mirror cover can be fixed on the front windshield. The lower side of the inner rearview mirror cover has a grille area, and the grille area is composed of multiple rectangular grid edges; as Figure 6 shown in the three-dimensional schematic diagram of the cover model of an inner rearview mirror cover in the figure.Figure 7 Schematic diagram of the cover model of an interior rearview mirror garnish shown Figure 8 Schematic diagram of another cover model of an interior rearview mirror garnish shown, and Figure 9 Schematic side view of the cover model of an interior rearview mirror garnish shown. It can be seen that the interior rearview mirror garnish has a left-right symmetric structure. Grid regions are provided on the front and left and right sides of the interior rearview mirror garnish, and each grid region is composed of multiple rectangular grid ribs.

[0063] Such as Figure 10 Partial schematic diagram of a grid region shown. The grid region in this figure can be composed of multiple uniformly arranged rectangular grid ribs. In actual implementation, appropriate grid shapes can also be selected according to actual requirements, such as circular grids, polygonal grids, etc.; such as Figure 11 Partial schematic diagram of the cover model of an interior rearview mirror garnish shown. It can be seen that the multiple rectangular grid ribs forming the grid region present a certain inclination angle. Through calibration and adjustment, it can be ensured that the calibrated interior rearview mirror garnish has an anti-seeing-through function while meeting the heat dissipation requirements.

[0064] In actual application, the interior rearview mirror garnish is usually used to hide the interior rearview mirror mounting base fixed on the front windshield and some electrical components. According to the heat dissipation requirements of the electrical components, sometimes a large heat dissipation area is required for the interior rearview mirror garnish, which requires a large grid opening area. However, if the opening area is too large, the driver or the passenger in the co-driver seat can easily see the structure of the internal electrical components through the heat dissipation grid. In order to ensure that the area of the heat dissipation grid is maximally satisfied and the structure of the internal electrical components cannot be seen through at a conventional angle, the anti-seeing-through requirements of the heat dissipation grid of the interior rearview mirror garnish are evaluated according to the driver's habits in this embodiment as follows: ① Along the line of sight direction indicated by the tangent line L1, the internal electrical component structure cannot be seen from the lower heat dissipation grid; ② Along the line of sight direction indicated by the tangent line L2, the internal electrical component structure cannot be seen from the left heat dissipation grid.

[0065] The above grid calibration method for the interior rearview mirror garnish, after the data design is completed, uses the eye point graphics provided in the vehicle design stage to perform grid anti-seeing-through calibration on the interior rearview mirror garnish. By calibrating the grid region of the cover model in the model design stage, it can be ensured that the line of sight cannot see through the internal electrical components hidden through the heat dissipation grid of the interior rearview mirror garnish at a conventional angle, which not only improves the interior perception quality of the vehicle but also helps to optimize costs. After manufacturing the physical object according to the calibrated interior rearview mirror device cover and actually installing it in the vehicle, in the conventional field of view, the driver cannot see the internal electrical components through the grid region of the interior rearview mirror garnish, that is, the grid region has an anti-seeing-through function while meeting the heat dissipation requirements, thereby improving the vehicle perception quality.
