[0043] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0044] like Figure 1 As shown, according to a first aspect of an embodiment of the present application, a vehicle side structure 300 design method is proposed, comprising:

[0045] Step S101: Acquire a vehicle three-dimensional model 100;

[0046] Specifically, during the three-dimensional design stage of the vehicle, the current shape of the vehicle can be understood by obtaining the vehicle three-dimensional model 100, which makes it easier to observe the appearance of the vehicle. Based on the observation of the vehicle three-dimensional model 100, the exposure of the vehicle's bottom layout parts 500 can be judged to provide a reference for the design of the side structure 300. There is no need to trial-produce a prototype during the design stage, which is conducive to reducing design costs.

[0047] It is understandable that the vehicle three-dimensional model 100 refers to the three-dimensional model of the whole vehicle, that is, the vehicle three-dimensional model 100 includes the side structure 300 of the vehicle and the bottom arrangement 500 of the vehicle. The bottom arrangement 500 of the vehicle refers to the parts arranged in the bottom area of ​​the vehicle, including but not limited to the welding edge, battery pack and other parts located at the bottom of the side structure 300.

[0048] Step S102: establishing a simulated observation point 200 according to the vehicle three-dimensional model 100, wherein the simulated observation point 200 is located on the side of the vehicle three-dimensional model 100;

[0049] Specifically, when the vehicle three-dimensional model 100 is obtained, a simulated observation point 200 can be established based on the vehicle three-dimensional model 100. The simulated observation point 200 is located on the side of the vehicle three-dimensional model 100, that is, the simulated observation point 200 and the vehicle three-dimensional model 100 are in the same modeling space and are located in the width direction of the vehicle three-dimensional model 100. The simulated observation point 200 is used to represent the eyes of the observer when observing the side of the actual vehicle in the aforementioned modeling space, so that the position of the simulated observation point 200 relative to the vehicle three-dimensional model 100 can be determined according to the relative position relationship between the eyes of the observer when observing the side of the actual vehicle and the actual vehicle.

[0050] It is understandable that if Figure 2 As shown, in order to evaluate the overall perceived quality of the vehicle, observers usually do not observe the side of the actual vehicle at a position lower than the vehicle chassis. Therefore, when establishing the simulated observation point 200, along the height direction of the vehicle three-dimensional model 100, the height position of the simulated observation point 200 relative to the vehicle three-dimensional model 100 can be higher than the wheels of the vehicle three-dimensional model 100 to avoid the position of the simulated observation point 200 being too low, which affects the authenticity and reliability of the simulated observation.

[0051] Step S103: determining the sight shielding line 400 of the side structure 300 of the vehicle three-dimensional model 100 according to the simulated observation point 200;

[0052] Specifically, after establishing the simulated observation point 200, the line of sight shielding line 400 of the side enclosure structure 300 of the vehicle three-dimensional model 100 can be determined based on the simulated observation point 200. It can be understood that the line of sight shielding line 400 passes through the simulated observation point 200 and is tangent to the contour of the side enclosure structure 300. Therefore, based on the line of sight shielding line 400, when the side simulated observation of the vehicle three-dimensional model 100 is performed at the position of the simulated observation point 200, the line of sight shielding area of ​​the side enclosure structure 300 and the line of sight passing area of ​​the side enclosure structure 300 can be determined, thereby providing a reference for adjusting the contour parameters of the side enclosure structure 300 and adjusting the layout position of the bottom layout component 500.

[0053] It can be understood that the straight line passing through the simulated observation point 200 can be used to represent the line of sight of the observer when observing the side of the actual vehicle. If the straight line passing through the simulated observation point 200 intersects with the side enclosure structure 300, it means that the side enclosure structure 300 can block the line of sight corresponding to the straight line, and the observer can only see the side enclosure structure 300 of the vehicle when observing the side of the actual vehicle from the perspective corresponding to the line of sight; accordingly, if the straight line passing through the simulated observation point 200 is separated from the side enclosure structure 300, it means that the side enclosure structure 300 cannot block the line of sight corresponding to the straight line, and the observer can avoid the side enclosure structure 300 of the vehicle when observing the side of the actual vehicle from the perspective corresponding to the line of sight. Therefore, the tangent point of the line of sight shielding line 400 and the side enclosure structure 300 can reflect the critical position of the line of sight shielding area and the line of sight passing area of ​​the side enclosure structure 300 when observing the side of the vehicle according to the position of the simulated observation point 200.

[0054] It should be noted that for the sake of convenience, Figure 2 Schematically shows the portion of the vehicle three-dimensional model 100 where the side enclosure structure 300 is tangent to the sight shielding line 400 , and hides part of the structure of the vehicle three-dimensional model 100 .

[0055] Step S104 : adjusting the contour parameters of the side enclosure structure 300 and / or the arrangement position parameters of the bottom arrangement component 500 of the vehicle according to the sight shielding line 400 , so as to prevent the bottom arrangement component 500 from passing through the sight shielding line 400 .

[0056] Specifically, when the sight-shielding line 400 is established, the contour parameters of the side enclosure structure 300 can be adjusted according to the sight-shielding line 400 to prevent the bottom arrangement component 500 of the vehicle from passing through the sight-shielding line 400, thereby reducing the possibility of the bottom arrangement component 500 being observed when the vehicle is observed from the side. Further, the whole vehicle can be processed and produced based on the adjusted contour parameters of the side enclosure structure 300, which can improve the shielding effect of the side enclosure structure 300 on the bottom arrangement component 500 and enhance the aesthetics of the vehicle.

[0057] At the same time, the layout position parameters of the bottom arrangement component 500 can also be adjusted according to the line of sight shielding 400, so that the bottom arrangement component 500 avoids the line of sight shielding 400, and avoids the bottom arrangement component 500 passing through the line of sight shielding 400, thereby reducing the possibility of the bottom arrangement component 500 being observed when the vehicle is observed from the side, and then the whole vehicle is processed and produced based on the adjusted layout position parameters of the bottom arrangement component 500, which can improve the shielding effect of the side structure 300 on the bottom arrangement component 500 and enhance the aesthetics of the vehicle.

[0058] It is understandable that the contour parameters of the side enclosure structure 300 and the layout position parameters of the bottom layout component 500 can also be adjusted simultaneously to further improve the flexibility in designing the side enclosure structure 300, facilitate expanding the design scheme of the side enclosure structure 300, and help improve the design feasibility of the side enclosure structure 300.

[0059] For example, Figure 3 As shown, Figure 3 The bottom arrangement component 500 shown in the figure is a welding edge arranged at the bottom of the side enclosure structure 300. By adjusting the contour parameters of the side enclosure structure 300 and / or the arrangement position parameters of the bottom arrangement component 500 of the vehicle, the welding edge avoids the sight shielding line 400, thereby reducing the possibility of the welding edge being observed when observing the vehicle from the side.

[0060] It should be noted that the specific adjustment method for adjusting the contour parameters of the side enclosure structure 300 may be to directly adjust the contour parameters of the current side enclosure structure 300 so as to change the contour shape of the side enclosure structure 300 without adding or deleting parts of the side enclosure structure 300; or to change the contour shape of the side enclosure structure 300 by adding exterior trim to the current side enclosure structure 300, thereby adjusting the contour parameters of the side enclosure structure 300. When adjusting the layout position parameters of the bottom arrangement component 500, it should be ensured that the adjusted bottom arrangement component 500 is still located in the bottom area of ​​the vehicle.

[0061] In summary, the vehicle side enclosure structure 300 design method provided in the embodiment of the present application obtains the vehicle three-dimensional model 100; establishes the simulation observation point 200 according to the vehicle three-dimensional model 100; determines the sight shielding line 400 of the side enclosure structure 300 of the vehicle three-dimensional model 100 according to the simulation observation point 200; adjusts the contour parameters of the side enclosure structure 300 and / or the arrangement position parameters of the bottom arrangement part 500 of the vehicle according to the sight shielding line 400 to avoid the bottom arrangement part 500 passing through the sight shielding line 400, so that the side observation simulation of the side enclosure structure 300 can be performed based on the current shape of the vehicle during the design stage. , determining the shielding effect of the current side enclosure structure 300 on the bottom arrangement part 500 of the vehicle, so as to judge whether there is a possibility of the bottom arrangement part 500 being observed, thereby preventing the bottom arrangement part 500 from passing through the line of sight shielding line 400 by adjusting the contour parameters of the side enclosure structure 300 and / or the arrangement position parameters of the bottom arrangement part 500, and further reducing the possibility of the bottom arrangement part 500 being exposed from the side enclosure structure 300 when the vehicle is observed from the side, thereby providing a reliable guarantee for improving the overall image of the vehicle, improving the overall perceived quality of the vehicle, and helping to improve the user experience of the vehicle.

[0062] In some examples, the step of establishing the simulated observation point 200 according to the vehicle three-dimensional model 100 includes:

[0063] According to the vehicle three-dimensional model 100 , a reference reference plane 600 is established, and the reference reference plane 600 is tangent to the static radius surface 700 of each wheel of the vehicle three-dimensional model 100 ;

[0064] According to the vehicle three-dimensional model 100 and the reference reference plane 600, a simulated observation point 200 is established. The simulated observation point 200 forms a first preset distance W with the vehicle three-dimensional model 100 along the width direction of the vehicle three-dimensional model 100, and a second preset distance H1 is formed between the simulated observation point 200 and the reference reference plane 600.

[0065] Specifically, Figure 4 As shown, in the process of establishing the simulated observation point 200 according to the vehicle three-dimensional model 100, a reference reference plane 600 can be established according to the vehicle three-dimensional model 100, and the reference reference plane 600 is tangent to the static radius surface 700 of each wheel of the vehicle three-dimensional model 100, so that the reference reference plane 600 can be used to more realistically represent the ground where the vehicle three-dimensional model 100 is located in the modeling space, and then the simulated observation point 200 is established according to the vehicle three-dimensional model 100 and the reference reference plane 600, wherein the simulated observation point 200 A first preset distance W is formed with the vehicle three-dimensional model 100 along the width direction of the vehicle three-dimensional model 100, and a second preset distance H1 is formed between the side view point 200 and the reference datum plane 600. Therefore, based on the aforementioned method of establishing the simulated observation point 200, the position of the simulated observation point 200 can be made closer to the eye position of the observer when observing the side of the actual vehicle, so as to establish the position of the sight line shielding line 400 closer to reality, provide a more reliable reference for the design of the side structure 300, and provide further guarantee for the improvement of the aesthetics of the entire vehicle.

[0066] It can be understood that the static radius of the wheel refers to the vertical distance from the axis of the wheel axle to the ground under the action of a static vertical load. Accordingly, the static radius surface 700 of the wheel, that is, the straight line parallel to the axis of the wheel axle, is a curved surface obtained by rotating relative to the axis of the wheel axle with the axis of the wheel axle as the center of rotation and the static radius as the radius of rotation. Along the height direction of the vehicle three-dimensional model 100, the reference reference plane 600 is lower than the axis of the wheel axle of each wheel.

[0067] It should be noted that for the sake of convenience, Figure 4 FIG. 5 schematically shows a portion of the static radius surface 700 that is tangent to the reference datum plane 600 .

[0068] In some examples, the first preset distance W is greater than or equal to 1.5 m and less than or equal to 2.5 m; the second preset distance H1 is greater than or equal to 1.4 m and less than or equal to 1.7 m.

[0069] Specifically, by setting the first preset distance W to be greater than or equal to 1.5m and less than or equal to 2.5m, and setting the second preset distance H1 to be greater than or equal to 1.4m and less than or equal to 1.7m, the simulated observation point 200 can be made closer to the lateral distance and eye height of the observer's eyes relative to the actual vehicle when observing the actual vehicle, thereby improving the authenticity of the shielding line, providing a more reliable reference for the design of the side structure 300, and providing further guarantee for the improvement of the aesthetics of the entire vehicle.

[0070] In some feasible examples, the first preset distance W is equal to 2 m; and the second preset distance H1 is equal to 1.5 m.

[0071] In some examples, the step of determining the sight shielding line 400 of the side structure 300 of the vehicle three-dimensional model 100 according to the simulated observation point 200 includes:

[0072] Taking the simulated observation point 200 as the starting point, a sight line simulation ray is established, and a sight line simulation angle is formed between the sight line simulation ray and the reference datum plane 600;

[0073] Adjusting the sight line simulation angle so that the sight line simulation ray is tangent to the bottom contour 800 of the side surrounding structure 300;

[0074] When the line of sight simulation ray is tangent to the bottom contour 800 of the side surrounding structure 300 , the line of sight simulation line of sight is determined to be the line of sight shielding line 400 .

[0075] Specifically, in the process of determining the line of sight shielding line 400 of the side enclosure structure 300 of the vehicle three-dimensional model 100 according to the simulated observation point 200, the simulated observation point 200 can be used as the starting point to establish a simulation ray, and the line of sight simulation ray is used to simulate the line of sight when the observer's eyes are located at the simulated observation point 200. A line of sight simulation angle is formed between the line of sight simulation ray and the reference datum plane 600, so that the line of sight simulation angle can be adjusted to simulate the line of sight of the observer at different line of sight angles. When the line of sight simulation ray is tangent to the bottom contour 800 of the side enclosure structure 300, the line of sight simulation ray at the current line of sight simulation angle is determined to be the line of sight shielding line 400, and then based on the line of sight shielding line 400, the shielding range of the side enclosure structure 300 to the bottom area of ​​the vehicle can be determined more specifically, which further facilitates the design of the side enclosure structure 300 and improves the design efficiency of the side enclosure structure 300.

[0076] In some examples, the vehicle side structure 300 design method further includes:

[0077] According to the reference datum plane 600, a minimum ground clearance reference plane 900 is established;

[0078] According to the minimum ground clearance reference plane 900 , the contour parameters of the side enclosure structure 300 and / or the arrangement position parameters of the bottom arrangement component 500 are adjusted so that both the side enclosure structure 300 and the bottom arrangement component 500 are higher than the minimum ground clearance reference plane 900 .

[0079] Specifically, Figure 4 As shown, a minimum ground clearance reference plane 900 can be further established based on the reference datum plane 600, and the contour parameters of the side enclosure structure 300 and / or the layout position parameters of the bottom arrangement component 500 can be further adjusted based on the minimum ground clearance reference plane 900, so that both the side enclosure structure 300 and the bottom arrangement component 500 are higher than the minimum ground clearance reference plane 900, thereby avoiding the side enclosure structure 300 or the bottom arrangement component 500 from failing to meet the vehicle's passability requirements, thereby ensuring the vehicle's passability performance after design.

[0080] It should be noted that, along the height direction of the vehicle three-dimensional model 100, the minimum ground clearance reference plane 900 is higher than the reference reference plane 600; and, the layout position parameters of the bottom arrangement component 500 obtained after adjustment should simultaneously meet the requirements of avoiding the bottom arrangement component 500 from passing through the line of sight shielding line 400, and the requirement that the bottom arrangement component 500 is higher than the minimum ground clearance reference plane 900.

[0081] It can be understood that if the contour parameters of the side enclosure structure 300 and the layout position parameters of the bottom layout component 500 are able to meet the requirement that both the side enclosure structure 300 and the bottom layout component 500 are higher than the minimum ground clearance reference plane 900 before being adjusted according to the minimum ground clearance reference plane 900, then it is no longer necessary to make adjustments according to the minimum ground clearance reference plane 900.

[0082] In some examples, the step of establishing the minimum ground clearance reference plane 900 according to the reference datum plane 600 includes:

[0083] Get the minimum ground clearance of the vehicle;

[0084] According to the minimum ground clearance and the reference datum plane 600 , a minimum ground reference plane 900 is established. The minimum ground reference plane 900 is parallel to the reference datum plane 600 , and a spacing distance W between the reference datum plane 600 and the minimum ground reference plane 900 is equal to the minimum ground clearance.

[0085] Specifically, Figure 4As shown, in the process of establishing the minimum ground clearance reference plane 900 according to the reference reference plane 600, the minimum ground clearance of the vehicle can be obtained, so that the minimum ground clearance reference plane 900 is established according to the minimum ground clearance and the reference reference plane 600, the minimum ground clearance reference plane 900 is parallel to the reference reference plane 600, and the spacing distance W between the reference reference plane 600 and the minimum ground clearance reference plane 900 is equal to the minimum ground clearance, so that the adjusted side enclosure structure 300 and the bottom arrangement component 500 can meet the minimum ground clearance requirement of the vehicle, and, combined with the aforementioned design method, after the design is completed, while ensuring the vehicle's passability, the possibility of exposure of the bottom arrangement component 500 can be reduced, thereby improving the aesthetics of the entire vehicle.

[0086] According to a second aspect of an embodiment of the present application, a storage medium is proposed, the storage medium includes a stored program, wherein when the program is running, the device where the storage medium is located is controlled to execute the design method proposed in any one of the above-mentioned first aspects.

[0087] Since the storage medium provided in the embodiment of the present application is used to implement the design method proposed in any one of the first aspects above, it has all the beneficial effects of the design method proposed in any one of the first aspects above, which will not be repeated here.

[0088] like Figure 5 As shown, according to the third aspect of an embodiment of the present application, an electronic device 500 is proposed, and the electronic device 500 includes at least one processor 501 and at least one memory 502 connected to the processor 501, wherein the processor 501 is used to call program instructions in the memory 502 to execute a design method proposed in any one of the first aspects above.

[0089] Since the electronic device 500 provided in the embodiment of the present application is used to implement the design method proposed in any one of the first aspects above, it has all the beneficial effects of the design method proposed in any one of the first aspects above, which will not be repeated here.

[0090] According to a fourth aspect of an embodiment of the present application, a side enclosure structure is proposed, and contour parameters of the side enclosure structure are determined according to a design method as proposed in any one of the first aspects above.

[0091] The side enclosure structure provided in the embodiment of the present application, when serving as a part of a vehicle, can enhance the shielding effect of the vehicle's bottom arrangement 500. When people near the vehicle observe the vehicle from the side, the possibility of the bottom arrangement 500 being observed can be reduced, thereby improving the aesthetics of the entire vehicle, improving the perceived quality of the entire vehicle, and helping to enhance the user experience of the vehicle.

[0092] According to a fifth aspect of an embodiment of the present application, a vehicle is proposed, comprising: a side enclosure structure as proposed in the fourth aspect above.

[0093] Since the vehicle provided in the embodiment of the present application includes the side enclosure structure proposed in the fourth aspect above, it has all the beneficial effects of the side enclosure structure proposed in the fourth aspect above, which will not be described in detail here.
