[0045] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0047] In a first aspect, an embodiment of the present application provides a method for designing the main section of a rear wheel cover.

[0048] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the rear wheel cover main section design method of the present application. Figure 1 As shown, the design method of the main section of the rear wheel cover includes:

[0049] Step S10, obtaining design parameters corresponding to the main section of the rear wheel cover to be checked, wherein the design parameters include the distance L between the rear row R point and the rear wheel center, the rear tire radius L1, the distance L2 between the rear wheel eyebrow outer contour point and the rear tire, and the minimum side perimeter width L3;

[0050] In this embodiment, the main section of the rear wheel housing to be checked is obtained by drawing, for example:

[0051] Based on the design input, the reference plane is drawn as the plane passing through the rear wheel center and perpendicular to the rear door and side panel seam or rear wheel eyebrow, and the rear door and side panel structure are fitted to the reference point of the rear wheel eyebrow outer contour, and then the rear fender, rear door interior panel, C-pillar lower guard plate and other details are added. The minimum clearance between the rear wheel cover fender and the rear tire is required to be ≥10mm, and then the main section of the wheel cover is completed and used as the main section of the rear wheel cover to be checked. Among them, the design input includes the rear R point position, rear tire specifications, rear door seam form, etc.

[0052] The distance L between the rear R point and the rear wheel center is related to the rear R point and the vehicle wheelbase. After the rear R point and the vehicle wheelbase are set, L can be determined. Figure 2 , Figure 2 is a geometric diagram related to determining L. Figure 2 As shown, L can be calculated according to the Pythagorean theorem. Among them, H is the longitudinal distance between the rear R point and the rear wheel center, and A is the lateral distance between the rear R point and the rear wheel center.

[0053] In this embodiment, L can be determined by the execution subject of this embodiment based on the rear R point and the wheelbase of the whole vehicle, thereby obtaining L; of course, L can also be determined by other execution subjects based on the rear R point and the wheelbase of the whole vehicle, and the execution subject of this embodiment obtains L from the other execution subjects.

[0054] The rear tire radius L1 is related to the rear tire specifications. Once the rear tire specifications are selected, L1 can be determined. Figure 3 , Figure 3 is a geometric diagram related to determining L1. Figure 3 As shown, W is the tire section width, D is the tire diameter, B is the rim diameter, and C is the tire sidewall height, then:

[0055] L1=D / 2=(B+2C) / 2

[0056] For example, the tire specification is 265 / 45, R21, 265 represents the tire section width W, 45 (%) represents the aspect ratio = tire sidewall height C / tire section width W, R21 represents the rim diameter B (this unit is inches, which needs to be converted to mm when calculating), then:

[0057] L1=D / 2=(21*25.4+265*0.45*2) / 2

[0058] In this embodiment, L1 can be determined by the execution subject of this embodiment based on the rear tire specifications, thereby obtaining L1; of course, L1 can also be determined by other execution subjects based on the rear tire specifications, and the execution subject of this embodiment obtains L1 from the other execution subject end.

[0059] The minimum width L3 of the side panel is related to the size of the side panel C-pillar cavity and the seam between the rear door and the side panel. Once the size of the side panel C-pillar cavity and the seam between the rear door and the side panel are set, L3 can be determined. Figure 4 , Figure 4 It is a geometric diagram related to determining L3. Figure 4 The geometric relationships shown are:

[0060] L3=a1+h*tanθ+a2+a3+a4

[0061] Among them, a1 is the distance between the rear wheel arch boundary and the rear wheel cover outer panel; a2 is the cavity size between the C-pillar reinforcement plate and the rear wheel cover outer panel; a3 is the glue coating gap between the side panel outer panel and the C-pillar reinforcement plate; a4 is the distance between the side panel stop boundary and the first side panel flange; h is the stamping depth of the side panel outer panel; θ is the draft angle of the rear wheel cover outer panel.

[0062] It should be noted that after the size of the side C-pillar cavity and the seam between the rear door and the side can be set, the distance between the rear wheel arch boundary and the rear wheel cover outer panel a1, the cavity size between the C-pillar reinforcement plate and the rear wheel cover outer panel a2, the glue gap between the side outer panel and the C-pillar reinforcement plate a3, the distance between the side stop boundary and the first flange of the side a4, the stamping depth h of the side outer panel, and the draft angle θ of the rear wheel cover outer panel can be determined. When determining these values, the range of each value needs to be further considered.

[0063] In this embodiment, L3 can be determined by the execution body of this embodiment based on the size of the side panel C-pillar cavity and the form of the seam between the rear door and the side panel, thereby obtaining L3; of course, L3 can also be determined by other execution bodies based on the size of the side panel C-pillar cavity and the form of the seam between the rear door and the side panel, and the execution body of this embodiment obtains L3 from the other execution body ends.

[0064] The design input also includes the distance L2 between the outer contour point of the rear wheel arch and the rear tire. When manually drawing the main section of the rear wheel cover, this value can be determined based on experience.

[0065] Step S20, based on the design parameters, detecting whether the main section of the rear wheel cover to be checked meets the requirements of styling and convenience of getting on and off the vehicle;

[0066] In this embodiment, the numerical form of the design parameters that meet the styling requirements and the convenience requirements of getting on and off the vehicle is preset, and it is determined whether the current design parameters meet the preset numerical requirements. If the current design parameters meet the preset numerical requirements, it is determined that the styling requirements and the convenience requirements of getting on and off the vehicle are met; if the current design parameters do not meet the preset numerical requirements, it is determined that the styling requirements and the convenience requirements of getting on and off the vehicle are not met.

[0067] Step S30: If the main section of the rear wheel arch to be checked meets the styling requirements and the convenience requirements for getting on and off the vehicle, it is determined that the main section of the rear wheel arch to be checked is valid.

[0068] In this embodiment, if it is determined based on the design parameters corresponding to the main section of the rear wheel cover to be checked that the main section of the rear wheel cover to be checked meets the styling requirements and the convenience requirements of getting on and off the vehicle, then the main section of the rear wheel cover to be checked is determined to be valid.

[0069] In this embodiment, the design parameters corresponding to the main section of the rear wheel cover to be checked are obtained, and the design parameters include the distance L between the rear row R point and the rear wheel center, the radius L1 of the rear tire, the distance L2 between the outer contour point of the rear wheel eyebrow and the rear tire, and the minimum width L3 of the side perimeter; based on the design parameters, it is detected whether the main section of the rear wheel cover to be checked meets the styling requirements and the convenience requirements of getting on and off the vehicle; if the main section of the rear wheel cover to be checked meets the styling requirements and the convenience requirements of getting on and off the vehicle, it is determined that the main section of the rear wheel cover to be checked is valid. Through this embodiment, the styling requirements and the convenience requirements of getting on and off the vehicle can be automatically considered synchronously based on the design parameters, thereby ensuring that the main section of the rear wheel cover determined to be valid can take into account both the styling requirements and the convenience requirements of getting on and off the vehicle.

[0070] Furthermore, in one embodiment, step S20 includes:

[0071] Step S201, obtaining the distance L4 between the rear row point R and the rear end of the door opening according to L, L1, L2 and L3;

[0072] In this embodiment, refer to Figure 5 , Figure 5 It is a schematic diagram of the geometric relationship between design parameters. Figure 5 According to the geometric relationship shown in the figure, after determining the distance L between the rear point R and the rear wheel center, the rear tire radius L1, the distance L2 between the rear wheel eyebrow outer contour point and the rear tire, and the minimum width L3 of the side wall, the distance L4 between the rear point R and the rear end of the door opening can be determined.

[0073] Furthermore, in one embodiment, step S201 includes:

[0074] Substitute L, L1, L2 and L3 into the calculation formula of the distance between the rear row point R and the rear end of the door opening to obtain the distance L4 between the rear row point R and the rear end of the door opening. The calculation formula of the distance between the rear row point R and the rear end of the door opening is:

[0075] L4=L-L1-L2-L3.

[0076] Step S202, determining whether L4 is greater than or equal to a preset threshold;

[0077] In this embodiment, the preset threshold is determined by comparing a large number of related products and subjective and objective research. In an optional embodiment, the preset threshold can be set to 0, and of course can also be set to 0.1 or other values, and the unit is mm.

[0078] Step S203, if L4 is greater than or equal to the preset threshold, it is determined that the main section of the rear wheel housing to be checked meets the styling requirements and the convenience requirements for getting on and off the vehicle;

[0079] Step S204, if L4 is less than a preset threshold, it is determined that the main section of the rear wheel arch to be checked does not meet the styling requirements and the convenience requirements for getting on and off the vehicle.

[0080] In this embodiment, if L4 is greater than or equal to the preset threshold, it is determined that the main cross-section of the rear wheel arch to be checked meets the styling requirements and the convenience requirements of getting on and off the vehicle; if L4 is less than the preset threshold, it may cause the buttocks of the rear passengers to easily scratch the door opening when getting on and off the vehicle, then it is determined that the main cross-section of the rear wheel arch to be checked does not meet the styling requirements and the convenience requirements of getting on and off the vehicle.

[0081] Furthermore, in one embodiment, after step S20, the method further includes:

[0082] If the main section of the rear wheel cover to be checked does not meet the requirements of styling and convenience of getting on and off the vehicle, the design parameters are adjusted;

[0083] The main section of the rear wheel cover to be checked is adjusted based on the adjusted design parameters to obtain a new main section of the rear wheel cover to be checked;

[0084] The new main section of the rear wheel cover to be checked is used as the main section of the rear wheel cover to be checked, and the step of obtaining the design parameters corresponding to the main section of the rear wheel cover to be checked is returned.

[0085] In the present embodiment, if the main section of the rear wheel cover to be checked does not meet the styling requirements and the requirements of the convenience of getting on and off the vehicle, the design parameters are adjusted; then, the main section of the rear wheel cover to be checked is adjusted based on the adjusted design parameters to obtain a new main section of the rear wheel cover to be checked; finally, the new main section of the rear wheel cover to be checked is used as the main section of the rear wheel cover to be checked, and the process returns to the step of obtaining the design parameters corresponding to the main section of the rear wheel cover to be checked.

[0086] That is, in this embodiment:

[0087] Determine whether the rear wheel cover main section v1 meets the styling requirements and the convenience requirements for getting on and off the vehicle;

[0088] When the rear wheel cover main section v1 does not meet the requirements of styling and convenience of getting on and off the vehicle, it is modified to obtain the rear wheel cover main section v2;

[0089] Determine whether the rear wheel cover main section v2 meets the styling requirements and the convenience requirements for getting on and off the vehicle;

[0090] When the rear wheel cover main section v2 does not meet the requirements of styling and the convenience of getting on and off the vehicle, it is modified to obtain the rear wheel cover main section v3;

[0091] Determine whether the rear wheel arch main section v3 meets the styling requirements and the convenience requirements of getting on and off the vehicle, and so on.

[0092] Among them, v1, v2, and v3 represent different versions. When the main cross-section of the rear wheel cover of any version meets the styling requirements and the convenience requirements of getting on and off the vehicle, the main cross-section of the rear wheel cover of this version is determined to be valid.

[0093] Furthermore, in one embodiment, the step of adjusting the design parameters includes:

[0094] Reduce L2 included in the design parameters by a preset value.

[0095] In this embodiment, if the main cross-section of the rear wheel arch to be checked does not meet the styling requirements and the convenience requirements of getting on and off the vehicle, that is, L4 is less than the preset threshold, then L4 needs to be increased. Since L4=L-L1-L2-L3, in order to achieve the purpose of increasing L4, L2 included in the design parameters is reduced by a preset value.

[0096] The preset value is a fixed value set in advance, and may also be determined based on a current value setting operation.

[0103] According to L, L1, L2 and L3, the distance L4 between the rear point R and the rear end of the door opening is obtained;

[0104] Determine whether L4 is greater than or equal to a preset threshold;

[0105] If L4 is greater than or equal to the preset threshold, it is determined that the main section of the rear wheel cover to be checked meets the styling requirements and the convenience requirements for getting on and off the vehicle;

[0106] If L4 is less than a preset threshold, it is determined that the main section of the rear wheel arch to be checked does not meet the styling requirements and the convenience requirements for getting on and off the vehicle.

[0107] Furthermore, in one embodiment, the detection module 20 is specifically used for:

[0108] Substitute L, L1, L2 and L3 into the calculation formula of the distance between the rear row point R and the rear end of the door opening to obtain the distance L4 between the rear row point R and the rear end of the door opening. The calculation formula of the distance between the rear row point R and the rear end of the door opening is:

[0109] L4=L-L1-L2-L3.

[0110] Furthermore, in one embodiment, the rear wheel housing main section design device further comprises:

[0114] Furthermore, in one embodiment, the parameter adjustment module is used to:
