DETAILED DESCRIPTION

[0020] The commercial vehicle mask design method provided by this application is to solve the problem that in the existing commercial vehicle mask design process, a large number of repeated design parameter comparisons are required to complete the design by comparing the matching and whether the design requirements are met, resulting in long design time and low design accuracy. The commercial vehicle mask design method of this application realizes the automatic generation of the target mask structure. The target mask structure can be quickly generated, and only manual adjustments are required later to obtain the required mask structure data, thereby improving design efficiency.

[0021] The specific process of the commercial vehicle mask design method will be described in detail below. For the purpose of illustration rather than limitation, specific details such as specific system structures and technologies are proposed to facilitate a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details.

[0022] The phrases such as "one embodiment" or "some embodiments" described in the present application mean that the specific features, structures or characteristics described in the embodiment are included in one or more embodiments of the present application. Therefore, the phrases such as "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments" etc. that appear in different places in the present application do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 and Figure 2 The flowchart of a commercial vehicle mask design method in a specific embodiment is shown, and the method includes: S101: configuring the mask body.

[0025] The design method of the mask body specifically includes the following steps: Input the CAS surface data of the mask body into the design module. The design module can be implemented using Catia software or other related software.

[0026] In some embodiments, the user imports the CAS (Class-A Surface) surface data of the mask body into the design software module through the design operation interface. The mask body design data may include precise geometric information of the mask appearance shape.

[0027] In the design module, define the material type of the mask body. Users can select the material type of the mask body from the preset material library, such as UP+GF composite material (unsaturated polyester + glass fiber), metal or PP+LGF composite material (polypropylene + long glass fiber), etc.

[0028] Specifically, the material can be selected according to the use environment and performance requirements of the commercial vehicle to ensure that the performance indicators of the mask such as strength, durability, and corrosion resistance meet the requirements.

[0029] The design module retrieves the boss column of preset size from the database according to the input CAS surface data, and configures the boss column to the mask body. Here, the boss column, that is, the BOSS column size, can be retrieved from the database. The boss column is a standard part pre-designed and stored in the database. The selected boss column is accurately placed on the corresponding position of the mask body through the geometric positioning algorithm. This can reduce the time for users to manually find and place the connection parts, speeding up the design process.

[0030] In some embodiments, the material thickness is matched according to the defined material type. For example, if UP+GF material is selected, the system may automatically match the material thickness to 4.0 mm. In this way, it can ensure that the material thickness matches the material properties, avoiding the problem of insufficient strength or material waste caused by improper material thickness.

[0031] Based on the information of the mask body, material type and thickness obtained in the above way, the design software intuitively displays the mask body model with the boss column configured and the material thickness determined through a 3D visualization interface. Users can view the details of the model through operations such as rotation, scaling, and sectioning, so as to find and correct design defects in a timely manner.

[0032] S102: Design a mask grille on the mask body.

[0033] In some embodiments, the user first inputs the CAS surface data of the mask grille into the design module to determine the shape of the grille, then selects the surface treatment method of the grille, and determines the material thickness parameters of the mask grille and the installation method of the mask grille on the mask body according to the selected surface treatment method.

[0034] The material thickness parameter of the mask grille can be set to PP-23 material, with a thickness of 3.5mm to 4mm, and a snap-on installation method is used. Finally, the designed grille data is fed back to the mask body data.

[0035] In one embodiment of the present invention, Figure 3 As shown, based on step S102, a possible embodiment will be given below to illustrate its specific implementation scheme in a non-limiting manner.

[0036] S1021: The user inputs the CAS surface data of the mask grille into the design module. The user can determine the mask grille shape based on the mask grille shape pre-stored in the database or the shape of the mask grille currently designed.

[0037] S1022: Surface treatment of mask grille.

[0038] Specifically, choose from preset surface treatments, such as leather grain, electroplating, etc. Different surface treatments will affect the subsequent selection of materials and installation methods.

[0039] S1023: Determine the material, thickness and installation method of the mask grille on the mask body.

[0040] For example, a leather grain surface treatment may be selected, the material selected may be PP-23, the material thickness may be set to 3.5 mm, and the installation method may be a snap-on installation.

[0041] For other surface treatment methods, the system determines the appropriate material, material thickness and installation method based on the preset correspondence.

[0042] S1024: Configure the designed mask grille into the mask body design data.

[0043] This embodiment reduces design time and workload by matching materials, material thickness and installation methods, eliminating the need for manual search and calculation by the user. For design process modifications, the input CAS surface data or material type can be changed, and the system can quickly regenerate the corresponding design, making it convenient for users to quickly iterate and optimize.

[0044] S103: Design the mask hinge, mask support rod and mask lock, and configure them on the mask body.

[0045] In some embodiments, the user can configure the X, Y, and Z coordinates of the mask hinge mounting interface. The system can locate the mask body and select the mounting position according to the length of the mask body. The mounting position of this embodiment can be set at 20% or 80% of the total length of the body, and then call the BOSS column interface from the database for splicing.

[0046] The mask support rod design of this embodiment is based on the user inputting the X, Y, and Z coordinates of the support rod installation interface, and automatically positioning it on the mask body. According to the actual needs of the vehicle, a common support rod or a gas spring type support rod is configured and configured on the mask body.

[0047] In some specific embodiments, the mask lock is designed based on the coordinates of the mask lock installation interface input by the user for positioning. After positioning, the mask lock is selected from the database according to the design requirements and configured to the corresponding position of the mask body.

[0048] In this way, through coordinate positioning and automatic matching, it is ensured that components such as hinges, struts and locks can be accurately installed on the mask body, thereby improving assembly accuracy.

[0049] Taking the mask grille hinge design as an example, we first obtain the overall design information of the mask grille, which includes size, shape, function, material, and the installation position and type of the hinge.

[0050] Use the design module to create a preliminary 3D model of the mask grille. Define the coordinate system in the X, Y, and Z directions in the preliminary 3D model, and ensure that the origin, direction, and unit of the coordinate system are consistent with the design requirements.

[0051] Calculate the X coordinate of the installation position based on the total length of the mask grille. For example, choose to install the hinge at 20% or 80% of the total length of the body. Determine the Y and Z coordinates to ensure that the installation interface of the hinge maintains an appropriate distance and angle with the surface or edge of the mask grille. Mark the installation position coordinates of the hinge in the design module.

[0052] As an implementation of this embodiment, the design method of the mask grille can first select a preset boss column interface and access a database containing boss column interface data. According to the installation information of the hinge and the material, thickness and other parameters of the mask grille, the boss column interface is selected from the database. The boss column interface is matched with the material and thickness of the mask grille and the installation method of the hinge.

[0053] According to the determined installation position coordinates, locate the boss column interface to the corresponding position of the mask grille, and adjust the gap and angle between the boss column interface and the mask grille.

[0054] Analyzing the installation position of the mask grille and hinges, setting the installation position and mechanical strength of the mask grille and hinges, etc., can ensure sufficient strength and stability under the expected conditions of use.

[0055] Finally, the designed mask grille can be checked to verify whether it meets the requirements. If it does not meet the design requirements, the parameters can be adjusted on the operation interface to meet the design requirements. Through the automatic installation position calculation and boss column interface selection, the user's operation is convenient and the design efficiency is improved. The installation position is automatically matched according to the length of the mask grille to improve the rationality and stability of the installation.

[0056] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
