[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0047] The following is combined with Figures 1-2 This invention describes a universal design method for injection-molded instrument panel tube beams of different widths. The universal design method for injection-molded instrument panel tube beams of different widths according to embodiments of the present invention includes the following steps:

[0048] Step S1: Standardize the driver's side layout for various under-development models with different cab widths.

[0049] Step S2: Design the main instrument panel beam 1 for the driver's side of various models under development.

[0050] Step S3: Design the layout of the passenger side of each model under development according to the configuration requirements of each model under development.

[0051] Step S4: Design the instrument panel sub-beam 2 for each model under development based on the layout of the passenger side of each model under development.

[0052] Step S5: Connect the main instrument panel beam 1 and the secondary instrument panel beam 2 to form the instrument panel beam for each model under development.

[0053] For example, such as Figure 1 As shown, the cab width of the vehicle under development has various dimensions, such as 2080mm or 1880mm. When designing the dashboard of the vehicle under development, the structure of the dashboard on the driver's side is designed first, and then the structure of the dashboard on the passenger side is designed.

[0054] First, the driver's side of various models under development with different cab widths will be uniformly arranged to ensure that the internal layout of the driver's side remains consistent in cabs of different widths, thereby achieving greater versatility and interchangeability.

[0055] Next, a general-purpose instrument panel main beam 1 for the driver's side is designed to be applicable to various models under development. By designing a general-purpose instrument panel main beam 1, the need to design and manufacture a dedicated instrument panel main beam 1 for each model is reduced, thereby reducing production costs and the complexity of inventory management.

[0056] Then, based on the configuration requirements of each vehicle under development, the layout of the passenger side of each vehicle under development is designed to ensure that the interior layout of the passenger side can meet the specific functional and spatial requirements of different vehicles.

[0057] Subsequently, based on the layout of the passenger side of each model under development, the instrument panel sub-beam 2 of each model under development was designed to match the layout of the passenger side and adapt to cabs of different widths.

[0058] Finally, the main instrument panel beam 1 and the secondary instrument panel beam 2 are connected to form the instrument panel beam for each model under development.

[0059] In related technologies, each different width of the vehicle body requires a separately designed and manufactured dedicated dashboard tube beam. Each vehicle model requires a separate mold and a separate production process, which not only increases initial development costs but also raises subsequent production costs.

[0060] The universal design method for injection-molded instrument panel tube beams of different widths in this invention achieves universal design of instrument panel tube beams through the above steps, eliminating the need to design and manufacture dedicated instrument panel tube beams for different vehicle body widths, thereby significantly reducing manufacturing costs.

[0061] The universal design method for injection-molded instrument panel tube beams of different widths in this embodiment of the invention designs the main instrument panel tube beam 1 as universal, which simplifies the production and assembly process and thus improves production efficiency. Moreover, the instrument panel auxiliary tube beam 2 is smaller in size, and the required mold size is also relatively smaller. This not only reduces the investment cost of molds, but also shortens the development cycle and further improves development efficiency.

[0062] Furthermore, the universal design method for injection-molded instrument panel tube beams of different widths in this embodiment of the invention allows for modular design of the main instrument panel tube beam 1, enabling instrument panel tube beams of different models to share more standardized components, thereby further improving the flexibility of design and production.

[0063] Therefore, the universal design method for injection-molded instrument panel tube beams of different widths in this invention has the advantages of high versatility and low cost.

[0064] In some embodiments, step S1 includes: collecting cab configuration information of various models under development; selecting environmental components to be installed on the driver's side and arranging them uniformly.

[0065] For example, step S1 includes: First, collecting cab configuration information from various models under development, covering key parameters such as cab width, internal layout, and mounting point locations for different models. Next, based on the collected information, selecting environmental components uniformly installed on the driver's side, such as the steering system, brake pedal, clutch pedal, air conditioning system, washer assembly, and relay box assembly, and arranging them uniformly. This uniform arrangement ensures that the internal layout of the driver's side remains consistent across cabs of different widths, thereby achieving greater versatility and interchangeability. This process not only simplifies the design and production process but also lays the foundation for subsequent instrument panel tube beam design and manufacturing.

[0066] In some embodiments, step S2 includes: designing the dimensions of the instrument panel main beam 1; determining the structure of the instrument panel main beam 1 on the driver's side; and planning the hardpoint arrangement of the instrument panel main beam 1 on the driver's side.

[0067] For example, firstly, design the dimensions of the main instrument panel beam 1 to ensure it can accommodate cabs of different widths. For instance, if the cab width is 2080mm or 1880mm, design the width of the main instrument panel beam 1 to be 1500mm.

[0068] Next, the structure of the main beam 1 of the instrument panel on the driver's side is determined, including its shape, thickness and the layout of the reinforcing ribs, to ensure its strength and rigidity under various working conditions.

[0069] Finally, the hardpoint layout of the main beam 1 of the instrument panel on the driver's side is planned, that is, the positions of each mounting point and fixing point on the main beam 1 of the instrument panel are determined to ensure that these points can be accurately and firmly connected to the environmental components.

[0070] The present invention implements a universal design method for injection-molded instrument panel tube beams of different widths. Through these detailed steps, a universal, structurally reasonable, and easy-to-install instrument panel main tube beam 1 is designed, laying a solid foundation for realizing universal design for different vehicle models.

[0071] In some embodiments, determining the structure of the main instrument panel beam 1 on the driver's side includes: designing an installation structure for the environmental components installed on the driver's side; and providing a uniform male connector 11 at one end of the main instrument panel beam 1 for connection with the secondary instrument panel beam 2.

[0072] The mounting structure is the structure on the main instrument panel beam 1 used to fix environmental components. During the design, it is ensured that key components such as the instrument panel, center console, and steering column can be firmly and accurately fixed on the main instrument panel beam 1, thereby ensuring the consistency and reliability of the installation of these components in different vehicle models.

[0073] Secondly, a standardized male connector 11 is installed at one end of the main instrument panel beam 1 to connect with the secondary instrument panel beam 2. This standardized male connector 11 design not only simplifies the assembly process but also ensures the connection strength and stability between the main and secondary beams, further improving the overall structural reliability and assembly efficiency.

[0074] In some embodiments, step S3 includes: determining the environmental component to be installed on the passenger side based on the configuration information of each vehicle model under development; and determining the arrangement of the environmental component to be installed on the passenger side.

[0075] For example, based on the configuration information of each vehicle model under development, the environmental components that need to be installed on the passenger side are determined, such as the instrument panel, storage box, and air conditioning vents. Next, the specific arrangement of these components on the passenger side is determined, ensuring that their installation location and layout in different models meet their respective configuration and space requirements. Through this process, it is ensured that the interior layout on the passenger side not only meets the specific functional requirements of each vehicle model but also achieves reasonable space utilization and good ergonomic design.

[0076] In some embodiments, step S4 includes: designing the dimensions of the instrument panel sub-beam 2; designing the structure of the instrument panel sub-beam 2; and designing the hard point arrangement of the instrument panel sub-beam 2.

[0077] For example, the dimensions of the instrument panel sub-beam 2 are designed to ensure it can adapt to the specific needs and spatial layout of the passenger side in different vehicle models. Next, the structure of the instrument panel sub-beam 2 is designed, including its shape, thickness, and the layout of reinforcing ribs, to ensure its strength and rigidity under various operating conditions. Finally, the hardpoint arrangement of the instrument panel sub-beam 2 is designed, that is, the positions of each mounting point and fixing point on the sub-beam are determined to ensure that these points can accurately and securely connect to the passenger-side environmental components and other related parts.

[0078] The universal design method for injection-molded instrument panel tube beams of different widths in this invention, through these detailed steps, designs a structurally reasonable and easy-to-install instrument panel sub-tube beam 2 to meet the personalized needs of different vehicle models.

[0079] In some embodiments, the structure of the instrument panel sub-beam 2 includes:

[0080] Design the mounting structure for the environmental components to be installed on the passenger side.

[0081] A female connector that can match the male connector 11 is designed on the instrument panel sub-beam 2.

[0082] For example, the design of the installation structure for environmental components installed on the passenger side ensures that key components such as storage boxes and air conditioning vents can be securely and accurately fixed to the instrument panel sub-beam 2, meeting the specific functional requirements and spatial layout of different vehicle models.

[0083] Secondly, a female connector that can match the male connector 11 is designed on the instrument panel sub-tube beam 2 to ensure that the sub-tube beam can be quickly and reliably connected to the main tube beam.

[0084] The universal design method for injection-molded instrument panel tube beams of different widths in this invention not only improves the installation accuracy and reliability of the passenger-side environmental components, but also simplifies the assembly process and ensures the connection strength and stability between the main tube beam and the auxiliary tube beam.

[0085] In some embodiments, the male connector 11 is provided with a plurality of first through holes, and the female connector is provided with a plurality of second through holes. The male connector 11 is sleeved on the female connector, and the plurality of first through holes correspond one-to-one with the plurality of second through holes. Each first through hole and each second through hole are connected by a rivet.

[0086] The universal design method for injection-molded instrument panel tube beams of different widths in this invention not only ensures precise alignment and stable connection between the male connector 11 and the female connector, preventing relative slippage between them, but also simplifies the connection process compared to traditional welding methods, reduces complex welding procedures, and improves production efficiency and connection reliability.

[0087] It should be noted that after the rivet is fixed, any excess parts on the rivet should be removed.

[0088] In some embodiments, the universal design method for injection-molded instrument panel tube beams of different widths further includes step S5, which designs the instrument panel tube beam mounting bracket. Step S5 includes:

[0089] Based on the structure of the main beam 1 of the instrument panel, a main mounting bracket suitable for the driver's side of various models under development is designed, and support components are designed on the main mounting bracket.

[0090] Based on the layout of the passenger side of each vehicle model under development, a secondary mounting bracket connected to the instrument panel sub-tube beam 2 is designed.

[0091] Based on the structure of the main beam 1 of the instrument panel, a main mounting bracket suitable for the driver's side of various models under development is designed, and support components are designed on the main mounting bracket to ensure that the main mounting bracket can be firmly fixed to the vehicle body, while providing the necessary support and fixing points to adapt to the driver's side requirements of different models.

[0092] Next, based on the layout of the passenger side of each vehicle under development, a secondary mounting bracket connected to the instrument panel sub-beam 2 is designed to ensure that the secondary mounting bracket can accurately align with environmental components and other parts on the sub-beam, meeting the specific functional and spatial requirements of the passenger side of different vehicle models.

[0093] The universal design method for injection-molded instrument panel tube beams of different widths in this invention ensures the installation stability and reliability of instrument panel tube beams in different vehicle models through these detailed design steps, thereby improving the overall assembly quality and efficiency.

[0094] In some embodiments, the universal design method for injection-molded instrument panel tube beams of different widths includes step S6, which involves fabricating and verifying a sample of the instrument panel tube beam. Step S6 includes:

[0095] The main mold for the main mounting bracket is designed and manufactured, and the main mounting bracket is machined onto the main beam of the instrument panel using injection molding process;

[0096] Design and manufacture the secondary mold for the secondary mounting bracket, and use injection molding to process the secondary mounting bracket onto the secondary tube beam of the instrument panel;

[0097] The main instrument panel beam with the main mounting bracket is connected to the secondary instrument panel beam with the secondary mounting bracket.

[0098] For example, design and manufacture the main mold for the main mounting bracket, place the main instrument panel beam inside the mold first, and then use injection molding to machine the main mounting bracket onto the main instrument panel beam 1. Next, design and manufacture the secondary mold for the secondary mounting bracket, place the secondary instrument panel beam into the secondary mold first, and then use injection molding to machine the secondary mounting bracket onto the secondary instrument panel beam 2.

[0099] Finally, the main instrument panel beam 1 with the main mounting bracket is connected to the secondary instrument panel beam 1 with the secondary mounting bracket via a male connector 11 and a female connector.

[0100] The universal design method for injection-molded instrument panel tube beams of different widths according to embodiments of the present invention involves these steps to produce complete instrument panel tube beam prototypes and verify them to ensure that their structural strength, installation accuracy and functional performance meet the design requirements.

[0101] Furthermore, in related technologies, instrument panel tube beams are manufactured through processes such as welding and stamping, which are not only complex but also prone to dimensional deviations and difficult to achieve interchangeability between components. In this application, the main mounting bracket is machined onto the instrument panel tube beam 1 and the secondary mounting bracket onto the instrument panel secondary tube beam 2 using injection molding. This simplifies the production process, improves production efficiency and dimensional accuracy, and facilitates universal design. Moreover, the injection molding process makes the instrument panel tube beam structure more consistent, making it easier to achieve universality and interchangeability between different vehicle models, thereby reducing production costs and increasing design and production flexibility.

[0102] In other embodiments, a standardized tooling is used to limit the movement between the main instrument panel beam 1 and the secondary instrument panel beam 2. Both the main instrument panel beam 1 and the secondary instrument panel beam 2 are straight tubes. This straight tube design ensures a high degree of consistency and accuracy of the instrument panel beams during production, avoiding dimensional deviations and deformation caused by bending. This design not only improves product quality and reliability but also simplifies the production process and reduces manufacturing costs.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
