Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and particularly to an automobile interior instrument panel. Background Art

[0002] As an important integrated component of functions and decorations inside a vehicle, the design of an automobile instrument panel (IP) needs to take into account the aesthetic appearance, function adaptability, and production economy. In the platform-based development of multiple automobile models, the instrument panel needs to meet the appearance differentiation requirements of different models, and at the same time, the core components should be made as universal as possible to reduce the development cost and shorten the cycle. The traditional instrument panel design usually adopts an integral development mode, and the core difficulty lies in how to achieve a balance among the body structure, styling constraints, and multi-model adaptability.

[0003] In the prior art, the platform-based design of an automobile instrument panel mainly realizes the generalization of components by unifying the interfaces of peripheral components such as the body front panel, chassis, and air conditioner. Specifically, the instrument panel system includes components such as an IP skeleton, an IP upper body, a front panel trim, a decorative panel, and an air-conditioning vent. Its installation interfaces need to be strictly matched with peripheral components such as the body front panel, windshield curvature, and steering column. For example, the instrument panel body is connected to the vehicle body through fixed points, the front panel trim needs to fit the body gutter and the contour of the front windshield, and components such as the decorative panel and the guard plate are fixed to the main body of the instrument panel through standardized snap joints or screw structures. To achieve generalization, the prior art requires that the body structures, styling boundaries, and peripheral component interfaces of models within the platform are completely the same. Otherwise, the instrument panel components cannot be directly reused.

[0004] The prior art has the following technical problems: First, the generality of the instrument panel among models of the same platform in the prior art is poor. Due to overly strict requirements for the body size, styling, and the layout and interfaces of peripheral components, it is difficult for different models, even those belonging to the same platform, to directly use the same instrument panel, increasing the development cost and cycle. Second, the prior art is difficult to meet the requirements of rapid model iteration and diverse styling. With the intensification of competition in the automobile market, consumers' personalized requirements for the appearance of models are increasing day by day. Automobile manufacturers need to launch multiple models with different styles in a short period of time. However, the traditional instrument panel development mode cannot quickly adapt to this change and cannot achieve flexible adjustment and rapid update of the styling. In addition, the prior art faces the problem of repeated investment when developing right-hand drive models. Due to the lack of consideration of the generality between left-hand drive and right-hand drive models, it is necessary to redesign some components when developing right-hand drive models, increasing the development cost and time cost. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technologies, the purpose of the embodiments of the present invention is to provide an automotive interior instrument panel. Through standardized interface design, while retaining the commonality of some large-investment components, only by developing a small number of differentiated components, the interchange and iterative upgrade of the instrument panel among multiple models on the same platform can be realized, reducing the development cost and cycle. At the same time, it meets the diverse styling requirements of models and improves the flexibility and economy of the automotive interior instrument panel design.

[0006] To achieve the above object, the embodiments of the present invention provide the following technical solutions:

[0007] An automotive interior instrument panel is installed on the instrument panel crossbeam and includes an instrument panel body, a front apron trim panel, a decorative panel, and components below the waistline; the installation interface between the instrument panel body and the instrument panel crossbeam is arranged in a standardized manner; the front apron trim panel is detachably installed at the front end of the instrument panel body, and the position and structure of the installation interface of the front apron trim panel are symmetric with respect to the XZ plane; the decorative panel and the components below the waistline are respectively connected to the instrument panel body through standardized installation interfaces, and the standardized installation interfaces are adapted to replace decorative panels or components below the waistline with different shapes.

[0008] Optionally, the installation interface of the front apron trim panel includes at least one standardized structure among snap connection, welding, or screw fixation, and the contour of the front apron trim panel is adapted to the curvature, width, and height changes of the front windshield of different models.

[0009] Optionally, the decorative panel is installed on the instrument panel body, and the position and structure of the installation interface between the decorative panel and the instrument panel body are the same. The decorative panels of different models obtain different appearance instrument panels through changes in color patterns.

[0010] Optionally, the components below the waistline include a lower left guard plate, a middle lower guard plate, and a glove box. The installation interface positions and structures of the three with the instrument panel body are the same, and the shapes are adapted to the differences in the areas below the waistline of different models.

[0011] Optionally, the front apron trim panel is independently replaced to adapt to the changes in the front windshield and the body water trough of different models, and the remaining components are shared.

[0012] Optionally, instrument panels with different shapes are adapted to different models by interchanging the front apron trim panels, and are paired with the A-pillar guard plates and door guard plates of the corresponding models.

[0013] Optionally, the decorative panel is independently replaced with a decorative panel of a different shape, or the components below the waistline are independently replaced with a lower left guard plate, a middle lower guard plate, and a glove box of different shapes, and the installation interface remains consistent with the instrument panel body.

[0014] Optionally, the front apron trim panel, the decorative panel, and the components below the waistline are combined and replaced to form instrument panel assemblies with different shapes.

[0015] Optionally, the instrument panel implements the following combined changes:

[0016] Only by newly opening the front apron trim, it can cope with the different curvatures, widths and heights of the body gutter and the front windshield, and other components are shared; or, by newly opening the front apron trim and simultaneously newly developing the instrument panel decorative panel, other components are continued to be used; or, by newly opening the front apron trim and simultaneously newly developing the components below the waistline, other components are continued to be used.

[0017] Optionally, the above combined changes are applied to different vehicle models within the platform to achieve the overall interchange or partial structure continuation of the instrument panel, including: through the new development of the front apron trim, different shaped instrument panels can be interchanged and applied to different vehicle models, and are matched with their respective shaped A-pillar trims and door trims; on the basis of the new development of the front apron trim, a decorative panel is newly developed to achieve different appearance instrument panels, and other components are shared, and different vehicle models within the platform are used differently; on the basis of different shaped instrument panels, the components below the waistline are completely shared.

[0018] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0019] 1. The automotive interior instrument panel of the present invention includes an instrument panel body, a front apron trim, a decorative panel and components below the waistline. The instrument panel body is connected to the instrument panel crossbeam through a standardized interface arrangement. The front apron trim is detachably installed at the front end of the body, and its interface position and structure are symmetric with respect to the XZ plane. The decorative panel and components below the waistline are connected to the body through standardized interfaces. Through the standardized interface design, on the basis of retaining the commonality of some large-investment components, only by developing a small number of differentiated components, the interchange and iterative upgrade of the instrument panel among multiple vehicle models on the same platform can be realized, reducing the development cost and cycle, while meeting the diverse styling requirements of vehicle models, and extending to the development of right-hand drive vehicle models, enhancing the flexibility and economy of the automotive interior instrument panel design.

[0020] 2. The present invention breaks through the constraints on the body size and styling design, and only modifies individual decorative parts to adapt to the changes of the body and the styling requirements. Compared with developing a new set of instrument panels, it saves the one-time investment cost and greatly shortens the development and verification cycle, realizing the rapid iteration of vehicle model styling and the styling change requirements.

[0021] 3. Through the standardized installation, fixing and matching structure, when a single set of shaped instrument panel is interchanged among vehicle models within the platform, only the front apron needs to be newly developed to adapt to different outer boundaries, and other components can be replaced with each other within a single shape regardless of the number of types developed, or the overall interchange of different shaped instrument panels can also be realized only by newly developing the front apron trim. The investment is small and the development cycle is short.

[0034] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0035] Embodiment 1

[0036] This embodiment proposes a platformized design scheme for an automotive instrument panel. Through the differential design of very few components on the instrument panel, such as the front panel trim, and the flexible instrument panel crossbeam design, platform sharing is achieved. The layout requirements for the vehicle body front panel, windshield curvature and angle, and chassis components such as the steering column and air conditioning are relatively loose, and only the standardized design of the installation interface structure is required.

[0037] The appearance parts of the instrument panel include the front panel trim, the main body, the decorative panel, the end plate, the air conditioning vent, the glove box, the left, middle, and lower right guard plates, etc. The peripheral parts include the instrument panel crossbeam, the front windshield, the vehicle body, the steering column, the combination switch, the air conditioning, the A-pillar guard plate, the door guard plate, the door seal strip, etc.

[0038] In order to achieve the maximum savings in investment (otherwise, a new development of the instrument panel body is required, and the investment in molds, tooling, gauges, and tests cannot be saved), it is necessary to:

[0039] 1. The installation interface positions within the IP system and with peripheral components are fixed, the structure is standardized, and they can be used interchangeably. Moreover, it is necessary to design symmetrically left and right with the XZ plane (the left-right symmetry plane) as the reference. For example: the installation point positions of the front fascia and the instrument panel body within the system are fixed and symmetrical, the interface structure is standardized, and the installation positions and structures of the decorative panel and the components below the waistline with the instrument panel body are the same; across systems, such as the installation point positions of the instrument panel body and the vehicle body are fixed and symmetrical left and right, and the installation structure is a standardized design; the installation positioning distribution and the fixing structure of the instrument panel body and the instrument panel crossbeam (CCB) are standardized, etc.;

[0040] 2. The instrument panel styling requires a separate component of the front fascia.

[0041] In the present invention, A1 and A2 are only examples of the instrument panel styling of different types of vehicles within the same platform (such as Figure 1 , Figure 2 , Figure 3 , Figure 4 ). In actual development, the number of vehicle types within the same platform is usually greater than or equal to two. All the following descriptions are only exemplified by A1 and A2 as two examples.

[0042] For example: If vehicle type A1 within the same platform is positioned as mid - to - high - end and vehicle type A2 is positioned as mid - range. Then, a set of styling is developed first on A1. After the A1 vehicle type is applied, local differential design is done for A2 to achieve visual differentiation; or, when the styling of vehicle type A1 is updated and iterated, its original styling is directly used for vehicle type A2; or, vehicle types A1 and A2 each have their own styling, and the styling can be interchanged and used only through the change of some components;

[0043] The automotive interior instrument panel includes an instrument panel body, a front fascia, a decorative panel, and components below the waistline; the installation interface between the instrument panel body and the instrument panel crossbeam is arranged in a standardized manner; the front fascia is detachably installed at the front end of the instrument panel body, and the installation interface position and structure of the front fascia are symmetrical with the XZ plane as the reference; the decorative panel and the components below the waistline are respectively connected to the instrument panel body through standardized installation interfaces, and the standardized installation interfaces are adapted to replace decorative panels or components below the waistline with different styling.

[0044] Through the standardized interface design, the styling appearance can be changed by developing only some components. Larger investment components such as the IP skeleton and the upper IP body can be kept common, or only the components below the waistline can be kept common and used in a flexible combination. This can reduce investment costs (such as the IP skeleton, etc.) and shorten the development cycle (such as the static explosion test verification cycle of the co - driver airbag, etc.). The platform - based design of this instrument panel is applicable to many vehicle types, can be extended to the development of right - hand - drive vehicle types, can realize the overall interchange of instrument panels between vehicle types of the same platform, and can also realize the complete reuse of some structures of the instrument panel between vehicle types of the same platform.

[0045] The installation interface of the front fascia includes at least one standardized structure such as snap connection, welding or screw fixation, ensuring its detachable and interchangeable properties. The contour of the front fascia adapts to the curvature, width and height changes of the front windshield of different vehicle models. By replacing the front fascia, different vehicle body boundaries can be matched without redeveloping the entire instrument panel, solving the problem of poor versatility caused by differences in the front windshield and body gutter, reducing the development workload caused by vehicle model differences, and significantly reducing the development cost.

[0046] The decorative panel is installed on the instrument panel body, and the installation interface positions and structures of the decorative panel and the instrument panel body are the same. The decorative panels of different vehicle models obtain different appearance instrument panels through changes in color patterns and textures (such as INS, water transfer printing and other processes).

[0047] The versatility of the interface allows the decorative panel to be developed independently, avoiding the need to redesign the overall structure due to styling changes, and shortening the development cycle. By changing the color patterns and textures of the decorative panel, different appearance instrument panels can be obtained, meeting the aesthetic needs of different consumers and the positioning differences of vehicle models. This design not only enhances the market competitiveness of the product, but also makes the update and replacement of the decorative panel more convenient, reducing the production cost.

[0048] The components below the waistline include the lower left guard panel, the middle lower guard panel and the glove box. The installation interface positions and structures of the three with the instrument panel body are the same, and the styling adapts to the differences in the areas below the waistline of different vehicle models.

[0049] The components below the waistline (lower left guard panel, middle lower guard panel and glove box) are connected to the instrument panel body through the same standardized interface, and their styling adapts to the differences in the areas below the waistline of different vehicle models. This design allows only the components below the waistline to be replaced to meet the styling requirements of different vehicle models, while retaining the versatility of the body and other components, solving the problem that components cannot be shared due to styling differences in the waistline area.

[0050] The front fascia is independently replaced to adapt to the changes in the front windshield and body gutter of different vehicle models, and the remaining components are shared.

[0051] The front fascia can be independently replaced to adapt to the changes in the front windshield and body gutter of different vehicle models, while the remaining components such as the instrument panel body, the decorative panel and the components below the waistline can be shared. This design enables, when developing a new vehicle model, the entire instrument panel not to be redesigned and developed, but only the front fascia to be adjusted, avoiding the problem of overall development due to differences in vehicle body boundaries, shortening the development cycle, and reducing the mold investment and test verification costs.

[0052] Instrument panels with different styling adapt to different vehicle models by interchanging the front fascia, and are paired with the A-pillar trim and door trim of the corresponding vehicle models.

[0053] By replacing the front apron trim, it is possible to achieve the matching of instrument panels with different shapes to different vehicle models. At the same time, the A-pillar trim and door trim corresponding to the vehicle model are matched to meet the requirements of the overall vehicle appearance design, solving the problem that the instrument panel cannot be used across vehicle models due to shape differences. This interchangeable design not only improves the versatility of the instrument panel, but also enables the same instrument panel system to be applied to multiple vehicle models. At the same time, through the combined design, the appearance coordination is ensured, the flexibility of the platform design is improved, the repetitive work in the R & D and production processes is reduced, and the production efficiency and resource utilization rate are improved. At the same time, this modular replacement method is also convenient for later maintenance and replacement, improving the maintainability of the product.

[0054] The decorative panel is independently replaced with decorative panels of different shapes, or the components below the waistline are independently replaced with different-shaped lower left guards, middle lower guards, and glove boxes, and the installation interfaces are consistent with the instrument panel body.

[0055] When implementing instrument panels with different shapes, the decorative panel can be independently replaced with decorative panels of different shapes, or the components below the waistline can be independently replaced with different-shaped lower left guards, middle lower guards, and glove boxes. During the replacement process, the installation interfaces of these components are consistent with the instrument panel body, ensuring the convenience and reliability of installation. This design provides greater flexibility and diversity for the product, and can better meet the needs of the market and consumers.

[0056] The front apron trim, decorative panel, and components below the waistline are combined and replaced to form instrument panel assemblies with different shapes. This combined replacement method provides more creative space, and a rich variety of instrument panel shapes can be achieved through different component combinations. At the same time, since the installation interfaces of each component are standardized, this combined replacement will not affect the overall structural stability and functionality of the instrument panel, ensuring the quality and performance of the product.

[0057] The instrument panel has at least the following three combinations of changes:

[0058] Only by newly opening the front apron trim, dealing with the different curvatures, widths, and heights of the body's water trough and the front windshield; other components of this set of instrument panel shapes can be completely shared; all vehicle models within the platform can be applied.

[0059] By newly opening the front apron trim, dealing with the different curvatures, widths, and heights of the body's water trough and the front windshield; the instrument panel decorative panels (the first decorative panel and the second decorative panel) are newly developed according to different shape requirements, such as: the decorative panel or the upper decorative panel of the waistline part has shape and process changes, and is newly developed as a differential part, but its installation interface on the instrument panel body is the same. Other components are completely reused to achieve the overall shape difference; all vehicle models within the platform can be applied.

[0060] By opening a new front fascia, it is necessary to cope with the different curvatures, widths, and heights of the body's water trough and the front windshield; for the parts below the waistline of the instrument panel, new development is carried out according to different styling requirements, and other parts are completely reused; for example, parts such as the lower left guard, the middle lower guard, and the glove box have styling and process changes and are newly developed as differential parts. However, their installation interfaces on the main body of the instrument panel are the same. All models within the platform can be applied.

[0061] On the basis of the above three basic change combinations, reduce the development scope or appropriately increase the development scope to form new combination forms, which are applicable to different models within the same platform. Different instrument panel styles can adopt any one or more of the above combination change forms for different models within the platform. For the internal parts of the instrument panel system that involve the matching of peripheral parts (such as the front fascia, decorative panel, end plates, left and right lower guards, etc.), the boundary dimensions can be matched with the same set of A-pillars, door trim panels or different styling A-pillar trim panels, door trim panels according to the styling requirements.

[0062] Specifically:

[0063] Instrument panel body 1.2: Generally, there are 4 to 5 fixing points of the instrument panel body 1.2 on the body's front apron. Since the instrument panel bodies A1 and A2 share the same platform, the installation points 1-4 on the body are fixed in layout, symmetrical with respect to the XZ plane, and the interface structure is standardized (such as Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 10 shown). Such a standard interface design can avoid the quality risks brought by diversified designs and save relevant verification rounds (improve the first-pass yield rate). Secondly, the installation brackets of the instrument panel body 1.2 on this platform model are all shared, and only one set of bracket molds can be developed and arranged separately to save relevant mold investment ( Figure 5 , Figure 10 ). Thirdly, the layout position and the installation structure itself are symmetrically distributed, and the right-hand drive of the parts in this part of the body does not require new development, which also saves the right-hand drive development investment and shortens the development cycle of this part.

[0064] The installation point positions of the instrument panel body 1.2 on the instrument panel crossbeam are generally the same, and there are generally 12 to 20 installation points, such as Figure 5 , Figure 6 , Figure 7 , and the installation point numbers are 5 to 20 (among them, 7, 12, 13, and 14 are symmetrically arranged left and right). During the actual development process, the number of installation points arranged can be appropriately increased or decreased according to the styling and layout requirements, and the position can also be adjusted within a local area, but the installation structure is a standardized structure (such as Figure 11 shown), and it supports the use of the same fasteners (to facilitate co-line production), and the peripheral contour follows the styling development. Support the instrument panel together with the instrument panel crossbeam within the platform ( Figure 10The middle component B) is used interchangeably together. Among them, the design of symmetrically arranged mounting points provides conditions for the universal use of the left and right rudders of the relevant brackets on the instrument panel crossbeam, reducing the development cost of the relevant mounting brackets on the instrument panel crossbeam.

[0065] The instrument panel is designed with a front apron trim panel 1.1. Since the water trough on the vehicle body, the curvature, width and height dimensions of the front windshield may vary within the same platform models, the design of the front apron trim panel can reduce the investment of the instrument panel and shorten the development cycle, which is a key component for realizing the platform design of the instrument panel. It is stably and reliably installed on the instrument panel body 1.2 (as Figure 8 shown). Its installation structure includes but is not limited to forms such as snap connection, welding and screw fixation. These structures and positions are all standardized structures; even if the front apron trim panel 1.1 needs to be developed in multiple sets to match the changes in the water trough on different vehicle bodies and the contour dimensions of the front windshield within the same platform, each set of it can still be interchangeably used on the instrument panel body. The specific implementation method is as follows: the contour and mounting points of the front apron trim panel 1.1 are symmetrically arranged with the XZ plane as the reference, and the mounting point positions are fixed, ensuring that the installed part, the instrument panel body 1.2, can be shared after being newly developed with the changes in the boundaries of other models within the platform, and the front apron trim panel 1.1 can also be shared by the left and right rudders.

[0066] Similarly, other components installed on the instrument panel body, such as the first decorative panel 2, the second decorative panel 4, the air-conditioning air outlet 3, the end plate 5, the lower left guard plate 7, the middle lower guard plate 8, the glove box 9 (lower right guard plate), and the combined instrument cover 10, are all installed on the instrument panel body 1.2. However, no matter which installation structure is adopted, their positioning, mounting point positions and structures are the same. These components can still ensure the sharing of the instrument panel body 1.2 after being newly developed according to the styling requirements.

[0067] The arrangement angle and position of the steering column within the same platform generally do not change much. The steering column shroud 6 is installed on the steering column. Based on the standardized design of its installation and positioning structure on the steering column and the combination switch and its matching structure with the steering wheel, it can basically be made universal within the same platform. However, considering that there may be sedans and SUVs within the same platform and the sitting postures vary greatly, in this case, the steering column shroud can be developed according to the actual situation. It may be necessary to develop two sets, or only the upper shroud may be newly developed, or only the lower shroud may be developed, which are respectively applicable to sedans and SUVs.

[0068] In the example, for the two instrument panel styles A1 and A2, although their appearances are quite different, the following several combinations can be realized and applied to different vehicle types within the platform:

[0069] I. Through the new development of the front panel A1-1.1, its outer contour is made the same as A2-1.1, so that the A1-shaped instrument panel can be used on the A2 model; similarly, the A2-shaped instrument panel can also be newly developed through its A2-1.1 front panel (with the outer contour the same as A1-1.1) so that the A2-shaped instrument panel can be installed on the A1 model; thus, the two sets of shaped instrument panels can be interchangeably used on different types of models within the platform (see Figure 9 ).

[0070] Generally, for the interchangeable use of large instrument panel shapes, the respective shaped A-pillar trim panels and door trim panels are matched;

[0071] II. On the basis of the above combination 1, the first decorative panel 2 and the second decorative panel 4 can be newly developed according to different shaping and process requirements, such as changes in color patterns, different processes such as INS, water transfer printing, painting, wrapping, etc., and different appearance instrument panels can be obtained after the new development. Other components are shared, and different models within the platform can be used differentially.

[0072] For example: By only changing the first decorative panel 2 and the second decorative panel 4, it can be used on different models based on the A1-shaped instrument panel; by only changing the first decorative panel 2 and the second decorative panel 4, it can be used on different models based on the A2-shaped instrument panel; by superimposing combination I, it can be interchangeably used for all models within the platform;

[0073] III. On the basis of the two completely different shapes of the above instrument panel A1 and instrument panel A2, the components below the waistline can be completely shared. That is, the left lower guard plate 7 of the A1 model and the A2 model can be completely the same in terms of shape, positioning, installation and fixing structure, etc. (i.e., produced by the same set of molds, toolings, and inspection tools, without any differences); similarly, the middle lower guard plate 8 and the glove box of the A1 model and the A2 model can also be completely the same components respectively. In this way, at least the investment in the relevant molds, toolings, and inspection tools for three shaped parts and the relevant test costs are saved, and these parts can be shared across the entire platform.

[0074] The above only lists three different combination forms to achieve that different shaped instrument panels can be shared among different types of models within the platform, and the actual application is more flexible. And the relevant internal structures of the instrument panel, such as the air duct, etc., do not need to be newly developed either, and only one set needs to be developed following their respective shapes.

[0075] Although the specific implementation manners of the present invention are described above in conjunction with the accompanying drawings, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that various modifications or deformations that can be made without creative efforts based on the technical solutions of the present invention are still within the protection scope of the present invention.
