Description

Technical Field

[0001] This invention belongs to the field of automotive technology. Specifically, this invention relates to an auxiliary device for the production of automotive dashboards, a method for processing automotive dashboards, and an automotive dashboard. Background Technology

[0002] Due to the influence of the interior dashboard design and 3D mesh manufacturing process, the automotive dashboard 3D mesh manufacturing process requires hot pressing and cold pressing processes. This process has limitations on the dashboard design. The dashboard cannot have a large bending curvature surface, which will cause the dashboard design to deform due to the inability to increase its strength on its own, or the hot pressing and cold pressing tooling fixtures cannot be assembled.

[0003] Currently, most 3Dmesh dashboard designs have a large surface curvature, which limits the design freedom compared to slush molding and injection molding dashboards, thus restricting dashboard design.

[0004] During the manufacturing process of 3Dmesh dashboards, the dashboard body skeleton is subjected to enormous closing pressure during the hot and cold pressing stages. The special shape of the dashboard body skeleton makes it impossible for existing tooling to provide support for it. Furthermore, the cavity structure of the dashboard body skeleton is relatively weak, making it prone to deformation under pressure during production, which affects the quality of the dashboard product.

[0005] Chinese patent application number 202210833533.2 discloses a process for covering dashboards with microfiber leather, belonging to the field of automotive interior dashboard technology. The specific steps are as follows: raw material granules are injection molded to form a dashboard skeleton; 3D mesh and microfiber leather are cut according to a standard template, then glue is sprayed on and dried; the dried 3D mesh pieces are then sprayed with glue on another bonding surface and dried; the dried 3D mesh pieces are then bonded to the dashboard skeleton; the dried microfiber leather pieces are then aligned with the 3D mesh pieces on the dashboard skeleton, and the bonding positions of the microfiber leather pieces are positioned on the dashboard skeleton and bonded; finally, hot pressing is performed to activate the glue, enhance the adhesion between the various layers, and simultaneously shape the appearance of the covered part and repair any defects.

[0006] It is desirable to provide an improved auxiliary device for the production of automotive dashboards, particularly concerning the prevention of compressive deformation of the dashboard body frame during dashboard manufacturing. Summary of the Invention

[0051] Example

[0052] Firstly, such as Figures 1 to 7 As shown, this embodiment of the invention provides an auxiliary device for the production of automotive dashboards, including a reinforcing support mechanism for supporting the dashboard upper body frame 8. The reinforcing support mechanism is configured to match the shape of the inner cavity of the dashboard upper body frame 8 and is arranged along the length direction of the inner cavity of the dashboard upper body frame 8. Through the reinforcing support mechanism at the back, the inner cavity of the dashboard upper body frame 8 is filled and supported by the reinforcing support mechanism, effectively solving the pressure deformation problem caused by hot and cold pressing processes during the production of 3D mesh dashboards.

[0053] Specifically, such as Figures 2 to 4As shown, the reinforcing support mechanism includes support sections and positioning connecting sections. Multiple support sections are provided, and adjacent support sections are connected via positioning connecting sections. The support sections are configured to contact the inner wall surface of the instrument panel upper body frame 8 within its internal cavity. The support sections are hollow internally, with internal reinforcing ribs and support surfaces that contact the inner wall surface of the instrument panel upper body frame 8. Multiple internal reinforcing ribs are arranged sequentially and equidistantly along the length of the support section. Multiple pointed reinforcing ribs are provided externally to the support section to provide support for the instrument panel upper body frame 8. The width of each pointed reinforcing rib gradually decreases from one end in the length direction to the other, and one end of the pointed reinforcing rib in the length direction is connected to the support section.

[0054] like Figures 2 to 4 As shown, the positioning connection part is provided with positioning holes and / or screw holes 10. The screw holes 10 are configured to allow screws to pass through, and the reinforcing support mechanism is rigidly connected to the main body frame 8 of the instrument panel by screws. The thickness of the positioning connection part is less than the thickness of the support part, and the thickness direction of the positioning connection part is parallel to the thickness direction of the support part.

[0055] like Figure 1 As shown, two reinforcing support mechanisms are provided: a first reinforcing support mechanism 11 and a second reinforcing support mechanism 12. The length of the first reinforcing support mechanism 11 is shorter than the length of the second reinforcing support mechanism 12. The first and second reinforcing support mechanisms 11 and 12 are arranged sequentially along the length of the instrument panel upper body frame 8 within the inner cavity of the instrument panel upper body frame 8, ensuring reliable support for the supported portion of the instrument panel upper body frame 8. The supported portion of the instrument panel upper body frame 8 has a curved arc structure, and the length directions of the first and second reinforcing support mechanisms 11 and 12 are parallel to the length direction of the instrument panel upper body frame 8. The instrument panel upper body frame 8 also includes a pointed edge portion and a bottom portion. The pointed edge portion is located between the bottom portion and the supported portion, connecting the pointed edge portion to the bottom portion and the supported portion. The bottom portion is located below the supported portion. The pointed edge portion has a V-shaped or U-shaped cross-section. The inner cavity of the instrument panel upper body frame 8 is formed by the pointed edge portion, the bottom portion, and the supported portion.

[0056] like Figure 2 and Figure 3As shown, the first reinforcing support mechanism 11 includes a first support part 2 and a first positioning connection part 3. Multiple first support parts 2 are provided, and adjacent first support parts 2 are connected by the first positioning connection parts 3. Both ends of each first positioning connection part 3 are fixedly connected to two first support parts 2 respectively. The first support parts 2 are configured to contact the inner wall surface of the instrument panel upper body frame 8 within the inner cavity of the instrument panel upper body frame 8. A first support surface 6 is provided on the first support part 2, contacting the inner wall surface of the supported portion of the instrument panel upper body frame 8. The first support surface 6 is the top surface of the first support part 2, and its shape matches the shape of the inner wall surface of the supported portion. The bottom surface of the first support part 2 contacts the bottom portion of the instrument panel upper body frame 8. Each first support part 2 provides support to the instrument panel upper body frame 8 at different positions, ensuring uniform force distribution, strong support performance, preventing deformation of the instrument panel upper body frame 8 under pressure, improving the structural strength of individual instrument panel body components, while also satisfying design freedom and expanding the diversity of interior decoration processes.

[0057] like Figure 2 and Figure 3 As shown, the first support part 2 is a structure with one end open and the other end closed, and is hollow inside. A first internal reinforcing support rib 4 is provided inside the first support part 2. Multiple first internal reinforcing support ribs 4 are arranged sequentially and equidistantly along the length direction of the first support part 2, ensuring uniform stress distribution, strong support performance, and improved overall rigidity. The first internal reinforcing support ribs 4 are fixedly connected to the first support part 2. The length direction of the first support part 2 is parallel to the length direction of the instrument panel upper body frame 8. The first internal reinforcing support ribs 4 extend along the entire width direction of the first support part 2, which is parallel to the width direction of the instrument panel upper body frame 8. The width direction of the instrument panel upper body frame 8 is parallel to the length direction of the vehicle body, and the length direction of the instrument panel upper body frame 8 is parallel to the width direction of the vehicle body. The first internal reinforcing support ribs 4, the first support part 2, and the first positioning connection part 3 are integrally formed, facilitating processing.

[0058] like Figure 2 and Figure 3 As shown, the first support part 2 includes a top wall, a bottom wall, and a connecting wall fixedly connected to the top wall and the bottom wall. The top wall is located above the bottom wall. The first support surface 6 is the top surface of the top wall. The upper end and the lower end of the connecting wall are fixedly connected to the ends of the top wall and the bottom wall, respectively. The first inner reinforcing support rib 4 is located between the top wall and the bottom wall. The top of the first inner reinforcing support rib 4 is fixedly connected to the top wall. The bottom of the first inner reinforcing support rib 4 is fixedly connected to the bottom wall. One end of the first inner reinforcing support rib 4 is fixedly connected to the connecting wall. The other end of the first inner reinforcing support rib 4 is located at the opening end of the first support part 2.

[0059] like Figure 2 and Figure 3 As shown, the exterior of the first support part 2 is provided with first tip reinforcing ribs 5 for providing support to the main body frame 8 of the instrument panel. Multiple first tip reinforcing ribs 5 are provided, and all first tip reinforcing ribs 5 are arranged sequentially along the length direction of the first support part 2 and are equidistantly distributed, so that the force distribution is uniform, the support performance is strong, and the overall rigidity is improved.

[0060] As a preferred option, such as Figure 2 , Figure 3 and Figure 7 As shown, the width of the first pointed reinforcing rib 5 gradually decreases from one end in the length direction to the other. One end of the first pointed reinforcing rib 5 in the length direction is fixedly connected to the closed end of the first support portion 2. The first pointed reinforcing rib 5 extends outward toward the first support portion 2 and is located below the first support surface 6. The number of first pointed reinforcing ribs 5 is greater than the number of first inner reinforcing support ribs 4. In use, the first pointed reinforcing rib 5 is inserted into the inner cavity of the instrument panel upper body frame 8 and is located in the pointed edge portion of the instrument panel upper body frame 8. The first pointed reinforcing rib 5 provides support for the instrument panel upper body frame 8 at the pointed edge portion. This structural design of the first pointed reinforcing rib 5 may help the reinforcing rib better adapt to the shape of the structure into which it is inserted, and may also provide gradually decreasing resistance, making it easier for the first pointed reinforcing rib 5 to be inserted into the predetermined position. The first pointed reinforcing rib 5, the first inner reinforcing support rib 4, the first support portion 2, and the first positioning connection portion 3 are integrally formed, which is convenient for processing.

[0061] like Figure 2 and Figure 3As shown, on the first reinforcing support mechanism 11, two first positioning connection parts 3 are respectively provided with a main positioning hole 13 and a secondary positioning hole 14. The main positioning hole 13 and the secondary positioning hole 14 are through holes that are provided through the first positioning connection part 3 along the thickness direction of the first positioning connection part 3. The main positioning hole 13 and the secondary positioning hole 14 are used to position the first reinforcing support mechanism 11 when it is assembled with the instrument panel body frame 8, so as to ensure that the first reinforcing support mechanism 11 can be accurately and quickly assembled on the instrument panel body frame 8. In use, the first reinforcing support mechanism 11 is rigidly connected to the main body frame 8 of the instrument panel by screws. The screw holes 10 are through holes that extend along the thickness direction of the first positioning connection part 3, allowing screws to pass through. Each first positioning connection part 3 has a screw hole 10, and each first positioning connection part 3 is fixedly connected to the main body frame 8 of the instrument panel by screws. This ensures a more reliable connection between the first reinforcing support mechanism 11 and the main body frame 8 of the instrument panel, and disperses the stress points. It can distribute the force that might otherwise be concentrated at a certain point to a larger area, thereby reducing local stress and the risk of damage, and improving support performance. The thickness of the first positioning connection part 3 is less than the thickness of the first support part 2, and the thickness direction of the first positioning connection part 3 is parallel to the thickness direction of the first support part 2. The thickness direction of the first support part 2 is perpendicular to the length and width directions of the first support part 2. The resulting first reinforcing support mechanism 11 has a concave-convex structure, which makes the force distribution of the first reinforcing support mechanism 11 uniform and improves support performance.

[0062] like Figure 4 and Figure 5 As shown, the second reinforcing support mechanism 12 includes a second support portion 15 and a second positioning connection portion 16. Multiple second support portions 15 are provided, and adjacent second support portions 15 are connected by the second positioning connection portion 16. The two ends of each second positioning connection portion 16 are fixedly connected to two second support portions 15 respectively. The second support portion 15 is configured to contact the inner wall surface of the instrument panel upper body frame 8 in the inner cavity of the instrument panel upper body frame 8. The second support portion 15 is provided with a second support surface 19 that contacts the inner wall surface of the supported part of the instrument panel upper body frame 8. The second support surface 19 is the top surface of the second support portion 15, and the shape of the second support surface 19 matches the shape of the inner wall surface of the supported part. The bottom surface of the second support portion 15 contacts the bottom part of the instrument panel upper body frame 8. Each of the second support parts 15 provides support to the instrument panel body frame 8 at different positions on the instrument panel body frame 8, so that the force distribution is uniform, the support performance is strong, the instrument panel body frame 8 is prevented from being deformed by pressure, the strength of the instrument panel body components is improved, and the design freedom of the shape is satisfied, expanding the diversity of interior process.

[0063] like Figure 4 and Figure 5 As shown, the second support portion 15 has an open end and a closed end, and is hollow inside. A second inner reinforcing support rib 17 is provided inside the second support portion 15. Multiple second inner reinforcing support ribs 17 are arranged sequentially and equidistantly along the length of the second support portion 15, ensuring uniform stress distribution, strong support performance, and improved overall rigidity. The second inner reinforcing support ribs 17 are fixedly connected to the second support portion 15. The length direction of the second support portion 15 is parallel to the length direction of the upper body frame 8 of the instrument panel. The second inner reinforcing support ribs 17 extend along the entire width direction of the second support portion 15, which is parallel to the width direction of the upper body frame 8 of the instrument panel. The width direction of the upper body frame 8 of the instrument panel is parallel to the length direction of the vehicle body, and the length direction of the upper body frame 8 of the instrument panel is parallel to the width direction of the vehicle body. The second inner reinforcing support ribs 17, the second support portion 15, and the second positioning connection portion 16 are integrally formed, facilitating processing.

[0064] like Figure 4 and Figure 5 As shown, the second support portion 15 includes a top wall, a bottom wall, and a connecting wall fixedly connected to the top wall and the bottom wall. The top wall is located above the bottom wall. The second support surface 19 is the top surface of the top wall. The upper end and the lower end of the connecting wall are fixedly connected to the ends of the top wall and the bottom wall, respectively. The second inner reinforcing support rib 17 is located between the top wall and the bottom wall. The top of the second inner reinforcing support rib 17 is fixedly connected to the top wall. The bottom of the second inner reinforcing support rib 17 is fixedly connected to the bottom wall. One end of the second inner reinforcing support rib 17 is fixedly connected to the connecting wall. The other end of the second inner reinforcing support rib 17 is located at the opening end of the second support portion 15.

[0065] like Figure 4 and Figure 5 As shown, the second support part 15 is provided with a second tip reinforcing rib 18 on the outside to provide support for the main body frame 8 of the instrument panel. Multiple second tip reinforcing ribs 18 are provided. All second tip reinforcing ribs 18 are arranged sequentially along the length direction of the second support part 15 and are equidistantly distributed, so that the force distribution is uniform, the support performance is strong, and the overall rigidity is improved.

[0066] As a preferred option, such as Figure 4 , Figure 5 and Figure 7As shown, the width of the second pointed reinforcing rib 18 gradually decreases from one end in the length direction to the other. One end of the second pointed reinforcing rib 18 in the length direction is fixedly connected to the closed end of the second support portion 15. The second pointed reinforcing rib 18 extends outward toward the second support portion 15 and is located below the second support surface 19. The number of second pointed reinforcing ribs 18 is greater than the number of second inner reinforcing support ribs 17. In use, the second pointed reinforcing rib 18 is inserted into the inner cavity of the instrument panel upper body frame 8 and is located in the pointed edge portion of the instrument panel upper body frame 8. The second pointed reinforcing rib 18 provides support for the instrument panel upper body frame 8 at the pointed edge portion. This structural design of the second pointed reinforcing rib 18 may help the reinforcing rib better adapt to the shape of the structure into which it is inserted, and may also provide gradually decreasing resistance, making it easier for the second pointed reinforcing rib 18 to be inserted into the predetermined position. The second pointed reinforcing rib 18, the second inner reinforcing support rib 17, the second support portion 15, and the second positioning connection portion 16 are integrally formed, which is convenient for processing.

[0067] like Figure 4 and Figure 5 As shown, on the second reinforcing support mechanism 12, two second positioning connection parts 16 are respectively provided with a main positioning hole 13 and a secondary positioning hole 14. The main positioning hole 13 and the secondary positioning hole 14 are through holes that penetrate along the thickness direction of the second positioning connection part 16. The main positioning hole 13 and the secondary positioning hole 14 are used to position the second reinforcing support mechanism 12 when it is assembled with the instrument panel upper body frame 8, so as to ensure that the second reinforcing support mechanism 12 can be accurately and quickly assembled on the instrument panel upper body frame 8. The instrument panel upper body frame 8 is provided with positioning pins for inserting into the main positioning hole 13 and the secondary positioning hole 14. In use, the second reinforcing support mechanism 12 is rigidly connected to the instrument panel body frame 8 via screws. The screw holes 10 are through holes extending along the thickness direction of the second positioning connection portion 16, allowing screws to pass through. Each second positioning connection portion 16 has screw holes 10, and each second positioning connection portion 16 is fixedly connected to the instrument panel body frame 8 via screws. This ensures a more secure connection between the second reinforcing support mechanism 12 and the instrument panel body frame 8, and disperses the stress points. Force that might otherwise be concentrated at a single point is distributed over a larger area, thereby reducing localized stress and the risk of damage, and improving support performance. The thickness of the second positioning connection portion 16 is less than the thickness of the second support portion 15, and the thickness direction of the second positioning connection portion 16 is parallel to the thickness direction of the second support portion 15. The thickness direction of the second support portion 15 is perpendicular to its length and width directions. The resulting second reinforcing support mechanism 12 has a concave-convex structure, ensuring uniform force distribution and improving support performance.

[0068] The aforementioned automotive dashboard production auxiliary device is designed with two reinforcing support mechanisms on the left and right sides. These mechanisms are made of PA6-GF50 (nylon 6 with 50% glass fiber) material, which provides good dimensional stability under heat and stress. The dimensions of these reinforcing support mechanisms match the inner cavity of the dashboard's main frame 8, and main positioning holes 13 and secondary positioning holes 14 are arranged on both sides for positioning. The overall structure of the reinforcing support mechanism is designed with a concave-convex feature, with a pointed reinforcing rib added to the top of the outer side to support the tip of the main frame. A closing rib is added to the cavity on the back of the convex feature. The overall concave-convex structure and reinforcing rib design of the reinforcing support mechanism not only make the structure strong and stable, but also reduce its overall weight and facilitate molding.

[0069] The support mechanism is rigidly connected to the instrument panel frame 8 by screws, and the back cavity of the instrument panel frame 8 is designed to conform to the shape, which strengthens the internal cavity structure of the instrument panel frame 8 and prevents product appearance quality problems caused by structural deformation during hot pressing and cold pressing processes, while improving the pass rate of single production pieces.

[0070] Strengthening the support structure not only meets the current project's new styling requirements but also satisfies the strength requirements of the 3Dmesh dashboard's frame during hot and cold pressing processes. This prevents the dashboard frame from deforming under pressure, improves the structural strength of individual dashboard components, and simultaneously allows for greater design freedom and expands the diversity of interior manufacturing processes, enabling the 3Dmesh dashboard to achieve diverse styling.

[0071] Secondly, embodiments of the present invention also provide a method for manufacturing an automotive dashboard, employing an automotive dashboard production auxiliary device with the above-described structure, and comprising the following steps:

[0072] S1. Assemble the automotive dashboard production auxiliary device with the dashboard body frame 8.

[0073] S2. Assemble the 3Dmesh layer 7 with the main body skeleton 8 on the dashboard;

[0074] S3. Assemble the dashboard covering layer 9 and the 3D mesh layer 7 to form the dashboard body assembly;

[0075] S4. The instrument panel assembly is hot-pressed.

[0076] S5, the instrument panel assembly is cold-pressed.

[0077] like Figure 6 and Figure 7As shown, in step S1 above, the first reinforcing support mechanism 11 and the second reinforcing support mechanism 12 are inserted into the inner cavity of the instrument panel upper body frame 8. The positioning pins on the instrument panel upper body frame 8 are respectively inserted into the main positioning hole 13 and the secondary positioning hole 14 of the first reinforcing support mechanism 11 and the second reinforcing support mechanism 12. After positioning is completed, the first reinforcing support mechanism 11 and the second reinforcing support mechanism 12 are fixed to the instrument panel upper body frame 8 with screws. The inner cavity of the instrument panel upper body frame 8 is filled and supported by the first reinforcing support mechanism 11 and the second reinforcing support mechanism 12.

[0078] In step S2 above, the 3Dmesh layer 7 is bonded to the main body skeleton 8 on the dashboard with adhesive, and then cooled for 20 minutes.

[0079] In step S3 above, the dashboard covering layer 9 and the 3D mesh layer 7 are bonded together with adhesive. The 3D mesh layer 7 is located between the dashboard covering layer 9 and the dashboard upper body frame 8. The dashboard covering layer 9 is made of PVC (polyvinyl chloride).

[0080] In step S4 above, the instrument panel body assembly is subjected to hot press tooling to activate the adhesive.

[0081] In step S5 above, the instrument panel assembly enters a cold-press tool to cure the adhesive, ensuring product stability and completing the production of the automotive instrument panel.

[0082] The automotive dashboard processing method provided in this embodiment of the invention has the same technical effect as the automotive dashboard production auxiliary device provided in this embodiment of the invention, and will not be described again here.

[0083] Thirdly, embodiments of the present invention also provide an automotive dashboard, which is manufactured using the aforementioned automotive dashboard manufacturing method. It achieves the same technical effects and will not be elaborated further here.
